When I connect my Desklab USB-C monitor [1] (which has been vastly underused for the last 3 years) into a Linux system the display type is listed as “DO NOT USE – RTK“. One of the more informative discussions of this was on Linux Mint forums [2] which revealed that it’s a mapping for an […] In 2008 I joined SAGE (the System Administrators’ Guild of Australia). It was a professional society for people doing sysadmin work (running computer servers). I quit when I found that the level of clue was lower than hoped and that members used the code of ethics as nothing but a way to score points in […] I had a problem with my mouse. The slippery plastic bits on the bottom weren’t glued on well and came off, which then gave more friction when moving on the desk. After asking advice on a mailing list the best suggestion was Teflon sticky tape. I bought a few meters of such tape (a lifetime […] I’ve just done a tech check for my LCA lecture. I had initially planned to do what I had done before and use my phone for recording audio and video and my PC for other stuff. The problem is that I wanted to get an external microphone going and plugging in a USB microphone turned […] The IBM i operating system on the AS/400 is a system that runs on PPC for “midrange” systems. I did a bit of reading about it after seeing an AS/400 on ebay for $300, if I had a lot more spare time and energy I might have put in a bid for that if it […] I’ve just started a Samsung tablet downloading a 770MB update, the description says: Overall stability of your device has been improved The security of your device has been improved Technically I have no doubt that both those claims are true and accurate. But according to common understanding of the English language I think […] The Situation I bought myself some USB microphones over ebay, I couldn’t see any with USB type A connectors (the original USB connectors) and bought ones with USB-C connectors. I thought it would be good to have microphones that could work with recent mobile phones and with PCs, because surely it wouldn’t be difficult to […] This page has summaries of some USB limits [1]. USB 2.0 has the longest cable segment limit of 5M (1.x, 3.x, and USB-C are all shorter), so USB 2.0 is what you want for long runs. The USB limit for daisy chained devices is 7 (including host and device), so that means a maximum of […] A client asked me to develop a system for “censoring” images from an automatic camera. The situation is that we have a camera taking regular photos from a fixed location which includes part of someone else’s property. So my client made a JPEG with some black rectangles in the sections that need to be covered. […] I’ve had a saga of getting 4K monitors to work well. My latest issue has been video playing, the dreaded mplayer error about the system being too slow. My previous post about 4K was about using DisplayPort to get more than 30Hz scan rate at 4K [1]. I now have a nice 60Hz scan rate […] |
