• Perl Regular expression remove double tabs, line breaks, white spaces

  - by Scoox

  Hi guys, I want to write a perl script that removes double tabs, line breaks and white spaces. What I have so far is: $txt=~s/\r//gs; $txt=~s/ +/ /gs; $txt=~s/\t+/\t/gs; $txt=~s/[\t\n]*\n/\n/gs; $txt=~s/\n+/\n/gs; But, 1. It's not beautiful. Should be possible to do that with far less regexps. 2. It just doesn't work and I really do not know why. It leaves some double tabs, white spaces and empty lines (i.e. lines with only a tab or whitespace) I could solve it with a while, but that is very slow and ugly. Any suggestions?

• Any active Bold for Delphi users ?

  - by Roland Bengtsson

  What are you using as a persistance framework when programming in Delphi? If the application is growing it soon became really complicated to handle the model in SQL ? Bold is a persistance framework for Delphi win32 that really deserve more attention. I use it daily and using OCL instead of SQL to get data from the database saves a lot of time and debugging. When the model is changed Bold translate this to an SQL script and change the database. EDIT: For those that are interested in Bold for Delphi I have spend this evening on create a site on Google about it. I'm not a guru in html so the design is maybe not so exciting. But I want comments and reactions about the site. You can leave the comments in this thread or at the bottom on the subpage. And the address is... http://sites.google.com/site/boldfordelphi/

• Can't detect MIME type when using Zend Zend_File_Transfer_Adapter_Http !

  - by mrblue

  Hi all, I am writing a small script to upload and detect MIME type, using Zend Framework. For the design purpose, I can't use Zend_Form but normal instead. And I simply apply from the manual : $adapter = new Zend_File_Transfer_Adapter_Http(); $files = $adapter-getFileInfo(); $mime = $files-getMimeType(); But the system inform that the funcion getMimeType() does not existed. Then, I tried: $adapter = new Zend_File_Transfer(); $files = $adapter-getFileInfo(); $mime = $files-getMimeType(); This time, it didn't work either. So, how can I get the MIME type ? Thank you so much for your help

• PHP MySQL New Lines / Whitespaces from textarea

  - by rob_robsen

  I've a problem about whitespaces and new lines at the beginning of a textarea. I send a json string with ajax to the php script. Then I decode the string into an php array (with json_decode). So I have a string in this array with two line breaks at the beginning. If a print the text from the array, the line breaks are there, but if I store the text into the mysql database, the line breaks are gone... Only at the beginning of the string, the line breaks gone... At the rest of the string, the line breaks are ok. Thanks for your answers! rob

• flash.media.Sound.play takes long time to return

  - by Fire Lancer

  I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

• ModalPopupExtender doesn't work on IE6 frame layout

  - by Joe

  I'm using a "frame" layout similar to the one in this excellent answer: a div #top at the top of the page, a div#left on the left, and a div #main with the main content. The #top and #left divs contain navigation menus. Now I want to use a popup div using the AjaxControlToolkit ModalPopupExtender inside the content (#main) div. This works fine on IE8 (where #top, #left, #main all have position:fixed), but when I run it on IE6, the modal background only covers the #main div - I need it to cover the whole of the page including the #top and #left navigation divs. Looking at the script for ModalPopupExtender, it appears to be searching up the parent hierarchy until it finds a parent with position relative or absolute. And in the IE6 rendering, the #main div has position:absolute because position:fixed is not supported, which I guess explains what is happening. Any suggestions for the best/easiest way to get this working properly on IE6? Ideally without modifying the ModalPopupExtender code, but I'll do this if I have to and it's the best solution.

• Getting a permission error when trying to connect to sql database

  - by Matt

  I have a sql server on a dedicated machine, running SQL 2008. I have the IP of the box, a database setup on it. I've built a small script that just does a connection test, and when I run it, I get the following error. Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I've been told by the admin that SQL remote access has been granted for my IP address. Anybody know what's wrong?

• Display constantly updating information in-place in command-line window using python?

