  • Does OS X support linux-like features?

    - by Xeoncross
    I have been using XP for almost a decade. Contrary to popular belief, it has served me well. In the last 4 years I don't remember ever having it crash on me. It has the most stable GUI I have ever used. However, an OS is only as good as it's GUI AND command line combined. Windows command line is awful and totally useless. So I have been using Ubuntu for a couple years and Debian on my servers. The only problem is that Gnome applications (ubuntu 6-10) constantly crash on me (Ubuntu Studio was the most unstable OS I ever used). I have high quality Gigabyte, MSI, and Asus motherboards and CPU's from old Semprons/Athlons to Celerons/Core 2 Quads. What are the odds that every PC I have ever owned can't remain stable with a linux GUI? Not to mention that Adobe CSx Suite doesn't work on linux. Anyway, I am now looking at moving to a MAC in the hope of finding a stable GUI and a feature-packed command line. Does Mac OS have an integrated command line where I can do linux-like-awesomeness like rsync, ssh, wget, crong jobs, package updates, and git without having an unstable GUI? Basically, until the linux GUI applications get a little better, is OS X what I need?

  • How to prevent the command prompt from closing after execution?

    - by Sk8erPeter
    My problem is that in Windows, there are command line windows that close immediately after execution. To solve this, I want the default behavior to be that the window is kept open. Normally, this behavior can be avoided with three methods that come to my mind: Putting a pause line after batch programs to prompt the user to press a key before exiting Running these batch files or other command line manipulating tools (even service starting, restarting, etc. with net start xy or anything similar) within cmd.exe(Start - Run - cmd.exe) Running these programs with cmd /k like this: cmd /k myprogram.bat But there are some other cases in which the user: Runs the program the first time and doesn't know that the given program will run in Command Prompt (Windows Command Processor) e.g. when running a shortcut from Start menu (or from somewhere else), OR Finds it a little bit uncomfortable to run cmd.exe all the time and doesn't have the time/opportunity to rewrite the code of these commands everywhere to put a pause after them or avoid exiting explicitly. I've read an article about changing default behavior of cmd.exe when opening it explicitly, with creating an AutoRun entry and manipulating its content in these locations: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor\AutoRun HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor\AutoRun (The AutoRun items are _String values_...) I put cmd /d /k as a value of it to give it a try, but this didn't change the behaviour of the stuffs mentioned above at all... It just changed the behaviour of the command line window when opening it explicitly (Start-Run-cmd.exe). So how does it work? Can you give me any ideas to solve this problem?

  • How do you read a file line by line in your language of choice?

    - by Jon Ericson
    I got inspired to try out Haskell again based on a recent answer. My big block is that reading a file line by line (a task made simple in languages such as Perl) seems complicated in a functional language. How do you read a file line by line in your favorite language? So that we are comparing apples to other types of apples, please write a program that numbers the lines of the input file. So if your input is: Line the first. Next line. End of communication. The output would look like: 1 Line the first. 2 Next line. 3 End of communication. I will post my Haskell program as an example. Ken commented that this question does not specify how errors should be handled. I'm not overly concerned about it because: Most answers did the obvious thing and read from stdin and wrote to stdout. The nice thing is that it puts the onus on the user to redirect those streams the way they want. So if stdin is redirected from a non-existent file, the shell will take care of reporting the error, for instance. The question is more aimed at how a language does IO than how it handles exceptions. But if necessary error handling is missing in an answer, feel free to either edit the code to fix it or make a note in the comments.

  • When I try to run vim in command line I get Python errors

    - by Eduan
    When I try running vim in the Terminal (so as to follow @romainl's suggestion in my other question) I get lots of Python errors, which all boil down to: IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory) Why is this? I can use Python or Sublime Text even, without any problems. The full list of errors is the following: Traceback (most recent call last): File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 565, in <module> File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 547, in main File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 278, in addusersitepackages File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 253, in getusersitepackages File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 243, in getuserbase File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 523, in get_config_var File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 419, in get_config_vars File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 298, in _init_posix IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory) Extra info: I am on Mac OS X Mountain Lion (OS 10.8) EDIT: I tried @BobDunakey idea with no success, the idea was to use sudo. I still get the same errors. EDIT 2: I was able to solve the problem thanks to Zirak's solution, which is the following: http://clearfix.be/2012/08/05/fix-mountain-lion-10-8-python-ioerror-pyconfig-h-error/

