zerd··on Twitter now requires an account to view tweets
Well they killed the API, what did they think would happen? It's easier to control access and rate limit with a proper API.
zerd··on The rule says, “No vehicles in the park”
Are you saying that an ambulance is not a vehicle?
zerd··on Hacking my “smart” toothbrush
This is probably why they're doing all the electronic shenanigans, so they can later verify that you're using a Genuine Authentic® brush head.

zerd··on Kafka vs. Redpanda performance – do the claims add up?
Zookeeper absolutely does fsync, you can't disable it (without libeatmydata). It will log a warning if fsync is too slow as well.
zerd··on Google Cloud Europe service disruption
I got errors trying to open the instance group list and we don't have any resources in europe-west9.

But then you need some kind of load balancer, which hsn915 said was "too complicated".
zerd··on My Hardest Bug Ever (2013)
And this is why ECC is a good thing.
zerd··on COBOL: Thinking about it wrong
I only have minor experience with COBOL, but in my mind the issue is that those 800 million lines of code don't have a single unit test, because testing COBOL is really hard. Which makes it dangerous to do any refactoring.

Specifically the snippets I've seen do some in-line SQL to get its data, some business logic and then updates. The logic is rarely in a procedure that takes parameters, because that doubles the number of lines of code you need. So the only way to test it is to bring up a database, insert some test data, assert and clean up the database again. Which is a lot harder since "insert some test data" gets complicated because of different constraints and triggers etc. Then running it regularly is harder than it should, there's no SQLite equivalent database so you typically need to run it on a mainframe etc.

I've worked on replacing a piece of functionality from COBOL to Java, and I was working from the business requirements that was basically a large spreadsheet of conditions and results. E.g. if age > 67 and not retired but have more than 3 kids, etc then this value. The code I wrote was gnarly because of all the combinations of different conditions, nested ifs 3-4 layers etc. And then there was ambiguity if multiple conditions hit, which one took precedence. I asked if I could look at the equivalent COBOL and the actual logic was about 10 lines long (not including headers, comments etc). Wish I had seen that before I started coding. It was quite readable and well commented too. So the actual language isn't _bad_, but the lack of tooling around it is severely lacking.

LTT also tested this for FPS games and both professionals and casual gamers improved significantly going from 60HZ to 144+. https://www.youtube.com/watch?v=OX31kZbAXsA

Cmd+Shift+T is fine to hold to re-open a tab, but Ctrl+Shift+T makes my hands hurt on a regular keyboard. It's also annoying to have to switch between Ctrl+C to copy in normal apps, but in a terminal that would cancel the command, so you have to do Ctrl+Shift+C there. On a mac keyboard it's always the same. I've tried to use e.g. autohotkey to get the same consistency but it's rather annoying (need to inspect which window is active, sometimes doesn't work).

zerd··on QCAD – Open Source CAD System
Warning: loud music
zerd··on Almost all searches on my independent search engine are now from SEO spam bots
Also, I've noticed that the list of products reviewed is limited to only those that _have_ Amazon affiliate links. If a product is only available on not-Amazon stores, they don't even get mentioned. Which is a bias in itself.
zerd··on Wireless is a trap (2020)
Maybe because you just talk, or just listen. Having a conversation where you go back and forth is when it's the worst, especially with multiple people.
zerd··on What Flips Your Bit: Cosmic Ray Errors at Mozilla
Bryan Cantrill mentions in this talk that they saw no correctable errors, until they suddenly got uncorrectable errors. Turns out that the firmware was hiding the fact that it had been correcting ECC errors the whole time. https://youtu.be/vvZA9n3e5pc?t=1193
zerd··on Podman can transfer container images without a registry
I hope the image registry abstraction opens up the possibility to improve the storage and transfer of images without breaking backwards compatibility. See https://www.cyphar.com/blog/post/20190121-ociv2-images-i-tar for why tar is not optimal.
zerd··on Apple M1 Ultra
From the tweet reply you used sccache with hot cache, which would probably be mostly single-threaded since it's just fetching and copying things from cache.

HP Microserver Gen8 with iLO from 2014 also had generated admin password.

In this video [1] he mentions that each 100mp image is around 600MB, which aligns with the size of the 4-shot multi-shot mode of the H6D-400C MS. 8439 photos 579MB would be around 4.7TB in raw format.

The cost of the camera is a small drop in the bucket versus the rig and work gone into this.
zerd··on Ask HN: Has Google search become quantitatively worse?
Google now also has an extreme recency bias. Most things I search for will give top results for recent SEO optimized blog posts/Youtube videos instead of established authoritative resources. If you search for something that happens to overlap with a recent movie name, good luck, it'll drown. And I constantly "have" "to" "search" "like" "this" because Google thinks it knows better than me.
