  • Ignore case in Python strings

    - by Paul Oyster
    What is the easiest way to compare strings in Python, ignoring case? Of course one can do (str1.lower() <= str2.lower()), etc., but this created two additional temporary strings (with the obvious alloc/g-c overheads). I guess I'm looking for an equivalent to C's stricmp(). [Some more context requested, so I'll demonstrate with a trivial example:] Suppose you want to sort a looong list of strings. You simply do theList.sort(). This is O(n * log(n)) string comparisons and no memory management (since all strings and list elements are some sort of smart pointers). You are happy. Now, you want to do the same, but ignore the case (let's simplify and say all strings are ascii, so locale issues can be ignored). You can do theList.sort(key=lambda s: s.lower()), but then you cause two new allocations per comparison, plus burden the garbage-collector with the duplicated (lowered) strings. Each such memory-management noise is orders-of-magnitude slower than simple string comparison. Now, with an in-place stricmp()-like function, you do: theList.sort(cmp=stricmp) and it is as fast and as memory-friendly as theList.sort(). You are happy again. The problem is any Python-based case-insensitive comparison involves implicit string duplications, so I was expecting to find a C-based comparisons (maybe in module string). Could not find anything like that, hence the question here. (Hope this clarifies the question).

  • Delphi Performance: Case Versus If

    - by Andreas Rejbrand
    I guess there might be some overlapping with previous SO questions, but I could not find a Delphi-specific question on this topic. Suppose that you want to check if an unsigned 32-bit integer variable "MyAction" is equal to any of the constants ACTION1, ACTION2, ... ACTIONn, where n is - say 1000. I guess that, besides being more elegant, case MyAction of ACTION1: {code}; ACTION2: {code}; ... ACTIONn: {code}; end; if much faster than if MyAction = ACTION1 then // code else if MyAction = ACTION2 then // code ... else if MyAction = ACTIONn then // code; I guess that the if variant takes time O(n) to complete (i.e. to find the right action) if the right action ACTIONi has a high value of i, whereas the case variant takes a lot less time (O(1)?). Am I correct that switch is much faster? Am I correct that the time required to find the right action in the switch case actually is independent of n? I.e. is it true that it does not really take any longer to check a million cases than to check 10 cases? How, exactly, does this work?

  • jQuery Tools - Range Input with Mousewheel support

    - by pspahn
    I've got a nice looking horizontal scroller that uses the Range Input feature of jQ Tools. Mouse wheel scrolling support would be awesome, and I'm sure it can work, just not sure how to get it set up. I've got the generic setup: var scroll = jQuery('#scroll'); jQuery(':range').rangeinput({ speed: 0, progress: true, onSlide: function(ev, step) { scroll.css({left: -step}); }, change: function(e, i) { scroll.animate({left: -i}, "fast"); } }); The doc page ( http://jquerytools.org/documentation/toolbox/mousewheel.html ) for mousewheel gives an example: $("#myelement").mousewheel(function(event, delta) { }); But I'm not sure how this hooks in. Other tools in the package simply allow the option: mousewheel: true Unfortunately that doesn't work on range input. Any advice appreciated. Thank you.

