> More accurately, when the feature is standardized most browsers recognize both the the prefixed and unprefixed versions. This is still a significant competitive advantage for Webkit since there will be a lot of legacy content out there that uses only the -webkit prefixed name. This situation is an incentive for Webkit contributors Apple and Google to delay disclosure and standardization of these features as long as possible, and the W3C discussion above indicates they are doing just that.

I think you're misattributing malice here. This isn't a WebKit only issue, this is a first-to-market issue. When some new css or js feature is proposed and vendors implement it with the prefix, some developers rush to hack on it, submit their demos to HN, and then forget about it weeks later. They don't bother to go back and update the css later with other prefixes.

The same issue exists when WebKit isn't the first to market. WebKit doesn't support calc() yet. Mozilla does. Plenty of abandoned webpages will never be updated with other prefixes. But are these serious websites/businesses? Is Facebook or Twitter sticking in -webkit and never bothering to go back?

>Once something is available to the public, developers will use it and often with good reason. That's where prefixes are most destructive. If Chrome comes out with a -webkit-sparkle property tomorrow, advocates of prefixes would have you add -moz-sparkle, -o-sparkle, -ms-sparkle, and plain old sparkle immediately just in case it becomes a standard. Nuts! It would be better for non-Webkit browsers if we just started with plain old sparkle so that legacy content would not be forever broken to them.

Legacy content would still be broken because sparkle will likely be changed in the process of standardization. IndexedDB has seen some dramatic changes in the course of its development; all those sites that implemented an earlier version will be broken when the standard is finalized. The vendor prefix sends a warning to the developers.

Browser sniffing is a far bigger problem than vendor prefixes. Google is one of the worst offenders, especially in mobile where they send UAs not equal to iOS or Android to some poorer version.

Your pothead brother makes his living off the site - i.e. it is a lifestyle business and that lifestyle is...well, pothead.

I don't get the impression that his being a pothead was something you were unaware of going into it.

Yes, I do that for certain files in my Dropbox. But opening one of these files requires opening truecrypt, mounting the file and then opening the files inside the mounted drive. I wish that I could have this security, but be able to open an encrypted file in one-click. This could be possible if I were able set my own private key, and then the Dropbox (or Google Drive) client would encrypt all of my data as they transfer it to their servers.
Ask HN : Is your LAMP server secure? How?
I recently had discussion with my colleague about securing own's web server. According to him, a server is secure when you "show" what you want to show to public and what you do not want to be public is always inaccessible to them.

My questions:

Is it a acceptable definition of a secure server ?

How does file permissions affect server security ?

What are best measures to consider to secure own's server ?

Thx jgeerts - essentially junk mail can be put into to two broad categories: ones for which your name appears on a "list" somewhere & ones that are carpet bombed across zip codes/routes.

The former has a pretty decent chance -- pretty high with reputable companies, esp mags/catalogs/credit cards/etc. The latter, it's case by case. Some honor it (eg Valpak), some have no way of suppressing you.

In either case we provide you Sender info (click on the company tab) w information in case you want to give them a piece of your mind :).
Single-year performance is a terrible measure of the value of an investment.
I would totally buy this theory.

I think that tradeoff with the zero-shutter-lag feature is that the phone does a cursory attempt at focus/metering/white-balance (if it does one at all) and totally misses it most of the time.

You can try to focus by tapping the screen first, but it still doesn't quite get it right in my experience.
Leave room between the lines so you can add stuff. Mark it up as you evolve it. If you need to, you can rewrite the clean version on another part of the board. Better yet is if you can figure it out in your head before you start writing, becaus that will definitely make you a better coder.

I was speaking about people like Dr Stroup or Dr Petrosino (I've had a class with the latter and read papers by the former) who are experts and have written compelling papers. However, you're right, my wording was bad. Anyone with a proven track record or some accomplishment in teaching should be considered. Both of these people have PhDs, I'm pretty sure, not EdDs.
I like playing with JS. It's nice to have JS on both ends.

lessc is part of less.js (https://github.com/cloudhead/less.js/blob/master/bin/lessc), so should be identical, but fair point.
The forum and cms options in rails are fairly abysmal right now. I've worked with refinerycms a bit, and it seems to have the most potential so far. No rails forum packages can compete with phpbb, though.
Unfortunately, the entrepreneurial success story tends to get corrupted by the noisy example set by tech blogs, and pundits glorifying the investment cycle represented by companies like Groupon, Yelp, etc, rather than the quiet success stories of much more common but less high profile businesses that simply create things that people want and are willing to pay for.

