Oreos have been one of the most popular cookies over the years, but many people wonder, are Oreos vegan? It is true that they have an incredible flavor and are cheap, that's why we all want to try them.
If you are a vegan person with an uncontrollable desire to try these cookies until now, we bring the answers to all your questions. Are Oreos vegan friendly? Find out here.
What and how is vegan food?
Every vegan food, product, or food doesn't contain ingredients of animal origin. They don't just avoid consuming meat but of all those products derived from animals such as eggs, dairy, and even different types of flour.
When a person decides or desires to modify his lifestyle and start veganism, they tend to say goodbye to certain foods. However, this does not mean you have to say goodbye to them forever.
Today vegan food has evolved in such a way that vegetarians have many more options to choose from. Many famous food brands have joined the inclusion, creating completely vegan-friendly food lines.
Are Oreos vegan friendly?
Believe it or not, Oreos has always been vegan. This happened accidentally in traditional Oreos, and since then, the formula has not changed. So if you have resisted the desire to eat these delicious cookies until now, you will be delighted to know that Oreos are vegan.
However, despite being proven that none of its ingredients are of animal origin, the companies alert the public to be vigilant. Although not part of the composition, Oreos may have traces of milk.
This is the only reason Oreos are not certified vegan-friendly. Since in the machines and utensils that they use to manufacture each batch of their products, they cannot guarantee that they are 100% free of milk.
So, are Oreos vegan or not? Yes, its composition does not have ingredients of animal origin. But the only possible trace of milk comes from the machinery they use.
Oreos cookies ingredients
Cocoa cookies [wheat flour, sugar, palm fat, fat-reduced cocoa (4.5%), water, glucose syrup, salt, raising agent (sodium carbonates), flavoring], reconstituted skimmed milk powder, sugar, pieces cocoa biscuit [wheat flour, sugar, rapeseed oil, fat-reduced cocoa (0.4%), glucose-fructose syrup, wheat starch, palm fat, raising agents (potassium carbonates, ammonium carbonates, sodium), salt, emulsifier (soya lecithin), flavoring], coconut fat, cream (2.5%), glucose syrup, whey powder, skimmed milk powder, emulsifier (mono- and diglycerides of fatty acids ), stabilizers (locust bean gum, guar gum), aroma.
Is it safe to eat Oreos for vegan people?
As the company states, each batch of Oreo cookies they make has a 0.01% chance of having traces of milk. But in reality, its ingredients are entirely vegan.
We hope we have answered your questions about whether they are vegan-friendly Oreos and that you can enjoy them as many times as you want. Therefore, if you're going to put aside the slightest possibility, you can add these delicious cookies to your daily vegan diet.
However, the Oreo company does not recommend the consumption of its cookies for vegan consumers since there is the slightest possibility of containing traces of milk due to direct contact with the machinery.
Oreos varieties than aren't vegan friendly
Ahora, solo las galletas Oreo originales y las gluten-free pueden considerarse accidentalmente veganas. Porque existen otro tipo de variaciones que no lo son, ya que contienen leche. Por ejemplo, las Oreo fudge o cualquier que esté cubierta con algún tipo de chocolate o producto lacteo.

HTML image maps - an old trick with a new twist
HTML image maps have been around for some time but not many people are familiar with them. In fact, until a client recently wanted to use an image as the basis of a dynamic help system, even I didn't have much use for them. But when you do need to work with them, it's actually a lot of fun!
So what's the twist? This article shows how one can use image maps without the anchor tag which is normally used, uses a little jQuery, and is written in the context of Apex - all at the same time. You can check out the demo here. Here are the basic steps to get you going...
 1. Install jQuery.
 2. Get the image. There are a bunch of programs out there, both free and paid, that will help you take screen shots if you don't already have the image you want to work with. For a free tool that comes with Vista, check out the snipping tool.
 3. Create a map for the areas in the image. In an HTML image map, the sections one will be working with are called areas and each area element has a shape attribute. There are three basic shapes: rect (rectangle), circle, and polygon. Choose the appropriate shape for each each area of the image you want to work with - polygons can be used for oddly shaped areas. Then using a tool for working with images, like MS Paint or GIMP, get the coordinates of each. Each shape has its own system for mapping coordinates. We'll turn these coordinates into code in step 5.
 4. Make the image available to your application. Either add the image to the shared components of your application or to the file system of your web server like the "i" directory.
 5. Add the image and image map to your Apex application by adding an HTML region with the following code (modify for your needs):
 6. Add the following JavaScript to the HTML Header of the page:
As you can see, my implementation is very basic - all the HTML is in the one region. However, there is no limit to how you can adapt the code for your own needs. Using a static region ID, you can work with multiple regions. Even Ajax is possible.
Happing coding!

text: The aim of this research was to explore why workers in health and social services embarked on a Certificate in Community Care Practice and the extent to which they felt knowledge learnt related to their every‐day work practice. The objective was to indicate how useful more academic courses are for health and social care staff, and to find out the kinds of barriers to practicing theory learnt in the classroom students face in their 'real world' of work. Data was collected from 25 mature students (over half were between the ages of 41–50 years), 3 of whom were men from a range of professional backgrounds including; support staff working in residential and domiciliary services and informal (unpaid) carers for people with learning disabilities, mental health difficulties as well as older people. Quantitative (an adapted questionnaire) and qualitative (focus group session which was an integral part of classroom learning about research methodology) methods were employed. Data was analysed using SPSS and thematic analysis. Findings indicated that the main motivators for study was to gain a qualification and for personal development. Students reported their increased desire to link theory learnt which they found highly relevant to their everyday practice, but organisational barriers sometimes precluded them from doing so. The paper ends with policy and practice recommendations.

The South Texas Blood & Tissue Center celebrates Black History Month in February by shedding light on Charles Drew, who is considered the inventor of blood banking.
During Dr. Drew's residency at Columbia University's Presbyterian Hospital in the 1940′s, Drew developed a technique for the long term preservation of blood plasma. By separating the liquid part of blood (plasma) from the whole blood (the part containing the red blood cells) and refrigerating them separately, he could combine them up to a week later for transfusion.
STBTC still uses Dr. Drew's method of separation to break each unit of blood donated into several components, helping as many as three patients with a donation from one donor. A patients like Chris Pinkerton who suffers from Sickle Cell Anemia and needs blood transfusions often benefits from blood donors.
With the advanced research and technology, red blood cells now have a shelf life of 42 days and plasma can be frozen and stored for a year. To donate blood and save a life visit our website at _URL_

BAYOU, TX (SAN PATRICIO COUNTY)
BAYOU, TEXAS (San Patricio County). Bayou, between San Patricio and Mathis on a bayou that drained an area of fertile San Patricio County land, was settled in the post-Civil War period. Thomas Bernard Magowan settled on a farm on the bayou in 1876, and other families followed until perhaps a dozen lived in the area. The community had its own school, administered by the schools of San Patricio, and the loose community of families considered themselves a settlement apart from San Patricio. The later history of Bayou is unknown; most of its area is now ranchland.

Connecting dots with straight line in a loop.
15 views (last 30 days)
Hi all,
I have a question regarding connecting the dots.
Suppose I have the following sample data points:
example.png
I have a while-loop that identifies the first, second, and fourth points in the figure.
I know their index numbers and their (x,y) values.
Pictorially, I would like to connect with a straight line, the aforementioned points.
What is the best way of doing this?
My gut feeling is to input the "draw" code within the while-loop I have so each time I obtain the index of the next point I want to connect, I simply connect to that pictorially. But how to go about this?
Thanks in advance!

It seems that no one is exactly sure what you want to do, since the super obvious plot(x,y,'b-') doesn't seem to be it.
So I'll throw out a couple of guesses.
To close the figure (if that's what you want) you can tack the first point onto the array:
xp = [x, x(1)];
yp = [y, y(1)];
plot(xp, yp, 'b.-', 'LineWidth', 2, 'MarkerSize', 18);
grid on;
To make a bunch of points in between, you'd have to use polyfit and polyval() for each segment. Here it is for one segment with endpoints (x1, y1) and (x2, y2):
numNewPoints = 100; % Whatever you want.
newx = linspace(x1, x2, numNewPoints);
y = linspace(y1, y2, numNewPoints);
coefficients = polyfit([x1,x2], [y1, y2], 1);
newY = polyval(coefficients, newx);

Hi! But how does the plot make the dots connect? Not only do I want the dots appear on the plot but also connect to the subsequent dot I obtain.