  • Making a Case For The Command Line

    - by Jesse Taber
    Originally posted on: http://geekswithblogs.net/GruffCode/archive/2013/06/30/making-a-case-for-the-command-line.aspxI have had an idea percolating in the back of my mind for over a year now that I’ve just recently started to implement. This idea relates to building out “internal tools” to ease the maintenance and on-going support of a software system. The system that I currently work on is (mostly) web-based, so we traditionally we have built these internal tools in the form of pages within the app that are only accessible by our developers and support personnel. These pages allow us to perform tasks within the system that, for one reason or another, we don’t want to let our end users perform (e.g. mass create/update/delete operations on data, flipping switches that turn paid modules of the system on or off, etc). When we try to build new tools like this we often struggle with the level of effort required to build them. Effort Required Creating a whole new page in an existing web application can be a fairly large undertaking. You need to create the page and ensure it will have a layout that is consistent with the other pages in the app. You need to decide what types of input controls need to go onto the page. You need to ensure that everything uses the same style as the rest of the site. You need to figure out what the text on the page should say. Then, when you figure out that you forgot about an input that should really be present you might have to go back and re-work the entire thing. Oh, and in addition to all of that, you still have to, you know, write the code that actually performs the task. Everything other than the code that performs the task at hand is just overhead. We don’t need a fancy date picker control in a nicely styled page for the vast majority of our internal tools. We don’t even really need a page, for that matter. We just need a way to issue a command to the application and have it, in turn, execute the code that we’ve written to accomplish a given task. All we really need is a simple console application! Plumbing Problems A former co-worker of mine, John Sonmez, always advocated the Unix philosophy for building internal tools: start with something that runs at the command line, and then build a UI on top of that if you need to. John’s idea has a lot of merit, and we tried building out some internal tools as simple Console applications. Unfortunately, this was often easier said that done. Doing a “File –> New Project” to build out a tool for a mature system can be pretty daunting because that new project is totally empty.  In our case, the web application code had a lot of of “plumbing” built in: it managed authentication and authorization, it handled database connection management for our multi-tenanted architecture, it managed all of the context that needs to follow a user around the application such as their timezone and regional/language settings. In addition, the configuration file for the web application  (a web.config in our case because this is an ASP .NET application) is large and would need to be reproduced into a similar configuration file for a Console application. While most of these problems are could be solved pretty easily with some refactoring of the codebase, building Console applications for internal tools still potentially suffers from one pretty big drawback: you’d have to execute them on a machine with network access to all of the needed resources. Obviously, our web servers can easily communicate the the database servers and can publish messages to our service bus, but the same is not true for all of our developer and support personnel workstations. We could have everyone run these tools remotely via RDP or SSH, but that’s a bit cumbersome and certainly a lot less convenient than having the tools built into the web application that is so easily accessible. Mix and Match So we need a way to build tools that are easily accessible via the web application but also don’t require the overhead of creating a user interface. This is where my idea comes into play: why not just build a command line interface into the web application? If it’s part of the web application we get all of the plumbing that comes along with that code, and we’re executing everything on the web servers which means we’ll have access to any external resources that we might need. Rather than having to incur the overhead of creating a brand new page for each tool that we want to build, we can create one new page that simply accepts a command in text form and executes it as a request on the web server. In this way, we can focus on writing the code to accomplish the task. If the tool ends up being heavily used, then (and only then) should we consider spending the time to build a better user experience around it. To be clear, I’m not trying to downplay the importance of building great user experiences into your system; we should all strive to provide the best UX possible to our end users. I’m only advocating this sort of bare-bones interface for internal consumption by the technical staff that builds and supports the software. This command line interface should be the “back end” to a highly polished and eye-pleasing public face. Implementation As I mentioned at the beginning of this post, this is an idea that I’ve had for awhile but have only recently started building out. I’ve outlined some general guidelines and design goals for this effort as follows: Text in, text out: In the interest of keeping things as simple as possible, I want this interface to be purely text-based. Users will submit commands as plain text, and the application will provide responses in plain text. Obviously this text will be “wrapped” within the context of HTTP requests and responses, but I don’t want to have to think about HTML or CSS when taking input from the user or displaying responses back to the user. Task-oriented code only: After building the initial “harness” for this interface, the only code that should need to be written to create a new internal tool should be code that is expressly needed to accomplish the task that the tool is intended to support. If we want to encourage and enable ourselves to build good tooling, we need to lower the barriers to entry as much as possible. Built-in documentation: One of the great things about most command line utilities is the ‘help’ switch that provides usage guidelines and details about the arguments that the utility accepts. Our web-based command line utility should allow us to build the documentation for these tools directly into the code of the tools themselves. I finally started trying to implement this idea when I heard about a fantastic open-source library called CLAP (Command Line Auto Parser) that lets me meet the guidelines outlined above. CLAP lets you define classes with public methods that can be easily invoked from the command line. Here’s a quick example of the code that would be needed to create a new tool to do something within your system: 1: public class CustomerTools 2: { 3: [Verb] 4: public void UpdateName(int customerId, string firstName, string lastName) 5: { 6: //invoke internal services/domain objects/hwatever to perform update 7: } 8: } This is just a regular class with a single public method (though you could have as many methods as you want). The method is decorated with the ‘Verb’ attribute that tells the CLAP library that it is a method that can be invoked from the command line. Here is how you would invoke that code: Parser.Run(args, new CustomerTools()); Note that ‘args’ is just a string[] that would normally be passed passed in from the static Main method of a Console application. Also, CLAP allows you to pass in multiple classes that define [Verb] methods so you can opt to organize the code that CLAP will invoke in any way that you like. You can invoke this code from a command line application like this: SomeExe UpdateName -customerId:123 -firstName:Jesse -lastName:Taber ‘SomeExe’ in this example just represents the name of .exe that is would be created from our Console application. CLAP then interprets the arguments passed in order to find the method that should be invoked and automatically parses out the parameters that need to be passed in. After a quick spike, I’ve found that invoking the ‘Parser’ class can be done from within the context of a web application just as easily as it can from within the ‘Main’ method entry point of a Console application. There are, however, a few sticking points that I’m working around: Splitting arguments into the ‘args’ array like the command line: When you invoke a standard .NET console application you get the arguments that were passed in by the user split into a handy array (this is the ‘args’ parameter referenced above). Generally speaking they get split by whitespace, but it’s also clever enough to handle things like ignoring whitespace in a phrase that is surrounded by quotes. We’ll need to re-create this logic within our web application so that we can give the ‘args’ value to CLAP just like a console application would. Providing a response to the user: If you were writing a console application, you might just use Console.WriteLine to provide responses to the user as to the progress and eventual outcome of the command. We can’t use Console.WriteLine within a web application, so I’ll need to find another way to provide feedback to the user. Preferably this approach would allow me to use the same handler classes from both a Console application and a web application, so some kind of strategy pattern will likely emerge from this effort. Submitting files: Often an internal tool needs to support doing some kind of operation in bulk, and the easiest way to submit the data needed to support the bulk operation is in a file. Getting the file uploaded and available to the CLAP handler classes will take a little bit of effort. Mimicking the console experience: This isn’t really a requirement so much as a “nice to have”. To start out, the command-line interface in the web application will probably be a single ‘textarea’ control with a button to submit the contents to a handler that will pass it along to CLAP to be parsed and run. I think it would be interesting to use some javascript and CSS trickery to change that page into something with more of a “shell” interface look and feel. I’ll be blogging more about this effort in the future and will include some code snippets (or maybe even a full blown example app) as I progress. I also think that I’ll probably end up either submitting some pull requests to the CLAP project or possibly forking/wrapping it into a more web-friendly package and open sourcing that.

