Doesn't apply for USDT and USDC which can freeze funds with a court order.

And like the DAO hack on Ethereum showed, if most people who run blockchain software decide that something never happened, they can revert transactions that way.

Suppose the server only boots signed images created by itself, which the PXE server happens to serve. You cannot just switch or mess with the menu. But if you can exploit the boot chain before any Secure Boot components run, then you might find your way in.

After Brexit the tuition even for Europeans increased from 10K£ pounds a year to 40K£. A thousand pounds will not change much. It does of course change the kind of people they can admit from abroad, but it seems that the UK has a lot of demand. When I did an Erasmus MSc funded by the EU, I was the only European in the whole cohort. Many peers explicitly told me that they applied to get a chance to stay in Europe after they graduated. Most did.

Some of my friends insist on watching movies only in 4K, but once I secrectly played a proper 1080p BluRay copy and they would not believe it was 1080p.

Not much to do with the OP other than that it's been a long time since even the "tech-savy" have watched anything on disc. I guess 95% or more live with whatever potato bitrate they get from streaming services.

Remember that there are alternative playback clients which use Plex's backend. Infuse is one, but I think VLC also works. Both have Apple TV apps.

Anecdotally, this does work -- whenever I have had a break from nicotine pouches, I have done with cigarettes. The big difference is that with cigarettes you have to excuse yourself to go outside. It's much easier to break the habit this way. Though that might be in part how with nicotine pouches the act is different as well. Note that the nicotine content does go down this way -- I would say that the specific brand of cigarettes I roll are around 8mg in "Zyn" equivalent, which are usually sold in varying strengths from 3 to 12mg. Snus is a similar product sold usually at 8 to 24mg, though specific brands at 48mg exist.

The real challenge is that the difference between one cigarette a day and zero is huge, at least for me. Once you are at one cigarette a day, and e.g. commit to it being after a workday, you start waiting for the end of workday. It's easy to start feeling that the day does not begin until that moment. Real withdrawal starts at around day 3 and takes roughly 21 days for me.

I think smoking cessation products like patches and gum is not really helping either. It's still nicotine. I have wanted to try Varenicline, but it requires a doctor's prescription and (seemingly) "strong enough" dependence. I have hated the idea of paying 100 euros for a doctor's appointment to maybe get a prescription that costs me another 100 euros.

I plan to quit nicotine for good next month, when I submit a dissertation. After roughly 7 years of using snus and nicotine pouches, I have noticed that my gums are retracting, and when I eat food, a lot of it gets stuck at my lower teeth, and there are gaps between my teeth. I would not be surprised if I need braces, and in part wish that would solve the problem -- the gum retraction itself is irrecoverable. I have been waiting for a doctor's appointment to have my teeth checked out for about 6 months now. I can't help but think that in the process of doing my dissertation, I have trashed my health, at least to an extent, and now I'm just waiting to get an assessment how badly. Moving on, I think that whatever I'm about to do next, it should be something that I feel like needs no nicotine for motivation.

You most likely have this enabled and unless you run some ancient board. This UEFI mod is for motherboards from circa 2018. For workstation machines that would be 1st and 2nd generation Threadripper. So, if your CPU's model name starts with 3 or higher (and you have an AMD workstation), you likely have this already enabled by default.

Switching from macOS to Linux was quite painful because the security was so seamless on Mac. But I also realized I had no idea how my passwords are stored and under what guarantees. Learning and getting the hardware tokens to do it properly on Linux was a PITA. But reading this post made me feel a pinch better.

It indeed does, this is a very good point I haven't thought about in the reverse direction.

My anecdotal experience is that while LLMs are quite good at closing theorems given an LSP to inspect the proof-tree, they suffer from similar kind of problems with proofs as they do with bigger codebases in any language -- finding reusable parts that can be built into libraries (that's lemmas in Lean 4 sense). However, Buzzard has many times said that he wouldn't care how big the proof is and how ugly it would be, as long as there would be a proof.

SPIR-V states its an int, float, vector n (where n <= 4) or a matrix (2..4 cols of vector n).

It does not necessarily mean the hardware can do 4x4x64 floating point operations in a single subgroup operation, but at least the programming model supports framing it that way.

I've been writing a language around recursion schemes! Insofar it's just a library for Lean, but I wish to one day release it as an array programming language. I'm submitting a thesis in ~3 months, after which I'll be open-sourcing it.
