• apportcheckresume recurring error and gnome shell fixations

  - by feedyourhead

  Since installing Ubuntu 12.10 Gnome remix I encounter systemm's unpredictable and unwanted behavior. Almost after each resume from suspend (or even after unlocking the screen after it goes blank) I get apportcheckresume error and message "Ubuntu 12.10 has encountered an internal error".Many times the system event wont resume and I need to restart it. Other times log in screen is not visible, the screen is blank and i have to write my password "in blanco". Sometimes additional thing also happens - textures get messed up and background and windows get distorted by horizontal lines Sorry I can't localize the log file for the errors. My system specification: Ubuntu 12.10 3.5.0-19-generic Gnome 3.6 Thinkpad T400 Graphics Mobile Intel® GM45 Express Chipset Intel® Core™2 Duo CPU P8600

• Graffiti is a Sinatra-inspired Groovy Framework

  - by kerry

  Playing around with Sinatra the other day and realized I could really use something like this for Groovy. Thus, Graffiti was born. It’s basically a thin wrapper around Jetty. At first, I thought I might write my own server for it (everybody needs to do that once, don’t they?), but decided to invoke the ’simplest thing that could possibly work’ principle. Here is the requisite ‘Hello World’ example: import graffiti.* @Grab('com.goodercode:graffiti:1.0-SNAPSHOT') @Get('/helloworld') def hello() { 'Hello World' } Graffiti.serve this The code, plus more documentation is hosted under my github account.

• Compute if a function is pure

  - by Oni

  As per Wikipedia: In computer programming, a function may be described as pure if both these statements about the function hold: The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change as program execution proceeds or between different executions of the program, nor can it depend on any external input from I/O devices. Evaluation of the result does not cause any semantically observable side effect or output, such as mutation of mutable objects or output to I/O devices. I am wondering if it is possible to write a function that compute if a function is pure or not. Example code in Javascript: function sum(a,b) { return a+b; } function say(x){ console.log(x); } isPure(sum) // True isPure(say) // False

• How to deal with ad-hoc mindsets?

  - by Rotian

  I joined a dev team of six two month ago. People are nice, all is good. But more and more I observe an ad-hoc mindset. Stuff gets quick fixed, at the cost of future usability, there is little testing and two people happily admitted, that they like to carry the knowledge around in their head, rather than to write it down. How to deal with this? I'd like to lead by example, but time is limited - I like architecting and actually implementing the stuff. But I'm afraid the ad-hoc mindset infects me and rather than striving for clearness and simplicity in design and code - which isn't simple to establish - I get pulled down the drain of an endless spiral of hacks on hacks - which no outsider can uncouple - just for schedule's and management's sake.

• Does heavy library and snippet codes usage make you a bad programmer?

  - by Henrik P.

  Overall I'm in programming for about 8 years now and it seems to me that I'm relying more and more on open source libraries and snippets (damn you GitHub!) to "get the job done". I know that in time I could write me own implementation but I like to focus on the overall design. Is this normal (non cooperate environment)? Does it make you a bad programmer if "programming" is nothing more than cluing different libraries together. Feels like it. I know about "don't reinvent the wheel" but what happens when you don't invent a single wheel anymore. What's your take on this?

• Python C API return more than one value / object without building a tuple [migrated]

  - by Grisu

  I got the following problem. I have written a C-Extension to Python(2.7 / 3.2) to interface a self written software library. Unfortunately I need to return two values from the function where the last one is optional. In Python I tried def func(x,y): return x+y, x-y test = func(13,4) but test is a tuple. If I write test1,test2 = func(13,4) I got both values separated. Is there a possibility to return only one value without unpacking the tuple, i.e. the second(,.. third, ..fourth) value gets neglected? And if such a solution existst, how does it look for the C-API? Because return Py_BuildValue("ii",x+y,x-y); results in a tuple as well.

• Is there a language between C and C++?

