• Add xcode-select to PATH vs. Install Xcode Command Line Tools?

  - by MattDiPasquale

  Now with Xcode 4.5, is it OK to just add the following line to my ~/.bash_profile rather than installing the Xcode Command Line Tools? export PATH="$PATH:`xcode-select -print-path`/usr/bin:`xcode-select -print-path`/Toolchains/XcodeDefault.xctoolchain/usr/bin" Note: Xcode says the following about Command Line Tools: Before installing, note that from within Terminal you can use the XCRUN tool to launch compilers and other tools embedded within the Xcode application. Use the XCODE-SELECT tool to define which version of Xcode is active. Type "man xcrun" from within Terminal to find out more.

• How to turn off screen (DPMS) together with locking session in KDE?

  - by gertvdijk

  First of all, I'm aware a similar question for GNOME is asked here: "Switch off laptop backlight when locking screen". Objective I would like to turn off my screen on locking the session for power saving reasons. Actual problem Locking the screen on Kubuntu (KDE) inevitably triggers the screensaver as far as I can see. There's no screensaver option other than 'Blank screen' together with its background colour set to black that comes just close to my goal. It blanks the screen, but doesn't turn off the screen. Screen's backlight will still be on and not saving any power. Current workaround A workaround via a script + shortcut key is possible, however, it's just a workaround since it doesn't trigger on all ways to lock the session. Therefore, I think it should be possible to have it done more elegantly, for example by providing this option in KDE's configuration dialog of the screensaver. The workaround I am now using is the following. A script that locks the screen and turns off the screen: #!/bin/bash qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock xset dpms force standby and let it run with a shortcut key via a custom menu entry. It works. Here's why I consider it to be a workaround rather than a solution. It doesn't work for other ways to trigger the locking of the session. My actual question(s) Do I need to touching/patching KDE's source? If not what are my options? If so, could someone point me to where I can get started? what do you think is the recommended place in the GUI for configuration? I'm using Kubuntu 12.04 and willing to upgrade to KDE 4.9 or waiting for the 12.10 release.

• The battery indicator in Unity panel not showing up

  - by user61415

  I installed Ubuntu 12.04 with Wubi. Well after being completely dazzled with the amount of free content in the Software Centre, I decided to go deeper and start messing with settings. Well after changing the screen brightness the highest level I noticed that there wasn't an indicator for how much battery was left in my laptop. I looked up online on got 2 suggestions on how to fix: Right click on the Unity panel and add an indicator Set it to show in the power settings menu. Well I did both when I right click at the top menu nothing comes up and setting it to show does nothing either. Then I tried installing something in the Software Centre. I got something but when I activated it it said I had 0% power left even though I was charging and at %100 according the Light in the front of my laptop. So now I'm thinking that it doesn't even recognise my computer as a laptop which is weird because in the display settings it says my screen size is set to laptop. How can I install it? I don't know what version it is other then Ubuntu 12.04 and no matter what the icon does not appear with the

• With HTML and CSS, how to have an image that is vertically aligned with a horizontal line?

  - by sungod000

  I'd like the image on the left to be adjacent to the horizontal line on the right (bottoms lining up flush). It should be responsive so that the line can change widths as needed. Right now, the image is sitting on top of the line, not beside it. Here is the HTML <div> <img src="image.png"> <hr> </div> Here is the CSS img { float:left } hr { width:100% } How to make this happen?

• Mac OSX server command equivalent for dhclient?

