  • design of 'game engine' for small javascript games?

    - by Matt Ball
    I'm making a group of two or three simple javascript games for fun. After someone finishes one game, they'll be presented with a harder or easier version of another game depending on whether the original game was won or lost. I have a high-level question about the design of things: So far I've created a class for one game type that manages the interaction with the UI and the state of the game itself. But for tracking how many of the subgames have been won, or for understanding whether the next game presented should be more or less difficult, are there arguments to be made for making a 'game engine' class? How does the engine communicate to the games? For instance, when a game is won, how is that information relayed to the engine? Is there a better or more common design? (If you want to see what I have so far, the games are slowly taking shape here: https://github.com/yosemitebandit/candela and can be viewed at http://yosemitebandit.com/candela)

  • Speed, delta time and movement

    - by munchor
    player.vx = scroll_speed * dt /* Update positions */ player.x += player.vx player.y += player.vy I have a delta time in miliseconds, and I was wondering how I can use it properly. I tried the above, but that makes the player go fast when the computer is fast, and the player go slow when the computer is slow. The same thing happens with jumping. The player can jump really high when the computer is faster. This is sort of unfair, I think, because. Should I be doing this someway else? Thanks.

  • MythTV GUI problems

    - by oli206
    Hi, I'm using MythTV to watch TV on my ubuntu computer and I'm having a problem with the resolution. It seems that the GUI resolution is matched with the channel resolution, so If I'm watching a HD channel, I get a nice GUI but If I'm watching a SD channel, then it's crap. A couple of screenshots to show the difference: High Definition Channel: Standard Definition Channel: I haven't found any similar issue in the internet and neither an option in the settings menu of MythTV (backend and frontend). I have another small problem that you can see in the first screenshot, the channel name is cut (it shows "Telemadri" and the last letter is not completely shown). Anyone know how can I fix this too? Thanks in advance

  • Oracle Database 11g Underground Advice for Database Administrators, by April C. Sims

    - by alejandro.vargas
    Recently I received a request to review the book "Oracle Database 11g Underground Advice for Database Administrators" by April C. Sims I was happy to have the opportunity know some details about the author, she is an active contributor to the Oracle DBA community, through her blog "Oracle High Availability" . The book is a serious and interesting work, I think it provides a good study and reference guide for DBA's that want to understand and implement highly available environments. She starts walking over the more general aspects and skills required by a DBA and then goes on explaining the steps required to implement Data Guard, using RMAN, upgrading to 11g, etc.

