• How does apt-btrfs-snapshot work?

  - by Oli

  I read on the planet that apt-btrfs-snapshot would be available for Natty. The brief description of what it does sounds very nice: it will automatically create filesystem snapshot (of everything but /home) when apt installs/removes/upgrades. With the apt-btrfs-snapshot cli app its easy to list/remove/rollback the snapshots But before I convert my entire life to btrfs for the sole purpose of gaining a built-in backup system, can anybody tell me how btrfs's snapshots work. To my layman's brain, it sounds like this would eat a devastating amount of disk space if you're taking snapshots every time you install or upgrade something (I do this more than once a day). I assume the system is smarter than I'm allowing it but I really don't know. How do the snapshots work?

• Is there a Design Pattern for preventing dangling references?

  - by iFreilicht

  I was thinking about a design for custom handles. The thought is to prevent clients from copying around large objects. Now a regular handle class would probably suffice for that, but it doesn't solve the "dangling reference problem"; If a client has multiple handles of the same object and deletes the object via one of them, all the others would be invalid, but not know it, so the client could write or read parts of the memory he shouldn't have access to. Is there a design pattern to prevent this from happening? Two ideas: An observer-like pattern where the destructor of an object would notify all handles. "Handle handles" (does such a thing even exist?). All the handles don't really point to the object, but to another handle. When the object gets destroyed, this "master-handle" invalidates itself and therefore all that point to it.

• How do I install a DVD decryption library?

  - by rocket101

  I recently built a computer running Ubuntu 11.10. It works great, except for one thing. With some video DVDs, when I insert them into my drive, the movie player just says "An error occurred. Could not read DVD. This may be because the DVD is encrypted and a DVD decryption library is not installed." My mac plays the DVD just fine. What is a DVD decryption library, and how can I install it? Thanks! EDIT: I need LEGAL way to do this. All I want is to be able to use this computer as a HTPC!

• Is it needed to have your blog title and description in H1 and H2

  - by Saif Bechan

  I have read an article that states that it is not necessary to have your blog title and description on your website at all. Just have the titles of the posts in h1, on the index and the post page. And on the post page have your different sections started with h2. Widget headers start with h3. Title and description are most of the time in the logo image. I have looked at the source of my favorite blog, http://net.tutsplus.com, and I see they do the same. Is this recommended?

• Stopping duplicate H1 and title from dynamic content

  - by codemonkey

  I have a web site where there are lots of dynamically (database driven) created pages. These pages are basically used to show uploaded images The pages look a bit like this URL: http://www.mywebsite.com/page-id/page-title/ H1: View from the sea This is a big issue because I might have 10 other pages with the title: 'View from the sea'. I know the simple solution would be to make sure the pages are named differently but I have lots of users on the web site so it's not that simple. What do you guys think to putting the page-id with the page-title in the H1 tag? So it might read 437 - View from the sea. I need to differentiate the h1 titles. I think using the page-id would help but if anyone has a better solution that would be great! Thanks in advance

• Do you think code is self documenting?

  - by Desolate Planet

  This is a question that was put to me many years ago as a gradute in a job interview and it's kind of picked at my brain now and again and I've never really found a good answer that satisfies me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

• Down Time

  - by andyleonard

  Introduction Every now and then, everyone needs a break. How do we respond when community leaders need a break? How should we respond? It's Normal People are cyclic animals - humans are diurnal by nature. We eat at regular intervals and are most comfortable when things go according to schedule. This is the lizard brain in action. So it's perfectly normal for community volunteers and leaders to engage in cycles of activity and inactivity in the community. It is, after all, another cycle. We rely on...(read more)

• Routing in ASP.Net 4.0 Web Forms

  - by nikolaosk

  In this blog post I would like to talk about a new ASP.Net 4.0 feature, URL Routing . I know this issue has been explained from various people on the web but I will give my own example. We could implement routing since ASP.Net 3.5 SP1 but it was there primarily to support ASP.Net MVC . Even in that release you could implement rounting in web forms but it was a quite difficult thing to do. However in ASP.Net 4.0 there is an integrated support for routing. It becomes easy to map requests in your site...(read more)

• Catching multiple exceptions on the client is robust and easy

  - by Alexander Kuznetsov

  Maria Zakourdaev has just demonstrated that if our T-SQL throws multiple exceptions, ERROR_MESSAGE() in TRY..CATCH block will only expose one. When we handle errors in C#, we have a very easy access to all errors. The following procedure throws two exceptions: CREATE PROCEDURE dbo.ThrowsTwoExceptions AS BEGIN ; RAISERROR ( 'Error 1' , 16 , 1 ) ; RAISERROR ( 'Error 2' , 16 , 1 ) ; END ; GO EXEC dbo.ThrowsTwoExceptions ; Both exceptions are shown by SSMS: Msg 50000 , LEVEL 16 , State 1 , PROCEDURE...(read more)

• Has programming ruined your perception of round numbers?

  - by Jon Purdy

  Most of the world works in base 10 nowadays, but as programmers working on binary systems, we constantly find ourselves working with powers of 2. While most people consider integer multiples of powers of 10 "nice and round" and somehow aesthetically superior, I found early on in my programming adventures that multiples of powers of 2 feel much more intuitively round to me: fewer factors, of course. I'm much more likely to lay out a Web site using, say, 8- or 16-pixel margins rather than 10 or 20, and when someone remarks that 128 is an insanely arbitrary number of ounces to be in a gallon, I have to smile a little inside at how, just perhaps, the U.S. system might be superior to metric in one small way. I'm just curious: has programming ruined (read: altered) your perception of the roundness of a number?

