• Ruby Equivalent of Python Requests Library (HTTP Client)

  - by Hartator

  There is a library in python that I love called requests. requests is a http client build on urllib3, top-notch :) (http://docs.python-requests.org/en/latest/) I am looking for something similar in ruby, basically what I need is : Upload files support (multipart/form-data) Easy get/post Cookies can be passed from a response object to a request object (build manually login script) Stable and Flexible Sessions support (to not have to handle cookies manually if we don't have too) I've looked at Typhoeus, but the code example in the home page doesn't work (they have moved code along and the get method is not longer directly accessible like that), so it's not starting well! :) Curb seems nice and I like curl, there is alson RestClient which seems popular and em-http seems pretty fast according to benchmark. There is a aso Patron and CurlFu which I haven't have the time to try. And of course Net:Http. But it doesn't seems to have a main stream solution that everyone point. I think a lot of people have been in my situation and I wonder what they have choosen and why?

• Delaying emails in PHP to avoid exceeding server limit

  - by Andrew P.

  Okay, so here's my problem: I have a list of members on a website, and periodically one of the admins my site (who are not very web or tech savvy) will send a newsletter to the memberlist. My current memberlist is well over 800 individuals long. So, I wrote an email script that sends the email to the full memberlist, with the members listed in the Bcc header. However, I've discovered that my host server has a limit of 300 emails per hour, which I apparently exceed even though the members are listed in the Bcc field. (I wasn't previously aware that the behaviour of Bcc was to send separate emails for each name on the list...) After some thought, I've come to the conclusion that my only solution is to have my script send only the email to only the first 300 emails, wait an hour, and send a second email to the next three hundred, wait another hour, and so on until I've sent the email to the whole member list. Looking around on the internet, I've seen some other solutions people have come up with for delaying emails in PHP. Sleep() is obviously not an option, because I can't just leave the script open and running for 3 or four hours. I've seen some people suggest cron jobs, but I'm not sure how feasible it would be to create three new cron jobs every time I send an email, use them once, and then delete them afterward. The final (and what I think is the smartest) solution I've seen, is to have a table in my database to temporarily store the emails to be delayed and sent later, and then create a cron job that checks this sql table every hour or so, compares the timestamp of the row to the current timestamp, and then sends the email if an hour has passed. So I'm asking you all which method you would recommend. Is there an easier solution that I've completely looked over (aside from getting a different hosting plan. ha!), or is there a cleaner way to do it than the database / cron job approach? tl;dr: I have 800 emails to send in an hour on a server that limits me to 300/hr. Using PHP, find a way to get around this problem in a way that the person sending the email needs only to click "send."

• Scripts help FIND command via atime output to multiple files

  - by sswagner

  here is a script I have wrote that I need help with. in the script I do a find for any file that has not been access for over 30 days, 60, 90, 180, 270 & 365 days. This works just fine. however, this takes a few days just to finish the 30 day portion. it is scanning a NAS. (millions and millions of files) as you see, the 30 day information really holds all the data need for the rest of the scripts. the 60, 90, etc. portion of the script are just redoing the same effort as the 30 day portion, except for an extended time frame. it would save in this case weeks worth of re-scanning if some how the 60, 90 180, etc.. portions could just get its data from the 30 day output. this is where I am asking for help. the output is just like an ls -l command. and you can also see from the output below, there are multiple years in this output. the script is attached and printed below. total 24 -rw-r--r-- 1 root bin 60 Apr 12 13:07 config_file -rw-r--r-- 1 root bin 9 Apr 12 13:07 config_file.InProgress -rw-r--r-- 1 root bin 0 Apr 12 13:07 config_file.sids -rw-r--r-- 1 root bin 1284 Apr 19 10:41 rpt_file -rw-r--r-- 1 16074 5003 20083 Apr 26 2002 /nas/quota/slot_2/CR_APP002/eb_ora_bin1/sun8/product/9.2s/oem_webstage/oracle/sysman/qtour/console/dat1_01.gif -rw-r--r-- 1 16074 5003 20088 Apr 26 2002 /nas/quota/slot_2/CR_APP002/eb_ora_bin1/sun8/product/9.2s/oem_webstage/oracle/sysman/qtour/console/set1_04.gif -rw-r--r-- 1 16074 5003 2008 Apr 26 2002 /nas/quota/slot_2/CR_APP002/eb_ora_bin1/sun8/product/9.2s/oem_webstage/oracle/sysman/qtour/oapps/get2_03.htm -rw-r--r-- 1 16074 5003 20083 Apr 26 2002 /nas/quota/slot_2/CR_APP002/eb_ora_bin1/sun8/product/9.2s/oem_webstage/oracle/sysman/qtour/oapps/per1_01.gif any help is appreciated. these are linux distro boxes, so I am sure perl is on there too if needed..