  - by AndyL

  I am essentially building a timer. I have a python script that monitors for an event and then prints out the seconds that have elapsed since that event. Instead of an ugly stream of numbers printed to the command line, I would like to display only the current elapsed time "in-place"-- so that only one number is visible at any given time. Is there a simple way to do this? If possible I'd like to use built-in python modules. I'm on Windows, so simpler the better. (E.g. no X11).

• receive xml file via post in php

  - by thegunner

  Hi, I'm looking for a PHP script that can accept an XML file via a POST, then send a response.... Does anyone have any code that could do this? So far the only code I have is this but not sure about the response or if indeed I am even going in the right direction as XML characters are not saved correctly. Any ideas? <?php if ( $_SERVER['REQUEST_METHOD'] === 'POST' ){ $postText = file_get_contents('php://input'); } $datetime=date('ymdHis'); $xmlfile = "myfile" . $datetime . ".xml"; $FileHandle = fopen($xmlfile, 'w') or die("can't open file"); fwrite($FileHandle, $postText); fclose($FileHandle); ?> Thanks,

• How to assign a PHP variable that contains a mixed of PHP and html elements?

  - by Rick

  I have a PHP page that contains html and tags and PHP codes and I am using AJAX to manipulate some data and now I need to spit out the response but I am not sure if it is possible to put the mixed content into a string variable to pass through... Is this possible? For example I need to: $response = "<p>some text--<?php echo $something; ?>"; Thanks... To clear things up, I am not trying to send raw PHP code to clientside as that would be silly and won't be evaluated as it is a server side script. I am just looking for a fast way to put everything into a variable without manually re-doing the whole page stripping out the php open and close tags and echos...etc

• SQL Compare-Like tool for Oracle?

  - by Hitchhiker

  We're a .NET team which uses the Oracle DB for a lot of reasons that I won't get into. But deployment has been a bitch. We are manually keeping track of all the changes to the schema in each version, by keeping a record of all the scripts that we run during development. Now, if a developer forgets to check-in his script to the source control after he ran it - which is not that rare - at the end of the iteration we get a great big headache. I hear that SQL Compare by Red-Gate might solve these kind of issues, but it only has SQL Server support. Anybody knows of a similar tool for Oracle? I've been unable to find one.

• Organization of linking to external libraries in C++

  - by Nicholas Palko

  In a cross-platform (Windows, FreeBSD) C++ project I'm working on, I am making use of two external libraries, Protocol Buffers and ZeroMQ. In both projects, I am tracking the latest development branch, so these libraries are recompiled / replaced often. For a development scenario, where is the best place to keep libprotobuf.{a,lib} and zeromq.{so,dll}? Should I have my build script copy them from their respective project directories into my local project's directory (say MyProjectRoot/lib or MyProjectRoot/bin) before I build my project? This seems preferable to tossing things into /usr/local/lib, as I wouldn't want to replace a system-wide stable version with the latest experimental one. Cmake warns me whenever I specify a relative path for linking, so I would suspect copying is a better solution then relative linking? Is this the best approach? Thanks for your help!

• Mac OS X Services: enable without user interaction?

  - by kclement

  I wrote a simple Mac 'Service' for Finder, that executes a command. Basically: this adds a ContextMenu in Finder. If I right-click a file in Finder, a menu item pops up. If the user clicks it, it executes my script. (kind of like 'Send to Bluetooth device, ...') In OS X Leopard (10.5) and earlier, all services are enabled. In 10.6 (Snow Leopard), Apple changed the behavior, services now have preferences, and can be enabled or disabled by the user. (which is a good thing) However, I wrote the service, but there seems to be no way to enable it automatically (in our installer). I tried doing it with Applescript, going to the System Preferences and ticking the checkbox that way, but it requires some accessibility features to be turned on. (off by default). Is it possible? If so, how? Or do I need something else to provide Context Menus in Finder.

