• Amazon AWS s3fs mount problem on Fedora 14

  - by Alex

  I successfully compiled and installed s3fs (http://code.google.com/p/s3fs/) on my Fedora 14 machine. I included the password credentials in /etc/ as specified in the guide. When I run: sudo /usr/bin/s3fs bucket_name /mnt/bucket_name/ it runs successfully. (note: the bucket name is the same as the folder name in /mnt/). When I run ls in /mnt/ I get the error "ls: cannot access bucket_name: Permission denied". When I run sudo chmod 640 /mnt/bucket_name I get "chmod: changing permissions of `bucket_name': Input/output error". When I reboot the machine I can access the folder /mnt/bucket_name normally but it is not mapped to the s3 bucket. So, basically I have two questions. 1) How do I access the folder (/mnt/bucket_name) as usual after I mount it to the s3 bucket and 2) How can I keep it mounted even after machine restart. Regards

• What would the conditional statement be to filter these inputs?

  - by dmanexe

  I have a page with a form, and on the form are a bunch of input check boxes. In the following page, there's the following code to process the inputs from the page before (which are set as an ID). <? $field = $this->input->post('measure',true); $totals = array(); foreach($field as $value): $query = $this->db->get_where('items', array('id' => $value['input']))->row(); $totals[] = $query->price; ?> #HTML for displaying estimate output here <?php endforeach; ?> How would I have the loop run conditionally only if there was a check on the input on the page before?

• Zend Framework: Flash Messenger, add a message from the model

  - by Dan

  Any idea on how best to add a message to flash messenger from the model? As FlashMessenger is an action helper, this seems not to be possible, so the obvious solution is to create an internal message object in the model, and return that to the controller from where you can use addMessage(). But if you want to return something else as well, this falls down. Another idea is an additional session namespace for these internal messages, which is then merged in with the Flash Messenger namespace messages at output time? Anyone have any thoughts or experience on this? Cheers.

• What open source database platform is most easily transferred from my personal machine into a window

  - by Tom

  I would like eventual interaction with MS Dynamics SL and/or MindTouch Core (running on WMware) for eventual intranet and/or internet display. I guess I am asking for front and back end recommendations for a database I am constructing, but since this is my first major project I would greatly appreciate any help and advice. I would also love an opportunity to learn a new language so the code base could be in any language. I do have a few more related questions for discussion; What is the viability of using Google hosting to provide the service to the public for free? Should I implement plone or another CMS if I have a large amount of output? Is there a structuring questionnaire or standards publication I could reference? Does UML diagramming provide additional options for portability? Thank you.

• Generating VS 2005 .vcproj's by hand

  - by Kevin

  I'm working on a script that generates Visual Studio 2005 C++ project files (.vcproj). The script reads a makefile, then spits out a c++ project. INPUT: makefile --- OUTPUT: VS 2005 c++ project (.vcproj) However, when I try to build the auto-generated project in VS 2005, error outputs: "Unspecified Error." Evidently, I am not generating the VS 2005 .vcproj file correctly. Assuming that my c++ project file was malformed, I opened up VS 2005 and made a new C++ project. I actually copied the good, VS 2005-created project file to my non-working, malformed project file. I replaced the Name, Reference Includes (.libs), Compile Includes (.cc, .c), etc. in the good VS 2005 project with my malformed project file's information. However, I still cannot get VS 2005 to compile my .vcproj. Perhaps VS 2005 is very particular about the content of its .vcproj's? Please give me advice on how to manually generate a VS 2005 .vcproj. Thanks!

• Re-send POST request easily - what tools?

  - by Fabien

  I am looking for an easy way to re-send POST request to the server within the browser mainly for debug purposes. Say you have a XHR request which contains POST parameters that is to be send to the server. After having changed the script on the server side, you would like to resent the very same request for analyzing the output. What tool could help? I guess it is a browser's extension. I already tried extension Tamper Data for Firefox which does the job as you can "Replay in browser". But for my taste, it is not enough straight forward, as there are 3 - 4 clicks to get the result of the request. Unfortunately, curl would not be suitable for my needs as my application has a session's cookie.

• ShoutCast over SSL

  - by Honus Wagner

  So I've gone ahead and set up my ShoutCast server DNAS and set my DSP in Winamp on my host computer. The server listens on port 8000, so per some instructions I installed an output plugin for winamp (Shoutcast DSP) and used 8000 and the password to connect. Server accepts the connection. Now, what the heck do I do now? My host computer is SSL secured and the DNAS server is installed within the secure web directory (if that matters). My desired end result is that I want to listen to my ShoutCast setup at home (host computer) from any computer. I try browsing to my ip address and port 8000 (without using HTTPS) and it comes back with nothing. If I browse with HTTPS://my.server.com:8000, I get Error code: ssl_error_rx_record_too_long) Have I completely missed something, or am I just a total moron? Thanks.