  • Need help in determing what, if any, tools can be used to create a free Flash game

    - by ReaperOscuro
    Yes I proudly -and sadly- declare that I am a complete nincompoop when it comes to Flash, and I have been fishing around the big wide web for information. The reason for this is that I have been contracted to create a game(s) for a website -the usual flash-based games caveat. Please I do not mean things like by those gaming generator websites, I mean small yet professional games- but the caveat, as always, is that impossible dream: it needs to be done all for free. The budget...well imagine it as not there. Annoyingly is that I am a game designer yes, but with a ridiculously tight deadline I haven't got much time to re-learn (ah the heady days of programming at uni) everything by the end of March, so I'd like to ask some people who know their stuff rather than keep looking at a gazillion different things. This is my understanding: with the flash sdk you can create a game, albeit you need to be pretty programming savvy. FlashDevelop helps there -yet I am not entirely sure how. Yet even FD says to use Flash for the animation/graphics. Yes its undeniably powerful but as I said there is the unattainable demand of no money. The million dollar question: what, if any, tools can I use to create a free flash game?

  • How Many Google +1's Does a Website need in order for Google WebMaster's Tools to Show Characteristics

    - by Asaph
    I have added the Google +1 Button to my website and discovered the new Social Activity section in Google WebMaster's Tools. Apparently, one of the interesting things you can learn about your audience is demographic data. But in GWT, the Social Activity Audience section for my site (currently 82 +1's), says the following: Your site doesn’t have enough +1's yet to show characteristics But I'm not sure how many +1's is enough. Google's official help page for the Audience section offers little insight: The Audience page displays information about people who have +1'd your pages, including the total number of unique users, their location, and their age and gender. All information is anonymized; Google doesn't share personal information about people who have +1’d your pages. To protect privacy, Google won't display age, gender, or location data unless a certain minimum number of people have +1'd your content. But what is that "certain minimum number"? I've tried Googling this but all I could find to date was this page which doesn't answer the question. So how many +1's does a site need before GWT will show me audience demographic characteristics?

  • How can I decrease relevancy of Creative Commons footer text? (In Google Webmaster Tools)

    - by anonymous coward
    I know that I may just have to link the image to make this happen, but I figured it was worth asking, just in case there's some other semantic markup or tips I could use... I have a site that uses the textual Creative Commons blurb in the footer. The markup is like so: <div class="footer"> <!-- snip --> <!-- Creative Commons License --> <a rel="license" href="http://creativecommons.org/licenses/by-nc-sa/3.0/us/"><img alt="Creative Commons License" style="border-width:0" src="http://i.creativecommons.org/l/by-nc-sa/3.0/us/80x15.png" /></a><br />This work by <a xmlns:cc="http://creativecommons.org/ns#" href="http://www.xmemphisx.com/" property="cc:attributionName" rel="cc:attributionURL">xMEMPHISx.com</a> is licensed under a <a rel="license" href="http://creativecommons.org/licenses/by-nc-sa/3.0/us/">Creative Commons Attribution-Noncommercial-Share Alike 3.0 United States License</a>. <!-- /Creative Commons License --> </div> Within Google Webmaster Tools, the list of relevant keywords is heavily saturated with the text from that blurb. For instance, 50% of my top-ten most relevant keywords (including the site name): [site name] license [keyword] commons creative [keyword] alike [keyword] attribution [keyword] I have not done any extensive testing to find out rather or not this list even matters, and so far this doesn't impact performance in any way. The site is well designed for humans, and it is as findable as it needs to be at the moment. But, out of mostly curiosity: Do you have any tips for decreasing the relevancy of the text from the Creative Commons footer blurb?

  • How to Fix this specific Google "Fetch as Googlebot" error appearing on my Webmaster Tools?

    - by UXdesigner
    Good day, I'm currently finding out why I have lost all of my website's rank in google. I don't even appear in google results by the domain. But other sites do link me and they appear in the google results. I think it's all about leaving my site two months alone and finding out I had 20k in comment spam, which I completely deleted and fixed with filters and adding a new Disqus comment service. Thing is, I added my site to Google Webmaster Tools and I'm finding out several awful things. For example, when I click in Google Fetch As GoogleBot. I receive this error message below in response to my request. And I don't even know what's the real problem and how to fix it. I simply don't get it. This is what appears: Date: Wednesday, July 20, 2011 9:43:35 AM PDT Googlebot Type: Web Download Time (in milliseconds): 55 HTTP/1.1 403 Forbidden Date: Wed, 20 Jul 2011 16:43:36 GMT Server: Apache Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 248 Keep-Alive: timeout=2, max=100 Connection: Keep-Alive Content-Type: text/html; charset=iso-8859-1 403 Forbidden Forbidden You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. Do you guys know anything about this problem ? I need to have Google crawl my site again. I used to have a really nice google result in the past three years. Now, there's nothing. thanks,

  • Why won't Webmaster Tools let me set a preferred domain? (says to verify, but it should already be)

