• Is my robots.txt working as it should?

  - by TigerBlood

  I want crawlers to have access to http://www.example.com but not http://www.example.com/ My robots.txt is as follows: User-agent: * Allow: /$ Disallow: / My site is in google search results, but I am not coming up in Bing, Yahoo, etc. I have had the same robots.txt since last year, and I initially requested inclusion ~1 year ago, having also resubmitted the URL to those latter search engines several times since as well. Is my robots.txt blocking those other crawlers? And if so, why not google as well? Thanks in advance!

• How to prevent a 404 Error when installing a subdomain using a wordpress multi-site installation

  - by Chris

  I have installed a multi-site instillation of WordPress onto my domain. I then added the necessary code to the wp-config.php file and .htaccess as instructed by WordPress. I also installed a plugin called Quick Page/Post Redirect Plugin which allowed me to place a 301 redirect onto the main domain as I only want to use the sub domain and not the main domain. Then I also added the following line of code to the wp-config.php file to redirect the main domain define( 'NOBLOGREDIRECT', 'URL Redirect Address' ); The site works fine with a redirect on the main domain and my subdomain runs fine when you type in subdomain.domain.com or http://subdomain.domain.com. However when I enter www.subdomain.domain.com or http://www.subdomain.domain.com the following error message is returned: Not Found The requested URL / was not found on this server. Apache/2.4.9 (Unix) Server at www.subdomain.domain.com Port 80 Any help with this would be much appreciated.

• Ipython and Matplotlib in Ubuntu 13.10

  - by LuizAngioletti

  I've recently updated my Ubuntu to the 13.10 version. To my surprise, Ipython and Matplotlib are available only in versions prior to those I had in my previous 12.04 LTS install. When with the 12.04, I had the Julian Taylor PPA set up in my repositories, and that's why (I think) I had most up-to-date versions from both packages. The versions currently in 13.10 are: Matplotlib: 1.2.1 (http://matplotlib.org/index.html, most current version is 1.3.1) Ipython: 0.13.2 (http://ipython.org, most current version is 1.1.0 – September 2013) Is there any PPA available for the 13.10? The JTaylor ppa covers only as far as 12.10 (Quantal, link not available due to reputation rank in stack exchange) Should I install those packages outside apt? Isn't that troublesome?

• Ubuntu 13.10. Can't access Internet and unable to install anything

  - by Crandacular

  After upgrading to Ubuntu 13.10 I was not able to access the Internet on any program that required it. So I uninstalled Firefox but I could reinstall from the software center so I used the terminal, everything ran smoothly, I told me how much additional space would be used, then it said "Err http://us.archive.ubuntu.com /ubuntu/ saucy/main Firefox i386 24.0+build1-0ubuntu1 Could not resolve 'us.archive.ubuntu.com Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/f/firefox/firefox_24.0+build1-0ubuntu1_i386.deb Could not resolve 'us.archive.ubuntu.com' E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?" And with both given possible fixes I also get errors. Please help, it's been like this sense the day the 13.10 update was released

• Add ability to add tabs to the end of a line in Windows PowerShell ISE

  - by deadlydog

  Originally posted on: http://geekswithblogs.net/deadlydog/archive/2013/06/24/add-ability-to-add-tabs-to-the-end-of-a.aspxIn the preamble of an earlier post I mentioned that one of the little things that bugs me about Windows PowerShell ISE is that you can add tabs to the start of a line, but not to the end of a line.  This is likely because it would interfere with the tab-completion feature.  I still like to be able to put tabs on the end of my code lines though so that I can easily line up my comments.  Here is how we can achieve this functionality in PowerShell ISE.

• Trim on encrypted SSD--Urandom first?

  - by cb474

  My understanding (I'm not sure I'm getting this all right) is that if one uses Trim on an encrypted SSD, it defeats some of the security benefits, because the drive will write zeros to empty space (as files are deleted). See: http://www.askubuntu.com/questions/115823/trim-on-an-encrypted-ssd And: http://asalor.blogspot.com/2011/08/trim-dm-crypt-problems.html My question is: From the perspective of the performance of the SSD and the functioning of Trim, would it therefore be better to simply zero out the SSD, before setting up an encrypted system, rather than writing random data to the drive, with urandom, as one usually does? Would this basically leave one with the same level of security anyway? And more importantly, would it better enable the Trim functionality to work as intended, with the encrypted SSD?

