• Free serif font with clearly distinguishable 0 (zero) character

  - by l0b0

  I'm using gLabels to create some small pieces of paper to give away to people - Just two lines of about 15-20 characters each. One of the important parts of the design is that there are no "o" ("oh") characters, but there are "0" ("zero") characters in an all-lowercase URL. Therefore I need a non-monospaced (and very legible in print) font where "0" cannot be confused with "o" even without reference. The closest thing I've found so far is Andale Mono and Inconsolata , but they are both monospace, and as such not very easy to read in print. Alternatively, to find a font myself, is there some way to preview all fonts in the Ubuntu repositories without installing them?

• SCRUM PREREQUISITES [closed]

  - by Ranna

  I have just started working as scrum-master for a small team. I am new for it. I have following doubts in my mind. I just wanted to know what are the pre-requisites that scrum-master should take care of? Why a scrum is called empirical process ? Do SCRUM only applies to a IT department related product planning ? How one can split User-Stories into sub-userstories ? And do scrum-master is responsible for that ? Is there any eligibility for being a scrum-master ? How one can acheive scrum-certification? Thanks in advance.

• Is there benifit to maintain a large project with bad code?

  - by upton

  I'm currently maintain a large project with more than 100000 LOC. The code use the MFC as its framework, in genral, it only has interface part which heavily use the mfc api and a business logic part which full of bad code, confusing logic. The company has some small features delivered to the customer each year(most features are adding code to exisiting project, finding some reference of some api or variable and it' s no different with fixing 3-4 bugs ), most of the tasks are to resove issue and optimize performance . Like other company with maintaining position, it value people who knows much logic about its product. There are people who can quickly finish the job on such project, is it worth to train myself like such a programmer? Is there benifits to work on such project for a long time?

• dbus error on 14.04 after system is left idle for a few hours

  - by user281513

  I did a clean install of 14.04 on a crucial M4 64gb ssd. The system boots in less than 30 seconds now! but.. when I leave it idle for a few hours and log back in nothing works .. if I do a simple command like df ..I get a dbus error message. I also have a toshiba sata disk mounted for general storage since the ssd is so small .. nothing appears to be damaged when I reboot but it is extremely annoying .. any ideas on how to correct this will be appreciated.

• Best platform for android and ios game?

  - by LoveMeSomeCode

  Ok, this has been asked before, but not recently, and most of the answers were just 'buy a mac'. So we're a couple guys who've been making small flash games, and now we want to go mobile, and there seem to be lots of options. Does anyone here have experience with one or more of these platforms to tell us the pros and cons of each? Corona AIR 3 Rhodes Could someone with experience compare and contrast these to each other and native development? We want to cast the widest net with the least re-work so we'd like to target just Android and iPhone, and we'd like it to be an actual app in the market instead of just a mobile website. We have experience in Actionscript, Javascript, and C#.

• Structuring an input file

  - by Ricardo

  I am in the process of structuring a small program to perform some hydraulic analysis of pipe flow. As I am envisioning this, the program will read an input file, store the input parameters in a suitable way, operate on them and finally output results. I am struggling with how to structure the input file in a sane way; that is, in a way that a human can write it easily and a machine can parse it easily. A sample input file made available to me for a similar program is just a stream of comma-separated numbers that don't make much sense on their own, so that's the scenario I am trying to avoid. Though I am giving the details of my particular problem, I am more interested in general input-file structuring strategies. Is a stream of comma-separated values my best bet? Would I be better off using some sort of key:value structure? I don't know much about this, so any help will probably put me in a better track than I am now.

• Inserting Data into a Microsoft SQL 2008 Database in ASP.NET 3.5

  In the previous article Creating an ASP.NET Dynamic Web Page using a MS SQL Server 2 8 Database GridView Display you learned how to create a dynamic web page that can let the user edit and delete database records directly using a web browser. It was demonstrated with a home renovation project where team leaders can update and delete project tasks online. However it does not include features that let users add or insert new records directly into the database using a web browser. This feature will be covered in this tutorial....

• ideas on multiplayer games which include lots of collaboration?

  - by user494461

  For my master thesis I wanted to design a small multiplayer game which includes more than one player(maybe 5), has 2-3 players collaborating at a time to achieve some task. The most important thing is realistic simulation of the movable objects in the scene which more than one player should simultaneously interact with. I would also prefer large virtual environments (VEs) like mmogs where groups of players are interacting in different areas of the VE. tasks for players should include 2-3 players touching movable objects at same time. e,g, a very basic task can be users lifting a cube together and pushing it through a hole I am not new to designing virtual environments with openGL, but have never designed games before and rarely play other than few of my favorite ones like Fifa. I wanted some ideas on what kind of games should I look at which should help me with ideas for my tasks for the users to gain points and win in games? any current indie games which might inspire me?

• As a Qt GUI programmer, how to improve (career & skill)?

