  • 12.0.4.3 - Missing Battery Icon, auto Suspend not working, Keyboard shortcuts volume up/down no longer working

    - by Navraj
    Problems I am experiencing: Battery Icon not showing up unity bar (top right corner). Volume Up/Down/Mute not working. Bluetooth hot keys described above also not working.Brightness up/down keys on this keyboard no longer working (apple wireless keyboard) Laptop no longer suspends when lid is shut. I have to go to 'power' button on top right corner and click on 'Suspend' All was working flawlessly until I did the following: I have recently upgraded to Nvidia propriety driver version 319 {version recommended}. Installed Xscreensaver and then removed it and went back to default screensaver. Done a system update (1st since installing) and now currently running: Linux 3.8.0-32-generic #47~precise1-Ubuntu SMP Wed Oct 2 16:19:35 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux NOTE: Base system was ubuntu 12.04.3 installed from ISO however lsb_release reports "No LSB modules are available" 4.installed psensor. I have check power setting (via Settings) and power setting via dconf-editor and set to recommended settings as described in posts detailing solution to this problem. - I have disabled 1) Nvdia settings at startup and 2) psensor at startup but this does not help. I am using an HP DV7 with 2GB Nvidia card. Not using any fancy graphics features. Recommendations? Thanks.

  • How to approach scrum task burn down when tasks have multiple peoples involvement?

    - by AgileMan
    In my company, a single task can never be completed by one individual. There is going to be a separate person to QA and Code Review each task. What this means is that each individual will give their estimates, per task, as to how much time it will take to complete. The problem is, how should I approach burn down? If I aggregate the hours together, assume the following estimate: 10 hrs - Dev time 4 hrs - QA 4 hrs - Code Review. Task Estimate = 18hrs At the end of each day I ask that the task be updated with "how much time is left until it is done". However, each person generally just thinks about their part of it. Should they mark the effort remaining, and then ADD the effort estimates to that? How are you guys doing this? UPDATE To help clarify a few things, at my organization each Task within a story requires 3 people. Someone to develop the task. (do unit tests, ect...) A QA specialist to review task (they primarily do integration and regression tests) A Tech lead to do code review. I don't think there is a wrong way or a right way, but this is our way ... and that won't be changing. We work as a team to complete even the smallest level of a story whenever possible. You cannot actually test if something works until it is dev complete, and you cannot review the quality of the code either ... so the best you can do is split things up into small logical slices so that the bare minimum functionality can be tested and reviewed as early into the process as possible. My question to those that work this way would be how to burn down a "task" when they are setup this way. Unless a Task has it's own sub-tasks (which JIRA doesn't allow) ... I'm not sure the best way to accomplish tracking "what's left" on a daily basis.

  • Better way to go up/down slope based on yaw?

    - by CyanPrime
    Alright, so I got a bit of movement code and I'm thinking I'm going to need to manually input when to go up/down a slope. All I got to work with is the slope's normal, and vector, and My current and previous position, and my yaw. Is there a better way to rotate whether I go up or down the slope based on my yaw? Vector3f move = new Vector3f(0,0,0); move.x = (float)-Math.toDegrees(Math.cos(Math.toRadians(yaw))); move.z = (float)-Math.toDegrees(Math.sin(Math.toRadians(yaw))); move.normalise(); if(move.z < 0 && slopeNormal.z > 0 || move.z > 0 && slopeNormal.z < 0){ if(move.x < 0 && slopeNormal.x > 0 || move.x > 0 && slopeNormal.x < 0){ move.y += slopeVec.y; } } if(move.z > 0 && slopeNormal.z > 0 || move.z < 0 && slopeNormal.z < 0){ if(move.x > 0 && slopeNormal.x > 0 || move.x < 0 && slopeNormal.x < 0){ move.y -= slopeVec.y; } } move.scale(movementSpeed * delta); Vector3f.add(pos, move, pos);

  • Finding back to an old project that was turned upside-down by the developer. Your workflow?

