  • Need help parsing file/writing script

    - by Bradley Herman
    Hey all, I have been doing nothing but web development over the last few years and haven't written any Java or C++ in what feels like forever. I don't necessarily need to use these languages, so I'm entirely open to suggestion. I was given an email list by a client to import into their mailchimp account yesterday and unfortunately, Mailchimp couldn't read the file. It's a text file, but I don't believe it's tab delimited (which would make this much, much easier for me). A small portion of the file (I've changed last names and email addresses) can be viewed here: http://sparktoignite.com/patients.txt If anyone has suggestions on how I can get this into a Mailchimp readable format (csv, tab delimited txt, excel) please let me know. I feel like 3 years ago I would've been able to do this in a matter of minutes, but given that I haven't touched anything other than RoR, PHP, and jQuery for the last few years, I don't know where to start. Thanks!

  • Run shell script using fabric and piping script text to shell's stdin

    - by Peter Lyons
    Is there a way to execute a multi-line shell script by piping it to the remote shell's standard input in fabric? Or must I always write it to the remote filesystem, then run it, then delete it? I like sending to stdin as it avoids the temporary file. If there's no fabric API (and it seems like there is not based on my research), presumably I can just use the ssh module directly. Basically I wish fabric.api.run was not limited to a 1-line command that gets passed to the shell as a command line argument, but instead would take a full multi-line script and write it to the remote shell's standard input.

  • MySQL script to delete data in chunks until everything lower then id has been deleted

    - by Chriswede
    I need an MySQL Skript which does the following: delete chunks of the database until it has deleted all link_id's greater then 10000 exmaple: x = 10000 DELETE FROM pligg_links WHERE link_id > x and link_id < x+10000 x = x + 10000 ... So it would delete DELETE FROM pligg_links WHERE link_id > 10000 and link_id < 20000 then DELETE FROM pligg_links WHERE link_id > 20000 and link_id < 30000 until all id's less then 10000 have been removed I need this because the database is very very big (more then a gig) thank in advance

  • Looking for a 'pick a-or-b' voting system script

    - by user324455
    Apologies: this is my first time on stackoverflow and I'm starting with a question and seeking advice. Sorry. Caveats: I know HTML and CSS pretty well. Javascript and PHP are not completely alien, but I'm really pretty basic on those. That said, I'm pretty sharp and willing to search for explanations independently. Ok, so my question is this: I want to create a site with a voting system very much like the one on kittenwar.com - the page loads 2 random images from a db of some sort and you click on the one you want to 'win'. Ranked pairs kind of deal. Then there is a leaderboard of those images which have the highest win-loss ratio. There also needs to be an uploader for peeps to upload their own images and have them go into an approval workflow, and from there into the db that feeds the voting thing. I tried a pre-made solution ('photo battle') but found it was completely standalone, so trying to integrate it or change any of the options was a nightmare, plus it was buggy. i'm sure there has to be a relatively easy way to do this, right? Ideally I'd like to build my site in Joomla and integrate this functionality somehow. I'd be very grateful for any advice on this. Thanks Tom

  • RegEx (or other) parsing of script

    - by jpmyob
    RegEx is powerful - it is tru but I have a little - query for you I want to parse out the FUNCTIONS from some old code in JS...however - I am RegEx handicapped (mentally deficient in grasping the subtleties).. the issue that makes me NOT EVEN TRY - is two fold - 1) myVar = function(x){ yadda yadda } AND function myVar(x) { yadda yadda } are found throuout - COLD I write a parser for each? sure - but that seems inefficient... 2) MANY things may reside INSIDE the {} including OTHER sets of {} or other Functions(){} block of text... HELP - does anyone have, or know of some code parsing snippets or examples that will parse out the info I want to collect? Thanks

  • specify parent window in Windows Resource Script file(*.rc)

    - by welemon
    Hi, I'm looking for a method to specify parent window in *.rc file. In *.rc file, it contains the layout and controls of a dialog. Any new control added into it, will automatically become a child window of Dialog itself. But I want to add a custom draw window into dialog, and some other controls which has that "custom draw window" as parent window, not dialog itself. I know I can use ::CreateWindow(...) API to dynamic create a window in code, and specify the custom draw window as parent HWND. But we already has child controls layout in *.rc file, I just want to reuse them, without create HWND again. Thanks, William L.

