• Creating a project, from Makefile to static/dynamic libraries in UNIX

  - by Sasha

  Guys, would you describe a few things about c++ building blocks, on unix. I want to create an application that links against static libs and dynamic libs (.so). Question 1: How do I create static library using gcc/g++ ?How do I make my app link against it. Question 2: How to specify it in the makefile, linking against static and dynamic libs, assuming that both libraries have header files Summary: I have been using makefiles and libraries for years, written by someone else. Thus every time I modified it, I simply cut-and-pasted things around, without really understanding it. Now I want to get down to the ground and understand the building/linking/Creating Makfile process in-depth. What is a good book describing these concepts in intimate details? Thanks

• Top tips for designing GUIs?

  - by oxbow_lakes

  A while back I read (before I lost it) a great book called GUI Bloopers which was full of examples of bad GUI design but also full of useful tidbits like Don't call something a Dialog one minute and a Popup the next. What top tips would you give for designing/documenting a GUI? It would be particularly useful to hear about widgets you designed to cram readable information into as little screen real-estate as possible. I'm going to roll this off with one of my own: avoid trees (e.g. Swing's JTree) unless you really can't avoid it, or have a unbounded hierarchy of stuff. I have found that users don't find them intuitive and they are hard to navigate and filter. PS. I think this question differs from this one as I'm asking for generalist tips

• Regex gurus! here's a teaser: mixed thousands separators and csv's

  - by chichilatte

  I've got a string like... "labour 18909, liberals 12,365,conservatives 14,720" ...and i'd like a regex which can get rid of any thousands separators so i can pull out the numbers easily. Or even a regex which could give me a tidy array like: (labour => 18909, liberals => 12365, conservatives => 14720) Oh i wish i had the time to figure out regexes! Maybe i'll buy one as a toilet book, mmm.

• Storing DOM reference elements in Javascript array

  - by webzide

  Dear experts, I was trying to dynamically generate DOM elements using JS. I read from Douglas Crockford's book that DOM is very very poorly structured. Anyways, I would like to create a number of DIVISION elements and store the reference into an array so it could be accessed later. Here's the code for(i=0;i<3;i++){ var div=document.body.appendChild(document.createElement("div")); var arr=new Array(); arr.push(div); } Somehow this would not work..... There is only 1 div element created. When I use the arr.length to test the code there is only 1 element in the array. Is there another way to accomplish this. THanks in advance

• Tutorial for texture mapping a map onto an Open GL ES sphere?

  - by hotpaw2

  I'm not looking for a library or even open source code. I want to learn how to do this on my own. Where do I start to find an online tutorial, a book chapter, or other educational material for generating a polygonal model of a 3D sphere suitable for feeding to Open GL ES on an iPhone, and then mapping the polygons to some sort of 2D map data so I can texture map the sphere? Is there some sort of software tool (blenders? mayan?) with a tutorial on how to do generate this data? Where is the best place to start?

• Erlang on a JVM/CLR

  - by Fortyrunner

  I've just started reading Joe Armstrongs book on Erlang and listened to his excellent talk on Software Engineering Radio. Its an interesting language/system and one whose time seems to have come around with the advent of multi-core machines. My question is: what is there to stop it being ported to the JVM or CLR? I realise that both virtual machines aren't setup to run the lightweight processes that Erlang calls for - but couldn't these be simulated by threads? Could we see a lightweight or cutdown version of Erlang on a non Erlang VM?

• ruby on rails adding new route

  - by ohana

  i have an RoR application Log, which similar to the book store app, my logs_controller has all default action: index, show, update, create, delete.. now i need to add new action :toCSV, i defined it in logs_controller, and add new route in the config/routes as: map.resources :logs, :collection = { :toCSV = :get }. from irb, i checked the routes and see the new routes added already: rs = ActionController::Routing::Routes puts rs.routes GET /logs/toCSV(.:format)? {:controller="logs", :action="toCSV"} then ran ‘rake routes’ command in shell, it returned: toCSV_logs GET /logs/toCSV(.:format) {:controller="logs", :action="toCSV"} everything seems working. finally in my views code, i added the following: link_to 'Export to CSV', toCSV_logs_path when access it in the brower 'http://localhost:3000/logs/toCSV', it complained: Couldn't find Log with ID=toCSV i checked in script/server, and saw this one: ActiveRecord::RecordNotFound (Couldn't find Log with ID=toCSV): app/controllers/logs_controller.rb:290:in `show' seems when i click that link, it direct it to the action 'show' instead of 'toCSV', thus it took 'toCSV' as an id...anyone know why would this happen? and to fix it? Thanks...

• How can I manipulate the strip text of facet plots in ggplot2?