If you have data (x,y) and it's order just use plot
x = rand(1,4);
y = rand(1,4);
index = [1 4 2 3];
plot(x(index),y(index))

text: [en] Hydrothermal vent environments, particularly those associated with the vestimentiferan Riftia pachyptila, are believed to be among the highest chitin-producing systems. In order to elucidate the chitin cycle in these environments, we estimate the in situ chitin degradation rates of tube-worm exoskeletons. Our in situ experiments show that the tubes of Riftia are highly stable structures. Comparative measurements of the degradation rates of Riftia tubes and crab shells immersed at deep-sea vents show that the tubes would be degraded within 2.5 years, whereas the time for the total degradation of the vent crab (Bythograea thermydron) carapaces would not exceed 36 days. The importance of the microbial participation in this degradation was estimated for Riftia tubes. Based on previous work, we calculated chitin production by a population of Riftia tubes of about 750 g m(-2) year(-1) (763). From our in situ experiments, we estimated a microbial chitinolysis rate of about 500 g m(-2) year(-1) (496) (65% of the chitin produced). Exoskeletons containing beta-chitin appear more stable in natural environments than those containing alpha-chitin and would thus be less available as carbon and nitrogen sources. In contrast, isolated beta-chitin was hydrolysed faster than alpha-chitin during in vitro degradation experiments; for instance, Riftia beta-chitin was degraded about 3- to 4-fold faster than Bythograea alpha-chitin. A stabilization process by disulfide bonds of the proteins-chitin link, rather than the crystalline form of the chitin (alpha/beta), accounts for the resistance of Riftia tubes to enzymatic attacks.

Air Carbon Arc Cutting (CAC)
Air Carbon Arc Cutting (CAC)
Summary: Air carbon arc cutting is an arc cutting process in which metals to be
cut are melted by the heat of a carbon arc. The molten metal is removed
by a high velocity blast of compressed air. The air jet is external to the consumable carbon-graphite electrode. It strikes the molten metal immediately behind the arc.
Required equipment includes an air compressor, welding power source, carbon electrode and a gouging torch.
The air carbon arc process is shown in figure 10-75.
Comparison to Other Processes
Air carbon arc cutting and metal removal differ from plasma arc cutting in that they employ an open (unconstricted) arc, which is independent of the gas jet. The air blast physically removes metal instead of chemically, which is the approach in oxy-fuel cutting processes.
The process is more flexible than oxyfuel processes since it does not require oxidation in order to cut. The most common metals cut with the process includes cast irons, copper alloys and stainless steel. The process is widely used for back gouging, preparing joints, and removing defective weld metal.

Equipment and Circuit Diagram
The circuit diagram for air carbon arc cutting (CAC) or gouging is shown in figure 10-76.
Normally, conventional welding machines with constant current are used.
Constant voltage can be used with this process. When using a CV power
source, precautions must be taken to operate it within its rated output
of current and duty cycle. Alternating current power sources having
conventional drooping characteristics can also be used for special
applications. AC type carbon electrodes must be used.
Air Carbon Arc Cutting Diagram (CAC) - Figure 10-76
Equipment required is shown by the block diagram. Special heavy duty
high current machines have been made specifically for the air carbon arc
process. This is because of extremely high currents used for the large
size carbon electrodes.
Electrode Holder
The electrode holder is designed for the air carbon arc process (CAC).
The holder includes a small circular grip head which contains the air
jets to direct compressed air along the electrode. It also has a groove
for gripping the electrode. This head can be rotated to allow different
angles of electrode with respect to the holder. A heavy electrical lead
and an air supply hose are connected to the holder through a terminal
block. A valve is included in the holder for turning the compressed air
on and off. Holders are available in several sizes depending on the duty
cycle of the work performed, the welding current, and size of carbon
electrode used. For extra heavy duty work, water-cooled holders are
used.
Types of Electrodes
Carbon Graphite:
The carbon graphite electrodes are made of a mixture of carbon and
graphite plus a binder which is baked to produce a homogeneous
structure. Electrodes come in several types.
Plain Uncoated Electrodes:
The plain uncoated electrode is less expensive, carries less current, and starts easier.
Copper-Coated:
The copper-coated electrode provides better electrical
conductivity between it and the holder. The copper-coated electrode is
better for maintaining the original diameter during operation. It lasts
longer and carries higher current. Copper-coated electrodes are of two
types
 - DC type
 - AC type
The composition ratio of the carbon
and graphite is slightly different for these two types. The dc type is
more common.
The ac type contains special elements to stabilize the arc.
It is used for direct current electrode negative when cutting cast
irons. AC coated electrodes are made with graphite, carbon and special binder. Rare earth materials are mixed in to ensure stabilization when using alternating current.
For normal use, the electrode is operated with the electrode
positive. Electrodes range in diameter from 5/32 to 1 in. (4.0 to 25.4
mm). Electrodes are normally 12 in. (300 mm) long; however, 6 in. (150
mm) electrodes are available Copper-coated electrodes with tapered
socket joints are available for automatic operation, and allow
continuous operation.
Table 10-25 shows the electrode types and the arc current range for different sizes.
Electrode Type - Size and Current Range - Table 10-25
Polarity of Electrode is Positive (reverse polarity). Note: For DC coppered electrodes current can be increased percent.
Check Manufacturers Directions
Air Pressure
The air pressure is not critical but should range from 80 to 100 psi
(552 to 690 kPa). The volume of compressed air required ranges from as
low as 5 cu ft per min (2.5 liter per min) up to 50 cu ft per min (24
liter per min) for the largest-size carbon electrodes. A one-horsepower
compressor will supply sufficient air for smaller-size electrodes. It
will require up to a ten-horsepower compressor when using the
largest-size electrodes.
Torch
CAC Torch for Gouging
A manual carbon gouging torch is shown above. The torch holds an electrode in a swivel head that has one or multiple air holds. This way the air jet stays aligned with the electrode regardless of the electrode angle to the torch.
If the torch has two heads (air jets on both sides of the electrode) or with a fixed angle between the electrode and the holder, are better for some uses such as large castings (padwashing) or for removing pads.
The torch is cooled by air. If high-current applications are used, then water cooling can be used along with a heavy-duty torch.
Advantages and Major Uses
The air carbon arc cutting process (CAC) is used to cut metal, to gouge
out defective metal, to remove old or inferior welds, for root gouging
of full penetration welds, and to prepare grooves for welding. Air
carbon arc cutting is also used when slightly ragged edges are not
objectionable.
The area of the cut is small and, since the metal is
melted and removed quickly, the surrounding area does not reach high
temperatures. This reduces the tendency towards distortion and cracking.
The air carbon arc cutting (CAC) and gouging process is normally
manually operated. The apparatus can be mounted on a travel carriage.
This is considered machine cutting or gouging.
Special applications have
been made where cylindrical work has been placed on a lathe-like device
and rotated under the air carbon arc torch. This is machine or
automatic cutting, depending on operator involvement.
Works in All Positions:
The air carbon arc cutting process (CAC) can be used in all positions.
It can also be used for gouging in all positions. Use in the overhead
position requires a high degree of skill.
Works with Common Metals:
The air carbon arc process can be used for cutting or gouging
most of the common metals. Metals include: aluminums, copper, iron,
magnesium, and carbon and stainless steels.
The process is not recommended for weld preparation for stainless
steel, titanium, zirconium, and other similar metals without subsequent
cleaning. This cleaning, usually by grinding, must remove all of the
surface carbonized material adjacent to the cut. The process can be used
to cut these materials for scrap for remelting.
Process Principles
Principles of Air Carbon Arc Cutting Diagram
The procedure schedule for making grooves in steel is shown in table 10-26 below.
Air Carbon Arc Gouging Procedure Schedule
1. Air Pressure 80 to 100 PSI, (552 to 690 KPa) is recommended for 1/2" and 5/8" (13 and 16mm) electrodes.
2. Combination of settings and multiple passes may be used for grooves deeper than 3/4"(19mm).
To make a cut or a gouging operation, the cutter strikes an arc and
almost immediately starts the air flow. The electrode is pointed in the
direction of travel with a push angle approximately 45° with the
axis-of the groove. The speed of travel, the electrode angle, and the
electrode size and current determine the groove depth. Electrode
diameter determines the groove width.
Electrode Severing Techniques for CAC
The normal safety precautions associated with carbon arc welding and
shielded metal arc welding apply to air carbon arc cutting (CAC) and gouging.
However, two other precautions must be observed. First, the air blast
will cause the molten metal to travel a very long distance. Metal
deflection plates should be placed in front of the gouging operation.
All combustible materials should be moved away from the work area. At
high-current levels, the mass of molten metal removed is quite large and
will become a fire hazard if not properly contained.
The second factor is the high noise level. At high currents with
high air pressure a very loud noise occurs. Ear protection, ear muffs or
ear plugs should be worn by the arc cutter.

