• RAID 10: SPAN 2 vs SPAN 4

  - by LaDante Riley

  I am currently configuring RAID 10 (first time doing RAID ever) for a server at work. In the Configuration Utility. I am given the option of either span 2 or span 4. Having never done this before, I was curious if someone could tell me the pros and cons of for each span? Thanks The server is a Poweredge r620 with a PERC H710 mini (Security Capable) RAID controller. I have 8 600GB hard drives. I am creating this server as a network storage drive. I have SQL server historian database whose 1TB storage filled up and after 5 years of logging data.

• How to use SQLErrorCodeSQLExceptionTranslator and DAO class with @Repository in Spring?

  - by GuidoMB

  I'm using Spring 3.0.2 and I have a class called MovieDAO that uses JDBC to handle the db. I have set the @Repository annotations and I want to convert the SQLException to the Spring's DataAccessException I have the following example: @Repository public class JDBCCommentDAO implements CommentDAO { static JDBCCommentDAO instance; ConnectionManager connectionManager; private JDBCCommentDAO() { connectionManager = new ConnectionManager("org.postgresql.Driver", "postgres", "postgres"); } static public synchronized JDBCCommentDAO getInstance() { if (instance == null) instance = new JDBCCommentDAO(); return instance; } @Override public Collection<Comment> getComments(User user) throws DAOException { Collection<Comment> comments = new ArrayList<Comment>(); try { String query = "SELECT * FROM Comments WHERE Comments.userId = ?"; Connection conn = connectionManager.getConnection(); PreparedStatement stmt = conn.prepareStatement(query); stmt = conn.prepareStatement(query); stmt.setInt(1, user.getId()); ResultSet result = stmt.executeQuery(); while (result.next()) { Movie movie = JDBCMovieDAO.getInstance().getLightMovie(result.getInt("movie")); comments.add(new Comment(result.getString("text"), result.getInt("score"), user, result.getDate("date"), movie)); } connectionManager.closeConnection(conn); } catch (SQLException e) { e.printStackTrace(); //CONVERT TO DATAACCESSEXCEPTION } return comments; } } I Don't know how to get the Translator and I don't want to extends any Spring class, because that is why I'm using the @Repository annotation

• Linux stretch cluster: MD replication, DRBD or Veritas?

  - by PieterB

  For the moment there's a lot of choices for setting up a Linux cluster. For cluster manager: you can use Red Hat Cluster manager, Pacemaker or Veritas Cluster Server. The first one has the most momentum, the second one comes by default with RH subscriptions and the last one is very expensive and has a very good reputation ;-) For storage: - You can replicate LUN's using software raid / md device - You can use the network using DRBD replication, which offers a bit more flexibility - You can use Veritas Storage Foundation technology to talk to your SANs replication technology. Anyone has any recommandations or experience with these technologies?

• Should frontend and backend handled by different controllers?

  - by DR

  In my previous learning projects I always used a single controller, but know I wonder if that is good practice or even always possible. In all RESTful Rails tutorials the controllers have a show, an edit and an index view. If an authorized user is logged on, the edit view becomes available and the index view shows additional data manipulation controls, like a delete button or a link to the edit view. Now I have a Rails application which falls exactly into this pattern, but the index view is not reusable: The normal user sees a flashy index page with lots of pictures, complex layout, no Javascript requirement, ... The Admin user index has a completly different minimalistic design, jQuery table and lots of additional data, ... Now I'm not sure how to handle this case. I can think of the following: Single controller, single view: The view is split into two large blocks/partials using an if statement. Single controller, two views: index and index_admin. Two different controllers: BookController and BookAdminController None of this solutions seems perfect, but for now I'm inclined to use the 3rd option. What's the preferred way to do this?

