Blame the fuckers who leave permanent markers right under the white board. I recall three occasions where this happened to me. By now a check all markers every time and move the permanents as far away as possible.

Morbid curiosity, oh yes. From his early art:

"It's gotten SO BAD with Linux and C/C++ our company said screw this and went ahead and developed it's own Windows 10-like OS shell and remade the command line interface of Linux to PROPER ENGLISH! We remade LAMP into custom Windows 2016 server-like environment with a decent Active Directory WAN/ALN management system analogue!"

and

Windows

I was prepared for some culture shock, being a command-line person. I was not prepared to thinks breaking without any interaction whatsoever (just leaving the thing on for five minutes unattended). I was aware of intrusive pop-ups, but not the sheer insanity of going through it. I had hoped Win10, at least while doing literally nothing, not being a total resource hog. The machine was set up by people really knowing what to do, therefore I assume there was no silly mistake with install and setup.

After avoiding MS Win since version 3.1 I now have to use a Win10 Laptop for my remote lectures. Killing myself now indeed seems to be a thing worth consideration. I always though our bombastic bob is way over the top when it comes to Win10 and MS software. He is not.

The best solution is to stop that sub-sub-sub-contractor shite going on. The owner of the meat processing plant said he didn't know who was working in his plant, the workers said the did not know who employed them. Crap like that absolutely has to stop. Similar things happen on construction sites.

As far as I can tell this is pretty rare (I myself do not own a smartphone). People who do not have one are most often very old people who are not likely out in the street. IIRC the owner rate if 95 percent in the "not a small child and not yet retired" bracket.

The problem is *much* more in the installation numbers. Still, even a non-perfect percentage will lead to alarms when the virus hits those with the app. 30 million (or even more installs) would be great to have.

Relocating office...

New monitors had to be bought anyway. Flat screens still a new thing and somewhat expensive. So management opted for (rather big) CRTs. New site near rail roads, so all CRTs where flickering like hell whenever a train passed, and that was all the time. And there is no practical way to stop the flickering (shielding with a thick iron box not being practical). CRTs were sold off for pennies, and flat screens bought.

Re: On speed

Long division is O(n^2), Newton iteration with FFT-multiplication is roughly O(n*log(n)). Contrary to folklore the overhead for the latter is not anymore big. With 10k-digit numbers just forget about any O(n^2) algorithms!

OK, tested it. Computing a square root to 10^9 digits takes 50 seconds (for comparison, computing Pi takes 32 minutes). Needs quite some RAM, of course.

Some write-up by myself is in Part 4, "Fast Arithmetic", of the book, Matters Computational (Springer, 2010). For final version see bottom of that page.

Re: On speed

WIkipedia list of arbitrary-precision arithmetic software. For the indicated problem (real numbers), I'd suggest to look at MPFR.

For the speed claims I made, computing Pi to 10^6 decimal digits using Pari/gp takes 400 millisecs on my (pretty decent) system.

No, rather implement FFT multiplication and use Newton inversion for sqrt.

Re: On speed

What, 50 minutes? That is spectacularly slow. Just tried with Pari/gp, which takes less than one millisec:

*** last result computed in 0 ms.

50 minutes should be more than enough for billions of digits.
