• How to fix a Broadcom 43224 (rev. 01) in ubuntu 12.10, running on a macbook pro 6,2?

  - by Eduardo Bezerra

  I've googled for 3 days so far, with no success, so I'll be straightforward: How do you get it to work? this is the output for lspci -v: 03:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01) Subsystem: Apple Inc. Device 0093 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at c1b00000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: bcma-pci-bridge Kernel modules: bcma for uname -a: Linux fury 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I've tried with bcmwl-kernel-source, firmware-b43-installer and now I'm out of ideas. Can someone help me? This is driving me insane! EDIT: for lspci -nn | grep 0280: 03:00.0 Network controller [0280]: Broadcom Corporation BCM43224 802.11a/b/g/n [14e4:4353] (rev 01) I can see the networks available, but when I try to connect, it gets stuck in a loop: tries to connect, fails, tries again, fails again and so on... EDIT 2: After a long break from this problem, I've just run a few tests again and found out that, although my macbuntu still fails to connect to my home wi-fi network, it works just fine at my university... Does that help in anyway? My home network is managed by a dual-band (2.4Ghz and 5Ghz) 802.11n cisco e4200 wi-fi router.

• Versioning and Continuous Integration with project settings files

  - by Michael Stephenson

  I came across something which was a bit of a pain in the bottom the other week. Our scenario was that we had implemented a helper style assembly which had some custom configuration implemented through the project settings. I'm sure most of you are familiar with this where you end up with a settings file which is viewable through the C# project file and you can configure some basic settings. The settings are embedded in the assembly during compilation to be part of a DefaultValue attribute. You have the ability to override the settings by adding information to your app.config and if the app.config doesn’t override the settings then the embedded default is used. All normal C# stuff so far… Where our pain started was when we implement Continuous Integration and we wanted to version all of this from our build. What I was finding was that the assembly was versioned fine but the embedded default value was maintaining the non CI build version number. I ended up getting this to work by using a build task to change the version numbers in the following files: App.config Settings.settings Settings.designer.cs I think I probably could have got away with just the settings.designer.cs, but wanted to keep them all consistent incase we had to look at the code on the build server for some reason. I think the reason this was painful was because the settings.designer.cs is only updated through Visual Studio and it writes out the code to this file including the DefaultValue attribute when the project is saved rather than as part of the compilation process. The compile just compiles the already existing C# file. As I said we got it working, and it was a bit of a pain. If anyone has a better solution for this I'd love to hear it

• What web technology could I use which would support a decision tree?

  - by Rami Alhamad

  I am a big game development fan but I haven't done any commercial work in the past. I have been asked by a non-profit to look at developing a game similar to the award-winning www.playspent.org They want the following features: support 5 scenarios mobile isn't important but compatibility with older browsers would be a big bonus they want it to be visual and audible bonus is to have it easily modifiable support 4 languages I don't have much knowledge of Flash and would rather avoid using it as a solution. I started breaking down the problem into segments that I will need to examine, they are as follows: ability to read the game flow from a file that they can produce (xml, etc.) db design to store decision tree language challenge browser compatibility I am leaning towards an Google app engine/GWT solution but I am not sure what technology is best for this. I am really hoping to get your opinion/recommendation on my approach and on what technology is best. A special thanks (and beer if you live in Toronto) will be awarded to anyone who can help give me a ballpark estimate on how much such a game should go for. I know it's tough to estimate but any rough figure will help (how much would you charge for building something like playspent.org?) Thanks in advance

• Marshalling the value of a char* ANSI string DLL API parameter into a C# string

  - by Brian Biales

  For those who do not mix .NET C# code with legacy DLL's that use char* pointers on a regular basis, the process to convert the strings one way or the other is non-obvious. This is not a comprehensive article on the topic at all, but rather an example of something that took me some time to go find, maybe it will save someone else the time. I am utilizing a third party too that uses a call back function to inform my application of its progress.  This callback includes a pointer that under some circumstances is a pointer to an ANSI character string.  I just need to marshal it into a C# string variable.  Seems pretty simple, yes?  Well, it is, (as are most things, once you know how to do them). The parameter of my callback function is of type IntPtr, which implies it is an integer representation of a pointer.  If I know the pointer is pointing to a simple ANSI string, here is a simple static method to copy it to a C# string: private static string GetStringFromCharStar(IntPtr ptr) {     return System.Runtime.InteropServices.Marshal.PtrToStringAnsi(ptr); } The System.Runtime.InteropServices is where to look any time you are mixing legacy unmanaged code with your .NET application.

