Whose Level of Service is the City Protecting? by Greg Hayes
Sometimes walking in San Francisco doesn't feel right. The urge to jaywalk and the quick analysis: when is the light going to change? Can I make it alive across these four lanes of speeding cars? The light finally changes, but it is not that easy. It is not uncommon that, thanks to the standard traffic engineering, pedestrians and bicyclists are forced to wait through two signal cycles in order to pass through one intersection. You start to suspect that pedestrian and bicycle movements are considered second class
Your suspicion is probably correct. The vast majority of the city's surface street space is judged by its ability to move motor vehicles, through the use of a rating system known as the Level of Service (LOS). This national standard measures the amount of automobile traffic a roadway can accommodate "without undue delay, hazard or restriction to the driver's freedom to maneuver."
The idea can be seen as something of a motor vehicle user's bill of rights, in which the driver's "freedom to maneuver" is the central concern. Basically, one type of citizen - a person driving a car - has more access to the public-right-of-way than any of its other users.
The LOS works like this: a roadway has a certain capacity of automobiles it can sustain before delay, hazard, and maneuvering ability are compromised to an unacceptable level. The successive stages of traffic dysfunction are assigned a letter rating which is set upon average delay time for cars. The best-case scenario is LOS A, with minimal delay times, etc. The worst is LOS F which indicates "forced flow" - basically the stage before total gridlock occurs. When roadways drop below failing level to LOS E, they fail the standard's appraisal, perhaps prompting a road widening, cutting the sidewalk back, or rejecting a proposed bike lane.
2 views of "forced flow" at the Panhandle to Golden Gate Park bike/pedestrian path.
Consider the double-crosswalk design of Stanyan and the Panhandle bikeway where ped/bike traffic seeking to enter the park is forced to wait through two separate light cycles just to maneuver though one intersection. The Golden Gate Park Master Plan and the San Francisco Bicycle Plan both call for a dedicated signal phase specifically designed to carry ped/bike traffic through the intersection in one movement. But the DPT hasn't allowed this for many years. Ask them why and they say because adding a new signal phase for the ped/bike traffic will make the intersection drop below failing LOS levels.
Here's where things really start to get twisted: what the traffic engineers are basically telling the people of San Francisco is that they cannot allow adequate pedestrian and bicycle facilities to be built because they will "cause congestion" and disturb the motor vehicle traffic flow that we are barely maintaining right now. The problem is one of abject, overt discrimination. Vast amounts of public time and space are appropriated and reserved for one mode of movement at the expense of all others. The LOS standard creates and perpetuates this situation and is constantly cited and invoked as means of denying pedestrian and bicycle facility improvements.
The SFBC will continue to advocate for an LOS-type measurement which actually takes other road users into account. After all, don't we all have the right to move down the street "without undue delay, hazard or restriction?" According to those in charge of our city's streets, apparently not.

To display an image in Laravel, you can follow these steps:
 1. Save the image in the public folder of your Laravel project. You can create a folder called 'images' in the public directory and save your images there.
 2. Use the asset() helper function in your blade template to display the image. For example, if you have an image called 'example.jpg' in the public/images folder, you can display it like this:
1

 1. Another way to display an image is by using the URL::asset() method. For example:
1

 1. You can also use the public_path() function to get the path to the public directory and concatenate it with the path to your image. For example:
1

By following these steps, you should be able to display images in your Laravel application easily.


ango command and then loading the extra user data from the ''admin_user'' fixture. At a later date, the ''manage.py createsuperuser'' command line utility can be used (as long as the extra user data for Astakos is added with a fixture or by hand).

108
Internal Astakos requests are handled using cookie-based django user sessions.
109

110
External systems in the same domain can delgate ''/login'' URI. The server, depending on its configuration will redirect to the appropriate login page. When done with logging in, the service's login URI should redirect to the URI provided with next, adding user and token parameters, which contain the email and token fields respectively.
111

120
====================== =========================
121

122
External systems outside the domain scope can acquire the user information by a cookie set identified by ASTAKOS_COOKIE_NAME setting.

How Does a Diverter Valve Work with a Turbo System?
How Does a Diverter Valve Work with a Turbo System?
How It Works 101
Driving a turbo car is a fun experience. The acceleration boost from the turbo is quite thrilling. Anyone who's driven or owns a turbo car will understand. But, did you ever wonder why a turbo makes an air release sound when releasing the gas? That sound is usually a blow-off or diverter valve. Per this article, the focus will be solely on the diverter valve concept. So, how does a diverter valve work with a turbo?
Breakdown of Diverter Valve Functionality
A diverter valve is a manifold vacuum-actuated valve that releases pressure into the intake system on turbo engines. This valve is also known as a compressor bypass valve (CBV) or a pressure relief valve. Furthermore, the valve release occurs during the lifting or closing of the throttle. Hence, while accelerating and then releasing the throttle, the car makes an air sound. This sound is the air pressure releasing into the intake. Many turbo enthusiasts love this sound, just as a supercharger fans enjoys the high-rev whining. By sending the air back into the intake, it overall benefits the performance of the vehicle. Even if it is only a slight boost in power, every bit counts.
Vroom! Hiss! Vroom! Hiss!
Euro Diverter Valves and DV+ Explained [GO FAST BRETT] – MCM TV2 – YouTube
Well, hopefully this article helps the reader understand the purpose of a diverter valve. Any vehicle with a turbo has some form of a blow-off valve. And, each one functions differently. Manufacturers such as Audi and VW use diverter valves in their vehicles. Furthermore, Aftermarket diverter valves are a great addition to a turbo vehicle. But, first, always ensure the valve fits the specific model. Buying the wrong valve may lead to lost time and longer wait periods. In conclusion, the diverter valve is a piece of technology that offers a way to be energy efficient.

Broadheads kill by cutting blood vessels, unlike the high-energy shock of bullets. Hemorrhage is typically the result. A responsible bowhunter will use razor-sharp broadheads and only take shots that allow a clear, close shot to the vital area of the game animal.
Many archers' injuries come from broadheads. Broadheads must be kept razor-sharp for hunting, which creates a safety problem if they are handled carelessly.
To prevent injury:
- Use a special wrench to screw on broadheads. This device covers the blades while a broadhead is being tightened on an arrow. If a wrench isn't used, the slightest slip can cause a serious cut. When sharpening broadheads, always stroke the blade away from your hands and body.
- Keep broadheads covered with a quiver while traveling to and from the field. Many arrow injuries occur while loading or unloading equipment in vehicles.
- While dressing bow-killed game, remember that the broadhead may remain in the animal. Use great caution until all parts of the broadhead have been found.

As the title says, I need to draw a shape/polygon in Farseer using debugview. I have this piece of code which converts a Texture to polygon:
//load texture that will represent the tray
 trayTexture = Content.Load("tray");
 //Create an array to hold the data from the texture
 uint[] data = new uint[trayTexture.Width * trayTexture.Height];
 //Transfer the texture data to the array
 //Find the vertices that makes up the outline of the shape in the texture
 Vertices verts = PolygonTools.CreatePolygon(data, trayTexture.Width, false);
 //Since it is a concave polygon, we need to partition it into several smaller convex polygons
 _list = BayazitDecomposer.ConvexPartition(verts);
 Vector2 vertScale = new Vector2(ConvertUnits.ToSimUnits(1));
 foreach (Vertices verti in _list)
 verti.Scale(ref vertScale);
 tray = BodyFactory.CreateCompoundPolygon(MyWorld, _list, 10);
Now in DebugView I guess I have to use "DrawShape" method which requires:
DrawShape(Fixture fixture, Transform xf, Color color)
My question is how can I get the variables needed for this method, namely Fixture and Transform?

