  • Cannot change font size /type in plots

    - by Sameet Nabar
    I recently had to re-install my operating system (Ubuntu). The only thing I did differently is that I installed Matlab on a separate partition, not the main Ubuntu partition. After re-installing, the fonts in my plots are no longer configurable. For example, if I ask the title font to be bold, it doesn't happen. I ran the sample code below on my computer and then on my colleague's computer and the 2 results are attached. This cannot be a problem with the code; rather in the settings of Matlab. Could somebody please tell me what settings I need to change? Thanks in advance for your help. Regards, Sameet. x1=-pi:.1:pi; x2=-pi:pi/10:pi; y1=sin(x1); y2=tan(sin(x2)) - sin(tan(x2)); [AX,H1,H2]=plotyy(x1,y1,x2,y2); xlabel ('Time (hh:mm)'); ylabel (AX(1), 'Plot1'); ylabel (AX(2), 'Plot2'); axes(AX(2)) set(H1,'linestyle','none','marker','.'); set(H2,'linestyle','none','marker','.'); title('Plot Title','FontWeight','bold'); set(gcf, 'Visible', 'off'); [legh, objh] = legend([H1 H2],'Plot1', 'Plot2','location','Best'); set(legend,'FontSize',8); print -dpng Trial.png; Bad image: http://imageshack.us/photo/my-images/708/trial1u.png/ Good image: http://imageshack.us/photo/my-images/87/trial2.png/

  • How can I keep curl output out of mail from my cronjob?

    - by Russell C.
    I have written a Perl script that runs as a daily crontab job that uploads files to Amazon S3 via CURL. I want the output of the cron job emailed to me which works fine but I don't want that email to include messages related to the CURL upload (only those message my script is outputting). Here are the CURL related messages I'm seeing in the daily email right now: % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 230M 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 0 230M 0 0 0 544k 0 1519k 0:02:35 --:--:-- 0:02:35 1807k 0 230M 0 0 0 1744k 0 1286k 0:03:03 0:00:01 0:03:02 1342k 1 230M 0 0 1 2880k 0 1219k 0:03:13 0:00:02 0:03:11 1250k 1 230M 0 0 1 4016k 0 1198k 0:03:17 0:00:03 0:03:14 1218k 2 230M 0 0 2 5168k 0 1186k 0:03:19 0:00:04 0:03:15 1202k 2 230M 0 0 2 6336k 0 1181k 0:03:19 0:00:05 0:03:14 1157k 3 230M 0 0 3 7488k 0 1177k 0:03:20 0:00:06 0:03:14 1147k 3 230M 0 0 3 8592k 0 1167k 0:03:22 0:00:07 0:03:15 1142k 4 230M 0 0 4 9744k 0 1166k 0:03:22 0:00:08 0:03:14 1145k 4 230M 0 0 4 10.6M 0 1163k 0:03:23 0:00:09 0:03:14 1142k 5 230M 0 0 5 11.7M 0 1161k 0:03:23 0:00:10 0:03:13 1140k 5 230M 0 0 5 12.8M 0 1158k 0:03:23 0:00:11 0:03:12 1133k 6 230M 0 0 6 13.9M 0 1155k 0:03:24 0:00:12 0:03:12 1138k 6 230M 0 0 6 15.0M 0 1155k 0:03:24 0:00:13 0:03:11 1138k 7 230M 0 0 7 16.1M 0 1152k 0:03:25 0:00:14 0:03:11 1131k 7 230M 0 0 7 17.2M 0 1152k 0:03:25 0:00:15 0:03:10 1132k 7 230M 0 0 7 18.4M 0 1152k 0:03:24 0:00:16 0:03:08 1140k I am using a simple Perl system() call to invoke CURL.

