Would you clear this up for me? That's what I got from the official website "To Qualify for the H1B Visa Program, you must work in a specialty occupation: IT, Computing..." Good. I have a Bachelors degree, but in an unrelated field. Would that be a problem for authorities as long as it's not the problem for the company?

FWIW, Duby is not "done" or "ready" yet, but it's moving along. The promise of a static-typed language with all the expressive power of Ruby (or at least, Ruby's syntax), but the performance of Java and no runtime library is very compelling to me.

This doesn't make sense to me. Any "legacy" systems involved surely pre-date online account access by consumers. They would not have ANY password field or even any notion of a "user" in the sense of someone who is able to access a specific account.

This would have all been built as a web application talking to the backend through a CICS gateway of some sort. The web app would be responsible for authenticating the user, not the legacy mainframe system.

Any book on Walmart will talk about their IT systems. Their main operations room looks like NASA's mission control. I recall that Walmart can redirect trucks on the road via satellite to different stores whenever demand suddenly fluctuates.
The increasing storage problem applies to hard drives, too, and the increasing need for something like RAID6 over RAID5.
Come on! It's a website, and I'm sure it's not using Cobol Server Pages (CSP), so why now just put some simple logic between the web controllers and the COBOL logic?
Moissanite is the way to go. I got married last fall and didn't even give her the option of a diamond on principle. Nobody asks if it's real, they just think you're loaded because you're fiance is wearing a $800 rock that they think cost 20g. My friend who just got engaged had a completely custom setting designed + moissanite -- more thoughtful and less expensive than crap from your local jeweler and nobody can tell the difference. The hardest thing is getting over the massive psychological pressure that people will think you're cheap. Know what I told myself? Man the fuck up and stop being society's little bitch. Besides, two days after the wedding neither of you will ever think about it again.

edit: un-diamonds are also a great litmus test. if your girlfriend learns the real story of diamonds and still insists on having one you're probably in for much bigger problems than just the ring.

Not if he can show that he owned the domain name before Apple established trademark. Now here is the tricky part if you use it to blur Apples Trademark on tablet computing and possibly (it's a stretch) Personal Electronics it could be argued that you are trying to cause confusion in the market place. If you offer to sell it to apple you could be accused of squatting if you owned it before Apple established trademark then you have a defensible position.

So,

Selling iPads would give the indication that you are an Authorized reseller, you are not which means legal trouble.

Selling software or ebooks for the iPad is a gray area, while it is not a competing product for the trademark it could successfully be argued that it is causing confusion in the marketplace.

Selling a USB enabled trampoline that you have named the iPad will most likely still get Apple after you, but it is very defensible, unless Apple could successfully argue for broader coverage that the Trademark applies to all personal electronics.

Ask HN: Can you help me find this site? (Similar to Python Challenge)
I was speaking with our HR manager with regards to a site we both remember from the high school days (circa 2003). We were considering implementing it as some sort of hiring challenge.

It's a really geeky puzzle site where in order to proceed to the next level you need to change the URI to get to the next link. The URI would be the answer to a puzzle, or some sort of clue-figuring based on the source code of the page, a riddle, etc.

Does anyone remember such a site from back in the day? (Assuming it's still up, that is!)

Thanks.

They do include the entertainment system of the car, which has to have some GUI controls, probably some map rendering and speech recognition, which unsurprisingly adds up to a few more lines of code than you would expect from steering alone.

Of course, the entertainment systems of planes mostly run some kind of Linux or Windows CE, which include a lot more code than the above. AND they deploy one entertainment system for every few seats, so you would have to multiply the lines of code with that. AND all those displays have some microprocessors (or FPGAs) of their own, which add to the number of "ECUs".

In short, the article is just not fair.
Interestingly enough, just last week I saw a talk given by Jack Szostak (http://en.wikipedia.org/wiki/Jack_W._Szostak) who researches, and has actually constructed, proto-life forms. Before a cell needs to worry about an energy source, it needs to worry about sequestering genetic material within a membrane, growing and dividing. Dr. Szostak has demonstrated very simple solutions to these problems for early life. An assumption of his work is that activated nucleotides (the energy source) are available in the environment and can freely cross the membrane.

Dr. Lane does not seem to be arguing that there wasn't a "primordial soup" but that it was concentrated in and around these vents. One problem with this idea is that early cells likely needed temperature fluctuations to replicate their genetic material (like a primordial pcr, except with spontaneous nucleotide assembly on the template instead of having a polymerase), since they would have lacked the machinery to do so.