  - by John Hall

  Is there an MacOS command that makes a dhcp request, and renews the old lease, drops it for a new one, or usefully reports errors or lack of response from a dhcp server? This would both help fix networking on the machine after problems on the network without rebooting and would also be useful to diagnose wider networking problems from a mac. I can not find any command equivalent of dhclient though obviously some component must be serving this purpose. The question is, is that component exposed to a command line interface? I am biased to the command line for these features and may have overlooked settings panels or tools that might solve it using a gui interface. I believe this question is at the heart of this other question: Is there an equivalent command for 'init.d/networking restart' in OS X

• Netinstalling CentOS if the gateway is in a different subnet

  - by James Lawrie

  I have a KVM host (A) running a virtual machine (B). They each have their own external IP address and the networking is setup using bridging between eth0 and br0 on A. B uses eth0, with A being the gateway. The problem is that the two external IP addresses are on different subnets (different /8s in fact) so by default, B claims it cannot reach A (Network Unreachable). I can resolve this by adding a static route on B: echo "any host gateway_ip dev eth0" > /etc/sysconfig/static-routes Modifying /etc/init.d/networking to reload the gateway after applying static routes (I only added the final line before fi): if [ -f /etc/sysconfig/static-routes ]; then grep "^any" /etc/sysconfig/static-routes | while read ignore args ; do /sbin/route add -$args done route add default gw "${GATEWAY}" fi If I then restart networking, it comes online. How can I do this (or work around it some other way) prior to the system being installed, ideally inside an Anaconda kickstart file?

• How to stop switchable graphics from switching to high-power GPU when charging the laptop?

  - by Saifallah

  I've an Acer laptop with Windows 7 64 bit and an ATI Radeon HD 6550M Graphics card. Whenever I connect the power to charge the battery it automatically switches to the high-power GPU (ATI) instead of the low-power (Intel) GPU. There's an option in the bios to stop such thing but it makes the GPU runs always on high-power and I can't switch to the low-power GPU. How can I prevent the switchable graphics from automatically using the high-power GPU when charging?

• How to host a scalable social networking app

  - by christopher-mccann

  I am in the middle of developing a social networking application for a very select user niche which could scale to a few million users. Right now I have always hosted applications on RackSpace Cloud and I have no issues with them at all - always been a really good service and never had any downtime. My question is though does anyone think that cloud computing is not the way to host scalable web apps? Or can anyone with experience of this recommend a better solution. I have always shunned trying to run big servers from my own facilities as I think it seems silly to go to the expense of bringing in big alternative power supplies and all the other necessary precautions when other companies already do this. I looked at managed hosting services but this proved to be a bit too expensive for us at the start and the scalability of it wasnt good enough - it would take a day or two to get a new server provisioned. Therefore I ended up on a cloud platform. If anyone has any recommendations or advice it would be greatly appreciated.

• Box Selection and Multi-Line Editing with VS 2010

  - by ScottGu

  This is the twenty-second in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. I’ve already covered some of the code editor improvements in the VS 2010 release.  In particular, I’ve blogged about the Code Intellisense Improvements, new Code Searching and Navigating Features, HTML, ASP.NET and JavaScript Snippet Support, and improved JavaScript Intellisense.  Today’s blog post covers a small, but nice, editor improvement with VS 2010 – the ability to use “Box Selection” when performing multi-line editing.  This can eliminate keystrokes and enables some slick editing scenarios. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Box Selection Box selection is a feature that has been in Visual Studio for awhile (although not many people knew about it).  It allows you to select a rectangular region of text within the code editor by holding down the Alt key while selecting the text region with the mouse.  With VS 2008 you could then copy or delete the selected text. VS 2010 now enables several more capabilities with box selection including: Text Insertion: Typing with box selection now allows you to insert new text into every selected line Paste/Replace: You can now paste the contents of one box selection into another and have the content flow correctly Zero-Length Boxes: You can now make a vertical selection zero characters wide to create a multi-line insert point for new or copied text These capabilities can be very useful in a variety of scenarios.  Some example scenarios: change access modifiers (private->public), adding comments to multiple lines, setting fields, or grouping multiple statements together. Great 3 Minute Box-Selection Video Demo Brittany Behrens from the Visual Studio Editor Team has an excellent 3 minute video that shows off a few cool VS 2010 multi-line code editing scenarios with box selection:   Watch it to learn a few ways you can use this new box selection capability to optimize your typing in VS 2010 even further: Hope this helps, Scott P.S. You can learn more about the VS Editor by following the Visual Studio Team Blog or by following @VSEditor on Twitter.