  - by Robert Martin

  I really like the simple and transparent nature of C: when I write C code I feel unencumbered by "leaky abstractions" and can almost always make a shrewd guess as to the assembly I'm producing. I also like the simple, familiar syntax for C. However, C doesn't have these simple, helpful doodads that C++ offers like classes, simplified non-cstring handling, etc. I know that it's all possible to implement in C using jump tables and the like, but that's a bit wordy at times, and not very type-safe for various reasons. I'm not a fan of the over-emphasis on objects in C++, though, and I'm gun shy of the 'new' operator and the like. C++ seems to have just a few too many hiccups to, for instance, be used as a system programming language. Does there exist a language that sits between C and C++ on the scale of widgets and doodads? Disclaimer: I mean this as purely a factual question. I do not intend to anger you because I don't share your view that C{,++} is good enough to do whatever I'm planning.

• Clean file separators in Ruby without File.join

  - by kerry

  I love anything that can be done to clean up source code and make it more readable.  So, when I came upon this post, I was pretty excited.  This is precisely the kind of thing I love. I have never felt good about ‘file separator’ strings b/c of their ugliness and verbosity. In Java we have: 1: String path = "lib"+File.separator+"etc"; And in Ruby a popular method is: 1: path = File.join("lib","etc") Now, by overloading the ‘/’ operator on a String in Ruby: 1: class String 2: def /(str_to_join) 3: File.join(self, str_to_join) 4: end 5: end We can now write: 1: path = 'lib'/'src'/'main' Brilliant!

• Dynamic Tab Implementation in ADF

  - by Vijay Mohan

  Well, this can be a common usecase across apps to open tabs dynamically at runtime based on the request.Well, in order to achieve this you can have a parent container, lets say a panelTab component.Inside panelTab , u can have a showDetailItem inside an af:foreach or an af:iterator binded to a bean static list which will have as many show detail items as you wish to be shown.something like this.private static List = { new showDetailItem("1"),new ShowDetailItem("2") ...};now in the backing bean you can have a method that takes care of rendering and disclosing an specific tab based on the index.public void openMyTab(){List<MyItems> list = refToParentContainer.getChildren();int indexOfTabToBeOpened = //Write a method that will compute the tab index of the next //tab.list.get(index).setRendered(true);list.get(index).setDisclosed(true);similarly you can set other properties too.}Else, instead of having af:foreach/iterator iterating through the SD items , you can go for static SDs in the page with render property set to false and then you can follow the same approach to render/disclose it at runtime.

• Black & White screen after resuming from Suspend [Ubuntu 12.04]

  - by Rakatash

  I recently thought of giving Linux a try with Ubuntu 12.04. So far I managed to figure out how to troubleshoot and fix some of my older issues. But i wasnt able to find a problem similar to mine. The issue is, whenever my laptop starts up after suspend, the screen stays black for a short while. then after that comes a black and white 8-bit kinda screen with nothing else. I am not sure if it's an issue with the graphic card or not. because I am able to write my login password and proceed normally if i wait till this screen shows up...after that everything is displayed normally. is there a fix for this?

• What do I need to get a job with a major game company?

  - by MahanGM

  I've been recently working with DirectX and getting familiar with game engines, sub-systems and have done game development for the last 5 years. I have a real question for those whom have worked in larger game making companies before. How is it possible to get to into these big game creators such as Ubisoft, Infinity Ward or EA. I'm not a beginner in my field and I'm going to produce a real nice 2D platform with my team this year, which is the result of 5 years 2D game creation experience. I'm working with prepared engines such as Unity3D or Game Maker software and using .Net with C# to write many tools for our production and proceeding in my way but never had a real engine programming experience 'till now. I'm now reading good books around this topic but I wanted to know: Is it possible to become an employee in big game company by just reading books? I mean beside having an active mind and new ideas and being a solution solver.

• Random map generation

  - by Thomas Owers

  I'm starting/started a 2D tilemap RPG game in Java and I want to implement random map generation. I have a list of different tiles, (dirt/sand/stone/grass/gravel etc) along with water tiles and path tiles, the problem I have is that I have no idea where to start on generating a map randomly. It would need to have terrain sections (Like a part of it will be sand, part dirt, etc.) Similar to how Minecraft is where you have different biomes and they seamlessly transform into each other. Lastly I would also need to add random paths into this as well going in different directions all over the map. I'm not asking anyone to write me all the code or anything, just piont me into the right direction please. tl;dr - Generate a tile map with biomes, paths and make sure the biomes seamlessly go into each other.