    - by Su'
    I've got a domain that I apparently forgot to set a preferred domain for, so I just tried to do it. Webmaster Tools instead popped up a little box: Part of the process of setting a preferred domain is to verify that you own http://www.example.com/. Please verify http://www.example.com/. I'm running into some problems following these instructions: As far as I can tell I already did verify sometime in the past. There's a TXT DNS record with the gibberish Google tells you to set for it that I couldn't have come up with myself. …and nothing is telling me this information is bad. So let's assume the site is somehow not actually verified. All the various methods' instructions start with "click the Manage Site button next to the site you want, and then click Verify this site." That button doesn't even exist on my screens. (It presumably goes away when you successfully verify?) Those instructions were all updated pretty recently, and the DNS one in particular just a couple weeks ago so it seems a bit unlikely they're inaccurate. I am not using Apps, and won't be, so can't try out the verification through there. Note that I also have another domain that I have not done any verification for which is showing the same behavior(no such button, being told to verify when it seems impossible etc.) so something appears to just be broken. I already have a no-www process in place server-side, so we can skip that. I'm just trying to get the box checked off in GWT. If I don't get any resolution, I'll eventually scrap the TXT record and see if the site gets un-verified(or whatever since it thinks it isn't), and see if I can just restart the process. It's not urgent so I'm just trying to figure out if I've gone blind to something or what. Did the button move?

