  • How do I combine all lines in a text file into a single line?

    - by John
    I want to get all lines in a text into one line. I'm a beginner at coding trying to learn by doing. I've spent four hours trying to solve this problem. I know there's a simple solution to this problem. Here's what I've been trying. sed -e 'N;s/\n//' myfile.txt #Does nothing sed -e :a -e N -e 's/\n/ /' -e ta myfile.txt #output all messed up and I can't make head nor tail of the syntax cat myfile.txt | tr -d '\n' myfile.txt # Deletes all lines Here's the text file: 500212 262578-4-4 23200 GRIFFITH LABORATORIES LTD GRIFFITH LABORATORIES SOUTH DUBLIN COUNTY COUNCIL OFFICE OFFICE (INDUSTRIAL) List Rateable 2 Pineview Industrial Estate Firhouse Road Knocklyon 31 Dec 2007 01 Jan 2008" I can't figure out where I've gone wrong....

  • downgrade ppa packages to versions available at a previous point in time

    - by Will
    The backstory is that the normal Intel GPU drivers don't do the various OpenGL extensions that my hobby coding and some games want. So I have to install xorg-edgers and then its happy. However, last Wednesday or so there was an update to xorg-edgers - lots of packages - and it broke badly; the drivers lock up and take the whole computer with them; hard reset required. So how can you downgrade - select package versions in a PPA that represent a point in the past, ignoring versions newer than that?

  • Question about a simple design problem

    - by Uri
    At work I stumbled uppon a method. It made a query, and returned a String based on the result of the query, such as de ID of a customer. If the query didn't return a single customer, it'd return a null. Otherwise, it'd return a String with the ID's of them. It looked like this: String error = getOwners(); if (error != null) { throw new Exception("Can't delete, the flat is owned by: " + error); } ... Ignoring the fact that getCustomers() returns a null when it should instead return an empty String, two things are happening here. It checks if the flat is owned by someone, and then returns them. I think a more readable logic would be to do this: if (isOwned) { throw new Exception("Can't delete, the flat is owned by: " + getOwners()); } ... The problem is that the first way does with one query what I do with two queries to the database. What would be a good solution involving good design and efficiency for this?

  • What''s easy extensible technique to store game data?

    - by Miro
    I'm looking for library/technique for storing my game resources - levels, object (effects,world info), items(price,effects,...), NPC(visual info, behavior), everything except graphics/audio stuff. I've seen lua used for Awesome WM configuration. protobuf looks good, but it seems to be designed for network communication. I've tried to write my own parser, but as the project grows it's more and more harder to manage it and catch all the bugs. My requiremets: stability easy extension of data without need to convert older versions to newer good(don't have to be the best) performance of loading not much coding not XML!

  • What should you include in a development approach document?

    - by Liggy
    I'm in the middle of co-producing a "development approach" document for off-shore resources as they ramp up onto our project. The most recent (similar) document our company has used is over 80 pages, and that does not include coding standards/conventions documents. My concern is that this document will not be consumable and will therefore fail. What should be in a development approach document? Are there any decent guidelines on this topic? EDIT: The development approach document should detail the practices and techniques that will be used by software developers while software is designed, built, and tested.

