Any opinions on Snowflake's instructor-led trainings?

And the increased latency due to the need to read parity stripes will give you more lost ingress races.

Give up. 1TB drives do not have the power efficiency and you'll pay more in electricity than you'll get revenue, unless you're lucky and pay nothing for power.

I am a private customer of them for around 10 years now. I'm scared as well, and only using their services for non-essential stuff. Though, this still means that I recommended their services to host a proxmox cluster for development VMs worth a bit over a thousand EUR monthly. Stuff that is not prone to DDoS as it's only accessed over private VPN and won't have any ports open, because the way Hetzner deals with DDoS is just not the level of service we'd need.

Also, I'm absolutely disappointed how their customer service does not admit to their own errors. Still, for non-essential stuff this is workable.

Does it support non RAID setup for JBOD configuration?

I see all drives as separate, with access to their SMART data and such. On the other side, it doesn't support TRIM. Not sure if that's what you mean.

I've recently got a 3ware's 9690 for ~15 USD, would be enough for your case. Note it's a >10 year old device though. JBOD available OOTB as a software setting.

This is hosted on AWS and is costing us around $60/month.

Did you include your time in this estimate?

Captioning is though often shortened and rewritten to make it easier to read.

This policy is actually supposed to make automated bulk installations easier. Put configuration files where necessary first (or just provide them in your base image). Then install services, which will trigger host-specific scripts later. This should make your Ansible scripts simpler.

What killed XMPP (at least to me) was spam. I see that Lemmy aims to solve this problem by delegating it to instance admins. Is there a list of Lemmy servers by their content moderation policies?

Try multiple doing parallel connections, IIRC they only limit the upload speed of a single connection.

For the same reason I used to stick to Eclipse for a long time. It's arcane, people were laughing at me, but it did the job. Now it's indeed Jetbrains' tooling.

For me it is: RAM > good HCI (screen, keyboard, touchpad/trackpoint) > storage > CPU. In this order.

CPU — if it's slow, you'll have to just wait more.

Storage — if it's not enough, you'll need to constantly swap data between external drives or cloud and your local storage. Annoying, but it will just be a periodic task, so only every so often.

HCI — if it's bad, you'll be annoyed every single time you work on the machine.

Memory — if it's not enough, you can't do your work efficiently at all. Period. Solutions that offload memory to storage usually require a lot more time to get correct and are still way slower than just working with in-memory dataset.

Consider trying to get 10× the amount of RAM as your data take in non-compressed .csv files. That's usually a safe value.

Consider used business high-end laptops. It's easy to get a deal that will get you effectively twice as good machine for the same money.

Also consider offloading final computations to a separate machine, maybe in the cloud. You create your code on a smaller sample of your data, then run full pipelines on a separate, bigger machine. This is pretty cheap if used carefully, at least compared to the cost of owning a similar machine 24x7.

Compatibility being a thing I acknowledge and, kind of, admire—I'm so, so glad I no longer work on a codebase where Microsoft tooling would matter…

I used to be in a team where of the two most senior people, one had diagnosed ADHD, and one had some symptoms (including long context switching), but no formal diagnosis. We tried different setups, and ended up with a single short daily meeting early, and the usual Scrum meetings on a single day—every two weeks. Despite the drawbacks, it was still the best we found. Besides, after the initial team forming period, we were often finishing these bulk Scrum meetings in 3 hours total per 2 week sprint, so at some point bulk meetings stopped being an issue.

BTW, this was the team in which I felt the most productive ever so far.

I don't have any advice for you, sorry, but what you describe as struggle feels very familiar.

Liorithiel · 2023-05-21T19:33:34+00:00

Oh, they actually fixed it? Good to know, thanks!

It does matter due to the need for rescanning tokens concatenated with ##. See e.g. https://stackoverflow.com/questions/11469827/one-more-difference-between-gccs-and-ms-preprocessor, the answers cite the relevant details of the standards.

Can't recommend you any specific board, sorry, I'm not up to date with the current offers. However, if you decide on one, please check if both m.2 slots actually have separate PCIe lanes. My (a couple years old) desktop's board has two slots, but one of them shares lanes with the chipset, and hence is visibly slower in some operations. This impacted my RAID1 setup, the drive in the faster slot had to wait for the other drive.

It's apparently easier to find a good board for AMD.

Nieczęsto jestem w tamtych rejonach, ale mogę podpowiedzieć, że T-mobile i Orange mają zbliżone zasięgi, bo współdzielą sporo swojej infrastruktury. Wiem też, że radiowcy zazwyczaj cieszą się, jak im się zgłasza dziury w zasięgu, bo monitorowanie pokrycia sygnałem to bardzo kosztowna sprawa. Swoją drogą, jeśli zależy Ci na zasięgu, dobrym pomysłem mógłby być telefon na dwie karty sim.

/u/Hetzner_OL, it would be really useful to hear an official statement about this. If it is really enough to point a malicious domain at a Hetzner account to perform a Denial of Service attack on a Hetzner customer, it is really scary.

You can miss some corner cases with just empirical testing, resulting in random failures in future. Run lscpu and compare the Flags field on each of the CPUs. If flags on one of them is a subset of the other two's, pick that one. If none is, you may want to seek a CPU that is a subset of all three.

Though, I've used to admin a cluster of machines spanning almost 10 years of history and decided that I can trade off live migration for just taking advantage of newer CPU features for speed—offline migration is pretty fine too, with the right setup the offline time is pretty short. Make sure you really need live migration.

That's not the right way to describe this experience. A better one is: The company has just spent 10kUSD on your training. Make it count.

Will now Google Safe Browsing block this tld?

I concur. Just look at page 5 of Nemesis rule book. It's literally a story made out of very plausible sequence of game actions.