  • Sort ranges in an array in google apps script

    - by user1637113
    I have a timesheet spreadsheet for our company and I need to sort the employees by each timesheet block (15 rows by 20 columns). I have the following code which I had help with, but the array quits sorting once it comes to a block without an employee name (I would like these to be shuffled to the bottom). Another complication I am having is there are numerous formulas in these cells and when I run it as is, it removes them. I would like to keep these intact if at all possible. Here's the code: function sortSections() { var activeSheet = SpreadsheetApp.getActiveSheet(); //SETTINGS var sheetName = activeSheet.getSheetName(); //name of sheet to be sorted var headerRows = 53; //number of header rows var pageHeaderRows = 5; //page totals to top of next emp section var sortColumn = 11; //index of column to be sorted by; 1 = column A var pageSize = 65; var sectionSize = 15; //number of rows in each section var col = sortColumn-1; var sheet = SpreadsheetApp.getActive().getSheetByName(sheetName); var data = sheet.getRange(headerRows+1, 1, sheet.getMaxRows()-headerRows, sheet.getLastColumn()).getValues(); var data3d = []; var dataLength = data.length/sectionSize; for (var i = 0; i < dataLength; i++) { data3d[i] = data.splice(0, sectionSize); } data3d.sort(function(a,b){return(((a[0][col]<b[0][col])&&a[0][col])?-1:((a[0][col]>b[0][col])?1:0))}); var sortedData = []; for (var k in data3d) { for (var l in data3d[k]) { sortedData.push(data3d[k][l]); } } sheet.getRange(headerRows+1, 1, sortedData.length, sortedData[0].length).setValues(sortedData);

  • Shell script exiting the loop after calling another script

    - by Johnyy
    Hi Guys, I have a shell script s1 calling another script s2 in a loop. However s1 can not seem to continue the loop after s2 returns. Commenting out the line that calls s2 will enable the loop to continue. s2 does copy of one file, s1 checks conditions and copy several files using s2. Can anyone give a pointer what is going on here? ... while read line s2 param1 param2 param3 echo "copy done" done < $tempfile echo "out of loop" ... "copy done" is printed, so is "out of loop"

  • Tasks API using Google Apps Script (complete task)

    - by Cartman
    I am trying to set the status of a task as completed using Tasks API. It shows that the code has completed successfully, but the task is not being marked as completed. Also, when I try to get the status of the task after update, it shows status as "needsAction". Here is my code function setTaskStatus(){ // Suppose a task with name "MyTaskListName" is contained //within task list with name "MyTaskName" var tasklist = Tasks.Tasklists.list().getItems(); var title = 'MyTaskListName'; var id; for(var i in tasklist){ if(title == tasklist[i].getTitle()){ id = tasklist[i].getId(); } } //Get the task list items var tasks = Tasks.Tasks.list(id).getItems(); for(var i in tasks){ if(tasks[i].getTitle() == 'MyTaskName'){ tasks[i].setStatus("completed");// set status completed Logger.log(tasks[i].getStatus());// this shows that the task has completed //But it does not reflect actually } } }

  • How employable am I as a programmer?

