  • What resources are there for creating a dedicated NES emulator box?

    - by normalocity
    Where do I start, and what communities should I get involved in, in order to achieve the following? Ideally, I'd like to have a box that does the following (doesn't have to do this out of the box, I'm just looking to be able to achieve these goals through configs and necessary dependencies): Either bypasses login, or auto login Auto-start FCEUX with options that will (a) automatically start a ROM of my choosing, and (b) go into full-screen mode. You can assume that before I get that far, I've already configured the input devices and video options. I'd like to create (or install, if it exists) a full-screen app that takes a list of ROMs, allows me to select one with a gamepad/arcade stick, and press a button to open that game Be able to map a button on a gamepad/arcade stick to the "Power off" or exit function of the emulator, such that it will take me back to the ROM selection screen. I've already successfully installed FCEUX and tested it with an arcade stick I own, so I'm not looking for an emulator installer guide. I don't know if the ROM selector app exists already, but I'm a Java developer, and could probably create one (so long as it's not too difficult to support controllers - I was thinking of using Slick2D for this - a gaming library that I'm already pretty familiar with). The goal would be a dedicated box that I have connected to my TV. I power it on. It boots up and starts the ROM selection app, which passes the proper parameters to FCEUX (or another emulator that I might switch to at a later time), and I'm ready to go. Basically an NES emulator as a real, living room console. Also, as far as mapping a controller button to functions in the app, well, I've also played around with hardware, and it would be pretty trivial for me to modify a gamepad to trigger key presses. I just don't want to go to that length if it's not necessary.

  • Keyboard freezes / stuck if a key pressed repeatedly

    - by Aziz Rahmad
    I use Acer 4530. This problem has happened long since Ubuntu 10.10 and now that I use 11.04 dual booted with Linux Mint 10. Everytime I press one key repeatedly, like when I read a long article in a website/ebook or when I play games which required me to press arrow keys repeatedly, it would randomly freeze. That is, whatever I press on keyboard has no effect, and that also happens with touchpad. However, the USB mouse works just fine. I later found out that it's not actually freeze but more like it's like the key stuck. For example when I play tetris which I usually press w (down) button repeatedly, after some times it would freeze. And if I put the cursor in, say, browser's address bar, it would type "wwww....." infinitely. The only way I could fix it is by suspend the laptop, either by using mouse or by closing the lid. And instead of suspended, in that case the laptop would automatically wake up and everything will be fine. (Usually my laptop would wake up after suspended by pressing any key) It has happened since the first time I use Ubuntu, 10.10, and it also happens in Linux Mint 10, and until now in Ubuntu 11.04. It never happened when I use Windows, though. Anyone has ever encounter similar problem? Anyone know how to fix it permanently? UPDATE I just recently installed Windows 7 and Windows 8 Development Preview and both have similar symptoms. So I declare that this problem is not OS specific, probably hardware problem.

  • SQLAuthority News – Download Whitepaper – Power View Infrastructure Configuration and Installation: Step-by-Step and Scripts

    - by pinaldave
    Power View, a feature of SQL Server 2012 Reporting Services Add-in for Microsoft SharePoint Server 2010 Enterprise Edition, is an interactive data exploration, visualization, and presentation experience. It provides intuitive ad-hoc reporting for business users such as data analysts, business decision makers, and information workers. Microsoft has recently released very interesting whitepaper which covers a sample scenario that validates the connectivity of the Power View reports to both PowerPivot workbooks and tabular models. This white paper talks about following important concepts about Power View: Understanding the hardware and software requirements and their download locations Installing and configuring the required infrastructure when Power View and its data models are on the same computer and on different computer Installing and configuring a computer used for client access to Power View reports, models, Sharepoint 2012 and Power View in a workgroup Configuring single sign-on access for double-hop scenarios with and without Kerberos You can download the whitepaper from here. This whitepaper talks about many interesting scenarios. It would be really interesting to know if you are using Power View in your production environment. If yes, would you please share your experience over here.