Have you looked at the sample implementation of the DebugView? It draws shapes perfectly for me. – Vaughan Hilts Aug 5 '12 at 22:30

1 Answer
Have you tried the official documentation?
The getting started section shows how to create a fixture:
Fixture A fixture attaches (fix) the shape to the body so that the centroid of the shape becomes the body's position. Whenever you move the body, you also move the shape. Once a collision occur to the shape, the force is calculated and applied to the body.
Her is the code to create a World with a single body:
 1: //Create a World object with zero gravity
 2: World world = new World(Vector2.Zero);
 4: //We create a body object and make it dynamic (movable)
 5: Body myBody = world.CreateBody();
 6: myBody.BodyType = BodyType.Dynamic;
 8: //We create a circle shape with a radius of 0.5 meters
 9: CircleShape circleShape = new CircleShape(0.5f);
 11: //We fix the body and shape together using a Fixture object
 12: Fixture fixture = myBody.CreateFixture(circleShape);
You can also use the fixture factory
 Fixture fixture = FixtureFactory.CreateCircle(_world, 0.5f, 5, new Vector2(10, 0));
You can probably create a default transform (that doesn't transform anything) using:
Transfrom transform;
Note that you can also use the Box2D manuals, since Farseer offers the same features.

Hi Roy. Farseer documentation is just obsolete since it's made for version 2.X. FixtureFactory have been removed in Version 3, and another problem is I don't want a circle shape! I want my own custom shape which is made from the texture. – keyvan kazemi Apr 7 '12 at 16:49
It's true that the V3 docs are way basic, but I pulled this from them. I haven't installed Farseer, but have you looked at the other methods of the FixtureFactory, I'm sure there are more options :). – Roy T. Apr 7 '12 at 18:31

Definition - What does Supervening Cause mean?
A supervening cause is a cause of an injury, or of damage that comes after the initial set of events has already been put into place, but without which the harm could not have taken place.
In the context of the law, the person responsible for the supervening cause can be liable for the harm as opposed to the person who created the proximate cause.
Justipedia explains Supervening Cause
Often, there are multiple causes that go into harm being caused. For example, if a truck driver doesn't tie his load down and the products start spilling onto the highway, this could be a proximate cause. However, if a person behind the truck swerves unnecessarily far into oncoming traffic and causes an accident, this would be a supervening cause. In order to find out who would be fully liable for the damage caused by the accident, a court case would most likely have to ensue.

Brightly colored and ephemeral, Sulka ritual arts are created for one-time use in dances and ceremonies, during which their fleeting beauty allows the audience to briefly glimpse the divine. Afterward, the objects are destroyed. This work is a headdress worn on top of the head like a helmet. It portrays a praying mantis (kovio), possibly a clan emblem. Although its exact use is uncertain, it was probably a kapurei, a conical headdress that formed the base for a large ceremonial dance wand (rei) as much as nine feet (3 meters) high that was attached to the undecorated projection at the top.

Publicly Killable Computations
At our university department, people sometimes need to run expensive or long-term computations. We have few servers reserved for computations, but frequently it is useful to run computations on machines in the offices since some of them are fairly powerful and mostly get only very light use CPU-wise.
However, such computations must never impair any interactive or more pressing use of the machine. Therefore, we want to limit scheduling priority of the computations, limit total memory used by the computations and allow *anyone* kill *any* running computation. It turns out that this is not as trivial to achieve as I hoped.
In comes Computations under control: compctl – cgroup-based control of publicly limitable and stopable tasks. It is a tool that allows anyone to execute a command (or start screen) such that it is marked as a computation. Then, it allows anyone else to limit the total amount of memory allocated for all computations and to stop a specific computation or all computations on a machine. It uses cgroups to keep track of computations and limit the total memory usage, and a simple client-server architecture to perform priviledged tasks.
I hope it will be useful for someone else too. :-) Feel free to send in patches, and extra pairs of eyeballs checking the security would be welcome too. Top on my TODO list is simple debian package and a more verbose compctl –list output.

This hearty recipe is part of the traditional Acadian cuisine. It was – and still is – one of the favorite meals of Acadians, at least in the region of southeast New Brunswick.
Origin: Grand-Pré National Historic Site
Region: Atlantic (Nova Scotia)
Course: Main Course
Painting of The Harvest by artist Claude Picard© Parks Canada
Bouilli (boiled dinner) is a traditional Acadian meal. All of the ingredients would have been found in the bountiful gardens and farms of the Acadians in the area of Grand Pré. It was no doubt among the meals that the Acadian women prepared during the voyage from Grand-Pré to the Anglo-American colonies in the fall of 1755. In fact, the provision lists of the deportation boats included most of the ingredients – cabbage, turnips, potatoes and salt beef instead of salt pork.
- 5 oz | 150 g salt pork (cut in small cubes and sautéed until browned)
- 3-3½ lbs | 1.5 kg pork loin
- 1 lb | 500 g cabbage, cut in eight pieces
- 1 lb | 500 potatoes, peeled and cut in large chunks
- ½ lb | 250 g white turnip
- ½ lb | 250 g carrots, cut in 1-1½-inch (3-4 cm) pieces, then cut in half or quarters
- ½ lb | 250 g green or yellow beans (fresh or salted)
- In a large pot, cover the meat with water and bring to a boil. When almost cooked, add the vegetables beginning with the cabbage, carrots and turnips, then followed by potatoes and beans; bring all to a boil and cook until just done.
- The cabbage is usually cut into eight pieces, while the turnip is cut into round slices or half moons. Potatoes are cut into fairly large pieces, while the carrots are cut into 3 to 4 cm long pieces and split into two or four pieces depending on the size of the carrot. As for the beans, they are left intact, as is the pork. The pork tenderloin can be substituted with pork legs.
- Note: The original recipe uses salt pork instead of pork loin. If you choose to use salt pork and also salted beans, you will need to remove the salt before adding them to the other ingredients. To do this, cover the salt pork and salted beans with water and boil for about 10 minutes; drain and recover with fresh water. Repeat. Test the meat and beans; if still too salty, repeat a third time and then add to the rest of the ingredients.
- The quantity of vegetables − carrots, potatoes and beans − varies depending on taste. One large cabbage and one large turnip are usually sufficient, but more can be added if desired. Likewise more or less pork can be used.

