The One App You Need On Your Resume If You Want a Job At Google 205

HughPickens.com writes Jim Edwards writes at Business Insider that Google is so large and has such a massive need for talent that if you have the right skills, Google is really enthusiastic to hear from you — especially if you know how to use MatLab, a fourth-generation programming language that allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, Fortran and Python. The key is that data is produced visually or graphically, rather than in a spreadsheet. According to Jonathan Rosenberg , Google's former senior vice president for product management, being a master of statistics is probably your best way into Google right now and if you want to work at Google, make sure you can use MatLab. Big data — how to create it, manipulate it, and put it to good use — is one of those areas in which Google is really enthusiastic about. The sexy job in the next ten years will be statisticians. When every business has free and ubiquitous data, the ability to understand it and extract value from it becomes the complimentary scarce factor. It leads to intelligence, and the intelligent business is the successful business, regardless of its size. Rosenberg says that "my quote about statistics that I didn't use but often do is, 'Data is the sword of the 21st century, those who wield it the samurai.'"

      I settled on a combination between Python and Perl (depending on if a lot of parsing is necessary or not). But when a lot of data is involved I go for the old fashioned choice of Fortran. It might not be pretty, and it sure as hell isn't the easiest language; but it beats the crap out of everything else when it comes to speed and convenience for parallelisation. People often forget that this is what Fortran was supposed to be good at, and it really is if you take the time to learn how to use it. Throw in Intel's Fortran compiler and a small cluster and you can chew through gigabytes of data at amazing speeds. The only thing it misses is visualisation tools, but you have a few good opensource dataset viewers, and you can always use Matlab or Python when necessary.
    • Looking back at my old Matlab code also makes me cringe a bit about the syntax of that language.

        R syntax is a lot better. In Matlab, the dimensions of a 3D array are Y,X,Z. That's just one of the many papercuts that makes Matlab difficult and unintuitive to use. R makes a hell of a lot more sense to me.

        That being said, R is also very slow. For one project, I used R and ended up having to use a supercomputer (I only needed a few hundred Opertons out of the 4096 available) to get all the work done in time. For a followup project, I rewrote it in C++ and reran all the same stuff in the same period on a Core 2 Duo. R is really that slow.

        But then, R is an interpreted language, so that's not a surprise. And I was able to rewrite my code in C++ because we didn't need any special libraries; if we had, I wouldn't have had the expertise to reimplement it. R is really convenient to use for many things, and it's also faster than Matlab for everything I've tried in both. Matlab is a dog, and the Mac version crashes at the drop of a hat too. I can't believe people pay money for that crap, except that it's pushed on universities, so people get used to it.

          From what I can see R is a lot more heavily used in Google than Matlab. The article's focus on Matlab is odd. Personally, I mostly use Mathematica. That's less because it's ideal (I haven't learned R so I can't compare, really) than because I already know it.

          That said, Google definitely is interested in people who can extract knowledge from data, using whatever tools.

          How experienced are you with R? I ask because, while of course C++ will always be faster than R, such an enormous difference sounds like it might be due to doing things very suboptimally in R. It's really easy to have orders of magnitude difference in performance in R depending on how you do things.

    MatLab is an old, crufty, feature-creeped script engine that I try to hold myself away from as much as I can. As a researcher and academic (got up to post-doc), Matlab is indeed ubiquitous in academia, but it's mostly due to entrenched positions. I see fewer and fewer people using Matlab these days, and that's a good thing.

    Matlab is by all means not a fourth-generation programming language: it is procedural just like Fortran, which it supplanted in academia, but it does not have type-checking as C, it does not have OO support as C++, it does not do away with semicolons as end-of-line markers like Python; true, it has some advance features like OO and some functional programming, but (almost) nobody uses them, and most Matlab code is a horrible cruft made by self-not-so-well-taught academics. There is nothing in Matlab you cannot do better in Python with scipy, numpy, matplotlib and pandas. Or with declarative PLs like Modelica.

    Matlab is also known for outrageous prices, leveraging on the fact their customer base are universities with big pockets and small administrative brains, and large corporations: they split their code base in many small chunks, and for each you need to pay more and more: as the saying goes, In Matlab you cannot do shit unless you buy a licence for the Toilet Paper toolbox.

        This is the reason I like working for Google. I've worked with dozens, perhaps even low hundreds, of engineers over my four years with the company and in that time I only ran into one idiot.

I spent 20 years working in ordinary large enterprises (as a consultant I saw many), and Google is dramatically different. Oh, there is some amount of bureaucracy creeping in.