  • Design a T-shirt for .NET Reflector Pro

    - by Laila
    Win a .NET Reflector Pro license, a box of Red Gate goodies, and a t-shirt printed with your design! Red Gate likes t-shirts. Each of our teams has one. In fact, each individual person has one, numbered according to when they joined the company: Red Gate's 1st, 2nd, and so on right up to Red Gate's 170th, with the slogan "More than just a number". Those t-shirts are important, chiefly because they remind the people wearing them that they are important. But that isn't enough. What really makes us great are the people who choose to use our tools. So we'd like to extend our tradition of t-shirts to include you and put the design of our next shirt entirely in your hands. We'd like you to come up with a witty slogan or create an inventive or simply beautiful t-shirt design for .NET Reflector Pro, our add-in for Visual Studio, which allows you to step into decompiled assemblies whilst debugging in Visual Studio. When you're done, post your masterpiece to Twitter with the hash tag #reflectortees, and @redgate will take a look! We'll pick the best design, and the winner will get a licensed copy of .NET Reflector Pro and a box of Red Gate goodies - not to mention a copy of their t-shirt. The winning design will go into production and be worn and given out at tradeshows, conferences, and user group events across the world, proudly bearing the name of their designer. We'll also pick three runners-up who will receive licenses for .NET Reflector Pro. Red Gate goodie box Interested? If you're up for the challenge, then we've got some resources to get you started. Inside the .zip file you'll find high-quality versions of the following: T-shirt templates: don't forget to design the front and the back! Different versions of the .NET Reflector Pro logo and Red Gate logo. Colour sheets to give you an easy reference to the Red Gate colours, including hex and RGB values. You can create and send us as many designs as you like, and each of them will be considered for the prize. To submit your designs, simply tweet including the competition hash tag, #reflectortees, and a link to somewhere we can see your design: either an image hosting site such as Twitpic, Flickr or Picasa, or a personal blog. You will need to create a Twitter account (which is free), if you don't already have one. You only have three limits: The background colour of the t-shirt should be one of our brand colours (red, light/dark grey or black), though you're welcome to use other colours in the rest of the design. You need to make use of either the .NET Reflector Pro logo OR the Red Gate logo (please keep them as they are) If you include any text or slogan, stick with just one or two colors for it. Apart from that, go wild. Go and do whatever it is you do when you get creative: whether you walk barefoot on the grass with a pencil and paper, sit cross-legged on a pile of cushions with a laptop, or simply close your eyes and float through a mist of ideas, now is your chance. Make sure you enjoy it. We're looking forward to seeing your creations. Terms and conditions 1. The closing date for entries is June 11th, 2010 (4 p.m. UK time). Red Gate Software Ltd reserves the right to extend the competition deadline at its discretion. If there is a revision, the revised date will be published on this blog and the date for announcing the results will be postponed accordingly. 2. The winning designer will be notified on June 14th, 2010 through Twitter. The winner must claim his/her prize by sending us a high-resolution image of their design via email (i.e. Illustrator EPS files or appropriate format, ideally at 300dpi). If the winner does not come forward within 3 days of the announcement, they will forfeit their prize and another winner will be selected from the runners-up. The names of the winner and runners-up will be posted on this blog by June 18th.  3. Entry is completed on the designer posting a link to their entry in a tweet with the correct hash tag, #reflectortees. 4. Red Gate Software needs to hold the rights to using the winning design in order to put the t-shirt into production. We will make sure that this is fine with the winner before we do so, but if you do not want us holding the rights to your design, please do not submit your designs. We reserve the right to slightly alter or adjust any artwork we decide to use (mainly to make it easier to print), but we will make sure we contact the winner for approval first. The winner will also need to allow us the use of his/her name for purposes of promoting your design. 5. Entries must be entirely your own original work and must not breach any copyright or third party rights.

  • How do I do TDD on embedded devices?

    - by Darth
    I'm not new to programming and I've even worked with some low level C and ASM on AVR, but I really can't get my head around a larger-scale embedded C project. Being degenerated by the Ruby's philosophy of TDD/BDD, I'm unable to understand how people write and test code like this. I'm not saying it's a bad code, I just don't understand how this can work. I wanted to get more into some low level programming, but I really have no idea how to approach this, since it looks like a completely different mindset that I'm used to. I don't have trouble understanding pointer arithmetics, or how allocating memory works, but when I see how complex C/C++ code looks compared to Ruby, it just seems impossibly hard. Since I already ordered myself an Arduino board, I'd love to get more into some low level C and really understand how to do things properly, but it seems like none of the rules of high level languages apply. Is it even possible to do TDD on embedded devices or when developing drivers or things like custom bootloader, etc.?

  • How Curiosity Took Its Self Portrait [Video]

    - by Jason Fitzpatrick
    There was enough confusion among the public as to how exactly the Curiosity Rover was able to photograph itself without the camera arm intruding into the photo that NASA released this video detailing the process. For those readers familiar with photograph blending and stitching using multiple photo sources, this should come as no surprise. For the unfamiliar, it’s an interesting look at how dozens of photos can be blended together so effectively that the arm–robotic or otherwise–of the photographer can be taken right out. Hit up the link below to read more about how NASA practiced on Earth for the shot and to see a high-res copy of the actual self portrait.

