• Valueurl Binding On Large Arrays Causes Sluggish User Interface

  - by Hooligancat

  I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!

• Why is cell phone software is still so primitive?

  - by Tomislav Nakic-Alfirevic

  I don't do mobile development, but it strikes me as odd that features like this aren't available by default on most phones: full text search: searches all address book contents, messages, anything else being a plus better call management: e.g. a rotating audio call log, meaning you always have the last N calls recorded for your listening pleasure later (your little girl just said her first "da-da" while you were on a business trip, you had a telephone job interview, you received complex instructions to do something etc.) bluetooth remote control (like e.g. anyRemote, but available by default on a bluetooth phone) no multitasking capabilities worth mentioning and in general no e.g. weekly software updates, making the phone much more usable (even if it had to be done over USB, rather than over the network). I'm sure I was dumbfounded by the lack or design of other features as well, but they don't come to mind right now. To clarify, I'm not talking about smartphones here: my plain, 2-year old phone has a CPU an order of magnitude faster than my first PC, about as much storage space and it's ridiculous how bad (slow, unwieldy) the software is and it's not one phone or one manufacturer. What keeps the (to me) obvious software functionality vacuum on a capable hardware platform from being filled up?

• Register filetype with the browser?

  - by Lord.Quackstar

  In Android, I am trying to make it so that the user downloads a font from the browser, and I am able to view the font when downloaded. After multiple issues, I still have one lingering one: Registering the filetype with the browser. When trying to download with the Emulator (2.1-u1), I get "Cannot download. The content is not supported on this phone". Okay, so maybe its my manifest file. Updated with this: <activity android:name=".MainActivity" android:label="MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> <catagory android:name="android.intent.category.BROWSABLE"/> <data android:scheme="http"/> <data android:scheme="https"/> <data android:scheme="ftp"/> <data android:host="*"/> <data android:mimeType="*/*"/> <data android:pathPattern=".*zip"/> </intent-filter> </activity> Went back to the browser, and fails again. Restart the Emulator, still fails. Note that I got this format from posts here. Any suggestions on what to do?

• Link checker ; how to avoid false positives

  - by Burnzy

  I'm working a on a link checker/broken link finder and I am getting many false positives, after double checking I noticed that many error codes were returning webexceptions but they were actually downloadable, but in some other cases the statuscode is 404 and i can access the page from the browse. So here is the code, its pretty ugly, and id like to have something more, id say practical. All the status codes are in that big if are used to filter the ones i dont want to add to brokenlink because they are valid links ( i tested them all ). What i need to fix is the structure (if possible) and how to not get false 404. Thank you! try { HttpWebRequest request = ( HttpWebRequest ) WebRequest.Create ( uri ); request.Method = "Head"; request.MaximumResponseHeadersLength = 32; // FOR IE SLOW SPEED request.AllowAutoRedirect = true; using ( HttpWebResponse response = ( HttpWebResponse ) request.GetResponse() ) { request.Abort(); } /* WebClient wc = new WebClient(); wc.DownloadString( uri ); */ _validlinks.Add ( strUri ); } catch ( WebException wex ) { if ( !wex.Message.Contains ( "The remote name could not be resolved:" ) && wex.Status != WebExceptionStatus.ServerProtocolViolation ) { if ( wex.Status != WebExceptionStatus.Timeout ) { HttpStatusCode code = ( ( HttpWebResponse ) wex.Response ).StatusCode; if ( code != HttpStatusCode.OK && code != HttpStatusCode.BadRequest && code != HttpStatusCode.Accepted && code != HttpStatusCode.InternalServerError && code != HttpStatusCode.Forbidden && code != HttpStatusCode.Redirect && code != HttpStatusCode.Found ) { _brokenlinks.Add ( new Href ( new Uri ( strUri , UriKind.RelativeOrAbsolute ) , UrlType.External ) ); } else _validlinks.Add ( strUri ); } else _brokenlinks.Add ( new Href ( new Uri ( strUri , UriKind.RelativeOrAbsolute ) , UrlType.External ) ); } else _validlinks.Add ( strUri ); }

• YUI "Get" utility to parse JSON response?

