• Ubuntu 9.10 + LXDE Error unmet dependencies

  - by skg

  I am working on Ubuntu 9.10 + LXDE as my current project. I am finding it difficult to install any new packages on this OS. For example, I need to install OpenCv package for qt webcam application, but every time it gives unmet dependencies error.And when i try to install dependencies it again show some more dependencies and so on and forms a circular loops. for example: sudo apt-get install libcv-dev .. .... The following packages have unmet dependencies: libcv-dev: Depends: libhighgui-dev (=1.0.0-6.2ubuntu1) but it is not going to installed. E: Broken packages Then I try to install libhighgui-dev as follow: sudo appt-get install libhighgui-dev .. ... The following packages have unmet dependencies: libhighgui-dev: Depends: libgtk2.0-dev but it is not going to installed E: Broken packages And this goes on never ending. Please suggest me something, as i have googled a lot and did not found any help. It may be , i m missing some primary packages to be installed.But how to find it? Any suggestion/help/link will be really appreciated. Thanks in Advance.

• Can I change a MySQL table back and forth between InnoDB and MyISAM without any problems?

  - by Daniel Magliola

  I have a site with a decently big database, 3Gb in size, a couple of tables with a dozen million records. It's currently 100% on MyISAM, and I have the feeling that the server is going slower than it should because of too much locking, so I'd like to try going to InnoDB and see if that makes things better. However, I need to do that directly in production, because obviously without load this doesn't make any difference. However, I'm a bit worried about this, because InnoDB actually has potential to be slower, so the question is: If I convert all tables to InnoDB and it turns out i'm worse off than before, can I go back to MyISAM without losing anything? Can you think of any problems I might encounter? (For example, I know that InnoDB stores all data in ONE big file that only gets bigger, can this be a problem?) Thank you very much Daniel

• Loadbalancing Questions

  - by Van Holtz

  I have been learning networking for about 4 months. Wrote a single standalone Multiplayer server and succeeded with authoritative approach. Now I want to extend it by splitting the single server into clusters to allow even more players to log in to avoid latency issues. Now I have protyped the Loadbalancing server and its running pretty good so far. This is my architecture, I have a master server which acts as a proxy, every sub servers(chat, login, game) connect to the master server as well as all the clients. when a client connects, Client Request: Send Request - MS(Master) - Decides which SS(SubServer) to forward to - Forwards Request to SS - SS - Analyze Message - Send Response to MS - Decides which Client to forward to - Forwards Response to Client Well, it looks like its going through lots of stages. it takes double the time to process the message than a single server approach. i feel like my model isnt the best or i may be wrong. is there any better model or the one they use in professional games? I still want a Master-SubServer approach. I just want to clarify that I'm going in the right direction before writing all my codes. Thanks for any answer :)

• Server 2012 R2 DNS Conditional forwarding not working reliably, possible caching issue?

  - by Matt

  I have a bit of a home lab setup with a domain controller that is acting as the DNS server for my network. For everything, it's working fine and forwards external DNS requests to my ISP. The household recently wanted to get Netflix going and it seemed a DNS option was better than a VPN to get around the region locking, so I signed up for unblock-us.com Since I have a Windows DNS server I thought I'd be clever and make use of conditional forwarders and added the Netflix domain to the list. Initially this worked well and all devices on the network could now access Netflix, however after about an hour going to the Netflix site would result in a page cannot be found. Doing an nslookup of Netflix.com from my PC resulted in it not returning any IP addresses. As a test, I deleted the Netflix domain from the DNS servers cache and things started working again - devices could get to the site again however the same thing happens again after around half an hour to an hour. Have I missed something here that's causing it to stop working?

