And some people might not like to hear it but Oracle has really provided a new injection of excitement in the JVM with their G1 GC and JRockit additions.

And with clarity around the future roadmap and the ever growing list of non-Java languages the platform has never looked better IMHO.
We are couple of graduate students who implemented an end-to-end IPv6 social telemetry platform as a lab project last semester. We have a meter that is connected to the lab's coffee machine and refrigerator. The web interface [1]
can plots the energy usage of these devices. We decided to make the data public to help evangelize the importance of being able to live monitor the energy usage of one's appliances. In fact, we encourage you to go check out the website and you'll see a live plot with spikes whenever we brew coffee!

We also implemented an Android application that complements the user interface, and plan to expand this project further by installing more meters.

Details on the project are available at [2]

Coming from a Python background, I would love to know some more details about Perl's benefits. Are these benefits due to a good testing culture that can be learnt by other communities by sharing best practices or are there certain unique testing Perl libraries that are not found in other languages?

Wouldn't facebook benefit from just starting to rewrite parts of their infrastructure in a language more suited to their scale, like twitter did with scala? I can't help but feel all this effort into bending php into corners it was never meant for is not helping them in the long run.
Are you me? :) I used to do this exact same thing in the exact same age range.

This was in the 90s though - what I still regard as the Golden Age of Flying (tm), and the Unaccompanied Minor service offered by most airlines was absolutely fantastic. You would be under constant supervision in the airports, get access to the nicer lounges.waiting areas, have priority for boarding/disembarking, and be generally treated like royalty.

Even if you were flying coach/economy.

It was totally brilliant, and I was heart-broken about losing this aspect of flying when I turned 16. (IIRC that's the age limit)

Come to think of it, the reason that UA screwed the pooch so badly on this could be because of the death of the Golden Age of Flying.

I, for one, have never had to "sanity check" my word processor/text editor against my inputs; the letters and figures appear in pretty much the same order even if the glyphs are different because, regardless of the mechanics of the writing, in the end it's just me putting characters into the system one at a time.

Those who cannot do calculation at least well enough to do estimation have no idea if something has gone wrong, or where it might have gone wrong, when they see a result. In that regard, it is less like failing to learn to write currently (cursive simply means slanted, not connected; current comes from the French "courant, or running*) before composition and a lot more like failing to learn to read. I do decibel (common log to one decimal place) calculations in my head not because I feel the need to exercise arcanities I learned when four-function calculaors cost hundreds of dollars, but because it allows me to spot errors in mechanical/electronic calculations (including those in the analog realm) quickly. When you rely entirely on the machine, you have no way of knowing whether or not the machine is sane.

When I saw the use case of a couple settling down to look at a (likely non-HD) video... of large paintings... on a 10" display... from a robot... that you have to drive yourself... - well, I laughed. Yes, it sounds cool, for all of about five seconds, until you realise how irritating it would be. Presumably it wouldn't be free, either.

One could argue that this would be great for disabled people. Maybe so, but that wasn't what was shown. However, when they hook up a 360 degree high-def camera and feed it through to a next-gen Oculus Rift VR headset, yeah, then we'll talk.
There are three factors that I think lend credibility in this case:

1) Dalton's founding vision is strongly principalled. This is what will give the company the strength to battle against the temptation to stripmine the value of the company the way that Twitter is doing with their developer-hostile stance.

2) The fact that 10k+ people put down a significant payment up front mean that there is a buy-in and critical mass to the service that mean it will have some value from day one, even just to users, and even if it is impossible for it to completely replace Twitter.

3) The money in the bank means there is both means and pressure for App.net to be developed quickly.

None of that is a guarantee, but I think it's a strong foundation for success.

When you are facebook's scale, there is no off-the-shelf solution. Whatever they choose to do, it's most likely going to be their own effort. There is nothing that bad about the PHP language and the fact that all their developers know it, it makes sense that they keep the language, just change what runs it.
Cool concept! I'm glad to see something like that working. I wrote down almost a year ago a very similar idea (I called it Flow) in a "incubator" project of mine: https://github.com/imdario/lyd/wiki/Analysis

You are of course not truly alone, but you must be unusual.

