The Whys and Hows of Demagnetizing Engine Components
By Jim Tapp
Retired Goodson Tech Services Manager
We get a lot of questions on the Tech Help Line about demagnetizing engine components. If you do a web search, there's a lot of differing information available. Some sources say it's not all that important, some say it's essential. Since we're getting these questions frequently, I thought I'd weigh in on the subject too.
In my mind, not demagnetizing components you've worked on is kind of like taking a bath, then putting your dirty clothes back on. Doesn't make a lot of sense and undoes all of the good work you've just done. So here goes. This is my view on whether or not to demag components:
Rebuilding engine components without removing the residual magnetism is flat out dangerous.
Magnetism is produced in engine components in a couple of ways.
 - Deliberately introducing a magnetic field into the part for the purpose of magnetic particle inspection (Magnafluxing).
 - Magnetizing parts with heat and/or friction such as when a connecting rod has bearing failure. This is the most common way that magnetism is introduced into engine parts.
The down side to this, and the point I'm trying to make, is that if the magnetism is not removed from the effected parts, engine failure is more likely to occur. Imagine a magnetic connecting rod in your engine. It's going to collect all of the metal particulates and use them to abrade your machine work.
So how do you tell that magnetism is present? Measure it. Magnetic fields are measured in gauss and the gauge used to measure it is a magnetic field indicator (Goodson #MFI-10010). To see if you have any residual magnetism in your components, simply hold the field indicator close to the part. If it doesn't read "0", you have magnetism.
Demagnetizing is accomplished by breaking up the D.C. (direct current) field with A.C. (alternating current). This is possible with the use of an A.C. demagnetizing table (Goodson #SPD-46). Place your part on the table top and turn the machine on. You will notice severe vibration. This is the A.C. attracting and repelling the part. While the machine is operating, slowly move the part away from the table to a distance of about two feet. Turn off the demag table and recheck the part with the magnetic field indicator. If the reading is not "0", repeat the procedure until it does.
Remember if you have questions, the Goodson Techxperts are as close as a phone call (_PHONE_) Monday – Friday, 8am to 5pm (central). You can also reach the techs by email or visit the Goodson Tech Library.

 I used to Mag' a lot of engine parts, and de-magging on our very large industrial mag bench wet or dry would require several presses of the de-mag button to get rid of the residual magnetic field. One day I decided to reverse the cables on the mag' wires, and viola'~! one press of the button and any item was at zero residual magnetism..

From the Huffington Post:
Gov. Arnold Schwarzenegger typically attaches a message to bills he signs or vetoes telling lawmakers why he took the action.
A Democratic assemblyman who heckled the governor during a recent event in San Francisco actually received two messages: the veto letter itself and a not-so-subtle rebuke creatively hidden within it.
Like a find-the-word puzzle, the second message was visible by stringing together the first letter of each line down the left-hand margin. It consisted of a common four-letter vulgarity followed by the letters "y-o-u."
Wow. So what's the verdict, people?
Hilarious coincidence or deliberate insult?

Power tool
 Whether it's a notepad in their glovebox, scratch paper on the dashboard or official IRM Redbook in their pocket, most cattle producers have some means of record-keeping nearby. But pen-and-paper may soon be replaced by high-tech tools for herd management that put the power of data in the palm of a producer's hands.
Years in the making, the PowerCalf Mobile App and web portal are now available to assist beef producers in recording and managing critical information, from calving records to feeding programs. Just like that little redbook, this information can be accessed anytime, anywhere, but MFA's PowerCalf app surpasses written records by putting that data to work in measuring and benchmarking herd performance with convenient, user-friendly technology unlike anything on the market.
The app was officially launched in August, but PowerCalf's beginnings go back to 2014, when MFA Director of Health Track Operations Mike John sought to create a program that would allow beef producers to take the information they collected and make it more useful. MFA would digitize, standardize and analyze that information to help producers make whole-herd management decisions. Then John and PowerCalf developers took that concept a step further. What if producers could input their own information as quickly as they could write it, chute-side and already standardized? Wouldn't that be valuable to their operations? What if they could run reports or sort by the animal's identification number? And what if they could do that from their phone, tablet or computer?
The development of the mobile app was driven by those goals, and MFA's information technology department has been building and refining the platform with the help of beta-testers across MFA's trade territory. Here's what a few of them had to say about this new power tool for their operation:
Tim Myers runs Blue Horn Ranch in Farmington, Mo. He and five employees have a lot to manage with 3,200 acres and 400 cows having roughly 374 calves a year.
"Whenever anyone on the ranch enters new data, it updates all of us," Myers said. "It's a very straightforward and easy process. None of us are very computer literate, but this app is just a touch screen, easy to use, common sense."
Myers began beta-testing the app in the fall of 2016 and has used it for three calving seasons. He recently received carcass information on the first set calves that went to market while he was using the app. The results were interesting. The difference between his top and bottom carcass was $552.
"If we have the ability to group cattle of like genetics and like size and sell in bigger numbers, the cow/calf operator has control of some of the market," Myers said. "If we can prove genetics and prove what they're going to do at the feedlot, it gives us the ability to demand more money and have more stability in our market. The only way you can do that is through data collection."
Likewise, tracking performance is also one of the main goals of app testers Alvin and Janet Braun who run approximately 200 head of cattle near Ste. Genevieve, Mo. The Brauns began renting and working the family farm in 2009 when Janet's father got sick. Since then, they've been retaining 20-30 heifers each year to build their herd.
 "Our record-keeping up until now has been a little pocket notebook that gets put in a drawer," Janet said. "This spring, we used the PowerCalf app to record birth and weaning weights, and I'm anxious to do that again in the fall. I want to accumulate that data and look at it in black-and-white to compare how our calves do in their individual herds and how they perform compared to each other."
For the past three years, the Brauns have sold calves straight off the farm, and they said with the PowerCalf app they will be able to provide more information for prospective buyers. Ultimately, they hope PowerCalf will help increase their profitability.
"The buyers are actually beginning to contact us," Alvin said. "It's a lot more beneficial to sell from here than to haul to an auction barn, and it puts more money in our pocket in the end. When we eventually start selling our heifers, we'll be able to easily access that animal's information and even be able to tell the buyers how their mothers and grandmothers performed."
University of Missouri Extension Livestock Specialist Kendra Graham sees many operations in the state, some with various methods of data collection and others without any at all. She and her family run Kollmeyer Family Farms in Farmington, Mo., and served as a PowerCalf beta-testers.
"I think any type of information-gathering and recordkeeping that we can have on the farm is beneficial," Graham said. "Identification is key to a lot of our production records, so if we can make it easier for producers to record that data, I think people are more inclined to collect that information."
Graham said once producers start recording some data, they're more likely to keep other key information.
"Whether it's feeding, feed-to-gain or even just weights," she said, "you can tell if your cattle are more or less productive."
Through the PowerCalf app, producers can document and verify health and genetics through the entire process. They can benchmark their herd against others in the state. They can track feed efficiency and reproductive rates. They can determine which cows are the most profitable and which ones are costing them money. Moreover, they can do all this through the app on their mobile device or the web portal and know their information is securely stored in the cloud.
"One of the most exciting things I see happening with PowerCalf is it's going to give MFA the ability to help our producers capture more value and be more economically viable," Stephen Daume, MFA livestock consultant, said. "With PowerCalf, I can now go out to a farm and help that customer look through his records—analyze his carcass weights, feed conversion, reproduction rates—and maybe even help him break his profitability down in terms of dollars of carcass weight per cow.
Ultimately, it's about MFA being able to help our producers capture more value out of the products they produce, which, in turn, adds value to what we do here at MFA."
PowerCalf not only has the potential to change producers' operations, but it may have the potential to change the beef industry as a whole, Daume said. Producers will now be able to tell which of their cows produce calves that grade well at the processor and meet consumer expectations of quality. The possibilities are endless.
"By capturing and digitizing all this data," he said, "we not only have the ability to document and verify parentage, but we can also make observations such as hair coat quality, fescue resistance or respiration rate during heat stress. We could maybe even identify lines and breeds of cattle that have specific resistance to disease, like bovine respiratory disease. The PowerCalf app is going to allow us to easily track those genetics, and we could assist with beef improvement not just here in Missouri or the United States, but perhaps even globally."
That's the power possible in the PowerCalf app. For more information, visit, the Apple store or Google Play. Hear more from these PowerCalf pioneers in this video at

