  • fopen() fails to open stream: permission denied, yet permissions should be valid

    - by about blank
    So, I have this error: Warning: fopen(/path/to/test-in.txt) [function.fopen]: failed to open stream: Permission denied Performing ls -l in the directory where test-in.txt is produces the following output: -rw-r--r-- 1 $USER $USER 1921 Sep 6 20:09 test-in.txt -rw-r--r-- 1 $USER $USER 0 Sep 6 20:08 test-out.txt In order to get past this, I decided to perform the following: chgrp -R www-data /path/to/php/webroot And then did: chmod g+rw /path/to/php/webroot Yet, I still get this error when I run my php5 script to open the file. Why is this happening? I've tried this using LAMP as well as cherokee through CGI, so it can't be this. Is there a solution of some sort? Edit I'll also add that I'm just developing via localhost right now. Update - PHP fopen() line $fullpath = $this->fileRoot . $this->fileInData['fileName']; $file_ptr = fopen( $fullpath, 'r+' ); I should also mention I'd like to stick with Cherokee if possible. What's this deal about setting file permissions for Apache/Cherokee?

  • Is this valid Java code?

    - by Eric
    I'm using Eclipse, and it is perfectly happy with the following code: public interface MessageType { public static final byte KICK = 0x01; public static final byte US_PING = 0x02; public static final byte GOAL_POS = 0x04; public static final byte SHUTDOWN = 0x08; public static final byte[] MESSAGES = new byte[] { KICK, US_PING, GOAL_POS, SHUTDOWN }; } public class MessageTest implements MessageType { public static void main(String[] args) { int b = MessageType.MESSAGES.length; //Not happy } } However, the platform that I'm running it on crashes at the line marked above. By crash, think an equivalent of a BSOD. Is there anything wrong with my code, or do I need to pursue the developers of the Java VM for my platform?

  • VB.NET Use WebRequest to check if URI is valid

    - by Robbo
    Looking for the best way to determine if a URI exists in VB.NET without downloading the actual content. System.IO.FileExists/My.Computer.FileSystem.FileExists can be used locally to determine if a file exists, is there an equivalent for the Web? Currently I am using a HttpWebRequest to check URI existance using the ResponseStream. This populates the stream if the target does exist and throws an exception if it doesn't. The function is being expanded to also check for PDF files (typically 5MB +), images, etc and it will be a waste of time/bandwidth to actually populate the content into a stream. In the case of "Success" (the target does exist) I do not wish to download the file or page, simply to end up with a Boolean which indicates the whether something exists at the end of this URI.

  • Is CDS a valid analogy for pointers? [closed]

    - by Flinkman
    So.. bear with me. I just found an analogy to c++ pointers and CDS. This clip describes CDS(Credit Default Swaps). http://www.youtube.com/watch?v=KPNdYtrlgaU#t=120s "Here we know we have an instrument of a particular financial instrument that is demonstrably dangerous, it creates long chains of risk which are vulnerable to the failure of individual trader or market partipants, in that chain and these instruments in an affect permit the creation of vicious spirals. In which the CDS price interact with the bound price, the market price and you can have a downward spiral." What my ears are telling me: "Don't create dependences that will create long chains of crashing systems." Update: Trying to clarify with something that is closer to the readers. If I change the words: instrument = construct financial = language trader = object market partipants = c structs CDS price = uptime bound price = outcome market price = ROI(return on incestment) The quote become more understandable. Look: "Here we know we have construct of a particular language construct that is demonstrably dangerous, it creates long chains of risk which are vulnerable to the failure of individual object or structs in that chain and these system in an affect permit the creation of vicious spirals. In which the uptime interact with the outcome, the ROI and you can have a downward spiral."

  • Rails 3 MySQL 2 reports an error in what looks to be valid SQL syntax

    - by John Judd
    I am trying to use the following bit of code to help in seeding my database. I need to add data continually over development and do not want to have to completely reseed data every time I add something new to the seeds.rb file. So I added the following function to insert the data if it doesn't already exist. def AddSetting(group, name, value, desc) Admin::Setting.create({group: group, name: name, value: value, description: desc}) unless Admin::Setting.find_by_sql("SELECT * FROM admin_settings WHERE group = '#{group}' AND name = '#{name}';").exists? end AddSetting('google', 'analytics_id', '', 'The ID of your Google Analytics account.') AddSetting('general', 'page_title', '', '') AddSetting('general', 'tag_line', '', '') This function is included in the db/seeds.rb file. Is this the right way to do this? However I am getting the following error when I try to run it through rake. rake aborted! Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'group = 'google' AND name = 'analytics_id'' at line 1: SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; Tasks: TOP => db:seed (See full trace by running task with --trace) Process finished with exit code 1 What is confusing me is that I am generating correct SQL as far as I can tell. In fact my code generates the SQL and I pass that to the find_by_sql function for the model, Rails itself can't be changing the SQL, or is it? SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; I've written a lot of SQL over the years and I've looked through similar questions here. Maybe I've missed something, but I cannot see it.

    UPDATE polls_options SET `votes`=`votes`+1, `percent`=ROUND((`votes`+1) / (SELECT voters FROM polls WHERE poll_id=? LIMIT 1) * 100,1) WHERE option_id=? AND poll_id=? Don't have table data yet, to test it properly. :) And by the way, in what type % integers should be stored in database? Thanks for the help!

  • fast forward/streaming in html5 video? RTSP?

    - by karpodiem
    right now I've got a few .mp4's hosted on Amazon S3. I know that S3 has support for RTMP, which is useful for streaming Flash. I'd like to accomplish something similar with html5 video; my biggest issue is that I need the ability to seek (fast forward) to a particular part of the video. Right now when I query the video, it loads the entire video before playing, which is a waste of bandwidth/dealbreaker. In what manner could this be implemented? Is this even possible? Looks like RTSP would be a good bet, but I haven't found whether anyone has rolled this out successfully.

  • Display HTML in an Actionscript 3 project

    - by Marcus Blankenship
    Folks, I am pulling all my Flash (pure AS3 project, not Flash CS3) content from a Drupal back-end for SEO purposes. This works great, except the HTML rendering built into the TextField object leaves a lot to be desired. Could anyone recommend any libraries that would allow me to display HTML elements? At this stage, commercial or open-source libraries are welcome. Thanks, Marcus
