sydd··on Raspberry Pi 5
I'm using currently 4:

- One pi4 for my homemade 3D printer (a Voron)

- One pi3 for a homemade eInk clock/weather station (here I could've gotten with sth much cheaper like an ESP32, but the Pi is so convenient)

- One pi zerow 2 for a homemade eInk radio

- One pi4 I just bought for home automation (homeAssisstant)

sydd··on There's a new map style on OpenStreetMap.org
While I love OSM the layers are bad UX. Currently the main site ( https://www.openstreetmap.org ) displays 7 layers:

- Standard -- OK, lets say this the universal default. The name is a quite non-descriptive, why not call it roads? Or driving?

- CyclOSM -- Why not call it cycle map? This is some internal project name?

- Cycle map -- duplicate, why does it need 2?

- Transport map -- What kind of transport? Call it "Public Transport".

- Tracestrack Topo -- no idea what this means.

- OVPNKarte -- again no idea. Looks like another public transport map. Why does it need 2?

- Humanitarian -- Here I have really no idea. Is this for disaster relief personnel, so it displays hospitals and such?

sydd··on Do you struggle to find ethical work?
Because you are building stuff to kill people. Even the doublespeak of naming it defence is atrocious. It might be justifiable in some cases like the current weapon shipments to Ukraine, but not if they are used in something like the Iraqi war. And you definitely wont be the one who decides where the weapon you helped to make is used.

sydd··on There's something off about LED bulbs
Because there are many more issues:

- The issue is not that they are "not the same color", but that they have a low CRI which means that they make look everything bland and greyscale.

- That they use some shitty low frequency PWM to drive the light causing eye fatigue and headaches

- That they use low quality electronics causing your bulb to fail as fast as an iridescent one that costs 5 times less.

What you are saying sounds a bit like someone complaining why people want to move on from CRT monitors.

sydd··on There's something off about LED bulbs
I'm in the same boat. For the sake of simplicity find some good brands and stick to them. Where I live its simple, get all your bulbs at IKEA. Most of them are 90 CRI and other parameters are good too. There are better ones on the market, but I dont want to go on a product hunt if my supplier is out
sydd··on Original Prusa MK4
> PC printing is really handy for intrinsically bespoke things like tools in the wood shop.

Can you name some examples? As a hobbyist woodworker I've used my 3D printer to print router templates where PLA was fine enough for the task.

> Aside from cost of development and manufacture, I don't understand developing new bedslingers

Another reason is that bedslingers are good enough for most users. If you dont try to print 30cm high columns with 300mm/s a simple bedslinger will do. I've printed my best minis with a slightly modded Ender 3 and I have a pretty high end CoreXY printer. I could tune the CoreXY one too to be on par with quality but for such stuff bedslinger vs CoreXY doesnt matter

sydd··on Original Prusa MK4
Is it really? I've looked at the Bambu Lab printer and while on paper it looks nice I would be very hesitant to buy it, their "advanced" features not that convincing:

- IMO multi material printing has always been a buggy gimmick (mostly multi material setups are very prone to failure).

- Them advertising that the printer can print "advanced" materials like PC is a gimmick too, the main issue with FDM printers is layer adhesion and no matter what material you are using its going to suck compared to injection molding.

- bashing bed slingers is wrong too, they have their advantages compared to CoreXY setups (mostly simpler mechanics)

IMO FDM printers have 2 main issues:

1. Unreliable due to lots of moving parts. A solid design with quality components mostly mitigates this.

2. Layer adhesion sucks limiting possible applications. Some very innovative non-planar printing could be a solution but it does not exist yet. Or could be solved by printing metal, but these devices are far from home use.

Resin printers solve both issues, but bring their own (mostly that resins are very toxic stuff that you dont want in your home.)

So no, this printer is in no way revolutionary (neither is the Prusa). Until both of these issues are solved home 3D printers will be mostly used to print benchies and accessories for tabletop games.

sydd··on Ask HN: How to get an accessibility tester job as a blind programmer?

sydd··on Stack Overflow questions are being flooded with answers from ChatGPT
No, you are washing lots of topics together. Just because it AI, its not the same.