• What's a good Game development platform for a platformer game with these characteristics?

  - by Joe

  Yes, I know, the best way to make an indie game is to learn to code. I've got some scripting experience, but I want to do worldbuilding with already-existing tools (and communities surrounding those tools), and I've been really impressed with games like An Untitled Story that were made with pre-packaged toolsets at their core, like Game Maker. :) So I'm planning to make my game using either Game Maker or something like it. The basic parameters of my planned game: -2D platformer. -Physics/speed akin to Sonic the Hedgehog. -Large, non-linear world, flowing as seamlessly as possible -- think Super Metroid, but without the forced screen transitions. The first two points have me leaning toward Game Maker -- Plenty of 2D platformers have been made with it, and there are serviceable, openly available Sonic-the-Hedgehog-style physics engines for it that could be adapted to my needs with minimal muss and fuss. But the third makes me antsy -- from what limited information I hear, Game Maker has problems with large levels/boards/screens/whateveryoucallthem, thus necessitating transitions between screens. I want to avoid that if at all possible -- it would, I believe, fundamentally alter the flow of the game. I understand that generally speaking, the more you have loaded into memory the more things are going to chug (especially for a one-size-fits-all game development platform that isn't a model of efficient coding), but I'm hoping there are systems that can un-load objects that are sufficiently far offscreen and thus better produce seamlessness. Any thoughts, people? :) The sooner I can get a basic pre-fab physics engine and world-building program up and running, the sooner I can start prototyping areas and generally tooling around. Should I be looking at Game Maker, or elsewhere? (My current plan is to more-or-less build the game prototype-style, then worry about art and sound at the very end once the damn thing is playable.)

• How can I upgrade my server's kernel without rebooting?

  - by Oli

  This is a loaded question because I'm already aware of, and am very interested in ksplice. The problem is that since they were bought by Oracle, they have been forced to pull numerous server distributions from the offerings. The answer isn't as simple as it once was. I noticed a question on Unix.SE that states: You can build your own ksplice patches to dynamically load into your own kernel Great! But how?! I've installed the free ksplice package in the repo on my desktop (not ksplice-uptrack which is non-free) and now want to generate and apply updates. What's the process? Are there any scripts out there to automate the process? Moreover, if all the machinery required for rebootless upgrades is sitting there in the kernel (and ksplice package), why on earth aren't we taking advantage of it by default? Note 1: I am happy for a solution beside ksplice but it has to deliver the same thing: rolling updates to the kernel that can be applied without rebooting the server. Note 2: I'll say it again; the main ksplice "service" does not support Ubuntu Server. It used to but it doesn't any more. When I talk about wanting to use ksplice, I'm talking about the open source tools in the ksplice package. Any answer that talks about ksplice-uptrack is probably not what I'm after as this is the part that integrates directly with aforementioned "service".

• Simplify Your Code with LINQ

  - by dwahlin

  I’m a big fan of LINQ and use it wherever I can to minimize code and make applications easier to maintain overall. I was going through a code file today refactoring it based on suggestions provided by Resharper and came across the following method: private List<string> FilterTokens(List<string> tokens) { var cleanedTokens = new List<string>(); for (int i = 0; i < tokens.Count; i++) { string token = tokens[i]; if (token != null) { cleanedTokens.Add(token); } } return cleanedTokens; }   In looking through the code I didn’t see anything wrong but Resharper was suggesting that I convert it to a LINQ expression: In thinking about it more the suggestion made complete sense because I simply wanted to add all non-null token values into a List<string> anyway. After following through with the Resharper suggestion the code changed to the following. Much, much cleaner and yet another example of why LINQ (and Resharper) rules: private List<string> FilterTokens(IEnumerable<string> tokens) { return tokens.Where(token => token != null).ToList(); }