  - by linjunhalida

  hello, I'm a python & Qt programmer, and my daily job is create small PC GUI programs ship with hardware devices. the problem is, My job is simple, read/write data to device by using serial port(pyserial), display and edit data(PyQt + PyQwt), that's all. although I'm a linux user, my program is running under windows XP, but thanks to PyQt, I can still develop under linux. And I'm always afraid of being replaced by the people cheaper and younger than me in the future. (I'm 26 now.. not too much time for playing..) So I need improve myself, and make me more competitive in the global market, and I like programming, and want coding till the end of my life. any roadmap suggestion?

• Scalability of multi-threading in game server

  - by Taylor Hill

  What is a reasonable number of threads for a simple 2D mmo in Java? Is it reasonable to have two threads per connection, one for the input stream and one for the output stream? The reason I ask is because I use a blocking method on the input stream, and a workaround seems unnecessarily complex if I were to try to get around it without adding threads. This is mostly for my own edification; I don't expect to have 5 million people playing it ever, or even 5, but I'm wondering what a good scalable solution is, and if this is reasonable for a small server (<30 connections).

• Architecting persistence (and other internal systems). Interfaces, composition, pure inheritance or centralization?

  - by Vandell

  Suppose that you need to implement persistence, I think that you're generally limited to four options (correct me if I'm wrong, please) Each persistant class: Should implement an interface (IPersistent) Contains a 'persist-me' object that is a specialized object (or class) that's made only to be used the class that contains it. Inherit from Persistent (a base class) Or you can create a gigantic class (or package) called Database and make your persistence logic there. What are the advantages and problems that can come from each of one? In a small (5kloc) and algorithmically (or organisationally) simple app what is probably the best option?

• Installing multi-boot Linux system

  - by user94924

  I have a dual (XP/Linux) boot Compaq Presario S4500UK with a couple of spare partitions on the boot drive which I want to use for testing different Linux distros/configs before installing them on "live" machines. I tried this with Oneiric which worked fine until I came to uninstalling the test system. Fortunately Oneiric uses Grub2 and so redirecting the bootloader to work from the original Linux partition was a piece of cake - if a bit annoying. I now need to do some tests on Hardy and DSL (Damned Small Linux), neither of which use Grub2. Question: Is it possible to install a test operating system without adding/replacing the bootloader (ie so I can still use Grub2 from the original partition with its nice interface and recovery facilities)? Is there another way of uninstalling/decommisioning a test OS which doesn't trash the boot loader? (The only way I know to do this is by deleting/reformatting the partition which takes with it the bootloader which is in that partition). Any help would be much appreciated. Tks jg1

• Podcast site - Serve audio files with CDN

  - by Bobe

  I am managing a small podcast website hosted on a shared server. Currently there are only eight or nine episodes, each of which are about 50 MB, so bandwidth is not really an issue at the moment. However, looking forward, would it be feasible to use a "free" CDN like Cloudflare to serve the audio files? If so, how would I set this up? I took a quick look at it before, and it seems you have to have your whole site routed (is that the right term?) through the CDN rather than just specific files or filetypes. I'd like some clarification on this.

• Is it possible to make the desktop background transparent or otherwise hidden?

  - by EndangeredMassa

  I'm running Ubuntu in a virtual machine via VirtualBox. I have the seamless mode turned on, which is pretty cool. However, if I move an Ubuntu window around quickly, I can see the redraw of the ubuntu background quickly before it's hidden by VirtualBox again. This isn't a huge deal, but I'd like to fix it, if possible. I see two possible options that don't involve changing VirtualBox code: 1. Make the Ubuntu desktop transparent 2. Make the Ubuntu desktop hidden entirely Is it possible to do either? I know that Compiz Fusion has/had a feature to do this for their cube effects, but I don't think that I can run this on the VM. And, even if I could, I don't want to run those services for this one small feature.

• How can you put all images from a game to 1 file?

  - by ThePlan

  I've just finished a basic RPG game written in C++ SFML, I've put a lot of effort into the game and I'd want to distribute it, however I've ran into a small issue. Problem is, I have well over 200 images and map files (they're .txt files which hold map codes) all in the same folder as the executable, when I look in the folder, it makes me want to cry a little bit seeing so many resources, I've never seen a game which shows you all the resources directly, instead I believe they pack the resources in a certain file. Well, that's what I'm trying to achieve: I'm hoping to pack all the images in 1 file (Maybe the .txt files as well) then being able to read from that file or easily add to it.

• Does anyone know of a simple (free?) feature request tracking system we could use internally for sales people?

  - by Ryan

  I sometimes hear about pain points of customers using our app from sales people, but there really isn't a good way for us to currently keep track of these. I was going to write one myself but figured I would ask first. I was thinking something so simple it would literally just be a small form for adding a new feature, and then it would appear in the list, like stackexchange questions. Then users can upvote them, or even record each time a user complains about something related to the request so we can order them in priority based on real data. Then I can easily go look every few days and see what's going on. That's really it, nothing more complicated than that. Know of anything?

• Releasing patches and updates to web service users

  - by Kalidoss.M

  I have written one web services using Java. Its already live (Up & Running). During development I have SVN(repository) + Jira for task maintenance + Maven for building the web services. Now i have some small update for my web services and i have created that task in Jira and committed the files in svn with respect to Jira-Id after all testing, etc.. Say my web services is used by 10 clients, we did not give our source code to them. Is there any steps/procedure available to release patch/updates? Is there any way to render/create the change log at the build time (maven). How do i manage the change log for all version or Patch updates during build time? (Automatically)

• Failed to allocate memory - What is it trying to say?

