The Year Of The Eternal Two Weeks Edition
- I tried out the Aria storage engine to see if it worked better than InnoDB for large working sets relative to memory, and it turned out the answer is no.
Which is good because I didn't want to use it anyway. While Aria (unlike MyISAM) is at least crash safe, it doesn't improve on MyISAM's write lock behaviour, which is frankly terrible.
It's not a problem for the search index, because by design that uses a single asynchronous writer.
- I'll run a scaling test on a 32GB dedicated server today. It's really nice that I can spin one up for 18¢ an hour and then just shut it down when the test is done.
- Now that the US election is all over bar the screaming, Facebook is permitting political ads again LOL J/K. (The Guardian)
Facebook is extending its ban on political advertising for another month, because it was never about protecting the integrity of the election.
- Nvida is also planning to release a feature like AMD's SAM. (Tom's Hardware)
This lets you map all of video card's VRAM into the CPU's address space rather than using a 256M window, and boosts performance by a few percent. Why this wasn't done before I'm not sure; it seems a no-brainer on 64-bit systems.
- Third-gen Epyc is on its way, at clock speeds up to 3.5GHz. (Tom's Hardware)
That's nearly as fast as my existing desktop, and has around 40% better IPC. And eight times as many cores.
- AMD just announced a new Ryzen Embedded lineup so where are the systems based on them oh there they are. (Tom's Hardware)
Pretty nice systems too. Six or eight cores, up to 64GB RAM with ECC support, room for one each M.2 and 2.5" drives, DisplayPort and HDMI, 1GbE and 2.5GbE network ports, two USB 3.2 Gen 2 Type A (that is, 10Gb), two USB 3.2 Gen 2 Type C with DisplayPort - though these are on the front so not ideal for connecting monitors, four USB 2.0, and optional WiFi. And a serial port, because these are for embedded applications.
And it's passively cooled.
They also offer the motherboards, which are NUC-sized 4"x4", if you want to build your own.
No retail pricing because again these are for embedded applications.
- MacOS Big Sur is out. (Apple)
How long before they manage to fuck everything up?
- Less than a day, as it turns out. (Tech Crunch)
Apple's Gatekeeper back-end broke down, which meant that Macs running recent versions of MacOS (I've frozen updates on mine for over a year now) could not start third-party applications. Any third-party applications.
Response of the world's richest company:
If you rebooted your Mac during this outage the problem would go away because the operating system would never finish rebooting.
Apple's ongoing infantilisation of their operating system is why I'm never going to buy another Mac.
- So, if you can't run third-party Apps because an Apple online service broke, that means that Apple is tracking every third-party app you run, right?
And that's not the half of it. (Sneak.Berlin)
They transmit all this information through a third-party CDN - Akamai - UNENCRYPTED.
Previously, you could monitor and even block this nonsense with apps like Little Snitch. Big Sur no longer allows Little Snitch to run. And while it still supports VPN software, Apple apps and operating system functions will simply bypass the VPN.
Oh, and those new Arm-based Macs? You have no option to run anything but Big Sur. Because fuck you, that's why.
- We now live in a timeline so thoroughly messed up that Microsoft are the good guys.
- The 6800XT is an overclocking monster unless it isn't. (WCCFTech)
Reportedly it can hit 2.5GHz while keeping within stock TDP.
- It were ever thus.
Totally Not Tech News
- Washington Post: There is no Deep State.
Also Washington Post: LOL the Deep State lied to elected officials.
- The fascists at CNN of course think this is a wonderful jape.
War, what is it good for?
- Twitter rando whose account has since gone private so that no-one can see it tweeted at Target that a book made them feel unsafe.

And if you remember the old realplayer garbage, if you tried to firewall its normal communication ports it would just shift over to using 80.

We did it at Ooma because certain ISPs like to redirect your traffic by returning phony DNS results, and our devices couldn't come online if they weren't talking to a server with the correct SSL certs.

How's that going to work if the router drops all packets from that host? (I know, locking you out of the OS or something.)

Depending on how the phone home works you might find someone writing a server process that can run on routers that simply always returns the equivalent of "yep, go ahead & run this."

Basically, it's whack-a-moles all the way down, and while Apple won't spend a dime on QA or building reliable Internet services, they're eager to invest in converting their products into walled gardens that grow only RPU.
(why, yes, I've bought my last Mac, and it will never be upgraded to Big Sur; if that someday breaks interoperability with my phone and watch, I'll replace those, too. If I weren't living under the threat of Harris becoming President in January, I'd be ready to drop a few grand on a high-end Windows laptop; WSL2 is good and getting better)

True. Since I haven't really looked into pfSense yet, but am getting closer to doing so, I have to wonder how hard it would be to just have something like a cron job that runs every hour or so and does a GetHostByName(), gets the h_addr_list out of the returned hostent, and blocks all of those IPs (or some more modern equivalent for any piece of that) again, on a router. One of those cute, cheap U-series-powered computers with multiple NICs you can get on Aliexpress ought to make a nice filter.
I certainly agree there's a level of whack-a-mole that you could theoretically end up in. Depends on how many people blocking them it would take for Apple to escalate each time.
