• What is a good Javascript RDFa parser implementation?

  - by tremoloqui

  I am looking to implement a client side RDFa based formatting for a web application. This would be similar to Mark Birbeck's ubiquity-rdfa project. Mark's project looks fantastic but it has at least two drawbacks: It is slow. Adding RDFa formatting to a simple page causes a noticeable delay in page loading. It is complex. The ubiquity-rdfa project makes use of the w3c fresnel specification which is complex way to add simple annotations to client markup. I am looking for a lighter weight way of adding annotations through client code and I don't mind doing some work to get it. What I would like is a fast and reliable Javascript RDFa parser. Some implementations that I have found include: W3C RDFa bookmarklet parser Elias Torres RDFa extractor I am interested to know if you would recommend one of these, or another, RDFa Javascript implementation. Thanks!

• What does MSSQL execution plan show?

  - by tim

  There is the following code: declare @XmlData xml = '<Locations> <Location rid="1"/> </Locations>' declare @LocationList table (RID char(32)); insert into @LocationList(RID) select Location.RID.value('@rid','CHAR(32)') from @XmlData.nodes('/Locations/Location') Location(RID) insert into @LocationList(RID) select A2RID from tblCdbA2 Table tblCdbA2 has 172810 rows. I have executed the batch in SSMS with “Include Actual execution plan “ and having Profiler running. The plan shows that the first query cost is 88% relative to the batch and the second is 12%, but the profiler says that durations of the first and second query are 17ms and 210 ms respectively, the overall time is 229, which is not 12 and 88.. What is going on? Is there a way how I can determine in the execution plan which is the slowest part of the query?

• Processing file uploads before object is saved

  - by Dominic Rodger

  I've got a model like this: class Talk(BaseModel): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) seconds = models.IntegerField(blank = True, null = True) I want to validate before saving that the uploaded file is an MP3, like this: def is_mp3(path_to_file): from mutagen.mp3 import MP3 audio = MP3(path_to_file) return not audio.info.sketchy Once I'm sure I've got an MP3, I want to save the length of the talk in the seconds attribute, like this: audio = MP3(path_to_file) self.seconds = audio.info.length The problem is, before saving, the uploaded file doesn't have a path (see this ticket, closed as wontfix), so I can't process the MP3. I'd like to raise a nice validation error so that ModelForms can display a helpful error ("You idiot, you didn't upload an MP3" or something). Any idea how I can go about accessing the file before it's saved? p.s. If anyone knows a better way of validating files are MP3s I'm all ears - I also want to be able to mess around with ID3 data (set the artist, album, title and probably album art, so I need it to be processable by mutagen).

• Including inline javascript using content_for in rails

  - by TenJack

  I am using content_for and yeild to inject javascript files into the bottom of my layout but am wondering what the best practice is for including inline javascript. Specifically I'm wondering where the put the script type declaration: <% content_for :javascript do %> <script type="text/javascript"> ... </script> <% end %> or <% content_for :javascript do %> ... <% end %> <script type="text/javascript"> <%= yield :javascript %> </script> <% end %> I am using the first option now and wondering if it is bad to include multiple ... declarations within one view. Sometimes I have partials that lead to this.

• sharing web user controls across projects.

  - by Kyle

  I've done this using a regular .cs file that just extends System.Web.UI.UserControl and then included the assembly of the project that contains the control into other projects. I've also created .ascx files in one project then copied all ascx files from a specified folder in the properties-Build Events-Pre-build event. Now what I want to do is a combination of those two: I want to be able to use ascx files that I build in one project, in all of my other projects but I want to include them just using assembly references rather than having to copy them to my "secondary" projects as that seems a ghetto way to accomplish what I want to do. It works yes, but it's not very elegant. Can anyone let me know if this even possible, and if so, what the best way to approach this is?

• Can you define <=> in Ruby and then have ==, >, <, >=, and <= defined automatically?

