Those fonts are not free. They may be just ttf files, but there is a massive amount of work that goes into creating a font with unicode support. If you just want fonts for basic compatibility, you can use open source fonts with compatible metrics such as the Liberation fonts or use the microsoft core fonts that haven’t been updated in 20 years.
You could also use a crystal for the ATtiny and get the same accuracy as the RTC. It should be accurate to about 20-30 seconds per month with a good crystal.
The internal oscillator only has an accuracy of around 1% after you calibrate it. It would be off by over 7 hours after a month. It’s also quite sensitive to voltage and temperature changes.
The drains in the 8205 MOSFET are connected together internally. In a DW01 circuit, they are not connected to anything else.
One MOSFET stops the battery from charging and the other stops it from discharging.
The hard drive should be connected by SATA or eSATA when making the image. Connecting over USB is just asking for more trouble when the drive is not working correctly.
I still get over 12 hours of web browsing or video playback with the backlight around 30% on mine even though my internal battery is down to 60% capacity and my external is around 90%. Standby drains about 10% overnight. I am running Linux Mint on mine and I set up TLP. Undervolting can increase the runtime quite a bit, but I haven’t bothered with that yet.
You could have a cronjob run something like find /home/user/.cache -type f -atime +30 -delete, which would find files that haven’t been accessed in the last 30 days and delete them. Make sure your home partition is not mounted with the noatime option though.
With the MATE screenshot tool, you can set a timer and set it to either capture the active window or the whole desktop. It will capture context menus when using the timer.
Many fonts have a license that allows them to be embedded in a pdf. Newer fonts usually have a flag that tells the software if the font can be embedded or not, not all software respects that flag though. Older fonts don’t have the flag and will embed even if you are not allowed to embed them.
That is strange that they would have size limit for the SSD. Maybe it only supports single sided M.2 drives, but if that’s the case, they should have just said it.
There are simple testers like this. It’s rather overpriced for what it is, but it would be trivial to make one yourself. That will only do a continuity check though. If you want to know what the current or speed ratings are, you will need to read the chip in the cable.
Timeshift works best if you use BTRFS for your root partition because snapshots can be taken instantly. I have mine setup to automatically take a snapshot every day.
Power consumption is the main issue. If it’s an old, power hungry desktop and you live somewhere with expensive electricity, it can be quite costly to run. If you have an energy efficient desktop or have cheap power then it will be fine. Just make sure it has a good quality power supply if it’s going to run 24/7.
I always shoot in raw+jpeg with the jpeg quality set to 100%. The raw files have a higher dynamic range and there is little or no processing done to them. The files are large, but storage space is cheap these days. The jpeg files are for convenience and if I don’t like the way they come out, I can process the raw file however I want and export it to whatever format is most suitable for what I’m using it for.
