• Replacing substring in a string

  - by user177785

  I am uploading a image file to the server. Now after uploading the file to the server I need to rename the file with an id, but the extension of the file should be retained. Eg: if I upload the file image1.png then my server script should retain the extension .png. But I need to change the substring to some other substring (primary key of db). image1.png should be renamed to 123.png image2.jpg should be renamed to somevalue.jpg The image can be of any extension like .png, .jpg, .jpeg etc. I want to rename then in such a way that the image/file extension should be retained.

• Scripting language to embed into a Java server application

  - by Alexey Kalmykov

  I want to make a business logic of server side Java application as a set of scripts. So I need from a scripting engine: Maximum Java interoperability (i.e. Spring framework) Script reloading and recompiling Easy DB access from scripting language Clear and simple syntax (some DSL capabilities would be nice to have), easy learning curve for non-hardcore developers Performance and stability I had some experience in the similar project with Rhino and it was pretty good. But I want to see if there is something better. Currently I'm looking into Groovy. JRuby and Jython are a bit more complex than I need for this task. Any other suggestion? What to take into consideration?

• How can I check if a binary string is UTF-8 in mysql?

  - by Piotr Czapla

  I've found a Perl regexp that can check if a string is UTF-8 (the regexp is from w3c site). $field =~ m/\A( [\x09\x0A\x0D\x20-\x7E] # ASCII | [\xC2-\xDF][\x80-\xBF] # non-overlong 2-byte | \xE0[\xA0-\xBF][\x80-\xBF] # excluding overlongs | [\xE1-\xEC\xEE\xEF][\x80-\xBF]{2} # straight 3-byte | \xED[\x80-\x9F][\x80-\xBF] # excluding surrogates | \xF0[\x90-\xBF][\x80-\xBF]{2} # planes 1-3 | [\xF1-\xF3][\x80-\xBF]{3} # planes 4-15 | \xF4[\x80-\x8F][\x80-\xBF]{2} # plane 16 )*\z/x; But I'm not sure how to port it to MySQL as it seems that MySQL don't support hex representation of characters see this question. Any thoughts how to port the regexp to MySQL? Or maybe you know any other way to check if the string is valid UTF-8? UPDATE: I need this check working on the MySQL as I need to run it on the server to correct broken tables. I can't pass the data through a script as the database is around 1TB.

• Looking for a lean WYSIWYG inline editor for CMS projects that includes an image upload feature?

  - by Roeland

  Hey guys, I am looking to find a lean WYSIWYG inline editor. The main required feature is image uploading. A simple way to upload an image to the server and use it in the content being editted. I have come across a whole bunch of editors but nothing I liked so far. I am looking for something open source and free. So far I have checked out TinyMCE which is free.. untill you need image uploading capabilities. Ckeditor looks great.. uses jquery.. but requires you to have your own server side script to upload images. They barely give any documentation on how to do this. There were a few others, but the bottom line was that I cant find anything that is simple with out of the box image uploading capabilities. Thanks for any advice you may give!

• Are google chrome extension "content" scripts sandboxed?

  - by jabapyth

  I was under the impression that the content_scripts were executed right on the page, but it now seems as though there's some sandboxing going on. I'm working on an extension to log all XHR traffic of a site (for debugging and other development purposes), and in the console, the following sniff code works: var o = window.XMLHttpRequest.prototype.open; window.XMLHttpRequest.prototype.open = function(){ console.log(arguments, 'open'); return o.apply(this, arguments); }; console.log('myopen'); console.log(window, window.XMLHttpRequest, window.XMLHttpRequest.prototype, o, window.XMLHttpRequest.prototype.open); This logs a message everytime an XHR is sent. When I put this in an extension, however, the real prototype doesn't get modified. Apparently the window.XMLHttpRequest.prototype that my script is seeing differs from that of the actual page. Is there some way around this? Also, is this sandboxing behavior documented anywhere? I looked around, but couldn't find anything.

• How to wrap Plone authentication around a third-party servlet?

  - by smocking

  We're using Plone to serve up some third-party middle-ware. Unfortunately the middle-ware has a particular servlet that gets invoked from a Java applet and doesn't do any kind of authentication. I would like to firewall this off and somehow wrap authentication around it, preferably using the existing session that users will have on Plone. My first idea was to configure nginx (which we're using as the reverse proxy) to check the cookie and only proxy if the user has a valid session (along the lines of this example). However, how to check the session ID against Plone, since it's all stored in the Zope database? Alternatively we could have a Plone python script that basically passes everything along to the back-end after authenticating, but I'm not sure how to do that. Any suggestions? Or alternative ideas?

• How secure is a PostgreSQL database if my server is stolen?

