- danglerman, on 10/12/2007, -7/+39easy, they hire aliens

- zboog, on 10/12/2007, -0/+11How do you know he didn't get the job because he couldn't combile binary in his head? I don't think you could know why he didn't end up at Google unless you talked to the interviewer.
- Perigil, on 10/12/2007, -1/+11Just to clarify several things that you might not know (and I seriously hope your room mate did know these things):
- You can't compile "binary", the lowest level of coding you'll ever go is assembler as this is the processor instruction set
- There are no numbers in a string, only characters. A string is a sequence of characters.
What you might have ment is basic elementary binary logic, boolean conditions or even binary calculations as additions, multiplications or exponentiation. And in that case, it's absolutely correct to not accept your mate to google since this is the basic knowledge of every computer science graduate. - AcePincter, on 10/12/2007, -2/+12Will someone please dupe an article telling me why people get so upset when things get duplicated. Do they think that someone is making them read it twice? Or that it isn't as valid/interesting because other people didn't read it the first time?
- alecks, on 10/12/2007, -0/+8Yeah, maybe it was the way he handled his mistake...
- joshfraz, on 10/12/2007, -0/+7that blows my mind. it makes me feel better about them keeping all my data. if google ever offers web hosting i'll be the first to sign up.
- geronimo, on 10/12/2007, -0/+7You laugh but I worked at places that had very expensive (think $20-$100k, no one quite knew) netapp arrays whereas google could do all that by slapping together a bunch of relatively cheap linux boxes. The problem with said employer and others like them was their thinking, they thought 'big, centralized, hunkin' machine'..It's easier to program, you can hire perl weanies with no CS degree and get by. But when you grow so do your costs.
Google's way( decentralized, partioned) is superior and it's the future and it makes sense, hardware is now dirt cheap, if you can just slap cheap hardware together and it works, more power to you. The only problem is it's hard to think in the partitioned way but if you can make it work, you will be better off. - BrianWGray, on 10/12/2007, -0/+6You have to be kidding me?
Did you honestly just state that Google doesn't give back?
Here is one of many notable contributions google makes on a regular basis.
http://code.google.com/summerofcode.html - adam123, on 10/12/2007, -1/+7I love how their "dirt-cheap Linux boxes" are 'only' dual 2GHz xeons with 2Gb RAM and 800Gb space :)

- 01001001, on 10/12/2007, -1/+6How does Google do it? I dunno. Maybe I should Google it...
- tylerni7, on 10/12/2007, -0/+4He linked to the original paper, but for those of us who don't want to read the whole thing, he summarized it nicely for us. If you would rather read Google's full report, it's right there go ahead. But don't come crying back when it's all over your head.
- Benad, on 10/12/2007, -2/+6ZFS already brings most of these features in the newer builds of Solaris and OpenSolaris, and it's already open-source.
- tfizzle, on 10/12/2007, -1/+5You're right. It's so easy to effectively group, filter, and search 10 billion documents.
- ethicalhacker, on 10/12/2007, -1/+4Sounds a lot like a huge internal bittorrent.
- Protoss, on 10/12/2007, -2/+5Haven't they given enough back? They also have their own Ubuntu custom linux distro, but won't release it as it is made specifically for internal use.
- LaminatorX, on 10/12/2007, -0/+3Hire them to build a storage cluster for you, then they'll have to give you the source along with the binary. As it is, they've created a tremendous tool built on free software foundations that gives them a competative advantage over Yahoo, MSN, and whomever else cares to step up. As long as they're not distributing binaries, the GPL doesn't in any way to distribute their source.
As it is, I wish more CIO's recognized that you can do exactly this for in-house projects. Unfounded fear of the GPL allowing competitors to co-opt these kinds of custom tools is exactly the kind of FUD that opponents of F/OSS like to sling. - blackb0x, on 10/12/2007, -1/+4they probably have the same number that applied, were qualified, and accepted the position.
- ThePerchik, on 10/12/2007, -0/+3Here is the link my ex-professor has to the paper about GFS. Really good read. Its the original paper i belive.
http://ebbets.poly.edu/wein/cs623/gfs.pdf - tylerni7, on 10/12/2007, -0/+3I'm guessing they'll release it some time, but they are doing plenty now. When they worked on porting things to Linux, they made several patches to Wine, and they did the same for Ubuntu.