  - by asprin

  In my early days of programming I often used to get memory related fatal errors in the following format: Fatal error: Allowed memory size of <some big number> bytes exhausted (tried to allocate <some small number> bytes) in /path/to/filename.php on line <some line number> I'm a little embarrassed to state that even though I have figured out how to solve them and take steps to avoid them altogether, I'm still not quite sure what exactly does the message translate to in simple words. For example, if I get a message such as: Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 4000 bytes) in ........ on line 34 As things stand at the moment, I assume it to be stating that the script consumes 67108864 bytes of data, but only 4000 bytes are available during runtime. Am I right in my assumption? If not, what's the correct interpretation?

• If I am in the USA, should I not have a hosting provider in another country? [on hold]

  - by johnny

  I saw the various questions on SO about this. I'm not sure they answered me. I'm in the USA. Someone asked me about hosting on a company in South Africa. They are not a big company. This person simply liked the company for whatever reason. I only saw one horror story. Not many reviews really. It is a small outfit from what I can tell. But, the fact of it being in South Africa, does that matter? Do people ever pursue legal action against hosting companies anyway? The users will all be in the States. edit: I'm not sure why this is unclear.

• Tile transitions - external vs internal

  - by omgnoseat

  I've been looking at a couple of games and noticed that the transitions between tiles are handled somewhat different. I was wondering which methods are to be used in different situations and why. I'm currently using internal edges in a top-down game, and it's working out so far. But I don't want to run into problems later on, and have to redo the whole tileset. I noticed that platforming games mostly use the internal edges, and top-down games mostly use external and hybrid transitions. I can see how these tiles are used to create "depth" in top-down games, where the player apears to be standing in front of a wall for example. But it seems unlikely that such a small feature decides the entire method for tile transitions. You could always alter the bounding box to create the same effect.

• CPU spikes cause audio stuttering in Audacious when browsing? (Lubuntu)

  - by Alucai Vivorvel

  My default audio player is Audacious, browser Google Chrome. I tried Firefox, and while I love it, the CPU load spikes when doing something as simple and small and switching a tab, which causes the audio playing to stutter (as sound is onboard and handled thru the CPU). Chrome doesn't do this as much, but there is the occasional stuttering when browsing, which is ridiculous, as not even Windows Vista does this. So I thought maybe it's something to do with how Lubuntu handles sound, I checked and only ALSA was installed. I tried installing PulseAudio, but, while the music "plays", nothing comes through the speakers. Immediately after switching back to ALSA the music pours out of them. So I was wondering if you had any idea what was going on here. I asked on Ubuntu Forums but apparently my problem is too complex, as it's been over a week since the last reply. Specs are: AMD Athlon 64 3200+ @ 2GHz 2GB Corsair 667MHz DDR2 RAM ATi HD Radeon 3650 (AGP) 512MB 500W Cooler Master PSU 80GB SATA II HDD (Vista is installed on 500GB drive) Biostar K8M800 Motherboard

• Am I personally liable for bugs in medical software I've developed as an employee? [closed]

  - by user466406

  Some background: I'm employed at a small, Australia-based web agency that is dipping it's toe into Mobile Application development (iOS). The project that I'm working on provides a way for users to save medication dosage information which is sync'd with a backend server. Users must agree to ToS, Disclaimer etc before using the application. This is my first iOS application, and the project is currently over budget. As a result, management is not devoting the resources to Q&A and is pushing instead for more features. I am an employee of the agency, that has been contracted by a non-for-profit. The application will probably be released under our agency's name, but we also have the option of releasing it as the not-for-profit. My question is, if there are bugs found in the application, and as a result a user takes an incorrect dosage of a medication, am I personally liable? Is there anything that I can or should do in order to protect myself personally?

• Distorted graphics, problems with starting up

  - by GreenEggsAndHam64

  Using the newest version of Ubuntu, freshly installed. NVIDIA GeForce GTX 560 Ti. It's mostly the font that doesn't render well, I think. Small logos do it too, sometimes. Screenshot to clarify (see bookmarks, search bar, etc.). EDIT: Another screenshot. And, sometimes when I start up, I get only a black screen saying [OK]. I can move my mouse around, but nothing helps, except for restarting. Also, my desktop picture doesn't stay the same. Every time I start up Ubuntu it goes back to the standard purple background. They're not very serious problems, but it's all a little annoying. Thanks in advance for your help.

• Improve Bad testing

  - by SetiSeeker

  We have a large team of developers and testers. The ratio is one tester for every one developer. We have full bug tracking and reporting systems in place. We have test plans in place. Every change to the product, the testing team is involved in the design of the feature and are included in the development process as much as possible. We build in small iterative blocks, using scrum methodology and every scrum they are included in, including the grooming sessions etc. But every release of the product, they miss even the most simple and obvious defects. How can we improve this?
