Well said. I've been using Groovy heavily for the past year and a half or so, and have been thrilled with it so far. We're using Groovy on Grails for a significant portion of our startup project, and it has worked out very nicely. It's far more productive than plain-old-java, but it is (mostly) dead simple to learn and use for someone coming from Java.

Is Groovy better or worse than, say, Clojure, Jython, JRuby, Scala, PNuts, Fantom, Ceylon, Nice or Gosu? I don't know, but I know that - compared to Java - Groovy has been a big win for us.
I see what you're getting at, but I wouldn't call that "using stealth". Surely the demolition of one observation platform isn't going to raise an eyebrow.

You're forgetting that holes in your observation cloud open windows through which my drones can beam waste heat. Of course I wouldn't be trying to destroy just one drone. The point is not so much to divert, as to cause you to reveal your resources and to give mine more opportunities to use stealth.

Also, the scenario here is not the invasion of a solar system. I thought it was the control of a particular resource like an asteroid. But if you want to play "invasion of the solar system" then I'm game.

It makes more sense to use drones for reconnaissance, and then just go at your opponent with a bigger fleet.

Only up to a certain point. If you create a tremendous concentration of resources and industrial output such as an awesome battleship, you might have something that can beat any individual craft in a 1 on 1 battle, but you've also created an opportunity to hurt your side a lot with only a very small expenditure on my part. This is especially true with stealth.
I'm not seeing how your solution is "far better" considering that the "iPhone of similar vintage" is the iPhone 3GS (released June 2009) which still continues to receive updates.

I agree with your last statement completely.

Here are two more tidbits about the Concept One:

Dvorak. One thing that was rather odd for me was that while I was learning the Dvorak keyboard and for a short time afterwards I couldn't touch type on QWERTY anymore. Then one suddenly, about six months after, it came back to me and now I can touch type in both layouts. It's almost as if the 'QWERTY typing center' of my brain had to house two layouts for a while until Dvorak got its own place.

Adding to that observation, during that same time period I could almost feel my synapses firing faster and new neuron connections being made. I felt like I got a turbo boost to my IQ during that period where I thought fast, was more creative and just generally sharper. That effect, whether placebo or otherwise has completely disappeared by now, so it's nothing intrinsic to the format.
"""It's not a reality based generalization though, it's unfounded nonsense - like the thought that black people can jump really high compared to white people, you can die if you leave a fan on while you sleep, or that you can identify criminals by measuring their skulls."""

"Completely unfounded nonsense", how? Because, people just don't know enough teenagers to generalize that they aren't in general that motivated?

He is comparing the general teenager with a 16 guy who learned programming on his own, built an app people want to use in hundreds of thousands, and even got an investment for it. It's only reasonable to deem him quite apart from the average teenager in the motivation department. And judging from the success of GTD methodologies and such crap, even from the average adult.

"""All of these beliefs have been shared by millions of people at some time, but that does not make them true and certainly does not make them suitable for reprinting as implied fact by a state-backed, high quality, supposedly objective news organization."""

The reporting that a kid that managed SUCH AND SUCH is more motivated than the average kid, is nothing like Lombroso's theory or some urban legend about dying when sleeping with a fan on. It's a simple observation and statement of fact.

As for the report on the extra politeness of the kid --compared to the average kid--, do you really believe that a reporter cannot spot a polite kid when he sees one? Or, do you think that he hasn't seen enough kids in his life to be able to discern any difference in politeness levels?

(Note: I've worked as an teacher for a spell, and I know that there are kids that are far more motivated than the average kid, and kids far more polite than the average kid. I also know one when I see one).

