CPU and GPU trends over time | There are many architectural differences between CPUs and GPUs that make it difficult to draw the kinds of conclusions suggested by these graphs.Data parallel algorithms with high computation-to-communication ratios, good data locality and low local branch divergence will see these kinds of speedups when rewritten for GPUs. This is an important subset of algorithms, but don't expect GPUs to replace CPUs for more general-purpose computation any time soon. | Thanks for posting this, its an excellent insight.It was interesting when Intel fail to deliver on their roadmap. Here is a link from 2000 where Intel was alleged to be saying 10Ghz by 2011 http://www.geek.com/articles/chips/intel-predicts-10ghz-chip...Which of course lead to the great Multi-core debate (AMD started it, Intel followed with two physical die on a package later to integrate into a single die).Which lead to the great Memory channel bottleneck (Intel was in-order single channel, AMD was multi-channel) and resolution (everyone now is multi-channel).GPUs on the other hand have always had memory bandwidth issues so they went wide, the GPU equivalent of multi-channel, from the start. They also benefit from a feature of graphics which was 'do this same algorithm on all of these texels' which is straight forward to parallelize.And as nuclear weapons designers, and genomic researchers will tell you, GPUs are also useful in doing MIMD simulations.Its less clear what the parallel architecture breakthrough is for OLAP type problems (or parallel file systems as an even easier example) These have lots of operations in parallel but they also have high connectivity of data synchronicity across those parallel threads which, at the moment, brings everything down to earth.Fun times! |

CPU and GPU trends over time | I would have preferred a logarithmic scale for the last graph (http://csgillespie.files.wordpress.com/2011/01/gpu3.png). | If someone figured out how to write regular apps on a GPU (which would amount to parallelizing the app), it could change everything.1. What would be a first step towards this? It seems the big problem is that most code is sequential... and the opportunity is those parts that don't need to be, but just happen to be written that way.2. Perhaps another opportunity is to try to remove the layers that make modern software so slow. Can they be distributed across all pipelines somehow?3. Finally, a radical approach is not to try to convert existing apps, but to think about the whole problem of an app from the very beginning (what inputs will you get, what outputs do you want), and try to write that directly on a GPU. By making it concrete, you might see new tricks, perhaps by redefining the problem (the app's features). |

How to Recruit a Frontend Hero | I don't think so. First of all, a Frontend Hero needs to have design sense, ability to learn quickly, empathy with users, trustworthiness to "fill in the blanks", and the balls to say no to designs or features that are unnecessary, impractical, and time-consuming. What Sebastian Deutsch described is a CSS / Javascript quirks specialist.Additionally, the article never really touched on how to recruit these people - it just lists screening questions to ask during an interview. To recruit a Frontend Hero, you need to hire great designers and create a culture that treats front end engineers as first class citizens.Incidentally, we're doing that at Airbnb right now.
http://www.airbnb.com/jobs/show/8 | Q: What methods do you know to realize columns?
A: cleardiv
clearfix (better one)
WTF? I'd expect floats, faux columns, display: table-* , *-column-count being the answer but get some cleardiv/clearfix instead. I never liked those, especially cleardiv. Often you can do simply reusing next element (#footer {clear:both}), but sometimes that's not enough, alas.In my opinion any competent frontend developer should know these, not enough for the hero. On the other hand, to be able to interview hero you should be at least on that level yourself, which is not the case there, imho. |