What results is confusion in the minds of young entrepreneurs between what it means to build a business and what it means to swing for the fences. Big ideas start can start small, and that does not preclude the possibility of swinging for the fences, but building the business should be the motivation and the priority, not visa versa. In fact, starting small, cultivating a product, and staying relentlessly focused on customer happiness is the right way to sart a business regardless of how big your ultimate ambitions are.
In the past it's been mainly useful if you can flee from a region in turmoil to one with more stable conditions. For example, my grandfather fled Turkey for Greece in the late 1910s (http://en.wikipedia.org/wiki/Greek_genocide), taking some gold with him that he was then able to sell in Greece, using the money to help resettle.
Good links, thanks all. I ended up buying the 'Getting Started with Arduino' book (https://www.amazon.com/gp/css/order-history?opt=ab&searc...) and there's also a parts package for the exercises you can buy to keep things simple - http://www.amazon.com/gp/product/B004HL44MI/ref=wms_ohs_prod...
I'll just add that even though the job ad isn't up yet, we're specifically looking for you quantitative big data folk.

Apply through the ordinary software developer position for now -- but we're hunting for some passionate data engineers to do more stuff like this: http://david-hu.com/2011/11/02/how-khan-academy-is-using-mac...
Similar to how graduating college shows you were able to work hard and learn many different subjects effectively for four years, being able to solve a google problem shows that you A) are smart enough to have understood and retained it from when you were first taught it or B) were driven enough to sit down and learn tough conceptual problems in a few weeks.

So, its less that you know that particular subject, and more what you being able to pick it up is an indicator of.
I'm more interested in the "distributed" part of the story. Version control can be fitted into any database with a bit of hacking, but a distributed ACID database where you can commit to any node and merge with any other node sounds like a really interesting concept.

Especially when combined with the fact that it is extremely difficult to forge git history without getting noticed, people could use something like git as a reliable, scalable, and censorship-resistant platform for data sharing and storage.

I had a Wordpress blog for about two years on one of those $4/mo hosts referenced in the post, and I was getting the same slow, lousy performance.

I hosted it myself for a while and also decided I hated the headache. I knew I was going to do some hosted solution for my next blog, so I looked around and ultimately went with Tumblr - a more social ecosystem I expect will eventually surpass what Wordpress has going for it.

Here's the post I wrote describing it:

Ah, but not all shareholders are in it for long-term gain, so they don't necessarily want a CEO that aims for the long-term. And even those that are technically in it for the long-term are hand their money off to Fund Managers, who as recent times have shown aren't that great at long-term investment either.
I use it for quick social arguments and commentary a lot.

Do you honestly believe that Warren is trying to deceive you into investing in productive assets rather than a shiny metal because he wants to manipulate the market?
I've been volunteering once a week at a local school teaching 6th graders how to code, and it's really amazing how quickly many of them pick it up. Even small things like learning to mix blue and red to make purple using rgb(255,0,255) is utterly fascinating to them.

I asked one of the kids how he would like it if they taught programming as a subject in school. His eyes just lit up and said "that would be awesome".

It's also fun talking to kids about startups - the fact that you can use code to solve problems for people and start a business. They're usually more interested in building a fun game but still, you can see some flickers of awareness lighting up. A lot of these kids are selling candy to each other at school anyway, so they're pretty entrepreneurial by nature.

I guess this is a long winded way of saying that teaching kids to code is one of the most rewarding and challenging things you can do, and I'd highly recommend it to anyone on the fence.
You reveal a huge bias by the fact that you selectively pick only an extreme event that spans about 0.001% of 30 years as a prime example.