  • Programmatic Text Wrapping in TextView

    - by Andrew
    I'm working on a custom widget for my application to replicate the look of a Preference button for layouts. The issue is the 'summary' text wont wrap when it hits the right wall of the view. One of the goals I'm trying to keep is that this widget is completely made from java with no xml attributes. here's what the widget looks like at the moment: http://dl.dropbox.com/u/56017670/Screenshot_2012-09-05-17-22-45.png notice that the middle two don't wrap the text but the text obviously runs right off the edge of the widget below is the code I'm using to create the text view. public void setSummary(String summary) { if (!TextUtils.isEmpty(summary)) { if (mSummaryView == null) { mSummaryView = new TextView(mContext); mSummaryView.setTextSize(14); mSummaryView.setTextColor(mContext.getResources().getColor( android.R.color.tertiary_text_dark)); addView(mSummaryView); } mSummaryView.setText(summary); mSummaryView.setVisibility(View.VISIBLE); } else { if (mSummaryView != null) { mSummaryView.setVisibility(View.GONE); } } mSummaryText = summary; } and here is the code I'm using to layout mSummaryView mSummaryView.layout( mPreferencePadding + mIconWidth, centerVertical + (mCombinedTextHeight / 2) - mSummaryHeight, width - mPreferencePadding, centerVertical + (mCombinedTextHeight / 2)); I've tried to add mSummaryView.setSingleLine(false); along with quite a few other tricks but they all ended in the same way.

  • parsing urls from windows batch file

    - by modest
    I have a text file (myurls.txt) whose contents are a list of URLs as follow: Slides_1: http://linux.koolsolutions.com/svn/ProjectA/tags/REL-1.0 Exercise_1: http://linux.koolsolutions.com/svn/ProjectA/tags/REL-1.0 Slides_2: http://linux.koolsolutions.com/svn/oldproject/ProjectB/tags/REL-2.0 Exercise_2: http://linux.koolsolutions.com/svn/ProjectB/tags/REL-1.0 Exercise_3: http://linux.koolsolutions.com/svn/BlueBook/ProjectA/tags/REL-1.0 Now I want to parse this text file in a for loop such that after each iteration (for e.g. take the first url from the above file) I have the following information into different variables: %i% = REL-1.0 %j% = http://linux.koolsolutions.com/svn/ProjectA %k% = http://linux.koolsolutions.com/svn/ProjectA/tags/REL-1.0 After some experiment I have the following code but it only works (kind of) if the URLs have same number of slashes: @echo off set FILE=myurls.txt FOR /F "tokens=2-9 delims=/ " %%i in (%FILE%) do ( @REM <do something with variables i, j and k.> ) I am fine with other solutions like for e.g. using Windows Script Host/VBS script as long as it can run with a default Windows XP/7 installation. In other words, I know I can use awk, grep, sed, python, etc. for Windows and get the job done but I don't want the users to have to install anything besides a standard windows installation.

  • DOM manipulation

    - by bluedaniel
    Hello everyone, Im trying to use the DOM in PHP to do a pretty specific job and Ive got no luck so far, the objective is to take a string of HTML from a Wordpress blog post (from the DB, this is a wordpress plugin). And then out of that HTML replace <div id="do_not_edit">old content</div>" with <div id="do_not_edit">new content</div>" in its place. Saving anything above and below that div in its structure. Then save the HTML back into the DB, should be simple really, I have read that a regex wouldnt be the right way to go here so Ive turned to the DOM instead. The problem is I just cant get it to work, cant extract the div or anything. Help me!! UPDATE The HTML coming out of the wordpress table looks like: Congratulations on finding us here on the world wide web, we are on a mission to create a website that will show off your culinary skills better than any other website does. <div id="do_not_edit">blah blah</div> We want this website to be fun and easy to use, we strive for simple elegance and incredible functionality.We aim to provide a 'complete package'. By this we want to create a website where people can meet, share ideas and help each other out. After several different (incorrect) workings all Ive got below is: $content = ($wpdb->get_var( "SELECT `post_content` FROM $wpdb->posts WHERE ID = {$article[post_id]}" )); $doc = new DOMDocument(); $doc->validateOnParse = true; $doc->loadHTMLFile($content); $element = $doc->getElementById('do_not_edit'); echo $element;