• Django and ajax image file upload errors and csrf

  - by sharkfin

  I tried out Alex Kuhl's ajax script to upload images to Django 1.4. My first question is why I'm getting an empty page with firebug telling me I have two errors: fileuploader.js (line 4): syntax error <!DOCTYPE html> In my template html: qq is not defined var uploader = new qq.FileUploader( { Here is my entire html file for it: http://pastebin.com/NjbV5gMn This post suggests that either some script has 404'd or the src attribute is empty, which would cause the doctype error. But that doesn't seem to be the case here. As for why qq is not defined, I'm not sure what is wrong. Django can clearly find the fileuploader.js just fine from my static folder. My second question is why the ajax code uses {{ csrf_token }} instead of {% csrf_token %}. But if I use {% csrf_token %}, I get the firebug error: missing } after property list 'csrf_token': '<div style='display:none'<input type='hidden' name='csrfmiddlewaretoken' value='Cx0zFFak6OLgrHiAnFa3k4BPDmn4BgoT' /</div',

• Determining which JavaScript/CSS browser features are required

  - by Alan Neal

  My website uses a variety of technologies, such as JQuery, new CSS definitions (e.g., moz-selection, -webkit-user-select), etc. The site works perfectly with Google Chrome and Safari, but has some quirkiness in Firefox, IE, and some of the other browsers. I want to write a script to check for necessary browser features but, with several thousand lines of code and CSS definitions, I'm not certain which features I should be looking for. Is there some sort of online analysis (similar to how JSLint operates) that would tell me which features my script and CSS files need? Are there tools (like FireBug) that provide this info?

• Add client-side events to ASP.Net custom control at runtime

  - by nw

  I'm building an ASP.net custom control that implements IScriptControl. I would like other users of my control to be able to assign client-side event handlers to the control. Unfortunately the JS generated by IScriptControl is always injected at the very bottom of the rendered page (see below), so any attempt to assign an event handler in the ASPX page fails because the code executes too early. ... <script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); Sys.Application.add_init(function() { $create(MyNamespace.MyControl, {}, null, null, $get("my_control_id")); }); //]]> </script> </form> What's the right way to assign an event handler to the instantiated control upon page load?

• Fastest method for SQL Server inserts, updates, selects from C# ASP.Net 2.0+

  - by Ian

  Hi All, long time listener, first time caller. I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

• Issues using $.ajax

  - by Nimbuz

  I want to load the lightbox javascript only when a certain condition is satisfied so I'm loading it using $.ajax like so: $.ajax({ url: "../static/js/lightbox.js", dataType: 'script', cache: true, success: function() { alert('loaded'); $("a.lightbox").lightbox({ opacity: "0.6", width: "940" }); }}); I see the "loaded" alert but the lightbox does not work. However, when I load the file directly (script src) from the HTML, lightbox works. How do I fix this? Many thanks for your help.

• How can I get Hudson to be able to access JUnit?

  - by Bedwyr Humphreys

  I've got Hudson running on TOMCAT, it can build my Netbeans project using the ant build.xml, but it won't run any of my unit tests because of what I assume is a problem with the classpath: package org.junit does not exist [javac] import org.junit.After; [javac] ^ But I've got the junit-4.8.1.jar on the classpath in /etc/environment and I can successfuly run the junit tests from a console using java org.junit.runner.JUnitCore org.junit.tests.AllTests My CLASSPATH is set to /home/bedwyr/junit4.8.1/junit-4.8.1.jar:. Am I going wrong somewhere or is there anything else I need to set? [edit] What I did was to export/include (using the ide) all libraries (including Junit) hudson then reads all it needs from the subversion repo. I then ran into an issue with exposing hudson to the internet, and pretty soon gave up on tomcat on ubuntu server (again, to do with the tomcat security manager) - glassfish is a lot smoother and that's where I am now - apache front end with ajp_proxy to hudson on glassfish.

