• How to do google webpage translate in a Java class

  - by Robert

  Hi,this is a follow-up question of mine. Suppose now I have a URL : http://www.baidu.com/s?bs=%B0%C2%B0%CD%C2%ED&f=8&wd=%B0%C2%B0%CD%C2%ED and it work perfectly by inputting it in the text field of google translate and select from "Chinese" to English. My question is ,suppose now I want to achieve this in Java, I would like to adopt "Process q=Runtime.getRuntime().exec( "cmd /c start +URL" approach to do this. Could I achieve that by simply concatenating the Google translate URL and the webpage URL? If yes,could you please elaborte,thanks.

• iPhone filesystem permissions POSIX-compliant?

  - by Seva Alekseyev

  Hi all, I'm trying to pass some files from one app to another. I communicate the path (via a custom URL). The target application cannot read the file, citing errno 13 (permission denied). I've checked the permissions on file - they're 0644 (O+R), the permissions on directories all the way up to the root are 755 (O+RX). From a POSIX perspective, the file should be readable to any process and any user. Yet it's not. Any ideas, please? I can think of some workarounds. I could use a Web service (upload, get a cookie, communicate the cookie to the other app, other app downloads). I could also pass the actual file data in the URL - unelegant, and probably subject to length limitations. Clipboard is not supported on iPhone OS 2 IIRC.

• Adding Listeners at runtime? - Java MVC

  - by Halo

  My model in my MVC pattern, generates components at runtime and gives them to the View to be displayed on the screen through update() method (you know, model is the observable and the view is the observer). But I also need to add listeners to these components, and the controller has the listener methods (because they say the MVC pattern is like this) and it's not involved in this update process. So I can't add the listeners at runtime, but only in the controller's constructor at startup. I've got an idea, that is making the controller the observer and then giving the data to the view, as well as adding the listeners. Do you think this would be OK?

• .Net Regular expression - how to do an exact match exclusion on a full string?

  - by Nathan Ridley

  I need a .Net regular expression that matches anything OTHER than the exact full string match specified. So basically: ^Index$ ... is the only exclusion I care about. Strings can start with, finish with or contain "Index", but not match exactly. My brain doesn't seem to be working today and I'm failing to work this one out. EDIT The answer MUST be via the pattern itself, as I am passing an argument to a third party library and do not have control over the process other than via the Regex pattern.

• Pre-allocate memory between HostApp and DLL

  - by Leo

  I have a DLL which provided a decoding function, as follows: function MyDecode (Source: PChar; SourceLen: Integer; var Dest: PChar; DestLen: Integer): Boolean; stdcall; The HostApp call "MyDecode", and transfer into the Source, SourceLen and Dest parameters, the DLL returns decoded Dest and DestLen. The problem is: The HostApp impossible to know decoded Dest length, and therefore would not know how to pre-allocated Dest's memory. I know that can split "MyDecode" into two functions: function GetDecodeLen (Source: PChar; SourceLen: Integer): Integer; stdcall; // Return the Dest's length function MyDecodeLen (Source: PChar; SourceLen: Integer; var Dest: PChar): Boolean; stdcall; But, My decoding process is very complicated, so if split into two functions will affect the efficiency. Is there a better solution?

• Launching an external application from within a NPAPI Plugin

  - by Adam Cobb

  I am trying to work out why an NPAPI plugin I have written, which works fine in terms of performing operations triggered via Javascipt calls, cannot use CreateProcess() or ShellExecute() to launch an application from a path specified via the Javascript call. I can seemingly use either of these methods and they return success, i.e. no error code. But the application just does not launch. I have tried modifying the parameters used when calling them, to create new process group etc. But seemingly with no effect. I know this may seem like a bit of a security risk, but for the very specific purpose we wish to use it for it shouldn't be a problem. Thanks.

• Why am I unable to Debug my ASP.NET website in Visual Studio?

