• How do I generate (and label) a random integer with python 3.2?

  - by An hero

  Okay, so I'm admittedly a newbie to programming, but I can't determine how to get python v3.2 to generate a random positive integer between parameters I've given it. Just so you can understand the context, I'm trying to create a guessing-game where the user inputs parameters (say 1 to 50), and the computer generates a random number between the given numbers. The user would then have to guess the value that the computer has chosen. I've searched long and hard, but all of the solutions I can find only tell one how to get earlier versions of python to generate a random integer. As near as I can tell, v.3.2 changed how to generate and label a random integer. Anyone know how to do this? Thanks!

• Planning a competition

  - by Jérôme

  I need to produce the schedule of a sport-event. There are 30 teams. Each team has to play 8 matches. This means that it is not possible for each team to compete again all other teams, but I need to avoid that two team compete more than once against each other. My idea was to generate all possible matches (for 30 teams: (30*29)/2 = 435 matches) and select from this list 120 matches (8 match for each team: 8 * 30 / 2 = 120 matches). This is where I'm having a hard time: how can I select these 120 matches? I tried some simple solutions (take first match of the list, then the last, and so on) but they don't seem to work with 30 teams. I also tried to generate all possible match combination and find which one is working but with 30 team, this is too much calculation time. Is there an existing algorithm that I could implement?

• Problem with Juggernaut and transparent wmode in Adobe AIR

  - by vortexmk

  Hi, I am trying to use juggernaut in Adobe AIR application, however the big issue with this is that the juggernaut flash file should have wmode parameter set to 'transparent'. This is a bit of a problem for juggernaut because it seems that it doesn't work with that parameter included. The interesting part is that it is working under Linux on all browsers and in air application, but on Windows it's working only with Safari all other browsers including the AIR application are not even connecting to the juggernaut server. So the question is, what is the cause of this and if anyone had similar problem I would be interested to hear about solutions or workarounds. Thanks, Peco

• TextMate/Macfusion combo for mounting projects over SSH

  - by Sam Lee

  Here is my workflow: I use Macfusion to mount a server over SSH, and then edit the root directory of the project in TextMate (using mate /Volumes/server/projectdir). I have a plug in installed that disables refreshing on refresh. This works ALMOST perfectly--the only thing I have problems with is "Find in Project": it's REALLY slow. Has anyone run into this problem before and been able to find any solutions? Currently I go to terminal when I have to do a search, but it would be great to be able to do it in TextMate. Thanks!

• Can I use/include gsdll32.dll redmonnt.dll (no modifications) in a commercial application for my cli

  - by scriptmaster

  I am not a license expert; however, after a lot of research, I am still struggling to answer the following questions and would like to know if my assumptions are right! Is it legal to include gsdll32.dll and redmonnt.dll in a commercial product? Should I release any source code of the commercial app where I am using this library? Is there a commercial license (a small fee that my client can pay to use these libraries) to GhostScript? What are the alternative solutions?

• Edit PDF online and save and form data to server

  - by Clowerweb

  Hello, I have some PDF documents which are being displayed in the browser, with some fields already being pre-populated from the database using iTextSharp (we are running Windows Server 2008, IIS 7, SQL Server 2008, and ASP.NET 2.0/2.5 with C#). Our clients need to be able to fill in the remaining fields and save the PDF to the server. I have considered the following possibilities: 1.) Somehow using iTextSharp to parse the form fields, grab all the form data and save it to the database on submit. 2.) Adding a submit button to the PDF itself using LiveCycle with some sort of JS click event to save the FDF/XFDF/XDP/XML data either to the database or to a flat file on the server. I am currently unsure as to what the best approach would be, what would work, or how to implement any of these possible solutions, so any help would be greatly appreciated. Thanks!

• data structure for counting frequencies in a database table-like format

  - by user373312

  i was wondering if there is a data structure optimized to count frequencies against data that is stored in a database table-like format. for example, the data comes in a (comma) delimited format below. col1, col2, col3 x, a, green x, b, blue ... y, c, green now i simply want to count the frequency of col1=x or col1=x and col2=green. i have been storing the data in a database table, but in my profiling and from empirical observation, database connection is the bottle-neck. i have tried using in-memory database solutions too, and that works quite well; the only problem is memory requirements and quirky init/destroy calls. also, i work mainly with java, but have experience with .net, and was wondering if there was any api to work with "tabular" data in a linq way using java. any help is appreciated.

• What are some useful SQL statements / usage patterns that should be known by all developers who may

  - by Jian Lin

  What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?

• Zip Code to City/State and vice-versa in a database?

