• Installation taking a very long time

  - by user290522

  I am installing Ubuntu 14.04(32-bit) on my laptop (Compaq Presario V2000), and after about 7 hours, it is still in Congiguring bcmwl-kernel-source (i386) mode. The messages I read are as follows: ubuntu kernel: [22814.858163] ACPI: \_SB_.PCI0.LPC0.LPC0.ACAD: ACPI_NOTIFY_BUS_CHECK event: unsupported with the numbers in the square brackets increasing. I have had Windows XP professional on this laptop, and I am erasing it. I am not sure if I should turn off the laptop, and start all over again. About 4 years ago I installed Ubuntu on this laptop, and that was very fast. The only problem I encountered was my wireless, and could not make it to work, and switched back to Windows. I appreciate any comments regarding this installation taking such a long time.

• How to get multiple open-source projects to use a standard way of doing something.

  - by Marco

  Problem In the last couple weeks, I've used 3 different "repository" tools (listed in alphabetical order): gradle ivy maven I'm calling them "repository" tools because I've also used sbt -- which fortunately uses ivy to manage it's cache or local repository. Each of these tools will create it's own repository. The defaults are: ~/.m2/repository for maven ~/.gradle/cache ~/.ivy2/cache Why can't they all use the same cache? Goal I'd like to change the world so that all three build tools could use the same cache. I'm looking for advice about issues I'm likely to run into and smart ways to get around them. By "use the same cache", I do not mean "retrieve from another build tool's cache". I mean "retrieve from and store in another build tool's cache". While I could go ahead and submit issues to the three projects, I know from experience (as a developer on an open source project), that if you want something done, you're best off getting it done yourself. Also, it seems like I need to get all 3 communities on board to some degree. What is the recommended approach for getting this kind of thing done? How do I approach the different communities? Do I work on patches for the 3 different projects, or would it be better off to create my own "interface" project that deals with these issues and have the 3 tools interface with that? Is this a standards question that I need to address on that front? Lastly, if I'm missing something and this is possible (in an globally configurable fashion), then please let me know.

• insert system disk error after switchting SATA cables

  - by Matthias

  I have 5 hard disks built in my computer, two connected by IDE cables, three by SATA. Today I had to return two of the SATA cables to my room mate. So I grabbed another one I had floating around and connected the remaining disk by unplugging my DVD R/W. Now I receive the 'insert system disk and press enter' error after booting. Disks and cables seem to be fine, since all the disks are recognized in the BIOS. Also, I can mount the disks using a live CD w/o problems. I also tried different orderings of the cables (i.e. plugging the disks in different plugs on the mainboard), I'm not sure if that even matters using SATA. Any Ideas what might be the problem here? The OS installed are Windows 7 and Ubuntu 10, the bootloader installed is GRUB. PS: No RAID involved, JBOD.

• Any good C++ Component/Entity frameworks?

  - by Pat

  (Skip to the bold if you want to get straight to my question :) ) I've been dabbling in the different technologies available out there to use. I tried Unity and component based design, managing to get a little guy up and running around a map with basic pathfinding. I really loved how easy it was to program using components, but I wanted a bit more control and something more 2D friendly, so I went with LibGDX. I looked around and found 2 good frameworks for Java, which are Artemis and Apollo. I didn't like Artemis much, so I went with Apollo, which I loved. I managed to integrate it with Box2D and get a little guy running around bouncing balls. Great! But since I want to try out most of the options, there is still C++/SFML that I haven't tried yet. Coming from a Java/C# background, I've always wanted to get my hands dirty with C++. But then, after some looking around, I noticed there aren't any Component-Based frameworks for me to use. There's a somewhat done porting of Artemis, but, aside from not being completely finished, I didn't quite like Artemis even in Java. I found Apollo's approach much more.. logical. So, my question is, are there any good Component/Entity frameworks for C++ that I can use that are similar to Artemis, or preferably, Apollo?

