  • Screen dims on opening certain applications on Macbook

    - by yayu
    I have ubuntu 11.10 installed on an old 2008 macbook. There is an issue of screen dimming that I didnt find anywhere else on the forums. The issue is that the screen is dimmed when I open certain applications (Firefox, Software Center) and this cannot be readjusted by the physical brightness buttons on the keyboard. I tried a bunch of things on the barely barely visible screen, and had no choice but to restart. This has happened everytime. Does anyone know how to solve this?

  • Will the new Unity desktop be programmed in Qt?

    - by Brian Fleeger
    Will the desktop version of Unity, scheduled to appear in 11.04, be programmed using Qt? I ask this in relation to Matt Zimmerman's blog posting of several days ago, where he intimated that Qt was the more pragmatic choice for an SDK to get coders more involved. As a corollary, it would make sense if the whole desktop were in Qt, which would also make it possible to do a lot more beautiful effects, and make a more visually engrossing desktop experience. In any event, please elaborate on the future role of Qt in the Ubuntu desktop.

I have been struggling through google but couldn't find anything useful. All I could get was this link but it doesn't really solve my problem. Any help will be really helpful for me.

  • How to deal with tautology in comments?

    - by Tamás Szelei
    Sometimes I find myself in situations when the part of code that I am writing is (or seems to be) so self-evident that its name would be basically repeated as a comment: class Example { /// <summary> /// The location of the update. /// </summary> public Uri UpdateLocation { get; set; }; } (C# example, but please refer to the question as language-agnostic). A comment like that is useless; what am I doing wrong? Is it the choice of the name that is wrong? How could I comment parts like this better? Should I just skip the comment for things like this?

  • TechEd North America 2012–Day 2 #msTechEd #teched

    - by Marco Russo (SQLBI)
    This is the second day at TechEd North America 2012 and yesterday I had many conversations about PowerPivot and SSAS Tabular. In the evening the book signing at O’Reilley booth has been a big success! I’m writing this post from the speaker’s room. It’s not crowded this morning because the keynote is going on and there are no people also in the hall, everyone is in the keynote room. Today will be a very busy day: I’ll be staffing at Technical Learning Center from 12:30pm to 3:30pm so this is a first chance for joining the conversation about Tabular and DAX. But there is another choice this evening at Community Night starting at 6:30pm until 9:00pm. Join us at this Ask the Expert event! And, well, don’t miss the Many-to-Many Relationships in BISM Tabular from Alberto this afternoon at 5:00 pm in room S330E. Look at my yesterday’s post if you want to look at our full schedule for the week. Enjoy TechEd!

  • Transferring local site to shared hosting

    - by Pete
    I'm looking to setup a simple online text processing tool similar to the Clang demo. The processing program itself is a C++ program which I can modify to provide the desired output I need. Since I use Linux+Perl daily and have used Apache in the past, I'd like to get this working locally first. My two questions are: Is it possible to do this with only Apache and Perl? I've looked into frameworks for doing this and quickly ran into The Paradox Of Choice. Will I be able to easily transfer a working local site to a shared hosting service? I want to administer as little as possible. My understanding is since this needs to run a C++ program that CGI is a requirement and thus I need to administer the httpd server. Hopefully this doesn't mean a VPS. Thanks

  • Optimal Database design regarding functionality of letting user share posts by other users

    - by codecool
    I want to implement functionality which let user share posts by other users similar to what Facebook and Google+ share button and twitter retweet. There are 2 choices: 1) I create duplicate copy of the post and have a column which keeps track of the original post id and makes clear this is a shared post. 2) I have a separate table shared post where I save the post id which is a foreign key to post id in post table. Talking in terms of programming basically I keep pointer to the original post in a separate table and when need to get post posted by user and also shared ones I do a left join on post and shared post table Post(post_id(PK), post_content, posted_by) SharedPost(post_id(FK to Post.post_id), sharing_user, sharedfrom(in case someone shares from non owners profile)) I am in favour of second choice but wanted to know the advice of experts out there? One thing more posts on my webapp will be more on the lines of facebook size not tweet size.

  • How would you code an AI engine to allow communication in any programming language?

    - by Tokyo Dan
    I developed a two-player iPhone board game. Computer players (AI) can either be local (in the game code) or remote running on a server. In the 2nd case, both client and server code are coded in Lua. On the server the actual AI code is separate from the TCP socket code and coroutine code (which spawns a separate instance of AI for each connecting client). I want to be able to further isolate the AI code so that that part can be a module coded by anyone in their language of choice. How can I do this? What tecniques/technology would enable communication between the Lua TCP socket/coroutine code and the AI module?

  • Opinion of OSCON?

    - by 16bytes
    This year I have the opportunity to travel to the conference of my choice and thus far have been looking at OSCON. For those who have attended, what is your opinion of the conference? Any tips/tricks? Any tips to effectively plan what to see/attend? Any suggestions for lesser known conferences? As a working programmer, my interest is pretty general; I want to learn more about up-and-coming tech that I may have a chance to use and/or use more effectively.