• Jquery Carousel - Need A Script Hack to Customize

  - by Leah

  I hope someone can help me out here. I am coding a site for a client using the carouFredsel. I am using this because it allows for variable widths with in the slideshow as seen here: http://2938.sandbox.i3dthemes.net/index-old.html. My problems are as follows: to use the built in auto center script the scrolling changes the white space in between images during the transition to fit the width of the wrapper. I need a hack to keep the white space during transition the same, like this: http://2938.sandbox.i3dthemes.net/index.html. Also, I can't figure out how to put this snippet into my code and make it work scroll: { onAfter: function() { if ( $(this).triggerHandler( "currentPosition" ) == 0 ) { $(this).trigger( "pause" ); } } }

• SH404SEF URLs in Joomla 1.5

  - by Tao Bellamine

  I have two modules to play with urls, the global configuration module and the sh404sef module. The global config is set to "Sef urls: YES" and "mod rewrite enabled: YES" and the sh404sef is set "url optimization: NO". My problem is, even with "Sef urls" set in the global config, my urls still don't seem to be that "user friendly" so I turn on the "Url optimization" using the sh404sef module, and I get better descriptive urls. However, the problem I inherit from doing this is that my dynamically populated chronoforms get messed up (only the chrono forms, other forms are fine); These forms are now showing up at the homepage instead of their own reserved page. Here's an example: Old form "GOOD" url: http://www.mycraftwork.com/index.php?option=com_content&view=article&id=94 New optimized "BAD" URL: http://www.mycraftwork.com/handthrown-pottery/alladin-teapot/index.php?option=com_content&view=article&id=94 Any help would be GREATLY appreciated! I can even turn the sh404sef on and off if some people are interested in seeing the issue LIVE. Thanks!! Tao Bellamine

  I have a Radeon HD 4650 AGP card. The installation instructions at http://wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide download catalyst 12.1 However, there is no download available at http://support.amd.com/us/gpudownload/Pages/index.aspx for my AGP card. Only Windows drivers are available. Should I go ahead and use the guide and manually install 12.1? I assume it's not on the amd website for a reason, but I was wondering if anybody had any experience with this. Thanks!

• Memory Management/Embedded Management in C

  - by Sauron

  Im wondering if there is a set or a few good books/Tutorials/Etc.. that go into Memory Management/Allocation Specifically (or at least have a good dedicated section to it) when it comes to C. This is more for me learning Embedded and trying to keep Size down. I've read and Learned C fine, and the "standard" Learning books. However most of the books don't spend a huge amount of time (Understandably since C is pretty huge in general) going into the Finer details about whats going on Down Under. I saw a few on Amazon: http://www.amazon.com/C-Pointers-Dynamic-Memory-Management/dp/0471561525 http://www.amazon.com/Understanding-Pointers-C-Yashavant-Kanetkar/dp/8176563587/ref=pd_sim_b_1 (Not sure how relevant this would be) A specific Book for Embedded that has to do with this would be nice. But Code Samples or...Heck tutorials or anything about this topic would be helpful!

• Using Network load balancing to distribute load for SharePoint2010 – Part3 of building my own development SharePoint2010 Farm

  - by ybbest

  Part1 of building my own development SharePoint2010 Farm Part2 of building my own development SharePoint2010 Farm Part3 of building my own development SharePoint2010 Farm In my last post, I have installed SharePoint2010 in one of the server (WFE One) and configured using the OOB SharePoint configuration wizard. In this post I will show you how to use OOB windows network load balancing to distribute load for SharePoint2010 site. 1. Install SharePoint in another server WFE Two (you can follow the steps in my last post), but instead of choosing create new Farm, you need to select “connect to existing farm” this time. 2. Click next then click retrieve database names button and select the farm configuration database. 3. Click next and enter the passphrase you specified when you first installed the SharePoint Farm. 4. Click the advanced settings and select Use this machine to host the web site. 5. Click OK to finish the configurations 6. Next, Install NLB in the two WFE (web front end) SharePoint servers 7. Configure NLB to create the cluster. Go to Start—Administrative Tools—Network Load Balancing Manager 8. Right-click the Network Load Balancing Clusters Node and select New Cluster. 9. Type in the host name that is to be part of the new cluster. 10. Type in the IP address for the cluster. 11. Select the Multicast for this cluster.(The default one is Unicast) 12. You can configure the Port Rules for the clustering , but I will leave the default here. 13. Add another WEF to the cluster. 14. Type in the host name that is to be part of the new cluster. 15. Set the Priority to 2. 16. Click Next to complete the cluster setup. 17. Create an entry in the DNS for the new cluster. 18. Add the binding to the IIS site in the IIS Manager 19. Change the Alternate access mapping for you default site collection from http://sp2010wefone to http://team 20. Browse to http://Team , you will be redirected to the SharePoint site.

• Current state of the art for holographic displays?

