High speed rail:

It's like combining a buss and a plane. Except that it's going to be either slower (then a plane), more expensive (then a bus), and doesn't actually want to go were you want to go (compared to either).

It's a huge step backwards. There is a reason why people stopped traveling by rail in the USA years ago. And (hint) it wasn't because of lack of government subsidies.

Automobiles and busses get you were you actually want to go, were as with rail, more then likely, you have to travel a few hours to get on the train and then you have then travel a few more hours to get were you want to actually go. And beyond intermediate distances a plane is just obviously faster then either.

So that leaves passenger trains purely as a nitch product. They have to fill the gap between "farther then I'd like to drive or ride a bus" and "closer then flying makes economic sense" and it still needs to be combined with: "enough people want to do this very specific route every day to fill the trains". There are only very few areas of the country were that makes sense and they are already serviced by trains perfectly fine.

High speed rail is a boondoggle. It's a waste of money and resources that is much better spent on something that people actually will use. The only way high speed rail will be a success is if the Federal government managed to make travelling by plane so unpleasant that people will be willing to take sleeper cars across the country. This is extremely unlikely because the Feds are going to make train travel as unpleasant and stressful as they made the airliners.

I think coal plants are vastly more efficient than they were in 1913 from improvements in materials technology, higher pressures and more efficient combustion.

Wouldn't the sentence 'I want to put a hyphen between the words Fish and And and And and Chips in my Fish-And-Chips sign' have been clearer if quotation marks had been placed before Fish, and between Fish and and, and and and And, and And and and, and and and And, and And and and, and and and Chips, as well as after Chips?
I graduated from the University of Chicago, and they have a handful of undergrad classes using functional languages. The intro comp sci courses were using Haskell for the honors class, and Racket for the non-honors version when I took it. The compilers course there is taught using ML, though the fact that UChicago has several faculty who work on the development and maintenance of Standard ML may have something to do with this.

They're tricks, but they're far from incomprehensible. In my experience, both with this sentence and the buffalo one, there's a certain mental click when one "gets it", after which the sentence makes sense and one can "feel" its grammatical structure. It's a curious and rather Chomskyan experience. Before that, of course, the notion that such a string of words might mean anything is absurd. "Getting it" is much like those 3D visual puzzles where at first you see only a noise pattern, but when you hold it at the right distance and let your eyes refocus a certain way, a picture leaps out at you.
Not sure if we're gonna release the code but was written using django/mysql. I don't remember how much code we wrote. I'm guessing something in the area of 10k lines.
Actually, I find it perfectly comprehensible when said aloud with the right emphasis and pacing - it's only difficult to understand when written down with no punctuation.
He's not completely wrong. Human power is by far one of the least efficient ways of powering transportation.

But most people ignore it because people need to eat anyway. And people exercise anyway.
In your lifetime (probably) we've developed and widely deployed the first human cancer vaccine among other things.

I was born in 1985, the year that AZT (the first effective anti-HIV drug) was patented, since then we've developed a whole spectrum of anti-retroviral drugs and turned HIV from a death sentence to an unpleasant chronic illness. The advances in anti hepatitis drugs are similarly enormous.

If you're over 20, then basically any non-generic drug sold in the US was developed in your life-time.

Where the data ends up is not important to its identifier: the reason to have a "logical shard ID" is to provide for sequence and timestamp uniqueness.

The way to think about the problem is that at the granularity of your timestamp you lose the ability to uniquely generate identifiers across multiple nodes (on the single node, this is handled with the sequence number), so you need some kind of identifier for the instance of the generator itself: with UUIDs, they spend a relatively immense number of bits storing the computer's MAC, but if you know you know you only have a smaller-scale deployment and are able/willing to centrally plan identifiers for the deployed nodes, you can get buy with something akin to this "shard ID".

(BTW, note that a v1 UUID need not be generated with a true MAC: the specification both notes that you can just by node addresses from them for a fairly small cost, or to use fake addresses that are marked as such by setting the multicast bit. The result is that if you want to use UUID v1 off-the-shelf with "shard IDs" you are more than welcome to do so, not just in the "analogously-equivalent" sense but in the "to the letter of the spec" sense. You can find more information in Section 4.5 of the UUID specification.)
1980: "Telefuture" - Everything Old is New Again
What we can do (http://en.wikipedia.org/wiki/Aved%C3%B8re_Power_Station) vs what we do most of the time are two different things.

