• Debian 5 server is randomly shutting down.

  - by revofreak

  My debian 5 vps is suffering from random shutdowns.

• can't install sun jdk on ubuntu karmic 9.10

  - by pstanton

  i've just started using a new ec2 install of ubuntu karmic 9.10 and my first task was to install the jdk. when running apt-get install sun-java6-jdk i get the following: Reading package lists... Done Building dependency tree Reading state information... Done Package sun-java6-jdk is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package sun-java6-jdk has no installation candidate i've tried apt-get update as well as adding deb http://us.archive.ubuntu.com/ubuntu/ karmic universe to /etc/apt/sources.list any ideas fellas?

• Spiceworks versus Request Tracker?

  - by dmackey

  We currently utilize Request Tracker for help desk ticketing, we utilize Spiceworks for asset inventorying. I am pondering whether it might be worthwhile to move from RT to Spiceworks for help desk as well. Has anyone used both systems and can provide some insight into any benefits/problems with either system? Or has general philosophical reasons why one should use one solution over the other? Of course, RT is open source and Spiceworks is not - and usually this would be a major item for me - but since Spiceworks is free and takes community involvement fairly actively its not as major of a concern for me (personally).

• iptables -L lags on non localhost or anywhere address

  - by DazSlayer

  I am trying to configure iptables for ubuntu 10.04 and I have a problem with iptables -L lagging on rows where the destination or source address is not localhost or anywhere. The following entries will cause lag on their row: iptables -A INPUT -p tcp --dport 111 -s 192.168.1.14 -j ACCEPT iptables -A INPUT -p tcp --dport 90 -d 192.168.1.14 -j ACCEPT while this does not: iptables -A INPUT -p tcp --dport localhost -s 192.168.1.14 -j ACCEPT iptables -A INPUT -p tcp --dport localhost -d 192.168.1.14 -j ACCEPT I feel like this might be due to iptables checking to see if the ip is reachable. If not, what is the cause, if it is how can I disable it?

• Xubuntu 14.04 with Compton, strange screen tearing, only when playing videos though (advice needed)

  - by LinuxDudester

  Hello beloved community, Yet again I am in need of your great expertise. I ran into a very strange issue and just can't wrap my mind around it. I'm running Xubuntu 14.04 exclusively, with Compton installed. The OS runs great and I have absolutely no screen tearing when I move my windows around, scroll in my web browser, work in Gimp or Photoshop (wine) or even when I play very graphic demanding games, like Metro Last Light, Euro Truck Driver 2 and so on. There's not a tiny bit of tearing to see, but as soon as I play videos, in xbmc, vlc or parole media player the tearing begins (strangely enough this does not apply to youtube videos). I followed all available workarounds on askubuntu and the ubuntu forum,like the 50-xserver-command.conf, startx /etc/X11/Xsession /usr/bin/xbmc-standalone -- -bs or libsdl1.2debian fix and many more, but to no avail. I also tried the Open Source Nouveau display drivers as well, but for some odd reason they don't work so great on my system or at least with my graphics card. Even with Compton installed and configured, I have an extreme amount of screen tearing, as soon as I switch to the proprietary Nvidia drives the screen tearing is gone completely, except for the video playback with xbmc, vlc or parole media player. System info for your reference: OS: Xubuntu 14.04 Linux-x86_64 - Processor: Intel Core i7-4770S CPU @ 3.10GHz - Ram: 16 GB - GeForce GT 750M 1024 MB - Nvidia Driver: 331.38 Has anyone experienced such an odd issue or do you have any advice on how I could fix this? I would appreciate any help! Have a nice day!

• What is the proper way to maintain the angle of a gun mounted on a car?

