random PC tips

UPDATE: Focusrite have released a new version of their driver , which is compatible with all the 1st-generation Scarlett devices. So there is no need to install old drivers anymore! Recently I got a used Focusrite Scarlett 2i4 (1st gen) and I was very pleased with the sound and feel of it from the start. First thing to do was to download the driver from Focusrite's official page . Their drivers still work for Windows 10, although not officially supported. Then I plugged it in, and... It didn't work. I had plugged it to a blue USB 3.0 port. After trying one of the black USB 2.0 ports, it worked fine. And it sounds very nice! Unfortunately, not long after I got it my Windows 10 PC started bluescreening once a week. After a bit of wondering I realized the issue: The USB cable I used must be an old USB 1.0 cable, while the Scarlett 2i4 is a USB 2.0 device! After changing the cable to a USB 2.0 one I never had a bluescreen again. And, probably the Scarlett 2i4 also work...

Today, while updating my Ubuntu headless server, I got some errors from the mirror I was using: sudo apt-get update Err:1 http://fi.archive.ubuntu.com/ubuntu xenial InRelease Cannot initiate the connection to fi.archive.ubuntu.com:80 connect (101: Network is unreachable)  ...and so on. Seems there is some problem with fi.archive.ubuntu.com, or maybe they stopped serving updates for my old LTS version of Ubuntu. This was solved with some editing of /etc/apt/sources.list sudo nano /etc/apt/sources.list I replaced http://fi.archive.ubuntu.com/ubuntu/ with mirror://mirrors.ubuntu.com/mirrors.txt. If you want to be sure, leave the old lines there commented with #, so you can go back if this doesn't help. So the lines would look like this now: deb mirror://mirrors.ubuntu.com/mirrors.txt xenial main restricted  # deb http://fi.archive.ubuntu.com/ubuntu/ xenial main restricted  deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-updates main restricted # deb ...
