Anyone have experience with ELK analysis toolsin containers, Kibana+elastic search?
Here's my problem in the forums for the software. If someone has experience with this, or has ever run ELK in docker compose, I would love it if you'd get in touch.

@Flyboy737_NG Cool; love it!
It would be great if this was also published somewhere off of twitter, where I very rarely go any more.
One correction: controllers for Airventure Oshkosh are specially trained and tested, from all over the country, but mostly from midwest.

@CountBinface @standupmaths I just saw Matter Parker's video on this. I just checked ebay; no one is selling one yet.
I would love to get ahold of one! Good luck with the election!

Every prospective MP needs a flyer. So here's mine. 48,000 of these beauties have landed in Richmond & Northallerton. Really. And unlike certain parties, my graphs have been fact-checked by a professional mathematician. #ToBinfinityAndBeyond @standupmaths

@MobaXterm Hey, I think that Moba Xterm isn't respecting file creation mask on a Linux system when I use the drag and drop file transfer tool. Is there any way to configure it to respect that mask?

@seacaptainpolls I think the joke was written by Amber! I would like the new sexy headshot, please. (Really, I just love Amber, and I'd love a headshot of her. She's funny and smart and awesome!)

@james_hashley One really big upside is as a pilot, you spend the majority of your time flying. Astronauts spend 98% on earth training.

My biggest dream as a child was to pilot the shuttle. I guess flying planes is an okay second. 🤷🏻♂️☺️

STS-1 – the first Space Shuttle mission – launched 43 years ago today from @NASAKennedy Space Center. The orbiter for STS-1 was the Columbia, which circled the Earth 37 times over the span of the 54-hour mission. The Shuttle program inspired a lot of Americans, particularly kids in the 80’s and 90’s, to get interested in space. I’m hopeful the next evolution of human spaceflight will help keep the inspiration alive!

Yeah; I've debated this a lot. I agree it's 95% a marketing term.
But.
You can kind of define an HPC problem as one that's so big that instead of being dominated by the CPU core speed, it's dominated by how fast you can move the data to and from the (aggregate) C(G)PUs.

I tried staying out of this nomenclature debate From an #HPC perspective, my 2¢ worth Since we can’t scale up sufficiently, it is a must to scale out for performance All supercomputers today are a cluster of interconnected nodes #HPC @ikirker @SamPartee @boborado

@Renard93801084 @Rainmaker1973 There were clusters of Sony consoles used for general-purpose computing, yes. Some of them may have been useful.
English
In 2010, the United States Air Force created the world's 33rd-fastest computer inside its own Air Force Research Laboratory, using 1,760 Sony PlayStation 3 consoles.
They called it the "Condor Cluster," and it was the Department of Defense's fastest computer.
The USAF put the computer in Rome, New York, near Syracuse, and intended to use the computer for radar enhancement, pattern recognition, satellite imagery processing and artificial intelligence research for current and future Air Force projects and operations.
Because a PlayStation cost $300 at the time, together, the PlayStations formed the core of the computer for a cost of roughly $1 million, 10% of the price of a conventional supercomputer.
The result was a 500 TeraFLOPS Heterogeneous Cluster powered by PS3s but connected to subcluster heads of dual-quad Xeons with multiple GPGPUs (general-purpose graphics processing units). The video-game consoles consumed 90% less energy than any alternative.

@barneymcg999 @Rainmaker1973 No. Believe me, bitcoin mining is such a problem on big machines with a lot of users that there are a *lot* of safeguards and you get in a *lot* of trouble if the admins catch you doing that.
English
@djeucharist @Rainmaker1973 No. They're not used for operational purposes. They're used for analyzing data.
English
@Rainmaker1973 I'm impressed! The whole American Department of Defense is running on a cluster of Playstations!

@PrairieIT_Neal @Rainmaker1973 Power density is probably low enough that it's not a problem.

@Rainmaker1973 The PS3s are on bakers racks instead of traditional server racks. Heat wasn’t an issue?
English
@MrEXEfiles @Rainmaker1973 Key issues include
Small and non-expandable RAM.
slow networking compared to real HPC network
Storage is similar, I expect. And with Sony, even with Linux on it, you're always dealing with proprietary stuff with interfaces that are locked down, so you can't optimize them.
English
@Rainmaker1973 I wonder what the downside to using PS3's is compared to a conventional supercomputer.

@ThingOldest @Rainmaker1973 I think this is the device that was basically an early arithmetic logic unit. It's not a general-purpose computer, but a very large subset of one. It was a fundamental building block of the first real computers (and was likely partially copied for...Eniac, I think?)
English
@Rainmaker1973 Cool! This is the oldest digital computer…
TheOldestThing@ThingOldest
The oldest known electronic digital computer is the Atanasoff-Berry Computer (ABC), designed and built by physicist John Atanasoff and his graduate student, Clifford Berry, at Iowa State College (now Iowa State University) in the late 1930s and early 1940s. The ABC was not a general-purpose computer but was specifically designed to solve systems of simultaneous linear equations, a common problem in physics and engineering. Completed in 1942, the Atanasoff-Berry Computer used binary representation for data and electronic switches (vacuum tubes) for computation. While it didn't gain widespread recognition during its time, the ABC is considered a pioneering work in the development of electronic digital computers. The ABC's priority is debated among historians of computer technology, because it was neither programmable, or Turing-complete. In 1942, WWII raged across the globe with the Battle of Midway occurring in June and the Manhattan Project officially beginning.

@emilydoesastro Congratulations, Doctor! Welcome to the club.

I passed my thesis defence! I have a PhD now!*
SO relieved, the defence went really smoothly and I didn't really feel nervous. Was mostly just excited to finish! Is such a good feeling =)

@MIRA_OBS @RadPlanets Yeah. Pretty much what you're looking for is "~".

@RadPlanets Technically ~ is similar to, ≈ is approximately equal to.

@WhySharksMatter See: the size of the apartments in Friends and any other show set in NYC. See: the sizes of the insides of any vehicle (except airliners) in any movie ever pre-go-pro.
