• code throws std::bad_alloc, not enough memory or can it be a bug?

  - by Andreas

  I am parsing using a pretty large grammar (1.1 GB, it's data-oriented parsing). The parser I use (bitpar) is said to be optimized for highly ambiguous grammars. I'm getting this error: 1terminate called after throwing an instance of 'std::bad_alloc' what(): St9bad_alloc dotest.sh: line 11: 16686 Aborted bitpar -p -b 1 -s top -u unknownwordsm -w pos.dfsa /tmp/gsyntax.pcfg /tmp/gsyntax.lex arbobanko.test arbobanko.results Is there hope? Does it mean that it has ran out of memory? It uses about 15 GB before it crashes. The machine I'm using has 32 GB of RAM, plus swap as well. It crashes before outputting a single parse tree. The parser is an efficient CYK chart parser using bit vector representations; I presume it is already near the limit of memory efficiency. If it really requires too much memory I could sample from the grammar rules, but this will decrease parse accuracy of course.

• ExpressionEngine 2 module "tag cannot be processed"

  - by Phil Sturgeon

  So I have turned my hand to ExpressionEngine and while the backend crud was easy enough getting the frontend working with template syntax is proving difficult, even at the "hello world" level. expressionengine/third_party/rest/mod.rest.php class Rest { var $return_data = ''; function Rest() { $this->EE =& get_instance(); return $this->return_data = 'HAI'; } } // END REST Class /* End of file REST.php */ /* Location: ./application/libraries/REST.php */ Then im calling it directly in a new empty template: {exp:rest} So I'm expecting to see "HAI" but I get: Error The following tag cannot be processed: {exp:rest} Please check that the ‘rest’ module is installed and that ‘rest’ is an available method of the module Any ideas? The module is installed and the backend is running fine.

• Core Data table record count

  - by user339633

  I have an entity called Person and it has a relationship called participatingGames, to another entity called GameParticipant. I (apparently) can retrieve the number of matches in the GameParticipant entity using this simple code in the Person object I created from the entity in the model: [self.participatingGames count]; However, I'd just like to retrieve the number of Person records and one might guess the syntax for this is just as simple. I have lots of books including those by Jeff LaMarche, but those sources and what I find around here make me wonder if I need to set up a fetchedResultsController just to know the count of some entity. My background is in SQL, so of course it seems odd that what would take 15 seconds to code in any other environment seems like such a well-guarded secret in Core Data. I'm using iPhone SDK 3.1.4 under OSX 10.5.8 Suggestions?

• How to use a variable to specify filegroup in MSSQL

  - by gt

  I want to alter a table to add a constraint during upgrade on a MSSQL database. This table is normally indexed on a filegroup called 'MY_INDEX' - but may also be on a database without this filegroup. In this case I want the indexing to be done on the 'PRIMARY' filegroup. I tried the following code to achieve this: DECLARE @fgName AS VARCHAR(10) SET @fgName = CASE WHEN EXISTS(SELECT groupname FROM sysfilegroups WHERE groupname = 'MY_INDEX') THEN QUOTENAME('MY_INDEX') ELSE QUOTENAME('PRIMARY') END ALTER TABLE [dbo].[mytable] ADD CONSTRAINT [PK_mytable] PRIMARY KEY ( [myGuid] ASC ) ON @fgName -- fails: 'incorrect syntax' However, the last line fails as it appears a filegroup cannot be specified by variable. Is this possible?