  • Virtually the fastest way to try Solaris 11 (and Solaris 10 zones)

    - by dminer
    If you're looking to try out Solaris 11, there are the standard ISO and USB image downloads on the main page.  Those are great if you're looking to install Solaris 11 on hardware, and we hope you will.  But if you take the time to look down the page, you'll find a link off to the Oracle Solaris 11 Virtual Machine downloads.  There are two downloads there:A pre-built Solaris 10 zoneA pre-built Solaris 11 VM for use with VirtualBoxIf you're looking to try Solaris 11 on x86, the second one is what you want.  Of course, this assumes you have VirtualBox already (and if you don't, now's the time to try it, it's a terrific free desktop virtualization product).  Once you complete the 1.8 GB download, it's a simple matter of unzipping the archive and a few quick clicks in VirtualBox to get a Solaris 11 desktop booted.  While it's booting, you'll get to run through the new system configuration tool (that'll be the subject of a future posting here) to configure networking, a user account, and so on.So what about that pre-built Solaris 10 zone download?  It's a really simple way to get yourself acquainted with the Solaris 10 zones feature, which you may well find indispensible in transitioning an existing Solaris 10 infrastructure to Solaris 11.  Once you've downloaded the file, it's a self-extracting executable that'll configure the zone for you, all you have to supply is an IP address for the zone.  It's really quite slick!I expect we'll do a lot more pre-built VM's and zones going forward, as that's a big part of being a cloud OS; if there's one that would be really useful for you, let us know.

  • MaaS minimum requirements with juju-jitsu?

    - by Christopher Shen Mu Long
    I've browsed through so many different sites and found so much contradictory information. As I am getting tired of this and do belive this question affects many other users, so I would like to collect the "once and for all times" answer. Unfortunately, the documentation on MaaS and Juju is ... well, not the best, sorry to say that. What are the minimum system requirements for setting up a MaaS cluster, which is going to be orchestrated with juju-jitsu? Do they need to have the exact system specifications or can I just combine different hardware? What are the minimum requirements for the master machine? E.g. "You need at least 8GB of RAM, a dual core CPU with at least 3.0 GHz." How many machines to I need to deploy MaaS on? I've read six machines, nine machines, and so on. I clearly want to know: "You need one for the Master and e.g. five nodes." Do I need to attach as many NICs (network interface cards) to my master machine as there are nodes, or can I simply attach two NICs and a switch? One NIC for connecting to the internet, one for handling the MaaS tasks, connected to a switch, which connects my nodes to the master? Is Juju now ready for local deployment? The last time I experimented with juju and had to reboot my machine, the services orchestrated by juju were gone. This was an issue I also found on the official juju site. Unfortunately, as mentioned above, the documentation is not the best, so I could not find the necessary info on that again. So: Can I use juju on a local environment or will a reboot break my setup?

  • Be There: Tinkerforge/NetBeans Platform Integration Course

    - by Geertjan
    Tinkerforge is an electronic construction kit. It exposes a number of API bindings, including, of course, Java. The nice thing also is that Tinkerforge products are open source, both on the hardware and software levels, so that you can take their bases as a starting point for your own modifications. "The TinkerForge system is a set of pre-built electronics boards that are built in such a way that you can stack the boards (known as bricks), attach accessories (known as bricklets), and have your prototype and and running quickly. Unlike systems, such as the Arduino or Launchpad, the TinkerForge has to be attached to a computer and the computer does all of the work. With an easy set of application programming interfaces (APIs) available in C/C++, C#, Java, PHP, and Ruby, the system is easy to interface and program over USB in a snap." (from this useful article) Henning Krüp, who has arranged several NetBeans Platform Certified Training Courses in the past, in the Nordhorn/Lingen area in Germany, had the inspired idea to focus the next course on integration with Tinkerforge. In other words, the whole course will be focused on creating a standalone Java desktop application that leverages the NetBeans Platform to interact with Tinkerforge! Interested in joining the course or setting up something similar yourself? The course organized by Henning will be held from 19 to 21 September, as explained here, together with contact details.  If you'd like to organize a similar course at a location of your choosing, leave a comment at the end of this blog entry and we'll set something up together!

