Ergonomic keyboards

I have spent a large chunk of my life typing on a keyboard, but I did not start having tingling and pain in my hands until I also began using a smartphone. In other words, repetitive stress was not bad enough until my posture worsened as well. Or it was only a matter of time… so I started looking into ergonomic keyboards. In any case, I switched to the Microsoft Natural Ergonomic Keyboard but that only helped for a while. My right hand was especially a problem because of the mouse use. I even tried switching the mouse to my…

From a developer to a photographer

Ever had a blog and then did not write anything for five years? Here is how it happened in my case. Kids got bigger, got into volleyball, and one day I found myself trying to take pictures of fast moving subjects in badly lit gyms with no flash allowed. Phone cameras are not designed for that, and even a decent digital camera can not handle that situation with a kit lens (I had Canon Rebel T3i at the time.) After some research I got a Canon 70d with 85mm f/1.8 lens and that worked quite well for a while, but…

Please quit and relaunch Tunnelblick. If the problem persists, please reinstall Tunnelblick. It turned out that Verizon Wireless VZAccess tool I installed last night changed permissions of my /Applications folder so it is writable by any user. Tunnelblick makes sure that the folder(s) it is in do not have such lax permissions, so it would not connect until I did this: sudo chmod o-w /Applications Probably you would…

Download PECL Extensions for Windows

UPDATE: I removed my previous content from here because someone copy-pasted it into StackOverflow. Google “thought” I stole it from there and “accused” me of hosting scrapped content… StackOverflow removed the offending content as soon as I reported it, but I did not want to risk Google comparing my site to some cached version they may have, and it was all outdated anyway. The current state of affairs for downloading PECL extensions for Windows is still suprisingly bad. The only way I found (other than building your own) was to browse this list. Some of the extensions there will have…
