Could you elaborate on that? I think this is just a case of the Lua authors being too academic to let implementation details mess with the semantics too much. They say that there is lots of tradeoff involved but they only mentioned using simpler dynamic typin instead of sophisticated static typing and a very barebones module system.Keep in mind that they don't have to compare with other existing implementations like the Common Lisp example though.

That said, Lua has evolved considerably over the years, specially the embedding API (I belive it has been completely redesigned more then once). Sometimes thery added changes that made the API simpler (for example, globals used to be accessed using special functions, now they use table lookup, as mentioned in the article). Other times, things were originaly limited due to the implementation, but they got "cleaned up" in latter versions (upvalues gave way to proper lexical scope, "tags" became a more general metatable system, etc).
I think even that is a great idea...albeit with a much smaller market capability than what airbnb is now.
Nothing will speak more clearly than the results, so I can understand some skepticism.

I'm the lead instructor for gSchool, Jeff Casimir. I've been teaching Ruby since 2005 and started Jumpstart Lab in 2009. I have both more classroom experience (total) and more hours spent teaching these technologies than anyone in the world.

I wish there were dozens or hundreds of people learning these skills by themselves on the web, but it's just not happening fast enough. The talent shortage is the #1 problem facing most small software businesses, and there's no fix in sight. This is just our little contribution.
So what have you changed your career for ? A job relating to programming, or something completely different ?

Presumably their #1 priority can be specified in a more rational way without random worshipping of some old document? Other countries, not blessed with the Constitution of the USA, also have intelligence and law enforcement agencies.

Unfortunately, that is how you know if someone has gone off the deep end.

I agree though that we should all be encrypting communication, but our government helped develop the methods of encryption, and some methods have been known to have backdoors: http://www-cs-faculty.stanford.edu/~eroberts/cs201/projects/...

Why it is highly recommended not to implement your own encryption method, we shouldn't be using something that could easily be decrypted by the wrong people either. We need to study methods that we use extremely well, and be aware that encryption susceptible to decryption via brute-force with significant resources are just as dangerous as backdoors.

I also advocate development of wireless mesh networking technology to handle larger adhoc networks. While those that wish to spy could still become a member of an adhoc network, it would significantly complicate things for them.
Agreed 100%. There's a big difference between a developer with a big heart and a developer who actually knows how to teach.

Teaching, just like programming, takes a ton of practice. I spend four years in the classroom, another two coaching teachers, and have been running training classes for Jumpstart Lab since 2009. I don't think I'm a gifted teacher, I've just practiced more than most.

Frank Webber, who's joining me, spent a significant amount of time teaching a year-long course at the University of Washington as well as spending time 1-on-1 mentoring other developers in Seattle.

Steve Klabnik has spent a lot of time with me co-teaching private training sessions and spends a tremendous amount of time "teaching" online through open source work.

It's just a matter of understanding the methodologies of teaching and a bunch of practice. We've practiced more than anyone else.

No. The Constitution defines the proper form and responsibility of American government. If the Constitution falls, we no longer have legitimate government. That's historical fact.

Other governments' law enforcement agencies follow the laws of their own countries (or don't). Are you saying they shouldn't do that?
"We've tried them all, and found nothing replaces a good old fashioned external hard drive as a backup tool. Online backup services try to "analyze" your data, reorganize it, and sometimes make mistakes."

This doesn't make any sense. Our online backup based on a rsync, makes a copy of the information that you point it to, and save it to a remote location.

What kind of "magic" do they use?
They don't resolve the problem of doing the backup yourself...either.

Having a CS degree is going to be a tremendous advantage in a program like this, for sure.

But I'm guessing Bart, like me, has interviewed kids coming out with CS degrees who just can't program. To be honest, it breaks my heart. If you complete a four year program and can't program FizzBuzz in a language of your choice then you have been completely bamboozled. I would not have believed this possible until I saw it myself.

If we're going to measure things in GDP, I believe that the disparity matters more than the hard numbers

Matters for what? For looking at absolute wealth, it doesn't matter at all. Africa's GDP now is higher by a factor of almost 4, according to that Wikipedia page, than it was in 1820. The fact that Europe's is higher by a much larger factor doesn't change that.

For analyzing root causes, yes, the disparity matters a lot: it tells you that the "first world" has done a much better job of making people richer. Which might lead one to think about what that huge increase in GDP is built on. Perhaps a desire to have something more than bare subsistence, combined with an understanding of the kind of economic, social, and cultural environment that's needed to make that happen?

