All software has bugs. Modern “vanilla” distros aren’t especially buggy though. Install Mint or Ubuntu, if you need a network adapter make sure it supports Linux, then just use it like you would any other system.

Could you be more specific? What bugs have you found? What distros have you tried?

Losing weight and not sleeping face up may help in any case.

If you usually feel tired or sleepy during the day, it could be sleep apnea, which can have long term negative effects on your health. In that case, see a doctor, who will usually perform tests while you sleep and then may prescribe CPAP. If that doesn’t work or you find it too uncomfortable and the apnea is severe, you may be offered surgery.

There are some commercial devices that might help. Nasal strips are an option if you suspect your nasal passages could be compromised (deviated nasal septum). Chin straps and other devices that position your jaw do help in some cases wherein the issue is in your throat, especially when combined with CPAP.

Edit: also, don’t take medical advice from people on the internet ;)

As other commenters point out, not since the extinctionof Neanderthals, Denisovans, etc. But even if it were possible, the hybrid would not be fertile: our chromosome 2 is a fusion of two chromosomes that are separate in other related species, so there’s no way meiotic crossover recombination could possibly work.

I fully intend to go on with the project! Right now it’s not good enough to be interesting, but the results so far are too promising to not give it a chance.

Thank you! :)

I managed to get 4 piezo elements to work, limited by the FPGA. This was actually enough for some reasonable horizontal resolution since I used a phase array configuration, so the downside was the electronics had to generate very precisely timed pulses. The fourth prototype had 10 working elements thanks to replacing the MCU-FPGA duo with just a more powerful FPGA and using conductive glue to more reliably connect the elements themselves.

It was configurable to use any even divisor of 120 MHz, but in practice anything over 1 MHz would not even make it out of the acoustic lens due to the low voltage and low quality impedance matching layer. And much lower frequencies are barely useful anyways, so the true working range was narrow.

For the acoustic lens, I used the parametric design software OpenSCAD, with an equation for aberration-free lenses I had found somewhere and saved long before (will find it if you want) and the speed of sound in the different materials.

Well, one thing I’ve noticed in most measures that involve mental things (mood, performance…) is that lots of things seem to be cyclical. For example, mood is often alternating (more so in my case), but productivity and burnout also tend to repeat predictably as long as the routine doesn’t change.

Also, I’m maximally performant in tasks when most stable (good sleep, moderate mood, medication, no drugs…), but maximally productive when in a better mood.

Of course!

I wanted to test whether a cheap piezo buzzer could be used as a crude ultrasound probe. It worked, so I tried to upgrade it into full-blown ultrasound imaging. The third iteration of that did produce an image, using a piezo buzzer cut in sections, a cheap FPGA, a MCU, custom PCB and mostly 3D printed pieces (acoustic lens, etc.). Aside from the expected low resolution, turned out that it wouldn’t image anything beyond about 1 cm.

I did make a fourth iteration of the device, much smaller and theoretically much better. But life happened and I never finished the coding part.

I track lots of things, all the time; my body composition, performance at specific tasks… As for experiments, I’ve done a few:

• Tried to see if I could 3D print small channels and fill them with metal using electroplating (couldn’t).
• I also made a DIY ultrasound imaging device and tested it. Did actually produce some images, but it wouldn’t penetrate very far in tissues.

I mean China, Cuba, Laos, North Korea and Vietnam. It’s debatable whether they can be considered socialist, but they are usually given as examples of “failed” communism, so I felt it was important to note that’s not really the case, at least judging from the data.

I know it’s a joke, but current communist countries have the same average Human Development Index as current capitalist countries.

File trees 100 folders deep lol. I keep all stuff synced across my machines, no actual backup though…

I’d say !lemmy_support@lemmy.ml is the better option, but hey, as long as you got your question answered… :)

False in theory, true in practice. It is rare for the political landscape and a majority vote to align in such a way that it really has a disruptive effect. And in those instances wherein it happened, wasn’t uncommon to see a coup afterwards.

I don’t really think the Russian economy is any real bottleneck here; they have abundant natural resources, a densely-knit industry and even now still many trading partners. Ultimately the only realistic way to stop the war is a peace agreement, which is why people voted for Zelenskyy in the first place.

There’s this post of mine, also this article gives some background on the application of PIR to anonymous messaging. Basically, I’m trying to do a basic version of that, but using a state-of-the-art PIR protocol introduced in this article. It’s still not great performance-wise, but it’s enough to be practical (as stated, many thousands of users given enough resources).

No, sorry, I haven’t uploaded anything yet, I’ve only coded the protocols and some benchmark code. The idea is for each client to send and receive data continuously. Since text messages are pretty small and YPIR+SP doesn’t have a lot of overhead, that could be a reasonable way to conceal all metadata, as long as there are not enough people connected to overwhelm the server.

Human embryos do have immature gills, but they are reused to create ears, jaw, tonsils, thymus, parathyroids and the large arteries in the neck and upper chest. We could add extra pairs and try to turn them into actual gills, although that would require removing the aortic arch and forcing all blood through the gills. Connecting them to the pulmonary system is not possible, as lungs and gills need different pressures (that’s the whole reason we have two circuits). Maybe we could connect them in parallel to the aorta? That would only work as a backup, but with an adequate vasomotor system could do a nice job!

Sorry! I meant Private Information Retrieval, that could allow metadata-hiding messaging.

Depends a lot on where you live. In many countries, communism is simply considered “radical/violent” rather than “authoritarian”, and one is not considered a leftist of any sort unless they defend a leftist stance on the economy (progressive views on social issues may not be described as leftist everywhere).
