kdklol | 11 days ago | on: 10% of Firefox crashes are caused by bitflips

I'm glad to see somebody is getting some data on this, I feel bad memory is one of the most underrated issues in computing generally. I'd like to see a more detailed writeup on this, like a short whitepaper.

I was recently searching for NiMH charging ICs, turns out they basically don't exist. Most devices which charge their NiMH batteries implement low CC charging, which is slow. It's a shame, because NiMH batteries do have their advantages (safety, ease of finding replacements, etc.) and can be recharged fairly quickly if the charger is smart enough.

>You can't just assume UTF-8

But I will, because in this day and age, I should be perfectly able to do so. Non-use of UTF-8 should be simply considered a bug and not treating text as UTF-8 should frankly be a you problem. At least for anything reasonably modern, by which I mean made in the last 15 years at least.

kdklol | 2 years ago | on: Czech government to stop offering services over IPv4 on 6.6.2032

It's not wrong though. Besides North America, there are major carriers in India, France who use IPv6-only networks (with 464XLAT), and I know several South American and Asian countries have them as well. In fact, India is a world leader in IPv6 adoption. Nowadays it's a very common for mobile networks to be IPv6-only because these providers haven't been able to secure large Ipv4 subnets in the early days. Ironically, they have the most devices. However, this is also the reason why phones work much better with XLAT than Windows or Linux.

You are correct, Czechia is a parliamentary democracy. Usually, the government is formed by the parties that together have a legislative majority in the lesser chamber.

I should clarify that this is not a law, rather a "government decision" (a la "executive order") on how to act on it's law. Forgive me, I'm not well versed in legal English, and the systems are quite different.

kdklol | 2 years ago | on: Czech government to stop offering services over IPv4 on 6.6.2032

Allow me to append a short summary in English:

- The Czech government adopted a new directive titled "The restart of DNSSEC and IPv6 enrollment in the government"

- Until yesterday, no administration on the European continent has made such a decisive step as setting a end-of-support date for IPv4

- Selected date is highly symbolic, the 6th of June, 2032, the 20th anniversary of the World IPv6 day

- This decision has already sparked discussion on the RIPE NCC forums

- "It's a signal to all internet players to take IPv6 seriously"

- Nevertheless, the EU itself has already taken even greater leap towards IPv6 adoption

Yes, I meant upload, sorry. Downloading from a page is trivial. I was more concerned ith the case of grandma sending a picture or similar.

I don't disagree, but few non-techies will be able to download an image off of an FTP server or mount an NFS share. Thats where such a service adds value.

kdklol | 2 years ago | on: Ask HN: Got a /22, cool things to do with it?

Good question! It's spiking up on weekends, the reason for that is that corporate networks are not as incentivized as large public ISPs to adopt IPv6. They have a lot more customers and are more directly affected by IPv4 exhaustion, especially the mobile providers.

kdklol | 2 years ago | on: Ask HN: Got a /22, cool things to do with it?

There's a management system that assigns IPs automatically, written in-house in the late 2000s, but yes, anything there can be manually overridden. He was probably diagnosing something earlier and forgot to clean up. Meanwhile, new students moved in I guess.

Missing IPv4 addresses are not reported as some systems are left IPv6-only intentionally. It's a dorm network, but it's sort-of a research project at the same time. It is also run by students themselves (there's a "student's union") and the school does not pay or maintain the dorm's infrastructure.

I know alerting is done for some things, but not for the individual student's machine. This is different for every dorm, but in this case, a wired symmetrical gigabit connection is provided to every member student, public IPv4 and IPv6 included. The only restriction is to not download torrents, besides that, pretty much anything can be arranged, including opening port 25, routing additional IPv6 prefixes, hosting...

It's a very free environment is what I'm getting at.

No, in general, the smallest block of IPv6 addresses you can "own" is /24. You have to pay yearly fees to your RIR (Regional Internet Registry) as an ANS (Autonomous system). Think of it as owning land and paying a land tax.

kdklol | 2 years ago | on: Ask HN: Got a /22, cool things to do with it?

Realistically, you should sell it while it's valuable. Take a look at IPv6 adoption. I know, I know, "IPv6 will never be here blah blah blah", so the naysayers say, but look at what Google is getting now, for instance:

https://www.google.com/intl/en/ipv6/statistics.html

We're counting down the years before IPv6 will become the major protocol, after which, IPv4 addresses will slowly start to loose value.

"But it's only FAANG, noone else has IPv6!" Just not the case anymore. But even if, most people don't care about anything else anyway. I have a friend who helps to operate a university dorm network. Allegedly, he once removed an IPv4 address by mistake from one student's computer. He only heard about it half a year later, when the student casually mentioned that only Google, Facebook and other big sites seem to work. Apparently, if Google, Facebook, and the School's website works, it's acceptable to most (which is sad for different reasons, but that's not my point).

Anyway, that's still at least a few years away though, you can have some fun with it for now :)

kdklol | 2 years ago | on: SSH3: SSHv2 using HTTP/3 and QUIC

With /passkeys/, actually! It's more generic than just hardware keys. I don't know of any good implementation yet, but there were a few projects on github mentioned in some passkey-related discussions here. I do not use anything like iCloud or Windows Hello and I don't know what these services actually use, but if they implement these open standards, it's only a matter of adding some glue code. I'd say it's likely that Putty will implement this over on Windows eventually. That is my speculation, as I said, I don't actually use any of this.
