• Python IDLE freezes

  - by ooboo

  This is absolutely frustrating, but I am not sure if the following is an issue only on my machine or with IDLE in general. When attempting to print a long list in the shell, and that could happen by accident while debugging, the program crushes and you have to restart it manually. Even worse, if you have a few editor windows open, it always spawns a few sub-processes, and each of these has to be manually shut down from the task manager. Is there any way to avoid that? I am using Python 3, by the way.

• stuck in while loop python

  - by user1717330

  I am creating a chat server in python and got quite far as a noob in the language. I am having 1 problem at the moment which I want to solve before I go further, but I cannot seem to find how to get the problem solved. It is about a while loop that continues.. in the below code is where it goes wrong while 1: try: data = self.channel.recv ( 1024 ) print "Message from client: ", data if "exit" in data: self.channel.send("You have closed youre connection.\n") break except KeyboardInterrupt: break except: raise When this piece of code get executed, on my client I need to enter "exit" to quit the connection. This works as a charm, but when I use CTRL+C to exit the connection, my server prints "Message from client: " a couple of thousand times. where am I going wrong?

• More efficient way to find & tar millions of files

  - by Stu Thompson

  I've got a job running on my server at the command line prompt for a two days now: find data/ -name filepattern-*2009* -exec tar uf 2008.tar {} ; It is taking forever, and then some. Yes, there are millions of files in the target directory. But just running... find data/ -name filepattern-*2009* -print > filesOfInterest.txt ...takes only two hours or so. At the rate my job is running, it won't be finished for a couple of weeks.. That seems unreasonable. Is there a more efficient to do this? Maybe with a more complicated bash script? A secondary questions is "why is my current approach so slow?"

• Ruby on Rails - Send JavaScript to view

  - by Eef

  Hey, I am creating a website in Ruby on Rails. I have a controller action that renders a view like so: def show time_left = Time.now.to_i - 3.hours.to_i @character = current_user.characters.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @character } end end This is fine as it renders the show.html.erb as I like. I would like however to somehow pass time_left to the view as a Javascript variable as this value is use by a countdown JQuery plugin. I could put a javascript block on the page in the HTML and print a instance variable out like so: <script type="javascript"> $('#countdown').countdown('<%= @time_left =>')</script> But I would like to keep all my JS in a external file and off the page could anyone give some advice on how to implement this? Cheers Eef

• Writing shorter code/algorithms, is more efficient (performance)?

  - by Carlos

  After coming across the code golf trivia around the site it is obvious people try to find ways to write code and algorithms as short as the possibly can in terms of characters, lines and total size, even if that means writing something like: n=input() while n>1:n=(n/2,n*3+1)[n%2];print n So as a beginner I start to wonder whether size actually matters :D. It is obviously a very subjective question highly dependent on the actual code being used, but what is the rule of thumb in the real world. In the case that size wont matter, how come then we don't focus more on performance rather than size?

• Custom tag with the logic in JSP (interprets JSPs with the passed parameters)

  - by Romario

  I want to create a custom jsp tag. I want this tag to take a jsp file as a parameter, and in this jsp I want to write the whole logic of the tag. Let's say I want to pass a collection to a tag and then I would write code in jsp to iterate the collection and display it in . Why I want to do it - I really hate having out.print() in my code. Is something like this feasible? I remember doing something similar a while ago, I just forgot the details and my search doesn't seem to find relevant info - a link to a good implementation of the would be nice.

• inet_ntoa problem

  - by codingfreak

  Hi I am declaring following variables unsigned long dstAddr; unsigned long gateWay; unsigned long mask; These variables contains ipaddresses in network byte order. So when I am trying to print them using inet_ntoa function for mask variable sometimes it is printing strange values printf("%s\t%s\t%s\t",inet_ntoa(dstAddr),inet_ntoa(gateWay),inet_ntoa(mask)); 192.168.122.0 0.0.0.0 0.255.255.255 but it should be 192.168.122.0 0.0.0.0 255.255.255.0 So is this because of inet_ntoa ??

• Python Profiling In Windows, How do you ignore Builtin Functions

  - by Tim McJilton

  I have not been capable of finding this anywhere online. I was looking to find out using a profiler how to better optimize my code, and when sorting by which functions use up the most time cumulatively, things like str(), print, and other similar widely used functions eat up much of the profile. What is the best way to profile a python program to get the user-defined functions only to see what areas of their code they can optimize? I hope that makes sense, any light you can shed on this subject would be very appreciated.

• Perl code -need some understanding.

  - by benjamin button

  Hi i have a perl code below: foreach (@tmp_cycledef) { chomp; my ($cycle_code, $close_day, $first_date) = split(/\|/, $_,3); $cycle_code =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; $close_day =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; $first_date =~ s/^\s*(\S*(?:\s+\S+)*)\s*$/$1/; #print "$cycle_code, $close_day, $first_date\n"; $cycledef{$cycle_code} = [ $close_day, split(/-/,$first_date) ]; } the value of tmp_cycledef comes from output of an sql query: select cycle_code,cycle_close_day,to_char(cycle_first_date,'YYYY-MM-DD') from cycle_definition d order by cycle_code; can anybody tell me what exactly is happening inside the for loop? thanks in advance.

• How can I generate a list of words made up of combinations of three word lists in Perl?