You are absolutely right. I thought about that last night after I wrote this post. In retrospect, I hadn't considered it because (1) the overall level of education required by the ABA is so much less than that required by for a physician (3 years of grad school vs. four years of med school + an internship/residency) and (2) it's much easier to go to law school part-time or in mid-career. Part-time medical schools are few and far between.

First time I heard Quirksmode curse like a sailor. Regardless, the reason I can't develop for a Nokia, Blackberry, or HTC is because I don't have a Nokia, Blackberry, or HTC. I have an iPhone. It's pretty easy to develop webapps for it because if it looks good in desktop Safari, it will probably look good in iPhone Safari. I don't even know the browsers that other phones have. I know Opera Mini is on many phones and Firefox too. I try to make my sites work well with desktop versions of these browsers. But there's no way I can guarantee that my sites will work well on all the browsers everywhere.

Already I have to worry about:
* Firefox 3+ (all OSes)
* Safari (OSX, Windows)
* Opera 9+
* Chrome 3+
* IE7+
* iPhone

There are just so many browsers I have to worry about. And even though I code for standards, every browser still treats every little thing slightly differently. I realize making something work in Opera if it already works in FF/Chrome is probably not too difficult, but sometimes little things can take up hours. So sorry Quirksmode, despite your well-written article, I will not even bother with any other browsers just because you say so.

You know when I will bother? When my users tell me that my app doesn't work well in platform X, browser Y and they would really want it to. That's when I will go beyond my basic list of browsers. Otherwise I'm just wasting resources developing for yet another platform.

Or because it's not as much of a tremendous waste of time. If you're smart and motivated, you can probably complete the average high-school class in an afternoon. The whole thing is an exercise in grinding speed-limited to the slowest kids in the class. If I could go back, I would have dropped out, gotten a GED, and went to college when I was around 16.

Perhaps a good thing for "mission critical" software to do might be to implement software "hash checks" where the software keeps a running series of hashes of what it thinks it has written to disk, and then compares that against the actual stored bytes at the end of the operation. Or, if that is impractical, have a "safe mode" intended for kernel builds, software releases, etc, where it will compile and build twice, then compare the two for differences. That would solve a lot of the problems the author is postulating, however unlikely they might be.
Frankly, I find this terrifying. So, I'm hurtling down the highway in a sheet metal box travelling faster than the fastest land animal, controlled by hundreds of millions of lines of code, and bugs in this code could erroneously stall my car or trigger my airbags? That's too much. It's too much code. More code means more bugs, and now more bugs means more danger. I'll gladly trade in my GPS for a car that could still drive even after being hit with an EMP. (Not that I run into electromagnetic pulses regularly... I just trust the mechanical stuff more than I do the code.)

Ask HN: Please Review My Startup: BeBefore

The irony of this article is the only way for him to get the control he wants is to be on Facebook and monitor what is put up about him. Only then will he be able to see what he doesn't approve of and ask those people to not put them up.
If I were 16 now I'd spend the extra time on Open Courseware and go to college only when I had done enough exploring on my own to really take advantage of the profs' expertise.
It's not about the iPhone, it's about Webkit.

He seems to forget the fact that hardware sales doesn't translate into actual internet usage. The internet outside of iPhone, Android, and Palm is so terrible that barely anyone even bothers to use it. What do those three platforms have in common? Webkit!
Glad to help, a couple more before I go back to obsessing over my own pixels...

The vertical spacing between the green headings could do with tweaking, more space above and less below to tie them to the block of text they go with. Top headline text "Keeping tabs..." has the dots of the i's and the left edge of the 'g' sliced off. Your logo is nice but the wordmark looks (to me) very corporate and squashed up; maybe incorporate some blues from the logo and use looser kerning.
check the sparkarea example, it has a lot more. You control the datapoints and the width, so it's all up to the person implementing it.

Millions of lines is an exaggeration... You can't add up the code for the ABS to the code for engine control, to the car navigation system.

Those systems may share information, through limited signals or simple data busses, but they are separate, not a big code blob like a PC or a server.
Seed capital for social entrepreneurs
I wanted to pass along a new opportunity for social entrepreneurs that started just this month - the Pepsi/GOOD Magazine Grant (http://www.refresheverything.com/)

Instead of spending $20M on Super Bowl advertisements this year, Pepsi decided to put that money towards new, social projects looking for funding. There are four categories - $5K, $25K, $50K, and $250K - and Pepsi will be taking submissions every month throughout the year! I'm currently in the running for a grant and thought that I should pass the funding idea along to other social entrepreneurs. It's obviously not all about the money, but seed capital certainly helps!

