swimfar··on Two more restaurants in Toronto just got rid of tipping
In addition, the amount a waiter is tipped is also often influenced by their race, sex, and physical appearance.
swimfar··on Show HN: Dungeon Map Doodler – Free online map drawing tool
I like how clear, and easy it is to try it out. Big "DOODLE NOW" button right in the middle of the landing page. In two clicks I've already created a (tiny) dungeon.
swimfar··on Death Valley soars to 130 degrees, Earth’s highest temperature since 1931
"The standard measuring conditions for temperature are in the air, 1.5 metres (5 ft) above the ground, and shielded from direct sunlight intensity" [1]

Lots of people claim that their region/country has had hotter weather than the records, but I doubt the temperatures were taken in these more precise conditions. It's not like there aren't scientists and meteorologists all over the world (including Africa) who are measuring these things constantly.

If you're standing on dark surface in a hot place, the air temperature can be much higher. "In recent years a ground temperature of 84 °C (183.2 °F) has been recorded in Port Sudan, Sudan."

swimfar··on Feds say Yale discriminates against Asian, white applicants
But what percentage of college students are black? (sincere question, couldn't find the answer from a quick search). Without knowing that I don't think it's fair to say they aren't doing a great job. Just because other colleges are doing better, doesn't mean Yale is doing bad.

edit: This report says 14% of college enrolled U.S. residents were black in 2017. But that makes it sound like it doesn't include international students.

swimfar··on TSA considers new system for flyers without ID
I got stuck on the non-downtown side of Shanghai once because I assumed that I'd be able to walk or bike across at least one of the bridges. But I couldn't find any way to get across. I had to wander around until the metro opened back up in the morning to get back across (and make it to flight in time).
swimfar··on On-Device Supermarket Product Recognition
I would love something like this paired with augmented reality to show/hide/highlight only the products that meet my search criteria. Try going to a big supermarket to look for whole-milk yogurt, for example. It's a pain trying to filter them out of the rest of the 100 varieties.

Another thing I would like to do is compare products by price/quanity. Maybe I'm trying to get the most protein/$, or oz/$, etc. You could also hook it into some database to only show you ethically caught fish, organic projects, fair trade products, local products, etc.

I've thought about this kind of technology a lot. Cool to see that it's actually becoming possible.

swimfar··on Unlearn rotation matrices as rotations
I find that sometimes even when I'm familiar with a topic, it ends up being a bad reference. This is especially true when they start introducing variables and constants that haven't even been defined.
swimfar··on Inside A £30 Record Player
Even a lot of relatively cheap record players have adjutable tonearm weights. But it's not just the vertical needle force that wears out the records. The other issue is lack of adjustable (or any) anti-skate force. This keeps the needle from being forced to one side of the groove.

I stumbled across the article recently where someone set up an A/B test to try to observe record damage from these cheap turntables. While there are some limitations of the experiment, I thought it was a good idea. There are too many "facts" that are just accepted as true without any emperical observation (not just in the audio community).

swimfar··on Google removes all Danish music from YouTube
It's best to just assume that all acronyms are obscure and spell them out the first time you use them, especially ones related to a specific field of interest, hobby, profession, or culture.
swimfar··on Is your chip card secure? Much depends on where you bank
Early on the customers were completely liable because the banks claimed that the only wait a fradulent charge could be made is if the customer "allowed" their PIN to get stolen. Eventaully they changed this and made it more customer friendly.
swimfar··on Is your chip card secure? Much depends on where you bank
Because many consumers don't see chip and pin as an upgrade (though contactless is nice). So it depends on the banks to decide whether it's worth it. With debit cards, the extra security is valuable. But with credit cards it isn't really too important to me because I can just reverse fraudulant charges.

As for the experience of using each, it seems to depend a lot on the machines. I did not like using chip and pin in Europe because it seemed to take longer and required more interactions. With the magstrip I pull the card out, swipe it, put it away. I'm never waiting for anything. Sometimes I'd have to swipe it twice, but that didn't happen too often to me. But it seems like different people have very different experiences with these things.

edit: this mostly applies to credit cards, which are much more common in the US than in Europe. But the lack of significant benefit for credit cards to use this technology could have resulted in momentum that slowed the adoptation of it for debit cards.

swimfar··on Universal Basic Income is Capitalism 2.0
"But for every you, there's a me"

Everyone agrees that there will be people who will want to work, and people who won't. The question is what is the ratio, and is it enough. No one can predict this with a high level of certainty. We all just have "a feeling", which coincidentally happens to align perfectly with whether or not we believe in UBI.

swimfar··on Why do U.S. coins seem to be in short supply?
I've heard that some banks will no longer take large amounts of change from people. I'm not sure if they got rid of the change counting machines, or just don't want to deal with it. This could have some effect on the amount of change in circulation. People then have jars/ashtrays/drawers of change that they can't easily put back into supply.
swimfar··on Dixie cups became the breakout startup of the 1918 pandemic
I'm not sure why people don't like your comment. It's the most likely answer to the previous poster's question.
swimfar··on Dixie cups became the breakout startup of the 1918 pandemic
OP never said they were named after the South. Just implied that having the same name could still be a problem. Github master branches have nothing to do with slavery but they still got rid of the term to avoid any possible connections one may make.
swimfar··on Drug cartel ‘narco-antennas’ make life dangerous for Mexico’s repairmen
No. Not even marijuana is legal in Sweden.