Baby Name Predictor | Wow, my dad would have loved to come across a tool like this.My father, in his infinite genius, devised a clever naming scheme for his children (three of us), with the following rules:1. The middle name must be a fairly rare name, so that we might be the only one among friends/peers with the name, but not so unique or strange that we'd be ridiculed.I'm really grateful for this, and I consider the uniqueness (yet normalcy) of my name a huge gift. To this day I've only ever met one other Simon in person. (It's extremely rare in the US, but very popular in the UK I'm told).2. The first name must be fairly common, everyday name, named after someone in the family, as a fallback for us.Then, we were all to be called by our middle names. If we grew up detesting that name[1], we could easily switch to our first name as our primary je m'apelle and nobody in our future would think twice about it.John Nicholas was picked for my brother's first and middle as Nicholas was a "good Greek name" that almost nobody in America used. That was 1987. If you look at Nicholas in this tool you'll see just what happened to that name! (in the 1980's it shot up to over 1% of names and remained that way until after 2000).My dad was kind of bummed, and probably would have picked a different name if he had a bit of accessible clairvoyance. (Remember, pre-internet it was hard to even know that you could find this information out at all. I suspect the data he found in the 1980's, if any, was already years out of date)I'm the only child that didn't follow the rubric because Anthony Simon Sarris makes for a slightly offensive monogram, so my parents switched the order (to Simon Anthony Sarris) and I'm the only child called by his first name.[1] My little brother hated his middle name Morgan for most of his life (a girl's name too, some teasing, etc) so most of his friends call him by his first name. After high-school he appreciates both names.Aside- I do think our kind are more predisposed to obsess over names than most: "There are only two hard problems in Computer Science:
cache invalidation and naming things."
-- Phil Karlton | An interesting and entertaining study. I question the rigour of the prediction claims (they give a single example, though note that they disclaim that it isn't to be taken too seriously), especially given that naming patterns are dramatically changing.The top girl name accounts for about 1% of the gender now, where early in the 1900s it would account for 6%+.You can thank social media for that, and the effect is accelerating. Our awareness of trends nation and worldwide is much more amplified than it was before, and the forces that virally spread something also contribute to suppressing it lest we all look like fools. Add that multiculturalism and the acceptance of the same has greatly aided the entropy of names.I find geographic distribution and name variations far more interesting (though again, this is changing via social media).e.g.http://names.yafla.com/#n=Isabelle,Isabel,Isabell,Isabella&s... |

Backbone.js views done right | Whoa there nellie. Complexity ahoy.Why would you want to have a view that dumps out its HTML as a string? If a string of HTML is all you want, don't use a view, just use a template.But putting that aside for a second ... for this particular example, how about this: render: ->
this.$el.html JST["table_view_template"]()
tbody = this.$el('tbody')
for person in this.collection.models
view = new TableRowView model: person
tbody.append view.render().el
... or if you were in earnest about only needing the raw HTML from the sub-view, how about just rendering the row templates within the table template, making your render function as simple as this: render: ->
this.$el.html this.template people: this.collection | How is the performance when each row gets its own object instantiated, its own template loaded, and its own events attached? What happens when you have 1000+ rows in a scrollable/sortable/filterable table? I tried nested views approach but the performance was lacking in slower PCs when the row count was high.What I prefer to do is the following: class Example.Views.TableView extends Backbone.View
events:
'click td': 'clicked'
rowHtml: ->
x = []
p = $('#person_row').html()
for person in @collection.models
x.push(_.template(p, person))
x.join('')
clicked: (e) ->
id = $(e.target).parents('tr').attr('id')
# handle action for row id
render: ->
# render self view including rowHTML
The template is loaded just once into a variable and filled in each iteration. Only one set of events is attached to the DOM. Only one call is made to DOM to create all the rows, one string merged from HTML array. I still get the benefit of view and subview templates, without the constructor for subview objects being called 1000 times when all I need is the <tr> HTML x 1000. |

The problem is that views are tightly coupled to the model so it's hard to build them up. I just wrote http://modernjavascript.blogspot.com/2012/06/v-in-mvc.html for another post but believe that it could be helpful in this situation. You'd need to actually write a Backbone.controller class and move the logic in to there but then you could create a whole lot of Backbone.Views that were generic and could be hooked up through the Control (I'd also like to see a Backbone.MultiView or something that could take several views in and then re-emit the changes and allow people to add in several small component views in to a large view either for a collection or a model. |

Ask HN: What do you while the automated tests are running? | My guess is that you're testing AR associations all over the place and that the business logic in your models is tightly coupled to AR associations.

JavaScript Promises: There and back again | Broader adoption of JS on the server will only begin after ES6 generators land in Node. Due to the complexity of async code, writing JS on the server is not easy for the average team.As of now, you could use Promises but it is still kind of messy without generators.