    - by Kreativrandale
    after some time I'm asked to work on a heavy web-project I did (layout, html/css) about a year ago. There are some changes that have to be made, basically some css and js stuff. By now the whole project was turned upside down by the developer. It gives me a hard time to connect to the work of him, especially because my old files and file-structure won't work anymore. Thats why I need a up-to-date working-environment, but I don't want to change the files on the server directly. Need some testing and improving while doing this. So, what is your workflow in such a case? Thought about copying the whole/parts of the server to a own homeserver. But even that will be a big task for me (I'm more the front-end-guy). Would be great if theres a way to shrink it down (php, mysql,...), since I only need to change some css/html javascript. Are there any tools available? Love to hear how you handle such situations. Thanks a lot!

  • Bridging 10GbE with 12.04 - bridging works but the bridging computer has no internet access

    - by Donal
    I have been trying to get 12.04 bridging working with two 10GbE cards. I have 2 10GbE cards in a linux box being used only for this bridge, 1 with 2 10GbaseT ports and another with a single CX4 port. I have 2 client computers connected with 10GbaseT cards and the CX4 card connects to a procurve switch. I can get the bridging happening mostly the way that I want, The clients receive dhcp information from the dhcp server (not the bridging machine) and can connect to and properly see the rest of the network. Speeds are ok, not amazing but working on that is another matter. My problem is that the bridging machine has no internet access ... meaning I can't update anything or apt-get anything It can ping all other machines on the local network. I've tried the helpful hints from: https://help.ubuntu.com/community/NetworkConnectionBridge "Enabling Internet Use on the Bridging Computer" and get the following RTNETLINK answers: File exists but dhclient br0 does nothing for me :( I think if it is anything it a multiple route problem as both br0 and eth4 have ipaddresses ... even though I have only set it up so that br0 has one ...

  • Is there any way to lock down Photoshop to prevent designers from creating styles that cannot be rendered in CSS?

    - by Hugo Rodger-Brown
    Photoshop is a much more powerful design tool than CSS, and given free reign to design at will, designers will often tweak things like font settings to a degree that cannot be recreated on the web. Is there any way to lock down Photoshop, or perhaps run an equivalent of the Office 2010 "Compatability report" that shows the designer where they have designed something that cannot be rendered on a web page. Something like the old-school "web-safe" colour palette, but for an overall design.

  • How do I randomly generate a top-down 2D level with separate sections and is infinite?

    - by Bagofsheep
    I've read many other questions/answers about random level generation but most of them deal with either randomly/proceduraly generating 2D levels viewed from the side or 3D levels. What I'm trying to achieve is sort of like you were looking straight down on a Minecraft map. There is no height, but the borders of each "biome" or "section" of the map are random and varied. I already have basic code that can generate a perfectly square level with the same tileset (randomly picking segments from the tileset image), but I've encountered a major issue for wanting the level to be infinite: Beyond a certain point, the tiles' positions become negative on one or both of the axis. The code I use to only draw tiles the player can see relies on taking the tiles position and converting it to the index number that represents it in the array. As you well know, arrays cannot have a negative index. Here is some of my code: This generates the square (or rectangle) of tiles: //Scale is in tiles public void Generate(int sX, int sY) { scaleX = sX; scaleY = sY; for (int y = 0; y <= scaleY; y++) { tiles.Add(new List<Tile>()); for (int x = 0; x <= scaleX; x++) { tiles[tiles.Count - 1].Add(tileset.randomTile(x * tileset.TileSize, y * tileset.TileSize)); } } } Before I changed the code after realizing an array index couldn't be negative my for loops looked something like this to center the map around (0, 0): for (int y = -scaleY / 2; y <= scaleY / 2; y++) for (int x = -scaleX / 2; x <= scaleX / 2; x++) Here is the code that draws the tiles: int startX = (int)Math.Floor((player.Position.X - (graphics.Viewport.Width) - tileset.TileSize) / tileset.TileSize); int endX = (int)Math.Ceiling((player.Position.X + (graphics.Viewport.Width) + tileset.TileSize) / tileset.TileSize); int startY = (int)Math.Floor((player.Position.Y - (graphics.Viewport.Height) - tileset.TileSize) / tileset.TileSize); int endY = (int)Math.Ceiling((player.Position.Y + (graphics.Viewport.Height) + tileset.TileSize) / tileset.TileSize); for (int y = startY; y < endY; y++) { for (int x = startX; x < endX; x++) { if (x >= 0 && y >= 0 && x <= scaleX && y <= scaleY) tiles[y][x].Draw(spriteBatch); } } So to summarize what I'm asking: First, how do I randomly generate a top-down 2D map with different sections (not chunks per se, but areas with different tile sets) and second, how do I get past this negative array index issue?