  - by jeremy Ruten

  Here's part of my Note class: class Note attr_accessor :semitones, :letter, :accidental def initialize(semitones, letter, accidental = :n) @semitones, @letter, @accidental = semitones, letter, accidental end def <=>(other) @semitones <=> other.semitones end def ==(other) @semitones == other.semitones end def >(other) @semitones > other.semitones end def <(other) @semitones < other.semitones end end It seems to me like there should be a module that I could include that could give me my equality and comparison operators based on my <=> method. Is there one? I'm guessing a lot of people run into this kind of problem. How do you usually solve it? (How do you make it DRY?)

• What are some techniques to create scrollable areas?

  - by Omega

  I'm getting started with OpenGL ES on Android and I'd looking to learn some techniques to have a game map larger than the visible area. I'm assuming I've somehow got to ensure that the system isn't rendering the entire scene, including what's outside of the visible area. I'm just not sure how I'd go about designing this! This is for simple 2D top-down tile based rendering. No real 3D except what's inherent in OpenGL ES itself. Would anyone be able to get me started on the right path? Are there options that might scale nicely when I decide to start tilting my perspective and doing 3D?

• How to write stored procedures to separate files with mysqldump?

  - by Jader Dias

  The mysqldump option --tab=path writes the creation script of each table in a separate file. But I can't find the stored procedures, except in the screen dump. I need to have the stored procedures also in separate files. The current solution I am working on is to split the screen dump programatically. Is there a easier way? The code I am using so far is: mysqldump -p$PASSWORD --routines --skip-dump-date --no-create-info --no-data --skip-opt $DATABASE > $BACKUP_PATH/$DATABASE.sql mysqldump -p$PASSWORD --tab=$BACKUP_PATH --skip-dump-date --no-data --skip-opt $DATABASE

• Where is the iPhone's Date & Time getting it's time zone list

  - by johnbdh

  I can get a list of time zones with [NSTimeZone knownTimeZoneNames], but that only gives the time zone IDs which include one or 2 cities in each time zone. The Date & Time settings has a great list of cities and I have seen a few other apps that have the same if not similar lookup lists. Where do these lists come from?? I do need to relate a picked city to it's time zone like Date & Time does. Thanks, John

• Most Efficient Way of calling an external webservice in Java?

  - by Sudheer

  In one of our applications we need to call the Yahoo Soap Webservice to Get Weather and other related info. I used the wsdl2java tool from axis1.4 and generated th required stubs and wrote a client. I use jsp's use bean to include the client bean and call methods defined in the client which call the yahoo webservice inturn. Now the problem: When users make calls to the jsp the response time of the webservice differs greatly, like for one user it took less then 10 seconds and the other in the same network took more than a minute. I was just wondering if Axis1.4 queues the requests even though the jsps are multithreaded. And finally is there an efficient way of calling the webservice(Yahoo weather). Typically i get around 200 simultaneous requests from my users.

• design time usercontrols - I can't see anything!

  - by taglius

  newbie question, please forgive... I'm developing a Wpf UserControl that will eventually be bound to a business object. The usercontrol is little more than a series of laid out TextBlocks, and perhaps (later) an image or two. As I'm laying out the usercontrol, I can put dummy text into all the TextBlocks so I can see what the usercontrol will look like, but as soon as I change the text property to contain the Binding information: <TextBlock Margin="0,12.8,42,0" Name="lblLastName" FontSize="8" Height="19" VerticalAlignment="Top" Text="{Binding Mode=OneWay, Path=LastName}"/> Then I can no longer see the textbox, or any "placeholder" text. This makes it very difficult to adjust the location and sizes of all the controls on the UserControl. In WinFormas programming, you could set binding information independently of the Text property, so you could at least see the Placeholder text during design time development. It's going to be pretty hard to visually arrange a bunch of invisible TextBlocks! What's the standard solution for this?

• If you have an application localized in pt-br and pt-pt, what language you should choose if the syst

  - by Sorin Sbarnea

  If you have an application localized in pt-br and pt-pt, what language you should choose if the system is reporting only pt code (generic Portuguese)? This question is independent of the nature of the application, desktop, mobile or browser based. Let's assume you are not able to get region information from another source and you have to choose one language as the default one. The question does apply as well for more case including: * pt-pt and pt-br * en-us and en-gb * fr-fr and fr-CA * zh-cn, zh-tw, .... - in fact in this case I know that zh can be used as predominant language for Simplified Chinese where full code is zh-hans. For zh-tw, zh-hant-tw, zh-hk, zh-mo the proper code (canonical) should be zh-hant. In fact the question can be extended to: How to I determine the predominant languages for a specified meta-language? I need a solution that will include at least Portuguese, English and French.

