  • How to tell if two exe's are the same code-wise?

    - by yumcious
    Is there a way to detect whether two EXE's (compiled from VS.Net 2008 for C++/MFC) do not have any code-level changes between them i.e. for purposes of knowing that there have been no statement changes. This is for compliance purposes when my vendor ships me an exe, ostensibly with no changes made to the code since the last time we tested it. Is there a tool to check that this is so? Cheers

    After reading this article I'm thinking to change my css reset from eric meyer reset to global reset * {margin:0;padding:0} or thinking to use like this only body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, code, form, fieldset, legend, textarea, p, blockquote, th, td, a { border: 0 none; font-family: inherit; font-size: 100%; font-style: inherit; font-weight: inherit; text-decoration: none; vertical-align: baseline; } table { border-collapse: collapse; border-spacing: 0; } li { list-style: none; }

  • How to handle request-wise DB transactions in ASP.NET MVC?

    - by Dario Solera
    I'm using SubSonic 3.0 (SimpleRepository) to handle database access in my ASP.NET MVC 1.0 application. It would be nice to handle a transaction for every web request, committing if everything went smooth and rolling back in case of exception. Is this possible? If so, how? I know this topic has been discussed many times, but I just couldn't find a satisfactory answer. I have built my own solution (create a TransactionScope in the controller, then commit/rollback in OnActionExecuted), but it turns out to be very unreliable.

  • In a web app, is it wise to give log files ".txt" suffix?

    - by Pekka
    I am building a logging mechanism in a web application. Being a Windows man, I tend to give files with textual content the .txt ending. The suffix is automatically registered to be opened in a text editor in any Windows environment, and is just a nice convention. The app is going to be redistributed, and running mostly on Linux, though. The Linux convention for log files is .log. Is there any good reason on the Linux end, besides convention, why I should use .log? Any filters, real-life applications that could become relevant and that will work only with a .log suffix? Or can I merrily call it error_log.txt?

  • Is it wise to rely on default features of a programming language?

    - by George Edison
    Should I frequently rely on default values? For example, in PHP, if you have the following: <?php $var .= "Value"; ?> This is perfectly fine - it works. But what if assignment like this to a previously unused variable is later eliminated from the language? (I'm not referring to just general assignment to an unused variable.) There are countless examples of where the default value of something has changed and so much existing code was then useless. On the other hand, without default values, there is a lot of code redundancy. What is the proper way of dealing with this?

  • Is the moq project dead? Is it wise for me to invest in learning it?

    - by NimsDotNet
    I am fairly new to mocking frameworks and was trying to decide which one will be a good bet to start working on. I have been looking at this question about the best mocking framework, and I can see a lot of people preferring moq, but when i saw the moq project's change list, i can see that it has not been updated for almost an year now. Is moq project dead? if yes, which will be a good mocking framework to start with today?

  • Is it a wise decision to go from dev to third line/Tier 3 dev support?

    - by dotnetdev
    Hi, I am an experienced, mid-level developer. However, I recently spotted a job for a company which is small but has a lot of emphasis on training(beyond the basic technical training, but also mentoring, leadership training, etc). The role is 3rd line so still very technical. It's in app support so it's post implementation development rather than pure out-and-out development like I do now (or don't, as the senior devs do all of the interesting work). However, and this is the question - is this sort of career move common? Also, wouldn't a tech support role be a big shock to the system because I've never dealt with customers? I therefore think it's a bad move? Working in dev, I am used to the lack of customer contact and it is all filtered through by my manager. But in tech support, contacting customers/rude customers could be scary. I don't mind fixing other people's mistakes (better than me making mistakes!) and doing post-implementation dev for production systems (will give me a lot of discipline), and I do get bored sitting in the same place looking/talking to the same people in suits (I work in a corporate environment). The company puts A LOT of emphasis on training and prospects, which I don't get in the current (big) company I work at. Any advice on how to handle tech support is appreciated! Thanks

  • Best way to run multiple queries per second on database, performance wise?

    - by Michael Joell
    I am currently using Java to insert and update data multiple times per second. Never having used databases with Java, I am not sure what is required, and how to get the best performance. I currently have a method for each type of query I need to do (for example, update a row in a database). I also have a method to create the database connection. Below is my simplified code. public static void addOneForUserInChannel(String channel, String username) throws SQLException { Connection dbConnection = null; PreparedStatement ps = null; String updateSQL = "UPDATE " + channel + "_count SET messages = messages + 1 WHERE username = ?"; try { dbConnection = getDBConnection(); ps = dbConnection.prepareStatement(updateSQL); ps.setString(1, username); ps.executeUpdate(); } catch(SQLException e) { System.out.println(e.getMessage()); } finally { if(ps != null) { ps.close(); } if(dbConnection != null) { dbConnection.close(); } } } And my DB connection private static Connection getDBConnection() { Connection dbConnection = null; try { Class.forName(DB_DRIVER); } catch (ClassNotFoundException e) { System.out.println(e.getMessage()); } try { dbConnection = DriverManager.getConnection(DB_CONNECTION, DB_USER,DB_PASSWORD); return dbConnection; } catch (SQLException e) { System.out.println(e.getMessage()); } return dbConnection; } This seems to be working fine for now, with about 1-2 queries per second, but I am worried that once I expand and it is running many more, I might have some issues. My questions: Is there a way to have a persistent database connection throughout the entire run time of the process? If so, should I do this? Are there any other optimizations that I should do to help with performance? Thanks

  • How costly performance-wise are these actions in iPhone objective-C?

