• SSL Certificate

  - by outdoorcat

  I've received the email below from google about my wordpress site and have no idea how to follow the instructions. Any help out there? Dear Webmaster, The host name of your site, https://www.example.com/, does not match any of the "Subject Names" in your SSL certificate, which were: *.wordpress.com wordpress.com This will cause many web browsers to block users from accessing your site, or to display a security warning message when your site is accessed. To correct this problem, please get a new SSL certificate from a Certificate Authority (CA) with a "Subject Name" or "Subject Alternative DNS Names" that matches your host name.

• About floating point precision and why do we still use it

  - by system_is_b0rken

  Floating point has always been troublesome for precision on large worlds. This article explains behind-the-scenes and offers the obvious alternative - fixed point numbers. Some facts are really impressive, like: "Well 64 bits of precision gets you to the furthest distance of Pluto from the Sun (7.4 billion km) with sub-micrometer precision. " Well sub-micrometer precision is more than any fps needs (for positions and even velocities), and it would enable you to build really big worlds. My question is, why do we still use floating point if fixed point has such advantages? Most rendering APIs and physics libraries use floating point (and suffer it's disadvantages, so developers need to get around them). Are they so much slower? Additionally, how do you think scalable planetary engines like outerra or infinity handle the large scale? Do they use fixed point for positions or do they have some space dividing algorithm?

• How do I plot individual pixels using the XNA APIs?

  - by izb

  If I wanted to fill my game screen with individually coloured pixels, how would I do this? For example, if I wanted to write a 'game of life'-type game where each pixel was a cell, how would I achieve this using XNA? I've tried just calling SetData() on a Texture2D object using a screen-sized array of Color values, but it complains with: You may not call SetData on a resource while it is actively set on the GraphicsDevice. Unset it from the device before calling SetData. How do I do as it asks? Or better still... is there an alternative, better, efficient way to fill a screen with arbitrary pixels?

• Les processeurs multi-cores pourraient gagner en performances, grâce à des communications internes six fois plus rapides

  Les processeurs multi-cores pourraient gagner en performances, grâce à des communications internes six fois plus rapides Des chercheurs américains, de l'Université de la Caroline du Nord, on fait une découverte qui pourrait améliorer les performances des puces multicores. En effet, la majorité des processeurs actuels de 4 ou 8 coeurs, connaissent des difficultés à voir leurs cores communiquer directement entre eux. Mais une alternative serait possible. Au lieu de devoir passer par la mémoire pour envoyer et récupérer des données, plusieurs coeurs travaillant sur la même tâche pourraient bénéficier d'une accélération matérielle. En effet, les ingénieurs développant le projet ont mis au point une HAQu (h...

• Is MVC now the only way to write PHP?

  - by JasonS

  Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

• Path vs GeometryDrawing

  - by Carlo

  Just wondering what's lighter, I'm going to have a control that draws 280 * 4 my SegmentControl, which is a quarter of a circle, and I'm just wondering what's the way that takes least memory to draw said segment. GeometryDrawing: <Image> <Image.Source> <DrawingImage> <DrawingImage.Drawing> <GeometryDrawing Brush="LightBlue" Geometry="M24.612317,0.14044853 C24.612317,0.14044853 33.499971,-0.60608719 41,7.0179795 48.37642,14.516393 47.877537,23.404541 47.877537,23.404541 L24.60978,23.401991 z" /> </DrawingImage.Drawing> </DrawingImage> </Image.Source> </Image> Or Path: <Path Fill="LightBlue" Stretch="Fill" Stroke="#FF0DA17D" Data="M24.612317,0.14044853 C24.612317,0.14044853 33.499971,-0.60608719 41,7.0179795 48.37642,14.516393 47.877537,23.404541 47.877537,23.404541 L24.60978,23.401991 z" /> Or if you know of an even better way, it'll be much appreciated.

• Strange problem with VSS: VSS doesn't work after 5 p.m.

  - by afsharm

  I have a very strange problem with Visual Source Safe. I use VSS as a add-on with VS 2008 in a corporate intranet with 5 other colleagues. My VS stops working after 5 p.m. most of days with complaining can not connect Source Safe. I'm running VS 2008 and VSS 2005 on Vista and no other one in corporate have such a problem. What do you think about its cause? Is there any log for VSS?

• When to use functional programming approach and when not? (in Java)

  - by john smith optional

  let's assume I have a task to create a Set of class names. To remove duplication of .getName() method calls for each class, I used org.apache.commons.collections.CollectionUtils and org.apache.commons.collections.Transformer as follows: Snippet 1: Set<String> myNames = new HashSet<String>(); CollectionUtils.collect( Arrays.<Class<?>>asList(My1.class, My2.class, My3.class, My4.class, My5.class), new Transformer() { public Object transform(Object o) { return ((Class<?>) o).getName(); } }, myNames); An alternative would be this code: Snippet 2: Collections.addAll(myNames, My1.class.getName(), My2.class.getName(), My3.class.getName(), My4.class.getName(), My5.class.getName()); So, when using functional programming approach is overhead and when it's not and why? Isn't my usage of functional programming approach in snippet 1 is an overhead and why?