  • How to configure an Ubuntu 12.04 virtual server and VMWare ESXi5 the way VMWare would be able to shut it down properly?

    - by Ivan
    I run an Ubuntu 12.04 server as a virtual machine on a VMWare ESXi 5 server. I've configured VMWare to shut the quest machines down the sane way (with an ACPI (if I understand it righ) shutdown signal so that guest OSes would do it). And this works with other VMs (running Windows 7 Professional and openSuSE) but doesn't work with the Ubuntu server - VMWare still offers just to power them off when I ask it to stop the guest. Any ideas how to fix this?

  • python extract from switch output

    - by household2
    I have some info back from a LAN switch as below Vlan 1 is administratively down, line protocol is down Vlan 2 is up, line protocol is up Helper address is 192.168.0.2 Vlan 3 is up, line protocol is up Helper address is not set Vlan 4 is up, line protocol is up Helper address is 192.168.0.2 Vlan 5 is down, line protocol is down Helper address is 192.168.0.2 Vlan 6 is down, line protocol is down Helper address is not set Helper address is not set And the output I'm trying for is Vlan 1,admin down,n/a Vlan 2,up/up, 192.168.0.2 Vlan 3, up/up, not set Vlan 4, up/up, 192.168.0.2 Vlan 5, down/down, 192.168.0.2 Vlan 6, down/down, not set So the helper isn't always there (line 1) sometimes it's set sometimes it isn't, sometimes there are two lines (last Vlan - I only need 1) and the Vlan can have states of admin down, up/up, up/down (not here) and down down. So using Python and pexpect I can get the above output, but I'm having difficulty parsing out the consecutive lines. I've tried enumerate and then use key+1 for the next line, but the fact that there can be 0,1 or 2 lines following the Vlan screws me. Any ideas please?

  • How should I configure my Active Directory servers so that if one goes down, users are not kicked off SQL?

    - by Matty Brown
    Today, we shut down one of our Active Directory servers during office hours to check the loading on a UPS. Since all the server did was provide Active Directory in a separate building incase the main building caught fire, or whatever, we didn't think it would have any effect on our users. Seconds after the server was shut down, we had a dozen phone calls from users experiencing this issue:- [Microsoft SQL Server Login] SQLState: '28000' [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with authentication. Once we realized what had happened, we quickly rebooted the down Active Directory server. Problem solved. But why did this happen. And what if one day a server has a breakdown and is offline for hours, or days? Shouldn't the other Active Directory servers in the domain service authentication requests without disruption to users? We have 3 Windows Server 2003 Standard servers running Active Directory as Domain Controllers with Global Catalogs, all physically located on the same network at Gigabit speeds. I believe the domain was originally Windows Server 2000, or maybe even NT 4.0. Could the issue be to down to old Group Policies inherited from these old server OS's, or some default setting in Active Directory that needs changing?

  • Why is my HP TouchSmart tx2 1025dx shutting down?

