  • How do I return a purchase from the Ubuntu Software Centre?

    - by Garry Cairns
    I purchased Amnesia (game) from the Ubuntu Software Centre. It crashes on startup every time and I therefore want to return it for a refund. I can't find a way of doing so through the USC and, strangely, I can't find any trace of this having been asked before (maybe bad googling on my part). So the question is: how do I return a purchase and get a refund through the USC? EDIT Installing proprietary driver for AMD catalyst fixed Amnesia, but I still think this is an important question because it's basic customer service for any purchase. I'd therefore appreciate any answers anyone can find and I will continue to look too. If I find the answer I'll post it here.

  • How does PhP internally represent string?

    - by Jim Thio
    UTF8? UTF16? Does the string in PhP also keep tracks the encoding used for that string? A good answer would give me a sample of Let's look at this script for example. Say I do $original = "??????????????"; What actually happen? Obviously I think $original will not contain just 7 characters. Those glyps must each be represented by several bytes there. Then I do $converted= mb_convert_encoding ($original , "UTF-8") What will happen to $converted? How will $converted be different than $original? Will it be just the exact same byte sequence with $original but with different encoding? Or what?

  • Copyrighting software, templates, etc. under real name or screen name?

    - by Abluescarab
    My question is hopefully simple--should I copyright my work (art, software, web design, etc.) under my real name or my screen name? My real name and screen name are also easily connected with a bit of searching, so does it really matter in the end? I'm not a professional (at this point). I read this article: Is it a bad idea to sell Android apps in the Android Market under your real name? and they recommended releasing on the app market under a company name. I also read this article: On what name should I claim copyright in open source software?, but that didn't answer my question. I know it probably matters for big projects, but for little projects, does it matter? Thanks ahead of time!

  • Is it a bad practice to include all the enums in one file and use it in multiple classes?

    - by Bugster
    I'm an aspiring game developer, I work on occasional indie games, and for a while I've been doing something which seemed like a bad practice at first, but I really want to get an answer from some experienced programmers here. Let's say I have a file called enumList.h where I declare all the enums I want to use in my game: // enumList.h enum materials_t { WOOD, STONE, ETC }; enum entity_t { PLAYER, MONSTER }; enum map_t { 2D, 3D }; // and so on. // Tile.h #include "enumList.h" #include <vector> class tile { // stuff }; The main idea is that I declare all enums in the game in 1 file, and then import that file when I need to use a certain enum from it, rather than declaring it in the file where I need to use it. I do this because it makes things clean, I can access every enum in 1 place rather than having pages openned solely for accessing one enum. Is this a bad practice and can it affect performance in any way?

  • What are the files in /dev/input/ and what they do?

    - by Pouya
    I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

  • Banshee won't sync OGG format to my iphone

    - by Daze
    I have a jailbroken iphone 3g with 16 gigs of memory and I've been putting my music on it from banshee lately and have been having almost no issue. Unfortunately, I just added a few albums to my Banshee library and tried to sync them to my iphone, but every time I try, i see a hundred or so errors saying that the device doesn't support the ogg format and there was no converter found. I'm still pretty much a newb at this stuff, so please help me and dumb down your answer. I'm running 12.04 and again, using an iphone 3g with no sim card, but it's been jailbroken and is used primarily for it's music function.

  • Bug Tracking Etiquete - Necromany or Duplicate?

    - by Shauna
    I came across a really old (2+ years) feature request issue in a bug tracker for an open source project that was marked as "resolved (won't fix)" due to the lack of tools required to make the requested enhancement, but since the determination was made, new tools have been developed that would allow it to be resolved, and I'd like to bring that to the attention of the community for that application. However, I'm not sure as to what the generally accepted etiquette is for bug tracking in cases like this. Obviously, if the system explicitly states to not duplicate and will actively mark new items as duplicates (much in the way the SE sites do), then the answer would be to follow what the system says. But what about when the system doesn't explicitly say that, or a new user can't easily find a place that says with the system's preference is? Is it generally considered better to err on the side of duplication or necromancy? Does this differ depending on whether it's a bug or a feature request?

  • How can I work out how many IP addresses there are in a given range?

    - by Jarede
    I'm wondering if there is a formula to work out the amount of IP addresses in a given range. I have a system that takes either a single IP address or a start and and end IP address: A single one might be: 145.16.23.241 A range might be: 145.16.23.122 - 145.16.23.144 The people inputting these aren't technical, nor are they receiving these details from technical people, so suggesting using CIDR notation isn't an answer for me. I want to be able to highlight that when entering a range such as: 122.100.10.12 - 128.10.200.140 it might not actually be a range and rather 2 singular IP addresses since such a range would comprise of x (large number of) IP addresses. Is there a basic formula to help me highlight this?

