• Blueprints API for Oracle NoSQL Database

  - by Charles Lamb

  Here's an implementation of the Blueprints API for Oracle NoSQL Database. https://github.com/dwmclary/blueprints-oracle-nosqldb Blueprints is a collection of interfaces, implementations, ouplementations, and test suites for the property graph data model. Blueprints is analogous to the JDBC, but for graph databases. As such, it provides a common set of interfaces to allow developers to plug-and-play their graph database backend. Moreover, software written atop Blueprints works over all Blueprints-enabled graph databases. Within the TinkerPop software stack, Blueprints serves as the foundational technology for: Pipes: A lazy, data flow framework Gremlin: A graph traversal language Frames: An object-to-graph mapper Furnace: A graph algorithms package Rexster: A graph server

• new hard drive on Dell Adaptec 2610SA 6 port SATA RAID PCI card

  - by Ragnarok85

  I have a Dell Adaptec 2610SA 6 port SATA RAID PCI card with 3 hard drives on it and everything works fine. I plugged another hard drive to it and the system (Ubuntu 12.04, 64 bit) seems not to recognize it. Strange thing is that, as happened in the past, if I re-install the system, it recognizes the new hardware plugged to RAID card. Of course I don't want to re-install ubuntu each time I plug a new hard drive on my RAID card. Any idea? Thank you in advance

• Developing GLSL Shaders?

  - by skln

  I want to create shaders but I need a tool to create and see the visual result before I put them into my game. As to determine if there is something wrong with my game or if it's something with the shader I created. I've looked at some like Render Monkey and OpenGL Shader Designer from what I recall of Render Monkey it had a way to define your own attributes (now as "in" for vertex shaders = 330) easily though I can't remember to what extent. Shader Designer requires a plugin that I didn't even bother to look at creating cause it's an external process and plugin. Are there any tools out there that support a scripting language and I could easily provide specific input such as float movement = sin(elapsedTime()); and then define in float movement; in the vertex shader ? It'd be cool if anyone could share how they develop shaders, if they just code away and then plug it into their game hoping to get the result they wanted.

• 12.04 drops Wired Network if Wireless connects

  - by mitt10tim

  This is a little different then most of the questions I have seen here. When I am at my office I keep my Lenovo Thinkpad t61p running Ubuntu 12.04 x64 connected via wired Ethernet. I also typically leave the wireless radios on. After a recent update the behavior of laptop in regards to the networks has changed. It used to be that if the laptop had a wired connection, the wired would supersede the wireless. Now, when I get to work and plug the laptop in and power it up, it connects via wired (correct behavior), shortly after the wireless begins searching for its favorite network (also correct) but as soon as it finds a network to connect to, I lose Internet. If I disconnect from the wireless network, leaving the wireless radios powered on, and refresh the wired connection, all is well again. Powering down the wireless radios also corrects the problem. How can I set this up so that the wired network (if available) always has precedence over the wireless?

• How do I control Front and Back volume independently with cloned stereo signal

  - by someguy1984

  hello I have my 7.1 soundcard set to stereo and plugged in two stereo thingies (a. my desktop speakers b. my stereo) to the front respectively rear plug. Now I would like to an easy way to mute/volume control them independently - gui if possible. If I set my soundcard to 4.0, the pulse audio mixer gives me sliders for front and back but the problem is that's the input signal. so if i mute the front there and I'm listening to stereo everything remains silent. But what I'd have liked in that scenario would be the front to be silent and the back playing the full stereo signal. Is there a way to do that or something similar?

• Ubuntu 12.10 WiFi Problems

  - by Sean Webber

  I have a 32 bit machine running Ubuntu 12.10 with WiFi on it. I have a WPA2 network at home, but if I leave the USB Adapter plugged in while it boots, it infinitely keeps asking for the network password but never connects. If I plug it in after boot, it will connect but then I can't access ANYTHING on the LAN or Internet because "the DNS servers are unreachable". Now, if I leave the computer on a while, I get lucky sometimes and it MAGICALLY decides to connect for a little bit, lock the machine though and the Internet's gone again. The weirdest thing, is when I am connected but can't get to the internet, I do a netstat or ifconfig wlan0, I do have an IP address and everything. It says I'm connected but its not. I have a Realtek RTL8188CU USB adapter.

• PCI hotplug doesn't seem to work

• HDMI signal interrputs after 10 minutes plugged in a TV

  - by desert_unbound

  Ubuntu 11.10, Dell Inspiron N4050, VLC, Jupiter I'm trying to watch movies through HDMI output on a TV, with VLC, with the notebook unplugged from AC (but with enough battery for 2-3 hours of use), just with TV display (the notebook display stays off) And from 10 to 10 minutes, the TV turns black, and according to the TV, the HDMI cable is unplugged. But using the touchpad makes the screen appear again. In "screen" options, on system settings, i've set the screen to never turn off, and never reduce brightness using battery. In "power" settings, i've set to not suspend when using battery. In Jupiter, i've set (while trying to watch the movie) to work in maximum performance. I'm pretty sure it's not VLC, because i've set it to override power options and screensaver options (and also im not using xscreensaver). Also the movie continues, when the screen is black Maybe there's something that i'm missing? When i plug the HDMI in the notebook, i use jupiter to change the display (using the option "external display only")... maybe is that ?