Credentials.get({ token })
.then (credentials) =>
User.get({ username: credentials.username })
#With generators
credentials = yield Credentials.get({ token })
User.get({ username: credentials.username })

Mercurial 2.0 has added largefiles extension (older r. are downloaded on demand) | I'm the developer of [git-annex](http://git-annex.branchable.com/) which is AFAIK the closest eqivalant for git. I only learned about the mercurial bfiles extension (which became the large files extension) after designing git-annex.The designs are obviously similar at a high level, but one important difference is that git-annex tracks, in a fully distributed manner, which git repositories currently contain the content of a particular large file. The mercurial extension is, AFAIK, rather more centralized; while it can transfer large file content from multiple stores it can't, for example, transfer a large file from a nearby client that happens to currently have a copy, which git-annex can do (if a remote is set up). This location tracking also allows me to have offline archival disks whose content is tracked with git-annex. If I ask for an archived file, git-annex knows which disks I can put online to retrieve it.Another difference is that the mercurial extension always makes available all the large files for the currently checked out tree. git-annex allows a tree to be checked out with large files not present (they appear as broken symlinks); you can ask it to populate the tree and it retrieves the files as a separate step. This is both more complex and more flexible. For example, I have a git repository containing a few terabytes of data. It's checked out on my laptop's 30 gb SSD. Only the files I'm currently using are present on my laptop, but I can still manage all the other files, reorganizing them, requesting ones I need, etc.git-annex also has support for special remotes, which are not git repositories, but in which large files are stored.

I'm hopeful that git will grow some internal hooks for managing large files that will improve git-annex and also allow others to develop extensions that, perhaps, behave more like the mercurial largefiles extension. I recently attended the GitTogether and this stuff was a major topic of discussion. | Another option available since Mercurial 1.5 is to put the large files in a subversion repository and reference it as a subrepository.http://mercurial.selenic.com/wiki/Subrepository#SVN_subrepos... |

Products like Perforce are a big hit in games precisely because they are really good at handling this specific class of file.It's a shame, because I hate using Mercurial, but this would give me a very strong reason to use it for my game projects instead of Git. |

Ooc: new awesome language with site redesign, guide, and screencast | I'm in language overload at this point. Much more than another language I'd like to see some creative new architectural approaches to problems that are thorny or tedious to solve right now.I mean, if something as simple as applying MVC principles to web development can create a revolution there have to be a lot of other unplucked ideas out there.

Alpha male programmers aren't keeping women out | I'm not sure who is making this argument anyway. Women are naturally attracted to alpha males.I think the truth is quite the opposite. Programming and IT have historically attracted a large number of social rejects, who, despite scoring high on self-evaluated liberalness, have no idea how to talk to women. Whether the individual problem is general awkwardness, sexist beliefs, bitterness towards women, or inability to engage with women or fawning all over them, if half the guys in an IT department have one of these problems then it's going to be a very unwelcoming place to be for a woman.I remember in my undergrad that the ratio of men to women in CS classes created a problem in and of itself as any remotely attractive woman had to fight off all kinds of unwanted attention from a steady stream of unattractive guys. To me it's no surprise that by senior year they had dwindled to a handful. | Now that doesn't mean the underlying problem isn't worth dealing with. It absolutely is! I think that the world of programming could be much more interesting if more women were part of it. I wish I knew how to make that happen. If I find out, I'll be the first to champion it.This may get me a ton of down-votes, but I'm genuinely curious: is the gender gap in programming actually a problem? If so, why? In what ways would the world of programming be more interesting if it was more evenly split between men and women?I'm not trying to sound misogynistic or anything, just haven't thought much about this topic and I'm not sure I understand why it's considered a big problem. Would love to hear people's views. |

