• How to prevent script not to stop after apt-get?

  - by Eonil

  I keep some bash snippets and copy&paste them when I needed for management. But I discovered apt-get cancels script execution. Here's my script where problematic. apt-get -y install gcc g++ make cmake perl cd ~/ mkdir t1 cd t1 I copy & paste this script on OS X Terminal to Ubuntu 12.04 LTS server (fresh install on VM) Script always stop after apt-get finished. I run this command with root account like this. ssh user1@server <password…> sudo su <password…> apt-get -y install gcc g++ make cmake perl cd ~/ mkdir t1 cd t1 Can this be a problem? Or why my script stops after apt-get finished, and how to make it to continue?

• Unity gizmos vs. referenced game objects

  - by DuckMaestro

  I'm designing a Unity script that I intend to be highly reusable and as easy as possible to setup within the editor. To this end, a number of properties of this script really need some kind of visual representation on screen. It is an unresolved question to me whether the design of the script should require references to placeholder game objects, OR just Vector3's and float's that have associated gizmos drawn for them. Normally a gizmo would be a natural choice, except that Unity gizmos are not directly manipulable (as far as I can tell). Because of this shortcoming I'm having to consider whether depending on references to placeholder game objects is a more designer-friendly approach ultimately, in spite of the extra setup required, and that it might be counter-intuitive when the placeholder game objects disappear at run-time (which my script would do). Is there a community standard or preference here in this case? Can a Unity-experienced game programmer / designer speak to which approach they feel is more intuitive or more convenient to setup, when using a 3rd party script? Or is this just splitting hairs as long as I ship an example prefab with my script?

• Language Design: Are languages like Python and CoffeeScript really more comprehensible?

  - by kittensatplay

  The "Verbally Readable !== Quicker Comprehension" argument on http://ryanflorence.com/2011/case-against-coffeescript/ is really potent and interesting. I and I'm sure others would be very interested in evidence arguing against this. There's clear evidence for this and I believe it. People naturally think in images, not words, so we should be designing languages that aren't similar to human language like English, French, whatever. Being "readable" is quicker comprehension. Most articles on Wikipedia are not readable as they are long, boring, dry, sluggish and very very wordy. Because Wikipedia documents a ton of info, it is not especially helpful when compared to sites with more practical, useful and relevant info. Languages like Python and CoffeScript are "verbally readable" in that they are closer to English syntax. Having programmed firstly and mainly in Python, I'm not so sure this is really a good thing. The second interesting argument is that CoffeeScript is an intermediator, a step between two ends, which may increase the chance of bugs. While CoffeeScript has other practical benefits, this question specifically requests evidence showing support for the counter-case of language "readability"

• How to revert to Eclipse's old behavior when double-clicking on frames or windows, in Juno?

  - by mattquiros

  I find Eclipse Juno very counter-intuitive. In my workspace, I used to just have the package view at the left, my code on the right, and whenever I'm printing something in the console, that's only when the console frame shows up from the bottom right. When you double click on a particular window, it either only goes fullscreen within Eclipse, or back to its original size together with the size of the other frames. In Juno, however, it seems that frames are put on layers on top of each other. When I print something to the console, the output frame only shows up as a small, useless square to my right. When I double-click, it goes full screen. When I double-click again, it occupies the full right frame, hiding my code. I double-click again and it goes full screen, then it double-clicks before it shares the right frame with my code on top of it. Then when I minimize it, it goes to the side. Any way to go back to the good old days of Eclipse? Thanks.

• How to manage Agile developers working with traditional (serial) business persons?

