• Apress Deal of the Day - 22/Feb/2010 - Entity Framework 4.0 Recipes: A Problem-Solution Approach

  - by TATWORTH

  Todays $10 deal from Apress at  http://www.apress.com/info/dailydeal is "Entity Framework 4.0 Recipes: A Problem-Solution Approach" Whilst I am still wary of using the Entity framework and I would caution against its use for updates in financial systems, unless you use a technique such as you can find on pages 509-512 of this book. This book is very impressive as I found the answer to this in about 2 minutes from the time I downloaded the e-book. Entity Framework 4.0 Recipes: A Problem-Solution Approach With this book, you will learn the core concepts of Entity Framework through a broad range of clear and concise solutions to everyday data access tasks. Armed with this experience, you will be ready to dive deep into Entity Framework, experiment with new approaches, and develop ways to solve even the most difficult data access challenges. $49.99 | Published May 2010 | Larry Tenny

• Not sure which Ubuntu to install (64 or 32 bit)

  - by user285993

  I want to use Ubuntu. I have Win 7 Home Premium 32-bit right now... I used to have 64 on this laptop (Toshiba Satellite c650) but my disc got a ring of death. Intel Penium CPU B940 2.00GHz, 4GB RAM Also, I'm guessing I need an image mounter such as PowerISO to install Ubuntu, if I don't have a DVD lying around that I can mount to? I'm a noob. Thanks for your help, in advance. EDIT: My question wasn't clear... can my processor and RAM handle 64-bit Ubuntu? Hell of a lot nicer than Win7

• Are people getting away with the "follow 1000s and then unfollow" Twitter trick? [closed]

  - by Baumr

  It seems that more and more people are trying to 'cheat' their way into more Twitter followers. The basic mechanism is: Follow thousands of people on Twitter with the hope that they'll follow you back. Once it reaches a point you're happy with, start gradually unfollowing them. That way, at the end of the day, it'll look like a lot of people follow you unconditionally. I've seen self-proclaimed social media and SEO experts do this. It's clear they want to look influential — and will use black hat social media tactics to do so. I can see how it can work, so is Twitter letting them get away with it? Should it?

• How to design an interface, where things need to be called in a specific sequence?

  - by Vorac

  The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

• Which is the appropriate content-type meta tag value ?

  - by Argoron

  I have a question about the meta tag content-type. When starting to build my site (HTML+PHP+JS), I copied a lot of the meta tags over from elsewhere, and I have, amongst others, the following: <meta http-equiv="content-type" content="application/xhtml+xml; charset=iso-8859-1" /> Now, I've seen that tag is being used a lot with the value "text/html". I've been searching the web but could not find a comprehensive explanation regarding what the difference between both is. The "text/html" intuitively sounds more straightforward to me. Should I change my tag to that, or might the "application/xhtml+xml" be an equivalent solution ? Alternatively, can anyone point me to a resource where the different values for these tags are listed and explained in a clear manner? Thanks in advance

• How should I define my Java Objects?

  - by HonorGod

  I have a data grid where I sort of show the following information - All Guests Total Adults = 22 Total Children = 27 Confirmed Total Adults = 9 Total Children = 13 Country = Germany Total Adults = 5 Total Childres = 6 Friends Adults = 2 Children = 2 Relatives Adults = 3 Children = 4 Country = USA Total Adults = 4 Total Childres = 7 Friends Adults = 2 Children = 5 Relatives Adults = 2 Children = 2 Tentative Total Adults = 13 Total Children - 14 Country = Australia Total Adults = 7 Total Childres = 8 Friends Adults = 2 Children = 3 Relatives Adults = 5 Children = 5 Country = China Total Adults = 6 Total Childres = 6 Friends Adults = 2 Children = 4 Relatives Adults = 4 Children = 2 And in the database what I have is data at the lowest level which is Friends / Relatives and the corresponding countries set as a look-up value which in indirectly connected to another look-up that can tell me if they fall under confirmed or tentative. I guess my question is how do I layout my Java Object and perform the aggregations and give it back to the client. I am not sure if I am clear with my question, but feel free to comment so I can update the question accordingly.

