• Kernel panic error

  - by cioby23

  We have a dedicated server with software RAID1 and one of the disk failed recently. The disk was replaced but after rebuilding the array and rebooting the server freezes with a Kernel Panic message No filesystem could mount root, tried: reiserfs ext3 ext2 cramfs msdos vfat iso9660 romfs fuseblk xfs Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(9,1) The filesystem on both disks is ext4. It seems the kernel can't load ext4 support. Is there any way to add ext4 support or do I need to recompile a new kernel again ? Interesting point that before disk replacement all was fine. The kernel is a stock kernel bzImage-2.6.34.6-xxxx-grs-ipv6-64 from our provider OVH Kind regards,

• IT Optimization Plan Pays Off For UK Retailer

  - by [email protected]

  I caught this article in ComputerworldUK yesterday. The headline talks about UK-based supermarket chain Morrisons is increasing their IT spend...OK, sounds good. Even nicer that Oracle is a big part of that. But what caught my eye were three things: 1) Morrison's truly has a long term strategy for IT. In this case, modernizing and optimizing how they use IT for business advantage. 2) Even in a tough economic climate, Morrison's views IT investments as contributing to and improving the bottom line. Specifically, "The investment in IT contributed to a 21 percent increase in Morrison's underlying profit.." 3) The phased, 3-year "Optimization Plan" took a holistic approach to their business--from CRM and Supply Chain systems to the underlying application infrastructure. On the infrastructure front, adopting a more flexible Service-Oriented Architecture enabled them to be more agile and adapt their business and Identity Management helped with sometimes mundane (but costly) issues like lost passwords and being able to document who has access to what. Things don't always turn out so rosy. And I know it was a long and difficult process...but it's nice to see a happy ending every once in a while.

• Silverlight Version 4 latest build for Win7 64bit and WinXP 32bit

  - by Paul

  I have a requirement where a few people need the latest version of Silverlight 4 installed. I know the latest version is 5.xx... but apparently with some new software we're having installed we have to use version 4 After a bit of googling i can see that the latest version is... Build 4.1.10329.0 Released May 8, 2012 We have a mix of Win7 64-bit machines and WinXP 32-bit machines. Q: Is there a different version for each OS or the same one fits all. (This seems strangely hard to decipher by googling) Q: Does anyone know where i can download the latest version 4? Microsoft do not seem to offer it anymore unless i'm just not finding it. Q: Is there a separate browser version of it or will installing it also handle any browser needs (our new software will be browser based) Any pointers much appreciated. Paul

• Tmux causes Emacs glitch

  - by killy9999

  Recently I started using Tmux, but I noticed that it causes a strange Emacs glitch. When I open source code for elisp or haskell, the comments aren't highlighted. Only the comment sign is (; in case of elisp, -- in case of haskell). The rest of the commented line is in normal colour. When I run Emacs outside of Tmux everything works as expected - the whole commented line is highlighted in a colour denoting a comment. Any ideas why this is happening? SOLUTION: Based on Stefan's comment I added this to my .emacs file: (custom-set-variables (custom-set-faces '(font-lock-comment-face ((((class color) (min-colors 8) (background dark)) (:foreground "red")))))) Now the comments are displayed in red, just like comment delimiters.

• Dependency injection: what belongs in the constructor?

  - by Adam Backstrom

  I'm evaluating my current PHP practices in an effort to write more testable code. Generally speaking, I'm fishing for opinions on what types of actions belong in the constructor. Should I limit things to dependency injection? If I do have some data to populate, should that happen via a factory rather than as constructor arguments? (Here, I'm thinking about my User class that takes a user ID and populates user data from the database during construction, which obviously needs to change in some way.) I've heard it said that "initialization" methods are bad, but I'm sure that depends on what exactly is being done during initialization. At the risk of getting too specific, I'll also piggyback a more detailed example onto my question. For a previous project, I built a FormField class (which handled field value setting, validation, and output as HTML) and a Model class to contain these fields and do a bit of magic to ease working with fields. FormField had some prebuilt subclasses, e.g. FormText (<input type="text">) and FormSelect (<select>). Model would be subclassed so that a specific implementation (say, a Widget) had its own fields, such as a name and date of manufacture: class Widget extends Model { public function __construct( $data = null ) { $this->name = new FormField('length=20&label=Name:'); $this->manufactured = new FormDate; parent::__construct( $data ); // set above fields using incoming array } } Now, this does violate some rules that I have read, such as "avoid new in the constructor," but to my eyes this does not seem untestable. These are properties of the object, not some black box data generator reading from an external source. Unit tests would progressively build up to any test of Widget-specific functionality, so I could be confident that the underlying FormFields were working correctly during the Widget test. In theory I could provide the Model with a FieldFactory() which could supply custom field objects, but I don't believe I would gain anything from this approach. Is this a poor assumption?