• Convince developer to use IDE

  - by artjom

  There is a developer, lets call him John (currently on probationary period) in company(pretty small company approx. 10 persons, 3 developers, one of them works long in this company know business process around and can be consider as Team leader) who didn't want to use any IDE at all(he is using some text editor). Application this team working on is medium size Java application with Spring Hibernate technology stack and refactoring/adding new features to launch new version of that application in near future. John performance working without IDE on this application is lower then desirable, team leader's (lets call him Bill) assumption is this happens because John is not using IDE. Bill try to persuade John to use IDE, but this idea meets a lot of resistance and main reason is "I want to be in total control of what I am doing, so I need to write all code by myself". How can Bill convince John to try to use IDE? (considering the fact what Bill already protected John from company owner several complaints about John performance)

• How do I let customers run arbitrary code as securely as possible?

  - by Tyler

  I'd like to offer a service where customers can write arbitrary java code, send it to me, and I'll run it for them on Amazon EC2. My question is: how can I do this without exposing one customer's data to another customer? Right now I'm thinking that each customer can be sandboxed as their own OS-level user with restricted permissions. Is that good enough? I understand that this is a tricky issue, but it seems to be one that many people, such as the designers of multi-user OS's and Amazon themselves are solving, so I am optimistic that there might be a good approach.

• Where I can find SQL Generated by Entity framework?

  - by Jalpesh P. Vadgama

  Few days back I was optimizing the performance with Entity framework and Linq queries and I was using LinqPad and looking SQL generated by the Linq or entity framework queries. After some point of time I got the same question in mind that how I can find the SQL Statement generated by Entity framework?. After some struggling I have managed to found the way of finding SQL Statement so I thought it would be a great idea to write a post about  same and share my knowledge about that. So in this post I will explain how to find SQL statements generated Entity framework queries. Read More on dotnetjalps.com

• C# Interview Preparation - References?

  - by Kanini

  This is a specific question relating to C#. However, it can be extrapolated to other languages too. While one is preparing for an interview of a C# Developer (ASP.NET or WinForms or ), what would be the typical reference material that one should look at? Are there any good books/interview question collections that one should look at so that they can be better prepared? This is just to know the different scenarios. For example, I might be writing SQL Stored Procedures and Queries, but I might stumble when asked suddenly Given an Employee Table with the following column(s). EmployeeId, EmployeeName, ManagerId Write a SQL Query which will get me the Name of Employee and Manager Name? NOTE: I am not asking for a Question Bank so that I can learn by rote what the questions are and reproduce them (which, obviously will NOT work!)

• Should I update blog posts or rewrite them as technology (and me) changes?

  - by Rachel

  I started a programming blog earlier this year, and since I started it some things have changed. Some changes are due to technology changing, some changes are due to my code libraries improving, and some (ok, probably most) are due to me changing as I learn more. I want to go back and completely re-write certain blog posts. Is it better to rewrite posts to remove old information and update them with new stuff, or to create entirely new posts and possibly take down old ones? I'm not talking about small changes to the code, or an extra few sentences, but complete rewrites with new code, new information, etc. Some things to consider are comments on the post, subscribers who receive updates when new posts are created, and user bookmarks.

• A good interpreted language for a small embedded project

  - by Earlz

  I have an mbed which has a small ARM Cortex M3 on it. Basically, my effective resources for the project are ~25Kb of RAM and ~400Kb of Flash. For I/O I'll have a PS/2 keyboard, a VGA framebuffer(with character output), and an SD card for saving/loading programs(up to a couple of Mb maybe) The reason I ask this here is because I'm trying to figure out what programming language to implement on the thing. I'm looking for an interpreted language that's easy for me to implement, and won't break the bank on my resources. I also intend for this to be at least possible to write on th device itself, though the editor can be interpreted(yay bootstrapping) Anyway, I've looked at a few simple languages. Some nice candidates: Forth BASIC Scheme? Has anyone done something like this or know of any languages that can fit this bill or have comments about my three candidates so far?