  • Great Example of a Simple Cost-Benefit Analysis

    - by BuckWoody
    I saw a post the other day that you should definitely go check out. It’s a cost/benefit decision, and although the author gives it a quick treatment and doesn’t take all points in the decision into account, you should focus on the process he follows. It’s a quick and simple example of the kind of thought process we should have as data professionals when we pick a server, a process, or application and even platform software. The key is to include more than just the price of a piece of software or hardware. You need to think about the “other” costs in the decision, and then make the right one. Sometimes the cheapest option is the cheapest, and other times, well, it isn’t. I’ve seen this played out not only in the decision to go with a certain selection, but in the options or editions it comes in. You have to put all of the decision points in the analysis to come up with the right answer, and you have to be able to explain your logic to your team and your company. This is the way you become a data professional, not just a DBA. You can check out the post here – it deals with Azure, but the point is the process, not Azure itself: http://blogs.msdn.com/eugeniop/archive/2010/03/19/windows-azure-guidance-a-simplistic-economic-analysis-of-a-expense-migration.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • chrome memory and cpu footprint

    - by nmizar
    I've searched the forums for an answer but I couldn't find quite the answer I was looking for [1] , so I thought I it could as well be of interest to more people around here. I carry out a big part of my job on the browser (or for the browser, if you want to put it that way). I tend to use Chrome, because it's got natively many of the newest features that I need (DevTools stuff, mainly but not only). BTW, I'm usually running the last available Chrome version/build on a desktop Vaio with 4GB RAM and dual core CPU and Ubuntu 12.04 as distro and Gnome as window manager. So, I was curious about a) why does Chrome spawn so many threads even opening only three of four tabs and b) is there any way to allocate more memory to Chrome to prevent its performance from degrading? Thanks in advance, Nacho PS [1] I found threads about Chrome freezing or running out of memory but not about the reasons for this being so or for avoiding it to happen. PPS Of course, I could always buy a newer and more capable machine and that is exactly what I'm trying to evaluate: is this a question of outdated hardware or the problem will keep appearing on any (decently but not hugely sized) machine?

  • Architectural and Design Challenges with SOA

    With all of the hype about service oriented architecture (SOA) primarily through the use of web services, not much has been said about potential issues of using SOA in the design of an application. I am personally a fan of SOA, but it is not the solution for every application. Proper evaluation should be done on all requirements and use cases prior to deciding to go down the SOA road. It is important to consider how your application/service will handle the following perils as it executes. Example Challenges of SOA Network Connectivity Issues Handling Connectivity Issues Longer Processing/Transaction Times How many of us have had issues visiting our favorite web sites from time to time? The same issue will occur when using service based architecture especially if it is implemented using web services. Forcing applications to access services via a network connection introduces a lot of new failure points to the application. Potential failure points include: DNS issues, network hardware issues, remote server issues, and the lack of physical network connections. When network connectivity issues do occur, how are the service clients are implemented is very important. Should the client wait and poll the service until it is accessible again? If so what is the maximum wait time or number of attempts it should retry. Due to the fact of services being distributed across a network automatically increase the responsiveness of client applications due to the fact that processing time must now also include time to send and receive messages from called services. This could add nanoseconds to minutes per each request based on network load and server usage of the service provider. If speed highly desirable quality attribute then I would consider creating components that are hosted where the client application is located. References: Rader, Dave. (2002).

I saw other place (I don't remember which site) They said, some times, when in windows, if bluetooth disabled by windows driver, It can't be enabled by linux. So, I should install windows and enable blueethooth from windows and then re install linux. That is impossible for me, because I don't have Windows installation media. But I tried this, which is I installed windows xp on virtual box. Vbox showed me thow unknow USB devices. I connected them and installed windows bluethooth drivers to xp. But it didn't ditected Bluethooth either. Also, when I set off mode in hardware switch, those unknown devices disappear from Vbox usb device seletcion menu. So, they are definitely something to do with wifi or bluethooth. Please help me..