  - by willem

  I used to be able to attach to my w3wp process and Debug my web application, but this is not working anymore. I have no idea what changed to break this. My breakpoints simply have the "breakpoint will currently not be hit. The source code is different from the original version." What I have tried: Did a solution Clean. Did a solution Rebuild. Deleted the bin folder Restarted Visual Studio Restarted IIS Restarted my Computer Added a simple Response.Write to ensure that the latest DLL is being used. It is. Made sure that Debug ASP.NET is checked in my project properties. It is. Made sure that all my projects are compiled in my build configuration. They are. But none of these help. I attach to w3wp, but my breakpoints never get hit. Any ideas?

• Creating a MSI patch (.msp) by hand?

  - by Jerry Chong

  Our team has recently been considering pushing out a minor registry fix to users to modify one particular problematic key. Pretty straightforward stuff, just needed to update 1 key/value inside the registry. So at the moment, we are using Wix to build .msi installers for the product. While looking into Wix's support for generating .msp patch files, it seems that the only way to create an .msp is a somewhat overcomplicated multi-step process to: Get a copy of the original MSI, and compile a new copy of the fixed MSI Write a new Wix file that points to both installers Compile the Wix file into a .wixobj with Candle to a .psp Run Torch/Pyro over before/after snapshots of the original installers and the .psp, or alternatively using MsiMsp.exe Now my question is, can't I simply describe the registry change into a Wix file and directly compile it into the .msp, without step 1 and 4 - which is a huge amount of effort for just a simple change?

• hadoop beginners question

  - by Omnipresent

  I've read some documentation about hadoop and seen the impressive results. I get the bigger picture but am finding it hard whether it would fit our setup. Question isnt programming related but I'm eager to get opinion of people who currently work with hadoop and how it would fit our setup: We use Oracle for backend Java (Struts2/Servlets/iBatis) for frontend Nightly we get data which needs to be summarized. this runs as a batch process (takes 5 hours) We are looking for a way to cut those 5 hours to a shorter time. Where would hadoop fit into this picture? Can we still continue to use Oracle even after hadoop?

• Can Response.Redirect work in a private void MVC 2 Function?

  - by user54197

  I have a private void function set for some validation. Should my validation fail, I would like to redirect to another ActionResult and kill the process for the ActionResult that was being used. Response.Redirect("controllerName") does not help. Any ideas? [Accept(HttpVerbs.Post)] public ActionResult NerdDinner(string Name) { testName(Name); ... Return RedirectToAction("ActionResultAAA"); } private void testName(string name) { if(name == null) { //Response.Redirect("ActionResultBBB"); } }

• Automating WebTrends analysis

  - by tridium

  Every week I access server logs processed by WebTrends (for about 7 profiles) and copy ad clickthrough and visitor information into Excel spreadsheets. A lot of it is just accessing certain sections and finding the right title and then copying the unique visitor information. I tried using WebTrends' built-in query tool but that is really poorly done (only uses a drag-and-drop system instead of text-based) and it has a maximum number of parameters and maximum length of queries to query with. As far as I know, the tools in WebTrends are not suitable to my purpose of automating the entire web metrics gathering process. I've gotten access to the raw server logs, but it seems redundant to parse that given that they are already being processed by WebTrends. To me it seems very scriptable, but how would I go about doing that? Is screen-scraping an option?

• Is there a way to convert a swf to an .abc file?

  - by Jeremy Ruppel

  I'm looking for a way, preferably a command-line utility, to pump out an .abc file for a compiled swf. I've looked into asc.jar, but so far it seems like it can only accept classes, not compiled swfs. Anybody know of a good way to do this? The end-goal of this process is to use Zwetan's RedTamarin project to run describeType on some specific classes inside a loaded swf, but there are complications with SecurityDomain preventing me from using Loader.loadBytes. If there's another good way to describe classes in the loaded swf via command-line, I'd be interested in that solution as well. Cheers, J

• Screen scrape a web page that uses javaScript and frames

  - by Mello

  Hi, I want to scrape data from www.marktplaats.nl . I want to analyze the scraped description, price, date and views in Excel/Access. I tried to scrape data with Ruby (nokogiri, scrapi) but nothing worked. (on other sites it worked well) The main problem is that for example selectorgadget and the add-on firebug (Firefox) don’t find any css I can use to scrape the page. On other sites I can extract the css with selectorgadget or firebug and use it with nokogiri or scrapi. Due to lack of experience it is difficult to identify the problem and therefore searching for a solution isn’t easy. Can you tell me where to start solving this problem and where I maybe can find more info about a similar scraping process? Thanks in advance!