Lush pastures can equal lung problems for cattle
This time of year, it is possible to move cattle off mature, dormant warm-season pastures onto cool-season pastures, which are lush, high in protein, wet and rapidly growing. However, in this situation, acute bovine pulmonary edema (ABPE) might be a concern. ABPE is more common in the fall than in the spring. This form of pneumonia typically occurs when cows are fed an all-dry dormant stage of growth forage and then are turned out on high-protein, wet pastures. A typical scenario is a grazing change in the late summer or fall from dry pastures to lush forage regrowth following haying.
ABPE can be avoided by introducing cattle to cool-season pastures over time. For example, limit their access to a few hours for a couple of days, then allow them to graze for a couple of mornings before letting them run full time on the pasture. This is much less of an issue if the pasture is mixed with small grains.
However, grazing management—not the forage—dictates the prevalence of ABPE. Swathing a section of the grass and allowing it to wilt before the animals eat it reduces the incidence. Feeding an ionophore, something with Rumensin or Bovatec, also helps reduce the chances of ABPE and improves the diet's energy value. Consider feeding a couple pounds of MFA Full Throttle to balance the energy-to-protein ratio and add vitamins, minerals and an ionophore. Preventing ABPE is crucial because there is no effective treatment for affected animals.
Technically speaking, here's why it happens. The lush, rapidly growing pastures contain an amino acid called tryptophan—a normal component found in protein. Rumen bacteria metabolize the tryptophan, converting it into a compound called 3-methylindole. This compound, in turn, is converted into another toxin that creates edema in the lungs. This fluid interferes with the breathing process and exchange of oxygen and can lead to animal mortality.
Because of the way we feed dairy cows, ABPE usually only occurs in beef cattle. Clinical signs of ABPE usually occur one to 14 days after an abrupt change in pasture

The MAQ®20 Python API uses an object-oriented approach for communicating with MAQ20 systems, which provides an intuitive interface where the low-level Modbus commands are hidden from normal use. Users can focus on solving the measurement problems at hand, instead of re-inventing how to communicate with modules.
Before using the MAQ20 Python API, you may find it helpful to be acquainted with basic Python programming and understand the concept of objects.
MAQ20 data acquisition system
MAQ20 Python API GUI Example
 - Communication: to MAQ20 systems from a host PC.
 - Address offsetting: When a module is registered in a system, addresses are offset by 2000 * R, where R is the Registration Number. The API uses relative addressing for the modules, this means that when using low-level Modbus commands, 0 to 1999 are valid addresses.
 - Counts to Engineering units: the API reads information it needs to know at initialization to do this conversion.
 - Rounding: when dealing with small quantities such as millivolts it can get tedious to look at a bunch of trailing decimals. The API does meaningful rounding to any module up to 3 significant units of Eng. units per count.

Frequently Asked Questions
I've noticed periodic positive and negative spikes in recorded temperature from my MAQ20-JTC module. How can I reduce these occurances?
The input to the MAQ20-JTC module is very sensitive. Movement of attached thermocouple wires can cause spikes in recorded data along with inherent noise present in different environments. Setting "Input Select" to the "Average" setting in ReDAQ Shape, or by direct Modbus commands can greatly reduce the variation in recorded channel data.
Signal Averaging can be set on a per-channel basis by configuring the Average Weight parameter. Average Weight is calculated as 2^x where x = 0 to 15 and the default value is x =0 . The running Average is calculated as follows: Average = Average + ((Sampled Value - Average) / Average Weight)
I'm unable to connect to my MAQ20 through an Ethernet connection. Is there a problem with my MAQ20-COM module?
To date there have been no occurrences of a MAQ20-COMx module being unable to be connected through an Ethernet connection as a result of an issue with the module's internal hardware/firmware. Connectivity issues can occur as a result of one, or a combination of the following factors: incorrect MAQ20-COMx settings, incorrect local network settings, incorrect host computer settings, network security settings, or IP address conflicts.
When shipped from factory, MAQ20-COMx modules come with the following default connectivity settings pre-loaded in memory:
IP Address: 192.168.128.100
Subnet Mask: 255.255.0.0
Gateway: 127.0.0.1
TCP Port: 502
Assuming the above-listed default settings are not changed, reserve a static IP address of 192.168.128.100 through your local network configuration. Assigning this IP address statically will ensure that no other devices on the network will be able to claim the IP address that is intended to be used by the MAQ20-COMx module.
If not using the default IP address, the statically reserved IP address on the local network MUST start with 192.168.xxx.xxx and MUST match the non-default IP address that was saved to MAQ20-COMx module memory located at start address 50. If you need to check the IP address saved at this register address you can connect to the MAQ20-COMx through a USB connection and use ReDAQ Shape to read the register address' contents. This functionality in ReDAQ Shape can be found by clicking the "Read / Write Modbus Registers" sub-tab located after clicking the main "Analyze" tab. No license for ReDAQ Shape is required to use this functionality. Please refer to the note at the bottom of this FAQ for the host computer requirements that MUST be met to allow for connectivity.
Alternatively, the MAQ20-COMx module can be set up for Ethernet connection using Dynamic Host Configuration Protocol (DHCP). To enable this functionality an IP address of 0.0.0.0 needs to be saved to the MAQ20-COMx's internal IP address register (Start address 50). You can write to this register through direct Modbus commands using the "Write Modbus Registers" feature located under the "Read / Write Modbus Registers" sub-tab in ReDAQ Shape. Changes to this address space will take effect upon power cycling the MAQ20 system. Once in DHCP mode, your local network will automatically assign an available IP address for the MAQ20-COMx module. You will need to access you local network configuration to determine what IP address was ultimately assigned to the MAQ20-COMx module. Once known, you can connect using the assigned IP address.
NOTE: In all motioned configurations the host computer that will be used to connect to the MAQ20-COMx module through the Ethernet connection MUST have an IP address of the form 192.168.xxx.xx (I.e. any IP address starting with 192.168. that does not match the one saved at start address 50 of the MAQ20-COMx module). The host computer MUST also have a Subnet Mask of 255.255.0.0.
Some of your MAQ20 modules have a burst scan mode, can I run this mode continuously to improve system throughput?
Burst scan mode is intended to be used for debugging and signal profiling purposes. It can not run continuously. Burst scan mode can capture samples to memory in magnitudes of microseconds, but it does not have the ability to read this data back from memory at this same rate.