When planning a North African-inspired party, it's important to keep these cultural traditions and culinary preferences in mind. By incorporating elements of North African culture into your celebration, you can create a festive and memorable event that honors this rich and diverse region.
Choosing the Right Venue
When it comes to planning a North African-inspired party, choosing the right venue is crucial to creating the perfect atmosphere. The venue you choose will depend on a variety of factors, including the number of guests, the theme of your party, and your budget.
Indoor vs. Outdoor
One of the first decisions you'll need to make is whether you want to have an indoor or outdoor party. If you live in a region with mild weather, an outdoor party can be a great option. Outdoor venues such as gardens, parks, or rooftops can provide a beautiful backdrop for your North African-inspired party. However, if the weather is unpredictable, or if you're planning your party during a time of year when it's likely to rain or snow, an indoor venue may be a better choice.
Whether you choose an indoor or outdoor venue, the decorations you choose will play a big role in creating the right atmosphere for your North African-inspired party. Consider incorporating traditional North African textiles such as Moroccan rugs, cushions, and tapestries. Rich, warm colors like red, orange, and gold will help to create a cozy and welcoming atmosphere. You can also incorporate North African-inspired patterns and motifs into your decorations, such as geometric shapes or intricate tilework.
The right lighting can make all the difference in creating the perfect atmosphere for your North African-inspired party. If you're hosting an outdoor party, consider stringing up fairy lights or lanterns to create a warm and inviting atmosphere. Indoors, you can use candles or dimmer switches to create a cozy and intimate atmosphere. Consider incorporating traditional Moroccan lamps or lanterns for an authentic touch.
Invitations and Guest List
When it comes to planning a North African-inspired party, the invitations and guest list are key elements that can make or break the event. Here are some tips to help you get it right:
Design and Theme
Your invitations should reflect the theme of the party and give your guests a taste of what to expect. Consider incorporating traditional North African motifs, such as geometric patterns, bright colors, and intricate designs. You can also add images of traditional North African food, music, or landmarks to create a sense of excitement and anticipation.
When designing your invitations, make sure to include all the necessary details, such as the date, time, location, dress code, and any special instructions. You can also include a brief description of the theme and what guests can expect to see, hear, and taste at the party.
Sending and Tracking RSVPs
Once you've designed your invitations, it's time to send them out and start tracking RSVPs. You can use online tools like Evite, Paperless Post, or Punchbowl to send digital invitations and track responses in real-time. Alternatively, you can send traditional paper invitations by mail or hand-deliver them to your guests.
Make sure to set a clear RSVP deadline and follow up with guests who haven't responded by that date. This will help you get an accurate headcount and plan accordingly for food, drinks, and seating arrangements.
|Include all necessary details
|Reflect the theme of the party
|Set a clear RSVP deadline
|Follow up with non-responders
With these tips, you can create stunning invitations and manage your guest list with ease, ensuring that your North African-inspired party is a festive and cultural celebration to remember.
Food and Drinks
One of the most important aspects of any party is the food and drinks, and a North African-inspired celebration is no exception. Here are some ideas for a menu that will transport your guests to the vibrant and flavorful world of North African cuisine:
North African-inspired Menu
Make sure to have plenty of vegetarian and gluten-free options available, as many North African dishes are naturally vegan and/or gluten-free.
Alcoholic and Non-Alcoholic Beverages
No party is complete without a selection of drinks. Here are some North African-inspired options:
- Moroccan mint tea
- Hibiscus iced tea
- Spiced hot chocolate
- Mango lassi
- Red wine from Morocco or Tunisia
- Arak or ouzo (anise-flavored liquors)
For non-alcoholic options, consider serving traditional North African drinks like mint tea and hibiscus iced tea, as well as refreshing fruit smoothies like mango lassi. Spiced hot chocolate is also a cozy and comforting option for cooler weather.
For alcoholic options, try serving red wine from Morocco or Tunisia, or anise-flavored liquors like arak or ouzo. These drinks pair well with the bold and flavorful spices found in North African cuisine.
Entertainment and Activities
One of the most important aspects of any party is the entertainment, and a North African-inspired celebration is no exception. Here are some ideas to get your guests moving and grooving:
Music and Dance
No North African party would be complete without traditional music and dance. Hire a live band or DJ to play authentic tunes and get everyone on the dance floor. Encourage guests to join in on the fun by providing instruments like drums and tambourines.
Henna Tattoo Artists
Henna tattoos are a beautiful and traditional form of body art in North African culture. Hire a henna tattoo artist to create intricate designs on your guests' hands and feet. Not only will it add to the cultural experience, but it will also give guests a unique souvenir to take home.
Belly Dancing Lessons
Belly dancing is a popular dance style in North Africa and the Middle East. Hire a professional belly dancer to teach guests some basic moves and get them involved in the performance. It's a fun and interactive way to keep the party going.
With these entertainment options, your North African-inspired party is sure to be a hit. Don't forget to capture the memories with a photo booth or photographer to document the festivities.
Hosting a North African-inspired party is a great way to celebrate the rich culture and traditions of this region. With the right planning and preparation, you can create a festive and memorable event that your guests will love.
Tips for a successful North African-inspired party

refreshing choice. Low carbonation beers help reduce the uncomfortable feeling of being overly full and can minimize discomfort during digestion. These beers are a great alternative option for individuals who are sensitive to high levels of carbonation or experience digestive issues after consuming regular beers.
The lower levels of carbonation in these beers result in a smoother, lighter mouthfeel, making them easier to enjoy without the worry of feeling bloated. Additionally, low carbonation beers often have a more subtle effervescence, allowing the flavors to shine through and providing a more balanced drinking experience.
So, if you're looking for a beer that won't leave you feeling excessively bloated, give low carbonation beers a try and discover a more comfortable way to enjoy your favorite brews.
Moderation and Balance: Key Principles for Digestion
Now, it's time to remember that finding the right balance and practicing moderation in your drinking habits is essential for maintaining a healthy digestive system. Understanding moderation means being aware of the amount of beer you consume and ensuring it aligns with your body's needs. It's important to strike a balance between enjoying your favorite beer and not overindulging. By maintaining balance, you can avoid the discomfort of bloating and other digestive issues that can arise from excessive drinking.
To help you visualize the concept of moderation and balance, here is a table that highlights the key principles:
|Limiting the quantity of beer consumed||Drinking in proportion to your body's tolerance||Reduces the risk of digestive problems|
|Taking breaks between drinks||Alternating alcoholic and non-alcoholic beverages||Promotes better digestion|
|Listening to your body's signals||Practicing mindful drinking||Enhances overall well-being|
By understanding moderation and maintaining balance, you can enjoy your beer while keeping your digestive system in optimal health. Cheers to a harmonious relationship with your favorite brew!
Frequently Asked Questions
Can drinking beer help with digestion issues like bloating and gas?
Drinking beer can potentially help with digestion issues like bloating and gas. Certain beers contain probiotics that promote a healthy gut microbiome, which can aid in digestion and alleviate symptoms. Explore the benefits of beer for gut health.
Are there any specific ingredients in beer that can negatively impact digestion?
Beer can have negative effects on gut health due to certain ingredients. Common digestive issues caused by beer consumption include bloating, gas, and heartburn. These ingredients can disrupt the balance of the gut microbiome, leading to digestive discomfort.
Is it true that light beers are easier to digest compared to other types of beer?
Light beers can be easier to digest compared to other types of beer. They have lower alcohol content, fewer calories, and less carbonation, which can all contribute to a smoother digestion process. Dark beers, on the other hand, may negatively affect digestion due to their higher alcohol content and richness in flavor.

Resumo
It was recently shown that, in general, the von Neumann spin entropy of fermionic particles is not invariant under Lorentz boosts. We show that an analogous result can be recovered (at the lowest order of v(2)/c(2)) using plain nonrelativistic quantum mechanics provided one uses that energy weighs: E = mc(2). This should (i) help to moderate the skepticism on the observer dependence of the spin entropy of fermionic particles, (ii) emphasize the soft relativistic nature of this result, and (iii) show that this is a particular case of a more general class of systems, since our calculation only assumes a nonrelativistic particle endowed with an internal degree of freedom.<bold> </bold>