  - by Blair

  So I am making a simple game. I want to put a gun on top of a car. I want to be able to control the angle of the gun. Basically it can go forward all the way so that it is parallel to the ground facing the direction the car is moving or it can point behind the car and any of the angles in between these positions. I have something like the following right now but its not really working. Is there an better way to do this that I am not seeing? #This will place the car glPushMatrix() glTranslatef(self.position.x,1.5,self.position.z) glRotated(self.rotation, 0.0, 1.0, 0.0) glScaled(0.5, 0.5, 0.5) glCallList(self.model.gl_list) glPopMatrix() #This will place the gun on top glPushMatrix() glTranslatef(self.position.x,2.5,self.position.z) glRotated(self.tube_angle, self.direction.z, 0.0, self.direction.x) print self.direction.z glRotated(45, self.position.z, 0.0, self.position.x) glScaled(1.0, 0.5, 1.0) glCallList(self.tube.gl_list) glPopMatrix() This almost works. It moves the gun up and down. But when the car moves around, the angle of the gun changes. Not what I want.

• How to decide on a price for the project as a freelancer

  - by Shekhar_Pro

  I have seen similar question on this SE site but none comes close to a sure shot answer and many are rather subjective. So i am taking a website as an example to be more objective for you to decide its development price i should quote for the complete work.I would like to have specific figures. In past I have developed many projects for my classmates (Computer science and few .net) when i was in college and there i just arbitrarily quoted the price i will take depending on my mood and customer's ability to pay.. usually ranging from Rs.500 (about $10 USD) to Rs. 1500 (about $30 USD). I have also developed few websites but that was open-source and free. But this time impressed by my work i have got a client that wants to get a website developed similar to this: [ http://www.jeetle.in/ ]. So taking this website as an example tell me how much should i charge for complete work from designing to payment gateway implementation (Excluding the charge the payment gateway provider will take). Few information you might like to consider. I am the only developer on this project if that makes any difference. And i would be using ASP.Net and MSSQL Express for server side processing and jQuery on client. Time period for development offered is about 4 to 6 Weeks. Its like i know my work but not how much I'm worth

• Get to Know a Candidate (6 of 25): Jill Stein&ndash;Green Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Stein is a physician with degrees from Harvard College and Harvard Medical School.  She serves on the boards of Greater Boston Physicians for Social Responsibility and MassVoters for Fair Elections, and has been active with the Massachusetts Coalition for Healthy Communities Jill Stein advocates a "Green New Deal" in which renewable energy jobs would be created to address climate change and environmental issues with the objective of employing "every American willing and able to work". Citing the research of Dr. Phillip Harvey, Professor of Law & Economics at Rutgers University, as evidence of the successful economic effects of the 1930s' New Deal projects, Stein would fund the plan with a 30% reduction in the U.S. military budget, returning US troops home, and increasing taxes on areas such as capital gains, offshore tax havens and multimillion dollar real estate. Stein plans on impacting what she sees as a growing convergence of environmental crises in water, soil, fisheries and forests, through the creation of sustainable infrastructure based in clean renewable energy generation and sustainable communities principles such as increasing intra-city mass transit and inter-city railroads, creating 'complete streets' that safely encourage bike and pedestrian traffic and regional food systems based on sustainable organic agriculture The Green Party of the United States was founded in 1991 as a voluntary association of state green parties. With its founding, the Green Party of the United States became the primary national Green organization in the United States, eclipsing the Greens/Green Party USA, which emphasized non-electoral movement building. The Green Party of the United States of America emphasizes environmentalism, non-hierarchical participatory democracy, social justice, respect for diversity, peace and nonviolence. Their "Ten Key Values," which are described as non-authoritative guiding principles, are as follows: Grassroots democracy Social justice and equal opportunity Ecological wisdom Nonviolence Decentralization Community-based economics Feminism and gender equality Respect for diversity Personal and global responsibility Future focus and sustainability The Green Party does not accept donations from corporations. Thus, the party's platforms and rhetoric critique any corporate influence and control over government, media, and American society at large. Stein has access to 403 electoral votes and is a write-in candidate in GA, IN, and MS Learn more about Jill Stein and Green Party on Wikipedia.

• Collaborative data modelling software?

  - by at01

  I'm trying to find a tool where a lot of people can work on a data model collaboratively. Embarcadero has a an ER application called ER/studio which apparently comes with a repository system that acts like typical version control software. That sounds great except ER/studio is expensive and this is a non-profit and open source organization where we encourage members to even contribute small changes. What's the best solution? Either downloadable software or a web service would work. We don't mind paying, but the cost can't go up with the number of participants...