  • How do you select the fastest mirror from the command line?

    - by Evan
    I want to update my sources.list file with the fastest server from the command line in a fresh Ubuntu Server install. I know this is trivially easy with the GUI, but there doesn't seem to be a simple way to do it from from the command line? There are two different working answers to this question below: Use apt-get's mirror: method This method asks the Ubuntu server for a list of mirrors near you based on your IP, and selects one of them. The easiest alternative, with the minor downside that sometimes the closest mirror may not be the fastest. Command-line foo using netselect Shows you how to use the netselect tool to find the fastest recently updated servers from you -- network-wise, not geographically. Use sed to replace mirrors in sources.list. The other answers, including the accepted answer, are no longer valid (for Ubuntu 11.04 and newer) because they recommended Debian packages such as netselect-apt and apt-spy which do not work with Ubuntu. Use sed to replace mirrors in sources.list sudo sed -i -e 's#us.archive.ubuntu.com/mirror.math.ucdavis.edu#g' /etc/apt/sources.list

  • Can a language support something like "Retry/Fix"?

    I was just wondering if a language could support something like a Retry/Fix block? The answer to this question is probably the reason it's a bad idea or equivalent to something else, but the idea keeps popping into my head. void F() { try { G(); } fix(WrongNumber wn, out int x) { x = 1; } } void G() { int x = 0; retry<int> { if(x != 1) throw new WrongNumber(x); } } After the fix block ran, the retry block would run again...

  • Context is Everything

    - by Angus Graham
    Normal 0 false false false EN-CA X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} Context is Everything How many times have you have you asked a question only to hear an answer like “Well, it depends. What exactly are you trying to do?”.  There are times that raw information can’t tell us what we need to know without putting it in a larger context. Let's take a real world example.  If I'm a maintenance planner trying to figure out which assets should be replaced during my next maintenance window, I'm going to go to my Asset Management System.  I can get it to spit out a list of assets that have failed several times over the last year.  But what are these assets connected to?  Is there any safety consequences to shutting off this pipeline to do the work?  Is some other work that's planned going to conflict with replacing this asset?  Several of these questions can't be answered by simply spitting out a list of asset IDs.  The maintenance planner will have to reference a diagram of the plant to answer several of these questions. This is precisely the idea behind Augmented Business Visualization. An Augmented Business Visualization (ABV) solution is one where your structured data (enterprise application data) and your unstructured data (documents, contracts, floor plans, designs, etc.) come together to allow you to make better decisions.  Essentially we're showing your business data into its context. AutoVue allows you to create ABV solutions by integrating your enterprise application with AutoVue’s hotspot framework. Hotspots can be defined for your document. Users can click these hotspots to trigger actions in your enterprise app. Similarly, the enterprise app can highlight the hotspots in your document based on its business data, creating a visual dashboard of your business data in the context of your document. ABV is not new. We introduced the hotspot framework in AutoVue 20.1 with text hotspots. Any text in a PDF or 2D CAD drawing could be turned into a hotspot. In 20.2 we have enhanced this to include 2 new types of hotspots: 3D and regional hotspots. 3D hotspots allow you to turn 3D parts into hotspots. Hotspots can be defined based on the attributes of the part, so you can create hotspots based on part numbers, material, date of delivery, etc.  Regional hotspots allow an administrator to define rectangular regions on any PDF, image, or 2D CAD drawing. This is perfect for cases where the document you’re using either doesn’t have text in it (a JPG or TIFF for example) or if you want to define hotspots that don’t correspond to the text in the document. There are lots of possible uses for AutoVue hotspots.  A great demonstration of how our hotspot capabilities can help add context to enterprise data in the Energy sector can be found in the following AutoVue movies: Maintenance Planning in the Energy Sector - Watch it Now Capital Construction Project Management in the Energy Sector  -  Watch it Now Commissioning and Handover Process for the Energy Sector  -  Watch it Now

  • What zoomable image viewers are there for websites?

    - by tog22
    What zoomable image viewers are there? By these I mean tools that one can embed in a website to let a user zoom in on and pan around a high res image, a canonical example being http://www.zoomify.com/ (see the demo on their home page). Comments on them are welcome. I'm personally looking for something simple and cheap/free which ideally doesn't require Flash, and will accept the answer that comes closest to these requirements. But others who find this question may have different requirements, so all suggestions will be helpful. I have of course searched; I've found Zoomify, http://www.openzoom.org/ and http://code.google.com/p/galapix/ but none seem to meet my requirements, though I could be wrong and others may have more expert comments on these.

