  • ede-proj-regenerate does weird things with my Makefile

    - by Xavier Maillard
    Hi, I have created a really basic project (Make) like this: (ede-proj-project "zrm" :name "zrm" :file "Project.ede" :targets (list (ede-proj-target-makefile-program "zm" :name "zrm" :path "" :source '("zrm.c") ) ) ) When doing M-x ede-proj-regenerate RET and M-x compile RET RET (accepting make -k as my compile command), make keeps bailing with a **missing separator error. When editing my Makefile outside of Emacs (with the darn evil vi) and replacing spaces by tabs, it works. Is there anything special I should pay attention in order to have this work ? Regards

  • Looking for books

    - by robblot
    When I was learning Visual Basic.net 2008 I found a book that not only taught the basics but by the end of the book I had developed a fully working database application. Does anyone know where I might find a simular book but using Visual C++?

  • Displaying a list of objects with Views - Drupal

    - by RadiantHex
    Hi folks, I'll briefly explain what I'm trying to do: I need to sort a set of content-types within a paginated page. Also I need to add filtering to the page, for example each content-type should have a set of tags and the filter needs to filter through these tags. This is a basic mockup of what this page consists of: I'm finding it quite hard figuring out the best way to do it, and if this can be done. Help would be very much appreciated!!

  • Account not getting completed deleted within linux

    - by lbanz
    I've got a nas box running some flavour of linux 2.6.31.8.nv+v2 with an arm processor. It has got a samba share called 'all' that has full read write access to everyone. However one Windows machine cannot access it without prompting for authentication and I found out from the logs that the windows account matches a local account on the nas box. What I then went to do is delete the local account on the nas. I can see that /home,/etc/password + /etc/shadow the account doesn't exist anymore. However the samba logs, shows that it thinks it is still there as it says account is disabled. I've tried rebooting both nas + windows box. Is there somewhere else that it stores account information? I logged on with a different account on that Windows machine and I can access the share fine. The smb logs shows that it can't find the user and then allows anonymous access.

  • Ruby: Parse, replace, and evaluate a string formula

    - by Swartz
    I'm creating a simple Ruby on Rails survey application for a friend's psychological survey project. So we have surveys, each survey has a bunch of questions, and each question has one of the options participants can choose from. Nothing exciting. One of the interesting aspects is that each answer option has a score value associated with it. And so for each survey a total score needs to be calculated based on these values. Now my idea is instead of hard-coding calculations is to allow user add a formula by which the total survey score will be calculated. Example formulas: "Q1 + Q2 + Q3" "(Q1 + Q2 + Q3) / 3" "(10 - Q1) + Q2 + (Q3 * 2)" So just basic math (with some extra parenthesis for clarity). The idea is to keep the formulas very simple such that anyone with basic math can enter them without resolving to some fancy syntax. My idea is to take any given formula and replace placeholders such as Q1, Q2, etc with the score values based on what the participant chooses. And then eval() the newly formed string. Something like this: f = "(Q1 + Q2 + Q3) / 2" # some crazy formula for this survey values = {:Q1 => 1, :Q2 => 2, :Q3 => 2} # values for substitution result = f.gsub(/(Q\d+)/) {|m| values[$1.to_sym] } # string to be eval()-ed eval(result) So my questions are: Is there a better way to do this? I'm open to any suggestions. How to handle formulas where not all placeholders were successfully replaced (e.g. one question wasn't answered)? Ex: {:Q3 = 2} wasn't in values hash? My idea is to rescue eval()... any thoughts? How to get proper result? Should be 2.5, but due to integer arithmetic, it will truncate to 2. I can't expect people who provide the correct formula (e.g. / 2.0 ) to understand this nuance. I do not expect this, but how to best protect eval() from abuse (e.g. bad formula, manipulated values coming in)? Thank you!

  • Building a simple cart using object orientated PHP

    - by James
    I've built basic shopping carts with PHP before but in an attempt to get my feet wet with OOP, I'd like to try using that method. I come from a design background but do understand some basics of OOP but would like to see a tutorial or something simple I could base this on. The site is small and the cart functionality required is very standard. Can anyone offer a link to a decent tutorial or article on building a Cart with PHP OOP, a quick google didn't turn up anything decent.

  • Can Android OS be programmed to interface with a external device via the mini-USB port?

