The way our apps work we run everything through a broker service, so our Microsoft lady said that we only needed to buy 5 CALs. When she found out that we use those 5 CALs for servicing hundreds of users, she was not happy. But thats what she told us and we have it in writing
@MattBear Interesting. I thought user CALs were totally gone
@MarkHenderson depends... right now we have 12 core's licensed for 3 VM's, thats auctually covers the entire box if we just run everything on the one server
I've been searching on the Internet (Google...) since one week. I am looking for a RAID controller that will do the following :
Work with HD above 2.2TB (if I use a 3TB drive, I can see a 3TB partition in Windows);
It will work with cheap Seagate 3TB ST3000DM001;
It will work on a Gigabyte Z87X...
@MarkHenderson Yeah, that's definitely wrong. SQL licensed via CALs requires a CAL for every user or device that "uses" data from the DB. So if you have 100 users connecting to an application, and that application stores the info in a SQL DB, then you need 100 CALs; not 1 CAL for the App Server.
@ChrisS Except we have 100 users that connect to a broker. The broker then passes the request onto one of 5 threads, and they connect to the SQL Server. I drew her a diagram. Those 5 threads queue all of the requests and serve them to SQL in a first come first serve basis.
It's an odd system, but there is actually no direct communication from the end users application to the database
@Zoredache At your level, the only real options are: have someone remove a downvote from one of your answer, or get an upvote followed by four downvotes...
@MarkHenderson Well here's the stick. If MS busts you on it, you'll probably look good and hard at the cost of switching to Postgres, MySQL, or anything else... And if you do, they get $0.
Hrm, see your answer is the one that pointed out I didn't know how to read, and sent me back to actually read things. But the other answers might be more useful if anyone else comes to look at it in the future....
The site you're linking to has been compromised. It is redirecting visitors to a page which distributes malware (though the page appears to have been taken down).
If you know the owner of the site, you may wish to inform them of the problem.
I never come up with malware during scans, no viruses, but a lot of spying, redirecting, fraud ID theft, terrorism, truly, and I don't understand why.

@Andrew Questions along the lines of "does a product exist that does X, Y, Z exist?" can survive here if framed correctly - if something's actually extremely difficult to find that does those things and the asker has done their research.
Heck, I've asked one.
But, that site as proposed would be nothing but "which router should I buy?" and "what's the cheapest best server?"
Dell offers an add-on hardware card for some of their servers that provides a poor man's RAID1 between two SD cards (one card gets all the reads until it dies, writes are mirrored) for booting a simple OS that has very little write load to the OS storage (ie ESXi) - see here (warning: PDF link).

@ShaneMadden it's certainly a difficult problem to solve, trying to evaluate different pieces of specialised hardware - you (usually) can't just read a comparison review online

Almost every site that I've seen on the SE network contends that Shopping Questions are taboo and off-topic.
Likely this is due to trying to prevent opinionated answers or lengthy discussions back and forth "This rocks!" "Meh, it sucks" "NO, it doesn't!" etc.

