After upgrade from 18.04 to 24.04, suspend stopped working on my MacPro 1,1 home server. I use it as a beautiful furniture/home server that sleeps unless accessed, so it being able to sleep is essential.
After lengthy diagnostics with Claude, the culprit was identified as Nvidia GT7300 video card, and the following script pasted to fix the issue:
Continue readingI was a long time Linux user, most recently using I3 (Ubuntu/Regolith). The moment Apple released M1-based laptop, though, I wanted one. Because it’s fast and deservedly so.
The article linked above talks about the M1 architecture and it’s hardware accelerators, which explains why any Linux kernel that would use that hardware platform to full potential is very far away, so it looks like the only way to enjoy it today is to live with macOS.
Moving to macOS from I3? Dock? Ugh. Poking with a mouse moving and resizing windows? Thanks, no thanks.
Can macOS be made to work more like I3? Yabai, Amethyst – not slick. Rectangle? Way too much bother. Could a third solution be found, satisfying the requirements, simple and easy to use, setup and maintain?
Continue readingAfter installing a Windows Remote Desktop client access licenses, commonly known as CALs, on an AWS EC2-based Windows machine, I made a mistake of not specifying my RD license server in the terminal server settings. Once the demo licenses ran out, the CALs did not take, and I ended up with a valuable machine, used by 4 people daily, locked out and impossible to login into.
Continue readingProblem – MacPro 1,1 is 32-bit EFI while having 64-bit architecture. There are other ways to boot that bypass EFI mode, but – booting in EFI mode on MacPro 1,1 allows for 2 more SATA ports (located on motherboard).
To run a live Ubuntu 18.04.1 USB on MacPro 1,1, one needs to add a 32-bit EFI boot loader, here is how to do it:
Xiaomi Mi Flora plant monitor is a cool high tech device for measuring plant’s soil moisture, and fertility, as well as light and temperature. The data is accessible via Bluetooth using the mobile app. The device is waterproof, the battery is said to last at least a year, and it costs about $17 on Amazon or Ebay.
NuHeat floor thermostats are great but have a couple of drawbacks: they cost a lot and they fail from electricity spikes. After two replacements, I decided that a cost of a NuHeat thermostat is sufficient budget for making something cool while not paying NuHeat for their extortive designs.
Most IoT devices communicate with servers on the Internet. How to ensure they are not used for malicious purposes by the manufacturer, government, or some random hacker?
I just overhauled my Rockshox Reverb seatpost, and found out how it works in the process. I own an X-Fusion Hilo too, so after I finished, I got curious and watched a video of its overhaul, so I now know how both seatposts work. In addition, I have a long-term perspective, as I rode each seatpost for about a year.
Crema is a foam comprising coffee oils, carbon dioxide created during coffee roasting and air trapped in coffee grounds. There are several exhaustive Coffeegeek articles in the subject. (I also think electric-pump-based coffee/espresso machines increase crema by aerating brewing water.)
Oils and bubbles, being lighter than water, travel up when brewing. When Aeropress is used as described in the manual, crema is filtered last and gets absorbed in the grounds and paper filter.