Comments not showing on YouTube can take your video-viewing experience down a few notches. We use this section to gather all 'behind the scenes' information while others visit it to determine if the content is worth watching or not.
Regardless of the reason you scroll down to YouTube's comment section, it's safe to state they hold significant importance to the users. Unfortunately, this section is often inaccessible due to certain errors or glitches, particularly in the Chrome browser.
YouTube comments not loading is, in fact, among the most vexing matters users face on this entertainment website. On the brighter side, this article contains a step-by-step guide on how to fix it. So, if your YouTube comments won't load, here is what you need to do.
How To Fix YouTube Comments Not Loading?
One of the basic ways to enable YouTube comments is to run a rudimentary troubleshooting routine. Don't know how to do it? It's easy: just follow the below-mentioned steps.
Reload the entire page: Oftentimes, a simple reload can remove basic glitches on the page, thereby making the comments visible again.
Be patient: Maybe you're not at fault here. The bug could be on the other end of the table (from YouTube), and it may resolve itself after a few minutes.
Restart Your Router
If your YouTube comments don't load even after reloading the page or patiently waiting, then you may have an issue with your internet connection. To resolve this, restart your router by doing the following:
- Turn off your router through the dedicated switch on it (recommended), or remove its power cable. Note:
- Turn off your CPU (or your smartphone, if that's where the problem has occurred)
- Wait for a few minutes before restarting both the router and the CPU.
This drill usually works in the case of minor bugs, but if you still can't see comments on the YouTube app or desktop, then you'd have to dig deeper into the root cause.
Perform A Hard Refresh
Do not confuse this with formatting your device. Hard refresh means clearing your entire browsing data, cookies, and cache. These are bits of information that your device gathers to make your experience even more seamless. However, sometimes it backfires as the cache may hinder basic YouTube functionalities, including YouTube comments not showing.
Here is how to perform a hard refresh on Windows and Mac devices:
- Windows: Press the F5 and Control (Ctrl) button simultaneously to clean browsing data, cookies, and cache.
- Mac: Press Option, Command, and simultaneously to remove the abovementioned data.
Clear Browser Data
The constant accumulation of browser data is disruptive and sometimes interrupts your browsing or causes other technical issues, including the error "YouTube Comments not Showing."
In simple words, this means that you need to regularly delete this data which includes data history and cookies. You may do this by performing a hard refresh on your PC, which will reload the YouTube page and clear your browser data, or you can clear all of your browsing data.
Here is how to clear your browsing data on Windows and Mac devices:
From Chrome (Windows)
- Select 'Settings' from the three-dotted menu symbol in the top-right corner of the browser (next to the address bar).
- Click on 'Clear browsing data' after selecting 'privacy and security.'
- Choose whether you wish to erase the browser's data for the last 24 hours, seven days, the entire month, or All-Time from the Time range drop-down menu.
- Examine all of the browsing data options before pressing the Clear data button.
- Refresh the page and check if you see comments.
From Safari (Mac)
- Open Safari, click on 'safari', and then select 'preferences'.
- Select 'Advanced' from the bar and click on the box next to 'show develop in menu bar'.
- Select 'Empty caches' after clicking on 'develop' from the menu bar.
- Click on Safari from the menu bar to select 'clear history' to delete cookies and other browsing data.
- Click 'clear'.
Clear YouTube App Cache
If you have tried loading comments on your phone and they are still not showing up, you should try clearing the YouTube App cache as it is one of the most effective methods.
Here is how to clear App cache on android and IOS devices:
- Go to settings.
- Select 'Apps and notifications'.
- Press' YouTube'.
- Select storage, and from there, press on 'clear data' and 'clear cache'.
- Simply uninstall the app to clear all the App cache.
- Reset Chrome Setting
So you've discovered that a specific web browser is generating the "YouTube comments not showing" bug. After resetting your chrome settings, your web browser will revert back to its default settings.
This is a good troubleshooting option for a variety of issues that impair the browser's functionality and the performance of various websites.
Reset Chrome Settings On Windows And Mac?
From Chrome (windows)
- Select 'settings' from the drop-down menu after clicking on the three dots.
- Click 'reset and clean up' from 'advanced'.
- Choose 'Restore settings to their original defaults.'
- Click 'reset settings' in the new window pop-up.
From Safari (mac)
- Open Safari, click 'safari' from the menu bar, and click 'preferences'.
- Click 'manage website data' after selecting 'privacy'.
- Select 'remove all' and then select 'remove now'.
- Disable Adblocker/extension
Adblockers and other extensions sometimes interfere with elements of a website that could even include the YouTube comments not showing error.
With that information, we recommend that you disable any adblockers or extensions and reload YouTube to check if this is the problem.
Disabling Adblockers/Extensions On Windows And Mac
- Click the three dots on the upper right corner and hover over 'more tools'.
- Click extensions.
- Turn the switches off and reload YouTube to see if this was the cause.
- Open Safari, click 'safari' from the menu bar, and click 'preferences'.
- Click on 'extensions'.
- Uncheck the box next to all the extensions and reload YouTube to see if this was the cause.

- Select 'proxies' and deselect all the boxes under 'select a protocol to configure'.
- Click 'ok'.
Check Incognito Mode
When you use the incognito mode, there are no plugins used or browser data collected. This can help you solve your issue.
Here is how to use incognito mode on Windows, Mac, and the app:
- Press Ctrl, shift, and N buttons simultaneously.
- From Safari
- Press Command, shift, and N buttons simultaneously.
- Tap on your profile and select 'turn on incognito'.
- Try on a different browser
Sometimes chrome also malfunctions. Thus, using other browsers such as Firefox or Opera may be the solution to your problem. Try using other preinstalled browsers and see if YouTube comments are loading accurately.
Update Chrome Browser
Ensure that your browser is up to date. To update it, type 'chrome://settings/help' in the address bar and press enter. The browser will check the updates and ask you to download one if there are any. However, be sure to re-launch the browser.

National library week began in 1958 as a national observance of libraries across the country, sponsored by the American Library Association (ALA). It began in the mid-1950s after research showed that Americans were spending less time with books and more time on radios, televisions, and musical instruments. The ALA and the American Book Publishers responded by creating an organization in 1954 called the National Book Committee. By 1957 the committee developed a national plan for a library week hoping to encourage more people to read and thus support their local library. In 1959, the ALA voted National Library Week to be an annual celebration. In 1974, the ALA assumed full sponsorship of the annual event. Taking place each April, National Library week is a chance to celebrate all of the contributions that libraries and library staff have made in our nation while encouraging continued support for the library. During National Library week, libraries of all kind including public, academic, school and special collectively participate.
Within the each national library week, other celebrations take place that include, National Library Workers Day (usually celebrated on the Tuesday of national library week), National Bookmobile Day (celebrated the Wednesday of national library week), and Support Teen Literature Day, (celebrated on the Thursday of national library week).
As part of the Harper College Library's celebration of national library week, the library conducted Library Snapshot Day, 2011. Included are over thirty pictures that capture a typical day at the Harper College Library. Feel free to explore the different pictures taken of the Harper College Library by clicking on the picture you want to see for a larger image. Have fun exploring and we at the Harper College Library will see you later! –Nick Hyten, Harper College Library practicum student

