Everything can be political, and ideas can always have political consequences and the people that advance them always have political persuasions. But the arena of academia is that of logic and reason, not of political convictions. So even if everything has a political connotation, the whole point of science and academia is to try to keep that out of the way, and use cold reasoning instead. A protest can show that you don't accept an idea, not that an idea is not worth being accepted.
Add a little song and dance around the narrative.

It's ridiculous how well I can still remember many of the kids' songs and poems, even though I have little recollection of anything else left from that time.
I also rode this kind of bike once as a kid on a fair. Same thing, the reflex was to strong and familiar to consciously override it. I had a similar experience like this when I wanted to learn snowboarding, I tried to do it myself without lessons. Learning to stand, slide (front and back) and break on a board was 'easy'. But I was taking to long teaching myself to turn a slide into a slalom properly. Turned out my reflex to break was to strong and I had to force myself to unlearn this reflex.
Not if one is lucky enough to live close enough to the city center.

From my experience in Lisbon, it took me 1h to do 30 km during rush hour and 2h outside rush hour.

Ah, and good luck returning back home after mid-night.

Talking with Spanish friends, their view of Madrid network isn't much different from my experience.

In any case I was talking in general, because outside the major European cities, the transports are even worse, like 1 bus connection every two hours until 8pm and such.
I was on a site the other day, which I won't share publicly, that required "NO MORE than 6 characters, including precisely 1 number and 1 capital" (paraphrase, my emphasis) ... I definitely WTF-ed at that.

My default is 20 characters of alphanum, or 16 of "graph" (though I drop look alike characters; 32 chars if I'm entering payment details).

One has to hope they have a small limit on retries. They definitely carry commercially sensitive data and do payment processing.

What worries me is they used js to catch my attempt to use 20 chars, so they're not operating completely naively -- all I can think was it was a misinterpretation and s/most/least.

I'm partial to Gerrit if you're looking for a git native solution with branch, draft, patch, review, iterate workflows with proper merge/rebase handling.

It is a bit different from "GitHub flow" but mostly a big improvement in an organisation context (vs FOSS.)

Media wiki has the best docs but it's a bit dense.

https://mediawiki.org/wiki/Gerrit

This page below has a decent graphic and lots of quick examples to show you how powerful it is to work with git instead of gimping it with a wrapper.

that is why you put your database behind a firewall and not expose its port to the public internet. There is really no need except for a handful of really edge cases where you have to expose the port to the internet even then you can limit the access to specific hosts only.

It's an ok test, probably some of those are more "googlable" than just having it in memory.

(I find funny the "love for metaclasses" that people consider as "advanced Python" - it has its use cases, but it is a bit restricted. Also DO NOT USE ABC - it's one of those "let's take this Java thing and try to fit it" but it manages to be an even weirder transplant than logging)

A database that lists the officers responsible for force by name, frequency and race. Resulting in neat graphs that strongly suggests that police violence is caused by two factors: individuals and/or race.

Police brutality is a serious problem and data like this should be available, but several things here are (maybe intentionally) provocative:

1. Listing the officers by name is a kind of online vigilantism that ultimately might threaten their personal safety. It doesn't sit well with me at least. This data should be anonymized.

2. The prominence of graphs that conflict race of officer with race distribution of the community. Race should really be stripped from this kind statistic. Race is a social construct based on superficial attributes that does not carry any explanatory meaning. It mostly serves to underpin racist prejudice, which in turn serves to blur out the real reasons for a problem.

Evolution is not a directed process. It is essentially a load of small random mutations, and the random evolutions that improve the organism's fitness get passed on.

So, yeah octopodes are really cool, but it's not correct to say that octopodes evolves intelligence and chromo-camouflage in some sort of direct way because they needed to become intelligent: what would have happened was over a very long time, certain families or society started being born with more than above intelligence, which allowed them to get better access to food and mates, which meant they were fitter, which meant they may pass on their advantageous traits their children, who would carry it on the their children etc.

Evolution doesn't happen "because" of something. Wales didn't evolve into marine mammals because they needed more food. Yes, they needed more food but their evolution just randomly moved their species towards the water.

For example a terrestrial wale may have been born with the ability to hold its breath, just by chance. Eventually every terrestrial wale has inherited that ability, and then the process repeats, with another mutant wale evolving thicker blubber which would allow it to obtain more food, spend longer in the water end pass on their trait for blubber.

>I would seriously expect most beginners to have some idea about modulus, but next to no idea about key features.

As someone who began learning with Python, I knew many key features before learning modulus, and I don’t think I have even used modulus in a project yet.

>For general questions, I like things like "What are the key features of the language?" but I phrase them as "What are your favorite parts of the language? Least favorite parts?"

And, picking up where I just left off, this change in phrasing would have made a world of difference at the time haha.
Gitlab seems to fit all the Open Source Project ideals and philosophy. They don't want the burden of managing a dozen difference software or services for their development, they want coding, not time messing with Ops. And it has to be Open Source and no lock it. And Gitlab could even host it for you with with out you having the hassle.

Amazon, Google. One of them likely to acquire Gitlab. Strategically speaking both company would be a great fit for Gitlab, the only problem is both company absolutely loathe Ruby and Rails.

Or there could be another slim possibility, Microsoft decide to Open Source Github Core.

IME "knows what metaclasses are" is intermediate knowledge while "knowing in which very rare situations use them and when to avoid them at all costs" is more advanced knowledge.