• Looking for a small, light scene graph style abstraction lib for shader based OpenGL

  - by Pris

  I'm looking for a 'lean and mean' c/c++ scene graph library for OpenGL that doesn't use any deprecated functionality. It should be cross platform (strictly speaking I just dev on Linux so no love lost if it doesn't work on Windows), and it should be possible to deploy to mobile targets (ie OpenGLES2, and no crazy mandatory dependencies that wouldn't port well to modern mobile frameworks like iOS, Android, etc), with a license that's compatible with closed source software (LGPL or more liberal). Specific nice-to-haves would be: Cameras and Viewers (trackball, fly-by, etc) Object transform hierarchies (if B is a child of A, and you move A, B has the same transform applied to it) Simple animation Scene optimization (frustum culling, use VBOs, minimize state changes, etc) Text I've played around with OpenSceneGraph a lot and it's pretty amazing for fixed function pipeline stuff, but I've had a few of problems using it with the programmable pipeline and after going through their mailing list, it seems several people have had similar issues (going back years). Kitware's VES looks neat (http://www.vtk.org/Wiki/VES), but VES + VTK is pretty heavy. VTK is also typically for analyzing scientific data and I've read that it's not that appropriate for a general use case (not that great at rendering a lot of objects on scene,etc) I'm currently looking at VisualizationLibrary (http://www.visualizationlibrary.org/documentation/pag_gallery.html) which looks like it offers some of the functionality I'd like, but it doesn't explicitly support mobile targets. Other solutions like Ogre, Horde3D, Irrlicht, etc tend to be full on game engines and that's not really what I'm looking for. I'd like some suggestions for other libraries that I may have missed... please note I'm not willing to roll my own solution from scratch.

• Why The Athene Group Chose Fusion CRM

  - by Tony Berk

  A guest post by Vikas Bhambri, Managing Partner, The Athene Group This year, The Athene Group (www.theathenegroup.com) celebrated our tenth anniversary. The company has accomplished a lot in ten years overcoming a number of hurdles and challenges to have grown organically to a 150+ person global company with offices in the US, UK, and India and customers in the US, Canada, and Europe. Now more than ever with the current global landscape from an economic and competitive standpoint it was vital that we make some changes to remain successful for the next ten years. There were two key initiatives that we discussed internally that would enable us to successfully accomplish this – collaboration and the concept of “insight to action”. With our existing Oracle CRM On Demand platform we had components of this but not the full depth and breadth that we were looking for. When we started to discuss Fusion CRM we immediately saw several next generation tools that would embrace these two objectives. For a consulting and development organization the collaboration required between business development and consulting delivery is as important as the collaboration required during the projects between the project delivery and account management teams. The Activity Streams functionality in Fusion CRM immediately addressed the communication of key discussion topics and exchanges around our clients. Of course when we saw the Oracle Social Network (which is part of our Fusion CRM roadmap) we were blown away. The combination OSN and our CRM is going to make us more effective as we discuss and work cohesively on client engagements – ensuring mutual success for both Athene and our clients. When we looked at “insight to action” we saw that we had a great platform when folks were at their desks, unfortunately a lot of our business development and consulting folks are on the road. The Fusion Mobile Sales and Fusion Outlook Desktop provide information to our teams when they are on the go. So that they can provide real-time information and react to real-time information provided by their peers. We are in the early stages of our transformative experience with Fusion CRM but we believe the platform along with our people and processes are going to help us achieve our goals in the future.

• PPF Savings Interest Rate Increased To 8.6% From 8% [India]

  - by Gopinath

  Here is some good news to small Indian investors who save money in Public Provident Fund(PPF) accounts operated in Post Offices and few nationalized banks – returns of your PPF savings are going to increase. Indian government has decided to increase the rate of interest paid to customers from 8% to 8.6%. To put it in numbers, if you have a 2,00,000 of savings in PPF account they are going give returns of 17,200/- per annum compared to 16,000/- returns at 8%. Also the the maximum cap on the investments in to PPF account per annum is increased to 1,00,000 from 70,000/-. PPF is one of the safest debt investments that gives very decent returns, but if you are a salaried employee with PF account then consider investing in Voluntary PF(VPF) instead of PPF as VPF returns are higher than PPF.