• Setup staging with multiple SVN

  - by Kapil Sharma

  We are a startup, setting new environments for product to be released soon. Planned server structure with planned release flow is as shown in below image It ideally have a local server (or Staging server, shown in green) in local office, without public IP address and Production Server (Red) at Amazon EC2. Both local and production server have there own SVN copy. Management here want to update production server with production SVN and without providing its access to developers (including freelancers/contract employees). So for developers, there is a Local SVN on local server. Another purpose of local SVN to keep a copy of code on local server, which is under our direct control. Although there are some technical concerns like how will code at local server will be updated from local SVN and commit on production SVN but bigger question is, is that structure correct? Major requirement remain don't provide production SVN access to developers. What are other possible options to achieve that? Another minor question, if suitable here, if above structure is correct, is it possible for a SVN checkout to get updated from one SVN (Local SVN) but commit to other (Production SVN)? If yes, How? edit An answer has been accepted but for bounty, I'm still looking for answer Is that structure correct? Its pros/Cons? Technical solution is already provided by accepted answer.

• Using standard e-mail address as user system wide name

  - by PeterMmm

  I'm going to re-build a very old Lotus Notes infrastructure coming from 4.x towards 8.5. I'm trying to setup Domino so that all user names should be of a single string or the internet e-mail address. For example the user "John Smith/ACME" should be in the whole system jsmith or [email protected] . I still get jsmith/ACME all around. Where it is most annoying is in the NAB when creating a new message. Is there a way to get all addresses in uniform standard e-mail adress format at least in mail ? The mixup in the destination like "John Smith/ACME, [email protected]" confused the users.

• Pls help Installation has ruined laptop

  - by user287694

  Hi this was my time using Linux. So I installed Ubuntu from Windows 7 via USB. After booting into Ubuntu I proceeded to do a full install over windows. This seemed to be going fine but at the point where I was to sign up to Ubuntu one it froze. After awhile maybe 30 mins I realised nothing was going to happen, so I restarted. Now after the bios options bit passes all I get is a prompt flashing at the top left of a black screen. I have tried booting up via USB option but nothing happens, I have tried this 6 or 7 times with fresh usb each time and also with lubuntu. I'm not sure if I have correctly made a live usb obviously I believe I have been but being new I can't guarantee this. Can anyone help me get some functional out of my laptop. Thanks Ben

• Refresh banshee album art

  - by kmassada

  I usually just copy ~/.config/banshee-1, and ~/.gconf/apps/banshee-1 when i'm moving from one computer to the other, if I keep the path of the folders. I get to keep my music library intact with the playlists I have. The problem with this method is that, the album arts doesn't carry over nicely. You'd have to play every album to get the album art to appear. Anyone knows a workaround, to maybe force banshee to reload all album art? I saw this, but not quite what my issue is? I tried banshee --fetch-artwork, but didn't work too well kenneth@dv7:~$ banshee --fetch-artwork [Warn 11:23:38.200] DBus support could not be started.

• Toolkit & Habits for Linux Network & System Administration [closed]

  - by slashmais

  I am tasked with the administration of a small office network as well as several workstations running mostly Debian and Ubuntu. There are two servers: one database & print-server, and one backup & file server. Being relatively new to this side of things, knowing enough to help myself to some degree on Linux, I would like to know what software tools and tasks/habits I can use/acquire to learn this field and be effective while doings so. I don't need to know what is the best, just what a newbie sys-admin can use as a starter-pack to learn and use as a base to grow into proper system administration. [edit] What I need is those few basic tools to start with, and the kind of things I need to do regularly, e.g.: which logs to check, when & what to monitor, the kind of 'right' place to start and to which I can ad as I need.

• Run a pool of processes in shell

  - by viraptor

  I'm looking for an easy method to run N selected processes at the same time with one command. It should put all the output on my terminal and shut down all of them when I exit with ctrl+c. Is there any existing app that does this? I'm thinking of some thing like exec_many 10 foo - it should keep 10 foos running and respawn any that dies.

