Because it's there.

Something breaking after 49.7 days is a classic. Someone counted milliseconds since start with a 32 bit unsigned int and some code assumed it couldn't wrap.

There are self-hosted options too. I can't vouch for any of them but many look competent.

Win32 and Wine being a lightweight alternative to HTML and Electrum is a fun idea.

This is why I used ReadItLater and now Instapaper. It's integrated in my ebook reader too.

Most users have JS enabled nowadays. Much of the web doesn't work without it. It was just an example.

No it does not. I've had this happen in legacy systems myself. The checksums of TCP/IP are weak and will let random errors through to L7 if there are enough of them. It's not even CRC and you must bring your own verification if it's critical for your application that the data is correct. TLS does that and more, protecting not only against random corruption but also active attackers. The checks you get for free are to be seen only as an optimization, letting most but not all errors be discarded quick and easy. Just use TLS.

Men in the middle including predatory ISPs can not only spy but also enrich. Injecting JavaScript and embedding ads is the best case scenario. You don't want that.

In addition even without bad actors TLS will prevent random corruption due to flaky infrastructure from breaking the page and even caching those broken assets, preventing a reload from fixing it. TCP/IP alone doesn't sufficiently prevent this.

New comment by swinglock in "IPv6 just turned 30 and still hasn't taken over the world"

swinglock — Fri, 02 Jan 2026 19:18:18 +0000

IPv6 and CGNAT growth has finally started to suppress IPv4 prices. There was a huge pump when hyperscalers decided they needed more. But IPv6 keeps growing and is the majority of traffic in many networks. If you own significantly more IPv4 addresses today than you need, I would dump them on the market yesterday. Spend some of the profits to move to IPv6 if still needed.

Well but then attackers just compile a kernel with a rootkit that hides the hack and itself from the APIs of the BPF program, so it has to deal with that too or it's trivially bypassed.

Anticheat and antivirus are two similar but different games. It's very complicated.

New comment by swinglock in "No strcpy either"

swinglock — Tue, 30 Dec 2025 16:02:53 +0000

assert() is always only compiled if NDEBUG is not defined. I hope DEBUGASSERT is just that too because it really sounds like it, even more so than assert does.

But regardless of whether the assert is compiled or not, its presence strongly signals that "in a C program strcpy should only be used when we have full control of both" is true for this new function as well.

I'm surprised curlx_strcopy doesn't return success. Sure you could check if dest[0] != '/0' if you care to, but that's not only clumsy to write but also error prone, and so checking for success is not encouraged.

The latest DLSS and FSR are good actually. Maybe XeSS too.

This used to be a feature to protect spinning hard drives. Why this would exist today and why it would throttle anything is bizarre.

You should block the whole /64, at least. It's often a single host. It's often but not always a single host, that's standardized.

> There were too many apps; all they wanted was the phone app, but it doesn’t default to the keypad, which was too much for them to find.

Then why buy an iPhone? There are phones designed for seniors that do just that. You don't need to pay 10-30x more for functionality you don't need and can't understand. Buy a Doro if you just want to call.

Though it's rich coming from a kernel lacking a better filesystem of its own.