  • Strings exported from a module have extra line breaks

    - by Jesse Millikan
    In a DrScheme project, I'm using a MrEd editor-canvas% with text% and inserting a string from a literal in a Scheme file. This results in an extra blank line in the editor for each line of text I'm trying to insert. I've tracked this down to the apparent fact that string literals from outside modules are getting extra line breaks. Here's a full example. The editor is irrelevant at this point, but it displays the result. ; test-literals.ss (module test-literals scheme (provide (all-defined-out)) (define exported-string "From another module with some more line breaks. ")) ; editor-test.ss (module editor-test scheme (require mred "test-literals.ss") (define w (instantiate frame% ("Editor Test" #f) )) (define c (instantiate editor-canvas% (w) (line-count 12) (min-width 400))) (define editor (instantiate text% ())) (send c set-editor editor) (send w show #t) (send editor erase) (send editor insert "Some text with some line breaks. ") (send editor insert exported-string)) And the result in the editor is Some text with some line breaks. From another module with some more line breaks.

  • Java - Reading a csv file line by line - stuck with weird non-existent characters being read!

    - by rockit
    hello fellow java developers. I'm having a very strange issue. I'm trying to read a csv file line by line. Im at the point where Im just testing out the reading of the lines. ONly each time that I read a line, the line contains square characters between each character of text. I even saved the file as a txt file in wordpad and notepad with no change. Thus I must be doing something stupid... I have a csv file, standard csv file, yes a text file with commas in it. I try to read a line of text, but the text is all f-ed up and cannot find the phrase within the text. Any advice? code below. //open csv File filReadMe = new File(strRoot + "data2.csv"); BufferedReader brReadMe = new BufferedReader(new InputStreamReader(new FileInputStream(filReadMe))); String strLine = brReadMe.readLine(); //for all lines while (strLine != null){ //if line contains "(see also" if (strLine.toLowerCase().contains("(see also")){ //write line from "(see also" to ")" int iBegin = strLine.toLowerCase().indexOf("(see also"); String strTemp = strLine.substring(iBegin); int iLittleEnd = strTemp.indexOf(")"); System.out.println(strLine.substring(iBegin, iBegin + iLittleEnd)); } //update line strLine = brReadMe.readLine(); } //end for brReadMe.close();

  • Microsoft Visio missing shape templates

    - by Rolnik
    I'm using MS Visio 2003 Standard. When I first was using it 3 years ago, it would let you search a database of thousands of ready-made templates, which I think Microsoft hosted at their own website. Several months ago, these templates were no longer available. I'm looking for some kind of replacement for common computer architecture and digital circuits, as well as user interface mock-ups. Does anybody know where I can find an assortment of these 'shapes'?

  • Software to draw 3D geometry

    - by ilovekonoka
    Does anyone know any software that can draw 3D geometry like figures usually seen in computer graphics papers and articles(example: http://www.iquilezles.org/www/articles/sphereao/sphereao.htm)? I know it can be done in Inskcape or Illustrator but I'm not sure they're the only choices.

  • How to pass a filename by drag-and-drop to a shortcut in Windows

    - by Kendall Frey
    I have a program program.exe and a document document.txt, and to open the document, I can drag document.txt onto program.exe. So far so good. Now I want to call it with a command-line parameter -param so that the full command line is program.exe -param document.txt Unfortunately, I can't do this with drag and drop, so I need to fire up cmd and type in the command manually. This takes too long, and I need an easier way. How can I create a shortcut that I can drop the file onto, and have it call the program with the command-line parameter? I tried setting the shortcut to program.exe -param "%1", but that didn't work, because it appeared to pass only the file name, and not the path, and since the current directory was the one with the program and not the one with the document, it couldn't find the document.

  • How to get pen input to draw?

    - by Cameron J
    I just got a crappy little Hyundai pen input module To use on a normal Windows 7 HP laptop, it works quite well with the Hyundai software, but that's in Chinese, and the input only stays on the screen for a second. When I try to use it in Paint, it just draws a dot, and switches back to an unclicked state, similarly, it's impossible to move a window. Is there ant way I can keep the click held down when the pen is touching the pad in order to draw, or is there any third party software anyone knows of that can do this?

  • organizing images by resolution with batch files

    - by Anthony
    Doing some digging I'm trying to figure out a command line solution for organizing very large archives of images based on their resolution into folders, 1920x1080, 1600x1200, 1600x900, etc. I've come across a few post on Superuser mentioning something called ImageMagick, is that the best method to the madness I'm trying to accomplish? I've never used any command line functions/applets/tools other then those that come from Microsoft. I'm rather new to command line usage but ive been enjoying the hell out of it using Powershell, xcopy and robocopy. I am slowly trying to push myself further into the Linux world with Ubuntu running on one of my physical machines as well as a virtual machine so that's an option as well.