• What relationship do software Scrum or Lean have to industrial engineering concepts like theory of constraints?

  - by DeveloperDon

  In Scrum, work is delivered to customers through a series of sprints in which project work is time boxed to a fixed number of days or weeks, usually 30 days. In lean software development, the goal is to deliver as soon as possible, permitting early feedback for the next iteration. Both techniques stress the importance of workflow in which software work product does not accumulate in development awaiting release at some future date. Both permit new or refined requirements and feedback from QA and customers to be acted on with as little delay as possible based on priority. A few years ago I heard a lecture where the speaker talked briefly about a family of concepts from industrial engineering called theory of constraints. In the factory, they use an operations model based on three components: drum, buffer, and rope. The drum synchronizes work product as it flows through the system. Buffers that protect the system by holding output from one stage as it waits to be consumed by the next. The rope pulls product from one work station to the next. Historically, are these ideas part of the heritage of Scrum and Lean, or are they on a separate track? It we wanted to think about Scrum and Lean in terms of drum-buffer-rope, what are the parts? Drum = {daily scrum meeting, monthly release)? Buffer = {burn down list, source control system)? Rope = { daily meeting, constant integration server, monthly releases}? Industrial engineers define work flow in terms of different kinds of factories. I-Factories: straight pipeline. One input, one output. A-Factories: many inputs and one output. V-Factories: one input, many output products. T-Plants: many inputs, many outputs. If it applies, what kind of factory is most like Scrum or Lean and why?

• Gmail firing background tasks in Chrome and Firefox

  - by Keith Bloom

  I am experiencing a strange problem with Gmail running on Vista and it started when WindowsUpdate last patched my computer. Since then when Gmail is open in either Chrome or Safari the pointer changes to the Working in Background state every couple of seconds. You can imagine how distracting this is. I have never used Gmail in IE before so I loaded it up, Gmail wanted to load the GoogleTalk ActiveX control which I declined. Now Gmail in IE, I'm using version 8, didn't fire these background processes so I'm thinking it has something to do with GoogleTalk. Has anyone experienced this problem? Also does anyone know how to disable GoogleTalk in FireFox of Chrome.

• Are copyright notices really required?

  - by Alasdair

  Ever since I made my first web page 13 years ago I have followed the pattern of showing a copyright notice in the footer of each page. Over the years the format of this notice has changed in the following way; Copyright © <NAME> yyyy. All rights are reserved. Copyright © <NAME> yyyy © yyyy <NAME> © <NAME> This has generally mirrored the format used by Google. However, I recently noticed that they no longer display a copyright notice on their home page nor have one in their source code/meta tags. I see they still display it on most (if not all) other pages. I understand that Google are very keen to keep the word count down on their homepage, which could be the reason for this sacrafice, but my question is more general and relates to all websites. Since I've always just done it out of habit, I'm hoping someone can explain if/when I a copyright notice is actually required to protect your content and rights. Also, when it is required, is there a format in which the notice must adhere to in order to be valid?

• Do you know the minimum builds to create on any branch?

  - by Martin Hinshelwood

  You should always have three builds on your team project. These should be setup and tested using an empty solution before you write any code at all. Figure: Three builds named in the format [TeamProject].[AreaPath]_[Branch].[Gate|CI|Nightly] for every branch.   These builds should use the same XAML build workflow; however you may set them up to run a different set of tests depending on the time it takes to run a full build. Gate – Only needs to run the smallest set of tests, but should run most if not all of the Unit Test. This is run before developers are allowed to check-in CI – This should run all Unit Tests and all of the automated UI tests. It is run after a developer check-in. Nightly – The Nightly build should run all of the Unit Tests, all of the Automated UI tests and all of the Load and Performance tests. The nightly build is time consuming and will run but once a night. Packaging of your Product for testing the next day may be done at this stage as well. Figure: You can control what tests are run and what data is collected while they are running. Note: We do not run all the tests every time because of the time consuming nature of running some tests, but ALL tests should be run overnight. Note: If you had a really large project with thousands of tests including long running Load tests you may need to add a Weekly build to the mix.     Figure: Bad example, you can’t tell what these builds do if they are in a larger list   Figure: Good example, you know exactly what project, branch and type of build these are for.   Technorati Tags: SSW,SSW Rules,VS2010,VS ALM,Team Build 2010,Team Build

• Adding sub-entities to existing entities. Should it be done in the Entity and Component classes?