• Parameter based bindings in ninject 2.0

  - by Przemaas

  I want to use conditional binding in ninject, based on passed parameters. I have something like below: public class Subject { } public interface ITarget { } public class Target1 : ITarget { } public class Target2 : ITarget { } And now I need to instantiate ITarget interface: public void MethodName(IKernel kernel) { ITarget target1 = kernel.Get<ITarget>(new Parameter("name", new Subject(), true)); // Should be instance of Target1 ITarget target2 = kernel.Get<ITarget>(); // Should be instance of Target2 } I have problems to define proper bindings. I tried the following: kernel.Bind<ITarget>().To<Target1>().When(Predicate); kernel.Bind<ITarget>().To<Target2>(); private bool Predicate(IRequest request) { IParameter parameter = request.Parameters.Count == 0 ? null : request.Parameters[0]; if (parameter == null) { return false; } object parameterValue = parameter.GetValue( /*what to put here?*/); return parameterValue != null && parameterValue.GetType().IsAssignableFrom(typeof(Subject)); } but I don't know how to get value of passed parameter. I need to pass IContext instance to GetValue method, but don't know how to get valid instance of IContext. Or maybe there is better way to accomplish my task? Regards

• Is it possible to accept a button tag to be in some range iphone sdk

  - by neha

  Hi all, In my application I'm doing dynamic resizing of cells and label in it depending upon the text in it. I'm adding button to cells in uitableview. I'm taking the label instance and button instance in a new label and button variable respectively and setting their frames to arrange them properly after resizing. if(cel==nil) { //some code original_label=[[UILabel alloc]init]; original_label.tag=111; //SOME MORE CODE GOES HERE original_button=[[UIButton alloc]init]; original_button.tag=222; //SOME MORE CODE GOES HERE } new_label=(UILabel *) [cell viewWithTag:111]; //This' how I'm taking the label instance on cell and below button instance on cell in new variables new_button = (UIButton * ) [cell viewWithTag:222]; Earlier I kept the tags of all the buttons on cells same, so it was easier to get button instances on cells properly and were being arranged properly. But now I want to recognize these buttons separately as I'm adding some functionality on button_click. I'm giving the buttons that are added to the cells incremental tags[1,2,3...9 and so on]. Now, how can I take these button tags in some range like[suppose 1-9]? Can anybody help? Thanks in advance.

• Demangling typeclass functions in GHC profiler output

  - by Paul Kuliniewicz

  When profiling a Haskell program written in GHC, the names of typeclass functions are mangled in the .prof file to distinguish one instance's implementations of them from another. How can I demangle these names to find out which type's instance it is? For example, suppose I have the following program, where types Fast and Slow both implement Show: import Data.List (foldl') sum' = foldl' (+) 0 data Fast = Fast instance Show Fast where show _ = show $ sum' [1 .. 10] data Slow = Slow instance Show Slow where show _ = show $ sum' [1 .. 100000000] main = putStrLn (show Fast ++ show Slow) I compile with -prof -auto-all -caf-all and run with +RTS -p. In the .prof file that gets generated, I see that the top cost centers are: COST CENTRE MODULE %time %alloc show_an9 Main 71.0 83.3 sum' Main 29.0 16.7 And in the tree, I likewise see (omitting irrelevant lines): individual inherited COST CENTRE MODULE no. entries %time %alloc %time %alloc main Main 232 1 0.0 0.0 100.0 100.0 show_an9 Main 235 1 71.0 83.3 100.0 100.0 sum' Main 236 0 29.0 16.7 29.0 16.7 show_anx Main 233 1 0.0 0.0 0.0 0.0 How do I figure out that show_an9 is Slow's implementation of show and not Fast's?

• Ruby on Rails: How to use a local variable in a collection_select

  - by mmacaulay

  I have a partial view which I'm passing a local variable into: <%= render :partial => "products/product_row", :locals => { :product => product } %> These are rows in a table, and I want to have a <select> in each row for product categories: <%= collection_select(:product, :category_id, @current_user.categories, :id, :name, options = {:prompt => "-- Select a category --"}, html_options = { :id => "", :class => "product_category" }) %> (Note: the id = "" is there because collection_select tries to give all these select elements the same id.) The problem is that I want to have product.category be selected by default and this doesn't work unless I have an instance variable @product. I can't do this in the controller because this is a collection of products. One way I was able to get around this was to have this line just before the collection_select: <% @product = product %> But this seems very hacky and would be a problem if I ever wanted to have an actual instance variable @product in the controller. I guess one workaround would be to name this instance variable something more specific like @product_select_tmp in hopes of not interfering with anything that might be declared in the controller. This still seems very hacky though, and I'd prefer a cleaner solution. Surely there must be a way to have collection_select use a local variable instead of an instance variable. Note that I've tried a few different ways of calling collection_select with no success: <%= collection_select(product, ... <%= collection_select('product', ... etc. Any help greatly appreciated!