• How to catch printf from a dll?

  - by Xarx

  I've got a C++ console application that uses a third-party dll (jvm.dll, indirectly) that uses printf to print various error messages (Java stacktrace). I need to catch these stacktraces to a string in order to process them further, or at least to see them printed on the console. The thing is that I see the stacktrace only when debugging my application in VisualStudio (VS 2010). When I run my application in the "normal way", i.e. from the command line, nothing is printed on the console. So VS is able to somehow interfere the java output and display it. I need to be able to do the same thing. I've already tried freopen(), but without success. Also, I've found this question on the same problem, but without a clear answer.

• Measuring execution time of a system call in C++

  - by jm1234567890

  I have found some code on measuring execution time here http://www.dreamincode.net/forums/index.php?showtopic=24685 However, it does not seem to work for system calls. I imagine this is because the execution jumps out of the current process. clock_t begin=clock(); system(something); clock_t end=clock(); cout<<"Execution time: "<<diffclock(end,begin)<<" s."<<endl; Then double diffclock(clock_t clock1,clock_t clock2) { double diffticks=clock1-clock2; double diffms=(diffticks)/(CLOCKS_PER_SEC); return diffms; } However this always returns 0 seconds... Is there another method that will work? Also, this is in Linux. Thanks!

• add schema to path in postgresql

  - by veilig

  I'm the process of moving applications over from all in the public schema to each having their own schema. for each application, I have a small script that will create the schema and then create the tables,functions,etc... to that schema. Is there anyway to automatically add a newly created schema to the search_path? Currently, the only way I see is to find the users current path SHOW search_path; and then add the new schema to it SET search_path to xxx,yyy,zzz; I would like some way to just say, append schema zzz to the users_search path. is this possible?

• Can only "agents" build and submit Applications to Apple?

  - by Martin

  I'm afraid I know the answer to this but I'll ask on the longshot chance that I'm wrong: I've been doing some freelance work creating an iPhone application for a company. They've created their own developer account and added me as an team member with "admin" rights. That seems to be the highest assignable rights (with the only higher level being "agent" and belonging only to whoever signed up for the account). Yet, I don't have an option under the provisioning portal to create a distribution certificate or profile. Is there any way to create these myself without having to ask my client for their primary login? They're not particulary tech savy so it would be difficult to walk them through the process to create the necessary certificates (and would require me giving them a certificate request from my computer, etc. etc.). But it seems like there should be some way to create a distribution build without "agent" rights, right? Could Apple seriously expect only one person from a company to do all the building and uploading of apps to the store?

• Recording Audio through RTMP/Rails

  - by Lowgain

  I am in the process of building a rails/flex application which requires audio to be recorded and then stored in our amazon s3 account. I have found no alternative to using some form of RTMP server for recording audio through flash, but our hosting environment will not allow us to install anything like FMS, Red5, etc. Is there any existing Ruby/Rails RTMP solution that will allow audio recording? If not, is it possible for Rails to at least intercept the RTMP stream and then I can hope to reference red5 or something for parsing the data (long shot, I know)? The other alternative I can think of is hosting a red5 server on another host and communicating with our rails app once the saving/uploading is done, which is not preferred. Am I going to have any luck here?

• NHibernate, the Parallel Framework, and SQL Server

  - by andy

  hey guys, we have a loop that: 1.Loops over several thousand xml files. Altogether we're parsing millions of "user" nodes. 2.In each iteration we parse a "user" xml, do custom deserialization 3.finally, in each iteration, we send our object to nhibernate for saving. We use: .SaveOrUpdateAndFlush(user); This is a lengthy process, and we thought it would be a perfect candidate for testing out the .NET 4.0 Parallel libraries. So we wrapped the loop in a: Parallel.ForEach(); After doing this, we start getting "random" Timeout Exceptions from SQL Server, and finally, after leaving it running all night, OutOfMemory unhandled exceptions. I haven't done deep debugging on this yet, but what do you guys think. Is this simply a limitation of SQL Server, or could it be our NHibernate setup, or what? cheers andy

• How can I call a module in a Perl one-liner?