• SQL Saturday Atlanta: Intro To Performance Tuning

  - by Mike Femenella

  I'm looking forward to speaking in Atlanta on the 24th, will be fun to get back down that way to visit with some friends and present two topics that I really enjoy. First, an introduction to performance tuning. Performance tuning is a very wide and deep topic and we're staying close to the surface. I direct this class for newbie sql users who have less than 2 years of experience. It's all the things I wish someone would have told me in my first 2 years about what to look for when the database was slow...or allegedly slow I should say. We'll cover using profiler to find slow performing queries and how to save the data off to a table as well as a tour of other features. The difference between clustered, non clustered and covering indexes. How to look at and understand an execution plan (at a high level) and finally the difference between a temp table and a table variable and what the implications are of using either one in your code. That pretty much takes up a full hour. Second presentation, Loading Data in Real Time. It's really a presentation about partitioning but with a twist that we used at work recently to solve a need to load some data quickly and put it into production with minimal downtime. We'll cover partition functions, schemes,$partition, merge, sys.partitions and show some examples of building a set of partitioned tables and using the switch statement to move it from one table to another. Finally we'll cover the differences in partitioning between 2005 and 2008. Hope to see you there! And if you read my blog please introduce yourself!

• SharePoint 2010 PowerShell Script to Find All SPShellAdmins with Database Name

  - by Brian Jackett

  Problem     Yesterday on Twitter my friend @cacallahan asked for some help on how she could get all SharePoint 2010 SPShellAdmin users and the associated database name.  I spent a few minutes and wrote up a script that gets this information and decided I’d post it here for others to enjoy.     Background     The Get-SPShellAdmin commandlet returns a listing of SPShellAdmins for the given database Id you pass in, or the farm configuration database by default.  For those unfamiliar, SPShellAdmin access is necessary for non-admin users to run PowerShell commands against a SharePoint 2010 farm (content and configuration databases specifically).  Click here to read an excellent guest post article my friend John Ferringer (twitter) wrote on the Hey Scripting Guy! blog regarding granting SPShellAdmin access.  Solution     Below is the script I wrote (formatted for space and to include comments) to provide the information needed. Click here to download the script.   # declare a hashtable to store results $results = @{}   # fetch databases (only configuration and content DBs are needed) $databasesToQuery = Get-SPDatabase | Where {$_.Type -eq 'Configuration Database' -or $_.Type -eq 'Content Database'}   # for each database get spshelladmins and add db name and username to result $databasesToQuery | ForEach-Object {$dbName = $_.Name; Get-SPShellAdmin -database $_.id | ForEach-Object {$results.Add($dbName, $_.username)}}   # sort results by db name and pipe to table with auto sizing of col width $results.GetEnumerator() | Sort-Object -Property Name | ft -AutoSize     Conclusion     In this post I provided a script that outputs all of the SPShellAdmin users and the associated database names in a SharePoint 2010 farm.  Funny enough it actually took me longer to boot up my dev VM and PowerShell (~3 mins) than it did to write the first working draft of the script (~2 mins).  Feel free to use this script and modify as needed, just be sure to give credit back to the original author.  Let me know if you have any questions or comments.  Enjoy!         -Frog Out   Links PowerShell Hashtables http://technet.microsoft.com/en-us/library/ee692803.aspx SPShellAdmin Access Explained http://blogs.technet.com/b/heyscriptingguy/archive/2010/07/06/hey-scripting-guy-tell-me-about-permissions-for-using-windows-powershell-2-0-cmdlets-with-sharepoint-2010.aspx

• Which web framework or technologies would suit me?

  - by Suraj Chandran

  Hi, I had been working on desktop apps and server side(non web) for some time and now I am diving in to web first time. I plan to write a scalable enterprise level app. I have worked with Java, Javascript, Jquery etc. but I absolutely hate jsp. So is there any framework that focuses on developing enterprise level web apps without jsp. I liked Wicket's approach, but I think there is a little lack of support of dynamic html in it and jquery(yes i looked at wiquery). Also I feel making wicket apps scalable would take some sweat. Can Spring MVC, Struts2 etc. help me make with this with just using say Java, JavaScript, and JQuery. Or are there any other options for me like Wicket. Please do forgive if anything above looks insane, I am still working on my understanding with enterprise web apps. NOTE: If you think that I should take a different direction or approach, please do suggest!