• lots of dns requests from China, should I worry?

  - by nn4l

  I have turned on dns query logs, and when running "tail -f /var/log/syslog" I see that I get hundreds of identical requests from a single ip address: Apr 7 12:36:13 server17 named[26294]: client 121.12.173.191#10856: query: mydomain.de IN ANY + Apr 7 12:36:13 server17 named[26294]: client 121.12.173.191#44334: query: mydomain.de IN ANY + Apr 7 12:36:13 server17 named[26294]: client 121.12.173.191#15268: query: mydomain.de IN ANY + Apr 7 12:36:13 server17 named[26294]: client 121.12.173.191#59597: query: mydomain.de IN ANY + The frequency is about 5 - 10 requests per second, going on for about a minute. After that the same effect repeats from a different IP address. I have now logged about 10000 requests from about 25 ip addresses within just a couple of hours, all of them come from China according to "whois [ipaddr]". What is going on here? Is my name server under attack? Can I do something about this?

• How do I force apt-get to install a package that will not install due to a bug introduced by Ubuntu 11.10?

  - by Hemm

  Ubuntu 11.10 separated out python-profiler from the Python standard library due to licensing philosophies. (According to what I could Google, correct me if I'm wrong.) This is an active bug since October for 11.10. I have Python 2.7.2 installed, so the dependency errors are wrong. 'apt-get check' does not resolve the problem. What is the best way to resolve to this? Thank you. sudo apt-get install python-profiler Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: python-profiler : Depends: python (>= 2.5) but it is not going to be installed Depends: python (< 2.8) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

• What technology or skillset should I learn today in order to be able to charge $250+ / hr in 2-3 years? [closed]

  - by Ryan Waggoner

  I've been doing PHP freelance development for the last 4-5 years and I'm starting to max out my hourly rate. So in 2010 I decided to transition to a new language. I played with Python and Ruby, but ended up settling on iOS, for three reasons: I'm enjoying the challenge of working on a completely different type of development, instead of another flavor of web development The demand seems higher right now than for Ruby or Python I see iOS developers charging $150 - 250 / hr Whether these reasons are right or wrong, I've been learning iOS for the last year and I'm starting to get more work in that field. I feel confident that in six months (barring any major shifts in the ecosystem), I can be billing iOS work at $150 / hr or more. However, I'm feeling that I should have done this earlier, that I've missed the boat, and that iOS development is going to dry up or get much more commoditized. Whether this is true or not isn't really my question (though feel free to comment). What I want to know is: what should I start learning right now so that I can be ahead of the curve in a couple years when the demand is far outstripping supply? What technologies or skillsets are going to be so heavily in demand in 2-3 years that you'll be able to charge $250 / hr or more and stay busy? These don't have to be new technologies either...the answer could be iOS or COBOL or whatever.

• Understanding Asynchronous Programming with .NET Reflector

  - by Nick Harrison

  When trying to understand and learn the .NET framework, there is no substitute for being able to see what is going on behind at the scenes inside even the most confusing assemblies, and .NET Reflector makes this possible. Personally, I never fully understood connection pooling until I was able to poke around in key classes in the System.Data assembly. All of a sudden, integrating with third party components was much simpler, even without vendor documentation!With a team devoted to developing and extending Reflector, Red Gate have made it possible for us to step into and actually debug assemblies such as System.Data as though the source code was part of our solution. This maybe doesn’t sound like much, but it dramatically improves the way you can relate to and understand code that isn’t your own.Now that Microsoft has officially launched Visual Studio 2012, Reflector is also fully integrated with the new IDE, and supports the most complex language feature currently at our command: Asynchronous processing.Without understanding what is going on behind the scenes in the .NET Framework, it is difficult to appreciate what asynchronocity actually bring to the table and, without Reflector, we would never know the Arthur C. Clarke Magicthat the compiler does on our behalf.Join me as we explore the new asynchronous processing model, as well as review the often misunderstood and underappreciated yield keyword (you’ll see the connection when we dive into how the CLR handles async).Read more here

• How does a game developer get feedback from gamers (not developers) or start a forum community without paying for advertising or hiring Q&A teams?

