• Cocoa: Creating a Window with a Variable Number of Interface Elements

  - by Rui Pacheco

  Hi, I've a window that will have an unknown amount of text fields, determined by the content of a remote server. In high level terms, how should I go about this? Create a custom view or create an empty window with a backing NSWindowController and then add stuff to it when the window is opened? I've seen the examples on the O'Reilly Cocoa book and those effectively create a custom NSView. Is this the right way to do it, 8 year later?

• Are there any good programs for actionscript/flex that'll count lines of code, number of functions,

  - by onekidney

  Doug McCune had created something that was exactly what I needed (http://dougmccune.com/blog/2007/05/10/analyze-your-actionscript-code-with-this-apollo-app/) but alas - it was for AIR beta 2. I just would like some tool that I can run that would provide some decent metrics...any idea's?

• Reduce number of points in line

  - by culebrón

  I'm searching for algorithms to reduce the LOD of polylines, lines (looped or not) of nodes. In simple words, I want to take hi-resolution coastline data and be able to reduce its LOD hundred- or thousandfold to render it in small-scale. I found polygon reduction algorithms (but they require triangles) and Laplacian smoothing, but that doesn't seem exactly what I need.

• keep duplicate number records only - perl

  - by manu

  Hello I have one text string which is having some duplicate characters (FFGGHHJKL), these can be made unique by using the positive lookahead [perl script for the same$ perl -pe 's/(.)(?=.*?\1)//g']. (FFEEDDCCGG OUTPUT == FEDCG) My question is how to make it work on the numbers (Ex. 212 212 43 43 5689 6689 5689 71 81 === output should be 212 43 5689 6689 71 81) ? Also if we want to have only duplicate records to be given as the output from a file having n rows (212 212 43 43 5689 6689 5689 71 81 \n 66 66 67 68 69 69 69 71 71 52 ..\n .. .. \n... OUTPUT == 212 212 43 43 5689 5689 \n 66 66 69 69 69 71 71) then what should be done ? Thanks and regards -manu

• Minimizing the number of boxes that cover a given set of intervals

  - by fortran

  Hi, this is a question for the algorithms gurus out there :-) Let S be a set of intervals of the natural numbers that might overlap and b a box size. Assume that for each interval, the range is strictly less than b. I want to find the minimum set of intervals of size b (let's call it M) so all the intervals in S are contained in the intervals of M. Trivial example: S = {[1..4], [2..7], [3..5], [8..15], [9..13]} b = 10 M = {[1..10], [8..18]} // so ([1..4], [2..7], [3..5]) are inside [1..10] and ([8..15], [9..13]) are inside [8..18] I think a greedy algorithm might not work always, so if anybody knows of a solution of this problem (or a similar one that can be converted into), that would be great. Thanks!

• Puting contact number into field

  - by dfilkovi

  I have this code that has one button that let's me choose an entry from contacts, and passes that choesn contact to onActivityResult function. My question is how do I select data of that single contact when all that is passed is an Intent in data variable. That data variable, if converted to string shows something like "dat: content://contacts/people/4" so I see that selected contact is somehow passed, but what now? How to get that data? And also all I found by googling was examples with deprecated class People, so I don't know how too use new classes. Please help. Thank you. public class HelloAndroid extends Activity { private static final int CONTACT_ACTIVITY = 100; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Button contactButton = (Button) findViewById(R.id.pick_contact_button); contactButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { Uri uri = Uri.parse("content://contacts/people"); Intent contacts_intent = new Intent(Intent.ACTION_PICK, uri); startActivityForResult(contacts_intent, CONTACT_ACTIVITY); } }); } public void onActivityResult(int requestCode, int resultCode, Intent data){ super.onActivityResult(requestCode, resultCode, data); switch(requestCode){ case(CONTACT_ACTIVITY): { if(resultCode == Activity.RESULT_OK) { alertText(data.toString()); } break; } } } }

• Template metaprogram converting type to unique number

  - by daramarak

  I just started playing with metaprogramming and I am working on different tasks just to explore the domain. One of these was to generate a unique integer and map it to type, like below: int myInt = TypeInt<AClass>::value; I want to know if this is at all possible, and in that case how. Because although I have learned much about exploring this subject I still have failed to come up with an answer. (P.S. A yes/no answer is much more gratifying than a c++ solution that doesn't use metaprogramming, as this is the domain that I am exploring)

• How can a large number of developers write software together without either a cumbersome process or

  - by Mark Robinson

  I work at a company with hundreds of people writing software for essentially the same product. The quality of the software has to be high because so many people depend on it (not least the developers themselves). Because of this every major issue has resulted in a new check - either automated or manual. As a result the process of delivering software is becoming ever more burdensome. So that requires more developers which... well you can see it is a vicious circle. We now have a problem with releasing software quickly - the lead time even to change one line of code for a very serious issue is at least one day. What techniques do you use to speed up the delivery of software in a large organization, while still maintaining software quality?

