Scale background image of div to a fixed width; auto-scale height
Any reason you can't add <img src='base64'/> inside the div elements then in the css have div{background: 0px 0px} to hide the div background and have img{width:171px}? See the modified jsFiddle. That solves the problem, but not sure if you are able to add the img tag. Let me know and i'll see if another solution can be found.

Auto Generate Machine Key VS. Custom Machine Key
If you have a WebFarm you have to use custom machine key, other way it won't work. The only secure problem is that there are people, who knows these machine key. If they "sell it" outside your company somebody can for example decrypt your cookies.

Does windows azure virtual machine logs out when disconnecting
No, your Virtual Machines don't shut down when you disconnect from rdp/ssh. However: There's always the possibility that your machine will restart, even if infrequently (e.g. failed hardware, Host OS maintenance, etc.). So... your essential programs should be set up to auto-start at boot time, without requiring you to rdp/ssh in to start them up again.

Java synchronization is doing auto notify on exit ? Is this expected?
You shouldn't use a Thread object as a locking object. See more explanations in question Does java notify waiting threads implicitly?.

There is also another question linked from a comment, now I'll make it more achievable: who and when notify the thread.wait() when thread.join() is called?

I don't know if this is faster, but worth a shot My suggestion is to skip the eventlogreader class and go straight to WMI ( where you may be able to query just what you want.

How can I retrieve logs between two timeframes using regex?
Using bash, it is possible to generate a regex statement based only on two input timestamps, which you may pipe to a command (such as grep): #!/bin/bash #This is a bare-bone recursive script that accepts input of a start/end timeframe #in the 24-hour format, based on which a regex statement will be generated that will #select all values in between those two timeframes. Please note that this script #has undergone some optimization (I apologize for the reading difficulty, but it #did not occur to me until now that someone might have a use for such a script). #You are free to use, distribute, or modify this script to your heart's content. Any #constructive feedback is welcome. I did my best to eliminate all bugs, but should #you find any case where the generated regex is INCORRECT for som

Not able to retrieve call Logs specifically through blackberry 10
It turns out you can't do it in WebWorks, but you can add a native extension. I'm sorry that I can't provide you an example, but take a look at BlackBerry 10: Creating native extensions . From that page: Although a BlackBerry WebWorks application has a wide range of functionality, that functionality is limited to the resources that the application contains. By creating a custom extension, you can extend the functionality of your application to include the features and functions provided by core native APIs that are available to BlackBerry 10 OS applications. You create a custom extension in C/C++, which are the native languages for BlackBerry 10 OS, and then you wrap it in JavaScript. When you build and package your BlackBerry WebWorks application, you include the extension, so th

How to auto scale an image for all resolutions?
Regardless of the resolution your app still sees logical pixels of 800x480 (or 853 for 16:9), so your image size will not change. That article only talks about providing higher resolution images so that the images, when viewed on a higher res screen (which is often larger in size) is of better quality. In terms of layout and size though they will remain the same regardless of screen resolution. To test this add an image to your app and run it across multiple emulators with different sizes and you'll see that it stays the same relative size regardless of screen resolution.

Auto scale android resources
You could add the image you wish to use to the drawable-nodpi directory with an alternate name to it's drawable name. Then in drawable-ldpi create an alias to the drawable with the 'real' drawable name you wish to use using a drawable alias (http://developer.android.com/guide/topics/resources/providing-resources.html#AliasResources) Finally, in drawable-xhdpi create a scale drawable with the same 'real' name and a scale of 1, the source being the -nodpi counterpart (http://developer.android.com/guide/topics/resources/drawable-resource.html#Scale) This way, by preference, the scaling drawable should be used for ldpi-hdpi and xhdpi should prefer the fixed-scale drawable.

Sure, you can extract the current chart settings by calling chart.highcharts(), it contains each axis which will have the effective min and max as well as the data's min/max set based on the series that are using it. yAxis[0] would work if you only have one, but setting an id on the Axis might be clearer: var chart = highcharts({... yAxis: { id: 'my_y', ... yAxis = chart.highcharts().get('my_y'); yAxis.getExtremes(); // {min:, max:, dataMin:, dataMax:} yAxis.setExtremes(newmin, newmax); fiddle

Rotate and Scale with auto-layout in iOS6
The easiest way around this was to create the image programmatically using the following code to remove auto-layout. Since you cannot set image.translatesAutoresizingMaskIntoConstraints = YES if you add the image into the view using IB due to the apple "bug" with auto-layout. Because you will get an error saying, "Unable to simultaneously satisfy constraints" So you need to do this programmatically because IB adds constraints and you don't want any. UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(20, 20, 100, 100)]; image.image = [UIImage imageNamed:@"gorilla_red.png"]; image.translatesAutoresizingMaskIntoConstraints = YES; [self.view addSubview:image];

How to properly auto-scale AWS EC2 Instances group in a relatively complex infrastructures?
Auto-scaling creates new nodes based on the launch configuration. So you would have two separate auto scaling groups and two separate launch configurations. ie "VarnishScalingGroup" : { "Type" : "AWS::AutoScaling::AutoScalingGroup", "Properties" : { "LaunchConfigurationName" : {"Ref" : "VarnishLaunchConfiguration" }, "LoadBalancerNames" : {"Ref" : "ELB"}, ... } }, "VarnishLaunchConfiguration" : { "Type" : "AWS::AutoScaling::LaunchConfiguration", "Properties" : { ...