  - by Carter81

  I am familiar with a lot of game developer forums, but I'd assume this is much less likely to attract more casual commentators. I also fear that feedback from a gamer's perspective would often be tainted by their game dev perspective. For example, if I were making a RTS game and wanted to get feedback from "The RTS gamers" where would I go? Is there a general idea of what type of website or forum to go to? Do you go to specific game websites, to try to "steal" attention? Would this not equate to spam or inappropriate posting? What is considered appropriate and inappropriate? I am not asking for specifics. I am asking how one "starts a community", or how one "gets feedback from gamers" without resorting to spamming forums or 'advertising' just to see what sticks. What TYPE OF PLACE does one go? Are there already sites designed for this purpose? I tried going to what was once a very popular forum for feedback from what I believed was a niche hardcore group of gamers in the genre, but its popularity seemed to have died significantly; Leaving only trolls and very young teenagers. The resulting feedback was quite disappointing, mainly for how little feedback it resulted. Many years ago, feedback would flood in by the hundreds so quickly. Without this website, I am at a loss as to where to go to see what people think of ideas, gather feedback from a gamer's perspective (not a developer's perspective), or where to pull from to start my own site's forum. I am out of ideas of what to do, short of going to various game forums to post in the off-topic sections there.

• Reliable procedure/tool for removing print drivers in Windows 7 (domain environment)

  - by ultrasawblade

  One of the troubleshooting steps in resolving printer-related issues with any version of Windows is to remove installed print drivers and then reinstall the drivers. This is a domain environment and drivers are pulled from a print server. I've had occasion to need to do this on a user's system running Windows 7 Enterprise 64-bit. These procedures don't work: Removing the printer from Devices and Printers (doesn't remove driver obviously) Doing the above, going into Server Properties, and attempting to remove the driver (fails with a "driver in use" error) Opening an empty mmc, adding the Print Management snap-in, and attempting to do the above. Doing sc stop spooler and sc start spooler before doing both of the above Now I know it's possible to remove drivers with the spooler service stopped and then going into the spool directory, as well as deleting registry entries. I'm asking if a tool exists to do this where I can just select the driver in question and it be removed.

• CA For A Large Intranet

  - by Tim Post

  I'm managing what has become a very large intranet (over 100 different hosts / services) and will be stepping down from my role in the near future. I want to make things easy for the next victim person who takes my place. All hosts are secured via SSL. This includes various portals, wikis, data entry systems, HR systems and other sensitive things. We're using self signed certificates which worked o.k. in the past, but are now problematic because: Browsers make it harder for users to understand exactly what is going on when a self signed certificate is encountered, much less accept them. Putting up a new host means 100 phone calls asking what "Add an exception" means What we were doing is just importing the self signed certs when we set up a new workstation. This was fine when we only had a dozen to deal with, but now its just overwhelming. Our I.T. Department has classified this as ya all's problem, all we get from them is support for switch and router configurations. Beyond the user having connectivity, everything else is up to the intranet administrators. We have a mix of Ubuntu and Windows workstations. We'd like to set up our own self signed CA root, which can sign certificates for each host that we deploy on the intranet. Client browsers would of course be told to trust our CA. My question is, would this be dangerous and would we be better off going with intermediate certificates from someone like Verisign? Either way, I still have to import the root for the intermediate CA, so I really don't see what the difference is? Other than charging us money, what would Verisign be doing that we could not, beyond protecting the root CA cert so it can't be used to make forgeries?

