• How does one inject variables into page templates from a custom Drupal module?

  - by Michael T. Smith

  We've created a custom module for organizing and publishing our newsletter content. The issue I'm running into now -- and I'm new to theming and Drupal module development, so it could just be a knowledge issue as opposed to a Drupal issue -- is how to get each newsletter themed. At this point the URL structure of our newsletter will be: /newsletters/{newsletter-name}/{edition-name}/{issue-date} which means that we can create template files in our theme using filenames like page-newsletters-{newsletter-name}-{edition-name}.tpl.php, which is great. The one issue I'm running into is that all of the content comes through in the $content variable of the theme. I'd like to have it come through as different variables (so that I can, inside the theme, place certain content in certain areas.) Is there a proper way for doing this?

• How do I ignore set and get when assigning or retrieving a value?

  - by cbsch

  Hello. Is it possible to ignore set and get when I'm assigning to or retrieving a value? In specific, I'm inheriting from a class that has a property declared like this: public Int32 Value { get; set; } What I'd like to do is to override it and do something useful in those set and get's. The problem appears when I override it, I also have to manually assign, or return the value from the property. If I do something like this: override public Int32 Value { get { return this.Value; } set { this.Value = value; // do something useful } Then I'm creating an infinite loop. Is there a way to set or get the value without invoking the code in set and get, or do I have to make a separate name for the actual variable?

• Generate n-dimensional random numbers in Python

  - by Magsol

  I'm trying to generate random numbers from a gaussian distribution. Python has the very useful random.gauss() method, but this is only a one-dimensional random variable. How could I programmatically generate random numbers from this distribution in n-dimensions? For example, in two dimensions, the return value of this method is essentially distance from the mean, so I would still need (x,y) coordinates to determine an actual data point. I suppose I could generate two more random numbers, but I'm not sure how to set up the constraints. I appreciate any insights. Thanks!

• Using Parallel Extensions with ThreadStatic attribute. Could it leak memory?

  - by the-locster

  I'm using Parallel Extensions fairly heavily and I've just now encountered a case where using thread locla storrage might be sensible to allow re-use of objects by worker threads. As such I was lookign at the ThreadStatic attribute which marks a static field/variable as having a unique value per thread. It seems to me that it would be unwise to use PE with the ThreadStatic attribute without any guarantee of thread re-use by PE. That is, if threads are created and destroyed to some degree would the variables (and thus objects they point to) remain in thread local storage for some indeterminate amount of time, thus causing a memory leak? Or perhaps the thread storage is tied to the threads and disposed of when the threads are disposed? But then you still potentially have threads in a pool that are longed lived and that accumulate thread local storage from various pieces of code the threads are used for. Is there a better approach to obtaining thread local storage with PE? Thankyou.

• How come ftp protocol produces transmission errors sometimes if the data is using TCP, which is checksummed?

  - by Cray

  Every once in a while, downloading (especially large) files through ftp will produce errors. I am guessing that's also partly the reason why all major sites are publishing external checksums along with their downloads. How is this possible if ftp goes through TCP, which has checksum inbuilt and resends data if it is transmitted corruptly? One could argue that this is due to the short length of the CRC in the TCP protocol (which is 16bit I think, or something like that), and the collisions are simply happening too often. but 1) for this to be true, not only must there be a CRC collision, but also the random network error must modify both the CRC in the packet, and the packet itself so that the CRC will be valid for the new packet... Even with 16 bitCRC, is that so likely? 2) There are seemingly not many errors in, say, browsing the web which also goes through TCPIP.

• Command$ value disappears

  - by AngryHacker

  I have a VB6 app. I am trying to figure out what command line parameters got passed into the application. If I type in ? Command$ into the Immediate window, it prints out the command line params fine. Same, if I place Command$ into the Watch window. However, if I assign the Command$ function to a string: Dim s as string s = Command$ the s variable will be empty. What am I missing here? I should mention that the code in question is located not in the main form, but in a DLL 2 levels down (e.g. the form calls DLL1, then DLL1 calls DLL2).

• Three20 - add items to launcherView after viewDidLoad

  - by lostInTransit

  Hi I am getting a list of image URLs and corresponding names at run time in my app. I would like to add these images to a TTLauncherView object that I have. Cannot add these in loadView. I am making a call to the method for getting my data in a separate thread. Once the thread completes, I add the TTLauncherItem objects to an array and set the "pages" variable of the LauncherView. But for some reason, the view is not updated and I don't see anything on it. Can someone please let me know how to refresh the launcherview after adding items to it in methods other than loadView? Thanks.