  • "Guiding" a Domain Expert to Retire from Programming

    - by James Kolpack
    I've got a friend who does IT at a local non-profit where they're using a custom web application which is no longer supported by the company who built it. (out of business, support was too expensive, I'm not sure...) Development on this app started around 10+ years ago so the technologies being harnessed are pretty out of date now - classic asp using vbscript and SQL Server 2000. The application domain is in the realm of government bookkeeping - so even though the development team is long gone, there are often new requirements of this software. Enter the... The domain expert. This is an middle aged accounting whiz without much (or any?) prior development experience. He studied the pages, code and queries and learned how to ape the style of the original team which, believe me, is mediocre at best. He's very clever and very tenacious but has no experience in software beyond what he's picked up from this app. Otherwise, he's a pleasant guy to talk to and definitely knows his domain. My friend in IT, and probably his superiors in the company, want him out of the code. They view him as wasting his expertise on coding tasks he shouldn't be doing. My friend got me involved with a few small contracts which I handled without much problem - other than somewhat of a communication barrier with the domain expert. He explained the requirements very quickly, assuming prior knowledge of the domain which I do not have. This is partially his normal style, and I think maybe a bit of resentment from my involvement. So, I think he feels like the owner of the code and has entrenched himself in a development position. So... his coding technique. One of his latest endeavors was to make a page that only he could reach (theoretically - the security model for the system is wretched) where he can enter a raw SQL query, run it, and save the query to run again later. A report that I worked on had been originally implemented by him using 6 distinct queries, 3 or 4 temp tables to coordinate the data between the queries, and the final result obtained by importing the data from the final query into Access and doing a pivot and some formatting. It worked - well, some of the results were incorrect - but at what a cost! (I implemented the report in a single query with at least 1/10th the amount of code.) He edits code in notepad. He doesn't seem to know about online reference material for the languages. I recently read an article on Dr. Dobbs titled "What Makes Bad Programmers Different" - and instantly thought of our domain expert. From the article: Their code is large, messy, and bug laden. They have very superficial knowledge of their problem domain and their tools. Their code has a lot of copy/paste and they have very little interest in techniques that reduce it. The fail to account for edge cases, while inefficiently dealing with the general case. They never have time to comment their code or break it into smaller pieces. Empirical evidence plays no little role in their decisions. 5.5 out of 6. My friend is wanting me to argue the case to their management - specifically, I got this email from their manager to respond to: ...Also, I need to talk to you about what effect there is from Domain Expert continuing to make edits to the live environment. If that is a problem for you I need to know so I can have his access blocked. Some examples would help. In my opinion, from a technical standpoint, it's dangerous to have him making changes without any oversight. On the other hand, I'm just doing one-off contracts at this point and don't have much desire to get involved deeply enough that I'm essentially arguing as one of the Bobs from Office Space. I'd like to help my friend out - but I feel like I'm getting in the middle of a political battle. More importantly - if I do get involved and suggest that his editing privileges be removed, it needs to be handled carefully so that doesn't feel belittled. He is beyond a doubt the foremost expert on this system. I'm hoping this is familiar territory for some other stackechangers, because I'm feeling a little bewildered. How should I respond? Should I argue that he shouldn't be allowed to touch the code? Should I phrase it as "no single developer, no matter how experienced, should be working on production code unchecked"? Should I argue to keep him involved with the code, but with a review process? Should I say "glad I could help, but uh, I'm busy now!" Other options? Thanks a bunch!

  • Applying for MS CS with an un-related Bachelor's Degree [closed]

    - by yeenow123
    I received a BA in Economics and went to work and started developing a passion for programming while on the job. This lead to learning more and more about computer science in general. I want to go for a Masters in Computer Science. I'm taking courses at the local college to get some of the undergrad CS courses out of the way (Data Structures etc.). However I'm not sure what to focus on for my application. Should I take the GRE for CS? A lot of college application procedures recommend it if you didn't go to undergrad for CS. Should I try to improve my GRE general test? I took it a month after college ended and got mediocre scores, so I could definitely study a bit harder and improve my scores. Anything else that's necessary? My current job is not exactly in a related field, but I do get to do some programming/coding.

  • Aberdeen 10/25 Webcast: Service Excellence and the Path to Business Transformation

    - by Charles Knapp
    The uncertain economy has had a sustained impact on service organizations and processes. The impact has contributed to new complexities - new customer engagement channels, enhanced user and customer expectations, rapidly evolving technologies, increased competition, and increased compliance and regulatory mandates. Yet many organizations have embraced these challenges by investing in and transforming customer service to evolve, differentiate, and thrive under current constraints. What is their secret? Transforming Support Centers into Profit Centers According to the recent Aberdeen research report, “Service Excellence and the Path to Business Transformation”, service is now viewed as a strategic profit center at nearly 70% of organizations. As customers demand improved service, in terms of speed, efficiency and reliability, an organization's success has become increasingly dependent on optimizing the customer ownership experience. Those service organizations focused on providing easy, consistent, and relevant interactions across the customer lifecycle, including service and support delivery, are experiencing higher levels of customer acquisition and retention and are achieving better revenue and margin growth rates.  Don't miss this opportunity to learn how to transform to provide the next generation of service offerings.

  • WebFX: Running JavaFX as web page

    - by Bruno.Borges
    This weekend I wanted to learn JavaFX, so I decided to code an idea I had a few years ago when I first saw JavaFX Script. So I started coding a web browser that runs HTML with the awesome, HTML5 supported WebView. But this browser also offers one extra feature: it loads FXML files as if they were HTML. So instead of defining your web page with HTML and running with WebKit, you can define a web page with FXML+CSS+JS and run as a JavaFX application. The project is called WebFX and already has a prototype on GitHub. I also uploaded a video on YouTube demonstrating the idea. What do you think about using JavaFX in the future for web pages, instead of HTML?

  • Web api authentication techniques

    - by Steve
    We have a asp.net MVC web service framework for serving out xml/json for peoples Get requests but are struggling to figure out the best way (fast, easy, trivial for users coding with javascript or OO languages) to authenticate users. It's not that our data is sensitive or anything, we just want users to register so we can have their email address to notify them of changes and track usage. In our previous attempt we had the username in the URI and would just make sure that username existed and increment db tables with usage. This was super basic but we'd notice people using demo as a username etc so we need it to be a little more sophisticated. What authentication techniques are available? What do the major players use/do.

