As far as I can tell we are in violent agreement. When you do complicated things you have to tune, when you don't you don't.

Sure, a few examples that happen with modern JVMs (even 25). Essentially anything addressing a large amount of memory (think > 100gb). This can be databases, streaming solutions and so on, where you start tuning the GC just to have a smo

Perhaps you work on simple CRUD applications? In my experience the 90/10 are reversed.

I know a company already operating like this in the fintech space. I foresee a front page headline about their demise in their future.

The only reliable way to get things fixed with these large companies, is to have a direct point of contact to them. I have one. You can find my email in my profile, ping me and I will try to get a human in the loop for you.

I once sent this as a reference to a government agency I was consulting, to illustrate to them, how they operated.

It reminds me quite a bit of collision engines for 2D physics/games. Could probably find some additional clever optimisations for the lookup/overlap (better than kd-trees) if you dive into those. Not that it matters too much. Very

There used to be a joint online project to compute these tables in a SETI like distributed system. Everyone who contributed their CPU cycles, could use the tables. And yeah, around 2005-2008.

The latency and bandwidth really isn't there for HPC.

Sure, so the use case I have requires elastic storage and elastic compute. So CephFS really isn't a good fit in the cloud environment for that case. It would get prohibitively expensive.

I've had to test out various networked filesystems this year for a few use cases (satellite/geo) on a multi petabyte scale. Some of my thoughts: * JuiceFS - Works well, for high performance it has limited use cases where privacy c

So the argument is essentially "8 billion people dying is a problem, that is worse than whatever the result of longevity is". I'm not sure that it is.

It seems to ping-pong back and forth. Our monitoring is basically spamming us with DNS down, DNS up every 5 minutes or so.

Agreed, let's upvote this thread higher to get some eyes on this.

No idea. Never actually seen a failure like this in practise.

Whois isn't even showing the domains and name servers. Not to mention DNS records. Its like the domains don't exist anymore.

While I do love Postgres and use it daily on AWS and Google Cloud, I will add that the managed Postgres on Google Cloud is a mess in some areas. For example they use some EOL extensions outdated for 10+ years (a specific example is GEOS) an

I might just take you up on that.

by eerikkivistik 2y ago
Thanks for clearing that up. Few followup questions: You don't actually directly charge for storage itself, so I assume this a "bring your own s3 bucket" type of deal, correct? How long does data, that is no longer being acce

Can you elaborate on a few things with regards to your pricing: * What does "$0.05 / gigabyte transferred" mean exactly. Transferred outside of AWS or accessed as in read and written data? * "$0.20/GiB-mo of high-sp

FlexFS kicks ass. I benchmarked it for our data storage and processing layers in value.space (satellite data processing and analysis) and we will most likely migrate to FlexFS in the near future. Out of curiosity, why did you choose EFS, it

Not sure. Perhaps a further investigation by the authorities will reveal the reason.

You absolutely can and it is true.

That is the goal.

So this is done via InSAR ( https://en.wikipedia.org/wiki/Interferometric_synthetic-aper... ), leveraging ESA satellite data. Not sure on the buzzword bingo there.

It is an after the fact survey done on historical satellite data. More data can be found here: https://newsletter.value.space/p/bridge-collapse-germany-aty...

I was gonna say... When your system is large enough to run into this specific performance bottleneck, pop a bottle and celebrate, you are making enough money to solve that problem. While knowing this information is useful, most services fai