• Cropping a line (laser beam) in XNA

  - by electroflame

  I have a laser sprite that I wish to crop. I want to crop it so when it collides with an item, I can calculate the distance between the starting point, and the ending point, and only draw that. This eliminates the "overdraw" of a laser drawing past an item. Essentially, I'm trying to crop a line, but also keep that line "attached" to the nose of my ship. The line should not be drawn past the nose of my ship, that should be the starting point. There is no rotation to worry about. Currently, I thought that doing this through SpriteBatch would be best. This is my current Spritebatch code: spriteBatch.Draw(Laser.sprite, new Rectangle((int)Laser.position.X, (int)Laser.position.Y, Laser.sprite.Width, LaserHeight), new Rectangle(0, 0, (int)(Laser.sprite.Width), LaserHeight), new Color(255, 255, 255, (byte)MathHelper.Clamp(Laser.Alpha, 0, 255)), Laser.rotation, new Vector2(Laser.sprite.Width/2, LaserHeight/2), SpriteEffects.None, 0); But this doesn't quite work. It does only draw part of the sprite, but when LaserHeight is incremented, it lengthens the line in both ways! I believe this is due to some stupid error on my part with the Origin of the draw. Quick recap: I need to have my laser sprite drawn with the bottom of it at the nose of my ship, and then use LaserHeight to crop the image so only part of it is drawn. I have a feeling my explanation is a bit...lacking. So if you require more information, please say so and I will try to provide more information. Thanks in advance!

• Why i disconnect every few seconds? using USB wireless adapter

  - by Rev3rse

  i know it's for ubuntu questions..but mint and ubuntu are very similiar and i had the same problem with linux ubuntu too..so i think this is the right place for my question anyway i don't have experience with drivers and other things,after installing Linux on my machine( i did dist-upgrade btw) everything seem to be great because i didn't have to install any driver, after a while i realized that my connection stop after few minutes(actually it shows that I'm connected but it's not) so i have to reconnect and after few minutes it disconnect again. I'm using Alfa USB wireless adapter AWS036H, and my Linux version is 11 i think the driver i'm using is Realtek i searched in the Internet and i found nothing. these are some outputs of few things

• why is $0 set to -bash?

  - by James Shimer

  First login process name seems to be set to "-bash", but if I subshell then it becomes "bash". for example: root@nowere:~# echo $0 -bash root@nowere:~# bash root@nowere:~# echo $0 bash -bash is causing some scripts to fail, such as . /usr/share/debconf/confmodule exec /usr/share/debconf/frontend -bash Can't exec "-bash": No such file or directory at /usr/share/perl/5.14/IPC/Open3.pm line 186. open2: exec of -bash failed at /usr/share/perl5/Debconf/ConfModule.pm line 59 Anyone know the reason $0 is set to -bash?

