bkor··on Launch HN: Electric Air (YC W23) – Heat pump sold directly to homeowners
> The heat pumps I have seen personally in Europe are geothermal, very big, and very expensive.

In NL I saw loads of water/water heat pumps (so using geothermal) in plans for new buildings. The latest plans now seem to prefer air/water. The air/water is cheaper and the units nowadays are much quieter than they used to be. This is just my observations, I could be way off.

> IIRC: heat pumps aren’t even available for sale in many markets

If you've installed an airconditioning system which can cool and heat up your home you've installed a heat pump (air/air). They're hardly magic.

> I hear a lot of horror stories from the UK about this, that people pay upwards of £500

£500 for what? Total cost for a month? A year? The monthly average of a full year of costs. The monthly average cost thing is common in NL; people often have no clue other than knowing the monthly average cost. And it's often estimated beforehand by the energy company. It's assumed to be correct.

Anyway, people need to check the SCOP instead of figuring out if it is efficient (COP) at a certain temperature.

> On that note I think biopropane will be the solution for Europe.

Oh please no.

On UK, I was in Scotland. I thought the homes in NL are often terrible quality. Scotland was another level. Pretty much no insulation, terrible windows. Really drafty. Yet the media (as a result the public as well) hates the "Insulate Britain" movement.

bkor··on What happens when you open a terminal and enter `ls’
Things you might want to add:

a) Escape sequence to set the "dynamic" terminal title

b) how e.g. GNOME notifies you that a long running command has completed

c) how e.g. GNOME asks if you are certain to close a terminal, but only in case you're not in a shell

d) maybe readline or /etc/inputrc

e) bash completions maybe? it's sort of in there already

bkor··on Flexport slashes 20% of global workforce over weak 2023 volume forecast
I still don't get the bit where you say 2 high is standard. It's not. Though US port infrastructure is special, it's very outdated/inefficient compared to pretty much the rest of the world.

> The labor cost is often huge.

In a big company it's often a hassle to pay something to a "new vendor". It usually takes a long time.

> If you don't prevent fraud at the $500 level you'll have two problems

I had a colleague who used to work in the Auditing section. He had various stories of people committing fraud (stories of 50k USD+). There's a cost to trying to prevent all cases of fraud and that might hurt more than to try and prevent everything.

I've also heard cases (not from the auditing guy) where a vendor notified that we paid them 1000 times too much (caused by an input error with the , and the .). That happened despite several layers of checks.

> At a "really big company" the labor cost of paying an invoice might be $2000.

At a "really big company" if something is a good idea then it'll get done. And those handling administrative tasks are often "outsourced" to cheaper countries, e.g. India/Philippines/China/etc.

There have been several donations to "good causes". Those were handled without trying to figure out the cost of someone working in an entirely different part of the world and company. This as it's not like someone will specifically will be hired, or it really matters.

They usually made an event out of an donation (e.g. handing out something in person in an office). Funny enough the event surrounding that was often poorly attended.

> that's $750 of labor costs just to have the dev team possibly agree to support urllib3

You're not talking about a donation any more.

bkor··on Elon Musk’s $44B education on free speech
> They have a run rate > 4 billion a year even after all those layoffs?

I highly recommend reading the following article:

https://www.npr.org/2022/11/30/1139964806/how-elon-bought-tw...

Elon Musk bought Twitter with "loans". The interest of those loans are now a responsibility for Twitter. Meaning did NOT have a huge run rate. The leveraged buyout caused this.

There have been an insane amount of focus that the huge predicted losses are a result of lazy overpaid developers. This while ignoring that Elon Mush did a leveraged buyout. The number of employees wasn't the issue, making Twitter responsible for billions in loans while the interest rate of those loans went up is the problem.

Elon Musk keeps complaining about the federal reserve and the interest rate. He's complaining for a reason. He gambled and couldn't back out.

FOSS isn't about it being free though. You've already stated the issue:

That doesn't mean FOSS is has as a moral to not charge for software.

bkor··on Airbnb’s design to live and work anywhere
> Banning short-term rental properties feels like a quick bandaid to gain political points, not a solution to a market with a large demand.

