inasio··on Two men got jobs at Amazon just to steal copies of Zelda
Reminds me of the South Park episode where Cartman cannot wait any longer for the (Nintendo Wii?) to be released, goes and freezes himself in a glacier. Nowadays he could just get a job at an Amazon warehouse, win win
inasio··on Apple’s new headset meets reality
Just lean into the nausea thing and make a very nice sailing simulator, I'm sure Larry Ellison would sponsor as long as there are F50 cats.

(0) Not sure if this is going to change immediately after release

inasio··on The Legend of Zelda: Tears of the Kingdom Release
The world feels almost real, every hill, wall or tree is climbable, every crevice has something interesting, if you just swing your sword in a field you'll cut grass and lizards will pop out. It's hard to try to go on a mission and not get lost going after something cool that you find along the way.
inasio··on MemComputing vs. Quantum Computing
Their tagline at the end:

```MemComputing is available today and is delivering the performance expected of quantum computers across a wide range of valuable optimization problems in industry. ```

Quantum computers unfortunately are not expected to do well against traditional OR algorithms in most (all?) OR problems (Grover search only helps in brute force search; Shor it not quite an OR application, and relies on quantum effects), so not really a strong selling point in my view

inasio··on MemComputing vs. Quantum Computing
These guys claimed that they could factor semi-primes in polynomial time [0], essentially P == NP. Scott Aaronson predictably had some thoughts on that [1]

inasio··on Basic Physics of Rowing (2007)
I tried to find similar distances to compare, but it might have been better like you suggested to compare around similar times. One other thing is that the conditions in an indoor velodrome are pretty ideal vs being in the water, although you also can get currents and wind (although records cannot be certified unless winds are below some threshold I believe)
inasio··on Basic Physics of Rowing (2007)
One cool fact is that rowing offers a bigger efficiency advantage over swimming than biking over running:

The efficiency advantage of biking versus running is around 2.66x, the hour record on bikes is currently 56 km (56km/hr), and the fastest marathon run is around 21km/hr.

On rowing vs swimming, the current freestyle 1500m record is 14:31 (6.2km/hr), whereas the best time for single scullers is 2km in 6:30 (18.5km/hr), for an advantage of around 3x.

* I tried to pick roughly similar distances to compare.

inasio··on The unintentional dystopian beauty of oil rigs
At a local coffee shop they had paintings for sale of stormy ocean scenes with oil rigs in the mist. I still regret not buying one (it was pretty reasonably priced)
inasio··on CATL has announced a new “condensed” battery with 500 Wh/kg
Ridiculously higher. One gram of matter converted to energy (matter-antimatter annihilation assumed to be 100% efficient) yields, using E = mc^2 and 3.6x10^6 Joules per Kilowatt-hour, 25 million Kilowatt-hours
inasio··on MRI brain images become 64M times sharper
If you have a major issue, say a tumor, MRI is great, but for smaller things I agree with you that a single image is not great for a quantitative assessment. What does have a lot of value is when you have a baseline image and you perform yearly scans that are compared against each other (similar to how carotid ultrasounds are used for cholesterol assessment)
inasio··on MRI brain images become 64M times sharper
Not that cheap for Mexican people, median salary is $600 USD/month

Public healthcare. It's free for everybody (with a Canadian healthcare card), but resources are limited.
inasio··on MRI brain images become 64M times sharper
In my opinion [0] a much more interesting track to pursue than super high-T scans that only work on mice (dead mice at that) is low field MRI scanning. MRI is amazing, but incredibly bulky and slow. In Canada you have to live for 6 months with a knee injury before surgery just because of the wait to access an MRI. Companies like Hyperfine (not affiliated) and Deepspin (just learned of them) make low power portable machines (I believe NFL teams were early costumers).

A single MRI image is not super helpful, still more art than science, the real benefit comes from having periodic scans against a baseline. Boutique health clinics offer yearly scans to high net-worth individuals, rolling this out to a larger population could have a huge impact.

[0] educated opinion, I also collaborated on a PNAS MRI paper

inasio··on Ask HN: Is "The Art of Computer Programming" worth investing in?
