While playing around with modern NetBSD on a system with just 10 megabytes of memory, I ended up getting and adding an m68881 just so that I could remove the floating point emulation code from the kernel to save a few kilobytes. OTOH, who d

I think the 80386's final design benefitted tremendously from the Motorola 68000, then the m68020. Had Motorola not released a proper 32 bit CPU without compromises, it could be argued that Intel would've had yet another stop-gap

So Alpha, m68k and even VAX have outlived Itanic. Poetic.

I'd love to learn more. Is a translation available somewhere? Note: Google translate does decently well here.

Indeed. "We broke the RSA-2048 key" is the equivalent of "I have no idea what I'm talking about, so I'll just say something slightly less dumb than what you'd see on NCIS".

The difference is that nobody complains and most people agree when you talk smack about Amazon, Google and Microsoft. The general consensus is that they're big, dumb and knowingly evil, and most of the time their actions can be explain

Should we simply ignore the tremendous amount of phishing hosted using r2.dev? Or is this also part of "an economic opportunity"? Cloudflare may well be on their way to becoming a monopoly, but they certainly show they don't

Cloudflare's rather shitty abuse reporting web form is broken now, too, with this error returned after a minute after submission: An unknown error has occurred and has been logged. We apologize for the inconvenience and we will f

Early MacBook Airs had spinning rust hard drives, FYI, similar to what were in iPods. That still doesn't mean that Apple was trying to make the Air and couldn't because of the PowerPC. They could've easily made one with a low

A few things: You're a bit apostrophe happy. Sure, as a matter of style and preference you can use apostrophes to pluralize short words / acronyms, but "it's" is a contraction for "it is". An AMD Ryzen 270

The problem with IPMI / iLO / iDRAC is that they're not secure. You can't safely put them on the Internet, so you need to pay your colocation provider for out of band connectivity and a separate drop. To save money, I ha

Nobody has to upgrade. m68030 Macs still worked after the PowerPC transition. I used my Mac mini G4 for years after the Intel transition, and still use both an m68030 Mac and that G4 mini with NetBSD now. Currently I'm running Sonoma

I appreciate articles like these because they're useful for people who don't know the background and details and aren't interested in a deep dive, but it'd be nice if the author spent a little more energy on details and

You mean Yahoo isn't the rotting carcass of the company it once was? I see nothing but decay: their abuse addresses don't work, nor do any of the addresses they have in WHOIS, either for their domains or their networks, that haven

Core Rope Memory, which contained the programs that landed man on the Moon in the 1960s, is insanely complicated. But that won't stop Mike from making a custom reader for it, so he can recover Apollo Guidance Computer programs lost to

I'm glad projects like this exist, but I'm too lazy and more than happy to have a Pi provide a serial console and a hardware reset via GPIO over IPv6 for colocated hardware. It's much simpler ;)

Nobody says they stop working. They do end up slowing down much more than other CPUs when mitigations are applied.

Then Intel should correct their own documentation. If not in fact, they're intentionally limiting their products in spirit. https://ark.intel.com/content/www/us/en/ark/products/231803/

Intel has been a one-trick pony for ages. Intel's advantages come at the cost of power, the need for active cooling, and the fact that code for ages has been optimized for x86. What people don't often consider is how poorly Intel&

Yeah. Reminds me of Microsoft people saying the iPhone isn't going anywhere in 2007. I'm still running a 2010 MacBook Pro because I wasn't ever going to upgrade when the only options were still Intel. ARM just makes the most

This is an excellent example of how large corporations can't plan products normally any longer. You could take a college class in embedded systems design and you could ask all the students to come up with examples of edge cases where a

If you want to go down a deep, dark, sad rabbit hole, look in to the digital audio part of the "audiophile" world. For me it began when I looked at a friend's catalogue that had a $2,500 (25 years ago) CD player that claimed

I think the point was that anti-lock brakes remove options and make things less safe in certain (not very uncommon) instances. With anti-lock brakes, you're protected if you've never learned anything and you just try to put the br

You asked good questions in that article. It's unfortunate, and I can't help but wonder if we've lost something essential because of how uncommon it is for people to be proud of their abilities, proud of their work, proud of

As a systems administrator who has been doing this for a while, I can attest to this becoming more and more of a problem. I've worked with CUDA programmers who weren't aware of what "architecture" means in the context of

Sure, but sometimes they're not. Those sometimes can be very, very critical. Think of the Red Hat (and others) local privilege escalation, for example: Red Hat released a CVE with vague language and with no clear steps to take. If you
