Create A Map With Clickable Provinces/states Using SVG, HTML/CSS, ImageMap

Answer : jQuery plugin for decorating image maps (highlights, select areas, tooltips): http://www.outsharked.com/imagemapster/ Disclosure: I wrote it. Sounds like you want a simple imagemap, I'd recommend to not make it more complex than it needs to be. Here's an article on how to improve imagemaps with svg. It's very easy to do clickable regions in svg itself, just add some <a> elements around the shapes you want to have clickable. A couple of options if you need something more advanced: http://jqvmap.com/ http://jvectormap.com/ http://polymaps.org/ I think it's better to divide my answer to 2 parts: A -Create everything from scratch (using SVG, JavaScript, and HTML5): Create a new HTML5 page Create a new SVG file, each clickable area (province) should be a separate SVG Polygon in your SVG file, (I'm using Adobe Illustrator for creating SVG files but you can find many alternative software products too, for example Inkscape) Add mouseover and click events t

Create New Tmux Session From Inside A Tmux Session

Answer : The quickest way (assuming you use ctrl-b as your command prefix) is: ctrl-b :new To create a new session, then ctrl-b s to interactively select and attach to the session. How to create the script This script will check if a session exists. If session does not exist create new session and attach to it. If session does exist nothing happens and we attach to that session. Feel free to replace `~/development' with project name. $ touch ~/development && chmod +x ~/development # ~/development tmux has-session -t development if [ $? != 0 ] then tmux new-session -s development fi tmux attach -t development New session from terminal Let's create two detached sessions, list them, attach to one and then from within tmux cycle through sessions. tmux new -s name -d works from inside tmux because we're creating a new detached session. Otherwise you'll get a nesting error. $ tmux new -s development -d $ tmux new -s foo -d $ tmux ls > development: 1 w

Configuration Error: Missing Region In Config (AWS)

Answer : The correct code of Oregon region is us-west-2 .You have set it as us-west-2a in two places. While mentioning identity pool id,correct the code as below and try: AWS.config.update({region:'us-west-2'}); var myCredentials = new AWS.CognitoIdentityCredentials({ IdentityPoolId:'us-west-2:"Identity Pool ID"' }); If you are not passing the region for the API CognitoIdentityCredentials , then it will pull the data from AWS.config . Also, In your code, while initializing AWS.CONFIG with region name, You have used us-west-2a . Correct it, if you are going to use it instead of AWS.config.update . var myConfig = new AWS.Config({ credentials: myCredentials, region: 'us-west-2' }); Update I have identified another issue. The issue is that, you are initializing the AWS.config with var myConfig = new AWS.Config() but you are NOT updating the AWS.config class back with it. The missing code is : AWS.config = myConfig . As you are not updat

C# DataGridView Not Updated When Datasource Is Changed

Answer : Quick and dirty solution : dataGridView.DataSource = null; dataGridView.DataSource = phase3Results; Clean and correct solution : Use a BindingList<T> instead of List<T> as your DataSource. List<T> does not fire events when its collection changes. Also, if you additionally implement INotifyPropertyChanged for T , BindingList<T> automatically subscribes to property changes for each T in the collection and lets the view know about the change. Try using a BindingList<> instead of List<> and (as already suggested by Daniel), implement INotifyPropertyChanged. However, I think you can also call .Refesh() if you didn't want to implement the INotifyPropertyChanged interface. Here's an example ripped from here public class Car : INotifyPropertyChanged { private string _make; private string _model; private int _year; public event PropertyChangedEventHandler PropertyChanged; public Car(string make, string m

Calculating Difference Between Two Timestamps In Oracle In Milliseconds

Answer : When you subtract two variables of type TIMESTAMP , you get an INTERVAL DAY TO SECOND which includes a number of milliseconds and/or microseconds depending on the platform. If the database is running on Windows, systimestamp will generally have milliseconds. If the database is running on Unix, systimestamp will generally have microseconds. 1 select systimestamp - to_timestamp( '2012-07-23', 'yyyy-mm-dd' ) 2* from dual SQL> / SYSTIMESTAMP-TO_TIMESTAMP('2012-07-23','YYYY-MM-DD') --------------------------------------------------------------------------- +000000000 14:51:04.339000000 You can use the EXTRACT function to extract the individual elements of an INTERVAL DAY TO SECOND SQL> ed Wrote file afiedt.buf 1 select extract( day from diff ) days, 2 extract( hour from diff ) hours, 3 extract( minute from diff ) minutes, 4 extract( second from diff ) seconds 5 from (select systimes

Can CRC32 Be Used As A Hash Function?

Answer : CRC32 works very well as a hash algorithm. The whole point of a CRC is to hash a stream of bytes with as few collisions as possible. That said, there are a few points to consider: CRC's are not secure. For secure hashing you need a much more computationally expensive algorithm. For a simple bucket hasher, security is usually a non-issue. Different CRC flavors exist with different properties. Make sure you use the right algorithm, e.g. with hash polynomial 0x11EDC6F41 (CRC32C) which is the optimal general purpose choice. As a hashing speed/quality trade-off, the x86 CRC32 instruction is tough to beat. However, this instruction doesn't exist in older CPU's so beware of portability problems. ---- EDIT ---- Mark Adler provided a link to a useful article for hash evaluation by Bret Mulvey. Using the source code provided in the article, I ran the "bucket test" for both CRC32C and Jenkins96. These tables show the probability that a tru