• IntelliJ doesn't seem to pickup certain sbt libraries, no code completion

  - by Blankman

  I am using sbt console in my terminal to compile my scala/play project. I am using intellij to edit my source code, basically using it just for getting some code completion and navigation etc. For some reason certain libraries don't seem to load correctly. For example, I added elastic search to my Dependancies.scala file, reloaded sbt and everything compiles fine but for some reason IntelliJ doesn't pickup the jars correctly i.e. they are in red and there is no syntax completion. How can I fix this? I tried shutting intellij down and restarting it but the problem remains. I am using Intelli 13.1.3 (ultimate)

• CSS3 box-shadow + inset + RGBA

  - by mkotechno

  I'm doing some tests with new features of CSS3, but this combination only works in lastest versions of Chrome and Firefox, but not in Safari or Opera: box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -webkit-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -moz-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); I really don't know if they fails in the box-shadow itself, in the inset parameter, or in RGBA color. It's a syntax error or simply Safari and Opera lacks on this?

• INSERT INTO ... SELECT FROM ... ON DUPLICATE KEY UPDATE

  - by dnagirl

  I'm doing an insert query where most of many columns would need to be updated to the new values if a unique key already existed. It goes something like this: INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, inact, inadur, inadist, smlct, smldur, smldist, larct, lardur, lardist, emptyct, emptydur) SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, t.inact, t.inadur, t.inadist, t.smlct, t.smldur, t.smldist, t.larct, t.lardur, t.lardist, t.emptyct, t.emptydur FROM tmp t WHERE uid=x ON DUPLICATE KEY UPDATE ...; //update all fields to values from SELECT, except for exp_id, created_by, location, animal, starttime, endtime I'm not sure what the syntax for the UPDATE clause should be. How do I refer to the current row from the SELECT clause?

• Generate markdown from source code doc-comments

  - by erikkallen

  Is there any easy way to generate markdown from source code comments? I'm looking for something similar to Sandcastle, but with Markdown (or something like it) as output. The full story is that I use DokuWiki to generate documentation. It has many nice properties, including that all its data is stored in text files. So my idea is that I should somehow be able to get my API docs into the same place as the rest of my documentation. So far my best bet seems to be to write a custom documenter for NDoc3, but perhaps someone has already done something similar which would save me the trouble. I realize I might need to tweak it a little due to slight syntax differences.

• E4X in ActionScript

  - by Brian Genisio

  Hey all, Looking at the E4X implementation in ActionScript, it occurs to me that they had to figure out how to do three things that I am not sure can be done within ActionScript regularly: Properties/Getters prefixed with @: var myAttribute = xmlPerson.@name; Nameless functions for filtering: xmlData.person.(/* predicate */) lambda syntax for predicates: xmlData.person.(@name == "Brian") So here is my question: Are these just one-off capabilities (much like Vector.<>) they put in just for E4X, therefore keeping out of reach for us? Or do we, as ActionScript developers, have access to these features? More specifically, I'd love to get access to the expression tree of that lambda predicate for my own code (not tied to the XML classes in any way). I figured out that this is called the "filter operator"... but I am not sure how to harness it. Not sure I can... since ActionScript does not allow for operator overloading :(

• What are the virtues of using XML comments in .NET?

  - by Michal Czardybon

  I can't understand the virtues of using XML comments. I know they can be converted into nice documentation external to the code, but the same can be achieved with the much more concise DOxygen syntax. In my opinion the XML comments are wrong, because: They obfuscate the comments and the code in general. (They are more difficult to read by humans). Less code can be viewed on a single screen, because "summary" and "/summary" take additional lines. They suggest that all method parameters have to be commented, whereas 90% of them are obvious and SHOULD be left not commented. The only problem I have with this is that my point of view seems to be in minority. Why?

• How do I get a right outer join in L2E?

  - by Dan

  I have two tables that I set up through the VS Entity Data Model Diagram tool. I'm trying to do a right outer join and it doesn't return results from the 2nd table. I have set up a 0..1 to MANY relationship from the diagram tool. When I run a Linq-To-Entities query, it still defaults to an INNER JOIN. From my understanding of entities, if I set up the relationship using VS, when I join the tables, it should automagically figure out the join syntax based on the relationship I supply. It doesn't seem to be doing that. I am using EF v1 (not Linq-to-Sql). Query I'm running: from s in SomeTable join t in SomeOtherTable on s.ID equals t.ID select new { s.MyFieldName, t.MyOtherFieldName }

• Python - which multi platform GUI framework to use?

