vt240··on Apple Silicon M1: Black Magic Fuckery
Yes, can I please have System 7.1 or 7.5.3 back? I recently installed MAE on my SunBlade 2500 and it has been an amazing experience. A Classic Mac, without all the issues of HFS corruption from crashing out. Running 68k software at G4 speeds. Haha. For a lot of tasks it certainly works better than the Classic environment did under 10.1-4 since it's not targeting the System 9.2.
vt240··on Why do printers still suck?
Still running our LaserJet 5si on the network for 11x17 pages. Been out of service (maintenance contract) for years, but it's still working fine with some light cleaning.
vt240··on The software industry is going through the “disposable plastic” crisis
I'll just add at my current place with clustered Windows 2008 back-end, with AD and DFS, and distributed flash based , fan-less, Windows 7 embedded clients we've had zero down time in 8 years or so since it was implemented. End-Nodes provide serial data from the DFS shares to the machines. I'll grant you that is certainly easier than redundant real time control issues, a little bit. But. It's just all about planning for sure, on the software, hardware, and IT infrastructure end of it.
vt240··on The software industry is going through the “disposable plastic” crisis
Haha. Been there. Seen that. I do feel for you though.

A 24-hr restart plan, sounds like a properly documented quality management process for a large boiler? Disconnecting the "Windows XP box" is removing the control system correct? Not really the same thing is it? There's no reason the XP Embedded hardware platform could not have been engineered with high availability in mind? It's not as if there are no comercial-off-the-shelf options here.

The company who chooses to let the bosses son, who built custom PCs in high school, design the critical process control systems, is I'd say, outside the scope of the argument here.

The Wikipedia entry for FSO networking is pretty misleading. There have been commercial products on the market for quite a while.
vt240··on Big Sur on Unsupported Macs
For what it's worth, Windows 10 since 1809 has supported prompt-before-download for Windows Update, and corrected many of the other annoying "do as I want, not as I say," issues from previous releases.

vt240··on AVX-512 Mask Registers, Again
>To not be using at least SSE we're talking about software from before the turn of the century.

No, we're just talking about software, which was compiled targeting MMX/x87 code generation. It could have been made last week. Not that my original question really matters at all, asked and answered, but there are a whole host of other performance issues with mode switching from mixing libraries compiled for the various SIMD targets.

vt240··on AVX-512 Mask Registers, Again
Haha, I don't know if I buy that, since I've been around commercial EDA and ATE software, where you could have a decade of cruft and layered products to work on top of. But wider adoption of vendor tools such as MKL has certainly improved the issue.
vt240··on AVX-512 Mask Registers, Again
>Who is going to be making heavy use of x87 or MMX (both obsolete) along with AVX-512 mask registers? It seems extremely unlikely.

Wouldn't this be a performance issue if your linking an executable against libraries compiled for MMX, AVX.

vt240··on SCI Runs OpenVMS on x86-64
They wont because the PRODUCER value is wrong in the VSI licenses. But you are correct, that for most uses outside of commercial museum systems, its probably not much of an issue since there are license generators out there in the wild.

It is really unfortunate, that a community which has always been highly adverse to software piracy, would be forced into such a situation by HPE to maintain their hobby systems though. At this stage, VAX VMS being out of support for so many years, and having such little commercial value even under emulation, it just seems silly HPE does not issue a perpetual non-comerical license for VAX systems.

vt240··on SCI Runs OpenVMS on x86-64
They just can't do it due to licensing, without releasing their own VAX build of OpenVMS. That's not going to happen for obviously reasons.
vt240··on HPE sets end date for hobbyist licenses for OpenVMS
I am aware. But the community has always been pretty strongly adverse to that kind of activity.
vt240··on HPE sets end date for hobbyist licenses for OpenVMS
Unfortunately VSI will not be releasing any VAX processor support, so this will leave any hobbyists maintaining vintage systems in the lurch. From what I have seen, no one in the OpenVMS hobbyist community is really upset about this decision, except for the people maintaining VAX hardware. The expectation for those using Alpha and ia64 systems is that VSI will take up some kind of opensource developer license or hobbyist license before the current hobbyist licenses expire from HP.
vt240··on ICANN Delays .ORG Sale Approval
Has anyone looked at PIR's 990 Forms and has knowledge of business operations in the sector. It looks like from their expense sheet PIR contracts all of the actual management of the their TLDs to Afilias. What is the breakdown of responsibility here? What does PIR actually do?
vt240··on China’s vast fleet is tipping the balance in the Pacific
I started reading "India and China at Sea" [1]. Seems to be really well put together.