  - by kamziro

  In another thread I was asking about independent arcade system development, and partly it was because I'm interested in using available 3D holographic technology for the displays. I saw one which involved a rotating mirror at very high speeds, so that's probably not going to be too feasible (I'd hate to think of what happens when something goes wrong). However, I looked around for videos from trade shows, and I found this: http://www.youtube.com/watch?v=Vl0EIngM-RA But information is scarce, and I'm led to believe it's just using mirrors and reflections, and does not convey true 3D depth like the one using rotating mirrors at high speed: http://www.youtube.com/watch?v=YKCUGQ-uo8c So yeah, does anyone know if there's something better available today?

• LuaJit FFI and hiding C implementation details

  - by wirrbel

  I would like to extend an application using LuaJit FFI. Having seen http://luajit.org/ext_ffi_tutorial.html this is surprisingly easy when comparing this to the Lua C API. So far so good. However I do not plainly want to wrap C functions but provide a higher level API to users writing scripts for the application. Especially I do not want users to be able to access "primitives", i.e. the ffi.* namespace. Is this possible or will that ffi namespace be available to user's Lua scripts? On the issue of Sandboxing Lua I found http://lua-users.org/wiki/SandBoxes which is not talking about FFI though. Furthermore, the plan I have described above is assuming that the introduction of abstraction layers happens on the lua side of code. Is this an advisable approach or would you rather abstract functionality on the statically compiled code (on the C-side)?

• ANTS Memory Profiler 7.0

  - by Sam Abraham

  In the next few lines, I would like to briefly review ANTS Memory Profiler 7.0.  I was honored to be extended the opportunity to review this valuable tool as part of the GeeksWithBlogs influencers Program, a quarterly award providing its recipients access to valuable tools and enabling them with an opportunity to provide a brief write-up reviewing the complimentary tools they receive.   Typical Usage   ANTS Memory Profiler 7.0 is very intuitive and easy to use for any user be it novice or expert. A simple yet comprehensive menu screen enables the selection of the appropriate program type to profile as well as the executable or site for this program.   A typical use case starts with establishing a baseline memory snapshot, which tells us the initial memory cost used by the program under normal or low activity conditions. We would then take a second snapshot after the program has performed an activity which we want to investigate for memory leaks. We can then compare the initial baseline snapshot against the snapshot when the program has completed processing the activity in question to study anomalies in memory that did not get freed-up after the program has completed its performed function. The following are some screenshots outlining the selection of the program to profile (an executable for this demonstration’s purposes).   Figure 1 - Getting Started   Figure 2 - Selecting an Application to Profile     Features and Options   Right after the second snapshot is generated, Memory Profiler gives us immediate access to information on memory fragmentation, size differences between snapshots, unmanaged memory allocation and statistics on the largest classes taking up un-freed memory space.   We would also have the option to itemize objects held in memory grouped by object types within which we can study the instances allocated of each type. Filtering options enable us to quickly narrow object instances we are interested in.   Figure 3 - Easily accessible Execution Memory Information   Figure 4 - Class List   Figure 5 - Instance List   Figure 6-  Retention Graph for a Particular Instance   Conclusion I greatly enjoyed the opportunity to evaluate ANTS Memory Profiler 7.0. The tool's intuitive User Interface design and easily accessible menu options enabled me to quickly identify problem areas where memory was left unfreed in my code.     Tutorials and References  FInd out more About ANTS Memory Profiler 7.0 http://www.red-gate.com/supportcenter/Product?p=ANTS Memory Profiler   Checkout what other reviewers of this valuable tool have already shared: http://geekswithblogs.net/BlackRabbitCoder/archive/2011/03/10/ants-memory-profiler-7.0.aspx http://geekswithblogs.net/mikebmcl/archive/2011/02/28/ants-memory-profiler-7.0-review.aspx

• 302 Redirect causes garbage at end of Wordpress link in Facebook

  - by Joao

  When I try to link my Wordpress blog to Facebook, the url doesn't resolve properly. There's garbage appended at the end and Facebook is not able to retrieve information from the site. Happens in every page, post or main entry. Here's what happens: http://clarissarezende.com.br/ shows up in Facebook as http://clarissarezende.com.br/UPLcS/ (when copy/paste the link) and no information about the site shows up in FB. I'm using Wordpress 3.3.1 with ProPhoto 4. Recently I moved the DNS entry on my ISP. The blog is hosted at clarissarezende.com.br/public_html/blog2 and before the DNS would point to public_html and then I changed it to public_html/blog2. Note that I did not move any Wordpress files. Made the (I think) necessary changes all over Facebook, but still no dice... Any ideas on what can be happening?

• Workflow 4.5 is Awesome, cant wait for 5.0!

