• Got Threadripper servers #2 and #3 deployed today.  Working names are Alvin, Simon, and Theodore.
  
  This weekend will be a clusterfest - LXD, GlusterFS, Percona XtraDB, MongoDB, Redis, Elasticsearch, RabbitMQ.  Plus a new Ethereum node, PostgreSQL, GitLab, Traefik, and Minio.
  
  
  
• Also got a delivery slot before the toilet paper went out stock again.  It's for Sunday, which is sooner than I need, but I'll take it.  (Some other items went out of stock while I was clicking refresh, including the very nice gluten free brioche, but I'll live.)

• Australia's NBN is looking at millimetre wavelengths for fixed wireless internet.  (ZDNet)
  
  This range - from around 25 to 30 GHz - is unattractive to for mobile phones but offers a lot of potential for things that don't move around quite so much.  If all the bandwidth is allocated for a given area, aggregate transfer speeds would exceed 100Gbps.  This makes it far superior to satellite for providing broadband internet to the home in semi-rural areas.
  
  
  
• Google has made Stadia free for the next two months.  (Thurrott.com)
  
  This will delay Stadia's inevitable demise by at least a week.
  
  
  
• Windows file explorer is getting WSL integration.  (The Verge)
  
  Good.  When I need that I tend to create folders the Windows side recognises and then symlink them into the WSL environment.  That works seamlessly.  The other direction.... Not so much.

• I downloaded Nim and installed it on WSL and compiled a trivial test application and...  It worked.  Completely painless.  Compiles in roughly a second, most of which is spent loading the compiler because WSL is kind of slow at initialising binaries.
  
  The compiled size for a trivial app that just reads some text from the user and responds is 90K.  75K stripped, 41K upxed.  (upxed binaries don't work on WSL1 though.)
  
  That's pretty acceptable; I'll rewrite my Crystal system monitoring agent in Nim and see how it goes with a simple real-world app (it needs, for example, HTTPS support).  On advantage I'm hoping to see from the C back-end is a smarter linker than Crystal has.
  
  The problem with using either one seriously at my day job is the state of the MongoDB drivers, since we have many terabytes of MongoDB databases we aren't about to migrate.
  
  Both come with MySQL and PostgreSQL drivers, and Elasticsearch is a REST API and therefore not a problem, but we need solid MongoDB support.
  
  Update: With the HTTPClient and SSL libraries pulled in - and working, since I had it actually download this page - the binary is 287K in full or 97K stripped and upxed.  That is entirely acceptable.  It's an order of magnitude smaller than the Crystal equivalent.
  
  Update Two: Wait, is that really a static binary? My usual test is to drop it on a horribly out-of-date Linux box and see if it still works, but I just turned off all of those.
  
  The documentation suggests that Nim builds static libraries by default, but that's awfully small if it's really pulled in OpenSSL.  I suspect that it might be "static except for OpenSSL" or some such nonsense.  But then, that's pretty much what Crystal does on Mac.

• So in what sense is OpenVMS open?  (Legacy OS)
  
  The final hobbyist licenses for OpenVMS will expire at the end of 2021.
  
  
  
• A look at the Xeon 5220R.  (Serve the Home)
  
  Wait, didn't we just do that one?  Oh, that was the 6226R?  Okay.
  
  This is a 24 core Xeon at a sharply reduced price compared to last year, as Intel struggles to find a way to compete with AMD.  And mostly fails, to be brutally honest.  It's beaten soundly by the 24 core Epyc 7402, and in many cases, by the 16 core Epyc 7302.
  
  Where the 6-series supports up to four sockets, the 5-series only supports the more common two.  Although the 6226R also only supports two sockets, so there's not a huge difference here.
  
  In short, it's a much more cost-effective chip from Intel if you're stuck with Intel.  If you're not stuck with Intel and don't need a ton of RAM per sever, there are faster better cheaper options.

• We have two more Threadripper servers being configured at my day job. 
  
  I'm going to set them all up as an LXD 4.0 cluster.  We're probably going to need Docker, which is not exactly best friends with LXD, but with LXD 4.0 I can run a full virtual machine and then run Docker inside that.
  
  72 cores at up to 4.5GHz, 384GB RAM, 45TB of enterprise MLC NVMe SSD, and 48TB of spinning rust across three servers.
  
  I could have gone for the 3970X, but I don't think we need those extra cores, and the price difference will pay for a nice little dev server - probably a Xeon 2276.
  
  
  
• Yes, we don't like Fox News.  No, that doesn't mean this lawsuit against them is anything more than goat vomit.  (TechDirt)
  
  This is why TechDirt remains sort of worth reading.  On the third hand, they note:

  The San Diego article has quite the interview with Arthur West, who runs WASHLITE, and it feels like every word he said is designed to troll Ken "Popehat" White

  Which seems laudable to me.

• The stupid you will have with you always.  (Tech Crunch)
  
  In this case it's almost certainly moderately stupid grifters shaking down the truly stupid, but the result is the same.
  
  
  
• This video will die in 100 days.
  
  
  
  
  
• AMD, could you release another CPU please?  The last one gave me content for days.
  
  
  
• Crystal 0.34 is out.  (Crystal-Lang)
  
  Not a lot of language changes; things are getting more stable as they approach 1.0.  They have tidied up some features so that, for example, a case statement will detect whether you are checking all the possible values and refuse to compile if not.  You can include an else condition as a catch-all, but you have to do that explicitly.
  
  I like Crystal, and I like the direction it's headed in.  I need to catch up on Nim as well and see where that is, because I'd like to be able to deploy to Windows and Crystal won't be there for a while yet.
  
  
  
• Mochizuki's inter-universal Teichmüller proof has been published.  (Phys.org)
  
  Mathematicians are still debating whether it actually is a proof, and Mochizuki and Teichmüller themselves aren't being terribly helpful.
  
  This - if it is validated - would prove the abc conjecture, which would in turn prove a whole bunch of stuff, including a much simpler proof of Fermat's Last Theorem.  (Which has been proven, but is fiendishly complicated.)
  
  
  
• The hot new game for 2020 is finding a time when your supermarket both has toilet paper in stock and has delivery slots open.
  
  Right now it's a but not b.  Earlier it was b but not a.
  
  I went out yesterday - I needed to resupply on antihistamines, because if my allergies started playing up and I was sneezing all the time I wouldn't be able to go out in public - and not only was the toilet paper aisle empty, the toilet paper aisle was gone.  
  
  Lots and lots of nappies where it would have normally been.  If you're a tiny baby - or elderly and infirm, I suppose - you can continue pooping on your regular schedule.
  
  I have groceries arriving tomorrow morning between 4 AM and 9 AM, which is a time slot that didn't exist in pre-apocalypse days, though the ETA is between 6:50 and 7:50 which is not entirely insane.  If I get what I ordered or some reasonable facsimile I'll be good for three weeks.
  
  Food I already have.  There's no shortage of food.  Food is goddamn everywhere.
  
  Except somehow Easter eggs, but I bought some yesterday so that's okay.

• Novartis is starting phase 3 trials of ruxolitinib to treat severe Corona-Chan.  (Novartis)
  
  This is a treatment for cytokine storms, which are believed to have been a major killer during the 1918 Flu Pandemic - the reason it killed so many young and otherwise healthy people.  I'm not sure how common that is in WBSDP, but it's a good drug to add to the toolbox - if it works.
  
  Also, ruxolitinib is binitiloxur backwards.