• Getting a 'base' Domain from a Domain

  - by Rick Strahl

  Here's a simple one: How do you reliably get the base domain from full domain name or URI? Specifically I've run into this scenario in a few recent applications when creating the Forms Auth Cookie in my ASP.NET applications where I explicitly need to force the domain name to the common base domain. So, www.west-wind.com, store.west-wind.com, west-wind.com, dev.west-wind.com all should return west-wind.com. Here's the code where I need to use this type of logic for issuing an AuthTicket explicitly:private void IssueAuthTicket(UserState userState, bool rememberMe) { FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, userState.UserId, DateTime.Now, DateTime.Now.AddDays(10), rememberMe, userState.ToString()); string ticketString = FormsAuthentication.Encrypt(ticket); HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, ticketString); cookie.HttpOnly = true; if (rememberMe) cookie.Expires = DateTime.Now.AddDays(10); // write out a domain cookie cookie.Domain = Request.Url.GetBaseDomain(); HttpContext.Response.Cookies.Add(cookie); } Now unfortunately there's no Uri.GetBaseDomain() method unfortunately, as I was surprised to find out. So I ended up creating one:public static class NetworkUtils { /// <summary> /// Retrieves a base domain name from a full domain name. /// For example: www.west-wind.com produces west-wind.com /// </summary> /// <param name="domainName">Dns Domain name as a string</param> /// <returns></returns> public static string GetBaseDomain(string domainName) { var tokens = domainName.Split('.'); // only split 3 segments like www.west-wind.com if (tokens == null || tokens.Length != 3) return domainName; var tok = new List<string>(tokens); var remove = tokens.Length - 2; tok.RemoveRange(0, remove); return tok[0] + "." + tok[1]; ; } /// <summary> /// Returns the base domain from a domain name /// Example: http://www.west-wind.com returns west-wind.com /// </summary> /// <param name="uri"></param> /// <returns></returns> public static string GetBaseDomain(this Uri uri) { if (uri.HostNameType == UriHostNameType.Dns) return GetBaseDomain(uri.DnsSafeHost); return uri.Host; } } I've had a need for this so frequently it warranted a couple of helpers. The second Uri helper is an Extension method to the Uri class, which is what's used the in the first code sample. This is the preferred way to call this since the URI class can differentiate between Dns names and IP Addresses. If you use the first string based version there's a little more guessing going on if a URL is an IP Address. There are a couple of small twists in dealing with 'domain names'. When passing a string only there's a possibility to not actually pass domain name, but end up passing an IP address, so the code explicitly checks for three domain segments (can there be more than 3?). IP4 Addresses have 4 and IP6 have none so they'll fall through. Then there are things like localhost or a NetBios machine name which also come back on URL strings, but also shouldn't be handled. Anyway, small thing but maybe somebody else will find this useful.© Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET  Networking   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Frequent Disconnects ubuntu desktop 12.10 x64 intel 82579V e1000e

  - by user112055

  I'm having frequent disconnects with my new install of Ubuntu 12.10. I tried updating the kernel driver to the latest intel release to no avail. My expertise is spent. It happens anywhere between 1 min and 10 min. Any ideas? syslog: Dec 1 13:51:39 andromeda kernel: [ 972.188809] audit_printk_skb: 6 callbacks suppressed Dec 1 13:51:39 andromeda kernel: [ 972.188813] type=1701 audit(1354398699.418:199): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188817] type=1701 audit(1354398699.418:200): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188820] type=1701 audit(1354398699.418:201): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188823] type=1701 audit(1354398699.418:202): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188825] type=1701 audit(1354398699.418:203): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.331419] type=1701 audit(1354398699.558:204): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=2 compat=0 ip=0x7f26777d96b0 code=0x50000 Dec 1 13:53:12 andromeda NetworkManager[1115]: <info> (eth0): carrier now OFF (device state 100, deferring action for 4 seconds) Dec 1 13:53:12 andromeda kernel: [ 1064.894387] e1000e: e1000e: eth0 NIC Link is Down Dec 1 13:53:16 andromeda NetworkManager[1115]: <info> (eth0): device state change: activated -> unavailable (reason 'carrier-changed') [100 20 40] Dec 1 13:53:16 andromeda NetworkManager[1115]: <info> (eth0): deactivating device (reason 'carrier-changed') [40] Dec 1 13:53:16 andromeda NetworkManager[1115]: <info> (eth0): canceled DHCP transaction, DHCP client pid 5946 Dec 1 13:53:16 andromeda avahi-daemon[890]: Withdrawing address record for fe80::ea40:f2ff:fee2:4d86 on eth0.

• Why is my machine unable to mount my SMB drives ("CIFS VFS: Error connecting to socket. Aborting operation", return code -115)?

