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!

@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!)

@drskyskull I know, right??!? 34-0, clean sweep!

[Craig Steffen (him/his) @gevmage]

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

Thank you @codergirl1991 for writing this helpful article.

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

@Renard93801084 @Rainmaker1973 There were clusters of Sony consoles used for general-purpose computing, yes. Some of them may have been useful.

[Craig Steffen (him/his) @gevmage]

@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.

[Craig Steffen (him/his) @gevmage]

@djeucharist @Rainmaker1973 No. They're not used for operational purposes. They're used for analyzing data.

[Craig Steffen (him/his) @gevmage]

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

[Craig Steffen (him/his) @gevmage]

@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.

[Craig Steffen (him/his) @gevmage]

@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?)

@emilydoesastro Congratulations, Doctor! Welcome to the club.

[Craig Steffen (him/his) @gevmage]

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

@astrotoya Oh my gosh! Cuuuuuute!