The legend says that the healing water was found by the castle's hunters. When they were hunting in the districts of Košnica and Dobrina, one of them felt sick and he was dragged along the snow towards the road to Dobrina, from where he would be taken by horses to Žusemje Castle. Amongst a large area of snow, they saw a patch of land and water which was not frozen. The sick person was given that water to drink and soon he got well.
Many other stories about the miraculous healing of people who drank that water originated later. After those legends, which represent the oldest data on the healing powers of the water in Dobrina, the name DOBRINA CASTLE SPRING originated.
The settlement of Dobrina is an excellent starting point for a walk to nearby Žusem located on the 669 m high rise where two churches stand, the first one is the Parish Church of St. Valentine, however, the second one is the 700 year old established Church of St. Jacob, which has valuable preserved frescoes from the 15th and 16th century and chandeliers made of local glass. In the nearby small village of Tinje, the archaeological finds Tinje and the remains of the sunken Žamerk Castle are located. Here, objects from the late Antique and Early Slavic period were found. In Javoršica the partisan hospital is still preserved. You can get additional information at Društvo Izviri (Springs Association).

text: In this article we present an algorithm to estimate the orientation of a robot relative to an orientation specified at the beginning of the process. This is done by computing the rotation of the robot between successive panoramic images, grabbed on the robot while it moves, using a subsymbolic method to match the images. The context of the work is Simultaneous Localization And Mapping (SLAM) in unstructured and unmodified environments. As such, very few assumptions are made about the environment and the robot's displacement. The algorithm's performance depends on the value of a number of parameters being determined to provide overall good performance of the system. The performance is evaluated in different situations (trajectories and environments) with the same parameters and the results show that the method performs adequately for its intended use. In particular, the error is shown to be drifting slowly, in fact much slower than unprocessed inertial sensors, thus only requiring infrequent realignment, for example when relocalizing in a topological map. Limitations of the proposed methods are also shown and discussed.

Strawberries and crème fraîche

Crème fraîche (English pronunciation : /ˌkrɛmˈfrɛʃ/, French pronunciation: [kʁɛm fʁɛːʃ], Quebec French pronunciation : [kʁɛm fʁaɪ̯ʃ], lit. "fresh cream") is a soured cream containing 30–45% butterfat and having a pH of around 4.5.[1] It is soured with bacterial culture, but is less sour than U.S.-style sour cream, and has a lower viscosity and a higher fat content. European labeling regulation disallows any ingredients other than cream and bacterial culture.
The name "crème fraîche" is French, but similar soured creams are found in much of northern Europe.
In French-speaking countries, crème fraîche may refer to either the thick fermented product, crème fraîche épaisse or fermentée, or to liquid cream, crème fraîche liquide or fleurette. In these countries, crème fraîche without qualification normally refers to liquid cream, with the thick form usually called crème épaisse. In other countries, however, crème fraîche without qualification usually refers to the thick, fermented product.[2][3]
Crème fraîche is produced by adding a starter culture to heavy cream, and allowing it to stand at appropriate temperature until thick.[3][2] The culture is made up of a mix of bacteria including but not limited to L. cremoris, L. lactis, and L. biovar diacetylactis. This is what gives it the taste that distinguishes it from similar dairy products like sour cream.[4]
In some places in Europe, the fat content of crème fraîche is regulated, and it may not contain ingredients other than cream and starter culture.[1] In North America and the UK, products labeled "low-fat crème fraîche", with about 15% butterfat and with added stabilizers such as xanthan gum or maize/corn starch[5] is commercialized. It is less stable when heated.[3]

The crème fraîche from Normandy is famous, and the crème fraîche from a defined area around the town of Isigny-sur-Mer in the Calvados department of Normandy is highly regarded. It is the only cream to have an appellation d'origine contrôlée (AOC), which was awarded in 1986.[6] It is also produced in many other parts of France, with large quantities coming from the major dairy regions of Brittany, Poitou-Charente, Lorraine and Champagne-Ardenne.
Crème fraîche is used both hot and cold in French cuisine. It is often used to finish hot savory sauces; with fat content > 30%, curdling is not a problem.[1] It is also the basis of many desserts and dessert sauces.
Similar products[edit]
Crema Mexicana is a somewhat similar cultured sour cream.

C vs Rust cyber security programming. Which one to choose.
C vs Rust cyber security programming. Which one to choose.
·
2 min read
Both C and Rust are programming languages that can be challenging to learn, especially if you are new to programming. However, they are both powerful languages that are widely used in the software industry.
To create a simple Fibonacci sequence in C, you could use the following code:
#include <stdio.h>
int main() {
 int i, n, t1 = 0, t2 = 1, nextTerm;
 printf("Enter the number of terms: ");
 scanf("%d", &n);
 printf("Fibonacci Series: ");
 for (i = 1; i <= n; ++i) {
 printf("%d, ", t1);
 nextTerm = t1 + t2;
 t1 = t2;
 t2 = nextTerm;
 }
 return 0;
}
To create a simple Fibonacci sequence in Rust, you could use the following code:
fn main() {
 let mut t1 = 0;
 let mut t2 = 1;
 let mut next_term;
 let n = 10;
 println!("Fibonacci Series: ");
 for _ in 0..n {
 next_term = t1 + t2;
 t1 = t2;
 t2 = next_term;
 println!("{}", t1);
 }
}
It is difficult to determine which version of the code will be faster without profiling them and comparing the performance. In general, C is known for being a fast and efficient language, while Rust is designed to provide the performance of a systems language while being safer and easier to use.
It is difficult to determine which of the two languages, C or Rust, is the "best" to use in cybersecurity based on the simple Fibonacci sequence examples provided. Both C and Rust are powerful languages that are used in a variety of applications, including in the field of cybersecurity.
In the field of cybersecurity, either C or Rust could be a good choice, depending on your specific needs and goals. Both languages have their own strengths and limitations, and the best choice for your project will depend on the requirements and constraints of your project.
In general, if you are new to programming and are looking for a language that is easier to learn and use, Rust may be a better choice for you. On the other hand, if you have experience with C or other low-level languages and are comfortable with the complexity and challenges of systems programming, C may be a better choice. Ultimately, the best language for your project will depend on your specific goals and requirements.
As you can see all languages can run the same code but different syntax. All compiled, and fast.

In this challenge, we are going to look at Extensible Stylesheet Language (XSL) and how it can be used to trigger unexpected behaviors in applications leveraging them, specifically in a Java application. To solve this challenge, you will need to gain command execution. This involves leveraging the 'xsl:variable' tag to access the current 'Runtime', which will allow you to call the method 'exec' with the desired command.
The process starts with uploading an XSL file to transform the given XML. By creating an object from 'rt:getRuntime()', you can get the current runtime. Using this runtime object, you can call 'exec' with your command. This method is effectively demonstrated in the video, where the command is replaced with the score command, uploaded, and executed, ultimately solving the challenge.

