  • Duplicating someone's content legitimately & writing HTML to support that

    - by Codecraft
    I want to add content from other blogs to my own (with the authors permission) to help build additional relevant content and support articles I've found useful that others have written. I'm looking into how to do this responsibly - ie, by giving the original content author a boost and not competing against them for search traffic which should go to their site. In order to keep my duplicate content out of search, and to hint to the search engines where the original content is to be found i've implemented: <head> <meta name='robots' content='noindex, follow'> <link rel='canonical' href='http://www.originalblog.com/original-post.html' /> </head> Additionally, to boost the original article and to let readers know where it came from i'll be adding something like this: <div> Article originally written by <a href='http://www.authorswebsite.com'>Authors Name</a> and reproduced with permission.<br/> <a href='http://www.originalblog.com/original-post.html' target='new'> Read the original article here. </a> </div> All that remains is a way to 'officially' credit the original author in the HTML for the search spiders to see. Can anyone tell me a way to do this possibly using rel="author" (as far as I can see thats only good for my own original content), or perhaps it doesn't matter given that the reproduced pages will be kept out of search engines? Also, have I overlooked anything in the approach?

  • Representing and executing simple rules - framework or custom?

    - by qtips
    I am creating a system where users will be able to subscribe to events, and get notified when the event has occured. Example of events can be phone call durations and costs, phone data traffic notations, and even stock rate changes. Example of events: customer 13532 completed a call with duration 11:45 min and cost $0.4 stock rate for Google decreased with 0.01% Customers can subscribe to events using some simple rules e.g. When stock rate of Google decreases more than 0.5% When the cost of a call of my subscription is over $1 Now, as the set of different rules is currently predefined, I can easily create a custom implemention that applies rules to an event. But if the set of rules could be much larger, and if we also allow for custom rules (e.g. when stock rate of Google decreses more than 0.5% AND stock rate of Apple increases with 0.5%), the system should be able to adapt. I am therefore thinking of a system that can interpret rules using a simple grammer and then apply them. After som research I found that there exists rule-based engines that can be used, but I am unsure as they seem too complicated and may be a little overkill for my situation. Is there a Java framework suited for this area? Should we use framework, a rule engine, or should we create something custom? What are the pros and cons?

  • Websockets through Stunnel is giving random bytes.

    - by user16682
    I have several servers set up for a web application that I am developing. One is a load balancing server, and I'm running a php WebSockets server on this balancer. The website that I am developing on uses ssl, so I have my WebSockets running through a wss uri connecting directly to the balancer, where I have set up stunnel4 to decrypt all traffic at a certain port and re-rout it to my php WebSockets server. This works fine when it comes down to connecting to my server. That's not the problem. The problem occurs when I try to send data to the server. Occasionally when I try this, stunnel does not appear to be decrypting the data properly. I get garbage characters in my termanal running the server: what appear to be completely random bytes. This can sometimes go on for several consecutive messages that I send before abruptly working again. It is very erratic and unpredictable. Sometimes I refresh the page, and all the messages work perfectly. Sometimes the WebSocket connects and I have to wait 5-10 seconds before any messages I send are interpreted properly by the server. Other times I can't send any messages at all, because they all end up as garbage. I believe this is a stunnel problem, but I am not certain. Does anybody have any experience with this? I would like a more predictable server if I can get it. Some more information: This occurs extensively in Chrome, not quite as much in FireFox, and never in Safari. The php server I am using is phpws http://code.google.com/p/phpws/ -- On the WebSocket connection, this server would sometimes detect that the header was only 1 byte in size, the first byte of the WebSockets header. I had to modify the server to flush the buffer ever time this occurred so that it would reliably connect.

