  • Bash: Check if file was modified since used in script

    - by Thomas Münz
    I need to check in a script if a file was modified since I read it (another application can modify it in between). According to bash manual there is a "-N" test which should report if a file was modified since last read. I tried it in a small script but it seems like it doesn't work. #!/bin/bash file="test.txt" echo "test" > $file cat $file; if [ -N $file ]; then echo "modified since read"; else echo "not modified since read"; fi I also tried an alternative way by touching another file and using if [ "file1" -nt "file2 ]; but this works only on a seconds accuracy which may under rare conditions not be sufficient. Is there any other bash-inbuilt solution for this problem or I do really need to use diff or md5sum?

  • How do I step through and debug a Scheme program using Dr. Racket?

    - by Thomas Owens
    I'm using the Dr. Racket development environment and the language definition #lang scheme to do work for a course. However, I'm not sure how to best use this tool for debugging. I would like to be able to execute a function and step through it, observing the values of different functions at various points in execution. Is this possible? If not, what is the typical method of stepping through the execution of a Scheme program and debugging it?

  • CSS Padding Issue w/ submit button

    - by Thomas
    This is a dumb problem but I can't seem to set the padding on a submit button properly. No matter what I input for padding, the width and height of the button never changes. Here is the css: .green_submit { color: #fff; background-color: #94c909; border-right: 1px solid #6d9307; border-bottom: 1px solid #6d9307; border-left: none; border-top: none; padding: 25px; } And the HTML: <input type="submit" class='green_submit' value="Validate" /> Any obvious problems here? How can I manipulate the padding on a submit button?

  • Where to start on creating finger swipe navigation trough a list.

    - by Thomas Stock
    Lets say I want to make a control to select any integer number by dragging on a "bar" with numbers: (156 is selected) Mousedown on "159" and dragging towards the left and then doing mouseup changes the control to this: (160 is selected) I've been experimenting for the past 3 hours but I'm inexperienced in Silverlight so I'm having problems getting started. My current guess is I should seperate this into 2 steps: Step 1: Build this control without swiping behavior. Just 2 buttons to go up a number or go down a number Step 2: Replace the buttons by handling mouse events. With my limited knowledge I think I would manage building a crappy control that does this, with very messy xaml and c# and lots of headaches when trying to apply styling and fancy state transitions, but I was hoping some xaml wizards could get me started with the basic approach? Edit: This is an implementation of what I'm trying to achieve in Silverlight: Iphone's datepicker:

  • DLL with JNA error looking up function?

    - by Thomas Nappo
    This is the code in my DLL (C#): http://pastebin.com/Uirn0z2V I have the DLL built and inside both the JDK bin folder along with inside my project. This is the Java code I am using to access with JNA: http://pastebin.com/NffpaEp8 Yet when I run my Java code this happens: Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'Run': The specified procedure could not be found. at com.sun.jna.Function.<init>(Function.java:179) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:391) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:371) at com.sun.jna.Library$Handler.invoke(Library.java:205) at $Proxy0.Run(Unknown Source) at RunPETest.main(RunPETest.java:18) I have no experience with using JNA with custom DLLs or creating DLLs with C#... so I'm stuck here.

  • Tkinter Gui to read in csv file and generate buttons based on the entries in the first row

    - by Thomas Jensen
    I need to write a gui in Tkinter that can choose a csv file, read it in and generate a sequence of buttons based on the names in the first row of the csv file (later the data in the csv file should be used to run a number of simulations). So far I have managed to write a Tkinter gui that will read the csv file, but I am stomped as to how I should proceed: from Tkinter import * import tkFileDialog import csv class Application(Frame): def __init__(self, master = None): Frame.__init__(self,master) self.grid() self.createWidgets() def createWidgets(self): top = self.winfo_toplevel() self.menuBar = Menu(top) top["menu"] = self.menuBar self.subMenu = Menu(self.menuBar) self.menuBar.add_cascade(label = "File", menu = self.subMenu) self.subMenu.add_command( label = "Read Data",command = self.readCSV) def readCSV(self): self.filename = tkFileDialog.askopenfilename() f = open(self.filename,"rb") read = csv.reader(f, delimiter = ",") app = Application() app.master.title("test") app.mainloop() Any help is greatly appreciated!