In order to use the BrokenRules object within our Person object, we need to declare and create a Private variable to hold the new object. Add the following line of code to the General Declarations section of our Person class module:
Private WithEvents objValid As BrokenRules
We also need to add code in the Person object's Class_Initialize routine to create an object for this variable:
Private Sub Class_Initialize()
Set objValid = New BrokenRules
objValid.RuleBroken "SSN", True
End Sub
Notice, here, that we're forcing the "SSN" rule to be considered broken straight away. This is important, because, as the programmer, we know that the value is blank to begin with, so we need to make sure the business rule is enforced right from the start by indicating that it's broken.
An important note about events. An object can't raise events until it has been fully instantiated, and an object isn't instantiated until after the Class_Initialize routine is complete. This means that any RaiseEvent statements called during the Class_Initialize routine won't actually raise any events – which is what we'd really like to have happen.
In this example, we're indicating that a rule is broken, so the BrokenRule event should fire; but it won't, because we're still in the Class_Initialize routine.
Handling the BrokenRule and NoBrokenRules Events
Our Person object needs to handle the events that will be created by the BrokenRules object we just created. To make it easier for the UI developer, we'll also have our Person object raise an event to let the UI know when the Person object becomes valid or invalid.
This first line that we'll add to handle these events goes in the General Declarations section of the Person class module, and it declares the Valid event. We'll use this event to indicate when our Person object switches between being valid and invalid:
Event Valid(IsValid As Boolean)
As we've seen, our BrokenRules object raises two events of its own: BrokenRule and NoBrokenRules. The BrokenRule event will be fired whenever a new rule is broken, while the NoBrokenRules will be fired any time the number of broken rules reaches zero.
By adding the following code to our Person object, we'll be able to react to these events by raising our own Valid event to tell the UI whether the Person object is currently valid:
Private Sub objValid_BrokenRule()
RaiseEvent Valid(False)
End Sub
Private Sub objValid_NoBrokenRules()
RaiseEvent Valid(True)
End Sub
If the BrokenRule event is fired then we know that at least one of our Person object's rules is broken. We can then raise our Valid event with a False parameter to indicate to the UI that the Person object is currently invalid. Likewise, when we receive a NoBrokenRules event, we can raise our Valid event with a True parameter to indicate to the UI that there are no broken rules and that our Person object is currently valid.
Implementing the IsValid Property
When we started this discussion, it was with the intent of creating an IsValid property on our Person object so that the UI could check to see if the object was valid at any given point. By implementing the Valid event in the previous section, we've actually provided a better solution; but we can't assume that the UI can actually receive events, since not all development tools provide support for them. The IsValid property therefore remains very important.
Fortunately, our BrokenRules object makes implementation of the IsValid property very trivial. The BrokenRules object provides us with a count of the number of broken rules, and if that count is zero then we know that there are no rules broken. No broken business rules translates very nicely into a valid Person object.
To implement our IsValid property, let's enter the following code into the Person class module:
Public Property Get IsValid() As Boolean
IsValid = (objValid.Count = 0)
End Property
This property simply returns a Boolean value that's based on whether the broken rule count equals zero or not.
Enforcing the SSN Business Rules
In our Person object's Class_Initialize routine, we added a line to indicate that our SSN field was invalid. Since we're making it a required field, and all fields in a brand new object are blank, we know that the rule is broken during the initialization of the class.
We can therefore finish the job by adding some code to check our business rules within the Person object's Property Let routine for our SSN property:
Public Property Let SSN(Value As String)
If Len(Value) > 11 Then _Err.Raise vbObjectError + 1001, "Person", "SSN too long"
udtPerson.SSN = Value
objValid.RuleBroken "SSN", (Len(Trim$(udtPerson.SSN)) <> 11)
End Property
What we've done, here, is simply call the RuleBroken method of our BrokenRules object, passing it the name of our rule "SSN" and a Boolean to indicate whether the rule is currently broken. In this case, the rule just checks to make sure the value is exactly 11 characters long.
Anywhere that we need to enforce a rule in our object, we just need to add a single line of code with the rule's name and a Boolean to indicate if it's broken or unbroken. All the other details are handled through the BrokenRules object and the events that it fires.
Using the Valid Event and IsValid Property in the UI
At this point, we've implemented the BrokenRules object to keep track of how many business rules are broken within a business object. We've also enhanced our business object, Person, to take advantage of the new BrokenRules object. All that remains is to enhance our user interface to take advantage of the Valid event and IsValid property that we just added to our Person object.
A rich user-interface should be able to enable or disable the OK and Apply buttons as appropriate, so that they're only available to the user if the object is actually valid at the time. Most users dislike clicking on a button only to be told that the requested operation can't be performed. Ideally, when an operation can't be performed, the associated buttons should be disabled.
In our case, the OK and Apply buttons are only valid if the business object itself is valid. If the business object isn't valid then we can't save it, so both the OK and the Apply button should be disabled.
Adding the EnableOK Subroutine
The easiest way to manage the enabling and disabling of these buttons is to put the code in a central routine in the form. In our case, we'll need to add the following routine to our EditPerson form in the PersonDemo project:
Private Sub EnableOK(IsOK As Boolean)
cmdOK.Enabled = IsOK
cmdApply.Enabled = IsOK
End Sub
Using the IsValid Property
When the Edit Person form loads, the first thing it needs to do is make sure that the buttons are enabled properly. We need to check the Person object's IsValid property in our Form_Load routine to find out if the business object is valid at this point. Add this line of code to the EditPerson form's Form_Load routine:
Private Sub Form_Load()
Set objPerson = New Person
EnableOK objPerson.IsValid
End Sub
All we need to do is call our EnableOK subroutine, passing the Person object's IsValid property value as a parameter. If the object is valid, we'll be passing a True value, which will indicate that the OK and Apply buttons are to be enabled.
It might look as if we could rely on the Person object's Valid event to fire as the object was created. We could then act on that event to enable or disable the two buttons on our form. Unfortunately, objects can't raise events as they are being created, so there is no way for our Person object to raise its Valid event while it's starting up. This means we can't rely on the Valid event to tell us whether the object is valid as our form is first loading.
Responding to the Valid Event
Once the EditPerson form is loaded and the user is interacting with it, we can rely on the Person object to raise its Valid event to tell the form whether it is currently valid. In our EditPerson form, we can add code to respond to this event, enabling and disabling the OK and Apply buttons as appropriate:
Private Sub objPerson_Valid(IsValid As Boolean)
EnableOK IsValid
End Sub
Since the object will raise this event any time it changes from valid to invalid or back, the UI developer can rely on this event to enable or disable the buttons for the life of the form. All we need to do is call our EnableOK subroutine, passing the IsValid parameter value to EnableOK to indicate whether to enable or disable the two buttons.
Removing the SSN Change Event Code
As our form currently stands, we have code in the Change event of the txtSSN control to trap any error raised by our business object. Now that we've enhanced the business object to utilize the BrokenRules

Gondor's Golden Age during the time of Hyarmendacil I.
The Ship-kings was a title given to four great Kings of Gondor during its "golden age", starting with King Tarannon Falastur, and his three successors:
Their influence was such that, at the end of the reign of Hyarmendacil I, Gondor had reached a peak of strength and power that it would never again surpass. Indeed, the period of the ship-kings was followed by a period of stagnation, disasters and wars, that led to its decline.[1]

Make a cheap, high-tech nozzle to eliminate turbulence and create incredible water effects.
By Larry Cotton and Phil Bowie
Laminar-flow water charms and fascinates. It behaves quite differently from ordinary turbulent water, such as the flow from a faucet or garden hose. A laminar stream is so perfect it could pass for a glass rod. It doesn't splash upon hitting a surface, it will conduct light like a fiber-optic cable, and it's so cohesive, it will enwrap and levitate a smooth sphere, even at a surprising angle to the vertical.
In 2011, we drove 600 miles from our North Carolina homes to Disney's Epcot theme park to study the "Leap Frog" fountain, which chops a laminar stream into arcs, creating impish, cavorting water creatures. We've been obsessed with laminar flow phenomena ever since, joining an online cult of experimenters.
We have achieved laminar flow simply and inexpensively by making a nozzle from a big plastic peanut butter jar, scrub pads, drinking straws, and standard PVC pipe and hose fittings. A fine way to show off its elegant stream is to build a fountain using this nozzle as its heart. It's easy to make, and can produce captivating shapes or even levitate lightweight spheres.