  • designing classes with similar goal but widely different decisional core

    - by Stefano Borini
    I am puzzled on how to model this situation. Suppose you have an algorithm operating in a loop. At every loop, a procedure P must take place, whose role is to modify an input data I into an output data O, such that O = P(I). In reality, there are different flavors of P, say P1, P2, P3 and so on. The choice of which P to run is user dependent, but all P have the same finality, produce O from I. This called well for a base class PBase with a method PBase::apply, with specific reimplementations of P1::apply(I), P2::apply(I), and P3::apply(I). The actual P class gets instantiated in a factory method, and the loop stays simple. Now, I have a case of P4 which follows the same principle, but this time needs additional data from the loop (such as the current iteration, and the average value of O during the previous iterations). How would you redesign for this case?

  • Is there a good design pattern for this messaging class?

    - by salonMonsters
    Is there a good design pattern for this? I want to create a messaging class. The class will be passed: the type of message (eg. signup, signup confirmation, password reminder etc) the client's id The class needs to then look up the client's messaging preferences in the db (whether they want communication by email, sms or both) Then depending on the client's preference it will format the message for the medium (short version for sms, long form for email) and send it through our mail or sms provider's API. Because the fact that we want to be able to change out email and sms providers if need be I wondered if the Command Pattern would be a good choice.

  • manage 2 wireless device

    - by yi.tang.uni
    I erased Windows 7 and installed Ubuntu 12.04 on my Dell Latitude E4200. I an very happy with my choice but with little pity. I cannot use the wireless service in my university as the build-in device works unstable. I bought a USB wireless device, which solve the problem. However, the build-in device keep to sent me message about unable to connect, which waste laptop's cup & battery. The phsical bottom to turn off wireless affect both devices. So the question is: "How can I manually shut down wireless device?" There is another interest comes to my mind: "Does 2 wireless improve the overall internet usage if I run a high-internet-consuming program like BT ?" Thank for your time and energy.

  • 6 Start Menu Replacements for Windows 8

    - by Chris Hoffman
    Want a Start menu on your Windows 8 desktop? While Microsoft no longer includes the Start button, opting instead for a click in a hidden corner and a new Start screen, there are quite a few Start menu replacements you can choose from. You can try living without the Start button and customizing your Start screen – it’s very possible to get by without the Start button and some people seem to prefer the new interface – but you have a choice. Many of these tools also allow you to boot directly to the desktop and hide the charms and app switcher that appear when you move your cursor to the corners of the screen, giving you a more traditional desktop experience. What Is the Purpose of the “Do Not Cover This Hole” Hole on Hard Drives? How To Log Into The Desktop, Add a Start Menu, and Disable Hot Corners in Windows 8 HTG Explains: Why You Shouldn’t Use a Task Killer On Android

  • Windows 8 Consumer Preview and SkyDrive

    - by John Paul Cook
    SkyDrive integrates very nicely with Windows 8. More on that later. First, let’s discuss using Windows 8 x64 on VirtualBox. Since I wanted to test with x64 and didn’t have a Hyper-V server available, I used VirtualBox. The latest version of VirtualBox does list Windows 8 as a guest operating system choice. The first time I attempted the installation, I chose the experimental Direct3D graphics support. That didn’t work well. After what seemed like FOREVER looking at a completely black screen, I decided...(read more)

  • Few questions about Thunderbird in Ubuntu 11.10

    - by Darwell
    I am happy with Ubuntu choice to replace Evolution with Thunderbird. However, I am having some issues with it. 1. What do you use to make Thunderbird minimize (and disappear from the launcher) when closing it? It should still be running (and give me notifications of new emails) but do not bother me on Launcher or in the list of windows, because I need free space. I tried using FireTray extension, it works quite okay, but it's buggy - sometimes there are two instances of Thunderbird open when using it and also, Thunderbird's global menu disappears after some time of using the extension. 2. Is there a plan to integrate Thunderbird's calendars into Date indicator in Ubuntu? I'd like to see my events when I have clicked on the time. Thanks.

  • Developing a DVR software using a hardware KIT

    - by Leron
    I'm currently thinking about a project for my masters degree graduation. I start researching for options to make my own video streaming software based on a premade hardware kit having not much knowledge about what I'll exactly need that will match my needs. My search led me to the DVR (Digital Video Recorder) cards which seems to be the closest to what I need, but still I can't find out a few basic things so I decide to ask for them here. Currently I haven't find a lot of manufacturers that offers such kits so where I can look and have some options to choose from? There are a lot of DVR products on the market but they already have a software written for them and even if I buy one they just don't give any documentation or sdk's so buying such is not an option I need a DVR card made exactly for software programers and not end users. Are there a preferred manufacturers that provide such kind of devices with good and developer-friendly documentation? Also - I prefer to do all this with Java, is this an option (I think I will make it with .NET too but really prefer Java as a language of choice)

  • How to use driver for printer?

