@aakashgupta This is a false comparison. By your own admission EU dryers use less energy per cycle (as you mention this is the reason they are more expensive). These are already long time in place (stricter every couple of years), so most dryers are more efficient in the EU.

Every European drying rack is the answer to a math problem Americans never have to solve. Spain residential power runs €0.29/kWh. Germany €0.38. Texas runs $0.13. A conventional dryer eats roughly 4 kWh per cycle, so a single load costs €1.16 in Madrid vs $0.52 in Houston. Five loads a week, 52 weeks, you're at €300/year in Spain vs $135 in Texas just to spin a heated drum. Stack the appliance economics. EU energy efficiency rules pushed cheap vented dryers off shelves years ago. The replacement is the heat pump dryer, which uses 50-60% less energy but retails €800-1500 vs $400 for a US vented unit. Worse upfront cost, worse running cost. Then the apartment constraint. Most European flats don't have venting infrastructure and don't have a dedicated laundry room. The washer sits in the bathroom or kitchen. There's no space for a second machine even if the running cost made sense. The drying rack costs €30. Lasts a decade. Uses zero electricity. What you're looking at is a household that ran the numbers and refused to spend €2,000+ over ten years to dry clothes 6 hours faster than physics does for free. The Texan at $0.13/kWh in a 200 sqm house was always buying the dryer. The Spaniard at €0.29/kWh in an 80 sqm flat was always buying the rack.

@realEstateTrent Our fixes (both working). Take one afternoon in the week off (work a bit less/longer the other days). Cook for multiple days. Don't wash kids everyday (not needed). Cleaning up while chatting/playing with our kids. Hope you find your way in this.

Been chatting with my wife about an issue I want to solve, but am a bit stumped -- so thought I would ask the question here, and maybe get some ideas: We both work full-time, and have two young kids at home. Our nanny leaves at 5pm, and then I get home a bit after that. We play with the kids for about an hour (while my wife makes them dinner), have dinner, and then we each give one of them a bath, and help put them to bed. By then it's around 7pm, we're both completely exhausted. We would like nothing more than to enjoy some downtime the rest of the night after a long day, but the work is just beginning. The kitchen and dining areas are now a mess from dinner, the dishes need to be done, and food needs to be prepared for the kids for the next day. By the time all of it is done, it's after 9pm, we are beyond exhausted, and the day is essentially over. We have a cleaner that comes to the house twice a week, but of course wraps up well before 6pm. What do other people do to solve this issue? How do you win back your free time after the kids go do bed, without leaving a mess overnight and ensuring they have food ready for the next day?

Spent the flight yesterday reading the full reference material for Nushell and now it's my default shell on Mac+Linux. I previously used Fish and have absolutely nothing bad to say about it, this is an experiment to try something different. I'll report back in a month or three.

@JoeFalinski @donwinslow What leverage do you think the USA has? Canada has friends, the USA is burning all their friends right now. That will leave an imprint on the current generation.

@seatedro In the same module: optimize calculating an averaging image filter over an array by going over it: for x for y ... end end. When they find out what the effect of for y for x ... end end is 🤯

@Moorlag @bunq Bizar idd. Ik zag de bui al een paar jaar geleden hangen. Na de prijzen opeens omhoog gedaan te hebben, en mensen daar verrast door waren. En bunq reageerde met 'wij weten hoe het zit, die mensen klagen om het klagen'. Echt bizar hoe je kan reageren op zoiets...

Vandaag begint het ont-@bunq'eren. We vertrekken, tabee. Wat ooit begon als een prachtig idee werd een wereld van rekeninggluren, online intimidatie en vooral veel twijfel over de kwaliteit van hun directeur Ali Niknam. Dit was echt de druppel. tweakers.net/nieuws/229962/…

@SusanHy72604979 @LibertyCappy You know that lots of regulations were introduced to avoid acid rains. That is why certain gases and liquids cannot be used in refrigerators. Acid rain was not a hoax, we just fixed it.

The state of Florida would be under water due to global warming by 2000…taught to us in 1977 in a film we watched. I was in 2nd grade and living in Florida, so it scared me. They also told us we’d eventually have to stay indoors all of the time due to acid rain. The climate hoax is real.

@lukOlejnik If it is indeed based on retrieving a shard, then no homomorphic encryption is needed. The proper shard can be calculated offline. If they use something else, recovering the key due to a limited input set might be easy. So I'm still curious. 3/3

@lukOlejnik It appears they rely on sending back a shard instead of the whole database. But how is the shard identified? And how easy is it to reshard? Does anybody know? 2/2

Apple introduces homomorphic encryption via Swift. A cryptographic technique that enables computations to be done on encrypted data without revealing the underlying unencrypted data in th process. For example during cloud computations. In short, the building blocks of privacy-preserving technologies, techniques or protocols. But there's more! Private Information Retrieval protocols! This allows building a database and retrieving information in ways that is private: only the client knows what information has been requested. The databases does not know what information the client requested. Yet, the client gets the data. Why am I excited? I researched/used PIR ~15 years ago. In my Master's Thesis :-) swift.org/blog/announcin…

@bvgastel @Loran881 @TheNewOption_ @Austen @patriot_melissa @eastdakota It would be the exception if a state didn’t have audio recording laws so it’s a very safe assumption she’s violating state and/or her company’s recording laws. And it’s just shady on top of it to release audio of ppl w/o their permission.

Alright some very quick (assumptive) analysis: 1. Looks like the company was nuking most of the sales org. If they’re keeping <25% of an org the calculus isn’t, “Are they doing a good job and have we given them a fair shake?” It’s more, “Who are the top performers we need to keep? We have to get rid of everyone else.” Totally unfair to her. It may have been nigh impossible to reach the performance bar required to stay. But hard to say with no info. 2. The fact that it’s two HR people who don’t know her is either a big mistep or it implies her manager (and possibly her manager’s manager etc.) are gone too. 3. The HR team was probably given a big list of names they needed to tell, and probably had no clue as to why the decision making led to some staying and some going. That’s not a fun position to be in, but could be the only alternative to a mass firing in a giant Zoom meeting depending on how much of management was also fired. 4. It’s interesting that they’re so clear it’s performance-based and not a layoff. That’s not an accident. Could be to avoid regulations around the WARN act, or as justification to give zero severance. Usually in this call they go over the high level of that stuff, but this one took a turn. Sad across the board.

Getting fired is tough, but it’s important to handle it with dignity. Firing someone is also hard, requiring compassion and respect. Total disaster on both sides here.
