  • Why is /usr/bin/env permission denied to rails server?

    - by Eric Hopkins
    I've just set up rails on an apache server running on Ubuntu, and when I try to go to the root page it gives this error: /usr/bin/env: bash: Permission denied env and all the directories in the path all have permissions 755. I tried setting env to have permissions 777 but still got the same error. Rails is running as "nobody". Why is this happening? I don't know what else to try. In /etc/apache2/sites-available/api.conf: <VirtualHost *:80> ServerName api.thinknation.ca ServerAlias api.thinknation.ca DocumentRoot /var/www/api/public ErrorLog /var/www/logs/error.log CustomLog /var/www/logs/access.log combined RailsSpawnMethod smart <Directory /var/www/api/public> # This relaxes Apache security settings.

  • How make rewrite rules relative to .htaccess file.

    - by Kendall Hopkins
    Current I have an .htaccess file like this. RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f [OR] RewriteCond %{REQUEST_URI} ^/(always|rewrite|these|dirs)/ [NC] RewriteRule ^(.*)$ router.php [L,QSA] It works create when the site files are in the document_root of the webserver (ie. domain.com/abc.php - /abc.php). But in our current setup (which isn't changeable), this isn't ensured. We can sometimes have arbitrary folder in between the document root and folder of the .htaccess file (ie. domain.com/something/abc.php - /something/abc.php). The only problem with is that is the second RewriteCond no longer works. Is there anyway to dynamically check if the accessed path by a path relative to .htaccess file. For Example: If I have a site where domain.com/rewrite/ is the directory of the .htaccess file. NOT FORCED TO REWRITE -> domain.com/rewrite/index.php FORCED TO REWRITE -> domain.com/rewrite/rewrite/index.php If I have a site where domain.com/ is the directory of the .htaccess file. NOT FORCED TO REWRITE -> domain.com/index.php FORCED TO REWRITE -> domain.com/rewrite/index.php

  • On Mac OS X how can I monitor what is using my internet connection?

    - by Jon Hopkins
    I've got a relatively limited broadband connection (I live miles from the nearest exchange) and from time to time net access (but nothing else) slows to a near crawl. I know from a bit of monitoring software that the connection is being fairly heavily used which would explain it but I don't know what's using it. There are certainly plenty of things which might (these days there are dozens of apps that will either regularly or infrequently check data or download updates) but how can I find out? I'm happy to pay (a small amount of) money if needed, though in that case I'd rather it were a recommendation that me just Googling for something.

  • Social Technology and the Potential for Organic Business Networks

    - by Michael Snow
    Guest Blog Post by:  Michael Fauscette, IDCThere has been a lot of discussion around the topic of social business, or social enterprise, over the last few years. The concept of applying emerging technologies from the social Web, combined with changes in processes and culture, has the potential to provide benefits across the enterprise over a wide range of operations impacting employees, customers, partners and suppliers. Companies are using social tools to build out enterprise social networks that provide, among other things, a people-centric collaborative and knowledge sharing work environment which over time can breakdown organizational silos. On the outside of the business, social technology is adding new ways to support customers, market to prospects and customers, and even support the sales process. We’re also seeing new ways of connecting partners to the business that increases collaboration and innovation. All of the new "connectivity" is, I think, leading businesses to a business model built around the concept of the network or ecosystem instead of the old "stand-by-yourself" approach. So, if you think about businesses as networks in the context of all of the other technical and cultural change factors that we're seeing in the new information economy, you can start to see that there’s a lot of potential for co-innovation and collaboration that was very difficult to arrange before. This networked business model, or what I've started to call “organic business networks,” is the business model of the information economy.The word “organic” could be confusing, but when I use it in this context, I’m thinking it has similar traits to organic computing. Organic computing is a computing system that is self-optimizing, self-healing, self-configuring, and self-protecting. More broadly, organic models are generally patterns and methods found in living systems used as a metaphor for non-living systems.Applying an organic model, organic business networks are networks that represent the interconnectedness of the emerging information business environment. Organic business networks connect people, data/information, content, and IT systems in a flexible, self-optimizing, self-healing, self-configuring, and self-protecting system. People are the primary nodes of the network, but the other nodes — data, content, and applications/systems — are no less important.A business built around the organic business network business model would incorporate the characteristics of a social business, but go beyond the basics—i.e., use social business as the operational paradigm, but also use organic business networks as the mode of operating the business. The two concepts complement each other: social business is the “what,” and the organic business network is the “how.”An organic business network lets the business work go outside of traditional organizational boundaries and become the continuously adapting implementation of an optimized business strategy. Value creation can move to the optimal point in the network, depending on strategic influencers such as the economy, market dynamics, customer behavior, prospect behavior, partner behavior and needs, supply-chain dynamics, predictive business outcomes, etc.An organic business network driven company is the antithesis of a hierarchical, rigid, reactive, process-constrained, and siloed organization. Instead, the business can adapt to changing conditions, leverage assets effectively, and thrive in a hyper-connected, global competitive, information-driven environment.To hear more on this topic – I’ll be presenting in the next webcast of the Oracle Social Business Thought Leader Webcast Series - “Organic Business Networks: Doing Business in a Hyper-Connected World” this coming Thursday, June 21, 2012, 10:00 AM PDT – Register here

