  • Is perfectionism a newbie's friend or enemy? [closed]

    - by Akromyk
    Possible Duplicate: Where do you draw the line for your perfectionism? I see that the development community is very focused on doing things the right way and personally I would like to do the same too, however, is it a good or bad idea for a newbie to focus on design principles, design patterns, and commenting code when getting started, or is it better to let creativity run wild and potentially write sloppy code. Where should a newbie draw the line?

  • No GUI, only CLI is working

    - by srinivas
    Right now I'm working on I.MX53 Quick Start Board for which has provided me the eu-boot kernel image with it and Android rootfs. It is working fine. The problem is when I am trying to change the rootfs with Ubuntu, I am able to use CLI with all 6 terminals working but no GUI is working. I tried many versions of rootfs like Ubuntu 11.10, 12.04 and core etc. Everything with the same result. Please help me.

  • What happens when you delete all the start screen tiles?

    - by TechTwaddle
    Note: I am currently in the process of relocating my blog from http://www.geekswithblogs.net/techtwaddle to my new address at http://www.techtwaddle.net I suggest you point your feed readers to the new address as I slowly transition to my new shared-hosted, ad-free wordpress blog :)   Well, the start screen disappears and all you see is the application list, which normally shows up when you scroll to the right. Pretty interesting I thought. So the start screen is basically a shortcuts screen on steroids, much nicer looking and with tile notifications.

  • New computer hangs on shutdown/reboot, how to troubleshoot?

    - by Torben Gundtofte-Bruun
    My system is working perfectly but it freezes during shutdown/reboot/suspend/hibernate: All windows and the menu bar disappear but the desktop wallpaper remains. It doesn't even show the shutdown screen (the one with the animated dots) where I could hit ESC and watch the shutdown console text. The system is brand-new and fully updated using Update Manager. How can I determine what is causing the freeze? Is there a log I can investigate? How can I fix this? I see no obvious cause of the freeze. The only USB attachment is a mouse/keyboard; I don't have any external storage attached; and I don't have any programs running (the machine freezes even when doing shutdown right from the login screen). What I've tried so far: Based on other questions (this, this, and this) that suggest some ACPI settings, I've tried sudo shutdown -h now to see whether the shutdown console text display offers any hints, but the system doesn't even get that far - it still freezes while the screen shown the desktop background image, without any toolbars. Only sudo shutdown --force works, but that's not a solution. Editing the grub menu to add acpi=off to the kernel didn't help. I guess there's not much point in trying the other (lesser) ACPI suggestions? Adding noapic to the grub entry had no discernible effect. Adding nolapic instead did something (I had removed the quiet option) - the system managed to continue further with the shutdown, right until the line Checking for running unattended-upgrades: which were the last characters on the screen. I've also checked the system BIOS, especially regarding power options, but didn't see anything out of the ordinary. Switching the BIOS standby setting from S3 to S1 didn't help. The standby setting can't be disabled, and there are no other ACPI-related settings AFAIK. BIOS reset didn't help. Not surprised; hadn't changed anything. I tried going to a virtual console (CtrlAltF1) as suggested by djeikyb and from there did a shutdown -h now and it froze there too, after this console output. I didn't try killing processes one at a time because I'm still too newbie to figure out how to do that. Booting with kernel 2.6.35.22 rather than 2.6.35.25 didn't help. Disabling the Nvidia drivers didn't help. Booting from Live CD (USB stick in fact) didn't help; it freezes the same way. Booting from Live CD, with acpi=off noapic nolapic didn't help either. Neither did just nolapic. So evidently this is not some custom setting in my install, but some sort of basic issue. MemTest competed in 1 hour without errors.

  • Evaluating Search Volume in Keyword Analysis For SEO

    Keyword analysis has to be one of the most important aspects of SEO. It does not matter how strong your link building is or if your on-page optimization is perfect, if your SEO efforts are not targeting a keyword with the right volume and low enough competition, you will only get a fraction of the traffic you could be getting.

  • RTS Game Style Application [closed]

    - by Daniel Wynand van Wyk
    My question may seem somewhat odd, but I hope that my specifications will clarify EXACTLY what it is that I am after. I need some help choosing the right tooling for a particular endeavour. My background is in desktop application development and large back-end systems. I have worked primarily on the Microsoft stack using C# and the .Net framework. My goal is to develop a 2D, RTS style, interactive office simulation. The simulation will model various office spaces, office equipment, employees and their interactions with one another. The idea is to abstract the concept of an office completely. Under the hood the application will do many things that are nothing like a game. This includes P2P networking, VPN tunnelling, streaming video, instant messaging, document collaboration, remote screen sharing, file-sharing, virus scanning, VOIP, document scanning, faxing, emailing, distributed computing, content management and much more! A somewhat similar thing has been attempted by IBM, where they created a virtual office in second life. If their attempt was a game, the game-play would be notably horrible, to say the least! The users/players will drive and control my application through the various objects modelled in the simulation. A single application capable of performing all of these various tasks would be a nightmare to navigate for even the most expert user. Using the concept of a game, I can easily separate functionality by assigning them to objects that relate 1-1 with their real world counter-parts. This can greatly simplify computing for novice users, with many added benefits in terms of visibility, transparency of process and centralized configuration. My hope is to make complex computing tasks accessible to all kinds of users and to greatly reduce the cognitive load associated with using the many different utilities and applications inside office settings. The complexity is therefore limited to the complexity of the space in which you find yourself. I want the application to target as many platforms as possible and run on computers that have no accelerated graphics capabilities. The simulation won't contain any of the fancy eye-candy you find in modern games, to the contrary, my "game" will purposefully be clean and simple. The closest thing I could imagine would be an old game like "Theme Hospital" or the first instalment of "The Sims". All the content will be pre-created and not user-generated like Second Life. New functionality will be added via a plugin system. Given my background and nature of my "game", I would like to spend most of my time writing code that does not have to do with the simulated office, as the "game" is really just a glorified application menu. I have done much reading about existing engines, frameworks and tools. I need the help of an experienced game developer who has tried and tested various products over the years who can guide me in the right direction given my very particular needs. I would appreciate any help I can get!