    I recently put together a simple public website created with ASP.NET for my company at Superexpert.com. I was surprised by the number of free tools that I ended up using to put together the website. Therefore, I thought it would be interesting to create a list of essential tools for building ASP.NET websites. These tools work equally well with both ASP.NET Web Forms and ASP.NET MVC. Performance Tools After reading Steve Souders two (very excellent) books on front-end website performance High Performance Web Sites and Even Faster Web Sites, I have been super sensitive to front-end website performance. According to Souders’ Performance Golden Rule: “Optimize front-end performance first, that's where 80% or more of the end-user response time is spent” You can use the tools below to reduce the size of the images, JavaScript files, and CSS files used by an ASP.NET application. 1. Sprite and Image Optimization Framework CSS sprites were first described in an article written for A List Apart entitled CSS sprites: Image Slicing’s Kiss of Death. When you use sprites, you combine multiple images used by a website into a single image. Next, you use CSS trickery to display particular sub-images from the combined image in a webpage. The primary advantage of sprites is that they reduce the number of requests required to display a webpage. Requesting a single large image is faster than requesting multiple small images. In general, the more resources – images, JavaScript files, CSS files – that must be moved across the wire, the slower your website. However, most people avoid using sprites because they require a lot of work. You need to combine all of the images and write just the right CSS rules to display the sub-images. The Microsoft Sprite and Image Optimization Framework enables you to avoid all of this work. The framework combines the images for you automatically. Furthermore, the framework includes an ASP.NET Web Forms control and an ASP.NET MVC helper that makes it easy to display the sub-images. You can download the Sprite and Image Optimization Framework from CodePlex at http://aspnet.codeplex.com/releases/view/50869. The Sprite and Image Optimization Framework was written by Morgan McClean who worked in the office next to mine at Microsoft. Morgan was a scary smart Intern from Canada and we discussed the Framework while he was building it (I was really excited to learn that he was working on it). Morgan added some great advanced features to this framework. For example, the Sprite and Image Optimization Framework supports something called image inlining. When you use image inlining, the actual image is stored in the CSS file. Here’s an example of what image inlining looks like: .Home_StephenWalther_small-jpg { width:75px; height:100px; background: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAEsAAABkCAIAAABB1lpeAAAAB GdBTUEAALGOfPtRkwAAACBjSFJNAACHDwAAjA8AAP1SAACBQAAAfXkAAOmLAAA85QAAGcxzPIV3AAAKL s+zNfREAAAAASUVORK5CYII=) no-repeat 0% 0%; } The actual image (in this case a picture of me that is displayed on the home page of the Superexpert.com website) is stored in the CSS file. If you visit the Superexpert.com website then very few separate images are downloaded. For example, all of the images with a red border in the screenshot below take advantage of CSS sprites: Unfortunately, there are some significant Gotchas that you need to be aware of when using the Sprite and Image Optimization Framework. There are workarounds for these Gotchas. I plan to write about these Gotchas and workarounds in a future blog entry. 2. Microsoft Ajax Minifier Whenever possible you should combine, minify, compress, and cache with a far future header all of your JavaScript and CSS files. The Microsoft Ajax Minifier makes it easy to minify JavaScript and CSS files. Don’t confuse minification and compression. You need to do both. According to Souders, you can reduce the size of a JavaScript file by an additional 20% (on average) by minifying a JavaScript file after you compress the file. When you minify a JavaScript or CSS file, you use various tricks to reduce the size of the file before you compress the file. For example, you can minify a JavaScript file by replacing long JavaScript variables names with short variables names and removing unnecessary white space and comments. You can minify a CSS file by doing such things as replacing long color names such as #ffffff with shorter equivalents such as #fff. The Microsoft Ajax Minifier was created by Microsoft employee Ron Logan. Internally, this tool was being used by several large Microsoft websites. We also used the tool heavily on the ASP.NET team. I convinced Ron to publish the tool on CodePlex so that everyone in the world could take advantage of it. You can download the tool from the ASP.NET Ajax website and read documentation for the tool here. I created the installer for the Microsoft Ajax Minifier. When creating the installer, I also created a Visual Studio build task to make it easy to minify all of your JavaScript and CSS files whenever you do a build within Visual Studio automatically. Read the Ajax Minifier Quick Start to learn how to configure the build task. 3. ySlow The ySlow tool is a free add-on for Firefox created by Yahoo that enables you to test the front-end of your website. For example, here are the current test results for the Superexpert.com website: The Superexpert.com website has an overall score of B (not perfect but not bad). The ySlow tool is not perfect. For example, the Superexpert.com website received a failing grade of F for not using a Content Delivery Network even though the website using the Microsoft Ajax Content Delivery Network for JavaScript files such as jQuery. Uptime After publishing a website live to the world, you want to ensure that the website does not encounter any issues