  • Backpacks and Booth Paint: TechEd 2012

    - by The Un-T Guy
    Arriving in the parking lot of the Orange County Convention Center, I immediately knew I was in the right place. As far as the eye could see, the acres of asphalt were awash in backpacks, quirky (to be kind) outfits, and bad haircuts. This was the place. This was Microsoft Mecca v2012 for geeks and nerds, the Central Florida event of the year, a gathering of high tech professionals whose skills I both greatly respect and, frankly, fear a little. I was wholly and completely out of element, a dork in a vast sea of geek jumbo. It like was wearing dockers and a golf shirt walking into a RenFaire, but one with really crappy costumes and no turkey legs...save those attached to some of the attendees. Of course the corporate whores...errrr, vendors were in place, ready to parlay the convention's fre-nerd-ic energy into millions of dollars by convincing the big-brained and under-sexed in the crowd (i.e., virtually all of them...present company excluded, of course) that their product or service was the only thing standing between them and professional success, industry fame, and clear skin. "With KramTech 2012," they seemed to scream, "you will be THE ROCK STAR of your company's IT department!" As car shows and tattoo parlors learned long ago, Tech companies seem to believe that the best way to attract the attention of this crowd is through the hint of the promise of sex. They recruit and deploy an army of "sales reps" whose primary qualifications appear to be long hair, short skirts, high heels, and a vagina. Unlike their distant cousins in the car and body art industries, however, this sub-species of booth paint (semi-gloss decoration that adds nothing to the substance of the product) seems torn between committing to being all-out sex objects and recognition that they are in the presence of intelligent, discerning people. People who are smart enough to know exactly what these vendors are doing. Also unlike their distant car show and tattoo shop cousins, these young women (what…are there no gay tech professionals who could use some eye candy?) seem to realize that while IT remains a male-dominated field, there are ever-increasing numbers of intelligent, capable, strong professional women – women who’ve battled to make it in this field through hard work and work performance rather than a hard body and performing after work. This is not to say that all of the young female sales reps are there only because of their physical attributes. Many are competent, intelligent, and driven -- not to mention attractive. They're working hard on the front lines of delivering the next generation of technology. The distinction is pretty clear, however, between these young professionals and the booth paint. The former enthusiastically deliver credible information about the products they’re hawking. The latter are positioned in the aisles, uncomfortably avoiding eye contact as they struggle to operate the badge readers. Surprisingly, not all of the women in attendance seemed to object to the objectification of their younger sisters. One IT professional woman who came of age in the industry (mostly in IT marketing) said, “I have no problem with it. I was a ‘booth babe’ for years and it doesn’t bother me at all.” Others, however, weren’t quite so gracious. One woman I spoke with, an IT manager from Cheyenne, Wyoming, said it was demeaning and frankly, as more and more women grow into IT management positions, not a great marketing idea. “Using these young women is, to me, no different than vendors giving out t-shirts to attract attention. It’s sad because it’s still hard for a woman to be respected in the IT field and this just perpetuates the outdated notion that IT is a male-dominated field.” She went on to say that decisions by vendors to employ these young women in this “inappropriate way” could impact her purchasing decisions. “I might be swayed toward a vendor who has women on staff who are intelligent and dynamic rather than the vendors who use the ‘decoration’ girls.” So in many ways, the IT industry is no different than most other industries as it struggles to maximize performance by finding and developing talent – all of the talent, not just the 50% with a penis. Women in IT, like their brethren, struggle to find their niche in the field, to grow professionally, and reach for the brass ring, struggling to overcome obstacles as they climb the mountain of professional success in a never-ending cycle of economic uncertainty. But as (generally) well-educated and highly-trained professionals, they are probably better positioned than those in many other industries. Beside, they’ve got one other advantage over their non-IT counterparts as they attempt their ascent to the summit: They’ve already got the backpacks.

