  - by tarnfeld

  For some odd reason the part where objects are shown and hidden in my script doesn't seem to be working. I'm not sure if its the fact firefox doesn't like that or whether its the function-based code I have (to save duplicating lines of code)? There is a working example here and the javascript is here All help appreciated

• Is there a better way to select tables based on how many rows they have via jQuery?

  - by bubbahotep

  I'm looking to grab a group of tables that have more than X rows with jQuery. Currently, I'm doing something similar to: $("table").each(function(){ if($(this).find("tr").length > x){ tableArray[tableArray.length] = $(this); } }); and then acting on the members of the tableArray. Is there a better way of getting these tables, perhaps a nice selector I've missed? Thanks

• JSON.parse vs. eval()

  My Spider Sense warns me that using eval() to parse incoming JSON is a bad idea. I'm just wondering if JSON.parse() - which I assume is a part of JavaScript and not a browser-specific function - is more secure.

• Do the changes to cpumask using sched_setaffinity() take place immediately

  - by Sukanto

  I am writing a linux kernel module that needs to pin two threads on two different cpus. I am planning to use sched_setaffinity() after exporting it in the kernel. Is there any other exported function for the same ? Also, if I set only 1 CPU in the cpumask, will the thread be moved to that cpu with immediate effect ? If not, how do I enforce the same ? Will it help to call schedule() just after sched_setaffinity() ?

• Obtaining standard port for arbitrary protocols in PHP

  - by Trott

  I'm looking for a function that will accept a string representing the scheme portion of a URL (e.g., "http", "https", "ftp", etc.) and return the standard port. It might be used like this: echo get_port_from_protocol("http"); // 80 As a last resort, I suppose I could write something to parse through /etc/services (assuming I only need to run under UNIX-like operating systems). But surely there must be something built-in to PHP, no?

• A question about c/c++ syntax

  - by user198729

  I don't have the c++ environment yet right now. It seems to me that a function must be declared/defined first to be called in c. I mean, the declared/defined part should be ahead of the calling part. Is it the same in c++? Finally, it seems c++ is adding new features to itself, what about c, has it stopped being developed?

• why doesn't focus() work in the following line of jquery?

  - by jela

  The following code is intended to check if 4 numbers are entered in the blurred field. If not, the field value is deleted, and the field is focused. The deletion works fine, but the the call to focus() does not work. $('input.dateValue').live('blur',function(event){ if (!(/(\d){4}$/.test($(this).attr('value')))) $(this).attr('value','').focus(); }); Why does the call to focus() not focus the field?

• Suspend orientation change

  - by OkyDokyman

  Documentation says: "a configuration change (such as a change in screen orientation, language, input devices, etc) will cause your current activity to be destroyed, going through the normal activity lifecycle process of onPause(), onStop(), and onDestroy()." I would like to suspend the orientation change, since it crashes my app if it was done in the middle of a a loop (of reading a file). How can I do this? Also - looking for some kind of "onOrientationChnage" function :)

• Javascript Date: Ensure getMinutes(), getHours(), getSeconds() puts 0 in front if necessary

  - by Mega Matt

  Hi all, Looking for a creative way to be sure values that come from the getHours, getMinutes, and getSeconds() method for the javascript Date object return "06" instead of 6 (for example). Are there any parameters that I don't know about? Obviously I could write a function that does it by checking the length and prepending a "0" if need be, but I thought there might be something more streamlined than that. Thanks.
