  • How to properly name record creation(insertion) datetime field ?

    - by alpav
    If I create a table with datetime default getdate() field that is intended to keep date&time of record insertion, which name is better to use for that field ? I like to use Created and I've seen people use DateCreated or CreateDate. Other possible candidates that I can think of are: CreatedDate, CreateTime, TimeCreated, CreateDateTime, DateTimeCreated, RecordCreated, Inserted, InsertedDate, ... From my point of view anything with Date inside name looks bad because it can be confused with date part in case if I have 2 fields: CreateDate,CreateTime, so I wonder if there are any specific recommendations/standards in that area based on real reasons, not just style, mood or consistency. Of course, if there are 100 existing tables and this is table 101 then I would use same naming convention as used in those 100 tables for the sake of consistency, but this question is about first table in first database in first server in first application.

  • Generated Word 2007 prints scrunched up

    - by Brad
    Our website generates Word 2007 documents from database data by creating the xml, zipping it and sending it as a MIME attachment. Usually, this works fine. On occasion, the document will look fine on the screen, but not when printed. The letters end up scrunched together. Here is an example. This is a 1 page document, the first page is a scan of the document printed correctly, the 2nd page is a scan of the same document printed with the problem. Here is the original document. Has anyone ever seen anything similar? I cannot figure out if this is a bug in the code that generates our XML, a bug in the printer driver or a bug in Word. Any ideas would be greatly appreciated. Please note that this document does not contain any real data other than public information, but disregard the contents - this is not an official document, and only meant to illustrate our problem.

  • How "healthy" is the haskell community

    - by Asher
    I came across a post where someone wrote something inaccurate about haskell (won't go into it) and he got flammed for it. Which (pleasantly) surprised me. About 3 years ago I read this joke about haskell: All the haskell programmers in the world can fit into a 747 and if that plane were to crash no one would care... or something along those lines. Which brings me to my question: is haskell "mainstream"? Is it mainly used by hobbiest and academics or someone making some serious money from it (which is the true yardstick of how good a language is - just kidding, geez!)?

  • How can I include platform-specific native libraries in the .JAR file using Eclipse?

    - by Martin Wiboe
    Hello all, I am just starting to learn JNI. I have been following a simple example, and I have created a Java app that calls a Hello World method in a native library. I'd like to target Win32 and Linux x86. My library resides in a DLL, and I can call it just fine using LoadLibrary when the DLL is added to the root of my Eclipse project. However, I can't figure out how to get Eclipse to export a runnable JAR that includes the DLL and the .SO file for Linux. So my question is basically; how would you go about creating a project in Eclipse and include several versions of the same native library? Thank you, Martin

  • Python proxy an application

    - by sharvey
    Does anyone know of a library that enables you to run an application inside some kind of sandbox, with virtual mouse and keyboard support. The use case would be to create some kind of visual test runner, that would replay all actions taken during recording and play them back. So far I found autopy, but the fact that it controls the real mouse position is problematic, because it prevents user interaction with other tools (debugger or anything) while running. Cross platform would be nice, but either windows or os x is fine. Python would be ideal but anything that you could create python bindings for would be ok too.

  • Unbuffered subprocess output (last line missing)

    - by plok
    I must be overlooking something terribly obvious. I need to execute a C program, display its output in real time and finally parse its last line, which should be straightforward as the last line printed is always the same. process = subprocess.Popen(args, shell = True, stdout = subprocess.PIPE, stderr = subprocess.PIPE) # None indicates that the process hasn't terminated yet. while process.poll() is None: # Always save the last non-emtpy line that was output by the child # process, as it will write an empty line when closing its stdout. out = process.stdout.readline() if out: last_non_empty_line = out if verbose: sys.stdout.write(out) sys.stdout.flush() # Parse 'out' here... Once in a while, however, the last line is not printed. The default value for Popens's bufsize is 0, so it is supposed to be unbuffered. I have also tried, to no avail, adding fflush(stdout) to the C code just before exiting, but it seems that there is absolutely no need to flush a stream before exiting a program. Ideas anyone?