and that it stays live. I use the following tools to monitor the Superexpert.com website now that it is live. 4. ELMAH ELMAH stands for Error Logging Modules and Handlers for ASP.NET. ELMAH enables you to record any errors that happen at your website so you can review them in the future. You can download ELMAH for free from the ELMAH project website. ELMAH works great with both ASP.NET Web Forms and ASP.NET MVC. You can configure ELMAH to store errors in a number of different stores including XML files, the Event Log, an Access database, a SQL database, an Oracle database, or in computer RAM. You also can configure ELMAH to email error messages to you when they happen. By default, you can access ELMAH by requesting the elmah.axd page from a website with ELMAH installed. Here’s what the elmah page looks like from the Superexpert.com website (this page is password-protected because secret information can be revealed in an error message): If you click on a particular error message, you can view the original Yellow Screen ASP.NET error message (even when the error message was never displayed to the actual user). I installed ELMAH by taking advantage of the new package manager for ASP.NET named NuGet (originally named NuPack). You can read the details about NuGet in the following blog entry by Scott Guthrie. You can download NuGet from CodePlex. 5. Pingdom I use Pingdom to verify that the Superexpert.com website is always up. You can sign up for Pingdom by visiting Pingdom.com. You can use Pingdom to monitor a single website for free. At the Pingdom website, you configure the frequency that your website gets pinged. I verify that the Superexpert.com website is up every 5 minutes. I have the Pingdom service verify that it can retrieve the string “Contact Us” from the website homepage. If your website goes down, you can configure Pingdom so that it sends an email, Twitter, SMS, or iPhone alert. I use the Pingdom iPhone app which looks like this: 6. Host Tracker If your website does go down then you need some way of determining whether it is a problem with your local network or if your website is down for everyone. I use a website named Host-Tracker.com to check how badly a website is down. Here’s what the Host-Tracker website displays for the Superexpert.com website when the website can be successfully pinged from everywhere in the world: Notice that Host-Tracker pinged the Superexpert.com website from 68 locations including Roubaix, France and Scranton, PA. Debugging I mean debugging in the broadest possible sense. I use the following tools when building a website to verify that I have not made a mistake. 7. HTML Spell Checker Why doesn’t Visual Studio have a built-in spell checker? Don’t know – I’ve always found this mysterious. Fortunately, however, a former member of the ASP.NET team wrote a free spell checker that you can use with your ASP.NET pages. I find a spell checker indispensible. It is easy to delude yourself that you are capable of perfect spelling. I’m always super embarrassed when I actually run the spell checking tool and discover all of my spelling mistakes. The fastest way to add the HTML Spell Checker extension to Visual Studio is to select the menu option Tools, Extension Manager within Visual Studio. Click on Online Gallery and search for HTML Spell Checker: 8. IIS SEO Toolkit If people cannot find your website through Google then you should not even bother to create it. Microsoft has a great extension for IIS named the IIS Search Engine Optimization Toolkit that you can use to identify issue with your website that would hurt its page rank. You also can use this tool to quickly create a sitemap for your website that you can submit to Google or Bing. You can even generate the sitemap for an ASP.NET MVC website. Here’s what the report overview for the Superexpert.com website looks like: Notice that the Sueprexpert.com website had plenty of violations. For example, there are 65 cases in which a page has a broken hyperlink. You can drill into these violations to identity the exact page and location where these violations occur. 9. LinqPad If your ASP.NET website accesses a database then you should be using LINQ to Entities with the Entity Framework. Using LINQ involves some magic. LINQ queries written in C# get converted into SQL queries for you. If you are not careful about how you write your LINQ queries, you could unintentionally build a really badly performing website. LinqPad is a free tool that enables you to experiment with your LINQ queries. It even works with Microsoft SQL CE 4 and Azure. You can use LinqPad to execute a LINQ to Entities query and see the results. You also can use it to see the resulting SQL that gets executed against the database: 10. .NET Reflector I use .NET Reflector daily. The .NET Reflector tool enables you to take any assembly and disassemble the assembly into C# or VB.NET code. You can use .NET Reflector to see the “Source Code” of an assembly even when you do not have the actual source code. You can download a free version of .NET Reflector from the Redgate website. I use .NET Reflector primarily to help me understand what code is doing internally. For example, I used .NET Reflector with the Sprite and Image Optimization Framework to better understand how the MVC Image helper works. Here’s part of the disassembled code from the Image helper class: Summary In this blog entry, I’ve discussed several of the tools that I used to create the Superexpert.com website. These are tools that I use to improve the performance, improve the SEO, verify the uptime, or debug the Superexpert.com website. All of the tools discussed in this blog entry are free. Furthermore, all of these tools work with both ASP.NET Web Forms and ASP.NET MVC. Let me know if there are any tools that you use daily when building ASP.NET websites.