  - by Simucal

  I'm new to SQL and relational databases and I have what I would imagine is a common problem. I'm making a website and when each user submits a post they have to provide a location in either a zip code or a City/State. What is the best practice for handling this? Do I simply create a Zip Code and City and State table and query against them or are there ready made solutions for handling this? I'm using SQL Server 2005 if it makes a difference. I need to be able to retrieve a zip code given a city/state or I need to be able to spit out the city state given a zip code.

• JPA in distributed Java EE configuration

  - by sof

  Hello, I'm developing a JEE application to run on Glassfish: Database (javaDB, MS SQL, MySQL or Oracle) EJB layer with JPA (Toplink essentials - from Glassfish) for database access JSF/Icefaces based web UI accessing the EJB layer The application will have a lot of concurrent web client, so I want to run it on different physical servers and use a load-balancer. My problem is now how to keep the applications synchronized. I intend to set up multiple servers, each running Glassfish with my EAR app installed. Whenever on one of the servers data is added to or removed from the database (via JPA, no direct SQL queries), this change should be reflected in the JPA layer on the other servers. I've been looking around for solutions to this, but couldn't find anything I really like (the full Toplink from Oracle claims to have a solution, but don't know). Doing a refresh before every access to a JPA entity could work, but is far from efficient. Are there any patterns, libraries, ... that could help here? Thanks a lot!

• Framework Recommendation request: spring, struts, j2ee?

  - by Jack BeNimble

  The last time I looked at web applications, the consensus seemed to be Struts/J2EE. Now, it looks like Spring MVC/J2EE or Struts/J2EE are both viable solutions. Is this generally correct? Or is Spring MVC now the consensus choice over Struts? We have at least one guy who has worked with Struts before and wants to go with that. I'm more familiar with Struts as well, having reviewed in the past. Also, is J2EE still considered the viable solution for handling remote components? Or are there alternatives?

• Check if a string substitution rule will ever generate another string.

  - by Mgccl

  Given two strings S and T of same length. Given a set of replacement rules, that find substring A in S and replace it with string B. A and B have the same length. Is there a sequence of rule application, such that it make string S into string T? I believe there is no better way to answer this than try every single rule in every single state. Which would be exponential time. But I don't know if there are better solutions to it.

• How to get access under testing

  - by Friedrich

  This question is related to: http://stackoverflow.com/questions/3027705/experiences-with-language-converters I just can tell I searched the web for quite a few days but hardly found anything about somewhat "proper" test in access. I found some framworks like accessunit but that's Unit testing, what abouut the forms? What about the different reports etc. A counter-example in "testing" is e.g the rails or Seaside or Smalltalk area. Where testing is thought of as integral part. But I have not found anything comparable for Access based solutions. Maybe some of you know better?

• How to have favicon / icon set when bookmarklet dragged to toolbar?

  - by Pistos

  I've made myself a bookmarklet, and it functions just fine, but when added to a toolbar in Opera or Firefox, it just takes on the default bookmark icon for the browser (a globe and a star, respectively). My site has a favicon, and the window, tab and even [site] bookmark uses the favicon I've specified. Just not my bookmarklet. How can I code my site or bookmarklet so that the bookmarklet gets the favicon, too? I'm aware of various manual hackery techniques users can use to set the favicon after the fact, but those are undesirable solutions.

• Cannot move ckeditor 4 selection to beginning

  - by Gary Hillerson

  I've been exploring numerous solutions in stackoverflow and elsewhere to try to get ckeditor 4 to scroll to the top after I've programmatically added a number of pages to it, using CKEditor's InsertHtml function. After adding my html, which looks fine, I want to position the cursor at the beginning. Here's one of a variety of things I've tried without success: function MoveCaretToStart(myEditor) { var range = new CKEDITOR.dom.range( editor.document ); range.selectNodeContents(editor.document.getBody()); range.moveToElementEditStart(range.root); // also tried range.collapse(true); range.select(); } ... MoveCaretToStart(CKEDITOR.instances['myEditor']); // which already has contents in it This doesn't throw any errors, but also doesn't move the cursor position (it remains at the end of the doc). I thought this one would be easy, but it sure hasn't been. Any help appreciated.

• Are there any OSGi web service / SOAP clients out there?

  - by James Carr

  I'm looking for any webservice client that can be run inside an OSGi container and connect to a simple web service using SOAP, doesn't sound so hard does it? Oh, and it has to work under Java 1.5, so the JRE jax-ws wont be present. The problem is I've tried a few solutions now, and although each solution works in standard Java using it from within OSGi doesn't. the springsource JAX-WS bundles seem to have dependency issues the CXF bundles get me as far as calling the service, but then can seem to find the stub methods in the proxy Is there anyone out there who has successfully created an OSGi webservice client?

