• Windows Randomly Stop Accepting Input from Bluetooth Keyboard

  - by dragonmantank

  I've got a laptop running Ubuntu 11.10 with the most recent updates and an Apple Wireless Keyboard that syncs via bluetooth. The Ubuntu box is also a Synergy server, using QuickSynergy to run Synergy. I'm using xmodmap to swap the option and command keys, but nothing else. Throughout the day, windows that are long running will just stop accepting input. For example, I leave gnome-terminal up and running almost 24 hours a day. If it sits for a while, it just stops accepting input. It doesn't matter if I'm ssh'd into another machine or sitting on a local tty session, it just stops accepting input. If I open a new tab or window, those work fine. The 'broken' tabs stay broken. I'm also running Turpial (a Twitter client) which will do that same thing. I tend to use the arrow keys to navigate, and it just stops accepting input. Closing it and reopening it causes it to work fine. I don't seem to have the problem in Chrome, but I tend to open up new tabs when I go somewhere instead of using existing tabs. I've updated all the packages, rebooted, and the only thing that seems to cure it is if I type on the built-in keyboard, the window will start to accept text from the bluetooth keyboard (until it stops again). I don't think the keyboard is disassociating from the laptop because it can happen while I'm using the keyboard, it seems more linked with windows that I sit for a long time. As an example, I'm typing in Chrome with the bluetooth keyboard but I have a terminal window that won't accept input.

• Decorator not calling the decorated instance - alternative design needed

  - by Daniel Hilgarth

  Assume I have a simple interface for translating text (sample code in C#): public interface ITranslationService { string GetTranslation(string key, CultureInfo targetLanguage); // some other methods... } A first simple implementation of this interface already exists and simply goes to the database for every method call. Assuming a UI that is being translated at start up this results in one database call per control. To improve this, I want to add the following behavior: As soon as a request for one language comes in, fetch all translations from this language and cache them. All translation requests are served from the cache. I thought about implementing this new behavior as a decorator, because all other methods of that interface implemented by the decorater would simple delegate to the decorated instance. However, the implementation of GetTranslation wouldn't use GetTranslation of the decorated instance at all to get all translations of a certain language. It would fire its own query against the database. This breaks the decorator pattern, because every functionality provided by the decorated instance is simply skipped. This becomes a real problem if there are other decorators involved. My understanding is that a Decorator should be additive. In this case however, the decorator is replacing the behavior of the decorated instance. I can't really think of a nice solution for this - how would you solve it? Everything is allowed, even a complete re-design of ITranslationService itself.

• A Brief Soul Session with Joss Stone

  - by Oracle OpenWorld Blog Team

   By Karen Shamban The Oracle OpenWorld Music Festival is thrilled to have Joss Stone as one of its featured artists.  Stone took a few moments from her busy tour and travel schedule to answer a few questions for this blog, so read on:  Q. What do you like best about performing in front of a live audience?A. I love to bring the music to the people! It's all fun and games in the studio, and I love it, but the time comes when the world needs to hear it and it's nice to see their faces when they are hearing new songs. Q. Do you prefer smaller, intimate venues or larger, louder ones?  Why?A. I like the smaller ones sometimes, but it really depends on who is in the audience. I prefer it regardless of size when the audience is with you from the start and they dance and let the music take them over - as it does me when I'm on stage. Q. What about your fans surprises you?A. Not a lot really, they have always been very very sweet and polite and giving and loving. It doesn't surprise me because that's what the effect of music is. For the most part they are beautiful people. Little-known fact: Not only is Stone an award-winning musician, she acted in an award-winning television series, Showtime's The Tudors.  Stone played Anne of Cleves, Henry VIII's fourth wife.  Not only did she keep her cool - she kept her head. More about the Oracle OpenWorld Music Festival. More about Joss Stone.

• Azure Search Preview

  - by Greg Low

  One of the things I’ve been keeping an eye on for quite a while now is the development of the Azure Search system. While it’s not a full replacement for the full-text indexing service in SQL Server on-premises as yet, it’s a really, really good start. Liam Cavanagh, Pablo Castro and the team have done a great job bringing this to the preview stage and I suspect it could be quite popular. I was very impressed by how they incorporated quite a bit of feedback I gave them early on, and I’m sure that others involved would have felt the same. There are two tiers at present. One is a free tier and has shared resources; the other is currently $125/month and has reserved resources. I would like to see another tier between these two, much the same way that Azure websites work. If you have any feedback on this, now would be a good time to make it known. In the meantime, given there is a free tier, there’s no excuse to not get out and try it. You’ll find details of it here: http://azure.microsoft.com/en-us/documentation/services/search/ I’ll be posting more info about this service, and showing examples of it during the upcoming months.