  - by Sean

  The documentation page for the YUI "Get" utility says: Get Utility is ideal for loading your own scripts or CSS progressively (lazy-loading) or for retrieving cross-domain JSON data from sources in which you have total trust. ...but doesn't have any actual examples for how to do so. Their one example doesn't actually request a JSON document from a remote server, but instead a document containing actual JavaScript along with the JSON data. I'm just interested in the JSON response from the Google Maps API HTTP (REST) interface. Because I can't do cross-site scripting with the "Connect" utility, I am trying the "Get" utility. But merely inserting some JSON data into the page isn't going to do anything, of course. I have to assign it to a variable. But how? Also, just inserting JSON data into the page makes Firefox complain that there's a JavaScript error. And understandably! Plain ol' JSON data isn't going to parse as valid JavaScript. Any ideas?

• Send document to printer from web page

  - by FiveTools

  I have a webpage that activates a print job on a printer. This works in the localhost environment but does not work when the application is deployed to the webserver. I'm using the PrintDocument class from the .net System.Drawing.Print namespace. I'm now assuming the printer has to be available to the application on the remote server? Any suggestions on how I would get this to work? PrintDocument pd = new PrintDocument(); PaperSource ps = new PaperSource(); pd.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("Custom", 1180, 850); pd.PrintPage += new PrintPageEventHandler (this.pd_PrintPage); // Set your printer's name. Obtain from // System's Printer Dialog Box. pd.PrinterSettings.PrinterName = "Okidata ML 321 Turbo/D (IBM)"; //PrintPreviewDialog dlgPrintPvw = new PrintPreviewDialog(); //dlgPrintPvw.Document = pd; //dlgPrintPvw.Focus(); //dlgPrintPvw.ShowDialog(); pd.Print();

• 550 Error When I try to get the size of a file on an FTP

  - by Eric

  I'm trying to use an FtpWebRequest to get the size of a file on a company FTP. Yet whenever I try to get the response an exception is thrown. See the error details in the catch block in the code below. string uri = "ftp://ftp.domain.com/folder/folder/file.xxx"; FtpWebRequest sizeReq = (FtpWebRequest)WebRequest.Create(uri); sizeReq.Method = WebRequestMethods.Ftp.GetFileSize; sizeReq.Credentials = cred; sizeReq.UsePassive = proj.ServerConfig.UsePassive; //true sizeReq.UseBinary = proj.ServerConfig.UseBinary; //true sizeReq.KeepAlive = proj.ServerConfig.KeepAlive; //false long size; try { //Exception thrown here when I try to get the response using (FtpWebResponse fileSizeResponse = (FtpWebResponse)sizeReq.GetResponse()) { size = fileSizeResponse.ContentLength; } } catch(WebException exp) { FtpWebResponse resp = (FtpWebResponse)exp.Response; MessageBox.Show(exp.Message); // "The remote server returned an error: (550) File unavailable (e.g., file not found, no access)." MessageBox.Show(exp.Status.ToString()); //ProtcolError MessageBox.Show(resp.StatusCode.ToString()); // ActionNotTakenFileUnavailable MessageBox.Show(resp.StatusDescription.ToString()); //"550 SIZE: Operation not permitted\r\n" } This code does work, however, when connected to my personal FTP. The StatusDescription of the response says that the operation is "not permitted". Could it be that my office FTP just wont allow for the querying of a file size? I've also tried listing the directory details, which will return the size, and have noticed that my office FTP reports the directory details in a different format then my personal FTP. Maybe this is the problem? //work ftp ListDirectoryDetails -rw-r--r-- 1 (?) user 12345 Nov 16 20:28 some file name.xxx //personal ftp ListDirectoryDetails -rw-r--r-- 1 user user 12345 Mar 13 some file name.xxx From reading this blog post I think that my personal ftp is returning a Unix formatted response, but my work is returning a windows formatted response. Maybe this is unrelated but I thought I'd mention it.

• Is there the equivalent of cloud computing for modems?

