  • way to back up sql server 2005 database to just get the data and objects

    - by Caveatrob
    I'm trying to do a nightly backup of a SQL Server 2005 database to get the leanest, smallest file that includes all the table data, stored procedures, views, and functions. I'm downloading and saving this daily in case the server isn't available and I need to just get some data out. I don't care about the logs or any other parts of the DB but the data, procs, tables, and functions. What's the easiest way to get just this information backed up?

  • Should you always pass the bare minimum data needed into a function

    - by Anders Holmström
    Let's say I have a function IsAdmin that checks whether a user is an admin. Let's also say that the admin checking is done by matching user id, name and password against some sort of rule (not important). In my head there are then two possible function signatures for this: public bool IsAdmin(User user); public bool IsAdmin(int id, string name, string password); I most often go for the second type of signature, thinking that: The function signature gives the reader a lot more info The logic contained inside the function doesn't have to know about the User class It usually results in slightly less code inside the function However I sometimes question this approach, and also realize that at some point it would become unwieldy. If for example a function would map between ten different object fields into a resulting bool I would obviously send in the entire object. But apart from a stark example like that I can't see a reason to pass in the actual object. I would appreciate any arguments for either style, as well as any general observations you might offer. I program in both object oriented and functional styles, so the question should be seen as regarding any and all idioms.

  • Recovery from hell - undeleting partition overwritten by Xubuntu 12.10 installer?

    - by DaimyoKirby
    This is turning into a nightmare - following my initial recovery of my two partitions, I went to install Xubuntu 12.10 (again). At this time I had two partitions - one of ~39 GB had Zorin OS 6 installed on it, and another of ~33 GB had nothing installed, just a few files in it that I had manually backed up (moved) there. When I got to the partitioning step, I chose "Replace Zorin OS 6 with Xubuntu 12.10", along with LVM, naturally thinking that the installer wouldn't touch the second partition, since Zorin wasn't installed on it. I was dead wrong. Upon booting my newly installed Xubuntu 12.10, I found in gparted that there were only two partitions - ~255MB, which appears to have the boot stuff in it (it's flagged boot in gparted), and another of ~74 GB. Question: Is there any way to salvage my old files on the non-Zorin ext3 partition? I'm really upset I made such a dumb move (again...), and any and all help is appreciated very, very much!

  • Repair ext4 filesystem on USB drive

    - by phineas
    Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

  • recover from sudo rm -rf command

    - by user106116
    By mistake, I ended up executing "rm -rf /" command from sudo on my laptop which erased many files before it stopped. Now when I restarted my system , it gives a GRUB rescue prompt. I am having dual boot with Ubuntu 12.04 and Windows 7 I request the help for following: How do I fix the currently installed Ubuntu without overwriting/erasing the left over files (from rm -rf command)? Is using Boot-Repair safe ? Is there a way to directly go to Windows 7?

  • Is it Considered Good SQL practice to use GUID to link multiple tables to same Id field?

    - by Mallow
    I want to link several tables to a many-to-many(m2m) table. One table would be called location and this table would always be on one side of the m2m table. But I will have a list of several tables for example: Cards Photographs Illustrations Vectors Would using GUID's between these tables to link it to a single column in another table be considered 'Good Practice'? Will Mysql let me to have it automatically cascade updates and delete? If so, would multiple cascades lead to an issues? UPDATE I've read that GUID (a hex number) Generally takes up more space in a database and slows queries down. However I could still generate 'unique' ids by just having the table initial's as part of the id so that the table card's id would be c0001, and then Illustrations be I001. Regardless of this change, the questions still stands.

  • Accidentally hit shortcut and lost text in web browser. Can it be disabled?

    - by uniomni
    I have noticed that I occasionally hit some shortcut while typing that either kills the browser or otherwise causes me to lose e.g. a post I am writing. This typically happens if I type while on a bumpy road or something like that. It also just happened to my eight year old daughter ;-( I think the shortcut in question is CTRL-w which (at least in Firefox) closes the current tab and consequently whatever content is being written. I would like to know if anyone has noticed this and if someone has a solution e.g. a way to disable "dangerous" shortcuts if at all possible. Many thanks Ole (uniomni)

  • Data base preference for network based C# windows application [on hold]

    - by Sinoop Joy
    I'm planning to develop a C# widows based application for an academy. The academy will have different instances of application running in different machines. The database should have shared access. All the application instances can do update, delete or insert. I've not done any network based application. Anybody can give any useful link to where to start with ? Which database would give max performance with all required features i said for this scenario ?

