They strike me as equivalently victim-y. In both cases, the industry would count the harm as the full market value of anything consumed by the criminal. Whereas the criminal would argue that they weren't going to be paying anyhow, so the industrial player is unharmed. And for both, there's no problem for anybody if it stays a minority activity, but if the behavior became a widespread norm it would destroy the industry.
Wow, this is an excellent idea.

I can imagine building and ordering spare parts for defective and unsupported electronic devices that would prolong their life.

I can also imagine experimenting with building and fiddling with guitar pedal effects from the slew of existing schematics on the Web.

I think the hardest thing for me is going out finding and buying the parts. Some times I might have the time to assemble them but most of the time I wouldn't.
Ha ha... guess i picked up that "lingo" in my past life as a proposal writer for govt funding (read: BS generator). But thanks for the tip. I'll steer clear of that term in the future. :D

To be fair, neither does GNU Grep - just do `make' (without `make install') and you're good to go.
Obviously you have to compare the likelihood of remote code execution in nginx/apache to that of ssh. Nginx is much, much simpler than OpenSSH.

And, obviously, giving a third party remote root SSH access to your server already is a glaring vulnerability.

There are two kinds of people with pet causes I appreciate

The altruists, who dedicate years of research and learning to finding and giving freely medical or other breakthroughs to make a better world. I am glad they exist, please give them my tax dollars, but I stopped trying to fix the world around 35 years old.

The other kind is patio11 kind - sorta altruistic - but getting paid altruistic. Since my Damascean conversion at the age of 35, I appreciate this kind too - you cannot have my tax dollars but you can persuade me to buy

The world needs both kinds. Well, it needs the first kind, it will never be short of the self-interest altruism. And since his pet cause is about making me money, I like his self interest.
I suppose it is a fair thing to say that when listing the sins of marketing, reporting accurate increases in metrics that one cannot be sure they are responsible for would appear rather low on the page.
The payment UI looks unfamiliar and slightly confusing.

* Why are the labels _inside_ the input field? It's surprising when you can edit _some_ text in a well but not all of it.

* Why is my email address under billing?

* Why is the CVC field on a different row?

* Email, name, and street address fields will contain long data. Neither my street address or email address will probably fit in there.

* Why is the year only two digits? Y2K led me to believe two-digit years means accidental ICBM lanches.

Also, I spent fifteen seconds wondering why I couldn't flip the switches underneath "Effortless for everyone" on https://gethelium.com/. I even tried dragging the switch nub left and right.

I hope this helps. This looks like a really useful service. I'd love to look at the integration documentation (if there is any).

Interesting implementation! I'm using CodeMirror tokens and regexs to make numbers scrubbable and hex colors pickable: http://tributary.io/tributary/2958568/

I've been wanting to explore the route you took more, especially for doing even more code modification. I'd like to let users click on a number and turn it into a variable, or have a special object where members are added to the global table. You can then create controls external to the code with that table and hide the code (good for presenting after you're done coding). Looking forward to checking out your code!

> This core piece of technology solves one of the constraints that limit jet engines to a top speed of about 2.5 times the speed of sound, which Reaction Engines believes it could double

Is that 2.5 times the speed of sound limit just for jets at low altitude? At high altitude it is certainly not true. Both the SR-71 and MiG 25 did well over Mach 3.
I'm not sure why you're focusing on Charles Elachi or his job title (properly, "Director of JPL") here.

Charles Elachi (http://www.nasa.gov/about/highlights/elachi_biography.html) is an eminent scientist in his own right (follow the link to see) and you can bet he's very well-informed about MSL, which is JPL's biggest mission right now. This is because Charles has been running JPL ever since MSL was in the planning stage. His job would include briefing all interested parties about the progress of the mission and its instruments for about 8 years now.

In no sense is Charles Elachi "just like every other armchair scientist".

