mglz··on DOGE's government cuts may hurt business, companies warn investors
> I just want models to a focal point of discussion rather than some poorly-explained textual interpretation.

Do we have any economic models which managed to predict any non-obvious, relevant things?

mglz··on Learn Arabic
You might be understood, but understanding others is where you run into problems :(
mglz··on 50 Years of Travel Tips
Luggage tipp: Have exactly one, easy to grab main piece at luggage that goes on your back or on wheels. Have at most one tiny extra piece to carry. The second your luggage exceeds three it becomes a massive hassle: You cannot hold on to things, you will lose one piece and your fun trip descends into a disorganized mess.

Luggage which clips together like a storage/day backpack combo is very valuable for this: Your backpack might be comically large, but you can haul all your stuff with free hands. At your accomodation, you can leave the large bag and continue on your day pack.

Free hands are critical when travelling by train or bus, or if you just wanna get a snack and drink.

mglz··on First Look: Loops, by Pixelfed – Decentralised TikTok Competitor (2024)
In these systems you pick what you see and don't rely on a third party algorithm for that. If one instance allows the publications of things others disagree with defederation is an option.

Under no circumstances should we let AI filter the fediverse. Freedom is worth more than mild offense.

mglz··on What other communities do you use apart from HN?
Lemmy caught traction and feels like the old intrnet sometimes.
mglz··on All clocks are 30 seconds late
Hä?! A clock shows the period of time we are currently in. A clock only showing hours would for example indicate that we are in the 14th hour of the day, for the entire duration of that hour. That is not an error. Similarly, a hh:mm clock will show the hour and minute we are currently in for the duration of that minute.

No clock can display the exact current moment of time. That would require infinite digits, and even then those will be late, since lightspeed will ensure you recieve the femtoseconds and below really late.

mglz··on Long Fatigue: The exhaustion that lingers after an infection
Why do you focus on the vaccine and not the novel, highly virulent virus which has killed tens of millions and disabled hundreds of millions? What makes it more likel for you that the vaccine causes this and not the virus?
mglz··on Yi Peng 3 crossed both cables C-Lion 1 and BSC at times matching when they broke
> This happend a very, very long time ago.

It happened on 26. September 2022. That is not a long time ago.

> It seems like a pointless attack that achieves little other than reminding the world that horrible, oppessive governments are dangerous to everyone

It sends a message, as sabotaging communications is frequently done before an attack. Also it damages morale and is a show of power.

mglz··on Honeybee gene specifies collective behavior, research shows
Fudnamentally the genes have to code for a biologicaly system that is able to adapt its behaviour well enough to allow for dynamic behaviour while also keeping it on guiderails to make it function as a bee. Importantly a bee emerging from its brood cell immediately gets to work without any training. Where does this information come from if it is not genetic?
mglz··on Millions may rely on groundwater contaminated with PFAS for drinking water
If it's bad and we avoid it = win

If it's bad and we don't avoid it = potential disaster

If it's no problem and we avoid it = Some unnecessary losses

If it's no problem and we avoid it = No problem

Currently, considering past patterns, it looks like PFAS are problematic and the potential cost of failing to mitigate could be very high. So being more cautious is the rational solution, even in the face of uncertainty.

mglz··on Millions may rely on groundwater contaminated with PFAS for drinking water
The problem is PFAS are in basically all the water on the planet and persist in the body for several years. Even if they might have a small effect that will likely be magnified due to accumulation and the long persistence. We have had very similar scenarios before (lead, asbestos,... ) and they had horrible consequences. This is the time to get ahead of this cycle.
mglz··on How can this 6 axis robot have a static accuracy of 0.05 mm? (2021) [video]
No, but you will almost certainly not get the required torque for a robot arm.
mglz··on US probes Tesla's Full Self-Driving software after fatal crash
> Why is he trying to buy a president in the first place?

Because he can make more money under one than the other.

mglz··on US probes Tesla's Full Self-Driving software after fatal crash
The underlying problem is that the current FSD architecture doesn't seem to have good guard rails for these outlier situations you describe (sunlight blinding the camera from just the right angle probably?) and it is probably not possible to add such rules without limiting the system enormously.