• Need Help Unable to Mount Location

  - by Don't ASk Ubun

  I am not able to start Windows and am using a DVD copy of Ubuntu to start up. I see my 750 GB Hard Disk, but if I click it i get this error: Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. After googling for a while I think I need to do sudo apt-get install ntfsprogs but when I try that: E: Package 'ntfsprogs' has no installation candidate My problem is a lot like this thread

• How do I mount shared folders (win7 host) in Ubuntu (guest) using VMware(tools v6)

  - by V-Light

  Hello, Experts. I've successfully installed VMware tools for Ubuntu. Everything seems to work fine, but shared folders were not mounted automatically. How do I get them to work? If I run vmware-hgfsclient in terminal, I get the list of shared folders, but ls -l /mnt/hgfs is empty. Actually there's no hgfs dir in /mnt. I know I should probably use the vmware-hgfsclient tool, but I realy don't know how. P.S. I wouldn't ask if I could understand the vmware-hgfsclient help I've read. Any suggestions?

• What is the convention for the star location in reference variables?

  - by Brett Ryan

  Have been learning Objective-C and different books and examples use differing conventions for the location of the star (*) when naming reference variables. MyType* x; MyType *y; MyType*z; // this also works Personally I prefer the first option as it illustrates that x is a "pointer type of MyType". I see the first two used interchangeably, and sometimes in the same code I've seen differing uses of both. I want to know what is the most common convention It's been a very long time since I've programmed in C (15 years) so I can't remember if all variants are legal for C also or if this is Objective-C specific. I'd prefer answers which state why one is better than the other, as how I explained how I read it above.

• Using Substring() in XML FLOWR Queries

  - by Jonathan Kehayias

  Tonight I was monitoring the #sqlhelp hashtag on Twitter for a response to a question I asked when Randy Knight ( Twitter ) asked a question about using SUBSTRING in FLOWR statements with XML. #sqlhelp Is there a way to do a SQL Type "LIKE" or "SUBSTRING" in the where clause of FLWOR statement? Need to evaluate just first n chars. By the time I posted a response, Randy had figured out how to use the contains() function to solve his problem, but I am going to blog this because...(read more)

• How to install Radeon Open Source Driver?

  - by Clintonio

  I have an MSI Radeon HD 7850 card. MSI provide no Linux support, and the AMD driver gives me an Unsupported Hardware watermark that does not show up in screenshots. I uninstalled the proprietary driver and found that Unity 3D no longer works, and I really only picked Ubuntu because of the excellent shortcuts provided in the recent versions. Trying to locate the open source driver has been a pain for me. According to the documentation I have read it is pre-included in Ubuntu 12.04, yet there is no Unity 3D support. I tried using the newest drivers from AMD's website, but that also had the watermark. Does anyone know how I can get the open source driver? If not, does anyone know how to remove the watermark. I'm on the verge of going back to Windows.

• Run your cpus fast but not hot

  - by John Paul Cook

  Paul Randall recently blogged about the importance of checking to make sure you are getting every bit of speed you should from your cpus. He recommended that people use CPU-Z , a free tool I recommend and have been using for many years. Power saving features in a cpu are great for laptops. Battery life is greatly extended when a processor isn't running to the max all of the time. But this isn't necessarily a good thing for a server. As Paul and others have pointed out, the processor might not get...(read more)

• Attaining credit card data

  - by Adam

  I've read the many posts on this site that say we are not allowed to store cc numbers if we are not pci-compliant. But, I'm wondering if it is possible to send a CC number through a form to an email address? Would that be still infringing on the standards? The reason I ask is that a local business owner wants to retrieve a number through a form on his website, so he can manually enter the cc info on his end. I'm assuming the only way to properly get a credit card number is to setup a merchant account? What's the best way to get a cc number without calling the actual customer? I'm thinking email is a bad idea as well.

• Time To Consider Getting Your Oracle Certification?

  - by Paul Sorensen

  Hi Everyone,I recently read an interesting study from Global Knowledge titled: 2010 IT Skills and Salary Report which contains a lot of great information related to IT worker trends including roles, required skills, demographics, salaries and more. I had to dig a little bit, but the report indicates that certification is valued by the majority of managers and those become certified, which underscores the results of our own surveys that show how certification is valued by IT workers, their employers and their customers.Additionally, if you look a little closer you will also find average salaries for those who are Oracle certified. Their salary figures are impressive and are among the top salaries of the certifications listed.If you have ever considered becoming certified or are in the process of becoming certified, I encourage you to look at the Global Knowledge study. With an ever-increasing suite of Oracle certifications available to you, there may be something within our certification offerings that will help you increase your skills, build your career, and gain additional credibility.Thank you,QUICK LINKSGlobal Knowledge 2010 IT Skills and Salary ReportOracle Certification 2009 Salary SurveyOracle Certification web site

• How to understand Linux kernel source code for a beginner?

  - by Amit Chavan

  Hi, I am a student interested in working on Memory Management, particularly the page replacement component of the linux kernel. What are the different guides that can help me to begin understanding the kernel source? I have tried to read the book Understanding the Linux Virutal Memory Manager by Mel Gorman and Understanding the Linux Kernel by Cesati and Bovet, but they do not explain the flow of control through the code. They only end up explaining various data structures used and the work various functions perform. This makes the code more confusing. My project deals with tweaking the page replacement algorithm in a mainstream kernel and analyse its performance for a set of workloads. Is there a flavor of the linux kernel that would be easier to understand(if not the linux-2.6.xx kernel)?