• Should Python 2.6 on OS X deal with multiple easy-install.pth files in $PYTHONPATH?

  - by ahd

  I am running ipython from sage and also am using some packages that aren't in sage (lxml, argparse) which are installed in my home directory. I have therefore ended up with a $PYTHONPATH of $HOME/sage/local/lib/python:$HOME/lib/python Python is reading and processing the first easy-install.pth it finds ($HOME/sage/local/lib/python/site-packages/easy-install.pth) but not the second, so eggs installed in $HOME/lib/python aren't added to the path. On reading the off-the-shelf site.py, I cannot for the life of me see why it's doing this. Can someone enlighten me? Or advise how to nudge Python into reading both easy-install.pth files? Consolidating both into one .pth file is a viable workaround for now, so this question is mostly for curiosity value.

• Having trouble with event creation using the events.create API with the iPhone SDK

  - by MahatmaManic

  I'm using the FBConnect library in my iPhone app, and I'm trying to create Facebook events. After getting a valid session and verifying permissions, I'm using events.create and getting what looks like a valid event ID back from FB in a success response. Oddly the event isn't showing up on my account's Events page either in current or in past events. I thought the problem might be that the event might not include me as an attendee so I followed the successful events.create call with an events.rsvp call to set my status to "attending". That also gets back success from FB, but I'm still not seeing anything show up. Am I missing a step? Is there something other than Create and then RSVP that I need to do, or is there an error with the api/Facebook? I don't think I'm missing any of the required fields for event creation (name and start_time) and I am populating a lot of the other fields in event_info...

• How do I catch generic fault exceptions in Fitnesse?

  - by Dan Ryan

  Previously within my Fitnesse fixture I was specifying an expected WCF exception using: exception[FaultException] Since then I have converted the WCF service to return a strongly typed FaultContract. I am now getting the following failure message: exception[FaultException`1: "A file with the name DMS Documents/testFileWord.doc already exists. It was last modified by SHAREPOINT\system on 09 Mar 2010 15:36:14 -0000."] This is not unexpected but how do I check for strongly typed fault exceptions? Please note I cannot include the fault message as part of the check as it contains a date which changes (I check this separately).

• Clustered index dilemma - ID or sort?

  - by richardtallent

  I have a table with two very important fields: id INT identity(1,1) PRIMARY KEY identifiersortcode VARCHAR(900) My app always sorts and pages search results in the UI based on identifiersortcode, but all table joins (and they are legion) are on the id field. (Aside: yes, the sort code really is that long. There's a strong BL reason.) Also, due to O/RM use, most SELECT statements are going to pull almost every column. Currently, the clustered index is on id, but I'm wondering if the TOP / ORDER BY portion of most queries would make identifiersortcode a more attractive option as the clustered key, even considering all of the table joins going on. Inserts on the table and changes to the identifiersortcode are limited enough that changing my clustered index would be a problem for insert/update operations. Trying to make the sort code's non-clustered index a covering index (using INCLUDE) is not a good option. There are a number of large columns, and some of them have a lot of update activity.

• How do I create a Launcher in Ubuntu 9.1 that runs a shell script?

  Here's my situation: New to Ubuntu (just nstalled 9.10 Karmic Koala 64 bit) Purpose: to easily run PyCharm without too much typing (ie. cd... ./pycharm.sh) Want to create desktop Launcher instead of terminal & typing (without resorting to the "Run in Terminal" option) Tried to create Launcher to executes .sh script in Document directory Right-clicked Desktop Create Launcher a. Type == Application; Browse [insert absolute path to .sh script]; no luck b. Type == Application in Terminal; Browse ...ditto I'm open to any other alternatives that involve as little typing as possible. I would like to just start Ubuntu, click Launcher icons, and have terminals spring to life, running the intended scripts. Crazy? No. Lazy? Probably. Productive? Hopefully :)