• Using the Java SE 8 Date Time API with JPA 2.1

  - by reza_rahman

  Most of you are hopefully aware of the new Date Time API included in Java SE 8. If you are not, you should check them out right now using the Java Tutorial Trail dedicated to the topic. It is a significantly leap forward in processing temporal data in Java. For those who already use Joda-Time the changes will look very familiar - very simplistically speaking the Java SE 8 feature is basically Joda-Time standardized. Quite naturally you will likely want to use the new Date Time APIs in your JPA domain model to better represent temporal data. The problem is that JPA 2.1 will not support the new API out of the box. So what are you to do? Fortunately you can make use of fairly simple JPA 2.1 Type Converters to use the Date Time API in your JPA domain classes. Steven Gertiser shows you how to do it in an extremely well written blog entry. Besides explaining the problem and the solution the entry is actually very good for getting a better understanding of JPA 2.1 Type Converters as well. I think such a set of converters may be a good fit for Apache DeltaSpike as a Java EE 7 extension? In case you are wondering about Java SE 8 support in the JPA specification itself, Nick Williams has already entered an excellent, well researched JIRA entry asking for such support in a future version of the JPA specification that's well worth looking at. Another possibility of course is for JPA providers to start supporting the Date Time API natively before anything is formalized in the specification. What do you think?

• Is there an excuse for excessively short variable names?

  - by KChaloux

  This has become a large frustration with the codebase I'm currently working in; many of our variable names are short and undescriptive. I'm the only developer left on the project, and there isn't documentation as to what most of them do, so I have to spend extra time tracking down what they represent. For example, I was reading over some code that updates the definition of an optical surface. The variables set at the start were as follows: double dR, dCV, dK, dDin, dDout, dRin, dRout dR = Convert.ToDouble(_tblAsphere.Rows[0].ItemArray.GetValue(1)); dCV = convert.ToDouble(_tblAsphere.Rows[1].ItemArray.GetValue(1)); ... and so on Maybe it's just me, but it told me essentially nothing about what they represented, which made understanding the code further down difficult. All I knew was that it was a variable parsed out specific row from a specific table, somewhere. After some searching, I found out what they meant: dR = radius dCV = curvature dK = conic constant dDin = inner aperture dDout = outer aperture dRin = inner radius dRout = outer radius I renamed them to essentially what I have up there. It lengthens some lines, but I feel like that's a fair trade off. This kind of naming scheme is used throughout a lot of the code however. I'm not sure if it's an artifact from developers who learned by working with older systems, or if there's a deeper reason behind it. Is there a good reason to name variables this way, or am I justified in updating them to more descriptive names as I come across them?

• Using Computer Management (MMC) with the Solaris CIFS Service (August 25, 2009)

  - by user12612012

  One of our goals for the Solaris CIFS Service is to provide seamless Windows interoperability: not just to deliver ubiquitous, multi-protocol file sharing, which is obviously a major part of this project, but to support Windows services at a fundamental level.  It's an ongoing mission and our latest update includes support for Windows remote management. Remote management is extremely important to Windows administrators and one of the mainstay tools is Computer Management. Computer Management is a Windows administration application, actually a collection of Microsoft Management Console (MMC) tools, that can be used to configure, monitor and manage local and remote services and resources.  The MMC is an extensible framework of registered components, known as snap-ins, which allows Computer Management to provide comprehensive management features for both the local system and remote systems on the network. Supported Computer Management features include: Share ManagementSupport for share management is relatively complete.  You can create, delete, list and configure shares.  It's not yet possible to change the maximum allowed or number of users properties but other properties, including the Share Permissions, can be managed via the MMC. Users, Groups and ConnectionsYou can view local SMB users and groups, monitor user connections and see the list of open files. If necessary, you can also disconnect users and/or close files. ServicesYou can view the SMF services running on an OpenSolaris system.  This is a read-only view - we don't support service management (the ability to start or stop) SMF services from Computer Management (yet). To ensure that only the appropriate users have access to administrative operations there are some access restrictions on these remote management features. Regular users can: List shares Only members of the Administrators or Power Users groups can: Manage shares List connections Only members of the Administrators group can: List open files and close files Disconnect users View SMF services View the EventLog Here's a screenshot when I was using Computer Management and Server Manager (another Windows remote management application) on Windows XP to view some open files on an OpenSolaris system to prepare a slide presentation on MMC support.