  • How to set logging level for JDBCDriverLogging

    - by Scott
    I am trying to change the logging level to stop showing millions of this: <May 26, 2010 10:26:02 AM EDT> <Debug> <JDBCDriverLogging> <000000> <2336: 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 | |> I have tried adding this to my java line: -Djava.util.logging.config.file=/foo/bar/logging.properties With this as my logging.properties file: handlers = java.util.logging.ConsoleHandler .level = OFF java.util.logging.ConsoleHandler.level = INFO No luck. I have tried this: Logger logger = Logger.getLogger("com.microsoft.sqlserver.jdbc"); Handler handler = new ConsoleHandler(); handler.setLevel(Level.INFO); logger.addHandler(handler); logger.setLevel(Level.INFO); logger.setUseParentHandlers(false); No luck. I have searched around and all ideas center around one of these two options, so I must be doing something else wrong I am using jtds-1.2.2.jar. Thanks for any suggestions.

  • CodeIgniter - Image Validation & Thumbnailing

    - by Sebhael
    I'm currently trying to create a function that validates and creates thumbnails for images on upload - but I'm quite lost on what I'm doing. I'm assuming I'm off on my terminology so I'm not really getting any search results to help point me in the right direction. My playground is a form with 6 upload fields that are required. One of these fields is for a simple 32x32 icon image, another a portrait orientation (most likely) photo, and then 4 standard desktop screenshots -- and I'm using CodeIgniter as my framework. I would like to create a function that validates/thumbnails images, and only have to call it on the validation if at all possible. I know I can achieve this per-image, since the documentation for CI is quite through on this - but to reduce redundancy I'm looking for the better option. Outside of that, I don't even actually understand in full how to manipulate images unless it's just $this-input-post('field') - then calling all functions onto this? I don't know, I'm confused and posting on the actual CI forums has yielded me nothing - so all I'm really looking for is a point in the right direction to understanding what I'm trying to achieve here. This also all might not make any sense, I know it doesn't to me - but I can explain more if needed. Thanks in advance.

  • Invoking different methods on threads

    - by Kraken
    I have a main process main. It creates 10 threads (say) and then what i want to do is the following: while(required){ Thread t= new Thread(new ClassImplementingRunnable()); t.start(); counter++; } Now i have the list of these threads, and for each thread i want to do a set of process, same for all, hence i put that implementation in the run method of ClassImplementingRunnable. Now after the threads have done their execution, i wan to wait for all of them to stop, and then evoke them again, but this time i want to do them serially not in parallel. for this I join each thread, to wait for them to finish execution but after that i am not sure how to evoke them again and run that piece of code serially. Can i do something like for(each thread){ t.reevoke(); //how can i do that. t.doThis(); // Also where does `dothis()` go, given that my ClassImplementingRunnable is an inner class. } Also, i want to use the same thread, i.e. i want the to continue from where they left off, but in a serial manner. I am not sure how to go about the last piece of pseudo code. Kindly help. Working with with java.

  • better understanding of getline() and cin

    - by numerical25
    Trying to get some basic understanding of console functionalities. I am having issues so consider the following... #include "stdafx.h" #include<iostream> #include<conio.h> using namespace std; /* This is a template Project */ void MultiplicationTable(int x); int main() { int value = 0; printf("Please enter any number \n\n"); getline(cin, value); MultiplicationTable(value); getchar(); return 0; } I actually based this off code from http://www.cplusplus.com/doc/tutorial/basic_io/ . My IDE is not recognizing getline() so of course when I compile the application. I get an error 'getline': identifier not found Now take a look at this code #include "stdafx.h" #include<iostream> #include<conio.h> using namespace std; /* This is a template Project */ void MultiplicationTable(int x); int main() { int value = 0; printf("Please enter any number \n\n"); cin>>value; MultiplicationTable(value); getchar(); return 0; } When I execute this line of code the console window opens and immediately closes. I think I a missing something about cin. I do know that it delimits spaces but I don't know what else. what should I use for input to make my life easier.

