• PHP use function return value as array

  - by Richard Knop

  Why is it that this works: $cacheMatchesNotPlayed = $cache->load('externalData'); $cacheMatchesNotPlayed = $cacheMatchesNotPlayed['matchesNotPlayed']; But this doesn't work: $cacheMatchesNotPlayed = $cache->load('externalData')['matchesNotPlayed']; Is there some reason for it? The second bit is easier to write.

• How can I check for a file size and add that result in an Excel spreadsheet in Perl?

  - by Nano Taboada

  Currently I monitoring a particular file with a simple shell one-liner: filesize=$(ls -lah somefile | awk '{print $5}') I'm aware that Perl has some nice modules to deal with Excel files so the idea is to, let's say, run that check daily, perhaps with cron, and write the result on a spreadsheet for further statistical use.

• Create automatically only getters in Eclipse

  - by lerad

  In Eclipse is it possible to create automatically Getters and Setters for a field. But I have a lot of private fields for which only getters should exist. Is somewhere in Eclipse a "create Getters" Function which does not create setters too? Well, it is not so much work to write getters, but doing it automatically would be nice :) Thank you, lerad

• What's the difference between Render and RenderControl in WebControl creation?

  - by Michael Itzoe

  I've recently learned to write my own WebControls, but I'm still hazy on the difference between Render and RenderControl. I started out using Render, but at some point I started using RenderControl, which I now use exclusively. If I'm forming a bad habit I'd like to nip it in the bud now before I get set in my ways.

• Can I optimize this at all?

  - by Moshe

  I'm working on an iOS app and I'm using the following code for one of my tables to return the number of rows in a particular section: return [[kSettings arrayForKey:@"views"] count]; Is there any other way to write that line of code so that it is more memory efficient?

• Python stdout, \r progress bar and sshd with Putty not updating regularly

  - by Kyle MacFarlane

  I have a dead simple progress "bar" using something like the following: import sys from time import sleep current = 0 limit = 50 while current <= limit: sys.stdout.write('\rSynced %s/%s orders' % (current, limit)) current_order += 1 sleep(1) Works fine, except over ssh with Putty. Putty only updates every 3 minutes or if a line ends with \n. Is this a Putty setting, sshd_config, or can I code around it?
