In fact, the broken bar barely even exists anymore. In the days of DOS, the character used for the pipe symbol (on the DOS command line) or for logical OR (in C/C++, for example) used ASCII code 7Ch (124 decimal), which was rendered as a broken vertical bar by the fonts used at least by the IBM MDA, CGA, EGA, and VGA cards. But nowadays that is no longer the case. The same ASCII codepoint is rendered as a solid vertical bar in Windows 10 or Linux, and also shown as a solid vertical bar on contemporary keyboards. What happened?

Who doesn’t love some great character and ASCII archeology?

Microsoft laid off its entire ethics and society team within the artificial intelligence organization as part of recent layoffs that affected 10,000 employees across the company, Platformer has learned. 

The move leaves Microsoft without a dedicated team to ensure its AI principles are closely tied to product design at a time when the company is leading the charge to make AI tools available to the mainstream, current and former employees said.

Oh so that’s totally not worrying at all or anything.

Coming up with a title that explains the full story here was difficult, so I’m going to try to explain quickly.

Yesterday, Docker sent an email to all Docker Hub users explaining that anyone who has created an “organisation” will have their account deleted including all images, if they do not upgrade to a paid team plan. The email contained a link to a tersely written PDF (since, silently edited) which was missing many important details which caused significant anxiety and additional work for open source maintainers.

What a shitshow. We really have to start worrying about the future of Github, too, since I find it highly unlikely Microsoft isn’t planning similar moves in the future. If you’re hosting code at Github, I’d suggest looking at alternatives sooner rather than later, so you don’t end up like the people affected by something like this.

Apple and its manufacturing partner Foxconn were among the companies behind a landmark liberalization of labor laws in the Indian state of Karnataka last month, according to three people familiar with the matter.

Their successful lobbying for new legislation means two-shift production can take place in India, akin to the two companies’ practices in China, their primary manufacturing base. The law gives the southern state one of the most flexible working regimes in India as the country aims to become an alternative manufacturing base to China.

“We do the right thing, even when it’s not easy.”

If you’ve been reading my blog for a while, you might remember back in 2012 when I changed the startup sound on my Power Mac G3 (Blue and White). That was a fun introduction to the Forth programming language. I had to reverse-engineer just enough of Apple’s firmware update script to understand what was going on.

Recently, Aidan Halpin, a reader of this site, asked me if I could do the same kind of startup sound customization on his iMac. This particular iMac is officially known as the “iMac (Slot Loading)” and has a model identifier of PowerMac2,1. As you can guess from the name, it has a slot-loading CD-ROM drive unlike the original iMac that had a laptop-style tray-loading drive. By the way, Aidan’s iMac is special because it has a PowerPC G4 processor soldered onto the logic board instead of the original G3.

He sent me Apple’s last firmware update for this model: iMac Firmware Update 4.1.9. I went to work looking at the update contents to see if I could figure out how to modify the chime the same way I did with my Power Mac G3. I thought it would be fun to take everyone along for a ride and show exactly what was involved in changing the sound. And of course, this post wouldn’t be complete without also sharing the code for the utility I created to inject the new chime into the firmware update file.

This is an insane amount of work for something that doesn’t really matter in the end. I love it.

Here’s an interesting bit of news out of Mobile World Congress: Qualcomm says the Snapdragon 8 Gen 2 has been certified as the “world’s first commercially deployable iSIM (Integrated SIM)”. What the heck is an iSIM? Didn’t we just go through a SIM card transition with eSIM? We did, but iSIM is better than eSIM. We’ll explain, but the short answer is that iSIM is the next step in the continual march to reduce the size of SIM cards.

[…]

eSIMs are still a chip taking up space on your motherboard, and that’s not ideal if you want to squeeze every square millimeter of space out of a phone. The next shrinking step is iSIM—an Integrated Subscriber Identity Module. Rather than a chip on the motherboard, iSIMs are integrated directly onto the SoC. SoC (system on a chip) integration is the technology that makes smartphones possible. Instead of a thousand little chips for things like the CPU, GPU, RAM, modem, and a bunch of other things, everything gets packed into one single do-everything piece of silicon. Individual chips require more space and power thanks to having to make motherboard traces to connect everything and having to deal with chip packages.

I’m still using an old-fashioned traditional SIM card, and while I’m sure going with eSIM and now iSIM is great from a simplification and power usage point of view, I feel like they’re both also about taking control away from the user and shifting it towards the carrier. It was a long fight to get rid of locked phones (mostly), but with eSIM/iSIM it seems locking devices down in more fine-grained ways only becomes easier.

I might be overreacting, but little red flags go up when I read about eSIM and now iSIM.

