You Shall Go To The Ball Edition
Tech News
- Flink 1.8.0 is out.
What is Flink? I don't know. I read "What is Apache Flink?" and I still don't know.
- Intel has announced - sort of - the Xeon Gold U series. (Serve the Home)
This includes a 20 core server processor for around $1000 - the 6209U - which is amazing value compared to other Intel server parts, but only supports single-socket motherboards.
It replaces traditional configs with two ten core CPUs for much less money - the same configurations AMD has targeted with its 24 core Epyc 7401P at $1075. Intel's advantage is that it has higher boost clock speeds - 3.9GHz vs. 3.0GHz on the Epyc. AMD's advantage is it offers vastly more I/O - 128 PCIe lanes vs. just 40 on the Xeon.
Supermicro are ready and waiting with their X11SPA-TF motherboard. It's focused more at workstations but has onboard BMC so it's fine for servers as well. Single socket LGA3467, 12 DIMM slots (up to 3TB RAM), 4 M.2 slots, 8 SATA ports, gigabit and 10G Ethernet (both RJ45), plus another port dedicated to IPMI.
- Doing what the DOJ won't: Apple may be breaking up iTunes. (Six Colors)
Much of iTunes' terribleness comes down to it saving all your metadata in a single huge XML file rather than using a database the way any even vaguely sane person would.
- Intel's H10 SSD is a piece of garbage that no-one should buy. (ZDNet)
It puts up to 32GB of Optane cache together with up to 1TB of QLC flash. So far so good. A small amount of high-performance, high-endurance Optane backed by lots of cheap QLC flash. What's not to like?
What's not to like is that this is not a single device. It is two separate devices - a tiny useless Optane drive and a large, slow QLC flash drive with no integrated pseudo-SLC cache. It only actually works if you have an 8th or 9th generation Intel CPU and RST support.
Another two generations and they might actually get it right; for now just get the Intel 660p for fast bulk storage (~$100 per TB) or the Samsung 870 EVO Plus for high-speed storage (~$250 per TB).
Social Media News
- Facebook accidentally outs Big Brother. (Business Insider)
Oops.
- Trust no-one. Block everyone. (TechDirt)
The truth isn't out there.
Crystal Ballroom
- Crystal has an issue that prevents you from building static binaries on MacOS. Or so it seemed. Turns out that MacOS has an issue that prevents you from building static libraries on MacOS: Some system libraries have no static version, and can only be dynamically linked.
You can however build a portable Mac binary with Crystal that includes everything except the system libraries, and will run on any sufficiently recent version of the operating system.
So that lets me run on any version of Linux (3.9 kernel or later for full functionality), and on Mac. Currently I have a problem even on WSL let alone directly on Windows, but we'll see about that.

You appear to have two copies of this post.
Also, my hard drives showed up this afternoon! I now have 2x4TB WD Reds in Synology's SHR (shared hybrid RAID, whatever that is, but it's sort of striping.) The little bit I've used it seems nice. Thinking about picking up an extra 4GB of RAM for it, although I don't know if that's necessary or not.
It comes with Node.js.

Something must have hiccuped during saving. I noticed an edit didn't get applied but I didn't notice the extra copy which was why the edit didn't apply.
It sounds like SHR is like what Drobo does - it lets you add drives at any time to expand, even if not all the drives are the sames size.

You'll only need the extra RAM if you run a lot of apps. The resource monitor on my Synology NAS shows that it's never used more than 20% of its 8GB memory in the past year, and that's with Drive, Note Station, Hyper Backup, iTunes Server, Media Server, and Docker running 2-3 containers. If it weren't for Docker, it wouldn't even be at 20%.

Good to know. I see that Synology's branded RAM is 2-3 times what equivalent Crucial costs on Newegg.
For now I mainly plan to use this as just a file server & backup repository, although i let it install all the default apps. Not sure if I'm going to do anything with Docker or not.

I like that there's a setting to dim the front-panel LEDs, too. I was afraid I was going to have to tape over the power LED.

Don't buy their branded memory (or, for that matter, their 10G card or NVMe SSD cache drives); I just bought Crucial. Works fine. A bit of googling will turn up a tested third-party hardware list.
My primary use for Docker is Kallithea, which I use for hosting my private Git and Mercurial repositories. I also generally have a DB and some application containers running.

What DB, and, just out of curiosity, what apps?
I assume the underlying OS is Linux of some type.

Whatever DB is best supported by the apps; the nice thing about containers is that for a single app hidden behind a firewall, I don't have to fool around installing/configuring/managing it.
No particularly interesting apps running right now, but most of the containers have been built on Alpine Linux, because it's nice and small. My most-used Docker container actually runs on my Mac: waifu2x, built on an Ubuntu base. I have a custom dockerfile for it that's a lot smaller than the ones I've found online.