Male programmers and computer science programs always seem to love women who express an interest in it. Let's face it, none of us want this to be a male-only profession.However, society does socialize people into gender roles. Women are taught not to go for math (which computer science, at least at an academic level, depends on) and the sciences just as men are taught to forgo sociology. Remember, there are departments that are mostly women at colleges and it's equally telling to ask why there aren't men in those departments - not as a matter of discrimination, but a matter of socialization. Anyway, women tend to be pushed away from certain paths just as men are pushed away from certain paths (while I find nursing to be an admirable profession, what percentage of nurses do you think are male? And I think it's decently clear that from a young age, many of us have the image of doctors being male and nurses being female).It's a big problem in our society, but I don't think that programers and computer science departments are to blame. We train children from very young ages to go into certain roles. Once you're along a path (any path at any point in life) there is a high cost of switching. If you've been pushed away from math and science through high-school, the chance that you can switch that in college is very low. You have to make up a lot of work that the other students already did - and you're throwing away the work you've done on an alternate path. Having not had biology and chemistry in high-school, medicine was simply out of the question for me in college unless I intended to work much, much harder than my fellow students - and the premeds were an over-achieving bunch.And, really, this is more of a problem if you're going toward the science than if you're going toward the social sciences or humanities. Why? At my school, computer science was an 18 course major; nuroscience 21 courses; biochem was up there too. What did you need for history? 8 courses. Sociology? 10. Anthropology? 9. And you could usually take those courses at the same time while the sciences tend to build on each other in a linear fashion to a greater extent.It's harsh. Even if you want to change into a science, sometimes the barrier is too high. We need to do a better job teaching children that it's unacceptable for both genders to forgo science and math. Otherwise, you end up (like me) in a freshmen bio class realizing that you have to learn everything that everyone else knew from high-school without falling behind on this course. And I'd say that the majority would take the path of least resistance and go for something they weren't missing knowledge in. |

Right from the beginning I was pushed away from computers (before I'd even decided what field I wanted to apply myself to) by teachers, career advisers, college lecturers, friends, strangers, employers and sexist colleagues.I remember being 13/14 and sitting down to an 'interview' with a career adviser. We had to answer a series of questions on screen which were supposed to tell us our ideal career. Every time I answered I could see that various computer related careers were climbing up the list, and yet I was told by the chap doing the interview that I should be a vet or a police officer. Neither made much sense to me.My computing teacher in school used to prioritise computer access to the boys for after school 'computer club', and although I did ICT at college (A levels in the UK), lecturers informed me that I would only be able to use the qualifications to get into admin/secretary jobs (boys were told otherwise). I was one of only two girls on my course at college, and the other girl dropped out by the end of the second year due to family pressure. My last boss used to make derogatory remarks about the fact that I was female, and colleagues supported my male colleague over me.It's the attitude from everyone else that women can't and shouldn't get involved with computers that pushes women into other fields.

The author notes that different professions tend to have different distributions of male personality types. Programmers tend towards meek and introverted, lawyers and businessmen more alpha, yet women don't shy away from those fields.This seems to assume that women must magically all have the same personality type and/or no personality selection bias in their career choices. Since women are comfortable going head-to-head with alpha-male lawyers, they therefore should be totally comfortable with geeky programmers. I don't buy it -- all women are not the same, just like all men are not the same.It seems to me that women who become lawyers or businesspeople likely have A-type personalities themselves. Accordingly, they are probably more likely to view competition or confrontation with males in the workplace as a motivating challenge. Women who become programmers are probably, just like male programmers, a bit more introverted and geeky. Accordingly, confrontation/competition with males in the workplace is probably less likely to be motivating, and more likely to be intimidating -- especially when you consider that many "meek" male programmer types tend to drastically overcompensate for insecurity in physical situations with hyper-competitive and vitriolic behavior in virtual environments (I wonder what the gender and programmer/non-programmer ratios are like on 4chan).In other words, just because male programmers don't rank as alpha-males relative to the general male population doesn't mean they don't behave like alpha-males in their own environment, especially relative to the female personality types interested in becoming programmers.My 2 cents. |

