How to select a data science bootcamp? Tips?
I'm looking into data science bootcamps in NYC (or potentially online). Any suggestions for identifying the better ones (assuming they exist)? For example, I hear that bootcamp review sites lack objective reviews.

Also, do you know of anyone who has successfully full-time self-studied for a few months to obtain a entry-level position in the field (or a related title such as data analyst/ data engineer)? If so, it would be great to hear about their approach.
> it is true for very large classes of functions.

While it is, yes, from the point of view of a human counting them, very large, measure-theoretically it is a meager set. If you were picking functions at random from the space of all possible functions, you would never (i.e. with probability 0) pick one with a useful Maclaurin series.

It may be an undetermined distance away, but there will be a behavior bubble until the way we engage (in a linear format) will be disrupted. Then there will be another 'scatter', and we will re-form into different version of engagement (web 3.0?).
> After watching Michelson play bridge for a while, you could predict more or less the kind of mistake he would make, and it was not unrelated to the American champion’s description of his chess game. He would make a bid short of game, but, after getting the bid, would see that, if he took and made two long finesses, he could come in with a little slam. Of course, a little slam would make only a few points difference since he hadn’t bid it, but he would take the two finesses and not only lose both but lose his bid on an absolutely “lay-down hand.” He was a rather small man, as you know, and he would look with almost childlike incredulity at the ruined remains of his daring invention of two long finesses where none was a sure thing.

If anybody needs translation:

In bridge you bid how many tricks you will take; there are 13 tricks and the minimum bid is 7 (i.e. you will take over half). If you make at least as many as you bid, your score is positive, if you make fewer than you bid your score is negative. You get bonus points for bidding at a certain level; "game" is 9-11 tricks depending on the situation (10 tricks is the most common for reasons I won't get into here). "small slam" (or little slam in this article) is 12 tricks and "grand slam" is 13 tricks.

You have two opponents in bridge and a finesse is a play that depends on cards being in the correct opponents hand. Most common is which opponent holds a king when you have an ace and a queen. If you can force them to decide to play the king or not before you play, then you beat the king with an ace, or beat the lower card they play with the queen. A "long finesse" (called a "deep finesse" today) requires more than one card to be in the correct position, so attempting one is a move of last resort.

Now the translation. He bid to make 9 or 10 tricks, but saw that he could make 12 tricks if all of the cards were in the position maximally lucky for him. Since he did not bid high enough to get the bonus for winning those, the reward is tiny, and he should just make the obvious plays to cover his bid. Instead he took the risky play and ended up not even making the 9 or 10 that he bid. This is the sort of mistake that even an intermediate bridge player learns not to make very quickly, but a beginner couldn't make this mistake at all because they wouldn't see the opportunity. So Michelson is smart but a terrible bridge player.

I'm struggling to think of an equivalently bad play in poker; maybe staying in the pot when your hand is the low-pair after the flop and several others have already called?
I bought my own e-bike for use in Atlanta, and commuted exclusively by bike for nearly a year, including the previous winter. I had about a 4 mile commute and it turned it into a leisurely 15-20 minute ride, partially on the beltline. Parking is free, and I could bring my bike into my office. The real advantage of e-bikes is just how easy it is to climb hills with a 500-750 watt motor.

I've moved jobs and am out in the burbs, but plan on moving back pretty soon.
Well, in the case of WeWork, a current holder of WeWork stock might "undersell" it because their basis is already so low. It's a huge profit, and you get real, hard cash in exchange for the security. It's not a bad trade if you believe the public market won't believe in your business (regardless if you think it's the best thing ever), and you also want millions of dollars.

Pedantic note:

It’s not “.7kW per hour”.

Watts is a measure of power, it’s already Joules/second.

You just want “.7kW”.

For 6 hours, you still won’t get 4kWh, because you need to adjust for less than ideal angle, and less than full sun days.

But if you got 3kWh on a good day, that’s still 10-12 miles of additional range.

‘It’s Over. It’s over for Apple.’
This sounds like the start of a Zen Koan.

A master approaches an apprentice, the master has a software engineering project for them both to work on, and tells the apprentice to make it clear when they were ready to start.

Weeks pass and the apprentice never says anything, but just hacks away at their own machine.

The master asks them why they aren't ready, and the apprentice replies, "We'll be ready once we've customized vim/emacs into a useful editor. But don't blame me for the delay, you have just installed stock vim/emacs, you haven't even started your customization", the master replied "I've already finished".

Then the apprentice was enlightened.

This isn't a comment about Holberton (which I can't speak for), and sure an $85k cap for a school with no instructors is high, but I'd just like to point out that the methodology of "I'm going to find 3-4 students who want to complain about their school off the record" is not a good way to consider the quality of schools.

Imagine what would happen if someone went after... any school you've ever attended with such an approach. Think they could find a half dozen students to rant and rave about how the school was awful? Certainly.

Of course, I'm biased - she has another thread about Lambda School (where I'm CEO), and reading the criticisms I know exactly who the students are. It says something that of the 6,000+ Lambda School students of all-time I can pick out the 3 or 4 complaining from the complaints, and if you dug into those students' complaints you would find there's much more at play than what is mentioned.