Where Is the Safest Place to Sit on an Airplane?
It may not be where you think it is. I've often heard "within five rows of the exit row" cited as the safest area on the airplane.
And it makes sense logically–if you only have a short period of time to leave the plane, the closer to the exit, the better.
emergency row
But I haven't ever been able to find an actual study that says that. It just always seems to be a stat on a top 5 list.
But Popular Mechanics looked at the actual data, and this figure seems to be very wrong.
While people have died in a fire waiting to exit the plane (which is why you should not get your overhead baggage), we need to consider the fatalities that come from the crash itself.
And what did Popular Mechanics find?
For several weeks, we pored over reports filed by NTSB crash investigators, and studied seating charts that showed where each passenger sat and whether they lived or died. We then calculated the average fore-and-aft seating position of both survivors and fatalities for each crash.
We also compared survival rates in four sections of the aircraft. Both analytical approaches clearly pointed to the same conclusion: It's safer in the back.
I had seriously internalized the statistic about sitting near the exit doors, so this came as a huge surprise to me.
Mythbusters also studied what seating arrangement would result in the fewest fatalities–but it would literally mean changing around the seating.
They found that sitting backwards lessens your chance of dying on impact (but increases your chance of getting hit in the face with debris from the impact).
So maybe being by a door will get you out faster, but sitting in the back could save you on the initial impact.
(And yes, you should brace upon impact).

 1. Should be common sense. Planes fall out of the sky or crash into things making the back safest & 1st class the dumb zone.
 2. When booking travel for my family I always book the back of the plane. They always whine & complain, but my anxiety prefers to have statistics on my side.
 3. As a safety engineer, I'm well aware of this (yes, I study aviation disaster/root cause failures for fun). But I travel quite a bit for work. At least 4 flights per month, as many as 10. I still select seats toward the front. I grapple with it sometimes, but statistics are on my side. You may be x% "safer" sitting in the rear during a crash, but if the crash is only 0.00000x% likely to occur, then is it worth the additional 10 minutes PER FLIGHT spent waiting to deboard?
 I know the answer for ME is no. I'd rather get off a bit sooner. Or be upgraded 😛
 4. its a proven fact that the aft section is safer during an accident. Been a flight attendant for 29 yrs, and I always work the back of the plane. Even when I fly nonrev–I sit in the back. It all depends on the nature of the accident, but usually you are safer in the back, and on numerous occasions when boarding and I hear /talk to my pax, and they r griping about being in the aft section, I politely tell them its the safest part of the aircraft, otherwise I wouldn't be working in the back. then they stop andr ealizew hat ive said. be safe everyone
 5. Its a proven fact that sitting in the aft section is safer. But I guess that depends on the type of incident/accident. As a flight attendant I always work the back of the plane(where the black box is) Even when im non revving I sit in the back.

Loading Deferred Content (WCF Data Services)
By default, WCF Data Services limits the amount of data that a query returns. However, you can explicitly load additional data, including related entities, paged response data, and binary data streams, from the data service when it is needed. This topic describes how to load such deferred content into your application.
When you execute a query, only entities in the addressed entity set are returned. For example, when a query against the Northwind data service returns Customers entities, by default the related Orders entities are not returned, even though there is a relationship between Customers and Orders. Also, when paging is enabled in the data service, you must explicitly load subsequent data pages from the service. There are two ways to load related entities:
 - Eager loading: You can use the $expand query option to request that the query return entities that are related by an association to the entity set that the query requested. Use the Expand method on the DataServiceQuery to add the $expand option to the query that is sent to the data service. You can request multiple related entity sets by separating them by a comma, as in the following example. All entities requested by the query are returned in a single response. The following example returns Order_Details and Customers together with the Orders entity set:
 // Define a query for orders that also returns items and customers.
 DataServiceQuery query =
 WCF Data Services limits to 12 the number of entity sets that can be included in a single query by using the $expand query option.
 - Explicit loading: You can call the LoadProperty method on the DataServiceContext instance to explicitly load related entities. Each call to the LoadProperty method creates a separate request to the data service. The following example explicitly loads Order_Details for an Orders entity:
 // Explicitly load the order details for each order.
 context.LoadProperty(order, "Order_Details");
When you consider which option to use, realize that there is a tradeoff between the number of requests to the data service and the amount of data that is returned in a single response. Use eager loading when your application requires associated objects and you want to avoid the added latency of additional requests to explicitly retrieve them. However, if there are cases when the application only needs the data for specific related entity instances, you should consider explicitly loading those entities by calling the LoadProperty method. For more information, see How to: Load Related Entities (WCF Data Services).
When paging is enabled in the data service, the number of entries in the feed that the data service returns is limited by the configuration of the data service. Page limits can be set separately for each entity set. For more information, see Configuring the Data Service (WCF Data Services). When paging is enabled, the final entry in the feed contains a link to the next page of data. This link is contained in a DataServiceQueryContinuation object. You obtain the URI to the next page of data by calling the GetContinuation method on the QueryOperationResponse returned when the DataServiceQuery is executed. The returned DataServiceQueryContinuation object is then used to load the next page of results. You must enumerate the query result before you call the GetContinuation method. Consider using a do…while loop to first enumerate the query result and then check for a non-null next link value. When the GetContinuation method returns null (Nothing in Visual Basic), there are no additional result pages for the original query. The following example shows a do…while loop that loads paged customer data from the Northwind sample data service.
// With a paged response from the service, use a do...while loop
// to enumerate the results before getting the next link.
 // Write the page number.
 Console.WriteLine("Page {0}:", pageCount++);
 // If nextLink is not null, then there is a new page to load.
 if (token!= null)
 // Load the new page from the next link URI.
 response = context.Execute(token)
 as QueryOperationResponse;
 // Enumerate the customers in the response.
 foreach (Customer customer in response)
 Console.WriteLine("\tCustomer Name: {0}", customer.CompanyName);
// Get the next link, and continue while there is a next link.
while ((token = response.GetContinuation())!= null);
When a query requests that related entities are returned in a single response together with the requested entity set, paging limits may affect nested feeds that are included inline with the response. For example, when a paging limit is set in the Northwind sample data service for the Customers entity set, an independent paging limit can also be set for the related Orders entity set, as in the following example from the Northwind.svc.cs file that defines the Northwind sample data service.
// Set page size defaults for the data service.
config.SetEntitySetPageSize("Orders", 20);
config.SetEntitySetPageSize("Order_Details", 50);
config.SetEntitySetPageSize("Products", 50);
// Paging requires v2 of the OData protocol.
config.DataServiceBehavior.MaxProtocolVersion =
In this case, you must implement paging for both the top-level Customers and the nested Orders entity feeds. The following example shows the while loop used to load pages of Orders entities related to a selected Customers entity.
while (nextOrdersLink!= null)
 foreach (Order o in c.Orders)
 // Print out the orders.
 Console.WriteLine("\t\tOrderID: {0} - Freight: ${1}",
 o.OrderID, o.Freight);
 // Load the next page of Orders.
 var ordersResponse = context.LoadProperty(c, "Orders", nextOrdersLink);
 nextOrdersLink = ordersResponse.GetContinuation();
For more information, see How to: Load Paged Results (WCF Data Services).
WCF Data Services enables you to access binary large object (BLOB) data as a data stream. Streaming defers the loading of binary data until it is needed, and the client can more efficiently process this data. In order to take advantage of this functionality, the data service must implement the IDataServiceStreamProvider provider. For more information, see Streaming Provider (WCF Data Services). When streaming is enabled, entity types are returned without the related binary data. In this case, you must use the GetReadStream method of the DataServiceContext class to access the data stream for the binary data from the service. Similarly, use the SetSaveStream method to add or change binary data for an entity as a stream. For more information, see Working with Binary Data (WCF Data Services).

