  • Free SEO Analysis using IIS SEO Toolkit

    In my spare time Ive been thinking about new ideas for the SEO Toolkit, and it occurred to me that rather than continuing trying to figure out more reports and better diagnostics against some random fake sites, that it could be interesting to ask openly for anyone that is wanting a free SEO analysis report of your site and test drive some of it against real sites. So what is in it for you, I will analyze your site to look for common SEO errors, I will create a digest of actions to do and other...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • best way to go about cost-benefit analysis on hardware

    - by Michael
    I'm looking to build a low-end computational server (my jargon in this field is especially limited so if someone can state that better please change that to meet jargon). I'm basically running computational fluid dynamics programs, large matrix computations and bioinformatics code. What would be the best way to approach cost/benefit analysis on what to put in the system? Perhaps even more general: How does one approach cost/benefit analysis on hardware theoretically (doing the analysis before building the machine)?

  • Do I need to retain Sharepoint usage analysis log files

    - by dunxd
    Our Sharepoint installation currently has 30Gb of Usage Analysis Log file - these date back about six months. I have configured Sharepoint to do Usage Analysis Processing every night, so I am wondering whether I need to keep these files for so long. Sharepoint doesn't seem to clean up these files automatically - I think six months ago I had to clear out logs due to disk space issues. So my question is, do I need to retain these files in order to get decent usage analysis reports, or can I delete them as soon as the usage analysis processing has completed?

  • Connecting client to JBoss cluster

    - by Nivek
    I am new to JBoss. Basically I have managed to cluster 2 nodes with: Node 1: run.bat -c all -g DefaultPartition –u 230.0.0.4 -b 10.67.51.28 -Djboss.messaging.ServerPeerID=1 Node 2: run.bat -c all -g DefaultPartition –u 230.0.0.4 -b 10.67.50.21 -Djboss.messaging.ServerPeerID=2 I know that if i cofigure a Apache load balancing(Mod_JK) to sit infront of the cluster, the client simply just punch in the IP of the Apache, and Apache will redirect the traffic to the nodes. But I do not want to have a Apache infront of the cluster. So how do my client access the cluster?? Do i need to configure something in JBoss, or isit a MUST to have a load balancer for the client to access the cluster?? MANY thanks in advance....

  • What is the best way/tool to analyze raw data(network stats) from Simulation?

    - by user90500
    After running a simulation(using a simulator(QualNet)) of a simulated network I end up with ip stats stored in a database, I then extract the data to a csv file So now I have 750mb of raw network stats(time stamp, packet id, source ip, source port, protocol, etc). What are the common ways of analyzing large amounts of data like above, if you want to know things like packet loss, throughput, delay, congestion, etc.

  • Are there any C++ tools that detect misuse of static_cast, dynamic_cast, and reinterpret_cast?

    - by chrisp451
    The answers to the following question describe the recommended usage of static_cast, dynamic_cast, and reinterpret_cast in C++: http://stackoverflow.com/questions/332030/when-should-static-cast-dynamic-cast-and-reinterpret-cast-be-used Do you know of any tools that can be used to detect misuse of these kinds of cast? Would a static analysis tool like PC-Lint or Coverity Static Analysis do this? The particular case that prompted this question was the inappropriate use of static_cast to downcast a pointer, which the compiler does not warn about. I'd like to detect this case using a tool, and not assume that developers will never make this mistake.

  • VS2010 Code Analysis, any way to automatically fix certain warnings?

    - by JL
    I must say I really like the new code analysis with VS 2010, I have a lot of areas in my code where I am not using CultureInfo.InvariantCultureand code analysis is warming me about this. I am pretty sure I want to use CultureInfo.InvariantCulturewhere ever code analysis has detected it is missing on Convert.ToString operations. Is there anyway to get VS to automatically fix warnings of this type?

  • Scoring/analysis of Subjective testing for skills assessment

    - by ChrisBint
    I am lucky in the sense that I have been given the opportunity to be a 'Technical Troubleshooter' for our offshore development team. While I am confident and capable of dealing with most issues, I have come across something that I am not. Based on initial discussions with various team members both on and offshore, a requirement for a 'repeatable, consistent' skills assessment has been identified. In my opinion, the best way to achieve this would be a combination of objective and subjective tests. The former normally being an initial online skills assessment on various subjects, for example General C#, WCF and MVC. The latter being a technical test where the candidate would need to solve various problems and (hopefully) explain the thought processes involved with the solution whilst doing so. Obviously, the first method is consistent, repeatable and extremely accurate. The second is always going to be subjective and based on the approach, the solution (or possibly not) and other factors. The 'scoring' of this is also going to be down to the experience and skills of the assessor and this is where my problem lies; The person that is expected to be the assessor initially (me) has no experience. The people that will ultimately continue this process for other people will never remain the same due to project constraints and internal reasons, this changes the baseline for comparison. I am not aware of any suitable system that can be classed as consistent and repeatable for subjective tests with the 2 factors above, let alone if those did not exist. So anyway, I have to present a plan that will ultimately generate a skills/gap analysis and it is unlikely that I will be able to use an objective method (budget constraints most likely reason). The only option left is the subjective methods and the issues above. Does anyone have any suggestions for an approach that may tick all the boxes?