There's another factor too: if you just have a plot of land that is able to provide food, water, clothing, and shelter for yourself without any actual registered trade you actually contribute nothing to the GDP.

And you are also at bare subsistence level. Yes, you are providing food, water, clothing, and shelter for yourself; but you are providing nothing else. If you're satisfied with having nothing but the bare amount of food, water, clothing, and shelter necessary to sustain your life, then I guess you'd be OK with that. But if that were the case, how would you be able to post here?

My understanding is that this self-sufficiency was basically destroyed by colonists.

No, it was changed by colonialism from bare self-sufficiency to the ability to export large quantities of food and raw materials. When colonialism ended, all the infrastructure needed to continue that level of productivity was still there. The post-colonial governments squandered it.

I have a hard time believing that for the percentage of the population living in "extreme poverty" (less than $1.25 per day - note that dollars and cents matter more when you don't have other ways to provide for yourself), things were as bad when they had their own land and were self-sufficient.

You and I can't make this judgment. Only the people themselves can. As yummyfajitas points out, many of them appear to be opting for modern conveniences over bare self-sufficiency. That indicates to me that if they were dropped into the same circumstances as their ancestors in 1820, they would not be pleased.
While I generally support what is being proposed here, Google as a company has a strong interested in "keep[ing] the Internet free and open" for them to sell their products. That doesn't make it wrong, it just means that if this was raised by organisations that don't have a clear commercial interest then it might improve the visibility.
After thousands of wars peace is understood by everybody, not so about the free and open Internet, which to most is something that just works like electricity, or black magic.

Making more people understand is definitely worth one tweet.
Wow. Getting divorced seems rough enough already; sucks to be judged unemployable on top of that.
Your argument is a non sequitur: states are necessary, therefore states are not systems through which coercive force flows.

I did not say that at all. I am OK with states being systems through which coercive force flows, because I think channeling and supervising said force usually results of less of it flowing than otherwise would.

Can you imagine a state that doesn't wield violence? That's what a state is.

It's hardly the only distinguishing feature. States also build infrastructure, promulgate laws, provide forums for resolution of disputes and so forth. Your argument as made here is both narrow and immature.
Ask HN: Review My Startup, UnloadYourCar.com
Would like to get feedback from the HN readers.

I have founded UnloadYourCar.com. This service helps you get the best price for used car. [Think Gazelle, eBay and Lending tree for cars.]

Primary User: General Car Owners
Primary "Customer": Auto Dealers

Enter your car and mileage then up to 20 dealers or private buyers make you an offer. You choose the best offer and get a voucher commencing the agreement.

No hassle going to multiple dealers or time spent posting to all the websites.

Revenue: our primary revenue would come from dealers paying to "bid/advertise" their offer.

Right now, automotive dealers are paying on average $20+/unqualified leads (Autotrader, cars.com). (Personal experience)

The Advertising and Marketing costs per new vehicle sold are $650 (NADA research).

I believe we can command a higher price $250+/lead (after validating consumer use/demand) because this is a "Qualified" Lead/Sale for the dealer.

Competition:
Atuotrader, TrueCar, Cars.com, etc.

Insightful. I'm curious as to what you think are the basic human rights and the principles of the Enlightenment.
Agreed. Tandy Color Computer 2 for me (with Extended Basic ROM upgrade - Oh Joy!), but same deal. Natural transition from there to QuickBasic (not QBasic!) running on a 386SX and the world of compilers and runtimes. Between QuickBasic and Python there was a blur of other languages which I have mostly forgotten.

But were it now for the REPL, I would likely not be a programmer today.
True.

A one-time pad as a consumer encryption has yet to be realized though, even though the programming effort needed to create a system like this is low. It's even easier to use such a system in todays world of 64 GB USB drives. (64 GB could be used as a key for almost a life-time of text correspondance.)

What the public would benefit from is a system that works as follows:

- Program has a create key mode. Lets you specify key size, or use the rest of the capacity (eg. a full thumb stick).

- Creates two of these files (one for each participant).

- Has a simple interface for encrypting/decrypting content
based on the key file.

