You're getting ripped off. NVMe SSDs are expensive, but not THAT expensive. A 4Tb drive should be around $1k even with some "enterprise" markup.

Given the cost of 24 of them, you can probably buy solid silver heatsinks watercooled with tears of sysadmins.

Oh, I never disagreed about the state of DNSSEC. It's horrible. Along with the rest of the DNS infrastructure (I just had the reason to remember the DNS haiku again today, unrelated to .de). My disagreement is that I believe that DNSSE

by cyberax 6mo ago
Sure. But that was not the issue with .de, it has about the same level of DNSSEC adoption as .com DENIC screwed up the TLD itself, and .com/.net are just as susceptible.

I can see the periodic rotations used as a way to keep up the operational experience. This is indeed a valid reason, although it needs to be weighted against the increased risk of compromise due to the rotation procedure itself. I'm ju

You're wrong. Both .com and .net are signed (`dig RRSIG com.`), and if they screw up, then all the com/net zones will become inaccessible.

> Keeping key material secure for more than a decade while it's in active use is vastly more complex than keeping it secure for a month, until it rotates. Nope. Key material rotation is just circus when it's done for the sake o

I'm playing with LORA/Meshcore right now (I have an nRF52840 lying around). I'm pretty sure I know how to do that, will take a look.

Not really? .com and .net are still up If Let's Encrypt goes down, half of the Internet will become inaccessible in a week.

Podman in general is much higher quality than Docker. For the last 5 years, Docker was throwing all kinds of stuff against the wall to see what sticks, neglecting foundational issues. Moreover, podman-compose integrates really easily with s

FWIW, most of these issues were recently fixed in podman-compose. I can now use the current git version of podman-compose interchangeably with docker-compose. And one nice thing about podman-compose is that it's ONE PYTHON FILE. You ca

Their resulting density (~450 square meters per housing unit) is only a bit more than a dense SFH zone. And they also are able to tap into an aquifer, significantly improving their capacity. In general, you absolutely can do district-level

Just use Podman. Docker's development is driven by managers who want to shove hosted services everywhere. Meanwhile, the basic stuff like caching doesn't work properly.

It doesn't work this way. Dense cities just don't have enough space for geothermal heating. It really works for single-family homes only, or maybe just a slightly more dense areas. Not to mention that city infrastructure is WAY to

Yeah. I'm just saying how it could have been overlooked. Doesn't excuse it, though.

This type of damage is common if you look at the spot that the laser makes on an object. Your eye automatically focuses it into the foveal area. I don't remember ever doing that without protective glasses, but evidently I did at some p

With high-powered lasers, you can go blind instantly. I also worked with lasers (in a lab, with all the safety precautions), yet I have slight eye damage in one eye. There's a small burnt patch on my fovea, so if I look at something li

Sorry, it's on the entirely wrong side of the spectrum. We're doing geospatial analysis. Although it'd be hilarious to see what it thinks about X-Rays.

The general AI models are useless if you need precision. They are designed to create/analyze pretty pictures. But specialized models can be inhumanly good. I know, our main product is a model that does _precise_ analysis :)

In general, experimenting at home with these kinds of light intensities is NOT a good idea. Way too much risk of accidental eye damage.

It's hard to design tests for CS. Leetcode is too simplistic, it just tests the basic algorithmic knowledge that is nearly useless for regular software development.
