  • OpenCL: does it play well with OpenMP, can I connect other languages to it, etc.

    - by Cem Karan
    The 1.0 spec for OpenCL just came out a few days ago (Spec is here) and I've just started to read through it. I want to know if it plays well with other high performance multiprocessing APIs like OpenMP (spec) and I want to know what I should learn. So, here are my basic questions: If I am already using OpenMP, will that break OpenCL or vice-versa? Is OpenCL more powerful than OpenMP? Or are they intended to be complementary? Is there a standard way of connecting an OpenCL program to a standard C99 program (or any other language)? What is it? Does anyone know if anyone is writing an OpenCL book? I'm reading the spec, but I've found books to be more helpful.

  • How can I set up sendmail to forward all mail to an external MTA?

    - by unknown (google)
    We have multiple applications that currently talk SMTP to an external MTA. The emails have arbitrary destination domains (they're emails to be sent to our users), but all from the same internal domain ([email protected]). I want to set up an internal MTA (i guess with sendmail) that queues all mails, and have the internal MTA forward these emails to the external MTA, because the external MTA occasionally goes down and this causes various problems in our applications. I figure I can set up sendmail as a queuing middleware. If the above assumptions are correct, what would the sendmail configuration look like? The 'mailertable' feature looks promising, and so does 'SMART_HOST'. Any thoughts before I explore these possibilities? Jae

  • Dreamhost DNS CNAMEs work at my house, not for anyone else

    - by unknown (google)
    I have my domain BQQKSHELF.COM that I bought through Dreamhost. I set up a CNAME so that zach.bqqkshelf.com points to my app at zach.heroku.com. The app at Heroku is working fine. Everyone can agree on that. When I go to zach.bqqkshelf.com, everything seems to work okay too. When I ask my roommate to go to it, it works. When I go to it on my iTouch, it works. When I IM my friends and ask them to go to zach.bqqkshelf.com, they get a time out error. How is this possible?

  • iTunes Connect rejects my binary because I used a pre-release version of the SDK, what should I do?

    - by Prairiedogg
    NOTE - I'm posting this question to answer myself as a service to the community. Stay tuned for the answer. I downloaded a pre-release version of the iPhone SDK and tried to update one of my existing apps using a binary I built with it. Obviously you are not supposed to do this but I had forgotten about the warning when I installed the pre-release SDK. Anyway - I have two questions: Can I simply set the base SDK to an earlier version in the build settings and get around this problem? If not, then what should I do?

  • Please help me work out this error, regarding the use of a HTTPService to connect Flex4 & Ruby on Ra

    - by ben
    I have a HTTPService in Flash Builder 4, that is defined as follows: <s:HTTPService id="getUserDetails" url="http://localhost:3000/users/getDetails" method="GET"/> It gets called as follows: getUserDetails.send({'user[username]': calleeInput.text}); Here is a screenshot of the network monitor, showing that the parameter is being sent correctly (it is 'kirsty'): Here is the Ruby on Rails method that it's connected to: def getDetails @user = User.find_by_username(:username) render :xml => @user end When I run it, I get the following error output in the console: Processing UsersController#list (for 127.0.0.1 at 2010-04-30 17:48:03) [GET] User Load (1.1ms) SELECT * FROM "users" Completed in 30ms (View: 16, DB: 1) | 200 OK [http://localhost/users/list] Processing UsersController#getDetails (for 127.0.0.1 at 2010-04-30 17:48:13) [GET] Parameters: {"user"={"username"="kirsty"}} User Load (0.3ms) SELECT * FROM "users" WHERE ("users"."username" = '--- :username ') LIMIT 1 ActionView::MissingTemplate (Missing template users/getDetails.erb in view path app/views): app/controllers/users_controller.rb:36:in getDetails' /usr/local/lib/ruby/1.8/webrick/httpserver.rb:104:in service' /usr/local/lib/ruby/1.8/webrick/httpserver.rb:65:in run' /usr/local/lib/ruby/1.8/webrick/server.rb:173:in start_thread' /usr/local/lib/ruby/1.8/webrick/server.rb:162:in start' /usr/local/lib/ruby/1.8/webrick/server.rb:162:in start_thread' /usr/local/lib/ruby/1.8/webrick/server.rb:95:in start' /usr/local/lib/ruby/1.8/webrick/server.rb:92:in each' /usr/local/lib/ruby/1.8/webrick/server.rb:92:in start' /usr/local/lib/ruby/1.8/webrick/server.rb:23:in start' /usr/local/lib/ruby/1.8/webrick/server.rb:82:in `start' Rendering rescues/layout (internal_server_error) I'm not sure if the error is being caused by bad code in the getDetails Ruby on Rails method? I'm new to RoR, and I think I remember reading somewhere that every method should have a view. I'm just using this method to get info into the Flex 4 app, do I still need to make a view for it? Is that what's causing the error? Any help would be GREATLY appreciated, I've been stuck on this for a few days now! Thanks.