Seems more that you want government to facilitate running a business where it's not in the interest of that government, nor in the interest of the locals. Airbnb's aren't beneficial, plus they aren't checked as properly as a hotel.

Usually it isn't banned, what they're after is that it is limited (days/year), plus the AirBnB income is properly taxed.

bkor··on Airbnb’s design to live and work anywhere
> The liability is with the person, not the company.

Why would the liability be solely with the person? Especially if that company has a representation in the other country I highly doubt this.

In e.g. NL the company has to "take care" of the employee. A company cannot just ignore such a question, or take it as "not my problem".

That just implies that the origin country (UK) is ok with someone working remotely. You're still bound to the laws of the destination country. Further, there's a difference between what's easily possible (nobody will easily notice if you work from another country on a tourist visa) vs what is legal.

There are separate arrangements for touring groups. However, if you're not from the EU then good luck. You'll notice that there are huge complications after brexit. That said, likely nobody will check, care or notice.

> My understanding is, for an American in a EU country, is they can go and work remotely there for the 90 days as long as they are not conducting business in said country.

That's not legal. To work in the EU you need a work visa. Though they ignore the business trips. What's legal and what's checked are different things.

E.g. new foreign colleagues need to get a tax id in The Netherlands before they do any work. Doesn't matter if they came from the US.

bkor··on France ends gas heaters subsidies
> All of the aggression on Ukrainian can be traced back to them moving closer to the EU, NATO, and putting western hardware on Ukrainian soil.

That's what Russian propaganda keeps saying. But they ignore the huge amounts of gas that was found in the region of Ukraine that was annexed by Russia. Further, Ukraine gave back their nuclear weapons. Meaning, Ukraine already acted to demilitarize.

Ukraine moving closer to EU and NATO can be traced back to Ukraine finding huge gas reserves in 2012 and Russia attacking Ukraine in 2014.

bkor··on France ends gas heaters subsidies
> what will happen in developed country if it can't get gas to produce fertilizer

In Netherlands various farmers invested to switch from gas to alternative sources. These farmers are now way more competitive than before. Netherlands leads the way in technology around farmers. Farmers have huge expenses, these expenses can be reduced by investing. Some invested, some didn't.

What would help is to have more guidance around this. That not every person (and e.g. farmer) needs to figure things out on their own.

bkor··on France ends gas heaters subsidies
> and ensure that her home is properly insulated.

Netherlands is planning to get rid off gas for a while. I've attended a presentation by the city. They planned to spend 12.500 EUR per house to switch to an local heating plan. Basically a source of hot water will enter the home. This pipe is way bigger than a gas pipe, this is why 12.500 EUR is needed per home.

They mentioned that likely you'll pay the same for heating as before.

I find it bonkers. With 12.500, why not insulate and maybe prepare it for a air/water heat pump. The radiators on really old homes will need to be replaced with ones that work with a low temperature. Walls need to be insulated, windows and window frames likely need replacing. Still, it's way better to be more energy efficient than to spend 12.500 EUR per house (of which 11.500 will be "subsidized") than asking people to change things without actually improving their homes.

The problem doesn't seem to be the money. The problem is that idiotic solutions are suggested. Plus that whatever is subsidized goes up in price. E.g. a air/water heat pump costs way too much.

> And yet, somehow, they seem to function as humans

I know various people who work in shifts. It's really bad for your rhythm. It takes months before people find a way to deal with the effects. It's worth it due to the additional money they earn, that's it.

bkor··on How we broke the supply chain
This "article" looks at a problem and tries to guess what the causes are. This without actually checking if those guesses are correct, or knowing too much about why the US is so much more troublesome than anywhere else.

e.g. it completely skips over the reliance on chassis to do anything on a US terminal. Anywhere else in the world and the terminal setup is quite different. Another issue is that most other places in the world work 24/7, unlike US terminals. This is coupled with a really strong but strange union (preventing any changes) on the US terminal side, while trucks are more or less abused.

It complains about things (globalization) that on its own aren't bad. What's bad is that various governments did nothing to prevent that only a few benefitted from that globalization in e.g. US/Northern Europe.