• Interview Questions in OOP

  - by Fero

  Hi all, I faced the below interview questions in OOP under PHP language. Kindly clear my clarifications regarding this. I am very confused. As i am a beginner to OOP i got too confused. Could anyone clarify these things clearly? Difference between Abstract class and interface. Interviewer : Let us consider abstract class contains three abstract methods such as a,b,c and interface contains three methods a,b,c. In this case these do the same functionality. Then why are going for abstract and why are we going for interface. Me : ? static keyword. Interviewer: We call static method without creating object by using scope resolution operator in PHP. As well as we can able to call concrete methods also. Then what is need of static keyword there? Me : .... final keyword. Interviewer: Give me any scenario of using final keyword. Me : For db connection related method Interviewer: Other than that? Me: ... Constructor. Interviewer: What is the use of constructor? Me : There is no need for object to access this. It will call automatically when the class calls. Interviewer: Other than that? Me : .... Thanks in advance...

• Designing generic render/graphics component in C++?

  - by s73v3r

  I'm trying to learn more about Component Entity systems. So I decided to write a Tetris clone. I'm using the "style" of component-entity system where the Entity is just a bag of Components, the Components are just data, a Node is a set of Components needed to accomplish something, and a System is a set of methods that operates on a Node. All of my components inherit from a basic IComponent interface. I'm trying to figure out how to design the Render/Graphics/Drawable Components. Originally, I was going to use SFML, and everything was going to be good. However, as this is an experimental system, I got the idea of being able to change out the render library at will. I thought that since the Rendering would be fairly componentized, this should be doable. However, I'm having problems figuring out how I would design a common Interface for the different types of Render Components. Should I be using C++ Template types? It seems that having the RenderComponent somehow return it's own mesh/sprite/whatever to the RenderSystem would be the simplest, but would be difficult to generalize. However, letting the RenderComponent just hold on to data about what it would render would make it hard to re-use this component for different renderable objects (background, falling piece, field of already fallen blocks, etc). I realize this is fairly over-engineered for a regular Tetris clone, but I'm trying to learn about component entity systems and making interchangeable components. It's just that rendering seems to be the hardest to split out for me.

• HTG Explains: What Is RSS and How Can I Benefit From Using It?

  - by Jason Fitzpatrick

  If you’re trying to keep up with news and content on multiple web sites, you’re faced with the never ending task of visiting those sites to check for new content. Read on to learn about RSS and how it can deliver the content right to your digital doorstep. In many ways, content on the internet is beautifully linked together and accessible, but despite the interconnectivity of it all we still frequently find ourselves visiting this site, then that site, then another site, all in an effort to check for updates and get the content we want. That’s not particular efficient and there’s a much better way to go about it. Imagine if you will a simple hypothetical situation. You’re a fan of a web comic, a few tech sites, an infrequently updated but excellent blog about an obscure music genre you’re a fan of, and you like to keep an eye on announcements from your favorite video game vendor. If you rely on manually visiting all those sites—and, let’s be honest, our hypothetical example has a scant half-dozen sites while the average person would have many, many, more—then you’re either going to be wasting a lot of time checking the sites every day for new content or you’re going to be missing out on content as you either forget to visit the sites or find the content after it’s not as useful or relevant to you. RSS can break you free from that cycle of either over-checking or under-finding content by delivering the content to you as it is published. Let’s take a look at what RSS is how it can help.

• How do I stop sound coming from my speakers with a faulty headphone socket?

  - by Andy

  On my laptop, I have a faulty headphone socket, so when I insert headphones into it, the speakers do not mute. I can confirm that this problem is caused by faulty hardware and not software as when I twist the headphone jack, the speakers come on and off according to the movements. On previous versions of Ubuntu, I worked around this problem by going into alsamixer and disabling "Auto-Mute Mode", and then going into the sound settings and choosing "Analog Headphones". However, on 12.04, no such option exists, rendering my headphones unusable with no way to work around the problem. I momentarily thought I had this problem fixed when I installed PulseAudio Volume Control from the Software Centre. I selected the Output Devices tab, and under "Built-in Audio Analogue Stereo" I selected "Headphones" for the port. However, this almost randomly seems to change back to "Speakers", despite me setting "Auto-Mute Mode" as disabled. Basically, I would like a way to permanently mute the speakers so only the headphones will play sound, without it losing my settings. It is ridiculous that such a simple setting has been taken away to "simplify" the user interface.