  • .net List<string>.Remove bug Should I submit a MS Connect bug report on this?

    - by Dean Lunz
    So I was beating my head against a wall for a while before it dawned on me. I have some code that saves a list of names into a text file ala ... System.IO.File.WriteAllLines(dlg.FileName, this.characterNameMasterList.Distinct().ToArray()); The character names can contain special characters. These names come from the wow armory at www.wowarmory.com There are about 26000 names or so saved in the .txt file. The names get saved to the .txt file just fine. I wrote another application that reads these names from that .txt file using this code // download the names from the db var webNames = this.DownloadNames("character"); // filter names and get ones that need to be added to the db var localNames = new List<string>(System.IO.File.ReadAllLines(dlg.FileName)); foreach (var name in webNames) { if (localNames.Contains(name.Trim())) localNames.Remove(name); } return localNames; ... the code downloads a list of names from my website that are already in the db. Then reads the local .txt file and singles out every name that is not yet in the db so it can later add it. The names that get read from the .txt file also get read just fine with no problems. The problem comes in when removing names from the localNames list. localNames is a List type. As soon as localNames.Remove(name) gets called any names in the list that had special characters in them would get corrupted and be converted into ? characters. See for screen cap http://yfrog.com/12badcharsp So i tried doing it another way using ... // download the names from web that are already in the db var webNames = this.DownloadNames("character"); // filter names and get ones that need to be added to the db var localNames = new List<string>(System.IO.File.ReadAllLines(dlg.FileName)); int index = 0; while (index < webNames.Count) { var name = webNames[index++]; var pos = localNames.IndexOf(name.Trim()); if (pos != -1) localNames.RemoveAt(pos); } return localNames; .. But using localNames.RemoveAt also corrupts the items in the list converting special characters into ?. So is this a known bug with the List.remove methods? Does anyone know? Has anyone else had this problem? I also used .NET Reflector to disassemble/inspect the list.remove and list.RemoveAt code and it appear to be calling some external Copy function. Aside from the fact that this is prob not the best way to get a unique list of items from 2 lists am I missing something or should be aware of when using the List.Remove methods ? I am running windows 7 vs2010 and my app is set for .net 4 (no client profile )

  • Can I connect to SQL Server using Windows Authentication from Java EE webapp?

    - by KG
    I am currently investigating how to make a connection to a SQL Server database from my Java EE web application using Windows Authentication instead of SQL Server authentication. I am running this app off of Tomcat 6.0, and am utilizing the Microsoft JDBC driver. My connection properties file looks as follows: dbDriver = com.microsoft.sqlserver.jdbc.SQLServerDriver dbUser = user dbPass = password dbServer = localhost:1433;databaseName=testDb dbUrl = jdbc:sqlserver://localhost:1433 I have zero problems with connecting to a SQL Server database in this fashion when using SQL Server authentication. Is there any way I can retrieve the credentials of the user's Windows Authentication and use that authentication for SQL Server? UPDATE: I know in ASP.net there is a way to set up Windows Authentication for access to the webapp, which is exactly what I am looking for, except I want to pass that token off to SQL Server for access to the database.