  • WolframAlpha Can Now Do In-depth Analysis of Your Facebook Account

    - by Jason Fitzpatrick
    If you’re a big fan of WolframAlpha’s ability to crunch the numbers on just about anything–and we certainly are–you’ll likely be just as delighted as we were to watch it massage the data from your Facebook account. Find out your most liked, discussed, and shared posts, see your Facebook habits, and other neat trends. I unleashed it on my account this morning, not sure what to expect from the results. Within the results tabulation WolframAlpha provided me with all sorts of neat data break downs. I now know exactly how many days it is to my next birthday, the composition of my aggregate posting habits (how many posts are status updates, links, or photos), the time of day when I do the most posting (and what the composition of those posts is), and my average post length. I also know my most liked post and my most commented on post. It will even crunch the numbers on your network of friends (60.6% of my friends are married, for example). By far one of the more interesting data analysis it does on the friendship data, however, is organizing all your friends into relationship clusters so you can see who in your Facebook network is friends with other people in your Facebook network. The service from WolframAlpha is free: simply visit the WolframAlpha search portal and type in “Facebook report” to start the process. You’ll be prompted to create a WolframAlpha account if you don’t have one and to authorize the WolframAlpha Facebook app to access your data. Your Facebook data is cached to your WolframAlpha account for one hour in order to crunch the numbers and display the results.

  • Software Architecture Analysis Method (SAAM)

    Software Architecture Analysis Method (SAAM) is a methodology used to determine how specific application quality attributes were achieved and how possible changes in the future will affect quality attributes based on hypothetical cases studies. Common quality attributes that can be utilized by this methodology include modifiability, robustness, portability, and extensibility. Quality Attribute: Application Modifiability The Modifiability quality attribute refers to how easy it changing the system in the future will be. This to me is a very open-ended attribute because a business could decide to transform a Point of Sale (POS) system in to a Lead Tracking system overnight. (Yes, this did actually happen to me) In order for SAAM to be properly applied for checking this attribute specific hypothetical case studies need to be created and review for the modifiability attribute due to the fact that various scenarios would return various results based on the amount of changes. In the case of the POS change out a payment gateway or adding an additional payment would have scored very high in comparison to changing the system over to a lead management system. I personally would evaluate this quality attribute based on the S.O.I.L.D Principles of software design. I have found from my experience the use of S.O.I.L.D in software design allows for the adoption of changes within a system. Quality Attribute: Application Robustness The Robustness quality attribute refers to how an application handles the unexpected. The unexpected can be defined but is not limited to anything not anticipated in the originating design of the system. For example: Bad Data, Limited to no network connectivity, invalid permissions, or any unexpected application exceptions. I would personally evaluate this quality attribute based on how the system handled the exceptions. Robustness Considerations Did the system stop or did it handle the unexpected error? Did the system log the unexpected error for future debugging? What message did the user receive about the error? Quality Attribute: Application Portability The Portability quality attribute refers to the ease of porting an application to run in a new operating system or device. For example, It is much easier to alter an ASP.net website to be accessible by a PC, Mac, IPhone, Android Phone, Mini PC, or Table in comparison to desktop application written in VB.net because a lot more work would be involved to get the desktop app to the point where it would be viable to port the application over to the various environments and devices. I would personally evaluate this quality attribute based on each new environment for which the hypothetical case study identifies. I would pay particular attention to the following items. Portability Considerations Hardware Dependencies Operating System Dependencies Data Source Dependencies Network Dependencies and Availabilities  Quality Attribute: Application Extensibility The Extensibility quality attribute refers to the ease of adding new features to an existing application without impacting existing functionality. I would personally evaluate this quality attribute based on each new environment for the following Extensibility  Considerations Hard coded Variables versus Configurable variables Application Documentation (External Documents and Codebase Documentation.) The use of Solid Design Principles

  • Creating a Linux cluster/cloud to act as a server.

    - by Kavon Farvardin
    I have about four or five machines in the Pentium 3-4 era and I'm interested in creating a Linux server comprised of these machines. The server's main purposes would be to host several low-medium traffic websites/services (voice and game), and share terabytes of data on a local network. I could probably throw together one modern computer as a server and call it a day, but I'm interested in using these machines to do it instead. Where would I get started in this cluster/cloud setup?

  • Alternatives to Pessimistic Locking in Cluster Applications

    - by amphibient
    I am researching alternatives to database-level pessimistic locking to achieve transaction isolation in a cluster of Java applications going against the same database. Synchronizing concurrent access in the application tier is clearly not a solution in the present configuration because the same database transaction can be invoked from multiple JVMs concurrently. Currently, we are subject to occasional race conditions which, due to the optimistic locking we have in place via Hibernate, cause a StaleObjectStateException exception and data loss. I have a moderately large transaction within the scope of my refactoring project. Let's describe it as updating one top-level table row and then making various related inserts and/or updates to several of its child entities. I would like to insure exclusive access to the top-level table row and all of the children to be affected but I would like to stay away from pessimistic locking at the database level for performance reasons mostly. We use Hibernate for ORM. Does it make sense to start a single (perhaps synchronous) message queue application into which this method could be moved to insure synchronized access as opposed to each cluster node using its own, which is a clear race condition hazard? I am mentioning this approach even though I am not confident in it because both the top-level table row and its children could also be updated from other system calls, not just the mentioned transaction. So I am seeking to design a solution where the top-level table row and its children will all somehow be pseudo-locked (exclusive transaction isolation) but at the application and not the database level. I am open to ideas and suggestions, I understand this is not a very cut and dried challenge.

  • c++ ide & tools with clang integration

    - by lurscher
    recently i read this blog about google integrating clang parser into their code analysis tools This is something in which c++ is at least a decade behind other languages like java, but now that llvm-clang is almost c++ iso-ready, i think its possible for c++ code analysis tools to begin using the c++ parser effectively, since it has been designed from the ground up precisely for this so i'm wondering if there are existing open source or known commercial projects taking this path, integrating with clang to provide higher-level analysis tools?