  - by Iacopo

  Hi, I've written a Python GUI application and made it run on Linux, Windows and Mac. The framework I'm using is PyGtk. The final result is not really good: the application looks horrible on Mac, and it is not really 'native' neither on Windows. Furthermore on Mac the windows' behavior is sometimes wrong, with modal dialogs appearing below the main windows. I've explored other frameworks and I've found that a porting may be really hard: PyQt it is huge, difficult to install and to distribute under Mac; PyGui is poor: I need tables and tree views at least; wxPython state explicitly that you have to use a custom python build for Mac Tkinter: didn't check it, only have the impression that it is obsolete I know this question may appear similar to http://stackoverflow.com/questions/394039/which-python-gui-framework but in that thread the portability issue is not really taken in account. Windows and Mac are a must, since most of my user have that systems. Can you also suggest some books?

• Query regarding the Nhibernate many to many mapping

  - by Pramod

  Hi, I have a requirement where i have 3 dimension tables (employee, project, technology) and a common fact table which has the key id's of all these three tables. My question goes like this... How do i create a mapping table (fact table) having these three columns - emp_id, proj_i and tech_i. I know we can achieve this for two tables using the below syntax: HasManyToMany(x = x.Empl) .Table("Emp_Proj") .ParentKeyColumn("Emp_i") .ChildKeyColumn("Proj_I") .Inverse() .Cascade.All(); How can i add another child key column (tech_i) to the above mapping table?

• C/C++ enum and char * array

  - by Eric M

  Ran accross the following code in an article and didn't think it was standard C/C++ syntax for the char* array. As a test, both Visual C++ (visual studio 2005) and C++ Builder Rad XE both reject the 2nd line. Without using #defines, anyone have any tricks/tips for keeping enums and a string array sort of in sync without resorting to STL ? More of a curiosity question. enum TCOLOR { RED, GREEN, BLUE }; char *TNCOLOR[] = { [RED]="Red", [GREEN]="Green", [BLUE]="Blue" }; as an aside, the article this came from is quite old and I believe this might work under GCC but have not tested.

• JQuery make an array - how/what is best

  - by russp

  I have 4 serailized arrays that I want to pass to php for processing. What is the best way to combine them into a single array example: serial_1 = $('#col1').sortable('serialize'); serial_2 = $('#col2').sortable('serialize'); serial_3 = $('#col3').sortable('serialize'); serial_4 = $('#col4').sortable('serialize');` each serialized array relates to a column/section of the page (col1,col2 etc.) What I need to do/would like to do is create a single array that puts the serialized array inside another array for a single post. example: var new_array = serilaize(col_1(serial_1),col2(serial_2),col3,(serial_3),col4(serial_4)) I KNOW THAT IS NOT RIGHT as I have no idea in JQuery how to right the correct syntax. This new array is to be posted via ajax like this: $.ajax({ url: "test.php", type: "post", data: new_array, error: function(){ alert('SOME ERROR MESSAGE'); } }); Thanks in advance

• Using SortableRows and know when rows have been moved

  - by DW

  I want to take advantage of the sortableRows property of the jqGrid. How do I detect when a row has been moved. I have studied the documentation and looked for examples but haven't found much. I do believe it is something like jQuery("#grid").sortableRows({connectWith:'#gird', ondrop: function(){ alert("row moved") }}); but that does not work. I can move the rows, but don't seemed to have trapped the event. Is there something wrong with my syntax or my approach in general. Basically, I need to know that the rows have been rearranged so I can be sure they get saved with their new order. Thanks

• How can I serialize the values of checked checkboxes in an iFrame into a hidden form field on clicki

