andruby··on ‘You Are Done’: The letter sent to King by the F.B.I (2014)
not just audio unfortunately.
andruby··on Raspberry Pi Zero 3W and Pi 4 Model A spotted in device trees
Yes I know, and agreed. <€3.0 is still cheap enough to buy a dozen and keep in a drawer for a bunch of applications
andruby··on Raspberry Pi Zero 3W and Pi 4 Model A spotted in device trees
Not exactly £1.5, but you can get them just under €3.0 shipped (with duty etc) to EU when ordering a bundle of 10 on Ali.

In November last year I could still buy them for €1.57 each.

andruby··on New 14‑inch MacBook Pro with M6
What would have been the right amount of harping about the environment though? Or is it always going to be a pointless exercise trying to convince/alert people?

Or is the only way to do that successfully, doing it subconsciously/covertly like the state actors are swaying public opinion? :-/

andruby··on New 14‑inch MacBook Pro with M6
1/ You're on HN, the audience isn't "everyday average people"

2/ This is like complaining that climate activists were harping too much 30 years ago, and that's why nobody listened

andruby··on Microsoft offers mass buyouts for roughly a quarter of its workforce
This feels like a failure in (late stage) capitalism more than corporates.

I would love if we'd put efforts towards better economic/political systems.

andruby··on DeepSeek just open-sourced its inference engine
These datacenters run the GPU's close to 100% usage 24/7. The Mac mini at home probably has <25% utilization. And then there's economies of scale, wholesale discounts, etc.

The Mac mini GPU also isn't as optimized as the datacenter GPUs

andruby··on Grieving the loss of details
People want recognition when doing something hard that took time, effort and dedication.

Training a year, and running a marathon feels more worthy of recognition than driving 42km in a car from the start to the finish.

While I don't empathize with the defeatist tone of the post. I do empathize with this part.

andruby··on Beauty in DVD Menus
It might have been discovered by people ripping the dvd. iirc the rip software detected the chapters
andruby··on Beauty in DVD Menus
I loved the interactive DVD menu's. The deleted scenes and director commentaries or alternate endings were such a bonus. I miss those
andruby··on Sharing AI progress in mathematics
I fully agree that we should have incentives and systems in place that the government works for the people.

> government should be small enough that it fears the people

How would that work when the government controls the military? Would that mean that a country's military has to remain small?

andruby··on Sharing AI progress in mathematics
I used to, but not anymore. The incentives and human behavior seem to lead to corruption. New tools have made it too easy to pervert real/honest democracy into "pseudo" democracy/idiocracy.

A well-funded minority can shape what the majority is angry about.

andruby··on Best-selling Zigbee temperature sensors tested and compared
would the difference between those two show up in the measurements that the article made?
andruby··on Shipping JPEG XL in Chrome
> nobody benifits from supporting it

Do you mean the users of the browsers not benefitting, or specific Google employees/stakeholders?

andruby··on JetBrains reports revenue growth, net financial loss for 2025
I don't know the details of Czech accounting, but large investments are usually amortized over several years. It impacts cash-flow more than profit
andruby··on Testing 12 different Zigbee temperature/humidity sensors
I think buyers care more about accuracy and resolution than which sensor. If it’s accurate, with hugh resolution and has good battery life, do you care if it’s Bosch or A Chinese name you’ve not encountered before?
andruby··on The Escalation of War in Ethiopia
Civilizations flourish and falter. Mesopotamia, Babylonia, Egyptians, Romans, …

Given (enough) time, it’ll also happen to the ones at the peak now.

andruby··on NASA asked several former SR-71A staffers to help secret restart
Even in that case, cheap and unmanned would be much more cost efficient.

The SR-71 was uncontested in the 70'ies, but it wouldn't be today. Today it would be vulnerable. Missiles reach higher and fly faster. There are missiles that are designed to intercept ICBM's, which come in faster than a Mach-3 SR-71.