• Resources check

  - by Chris

  hey I am frequently uploading my XCode iPhone projects to an svn repository to be build on another machine. My problem is that when I add resources to my project sometimes I forget to add the resource as relative to the project. I know one answer is to be more careful (not easy when your tired!) but if there was a way to run a script to check my resource paths are relative when I build and warn me if they are not it would be a great time saver for me. How would I go about doing this? Thanks Chris

• module compiled with swig not found by python

  - by openbas

  Hello, I've a problem with SWIG and python. I've a c-class that compiles correctly, but the python script says it can't find the module. I compile with: swig -c++ -python codes/codes.i g++ -c -Wall -O4 -fPIC -pedantic codes/*.cc g++ -I/usr/include/python2.6 -shared codes/codes_wrap.cxx *.o -o _codes.so This gives me a _codes.so file, as I would expect, but then I have this python file: import sys import codes (rest of the code omitted) It gives me: Traceback (most recent call last): File "script.py", line 3, in <module> import codes ImportError: No module named codes According to http://www.swig.org/Doc1.3/Introduction.html#Introduction_nn8 this is all I should have to do... The files are in the same directory, so the path should not be a problem ?

• Google Maps integration with JSON - CircularReferenceError

  - by JZ

  I'm working on Rails 3.0.0.beta2, following Advanced Rails Recipes "Recipe #32, Mark locations on a Google Map" and I hit a road block. The following code is returning a "ActiveSupport::JSON::Encoding::CircularReferenceError" "object references itself" at line 3. This code represents the /layouts/maps.html.erb file <% if @maps -%> <script type="text/javascript"> var maps = <%= @maps.to_json %>; </script> <% end -%> This is my first attempt at rendering JSON, and I don't know how to debug this problem. Do you have experience with this? What could cause this problem? Thank you in advance!

• Getting a Target to run BEFORE anything else runs when building from Visual Studio

  - by damageboy

  Hi, I'm trying to get a one-time costly target to run only when building a certain top-level project (that has many dependencies). I have no problem on getting this working from plain msbuild / command line build. I do this with setting and InitialTargets on the project, or alternatively with < BeforeBuild /. The tricky part is with Visual Studio. When I build the same project from VS. VS runs the dependencies before even invoking my .csproj, so my target (which affects how the other projects are built) doesn't get to run until they have already been built. Is there someway to force VS to run a target before invoking the dependencies? I'm currently working around this, by running the same costly target from my most low-level project (the one that get's always built...) by using: Condition=" $(BuildingInsideVisualStudio) " Any ideas on how to get this done "properly"? Again, I'm looking for a solution that will work FROM VS.

• "a valid provisioning file for this executable was not found" in XCode

  - by dbonneville

  I'm trying to submit my second app to the App Store. I've followed all the instructions to the best of my knowledge, but I keep getting this error when I try to build and run: "a valid provisioning file for this executable was not found" I'm letting XCode auto select the profile automatically. The one I'd like to select is greyed out. But the dropdown selection in the Build tab of the Target window says "profile doesn't match application identifier" The other thing I don't get about this is that the selection dropdown shows "com.mycompany.myapp" and then "ABCDEDFG.com.mycompany.myapp" (both of those made up) so that I see they don't match. I have the unique identifier profile installed in the Organizer and in plist file. I'm totally confused. I have followed the instructions in my book a few times and just can't get it.

• How to solve Python memory leak when using urrlib2?