  • JAR files, don't they just bloat and slow Java down?

    - by Josamoto
    Okay, the question might seem dumb, but I'm asking it anyways. After struggling for hours to get a Spring + BlazeDS project up and running, I discovered that I was having problems with my project as a result of not including the right dependencies for Spring etc. There were .jars missing from my WEB-INF/lib folder, yes, silly me. After a while, I managed to get all the .jar files where they belong, and it comes at a whopping 12.5MB at that, and there's more than 30 of them! Which concerns me, but it probably and hopefully shouldn't be concerned. How does Java operate in terms of these JAR files, they do take up quite a bit of hard drive space, taking into account that it's compressed and compiled source code. So that can really quickly populate a lot of RAM and in an instant. My questions are: Does Java load an entire .jar file into memory when say for instance a class in that .jar is instantiated? What about stuff that's in the .jar that never gets used. Do .jars get cached somehow, for optimized application performance? When a single .jar is loaded, I understand that the thing sits in memory and is available across multiple HTTP requests (i.e. for the lifetime of the server instance running), unlike PHP where objects are created on the fly with each request, is this assumption correct? When using Spring, I'm thinking, I had to include all those fiddly .jars, wouldn't I just be better off just using native Java, with say at least and ORM solution like Hibernate? So far, Spring just took extra time configuring, extra hard drive space, extra memory, cpu consumption, so I'm concerned that the framework is going to cost too much application performance just to get for example, IoC implemented with my BlazeDS server. There still has to come ORM, a unit testing framework and bits and pieces here and there. It's just so easy to bloat up a project quickly and irresponsibly easily. Where do I draw the line?

  • I'm annoyed with asp .net mvc action links? Is there something better in MVC3?

    - by Jonathon Kresner
    After almost 3 years with mvc I'm scratching my head. Is it just me, or does the way we specify links in asp .net mvc suck? @Html.ActionLink("Log Off", "LogOff", "Account") In the previews for mvc 1 we had the funky generic action links which gave us intellisense and compile checking, which I LOVED. I know they removed them because of performance issues and because you could not actually guarantee that the route would resolve all the time... However the default way of doing it just doesn't make me feel safe enough in a big application. I've also used T4Mvc with MVC2, to be honest, I didn't really like it. It's not part of the Mvc framework and frustrating to develop with especially with source control in big teams and continuous integration builds. I guess I could also import Mvc Futures and keep using the generic types (it's probably what I'll do). I'm just about to start a very big project and was wondering what other people are thinking? Is anyone else annoyed with the options or has a new solution? It seems like ActionLinks are the most basic & frequently used feature. Shouldn't there be a good out of the box solution, we're just about to hit revision 3 of this framework.

  • File IO with Streams - Best Memory Buffer Size

    - by AJ
    I am writing a small IO library to assist with a larger (hobby) project. A part of this library performs various functions on a file, which is read / written via the FileStream object. On each StreamReader.Read(...) pass, I fire off an event which will be used in the main app to display progress information. The processing that goes on in the loop is vaired, but is not too time consuming (it could just be a simple file copy, for example, or may involve encryption...). My main question is: What is the best memory buffer size to use? Thinking about physical disk layouts, I could pick 2k, which would cover a CD sector size and is a nice multiple of a 512 byte hard disk sector. Higher up the abstraction tree, you could go for a larger buffer which could read an entire FAT cluster at a time. I realise with today's PC's, I could go for a more memory hungry option (a couple of MiB, for example), but then I increase the time between UI updates and the user perceives a less responsive app. As an aside, I'm eventually hoping to provide a similar interface to files hosted on FTP / HTTP servers (over a local network / fastish DSL). What would be the best memory buffer size for those (again, a "best-case" tradeoff between perceived responsiveness vs. performance).

