We did explore using standard protocols in order to support third party headsets. The most natural solution would be to listen for AT+BVRA (voice recognition command), which most headsets generate after some button is held down for a couple seconds.

Wget works pretty good for mirroring sites. Especially since version 1.18 which introduced support for img srcset parsing (unlike httrack, which unfortunately lacks that). The trouble with wget is that it doesn’t handle gzipped responses. (Which is IMHO quite surprising in 2017.) Wget always requests not compressed data with following: […]

Google Doodles. They seem cool but they may be distracting for some. Getting Doodles also isn’t free as they can be hundreds kB in size. There was no option to disable Doodles as they are core part of Google Chrome, the “newtab-serviceworker.js”. Luckily just recently, based on some planned changes (Chromium tracking bug 583292), […]

I switched to uBlock Origin from Adblock (Plus) when I had an issue with weird long loading times of some pages. I’m not sure if it was just a temporary issue with filters but switching to uBlock Origin helped. The uBlock benchmark also confirms that – that uBlock should be very […]

Just like as almost everyone else, I use rsync for updating backups. However the speed of sequential write on APU2 is only 40 MB/s tops, which is less than half the speed I can reach when copying using cp to external hard drive connected via USB 3. I can get […]

To be able to resize the root partition quickly, use LVM. The following part of kickstart configuration sets up 1 GB /boot (non-LVM) partition on /dev/sda1 and root partition on /dev/sda2 (LVM). Then anytime you increase the size of the disk (probably from some management of VM), just execute following on running […]

I configured my AIO router powered by CentOS using NetworkManager and firewalld as that’s the officially recommended way as of RHEL 7. Because I test various configurations, I also often restart services via “systemctl restart” to get back into safer state, eliminating runtime changes. I found issues when restarting firewalld or […]

The Mail.app on MacOS doesn’t delete emails immediately. It marks them with the deleted flag instead while keeping them in the folder until they are expunged – which happens for example when you quit Mail.app. This is standard way according to the IMAP RFC’s. It’s just that some other email clients […]
