Personal computing on an Amiga in 2021

Solène created a week-long personal computing challenge around old computers. I chose to use an Amiga for the week. In this issue I write about my experience, and what modern computing lost when Commodore died. I also want to show some of the things you can do with an Amiga or even an emulator if you’d like to try. I’ve tried to get into the Amiga-like operating systems – MorphOS, AROS, Amiga OS 4 – but the platform just doesn’t suit me. I find them convoluted, incomprehensible, and frustratingly difficult to use. Not that it matters – I’m not here to ruin the Amiga community’s party – but if they want to sustain that community instead of having it die out as their user numbers dwindle due to old age, they might want to consider making their operating systems a little less… Obtuse.

Apple’s plan to “Think Different” about encryption opens a backdoor to your private life

Apple has announced impending changes to its operating systems that include new “protections for children” features in iCloud and iMessage. If you’ve spent any time following the Crypto Wars, you know what this means: Apple is planning to build a backdoor into its data storage system and its messaging system. Child exploitation is a serious problem, and Apple isn’t the first tech company to bend its privacy-protective stance in an attempt to combat it. But that choice will come at a high price for overall user privacy. Apple can explain at length how its technical implementation will preserve privacy and security in its proposed backdoor, but at the end of the day, even a thoroughly documented, carefully thought-out, and narrowly-scoped backdoor is still a backdoor. Basically, Apple is going to scan your iCloud photo library, and compare cryptographic hashes of your photos to known photos containing child pornography. It’s hard to argue against this because it makes it seem as if you’re arguing against catching the sort of people that have such material. However, the issue with tools like this are not the ends – all of us are on the same side here – but the means. It’s more than obvious that this scanning is a gross invasion of privacy, but at the same time, you could easily argue that this is a bit of privacy we’d be willing to give up in order to aid in catching the worst elements of our society. The real problems stem from the fact that tools like this are simply never going to be foolproof. Software is incredibly unreliable, and while a random application crashing won’t ruin your life, an algorithm wrongfully labeling you as a pedophile most definitely will. On top of unintended consequences, malicious intent could be a major problem here too – what if some asshole wants to ruin your life, and sends you compromised photos, or otherwise sneaks them onto your device? And with Apple’s long history of working very closely with the most horrid regimes in the world, imagine what governments can do with a tool like this? On the ends that Apple is trying to get to here, we are all on the same side. The means to get there, however, need to be carefully considered.

ReactOS improves amd64 support

The latest ReactOS newsletter has been published. Timo Kreuzer (tkreuzer) worked hard on various parts of the kernel and HAL, fixing issues here and there. Structured Exception Handling (SEH) support for the amd64 architecture was finished, various bugs around the kernel are fixed. A major issue with interrupt handling in HAL was also fixed in May, which finally allowed a semi-stable boot in a virtual environment. There’s also work being done on support for multiple monitors, improved support for SMP, and more.

Google drops supports for Google services for Android 2.3.7 and lower

As part of our ongoing efforts to keep our users safe, Google will no longer allow sign-in on Android devices that run Android 2.3.7 or lower starting September 27, 2021. If you sign into your device after September 27, you may get username or password errors when you try to use Google products and services like Gmail, YouTube, and Maps. Android 2.3.7 was released on 21 September, 2011. That’s ten years of support. I think that’s fair.

Google unveils Pixel 6, with Google’s own SoC

Google is announcing the Pixel 6 and Pixel 6 Pro today, though it might be better to call it a preview or a tease. Rather than releasing all the details on its new Android phones, Google is instead putting the focus on the new system on a chip (SoC) that will be inside the new Pixels. It’s called the Tensor SoC, named after the Tensor Processing Units (TPU) Google uses in its data centers. Tensor is an SoC, not a single processor. And so while it’s fair to call it Google-designed, it’s also still unclear which components are Google-made and which are licensed from others. Two things are definitely coming from Google: a mobile TPU for AI operations and a new Titan M2 chip for security. The rest, including the CPU, GPU, and 5G modem, are all still a mystery. Less mysterious: the phones themselves. I spent about an hour at Google’s Mountain View campus last week looking at the phone hardware and talking with Google’s hardware chief Rick Osterloh about Tensor. After all that, my main takeaway about the new Pixel 6 phones is simple. Google is actually, finally trying to make a competitive flagship phone. This looks like a really premium product, and it will most definitely have a price to match. Google finally switching over to its own SoC, after years of relying on Qualcomm, which is technically great for competition, but much as with Apple’s chips, it’s not like anyone else is really going to benefit from this. Assuming Google plans on selling this new Pixel in more than three countries, and assuming the claims about the cameras are backed up my real-world reviews, this will definitely be my next phone, since my current smartphone is ready for replacement. And what a surprise – smartphone camera quality suddenly matters now that I have a kid.