Avedøre shows we can do 91% thermal and 49% electrical efficiency if we set our minds to it. But the fact is that most plants don't do better than 33% at both (because they're not that efficient and because they throw out all the heat).
No, crntaylor has it right: we're supposed to understand that James wrote what he did because it had had a better effect on the teacher in the past. That's how you can justify squeezing that one last "had" in there.
Nicely laid out, of course the "coolness" thing here is that the marginal cost of getting additional cargo is $25 - $30 per gm. Less if you can go with a non-returnable module.

But the thing that really gets me excited is that "you" being the person trying to get stuff into orbit, not having to go to NASA or Boeing to do so. If the only thing between something on the ground and something in orbit is a well defined amount of money, it is possible to compute the ROI for sending something to the L1 point for example.

We consulted a few small companies. I'm not sure I'd categorize the companies as startups hoping to be acquired. They had been around for a while and made money. I think many companies lease machines so the need to track those assets didn't exist.

We were in the middle of working on an iOS app for users to scan stuff around their house and we'd lookup those items to add to our inventory list. When we decided to pivot, we wanted to use that scanning functionality to scan asset tags. Obviously, we didn't pursue it any further but we were heading in that direction.
First we need to fix regular passenger rail in this country. As long as interstate passenger rail is controlled by the Amtrak monopoly, and its attendant unions, rail travel in America will continue to fall behind the rest of the world. There's not even regular rail service between most major US cities 3-8 hours apart, even though tracks exist and demand would exist if trains ran as fast as driving.

Trains are substantially more efficient to move freight. I don't think that self driving trucks will be able to compete insofar as bulk movement of freight goes.

You'll get both, because they're complementary. Self-driving cars will cut the economic cost of electric vehicles: autotaxis will replace private ownership, and their high upfront costs will be split between many users [1]. Conversely, self-driving cars will push performance envelopes, so the EV's enormous efficiency advantage will be desirable.

[1] The economics DO NOT work this way yet, because batteries degrade too quickly (Tesla is what, 500 charge-discharge cycles?). Heavier use means proportionally shorter life; no advantage. Solve battery life, and you've solved economics.
The $132/g vs $127/g price would make sense, all other things being equal (which are not, ok), if SpaceX were pricing in a duopoly, right?
We'll certainly have electric cars on a substantial scale by 2033, and it's likely we'll have self-driving cars deployed in some significant contexts (long distance freeway travel) by then.

Social forces will drive the former, economic forces will drive the latter.
In more ways than one. It's taken decades if not centuries of study of other diseases to understand them and to develop treatments, and just as much time for treatments to have an impact on incidents of the disease. The study of HIV/AIDS has really shown off how far modern medicine and medical research has come. We were able to understand the disease in a matter of years, and develop some crude but effective treatments almost as quickly. Today HIV has become a treatable chronic condition, though the treatments are costly, and vaccines and cures are being developed as we speak. It's really quite remarkable.
In my Portuguese class we were given this ambiguous phrase as a riddle:

"Maria toma banho porque sua mãe disse ela traga a toalha."

We had to make those words make sense only by adding punctuation and without changing the order of any words. Can you figure it out?

For those who don't speak Portuguese, the phrase above translates to: "Maria takes a bath because her mom said to her bring the towel." Doesn't make much sense!

The trick is that "sua," which means "her" when the following noun is feminine, is also the present third-person singular of the verb "suar," meaning "to sweat." Thus, with a few commas and quotation marks, it suddenly makes sense:

Maria toma banho porque sua. "Mãe," disse ela, "traga a toalha."

=

Maria takes a bath because she sweats. "Mom," she said, "bring the towel."

Not nearly as ambiguous as the "had had had had" example, but a similar lesson regarding the need for punctuation.

Edit: as personlurking pointed out, suar is "to sweat," not (as I put originally) "to smell." Thanks for catching that!
The stoplight indicator and a few other things were done via client side js with non obvious variables names. Once that Greasemonkey script came out it was quickly moved to the server side since there was no reason not to do it there. I believe it was just on the client side due to ease of development when it was being built.
In terms of environmental cost (not just CO2) a bicycle is actually 3 times as expensive as a really good car: http://www.thetruthaboutcars.com/2011/09/is-a-bicycle-really...