  • Managing time for success in the industry? [closed]

    - by nvillec
    So about a year ago I decided to pursue programming, specifically game development, as a career. I've always been a pretty avid gamer, from chucking turnips at Shy Guys' faces in the 90s, to downing Heroic Deathwing last week. Just recently though, I've been spending a LOT of time playing games and it's starting to show in my programming classes. Yesterday after a discouraging exam, I put my foot down and vowed to myself to keep the gaming:coding ratio in favor of the one that will hopefully pay the bills later on. I realize that knowing games well is a key part of being a good developer, but as I've been recently shown, there's a threshold of pixelated indulgence that must not be crossed if I'm ever going to land my dream job. I'm assuming many of you are quite enthusiastic about games as well. What advice would you give an aspiring programmer regarding time management? Thanks!! (Also, I'm brand new to Stack Exchange...if this belongs somewhere else, I'm happy to move it)

  • How was 20Q made?

    - by Dan the Man
    Ever since I was a kid, I've wondered how they made the 20Q electronic game. In this game, which is it's on device, you think of an object, thing, or animal (e.g. a potato or a donkey), once you mentally choose your thing, the device goes through a series of questions such as: Is it larger than a loaf of bread? Is it found outdoors? Is it used for recreation? For each of the questions you can answer yes, no, maybe, or unknown. The way I've always thought of it to work was with immense, nested conditionals (if statements). But, I don't think that would be very likely as it would be terribly difficult to understand while coding it. I'm not looking for a discussion as SE doesn't allow it; I'm looking for concrete knowledge or solutions.

  • AllSparkCube Packs 4,096 LEDs into a Giant Computer Controlled Display

    - by Jason Fitzpatrick
    LED matrix cubes are nothing new, but this 16x16x16 monster towers over the tiny 4x4x4 desktop variety. Check out the video to see it in action. Sound warning: the music starts off very loud and bass-filled; we’d recommend turning down the speakers if you’re watching from your cube. So what compels someone to build a giant LED cube driven by over a dozen Arduino shields? If you’re the employees at Adaptive Computing, you do it to dazzles crowds and show off your organizational skills: Every time I talk about the All Spark Cube people ask “so what does it do?” The features of the All Spark are the reason it was built and sponsored by Adaptive Computing. The Cube was built to catch peoples’ attention and to demonstrate how Adaptive can take a chaotic mess and inject order, structure and efficiency. We wrote several examples of how the All Spark Cube can demonstrate the effectiveness of a complex data center. If you’re interested in building a monster of your own, hit up the link below for more information, schematics, and videos.

  • New Bing Maps

    - by MikeParks
    Normally I don't stray too far from Programming and TFS on my blog posts but I'm just really impressed with how much Silverlight has improved Bing maps. I use to be big on MapQuest, then hopped over to Google, but now the new Bing Maps have everything I need. The two coolest features are right on the main page. All you have to do is go to http://www.bing.com/maps/explore/, enter your city and hit enter in the search box, then look in the lower left corner under the EXPLORE section. Check out the "What's nearby" and "Restaurants" links. The best part is, if you're interested in doing any Silverlight programming, they have a Bing Maps Silverlight Control Interactive SDK. I was thinking about coding something....but they've pretty much got it down :) Pretty impressive stuff.

  • What do you look for when debugging deadlocks?

    - by Michael K
    Recently I've been working on projects that heavily use threading. I think that I'm OK at designing them; use stateless design as much as possible, lock access to all resources that more than one thread needs, etc. My experience in functional programming has helped that immensely. However, when reading other people's thread code, I get confused. I am debugging a deadlock right now, and since the coding style and design are different from my personal style, I am having a difficult time seeing potential deadlock conditions. What do you look for when debugging deadlocks?

  • Deciding on a company-wide javascript strategy [on hold]

    - by drogon
    Our company is moving most of its software from thick-client winforms apps to web apps. We are using asp.net mvc on the server side. Most of the developers are brand new to the web and need to become efficient and knowledgeable at writing client-side web code (javascript). We are deciding on a number of things and would appreciate feedback on the following: Angular.js or Backbone.js? Backbone (w/ Underscore) is certainly more light weight, but requires more custom development. Angular seems to be a full-fledged framework, but would require everyone to embrace it and probably a longer learning curve(??). (Note: I know nothing about Angular at this point) Require.js or script includes w/ MVC bundleconfig? Require.js makes development "feel like" c# (importing namespaces). But, integrating the build/minification process can be a pain (especially the configuration). Bundling via mvc requires developers to worry more about which scripts to include but has less overall development friction. Typescript vs Javascript Regardless of frameworks, our developers are going to need to learn the basics. Typescript is more like c# and MAY be easier for c# developers to understand. However, learning TypeScript before javascript may hinder their mastery of javascript at the expense of efficiency.

