Let's try to look at it in isolation.

"parse-el" is used as a function, which takes one argument, the first argument when invoked from reduce (the accumulator), which is first [] then another vector (because of conj).

So "parse-seq" parses a sequence (named "form") and produces a vector, or nil. It applies "parse-el" to each form using reduce. When the result of any form gives a nil value, the whole result is also nil (see https://clojuredocs.org/clojure.core/reduced). The result is also nil if form is not sequential.

There is no other contract about "parse-el", it just should be able to "parse" whatever occurs in "form".
You could use it on your own with any kind of data that has a corresponding parse function.

A documentation string would have been nice, or different names ("parse-el"?)

Now, if you look at the usage of "parse-seq", you can see for example:

(let [vars* (parse-seq parse-variable vars)
....

And it looks like "parse-variable" parses a form and returns an instance of Variable.

(defn parse-variable [form]
(when (and (symbol? form)
(= (first (name form)) \?))
(Variable. form)))
The graph on page 11 is particularly interesting.

It looks like fluid IQ peaks around 24 then rapidly declines until around 30. Between the 30 and 50 the decline somewhat levels off.. i.e, doesn't decline a much during that period and crystallized IQ increases slightly.

After 50, fluid IQ resumes a rapid decline at a steady rate until about 75 where it really begins to tank.

But you are right, for the timescale in question the IQ difference is pretty small. I'm sure everyone reading this is very smart so a difference of 3 or 4 points shouldn't concern them all that much :)

A couple of things I wonder about, lack of physical activity (I've read) helps hasten cognitive decline. Sitting in a chair for 20 years as opposed to being active for 20 years, wonder what difference it makes? Perhaps sitting in a chair and thinking more than offsets the difference?

Also I wonder about so many world leaders being well over 50 or 60, for example Supreme Court Justices in their 80's. What would happen if a long resume didn't matter so much and we had a slightly younger (not 24 god forbid!) group running government? Just a hypothetical question.

But from that graph, if you are going to hire a 30 year old over a 45 year old (because "younger people are smarter") it appears you'd actually be better off with the 45 year old in sum (crystallized and fluid) intelligence plus whatever experience bonus.

> I want a self-driving car of my own, but I don't want to share it with anybody else.

That's assuming that you will even be able to buy a self-driving car as an individual. (Or at all.) I find it highly plausible that car companies will expand to fill the entire vertical of car design, manufacturing and as-a-service operation.

The service-oriented model was not really viable until now because the model of individuals buying cars was pretty much the only accepted option. But car companies have already started the vertical integration (many of them all have their own carsharing subsidiaries).
It’s not rare at all and it’s for a lot more than just the medications described. I can recall erectile dysfunction drugs, anti depressants, pains medications and other miscellaneous drugs.

Are you saying a country with 4M people that emits the same as a country with 100M people is doing OK?

Per capita is a useful measurement (but not the only one).
Yes, it is a multidimensional competition. Price is not the only variable.

So is service when you make a claim (I've been "screwed over" twice when making car insurance claims). And so is obfuscation of services provided. So is money spent on advertising. And lobbying.

All insurance companies compete with a unique strategy on the mix of variables.

This is the classic "appeal to nature" fallacy. On top of that, we don't know much about the diet of ancient humans, including how often they actually got to eat meat. Natural selection isn't wise, it's just an uncaring response to the environment. The environment has changed dramatically.
This may not have been an age thing, and more of being threatened by your experience thing. Could also be that they were so clueless that they couldn't put together that you could obviously do java 8. A lot of places writing pretty basic software really do think they are Google and have weird impossible to meet interview standards that no one working there could ever pass.
The hard part about Clojure is the editor tooling, like learning Paredit and how to evaluate code in the buffer. And then training yourself to actually do it.

It's similar to training someone to use Vim in that it's quite a different tooling set and workflow they're probably used to. I think that's the main barrier.

The language itself is pleasantly simple. And tools like Paredit make it one of the most pleasant languages to write. It's just hard for someone to appreciate Clojure until they put in the work to credentialize in its tooling.
Insurance companies are actually undergoing something of a silent revolution in terms of underwriting policies. Many of them are upgrading to some sophisticated machine learning algorithms instead of the traditional actuarial tables. Assuming tesla cars are really safer you would see the algorithms pick up on that (there may be some lag until they catch on) and then price the policies appropriately, assuming that the insurance company is willing to pass that value to the customer.
The other half of AI is data. Valuable propietart data. ie credit card transactions or checkin data from foursquare
No, I didn't say either of those things.
> Meat at twice the price would probably solve the problem.

