I like the PostgreSQL version of the BSD style license. and if there is no PARTY1 (The University of California in the PG license), its even simpler.

Costco (US big box membership retailer) had Samsung 32" 3840x2160 monitor on sale for $319 this weekend. Bought one for my wife, its gorgeous.
has HDMI 2.0 and DP 1.4(?) inputs. on her Latitude w/ the usb c expander box, I had to use the DP port to get 60Hz, the HDMI port would only do 30Hz, awwwww. I had the DP cable already, so all is good.
a bigger screen would have to be farther away to minimize neck strain looking back and forth, so zilch for gain.
3 ton? my truck, a 2002 Ford F250, weighs nearly 4.5 tons(US) loaded, and its a 7.3L turbodiesel. yes, its 4 WD because sometimes I need to go off road, or drive over the mountains in the winter.
its primary function in my life is to haul our caravan on long road trips, while carrying my astronomy and music festival stuff (awnings, tables, chairs, in addition to telescopes, ice chests, water, propane). its secondary function is carrying my rather large telescope to local star parties along with the tall ladder and everything else I need, and generally haul anything else too big to fit into my wife's estate.
sigh, the /20 was the bastard stepchild of the system/360 lineup. it only has 8 16 bit registers, instead of the 16 32 bit of the rest of the 360 line, and its instruction set is very subset and incompatible. The /20 had 4-32KB of core memory, and you needed at least 12KB to run the DPS OS which wasn't very compatible with anything else in the 360 lineup. its a shame its not a 360/40, those could at least run the mainstream DOS/360
restoring that thing to full operational state is likely going to be a major project. they used DTL logic, and ceramic hybrids rather than integrated circuits, which IBM called SLT. The DTL logic can be either 0-3V or 0-9V. I know a retired guy who restored an IBM 1130 of the same generation a couple years ago, it was about a 2 year full time project to get it fully functional. Part way through it, the front panel lights started dying of old age, and they were an unobtanium 'grain of wheat' lightbulb, so he ended up having to engineer and fabricate a LED based front panel replacement
Early Monday morning of my last week at work before retiring, I get a panic call from someone in corporate IT who'd heard I knew PostgreSQL. Apparently there was this PC in a wiring closet, running some sort of ancient linux and a bodge of proprietary crapware that used a Postgres database, it had been powered down to move it and change its UPS, and it wouldn't come back up.... It ran the card reader and turnstile for the garage security gate. They had the logins for it, so from home over the VPN I was able to log into the box, poke around, wow, this is some old stuff, Red Hat Linux 6, an app written in perl by a Japanese firm, and a PostgreSQL 7.3 database... Anyways, it took me about a half day to figure out that someone had changed a postgres configuration file over a year ago but never restarted the database or the box, and the change they made was invalid so postgres wouldn't start. logging had been disabled, so there was no error logs to debug, thats why it took me 4 hours instead of 30 mins. wave magic wand, turnstile works again.
real beer has no lactose and is vegan inherently, as its just made from water, barley, hops and a bit of yeast. I prefer my brews with minimal to no adjuncts. ok, a bit of oatmeal in an oatmeal stout is OK whomever started putting chocolate and/or coffee in stouts and porters should be taken out at a dawn and summarily shot
first, there's LiFePo4 batteries which are far less likely to go up in a fire. These come in brick sizes up to 200AH per 3.2V (nominal) cell, or even higher. requiring far fewer cells means you need far less equalization circuitry,too.
2nd, these LiFePo4 batteries can be discharged 80% 2000 times and still have most of their capacity. lead acid batteries lifetime gets greatly shortened if they are discharged below 50%
3rd, they can be charged at insane rates, like 100 amps into that 200AH cell, linear til its full, so 2 hours to fully recharge. lead acid batteries require an absorption phase to achieve a 100% charge that often takes 6-8 hours.
hmm, one of my pi3's is in a nice alloy case that has a heat spreader pressed against the CPU chip.
now, my workload for it is very light weight, it runs a python script that sleeps for 2 minutes, then reads some weather data and updates a couple servers. so it runs very cool
ah, they have a pi4 version now...

used to be a MANMAN system.
first version of Oracle, we extensively customized it to match our existing business processes, took a couple years., finally went live, was quite clunky.
we skipped a major release and when we went to the next release, we redesigned our processes to follow the default model of Oracle, and were live in 6 months. sure, some people in purchasing, AR, AP, etc had to be retrained to the new workflow but that wasn't that hard.
I recently had OWASP brought to my attention, someone was trying to use their security hardening guidelines for the postgresql database server... trouble was, that guide was written 10 years ago and hasn't been updated, while postgres has undergone steady and constant enhancement, with a major release about every 18 months, minor releases every month or two...
...cryptomining.
a moderately popular web forum I'm on currently is infested with some sort of trojan that as long as you've got the site open, it eats 100% of one CPU core, and taps a WebSocket at a .ru host every few seconds with a encrypted message/response ... googling the .ru host name shows it on various lists of coin miners.
natrually the javascript coming out of the site's advertising farms is way too obfuscated to trace, 180K blobs of hash being executed
death to spammers!
no interest? I'm 63, and I use Spotify extensively. My collection of 1000s of CDs is collecting dust. wrangling my MP3 'rips' onto various player platforms was getting just too annoying.
now, my FAVORITE way of listening to music is live, at concerts, primarily at places where listening is the norm as opposed to partying/drinking/yelling.
this was a city street, not a highway. 3 lane one way streets, quite frequently the left lane is full stopped because someone up ahead is making a left turn and waiting for pedestrians, are you saying the other two lanes have to stop and wait for the left lane to move before they can proceed? HAHAHAAHAHAHHA, right.
battery backup (or on newer RAID controllers, flash backed writeback cache using supercaps) only protects the write cache in the RAID controller. we're talking about write cache on the DRIVES, whihc is something desktop drives often have in write-back mode, but server drivers should always be write-through.
amazon's own webpile couldn't deliver my order history a hour ago....
I love the CIO's that mandate all internal critical systems are running on high availability high grade hardware, with redundant fiberswitches, multipath network connections, san storage, etc, then decides its all too expensive so outsources things to the likes of Amazon and Google, who are using the *cheapest* of commodity hardware they can get away with.... The irony of this escapes the suits.
1st, Chinese off-brand (UltraFire, etc etc etc) 18650s that claim 3700 mAH or whatever rarely even have 1000mAH. I've tested several batches of these and found no more than about 800mAH discharging to the 2.5V minimum safe voltage at a one hour discharge rate.
2nd, ANY device like this should be using the slightly more expensive PROTECTED 18650, NOT the unprotected ones. these usually have a button on the + end instead of a recessed contact, and are slightly longer. Unprotected LiIon batteries are only safe if they are permanently installed in a system with a integral protection circuit. the protection circuit prevents overcharge, over-discharge, and limits the max current output.
