Can secondary indexes be compound ?

At this point we almost need to stop saying facebook programs in PHP. I know this was defending PHP, but look at what is happening. Facebook ( big engineering firm, lots of developers and resources ) could not get php to work for them short

I would have loved to see this presentation. Is the actual talk recorded anywhere ?

Speed and size would be the two biggest. The start up time of the JVM and the size of the generated executables ( jar files ) make scala not terribly useful for those small programming tasks ( scripting and such )

Right but if i can convert the java types to be scala code I can use the scala compiler to compile to whatever my target is.

by dkhenry 13y ago
So now I am really wondering. What is the sub java parts of the JVM that need to be implemented to completely free Scala from the JVM ( i.e. what C interfaces are needed to allow scalc to compile to LLVM or comparable VM)

Just tested this on my GMail. None of the tools required to send an E-mail are hidden. In fact you can do it all without even using a mouse if you have shortcuts turned on.

because some functionality was moved and now requires more interaction doesn't mean its objectively worse. If by moving a feature that is very seldom used ( like renaming the subject ) allows you to make common features easier to use t

I like the new interface. I find it easy to use and streamlined. Since we are all talking about our old parents, FWIW my mother (60) found it easier to use the new interface then the old interface. There is really nothing objective that is

No, but it happens, in any school at any degree level there are people who "pass" who shouldn't. Even in my lowly engineering school ( graduating class of Computer Engineers was maybe 30 ) there were a number of people who sh

You know poor candidates can go to great schools, they can even get doctorates. They can also be useless, and the set of skills that make you useful are not necessarily the set that you get from an advanced degree. Also FWIW the part about

Was this man's computer use being charged by the key stroke? I mean I understand using a few abbreviations here and there, but i.c ? At least name your files descriptively. I would avoid using this for realzies if only for the fact tha

So workers written in go are 1000x times faster then workers written in Ruby? It almost seemed from the documentation that the workers were written in Ruby as well.

If they want wider adoption they will need to document extensions. There are tons of extensions out there and I would say most non trivial installation use at least a few of them.
706.
by dkhenry 13y ago
The biggest issue I have had with HHVM is that the extensions are totally undocumented ( not like there is much for the Zend engine ). So trying to port over extension to it is a excersize in futility.

MySQL has a few engines that still have a database level lock ( MyISAM, MEMORY ) and those generally preform better for unbalanced loads ( i.e very read heavy or very write heavy )

Well Color me surprised. Your right. I just used the same license that RethinkDB is licensed under, I didn't see that they had the drivers under a different license. By Tomorrow I will have them updated to APL ( luckily I can do this s

by dkhenry 13y ago
I am biased, but It is a very straight forward implementation building directly on the protobuf interface. It lacks some of the niceties of the interperted drivers, but It is as fast as ( or faster in some cases ) then the official drivers

This is really a dishonest piece. If you didn't pick up on it they are interviewing a group of individuals who are architecting a competing broadband network in Kansas City. You could not find a more biased group of commentators if you

I think the only hope PHP has of continuing development is if someone big like Facebook can add some direction to it. Maybe they will but I think last I checked even they were giving up on using it for much more then a thin veneer to their

I am super excited about getting my board. Not because its some amazing piece of kit ( GPU's are currently better), but I think their architecture will be awesome if they can scale it up.

So that's the exchange side, what about the clearing. As I understand it that's where the bulk of the cost comes from.

by dkhenry 13y ago
You ( like him ) assume that because he see's something at a given point of time, that he can make decision on it. Yes he might see that there is an offer to sell at one exchange that is below the offer to buy at another exchange, but

by dkhenry 13y ago
yes but do they have to clear all the trades or just at the end of a session ? I was under the impression that you could pool your holdings and clear them once instead of for each individual trade. Also I thought exchanges charge for access
718.
by dkhenry 13y ago
As I understand it if you never have your trades "cleared" you never incur any cost. When you trade the price to have the trade cleared through a clearing house is built in. When big firms trade they only need to go to the clearin

by dkhenry 13y ago
This is actually how it was done. A few times a day large orders would be matched and executed. We moved away from it, and I am not sure if its still used at any of the exchanges anywhere.

I would like to point out this was a theoretical operation done by this professor. It looks to me there are a few errors in his conclusions ( specifically about the risk associated with what he was pretending to do, and the nature of market
