Complaining about externalities of PoW cryptocurrencies is like complaining about the fastest function that exists in your code and is magnitudes more efficient than anything else. Externalities that pollute the ocean, air, rivers and citie

I do not know where they found the information to conclude there are no math based guarantees. The initial version of Monero had a flaw but if you start transacting now I do not believe anyone can deanonymize wallet ids or amounts. Even if

The only way ads can work today is that the ad system takes the metric from the user. If someone is tweaking the keywords and other things on their own the ads will very quickly stop working.

Yeah, I guess. I assumed black means completely invisible and unpredictable (do not know what will happen and when), white means we know it can happen but just don't know when exactly will it happen.

It's quite easy to see a pattern. Same pattern appeared for Cowspiracy [0] and a similar one for The Game Changers [1]. The same pattern can be seen with regards to pandemic warnings before this one. There's a very strong tendency

I have, fully remote consulting is beautiful. They hand you over into a giant and one gets lost forever. I'm also aware some of my college friends have similar engagements. It gets to a point where you feel a bit bad for not doing much

Get a job at a consultant company that hands you out to others as an expert. It will take a while for the big corp that received you to figure out that team members are doing all the work and that you're applying low effort on everythi

Given that all of the code uses React.FC instead of React.PureComponent or regular React.Component the efficiency obviously lacks, there's no props diffing and everything will be rerendered.

Dependency injection frameworks are solutions that no one needs to solve their problem. It appears everywhere because everyone knows about the solution.

Sounds like they just aren't innovating. The degree to which they have solved the issue obviously isn't enough.

Why isn't Deliveroo innovating so much on the technical side that the gas/delivery time savings aren't making everyone satisfied? By now, they should have enough data to know who's going to order from where and using the

Nothing came close to the Foobar conversion interface. I didn't have to bother with splitting album flac files, tagging, picking v0/v2/v3, everything just a click away once it's inside Foobar. I've been using Flacon

OR really messes things up. UNION instead makes things fast.

Current best heuristics, Lin-Kernighan-Helsgaun arrive probabilistically at better percentages for TSP. Definitely makes you wonder if P = NP is even relevant when all the interesting instances can be solved to optimality or very near to it

Google Scholar has a bunch of papers, from Oregon to Netherlands and papers analyze individual cases, categorize illness, history of suicide attempts etc.

Sounds like reasoning out of emotion instead of data. I'd have these fears if countries that already have assisted suicide report that most cases are healthy elderly people deciding to not live anymore. What all the data says is that m

Any dynamic programming algorithm where n-th item depends on contiguous k ones with some nice binary operation (like +) can benefit from storing the state in a segment tree, so when you go and calculate n-th item, you can get the value in

A nice comparison. So for Bitcoin we acknowledge the fixed gain but for our planet the gain is limitless, steaks, cars, and heating.

The whole point of a model is to take advantage of data with more information. If GPT-3 output sucks for predicting human output then it will be ignored by the model during descent. Otherwise the learning algorithm is defective.

Environmental issues. Same reasons I guess why Bitcoin is disliked. But most Bitcoin dislikers still drive a car, are careless with heating and cooling and eat steak at least once a day.