• Upgrade won't allow second display to go to 1920x1080

  - by Rick

  I just upgraded to 10.10 last night and I'm having issues now with dual display from my laptop dock. This was working in the previous release with a manual xrandr command: xrandr --output LVDS1 --off --output DP1 --mode 1920x1080 && xrandr --output VGA1 --mode 1920x1080 --left-of DP1 When I run this now, the DP1 output doesn't have a mode for 1920x1080. The two displays are a matched pair of dell 22" that are both 1920x1080. When I attempt to manually add the mode xrandr --addmode DP1 1920x1080 and rerun my command, I lose both displays altogether. I have to then blindly reset to just one of them in order to get display back. If I avoid the 1920 and just attempt to setup DP1 at the 1280x1024 max it thinks it has, then the second display will come up, but obviously looks horrible since it's non-native resolution. I've grabbed the updated xorg intel driver from the stable X ppa and am running: 2:2.13.901-2ubuntu2~xup~maverick xrandr output Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 LVDS1 connected (normal left inverted right x axis y axis) 1280x800 60.2 + 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 HDMI1 disconnected (normal left inverted right x axis y axis) DP1 connected (normal left inverted right x axis y axis) 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1

• What's the best way to generate an NPC's face using web technologies?

  - by Vael Victus

  I'm in the process of creating a web app. I have many randomly-generated non-player characters in a database. I can pull a lot of information about them - their height, weight, down to eye color, hair color, and hair style. For this, I am solely interested in generating a graphical representation of the face. Currently the information is displayed with text in the nicest way possible, but I believe it's worth generating these faces for a more... human experience. Problem is, I'm not artist. I wouldn't mind commissioning an artist for this system, but I wouldn't know where to start. Were it 2007, I'd naturally think to myself that using Flash would be the best choice. I'd love to see "breathing" simulated. However, since Flash is on its way out, I'm not sure of a solid solution. With a previous game, I simply used layered .pngs to represent various aspects of the player's body: their armor, the face, the skin color. However, these solutions weren't very dynamic and felt very amateur. I can't go deep into this project feeling like that's an inferior way to present these faces, and I'm certain there's a better way. Can anyone give some suggestion on how to pull this off well?

At first I came up with implementing the functions directly into the vector class... public class Vector3D { public static Vector3D LinearInterpolate(Vector3D vector1, Vector3D vector2, double factor) { ... } public Vector3D LinearInterpolate(Vector3D other, double factor { ... } } (I always offer both: a static method with two vectors as parameters and one non-static, with only one vector as parameter) ...but then I got the idea to use extension methods (defined in a seperate class called "Interpolation" for example), since interpolation isn't really a thing only available for vectors. So this could be another solution: public class Vector3D { ... } public static class Interpolation { public static Vector3D LinearInterpolate(this Vector3D vector, Vector3D other, double factor) { ... } } So here an example how you'd use the different possibilities: { var vec1 = new Vector3D(5, 3, 1); var vec2 = new Vector3D(4, 2, 0); Vector3D vec3; vec3 = vec1.LinearInterpolate(vec2, 0.5); //1 vec3 = Vector3D.LinearInterpolate(vec1, vec2, 0.5); //2 //or with extension-methods vec3 = vec1.LinearInterpolate(vec2, 0.5); //3 (same as 1) vec3 = Interpolation.LinearInterpolation(vec1, vec2, 0.5); //4 } So I really don't know which design is better. Also I don't know if there's an ultimate rule for things like this or if it's just about what someone personally prefers. But I really would like to hear your opinions, what's better (and if possible why ).