It's not perfect, but it's the best place I've been, large or small.

    That's the douchiest way of saying "knowledge is power" that I have ever heard.

    I've used Matlab academically for about half a year now, and that most anybody (but for scientists and mathematicians operating solely on huge numeric matrices, maybe) uses it is rather shocking to me. The only good thing I can really say about Matlab is that it's made me a better programmer in _other_ languages. Sometimes when you're forced to do something so horribly wrong, the right way of doing it leaps out at you. It's like being forced to ride a unicycle, and suddenly realizing why the motorcycle was invented. Not to say that it doesn't have some very advanced features; it's not a simple beast by any means and -can- do some amazing stuff, but it seems to do them so.. weirdly, and often ridiculously slowly, that it's got that crufty feeling of legacy software with stuff just stapled on all over it.

    I'm hopeful about http://www.julialang.org/ [julialang.org] the Julia language project and think it's worth at least keeping an eye on in the future.

    • Second this, and mod parent up into the heavens. I have been using Julia for number-crunching ( trial factoring large numbers, finding Fibonacci primes, large matrix multiplication, PageRank on large graphs => eigenvalues on very large matrices ), and Julia is simply brilliant. The two guys behind the project seem to be working day and night, bug fixes are very very fast, speak 1 week. Julia runs on LLVM, is lightning-fast, and has a rather coherent design.

    I've worked in Matlab (doing DSP), but it's one butt ugly language. It's like FORTRAN with braces, and "global" only works sort of half. And its symbolic manipulation feels like an afterthought. Even Javascript is a better language. And for statistics, why not use R?

    Pro tip: if you want to try your hand at Matlab: it's horribly expensive, but there are free clones available: Octave (http://en.wikipedia.org/wiki/GNU_Octave) and Scilab (http://en.wikipedia.org/wiki/Scilab). I prefer the latter, but be sure to check the list of differences with Matlab.

  • I became a consultant recently (applications of machine learning to big data). After 15+ years of working almost exclusively in Matlab, I switched to javascript/nodejs to get a 'real' programming language under my belt, a language relevant to the web. The fact was, unless I was in academia or a big company, I could not afford Matlab.

    Which is interesting, as there is now a slight class barrier for entry to Google ie. you have to have gone to an institution that could afford the licencing.

    And no ... Octave, S

  • The Matlab language has evolved in a questionable way, software licenses are problematic and harming portability, but the biggest deal after having seen it used at various places, is that Matlab code becomes unmaintainable very fast (this is even more true with Simulink, but I won't digress).

    Matlab is 100% good for one thing: accessing already existing Matlab code; which happens when dealing with research papers because students have been fed with free Matlab licenses since a young age.
    Matlab is also good f

  • The quote 'Data is the sword of the 21st century, those who wield it the samurai.' is a bad metaphor. I'll let the cracked authors explain why.

    Samurai Were Actually Embarrassed of Their Swords
    Oh, come on. This, at least, just has to be bullshit. A quick Google image search of "samurai" returns a gazillion results, 99 percent of which depict the famed warriors with sword in hand. There are drawings about them using swords. There are photos. Hell, pajamas, katanas, and weird hairstyles were their whole thing: Samurai damn well lived by the sword. What else did they have?

    Actually ...

    Yes, the samurai did have an ancient tradition centered around a weapon. However, it sure as shit wasn't the sword. In fact, ignore every movie and video game about samurai, because they only carried swords as awkward last resort weapons.

    Kyuba no michi, "the way of the horse and bow," was there centuries before any semblance of Bushido. It's exactly what it says on the tin: Samurai were all about flinging arrows at peasants from horseback. It makes sense, really -- they were professional soldiers, and in that line of business you quickly learn that only idiots fight the enemy at stabbing distance. Bows were revered over swords to the extent that many Japanese nobles actually downplayed their swordsmanship. After all, pointing out how great your sword skills were was basically announcing that you're a terrible archer. And saying "I'm a terrible archer" was more or less like saying "I'm neither a man nor a warrior."

    The introduction of firearms in the 16th century finally killed the samurai supremacy as mounted archers. As they left the battlefield and settled for a new life as bureaucrats and officials, their formerly reviled swords started taking on actual importance as elaborate status symbols. And because bows weren't really an option anymore, the sword became the go-to weapon of the honorable, sword-wielding, bushido following and completely fictional samurai they retroactively invented to feel better about their crummy desk jobs.

    Maybe it's an unintentionally good metaphor. Big data is the new useless but symbolic catchphrase that you use to make your company look modern.

To stay youthful, stay useful.
