• What is __path__ useful for?

  - by Jason Baker

  I had never noticed the __path__ attribute that gets defined on some of my packages before today. According to the documentation: Packages support one more special attribute, __path__. This is initialized to be a list containing the name of the directory holding the package’s __init__.py before the code in that file is executed. This variable can be modified; doing so affects future searches for modules and subpackages contained in the package. While this feature is not often needed, it can be used to extend the set of modules found in a package. Could somebody explain to me what exactly this means and why I would ever want to use it?

• How do I interpolate between points without going beyond them?

  - by user1774893

  I have data of variable lengths (reaching movements recorded in 2D) and want to create a function that will resample this data to a uniform length (500 samples). However, I want matlab to only resample between the maximum and minimum values given, without adding any additional distance. For instance, if I resample the matrix [1:1:10], the resampled matrix should have a minimum value of 1 and a maximum value of 10. So far I've tried the following: x = [1:1:10]; interp(x, 500 / length(x)); This, however, gives values above my maximum specified value of 10. Is there any way I can get matlab to resample/interpolate solely between two points, without extending beyond them?

• Equal height divs with footer always at bottom of tallest div

  - by nukegara

  I was wondering if this were possible, and if it is the best way to go about this: example image (since I'm not allowed to post pics yet ^^) So, not only does each column have to be of equal height, but each column also has its own individual footer. I saw this post httx://stackoverflow.com/questions/1347366/div-at-bottom-of-window-and-adaptable-height-div (I also can't post more than one link....) - how could I rework this technique to apply to the bottom of the divs and not the bottom of the window? *edit - each column will have content that will constantly change and be of variable height. I'm thinking I could just figure out the equal height columns first, then just absolute position a footer div within those columns. Does its parent div then have to be position: relative?

• Escaping if/else in Jade template

  - by Collin Estes

  So I have a simply block of html in my jade template with a loop: each dude, i in dudes div(class='someClass') div.otherStuff span.someContent #{name} I want to apply a data attribute to my top most div when a certain looping condition is met, in this case the first dude, I set it up like this each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') else div(class='someClass') div.otherstuff span.someContent Setup like this it causes the div.otherStuff div and the span.someContent to only display on the else condition. I've moved the tab spaces around on those items but I can't get it escape that else and give the div.otherStuff and span.someContent to both the first dude and the subsequent dudes after that. I've also tried setting that data attr to a variable and trying to apply it that way but without any success. What I end up doing to get around it is this: each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') div.otherstuff span.someContent else div(class='someClass') div.otherstuff span.someContent How do I escape that if/else so I dont have to duplicate the div.otherStuff and span.someContent?

• Is there a way to echo this only once and not have it repeat?

  - by Fernando

  I have the following query: $select = mysql_query("SELECT * FROM posts WHERE id = $postIds"); while ($return = mysql_fetch_assoc($select)) { $postUrl = $return['url']; $postTitle = $return['title']; echo "<h1><a href='$postUrl'>".$postTitle."</a></h1>"; } Now the problem is, the variable $postIds often times contain the same id multiple times. So the title of the post echos itself multiple times. Is there a way to have it echo only once?

• Is there a single query that can update a "sequence number" across multiple groups?

  - by Drarok

  Given a table like below, is there a single-query way to update the table from this: | id | type_id | created_at | sequence | |----|---------|------------|----------| | 1 | 1 | 2010-04-26 | NULL | | 2 | 1 | 2010-04-27 | NULL | | 3 | 2 | 2010-04-28 | NULL | | 4 | 3 | 2010-04-28 | NULL | To this (note that created_at is used for ordering, and sequence is "grouped" by type_id): | id | type_id | created_at | sequence | |----|---------|------------|----------| | 1 | 1 | 2010-04-26 | 1 | | 2 | 1 | 2010-04-27 | 2 | | 3 | 2 | 2010-04-28 | 1 | | 4 | 3 | 2010-04-28 | 1 | I've seen some code before that used an @ variable like the following, that I thought might work: SET @seq = 0; UPDATE `log` SET `sequence` = @seq := @seq + 1 ORDER BY `created_at`; But that obviously doesn't reset the sequence to 1 for each type_id. If there's no single-query way to do this, what's the most efficient way? Data in this table may be deleted, so I'm planning to run a stored procedure after the user is done editing to re-sequence the table.

• How to pass extra variables in URL with Wordpress

  - by Chuck D

  I am having trouble trying to pass an extra variable in the url to my wordpress installation. For example /news?c=123 For some reason, it works only on the website root www.example.com?c=123 but it does not work if the url contains any more information www.example.com/news?c=123. I have the following code in my functions.php file in the theme directory. if (isset($_GET['c'])) { setcookie("cCookie", $_GET['c']); } if (isset($_SERVER['HTTP_REFERER'])) { setcookie("rCookie", $_SERVER['HTTP_REFERER']); } Any Ideas?