  - by Chris Denman

  I have three lists of words. I would like to generate a single list of all the combinations of words from the three lists. List 1: red green blue List 2: one two List 3: apple banana The final list would like like so: red one apple red two apple red one banana red two banana ... and so on Ideally I'd like to pass in three arrays and the routine return one array. I have done a simple loop like so: foreach $word1 (@list1){ foreach $word2 (@list2){ foreach $word3 (@list3){ print "$word1 $word2 $word3\n"; } } } However, this doesn't work if there's nothing in the second or third list (I may only want to iterate between one, two or three lists at a time - in other words, if I only supply two lists it should iterate between those two lists).

• How can I do printing in Java with layouts instead of low level coordinates?

  - by Jonas

  I need to to some printing from my Java Swing application. I have tried to use Java Tutorials, but everything is very low level, and time-consuming. I have to specify the coordinates for every line that I want to print. It it also very lowlevel to use text, because I have to use FontMetrics and calculate what space all text fills up. Is there any easier way to to printing in Java? I would like to design the documents with something like layout managers instead. Any good library or API?

• Fastest way to find the closest point to a given point in 3D, in Python.

  - by Saebin

  So lets say I have 10,000 points in A and 10,000 points in B and want to find out the closest point in A for every B point. Currently, I simply loop through every point in B and A to find which one is closest in distance. ie. B = [(.5, 1, 1), (1, .1, 1), (1, 1, .2)] A = [(1, 1, .3), (1, 0, 1), (.4, 1, 1)] C = {} for bp in B: closestDist = -1 for ap in A: dist = sum(((bp[0]-ap[0])**2, (bp[1]-ap[1])**2, (bp[2]-ap[2])**2)) if(closestDist > dist or closestDist == -1): C[bp] = ap closestDist = dist print C However, I am sure there is a faster way to do this... any ideas?

• Perl to output processed XML file encoded as UTF-8 with UNIX line endings (in Win32 environment)?

  - by Umber Ferrule

  Running ActiveState Perl 5.8.8 on WinXP. As the title suggests, I'd like to output an XML file as UTF-8 with UNIX line endings. I've looked at the PerlDoc for binmode, but am unsure of the exact syntax (if I'm not barking up the wrong tree). The following doesn't do it (forgive my Perl - it's a learning process!): sub SaveFile { my($FileName, $Contents) = @_; my $File = "SAVE"; unless( open($File, ">:utf-8 :unix", $FileName) ) { die("Cannot open $FileName"); } print $File @$Contents; close($File); } Any suggestions? Thanks.

  I am connecting to MySQL database on my webpage and have this copy-pasted code for errors: if(DB::isError($db)) die($db->getMessage()); I have the connection code in an outside file called connection.inc that I include at the beginning of my page before the DOCTYPE and html tags. For debugging purposes, how can I print the database errors on my webpage? I thought I could do something like this: echo 'Could not connect to database. The error was:' . $db->getMessage(); but this returns: Fatal error: Call to undefined method DB_mysql::getMessage()

• Organizing a random list of objects in Python.

  - by Saebin

  So I have a list that I want to convert to a list that contains a list for each group of objects. ie ['objA.attr1', 'objC', 'objA.attr55', 'objB.attr4'] would return [['objA.attr1', 'objA.attr55'], ['objC'], ['objB.attr4']] currently this is what I use: givenList = ['a.attr1', 'b', 'a.attr55', 'c.attr4'] trgList = [] objNames = [] for val in givenList: obj = val.split('.')[0] if obj in objNames: id = objNames.index(obj) trgList[id].append(val) else: objNames.append(obj) trgList.append([val]) #print trgList It seems to run a decent speed when the original list has around 100,000 ids... but I am curious if there is a better way to do this. Order of the objects or attributes does not matter. Any ideas?

• How can I create a custom cleanup mode for git?

  - by Danny

  Git's default cleanup of strip removes all lines starting with a # character. Unfortunately, the Trac engine's wiki formatter uses hashes in the beginning of a code block to denote the syntax type. Additionally any code added verbatim might include hashes as they are a common comment prefix; Perl comes to mind. In the following example the comments all get destroyed by git's cleanup mode. Example: {{{ #!/usr/bin/perl use strict; # say hi to the user. print "hello world\n"; }}} I'd like to use a custom filter that removes all lines beginning with a hash from the bottom of the file upwards. Leaving those lines that being with a hash that are embedded in the commit message I wrote alone. Where or how can I specify this in git? Note, creating a sed or perl script to perform the operation is not a problem, just knowing where to hook it into git is the question.

• IE8 + Jquery ajax call giving parsererror from dJango : for json data which seems valid in Firefox

  - by PlanetUnknown

  The ajax call works fine in FF. the data returned is in JSON here is an example from FF firebug - {"noProfiles": "No profiles have been created, lets start now !"} When I try to print the error in IE8 (& in compatibility modes as well), it says "parsererror". But the output seems to be valid JSON. Here is the ajax function call I'm making. Any pointers would be great ! $.ajax({ type: "GET", url: "/get_all_profile_details/", data: "", dataType: "json", beforeSend: function() {alert("before send called");}, success: function(jsonData) { alert("data received"); }, error: function(xhr, txt, err){ alert("xhr: " + xhr + "\n textStatus: " + txt + "\n errorThrown: " + err); } }); The alerts in the error function above give - xhr:<blank> textstatus:parsererror errorThrown: undefined Any pointers would be great ! Note : jquery : 1.3.2