• As a developer, how do I learn sales? [closed]

  - by Dan Abramov

  I quit the company I was working for to pursuit an opportunity as a startup, and I believe in our product. I'm sure it's going to be great if we attract some customers first to keep going. (I don't want funding.) Our product is targeted at private schools and courses, and helps organize the mess other LMSs introduce. The problem is, our team is basically just me and I have very little idea about sales and marketing. I can do reasonably good copywriting but I'm sure I can do better—and being nervous or too techy in a real world conversation with the client doesn't help. I want to get better, in fact, a lot better at negotiating with clients and pitching my product. I did look for some “sales articles” on the web, and a lot of what I found is plain bullshit on SEO-engineered websites promoting books or $5000 courses. What I need instead is a developer's perspective on how to sale a product you think is great. What are typical programmer's mistakes and misconceptions about sales, and how to avoid them? How do you evolve into a reasonably great salesman? I can't believe it's in the mindset and unlearnable. Your own experience, combined with great articles available on the web is most welcome. To Future Readers The question got closed because it is not a good fit for this site. I found some helpful tips in a similar question asked on a sister StackExchange site about startups: I'm a terrible salesperson. What can I do about it?

• 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.

• Ubuntu 12.04 Frequent Kernel Panics

  - by Jordan Johns

  Dealing with what seems to be quantum behavior here. I'm having frequent Kernel panics and the problem is very hard to locate. To cut to the chase of what is going on I am essentially getting this screen: This occurs always after login (login screen is fine, can go into my TTY's and everything). But once I log in I have anywhere from 0 (instant) to 10 seconds before everything grinds to a halt and freezes. The only way I found out that it was a kernel panic was going into a TTY while it happens. At first, I figured something must be wrong with memory. Ran memtest86, full standard test. No errors. OK. CPU problem? Windows works fine, ran prime95 and a bunch of other torture tests for many hours. Drive problem? Nope. fsck reports no problems and the smart status is ok. Overclocking problem? Nope. Windows is working fine, and I also reset the bios to prove the point it was not the cause. At a loss here, even trying to reinstall the thing it gives me the same problem even attempting to install ubuntu (like right after you try to select "install ubuntu" or "try ubuntu first before installing"). Anyone have any thoughts? Its very bizarre, its as if my system hates linux and is trying to tell me not to use it (that would be a terrible reality). Thanks!

• Secure Apache Virtual Hosts?

  - by Dr Hydralisk

  I am going to host a few small sites on VPS, and each of them are going to run my own custom PHP scripts. I am fairly certain that they are secure (did everything in the book, plus some of which is not in the book) to make sure they can't be exploited. But just to be safe I want to know how I could secure each of the virtual hosts so that they can't escape from there virtual host (if a hacker uploaded a shell they could not go above the www folder a legitimate user can't do in ftp no matter how many times they click ..) folder on Debian and Apache.

• Deleted one membership table. Possible to import without breaking relationship?

  - by superexsl

  Hey, I hope this isn't going to be tricky/time consuming, so fingers crossed. I'm working with the ASP.NET membership table. However, I've got quite a few other tables that I've built, and most of them have a relationship with the dbo.aspnet_Membership table. I've accidentally deleted the dbo.aspnet_Membership table and can't get it back. There was no major data on it, (as it's on my local machine), but I would really like to copy and paste that one table from another database I have, mainly for the sake of not breaking the schema. Is this possible? I'm worried if I run the Aspnet_regsql.exe tool, it's going to break the schema and remove all data from the tables as well the relationships (which would take a while to re-establish). Is there any way I can import just the dbo.aspnet_Membership table into my current database? Thanks for the any advice!
