  • How to draw a graph in LaTeX?

    - by Amir Rachum
    First of all, let me say I'm using LyX, though I have no problem using ERT. Secondly, what is the most simplest way to draw a simple graph like this in Latex? I've seen some documents with graphs and I've seen some examples, but I couldn't figure out how to just draw a simple graph - what packages do I need, etc?

  • BASH Arithmetic Expressions

    - by Arko
    I had used several ways to do some simple integer arithmetic in BASH (3.2). But I can't figure out the best (preferred) way to do it. result=`expr 1 + 2` result=$(( 1 + 2 )) let "result = 1 + 2" What are the fundamental differences between those expressions? Is there other ways to do the same? Is the use of a tool like bc mandatory for floating point arithmetic? result=`echo "7/354" | bc`

  • Big O, how do you calculate/approximate it?

    - by Sven
    Most people with a degree in CS will certainly know what Big O stands for. It helps us to measure how (in)efficient an algorithm really is and if you know in what category the problem you are trying to solve lays in you can figure out if it is still possible to squeeze out that little extra performance.* But I'm curious, how do you calculate or approximate the complexity of your algorithms? *: but as they say, don't overdo it, premature optimization is the root of all evil, and optimization without a justified cause should deserve that name as well.

  • What are the differences and similarities between the .NET languages?

    - by froadie
    I'm trying to figure out how much overlap there is between the different languages of the .NET framework, and what the real differences are. Is there an overlap of libraries/methods/functions...? If I'm googling a question for, say, VB .NET, and C# answers come up, what can I take from the C#-relevant info and what differences/incompatibilities should I look out for?

  • How do I specify a keys password with MSBuild for the purpose of using Hudson?

    - by Brett Ryan
    We have just setup our hudson server to build .NET projects which seems to be working fine, however for projects that require a password when signing the assemblies I can not figure out how to tell hudson what the password is? For us the password is asked the first time a developer checks out the source code and they open with visual studio, how is this stored? Can we just place a secret file somewhere on the server?

  • Determining a transaction fee before an order is processed

    - by Kenji Crosland
    When users make credit card transactions on my web app, I'd like to include the transaction fee on the confirmation page before the user makes the order. The thing is, there are different transaction fees for different cards. Is there a way to determine a transaction fee from the card number? I'm using Rails and ActiveMerchant, but I figure this question was applicable to other languages as well.

  • How do I get the scalaz IDEA live templates working for the symbolic methods?

    - by oxbow_lakes
    Many of the methods in scalaz have symbolic equivalents, such as forever and 8 (of course, I have this the wrong way round, the symbolic methods really have ASCII equivalents). The project contains a live templates XML file for IDEA so these can be auto-completed, I believe by using the forever+TAB shortcut (in the above instance). I can't figure out how to import this live template into IDEA and actually use it, though. How can I do that?
