  • Oops, I left my kernel zone configuration behind!

    - by mgerdts
    Most people use boot environments to move in one direction.  A system starts with an initial installation and from time to time new boot environments are created - typically as a result of pkg update - and then the new BE is booted.  This post is of little interest to those people as no hackery is needed.  This post is about some mild hackery. During development, I commonly test different scenarios across multiple boot environments.  Many times, those tests aren't related to the act of configuring or installing zone and I so it's kinda handy to avoid the effort involved of zone configuration and installation.  A somewhat common order of operations is like the following: # beadm create -e golden -a test1 # reboot Once the system is running in the test1 BE, I install a kernel zone. # zonecfg -z a178 create -t SYSsolaris-kz # zoneadm -z a178 install Time passes, and I do all kinds of stuff to the test1 boot environment and want to test other scenarios in a clean boot environment.  So then I create a new one from my golden BE and reboot into it. # beadm create -e golden -a test2 # reboot Since the test2 BE was created from the golden BE, it doesn't have the configuration for the kernel zone that I configured and installed.  Getting that zone over to the test2 BE is pretty easy.  My test1 BE is really known as s11fixes-2. root@vzl-212:~# beadm mount s11fixes-2 /mnt root@vzl-212:~# zonecfg -R /mnt -z a178 export | zonecfg -z a178 -f - root@vzl-212:~# beadm unmount s11fixes-2 root@vzl-212:~# zoneadm -z a178 attach root@vzl-212:~# zoneadm -z a178 boot On the face of it, it would seem as though it would have been easier to just use zonecfg -z a178 create -t SYSolaris-kz within the test2 BE to get the new configuration over.  That would almost work, but it would have left behind the encryption key required for access to host data and any suspend image.  See solaris-kz(5) for more info on host data.  I very commonly have more complex configurations that contain many storage URIs and non-default resource controls.  Retyping them would be rather tedious.

  • No description for any page on the website is available in Google despite robots.txt allowing crawling

    - by Abhijit
    I seem to have the weirdest issue with Search Engine Optimization, and I asked the IT folks at my university, I asked people on Joomla forums and I am trying to sort this issue out using Google Webmaster Tools for more than 2 months to little avail. I want to know if I have some blatantly wrong configuration somewhere that is causing search engines to be unable to index this site. I noticed a similar issue with another website I searched for online (ECEGSA - The University of British Columbia at gsa.ece.ubc.ca), making me believe this might be a concern that people might be looking an answer for. Here are the details: The website in question is: http://gsa.ece.umd.edu/. It runs using Joomla 2.5.x (latest). The site was up since around mid December of 2013, and I noticed right from the get go that the site was not being indexed correctly on Google. Specifically I see the following message when I search for the website on Google: A description for this result is not available because of this site's robots.txt – learn more. The thing is in December till around March I used the default Joomla robots.txt file which is: User-agent: * Disallow: /administrator/ Disallow: /cache/ Disallow: /cli/ Disallow: /components/ Disallow: /images/ Disallow: /includes/ Disallow: /installation/ Disallow: /language/ Disallow: /libraries/ Disallow: /logs/ Disallow: /media/ Disallow: /modules/ Disallow: /plugins/ Disallow: /templates/ Disallow: /tmp/ Nothing there should stop Google from searching my website. And even more confusingly, when I go to Google Webmaster tools, under "Blocked URLs" tab, when I try many of the links on the site, they are all shown up as "Allowed". I then tried adding a sitemap, putting it in the robots.txt file. That did not help. Same exact search result, same behavior in the "Blocked URLs" tab on the webmaster tools. Now additionally, the "sitemaps" tab says for several links an error saying "URL is robotted out". I tried those exact links in the "Blocked URLs" and they are allowed! I then tried deleting the robots.txt file. No use. Same exact problem. Here is an example screenshot from Google's Webmaster Tools: At this point I cannot give a rational explanation to why this is happening and neither can anyone in the IT department here. No one on Joomla forums can seem to understand what is going on. Based on what I explained, does it seem that I have somehow set a setting in the robots.txt or in .htaccess or somewhere else, incorrectly?

  • Live-Ubuntu 12.04 ran fine, now stopped booting!

    - by user89743
    I've seen similar problems to this several times in the forum, but mine is a bit different, so the other posts I saw were no help to me. When I boot Ubuntu 12.04 64-bit from live-SD-card (3GB persistence) I suddenly get this error: (initramfs) mount: mounting /dev/loop0 on //filesystem.squashfs failed: Invalid argument Can not mount /dev/loop/0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs (it says I can type "help" for commands, but I don't know anything about how to go from there, totally new to linux) The reason I say my case is different is because my Ubuntu worked fine for over a week, even pretty fast, and now this problem happened. Before that I used to run my live ubuntu from USB sticks but that was slower (especially when booting which took 15 minutes from USB stick!). Also I kept getting the same above problem after a while when booting and had to re-create a live USB linux several times. Installing on harddrive is not an option because my harddrive has physical damage and getting a replacement will take a while, therefore I can only use live-USB or live-SD-card Ubuntu. As I said I used Ubuntu without problems for more than a week, before that as well for several weeks on USB sticks, but the above problem occured sooner or later. This time I paid attention to when it happened: I was rebooting my computer (HP 620 laptop, 4 GB RAM, 64 bit system) from SD flash card and when I was booting I selected F6 and then the first option "no acpi" or something like that...I had used it before and noticed it slowed down the time it took Linux to use. This time it caused this error. Now even when I boot normally/default I get this error. Now I'm accessing Ubuntu from my USB stick without persistence file, when I check my SD card, all the files mentioned in the error message are there and the filesystem.squashfs is 691.2 MB so nothing seems to have been deleted by accident. (I have already made many changes/downloaded programs to my SD card persistent Ubuntu and would hope to loose them, since downloading is expensive for me, and since the problem seems to re-occur...) Can anyone help me, preferably without having to create another startup disk on my SD card? I'm totally new to this. Sorry for the long posts, just didn't know what info is relevant and what isnt!

