  • Laptop drains of quickly with battery

    - by Shyam
    I am a user since years in ubuntu and I have not come across this problem with ubuntu till date. My battery drains off immediately after I unplug my AC power. The options I tried: 1) checked the battery state with : cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charged present rate: 0 mA remaining capacity: 392 mAh present voltage: 12476 mV Initially it was showing charging state: charging after 5mins it started displaying as charged. ! Based on that if I remove my AC Power it shows low battery notification. 2) When I run acpi : acpi -b Battery 0: Unknown, 9% The battery state shows as unknown. But initially when we plug-in to AC adapter acpi -b Battery 0: Charging, 9%, 13:04:00 until charged 3) When the check the same with : upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:02/PNP0C09:00/PNP0C0A:00/power_supply/BAT0 vendor: HP power supply: yes updated: Thu Nov 1 16:06:40 2012 (20 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 4.2336 Wh energy-empty: 0 Wh energy-full: 33.1128 Wh energy-full-design: 33.1128 Wh energy-rate: 5.6052 W voltage: 12.474 V time to full: 5.2 hours percentage: 12.7854% capacity: 100% technology: lithium-ion Is the power stats output, It says 5hrs to charge completely, If I charge it even more than 5hrs and unplug the AC power, It again cribs stating LOW BATTERY !! The same thing does not happen with Windows7. Any suggestions/ help will be greatly appreciated.

  • How can I move a polygon edge 1 unit away from the center?

    - by Stephen
    Let's say I have a polygon class that is represented by a list of vector classes as vertices, like so: var Vector = function(x, y) { this.x = x; this.y = y; }, Polygon = function(vectors) { this.vertices = vectors; }; Now I make a polygon (in this case, a square) like so: var poly = new Polygon([ new Vector(2, 2), new Vector(5, 2), new Vector(5, 5), new Vector(2, 5) ]); So, the top edge would be [poly.vertices[0], poly.vertices[1]]. I need to stretch this polygon by moving each edge away from the center of the polygon by one unit, along that edge's normal. The following example shows the first edge, the top, moved one unit up: The final polygon should look like this new one: var finalPoly = new Polygon([ new Vector(1, 1), new Vector(6, 1), new Vector(6, 6), new Vector(1, 6) ]); It is important that I iterate, moving one edge at a time, because I will be doing some collision tests after moving each edge. Here is what I tried so far (simplified for clarity), which fails triumphantly: for(var i = 0; i < vertices.length; i++) { var a = vertices[i], b = vertices[i + 1] || vertices[0]; // in case of final vertex var ax = a.x, ay = a.y, bx = b.x, by = b.y; // get some new perpendicular vectors var a2 = new Vector(-ay, ax), b2 = new Vector(-by, bx); // make into unit vectors a2.convertToUnitVector(); b2.convertToUnitVector(); // add the new vectors to the original ones a.add(a2); b.add(b2); // the rest of the code, collision tests, etc. } This makes my polygon start slowly rotating and sliding to the left, instead of what I need. Finally, the example shows a square, but the polygons in question could be anything. They will always be convex, and always with vertices in clockwise order.

  • Confused about application submission

    - by snowflake
    I finished my app but I'm totally confused about how to submit it to launchpad and the software center. I'm also new to launchpad. 1) I created a project at launchpad and synchronized an OpenPGP key via the password tool. This was about 30 minutes ago but launchpad still shows "No OpenPGP keys registered." Is this normal? 2) What I have to do next with the PPA? 3) How do I submit my app? Do I have to adjust files with the PPA? The showdown blog shows that quickly submitubuntu is enough but here in the forum I read about quickly release or quickly share. So which one is correct? 4) Do I have to add this file to launchpad as well? 5) Do I get a confirmation that my app was correctly submitted and take part of the contest? Since I do it for first time I want to be sure that everything is ok. I'm sorry for all my questions and I know that there are many topics about it but everywhere something different is written and I'm confused how to proceed. Thanks in advance!