  • The Case of the Extra Page: Rendering Reporting Services as PDF

    - by smisner
    I had to troubleshoot a problem with a mysterious extra page appearing in a PDF this week. My first thought was that it was likely to caused by one of the most common problems that people encounter when developing reports that eventually get rendered as PDF is getting blank pages inserted into the PDF document. The cause of the blank pages is usually related to sizing. You can learn more at Understanding Pagination in Reporting Services in Books Online. When designing a report, you have to be really careful with the layout of items in the body. As you move items around, the body will expand to accommodate the space you're using and you might eventually tighten everything back up again, but the body doesn't automatically collapse. One of my favorite things to do in Reporting Services 2005 - which I dubbed the "vacu-pack" method - was to just erase the size property of the Body and let it auto-calculate the new size, squeezing out all the extra space. Alas, that method no longer works beginning with Reporting Services 2008. Even when you make sure the body size is as small as possible (with no unnecessary extra space along the top, bottom, left, or right side of the body), it's important to calculate the body size plus header plus footer plus the margins and ensure that the calculated height and width do not exceed the report's height and width (shown as the page in the illustration above). This won't matter if users always render reports online, but they'll get extra pages in a PDF document if the report's height and width are smaller than the calculate space. Beginning the Investigation In the situation that I was troubleshooting, I checked the properties: Item Property Value Body Height 6.25in   Width 10.5in Page Header Height 1in Page Footer Height 0.25in Report Left Margin 0.1in   Right Margin 0.1in   Top Margin 0.05in   Bottom Margin 0.05in   Page Size - Height 8.5in   Page Size - Width 11in So I calculated the total width using Body Width + Left Margin + Right Margin and came up with a value of 10.7 inches. And then I calculated the total height using Body Height + Page Header Height + Page Footer Height + Top Margin + Bottom Margin and got 7.6 inches. Well, page sizing couldn't be the reason for the extra page in my report because 10.7 inches is smaller than the report's width of 11 inches and 7.6 inches is smaller than the report's height of 8.5 inches. I had to look elsewhere to find the culprit. Conducting the Third Degree My next thought was to focus on the rendering size of the items in the report. I've adapted my problem to use the Adventure Works database. At the top of the report are two charts, and then below each chart is a rectangle that contains a table. In the real-life scenario, there were some graphics present as a background for the tables which fit within the rectangles that were about 3 inches high so the visual space of the rectangles matched the visual space of the charts - also about 3 inches high. But there was also a huge amount of white space at the bottom of the page, and as I mentioned at the beginning of this post, a second page which was blank except for the footer that appeared at the bottom. Placing a textbox beneath the rectangles to see if they would appear on the first page resulted the textbox's appearance on the second page. For some reason, the rectangles wanted a buffer zone beneath them. What's going on? Taking the Suspect into Custody My next step was to see what was really going on with the rectangle. The graphic appeared to be correctly sized, but the behavior in the report indicated the rectangle was growing. So I added a border to the rectangle to see what it was doing. When I added borders, I could see that the size of each rectangle was growing to accommodate the table it contains. The rectangle on the right is slightly larger than the one on the left because the table on the right contains an extra row. The rectangle is trying to preserve the whitespace that appears in the layout, as shown below. Closing the Case Now that I knew what the problem was, what could I do about it? Because of the graphic in the rectangle (not shown), I couldn't eliminate the use of the rectangles and just show the tables. But fortunately, there is a report property that comes to the rescue: ConsumeContainerWhitespace (accessible only in the Properties window). I set the value of this property to True. Problem solved. Now the rectangles remain fixed at the configured size and don't grow vertically to preserve the whitespace. Case closed.