  - by b_m

  Hi, I'm trying to write a simple Python script for my mobile phone to periodically load a web page using urrlib2. In fact I don't really care about the server response, I'd only like to pass some values in the URL to the PHP. The problem is that Python for S60 uses the old 2.5.4 Python core, which seems to have a memory leak in the urrlib2 module. As I read there's seems to be such problems in every type of network communications as well. This bug have been reported here a couple of years ago, while some workarounds were posted as well. I've tried everything I could find on that page, and with the help of Google, but my phone still runs out of memory after ~70 page loads. Strangely the Garbege Collector does not seem to make any difference either, except making my script much slower. It is said that, that the newer (3.1) core solves this issue, but unfortunately I can't wait a year (or more) for the S60 port to come. here's how my script looks after adding every little trick I've found: import urrlib2, httplib, gc while(true): url = "http://something.com/foo.php?parameter=" + value f = urllib2.urlopen(url) f.read(1) f.fp._sock.recv=None # hacky avoidance f.close() del f gc.collect() Any suggestions, how to make it work forever without getting the "cannot allocate memory" error? Thanks for advance, cheers, b_m update: I've managed to connect 92 times before it ran out of memory, but It's still not good enough. update2: Tried the socket method as suggested earlier, this is the second best (wrong) solution so far: class UpdateSocketThread(threading.Thread): def run(self): global data while 1: url = "/foo.php?parameter=%d"%data s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(('something.com', 80)) s.send('GET '+url+' HTTP/1.0\r\n\r\n') s.close() sleep(1) I tried the little tricks, from above too. The thread closes after ~50 uploads (the phone has 50MB of memory left, obviously the Python shell has not.) UPDATE: I think I'm getting closer to the solution! I tried sending multiple data without closing and reopening the socket. This may be the key since this method will only leave one open file descriptor. The problem is: import socket s=socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.connect(("something.com", 80)) socket.send("test") #returns 4 (sent bytes, which is cool) socket.send("test") #4 socket.send("test") #4 socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns the number of sent bytes, ok socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("test") #returns 0, strange... *: error message: 10053, software caused connection abort Why can't I send multiple messages??

• Implementing a configurable factory

  - by Decko

  I'm having difficulties finding out how to implement a 'configurable' behavior in a factory class in PHP. I've got at class, which takes another class as an argument in its constructor. The argument class could take a number of arguments in its constructor. An instance of my main class could look something like this $instance = new MyClass(new OtherClass(20, true)); $instance2 = new MyClass(new DifferentClass('test')); This is rather clumsy and has a number of problems and therefore I would like to move this into a factory class. The problem is that this factory somehow needs to know how to instantiate the argument class, as this class can have any number of arguments in the constructor. Preferably I would like to be able to do something like this $instance = Factory::build('OtherClass'); $instance2 = Factory::build('DifferentClass'); And let the factory retrieve the arguments from a configuration array or similar. Is there a proper solution to this problem?

• Why ????? is displayed instead of non-english characters?

  - by smhnaji

  I first created a simple HTML page that uses UTF-8 as its character encoding. Then I moved the HTML content as a view in codeigniter and it was still ok (I had used non-english characters that were ok as always) I added a simple dynamic functionality (there is a contact us form in it that emails users feedback to site admin). Please note that the characters were ok at localhost (which is a LAMP server running on Ubuntu 12.04 LTS) Strange is that when I uploaded the app to server, all persian characters are shown as ???? (For example ??? (which means Name) is shown ??? and so so...) I have not even connected to mysql or any other DBMS. It's the only page in the website (it's more an under construction page) and nothing else has been used in it. Maybe I should state that I have also used session library to thank the user after his feedback was sent to admins, nothing else. I have really no idea about the problem. UPDATE Now I can see that the problem is only with cPanel. On Directadmin I can see that everything is normal. Both Chromium and Firefox DO use UTF-8 as page's character encoding. URL is http://WEBSITE.COM/dmf/dynamic/ (dmf is the abbreviation of the project name!). There is nothing non-english in the URL. The page's code is as follows: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>??? ???????</title> <link rel="stylesheet" type="text/css" href="<?php echo base_url('template/css/style.css'); ?>" /> <!-- 1. jquery library --> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"> </script> <!-- 2. flowplayer --> <script src="http://releases.flowplayer.org/5.1.1/flowplayer.min.js"></script> <!-- 3. skin --> <link rel="stylesheet" type="text/css" href="http://releases.flowplayer.org/5.1.1/skin/minimalist.css" /> </head> <body> <div id="wrapper"> <header> <h1>??? ???????</h1> </header> <section id="box-container"> <?php echo form_open('contact', "id='contact-us'"); echo form_fieldset('???? ?? ??'); if ($this->session->userdata('mailsent')) { echo '<div>??????? ???? ??? ????? ??</div>'; $this->session->sess_destroy(); } echo '<input tabindex="1" id="name-in" value="???" type="text" name="name"/> <input tabindex="2" id="mail-in" value="?????" type="email" name="email"/> <textarea tabindex="3" id="content-in" name="message">???????</textarea> <input tabindex="4" id="submit" type="submit" value="?????" />'; echo '<div class="clear"></div>'; echo form_fieldset_close(); echo form_close(); ?> <div id="sms-comp"> <h2>?????? ??????</h2> <p> <span id="comp-title">?? ??? ????</span> ???? ??????? ???? ??? </p> </div> <div id="last-program"> <h2>?????? ????? ??????</h2> <div class="flowplayer"> <video id="my_video_1" width="212" height="126" poster="<?php echo base_url('template/images/img.jpg'); ?>" controls="controls" src="http://archive.org/download/Pbtestfilemp4videotestmp4/video_test.ogv" type='video/mp4'> </video> </div> </div> <div class="clear"></div> </section> </div> <footer> ????? ? ????? : <a href="http://powered-by.com/" target="_blank">????? ???</a> </footer> </body> </html>

• Query size of block device file in Python

  - by ??O?????

