  • GUI for Dialog-design for WiX

    - by leiflundgren
    WiX is great in that there is no GUI, you just write the installer you want it to be. No fiddling with GUI-wizards! However, drawing GUI is actually one thing I prefer to use a GUI for. So, is there any Dialog-drawing program which exports WiX-data? (I suppose else-wise perhaps I could transform what Visual Studio's forms editor does to WiX-XML.) /L

  • Codeigniter: Checklist for new users & logistics of app

    - by Kevin Brown
    I'm developing my first web-app, and I'm working through logistics. New users (At first login) need to complete a few things before they can use the app fully. For example, they need to complete their profile before they can move on to step 2, which is taking a test. What's the best way to go about creating a "new-user" checklist? I want it to be as simple as possible, coding wise, and as easy as possible for the user.

  • GLOBALS ARE BAAAAAAADDDD!!!!!

    - by Matt
    HOWEVER! would setting the $link to my database be one thing that I prolly should use a GLOBAL scope for? In my setting of (lots of functions)...it seems as though having only one variable that is on the global scope would be wise. I am currently using the functions to transfer it back and forth so that way I do not have it on global...but it is a bit of a hinder to my script. Please Advise, Thank you. Matt

  • How much information does pdb files contain? (C# / .NET)

    - by Silver Dragon
    Is is wise to redistribute the pdb files along with a commercial application? Occasionally, I'm using the stack trace to get a more detailed error reporting logs from the deployed applications; can this functionality be achieved without relying to those files? Also, how much hints of the original source code does these files contain? Would it be easier to reverse-engineer my application using it?

  • Special scheduling Algorithm (pattern expansion)

    - by tovare
    Question Do you think genetic algorithms worth trying out for the problem below, or will I hit local-minima issues? I think maybe aspects of the problem is great for a generator / fitness-function style setup. (If you've botched a similar project I would love hear from you, and not do something similar) Thank you for any tips on how to structure things and nail this right. The problem I'm searching a good scheduling algorithm to use for the following real-world problem. I have a sequence with 15 slots like this (The digits may vary from 0 to 20) : 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 (And there are in total 10 different sequences of this type) Each sequence needs to expand into an array, where each slot can take 1 position. 1 1 0 0 1 1 1 0 0 0 1 1 1 0 0 1 1 0 0 1 1 1 0 0 0 1 1 1 0 0 0 0 1 1 0 0 0 1 1 1 0 0 0 1 1 0 0 1 1 0 0 0 1 1 1 0 0 0 1 1 The constraints on the matrix is that: [row-wise, i.e. horizontally] The number of ones placed, must either be 11 or 111 [row-wise] The distance between two sequences of 1 needs to be a minimum of 00 The sum of each column should match the original array. The number of rows in the matrix should be optimized. The array then needs to allocate one of 4 different matrixes, which may have different number of rows: A, B, C, D A, B, C and D are real-world departments. The load needs to be placed reasonably fair during the course of a 10-day period, not to interfere with other department goals. Each of the matrix is compared with expansion of 10 different original sequences so you have: A1, A2, A3, A4, A5, A6, A7, A8, A9, A10 B1, B2, B3, B4, B5, B6, B7, B8, B9, B10 C1, C2, C3, C4, C5, C6, C7, C8, C9, C10 D1, D2, D3, D4, D5, D6, D7, D8, D9, D10 Certain spots on these may be reserved (Not sure if I should make it just reserved/not reserved or function-based). The reserved spots might be meetings and other events The sum of each row (for instance all the A's) should be approximately the same within 2%. i.e. sum(A1 through A10) should be approximately the same as (B1 through B10) etc. The number of rows can vary, so you have for instance: A1: 5 rows A2: 5 rows A3: 1 row, where that single row could for instance be: 0 0 1 1 1 0 0 0 0 0 0 0 0 0 0 etc.. Sub problem* I'de be very happy to solve only part of the problem. For instance being able to input: 1 1 2 3 4 2 2 3 4 2 2 3 3 2 3 And get an appropriate array of sequences with 1's and 0's minimized on the number of rows following th constraints above.

  • Exact textual representation of an IEEE "double"

    - by CyberShadow
    I need to represent an IEEE 754-1985 double (64-bit) floating point number in a human-readable textual form, with the condition that the textual form can be parsed back into exactly the same (bit-wise) number. Is this possible/practical to do without just printing the raw bytes? If yes, code to do this would be much appreciated.

  • Python vs. Java performance (runtime speed)

    - by Bijan
    Ignoring all the characteristics of each languages and focusing SOLELY on speed, which language is better performance-wise? You'd think this would be a rather simple question to answer, but I haven't found a decent one. I'm aware that some types of operations may be faster with python, and vice-versa, but I cannot find any detailed information on this. Can anyone shed some light on the performance differences?

  • Is switching to PHP 5.3 a good idea?

    - by understack
    I'm using PHP 5.2.11. I've seen that 5.3 version has several backward incompatibility issues and because of that some code might require changes. Since my website is hosted on shared server, many have suggested that those server won't upgrade to 5.3 in near future (probably due to incompatibility issues for many shared users). Would it be wise to develop a new project in 5.3 which would be hosted on shared server?

  • What was the most refreshingly honest non-technical comment you saw?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored procedure, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

  • who wrote 250k unit tests for webkit?

    - by amwinter
    assuming a yield of 3 per hour, that's 83000 hours. 8 hours a day makes 10,500 days, divide by thirty to get 342 mythical man months. I call them mythical because writing 125 tests per person per week is unreal. can any wise soul out there on SO shed some light on what sort of mythical men write unreal quantities of tests for large software projects? thank you.

  • How do Python and PHP compare for ecommerce?

    - by Ibn Saeed
    If I were to start an ecommerce store, which language would you suggest I start with? Python or PHP? And would it be wise to use Python for an ecommerce site in favor of PHP? PHP has lots of shopping carts, both open source and commercial. Is Python the future of Web Development ? Edit: I would like to clear out that i am not asking for Shopping carts solutions and links to them.