On this day: Attack on the 405 bus
July 6 1989: Terror on the road to Jerusalem
Fourteen people were killed in an incident that has since been described as the first suicide attack on Israelis.
The attack, which also left 27 people with injuries, occurred on the number 405 bus from Tel Aviv to Jerusalem. The driver had reached the junction after the Israeli Arab village of Abu Ghosh, when a man seized the steering wheel and began shouting in Arabic.
He pulled the bus to the right and, despite a struggle with the driver, succeeded in making it go over the side of a cliff.
Among those killed were a Canadian schoolgirl and a 15-year-old from Jerusalem, whose father had been injured in a petrol bomb ten years earlier. The perpetrator was later identified as a 25-year-old Arab from a refugee camp. He was hospitalised and subsequently convicted of murder, hijacking and terrorism.
What happened prompted immense anger in Israel, with a number of retaliatory incidents, which Prime Minister Yitzhak Shamir condemned as a "worrying phenomenon".
President Chaim Herzog said of the attack: "This tragic incident reminds that the fight against terror in our country has not ended."
The attack had another lasting impact – it prompted the creation of Israel's Orthodox disaster response organisation ZAKA, after yeshiva student Meshi Zahav was one of the first on the bloody scene. He later said of what he saw that it was "chilling and horrifying chaos".
What the JC said: The bus had just begun picking up speed on the long, straight stretch of the road after the junction at the Arab village of Abu Ghosh [which sided with Israel in the War of Independence in 1948], when an Arab passenger went up to the driver and wrenched the steering wheel to the right, sending the bus careering into a ravine. As the bus rolled over, finishing up on its roof and catching fire, most of the passengers were thrown out.

the IBM Z JCL Expert plug-in for Zowe CLI and there is no limit on how much automation you can achieve leveraging this plugin. As mentioned at the beginning, the power of the Zowe CLI is not just the individual commands but the ability to write scripts (in the scripting language of your choice) to build multi-step actions to integrate IBM Z JCL Expert in your automated process or any other product with Zowe CLI extensions. These scripts can have variable substitution, use additional script functions (grep, awk, etc.) to build powerful productivity tools.
A common example can be to run a JCL Check before submitting a job.
In a recent blog I described a scenario that leverage the IBM Z Workload Scheduler plugin for Zowe CLI to add a jobstream in plan and submit it for execution. In that scenario, the second job of the jobstream was ending in error … because of an error in the JCL itself. This is the JCL used in that scenario:
Leveraging IBM Z JCL Expert to check this JCL, I would have intercepted the problem before the execution of the job:
On the other hand, I envision even the possibility to have application developers that use it in an interactive way, to avoid logging onto TSO just to change and check a specific JCL. Ultimately, different users will use the plug-in in different ways. The Zowe CLI can have scripts that cross z/OS products and systems to allow coordination of actions in many ways.
An important point to make is that customers that leverage IBM Z JCL Expert, get IBM Z Distribution for Zowe as supporting program, so the support (for the scenarios that are related to the integration) is granted from IBM at no charge. This is important because many enterprises do not allow unsupported software in their production environment.
If you want to learn more about IBM Z Distribution for Zowe, visit the content page, you can find there other details about IBM product extensions and more.
If you want to download the IBM Z Z JCL Expert technical preview of the plug-in for the Zowe CLI, it is available here.

Let $M$ be a geometrically finite hyperbolic surface with one cuspidal end and one funnel end so that it can be divided into $C \cup K \cup F$ where $C$ is the cusp, $F$ the funnel and $K$ the compact core.
Focus on the cusp with the following boundary defining function (due to David Borthwick: Spectral Theory of Infinite-Area Hyperbolic Surfaces)
Let $\rho (x)=e^{-r}$ where $r$ is the distance of $x$ to the compact core $K$. As a boundary defining function it needs to have a non-vanishing differential on the boundary. How can this fact be seen for this function?
If I take the look back to the upper half plane the hyperbolic distance for distinct points $a$ and $b$ located on the y-axis is given by $log(a/b)$. I suppose that's the reason for choosing $e^{-r}$. If you take a point $c$ at the boundary its distance to the compact core is infinite, so $e^{-r(c)}$ is zero, clearly. But what's with the differential? Is there a direct way of calculating it in this case with the given information? I don't understand why is it not zero at the boundary.
In a discussion with others there was the idea to show it by relating the the boundary defining function for the cusp to a (maybe given) boundary defining function for a funnel end by 'inverting', precisely:
Here $M = (0, \infty) \times S^1$ with the metric $g=(dx^2+d\theta^2)/x^2$ where the variable $x$ refers to $(0,\infty)$ and $x$ itself is a boundary defining for the funnel end. If $x$ is bdf for the funnel, is it true that then 1/x is a boundary defining function for the cusp?
My problem is the absence of a diffeomorphism from the cusp (as a point) to the funnel (which is a circle). Can this be repaired by viewing the cusp as a 'infinitely' small circle? The strategy I have in mind is: If there would be a diffeomorphism between the ends and given a boundary defining function for the funnel then the pullback of it has non-vanishing differential.
Since this is my first question on MO, I hope my explanations were precise enough and the questions aren't too basic.
Thank you for your help, Robin Neumann

How to Install OpenOffice on Linux
Written in C language, Apache OpenOffice is a powerful software suite that allows you to perform basic office tasks such as word processing, create spreadsheets, and create stunning presentations. Written in C language, OpenOffice is opensource and free to download. It closely resembles the LibreOffice suite and is considered an ideal alternative to the Microsoft Office suite.
In this article, you will know how to install Openoffice on Linux Distributions such as Ubuntu, Debian, Mint, RHEL, and CentOS.
At the time of penning down this guide, the latest version of OpenOffice is Openoffice 4.1.7. Apache OpenOffice comes bundled with the following applications:
 1. Calc - A spreadsheet application, the equivalent of Microsoft Excel.
 2. Impress - This is a simple yet effective tool for creating slide presentations.
 3. Writer - A word processing application, the equivalent of Microsoft Word.
 4. Draw - A nifty tool that allows you to draw 3D images and create simple diagrams.
 5. Base - A database tool that lets you design tables, forms as well as create queries to retrieve results from the tables.
 6. Math - A tool that enables you to come up with mathematical equations.
That said, let's now switch gears and see how you can install OpenOffice on various Linux distributions.
How to install OpenOffice in Ubuntu/Debian/Mint
Firstly, before you embark on the installation of OpenOffice, ensure that Java is installed on your system. To do this, run the command:
$ java -version
If Java is not installed, you will the following output printed on your terminal:
Command 'java' not found, but can be installed with:
sudo apt install default-jre # version 2:1.11-72, or
sudo apt install openjdk-11-jre-headless # version 11.0.7+10-3ubuntu1
sudo apt install openjdk-13-jre-headless # version 13.0.3+3-1ubuntu2
sudo apt install openjdk-14-jre-headless # version 14.0.1+7-1ubuntu1
sudo apt install openjdk-8-jre-headless # version 8u252-b09-1ubuntu
To install Java, run the following command to install the default Java Runtime Environment (JRE) . This installed JRE from OpenJDK 11.
$ sudo apt install default-jre
Next, uninstall or remove the LibreOffice suite and its associated packages. To accomplish this, run the command:
$ sudo apt-get remove --purge libreoffice*
Next, clear the cache and free up the disk space.
$ sudo apt clean
$ sudo apt autoremove
Next, head over to the Official download page and select to download the Debian package from the pull-down menu shown.
download OpenOffice Debian package install OpenOffice on Linux
Similarly, you can run the following command on the terminal to download the Debian package.
$ wget _URL_
Now you have to extract the downloaded the tarball file:
$ tar -xvf Apache_OpenOffice_4.1.7_Linux_x86-64_install-deb_en-US.tar.gz
Once extracted, you will end up with a folder called en-US with a subfolder called DEBS that contains all the Debian packages that need to be installed. Therefore navigate to this sub-folder.
$ cd en-US/DEBS
Next, install OpenOffice using the following command as shown:
$ sudo dpkg -i *.deb
Finally, set up the desktop integration feature for your installation by navigating to the desktop-integrations directory
$ cd desktop-integrations
To install the desktop integrations feature, run the command:
$ sudo dpkg -i *.deb
How to install OpenOffice in CentOS/RHEL/Fedora
The installation of OpenOffice in CentOS & RHEL is pretty much similar to the installation of OpenOffice on Ubuntu and Debian distros. After uninstalling LibreOffice, head out to the OpenOffice download page and select to download the RPM package.
Download RPM package OpenOffice
Or you can download the package on the terminal for the specific version:
$ wget _URL_
Next, proceed and extract the tarball file.
$ tar -xvf Apache_OpenOffice_4.1.7_Linux_x86-64_install-rpm_en-US.tar.gz
This yields a en-US directory in your current working directory with the RPMS sub-directory that contains all the RPM packages associated with OpenOffice.
Navigate to 'en-US/RPMS' sub-directory.
$ cd en-US/RPMS
Install OpenOffice as shown:
$ sudo rpm -ivh *.rpm
The last step involves setting up the desktop integration for your OpenOffice setup. There's a desktop-integration directory in the RPMS directory. Navigate into it.
$ cd desktop-integration
Finally, execute the command:
$ sudo rpm -i openoffice4.1.7-redhat-menus-4.1.7-9800.noarch.rpm
Lanching OpenOffice
Once OpenOffice is installed, Launching it is quite easy. You can do it either via the terminal or using the application menu. On the terminal, run the command:
$ openoffice4
If you are using the application menu, simply search for the keyword 'OpenOffice'.
Launching OpenOffice suite
Next, click on the installation icon which is second from the left:
OpenOffice installation icon
This will open the welcome page as shown. Click on the 'Next' button to proceed.
OpenOffice welcome page
In the next step, fill out your username and provide the initials. Then finally click on the 'Finish' button
Provide username OpenOffice setup
Apache OpenOffice will start initializing and loading its components for the first time.
Install OpenOffice on Linux
Next, select the software application that you'd like to launch from the list of applications that bundle with Apache OpenOffice.
Install OpenOffice on Linux
Conclusion
In this article, we have shown you how to install OpenOffice on Linux.