  - by morpheous

  I asked this question on SF, and someone recommended that I ask it here - (I don't think I have enough points to move a question from SF to SO - and in any case, I don't know how to do it - so here is the question again): I am interested in the concept of PAAS (platform as a service). However, all talk about SAAS/PAAS seems to focus on only the computer itself - not its peripherals. Is it possible to 'outsource' modems as a resource - so that an app running remotely can pump data to a modem in the cloud? As a bit of background to the question, a group of us are thinking of starting a company that offers similar services to companies like twilio etc - but I want to 'outsource' both the computing hardware (thats PAAS - the easy bit) and the modems (thats what I cant seem to find any info on). Does anyone know if modems can be bundled as part of a PAAS service? - alternatively, is there a way that an application running on one computer can communicate (i.e. pump data) to a remote modem residing on another machine?. I assume I can come up with some protocol over UDP or TCP - but there is no point reinventing the wheel - if such a protocol like that already exists (or if it some open source software allows one to do this). Any suggestions on how to solve this problem?

• Execute javascript on IIS server

  - by James Westgate

  I have the following situation. A customer uses JavaScript with jQuery to create a complex website. We would like to use JavaScript and jQuery on the server (IIS) for the following reasons: Skills transfer - we would like to use JavaScript and jQuery on the server and not have to use eg VB Script. / classic asp. .Net framework/Java etc is ruled out because of this. Improved options for search/accessibility. We would like to be able to use jQuery as a templating system, but this isn't viable for search engines and users with js turned off - unless we can selectively run this code on the server. There is significant investment in IIS and Windows Server, so changing that is not an option. I know you can run jScript on IIS using windows Script host, but am unsure of the scalability and the process surrounding this. I am also unsure whether this would have access to the DOM. Here is a diagram that hopefully explains the situation. I was wondering if anyone has done anything similar?

• Flash - Uploading to and Downloading from localhost

  - by Md Derf

  I have an online flash application that acts as a front end for a server application built in delphi. The server can be installed/used on a remote computer or a personal version can be downloaded and the Flash app pointed at localhost to use it. However, Flash has issues with using the POST and GET functions on the localhost, which makes uploading data files and downloading results files difficult. To get past the difficulty with downloading results files I'm planning to just have the server app serve the results file as an attachment and have the Flash app open the address of the file up in another browser window using external interface. First off, is this likely to cause similar security issues? I.E. Flash will see "localhost" in the external interface call and stop it from working the same as when I try to use POST/GET functions with localhost? Secondly, for upload this seems just a bit little trickier, I'm planning on doing something similar, having flash use external interface to open a php script for a file upload. Is this feasible and, again, will Flash still have security issues? Lastly, if anyone knows how to get flash to execute POST and GET functions with localhost addresses, I'd love to have that information to avoid all this jumping through hoops.

• How to verify the SSL connection when calling an URI?

  - by robertokl

  Hello, I am developing an web application that is authenticated using CAS (A single-sign-on solution: http://www.ja-sig.org/wiki/display/CAS/Home). For security reasons, I need two things to work: The communication between CAS and my application needs to be secure My application needs to accept the certification coming with CAS, so that I can guarantee that the CAS responding is the real CAS Server. This is what I got so far: uri = URI.parse("https://www.google.com/accounts") https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = (uri.scheme == 'https') https.verify_mode = (OpenSSL::SSL::VERIFY_PEER) raw_res = https.start do |conn| conn.get("#{uri.path}?#{uri.query}") end This works just great in my Mac OSX. When I try to reach an insecure uri, it raises an exception, and when I try to reach a secure uri, it allow me normally, just like expected. The problem starts when I deploy my application on my Linux server. I tried in both Ubuntu and Red Hat. Independing of what uri I try to reach, it always raises me this exception: OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:553:in `do_start' from /usr/local/lib/ruby/1.8/net/http.rb:542:in `start' from (irb):7 I think this have something to do with my installed OpenSSL package, but I can't be sure. This are my installed OpenSSL packages: openssl.x86_64 0.9.8e-12.el5 installed openssl-devel.x86_64 0.9.8e-12.el5 installed I tried using HTTParty as well, but it just ignores the SSL certificated. I hope someone can help me, either by telling me a gem that works the way I need. Thanks.