As an example, consider the upvote/downvote arrows on this site. They have very fuzzy boundaries on my laptop (128 ppi). It almost looks smudged. They are perfectly clear on my new iPad (264 ppi).

This is not surprising, it's 2x the resolution in each direction.

Ultimately I think it comes down to cost. As airlines predominantly compete on ticket price, they'll do whatever it takes to reduce that (outsource their logistics, operations, flight planning, etc.) Hell, Ryanair in Europe make their pilots pay for their uniform. All about getting the fare as low as possible, consequences be damned.
The diagnosis of CS education seems correct, at least. My high-school AP CS course, in C++, seemed primarily dedicated to teaching and then testing an arbitrary grab-bag of C++ syntax and STL features. There is no way that class would have gotten me interested in programming if I weren't already. What did get me into programming was writing scripts in mIRC's idiosyncratic custom scripting language, on my own time.

But I think it's more than the language choice that's the problem. You can make a course into arbitrary memorization in just about any language, though some languages may make it particularly easy. In one nice turn of phrase, Seymour Papert quoted a student contrasting two uses of Logo: "In the summer, we learned to program. At school, they are teaching us to write a program." [1]

The push-back and walkway are usually managed by the airport, the airline doesn't really have a choice in this particular case.
Don't forget about data visualization. The dense display is great for time series work (even a small, 1000-point time series can overwhelm a standard-density laptop display), or for image analysis.

Of course, the great-looking text is certainly a plus as well.
it's a horrible article; besides some PR fluff, the description of the laptop is "it's a completely standard Ivy Bridge ultrabook except with Linux preinstalled." no examination of the bizarre claims about designing for Linux versus Windows or anything like that, just "hey, here's a thing! look at how neat it is!"

With a 14.1-inch HD (1366-by-768) glossy LED backlit display.

My understanding is that laptop manufacturers tend to think of consumers as rather simple types who won't get all the fuss about screen resolutions, hence chucking out 1366x768 as the display standard.

However, if you're going to pitch a laptop at developers, why on earth wouldn't you add a few extra dollars to the price and go with something like 1600x900? Dell seem to be making the same mistake with their "developer" laptop (although I believe Dell are somewhat cheekily marketing the laptop at people who might buy in the belief that's what developers would like to use, not the developers themselves).

Very frustrating. And a very poor show from PC World claiming that this is the laptop of one's dreams.

Obligatory plug: don't care about playing games? The laptop I have right now, a lowly HP ProBook 6450b, is the best developer purchase I've ever made. I only use Linux under a VM, but the support's meant to be there as well: http://www.linlap.com/wiki/hp+probook+6450b

I'll admit it, the disruptor architecture was my inspiration.

I've since put together an in-memory database built on JActor that processes a million ACID transactions a second (on an i7 with ssd). https://github.com/laforge49/JFile

What I didn't like about the disruptor pattern is that it seems to require a lot of architecture, and I like to keep things as fluid as possible.

My proposal is that a high-throughput actor framwork (like JActor) is close to ideal for building vertically scalable server software.

I was considering buying this one last week (it was between this one and a Dell XPS 14). The only pro it has over the Dell, besides price, is the keyboard. I use the pgup/pgdn/home/end keys at the side of the keyboard all the time and can't imagine living without them. I don't understand why Dell decided to follow Apple's lead and get rid of them in favor of the chiclet keyboard with the horrible arrow keys... It's especially strange since they're marketing the XPS 13 as the "Ubuntu for developers" laptop. Am I the only one who feels this way?

I eventually decided to get neither, because this one is quite ugly and rather expensive for what you get, and the Dell has a crap keyboard, has problems with Ubuntu 12.04, and is also quite expensive (though worth the price for the parts). Instead I'm buying a 512 SSD to hopefully make my old laptop feel like new!
Boil away. I also hate the "aren't they quaint" crowd, who think it's a shame that third-worlders buy mass-produced t-shirts these days.

But how many cultures were as driven by the need for pure wealth as Europeans were? If it's a 'human trait', why do we see broad technological development in only several areas?

