parsing urls from windows batch file

- by modest

I have a text file (myurls.txt) whose contents are a list of URLs as follow: Slides_1: http://linux.koolsolutions.com/svn/ProjectA/tags/REL-1.0 Exercise_1: http://linux.koolsolutions.com/svn/ProjectA/tags/REL-1.0 Slides_2: http://linux.koolsolutions.com/svn/oldproject/ProjectB/tags/REL-2.0 Exercise_2: http://linux.koolsolutions.com/svn/ProjectB/tags/REL-1.0 Exercise_3: http://linux.koolsolutions.com/svn/BlueBook/ProjectA/tags/REL-1.0 Now I want to parse this text file in a for loop such that after each iteration (for e.g. take the first url from the above file) I have the following information into different variables: %i% = REL-1.0 %j% = http://linux.koolsolutions.com/svn/ProjectA %k% = http://linux.koolsolutions.com/svn/ProjectA/tags/REL-1.0 After some experiment I have the following code but it only works (kind of) if the URLs have same number of slashes: @echo off set FILE=myurls.txt FOR /F "tokens=2-9 delims=/ " %%i in (%FILE%) do ( @REM <do something with variables i, j and k.> ) I am fine with other solutions like for e.g. using Windows Script Host/VBS script as long as it can run with a default Windows XP/7 installation. In other words, I know I can use awk, grep, sed, python, etc. for Windows and get the job done but I don't want the users to have to install anything besides a standard windows installation.

Smart pagination algorithm

- by silvertab

I'm looking for an example algorithm of smart pagination. By smart, what I mean is that I only want to show, for example, 2 adjacent pages to the current page, so instead of ending up with a ridiculously long page list, I truncate it. Here's a quick example to make it clearer... this is what I have now: Pages: 1 2 3 4 [5] 6 7 8 9 10 11 This is what I want to end up with: Pages: ... 3 4 [5] 6 7 ... (In this example, I'm only showing 2 adjacent pages to the current page) I'm implementing it in PHP/Mysql, and the "basic" pagination (no trucating) is already coded, I'm just looking for an example to optimize it... It can be an example in any language, as long as it gives me an idea as to how to implement it...

PHP mail() function not delivering mail

- by Ryan Jones

Hi there, I have a slight problem. I am using a working script (works on my testing account - shared server) to send a mail through PHP using the mail() function. I just got a dedicated server, and I haven't been able to get the function to work. I've spent the last 10 or so hours reading various documentations on BIND (for the SPF record), dovecot, sendmail and postfix trying various things to get this to work. There is clearly something that I am missing. So we know the PHP code works fine. All the headers are fine everything. We know this as it's a direct copy from my testing account. So the problem must arise somewhere in the server config. The path to sendmail is correct, and sendmail is (apparently) working fine. I've set up the script to now deliver "Sent" or "Error" based on the boolean result from the PHP mail() function. That is: if(mail($blah,$blah,$blah,$blah,$blah)) { echo "Sent"; } else { echo "Error";} And the result ALWAYS comes up as "Sent" - however, the email never arrives. Can someone suggest things to check, as I'm completely new to this (24 hours or so!). Thanks in advance. Ryan

High level audio crossfading library for python

- by tcoopman

I am looking for a high level audio library that supports crossfading for python (and that works in linux). In fact crossfading a song and saving it is about the only thing I need. I tried pyechonest but I find it really slow. Working with multiple songs at the same time is hard on memory too (I tried to crossfade about 10 songs in one, but I got out of memory errors and my script was using 1.4Gb of memory). So now I'm looking for something else that works with python. I have no idea if there exists anything like that, if not, are there good command line tools for this, I could write a wrapper for the tool.