• SSO between multiple Flex applications

  - by KarthiPk

  We have three applications developed in Flex and all these use BlazeDS. These applications have their own authentication implementations (Database). Also they will be deployed in tomcat. Deploying all these applications in the same tomcat instance is acceptable for us. We want to bring the authentication credentials of all these applications into a single place and also provide SSO feature between these applications. We also want the authentication module to be configurable. Something like the system administrator can decide if the authentication should be done against a database or LDAP. Say, if the user successfully logs into app1, and when he access app2 in the same browser he should be automatically logged in. Same goes for logout as well. We have been exploring OpenAM, jGuard and JOSSO. I'm not sure if these require lot of customization to work with Flex. I would like to know how people are implementing SSO for Flex applications. Is there a common and simple SSO solution available for Flex based applications ?

• More Tables or More Databases?

  - by BuckWoody

  I got an e-mail from someone that has an interesting situation. He has 15,000 customers, and he asks if he should have a database for their data per customer. Without a LOT more data it’s impossible to say, of course, but there are some general concepts to keep in mind. Whenever you’re segmenting data, it’s all about boundary choices. You have not only boundaries around how big the data will get, but things like how many objects (tables, stored procedures and so on) that will be involved, if there are any cross-sections of data (do they share location or product information) and – very important – what are the security requirements? From the answer to these types of questions, you now have the choice of making multiple tables in a single database, or using multiple databases. A database carries some overhead – it needs a certain amount of memory for locking and so on. But it has a very clean boundary – everything from objects to security can be kept apart. Having multiple users in the same database is possible as well, using things like a Schema. But keeping 15,000 schemas can be challenging as well. My recommendation in complex situations like this is similar to a post on decisions that I did earlier – I lay out the choices on a spreadsheet in rows, and then my requirements at the top in the columns. I  give each choice a number based on how well it meets each requirement. At the end, the highest number wins. And many times it’s a mix – perhaps this person could segment customers into larger regions or districts or products, in a database. Within that database might be multiple schemas for the customers. Of course, he needs to query across all customers, that becomes another requirement. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• How to setup certificate authentication for MS SQL server 2008 R2 ?

  - by Stephane

  Hello, I have to connect an (ADO) application running on a standalone Windows 2003 R2 server to a SQL 2008 R2 database that is a member of the domain. I have setup an SQL authentication account for this and hard-coded the password into the connection string but I wonder if it wouldn't be possible to use certificate-based authentication for this instead. I haven't been able to find any documentation regarding this apparently new functionality of SQL 2008 R2 anywhere. Could someone kindly point me at some good documentation ? Or at least a description of the functionality and whether it could be used in my case or not ? Thank you in advance

• MySQL Database synchronizing with local and remote with c#

  - by Neo

  I've posted this here as its more of a mysql questions than c#, I have written some software that runs a local instance of mysql when it first starts, now once mysql is up I would like to synchronize the data between the remote database table and the local database table that the software runs (it shouldn't sync any other databases / tables as there are a lot). I have replication setup to synchronize the entire database to another server which works unless the server goes down then it never comes back up, so based on that I don't think replication will work as when the software is closed it also closes MySQL. So what would be the best method of synchronizing the remote and local databases?

