• SQL Injection - some sense at last!

  - by TATWORTH

  I see various articles that proclaim means to guard against SQL injection. As individual steps they are of use but since they were often proclaimed as "the solution" they were potentially misleading. At http://www.simple-talk.com/sql/learn-sql-server/sql-injection-defense-in-depth/ there is an article entitled "SQL Injection: Defense in Depth" - this article argues what I have argued myself. Remember that however low-grade the information on your web site is, if your site is hacked, the public may percive the hacking as your most sensitive information was exposed.

I am looking mostly for an integrated solution and not in the line of awk+gnuplot scripts.

• JavaOne 2012 Call for Papers

  - by Tori Wieldt

  JavaOne 2012 is happening Sept. 30-Oct 4 in San Francisco. The Call For Papers for this conference is now open. Java Evangelist Arun Gupta, who was on one of the selection committees and will be again this year, provided some great tips for submission (and a peek into the submission process): JavaOne is a technology-focused conference so any product, marketing or seemingly marketish talk are put at the bottom of the list. Oracle Open World and Oracle Develop are better options for submitting product specific talks. Make your title catchy. Remember the attendees are more likely to read the abstract if they like the title. We try our best to recategorize the talk to a different track if it needs to but please ensure that you are filing in the right track to have all the right eyeballs looking at it. Also, it does not hurt marking an alternate track if your talk meets the criteria. Make sure to coordinate within your team before the submission - multiple sessions from the same team or company does not ensure that the best speaker is picked. In such case we rely upon your "google presence" and/or review committee's prior knowledge of the speaker. The reviewers may not know you or your product at all and you get 750 characters to pitch your idea. Make sure to use all of them, to the last 750th character. Make sure to read your abstract multiple times to ensure that you are giving all the relevant information ? Think through your presentation and see if you are leaving out any important aspects. Also look if the abstract has any redundant information that will not required by the reviewers. There are additional sections that allow you to share information about the speaker and the presentation summary. Use them to blow the horn about yourself and any other relevant details. Please don't say "call me at xxx-xxx-xxxx to find out the details." :-) The tracks this year are: Core Java Platform Development Tools and Techniques Emerging Langauges on the JVM Enterprise Services Architectures and the Cloud Java EE Web Profile and Platform Technologies Java ME, Java Card, Embedded, and Devices Java FX and Rich User Experiences IMPORTANT: Submit your proposal as soon as possible, the the Call for Papers closes April 9th, a mere three weeks away!  Follow these channels to get the latest news about #JavaOne 2012.  originally posted on blogs.oracle.com/javaone

• Should I be looking for an alternative to Zen Cart as my business grows?

  - by MarkS

  I created a business website for a family business which is growing. It's my family, and I'm a software developer, but I don't want to rebuild the wheels or be a shopping cart programmer. For this business, I need the web store to "just work", but... it gets complicated... There are two parts of this business website. One of them is driven by Wordpress and I use the awesome Thesis theme. This is modern, flexible, and saves me a lot of time from doing custom coding and styling. I couldn't be more pleased with this arrangement. The other part of the site is a Zen Cart store. It's administration and it's flexibility is frustrating and archaic Web 1.0. For the past few years, I keep hearing that the developers are working on a 2.0 version of Zen Cart, but they haven't communicated anything significant in the past few years other than to say, "When it's ready, we'll let you know." What I'm looking for in a cart, I would need to install 6-10 additional mods, and would need to do a lot of custom coding. I'm now willing to pay for a top-notch e-commerce solution for a small business that we can grow up into a larger business over time. Requirements: Extremely flexible shipping that let's us set up rules per product/category, tables of rates, calculated rates, max package weighs, etc. (flexibility like that available with CEON Advance Shipping Module for Zen Cart Coupons and gift certificates Manual order entry for phone orders Multi-channel support (We also sell on Amazon, eBay, use Google Base and we want to maintain one set of inventory and have it kept current) Decent SEO features Reviews and star-ratings on products Easy social networking features for sharing, following, liking, etc) Easy integration with AdWords and analytics tracking Modern and very usable product and store administration (Like I was saying, I'm spoiled by Wordpress and Thesis) At the end of the day, I don't care if it's a hosted solution or if I have to host it myself. I just want something that is going to stay up-to-date, regularly be maintained and improved, and if I have to update it, things like the one-click update present in Wordpress is something it has to have. Professional Webmasters, if you had to run a store / website, but you had to spend your time focusing on your sales and marketing efforts rather than diffing php files and copying and tweaking them to change even the slightest details of your site, what would you choose?