• nested include in php

  - by aeonsleo

  The directory structure: C:/wamp/www/application/model/data_access/data_object.php C:/wamp/www/application/model/users/user.class.php C:/wamp/www/application/controller/projects.php C:/wamp/www/application/controller/links/links.php I have 2 php files data_object.php and user.class.php Now user.class.php has an include statement for data_object.php wchih is relative to user.class.php.These two files are under different directory hierarchy. Now I have to include this user.class.php in various files (like projects.php, links.php-which themselves are under different hierarchy) whenever i want to create a User() object. The problem is the relative path for file inclusion of data_object.php does work for say projects.php but if i open links.php the error message says it could not open file data_object.php in user.class.php. What i think is for relative inclusion of data_object.php it is considering the path of the file in which user.class.php is included. I am facing such problems in more than one scenarios I have to keep my directory structure the way it is but have to find a way to work with nested includes. I used Document root of session it give root path as C:/wamp/www/ i appended the path for data_object.php include but this is not working. (note: the forward slash is present after www) I am currently running on wamp server's localhost but after completion i have to host the solution on a domain. Pls help

• Can I output/flush data to screen while processing ajax page?

  - by Bee

  I need to display on my page a list of records pulled from a table. Ajax works fine (I query the database and put all the data inside a on the main page) but if I have lots of records (say 500+) it will hang until data is fully loaded, THEN it will be sent back to the page and correctly displayed. I would like to be able to display the records on the page while getting them, instead of being forced to wait until completion. I am trying with flush(); inside the remote (ajax) page but it still waits until full data is loaded. This is what I currently have inside the ajax page: At the very beginning: @apache_setenv('no-gzip', 1); @ini_set('zlib.output_compression', 0); @ini_set('implicit_flush', 1); for ($i = 0; $i < ob_get_level(); $i++) { ob_end_flush(); } ob_implicit_flush(1); Then whenever I have a echo call: ob_flush(); Now if I load the ajax page alone... it will list the records while reading them from the database. But if I call the same page via Ajax, it will hang and send all the data at once. Any idea? This is the function I use to get the ajax content ('id' is the target , 'url' refers to the ajax page that runs the database query to list the records): function ajax(id,url) { xmlhttp=new XMLHttpRequest(); xmlhttp.open("GET",url,false); xmlhttp.send(null); document.getElementById(id).innerHTML = parseScript(xmlhttp.responseText); }

• send arrow keys using ganymed ssh java

  - by José Ramón Pérez Rubio

  I am using Ganymed ssh to connect to a remote machine and apart from sending commands I need to send the arrows keys (left and right keys). I can send commands but when I send the arrows keys nothing happends. This is what I have: public boolean createShell() throws Exception { try { // ... m_session= connection.openSession(); m_commandWriter = new OutputStreamWriter(m_session.getStdin()); String encoding=m_commandWriter.getEncoding(); //encoding is UFT8 m_errorPipe=new SSHSyncPipe(m_session.getStderr()); m_outputPipe=new SSHSyncPipe(m_session.getStdout()); m_outputPipe.start(); m_errorPipe.start(); // m_session.requestPTY("bash"); m_session.requestDumbPTY(); m_session.startShell(); m_shellCreated=true; return true; } } So if I use m_commandWriter.write(ls"\r\n"); m_commandWriter.flush(); It works, but m_commandWriter.write(37);//37 is the code for left arrow m_commandWriter.flush(); Doesn't work. Does anyone know what I am doing wrong? Thank you

• Publishing artifacts with sources on archiva

  - by Palimondo

  At work I'm dipping my toes in managing project dependencies with maven. We use Apache Archiva (1.2.1) as a local repository and proxy. I'm adding artifact for open source project, that is not published on any public repository. I've learned that to publish the sources I should use the Classifier field on Upload artifact page. The sources are then listed alongside the jar and pom when I browse the repository. But when I update my maven dependencies I get only the jar and pom from the repository. I noticed that sources are also missing when the archiva proxies for me the downloads from other public repositories. I didn't find any configuration options in Archiva's admin pages to serve the sources... What am I missing? Update: I was missing the fact that artifact sources have to be downloaded manually. I.e. the maven client has to request them, which is controlled by command line option -DdownloadSources=true. Maven Integration for Eclipse has a preference setting to always download them as described in Resolving artifact sources. Archiva then serves the sources for local artifacts or proxies the request to remote repositories and caches the sources for future requests.