  • Searching for entity awareness in 3D space algorithm and data structure

    - by Khanser
    I'm trying to do some huge AI system just for the fun and I've come to this problem. How can I let the AI entities know about each other without getting the CPU to perform redundant and costly work? Every entity has a spatial awareness zone and it has to know what's inside when it has to decide what to do. First thoughts, for every entity test if the other entities are inside the first's reach. Ok, so it was the first try and yep, that is redundant and costly. We are working with real time AI over 10000+ entities so this is not a solution. Second try, calculate some grid over the awareness zone of every entity and test whether in this zones are entities (we are working with 3D entities with float x,y,z location coordinates) testing every point in the grid with the indexed-by-coordinate entities. Well, I don't like this because is also costly, but not as the first one. Third, create some multi linked lists over the x's and y's indexed positions of the entities so when we search for an interval between x,y and z,w positions (this interval defines the square over the spatial awareness zone) over the multi linked list, we won't have 'voids'. This has the problem of finding the nearest proximity value if there isn't one at the position where we start the search. I'm not convinced with any of the ideas so I'm searching for some enlightening. Do you people have any better ideas?

  • Places to store basic data

    - by Ella
    I am using PHP. I'm building a fully modular CMS, which is destined for the public. Some people might view this as a framework, but I intend to write a set of extensions for it, extensions that will make it a CMS :P Because it's completely modular I have a problem figuring out how to load extensions. Practically I need to get the list of active extensions, so I can load them inside my base class. I load them by reading some file headers, which contain a "dependency" field. That field decides the order in which I have to instantiate the objects. The problem is that when the CMS starts I have no database interface, because that's an extension too, so I can't store the active extensions list in the database :) You might ask how are extensions activated in the first place. Well - in the administration interface, which is an extension as well (obviously on first install of the CMS there will be some extensions active by default). Could writing that list inside a text file be a solution? The problem is that a lot of hosts are not very nice with scripts when they write files. And since this CMS is public I might have a problem here?

  • Octrees as data structure

    - by Christian Frantz
    In my cube world, I want to use octrees to represent my chunks of 20x20x20 cubes for frustum and occlusion culling. I understand how octrees work, I just dont know if I'm going about this the right way. My base octree class is taken from here: http://www.xnawiki.com/index.php/Octree What I'm wondering is how to apply occlusion culling using this class. Does it make sense to have one octree for each cube chunk? Or should I make the octree bigger? Since I'm using cubes, each cube should fit into a node without overlap so that won't be an issue

  • audio and video data in RTP

    - by Banana
    Suppose a user wants to transmit both audio and video to another user, whose formats are AMR for audio and H.264 for video. Does the user have to transmit audio and video packets always separately? Meaning that it is not possible to mix audio and video within the same RTP packed, is that correct? If this is true I guess the RTP protocol will need to know the SSRC of both audio and video to be able to check the sync of the two streams.

  • When to use an Array vs When to use a Vector, when dealing with GameObjects?

    - by user32465
    I understand that from other answers, Arrays and Vectors are the best choices. Many on SE claim that Linked Lists and Maps are bad for video game programming. I understand that for the most part, I can use Arrays. However, I don't really understand exactly when to use Vectors over Arrays. Why even use Vectors? Wouldn't it be best if I simply always used an Array, that way I know how much memory my game needs? Specifically my game would only ever load a single "Map" area of tiles, such as Map[100][100], so I could very easily have an array of GameObjectContainer GameObjects[100][100], which would reserve an entire map's worth of possible gameobjects, correct? So why use a Vector instead? Memory is quite large on modern hardware.

  • Inserting Data into a Microsoft SQL 2008 Database in ASP.NET 3.5

    In the previous article Creating an ASP.NET Dynamic Web Page using a MS SQL Server 2 8 Database GridView Display you learned how to create a dynamic web page that can let the user edit and delete database records directly using a web browser. It was demonstrated with a home renovation project where team leaders can update and delete project tasks online. However it does not include features that let users add or insert new records directly into the database using a web browser. This feature will be covered in this tutorial....

  • Traverse tree with results. Maybe type in Java?

    - by Angelo.Hannes
    I need to check a tree's node state. It can either be OK or NOT_OK. But that state is dependent on its children. So for a node to be OK, every of its children needs to be OK. If one or more of its children is NOT_OK the whole node is NOT_OK. To determine the state of a node I need to aggregate some properties of the node. So I thought of two possible implementations. And they are more or less covered in this question: Why is Option/Maybe considered a good idea and checked exceptions are not? Exception I could pass the properties up the recursion path, and throw an exception if something went wrong. Maybe I implement an Maybe type and let it either hold an error or the aggregated properties. Maybe it is more an Either. I tend towards the last option. And I'm thinking of an enum with two objects. Where I can additionally set those aggregated properties. Am I on the right track? I'm not familiar with the new JDK8 functional stuff. But I'm stuck on JDK7 anyway, so please focus on JDK7.

  • Requirement, architecture data capture tool

    - by Deno
    Are there any tools available for the following use case: I am planning to write a complex application and now I just know about the basic functional requirments. I am refining the functionality with more and more details. I am also writing down how to implement this in software architecture perspective. I am in a situation where there are multiple ways implement a certain functionality and based on the selected approach, other parts of the program will also change. At this moment, I don't want to decide on the approach to use, I just want to list down all the options, present to a wider audience and get it finalized. Are there any standard software tools to do this? I know I can use MS excel or some mind mapper tools, but just thinking of some standard tools (not just for programmers, but for managers and other) availability Thanks, Den