• How to really master ASP.NET MVC?

  - by user1620696

  Some years ago I've worked with web development just using PHP without focus on object orientation and so on. When I knew a little bit about it, and the benefits it brings, I've started moving to ASP.NET MVC. First, I've studied C# in the book Visual C# Step by Step. I've found it a good book for a beginner, and I could learn a lot of this new language with it. Now, when I've came to study ASP.NET MVC, I hadn't so much luck. I've studied on some books that explained MVC well and so on, but then started just saying: "do that, and now that, and then that", and I feel I couldn't really master ASP.NET MVC. I feel this, because when I was reading, I knew how to do the things the book taught, like implementing DI with Ninject and so on, but some time later, without looking at it for some time, I couldn't do it by myself. What I'm trying to say, is that usually I don't know where to start, how to do things in this framework and so on. How can I really master ASP.NET MVC? There is some book, some tutorial series, anything, that can really help with that? I'm pretty happy with the .NET framework, my problem isn't it, my only problem is working with the MVC framework, and applying the techniques from object orientation there. I don't know if this question is on-topic here, but I'm really just looking for some good references, to become better with this framework.

• New Feature! Automatic Categories for Geekswithblogs.net

  - by Jeff Julian

  One of the features we have been working on is a way to categorize posts without the need of all our bloggers getting on the same page with what categories we have and making them select the categories.  Johnny Kauffman, one of our team members at AJI Software, developed what we call the Sherlock Project over the past few months.  Sherlock is a category suggestion engine based on the content within the posts.  Now, after a post is published, Sherlock will investigate the content and come up with the suggested categories that content fits in.  This will now allow you to go to the specific topics you are interested in and see all the related posts. This is just the beginning, so many more opportunities will arise now that we have our content organized.  One of the first features I will be adding is RSS feeds for each category and sub category.  If you are into ALM, we will have a feed for that! I hope you enjoy these and the engine will continue to get better as we start testing the data.  I hope you are as excited about this as I am :D.  Technorati Tags: Geekswithblogs.net,Categories,Sherlock

• Develop for Desktop and mobile use?

  - by ran2

  I am in the very beginning of developing an app / desktop program. I want it to be cross-platform and possibly also as a tablet version (preferably Android Icecream sandwich). Note that I need to run it offline. I thought about the following approaches: ADOBE Air, since I do not need much performance. Plus I did some web programming in the past which might be of some use. Afaik it would run on OS X and Windows and should run on mobile OSes, too. Qt. Found some nice Qt based desktop recently and read it also works on android. Plus I like the SDK. HTML5 / JS. Again my web background should help me here. I wont need no sever side scripts, thus it should work without installing anything but a browser. How easy could this be converted into an Android app? There might be a plethora of other (better) ways to do it, but I haven't thought of them yet. Can you help out? How would you create such an application. Would it be better to do some pure desktop client and then create tablet versions? Would you rather start to create a website and worry later on how to turn into an app?

I have no idea about that so please tell what you guys suggest. thanks for every one's opinion in advance.

• I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

  - by Shin San

  I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

• Update Google Sitemap for Mobile

  - by dimo414

  I have a series of utilities to generate Google sitemaps for my whole site. These files are massive, and slow to build. We want to start telling Google these pages are mobile-crawl-able too, by adding them to mobile sitemaps, but the documentation is unclear if I need to specify physically different files for my mobile URLs than for my normal ones. If this is my current sitemap: <?xml version="1.0" encoding="UTF-8" ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>http://mobile.example.com/article100.html</loc> </url> </urlset> Can I simply change it to: <?xml version="1.0" encoding="UTF-8" ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:mobile="http://www.google.com/schemas/sitemap-mobile/1.0"> <url> <loc>http://mobile.example.com/article100.html</loc> <mobile:mobile/> </url> </urlset> Or do I need to create new files with the additional markup, alongside my existing files?