I've seen it enough that I almost consider it a rite of passage for intermediate developers to "discover" an advanced feature like metaclasses and then use them inappropriately to prove their chops, creating an almighty mess in the process.
The plan to move the Swedish town of Kiruna
I have no idea why we're talking about it in a medical setting when this is clearly meant to show how dangerous it is in the hands of the public. Fentanyl is dangerous on the streets and safer in the hospital sheets, of course, but that basically has no bearing on how it's used by addicts and cartels.
I absolutely agree. From my experience this is also true for the best professional mathematicians, it seems that generally they have picked a very large toolbox of memorized "tricks" that they can effectively (and intuitively) apply, rather than approaching every problem as if it were an entirely new challenge.
I can't figure out what you are trying to say.

I think climate change denialists have a brain. I think people with a brain are perfectly capable of making bad arguments.

Here's Alain Connes, Fields medalist, on how a mathematician works and should read a book [0]:

"To understand any subject, above all, a mathematician SHOULD NOT pick up a book and read it.

It is the worst error!

No, a mathematician needs to look in a book,
and to read it backwards. Then, he sees the statement of a theorem. And, well, he goes for a walk. And, above all, he does not look at the book.

He says, "How the hell could I prove this?"

He goes for his walk, he takes two hours ... He comes back and he has thought about how he would have proved it. He looks at the book. The proof is 10 pages long. 99% of the proof, pff, doesn't matter.

Tak!, here's the idea!

But this idea, on paper, it looks the same as everything else that is written. But there is a place,
where this little thing is written, that will immediately translate
in his brain through a complete change of mental image
that will make the proof.

So, this is how we operate.
Well, at least some of us.
Math is not learned in a book,
it cannot be read from a book.
There is something active about it,
tremendously active.

[...]

It's a personal, individual work."

I think they probably need more regional adjustments for the probability calcs I assume underpin their output. The UK Department for Environment, Agriculture and Rural Affairs, for example, has good open data statistics on crop growth, and stats are likely to be reasonably accurate since data is reported for subsidy purposes, and farmers are well aware agricultural fraud monitoring takes place.

OneSoil suggests 325k hectares of UK land dedicated to potato growing in 2017, over twice as much as the 145k reported by DEFRA; 378k ha of maize cultivation vs 195k according to DEFRA.

Other figures from OpenSoil such as barley and wheat are much closer to the reported figure and so may be fairly accurately categorised by its ML process, and some figures are going to be hard to fairly compare due to different categories or multiple crops per year)

At the same, having had a former colleague work on using Sentinel-2 data to classify land use, I'm well aware it's not an easy problem to solve.

I have completed all three courses in the series. It was a good supplement to other resources, especially 3blue1brown's Linear Algebra course on youtube[0] (mind-blowing, do check it out) but I wouldn't recommend it as a first course. The first two courses weren't rigorous enough for my taste (I am yet to find a rigorous course on Coursera), but the third was pretty good. You should take up books if you are serious.

MIT OCW Scholar(independent study) course on Linear Algebra by Prof. Strang[1] is really good and is designed for self-study. If you have the time, you could look up Coding the matrix[2] too. I read probability from Mathematics for Computer Science-MIT[3] and also referred Khan Academy[4] and PennState STAT 414/415 [5] for statistics and probability. StatQuest channel[6] on Youtube has handwavy but easy to understand videos on statistics for ML too. The Deep learning book[7] by Ian Goodfellow et al. has a couple of chapters at the beginning that gives you a fairly good idea of the mathematics required to get into Deep learning. Communities like r/AskStatistics and r/statistics on Reddit were really helpful when I got stuck.

I also chanced upon Mathematics for Machine Learning[8] book recently and it seems to be good. It has a chapter on optimization that is left out in most books but skips statistics.

Checked Hungry, where it stated soybeans is the top third crop, but in reality, soybeans are marginal there. To find outliers like that it would be interesting to compare data with published statistics.
yeah this is not good. Being a police officer, putting your life on the line to protect citizens... the guy showing up at your place at 3 am to deal with a crazed meth addict neighbour next door.. doing this dangerous task for many years. To have armchair 'law enforcement' experts in each living room of the nation linking to an officers behaviour on twitter, not having the context of the case, the background and previous actions of the offender on file... seems like a recipe for misunderstanding. I do think those new axon body cams are a good idea though, a cop can not worry about getting skewered on public media if he has real time video proof of being provoked. Southland (Cop show) had a good episode clip of this .

OK I think I've just ended up reading OP in a such a way that it appeared OP was saying that primates evolved opposable thumbs because they needed opposable thumbs, as if evolving opposable thumbs suddenly resulted in primates thinking "you know what would be awesome?

There isn't a "because".
> We also know that CO2 and temperature in the geological record are linked, with CO2 changes lagging temperature changes, which rules out CO2 as a cause of past temperature changes.

This sentence might have seemed logically sound to you, but it's extremely fallacious.

What this means is that the geological evidence is not sufficient to say that increasing CO2 concentrations increases temperature. Do we have other evidence? Yes, high school physics knowledge.

Radiative physics tells us how much heat an increase in CO2 concentration adds to our biosphere (an increase in another gas could have resulted in a removal of heat, but obviously this is a greenhouse gas). From that, we can very easily calculate the new equilibrium temperature. Then, climate science predicts about a 3-4x feedback almost entirely from water vapor and ice melting. You can argue about the feedback, but pretty much every person I offer this to just shuts down and goes haywire saying something about a "complex system". Yet these same people seem to know how to use a stove - you increase temperature when you add heat to something. The prediction of global warming really is that simple at its core. It's not complex.

>> After all, the number of available tenure-track faculty slots is essentially fixed—at MIT, there are approximately 1000. To create room for a new faculty member, an existing one has to leave. But after a brief dip, we thought, retirements should return to normal, creating room for new recruits.

I would have hoped for better intuition from professors at MIT. To me it seems obvious that if the average term of service lasts longer, you'll need replacements at a lower rate.

To me it just pointed to the fact that there are more people looking for such positions as there are positions. The later retirement just made an existing problem worse.