  • To make or not to make...python-nautilus a dependency?

    - by George Edison
    That is the question! Okay, all silliness aside, I really am forced to make a difficult decision here. My application is written in C++ and allows other scripts to invoke methods via XML-RPC. One of these scripts is a Nautilus extension written in Python. The extension is packaged with the rest of the application and copied to the appropriate place when installed (/usr/share/nautilus-python/extensions). Now the problem is that the Nautilus extension requires the python-nautilus package to be installed to be operational. So therefore I have three options: Make the python-nautilus package a dependency. This option will ensure that anyone who installs my package will be able to use the Nautilus extension. However, this option will not be attractive to XFCE or KDE users - a ton of python-nautilus's dependencies will be installed on their machines and take up a lot of space - even if they never use Nautilus. Put the python-nautilus package in the suggests: or recommends: field. This option provides the end-user with a way to avoid installing the python-nautilus package (by providing the --no-install-suggests or --no-install-recommends argument to apt-get). However, this won't work when the user installs the package in the Software Center. (I always get mixed up as to which of those two fields are installed by default.) Prompt the user when the application is installed or first launched. This option is more complicated than the others but offers the best compromise between making it easy for the user to install python-nautilus (without going into a technical explanation) and not installing it when the user doesn't need it (or want it). I guess the best way to implement this is a simple prompt that invokes apt-get if the user would like the package installed. Don't install the package at all. This option ensures that nobody has python-nautilus installed on their machine unless they want it. However, this also means that my Nautilus extension will simply not run on the end-user's machine unless they manually install the package. Which of these options seems the best choice? Have I missed any pros and cons for each of the options?

  • S11 launched

    - by unixman
    Now that Oracle Solaris 11 is out, its time to do 2 things -- 1) Its time to see what's in it, what's new and why its important, and then assess why it might make sense to begin evaluating it for your needs and 2) Its time to acknowledge, give thanks to and congratulate all the R&D personnel, architects, engineers, designers and testers who've put in so much effort and energy into helping make Solaris 11 (and SunOS 5.11) what it has become -- starting way back circa 2004 and, more importantly, culminating in the recent years and months -- staying focused on the execution, unwavering in the face of various challenges. For #1 above, here are a few good things to get going with - Watch the product launch replay - Visit the Solaris 11 Spotlight section on oracle.com - Get comfortable through introductory videos and detailed "how-to" guides (ex: how to create and publish IPS packages), white papers on the new default root file system, ZFS, and reap the benefits brought on by the fundamental shift in easing the administration experience - Look at the next level of software lifecycle management that is enabled by technologies such as Automated Installer and Image Packaging System -- that dramatically address patch management-related challenges - Understand how we continue to innovate in areas of service intelligence, reliability and availability - Start to evaluate enhancements in virtualization capabilities -- whether influenced by the need to consolidate or motivated by the need to have increased service mobility across physical systems, leveraging hardware-level abstractions - Gain more control over your network-centric services through enhancements in network resource management, observability and I/O performance - Look beyond your existing infrastructure with confidence that you can re-host and transition to newer systems with the use of Solaris 10 zones running on top of Solaris 11 - Relish in the fact that you can do all this, get your data to be secure and encrypted and more, on both, SPARC and x86-based systems. - Stay informed by keeping an eye on relevant blogs, which we've begun turning up recently. - Go through a hands-on lab - Sign up to take a class or just opt to watch various videos to begin to raise your comfort level with these technologies For #2 above -- There are many ways to do that. One way is to just say "thanks" with an email, a post, or a simple card,  similar to this one seen at a Barnes and Noble store recently.  The front of the card is followed by what's inside... and as the saying goes, now more then ever "it's what's inside that counts" And here's the inside of the card: So, what are you waiting for ? Go download and try it out, and please let us know what you think of it!

  • Ubuntu Linux won't display netbook's native resolution

    - by Daniel
    FYI: My Netbook model is HP Mini 210-1004sa, which comes with Intel Graphics Media Accelerator 3150, and has a display 10.1" Active Matrix Colour TFT 1024 x 600. I recently removed Windows 7 Starter from my netbook, and replaced it with Ubuntu 12.10. The problem is the OS doesn't seem to recognise the native display resolution of 1024x600 i.e. the bottom bits of Ubuntu is hidden beneath the screen & the only 2 available resolutions are: the default 1024x768 and 800x600. I've also thought about replacing Ubuntu with Lubuntu or Puppy Linux, as the system does run a bit slow, but I can't, as then I won't be able to access the taskbar and application menu which will be hidden beneath the screen. Only Ubuntu with Unity is currently usable, as the Unity Launcher is visible enough. I was able to define a custom resolution 1024x600 using the Q&A: How set my monitor resolution? but when I set that resolution, there appears a black band at the top of the screen and the desktop area is lowered, with bits of it hidden beneath the screen. I tried leaving it at this new resolution and restarting the system to see if the black band would disappear & the display will fit correctly, but it gets reset to 1024x768 at startup and displays following error: Could not apply the stored configuration for monitors none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 1)