  • Output columns not in destination table?

    - by lance
    SUMMARY: I need to use an OUTPUT clause on an INSERT statement to return columns which don't exist on the table into which I'm inserting. If I can avoid it, I don't want to add columns to the table to which I'm inserting. DETAILS: My FinishedDocument table has only one column. This is the table into which I'm inserting. FinishedDocument -- DocumentID My Document table has two columns. This is the table from which I need to return data. Document -- DocumentID -- Description The following inserts one row into FinishedDocument. Its OUTPUT clause returns the DocumentID which was inserted. This works, but it doesn't give me the Description of the inserted document. INSERT INTO FinishedDocument OUTPUT INSERTED.DocumentID SELECT DocumentID FROM Document WHERE DocumentID = @DocumentID I need to return from the Document table both the DocumentID and the Description of the matching document from the INSERT. What syntax do I need to pull this off? I'm thinking it's possible only with the one INSERT statement, by tweaking the OUTPUT clause (in a way I clearly don't understand)? Is there a smarter way that doesn't resemble the path I'm going down here? EDIT: SQL Server 2005

  • What's the best approach for getting into VS2010, C# 4, and WPF if my background is in C++/MFC

    - by Canacourse
    All my past programming experience has been in C++ on VS2003/8, Mostly service based and completely self taught. 2 Years ago I had to create my first real GUI app and (Foolishly) choose MFC. I got the app working but it took a long time & was a bit of a nightmare to learn MCF (and its many shortcomings) but I ended up with a reliable workable app which was difficult to change or extend. Again I have to create another GUI app more complex than the first and again this will be created from scratch and will only ever be used on windows. I had put off learning C# for a long time but not wishing to re-visit MFC have decided that the new application with be birthed in VS2010 and WPF 4 will be the midwife. Trying to avoid the several expensive (Time wise) mistakes I made previously. Im looking for for good books/tutorials on the current versions of C# 4 & WPF 4 and also general advice on the best approach. The application will do several things one of them would persisting info in a SQL DB. So Im thinking LINQ for that? Please chip in...

  • Keeping track of dependency revisions

    - by Samaursa
    I have a project with several dependencies that are in various repositories. Each time I commit changes to my project, I make sure I write the revision numbers of all the dependent repositories so that in the event I ever have to come back to this revision (let's call it 5), I can immediately know which revisions of the dependent repositories revision 5 is guaranteed to work with, update the dependencies to the specified revisions, compile and run the project. So for example if I have: Dep1 @ Revisions 10 Dep2 @ Revisions 20 Dep3 @ Revisions 10 Proj @ Revisions 35 And let's say that when Proj was on revision 17, the Dep1 revision was 5, Dep2 revision was 13 and Dep3 revision was 3. So in my SVN logs, I recorded something like this: !! Works with Dep1 Rev 5, Dep2 Rev 13, Dep3 Rev 3 To me this seems primitive and makes me believe that there is a better way to do it. Now in one of my other questions, Ivy Dependency Manager has been recommended. I have not looked at it in detail yet (seems complicated and yet another thing I must learn). To me it seems like the log of SVN (and Mercurial etc.) could have been split into Log and Dependencies (if any) where the latter could be switched off if there were no dependencies (unless of course I am unaware of an easier/better solution). This would allow for a cleaner log that maybe even warned at each new commit to check the previously defined dependencies again and make sure they have not changed. So, I was wondering how everyone manages this situations and if you have any tips, techniques, programs, suggestions that you can offer. Thank you.