• problem with mysql character set & GWT

  - by Ehsan Khodarahmi

  Hi I've a SmartGWT application which interacts with a mysql database using rpc services. Suppose it as a simple form with a textbox & two save & load buttons. My database & tables & all fields collation is utf8_persian_ci. All java source files & module html & xml files have saved with utf8 character set. & also I've a meta tag in module html file which contains my form : <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> my application works correctly in eclipse develpment mode & also in my local tomcat server. Then i put it on remote server (I compress it using jar.exe into a war file with -cvf flag & then upload it using my server's plesk control panel). In this mode, when I load data from a mysql table (load a record from any table), data will load into my form with no problem, but when I want to save some data (in persian language), mysql just writes some ? (question sign) in characteristic table fields. Any idea ?

• Request for the permission of type 'System.Web.AspNetHostingPermission' when compiling web site

  - by ahsteele

  I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines I would change the machine's .NET Security Configuration to trust the local intranet. I believe this configuration utility relied upon the mscorcfg.msc which from some cursory research appears to be apart of the .NET 2.0 SDK. I have tried to follow the instructions from this Microsoft Support article running the command below to no avail.

• Ruby ICalendar Gem: How to get e-mail reminders working.

  - by Jenny

  I'm trying to work out how to use the icalendar ruby gem, found at: http://icalendar.rubyforge.org/ According to their tutorial, you do something like: cal.event.do # ...other event properties alarm do action "EMAIL" description "This is an event reminder" # email body (required) summary "Alarm notification" # email subject (required) attendees %w(mailto:[email protected] mailto:[email protected]) # one or more email recipients (required) add_attendee "mailto:[email protected]" remove_attendee "mailto:[email protected]" trigger "-PT15M" # 15 minutes before add_attach "ftp://host.com/novo-procs/felizano.exe", {"FMTTYPE" => "application/binary"} # email attachments (optional) end alarm do action "DISPLAY" # This line isn't necessary, it's the default summary "Alarm notification" trigger "-P1DT0H0M0S" # 1 day before end alarm do action "AUDIO" trigger "-PT15M" add_attach "Basso", {"VALUE" => ["URI"]} # only one attach allowed (optional) end So, I am doing something similar in my code. def schedule_event puts "Scheduling an event for " + self.title + " at " + self.start_time start = self.start_time endt = self.start_time title = self.title desc = self.description chan = self.channel.name # Create a calendar with an event (standard method) cal = Calendar.new cal.event do dtstart Program.convertToDate(start) dtend Program.convertToDate(endt) summary "Want to watch" + title + "on: " + chan + " at: " + start description desc klass "PRIVATE" alarm do action "EMAIL" description desc # email body (required) summary "Want to watch" + title + "on: " + chan + " at: " + start # email subject (required) attendees %w(mailto:[email protected]) # one or more email recipients (required) trigger "-PT25M" # 25 minutes before end end However, I never see any e-mail sent to my account... I have even tried hard coding the start times to be Time.now, and sending them out 0 minutes before, but no luck... Am I doing something glaringly wrong?

• How should I manage my many-to-many relationships?

  - by wes

  Hello all, I have a database containing a couple tables: files and users. This relationship is many-to-many, so I also have a table called users_files_ref which holds foreign keys to both of the above tables. Here's the schema of each table: files - file_id, file_name users - user_id, user_name users_files_ref - user_file_ref_id, user_id, file_id I'm using Codeigniter to build a file host application, and I'm right in the middle of adding the functionality that enables users to upload files. This is where I'm running into my problem. Once I add a file to the files table, I will need that new file's id to update the users_files_ref table. Right now I'm adding the record to the files table, and then I imagined I'd run a query to grab the last file added, so that I can get the ID, and then use that ID to insert the new users_files_ref record. I know this will work on a small scale, but I imagine there is a better way of managing these records, especially in a heavy-traffic scenario. I am new to relational database stuff but have been around PHP for a while, so please bear with me here :-) I have primary and foreign keys set up correctly for the files, users, and users_files_ref tables, I'm just wondering how to manage the adding of file records for this scenario? Thanks for any help provided, it's much appreciated. -Wes