Besides this side show (I work at JPL so it's bothersome to read mischaracterizations of Charles), I agree with you that this story has been shifted beyond what it actually means. If I read you right, that's what caused you to comment. "Organic" has been changed from its chemistry meaning ("containing carbon") to its lay meaning ("coming from something living"). And "perhaps" has been left out completely.

Charles is a careful speaker and a veteran at communicating results to the public. This is why his statement contains a specific disclaimer ("not biological"). You have to give the article credit for getting this right.
It's a valid zip, but not for the state of Arkansas. It says he entered "Arkansas, 12345", which is something that could be automatically caught.

, so there shouldn't be any eye strain.
and made the product worse (a heavier screen farther away from your head).

I think you're being both unreasonable and ignorant--who're you to say that adding 30 entire grams (while exceeding the original specs, most importantly refresh rate) is making the product worse? Additionally, how do you know that a change in screen distance is better/worse?

Don't be a jerk. :(

Ugh, I hope this isn't an indication of any trouble they could be having raising.
The explore function could be moved a bit more front and center, they have incredible data to go head to head with yelp.
My point was mostly that they sell other stuff but you have to go looking for it. The business class desktops are mostly for IT standards, so they don't have to update the image so frequently.

Making major purchases once a year and always getting the new stuff, you get 4 processors over the life of the hardware warranty (4 years, which I also believe is the timeframe for capital depreciation).

Purchasing 2x a year, you'll end up with 8 CPUs in the environment unless you opt for the 2H purchase to be the same as the 1H purchase.

If you're buying new hardware every quarter, those agreements become more important if you want to keep your environment homogenous.

If you're running thousands of servers, is it better to pay a premium on your hardware to be able to get the same machines for the entire year, or do you want to incremental improvements and environment fragmentation resulting from updating? Different models sometimes have different utilities to manage them, and now you're writing abstraction layers to handle mass updates.

I agree that predictability of performance requires dedicated hardware. I'm just going from the IT perspective.

Not helping my cause here, but I am a 10+ year industry "veteran" with those problems :O

But sometimes it is easier said than done -- at least that's how things seem to load on my plate. Do you remember the old chestnut on rocks, stones, pebbles and sand [Well, here it is: http://justinlim.wordpress.com/2006/11/28/of-rocks-pebbles-a...]. Somehow it seems like I am always given sand, filled to the brim in my bottle, right from the start! :-/

Hey Troy,

What's up with ABsoluteMaybe? Are you still using it. I implemented my own EF storage interface, but after six months the queries started bogging down and I had to kill it. I've been meaning to get it back running.

Your out of the box storage is just a serialized file, right? The whole data set is stored in memory? How does that scale?
This is great news, but it also makes me a bit sad - because all this innovation died down in the 80's when everyone lost interest in the space race. We could be 30 years further down the road already and many of us probably won't live to see people setting foot on Mars.
The wrong lesson from this would be to immediately try and get your sites' performance to similar numbers. But what isn't explicitly stated in this post is that at the root of it, these guys first figured out which metrics matter for their goals. Only then did the optimization pay back. In their case, a few seconds can make decent impact because of volume. Someone with 100 uniques/day may have a better metric than load time to optimize.
Actually, this makes me wonder why every institution doesn't have an unregulated broadcast channel like this. Seems like it's a great way to embrace community. And I bet you that, if you run it long enough, there'd be some tangible value come from it, as well as the intangible value of fun.

In physical environments, we all have 'water cooler' conversations all the time. As we move more into 100% virtuality, is there a need for a digital analogue (if you'll excuse the somewhat jarring juxtaposition of phrases there)?

You don't need to put 12 million pixels on your head. 12 million pixels is useful on the desktop because it's nice to have a high density display anywhere you look.

For an HMD you only need "retina" resolution straight ahead. Peripheral vision can make do with a much lower resolution. I have no idea what the magic number is for retina HMD, but it'll probably be smaller than 12 million pixels. It's certainly possible that the 5" 1080p display used in the latest HTC could have a higher apparent resolution than putting 3 WQHD monitors on your desk.