Cockatiel vs Cockatoo - How To Tell Them Apart & Key Differences in Appearance, Size & Behavior
cockatoo vs cockateil featured image
Cockatiels are among the most popular pet birds in the world and are relatively easy to breed. These adorable little birds are often mistaken for cockatoos by most people.
If you fall into this category of people, then this article should give you a second thought…
...and maybe even a handy trivia fact or two to impress your friends.
There is a difference between cockatoos and cockatiels with the easily spotted one being their size. Cockatiels are smaller and known as miniature cockatoos.
More on this in a bit...
I'll even get into more details on the size, appearance, life span and other aspects where there is a difference to make things crystal clear.
Cockatoo and Cockatiel Bio Datalarge white cockatoo
Like you might have guessed, cockatoos and cockatiels are all under the same classification. Just like with English and American budgerigars (parakeets).
Specifically, they are all birds in the Cacatuidae family, with cockatiels being the only birds in the Nymphicus genera. And 'tiels are also the smallest in the family which consists of 21 birds.
As stated earlier, the first difference you will spot between an adult cockatoo and a cockatiel is their size. It's no surprise since they are the smallest among cockatoos, with sizes ranging from 12-13 inches.
Cockatiels are like babies when you compare their size to that of full-grown cockatoos which is between 12-24 inches. At this measurement, a cockatiel is only about a quarter or half the size of cockatoos.
But in the case a younger cockatoo hasn't reached its full size, you can know which is which by assessing their appearance...
yellow cockatiel
First off, the feather colors of cockatoos are most times solid or plain, with only a few patches of other colors. Most times, the predominant colors are either white or black while you may also find a gray or pink color on rare occasions.
On the flip side, cockatiels are brightly coloured and have different shades.
However, wild cockatiels are usually gray with patches of white on their wings and green or yellow on their tails.
But cockatiels kept in captivity have a color mutation that is on a whole new level compared to that of cockatoos or wild cockatiels. Some of them are white face pied, cinnamon pearl, pearl pied, and white face gray.
Another difference in appearance between a cockatoo and a cockatiel is their physique:
Cockatiels have a much smaller beak than cockatoos which is quite logical since they are smaller.
But cockatiels have a longer tail-type which makes up about half of their body, while the cockatoos have a shorter tail.
Cockatoos live longer than cockatiels in the wild or captivity. Some species, like the sulphur-crested cockatoo, can live longer than 100 years.
However, wild cockatiels only live for up to 25 years, and those in captivity live for an average of 14 years.
But they can reach 20+ years if they are well taken care of by their owners, as explained here.
large white cockatoo sitting on floor
In terms of personality, cockatoos are far more social than cockatiels and are more affectionate to their owners.
Unlike cockatiels, a cockatoo will need much more time out its cage with its owner and might become depressed if left alone for too long. But cockatiels, though good with people, can cope with being left alone.
Also, cockatoos are very noisy compared to cockatiels. I'll talk about that in detail in the next section.
In general, cockatiels are much calmer birds than cockatoos.
Vocal Ability
As said earlier, cockatoos are louder birds and also mimic their owner's words better than cockatiels.
'Tiels have a softer voice and make more bird sounds rather than talk. Even when they talk, their words are harder to understand than that of cockatoos.
On the other hand, cockatiels are more likely to imitate household sounds than cockatoos.
Of all the 21 species of cockatoos, cockatiels are easily the most popular pet bird.
Thanks to their small size and calm personality, they are easier to care which makes a great choice for both the old and young bird owner.
On the other hand, larger cockatoos are less common with the sulphur-crested cockatoo and umbrella cockatoo being the most popular among them.
two cockatiels perched together
Without a doubt, cockatoos are way more expensive than cockatiels.
'Toos are also more expensive to care for and shelter for than cockatiels because they are larger birds.
A cockatoo can cost from $1,000 to $25,000 depending on the species. Perhaps another reason why they are less popular as pet birds since they can cost a fortune. Plus, their cages need to be larger too.
On the other hand, cockatiels cost a more economical price of $80 to $250 compared to cockatoos. Their cages are smaller and more affordable as well.
Can A Cockatoo And A Cockatiel Be Kept Together?
Keeping a cockatoo and a cockatiel together isn't the best of ideas in my opinion.
Yes, they can stay together as long as the cockatoo isn't aggressive to the smaller bird.
But cockatoos can be territorial, which means that sooner or later, they might harm the cockatiel or even kill the other bird.
Wrapping Up
Hopefully you learned something new today about these wonderful parrots, whether their telltale appearance differences or drastically different prices.
What is your experience with 'tiels & 'toos? Let us know which one you have had as a pet in the comments below!

 - My mom and sister had an umbrella cockatoo (my sister still owns the bird, but she's moved out) and the hand raised him. He attacked my face when I was about 6, and he did it while I was sleeping on the couch (I think my room was being renovated at the time), and from what I heard from my mom, he also attacked my baby nephew. I still have a scar on my face to remind me why not to get a larger bird, especially unpredictable ones. My experience with 'tiels is very limited because the last one my parents owned was when I was maybe 4. I don't really have many memories of her, I just remember that she existed, and I'm getting my own 'tiel here soon

|Title:||ETYMO - An Interpreter to Simulate Historical Sound Change|
|Description:||ETYMO is an IBM-compatible program which simulates regular historical sound change. ETYMO works as an interpreter which first reads a set of linguistical rules that describe the diachronical evolution of a language. It then applies those rules to ancestor words (which can be single words or corpora containing an unlimited number of words) and calculates its descendency line or lines (the program can handle ''single'' and ''multiple'' evolutions - in the latter case, the different possibilities are represented in an evolution tree). For each evolution step, ETYMO can give detailed information about the transformation. All evolutions can be saved and printed out. When used for corpus calculations, ETYMO can give statistical information about the regularity of the evolution. A set of linguistical rules describing the evolution from latin to spanish is available.
The program has been developped as a diploma work (''ETYMO - un interpr?teur linguistique dans le domaine de la linguistique diachronique. Avec une application? l'?volution du latin? l'espagnol'') at the University of Fribourg (Switzerland).
The program, it's source code, the linguistical data (a corpus with 600 spanish words) and the written diploma work can be downloaded a _URL_

Ghosts of the Titanic dock at Shrewsbury library
By Doris Christelis, Contributing Writer
Shrewsbury – The Shrewsbury Public Library was recently transformed into a voyage on the Titanic for 80 lucky "passengers." Ticketholders holding "steerage" and "first class" tickets enjoyed a walking tour through the library, which had been transformed into different rooms of the Titanic in commemoration of Archaeology Month, which was October.
The tour, designed to educate and immerse the visitors in the Titanic's history, appealed to a broad range of adults and children who were able to step back in time to 1912.
"Since 2012 is the 100th anniversary of the sinking of the Titanic, a tour seemed a good fit," said Sharon Martin, Head of Children's Services at the Shrewsbury Public Library.
After entering the "ship," "passengers" were greeted by a model of the Titanic built by Dean Gillam, who also volunteered that night in the ship's boiler room. Tours led by Martin and Dan Barbour, the young adult librarian and volunteer coordinator, then proceeded past a model iceberg with photos of the real icebergs found in the vicinity of the ship's sinking. One of the icebergs had a smear of red paint on its base and it was thought that it was the one that the Titanic struck.
Throughout the tour, analogies to Shrewsbury were made. For example, while the library is 50 feet high, the 3,000-year-old iceberg that the Titanic struck was thought to be 50 to 100 feet high. "Passengers" also learned that the Titanic was as long as the distance between the library and the Town Hall, and that the last survivor of the Titanic, Lillian Asplund, died in Shrewsbury in 2006 at the age of 99.
In a room called "Titanic by the Numbers," "passengers" learned many interesting facts including how the ship that took three years to build sank in under three hours, and that three lap dogs survived, while so many passengers perished. Also interesting was that the hull of the Titanic was only three-quarter inch thick while most "passengers" in Shrewsbury guessed it was at least one foot thick.
Further along in the tour, "passengers" were able to visualize how big the average lifeboat was by tape marked out on a rug in the shape of a lifeboat. By putting the average number of passengers that had, in 1912, made their way onto one of the Titanic's lifeboats, visitors were able to visualize how much room remained on each lifeboat and could easily imagine how many more lives could have been saved had the boats been filled to capacity.
Other rooms with volunteers re-enacting members of Titanic's crew included the "Marconi Room" where wireless operators were the first to communicate that the Titanic was sinking to 25 ships in the area using Morse Code, including the Carpathia which was the first ship to respond although it was not the closest.
In the "ship's" dining room, visitors were able to dine on items from the Titanic's actual menu on the day of the sinking – chocolate éclairs that had been served in the first-class dining rooms, and "Cabin biscuits," a staple in steerage.
Those interested in more information on the Titanic are welcome to visit the Shrewsbury Public Library, where many books are available on the subject.

What is a Pay Code?
A pay code is a four digit code that allows you to identify one payroll from another. If you need to add a new pay code to your portal, please use the following pointers to help you create a pay code(s) that is useful to you.
A pay code
 1. Must contain four characters
 2. Must be alphanumeric (i.e. can contain only letters and/or numbers)
 3. Is case sensitive
If you need to add a payroll, then set the pay code to the next number in the sequence e.g. P00x.
 1. P001 for monthly payrolls
 2. P002 for weekly payrolls
 3. P003 for temporary/casual staff
 4. P004 for permanent staff
 5. P005 – office based in London
 6. P006 – office based in Manchester
You will need to input this code when setting up your payroll and uploading each payroll file.
The pay code is referred to in the NOW: File Format as the PAYCODE.