  • How can I change the default screen resolution?

    - by TheWackerly
    Here's the scoop: I have a crappy VisionQuest TV that I am currently using as a monitor on my computer running XBMCbuntu. It defaults to 1280x768 which the TV will not display correctly. It appears to be the correct size, but the screen is panned WAY to the left. The TV works fine on 1024x768 with the screen sitting in the right spot. Problem is, I have to change the resolution to 1024x768 every time I boot up. Any ideas?

  • Current activity logger

    - by user72605
    Very inexperienced coder here: Does anyone know of an app (for iOS or Mac) that asks for my current activity every hour or so? I see tons of apps that let you log your activities, but none that use popups/notifications to actively ask you. I found a script that looks promising (source), but I'm having trouble implementing it so that it repeats every hour: #!/bin/bash echo What are you doing right now? read -e what echo `date` - $what >> timelog.txt Thanks!

  • What is a good design model for my new class?

    - by user66662
    I am a beginning programmer who, after trying to manage over 2000 lines of procedural php code, now has discovered the value of OOP. I have read a few books to get me up to speed on the beginning theory, but would like some advice on practical application. So,for example, let's say there are two types of content objects - an ad and a calendar event. what my application does is scan different websites (a predefined list), and, when it finds an ad or an event, it extracts the data and saves it to a database. All of my objects will share a $title and $description. However, the Ad object will have a $price and the Event object will have $startDate. Should I have two separate classes, one for each object? Should I have a 'superclass' with the $title and $description with two other Ad and Event classes with their own properties? The latter is at least the direction I am on now. My second question about this design is how to handle the logic that extracts the data for $title, $description, $price, and $date. For each website in my predefined list, there is a specific regex that returns the desired value for each property. Currently, I have an extremely large switch statement in my constructor which determines what website I am own, sets the regex variables accordingly, and continues on. Not only that, but now I have to repeat the logic to determine what site I am on in the constructor of each class. This doesn't feel right. Should I create another class Algorithms and store the logic there for each site? Should the functions of to handle that logic be in this class? or specific to the classes whos properties they set? I want to take into account in my design two things: 1) I will add different content objects in the future that share $title and $description, but will have their own properties, so, I want to be able to easily grow these as needed. 2) I will add more websites constantly (each with their own algorithms for data extraction) so I would like to plan efficienty managing and working with these now. I thought about extending the Ad or Event class with 'websiteX' class and store its functions there. But, this didn't feel right either as now I have to manage 100s of little website specific class files. Note, I didn't know if this was the correct site or stackoverflow was the better choice. If so, let me know and I'll post there.

  • How to resize a LVM partition?

    - by iiddaannyy
    I want to shrink my second (lvm) partition, so I can create a new partition in the freespace. I am using Live-CD to do so, because I know I can't resize/move this partition while it is in use. When I opened GParted in Live-CD, I realized that I could not resize the partition, because when I right-click it, the option "resize/move" is disabled. I tried to unmount it, to "lazy" unmount it (umount -l /dev/sda2) but it didn't work. A screenshot from GParted:

  • Shut down/log out, me menu absent in panel

    - by Chethan S.
    I upgraded my Lucid installation to Maverick today via an alternate CD. Everything went fine but the shut down icon which provides the options to log out, suspend, hibernate etc. in the top right corner of the panel and the me menu which allows to set chat status are absent! I tried searching for suitable options in 'Add to Panel' but cannot find the exact solution - shut down provides option only to shut down, log out only to log out and so on.

  • Graphical disk surface check tool?

    - by sbergeron
    I need a program that can scan my hard drive for read and write errors so I can partition around them. I REALLY don't do well with numbers but if I can have something that shows an output like the graphical display on gparted that would be perfect. I know a lot of people would recommend replacing the disk but right now I can't as I NEED this laptop for school and can't wait for a hard drive to arrive (I have ordered one, yes, but I don't expect it to arrive for another couple weeks as I only figured out afterwards they still have to manufacture it)

  • Implications of Cisco open-sourcing H.264? [on hold]

    - by Suman
    Cisco has announced that it will license and open-source the H.264 video codec. As a result of this, Firefox will be embedding H.264 playback functionality in future versions of Firefox. What implications, if any, will this have for programmers building software and/or hardware dealing with video (and WebRTC in particular)? (And if programmers.SE isn't the right forum, please feel free to suggest a better option.)

  • Using NumPy arrays as 2D mathematical vectors?

    - by CorundumGames
    Right now I'm using lists as position, velocity, and acceleration vectors in my game. Is that a better option than using NumPy's arrays (not the standard library's) as vectors (with float data types)? I'm frequently adding vectors and changing their values directly, then placing the values in these vectors into a Pygame Rect. The vector is used for position (because Rects can't hold floats, so we can't go "between" pixels), and the Rect is used for rendering (because Pygame will only take in Rects for rendering positions).