Why isn't join.app.net catching on? | I don't think that the main problems are in name / marketing. While these, and price (which is a legit concern) definitely contribute, the whole idea doesn't sit that well with me.First off, what exactly is it? JSON-based message bus PaaS? Paid social network? Appstore? A development platform? "mobile social entertainment provider"? Something else? I understand that they're working off a broad idea, but it would be reasonable IMO for someone to think that they're attempting each of these. The blog posts and join.app.net don't really clarify things too much. I think that a broad roadmap (or something accessible to users, and devs who don't want to read the whole backstory to try to figure it out) would really help here.Next up, the project doesn't really sell me on its benefits. Developers/users can pay to be able to write to a feed that other developers/users pay to be able to access (or can access for free?)? There's some potential for turning it into an app-store type thing, making it free for developers and splitting user revenue (with the example given where app.net takes 50%)? What concrete benefits, as a developer, or user, will I be able to derive from this service, guaranteed, in the near future?All of the questions here are part of the reason that I'm not particularly excited about it. IMO there are some great ideas in there, and it has a lot of potential, but at the moment it seems like it's not too much more than some hand-waving and assertions that Twitter's bad, and that you should pay for an (at current) nearly identical experience because it has a whole lot of potential at some undefined point in the future. When originally pitching the thing Caldwell made some comments about how it's not fair to assume that you can somehow improve your monetization later, but this seems to be almost the same thing in reverse - they've got their monetization down, but they're assuming that they can somehow add the value for users later. Of course, I could be completely misunderstanding what they're doing / trying to do or how they're going about doing it... | This post is obviously quite biased towards join.app.net, which I'm not entirely against but some of the arguments are very weak.> The current price of $50/year for users and $100/year for developers is fair,Not when you have no details over what the service is going to offer, what control you're going to have, and how the price may change in the future.

Peter Sunde arrested in Sweden | From Google translate ...Peter Sunde arrested in SkåneOne of the brains behind the file sharing site The Pirate Bay has been arrested.Peter Sunde, 35, was arrested today in a raid in southern Sweden.- He has been on the run since 2012 , says Carolina Ekéus , press contact at NCIS .Rikskriminalen state that Peter Sunde has been wanted by Interpol and that he is now arrested.- He was arrested for him to serve a prison sentence of eight months. It's about the Pirate Bay case , says Caroline Ekéus .Expressen says that the raid took place at a farm in Skåne Tonganoxie . According to the newspaper shall Polish police and skånsk picket police have participated in the arrest .
Sentenced to prisonPeter Sunde were sentenced for aiding copyright infringement along with two other men in the Svea Court of Appeal in November 2010. Together sentenced Pirate Bay founders in addition to prison to pay damages of around 46 million.In its judgement, the Court of Appeals held that the men through file-sharing site The Pirate Bay " has facilitated illegal file sharing in a way that lead to penalties for those who run the service ."Peter Sunde has repeatedly applied for revision of the Supreme Court , most recently in February this year. He also refers to new cases from the European Court which deals with how to assess aiding and abetting .
"Deeply unhappy 'Peter sundes defender Peter Althin says to Aftonbladet that he still finds it difficult to accept the verdict .- Has a final judgment , you have to enter and serve this . I kväljer them but I still think that the judgement is deeply unfortunate and inaccurate when it comes to him. There was nothing that showed that he had an active part in this as he was sentenced for, says Peter Althin.He says that an open prison now awaits Peter Sunde.- It does not get Kumla Security or something like that.

Understanding Quaternions (2012) | Where the author talks about imaginary numbers being completely "made up" and suggests you shouldn't bother with trying to understand them, I think that's selling them short.Imagine, if you will, trying to explain to the ancient Greeks the idea of a number that can't be written as a division of integers (the irrational numbers). That would have seemed completely "made up" to them, but we don't really see them that way, they just "are". That concept is has since become normalized, in terms of everyday concepts (like the area of a unit circle). Similar situations arise with fractions or negative numbers to some indigenous tribes, etc.I guess what I'm saying is that complex numbers only as fictitious or imaginary as any other set of numbers that we otherwise feel like we have a good handle on. | Not bad, but I find this to be a state of the art explanation of quaternions: http://acko.net/blog/animate-your-way-to-glory-pt2/#quaterni... |