  • 3 Ways to Make Steam Even Faster

    - by Chris Hoffman
    Have you ever noticed how slow Steam’s built-in web browser can be? Do you struggle with slow download speeds? Or is Steam just slow in general? These tips will help you speed it up. Steam isn’t a game itself, so there are no 3D settings to change to achieve maximum performance. But there are some things you can do to speed it up dramatically. Speed Up the Steam Web Browser Steam’s built-in web browser — used in both the Steam store and in Steam’s in-game overlay to provide a web browser you can quickly use within games – can be frustratingly slow on many systems. Rather than the typical speed we’ve come to expect from Chrome, Firefox, or even Internet Explorer, Steam seems to struggle. When you click a link or go to a new page, there’s a noticeable delay before the new page appears — something that doesn’t happen in desktop browsers. Many people seem to have made peace with this slowness, accepting that Steam’s built-in browser is just bad. However, there’s a trick that will eliminate this delay on many systems and make the Steam web browser fast. This problem seems to arise from an incompatibility with the Automatically Detect Proxy Settings option, which is enabled by default on Windows. This is a compatibility option that very few people should actually need, so it’s safe to disable it. To disable this option, open the Internet Options dialog — press the Windows key to access the Start menu or Start screen, type Internet Options, and click the Internet Options shortcut. Select the Connections tab in the Internet Options window and click the LAN settings button. Uncheck the Automatically detect settings option here, then click OK to save your settings. If you experienced a significant delay every time a web page loaded in Steam’s web browser, it should now be gone. In the unlikely event that you encounter some sort of problem with your network connection, you could always re-enable this option. Increase Steam’s Game Download Speed Steam attempts to automatically select the nearest download server to your location. However, it may not always select the ideal download server. Or, in the case of high-traffic events like big seasonal sales and huge game launches, you may benefit from selecting a less-congested server. To do this, open Steam’s settings by clicking the Steam menu in Steam and selecting Settings. Click over to the Downloads tab and select the closest download server from the Download Region box. You should also ensure that Steam’s download bandwidth isn’t limited from here. You may want to restart Steam and see if your download speeds improve after changing this setting. In some cases, the closest server might not be the fastest. One a bit farther away could be faster if your local server is more congested, for example. Steam once provided information about content server load, which allowed you to select a regional server that wasn’t under high-load, but this information no longer seems to be available. Steam still provides a page that shows you the amount of download activity happening in different regions, including statistics about the difference in download speeds in different US states, but this information isn’t as useful. Accelerate Steam and Your Games One way to speed up all your games — and Steam itself —  is by getting a solid-state drive and installing Steam to it. Steam allows you to easily move your Steam folder — at C:\Program Files (x86)\Steam by default — to another hard drive. Just move it like you would any other folder. You can then launch the Steam.exe program as if you had never moved Steam’s files. Steam also allows you to configure multiple game library folders. This means that you can set up a Steam library folder on a solid-state drive and one on your larger magnetic hard drive. Install your most frequently played games to the solid-state drive for maximum speed and your less frequently played ones to the slower magnetic hard drive to save SSD space. To set up additional library folders, open Steam’s Settings window and click the Downloads tab. You’ll find the Steam Library Folders option here. Click the Add Library Folder button and create a new game library on another hard drive. When you install a game in Steam, you’ll be asked which library folder you want to install it to. With the proxy compatibility option disabled, the correct download server chosen, and Steam installed to a fast SSD, it should be a speed demon. There’s not much more you can do to speed up Steam, short of upgrading other hardware like your computer’s CPU. Image Credit: Andrew Nash on Flickr

  • Second display running off laptop VGA not correctly positioned (offset left and up)

    - by Filthy Pazuzu
    I have black bars on the right and bottom of my display! I'm running my laptop's VGA output to an recognized as a It is 20", but the assumed 3" difference does not account for the incorrect position. Everything displays fine. It runs high-res video beautifully. But it's 3/4" offset left and an unreasonably annoying 1/4" offset up. I've tried going through the display's annoying & useless menu, but it doesn't have any way to adjust the position. I'm certainly no linux newbie, but on this Ubuntu (Pangolin, BTW) I can't figure out how to make simple positional display changes on Ubuntu. It's not only frustrating, it's a bit humiliating! So. Does anyone know of an app that will allow me to make basic display position alterations? ("App" - annoyingly trendy, but a useful word - no matter how grating.) Thanks, & Cheers, Paz