How can I replace CGAffineTransform scale and alpha animations using CABasicAnimations and Auto Layout?
I don't know why you want to do it with CABasicAnimation for scale. You can do it like you mention at the top of your question. Set a new value for the view's width and height constraint constant values and then use [myView layoutIfNeeded] inside animateWithDuration. If the view doesn't have height and width constraints, but has constants to the top and bottom and/or left and right edges of the superview, change those values instead.

Why does Cookie Session keep dying
It sounds like the cookie you get back from the server is a session cookie which, keeping it simple, means that when you stop the application and run it again the cookie is discarded. I would suggest to set on the server side a Max-Age or an Expire for the cookie. This should solve the problem. Another way to debug this kind of issues is to print out the HTTP Headers you get back from the server. There could be in fact a bug which does not set correctly the cookie expiration or Max-Age. Another really important thing is to set the Secure attribute of the cookie if you are using it to authenticate the HTTP clients/requests otherwise your cookie will be sent every and each time you execute an HTTP request to the domain specified in the cookie, even though the request is about a download o

git-svn clone dying with signal 6
Singal 6 is defined to be SIGABRT — this is a special signal which is sent to a process when it calls abort(3). In most cases the process does not handle this signal, and the standard disposition of this signal is to kill the process, which is what happens in your case. Supposedly the assertion checking code calls abort(3) in the end. As to the possible solutions, googling yields at least this as well as a number of other pointers — try to work through them.

Fibonacci Rabbits Dying After Arbitrary # of Months
This is copied from the answer in SpaceCadets question to help rbump it out of the "unanswered" list of questions. The two keys here were drawing out the tree to a large number, AND making sure to include a base case check for the first and second generations of deaths (It's -1 in both cases, and then it's something that depends on input). So 3 potential cases. The regular fib sequence when we don't need to account for deaths, the first and second generations of deaths to initialize our final sequence with the recurrence relation Fn-2 + Fn-1 - Fn-(monthsAlive+1) I'm certain there's a way to merge 1 or 2 of these checks and make the algorithm more efficient, but as of now it solved a large test case (90, 17) instantly and correctly. So I'm happy. Lesson learned: Use the entire white-b

A better way for a stacked area chart toggle between a percent scale and absolute scale?
So there are a lot of things you can do to avoid repeating yourself in the code. First of all a lot of the D3 functions you are using can be reused - they are general functions. This together with the concept of javascript closures means you only have to declare them once and initialize the parts that won't change. The stack layout does overwrite the y and y0 values, so to get the toggle to work I renamed your initial data to raw_x and raw_y and adjusted the accessors appropriately. Then the work of figuring out the yScale domain and actually updating the paths I wrapped into a function: function drawChart() { yScale.domain([0, d3.max(data, function (d) { return d3.max(d.values, function (d) { return d.y0 + d.y; }); })]); // new data items need t

How to retrieve specific columns rather than auto generate all columns or attributes from Entity
You are telling JPA to fetch Project and its referenced Employees, so it needs to return complete entities otherwise it corrupts the context. I don't know how/if Hibernate supports lazy basic mappings, but that might be one option - mark the attributes in Employee that you don't always want as lazy. This will affect both requestedBy and empNumber relationships equally though. If you do not want complete Employee data, you might have the query return only the data you want. Leave the query to fetch the empNumber but make the requestedBy relationship lazy, and have the query return Project and the Project_.requestedBy data that you want. Linda has a great example of using multiselect to return data at https://blogs.oracle.com/ldemichiel/entry/the_typing_of_criteria_queries .

Use NLP / Machine Learning to teach a machine how to detect if a string is mathematical?
Parsing is a better tool than machine learning for this problem. What you have described is a relatively simple grammar for arithmetic, with some aliases for numbers, and a touch of syntax for those aliases. A tokenizer and some basic syntactic analysis, which you could code directly, will produce better more reliable results with significantly less computational effort than machine learning and optimization will. One reason why parsing is sufficient is that you don't need to worry about misspellings as often as you do, say, with people's names. If you want to get fancy about that, then use your Jaro-Winkler-based things for lexical analysis and then use syntatic analysis on what you think are your tokens. That is still much cheaper and less complex than machine learning. I don't know mu

Reading from docs on MSDN: To run a single command on a remote computer, use the ComputerName parameter. To run a series of related commands that share data, use the New-PSSession cmdlet to create a PSSession (a persistent connection) on the remote computer, and then use the Session parameter of Invoke-Command to run the command in the PSSession. To run a command in a disconnected session, use the InDisconnectedSession parameter. To run a command in a background job, use the AsJob parameter. So basically you should do something like: $session = New-PSSession Invoke-Command -Session $session -FilePath <PathToScript>