• bluetooth daemon not running at startup

  - by ffaxer

  I'm trying to connect a bluetooth mouse to my Xubuntu system using Blueman (v. 1.21) Problem seems to be bluetoothd not running at startup, so blueman refuses to start, only a dialog appears: "Bluez daemon is not running, blueman-manager cannot continue." On my system, bluetoothd will run only as root (sudo), so my current workaround is simply to sudo bluetoothd manually, which works fine but id like to have it run at startup so that my mouse is just working without any interaction from me, if possible. If i try to start bluetoothd as non-root it reports: Bluetooth deamon 4.91 Unable to get on D-Bus In the startup scripts i found the same bluetoothd script in all runlevels and init.d: DAEMON=/usr/sbin/bluetoothd test -f /usr/sbin/bluetoothd || exit 0 # bluetoothd normally starts up by udev rules. it needs dbus to function, log_progress_msg "bluetoothd" pkill -TERM bluetoothd || true log_progress_msg "bluetoothd" I looked in /etc/udev/rules.d/ but no reference to bluetoothd. Further i have already tried with no luck: Editing /etc/dbus-1/system.d/bluetooth.conf to include my user (essentially copying the part that was for root): I tried it while both keeping the root policy and without, still, no luck! Editing /etc/pam.d/common-session and /etc/pam.d/gdm to include the line: session optional pam_ck_connector.so In the case of common-session it was already there but with a "nox11" which i tried removing. No luck no luck. Btw, I'm confused as to which session manager I'm using, since i have both xfce4-session and gdm-session-worker running. Anyways, hope someone is savvy enough to figure it out or bring some hints, otherwise i sincerely apologize for wasting your time! I'll sign off with uname -a: Linux [mycompname] 3.0.0-9-lowlatency #12ppa1~natty1-Ubuntu SMP PREEMPT Mon Aug 22 06:52:15 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Peace B)

• Is 'Protection' an acceptable Java class name

  - by jonny

  This comes from a closed thread at stack overflow, where there are already some useful answers, though a commenter suggested I post here. I hope this is ok! I'm trying my best to write good readable, code, but often have doubts in my work! I'm creating some code to check the status of some protected software, and have created a class which has methods to check whether the software in use is licensed (there is a separate Licensing class). I've named the class 'Protection', which is currently accessed, via the creation of an appProtect object. The methods in the class allow to check a number of things about the application, in order to confirm that it is in fact licensed for use. Is 'Protection' an acceptable name for such a class? I read somewhere that if you have to think to long in names of methods, classes, objects etc, then perhaps you may not be coding in an Object Oriented way. I've spent a lot of time thinking about this before making this post, which has lead me to doubt the suitability of the name! In creating (and proof reading) this post, I'm starting to seriously doubt my work so far. I'm also thinking I should probably rename the object to applicationProtection rather than appProtect (though am open to any comments on this too?). I'm posting non the less, in the hope that I'll learn something from others views/opinions, even if they're simply confirming I've "done it wrong"!

• Can anyone explain step-by-step how the as3isolib depth-sorts isometric objects?

  - by Rob Evans

  The library manages to depth-sort correctly, even when using items of non-1x1 sizes. I took a look through the code but it's a big project to go through line by line! There are some questions about the process such as: How are the x, y, z values of each object defined? Are they the center points of the objects or something else? I noticed that the IBounds defines the bounds of the object. If you were to visualise a cuboid of 40, 40, 90 in size, where would each of the IBounds metrics be? I would like to know how as3isolib achieves this although I would also be happy with a generalised pseudo-code version. At present I have a system that works 90% of the time but in cases of objects that are along the same horizontal line, the depth is calculated as the same value. The depth calculation currently works like this: x = object horizontal center point y = object vertical center point originX and Y = the origin point relative to the object so if you want the origin to be the center, the value would be originX = 0.5, originY = 0.5. If you wanted the origin to be vertical center, horizontal far right of the object it would be originX = 1.0, originY = 0.5. The origin adjusts the position that the object is transformed from. AABB_width = The bounding box width. AABB_height = The bounding box height. depth = x + (AABB_width * originX) + y + (AABB_height * originY) - z; This generates the same depth for all objects along the same horizontal x.

• Real world pitfalls of introducing F# into a large codebase and engineering team

  - by nganju

  I'm CTO of a software firm with a large existing codebase (all C#) and a sizable engineering team. I can see how certain parts of the code would be far easier to write in F#, resulting in faster development time, fewer bugs, easier parallel implementations, etc., basically overall productivity gains for my team. However, I can also see several productivity pitfalls of introducing F#, namely: 1) Everyone has to learn F#, and it's not as trivial as switching from, say, Java to C#. Team members that have not learned F# will be unable to work on F# parts of the codebase. 2) The pool of hireable F# programmers, as of now (Dec 2010) is non-existent. Search various software engineer resume databases for "F#", way less than 1% of resumes contain the keyword. 3) Community support as of now (Dec 2010) is less available. You can google almost any problem in C# and find someone that has already dealt with it, not so with F#. Third party tool support (NUnit, Resharper etc) is also sketchy. I realize that this is a bit Catch-22, i.e. if people like me don't use F# then the community and tools will never materialize, etc. But, I've got a company to run, and I can be cutting edge but not bleeding edge. Any other pitfalls I'm not considering? Or anyone care to rebut the pitfalls I've mentioned? I think this is an important discussion and would love to hear your counter-arguments in this public forum that may do a lot to increase F# adoption by industry. Thanks.