- Linkage155, on 10/12/2007, -2/+5Remmember an article simular to this on the FP, but not the same. Good Read though; Digg +
- nferrier, on 10/12/2007, -3/+5the google fs is good. But it could be better if they released it under a free software licence. I've always thought that it's a kind of suspicious thing about google that they don't do release it; given they built their business on free software and they claim that they want to give something back.
- M2Ys4U, on 10/12/2007, -2/+4They already do... ish: https://www.google.com/accounts/ServiceLogin?service=pages&continue=http%3A%2F%2Fpages.google.com%2F<mpl=yessignups
- blueigloo, on 10/12/2007, -0/+2Wish someone had page 2 mirrored..
- acurism, on 10/12/2007, -1/+3"f they are so smart, how come gmail is always screwed up? How come their search algorithm picks up so much spammy *****?"
If your so smart why don't you try and fix their so called "spammy *****"?
I have never had any issues with any Google products and I use most of them. I don't know what you are referring to? - YourTechSupport, on 10/12/2007, -0/+2I know. Where can I get some dirt-cheap hardware like that? Fry's?
*runs* - tybris, on 10/12/2007, -0/+2"I'm not sure by what you mean by "transparently", "
Then you certainly aren't a computer scientist. - tybris, on 10/12/2007, -0/+2@all
How often do you spend a million dollars to get the world's most creative students to work on an Open-Source project a whole summer? Or are you just mad you didn't get picked... - Mrkamikaze, on 10/12/2007, -1/+3Wow! this is great for Google! but for the 99.9999% of average business IT needs its utterly useless! The came up with a proprietary scheme for their type of business so what.
- blackb0x, on 10/12/2007, -1/+3all of these features except spanning multiple machines transparently
- Trevino, on 10/12/2007, -2/+4Why are people burrying the mirrors?
- kalmi, on 10/12/2007, -0/+1But even google has issues, read this:
http://www.elhacker.net/gmailbug/english_version.htm (Gmail Bug - Full access to someone's e-emails - Bug corrected) - figvam, on 10/12/2007, -0/+1Benad, you clearly are clueless about this whole FS thing.
- yocum, on 10/12/2007, -1/+2Read The Google File System white paper, http://www.cs.rochester.edu/sosp2003/papers/p125-ghemawat.pdf, written by the developers back in 2003. Old news.
- lolox, on 10/12/2007, -0/+1@cheneythedick do you make things up like this in real life? because if you do just drop the "the dick" from your nick we'll now in advance that you are full of BS.
- julielacombe, on 10/12/2007, -0/+1Too bad the article was dugg to death, it was VERY interesting and informative! Maybe Microsoft should be taking advice from google's engineer the next time they plan on making a new file system :)
- Benad, on 10/12/2007, -0/+1I'm not sure by what you mean by "transparently", but ZFS supports adding disks to the pool (as mirror or RAID-Z) while the file system is "live", and of course the block pool can span as many disks and mirrored disk pools as you want. See http://www.opensolaris.org/os/community/zfs/whatis/ and this Flash demo http://www.opensolaris.org/os/community/zfs/demos/basics/ .
- Angostura, on 10/12/2007, -0/+1If you want that, you better release all your software under a new ultra-strict, ultra-free license that compels all users to give modifications back to the community, even when the software is only used for internal projects.
That's much more open than the GPL. Good luck getting anyone to use your software. - guytoronto, on 10/12/2007, -1/+2I just read that, and now my brain hurts.
- abuser, on 10/12/2007, -2/+3>ZFS already brings most of these features in the newer builds of Solaris and OpenSolaris, and it's already open-source.
Yes, GFS is ***** and OSS rules.
Now shut up and go back to ww.google.com and use their GFS. - tybris, on 10/12/2007, -0/+1funny, how that kinda demonstrates the findings of the article...
- tybris, on 10/12/2007, -0/+1Got a point, they're system is probably better adepted than any other (well, actually, it's pretty generic), but all large companies form an IT infrastructure adepted to their needs. I expect most users look at computing as an internet full of home computers, webservers and Google.
- clouseau, on 10/12/2007, -0/+0Hadoop is an interesting open source project inspired by DFS:
http://www.google.com/search?q=hadoop+dfs
http://lucene.apache.org/hadoop/ - modapi, on 10/12/2007, -0/+0Surprise, Google custom-built an environment to do the most important thing they do. The REAL surprise: they got serious PhD's to build a production environment instead of a dorky "lab" model.
Note also that StorageMojo.com recommends Eric Scmidt resign or be fired. This isn't just about compsci coolness - you need to WIN too. Something Bill Gates NEVER lost sight of. - borchard76, on 10/12/2007, -1/+1It's not about numbers, but about relative percentages of applicants hired. 4/5ths rule and all that (eg, if you select 100% of your majority applicants, then you need to hire 80% of your minority applicants). For google, this means that if they hire 10% of their white applicants, then they need to hire 8% of their minority (not combined, but separately).
- sl123000, on 10/12/2007, -0/+0google is amazing...