• Book review: SQL Server Transaction Log Management

  - by Hugo Kornelis

  It was an offer I could not resist. I was promised a free copy of one of the newest books from Red Gate Books , SQL Server Transaction Log Management (by Tony Davis and Gail Shaw ), with the caveat that I should write a review after reading it. Mind you, not a commercial, “make sure we sell more copies” kind of review, but a review of my actual thoughts. Yes, I got explicit permission to be my usual brutally honest self. A total win/win for me! First, I get a free book – and free is always good,...(read more)

• Why are most GNU's software written in C

  - by BallroomProgrammer

  I am a Java developer, and I rarely write GUI program in C. However, I noticed that many GNU's projects, such as PSPP, R, Dia, etc., are written in C, instead of Java or C++. I personally don't mind this, but I am really curious why GNU favors C so much. My understanding is that C is the one that supports the least in object-oriented programming, and today's CS education really emphasizes OOP, as OOP really makes codes more reusable. In this case, why would so many developers choose to develop in C instead of C++ or Java. Does anyone know why GNU's software are so exclusively written in C? Do you think or GNU's software should be written in C++ or Java so that the source code could be more useful to people? Why or why not?

• Checking for cross-site scripting vulnerabilities in Perl web applications

  - by David Scholefield

  I'm putting together some notes for a dev team on how to write secure Perl code - especially taking into account the current OWASP top 10 web application vulnerabilities. For cross-site scripting I've included information on ensuring that all output to the browser is checked and escaped where necessary, but I'm looking for more automated mechanisms that would mean a developer doesn't have to think about every output statement and, potentially, miss one. Perl's 'taint' function sounds like it should be a help because it distrusts all user input, but it doesn't complain on tainted data being output to the browser. Apart from checking all output statements individually (probably by calling a generic sanitizing function) does anyone have any ideas on how Perl can help with this with existing libraries or techniques?

• What is 'work' in the Pomodoro Technique?

  - by Sachin Kainth

  I have just started to use Pomodoro today and I am trying to work out what I should and should not do during my 25 minute work time. For my 25 minute work stint I started to write some code and realised that I had done something similar in a related project so I opened that solution to copy and paste that existing code. Question is, is this allowed? Also, if during my 25 minutes I realise that there is an important work-related email that I need to send can I do that or should that wait for the next 25 minutes or the break. I am writing this question during my, now extended, 5 minute break. Is this work or is it a break? I really would appreciate some guidance as I really want to use Pomodoro to focus better on my work. Another thing that happened to me was that a Adobe AIR update alert came up on my desktop during the 25 minutes. Should I ignore such things until the break? Sachin

• What is Atomicity?

  - by James Jeffery

  I'm really struggling to find a concrete, easy to grasp, explanation of Atomicity. My understanding thus far is that to ensure an operation is atomic you wrap the critical code in a locker. But that's about as much as I actually understand. Definitions such as the one below make no sense to me at all. An operation during which a processor can simultaneously read a location and write it in the same bus operation. This prevents any other processor or I/O device from writing or reading memory until the operation is complete. Atomic implies indivisibility and irreducibility, so an atomic operation must be performed entirely or not performed at all. What does the last sentence mean? Is the term indivisibility relating to mathematics or something else? Sometimes the jargon with these topics confuse more than they teach.

• How to get quality sprite sheet generation with rotations

  - by BenMaddox

  I'm working on a game that uses sprite sheets with rotation for animations. While the effect is pretty good, the quality of the rotations is somewhat lacking. I exported a flash animation to png sequence and then used a C# app to do matrix based rotations (System.Drawing.Drawing2D.Matrix). Unfortunately, there are several places where the image gets clipped. What would you suggest for a way to get high quality rotations from either flash or the exported PNGs? A circle should fit within the same image boundaries. I don't mind a new program that I must write or an existing program I must download/buy.