  • Xencenter guest will not boot

    - by Georgi
    I have xen server free edition. Today one of the guest VM was very loaded and I decided to reboot it. Now it can not start. It is with Ubuntu 10.04 Server. The machine is shown as running in xsconsole and in windows Xen control center. It shows 100 % CPU and 100 % RAM usage. The console shows nothing (it doesn't show boot process). And the worst is that I have no backup. Is there any advice how to see what is going on. I exported it to file and now I am trying it to import it into another server, because I can't reboot the physical server it runs on. Can this save me (the reboot of the server) Thank you

  • My profile won't load!

    - by blsub6
    I can get into my Windows Server 2008 R2 primary domain controller via remote desktop just fine. It's my boss who's got his profile messed up. When he tries to log in, he gets the message The User Profile service failed the logon. User profile cannot be loaded. I've looked for his profile everywhere and cannot find it to delete or fix it. System Properties Advanced User Profiles shows my profile, the Administrator profile and the Default Profile. HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList only shows my profile and the Administrator profile. Everything that I've found on the internets points me to those locations. Help a brotha out?

  • How to play an MKV 3D side-by-side video?

    - by djechelon
    I have a video in Matroska format (MKV, file extension .mkv), 3D half-SBS, where the 1280x720 frame shows the left-eye frame on the left and the right-eye frame on the right. I don't have a 3DTV, but I have NVidia 3D Vision: I tried to open it with PowerDVD 10 with no result (program hangs). With the same PowerDVD, I tried to play the Avatar 3D trailer downloaded from YouTube (MP4 format), but it now shows it the two frames. PowerDVD 10 is advertised to support 3D and 3D Vision. Why can't I play these videos? NVidia Stereoscopic player plays the Avatar trailer fine, but it doesn't support MKV.

  • Problems with vim/locale as non-root user on Solaris

    - by Lyle
    I do some work on a Solaris 10 machine, and my .vimrc is set up to show unicode characters for tabs and line endings: set listchars=tab:?\ ,eol:¬ This works out of the box on my OS X machine. On Linux as well as Solaris I get the following error when I start vim: Error detected while processing /home/lhanson/.vimrc: line 17: E474: Invalid argument: listchars=tab:?~V?\ ,eol:¬ I solved this on my Linux box by setting LANG=en_US.utf8 ('locale -a' shows this as being an option). On Solaris, however, 'locale -a' shows the following: C POSIX iso_8859_1 Setting LANG to C or POSIX yields the same error, and even though iso_8859_1 probably wouldn't work it doesn't successfully change the locale anyway. As a non-root user, is there any way I can have my unicode characters show up?

  • Gnome 3 - Multiple Video Cards - Xinerama -- Forced Fallback Mode

    - by Alvin
    Just installed a 2nd nvidia video card -- previously had gnome 3 working perfectly with 2 monitors on a a single video card using twinview tried a number of things thus far twinview on 1 card + xinerama no xinerama no twinview various manual xorg.conf hacks based on random forums (couple references below) xinerama no twinview with and without Extensions Composite The last one is what I'm using now -- it results in a forced fallback mode with Composite Disable set at the end of xorg.conf via nvidia-settings Section "Extensions" Option "Composite" "Disable" EndSection when I disabled that last snippet it boots to gnome 3 full with the left monitor on a black screen and the middle monitor as primary but non-responsive switching to console mode Ctrl+Alt+F1 and then switching back I get 3 black screens with a mouse that can move around but nothing to interact with issue seems related to OpenGL and the multiple video cards -- I can boot into Unity without issue though my Glx-Dock shows up with the black background as barely shows in the screenshot below indicating the OpenGL is not initiated has anyone had any luck with getting Xinerama to work with Multiple NVidia Video Cards with OpenGL support? Found this in the logs while looking a bit further [ 23.208] (II) NVIDIA(1): Setting mode "nvidia-auto-select+0+0" [ 23.254] (WW) NVIDIA(1): The GPU driving screen 1 is incompatible with the rest of the [ 23.254] (WW) NVIDIA(1): GPUs composing the desktop.

