patrickk··on Investors are going nuts for ChatGPT-ish artificial intelligence
Martin Skreli (yes, pharma bro) did an analysis of Nvidia recently, highlighting the importance of the data centre revenue segment to Nvidia's business. Basically they need that segment to grow and grow over the coming years, otherwise there is no real justification for their sky high P/E (crypto mining is in the toilet, many gamers already upgraded their GPUs during the pandemic, possible recession looming so fanciful overpriced GPU spending will be impacted).

> this is why i think its kind of funny that people object to the idea of Universal Basic Income, when it's already being experienced in so many aimless offices. I do think this is a gross misallocation of resources, but insofar as moral judgment goes it's not obviously less moral than many other inequities in society.

Absolutely. I've worked in multiple different companies, of different sizes, since about 2011 with breaks in between. One common theme was the amount of pointless work going on, stuff that could've been streamlined or automated, or manual reports that no-one reads or acts upon.

There’s a standard in the EU called Building Energy Rating (BER) which is disclosed when a house is sold. It’s a scale that runs from A-G, with A rating being the most energy efficient.

Anecdotally it doesnt seem to have a huge impact on the asking price.

patrickk··on Why is there so much useless and unreliable software?
Ding, ding, ding!

Cover your ass, ticking off items as launched are other areas that lead to speed over quality every time.

The OP post reads as very naive, without experience in the real world corporate politics. No one really gives a shit about most things on that list (unfortunately).

patrickk··on Perovskite-Based Thermochromic Windows Reduce Load and CO2 Emission in Buildings
You're welcome!

It's amazing what creative designs are dreamt up prior to having AC as a crutch, including examples much older than that. For example, water pools in the centre of Roman courtyards[1], which lowered the temperately passively. Another example are windcatchers common the Middle East[2].

patrickk··on AutoHotkey v2 Official Release Announcement
I realise you are giving opencv as an example of why having Python to AHK would be desirable, but for anyone wanting to read GUI elements like buttons there is ImageSearch[1]:

Also, to make it even easier to generate AHK scripts to automate button clicks, clicker games, or boring tasks requiring the keyboard and mouse, you can generate an image recognition AHK script quite easily using Pulover's Macro Creator[2]. Even someone with minimal knowledge of scripting can use it to automate Windows.

Even without Python, AHK is amazing. It gets a lot of undeserved flak from advanced users, undeservedly so in my opinion.

patrickk··on Nix on the Steam Deck
I'm aware. This time, SteamOS is much more mature and consumers are primed for such a move. Especially if it's more tightly controlled by Valve instead of allowing 3rd parties more leeway.
patrickk··on Nix on the Steam Deck
If Valve decides to make a standard ‘game console’ - miniature gaming PC with a PlayStation-like form factor, standard hardware for game devs to target, SteamOS - then add gaming consoles to that list.

There was an interview recently with someone in Valves steam deck team who mentioned that it’s on their radar but they don’t have the manpower yet to consider it. It does seem like an obvious next step, especially if Steam Controller 2 is released.

patrickk··on Ask HN: Is there a cloud music library that doesn't keep deleting my music?
iPod classics.

Iflash boards are probably the best way of enabling micro SD cards, there’s a list on their site:

patrickk··on Ask HN: Is there a cloud music library that doesn't keep deleting my music?
This kind of experience is exactly why I bought a bunch of old iPods and loaded them up with music and favourite playlists. You can mod certain iPod classics to take micro SD cards and upgraded batteries too.

Yes it’s a hassle to sync them but I retain control, and there’s no tracking and no ads. One iPod for out and about, one for the car. They’re dirt cheap for certain models nowadays.

patrickk··on Even After $100B, Self-Driving Cars Are Going Nowhere
Public transport is great, but self-driving promises to fix the last mile problem.

> But it seems to me you could do "self-driving" a lot cheaper and easier by improving the commons. Embedding sensors in the roads, street signs, and furniture - isn't that going to make more sense than turning ever vehicle into a super-computer?

This would require a broad agreement on a global standard for Infrastructure to Vehicle (I2V) and huge investments by local and national governments around the world. It could technically happen, but likely will proceed at a snails pace. As you mention, it would be much better than relying on-board sensors like Lidar and cameras as centimeter accurate GPS coordinates can be embedded into road signs etc, but it will take decades.

patrickk··on What to read to understand central banking
> So banks are incentivised to not create debt that is too-risky -- i.e. where the ratio of potential non-performing loans is too high for the interest rate they lend at, or the interest rate of raising expensive additional capital would get too high...

