• Object Oriented programming on 8-bit MCU Case Study

  - by Calvin Grier

  I see that there's a lot of questions related to OO Programming here. I'm actually trying to find a specific resource related to embedded OO approaches for an 8 bit MCU. Several years back (maybe 6) I was looking for material related to Object Oriented programming for resource constrained 8051 microprocessors. I found an article/website with a case history of a design group that used a very small RAM part, and implemented many Object based constructs during their C design and development. I believe it was an 8051. The project was a success, and managed to stay inside the very small ROM/RAM they had available. I'm attempting to find it again, but Google can't locate it. The article was well written, and recommended a "mixed" approach using C methods for inheritance and encapsulation - if I recall correctly. Can anyone help me locate this article?

• cannot use sudo on ubuntu server passwordless authentication?

  - by Lucas Crijns

  Hello I'm new at the forum and I want to introduce myself: I'm Lucas Crijns and I'm a very happy user of ubuntu server. I was reading about passwordless authentication with ssh. So I made a key and published it to ubuntu server, it worked well and I could login with my private key. But then I locked the account to prevent hacking from my password. After I ran "passwd -l lucas", I was not longer able by my next login to use sudo. Because it was asking for a password and I locked it. I was thinking that sudo would also be without a password. My question is now: is it possible to use sudo? And how can I enable it without a valid password for sudo? Thank you for your help!

• Global menu stopped working for most applications

  - by ltorgo

  I have Ubuntu 12.04 32 bits and I had been enjoying global menus and HUD since the beginning. However, for some strange reason, I stopped having global menus for most applications and thus no HUD fun anymore. Actually, the only two applications where I continue to have global menus are Thunderbird and Firefox, so not sure if it has something to do with these two... I've already browsed through some similar reports and already tried the following: checking if indicator-appmenu was installed. tried to use Unsettings to switch on and off, with reboots in the middle, global menus. logged in with a different user to see if it was some configuration of my user. also checked, using dconf-editor that, com ? canonical ? indicator ? appmenu ? menu-mode = "global" Any hint/help would be appreciated! Thank you in advance

• Ubuntu does not recognized local webserver

  - by Syed Khalil-ur-Rehman

  My Internet Cable provider has set up a web server which hosts different entertainment material like movies, songs, tv shows and games etc. While using windows the pc recognises it as a local web server and downloads files with full LAN speed of 10 mb per second. On the contrary when using Ubuntu I am only able to download the files on my Internet speed not more than 100 kb per second. What ever I try ubuntu does not recognizes the webserver as a local area network web server but as a normal internet website. How to make Ubuntu download files from this server with full LAN speed. Please help in this regard.

• Aser Aspire 3690 WIreless Not working, new Ubuntu user

  - by drew

  I don't know that much about Ubuntu, but I put it on an Acer Aspire 3690 Laptop (replaced Win Vista). Everything seems to work fine, but the wireless connection. It says "FIRMWARE MISSING". It detects that I have a wireless card, so I don't know what to do. I've already used the "ADDITIONAL DRIVERS" thing, and that didn't work. I've googled and have not found anything helpful. I don't really know what I'm doing, so can your directions please be kindergarden level? Thank you very much for any help you can provide. I really appreciate it.

• DNS query re website Status: inactive

  - by Matthew Brookes

  There is a website that I am assisting with which, when you do a DNS look up on Who.is, returns a Website Status of "inactive". I also noticed the server type is incorrectly reported. This is not a website I generally use for DNS queries so am unsure if it is reliable. Using other DNS checking services reports what Iwould expect and the site is functioning correctly. Research I have done with regard to Website Status: inactive suggests an issue with the DNS configuration? I am looking for help understanding if this is something to be concerned with and if possible how to update this value or how it gets set in the first place.

  - by Luuz

  I'm using ubuntu 11.10 and in the update manager I have a message that says package information last updated 59 days ago press the check button to check for software updates I do that, but i'm up to date. I checked other threads with this same problem, and saw i should do sudo apt-get update in a terminal to see which repository is not up to date and when I did, I got this message: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/oneiric/Release Then I checked for this repository in software sources but couldn't find this specific one. In my /etc/apt/sources.list.d I have only one line: deb http://archive.canonical.com/ubuntu oneiric partner #Added by software-center So now I don't know what to do more. Should I upgrade to 12.04 and will it solve my problem? I wouldn't want to upgrade if there is a problem in the last version but I don't know much about Ubuntu so, can anyone help me please? Thank you!!

• Philly GiveCamp 2010

  - by wulfers

  Spent the weekend helping out several non-profits doing what we like to do best...  Designing, developing and making people very happy with their new websites, systems, applications and features.  Form what I saw at this GiveCamp about 75 percent of the non-profits needed updated or new websites supporting CMS features and the ability for staff members to update the content on their websites.... Some cool apps were designed and developed..... A centralized system for distribution of daily schedules and task assistance to autistic clients was a show stopper with an awesome central management interface, IPhone and in the future windows phone support for tactile, auditory and visual cues. SharePoint was upgraded and forms were automated for a volunteer fire company that desperately needed some automation to help the fireman do their primary job. Many cool sites for non-profits that had ether an outdated or non existent web presence.