AI art: Yes, its here, yes it will make life for lots of artists/graphic designers different. But they will not go out of business, there will be requests that are so nuanced that no master prompter will able to fulfill. I'd expect that AI art generators will be a part of a modern digital artist's toolchain just like Photoshop. Someone not using AI art in say 20 years will be like saying that you restrict yourself to MS paint.

AI for code: We might see something similar just to a lesser degree. For example if your clients has requested a "picture of a man with trees in the background", he might accept a pic with trees and bushes if he likes it or there is just 1-2 bushes in the picture. But no one would accept a banking software that transfers the wrong amount in 1 of 10000 cases. Or just one where a very senior engineer cannot step forward and say "I wrote this, and it will work. If it doesnt I will fix it"

sydd··on Stack Overflow questions are being flooded with answers from ChatGPT
I think the poster above meant that e.g. engineers are Meta are paying very good money so their children go to private schools where they confiscate phones. Or that they dont buy phones at all for their kids until they turn like 12, instead pay a lot of money so they go to private tutors, have nannies, do all kinds of after school programmes. Whereas kids from poor families cannot afford these or to keep watch of their kids 24/7 (because they need to work), so these kids will hang on Facebook/Youtube/TikTok/.. all day

sydd··on Shanghai Disney shuts: Visitors unable to leave without negative Covid test
AFAIK they need to lock down because their vaccine is shit. It kinda works for the younger people (around 70% efficiency compared to 90++ of the MRNA ones), but it does really bad for the most vulnerable population (80+ year olds). They either lock down or have tens of millions of deaths.

Xi said that they will end lockdowns in 2024, the same year they will come out with their MRNA vaccines. I dont know why they arent buying western vaccines though. Trade restrictions? Xi's pride?

sydd··on Why is hydroelectricity unfashionable?
Because lots of mined metals come either from 3rd world countries like Congo with no environmental protection laws or are mined in few places like Russia where a trade war can lead to shortages.

Hydro requires the most common mayerials like steel or concrete.

sydd··on Mcmaster.com is the best e-commerce site I've ever used
Conrad is a shitshow in my country.

- Almost nothing is on stock, most items have 10+ weeks backorder time.

- Ridiculously expensive, its common to find 2x prices than in other shops.

- Full with Chinesium crap (but some high quality items too), one can never be sure what they will get.

Its like a shitty Aliexpress

sydd··on Ask HN: Should I be panicking about jobs in Europe?
> Didn't the EU leaders botch the most recent global crisis, the Covid pandemic?

I would not say so. Compared to most other countries the EU did very well:

- Got the best vaccines with the 2nd fastest (USA was better because the EU did not mandate Pfizer to build a factory in the EU, thus Trump could block most of the vaccine exports for a few months until the USA was mostly vaccinated). Compare this to e.g. China where they still have to do lockdowns, likely because of their subpar vaccine that is ineffective in the elderly. Or to Japan where like 2% of the population was vaccinated by the time of the olympics.

- Was among the best for keeping the virus under control until it was not necessary with the right amount of lockdowns. For bad examples see Russia where lockdowns were not enforced/declared too late or Brazil where they declared it a hoax.

So who did better?

- Israel with securing the very first batch for a price of playing guinea pigs, which was a big gamble.

- Island states like New Zealand or Australia because they can just lock down airports and ports to prevent spread. EU could not do this, too many land borders.

Compared to some ideal world where we would have a global lockdown for 2 weeks and the virus is gone everyone was doing pretty shitty of course. But compared to other countries EU was among the best.

sydd··on Ask HN: Should I be panicking about jobs in Europe?
> What does it mean to "afford" the burden and be "fine"?

That the EU has 2 choices in the long term:

1. bow to Russia's demands and lift the sanctions. Gas will be turned on and its price will fall, but now Russia knows that they have a weapon that they can and will use against the EU when they see it fit. Also it would result in a huge uproar, most EU states are very pro-sanctions despite the hardships.

