Binary Data in JSON String. Something better than Base64
... bytes as five characters. However, this is only a 7% improvement over base64, it's more expensive to compute, and implementations are less common than for base64 so it's probably not a win.
You could also simply map every input byte to the corresponding character in U+0000-U+00FF, then do the mini...
How to maintain aspect ratio using HTML IMG tag
...hoto in our application. I have set both its height and width attribute to 64. I need to show any image resolution (e.g. 256x256, 1024x768, 500x400, 205x246, etc.) as 64x64. But by setting the height and width attributes of an img tag to 64, it's not maintaining the aspect ratio, so the image looks ...
Should I use Python 32bit or Python 64bit
I have a win7 64bit installation. Must I use Python 64bit? What are the differences between the 32bit and 64bit Python versions anyway? Do different Python packages (such as south, django, mysqldb etc) support only 32bit/64bit?

...ing combinations of OS, JDK and Eclipse bitness. In my case, I was using a 64-bit JDK with a 32-bit Eclipse on a 64-bit OS. After downgrading the JDK to 32-bit, Eclipse started working.
Use one of the following combinations.
32-bit OS, 32-bit JDK, 32-bit Eclipse (32-bit only)
64-bit OS, 32-bit JD...

How do RVM and rbenv actually work?
... Similarly, the rbenv global command modifies the ~/.rbenv/version file.)
Armed with an RBENV_VERSION environment variable, rbenv adds ~/.rbenv/versions/$RBENV_VERSION/bin to the front of your PATH, then execs the command and arguments passed to rbenv exec. Voila!
For a thorough look at exactly wh...
What does the Visual Studio “Any CPU” target mean?
...
An AnyCPU assembly will JIT to 64-bit code when loaded into a 64-bit process and 32 bit when loaded into a 32-bit process.
By limiting the CPU you would be saying: There is something being used by the assembly (something likely
unmanaged) that requires 3...