While true, it basically sends the message of "If you have enough money you are free to do what you please to the detriment of the planet."

I.e. one (or one thousandth, given his carbon footprint) less Zuckerberg? I could get behind that. Heck, I supported NPG back when I thought humanity had a chance.
Wait, I'm confused... LNG is pure methane. Are there rockets that use methane that aren't storing it as a liquid? I would have to guess that any rocket using methane would pressurize it enough to be in liquid form for storage, anyway. Surely they wouldn't use methane in a gas state... It would take up far too much space to be practical.

Also, in the actual MOOC, for which you have to register at https://www.fun-mooc.fr/, the videos are also available dubbed in English. (Except some that are not part of the "actual" course that give tips on how to use the environment.)
So what are you suggesting instead?

> That's the core concept there: start with a working but basic model and continue to extrapolate from that as time goes on.

This has literally nothing to do with few-shot learning though. You can always make a crappy model with a small amount of data and then improve it as you get more. And my point is that if you have a competitor with several orders of magnitude more data, their models are almost certainly still going to be better than yours.

Few-shot learning will probably be able to improve the baseline of what you can do on certain tasks, but you're not magically going to learn a sufficiently accurate cancer diagnosis algorithm from 5 radiology images.

The best case for few-shot learning is that you go from "worse than the alternatives" to "good enough for some people to get value", which will probably happen a few times, but is going to be a minor phenomenon.

Fowler is paying a _very_ high price for speaking out, not everyone can do that, and I don't think this should be expected of anyone. It is a sacrifice. Will her actions pave the way to make such overt sexual harassment less common in corporate environments? Perhaps.

Have you really read the YAML spec? It's a rather complex grammar. I get that YAML is visually cleaner than JSON; however, unless we're constrained to very trivial use cases there's probably too much to think about. JSON's strong lack of TMTOWTDI is an asset here.

As for XML: namespaces, DTDs, entities, XSD, XSL, XPath, and on and on, have resulted in some absolutely horrendous architecture astronautism. XML itself is (mostly) perfectly fine but there are too many unqualified people in the industry wielding XML, poorly, and creating massive headaches. XML also presents some interesting security challenges.
I feel like you have drawn a line in the sand and said , "This is the proper amount of knowledge to have, anything more than it is wasteful and anything less is ignorant".

How did you verify your physics and engineering knowledge? Did you run hundreds of thousands of experiments to verify every single law and property of physics? At some point you are reaching a piece of data you learned from someone else and did not verify or that is an assumption because it's currently unknown how to explain or takes too much effort to verify while living your life.

On top of that, the OP was talking about how it was impossible to verify _everything_ in our lives nowadays. You mentioned nothing about biology or chemistry. How do you know your diet is the proper one? Are you sure about every chemical you interact with and how it affects you? Do you properly understand copyright and other IP law when you make a YouTube video using someone else's work? Did you get the right permits to put up that shed on your land that complies with the regulations from the 7 different layers of polity that cover you?

What absolutely astounds me is how Facebook literally has failed to offer anything of substance to empower people from their massive user base.

For example, it should be "three clicks and you're in" to found a virtual company and state "this is the problem we are going to solve, who's with me" - and another person from across the globe should be able to say "heck yeah let's do this" and then Facebook would say "that sounds great we will host your site/app/whatever and when you show traction on that problem you will hit level 1 funding of "X" and so on and so on..."

Facebook has the daily attention of over a billion people they claim, yet they literally just steal their energy and provide no building power.

Start a fucking economy and empower people unlucky enough to be born in a far reaching place such as the Congo but smart enough to know how to solve various problems affecting many.

Facebook is not making the world a better place until they do something like this.