30 Days of Prayer Int'l
Colorado Springs, CO
Afghans have been fleeing their homeland for years, but the exodus grew more intense as Kabul fell into Taliban hands and Talib fighters became more open about persecuting and killing people they do not approve of. Thankfully, Tajikistan was one of the nations that was willing to host Afghan refugees.
Last year the Afghan refugee population in Tajikistan numbered about 5,000. Many of these have been in Tajikistan for 5 or 10 years or longer. These Afghans are from all the major ethnic groups in their home country (Pashtu, Hazara, Tajiks, Uzbeks, etc.) and are practicing Muslims.
Tajikistan offered safety but not much more. Many refugees are merely existing there. Despite a close cultural and language affinity, they have little hope of building a stable life in Tajikistan. Around 80% of Afghan men and women in Tajikistan are unemployed and there is little material support from their host country. Sadly, there there are no prospects of gaining citizenship either. Afghan refugees suffer from the trauma of persecution and flight, depression, hopelessness, poverty and the ever present fear of deportation back to their home country. For the few followers of Jesus amongst them (estimated at about 300 to 400), added to this is exclusion and rejection – particularly from their own families.
Most Afghan refugees want to leave the country for Canada or the USA. To do this, they need a sponsor who will bear the costs and vouch for the new arrivals. Almost all refugees place their hope in this option but it is a long and difficult journey.

How to Pray
- Pray that God will provide the refugees encouragement and hope for the future.
- Ask God that that those suffering from trauma will receive professional help and healing for the pains and losses.
- Pray for steadfastness and comfort for the Afghan followers of Jesus who experience rejection, separation from community and persecution.

From press release
Children are invited to "Exploration Monday: Moon Day" from 10 a.m. to 3 p.m., Monday, July 26, at Burpee Museum of Natural History, 737 N. Main St., Rockford. This is a drop-in program—learn some fun facts, see special items from Burpee's collection and make a "make & take" project.
July 26, 1969, at 3:55 p.m., a "rock box" containing rocks that Apollo 11 astronauts brought back from the moon was first opened. Learn more about what scientists discovered.
Museum admission is free/donation; cost of this program is $3 per child to participate. Free participation is offered for the first 30 Rockford Public School District 205 students who bring a picture they have drawn or a short piece they have written about the moon.
Celebrate the full moon of July by taking part in Moon Day at Burpee's Exploration Monday! There are lots of crafts to complete, and kids will discover many interesting facts about the moon. Participants will learn the phases of the moon. You will find your weight on the moon as well as create craters just like those on the moon. Additional crafts include making moon sand, a moon kinescope, a moon book, a moon mask, moon painting, and a moon rock. Crafts are for the smallest to the oldest.
In the wigwam, representatives of the Native American Awareness Committee of Rockford will be telling stories. You can pretend to be a little child living under the full moon and listening to stories long ago before you fell asleep.
Artist Melinda Peterson Fluait will be at Burpee also that day for "Draw with Melinda." Children will create their own silhouette on the face of a full moon.
→ Countries near the equator see the crescent moon shaped like a smile.
→ It takes the moon about 29.5 days to completely cycle through all eight phases. This is known as a lunar month.
→ The moon phases are produced by the alignment of the moon and the sun in the sky.
→ The moon is lit because it reflects the light from the sun.
→ The part facing the sun is lit, while the part facing away from the sun is dark.
For more information, call Burpee Museum at _PHONE_.

Streamline Chub (Erimystax dissimilis)
The Streamline Chub is found in several disjunct populations in the Ohio River Drainage from Alabama to New York, including the Tennessee and Cumberland river drainages. They are found in riffles and runs of large streams and rivers over rock and gravel bottoms. As the common name suggests, Streamline Chubs have a "streamline" body shape that is long and slender to help maintain their position in swift water. They are disappearing throughout their range due to reservoir construction and siltation.

Ports are faster than packages?

Yes. Which means no. :-)
In general, the set of options with which the binary packages
are built by the FreeBSD port building and delivering systems
is to make sure the port works well in most possible cases.
For edge cases, where different compile-time options might
be needed, the user has no other choice than building from
source. This enables two possibilities:
1. increasing features, which might increase resource usage
 and add further dependencies, or
2. reduce features, and apply platform-specific optimization,
 which can lead to faster programs.
Especially the part of options that effect optimization has
been a valuable help in the past, for example, when you
wanted to run a program on a low-spec system, you could
add optimization for that system, and the program would
then run faster than the corresponding "canned" package.
Technically, a port installed from source is nothing else
than a binary package: The building process creates a
package, the package is then installed. It doesn't matter
to pkg if a package comes from a local source of from the
FreeBSD server. _That_ doesn't make anything slower or
faster. But as I said, tweaking the options to deviate
from the standard building options _can_ have that effect,
but it can also have the exact opposite effect.
So the difference is not "port or package", because it's
the same, the difference is what options have been in
effect when building from source, no matter where that
happens.

I am working on a project that will involve having several RPi kiosks set up across a college campus. In the rare event that someone might accidentally/maliciously disconnect the power cord from one of the RPis, the associated kiosk would obviously stop working.
I would like to automatically get email notifications if this happens so that I would be aware of it immediately, but I don't know how to do this or even if it is possible. Any ideas?

 this is called a "dead man's switch". if it's web-accessible there are a lot of options. but to tell that something is dead you need a nondead device watching it. dead servers don't talk. – tedder42 Jun 4 '16 at 0:35
It's certainly possible, but it'll require additional hardware. Once the RPi loses power, that's it. Just like your desktop, there's no magical way for the RPi to do anything (like send a notification) once the power is gone.
You could add a small UPS to the RPi. There are a few that are even designed specifically for the RPi, like this one. If the power goes out, the UPS will send a notification to the RPi. Then the RPi can handle sending a message across the network. If you're fast enough, the RPi may never experience downtime. If you're not fast enough, the RPi can gracefully shutdown.
Alternatively, you could add microcontroller to monitor the power and send a message if needed. Something like this should be able to run off a battery for along time.
I think the best and simplest option though would be to ping the RPi on a set schedule. Since your RPi is a network attached kiosk, you obviously can contact it through said network. Why not just setup a handshake every 1/5/60/whatever minutes? This could be as simple as a script on your server or even desktop workstation that just pings a list of IPs/Hosts and then notifies you which ones don't answer.
 1. Create an AWS account.
 2. Create a tiny text file that just contains something like "hello" or "alive"
 3. Create a S3 bucket for your project. Copy your tiny text file N times into that bucket, once for each Pi that you need to keep status on. Use unique filenames like pi1, pi2, pi3,..., piN.
 4. On each pi, create a simple shell script run by cron every minute that grabs that pi's text file via wget or curl.
 5. Enable S3 access logging
 6. On a separate Pi or an EC2 instance, write a script that regularly downloads the S3 logs and checks to see that all of the pi files have been recently accessed. Note that S3 access logging isn't instantaneous, so you may have a 20-30 minute lag before you discover that one of your Pis is down.
There are commercial server monitoring services like New Relic, but they may be too expensive for your application.