    - by dsimcha
    I'm currently a Ph.D. student in Biomedical Engineering with a concentration in computational biology and am starting to think about what I want to do after graduate school. I feel like I've accumulated a lot of programming skills while in grad school, but taken a very non-traditional path to learning all this stuff. I'm wondering whether I would have an easy time getting hired as a programmer and could fall back on that if I can't find a good job directly in my field, and if so whether I would qualify for a more prestigious position than "code monkey". Things I Have Going For Me Approximately 4 years of experience programming as part of my research. I believe I have a solid enough grasp of the fundamentals that I could pick up new languages and technologies pretty fast, and could demonstrate this in an interview. Good math and statistics skills. An extensive portfolio of open source work (and the knowledge that working on these projects implies): I wrote a statistics library in D, mostly from scratch. I wrote a parallelism library (parallel map, reduce, foreach, task parallelism, pipelining, etc.) that is currently in review for adoption by the D standard library. I wrote a 2D plotting library for D against the GTK Cairo backend. I currently use it for most of the figures I make for my research. I've contributed several major performance optimizations to the D garbage collector. (Most of these were low-hanging fruit, but it still shows my knowledge of low-level issues like memory management, pointers and bit twiddling.) I've contributed lots of miscellaneous bug fixes to the D standard library and could show the change logs to prove it. (This demonstrates my ability read other people's code.) Things I Have Going Against Me Most of my programming experience is in D and Python. I have very little to virtually no experience in the more established, "enterprise-y" languages like Java, C# and C++, though I have learned a decent amount about these languages from small, one-off projects and discussions about language design in the D community. In general I have absolutely no knowledge of "enterprise-y" technlogies. I've never used a framework before, possibly because most reusable code for scientific work and for D tends to call itself a "library" instead. I have virtually no formal computer science/software engineering training. Almost all of my knowledge comes from talking to programming geek friends, reading blogs, forums, StackOverflow, etc. I have zero professional experience with the official title of "developer", "software engineer", or something similar.

  • I don't know C. And why should I learn it?

    - by Stephen
    My first programming language was PHP (gasp). After that I started working with JavaScript. I've recently done work in C#. I've never once looked at low or mid level languages like C. The general consensus in the programming-community-at-large is that "a programmer who hasn't learned something like C, frankly, just can't handle programming concepts like pointers, data types, passing values by reference, etc." I do not agree. I argue that: Because high level languages are easily accessible, more "non-programmers" dive in and make a mess, and In order to really get anything done in a high level language, one needs to understand the same similar concepts that most proponents of "learn-low-level-first" evangelize about. Some people need to know C. Those people have jobs that require them to write low to mid-level code. I'm sure C is awesome. I'm sure there are a few bad programmers who know C. My question is, why the bias? As a good, honest, hungry programmer, if I had to learn C (for some unforeseen reason), I would learn C. Considering the multitude of languages out there, shouldn't good programmers focus on learning what advances us? Shouldn't we learn what interests us? Should we not utilize our finite time moving forward? Why do some programmers disagree with this? I believe that striving for excellence in what you do is the fundamental deterministic trait between good programmers and bad ones. Does anyone have any real world examples of how something written in a high level language--say Java, Pascal, PHP, or Javascript--truely benefitted from a prior knowledge of C? Examples would be most appreciated. (revised to better coincide with the six guidelines.)