  • AutoFixture refactoring

    - by Thomas Jaskula
    I started to use AutoFixture http://autofixture.codeplex.com/ as my unit tests was bloated with a lot of data setup. I was spending more time on seting up the data than to write my unit test. Here's an example of how my initial unit test looks like (example taken from cargo application sample from DDD blue book) [Test] public void should_create_instance_with_correct_ctor_parameters() { var carrierMovements = new List<CarrierMovement>(); var deparureUnLocode1 = new UnLocode("AB44D"); var departureLocation1 = new Location(deparureUnLocode1, "HAMBOURG"); var arrivalUnLocode1 = new UnLocode("XX44D"); var arrivalLocation1 = new Location(arrivalUnLocode1, "TUNIS"); var departureDate1 = new DateTime(2010, 3, 15); var arrivalDate1 = new DateTime(2010, 5, 12); var carrierMovement1 = new CarrierMovement(departureLocation1, arrivalLocation1, departureDate1, arrivalDate1); var deparureUnLocode2 = new UnLocode("CXRET"); var departureLocation2 = new Location(deparureUnLocode2, "GDANSK"); var arrivalUnLocode2 = new UnLocode("ZEZD4"); var arrivalLocation2 = new Location(arrivalUnLocode2, "LE HAVRE"); var departureDate2 = new DateTime(2010, 3, 18); var arrivalDate2 = new DateTime(2010, 3, 31); var carrierMovement2 = new CarrierMovement(departureLocation2, arrivalLocation2, departureDate2, arrivalDate2); carrierMovements.Add(carrierMovement1); carrierMovements.Add(carrierMovement2); new Schedule(carrierMovements).ShouldNotBeNull(); } Here's how I tried to refactor it with AutoFixture [Test] public void should_create_instance_with_correct_ctor_parameters_AutoFixture() { var fixture = new Fixture(); fixture.Register(() => new UnLocode(UnLocodeString())); var departureLoc = fixture.CreateAnonymous<Location>(); var arrivalLoc = fixture.CreateAnonymous<Location>(); var departureDateTime = fixture.CreateAnonymous<DateTime>(); var arrivalDateTime = fixture.CreateAnonymous<DateTime>(); fixture.Register<Location, Location, DateTime, DateTime, CarrierMovement>( (departure, arrival, departureTime, arrivalTime) => new CarrierMovement(departureLoc, arrivalLoc, departureDateTime, arrivalDateTime)); var carrierMovements = fixture.CreateMany<CarrierMovement>(50).ToList(); fixture.Register<List<CarrierMovement>, Schedule>((carrierM) => new Schedule(carrierMovements)); var schedule = fixture.CreateAnonymous<Schedule>(); schedule.ShouldNotBeNull(); } private static string UnLocodeString() { var stringBuilder = new StringBuilder(); for (int i = 0; i < 5; i++) stringBuilder.Append(GetRandomUpperCaseCharacter(i)); return stringBuilder.ToString(); } private static char GetRandomUpperCaseCharacter(int seed) { return ((char)((short)'A' + new Random(seed).Next(26))); } I would like to know if there's better way to refactor it. Would like to do it shorter and easier than that.

  • [wxWidgets] How to store wxImage into database, using C++?

    - by Thomas Matthews
    I have some wxImages and I would like to store them into a BLOB (Binary Large OBject) field in a MySQL database. There are no methods in wxImage nor wxBitmap for obtaining the binary data as an array of unsigned char so I can load into the database. My current workaround is to write the image to a temporary file, then load the BLOB field directly from the file. Is there a more efficient method to load and store a wxImage object into a MySQL BLOB field? I am using MySql C++ connector 1.05, MS Visual Studio 2008, wxWidgets and C++.

  • Why does jquery leak memory so badly?

    - by Thomas Lane
    This is kind of a follow-up to a question I posted last week: http://stackoverflow.com/questions/2429056/simple-jquery-ajax-call-leaks-memory-in-ie I love the jquery syntax and all of its nice features, but I've been having trouble with a page that automatically updates table cells via ajax calls leaking memory. So I created two simple test pages for experimenting. Both pages do an ajax call every .1 seconds. After each successful ajax call, a counter is incremented and the DOM is updated. The script stops after 1000 cycles. One uses jquery for both the ajax call and to update the DOM. The other uses the Yahoo API for the ajax and does a document.getElementById(...).innerHTML to update the DOM. The jquery version leaks memory badly. Running in drip (on XP Home with IE7), it starts at 9MB and finishes at about 48MB, with memory growing linearly the whole time. If I comment out the line that updates the DOM, it still finishes at 32MB, suggesting that even simple DOM updates leak a significant amount of memory. The non-jquery version starts and finishes at about 9MB, regardless of whether it updates the DOM. Does anyone have a good explanation of what is causing jquery to leak so badly? Am I missing something obvious? Is there a circular reference that I'm not aware of? Or does jquery just have some serious memory issues? Here is the source for the leaky (jquery) version: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); </script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { $.ajax({ url: '/html/delme.x', type: 'GET', success: incrementCounter }); } function incrementCounter(data) { if (counter<1000) { counter++; $('#counter').text(counter); setTimeout(leakTest,100); } else $('#counter').text('finished.'); } </script> </head> <body> <div>Why is memory usage going up?</div> <div id="counter"></div> </body> </html> And here is the non-leaky version: <html> <head> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/yahoo/yahoo-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/event/event-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/connection/connection_core-min.js"></script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { YAHOO.util.Connect.asyncRequest('GET', '/html/delme.x', {success:incrementCounter}); } function incrementCounter(o) { if (counter<1000) { counter++; document.getElementById('counter').innerHTML = counter; setTimeout(leakTest,100); } else document.getElementById('counter').innerHTML = 'finished.' } </script> </head> <body> <div>Memory usage is stable, right?</div> <div id="counter"></div> </body> </html>

