I just did a quick test of different compression options in Debian. The source file is a 1.1G MySQL dump file. The time is user CPU time on a i7-930 running under KVM, the compression programs may have different levels of optimisation for other CPU families. Facebook people designed the zstd compression system (here’s a […] PC hardware just keeps getting cheaper and faster. Now that so many people have been working from home the deficiencies of home PCs are becoming apparent. I’ll give Australian prices and URLs in this post, but I think that similar prices will be available everywhere that people read my blog. From MSY (parts list PDF […] In my last full-time position I managed the asset tracking database for my employer. It was one of those things that “someone” needed to do, and it seemed that only way that “someone” wouldn’t equate to “no-one” was for me to do it – which was ok. We used Snipe IT [1] to track the […] The Problem Video playback looks better with a higher scan rate. A lot of content that was designed for TV (EG almost all historical documentaries) is going to be 25Hz interlaced (UK and Australia) or 30Hz interlaced (US). If you view that on a low refresh rate progressive scan display (EG a modern display at […] One thing I should have learned before (but didn’t) and hope I’ve learned now is to photograph sysadmin work. If you work as a sysadmin you probably have a good phone, if you are going to run ssh from a phone or use a phone to read docs while in a server room with connectivity […] Just over a year ago I bought a Samsung Galaxy Note 2 [1]. About 3 months ago I noticed that some of the Ingress menus had burned in to the screen. Back in ancient computer times there were “screen saver” programs that blanked the screen to avoid this, then the “screen saver” programs transitioned to […] When I first started using computers a “word processor” was a program that edited text. The most common and affordable printers were dot-matrix and people who wanted good quality printing used daisy wheel printers. Text from a word processor was sent to a printer a letter at a time. The options for fancy printing were […] One problem I have had with my new Dell PowerEdge server/workstation [1] is that sound doesn’t work correctly. When I initially installed it things were OK but after installing a new monitor sound stopped working. The command “aplay -l” showed the following: **** List of PLAYBACK Hardware Devices **** card 0: Generic [HD-Audio Generic], device […] A client has recently asked for my advice on web editing software. There are lots of programs out there for editing web sites and according to a quick Google search there are free Windows programs to do most things that you would want to do. The first thing I’m wondering about is whether the best […] Chromium is the free software build of the Google Chrome web browser. It’s essentially the same as the Google code but will often be an older version, particularly when you get Chromium from Debian/Stable (or any other Linux distribution that doesn’t track the latest versions all the time) and compare it to getting Chrome straight […] |