AMD and Valve working on new Linux CPU performance scaling design

It’s no secret that the ACPI CPUFreq driver code has at times been less than ideal on recent AMD processors with delivering less than expected performance/behavior with being slow to ramp up to a higher performance state or otherwise coming up short of disabling the power management functionality outright. AMD hasn’t traditionally worked on the Linux CPU frequency scaling code as much as Intel does to their P-State scaling driver and other areas of power management at large. AMD and Valve have been working to improve the performance/power efficiency for modern AMD platforms running on Steam Play (Proton / Wine) and have spearheaded “ was not very performance/power efficiency for modern AMD platforms…a new CPU performance scaling design for AMD platform which has better performance per watt scaling on such as 3D game like Horizon Zero Dawn with VKD3D-Proton on Steam.” Valve has single-handedly made Linux a viable choice for people who play games, and with the Steam Deck on its way, their efforts are only going to ramp up. They’re doing this for their own bottom line, of course, but this is one of those cases where a corporate interest lines up perfectly with a consumer interest.

Remembering Radio Shack’s Windows competitor: Tandy DeskMate

In the 1980s, Radio Shack parent Tandy Corp. released a graphical user interface called DeskMate that shipped with its TRS-80 and Tandy personal computers. It made its PCs easier to use and competed with Windows. Let’s take a look back. I’ve never used DeskMate – or Tandy computers in general – but there was a whole (cottage) industry of DOS graphical user interfaces and alternative Windows shells during the 3.x days, most notably Norton Desktop. If you ever have an empty weekend you want to fill up- fire up a DOS or windows 3.x virtual machine, and go to town. You can easily lose days researching this particular technological dead end.

WireGuardNT: a high-performance WireGuard implementation for the Windows kernel

After many months of work, Simon and I are pleased to announce the WireGuardNT project, a native port of WireGuard to the Windows kernel. This has been a monumental undertaking, and if you’ve noticed that I haven’t read emails in about two months, now you know why. WireGuardNT, lower-cased as “wireguard-nt” like the other repos, began as a port of the Linux codebase, so that we could benefit from the analysis and scrutiny that that code has already received. After the initial porting efforts there succeeded, the NT codebase quickly diverged to fit well with native NTisms and NDIS (Windows networking stack) APIs. The end result is a deeply integrated and highly performant implementation of WireGuard for the NT kernel, that makes use of the full gamut of NT kernel and NDIS capabilities. That’s an impressive porting job, and further spreads the availability of this protocol to entirely new users and settings.

IBM announces z/OS V2.5

IBM today announced IBM z/OS V2.5, the next-generation operating system for IBM Z, designed to accelerate client adoption of hybrid cloud and AI and drive application modernization projects. I have several IBM Z mainframes running in my garage running our family’s Minecraft server. This update will surely lead to downtime, which is a major, major bummer, especially since IBM is shoving ever more ads into z/OS to get us to subscribe to IBM Music.

Linux 5.14 drops old DEC Alpha-specific binary loader used for x86 binary emulation

As a weekend blast from the past, the Linux 5.14 kernel saw some Alpha CPU architecture updates — including various fixes and the removal of an Alpha-specific binary loader for running a decades dated x86 software emulator. While past the merge window, the Linux 5.14 code this week has dropped “binfmt_em86” from the kernel. This is an Alpha binary loader for Linux focused on running i386/i486 binaries via the EM86 emulator in user-space. This was part of the effort for allowing Intel Linux x86 binaries back in the day to run on DEC Alpha hardware. How will I run x86 Linux binaries on my AlphaServer ES47 now? What a preposterous commit. Linux is definitely going down the drain.
