zerd··on FCC launches inquiry to increase minimum broadband speed [pdf]
If I take a video on my phone and sync it to the cloud that's easily more than that. And if that takes up the whole 10 Mbit, video calls get unusable.
zerd··on Log is the "Pro" in iPhone 15 Pro
I was trying to take a passport photo, and one of the requirements is "has not been touched up". But when I took the photo with my phone, I noticed that it had been very helpful in touching up my face by removing almost all of my wrinkles and made my skin nice and soft. Even with all "enhancements" off. This was on an Samsung S10, I tried with an iPhone SE, it was slightly less visibly touched up, so I used that, but still definitely had a "beauty" filter built in. It's probably implemented in ASIC so you basically can't turn it fully off.
zerd··on Shrinkflation Tracker
I've been buying the exact same pair of boxers for years. This year I noticed that they were actually smaller, by almost an inch. Elastic band is smaller and the actual length, so it started chafing. Shrinkflation even on clothes.
zerd··on WiFi can read through walls
The page, paper and video say that as well. The difference here is that this is tracing still objects.
zerd··on A surprisingly simple way to foil car thieves
A friend had a car that required that you hold a magnet at a very specific spot in the back of the arm rest to be able to start ignition. Don't think he ever tried to valet that.
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.

Are you saying that an ambulance is not a vehicle?

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.

zerd··on Play Counter Strike 1.6, with full multiplayer, in the browser
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).

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.

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.
