raincom··on Structuralism as a Philosophy of Mathematics
The problem is: do numbers exist? One group says, they don't. Another say, they do exist in the Platonic world, but this Platonic world is accessible from the world we inhabit in. Next time, look at the folks who looks for Platonic love:)
raincom··on AI assists clinicians in responding to patient messages at Stanford Medicine
Yes, that's how 'reputation laundering' works: just acquire all clinics and fool people with the tag "Stanford".
raincom··on Structuralism as a Philosophy of Mathematics
There are two kinds of mathematicians, or one can say, two cultures of mathematics: (a) problem solving, proving conjectures, etc (b) theories. Alexander Grothendieck belongs to (b). Paul Erdos to (a).

You can read Gower's paper on "The two cultures of Mathematics" at: https://www.dpmms.cam.ac.uk/~wtg10/2cultures.pdf

raincom··on Ask HN: What is the most useless project you have worked on?
When you are working with the same sales people multiple times, it is an instance of treated prisoners dilemma. Used car salesman is just one time prisoners dilemma.
raincom··on Apple layoffs affecting 700 workers, including Apple Car and Micro-LED teams
Apple laid off 200 workers in Apple Car division in 2019 too: https://www.sfchronicle.com/business/article/Apple-self-driv...
raincom··on Why Are Older Americans Drinking So Much?
Human flourishing works as long as it solely depends on the individual. However if flourishing depends on others, selfishness of others becomes the first priority. Question: is it possible to flourish without depending on others?
raincom··on Why Are Older Americans Drinking So Much?
Just because both X and Hitler say y, X doesn’t become a Nazi sympathizer. It is only possible if y is only derivable from the Nazi theory but not derivable from any other theory. Next time, when both X and Hitler are found to be said that Berlin is capital of Germany or that sum of three angles in a triangle is 180 degrees or that putting hands in hot water burns hands, start proclaiming that these claims are derivable from the Nazi theory or X is a Nazi sympathizer.
raincom··on The unreasonable effectiveness of VMs in hacker pedagogy
Default value is 300 seconds: https://developer.hashicorp.com/vagrant/docs/vagrantfile/mac...

So, just set config.vm.boot_timeout to 900 in the vagrant file, and see what happens.

raincom··on FTX's Sam Bankman-Fried Should Serve 40 to 50 Years in Prison, Prosecutors Say
The problem is proving the culpability of a particular individual, because it is the organizational structure that drives criminal acts. That's why big organizations have lawyers on their payrolls in order to provide policies to shield individuals. The only way to get around that is to use RICO. I don't think any US attorney wants to use RICO against any big business in the states, thanks to the revolving door.

raincom··on Nassim Taleb says the U.S. is in a ‘death spiral’ over government debt
MMT works well, if exporters want to swap their real assets (commodities, food, chips, metals, labor) with US dollars (nominal). No one wants to export their real stuff to Venezuela unless the latter pays in US dollars.
raincom··on The business of check cashing
For business accounts, "positive pay" and "reverse positive pay" are solutions to check fraud. With "positive pay", you upload the check number, the payee name, and the amount to your bank, if any of them don't match, such a check is rejected. With "reverse positive pay", your bank delegates the responsibility of approving any check to you.

Paper checks are useful, if you have various accounts with different banks. You can write a check for yourself to move money around.

Even mailing personal checks is not secure, as they are stolen. Even postal employees are involved in this [1].

raincom··on Apple and Goldman Sachs: A timeline of the messy partnership that will soon fall
Maybe, Apple and Goldman Sachs negotiated a better deal with Mastercard esp interchange fees. For instance, Costco pays Visa 0.4% interchange fees for accepting Visa cards exclusively at Costco.
raincom··on Quebec man who blamed wildfires on government pleads guilty to setting 14 fires
Poor farmers in India and other third world countries have noticed many phenomena since 1990: (a) unpredictable rain falls, because of which (b) people started to drill wells to fetch ground water, which was abundant at 100 ft. After drying up all ground water for 30 years, now one has to drill 700 ft deep to get drinking water, let alone water for agriculture. Also, population increase and demands for quality of life improvements are other factors. 100 years ago, many would have been happy with subsistence farming. 30 years ago, even poor farmers started to grow commercial crops (cotton, paddy, sunflower)--there is a shift away from subsistence.

