• Disable the Old Adobe Flash Plugin in Google Chrome

  - by The Geek

  If you’ve just updated to the Dev or Beta release of Google Chrome, you might have noticed that a special version of Adobe Flash is now integrated into the default distribution of Chrome. But what about your old plug-in? As it turns out, the old plug-in is generally still installed… but you can easily disable Chrome plug-ins in the latest version, so let’s get to work. Disable the Extra Flash Plug-in Head over to about:plugins and look through the list—you should notice two Shockwave Flash plugins. The first one should be in your Google Chrome installation folder, and has the filename gcswf32.dll. This is the NEW one, so don’t disable it! If you keep scrollling down, you’ll see the old one, with the file name NPSWF32.dll. This is the OLD plugin, and you can safely disable it. Of course, if you only use Chrome you could just completely uninstall Adobe Flash from your system by heading into Control Panel’s Uninstall Programs screen, and then finding and uninstalling Adobe Flash Player Plugin. The ActiveX version is for Internet Explorer. We’ve not done any testing to see if the old Flash plugin is even still active or not, but may as well disable it just to be sure, right?

• Geek Bike Ride Sao Paulo

  - by Tori Wieldt

  What do you do on sunny Saturday in Sao Paulo when you have several Java enthusiasts, street lanes closed off for bicyclists, new cool Duke jerseys, and some wonderful bike angels to provide a tour through the city? A GEEK BIKE RIDE, of course! The weekend before JavaOne Latin America, the Sao Paulo geek bike ride was held today. We had 20+ riders and a wonderful route that took us from the Bicycle Park to and through downtown. It was a 30Km ride, but our hosts were kind enough to give riders the option to take the subway for part of the trip. Thanks to our wonderful bike angels, the usual rental bike problems like rubbing brakes, dropped chains, and even a flat tire were handled with ease.  The geek bike ride wasn't just for out-of-towners. Loiane Groner, who lives in Sao Paulo said, "I love the Geek Bike Ride! The last time I was in these parts of the city, I think I was five years-old!" A good time was had by all. (My only crash of the day was riding up an escalator with my bike. Luckily, the bikers with me were so busy helping me that no pictures were taken. <phew>) Enjoy this video by Hugo Lavalle You can also view Hugo's pictures. More pictures to come on Stephen Chin's blog.  So, what city is up next?

• Encrypting a non-linux partition with LUKS.

  - by linuxn00b

  I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD. I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT same size (using GParted's "Round to MiB" option) and ran this command: sudo cryptsetup luksFormat /dev/xxx Where xxx is the partition's device name. Then I typed in my new passphrase and confirmed it. Oddly, the command exited immediately after, so I guess it doesn't encrypt the entire partition right away? Anyway, then I ran this command: sudo cryptsetup luksOpen /dev/xxx xxx Then I tried copying the contents of the existing partition (call it yyy) to the encrypted one like this: sudo dd if=/dev/yyy of=/dev/mapper/xxx bs=1MB and it ran for a while, but exited with this: dd: writing `/dev/mapper/xxx': No space left on device just before writing the last MB. I take this to mean the contents of yyy was truncated when it was copied to xxx, because I have dd'd it before, and whenever I have dd'd to a partition of the exact same size, I never get that error. (and fdisk reports they are the same size in blocks). After a little Googling I discovered all luksFormat'ted partitions have a custom header followed by the encrypted contents. So it appears I need to create a partition exactly the size of the old one + however many bytes a LUKS header is. What size should the destination partition be, no. 1, and no. 2, am I even on the right track here? UPDATE I found this in the LUKS FAQ: I think this is overly complicated. Is there an alternative? Yes, you can use plain dm-crypt. It does not allow multiple passphrases, but on the plus side, it has zero on disk description and if you overwrite some part of a plain dm-crypt partition, exactly the overwritten parts are lost (rounded up to sector borders). So perhaps I shouldn't be using LUKS at all?

• Ask the Readers: What Operating System Do You Use?