• Fundamental programming book [closed]

  - by Luke Annison

  I'm a fairly new programmer and currently learning ruby on rails with the intention of developing a web application. I am currently going reading Agile Web Development with Rails 4th Edition and its working well for me, however I'm wondering if somebody can recommend a more general, almost classic book to read casually alongside to help cement the fundamentals in place. As I said, I'm for the most part a beginner and the only education I've had is this and briefly one other technical book, so I'm sure there must be some "must reads" out there that give me a more substantial context for the basics of either Ruby on Rails, Ruby, objective oriented programming, or programming in general. What books helped you grasp a deeper and more rounded understanding of your skills as a programmer? All suggestions are welcome and appreciated.

• Desktop top is lower than it should be

  - by Idan Arye

  I have a very odd problem with Ubuntu 11.10. Here is a picture of it: The window in the picture is maximized, but for some odd reason it does not cover the entire desktop area. That area of the desktop the window does not cover is a dead area - I also can't drag desktop items to there, though I can drag not-maximized windows to that area. Rebooting doesn't help. The problem started after I configured some windows partitions to automount on startup(though I don't see how that could cause the problem...) Does anyone know a way to fix this?

• Feeling a bit... under-challenged in my university course

  - by Corey

  I'm currently a sophomore at my university, majoring in Computer Science. Obviously, there are some programming courses as part of my curriculum. However, I'm feeling very underwhelmed by its progress. I've self-taught myself a lot and like to code in my spare time as a hobby. I'm currently in Computer Science II. I never took CS 1 because it seemed rather basic -- I asked someone in the department if they would override my CS 1 requirement if I passed their final (which I did with flying colors). Anyway, the class is going by quite slowly. It seems like the rest of the class has a hard time understanding some basic concepts, which the professor needs to keep going over to help them understand. Is this normal? Looking at the class schedule, I seem to know everything except for one or two things near the very end of the semester. Is there a different perspective I can look at this through so it doesn't seem so boring?

• Is it normal to not have desktop effects after installing on an Asus N53S?

  - by Fabzter

  I've just installed 11.10 and so far so great, except I just discovered (after looking at another installation) I'm missing some effects. First of all, I am using unity 3d (I chose ubuntu at the login menu), and have already the correct nvidia drivers. Yet, my launcher is the same from unity 2d, the same as the app switcher, and when dragging windows to screen corners, they don't get grabbed. This "error" was present since the begining, so I was not able to detect it. Please help, I want to have an ubuntu experience as nice as everyone else. EDIT 1: I'm using an Asus N53S. My graphic card is Nvidia geforce GT540M. It says cuda, if that matters.

• PHP developer wanting to learn python

  - by dclowd9901

  I'm pretty familiar at this point with PHP (Javascript, too), up to the point of OOP in PHP, and am looking to branch out my knowledge. I'm looking at Python next, but a lot of it is a bit alien to me as a PHP developer. I'm less concerned about learning the language itself. I'm positive there's plenty of good resources, documentation and libraries to help me get the code down. I'm less sure about the technical aspects of how to set up a dev environment, unit testing and other more mundane details that are very important, aid in rapid development, but aren't as widely covered. Are there any good resources out there for this?

• Learning the command line [duplicate]

  - by Billy

  This question already has an answer here: What is the best way to learn how to use Ubuntu with terminal? 3 answers This isn't really a technical question but I am curious as to how long it takes to learn the linux command line. I would like to learn how to be able to do as much as possible easily from the command line. I just bought a book, linux command line and shell scripting bible. I know that this book will be of great help, but i just have no clue how long it will be before i can successfully naviagte the terminal with ease. If you could post and let me know about your experience with the terminal, and the learning process, that would be greatly appreciated. Thank you in advance.

• bash-completion for xelatex

  - by andreas-h

  I'm on Ubuntu 12.04. When using bash as my shell, I can just type latex my_do <TAB> to compile a file my_document.tex, as *bash_completion* does the auto-complete. However, this auto-completion does not work for the xelatex executable. So I would like to add the same auto-complete functionality for xelatex as exists for latex. I could find that the latex auto-complete feature comes from the file /etc/bash_completion, where I could find a line complete -f -X '!*.@(?(la)tex|texi|dtx|ins|ltx)' tex latex slitex jadetex pdfjadetex pdftex pdflatex texi2dvi Now I could of course just add xelatex to that line and everything is fine. However, I'm wondering if I could instead put a file in /etc/bash_completion.d, as this would leave the system file untouched. Unfortunately, I'm at a complete loss about the syntax -- but maybe someone can help me here?

