• Redirect packages directed to port 5000 to another port

  - by tdc

  I'm trying to use eboard to connect to the FICS servers (http://www.freechess.org), but it fails because port 5000 is blocked (company firewall). However, I can connect to the server through the telnet port (23): telnet freechess.org 23 (succeeds) telnet freechess.org 5000 (fails) Unfortunately the port number is hardcoded (see here: http://ubuntuforums.org/archive/index.php/t-1613075.html). I'd rather not have to hack the source code as the author of that thread ended up doing. Can I just forward the port on my local machine using iptables? I tried: sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 5000 -j REDIRECT --to-port 23 and sudo iptables -t nat -I OUTPUT --src 0/0 -p tcp --dport 5000 -j REDIRECT --to-ports 23 but these didn't work... Note that: $ sudo iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere anywhere tcp dpt:5000 redir ports 23 Chain POSTROUTING (policy ACCEPT) target prot opt source destination

• I want to try and find an RFC for Business Listings.

  - by nc01

  I'm trying to figure out how to find out if there's a good standard format for sharing business information such as: Business Name Address - well-defined fields Lat,Lng Coords Business Type - maybe from a well-defined enum, my starting point contains Retail,Food,Drink,Coffee,Service Hours of operation - including a spot for 'except laksdasd' or 'sometimes we open late' which could be just plain language Business Keywords - don't know if this is asking too much. how well do http meta tags work in practice? So, if no such thing exists, is this something I can submit to IETF? I can't currently find it on http://www.rfc-editor.org/cgi-bin/rfcsearch.pl , and vCard doesn't suit my needs.. Thanks!

• Moved sitemaps to a different subdomain and losing search referrals around the same time. Red herring or correlation?

  - by er1234

  We started to lose search referral traffic around the same time that I moved some of our sitemaps to a subdomain. Could this have hurt us? I followed Google's steps to creating a sitemap under a different subdomain. The new sitemaps.foo.com subdomain is being crawled and indexed well. Both www.foo.com and sitemaps.foo.com have been verified in Google Webmaster Tools. They appear as distinct sites. Is this correct? I can't find a way in Webmaster Tools to say "Hey, sitemaps.foo.com is really owned by www.foo.com, so show them together and make sure to attribute sitemaps.foo urls to www.foo" Our www.foo.com/robots.txt Sitemap: http://www.foo.com/sitemap.xml Sitemap: http://sitemaps.foo.com/subdir/sitemap.xml.gz

• VirtualBox Port Forward

  - by john.graves(at)oracle.com

  A great new feature in VirtualBox 4.0 is the ability to use NAT networking and forward ports without needing to use ssh -L/-R tricks.  This is great for booting multiple VM domains simultaneously.  It is possible to have several instances which map back to the host machine and different ports on localhost:* automatically forward to the correct VM.  This avoids the hassle of setting up dns entries or static IP addresses.In this example, I'm mapping the host ports 3xxxx to the VM's well known server ports.Note: It is important to setup the Frontend HTTP host/port to avoid incorrect URL rewriting.You may also need to setup an http channel to deal with local traffic which uses the network address 10.0.2.15Happy VMing.

• Warning about unavailable repositories

  - by richzilla

  An icon has recently appeared on my panel with an exclamation mark. The message i get when hovering over this is that the update information is out of date, and that this may be caused by an unavailable repository or a network isssue.

• Should I Learn C/C++ Even If I Just Want To Do Web Programming?

  - by Daniel

  My goal is to be able to create online apps and dynamic, database driven websites. For instance, if in the future I get the idea for the next Digg or Facebook, I want to be able to code it myself. To arrive there I think I have basically two paths: Path 1 Start at a basic level, learning C, then C++ for OOP, then algorithms and data structures, with the goal of getting a solid grasp of computer programming. Only then move to PHP/MySQL/HTTP and start working on practical programming projects. Path 2 Start directly with PHP/MySQL/HTTP and getting my hands dirty with practical projects right away. What would you guys recommend?

• Convert Currencies Dynamically using PHP, Google and cURL [closed]

  - by LizO

  I want to be able to allow users to dynamically change the currency of the products prices in my webstore, right there on the page. For example, 300 USD will change to 221.61 EUR when the user selects Euros from a dropdown. I found a few sites with PHP code for a calculator/input format (user inputs value and converted currency is output.) http://www.chazzuka.com/blog/?p=104 http://www.pixel2life.com/publish/tutorials/1166/currency_conversion_in_php/page-3/ I was hoping someone could help me figure out how to modify the PHP script. Thanks in advance.

• Avoid penalties for duplicate (multilanguage) shared hosting

  - by Dave

  My concern is about SEO. Now let me explain the scenario. I am making a 3 languages website. The development is alright, but I was targeting local customers with one domain, and international (english version) with another. Eg: Local http://www.minhalojadesapatos.com.br (this is not the real website, just example!) Other http://www.myshoesstore.com.br Both domain point to exactly the same hosting and content, but when user comes through local domain, default language is set to portuguese, otherwise, default is english. Language handling on backend uses PHP Sessions and cookies, so with just a click users can change content language. How to avoid being SEO-penalised in this context? (yeah, I was hungry when focusing market for choosing two domains but the activity really needs that, it is a travel agency).