  • NSThread running a class

    - by Thomas Joulin
    Hi, Every the example I find on the internet (including Apple doc) sets the target to self like this : [NSThread detachNewThreadSelector:@selector(threadedTask) toTarget:self withObject:nil]; Since i would like to do a more complex task in background (involving multiple methods), I thought of creating a class Task called like this : Task *task = [[Task alloc] init]; [NSThread detachNewThreadSelector:@selector(main) toTarget:task withObject:nil]; but I wonder, how will be handled the instance variables of my class Task ? in my method main can I safely call methods of my class Task using [self myMethod] and modifying members variables assuming I'm the only thread accessing it ? This way of handling threads seems weird to me, sorry if my question is stupid ^^ Thanks in advance

  • Why doesn't gcc remove this check of a non-volatile variable?

    - by Thomas
    This question is mostly academic. I ask out of curiosity, not because this poses an actual problem for me. Consider the following incorrect C program. #include <signal.h> #include <stdio.h> static int running = 1; void handler(int u) { running = 0; } int main() { signal(SIGTERM, handler); while (running) ; printf("Bye!\n"); return 0; } This program is incorrect because the handler interrupts the program flow, so running can be modified at any time and should therefore be declared volatile. But let's say the programmer forgot that. gcc 4.3.3, with the -O3 flag, compiles the loop body (after one initial check of the running flag) down to the infinite loop .L7: jmp .L7 which was to be expected. Now we put something trivial inside the while loop, like: while (running) putchar('.'); And suddenly, gcc does not optimize the loop condition anymore! The loop body's assembly now looks like this (again at -O3): .L7: movq stdout(%rip), %rsi movl $46, %edi call _IO_putc movl running(%rip), %eax testl %eax, %eax jne .L7 We see that running is re-loaded from memory each time through the loop; it is not even cached in a register. Apparently gcc now thinks that the value of running could have changed. So why does gcc suddenly decide that it needs to re-check the value of running in this case?

  • Changing label color based on current label color in iPhone dev

    - by Matt Thomas
    I am having trouble figuring out the if statement code for changing the color of a UI label based on the current color of the label. For instance, if the label color is currently red and the correct button is pressed, I want the label color to change to black. If the label color is black I want the label color to change to blue. Many thanks for any tips.

  • How can I preview the contents of books sold on Amazon in Internet Explorer 10?

    - by Aceman
    I run 64-bit Windows 7 and have both Internet Explorer 10 and a newly-downloaded copy of Google Chrome. I downloaded the latter when I found that I could not look (preview) the contents of books sold on Amazon (using it "Look Inside" feature) and wanted to try to get a handle on how extensive the problem was (i.e., whether it occurred on other browsers, too). It turns out that this isn't a problem with Chrome. However, I have grown accustomed over the years to IE and would prefer to resolve this problem instead. Here's an example of my attempt to 'Search Inside' a book on sale at Amazon: http://www.amazon.com/Intellectuals-Race-Thomas-Sowell/dp/0465058728/ref=sr_1_1?s=books&ie=UTF8&qid=1382301764&sr=1-1&keywords=thomas+sowell#reader_0465058728 I understand that I can't (as is the case in some technical support websites) add a screen shot (ie. JPG to this), but if I were to describe what this looks like in IE, the area where the text would appear appears as a blank white page with horizontal lines where the text would ordinarily be. I have just examined this posting of mine via Chrome and the contents of the selected page are clearly visible.

  • How to prevent autoplay and run my own app when inserting an USB-Flash drive

    - by Thomas
    when inserting an USB-Flash drive, Windows normally opens the Autoplay dialog that offers to browse the drive or if there are multimedia files it offers to choose an app to open them. We developed a media player that is connected to the USB-Drive and registers itself as Mass Storage Device. What I need is, that when inserting the Player that this Dialog is not shown, but instead my own application is launched. Ideally the application would be on the Flash Drive itself, but as I understood is that Autorun is disabled for USB-Drives. It would be enough if a preinstalled application is launched. I already tried to catch the WM_DRIVE_CHANGE message, but this only works if my application is the top most window, otherwise the Autoplay Dialog is displayed. Best Tom

  • iPhone: Leak with UIWebView loading Office documents. Any ideas how to avoid it?

