  • Ubuntu 12.10 - VirtualBox not sharing internet with guest system

    - by Fernando Briano
    I went from ArchLinux to Ubuntu on my dev box. I use VirtualBox to test web sites on Windows and IE. I have my Windows 7 VirtualBox image running on Ubuntu's VirtualBox. Back with ArchLinux, internet worked "out of the box" on the Windows boxes. I left the default options on the box's Network Options (NAT). The Windows machine shows as "connected to ethernet" but reports: The dns server isn't responding So I can't access Internet from there. I tried searching for Ubuntu's official docs but they seem pretty outdated. I tried using my old boxes from Arch (which boot normally but have no internet) and creating a new box from Ubuntu itself, but still get the same results. Update: I'm using VirtualBox 4.1.18 from Ubuntu's repository (apt-get install virtualbox).

  • Strange 401 (Unauthorized) when calling a WCF Service

    - by mipsen
    A WCF Service we call from BizTalk using WCF BasicHTTP usually works fine but all of a sudden it started returning 401 errors for some calls while others continued working as expected so it could not have been a "real" 401. The difference was the size of the message. One parameter of the service is a rather complex object. In the cases we got a 401 it got quite big (containing a lot of customer-data), say 5 MB. So we turned on tracking. The messages we traced out where about 20MB. Not too big for WCF one should suppose... A bit of research led us to increasing maxItemsInObjectGraph in the behaviours but that did not help. The service we call is in the same network as we are and is a WCF service. So we tried changing from BasicHTTP to net.tcp and Bingo! Ok, we had to use CustomBinding in BizTalk to set all the Quotas, etc. but it worked in the end.

  • What is the most secure way to archive a GKScore to be re-submitted later?

    - by Jonathan Sibley
    I'm looking for the safest way to archive and store a GKScore that needs to be re-submitted to Game Center (say, because the user didn't have a network connection at the time the score was earned). I would like to archive the GKScore instance in case the app is terminated before it can be successfully re-submitted to Game Center. My worry is that if it's archived to an instance of NSData and saved in a .plist, it would be easy to manipulate. Perhaps this worry is unjustified? NOTE: I posted a similar question on Stack Overflow only to realize that it's better asked here.

  • Bitbucket and a small development house

    - by Marlon
    I am in the process of finally rolling Mercurial as our version control system at work. This is a huge deal for everyone as, shockingly, they have never used a VCS. After months of putting the bug in management's ears, they finally saw the light and now realise how much better it is than working with a network of shared folders! In the process of rolling this out, I am thinking of different strategies to manage our stuff and I am leaning towards using Bitbucket as our "central" repository. The projects in Bitbucket will solely be private projects and everyone will push and pull from there. I am open to different suggestions, but has anyone got a similar setup? If so, what caveats have you encountered?

  • Design a Distributed System

    - by Bonton255
    I am preparing for an interview on Distributed Systems. I have gone through a lot of text and understand the basics of the area. However, I need some examples of discussions on designing a distributed system given a scenario. For example, if I were to design a distributed system to calculate if a number N is primary or not, what will the be design of the system, what will be the impact of network latency, CPU performance, node failure, addition of nodes, time synchronization etc. If you guys could present your in-depth thoughts on this example, or point me to some similar discussion, that would be really helpful.

  • ubuntu 11.10 CellC data card

    - by Armien
    In 11.10 I find that I can connect to the internet via broadband connection successfully. The problem is that I cannot have the data card attached to the machine while the machine boots up. If I leave the data card in the machine during startup, the data card is not picked up and I then cannot connect to the internet. I must first boot up my machine, login, attach the data card into the usb port, wait so 30 seconds. The broadband connection name will then appear in the network dropdown at the top of the screen. An internet connect is now possible via broadband. Please let me know what must be done to fix this. Thanks Armien

  • Wifi is connected but internet not working?

    - by Philip
    I have a lenovo x230 running ubuntu 12.04lts. I've been using it just fine for a while, but all of a sudden the internet's stopped working. It's connected to the router just fine (I can see the antenna bars saying it's connected) but when I try to go to a webpage, it's just loading forever. I've tried the fix listed here (http://ubuntuforums.org/showthread.php?t=1985079) but it hasn't done anything (the instructions are a little confusing though). I'm booting windows 7 right now and the internet works just fine when I'm on windows, so I know it must be a problem with ubuntu. I haven't touched any network settings before this problem happened, and I've been using it just fine for months, so I don't know why I'm getting this problem all of a sudden. Oh and I haven't updated anything in a few weeks (you know when the update manager pops up every so often listing all the things there's an update for) so I know it's not some update that broke it.