  • Sun2Oracle: Upgrading from DSEE to the next generation Oracle Unified Directory - webcast follow up

    - by Darin Pendergraft
    Thanks to all of the guest speakers on our Sun2Oracle webcast: Steve from Hub City Media, Albert from UCLA and our own Scott Bonell. During the webcast, we tried to answer as many questions as we could, but there were a few that we needed a bit more time to answer.  Albert from UCLA sent me the following information: Alternate Directory EvaluationWe were happy with Sun DSEE. OUD, based on the research we had done, was a logical continuation of DSEE.  If we moved away, it was to to go open source. UCLA evaluated OpenLDAP, OpenDS, Red Hat's 389 Directory. We also briefly entertained Active Directory. Ultimately, we decided to stay with OUD for the Enterprise Directory, and adopt OpenLDAP for the non-critical edge directories.HardwareFor Enterprise Directory, UCLA runs 3 Dell PowerEdge R710 servers. Each server has 12GB RAM and 2 2.4GHz Intel Xeon E5 645 processors. We run 2 of those servers at UCLA's Data Center in a semi active-passive configuration. The 3rd server is located at UCLA Berkeley. All three are multi master replicated. At run time, the bulk of LDAP query requests go to 1 server. Essentially, all of our authn/authz traffic is being handled by 1 server, with the other 2 acting as redundant back ups.

  • Adding a CMS to an existing Magento shop

    - by user6341
    I am working on a project for 3 niche stores built on magento (using magento's multi-store function) that each get roughly 50k unique visitors a day. The sites don't currently have a blog or forum or any social networking aspects. Would like to add a cms to each site that can be centrally run and would like it to take over the front end content from Magento. Also would like it to maintain an online blog/publication of sorts with videos, articles, and the like with privileges to edit the content given to a dozen or so people with different privileges. Want to add a forum to each site that is fairly robust and to possibly add some social networking aspects down the road, so extandability and available plugins/mods in each cms is important. Other than shared login between the forums,blog/publication and store, would like to be able to integrate some content from the forums and blog/publication into the store as well. After researching this a bit, I am inclined towards Drupal, but I haven't found any modules to integrate it with Magento. Also, since the blog content will be done by about a dozen nontechnical people, I want something that is very easy to work with. Lastly, since the site gets a good amount of traffic, speed and security are very important. What CMS would you recommend integrating in this context? Deciding between Drupal, Wordpress and ModX. Also Plone as well. Thanks.

  • Tuning B2B Server Engine Threads in SOA Suite 11g

    - by Shub Lahiri, A-Team
    Background B2B 11g has a number of parameters that can be tweaked to tune the engine for handling high volumes of messages. These parameters are also known as B2B server properties and managed via the EM console.  This note highlights one aspect of the tuning exercise and describes the different threads, that can be configured to tune the performance of a B2B server. Symptoms The most common indicator of a B2B engine in need of a tuning is reflected in the constant build-up of messages in an internal JMS queue within the B2B server. It is called B2B_EVENT_QUEUE and can be monitored via the Weblogic server console. Whenever such a behaviour is seen, it usually results in general degradation of performance. Remedy There could be many contributing factors behind a B2B server's degradation of performance. However, one of the first places to tune the server from the out-of-the-box, default configuration is to change the number of internal engine threads allocated within the B2B server. Usually the default configuration for the B2B server engine threads is not suitable for high-volume of messaging loads. So, it is necessary to increase the counts for 3 types of such threads, by specifying the appropriate B2B server properties via the EM console, namely, Inbound - b2b.inboundThreadCount Outbound - b2b.outboundThreadCount Default - b2b.defaultThreadCount The function of these threads are fairly self-explanatory. In other words, the inbound threads process the inbound messages that are coming into the B2B server from an external endpoint. Similarly, the outbound threads processes the messages that are sent out from the B2B server. The default threads are responsible for certain B2B server-specific special tasks. In case the inbound and outbound thread counts are not specified, the default thread count also dictates the total number of inbound and outbound threads. As found in any tuning exercise, the optimisation of these threads is usually reached via an iterative process. The best working combination of the thread counts are directly related to the system infrastructure, traffic load and several other environmental factors.