  - by downbeat

  I have a machine running Precise (12.04 x64), and I cannot mount my SMB drives (I have 3, we'll call them public, private and download). It used to work (a week or two ago) and I didn't touch fstab! The machine hosting the shares is a commercial NAS, and I'm not seeing anything that would indicate it's an issue with the NAS. I have an older machine which I updated to Precise at the same time (both fresh installed, not dist-upgrade), so should have a very similar configuration. It is not having any problems. I am not having problems on windows machines/partitions either, only one of my Precise machines. The two machines are using identical entries in fstab and identical /etc/samba/smb.conf files. I don't think I've ever changed smb.conf (has never mattered before). My fstab entries all basically look like this: //10.1.1.111/public /media/public cifs credentials=/home/downbeat/.credentials,iocharset=utf8,uid=downbeat,gid=downbeat,file_mode=0644,dir_mode=0755 0 0 Here's the dmesg output on boot: [ 51.162198] CIFS VFS: Error connecting to socket. Aborting operation [ 51.162369] CIFS VFS: cifs_mount failed w/return code = -115 [ 51.194106] CIFS VFS: Error connecting to socket. Aborting operation [ 51.194250] CIFS VFS: cifs_mount failed w/return code = -115 [ 51.198120] CIFS VFS: Error connecting to socket. Aborting operation [ 51.198243] CIFS VFS: cifs_mount failed w/return code = -115 There are no other errors I see in the dmesg output. Originally when I ran 'testparm -s', the output contained these lines ERROR: lock directory /var/run/samba does not exist ERROR: pid directory /var/run/samba does not exist Here's the samba related programs I have installed: $ dpkg --list|grep -i samba ii libpam-winbind 2:3.6.3-2ubuntu2.3 Samba nameservice and authentication integration plugins ii libwbclient0 2:3.6.3-2ubuntu2.3 Samba winbind client library ii nautilus-share 0.7.3-1ubuntu2 Nautilus extension to share folder using Samba ii python-smbc 1.0.13-0ubuntu1 Python bindings for Samba clients (libsmbclient) ii samba-common 2:3.6.3-2ubuntu2.3 common files used by both the Samba server and client ii samba-common-bin 2:3.6.3-2ubuntu2.3 common files used by both the Samba server and client ii winbind 2:3.6.3-2ubuntu2.3 Samba nameservice integration server $ dpkg --list|grep -i smb ii dmidecode 2.11-4 SMBIOS/DMI table decoder ii libsmbclient 2:3.6.3-2ubuntu2.3 shared library for communication with SMB/CIFS servers ii python-smbc 1.0.13-0ubuntu1 Python bindings for Samba clients (libsmbclient) ii smbclient 2:3.6.3-2ubuntu2.3 command-line SMB/CIFS clients for Unix ii smbfs 2:5.1-1ubuntu1 Common Internet File System utilities - compatibility package $ dpkg --list|grep -i cifs ii cifs-utils 2:5.1-1ubuntu1 Common Internet File System utilities ii libsmbclient 2:3.6.3-2ubuntu2.3 shared library for communication with SMB/CIFS servers ii smbclient 2:3.6.3-2ubuntu2.3 command-line SMB/CIFS clients for Unix I originally noticed that my other machine had "libpam-winbind" and "nautilus-share" installed and the machine with the issue did not. Installing those two packages solved my errors with 'testparm -s', but did not fix my issue. Finally, I tried to purge and reinstall these packages smbclient smbfs cifs-utils samba-common samba-common-bin Still no luck. Again, it used to work; now it doesn't. Very similarly configured machine works (but some packages are out of date on the working machine). The NAS has only one interface/IP address, nmblookup works to find it's IP from it's hostname (from the machine with the issue) and it responds to a ping. Please any help would be great. I've been searching on AskUbuntu, SuperUser, ubuntuforums and plain old search engines for a week now and it's driving me crazy!

• Realtek RTL8111/8168B wired network doesn't work anymore

  - by Radar4002

  This sounds like it's a common problem upgrading 11.04, but I am having trouble finding a common solution, and one that will work for me. I just applied updates via the update manager and now my wired network connection is down. I know Ubuntu network settings is the issue, because I have a dual-boot with Win 7 and my network/internet is fine on Win 7. I don't know too much about networking, so what can I do to trouble shoot this issue? I can choose an older grub version, 2.6.38-8 instead of 2.6.38-11 and this does not resolve the issue.