SilentMax® acoustic panels are also suitable for dance spaces. Thanks to its unique properties, it can improve the acoustics of the room so that the enjoyment not only of dancing, but also of listening to music is a real experience without unpleasant reverberation or echo.
The space of the H2B dance hall is 17.5 x 6.22 x 3.35 m. The total area of the hall is approximately 408 m2. The ceiling is supported by five lintels of 6.22 x 0.5 m, on which gray acoustic panels have been installed.
Measurement of the acoustic properties of the space
A calibrated UMIC microphone and REW software were used to measure the acoustic properties of the dance hall. The measurement was performed twice in total – before installation and after installation. What are the results?
Waterfall – reverberation time
It shows the intensity of acoustic energy depending on the frequency and reverberation time. The value of the acoustic energy in dB is represented by the Y-axis. The frequency from 100 Hz to 10 kHz is represented by the Y-axis. The time, or reverberation time, is represented in space by the Z-axis. In half a second, the Z-axis ends, at this border an area corresponding to the value of the acoustic energy in time 0.5 s.
RT60 – reverberation time
It represents the time in which the acoustic energy value drops by 60 dB. Time is represented by the Y axis. Frequency in the range of 100 Hz to 10 kHz is represented by the X axis. At a frequency of 1 kHz, after installing eight acoustic panels, the reverberation value dropped from 1.776 s to 1.025 s, which represents a 43% reduction in reverberation.
The installation of an acoustically absorbing surface with a total surface of 24 m2 reduced the reverberation by 43% (at an average frequency of 1 kHz). The echo was reduced by almost half. The intelligibility of the spoken word has fundamentally increased and the reverberation in the ballroom has been reduced. The music is more understandable, the individual musical instruments more concrete.

Formative Assessment, Homework, Self-regulation
This study explored the formative learning cycle's ability to increase student confidence to create quality homework. Student from a socio-economically diverse school district in Western Pennsylvania reported their confidence levels on homework production on two surveys. The first survey provided a rapid response at the end of lessons taught using the formative learning cycle. The second survey was completed at the end of the study window. The results from these surveys indicate a positive correlation between the formative learning cycle's ability to increase self-regulation processes to confidently produce quality homework.

This is Theorem of Three Perpendiculars, How to prove variation of it for N dimensional case (or to prove that it is false)?
Let $\mathbb{R}^N$ is N dimensional Euclidean space and $h_1, h_2$ are two intersecting hyperplanes (each has dimension N-1), $\mathbb{S}$ is intersection of hyperplanes $h_1$ and $h_2$. Let $x_1$ is a point at $h_1$, $x_2$ is an orthogonal projection of $x_1$ to the second hyperplane $h_2$, $x_1^p$ is an orthogonal projection of point $x_1$ to $\mathbb{S}$, $x_2^p$ is orthogonal projection of $x_2$ to $\mathbb{S}$.
How to prove that $x_1^p$ is equal $x_2^p$?
share|cite|improve this question
1 Answer 1
Okay, I write solution I have just found.
Hyperplane $h_1$ is $\{x| a_1^Tx +b_1 = 0\}$, for some vector $a_1$ and number $b_1$. Similar $h_2 = \{x| a_1^Tx + b_2 = 0\}$. Intersection set is defined as $\mathbb{S} = \{x|a_1^Tx +b_1 = 0, and\ a_1^Tx + b_2 = 0\}$.
Projection point $x_1^p$ is a solution of next optimization problem: $x_1^p = \arg\max ||x-x_1||^2,\ with\ respect\ to\ x\in\mathbb{S}$.
Similarly, $x_2^p = \arg\max ||x-x_2||^2,\ with\ respect\ to\ x\in\mathbb{S}$.
Because $x_2$ is a projection of $x_1$ in $h_2$, we have $x_2-x_1 = \alpha a_2$, where $\alpha$ is some scalar.
Next step is $||x - x_2||^2 = ||x - x_1 - \alpha a_2|| ^2 = ||x - x_1|| - 2((x - x_1)\cdot \alpha a_2) + ||\alpha a_2||^2 = ||x-x_1|| ^2 + const$, where we used that $x^Ta_2 = b_2$ because of the constraint set.
So, essentially optimization problems are the same, which means that points $x_1^p$ and $x_2^p$ coincide.
Do you like the proof?

ICU Processes and Procedures
ICU Release Version Number Policy
ICU version number consists of up to four digits separated by dot.
 - First two digits are used for major release number. Major release numbers for C and J are always synchronized.
 - Even number at the second digit indicates an official release (e.g. 4.2)
 - Odd number at the second digit indicates a development release (e.g. 4.3.1) for next major release.
 - Third digit in an official release number indicates a maintenance update which is applicable to both C and J.
 - Incremented only when C and J have common changes, such as CLDR update.
 - For example, CLDR 1.7.1 changes are integrated into ICU4C 4.2.1 and ICU4J 4.2.1.
 - Third digit in a development release number indicates a milestone
 - ICU4C 4.3.1 -> ICU4C 4.4 development milestone 1
 - Fourth digit in an official release number indicates a maintenance update only applicable to either C or J.
 - For example, ICU4C resolved some platform specific build issues and no equivalent changes in J.
Ticket Life Cycle
Here is a description of the life cycle of an ICU Trac ticket, a feature request or a bug report, from initial submittal through implementation and review to release.
Feature Proposals and Design
 1. All API design proposals (for any additions and changes) must be proposed on the icu-design mailing list.
 2. The proposal email itself must include: (See the template subpage)
 1. The proposed (new or changed) API signature(s)
 2. A Trac ticket number
 3. A Suggested API reviewer
 4. A deadline for comments (usually one week from proposal).
 3. Background information in the proposal can be helpful if the topic is complex. If there is a lot of information, write a design doc.
 4. The API signature must be reviewed by someone before submitting, and the reviewer must reply to the posting.
 5. In the ICU core team meeting, we have a regular agenda item to confirm recent API proposals (before or after code submission). Here we confirm that someone has reviewed it and no one objects.
 6. New/changed API that is discovered to not have proposal is withdrawn at or before the API Freeze milestone.
 7. We will try to write a tool to find API additions. The idea is to add a text file to the repository with expected additions/changes, and to check the actual set of APIs against that.
 8. There should not be major API additions after the API Slush milestone. Small additions (for example, new methods on existing classes) should be ok.
 9. Major functionality/new API or disruptive changes need to be implemented on a branch. The API there must be reviewed and confirmed before merging it to the trunk.
ICU Coding Style Guidelines
The ICU coding guidelines are described in the user guide at