@MarkHenderson basically: drop the 6-port vendor-locked NTU & deliver a GPON fibre port for a RSP router to plug into; drop back to 14 (7*dual/redundant) POIs; dump the QoS stuff out of the core network (the NBN doesn't have inherent bandwidth limitations, the QoS is artificial limiting so they can sell unlocks)
@Magellan I was once involved in a government contract. The chain went: Government > Auditor > Large Company > Contractor > Us. By the time we were getting paid, we were still getting paid too much for what we were doing, and except the company immediately above us were doing nothing for their slice of the pie. I shudder to think how much the top of the chain was getting paid
Nobody else in the world is doing the "4 independent ethernet ports + 2 independent POTS ports" thing that the current NBN NTUs are. Sure, it's cool in theory, but horrible in practice. Nobody is going to want the POTS ports for much longer anyway. The security / alarm companys that "need" PSTN? Not compatible anyway!
@MichaelHampton It's a convenient mechanism that crops up in a few places - distributed computing and data aggregation. It can make nice code: (taken from code I wrote to aggregate statistics)
# For a given given test, we now have a set of results 'rset'
# to be aggregated
total_mb = reduce(operator.add, map(lambda x: x.mb, rset))
total_iops,mean_ms = reduce(op_wmean, map(lambda x: (x.iops,x.ms), rset))
global_min = min(map(lambda x: x.min, rset))
global_max = max(map(lambda x: x.max, rset))
# stats.stackexchange.com/q/21999/27767
_,mean_variance = reduce(op_wmean, map(
lambda x: (x.iops,x.std**2), rset
))
_,variance_means = reduce(op_wmean, map(
OK, yes, looking at it, that first line can just be a sum() instead of reduce(...)... heh.
Lambdas are also really nice for refactoring lines of code that do too much work but they don't really need a full function.
@MikeyB Nerp. Never did much JavaScript except to dick with the DOM a leetle bit.
My C tomfoolery was never deep enough to get into concepts like that either. Was just ANSI library stuff, making lists and tooling around with dice games and whatnot.
My C dice game was the best dice pair rolling game of all time! Of all time!!
I let it run for a weekend calculating statistics on number pairs. The PowerPC 603e I had then would probably compare very, very unfavorably to my iPhone's A6
@MichaelHampton Think of it as map -> vector operation on a set of items, reduce -> consolidate a set of items down to a single value/set of values
Came across [Loop Nest Optimization](http://en.wikipedia.org/wiki/Loop_nest_optimization) this morning: "This code would run quite acceptably on a Cray Y-MP (built in the early 1980s), which can sustain 0.8 multiply–adds per memory operation to main memory. A machine like a 2.8 GHz Pentium 4, built in 2003, has slightly less memory bandwidth and vastly better floating point, so that it can sustain 16.5 multiply–adds per memory operation. As a result, the code above will run slower on the 2.8 GHz Pentium 4 than on the 166 MHz Y-MP!"
@MichaelHampton Oh, and op_wmean is a weighted mean operator designed for reduce:
def op_wmean( (w1,v1), (w2,v2) ):
'''Returns weighted mean of T1, T2 where each T-value is (weight,value)'''
return (w1+w2),(float((w1*v1 + w2*v2)) / (w1+w2))
The following command: C:\Data\Websites\AJGrant\FBZip\FBZip.exe -e -p "c:\temp\684540A5C01D4CA4A7D1958AE18001EB.zip" "c:\temp\EFD6ED46C8FC4334B4EA9E2045E36502"
Works FINE when I paste it into powershell
It does NOT work when I paste it into CMD
Its not even a powershell command
Fuck it, never mind. My powershell is open as administrator and my cmd isn't
@MattBear I'd say so, I have an Apache server handling a php heavy app with 300 simultaneous visitors and up to 10 page views a second on a 4GB piece of metal and it's nowhere near swapping.
@MichaelHampton And to think I almost contracted out to a Magento development house to wrangle their cloud sprawl (they wanted 20-something $ per hour. Haw.) =P
@MichaelHampton I laughed at them, but they also laughed at me when I suggest no less than double that for a full work week for six months to wrangle.
I'm sad I even suggested $50 an hour for a 1,000 hour contract possibility, but when they were shocked at that price, I knew they needed to go play in traffic.
@MattBear not exactly... you can supposedly just point the supported DFS bits of Samba at a clustered filesystem and it "just works", but I've not tried it
@MattBear If you're talking about MaxClients and "doing it right", the answer is probably no... But doing it "right" takes a lot more time than throwing more RAM at the problem.
@MattBear Depends on the size of your cluster. large systems will typically take down a set of servers, upgrade them (test, etc), and then atomically swap out the old for the new. Then take the old ones and upgrade them as well.
@tylerl unfortunately we aren't that sophisticated, right now it's one VM hosting multiple sites, testing is done on a staging VM, when the code's approved, the dev pushs it to production over FTP
@MattBear The way I set it up at Discourse, the jenkins job turns off an application server at haproxy, pushes the code to it, then turns it back on. Rinse and repeat.
It would be nice to make it more or less atomic, but fucking ruby on rails takes like 20 seconds for an app server to start up. OK, maybe not 20... but much bigger than epsilon.
@MattBear Pull the server out of the cluster, upgrade it using any file-copy mechanism feels appropriate, restart necessary services, re-insert into cluster.
@MattBear Naw, actually put it on both servers, but that takes time right? So upload it at your convenience, then switching to the new code just changes the 'production' symlink to point to the new tree - an "instant" operation.
Ideally what I want is a hot swap production/staging environment, 2 farms, 1 proxy, production and staging are swapped via a console at the proxy, essentially staging vhost is updated and tested, then promoted with a single click that swaps the IP's in the proxy

@Andrew "The problem is I just added a new migration on my rails app and if I run rake db:migrate I am updating the tables/schema on my local development database." lolwut?
@tylerl Yeah, it'll need to already exist, whether it's a file or a device.
@tylerl yeah, he just says tmp instead of tmp=ext4. Really, who cares if the filesystem goes down hard, may as well use ext2. Oh, and yes, a file will become a block device.
> Cryptsetup is usually used directly on a block device (disk partition or LVM volume). However, if the device argument is a file, cryptsetup tries to allocate a loopback device and map it into this file.
"NOTES ON LOOPBACK DEVICE USE" from the Ubuntu manpage for cryptsetup... so yeah.
> If the snapshot logical volume becomes full it will be dropped (become unusable) so it is vitally important to allocate enough space. The amount of space necessary is dependent on the usage of the snapshot, so there is no set recipe to follow for this. If the snapshot size equals the origin size, it will never overflow.

@Andrew Oh, sure. You get triple-word-score for just installing Joomla at all. But it takes a special kind of person to say "I need a nice solid CMS engine to run on IIS7. I know, JOOMLA!"
And when people say, "PHP is a perfectly fine language, look at how many people use it." Now you can point and say "yeah, and they install Joomla on Windows". Perfectly reasonable indeed.
We had a server that we let people install stuff like Mambo and Joomla on, once. Then it started hosting Bank of America, botnet C&C, fun stuff like that
The best argument WRT PHP is the rise and popularity of PHP-based web framework (CI,Cake,etc). And you say, ruby has rails, C# has ASP.NET [MVC], python has django. Why can't PHP have CakePHP?
And the answer is, because PHP is a web framework. The mere existence of the 3 dozen PHP-based web frameworks shows that the language is particularly crappy at the only thing it was built to do.