  • Where do I start in regards to making a Gnome/Unity Form Application

    - by JMK
    Ok so I am familiar with developing Form and Console applications on Windows using Visual Studio .Net with C#, but where do I start when it comes to Linux distro's like Ubuntu, is there an equivalent? How would one go about matching what they can do in a Windows environment with .Net and C# in a Linux environment without .Net coding in something like Java or C/C++? I am aware of Eclipse, does eclipse have a form designer or do you have to code the design of any Gnome/Unity forms manually? Can I use eclipse to write the Linux equivalent of a console application, that you just double click on to run? I also know about Mono, but the idea is that I want to learn how to develop software without using anything in the Microsoft stack and am not sure where to start. What is the standard language/framework used to develop these types of applications on Linux? As I become more proficient with Visual Studio, C# and .Net, it has struck me that without these Microsoft tools, I am nothing. I am only capable of developing for the Microsoft OS and this scares me. This isn't some anti Microsoft thing, Microsoft makes some incredible Software/Hardware/Operating Systems/IDE's, but it is generally a bad idea to put all of your eggs in one basket so if I want to learn how to develop Terminal and Gnome/Unity form applications where in the world do I start? I have used Linux on and off for years, but Windows has been my primary OS. However I have watched Linux get better and better and as much as I love Windows 7, I am dubious about Windows 8 (I for one will sorely miss my start menu)! Obviously MS aren't going anywhere anytime soon and I could spend the the next couple of decades developing for .Net without any issues but just because you can get away with something doesn't always mean it's a good idea. Thanks

  • 12.04 LTS boot hangs at "SP5100 TCO timer: mmio address 0xfec000f0 already in use", didn't yesterday

    - by DarkIron112
    Dual-booting Windows 7 and Ubuntu 12.04 LTS. I went to reboot from Win to Ubu, and found a few interesting things. My POST screen is covered in blocks of epileptic colors until I hit GRUB, which continues when I try to boot into Ubuntu. These color blocks don't appear when I use my on-board VGA, so I'll just attribute to that. Grub dimensions are swapped (card vs onboard, probably), but, when interfacing with onboard VGA, the Grub Timeout Counter works and when using my card, it does not (see "[!!!]" below for more information) Booting into Ubuntu directly causes the error: SP5100 TCO timer: mmio address 0xfec000f0 already in use Booting into recovery mode, meanwhile, and then "resuming normal boot" gets me to the desktop without native 1440x900 resolution and graphic drivers can't tell the monitor it's looking at (I assume this is because it's not a full graphic boot, and as it says, some drivers won't run?) [!!!] When I reboot after going into recovery mode, the countdown timer works ONCE, puts me back into default ubuntu boot, and then does not work again until after another recovery-mode boot. Windows 7 can boot perfectly with no issues whatsoever from epilepsy color blocks or driver detection. This makes me wonder /why/ the POST screen can't handle my video card anymore. Amidst all the diagnostics, I opened my case and re-seated the videocard securely, ensuring it wasn't a loose connection-- But this did nothing to help me. Hardware I am running an NVidia GeForce GTX 8800 video card in a PCI slot. I have 4.8GiB memory, an AMD Athlon II Quad-core 640 Processor, on an MSI K9N6GM Series Mobo. Onboard video is an NVidia GeForce MCP61(V/S/P) card. Note: I did not have any of these problems yesterday, and I have been using Ubuntu intensively for a week, though it's been working flawlessly for months. I've recently been using it to mod my Android phone, perhaps I messed something up in the file system?

  • How is"cloud computing"different from "client-server"?

    - by BellevueBob
    Watching a CEO for a new "cloud computing" company describe his company on a finance TV program today, he said something like "Cloud computing is superior to old-fashioned client-server computing". Now I'm confused. Can someone please explain what "cloud computing" means in contrast to client-server? As far as I understand it, cloud computing is more of a network services model, such that I do not own or maintain the physical hardware. The "cloud" is all the back-end stuff. But I still might have an application that communicates with that "cloud" environment. And if I run a web site presents a form that a user fills out, pushes a button on the page, and returns some report that was generated by the web server, isn't that the same as "cloud" computing? And would you not consider my web browser as the "client"? Please note my question is specific to the concept of "cloud computing" with respect to "client-server". Sorry if this is an inappropriate question for this site; it's the one closest in the Stack universe and this is my first time here. I'm an old timer, programming since mainframe days in the late 70's.