The monitoring of the Transmission Control Protocol (TCP) state variables can provide an understanding of how various traffic flows on a network interact. As discussed in previous work the rate and diversity of the raw information available is incomprehensible in real time, considering human cognitive processing limitations. In this paper, the authors will demonstrate a solution to the problem of monitoring the attributes of TCP flows by projecting them as orthogonal visual characteristics on 3D entities displayed inside a modified game engine, known as L3DGEWorld.

WPF PerspectiveCamera LookDirection
I have been converting a bunch of demos to the November CTP of WPF and I came upon an interesting problem. The LookAtPoint property of PerspectiveCamera was changed to LookDirection. So I happily renamed it, compiled and ran, but nothing appeared inside of the Viewport3D. I asked Tim Sneath if there was anything that might cause this. He pointed out that LookDirection is a Vector3D instead of a Point3D. My LookDirection was set to (0,0,0). This worked great for LookAtPoint because (0,0,0) is a valid 3D point to look at, but (0,0,0) doesn't work for LookDirection.
When I asked Jordan Parker of the WPF team for an explanation of what was happening he explained that the definition of LookDirection is LookAtPoint – Position. You will end up with a zero length vector if LookAtPoint = Poisiton. A zero vector is not a viable direction. Ok so that explains why I don't see anything, now how do I fix it?
This diagram shows how cameras worked with LookAtPoint and how they work with LookDirection. I have done this in 2D to make explanation easier. On the left I have two cameras marked with blue arrows. They both have a LookAtPoint set to (1,1) so regardless of what there position is they will look at the green dot. On the right I have two cameras marked with red arrows showing how things LookDirectionwork with LookDirection. The red camera in the lower left at position (-2,-2) is pointing at the green dot because it's LookDirection is set to (1,1), but the other red camera at position (2,2) is not facing the green dot because it too has a LookDirection set to (1,1). Note that the reason that the camera a position (2,2) can't see the green dot is because of the direction it's facing. To get the red camera at position (2,2) to look towards the green dot we would need to set the LookDirection to (-1,-1), which would cause the camera to face directly towards the green dot, because of the camera's position. Something to note here is that a camera doesn't actually look at a single point it looks at all the points in the direction it's facing. Also the LookDirection is normalized so there is no difference between setting the LookDirection to (1,1) or (100,100), they would both result in the camera facing in the same direction.
In the demo I am porting the camera is looking at a box and rotating the camera around the box. I could just rotate the box. Instead I used Jordan's definition of LookDirection and subtracted the position I wanted to look at from the camera position. This gives me the direction I should apply to LookDirection. If I wanted to look at (0,0,0) I would do something like the following every time I updated my camera position.
PerspectiveCamera pc = (PerspectiveCamera)this.Camera;
Point3D objectPosition = new Point3D(0,0,0);
pc.LookDirection = new Vector3D(objectPosition.X – pc.Position.X, objectPosition.Y – pc.Position.Y, objectPosition.Z – pc.Position.Z);


How to Store and Retrieve User Settings from SUSI Server in SUSI iOS
Any user using the SUSI iOS client can set preferences like enabling or disabling the hot word recognition or enabling input from the microphone. These settings need to be stored, in order to be used across all platforms such as web, Android or iOS. Now, in order to store these settings and maintain a synchronization between all the clients, we make use of the SUSI server. The server provides an endpoint to retrieve these settings when the user logs in.
First, we will focus on storing settings on the server followed by retrieving settings from the server. The endpoint to store settings is as follows:
_URL_
This takes the key value pair for storing a settings and an access token to identify the user as parameters in the GET request. Let's start by creating the method that takes input the params, calls the API to store settings and returns a status specifying if the executed successfully or not.
 let url = getApiUrl(UserDefaults.standard.object(forKey: ControllerConstants.UserDefaultsKeys.ipAddress) as! String, Methods.UserSettings)
 _ = makeRequest(url, .get, [:], parameters: params, completion: { (results, message) in
 if let _ = message {
 completion(false, ResponseMessages.ServerError)
 } else if let results = results {
 guard let response = results as? [String : AnyObject] else {
 completion(false, ResponseMessages.ServerError)
 return
 }
 if let accepted = response[ControllerConstants.accepted] as? Bool, let message = response[Client.UserKeys.Message] as? String {
 if accepted {
 completion(true, message)
 return
 }
 completion(false, message)
 return
 }
 }
 })
Let's understand this function line by line. First we generate the URL by supplying the server address and the method. Then, we pass the URL and the params in the 'makeRequest' method which has a completion handler returning a results object and an error object. Inside the completion handler, check for any error, if it exists mark the request completed with an error else check for the results object to be a dictionary and a key 'accepted', if this key is 'true' our request executed successfully and we mark the request to be executed successfully and finally return the method. After making this method, it needs to be called in the view controller, we do so by the following code.
Client.sharedInstance.changeUserSettings(params) { (_, message) in
 DispatchQueue.global().async {
 self.view.makeToast(message)
 }
}
The code above takes input params containing the user token and key-value pair for the setting that needs to be stored. This request runs on a background thread and displays a toast message with the result of the request.
Now that the settings have been stored on the server, we need to retrieve these settings every time the user logs in the app. Below is the endpoint for the same:
_URL_
This endpoint accepts the user token which is generated when the user logs in which is used to uniquely identify the user and his/her settings are returned. Let's create the method that would call this endpoint and parse and save the settings data in the iOS app's User Defaults.
if let _ = message {
 completion(false, ResponseMessages.ServerError)
} else if let results = results {
 guard let response = results as? [String : AnyObject] else {
 completion(false, ResponseMessages.ServerError)
 return
 }
 guard let settings =
response[ControllerConstants.Settings.settings.lowercased()] as? [String:String] else {
 completion(false, ResponseMessages.ServerError)
 return
 }
 for (key, value) in settings {
 if value.toBool() != nil {
 UserDefaults.standard.set(value.toBool()!, forKey: key)
 } else {
 UserDefaults.standard.set(value, forKey: key)
 }
 }
 completion(true, response[Client.UserKeys.Message] as? String ?? "error")
}
Here, the creation of the URL is same as we created above the only difference being the method passed. We parse the settings key value into a dictionary followed by a loop which loop's through all the keys and stores the value in the User Defaults for that key. We simply call this method just after user log in as follows:
Client.sharedInstance.fetchUserSettings(params as [String : AnyObject]) { (success, message) in
 DispatchQueue.global().async {
 print("User settings fetch status: \(success) : \(message)")
 }
}
That's all for this tutorial where we learned how to store and retrieve settings on the SUSI Server.

Did you know that newborn babies have the most water? An average newborn is roughly 75% water, a level that decreases as we age, dropping to about 50% for an elderly person.
The amount of water inside the body throughout the course of its life also varies depending on what shape that body is in. The more muscular a body is, the more water it contains. Conversely, the more fat there is in a body, the less water there is, because the water-content of fat is low. Our vital organs, like the brain, lungs, heart, liver, and kidneys, contain between 65% to 85% water*, while bones contain around 30%.