  • From Imperative to Functional Programming

    - by user66569
    As an Electronic Engineer, my programming experience started with Assembly and continue with PL/M, C, C++, Delphi, Java, C# among others (imperative programming is in my blood). I'm interested in add to my previous knowledge, skills about functional programming, but all I've seen until now seems very obfuscated and esoteric. Can you please answer me these questions? 1) What is the mainstream functional programming language today (I don't want to get lost myself studying a plethora of FP languages, just because language X has the feature Y)? 2) What was the first FP language (the Fortran of functional programming if you want)? 3) Finally, when talking about pure vs. non pure FP what are the mainstream languages of each category? Thank you in advance

  • Bad idea to display mail server info in public github project?

    - by kentcdodds
    I have the project for work that requires me to send e-mails to people using our work mail server. The server doesn't require authentication. Part of my project is using a Java-Helper I'm developing on GitHub. I don't know if I completely understand how it all works, but I'm guessing it would be a bad idea to have the server information available on GitHub for the world to see. Is this correct? After thought: I'm not going to put it in the Java-Helper because that wouldn't be helpful for anyone but me. but I'm still curious to know the answer to this question :) Thanks!

  • How to properly express programming proficiency in CV?

    - by Pouya
    I'm rewriting my CV and I have a very hard time to express my programming skills in an honest matter while not underrating myself. How would you classify programming skill in four or five levels from complete beginner to god-like? For sake of argument, let us consider C++. What words would you use to present your programming skills? For example who is an expert in C++ or which word has a higher impact: Expert vs. Experienced? Could you suggest me 5 words like above in ascending order? P.S. I was planning to ask this question in Academia.SE, however, at the end I realized that I want to know programmers answer to the question.

  • 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.

  • What's the recommended way of doing a HUD for an android game?

    - by joxnas
    Basically the question is in the title. I'm creating a RTS game and I will need buttons like attack move / attack ground, etc. I am not using any engine. When people do games in OpenGL for android (my case), do they ever use android components to control the game or do they create their components in the game? What are the general recommended approach, if there's any? How about more complex components like scrolling lists of items , etc? I would also appreciate you to pair your answer with a brief comment about how was your experience using the approach(es) you describe. Thanks :)

  • Are there any free hit counters that don't track users?

    - by David Englund
    Are there any free services that increment a simple hit counter without tracking the users of the site? I would like to know how many visitors there are to my site, excluding bots. I don't need detailed information like unique visitors or where the user is from (in fact, that's exactly what I don't want). I have been researching free hit counters, and it seems that most (all?) of them display advertisements and their terms of service indicate that they can use the data they collect from the client site however they want. Google Analytics also does this and tracks users across sites. The site is static HTML, so an external link or iframe of some sort is easiest for me to implement. I could switch to a Ruby or Node.js back-end, in which case lots of other options open up (like Ruby impressionist and more low-level implementations), but my hosting service is pretty limited. If the answer to my question is simply "no," what are my other options?

  • How many achievements should I include, and of what challenge?

    - by stephelton
    I know this question is fairy broad and subjective, but I'm wondering if there's been any published research into what an optimal number of achievements is and what kind of challenge they should present. The game this question directly relates to is a shoot-em-up, but an ideal answer is fairly theoretical. If there are there are too few achievements, or they are not challenging, I would expect they would fail in their goal to keep people playing. If there are too many, or they are unreasonably difficult, I would expect people to quickly give up. I personally witnessed the latter happening in Starcraft 2; a section of the achievements would have you win hundreds of games against their AI opponents (boring!)

  • How to manually detect deadlocks

    - by Dawson
    I understand the concepts of deadlock well enough, but when I'm given a problem like the one below I'm not sure how to go about solving it. I can draw a resource allocation graph, but I'm not sure how to solve it from there. Is there a better more formal way of solving this? Consider a system with five processes, P1 through P5, and five resources, R1 through R5. Resource ownership is as follows. • P1 holds R1 and wants R3 • P2 holds R2 and wants R1 • P3 holds R3 and wants R5 • P4 holds R5 and wants R2 • P5 holds R4 and wants R2 Is this system deadlocked? Justify your answer. If the system is deadlocked, list the involved processes.