And I count that to their credit, as I do for the other companies who have fought this. I count it to their credit because it is no credit to resist a temptation not offered to you; my opposition to SOPA is easy, because I do not stand to gain from it. They are actually resisting something. But the answer to the question asked is, even if it appears to harm certain other companies, it's still to their benefit if it harms others even more, and that's why we're not hearing from them very much.
Now that I think about it, I do think that I heard somewhere that the free AI class has a final project. IIRC, it's a "challenge" that is the same for every student, and the solutions are ranked by how well they solve the problem according to some metric that can be measured automatically. Kind of like how Netflix set up a challenge like that with a million dollar prize, only in the AI class there was no cash prize. (I hear that they did send out requests for job interviews, though, as rewards.) This actually sounds like a great idea to me. Topcoder for AI. I'm sure something similar could be devised for the Machine Learning class. Now that I think about it, I'd actually be pretty surprised if they don't do something like this for future versions of the class.

I've heard some people complain that the programming assignments in the Machine Learning class were too easy. A specific complaint is that they provided all the equations and explication you needed right in the homework statement rather than having to remember it from the lectures. Personally, I find this approach to be the best way to learn. My favorite approach to learning has always been "workbook" based, where the lessons and problems to solve are in self-contained lessons. Give me material like that and I can learn anything. There are entire classes at MIT that I did extremely well in because they were workbook based. And I took Organic Chemistry and got an A+ in the first half of the class because it was workbook based. They thought I was a genius. Then the second half of the class used the more traditional approach of reading 100 pages a week of terribly boring and dense textbook. I got a D- in that half. Fortunately, it averaged to a C and I passed the class, but if the entire class had been workbook based, maybe I'd be doing something great with Computational Chemistry at the moment.

Back to the actual ML class, I've only completed the first few programming exercises as of yet, as I was also taking the database class, which actually turned out to be a lot of work. I've heard that in the ML class, the programming exercises become progressively spoon-fed, and ultimately not much of a challenge. That's not good, if true. While I do think that all the information you need should be at hand, you should still be given challenges that make you think. All the thinking should not be done for you.

In edit subscriptions you can do an OPML import. I had the same first thought.

What is broken though is they don't seem to support folders.
While making a sweeping statement about such business models not working, I guess the op failed to take notice of Gazelle.com, which has been in operation for 3 years now, has raised $46.4M in total with the last round being a series D of $22M. And guess what their business model is, arbitrage on used electronic products. So safe to say, such models can and do work.

I also believe that these models will increasingly become more mainstream, because they save people 'time', time which is increasingly becoming the most precious resource that we have. You save 2 hours of time for someone, and pay him $40-50 dollars less than craiglist or ebay, and I am sure you can find a large percentage of people for whom the opportunity cost of 1 hours is more than $20-25, and voila, you have customers.
Much better.

I believe the proper Latin phrase, to evoke appropriate pretension and bravado, would be prima facie.
and what is that incentive? there's no extended office space, mentor-ship, or support network, I was working with George on this, but we felt like it got slipped out beneath us when we tired :/ I agree with Herval that this could have be executed better, but more accurately that if these complaints don't exist the program will not improve (though many are extreme.. along with zac's comments :p )
A Monadic Pratt Parser in F#
While I completely agree that what I said would be a red-flag in the wrong context, this was more a case of - I believe Clojure is a better tool for the job and I don't want to join the team if we're going to be stuck with Java. My statement wasn't about wanting to do future development with a specific language, it was about wanting to use the best tool for the job. We actually use Clojure, Java, Bash, Ruby, web (HTML+JS+CSS), and C#...
This has nothing to do with playing fast and loose with data types, and everything to do with implicit conversions between data types. This code would work just as well in a fully statically typed language with the same conversion rules.
An interesting technique - construct requests that produce pathological hashes (which degrade to linked lists, which have O(n^2) insertions). Make it big enough, and you tank the server. It may be useful to note their link to a previous article, which implies this has been known since 2003 in Perl.[1] Any news of actual attacks using this technique?

The great part is that, as long as you convert request params into hashes (a reasonable step, I'd imagine the vast majority of web frameworks do this), you're screwed if your language is vulnerable to this. Of course, you can tweak your framework to not use native hashes (or detect such attacks and handle them separately), but that's not generally an option as it's a pretty involved operation.

I wonder: would a hashtable that uses cuckoo hashes be vulnerable? Technically, sure, but would it make the attack infeasible due to the difficulty in creating double-collisions? Or is that not as hard as I'm thinking it could be?