  - by briandk

  I'm wondering how I can manipulate the size of strip text in facetted plots. My question is similar to a question on plot titles, but I'm specifically concerned with manipulating not the plot title but the text that appears in facet titles (strip_h). As an example, consider the mpg dataset. library(ggplot2) qplot(hwy, cty, data = mpg) + facet_grid( . ~ manufacturer) The resulting output produces some facet titles that don't fit in the strip. I'm thinking there must be a way to use grid to deal with the strip text. But I'm still a novice and wasn't sure from the grid appendix in Hadley's book how, precisely, to do it. Also, I was afraid if I did it wrong it would break my washing machine, since I believe all technology is connected through The Force :-( Many thanks in advance.

• Signature of Collections.min/max method

  - by Marco

  In Java, the Collections class contains the following method: public static <T extends Object & Comparable<? super T>> T min(Collection<? extends T> c) Its signature is well-known for its advanced use of generics, so much that it is mentioned in the Java in a Nutshell book and in the official Sun Generics Tutorial. However, I could not find a convincing answer to the following question: Why is the formal parameter of type Collection<? extends T>, rather than Collection<T>? What's the added benefit?

• PHP complete sample website source

  - by MarceloRamires

  I'm new to PHP, and it appears that the way I learn the fastest is to study a new language a well developed complete program (or website, in this case) changing stuff seeing what happens and consulting books. There are lots of recommendations of books all around, and that's pretty much covered. I'd like to find the sourcecode of a website. Either a well known, well developed open-source website, or a sample sourcecode of a complete website (maybe one used in a book or something). Everyone says they should find the way they learn better.. Well, that's mine. PS.: By complete I mean having several common functionalities (such as login), database connection, use of security conventions, maybe a popular framework, and being up-to-date.

• Examples of ISO C++ code that is not valid C++/CLI

  - by Johannes Schaub - litb

  I've seen contradictory answers on the internet with regard to whether C++/CLI is a superset of C++ or not. The accepted answer on this question claims that "technically no", but doesn't provide an examples of non-C++/CLI code that conforms to ISO C++. Another answer on that question cites a book that says the opposite. So, can you please provide accurate answers with example code that fails on C++/CLI or cite a trusted source (MSDN for example) on this matter? I had someone this topic come up today and thought I would like to inform myself, but I didn't find any clear answer elsewhere!

• Git + Capistrano = Automatic Release Notes Generator ?

  - by Matt Rogish

  We use git (github) and capistrano (like 99% of the Rails shops out there) to deploy our app to production. What I'd like to do is, after every cap * deploy generate a text file containing all the git commit comments since the last deploy. I can then take that list of commit comments, clean it up, and put it somewhere for consumption. "git log" http://book.git-scm.com/3_reviewing_history_-_git_log.html has plenty of options for fetching log messages, but I don't see an easy way in capistrano to return the current and previous commits, or even the last date/time a deployment occurred, so I can pass that to git log Thoughts? I can't be the first one doing this... Thanks!

• What are the uses of svn copy?

  - by nav.jdwdw

  Example: $ svn copy foo.txt bar.txt A bar.txt When would you use this technique, and why? Will this command (taken from svn's "red book") creates a copy of <foo.txt> while preserving the history of it to be shared with <bar.txt>? If I'm changing <bar.txt>, what will happen to <foo.txt>? What are the equivalents to this in other modern systems (Clearcase, Accurev, Perforce)? Clarification: Let me emphasize the point I'm searching for: Is this kind of branching out on a file level? What happens if you use it in the same branch, i.e. create a copy of a file and than start changing that new file. all in the same branch? I understand that it is also used for tagging but what is interesting me is what to expect when performing <svn copy> On the file level

• StringBuilder/StringBuffer vs. "+" Operator

  - by matt.seil

  I'm reading "Better, Faster, Lighter Java" (by Bruce Tate and Justin Gehtland) and am familiar with the readability requirements in agile type teams, such as what Robert Martin discusses in his clean coding books. On the team I'm on now, I've been told explicitly not to use the "+" operator because it creates extra (and unnecessary) string objects during runtime. But this article: http://www.ibm.com/developerworks/java/library/j-jtp01274.html Written back in '04 talks about how object allocation is about 10 machine instructions. (essentially free) It also talks about how the GC also helps to reduce costs in this environment. What is the actual performance tradeoffs between using "+," "StringBuilder," or "StringBuffer?" (In my case it is StringBuffer only as we are limited to Java 1.4.2.) StringBuffer to me results in ugly, less readable code, as a couple of examples in Tate's book demonstrates. And StringBuffer is thread-synchronized which seems to have its own costs that outweigh the "danger" in using the "+" operator. Thoughts/Opinions?

• Analysis Services with excel as front end - is it possible to get the nicer UI that powerpivot provi

  - by AJM

  I have been looking into PowerPivot and concluded that for "self service BI" and ahoc buidling of cubes it has its uses. In particular I like the enhanced UI that you get from using PowerPivot rather than just using a PivotTable hooked up to an analysis services datasource. However it seems that hooking up PowerPivot to an existing analysis services cube is not a solution for "organisational BI". It is not always desireable to suck millions of rows into excel at once and the interface between PowerPivot and analysis services is very poor in my book. Hence the question is can an existing analysis services solution get the enhanced ui features that power pivot brings, withoout using powerpivot as the design tool? If powerpivot is aimed ad self service/personal BI then it seems bizare that the UI for this is better than for bigger/more costly analysis services solutions.