  • Preview Chitika Premium Ads On Your Website Quickly

    - by Gopinath
    Google AdSense is an excellent option for publishers like us to monetize traffic. As Google AdSense allow only 3 ad units per page, we have good amount of space left empty on the blog. Why not we use this empty space to earn some revenue(make sure that you are not annoying your visitors with too many ads)? On Tech Dreams today we started experimenting with Chitika Premium Ads to displays advertisements for visitors landing on us through search engines. Chitika Premium Ads are displayed only to US visitors who finds our pages through search engines. Visitors from outside USA does not see these ads anywhere on our site. We being in India, how to preview the Chitika ads on our site? To preview Chitika ads add #chitikatest at the end of the url. For example to preview the ads on Tech Dreams I use the url http://techdreams.org/#chitikatest The above url displays default list of ads Chitika displays. But if you want to see preview of ads for a specific keyword you can append it at the end of the url. Here is another example http://www.techdreams.org/#chitikatest=ipad   Do You Know What The Word “Chitika” Means? What does Chitika mean? When Chitika co-founders, Venkat Kolluri and Alden DoRosario left Lycos in 2003 to start their own company, they sought a name that would suggest the speed with which its customers would be able to put up ads on their Web sites. Chitika, which means “snap of the fingers” in Telugu (a South Indian language), captured this sentiment and Chitika Inc. was born (via) This article titled,Preview Chitika Premium Ads On Your Website Quickly, was originally published at Tech Dreams.

  • Changing frontend cache

    - by Utsav
    Our architecture consists of a front-end cache that most read only users obtain their data from directly. The front-end cache sits in front of a farm of webservers that serve pages written in PHP. We need to be able to detect certain conditions at the front-end cache level and pass those values through to the back-end via HTTP headers. For example we would like to manually tag the carrier network based on the IP address. So, for incoming traffic if the user is say coming from an IP address in the range of "41.202.192.0"/19 we would tag them as being a Orange Cameroon user by setting the appropriate HTTP request header, e.g., X-Carrier = "Orange Cameroon". Based on the setting of this header we would like to vary the cache and serve a different banner to the end user. How would you go about doing this? Keep in mind that we don't want to pollute the cache and we also don't want to create too many small cache segments. Assumptions: You can assume that the X-Carrier has already been detected in our cache. So, for the purposes of your test you can just set this value manually in your example script.

  • Exempt programs from using active VPN connection

    - by Oxwivi
    When I connect to a VPN, all my network traffic is automatically routed through it. Is there a way to add exemptions to that? I don't know if adding exceptions has anything to do with the VPN protocol, but the VPN I'm using is of the OpenVPN protocol. Speaking of OpenVPN, why is it not installed by default on Ubuntu installs unlike PPTP? I could not get the list of IRCHighWay's servers, and this is the result I get trying to connect on XChat with running the bash script running: * Looking up irc.irchighway.net * Connecting to irc.irchighway.net (65.23.153.98) port 6667... * Connected. Now logging in... * You have been K-Lined. * *** You are not welcome on this network. * *** K-Lined for Open proxies are not allowed. (2011/02/26 01.21) * *** Your IP is 173.0.14.9 * *** For assistance, please email [email protected] and include everything shown here. * Closing Link: 0.0.0.0 (Open proxies are not allowed. (2011/02/26 01.21)) * Disconnected (Remote host closed socket). The IP 173.0.14.9 is the one due to my VPN. I had forgotten to check ip route list before running the script, and this is the one after running it: ~$ ip route list 99.192.193.241 dev ppp0 proto kernel scope link src 173.0.14.9 173.0.14.2 via 192.168.1.1 dev eth1 proto static 173.0.14.2 via 192.168.1.1 dev eth1 src 192.168.1.3 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.3 metric 2 169.254.0.0/16 dev eth1 scope link metric 1000 default dev ppp0 proto static Oh and running the script returned this output: ~$ sudo bash irc_route.sh Usage: inet_route [-vF] del {-host|-net} Target[/prefix] [gw Gw] [metric M] [[dev] If] inet_route [-vF] add {-host|-net} Target[/prefix] [gw Gw] [metric M] [netmask N] [mss Mss] [window W] [irtt I] [mod] [dyn] [reinstate] [[dev] If] inet_route [-vF] add {-host|-net} Target[/prefix] [metric M] reject inet_route [-FC] flush NOT supported I ran the script after connecting to the VPN.