  • Thread problem with XNA C#

    - by Luis
    I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

  • ssh tunnel to a remote CUPS server

    - by drevicko
    There is a CUPS server beyond a firewall and I'd like to use it's printers. I have ssh access to computers that can access the CUPS server, and can get at the servers web interface by forwarding say port 1631. I cannot forward port 631 as I've not got root access to anything on the servers network. In Ubuntu's 'Printing' control panel, I can enter the address of a server, but I've not been able to connect through the forwarded port (localhost:1631, which is forwarded to the remote CUPS server's 631 port). Any ideas?

  • Building Enterprise Smartphone App &ndash; Part 2: Platforms and Features

    - by Tim Murphy
    This is part 2 in a series of posts based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. In the previous post I discussed what reasons a company might have for creating a smartphone application.  In this installment I will cover some of history and state of the different platforms as well as features that can be leveraged for building enterprise smartphone applications. Platforms Before you start choosing a platform to develop your solutions on it is good to understand how we got here and what features you can leverage. History To my memory we owe all of this to a product called the Apple Newton that came out in 1987. It was the first PDA and back then I was much more of an Apple fan.  I was very impressed with this device even though it never really went anywhere.  The Palm Pilot by US Robotics was the next major advancement in PDA. It had a simple short hand window that allowed for quick stylus entry.. Later, Windows CE came out and started the broadening of the PDA market. After that it was the Palm and CE operating systems that started showing up on cell phones and for some time these were the two dominant operating systems that were distributed with devices from multiple hardware vendors. Current The iPhone was the first smartphone to take away the stylus and give us a multi-touch interface.  It was a revolution in usability and really changed the attractiveness of smartphones for the general public.  This brought us to the beginning of the current state of the market with the concept of an online store that makes it easy for customers to get new features and functionality on demand. With Android, Google made this more than a one horse race.  Not only did they come to compete, their low cost actually made them the leading OS.  Of course what made Android so attractive also is its major fault.  It is so open that it has been a target for malware which leaves consumers exposed.  Fortunately for Google though, most consumers aren’t aware of the threat that they are under. Although Microsoft had put out one of the first smart phone operating systems with CE it had to play catch up and finally came out with the Windows Phone.  They have gone for a market approach between those of iOS and Android.  They support multiple hardware vendors like Google, but they kept a certification process for applications that is similar to Apple.  They also created a user interface that was different enough to give it a clear separation from the other two platforms. The result of all this is hundreds of millions of smartphones being sold monthly across all three platforms giving us a wide range of choices and challenges when it comes to developing solutions. Features So what are the features that make these devices flexible enough be considered for use in the enterprise? The biggest advantage of today's devices is network connectivity.  The ability to access information from multiple sources at a moment’s notice is critical for businesses.  Add to that the ability to communicate over a variety of text, voice and video modes and we have a powerful starting point. Every smartphone has a cameras and they are not just useful for posting to Instagram. We are seeing more applications such as Bing vision that allow us to scan just about any printed code or text to find information.  These capabilities have been made available to developers in the form of standard libraries for reading barcodes of just about an flavor and optical character recognition (OCR) interpretation. Bluetooth give us the ability to communicate with multiple devices. Whether these are headsets, keyboard or printers the wireless communication capabilities are just starting to evolve.  The more these wireless communication protocols grow, the more opportunities we will see to transfer data between users and a variety of devices. Local storage of information that can be called up even when the device cannot reach the network is the other big capability.  This give users the ability to work offline as well and transmit information when connections are restored. These are the tools that we have to work with to build applications that can be leveraged to gain a competitive advantage for companies that implement them. Coming Up In the third installment I will cover key concerns that you face when building enterprise smartphone apps. del.icio.us Tags: smartphones,enterprise smartphone Apps,architecture,iOS,Android,Windows Phone

  • Adsense ads are not a good fit for my site

    - by Ryan Grush
    I run an academic network for college students to communicate at particular universities and we run Google Adsense. The site pulls in a decent amount for a side project but our CTR is horrible <0.2% and our RPM is equally low. The problem lies in the fact that Google pegs us as an education site (which we are) but shows our users ads for U of Phoenix, Devry U and other for-profit universities. All of our users are students of the more higher-caliber institutions and therefore have no use for these ads. I've known about this problem for some time but I don't know what to do to show more relevant ads instead (i.e. Spring Break, school apparel, poker, sports, etc). What would be the best way to change this?