    - by Kristy
    I'm having an issue with my HP tx2 1025dx laptop. Sometimes it will spontaneously shut itself off. First, the screen will go out. Next, the computer itself will shut down. This usually occurs when I am doing something that requires a lot of resources, but lately can happen when I am doing something as simple as using an Office app. I think it may be heat related, if I try to boot the laptop after it shuts itself down, it will shut itself down again before startup is complete. If I let it cool down for a while and then come back to it, the computer will boot properly. These shutdowns are always accompanied by high temperatures on the bottom right side, as well as the right side of the keyboard. I am using a laptop cooler with two fans, and it is not making a bit of difference. This is the second TouchSmart we have owned, the first one had the same issues, we sent it in to HP after it finally refused to reboot. They “fixed” it, and it worked fine for about a month before doing the exact same thing. Unfortunately we had bought the second one before the issues began with the original, if I had known this would be a problem, I would not have purchased another TouchSmart. This particular laptop we have had for more than a year and it didn’t start these issues until a couple of months ago. Any suggestions as to how to fix this problem?

  • Graphics Driver problem, ATI Radeon HD 3200, small screen size and slows everything down.

    - by Arvind Jangid
    Regards. I am using a: 2009 Compaq Presario CQ40-415AU Notebook AMD Athlon X2 Dual core Processor 2.1 GHz 1024 MB L2 cache 3GB DDR2 RAM ATI Radeon + HD 3200 Graphics 256 MB, screen is 14 inch widescreen with resolution of 1280*800. I installed Ubuntu 12.04 LTS 32bit on my laptop. It works brilliantly until I installed graphics driver. When I installed the driver, the graphics became slow. Everything slowed down. Even the splash screen resolution changed to something like 640*480. I have liked Ubuntu since 9.10 and for the freedom it provides and its versatility, but graphics problem remains the same. I even installed Ubuntu on a 50 GB partition with 6 GB swap partition. My HDD is 320 GB. Please tell me what is wrong.

  • What collision detection approach for top down car game?

    - by nathan
    I have a quite advanced top down car game and i use masks to detect collisions. I have the actual designed track (what the player see) with fancy graphics etc. and two other pictures i use as mask for my detection collisions. Each mask has only two colors, white and black and i check each frame if a pixel of the car collide with a black pixel of the masks. This approach works of course but it's not really flexible. Whenever i want to change the look of a track, i have to redraw the mask and it's a real pain. What is the general approach for this kind of game? How can i improve the flexibility of such a mask based approach?

  • After how much line of code a function should be break down?

    - by Sumeet
    While working on existing code base, I usually come across procedures that contain Abusive use of IF and Switch statements. The procedures consist of overwhelming code, which I think require re-factoring badly. The situation gets worse when I identify that some of these are recursive as well. But this is always a matter of debate as the code is working fine and no one wants to wake up the dragon. But, everyone accepts it is very expensive code to manage. I am wondering if are any recommendations to determine if a particular Method is a culprit and needs a revisit/rewrite , so that it can broken down or polymophized in an effective manner. Are there any Metrics (like no. of lines in procedure) that can be used to identify such segment of code. The checklist or advice to convince everyone, will be great!

  • Why the amount of 'indexed' images can go down?

    - by Roman Matveev
    I have a site with several thousand of images. All those images included into the sitemap submitted to Google Webmaster Tools. The amount of 'submitted' images is OK, but the amount of 'indexed' is significantly lower than the amount of 'submitted' and it is going DOWN! I'd understand if not all of my images got indexed (however it is also not clear and very frustrating for me) but I can not understand how the indexing can go in the negative direction?! All the images stays on their places. And pages containing them stays unchanged. At least they intended to be. Any thoughts?

  • Unity3D problem. Bullets fall down instead of flying like they should

  • Hide GRUB2 menu UNLESS you hold down Shift key: how to make this happen?

    - by Shasteriskt
    I have a Ubuntu - Windows 7 dual-boot set-up, and I would like to have it that my laptop would boot up Windows 7 unless I press down the Shift key right after boot and bring up the Grub2 menu from which I can choose Ubuntu. I researched on Grub2 and options for etc/default/grub and I have tried playing around with combinations with the GRUB_TIMEOUT and GRUB_HIDDEN_TIMEOUT values, but to no avail. I tried setting the GRUB_HIDDEN_TIMEOUT higher than the GRUB_TIMEOUT thinking that both countdown start simultaneously, but no - GRUB_TIMEOUT only starts after the other is done. Is this behavior achievable? If so, how?