  • F# for the C# Programmer

    - by mbcrump
    Are you a C# Programmer and can’t make it past a day without seeing or hearing someone mention F#?  Today, I’m going to walk you through your first F# application and give you a brief introduction to the language. Sit back this will only take about 20 minutes. Introduction Microsoft's F# programming language is a functional language for the .NET framework that was originally developed at Microsoft Research Cambridge by Don Syme. In October 2007, the senior vice president of the developer division at Microsoft announced that F# was being officially productized to become a fully supported .NET language and professional developers were hired to create a team of around ten people to build the product version. In September 2008, Microsoft released the first Community Technology Preview (CTP), an official beta release, of the F# distribution . In December 2008, Microsoft announced that the success of this CTP had encouraged them to escalate F# and it is now will now be shipped as one of the core languages in Visual Studio 2010 , alongside C++, C# 4.0 and VB. The F# programming language incorporates many state-of-the-art features from programming language research and ossifies them in an industrial strength implementation that promises to revolutionize interactive, parallel and concurrent programming. Advantages of F# F# is the world's first language to combine all of the following features: Type inference: types are inferred by the compiler and generic definitions are created automatically. Algebraic data types: a succinct way to represent trees. Pattern matching: a comprehensible and efficient way to dissect data structures. Active patterns: pattern matching over foreign data structures. Interactive sessions: as easy to use as Python and Mathematica. High performance JIT compilation to native code: as fast as C#. Rich data structures: lists and arrays built into the language with syntactic support. Functional programming: first-class functions and tail calls. Expressive static type system: finds bugs during compilation and provides machine-verified documentation. Sequence expressions: interrogate huge data sets efficiently. Asynchronous workflows: syntactic support for monadic style concurrent programming with cancellations. Industrial-strength IDE support: multithreaded debugging, and graphical throwback of inferred types and documentation. Commerce friendly design and a viable commercial market. Lets try a short program in C# then F# to understand the differences. Using C#: Create a variable and output the value to the console window: Sample Program. using System;   namespace ConsoleApplication9 {     class Program     {         static void Main(string[] args)         {             var a = 2;             Console.WriteLine(a);             Console.ReadLine();         }     } } A breeze right? 14 Lines of code. We could have condensed it a bit by removing the “using” statment and tossing the namespace. But this is the typical C# program. Using F#: Create a variable and output the value to the console window: To start, open Visual Studio 2010 or Visual Studio 2008. Note: If using VS2008, then please download the SDK first before getting started. If you are using VS2010 then you are already setup and ready to go. So, click File-> New Project –> Other Languages –> Visual F# –> Windows –> F# Application. You will get the screen below. Go ahead and enter a name and click OK. Now, you will notice that the Solution Explorer contains the following: Double click the Program.fs and enter the following information. Hit F5 and it should run successfully. Sample Program. open System let a = 2        Console.WriteLine a As Shown below: Hmm, what? F# did the same thing in 3 lines of code. Show me the interactive evaluation that I keep hearing about. The F# development environment for Visual Studio 2010 provides two different modes of execution for F# code: Batch compilation to a .NET executable or DLL. (This was accomplished above). Interactive evaluation. (Demo is below) The interactive session provides a > prompt, requires a double semicolon ;; identifier at the end of a code snippet to force evaluation, and returns the names (if any) and types of resulting definitions and values. To access the F# prompt, in VS2010 Goto View –> Other Window then F# Interactive. Once you have the interactive window type in the following expression: 2+3;; as shown in the screenshot below: I hope this guide helps you get started with the language, please check out the following books for further information. F# Books for further reading   Foundations of F# Author: Robert Pickering An introduction to functional programming with F#. Including many samples, this book walks through the features of the F# language and libraries, and covers many of the .NET Framework features which can be leveraged with F#.       Functional Programming for the Real World: With Examples in F# and C# Authors: Tomas Petricek and Jon Skeet An introduction to functional programming for existing C# developers written by Tomas Petricek and Jon Skeet. This book explains the core principles using both C# and F#, shows how to use functional ideas when designing .NET applications and presents practical examples such as design of domain specific language, development of multi-core applications and programming of reactive applications.

  • Run a startup script with lightdm

    - by cheshirekow
    I have a tablet PC and the graphics driver doesn't support xrandr, so in order to rotate the screen I run a script which changes the Xorg.conf file and then restarts lightdm. I also have a script which uses xsetwacom and xinput to change the rotation of the input devices so that the match the new orientation. I've learned how to get the script to run when I login, but I'd like it to run before I login, so that I don't have to enable auto-login with lightdm. I do need it to run though, or the input (touch and pen) is rotated with respect to the screen, so that when I touch the screen the input is in a completely different area, making it really difficult to use the onscreen keyboard. I've looked at other questions on this site. I've tried putting my script in /etc/Xsession.d but that didn't seem to work. I also tried putting it in /etc/rc.local but I think that is the wrong place, nothing seems to happen. I've also tried googling for lightm script hooks, and various other google terms. Any suggestions? Edit 1: After doing some research, it seems to me that it might not be that I want to run a script with lightdm, but rather with the lighdm greeter (in this case, I think the unity-greeter?). Are there any script-hooks for the unity-greeter?

  • Are you a good or bad programmer?

    - by Eli
    Hi All, I see a lot of questions on SO that are asked about 'good' programmers vs 'bad' programmers. For example, what is a good/bad programmer, how to tell a good/bad programmer, what to do about a bad programmer on a team, how to hire a good programmer. I know it's pretty easy to apply the words to other people, but I find myself wondering if anyone out there would actually define THEMSELVES in a Boolean fashion like this, rather than "good in some areas, weak in others..." I'm not asking as an either/or where you have to be one or the other, but as a 'both' - are you a good or bad programmer? If so (either one), why? Please note this isn't meant to be argumentative, or to define good/bad practices, etc. I just want to know how many people think they are good, bad, or neither out there.