  • Big Data – Buzz Words: What is Hadoop – Day 6 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned what is NoSQL. In this article we will take a quick look at one of the four most important buzz words which goes around Big Data – Hadoop. What is Hadoop? Apache Hadoop is an open-source, free and Java based software framework offers a powerful distributed platform to store and manage Big Data. It is licensed under an Apache V2 license. It runs applications on large clusters of commodity hardware and it processes thousands of terabytes of data on thousands of the nodes. Hadoop is inspired from Google’s MapReduce and Google File System (GFS) papers. The major advantage of Hadoop framework is that it provides reliability and high availability. What are the core components of Hadoop? There are two major components of the Hadoop framework and both fo them does two of the important task for it. Hadoop MapReduce is the method to split a larger data problem into smaller chunk and distribute it to many different commodity servers. Each server have their own set of resources and they have processed them locally. Once the commodity server has processed the data they send it back collectively to main server. This is effectively a process where we process large data effectively and efficiently. (We will understand this in tomorrow’s blog post). Hadoop Distributed File System (HDFS) is a virtual file system. There is a big difference between any other file system and Hadoop. When we move a file on HDFS, it is automatically split into many small pieces. These small chunks of the file are replicated and stored on other servers (usually 3) for the fault tolerance or high availability. (We will understand this in the day after tomorrow’s blog post). Besides above two core components Hadoop project also contains following modules as well. Hadoop Common: Common utilities for the other Hadoop modules Hadoop Yarn: A framework for job scheduling and cluster resource management There are a few other projects (like Pig, Hive) related to above Hadoop as well which we will gradually explore in later blog posts. A Multi-node Hadoop Cluster Architecture Now let us quickly see the architecture of the a multi-node Hadoop cluster. A small Hadoop cluster includes a single master node and multiple worker or slave node. As discussed earlier, the entire cluster contains two layers. One of the layer of MapReduce Layer and another is of HDFC Layer. Each of these layer have its own relevant component. The master node consists of a JobTracker, TaskTracker, NameNode and DataNode. A slave or worker node consists of a DataNode and TaskTracker. It is also possible that slave node or worker node is only data or compute node. The matter of the fact that is the key feature of the Hadoop. In this introductory blog post we will stop here while describing the architecture of Hadoop. In a future blog post of this 31 day series we will explore various components of Hadoop Architecture in Detail. Why Use Hadoop? There are many advantages of using Hadoop. Let me quickly list them over here: Robust and Scalable – We can add new nodes as needed as well modify them. Affordable and Cost Effective – We do not need any special hardware for running Hadoop. We can just use commodity server. Adaptive and Flexible – Hadoop is built keeping in mind that it will handle structured and unstructured data. Highly Available and Fault Tolerant – When a node fails, the Hadoop framework automatically fails over to another node. Why Hadoop is named as Hadoop? In year 2005 Hadoop was created by Doug Cutting and Mike Cafarella while working at Yahoo. Doug Cutting named Hadoop after his son’s toy elephant. Tomorrow In tomorrow’s blog post we will discuss Buzz Word – MapReduce.

  • Is gstreamer the best encoder for vorbis or is there a better encoding engine I should use?

    - by sayth
    I have sound juicer installed and I want to rip to vorbis.ogg. Is gstreamer the best encoder for vorbis or is there a better encoding engine I should use. The default gstreamer profile is audio/x-raw-float,rate=44100,channels=2 ! vorbisenc name=enc quality=0.5 ! oggmux I am going to raise the quality to 0.7 but thats all nothing if gstreamer isn't the best encoder. Any suggestions for high quality ripping? Edit: a good answer to this will also be the top search result in google for "best vorbis encoding engine". Double Edit: It appears oggenc itself is the best encoder which rules out using sound juicer to rip cd's as it uses gstreamer. I have installed oggenc and am testing the command ripper abcde. Found a good configuration for it here oggenc config for abcde

  • Composite Moon Map Offers Stunning Views of the Lunar Surface [Astronomy]

    - by Jason Fitzpatrick
    Researchers at Arizona State University have stitched together a massive high-resolution map of the moon; seen the moon in astounding detail. Using images fro the Lunar Reconnaissance Orbiter (LRO) they carefully stitch a massive map of the moon with a higher resolution than the public has ever seen before: The WAC has a pixel scale of about 75 meters, and with an average altitude of 50 km, a WAC image swath is 70 km wide across the ground-track. Because the equatorial distance between orbits is about 30 km, there is nearly complete orbit-to-orbit stereo overlap all the way around the Moon, every month. Using digital photogrammetric techniques, a terrain model was computed from this stereo overlap. Hit up the link below to check out the images and the process they used.