  • SSDT - What's in a name?

    - by jamiet
    SQL Server Data Tools (SSDT) recently got released as part of SQL Server 2012 and depending on who you believe it can be described as either: a suite of tools for building SQL Server database solutions or a suite of tools for building SQL Server database, Integration Services, Analysis Services & Reporting Services solutions Certainly the SQL Server 2012 installer seems to think it is the latter because it describes SQL Server Data Tools as "the SQL server development environment, including the tool formerly named Business Intelligence Development Studio. Also installs the business intelligence tools and references to the web installers for database development tools" as you can see here: Strange then that, seemingly, there is no consensus within Microsoft about what SSDT actually is. On yesterday's blog post First Release of SSDT Power Tools reader Simon Lampen asked the quite legitimate question:I understand (rightly or wrongly) that SSDT is the replacement for BIDS for SQL 2012 and have just installed this. If this is the case can you please point me to how I can edit rdl and rdlc files from within Visual Studio 2010 and import MS Access reports.To which came the following reply:SSDT doesn't include any BIDs (sic) components. Following up with the appropriate team (Analysis Services, Reporting Services, Integration Services) via their forum or msdn page would be the best way to answer you questions about these kinds of services. That's from a Microsoft employee by the way. Simon is even more confused by this and replies with:I have done some more digging and am more confused than ever. This documentation (and many others) : msdn.microsoft.com/.../ms156280.aspx expressly states that SSDT is where report editing tools are to be foundAnd on it goes....You can see where Simon's confusion stems from. He has official documentation stating that SSDT includes all the stuff for building SSIS/SSAS/SSRS solutions (this is confirmed in the installer, remember) yet someone from Microsoft tells him "SSDT doesn't include any BIDs components".I have been close to this for a long time (all the way through the CTPs) so I can kind of understand where the confusion stems from. To my understanding SSDT was originally the name of the database dev stuff but eventually that got expanded to include all of the dev tools - I guess not everyone in Microsoft got the memo.Does this sound familiar? Have we not been down this road before? The database dev tools have had upteen names over the years (do any of datadude, TSData, VSTS for DB Pros, DBPro, VS2010 Database Projects sound familiar) and I was hoping that the SSDT moniker would put all confusion to bed - evidently its as complicated now as it has ever been.Forgive me for whinging but putting meaningful, descriptive, accurate, well-defined and easily-communicated names onto a product doesn't seem like a difficult thing to do. I guess I'm mistaken!Onwards and upwards...@Jamiet