  • Getting mysql row that doesn't conflict with another row

    - by user939951
    I have two tables that link together through an id one is "submit_moderate" and one is "submit_post" The "submit_moderate" table looks like this id moderated_by post 1 James 60 2 Alice 32 3 Tim 18 4 Michael 60 Im using a simple query to get data from the "submit_post" table according to the "submit_moderate" table. $get_posts = mysql_query("SELECT * FROM submit_moderate WHERE moderated_by!='$user'"); $user is the person who is signed in. Now my problem is when I run this query, with the user 'Michael' it will retrieve this 1 James 60 2 Alice 32 3 Tim 18 Now technically this is correct however I don't want to retrieve the first row because 60 is associated with Michael as well as James. Basically I don't want to retrieve that value '60'. I know why this is happening however I can't figure out how to do this. I appreciate any hints or advice I can get.

    - by Michael Mao

  • What do you use to loadbalance IPv6 services?

    - by Michael Renner
    Hi, the current Linux software environment for IPv6 load balancing looks a bit grim. IPVS has rudimentary support for IPv6 but it's far from complete. NAT for IPv6 seems to be a no-go. Are there any other projects which aim for this goal? Does the IPv6 support in other OS look better? Are there any commercial products which have been successfully used in production environments with non-trivial load patterns? Or is it just that the time for IPv6 hasn't come... yet? ;) best regards, Michael

  • Windows 7 Locking up Randomly

    - by Michael Moore
    I've got a Windows 7 machine that is locking up randomly. It can be in the first thirty seconds, or it can be hours later. There is nothing specific I can find that is running when it happens. When it locks, the screen doesn't change, but nothing moves. The waiting icon stops, the mouse stops, keyboard doesn't work, etc. I've even tried the crash on ctrl-scrl registry hack, and it won't even dump the kernel. I've run hardware diagnostics on the RAM and it doesn't find any problems. I would think it is a hardware issue, but on this exact same machine, I can run 64 Bit Ubuntu and it has zero problems. I've even tried reinstalling Windows7 from scratch, and it still happens. Anyone have any ideas? Any good diagnostic tools to recommend? Thanks! Michael

  • Secure copy in Linux

    - by Michael
    Hi all, I wanna simpy exchange 3 directories to a collegue's home directory (I dont have write access to that one) from my home directory, probably using secure copy if possible. I am not good with Linux command line, so I am not sure how to do that and I would very much appreciate it if somebody could help me a bit out with this. I guess it should look something like that scp -r /home/user1/directoy1 /home/user2/directoy1 scp -r /home/user1/directoy2 /home/user2/directoy2 scp -r /home/user1/directoy3 /home/user2/directoy3 Do I need to specify the login name of my collegue so that the files can be copied when he enters his password? Thanks for your help, Michael

  • USB Flash drive corrupt files - Help needed

    - by Michael
    I have a 16gb usb flash drive with 8gb worth of data that I can't afford to lose. When I inserted it into my pc, inside the folder that I was storing the data I saw unintelligible characters and nothing in there would open. I ran, windows scandisk and the files (unfortunately) disappeared. I can see that the drive's space still appears to be taken up with data, about 8gb. What should I do to recover it? Is it possible? Thanks in advance... Michael

  • Virtual hosting in Varnish with individual vcl files for configuration

    - by Michael Sørensen
    I wish to use varnish to put in front of an apache and a tomcat on the same server. Depending on the ip requested, it goes to a different backend. This works. Now for most of the sites the default varnish logic will work just fine. However for some specific sites I wish to use custom VCL code. I can test for host name and include config files for the specific domains, but this only works inside the individual methods recv etc. Is there a way to include a complete set of instructions, in one file, per domain, without having to manage separate files for subdomain_recv, subdomain_fetch etc? And preferably without running seperate instances of varnish. When I try to include a file on the "root level" of default.vcl, I get a compilation error. Best regards, Michael

  • jQuery jFlow plugin. How can I have more than one on a single page?

    - by Michael
    Hi, I'm using a very lovely and simple plugin called jFlow that gives me a basic content slider etc. However, I can see no documentation or help on how to get two (or more) on one page at the same time working seperately from one another. At the moment, if I set two up, they almost combine as one, despite having a different configuration from one another. Any help would be great, thanks. Michael.