    - by jamie
    I've been trying to get my Lexmark x1290 to work on Ubuntu 12.04. According to this post, the z600 driver should work to print, so I downloaded the z600 driver from here and installed it through the Ubuntu Software Center. I plugged in my printer and went to the "Printer" section under System Settings... and followed the wizard to install it. It showed up as "1200-series" but never gave me a choice to choose the driver and when I try to print to it, it pops up a message that it is printing and then that it is done printing, but it is definitely not printing anything. What am I doing wrong here?

  • Easy Server-Side Language

    - by Nizar
    Most of programming languages (Server-side languages for web development) needs a learning curve and requires some time to learn. However, I'm sure there is a difference between them. So, for example you can master the 'X' language in less time than the 'Y' language. I'm a beginner in web development, meaning that I just know HTML and CSS and now want to choose the right tool for building dynamic sites. What I'm looking for is a language that is easy to master in less time than other languages. So, is there a language that can suit my needs? If so, please let me know about what should I learn in it? (for example, which frameworks?, libraries?, IDEs?, databases?, etc). In the end, I don't want to regret my choice of the language and want to learn solid basics in it and in programming in general.

  • What is the best way to implement paginated text editing in Python?

    - by W.F
    I'm trying to build a formatted text editor in python. I need the editor to be paginated on edit mode. Same as in all popular word processors - when the user is editing the document what he/she sees is a representation of the actual, physical, page. I've tried looking into PySide but I can't find any ready solution to this, nor I can work out a way to do it myself. I am totally open to new technologies, so if you think Python is not the right choice here I would love to hear about new stuff (especially when I'm this new to UI coding). It only needs to be cross-platform and let me do rapid development (hence me looking for an out-of-the-box solution to this). Please suggest the best way to implement this. Please also note that I am looking for either a ready solution or an advice on how to tackle this. Thank you very much !

  • How customers view and interact with a company

    The Harvard Business Review article written by Rayport and Jaworski is aptly titled “Best Face Forward” because it sheds light on how customers view and interact with a company. In the past most business interaction between customers was performed in a face to face meeting where one party would present an item for sale and then the other would decide whether to purchase the item. In addition, if there was a problem with a purchased item then they would bring the item back to the person who sold the item for resolution. One of my earliest examples of witnessing this was when I was around 6 or 7 years old and I was allowed to spend the summer in Tennessee with my Grandparents. My Grandfather had just written a book about the local history of his town and was selling them to his friends and local bookstores. I still remember he offered to pay me a small commission for every book I helped him sell because I was carrying the books around for him. Every sale he made was face to face with his customers which allowed him to share his excitement for the book with everyone. In today’s modern world there is less and less human interaction as the use of computers and other technologies allow us to communicate within seconds even though both parties may be across the globe or just next door. That being said, customers view a company through multiple access points called faces that represent the ability to interact without actually seeing a human face. As a software engineer this is a good and a bad thing because direct human interaction and technology based interaction have both good and bad attributes based on the customer. How organizations coordinate business and IT functions, to provide quality service varies based on each individual business and the goals and directives put in place by its management. According to Rayport and Jaworski, the type of interaction used through a particular access point may lend itself to be people-dominate, machine-dominate, or a combination of both. The method by which a company communicates information through an access point is a strategic choice that relates costs and customer outcomes. To simplify this, the choice is based on what can give the customer the best experience interacting with the company when the cost of the interaction is also a factor. I personally see examples of this every day at work. The company website is machine-dominate with people updating and maintaining information, our groups department is people dominate because most of the customer interaction is done at the customers location and is backed up by machine based data sources, and our sales/member service department is a hybrid because employees work in tandem with machines in order for them to assist customers with signing up or any other issue they may have. The positive and negative aspects of human and machine interfaces are a key aspect in deciding which interface to use when allowing customers to access a company or a combination of the two. Rayport and Jaworski also used MIT professor Erik Brynjolfsson preliminary catalog of human and machine strengths. He stated that humans outperform machines in judgment, pattern recognition, exception processing, insight, and creativity. I have found this to be true based on the example of how sales and member service reps at my company handle a multitude of questions and various situations with a lot of unknown variables. A machine interface could never effectively be able to handle these scenarios because there are too many variables to consider and would not have the built-in logic to process each customer’s claims and needs. In addition, he also stated that machines outperform humans in collecting, storing, transmitting and routine processing. An example of this would be my employer’s website. Customers can simply go online and purchase a product without even talking to a sales or member services representative. The information is then stored in a database so that the customer can always go back and review there order, and access their selected services. A human, no matter how smart they are would never be able to keep track of hundreds of thousands of customers let alone know what they purchased or how much they paid. In today’s technology driven economy every company must offer their customers multiple methods of accessibly in order to survive. The more of an opportunity a company has to create a positive experience for their customers, in my opinion, they more likely the customer will return to that company again. I have noticed this with my personal shopping habits and experiences. References Rayport, J., & Jaworski, B. (2004). Best Face Forward. Harvard Business Review, 82(12), 47-58.