• Entity Framework, Code First: where is the database?

  - by Marko Apfel

  With Entity Framework 5 in Visual Studio 2012 the code first feature could let you come to the question “Where is the automatically created database located?” I run in the question after changing the model which throws during the next run this error: “The model backing the 'MyContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).” Okay – clear I thought “delete the database”. But where is the database and what type is it??? In this constellation the frameworks generates a localDB. You could access this database via SQL Server Object Explorer. For the first time you have to add this localDB. The server name is “(localdb)\v11.0”: And so we could browse through the content of this database. It got the same name like the context class.

• *raine Trip Report (Lorraine & Ukraine)

  - by delabassee

  Last week, I had the opportunity to talk about Java EE 7 in Nancy (Lorrraine - France) and Kiev (Ukraine). The first event was arranged by the local Lorraine JUG while the second one was a largest conference organised by the Ukraine Java User Group. Based on the overall feedback and discussions I had during those two events, it is clear that the WebSocket API (JSR 356) is really a hot topic. And travel issues aside, I have really enjoyed my time during those two events. Thanks to both JUGs for having me! A more detailed report can be found on my personal blog.

• What would be a good way to request comments?

  - by WarpEnterprises

  In the project/team I'm working the frequency of comments is a little low. One reason might be that it is not clear to the long-time devs what lines in the code really needs a comment (each part of the project has quite fixed devs). To increase this we plan to let team members review the code and check in "requests for comments", which the main dev of that part should replace with useful comments. Do you think this could work? If "yes": what tags should we use to mark? (e.g. //TODO please comment) Can you think of alternatives for this process? Edit: I appreciate your answers about best practice in commenting and writing code, and I completey agree. But my question targets the cases where refactoring is not an option (not wanting to change working code, not wanting to "accuse" main dev of producing code that needs refactoring,...) - so only more or better comments are an option (at least for this question).

• What do I need to do when installing old version of ubuntu on new arch platform?

  - by Blangero

  I got a board with aptio cpu which is said to be of new platform and may have driver problems while using old version of ubuntu, and it do have. After installing my customized Live ubuntu server with X(the system runs as a liveCD), X starts but failed to get right resolution. If I run ubiquity in the live system to install the system to my disk, I can't start X and the whole console was a mess.Tried connect from ssh and upgrade, failed to solve the problem. Install ubuntu 12.04.2 desktop, at bootup the text was a mess, X starts and still could not get the right resolution. Install ubuntu 14.04 server, at bootup the text was also a mess, but it turned clear and the resolution is right. So what else do I need to provide? CPUInfo ? lspci -nn | grep VGA ? anything else? And what's the problem? What can I do to support the newest arch in my customized system? Thanks

• How to upgrade to R 3.0.1 in Raring Ringtail?

  - by ACD

  I need to install the new version of R to get around the 2^31 object size limit. Its not clear how to do so. I see that there is a user-contributed PPA here. But I'm not sure exactly how to install it -- I would add the PPA, then do sudo apt-get install R-base? Do I need to manually remove the old version? How do I make sure that the new version of R plays well with Rgedit, which I use as an editor? I see many packages built for the PPA, but I don't see ALL of them, and in particular it is missing many that I use. Can I upgrade without creating problems along the lines of the worries described above? How do I do it?

• Is it possible to boot without mounting /home?

  - by Exeleration-G

  I want to backup my /home partition on /dev/sda6 using partclone, a command line utility. To do so, I first have to unmount the partition that I want to backup. Most of the time, this is easy, but /home is used by so many processes that it can't be unmounted without first killing all those processes. So, the thing I'm looking for is a way to boot Ubuntu, without mounting /home, so I can back up the not-mounted /dev/sda6 partition. Is that possible? To be clear, it would be nice if this special boot could be 'one-time-only'. So I'm not looking for ways to change /etc/fstab in such way that /dev/sda6 won't be mounted. That's because that would require me to change /etc/fstab twice each time just to make a backup. I'm aware of the fact that there are other backup solutions available, such as deja-dup. I'd like to use partclone, though.