  • Attempting to calculate width of Map Overlays on the fly

    - by Bloudermilk
    Hey all- I am working on an Android app that utilizes the Google Maps API MapView, MapController, MapActivity, and ItemizedOverlay. I am basically trying to recreate certain functionalities of the Maps app (damn Google for not providing speech bubbles—for lack of a better name—for items!), particularly those speech bubbles. I have an invisible XML structure for the speech bubble in the XML layout file containing my MapView. The first time I show a speech bubble I grab that XML and remove it from it's current parent, applying some ItemizedOverlay.LayoutParams to it, and add it to the MapView as an Overlay. I position it above the item that was selected, fill it with the proper text, then set it to visible. This all works great. The goal here, though, is to also automatically animate the map to reveal any parts of a speech bubble that may be off-screen when it opens. So I'm trying popup.getWidth() (popup is the instance of my LinearLayout that is the speech bubble) after I do all the manipulation to the bubble, even after I display it to the user. Problem is, popup.getWidth() is returning me the width of the previously displayed popup, not the currently displayed one. I can't figure out why this would be happening if I'm fetching the width after I set it to visible with its new dimensions (which, by the way, are relative when I'm setting them with LayoutParams: fill_content for both width and height).. I have even tried forcing both the MapView and the "popup" to invalidate() before trying to fetch the width. Any ideas why this may be happening? How can I force the View to settle into its new dimensions before trying to fetch them? Thanks! Nick

  • jQuery hide all table rows which contain a hidden field matching a value

    - by Famous Nerd
    Though I don't doubt this has been answered I cannot find a great match for my question. I have a table for which I'd like to filter rows based on whether or not they contain a hidden field matching a value. I understand that the technique tends to be "show all rows", "filter the set", "show/hide that filtered set" I have the following jquery but I'm aweful with filter and my filtered set seems to always contain no elements. my table is the usual <table> <tr><td>header></td><td>&nbsp;</tr> <tr> <td>a visible cell</td><td><input type='hidden' id='big-asp.net-id' value='what-im-filtering-on' /> </td> </tr> </table> My goal is to be able to match on tr who's descendent contains a hidden input containing either true or false. this is how I've tried the selector (variations of this) and I'm not even testing for the value yet. function OnFilterChanged(e){ //debugger; var checkedVal = $("#filters input[type='radio']:checked").val(); var allRows = $("#match-grid-container .tabular-data tr"); if(checkedVal=="all"){ allRows.show(); } else if(checkedVal=="matched"){ allRows.show(); allRows.filter(function(){$(this).find("input[type='hidden'][id~='IsAutoMatchHiddenField']")}).hide(); } else if(checkedVal=="unmatched"){ } } Am I way off with the filter? is the $(this) required in the filter so that i can do the descendant searching? Thanks kindly

  • SQL with HAVING and temp table not working in Rails

    - by chrisrbailey
    I can't get the following SQL query to work quite right in Rails. It runs, but it fails to do the "HAVING row_number = 1" part, so I'm getting all the records, instead of just the first record from each group. A quick description of the query: it is finding hotel deals with various criteria, and in particular, priortizing them being paid, and then picking the one with the highest dealrank. So, if there are paid deal(s), it'll take the highest one of those (by dealrank) first, if no paid deals, it takes the highest dealrank unpaid deal for each hotel. Using MAX(dealrank) or something similar does not work as a way to pick off the first row of each hotel group, which is why I have the enclosing temptable and the creation of the row_number column. Here's the query: SELECT *, @num := if(@hid = hotel_id, @num + 1, 1) as row_number, @hid := hotel_id as dummy FROM ( SELECT hotel_deals.*, affiliates.cpc, (CASE when affiliates.cpc 0 then 1 else 0 end) AS paid FROM hotel_deals INNER JOIN hotels ON hotels.id = hotel_deals.hotel_id LEFT OUTER JOIN affiliates ON affiliates.id = hotel_deals.affiliate_id WHERE ((hotel_deals.percent_savings = 0) AND (hotel_deals.booking_deadline = ?)) GROUP BY hotel_deals.hotel_id, paid DESC, hotel_deals.dealrank ASC) temptable HAVING row_number = 1 I'm currently using Rails' find_by_sql to do this, although I've also tried putting it into a regular find using the :select, :from, and :having parts (but :having won't get used unless you have a :group as well). If there is a different way to write this query, that'd be good to know too. I am using Rails 2.3.5, MySQL 5.0.x.