• Dlink DWA-643 ExpressCard / Atheros AR5008 can't connect to wifi networks

  - by Justin Kelly

  I've just purchased a D-Link DWA-643 Xtreme N ExpressCard Notebook Adapter - but it can't connect to my wireless network The card is listed on the FSF website and - refer links below: http://www.fsf.org/resources/hw/index_html/net/wireless/index_html/cards.html http://www.dlink.com.au/products/?pid=550 Ubuntu see the card as using the Atheros AR5008 chipset - refer image below The card lights up and I can see that available wifi networks using this card - so it seems to 'just work' on ubuntu 12.04 but when i try and connect to my networks - it fails I've tried setting the network to all the different options (WEP, WPA2, no encryption, etc.. b/g/n ) but ubuntu sill cant connect to it I've also installed wicd but still couldn't connect Has anyone got a DWA-643 to work in Ubuntu? Or does anyone have any suggestion on how to get it to connect?? Any help would be greatly appreciated Note: the laptop has built in wifi but its broadcom, works but with dialup speed connection - and i've had nothign but trouble using the boardcom drivers so purchased the FSF recommended PCI expresscard as i hoped it would 'just work' on the latest Ubuntu i've have tried to disable the built in wifi - broadcom - but even with the broadcom uninstall and unavailable it didnt help the dlink to connect previously I had MAC address filtering on the router - i've added the dlinks MAC - and also disabled MAC address filtering - still no luck lspci output below: 18:00.0 Network controller: Atheros Communications Inc.

• SQLRally Nordic gets underway

  - by Rob Farley

  PASS is becoming more international, which is great. The SQL Community has always been international – it’s not as if data is only generated in North America. And while it’s easy for organisations to have a North American focus, PASS is taking steps to become international. Regular readers will be aware that I’m one of three advisors to the PASS Board of Directors, with a focus on developing PASS as a more global organisation. With this in mind, it’s great that today is Day 1 of SQLRally Nordic, being hosted in in Sweden – not only a non-American country, but one that doesn’t have English as its major language. The event has been hosted by the amazing Johan Åhlén and Raoul Illyés, two guys who I met earlier this year, but the thing that amazes me is the incredible support that this event has from the SQL Community. It’s been sold out for a long time, and when you see the list of speakers, it’s not surprising. Some of the industry’s biggest names from Microsoft have turned up, including Mark Souza (who is also a PASS Director), Thomas Kejser and Tobias Thernström. Business Intelligence experts such as Jen Stirrup, Chris Webb, Peter Myers, Marco Russo and Alberto Ferrari are there, as are some of the most awarded SQL MVPs such as Itzik Ben-Gan, Aaron Bertrand and Kevin Kline. The sponsor list is also brilliant, with names such as HP, FusionIO, SQL Sentry, Quest and SolidQ complimented by Swedish companies like Cornerstone, Informator, B3IT and Addskills. As someone who is interested in PASS becoming global, I’m really excited to see this event happening, and I hope it’s a launch-pad into many other international events hosted by the SQL community. If you have the opportunity, thank Johan and Raoul for putting this event on, and the speakers and sponsors for helping support it. The noise from Twitter is that everything is going fantastically well, and everyone involved should be thoroughly congratulated! @rob_farley

• still about perl vs python but (to me) slightly different from what has been asked [closed]

  - by B Chen

  Being a newbie to coding, I read from this site that Perl is still as viable as it has been, while Python, quoted from someone else's post, is good but just "snake oil" (not sure what this refers to exactly though). So from the responses in that post, I got the gist that Perl is good and worthy to learn. My question is - pardon me for phrasing it in this "non-programmer's" way - Which one should I learn FIRST? (I am actually currently learning R) Here below is the background info - (a) I will be using it mostly for data mining and statistics analysis (b) Will there be this "first" and "later" issue with learning either Perl or Python? That is, after I become competent with one language, would there be a need to learn the second one (for a similar task??) (c) If there should be circumstances where I must learn the second one, would learning Perl FIRST be better than learning Python? I hope to learn as much from exchanging info here, so please help provide with more than just "it depends" type of info. Great many thanks to all who choose to respond to my query.