Search field using Ultraseek

- by tony noriega

So i realized today that using IE to do a search on my site, for instance the term "documents" returns the search results. if i use FireFox or Chrome the data in the input field is not recognized... now i looked at the code, and realized that there are no tags around the input fields... BUT if i put them, then IE does not work... what the heck do i do? <div class="searchbox" id="searchbox"> <script type="text/ecmascript"> function RunSearch() { window.location = "http://searcher.example.com:8765/query.html?ql=&col=web1&qt=" + document.getElementById("search").value; } </script> <div class="formSrchr"> <input type="text" size="20" name="qt" id="search" /> <input type="hidden" name="qlOld" id="qlOld" value="" /> <input type="hidden" name="colOld" id="colOld value="web1" /> <input type="image" name="imageField" src="/_images/search-mag.gif" width="20" height="20" onclick="RunSearch();" /> </div> </div>

PHP: Making my code simpler/shorter welcome message

- by Karem

Any suggestion to make this welcome message shorter: <?php if(isset($_SESSION['user_id'])) { if(isSet($_SESSION['1stTime'])){ ?> <strong id="welcome" style="font-size: 10px;"> <a href="logout.php"> Logga ut </a> </strong> <?php }else{ $_SESSION['1stTime'] = time(); ?> <script> $(document).ready(function() { $("#welcome").fadeIn("slow"); setTimeout(function(){ $("#welcome").fadeOut("slow"); setTimeout(function(){ $("#welcome").html("<a href='logout.php'>Logga ut</a>"); $("#welcome").fadeIn(); }, 800); }, 5000); }); </script> <strong id="welcome" style="display: none; color: #FFF; font-size: 10px;">Hej, <?php echo $FULL; ?>!</strong> <?php } } ?> First it checks if you are signed in. Next if 1stTime is set, if it is then show "Log out" in swedish, if it isnt, then introduce with "Hi, NAME", and then change to "Log out" after 5 seconds(jquery) + set the session How can i make this simpler?

Advanced example-driven C book with a lot of code.

- by Inso Reiges

Hello, I am looking for a book on advanced C programming that: Teaches how to effectively express one's solution in C when one already knows the language in depth. Shows some common design idioms expressed in C, like encapsulation, modularity and that kind of thing. Is example-driven with a lot of good-quality code. I already know the language itself so books like otherwise wonderful "Expert C Programming" by Peter van der Linden is not really what i am looking for. What i need is a book on how to express my design in C, what are the common idioms, best practices, etc. I would also like to note that i am primarily interested in C, not C++, C#, Objective-C or any other languages inspired by C-like syntax. Thank you.

non-blocking socket client connection

- by Igor

ALL, I am looking for a simple example of non-blocking socket connection that will run on Windows. I tried to Google, but all samples are either for *nix (POSIX) or blocking sockets on Windows. Looking thru msdn I see that it is easy to make a socket non-blocking and issue a connect(), but then you need some preparation in order to put the socket back. So, all in all I need something on a non-blocking socket that will connect and then put it back to be blocking. The read and write operation should be performed on the blocking socket. The reason for a non-blocking socket is that I need a connection timeout and there is no other way than non-blocking socket. Or is there? Thank you.

Reference book on Ruby on Rails social network site for novices

- by Christopher

Hey, so I am a novice programmer who has only worked with HTML, CSS, and a touch of Java a couple of years ago. I am looking to try to get a social network site up and running on Ruby on Rails and was looking at RailsSpace: Building a Social Networking Website with Ruby on Rails (Addison-Wesley Professional Ruby Series) - Paperback (July 30, 2007) by Michael Hartl. This was published in 2007, however, and the newer reviews say it is not very helpful. Does anyone know if there are any new publications out there that walk you through building a social network site while teaching you the code(rather than just using a out of the box program)? Thanks

Does Wicket hamper SEO or search engines ability to crawl?

- by Nick

We're coming from GWT projects and because of problems with SEO not liking GWT for our next project we're going to move clear of GWT (mainly because seo is a high priority for this next project). In choosing a new framework, I'm looking at Wicket and liking what I've seen so far. I've only done a few tutorials, but in looking at the war layout (from these tutorials) it looks like most of the html pages are in the WEB-INF folder. It this going to cause problems for SEO and search engines crawling through the sites files? Ideally, I'd like to use Wicket with some AJAX and deploy to Google App Engine.

When to use .NET Settings vs config <appsettings>?

- by jdk

Are there any recommendations on when to use Application settings (not per user settings) vs. .config file <appsettings>? Update Looking to understand some of the finer and important differences because they're both effectively key/value stores. For example, I know modifying appsettings in web.config will recycle the web application. Settings have been in .NET for a while now and I haven't bothered to look at them - maybe one is somewhat redundant, or using both at the same time doesn't make sense... that's the kind of detail I'm looking to understand and the reasons.