    - by Thomas Tempelmann
    While there are already quite a few posts about leaks around UIWebView, mine is a bit more special, I believe, and thus deserves its own post here. I see a reproducible large leak every time I load a Office document such as a Word or Excel file. For instance, every time I display a 180KB .doc file, I get a 100KB leak. And that happens with both the simulator and an actual device, running OS 3.1.3. The leak is not visible with the Leaks instrument but only by looking at the malloc instances via the ObjectAlloc instrument. Here's a picture from the instruments trace: I've also made a demo project, UIWebView-Leak.zip, so you can verify this yourself. To see the leak, use the ObjectAlloc instrument, switch to the view where you see individual allocation objects, and sort by size so that you see the large ones in a group, just like in my picture above. Then view a Office document a few times and find the Malloc objects that keep staying "Live" even after the actual UIWebView has been freed. Is this a known bug? Or is there any way I can avoid these leaks? I.e, have you successfully shown Office documents on an iPhone withing getting such leaks? Note: I've reported this as a bug to Apple now, too (ID 7950594) I am still waiting for someone (including Apple) to confirm this as a true leak or show why it isn't (i.e. that I do something wrong or make wrong assumptions)

  • Parse JSON into a ListView friendly output

    - by Thomas McDonald
    So I have this JSON, which then my activity retrieves to a string: {"popular": {"authors_last_month": [ { "url":"http://activeden.net/user/OXYLUS", "item":"OXYLUS", "sales":"1148", "image":"http://s3.envato.com/files/15599.jpg" }, { "url":"http://activeden.net/user/digitalscience", "item":"digitalscience", "sales":"681", "image":"http://s3.envato.com/files/232005.jpg" } { ... } ], "items_last_week": [ { "cost":"4.00", "thumbnail":"http://s3.envato.com/files/227943.jpg", "url":"http://activeden.net/item/christmas-decoration-balls/75682", "sales":"43", "item":"Christmas Decoration Balls", "rating":"3", "id":"75682" }, { "cost":"30.00", "thumbnail":"http://s3.envato.com/files/226221.jpg", "url":"http://activeden.net/item/xml-flip-book-as3/63869", "sales":"27", "item":"XML Flip Book / AS3", "rating":"5", "id":"63869" }, { ... }], "items_last_three_months": [ { "cost":"5.00", "thumbnail":"http://s3.envato.com/files/195638.jpg", "url":"http://activeden.net/item/image-logo-shiner-effect/55085", "sales":"641", "item":"image logo shiner effect", "rating":"5", "id":"55085" }, { "cost":"15.00", "thumbnail":"http://s3.envato.com/files/180749.png", "url":"http://activeden.net/item/banner-rotator-with-auto-delay-time/22243", "sales":"533", "item":"BANNER ROTATOR with Auto Delay Time", "rating":"5", "id":"22243"}, { ... }] } } It can be accessed here as well, although it because it's quite a long string, I've trimmed the above down to display what is needed. Basically, I want to be able to access the items from "items_last_week" and create a list of them - originally my plan was to have the 'thumbnail' on the left with the 'item' next to it, but from playing around with the SDK today it appears too difficult or impossible to achieve this, so I would be more than happy with just having the 'item' data from 'items_last_week' in the list. Coming from php I'm struggling to use any of the JSON libraries which are available to Java, as it appears to be much more than a line of code which I will need to deserialize (I think that's the right word) the JSON, and they all appear to require some form of additional class, apart from the JSONArray/JSONObject script I have which doesn't like the fact that items_last_week is nested (again, I think that's the JSON terminology) and takes an awful long time to run on the Android emulator. So, in effect, I need a (preferably simple) way to pass the items_last_week data to a ListView. I understand I will need a custom adapter which I can probably get my head around but I cannot understand, no matter how much of the day I've just spent trying to figure it out, how to access certain parts of a JSON string..

  • PowerShell script to restart a service

    - by Guy Thomas
    My mission is to press a keyboard sequence, such as Ctrl +Shift +R, to restart a Windows Service. I have a script which works fine in the PowerShell ISE, when launched with administrative privileges. When I try with a PowerShell script it fails due to insufficient Administrative Privileges. It’s galling that I can get it to work with an old-fashioned bat file, but not PowerShell. The root of the problem is that shortcuts to a PowerShell script have their Administrative privileges box greyed out. So far no work-around has overcome this privilege problem. Any ideas?
