• Whats the maximum key length in NSDictionary?

  - by x3ro

  Hey there, I'm currently working on an app which displays a bunch of files in a table, and you can add and remove them and whatsoever. To prevent duplicates in the table, I'd like to create a NSDictionary using the files full path as keys for another NSDictionary which contains all the file information, but I am a little concerned about the maximum key length of NSDictionary, and also whether this solution would be performance killer or not... Looking forward to your answers. Best regards, x3ro

• What is mangling tinyurls?

  - by djn

  Hello all. I've noticed that some form processors make a mess out of posted TinyURLs (converting the thing to a broken 'tinyurl": "http:\/?\/?tinyurl.com\/?whatever", "ok": tr') while leaving alone other plain URLs. I've seen it happen in WordPress, and I've seen it here on SO (eg.: http://stackoverflow.com/questions/2508690/whats-the-most-efficient-way-to-setup-a-multi-lingual-website - second comment to first answer). Has anybody looked into what component or function is doing this? Is there a way to prevent it?

  - by JakiT

  I'm using Google Maps and have the map set to height/width=100%. I noticed that when I resize the browser window, my map marker icons appear to redraw on top of the same location. Meaning, if I should only have 1 map marker icon on "987 Main St", when I resize the browser window - multiple map marker icons are being now draw on top of "987 Main St" that shouldn't be there. Any ideas why this is happening and how to prevent it? UPDATE: Link to actual code

• Is it possible to run locally JRuby on Google App Engine without restarting server on every change?

  - by elado

  Unfortunately, GAE requires restart of the server on each code change. Is it possible to prevent it and have immediate feedback after code save? Or, can I import Google App Engine's API into my ruby code and run it on Sinatra server? Tried this but it fails on "import com.google.appengine.api" (it doesn't know what 'com' is). For Sinatra, I use "Rerun" ( http://github.com/alexch/rerun ) which restarts server immediately after a change with minimum wait. Thanks.

• prohibiting instantiation as a temporary object (C++)

  - by SuperElectric

  I like using sentry classes in c++, but I seem to have a mental affliction that results in repeatedly writing bugs like the following: { MySentryClass(arg); // ... other code } Needless to say, this fails because the sentry dies immediately after creation, rather than at the end of the scope, as intended. Is there some way to prevent MySentryClass from being instantiated as a temporary, so that the above code either fails to compile, or at least aborts with an error message at runtime?

• GCC how to block system calls within a program?

  Does anyone tell me how to block system calls within a program, please? I am building a system which takes a piece of C source code, compiles it with gcc and runs it. For security reasons, I need to prevent the compiled program from calling system calls. Is there any way to do it, from the source code level (e.g. stripping the header files of gcc, detecting malicious external calls, ...) to the executable level?