    - by user322865
    Basic example, if I bought a chipset with a light socket and bulb soldered to the chipset; then put a USB cable with the mini-USB plug on the end to get plugged into the android phone. Can I write a Java application to turn on/off the light, get the status of the light(on/off) and maybe power a super-small led/bulb with power from the phone itself? Any insight at all would be greatly appreciated. Thank you

  • IIS7 folder permissions

    - by Eanna
    I build a basic WCF service that I now want to host in IIS7 under Windows Server 2008 R2. I added the service as an application under the default web site but whenever i try to run the application I get the following error: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Config Error - Cannot read configuration file due to insufficient permissions The only way I can get this service working is if i choose to "connect as" the server Administrator when adding the service. the "application user (pass-through authentication)" option does not seem to work. Could anyone help me out, I've just started using IIS7 and have no idea what to do... Thanks

  • How to get a physics engine like Nape working?

    - by Glacius
    Introduction: I think Nape is a relatively new engine so some of you may not know it. It's supposedly faster than box2d and I like that there is decent documentation. Here's the site: http://code.google.com/p/nape/ I'm relatively new to programming. I am decent at AS3's basic functionality, but every time I try to implement some kind of engine or framework I can't even seem to get it to work. With Nape I feel I got a little further than before but I still got stuck. My problem: I'm using Adobe CS5, I managed to import the SWC file like described here. Next I tried to copy the source of one of the demo's like this one and get it to work but I keep getting errors. I made a new class file, copied the demo source to it, and tried to add it to the stage. My stage code basically looks like this: import flash.Boot; // these 2 lines are as described in the tutorial new Boot(); var demo = new Main(); // these 2 are me guessing what I'm supposed to do addChild(demo); Well, it seems the source code is not even being recognized by flash as a valid class file. I tried editing it, but even if I get it recognized (give a package name and add curly brackets) but I still get a bunch of errors. Is it psuedo code or something? What is going on? My goal: I can imagine I'm going about this the wrong way. So let me explain what I'm trying to achieve. I basically want to learn how to use the engine by starting from a simple basic example that I can edit and mess around with. If I can't even get a working example then I'm unable to learn anything. Preferably I don't want to start using something like FlashDevelop (as I'd have to learn how to use the program) but if it can't be helped then I can give it a try. Thank you.

  • AIX 7.1 su root password bug?

    - by exxoid
    In our AIX 7.1 machine there is a weird bug we've ran into.. If you are logged into the AIX box via SSH as a regular user and you try to su - you get prompted for the password, lets say our password is "P@$$w0rd23", you can type "P@$$w0rd2ANYTHING" and it will still grant you root. As long as you have "P@$$w0rd2" it will grant you root regardless of what else you specify in the authentication and even though the actual password is "P@$$w0rd23". This seems to be a bug? Anyone see anything like this before? Thanks.

I tried by changing the java source variable like below private String usedFor; ---- @Basic @Column(name = "USE", length = 45) public String getUsedFor() { return usedFor; } /** * @param use * new value for use */ public void setUsedFor(String usedFor) { this.usedFor = usedFor; } and the error is gone...not sure why it was throwing exception for 'use'..too small for variable name :-)

  • Dediced server for all network functions?

    - by Alan
    I want to set up a fictional network configuration for a school in my neighborhood. They have about 50 computers altogether, 2X20 in computer rooms for students and another 10 scattered around for various professors. They should all access the internet through a dedicated Linux router machine. What they would like is to have domain names for those three computer groups. Lab1, Lab2 and Professors. The computers in Lab2 and Lab1 should have static ip and should all be named by numbers. So there should be 1@Lab1, 2@Lab1.... etc. And the Professors network should have a DHCP, with authentication. Is it an ok solution to have all these functions on a single server? (The one which will be used as a router) Do I have to set a local DNS for domain naming? Do the host names for Lab computers have to be set on the clients, or can they be automatically assigned?

  • When should I opt for test driven development?

    - by VJ
    My question is same as the title. I have not done Test driven development yet,I have performed unit testing and I am aware of testing in general but I hear it is much advantageous to follow TDD?. So should I opt for it everytime or are there some preconditions... i just need to know some basic or important requirements when i should opt for TDD. Sorry if this question is too trivial.

  • Library for parsing arguments GNU-style?

    - by Delan Azabani
    I've noticed the basic 'style' of most GNU core applications whereby arguments are: --longoption --longoption=value or --longoption value -abcdefg (multiple options) -iuwww-data (option i, u = www-data) They follow the above style. I want to avoid writing an argument parser if there's a library that does this using the above style. Is there one you know of?