• ASP.NET MVC 3 Hosting :: How to Upgrade ASP.NET MVC 2 Project to ASP.NET MVC 3

  - by mbridge

  ASP.NET MVC 3 can be installed side by side with ASP.NET MVC 2 on the same computer, which gives you flexibility in choosing when to upgrade an ASP.NET MVC 2 application to ASP.NET MVC 3. The simplest way to upgrade is to create a new ASP.NET MVC 3 project and copy all the views, controllers, code, and content files from the existing MVC 2 project to the new project and then to update the assembly references in the new project to match the old project. If you have made changes to the Web.config file in the MVC 2 project, you must also merge those changes with the Web.config file in the MVC 3 project. To manually upgrade an existing ASP.NET MVC 2 application to version 3, do the following: 1. In both Web.config files in the MVC 3 project, globally search and replace the MVC version. Find the following: System.Web.Mvc, Version=2.0.0.0 Replace it with the following System.Web.Mvc, Version=3.0.0.0 There are three changes in the root Web.config and four in the Views\Web.config file. 2. In Solution Explorer, delete the reference to System.Web.Mvc (which points to the version 2 DLL). Then add a reference to System.Web.Mvc (v3.0.0.0). 3. In Solution Explorer, right-click the project name and then select Unload Project. Then right-click again and select Edit ProjectName.csproj. 4. Locate the ProjectTypeGuids element and replace {F85E285D-A4E0-4152-9332-AB1D724D3325} with {E53F8FEA-EAE0-44A6-8774-FFD645390401}. 5. Save the changes and then right-click the project and select Reload Project. 6. If the project references any third-party libraries that are compiled using ASP.NET MVC 2, add the following highlighted bindingRedirect element to the Web.config file in the application root under the configuration section: <runtime>   <assemblyBinding >     <dependentAssembly>       <assemblyIdentity name="System.Web.Mvc"           publicKeyToken="31bf3856ad364e35"/>       <bindingRedirect oldVersion="2.0.0.0" newVersion="3.0.0.0"/>     </dependentAssembly>   </assemblyBinding> </runtime> Another ASP.NET MVC 3 article: - Rolling with Razor in MVC v3 Preview - Deploying ASP.NET MVC 3 web application to server where ASP.NET MVC 3 is not installed - RenderAction with ASP.NET MVC 3 Sessionless Controllers

• Attribute Overwriting in MDX

  - by Marco Russo (SQLBI)

  Jeffrey Wang wrote a great blog post about attribute overwriting in MDX that is very clear and full of helpful pictures to show what happens when you write an MDX statement that writes into your multidimensional space. This is very common in an MDX Script and if you tried to customize the DateTool solution you probably experienced how hard this concept can be. The point is not that MDX is hard, is that a model based on multiple hierarchies in a dimension (and each attribute is a hierarchy by default!)...(read more)

  As the title above mentions, i've some issues with wireless connection on both ubuntu 11.10 and 12.04. I've installed the latest drivers (Atheros AR928x), like "compact-wireless package" on several machines including ubuntu 11.10. The connection still too slow. My internet connection is 100 mb so, using WLAN connection, it should give me 70/80 mb of signal... instead of the 40/50 mb that i'm experience right now.. Do you have a solution to increase the signal?

• Why lock statements don't scale

  - by Alex.Davies

  We are going to have to stop using lock statements one day. Just like we had to stop using goto statements. The problem is similar, they're pretty easy to follow in small programs, but code with locks isn't composable. That means that small pieces of program that work in isolation can't necessarily be put together and work together. Of course actors scale fine :) Why lock statements don't scale as software gets bigger Deadlocks. You have a program with lots of threads picking up lots of locks. You already know that if two of your threads both try to pick up a lock that the other already has, they will deadlock. Your program will come to a grinding halt, and there will be fire and brimstone. "Easy!" you say, "Just make sure all the threads pick up the locks in the same order." Yes, that works. But you've broken composability. Now, to add a new lock to your code, you have to consider all the other locks already in your code and check that they are taken in the right order. Algorithm buffs will have noticed this approach means it takes quadratic time to write a program. That's bad. Why lock statements don't scale as hardware gets bigger Memory bus contention There's another headache, one that most programmers don't usually need to think about, but is going to bite us in a big way in a few years. Locking needs exclusive use of the entire system's memory bus while taking out the lock. That's not too bad for a single or dual-core system, but already for quad-core systems it's a pretty large overhead. Have a look at this blog about the .NET 4 ThreadPool for some numbers and a weird analogy (see the author's comment). Not too bad yet, but I'm scared my 1000 core machine of the future is going to go slower than my machine today! I don't know the answer to this problem yet. Maybe some kind of per-core work queue system with hierarchical work stealing. Definitely hardware support. But what I do know is that using locks specifically prevents any solution to this. We should be abstracting our code away from the details of locks as soon as possible, so we can swap in whatever solution arrives when it does. NAct uses locks at the moment. But my advice is that you code using actors (which do scale well as software gets bigger). And when there's a better way of implementing actors that'll scale well as hardware gets bigger, only NAct needs to work out how to use it, and your program will go fast on it's own.

• EXT2 on Windows - a Year later

  <b>Matthew Casperson's Hubfolio:</b> "Traditionally the solution is a common partition formatted with FAT32, but instead of making Linux do the hard work of interacting with Windows, I thought I would try it the other way around. This is how I found myself testing both Ext2Fsd and Ext IFS For Windows."