• Using Reflection.Emit to emit a "using (x) { ... }" block?

  - by Lasse V. Karlsen

  I'm trying to use Reflection.Emit in C# to emit a using (x) { ... } block. At the point I am in code, I need to take the current top of the stack, which is an object that implements IDisposable, store this away in a local variable, implement a using block on that variable, and then inside it add some more code (I can deal with that last part.) Here's a sample C# piece of code I tried to compile and look at in Reflector: public void Test() { TestDisposable disposable = new TestDisposable(); using (disposable) { throw new Exception("Test"); } } This looks like this in Reflector: .method public hidebysig instance void Test() cil managed { .maxstack 2 .locals init ( [0] class LVK.Reflection.Tests.UsingConstructTests/TestDisposable disposable, [1] class LVK.Reflection.Tests.UsingConstructTests/TestDisposable CS$3$0000, [2] bool CS$4$0001) L_0000: nop L_0001: newobj instance void LVK.Reflection.Tests.UsingConstructTests/TestDisposable::.ctor() L_0006: stloc.0 L_0007: ldloc.0 L_0008: stloc.1 L_0009: nop L_000a: ldstr "Test" L_000f: newobj instance void [mscorlib]System.Exception::.ctor(string) L_0014: throw L_0015: ldloc.1 L_0016: ldnull L_0017: ceq L_0019: stloc.2 L_001a: ldloc.2 L_001b: brtrue.s L_0024 L_001d: ldloc.1 L_001e: callvirt instance void [mscorlib]System.IDisposable::Dispose() L_0023: nop L_0024: endfinally .try L_0009 to L_0015 finally handler L_0015 to L_0025 } I have no idea how to deal with that ".try ..." part at the end there when using Reflection.Emit. Can someone point me in the right direction?

• Real-time offline folder-to-folder backup application needed (Windows)

  - by niktech

  I recently started using Intel Matrix Storage RAID solution that allowed me to use my 5 1TB drives for two RAID volumes. First one a 1TB RAID 0 striped across all 5 drives and second one a RAID 5 across the rest of the free space on all drives (around 2.85TB usable space). The RAID 0 I use for OS, applications and games while the RAID 5 I use as a more-permanent type storage (photos, etc). Now I do realize that running the OS and applications on RAID 0 across 5 drives is very dangerous, which is what brings up the following question. Is there a reliable freeware realtime backup application that can backup a set of folders from one drive to another drive (no online backups needed)? I've already tried a few (Mozy, Yadis, Comodo Backup, GFI Backup, Idoo, Crash Plan) but none meet my requirements: Low CPU and RAM usage. Realtime Backups - as soon as a file is modified in the source folder, it is added to the backup queue which will be processed with the lowest priority when the CPU is idle. This backup queue should persist in cases of computer restarts (ie: the source and destination folders should always have the same set of files, except for the ones waiting in the backup queue). Incremental Backups - if only 10 bytes changed in a 1GB file, the app should only copy those 10 new bytes. Ability to back up locked and opened files (some apps, like Yadis, can't back up critical files like browser favorites). Ability to run as a service (no need for any user to log-in to have the app started). Optional requirements: Compression of the destination into a well-known format (RAR, Zip) that can be directly read without the use of the application. Preset source folders (such as Browser Favorites, Game Saves, Application Settings, etc). The idea is to use RAID 0 array as "semi-persistent RAM-like" storage which in case of a failure can be quickly rebuilt by reinstalling the OS, apps and games and copying over the settings, saves, favorites from the RAID 5. I'm also thinking of taking this RAID 0 as RAM idea to the extreme with SSDs (as soon as we get some nice 6Gb/s SATA III SSDs out there), where a couple of SSDs chained in RAID 0 will work as yet another semi-persistent cache layer sitting between the RAM and the HD. I'm just hoping there already exists an application that satisfies these requirements... otherwise I'll have to write one myself, which I would prefer not to do.

