contubernio··on Over 5,200 Ebola cases recorded in Congo
People on the street, so to speak, don't know better even in advanced nations with strong educational systems. Look how much rejection of vaccination there is in spite of "knowing better". In many African nations there is very reasonable suspicion of European authorities - as there is a long history of abuse and degradation that has moreover been weaponized politically kn the post colonial era. The solution is trustworthy and pedagogical people on the ground doing a lot of hard work and that requires lots of institutional support.
contubernio··on Linear algebra done right
Overrated and tendentious book. There are many better linear algebra texts. His polemic against determinants is poorly motivated, misguided, and distracting. The writing is quite formal and not terribly inspiring. The coverage is adequate but nothing more.
contubernio··on Abdominal fat predicts heart disease risk better than BMI
Another common misconception is that one is still healthy with high BMI that comes from having lots of muscle. It's not clear that lots of muscle is healthy.
contubernio··on What sort of maths are LLMs good at?
People with lots of knowledge and (monetary and computing) resources.
contubernio··on France to ban unsolicited telemarketing calls
My own bank in Spain calls me constantly cold from landlines.
contubernio··on France to ban unsolicited telemarketing calls
In Spain I have recently been getting far more robo scam calls. New several a week.
contubernio··on I was accused of using AI in my dissertation but I wrote it all myself
My butcher is still bitter because forty years ago he studied very hard and passed latin but the teacher accused him of cheating and failed him in the grounds that a loutish thuggish kid like him couldn't possibly have studied that hard or learned latin. He still tells the story and still gets very angry while telling it.

These kinds of things do enormous damage to people.

contubernio··on Half of Europe's towns and villages have fewer residents than 60 years ago
1. The phenomenon exists, but what is the problem?

2. Surely "municipality" does not mean the same thing in different countries.

contubernio··on AI Fortunes Are Reviving an Old Debate About Private Power
Philanthropy reflects a failure of the state to realize it's most basic functions.
contubernio··on Taxi drivers rarely die of Alzheimer's
This is a case where the claim is clearly nonsense, and the interesting question is where is the error.
contubernio··on Why some people mow a lawn better than others
There are a number of bad premises in this article.

For example, most people in the world (outside the USA in particular) have never mowed a lawn. I live in a city of 3.5 million and essentially no one has a lawn.

When you really mow a lawn terrain matters. Most lawns are not flat. One goes on lines of equal height not up and down a hill.

Edges are different than the interior part of the lawn, particularly if they abut flower beds, curbs, etc.

Re passing a given spot is sometimes an efficient way to mow it properly. Particularly in dead ends and odd corners. Etc.

contubernio··on NSF pilots 4-year PhDs with industry research placements
Europe has already pushed shorter PhDs with the excuse of facilitating development in technology/industry. It's been a huge failure in mathematics for various reasons among which are: 1. Students don't have time to develop autonomy and independence, so this remains for the postdoctoral period. 2. Students are forced into publishing things that shouldn't be published (it's often a requirement to terminate a doctorate) and these are shallower and less complete than they should be.

The true motivation seems to be that it is cheaper to fund 3 years than 5. Master's degrees have been made obligatory prior to doctorates (in the US this is traditionally not the case) and so are not covered by doctoral funding - rather they are paid for by students in many cases.

It may very well have sense to have a shorter track aimed at industry, but it shouldn't be called a doctorate and all doctorates shouldn't be shunted into this setup.

contubernio··on Clinical failure rates over the decades: yikes
Without doing any serious thought, it is concerning that the statistic doesn't vary more temporally. It seems too consistent, and raises the suspicion that it reflects regulatory agenda more than anything intrinsic
contubernio··on Show HN: I mapped every US golf course
In the USA as elsewhere golf courses are incredible wastes of water and false green spaces that would function better as green spaces were they actually parks open to the public they serve the wealthy. What is different is that in the US there is very little real (operational) worry about waste of water (or other resources) - at least compared to other places - and there is lots of space compared to other places.
contubernio··on Why American ambulance rides are so expensive
Sharing costs generates institutional incentives to keep costs down. Individualizing costs generates institutional incentives to charge more.