  Hello. I have a Python script that reads a file (typically from optical media) marking the unreadable sectors, to allow a re-attempt to read said unreadable sectors on a different optical reader. I discovered that my script does not work with block devices (e.g. /dev/sr0), in order to create a copy of the contained ISO9660/UDF filesystem, because os.stat().st_size is zero. The algorithm currently needs to know the filesize in advance; I can change that, but the issue (of knowing the block device size) remains, and it's not answered here, so I open this question. I am aware of the following two related SO questions: Determine the size of a block device (/proc/partitions, ioctl through ctypes) how to check file size in python? (about non-special files) Therefore, I'm asking: in Python, how can I get the file size of a block device file?

• Creating my own SAP dashboard/reporting tool for mobile

  - by novwareman

  Hi! Is it possible to create my own mobile dashboard, reporting tool for SAP? I understand the standard components to be used for this purpose are: Business Objects Enterprise Server XI - this provides reporting functionalities for SAP Business Objects Mobile Server - this connects to Enterprise Server and optimizes reports stored there for mobile devices Mobile Web Browser or Mobile Business Objects Report Client - for viewing the reports I don't intend to purchase the components mentioned above. I only want to know if it's feasible to build my own solution. I am familiar with BAPI's to retrieve data from SAP. What is the proper approach to build an SAP reporting tool? Thank you!

• Kill a Perl system call after a timeout

  - by Fergal

  I've got a Perl script I'm using for running a file processing tool which is started using backticks. The problem is that occasionally the tool hangs and It needs to be killed in order for the rest of the files to be processed. Whats the best way best way to apply a timeout after which the parent script will kill the hung process? At the moment I'm using: foreach $file (@FILES) { $runResult = `mytool $file >> $file.log`; } But when mytool hangs after n seconds I'd like to be able to kill it and continue to the next file.

• How to update the session values on partial post back and how to make Javascript use the new values

  - by Mano

  The problem I am facing is the I am passing values to javascript to draw a graph using session values in the code behind. When page loads it take the value from the session and creates the graph, when I do partial post back using a Update Panel and Timer, I call the method to add values to the session and it does it. public void messsagePercentStats(object sender, EventArgs args) { ... if (value >= lowtarg && value < Toptarg) { vProgressColor = "'#eaa600'"; } else if (value >= Toptarg) { vProgressColor = "'#86cf21'"; } Session.Add("vProgressColor", vProgressColor); Session.Add("vProgressPercentage", "["+value+"],["+remaining+"]"); } } I use the update panel to call the above method <asp:ScriptManager ID="smCharts" runat="server" /> <asp:UpdatePanel runat="server" ID="Holder" OnLoad="messsagePercentStats" UpdateMode="Conditional"> <ContentTemplate> <asp:Timer ID="Timer1" runat="server" Interval="5000" OnTick="Timer_Tick" /> and the timer_tick method is executed every 5 seconds protected void Timer_Tick(object sender, EventArgs args) { ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "r.init();", true); ResponseMetric rm = new ResponseMetric(); Holder.Update(); } I use ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "r.init();", true); to call the r.init() Java script method to draw the graph on post back and it works fine. Java Script: var r = { init : function(){ r = Raphael("pie"), data2 = [<%= Session["vProgressPercentage"] %>]; axisx = ["10%", "20%"]; r.g.txtattr.font = "12px 'Fontin Sans', Fontin-Sans, sans-serif"; r.g.barchart(80, 25, 100, 320, data2, { stacked: true, colors: [<%= Session["vProgressColor"] %>,'#fff'] }); axis2 = r.g.axis(94, 325, 280, 0, 100, 10, 1); } } window.onload = function () { r.init(); }; This Java Script is not getting the new value from the session, it uses the old value when the page was loaded. How can I change the code to make sure the JS uses the latest session value.