• smartGWT: retrieve data from server to populate a listGrid

  - by Gabriele

  I'm searching a way to populate a ListGrid with an XML response from a server. This is an example of my server response: <?xml version="1.0" encoding="UTF-8"?> <tbody id="tbody"> <tr> <word>The</word> <frequence>12</frequence> </tr> <tr> <word>best</word> <frequence>3</frequence> </tr> ... And this is how I can populate the ListGrid using a file (item.xml) where I have saved the xml result: public class Frequenze extends DataSource { private static Frequenze instance = null; public static Frequenze getInstance() { if (instance == null) { instance = new Frequenze("frequence"); } return instance; } public Frequenze(String id) { setID(id); setRecordXPath("//tr"); DataSourceTextField wordField = new DataSourceTextField("word", "Word"); wordField.setRequired(true); DataSourceIntegerField frequenceField = new DataSourceIntegerField("frequence", "Frequence"); frequenceField.setRequired(true); setFields(wordField, frequenceField); setDataURL("ds/item.xml"); setClientOnly(true); } } Now I want not to use the file, but I'm searching a way to retrieve the data directly from the server. Anyone know how I get this?

• "Session is Closed!" - NHibernate

  - by Alexis Abril

  This is in a web application environment: An initial request is able to successfully complete, however any additional requests return a "Session is Closed" response from the NHibernate framework. I'm using a HttpModule approach with the following code: public class MyHttpModule : IHttpModule { public void Init(HttpApplication context) { context.EndRequest += ApplicationEndRequest; context.BeginRequest += ApplicationBeginRequest; } public void ApplicationBeginRequest(object sender, EventArgs e) { CurrentSessionContext.Bind(SessionFactory.Instance.OpenSession()); } public void ApplicationEndRequest(object sender, EventArgs e) { ISession currentSession = CurrentSessionContext.Unbind( SessionFactory.Instance); currentSession.Dispose(); } public void Dispose() { } } SessionFactory.Instance is my singleton implementation, using FluentNHibernate to return an ISessionFactory object. In my repository class, I attempt to use the following syntax: public class MyObjectRepository : IMyObjectRepository { public MyObject GetByID(int id) { using (ISession session = SessionFactory.Instance.GetCurrentSession()) return session.Get<MyObject>(id); } } This allows code in the application to be called as such: IMyObjectRepository repo = new MyObjectRepository(); MyObject obj = repo.GetByID(1); I have a suspicion my repository code is to blame, but I'm not 100% sure on the actual implementation I should be using. I found a similar issue on SO here. I too am using WebSessionContext in my implementation, however, no solution was provided other than writing a custom SessionManager. For simple CRUD operations, is a custom session provider required apart from the built in tools(ie WebSessionContext)?

• Problem with USB drivers (Windows-XP)