When working with a multi-terrain setup, it often happens that you get unwanted seams or steps in your world - either on the border between two terrains, or at the edge of a stamp. This article explains how you can get rid off those seams in an elegant way with the stamper in Gaia 2 / Pro.
Our example setup: Two terrains with unaligned heights between the borders.
1. Remove all masks from the stamper. Set the Operation Type to "Set Height", then Add a Distance Mask with
Influence: Global
Axes: X or Z, depending on which axis your seam / edge runs across.
For the Distance Mask Curve set up a hill-like curve. Combined your mask settings should look like this:
You should now be seeing some "hill-like" structure that mimics the curve of the distance mask when the stamp preview is enabled, depending on the height of the stamper it should either be a hill or a valley in your existing terrains:
2. Position the Stamper exactly above the edge you want to blend away. You can experiment a bit with the height to decide at which height the transition should take place:
3. In theory you can stamp now and the two terrains will be merged according to the stamp preview. However you will notice that the seam area will look a bit bland and featureless. You can change this by adding an additional image mask, then selecting a stamp image that shows interesting features that you would like to see in the transition:
Keep in mind that you can just open the stamp browser to flip through the available stamps,the preview will update accordingly:
If you are happy with the result, you can press the stamp button, and you should see your stamp / edge being replaced with the transition you just created. Here are the two terrains from the example setup at the beginning:
If you don't like the transition taking place over such a large area across your world, you can also fine tune the curve, but if you overdo it, it might become obvious that thereis some sort of artifical transition going on between the terrains:

Coloured wax model of a female, half skeletal, half living and dressed in regency clothing, England, _PHONE_
This lady is dressed in Regency clothing typical of the first half of the 1800s. She is skilfully created out of wax. She is half woman, half skeleton. The statue may have been made for one of three reasons: a darkly comic novelty, a 'memento mori' (a reminder of death), or a teaching aid. She is paired with a separate male statue (A78827). These two examples of regency waxwork were exhibited in Montreal, Canada at the International and Universal Exposition in 1967.

TRANSITION | CONSOLIDATE | FINALIZE functions. There is one predefined MAP function named IDENTITY that returns (key, value) pairs unchanged. Although (key, value) are the default parameters, you can specify other prototypes as needed.
- TRANSITION | CONSOLIDATE | FINALIZE
- TRANSITION, CONSOLIDATE and FINALIZE are all component pieces of REDUCE. A TRANSITION function is required. CONSOLIDATE and FINALIZE functions are optional. By default, all take state as the first of their input PARAMETERS, but other prototypes can be defined as well.
A TRANSITION function iterates through each value of a given key and accumulates values in a state variable. When the transition function is called on the first value of a key, the state is set to the value specified by INITIALIZE of a REDUCE job (or the default state value for the data type). A transition takes two arguments as input; the current state of the key reduction, and the next value, which then produces a new state.
- If a CONSOLIDATE function is specified, TRANSITION processing is performed at the segment-level before redistributing the keys across the Greenplum interconnect for final aggregation (two-phase aggregation). Only the resulting state value for a given key is redistributed, resulting in lower interconnect traffic and greater parallelism. CONSOLIDATE is handled like a TRANSITION, except that instead of (state + value) => state, it is (state + state) => state.
- If a FINALIZE function is specified, it takes the final
state produced by CONSOLIDATE (if present) or
TRANSITION and does any final processing before emitting the
final result. TRANSITION and CONSOLIDATE
functions cannot return a set of values. If you need a
REDUCE job to return a set, then a FINALIZE is
necessary to transform the final state into a set of output values.
- Required. A name for the function. Names must be unique with regards to the names of other objects in this MapReduce job (such as function, task, input and output names). You can also specify the name of a function built-in to Greenplum Database. If using a built-in function, do not supply LANGUAGE or a FUNCTION body.
- Optional. Specifies the full body of the function using the specified LANGUAGE. If FUNCTION is not specified, then a built-in database function corresponding to NAME is used.
- Required when FUNCTION is used. Specifies the implementation language used to interpret the function. This release has language support for perl, python, and C. If calling a built-in database function, LANGUAGE should not be specified.
- Required when LANGUAGE is C (not allowed for other language functions). To use this attribute, VERSION must be 18.104.22.168. The specified library file must be installed prior to running the MapReduce job, and it must exist in the same file system location on all Greenplum hosts (master and segments).
- Optional. Function input parameters. The default type is
MAP default - key text, value text
TRANSITION default - state text, value text
CONSOLIDATE default - state1 text, state2 text (must have exactly two input parameters of the same data type)
FINALIZE default - state text (single parameter only)
- Optional. The default return type is
MAP default - key text, value text
TRANSITION default - state text (single return value only)
CONSOLIDATE default - state text (single return value only)
FINALIZE default - value text
- Optional optimization parameters for the
STRICT - function is not affected by NULL values
IMMUTABLE - function will always return the same value for a given input
- Optional. Specifies the number of rows returned by the function.
MULTI - returns 0 or more rows per input record. The return value of the function must be an array of rows to return, or the function must be written as an iterator using yield in Python or return_next in Perl. MULTI is the default mode for MAP and FINALIZE functions.
SINGLE - returns exactly one row per input record. SINGLE is the only mode supported for TRANSITION and CONSOLIDATE functions. When used with MAP and FINALIZE functions, SINGLE mode can provide modest performance improvement.
- Required. A REDUCE definition names the TRANSITION | CONSOLIDATE | FINALIZE
functions that comprise the reduction of (key,
value) pairs to the final result set. There are also several
predefined REDUCE jobs you can execute, which all operate over a
column named value:
IDENTITY - returns (key, value) pairs unchanged
SUM - calculates the sum of numeric data
AVG - calculates the average of numeric data
COUNT - calculates the count of input data
MIN - calculates minimum value of numeric data
MAX - calculates maximum value of numeric data
- Required. The name of this REDUCE job. Names must be unique with regards to the names of other objects in this MapReduce job (function, task, input and output names). Also, names cannot conflict with existing objects in the database (such as tables, functions or views).
- Required. The name of the TRANSITION function.
- Optional. The name of the CONSOLIDATE function.
- Optional. The name of the FINALIZE function.
- Optional for text and float data types. Required for all other data types. The default value for text is ''. The default value for float is 0.0. Sets the initial state value of the TRANSITION function.
- Optional. Defaults to [key, *]. When using a multi-column reduce it may be necessary to specify which columns are key columns and which columns are value columns. By default, any input columns that are not passed to the TRANSITION function are key columns, and a column named key is always a key column even if it is passed to the TRANSITION function. The special indicator * indicates all columns not passed to the TRANSITION function. If this indicator is not present in the list of keys then any unmatched columns are discarded.
- Optional. A TASK defines a complete end-to-end
INPUT/MAP/REDUCE stage within
a Greenplum MapReduce job pipeline. It is similar to EXECUTE except it is not immediately executed. A task
object can be called as INPUT to
further processing stages.
- Required. The name of this task. Names must be unique with regards to the names of other objects in this MapReduce job (such as map function, reduce function, input and output names). Also, names cannot conflict with existing objects in the database (such as tables, functions or views).
- The name of an INPUT or another TASK.
Optional. The name of a MAP function. If not specified, defaults to IDENTITY.
Optional. The name of a REDUCE function. If not specified, defaults to IDENTITY.
- Required. EXECUTE defines the final INPUT/MAP/REDUCE stage within a Greenplum MapReduce job pipeline.