• Hide Outlook envelope in system tray

  - by thorseye

  When I get a new email in Outlook 2003 I get two notifications; one is the envelope in the system tray, and one is the fading noticiation message in the lower right corner. If I click the notification message, the envelope will never disappear, even if all emails are read. If Outlook is restarted the envelope disappears. If I right click the envelope and choose "Hide envelope" I have to go into the settings and set the Show envelope option to true again to see the envelope. I want the envelope, but only when there are any unread emails in my inbox. How do I fix this?

• Physically moving a hard drive from older iMac (c2d) to new iMac (i7) ?

  - by Inshim

  Instead of my usual habit of using superduper to mirror my drive to a new computer, I just physically moved the hard drive from an older iMac to a new one. But... it now doesn't boot, getting stuck at the apple logo screen. Since the hard drive that came with the new iMac works well, and my old drive works well when I return it to the older iMac, I conclude that there is some problem at the system/kernel level due to the different hardware. In the past I did similar things (e.g. starting a C2D machine from a Core Duo in target disk mode), so perhaps the change in architecture to the i5/i7 is too problematic? The main point: do you know of any way to get the system to rebuild for itself the proper versions of the system components when booting? Are there certain directories that I can safely delete to make that happen? Thanks

• Architecture Standards &ndash; BPMN vs. BPEL for Business Process Management

  - by pat.shepherd

  I get asked often which business process standard an organization should use; BPMN or BPEL?  As I explain to folks, they both have strengths.  Here is a great article that helps understand the benefits of both and where to use them.  The good news is that, with Oracle SOA Suite and BPM suite, you have the option and flexibility to use both in the same SCA model and runtime container.  Good stuff. Here is the great article that Mark Nelson wrote: The right tool for the right job BPEL and BPMN are both ‘languages’ or ‘notations’ for describing and executing business processes. Both are open standards. Most business process engines will support one or the other of these languages. Oracle however has chosen to support both and treat them as equals. This means that you have the freedom to choose which language to use on a process by process basis. And you can freely mix and match, even within a single composite. (A composite is the deployment unit in an SCA environment.) So why support both? Well it turns out that BPEL is really well suited to modeling some kinds of processes and BPMN is really well suited to modeling other kinds of processes. Of course there is a pretty significant overlap where either will do a great job What BPM adds to SOA Suite | RedStack

• Install Lubuntu w/o Disc or Flash Drive?

  - by Seib

  My WinXP desktop was recently blasted with a few bits of malware. I removed the malware but the damage is done, and my OS is finally at its end; it's barely chugging along as it is. So, I'm figuring what I'd like to do is replace the OS with Lubuntu, which I know is a lightweight, heavily WinXP-esque distro of Linux. However, every article, every explanation, I've read online has stated I need either a 4+ GiB flash drive or a burnable CD. Well, I have a flash drive, but it's only 1 GiB; and I have a disc burner, but no disc. So, frankly, I doubt I'll be able to do it. But hey, I figured I might as well ask away here on AU; what have I got to lose? So my question is this: would it be possible to replace my WinXP OS w/ Lubuntu without using either a 4+ GiB flash drive or a burnable CD? Thanks very much. I appreciate any help you could give.

• Cheapest Embedded System with Wireless Connectivity?

  - by geeko

  Problem: I'm trying to capture some information coming from keyboard, mouse and barcode reader connected to some PC via PS/2, USB and/or RS-232, before information get to PC and send it over the Internet to some central server. I'm thinking to do so by using some kind of hardware interface (middleware, if you like) between PC and input devices. I thought this interface can be embedded PC, PDA or simply some mobile phone with wireless connectivity. PS/2 and RS-232 could be converted to USB using some USB convector/hub that connects to one of these interface systems. Then some special API programming take place to communicate between PC, input devices and wireless server, in the form of application running on the interface system. What's the cheapest solution that can achieve this? Or possibly any other solution?

