I'm bringing up an equation that needs consideration. PotentialDamage=NxP1xP2xP3xMaximumDamage

Where
N=Population of World
P1=Percentage of people with knowledge and access to Dangerous Technologies
P2= Percentage of Personalities who are destructive
P3=Percentage of People who actually act
MaximumDamage=The Number of Casualties that can be caused by a single person

While P1,P2,P3 is relatively stable, and N is almost linear, MaximumDamage is exponential. You can imagine weapons accessible to normal evolved from sticks, to axes, to guns and explosives. At the present moment the main reason that nuclear weapons are not in exploded by terrorists is not because of technology but because of scarce resources. But for bio-warfare, technology cost will exponentially shrink and impact will exponentially grow.

This means if this goes on, PotentialDamage will one day be larger than our population, and extinction will occur. By estimating these parameters we can even predict a data.
We have most of our workload running on Rackspace Cloud Servers (UK) and the more improvements AWS make, the more overpriced and ridiculously underperforming the Rackspace offer becomes:

Underperforming: I don't get why the bigger Rackspace Cloud Servers don't get more CPU cores, just a bigger share of the original 4 cores on the host server. This might look fine but at the end I just want more processes (PHP threads) running at the same time.

Overpriced: The pricing is really high for Cloud Servers. I'm paying around £460 a month for a 16GB RAM Cloud Server (4 cores, 620GB (!) disk). For around €448 I have a Rackspace dedicated server with 48GB RAM, 2 x 6 (modern) cores and a 480GB RAID10 array.

I'm actually switching most of our workload to dedicated hardware, it's less cool but it's just cheaper and faster, in this case.

NB: We tried AWS but the MySQL IO performance, either in EC2+EBS or RDS, was not enough for us.
This is my first attempt prototyping a responsive site - http://dl.dropbox.com/u/424079/NewAJLI/ajli.html

Used Skeleton's 12-column CSS framework, which was a bit buggy. Has 4 breakpoints - 960 width, ipad portrait, iphone landscape and iphone portrait. The gray border up top represents where the menu will reside and scale. I'm not thrilled with how we handled the transition to mobile - the varying blocks of text in 'who we are' and the subsequent example need to be more differentiated.
No, please don't. Those are reserved for different things.
ASP.Net might be behind the growth, but I wouldn't discount native application development (particularly in the enterprise space). Not everyone writes web apps, after all. :)

Some people say "proud of X" when they mean "refuse to feel shame about X". It bugs me a little also.

20% also seems too much. Castlevania SOTN ran on a 33MHz CPU, that's 1% of today's desktop machine. This game is 10x-100x less complex than SOTN, so it should use 0.01% to 0.1% of CPU. Also interesting to apply the same metric to RAM usage (SOTN used 2MB).
But for a low-budget startup the licensing costs are what'll get you in the long run. Stick with something free to use like ruby, javascript, php, etc.

I take it mono isn't a reasonable replacement on non-Microsoft OSes?
You're trying to equate doing a vocabulary test with writing for a public audience (and then using that writing as a proxy for judging the individual's intelligence).

Vocab tests and writing skills are not the same.

As unfashionable as it may seem, ASP.NET's ill-fated AJAX Toolkit library (before MS realised that jQuery was the way forward) still has the best date picker control: http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/...

The key thing is the ability to click the month/year headings to zoom out.
It's also handy in case you want to switch instance types. When instances are stopped you can change their type if they are the same architecture. This means you can now switch an instance around to all instance types they offer.

I do most of my other stuff Perl/Python and any other stuff apart from Java on Emacs. Some times on Sublime Text 2.

I am now planning to shift to ST2.

Even on an editor like ST2 which is awesome anyway. You get to see what an editor is designed for. Its supposed to make 'Text' manipulation easy. So that is what it is, after everything.

So Emacs with all its power is still a Text editor, albeit a very powerful one.

Every time I work on Text editor I focus on reading manuals and understanding stuff no matter which editor that is. But with Java,IntelliJ and Eclipse its different, I just throw in whatever little is there on my mind and just wait for the autocomplete to do the magic.

Some of my colleagues go a step far. They just can't write any Java code without an IDE and I see that's the case with nearly every Java programmer I've met so far! Even in interviews. Its sort of like if you are talking of Java development its taken for granted that its is happening on an IDE. You never know, a few days from now the Java language specification my include a IDE specification.

According to me tools and languages must enable you think more than you write. Unfortunately in case of Java(and now growingly Python) you just can't work without an IDE.
Just a way to make you feel good about not having a say.

I'm the maker of this game, very glad you guys had a fun time with it.

Regarding the Chrome warning, it is intended to be only a suggestion that the game plays better on Chrome. If it not supposed to block you from playing on firefox or other browsers!

I will make sure to reword that warning when the competition is over!

Also, I was pressed for time when making the mute button. It will have better functionality after I can update the game upon the end of the contest.

Thank you all for your suggestions, this really helps.

Just like how many programmers manage to program Java on Emacs today...

