• How to make hudson build only most current build.

  - by MikeU

  Question How do I setup Hudson so that if one person triggers a build, Hudson will put it on the queue and wait lets say 2 minutes, and during those 2 minutes if another build is triggered it will replace the older build on the queue with the new build? This way if there are 2 builds in those 2 minutes, Hudson will only perform the last build.

• C++: type Length from float

  - by anon

  This is kinda like my earlier question: http://stackoverflow.com/questions/2451175/c-vector3-type-wall Except, now, I want to do this to a builtin rather then a user created type. So I want a type "Length" that behaves just like float -- except I'm going to make it's constructor explicit, so I have to explicitly construct Length objects (rather than have random conversions flying around). Basically, I'm going into the type-a-lot camp.

• Dynamically detecting supported configuration and profile in Java ME

  - by Casebash

  How do I dynamically detect what profile/configuration is being used? I know that you can dynamically detect supported classes, but I would be surprised if picking a random class that should only be in a particular profile/configuration were the proper way of doing this.

• How does the live, real-time typing work in Google Wave?

  - by Sudhir Jonathan

  I'm sure Wave doesn't poll the server every millisecond to find out if the other user has typed something... so how can I see what the other person is typing as they type? And without hogging the bandwidth.

• Have you actually convinced anybody to Scala?

  - by Lukasz Lew

  I had limited success myself. I was able to hype a few persons about Scala. But in fact none of them made a meaningful effort to try to switch (usually from Java). I would like to read both success and failure stories here. Both long tries and short ones. My goal is to find ways of presenting Scala to another person, friend, co-worker (not an audience) that will make them want to use this great language.

• Does speed of an C/C++, Windows console application depend on whether the target is 32 or 64 bit?

  Supposing that memory is not an issue does targeting a 64 bit OS make a C/C++ Windows console application run faster? Update: Prompted by a few comments/answers the application involves statistical algorithms (e.g., linear algebra, random number draws etc).

• MYSQL autoincrement a column or just have an integer, difference?

  - by David19801

  Hi, If I have a column, set as primary index, and set as INT. If I don't set it as auto increment and just insert random integers which are unique into it, does that slow down future queries compared to autincrementing? Does it speed things up if I run OPTIMIZE on a table with its primary and only index as INT? (assuming only 2 columns, and second column is just some INT value) (the main worry is the upper limit on the autoincrement as theres lots of adds and deletes in my table)

• find all text before using regex

  - by jeff

  How can I use regex to find all text before the text "All text before this line will be included"? I have includes some sample text below for example This can include deleting, updating, or adding records to your database, which would then be reflex. All text before this line will be included You can make this a bit more sophisticated by encrypting the random number and then verifying that it is still a number when it is decrypted. Alternatively, you can pass a value and a key instead.

• JQuery. Layout is shaking during animation

  - by Andrew Florko

  Hello everybody, JQuery accordion animation (as well as simple hides / shows) looks weird with some browsers (IE, Opera). But Fire Fox and Chrome renders animation perfectly without artifacts. Html layout tends to shake with IE / Opera during animation as if surrounding paddings / margins are changed for small random value. How can I minimize this effect. Is it jquery bug or browsers issue?

• sapply and concurrency in R

  - by JSmaga

  Good afternoon, Somebody asked me a question today and neither did I know the answer nor could I find it in the documentation. This person simply asked me if the sapply function in R was making concurrent calls to the function you want to apply to the list, or if the computation is done sequantially. Does anybody know the answer? What about rapply (the recursive version of this function)? Thanks, Jeremie