  - by Riggy

  Good afternoon, My work environment has some problems. Our IT team is trying to be more agile, but we're not really getting buy-in from the business. They attend our daily stand-ups and sprint reviews, and they help with sprint planning, but then they turn around and do 4 months of requirements gathering for a project before moving forward with a (mostly) serial development style. The sprint goals are things like "get XX% closer to release". For the IT team, they've turned the Sprints into a sort of death march. We end a Sprint one day and start a new Sprint the very next day. There's no reflection or changes done between sprints, only during. Having never done any of the agile methodologies before, I haven't had a very pleasant introduction to them. So my questions are: 1) Should there be some time (perhaps a week or so) between sprints to do the reflection/introspection/changes/etc.? Or are back-to-back-to-back sprints the norm? 2) Is there any chance for survival for an agile team with no agile business counter-parts? If not, are there some transitional methodologies or even tips for moving the business towards an iterative if not necessarily agile mindset? 3) Should your entire team be on every sprint? We have almost 20 programmers on a single sprint but working on completely different projects (typically teams of 3-5, sometimes larger). Is it normal to have a single sprint or should we be trying to manage multiple independent sprints? Should we be trying to keep the multiple sprints in concurrent lockstep or should their timetables be allowed to overlap and be flexible? Any thoughts or advice is appreciated. This is my first time coming over from SO for a question, so please let me know if there are better ways to phrase these kinds of questions (faq was rather helpful, but still not sure I'm following it perfectly). Thanks!

• Why is quicksort better than other sorting algorithms in practice?

  - by Raphael

  This is a repost of a question on cs.SE by Janoma. Full credits and spoils to him or cs.SE. In a standard algorithms course we are taught that quicksort is O(n log n) on average and O(n²) in the worst case. At the same time, other sorting algorithms are studied which are O(n log n) in the worst case (like mergesort and heapsort), and even linear time in the best case (like bubblesort) but with some additional needs of memory. After a quick glance at some more running times it is natural to say that quicksort should not be as efficient as others. Also, consider that students learn in basic programming courses that recursion is not really good in general because it could use too much memory, etc. Therefore (and even though this is not a real argument), this gives the idea that quicksort might not be really good because it is a recursive algorithm. Why, then, does quicksort outperform other sorting algorithms in practice? Does it have to do with the structure of real-world data? Does it have to do with the way memory works in computers? I know that some memories are way faster than others, but I don't know if that's the real reason for this counter-intuitive performance (when compared to theoretical estimates).

• How to write loosely coupled classes in node.js

  - by lortabac

  I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

• What is the standard technique for shifting the frames of a sprite according to user input?

  - by virtual__

  From my own experience, I developed two techniques for changing the sprites of a character that's reacting to user input -- this in the context of a classic 2D platformer. The first one is to store all character's pixmaps in a list, putting the index of the currently used pixmap in an ordinary variable. This way, every time the player presses a key -- say the right arrow for moving the character forward -- the graphics engine sees what's the next pixmap to draw, draws it, and increments the index counter. That's a pretty common approach I believe, the problem is that in this case the animation's quality depends not only on the number of sprites available but also on how often your engine listens to user input. The second technique is to actually play an animation every key press event. For this you can use any sort of animation framework you want. It's only necessary to set the timer, the animation steps and to call the animation's play() method on your key press event handler. The problem with that approach is that is lacks responsiveness, since the character won't react to any input while the current animation is still being played. What I want to know is whether you are using one of these techniques -- or something similar -- in your games, or whether there's a standard method for animating sprites out there that's widely known by everybody but me.

• When profiling a function for time use, what information is desirable?

  - by AaronMcSmooth

  I'm writing a program similar to Python's timeit module. The idea is to time a function by executing it anywhere from 10 to 100,000 times depending on how long it takes and then report results. I've read that the most important number is the minimum execution time because this is the number that best reflects how fast the machine can run the code in question in the absence of other programs competing for processor time and memory. This argument makes sense to me. Would you be happy with this? Would you want to know the average time or the standard deviation? Is there some other measure that you consider more important?