2. Do not lift sanctions. In this case the gas price will stay high, but will certainly fall long term. Also Russia will have no leverage against the EU. Also the situation is not so dire as it seems: Russia supplied ~15% of the energy to EU, so if the EU can lower its energy demand by a bit and get a bit of energy from extra sources they are set. People did the math and its possible, likely in 2 years there will be a minimal effect of no gas flowing from Russia.

As for the "hard years", its not just the energy crisis caused by Russia turning off the gas valve: After the constant boom of the 2010s its time for the bubble to burst. Global warming effects are starting to hit hard, the supply chain issues starting with COVID and getting worse with the war made governments realize that you cannot outsource everything; moving back production to the West will casue lots of price hikes. Also boomers are now starting to retire causing the most experienced part of the workforce to shrink drastically and being replaced by pensioners who just cost states money.

So no matter what we do with Russia the next 15 years will be hard -- I'd say that the belgian government was optimistic with the 5-10 years estimate.

sydd··on Ask HN: Should I be panicking about jobs in Europe?
> NS1 by sanctioning Russia so they can't work with the companies that repair the broken components.

Not true. While Canada who repaired the turbine first refused to give it back to Russia now they are willing because of German pressure. Siemens (the operator of the turbines) has stated multiple times that there is no technical issue in running NS1. Russia is not supplying gas trough NS1 because of political reasons:

- Russia's main goal is to make the EU stop supporting Ukraine, thus they can make a favorable peace agreement. Their main goal is to get the EU states oppose the war.

- They are doing this by trying to sow panic and chaos in the EU by turning NS1 lower and lower (now its off) and other things like releasing ridiculous videos like https://www.youtube.com/watch?v=kcbcBrL4ju4

- This panic also results in high gas prices which is harmful to EU's economy and good for Russia's pockets.

The west should not bow to Putin's will, if it would lift the sanctions Putin would use gas as a weapon against the EU whenever he wants; the only good choice is to get rid of any Russian dependency.

Trust the western leaders, they did the math. The EU will have enough energy for the winter. Also USA is bringing out the big economical guns too, they started to lower the price of oil which will result in crushing Russia's #1 income source (they can produce oil for around $50) and this will also bring down energy prices.

This and the next winter will be still hard for the EU, but after that things will stabilize. But seriously what did you expect, how could a Russia, a country with a total GDP around Italy beat the EU, Japan, USA, Australia, South Korea in an economic war?

sydd··on Ask HN: Should I be panicking about jobs in Europe?
Australia is happily selling any amount of coal to the EU because they are in a trade war with the Chinese who refuse to buy their coal.
sydd··on Ask HN: Should I be panicking about jobs in Europe?
I would not be so worried. While the situation is not so rosy, Nordstream's closing will be compensated by using less energy generally (e.g. not heating up gov buildings, lots of people working from home etc.) and from dozens of other sources (importing more LNG, letting nuclear plants run more, firing up coal powered plants etc)

Russians are very good as sowing discord and creating panic among the population, but if you look at the facts things are not so bleak.

- If closing down Nordstream would really lead to the collapse of the German economy then the EU would have lifted the sanctions. While they can accept some hardships to beat Russia, they would not kill their economy to do so.

- Just look at the gas futures price in the EU: https://www.theice.com/products/27996665/Dutch-TTF-Gas-Futur... Since the full closure of Nordstream gas prices have actually gone down showing that the gas market has already priced the closure, and as time will pass it will go down even more (since people will see that we have enough gas & Putin's threats are taken less and less seriously mostly because he has run out of things to threaten with)

So dont panic and trust Western leaders a bit more.

sydd··on Inky Impression 5.7“ – Colour e-ink display for Raspberry Pi
The issue is that the eink company has a monopoly in the market mainly due to them owning lots of patents. Also they seem to be only caring of the wholesale market, thus their new tech for the DIY/hacker crowd arrives always with a significant delay.