Is the method addSubview of NSView inherently slow? (Cocoa OSX)

- by Michael Minerva

I am trying to speed my gui that loads very slow slow when I am loading a large project (the gui is a representation of groups and sub groups and is made up of many views). During this process I was looking at how long certain code segments take to execute and I have found that a call to addsubview is taking between 10 and 20 milliseconds most of the time. The subview I was looking at is a disclosure button. I am wondering if this method is just inherently slow or is their some other factor at work here? Is the time it takes to add the subview dependent on the complexity of the subview or is that not a factor? Also, is there some other method that can be used to add a subview that might be faster?

loading a href's content into a shadowbox using .load() HELP!!!

- by kielie

<script type="text/javascript"> $(function() { $('#wp-calendar a').click(function(event) { event.preventDefault(); var url = $(this).attr('href') + ' #content'; var loaded = Shadowbox.load(url); Shadowbox.open({ content: loaded, player: "html", title: "<?php the_title(); ?>", height: 300, width: 470, }); }); }); </script> That is the code I am using to try and display content in a shadowbox, I am using the default wordpress calendar and with jQuery/AJAX (if I am not mistaken) adding this click event to every link in the calendar, so that when a link is clicked, the content is loaded and displayed in a shadowbox instead of opening on a new page. When I click on one of the links all I get inside of the shadowbox is "undefined". As I am sure you can see in my code, I am still very new to this, so any help or pointers would be appreciated. Thanx in advance!

Vehicle Make/Model and Parts Database

- by Jas Panesar

I am looking to see if there is a web based service I can either access programmatically to access teh following information, or a database I could purchase or interface with. I am looking to see if there are databases out there for: 1) Vehicle makes and models -- I recall something being out there in the $500/yr range 2) Vehicle Part Numbers - A database of car part numbers that is maintained and updated for a yearly subscription. I had read something similar about databases being purchased for other industries on SO.. so I figure this is fair game. Thanks in advance!

C++ library for Coordinate Transformation Matrices (CTM)?

- by BastiBense

I'm looking for a C++ library which allows for easy integration of Coordinate Transformation Matrices (CTM) in my application. You might know CTMs from PDF or PostScript. For one project we are using C++/Qt4 as a framework, which offers a QTransform class, which provides methods like .translate(double x, double y) or .rotate(double degrees). After doing some transformations, it would allow me to get all 6 CTM values, which I could feed into a PDF library or use a transformation matrix in export files. Qt's API also allows for arbitrary mapping of polygons (QPolygon), rectangles (QRect) and other primitive data structures into transformed coordinate systems. So basically I'm looking for something similar to what Qt provides, but without the need of using Qt. I know I could do the matrix multiplications myself, but I'm not really interested in doing so, as I'm very sure that someone already solved this problem, so please no links to books or other guides on how to multiply matrices. Thanks!

Upgrading PEAR in command prompt: "Error:Failed to mkdir C:\..."

- by noscript

I've just installed PEAR into WAMP attempting to follow this article. It all seems to have gone okay but when I type "pear upgrade" into the command prompt I get this error: ERROR: failed to mkdir c:\php\pear\docs\Archive_Tar\docs It is looking on the wrong drive (and missing a subdirectory in that path by the looks of it). It should be looking for D:\php\php5.3.13\pear\docs\Archive_Tar\docs When specifying installation directories I chose ones on the D:\ and thats where the folder structure is, the include_path in both php.ini locations have also been updated. I've also reset the WAMP server after making the changes. How do I set it to look / install the package in the right place?

Learning... anything really

- by WebDevHobo

I'm particularly interested in Windows PowerShell, but here's a somewhat more general complaint: When asking for help on learning something new, be it a small subject on PHP or understanding a class in Java, what usually happens is that people direct me towards the documentation pages. What I'm looking for is somewhat of a course. A deep explanation of why something works the way it does. I know my basic programming, like Java and C#. I've never seen C or C++, though I have seen a bit of assembler. I know what the Stack and Heap are, how boxing and unboxing works, why you have to deep-copy an array instead of copying the pointer and some other things. Windows PowerShell on the other hand, I know nothing about. And I notice that when reading the small document or some code, I usually forget what it does or why it works. What I am looking for is preferably, a nice tutorial that explains the beginnings, the concepts, and goes to more difficult things at a steady pace. The only thing documentation can do is explain what a function does. That's no good to me since I don't know what I want to do yet. I could read about a thousand functions, and forget about most of them, because I don't need to implement them right after it. Randomly wandering through the documentation doesn't do me any good. So conclude, what is a good tutorial on Windows Powershell? One which explains in clear language what is happening, one which builds on previous things learned. I don't think googling this is a good idea. Doing a Google search on this would turn up numerous tutorials. And experience tells me that you have to look long and hard to find the gem you're looking for. That's why I'm asking here. Because this is the place where you can find more experienced people. Many of the PowerShell guys among you will know the good ones already, and by asking you, I avoid wasting time that could be spent learning. So to summarize: I will not google this!