  • Dynamically switching the theme in Orchard

    - by Bertrand Le Roy
    It may sound a little puzzling at first, but in Orchard CMS, more than one theme can be active at any given time. The reason for that is that we have an extensibility point that allows a module (or a theme) to participate in the choice of the theme to use, for each request. The motivation for building the theme engine this way was to enable developers to switch themes based on arbitrary criteria, such as user preferences or the user agent (if you want to serve a mobile theme for phones for example). The choice is made between the active themes, which is why there is a difference between the default theme and the active themes. In order to have a say in the choice of the theme, all you have to do is implement IThemeSelector. That interface is quite simple as it only has one method, GetTheme, that takes the current RequestContext and returns a ThemeSelectorResult or null if the implementation of the interface does not want to participate in the current request (we'll see an example in a moment). ThemeSelectorResult itself is just a ThemeName string property and an integer Priority. We're using a priority so that an arbitrary number of implementations of IThemeSelector can contribute to the choice of a theme. If you look for existing implementations of the interface in Orchard, you'll find four: AdminThemeSelector: selects the TheAdmin theme with a very high priority (100) if the current request is for a page that is part of the admin. Otherwise, null is returned, which enables other implementations to choose the theme. PreviewThemeSelector: selects the preview theme if there is one, with a high priority (90), and null otherwise. This enables administrators to view the site under a different theme while everybody else continues to see the current default theme. SiteThemeSelector: this is the implementation that is doing what you expect most of the time, which is to get the current theme from site settings and set it with a priority of –5. SafeModeThemeSelector: this is the fallback implementation, which should almost never win. It sets the theme as the safe mode theme, which has no style and just uses the default templates for everything. The priority is very low (-100). While this extensibility mechanism is great to have, I wanted to bring that level of choice into the hands of the site administrator rather than just developers. In order to achieve that, I built the Vandelay Theme Picker module. The module provides administration UI to create rules for theme selection. It provides its own extensibility point (the IThemeSelectionRule interface) and one implementation of a rule: UserAgentThemeSelectorRule. This rule gets the current user agent from the context and tries to match it with a regular expression that the administrator can configure in the admin UI. You can for example configure a rule with a regular expression that matches IE6 and serve a different subtheme where the stylesheet has been tweaked for such an antique browser. Another possible configuration is to detect mobile devices from their agent string and serve the mobile theme. All those operations can be done with this module entirely from the admin UI, without writing a line of code. The module also offers the administrator the opportunity to inject a link into the front-end in a specific zone and with a specific position that enables the user to switch to the default theme if he wishes to. This is especially useful for sites that use a mobile theme but still want to allow users to use the full desktop site. While the module is nice and flexible, it may be overkill. On my own personal blog, I have only two active themes: the desktop theme and the mobile theme. I'm fine with going into code to change the criteria on which to switch the theme, so I'm not using my own Theme Picker module. Instead, I made the mobile theme a theme with code (in other words there is a csproj file in the theme). The project includes a single C# file, my MobileThemeSelector for which the code is the following: public class MobileThemeSelector : IThemeSelector { private static readonly Regex _Msie678 = new Regex(@"^Mozilla\/4\.0 \(compatible; MSIE [678]" + @"\.0; Windows NT \d\.\d(.*)\)$", RegexOptions.IgnoreCase); private ThemeSelectorResult _requestCache; private bool _requestCached; public ThemeSelectorResult GetTheme(RequestContext context) { if (_requestCached) return _requestCache; _requestCached = true; var userAgent = context.HttpContext.Request.UserAgent; if (userAgent.IndexOf("phone", StringComparison.OrdinalIgnoreCase) != -1 || _Msie678.IsMatch(userAgent) || userAgent.IndexOf("windows live writer", StringComparison.OrdinalIgnoreCase) != -1) { _requestCache = new ThemeSelectorResult { Priority = 10, ThemeName = "VuLuMobile" }; } return _requestCache; } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The theme selector selects the current theme for Internet Explorer versions 6 to 8, for phones, and for Windows Live Writer (so that the theme that is used when I write posts is as simple as possible). What's interesting here is that it's the theme that selects itself here, based on its own criteria. This should give you a good panorama of what's possible in terms of dynamic theme selection in Orchard. I hope you find some fun uses for it. As usual, I can't wait to see what you're going to come up with…