I mean, hell, if your argument is "Folks in Puno were scared that their house might sink", let me counter with "Fuck it was hard for the masses in England during the Industrial Revolution", and it was the wealthiest nation the world had ever seen to date. England was spurred to improve their lot so drastically because of culture, not innate human nature. That's my point.

Perhaps you're just hung up on the word 'happy'. Change it then to 'content'.

Don't just focus on one attack method. Look for the weakest link in the chain. If you get a totally secure computer system & internet connection, there could be a microphone in your room recording what you say. Easy to use crypto won't help there and only give a false sense os security.

You are quoting from the Psalms there, that's poetry. Have you read these texts from which you quote? From cover to cover and in context? Each according to its genre? Am I to take you literally when you yourself speak of sunrise and sunset?

Your definition of faith mistakes faith for blind faith. Faith itself is based on reason, necessarily, at least that is the view throughout the Scriptures. You are wasting time on a straw man here. To say the two concepts of reason and faith are orthogonal is inaccurate. They go hand in hand. Or would you put yourself against giants?

"Some people, eager for money, have wandered from the faith and pierced themselves with many griefs." - Paul, in his letter to Timothy.

Sure. It has signed and unsigned numeric types with specified sizes, and the "unsafe" module provides some alignment and even pointer arithmetic capabilities if you really need to tell the computer everything.

I'd just except the very end of low level stuff from it, mostly due to maturity and GC issues, so it wouldn't be my choice of language for a embedded real-time situation. If you're talking web server/3D game low-level, it's fine.

To me, go looks like C programmers copied Modula-3, whereas Java was Cobol programmers copying Modula-3...
Watch out for

It may iterate over attributes defined in the objects prototype. The right way to iterate over an object is

I'm not sure about HP's ProBook line, but I'm 99% sure their 15-inch EliteBook range supports 1920x1200. I thought that there was an upgrade option for their 15-inch ProBook range, but am likely wrong on that count.

I'd be surprised if a Thinkpad wasn't an option for full HD as well. More expensive than HP - and often Apple for that matter - but you can't beat the quality.

i'm a bit confused: the bsd license allows you to re-sell someone else's source, binaries, images, etc for a profit. you just have to include the copyright notice.

is that what you're sending the dmca notice about? because you couldn't find the necessary copyright notice? (if you didn't download it, how do you know it's not in the about box?)
Ah that explains what I perceived was a very over-engineered way of measuring the current. I've used several of the clip on readers myself in the UK - trivial install - and in fact several British electric providers have sent out their own current usage displays to customers.

Then again I haven't seen any popular usage of NLM (several apps were trying when I last looked) that can determine how much an individual appliance is costing really simply, i.e. the hairdryer cost $3.12 to run this month. That info could be really compelling and could spin out more ideas but doing this non-intrusive load monitoring sounds rather difficult with your data collection method.
It can go further. Caring can be actively dis-incented. If your caring about a problem causes any disruption to your "normal" work, you will be penalized.

That child you rescued and escorted to their destination or a safe location? That's 30 minutes you weren't "doing your job".

And perhaps you're not authorized to escort children. The liability! Sorry, but we are going to have to terminate you.

When it gets to this point of actively "not caring", it's no longer human nature; it is a contrary behavior that has been actively taught and reinforced.

It surprises me. The upvotes and downvotes are gif images, so all you're seeing is a blown up gif. I'm just in the process of replacing similar triangular gifs with near identical looking Unicode characters precisely so that it will look better on mobile devices that make more use of zoom. And in my experience (on iphone, iPad and Android phones and tablets, though admittedly not the new retina MBP) the current gifs look pretty bad when blown up.

I think you've fallen for a placebo and somehow prefer the blurry resized images to the "pixel-perfect" originals.

Interesting - I hadn't considered that the BSD licence doesn't seem to require the copyright notice to be displayed before downloading - so it could display the copyright notice in the purchased program, and be compliant?

This case doesn't seem on the surface of it, to be completely clear cut. Is there a case to argue that it is morally wrong for them to charge for something that is free, (apparently) without adding value? Perhaps. Legally, though, the case might be different.