To quote George Carlin (RIP):

Now, if you think you do have rights, I have one last assignment for ya. Next time you’re at the computer get on the Internet, go to Wikipedia. When you get to Wikipedia, in the search field for Wikipedia, i want to type in, “Japanese-Americans 1942″ and you’ll find out all about your precious fucking rights. Alright. You know about it.

In 1942 there were 110,000 Japanese-American citizens, in good standing, law abiding people, who were thrown into internment camps simply because their parents were born in the wrong country. That’s all they did wrong. They had no right to a lawyer, no right to a fair trial, no right to a jury of their peers, no right to due process of any kind. The only right they had was…right this way! Into the internment camps.

Just when these American citizens needed their rights the most…their government took them away. and rights aren’t rights if someone can take em away. They’re privileges. That’s all we’ve ever had in this country is a bill of TEMPORARY privileges; and if you read the news, even badly, you know the list gets shorter, and shorter, and shorter.

Yep, sooner or later the people in this country are going to realize the government doesn’t give a fuck about them. the government doesn’t care about you, or your children, or your rights, or your welfare or your safety. it simply doesn’t give a fuck about you. It’s interested in it’s own power. That’s the only thing…keeping it, and expanding wherever possible.

RSS isn't ever going to be a big deal. If you are thinking in terms of market size it's never going to be really big. Facebook, and Google+ have both taken the subscription model in a direction that is more consumer friendly.

If you accept that premise, you are building a product for informed, longish-term computer users, and you are treating them like they are beginners. If my intrest was piqued by RSS I probably already use an RSS reader, and have a bunch of feeds I want to use.

You are missing the ability for me to organize my feeds into folders. I have a lot of feeds, and I need folders to triage my reading into a sliding scale from important to least important.

After all of this keep it up, because I am, and I think many others are, willing to pay for an app that does RSS reading well.

This isn't coming. A decade ago Sen. Fritz Hollings (D-Disney) ran a bill that outlawed general purpose computers and made it a federal crime to posses a compiler without a license.

It's long since been here and will continue. Government officials desire the power to act with discretion to outlaw the computers they don't like and tolerate those they do. The especially want the power to decide after the fact and hold you retroactively responsible for anything they choose. The computer industry with its empowerment of the masses and startup culture is especially vulnerable to the usual bureaucratic power games so we will have to fight in order to lose our freedoms more slowly.

The legislators and bureaucrats aren't stupid and they aren't ignorant of the principle of Turing Equivalence. They love the idea that every computer can be demonized and outlawed at once. They especially love the idea that every programmer must hope for the forbearance of his superior in the bureaucracy, forever focused on pleasing the big man in Washington on whose pleasure his freedom depends.

It's like 1984 where Winston thinks that O'Brien will be his ally in reform because O'Brien understands the corruption, abuse, and evil of the system. Winston was wrong. The incumbents will not improve by being better informed. The horror totalitarian future you want to avoid is exactly the dream they cherish.

I'm not berating anyone.

What I'm voicing is neither an objection nor an approval for one choice of technology over another. What I'm saying is that the author of the post, without any admitted experience or knowledge deems themselves so adept as to ask an entire industry segment to abandon the use of a technology without providing any sound logic behind their request or viable alternatives.

I know they shouldn't be using Flash; I've been berating people about that for over a decade. But even so, as a technologist I cannot offer a solution to that particular segment without knowing the root cause of their particular choice, their present requirements nor the necessity of a photographer engaging in a venture that for all I know won't provide them any return or benefit. I find it presumptuous to know what's best for someone else without even knowing the root causes of their alleged problem, especially artists who by virtue of their business model have more to lose than gain by presenting their work in an inferior portfolio format.

There will be some who'll find a solution that fits them best and other who'll keep paying the hosting and update fees until they've become tired and lose interest. It's the nature of the beast. All told, there will be less developers with Flash abilities moving forward and the public will become more educated, so who knows, maybe the problem will solve itself.
Since you asked...