• Help with dates in Android

  - by SamRowley

  Hi guys, Looking for a bit of help with taking a dat from a DatePicker Widget and storing it in an sqlite database within the app. I have the following code: java.util.Date utilDate = null; String y = Integer.toString(date.getDayOfMonth()) + "/" + (date.getMonth()+1) + "/" + Integer.toString(date.getYear()); SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyy"); utilDate = formatter.parse(y); java.sql.Date z = new java.sql.Date(utilDate.getDate()); x = z.toString(); Log.v("The date: ", x); } Where date is the DatePicker widget. If I output the utilDate variable (i.e. the Java version of date) using logCat it seems to work fine and gives me a format like: Tue Jan 04 00:00:00 GMT 2011 which I am expecting but using the code above to get the sql version of the date, it always gives me the date 1970-01-01. I'm pretty sure the solution is very simple but I just can't see it.

• Sharepoint Designer XSLT count boolean node = true

  - by Heather Masters

  I have a SharePoint list I converted to XSLT to do some additional grouping and counting and percentages. I need to return the number of items = true within my nodeset, I have: <xsl:value-of select="count($nodeset/@PartnerArrivedAtCall)"/> (which returns the count of all the nodes) I have tried <xsl:value-of select="count($nodeset/@PartnerArrivedAtCall [@PartnerArrivedAtCall = 'Yes'])"/> (returns zero) and <xsl:variable name="ArrivedYes" select="$nodeset/@PartnerArrivedAtCall [@PartnerArrivedAtCall='Yes']"/> (also returns zero) Can you please give me a good example of how to count only the true values (in my XML, true = "Yes") Thanks!

• What's the equivalent in C# of this VB code on an Outlook form?

  - by wes

  Basically, how do I link an Outlook form and a C# back end? In VB you can write on the form Sub ButtonName_Click() Dim Recipients With Item.GetInspector.ModifiedFormPages("Message") Set Recipients = .Controls("To") End With End Sub which will fire whenever the button named "ButtonName" on the form is clicked and will set the variable Recipients to a string of whatever is in the To text box. Now I have a custom form, and I have a VS C# Outlook Add-in, and they're two separate things. I've got an event handler that can catch MailItem objects, but I don't know how to handle custom form button clicks or even how to access elements on the form. EDIT - Just to clarify, the custom form was created in Outlook and then its .ofs was imported into VS. Both Outlook and VS are 2010.

• How do you get the ID of a control in ASP.NET

  - by James

  I am attempting to loop through an array of numbers, match them to the checkbox they they are associated with, and checkmark that box. My checkbox is set up like: <input type="checkbox" runat="server" id="someID" name="somename" value="1234" /> My code when the page loads currently looks like: foreach (string interest in interests_Var){ foreach (var c in Page.Controls) { } } interests_Var is my array containing different numbers. We'll assume one of them is 1234. While looping through the page controls, I want to compare the value of the control to my number. If it equals my number, I want to then apply the attribute checked="checked". I'm assuming I have to find the ID of the control I am using, then use that ID to add a new attribute. Or is there a way I can add the attribute using the c variable? I'm not dead set on this setup, so if you know a better way, I'm all ears. Thanks for any help and suggestions.

• What are the implications of using static const instead of #define?

  - by Simon Elliott

  gcc complains about this: #include <stdio.h> static const int YY = 1024; extern int main(int argc, char*argv[]) { static char x[YY]; } $ gcc -c test1.c test1.c: In function main': test1.c:5: error: storage size of x' isn't constant test1.c:5: error: size of variable `x' is too large Remove the “static” from the definition of x and all is well. I'm not exactly clear what's going on here: surely YY is constant? I had always assumed that the "static const" approach was preferable to "#define". Is there any way of using "static const" in this situation?

• Number range for color in GLSL

  - by kotoko

  I'm figuring out how to set a colour in a Fragment Shader. This statement gl_FragColor = (0.1,0.6,1,1); gives me white regardless of what I enter in the first 3 values. I was expecting to either give it values between 0 and 255 or 0 and 1 but neither seems to work. I can change how bright it is with values from 0 to 1 in the fourth value, but nothing for colour. Can anybody tell me if: gl_FragColor is the right variable to set. What is the range of values for the first three values. What am I currently making the Shader do.

• I have to generate PL/SQL using Java. Most of the procedures are common. Only a few keeps changing.

  - by blog

  I have to generate PL-SQL code, with some common code(invariable) and a variable code. I don't want to use any external tools. Some ways that I can think: Can I go and maintain the common code in a template and with markers, where my java code will generate code in the markers and generate a new file. Maintain the common code in static constant String and then generate the whole code in StringBuffer and at last write to file. But, I am not at all satisfied with both the ideas. Can you please suggest any better ways of doing this or the use of any design patterns or anything? Thanks in Advance.