  - by orokusaki

  If I have a server with a database if top secret data in PostgreSQL and my password is practically impossible to crack (128 character string of all sorts of weird chars, generated by hand). The server password is also uncrackable in theory (basically, ignore the possibility of a password crack on the DB). Aside from a password crack, how easy is it to get the data out of this database? Assumptions: Only the DB exists on the server. There is no password in a PHP script or anything like that The person who has the server is a computer / DB / hard-drive recovery expert I'm not using any hard-drive encryption or anything out of the norm for protection I'm trying to understand the risks involved with somebody gaining physical access to my server's hard-drives.

• Averaging corrupted images to eliminate the noise in Matlab

  - by Mertie Pertie

  Hi all As you can get it from the title, I want to average some .jpg images which are corrupted by zero-mean Gaussian additive. After searching over internet, I figured out to add image matrices and divide the sum by the # of matrices. However the resultant image is totally black. Normally when the number of image increases then the resultant image gets better. But When I use more images it gets darker. I am using 800x600 black and white images with .jpg ext Here is the script I used; image1 = imread ('PIC1.jpg'); image2 = imread ('PIC2.jpg'); image3 = imread ('PIC3.jpg'); image4 = imread ('PIC4.jpg'); sum = image1 + image2 + image3 + image4; av = sum / 4; imshow(av); Thanks in advance

• System_Daemon and shell_exec

  - by Jesse

  Hey Everyone, I've set up a daemon (daemon.php) using PEAR's System_Daemon which waits for something to appear in the database. Once something is there, the daemon gets enough information and sends it out to another script (execute.php) using the shell_exec command this way I'm not worried about waiting for a response and holding up the daemon. Both of the scripts work fine alone and I'm even able to call shell_exec before calling System_Daemon::start(); . However, if I trying calling it AFTER System_Daemon::start();, then I get an Access Denied only when outputting to a file. I'm still new to Daemons in general, so any ideas or thoughts would be great! Thanks Guys!

• Help with Pixel Shader effect for brightness and contrast

  - by Hans

  What is a simple pixel shader script effect to apply brightness and contrast? I found this one, but it doesn't seem to be correct: sampler2D input : register(s0); float brightness : register(c0); float contrast : register(c1); float4 main(float2 uv : TEXCOORD) : COLOR { float4 color = tex2D(input, uv); float4 result = color; result = color + brightness; result = result * (1.0+contrast)/1.0; return result; } thanks!

• Download and write .tar.gz files without corruption.

  - by arbales

  I've tried numerous ways of downloading files, specifically .zip and .tar.gz, with Ruby and write them to the disk. I've found that the file appears to be the same as the reference (in size), but the archives refuse to extract. What I'm attempting now is: Thanks! def download_request(url, filePath:path, progressIndicator:progressBar) file = File.open(path, "w+") begin Net::HTTP.get_response URI.parse(url) do |response| if response['Location']!=nil puts 'Direct to: ' + response['Location'] return download_request(response['Location'], filePath:path, progressIndicator:progressBar) end # some stuff response.read_body do |segment| file.write(segment) # some progress stuff. end end ensure file.close end end download_request("http://github.com/jashkenas/coffee-script/tarball/master", filePath:"tarball.tar.gz", progressIndicator:nil)

• Window bounds set on window using AppleScript in OS X are being ignored

  - by Jesse

  I am trying to create a small AppleScript to create and move some Terminal windows around my screen. The problem I am running into is that in some cases, it seems that OS X is ignoring the bounds I am setting. Using the AppleScript Editor: tell application "Terminal" to set the bounds of the first window to {0, 50, 600, 700} tell application "Terminal" to get the bounds of the first window Shows the following in the Event Log: tell application "Terminal" activate set bounds of window 1 to {0, 50, 600, 700} get bounds of window 1 --> {0, 22, 600, 672} end tell Result: {0, 22, 600, 672} Visually inspecting the window that is created when the script runs shows that Result bounds are the ones being used by the window. Any ideas?

• jQuery wait for ajax call to be over before continuing

  - by Flo

  Hi all, I have a problem with a jQuery ajax call. I need to wait for the call to be finished in order to return a value. However, the script seems to jump ahead and not wait for the call to be over. my function then returns "undefined". I have tried to use the .ajax() method and set the value of async to false, but this would not work either. I could I get my function to return the value that I could through the ajax call? Thank you! Here is the code: function get_rsrce_name(){ jQuery.post( '<?php echo admin_url( 'admin-ajax.php' ); ?>', { action :'my_action', option_rsrce : 'option_rsrce' }, function( data ) { output = data.option_name; }, "json" ); return output; }

• Python+Windows+GStreamer = Impossible (for me)?

  - by james

  Hi :) essentially, my problem is, ater a long time searching, finding only this other question, i decided i was just going to ask my own... i am on windows 7 with python 2.6 and ossbuild GStreamer, but i am trying to get the python binding for it, and struggling. i have got gst-python from http://gstreamer.freedesktop.org/src/gst-python/ but as my eyes and research tell me, it does not work in the setup.py way, and the other question has a link to a site that he says has a binary avaiable, which no longer does, http://www.gstreamer-winbuild.ylatuya.es/doku.php?id=download and even the sdk is gone, and ossbuild dont seem to have anything useful either. so essentially, my question is, can anyone tell me a method, however convoluted, of getting my setup so if i write a script for (py)gst, with an import gst it will work? not the best of explanations... im tired k? xxx :)

• Windows environment variables change when opening command line?