    I have an old IDE HDD that I am trying to pull files off of. I am using a USD to IDE/SATA adapter. I plug in the power and adapter plugs into the drive and it fires up. I plug the USB plug into my XP laptop and it installs the drivers. I can see USB Mass Storage Device under Device Manager. My problem is I can't see the drive in either Windows Explorer or under Disk Management under Computer Management. Not sure what I am doing wrong. Do I have to slave the old hdd? Do I have to make BIOS changes?

  • Translating CURL to FLEX HTTPRequests

    - by Joshua
    I am trying to convert from some CURL code to FLEX/ActionScript. Since I am 100% ignorant about CURL and 50% ignorant about Flex and 90% ignorant on HTTP in general... I'm having some significant difficulty. The following CURL code is from http://code.google.com/p/ga-api-http-samples/source/browse/trunk/src/v2/accountFeed.sh I have every reason to believe that it's working correctly. USER_EMAIL="[email protected]" #Insert your Google Account email here USER_PASS="secretpass" #Insert your password here googleAuth="$(curl https://www.google.com/accounts/ClientLogin -s \ -d Email=$USER_EMAIL \ -d Passwd=$USER_PASS \ -d accountType=GOOGLE \ -d source=curl-accountFeed-v2 \ -d service=analytics \ | awk /Auth=.*/)" feedUri="https://www.google.com/analytics/feeds/accounts/default\ ?prettyprint=true" curl $feedUri --silent \ --header "Authorization: GoogleLogin $googleAuth" \ --header "GData-Version: 2" The following is my abortive attempt to translate the above CURL to AS3 var request:URLRequest=new URLRequest("https://www.google.com/analytics/feeds/accounts/default"); request.method=URLRequestMethod.POST; var GoogleAuth:String="$(curl https://www.google.com/accounts/ClientLogin -s " + "-d [email protected] " + "-d Passwd=secretpass " + "-d accountType=GOOGLE " + "-d source=curl-accountFeed-v2" + "-d service=analytics " + "| awk /Auth=.*/)"; request.requestHeaders.push(new URLRequestHeader("Authorization", "GoogleLogin " + GoogleAuth)); request.requestHeaders.push(new URLRequestHeader("GData-Version", "2")); var loader:URLLoader=new URLLoader(); loader.dataFormat=URLLoaderDataFormat.BINARY; loader.addEventListener(Event.COMPLETE, GACompleteHandler); loader.addEventListener(IOErrorEvent.IO_ERROR, GAErrorHandler); loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, GAErrorHandler); loader.load(request); This probably provides you all with a good laugh, and that's okay, but if you can find any pity on me, please let me know what I'm missing. I readily admit functional ineptitude, therefore letting me know how stupid I am is optional.

  • WPF: How to connect to a sql ce 3.5 database with ADO.NET?

    - by EV
    Hi, I'm trying to write an application that has two DataGrids - the first one displays customers and the second one selected customer's records. I have generated the ADO.NET Entity Model and the connection property are set in App.config file. Now I want to populate the datagrids with the data from sql ce 3.5 database which does not support LINQ-TO-SQL. I used this code for the first datagrid in code behind: CompanyDBEntities db; private void Window_Loaded(object sender, RoutedEventArgs e) { db = new CompanyDBEntities(); ObjectQuery<Employees> departmentQuery = db.Employees; try { // lpgrid is the name of the first datagrid this.lpgrid.ItemsSource = departmentQuery; } catch (Exception ex) { MessageBox.Show(ex.Message); } However, the datagrid is empty although there are records in a database. It would also be better to use it in MVVM pattern but I'm not sure how does the ado.net and MVVM work together and if it is even possible to use them like that. Could anyone help? Thanks in advance.