  • Django, making a page activate for a fixed time

    - by Hellnar
    Greetings I am hacking Django and trying to test something such as: Like woot.com , I want to sell "an item per day", so only one item will be available for that day (say the default www.mysite.com will be redirected to that item), Assume my urls for calling these items will be such: www.mysite.com/item/<number> my model for item: class Item(models.Model): item_name = models.CharField(max_length=30) price = models.FloatField() content = models.TextField() #keeps all the html content start_time = models.DateTimeField() end_time = models.DateTimeField() And my view for rendering this: def results(request, item_id): item = get_object_or_404(Item, pk=item_id) now = datetime.now() if item.start_time > now: #render and return some "not started yet" error templete elif item.end_time < now: #render and return some "item selling ended" error templete else: # render the real templete for selling this item What would be the efficient and clever model & templete for achieving this ?

  • Setting a session variable in Global.asax causes AJAX errors

    - by Fly_Trap
    I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour. If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below. E.g. I have file called JScript.js containing the code: function myAlert() { alert("Hi World"); } And in my Default.aspx file I reference the js with the code: <script src="JScript.js" type="text/javascript"></script> And in the body onload event I call the myAlert() function: <body onload="myAlert()"> And finally in the Global.asax file: Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs) HttpContext.Current.Session("myVar") = "MyValue" End Sub If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads. Why is this?

  • Personal project in Java

    - by Chuck
    My first project in java is going to be a program (eventually I have to create a GUI interface but for now CLI would do) to keep track of my books (something similar to what libraries have only a simpler). I need to be able to insert, update, remove, show all books, update, search(by name or author or date). For the design I was thinking one main class Library which will have all of the above as methods that connect to the db and retrieve the data. Is this approach ok? I realize it's simple but it's my first real project and I would appreciate a little feedback. Also, is it too soon to consider reading up on design patterns and database design ?

  • How could I embed a html/css/js view in a webstart application

    - by phmr
    I would like to use a html/css/js view in my webstart project without requesting all permissions. I figured out that I could use the java HTTPServer to process the requests but I need a way to avoid using real sockets, so that the HTTPServer instantiation doesn't ask for some permission. Do you know any projects that achieve that ? and if not, what should I do to get an HTTPServer completely working locally (without hitting boundaries...) ? edit: maybe an HTTPServer is too much, I maybe only need a HttpHandler..

  • sscanf + c99 not working on some platforms ?

    - by Jane
    When I compile a simple Hello World! program that uses the sscanf function on my local Debian lenny x64, it works. But when I upload the same program to the server running CentOS x86, it will not work. If I do not use sscanf, then the program works on both computers. gcc -std=c99 -O2 -pipe -m32 If I compile it with sscanf but without -std=c99, then it works on both computers. gcc -O2 -pipe -m32 What is the problem with sscanf and c99 on CentOS x86 ? I thought that compiling with the -m32 flag would work on all Linuxes ? (I have limited access to the CentOS server, so I do not have access to error messages.)

  • Microsoft BizTalk Server vNext (after 2009 R2) - Feature Request

    - by Saravana Kumar
    All, This post is not a question; it’s more of asking for feed back and future request. The product team is always looking for feed back to facilitate the future direction of the product. Some of us as BizTalk Server MVP’s/partners get that privilege to work with the product team closely to give our feedback regularly based on our real world experience. But I believe there is a much wider BizTalk community out there working on closed door project that tests the strength of the product to extreme levels. I would like those passionate people to come forward and put their feature request. Let’s use the power of StackOverflow to help us here. We can vote up and down on each feature request, and see what's going to top the chart. I hope this will be a useful exercise. Updated 24th Feb: If you got more than one request, please post it as separate answers. So, its easy to vote against them.

  • Fake Shortcuts in Windows - Is there an API? One for C#?

