  • What is the weirdest language you have ever programmed in?

    - by sfoulk526
    For me, it was Forth, way back at the end of the eighties! Yes, almost prehistory. But I was an un-degree-ed programmer, unable to afford college, self-taught C and Assembly, and not enough experience to open doors. I was invited to work in software engineering, my dream job by the engineering manager of my company, but...I had to do it in Forth, and the company was willing to teach me. The position was my start into embedded systems programming, and man did I learn a lot! Like, just how easy C and Assembly language REALLY could be! But it was a good journey, and though I never coded again in Forth, my fear of not being able to learn C and Assembly proficiently disappeared... ;-)

  • Avoiding jagged text when pasting into vi?

    - by overtherainbow
    Hello Although I have no problem using SecureCRT (5.1.2 build 274) to work from Windows and connect to PC's running Linux, I have a problem when connecting to an embedded Asterisk appliance that provides"vi" through BusyBox 1.4.1 (2008-03-10). The issue I'm having, is that when I paste code into vi, the text appears jagged like this: <?php try { $dbh = new PDO("sqlite:./db.sqlite"); $dbh->exec("CREATE TABLE IF NOT EXISTS customer (id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR(255))"); Does someone what the problem is? Is there a way to reconfigure either BusyBox or SecureCRT so that I can paste successfully? Thank you.

  • Why is it so hard to share resource files (resx) with my Silverlight client?

    - by Jordan
    I'm trying to share a resource file (.resx file) from my web (RIA Service?Silverlight Host) to client (Silverlight) by linking the resource file into my client. When I try to access resources using the ResourceManager object I get the following error: System.Resources.MissingManifestResourceException was caught Message=Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "PPCa.Modules.ProjectManager.Client.ViewModels.ResourceStrings.resources" was correctly embedded or linked into assembly "PPCa.Modules.ProjectManager.Client" at compile time, or that all the satellite assemblies required are loadable and fully signed.

  • How can I merge CSS definitions in files into inline style attributes, using Perl?

    - by mintywalker
    Many email clients don't like linked CSS stylesheets, or even the embedded <style> tag, but rather want the CSS to appear inline as style attributes on all your markup. BAD: <link rel=stylesheet type="text/css" href="/style.css"> BAD: <style type="text/css">...</style> WORKS: <h1 style="margin: 0">...</h1> However this inline style attribute approach is a right pain to manage. I've found tools for Ruby and PHP that will take a CSS file and some separate markup as input and return you the merged result - a single file of markup with all the CSS converted to style attributes. I'm looking for a Perl solution to this problem, but I've not found one on CPAN or by searching Google. Any pointers? Alternatively, are there CPAN modules one could combine to achieve the same result? Ruby http://code.dunae.ca/premailer.web/ PHP http://www.pelagodesign.com/sidecar/emogrifier/ Perl ?

  • make a lazy var in scala

    - by ayvango
    Scala does not permit to create laze vars, only lazy vals. It make sense. But I've bumped on use case, where I'd like to have similar capability. I need a lazy variable holder. It may be assigned a value that should be calculated by time-consuming algorithm. But it may be later reassigned to another value and I'd like not to call first value calculation at all. Example assuming there is some magic var definition lazy var value : Int = _ val calc1 : () => Int = ... // some calculation val calc2 : () => Int = ... // other calculation value = calc1 value = calc2 val result : Int = value + 1 This piece of code should only call calc2(), not calc1 I have an idea how I can write this container with implicit conversions and and special container class. I'm curios if is there any embedded scala feature that doesn't require me write unnecessary code

  • iPhone team dev, do we all need the same OS?

    - by aruwanwan
    I´m just starting iPhone development with a small team of (really young and naive) colleagues, we all are fairly new to OS X, my question is: If we are planning to develop for every iPod Touch/iPhone out there (not the iPad, I read that thing requires Snow Leopard), what problems will we encounter when sharing code (and making commits) if we all have a combination of Leopard and Snow Leopard systems?

  • How to hide keys in application?

    - by WilliamKF
    I have a C++ client/server application where the client and server are my executable. Each time a connection is made between the client and server, I generate a new encryption key for that session and I wish to transmit this session key and encrypt this session key using a static key that is built into both the client and server. However, running strings on my executable reveals the static key. How can I hide the embedded static key in my client and server application so that they are not easily extracted and thus allowing someone to decode my session key.