  • NVIDIA proprietary driver logging me to console instead of GUI

    - by Woozie
    Firstly i want to apologise for any mistakes, English is not my native language. My problem is I can't get NVIDIA proprietary drivers to work. I tried to install it on Ubuntu 12.04.1 32 and 64 bits, Ubuntu 12.10 Beta 2, Linux Mint 13 Cinnamon 64 bits and openSUSE 12.2 64 bits and the error code and symptoms (logging to tty1 instead of GUI logging, low-res bootscreen) are the same for all of these distros. Right, I didn't tell what's the error code. It appears on sudo startx. NVIDIA: could not open the device file /dev/nvidia0 (Input/output error). I know that's the common problem, but I tried to blacklist or even remove the noveau drivers, install NVIDIA driver from repo/from official script/in "Additional drivers", editing xorg.conf and using Xorg -configurate and nvidia-xconfig, actualizing the kernel and entire distro and many, many things that I don't remember. But the problem is even better: entire Cinnamon (Mint) is freezing during the work. I found the error code, which appears during the freeze: Oct 1 20:57:17 WoozieLaptop kernel: [ 308.120176] [drm] nouveau 0000:01:00.0: PFIFO_CACHE_ERROR - Ch 4/1 Mthd 0z0060 Data 0xbcef0201 My Xorg.0.log is here.

  • AMD FX CPU drivers/patch

    - by Mubeen Shahid
    I am using Ubuntu since 2009 on notebooks with Intel CPUs. However now, that I am using AMD's FX 6300, I am interested in knowing if there exists anything from Ubuntu (specifically any kernel enhancements/drivers/patches) for AMD's FX "family 15h" Piledrivers. Reason: I would like to have a kernel which uses the hardware to its full capacity, be able to use the latest instruction sets, for max. performance. I did some tests, started with compiling stable 3.9.7 on my 12.04 LTS box, and during compilation I choose processor vendor AMD (unchecked Intel/VIA/etc.), and when I started Ubuntu with this compiled kernel, in the section "System Settings - Additional Drivers" I found that, in addition to graphic card's drivers, there were AMD family 15h drivers also. However, I would prefer something in this regard tested/signed by Ubuntu developers. P.S: 1- the kernel that I have compiled has some issues with Nvidia graphics drivers, so I deleted kernel 3.9.7 and installed signed 3.8.xx from Ubuntu repositories. 2- incase if somebody is planning to advise me to install "AMD64", I am not talking about AMD64 (which is in fact for 64-bit platform).

  • Is these company terms good for a programmer or should I move?

    Here are some of the terms and conditions set forward by my employer. Does these make sense for a job like programming? No freelancing in any way even in your free time outside company work hours (may be okay. May be they wanted their employees to be fully concentrating on their full time job. Also they don't want their employees to do similar work for a competing client. Completely rational in that sense). - So sort of agreed. Any thing you develop like ideas, design, code etc while I'm employed there, makes them the owner of that. Seriously? Don't you think that its bad (for me)? If I'm to develop something in my free time (by cutting down sleep and hard working), outside the company time and resource, is that claim rational? I heard that Steve Wozniak had such a contract while he was working at HP. But that sort of hardware design and also those companies pay well, when compared to the peanuts I get. No other kind of works allowed. Means no open source stuffs. Fully dedicated to being a puppet for the employer, though the working environment is sort of okay. According to my assessment this place would score a 10/12 in Joel's test. So are these terms okay especially considering the fact that I'm underpaid with peanuts?