  - by Coyote

  I'm in a situation where a player can be given the control of small parts of an entity (i.e. Left missile battery). Therefore I started implementing sub entities as follow. Entities are Objects with 3 arrays: pointers to components pointers to sub entities communication subscribers (temporary implementation) Now when an entity is built it has a few components as you might expect and also I can attach sub entities which are handled with some dedicated code in the Entity and Component classes. I noticed sub entities are sharing data in 3 parts: position: the sub entities are using the parent's position and their own as an offset. scrips: sub entities are draining ammo and energy from the parent. physics: sub entities add weight to the parent I made this to quickly go forward, but as I'm slowly fixing current implementations I wonder if this wasn't a mistake. Is my current implementation something commonly done? Will this implementation put me in a corner? I thought it might be a better thing to create some sort of SubEntityComponent where sub entities are attached and handled. But before changing anything I wanted to seek the community's wisdom.

• Installing maven on Ubuntu by manual download

  - by WebDevHobo

  To install Maven, I downloaded the latest version from the website and then followed these steps: http://maven.apache.org/download.html#Installation The last step, the version control, does not work. It says that 'mvn' is currently not installed and that I should type sudo apt-get install maven2 If I go directly to the mvn file itself, it does work: root@ubuntu:~# /usr/local/apache-maven/apache-maven-2.2.1/bin/mvn --version Apache Maven 2.2.1 (r801777; 2009-08-06 12:16:01-0700) Java version: 1.6.0_21 Java home: /usr/java/jdk1.6.0_21/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux" version: "2.6.32-25-generic" arch: "i386" Family: "unix" So, what am I doing wrong here?

  I have this simple compute shader that basically just takes the input from one image and writes it to another. Both images are 128/128/128 in size and glDispatchCompute is called with (128/8,128/8,128/8). The source images are cleared to 0 before this compute shader is executed, so no undefined values should be floating around in there. (I have the appropriate memory barrier on the C++ side set before the 3D texture is accessed). This version works fine: #version 430 layout (location = 0, rgba16f) uniform image3D ping; layout (location = 1, rgba16f) uniform image3D pong; layout (local_size_x = 8, local_size_y = 8, local_size_z = 8) in; void main() { ivec3 sampleCoord = gl_GlobalInvocationID.xyz; imageStore(pong, imageLoad(ping,sampleCoord)); } Reading values from pong shows that it's just a copy, as intended. However, when I load data from ping with an offset: #version 430 layout (location = 0, rgba16f) uniform image3D ping; layout (location = 1, rgba16f) uniform image3D pong; layout (local_size_x = 8, local_size_y = 8, local_size_z = 8) in; void main() { ivec3 sampleCoord = gl_GlobalInvocationID.xyz; imageStore(pong, imageLoad(ping,sampleCoord+ivec3(1,0,0))); } The data that is written to pong seems to depend on the order of execution of the threads within the work groups, which makes no sense to me. When reading from the pong texture, visible flickering occurs in some spots on the texture. What am I doing wrong here?

• Usage of repository between EF model and code consumer

  - by jim

  I have binary data in my database that I'll have to convert to bitmap at some point. I was thinking whether or not it's appropriate to use a repository and do it there. My consumer, which is a presentation layer, will use this repository. For example: // This is a class I created for modeling the item as is. public class RealItem { public string Name { get; set; } public Bitmap Image { get; set; } } public abstract class BaseRepository { //using Unity (http://unity.codeplex.com) to inject the dependancy of entity context. [Dependency] public Context { get; set; } } public calss ItemRepository : BaseRepository { public List<Items> Select() { IEnumerable<Items> items = from item in Context.Items select item; List<RealItem> lst = new List<RealItem>(); foreach(itm in items) { MemoryStream stream = new MemoryStream(itm.Image); Bitmap image = (Bitmap)Image.FromStream(stream); RealItem ritem = new RealItem{ Name=item.Name, Image=image }; lst.Add(ritem); } return lst; } } Is this a correct way to use the repository pattern? I'm learning this pattern and I've seen a lot of examples online that are using a repository but when I looked at their source code... for example: public IQueryable<object> Select { return from q in base.Context select q; } as you can see no behavior is added to the system by their approach, so I was confused that maybe repository is something else and I got it all wrong. At the end there should be extra benifits of using them right?