• jquery html attribute not working in IE

  - by Gopal

  I am using country and state dropdowns in my form. Whenever the user selects the country in the dropdown, the respective states of the country will populate in the states dropdown. I am populating the states in the dropdown using ajax call. The problem is that the states get populated in Mozilla but it doesnt work in IE. I guess there is some problem in jquery while loading the states in the states dropdown. The jquery code i am using is $('select#edit-country').change(function(e) { $.getJSON("loadContactUsStates",{id: $(this).val(), ajax: 'true'}, function(j){ var options = ''; for (var i = 0; i < j.length; i++) { options += '<option value="' + j[i].optionValue + '">' + j[i].optionDisplay + '</option>'; } <!-----I guess the problem is with the below line------------------> $("select#edit-state").html(options); })//end json });

• R: ggplot2, how to add a number of layers to a plot at once to reduce code

  - by John

  library(ggplot2) This code produces a nice looking plot: qplot(cty, hwy, data = mpg, colour = displ) + scale_y_log2() + labs(x="x axis") + labs(y="y axis") + opts(title = "my title") But I want to setup variables to try and to reduce code repetition: log_scale <- scale_y_log2() xscale <- labs(x="x axis") yscale <- labs(y="y axis") title <- opts(title = "my title") my_scales <- c(log_scale, xscale, yscale, title) # make a variable to hold the scale info changes above So that I can do this and add a bunch of things at the same time: qplot(cty, hwy, data = mpg, colour = displ) + my_scales # add these to your plot. but I get this error: Error in object$class : $ operator is invalid for atomic vectors I realize that the things going into my_scales need to be layers / different types of objects, but I don't see what they should be.

• JavaScript: jQuery Datepicker - simple highlighting of specific days, who can help? (source inside)

  - by Klicker.eu

  Hi guys, i want to use the Datepicker for highlighting specific dates. Here is my latest code: <script type="text/javascript"> var dates = [30/04/2010, 01/05/2010]; $(function(){ $('#datepicker').datepicker({ numberOfMonths: [2,3], dateFormat: 'dd/mm/yy', beforeShowDay: highlightDays }); function highlightDays(date) { for (var i = 0; i < dates.length; i++) { if (dates[i] == date) { return [true, 'highlight']; } } return [true, '']; } }); </script> my CSS is: #highlight, .highlight { background-color: #cccccc; } Well the calendar comes up, but there is nothing highlighted. Where is the problem in my code? If anyone could help that would be great. Another option/solution could be: disable all dates, but make available only dates in an array. Thanks!

• Mapping functions of 2D numpy arrays

  - by perimosocordiae

  I have a function foo that takes a NxM numpy array as an argument and returns a scalar value. I have a AxNxM numpy array data, over which I'd like to map foo to give me a resultant numpy array of length A. Curently, I'm doing this: result = numpy.array([foo(x) for x in data]) It works, but it seems like I'm not taking advantage of the numpy magic (and speed). Is there a better way? I've looked at numpy.vectorize, and numpy.apply_along_axis, but neither works for a function of 2D arrays. EDIT: I'm doing boosted regression on 24x24 image patches, so my AxNxM is something like 1000x24x24. What I called foo above applies a Haar-like feature to a patch (so, not terribly computationally intensive).

• Setting Curl's Timeout in PHP

  - by Moki

  I'm running a curl request on an eXist database through php. The dataset is very large, and as a result, the database consistently takes a long amount of time to return an XML response. To fix that, we set up a curl request, with what is supposed to be a long timeout. $ch = curl_init(); $headers["Content-Length"] = strlen($postString); $headers["User-Agent"] = "Curl/1.0"; curl_setopt($ch, CURLOPT_URL, $requestUrl); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERPWD, 'admin:'); curl_setopt($ch,CURLOPT_TIMEOUT,1000); $response = curl_exec($ch); curl_close($ch); However, the curl request consistently ends before the request is completed (<1000 when requested via a browser). Does anyone know if this is the proper way to set timeouts in curl?

• How do I check if a user is authenticated with NickServ using POE::Component::IRC::State in Perl?

  - by Troy

  I'm trying to test whether a user is registered on FreeNode. nick_info() doesn't seem to return information about this, so I want to use $irc-yield(whois = $nick); and then grab the irc_whois event's reply. The problem is that I want to wait until this event is fired, so I created a global variable $whois_result and wrote a sub like this: sub whois { my $nick = $_[0]; $whois_result = 0; $irc->yield(whois => $nick); while($whois_result == 0) { } return $whois_result; } with the irc_whois handler looking like: sub on_whois { $whois_result = $_[ARG0]; print "DEBUG: irc_whois fired.\n"; } Unfortunately, the event can't fire while the loop is running so this hangs. I'm sure there's a better way to do this, but I'm not familiar enough with this kind of programming to know. Any help would be greatly appreciated.

• Vim: Call an ex command (set) from function?

  - by sixtyfootersdude

  Drawing a blank on this, and google was not helpful. Want to make a function like this: function JakPaste() let tmp = :set paste? if tmp == "paste" set nopaste else set paste endif endfunction map <F2> :call JakPaste()<CR> However this does not work. I have isolated the broken line: function JakPaste() let tmp = set paste? endfunction map <F2> :call JakPaste()<CR> Pressing F2 results in this error: Error detected while processing function JakPaste: line 1: E121: Undefined variable: set E15: Invalid expression: set paste? Hit ENTER or type command to continue How should I call an ex command (set) from a vim function? This seems somewhat relevant however I still don't get it.