  • How To perform a SQL Query to DataTable Operation That Can Be Cancelled

    - by David W
    I tried to make the title as specific as possible. Basically what I have running inside a backgroundworker thread now is some code that looks like: SqlConnection conn = new SqlConnection(connstring); SqlCommand cmd = new SqlCommand(query, conn); conn.Open(); SqlDataAdapter sda = new SqlDataAdapter(cmd); sda.Fill(Results); conn.Close(); sda.Dispose(); Where query is a string representing a large, time consuming query, and conn is the connection object. My problem now is I need a stop button. I've come to realize killing the backgroundworker would be worthless because I still want to keep what results are left over after the query is canceled. Plus it wouldn't be able to check the canceled state until after the query. What I've come up with so far: I've been trying to conceptualize how to handle this efficiently without taking too big of a performance hit. My idea was to use a SqlDataReader to read the data from the query piece at a time so that I had a "loop" to check a flag I could set from the GUI via a button. The problem is as far as I know I can't use the Load() method of a datatable and still be able to cancel the sqlcommand. If I'm wrong please let me know because that would make cancelling slightly easier. In light of what I discovered I came to the realization I may only be able to cancel the sqlcommand mid-query if I did something like the below (pseudo-code): while(reader.Read()) { //check flag status //if it is set to 'kill' fire off the kill thread //otherwise populate the datatable with what was read } However, it would seem to me this would be highly ineffective and possibly costly. Is this the only way to kill a sqlcommand in progress that absolutely needs to be in a datatable? Any help would be appreciated!

  • How Best to Replace Ugly Queries and Dynamic PL/SQL with C#?

    - by Mike
    Hi, I write a lot of one-off Oracle SQL queries (in Toad), and sometimes they can get complex, involving lots of unions, joins, and subqueries, and sometimes requiring dynamic SQL. That is, sometimes SQL queries require set based processing along with significant procedural processing. This is what PL/SQL is custom made for, but as a language it does not begin to compare to C#. Now and then I convert a PL/SQL procedure to C#, and am always amazed at how much cleaner and easier to both read and write the C# version is. The C# program might for example construct a SQL query string piece by piece and/or run several queries and process them as needed. The C# version is usually much faster as well, which must mean that I'm not very good at PL/SQL either. I do not currently have access to LINQ. My question is, how best to package all these little C# programs, which are really just mini reports, that is, replacements for ugly SQL queries? Right now I'm actually using NUnit to hold them, and calling each report a [Test], even though they aren't really tests. NUnit just happens to provide a convenient packaging framework.

  • How lucene indexing ?

    - by user312140
    Hello I read some document about lucene ; also i read the document in this link ( http://lucene.sourceforge.net/talks/pisa ) . I don't really understand how lucene index documents and don't understand lucene work with which algorithm for indexing ? On above link , said lucene use this algorithm for indexing : * incremental algorithm: o maintain a stack of segment indices o create index for each incoming document o push new indexes onto the stack o let b=10 be the merge factor; M=8 for (size = 1; size < M; size *= b) { if (there are b indexes with size docs on top of the stack) { pop them off the stack; merge them into a single index; push the merged index onto the stack; } else { break; } } How this algorithm help us to have an optimize indexing ? Does lucene use B-tree algorithm or any other algorithm like that for indexing or have a paticular algorithm ? Thank you for reading my post .