  • IPS Package Groups

    - by Alan_Solaris_RE
    IPS group packages consist solely of dependencies on other packages that make up a logical grouping of software. These are similar to, but not the equivalent of, Solaris 10 metaclusters. The main difference is that metaclusters are nested subsets ranging from a minimal install to nearly all packages on the media. Group packages have no such hierarchy. They can overlap other groups, or be completely disjoint sets. A group dependency is set this way in an IPS package manifest file: depend fmri=full/pkg/name type=group Current Solaris Groups Solaris currently has 4 system groups defined. These are used for different types of installation, and are included in the xml manifest files used by the various Solaris installers: Package Name Summary Description Default Installation For:  group/system/solaris-desktop Oracle Solaris Desktop Provides an Oracle Solaris desktop environment Live Media  group/system/solaris-large-server Oracle Solaris Large Server Provides an Oracle Solaris large server environment Text Installer  group/system/solaris-small-server Oracle Solaris Small Server Provides a useful command-line Oracle Solaris environment  Zones  group/system/solaris-auto-install  Oracle Solaris Automated Installer Client  Provides an Oracle Solaris Automated Installer client  Automated Installer There are also several "feature" groups such as AMP and GNU Developer Tools. These are provided for convenience, but are not used directly by any installers. Retrieving Group Package Information A listing of all current groups can be found with the command: pkg info -r group/* A listing of all the packages in a group can be obtained with: pkg contents -o fmri -H -rt depend -a type=group groupname An example: $ pkg contents -o fmri -H -rt depend -a type=group solaris-desktop archiver/gnu-tar audio/audio-utilities codec/flac codec/libtheora codec/ogg-vorbis codec/speex communication/im/pidgin etc. You can determine which package group is currently installed on your system: $ pkg list group/system/\* Output would look like: NAME (PUBLISHER) VERSION IFO group/system/solaris-desktop 0.5.11-0.175.0.0.0.0.0 i-- Note that there are not version numbers associated with a group package dependency. The package version that best fits the system will be used, based on other dependencies such as what is listed in incorporation files. Installing a Group To Install a group, simple use the group package name as you would any other package: $ pkg install solaris-small-server  If you want to exclude a package from installing, you can use the --reject flag: $ pkg install --reject audio/audio-utilities solaris-desktop Creating Your Own Group To create your own group package, you can follow the pkg(5) documentation on how to create a package, and use this action for each package that is part of your group:   depend fmri=full/pkg/name type=group

  • How to Send the Contents of the Clipboard to a Text File via the Send to Menu

    - by Jason Faulkner
    We have previously covered how to send the contents of a text file to the Windows Clipboard with a simple Send To shortcut, but what if you want to do the opposite? That is: send the contents of the clipboard to a text file with a simple shortcut. No problem. Here’s how. Copy the ClipOut Utility While Windows offers the command line tool ‘clip’ as a way to direct console output to the clipboard, it does not have a tool to direct the clipboard contents to the console. To do this, we are going to use a small utility named ClipOut (download link at the bottom). Simply download and extract this file to a location in your Windows PATH variable (if you don’t know what this means, just extract the EXE to your C:\Windows folder) and you are ready to go. Add the Send To Shortcut Open your Send To folder location by going to Run > shell:sendto Create a new shortcut with the command: CMD /C ClipOut > Note the above command will overwrite the contents of the selected file. If you would like to append to the contents of the selected file, use this command instead: CMD /C ClipOut >> Of course, you could make shortcuts for both. Give a descriptive name to the shortcut. You’re finished. Using this shortcut will now send the text contents copied to your Windows Clipboard to the selected file. It is important to note that the ClipOut tool only supports outputting text. If you had binary data copied to your clipboard, then the output would be empty. Changing the Icon By default, the icon for the shortcut will appear as a command prompt, but you can easily change this by editing the properties of the shortcut and clicking the Change Icon button. We used an icon located in “%SystemRoot%\System32\shell32.dll”, but any icon of your liking will do. As an additional tweak, you can set the properties of the shortcut to run minimized. This will prevent the command window from “blinking” when the send to command is run (instead it will blink in your taskbar, which is hardly noticeable). Links Download ClipOut Utility

  • Dual booting windows 8/ubuntu 12.04.2, Grub doesn't appear and machine never boot in ubuntu

    - by black sensei
    i got a new ACER predator AG3620-UR308 which came with windows 8, so i wanted to run ubuntu 12.04.2 on it as a dual booting. To be honest, i've been doing dual booting for a while now so, i did the right thing. the box came with 2TB HDD. so i made 4 partitions with a raw partition just after the windows installation partition I always do manual installation so even if ubuntu didn't detect windows 8, it was ok for me. So i created swap area and finished the installation etc....Grub was install on the only drive there which is sda. After reboot, grub doesn't even come up.So it always boot in windows 8. I did repeat the installation process twice and yield same result. which is weird because this method always works for me so far.Even the laptop am using to write this post is a dual booting windows 7/ mint nadia installed the same way. Is there anything new in windows 8 that i didn't make provision for? Before starting the installation, all i read about was that , windows 8 should be installed first and ubuntu after. I went ahead and disable secure boot from the BIOS and enabled CSM (don't even know what it means) according to Acer custhelp site . I boot from USB and did fdisk -l bellow is the result: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

  • Brain Teaser: How Did I Do This (Part 1: The Solution)