I recently had to work on SAT problems (and SAT solvers), the relatively recent material he wrote on them (section 7.2.2.2, close to 300 pages!) has been amazing, I sometimes just open a random section and go through it, super readable and informative. I'd highly recommend it, especially if you can have direct use of it.
inasio··on The Complete Guide to All the Taquerias of Redwood City, v2.0 (2008)
Awesome page, but what the hell, no pork is a hard constraint, lots of awesome pork tacos (cochinta, carnitas, suadero, chicharron...).

One subtlety about Mexican tacos that is lost in other countries is that there are different taco types for different times of the day. Lamb barbacoa tacos (not to be confused with Jalisco-style beef barbacoa), pork carnitas and chicharon are definitely morning/lunch, whereas pastor and suadero tacos are more an evening taco. Northern style beef tacos, and Yucatan-style cochinita are more for lunch (Mexican lunch is the main meal, often around 2-3pm)

You probably owe him around $950 as there are a couple of kets in there, but mostly pretty clean I'd say

inasio··on Illustrations of Japan’s “unseen” workforce of trains that work at night (2019)
Spoon and Tamago is probably the newsletter I've been subscribed to the longest, every single (infrequent) email is beautifully crafted with very nice content, highly recommend.
inasio··on An Open-Source Espresso
I know this is how many people do it, it strikes me as surprising that you don't need this compromise at the very low end (Breville Bambino), nor at the high end (Decent), but there's nothing in between
inasio··on An Open-Source Espresso
I've been meaning to upgrade from a Breville Bambino, but key for me is a machine I can turn on and brew coffee right away on a whim (small footprint would also be nice), but I haven't found any options between the Brevilles and the Decent.
inasio··on Which city builds skyscrapers the fastest?
The other way around, to me this means that the total floor space is the size of a 66 meter square, which is ridiculously small. I think it must have been at least 1000X times that
inasio··on Which city builds skyscrapers the fastest?
The numbers don't make sense to me. LA at the top at around 445,000 sqft per year is equivalent to a gross floor area given by a square of sides 667 feet, or ~66 meters. It's probably off by like three orders of magnitude
inasio··on Thomas Midgley Jr. invented leaded gasoline and chlorofluorocarbons
Not so one-sided, Fritz Haber [0] is another very interesting chemist. Got a Nobel prize for the process to synthesize ammonia (modern fertilizer production), but then also got side tracked with the 1st world war and became the father of chemical warfare

inasio··on DDRamDisk: RAM disk, a disk based on RAM memory chips
Are you talking about Optane/3D-XPoint? The physics behind it seemed insane to me, amazing that they got it to work. I heard that the NVME protocol was originally designed with it in mind
inasio··on Samsung's response on 'moonshot' controversy
I wonder if Samsung phones do the same "upscaling" on popular landmarks, the Eiffel tower, Grand Canyon, etc. I'd give it better than even odds
inasio··on Was there a tech-hiring bubble? Job postings data suggest so
Fuck all (i.e. nothing at all), maybe?
inasio··on Apple and Foxconn win permission for 12-hour shifts for women in India
A lot of hospitals (and Tesla plants) have four 12 hour days, then 3 days off (the next batch switches to nights though). Works neatly to around 40 hour weeks, but very hard to match to school schedules, plus switching days and nights weekly is tough.
inasio··on Amazon pauses construction on second HQ in Virginia amid job cuts
MEC, which used to be Canada's equivalent of REI, went bankrupt a couple of years ago (the C used to be co-op, currently stands for company after they got rescued by a fund). Talking with a long-time employee, a big reason was ~100M spent on big fancy headquarters (new owners promptly sold them to EA)
inasio··on Nordstrom to close all 13 stores in Canada, lay off 2,500 workers by June
The Vancouver store is prime real-estate, overlooking the Art Gallery, Microsoft has two very nice floors just above them, and a few other tech companies have offices below.
inasio··on Nordstrom to close all 13 stores in Canada, lay off 2,500 workers by June
There was an interesting fight at the time over the Target trademark, someone noticed that there was a Canadian trademark for Target up for grabs from a failed company and bought it, anticipating Target coming into Canada. Target ended up settling in court [0]