    I am helping out an NGO, called Orphans Found Fund, here in Arusha Tanzania setup a computer lab to teach students about Ubuntu and open source applications. I have installed Ubuntu 10.10 on all the systems. What I'm wondering about is how to tweak the systems so that the kids cannot: Delete or alter system files Alter the system settings Add or remove applications Exceed a time limit (like an Internet Cafe) Also as the administrator I would like to monitor the usage for another system to make sure that abuse of network is not taking place. Any advice is much appreciated. Brendon

    I have Ubuntu 12.04 on an older desktop PC, and I am finding it much harder to connect to a wifi connection than it should be. I have an iPhone with which I want to tether to it with Mifi 4.0, but I need to install ipheth which I can't do without internet on that computer. I am typing from my other windows pc with which i can download and move hings with thumb drives, but haven't gotten keryx to work. I also found a D-Link DWL-G520 HIGH SPEED 2.4GHZ (802.11G) WIRELESS 108MBPS PCI ADAPTER which I installed, but can't find a driver to put on a flashdrive to use it. If anybody has any ideas, they are appreciated. I am a noob, and I don't want to have to move the comp. downstairs to plug into the modem. PS: I also have a netgear USB network adapter, which doesn't work with my Ubuntu.

  • What is Happening vs. What is Interesting

    - by Geertjan
    Devoxx 2011 was yet another confirmation that all development everywhere is either on the web or on mobile phones. Whether you looked at the conference schedule or attended sessions or talked to speakers at any point at all, it was very clear that no development whatsoever is done anymore on the desktop. In fact, that's something Tim Bray himself told me to my face at the speakers dinner. No new developments of any kind are happening on the desktop. Everyone who is currently on the desktop is working overtime to move all of their applications to the web. They're probably also creating a small subset of their application on an Android tablet, with an even smaller subset on their Android phone. Then you scratch that monolithic surface and find some interesting results. Without naming any names, I asked one of these prominent "ah, forget about the desktop" people at the Devoxx speakers dinner (and I have a witness): "Yes, the desktop is dead, but what about air traffic control, stock trading, oil analysis, risk management applications? In fact, what about any back office application that needs to be usable across all operating systems? Here there is no concern whatsoever with 100% accessibility which is, after all, the only thing that the web has over the desktop, (except when there's a network failure, of course, or when you find yourself in the 3/4 of the world where there's bandwidth problems)? There are 1000's of hidden applications out there that have processing requirements, security requirements, and the requirement that they'll be available even when the network is down or even completely unavailable. Isn't that a valid use case and aren't there 1000's of applications that fall into this so-called niche category? Are you not, in fact, confusing consumer applications, which are increasingly web-based and mobile-based, with high-end corporate applications, which typically need to do massive processing, of one kind or another, for which the web and mobile worlds are completely unsuited?" And you will not believe what the reply to the above question was. (Again, I have a witness to this discussion.) But here it is: "Yes. But those applications are not interesting. I do not want to spend any of my time or work in any way on those applications. They are boring." I'm sad to say that the leaders of the software development community, including those in the Java world, either share the above opinion or are led by it. Because they find something that is not new to be boring, they move on to what is interesting and start talking like the supposedly-boring developments don't even exist. (Kind of like a rapper pretending classical music doesn't exist.) Time and time again I find myself giving Java desktop development courses (at companies, i.e., not hobbyists, or students, but companies, i.e., the places where dollars are earned), where developers say to me: "The course you're giving about creating cross-platform, loosely coupled, and highly cohesive applications is really useful to us. Why do we never find information about this topic at conferences? Why can we never attend a session at a conference where the story about pluggable cross-platform Java is told? Why do we get the impression that we are uncool because we're not on the web and because we're not on a mobile phone, while the reason for that is because we're creating $1000,000 simulation software which has nothing to gain from being on the web or on the mobile phone?" And then I say: "Because nobody knows you exist. Because you're not submitting abstracts to conferences about your very interesting use cases. And because conferences tend to focus on what is new, which tends to be web related (especially HTML 5) or mobile related (especially Android). Because you're not taking the responsibility on yourself to tell the real stories about the real applications being developed all the time and every day. Because you yourself think your work is boring, while in fact it is fascinating. Because desktop developers are working from 9 to 5 on the desktop, in secure environments, such as banks and defense, where you can't spend time, nor have the interest in, blogging your latest tip or trick, as opposed to web developers, who tend to spend a lot of time on the web anyway and are therefore much more inclined to create buzz about the kind of work they're doing." So, next time you look at a conference program and wonder why there's no stories about large desktop development projects in the program, here's the short answer: "No one is going to put those items on the program until you start submitting those kinds of sessions. And until you start blogging. Until you start creating the buzz that the web developers have been creating around their work for the past 10 years or so. And, yes, indeed, programmers get the conference they deserve." And what about Tim Bray? Ask yourself, as Google's lead web technology evangelist, how many desktop developers do you think he talks to and, more generally, what his frame of reference is and what, clearly, he considers to be most interesting.