Perverse incentives are the essence of what is wrong with US medical systems.

contubernio··on The glass backbone: Why the Army's logistics will break in the next war
It could be attacked easily via an alliance with Mexico or Canada. The premise that such a thing could never happen is not a good one for military planning.
contubernio··on Microsoft Can Track Users via a Windows Device ID
Does this not violate European privacy laws?
contubernio··on French physicist and media star loses doctorate after plagiarism investigation
The anecdote is meant to illustrate not to substitute a full data set.

Universities and other similar large institutions usually err systematically in one direction - that which protects the institution.

contubernio··on How Madrid built its metro cheaply (2024)
No one lives in rooms. Everyone in Madrid lives in apartment.

The average salary refers to those who have a job. Most family units have some that don't.

contubernio··on I told them forced consent was unlawful. 5 years later it cost Elkjop €1.8M
Alternative approximate translation: while I urinate on you tell me it's raining.
contubernio··on How Madrid built its metro cheaply (2024)
In Madrid where the average monthly pretax salary is below 1500 a shared room with four strangers costs 400-709 a month and small aprtments in bad neighborhoods cost 3000-4000 a square meter to buy.
contubernio··on How Madrid built its metro cheaply (2024)
False. I live in Madrid and being near a metro station a. Has no issues (for almost all stations) and b. is considered highly desirable. 10 minute walk is considered a lot (mine is 5, to either of the two nearby stations - at 10-12 minutes I can walk to four stations). These are genuine underground metro. They're deep and vibrations are mostly not an issue.

The article paints a somewhat biased view of the construction process. It gives too much credit to Gallardo and the pp and conveniently ignored the serious issues in the sam Fernando de Henares área created by too rapid construction that ignored environmental and design issues in the Sandy soil near the Jarama river. Several hundred apartments have been condemned because of it and a whole neighborhood affected ...

But it is the best metro I've seen in Europe or north america. Most usable and cheapest to use.

contubernio··on French physicist and media star loses doctorate after plagiarism investigation
The very few cases that result in sanctions are generally horrendously flagrant.

With another professor I caught a flagrant case in a student thesis and we faced attacks from the university administration because the student had a stellar transcript (also not the positive signal some might think). Punishment was almost inexistent.

It's difficult for me to imagine what it would take to get a doctoral thesis revoked.

contubernio··on French physicist and media star loses doctorate after plagiarism investigation
Rephrasing is worse than literal copying from a procedural point of view because it demonstrates intent and obviates a defense of mere incompetence.
contubernio··on U.S. to dismantle system tracking Atlantic currents that are at risk of collapse
A time honored practice of dysfunctional institutions when confronted with a problem is to stop paying any attention to it. Problem gone. It's one of the derivatives of quality control.
contubernio··on Failing grades soar with AI usage, dwindling math skills in Berkeley CS classes
Professors suddenly realized everyone was cheating and started paying attention, but the cheating isn't new ... A lot of faculty are happy when their students get good grades because they interpret it as I'm such a good teacher instead of I should pay more attention to how they cheat. AI woke some of them up to reality.
contubernio··on Meta launches Instagram, Facebook, and WhatsApp subscriptions
Absolutely inaccurate. I am nationalized Spaniard living here 2+ decades. Almost no one over 50 calls on the phone and when they do they almost always send a message first. The large public institution I work in is removing landlines completely because they get too little use to justify the cost.

I am (mostly against my will) in multiple professional and personal Whatsapp groups. Use is constant and daily and unavoidable. It is the principal means of communication in both work and personal settings. Calls are always a second option.

I suspect your experience reflects only partial integration in local culture.

contubernio··on Meta launches Instagram, Facebook, and WhatsApp subscriptions
In Spain whatsapp is universal and necessary for everything personal and professional.

Some hard core committed communists prefer telegram, but even they usually have to have whatsapp too. No one uses signal or even knows what it is.

contubernio··on What if remote working, not AI, is to blame for weak junior hiring?
Most comments are just older commenters confirming what everyone over 50 knows, which is that young people are slow and stupid and not as competent as we were back then nor as competent as we are now.

Every generation ever has known this once it got old enough ...

contubernio··on United Airlines 767 returns to Newark after Bluetooth name sparks alert
It's as recent as WWII was when Nixon got elected.