• PHP ORM style of querying

  - by Petah

  Ok so I have made an ORM library for PHP. It uses syntax like so: *(assume that $business_locations is an array)* Business::type(Business:TYPE_AUTOMOTIVE)-> size(Business::SIZE_SMALL)-> left_join(BusinessOwner::table(), BusinessOwner::business_id(), SQL::OP_EQUALS, Business::id())-> left_join(Owner::table(), SQL::OP_EQUALS, Owner::id(), BusinessOwner::owner_id())-> where(Business::location_id(), SQL::in($business_locations))-> group_by(Business::id())-> select(SQL::count(BusinessOwner::id()); Which can also be represented as: $query = new Business(); $query->set_type(Business:TYPE_AUTOMOTIVE); $query->set_size(Business::SIZE_SMALL); $query->left_join(BusinessOwner::table(), BusinessOwner::business_id(), SQL::OP_EQUALS, $query->id()); $query->left_join(Owner::table(), SQL::OP_EQUALS, Owner::id(), BusinessOwner::owner_id()); $query->where(Business::location_id(), SQL::in($business_locations)); $query->group_by(Business::id()); $query->select(SQL::count(BusinessOwner::id()); This would produce a query like: SELECT COUNT(`business_owners`.`id`) FROM `businesses` LEFT JOIN `business_owners` ON `business_owners`.`business_id` = `businesses`.`id` LEFT JOIN `owners` ON `owners`.`id` = `business_owners`.`owner_id` WHERE `businesses`.`type` = 'automotive' AND `businesses`.`size` = 'small' AND `businesses`.`location_id` IN ( 1, 2, 3, 4 ) GROUP BY `businesses`.`id` Please keep in mind that the syntax might not be prefectly correct (I only wrote this off the top of my head) Any way, what do you think of this style of querying? Is the first method or second better/clearer/cleaner/etc? What would you do to improve it?

• SQL SERVER – A Puzzle Part 2 – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value

  - by pinaldave

  Before continuing this blog post – please read the first part of the SEQUENCE Puzzle here A Puzzle – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value. Where we played a simple guessing game about predicting next value. The answers the of puzzle is shared on the blog posts as a comment. Now here is the next puzzle based on yesterday’s puzzle. First execute the script which I have written here. The only difference between yesterday’s script is that I have removed the MINVALUE as 1 from the syntax. Now guess what will be the next value as requested in the query. USE TempDB GO -- Create sequence CREATE SEQUENCE dbo.SequenceID AS BIGINT START WITH 3 INCREMENT BY 1 MAXVALUE 5 CYCLE NO CACHE; GO -- Following will return 3 SELECT next value FOR dbo.SequenceID; -- Following will return 4 SELECT next value FOR dbo.SequenceID; -- Following will return 5 SELECT next value FOR dbo.SequenceID; -- Following will return which number SELECT next value FOR dbo.SequenceID; -- Clean up DROP SEQUENCE dbo.SequenceID; GO Above script gave me following resultset. 3 is the starting value and 5 is the maximum value. Once Sequence reaches to maximum value what happens? and WHY? I (kindly) suggest you try to attempt to answer this question without running this code in SQL Server 2012. I am very confident that irrespective of SQL Server version you are running you will have great learning. I will follow up of the answer in comments below. Recently my friend Vinod Kumar wrote excellent blog post on SQL Server 2012: Using SEQUENCE, you can head over there for learning sequence in details.

• How to make a btrfs snapshot?

  - by MountainX

  My /home partition consists of an entire physical disk. It is formatted as btrfs. I want to snapshot it. I'm confused regarding subvolume naming, in particular. I am aware that there are similar questions, but each similar question seems to be asking something different from what I'm asking (and they are older, which means probably outdated, given the rapid development of btrfs). For example, the answer to this question is apparently not the answer to my question because my /home partition is a separate volume and the man page for btrfs shows a different command for creating snapshots now. another similar problem, no solid solution. someone else as confused as me on the naming issues My question: Starting simple: is this the correct command to take a simple snapshot of my home partition? btrfs subvolume snapshot /home/@home /home/@home_snapshot_20120421 I got really brave and tested it and it does not work. The error is error accessing /home/@home. As shown below, @home is listed. I'm obviously confused on subvolume names. Do I need to use them in creating snapshots? Some examples show taking snapshots of home using /home as the source parameter, but based on examples of root volumes, it seems to me that I need to use /home/@home. Would this command work? And if not, why? btrfs subvolume snapshot /home /home/@home_snapshot_20120421 Is the @ just a naming convention? Is it meaningful at all? Here's some output that may be relevant: btrfs subvolume list /home ID 256 top level 5 path @home I'm not sure what that means, exactly. When I try btrfs device scan it gives an error (e.g. unable to scan the device /dev/sda1). My file system doesn't have any errors. Everything is fine.

