• Which would be better? Storing/access data in a local text file, or in a database?

  - by TerranRich

  Basically, I'm still working on a puzzle-related website (micro-site really), and I'm making a tool that lets you input a word pattern (e.g. "r??n") and get all the matching words (in this case: rain, rein, ruin, etc.). Should I store the words in local text files (such as words5.txt, which would have a return-delimited list of 5-letter words), or in a database (such as the table Words5, which would again store 5-letter words)? I'm looking at the problem in terms of data retrieval speeds and CPU server load. I could definitely try it both ways and record the times taken for several runs with both methods, but I'd rather hear it from people who might have had experience with this. Which method is generally better overall?

• .NET on Windows to Mono on Ubuntu

  - by Srikanth

  I am looking at a possibility to change my ASP.NET 2.0 application to the Mono framework. I have used the Mono Migration Analyzer tool and it does detect some P/Invoke and interop dependencies. For example: 1) We use Excel interops and on Linux we are looking to use StarOffice/OpenOffice instead. Is there an easy way of substituting Excel with StarOffice? (I know it sounds bizarre, but I just don't want to miss out in case anyone has done it already.) 2) LDAP authentication: What could be the best alternative in Ubuntu (or an other flavour of Linux)? 3) Is there an Ajax framework for Mono? Preferably with similar controls as Atlas? I hope I am not too ambitious here..

• Creating reference movies for iPhone on the fly

  - by Mad Oxyn

  We are working on an online mobile video app. The videos we want to play on mobile phones are being generated by a server, as there can be dynamic content in the server (based on user input). Now for iPhone we would like to play the video in the best possible resolution based on the connection speed at the time of downloading the movie. This can be done using reference movies. However, because our videos are being generated on the fly, we need to generate this reference movie on the fly as well. Is there a way to generate reference movies on the fly on a Linux server using some command line tool, PHP or Java? Or on a DOS server maybe? Any help will be much appreciated.

• Wrong intrepretation of some columns in ireport

  - by Purushotham

  Hi, I got a strange problem. I am using iReport 3.7.1 tool to create some reports. The Query Editor has one query. It shows all the data types of the fields in that query exactly same as the data types shown when I execute it using SQLYOG editor. The problem is here: One field data type is mismatched. I don't know the reason. SQLYOG says it is INTEGER whereas iReport Query Editor says its a long value. BTW The value that assigned to that filed is zero. Can anyone help ? I want to zero-in on this issue.

• Using R to open grib files

  - by robin girard

  I am using R to work with meteorological data. I proceed in two steps: 1- convert grib to netcdf using the commande line function ncl_convert2nc from ncar command language 2- use package ncdf in R to import the netcdf data. I have two problems: 1- I would like to do automatic treatment of many files within R. Can I call ncl_convert2nc within R ? 2- For some particular grib files, the convertion with ncar tool does not work. Is there other ways or trick (other than transcription into netcdf) to read grib files in R ?

• Refactoring PL/SQL triggers - extract procedures

  - by Juraj

  Hello, we have application where database contains large parts of business logic in triggers, with a update subsequently firing triggers on several other tables. I want to refactor the mess and wanted to start by extracting procedures from triggers, but can't find any reliable tool to do this. Using "Extract procedure" in both SQL Developer and Toad failed to properly handle :new and :old trigger variables. If you had similar problem with triggers, did you find a way around it? EDIT: Ideally, only columns that are referenced by extracted code would be sent as in/out parameters, like: Example of original code to be extracted from trigger: ..... if :new.col1 = some_var then :new.col1 := :old.col1 end if ..... would become : procedure proc(in old_col1 varchar2, in out new_col1 varchar2, some_var varchar2) is begin if new_col1 = some_var then new_col1 := old_col1 end if; end; ...... proc(:old.col1,:new.col1, some_var);

• Suggestions for a good IDE for DB2

  - by ken

  Hi all, I know, I know... it's a horrible fate but I am forced to work in an environment with DB2 on the back end. OK just kidding but the truth is I do like MSSQL's data studio a lot, and well IBM's tool is sorda crummy in my opinion... I was using the free version of Toad but I just got a new 64bit machine which is nice and all but there isn't a free version of Toad that I can find for win7 64. Does anyone have any suggestions for a good IDE to use with DB2? Being a developer I really just do a lot of looking at the DB structure and querying to see what I get back and how I want to get things back etc... Thanks for any advice!

• Unrecognized option: -o Could not create the Java virtual machine.

