Rail based transport on cities makes a lot of sense. In cities usually the only way to significantly increase transport capacity it to dig tunnels. Building on the surface is just too difficult.

When you build tunnels your cost proportional to the volume of earth you remove, which means your cost is the square of your tunnel diameter. Double the diameter, quadruple the cost.

This is where rail shines. Rail let’s you run faster, longer, vehicles in much smaller spaces, because the rails guarantee you won’t collide with the walls or each other. Just look at the London tube, with trains only slightly smaller than the tunnels. This means smaller cheaper tunnels, so you can build more of them.

In this system the tunnels already eliminate any real ability to reroute, so you may as well put the biggest vehicles in there and maintain them properly.

Even engines that "startup" more than once were pretty "out there". Over the years watching along, I've gotten the feeling that getting the engines to restart at all, and then restart in the right order and with enough consistency was one of the major breakthroughs.
As an undergrad, what's honestly needed is a variety of pace. I don't mind sprinting through a topic, but I can't do it for a whole class all semester. Students become complacent if you slow down permanently, but also fail to absorb information if you constantly push.

Run the blitzkrieg, but give me a week every once in a while to catch up and consolidate the knowledge.
Valid points, absolutely.

IRC and Freenode are great...if you're already in tech. About every third freelance client I speak with needs help with simple stuff - understanding how to get a host. Understanding how to point DNS to a service like Squarespace. They don't have that one tech friend to help them or know where to ask for help, despite the constant and saturated availability of chat rooms/forums.

So while we'll provide dev-to-dev mentoring, I really hope we reach this audience too.
British judge upholds arrest warrant for WikiLeaks founder Julian Assange
I've taught some undergrad courses, and unfortunately in practice this is a bit of an upstream problem. The pace of main line non-remedial courses is often set by the scope of course objectives, which in many cases are tied to accreditation. For higher-level more specialized courses, there is at least more freedom.

Basically, even something that seems like a simple shake-up in education often would require a top-down redesign when considering actual implementation. Higher education is highly conservative and bureaucratic in its processes.

Thanks very much, we'll take you up on it. Please reach out to askadevorg at gmail.
Non-major courses are an amazing opportunity for students to learn about a wide variety of scholarship from some of the top experts in those fields. The cognitive strategies / methods of inquiry of various fields vary significantly, and learning to “think like a historian” or “think like an ethnographer” or “think like an economist” or “think like a philosopher” or “think like a mathematician” etc. is incredibly valuable for future work and also for becoming an informed citizen and an inheritor of the richness of human culture. Liberal arts degrees are not supposed to be narrow job training.

The problem here is the debt students need to take on to go through college, not the college content per se (at least at the level of which courses students need; some of those courses themselves could use better content and pedagogy).

Vegans and cyclists both do receive a lot of flak. In my experience cyclists see a lot worse and I'm not sure why. Ian Walker noticed this too: http://www.cbc.ca/radio/the180/mmiw-inquiry-debunking-electo...

I am a cyclist who is sympathetic to veganism and eats less meat than your average omnivore. The main reason I still eat meat is that I am not convinced that most plant based diets are not missing something important. Never faced much hostility for choosing to eat plants, but can't say the same for cycling.

Thinking about it, I have never once met a preachy cyclist but have met quite a few preachy vegans. Level of preachiness does not seem to explain the stronger stigma cyclists have.
You have fallen into the trap of assigning some sort of meaning to the numbers themselves, when the difference between them by modulo arithmetic is the important part.

Some time systems roll over at midnight (24-hour base-60 clock) some roll over at noon (Julian day) and some roll over at both (12-hour base-60 clock). You shouldn't assume anything about a timekeeping system that has never actually been used.

Besides that, if such a clock had time zones, they certainly wouldn't be aligned to hours. If it had no time zones, you would have to know where on Earth the hypothetical conversation took place, and what the typical sleep schedule is there.

Though I'm sure people like me would be irritated by that leftover 400 second bit every day, where you don't get a whole kilosecond before rollover, and it may be that everyone arranges things by consensus such that it usually happens while people are sleeping, wherever they may be. So you might be right. Zero could correspond roughly to around 3 AM by the old clock, just like with the DST transitions.

> In my experience from organizing conferences people who self-identify as vegetarians eat milk products and eggs, though sometimes reluctantly.

That's why I used the word "variations". Vegetarians can be "baseline" (no meat), "lacto" (no dairy) and "ovo" (no eggs). A lacto-ovo-vegetarian would eat no meat, dairy or eggs, but it would still only be about diet.