• Python: Check existence of shell command before execution

  - by Gabriel L. Oliveira

  Hi all. I'm trying to find a way to check the existence of a shell command before its execution. For example, I'll execute the command ack-grep. So, I'm trying to do: import subprocess from subprocess import PIPE cmd_grep = subprocess.Popen(["ack-grep", "--no-color", "--max-count=1", "--no-group", "def run_main", "../cgedit/"], stdout=PIPE, stderr=PIPE) Than, if I execute cmd_grep.stderr.read() I receive '' like the output. But I don't have the command ack-grep on my path. So, why Popen is not putting the error message on my .stderr variable? Also, is there a easyer way to do what I'm trying to do?

• Why no multiple instances of Firefox on Linux as on Windows?

  - by Jack

  On Windows If I run Firefox as user jack, and then try to start another instance of firefox I will be unable to, as one is already running. If I choose to run firefox as administrator, then I can have two instances of firefox, separate from each other side by side, because they are under different user accounts. This does not seem to be true on Linux. As user jack if I start firefox, like on windows I am unable to start a new instance. If I open a terminal and change to root, set XAUTHORITY to jacks .Xauthority and try to start firefox as root....I get the error that firefox is already running. Why is this? Please don't spare any technical details in your answers....thankyou.

• Screen Lag/Running Slow

  - by Nick M

  I am having trouble with Ubuntu 12.10. Everything is working fine, although there is a slight problem. It seems to lag every once in a while, as in I will move the mouse, then about two seconds later the cursor will actually move on the screen. Is there any way to fix this? This is my first day using Ubuntu and I put it on a computer I built myself. I don't have much experience so a detailed answer would be very much appreciated.

• /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor disappeared on ubuntu 11.10

  - by Bob

  I have an Ubuntu 11.10 server that has been up for 210 days. I have been frequently doing apt-get upgrade every few weeks, and this time I noticed that my server load average just shot up. The last time this happened between upgrades, it was because the cpu scaling governor was set to ondemand. But this time when I tried to list the contents of /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor the file is missing. There isn't even a cpufreq folder anymore! How do I fix this and ensure there is no cpu scaling going on?

• Preparing a new physical system with VMWare

  - by Max

  I need to create a new installation of Windows, but at the same time I need this computer. So I decided to create a new physical disk from within VMWare, install windows/drivers/software and then just replace the HDD in the computer. I've bought a new HDD, split it into two partions and installed Windows 7 using the VMWare's ability to use phusical disks. I can see the windows files and directories that have been created on this partition, but when I'm replacing the HDD in the host machine it cannot boot from it. Why is that? Is it at all possible to create a bootable physical disk with VMWare or I should create a virtual disk and then use some HDD imaging tool to copy the HDD image to a physical disk? Maybe there's a better way of installing a new system and working on the computer at the same time?

• Monitoring System for the cloud?

  - by Maxim Veksler

  I need a monitoring system, much like ganglia / nagios that is build for the cloud. I need it to support : Adding / removing nodes dynamically. (Node shuts down, dose not imply node failure...) Dynamic node based categorization, meaning node can identify them self as being part of group X (ganglia gets this almost right, but lacks the dynamic part...) Does not require multicast support (generally not allowed in cloud based setups) Plugins for recent cool stuff such as Hadoop, Cassandra, Mongo would be cool. More features include: External API, web interface and co. I've looked at Ganglia, munin and they both seem be almost there (but not exactly). I would also go for reasonably priced Software as Service solution. I'm currently doing research, so Suggestions are highly appreciated. Thank you, Maxim

• Appropriate level of granularity for component-based architecture

  - by Jon Purdy

  I'm working on a game with a component-based architecture. An Entity owns a set of Component instances, each of which has a set of Slot instances with which to store, send, and receive values. Factory functions such as Player produce entities with the required components and slot connections. I'm trying to determine the best level of granularity for components. For example, right now Position, Velocity, and Acceleration are all separate components, connected in series. Velocity and Acceleration could easily be rewritten into a uniform Delta component, or Position, Velocity, and Acceleration could be combined alongside such components as Friction and Gravity into a monolithic Physics component. Should a component have the smallest responsibility possible (at the cost of lots of interconnectivity) or should related components be combined into monolithic ones (at the cost of flexibility)? I'm leaning toward the former, but I could use a second opinion.