  - by Mysticgeek

  The three most popular choices out there when it comes to computer operating systems, is Windows, Mac OS X, and Linux. What we want to know is…which operating system do you use? Photo by ~Dudu,,]* Computer users today have more choices than ever when it comes to the operating system they use. In the Windows world, there are three versions out there in daily use. A lot of businesses and home users use XP, completely avoided Vista, and are starting to migrate to Windows 7. While a lot of home users received their new computer with Vista pre-installed and are still using it. Others were quick to jump to Windows 7, and some don’t want to leave the comforts of XP. Desktop Linux distro’s have been consistently growing in popularity as versions like Ubuntu become more user friendly. And let us not forget the loyal Apple users who would never give up OS X. You may have to use a certain OS at the workplace, but when you get home, your options are a lot more open. And now with the ease of virtualization, it’s easy to run multiple operating systems on one machine. Each OS offers different advantages that people pick based on their needs.

• DIVIDE vs division operator in #dax

  - by Marco Russo (SQLBI)

  Alberto Ferrari wrote an interesting article about DIVIDE performance in DAX. This new function has been introduced in SQL Server Analysis Services 2012 SP1, so it is available also in Excel 2013 (which still doesn’t have other features/fixes introduced by following Cumulative Updates…). The idea that instead of writing: IF ( Sales[Quantity] <> 0, Sales[Amount] / Sales[Quantity], BLANK () ) you can write: DIVIDE ( Sales[Amount], Sales[Quantity] ) There is a third optional argument in DIVIDE that defines the result in case the denominator (second argument) is zero, and by default its value is BLANK, so I omitted the third argument in my example. Using DIVIDE is very important, especially when you use a measure in MDX (for example in an Excel PivotTable) because it raise the chance that the non empty evaluation for the result is evaluated in bulk mode instead of cell-by-cell. However, from a DAX point of view, you might find it’s better to use the standard division operator removing the IF statement. I suggest you to read Alberto’s article, because you will find that an expression applying a filter using FILTER is faster than using CALCULATE, which is against any rule of thumb you might have read until now! Again, this is not always true, and depends on many conditions – trying to simplify, we might say that for a simple calculation, the query plan generated by FILTER could be more efficient – but, as usual, it depends, and 90% of the times using FILTER instead of CALCULATE produces slower performance. Do not take anything for granted, and always check the query plan when performance are your first issue!

• Ask the Readers: Which Google Services Do You Use?

  - by Asian Angel

  Nearly everyone uses at least one of Google’s services while browsing each day. What we want to know this week is which Google services do you use? Image by adria.richards Google offers a multitude of services such as e-mail, calendar, and docs to help you manage your online life. Some of you may only use a few of the available services while others are power users. A fair number of businesses and schools have also switched over to Google apps and services for their organization. Whether it is at home, work, or both Google has become a part of our daily lives. Being able to access everything in one place can be extremely useful but equally frustrating if Google’s services experience any downtime. Another concern for some people is the issue of privacy over having so much information stored by a single company. Ultimately the final decision lies with you.

• FileOpenPicker/FileSavePicker doesn't allow *.* wildcard file associations

  - by mbrit

  On Twitter, Matthias Jauernig commented that the FileOpenPicker and FileSavePicker doesn't allow *.* wildcard file associations. I was relaxed about this and wrote back that it was related to sandboxing implying it was a "good thing", however as Matthias commented back, perhaps it's not.In Metro-style the sandboxing works that if something gives you a file (e.g. the picker, or a share operation), you can access it regardless of where on the system. If you find the file yourself, you have to declare the type.The reason why I think it's related to sandboxing is because if you work with files programmatically you have to be explicit about the file types. This is to stop malware that you think is only interested in - say .PDF files, scanning and uploading any .EML files that it can find on the machine. It follows then on the pickers that restriction would continue. It allow's the retail store team to validate that an app is likely to behave itself. If it's an app that works with images, locking down the picker so that it can only access image file types makes sense.However Matthias mentioned that he has an app that should allow files of any arbitrary file. That fits more into the "if the user selects it, it must be OK" camp than the "programmatic scanning" camp. So now I'm left wondering why the picker doesn't allow any type to be selected.I think then maybe the decision comes down to simplicity. A lot of the decisions in Metro-style design relate to ideas about "zero intimidation". Allow the user to select any file is too much like Old Windows, and not enough like Reimagined Windows. What happens in Matthias's app if the user selects Explorer.exe as the file he or she wants to work with? I guess it's fine if you expect your user to know what they're doing (Old Windows), but not so fine if you're expecting a three year old to work with it (Reimagined Windows).