    - by Alex Gosselin
    This is really a few questions in one, I'm wondering what the performance cost is for these things, as I haven't really been following a best practice of any sort for these. The answers may also be useful to other readers, if somebody knows these. (1) If I need the core data managed object context, is it bad to use #import "myAppDelegate.h" //farther down in the code: NSManagedObjectContext *context = [(myAppDelegate.h*)[[UIApplication sharedApplication] delegate] managedObjectContext]; as opposed to leaving the warning you get if you don't cast the delegate? (2) What is the cheapest way to hard-code a string? I have been using return @"myString"; on occasion in some functions where I need to pass it to a variety of places, is it better to do it this way: static NSString *str = @"myString"; return str; (3) How costly is it to subclass an object i wrote vs. making a new one, in general? (4) When I am using core data and navigating through a hierarchy of some sort, is it necessary to turn things back into faults somehow after I read some info from them? or is this done automatically? Thanks for any help.

  • How to learn the math behind the code?

    - by Solomon Wise
    I am a 12 year old who has recently gotten into programming. (Although I know that the number of books you have read does not determine your programming competency or ability, just to paint a "map" of where I am in terms of the content I know...) I've finished the books: Python 3 For Absolute Beginners Pro Python Python Standard Library by Example Beautiful Code Agile Web Development With Rails and am about halfway into Programming Ruby. I have written many small programs (One that finds which files have been updated and deleted in a directory, one that compares multiple players' fantasy baseball value, and some text based games, and many more). Obviously, as I'm not some sort of child prodigy, I can't take a formal Computer Science course until high school. I really want to learn computer science to increase my knowledge about the code, and the how the code runs. I've really become interested in the math part after reading the source code for Python's random module. Is there a place where I can learn CS, or programming math online for free, at a level that would be at least partially understandable to a person my age?

  • Reasons to Use Version Control [closed]

    - by Solomon Wise
    Possible Duplicate: I'm a Subversion geek, why I should consider or not consider Mercurial or Git or any other DVCS? What is the value of using version control? I am a relative noob to programming, and am not going to be developing super-good software or even programming professionally anytime soon. With this predicament, is there really any reason to learn git or subversion or any other version control systems?

  • Default documentroot apache does not work

    - by James Wise
    I have apache version 2.2 and php 5.3.15 on a single server. I configured virtual hosting and a default vhost. 0_default_.conf - goes to /var/www/default sub.domain.com.conf - goes to /var/www/sub.domain.com My question is, how could I set the default documentroot to sub.domain.com permanently? That means all request should be redirected to sub.domain.com. I try to remove 0_default_.conf but when viewing the page it display the php source code of sub.domain.com. Here is my configurations -- http://pastebin.com/4e3awUJ4 Although I can create index.php to /var/www/default and permanently redirect to sub.domain.com site but it's not viable solution for me because what if I didn't point the ip address of sub.domain.com to the server so user cannot view that subdomain. I would appreciate if anyone could share their knowledge and wisdom. Thanks. JamesW

  • Did you think I wasn’t going to show up?

    - by Ratman21
    Well Monday was not good for me Job wise or Dare wise. Why? The Census job ended (after only two weeks!). It seems our group was too good at working our blocks and ran out of blocks in our area to work. Out of work again! Well at lest, they gave us a full days pay for Monday. As to dare wise, “Love Is Kind”. As I said, not saying any thing negative was and is easy for me (Love Is Patient).  Kindness is Love in action, no I don’t have problem with doing this (Which is Gentleness, Helpfulness, Willingness or Initiative; well maybe little with the initiative part). It was the dare part “In Addition To Saying Nothing Negative To Your Spouse Again Today, Do At Least One Unexpected Gesture As An Act Of Kindness”. It was the finding or waiting for something I could do.   Well I will keep on trying on that but; will move on to the next day/dare “Love is not selfish”. Stay tuned.

  • What are the drawbacks of Python?

    - by Rook
    Python seems all the rage these days, and not undeservingly - for it is truly a language with which one almost enjoys being given a new problem to solve. But, as a wise man once said (calling him a wise man only because I've no idea as to who actually said it; not sure whether he was that wise at all), to really know a language one does not only know its syntax, design, etc., advantages but also its drawbacks. No language is perfect, some are just better than others. So, what would be in your opinion, objective drawbacks of Python. Note: I'm not asking for a language comparison here (i.e. C# is better than Python because ... yadda yadda yadda) - more of an objective (to some level) opinion which language features are badly designed, whether, what are maybe some you're missing in it and so on. If must use another language as a comparison, but only to illustrate a point which would be hard to elaborate on otherwise (i.e. for ease of understanding)

  • Installing MonoTouch - ibtool not found error

    - by Nic Wise
    I've had Xcode (3.2.1 - SnowLeopard, iphone 3.1.3) installed for a while, and I can run and build apps on it fine. I installed MonoTouch, as I want to leverage the 8+ years of .NET skills I have :) So I installed: Mono: MonoFramework-2.6.1_1.macos10.novell.x86 MonoTouch: monotouch-eval-1.5.0 MonoDevelop: MonoDevelop-2.2.1-r152508 (was 2.2.1, but when I started it up, it said there was an update, which I installed - thats the update version) If I make a new project and build it, I get any of the following errors: Build failed. Object reference not set to the instance of an object. Build failed: ibtool not found (btw, it's in /Developer/usr/bin/ibtool) or a similar one to the second one if I use the older (2.2.1 released) version of MonoTouch. I can't find any debug info anywhere. I could reinstall XCode/iPhone SDK, but as it already is installed and works (and no, this isn't a SL upgrade), it doesn't make sense. Anyone got any ideas? I SO want to use MonoTouch - Obj-C drives me up the wall! Console apps (mono ones) work fine. Mac OS X 10.6.2, Macbook Pro, clean install with old settings moved over.
