- Pre-EOFY craziness and post-EOFY reports are all done. Free at last!
- The chief competition for QLC SSDs is DRAMless TLC models. Removing the DRAM does hurt performance, but saves money, and TLC is faster and more reliable than QLC.
The Crucial P2 is one such, an update over the earlier P1. (Tom's Hardware)
Reads on the P2 are actually slower than the P1, but writes beyond the pseudo-SLC cache have improved dramatically. 450MB/s sustained might not match a Samsung 970 Pro - or even a 970 Evo - but it's hardly slow.
- A leaked benchmark of Intel's upcoming Core i7-1165G7 suggests it is up to 20% faster on single-threaded benchmarks than AMD's current Ryzen 7 4800U unless it doesn't. (WCCFTech)
Still slower on multi-threaded workloads, to no-one's surprise; even constrained to a 15W envelope an 8-core part is going to kill a 4-core part.
Of course, AMD is preparing to release Zen and Ryzen 4000 desktop and Ryzen 5000 APUs, so Intel will not likely maintain this lead for long.
- Don't knock it, it works.
- Re-examining the Blub Paradox. (C2)
Of course in the sense of Turing Completeness, all programming languages are equally powerful; they vary in degree of expressiveness.
- Why larger virtualisation nodes are better. (Serve the Home)
This is why we went with Threadripper servers for our new cluster at my day job, instead of a larger number of smaller Ryzen servers. If I need to throw 24 cores and 128GB of RAM at a single task, I can, without needing to farm it out across multiple servers.
Warning: Do not read this while hungry.
- 23,000 MongoDB databases left exposed online have been hacked and are being held for ransom. (ZDNet)
MongoDB doesn't force you to create an admin password by default, but it does yell at you until you do so. And by default it only binds to localhost and isn't available on the public network at all.
Which makes me wonder about AWS NAT. If you bind a database to the private IP, is NAT making it publicly available by default, since AWS instances don't have explicitly bound public IPs the way classic virtual servers do? This still wouldn't expose MongoDB by default, but seems troubling.
I should look into that, though I don't really use AWS much. Apart from Route 53 at work, where we have about 170 domains that need rock-solid DNS. AWS has probably already thought of and dealt with this, but it's something I should know.
- The Windows Alt-Tab function to cycle through all your open applications will also cycle through every single Edge tab. (The Verge)
Of course, you can prevent this by not using Edge. Once you manage to get the blasted thing to close. Yeah, I just got the latest Windows update.
- Facebook is shutting down Lasso and Hobbi. (Tech Crunch)
Never heard of them? That's why.
- Apple stores are closed again. Louis Rossman hardest hit. (9to5Mac)
As Louis would say, Die, Corona, die!
Disclaimer: So that's it for today and as always, I hope you've learned something.

The last time I created an AWS instance with the default security policy, it blocked everything but inbound SSH, with sshd configured to require the supplied key. I don't even think you get ICMP by default.

Most browsers that I'm familiar with that have a tab-switching key-binding use Ctrl-Tab. Why would the idiots at MS (who are just reskinning chrome, ffs) bind it to a window manager binding? I mean, it's even their own damned window manager binding they're clobbering.
Oh, right, idiots gonna idiot.

Thanks J, that makes sense.

Hell, they forced Edge on to my Win7 machine and forced it to reboot overnight. And once I logged it it pushed me into a setup your Microsoft Account screen with no normal exit or cancel.
(I cancelled and uninstalled Edge immediately thereafter.)

Yeah, the Edge install is absurdly aggressive.

That second item, I feel like I was reading the text to a new version of the Turbo Encabulator spiel. Almost every other word an acronym, wow.

It makes spell-checking these posts basically useless. If I turn it on I just get a sea of angry underlines.

Remember three years ago when you could have two cores in a laptop?
I'd love something like the Zephyrus G14 or maybe that LG linked here the other day (but I'd prefer that to have TB so I could put an eGPU if I was feeling crazy) but my Spin 5 from a couple of years ago, with the quad core Kaby Lake refresh is still pretty decent, although obviously it's nowhere near as fast as my desktop.)