Opening TRF file
No one can deny the dominance of Android devices in the smartphone market. About 88 percent of the world's smartphones are using the android platform. It is certain that you have a file with the apk. extension and having trouble on how to open it. You don't have to worry anymore since techshift provides us a comprehensive step-by-step visual guide on how to open a.APK file across different operating systems.
What is.APK?
The.APK file stands for Android Package. Google created the file format to share and install applications on Android devices. It is an executable file or in zip format, thus it cannot be read because it is compiled. However, it can be opened using 7 software on 4 platforms.
Here's the step-by-step guide by on how to open.APK file on Windows, Mac, Linux, and Android:
Opening.APK file on Windows OS
There are four simple steps on how to open a.apk file on Windows. Keep in mind that this will only work on Windows 7, 8, and 10
 1. You need to download specific software that can open the file like Google Android SDK, BlueStacks, Core WinZip, 7-Zip, and RARLAB WinRAR.
 2. Finding the original location of the file is the second step. You can usually find it in the /download/ folder.
 3. Once you found the file, perform a right-click on it and choose the "Open with" option.
 4. After clicking the "Open with" option, you will need to select the software you downloaded to open the.apk file (e.g. Google Android SDK). Click on the software and click "OK".
TRF format files may encounter problems
Opening.APK file on Mac OS
Like on Windows, there are also just four easy steps on how to open a.apk file on Mac OS.
 1. Downloading software that can open the file is also the first step here. On Mac OS, Google Android SDK and BlueStacks can be used too, but you can also download Apple Archive Utility.
 2. Locating the downloaded file is the second step. It is commonly found in the /download/ folder.
 3. Press right-click on the file and click the "Open with" option.
 4. Once you click "Open with", you should see the software you downloaded to open the file (let's say, in this case, we used Google Android SDK again). Choose the software and click on "OK".
In summary, opening an.apk file is not hard, there are just programs that you first need to install on your device in order to open the file. This may vary depending on the operating system you are using. For Windows, you can use Google Android SDK, BlueStacks, Corel WinZip, 7-Zip, RARLAB WinRAR programs. For Mac OS, you can download Google Android SDK, Apple Archive Utility, and BlueStacks programs. Only download Google Android SDK on Linux. Finally, for Android, simply install the Google Android software.


If you need to send money to Pakistan, then here is some helpful information – three (3) cheaper ways to send money to Pakistan from Australia.
Although there are multiple options, there are important factors to consider that can make a difference between one company or another when you are sending money to Pakistan.
How much money are you transferring?
The total amount you wish to send may influence on the best sending method. Traditionally, money transfer to Pakistan has been expensive so it is common to save a year's remittance and send it all in one go. That way you would pay a lower fee as you were sending only once.
However, nowadays with new mobile technology, sending money to Pakistan is free with some remittance providers, so there is no need to hold on to your money for a year and send it all in one go.
There is also an economic argument to send a smaller amount frequently.
Let me explain…
If you are familiar with the "time value of money" principle, you will agree with me that it is better to send the money in the present moment to Pakistan than keep it in your savings account. "$100.00 today is worth more than $100.00 tomorrow".
If you are not familiar with this phrase, let me clarify it for you. As the value of money changes over time, it is the concept that cash available at the present moment compounds in value and is therefore worth more than the same amount in the future.
Consequently, the funds will have a better impact on the recipient if sent in the current moment, rather than accumulating funds for one (1) more significant transaction in the future.
Providing that transaction costs are free, it is more beneficial to your recipient to receive multiple transfers to Pakistan in regular smaller amounts.
For example, if you have $100.00 today, with a nominal interest rate of 2%, it may be worth $102.00 a year later. A further year later, and your $100.00 has turned into $104.04.
How fast do you need the money in Pakistan?
The timing of the transfer of funds can be a big factor when sending money to Pakistan. Some transfers take days to finalise whilst others are completed instantly. Keep in mind that if your transfer is instant, your recipient does not have to wait hours or days for the funds.
You know they have received them straight away! Plus you also have peace-of-mind that the funds have not been lost which can be stressful! For this reason, the quicker the transfer, the better!
Consider also that the larger the transfer, the longer the transaction takes to complete. Depending on your provider, if you send less than 1,000.00 AUD, your recipient in Pakistan will typically receive the funds immediately. For amounts greater than 1,000.00 AUD, it is likely to take between 1 to 3 business days.
Which Receiving method do you prefer?
You will want to make it as easy as possible for your recipient to receive your remittance. One option is to use a method where they do not need to travel to access money such as electronic or digital remittance. Mobile money is a good solution here. More on this later.
While cash pickup is still a popular option, avoiding large sums of cash is sometimes preferred for safety and practical reasons. Non-cash remittance options also mean the recipient may not need to travel to make payments from the funds received. Plus electronic or digital remittance prevents the transmission of germs, among other things!
Reasons why you want to send money to Pakistan
If you are away from your loved ones, you may want to send cash as a gift or for a special occasion such as a wedding or anniversary. Or you may want to help family and friends for medical or education fees or to simply assist them with general expenses.
If you have a property in Pakistan and need to make mortgage payments, you may also need to make regular transfers.
Finally, you may simply want to make voluntary donations to charities or organisations or to assist people in Pakistan improve their circumstances.
3 Cheaper Ways to Send Money to Pakistan
One way to compare cheaper ways of sending money to Pakistan is by using an impartial, independent organisation such as the World Bank. Below is a comparison made by the World Bank, in which I have highlighted lowest price companies and methods for sending money to Pakistan. If you would like to check the full comparison directly visit the World Bank Remittance Prices page by clicking here.

Comparison Send Money to Pakistan
1. Mobile Money
Mobile money is a new technology that allows people to receive, store and spend money using a mobile phone. It is sometimes called a 'mobile wallet' or "digital money". There are more than 290 mobile money services around the world, although they are more common in Africa, Asia-Pacific and Latin America.
Mobile money is a popular alternative to both cash and banks because it is very simple and easy to use, can work on any mobile phone, is secure and can be used anywhere where there is mobile phone coverage.
These are a number of mobile wallet services you can use in Pakistan: EasyPaisa, JazzCash, Zong PayMax, Keenu Wallet, UBL Omni. They are simple to use, safe and you don't need an internet connection. Not all services support remittance. They are also a lower-cost way of receiving money in Pakistan.
How do I send money?
Sending to Pakistan using mobile money is usually done online and the transfer is instant. The recipient will receive a message when the funds are available in their account; it is as simple as that! The recipient does not have to travel anywhere to collect the money.
You can send money to Pakistan by SMS starting with the word PAY, followed by the mobile number of the recipient in the international format, followed by the amount in AUD, followed by their first name followed, by their last name followed, by their address. For more detail or for information on how to send money by SMS see FAQS
How does the recipient get my payment?
The overseas recipient must be registered with a compatible m-wallet or e-wallet operator in a supported country. Payments will be automatically credited to their m-wallet or e-wallet account. They will also receive a notification from their provider the moment they receive a payment from you (usually an SMS). They can access funds according to the services available to them from their m-wallet or e-wallet provider such as cash-out facilities at agents. See How It Works for more details.
2. Xpress Money – Send and collect cash
Although the world is moving to an electronic and digital age, a large group of people still prefer to do transactions in person using cash. Cash is still a popular remittance option for Pakistan. One operator who provides cash sending and pickup is Xpress Money.
Xpress Money allows you to send cash to Pakistan cheaply and easily. The sender must visit an Xpress Money agent in Australia and provide ID along with the cash. After handing over the money, you will receive a number that you must share with your beneficiary. Your beneficiary must then visit an agent in Pakistan to provide the code along with their ID and collect the cash.
Overall it is a simple service to use. It has low fees but as you may have noticed from my previous comments, cash management is not the most practical for larger amounts. Also, some agents may not have enough cash on hand if the amount is large. In the future, all our transactions will be likely to be digital, we may need to get used to it.
3. Bank in Australia to Bank in Pakistan
The above two options are useful for small transfers. Using a bank can be an alternative when you are transferring significant amounts of money. For example, when sending more than $5,000, using a bank transfer may be a more practical method.
The four major banks in Australia's all allow you to send money to Pakistan. Each of them has criteria that you must meet, including documents that you must supply and beneficiary information. The beneficiary must also have a bank account in Pakistan. See the links below for more information on each one.
– National Australia Bank
– Australia New Zealand Bank
– Commonwealth Bank of Australia
– Westpac Banking Corporation
Stick with me here, because…
I am going to explain the general criteria of how money transfer to Pakistan works using the banking system.
Before sending money, you should verify the personal details of the person who is going to receive the funds including their mobile phone number, full name as it appears on their bank account, and bank account details.
Regarding the account details, it is essential to include not only the account number and the name of the bank in Pakistan and the address, but also the swift code. Remember that these details have to be correct or your transaction may be rejected (and you may still be charged a fee!)
But wait, there's more…
Finally, after ensuring the above information is correct, check the exchange rate and make the transfer through the bank website. If you have entered the correct information after confirming the transfer, you generally cannot make any changes.
What is the exchange rate? It is simply the number of units that I need from one currency to buy a unit of another currency. Money exchange can be complicated and confusing. If you want to understand a little more how it works, read our blog 5 Reliable Australian Money Exchange Methods

This procedure determines the angle at which a bottle will tip and fall once the center of gravity has been overcome on tilting.
A tilt test device is fitted with the appropriate surface. The test device is then tipped until a test bottle breaks the plane of contact because the center of gravity of the bottle has been overcome. The angle at which this tipping occurs is considered the tilt angle. Typically, twelve bottles are tested and the average tilt angle is determined for the set of bottles.