Check Balance selects nested expressions (for example, parenthesized) outward from the insertion point.
To select a nested expression, select anywhere within the expression by clicking. Choose Check Balance, and click to expand the selection out to the next set of enclosed parentheses, brackets, or braces.
Each time you choose Check Balance, Mathematica expands the selection in both directions until it finds pairs of matching parentheses, brackets, or braces. Repeating the command expands the selection one level at a time.
You can use the Check Balance command to check the structure of mathematical expressions. For example, if you have unbalanced parentheses or parentheses incorrectly balanced with brackets or braces, Mathematica beeps. Choose Help ► Why the Beep? to identify the mistake. If you position the insertion point inside a bracketed expression and choose Check Balance, Mathematica should select the whole expression. If not, you have a missing bracket somewhere.
Mathematica cannot balance a selection that spans more than one cell.


text: YEREVAN (Noyan Tapan)–A new theory of eye movemen's proposed by Armenian scientist Varlam Galoyan not only explains certain eye diseases–but often helps to prevent such visual defect. The theoretical model of eye movement is based on 43 scientific disciplines–including physiology–mathematics–biophysics–ophthalmology and others. The model describes all main interactions of the eyeball and its environment–taking into account hydro-mechanical force and friction–which are–at times–neglected in the traditional approach. Galoyan's model explains the appearance of different types of strabismus–short-sightedness and several other eye diseases. According to the theory–in most cases visual defects emerge within the first months of life–when the child lacks co-ordination of eye movemen's–and the sharpness of vision is minimal. To form a good vision and equal development of both eyes–Galoyan suggests to evade mechanical strain of the eyeball–which happens through the negative pressure formed through the incorrect position of the body and head of the child. For example–if a child lies with his face down for a long time–there is a possibility of appearance and development of progressive short-sightedness. This fact had been experimentally proven in the 30's–however–the scientific reasoning is now available in Galoyan's theory. The author sees a practical way out of the prophylactic ophthalmology. According to him–formation of the eyeball can be regulated in different ages–using a static loading on the eyeball via setting child's body and head in a certain position–for example–on the back. The work is being done through assistance of the Russian Institute for Information Transmission. The results have been presented at international conferences and published in the leading scientific editions of the former USSR and abroad.

A PUF is expected to generate responses containing ideally the same number of logic-0s and logic-1s. Therefore, the uniformity metric (also called randomness by Yu et al. in ) can be exploited to estimate the distribution of logic-0 and logic-1 in PUF responses. Let N be the number of response bits, the percentage measure for uniformity of response r = (г,0, гц, ... ritN_1) can be defined as
A value of 100% means that all r response bits are logic-1. For true random bits, uniformity should be as close as possible to its ideal value of 50 %. Let R be the number of responses, resulting from the product between the amount of different
PUF instances and input challenges (if any). The average uniformity for a population or R devices can be calculated as
The uniformity metric is not enough to qualify the randomness of PUFs responses. Indeed, even with a best value of bit uniformity, some homologous bits could turn out to be biased among the responses of the PUF population. This could happen whenever the manufacturing process introduces static variations which compromise all the homologous bits in the responses, causing a fixed preferred value. To this aim, we can compute the bit aliasing (also called bias in ) as
If some homologous bits are biased, the bit-aliasing results in a value far from 50 %.


Serialization - extended_type_info
C++ Boost
Runtime Interface
The serialization library needs a system like type_info/typeid() to perform the following functions
 1. given a pointer to a type T discover the true type pointed to.
 2. given an "external" key - determine what type of object to create.
The problem with std::type_info
extended_type_info is an implementation of std::type_info functionality with the following features: Exported types are maintained in a global table so that given a string key, the corresponding type can be found. This facility is used by the serialization library in order to construct types serialized through a base class pointer.
Runtime Interface
namespace boost {
namespace serialization {
class extended_type_info
 // this class can't be used as is. It's just the
 // common functionality for all type_info replacement
 // systems. Hence, make these protected
 const char * m_key;
 extended_type_info(const unsigned int type_info_key);
 void key_register(const char *key);
 const char * get_key() const {
 return m_key;
 bool operator<(const extended_type_info &rhs) const;
 bool operator==(const extended_type_info &rhs) const;
 bool operator!=(const extended_type_info &rhs) const {
 return!(operator==(rhs));
 // for plugins
 virtual void * construct(unsigned int count = 0,...) const;
 virtual void destroy(void const * const p) const;
 static const extended_type_info * find(const char *key);
} // namespace serialization
} // namespace boost
Generally, there will be one and only one extended_type_info instance created for each type. However, this is enforced only at the executable module level. That is, if a program includes some shared libraries or DLLS, there may be more than one instance of this class correponding to a particular type. For this reason the comparison functions below can't just compare the addresses of this instance but rather must be programmed to compare the the actual information the instances contain.
extended_type_info(unsigned int type_info_key);
This constructor should be called by all derived classes. The argument should be the particular implementation. For this default implementation base on typeid(), this is the value 1. Each system must have its own integer. This value is used to permit the inter-operability of different typeinfo systems.
void key_register(const char *key);
Assign a unique character string identifier to this extended_type_info instance and add it to the corresponding global trable. This key is used to identify a type accross different instances of the program. In this way, one instance may know what type to create when necessary. For this purpose, it must be the same in all program instances which refer to the same type.
It may sometimes be referred to as a GUID - a Global Unique IDentifier.
const char *get_key() const;
Retrieves the key for extended_type_info instance. If no key has been associated with the instance, then a NULL is returned.
bool operator<(const extended_type_info & rhs) const;
bool operator==(const extended_type_info & rhs) const;
bool operator!=(const extended_type_info & rhs) const;
These functions are used to compare two extended_type_info objects. They a strict total ordering on all instances of this class.
Construct a new instance of the type to which this extended_type_info record corresponds. This function takes variable list of up to 4 arguments of any type. These arguments are passed to the type's constructor at runtime. In order to use the facility, one must declare a type sequence for the constructor arguments. Arguments for this function must match in number and type with those specified when the type was exported. This function permits one to create instances of any exported type given only the exported GUID assigned with BOOST_CLASS_EXPORT. If these types are defined in DLLS or shared libraries. When these modules are loaded at runtime, these constructor can be called until the module is unloaded. These modules are referred to as plugin.
virtual void destroy(void const * const p) const;
Destroy an instance created by the above constructor.
static const extended_type_info * find(const char *key);
Given a character string key or GUID, return the address of a corresponding extended_type_info object.
In order to be used by the serialization library, an implementation of extended_type_info, (referred to as ETI here), must be derived from extended_type_info and also implement the following:
template
static extended_type_info &
static const extended_type_info &
Return a pointer to the instance of extended_type_info which corresponds to type T. Normally these instances are static objects so this just amounts to returning the address of this static object.
template
const extended_type_info *
ETI::get_derived_extended_type_info(const T & t) const;
Return a pointer to the extended_type_info instance that corresponds to the "true type" of the type T. The "true type" is the lowest type in the hierarchy of classes. The type T can always be cast to the "true type" with a static cast. Implemention of this function will vary among type id systems and sometimes will make presumptions about the type T than can be identified with a particular extended_type_info implementation.
bool ETI::less_than(const extended_type_info &rhs) const;
Compare this instance to another one using the same extended_type_info implementation.
The serialization library includes two distinct extended_type_info implementations.
is implemented in terms of the standard typeid(). It presumes that RTTI support is enabled by the compiler.
is implemented in a way that doesn't rely on the existence RTTI. However, if the export facility is to be used to serialize types through base class pointers, those types are required to implement a virtual function with the signature:
virtual const char * get_key();
which returns a unique string the most derived object this class. This function must be virtual in order to implement the functionality required by ETI::get_derived_extended_type_info as described above.
The test program test_no_rtti implements this function in terms of the extended_type_info API above to return the export key associated with the class. This requires that non-abstract types be exported. It also demostrates the inter-operability with between two different implementations of extended_type_info.