I mean does anybody have to bear that kind of a pain for no reason? And what you are going to accomplish doing that by the way?

I don't understand this self punishment and I don't see why this is even needed.
In Java, I've never seen a linked list implementation outperform the stock implementation of an array-backed deque for stacks or queues.

http://docs.oracle.com/javase/6/docs/api/java/util/ArrayDequ...

I highly recommend that every Java developer read the source for this class (and the rest of the java.util Collections).
Your stance is at odds with the article though. He's arguing that in order for mankind to move forward at a faster rate with the web some UI standards need to start coming about, like the Mac pioneered (inspired by Parc).

Having a custom design for every site means a user having to learn a new UI every time. It's mentally exhausting.

And as an added bonus the programmer doesn't have to rewrite code that been written a million times before by other programmers.

I was under the assumption that all social-based sites/companies follow the same policy, not so they can resell user content, but so they can eventually go through an acquisition without facing a class action lawsuit from its users who would demand a % of the sale. e.g. Geocities.

True. I have a theoretical physics friend who's now applying a ton of machine-learning techniques to biophysics stuff (in an academic setting).

I've no idea exactly what he's doing other than he's always snowed under and people keep coming back to him for more.

I am still not convinced that such layouts are good for mobile pages. For example the bostonglobe page wont let me zoom at all on my android phone. This is ok as long as the default font size is fine for me, but I often encounter websites where I want to increase the font size.

Actually modern mobile browsers can handle unresponsive layouts quite well, often better than some "responsive" Layouts.

A random 4-word passphrase is more than enough to stop online attacks against high-value targets (e.g. bank accounts) that have any throttling at all.

A random 5-word passphrase with three random characters tossed at the end has better than 82 bits of entropy and will halt offline attacks, at least by non-TLAs, for many years to come.

These are not hard to memorize. What's hard to memorize is 101 different passphrases, many of which you don't use every day, which is why the people actively working to make it easier are focusing on the management problem.
The author does an insertion sort in a linked list, of course that's going to be slow.

For a sorted insert you need to do 2 things: find the right spot for insertion and the insert itself. An insertion sort does this n times.

For a simple array/vector that's:

search: O(n)

insert: O(1)

total takes (O(n) + O(1)) x O(n) = O(n^2)

For a linked list:

search: O(n)

insert: O(n)

total takes (O(n) + O(n)) x O(n) = O(n^2)

There we go, the algorithm takes O(n^2) for both data structures. The theory already proves that a linked list has absolutely no advantage over an array when using this algorithm. On top of that, iterating over a linked list is slower than over an array for various reasons, even thought they are both O(n). So that's where the difference is coming from.

The example he uses is clearly a wrong use case for a linked list, it's plain wrong to conclude that the whole data structure should never be used.
As with normal passwords, you will have people completely disregarding any advice on how a password should look like. People will just slowly learn that having a faulty security system on the web is the same as it is in real life. You don't put a curtain as your front door, and you shouldn't put "Harry Potter" as your passphrase, especially if you are holding a wand in your Facebook photo.

In my case, I use multi-word passphrases with words from a obscure dialect of a tiny European country's language. Being a dialect I grew up with, it has the benefit of being easy to remember, and the obscureness of it means the phrases itself are more or less a random string of characters to any brute-force attack. Not exactly a "best practice" for anyone but myself, but I'm happy with it :).
"People who can code in the world of technology companies are a dime a dozen and get no respect" , I disagree with that, I think you got a lot of respect in a company that is focused on technology. But If you are working into a marketing company in the development team, then yes you will not get much respect..

Jotform was a victim of lax registrar policy and wasn't a seizure by the USG or any of its agencies in any sense.

Using the Internet is a risk. So is crossing the street.

Your single biggest risk in registering a domain name relates to the business practices of the registrar you choose. This has nothing to do with the "nationality" of a TLD.

You also face risks associated with the policy of the TLD you register in, the laws of the local government and the jurisdictions of the registrar, registry and DNS provider you register with.

You also face a myriad of risks associated with the UDRP and various intellectual property law.

You can either worry yourself silly with the boundary cases and outside risks that I see most talked about in recent HN articles or you can cover 99% of your issues by finding yourself a good registrar (one with fair and reasonable policies and practices) operating under a good government (one with fair and reasonable laws and law enforcement practices) and register in a reliable TLD. And then spend the other 23.5 hours in your busy day worrying about running your startup or doing something else useful with your time.
I don't know why the above comment has been down-voted - it's completely fair and valid.

HN works best when downvoting is not used as disagreement. If you don't like McDonalds, fine. But it's clearly true that many people do.
That's not a fair comparison at all! How are you deciding that it's 10-100x less complex than SOTN?
Bookmarking and Tagging with ‘Tagmark’ for Easy Web Navigation.
Those things are pretty consistent in iOS too, if you follow the pretty well laid out conventions. Settings are in the settings app, search is at the top of a list etc.

I guess the difference is with hardware buttons the app has little ability to effectively change the behaviour, whereas with software conventions they can pick and choose what they follow.