  • How to protect your real time online shooter from potential bots

    - by Zaky German
    I'm looking to create a multiplayer top down shooter. While i've read about different topics, i can see them i've got some real challenges ahead, but i'm all up for it. One thing i can't understand is how am i supposed to be protecting the game from people who try to create bots? What i mean is, as far as i understand, it's impossible to protect the network traffic in a way that players won't be able to create programs that listen to what's going on and understand it. So what worries me is that people can create bots that listen to the current location of rival players, and send communication that mimic as if the player is shooting in the exact "perfect" location to win that match. So what kind of techniques are used to protect real time games from such bots? Also i'd like to mention that i've tried searching for discussions (as this sounds like something many people struggle with), but couldn't find anything about it specifically, only as a part of broader questions about networking in real time games. If i should have looked harder feel free to put me in my place :) Thanks alot!

Weird for me as never bought an SSL. My site is a blog only. When spoke to Google forums, ( https://productforums.google.com/forum/#!msg/webmasters/2Hz46t44nwk/7voZWudFtAQJ ), they say I should redirect https to http. Now when I have redirected this using the above method, I am still getting SSL warning in browsers. And found that Google is still indexing my new pages with https. I feel as I do not have an SSL, adding a redirect in https doesn't work. So if Google indexes my https page, then I should go and buy SSL, and tell there to redirect https to http. Why would I do that? Please help me, reduced the traffic by nearly 30% because of this. Have even told search engines to go to this file (disallows everything) if they are on https.

  • Share on: FB, Tweet, Digg, Linkedin, Delicious, My mother, ... it's just on fashion, or some real value?

    - by Marco Demaio
    Nowadays your site is not in fashion if you don't show at least a couple of share buttons like these: Is this just fashion, or do people actually get something good out of it? When I say "something good" I mostly mean something that you could measure, and not just the feeling that was good. Maybe I can better explain with an example: did you notice (in some way) that many people clicked on those links to share your page/s on those web 2.0 social sites? And in such a case on which social networks did you see they mostly share your pages? BTW I'm not talking about Google PR, i know all web 2.0 social sites use nofollow everywhere and even hidden links, so they are useless by themselves for PR. UPDATE: According to this video, Google's Alter Ego says that they now use in some way data from social sites in ranking. If this is true, it's obvious that the Share on button for FB, Tweet, etc are definitely of some values. But again my question is more about what you noticed in your real experience to be a direct benefit of adding those type of "Share On" links on your webisite? I.e. did you see more traffic coming in form FB, or some users who bought your products because of FB or Twitter? Or any other benefits? Thanks

  • Authentication system brainstorm

    - by gansbrest
    Hi. We got multiple small websites (microsites) and one main high traffic one with big users base. Right now the requirement is to build authentication system which should allow users to loign with the same identity across the network. All website are running on different domains, powered by Drupal 6 CMS and have separate databases (so sharing tables with prefix is not an option + it creates a huge mess in the db). Here is the set of core requirements I came up with: Users should be able to login with the same credentials to all sites within the network User’s data sharing between Main site (storage) and all micro sites within the network Data synchronization across the network when user changes the data (update email or password for example) The login/registration process should be seamless and consistent Register on any of the sites across the network and use that identity to login later on. In the future there might be a need to add openid authentication options. Basically we are looking at something similar stackexchange does, but not sure if they have central users base on not. I was thinking about custom solution which will include 2 parts (modules), one will be stored on the Main site for users data storing and responding to requests from clients. Second part (module) will be placed on each microsite, which is going to send requests to the Master. Some kind of client - server setup. One of the complications I see right away is #3. Data Synhcronization across the network. I just don't want to reinvent the wheel and maybe some work is already done in this direction. Looking forward to your ideas on how to approach this project. EDIT: We use MySQL database

  • How to I access "Deny" message from a Lidgren client?

    - by TJ Mott
    I'm using the Lidgren v3 network for a UDP client/server networking model. On the server end, I'm initializing a NetServer object with the NetIncomingMessage.ConnectionApproval message type enabled. So the client is able to successfully connect and the first packet it sends is a login packet, containing a username and password supplied by the user. The server is receiving that and doing some black magic to authenticate, and everything works up to that point. If the login fails, the server calling NetIncomingMessage.SenderConnection.Deny("Invalid Login Credentials"). I want to know how to properly receive this deny message on the client. I'm getting the message, it shows up with a message type of NetIncomingMessage.StatusChanged. If I call ReadString on that message, I get a corrupted version of the string I passed to the Deny method on the server. The type of corruption varies, I've seen odd characters in there but in every case it's truncated and is way shorter than the string I entered. Any ideas? The official documentation is sparse on this topic. I could use pointers from anyone who has successfully used the Lidgren library and uses the Accept or Deny methods. Also, if I don't do any authentication and just Approve() the connection every time, stuff actually works just fine and I'm getting reliable two-way UDP traffic. (And lastly, Stack Exchange said I don't have enough reputation to use the "Lidgren" tag....???)