And if you put 4 people in that car, it wins easily, even with a somewhat more average car.

People like bikes mainly because people eat and exercise anyway, so they might as well do some useful work for it. But purely from the environment, and assuming people only bicycle for need, not exercise, it's not an automatic win.
Meanwhile your customers are getting DDOS'ed while you are faffing about.

Yes, I fully agree that for things like software and standard network maintenance the above is good. But as someone else mentioned in this thread. DDoSes that require quick resolution put you between a rock and a hard place in terms of doing things "right"
I remember my statistics lecturer was fond of pointing out that NASA estimated the probability of SOMETHING failing on launch was (1). That is, because of the complexity of the project, there was always something that was missed or broken - although it could have been as simple as a bulb that was backlighting a switch might be blown, or a cupboard might have been restocked incorrectly, or a calculation for external events might be slightly off.
I think the 'fail fast' strategy shown here is a pretty good one, freeze as soon as anything is outside normal operating parameters to give you time to decide what to do (I can see Elon Musk standing over a control panel with 'Abort / Retry / Ignore buttons').

The other things that helps is to have many redundant parts. So far they've been able to steer clear of any catastrophic mishaps but given the nature of spaceflight it will be a long time before we can relax on that front. 10's of launches without serious mishap would be quite amazing, so far the statistical base is rather thin. That does nothing to detract from the achievement to date, SpaceX is nothing short of incredible.

Curious to hear feedback on how to handle pricing for existing customers as you evolve your pricing model. The KISSmetrics guide recommends grandfathering in existing customers which makes sense. Are there opportunities to allow them to help grow your customer-base by inviting new customers into their discounted pricing tier, and is that generally worth it, or should you avoid the complexity involved with managing such a broad range of price structures?
In addition to your point, high speed rail can also carry cargo as well as passengers.
Shuttle mission STS-51 suffered an engine failure but still completed successfully (although at a lower than intended orbit):

http://en.wikipedia.org/wiki/STS-51-F

STS-93 also shut down an engine (although not as dramatically):

http://en.wikipedia.org/wiki/STS-93

The answer is really: yes, minor issues happen all the time. Something as dramatic as an engine shutdown (as in CRS-1) is rare but not unheard of.

With Falcon9/Dragon -- none of these issue have resulted in failure to reach orbit or complete main objectives. If SpaceX weren't under such close scrutiny, we probably wouldn't notice the issues Dragon had on this mission.
A friend of mine tells a story that's about as close as real life gets to this kind of language trick. He was helping a friend in college study for her Test of English as a Foreign Language. She was working on past tenses and, sincerely attempting to explain a mistake she'd made, he told her: "If you had had 'had' here, you would have had to have had 'had' there as well." Whereupon she screamed.

Freight is a big problem. They own the rails; Amtrak is a guest.
From years of debugging, I know I am unconsciously biased towards the view that a bug in my code or hardware is the result of a very low-probability event, and strangely biased away from the view that a medium or high-probability series of events occurred for which I didn't perfectly plan.

It always turns out to be the latter.

Therefore, I will predict that this event is NOT a low probability double-bit error brought on by stray radiation that bypassed all safeguards. (Unless those NASA guys are superhuman designers, which I guess could be valid hypothesis.)

37 years prior to 1976 was 1939, when none of the interstate highway system was built. By 1976, it was largely in place as we know it today.

The Ataris had this capability before the Commodores, without the crashing. They were designed to scroll entire screens of material almost effortlessly from the beginning. When you combined it with the redefinable (and color) character sets, you could put a scrolling map of Europe in a few K of memory.

Ataris had coprocessors for 256-color graphics, sound, I/O, and intelligent peripherals. You could mix text and graphics modes on the screen line by line. They had hardware sprites. The 800 (and its successors) even had an S-video output. All in 1978.
> A vaccine is not a cure. It's prevention

True.

My point was that the title of the post indicated that the child was cured. We don't know that yet, and may not know for some time. It will be nearly impossible to eradicate HIV without prevention. If this child has unprotected sex as an adult thinking that it is cured, is that safe? We don't know. Maybe the virus will show again in their adulthood.