• Manage Sending 2010 Documents to the Web with Office Upload Center

  - by Mysticgeek

  One of the main new features being touted in Office 2010 is the ability to upload documents to the Web for sharing and collaboration. Today we look at using Office Upload Center to help manage your uploaded documents. Microsoft Office Upload Center  When you upload an Office 2010 document to the web, a handy tool to manage them is the Office Upload Center. It’s a way to see what is being uploaded or what might have failed to reach the servers. It lets you know if a document failed to upload for some reason. In this case it looks like the incorrect credentials were entered when signing into Windows Live. Click on the Resolve button to get a list of actions you can take to get things corrected.   You can access the Upload Center from the icon which appears on the System Tray when uploading documents. Right-click the icon to control notifications, pause uploads, and access its settings. In the Settings section you can choose how Upload Center displays notifications, select the number of days to keep files in Cache, and delete currently cached files. If you find yourself uploading several documents to the web during the day, the Office Upload Center is a nice feature for managing them.

• Happy Chinese New Year!

  - by Shaun

  Today is Dec the 29th in Chinese Traditional Calendar, that means on Thursday (3rd of Feb) we will have the Chinese New Year! For those who doesn’t know about the Chinese New Year please visit the wikipedia site. This is the most important holiday not only for the Chinese in China, but the Chinese all around the world. Here I would like to say: ????. (Chun Jie Kuai Le, Happy Chinese New Year). OK I have 3 news with my celebration: The new windows azure developer portal had been published for a while and the windows azure team wants to get to know how do we think about it. Here is a survey avaiable you can send your feedback. PS, please refer to my previous blog for the features of this new site. The latest Window Azure Platform Training Kit Jan Update had been released that you can download here. There is a demo and a hands-on lab about the Windows Phone 7 application with Windows Azure avaiable which should be interesting. If you have heard about the new feature for SQL Azure named SQL Azure Federation, you might know that it’s a cool feature and solution about database sharding. But for now there seems no similar solution for normal SQL Server and local database. I had created a library named PODA, which stands for Partition Oriented Data Access which partially implemented the features of SQL Azure Federation. I’m going to explain more about this project after the Chinese New Year but you can download the source code here.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Moving from windows to linux

  - by rincewind

  I need to reconcile these 2 facts: I don't feel comfortable working on Linux; I need to develop software for Linux. Some background: I have a 10+ years of programming experience on Windows (almost exclusively C/C++, but some .NET as well), I was a user of FreeBSD at home for about 3 years or so (then had to go back to Windows), and I've never had much luck with Linux. And now I have to develop software for Linux. I need a plan. On Windows, you can get away with just knowing a programming language, an API you're coding against, your IDE (VisualStudio) and some very basic tools for troubleshooting (Depends, ProcessExplorer, DebugView, WinDbg). Everything else comes naturally. On Linux, it's a very different story. How the hell would I know what DLL (sorry, Shared Object) would load, if I link to it from Firefox plugin? What's the Linux equivalent of inserting __asm int 3/DebugBreak() in the source and running the program, and then letting the OS call a debugger? Why the hell release builds use something, called appLoader, while debug builds work somehow different? Worst of all: how to provision Linux development environment? So, taking into account that hatred is usually associated with not knowing enough, what would you recommend? I'm ok with Emacs and GCC. I need to educate myself as a Linux admin/user, and I need to learn proper troubleshooting tools (strace is cool, btw), equivalents to the ones I mentioned above. Do I need to do Linux From Scratch? Or do I need to just read some books (I've read "UNIX programming enviornment" by Kernighan and "Advanced Programming..." by Stevens, but I need to learn something more practical)? Or do I need to have some Linux distro on my home computer?