• Depmod - unresolved symbols in rt73 module

  - by Xolstice

  I'm trying to install a linux driver for my wireless network card (D-Link DWL-G510) on my Red Hat Linux 7.1 machine with a 2.4.37.9 kernel. I downloaded the serial monkey driver from the sourceforge site and was able to successfully compile the module. However, whenever I do a "make install", the make script executes a "depmod -a" command which then complains with the message: "Unresolved symbols in /lib/modules/2.4.37.9/extra/rt73.o". I then executed a "depmod -e" command to show unresolved symbols and it indicates the following information: request_firmware_Rsmp_38ce5074 release_firmware_Rsmp_33934162 I did a grep on the above information and it showed no source files making reference to it. I searched for it on google and it returned no results. Can anyone help?

• mysql does not utilize my cpu and ram enough?

  - by vick

  Hello Everyone! I am importing a 2.5gb csv file to a mysql table. My storage engine is innodb. Here is the script: use xxx; DROP TABLE IF EXISTS `xxx`.`xxx`; CREATE TABLE `xxx`.`xxx` ( `xxx_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(128) NOT NULL, `yy` varchar(128) NOT NULL, `yyy` varchar(64) NOT NULL, `yyyy` varchar(2) NOT NULL, `yyyyy` varchar(10) NOT NULL, `url` varchar(64) NOT NULL, `p` varchar(10) NOT NULL, `pp` varchar(10) NOT NULL, `category` varchar(256) NOT NULL, `flag` varchar(4) NOT NULL, PRIMARY KEY (`xxx_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; set autocommit = 0; load data local infile '/home/xxx/raw.csv' into table company fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n' ( name, yy, yyy, yyyy, yyyyy, url, p, pp, category, flag ); commit; Why does my PC (core i7 920 with 6gb ram) only consume 9% cpu power and 60% ram when running these queries?

• How to remove duplicate records in a table?

  - by Mason Wheeler

  I've got a table in a testing DB that someone apparently got a little too trigger-happy on when running INSERT scripts to set it up. The schema looks like this: ID UNIQUEIDENTIFIER TYPE_INT SMALLINT SYSTEM_VALUE SMALLINT NAME VARCHAR MAPPED_VALUE VARCHAR It's supposed to have a few dozen rows. It has about 200,000, most of which are duplicates in which TYPE_INT, SYSTEM_VALUE, NAME and MAPPED_VALUE are all identical and ID is not. Now, I could probably make a script to clean this up that creates a temporary table in memory, uses INSERT .. SELECT DISTINCT to grab all the unique values, TRUNCATE the original table and then copy everything back. But is there a simpler way to do it, like a DELETE query with something special in the WHERE clause?

• Google checkout - Order processing notification handler

  - by Kunal

  Hi I need to integrate google checkout on my website. I have successfully implemented the order placing and others stuff and using the sandbox I have tested that users can successfully add items to cart and and pay thereafter. I am using my own customized shopping cart written in php mysql. The last thing I need to do is pass the new order id to google checkout and receive notifications with the new order id as well as other data google sends. I know I have to setup a path to the handler script in my accounts. I did it in my sandbox account as well. But can't find a simple pice of code to get it done. Even if I use sample code from google, just cant figure out the format of the returned data in new order notification and also how to send custom data to the cart, which would come back with new order notifications? I am just lost on this. Please help!

• BeautifulSoup Parser Confusion - HTML

  - by lyngbym

  I'm trying to scrape some content off another site and I'm not sure why BeautifulSoup is producing this output. It is only finding a blank space inside the match, but the real HTML contains a large amount of markup. I apologize if this is something stupid on my part. I'm new to python. Here's my code: import sys import os import mechanize import re from BeautifulSoup import BeautifulSoup def scrape_trails(BASE_URL, data): #Get the trail names soup = BeautifulSoup(data) sitesDiv = soup.findAll("div", attrs={"id" : "sitesDiv"}) print sitesDiv def main(): BASE_URL = "http://www.dnr.state.mn.us/skiing/skipass/list.html" br = mechanize.Browser() data = br.open(BASE_URL).get_data() links = scrape_trails(BASE_URL, data) if __name__ == '__main__': main() If you follow that URL you can see the sitesDiv contains a lot of markup. I'm not sure if I'm doing something wrong or if this is just malformed markup that the script can't handle. Thanks!