    - by Geertjan
    In Part 1: The Challenge, published this time last week, I introduced a "brain teaser". The brain teaser asks you to figure out how to allow images and other files to be meaningfully dropped onto a NetBeans Platform application, i.e., on the drop something useful should happen with the dropped file: if the file is an image, the image should open in the IDE; if the file is a PDF document, the PDF viewer should open externally; if the file is a text file, it should open as a text in the IDE, etc. Solution. And here is the solution: http://bits.netbeans.org/dev/javadoc/org-openide-windows/org/openide/windows/ExternalDropHandler.html When an implementation of the "ExternalDropHandler" class is available in the global Lookup, and an object is being dragged over some part of the main window, the window system may call the methods of this class to decide whether it can accept or reject the drag operation. And when the object is actually dropped, this class will be asked to handle the drop. OK, so go ahead and implement the above class and put it into the Lookup. Or... guess what? The NetBeans Platform has a default implementation of the above class, appropriately named "DefaultExternalDropHandler". Not only is this useful to learn about how to implement the ExternalDropHandler class (i.e., by reading the source here): you can simply include the module that contains this class in your own NetBeans Platform application and then your application will be able to receive external drag/drop events and do something meaningful with them thanks to the DefaultExternalDropHandler. Do this: Open your NetBeans Platform application in NetBeans IDE. Right-click the application in the Projects window and choose Properties. In the Libraries tab, expand the "ide" cluster, and select "User Utilities". (That's where "DefaultExternalDropHandler.java" is found and registered in the Lookup.) Now click the "Resolve" button, if it appears, because some additional related modules need to now be included, if they haven't been included yet. Again in the "ide" cluster in the Libraries tab, select "Image". That's the Image Editor. Click OK. Run the application. Drag an image or some other type of file into your application, from outside the application, and you'll see the application tries to handle the drop. If the file being dragged is an image, it will open in the Image Editor, which you included in the previous step of these instructions. Hurray, you're done. Without any programming at all, you've added a cool new feature to your application.

  • why are my players drawn top the side of my viewport

    - by Jetbuster
    Following this admittedly brilliant and clean 2d camera class I have a camera on each player, and it works for multiplayer and i've divided the screen into two sections for split screen by giving each camera a viewport. However in the game it looks like this I'm not sure if thats their position relative to the screen or what The relevant gameScreen code, the makePlayers is setup so it could theoretically work for up to 4 players private void makePlayers() { int rowCount = 1; if (NumberOfPlayers > 2) rowCount = 2; players = new Player[NumberOfPlayers]; for (int i = 0; i < players.Length; i++) { int xSize = GameRef.Window.ClientBounds.Width / 2; int ySize = GameRef.Window.ClientBounds.Height / rowCount; int col = i % rowCount; int row = i / rowCount; int xPoint = 0 + xSize * row; int yPoint = 0 + ySize * col; Viewport viewport = new Viewport(xPoint, yPoint, xSize, ySize); Vector2 playerPosition = new Vector2(viewport.TitleSafeArea.X + viewport.TitleSafeArea.Width / 2, viewport.TitleSafeArea.Y + viewport.TitleSafeArea.Height / 2); players[i] = new Player(playerPosition, playerSprites[i], GameRef, viewport); } //players[1].Keyboard = true; } public override void Draw(GameTime gameTime) { base.Draw(gameTime); foreach (Player player in players) { GraphicsDevice.Viewport = player.PlayerCamera.ViewPort; GameRef.spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, SamplerState.PointClamp, null, null, null, player.PlayerCamera.Transform); map.Draw(GameRef.spriteBatch); // Draw the Player player.Draw(GameRef.spriteBatch); // Draw UI screen elements GraphicsDevice.Viewport = Viewport; ControlManager.Draw(GameRef.spriteBatch); GameRef.spriteBatch.End(); } } the player's initialize and draw methods are like so internal void Initialize() { this.score = 0; this.angle = (float)(Math.PI * 0 / 180);//Start sprite at it's default rotation int width = utils.scaleInt(picture.Width, imageScale); int height = utils.scaleInt(picture.Height, imageScale); this.hitBox = new HitBox(new Vector2(centerPos.X - width / 2, centerPos.Y - height / 2), width, height, Color.Black, game.Window.ClientBounds); playerCamera.Initialize(); } #region Methods public void Draw(SpriteBatch spriteBatch) { //Console.WriteLine("Hitbox: X({0}),Y({1})", hitBox.Points[0].X, hitBox.Points[0].Y); //Console.WriteLine("Image: X({0}),Y({1})", centerPos.X, centerPos.Y); Vector2 orgin = new Vector2(picture.Width / 2, picture.Height / 2); hitBox.Draw(spriteBatch); utils.DrawCrosshair(spriteBatch, Position, game.Window.ClientBounds, Color.Red); spriteBatch.Draw(picture, Position, null, Color.White, angle, orgin, imageScale, SpriteEffects.None, 0.1f); } as I said I think I'm gonna need to do something with the render position but I'm to entirely sure what or how it would be elegant to say the least

  • What actions does Ubuntu trigger when battery is low?

