dx034··on Uncovering a 24-year-old bug in the Linux Kernel (2021)
When you need working software at the end of the sprint, there's often no time to carefully control for all edge cases.
dx034··on Uncovering a 24-year-old bug in the Linux Kernel (2021)
I've frequently run into problems with Postgres streaming replication that looks exactly like the issues encountered here. I was never able to find the source of the issue, so I'm very curious if this fix will also fix the issues I encountered.
dx034··on Intel plans thousands of job cuts in face of PC slowdown
It's important that Wall Street is not just some people but the owners of the company. So it's a signal to the owners that their money will be better spent.

Just saying Wall Street sounds very dismissive of the obligations that management has to the owners.

dx034··on Google Cloud announces Dual Run to ease mainframe migration to cloud
> Why is this important? Well for starters, 44 of the top 50 banks and 23 of the top 25 largest U.S. retailers still use mainframes, according to Google.

I'd rather be interested which 6 top US banks already manage to run without mainframes. And if they can run their systems cheaper/more flexibly or are stuck with SAP/Oracle contracts that are as expensive and hard to change.

dx034··on Google is shutting down Stadia
How can they lose money at the prices they charge? They already had all the expertise to run data centers and build infrastructure. I get that there's development effort, but how can you bleed billions annually over years? Or do they discount that heavily for large customers?
dx034··on Uber investigating breach of its computer systems
And as other people have already written, that's the main issue. Not that someone got compromised, but that passwords for admin accounts to all those services were stored on a network share.
dx034··on Uber investigating breach of its computer systems
Maybe just clicking around until they found something. That's what many employees do on a daily basis looking for files on network drives, so nothing that would be noticed easily.

Recently my phone broke and it took a day to get a new one. I was so glad to have my 2fa codes somewhere else as well. I'd never want to rely solely on one device for access to everything.

Apples plan is that I need to own several Apple devices for that, this is a non-starter for me.

dx034··on I Use a Chromebook
An old Thinkpad works well for me for those use cases. I replaced a Chromebook with an old x1 carbon and it works really well. Easy to upgrade and works equally well with Windows and Linux.
dx034··on What Happened to Amazon Prime 2-Day Shipping?
It's the same in Europe. With prime you used to get most items the day after order, rarely two days after ordering. Now it's at least 2 days for most items, many even only arrive 3-4 days after ordering. And that's even if you're close to a major distribution center.
dx034··on Ask HN: What Linux setup/hardening guide do you use?
Is older hardware that is performant not secure? I never had the feeling that securing a linux server slowed it down.
dx034··on Amazon, Verizon found using IPv4 240/4 addresses
I never got why they had to make it that large. I doubt we'll ever want to have that many devices with their unique ip. So why not have a simpler system that makes switching easier? Even one octlet more in ipv4 would've sufficed for a very long time, two would've probably been enough forever.
dx034··on Amazon, Verizon found using IPv4 240/4 addresses
Honestly, if IPV6 had been v4 but with 2 extra octlets, I believe we would be at close to 100% adoption. And also wouldn't run out of ips anytime soon.
dx034··on Amazon, Verizon found using IPv4 240/4 addresses
Hetzner is actually good there. They now charge you separately for ipv4 but give ipv6 for free. And when they changed it, they reduced server prices by the ipv4 price. So you could actually save money switching. It tends to be 5% or less, but seeing it a separate line item might make people think if they really need ipv4.
dx034··on Amazon, Verizon found using IPv4 240/4 addresses
The question is why China is so low. They must have close to a billion mobile devices only at any time. Other countries aggressively use ipv6 for those, I'm surprised China doesn't. Or Google just doesn't see the real traffic in China?
dx034··on Amazon, Verizon found using IPv4 240/4 addresses
That's just the path from the user to the gateway (usually a CDN, rarely the server where a website is hosted). Behind that, pretty much all is IPV4. And there's not reason to change, very few companies exhaust the private address range. But as long as everything behind the first gateway remains ipv4, sysadmins will mostly work with ipv4 and ipv6 will never make a real breakthrough.

