• Dropbox indicator icon dissapears right after login

  - by garvamel

  Even though Dropbox's app indicator dissapearing from the tray area seems like a recurrent enough problem, my issue is a litte different. When I login, I can see the app panel populating, and the dropbox icon does indeed appear (config'd as startup application), but after some other icons show up (bluetooth, battery, etc.) it's gone. It's still running though. I'm guessing it's having issues with staying pinned, and I don't know how to start addressing this problem. I have tried many if not all solutions provided here in the forums for the "icon missing" questions. So far: I've whitelisted everything regarding panel Uninstalled-reinstalled (with and without rebooting in between) Overwritten current installation Purged installation from terminal Installed from Software Center and from .deb file batch deleted every "dropbox" ocurrences from terminal (files and folders) and reinstalled Ran sudo apt-get install libappindicator1, it installed, but didn't solve anything I'm on Ubuntu 12.04 LTS - 64 bits. Any insight would me much appreciated!

• Toshiba satellite L500 no Wifi anymore!

  - by Benjamin Piller

  I have a Toshiba Satellite L500 with Ubuntu 12.04 and its wifi suddenly stopped working!! I've never seen like that before.. I tried also using external USB wifis but no success. I am not able to turn it on with the function keys nor using rfkill commands and similar WLAN manipulator Commands in the terminal! It was working before for at least 4-5 months!! The computer says it's turned off by hardware. I checked it and the Driver is fine. So why can i not use any Wifi on my computer?? Why it is suddenly disabled? I checked the BIOS too there is enabled the WLAN. I spent 10 hours for searching for solutions but i am out of ideas!!! Please Help!

• What are the common character animation techniques used in tile based hack&slash games?

  - by Gorky

  I wonder what kind of animation techniques are used for creature and character animation in modern hack&slash type tile based games? Keyframing for different actions may be one option. Skeletal framing may be another. But how about the physics? Or do they use a totally hybrid system of inverse kinematics supported with a skeleton,physics and mixed with interpolated keyframing for more realistic animations? If so, how and for what reasons? I can think of many different solutions for the issues below but I wonder what's used and best suited for issues like: Walking or moving on an uneven terrain Combat interaction, combat physics and collisions Attaching rigid items to character and their iteractions ih physics world Soft body dynamics like hair, vegetation, clothes and fabric in line with animations and iteractions.

• In 12.04 LTS, I get "No DBus" errors when running things as root

  - by Seann

  While attempting to run gEdit as root from a terminal window (was trying to do some tweaking on my HOSTS and FSTAB files), I get a message saying "No DBus connection available" and get booted back to the prompt. However, I can run Nautilus from the prompt like that (still get the error, but it runs all the same), and use WINE and NOTEPAD, and was able to make my changes. I thought maybe DBUS was missing, but APT says it's installed and gEdit runs fine when not elevated. Granted, I don't have to elevate often, but on the off-chance I do, (like adding or changing SMB/CIFS mountpoints in FSTAB), I would like to use gEdit, not NOTEPAD from WINE, and not in a terminal window with VI (well VIM). Ideas? Solutions?

• Associative array challenges, or examples?

  - by Aerovistae

  I understand well when and how to use an associative array, but I'm trying to teach a friend to program and I'm having some trouble with this particular concept. I need a good set of problems whose solutions are best implemented through the use of maps/hashes/associative arrays/dictionaries. I googled all over and couldn't find any. I was hoping someone might know of some, or perhaps get a community wiki sort of answer. That way I can say, here's our problem, and here's how we could effectively solve it through the use of an associative array... It's one of those cases where when I'm programming and I run into a situation that calls for a dictionary, I recognize it, but I can't seem to make up any such situations to use for a demonstration.

• Scheme of work contract

  - by Tommy

  I'm in the process of setting up a (one man) company and got to a item on my list "contracts and insurance". I will primary be offering custom software development but may also offer some "open source solutions", install, configure / manage e.t.c. I'm not sure how to approach a contract with a potential customer. I want to be flexible and offer the customer rights over the product (when not using open source of course) but I obviously want / need to be able to reuse code, already written and any future work. Is this possible or is it just something that people do but strictly they shouldn't? Is there a standard freelancing / contacting developer agreement? Going to a lawyer I'm sure is an answer but a very expensive one! If not do you end up with a fresh contract with each job / client and lots of trips to solicitors?

• How to Use KeePass In Your Browser, Across Your Computers, and On Your Phone

  - by Chris Hoffman

  If you’re using a password manager and it’s not the cloud-based LastPass, it’s probably KeePass. KeePass is a completely open-source password manager that stores all your sensitive data locally. However, this means that it isn’t quite as well-integrated as other solutions. Want LastPass-style browser integration, the ability to synchronize your passwords and have them everywhere, and an app to access your passwords on your phone? You’ll have to string together your own system.

• Ubuntu 12.04 shut down freezes

  - by sam

  I am using Ubuntu 12.04 for last one month without any problem. It was upgraded from Ubuntu 10.10. Recently I needed to replace my hard disk. After replacement I installed Windows 7 and Ubuntu 12.04 on the system. For some days it went ok, but now shutting down from Ubuntu is causing problems. It freezes on the text screen saying acpid=exiting checking for running unattended upgrades. After that I waited for a long time, but it didn't go off and I had to hit ctrl+alt+del to restart the system and booting from Windows and then shutting down from there. This happens every time I shut down my system from Ubuntu. I have seen many posts regarding the same kind of issues but none of the solutions reported there helped me out.