If you're interested in taking a look at one of the grant submissions, feel free to check mine out (and maybe vote too!): http://bit.ly/aGPq9u

A shameless plug for my project:

I've been working on a music education project called Chromatik (www.chromatikmusic.com). It's a collaborative online home for music education, for students of all genres and experience levels, that provides study tools while also capturing the arts advocacy conversation. Music education has been a huge passion of mine, and I'm seeking to really shake up how students get their study tools, collaborate, and approach learning.

Chromatik's floated around from 6th to 29th place already out of 300+ proposals in our category, and it's been a totally viral effort...which speaks to the interest in music education and (hopefully) the coolness of the project at hand. I'd be happy to chat about Chromatik or the competition, if you're interested.

The problem is that the real money in affiliate marketing is in the shady stuff, and the shady ads (with the most payout) take over the "good" and "decent" ads.

Sure there are legitimate affiliate marketers making decent money (like someone established with a good forum on webhosting), but another problem is that for an upstart to do that they have to apply less honest methods.

Ummm... I think you can make that argument for ANY chart type. I can't differentiate between 25% and 24% in a bar graph either.

In fact, IMO, bar charts (normally) have the far worse problem of being relative to the largest value. In a percentage situation, you want the size of the bars to be relative to the whole, otherwise its misleading to say the least...

So the take away fact is that all visualisations have weaknesses under certain conditions.

But to offer graphing library that does not offer pie charts is, well, a bit silly in my opinion.

Since almost every dynamic language is at one time or the other compared to lisp or praised as lisp + syntax + better + ..., I don't think the view of the Factor community is important.
I don't think NPR as a whole does - are you suggesting a company wide conspiracy against Toyota within NPR?

Going by the two quotes you highlight that doesn't indicate they have it in for them. If anything they highlight how rare the problem is (to me at least).

Coverage else where hasn't been much different either IMHO.
This sentence caught me: when we all know senior year is a waste,.

Personally, in my senior year I racked up AP Credits for English and Calculus that applied to my college and participated in a Constitution Contest where I both learned a great deal and got a trip to DC that was at least subsidized by the school (so far the only time I've been to DC).

I may have been able to achieve more by going straight to real college courses, and I know not all schools offer the opportunities I took advantage of, but I would hardly say it is self evident that senior year is a waste.
I'd say little to none. This, of course, excluding the kind of stuff you can do just by interfacing the engine ECU with a computer (using the OBD-II port that all new cars have).
My initial reaction was "spam" (Im still not comfortable about the whole site!).

But the content is actually reasonably useful if your researching a product. If it's a serious site then it definitely needs a much better interface and description!

(edit: I say that last bit as someone who gets so annoyed when browsing Amazon/Ebuyer etc. and the product specs are incomplete or completely missing - this looks pretty complete for a lot of products. I'd be interested to know where the data came from?)
Depends on how cute she is...
I looked at the Clojure code and I find it's so ugly compared to Python, Java, or C#. I don't know why would anyone considered that a contender for writing code in the long run. I know the three languages mentioned above and I find Python is the most easy to read and code. Code readability is one of the most important criteria for me.
Interesting. In Minnesota, red light cameras were found to violate due process, so they are no longer in use. Even though the red light cameras are no longer in use, all of the cameras that were set up in Minneapolis are still installed, they just aren't doing anything.
Any chance you could list a price on the page somewhere? I looked and looked, but couldn't find price range estimates anywhere. Pretty hard to evaluate a laptop if you don't know how much it costs, in my opinion.
The layout is neat, but the purpose of the site is not obvious at first. Is it a review site? A shopping site? It's only after clicking around a bit that one can understand what the site does (present a selection of products in a cleanly organized manner, and provide links for purchase on Amazon.com). The name of the site is a bit misleading (bebefore? I thought it was something about how things were "before").
Functions are indeed a good tool but at one point, they accumulate more and more parameters or more complex structures as parameters. Eventually, while you still understand the purpose of a function, it is difficult to understand all that it abstracts away.

I am just saying this because I totally relate to the article,it is often very hard to contain or abstract complexity. or it requires nearly equally complex mechanisms or abstractions.

Some of the metrics about how many users are active and produce a certain % of the content are somewhat irrelevant and are not a sign of downfall. In nearly every social network I've studied with the Web Ecology Project (http://webecologyproject.org) we've roughly seen that the top 10% of users create 90% of the content. This is true for everything from HN to Facebook.

It was a super easy story in 2009 to praise Twitter. It got people reading the articles and sold copies/advertisements. The news like stuff that is new. Now its time for them to step up to the plate and continue on with having an awesome, useful and sustainable service and company.
So, it's an affiliate site with info scraped from various sources?