Universities try to shoot for 90% correctness/retention for students. In almost every post-college career, that number is 70% or even less in order to be a successful employee. Being correct about facts 90% of the time is less valuable than having a better overview about more topics. I think schools should speed up in information rate but decrease the required retention for excelling. The most useful classes I had for my career were the ones taught at 900mph where I thought I understood nothing, yet I learned the most from them.
You may be right that the classics aren't necessary for critical thinking. To me, that's not even the main reason they're important. It's more about the type of questions we ask.

We study humanities to help us realize that the values we collectively hold didn't come from nowhere, and that those are the things we should really be analyzing and questioning. You don't get that in a statistics course. And through studying thoughts on the big questions of life from people in different contexts from us, we can gain power to decide for ourselves what makes life meaningful. Or is education only useful if it makes us a better cog in the globalized economic machine?

Reading the OPs link it looks like that animation may have had some dramatic license. They are going to do two more mid coarse corrections on the way to “Mars” if I am reading it right. Of course the red planet won’t actually be there on the other side when they get there.

Also note that you can’t “fall into orbit” around Mars, at least not with this sort of trajectory and without an aero rake heat shield. A real mars mission would require a third stage reignition for Mars orbital insertion.
That you've so internalized this oppressive ideology as natural or just is why I imagine people like Schifter feel so hopeless in the face of their circumstances.

It's unlikely we will leapfrog from human-written code to relying on black-box generated code in one step. Everyone's been pointing to AI being used to augment existing jobs, as opposed to outright replacement.

Ask HN: What does point 1 in redis manifesto mean?
I was reading Redis Menifesto(http://oldblog.antirez.com/post/redis-manifesto.html). couldn't understand what does point 1 mean. can you give me simple example explaining it?

Redis Manifesto:
1 - A DSL for Abstract Data Types. Redis is a DSL (Domain Specific Language) that manipulates abstract data types and implemented as a TCP daemon. Commands manipulate a key space where keys are binary-safe strings and values are different kinds of abstract data types. Every data type represents an abstract version of a fundamental data structure. For instance Redis Lists are an abstract representation of linked lists. In Redis, the essence of a data type isn't just the kind of operations that the data types support, but also the space and time complexity of the data type and the operations performed upon it.
A few ways to keep employees engaged and happy
I think it is for the same reason that many STEM programs require their undergraduate students to "apply for entry" to the STEM part of the program.

For example, at $GenericUniversity all CS students are listed as pre-engineering until completing calculus, data structures, discrete math, and a few introduction to programming courses. The school then "weeds" out students by making the initial coursework high-paced and somewhat difficult. After each round of courses a few "weaker" students drop out of the program.

Eventually, the students that make it through the pre-engineering curriculum apply for the engineering school and are admitted, assuming they have the right grades. The school now hopes that the students who have made it this far will be be the "better" students and thus will get better grades and be more likely to graduate. By weeding out the "weak" students before the students are in the Engineering School, the school can report a higher graduation rate and overall GPA for students in the program. Though everyone knows that many engineering students failed (or were failed by) the program, it doesn't go into the School of Engineering's reported stats.

I don't have any sources on this, but I do have numerous friends who work for universities and have heard this same story in varying capacities over the years.

If you think of stdin and stdout as your function inputs and outputs, then shell becomes very functional:

Pipelines Support Vectorized, Point-Free, and Imperative Style

http://www.oilshell.org/blog/2017/01/15.html

In a sense, a shell can only return an exit code. But it's better to think of that as an error handling mechanism rather than the return value, much like in C. In C, it's idiomatic for functions to return values with "out params" (i.e. a dynamically allocated a string).

Just like you can write C code that composes, you can also write shell code that composes. And in many ways it composes better than code in other languages.
This article is untethered from the mammoth amounts of research that's been done specifically on how people learn. The answer to this question doesn't lie in anecdotes about various professors' "philosophy", in fact that kind of approach is a huge barrier to actually improving the learning that occurs on college campuses. This is an opinion article, so I understand it's not thorough reporting, but the author should familiarize herself with the literature.

A book like https://www.amazon.com/Make-Stick-Science-Successful-Learnin... is accessible and provides a good survey of what we know about how the brain learns and remembers things, and how it relates to existing practices.

You will get me into trouble! I said 80x faster than the Python prototype. I did benchmark this vs Pandas over the years and depending on the usecase the two codebases trade blows with each other for static data. However for streaming datasets Perspective has a large advantage over Pandas since pandas does a full group by on every update, while perspective does its work incrementally using deltas.