• How to log frame times in an existing OpenGL game? [on hold]

  - by J Collins

  I have been using FRAPS for some time to benchmark instantaneous frame rates in an OpenGL game for which I am creating maps. Until recently it had been quite reliable. Now however, the bench marking shortcut has been unresponsive and I can't explain why. Ideally I could have a logging system automatically start logging whenever the game had focus, but can't find a good tool to do so. So option a) find out how to make FRAPS reliable again or b) find a new tool. Could one of you kind folks help me? Edit: Concise questions Is there a widely recognised tool to log frame drawing times and rates for compiled applications? If the answer is universally the FRAPs tool, are there any clear cases in which logging will not or should not be expected to work?

• Custom Request Templates

  - by Seth P.

  What kind of information do you require from the project management team before you can proceed on a project? Is there a certain format they utilize on Programming Requests which helps you to understand exactly how the development team can succeed with this project. Example: I always like it when project managers mock up forms. It helps significantly to know how they are visualizing the UI for many tasks. Any suggestions on how we can assist the Project Management team in issuing Programming Requests that are as clear as day will be greatly appreciated. Thanks.

• Access Denied

  Surely, now that PowerPivot has led the way, it is time for Microsoft to offer a new RAD package for database application development; namely an Excel-based front end for SQL Server Express. In that way, we'll have a powerful and familiar front end, to a scalable database, and a clear upgrade path when an app takes off and needs to go enterprise....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Fixing a bug that has never caused a problem until now.

  - by codeelegance

  I recently made a change that caused some code to be run far more often than it used to. This lead to the discovery of a bug. This bug had the potential to happen any time that code was run but because it was run so seldom it never surfaced. When I brought this to the lead developer's attention he wanted me to undo the change that exposed the bug rather than fix the bug quoting the adage, "If it ain't broke, don't fix it". Its clear to me that we were just lucky up until now but he won't listen to reason. Should I fix it anyway? Update The lead technically doesn't have any authority over me. Just tenure. He's been the sole developer on the project for a number of years until a year ago and I think he doesn't take constructive criticism very well. For what's worth, I didn't criticize him I just pointed out that just because the bug never showed up didn't mean it wasn't there.

• Is it better to use preprocessor directive or if(constant) statement?

  - by MByD

  Let's say we have a codebase that is used for many different costumer, and we have some code in it that relevant only for costumers of type X. Is it better to use preprocessor directives to include this code only in costumer of type X, or to use if statement, to be more clear: // some code #if TYPE_X_COSTUMER = 1 // do some things #endif // rest of the code or if(TYPE_X_COSTUMER) { // do some things } The arguments I can think about are: Preprocessor directive results in smaller code footprint and less branches (on non-optimizing compilers) If statements results with code that always compiles, e.g. if someone will make a mistake that will harm the irrelevant code for the project he works on, the error will still appear, and he will not corrupt the code base. Otherwise he will not be aware of the corruption. I was always been told to prefer the usage of the processor over the usage of the preprocessor (If this is an argument at all...) What is preferable - when talking about a code base for many different costumers?

• GPL exception that allows linking to free licenses only?

  - by fNek

  There is the GPL license and the linking exception which allows closed-source programs to use the program as a library. There is also the slightly more restrictive LGPL (more restrictive than GPL with exception since it requires that the user can change the library in the resulting project, etc.). And there is the Cygwin exception that allows linking to open source programs. I see clear advantages: Open-Source programs may use the library. People may use these programs for closed-source programs, but then they lose the permission to use the (GPL) library. However, there are two things I don't like about the Cygwin exception: - Its legal status is disputed - I keep hearing that it is basically worthless - It requires certification by the OSI, I would rather have certification by FSF Is there an exception to the GNU General Public License that meets my requirements?