  - by Frank Bailey

  I have an iFrame like so: <iframe width="100%" frameborder="0" height="470" allowtransparency="true" name="productframe" id="productframe" style="border-bottom:1px solid #eee"></iframe> The iframe contains several line items drawn from a sql server db, and I can check any of the checkboxes I want to perform a task with - in this case delete them. I have a button in the parent document that says "Delete selected", and I'd like to be able to click this button and populate a hidden field in my parent page with the values of the selected checkboxes in the child iframe. My checkboxes look like this: <input id="Checkbox1" type="checkbox" value="47" title="Select this row" name="selectItem"/> I have an instance of jquery on my parent page so I can make use of jquery selectors, I just have no clue as to the syntax needed to do this. Thanks in advance to anyone who can help me on this.

• How to do manual DI with deep object graphs and many dependencies properly

  - by Fabian

  I believe this questions has been asked in some or the other way but i'm not getting it yet. We do a GWT project and my project leader disallowed to use GIN/Guice as an DI framework (new programmers are not going to understand it, he argued) so I try to do the DI manually. Now I have a problem with deep object graphs. The object hierarchy from the UI looks like this: AppPresenter-DashboardPresenter-GadgetPresenter-GadgetConfigPresenter The GadgetConfigPresenter way down the object hierarchy tree has a few dependencies like CustomerRepository, ProjectRepository, MandatorRepository, etc. So the GadgetPresenter which creates the GadgetConfigPresenter also has these dependencies and so on, up to the entry point of the app which creates the AppPresenter. Is this the way manual DI is supposed to work? doesn't this mean that I create all dependencies at boot time even I don't need them? would a DI framework like GIN/Guice help me here?

• HTML: How to get a child element to show behidn (lower z-index) than its parent

  - by dclowd9901

  I need for a certain dynamic element to always appear on top of another element, no matter what order in the DOM tree they are. Is this possible? I've tried z-index (with position: relative), and it doesn't seem to work. I hate to be vague, but this is the simplest way I can think of asking this question without explaining its purpose ad nauseum. So, to recap, I need <div class="a"> <div class="b"></div> </div> <div class="b"> <div class="a"></div> </div> To display exactly the same when rendered. And for flexibility purposes (I'm planning on distributing a plugin that needs this functionality), I'd really like to not have to resort to absolute or fixed positioning.

• is there a way to get a "subtree" from hclust ? (R)

  - by Tal Galili

  Hello all, I wish to create a "subtree" from an hclust object. For example, let's say I have the following object: a <- list() # initialize empty object a$merge <- matrix(c(-1, -2, -3, -4, 1, 2, -5,-6, 3,4), nc=2, byrow=TRUE ) a$height <- c(1, 1.5, 3,4,4.5) # define merge heights a$order <- 1:6 # order of leaves(trivial if hand-entered) a$labels <- 1:6# LETTERS[1:4] # labels of leaves class(a) <- "hclust" # make it an hclust object plot(a) # look at the result Now I wish the extract from it the following subtree: a <- list() # initialize empty object a$merge <- matrix(c(-1, -2, -3, -4, 1, 2 ), nc=2, byrow=TRUE ) a$height <- c(1, 1.5, 3) # define merge heights a$order <- 1:4 # order of leaves(trivial if hand-entered) a$labels <- 1:4# LETTERS[1:4] # labels of leaves class(a) <- "hclust" # make it an hclust object plot(a) # look at the result How could I access it? (I know that cutree could get me the objects of the sub tree, but not create an actual hclust object) Thanks for any help, Tal

• Why do external Java libraries paths have to be refreshed in eclipse between starts?

  - by Jason

  For my school projects, I use the joda-time API for generating timestamps that are used for file names and logging. Getting eclipse to recognize the library is no problem. However, when I start eclipse between reboots, I get the red X in the project tree because the external API cannot be found, even though the file path has not changed. So each time, I have to go to the Libraries tab in Build Path to re-target the API. Frankly, this is getting to be a PIMA. So is there any way to have the path be permanent, so I don't have to do the Build Path rigmarole all the time?