Matching Socks in Dark Room
Problem
Matching Socks in Dark Room, problem
Solution
Let $f(n)$ be the number of pairings of $n$ pairs of socks into acceptable pairs. For $n\le 2$ any pairing is acceptable. Furthermore, $f(1)=1,$ $f(2)=3.$
In general, let's start we a sock of the darkest shade. If we happen to pick a sock of the same shade, we are left with computing $f(n-1).$ Otherwise, there is a pair of socks of the next shade; we can choose any of the two and match the other one with the remaining sock of the darkest shade. This gives a recurrence:
$f(n)=f(n-1)+2f(n-2).$
The characteristic equation of the latter is $x^2-x-2=0,$ with roots $x=2$ and $x=-1.$ The general solution of the recurrence depends on two constants: $f(n)=c_12^n+c_2(-1)^n$ which are found from the initial conditions $f(1)=1,$ $f(2)=3.$ Thus we arrive at
$\displaystyle f(n)=\frac{2^{n+1}+(-1)^n}{3}.$
For $10$ pairs of socks, there are $\displaystyle f(10)=\frac{2048+1}{3}=683$ possible matchings.
To find the sought probability, we have to find the total number of pairings, absent any restrictions.
One sock can be matched with any of $19$ but when that picked, the next sock may match with any of the remaining $17,$ and so on. Thus the total number of pairings is
$19!!=19\cdot 17\cdot 15\cdot\ldots\cdot 5\cdot 3\cdot 1.$
The probability we seek equals $\displaystyle \frac{683}{19!!}\approx 10^{-6}.$
An aside
$f(n)$ could have been found via generating functions. Let's set
$\displaystyle\begin{align}F(x)&=\sum_{n=1}^{\infty}f(n)x^n\\ &=1+3x+\sum_{n=3}^{\infty}f(n-1)+2\sum_{n-3}f(n-2)x^n\\ &=1+3x+x\left(F(x)-x\right)+2x^2F(x), \end{align}$
from which
$\displaystyle\begin{align}F(x)&=\frac{x+2x^2}{1-x-2x^2}=\frac{x}{3}\left(\frac{4}{1-2x}-\frac{1}{1+x}\right)\\ &=\frac{x}{3}\left(4\sum_{n=0}^{\infty}(2x)^n-\sum_{n=0}^{\infty}(-x)^n\right)\\ &=\frac{x}{3}\sum_{n=0}^{\infty}\left(2^{n+2}-(-1)^n\right)x^n\\ &=\sum_{n=0}^{\infty}\frac{2^{n+2}-(-1)^{n+2}}{3}x^{n+1}\\ &=\sum_{n=1}^{\infty}\frac{2^{n+1}+(-1)^{n}}{3}x^{n}. \end{align}$
By definition, $f(n)=[x^n]F(x),$ the coefficient of the series by the term $x^n.$ Thus, as before,
$\displaystyle f(n)=\frac{2^{n+1}+(-1)^n}{3}.$

Soldiers' and Sailors' Civil Relief Act of 1940
The Soldiers' and Sailors' Civil Relief Act of 1940
(SSCRA, or the Act) (50 USC 501) is a reenactment of a statute originally
passed in 1918. The intent of the Act is to provide protection for individuals
entering or called to active duty in the military service. The Act is designed
- Enable service members to fight a war without having to
worry about problems that might arise at home, and
- Help service members honor pre-service debts, since
military income tends to be less than pre-service income.
All members of the Army, Navy, Marine Corps, Air Force,
and Coast Guard on active duty and all officers of the Public Health Services
authorized for active duty with either the Army or Navy are covered under the
Act. The Act also covers members of the Army and Air National Guard and U.S.
military reserves called to active duty, as well as commissioned officers of
the National Oceanic and Atmospheric Administration on active duty.
The SSCRA covers such issues as rental agreements,
security deposits, prepaid rent, eviction, installment contracts, credit card
interest rates, mortgage interest rates, mortgage foreclosure, civil judicial
proceedings, and income tax payments. The following summarizes the relief
provisions that might affect financial institutions.
- Interest Rates. Under the SSCRA, service members
can cap the interest rates on all obligations that were entered into before
beginning active duty at 6 percent. Obligations include credit cards,
mortgages, and non-federally guaranteed student loans. In order to invoke the 6
percent cap, military members must write the lender requesting relief and
provide a copy of current military orders. In addition, service members must
demonstrate that active duty materially affects their ability to pay. The cap
is lifted a short time after active duty ends and the rate reverts to the rate
in effect prior to the cap.
- Mortgages. A lender may not foreclose on a
mortgage if the obligation originated prior to entry into active duty and the
service member's ability to pay is materially affected by military
- Installment Loans. A lender may not exercise any
right or option under the contract to terminate an installment contract to
purchase real or personal property or to assume possession of the property for
nonpayment, if the obligation originated prior to entry into active duty and
the service member's ability to pay is materially affected by military
- Leases. A service member may terminate without
penalty a lease for property occupied. The property must have been used for
dwelling, professional, business, or agricultural purposes. The service member
must have entered into the lease before he or she started active duty. To
terminate the lease, the member must provide written notice to the landlord
after called to active duty.
Contrary to what many people believe, there are no
provisions for reemployment rights as part of the SSCRA. Reemployment rights
are contained within separate legislation, The Uniformed Services Employment
and Reemployment Rights Act of 1994 (USERRA).

Optical coherence tomography (OCT) is a high resolution intravascular imaging method that allows visualization of flow diverter struts and the vessel wall. In this study, malapposition of the flow diverter that continues into the neck of the aneurysm, named communicating malapposition (CM), was investigated as a potential factor for delayed aneurysm healing.Methods
40 New Zealand White rabbits underwent elastase induced aneurysm creation, and were subsequently assigned to one of four treatment groups based on flow diverter type and administration of antiplatelet therapy. All animals underwent post device deployment balloon angioplasty and subsequent OCT to assess device/vessel apposition. The incidence of CM seen on OCT was assessed with a binary scoring system: 0–CM present; 1–CM absent. At 30 days, DSA was acquired to assess aneurysm healing. Aneurysm healing on terminal DSA was measured using a previously developed 5 point scale, with a score of 3 or 4 considered a positive outcome.Results
All animals were grouped into a single cohort for analysis as no difference in the rate of CM or healing was seen in the four treatment groups. Significant interaction between the absence of CM and a positive outcome was confirmed by Fisher exact test (P=0.0034). Angioplasty was shown to treat 33% of the cases of CM seen at implant, and these treated cases overwhelmingly had a positive outcome (P<0.001).Conclusion
The use of OCT to assess CM of flow diverters has been shown to be predictive of the 30 day healing rate of an animal model of aneurysms.