Backyard hose water playThere's nothing better than running around in the back garden with a hose (or a bucket of water if there's water restrictions) on a hot day! Hours can be happily spent dreaming up watery games.
What You Need:
- Garden hose
There are many ways kids can have fun with a garden hose and a bucket:
- Go around the backyard watering the plants.
- Have a water fight game using buckets of water.
- Use a stream of water to play a game of limbo (by going under the stream) or high jump ( by jumping over the stream)
- Use the stream of water for target practice. Use chalk to draw a bulls eye and then try and hit the bulls eye with water.
- Build a dam in a garden bed.

DML Settings in Component
Hello,
Can someone please clarify me what is the exact difference between
propagate from neighbor and propagate through in the DML tab?
At times, I see both of them behave in the same way.
When to use which one? And what's the difference in their usage?

Thanks,
Sarkos

Propagate from neighbor specifies that the port will take it's DML from the port to which it is connected.
Propagate through specifies that the input DML will be used as the output DML.
Please see the Ab Initio documentation helpfile section:
GDE Help > Working with graphs and plans > Creating graphs and plans > Setting layout and record format propagation
Some components do not permit the output port DML to be different than the input port. The SORT component must output the same record format as its input.
Other components such as ROLLUP almost always have differing input and output DML record formats.
A component like REFORMAT might or might not have different input and output DML record formats.

Hi,
I would like to add some add some points here:
*propagate from neighbor*-its always take DML from the component that is
connected to its input port.it can not take DMl from the component
that is connected to it's output port.
It can not be chosen, when you are embedding the DML directly in the
component( eg sometime as in reformat.)
When you are giving DML,path, then you would find it out that
"propagate through" is disabled but "propagate from neighbor" is
enabled even then.
For some component you can not choose *propagate from neighbor-eg
Normalize,input file,*
*Propagate through in the DML tab*--- is useful for writing the DML in
output port

*Mantosh Kumar Dubey*

What is the difference between 304 and 316 stainless steel？
Out of over 60 different grades of stainless steel, the most often used in the electrical industry are 304 stainless steel and 316 stainless steel
Aesthetically, there is no difference between the two; in fact, the only way to differentiate between them is to test them chemically. The main difference between 304 and 316 stainless steel is 316 SS has the addition of molybdenum.
The differing chemical makeups of 304 SS and 316 SS influence how each performs in a certain environment. Requirements for one grade of stainless over the other are often dependent on the application or environment; therefore, it is important to understand them both.
Description and application of 304 stainless steel
Type 304 SS is the most widely used grade of stainless steel and is considered the standard "18/8" stainless. It offers mechanical strength, corrosion, and oxidation resistance at a more economical price point.
Type 304 SS is used in a wide range of applications and industries to provide basic resistance to corrosion.
Description and application of 316 stainless steel
Type 316 SS is more corrosion resistant than 304 SS because of its higher nickel content and the addition of molybdenum (2-3%) as an alloying element. The addition of molybdenum enhances the metal's resistance to crevice corrosion and pitting from chloride solutions. The overall combination of increased nickel, molybdenum and other minor alloying tweaks improves the resistance of 316 SS to stress corrosion cracking, creeping, chemicals, solvents, sulfuric acids, and extreme temperatures.
This makes 316 SS an ideal choice for electrical products subjected to industrial processing chemicals, ocean spray, or high-chloride environments.

Real structures of models of arrangements. (English) Zbl 1076.52005
The author continues previous work, constructing and studying models of real subspace arrangements. Like the models of De Concini and Procesi for complex subspace arrangements, these are constructed in order to obtain information about invariants of the complement of the union of the subspaces. They are derived from combinatorial structures, called "building sets", obtained from a finite partially ordered set of subspaces which is determined by the arrangement. There are usually many building sets associated with an arrangement, each giving rise to a model. This paper studies two real structures associated with the model. The first is essentially the real part of the De Concini-Procesi complex model. The second, which arises when the arrangement is a Coxeter arrangement, is an "extension" of the model to a convex set, the face lattice of which generalizes in a way the "Kapranov permutoassociahedron".

The City has a water supply capacity of 7.6 million gallons per day. This water is pumped from city-owned wells, drawing from the deepest and purist aquifers. Currently the City only pumps an average of 2 million gallons per day, with the peak usage going up to almost 4 million gallons per day in the summer. The City has five (5) elevated water tanks and certain wells have back up generation, or motors, to be able to pump water during power outages.
Water Main Break at King's Rd
A significant portion of the City of Niles' water distribution system was installed more than 50 years ago. Water reliability studies are completed from time to time so that the Utilities Department can plan for water system infrastructure improvements. Major improvements have been completed which increase the quality of the water as well as the efficiency of the water system. Included in these capital improvements were the construction of an iron filtration plant, establishment of an intermediate water pressure district on the east side of town, and the addition of water storage in the Bertrand Township Industrial Park. This water system improvement program was completed at a cost of $5.8 million. The City issued general obligation bonds to raise the funds to complete this capital improvement program. The money to support these capital improvements will come from rate increases administered over a ten (10) year period.Water Rates (effective October 1, 2020)