• Media server...serving files...............for a limited time only

  - by Craig

  I’m new to Ubuntu and am seeking help with a media server I have built. I have a couple of HTPCs in my house running XBMC. I wanted to build one for the family room working double duty as a HTPC, and media server to share movies, TV shows, music, etc. on my Windows network. So using some spare old parts I had lying around I decided to go CRAZY and build my first Linux box. I used Ubuntu because it seemed to be the most user friendly variant, especially for people that are new to Linux. I had to do a few things to get the media files shared properly on my network: Made sure my two media drives auto-mount every time I boot the computer by editing the “fstab” file – “sudo nano /etc/fstab” Installed Samba - “sudo apt-get install samba” Set a password for Samba - “sudo smbpasswd –a USERNAME” Edited the Samba configuration file to make sure the computer was in my networks workgroup – “sudo nano /etc/samba/smb.conf” In the file manager (not sure if that’s the right name for it), I right-clicked my media folders and set the sharing and permissions. The sharing was done without guest access, and permissions were set to; Owner, Group, and Others - Access: Create and Delete Files. Adjusted the Power Management settings to never put the system into sleep mode. I checked to see if I had access to the files from a Windows 7 machine and I did (Woo Hoo!). But when I tried to play any of my video files from the Windows machine (using VLC media player), they would only play for about 2-5 minutes and then they would stop with an error message saying that the file could not be accessed (Booo...). I tried playing some files through XBMC running in Windows and they worked for a bit longer (about 10-15mins), but they also stopped playing. I installed the Linux version of XBMC on the server and played the files locally with no problems. It doesn’t seem to be an issue with the files themselves, it seems to be a sharing problem on my network. So my question to the Ubuntu gurus out there is: Did I miss adding/editing something in the Samba configuration file? Did I use the right method to share my media files (file manager vs. using the terminal)? Is it possible for the computer to still go to sleep without the screen going black (does that even make sense?). Are there any special settings in Ubuntu that I should be using since this computer as a media server (is there a media server mode?...!...?). Any help on this matter would be greatly appreciated. Thanks

• Communication between state machines with hidden transitions

  - by slartibartfast

  The question emerged for me in embedded programming but I think it can be applied to quite a number of general networking situations e.g. when a communication partner fails. Assume we have an application logic (a program) running on a computer and a gadget connected to that computer via e.g. a serial interface like RS232. The gadget has a red/green/blue LED and a button which disables the LED. The LEDs color can be driven by software commands over the serial interface and the state (red/green/blue/off) is read back and causes a reaction in the application logic. Asynchronous behaviour of the application logic with regard to the LED color down to a certain delay (depending on the execution cycle of the application) is tolerated. What we essentially have is a resource (the LED) which can not be reserved and handled atomically by software because the (organic) user can at any time press the button to interfere/break the software attempt to switch the LED color. Stripping this example from its physical outfit I dare to say that we have two communicating state machines A (application logic) and G (gadget) where G executes state changes unbeknownst to A (and also the other way round, but this is not significant in our example) and only A can be modified at a reasonable price. A needs to see the reaction and state of G in one piece of information which may be (slightly) outdated but not inconsistent with respect to the short time window when this information was generated on the side of G. What I am looking for is a concise method to handle such a situation in embedded software (i.e. no layer/framework like CORBA etc. available). A programming technique which is able to map the complete behaviour of both participants on classical interfaces of a classical programming language (C in this case). To complicate matters (or rather, to generalize), a simple high frequency communication cycle of A to G and back (IOW: A is rapidly polling G) is out of focus because of technical restrictions (delay of serial com, A not always active, etc.). What I currently see as a general solution is: the application logic A as one thread of execution an adapter object (proxy) PG (presenting G inside the computer), together with the serial driver as another thread a communication object between the two (A and PG) which is transactionally safe to exchange The two execution contexts (threads) on the computer may be multi-core or just interrupt driven or tasks in an RTOS. The com object contains the following data: suspected state (written by A): effectively a member of the power set of states in G (in our case: red, green, blue, off, red_or_green, red_or_blue, red_or_off...etc.) command data (written by A): test_if_off, switch_to_red, switch_to_green, switch_to_blue operation status (written by PG): operation_pending, success, wrong_state, link_broken new state (written by PG): red, green, blue, off The idea of the com object is that A writes whichever (set of) state it thinks G is in, together with a command. (Example: suspected state="red_or_green", command: "switch_to_blue") Notice that the commands issued by A will not work if the user has switched off the LED and A needs to know this. PG will pick up such a com object and try to send the command to G, receive its answer (or a timeout) and set the operation status and new state accordingly. A will take back the oject once it is no longer at operation_pending and can react to the outcome. The com object could be separated of course (into two objects, one for each direction) but I think it is convenient in nearly all instances to have the command close to the result. I would like to have major flaws pointed out or hear an entirely different view on such a situation.