• Raspberry Pi Now Shipping with 512MB RAM; Still Only $35

  - by Jason Fitzpatrick

  Fans of the tiny Raspberry Pi will be pleased to hear the new version of their Model B board now ships with 512MB of RAM (up from the previous 256MB). The best part about the upgrade? The price point stays at $35 a board. From the official Raspberry Pi blog: One of the most common suggestions we’ve heard since launch is that we should produce a more expensive “Model C” version of Raspberry Pi with extra RAM. This would be useful for people who want to use the Pi as a general-purpose computer, with multiple large applications running concurrently, and would enable some interesting embedded use cases (particularly using Java) which are slightly too heavyweight to fit comfortably in 256MB. The downside of this suggestion for us is that we’re very attached to $35 as our highest price point. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard. If you have an outstanding order with either distributor, you will receive the upgraded device in place of the 256MB version you ordered. Units should start arriving in customers’ hands today, and we will be making a firmware upgrade available in the next couple of days to enable access to the additional memory. We’re excited to get our hands on a new board and try out Raspbmc with that extra RAM. HTG Explains: What is the Windows Page File and Should You Disable It?

• Searching for entity awareness in 3D space algorithm and data structure

  - by Khanser

  I'm trying to do some huge AI system just for the fun and I've come to this problem. How can I let the AI entities know about each other without getting the CPU to perform redundant and costly work? Every entity has a spatial awareness zone and it has to know what's inside when it has to decide what to do. First thoughts, for every entity test if the other entities are inside the first's reach. Ok, so it was the first try and yep, that is redundant and costly. We are working with real time AI over 10000+ entities so this is not a solution. Second try, calculate some grid over the awareness zone of every entity and test whether in this zones are entities (we are working with 3D entities with float x,y,z location coordinates) testing every point in the grid with the indexed-by-coordinate entities. Well, I don't like this because is also costly, but not as the first one. Third, create some multi linked lists over the x's and y's indexed positions of the entities so when we search for an interval between x,y and z,w positions (this interval defines the square over the spatial awareness zone) over the multi linked list, we won't have 'voids'. This has the problem of finding the nearest proximity value if there isn't one at the position where we start the search. I'm not convinced with any of the ideas so I'm searching for some enlightening. Do you people have any better ideas?

• Who is a CMS really for?

  - by Eirc man

  I have started lately discovering Content Management Systems, and I was wondering, who is really CMS for? What I mean by that: is it only for companies, small businesses or individuals, that pays a contractor to make a website that it's users can just upload content through a easy interface. Or is it used also by programmers, to build their own websites, projects? Would a Facebook, Tweeter, StackExhange ever started by using a CMS, a very powerful one for example. Would you as a programmer build your own "fancy" website on top of a CMS, for example like Typo3, or you would build it from scratch? P.S To be more clear is a summary: What I mean to begin with is, would I as a developer choose a CMS to develop a website that can be scaled with a big base of users, be stuck if I choose to start with a CMS system. What if I build a website using CMS, and the website explodes in popularity, and then I wanted to add much more functionality that I have planed, is it possible that the CMS will limit the growth, because it might have not been build for that kind of scale?

• dual monitors and unity - ati radeon cards

  - by michiel

  I have a vaio laptop with an ATI Radeon video card and an external screen. I used to run dual monitors on Ubuntu 10.10 fine, but recently decided to upgrade to 11.10 via 11.04 I don't think it's the video card or the fglrx driver. It seems to be unity. When I start up, the laptop screen is normal and the external screen is all white, although I can move my mouse over it. However, the cursor becomes the big X that used to be cursor of the first versions of Xwindows. I can right click on it, and it brings up the context menu for the desktop. And then, all of a sudden, it shows my desktop background. I can continue to move my mouse over the external screen, and now the cursor is normal (little white arrow). But I can't do anything any longer (not even the context menu as before), and trying to drag a window to it (which always worked on 10.10) doesn't work. I actually really like unity. It gives me the most our of my desktop, and uses all space available, which is great. But how can I get my second screen back? I tried unity 2D, but the result is the same. Edit: I think I stumbled on this bug: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/882143