    - by tyndall
    I'm not sure what they call the fake shortcuts you often see in Windows now. A good example would be the link to any of the Office 2007 programs. You can tell one of these from a regular shortcut because the Target is grayed out and is not a real path. Can you access these through a .NET API? Like ask for the target? or get any of the information stored within it. I think these are somehow related to Windows Installer and Advertised programs.

  • In your experience, what has inspired you to change a fundamental programming tool

    - by Dr J
    A lot of what I am working on is changing the mindset of a community of developers. Moving them from one tool to another, or to picking up a new tool. What are some of the suggested or recommended ways to get a community to pick up a new meme? While we can mandate tool usage, this is a last resort. I would rather have the developers move to any new tools of their own accord. I'm not a programmer, I need to understand why a programmer will move from one tool to another. Edited the title thanks to a fabulous comment! My world runs on Meme's, tipping points, and general pressures. This is why I needed to ask. And clarifying yet more- I am the middle manager needing to plan and manage an implementation and not a sales person.

  • Filter elements in PropertyGrid

    - by serhio
    In System.Windows.Forms there are a PropertyGrid that displays properties of an attached object. Let's say MyTextBox : TextBox. Now, I would like to display on it some MyTextBox properties, say only Size, Location and my custom property Date. More that than, I would like to be able to change the real property names, say "Dimension", "Location" and "Starting Date". I saw two projects on this subject : first and second, but first does not work well(for browsable properties), and the second seems to add an event for each property changes, this is not acceptable.

  • Bounding Boxes for Circle and Arcs in 3D

    - by David Rutten
    Given curves of type Circle and Circular-Arc in 3D space, what is a good way to compute accurate bounding boxes (world axis aligned)? Edit: found solution for circles, still need help with Arcs. C# snippet for solving BoundingBoxes for Circles: public static BoundingBox CircleBBox(Circle circle) { Point3d O = circle.Center; Vector3d N = circle.Normal; double ax = Angle(N, new Vector3d(1,0,0)); double ay = Angle(N, new Vector3d(0,1,0)); double az = Angle(N, new Vector3d(0,0,1)); Vector3d R = new Vector3d(Math.Sin(ax), Math.Sin(ay), Math.Sin(az)); R *= circle.Radius; return new BoundingBox(O - R, O + R); } private static double Angle(Vector3d A, Vector3d B) { double dP = A * B; if (dP <= -1.0) { return Math.PI; } if (dP >= +1.0) { return 0.0; } return Math.Acos(dP); }

  • Javascript - why do I sometimes fail to read file content with GDownloadUrl?

    - by Daj pan spokój
    Hi everybody. I try to read some file with google's GDownloadUrl and it works only from time to time. failure means fileRows == "blah blah" success means fileRows == (real file content) I've noticed, however, that when I cease (with Firebug) the execution on line 3 for a couple of seconds, it succeeds more often. Maybe it is some kind of threading bug, then? Do You guys have any tip or idea? 1 var fileContent = "blah blah"; 2 availabilityFile = "input/available/" + date + ".csv"; 3 GDownloadUrl(availabilityFile, function(fileData) { 4 fileContent = fileData; 5 }); 6 fileRows = fileContent.split("\n");

  • convert string to float without silent NaN/Inf conversion

    - by Peter Hansen
    I'd like convert strings to floats using Python 2.6 and later, but without silently converting things like 'NaN' and 'Inf'. Before 2.6, float("NaN") would raise a ValueError. Now it returns a float for which math.isnan() returns True, which is not useful behaviour for my application. Here's what I've got at the moment: import math def get_floats(source): for text in source.split(): try: val = float(text) if math.isnan(val) or math.isinf(val): raise ValueError yield val except ValueError: pass This is a generator, which I can supply with strings containing whitespace-separated sequences representing real numbers. I'd like it to yield only those fields which are purely numeric representations of floats, as in "1.23" or "-34e6", but not for example "NaN" or "-Inf". Test case: assert list(get_floats('1.23 -34e6 NaN -Inf')) == [1.23, -34000000.0] Please suggest alternatives you consider more elegant, even if they involve "look before you leap" (which is normally considered a lesser approach in Python).