• "Circuit breaker" for net.msmq?

  - by Alex

  Hi, The Circuit Breaker pattern, from the book Release It!, protects a service from requests while it is failing (or recovering). The net.msmq binding used with transactions give us nice retry and poison message capabilities. But I am missing the implementation of such a "Circuit breaker" pattern. A service is put under even heavier load by retries while it is already in a failure condition (like DB connectivity issues causing loads of blocked threads etc.). Anyone knows about a behavior extension or similar that explicitly closes the service host when defined failure thresholds have been exceeded? Cheers, Alex

• How to build Object Oriented Skills?

  - by cedar715

  Being a core developer for couple of years, coding applications seeing the class diagrams, sequence diagrams, I decided to improve my self, taking the next step of designing. As I'm an OO developer, I'm interested in improving my design skills. For Example, I had a hard time designing a currency converter. My questions to the SO: Is it by experience the design skills can be acquired? Will learning books/blog/material over internet etc help? Is it that one needs the domain knowledge of the application being developed? Knowing Design patterns, principles? Studying 'Code Complete' book ? Need to have Problem-solving skills? In short, given a problem, I just want to solve it in Object-oriented way??

• Looking to eventually build a smartphone app...

  - by Brian L

  Hi all- I'm a young, inexperienced programmer (I've had a year of Java, some MATLAB, and HTML/CSS in school) but I've decided that to get better, I'm making it my goal to produce a simple smartphone app of some kind this year- probably either webOS or Android since I'm on a PC and can't afford a Mac just to write an iPhone app. So my question is, where do I start? I've read the threads about How to Write for Android and such, but I'm not sure I have enough Java experience to just jump right in. And then there's webOS which is based on JavaScript, correct? I guess I'd just like some input from more experienced folks. I have some Barnes and Noble book credit I'm looking to get rid of too, so if there's a guide you think would be useful, feel free to request. tl;dr: Programming newbie ultimately wants to build a simple smartphone app. Where do I start?

• Spring/EJB 3 books?

  - by Zenzen

  Ok so I'm a complete beginner when it comes to Spring and EJB and I really want to change it, the problem is I can't find any single book on Spring 3/EJB 3, everything is about 2 (for Spring/EJB) or 2.5 (for Spring). What are the differences between 2.x and 3? Should I just go with the 2.x books and then google the differences? I was thinking about getting Pro Spring 2.5 from Apress and Head First EJB (huge fan, ut from what I've heard it is rather out of date), or are there better positions?

• Learning how to program real things.

  - by Sean

  How would you guys recommend I actually learn to program real things? I mean, I know how to do basic academic things. I can implement a templated stack/queue/map/etc. data structure in C++ or Java or whatever. I can make a text-based hangman game or whatever. Etc etc. But how can I learn to program something real, something useful? I've done project Euler up to question 100 or so, and I feel like that's given me more mathematical maturity but not programming maturity. Should I buy a book and follow exercises, struggle through interesting projects, etc, ? In short, how did you guys transition from academic exercises to real, fun and/or useful programs?

• Nesting maximum amount of shapes on a surface

  - by Fuu

  In industry, there is often a problem where you need to calculate the most efficient use of material, be it fabric, wood, metal etc. So the starting point is X amount of shapes of given dimensions, made out of polygons and/or curved lines, and target is another polygon of given dimensions. I assume many of the current CAM suites implement this, but having no experience using them or of their internals, what kind of computational algorithm is used to find the most efficient use of space? Can someone point me to a book or other reference that discusses this topic?

• Perls Of Wisdom For a .Net Programmer [closed]

  - by DeanMc

  Hi Guys, I like to think that recently I have moved from complete beginner to beginner. It has been a hard road and one on which I took many wrong turns. Very rarely in any profession is there a place where so many rock stars gather, this is something I would like to take advantage of. What I would like to ask is what are your perls of wisdom for a .net programmer. They can be anything you feel of value, a concept, a book, a process that should be followed, anything of that nature, it doesn't have to be .net specific just contextual. Thanks for taking the time to read this and respond.

• Parallel Assignment operator in Ruby

  - by Bragaadeesh

  Hi, I was going through an example from Programming in Ruby book. This is that example def fib_up_to(max) i1, i2 = 1, 1 # parallel assignment (i1 = 1 and i2 = 1) while i1 <= max yield i1 i1, i2 = i2, i1+i2 end end fib_up_to(100) {|f| print f, " " } The above program simply prints the fibonacci numbers upto 100. Thats fine. My question here is when i replace the parallel assignment with something like this, i1 = i2 i2 = i1+i2 I am not getting the desired output. My question here is, is it advisable to use parallel assignments? (I come from Java background and it feels really wierd to see this type of assignment) One more doubt is : Is parallel assignment an operator?? Thanks