MicroKernel Router Status Codes
This section lists the status codes you can receive from the MicroKernel router, which receives requests from the Btrieve requesters and routes them to the correct version of the MicroKernel.
3000: The MicroKernel router encountered a memory allocation error
The MicroKernel router could not internally allocate memory. Check the Pervasive Event Log (PVSW.LOG) for more information.
3001: Local access is unavailable to the MicroKernel router
A call to the MicroKernel failed. This is most likely the result of an incorrect configuration. For example, if the MicroKernel is unavailable because of configuration settings and the file to be opened is local, then the MicroKernel router returns this status code.
3002: The MicroKernel router resource DLL is unavailable
The MicroKernel resource DLL is either missing or incompatible with the current version of the router. If this happens, the MicroKernel reverts to its default settings and continues to run. Check the Pervasive Event Log (PVSW.LOG) for more information.
3003: The MicroKernel router detected an incompatible network component
The networking services component is not compatible with this version of the MicroKernel router. The most likely cause is that the Networking services DLL has been replaced by an older version. Check the Pervasive Event Log (PVSW.LOG) for more information.
3004: The MicroKernel is not responding to the MicroKernel router
The MicroKernel is not responding to requests from the MicroKernel router. Verify that the MicroKernel is running.
3005: The MicroKernel router encountered an operating system error
The MicroKernel router encountered an unexpected error from the operating system, such as a shared memory failure. Check the Pervasive Event Log (PVSW.LOG) for more information.
3006: The MicroKernel router detected an invalid session
The session information contained in a position block is invalid. This status code occurs for one of the following reasons:
- The application is trying to use a position block for a file that resides on an engine and for which the connection has been previously terminated via a B_STOP (25) or B_RESET (28) operation.
- The application is trying to use a position block for a file that resides on a remote server and that encountered an abnormal network error on a previous operation.
- When using only the NetBIOS protocol with a remote Workgroup engine, the client is sending more bytes than can fit into the engine's network read buffer. Go the machine where the remote Workgroup engine is installed, and try increasing the value of the configuration parameter, Server4Communication Buffer Size4Read Buffer Size.
3008: Invalid configuration for MicroKernel router
This status code results from an invalid configuration. For example, if both client configuration options, Access4Use Local MicroKernel Engine and Access4Use Remote MicroKernel Engine are set to Off, the router has no valid path to take. If this situation occurs, set at least one of these options to On, depending on whether you are using a local engine, a remote Server engine, or both.
3009: NETinterface.DLL is not loaded
The MicroKernel router could not find NETAPI.DLL.
3012: Local engine is not accessible to the MicroKernel router
Access to the local engine is not possible because it is not loaded or could not be launched. You can receive this status code if you try to access a local file on a client and you do not have a Workgroup engine installed or if you try to access a local file on a server and the Server engine is not running.
If you have only a server engine installed and your Pervasive Event Log (PVSW.LOG) contains Status Code 3012 warning entries, perform the following steps:
To Turn Off Local Engine support (for clients and workstations only):
- Start Pervasive PSQL Control Center (see "Starting PCC on Windows" on page 3-3 in Pervasive PSQL User's Guide).
- Expand Local Client. Right-click MicroKernel Router and select Properties. Login if prompted.
- Click Access.
- In the right hand frame, change the value of Use Local MicroKernel Engine to Off.
- In the right-hand frame, change the value of Use Remote MicroKernel Engine to On. Click OK.
- Restart the engines for the new settings to take effect.
3013: The remote engine is inaccessible to the MicroKernel router because the networking component is not loaded
Access to the remote engine is not possible because the MicroKernel router could not initialize the networking component. Possible causes include:
- The client configuration option, Access4Use Remote MicroKernel Engine, is incorrectly set to Off. Set it to On to access a remote Server engine.
- The required networking component could not be found or is not compatible.
3014: The MicroKernel router cannot find an engine
The MicroKernel router could not complete the operation because it did not find an engine (local or remote) that could process the operation. Possible causes include:
- The target network operating system is not available.
- The target engine is not available.
- In a Windows 3.x environment, you are using a shared drive name that contains a space. To resolve the condition, remove the space from the shared drive name. For example, if you connect to a server named "D Drive", change the share name to "D_Drive".
3015: The MicroKernel router encountered an initialization error
An unexpected error occurred during the initialization of the MicroKernel router. Check the Pervasive Event Log (PVSW.LOG) for more information.
3016: The MicroKernel router encountered an internal error
The MicroKernel router encountered an internal error. Check the Pervasive Event Log (PVSW.LOG) for more information.
3017: Data buffer of the local engine is too small
The requester has more data to send the MicroKernel than the MicroKernel buffers can handle. This status code is only relevant to an engine running locally and does not apply to client/server environments. Some possible solutions include:
- Specify higher values for Communications Buffer Size (see "Configuration Reference" on page 4-1 in Advanced Operations Guide.
- Use smaller buffers in your operations.
3018: The file is already closed
The MicroKernel router is shut down and is not accepting any more requests.
3019: The MicroKernel router encountered a semaphore error
A semaphore error occurred while trying to establish contact with the local engine. Check the Pervasive Event Log (PVSW.LOG) for more information.
3020: An error occurred while loading the MicroKernel
You receive this status code when an error occurs while loading the MicroKernel or when access to the server and client machine shared memory objects are unavailable. Check the Pervasive Event Log (PVSW.LOG) for more information.
3021: The MicroKernel router received a badly formatted data packet
The MicroKernel router rejected the response from the engine because it was badly formatted.Check the Pervasive Event Log (PVSW.LOG) for more information.
3022: The MicroKernel router could not send the request to the remote engine because the specified data buffer length resulted in a data packet object that is too large
A request to the MicroKernel router specified a data buffer length that resulted in a data packet size greater than 64 KB, which is the maximum. This can occur even if the data buffer length for the request is smaller than 64 KB because the MicroKernel router adds some packet overhead as it forms the data packet. Check the Pervasive Event Log (PVSW.LOG) for more information.
3030: Remote access not allowed
This code is returned if the path is remote, the client configuration setting for Use Local MicroKernel Engine has been set to Off, and either:
- the key number on the open request indicates 'local only'; OR
- the configuration setting for Use Remote MicroKernel Engine is set to Off.
3031: Linux requester cannot connect to this server
This code is returned if a Pervasive PSQL Linux requester attempts to connect to a Pervasive.SQL 2000 server that has Service Pack 2a or earlier, or a Pervasive.SQL V8 server without Service Pack 1.
- To use the Linux requester to connect to a Pervasive.SQL 2000 server, you must have a special update that is available at _URL_
- To use the Linux requester to connect to a Pervasive.SQL V8 server, you must have Service Pack 1 or higher which is available for download at _URL_
3032: Failed to initialize shared memory to local engine
This status code results if a second user attempts to access another user's database engine through the transactional interface. The application is unable to connect to the local engine. Possibly a database engine has been started by another user on the machine in a non-elevated mode. If so, other users will not be able to connect to that engine.
One situation in which this status code may result is if a user starts the Workgroup Engine or Cache Engine in a Terminal Services session or by switching users through fast-user switching. Other users on the system cannot access that engine nor can they start their own copy of the engine. To allow multiple users access to a Workgroup Engine or Cache Engine in a Terminal Services session or through fast-user switching, start that engine as a service instead of as an executable.

What is legal medicine?
Legal medicine encompasses a wide range of professionals in both health and law who aim to bridge the gap between law and medicine. A medical or legal professional might choose to associate themselves with the American College of Legal Medicine
(ACLM), becoming a part of the organization in order to further their career, network with other professionals, or contribute to the field.
The ACLM also represents the specialty of legal medicine in the American Medical Association's Specialty and Service Society.
As a branch of medicine, it deals with the application of medical knowledge to the law; doctors who choose to work in legal medicine weigh in on legal proceedings, legal problems or legislation involving medical information that requires a medical expert. Some doctors aim to improve health policy, health care, promote research and scholarship, or promote peer collaboration and interaction. Some doctors in the field also have a law degree.
Legal medicine is also frequently called forensic medicine; legal medicine physicians are known by many different titles depending on the duties of their position, such as medical jurist, medical examiner, medico-legal officer, medico-legal expert, death investigators, and other titles. There may be cross-over of titles depending on the organization, company, medical practice, or area where the doctor works. For example, a physician and a lawyer working in the same field and with identical interests are sometimes referred to by different titles, despite the similarities between their jobs. A physician may be involved in forensic medicine, while a lawyer with the same interests working in forensic medicine is said to work in medical jurisprudence.
If you're seeking a physician or other expert who specializes in legal medicine, consider contacting the ACLM
for any needs that may involve: litigation, expert witnesses, medico-legal guidance or forensic medicine.What are some of the ways a medical examiner might contribute to a court case?
A medical examiner observes victims' bodies to determine the cause, manner and time of death. A thorough investigation of wounds helps the doctor reconstruct how a death occurred, which in turn helps lawyers determine how to present evidence in court. These doctors perform autopsies to determine cause of death, either as required by court, police officers, or by written request of nearest kin.
A medical examiner may testify in court and report some (or all) of the following facts:
- Identification of blood and blood stains, age of blood stains, age of victim
- The cause, manner and time of death
- Tissue changes in the body as correlated to criminal acts


