Heliosmaster··on Starship will attempt a launch this Friday
generally when two satellites collide some debris can be shot at a higher orbit which will take forever (or will not) reenter atmosphere.

See the scatterplot of debris for the Chinese collision test of 2000: https://en.wikipedia.org/wiki/Space_debris#/media/File:Gabba...

See this video for evolution of debris and altitude over time: https://www.youtube.com/watch?v=mQT5aMa_7iI

Heliosmaster··on Home Assistant 2023.11
yep, through the UI. the update went fine, the system afterwards didn't work properly though.. :(
Heliosmaster··on Home Assistant 2023.11
I don't think the problem is how to update: it's easy enough in the interface, it just works. The problem is whether after the upgrade you suddenly don't see the heater anymore, or another device stops working.
Heliosmaster··on Home Assistant 2023.11
I love Home Assistant. I only started using less than a month ago (moved into a new house).

However, the two times i needed to upgrade Core (I use Home Assistant OS, their recommended installation procedure), it broke.

The first time they had changed the spec of the 'correct' way of the YAML config file. Which means I didn't have an integration until i fixed the file manually (they deprecated something not gracefully).

The second time I don't know: I couldn't see anymore my Viessman Heater and check everything related to my hot water / heating so I gave up and rolled back.

I am a Clojure developer where there's almost never breaking changes, so this is a good reminder to not take that for granted. I think this is an aspect they have to improve a lot, if they want to cater to people who don't want a new hobby.

Heliosmaster··on Home Assistant 2023.11
I use what they recommend: I installed Home Assistant Operating System on a Raspberry PI 3. Which still means there's an OS and there's HA Core.

> Home Assistant Operating System: Minimal Operating System optimized to power Home Assistant. It comes with Supervisor to manage Home Assistant Core and Add-ons. Recommended installation method.

I tried on purpose to do everything as 'basic' as possible because I don't want to spend time making sure it keeps working.

Heliosmaster··on Home Assistant 2023.11
I've only recently (less than a month ago) started to use HA and I have polar opposite impression from you.

I gave up on updating because the 2 times i updated the HA Core package and the OS most of my integrations broke. The first time i bothered changing the config. The second time I decided to rollback and keep everything as is.

Heliosmaster··on Ask HN: Why is LK-99 public?
it's simply not published in a peer-reviewed journal, but it is published on arXiv, as per definition of 'publishing', i.e. "the business of making books, magazines, or newspapers available to the public" (https://dictionary.cambridge.org/dictionary/english/publishi...)
Heliosmaster··on Sigh, this is what browsing the web in the EU looks like nowadays (2021)
I think most of the comments here right now are missing the point of OP's post. It's not about one thing in particular (cookie consent), just that the whole ordeal is full of ads and popups (one of which is the cookie consent popup).

Most of this crap is the same everywhere, not just in the EU.

Heliosmaster··on Don't believe the hype: why ChatGPT is not the “holy grail” of AI research
As far as I understand, LLMs with 95% correct answers are much more useful than a car that doesn't crash 95% of times (if you need to pay attention to correct mistakes, you may well be driving).

A 95% correct LLM might be utter garbage in some areas but nearly flawless (thus reliable) in other, menial and time consuming tasks, such as summarization, rewording, providing new ideas, etc.

Heliosmaster··on EU Passes Law to Switch iPhone to USB-C by End of 2024
From the text of the Proposal:

> With respect to charging by means other than wired charging, divergent solutions may be developed in the future, which may have negative impacts on interoperability, consumer convenience and the environment. Whilst it is premature to impose specific requirements on such solutions at this stage, the Commission should be able to take action towards harmonising them in the future, if fragmentation on the internal market is observed.

So they left the door open to regulate also Magsafe etc.

Why do you think an investigation has to be done on devices available to the public? Prototypes exists.
Heliosmaster··on Open source is not about you (2018)
His reply has been deleted from GitHub, but can be found on the Internet Archive: https://web.archive.org/web/20190206101354/https://gist.gith...
Heliosmaster··on Open source is not about you (2018)
I would phrase it that open source is just about the license of code, not about anything else, and definitely not about how changes are applied to such code.

Usually, it just practically means that you are allowed to make changes and redistribute them, but without giving any guarantees on how these changes are going to be made available to others.

Heliosmaster··on EU Digital ID wallet is coming
Each country has their own system. in NL we had DigID, and apparently now iDin (first time i hear about it). In Italy we have SPID who uses a bunch of external providers (phone companies, italian posts, internet providers, ...). The whole idea is to create an interoperable standard.

I'm not sure whether you're being sarcastic, seeing who owns HN...
Heliosmaster··on Why are semi trucks in the US and Europe so different? (2018)
Or rail, which is vastly more efficient than trucks (which then could be used only for last-mile)
Heliosmaster··on ASML reports fire at its Berlin factory
a competitor won't be enough, the whole supply chain is made by companies which are single point of failure (the reason why europe can't afford to say "ASML only sell your machines to EU fabs" is that one of the key ASML supplies is US.. and without them no machines...).
Heliosmaster··on ASML reports fire at its Berlin factory
keep in mind that machines like those are so complex that you don't simply buy them and install them.

It's more like getting custom-made artisanal goods: each machine has a "father/mother" from its 'conception' til delivery who treats it as their (work) baby. Then a special plane will fly the machine and a team of dedicated engineers will spend weeks in your fab doing install / validation. The process is long and complex.

Downtime are really painful and expensive so the philosophy is "better copy paste the code rather than change what's working". downtime are not very frequent but people are just the least expensive / worrying thing there. It's not like you can easily start a competitor...

Heliosmaster··on ASML reports fire at its Berlin factory
yep. accurate comment. How do you like 40M LOC with 50% code duplication?
Heliosmaster··on ASML reports fire at its Berlin factory
As a person whose first job after graduation was at ASML, and left after 6 months, if you like software I don't think it's the best company to work at.
Heliosmaster··on Tor Snowflake Proxy
The issue is that whether a VPN is reputable is hard to gauge and not fixed in time.

Take IVPN from example: from what I gather they are among the most reputable. They haven't fucked up yet (a-la Nord VPN), they support and fund anti-censorship activities etc. But all of this is based on a perception, that can be doctored if you're determined enough. And usually in the discussions about VPNs the level of paranoia is pretty high to be trusting others.

Furthermore, the real issue is that VPNs are not that widespread among the "general public" so compromising a VPN (or running a fake one) seems like a good target for those who want to get at the (current) typical users of VPN.

Heliosmaster··on Tor Snowflake Proxy
I'm not so sure about your argument: the usual argument against a VPN is that you are trusting effectively somebody else's computer. They can have all the business incentives in the world, but we know that some states go knocking on doors with gag orders. A 5$ wrench (or its threat) can get a long way.

The point is that we can't easily know who is compromised and who is not. There's always a certain level of trust required. The argument is that if you host your own VPS and use that as exit-node, at least what you're buying is more generic and the VPS provider most likely wouldn't care. But again, it's a matter of trust.

Heliosmaster··on Omicron variant more resistant to vaccine but causes less severe Covid: study
Yeah, technically a variant who lies dormant for a long time while spreading slowly is a better fit than one that is noticed.

Didn't we learn anything from Plague Inc?

Heliosmaster··on Omicron variant more resistant to vaccine but causes less severe Covid: study
> Was any variant successfully stopped with lockdowns?

Statstically speaking, almost surely yes: with millions of infections there are thousands of variants, every day. If somebody was prevented from infecting somebody with their variant (as patient 0) technically we stopped variants with lockdown. Maybe they more favorable for us, maybe they were more dangerous from us.