• Sound issue in Lubuntu

  - by jvsa90

  I'm recently having a problem in my Lubuntu deskptop: sound through the speakers doesn't seem to work. The funny thing is: it works when I plug in my earphones. I've tried to unmute everything with pavucontrol and alsamixer, but everything seems to be OK. $ sudo aplay -l **** Liste der Hardware-Geräte (PLAYBACK) **** Karte 0: Intel [HDA Intel], Gerät 0: HDA Generic [HDA Generic] Sub-Geräte: 0/1 Sub-Gerät #0: subdevice #0 $ lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Device 034a Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at 58200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel Can anyone guess what's happening?

• USB Mouse/Keyboard not working

  - by crstn

  I installed Ubuntu 11.10 after booting it from a USB drive. Everything worked fine there, after booting the keyboard worked in grub but not after Ubuntu was booted. I can unplug either of them and plug them in via a PS2/USB adapter and the device will work. After switching a couple of times, I got the keyboard and mouse both working via usb but after I rebooted either stopped working. How can I fix this? The mouse is a Razer Krait and the keyboard is a Logitech ClassicKeyboard 200.

• Visual Studio Setup - why is solution explorer on the right?

  - by amelvin

  Every time I install VS (whichever version going back years) it installs with the Solution Explorer on the right. Now as most UIs have the navigation in a left hand column (and at the top of the viewport) and the content to the right of this navigation this always seems wrong to me. So I drag the solution explorer to the left of the screen and dock it there. But I've never seen another developer do this. Considering how most programmers usually like to customize their environment, adding their favourite text editor, browser, plug-ins, greasemonkey scripts etc why do Visual Studio developers never seem to make this simple UI change? Does anyone else do this or am I just screaming in the dark?

• 3G dongle and memory card detection

  - by user212632

  My questions is about 3G dongle (Huawei E1752) that I use for my internet on Ubuntu 12.04. The big issue is that ubuntu only recognise the dongle if I plug it in before booting up. But if somehow I loses connection (due to network being low) then the only way to use the 3G dongle again is to reboot my machine, which becomes a pain. I have the same issue with the memory card reader of my laptop whereby it only reads when I insert the card before booting up. My laptop is an Acer V3 -571g. At first I thought it was an issue that the model was quite new, but I have been updating my ubuntu for a while, and this issue has kept being the same

• How do I create tileable solid noise for map generation?

  - by nickbadal

  Hey guys, I'm trying to figure out how to generate tileable fractals in code (for game maps, but that's irrelevant) I've been trying to modify the Solid Noise plug-in shipped with GIMP (with my extremely limited understanding of how the code works) but I cant get mine to work correctly. My modified code so far (Java) GIMP's solid noise module that I'm basing my code off of (C) Here is what I'm trying to achieve but This is what I'm getting So if anybody can see what I've done wrong, or has a suggestion how I could go about doing it differently, I'd greatly appreciate it. Thanks in advance. And if I'm asking way to much or if just a huge failure at life, I apologize.

• USB internet not accessible

  - by Eric

  I'm brand new to ubuntu and linux. We access internet from a usb stick issued by a local telephone company. When I plug the stick into the computer, I see the device listed under internet connections as a mobile broadband device but it is grayed out and inaccessible. I tried to create a new mobile broadband connection but my country (Gabon) is not listed and we have no payment plans per se (we pay from a pre-paid card system).. Any clues as to how I can get the system to recognize the internet connection? Thanks for any help...

  I have a code of a Plug In from an SDK. The code is in Debug Mode. I use Intel Compiler which only applies optimizations in Release Mode. Under configuration manager of the project only "Debug" mode is defined. How could I switch to "Release" mode and enable all Intel Compiler's optimizations? If I enable them on debug mode nothing is applied (Empty Report). I couldn't find the trick to do so. Thank You.

• Plugins in Ops Center and Cloud Control

  - by Owen Allen

  Cloud Control just released an updated plugin for Oracle Virtual Networking, so I thought I'd mention a bit about how both Ops Center and Cloud Control use plugins. On the Ops Center side, we have a plugin to connect Ops Center to Cloud Control, letting them share monitoring data. This guide explains how to install and use that plugin. In Cloud Control, they have a more extensive collection of plugins, letting you link Cloud Control with a variety of other products. The Cloud Control library plug-in tab goes into more detail about how you can use these plugins in your environment.

• Autodesk Maya et Qt : la version 2011 est la première à se baser sur Qt, uniquement pour le meilleur

  Autodesk vient de lancer une nouvelle version d'un de ses produits phare, Maya 2011. Cette version est un peu spéciale : elle est sortie en 2010, certes, mais c'est aussi la toute première version de Maya à se baser sur Qt ! Dans tous les derniers films d'animation, jeux vidéo, et tout ce qui se fait en trois dimensions, il est plus que très probable que des parties ont été créées à l'aide d'Autodesk Maya, un des logiciels de modélisation 3D les plus répandus et les plus avancés depuis une dizaine d'années. Ce logiciel, compatible avec les trois plateformes principales, Windows, Linux et Mac OS X, est à même d'animer les rêves les plus fous de n'importe quel studio d'animation. Si, auparavant, quelques plug-ins étaient réalisés avec Qt afin d'être compatible...
