Quite true.

For one, it would show all young developers that there was a time where OS were implemented in languages other than C.

Is SF any better with regards to transportation? The T stopping at 12:30 is definitely an issue. Boston has always felt strange to me in that you can walk from Forest Hills to Alewife in an afternoon, but like you said, if you want a cab or a ride at 2am, you're SOL.

Most of the people I've met tend to be 20s and 30s with jobs downtown. The college culture is pervasive, but I wonder how much it really affects those of us who aren't planning to leave any time soon.

Heh, this is pretty neat.

I just noticed that there's a little color swatch on the right side of the screen that allows you to change the background color. Combine all this with a nice color scheme and you can get something that looks really cool.
Indeed. In my experience, looser requirements in this kind of thing just leads to tears on the part of client and server implementations. I'll happily reduce some of the MUSTs to SHOULDs or MAYs if it makes sense for the communication channel to consider them optional.

One thing that for years made Fortran stand out is that the language explicitly assumes all arrays passed in to a subprogram have no overlaps.

Thus a Fortran compiler doesn't have to do anything special to make sure it preserves order when storing and accessing from two different arrays. Therefore the compiler can be much more aggressive about unrolling loops and changing the order of operations.

By contrast, given a loop like

for( i=0; i<N; ++i ) {
y[i] = 2*x[i];
}

a C compiler has to assume that y[i] might be the same memory location as x[i+1], for example. Thus it has to ensure that the load into y[i] is complete before accessing x[i].

This is one reason you see a lot of C code that does numerical work hand-unrolled, with explicit stores, like this:

for( i=0; i<N; i+=4 ) {
xi = x[i];
xip1 = x[i+1]; xip2 = x[i+2]; xip3 = x[i+3];
y[i] = 2*xi; ... y[i+3] = 2*xip3;
}

Now that C provides the "restrict" keyword, a smart C compiler can do many of the same optimization tricks that Fortran has had since day 1.

Obligatory Vimes quote:

The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.

Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.

But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.

This was the Captain Samuel Vimes 'Boots' theory of socioeconomic unfairness.”

So the regen force would still exist (?), just it would be really small, and so taking a long time to fully stop. Would it be possible to apply a reverse torque to the electric motor to decelerate faster. For example, I'm thinking about a hypothetical race car that could have no traditional hydraulic braking system to save weight, a large amount unsprung.

Really incredible quote
This is really a great quote... and it is my favorite!
How could anyone hope to accomplish anything halfway great without being grandiose, obsessive and deluded?

Kurzweil has already done enough to prove he's not simply deluded. It seems like every week there's an article that comes across HN about how all great innovators have a capacity for self-delusion. Kurzweil has consistently shown himself to be a great innovator, and yet people dismiss him as a crank because he has the gall to continue to reach for "impossible" goals.

Who is creating the majority of friction in the drug trade? Nation states and their war on drugs.

Silk Road is using technological advancement to remove as much friction from the process as possible, but it's obviously still non-zero, just like any market in the world.
Similarly it's expensive to be disorganized. I have hesitated in the past to buy a quality fall/winter jacket because the risk was too high that I would lose it. I cleaned out some boxes recently and found three low-quality sets of Allen wrenches. If I had bought a nice set, I probably would just have been out more money when I lost them anyway.
There really isn't much to this article. From the title, I thought it was going to discuss the problems that people face when they live paycheck-to-paycheck and/or near the poverty line, which is a story that's been told but bears repeating and further exploration.

Instead, it merely remarks that some US corporations have noticed an upward trend in the number of their customers who are a part of this very predictable cycle (pay/benefits days, usually at the end of the month), and mentions that more "middle-class" are now a part of the cycle.

