FastEatSlow··on Tell HN: Godaddy canceled my domain, gave me 2h to respond, then charged €150
I haven't had issues with let's encrypt with them in the last 2 years, though I do recall seeing free SSL promotions and never a certificate.
FastEatSlow··on Ask HN: What are you working on and why is it cool?
An alternative Microsoft Teams client. It's cool because it doesn't warm your computer as the official client does. (https://www.opercom.co.uk/) the website needs a complete revamping and the UI is being changed to be more modern.
FastEatSlow··on Ask HN: Leaving Germany – where to find quality of life as experienced engineer?
I second this, primarily because I was chuckling the entire time there. Czech is quite funny to Polish speakers [1].

FastEatSlow··on Open rights group sound ‘Red Alert’ as UK announces bonfire of data rights
This certainly looks scary, but it's a bit difficult to understand right now even with their explanations, hopefully this bill will have more attention.
FastEatSlow··on GrapheneOS: The private and secure mobile OS
Avoid buying a GrapheneOS phone being advertised specifically for privacy with encrypted chat. They are specifically for selling to criminals, be it from a government or an enterprising young adult.

Many people have tried to pay me to make them a custom ROM based on GrapheneOS but with their name and reskinning notepads and encrypted chat apps. They'll claim it's for privacy-focused businesses of course.

FastEatSlow··on Your compliance obligations under the UK’s Online Safety Bill
IP over Avian Carriers https://datatracker.ietf.org/doc/html/rfc2549
FastEatSlow··on Optimized for no one, but pretty much OK with… (2003)
I'm surprised at how many browsers there once was. Were they all custom or did many share the same base, like the current situation with Chromium and Firefox?
FastEatSlow··on Ask HN: Do you clean out your downloads folder after each download?
My downloads folder is /tmp. If it's needed, I'll move the file to an appropriate location in Documents.
FastEatSlow··on The Demo → Demo Loop: The secret to making successful creative products
Demo-first looks good, it certainly tracks with my experience that building something needs to be shown off at every step to catch issues and get people excited.

I'm not sure how this includes fixing bugs and general maintenance though, short of showing one side of a video with the software crashing and the other not.

FastEatSlow··on Drone swarms that harassed navy ships demystified in new docs
Many hobbyist drones are flying Linux computers [1], so it's not a stretch that an autonomous drone could be constructed.

FastEatSlow··on Restarting my career after motherhood
Old people need a pension, which is paid by the workers through taxes.
FastEatSlow··on Restarting my career after motherhood
The process of shrinking to fewer humans is painful however: less people working, more people old and unable to work.
FastEatSlow··on Show HN: I spent my vacation writing a modern JVM assembler
Brilliant, much better than having to use heavy and clunky tools like recaf or jbytemod, or one-off java projects with ow2 ASM to create custom classes.
FastEatSlow··on Make Your Own Chips for Free
If a design includes many analog components then it is effectively required to fab a prototype. Analog simulation is very imperfect, and the analog equivalent of an FPGA, Field-Programmable Analog Array (FPAA), are very limited in resources. [1]

FastEatSlow··on Ask HN: Recommendation for the mom of a near-college-aged “tech geared” student?
The courses look brilliant, definitely a strong advantage to gain a reference from a Cambridge postdoc. I'd take part if the £2.5k for online or £5k for residential was much lower, but it's understandable why the fees are so high.
FastEatSlow··on Lets talk about blockchains
An interesting point from the LockPickingLawyer that I'd like to point out is that while many, many locks are easy to break if you're interested, it's still effort. Your average locker or bike thief isn't picking locks, they're just taking whatever's easiest.
FastEatSlow··on Countering threats from North Korea
Web assembly is extra code and complexity in a web browser compared to one without, so there are more potential vulnerabilities
FastEatSlow··on National Forensic Academy teaches to dowse for the dead
My engineering teacher showed us last year how to use dowsing rods, it was very odd watching the rods cross over a puddle. The article focuses heavily on the historical "witching" use case for these, which is of course nonsense, but it makes sense that dowsing rods work for decomposing bodies, considering that there's not that much difference between a dead body and a puddle of water.

We don't know how or why dowsing rods work over bodies of water, but they're good enough for our water companies to use. If it was completely luck, then they (hopefully) wouldn't do it.

FastEatSlow··on Medical student surgically implants Bluetooth into own ear to cheat in final
The surgery was done by an ENT (ear, nose, throat) surgeon. I'm not sure if it was within the ear or not, as the device was "skin coloured", though that may be because of how thin the ear's skin is.
FastEatSlow··on Show HN: All desktop software calculators are wrong, so I had to build my own
Chrome's developer tools has a device toolbar to help you test usability on mobile devices.
FastEatSlow··on Malware now using Nvidia's stolen code signing certificates
Based on the certificate authorities linked to by Microsoft [1], around $400 to $700 a year, depending on the type of certificate. Extended validation certificates grant the software a better reputation with antivirus products, but I don't know if there is actual validation involved, or if it's just buying a rank.

FastEatSlow··on Duck DNS – free dynamic DNS hosted on AWS
DuckDNS is sadly often abused for malware and phishing.
FastEatSlow··on Ask HN: What do I need to learn to be useful as a hacker to defend my country?
The current cyber reservist page is:

FastEatSlow··on Tell HN: GitHub leaked names of private repos with pages
On the off chance that's not sarcastic, I doubt we have.
FastEatSlow··on Tell HN: GitHub leaked names of private repos with pages
> You have to code as if someone you don't want will be reading it.

This reminded me of "Always code as if the person who ends up maintaining your code is a violent psychopath who knows where you live."

FastEatSlow··on Ask HN: Recent computer hacking convictions and employability?
Yeah I've noticed it as well. I suppose it's because the GCHQ can't necessarily pay enough for very talented individuals who are required for certain work, whereas defence companies are somewhat poured with funds. I've heard that a popular path is to start in the government, then to the private sector to earn bank, and then back to public.
FastEatSlow··on Ask HN: Recent computer hacking convictions and employability?
Very high, zerodium [1] offers from $10k to $1mil depending on the exploit.

FastEatSlow··on Discord is a black hole for information
I'd argue that it's not too significant of an issue, as generally most clients do a good job of presenting themselves with completely normal behaviour to the discord api. Most people are banned because of API limits, such as attempting to spam without keeping in mind the limits, (Random delays with around 1 msg/s last I tried), or there's a bug in the client, such as ripcord once causing a login loop for me. If you keep it sensible, it's fine. Most people using these custom clients know the dangers and keep information on how to get back into everything, so there's not too much of a black hole effect.
FastEatSlow··on Life, school, and the 80:20 rule (2019)
I agree that it's very easy to tell between the students of a great teacher and a bad teacher. I've found that the best teachers are ones that came from industry, they did their work, and then went into teaching. That's why my school's engineering department is great, as is one of the physics teachers who sadly only teaches me once every 2 weeks.
FastEatSlow··on Web hacking techniques of 2021
Yes, actual threat actors use these techniques even after publication. There is a lot of outdated/misconfigured systems in the wild. A fairly recent example is the defacing of multiple Ukrainian government websites[1], through exploiting a vulnerability fixed and publicised in august 2021. There's also around 10,000 (can't remember where that statistic is from) Huawei routers on the internet vulnerable to an issue from 2015, which are constantly being infected with botnet worms.