Of course market demand and other factors matter but the point of this article is that large tech companies are now a barrier on the way of small startups to their success.
We all see that now, most startups fail and even if some of them gain some traction, they are being bought by big guys.
And one of the main causes of that is the outdated nature of large corporations. Nowadays, one of the main platforms to promote your company is Google. However, google advertising is good for those who pay more. Thus, companies with more cash have a privilege over smaller companies even if the second ones do their job better.
And that's only one example with one large corporation.
To conclude, big guys, which were praised by the whole tech community all the time are now a barrier on our road to progress.
Is there no HN rule about making a fresh account just to incessantly troll a single comment section?
I think this attitude gets in the way of finding what is really happening. Are there companies with bad management? Yes, but I think that is generally the exception. As someone who has been a manager and a 'higher up/exec' at various points, I never cared about someones age. I wanted people working for me who could get the job done so I could get my bonus/promotion/whatever. No managers that I know want mediocre or ass kissing, because none of that helps get the job done which is what really leads to more money (through bonuses and advancement).
Strong typing, powerful package and namespacing facilities, a good object oriented system (if you want to do OOP, that is), interactive development with a REPL that can tell you easily which function calls which others, etc.
Good point in differentiating between optional and required activities. I definitely think it is more important for a father or mother to work reasonable hours than someone like me. I just don't like the attitude some companies have that because I am 23 I have nothing to do so of course I'll work longer than I need to.

Thanks to the informative replies, I googled around and found some articles comparing of the 950 and 960. Apparently it's significantly faster, and doesn't throttle from overheating as soon.

Now this may be off-topic, but this one article really struck me as bizarrely sexist, an archetypical example of how the computer industry and press are casually hostile towards women.

What the fuck is up with this site Custom PC Guide and their "tradition" in "every article about Samsung SSD"? Is this stuff coming from Samsung, too? Did part of what I paid for my 950 Pro go to paying for that beach photo session, or to Custom PC Guide through some advertising or affiliates program or free hardware samples somehow?

https://www.custompcguide.net/review-and-comparison-samsung-...

>But first and most importantly, let’s address the tradition that started two years ago [2014][2015] and appeared strong in every article about Samsung SSD on here ever since then. It’s been one of the reasons why you guys keep reading, it’s certainly no different this year now: hot girl photo.

>Let us bring forth the cute kpop band Girls’ Generation who landed a gig to represent Samsung and the brand recently. They are promoting Samsung laser printer in this photo but I don’t think that’ll matter to most gentlemen. Also at this point, it’s safe to say that the performance of Samsung SSDs increases in parallel to the beauty level of their female reps.

Once you get past the girlie picture, search for "piss":

>They piss on and kill each other to show dominance or they get on fire. Nah, just literally kidding. But heat will be an issue here at some point, especially how the packages are stacked on top of each other like this in both the 960 Pro and Evo.

>The NVMe interface alone is still just a toddler in the PC hardware world. Who knows if some day in the future it’s learning to walk and just falls flat on its face like my son when I accidentally tripped him. Using the Force.

>The Samsung 960 EVO is truly as fast as the Samsung 950 Pro, faster even in many benchmarks. That is insane, for a TLC-NAND solid state drive to be honest. It’s like Samsung decided to send the 850 EVO to Shaun-T’s bootcamp to work its ass off under the 90-day Insanity training then straight to Sagi’s bodybeast without taking a break; At the end of the program, now we have this super athlete, super fit and super hot female rep who also makes the 960 EVO goes faster every night.

Yes, and that's a big part of my point. This is an actual problem, and we (the software development industry) should try to fix it. Or at least make it suck less.

When I switched to applying through AngelList I had much better luck, and that's how I got my current job. Part of that is that early mode startups are picky about other things than later mode startups or big companies. But mostly I think it was because actual engineering hiring managers were looking at the applications without requiring them to go through an HR/sourcer/recruiter filter first.

I suppose that would depend on your view point.

From that viewpoint I say tough shit if you get swamped by these requests.

If we found that a group of companies had made a business model of dumping garbage in public areas through a legal loophole, Id hope that people wouldn't be saying that we have to figure out some solution that's reasonable for all parties when the government goes to stop that

I get what he's saying. The internet used to be peaceful grassy plains. Now it is loud bustling New York with bigger fish that are out to get you. This doesn't mean you can't disrupt everything, but now you have to outrun this new establishment that reinvests all its money into eating you more efficiently. Companies like Facebook already have giant audiences, and copying your product can be done virtually overnight.