    - by blueyed
    When the battery is low, the screen gets dimmed after a few seconds already. This appears to be some special power-saving mode, and might be related to the time in org.gnome.settings-daemon.plugins.power.time-low (1200 seconds (20 minutes) the default). While this seems to get triggered by gnome-settings-daemon, I wonder what else Ubuntu does when this happens (e.g. via DBus listeners), or other event listeners that look for a "low battery" state. It seems like something in this regard causes Ubuntu / X / the system to behave more sluggish afterwards (when the laptop is on AC again), and I would like to look into what might be causing this. I could not find anything related via dconf-editor, e.g. in org.gnome.settings-daemon.plugins.power. It appears to get setup via idle_configure in plugins/power/gsd-power-manager.c, but it's probably something more related to something that listens on the DBus interface, which gets notified via e.g.: if (!g_dbus_connection_emit_signal (manager->priv->connection, NULL, GSD_POWER_DBUS_PATH, "org.freedesktop.DBus.Properties", "PropertiesChanged", props_changed, &error)) I could imagine that some "power saving" property gets set, but not unset when AC is available anymore and/or the battery is not low anymore. I have looked at the CPU governor setting (/sys/devices/system/cpu/cpu*/cpufreq/scaling_governor), but it was ondemand. I am using gnome-settings-daemon with awesomeWM on Ubuntu 14.04. gnome-settings-daemon=3.8.6.1-0ubuntu11.1 I've also compared gsd's plugins/power/gsd-power-manager.c with the one from Debian's gnome-settings-daemon-3.12.1, but could not find anything obvious that might have been fixed/changed in this regard. I have managed to trigger the gnome-power-manager's gnome-settings plugin (which dims the screen etc), by patching upower and use it after killing the system's upower daemon. (note that it's probably only energy that is being used by gpm to calculate it by itself). It does not make the system become sluggish.. OTOH I have not heard the speaker's beeping, which might come from the BIOS, which might be involved here, too - or other programs using the kernel's interface on /sys/class/power_supply/BAT0/. --- src/linux/up-device-supply.c.orig 2014-06-07 16:48:32.735920661 +0200 +++ src/linux/up-device-supply.c 2014-06-07 16:48:39.391920525 +0200 @@ -821,6 +821,9 @@ supply->priv->energy_old_first = 0; } + percentage = 3.1f; + time_to_empty = 3*60; + energy = 5; g_object_set (device, "energy", energy, "energy-full", energy_full,

  • Rendering Texture Quad to Screen or FBO (OpenGL ES)

    - by Usman.3D
    I need to render the texture on the iOS device's screen or a render-to-texture frame buffer object. But it does not show any texture. It's all black. (I am loading texture with image myself for testing purpose) //Load texture data UIImage *image=[UIImage imageNamed:@"textureImage.png"]; GLuint width = FRAME_WIDTH; GLuint height = FRAME_HEIGHT; //Create context void *imageData = malloc(height * width * 4); CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(imageData, width, height, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGColorSpaceRelease(colorSpace); //Prepare image CGContextClearRect(context, CGRectMake(0, 0, width, height)); CGContextDrawImage(context, CGRectMake(0, 0, width, height), image.CGImage); glGenTextures(1, &texture); glBindTexture(GL_TEXTURE_2D, texture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, imageData); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); Simple Texture Quad drawing code mentioned here //Bind Texture, Bind render-to-texture FBO and then draw the quad const float quadPositions[] = { 1.0, 1.0, 0.0, -1.0, 1.0, 0.0, -1.0, -1.0, 0.0, -1.0, -1.0, 0.0, 1.0, -1.0, 0.0, 1.0, 1.0, 0.0 }; const float quadTexcoords[] = { 1.0, 1.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 1.0, 1.0 }; // stop using VBO glBindBuffer(GL_ARRAY_BUFFER, 0); // setup buffer offsets glVertexAttribPointer(ATTRIB_VERTEX, 3, GL_FLOAT, GL_FALSE, 3*sizeof(float), quadPositions); glVertexAttribPointer(ATTRIB_TEXCOORD0, 2, GL_FLOAT, GL_FALSE, 2*sizeof(float), quadTexcoords); // ensure the proper arrays are enabled glEnableVertexAttribArray(ATTRIB_VERTEX); glEnableVertexAttribArray(ATTRIB_TEXCOORD0); //Bind Texture and render-to-texture FBO. glBindTexture(GL_TEXTURE_2D, GLid); //Actually wanted to render it to render-to-texture FBO, but now testing directly on default FBO. //glBindFramebuffer(GL_FRAMEBUFFER, textureFBO[pixelBuffernum]); // draw glDrawArrays(GL_TRIANGLES, 0, 2*3); What am I doing wrong in this code? P.S. I'm not familiar with shaders yet, so it is difficult for me to make use of them right now.

  • Interaction of a GUI-based App and Windows Service

    - by psubsee2003
    I am working on personal project that will be designed to help manage my media library, specifically recordings created by Windows Media Center. So I am going to have the following parts to this application: A Windows Service that monitors the recording folder. Once a new recording is completed that meets specific criteria, it will call several 3rd party CLI Applications to remove the commercials and re-encode the video into a more hard-drive friendly format. A controller GUI to be able to modify settings of the service, specifically add new shows to watch for, and to modify parameters for the CLI Applications A standalone (GUI-based) desktop application that can perform many of the same functions as the windows service, expect manually on specific files instead of automatically based on specific criteria. (It should be mentioned that I have limited experience with an application of this complexity, and I have absolutely zero experience with Windows Services) Since the 1st and 3rd bullet share similar functionality, my design plan is to pull the common functionality into a separate library shared by both parts applications, but these 2 components do not need to interact otherwise. The 2nd and 3rd bullets seem to share some common functionality, both will have a GUI, both will have to help define similar parameters (one to send to the service and the other to send directly to the CLI applications), so I can see some advantage to combining them into the same application. On the other hand, the standalone application (bullet #3) really does not need to interact with the service at all, except for possibly sharing a few common default parameters that can easily be put into an XML in a common location, so it seems to make more sense to just keep everything separate. The controller GUI (2nd bullet) is where I am stuck at the moment. Do I just roll this functionality (allow for user interaction with the service to update settings and criteria) into the standalone application? Or would it be a better design decision to keep them separate? Specifically, I'm worried about adding the complexity of communicating with the Windows Service to the standalone application when it doesn't need it. Is WCF the right approach to allow the controller GUI to interact with the Windows Service? Or is there a better alternative? At the moment, I don't envision a need for a significant amount of interaction, maybe just adding a new task once in a while and occasionally tweaking a parameter, but when something is changed, I do expect the windows service to immediately use the new settings.