• JavaScript malware analysis

  - by begueradj

  I want to test websites for JavaScript malware presence . I plan to develop a Python program that sends the URL of a given website to a virtual machine where the dynamic execution of the eventual malicious JavaScript embedded in the website's page is monitored. My questions: Should my VM be Windows or Linux ? What if the malware damages my VM: is there a hint how to avoid that ? Or launch a new VM automatically instead ? If I use telnet client library to communicate with the VM: must I implement a server within the VM to deal with my queries or can I overcome this ? I am jut looing for hints, general ideas. Thank you for any help.

• Communication between Box2D and libGDX Stage (Scene2D) running in separate threads

  - by atok

  I'm making a physics based 2D game using libGDX and Box2D. I want to move the execution of the simulation out of render thread. I use immutable messages and the BlockingQueue to pass the information about player actions. The Box2D applies forces and runs a frame of simulation. In the next step I would like to sync back the changes and update Scene2D Actors accordingly. Making an immutable copy of the state of the game world and sending it back using Gdx.app.postRunnable() is one option but it seems inefficient. Is there any other option?

• How do you tell if advice from a senior developer is bad?

  - by learnjourney

  Recently, I started my first job as a junior developer and I have a more senior developer in charge of mentoring me in this small company. However, there are several times when he would give me advice on things that I just couldn't agree with (it goes against what I learned in several good books on the topic written by the experts, questions I asked on some Q&A sites also agree with me) and given our busy schedule, we probably have no time for long debates. So far, I have been trying to avoid the issue by listening to him, raising a counterpoint based on what I've learned as current good practices. He raises his original point again (most of the time he will say best practice, more maintainable but just didn't go further), I take a note (since he didn't raise a new point to counter my counterpoint), think about it and research at home, but don't make any changes (I'm still not convinced). But recently, he approached me yet again, saw my code and asked me why haven't I changed it to his suggestion. This is the 3rd time in 2--3 weeks. As a junior developer, I know that I should respect him, but at the same time I just can't agree with some of his advice. Yet I'm being pressured to make changes that I think will make the project worse. Of course as an inexperienced developer, I could be wrong and his way might be better, it may be 1 of those exception cases. My question is: what can I do to better judge if a senior developer's advice is good, bad or maybe it's (good but outdated in today context)? And if it is bad/outdated, what tactics can I use to not implement it his way despite his 'pressures' while maintaining the fact that I respect him as a senior?

• Where do the responsibilities of build tools end and those of CI tools start?

  - by BrandonV

  In the delivery of software, and within the sense of the deployment pipeline, where do the responsibilities of build tools, like Maven, end, and the responsibilities of CI start? As a rough example of a problem that arises; should build tools have any responsibility to the configuration and execution of acceptance tests when they are further down the pipeline than actually building the artifact? I'd like an answer that addresses in the sense of deployment lifecycle phases rather than in specifics, like my example. Although examples would help bolster the answer.

• Application that provides unique keys to multiple threads

  - by poly

  Thanks all for your help before. So, this is what I came up with so far, the requirements are, application has two or more threads and each thread requires a unique session/transaction ID. is the below considered thread safe? thread 1 will register itself with get_id by sending it's pid thread 2 will do the same then thread 1 & 2 will call the function to get a unique ID function get_id(bool choice/*register thread or get id*/, pid_t pid) { static int pid[15][1]={0};//not sure if this work, anyway considor any it's been set to 0 by any other way than this static int total_threads = 0; static int i = 0; int x=0,y=0; if (choice) // thread registeration part { for(x=0;x<15;x++) { if (pid[x][0]==0); { pid[x][0] = (int) pid; pid[x][1] = (x & pidx[x][1]) << 24;//initiate counter for this PID by shifting x to the 25th bit, it could be any other bit, it's just to set a range. //so the range will be between 0x0000000 and 0x0ffffff, the second one will be 0x1000000 and 0x1ffffff, break; } total_threads++; } } //search if pid exist or not, if yes return transaction id for(x=0;x<15;x++) { if (pid[x][0]==pid); { pid[x][1]++;//put some test here to reset the number to 0 if it reaches 0x0ffffff return pid[x][1]; break; } } }