  • Finding source of leaking active memory on Mac OS Lion

    - by Tim Kemp
    My activity monitor shows 6GB of active RAM usage: Yet my Real Memory column shows nothing like that amount: (There's another screenful below that, all smaller.) Backing that up, the output from this command (which sums up memory usage of every running process): ps -axm -o "rss,comm" | awk 'BEGIN { s=0;}; {s=s+$1;}; END { printf("%.2f GB\n", (s/1024.0/1024));}' Gives 4.09GB, so it looks to me like 2GB has leaked. I see much wider ranges sometimes, perhaps 2 or 3GB from the ps command and as much as 7 or 8GB of Active usage reported by Activity Monitor. I've tried quitting everything and logging my user out and back in again, but the Active usage is still far higher than the RAM reported by ps and by each process to Activity Monitor. This 2GB of active RAM is basically unrecoverable unless I reboot. Is there any way to a) detect what's leaking and b) get it back? Thanks

  • Nokia Pc Suite problems with bluetooth (win7)

    - by wurlog
    I have a new Nokia C5-00 and a HP 620. The Bluetoothdriver are installed and the windows Bluetoothstack finds the mobile. After installing Nokia PC Suite I am asked to choose a connection method. As I click on Bluetooth the Nokia PC Suite shows an error message: "Cannot use the connection type.Check that all the needd hardware,software and drivers are available. (Code: OpenMedia)" I tried to switch it on and off via the "wireless" key on the laptop. The HP Software for the button shows that the Bluetooth is deactivated and advices me to go to the device manager and activate the Bluetooth device. Strangely the Bluetooth symbol (I guess from the windows Bluetoothstack) pops up at the same time and I can use the Bluetooth in it's basic windows features, but still nokia suite won't work. ideas????

    i had been using bluetooth fine, with devices working, but today when i turned on my computer again bluetooth strangely failed. there is a bluetooth icon on the top bar, showing "bluetooth on", but if i click on the "bluetooth settings" item, a system settings window shows up and shows me a bluetooth on-off switch which is disabled (i.e. fixed to off). more information about my case: i am a new linux used, coming from windows, and do not know supposedly-obvious commands. i am using a laptop. it initially doesn't have bluetooth. i bought a built-in type (instead of USB type) bluetooth module, and added it inside the laptop. hence, i do not have a specific FN+* key for bluetooth. in windows, i needed to install an additional driver that was intended for other machines in my laptop's seires which have built-in (i.e. factoryly built-in)j bluetooth modules. the Fn+* key seemed to only affect wifi under ubuntu. i have been successfully using magicmouse with my later-added built-in bluetooth module/adapter on both windows and ubuntu i have been trying to tweak the magicmouse scrolling speed with commands rmmod something, modprobe hid_magicmouse --scroll_speed=45 --scroll_acceleration=30 or something, then added a file `/etc/modprobe.d/magicmouse.conf". the mouse seemed to be working fine with these changes. now if i run commands like hcitool dev, the shell tells me that i do not have any "Devices" or "adapters". i seem to have bluez installed, because when i type "blue" then tab-autocomplete, a bunch of commands like bluez-test-device pops up. -- update -- some commands and their results: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool dev Devices: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool scan Device is not available: No such device easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: no Hard blocked: no easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: yes Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no

  • Is my disk hot or not?

    - by adriangrigore
    I am trying to figure out the temperature of my dedicated server's harddisk. For this purpose, I've downloaded HDTune to monitor the S.M.A.R.T. Status. The problem is that the current temperature for "C2 Temperature" is 73 degrees celsius, but the little thermometer on top of the window shows 27 degrees celsius. See this screenshot: http://screencast.com/t/OGJhZGIxND Another monitoring software (Anfibia Reactor) shows similar behavior: Disk temperature is around 30 degrees, but it says that the disk is too hot. So, is my disk hot or not? Since this is a dedicated server, I can't just open the case and put a thumb on it.

  • Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML - Part One

    - by Janice J. Heiss
    A new article, the first of two parts, now up on otn/java by Oracle Evangelist and JavaFX expert, James L. Weaver, titled “Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML, Part One,” shows developers how to leverage the power of the FX Markup Language (FXML) to define the UI in enterprise applications.As Weaver explains, “JavaFX 2.0 is an API and runtime for creating Rich Internet Applications (RIAs). JavaFX was introduced in 2007, and version 2.0 was released in October 2011. One of the advantages of JavaFX 2.0 is that the code can be written in the Java language using mature and familiar tools.”He goes on to show how to use the potential of FX Markup Language, which comes with JavaFX 2.0, to efficiently define the user interface for enterprise applications. FXML functions to enable the expression of the UI using XML. “Classes that contain FXML functionality are located in the javafx.fxml package,” says Weaver, “and they include FXMLLoader, JavaFXBuilderFactory, and an interface named Initializable.” Weaver’s article offers a sample application that shows how to use the capabilities of FXML and JavaFX 2.0 to create an enterprise app. Have a look at the article here.

  • Rotate around the centre of the screen

    - by Dan Scott
    I want my camera to rotate around the centre of screen and I'm not sure how to achieve that. I have a rotation in the camera but I'm not sure what its rotating around. (I think it might be rotating around the position.X of camera, not sure) If you look at these two images: http://imgur.com/E9qoAM7,5qzyhGD#0 http://imgur.com/E9qoAM7,5qzyhGD#1 The first one shows how the camera is normally, and the second shows how I want the level to look when I would rotate the camera 90 degrees left or right. My camera: public class Camera { private Matrix transform; public Matrix Transform { get { return transform; } } private Vector2 position; public Vector2 Position { get { return position; } set { position = value; } } private float rotation; public float Rotation { get { return rotation; } set { rotation = value; } } private Viewport viewPort; public Camera(Viewport newView) { viewPort = newView; } public void Update(Player player) { position.X = player.PlayerPos.X + (player.PlayerRect.Width / 2) - viewPort.Width / 4; if (position.X < 0) position.X = 0; transform = Matrix.CreateTranslation(new Vector3(-position, 0)) * Matrix.CreateRotationZ(Rotation); if (Keyboard.GetState().IsKeyDown(Keys.D)) { rotation += 0.01f; } if (Keyboard.GetState().IsKeyDown(Keys.A)) { rotation -= 0.01f; } } } (I'm assuming you would need to rotate around the centre of the screen to achieve this)

  • Toshiba monitor not displaying anything

    - by MirroredFate
    Alright, so I agreed to fix a friends computer, thinking it was a software problem, not hardware. I was going to use an XP disc and valid code to swap her from Vista to XP, as apparently Vista had some driver issues. I found out, however, that the real problem was her heat sink was completely clogged, causing the computer to overheat and shut down. So, I took the computer apart and cleaned the heat sink. However, after putting it all back together, and turning it on, nothing at all shows up. I plugged in an external monitor, and nothing shows up on that either. I have double, triple, decuply checked all the connections and everything appears to be plugged in, attached, and in the right place. I am out of ideas. So, my question is, does anyone have any clue what is going on, and have suggestions I could try?