There's only 2 of us, and the other guy also wanted to learn Clojure. His response to my statement was: "That's part of the reason I want you on the team, we need to advance some of the tech on the project."

Also, Clojure has been in use at DRW for over 3 years, so adding it to another project wasn't actually that big of a deal.

I know all that context wasn't in the article, so I think your questions are on point - but, I think that info isn't really on topic for the article, which is why I left it out.
I found the title a bit unclear. The first time I read it, it sounded like Apple was using Debian Squeeze as part of Time Machine somehow, rather than someone interfacing to Time Machine using squeeze. Both stories would have been interesting, I just wanted to know which one to expect.

Yeah, this is really a WPS vulnerability. As far as I can tell, it just brute-forces the WPS pin number (8 digits), and the routers then provide the WPA key as part of the WPS protocol.
It works pretty well in the west coast here. They say that they are using real Macs which is a big plus to get the latest updates for xcode etc.

Also, CoronaSDK, Titanium and GameSalad etc. are pre-installed. Very easy to get started with those, although there are some lags due to screen refresh rate.

Interesting site. I lost interest in Spotify but I can see the novelty of a site like this.

But... your example URL makes it pretty easy to guess at other people's mixes... so not very private. Not that you claim it to be private. But if I was sending a mix to someone and typed in a special message for them, I would not really want random people to read it. Some sort of URL hash would at least make it harder to guess.

"I still think I'm missing something with breaking the record players, but based on my understanding it's a metaphor for incompleteness."

The record player is a Turing Machine interpreter. The "blowing up" is going into an infinite loop, or stopping the record incorrectly when it would have in fact terminated. The record player doesn't blow up if it A: runs a terminating program or B: correctly stops the record by determining the program will never halt. The differing record players represent the fact that you can write interpreters that will detect certain cases of infinite looping, but the halting problem prevents you from catching all cases. The repeated sequence in the book is:

1. A new "guaranteed safe!" record player is produced
2. A record is produced which breaks it (a program that loops but gets past the player is produced)
3. Goto 1.

At least, IIRC, it's been a few years since I read it.
5 Reasons Why Even Home Users Need Data Backup Software
We really don't have to attach design pattern concept in a dynamic language.

PIL.open = lambda filename: PIL.getattr("open_" + filename.split('.')[-1].strip())

so

PIL.open('whatever.jpg') == PIL.open_jpg('whatever.jpg')

We don't do this in C++/Java because object & methods are compiled into address, and you can't concatenate arbitary memory/VM address directly like getattr()

Factory pattern is basically a huge pile of lookup table of if's and switch's, unless you use some clever voodoo in reflection, it's just a bridge to map semantic vars to memory/VM addresses.

Which in a way, is a user-level re-implementation of a dynamic language engine (poor man's version)

> What's the legal status of email? Is it treated as if it were "just like snail mail"?

If only. That would be an improvement. As matters stand, they're much more poorly protected: https://en.wikipedia.org/wiki/Email_privacy

> After 180 days in the U.S., email messages lose their status as a protected communication under the Electronic Communications Privacy Act, and become just another database record.[6] This means that a subpoena instead of a warrant is all that's needed for a government agency to force email providers such as Google's Gmail to produce a copy.[6] Other countries may even lack this basic protection, and Google's databases are distributed all over the world. Since the Patriot Act was passed, it's unclear whether this ECPA protection is worth much anymore in the U.S., or whether it even applies to email that originates from non-citizens in other countries.
Agreed. Over the last 10 years, arguably much longer, if you take into account the "war" on drugs, the US government has begun to, in some aspects, wage war on its own citizens. The power grabs by politicians and law enforcement nowadays is reaching insane levels to the point where I am not confident that we live in a fully "free" country anymore and to where I think that people doing things like this could be one of the only defenses against our country going even further down the shitter. Just as our government is fine with killing plenty of innocent people in a variety of ways (non-militants killed in wars, overzealous law enforcement, people executed that are later exonerated) I am fine with some innocent "casualties" when citizens fight back, which in this case is the loss of privacy for some of the people who sent these emails.
