mrgaro··on The C++ standard for the F-35 Fighter Jet [video]
There are missiles in which the allocation rate is calculated per second and then the hardware just has enough memory for the entire duration of the missile's flight plus a bit more. Garbage collection is then done by exploding the missile on the target ;)
mrgaro··on GrapheneOS is the only Android OS providing full security patches
It's not really an option. Beside various communication tools, many many banks require you to have a smartphone as their 2FA option.
mrgaro··on BMW PHEV: Safety fuse replacement is extremely expensive
This only applies to pre-2020 Tesla's and it was around 8-10 years. The more recent ones are designed to last the vehicles lifetime.
mrgaro··on Comparing AWS Lambda ARM64 vs. x86_64 Performance Across Runtimes in Late 2025
I tried to do a very low latency https endpoint with Lambda and Rust and wasn't able to get less than 30ms, no matter what I tried.

Then I deoloyed an ECS task with ALB and got something like <5ms.

Has anybody gotten sub-10ms latencies with Lambda Https functions?

mrgaro··on Efficient solar cooking that stores heat in sand
At least in Nordics (I'm from Finland) heat pumps are rapidly replacing other forms of heating. One can get a big enough heat pump for a 200m^2 house (including heating hot water) for around 10-15k, with a few thousand more for installation price.

Adding 10-15kWp of solar panels to the roof is around 6k more. It's definitively a no-brainer as it will recoup the investment in 5-10 years.

mrgaro··on A file format uncracked for 20 years
It helps tremendously if you have a programming background as usually the developers behind the original format didn't have any need to make things harder than they need to be. Because of this, you can often guess how the format works, aka. "If I was the original developer, how would I do this?"
mrgaro··on I Am Mark Zuckerberg
I used to have a very common name (before getting married and took my wife's last name). Imagine that I have firstname.lastname@gmail and somebody was genius to take firstname.lastnam@gmail.

I felt this was so stupid, that i quickly lost any willingness to try to relay the emails to their original owner, as the other person had zero interest to change their address to be harder to mistype.

mrgaro··on Why is Zig so cool?
Doesn't Golang support this as well, out of the box?
mrgaro··on A visualization of the RGB space covered by named colors
I'm curious to understand the need to have names for such many different colors and I'd love to hear your take! A naive reasoning would say that names are useful if at least two different persons know the meaning for a name and thus it will help communication.

Now I'm not sure how many colors are there in that list, but it feels like there are too many to be practically useful. How do you see this?

mrgaro··on Affinity Studio now free
Highly recommend DaVinci Resolve, way better than Premiere in my opinion.
mrgaro··on Jeep pushed software update that bricked all 2024 Wrangler 4xe models
Would you? I think that EU mandates a mobile connect for emergency services (eCall), but can you point out a legislation which forbits the owner to disable it in the vehicle they own?
mrgaro··on YAML document from hell (2023)
HCL is so annoying as it tries so much to prevent user to "do too complex things" and thus it doesn't have proper iterators other similar concepts, which would be very useful when defining infrastructure as xode.

This has resulted bunch of hacks (such as the count directive on terraform) so that the end result is a frustrating mess.

mrgaro··on SSL certificate requirements are becoming obnoxious
What dictates that certificate update needs to have a manual change process? I'd bet that it's just legal team saying that "this is how it's always been" instead of adjusting their interpretation as the environment around changes.
mrgaro··on Standard Thermal: Energy Storage 500x Cheaper Than Batteries
Good point and very true!
mrgaro··on Standard Thermal: Energy Storage 500x Cheaper Than Batteries
10ft is definitely not enough for practical use. In order to heat a rural house with a heatpump connected to geothermal you need in order of 200-300ft deep hole, at least here in Finland.
mrgaro··on Custom telescope mount using harmonic drives and ESP32
I'm most impressed with being able to order the CNC'ed metal parts. I'm just a novice cad designer and I'd love to learn that capability.
mrgaro··on Show HN: Whispering – Open-source, local-first dictation you can trust
I'd love to find a tool which could recognise a few different speakers so that I could automatically dictate 1:1 sessions. In addition, I definitively would want to feed that to an LLM to cleanup the notes (to remove all "umm" and similar nonsense) and to do context aware spell checking.

The LLM part should be very much doable, but I'm not sure if speaker recognition exists in a sufficiently working state?

mrgaro··on Apple bans entire dev account, no reason given
How it is possible that your bank don't have an Android app if they have an iPhone app?
mrgaro··on What 'Project Hail Mary' teaches us about the PlanetScale vs. Neon debate
Depends a lot what you are after, but look for writers like Dan Simmons, Arthur C Clark or Alastair Reynolds.
mrgaro··on People are bad at reporting what they eat. That's a problem for dietary research
Thanks for you quick answer. I want to clarify that I would have liked to try the app for a few days before activating subscription.

Now with the current flow I would need to activate the subscription and then immediately go to Play Store settings to deactivate the subscription so that I would not forget it.

mrgaro··on People are bad at reporting what they eat. That's a problem for dietary research
I downloaded SnapCalorie to try it out on Android. I went all the way through the sign-up phase, only to discovery that I would need to activate subscription in order to have the 7-day trial. Ended up uninstalling the app :(
mrgaro··on Making glow-in-the-dark Strontium Aluminate
Not sure what the modern one are, but they will still glow in the morning hours. They are very very handy!
mrgaro··on Diagnosing an Unusual WiFi Issue (2020)
As Qt is a GUI library (among other things) I would guess that Paint Pro is written entirely using Qt.
mrgaro··on Exploring LoRA – Part 1: The Idea Behind Parameter Efficient Fine-Tuning
Actually it does: Lora the radio protocol has parameters to tune. Usually both sender and receiver needs to match these, so I read this like a method how these could be automatically tuned based on the distance and radio environment.
mrgaro··on ChatGPT Pro
OpenAi enterprise plan especially says that they do not train their models with your data. It's in the contract agreement and it's also visible on the bottom of every chatgpt prompt window.
mrgaro··on Hetzner cuts traffic on US VPSs, raises prices
EU transit costs and peering agreements are much more relaxed and cheaper than in US
mrgaro··on OpenZFS deduplication is good now and you shouldn't use it
For text based logs I'm almost entirely sure that just using compression is more than enough. ZFS supports compression natively on block level and it's almost always turned on. Trying to use dedup alongside of compression for syslog most likely will not yield any benefits.
mrgaro··on FTC announces "click-to-cancel" rule making it easier to cancel subscriptions
It does work, because the companies will realize that gmail no longer delivers their emails and that they need to change their behavior. Also for example AWS SES (Simple Email Service) will give you clear warnings if it detects that recipients mark their email as spam (it seems that for example gmail delivers this information somehow to SES).
mrgaro··on How I learned to stop worrying and love userspace networking
I'd say the opposite instead: we need Kubernetes distributions, just like Linux needs distributions. Nobody wants to build their kernel from scratch and to hand pick various user space programs.

Same for Kubernetes: Distributions which pack everything you need in an opinionated way, so that it's easy to use. Now it's kinda build-your-own-kubernetes at every platform: kubeadm, EKS etc all require you to install various add-on components before you have a fully suitable cluster.

mrgaro··on Air Con: $1697 for an on/off switch
Gree HVAC units have built-in wifi which supports fully local remote control and there are OSS packages (including home-assistant).