  • Finding Tools Guidance in OUM

    - by user716869
    OUM is not tool – specific. However, it does include tool guidance.  Tool guidance in OUM includes: a mention of a tool that could be used to complete a specific task(s) templates created with a specific tool example work products in a specific tool links to tool resources Tool Supplemental Guides So how do you find all this helpful tool information? Start at the lowest level first – the Task Overview.  Even though the task overviews are written tool-agnostic, they sometimes mention suggestions, or examples of a tool that might be used to complete the task.  More specific tool information can be found in the Task Overview, Templates and Tools section.  In some cases, the tool used to create the template (for example, Microsoft Word, Powerpoint, Project and Visio) is useful. The Templates and Tools section also provides more specific tool guidance, such as links to: White Papers Viewlets Example Work Products Additional Resources Tool Supplemental Guides If you’re more interested in seeing what tools might be helpful in general for your project or to see if there is any tool guidance for a specific tool that your project is committed to using, go to the Supplemental Guidance page in OUM.  This page is available from the Method Navigation pull down located in the header of almost every OUM page. When you open the Supplemental Guidance page, the first thing you see is a table index of everything that is included on the page.  At the top of the right column are all the Tool Supplemental Guides available in OUM.  Use the index to navigate to any of the guides. Next in the right column is Discipline/Industry/View Resources and Samples.  Use the index to navigate to any of these topics and see what’s available and more specifically, if there is any tool guidance available.  For example, if you navigate to the Cloud Resources, you will find a link to the IT Strategies from Oracle page that provides information for Cloud Practitioner Guides, Cloud Reference Architectures and Cloud White Papers, including the Cloud Candidate Selection Tool and Cloud Computing Maturity Model. The section for Method Tool and Technique Cross References can take you to the Task to Tool Cross Reference.  This page provides a task listing with possible helpful tools and links to more information regarding the tools.  By no means is this tool guidance all inclusive.  You can use other tools not mentioned in OUM to complete an OUM task. The Method Tool and Technique Cross References can also take you to the various Technique pages (Index and Cross References).  While techniques are not necessarily “tools,” they can certainly provide valuable assistance in completing tasks. In the Other Resources section of the Supplemental Guidance page, you find links to the viewlets and white papers that are included within OUM.

  • How to make this .htaccess rule case insensitive?

    - by alex
    This is a rule in my .htaccess # those CSV files are under the DOCROOT ... so let's hide 'em <FilesMatch "\.CSV$"> Order Allow,Deny Deny from all </FilesMatch> I've noticed however that if there is a file with a lowercase or mixed case extension of CSV, it will be ignored by the rule and displayed. How do I make this case insensitive? I hope it doesn't come down to "\.(?:CSV|csv)$" (which I'm not sure would even work, and doesn't cover all bases) Note: The files are under the docroot, and are uploaded automatically there by a 3rd party service, so I'd prefer to implement a rule my end instead of bothering them. Had I set this site up though, I'd go for above the docroot. Thanks

  • Summing the results of Case queries in SQL

    - by David Stelfox
    I think this is a relatively straightforward question but I have spent the afternoon looking for an answer and cannot yet find it. So... I have a view with a country column and a number column. I want to make any number less than 10 'other' and then sum the 'other's into one value. For example, AR 10 AT 7 AU 11 BB 2 BE 23 BY 1 CL 2 I used CASE as follows: select country = case when number < 10 then 'Other' else country end, number from ... This replaces the countries values with less than 10 in the number column to other but I can't work out how to sum them. I want to end up with a table/view which looks like this: AR 10 AU 11 BE 23 Other 12 Any help is greatly appreciated. Cheers, David