However, it doesn't delve much deeper than linking it to the recession, and doesn't offer any insights into how these businesses are adapting other than vague references to "big data" (with a hat-trick of references to the term).
Interestingly, that's a common Norwegian saying ("Det er dyrt a vaere fattig"). My two primary takeaways from it :

1. Don't skimp on quality when necessary.

2. Have empathy for those with less means. Getting out of the rut of low-income swpending patterns is often non-trivial.
Ciplactin (antiallergic drug)
If you think of a type as a set of possible values, then a subclass is actually a supertype—a superset of the possible values of its parent class—and likewise a superclass is a subtype.

Nope. A subclass is usually (not always!) a subtype, not the other way round. Or, more specifically (and accurately), most statically-typed class-based OO languages treat subclasses in their type systems as subtypes by default, i.e., they assume that a subclass instance can act as an instance of its superclass, LSP-wise. This, I believe, is as accurate statement as one can make (on this level of generality).

The “is-a” relationship is saying “for all instances I of X, I is an instance of Y” which is essentially the definition of superset. That is what the Liskov Substitution Principle is about.

It's a definition of a superset, if Y is the superset and X is the subset.

In C++ and other languages with support for object-oriented programming, a subclass is not necessarily a supertype: virtual functions can throw “I don’t make sense in this derived class”.

That's a part of why I believe that static typing doesn't make too much sense when it comes to OO languages (with (sub)classes). If static typing is supposed to take care of subtype assignability statically and the semantics of the behaviour of derived classes can break the LSP assumptions, static typing becomes sort of worthless.

In general, I agree with you. However, modern Fortran also has a strong module system, and some nice looping constructs (like explicitly-labeled loops that let you control "breaking" and "continuing" in nested loops quite easily), that made me like using it for even non-array-oriented programs (for other reasons, I don't use Fortran so much anymore).

The only thing I absolutely hated about Fortran for parsing data files is that, according to the standard, a text file has to end with what amounts to an empty line. Many Fortran environments break this rule intentionally, but occasionally you'll find one that follows the rules. It inevitably bites people who forget that their last line of data must be followed by a newline, or else the line may never get read.
In practice, you'd focus on factories, powerplants, the road owners, auto-makers, etc. This is similar to how regulations already work. The regulators tend to ignore the rogue backyard barbecuer and instead focus on the big polluters.

Also, aggregation techniques could be used for both defendants (polluters) and plaintiffs (landowners and other people being poisoned.)
Regarding your Roman Fire Brigade example, we can now produce a much more effective system with modern bookkeeping technology. Instead of paying for fire protection as your house burns, you pay for the fire protection in advance. In fact, that's already the way it works in some parts of the world. You pay the fire department in advance (so they can pay for the upkeep of their machines), and if you don't, they have no obligation to put out your flaming house.

They are selling an essentially worthless product to unknowing people[0] who believe their claim that ‘electromagnetic field radiation’ is a ‘threat’.

Now you might certainly argue that there are certain dangers associated with electromagnetic devices and that we don’t know enough to fully declare laptops ‘safe’. You would certainly be quite right about that - x-rays are dangerous and we can never be absolutely sure.

However, electromagnetic emissions from a laptop are

a) closely regulated in all (relevant) parts of the world with strong limits on the power a wifi device, for example, may emit and those limits are generally found to be more than safe even during extensive use by the vast majority of the scientific community

b) far surpassed by other items such as CRT monitors or washing machines

c) even further surpassed by this big device in the sky providing us all with infrared, visible and ultraviolet electromagnetic radiation

d) in many cases not even absorbed by the human body – otherwise the wifi signal would drop noticeably if someone stepped between you and the access point.

Furthermore, let’s look at least at one of the claims on the project site:

Very recently, new research is suggesting that […] malignant melanoma and asthma
[,] can be tied to some facet of our use of electricity

The rise in malignant melanoma are usually tied to sunburns[1], genetic disposition, increased livespans and better diagnostics. Unless this guy claims that use of electricity allowed us to go outside more or changed beauty ideals from ‘pale white’ to ‘remotely healthy’, I don’t see how electricity could have caused that. The idea that asthma can be linked to ‘use of electricity’ is…well.