Radar detection, tracking and firing has also become much more effective in the last 60 years.

andruby··on NASA asked several former SR-71A staffers to help secret restart
Do you have a source on these being suicide missions without enough fuel to get back? The F-14 has drop tanks, and after firing all missiles, that sheds another 4,000+ lb of payload.

I think they planned with proper return. Which can also be at slower speed.

andruby··on Backblaze drive stats for Q2 2026
My NVMe died a month ago (failed self-test in bios). Was 4.5 years old. Western Digital had a 5 year warranty. SanDisk owns them now and honored the warranty. The replacement NVMe is on the way.

How old is your NVMe?

andruby··on The last time my family was replaced by technology
Looking at the news in the US, it feels like the wealthy and powerful are working that problem.
andruby··on Google’s Project Suncatcher to put ML infrastructure in space
> The 220C is the temperature at the hot end of the heat pump. The chips are on the cold end of the heat pump.

If we want the heat pump's cold end at about 40–65°C, then for each 1MW of GPU heat, we need another 1MW of heat pump power. Now you need 2MW of solar power.

Good news is that the radiator at 227C (500K) can emit about 5× more heat per square meter than at 57C (330K)

andruby··on Rails World 2026 Opening Keynote [video]
I think most people on HN know robby russel. Have you ever used ohmyzsh?
andruby··on Apple has added persistent 'ads' to iOS, and it's driving users crazy
The irony of this website being so loaded with ads that I can barely read the contents is palpable :P

But on-topic: iOS shouldn't show any ads.

andruby··on I said no and Apple said yes
My home setup has both a trackpad and mouse (and a separate keyboard). I like them both. In practice I use 65% mouse and 35% trackpad I think. Trackpad is great for horizontal (or 2d) scrolling and gestures. Mouse has better ergonomics for accurate pointing, and is more natural in some apps (eg KiCAD).
andruby··on I said no and Apple said yes
For people making a living on western software engineering salaries, why wouldn't (Apple) hardware be worth the price?

A lot of other crafts and jobs need way more expensive hardware. Software engineers "only" need a $1,000 - $3,000 laptop every 5 or so years. That's typically less than 0.5% of that 5 year's salary.

andruby··on MiMo v2.6
> China has recently awarded 1.3 to 1.4 million engineering bachelor's degrees a year, and about 292,000 postgraduate engineering degrees in 2022. [0]

> For the US, ASEE and NCES put engineering bachelor's degrees at a stable 130,000–145,000 a year, rising above 200,000 if computer science is included. Because China counts CS as engineering, the fair comparison is roughly 1.35M against 230–250k US engineering plus CS graduates. That is about 5–6x in absolute terms. Adjusted for population (1.41B vs 335M), China produces about 950 per million people and the US about 700 (1.3–1.4x more).

Even Claude highlights that the numbers aren't apples to apples and in China the definition of "engineer" is more loose. I do believe that in relative numbers, more engineers graduate in China

On lawyers:

> In the US there were 1,322,649 active lawyers as of January 2024. For China, there were around 650,000 lawyers in 2022. Which in relative terms is 8x in the US than China.

andruby··on Show HN: What if the speed of light was 5 km/h?
You're right, but not entirely.

At 1G constant acceleration reaching Andromeda would take ~15 years, or ~29 years if we also need to decelerate at the same 1G rate to not just whoosh by.

The furthest known galaxy is MoM-z14, which would take ~47 years to reach.

But unlike Andromeda, MoM-z14 is accelerating away from us, or more precisely, the space between us and MoM-z14 is expanding. It's "receding" at 726,000 km/s (= 2.4 times the speed of light). And still accelerating. Because of these, even the magical constant 1G accelerating spaceship can never reach it, not even in 1 Billion years.

andruby··on Stockfish 19
love the name :P
andruby··on PostgreSQL 19 Interactive Tour
But the payoff here is that you get a sneak peak into PG19

It's off-putting to me too. I wonder if the AI enthusiasts that stopped manually writing also find it off-putting