Average people in 1990 would never have explained these effects using climate change. Now, average folks in the third world know more about climate change, global warming, droughts, intensity of and unpredictability of storms, depletion of aquifers, abuse of water usage, scarcity of drinking water, even human migrations due to droughts, etc.

raincom··on Indian workers see Israel jobs as 'opportunity of a lifetime' despite Gaza war
Trade unions in India are paper tigers, and have no influence on those who want to go to the Middle East for labor jobs. The genuine question: are conditions for Indian labor going to be worse in Israel than in the Arab countries?
raincom··on Harnessing heat from wastewater
How to deal with bad odors from sewage heat?
raincom··on Dynamic programming is not black magic
Demarcation problem is unique to Popper's philosophy of science. That problem doesn't exist in other philosophies of science. The best attack on psychoanalysis comes from the late philosopher of science Adolf Grunbaum's "The Foundations of Psychoanalysis: A philosophical critique"
raincom··on Bill Ackman's academic wife Neri Oxman's dissertation is marred by plagiarism
Love to see Ackman's project of going after all academics at MIT for any instances of plagiarism. Usually fights between different groups of elites show what's going on.
raincom··on Short sellers lost more betting against Tesla than any other company last year
One should never short a stock based on fundamentals. That’s an expensive lesson every stock trader would learn after incurring losses.
raincom··on A 1690s Peanut is Reborn
Indian grocery stores carry both small peanuts (Indian variety) and large peanuts (American variety). 4 lbs small peanuts cost about $5.99; 4 lbs large ones cost about $6.99
raincom··on Amazon's Silent Sacking
What you cite is one factor. Another factor is access for students. Once upon a time, curious students had two choices: buy books to learn on their own; or go to whatever low quality teachers they had. Cheap internet, YouTube, LibGen, other resources help students as long as the latter desire to learn.
raincom··on Amazon's Silent Sacking
Candidates can promise many things, but they won't pass laws to ban outsourcing. Even if they do, they dilute it to an extent that these laws become impotent by creative loopholes.
raincom··on Operation Triangulation: What you get when attack iPhones of researchers
S-box is used in symmetric ciphers in cryptography. S-box = substitution box or lookup table [3][4]. You can see an example of Rijndael s-box in a python script here [1][2].

raincom··on Are EU banks just mass surveillance devices?
Governments indirectly forces banks to not deal with physical cash any more. If you frequently deposits/withdraws cash or any untraceable monetary instruments, AML algos flag your account as risky, leading to closure of your bank account. Even though your politicians say that they are not waging a war against cash, governments through regulation/laws such as BSA, AML, and KYC wants a cash-free world, as it becomes easy to trace every transaction.
raincom··on With 1 Sentence, Patagonia Just Gave a Masterclass on How to Treat Your People
I think Apple gives all days off between Christmas and New Year. That's for employees, but not for contractors.
raincom··on Ask HN: Stories of political intrigue in large companies
Besides all good references you see here, try to understand human beings as selfish creatures. Cooperation comes into being when you need to play with the same person/team many more times, that is, iterative games. If other party, say, X just works with you for one time, X can use you and dump you, while being nice at the same time. However, if you and X are forced to work together many more times: X and you have to cooperate.

It is easier to backstab than being openly inimical. Being openly inimical has both emotional and political costs; backstabbing is easy.

raincom··on Today Is One of the Biggest Surveillance Votes. Will the FBI Stop Spying?
That’s how every response to this sort of criticism: when people criticize capitalism, response is “that’s not a true capitalism”. When people criticize policies of communist regimes, defenders of communism say that these regimes are not instances of real communism. When majority instances are not supposedly true instances of whatever-is-in-dispute, then one should stop coming up with it-is-not-true-X.
raincom··on Today Is One of the Biggest Surveillance Votes. Will the FBI Stop Spying?
Because of metrics, easy tasks in scrum/agile are transformed into monstrous little tasks, spanning five months. Same thing with law enforcement: they find some mentally deranged person in KS, lays a trap to ensnare him in terrorism charges. Yes, 'our dragnet' captured this many number of terrorists (that is, y).
raincom··on Today Is One of the Biggest Surveillance Votes. Will the FBI Stop Spying?
FBI director in his exchange with Senator Lee [1] claims this : the case law shows that 702 doesn't violate 4A. However, Sen Lee retorts back with 'FISA court doesn't even given standing to people who wants to litigate this'. So, Secret courts, lack of standing is what the relevant case law boils down to: if people are not permitted to litigate, no case law is established or challenged.