• Windows 8 and Ubuntu 12.10 dual boot

  - by Marty

  I have been having a tough time getting a new computer (Lenovo h430) that came with windows 8 to dual boot with ubuntu linux. I can get ubuntu to install from a usb drive and can use the live system (ubuntu 12.10) but dual booting has not worked. I have cruised the internet and tried a number of solutions such as easybcd 2.2 and boot repair under linux. I have also gone into the setup screen to try and fix it but the lenovo acromyms in the setup are not illuminating for me. Does anyone know of a clear set of instructions for installing ubuntu on a machine delivered with windows 8 ?

• One-way platforms in UDK

  - by Jordaan Mylonas

  I'm looking to make a multi-player platforming game using UDK. I'm currently doing feasibility research, to make sure I will reasonably be able to do all of the technical things I want to do. The first major hurdle I've come across without being able to find as answer, are one-way platforms. That is to say, platforms through which a player can jump up, but not fall through (unless they choose to). These are commonly seen in games like Mario, Kirby and Smash Bros. Does anyone know how such a system would work within UDK? I can think of solutions that might work for single-player, but not multi.

• BeanInfo Editor in NetBeans Rocks

  - by Geertjan

  Impressed by a cool feature I didn't know about. If you have some JavaBean, like my Event class below, you can right-click it and choose "BeanInfo Editor": Now, as you can see above, I don't have a BeanInfo class. So I am now asked whether the IDE should create one for me. So I say OK and then I have a new BeanInfo class, generated from my Event class, as well as a multiview editor for visually editing the BeanInfo class: Thanks Eric and Nicklas from Artificial Solutions in Stockholm for pointing this out to me today. It comes in very handy in NetBeans Platform applications when you're working with a BeanNode and want to customize the display of your properties.

• How many hours can you be really productive per day? How?

  - by fzwo

  I find that I'm having a great deal of trouble staying alert 8 hours per day. I've heard of people who've negotiated work contracts of just 4 hours/day, arguing that they won't be able to do much more in eight hours. I am often overwhelmed with drowsiness, boredom, distraction. Some days, I seem to blaze through eight hours in a furious explosion of productivity; other days, I hardly get anything done at all. Most days, it's somewhere in between, and I feel bad for wasting a lot of time because I can't muster the concentration to be my best throughout much of the day. I'd like to hear your experiences (tell me I'm not alone!), and, if found, your solutions to this dilemma. Are you productive 8 hours/day almost every day? How?

• Lag compensation of projectile shooting game

  - by Denis Ermolin

  I'm thinking about an algorithm for firing projectiles with lag compensation. Now I did find only one descent solution: Player hits fire button. Client sends input "fire". Client waits for server response. Server generates bullet then sends response to client. Client recieves response and finally fires projectile. Is this solution only "trueway"? I find it the only one that can be fair to all of the clients. Valve in this case, doesn't compensate lag from rocket shots. I am feeling that I will not compensate it, too. I think that with today's bandwidth I can close my eyes on this problem, because I don't see any solutions with fair logic. What do you think?

• Traditional POS is Dead

  - by David Dorf

  Traditional POS is dead -- I've heard that one before. Here's an excerpt from Joe Skorupa's blog over at RIS where he relayed ten trends that were presented at NRF. 7. Mobile POS signals death of traditional POS. Shoppers don't love self-checkout, but they prefer it to long queues or dealing with associates. Fixed POS is expensive and bulky. Mobile POS frees floor space for other purposes and converts associates from being cashiers to being sales assistants that provide new levels of customer service and incremental basket sales. In addition to unplugging the POS, new alternatives are starting to take hold - thin client, POS as a service, and replacing POS software with e-commerce platforms. I'll grant that in some situations for some retailers there might be an opportunity to to ditch the traditional POS, but for the majority of retailers that's just not practical. Take it from a guy that had to wake up at 3am after every Thanksgiving to monitor POS systems across the US on Black Friday. If a retailer's website goes down on Black Friday, they will take a significant hit. If a retailer's chain-wide POS system goes down on Black Friday, that retailer will cease to exist. Mobile POS works great for Apple because the majority of purchases are one or two big-ticket items that don't involve cash. There's still a traditional POS in every store to fall back on (its just hidden). Try this at home: Choose your favorite e-commerce site and add an item to the cart while timing how long it takes. Now multiply that by 15 to represent the 15 items you might buy at store like Target. The user interface isn't optimized for bulk purchases, and that's how it should be. The webstore and POS are designed for different purposes. Self-checkout is a great addition to POS and so is mobile checkout. But they add capabilities to POS, not replace it. Centralized architectures, even those based in the cloud, are quite viable as long as there's resiliency in the registers. You cannot assume perfect access to the network, so a POS must always be able to sell regardless of connectivity. Clearly the different selling channels should be sharing common functionality. Things like calculating tax, accepting coupons, and processing electronic payments can be shared, usually through a service-oriented architecture. This lowers costs and providers greater consistency, both of which help retailers. On paper these technologies look really good and we should continue to push boundaries, but I'm not ready to call the patient dead just yet.

• Approaching SICP in Clojure instead of Scheme

  - by ironicaldiction

  I am a third year bachelor student in a software engineering program, and I brought up the idea of reading SICP to an adviser to gain a deeper and more fundamental understanding of the principles behind all this software we engineer. He suggested not to learn Scheme to complete the book (because it's not as common as modern dialects of Lisp) but to do the exercises in Clojure instead. It's an already difficult book, if I do attempt the book's exercises in the more modern Clojure, how would that work? For example, I can't find any real solutions, the syntax they teach for Scheme is different, etc.