  - by Kerubu

  I've got an unusual build error when using Buildroot to create an image for my Phidget SBC. It's unusual because it occurs ONLY on my development laptop and NOT on my general use laptop even though I am using EXACTLY the same Builroot environment as published by Phidgets themselves. When I try to create my Buildroot image I get the following error when it attempts to compile GNU classpath: Making all in tools make[2]: Entering directory `/home/xxxx/buildroot_phidgetsbc/buildroot-phidgetsbc_1.0.4.20111028/output/build/classpath-0.98/tools' /bin/mkdir -p classes asm /bin/mkdir -p ../tools/generated/gnu/classpath/tools/gjdoc/expr java -classpath antlr.Tool -o ../tools/generated/gnu/classpath/tools/gjdoc/expr/ \ ./gnu/classpath/tools/gjdoc/expr/java-expression.g Unrecognized option: -o Could not create the Java virtual machine. make[2]: *** [tools.zip] Error 1 The only difference I can possibly thing of is the different Linux (Ubuntu) versions I am using on each laptop. Also I cannot find a -o option documented for Java and don't understand why it works on one laptop but not the other. Any suggestions would be helpful.

• Are there any ASP.NET MVC Real Time View Editors?

  - by BenMaddox

  I'm looking for a tool and I'm not even sure of the proper name. Please be patient with me as I explain. I'm doing a lot of html/mvc 2 work. Using the standard MVC 2 view engine, I would like to have an editor that shows real time changes in the browser. If I re-arrange div elements containing standard HTML and some server side components, I would like the browser to update without a manual refresh. Are there any tools that are currently available that would meet that requirement?

• Are there cheat sheets for misc source code management tools?

  - by Alex_coder

  I'm looking for something similar to Pacman Rosetta, which explains how to achieve similar tasks using different source code management tools. Sometimes docs for a certain SCM contain examples comparing that particular SCM to a couple of others. But I'm looking for a central place that contains maximum available information. Example: one uses bzr and knows that 'bzr pull' syncs a local repo by fetching new content from a remote repo. One want to know how to do that with git. One finds the git command, he knows the keyword. Since the keyword is known, one can proceed straight to git docs, he knows what to read about, he doesn't have to waste time by searching the git docs. I understand this might be not the only way people use to learn a new SCM tool. If you use other approaches, please do tell.

• WPF, convert Path.DataProperty to Segment objects

  - by user275587

  I was wondering if there was a tool to convert a path data like "M 0 0 l 10 10" to it's equivalent line/curve segment code. Currently I'm using: string pathXaml = "<Path xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\" Data=\"M 0 0 l 10 10\"/>"; Path path = (Path)System.Windows.Markup.XamlReader.Load(pathXaml); It appears to me that calling XamlParser is much slower than explicitly creating the line segments. However converting a lot of paths by hand is very tedious.

• Loading large amounts of data to an Oracle SQL Database

  - by James

  Hey all, I was wondering if anyone had any experience with what I am about to embark on. I have several csv files which are all around a GB or so in size and I need to load them into a an oracle database. While most of my work after loading will be read-only I will need to load updates from time to time. Basically I just need a good tool for loading several rows of data at a time up to my db. Here is what I have found so far: I could use SQL Loader t do a lot of the work I could use Bulk-Insert commands Some sort of batch insert. Using prepared statement somehow might be a good idea. I guess I was wondering what everyone thinks is the fastest way to get this insert done. Any tips?

• Documentation for Qt documentation comments? Qt + Doxygen?

  - by Jake Petroules

  Where can I find documentation for Qt documentation comments? I'm referring to how Qt uses a specific style for documentation comments, like so: /*! \class MyClassName \brief The MyClassName class is used as an example on Stack Overflow. This class serves a few functions, the most important being: \list \i So people can understand my question. \i So people can have a few laughs at the comedy in my example. \endlist */ ...you get the picture. So where can I find information about all the switches, like \class, \list, \brief, etc. Also, what tool(s) do I use to generate documentation files from these comments in my source files? Does Doxygen support this syntax?

• Number of times a file (e.g., PDF) was accessed on a server

  - by Ivan

  I have a small website with several PDFs free for download. I use StatCounter to observe the number of page loads. It also shows me the number of my PDF downloads, but it considers only those downloads where a user clicks on the link from my website. But what's with the "external" access to the PDFs (e.g., directly from Google search)? How I can count those? Is there any possibility to use a tool such as StatCounter? Thanks.

• Tools for displaying text, powerpoint style, in linux

  - by Will Mc

  I have a problem where I need a way to display a repeating series of "images" on a computer monitor. Specifically, given a series of text files, I'd like a way to display the contents of said files on a screen in a way much like a powerpoint would. My current thoughts are to find some tool that will take in a text file of some format, and then output an image which contains the text from the file. Then I'd put it in a directory and have some Slideshow program continuously go between the images in that directory. It's a very hacky solution, obviously. So, does anyone know of tools that would do such a thing? Or is there a better way to do this? I've looked into the library libgd2, but it doesn't seem to support text-wrapping for images, which is something I'd need. Thanks!

• Does any Version Control System like SVN, Git, or Mercurial let you "keep latest version" but not th

  - by Jian Lin

  In our project files, if there are binary files, such as .doc, .xls, .jpg, and we choose to not keep their past revisions (just keeping a latest version is ok), is there a way to tell SVN, Git, or Mercurial or some other tool to skip the revisions for these files or for a particular folder? Say, there is a 4MB .doc file that I need to check in hundred of times, but I don't really care so much about its past versions. So if the system keeps 100 revisions of it, that's already 400MB... checking in 300 times means 1.2GB for 1 file and that's not good. Only the latest version is good so that everybody can sync to it.