• Create unordered list tree menu from data stored in an table with the adjacency list model...php

  - by Ronedog

  I need to create a tree menu of "nth" subcategories. I settled on using the adjacency list model for my table structure, because I won't be updating this table very much and this seemed the easiest to implement for my use. I want to style the output using "ul" and "li" tags...I already have a css and jquery solution to do the styling. My problem comes from pulling the data out of the database and using a recursive function via PHP to build the list ... the list is a concatenated string that gets parsed to build the tree. I'm really having a hard time getting the closing "ul" and "li" tags to line up just where they need to be. Is this the best way to do this? Are there other better ways using arrays or something like that to do this? Any examples you can point me to of "best practices" for building a list like this will be appreciated. Thanks.

• Can Nokogiri use a SAX parser to parse an HTML fragment?

  - by .yahoo.co.jpaqwsykcj3aulh3h1k0cy6nzs3isj

  I have this code. class MyParser < Nokogiri::XML::SAX::Document def characters(string) LOG.debug("characters #{string}") end def start_element(name, attrs = []) LOG.debug("start_element #{name}") end def end_element(name) LOG.debug("end_element #{name}") end end parser = Nokogiri::HTML::SAX::Parser.new(MyParser.new) parser.parse(File.new($*[0], 'rb')) Run on an HTML fragment like this, <h1>Hello</h1> <p>Hi.</p> the output shows that only the first element is processed: start_element h1 characters Hello end_element h1 If I wrap the fragment in html and body tags, the whole input is parsed. Is there a way to use a SAX style parser on HTML fragments?

• Data validate tools (ETL tools) for SQL server

  - by Stan

  I have some data in Excel and need to import into database. Is there any tool that can validate and maybe clean the data? Does Red Gate have such tool? The input will be Excel. Given table constraints, eg. CHECK, UNIQUE KEY, datetime format, NOT NULL. Desire output should be as least shows which lines are having problems, and then fix some trivial error automatically, like fill in default value for NULL columns, automatically correct datetime format. I know using Python can build such a script. But just wonder what's the popular way to do this. Thanks.

• Why Java SimpleDateFormat().parse() is printing weird formate?

  - by MAK

  My input is String formated as the following: 3/4/2010 10:40:01 AM 3/4/2010 10:38:31 AM My code is: DateFormat dateFormat = new SimpleDateFormat("dd/mm/yyyy hh:mm:ss aa"); try { Date today = dateFormat.parse(time); System.out.println("Date Time : " + today); } catch (ParseException e) { e.printStackTrace(); } the output is: Sun Jan 03 10:38:31 AST 2010 Sun Jan 03 10:40:01 AST 2010 I'm not sure from where the day (Sun) came from? or (AST)? and why the date is wrong? I just wanted to keep the same format of the original String date and make it into a Date object. I'm using Netbeans 6.8 Mac version.

• WAMP not sending file headers (content-type) correctly

  - by Industrial

  Hi! I cant get a PHP file to send correct headers at my WAMP server. Wouldn't be a problem normally except that is phpMyAdmin that is freaking out right now. Here's the row that the file that merges the css files together in phpmyadmin uses to send the output as CSS. header('Content-Type: text/css; charset=UTF-8'); I have also putted a .htaccess file in the phpmyadmin directory: AddType text/css .css Neither is working. What can I do to make sure that this file is interpreted as a CSS by firefox?

• Why does PowerShell fail to build my .net solutions? ("file is being used by another process")

  - by urig

  I've written a PowerShell script to build several .net solutions one after the other. It simply makes several calls to csc.exe to build the .sln files. Almost every time I run the script one of the solutions fails to build and CSC.exe reports: error CS1606: Assembly signing failed; output may not be signed -- The process cannot access the file because it is being used by another process. This happens even though I've closed all instances of Visual Studio holding these solutions and I've none of their exes running on mu machine. A similar batch file that I've written works just fine. It's only PowerShell that complains about the file being used by another process. How can avoid having this happen? Are there any better examples out there of building .net solutions through PowerShell?

• Are there any serialization frameworks for java

  - by Grofit

  I know there is simple, which seems to be a decent enough XML serializer and i know there is Jaxb which seems to do the job as well. However im after something a bit more generic, so I could serialize my model to Xml, Json, Binary etc. So the models are just dumb objects that just get thrown into some sort of serialization factory and then the relevant output is spat out... I dont see any reason why you couldn't do this with reflection, so for a REALLY simple solution get the relevent public properties, cut off the get or set and make that the element name... i.e getPersonName() would become <PersonName>xxxx</PersonName> or PersonName:XXXXX

• Batch scripting for directories or better method

  - by baron

  Hi Everyone, Looking at creating a simple batch file for my app. My app needs some directories to be in place as it runs. The first method I thought was just make a batch script: @ECHO OFF IF NOT EXIST C:\App GOTO :CREATE ELSE GOTO :DONTCREATE :CREATE MKDIR C:\App\Code ECHO DIRECTORY CREATED :DONTCREATE ECHO IT WAS ALREADY THERE 1) This doesn't run as I would expect. Both :CREATE and :DONTCREATE seem to run regardless? How do I do an If properly then? Output: A subdirectory or file C:\App\Code already exists. DIRECTORY CREATED IT WAS ALREADY THERE So it enters both true and false statements? 2) The app is a C# WPF app. For what I am trying to do here (create a couple of directories if they don't already exist) - should I do it some other way? Perhaps in the application as it runs?