  • Am I bored with programming? [closed]

    - by user1167074
    I have started programming 2 years back and I have learnt web programming while working for big corporate companies. I was very passionate and I even did couple of side projects which were well appreciated by my friends and colleagues. But for the past 2 months I am not doing anything really interesting with programming, even if I get good ideas I am not feeling like coding, sub consciously I am feeling like "So What?" if I do this project. I would like to know from the more experienced programmers if this is just a phase or am I really missing something? Thanks

  • Get collision details from Rectangle.Intersects()

    - by Daniel Ribeiro
    I have a Breakout game in which, at some point, I detect the collision between the ball and the paddle with something like this: // Ball class rectangle.Intersects(paddle.Rectangle); Is there any way I can get the exact coordinates of the collision, or any details about it, with the current XNA API? I thought of doing some basic calculations, such as comparing the exact coordinates of each object on the moment of the collision. It would look something like this: // Ball class if((rectangle.X - paddle.Rectangle.X) < (paddle.Rectangle.Width / 2)) // Collision happened on the left side else // Collision happened on the right side But I'm not sure this is the correct way to do it. Do you guys have any tips on maybe an engine I might have to use to achieve that? Or even good coding practices using this method?

  • Why is JavaScript not used for classical application development (compiled software)?

    - by Jose Faeti
    During my years of web development with JavaScript, I come to the conclusion that it's an incredible powerful language, and you can do amazing things with it. It offers a rich set of features, like: Dynamic typing First-class functions Nested functions Closures Functions as methods Functions as Object constructors Prototype-based Objects-based (almost everything is an object) Regex Array and Object literals It seems to me that almost everything can be achieved with this kind of language, you can also emulate OO programming, since it provides great freedom and many different coding styles. With more software-oriented custom functionalities (I/O, FileSystem, Input devices, etc.) I think it will be great to develop applications with. Though, as far as I know, it's only used in web development or in existing softwares as a scripting language only. Only recently, maybe thanks to the V8 Engine, it's been used more for other kind of tasks (see node.js for example). Why until now it's only be relegated only to web development? What is keeping it away from software development?

  • Continuous integration (with iOS and Android projects)

    - by paxx
    I'm trying to make some positive changes in my company and one of the changes is implementing continuous integration. We do mobile development (iOS/Android) so I need a CI that supports both types of projects. As you can tell I don't know a lot about CI but I've googled a little bit and I think that Jenkins and Hudson are the two most popular. I have a two part questions. Your thought on Jenkins and Hudson? Is there a way for CI to check if the project is compiling to the coding standards (like loose coupling and so on)?

  • If you develop on multiple operating systems, is it better to have multiple computers + displays?

    - by dan
    I develop for iOS and Linux. My preferred OS is Ubuntu. Now my software shop (me and a partner) is developing for Windows too. Now the question is, is it more efficient to have multiple workstations, one for each target OS? Efficiency and productivity is a higher priority than saving money. I have a 3.4Ghz i7 desktop workstation running Ubuntu and virtualized Windows with two displays, and I'm putting together an even more powerful i7 Hackintosh with 16GB RAM (to replace my weak 2.2Ghz i5 Macbook Pro). My specific dilemma is whether I should sell the first computer and triple boot on the second one, or buy two more displays and run both desktop systems simultaneously. Would appreciate answers from developers who write software for multiple OSes. Running guest OSes in VirtualBox on one system not ideal, because in my experience performance is seriously degraded under virtualization. So the choice is between dual/triple booting on one system vs having two systems, one for OSX+iOS/Windows (dual boot) and the other for Ubuntu (which I prefer to use as my main OS). For much of our work, I write a server-side application in Linux and a client for iOS (or for Windows or OS X) simultaneously.

  • Is it a good approach to rely on 3rd party software ( not library )?

    - by gunbuster363
    We have program using a call to a winzip program or 7zip commandline tool to zip some files. Once I accidentally uninstall winzip on my computer and making one of our program( created by the programmer already left ) crashed. So we cannot uninstall the winzip program. Now I've come to a point which I need to decide a external tool for gzip in windows or I make a java program which I can call to gzip the file. Obviously a external tool such as 7z is convenient and we can avoid some extra coding with java. On the contrary, if 7z is uninstalled accidentally, our program will crash. What do you think?

  • C: What is a good source to teach standard/basic code conventions to someone newly learning the language?

    - by shan23
    I'm tutoring someone who can be described as a rank newcomer in C. Understandably, she does not know much about coding conventions generally practiced, and hence all her programs tend to use single letter vars, mismatched spacing/indentation and the like, making it very difficult to read/debug her endeavors. My question is, is there a link/set of guidelines and examples which she can use for adopting basic code conventions ? It should not be too arcane as to scare her off, yet inclusive enough to have the basics covered (so that no one woulc wince looking at the code). Any suggestions ?