• DotNetNuke + PayPal

  - by Nuri Halperin

  A DotNetNuke i'm supporting has had a paypal "buy now" button and other variations with custom fields for a while now. About 2 weeks ago (somewhere in March 2010) they all stopped working. The problem manifested such that once you clicked the "buy now" button, Paypal site would throw a scary error page to the effect of: "Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log" Once I verified no cheeky content editor changed the page, I went digging for answers. The main source incompatibility of PayPal's simple HTML forms is that DNN includes a form on every page, and nested forms are not really supported. As blogged here and lamented here, the solution I came up with is simply to modify the form enctype to 'application/x-www-form-urlencoded' as illustrated below: 1: <input type="image" border="0" 2: src="https://www.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" 3: name="submit" 4: alt="PayPal - The safer, easier way to pay online!" 5: onClick="this.form.action='https://www.paypal.com/cgi-bin/webscr'; this.form.enctype='application/x-www-form-urlencoded';this.form.submit();" /> One would think that PayPal would want the masses submitting HTML in all manners of "enctype", but I guess every company has it's quirks. At least my favorite non-profit can now continue and accept payments. Sigh.

• MDX needs a function or macro syntax

  - by Darren Gosbell

  I was having an interesting discussion with a few people about the impact of named sets on performance (the same discussion noted by Chris Webb here: http://cwebbbi.wordpress.com/2011/03/16/referencing-named-sets-in-calculations). And apparently the core of the performance issue comes down to the way named sets are materialized within the SSAS engine. Which lead me to the thought that what we really need is a syntax for declaring a non-materialized set or to take this even further a way of declaring an MDX expression as function or macro so that it can be re-used in multiple places. Because sometimes you do want the set materialised, such as when you use an ordered set for calculating rankings. But a lot of the time we just want to make our MDX modular and want to avoid having to repeat the same code over and over. I did some searches on connect and could not find any similar suggestions so I posted one here: https://connect.microsoft.com/SQLServer/feedback/details/651646/mdx-macro-or-function-syntax Although apparently I did not search quite hard enough as Chris Webb made a similar suggestion some time ago, although he also included a request for true MDX stored procedures (not the .Net style stored procs that we have at the moment): https://connect.microsoft.com/SQLServer/feedback/details/473694/create-parameterised-queries-and-functions-on-the-server Chris also pointed out this post that he did last year http://cwebbbi.wordpress.com/2010/09/13/iccube/ where he pointed out that the icCube product already has this sort of functionality. So if you think either or both of these suggestions is a good idea then I would encourage you to click on the links and vote for them.

• Interfaces and Virtuals Everywhere????

  - by David V. Corbin

  First a disclaimer; this post is about micro-optimization of C# programs and does not apply to most common scenarios - but when it does, it is important to know. Many developers are in the habit of declaring member virtual to allow for future expansion or using interface based designs1. Few of these developers think about what the runtime performance impact of this decision is. A simple test will show that this decision can have a serious impact. For our purposes, we used a simple loop to time the execution of 1 billion calls to both non-virtual and virtual implementations of a method that took no parameters and had a void return type: Direct Call:     1.5uS Virtual Call:   13.0uS The overhead of the call increased by nearly an order of magnitude! Once again, it is important to realize that if the method does anything of significance then this ratio drops quite quickly. If the method does just 1mS of work, then the differential only accounts for a 1% decrease in performance. Additionally the method in question must be called thousands of times in order to produce a meaqsurable impact at the application level. Yet let us consider a situation such as the per-pixel processing of a graphics processing application. Here we may have a method which is called millions of times and even the slightest increase in overhead can have significant ramification. In this case using either explicit virtuals or interface based constructs is likely to be a mistake. In conclusion, good design principles should always be the driving force behind descisions such as these; but remember that these decisions do not come for free.   1) When a concrete class member implements an interface it does not need to be explicitly marked as virtual (unless, of course, it is to be overriden in a derived concerete class). Nevertheless, when accessed via the interface it behaves exactly as if it had been marked as virtual.