This. The quantity that “truly” exists is the energy-momentum 4-vector P. A vector exists independently of any particular reference frame. Its components, on the other hand, depend on such a reference frame.

Seen from a given reference frame, the temporal component of P is the energy E, its spatial components are the momentum 3-vector p, and its magnitude is the rest mass |P| = sqrt(E^2 - p^2) = m. The minus sign rather than plus sign is due to the Lorentzian signature. It is very helpful to visualize these quantities geometrically as 4-vectors in 4-dimensional space.
I agree in spirit with this though I find internalizing the facts is less important than internalizing the method or theory of knowledge which they aren't getting either in my opinion.

Personal anecdote: I believe there is a broad and pervasive culture of extreme procrastination across liberal arts campuses (it's much harder to do this in the sciences because if you don't keep up you completely drop off). Vast majority of my peers were pulling all nighters and needed a looming deadline to finish any assignment. It is very difficult to retain information on no sleep.
The use of + as shorthand for sum (Σ would be clearer, but alas, not ASCII) is perhaps not ideal, but that's not an S-expression problem, but a function naming problem.

As someone who's been trying to pick up a consistent task tracking system, I have a question: Do you just always have a notepad with you? I tried something similar to this with a pocket-size notepad, but it was annoying and didn't fit very well with a pen.

So far the closest I've gotten is having a Google Doc, but it doesn't have the same flexibility that a hand-written notepad does (e.g. symbols, indexes, ease of writing/ access).

Teaching students and teaching in general is time not spent writing that paper that gets you your PhD / postdoc job / tenure. Eliminate as early as possible to make sure 1) the load from incompetent students does not potentiate and 2) to spend more time with & recognize the ambitious students that you can recruit for free work on your PhD / postdoc / tenure paper or as TAs if your department is rich.

Also, in Germany, university is free and publicly funded. There is only a small incentive for universities to pass as many students as possible and almost none for the immediate professors and doctoral candidates that do the teaching. Alongside with the public funding comes the implicit understanding that not everyone, for whatever reason, is meant for a college degree and so 40-50% of certainly engineering related students will drop out. No biggie, you are not 150k in debt, just do an apprenticeship.
That's true, except the guideline reads "Please use the original title, unless it is misleading or linkbait" and you can argue that once a vulnerability is fixed, implying it's still there is misleading. So we often edit those titles to past tense once that's more accurate. Same with "$site is down" -> "$site was down".

Colleges have become a confidence game where people exchange money for membership in an exclusive club. That's not say colleges SHOULD be this way, but the reality differs from the old rhetoric.

As Peter Thiel often says, why aren't all classes at Ivy League schools simulcast on YouTube if they're so great? We have the technology, it would be a boon to all humankind. But they make money off their exclusivity. (If the teacher contact compels you, why not at least make the lectures available to all and people can pay for the tutoring, you can probably keep enrollment up that way).
Wait, so, they're developing a single convenient mechanism for preventing apps from changing themselves out from under you, and they're giving it away for free? You only get the annoying "hey guess what I just 'upgraded' myself overnight, sucks for you if you don't like it" behavior if you pay extra? Well, sign me up, this sounds like a win, I'll be happy to simply refuse to pay for the behavior I don't want.
On the speed front, I concur. Back in 1998, when I was on summer break from university, I worked in a wines and spirits bottling plant. One day the labelling machine started applying wonkey labels to the wine bottles and a couple of hundred had gone through before the guy running the machine had noticed.

They weren't wildly misaligned, but far enough from true that we had to wash them off and run them through the line again. Took a couple of us most of an afternoon to sort it out.

Many, many years ago I had a student job with a small company doing industrial document finish, enveloping, and large-scale mailings. Apart from a still eaily induced paper eczema, the one thing I took with me was a rather comprehensive facility with the black magic of paper handling. Not an ounce of explicit science in it, but an awful lot of feel: When and how much to air and flex; where a grounded length of copper wire could work wonders; how much or how little moistening to apply, and where; how too touch the stream of paper and somehow know by the feel of the tip of your finger whether something would probably jam within a minute, and which tiny speed-adjustment up or down would probably forestall the disaster; when to to loosen or tighten this or that set of rollers because nightshift and the air getting cooler et cetera et cetera.

To this day I never just bang a fresh stack of paper in the printer tray. The full gymnastics of airing, flexing, feeling, airing and flexing again. I'm often laughed at. But my papers never jam!