  - by JoshReuben

  About 2 years ago I wrote a blog post describing what I would like to see in Workflow vnext: http://geekswithblogs.net/JoshReuben/archive/2010/08/25/workflow-4.0---not-there-yet.aspx At the time WF 4.0 was a little rough around the edges – the State Machine was on codeplex and people were simulating state machines with Flowcharts. Last year I built a near- realtime machine management system using WF 4.0.1 – its managing the internal operations of this device: http://landanano.com/products/commercial   Well WF 4.5 has come a long way – many of my gripes have been addressed: C# expressions - no more VB 'AndAlso' clauses state machine awesomeness - can query current state many designer improvements - Document Outline is so much more succinct than Designer! Separate WCF Service Contract interfaces and ability to generate activities from contract operations ability to rehydrate to updated flow definitions via DynamicUpdateMap and WorkflowIdentity you can read about the new features here: http://msdn.microsoft.com/en-us/library/hh305677(VS.110).aspx   2013 could be the year of Workflow evangelism for .NET, as it comes together as the DSL language. Eg on Azure it could be used to graphically orchestrate between WebRoles, WorkerRoles and AppFabric Queues and the ServiceBus – that would be grand.   Here’s a list of things I’d like to see in Workflow 5.0: Stronger Parallelism support for true multithreaded workflows . A Workflow executes on a single thread – wouldn’t it be great if we had the ability to model TPL DataFlow? Parallel is not really parallel, just allows AsyncCodeActivity.     support for recursion an ExpressionTree activity with an editor design surface a math activity pack return of application level protocol (3.51 WF services) – automatically expose a state machine as a WCF service with bookmark Receive activities generated from OperationContract automatically placed in state transition triggers. A new HTML5 ActivityDesigner control – support with different CSS3  skinnable hooks,  remote connectivity (had to roll my own) A data flow view – crucial to understanding the big picture Ability to refactor a Sequence to custom activity in a separate .xaml file – like Expression Blend does for UserControl state machine global error handling - if all states goto an error state, you quickly get visual spagetti. Now you could nest a state machine, but what if you want an application level protocol whereby each state exposes certain WCF ops. DSL RAD editing - Make the Document Outline into a DSL editor for adding activities  – For WF to really succeed as a higher level of abstraction, It needs to be more productive than raw coding - drag & drop on the designer is currently too slow compared to just typing code. Extensible Wizard API - for pluggable WF editor experience other execution models beyond Sequence, Flowchart & StateMachine: SSIS, Behavior Trees,  Wolfram Model tool – surprise us! improvements to Designer debugging API - SourceLocation is tied to XAML file line number and char position, and ModelService access seems convoluted - why not leverage WPF LogicalTreeHelper / VisualTreeHelper ? Workflow Team , keep on rocking!

• Question about Partitioning

  - by Trent C

  I am looking to dual boot Windows 7 and Ubuntu 13.10. I have been using windows for work and school for over a year, and have about 100 gig of stored files (backed up of course) and some paid programs. Because of this, I really want my partitioning experience to go well. Unfortunately, I am running into a bit of an anomoly When I load GPart, I see that my sda drive is unallocated http://i.imgur.com/Hi2XhIr.png Whereas my sdb appears to contain all of the windows files and partitions, and make up my C: drive http://i.imgur.com/aaCOXje.png Is this going to be an issue, as all literature on dual boot installation references sda? How do I work around it? System Info: Lenovo IdeaPad Y570- 750GB HDD with 64GB SSD Processor: Intel® Core™ i7-2670QM CPU @ 2.20GHz × 8

• How to get rid of 'grub rescue'?

  - by SaM

  While logged into Windows, I deleted a disk partition which was containing Ubuntu. When I restarted my pc, it is showing 'grub rescue' command prompt. How to boot windows now? I no longer require Ubuntu. I have Ubuntu live CD When I tried the following commend: sudo apt-get install lilo the following error is shown: Err http://archive.ubuntu.com/ubuntu/ natty/main lilo i386 1:22.8-10ubuntu1 404 Not Found [IP: 91.189.92.156 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/l/lilo/lilo_22.8-10ubuntu1_i386.deb 404 Not Found [IP: 91.189.92.156 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

• How are generics implemented?

  - by greenoldman

  This is the question from compiler internals perspective. I am interested in generics, not templates (C++), so I marked the question with C#. Not Java, because AFAIK the generics in both languages differ in implementations. When I look at languages w/o generics it is pretty straightforward, you can validate the class definition, add it to hierarchy and that's it. But what to do with generic class, and more importantly how handle references to it? How to make sure that static fields are singular per instantiations (i.e. each time generic parameters are resolved). Let's say I see a call: var x = new Foo<Bar>(); Do I add new Foo_Bar class to hierarchy? Update: So far I found only 2 relevant posts, however even they don't go into much details in sense "how to do it by yourself": http://www.jprl.com/Blog/archive/development/2007/Aug-31.html http://www.artima.com/intv/generics2.html