  I have a solution that was developed in VS 2008 that is configured to use IIS. I configure the Virtual directory in IIS the same way I have with other working solutions using IIS. When I either build and run the solution in VS 2008 or browse the virtual directory using IIS, I get the following error message. Internet Explorer cannot display the webpage What you can try: It appears you are not connected to the Internet, but you might want to try to reconnect to the Internet Retype the address Go back to the previous page. Most likely causes: You are not connected to the Internet The website is encountering problems There might be a typing error in the address. Why might this be?

• How to write a technical blog?

  - by Gutzofter

  I have a blog that I would like to increase traffic on. I've read lots of technical blogs, but it's a lot different writing a blog versus reading a blog. There seems to be several ways to write a post. General article: I like this tool. This is how I do it. Specific technical issue: Programming solutions. I do get some traffic, but they don't leave any comments. Should I use HN and Reddit. What are some of the other places I can promote my blog? How to respond to negative comments (trolls)? Another thing is you might want to have some link-thrus. comment on other peoples blog posts. BTW my blog is: (defun ugly-lisp-code () ()) New Blog ugly web development

• NASM: Count how many bits in a 32 Bit number are set to 1.

  - by citronas

  I have a 32 Bit number and want to count know how many bits are 1. I'm thinking of this pseudocode: mov eax, [number] while(eax != 0) { div eax, 2 if(edx == 1) { ecx++; } shr eax, 1 } Is there a more efficient way? I'm using NASM on a x86 processor. (I'm just beginning with assembler, so please do not tell me to use code from extern libraries, because I do not even know how to include them ;) ) (I just found http://stackoverflow.com/questions/109023/best-algorithm-to-count-the-number-of-set-bits-in-a-32-bit-integer which also contains my solution. There are other solutions posted, but unfortunatly I can't seem to figure out, how I would write them in assembler)

• Dash surrounding text

  - by Brandon Hansen

  Given the above dynamically generated text (meaning that I can't just use an image), I am trying to recreate the design using just html and css selectors. I would like to just use a single h4 with the containing text, but am open to other solutions. I would prefer to not use absolute positioning, but again, if that is the only way, then so be it. I have tried surrounding with span tags, but those are inline elements that don't have an inherent width. The h4 will be nested within a div, though not always of the same class or id. Any ideas or resources to get me started?

• Parse Domain from a given URL in T-SQL

  - by Adam N

  I fount this answer, but wanted to expand on the question and couldn't find any solutions here on stack or through searching google. Substring domainname from URL SQL Basically the link above solves my problem with a simple URL like parsing "www.google.com" with the result of google. What I am looking for to expand on that is the solution from the link above doesn't help with url's like 'www.maps.google.com' that just returns maps. WHat I would like is to have it return 'google' from the url 'www.maps.google.com' or return 'example' from 'www.test.example.com'. If anyone has a solution to this, I would greatly appreciate it. Update: To be more specific I will also need parsing on second level domains etc. 'www.maps.google.com.au' to return 'google' Here is my Sql function. CREATE FUNCTION [dbo].[parseURL] (@strURL varchar(1000)) RETURNS varchar(1000) AS BEGIN IF CHARINDEX('.', REPLACE(@strURL, 'www.','')) > 0 SELECT @strURL = LEFT(REPLACE(@strURL, 'www.',''), CHARINDEX('.',REPLACE(@strURL, 'www.',''))-1) Else SELECT @strURL = REPLACE(@strURL, 'www.','') RETURN @strURL END

• Find Date From Non Contiguous Ranges

  - by AGoodDisplayName

  I am looking to find an best way to find a date from date ranges that may or may not be contiguous (I am trying to avoid a cursor, or a heavy function if possible). Lets say I have hotel guests that come and go (check in, check out). I want to find the date that a certain guest stayed their 45th night with us. The database we use records the data as so: Create Table #GuestLog( ClientId int, StartDate DateTime, EndDate DateTime) Here is some data Insert Into #GuestLog Values(1, '01/01/2010', '01/10/2010') Insert Into #GuestLog Values(1, '01/16/2010', '01/29/2010') Insert Into #GuestLog Values(1, '02/13/2010', '02/26/2010') Insert Into #GuestLog Values(1, '04/05/2010', '06/01/2010') Insert Into #GuestLog Values(1, '07/01/2010', '07/21/2010') So far I can only think of solutions that involve functions with temp tables and crazy stuff like that, I feel like I'm over thinking it. Thanks ahead of time.

• Merging photo textures - (from calibrated cameras) - projected onto geometry

  - by freakTheMighty

  I am looking for papers/algorithms for merging projected textures onto geometry. To be more specific, given a set of fully calibrated cameras/photographs and geometry, how can we define a metric for choosing which photograph should be used to texture a given patch of the geometry. I can think of a few attributes one may seek minimize including the angle between the surface normal and the camera, the distance of the camera from the surface, as well as minimizing some parameterization of sharpness. The question is how do these things get combined and are there well established existing solutions?