• How to convert a printer driver to a stand-alone console application which can generate a printer fi

  - by Thorbjørn Ravn Andersen

  I have a situation where the only way to generate a certain datafile is to print it manually to FILE: under Windows and save it in a file for further processing. I would really like to have a small stand-alone program which embeds this binary printer driver so I can run it from a batch file and have it generate that binary file for me, as we can then fully automate the "save file in Visio, 'print' it and upload it to the final destination and trigger a remote test". Is this possible with a suitable Windows SDK? I am a Java programmer, so I do not know Visual Studio and the possibilities with MSDN - yet! - but I'd appreciate pointers. EDIT: I have the installation files for that printer driver, both 32 and 64 bit. Older versions may include a 16 bit driver. EDIT: The "print to FILE:" functionality is just what was recommended by the documentation. I have played a little bit with using the LPR-protocol to see what it can do. I'd still prefer the "invoke small binary" approach.

• localhost not going to desired VirtualHost

  - by ladaghini

  I have several VirtalHosts set up on my computer. I'd like to visit the site I'm currently working on from a different PC using the my comp's ip address, but every config i've tried keeps taking me to a different virtual host (in fact the first virtualhost I set up on my comp). How do I set up the apache virtualhost configs to ensure that the ip address takes me to the site I want it to. /etc/apache2/sites-available/site-i-want-to-show-up-with-ip-address.conf contains: <VirtualHost *:80> ServerAdmin webmaster@localhost ServerAlias currentsite.com DocumentRoot /path/to/root/of/site-i-want-to-show-up ServerName localhost ScriptAlias /awstats/ /usr/lib/cgi-bin/ CustomLog /var/log/apache2/current-site-access.log combined </VirtualHost> And /etc/apache2/sites-available/site-that-keeps-showing-up.conf contains: <VirtualHost *:80> ServerAdmin webmaster@localhost ServerAlias theothersite.com DocumentRoot /path/to/it <Directory /> Options FollowSymLinks AllowOverride None </Directory> </VirtualHost> I'd appreciate anyone's help. Also, I don't know too much about configuring web servers, and I used tutorials to get the above code.

• Optimize CUDA with Thrust in a loop

  - by macs

  Given the following piece of code, generating a kind of code dictionary with CUDA using thrust (C++ template library for CUDA): thrust::device_vector<float> dCodes(codes->begin(), codes->end()); thrust::device_vector<int> dCounts(counts->begin(), counts->end()); thrust::device_vector<int> newCounts(counts->size()); for (int i = 0; i < dCodes.size(); i++) { float code = dCodes[i]; int count = thrust::count(dCodes.begin(), dCodes.end(), code); newCounts[i] = dCounts[i] + count; //Had we already a count in one of the last runs? if (dCounts[i] > 0) { newCounts[i]--; } //Remove thrust::detail::normal_iterator<thrust::device_ptr<float> > newEnd = thrust::remove(dCodes.begin()+i+1, dCodes.end(), code); int dist = thrust::distance(dCodes.begin(), newEnd); dCodes.resize(dist); newCounts.resize(dist); } codes->resize(dCodes.size()); counts->resize(newCounts.size()); thrust::copy(dCodes.begin(), dCodes.end(), codes->begin()); thrust::copy(newCounts.begin(), newCounts.end(), counts->begin()); The problem is, that i've noticed multiple copies of 4 bytes, by using CUDA visual profiler. IMO this is generated by The loop counter i float code, int count and dist Every access to i and the variables noted above This seems to slow down everything (sequential copying of 4 bytes is no fun...). So, how i'm telling thrust, that these variables shall be handled on the device? Or are they already? Using thrust::device_ptr seems not sufficient for me, because i'm not sure whether the for loop around runs on host or on device (which could also be another reason for the slowliness).