Fundamentally driving consists of a set of fairly clear cut rules with a ridiculous amount of "it depends" cases.

mglz··on Knocker uppers: Waking up the workers in industrial Britain (2016)
> Following that train of thought back one can go all the way to the Roman Empire which used slaves as proto machines as you call them.

All the way to the deepest depth of history actually: Sumer and Elam left behind records of slavery and later on in Ur we find laws seting up a framework for slavery.

mglz··on NASA Drops Boeing Starliner from Upcoming Missions
Wasn't it also supposed to go to the moon station for Artemis? Or is that also a non-starter if Starship works out?
mglz··on California police aren't loving their Tesla cop cars
> say a reliance on unsecured charging stations makes officers vulnerable when it comes to transporting suspects long distances; and note that in a firefight, police are taught to hide behind a car’s engine block

I am a diehard EV proponent, but it's important to admit that there are places where EVs are not the right solution. Especially in vehicles which take part in emergency response, the high energy density of fossil fuels is absolutely a benefit.

mglz··on Germans decry influence of English as 'idiot's apostrophe' gets approval
People get upset about this while you encounter statements like "life your live" regularly, sometimes even on TV.
mglz··on Nobel Prize in Physics Awarded for Machine Learning and Neural Networks
Hm, they have to fit them into Physics, Chemistry, Medicine, Literature, or Peace. I guess physics is the closest they can get without a gross missplacement? (Although you might be able to absue literature for LLMs?)
mglz··on Too much efficiency makes everything worse (2022)
> I have a pet theory that the state-planned economies failed not because they were inefficient

Well, a lot of it was corruption. A sufficient level of corruption can destroy almost any system, even if it had a well-meaning leader at the top.

mglz··on The quest to build a telescope on the moon
> On the Moon you can do the simplest thing that works and if it works at 10% efficiency and breaks after 1 year - so be it, if it's enough time to get resources to make a new one.

The opposite it true: You can throw away things on Earth and have local industry produce replacements. You cannot cost-effectively bring equipment to the moon since you have significant launch costs. Optimizing for light-weight and reliable machines is inherently costly. There is no escape from gravity here.

> That's all fine if it means it can work with lunar materials only.

There is no manufacturing capability on the moon and you need to price in the cost of setting up such an industry through the bottleneck of lauches.

mglz··on As IBM pushes for automation, its AI simply not up to the job of replacing staff
The "AI will automate it and we can let go of knowledgeable humans" requires a very naive and sinister mindset, which seems widespread among so called leadership roles. If you ask yourself how a rational person could make such a overcommitment to an unproven technology, the answer is: They are not being rational.

Why are they in leadership roles? No clue.

mglz··on The quest to build a telescope on the moon
> Earth seems a much hairier environment.

Absolutely not. In space you have to dela with things like radiation, extreme temperatures, or cold welding of joints. Energy supply can be a big issue depending on your environment. On the moon you have to deal with extremely abrasive dust.

The most critical issue in space is how difficult it is to fix things: If you can get a human there, they will be constrained by airlocks and space suits. In most cases it will be impossible to get anybody there and you need to construct 100% reliable or self-repairing machines. This is extremely difficult.

mglz··on The unknowns surrounding the mysterious rise of cancer in young adults
The article seems to skip over the pandemic, which has changed behaviours significantly. Also, the Coronavirus itself is suspected to promote cancer [1].

mglz··on Tupperware files for bankruptcy as demand slides
> Nobody sane

You'd be suprised by the amount of people who haven't got the memo.

mglz··on Tupperware files for bankruptcy as demand slides
People are also more aware of plastics in their food and using plastic tupperware in the microwave might add a large amount of plastic to the food [1]. Due to this I also switched to glass containers, which are also easier to clean.

mglz··on Intel aims to turn foundry business into subsidiary to allow for outside funding
Outsourcing core engineering faculties went great for companies like... checks notes ... Boeing.

In all seriousness, is there anything more to a move like this than bookkeeping?

mglz··on OpenSCAD: The Programmer's Solid 3D CAD Modeller
OpenSCAD is amazing, especially for highly detailed geometry. Fusion360 was crashing when I modelled a honeycomb structure of ~2000 cells, while OpenSCAD easily handeled a similar model.