The wild peak of gold in 1980 lasted for days, on a temporary burst higher. The average price of gold in 1980 was $615 or so. Your scenario requires that buyers of gold do not cost average over time, but rather that they only buy at very specific points in time and only sell at very specific points in time.

You could have just as easily purchased gold at $55 in 1972. Or $125 in 1977. Or in 1985 at $300. Or at $266 in 2001.

You make my point about gold: it's a wealth protector, not a vehicle for seeking big real returns. If you had bought gold in 1850 and passed it down the generations, that wealth would have been completely protected from the fiat disaster of the green back the past 90 years. You would not have grown the wealth in some spectacular fashion, because that is not what gold does.

I had the opportunity to interview with Google. Overall it was a great learning experience, and demonstrated to me the skills and aptitudes required if I wanted to play with the "big boys".

Regarding their interview questions, you either know it or you don't. From my personal experience, Google's rounds of questioning are intentionally designed to weed out the people who fake it or try to cram up beforehand. For software engineering, they are interested in applicants who naturally demonstrate keen skill when it comes to CS fundamentals (algorithms, data structures, discrete mathematics, etc.).

Throughout my phone interviews, Marissa Mayer's quote "A good student excels in all subjects" kept running through my head. After interviewing with them, I believe Google holds all their employees to a similar standard.
So this is really more of an image thing -- site responsiveness, accessibility, and so forth. Similar to how a shopkeeper might have paid 2500 each year to have a sign custom-painted out front.

In that case, makes sense. I'm not an extreme cheapo -- I'm probably paying 1800 a year for my various hosting solutions, but that's spread across HostGator, a MT hosting company, and AWS. I'm moving to AWS -- exactly in the opposite direction that you are heading -- because I like buying cycles. I can set up databases, write code, and have more power to write hybrid sites. I'm beginning to look at producing content on the web, blogs, apps, static sites, or mixed-mode stuff, as more of an art form and less of a pre-canned WP experience. So I need a box, not a service.

But I look at this as simple content. I'm serving bits to folks who come and consume them. I don't generate consulting leads though my sites, I provide data people want for free, so as long as most of the people get most of the data, everything is copasetic on my end. It sounds like we have completely different purposes.

Just as a off-the-wall suggestion to other readers, you know you could write a script to consume your blog entries and move them to a CDN as static pages. You'd get a hell of a boost in performance, and I don't think you'd really have to change much. (Probably much tougher than I make it out to be. Haven't really thought it through. I use URL rewriting on some of my newer sites, so it all looks like static content anyway.)
Do you have any tips or resources for teaching children? I have a 12 year old in the family who I would like to get started. I can teach him html/css but anything beyond that we would be learning together.
Yes, and then immediately after taking the gold he changed the standard, so if you wanted to buy your original gold back you would have to pay more money. What happened was robbery.
The free version of WebWorkbench does this for coffeescipt in Visual Studio. I think the pro version does it for less($29). I'm thinking of paying for it depending on if I can get this simpleLess working on Windows or not.

Electric cars will go mainstream when:

1. They become priced like regular cars
2. They have the range of regular cars
3. They come in form factors similar to regular cars
4. They are cheaper to own and operate than regular cars
5. They stop being about "the environment". San Francisco is not the entire US.

It looks like we're getting a bit closer to all of these milestones, which is good.
I'll upvote this if only because I'm not that young, I have obligations, and I would prefer to have extracurricular activities. I am easily discouraged by the constant stream of wunderkind success stories, and the relative dearth of more "normal" people succeeding. By now I think I've realized that this is because of what sells in terms of news.
Comparing the price-change in gold to the price-change in just one stock is cherry-picking the data, no matter how correct your main argument is.
Except they paid market rate knowing full well what would happen to the buying power of dollars relative to gold. I like how people are willing to redefine theft to support their notions of benevolent government. You guys are a riot.
I'm sure many people DON'T understand that, as it's fairly normal to see peoplecriticizing "free" companies (Facebook, Flickr, etc) for excluding them when they clearly violate their TOS (sometimes more than once)...
"If you want to create the future, the possibility of successfully navigating a patent minefield is approximately 3,720 to 1."
Ya sometimes my posts get a little long and I draw conclusions that may not mesh with my original hypothesis. I should have probably written something more like: let's create our own environment and treat existing APIs with the same skepticism we would have for any other library.