Thereoretically yes. However, 2008 moral hazard (heads I win, tails you lose) of excessive mortgage lending and securitisation put paid to that notion. Staff of bailed out banks were getting their bonuses again in 2009[1].

It also touches on the principal/agent problem, where bank executives and traders don't really care if the shareholders get wiped out and the taxpayer picks up the tab. They'll get their bonus and bounce to the next opportunity if the bank itself goes belly up.

Additionally, the Justice Department refused to bring criminal charges against bank exectutives[2].

So, you'll load up on risk to make excess short term profit, maybe your bank will go bust, but you'll never face charges and may get a nice bonus next year at your bank, or bounce to the next bank. Must be nice.

patrickk··on European Central Bank rises rates by 0.5%
I live in Germany, an immigrant myself. Plenty of people from neighbouring countries choose to move here, from France, Spain, Italy, Poland etc. People vote with their feet. If you can’t get a decent career going elsewhere that’s on the local employers and labour market laws.
patrickk··on European Central Bank rises rates by 0.5%
Tightening immigration isn’t easy with Schengen and other agreements with EU partners. Unless you exclusively mean non-EU migrants. I haven’t seen any proposal from the current government suggesting they’d clamp down on migration when the population is slowly dwindling and there’s a permanent shortage of workers in most industries in Germany.
patrickk··on European Central Bank rises rates by 0.5%
That’s been going on for far longer than 2008 and isn’t connected with the bank bailout.
patrickk··on European Central Bank rises rates by 0.5%
Germany needs the EU to offset their aging population and to import younger, skilled workers from neighbouring countries who share similar values. Without this, they'd be already like Japan, South Korea, etc. that is facing an even worse demographic time bomb.

Ireland was in the original PIIGS group[1] after the insane bank bailout in 2008, which skyrocketed debt levels. They've fallen since[2].

Well said. There are a handful of entities which control all the major car brands. It's the illusion of choice.

Seeing as London has been corrupted by Russian money, numerous Russians have been murdered/attempted to be murdered by the Russian state in the UK, and the current PM is the former mayor of London, it’s more than valid to discuss Russian influence in the UK.

patrickk··on Big money, nuclear subsidies, and systemic corruption (2021)
> In the long run I hope to see high capacity transcontinental HVDC lines linking continents so we can buy solar power from the other side of the Earth when it's night where we are, and sell our surplus when the sun is shining -- no batteries needed. That's hard and expensive.

There are a bunch of projects in this space. I love going down this rabbit hole.

The EU supergrid is already being built out, and doesn't require linking far flung continents since it links Norwegian hydro and North Sea wind power, among other sources. A mix of geographically distributed hydro, wind, solar, batteries and perhaps geothermal will negate the need for relying on solar + HVDC stretched around the globe along with the geopolitical risks.

> I don’t like being stalked by one. They need a little bell or some sort of noise so I know they are coming. Even if it’s just an electric engine whine. Give me something more than just rubber tires over asphalt.

In the EU at least there’s already a regulation for this:

https://ec.europa.eu/growth/news/electric-and-hybrid-cars-ne...

EVs emit a sort of musical tone at lower speeds. Although in practice it’s still not noticed by pedestrians. It must be a tough balance to get right, noise pollution on the one hand, pedestrian safety on the other.

patrickk··on Why Northern Ireland has no flag
> My understanding is that the Irish motherland has always been wary of outright reunification.

Yes, there is a lot of concern in the ROI about how the Irish state would fund everything, especially if it would be necessary to deploy military. Ireland has a minuscule military (neutral, non-NATO etc), and obviously is a much smaller economy than GB. However, there is talk that the EU would support reunification.

> They’re also a bit leery about having the DUP as a political party.

Exactly. As I understand it, the DUP would have a larger influence the the Dail (Irish parliament) of the theoretical reunified Ireland, than they do in Westminster. Since they are a reactionary, conservative party, which doesn't exist in the ROI today, it's certainly a concern.

The attitudes and situation has changed a lot in recent years, especially because of Brexit. Here's a good read:
