  • Code reading: where can i read great, modern, and well-documented C++ code?

    - by baol
    Reading code is one of the best ways to learn new idioms, tricks, and techniques. Sadly it's very common to find badly written C++ code. Some use C++ as it was C, others as if it was Java, some just shoot in their feet. I believe gtkmm is a good example of C++ design, but a binding could not be the better code to read (you need to know the C library behind that). Boost libraries (at least the one I read) tend to be less readable than I'd like. Can you mention open source projects (or other projects which source is freely readable) that are good example of readable, modern, well-documented, and auto-contained, C++ code to learn from? (I believe that one project per answer will be better, and I'd include the motivation that led you to selecting that one.)

  • Is Microsoft's Ribbon UI really that great, from a usability perspective?

    - by Thomas Owens
    The first time I ever used it was at my current job. Among my coworkers, the feelings toward it for usability are mixed. The other developer doesn't really care one way or the other, as long as Office does everything he needs it to do when writing reports. The top manager likes it because it feels natural, and I feel the same way. But another coworker finds in klunky and hard to use (although she admits that she only uses it at home as her machine hasn't been upgraded yet, and that might change if she uses it more often at work). So - is the Ribbon UI really that innovative? What qualities about it make it a good or bad user interface mechanism? Possibly related: Adoption of the Ribbon UI

  • What should I tell kids about how great it is to be a programmer?

    - by Sara Chipps
    I am putting a presentation together. I thought about illustrating with websites like Facebook, and MySpace. Does anyone have children around that age that could tell me what they are into? How to hold their attention? Ways to illustrate what we do? Get them interested? Your ideas are greatly appreciated, I really want to be able to convey how fun this is :). I don't have access to a digital projector... which really stinks. I do have access to an old transparency overhead, though. http://stackoverflow.com/questions/207278/career-day-how-do-i-make-computer-programmer-sound-cool-to-8-year-olds

  • Anyone Know a Great Sparse One Dimensional Array Library in Python?

    - by TheJacobTaylor
    I am working on an algorithm in Python that uses arrays heavily. The arrays are typically sparse and are read from and written to constantly. I am currently using relatively large native arrays and the performance is good but the memory usage is high (as expected). I would like to be able to have the array implementation not waste space for values that are not used and allow an index offset other than zero. As an example, if my numbers start at 1,000,000 I would like to be able to index my array starting at 1,000,000 and not be required to waste memory with a million unused values. Array reads and writes needs to be fast. Expanding into new territory can be a small delay but reads and writes should be O(1) if possible. Does anybody know of a library that can do it? Thanks!

  • What is a great resource for learning about the implementation details of .NET generic collections?

    - by Jimmy W
    Hi all, I'm interested in understanding the underlying implementation details of generic collections in .NET. What I have in mind are details such as how the collections are stored, how each member of a collection is accessed by the CLR, etc. For collections that are analogous to traditional data structures, such as LinkedList and Dictionary, I think I have an understanding of what's going on underneath. However, I'm not as certain about collections like List (how is set up such that it is both indexable and expandable?) and SortedList, so any leads as to what I could look up to learn more about them would be greatly appreciated.

  • How to insert and call by row and column into sqlite3 python, great tutorial problem.

    - by user291071
    Lets say i have a simple array of x rows and y columns with corresponding values, What is the best method to do 3 things? How to insert, update a value at a specific row column? How to select a value for each row and column, import sqlite3 con = sqlite3.connect('simple.db') c = con.cursor() c.execute('''create table simple (links text)''') con.commit() dic = {'x1':{'y1':1.0,'y2':0.0},'x2':{'y1':0.0,'y2':2.0,'y3':1.5},'x3':{'y2':2.0,'y3':1.5}} ucols = {} ## my current thoughts are collect all row values and all column values from dic and populate table row and columns accordingly how to call by row and column i havn't figured out yet ##populate rows in first column for row in dic: print row c.execute("""insert into simple ('links') values ('%s')"""%row) con.commit() ##unique columns for row in dic: print row for col in dic[row]: print col ucols[col]=dic[row][col] ##populate columns for col in ucols: print col c.execute("alter table simple add column '%s' 'float'" % col) con.commit() #functions needed ##insert values into sql by row x and column y?how to do this e.g. x1 and y2 should put in 0.0 ##I tried as follows didn't work for row in dic: for col in dic[row]: val =dic[row][col] c.execute("""update simple SET '%s' = '%f' WHERE 'links'='%s'"""%(col,val,row)) con.commit() ##update value at a specific row x and column y? ## select a value at a specific row x and column y?

  • Wrapping text and div as a unit

    - by mathee
    I have the following that I would like wrapped as units. <div class='tag-box'> <a href=#>Axe Committee</a> <div class='circle'><a href=#>x</a></div> </div> The CSS for these classes are: .tag-box { display:inline; } .circle { display:inline; padding-left:4px; padding-right:4px; background:rgb(196,15,24); /*dark red*/ -moz-border-radius:10px; -webkit-border-radius:10px; } .circle a { font-size:10px; text-decoration:none; color:#fff; position:relative; top:-2px; } I can have upwards of 20 or 30 of these tag-boxes displayed inline. The problem is that the wrapping will break the words from each other or even break the red circle from the link. This makes it hard to differentiate which circle belongs to which link. (In the future, each circle corresponds to a different action with respect to the link.) See below. How do I prevent this kind of wrapping from occurring?

  • AvoidXferMode Tolerance

    - by kayahr
    I have a problem with the following code: protected void onDraw(Canvas canvas) { Paint paint = new Paint(); // Draw a blue circle paint.setColor(Color.BLUE); canvas.drawCircle(100, 100, 50, paint); // Draw a red circle where it collides with the blue one paint.setXfermode(new AvoidXfermode(Color.BLUE, 0, Mode.TARGET)); paint.setColor(Color.RED); canvas.drawCircle(50, 50, 50, paint); } According to the API documentation of AvoidXfermode the tolerance value 0 means that it looks for an EXACT color match. This should work here because I specify the same color as I used for drawing the first circle. But the result is that the red circle is not drawn at all. When I use a tolerance value of 255 instead then it works (red circle is drawn where it collides with the blue one) but that sounds wrong because with such a high tolerance I think it should draw the circle EVERYWHERE. So what's wrong here? API Documentation? Android? Me?

  • Best pathfinding for a 2D world made by CPU Perlin Noise, with random start- and destinationpoints?

    - by Mathias Lykkegaard Lorenzen
    I have a world made by Perlin Noise. It's created on the CPU for consistency between several devices (yes, I know it takes time - I have my techniques that make it fast enough). Now, in my game you play as a fighter-ship-thingy-blob or whatever it's going to be. What matters is that this "thing" that you play as, is placed in the middle of the screen, and moves along with the camera. The white stuff in my world are walls. The black stuff is freely movable. Now, as the player moves around he will constantly see "monsters" spawning around him in a circle (a circle that's larger than the screen though). These monsters move inwards and try to collide with the player. This is the part that's tricky. I want these monsters to constantly spawn, moving towards the player, but avoid walls entirely. I've added a screenshot below that kind of makes it easier to understand (excuse me for my bad drawing - I was using Paint for this). In the image above, the following rules apply. The red dot in the middle is the player itself. The light-green rectangle is the boundaries of the screen (in other words, what the player sees). These boundaries move with the player. The blue circle is the spawning circle. At the circumference of this circle, monsters will spawn constantly. This spawncircle moves with the player and the boundaries of the screen. Each monster spawned (shown as yellow triangles) wants to collide with the player. The pink lines shows the path that I want the monsters to move along (or something similar). What matters is that they reach the player without colliding with the walls. The map itself (the one that is Perlin Noise generated on the CPU) is saved in memory as two-dimensional bit-arrays. A 1 means a wall, and a 0 means an open walkable space. The current tile size is pretty small. I could easily make it a lot larger for increased performance. I've done some path algorithms before such as A*. I don't think that's entirely optimal here though.

  • What is a useful pattern to maintaining an object state in a one to many relationship?

    - by ahenderson
    I am looking for a design for my application, here are the players(classes) involved. struct Transform { // Uses a matrix to transform the position. // Also acts acts as the state of a Dialog. Position transform(Position p); //other methods. }; struct Dialog { // There are multiple dialog for the user to transform the output. Transform& t; void ChangeTranformation(){t.rotate(360);} } struct Algorithm { //gives us a position based on an implementation. For example this can return points on a circle or line. Transform& t; Position m_p; Dialog& d; Position GetCurrentPosition(){ return t.transform(m_p);} //other methods. } Properties I need: Each algorithms has one dialog and each dialog can have many algorithms associated with it. When the user selects an algorithm a dialog associated with that algorithm is displayed. If the user selects a different algorithm then re-selects back the state is restored in the dialog. Basically I want a good design pattern to maintain the state of the dialog given that many algorithms use it and they can be switched back and forth. Does anyone have any suggestions? Here is a use case: Dialog1 has a single edit box to control the radius. Algorithm1 generates points on a unit circle. Algorithm2 is the same as Algorithm1. The user has selected Algorithm1 and entered 2 into the edit box. This will generate points on a circle of radius 2. The user then selects Algorithm2 and enters 10 into the edit box of Dialog1. This will generate points on a circle of radius 10. Finally Algorithm1 is selected again. The edit box of Dialog1 should show 2 and points on a circle of radius 2 should be generated.

  • How to change circular icon to indicate chosen session in unity-greeter?

    - by Chan-Ho Suh
    In Precise (12.04), when I login to lightdm, using the unity-greeter, there's a white circle by my name. For the standard DEs like Unity or XFCE, the circle has a representative icon (Ubuntu symbol or little mouse resp.). I have a session for Awesome window manager which was added when I installed Awesome, but it just shows a blank white circle. I'd like to know how to add an icon to it, or at least some indicator, as unity-greeter doesn't show you what session is set until you click on the circle. I found another question about changing the session names. The answer for it said to change the names in the desktop files in /usr/share/xsessions. Unfortunately, while there is an icon field in those desktop files, they are all blank (Caveat: I no longer have Unity installed, so maybe the Unity one would not be blank. But the Xubuntu desktop file has it blank even though the icon shows in unity-greeter). Update: Here's the png I use as a badge for Awesome. It's not great, but looks reasonably nice: []

  • Control convention for circular movement?

    - by Christian
    I'm currently doing a kind of training project in Unity (still a beginner). It's supposed to be somewhat like Breakout, but instead of just going left and right I want the paddle to circle around the center point. This is all fine and dandy, but the problem I have is: how do you control this with a keyboard or gamepad? For touch and mouse control I could work around the problem by letting the paddle follow the cursor/finger, but with the other control methods I'm a bit stumped. With a keyboard for example, I could either make it so that the Left arrow always moves the paddle clockwise (it starts at the bottom of the circle), or I could link it to the actual direction - meaning that if the paddle is at the bottom, it goes left and up along the circle or, if it's in the upper hemisphere, it moves left and down, both times toward the outer left point of the circle. Both feel kind of weird. With the first one, it can be counter intuitive to press Left to move the paddle right when it's in the upper area, while in the second method you'd need to constantly switch buttons to keep moving. So, long story short: is there any kind of existing standard, convention or accepted example for this type of movement and the corresponding controls? I didn't really know what to google for (control conventions for circular movement was one of the searches I tried, but it didn't give me much), and I also didn't really find anything about this on here. If there is a Question that I simply didn't see, please excuse the duplicate.

  • Spritegroups and colorkeys

    - by Fristi
    I have a problem using spritegroups in pygame. In my situation I have 2 spritegroups, one for humans, one for "infected". A human is represented by a blue circle: image = pygame.Surface((32,32)) image.fill((255,255,255)) pygame.draw.circle(image,(0,0,255),(16,16),16) image = image.convert() image.set_colorkey((255,255,255)) An infected by a red one (same code, different color). I update my spritegroups as follows: self.humans.clear(self.screen, self.bg) self.humans.update(time_passed) self.humans.draw(self.screen) self.infected.clear(self.screen, self.bg) self.infected.update(time_passed) self.infected.draw(self.screen) Self.bg is defined: self.bg = pygame.Surface((SCREEN_WIDTH, SCREEN_HEIGHT)) self.bg.fill((255,255,255)) self.bg.convert() This all works, except that when a red circle overlaps with a blue one, you can see the white corners of the bounding box around the actual circle. Within a spritegroup it works, using the set_colorkey function. This does not happen with overlapping blue circles or overlapping red circles. I tried adding a colorkey to self.bg but that did not work. Same for adding a colorkey to self.screen.

  • Why version of chrome does not matter much more then firefox and firefox does not matter much as IE

    - by anirudha
    Everything not perfect. in software the software make and growth by user feedback like what user expected from the software and want in next version of software. In a chrome Event i hear about the Chromium. you can find some interesting things here Video 1 Video 2 come to the point. when i hear about some good website of india. many of them talking a little thing in common that. We are #1 because we not thing that we make a great application and deploy them and think that we finished own works preharps in a small days we make a small website deploy them and improve them always latter. what the point they all talking about:- the conclusion is that software make by user feedback. they tell that he not spent much time and wait for a long time when their project was finish and they launch their website. preharps they tell that they make a small website in a small time and launched them. make a research on them later and make them better later and website growth as they thing. if they are late then someone else can win even their project was much good them other. not more but a little story:-  before few month i hear about a great website who sold many of books daily i myself purchase some from them to track how they work and how they provided service. i not found any problem with their service. the service they provided is good but when i see their website i found that the mockup code was very badly designed. i am not know the matter how they growth because they used very other stuff who make their website slow. when i research something more i found that their is very hard to implement the website look like them. on their blog they writing about a mail they have. the clone of them make by many other but not goes good as well as they make. after few month later website is looking great. many thing they improved and make them better as  other thing. a another conclusion that same as another story that user feedback. well now come to the point. we talking about Chrome,firefox and IE. what thing is goes common that they all are browser. but something goes different that Chrome is a one of the best browser. from a month many of issue submitted to chrome that user found when they use them. so what is make this different the different is that when feedback goes to someone they take a action and think to make them better so improvement of chrome based on feedback user put using many things. secondly because it's goes open-source many of developer contribute them and make them real browser not real [tape] browser as like IE [a good example]. as you see in video they talking about silent update in chrome and futurecoming chromium. the thing they implement is too good. because by this thing user not worry about a new version. i myself never find a problem that you need to user new version as we found same problem in other application. Well think are great in chrome and now talking about Firefox. Firefox is a best option for development as well as chrome best for surfing the internet. in firefox many thing are great like plugin [ex: Firebug] , addons personas themes and many other thing and customization in firefox make them really a browser not like a joker [IE a good example]. well now come to IE. are IE really great no. someone from Microsoft can say that ha ha hi hi because they can't see the power of open-source. they thing that they make a software and they never need user feedback because they produced windows who really great for user because they used them. example :- before few month Microsoft shipped Windows live. when i use them that i found that their is no sense make for using this one software. suppose you need to write a post through Live writer. the old version are great i myself have no problem but in 2011 i found that they changed everything in user interface. so learn a new thing and spent sometime more to learn a new version whenever need are same and feature are same so why user spent a little time more to learn a lesson who they want to teach even their is no sense to learn them. the problem in 2011 Live not only of mine their are many other have same problem as mine and forget live 2011 after the see a badly design user interface. even they tell we maked in WPF yeah yeah WPF we make in .net. are you can say that what is the matter .net for user. the user have no problem to use WPF based application even you make them fool as we make them in WPF 2020 they are future technologies and we launch it 10 year before only for you yeah you dear customer of mine. yeah they thing WPF is best and thing to implement every software they make even they forget to make better user interface but they also remember to make them next version in WPF. the IE 9 Rc release on 10 febuary. but are they really cool. how much feedback they take and take action of them. their is no answer because they thing to launch a software they never thing what user want and off-course not care of user feedback. as we mention in Firefox and in chrome user feedback have a big matter because sound come from a public and user who use the software not only who make them software as IE 9 have. so feedback take a opportunities to make their software better and less hassel to use them in user hands not only in developer hands. so IE9 is not a good guys who still need of user if they really want a experience. well what Microsoft implemented in IE. i am not talking about that furthure more but i found in article last days[why not say reading a google blog]  yeah see them in http://googleblog.blogspot.com/2011/02/microsofts-bing-uses-google-search.html Well their is nothing good for developer in IE9. the blah blah blah they can always said on MSDN and many other site they have. many from public talking about them because they never can see a good software outside Microsoft. they never talking about Firebug even in books they never show you that. well i know competitor never show you a stuff of competitor i have same issue from Yahoo. on a days i hear from newsletter from them they write a subline on the bottom that USE IE or Firefox to exerience better Web. i am agree with Firefox and i am not know they really talking about IE or joking but i never believe they forget to put chrome. well i know their is corporate rule everyone should follow first. so no problem yahoo i know the matter. well IE:- so what is IE and Why We should use IE. well their is no sense to use IE. the thing we expect from IE but never found that:- first thing is that as a developer we thing the customization as well as other browser have like in chrome have it's own customization and firefox is also great in this matter. but IE really for Web development. are you joking:- the thing they mention in their blog is that IE9 have a new developer tool who have three new panel or tabs. are this joke whenever Firefox and chrome have everyday a new plugin or great upgrade of old plugin they tell we add three new panel first is network second is blah third is blah. well nice joke you make all MSDN blogger i like the way you talking about IE.  even we know what matter the browser have. i thing whenever they make IE 6 they talking about IE as same as they talking today. Secondly their is no other tool to use with IE deveoper tool like Firebug is avilable in IE but not make by IE. firebug team themselves make them for IE. because many of developer thing to use firebug but can't use because they still goes mad about IE because day and night they only hear about tools maked by Microsoft. so no plugin [even very small developer tool] no customized no personas on themse. no update yeah why forget these topic come with us and share a little thing more. IE launch IE 6 after 7 after 8 and now 9 [even in future] but what they do. they do nothing on user feedback they still thing WPF is great because colors make user cool and they forget to implement other things as other already provide. Chrome and Firefox are come after IE. Mozilla firefox come in 2004 and chrome is late in 2008. even they are late they still focus on Developer and thing they feel first is that customization like developer tool , themese and perfsonas and many other great things. are they can find in IE even next i means 10 yeah IE10 never because they thing only making a software or force user to use new version of OS. i am confused that why not wait and force user to purchase windows 8 instead of 7. so IE have no customization even small developer tool i thing that they make a customizable interface like in firefox who configure by about:config. so thing is discussed about really not a point we thing to goes but now it's clear what is making no matter for version in Firefox and chrome. because chrome and firefox not wait for  a long time and explode a bomb to make publicity. they still work and make upgrade possible to user as soon as possible. [chrome never tell about they goes old they himself update them].so update comes soon in Firefox and in chrome but in IE their is a long time to wait and they make them without feedback. so IE really not for human and not really for us. whenver you found a bug in chrome and in firefox you report them and found that they are work in progressed and can be see in next version of firefox. but what you see whenever you see IE. you found that what the bug can found in IE whenver they not implemented same feature in IE. well IE 9 is next IE6 for developer. conclusion:-  after reading a whole post you find that i hate all thing about IE. why are i write a big post on a small pity software IE. why i open the poll of IE. are their anything in IE break my heart. are their is something goes wrong with me and with my IE9. are their is anything i got with IE9. why i write a big post. well as a developer play a trick that give sometime to chrome to make them better and some other to make firefox better and feel something you contribute really have a matter as a contribute you find some other and their thought on same software. some are great maybe some of them blah blah. but are their is true that outside Microsoft their is no good sollution can make because it's outside Microsoft. their is not true. the thing developer make not have matter even using Microsoft technologies or outside technologies of MS. so stop this i not want to talking some other things just stop it. i means their is no more blah i want to talking with you for IE.i still hate them and believe it is next IE6 for Web. Answers: if you still need a answer in lines that the answer is that IE late update as long as they can and also make force user to upgrade IE9 because they want to promote windows first then thing about IE and chrome and firefox not do that as same as IE. so IE is late and user forced software. in firefox and chrome upgrade come soon as soon as they possible. Thanks to give me a great time and red my blah on Blah i means IE9 Thanks again Anirudha

    I'm working on a 2D game in which I would like to do collision detection between a moving circle and some kind of static curves (maybe Bezier curves). Currently my game features only straight lines as the static geometry and I'm doing the collision detection by calculating the distance from the circle to the lines, and projecting the circle out of the line in case the distance is less than the circles radius. How can I do this kind of collision detection in a relative straightforward way? I know for instance that Box2D features collision detection with Bezier curves. I don't need a full featured collision detection mechanism, just something that can do what I've described.