• is it ok to have 2 sitemaps on 1 website?

  - by user615041

  Do I have to have a sitemap page on my index page for bots to read it or can I just have it anywhere on my server? I have a phpbb/wordpress integration and I need 2 sitemaps mods for each one (or I need to have them somehow integrated together into one xml sitemap). Is this possible? Whats my best option? I would have the phpbb one something like this: http://www.example.com/phpbb/sitemap.html and the wordpress one something like this: http://www.example.com/wordpress/sitemap.html and then I would submit both off..but not have the links on my footer to confuse anyone.., the sitemaps would strictly be for search engines. Is this a good idea? what are you thoughts?

• Removing surrounding noises from voice recording

  - by Peak Reconstruction Wavelength

  I have a wave file whose frequency spectrum looks like this. http://i.stack.imgur.com/2rRaS.png It contains audio, which I want to keep while removing the rest. The problem is that the surround noise changes, just those distinct voice patterns remain. I marked the voice patterns for clarity: http://i.stack.imgur.com/eLkBl.png What could an algorithm look like / a workflow in adobe audition look like that removes everything but the voice patterns? I think that the main characteristic is the line-shaped form over time. Loudness alone is not enough as the noise is loud aswell.

• Is it possible to track redirects to external sites from our subdomains?

  - by ChaBuku

  I have a handful of subdomains set up as redirects because we are using them for QR codes. I want to be able to track the QR code redirects (which are already set up and printed so no changing them at this point) and see the effectiveness of each. Here's two examples: http://qr.glorkianwarrior.com and http://ad.glorkianwarrior.com are set up to forward to our iTunes page (later on this year it may forward to Google Play or a specific landing page), is there any way on my server to track the redirect from the subdomain to iTunes and see where traffic is coming from first? I have the redirects set up through cPanel presently using subdomains. Edit: From the research I've seen I can't track a 301 directly. If I redirect to an internal page and then do a timed redirect to the iTunes link, how long will it take for the tracking script to track a hit?

• Using todolist (abstract spoon) on ubuntu 11.10?

  - by Tal Galili

  I wish to run todolist 6.3.8 (http://www.codeproject.com/KB/applications/todolist2.aspx) on ubuntu 11.10. I have installed the latest wine and winetricks. I have tried running: http://www.codeproject.com/KB/applications/todolist2.aspx winetricks vcrun2005 winetricks vcrun2008 winetricks vcrun6 Which installed all of the components. When I went to run todolist.exe, it started fine with the "first time wizard" (asking me where to save definitions and what file to open first), and then it stopped saying "the program todolist.exe has encountered a serious problem and needs to close. we are sorry for the inconvenience". What can I do to make this (great) software work on ubuntu? Thanks.

• mod_rewrite for clean URL doesn't work

  Basically what I want to do is to convert this: http://localhost/jariungu/user_caleg.php?idCaleg2014=3 into this: http://localhost/jariungu/caleg/3 I have managed to make /jariungu/caleg/3 to direct to the original URL (as in, if I open that URL, it directs me to the appropriate page). The problem is, once opened, the URL returns to the original, ugly one in the address bar. This is what I tried. Could someone provide a help? <IfModule mod_rewrite.c> Options +FollowSymlinks RewriteEngine On RewriteBase /jariungu/ RewriteRule ^caleg\/([0-9]+)\/([a-zA-Z]+\s*[0-9]*)/?$ caleg.php?idCaleg2014=$1&namaCaleg=$2 [NC,L] RewriteRule ^caleg\/([0-9]+)/?$ caleg.php?idCaleg2014=$1 [NC,L] </IfModule>

• .htaccess 301 Redirect for wildcard subdomains

  - by Steve

  I run Wordpress in Network mode, which means I can have multiple websites running off one installation of Wordpress. Each website runs as a subdomain. Wordpress handles this using .htaccess, and a wildcard subdomain pointing to the location of Wordpress, so there are no actual subdomains created in cPanel; just a wildcard subdomain in cPanel, ad Wordpress handles the rest. I want to 301 redirect http://one.example.com/portfolio to http://two.example.com/portfolio. If I only have 1 .htaccess file in the web root of example.com, how do I achieve this?

• Another Linq to SQL product, Enzo Multitenant Framework

  - by Ed Gnatiuk

  An open source library and full product have been developed for transparently splitting large tables across several databases for performance, similar to database table partitioning.  It is all handled along with the Linq to SQL framework, and looks pretty slick, I will be reviewing the product shortly.  It looks mostly transparent to the developer!  There are other capabilites worth a look.  This looks like it works for azure as well. Here are some links:  http://enzosqlshard.codeplex.com/   http://enzosqlbaseline.com    https://scale.bluesyntax.net   I will be reviewing this and other Linq to SQL libraries soon.