  - by Carl

  I obtained the drivers from the manufacturer for my HT-Link NEC USB 2.0 2-port Cardbus card. When I plugged in the card before I got the drivers, 3 new entries showed up in the Device Manager - two "NEC PCI to USB Open Host Controller" and one "Standard Enhanced PCI to USB Host controller." With the card plugged in, I uninstalled those two drivers. I then removed the card. I copied the new drivers to c:\windows\system32\drivers and the .inf file to c:\windows\inf. I also copied the drivers & inf to a new directory called c:\windows\drivers\ousb2. I reinserted the card. Windows automatically installed the same drivers as before. I selected 'update driver' on the "NEC PCI to USB..." entry and didn't see any other options. I then selected 'have disk' and pointed to c:\windows\drivers\ousb2 and got a message "The specified location does not contain information about your hardware." I then selected 'update driver' on the "Standard Enhanced PCI to USB...," and manually selected "USB 2.0 Enhanced Host Controller" (OWC 4/15/2003 2.1.3.1). Windows then automatically found a USB root hub, and I manually selected "USB 2.0 Root Hub Device" (OWC 4/15/2003 2.1.3.1). Now there are two sections in the Device Manager titled "Universal Serial Bus controllers." I plugged in my external USB hard disk adapter, and "USB Mass Storage Device" was added to the first set. Here's how it looks (w/drivers from the properties): [Universal Serial Bus controllers] Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD (6/1/2002 5.1.2600.0) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C2 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C4 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C7 (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) USB Mass Storage Device USB Root Hub (7/1/2001 5.1.2600.5512) (5 more USB Root Hubs - same driver) [Universal Serial Bus controllers] USB 2.0 Enhanced Host Controller (OWC 4/15/2003 2.1.3.1) USB 2.0 Root Hub Device (OWC 4/15/2003 2.1.3.1) When I unplug the card the two "NEC PCI to USB..." entries in the first set disappear, and the whole second set disappears. (I unplugged the hard disk adapter first...) The hard disk adapter still doesn't work in that Cardbus card with the new drivers. I don't think the above looks right - a second set of USB controllers listed in the Device Manager, and the NEC entries still in the first set, and the the USB mass storage device still in the first set. Any help appreciated. (Windows XP PRO SP3 w/all current updates.)

• Optimizing a shared buffer in a producer/consumer multithreaded environment

  - by Etan

  I have some project where I have a single producer thread which writes events into a buffer, and an additional single consumer thread which takes events from the buffer. My goal is to optimize this thing for a single machine to achieve maximum throughput. Currently, I am using some simple lock-free ring buffer (lock-free is possible since I have only one consumer and one producer thread and therefore the pointers are only updated by a single thread). #define BUF_SIZE 32768 struct buf_t { volatile int writepos; volatile void * buffer[BUF_SIZE]; volatile int readpos;) }; void produce (buf_t *b, void * e) { int next = (b->writepos+1) % BUF_SIZE; while (b->readpos == next); // queue is full. wait b->buffer[b->writepos] = e; b->writepos = next; } void * consume (buf_t *b) { while (b->readpos == b->writepos); // nothing to consume. wait int next = (b->readpos+1) % BUF_SIZE; void * res = b->buffer[b->readpos]; b->readpos = next; return res; } buf_t *alloc () { buf_t *b = (buf_t *)malloc(sizeof(buf_t)); b->writepos = 0; b->readpos = 0; return b; } However, this implementation is not yet fast enough and should be optimized further. I've tried with different BUF_SIZE values and got some speed-up. Additionaly, I've moved writepos before the buffer and readpos after the buffer to ensure that both variables are on different cache lines which resulted also in some speed. What I need is a speedup of about 400 %. Do you have any ideas how I could achieve this using things like padding etc?

• XenServer migrate machines between hosts

  - by Hubert Kario

  I have a XenServer 5.6 Free setup with 5 VMs (Windows and Linux) using about 1.5TB of directly attached storage. Because our virtualisation needs have grown a bit, we currently are preparing a faster XenServer 6.0 Free machine with more RAM and a more storage. Again, directly attached disks. How can I migrate the VMs between XenServer machines? I don't need to keep the machines up and running during migration, but using VM export and import would definitely take too long. Would making a VM with the same configuration on new host and dd'ing the LVM volume over network be the only quick and least painful solution? Are there any "gotchas" I should look out for when doing something like this? The old machine has an AMD Phenom II, the new has Intel Xeon E5 CPUs.

• What is the safest and least expensive way to store 10 terabytes of data?

  - by Josh T

  I'm a member of a production company and we're preparing for our first feature film. We've been discussing methods of data storage to keep all of our original content safe (for as long as possible). While we understand data is never 100% safe, we'd like to find the safest solution for us. We've considered: 16TB NAS for on-site storage 4-5 2TB hard drives (cheap, but not redundant), copy original footage to drives then seal in static free bag Burn data to Blu-Ray disks (time consuming and expensive: 200 disks == $5000) Tape drive(s)? I know the least about tape drives, except the fact that they're more reliable than disks. Any experience/knowledge with this amount of data is hugely appreciated.