• How do I get the response time from a jQuery ajax call?

  - by Dumpen

  So I am working on tool that can show long a request to a page is taking. I am doing this by using jQuery Ajax (http://api.jquery.com/jQuery.ajax/) and I want to figure out the best way to get the response time. I found a thread (http://forum.jquery.com/topic/jquery-get-time-of-ajax-post) which describes using the "Date" in JavaScript, but is this method really reliable? An example of my code could be this below $.ajax({ type: "POST", url: "some.php", }).done(function () { // Here I want to get the how long it took to load some.php and use it further });

• sql select with php variable

  - by user1572526

  I'm trying to print out a html-table from db-table 'dimensions'. I only want dimensions from the selected pipetype which I get from a dropdownbox. For now I just put in "Steel" manually. Steel has pipe_id = 2 in db-table 'pipes'. I've run the first query in my db-tool and it returns 2 so there's nothing wrong there. The second query returns nothing. But when I manually set $wq = 2 (which I comment out below) it prints out the html-table perfectly. What am I doing wrong here? $wq="SELECT pipe_id FROM pipes WHERE title_en = 'Steel'"; //$wq = '2'; $sql="SELECT * FROM dimensions WHERE pipe_id = '".$wq."'";

• (VB or C#) Run app in system tray and listen to keyboard input even when the app is not in focus

  - by Avinash Sonee

  I want to make an app which on loading sits in the system tray and even after I open another program (say notepad or vlc or anything) i.e. even when the app is not in focus and if I press "G" on my keyboard, the tray icon should show a tool tip - "key G is pressed". I have tried several codes but nothing works when the app goes out of focus. I can use Register Hot Key (http://msdn.microsoft.com/en-us/library/ms646309(VS.85).aspx) but it needs a modifier also (like Ctrl or Alt etc. along with my key G). So, is there any way I can achieve this? something which many tray icons do like antivirus apps, etc. and I do not want to use AutoHotkey application. I want to build one but need some help. Thanks!

• Looping over some selected values in a stored procedure

  - by macca1

  I'm trying to modify a stored procedure hooked into an ORM tool. I want to add a few more rows based on a loop of some distinct values in a column. Here's the current SP: SELECT GRP = STAT_CD, CODE = REASN_CD FROM dbo.STATUS_TABLE WITH (NOLOCK) Order by STAT_CD, SRT_ORDR For each distinct STAT_CD, I'd also like to insert a REASN_CD of "--" here in the SP. However I'd like to do it before the order by so I can give them negative sort orders so they come in at the top of the list. I'm getting tripped up on how to implement this. Does anyone know how to do this for each unique STAT_CD?

• Are C/C++/ObjC/JS Apple's only allowed langauges for iPhone development?

  - by fbrereto

  According to this post on Daring Fireball a new iPhone SDK Agreement release in conjunction with the iPhone OS 4.0 announcement today specifically bans any iPhone application not implemented in C, C++ Objective-C or JavaScript. The clear impact here is to the wide array of programs written in languages other than those. Is that your reading of the clause in the new agreement as well? Update: Here is the clause as printed on Daring Fireball: 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

• javascript not working on localhost

  - by Adam McMahon

  Ok so I'm lost here, frustrated and pulling my hair and out. Plus probably about to be fired or take a pay cut. I moved Files from a development server to my local machine. The files are consistent (used diff tool), all the dependencies are there. It works for the most part. The problem is that the some of the javascript (not all) is just not working. We're using jquery and a lot of plugins for it. I've checked with the web developer plugin in firefox and all the js files are loading. I cleared the cache in both firefox and chrome multiple times to no avail. The development server is a windows server running wamp. My local machine is running ubuntu. Somebody tell me what I missed.

• How does SWTBOT run a custom eclipse based application? I don't know how to specify my target application

  - by jlisam13

  I have an eclipse based application. I have heard of swtbot however I am having a hard time understanding how exactly does this tool run my application and how would I specify that. This eclipse based application has an executable and various configuration/plugin/features files. I have done the tutorials about swtbot and I have successfully completed them but they all just create a template application to test on. Is this even possible? If not do you guys have any alternatives for UI automation testing on eclipse based apps? Thanks.

• Deactivate any calls to Log before publishing: are there tools to do this?

  - by Nicolas Raoul

  According to Google, I must "Deactivate any calls to Log methods in the source code" before publishing my Android app (section 4 of the publication checklist). My open-source project is large and it is a pain to do it manually every time I release. Additionally, removing a Log line is potentially tricky, for instance: if(condition) Log.d(LOG_TAG, "Something"); data.load(); data.show(); If I comment the Log line, then the condition applies to the next line, and chances are load() is not called. Are such situations rare enough that I can decide it should exist? This is on the official checklist, so I guess many people do this on a regular basis. So, is there a tool that removes all Log lines? Preferably one that is not tricked by code like the above.