  • How often does Dreamhost change IP Addresses

    - by pjreddie
    So I just migrated our site to dreamhost because they are free for non-profits. However, right after I switched the nameservers over to them they changed the IP address of the site. So first they propagated out IP address x.x.x.180, then they switched it to x.x.x.178 and had to propagate that out. Point being it meant a lot of downtime since a lot of big DNS servers (like google) thought the address was still x.x.x.180 for up to 5 hours after they switched it. This is compounded by the fact that most our visitors to the site live here in Unalaska and we have local DNS servers that take a LONG time to update (like a day or more) since we get all our internet over satellite. So every time Dreamhost changes our IP address it can mean a day of downtime for us in our community. So my question is, how often do these changes take place? I asked Dreamhost support and they gave me a vague response: I wish I could say, however those changes happen at random times. They're not that frequent, maybe even months between updates, but there's no way to know for sure. First, I hardly believe that they don't know their own system well enough to give me at least some estimate or average. Second, is it worth looking at other providers so that I can get a static IP address? We were hosting the site here originally and hadn't run into this problem since we have a static IP here. We don't get a ton of traffic but usually around 500 hits a day or so, sometimes more if our stories are featured on statewide or national news broadcasts. So hours of downtime every time Dreamhost "randomly" decides to move our server location can be bad for our readership.

    copyright 2012 Rob Lang Fair is fair. Our last post featured a conversation with the beautiful and talented Eva Mendez, so today we're featuring something for those of you who prefer the other gender of our fair species. This dude has quite the hardware challenge ahead of him. He hasn't begun to find out what's really under that hood. Life is much easier for you and me, thanks to Jeff Wright and Suzanne Zorn. They wrote a wicked cool article about Oracle VM Server for SPARC. Here's a little bit about it... Looking Under the Hood of Networking in Oracle VM Server for x86 Oracle VM Server for SPARC lets you create logical networks out of physical Ethernet ports, bonded ports, VLAN segments, virtual MAC addresses (VNICs), and network channels. You can then assign channels (or "roles") to each logical network so that it handles the type of traffic you want it to. Greg King explains how you go about doing this, and how Oracle VM Server for SPARC implements the network infrastructure you configured. He also describes how the VM interacts with paravirtualized guest operating systems, hardware virtualized operating systems, and VLANs. Finally, he provides an example that shows you how it all looks from the VM Manager view, the logical view, and the command line view of Oracle VM Server for x86.

Here are the options I turned on: Subdomains of mydomain ON Examples: www.mydomain.com -and- apps.mydomain.com -and- store.mydomain.com Multiple top-level domains of mydomain ON Examples: mydomain.uk -and- mydomain.cn -and- mydomain.fr Which gave me the following code: _gaq.push(['_setAccount', 'UA-123456789-1']); _gaq.push(['_setDomainName', 'mydomain.com']); _gaq.push(['_setAllowLinker', true]); _gaq.push(['_trackPageview']); In this help page I read that _setDomainName must be changed for each domain which I did: -if you go to mydomain.net you get _gaq.push(['_setDomainName', 'mydomain.net']); -if you go to mydomain.com you get _gaq.push(['_setDomainName', 'mydomain.com']); When I generate traffic on both mydomain.dom and mydomain.net and watches GA push requests made with firebug I can see requests generated for both domains and the parameter called utmhn has the proper domain value (which matches that of _setDomainName and the browser address bar). However when I monitor the realtime statistics under Home->Real-Time->Overview I see pageviews for mydomain.net BUT NOT for mydomain.dom :( What am I missing to properly track both domains? PS: in the help page I mentioned they talk about setting up cross links which I didn't do for now as my understanding is that it shouldn't be needed to get what I'm trying to do to work. Also I want to mention that I do not have any tracking code for any of these 2 domains other than the one I mentioned.

