Home Assistant sensors

I finished migrating my VeraEdge to Home Assistant. I think after using it for some time, I find Home Assistant far superior to the VeraEdge in every way. So, I took the time to mostly standardise my sensors which make things simpler to manage/mantain. As such, essentially I am only using 4 types of sensors: ...

Supervisorui REDONE

Currently I am using docker containers to deploy applications. A number of those containers make use of supervisord for managing processes. While supervisord itself comes with a UI, it is unhandy for me because each container is its own supervisord instance. So I was interested in some software that would let me manage multiple supervisord instances in a single page. Turns out that there ...

Raspberry Pi Weekend project

So finally took the time to try out a Raspberry Pi. For this weekend project wanted to do something relatively simple. Essentially, I wanted to recreate/enhance the functionality of a TL-WR702N. The TL-WR702N Nano Router is a neat device but being closed, can not be customized to what I wanted. It can be used in the following modes: ...

Using a NAS200 as a Print server

Last weekend I had a small weekend project to move my All-In-One Printer/Scanner from my Xen host server to a spare NAS200 I had lying around. Since the NAS200 has a i486 compatible CPU, and I had been able to run a CentOS 5 distro before, I figure it would make a good server with low power consumption. For that I updated my NASCC firmware so that it would boot a USB key, and update my CentOS image creation script. This worked well, I was able to boot CentOS without that much effort altogether. I myself have an Epson Stylus CX5500 which unfortunately only comes with binary drivers. This was not much of a problem since the NAS200 has a i486 compatible CPU. I find this is relatively unique among different NAS models. Alas, the performance was quite disappointing. I should be used to the NAS200 underperforming. But really, this was truly sad. I did not bother to test the printing, but I did try scanning with it. Running scanimage to scan a single page was taking over 15 minutes before I hit Ctrl+C. It was an idea, but the results were so sub par. The only take-aways of this are: ...

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. ...

Askozia Desktop Appliance

So last weekend finally had some time to work with a Askozia Desktop Appliance. It actually arrived much earlier but without a Power Supply. Initially I though, "this is strange; I didn't know this supported PoE". (Power Over Ethernet). It turns out it didn't and there was a shipping mistake. After contacting the vendor, they sent me the required Power Supply. Overall I think the product is quite nice. It has a very nice User Interface that is quite easy to use. Simple configurations are indeed very easy to set-up. My feeling is that, as with any GUI, it usually trades user-friendly with expressiveness. So while I could configure most of the things I wanted from the UI, it did not support my home network topology fully. Initially, I had a DMZ vs Home-LAN configuration, with the Askozia box in the DMZ. Because the separation between the DMZ and the Home-LAN was through the router, it considered all the IP phones (in the Home-LAN) on the other side of the NAT, so things did not work properly. ...