  • Managed servers getting down regularly by Node Manager. WAD?

    - by csoto
    Recently I have been working on a service request where several instances were running, and several technologies were being used, including SOA, BAM, BPEL and others. At a first glance, this may seem to be a Node Manager problem. But on this situation, the problem was at JMS - Persistent Store level. Node Manager can automatically restart Managed Servers that have the "failed" health state, or have shut down unexpectedly due to a system crash or reboot. As a matter of fact, from the provided log files it was clear that the instance was becoming unhealthy because of a persist6ent Store problem. So finally, the problem here was not with Node Manager as it was working as designed, and the restart was being caused by the Persistent Store. After this Persistent Store problem was fixed, everuthing went fine. This particular issue that I worked was on an Exalogic machine, but note that this may happen on any hardware running Weblogic.

  • How to recover organic position in Google results after server down?

    - by ElHaix
    I have several sites that were doing quite well in terms of organic SEO rankings. I have the important sites setup in Google's Webmaster tools. Long story short, the system was down for about two weeks. Now in AdSense and Analytics, I am seeing that the page views are SLOWLY increasing. and I would like to know if there is anything I can do now to try to expedite the process of regaining those positions. Since there were several errors from that server, is it possible that Google will now rank any site from that IP address lower due to those two weeks of errors? Is this something that I just have to let ride out? Thanks.

  • Can emsripten compile down to Canvas-based Js instead of WebGL?

    - by Sebastian Scholle
    I understand that emscripten compiles down LLVM to JS and it converts OpenGL Calls to WebGL. Thats a fairly simple translation. Is there a way to tell emscripten to use some other graphics Library ( for example Pixi JS ) for its rendering code translations? Is the compiled JS code easy to update or would it be better to merge in your own Graphics API that handles WebGL/Canvas calls. IE: can we use a C++ Graphics Wrapper Library that when compiles to JS, will simply plug into our own JS Graphics Wrapper Library? Im assuming YES, but has anyone tried this? And if So, what would be your technique, as my C++ skills are basic.

  • In terms of SEO, is it better to have a URL broken down by folder, or with dashed names?

    - by VictorKilo
    I am creating a friendly url interpreter for my website. I have read dozens of similar topics on this site, but none that seem to address my particular situation. What I want to know is if it's better to have: A well broken down URL where each category is represented by a folder domain.com/1036/OR/Lane/Lowell/Wetleau-Subdivision -OR- A URL which groups all of the categories and terms together domain.com/1036/Wetleau-Subdivision-Lowell-OR-Lane I am asking only in terms of what is best for SEO, not necessarily human readability. My thinking is that it may be better to group them all together like they are in the second example. My reasoning being that all of those terms represent the page and are more likely to draw a result. I am a complete SEO nub though, and I crave some expert guidance. Thank you in advance for any help given.

  • What's the best way to know if your web server goes down?

    - by Mike Christensen
    I noticed my website only got 8 visitors today, which means it probably went down very early this morning and I never noticed. Why it went down is another story. Ideally, I'd like to be emailed if my web server becomes unresponsive or does not return an HTTP 200. Is there either a cloud-based service (either free or pretty cheap) that can monitor your website? If not, is there a good free/open source program I can run on either a Linux or Windows machine that will monitor a website and email me if it goes down? Thanks!

    I hope someone can help me out with this; I use a laptop and I like to play games a lot that are arrow key dependent. So after a while of using my laptop, I accidentally broke the Down Arrow key. So I decided to try and find out how to make the Numpad5 button work as the Numpad Down button while Numlock is on. I was trying to use AutoHotkey, but so far I've had no luck. Can anyone help me out with this? So far the scripts I used that didn't work were Numpad5::NumpadDown or Numpad5::Down. Am I doing something wrong here?