  • Nails vs Screws (C# List vs Dictionary)

    - by MarkPearl
    General This may sound like a typical noob statement, but I’m finding out in a very real way that just because you have a solution to a problem, doesn’t necessarily mean it is the best solution. This was reiterated to me when a friend of mine suggested I look at using Dictionaries instead of Lists for a particular problem – he was right, I have always just assumed that because lists solved my problem I did not need to look elsewhere. So my new manifesto to counter this ageless problem is as follows… Look for a solution that will logically work Once you have a solution look for possible alternatives Decide why your current solution is the best approach compared to the alternatives If it is.. use it till something better comes along, if it isnt…. change What’s the difference between Lists & Dictionaries Both lists and dictionaries are used to store collections of data. Assume we had the following declarations… var dic = new Dictionary<string, long>(); var lst = new List<long>(); long data;   With a list, you simply add the item to the list and it will add the item to the end of the list. lst.Add(data); With a dictionary, you need to specify some sort of key and the data you want to add so that it can be uniquely identified. dic.Add(uniquekey, data);   Because with a dictionary you now have unique identifier, in the background they provide all sort’s of optimized algorithms to find your associated data. What this means is that if you are wanting to access your data it is a lot faster than a List. So when is it appropriate to use either class? For me, if I can guarantee that each item in my collection will have a unique identifier, then I will use Dictionaries instead of Lists as there is a considerable performance benefit when accessing each data item. If I cannot make this sort of guarantee, then by default I will use a list. I know this is all really basic, and I hope I haven’t missed some fundamental principle… If anyone would like to add their 2 cents, please feel free to do so…

  • Registering domain during Christmas holidays

    - by arkascha
    One of the domain names I tried to register previously has been blocked by a domain grabber two days prior to my own attempt. That was about 1 year ago. The attempt to buy the domain from that person failed due to a totally exaggerated price. So I dropped the issue and watched the domain (offered at sedo.com). As expected there were no more offers, the domain was not sold. Now I learn from the whois database that the registration of that domain name ends on 25 Dec 2012 (Christmas holiday). This raises two questions for me, I fail to find reliable answers on the internet. So maybe someone experienced here can drop a statement or a hint: Is it reasonable that the domain name in question really will be free again when that date mentioned in the whois database up to when the domain is registered has passed? I certainly know that the registration can be prolonged, that is not what I mean. I expect (hope) that that domain grabber does not extend the registration, since it costs money and effort and he failed to sell the domain. Provided this is the case and the domain registration is not prolonged, is that date mentioned reliable? Or might it just be some 'default' date? I would like to try to register that domain name as soon as it is unregistered. Since that domain grabber registered that domain only two days before my own registration attempt I would like to prevent such annoying interference next time. So I ask myself: is it possible to register a domain name on a holiday? I mean not to send an email to my provider to do so on that day or before, but to actually have to process taking place as not to wait for 1-2 days after the unregistration? My own provider which I am very happy with does not offer such service on a holiday (which is perfectly understandable). They are 'still checking' if they can offer something automatic. I researched and did not find an answer to the question if that is possible at all. Is an automatic registration attempt on a holiday possible? Where can I do that? Is that reliable?

  • Why are my scene's depth values not being written to my DepthStencilView?

    - by dotminic
    I'm rendering to a depth map in order to use it as a shader resource view, but when I sample the depth map in my shader, the red component has a value of 1 while all other channels have a value of 0. The Texture2D I use to create the DepthStencilView is bound with the D3D11_BIND_DEPTH_STENCIL | D3D11_BIND_SHADER_RESOURCE flags, the DepthStencilView has the DXGI_FORMAT_D32_FLOAT format, and the ShaderResourceView's format is D3D11_SRV_DIMENSION_TEXTURE2D. I'm setting the depth map render target, then i'm drawing my scene, and once that is done, I'm the back buffer render target and depth stencil are set on the output merger, and I'm using the depth map shader resource view as a texture in my shader, but the depth value in the red channel is constantly 1. I'm not getting any runtime errors from D3D, and no compile time warning or anything. I'm not sure what I'm missing here at all. I have the impression the depth value is always being set to 1. I have not set any depth/stencil states, and AFAICT depth writing is enabled by default. The geometry is being rendered correctly so I'm pretty sure depth writing is enabled. The device is created with the appropriate debug flags; #if defined(DEBUG) || defined(_DEBUG) deviceFlags |= D3D11_CREATE_DEVICE_DEBUG | D3D11_RLDO_DETAIL; #endif This is how I create my depth map. I've omitted error checking for the sake of brevity D3D11_TEXTURE2D_DESC td; td.Width = width; td.Height = height; td.MipLevels = 1; td.ArraySize = 1; td.Format = DXGI_FORMAT_R32_TYPELESS; td.SampleDesc.Count = 1; td.SampleDesc.Quality = 0; td.Usage = D3D11_USAGE_DEFAULT; td.BindFlags = D3D11_BIND_DEPTH_STENCIL | D3D11_BIND_SHADER_RESOURCE; td.CPUAccessFlags = 0; td.MiscFlags = 0; _device->CreateTexture2D(&texDesc, 0, &this->_depthMap); D3D11_DEPTH_STENCIL_VIEW_DESC dsvd; ZeroMemory(&dsvd, sizeof(dsvd)); dsvd.Format = DXGI_FORMAT_D32_FLOAT; dsvd.ViewDimension = D3D11_DSV_DIMENSION_TEXTURE2D; dsvd.Texture2D.MipSlice = 0; _device->CreateDepthStencilView(this->_depthMap, &dsvd, &this->_dmapDSV); D3D11_SHADER_RESOURCE_VIEW_DESC srvd; srvd.Format = DXGI_FORMAT_R32_FLOAT; srvd.ViewDimension = D3D11_SRV_DIMENSION_TEXTURE2D; srvd.Texture2D.MipLevels = texDesc.MipLevels; srvd.Texture2D.MostDetailedMip = 0; _device->CreateShaderResourceView(this->_depthMap, &srvd, &this->_dmapSRV);