• ASP.NET Session Management - which SQL Server option?

  - by frumious

  We're developing some custom web parts for our WSS 3 intranet, and have just run into something we'd like to use ASP.NET sessions for. This isn't currently enabled on the development server. We'd like to use SQL Server as the storage mechanism, because the production environment is a web farm with very simple load-balancing. There are 3 options you can choose from to set up the SQL Server session storage, tempdb, default separate DB, named DB. Both tempdb and default separate DB create a new DB to store certain information in; tempdb stores the actual session info in tempdb, which doesn't survive a reboot, and default separate DB stores everything in the new DB. Since you've got to create the new DB either way, my question is this: why would you ever choose to store the session info in tempdb? The only thing I can think of is if you'd like to have the ability to wipe the session by rebooting the server, but that seems quite apocalyptic!

• Very slow guards in my monadic random implementation (haskell)

  - by danpriduha

  Hi! I was tried to write one random number generator implementation, based on number class. I also add there Monad and MonadPlus instance. What mean "MonadPlus" and why I add this instance? Because of I want to use guards like here: -- test.hs -- import RandomMonad import Control.Monad import System.Random x = Rand (randomR (1 ::Integer, 3)) ::Rand StdGen Integer y = do a <-x guard (a /=2) guard (a /=1) return a here comes RandomMonad.hs file contents: -- RandomMonad.hs -- module RandomMonad where import Control.Monad import System.Random import Data.List data RandomGen g => Rand g a = Rand (g ->(a,g)) | RandZero instance (Show g, RandomGen g) => Monad (Rand g) where return x = Rand (\g ->(x,g)) (RandZero)>>= _ = RandZero (Rand argTransformer)>>=(parametricRandom) = Rand funTransformer where funTransformer g | isZero x = funTransformer g1 | otherwise = (getRandom x g1,getGen x g1) where x = parametricRandom val (val,g1) = argTransformer g isZero RandZero = True isZero _ = False instance (Show g, RandomGen g) => MonadPlus (Rand g) where mzero = RandZero RandZero `mplus` x = x x `mplus` RandZero = x x `mplus` y = x getRandom :: RandomGen g => Rand g a ->g ->a getRandom (Rand f) g = (fst (f g)) getGen :: RandomGen g => Rand g a ->g -> g getGen (Rand f) g = snd (f g) when I run ghci interpreter, and give following command getRandom y (mkStdGen 2000000000) I can see memory overflow on my computer (1G). It's not expected, and if I delete one guard, it works very fast. Why in this case it works too slow? What I do wrong?

• ControlCollection extension method optimazation

  - by Johan Leino

  Hi, got question regarding an extension method that I have written that looks like this: public static IEnumerable<T> FindControlsOfType<T>(this ControlCollection instance) where T : class { T control; foreach (Control ctrl in instance) { if ((control = ctrl as T) != null) { yield return control; } foreach (T child in FindControlsOfType<T>(ctrl.Controls)) { yield return child; } } } public static IEnumerable<T> FindControlsOfType<T>(this ControlCollection instance, Func<T, bool> match) where T : class { return FindControlsOfType<T>(instance).Where(match); } The idea here is to find all controls that match a specifc criteria (hence the Func<..) in the controls collection. My question is: Does the second method (that has the Func) first call the first method to find all the controls of type T and then performs the where condition or does the "runtime" optimize the call to perform the where condition on the "whole" enumeration (if you get what I mean). secondly, are there any other optimizations that I can do to the code to perform better. An example can look like this: var checkbox = this.Controls.FindControlsOfType<MyCustomCheckBox>( ctrl => ctrl.CustomProperty == "Test" ) .FirstOrDefault();

• How to exit current activity to homescreen (without using "Home" button)?

