- jazh, on 12/07/2007, -0/+56I'm sure paypal will continue to rip us off whatever software they use.
- PoorManBilly, on 12/07/2007, -0/+51Dugg down for submitter not being able to read. They don't run ON mainframes, they run on a Linux cluster that "operates like a mainframe".
- sockpuppets, on 12/07/2007, -5/+54Title should read: Evil Goes Open Source.
- Cubedude04, on 12/07/2007, -4/+34You won't find this in the Highly Reliable Times
- inactive, on 12/07/2007, -3/+28They're not evil, they are just *****. Big difference.
- jacquesm, on 12/07/2007, -3/+24first off, paypal == ebay. second most high volume sites in the world run linux. Client side it is a totally different matter, but unless you like throwing away cash linux is the way to go on the server.
- sirhomer, on 12/07/2007, -3/+24Linux already runs most of the Internet, it would be much more surprising if it was "PayPal chooses Windows to run payment system". Or better "PayPal converts all Windows workstations to Linux". I'm mostly a Linux fan, but this is not impressive.
- sirhomer, on 12/07/2007, -0/+19Yeah well, we run what you run on our $3 Casio calculator running FreeBSD. You should be fired.
- mikewitt, on 12/07/2007, -1/+17$1,571/sec is likely an AVERAGE. AVERAGE != PEAK, AVERAGE < PEAK.
- gudnbluts, on 12/07/2007, -3/+19They can now suck way more securely and reliably than they sucked before.
- thomasprebble, on 12/07/2007, -0/+15Failing that they'll send Steve Ballmer with a chair!
- sockpuppets, on 12/07/2007, -1/+16eBay used to run on a single E10000. I'd walk by their cage and see their guys ripping their hair out as eBay crashed almost daily. A single point of failure like that in a high availability environment is disaster.
- thydzik, on 12/07/2007, -2/+16would have thought paypal processed more then $1,571/sec, seems quite low.
- ZiggityZhang, on 12/07/2007, -4/+17Obviously someone who has never sold anything on eBay.
- drag, on 12/07/2007, -0/+12Mainframes can actually run Linux if your curious. I've done it myself with Redhat on IBM S/390 series mainframes. Although I've haven't done it on a production environment. Instead we have some specialized x86 Suse machines hooked up to the mainframe using fiber S-cons.
If your familar with mainframes then this may not make a whole lot of sense until you understand that it's a effective way to modernize the protocols a IBM mainframe can support. We'll use OS/390, but it works the same for newer stuff. By hooking up Linux it allows you to use a very fast interconnect between the Linux and the IBM legacy OS and it will allow you to run webservers, or NFS, or other such things. A mainframe OS by itself barely has any decent TCP/IP support, much less all the stuff Linux can do.
(btw IBM's virtual machine technology is at least 10 years farther along then anybody else's, including the most high-end VMware stuff. You can run several hundred Linux machines on a single mainframe with almost zero overhead coming from the VM)
For people who are not familar with Mainframes may assume that 'mainframe' is just a big multiple-cpu machine. Anything big is a 'mainframe'. This is not so. A mainframe is a specialized computer with it's roots in the 1960's. Unless you want to spend several million dollars for a single machine your average Core 2 Duo desktop or laptop computer will easily run circles around most mainframes.
In fact users of mainframes will usually intentionally keep their machine's CPU slow.. keep them to a minimal of what they need. The reason they do this is because software and support contracts are charged based on how many 'MIPS' you have. If you have more CPU then you need then you will be paying much to much on software. Therefore mainframes tend to use very optimized custom code for everything and admins will do their best to keep their machine running efficiently at 100% cpu load.
The reason you'd want to use a mainframe is because they are capable of massive amounts of I/O. That is moving lots and lots of information from point A to point B while performing operations on it. Nothing in the PC or server world, outside of super computers, can match a high-end IBM mainframe in terms of the actual bandwidth and types of I/O it can do.
Of course in this article it has _absolutely_nothing_ to do with mainframes.
Mainframes != Big machines.
Mainframes are generally big, but not all are. There are clusters, super computers, big unix iron, big NUMA machines, etc etc. Those are big, but not always, and are not mainframes. - inactive, on 12/07/2007, -1/+13Microsoft cares too.
- computergod, on 12/07/2007, -0/+11The people who's accounts they seized might disagree with you. So there is a picture of a girl in a bikini in one image on your site? Well your running a pornographic site in violation of the TOS then. Expect to get your money taken, and don't expect to get it back without a lawyer.
- cquinnd, on 12/07/2007, -1/+11That doesn't explain the Linux advocates who also mod your comments down...
- shakin, on 12/07/2007, -0/+9The number of transactions means a lot more than the number of dollars. I bet Paypal transactions average a much lower value than most other e-commerce transactions. Things like $5 donations or less are very common.
- phaed, on 12/07/2007, -3/+12schetzowitz oh please tell me why you use that weird format of posting. Where does it come from, why do you do it. Do you not know that no matter what your post says people will generally dislike it?
- shakin, on 12/07/2007, -0/+8Maybe he just mashed the keys and got a url and summary that mostly matched. It's the infinite monkeys thing... finally with all the monkey submissions on digg we got one that sort of makes sense.
- JS9000, on 12/07/2007, -4/+12people who hate microsoft.
- inactive, on 12/07/2007, -8/+15Buddy, there's nothing wrong with being a Linux advocate, but it's even better to be a reasonable, grown up and smart one.