Cobalt Networks were one of the early pioneers in network appliance hardware and produced some of the first turn-key webserver boxes you could buy, founded in 1996 as Cobalt Microserver. Cobalt boxes are immediately identifiable from their distinctive deep blue plastic bezels starting with the 1998 Cobalt Qube 2700. The Qube used a 150MHz QED RM5230; these CPUs are part of QED’s R5000 family and we’ll talk about their architecture a bit later. They came with 2.1GB hard disks with later larger options, 10Mbit Ethernet, 16MB of RAM standard with up to 256MB supported, and a “console” consisting of a backlit rear-mounted 2-line LCD and control buttons (on later machines, but not the original 2700, a serial port provided an actual console if you held down a button during startup). A fair number of typical configuration tasks such as setting its IP address could be done directly from the panel and the rest were intended to be done through its Perl-based web console. They were designed to run Linux from the ground up and shipped with Red Hat using a 2.0.x kernel.

Cobalt’s network appliances were so exotic back in the day, and once they started hitting the used market, I almost pulled the trigger quite a few times. These days, they’re harder to come by, and their use is, of course, inherently limited now, but that doesn’t make them any less eye-catching.

The DSi browser uses Opera 9.50. There are no security mitigations whatsoever. Jumping to shellcode is back on the menu! Stack buffer overflows are viable. Exploiting use-after-frees, which are often common in browsers, is easier than ever. In fact, the DSi doesn’t even have an operating system, so there’s no kernel to exploit. Various system privileges are handled by the SCFG register. The browser has enough privileges to run most homebrew, but not enough to gain persistence across boots without another exploit.

Browsing on the DS was a nightmare – and Nintendo charged for it. Crazy how times have changed.

The JH7110 isn’t amazing. But it’s not bad, either.

I still wouldn’t recommend most people buy this board, unless you already know a lot about Linux and SBCs in general. That may change a year from now, but right now, this board isn’t targeted at the same market as a Raspberry Pi.

At around $100, and not being quite production-ready, I’m only recommending this board to people interested in exploring RISC-V for now.

This seems like an expected experience for a relatively new architecture that still has rather limited hardware and software support. When the first Raspberry Pi came out, the situation wasn’t much better either, so give it a few years and RISC-V will be in a better place in the market for sub-€100 single-board computers.

And while headlines might indicate the language had fallen into disfavor, the amount of COBOL in use continues to grow, with 800 billion lines running in production systems daily, according to a global survey conducted last year by enterprise software firm Micro Focus. COBOL is considered strategic by 92% of survey respondents, and over half said they expect their organizations to keep running their COBOL applications for at least another 10 years. 

I feel like COBOL is one of those things that can guarantee you a career. If you know COBOL, you will most likely find a job and have a good career future, but it’s probably not going to be anything sexy or anything that has the (albeit tiny) opportunity of making you filthy rich – but you won’t ever be without a job for long either.

Apple’s iPhone 15 series will officially only support USB-C accessories that have been certified by Apple’s own Made for iPhone (MFi) program, potentially limiting the functionality of accessories not approved by Apple, an established leaker has now claimed.

So you’re getting USB-C, but not really. Leave it to Apple to milk even something as mundane as this.

In the last three weeks, we also launched the new AI-powered Bing into preview for more than 1 million people in 169 countries, and expanded the new Bing to the Bing and Edge mobile apps as well as introduced it into Skype. It is a new era in Search, Chat and Creation and with the new Bing and Edge you now have your own copilot for the web.

Today, we take the next major step forward adding to the incredible breadth and ease of use of the Windows PC by implementing a typable Windows search box and the amazing capability of the new AI-powered Bing directly into the taskbar. Putting all your search needs for Windows in one easy to find location.

I feel like adding a glorified autocomplete that tricks people into thinking it’s a real artificial intelligence to the Windows taskbar is not exactly what Windows users are looking for, but I guess that services revenue cash register has to keep dinging. I’m getting major cryptocurrency, NFT, and web3 vibes from all this, and I can’t wait for the whole thing to come crashing down once again.

The merge request for landing the first of “many” parts of the Wayland driver for Wine was opened this morning. This is part of the effort of allowing Windows games/applications running under Wine to operate natively on Wayland rather than having to go through XWayland.

Excellent work.

I believe that learning MINIX is probably the best way to learn about operating systems. Until now, I have not been able to find a MINIX 3 project that allows you to compile the code that is referenced in the book Operating Systems: Design and Implementation (3e) (v3.1.0). It was tricky to get a reasonable development setup to make it possible for newbies like myself to learn from the book. This is an attempt to fix that and make it easy to browse, edit, recompile, and execute the code.

An easy way to get started with MINIX, the famous microkernel teaching operating system from the university I got my two degrees at – although I’m not entirely sure if that’s a ringing endorsement.