Currently, I am developing an octree data structure. And I need it to be fast. To this end, I would like to have a fast way to extract the $m$ binary digits "after the dot" of each entry in a matrix of machine precision numbers. This matrix is of size $n \times d$ where $d$ is the space dimension (say $d=3$) and represents a set of $n$ points (shift and rescaled to lie in the unit box) to which the octree has to adapt. The number $n$ is typically in the range of a couple of 100 thousands and a few million. So, the input parameters are, e.g.,
n = _PHONE_;
d = 3;
m = 32;
x = RandomReal[{0., 1. - $MachineEpsilon}, {n, d}];
For performance, it is crucial that the resulting $n \times d \times m$ tensor is a packed array of Integers. As you can see below, I have tried already several things. But in view of the fact that actually nothing has to be computed as the mantissas of the machine precision numbers are actually stored in binary, the timings are really disappointing.
ToPack = Developer'ToPackedArray;
cf = Compile[{{z0, _Integer}, {base, _Integer}, {n, _Integer}},
 IntegerDigits[z0, base, n],
 CompilationTarget -> "C",
 RuntimeAttributes -> {Listable},
 Parallelization -> True,
 RuntimeOptions -> "Speed"
digits1 = ToPack[RealDigits[x, 2, m, -1][[All, All, 1]]]; //
 AbsoluteTiming // First
digits2 = ToPack[IntegerDigits[IntegerPart[x 2.^m], 2, m]]; //
 AbsoluteTiming // First
digits3 = Transpose[Table[Mod[IntegerPart[x 2.^k], 2], {k, 1, m}], {3, 1, 2}]; //
 AbsoluteTiming // First
digits4 = Transpose[cf[IntegerPart[x 2.^m], 2, m], {1, 2, 3}]; //
 AbsoluteTiming // First
digits1 == digits2 == digits3 == digits4
I have also tried to use BitGet but that was a couple of times slower than RealDigits.
In practice, I do not know in advance how many digits I need. So it would be even better to retrieve only the $k$-th digit at a time. In this case, the timings look as follows:
k = 4;
digit1 = ToPack[RealDigits[x, 2, 1, -k][[All, All, 1, -1]]]; //
 AbsoluteTiming // First
digit2 = ToPack[
 IntegerDigits[IntegerPart[x 2.^k], 2, 1][[All, All, -1]]]; //
 AbsoluteTiming // First
digit3 = Mod[IntegerPart[x 2.^k], 2]; // AbsoluteTiming // First
digit4 = cf[IntegerPart[x 2.^k], 2, 1][[All, All, -1]]; //
 AbsoluteTiming // First
digit1 == digit2 == digit3 == digit4
So, Mod and IntegerPart seem to do quite a good job, but still, there is a multiplication involved for each digit to be extracted.
Does anybody know of a fast, low-level way to retrieve the digits?
 - $\begingroup$ What I'd try for raw speed is write a C plugin where you cast the double into an unsigned long long int and extract the bits directly by masking, using info from en.wikipedia.org/wiki/IEEE_754 $\endgroup$ – Roman Jan 20 '19 at 20:40

 $\begingroup$ Correction: I've written a minimalistic C plugin that extracts a single binary digit directly by bit masking a uint64_t version of the double number. Even with all safety checks off, and MTensor processing inside the C function (i.e. only one function call for a large list of input numbers) this plugin just about as fast as your digit3. Not worth the trouble. In any case, as your digit3 takes only about 8 nanoseconds per conversion, I'm wondering what speed goal you had in mind? $\endgroup$ – Roman Jan 21 '19 at 17:16

 $\begingroup$ It's a shame BitAnd and BitShiftRight don't do what you think they would do on reals. $\endgroup$ – Chip Hurst Feb 4 '19 at 15:37
Not a complete answer
We can squeeze out a bit more speed by using BitAnd instead of Mod and BitShiftLeft instead of multiplication in your digit3 calculation.
Mod[IntegerPart[x 2.^k], 2]; // RepeatedTiming // First
BitAnd[IntegerPart[BitShiftLeft[x, k]], 1]; // RepeatedTiming // First
Mod[IntegerPart[x 2.^k], 2] == BitAnd[IntegerPart[BitShiftLeft[x, k]], 1]
I sought a solution that masked the bits via combinations of BitAnd and BitShiftRight, but to my surprise they don't work on Real as you might think.
BitAnd[1.0, 1]
BitAnd[1, 1.]
BitShiftRight[1.0, 1]
Though in its defense, C doesn't support bitwise operations on floats or doubles without casting to an integer type first.
Something like
double x = 1.0;
long n = *((long*)&x);
n >>= 1;
x = *((double*)&n);
gives 1.11875e-154 rather than 0.5, and it behaves how we might expect it to.
We can do something similar in WL through BinarySerialize and extracting bits by masking.
MantissaDigit[arr_?Developer'PackedArrayQ, k_Integer] /; $ByteOrdering == -1 && $SystemWordLength == 64 && 1 <= k <= 52 :=
 Block[{blvl1, blvl2, dims, start, bytes, bits},
 blvl1 = 6 - Quotient[k+3, 8];
 blvl2 = 8 - Mod[k+4, 8, 1];
 dims = Dimensions[arr];
 start = blvl1 - 8(Times @@ dims);
 bytes = BinarySerialize[arr][[start ;; -1 ;; 8]];
 bits = BitAnd[BitShiftRight[Normal[bytes], blvl2], 1];
 ArrayReshape[bits, dims]
Note that this implementation depends on $ByteOrdering and $SystemWordLength.
This however is slower than the digit3 technique:
MantissaDigit[x, k]; // RepeatedTiming
{0.021, Null}
One bottleneck is applying Normal, which is needed since bitwise operations don't work on ByteArray.

Android Quick Tip
Often times you'll want to tile, or repeat, a small image as the background of an Android view or layout. This is just like using the 'background-image' and 'background-repeat' CSS options, and almost as easy. First and most importantly, you'll need an image to tile. If you don't have one of your own, use the one below (right click and "Save Image").
Now, in your project's res/drawable path, create a file named tile_background.xml. Fill the file with the following XML:
1 2 3 4 5 6
Now all you have to do is set the android:background attribute of your target view or layout to the tile_background.xml drawable id, like so:
1 2 3 4 5 6 7 8 9
And if sample_layout.xml was the assigned content view for your main activity, you would see this when you started your app:

How long do you have to live? Life Expectancy Self Test
A simple test, developed by Dr. Claudio Gil Araujo can predict with uncanny accuracy, how much longer a person over 50 is likely to live. The test, called the Sitting Rise Test (SRT), can be done in just moments. In fact, you can do it right now. The SRT predicts how long you How long do you have to live? Self test infographic (image credit Roen Kelly/Discover)
Follow the steps above to perform the SRT – How long do you have to live?
have to live based on your balance, strength, and flexibility.
How to do the Test
Wear loose-fitting clothing. If you have difficulty keeping your balance, get somebody to stand by to catch you if you lose your balance during the test.
 1. Take your shoes off. Start from a standing position
 2. Bend your legs, drop straight down to the floor. Do not use your arms or legs for leverage, don't lean against anything
 3. Sit in a cross-legged sitting position
 4. Without using your arms, or leaning on anything, rise straight up, return to a standing position
How to Score the test
The SRT is scored on a scale of 1 – 10:
 - You get 5 points for going from standing to sitting position
 - You get 5 more points for returning to the standing position
 - Subtract 1 point each time you use an arm or knee to help you sit down or get up
 - Subtract a half point each time you lose your balance
 - Subtract a half point each time your movement becomes clumsy
What the test results mean
This test predicts your chances of dying early compared to a normal life expectancy. A score 8 points or less on the test indicates you're about twice as likely to die within the next six years. People who score three points or less are five times more likely to die within that same time period. Each point you get on the test is worth a 21-percent decrease in mortality:

The chart shows the percentage that your risk of dying in the next 6 years decreases with each point you earn.
What to do if you score poorly on this test
Don't panic! If you're reading this, there's still time to make changes that will help you score better on this test. The great news is, each point you can add to your score increases your potential life expectancy by a greater amount than the previous point. Here's what you need to do:
 - Posture – Good posture is essential to good health. Squat, don't bend over. Sit up straight in your chair. Bend your knees slightly when you stand. Walk on the balls of your feet – not your heels! You are much less likely to slip and fall with good posture
 - Yoga, Tai Chi, Belly Dance, etc. – Balance is critical to life expectancy. Many older people die each year from complications after a fall. Exercises that emphasize flexibility, balance and graceful movement help you avoid falls
 - Hydration – People often lose flexibility as they age, but proper hydration can preserve it. Alkaline water hydrates better than plain water. Exercise pushes water into the joints, so the better you can hydrate your body, the more water it has to lubricate your joints
 - Diet – If you are carrying excess weight, it is interfering with your balance. We recommend an alkaline diet along with alkaline water if you've had a hard time dropping the pounds
 - Exercise – Passing this test calls for strength in addition to balance and flexibility. If you can't lift yourself off the floor without help, speak with an athletic trainer so they can help you come up with an exercise plan.
Why this test works
Dr. Araujo noticed that many of his patients, especially older ones, had difficulty with simple feats of balance and strength. Balance and conditioning problems increase your risk of dangerous falls and accidents. They can also harm your cardiovascular health. Dr. Araujo theorized that a patient's flexibility, balance and strength could be used as a measure of life expectancy.
To find out if he was right, Dr. Araujo tried this test out on more than 2,000 of his patients aged 51 to 80. He found that he was able to predict their life expectancy with "alarming accuracy."