• Implementing a live voting system

  - by Will Eddins

  I'm looking at implementing a live voting system on my website. The website provides a live stream, and I'd like to be able to prompt viewers to select an answer during a vote initiated by the caster. I can understand how to store the data in a mySQL database, and how to process the answers. However: How would I initially start the vote on the client-side and display it? Should a script be running every few seconds on the page, checking another page to see if a question is available for the user? Are there any existing examples of a real-time polling system such as what I'm looking at implementing?

• Is there an easy way in Python to wait until certain condition is true?

  - by Checkers

  I need to wait in a script until a certain number of conditions become true? I know I can roll my own eventing using condition variables and friends, but I don't want to go through all the trouble of implementing it, since some object property changes come from external thread in a wrapped C++ library (Boost.Python), so I can't just hijack __setattr__ in a class and put a condition variable there, which leaves me with either trying to create and signal a Python condition variable from C++, or wrap a native one and wait on it in Python, both of which sound fiddly, needlessly complicated and boring. Is there an easier way to do it, barring continuous polling of the condition? Ideally it would be along the lines of res = wait_until(lambda: some_predicate, timeout) if (not res): print 'timed out'

• Annoying Bug in banner cycle

  - by Davemof

  I have created a rotating banner script for a new site I'm developing View banner here(it rotates every 10 seconds) Unfortunately to the transition seems to be a biut buggy, and the image will fade out, show the same image again and then fade in the new one. I think I have made a simple error somewhere, but can't figure out where it is. the code used to cycle the banners is: In document ready: if ($('.home').length > 0){ $('<img width="100%" />').attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg').load(function(){ $('.hero').append( $(this) ); $('.hero img').fadeIn('medium').delay(10000).fadeOut('slow', loopImages); setHeroHeight(); }); } Outside document ready: function loopImages(){ homecount = homecount+1; if (homecount > 5){ homecount = 1; } $('.hero img') .attr('src', '/assets/img/backgrounds/home/hero'+homecount+'.jpg') .load(function(){ $('.hero img').fadeIn('fast')}).delay(10000).fadeOut('slow', loopImages); } Any help would be greatly appreciated Thanks Dave

• How do I run multiple ruby scripts sequentially on my local machine?

  - by marcamillion

  I have about 5 or 6 ruby scripts I want to run, right after each other. These are all on my local machine (OS X) and won't be run on a server. Each takes about 15 minutes to run, and I don't want to have to wait for each one to finish before running the others manually. Without using something as heavy as delayed_job or some other queueing gem, how can I achieve this? Or should I go through the hassle of setting up sidekiq or something else? Thanks. P.S. It would be nice to restart the script if one of them times out (I am doing web crawling, so keeping an HTTP connection open sometimes gives me issues) - which happens occasionally.

• Any way to chunk gzip with Apache and PHP

  - by donatJ

  I have a web application on a site that takes a while (~10 seconds) to complete a portion of the page near the bottom - it has been as optimized as it can be, and caching is not an option. We have compression enabled on the server via an .htaccess directive SetOutputFilter DEFLATE the problem is this causes the whole page to be held until completion before it starts outputting to the user, this is not optimal as the user sees nothing until the page completes. I have also tried it via the php ob_start("ob_gzhandler"); method. Currently I have a <FilesMatch > in my .htaccess restricting this specific script from being compressed. Basically my question is this - Is there a way to say chunk gzip or deflate so that the user gets it in pieces, so they can see that the page has begun loading?

• How to find foreign-key dependencies pointing to one record in Oracle?

  - by daveslab

  Hi folks, I have a very large Oracle database, with many many tables and millions of rows. I need to delete one of them, but want to make sure that dropping it will not break any other dependent rows that point to it as a foreign key record. Is there a way to get a list of all the other records, or at least table schemas, that point to this row? I know that I could just try to delete it myself, and catch the exception, but I won't be running the script myself and need it to run clean the first time through. I have the tools SQL Developer from Oracle, and PL/SQL Developer from AllRoundAutomations at my disposal. Thanks in advance!