  - by Zaid

  Say I have a data file that I want to process; I want to take the maximum value of each of the column and append it to the end of each line. INPUT: T1 T2 T3 35.82 34.67 31.68 32.20 34.52 33.59 37.41 38.64 37.56 OUTPUT: T1 T2 T3 35.82 34.67 31.68 35.82 32.20 34.52 33.59 34.52 37.41 38.64 37.56 38.64 I'm trying to implement this as a one-liner. So far, this is what I've come up with, although it complains that &main::max is undefined: perl -MList::Util -ani.bak -e "print qq(@F).q( ).max(@F).qq(\n)" file1.txt It seems that I haven't loaded the List::Util module. What's wrong? And is the header column an issue? perlrun doesn't have a decent example on how to do this (actually it does now, my documentation was a little out-of-date).

• Daemon with Clojure/JVM

  - by Isaac Copper

  I'd like to have a small (not doing too damn much) daemon running on a little server, watching a directory for new files being added to it (and any directories in the main one), and calling another Clojure program to deal with that new file. Ideally, each file would be added to a queue (a list represented by a ref in Clojure?) and the main process would take care of those files in the queue on a FIFO basis. My question is: is having a JVM up running this little program all the time too much a resource hog? And do you have any suggestions as to how go about doing this? Thank you very much!

• Explaining training method for AdaBoost algorithm

  - by konzti8

  Hi, I'm trying to understand the Haar feature method used for the training step in the AdaBoost algorithm. I don't understand the math that well so I'd appreciate more of a conceptual answer (as much as possible, anyway). Basically, what does it do? How do you choose positive and negative sets for what you want to select? Can it be generalized? What I mean by that is, can you choose it to find any kind of feature that you want no matter what the background is? So, for example, if I want to find some kind of circular blob - can I do that? I've also read that it is used on small patches for the images around the possible feature - does that mean you have to manually select that image patch or can it be automated to process the entire image? Is there matlab code for the training step? Thanks for any help...

• Cure for puzzle piece programming habits?

  - by Recursion

  Even though I went to a decent CS school, I was still taught with the mentality of programming with puzzle pieces. By puzzle pieces I mean, looking up code segments at each step of the development process and adding them together as needed. Eventually gathering all of the pieces and having a properly working program. So as an example, if in my program the next step is to tokenize a string, I go to google and search "how do I tokenize a string in language". All instead of critically thinking about its implementation. I personally don't think its a very good way to program and I always seem to forget everything that I have searched for. So how can I get out of this puzzle piece mode of programmer that I was taught.

• Separation of logic from presentation: HTTP variable names?

  - by Allan Jardine

  Hello all, This could probably be considered an academic question, rather than a real world one - but throwing it out to see if anyone has any great ideas! We all know that keeping the business logic of an application separate from the presentation is a good idea (I'm looking at web-apps atm), but there needs to be an understanding between the business logic for what HTTP variables to expect (and then process) and the variable names which are sent by the presentation layer. Is this simply a matter of telling the designer what variable names to use in a template? The template doesn't need to know what the variable names are (unless using them for JS/CSS selectors), so why should they be 'hardcoded' in there. Or should the business logic put the names into variables to be printed out? Another layer of complexity for the templates? Does anyone have any experience of this, or thoughts on how to deal with it? Thanks, Allan

• What ports does Advantage Database Server need?

  - by asherber

  I have an application which uses ADS and I am attempting to deploy it in a Windows network environment with a rather restrictive firewall. I am having a problem configuring firewall ports appropriately. ADS lives on \server, and it's listening on port 1234. When \client tries to connect to \server\tables, I get Error 6420 (Discovery process failed). When \client tries to connect to \server:1234\tables, I get error 6097, bad IP address specified in the connection path. \server is pingable from \client, and I can telnet to \server:1234. If I try to connect from a client machine inside the firewall, either connection path works fine. It seems there must be something else I need to open in the firewall. Any ideas? Thanks, Aaron.