And also keep in mind that higher densities are much easier to manufacture affordably in smaller screen sizes. There's a reason why you can buy a phone with a 440PPI, laptop displays with 220PPI but it's hard to buy a desktop monitor with more than 110PPI.

Why is there a Gator function when the only interface is `Gator(x).on(e, s, c)` and `Gator(x).off(e, s, c)`? Why not `Gator.on(x, e, s, c)` and rely on the caller to do partial function application (e.g. with `Function.prototype.bind`)? This seems like unnecessary memory bloat[1].

Well, in those cases I usually just read the text of the review and see whether it's from someone who would give 5-stars to any Applebees, or whether the person is slightly more aware of what decent food should taste like.

The users seem somewhat more literate.

Is The Worst better than The Best?
The US legal distinction is "substantial non-infringing use". If you are up to something and, like a search engine, happen to facilitate IP infringement, you're good. If there is no significant purpose to your service other than to help crime, it's criminal.

There are plenty of similar crimes: Conspiracy, harboring a known fugitive, material support for terrorism, receiving stolen goods, RICO. These can be misapplied, but the basic principle is reasonable: helping people commit crime can itself be criminal.

I don't think that's the problem here. I think the problem is with an IP system that's built on assumptions 100 years out of date.
Reminds me of the time I was volunteering in an office, I must have been 15? And there was a solar eclipse, so I used "net send" to broadcast "Come and watch the eclipse on the roof" to every computer in the building. It was pretty cool; a few dozen people showed up.
I've been a loyal Thinkpad user for how long and I never knew this? Thanks for the heads up.
And some of it doesn't even require unsafe code. In many cases C#'s compiler optimizes away the array bounds checks.

I think there's also a very plausible argument to be made that in C# garbage collection is often a performance bonus, not a performance hit. It's a rather different beast from what a lot of other GC languages use. For some specific kinds of applications it's definitely pure overhead - but for the business applications the language was designed for, the speedups you get from improved locality of reference and overall faster allocation and deallocation of small objects can more than outweigh the cost of the collection runs themselves.

Lower-level languages are great for when there's a lot to be gained by carefully managing CPU cycles. But considering how expensive (relatively speaking) a cache miss can be on modern hardware, there's a real danger of falling into the trap of being penny wise and pound foolish if you're not careful to take some time to diagnose your performance situation before writing prescriptions for it.

Hard drive and network cost per gigabyte is always falling, and much faster than the blockchain is increasing, so it's not expected this will be a huge problem. But what you say is true that it will "centralise" more in a sense - but the barriers to entry will still be much smaller than any other financial institution so there will likely be many groups still involved with processing the block chain.

If it's just the download time that's bothering you, try the electrum client: http://electrum.ecdsa.org/

It uses a remote blockchain so that you don't have to sync with the network. But you control the wallet (the private keys that let you spend the coins) so it doesn't suffer from the problems of the online hosted wallets where you are not in control of your coins.

I'm trying to get a sense as to how exactly the head tracking will correlate with the controls. From the videos I've seen, it looks like the implementations so far have your head movements working in some combination with movements coming from your mouse/game controller.

Maybe it's just me, but I'd much prefer controlling my character's body (i.e. where the gun points) with the traditional controller/mouse, and use head tracking to move my character's head/camera only.

I think it'd be less tiring that way, and probably more immersive too. As I'm moving around in the game world, I could easily look around without changing the direction I'm travelling.

First, without knowing the makeup of files he has, you can't tell how much a corner case this is. It could be 100K small files or 10 large ones. Few care about runtimes for small files, but many care about runtimes for large ones.

Also, and probably more importantly, you'd use ack differently in a recursive-find situation. You just "ack" from the top of the tree. The perl interpreter starts only once.