• How do I remove specific numbers from a string?

  - by user1666900

  I have this string in PHP Hopelessly Incredible |SPG:M| 766 STEAM_0:1:20130600 " banned "A Blatantly Obvious Hacker 740 STEAM_0:1:55386073 " (minutes "0") (reason "Multi-Hack") The Format of the string is: Name1 Number(0-3 digits) Steam_0:x:xxxx offense (banned/kicked/mute etc) Name2 Number(0-3 digits) Steam_0:x:xxxx time reason My goal is to remove the values 766 and 740 because it is just garbage. Those values can have single, double, and triple digits. The next step would be to strip STEAM_0:1:20130600 and STEAM_0:1:55386073 out of the string and capture it in a new variable. The only constant is STEAM_0: the rest can change. I am still learning regex but I fear this is a bit complicated for me to do. Some guidance would be most appreciative.

• Why are my JavaScript variables not persisting across functions?

  - by Eric Belair

  I have the following JavaScript in my HTML page referencing an HTML form on the page: <script type="text/javascript"> <!-- var myForm = document.myForm; function validateForm() { if (myForm.myInput == "") alert("Please input some text."); return false; } myForm.submit(); } function showFormInput() { myForm.reset(); document.getElementById('myInput').style.display = 'inline'; } //--> </script> ... <form name="myForm" id="myForm" action="..." method="post"> <input id="myInput" name="myInput" type="text" value="" style="display:none;" /> </form> Both functions are throwing an exception when trying to access the variable myForm, saying that "myForm is null or not an object". Why is this occurring?

• JQuery post to php

  - by RussP

  Why is it that I can never get JQuery serialize to work properly. I guess I must be missing something. I can serialize a form data and it shows in an alert: var forminfo = $j('#frmuserinfo').serialize(); alert(forminfo); I then post to my PHP page thus: $j.ajax({ type: "POST", url: "cv-user-process.php", data: "forminfo="+forminfo, cache: false, complete: function(data) { } }); But WHENEVER (not the first time) I try to insert/update the data in the DB I only ever get 1 varaible passed: Here is my PHP script: $testit = mysql_query("UPDATE cv_usersmeta SET inputtest='".$_POST['forminfo']."' WHERE user='X'"); the data passed only ever gets the first variable. why? I think it is more the way I deal with the php but it drives me nuts and always takes me far too long to find where I am going wrong.

• C#: Convert array to use in params with additional parameters

  I have a method that takes params. Inside the method another variable shall be added to the output: private void ParamsTest(params object[] objs) { var foo = "hello"; // Invalid: Interpretes objs as single array parameter: Console.WriteLine("{0}, {1}, {2}", foo, objs); } When I call ParamsTest("Hi", "Ho"); I would like to see the output. hello Hi Ho What do I need to do?

  i'm trying to save 100 caracters form user in a 'microblog' minimal application. my code seems to not have any mystakes, but doesn't work. the mistake is in views.py, i can't save the foreign key to user table models.py looks like this: class NewManager(models.Manager): def create_post(self, post, username): new = self.model(post=post, created_by=username) new.save() return new class New(models.Model): post = models.CharField(max_length=120) date = models.DateTimeField(auto_now_add=True) created_by = models.ForeignKey(User, blank=True) objects = NewManager() class NewForm(ModelForm): class Meta: model = New fields = ['post'] # widgets = {'post': Textarea(attrs={'cols': 80, 'rows': 20}) def save_new(request): if request.method == 'POST': created_by = User.objects.get(created_by = user) date = request.POST.get('date', '') post = request.POST.get('post', '') new_obj = New(post=post, date=date, created_by=created_by) new_obj.save() return HttpResponseRedirect('/') else: form = NewForm() return render_to_response('news/new_form.html', {'form': form},context_instance=RequestContext(request)) i didn't mention imports here - they're done right, anyway. my mistake is in views.py, when i try to save it says: local variable 'created_by' referenced before assignment it i put created_py as a parameter, the save needs more parameters... it is really weird help please!!

• How to pass a value between Silverlight pages for WP7?

  - by Sebastian Gray

  I've got a MainPage.xaml page a Detail.xaml page. I've passed variables to the Detail.xaml from MainPage.xaml by using a static variable and referencing it in Detail.xaml (the detail page is acting like a dialog). However once I've updated the content of another object, I want to call a method in MainPage.xaml to refresh the content of that page using the updated object from the Detail.xaml page. I assume I am not using the correct paradigm for this and should probably be using MVVM or something but I'm not familiar with the implementation and was hoping there was a simple way to do this?

• c++ Array passing dilemma

  - by Thomas

  Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.
