Heliosmaster··on Cuba is skipping its November 1, 2026 clock change and staying on DST until 2027
Fwiw last week my and my family kept our clocks in CEST. My son sleeps an hour longer in the morning. But we go to bed before 21. Aiuto!
Heliosmaster··on Mathematics of Geothermal Energy
Would you be open to do one yourself and share it? (Not sarcastic, just asking)
Heliosmaster··on Google will buy half the electricity from one of Finland's nuclear power plants
It doesn't come preloaded with fuel.
Heliosmaster··on AI's top startups are barely publishing their research
outside physics/math a lot of published research isn't reproducible at all. There's been several studies that show this.
Heliosmaster··on Škoda DuoBell: A bicycle bell that penetrates noise-cancelling headphones
I just shout "dreen dreen".. which more or less is the sound a bike bell makes, works anywhere
Heliosmaster··on Apple discontinues the Mac Pro
Yes, it's a different definition.

Enthusiast in this contest more or less means you are excited enough about something to get a level above what normal people should get and just below professional pricing. An enthusiast camera body can be 2000 euros.

I would say an enthusiast computer is 2-4k.

It really depends what you meant with minimum salary (yearly?) because paying 3 months of salary for a computer like that isn't far fetched. You're not using this to generate recipes for cookies. An enthusiast level car is expensive as well.

Heliosmaster··on European Tech Alternatives
Zoom in Veldhoven and then try to see the equivalent of ASML anywhere else.
Heliosmaster··on 3D printing my laptop ergonomic setup
That's basically what I'm telling folks. My MBP16 is fantastic in that regard. I use the integrated touchpad only
Heliosmaster··on Radboud University selects Fairphone as standard smartphone for employees
I think the alternative was to contract it out to an IT company rather than push it to the holder. Same as company phones in corporate environments
Heliosmaster··on EU court rules nuclear energy is clean energy
Apart from cities with crazy density, you underestimate how much solar we could put in the city outskirts, and it would be fine. We have already the power lines anyway to bring electricity from power plants that are far from those apartments you mention.
Heliosmaster··on Ask HN: Cloud vs. Edge Computing–Why Choose a Local NAS?
## Cloud vs Edge:

- 100% guarantee that the data I care about will still be there.

- Costs. Scaling to a few TB is already quite expensive. Some stuff i still back to the cloud, but only the most important of data (pictures of my son)

## Use Case

- Storage

- VMs/Docker/Apps: Home Assistant, Photos app (Immich, Synology Photos, etc.), and some other small stuff like that

## Performance

Running a few VMs/Docker image requires some power, but not a lot. I like that I can choose how much.

## Storage

I had for a long time a 2-bay NAS and upgraded the drives. I just built a DYI NAS and I got a Massive ATX case which supports 11-bay. Why? Because buying a drive is cheaper than replacing drives. Having an ATX case I can still run it with 2 bays, and I still have a computer case If i change my mind.

Ideal storage is a mix of HDD (WD RED, so optimized to run 24/7), SSD and NVME. Each of them is useful for something (HDD for longer term storage, as they are cheaper per gb), SSD and NVME for apps usage and caches

## OS

I was using Synology DSM, and now I went for Unraid. I'm curious to see where HexOS goes in the next few years.

## Design

I only care about noise.

## Budget

~1000 Eur

Heliosmaster··on Synology Lost the Plot with Hard Drive Locking Move
but that's the proposed change, that their Plus lineup which is generally targeted for SMB/SOHO/enthusiast market, will be working only with their drives

Heliosmaster··on Tokyo is set to introduce a four-day workweek for government employees
Yep, completely agree. After having our kid both me and my wife work 80% so we have one extra day at home. Huge.
Heliosmaster··on Tokyo is set to introduce a four-day workweek for government employees
Do you really think that being remote is "staying home with the kids"? You're physically in the same building as them, but either you're not really working, or your kids don't actually need an adult to be there because they are grown up anyway, so no childcare is needed because they go to school.

Heliosmaster··on Swift – A great language strangled by governance?
A honest question here from outside of the Swift world: why does it matter?

I'm a Clojure developer, have been exclusively one for the last 10 years and have no intention of changing anytime soon (in other words, I don't care/follow closely what the majority of development world is and what the trends are). A few years ago we had "Open Source is Not About You" [1] by Rich Hickey, basically pushing back that the creator(s) of Open Source don't owe anything back to the community. That piece has aged well for me: now I understand that something is what it is, not what I wish it was. And more importantly, the goal of open source isn't to be liked or used by everybody. It's a thing put out by its creator for others to use, and that includes Apple.