What is a Valedictorian?
If you're wondering what is the valedictorian definition, search no further. A Valedictorian is a title, often accompanied by an award and recognition, to high school and college students who give the final, farewell speech upon graduating from an educational institution. Almost always, a Valedictorian achieves the highest cumulative grade point average at their university.
The term "Valedictorian" comes from the Latin phrase, "vale dicere," which means, "to say farewell." A Valedictorian address is considered the final farewell it classmates at the education institution, and usually includes words of farewell, nostalgia, thanks, and inspiration. The Valedictorian speech is held at the graduation ceremony.
A school's valedictorian is almost always based upon the student who has the highest GPA at that education institution. This student is considered to be a representative of the class year they are graduating with. There can be exceptions to this, but the student with the highest GPA is almost always awarded the honorary valedictorian title. The exceptions to this rule are schools where multiple factors and extra-curricular activities are considered, such as speaking ability, extracurricular activities, participation level, and possibly selection from classmates. By and large, it's wholly or primarily based on grade point average.
In some cases, schools allow two valedictorians, sometimes called "co-valedictorians." This is usually done as a matter of affirmative action, school tradition, or some other exceptional or unusual reason.
Selecting a valedictorian can be a difficult and controversial decision for the school administration to make. This is because the difference in grade point average among the top students – potential valedictorians – is often minute. Some differ by hundreds of a percentage. Some cases are particularly controversial – when a student's GPA factors in weighted classes, for example.
Valedictorian addresses, typically called the valediction, is the farewell addressed that is given by the selected Valedictorian and a graduation ceremony. Typically, the graduation speech is inspirational, a persuasive speech, nostalgic, and sometimes even controversial or unconventional. Typically the valedictory is intended to inspire the students of the graduating class to go out and succeed in life, many times revolving around a central or class theme. The speech is also regarded to be the final farewell to the class as they move on to the "real world" and start their life.

I would like to change the following two graphs in this link here
Problem 1
Under the chemistry and physics tab I have a graph like this: enter image description here
Which is an agregate data set, but as you can tell the x-axis is not continuous nor is it chronological. How do I fix this?
Problem 2
On the dasboard tab I have this graph: g As well as having the same problem as the other graph, I would like to separate this one into physics and chemistry but I am unsure of how to do this.

For problem 1, you can add another tab then sort the data with =SORT
here's an old answer on stackoverflow
I update your sheet with a "data" tab.
With some combination of arrays you can regroup data to sort them and make some clean graphs.
I select the data i need between brackets to create an array {Chemistry!B3:C23;Chemistry!D3:E23}
Then i sort it by date here the column (1) and ask for an ascendant behavior TRUE
I now have all the data SORT({Chemistry!B3:C23;Chemistry!D3:E23},1,TRUE)
Same job for the physics' data.
To separate physics and chemistry on the same graph the easy way is to create an array with the date in common then add column physic and column chemistry side by side. Then you just retrieve data with a filter : FILTER($A$2:$B100,$A$2:$A100=E3)
I add an extra layer by creating another set of data to capture only workdays.
You can check the Dashboard tab and hide the data tab when you're done.

Usage
If you built forms with Symfony before, you'll really only need to check out the proposed conventions. Otherwise, you'll want to read through Symfony's documentation first.
Conventions
To keep things concise and clear, the following conventions should be applied in your project:
 - create your forms in App\Form,
 - have your forms end in Form (e.g., RegistrationForm),
 - create your form fields in App\Form\Field,
 - have your form fields end in Field (e.g., EmailField),
 - create your form constraints in App\Form\Constraint,
 - have your form fields end in Constraint (e.g., PasswordConstraint),
 - create your form validators in App\Form\Validator,
 - have your form fields end in Validator (e.g., CurrentUserPasswordValidator),
 - always register your forms as services.
This will significantly increase brevity for others. Especially, new developers.
Getting Started
First, let's see how a form can be built. For the sake of a relatable example, we'll focus on a registration form.
<?php
namespace App\Form;
use Passioneight\PimcoreForms\Form\Field\Checkbox\ConsentField;
use Passioneight\PimcoreForms\Form\Field\Text\EmailField;
use Passioneight\PimcoreForms\Form\Field\Text\RepeatedField\RepeatedPasswordField;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class RegistrationForm extends AbstractType
{
 const OPTION_TAC_HREF = 'tac-href';

 const FIELD_EMAIL = 'email';
 const FIELD_PASSWORD = 'password';
 const FIELD_ACCOUNT_CONSENT = 'account_consent';
 /**
 * @inheritDoc
 */
 public function buildForm(FormBuilderInterface $builder, array $options)
 {
 $builder
 ->add(self::FIELD_EMAIL, EmailField::class)
 ->add(self::FIELD_PASSWORD, RepeatedPasswordField::class)
 ->add(self::FIELD_ACCOUNT_CONSENT, ConsentField::class, [
 'label_translation_parameters' => [
 '{{ href }}' => $options[self::OPTION_TAC_HREF],
 '{{ href-class }}' => 'text-primary-hover'
 ],
 ])
 ->add('submit', SubmitType::class, [
 'label_format' => 'form.registration.submit'
 ]);
 }
 /**
 * @inheritDoc
 */
 public function configureOptions(OptionsResolver $resolver)
 {
 parent::configureOptions($resolver);
 $resolver->setRequired(self::OPTION_TAC_HREF);
 }
}
The RegistrationForm will have a single email field, a repeated password field, a checkbox for the user to agree to the terms and conditions of your service, and a submit button.
Note that the SubmitType is provided by Symfony itself. So, you can still use Symfony's types as you would usually.
The form will also require the developer to pass a URL for the terms and conditions when building the form.
Since the form is now implemented, it is ready to be used. For this, we'll have to create a controller with an action, which will handle the form's submission.
use App\Form\RegistrationForm;
use Pimcore\Controller\FrontendController;
use Pimcore\DataObject\Customer;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
 #[Route("/{_locale}")]
class AuthenticationController extends FrontendController
{
 #[Route("/{registration}")]
 public function registrationAction(Request $request)
 {
 $options = [
 RegistrationForm::OPTION_TAC_HREF => "/some/url/to/the/TACs"
 ];
 $registrationForm = $this
 ->createForm(RegistrationForm::class, new Customer(), $options)
 ->handleRequest($request);
 if ($registrationForm->isSubmitted()) {
 if($registrationForm->isValid()) {
 /** @var Customer $customer */
 $customer = $registrationForm->getData();
 // Omitted for brevity: handling the account consent

 $customer->save(['versionNote' => 'Customer registered']);

 // Omitted for brevity: sending confirmation mail(s)
 }
 }
 return $this->renderTemplate('authentication/registration.html.twig', [
 'registration_form' => $registrationForm->createView()
 ]);
 }
}
The getData method will return the submitted data, mapped to the fields. If mapping was disabled for a field (i.e., 'mapped' => false), the field has to be handled explicitly because the data is not available in the getData method.
The most common use case for this is any kind of consent.