I believe even in 10 or 20 years, we'll see ipv6 only on public traffic, anything else (which is much more both in traffic and ips) will remain on ipv4.

dx034··on Amazon, Verizon found using IPv4 240/4 addresses
Absolutely. I'll say it again and again, I like NATs, especially for home setups. They help hiding devices from the public that never need to be accessible outside of a LAN. And you can never trust home router firewalls to be configured correctly. If all devices had their unique IP address, we'd see much larger botnets out there.
dx034··on Denmark bans Gmail and Co from schools due to privacy concerns
No, you only need Facebook and TikTok in very few office jobs (and there probably other interfaces than users typically use). Excel is present in pretty much all office jobs. Maybe not all programmer jobs, but apart from some backend coders I haven't seen many people who never had to work with Word or Excel.
dx034··on The Dangers of Microsoft Pluton
And Apple had to revert it and got punished for it. What more do you want?
dx034··on Denmark bans Gmail and Co from schools due to privacy concerns
Maybe what you need to know, but not how to use the programs. I was very anti Microsoft in my school days but had to learn Excel and Word in school. It helped me so much in my first job.
dx034··on Denmark bans Gmail and Co from schools due to privacy concerns
Fastmail is good but more if you don't use it in bigger team (my opinion). Why don't you want to use exchange? Shouldn't be too bad as long as it's configured by MSFT?
dx034··on Denmark bans Gmail and Co from schools due to privacy concerns
I'd have to disagree here. Teaching kids how to use Word and Excel will help them for the majority of office jobs out there.
dx034··on The Dangers of Microsoft Pluton
Secure chips like this are already in all devices but PCs. And in none of these areas has any of that happened. Quite the opposite, Apple got a fine when they slowed down older devices to save battery (at least what they said).

So the government will clearly help out here. And none of these companies has an incentives to stop sales to smaller companies, they make a lot of money with those.

dx034··on The Dangers of Microsoft Pluton
And that's why Microsoft needs to include such a chip. If we move to a world where security is enforced more and more by hardware, you'll need a device that can participate.

> From the USA, we get news of banned book in some states. When I read that, my head goes back to my european history, and I reach the Godwin point very quickly.

Books are not banned, just not used in the classroom anymore. While the reasons for it may be wrong, it's something that happens constantly all over the world. No one prevents children or adults to read those books at home. Banning books could mean that owning them is illegal and that just hasn't happened.

dx034··on No evidence for nudging after adjusting for publication bias
Not very scientific, but isn't it just laziness? Most people (including me) are too lazy to think about all the choices they could make, so they just stay with the default choice most of the time. Not because they actually prefer it, mainly because they never even read it.
dx034··on More invested in nuclear fusion in last 12 months than past decade
Any green gas could be that storage. With solar power around $.01/kwh in some sunny places, converting that energy into storable gas/liquids can be profitable even at low efficiency rates. And we already have an existing network to transport, store and burn gases. Converting those from natural gas to other gases is likely easier than rebuilding everything.

From all that I read, Ammonia is a prime candidate. Especially because there's an existing large market for it, so producers don't have to bet on a new market to ramp up production. But there's no real reason why some power plants, ships and maybe even trucks couldn't be driven by Ammonia in the future.

dx034··on Ask HN: Why are there so few artificial sunlight or artificial window products?
I don't think there's any malice. They're far superior when it comes to energy consumption. And they generally work well. They're just part of a general trend that it's hard to find high-quality products anymore. Unless you have industry expertise, it's extremely hard to determine which appliances are usable. Traditional DYI stores sometimes provide that expertise, buying online it's nearly impossible to search for quality.
dx034··on Datadog dashboard for the Texas power grid
I know it's not issue free. But Europeans tend to pay a premium to avoid its shortcomings rather than have blackouts. And I prefer that over having cheaper electricity but with a threat of blackouts.
dx034··on Ask HN: Why are there so few artificial sunlight or artificial window products?
I've already replaced dimmers to work with LEDs. But changing all fixtures would be way too expensive, it'd then be cheaper to just stick with Halogen. And I don't need any "smart" features, an LED that can be dimmed via an external dimmer would be enough. But they're harder to find than all these "smart" devices that might stop working after a few years and can send data to who-knows-who.