Right now the biggest cost to my time happens whenever I have to interface with other people's code. I race ahead very quickly on my own, but find numerous bugs either in the implementation or even the overall approach that libraries take. Show my any library, anywhere, and I'll give you anywhere from a couple to a few dozen flaws in a short time. I've actually pondered making a database of library flaws hahah.

Correction: thinking about it as a way to attract product.
TL;DR: the key part is in this bit:

“Consistent with the Constitution of the United States and notwithstanding and other provision of law,” it says (emphasis added), entities may act to preserve the security of their systems. This means that the only law controlling their actions would be the Constitution.

It’s nice that the Constitution would apply</sarcasm>, but the obligations in the Privacy Act of 1974 would not. The Electronic Communications Privacy Act would be void. Even the requirements of the E-Government Act of 2002, such as privacy impact assessments, would be swept aside.
Indeed it's really sad that here in the U.S. our school system's do not offer coding classes as electives.

They don't? I took Logo and BASIC programming on the Apple IIe in 7th and 8th grade (1988, 1989). BASIC on the PC in 9th. Switched to Pascal and covered all the basic data structures and algorithms in 10th - 12th grade. That was a looong time ago. Surely computer education in schools has only improved since then in most places, right?

.... only to devalue the dollar by 50% or so as soon as it was believed there was not a lot of gold left in private hands.

While "stealing the gold" is not technically correct, eliminating 50% of the value of everyone's saving IS, and the confiscation of gold was done to eliminate the best (and popular) store of value.

Of course, it was all legal -- but when the government makes the laws, that statement is completely moot.
In reality, the Dow is not at 13,000 today as we knew 13k to be back in 1998/99 during the huge stock market bubble. Inflation has eroded that nominal value by at least half. The Dow is more likely at 5,000 to 6,500 depending on what you believe real inflation has been over the past 14 years (not the Fed's bogus CPI numbers).

Am I correct in interpreting this to mean that you believe that inflation has been 100% over the past 12 years (that what you could have gotten for $13 in 1999 would only get you half the same basket of goods today)?

I ususally use lynda.com resources. I also have problems with teaching something beyond html/css, but usually with enough repetitions and assignments students finally "get it". Brightest students of mine are the ones who really interested in programming. So, in order to make it interesting, I tell them about what sites like Google and Facebook are programmed like, how their best video games work, how they can make a "simple" version of their facebook like social site. They seem to get motivated by those talks of mine :)

It's a lot like making your own circuit boards vs ordering silkscreened boards.

You can pay a couple of bucks and hours to get a single working board. Or, you can pay pennies per board, but you have to get lots of them.

The beauty of a die is you can put it in a big press and stamp out a million of whatever. it's fast too. Seconds per item. With a 3d printer you have to wait, possibly a day, for a single print to complete.

I think, in the short term, your die maker should worry about your dad getting a fancy pants cnc machine to make his own dies.
I always find it interesting that Babe Ruth was, at the same time, the home run leader and the strike out leader. If you swing for the fences, chances are, you will fail more than you win. Hitting singles, consistently, is actually far more beneficial for both you and the team that you work with.

I am going to make a wild prediction right now. Taking into account that 2012 seems to be the year of the "legit" free online schools. I am going to predict that within 5 years a person will be able to get a high-school or college degree (possibly accredited) from Khan Academy...and it will be recognized as legit by peers and employers alike.
The Dow doesn't get to drop GM after it goes bankrupt and then not count its losses. The decline of GM hurt the Dow index just as much as it would have hurt anyone else that bought and sold GM stock when the Dow index added/dropped it.

It also represents an average of the market, so the fact that it was hard to mirror it exactly is not particularly relevant. Mirroring it approximately, or buying any other large basket of stocks, would have led to roughly the same result.

While it's true that an investment in Gold was better than an investment in USD, it wasn't better than common stock equities. You said the only way to capture a return better than Gold was to buy a particular stock at IPO, but that's just factually incorrect.