  • High Performance SQL Views Using WITH(NOLOCK)

    - by gt0084e1
    Every now and then you find a simple way to make everything much faster. We often find customers creating data warehouses or OLAP cubes even though they have a relatively small amount of data (a few gigs) compared to their server memory. If you have more server memory than the size of your database or working set, nearly any aggregate query should run in a second or less. In some situations there may be high traffic on from the transactional application and SQL server may wait for several other queries to run before giving you your results. The purpose of this is make sure you don’t get two versions of the truth. In an ATM system, you want to give the bank balance after the withdrawal, not before or you may get a very unhappy customer. So by default databases are rightly very conservative about this kind of thing. Unfortunately this split-second precision comes at a cost. The performance of the query may not be acceptable by today’s standards because the database has to maintain locks on the server. Fortunately, SQL Server gives you a simple way to ask for the current version of the data without the pending transactions. To better facilitate reporting, you can create a view that includes these directives. CREATE VIEW CategoriesAndProducts AS SELECT * FROM dbo.Categories WITH(NOLOCK) INNER JOIN dbo.Products WITH(NOLOCK) ON dbo.Categories.CategoryID = dbo.Products.CategoryID In some cases quires that are taking minutes end up taking seconds. Much easier than moving the data to a separate database and it’s still pretty much real time give or take a few milliseconds. You’ve been warned not to use this for bank balances though.

  • Exchange 2010 Deployment Notes - ISA 2004 Server Issue

    - by BWCA
    An interesting ISA 2004 tidbit … While we were setting up our Exchange 2010 ActiveSync environment, we encountered a problem where we could not successfully telnet over port 443 from one of our ISA 2004 Servers to our Exchange 2010 Client Access Server Array. When we tried to telnet over port 443 from the ISA Server to the Client Access Server Array name, we would get a “Could not open connection to the host on port 443: Connect failed” error message. Also, when we used portqry over port 443 from the ISA Server to the Client Access Server Array name, we would get a “Error opening socket: 10065” and “No route to host” error messages. It was odd because we did not have any problems with using ping or tracert from the ISA Server to the Client Access Server Array and our firewall firewall policy was allowing 443 traffic to pass through. After some troubleshooting, we were able to telnet and use portqry over port 443 successfully if we stopped the Microsoft Firewall service on the ISA 2004 Server.  So, it was strictly a problem with ISA.  Eventually, we were able to isolate the problem to a ISA 2004 Server System Policy setting as shown below (to modify the System Policy, right-click Firewall Policy and click Edit System Policy). Under the Diagnostics Services – HTTP Connectivity verifiers Configuration Group, you need to enable the configuration group under the General tab to resolve the problem.  After we enabled the setting, we no longer had a problem.

  • What is recommended minimum object size for gzip benefits?

    - by utt73
    I'm working on improving page speed display times, and one of the methods is to gzip content from the webserver. Google recommends: Note that gzipping is only beneficial for larger resources. Due to the overhead and latency of compression and decompression, you should only gzip files above a certain size threshold; we recommend a minimum range between 150 and 1000 bytes. Gzipping files below 150 bytes can actually make them larger. We serve our content through Akamai, using their network for a proxy and CDN. What they've told me: Following up on your question regarding what is the minimum size Akamai will compress the requested object when sending it to the end user: The minimum size is 860 bytes. My reply: What is the reason(s) for why Akamai's minimum size is 860 bytes? And why, for example, is this not the case for files Akamai serves for facebook? (see below) Google recommends to gzip more agressively. And that seems appropriate on our site where the most frequent hits, by far, are AJAX calls that are <860 bytes. Akamai's response: The reasons 860 bytes is the minimum size for compression is twofold: (1) The overhead of compressing an object under 860 bytes outweighs performance gain. (2) Objects under 860 bytes can be transmitted via a single packet anyway, so there isn't a compelling reason to compress them. So I'm here for some fact checking. Is the 860 byte limit due to packet size the end of this reasoning? Why would high traffic sites push this lower/closer to the 150 byte limit... just to save on bandwidth costs, or is there a performance gain in doing so?