• Why I love NUnit, NCover, CC Nant and friends

  - by gregarobinson

  I have used these opensource tools on past projects in different stages, but never all of them at once. I am on a project now where there is a build server, Subversion, Nant, NUnit with 100% NCover required coverage, CrusieControl, CCTray and Rhino Mockc.I was extending an Interface and concrete class in a solution I had never worked on before today. Automatic builds were turned off for the day for a special case QA test. I added my new members to the Interface, implemented them in the concrete class, did a local build, tested, all looked good, so I did a Subversion Update then Commit.  Around 4:30PM the automatic builds were turned back on. Right away the build failed for less than 100% code coverage on my last Commit. Turns out there was a project in the solution I modified that had numerous NUnit tests on the Interface/Concrete class I modified, 3 of which now failed. Now that is cool..of course i was frustrated as i wanted to go home..but..I did a bad thing..I did not run nant on the source prior to my Commit. Lesson learned, and a great lesson at that!

• Where should I place my reaction code in Per-Pixel Collision Detection?

  - by CJ Cohorst

  I have this collision detection code: public bool PerPixelCollision(Player player, Game1 dog) { Matrix atob = player.Transform * Matrix.Invert(dog.Transform); Vector2 stepX = Vector2.TransformNormal(Vector2.UnitX, atob); Vector2 stepY = Vector2.TransformNormal(Vector2.UnitY, atob); Vector2 iBPos = Vector2.Transform(Vector2.Zero, atob); for(int deltax = 0; deltax < player.playerTexture.Width; deltax++) { Vector2 bpos = iBPos; for (int deltay = 0; deltay < player.playerTexture.Height; deltay++) { int bx = (int)bpos.X; int by = (int)bpos.Y; if (bx >= 0 && bx < dog.dogTexture.Width && by >= 0 && by < dog.dogTexture.Height) { if (player.TextureData[deltax + deltay * player.playerTexture.Width].A > 150 && dog.TextureData[bx + by * dog.Texture.Width].A > 150) { return true; } } bpos += stepY; } iBPos += stepX; } return false; } What I want to know is where to put in the code where something happens. For example, I want to put in player.playerPosition.X -= 200 just as a test, but I don't know where to put it. I tried putting it under the return true and above it, but under it, it said unreachable code, and above it nothing happened. I also tried putting it by bpos += stepY; but that didn't work either. Where do I put the code?

• IIM Calcutta &ndash; EPBM 14 &ndash; Campus Visit &ndash; Day 1 &ndash; Registration &amp; Beginning

  - by Ram Shankar Yadav

  Hey Guys! I’m back with the updates, it was an awesome Monday morning, for me it started when Sun came on my face, and the time was 5:30AM~~ I was amazed that this part of the country gets the sunrise quite early, but I ignored the sunlight for a while by covering my face, but…finally the door knocked….~ It was Mukesh, and the time was 6 AM, so I thought let’s get rid of laziness and start my day~ After having my brush and bath, I shaved and we headed for the Breakfast~ We quickly had our bread butter jam combo, and left for the Auditorium for Registration~ We searched for our names and signed the Registration paper and got a cool IIM C bag, with following in it: - a IIMC Notepad - Cello X Caliber pen - a book “What the Best MBAs Know”, and - Reading Material for Campus Sessions Today we had lectures on “Evolution of Indian Corporate Sector” (2 Session of 1.5 hrs each) and “Indian Economy: Crisis & Response” (2 Sessions of 1.5 hrs). “Evolution of Indian Corporate Sector” was by Prof. Raghabendra Chattopadhyay, was one of my best lectures I’ve ever attended in my life, he started with a question that saying that “The Indian Capitalists didn’t wanted the economy to open up till the economic reforms occurred?”, he is one of the best story tellers I’ve ever met, he started with the ancient European and Indian history and linked the trade & economics with it, simply amazing~ I can’t believe I didn’t get bore even after a 2hour long session…awesome~~ Afterward we had our lunch break, we did our lunch in “New Hostel” building and got back for “Indian Economy” sessions. Indian Economy session was taken by Sudip Chaudhuri, for us he’s a well known face as we have already attended his sessions on Macroeconomics~ It was an interactive, easy going, and a laughable session, and we did discussed some serious issues as well. After the class got over we went out and got few T-Shirts and Mugs for ourselves, and yep not to forget it “Rained” in Kolkata today~~ We got back and had our dinner and dispersed finally… I loved this amazing Monday, and hope the spirit continues till Saturday~ I’m feeling the enrichment in my thought and perceptions~ I’m lovin’ it~~ ram :)