How to make your application viral - A guide to getting users | When I think about social software (which is the context in which "virality" lives, anyway) I think you have to build for three things - in this order:1. Utility - it must be high utility, even if nobody else is in the system.2. Network Effect - As people are drawn into the system, it needs to scale in value more than linearly3. Residual value - Value taken out of the system, sometimes as revenue. Typically ads.I think that it's not good enough to do these alone, however. You must construct something that isn't just viral but that makes it such that the fact that some person is not on the system is PAINFULLY ANNOYING to the actual users of the system. Consider the growth of email, in general: "Please just go sign up for an email address somewhere so I can email you!"If you construct it in this manner, you do not have to spam people. Delicious, which has a lot of users, never emailed anything other than password resets, for example. | I think one thing you're missing is the idea of social validation, or social proof, of your product. Like TallGuyShort said, getting invitation emails is rather annoying, and quite insincere. Users can spot that insincerity in a heartbeat. Sure, you'll rake in some users, but what you want is to create a demand for the product. When I did that whole FluShirts thing, I used twitter to message people, and within seconds I would see them tweet "haha, check out these shirts [flushirts url]." I'm not sure as to what percentage of shirts I sold were because of twitter referrals, but what that did at the very least was introduce my product to others in a genuine manner to potential customers using their friends.Of course, to gain social validation of your product, it needs to be useful and something people will enjoy. There are some counterexamples, like hi5, that are fairly popular and got to that point because of their random email invitations (I don't know who you are Aaron, Britney, and Alexa), and to that, I'm not quite sure what to say. I guess they found a market. But as far as virality goes, in the genuine sense, I think Facebook/Myspace/Twitter beat hi5. |

Chart.js - open source HTML5 charting library | A bit of the shame on the interactivity:"If you are looking to add interaction as a layer to charts, Chart.js is not the library for you. A better option would be using SVG, as this will let you attach event listeners to any of the elements in the chart, as these are all DOM nodes."Most charts are far more useful with rollovers to let the user interpret the data. I'd say this is a must have for most anything where you really are trying to give the user insight into the dataset.Also seems to be a bit of a punt by saying this just isn't possible in Canvas.

I made $200K and PayPal locked my account | From your comments, you had multiple PayPal accounts (disallowed), were in Venezuela, using a US PayPal account, then transferring the funds to a PayPal account in Venezuela, and can't provide a tax ID for the US account. At the same time, you went from zero to hundreds of thousands in payments in just a few months. To PayPal, you likely appear to be a criminal involved in some type of money laundering or tax evasion scheme. I don't know enough about student Visas and international tax agreements to say you aren't actually engaging in tax evasion, perhaps unknowingly.It's not surprising they locked the account and asked for documentation. The tax code pretty much guarantees they would within a year in order to file the 1099-K on your account. This stuff is serious to them, both from a financial (the potential losses if this money disappears because it's not been moving legally) and regulatory fronts (US Patriot Act among others requires banks, like those underwriting your US PayPal account, to be able to accurately identify their customers). This might not be easy to fix. | Sorry to hear about the troubles :(If this wasn't the umpteenth time I've heard this story, I wouldn't say this so pesteringly:To everyone: Stop stop stop stop stop using PayPal.

New Theory on Why Stonehenge Was Built | One of my old Physics teachers was an expert on Stone Henge. Did a lot of original research in the 1980s. From what I recall Stone Henge is actually multiple sites on top of each other, so when someone says "this is what Stone Henge was for" I am skeptical because we're talking an enormous span of time and several re-buildings with no guarantee that all were for the same reason.This article title is slightly misleading. The migration route of Aurochs theory certainly gives an explanation as to why ancient people gathered in this location. But it doesn't give reason for why the specific structures at Stone Henge were built, as people might assume from the title.What I recall from my old teacher, and his work, was that you can pretty clearly demonstrate that the structures were there for observing the sun cycles, as was typical of many megalithic monuments - sun & moon cycles. Most of the other claimed observations can be explained away as statistical artifacts. Given the evidence of burial and the fact such observations would have had religious significance I haven't seen much to challenge the existing understanding of the site.As an aside, I have visited many megalithic sites in the British Isles (many years go). I find them fascinating. One thing that people often remark on is how they're often in the middle of nowhere, but when they were built they were often in clearings in dense forests, but over time as we domesticated animals that would feed on the bark, killing the trees, then eat the new shoots, over many centuries - millennia - we deforested, for example the moors, and the megalithic sites became elegant monuments to a forgotten age, standing proud against a bleak landscape. | > "Researchers think the giant boulders came from a quarry near Marlborough Downs, just 20 miles (32 kilometers) from the iconic site…"One can't help but smile at the "just" there!
