Yealink W52P

Yealink W52P So I was looking to replace my analog cordless phones mainly because I wanted to have a centralized way to maintain phonebooks. Right now I have two cordless phone that I have to manually enter phonebook entries on the two handsets independently. Initially I was thinking of getting small/cheap Android tablet and load it with a SIP soft phone. Trying with a couple of tablets I had was not very successful. On one hand my network topology did not work very well, on the other hand, the integration of the SIP soft phone with the directory and the other phone functions did not work as well as I expected. So when I came across the W52P, I was initially attracted to the low price. Grandstream had a cheaper phone, but it did not have remote phonebooks. After checking the documentation of the W52P, I confirmed that it did have a remote phonebook functionality. So bought it and tried it out. As a phone itself, it is about the same as the analog phones that it was replacing. The voice quality was pretty good. ...

Web Backups

As usual with any IT system backups are important. This does not change when using a free shared hosting provider. Because it is free, one would argue it is even more important. For my wordpress web site I used something called cli-exporter. It let's you create "Wordpress" export files from the command line so it can be run from cron. This is important because backups have to be automated. In addition to that, I copy the backup files to an off-site location. I do this by copying files using WebDAV to a storage provider. I did this by writing a simple script and using the PHP library SabreDAV which makes writing DAV clients quite easy. I myself don't mind using other people's Open Source code to do something. I was actually surprised that I was not able to find something that meet my criteria. However, thanks to the power of open source I was able to find something that fit the bill exactly. To make things more interesting, because I wanted to keep backup files as compressed Zip archives, my backup scripts did not work in one of the web hosts that I was using. They did not have the zip extensions enabled. This is surprising considering is quite standard. Luckily I was able to find a pure PHP library pclzip. ...