  • Raspberry Pi and Java SE: A Platform for the Masses

    - by Jim Connors
    One of the more exciting developments in the embedded systems world has been the announcement and availability of the Raspberry Pi, a very capable computer that is no bigger than a credit card.  At $35 US, initial demand for the device was so significant, that very long back orders quickly ensued. After months of patiently waiting, mine finally arrived.  Those initial growing pains appear to have been fixed, so availability now should be much more reasonable. At a very high level, here are some of the important specs: Broadcom BCM2835 System on a chip (SoC) ARM1176JZFS, with floating point, running at 700MHz Videocore 4 GPU capable of BluRay quality playback 256Mb RAM 2 USB ports and Ethernet Boots from SD card Linux distributions (e.g. Debian) available So what's taking place taking place with respect to the Java platform and Raspberry Pi? A Java SE Embedded binary suitable for the Raspberry Pi is available for download (Arm v6/7) here.  Note, this is based on the armel architecture, a variety of Arm designed to support floating point through a compatibility library that operates on more platforms, but can hamper performance.  In order to use this Java SE binary, select the available Debian distribution for your Raspberry Pi. The more recent Raspbian distribution is based on the armhf (hard float) architecture, which provides for more efficient hardware-based floating point operations.  However armhf is not binary compatible with armel.  As of the writing of this blog, Java SE Embedded binaries are not yet publicly available for the armhf-based Raspbian distro, but as mentioned in Henrik Stahl's blog, an armhf release is in the works. As demonstrated at the just-completed JavaOne 2012 San Francisco event, the graphics processing unit inside the Raspberry Pi is very capable indeed, and makes for an excellent candidate for JavaFX.  As such, plans also call for a Pi-optimized version of JavaFX in a future release too. A thriving community around the Raspberry Pi has developed at light speed, and as evidenced by the packed attendance at Pi-specific sessions at Java One 2012, the interest in Java for this platform is following suit. So stay tuned for more developments...

  • Yoga Pro 2 Wi-Fi not working

    - by user293004
    I installed Ubuntu 14.04 on my new Yoga Pro 2 and the wireless is not working. It started with Windows 8 on it. The Network Manager says Wi-Fi is disabled by hardware switch. I tried putting a blacklist file in ect/modprobe.d as has been suggested in many places. I called the file "blacklist-ideapad_laptop.conf" and wrote in the file blacklist ideapad_laptop I checked to make sure that the wireless is enabled in the BIOS. It is. I ran rfkill list all and it displayed: 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: yes I ran iwlist wlan0 scan and it displayed: wlan0 Failed to read scan data : Network is down I ran sudo rmmod ideapad_laptop and it displayed: rmmod: ERROR: Module ideapad_laptop is not currently loaded. I ran ifconfig wlp1s0 up and it displayed: wlp1s0: ERROR while getting interface flags: No such device. I ran "lspci" and it displayed: 01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b) I ran sudo lshw -c network and it displayed: *-network DISABLED description: Wireless interface product: Wireless 7260 vendor: Intel Corporation physical id: 0<br> bus info: pci@0000:01:00:0.0 logical name: wlan0 version: 6b serial: 7c:7a:91:5f:9b:fa width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.13.0-24-generic firmware=22.24.8.0 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:61 memory:b0400000-b0401fff This No wireless with Intel Centrino Advanced-N 7260 seems to be dealing with a similar issue. It suggests that I need to update my firmware. So I downloaded iwlwifi-7260-ucode-23.214.9.0 from Intel's website. I put the file "iwlwifi-7260-9.ucode" in /lib/firmware and ran "sudo lshw -c network" again. It displayed exactly as before. Is there something else I need to do install the new firmware?

  • Metaphor for task synchronization [closed]

    - by nkint
    I'm looking for a metaphor. A friend of mine taught me to use metaphors from nature, everyday life, math, and use them to design my projects. They can help in creating a better design or better understanding or the problem, and they are cool. Now I'm working on a project with hardware and micro-controllers in C. For convenience, I have decided to use multiple micro-controllers as co-processor units for real-time (the slaves) and a master. This has saved me a lot of headache: I can code the main logic in the master without paying too much attention to super optimizing everything; I don't care if I need some blocking-call; I don't worry about serial communication with the computer. I just send messages to the slaves and they are super fast super in real time. I like my design and it seems to work well. So here are the important concepts that I'm trying capture in the metaphor: hierarchy of processing Not using one big brain but rather several small, distributed brain units using distributed power or resources I'm looking for a good metaphor for this concept of having one unit synchronize the work of all the others. Preferably, the metaphor would come from nature, biology, or zoology.