• How to make a btrfs snapshot?

  - by MountainX

  My /home partition consists of an entire physical disk. It is formatted as btrfs. I want to snapshot it. I'm confused regarding subvolume naming, in particular. I am aware that there are similar questions, but each similar question seems to be asking something different from what I'm asking (and they are older, which means probably outdated, given the rapid development of btrfs). For example, the answer to this question is apparently not the answer to my question because my /home partition is a separate volume and the man page for btrfs shows a different command for creating snapshots now. another similar problem, no solid solution. someone else as confused as me on the naming issues My question: Starting simple: is this the correct command to take a simple snapshot of my home partition? btrfs subvolume snapshot /home/@home /home/@home_snapshot_20120421 I got really brave and tested it and it does not work. The error is error accessing /home/@home. As shown below, @home is listed. I'm obviously confused on subvolume names. Do I need to use them in creating snapshots? Some examples show taking snapshots of home using /home as the source parameter, but based on examples of root volumes, it seems to me that I need to use /home/@home. Would this command work? And if not, why? btrfs subvolume snapshot /home /home/@home_snapshot_20120421 Is the @ just a naming convention? Is it meaningful at all? Here's some output that may be relevant: btrfs subvolume list /home ID 256 top level 5 path @home I'm not sure what that means, exactly. When I try btrfs device scan it gives an error (e.g. unable to scan the device /dev/sda1). My file system doesn't have any errors. Everything is fine.

• Deleting large no of files on linux eats up CPU

  - by Sanjay

  I generate more than 50GB of cache files on my RHEL server (and typical file size is 200kb so no of files is huge). When I try to delete these files it takes 8-10 hours. However, the bigger issue is that the system load goes to critical for these 8-10 hours. Is there anyway where I can keep the system load under control during the deletion. I tried using nice -n19 rm -rf * but that doesn't help in system load. P.S. I asked the same question on superuser.com but didn't get a good enough answer so trying here.

• Commercial product using a GPL OS

  - by pfried

  we are planning to create a commercial product. The product consists of come MCUs and a small computer (we are developping on a raspberry pi at the moment). The computer needs an operating system as we would like keep things like WLAN and booting as simple as possible. We create some software running on this computer (node.js application). The most operating systems like Arch Linux are licenced under the GPL. The product we would sell contains the computer with preinstalled OS and software. This system operates as a central access point to MCU devices and is able to control them. We use other's software in our product. We do not modify their source code. The product (the computer part) consists of a computer, an OS and software we create. How does the use of an OS affect our own code (licence)? Is there a possibility of avoiding GPL for our own code? eg. shipping the software seperated? Are there any effects to other components of our product, eg. the MCU part? The node.js application delivers a WebApp to the client where it is executed. Are there any effects (As we would like to sell parts of the code as an additional App on the App Stores)? I know we make use of the work of the community and i respect this. The problem is: The software alone is kind of useless without the MCU devices. I do not expect a legal advice.

• Help: Best way to do a TV-out in 7300GT Nvidia video card?

  - by Martin Ongtangco

  I'm planning to recycle my old PC and build a Media Center using an open-source (C#) software called MediaPortal. My old PC has a GeForce 7300GT with a TV-out plug built-in. When I tested it last night, it wouldn't detect my JVC tv (CRT) using the current drivers. I even purchased a new copper-based TV-Out to RCA cable. I searched all 3 AV channels. The video card has 3 output ports: 2 DVI & 1 s-video. I used the s-video with a S-Video to RCA out cable. I swapped between PAL & NTSC So what I did was I downloaded the first version of an Nvidia driver for 7 series cards, but still even with the old console, it couldn't detect the TV. I'm running out of viable ideas. Anyone here had the same problem and fixed it? Any suggestion is appreciated. Thank you!