  • How do I close a form when the ESC key was hit, but only if no Control handled it?

    - by Gabriel
    I have a Form that closes itself when the ESC key is pressed, thanks to KeyPreview, ProcessKeyEventArgs, ProcessCmdKey or whatever. But I have a Control on that form that does very relevant things when ESC is pressed (it hides itself) and the Form should not be closed when that happens. The control uses the KeyDown event and sets the SuppressKeyPress flag to true, but that happens after the aforementioned form key preview, thus having no effect. Is there some sort KeyPostview ? How do I not close the form when a Control has a relevant use of a key hit ? Edit: The control handling ESC is a textbox embedded in a hand-maid ListView. The textbox appears when the user clicks a cell, enabling edition. To validate the new text, ENTER would be nice (that already works, as giving the focus to anything else). To cancel edition, ESC seems most natural.

  • Beginner question about merging in git

    - by wxyz
    I'm 15 and have just started using source control systems to manage my code a little better, so I'm a little new to this stuff. Right now I have this repository: [a]---[b]---[d]---[f] master \ \ [c]---[e] develop I want to wind up here: [a]---[b]---[d]---[f]---[g] master \ / \ / [c]---[e]---/ develop where g is equivalent to performing commits [c] and [e] on [f]. This is git checkout master; git merge develop, right?

  • How do I clear a WebView's content before loading a page?

    - by Mark
    I have an embedded WebView in my Cocoa application in which I load an external web page. Each time the user clicks on a button, the view opens and shows the page. The problem is that the second time the user opens the WebView, the previous page is still visible. Instead I'd like to show a blank/empty page (together with a progress indicator). How can I clear a WebView before loading a new page? The closest solution I could find was to call this: [webView stringByEvaluatingJavaScriptFromString:@"document.open();document.close()"]; Is there a better way to do this? Thanks!

  • NSTextField (Label) Attributed Text: Select

    - by huntaub
    I have a NSTextField Label that has attributed text in it. The color and size are different from the defaults. (The text is a bit larger and green) Now, I need to be able to select the text in the label so as the click the hyperlinks embedded in the attributed text. This works fine; however, when selecting the text the format of the text reverts back to the defaults (a smaller, black font). Is there anyway to stop this behavior so that my styling is preserved when the user clicks (selects text) on a Label?

  • .NET Database application guidance.

    - by Wally
    Hello, I'm stumbling in the data wilderness and feel very lost, so i am asking for help. I have done some database apps in VS (C#) winforms for some time, wpf lately. These are small to medium apps (embedded dbs, a bit of sql server), like a restaurants, cash registers and similar. (15-20 tables) Until now, i have done all my datasets by drag and drop in Visual Studio designer. I spent weeks on web trying to find some complete solution how to write complete solution with typed datasets by hand from scratch (DAL, B.Objects) in hope to learn some architecture patterns along the way, but without success. So, finally question. Can someone recommend me what to learn for this type of applications, maybe move away from datasets , use some ORM ( maybe overkill, i dont know). Point me in some direction please.

  • When to choose C over C++?

    - by aaa
    Hi. I have become a fond of C++ thanks to this website. Before, I programmed exclusively in C/Fortran, thinking that C++ was too slow (not anymore). Is there a reason to write new project purely in C? this is besides obvious things like low-level kernel/system components. What about intermediate things, like communication libraries, for example MPI? Is C still more portable than C++? I have messed with pretty exotic systems, like Cray, but have yet to see non-embedded system without C++. thanks

  • Compact web server with Lua support?

    - by OverTheRainbow
    Hello, I need to find a very compact, cross-platform web server that can run Lua scripts, ie. either a regular web server like Mongoose that will forward queries to a Lua program in eg. FastCGI, or a web server itself written in Lua which will save the need to provide a separate web server. I recently started learning about Lua so am still in the dark about what is available out there, save for the three I came accross: Barracuda Embedded Web Server http://barracudaserver.com/ba/doc/ Xavante - Lua HTTP 1.1 Web server http://keplerproject.github.com/xavante/ Haserl http://haserl.sourceforge.net/ If someone's already done this recently, what solution would you recommend along with any tutorial/article that would get me started? Thank you.