• Starting over and new to Ubuntu

  - by 2funnyyone

  We have been having repeated problems with our interent service and using windows xp & sp3 (users and premissions) I see no need for them. I started with computers long before windows. Every since sp 3 come out in 2009 I have had nothing but problems. I have lost so many computers to virius and trojans, we just stack them up. We are with Qwest/ Century link which is using advertising servers which I think is causing the problem. All the computers are networked together which is not how I set them up. I beleive Century link is networking them through assignment of a domain for our home. This causes all the computers to crash twice. This is getting expensive. We tried buying new harddrives but reinfect with hours of connecting to internet. I also beleive the modem, router and all computers are infected. I put combofix on this one and that is the only reason we are still online with this laptop. I am afraid to install new equipment because my partner and I are on SSDI and this cost a lot. I go to school at UOP and had to run off a flash and reboot this laptop to recovery every other day or so, this pass month. New plan is: We are getting ready to install new equipment but afraid to reinfect again. Need help to install new equipment. The plan is to use current internet services from Qwest/ now Century Link. The list of New equipment in order: Century link wireless modem is ZyXEL PK5000Z with 4 direct connect Ethernet ports Next Dell Optiplex 210L ( used auction purchase ) 2 gb ram 80 g hard drive Ubuntu 11.10 operating system Next Wireless D-Link router WBR-1310 with 4 direct connect Ethernet ports OK-------- Purchased Dell OEM disk for Repair or Reinstalling Windows XP Professional Operating system (2 roommates as well) All infected computers are Dell desktops or laptops with XP Pro Also purchasing Ubuntu 12.04 for 3 computers. We like the way it runs but still learning it. Questions 1] How do we fdisk the infected computers without infecting new system. We have Dos disks, but none have floppy dish drive. We do have a new floppy disk drive and usb adapter we purchased from Amazon. 2] We are thinking Avast internet security because of the boot scan. We want all software loaded before reconnecting. We can manually load our internet provider information. We purchased StopZilla $100 for 5 computers, but not sure that is what we need. But need how to setup ports security and services we will need. Really lost at this part. So we are safe when we go back on the internet. 3] Want to connect reloaded fdisk systems to router as public connection and no sharing. Do not want to network all computers. 4] Want parental/ ownership control from Ubuntu system for internet connection (Children and friends). Do we restrict at the modem and/ or router? Any help would be a blessing. I do not want to go alone on this anymore.

• How to find out console equivalents of Ubuntu System Settings GUI?

  - by user4514

  How do I in general find out, what the very nice "System Settings GUI" in Ubuntu (say 12.04) does and how to replicate the changes in command line? Many people ask questions like "how to change the keyboard rate using command line", and often the answers do not help and are hard to find. What is the easiest way to find out, what the GUI is actually changing (for various types of settings. I.e. keyboard layout, rate, mouse, network, ...)