• Why does Farseer 2.x store temporaries as members and not on the stack? (.NET)

  - by Andrew Russell

  UPDATE: This question refers to Farseer 2.x. The newer 3.x doesn't seem to do this. I'm using Farseer Physics Engine quite extensively at the moment, and I've noticed that it seems to store a lot of temporary value types as members of the class, and not on the stack as one might expect. Here is an example from the Body class: private Vector2 _worldPositionTemp = Vector2.Zero; private Matrix _bodyMatrixTemp = Matrix.Identity; private Matrix _rotationMatrixTemp = Matrix.Identity; private Matrix _translationMatrixTemp = Matrix.Identity; public void GetBodyMatrix(out Matrix bodyMatrix) { Matrix.CreateTranslation(position.X, position.Y, 0, out _translationMatrixTemp); Matrix.CreateRotationZ(rotation, out _rotationMatrixTemp); Matrix.Multiply(ref _rotationMatrixTemp, ref _translationMatrixTemp, out bodyMatrix); } public Vector2 GetWorldPosition(Vector2 localPosition) { GetBodyMatrix(out _bodyMatrixTemp); Vector2.Transform(ref localPosition, ref _bodyMatrixTemp, out _worldPositionTemp); return _worldPositionTemp; } It looks like its a by-hand performance optimisation. But I don't see how this could possibly help performance? (If anything I think it would hurt by making objects much larger).

• So, whats the best book on C#?

  - by mbcrump

  I see this question several times a day from newbie’s to professionals. I have listed the best C# books that I have read so far.   ECMA-334 C# Language Specification. – FREE book. This is probably the best place to start. Read it backwards and forwards and you can even request a hard copy. Absolute Beginners Guide to C Sharp 2nd Edition – Used this early on and found it very useful even if its game programming. C-Sharp 2.0 - The Complete Reference, 2nd Edition (McGraw-Hill, 2006) – One of the most useful books that is always with me. It contains short example code and is very well written. Dot Net Zero - Charles Petzold  - FREE book and you should definately give it a read. C Sharp in Depth by Jon Skeet -  Probably one of the most in depth books on C Sharp and definitely not for beginners. Jon Skeet knows C# like no other. I would consider this book the Bible of C#. If you understand 50% of this book, you have a good understanding of the language.  CLR via C Sharp 3rd Edition – I just started reading this book and it is another book thats not for beginners. If you really want to understand the CLR then give this book a try. Well, thats it. I hope you enjoy the books as I have spent a lot of time researching different C# books.

• Almost at our first year anniversary!

  - by Vizioz Limited

  It has been a hectic first year at Vizioz and things are still going from strength to strength. 11 months ago I started Vizioz with zero capital investment in the middle of a recession, which to some may seem a daunting prospect but to others including myself it was the challenge I needed to make me want to get up in the morning :) I wanted to prove that even in the curent financial climate it is still possible to start a new business.We are still experiencing the normal growing pains of a small business but this is something we just need to work our way through, it is amazing how much paperwork and administration there is running a small business, office admin, insurance, vat and for the last few months PAYE.For the last 9 months we have shared an office with another small business called Little Big Ideas. They are a design agency working across a broad spectrum of design from branding, print and digital. Last month we decided to move offices to a larger office and now have room for 8 of us, so now we need a couple more clients to help produce enough work to fill the space and grow to the next level.As well as moving office 2 months ago I blogged about my first employee Colin starting work for me, he has picked up Umbraco very well and has mastered the art of good CSS design, as the majority of our clients are large multi-nationals they still require support for IE6 which as all web developers know is the nightmare of all web browsers.This month has seen the next step in the growth of Vizioz as I have taken on another PhD graduate called Pricilla, welcome to the team!This month we plan to launch our own website to enable us to showcase some of the sites we have built over the past 11 months and to allow potential clients to see what we can offer. We might still be relatively small but we have some great case studies to show and with two PhD graduates on the team we have great talent capable of producing complex and innovative solutions for our clients. As soon as we have launched out new website I will blog again about what the future holds for Vizioz and what we can offer our prospective clients as well as e obvious Umbraco CMS solutions.