- Each message is prefixed with the offset of the file

- Party 1 starts at the beginning of the file. Party 2 at the end of the file. In order to avoid resending data using the same offset. When they get close to overlapping in the middle, they create a new key.
MySpace had a very significant mindshare among a similar population segment. IIRC it wasn't obvious until ~2006-07 that they would be overtaken or that the relatively superior UX of Facebook would matter so much. Looking back now, having been on both, MySpace had an uneducated feel to it that was somewhere a little bit higher than Youtube comments but not by much -- chain letters, trolls, fake profiles, random friend requests and ultimately a lot of spam -- these were things that all made FB shine by comparison as a college-only network (it came to Berkeley ~2004-05)

But certainly by that time, "ordinary" people were already primed for online social networking. I agree that this doesn't quite extend to GeoCities though.

Yup, that's how I usually picture it, change the values to a collection of sin and cos functions.

When I started explaining it to some computer science students, it helped by giving a particular example of its usefulness:

Sound is composed of waves so, when you want to send a music to a friend it's all a bunch of values like [0, 1, 2, 1, 0, -1 , -2, -1, 0, ...]. If you know they're going to look like waves (sinusoidal functions) why not just send your friend how much they look like sin or cos? The values back there were just a 2sin(x) so why not just send them the value [2]?

You could save a lot of bandwidth. You just need to "correlate" sounds with a bunch of sin or cos functions everybody agrees on :)

Bonus: you can add the phase values, 2 sin(x + phase), to get the beats just right.
> It's not surprising

Being "not surprised" seem to be the new meme on HN. Anyway, let me disagree: when you know how to write words in a sentence, you do it well under any circumstances. (I forgot its name but there is a story of this British poet whose one-sentence instruction sticker on how to handle the toilet flush was such a precise and cristalline piece of prose)

So no, if academic papers are so poorly written now compared to manpages or academic papers centuries ago, it is because academic people are worse writers.

And at a community college you can qualify for traditional student loans, GI funding, etc -- making the equation a lot easier. If you know of anyone who's completed one of these programs and is now a full-time developer I'd love to meet them and pick their brain.

Having taught at Boston College's Center for Digital Imaging and Arts (CDIA), I was not impressed with the curriculum and, most importantly, the expectations for students were disappointingly low. It was more of a "pass the time, get the certificate" than a genuine learning environment. I hope it's different here in Denver.

Even using encryption that is trivially defeated is effective at resisting broadly applied surveillance as long as the fact that it's trivially defeated isn't public. That's because you need to restrict the application of the technique to a rather limited circle to maintain secrecy, which more or less guarantees that it's only applied in a targeted fashion.
In this context sender = source IP address, so P2P can only make you pay more.

I think I've seen this before... I think the idea is, some transitions between particles (decay paths etc) don't work. The structure of the paths that are allowed match up with codes that are "correct" in an ECC algorithm. In ECC, if you get an invalid code, you can correct it to a valid code. I can't think what the physical analog would be - if a particular kind of transition happens, it gets "corrected" by the Universe to a valid one?

People who seem successful from the outside, are in general, very hard working and focused in their venture. I have few friends from high school who always got good grades and understood topics very fast. Being around such gifted students made me feel insufficient. I could never compete with them no matter how hard I tried. In my mind I was trying hard. Turns out, while I was slicing my waking hours between sports, hanging out, studies and socializing, they invested all those hours to study class materials, read supplementary materials, reading ahead for the class next day. To me, sports, studies and friends were equally important while they kept single minded focus on where they want to put their hours. It also turns out, the method is replicable. You can put single minded focus on anything and be reasonably successful. I believe it. Because I have seen it happen in my life. Albeit, there are talended people and hard work will always fall short of talent + hard work. But hard work will get you far enough.

Distributing a OTP encrypted ciphertext ahead of time doesn't accomplish anything because the ciphertext can be translated into any plaintext you want by choosing the correct key.
The DOM is not being heavily abused; it's just a canvas element and nothing else. The demo is so CPU intensive because the code is drawing the rasterized image pixel by pixel on the canvas, instead of relying on the GPU and using WebGL which would, AFAIK, result in much better performance.

One positive effect of doing this is that the code is _very_ portable and doesn't require any crazy feature in the browser or the PC (for example, i'm able to see the demo on my work computer even though WebGL doesn't work on it because of lack of drivers).
I'm not sure how indicative that is, but I have never heard of CarWoo. So that wouldn't make it very clear to me.