• A Consol Application or Windows Application in VS 2010 for Sharepoint 2010 : A common Error

  - by Gino Abraham

  I have seen many Sharepoint Newbies cracking their head to create a Console/Windows  application in VS2010 and make it talk to Sharepoint 2010 Server. I had the same problem when i started with Sharepoint in the begining. It is important for you to acknowledge that SharePoint 2010 is based on .NET Framework version 3.5 and not version 4.0. In VS 2010 when you create a Console/Windows application, Make Sure you select .Net Framework 3.5 in the New Project Dialog Window.If you have missed while creating new Project Go to the Application tab of project properties and verify that .NET Framework Version 3.5 is select as the Target Framework. Now that you have selected the correct framework, will it work? Nope if the application is configured as x86 one it will not work. Sharepoint is a 64 Bit application and when you create a windows application to talk to Sharepoint it should also be a 64 Bit one. Go to Configuration Manager, Select x64. If x64 is not available select <New…> and in the New Solution Platform dialog box select x64 as the new platform copying settings from x86 and checking the Create new project platforms check box. This is not applicable if you are making a console application to talk to sharepoint with Client Object Model.

• Why is mcrypt not included in most Linux distributions?

  - by Daniel Lopez

  libmcrypt is a powerful encryption library that is very popular with PHP-based applications. However, most Linux distributions do not include it. This causes problems for many users that need to download and compile it separately. I am guessing that the reason it is not shipped is related to encryption or patent issues. However, the source code for library itself is hosted and available on sourceforge.net I have been searching unsuccessfully for a document of authoritative post that explains the exact issues why this extension is not bundled with mainstream distributions. Can anyone provide a pointer to such material or provide an explanation?

• Restoring GRUB2 on Software RAID 0 after Windows 7 wiped it using LiveCD

  - by unknownthreat

  I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did. Right now, my partition on my Software RAID 0 looks like this: nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". Here's the text from the console: ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, ** (http://grub.enbug.org/Grub2LiveCdInstallGuide) **try to look around, and try: ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda. However, ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.

• How can I use `SetEnvIf` to clear an Apache2 environment variable?

  - by Jamie

  In my apache2 configuration I've got these lines: SetEnv log_everything # Create the environment variables based on access requests SetEnvIf Request_URI "^/orders/.*$" download_access !log_everything SetEnvIf Request_URI "^/download/.*$" download_access !log_everything SetEnvIf Request_URI "^/wg/.*$" wg_1x1_access !log_everything # Log the accesses using the generated environment variable as conditionals.

How can I configure this so that "wg" and "download/orders" requests won't be duplicated in access.log?

• Is micro-optimisation important when coding?

  - by BozKay

  I recently asked a question on stackoverflow.com to find out why isset() was faster than strlen() in php. This raised questions around the importance of readable code and whether performance improvements of micro-seconds in code were worth even considering. My father is a retired programmer, I showed him the responses and he was absolutely certain that if a coder does not consider performance in their code even at the micro level, they are not good programmers. I'm not so sure - perhaps the increase in computing power means we no longer have to consider these kind of micro-performance improvements? Perhaps this kind of considering is up to the people who write the actual language code? (of php in the above case). The environmental factors could be important - the internet consumes 10% of the worlds energy, I wonder how wasteful a few micro-seconds of code is when replicated trillions of times on millions of websites? I'd like to know answers preferably based on facts about programming. Is micro-optimisation important when coding? EDIT : My personal summary of 25 answers, thanks to all. Sometimes we need to really worry about micro-optimisations, but only in very rare circumstances. Reliability and readability are far more important in the majority of cases. However, considering micro-optimisation from time to time doesn't hurt. A basic understanding can help us not to make obvious bad choices when coding such as if (expensiveFunction() && counter < X) Should be if (counter < X && expensiveFunction()) (example from @zidarsk8) This could be an inexpensive function and therefore changing the code would be micro-optimisation. But, with a basic understanding, you would not have to because you would write it correctly in the first place.

• Starting an HTML canvas game with no graphics skills

  - by Jacob

  I want to do some hobby game development, but I have some unfortunate handicaps that have me stuck in indecision; I have no artistic talent, and I also have no experience with 3D graphics. But this is just a hobby project that might not go anywhere, so I want to develop the stuff I care about; if the game shows good potential, my graphic "stubs" can be replaced with something more sophisticated. I do, however, want my graphics engine to render something approximate to the end goal. The game is tile-based, with each tile being a square. Each tile also has an elevation. My target platform (subject to modification) is JavaScript rendering to the HTML 5 canvas, either with a 2D or WebGL context. My question to those of you with game development experience is whether it's easier to develop an isometric game using a 2D graphics engine and sprites or a 3D game using rudimentary 3D primitives and basic textures?