  • Processing a database queue across multiple threads - design advice

    - by rwmnau
    I have a SQL Server table full of orders that my program needs to "follow up" on (call a webservice to see if something has been done with them). My application is multi-threaded, and could have instances running on multiple servers. Currently, every so often (on a Threading timer), the process selects 100 rows, at random (ORDER BY NEWID()), from the list of "unconfirmed" orders and checks them, marking off any that come back successfully. The problem is that there's a lot of overlap between the threads, and between the different processes, and their's no guarantee that a new order will get checked any time soon. Also, some orders will never be "confirmed" and are dead, which means that they get in the way of orders that need to be confirmed, slowing the process down if I keep selecting them over and over. What I'd prefer is that all outstanding orders get checked, systematically. I can think of two easy ways do this: The application fetches one order to check at a time, passing in the last order it checked as a parameter, and SQL Server hands back the next order that's unconfirmed. More database calls, but this ensures that every order is checked in a reasonable timeframe. However, different servers may re-check the same order in succession, needlessly. The SQL Server keeps track of the last order it asked a process to check up on, maybe in a table, and gives a unique order to every request, incrementing its counter. This involves storing the last order somewhere in SQL, which I wanted to avoid, but it also ensures that threads won't needlessly check the same orders at the same time Are there any other ideas I'm missing? Does this even make sense? Let me know if I need some clarification.

  • Using git (or some other VCS) at your company

    - by supercheetah
    Some friends of mine and I were talking recently about version control, and how they were using VSS at their jobs, and were probably going to be moving off of that soon. One of them said that his company will likely be going with Team Foundation Server. Eventually, the conversation did get around to talking about some of the open source VCSes out there, including git and SVN. None of us really knew about any companies that use either of these internally, although we imagined that a number of them did so for SVN, but we weren't too sure about git. I brought up Google and Android using it, but my friend figured that's only for the public facing source code, and that they may use something different for internal projects. Apparently it's more than just SCM that makes TFS so intriguing: Microsoft Sales people and support (although my friend did point out somethings to his managers that he thought might be misleading on MS' part) Integration of things beyond SCM, including project management (I'm just finding out that there are geared towards the same things for git) Again, it's Microsoft, and the transition from VSS to TFS seems logical (or does it?) I'm not much of a fan of SVN, so I didn't really bring it up much, but I am curious about whether or not git is used at your company for internal projects. Have you thought about it, and decided against it? Any reason why?

  • Automatically use inclusion tags (?) in a template, depending on installed apps

    - by Ludwik Trammer
    The title may be a little confusing, but I don't know how else to call it. I would like to create a Django project with a large set of applications you could arbitrary turn on or off using INSTALLED_APPS option in settings.py (you would obviously also need to edit urls.py and run syncdb). After being turned on an app should be able to automatically: Register it's content in site-wide search. Luckily django-haystack has this built-in, so it's not a problem. Register cron jobs. django-cron does exactly that. Not a problem. Register a widget that should be displayed on the homepage. The homepage should include a list of boxes with widgets form different applications. I thought about inclusion tags, because you can put them anywhere on a page and they control both content and presentation. The problem is I don't know how to automatically get a list of inclusion tags provided by my applications, and display them one by one on a homepage. I need a way to register them somehow, and then display all registered tags.

  • How to alter Postgres table data based on its contents?

    - by williamjones
    This is probably a super simple question, but I'm struggling to come up with the right keywords to find it on Google. I have a Postgres table that has among its contents a column of type text named content_type. That stores what type of entry is stored in that row. There are only about 5 different types, and I decided I want to change one of them to display as something else in my application (I had been directly displaying these). It struck me that it's funny that my view is being dictated by my database model, and I decided I would convert the types being stored in my database as strings into integers, and enumerate the possible types in my application with constants that convert them into their display names. That way, if I ever got the urge to change any category names again, I could just change it with one alteration of a constant. I also have the hunch that storing integers might be somewhat more efficient than storing text in the database. First, a quick threshold question of, is this a good idea? Any feedback or anything I missed? Second, and my main question, what's the Postgres command I could enter to make an alteration like this? I'm thinking I could start by renaming the old content_type column to old_content_type and then creating a new integer column content_type. However, what command would look at a row's old_content_type and fill in the new content_type column based off of that?