• Help with Strings in C

  - by Anon

  Given the char * variables name1 , name2 , and name3 , write a fragment of code that assigns the largest value to the variable max (assume all three have already been declared and have been assigned values). I've tried and came up with this: if ((strcmp(name1,name2)0)&&(strcmp(name1,name3)0)){ max=name1; } else if ((strcmp(name2,name1)0)&&(strcmp(name2,name3)0)){ max=name2; } else if ((strcmp(name3,name1)0)&&(strcmp(name3,name2)0)){ max=name3; } However, I get this error Your code is incorrect. You are not handling the situation                where two or more strings are equal.

• How can i query for null values in entity framework?

  - by AZ

  I want to execute a query like this var result = from entry in table where entry.something == null select entry; and get an IS NULL generated. Edited: After the first two answers i feel the need to clarify that I'm using Entity Framework and not Linq to SQL. The object.Equals() method does not seem to work in EF. Edit no.2: The above query works as intended. It correctly generates IS NULL. My production code however was var value = null; var result = from entry in table where entry.something == value select entry; and the generated SQL was something = @p; @p = NULL. It seems that EF correctly translates the constant expression but if a variable is involved it treats it just like a normal comparison. Makes sense actually. I'll close this question

• Use same project to create multiple applications on same device

  - by Mark.Prof

  I am deploying a reader application with it's document packaged in the asset folder. Any branding is done by dynamically generating xml and resources as appropriate. The application name itself is also generated. Since it is the tag's "package" property that needs to be unique, I nevertheless have a problem installing more than one instance of this app. I would like to dynamically edit the manifest package attribute's value to reflect the document and brand that I am building. But this causes build problems, specifically the location of R.java is no longer available to the component package under which the code resides. Originally, the component package is the same as the application manifest package. But precisely this manifest package name is the part that needs to be variable. How should I best proceed?

• setTimeout(fun) with a single argument

  - by Elazar Leibovich

  The HTML5 specifications states that setTimeout can be run without the additional "timeout" argument which is supposed to say after how many milliseconds will the function "handler" be scheduled. handle = window . setTimeout( handler [, timeout [, arguments ] ] ) Schedules a timeout to run handler after timeout milliseconds. Any arguments are passed straight through to the handler. However, I failed to find anywhere which explains what happens when no "timeout" time period is set. An example usage is, the animation implementation int the Raphael library. animationElements[length] && win.setTimeout(animation);

• Using implicit conversion as a substitute for multiple inheritance in .NET

  - by Daniel Plaisted

  I have a situation where I would like to have objects of a certain type be able to be used as two different types. If one of the "base" types was an interface this wouldn't be an issue, but in my case it is preferable that they both be concrete types. I am considering adding copies of the methods and properties of one of the base types to the derived type, and adding an implicit conversion from the derived type to that base type. Then users will be able treat the derived type as the base type by using the duplicated methods directly, by assigning it to a variable of the base type, or by passing it to a method that takes the base type. It seems like this solution will fit my needs well, but am I missing anything? Is there a situation where this won't work, or where it is likely to add confusion instead of simplicity when using the API?

• Eclipse takes ages to display breakpoint when running tomcat

  - by Ryan

  Hi, When tomcat hits a breakpoint in Eclipse, the execution thread stops, but the breakpoint takes absolutely ages to appear in Eclipse. The same is true if I try to inspect a variable; the first time takes about 2 minutes. After that, the debug session is fine. What with that and the CONSTANT need to keep re-publishing to tomcat every time I change something, it's driving me nuts. Does anybody have any ideas why it's so slow? Also, how can I stop tomcat restarting the webapp every time I try to change something during a debug session? I am sure it never used to do that... Eclipse is 3.3.1.1 with J2EE Standard Tools and Web Standard Tools. Tomcat is 5.5 Thanks a lot for any advice! Ryan

• Ending php sessions for debugging purposes

  - by Bill Zimmerman

  Hi, This might be very easy to do, but I haven't been able to figure it out. Basically, I have a loosely couple web-app written in python and php. The python code uses PHP sessions (generated from the PHP app when the user logs in) to check if the user is logged in/has permission to access the given python resource. My question is this: What is the easiest way to force all active sessions to timeout. I would like to do this for debugging purposes, to test out the python code. I tried changing the session.max_lifetime PHP variable, but that still doesn't guarantee that the session has ended and is removed. I tried just deleting the file, but this seems to cause problems (when i refresh the php page, errors show up in my apache logs and it won't reload quickly) Any ideas?

• Allowing optional variables with Rewrite Cond

  - by James Doc

  I currently have the following code: RewriteCond %{REQUEST_URI} !assets/ RewriteCond %{REQUEST_URI} !uploads/ RewriteRule ^([a-z|0-9_&;=-]+)/([a-z|0-9_&;=-]+) index.php?method=$1&value=$2 [NC,L] This works perfectly to redirect 'page/home' to 'index.php?method=page&value=home. However at some points I need to add an extra variable or two to the query string such as 'admin/useraccounts/mod/2'. When I simply tack on bits to the end of the rewrite rule it works if all the variables are 'page/home/rand/rand' or 'admin/useraccounts/mod/2', but if anything is missing such as 'page/home' I get a 404. What am I doing wrong? Many thanks.