  - by Jakobud

  Sometimes when I change my environment variables in Windows, and then use software the depends on those variables, they are not properly updated. And good example is to change a variable, then open up Windows Command Line and echo the variable and see that it hasn't been changed, even though you properly changed it in the Environment Variables window. Another example I'm dealing with right now: I've been using Python 2.4.x for a while for a project, which uses the env var PYTHONPATH who's value has been: C:\Python24;C:\Python24\lib Today I installed Python 2.5.x for the project. I changed my PYTHONPATH to be: C:\Python25;C:\Python25\lib When I use Python 2.5 to run a script and do this: import sys print sys.path It prints: 'C:\\PYTHON24', 'C:\\PYTHON24\\lib' (and some other Python 2.5 related default installation paths) So clearly, the old PYTHONPATH environment variable changes aren't really sticking.... Does anyone know why this happens and how to fix it?

• php database session handling problem in IE8!

  - by psyb0rg

  I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

• Php efficiency question --> Database call vs. File Write vs. Calling C++ executable

  - by JP19

  Hi, What I wish to achieve is - log all information about each and every visit to every page ofmy website (like ip address, browser, referring page, etc). Now this is easy to do. What I am interested is doing this in a way so as to cause minimum overhead (runtime) in the php scripts. What is the best approach for this efficiency-wise: 1) Log all information to a database table 2) Write to a file (from php directly) 3) Call a C++ executable, that will write this info to a file in parallel [so the script can continue execution without waiting for the file write to occur ...... is this even possible] I may be trying to optimize unnecessarily/prematurely, but still - any thoughts / ideas on this would be appreciated. (I think efficiency of file write/logging can really be a concern if I have say 100 visits per minute...) Thanks & Regards, JP

• Linux application that bundles multiple incoming audio and video streams into one container file?

  - by StackedCrooked

  I've been assigned to implement a video on-demand service for a local university. Different aspects of the lectures (video, audio, screen cast, white board) will be recorded. During a lecture all these data streams arrive at one Linux server. This server should transcode and bundle all these streams into one container (Matroska) file. My options seem to be: Write a GStreamer application do something with FFMPEG do something with VLC ...? Has anyone done something similar in the past? Can you recommend something? Edit For those interested, here are a few of my findings: Matroska is not a good format for streaming (it's possible, but it's not its primary intent) For Flash streaming you can use MPEG4 If you want to combine different videos into one video where each subvideo occupies a rectangular portion of the total screen, then this GStreamer script is useful (I found it on this blog post). Desktop capture works fine with VLC

• Determine IP# of domain from client browser

  Greetings all, I would very much like to determine the IP# of a domain from client script. It's for use in a testing application to determine whether or not a certain domain is set to a QA address as opposed to the address live on the . The testing machine will have it's host file set to resolve a domain to the QA address. Pinging from the server won't help since the server is getting the public DNS address. Is this possible in JavaScript? Maybe a Flash could do the trick?

• How to retrieve all errors and messages from a query using ADO

  When a SQL batch returns more than one message from e.g. print statements, then I can only retrieve the first one using the ADO connection's Errors collection. How do I get the rest of the messages? If I run this script: Option Explicit Dim conn Set conn = CreateObject("ADODB.Connection") conn.Provider = "SQLOLEDB" conn.ConnectionString = "Data Source=(local);Integrated Security=SSPI;Initial Catalog=Master" conn.Open conn.Execute("print 'Foo'" & vbCrLf & "print 'Bar'" & vbCrLf & "raiserror ('xyz', 10, 127)") Dim error For Each error in conn.Errors MsgBox error.Description Next Then I only get "Foo" back, never "Bar" or "xyz". Is there a way to get the remaining messages?

• Running Python code from Java program, shoudl i be doing this?

  - by Space Rocker

  i have a scenario where i draw a network and set all it's paraments on swing based gui, after that i have to translate this network into a python based script which another framework reads and realize this network in the form of virtual machines. As an example have look here: from mininet.topo import Topo, Node class MyTopo( Topo ): def *__init__*( self, enable_all = True ): super( MyTopo, self ).__init__() Host = 1 Switch = 2 self.add_node( Switch, Node( is_switch=True ) ) self.add_node( Host, Node( is_switch=False ) ) self.add_edge( Host, Switch ) self.enable_all() topos = { 'mytopo': ( lambda: MyTopo() ) } It simply connects a host to a switch and realize this topology on mininet framework. Now for now in order to realize the drawn network on java GUI here is what i am doing: I simply take the information from GUI and creates a new python file like the one above using java code and then run this file in mininet, which works fine somehow. I want to know, is this the correct and robust way how i am doing this or should i be looking further into java-python bridge like scenarios to be more effective or so as to say more professional.