  • No-argument method on window.external is invoked when checking with typeof

    - by janko
    Hi, I am trying to display an HTML page with embedded JavaScript code inside a System.Windows.Forms.WebBrowser control. The JavaScript code is expected to interact with the embedding environment through the window.external object. Before invoking a method on window.external, JavaScript is supposed to check for the existance of the method. If it is not there, the code should invoke a generic fallback method. // basic idea if (typeof(window.external.MyMethod) != 'undefined') { window.external.MyMethod(args); } else { window.external.Generic("MyMethod", args); } However, checking for a no-argument method with typeof seems to invoke the method already. That is, if MyMethod accepts any positive number of arguments, the code above will work perfectly; but, if MyMethod is a no-argument method, then the expression typeof(window.external.MyMethod) will not check for its type but invoke it, too. Is there any work-around to this behavior? Can I somehow escape the expression window.external.MyMethod to prevent the method call from occurring?

  • Simulating a missing gem in Ruby unit tests

    - by ktex
    Is there any way to simulate the absence of a gem for certain unit tests, short of actually uninstalling and then reinstalling the gem during testing? I am writing a command line utility, and want to make sure that my tests cover cases where a user may not have all of the gems that I support. For instance, I am using fsevents — a Leopard-specific package for monitoring filesystem events — that will never be present on other systems, as well as a growl gem that's purely optional.

  • How to make CSS/HTML prototyping faster for engineers without strong CSS skills?

    - by rdeshpande
    I've been developing Ruby on Rails applications for some time, and have often found help to develop generate the templates of HTML with accompanying CSS. However, I'd like to make an attempt at doing this myself. Initial experiments leave me feeling like my process is really slow. I'm writing all my Rails code in VIM, which, with accompanying aliases to run the test suite, is pretty fast for me. However, the back-and-forth between browser/VIM to see new changes seems cumbersome - I'm guessing finding an editor with an embedded browser that constantly sees new changes is ideal for this (any suggestions?) So far I've experimented with Blueprint, which at the onset seems like it will save me a ton of time. However, what other tools have helped you do the PSD-HTML/CSS conversion as fast as you can?

  • Global variable not stable after platform changed.

    - by user350555
    Our embedded system is built on a hw/sw platform made by enea. After the platform updated recently, we found some operations on the global variable keep crashing the system. For example, we have a global map structure holding some data. We can insert/iterate the map once or twice, then the address of the elements in the map suddenly changed to some forbidden addresses like 0x0 or 0x1d, the system just crash. The only different before/after the platform update is : 1) sw part: It's a c++ software and We changed the compiler from diab cc to gcc. 2) hw part: we have a new board, but the cpu is still powerpc405s. I tried every possible way but still can't figure out the reason. Any thoughts?

  • Is Azure an Operating System or a Framework?

    - by Brian Genisio
    MS is calling Azure an Operating System. To me, it feels much more like a framework. I am having a bit of trouble defining the two separately. I have a general intuition, but I am not articulate enough to really say if Azure is really an OS or just a framework sitting on top of Operating Systems.

  • Is NAnt in the dead pool?

    - by Andrew Matthews
    I know NAnt sees frequent use (well, I always use it for my CI builds) but there has been no new official release since December 2007. Is the project receiving active development any more or is it dead-pooled? It worries me that if I carry on using it, and it stops tracking the latest version of .NET, I'll eventually be left with a massive job when it comes to upgrading systems to a version of the framework that it can't build. Has everyone else gone over to some other tool like MSBuild these days?

  • How to Generate Embeddable Widgets, and Return PartialView, JS & CSS as JSONP?

    - by DaveDev
    I found this question which is a great starting point towards creating embedded widgets that enable showing dynamic content on remote sites (i.e. a different domain). One problem I'm having is with the following code: public ActionResult SomeAction() { return new JsonpResult { Data = new { Widget = "some partial html for the widget" } }; } It says Widget = "some partial html for the widget" but this doesn't really mean anything to me. I assume that Widget would contain the HTML representing what the user wants to see on the screen, but How do I get the contents of my Partial View into Widget? Can anyone point me in the right direction? Thanks..

  • Is stack address shared by Heap addresses ??

    - by numerical25
    I read On most operating systems, the addresses in memory starts from highest to lowest. So I am wondering if the heap, stack, and global memory all fall under the same ordering..? If I created... pointerType* pointer = new pointerType //creates memory address 0xffffff And then created a local varible on the stack localObject object would localObjects address be 0xfffffe Or is heap and stack ordering completely different.