Then it points towards some law that's a US law and not global. It's a bit strange to ignore China->Europe trade.

bkor··on How big was the Tonga eruption?
I noticed the same on all in Aqara Zigbee temperature/pressure/humidity sensors. They're all inside, I could still easily see it twice (many hours apart). Though I only noticed after someone in a Home Automation topic mentioned seeing the effect ;)

Nothing fancy was needed for this, the sensor I'm talking about is battery operated. I have this one: https://www.zigbee2mqtt.io/devices/WSDCGQ11LM.html or this one: https://www.zigbee2mqtt.io/devices/WSDCGQ12LM.html (they look alike too much).

bkor··on The story behind Flexport founder's supply chain tweets
To add: 14k TEU capacity is considered tiny nowadays. The biggest vessels are 20k+ TEU (e.g. 22k).

A 40' container is either 2 or 2.25 TEU. The .25 is when the container is a bit higher than standard. Though nowadays loads of containers are a bit higher. The extra .25 is ignored in various cases (basically when it doesn't matter).

bkor··on The story behind Flexport founder's supply chain tweets
It's a misleading statement. The terminal isn't accepting the empty. That's a different business from the shipping line.

What likely happens is that the shipping line is sending these charges out automatically (global systems, huge company, etc). Which are then usually disputed as the terminal isn't accepting the empty.

The story makes it out that a shipping line is behaving more strangely than what happens in practice.

bkor··on The story behind Flexport founder's supply chain tweets
If the terminal is really slow the first thing a shipping like will leave behind is empty containers. US terminals are dead slow and often do not work 24/7. Their union is unique, it seems to be a show of power instead of making sensible decisions.

There's a huge backlog of vessels that need to be handled. Usually you have space on the vessel to bring back the empties, normally the reason not to do that is if it takes too much time to bring them on board (terminal is slow or vessel was late). If it was due to too many vessels it could've been solved by sending a vessel purely for empties. But there's a huge backlog in vessels to be handled. Productivity increases usually take quite a while to materialize.

bkor··on The story behind Flexport founder's supply chain tweets
US ports are highly inefficient. They don't work 24/7. That's rather unique. Same for how the terminal is organized.

I'd suggest checking Felixstowe. Various years ago they were quick. They changed their terminal system. After that they were utterly slow (still are). Due to UK importing way more than what they export, Felixstowe always has way more empties going back than full containers.

However, Felixstowe works 24/7, plus they apply pressure on shipping lines the various times they are overwhelmed with empties.

bkor··on The story behind Flexport founder's supply chain tweets
Foldable containers are investigated every few years. It's usually not worth it. There's a few savings in one area and enough costs in other areas to kill the business case.

The idea comes up at every "innovation" session. After which the responsible department shows then the last study they did (study is repeated every few years).

bkor··on How Microsoft reduced Windows 11 update size by 40%
> Linux and BSD have had this for ages.

Fedora/GNOME prefers to install updates during a reboot. So although most updates can work this way, it's not always the case.

There are some minor cases where a reboot is better, or where an update requires a bit of work. E.g. Firefox updates, but also I sometimes have that video playback suddenly breaks (not sure why; kernel/mesa/something). Only a reboot seems to fix the video playback and it happens in various applications once it breaks (Firefox, mpv). I install the updates via dnf via cron/systemd (forgot what I did), so not with the suggested reboot and so on.

I do appreciate the Flatpak bits, those update easily.

> A hyper efficient, fully electric bus system.

Cars aren't efficient. The zoning should be such that things are close by enough. Then with proper cycling infrastructure you can just go by bike. As a result you'll need way less road. As cycling infrastructure is cheap and road maintenance is costly, it'll reduce expenses for e.g. cities.

> European cities with decent public transit.

I'd rather have the mix of public transport, bicycles and roads. Combined with proper zoning. Loads of electric cars just increases demand for a highly inefficient transportation method.

bkor··on Data exfiltration in Keepa Price Tracker
I knew it was doing that as well (the distributed scraping the article talks about). But I cannot figure out where I read it. Maybe they used to have it somewhere on their site, and now it's gone?

What is strange that people asked for e.g. Amazon.nl support. This isn't implemented as Keepa relies on Amazon (this is their answer in the forums). But if they scrape, why do they still need Amazon?