• Placing advice on any parameter of a given type in AspectJ

  Hi, Im doing a POC using Aspectj. class BaseInfo{..} class UserInfo extends BaseInfo{..} class UserService { public void getUser(UserInfo userInfo){..} public void deleteUser(String userId){..} } I've defined an advice, that gets invoked when I pass an UserInfo instance.But when i try to pass the BaseInfo, the advice is not getting invoked. Below block executes the afterMethod as expected for getUser. &ltaop:pointcut id="aopafterMethod" expression="execution(* UserService.*(..,UserInfo,..))" / &gtaop:after pointcut-ref="aopafterMethod" method="afterMethod" / But when i try to give BaseInfo instead of UserInfo, the aspect is not getting triggered. Am i missing something? Kindly help me on this issue.

• New "How do I ..." series

  - by Maria Colgan

  Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

• What online games would let me practice AI development?

  - by Myn

  I am working on a project experimenting with Artificial Intelligence design methodologies for online world avatars. Online world here is quite open to interpretation; Second Life is just as applicable as Counter Strike, for example. To carry out these experiments, I must first develop an intelligent agent for the world in question. However, I am honestly quite stuck as to which game I could use for this. My preference was to develop an intelligent "bot" to play an MMORPG, but the legal restrictions of such games prevent me. Likewise with most FPS games the use of an intelligent agent in place of a human player is considered cheating. The alternative, of course, is to create an NPC bot; an intelligent agent that populates the world alongside the player(s) rather than replacing a particular player. However, I'm struggling to find a game that would enable me to create an intelligent opponent either. I suppose the main requirements would be a game allows a third party program to use the function calls usually utilised by players and read feedback on the state of the world. Quake III and Unreal Tournament have been suggested before, but they have already been the subject of work on this research project. Short of writing my own online game from scratch, what games would allow me, through middleware, an API, or otherwise, to create either an artificially intelligent player or a bot?

• Dynamic Components

  - by Alex

  I am attempting to design a component-based architecture that allows Components to be dynamically enabled and disabled, much like the system employed by Unity3D. For example, all Components are implicitly enabled by default; however, if one desires to halt execution of code for a particular Component, one can disable it. Naively, I want to have a boolean flag in Component (which is an abstract class), and somehow serialize all method calls into strings, so that some sort of ComponentManager can check if a given Component is enabled/disabled before processing a method call on it. However, this is a pretty bad solution. I feel like I should employ some variation of the state paradigm, but I have yet to make progress. Any help would be greatly appreciated,

• Recommended display/background brightness ratio and UI color schemes [duplicate]

  - by user1306322

  This question already has an answer here: Colour scheme for editor - guidelines or medical reccomendations 3 answers I'm a professional programmer, which means I spend a lot of time staring at various displays. Recently I've been having some problems with my eyes, so I went to talk to several doctors, which all gave me different recommendations as to how bright the background of the room should be in comparison to the display's brightness. It was very confusing, as some of them even agreed with counter-arguments of others, which made it all even less clear. So I'd like to ask the professional programmers, as people who actually have some experience with that. Some of the doctors said that looking at a monitor is like looking at a book, so the brightness ratios should be approximately the same. Others said that background should be as bright as the display itself, because then there is no brightness difference at the edges, and that's what may cause eye fatigue. From my own experience, I can say that reading a book isn't the same as writing or debugging a program, where you have to pay close attention to each symbol, and in books most words are easily recognizable without focusing too hard on them. Also, books are black on white and I myself use the default (dark text, white bg) color scheme for my IDE, but I've seen some programmers use mid-bright text on very dark background color schemes. So I'd like to ask what are the recommended display/background brightness ratios for programming? I'm not sure this site is the right one for this kind of questions, so if you know a better one, please comment.