• Panning with the OpenGL Camera / View Matrix

  - by Pris

  I'm gonna try this again I've been trying to setup a simple camera class with OpenGL but I'm completely lost and I've made zero progress creating anything useful. I'm using modern OpenGL and the glm library for matrix math. To get the most basic thing I can think of down, I'd like to pan an arbitrarily positioned camera around. That means move it along its own Up and Side axes. Here's a picture of a randomly positioned camera looking at an object: It should be clear what the Up (Green) and Side (Red) vectors on the camera are. Even though the picture shows otherwise, assume that the Model matrix is just the identity matrix. Here's what I do to try and get it to work: Step 1: Create my View/Camera matrix (going to refer to it as the View matrix from now on) using glm::lookAt(). Step 2: Capture mouse X and Y positions. Step 3: Create a translation matrix mapping changes in the X mouse position to the camera's Side vector, and mapping changes in the Y mouse position to the camera's Up vector. I get the Side vector from the first column of the View matrix. I get the Up vector from the second column of the View matrix. Step 4: Apply the translation: viewMatrix = glm::translate(viewMatrix,translationVector); But this doesn't work. I see that the mouse movement is mapped to some kind of perpendicular axes, but they're definitely not moving as you'd expect with respect to the camera. Could someone please explain what I'm doing wrong and point me in the right direction with this camera stuff?

• Constructor vs setter validations

  - by Jimmy

  I have the following class : public class Project { private int id; private String name; public Project(int id, String name, Date creationDate, int fps, List<String> frames) { if(name == null ){ throw new NullPointerException("Name can't be null"); } if(id == 0 ){ throw new IllegalArgumentException("id can't be zero"); } this.name = name; this.id = id; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } } I have three questions: Do I use the class setters instead of setting the fields directly. One of the reason that I set it directly, is that in the code the setters are not final and they could be overridden. If the right way is to set it directly and I want to make sure that the name filed is not null always. Should I provide two checks, one in the constructor and one in the setter. I read in effective java that I should use NullPointerException for null parameters. Should I use IllegalArgumentException for other checks, like id in the example.

• Will HTML5/JS Eventually Replace All Client Side Languages? [closed]

  - by Shnitzel

  I'm just wondering about the future of it all. IMHO, there are 4 forces that define where technology goes: Microsoft, Apple, Google, Adobe. It looks like in Apple's iPhone/iPad iADs can now be programmed in HTML5. So does that mean HTML5 will eventually replace objective-c? Also, Microsoft has now shifted it's focus from WPF/Silverlight to HTML5 and I assume Visual Studio 2011 will be all about tooling support for HTML5. Because that's what Microsoft do. (Tools). In a few months IE9 the last major browser will support HTML5. Similarly Adobe is getting on the HTML5 bandwagon and allows to export flash content to HTML5 in their latest tools. And we all know how much in bed Google is with html5. Heck, their latest Operating System (Chrome OS) is nothing but a big fat web browser. Apps for Mobile (i.e., iPhone, Android, WM7) are very hard for a company to program especially for many different devices (each with their own language) so I'm assuming this won't last too long. I.e., HTML5 will be the unifying language. Which is somewhat sad for app developers because now users will be able to play the "cool" html5 apps for free on the web and it'll be hard to charge for them. So are strongly-typed languages really doomed, and in the future, say 5-10 years, will client side programming only be in HTML5? Will all of us become javascript programmers? :) Because the signs are sure pointing that way...