  • Four Proven Advantages of Online Learning | Outside Cost, Accessibility or Flexibility

    - by Mohit Phogat
    Coursera believes that online courses complement and supplement traditional education (versus a common misconception online will “replace” traditional.) Our research shows that Coursera’s platform, when used concurrently with a traditional classroom setup, is ideal for “blended learning” (i.e., students watch lectures pre-class, then class-time focuses on interactive work and discussion.) Additionally, we agree with Brad Zomick of SkilledUp—an online learning aggregator—who acknowledges an online course “isn’t an alternative at all but rather a different path with its own rewards.” The advantages of Coursera and our apps for mobile were straightforward and conspicuous from the start: we’re free, open, and flexible to learners’ unique needs and style. Over the past two years, however, the evidence proves there are many more tangible benefits to open, online learning. In SkilledUp’s “The Advantages of Online Courses [Infographic]”–crafted from findings of leading educational research–four observations stand out from the overt characteristics: Speedier Learning - “Research shows that online students achieve same or better learning results in about half the time as those in traditional courses” More Active, Engaged & Motivated - Learners thrive “when working with coursework that is challenging but within their capacity to master.” Tangible Skill Building - with an “improved attitude toward learning” Better Teaching Quality - Courses are taught by experts, with various multimedia and cutting-edge technology, and “are usually better organized than traditional courses” This is only the beginning, Courserians! Everyday we hear your incredible stories on how open online courses enrich your lives and enhance your careers. Meanwhile we study the steady stream of scientific, big-data research proving their worth on a large-scale (such as UPenn’s latest research on the welcomed diversity in Coursera-hosted Wharton MBA courses.) Our motto “Learning without Limits” reminds us that open, online courses give tremendous opportunity to those that might not otherwise have access (or time, or money) to study at a high-caliber institution.

  • Why does my system use so much cache?

    - by Dave M G
    Previously, on my desktop computer running Ubuntu 14.04, I had 4GB RAM, which I thought should be plenty. However, after being on for a while, my computer would seem to get slow. I have a system resource monitor app in my Gnome panel, which I assume represents the available RAM (?). It shows a dark green area as being "Memory", and a light green area as "Cache". The "Cache" would slowly grow until it filled the whole graph, and then programs would get slow to load, or it would take a while to switch programs. I could alleviate the problem somewhat with this command, but eventually the computer cache fills up again, so it's only a bandaid: sudo sh -c "sync; echo 3 > /proc/sys/vm/drop_caches" So, I figured I'd get more RAM, so I replaced one 2GB stick with an 8GB stick, and now I have 10 GB ram. And my "cache" still slowly maxes out and my computer slows as a result. Also, sometimes the computer starts out with "cache" maxed when I first boot and log in. Not always though, I don't know if there's a pattern that determines why it happens. Why is Ubuntu using up so much cache? Is 10GB not enough for Ubuntu? Here's what my system monitor looks like in my Gnome panel. The middle square shows RAM usage. The light green area is the "cache": This is my memory and swap history, which doesn't seem to include any information about "cache". I realize at this point I'm not totally clear on the difference between "cache" and "swap":

  • How to diagnose network speed drops

    - by Luis Alvarado
    Here is the image of System Monitor first: The graph shows the cycle the connection goes through. After 10 to 15 seconds it drops to 0 KB/S, then goes up to the Max speed (120 KB/S) then it repeats. dmesg shows the following during that time: [ 6066.757211] wlan0: send auth to 00:26:5a:b5:05:7b (try 1/3) [ 6066.804405] wlan0: authenticated [ 6066.804578] rt2800pci 0000:02:01.0 wlan0: disabling HT/VHT due to WEP/TKIP use [ 6066.805016] wlan0: associate with 00:26:5a:b5:05:7b (try 1/3) [ 6066.809218] wlan0: RX AssocResp from 00:26:5a:b5:05:7b (capab=0x431 status=0 aid=1) [ 6066.809581] wlan0: associated [ 6066.810203] bridge-eth0: disabling the bridge on dev down [ 6066.810239] bridge-eth0: down [ 6066.810254] bridge-eth0: detached [ 6066.810309] /dev/vmnet: open called by PID 1679 (vmnet-bridge) [ 6066.810322] /dev/vmnet: hub 0 does not exist, allocating memory.