However, if a vaccine is found and we can prove the vaccination works, that provides a lot more security. Because of many of our parents getting vaccinated, Smallpox got to the point where their children (us) didn't have to get vaccinated. That is where we need to get with HIV. Because of AZT, etc. people just assume it is more of an annoyance now, like Herpes that can be managed. We need adequate resources dedicated and I am concerned that touting a cure that may not be is not in the public's best interest.
The Tyranny of the Queen Bee
One has to wonder if the infant is homozygous for the noted CCR5 variant that confers resistance to HIV infection. This could potentially explain a high viral load with negative titers later.

I can't tell (from the relatively scant details) if the child ever developed HIV infection, by which I specifically mean to include infiltration of a cell by the virus, replication, and a host reaction. I can't find text in the articles describing which blood tests were done on the child. If her ELISA and Western blot are negative (still) but she initially had a nucleic acid amplification test that was positive with high titer, then it would make me wonder if the drugs, for this baby, were not necessarily the key element causing her to be disease free. I.e., I would wonder if the infant weren't actually cured because she was never fully infected in the first place.

If she was truly infected and her body was reacting to the replicated pathogen, then this early treatment strategy is extremely interesting.
This is from a few weeks ago and is basically one guy's fantasy based on not much facts. The real current plans are much more about small regional networks that connect places people want to go rather than rail geek porn that just connects everything because it looks nicer on the map.
My understanding is HIV is still more or less a death sentence, with the antiretroviral therapies being relatively effective to push back the final outcome. And there are issues not being discussed here, such as compliance issues with the treatments (adverse reactions and so on) that make patients drop the treatments. It's far from being perfect yet.
Malaria hasn't been cured but we have much better anti-malarial drugs now.

Same for HIV.
Well, labelling someone as mentally ill is at least a step up from the people the believe stuff like, "I was depressed once, but pulled myself up by the bootstraps, therefore all this depression stuff is a bunch of hogwash!"

I think you are wrong about that. Apple shipped the iMac starting with USB v1.1 in 1998 [1]. It was the first Mac with a USB port. USB was developed in 1994 from a group of seven companies Compaq, DEC, IBM, Intel, Microsoft, NEC and Nortel. [2] Windows 95 that was released in 1997 had built-in support for USB devices.[3] The market share of Mac at that time was about 4.6% [4]. So no Apple wasn't the first computer to ship with USB support nor was it the reason USB went mainstream.

This is a very nice initiative!

A question: as a non-american, in view of America's current levels of paranoia, does this really have much potential beyond, say, bike-racks and street-lines?

I'd love to know, for example, which areas are served by fibre, which have a high numbers of wireless communication towers, which are serviced by new (as opposed to ancient) utilities? I can imagine some bureaucrat deeming many game-changing datasets as "security risks".

If that's true, then what's left to publish?

I'd also like to know, what commitment is there to keeping datasets updated? My guess: GitHub makes this much easier. For example, how long before hundreds of privately owned bike racks get added? How long before pathways get crowd-sourced into the data?

We'll see.
Yes I remember the 90's and how scary it was (the idea of contracting HIV). I wonder how children born in the 90's see it and whether they still view it as we did when we learnt about HIV and Aids in the 90's.

I also remember as a kid the news when Magic johnson made his announcement and thinking , dam he is gonna die really soon, not knowing that decades later he is still doing well.
They just don't make the news. HIV is a very hard virus to fight by its nature, and it's only been around for a few decades, but even so progress has been amazingly fast.

Also, HIV is one of the few highly lethal epidemic diseases that continue to exist in the developed world so it receives a lot of attention, however a lot of progress is being made on other fronts.

For example, the HPV vaccine is a big deal, and should lead to a massive decrease of cervical cancers (largely caused by HPV infection). Also, the Varicella vaccine has been added to the standard "MMR" lineup (now MMRV). It's hard to get excited about wiping out "chickenpox" but the vaccine should reduce the incidence of deaths due to complications related to infection in children and especially in adults, as well as shingles and other illnesses related to infection. Rinderpest, a disease of cattle and some other ungulates, has been officially wiped out as of 2011. Additionally, several malaria vaccines are now in clinical trials. If they prove effective it could easily save millions of lives per year.