  • HTML text-area editor for code that traps TAB key

    - by Cristi Cotovan
    Hello, I have looked for months now, for JavaScript-based HTML editor I can embed onto my web pages to replace a TEXTAREA, but to enable me to edit CODE in a friendly, closer to a real editor, way. All editors I've tried (RadEditor from Telerik, FCKEditor, TinyMCE, etc etc), do not trap the TAB key, very useful when editing HTML code onto a page, to help format the code properly. I'm not talking about syntax highlighting, as that would be an awesome plus. But I am mainly wondering if there is such an editor. I'd appreciate being pointed in the right direction.

  • Pasting images in TinyMCE on rails app

    - by Sam Kong
    Hi, I found a weird problem with TinyMCE editor. Copying & pasting images from another domain works fine but if the images are on the same domain the path are relative but not correct sometimes. I figured out that the problem is related to the rails URL scheme. Example) Images are copied from http://mydomain.com/index.html page and the real images path is http://mydomain.com/photos/image.jpg. Editor page: http://mydomain.com/posts/new = image path is set as ../photos/image.jpg http://mydomain.com/posts/edit/123 = image path is set as ../../photos/image.jpg So I tried http://mydomain.com/posts/new/ and it worked. How do I solve this problem? Thanks. Sam

  • handle SIGSEGV in Linux?

    - by user303967
    Hi all, I need handle the SIGSEGV in my Linux app. The reason is some clean up(3-partry lib) must be done before generate core-dump. What is more, the clean up must be performed in the context of calling thread, cannot do in signal handler. So I plan in signal handler to pass the control to the calling thread, after the clean up finished, then use raise(SIGSEGV) to generate the core-dump. The real problem seems the signal_handler cannot pass the control to calling thread, no matter I use post_sem or some others. Any idea to handle this case? Possbile to hijack the SIGSEGV, then in SIGSEGV hander return to another thread to perform some clean up? signal(SIGSEGV, signal_handler); signal_handler() { ... post_sem(); ... } calling thread() { wait_sem(); clean_up(); ... }

  • Seemingly useless debugging environment for Android

    - by mikeY
    I've just started debugging my first three line long android app and I can't seem to use the debug tool like I want to. Here's my code: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); int a = 1 / 0; } Now I expect the debugger to halt the thread and show me the line number of statement where the division by zero occurs. No, instead it shows some other method internal to the system for which I have no source. To make the matters worse, there is no exception message either. Prior to this app, I created one which would do something when a button was pressed. If any exception was raised, again no useful line number or exception message would be shown. As of right now, there is no way to debug my app. Any ideas? I'm using the latest SDK along with Eclipse ADT plugin and debugging on a real device (Nexus One).

  • How do I plot the warping of DTW result using gnuplot?

    - by Ekkmanz
    Hello, Right now I have implemented Dynamic Time Warping algorithm for warping two 3D trajectories. Currently, gnuplot is my plotting tool of choice and it works fine when I plot multiple trajectories at a time. However, when I implement DTW one of the real use for plotting tool is to visualize the point warping, like this picture. Currently, the output of my DTW program is two time series in CSV files and another CSV file which indicate the warp (X in series 1 - Y in series 2). Is there any possible way to do that in gnuplot?

  • DateTime Property not firing PropertyChanged event when changed

    - by Brent
    I'm working on a WPF MVVM application and I've got a TextBox on my view that is bound to a DateTime property on the ViewModel. Seems simple enough, but when I clear the text in the TextBox, the property never changes. In fact, it never even fires until I begin typing "4/1..." and then it fires. What can I do to fix this? Obviously I could bind the TextBox to a string property and then update the real property in the setter, but that's a bit of a hack. There's got to be a better way... ViewModel private DateTime _startDate; public DateTime StartDate { get { return _startDate; } set { _startDate = value; OnPropertyChanged("StartDate"); } } View <TextBox Text="{Binding Path=StartDate, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=true}"/>