Ensuring Validity Confounding Variables
A confounding variable is an extraneous variable that is statistically related to (or correlated with) the independent variable. This means that as the independent variable changes, the confounding variable changes along with it. Failing to take a confounding variable into account can lead to a false conclusion that the dependent variables are in a causal relationship with the independent variable. Take, for example, a study that seeks to investigate the relationship between income levels and test scores. Without controlling for other variables, the study finds that higher income correlates with better test scores and concludes that the two must be directly related. This is a flawed conclusion because there are many lurking confounding variables that may influence this supposedly clear-cut relationship. For example, perhaps individuals at one school received better education than those at another school. Without controlling for the confounding variables of education level and quality of education, the relationship between income level and test scores cannot be assumed.
namecheap primarily operates as a reseller for enom. You'd be subject to 3 layers of policy (registry, registrar, reseller) + ICANN regulation + the laws in the various jurisdictions. Find something cleaner if you are worried about your domains. Complexity can lead to all sorts of finger pointing when something goes wrong. And if that doesn't phase you, be sure you are comfortable with the enom TOS as you'd likely be subject to that as well. (and yes, I"m aware that NC has an accreditation, that said, most of their registrations are held under and managed through enom's accreditation.)
I'd recommend learning something like Python over Lua as it is more widespread and is used in a lot more areas, but that's up to you.

Python can and is used for web development, though if that's what you're interested in then you might find PHP easier to get into.

Fortran is an interesting choice and I understand your reasoning, however I wouldn't put too much time into that right now (up to you, however, just do what you enjoy).

Basically, there are tonnes of choices each with their individual merits. Pick something with a decent community which you enjoy. Python, Perl, PHP, C, C++, Lua, Java, Javascript.. they all suit that perfectly. If you really can't make up your mind, toss a coin and read up on that language for half an hour and if you like it, keep learning :-)

Another thing to add: it's not just about the language. Once you've learnt a language, you need to learn the commonly used libraries/modules. How to decode XML/JSON, how to talk to a database, socket programming, etc, etc. You might find it better to concentrate on those in a language you already know. It's better to be an expert at one language than mediocre at a dozen.

Also, check this out: http://learnpythonthehardway.org/book/advice.html Just found it and it's sound advice.
I have to respect consistency. :)

I find it interesting that the poster mentioned the growth of C# (going from 4th to the 3rd), but didn't mention Objective-C's much larger growth spike (from 8th to 5th place).

To me, that's the bigger story - I imagine all that Objective-C growth is getting targeted squarely at the mobile platforms. That's a lot of dev interest.

I'm sure the OP would agree that a coder in a marketing company would get even less respect as you'll merely be executing their (not that technically challenging) vision.

If on the other hand you're in an industry where your skills as a coder enable those around you to do new things they otherwise would not be able to do, you'll be revered for that.

"if you can't judge someone's intelligence by their writing ability, what possible measure could you use?"

Who says you can judge it by their ability to write? That's assuming the conclusion and not very intelligent where I come from.

Also there are many people who write great but have nothing intelligent to say.
Grammatical deficiencies can be symptoms of conceptual deficiencies. They can also be symptomatic of getting overly excited, or of discussing very conceptually or emotionally difficult topics. They can be symptomatic of lying. They can also signify which social group you belong to, bro.

To give a more specific critique: vocabulary tests are done in a controlled environment, and hence can not be used to judge the correlation of vocabulary with IQ (or g, etc) in any other environment (unless of course someone has studied this problem and published results).

For example, many otherwise intelligent people exhibit vocabulary deficits, working memory deficits, and many other correlates with stupidity when talking to attractive members of the opposite gender. This doesn't mean that they have a low IQ or g-factor.

In this case, since this was a blog post written at what must have been a very difficult time in this poor TSA blogger's career, I don't think we can really say that their vocabulary is highly indicative of intelligence or g-factor.

That said, I do agree that the TSA is run by morons :p

I think it is hard to argue with that.
The real problem of passwords in general is the complete lack of a standard to what a password can be. Basically every service with a login reinvents the whole damn thing with completely arbitrary rules that are incompatible with each other. Minimun and maximun length, case-sensitivity, digits, letters, special characters, spaces.

Ok, after reading a lot about passwords I decide that I'm gonna go with a condensed passphrase more than 10 characters long and with a couple service-contextual caharcters in the end. That oughta keep me safe right? Well, except I have to pick a 6-8 length password that MUST have a number AND a capitalized letter in it!

"People who can code in the world of technology companies are a dime a dozen and get no respect"
Generally in business, those people whose job title is 'programmer' or 'developer' or 'software engineer' get relatively little respect even with lots of experience. (I am 37 years old and programming since 12) Previously I thought the only way out of this is to become a 'manager', which I never really wanted to do... Recently I have discovered 'quantitative finance' which is a quite respected and interesting geek profession (with lots of math, which i like), and I am planning to transition into that in the long term. (Theoretically a relatively smooth transition is possible because there are 'quant developer' jobs out there.)