So really, why does the governance matter so much? If you don't agree with something, why not fork it and make it like you want it?

Heliosmaster··on Starlink direct-to-cell enabled for hurricane helene emergency messaging
Energetic collisions can send debris on higher orbits with significant longer time to decays. It all depends on kinetic energy added
Heliosmaster··on Why the Wisconsin pizza farm movement is an idea whose time has come
yes, any time you're burning wood you're climate unfriendly. But a lot of other things are climate unfriendly: where do you live what's the energy source breakdown? It's all renewable? Your computer was manufactured and furnaces were involved at some point: what about their emission? It's CO2 all the way down.

You should look at all of this relatively: from an absolute standpoint, humanity isn't good for the planet

Heliosmaster··on How Olympics officials try to catch “motor doping”
That story is a nothing burger. CO rebreathing is the technique to monitor hemoglobin mass changes after a period at altitude. It's a test that lasts 3 minutes and has no consequence.

It's like saying "cyclist get better by drawing blood" when they just have their bloodwork done to see how they are doing with training.

They aren't sleeping attached to a car exhaust.

Heliosmaster··on Initial details about why CrowdStrike's CSAgent.sys crashed
spaceX celebrating when their rocket blows up after a certain milestone it's like us devs celebrating when our branch with that new big feature only fails a few tests. Did it pass no? Are you satisfied as first try? Probably
Heliosmaster··on Waymo One is now open to everyone in San Francisco
But...they are a company, their goal isn't to make breakthroughs. Their goal is (eventually?) to make a profit. They'll simply use the technology and breakthroughs that allow them to get there faster. That's not cheating.. that's business
Heliosmaster··on Flow Field Pathfinding
That post has sit on my browser bar for.. well over a decade at this point. I've read it once, found it neat and put it there. Never really looked at it again, but i see the favicon every day since years and years. At this point it's part of the furniture. Anyhow, funny how stuff becomes "home" for sometimes the most random reason...
Heliosmaster··on How a Solar Revolution in Farming Is Depleting Groundwater
Pumping water is useful only when coupled with increases in water retention and runoff prevention. Like what is happening in some (arid) places like Northwest India: https://www.youtube.com/watch?v=79VUAFq2rbg
Heliosmaster··on Eating fewer calories can ward off ageing
Excercise absolutely makes you age better. Actually, it seems that in order to have a decrease in all-mortality you need to exercise quite a lot (at least 1.5hrs a day.. for the rest of your life).

Aerobic exercise of course means more caloric expenditure, which you should totally compensate, but that's not hard for regular folks who train, only for extreme athletes

Heliosmaster··on Eating fewer calories can ward off ageing
Could this just be a perception issue? When you are young you are generally less careful about what you eat, and eat a lot of calorie dense food.
Heliosmaster··on The next power plant is on the roof and in the basement
Yes, that's what's called net metering: https://en.wikipedia.org/wiki/Net_metering

However, despite being convenient for the user, it isn't great for the grid nor scalable if all users were to have solar panels. (Here in Italy solar on rooftops are quite widespread).

You can see that a kWh on a sunny summer noon when all panels the area are working well, isn't worth the same as a kWh in the cold winter night, where non-renewables often supply the grid.

Heliosmaster··on The next power plant is on the roof and in the basement
That makes kinda sense, a Tesla is mostly batteries anyway.

Jokes aside, how much batteries do you need? A Tesla Model 3 has 60kWh. That's a lot of battery. For my residential needs (I have solar panels) I would be looking at maybe 10kWh.

Heliosmaster··on The next power plant is on the roof and in the basement
depending on where you live, that's where grid pricing comes from. I live in Italy and in my solar panels I have a kind of net-metering (not quite, since I need still to pay transports costs for the energy I buy back from the grid). In a year, they will phase out this regime and every person with a solar array will become a "producer". Energy company will pay the gross market price for the energy that you feed to the grid (and this price it's updated hourly if not more often). That will essentially do what you suggest: owners will start caring more about timing, and the grid will benefit. If you still don't care and want to feed the grid at the time when everybody else is also.. well the energy won't be paid much. And viceversa
