Speaking of WebAccessibilityFails, the article overflows to the left without a scrollbar when viewed on a phone narrower than an iPhone, making the first word of every line unreadable (and there are a lot of lines on a phone narrower than a

There was once a privilege escalation vulnerability in Linux kernel that only happened when compiled with optimizations. In kernel space, address 0 is just regular memory that can be read from and written to if there's a page mapped to

100% agreed on the sloppiness. But overflow checking is not sloppiness. It's the opposite of sloppiness. Unchecked math is sloppiness, allowing overflows to happen silently and uncontrollably is sloppiness. It just so happens this kind

In practice, GCC -O2 will happily erase entire swathes of code and turn perfectly logical source into nonsense assembly whenever it gets as much as a sniff of UB anywhere in the code path. Nobody would be talking about UB if GCC wasn't

Are they, though? Does the end customer get more post-transaction protections when not using 3D Secure? That doesn't sound right. I'd think the merchant is on the hook exactly as much either way.

by Xirdus 5mo ago
The problem with 3D Secure is that the merchant can unilaterally decide not to use it, which defeats the whole purpose of 3D Secure.

I interpreted these words: > If you want to be standards correct, yes you have to know the standard well. to mean that being standards-correct is optional. It's not. Every C programmer needs to know every possible UB by heart and ne

If you don't follow the standard, gcc -O2 can introduce bugs to your code that you never even wrote. Skipping null checks, executing both branches of a conditional, and so on.

But did they build this different harness? And are they sure other models can't cope with it?

Disagree with the last one. Back when unions were more common in my country, union officials were the gatekeepers of career progress or even entering the profession, and they were taking bribes. I've never seen an HR department half as

Of course it's because of imperial units. TIL, thanks. But on a sidenote, I question the utility of knowing x11 and x12 when working with time. x15 could be useful, unfortunate they don't teach that (but I think most people with h

Up to 12? Is that a British/Anglosphere/Victorian thing? In Poland they teach up to 10, which is suffinient for arbitrarily large numbers because they also teach long division and how to combine it with times table. Technically up

Well, one could argue that the lesson from CVE-2017-0780[1] should've been "don't automatically decode rich messages from untrusted sources". [1]: https://www.trendmicro.com/en_us/research/17&#x

Everything needs branding. "United States of America" and "USA" is branding. Good branding makes people's lives easier and (on average) a tiny bit happier. That has some impact on quality of life. Spending a few tax

Once you stop thinking of domain as an addressing tool and start thinking of them as branding, the complaints will make sense. "Dot k12 dot oh dot us" is a terrible brand name.

In a way, yes, that makes it more okay. You can't have a conflict of interest if you have no interest. Cloudflare has clear interest in hosting the malicious actors and it's in clear conflict with providing services to their other

If company A is Amazon, company B is Ubisoft, and company C is Oracle, then I think it's very likely there isn't any pattern or "loop" here and it's legitimately just 3 different companies in 3 different situations

ICANN doesn't get any kickbacks from Canonical needing to protect itself as far as I can tell. Cloudflare literally sells the protection.

So, did your Claude switch from "You're absolutely right!" to "You're absolutely right." or was it deeper than that?

It makes the exploit code more readable. We all love to laugh at C folks but for real, even Linux kernel maintainers care about readability.