• MVC 2 Conversion Disrupts the parameters passed to my Stored Procedure

  - by user54197

  I have a few textboxes that are not required. If the user enters nothing it is passed as 'null' in MVC 2. It was passed as '""' in MVC 1. What changes can I make to accomodate for this? public string Name { get; set; } public string Offer{ get; set; } public string AutoID { get; set; } using (SqlConnection connect = new SqlConnection(connections)) { SqlCommand command = new SqlCommand("Info_Add", connect); command.Parameters.Add("autoID", SqlDbType.BigInt).Direction = ParameterDirection.Output; command.Parameters.Add(new SqlParameter("name", Name)); //Offer now returns a null value, which cannot be passed command.Parameters.Add(new SqlParameter("offer", Offer)); command.CommandType = CommandType.StoredProcedure; connect.Open(); command.ExecuteNonQuery(); AutoID = command.Parameters["autoID"].Value.ToString(); }

• Trying to find a match in two strings - Python

  - by Jacob Mammoliti

  I have a user inputting two strings and then I want to check if there are any similar characters and if there is, get the position where the first similarity occurs, without using the find or index function. Below is what I have so far but I doesn't fully work. With what I have so far, I'm able to find the similarities but Im not sure how to find the position of those similarities without using the index function. string_a = "python" string_b = "honbe" same = [] a_len = len(string_a) b_len = len(string_b) for a in string_a: for b in string_b: if a == b: same.append(b) print (same) Right now the output is: ['h', 'o', 'n'] So basically what I am asking is, how can I find the position of those characters without using the Python Index function?

• Manipulating multi-track ogg files programatically

  - by Chad Birch

  I'm planning to create a program for manipulating multi-track OGG files, but I don't have any experience with the relevant libraries, so I'm looking for recommendations about which language/library to use for this. I don't really have any preference for the language, I'll happily code it in C, C#, Python, whatever makes things the easiest (or even possible). Perhaps it's even a possibility to automate Audacity somehow? In terms of requirements, I'm not looking for anything particularly fancy. It will probably be a command-line program, I don't need to be able to play the audio, draw image representations of the waveforms, etc. The program will basically be used as a converter, but I need to do some processing before outputting. That is, I need the ability to programatically remove some tracks, set panning per-track, change track volumes, etc. Nothing too complex, just some basic processing, and then output the result in either MP3 or a format easily converted to MP3, such as WAV. Any suggestions or general information would be appreciated, thanks.

• How to capture shift-tab in vim

  - by Yogesh Arora

  I want to use shift-tab for auto completion and shifting code blocks visually. I have been referring to Make_Shift-Tab_work . That link talks about mapping ^[[Z to shift-tab . But i don't get ^[[Z when i press shift-tab. i just get a normal tab in that case. It then talks about using xmodmap -pke | grep 'Tab' to map tab keys. According to that the output should be keycode 23 = Tab or keycode 23 = Tab ISO_Left_Tab However i get keycode 22 = Tab KP_Tab if i use xmodmap -e 'keycode 22 = Tab ISO_Left_Tab' and after that xmodmap -pke | grep 'Tab', I still get keycode 22 = Tab KP_Tab This means running xmodmap -e 'keycode 22 = Tab ISO_Left_Tab' has no effect. In the end the link mentions using xev to see what X recieves when i press shift-tab. But i dont have xev on my system. Is there any other way i can capture shift-tab in vim

• Selection of parameters in Diffie-Hellman

  - by allenzzzxd

  Hello, maybe it's not so proper to ask this question here... anyway, I'm trying to use the gmp library for the implementation of DH, but the problem here I got is: Once, when I was doing the tests to observe the output, although big values of prime and the private keys were selected: p was about more than 300 digits long in decimal a, b were about 100 digits long finally I got a shared secret key which was extremely small, perhaps smaller than 10^8 in decimal... This problem didn't show up many times, in fact, during all the observation, it appeared just once...but still, this was not so good at all. So I wonder if there are some methods which can avoid this... Thanx a lot

• How to retrieve a binary file from .NET assembly?

  - by Rahul Soni

  I have an excel file that I want to embed in my C# assembly. I have changed the build action of the XLSX file to "Embedded Resource". During runtime, I have to retrieve this XLSX file from the assembly. Assembly assembly = Assembly.GetExecutingAssembly(); StreamReader sr = new StreamReader(assembly.GetManifestResourceStream("AssemblyName.Output.xlsx"), true); StreamWriter sw = new StreamWriter(strPath); sw.Write(sr.ReadToEnd()); sr.Dispose(); sw.Dispose(); System.Diagnostics.Process.Start(strPath); As expected, this fails for the XLSX file since it is a binary data. This could works well with a text file. I tried binary read/write, but I am not able to get the code running. Thoughts?