How can I define an empty array in a Perl construtor?

- by Laimoncijus

I am just beginner with Perl, so if it sounds stupid - sorry for that :) My problem is - I am trying to write a class, which has an empty array, defined in constructor of a class. So I am doing this like this: package MyClass; use strict; sub new { my ($C) = @_; my $self = { items => () }; bless $self, ref $C || $C; } sub get { return $_[0]->{items}; } 1; Later I am testing my class with simple script: use strict; use Data::Dumper; use MyClass; my $o = MyClass->new(); my @items = $o->get(); print "length = ", scalar(@items), "\n", Dumper(@items); And while running the script I get following: $ perl my_test.pl length = 1 $VAR1 = undef; Why am I doing wrong what causes that I get my items array filled with undef? Maybe someone could show me example how the class would need to be defined so I would not get any default values in my array?

How to write automated tests for SQL queries?

- by James

The current system we are adopting at work is to write some extremely complex queries which perform multiple calculations and have multiple joins / sub-queries. I don't think I am experienced enough to say if this is correct or not so I am agreeing and attempting to function with this system as it has clear benefits. The problem we are having at the moment is that the person writing the queries makes a lot of mistakes and assumes everything is correct. We have now assigned a tester to analyse all of the queries but this still proves extremely time consuming and stressful. I would like to know how we could create an automated procedure (without specifically writing it with code if possible as I can work out how to do that the long way) to verify a set of 10+ different inputs, verify the output data and say if the calculations are correct. I know I could write a script using specific data in the database and create a script using c# (the db is SQL Server) and verify all the values coming out but I would like to know what the official "standard" is as my experience is lacking in this area and I would like to improve. I am happy to add more information if required, add a comment if necessary. Thank you. Edit: I am using c#

JavaScript: Very strange behavior with assigning methods in a loop

- by Andrey

Consider this code below: <a href="javascript:void(-1)" id="a1">a1</a> <a href="javascript:void(-1)" id="a2">a2</a> <script type="text/javascript"> var buttons = [] buttons.push("a1") buttons.push("a2") var actions = [] for (var i in buttons) { actions[buttons[i]] = function() { alert(i) } } var elements = document.getElementsByTagName("a") for (var k = 0; k < elements.length; k++) { elements[k].onclick = actions[elements[k].id] } </script> Basically, it shows two anchors, a1 and a2, and I expect to see "1" and "2" popping up in an alert when clicking on corresponding anchor. It doesn't happen, I get "2" when clicking on either. After spending an hour meditating on the code, I decided that it probably happens because dynamic onclick methods for both anchors keep the last value of "i". So I change that loop to for (var i in buttons) { var local_i = i.toString() actions[buttons[i]] = function() { alert(local_i) } } hoping that each dynamic function will get its own copy of "i" with immediate value. But after this change I get "1" popping up when I click on either link. What am I doing wrong? It's a huge show stopper for me.

How to test jQuery Ajax with php?

- by vladv

I tried to just send some information to a php file using Jquery Ajax. I wanted to send some info to the php file every time a click is made. <script> $(document).ready(function() { $('#checkbox').click(function() { $.ajax({type : "POST", url : "test.php", data : "ffs=somedata&ffs2=somedata2", succes : function() { alert("something"); } }); }); }); </script> <body> <input type = "checkbox" name = "checkbox" id = "checkbox"> </body> The php file looks like this: <?php echo $_POST['ffs']; ?> Now, I see the POST going, (using firebug). I get no errors, but nothing happens in the php file. Also success is never reached, so no alert is triggered. What should I do in the php file so that I can trigger success and also see the sent info?