  - by steff

  Hi everyone, I am sure this will have been answered but I proved unable to find it. So please excuse my redundancy. What I am trying to do is emulating the "Home" button which takes one back to Android's homescreen. So here is what causes me problems: I have 3 launcher activities. The first one (which is connected to the homescreen icon) is just a (password protected) configuration activity. It will not be used by the user (just admin) One of the other 2 (both accessed via an app widget) is a questionnaire app. I'm allowing to jump back between questions via the Back button or a GUI back button as well. When the questionnaire is finished I sum up the answers given and provide a "Finish" button which should take the user back to the home screen. For the questionnaire app I use a single activity (called ItemActivity) which calls itself (is that recursion as well when using intents?) to jump from one question to another: Questionnaire.serializeToXML(); Intent i = new Intent().setClass(c, ItemActivity.class); if(Questionnaire.instance.getCurrentItemNo() == Questionnaire.instance.getAmountOfItems()) { Questionnaire.instance.setCompleted(true); } else Questionnaire.instance.nextItem(); startActivity(i); The final screen shows something like "Thank you for participating" as well as the formerly described button which should take one back to the homescreen. But I don't really get how to exit the Activity properly. I've e.g. used this.finish(); but this strangely brings up the "Thank you" screen again. So how can I just exit by jumping back to the homescreen?? Sorry for the inconvinience. Regards, Steff

• php include path problem:Same code works on Ubuntu default Apache and php conf, but not on CentOS

  So the same code works on my ubuntu server but when I upload it to my dedicated hosting server running CentOS it seems to add an extra prefix of .:/usr/share/pear:/usr/share/php: I tried setting includepath to different things but it just doesn't work. the file is in a directory called language in the same folder as the file that is including it and I'm using : include dirname(FILE).DIRECTORY_SEPARATOR."language".DIRECTORY_SEPARATOR."storage.inc"; and include dirname(__FILE__)."/language/language.php"; and include "language/language.php"; and alot of other combinations but I can't get it to find the file. Fatal error: require_once() [function.require]: Failed opening required '/home/neo/public_html/migration/include/class/core/storage.inc' (include_path='.:/usr/share/pear:/usr/share/php:/home/neo/public_html/migration') in /home/neo/public_html/migration/include/class/core/class_lang.inc on line 153

• Software/FakeRAID: Windows 8 Disk Mirroring vs Intel Onboard

  - by Johnny W

  So Windows 8 is out and I have a new motherboard. I wish to create a RAID 1 coupling between two HDDs -- for storage purposes only (my OS is on an SSD) -- but I don't know which is the best route to take. My motherboard (Z77 chipset) comes with the age old Intel Fake RAID, but since I only wish to use my RAID for storage, I wondered if I might be better to use Windows 8 Disk Mirroring. Can anyone advise which is better? Or perhaps the pros and cons of each, if that's too contentious? I just can't see the benefit of FakeRAID. You can see my current setup here, if that might change things(?): Thanks!

• Unattended Install of SQL Server 2005 Express with LOCAL Server InstanceName

  - by Jeff

  I'm creating an install package using InnoSetup and installing SQL Server 2005 Express. Here's the code below that appears in my RUN section: Filename: "{app}\SQL Server 2005 Express\SQLEXPR.exe" ; Parameters: "-q /norebootchk /qn reboot=ReallySuppress addlocal=all INSTANCENAME=(LOCAL) SCCCHECKLEVEL=IncompatibleComponents:1;MDAC25Version:0 ERRORREPORTING=2 SQLAUTOSTART=1 SAPWD=passwordhere SECURITYMODE=SQL"; WorkingDir: {app}\SQL Server 2005 Express; StatusMsg: Installing Microsoft SQL Server 2005 Express... Please Wait...;Check:SQLVerifyInstall What I'm trying to accomplish is have the SQL Server package install but only have the instance name itself reference the name of the machine name and nothing more. What I'm receiving instead is a named instance instead of local such as MachineName\SQLEXPRESS which is not what I want to receive. I need a local instance instead of a named instance due to the way my code is written to be able to install and talk with the databases in question. I would change it, trust me, were it not the fact that this install package is a replacement to a previous package that used the MSDE installer. I have to be able to support both through code. Any suggestions are welcome but a clear and concise method to get the installer to quietly install using only the machine name is my main goal. Thanks for the help and support!