This year I finally found a flexible and comfortable job. I work only 25 hours per week (more or less). The income does not make me super rich (like FAANG engineers) but I live comfortably with the money.

I consider this situation as my recent success because I have a lot of time to work on other things (research, moonshot projects, online businesses).

I just published a book about blockchain this year. Last week I released an opensource blockchain project. Later I want to build an online educational business (something like pyimagesearch.com, egghead.io) but this time it is not about blockchain anymore. :)

In the future (maybe 2 years later) I want to do some research on drone.

By saying speed of light, you make the assumption it is the same in any direction or reference frame. This was not known to be true, and is still the subject of some question, hence the more modern experiments measuring the speed in a fixed frame to compare to other frames.

For example, what is the speed of a bullet? It depends on the observer (as does velocity, but velocity is a more accurate thing to measure for this reason).

It so far is experimentally true that the velocity of light has the same magnitude (up to experimental error) in any frame, which was a tremendously crazy result at first, so much so that it forced mankind to give up the notion of constant flow of time, and it forces space and time to "rotate" into each other in a weird manner called space-time.

So the velocity of light is the proper term to use in an experiment.

The best leaders value their words, and use them sparingly.

Professionally, I won a poster award at a conference, mostly for my slick R ggplot visualizations analyzing delirium in elderly hospitalized patients. I've never won an award for my research or coding, so that was a joyful moment. Especially, given that 2 months earlier, I was crying under my desk on my 30th birthday due to work pressures and feeling totally lost trying to build huge datasets with SQL as a beginner.

Personally, I was asked to join two different folk bands, playing piano and singing. To any classically trained musicians, I'd recommend trying folk, there are great opportunities for your trained technical skills and playing with others (rather than solo) has been very uplifting to my musical happiness.
7x-ish more expensive than provisioned capacity, to be exact. For test and experimentation, it makes sense. However, if you have constant traffic in production, you'd have to consider switching between auto-scaling and provisioned capacity, but I think that can only happen once every 24 hours.
I don't know if encouraging pedestrians to step into the way of a vehicle is the wisest decision. If a car doesn't slow down, it will infringe on the sidewalk. At least right now, a car under control can travel in a straight line and be reasonably assured that their path will be free of people.

It seems more and more that she just got incredibly lucky signing up for one that wasn't a scam.
How Did Rust Get So Many Things Right?
One thing I've been thinking about lately with emulation: why can't we replicate and use the original hardware more easily?

There's lots of knockoff console replicas out there, so it seems like the chips can still be manufactured. Wouldn't it be fairly cheap to build a board/chip that contained either the original chip designs from classic computers/consoles, or hardware-level emulated chips? Seems like you could stuff several of those retro chips onto a single expansion board. Then emulation software could tap into this "emulation expansion board" to make use of the real chips. Is this all crazy talk or does any of that make some sense?

This is a really big problem in America and it needs to be addressed head on, regardless of how uncomfortable the consequences may be.

LEOs hold a sacred role of trust in our society - they maintain the potential application of the use of lethal force. With that power must come the most severe of guardrails, to which unionization is completely antithetical. Our civilian control of the military is internationally lauded, but we lack full civil control of our own law enforcement.

I think the way to go about this is to break up the law enforcement departments into smaller scoped independent roles with enough potential redundancy to be able to institute reforms via divide and conquer. Remake law enforcement from the ground up in this way, and deny the new institutions public unionization by law.

If the existing police unions strike, they must be dealt with as severely as mutinous armed forces would be; they should be subject to a court marshal form of adjudication with the same penalties that a military officer would face for desertion and endangering public safety.

Start building new parallel law enforcement institutions now, prepare for how to maintain civil order in the face of a strike, then start dissolving the old institutions. It’d also probably be wise for the FBI to maintain a comprehensive database of federal, state and local LEOs in case some go underground and attempt to undermine these efforts through domestic terrorism.

This is extremely black and white thinking. You are trading your safety for theirs when you insist that no one but pedestrians be in certain places.

Whether they are breaking the law is rather irrelevant, unless you think the problem would be solved by making riding bikes on the sidewalk legal (which you obviously don't). You can't say "the law shouldn't be changed because that would be bad" and then "it's bad to do it because it is illegal". That's circular logic.

Also, not everywhere is riding on a sidewalk illegal (example found with a quick google: "The City of Los Angeles permits riding bicycles on sidewalks, even in business districts, as long as cyclists do so with regard for the safety of pedestrians and property").

You gave an example of kids rushing out of a store. But if bikes/scooters/etc are regularly on sidewalks, wouldn't they then be taught to be careful? I mean, kids have to intermix with cars in parking lots (far more likely to cause death or serious injury than getting hit by a bike), and they are taught appropriate safety.

Who knows, maybe a kid getting a painful scrape or bruise by running into a bike will save their life later by making them more attentive next time, so they don't get run over by a bus. If you are going to list anecdotes (observed or imagined), you should consider all such possibilities.

The author is muddying the water for effect, that's why his explanation is confusing. To understand what he means, you should ignore the results expressed as percentages and instead focus on 1:19 vs 1:99.