• Unable to install 12.10 on asus r500v

  - by bmdr38

  I have been unable to get beyond the grub boot screen of the live dvd/usb. The Try Ubuntu without installing, Install Ubuntu, etc menu shows, and I have tried adding/replacing nomodeset and no splash with neither helping. Even "Check disc for defects" does not display anything when selected. I am at a complete loss as to how to fix this one. I have had many successful installs in the past, but this is definitely a first for me. Just as FYI, Gfx card: Geforce GT 635M I realize this particular card has Optimus on it, however even the alternative boot/command line install fails to load. Any help would be appreciated. I realize there have been multiple threads on this, but none of the methods within them have solved this yet. Thanks

• Will there be IQueryable-like additions to IObservable? (.NET Rx)

  - by Jason

  The new IObservable/IObserver frameworks in the System.Reactive library coming in .NET 4.0 are very exciting (see this and this link). It may be too early to speculate, but will there also be a (for lack of a better term) IQueryable-like framework built for these new interfaces as well? One particular use case would be to assist in pre-processing events at the source, rather than in the chain of the receiving calls. For example, if you have a very 'chatty' event interface, using the Subscribe().Where(...) will receive all events through the pipeline and the client does the filtering. What I am wondering is if there will be something akin to IQueryableObservable, whereby these LINQ methods will be 'compiled' into some 'smart' Subscribe implementation in a source. I can imagine certain network server architectures that could use such a framework. Or how about an add-on to SQL Server (or any RDBMS for that matter) that would allow .NET code to receive new data notifications (triggers in code) and would need those notifications filtered server-side.

• Unable to delete file locked by same process -- weird!

  - by user300266

  I have an application written in PHP that uses a COM dll written in C#. The dll creates an image file by combining two other image files. The PHP script then takes over to do the housekeeping tasks of deleting the two source files and renaming the resulting combined file. The problem is the PHP script can't delete one of the source files because it's locked. The weird thing is that the process that has it locked is itself which in this case is the Apache Web Server. I have tried altering the C# dll to dispose of all bitmap and graphics objects prior to exiting, and yet the lock remains. My question is, what can I do to get the dll to let go and release the file locks. This is very frustrating.

• Is it possible to exclude some files from checkin (TFS) ?

  - by Thomas Wanner

  We use configuration files within various projects under source control (TFS), where each developer has to make some adjustments in his local copy to configure his environment. The build process takes care about replacing the config files with the server configuration as a part of the deployment, so it doesn't actually matter what is in the repository. However, we would anyway like to keep some kind of a default non-breaking version of config files in the repository, so that e.g. people not involved in the particular project won't run into troubles because of local misconfiguration. We tried to resolve this by introducing the check-in policy that simply forbids to check-in the config files. This works fine, but just because we're lazy to always uncheck those checkboxes in the pending changes window, the question comes : is it possible to transparently disable the check-in of particular files without keeping them out of source control (e.g. locking their current version) ?

• Why acegi (Spring Security) converts password to uppercase before comparing ?

  - by Tony

  One of my colleague in QA team reported a bug to me, the bug said that can't change password to lowercase, otherwise login is rejected,using number or uppercase is all fine. The login system was implemented using acegi 1.0 (now called Spring Security). This was a very strange bug,changing password is done by encrypting the user input string into MD5 string, I implemented this without using anything related acegi, I don't if the is the origin cause of the problem. When the login is rejected, through debugging, I find that, the user input is converted into uppercase by acegi when passing to the acegi comparing logic. At first, I didn't believe this, when I checkout the acegi source and debugging with it, I find it does convert both username and password to uppercase (source code line 121), Can you tell me why it does this? This can cause password encoding mismatch!

• Xcode Tips for Eclipse users?