My friend knows VB6 and she knows testing, but she and I are both wondering what is the relevance of VB6 to testing. Is there some well-known standard way to test applications using VB6 that my friend should learn for this interview?

  • dd clone hard drive: Input/Output Error though "chkdsk" says OK

    - by unknown (google)
    Hi, I've used dd to clone hard drives before using 'dd' and a live cd, but have run into a problem. The issue: dd fails with an "Input/Output Error" on /dev/sda3 , even though windows "check disk" (chkdsk) says it's ok. Context: Trying to replace my laptop hard drive w/ a faster one of the same size Laptop has NTFS on a 320gb hard drive Booting into knoppix Knoppix recognizes 'original' drive (/dev/sda) I am using a usb connection for ‘new' drive (irrelevant, but just an fyi) Knoppix recognizes the usb drive as /dev/sdb Using dd, as follows: dd if=/dev/sda of=/dev/sdb "dd" gives the I/O error above at 82Gb (out of 320Gb) I then tried checking each partition as follows and found it failed on /dev/sda3: dd if=/dev/sda1 of=/dev/null dd if=/dev/sda2 of=/dev/null dd if=/dev/sda3 of=/dev/null I have ran windows xp chkdsk on the offending drive in both "find only" and "find and fix" mode and it reports no errors Question How can I find and fix the error on my original hard drive partition (i.e. /dev/sda3) so that dd reads it successfully?

  • Should I trust Redis for data integrity?

    - by Jiaji
    In my current project, I have PostgreSQL as my master DB, and Redis as kind of a slave, e.g., when some user adds another as a friend, first the relationship will be stored in PostgreSQL and then a friend list in Redis will be updated. When some user's friend list is requested, it will be pulled out of Redis instead of PostgreSQL. The question is: when I update the friend list in Redis, should I get a fresh copy outof PostgreSQL, and replace the old list in Redis with the new one or should I keep the old list and simply SADD the userid into the list? The latter is of course best for performance, but intuitively the former does a better job in keep the data integrity? And if something like Celery is used, is the second method worth the risk?

  • NHibernate2 query is wired when fetch the collection from the proxy. Is this correct behavior?

    - by ensecoz
    This is my class: public class User { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IList<UserFriend> Friends { get; protected set; } } public class UserFriend { public virtual int Id { get; set; } public virtual User User { get; set; } public virtual User Friend { get; set; } } This is my mapping (Fluent NHibernate): public class UserMap : ClassMap<User> { public UserMap() { Id(x => x.Id, "UserId").GeneratedBy.Identity(); HasMany<UserFriend>(x => x.Friends); } } public class UserFriendMap : ClassMap<UserFriend> { public UserFriendMap() { Id(x => x.Id, "UserFriendId").GeneratedBy.Identity(); References<User>(x => x.User).TheColumnNameIs("UserId").CanNotBeNull(); References<User>(x => x.Friend).TheColumnNameIs("FriendId").CanNotBeNull(); } } The problem is when I execute this code: User user = repository.Load(1); User friend = repository.Load(2); UserFriend userFriend = new UserFriend(); userFriend.User = user; userFriend.Friend = friend; friendRepository.Save(userFriend); var friends = user.Friends; At the last line, NHibernate generate this query for me: SELECT friends0_.UserId as UserId1_, friends0_.UserFriendId as UserFrie1_1_, friends0_.UserFriendId as UserFrie1_6_0_, friends0_.FriendId as FriendId6_0_, friends0_.UserId as UserId6_0_ FROM "UserFriend" friends0_ WHERE friends0_.UserId=@p0; @p0 = '1' QUESTION: Why the query look very wired? It should select only 3 fields (which are UserFriendId, UserId, FriendId) Am I right? or there is something going on inside NHibernate?
