That's not my experience at all. I was approved fairly fast - around an hour from submitting the form and getting a response.

However, even being in the cybersecurity programme, Fable refuses to answer prompts that it determines could be even tangentially related to cybersecurity. In fact, for a while, I was unable to use Fable with any prompt, as it recalled from memory that I was a cybersecurity professional, which triggered the refusal even for simple prompts like asking for a chili recipe.

Both projects have the same author.

I got the same vibe from

Thanks? This sounds like it's the LLM's response to the prompter, not something you should display on the page itself...

I think this is a slightly different problem. The absence of an optional field, if that's a legal state, is meaningful every time you use the type, so you encode it on the field: `phone: ValidPhoneNumber | null`. When it's not null you're still guaranteed a valid phone number. When it is null, that's a legal state you have to handle and which is domain logic, not validation you forgot to do.

The combinatorial explosion you're picturing only shows up if you make a separate type per combination of present fields, but you don't need to. An independent optional field stays one `T | null`. You only reach for distinct types when fields are correlated and present together because they represent a state, and then it's a discriminated union on a status field, which is N states, not 2^N.

This campaign is still ongoing. I just got an email that one of my old packages (which hasn't worked for years and was orphaned for a while) was adopted and immediately a malicious commit was pushed. They seem to be using bun instead of npm now, so any npm-based workaround likely isn't effective.

That would've been a cool PoC to work on as well, but seems a fair bit more complicated than the BadUSB-style attack I ended up doing. Would've had to do a lot more RE to figure out how to interact with the whole microphone subsystem, I think.

> A probe packet contains the MAC address as well as the list of all the past Wi-fi networks that your device has tried to join before, which can reveal a lot about you!

Generally, most modern devices send broadcast/wildcard probes precisely to avoid leaking the PNL. From what I know, directed probes are only sent for hidden APs.

From personal experience, there have been a few papercuts (mostly trying to figure out why runners aren't picking up jobs), but it isn't too hard to debug and the CI format is simple. When it works, it works well enough. It uses a similar workflow as GitHub actions. Some, but not all, actions are even interchangeable or at least portable from GitHub without much fuss.

I'm not from the US, so I hope you excuse my ignorance, but who exactly voted for mass surveillance or AI cameras?

I wish my city only had a single case like that. Unfortunately, in Tallinn, it is extremely common that a bike path is suddenly routed onto the curb, and that's when you're lucky. For some paths, the path just... ends, and you suddenly find yourself right in the middle of car traffic. Unfortunately, the city leadership is anti-bike and pro-car, and it shows in the infrastructure.

Paths where pedestrians and bikers (and other light transportation vehicles) are mixed are overwhelmingly common.

According to the linked homepage, the memory usage seems decent (few hundred megs for most use cases when working with a 3.3G logfile). There's a screenshot with various tasks and what the peak memory usage is.

At some point you need to keep quite a large context in memory to have both decent performance and useful features (that aren't unbearably slow to use). lnav seems to land at a reasonable middle ground.

Good question! I wasn't too concerned about this, because the only way you could even interact with the OS where the server was running was via HTTP requests, which are fairly limited in nature. The OS or kernel itself wasn't directly exposed per se.