• Screencast not producing files

  - by JohnS

  I'm using Gnome 3 on 12.04 and trying to create a screencast. I start the screencast using the Ctrl-Alt-Shift-R shortcut and the red light appears in the bottom right corner. I go about my business then press the key combination again when done. The problem is that the screencast file gets generated maybe 1 out of 10 times. Is there a log file I can look at to determine the issue? How about a settings file? UPDATE: I did some additional testing. What's happening is that the screencast does work but it appends the new video to the existing file. Even if the file is renamed or moved to trash. Emptying trash does not create a new file either. Not sure where the video gets recorded to then. The only reliable way I've found to have a new file created is to log out of the session and log back in. Is this expected behaviour? Is there a way to force screencast to create a new file every time Ctrl-Alt-Shift-R is pressed?

  This might be a question for ServerFault, and f it wasn't for the Plesk aspect I would ask it there to start with, so if it's better suited for over there let me know and I'll move it. I'm working on a dedicated server set up as a reseller account with Plesk to manage the domains and server configuration, and i need to add a directory to the local open_basedir configuration for a specific vhost. Given Plesk's normal methodology, I expected to be able to go to /var/www/vhost/{%DOMAINNAME%}/conf and modify vhost.conf and place a new value there, as I have successfully done with other configuration settings for this domain (turning safe_mode off, for instance). When I do so, however, the new setting doesn't take (per phpinfo();). If I edit httpd.conf (which the plesk configuration specifically says not to do in the notes at the top of httpd.conf) the setting takes. Is there something specific about the open_basdir setting that makes it not configurable in vhost.conf? How much trouble am I letting myself in for by editing the vhost-specific httpd.conf (I imagine is someone makes changes in the plesk web interface it might be overwritten, but what other risk is there)? Thanks!

• Algorithm for detecting windows in a room

  - by user2733436

  I am dealing with the following problem and i was looking to write a Pseudo-code for developing an algorithm that can be generic for such a problem. Here is what i have come up with thus far. STEP 1 In this step i try to get the robot where it maybe placed to the top left corner. Turn Left - If no window or Wall detected keep going forward 1 unit.. if window or wall detected -Turn right -- if no window or Wall detected keep going forward.. if window or wall detected then top left corner is reached. STEP 2 (We start counting windows after we get to this stage to avoid miscounting) I would like to declare a variable called turns as it will help me keep track if robot has gone around entire room. Turns = 4; Now we are facing north and placed on top left corner. while(turns0){ If window or wall detected (if window count++) Turn Right Turn--; While(detection!=wall || detection!=window){ move 1 unit forward Turn left (if window count++) Turn right } } I believe in doing so the robot will go around the entire room and count windows and it will stop once it has gone around the entire room as the turns get decremented. I don't feel this is the best solution and would appreciate suggestions on how i can improve my Pseudo-code. I am not looking for any code just a algorithm on solving such a problem and that is why i have not posted this in stack overflow. I apologize if my Pseudo-code is poorly written please make suggestions if i can improve that as i am new to this. Thanks.

• HP Pavilion 15 with AMD dual graphics - Ubuntu live environment not starting

  - by creepus

  I've had this laptop for about a day now and have decided to try Ubuntu on it and determine if I want to install it. I created a USB, it booted (Secure Boot was on, I tried with Secure Boot off to no effect), and then the problem occurred. The screen turned off for a second, turned back on to a black screen, shut off again and turned back on with a dialogue box telling me that the system had to use low-graphics mode. I clicked OK, selected low-graphics mode from the menu and clicked OK. The screen switched to the boot messages and did not go any further than this. Ctrl+Alt+DEL started rebooting the laptop though. I tried booting again, but this time I edited the boot options in GRUB to add nomodeset. This time, the laptop only booted to a black screen. Ctrl+Alt+F2 took me to a prompt, I tried startx from there, but X didn't start, complaining that it wanted kernel mode setting back. I can not seem to find any option to disable one graphics chip or the other in the UEFI setup menus. Laptop : HP Pavilion 15-E004AU. The CPU : AMD A6-4400M APU with Radeon(tm) HD Graphics The graphics chip : AMD Radeon HD 7520G + 8670M Dual Graphics. The Ubuntu version : 13.10, 64 bit. Thanks. EDIT: I tried 12.04.3 LTS, it managed to bring the desktop up. There are severe graphics glitches after about two minutes though.