• Generating lognormally distributed random number from mean, coeff of variation

  - by Richie Cotton

  Most functions for generating lognormally distributed random numbers take the mean and standard deviation of the associated normal distribution as parameters. My problem is that I only know the mean and the coefficient of variation of the lognormal distribution. It is reasonably straight forward to derive the parameters I need for the standard functions from what I have: If mu and sigma are the mean and standard deviation of the associated normal distribution, we know that coeffOfVar^2 = variance / mean^2 = (exp(sigma^2) - 1) * exp(2*mu + sigma^2) / exp(mu + sigma^2/2)^2 = exp(sigma^2) - 1 We can rearrange this to sigma = sqrt(log(coeffOfVar^2 + 1)) We also know that mean = exp(mu + sigma^2/2) This rearranges to mu = log(mean) - sigma^2/2 Here's my R implementation rlnorm0 <- function(mean, coeffOfVar, n = 1e6) { sigma <- sqrt(log(coeffOfVar^2 + 1)) mu <- log(mean) - sigma^2 / 2 rlnorm(n, mu, sigma) } It works okay for small coefficients of variation r1 <- rlnorm0(2, 0.5) mean(r1) # 2.000095 sd(r1) / mean(r1) # 0.4998437 But not for larger values r2 <- rlnorm0(2, 50) mean(r2) # 2.048509 sd(r2) / mean(r2) # 68.55871 To check that it wasn't an R-specific issue, I reimplemented it in MATLAB. (Uses stats toolbox.) function y = lognrnd0(mean, coeffOfVar, sizeOut) if nargin < 3 || isempty(sizeOut) sizeOut = [1e6 1]; end sigma = sqrt(log(coeffOfVar.^2 + 1)); mu = log(mean) - sigma.^2 ./ 2; y = lognrnd(mu, sigma, sizeOut); end r1 = lognrnd0(2, 0.5); mean(r1) % 2.0013 std(r1) ./ mean(r1) % 0.5008 r2 = lognrnd0(2, 50); mean(r2) % 1.9611 std(r2) ./ mean(r2) % 22.61 Same problem. The question is, why is this happening? Is it just that the standard deviation is not robust when the variation is that wide? Or have a screwed up somewhere?

• Adding an IList item to a particular index number

  - by Dr. Zim

  Our Client's database returns a set of prices in an array, but they sometimes don't include all prices, i.e., they have missing elements in their array. We return what we find as an IList, which works great when we retrieve content from the database. However, we are having difficulties setting the elements in the proper position in the array. Is it possible to create an IList then add an element at a particular position in the IList? var myList = new List<Model>(); var myModel = new Model(); myList[3] = myModel; // Something like what we would want to do

• XSLT workflow with variable number of source files

  - by chiborg

  I have a bunch of XML files with a fixed, country-based naming schema: report_en.xml, report_de.xml, report_fr.xml, etc. Now I want to write an XSLT style sheet that reads each of these files via the document() XPath function, extracts some values and generates one XML files with a summary. My question is: How can I iterate over the source files without knowing the exact names of the files I will process? At the moment I'm planning to generate an auxiliary XML file that holds all the file names and use the auxiliary XML file in my stylesheet to iterate. The the file list will be generated with a small PHP or bash script. Are there better alternatives? I am aware of XProc, but investing much time into it is not an option for me at the moment. Maybe someone can post an XProc solution. Preferably the solution includes workflow steps where the reports are downloaded as HTML and tidied up :) I will be using Saxon as my XSLT processor, so if there are Saxon-specific extensions I can use, these would also be OK.

• Limiting the maximum number of concurrent requests django/apache

  - by Johan

  Hi, I have a django site that demonstrates the usage of a tool. One of my views takes a file as input and runs some fairly heavy computation trough an external python script and returns some output to the user. The tool runs fast enough to return the output in the same request though. I would however want to limit how many concurrent requests to this URL/view to keep the server from getting congested. Any tips on how i would go about doing this? The page in itself is very simple and the usage will be low.

• how to number t-rows ,when table generated using nested forloop in django templates

  - by stackover

  Hi, This part is from views.py results=[(A,[stuObj1,stuObj2,stuObj3]),(B,[stuObj4,stuObj5,stuObj6]),(C,[stuObj7,stuObj8])] for tup in results: total = tot+len(tup[1]) render_to_response(url,{'results':res , 'total':str(tot),}) this is template code: <th class="name">Name</th> <th class="id">Student ID</th> <th class="grade">Grade</th> {% for tup in results %} {% for student in tup|last %} {% with forloop.parentloop.counter as parentid%} {% with forloop.counter as centerid%} <tbody class="results-body"> <tr> <td>{{student.fname|lower|capfirst}} {{student.lname|lower|capfirst}}</td> <td>{{student.id}}</td> <td>{{tup|first}}</td> </tr> {% endfor %} {% endfor %} Now the problems am having are 1. numbering the rows. Here my problem is am not sure if i can do things like total=total-1 in the templates to get the numbered rows like <td>{{total}}</td> 2.applying css to tr:ever or odd. Whats happening in this case is everytime the loop is running the odd/even ordering is lost. these seems related problems. Any ideas would be great :)

• Query Only Specified Number Of Items From Parent/Child Categories

  - by RogeR

  I'm having trouble figureing out how to query every item in a certain category and only list the newest 10 items by date. Here is my table layout: download_categories category_id (int) primary key title (var_char) parent_id (int) downloads id (int) primary key title (var_char) category_id (int) date (date) I need to query every file in a main category that lets say has 100 items and 5 child categories and only spit out the last 10 added. I have functions right now that just add up all the files so I can get a count by category, but I can't seem to modify the code to only display a certain amount of items based on the date.

• Encrypt text using a number

  - by Adam Matan

  Project Euler I have recently begun to solve some of the Project Euler riddles. I found the discussion forum in the site a bit frustrating (most of the discussions are closed and poorly-threaded), So I have decided to publish my Python solutions on launchpad for discussion. The problem is that it seems quite unethical to publish these solutions, as it would let other people gain reputation without doing the programming work, which the site deeply discourages. My Encryption problem I want to encrypt my answers so that only those who have already solved the riddles can see my code. The logical key would be the answer to the riddle, which is always numeric. In order to prevent brute-force attacks on my answers, I want to find an encryption algorithm that takes a significantly long time (few seconds) to run. Do you know any such algorithm? I would fancy a Python package, which I can attach to the code, over an external program that might have portability issues. Thanks, Adam

• How to write a large number of nested records in JSON with Python

The data records cannot be added by hand as there are very many.