  • Chrome "refusing to execute script"

    - by TestSubject528491
    In the head of my HTML page, I have: <script src="https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js"></script> When I load the page in my browser (Google Chrome v 27.0.1453.116) and enable the developer tools, it says Refused to execute script from 'https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled. Indeed, the script won't run. Why does Chrome think this is a plaintext file? It clearly has a js file extension. Since I'm using HTML5, I omitted the type attribute, so I thought that might be causing the problem. So I added type="text/javascript" to the <script> tag, and got the same result. I even tried type="application/javascript" and still, same error. Then I tried changing it to type="text/plain" just out of curiosity. The browser did not return an error, but of course the JavaScript did not run. Finally I thought the periods in the filename might be throwing the browser off. So in my HTML, I changed all the periods to the URL escape character %2E: <script src="https://raw.github.com/cloudhead/less%2Ejs/master/dist/less-1%2E3%2E3.js"></script> This still did not work. The only thing that truly works (i.e. the browser does not give an error and the JS successfully runs) is if I download the file, upload it to a local directory, and then change the src value to the local file. I'd rather not do this since I'm trying to save space on my own website. How do I get the Chrome to recognize that the linked file is actually a javascript type?

  • How do I configure upstart to run a script on shutdown when the process takes longer than 10secs?

    - by Tiris
    I am running ubuntu 11.10 in a virtual machine (VirtualBox) to learn more about development in linux. I am using a git repository to save my work and have written a script to bundle my work up and save it to the shared folder for use while the virtual machine is not running. I would like to automatically run this script before shutdown so that my work is always available if the vm is off (currently I have to manually run the script). I don't know if upstart is the best way to accomplish this, but this is the config that I wrote as a test: description "test script to run at shutdown" start on runlevel [056] task script touch /media/sf_LinuxEducation/start sleep 15 touch /media/sf_LinuxEducation/start-long end script pre-start script touch /media/sf_LinuxEducation/pre-start sleep 15 touch /media/sf_LinuxEducation/pre-start-long end script post-start script touch /media/sf_LinuxEducation/post-start sleep 15 touch /media/sf_LinuxEducation/post-start-long end script pre-stop script touch /media/sf_LinuxEducation/pre-stop sleep 15 touch /media/sf_LinuxEducation/pre-stop-long end script post-stop script touch /media/sf_LinuxEducation/post-stop sleep 15 touch /media/sf_LinuxEducation/post-stop-long end script The result is that only one touch is accomplished (the first touch in pre-start). What do I need to change to see one of the touches after the sleep to work? Or Is there an easier way to get this accomplished? Thanks in advance.

  • Override variables while testing a standalone Perl script

    - by BrianH
    There is a Perl script in our environment that I now need to maintain. It is full of bad practices, including using (and re-using) global variables throughout the script. Before I start making changes to the script, I was going to try to write some test scripts so I can have a good regression base. To do this, I was going to use a method described on this page. I was starting by writing tests for a single subroutine. I put this line somewhat near the top of the script I am testing: return 1 if ( caller() ); That way, in my test script, I can require 'script_to_test.pl'; and it won't execute the whole script. The first subroutine I was going to test makes a lot of use of global variables that are set throughout the script. My thought was to try to override these variables in my test script, something like this: require_ok('script_to_test.pl'); $var_from_other_script = 'Override Value'; ok( sub_from_other_script() ); Unfortunately (for me), the script I am testing has a massive "my" block at the top, where it declares all variables used in the script. This prevents my test script from seeing/changing the variables in the script I'm running tests against. I've played with Exporter, Test::Mock..., and some other modules, but it looks like if I want to be able to change any variables I am going to have to modify the other script in some fashion. My goal is to not change the other script, but to get some good tests running so when I do start changing the other script, I can make sure I didn't break anything. The script is about 10,000 lines (3,000 of them in the main block), so I'm afraid that if I start changing things, I will affect other parts of the code, so having a good test suite would help. Is this possible? Can a calling script modify variables in another script declared with "my"? And please don't jump in with answers like, "Just re-write the script from scratch", etc. That may be the best solution, but it doesn't answer my question, and we don't have the time/resources for a re-write.