"The drug policy of Sweden is based on zero tolerance focusing on prevention, treatment, and control, aiming to reduce both the supply of and demand for illegal drugs."

swimfar··on Porsche found a way to 3D-print lightweight pistons that add more horsepower
I don't understand the point of this comment. No one is saying that 3D printing will make forging obsolete. There's always a balance of trade offs. It's up to the designer/engineer to decide how something should be made. Developing more options, and better understanding those options is part of engineering progress. It may be good to temper expectations (no pun intended) to avoid overhype, but at the same time I think it's also good to let people's imaginations run wild because that's where creative developments come from.

For example, I'm sure people will come up with ways to have more control over grain boundary and other material properties of the 3D printed material through the use of heated chambers, annealing, new alloys created for specific processes, etc.

swimfar··on Porsche found a way to 3D-print lightweight pistons that add more horsepower
For some types of 3d printing where the material is laid down in a bead, the path of the nozzle has an effect on the resulting part. So having a wide row of nozzles would give you less flexibility in the design. But this may have less of an effect on certain metal 3d printing technologies. For example, that could work very well for some metal sintering methods.

https://en.wikipedia.org/wiki/Selective_laser_sintering

What I find facinating about 3d printing is how much unexplored area of research there is. Not only is there so much more to explore, a lot of it is very accessable without lots of money or technology. This is especially true on the sofware/gcode/slicing side of things.

swimfar··on Target’s gig workers will strike to protest switch to algorithmic pay model
Probably just because it's much much simpler. How do you objectively compare the delivery difficulty of 100 lbs of potatoes vs a diamond ring? Should the delivery cost of 100 lbs of diamond rings be the same as 100 lbs of potatoes? What about 100, 1-lb boxes vs 1, 100 lb box? Size also makes a difference. You could charge per item, based on weight, like postal shipments. But then you also need to have accurate weights and dimensions. And transporting two boxes to the same address isn't twice as difficult as shipping one box. These aren't insurmountable problems, but as long as most people aren't complaining, there's little pressure to change.

edit: changed shipping to delivery, to avoid confusion.

swimfar··on Cheddar empire: Rise of a cheese superpower
That was just the first link I found, and it was just for the first category. Other (non-US based) competitions also have winning cheeses from the US. My point was only that there are certainly good cheeses from the US. Of course, it's all subjective, so it doesn't mean that any one person will be able to find a favorite cheese from there.

swimfar··on Cheddar empire: Rise of a cheese superpower
There are plenty of American cheeses that win the top prize in international competitions. Six of the eight cheddar categories at the following competition were won by US cheeses.

swimfar··on Eastern European Movies
It took me a bit to figure out what I was watching. It's a comparison between scenes from "The Revenant" and scenes from various films directed by Andrei Tarkovsky.

swimfar··on International Standard Paper Sizes
Almost the entire world still uses nautical miles, knots (speed), and feet for aircraft altitude. I'm pretty sure most airplanes all use AN hydraulic fittings, which are based on Imperial sizes (correct me if I'm wrong there).

Also, people always say that the US is the only country that uses feet, pounds, miles, etc. But there are a lot of other countries that still use those units, or at least understand them, even if it's not an official unit. I even work with engineers from China who use and understand Imperial units. I also visited a friend in Ireland who had a (pre-digital) scale that measured weight in stones.

swimfar··on Revenge of the Suburbs
I agree that having a house downtown is a nice way to live. And there are plenty of great cities in the US where houses close to downtown are affordable to the middle class. But a small, semi-detached house doesn't sound like medium density to me. That's only an option in a city where not everyone wants to live downtown (areas where people prefer the suburbs), or if you have enough money to outbid everyone else who wants that house.
swimfar··on Cleaning My MacBook After 16800 Hours of Use
It's not a fact of life, it's due to poorly made screwdrivers/bits. Unfortunately, it's getting more difficult to find, or at least be certain of the quality of tools. You can only really know that it's a good tool after getting a lot of use out of it. But by then that particular tool may no longer be sold, or it may not be manufactured the same way, or even in the same factory. So any verified reviews may be out of date.