  • In-Store Tracking Gets a Little Harder

    - by David Dorf
    Remember how Nordstrom was tracking shopper movements within their stores using the unique number, called a MAC, emitted by the WiFi radio in smartphones?  The phones didn't need to connect to the network, only have their WiFi enabled, as most people do by default.  They did this, presumably, to track shoppers' path to purchase and better understand traffic patterns.  Although there were signs explaining this at the entrances, people didn't like the notion of being tracked.  (Nevermind that there are cameras in the ceiling watching them.)  Nordstrom stopped the program. To address this concern the Future of Privacy, a Washington think tank, created Smart Store Privacy, a do-not-track service that allows consumers to register their MAC address in much the same way people register their phone numbers in the national do-not-call list.  A group of companies agreed to respect consumers' wishes and ignore smartphones listed in the database.  The database includes Bluetooth identifiers as well.  Of course you could simply turn your bluetooth and WiFi off when shopping as well. Most know that Apple prefers to use BLE beacons to contact and track smartphones within their stores.  This feature extends the typical online experience to also work in physical stores.  By identifying themselves, shoppers can expect a more tailored shopping experience much like what we've come to expect from Amazon's website, with product recommendations and offers that are (usually) relevant. But the upcoming release of iOS8 is purported to have a new feature that randomizes the WiFi MAC address of smartphones during the "probing" phase.  That is, before connecting to the WiFi network, a random MAC number is used so as to keep the smartphone's real MAC address secret.  Unless you actually connect to the store's WiFi, they won't recognize the MAC address. The details on this are still sketchy, but if the random MAC is consistent for a short period, retailers will still be able to track movements anonymously, but they won't recognize repeat visitors.  That may be sufficient for traffic analytics, but it will stymie target marketing.  In the case of marketing, using iBeacons with opt-in permission from consumers will be the way forward. There is always a battle between utility and privacy, so I expect many more changes in this area.  Incidentally, if you'd like to see where beacons are being used this site tracks them around the world.

  • Ubuntu 12.4.1 failing in vm both Vbox and Vmware on new HP Envy 4t-1000

    - by Chas
    Brand new to Linux, getting frustrated trying to get an environment up with Ubuntu. My primary goal is to learn Linux and Apache/PHP development. I need to keep my Windows OS as main on my machine for work, so i'm trying to virtualize Ubuntu 12.4.1 without luck (many attempts). I have a new HP Envy 4t-1000 with 16gb ram, and 32 gb ssd caching with 500gb spindle hard drive. Graphics card is an Intel HD 3000 with AMD Radeon 7670M. With installing Ubuntu desktop in VBox, I'm getting this result: https://forums.virtualbox.org/viewtopic.php?f=6&t=51939 With VMware workstation 7 (patched), I complete the install of Ubuntu, it reboots, purple desktop briefly flashes then it drops to command line. I bought a beginning Ubuntu book, and it recommends trying to manually configure graphics if this happens. So I tried doing a safe boot holding shift - I get to the first screen (GRUB) loads fine, and I choose recovery mode. After choosing the recovery mode, I get the recovery mode options, and can arrow down to what the book suggests 'Run in fail safe graphic mode.' Once I select this option, I get a black screen with a large white dialogue box, at the top it says "The system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself." Then there is an ok button way down at the bottom. When I select 'ok' I get a menu for a few options, book recommended 'reconfigure graphics.' When I try this, I get a menu of two options: 1) "Use generic (default) configuration or 2) use backup. I've tried both options several times, hitting ok just refreshes screen and nothing more. Rebooting at this point just goes back to command line as before. I don't know what to do at this point, I've spent too many hours this weekend trying in both VBox and VMware to get Ubuntu going. Isn't there like a very basic graphic display or something I can use to at least get into the desktop? I explored the GRUB some more, and tried to look at the startup and xserver logs - both are blank. No help there I guess? When I try to choose 'Edit the configuration file, then 'ok' screen just refreshes on same menu options, nothing happens. thx for any advice. I really need to focus on learning Linux, Apache and PHP, so perhaps Ubuntu just won't work on my hardware? Any other suggestions? I will need to virtualize - THANKS for any help/advice.

  • 3 Monitors, Ubuntu 12.04, Gnome 3, 2 nvidia cards, WITH xrandr or xinerama?

    - by Josh
    Ok. I have been banging my head against the wall for over a week now trying to get 3 monitors to work. I have: 1 - Nvidia 8600 GT 512MB PCIEx16 1 - Nvidia GT 240 1GB PCIEx16 They are not running in SLI (obviously). I have tried to use everything from tutorials to a few templates, all the way up to nvidia-settings, etc etc etc.. From what I hear, Xinerama doesnt like gnome 3 because of the compositing, although I have read a lot about using Xrandr instead, and getting the compositing working, but alas, I cannot. It always either crashes X and I have to replace the xorg.conf with my backup, or it defaults to the gnome-classic desktop, and on top of that, when it does default, it keeps adding more and more panels. Basically, I want to be able to use all 3 monitors (yes, just like in windows) to drag and drop from different windows. I have xorg-edit, but I am still not too sure on how to set this up? Is there any way to: A Get compositing working with 3 monitors, 2 nvidia cards, xinerama, and gnome 3? or BUse twinview with 3 monitors (I have heard it can be done by manually editing xorg.conf) or CSet up Xrandr to draw all 3 monitors with compositing. or DUse separate X for each monitor, and be able to use gnome with compositing, as well as drag between all 3 or EANYTHING. lol. I just want this to work. Any help you can provide would be greatly appreciated. BTW, I am running an ubuntu mini install with gnome. Everything works great but this. I can run it fine with 2 monitors and compositing, but not with 3. Also, what is the best GUI tool for editing xorg.conf? Im not finding anything that is up to date at all, and also is understandable by humans. haha. Im actually an engineer by trade, and have been working with computers a LONG time, but this xorg.conf stuff is really confusing the crap out of me. lol Thanks!