  • How to parse pipe with multiple commands independently?

    - by yarun can
    How can I parse output of a single command by multiple commands without truncating at each step? For example ls -al|grep -i something will pass every line that has "something" in it to the next pipe which is fine, but that also means every other line in the pipe is discarded since there wont be matching the condition. What I want is to be able to operate on single pipe by many commands independently. In this case it a pipe from Mutt which passes the whole message body. I want to get grep, sed, delete and assign each of these to bash variables maybe. Initially what I want is to be able to assign "message id" to a variable, "subject" to another variable etc Then pass those into proper commands arguments. Here is how it will be MessageBodyFromMutt|grep something -Ax -Bx |grep another thing from the original message| sed some stuff from the original message| cut from here to there Obviously the above line does not do what I want. I want all these commands to operate on the original message body. I hope it makes sense

  • Drawing a WPF UserControl with DataBinding to an Image

    - by LorenVS
    Hey Everyone, So I'm trying to use a WPF User Control to generate a ton of images from a dataset where each item in the dataset would produce an image... I'm hoping I can set it up in such a way that I can use WPF databinding, and for each item in the dataset, create an instance of my user control, set the dependency property that corresponds to my data item, and then draw the user control to an image, but I'm having problems getting it all working (not sure whether databinding or drawing to the image is my problem) Sorry for the massive code dump, but I've been trying to get this working for a couple of hours now, and WPF just doesn't like me (have to learn at some point though...) My User Control looks like this: <UserControl x:Class="Bleargh.ImageTemplate" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:c="clr-namespace:Bleargh" x:Name="ImageTemplateContainer" Height="300" Width="300"> <Canvas> <TextBlock Canvas.Left="50" Canvas.Top="50" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.Customer,ElementName=ImageTemplateContainer}" /> <TextBlock Canvas.Left="50" Canvas.Top="100" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.Location,ElementName=ImageTemplateContainer}" /> <TextBlock Canvas.Left="50" Canvas.Top="150" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.ItemNumber,ElementName=ImageTemplateContainer}" /> <TextBlock Canvas.Left="50" Canvas.Top="200" Width="200" Height="25" FontSize="16" FontFamily="Calibri" Text="{Binding Path=Booking.Description,ElementName=ImageTemplateContainer}" /> </Canvas> </UserControl> And I've added a dependency property of type "Booking" to my user control that I'm hoping will be the source for the databound values: public partial class ImageTemplate : UserControl { public static readonly DependencyProperty BookingProperty = DependencyProperty.Register("Booking", typeof(Booking), typeof(ImageTemplate)); public Booking Booking { get { return (Booking)GetValue(BookingProperty); } set { SetValue(BookingProperty, value); } } public ImageTemplate() { InitializeComponent(); } } And I'm using the following code to render the control: List<Booking> bookings = Booking.GetSome(); for(int i = 0; i < bookings.Count; i++) { ImageTemplate template = new ImageTemplate(); template.Booking = bookings[i]; RenderTargetBitmap bitmap = new RenderTargetBitmap( (int)template.Width, (int)template.Height, 120.0, 120.0, PixelFormats.Pbgra32); bitmap.Render(template); BitmapEncoder encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(bitmap)); using (Stream s = File.OpenWrite(@"C:\Code\Bleargh\RawImages\" + i.ToString() + ".png")) { encoder.Save(s); } } EDIT: I should add that the process works without any errors whatsoever, but I end up with a directory full of plain-white images, not text or anything... And I have confirmed using the debugger that my Booking objects are being filled with the proper data... EDIT 2: Did something I should have done a long time ago, set a background on my canvas, but that didn't change the output image at all, so my problem is most definitely somehow to do with my drawing code (although there may be something wrong with my databinding too)

  • dynamically drawing polylines on googlemaps using php/mysql

    Hi. I am new to the googlemaps API. I have written a small app for my mobile phone that periodically updates its location to an SQL databse. I would like to display this information on a googlemap in my browser. Ideally i'd like to then poll the database periodically and if any new co-ords have arrived, add them to the line. Best way of describing it is this; http://tiny.cc/HEIa0 In a quest to get to there, i've started on the documents on google and been modifying them to try and acheive what I want.

So 100% is the color itself, 90% is a slightly lighter color, etc. Basically, it's like adding 10% of opacity to the color, if the color is on a white background. I need to convert the color into a hex HTML color value, so I don't want transparency. Is there an algorithm to get a tint of the System.Drawing.Color RGB value?