• How does a linked library combined with the main executable program file interact with a kernel?

  - by I ask Questions For a Reason

  I was attempting to find an answer to this, and I did to some degree, but definitely not anywhere good enough to form a respectable, sensible and clear answer. If I am using Windows, Mac, Linux, or nearly any modern made OS for desktop IBM-compatible PCs, laptops, even tablets and smartphones, there's virtual memory. Clearly, compiling, at least on Windows I know this, an executable object file, such as a simple C "Hello World" output to a terminal, will be linked with the standard library, and several other Window's system software, dynamic linked libraries, and the like. However, how does linking all of these executables together or resources form a connectable interaction with, say, a device driver or any other stuff on the lower level?

• Screen tearing (very noticable during video playback) with HD3000 AND HD Radeon 6630m

  - by NilRecurring

  I did not have this issue with Ubuntu 11.10. Well, to be clear, I did, but it was easily remedied with compiz workarounds. I have tried both the propriety and open source ati drivers, and the intel HD 3000 (as far as I know) should be part of the Kernel already. So I am pretty much 100% stumped given my general lack of Linux knowledge. I really enjoy this OS, would hate to have to return to Windows (read: HATE) because of something as trivial as video playback. Some details: Lenovo Thinkpad Edge e520 Intel HD 3000/AMD HD Radeon 6630m Ubuntu 12.04 64bit.

  Here's a slide show that's paraphrasing Cameron Purdy's presentation on how Java technology has and hasn't supplanted C++. See: Why Java Has/Hasn't Won vs. C++ Here's a quote: This eWEEK slide show borrows from Purdy’s arguments and looks at 10 reasons Java was able to supplant C++, as well as five reasons or areas it was not. It's like Godzilla vs. Mechagodzilla. Can there really be a clear winner? Well, stick around and watch Godzilla vs. Mechagodzilla II on tomorrow's The 4:30 movie as Monster Week continues on WABC, and find out... Hinkmond

• knetworkmanager not starting at all

  - by yoshi

  It seems that my knetworkmanager is not starting anymore. Read: In KDE4's sys tray I don't have a icon to manage my networks. Also when starting it from terminal or kick off menu literally "nothing" happens. I don't know what's wrong with it. Sadly after reading this answer on superuser.com it seems I can not connect to wifi via iwconfig 'cause my network is WPA2 encrypted. (Basically I can not set they passphrase - invalid argumenterror.) So it seems I've to get knetworkmanger running again as I also can't download other tools. I've tried stuff like sudo service network-manager restart but it didn't seem to help. I'm kinda puzzled so any help for this would be appreciated. PS: If it hasn't become clear: The whole drama of is simply I can't connect to wifi and internet :o)

• How to Do htaccess 301 Redirect from Old Filename Pattern to New Filename Pattern?

  - by user249493

  I have a bunch of old files prefixed with "old-" (e.g. "old-abcde.php"). I need an htaccess rule to set up a 301 redirect so that any request for a file starting with "old-" goes to its corresponding new version (e.g. "abcde.php"). To be clear, I have many files, not just one, so I can't do a literal filename match. I basically just need to strip off the "old-" from request and redirect to the version without it. I know I probably just need a simple regular expression, but I'm not good at writing them. Can anyone provide assistance?

• Visual C++, CMap object save to blob column

  - by ilansch

  I have a MFC CMap object, each object stores 160K~ entries of long data. I need to store it on Oracle SQL. we decided to save it as a blob. since we do not want to make additional table. we also thought about saving it as local file and point the SQL column to that file, but we rather just keep it as blob on the server and clear the table every couple of weeks. The table has a sequential key as ID, and 2 column of time. I need to add the blob column in order to store on every row that CMap. Can you recommend a guide to do so (read/write Map to blob or maybe a clob) ? Thanks.
