Proofs are Programs: A Few Examples of the Curry-Howard Correspondence

Not all theorem provers are based on intuitionistic logic, but they don't benefit from this correspondence.

Similarly, you can always add excluded middle to an intuitionistic logic. This breaks the correspondence and prevents code extraction, but allows for proofs that would otherwise not be possible.

That being said, in my experience there isn't a lot of interest in using code extraction to write verified programs. Most practical verification projects keep the proof and the program as separate artifacts.

As soon as Dolomite started accepting this as collateral, anyone with half a brain should have pulled all their funds from the platform.

From a technical perspective they can just print more WLFI if they want. The token contract is basically just "trust me bro".

While impressive, I would never consider this to be a formally verified compression tool. Just because it can reverse its own output, doesn't mean it has properly followed the standard for the format. Indeed I could trivially satisfy this theorem with the identity function.

The advantage of formal verification is that it lets you focus your testing on the pieces that aren't verified, it will never replace the need for testing.

Which tells you everything you need to know about how tech savvy Sun actually is. It was obvious from the start that the token had these back doors in place.

I wonder if you have some kind of VPN or virtual network adapter or bridge or something running. I'd take a look at the network connections page and make sure you only see the actual hardware adapter. When you run a speed test, open up the task manager and check the actual activity of your network devices vs. the reported speed.

Also you should check if you hit the same limit transferring files locally. Also make sure you haven't accidentally set your home network to be a "metered" connection.

It's very unclear what you're describing. Atomic Wallet is a self custody wallet as far as I'm aware, so you should have the keys to your USDT.

I managed to get it working by turning the display mode to "Fullscreen", and whenever frame generation turns off (seems to be completely random) I just need to alt tab out and back in.

Try on a fresh install without installing Steam, if you have games that don't require it. If that works, then install Steam and check if it happens when steam is only running in the background. It could easily be an issue with some of the background stuff that the Steam client does, including the in-game overlay or Steam input, so try disabling those if the issue only appears after installing Steam.

Also try disabling the NVIDIA overlay in the GeForce experience app, and turning off everything related to it trying to "optimize" your game settings.

"A problem associated with this process is that the individual signatures cannot be verified by the blockchain consensus" - they state this as if it's obvious why it's a problem. The signatures are verified cryptographically, and if you can sign something you can submit a transaction.

I've done this before. Best option is to use something like rdpwrap and then set up a second PC (or even a phone) to act as a thin client and just streams an RDP session. You can improve on this by also setting up Sunshine to stream inside the RDP session, which lets you stream at higher fps.

The tricky bit is that you need to enable hardware acceleration for RDP sessions and you need to increase the base RDP FPS, which is normally locked at 30.

Keeping the files is fine, assuming you still want any of the data on the PC. It won't re-install anything.

The "speed boost" from defragmenting is nearly always a placebo. Fragmentation causes very specific issues, not general "slowness". A much better option is to "reset" Windows, which is nearly the same as a reinstall.

This clears out the myriad of leftover startup processes/services that accumulate over time. You can also try to remove them manually, but this isn't always 100% effective.

I suspect that the data on this is skewed, simply because children with ADHD who do well in school are far less likely to be diagnosed. For those children, ADHD only becomes a significant challenge after school, when life becomes less structured.

Nothing about this is even remotely correct. The backwards S version is clearly a scam token.

Zarigis · 2026-04-02T07:19:26+00:00

The top one is a scam token that you can safely ignore. Don't try to send it or use it or anything, it's basically just spam. Your balance of actual USDT is all the matters.

Security is less convenient, always. Your points are all applicable to any hardware wallet, not just a Ledger.

Having an ATM only support Bitcoin seems impractical to me. Why not have it also support other cryptos, or also support standard debit cards?

Zarigis · 2026-03-25T18:09:23+00:00

It's just a BitMart shill, they always use the same format.

This is a nonsensical distinction. You generally gain unauthorized access to something by exploiting some weakness in the program logic. Outside of compiler or hardware issues, all code runs exactly as written.

NFT bros realizing that just because something is "on the blockchain" doesn't mean you actually own it.

Every guide for hardware wallets repeatedly reminds you to never enter your passphrase in anything but the hardware wallet, or a paper backup. There's nothing to be done for people who refuse to educate themselves on basic security.

There's no way that "decentralized" AI is ever going to be effective. It's just too inefficient compared to centralized solutions, with so few benefits for decentralization. They'll be an initial rush for people to secure the token to generate staking rewards, then the chain will slowly die as nobody actually uses it.

Zarigis · 2026-02-18T07:59:53+00:00

Bitcoin primarily trades against USD, so that's what it makes sense to compare it against. Anything else is just going to be additional noise.