  • Using all Ten IO slots on a 7420

    - by user12620172
    So I had the opportunity recently to actually use up all ten slots in a clustered 7420 system. This actually uses 20 slots, or 22 if you count the clusteron card. I thought it was interesting enough to share here. This is at one of my clients here in southern California. You can see the picture below. We have four SAS HBAs instead of the usual two. This is becuase we wanted to split up the back-end taffic for different workloads. We have a set of disk trays coming from two SAS cards for nothing but Exadata backups. Then, we have a different set of disk trays coming off of the other two SAS cards for non-Exadata workloads, such as regular user file storage. We have 2 Infiniband cards which allow us to do a full mesh directly into the back of the nearby, production Exadata, specifically for fast backups and restores over IB. You can see a 3rd IB card here, which is going to be connected to a non-production Exadata for slower backups and restores from it.The 10Gig card is for client connectivity, allowing other, non-Exadata Oracle databases to make use of the many snapshots and clones that can now be created using the RMAN copies from the original production database coming off the Exadata. This allows for a good number of test and development Oracle databases to use these clones without effecting performance of the Exadata at all.We also have a couple FC HBAs, both for NDMP backups to an Oracle/StorageTek tape library and also for FC clients to come in and use some storage on the 7420.  Now, if you are adding more cards to your 7420, be aware of which cards you can place in which slots. See the bottom graphic just below the photo.  Note that the slots are numbered 0-4 for the first 5 cards, then the "C" slots which is the dedicated Cluster card (called the Clustron), and then another 5 slots numbered 5-9. Some rules for the slots: Slots 1 & 8 are automatically populated with the two default SAS cards. The only other slots you can add SAS cards to are 2 & 7. Slots 0 and 9 can only hold FC cards. Nothing else. So if you have four SAS cards, you are now down to only four more slots for your 10Gig and IB cards. Be sure not to waste one of these slots on a FC card, which can go into 0 or 9, instead.  If at all possible, slots should be populated in this order: 9, 0, 7, 2, 6, 3, 5, 4

  • How can I cleanly and elegantly handle data and dependancies between classes

    - by Neophyte
    I'm working on 2d topdown game in SFML 2, and need to find an elegant way in which everything will work and fit together. Allow me to explain. I have a number of classes that inherit from an abstract base that provides a draw method and an update method to all the classes. In the game loop, I call update and then draw on each class, I imagine this is a pretty common approach. I have classes for tiles, collisions, the player and a resource manager that contains all the tiles/images/textures. Due to the way input works in SFML I decided to have each class handle input (if required) in its update call. Up until now I have been passing in dependencies as needed, for example, in the player class when a movement key is pressed, I call a method on the collision class to check if the position the player wants to move to will be a collision, and only move the player if there is no collision. This works fine for the most part, but I believe it can be done better, I'm just not sure how. I now have more complex things I need to implement, eg: a player is able to walk up to an object on the ground, press a key to pick it up/loot it and it will then show up in inventory. This means that a few things need to happen: Check if the player is in range of a lootable item on keypress, else do not proceed. Find the item. Update the sprite texture on the item from its default texture to a "looted" texture. Update the collision for the item: it might have changed shape or been removed completely. Inventory needs to be updated with the added item. How do I make everything communicate? With my current system I will end up with my classes going out of scope, and method calls to each other all over the place. I could tie up all the classes in one big manager and give each one a reference to the parent manager class, but this seems only slightly better. Any help/advice would be greatly appreciated! If anything is unclear, I'm happy to expand on things.

  • Melhoria de Performance no .NET 4.5: Multicore Just-in-Time (JIT).

    - by anobre
    Olá pessoal! Dando uma lida nas melhorias de performance da plataforma .NET 4.5, me deparei com algo extremamente interessante: Multicore Just-in-Time (JIT). A teoria é muito simples: por que não utilizar vários núcleos para a compilação JIT? Além disto, será que seria possível compilar os métodos em uma determinada ordem, onde os primeiros fossem aqueles com maior probabilidade de execução? Isto parece meio loucura mas é o que o Multicore Just-in-Time (JIT) faz. E o melhor de tudo, de uma forma extremamente simples. As aplicações ASP.NET 4.5 já o fazem por default. Em outras ocasiões, basta executar duas linhas de código: uma indicando a pasta onde o arquivo que armazenará o profile ficará, e a outra para iniciar o procedimento. Este profile é o arquivo responsável por armazenar a ordem de compilação dos métodos, para que aqueles com maior chance de serem executados mais cedo sejam compilados antes. Código para este processo: ProfileOptimization.SetProfileRoot(@"C:\ProfileRoot"); ProfileOptimization.StartProfile("profile"); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Esta otimização na compilação só será notada após a criação do profile. Portanto, na primeira vez nada será percebido. Ao final do processo, um arquivo com o nome escolhido (no caso profile) será criado, na pasta indicada como root: Fica a dica! Abraços!