vt240··on How Boeing, FAA certified the suspect 737 MAX flight control system
The banner of the EAA website says they have a Full 737MAX simulator [1]. From this Press Release [2], it would seem they were rolling out in Oct, 2017.

vt240··on Pilots offer insights on Boeing 737 crashes
EA operates their feeder flight school [1]. There is a PR from EA somewhere showing his yearbook photo from their graduating class 2010, but again it was in the Ethiopian press, I forgot to outline it.

vt240··on Pilots offer insights on Boeing 737 crashes
EA has other 737 models in their fleet. Their last accident, a 737-800, ET409 [1][2] out of Lebanon, CRM issues were cited as the primary factor. Not arguing with you, and they could have addressed all the training problems. But I don't think the previous accident should be overlooked when speculating. Especially, the fact that EA was hostile to the conclusions of the report. [3]

But he had only been a 737 Captain since Nov 2017 [1]. And graduated from flight school in 2010. It's unknown what the distribution of the 8000 hours are. For all we know, he had 6000 hours on the Q400.

vt240··on Oft-quoted paper on spread of fake news is retracted
I really don’t believe it’s fair to call journal articles or letters published in peer-reviewed academic journals, “Fake News” if they turn out to be wrong, or if the authors retract the paper. Part of the larger process of scrutinizing scientific research, is the interactions among scientists, even with competing ideas, in such publications. Where I think we cross the bounds, into “Fake News” territory, is when, immediately upon publication in a Journal, a University PR department, pushes out a release to all the media, often with WILD claims, not representative of the research itself. Or publications such as Scientific American, pick up the paper, and push out a poor Laypersons analysis, without any critical review.
vt240··on Microsoft Is Putting Ads on the Mail App in Windows 10
Occasionally, I still run into a piece of software which makes me yearn for the days when I built my own /usr/local from source. But as the repos have got better, this is getting to be a rare event. I still don't like the feeling of being boxed into the package management system. And the extra level of complication trying to manage issues from building software from source which reference package managed libraries and other dependencies.
vt240··on Microsoft Is Putting Ads on the Mail App in Windows 10
Employer was supposed to be using Windows deployment tools to create custom enterprise images... But I'm stuck in the same boat. The maintenance overhead is too much for a small business. I am very upset that the default enterprise image is full of crap-ware, and the only alternative was LTSB with no support for Edge or Windows Store.

Grainger [1] search for "industrial Blowers and Accessories" would probably be a good place to start looking. They tend to be expensive though. Take a look at McMaster-Carr [2] too.

vt240··on DNA Is a Fractal Antenna in Electromagnetic Fields (2011)
I was able to find one stumbling around google, if anyone else is interested. Lenovo X1 G3 from Sporton[1]. And a less comprehensive report from Intek, for 2016 random brand convertible [2].

What are the typical radiated power levels from a modern laptop over 20kHz-5.8GHz, excluding Wi-fi and other radios? Does anyone have any references to share, such as E/H spectrums of a typical modern laptop, which has gone through EM compliance testing?
vt240··on Interim OS: minimalist OS influenced by Lisp machines and Plan 9
I installed RDB last week on my hobby I64 machine. Although I had glancing encounters with VMS through work, it has been a lot of fun to explore some of the features of the OS in depth. I remember having a WinNT RDB eons ago too. But it seems to have disappeared from the web. The Internet Archive has a copy of "Rdb : a comprehensive guide" for loan if anyone is interested.