1. It's not windoze, it's Windows or Microsoft Windows. An article with that spelling is not reliable.
2. Yes, financial transactions need to happen on a secure platform, but Windows in the hands of competent people can be a secure and reliable platform, one example is London Stock Exchange with billions of dollars in daily transactions which is Windows + .NET + SQL Server. - STKD, on 12/07/2007, -9/+16Breaking: Linux runs on ______.
World other than Linuxists shrugs indifferently. - arbulus, on 12/07/2007, -2/+9Exactly. They're switching FROM mainframes to Linux servers.
Mainframes are not servers and servers are not mainframes. Two completely different technologies. - PatrickBrown, on 12/07/2007, -1/+8And anyone that does anything with ecommerce realizes this, which makes you wonder:
Is FutureGuy overflowing with ***** or is he simply an idiot in his field?
Why not both? - sirhomer, on 12/07/2007, -1/+7Yeah, right.
According to top500.com, Windows marketshare in supercomputers recently hit 1.25%, up from statistically 0% for six years straight.
2007 is the year of WINDOWS SUPERCOMPUTER - zwaldowski, on 12/07/2007, -2/+7Not gonna happen, buddy.
- sub67, on 12/07/2007, -0/+5$1,571/sec works out to $135,734,400/day or $49,543,056,000/year on average. *shrug* I guess that almost 50 billion/yr in transactions just seems like a lot to me no matter what. What I'd really like to know is the average size of transaction and how many transactions per second it averages. Those monetary figures are just for oohs and aahs while they're in their private jets flying to their private islands in Dubai, or wherever...
- thailand1972, on 12/07/2007, -1/+6Not true:-
http://news.netcraft.com/
Linux runs about half, Microsoft 40% (with MS catching up) - fuzzmeister, on 12/07/2007, -0/+5Not web companies, though.
- mrjit, on 12/07/2007, -1/+6Wow thanks bro, webhosting 101.
- inactive, on 12/07/2007, -0/+4Just look at Google.
- diggduggjoe, on 12/07/2007, -0/+4That is if he is running a business. If, the phones are just his old personal ones, which many people quickly get nice collections of, then they are asking too much.
- zwaldowski, on 12/07/2007, -0/+4I dunno, I still shrug indifferently. They made a good decision.
- arbulus, on 12/07/2007, -0/+4No, the world is ass-raped by Microsoft, who basically own most large corporations by virtue of vendor lock-in.
- voyvf, on 12/07/2007, -1/+5They haven't stolen from me (yet). Yes, they charge transaction fees, but so do merchant banks. It's normal: they take a slice of the pie to get a profit out of letting you use their service. If you don't like it, don't use them.
- arbulus, on 12/07/2007, -1/+4No, they switched from a mainframe to Linux servers.
- mike818, on 12/07/2007, -1/+4The ***** froze my account because i couldn't provide receipts for my cellphones I sold on ebay. Who the hell keeps receipts for inexpensive electronics? They claimed it was a random audit they do. The ironic part is they didn't freeze my ebay account. With the help of paypalsucks.com (I think that was the site) 6 MONTHS later they released my funds. All contact to them had to be through email since the department handling it didn't have a phone number. ProPay has been much better (knock on wood).
- ussoldier, on 12/07/2007, -4/+7No, the title was suppose to read "PayPal Switches to Mac OS X"
Haha, you'll never see that happen... you'll never see anything big run on Mac OS anything... - nastajus, on 12/07/2007, -1/+4They can hate too... ...
- cyssero, on 04/18/2009, -0/+3Great explanation, thanks.
- computergod, on 12/07/2007, -2/+5oops, digg down
- Linh, on 12/07/2007, -0/+3paypal didn't switch anything... they've always been running on a cluster of servers... the guy in charge used to work on mainframes.. that's it.. buried for lame
- fuzzmeister, on 12/07/2007, -1/+4PayPal used to be quite sketchy, but since eBay bought them, they have become much more reliable. They still rip you off with fees, but they aren't going to flat out steal your money anymore.
- ryan83189, on 12/07/2007, -0/+3be thankful it doesn't.
- jrseney, on 12/07/2007, -0/+3Whether or not this site is legit ( I'm hedging on not ) it is just a big ad for http://www.free-merchant.com/ . Come on now, I thought you guys were smarter than that...
- flatfish, on 12/07/2007, -2/+4Scehstowitz has the process automated which explains why these posts all appear within 2 minutes of each other and not only on digg but on Netscape/Propeller and also on Usenet.
In the exact same, difficult to read format.
If you study his comments you'll notice some distinct similarities in other posts.
I'm beginning to wonder if Schestowitz is using ELiza on steroids :) - lochraven, on 12/07/2007, -0/+2Wtf is with the misleading title? This story was retarded - who cares what the CTO thinks. What's that? Micro-computers are versatile?
That's like how someone higher up than me decided that we should phase out our Tandems running Guardian 90 for a rack of Dell's running RHE. So what? It's a cost thing - not because Linux is the end all be all of OS's. Do you know how much spare parts and floor space cost for a Tandem? They do their job just fine though - they haven't been power-cycled in over 10 years, I was still in high school then.
Anyways, I know for a fact PayPal has at least a few Windows servers - they're colo'd at my company's facilities. So, like... take that. - flatfish, on 12/08/2007, -2/+4Very well put!