• Thank You For Visiting Us At Oracle OpenWorld And JavaOne

  - by Brandye Barrington

  Thanks to everyone who visited us at the Oracle OpenWorld and JavaOne conferences last week. We always enjoy putting faces with names and meeting those of you who are certified or are interested in Certification. Personally, I spent my week on sunny Taylor street at the Java Certification Zone in Taylor Street Cafe.  I talked to over 100 people last week about certification and handed out over 65 ribbons. The Oracle Certification Lounge at OpenWorld, at Moscone South enjoyed more than 200 visitors over the week. Both locations offered scheduled speakers and available experts, in addition to answers to all of your certification questions and account help when needed. We look forward to this opportunity every year to connect with you face to face. If you didn't make it out this year, we hope to see you next year - perhaps we will be so lucky as to enjoy another unseasonably warm week in San Francisco! Stay tuned to our blog for some customer success stories that we were able to record last week.

• Rendering performance in FlasCC + UDK when compared to Stage3d and UDK on Windows?

  - by Arthur Wulf White

  Adobe recently released the Flash C++ Compiler, which UDK uses to target Flash Player. Developers can now access UDK for browser applications. Does this mean greater performance than using a Stage3D engine (Away3D 4) and how much of a noticeable difference in performance would it make in rendering speeds? Is there any benchmark you could propose that would allow to compare them fairly? I am asking this to help myself understand the consequences in performance for deciding to use UDK in a browser based game. I would also like to know how it compares with UDK running natively in Windows? I am not asking which technology to use or which is better. Only interested in optimizing rendering speed in a 3d browser game with flash.

• Resources for 2D rendering using OpenGL?

  - by nightcracker

  I noticed that there is quite some difference between 3D and 2D rendering using OpenGL, the techniques are different - pixel-perfect placing is a lot more desirable, among other things. Are there any good (complete) references on using OpenGL for rendering 2D graphics? There are quite a few "tutorials" around on the net that help you open a window, set up a half-decent environment and draw a sprite, but no real good information on rotation, blending, lightning, drawing order, using the z-buffer, particles, "complex" primitives (circles, stars, cross symbols), ensuring pixel-perfect rendering, instancing and many other staple 2D effects/techniques. Any books, great blogs, anything? Any particular awesome libraries to read?

• Making fonts render similarly across browsers

  - by Zach L.

  I am building a website for a client, and we had hoped to use plain text, not images in the navigation bar. The font we are using is Century Gothic (I believe that this font is available on the majority of PCs and Macs) The problem is, that on different browsers the font renders significantly differnt. In Chrome we got it looking the way we want, but in firefox the text is smaller and bolder. Aside from writing browser specific javascript to alter the font properties, are there any other options to standardize the way the fonts are rendered cross-browser. Perhaps some library or API? Maybe its a matter of being more specific in declaring font properties? Honestly I am stuck and need help.

• 2 google analytics profiles for 2 sections of the same site

  - by sam

  Ive got a website which for the most part is a portfolio, there is another section of the site mysite.com/micro-site which ranks extremely well for it chosen term / topic, and brings in lots of traffic, but actually has little to do with the core business. It was really made as a piece of content - in the same way sites like this are - http://chrome.com/campaigns/rollit For the main site i use 1 Google analytics profile and set of tags, for the micro site i have a completely different analytics profile and set of tags. The main reason ive done this is because the traffic stats and insights for the micro site are essentially just noise, its nice to have the traffic but they dont help when reading analytics reports, so if they were combined my analytics reports would be a mess. Is there any disadvantage / negatives of doing this ?

• How do I go about hosting facebook apps that are picking speed?

  - by Karthik

  My situation is this. I coded in php and built a facebook app. After 3 days it has 13,000 users. I have my own server at hostmonster. It is a regular plan costing me about $70 per year. It has unlimited bandwidth. I did not anticipate hosting apps or that it could pick up so many users. Already 1 Gb of data was transferred in the last few days. I am planning to build a few more apps(around 10 - 20) and reach atleast a million users in total. Should I continue hosting on the same server or move to a VPS? I am a student and I don't have too much of a disposable income. So I want to move only if it is necessary. Right now it shows 1 Gb/infinity in data transfer. Any help/suggestions highly appreciated.

• 2D isometric: screen to tile coordinates

  - by Dr_Asik

  I'm writing an isometric 2D game and I'm having difficulty figuring precisely on which tile the cursor is. Here's a drawing: where xs and ys are screen coordinates (pixels), xt and yt are tile coordinates, W and H are tile width and tile height in pixels, respectively. My notation for coordinates is (y, x) which may be confusing, sorry about that. The best I could figure out so far is this: int xtemp = xs / (W / 2); int ytemp = ys / (H / 2); int xt = (xs - ys) / 2; int yt = ytemp + xt; This seems almost correct but is giving me a very imprecise result, making it hard to select certain tiles, or sometimes it selects a tile next to the one I'm trying to click on. I don't understand why and I'd like if someone could help me understand the logic behind this. Thanks!
