Because a lot of people enjoy the process. Why do you think people so wood working as hobby or the whole demo scene?

hanikesnon We replaced Redis with MySQL for inventory reservations and it scaled

You'll quickly realize PCI mainly applies to the credit card industry and not to something like Europe's psd2 and sepa instant.

hanikesnon Shopify replaced Redis with MySQL for inventory reservations–and it scaled

Most payment methods in the world don't support separate authorization and capture.

hanikesnon I built a vulnerable app and spent $1,500 seeing if LLMs could hack it

What's bad about it and what's a better one?

How is this related to kubernetes?

hanikesnon BuildKit: Docker's Hidden Gem That Can Build Almost Anything

Why would you use the horrible GHA cache and not a much more efficient registry based cache?

hanikesnon Phoenix: A modern X server written from scratch in Zig

It does on Android

hanikesnon A $1k AWS mistake

Yep and have to pay for public IPs, which can become quite costly on it's own. Can't wait for v6 to be here.

hanikesnon Android developer verification: Early access starts

>instead require the user to manually go into settings to turn them on, but if they do then it's still possible

They clearly addressed this option in the post, under sufficient social engineering pressure these settings will easily be circumvented. You'd need at least a 24h timeout or similar to mitigate the social pressure.

hanikesnon Bluetooth 6.2 – more responsive, improves security, USB comms, and testing

This can already be done with LE audio, support is coming slowly.

hanikesnon Asahi Linux Still Working on Apple M3 Support, M1n1 Bootloader Going Rust

>this project appears to be on life support

Why do you think that? The upstreaming efforts are more fruitful than ever.

hanikesnon Asahi Linux Still Working on Apple M3 Support, M1n1 Bootloader Going Rust

>I'm not really sure what to do. Maybe this MacBook Pro was just a one-off, and I have to go back to buying Windows laptops and putting Linux on them. But they just aren't as nice.

Why would you think that? They're working hard on upstreaming all patches ATM, adding new hardware support will be much easier afterwards.

hanikesnon TP-Link conducts Wi-Fi 8 trials, promises better reliability and lower latency

In my experience Apple clients have been incredibly clingy to 6ghz bands, while much better 5ghz was available.

hanikesnon Flightcontrol: A PaaS that deploys to your AWS account

>Terraform is there specifically to solve the Aws infrastructure complexity

No, terraform passes AWS complexity 1:! onto you, it just allows you to tackle it in an ordered fashion.

hanikesnon Building the heap: racking 30 petabytes of hard drives for pretraining

Why 5h a week? Just for hardware?

hanikesnon Intelligent Kubernetes Load Balancing at Databricks

I've been using a standardized xds resolver[1]. The benefit here is that you don't have to patch grpc clients.

hanikesnon Tesla Faces US Auto Safety Investigation over Door Handles

That's the correct entry in the manual: https://www.tesla.com/ownersmanual/model3/en_us/GUID-A7A60DC...

hanikesnon Automating Distro Updates in CI

Renovatebot would solve this consistently and is more broadly applicable.

hanikesnon Dissecting the Apple M1 GPU, the end

>The M3+ GPU is also very different.

Any sources for that? I'd be quite surprised if Apple had radically altered the architecture.

hanikesnon Build durable workflows with Postgres

First: It's great to have some serious competition in the durable execution market! You build some impressive tech already! It took me a decent time to investigate before pulling the trigger on temporal at my current PSP fintech as you'll end up with a pretty hard vendor lock-in which has to be worth it.

I have to say the architecture blog post is very leightweight on details, which makes it hard to judge so you have to dive into the docs for the spicy details and I see abig showstoppers for our usecase:

1. Workflow versioning: It seems currently impossible to properly upgrade inflight workflow without manually forking the workflow

Also the marketing material and docs aretoo handwavy on the idempotency and determinism constraints, which makes them dbos seem to good to be true. I'd also love to see higher level abstractions around message sending. Temporal's signal, query and update are essential building blocks for our use cases and allow some quite interesting use cases as you can really view workflows as actors.

I hope you can keep innovating as temporal really is too heavy for a lot of use-cases.

hanikesnon Rethinking PostgreSQL Storage

Yeah storage appliances predate public clouds fo at least a decade. Not even talking about mainframes etc.

hanikesnon The cryptography behind passkeys

It works well enough. When you need to signup for a new service on the go, you can add your backup key when you get to it. Having the backup key in a safety deposit box hardly accessible seems like a non-goal given you protect it with a pin with a very limited number of retries.

hanikesnon The cryptography behind passkeys

It works great with physical keys. Just need one as backup you leave at home.

hanikesnon Zoom outage caused by accidental 'shutting down' of the zoom.us domain

It's usually cached

hanikesnon Why Companies Don't Fix Bugs

hanikesnon The cost of Go's panic and recover

How often did you access a nil pointer and caused a panic?

hanikesnon Apple's Software Quality Crisis

Linux seems like the opposite to me a slow marathon to achieve perfection. With pipewire, systemd and wayland there's less cruft than ever and you get the best out-of-the-box experience since it's inception.