  - by willcodejavaforfood

  Hi, I've been slowly working my way through the examples in Beginning iPhone Development and there are a few things that I have not been able to figure out, but I'm sure you guys can help me with it. In Eclipse there is a Source-Generate Getters/Setters, can you do something similar to synthesize properties in Xcode I also cannot seem to find a Refactor menu I'm also struggling to find the equivalent to Source-Override/Implement Methods --Edit-- I failed to describe my problem it seems. I do know that synthesizing properties will generate getters/setters for me, but I am looking for a way to generate the @property/@synthesize code, by selecting the variables. Short list to start with, but I will probably have more as my confusion grows in might. :)

• Le H.264 est de retour sur Chrome, qui pourra lire les vidéos dans ce format grâce à une extension de Microsoft

  Le H.264 est de retour sur Chrome, qui pourra lire les vidéos dans ce format grâce à une extension de Microsoft Mise à jour du 03.02.2011 par Katleen Il y a un petit peu moins d'un mois, Google annonçait la fin du support du codec H.264 par son navigateur Chrome, ce qui en enchantait certains et en gênait d'autres. Aujourd'hui, une alternative est possible, grâce à Microsoft (qui s'était déjà occupé du problème sous Firefox). L'éditeur de Redmond vient ainsi de dévoiler son "Windows Media Player HTML5 Extension for Chrome", qui, comme son nom l'indique, est une extension pour Chrome qui permettra la lecture de vidéos au format H.264 par les utilisateurs du navigateur d...

• Streaming content from (sharepoint) web part

  - by Mikko Rantanen

  How does one stream files, html or custom AJAX responses from web parts? Our current quick-and-very-dirty solution is to make the web part call the current page with certain query parameters, which the web part checks and instead of performing normal load it writes the required things to output and calls response end. This sounds bad since SharePoint might load other web parts and execute their code before reaching our web part. The web part is configured with data source settings which means the streaming context must be specific to the web part so it can acquire the correct data source settings.

• Is wikipedia a valuable resource for studying data structures? (can we call it complete?)

  - by Amir Nasr

  Can I depend on wikipedia to learn data structures fully using the list of data structures http://en.wikipedia.org/wiki/List_of_data_structures and the links they refer to? The same question for algorithms http://en.wikipedia.org/wiki/List_of_algorithm_general_topics ?... What's after learning algorithms and data structures? Specializing in a certain field of algorithms such as computer graohics, memory management...etc? or what could be the plan for mastering programming after knowing the language syntax and the background about program design and programming logic? I asked about wikipedia because i would like to find a complete resource or are least a resource which would be enough for the field of data structures instead of searching for separate articles in different places in other words an alternative to books which may even be more complete.

• What ASP.NET MVC project files should I not add to Subversion

  - by Dan

  this is likely a naive question, but I want to do this right the first time. I have a MVC solution which has the following: Data project - C# Services project - C# MVC Web Project - ASP.NET MVC Test Project Currently, I am using the MVC2 source as a means to debug my own code. I do not plan on checking that in, but I realize once I go back to the MVC2 DLL, my solution will change. I'm pretty sure I just shouldn't check in stuff that changes with each build: the bin folder on the Web project, for example. Is there a list of what not to commit to source control? :)

• Trying to update Asus BIOS: FreeDOS crashes

  - by ZekeDroid

  My UX31 zenbook is experiencing some weird shutdown behavior when the battery drops below 50% and the internet seems to agree that updating the BIOS is a good step forward since there were issue with the kernel before. I downloaded both the correct BIOS file and the windows 7 utility tool and now need to boot FreeDOS to run, however, I've tried every method out there and they all fail (or so I think): Using unetbootin's FreeDOS 1.0 image I get to an error saying it couldn't run drivers then I get to a command line on disk A:. I assumed a dead end. Using unetbootin but with the FreeDOS 1.1 version image downloaded directly: get an error of "bad or missing command interpreter". I looked online and the solutions didn't work either. So, is there an alternative to FreeDOS or to installing a BIOS that I could use?

• Inexpensive Business Checks

  - by Randy Walker

  One of the most annoying things when setting up a business is paying the outrageous fees for business checks.  When starting out, rather than pay the $150 for the handful of computer printable checks, I had bought software that would create the checks for me.  But if you didn’t know, those little digits at the bottom of a check are magnetically encoded and requires special ink. Fortunately, my current bank has one of the best bill pay websites, so I have exclusively used it.  But since I recently had to open a new bank account, I went off in search of a cheap alternative for business checks.  A bit wary of some of the printers, I opted for TechChecks and was extremely surprised a few days later when my checks arrived in perfect condition.  (I recommend the diamond prismatic red-blue-green checks.  Beautiful and very professional looking.) It was perfect timing as well, since I now have to reorder some checks for another account.

  Hi guys i have a bit of a problem with a few classes, and i would be very grateful if someone can help me out. So i have: Already compiled executable (for whom i don't have the source) A class in that program that i want to call The program doesn't have export for the class, and that's my problem i don't have definition for this class, so is there a way to get a callback to this class? Example: In the compiled executable: foo::bar (example) { printf(example); } My app: CALLBACK(foo::bar, "this text must be passed as argument") Or in other words i want to call a class in other executable (without having its source) and pass arguments to its function.