And last but not least, this product, by design, blocks radiation emitted from the laptop’s bottom – hence ignoring everything emitted from the top and – more importantly – the screen. So even if electromagnetic fields as emitted by laptops were a threat, it would only protect your testicles, rather than, say, internal organs, bone marrow, your brain or your eyes. Note that while electromagnetic fields decay with 1/r² at distance, this decay is nearly negligible at such distances and air doesn’t absorb it in any noticeable ways, so that your brain likely gets as much as your lap anyways – especially since the screen of a notebook is even built to emit such radiation!

Really, this is just another one of these items sold to people complaining about headaches from mobile phone antennae before they’re switched on.

Note that I’m not saying heat emitted by some laptops is not a problem, but trousers help with that easily – and decent laptops, naturally.

Kurzweil has grand ideas, thinks out of the box enough for people to call him crazy. I would guess some of those are the kind of grand / crazy ideas larry and company want to pursue too.

An explanation for India's weird cartographic laws is in order.
India has a ceasefire line with Pakistan as a border and significant claims held by the Pakistani's. Moreover with China it has an undefined border, where China is not even exchanging maps showing their claims.Published maps are taken as proof of 'facts on ground', during negotiations and arbitration. Combine this with a big bureaucracy and you have these laws.
I wish we could not have these laws but given the present scenarios and an unfriendly giant neighbor, these laws are justified.

One thing that for years made Fortran stand out is that the language explicitly assumes all arrays passed in to a subprogram have no overlaps.

There's a HUGE number of languages that don't allow aliasing in this way. I wasn't thinking about "how to improve C", I had APL, J, K, Q etc. in mind, as well as languages that implement mass array processing with similar semantics in terms of a more conventional syntax.
> This functionality was extracted out of a general purpose framework used by a number of applications that made heavy use of it

> You pay the fire department in advance (so they can pay for the upkeep of their machines), and if you don't, they have no obligation to put out your flaming house.

Two problems:

1. If not enough people pay for a fire brigade, the fire brigade is complete shit even if I do pay for it, because I can't fund a brigade all on my own. (If you tell me to move, you've lost the argument.)

2. If my neighbor's house is on fire, I really, really want the fire to be put out even if my neighbor hasn't paid for the brigade. I do not want the brigade to wait until my house is burning. (If you tell me to move, you've lost the argument.)

3. If you tell me to move, you've lost the argument.
Eh? The title is "To Kill a Mockingbird", and not "How To Kill a Mockingbird".

The title derives from this line in the story (paraphrasing from memory here): "Kill all the bluejays you want, but remember it's a sin to kill a mockingbird."

I worked at WalMart for 3 years. I worked overnight doing inventory management and I saw exactly what the CEO described. One thing I noticed that he didn't mention is that a large number of the people I worked with were part of that group of people waiting at midnight to buy their baby formula. I always felt like the wages at our store were subsidized by the government.

All of the people I talking about worked full time. They all had ungodly sums come out of their paycheque every two weeks to pay for health insurance (from what I understand it was not a great plan either). I don't really know what kind of point I'm trying to make here. On one hand it's nice that there are a lot of cheap options at WalMart for people on small budgets. On the other hand, it's sad that so many WalMart employees (in my own experience) are the ones who so badly needing to take advantage of those prices.
Regardless of the actual subject, it looks like an excellent analysis. I haven't verified the maths, but I like that he includes every possible calculation, source code, and external reference that was used. A very academic and data-driven approach.
When you don't have enough to cover all your bills and keep appliances up, your spending patterns change dramatically as well.

What "realities of the drug trade"? Any drug sales happening on TSR are by small-time manufacturers and dealers. There are no shootings or stabbings on TSR. The cartels don't have any reason to use TSR. I think the nature of TSR prevents most of the "realities" you're citing.
You're not convinced this actually happened? When I was in elementary school, I regularly (ie. several times per semester) got into arguments with my math and science teachers over stuff this dumb. There's no need to make up something like this when you can find it in the real world so easily.
