• Introducing the New Boot Framework in CE 7

  - by Kate Moss' Open Space

  CE 7 introduces a new boot loader framework, BLDR (platform\common\src\common\bldr\). Some people like its powerful and flexbility, others may feel its too complicate as a boot loader framework. Despite to the favor, it is already there; so let's take a look at its features. Unlike the previous BL framwork (CE7 still provides it in platform\common\src\common\boot\) is a monolithic library, the new framework has more architecture structure. It not only defines main body but also provides rich components, such as filesystem (BinFS/FAT), download transportations, display, logging and block devices: bios INT13, FAL, IDE, Flash ( and etc. Note that in the block device category, the FAL is for legacy FMD/FAL, Flash is for latest MSFlash. Some of you may have encountered MSFlash MDD/PDD compatible partition is hard to created in bootloader and now it provides a clean solution! (Since this is a big topic, I will introduce it in future post) Today, I am going to show you some basic helper components - Image Loading functions. When OS image stored in the block device, it can be a file format, says your NK.BIN in the FAT volume or a RAW format, says the image is programmed to a BINFS partition. For the first one you can use BootFileSystemReadBinFile (platform\common\src\common\bldr\fileSystem\utils\fileSystemReadBinFile.c) and use BootBlockLoadBinFsImage (platform\common\src\common\bldr\block\utils\loadBinFs.c) to load from a partition. Need a sample code? No problem, the BootLoaderLoadOs in platform\cepc\src\boot\bldr\loados.c just provide a perfect example.

• DPKG errors after upgrade to 12.10

  - by James Wulfe

  So I was doing fine then i upgraded my system to 12.10 and now i cant get my system to update all of its packages properly. no matter what i do, cleaning apt cache, manual install using dpkg, etc, i just cant get them to install. what is happening here and how do i fix this. if i would have thought 12.10 would be this much of a hassle i would have never upgraded..... here is a sampling of the code that returns from "apt-get -f install" Preparing to replace usb-modeswitch-data 20120120-0ubuntu1 (using .../usb-modeswitch-data_20120815-1_all.deb) ... /var/lib/dpkg/info/usb-modeswitch-data.prerm: 4: /var/lib/dpkg/info/usb-modeswitch-data.prerm: dpkg-maintscript-helper: Input/output error dpkg: warning: subprocess old pre-removal script returned error exit status 2 dpkg: trying script from the new package instead ... /var/lib/dpkg/tmp.ci/prerm: 4: /var/lib/dpkg/tmp.ci/prerm: dpkg-maintscript-helper: Input/output error dpkg: error processing /var/cache/apt/archives/usb-modeswitch-data_20120815-1_all.deb (--unpack): subprocess new pre-removal script returned error exit status 2 /var/lib/dpkg/info/usb-modeswitch-data.postinst: 7: /var/lib/dpkg/info/usb-modeswitch-data.postinst: dpkg-maintscript-helper: Input/output error dpkg: error while cleaning up: subprocess installed post-installation script returned error exit status 2 Errors were encountered while processing: /var/cache/apt/archives/network-manager_0.9.6.0-0ubuntu7_i386.deb /var/cache/apt/archives/pcmciautils_018-8_i386.deb /var/cache/apt/archives/unity-common_6.10.0-0ubuntu2_all.deb /var/cache/apt/archives/whoopsie_0.2.7_i386.deb /var/cache/apt/archives/usb-modeswitch_1.2.3+repack0-1ubuntu3_i386.deb /var/cache/apt/archives/usb-modeswitch-data_20120815-1_all.deb E: Sub-process /usr/bin/dpkg returned an error code (1) It is also just these 6 packages only. no other packages have given me this kind of trouble. well i should say as of now. It was just 5, but them i got an update for unity, and now unity-common is added to the trouble makers. which prevents me from further upgrading the actual unity package as this package is a dependancy.....

• Launching php script through comman line - keeping terminal window open after execution

  - by somethis

  Oh, my girlfriend really likes it when I launch php scripts! There's something special about them, she says ... Thus, I coded this script to run throught the CLI (Command Line Interface) - so it's running locally, not on a web server. It launches just fine through right click open run in terminal but closes right after execution. **Is there a way to keep the terminal window open? Of course I can launch it through a terminal window - which would stay open - but I'm looking for a one click action. With bash scripts I use $SHELL but that didn't work (see code below). So far, the only thing I came up with is sleep(10); which gives me 10 seconds for my girl to check the output. I'd rather close the terminal window manually, though. #!/usr/bin/php -q <?php echo "Hello World \n"; # wait before closing terminal window sleep(10); # the following line doesn't work $SHELL; ?> (PHP 5.4.6-1ubuntu1.2 (cli) (built: Mar 11 2013 14:57:54) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies )

• Ubuntu 12.04 stopped recognizing my BenQ monitor and reduced resolution to 1024x768

  - by Omri

  A few days ago I installed Ubuntu 12.04 32bit Desktop. It recognized my hardware without a problem (at least that I know of) and all worked fine. I left my system running (it is at work) through the night because it is also working as a database server and when I came today to work the resolution was 1024x768 (the monitor recommends 1920x1080) even though in the Display section of the System Settings it was recognized as BenQ, and no higher resolution was offered. After a restart, the monitor name changed from BenQ to Unknown. This is a desktop computer. I also installed gtk-redshift and f.lux. I checked Additional Drivers to see if there is something I can install but it didn't find anything. I tried to Google it but I didn't find anything about a monitor stopping being recognized after it was already working. I did enable some PPAs yesterday, namely webupd8, mozillateam/thunderbird-stable and some other, and I also followed the instructions to patch the NotifyOSD to be more friendly: sudo add-apt-repository ppa:caffeine-developers/ppa sudo add-apt-repository ppa:leolik/leolik sudo apt-get update sudo apt-get upgrade sudo apt-get install libnotify-bin pkill notify-osd sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install notifyosdconfig I now purged both caffeine-developers and leolik PPAs in the hope it will help, but no change. Has there been a change in the packages that could introduce this problem? Any help will be very appreciated :-) Omri

• Finding shapes in 2D Array, then optimising

  - by assemblism

  I'm new so I can't do an image, but below is a diagram for a game I am working on, moving bricks into patterns, and I currently have my code checking for rotated instances of a "T" shape of any colour. The X and O blocks would be the same colour, and my last batch of code would find the "T" shape where the X's are, but what I wanted was more like the second diagram, with two "T"s Current result      Desired Result [X][O][O]                [1][1][1] [X][X][_]                [2][1][_] [X][O][_]                [2][2][_] [O][_][_]                [2][_][_] My code loops through x/y, marks blocks as used, rotates the shape, repeats, changes colour, repeats. I have started trying to fix this checking with great trepidation. The current idea is to: loop through the grid and make note of all pattern occurrences (NOT marking blocks as used), and putting these to an array loop through the grid again, this time noting which blocks are occupied by which patterns, and therefore which are occupied by multiple patterns. looping through the grid again, this time noting which patterns obstruct which patterns That much feels right... What do I do now? I think I would have to try various combinations of conflicting shapes, starting with those that obstruct the most other patterns first.How do I approach this one? use the rational that says I have 3 conflicting shapes occupying 8 blocks, and the shapes are 4 blocks each, therefore I can only have a maximum of two shapes. (I also intend to incorporate other shapes, and there will probably be score weighting which will need to be considered when going through the conflicting shapes, but that can be another day) I don't think it's a bin packing problem, but I'm not sure what to look for. Hope that makes sense, thanks for your help

• De-index URL paremeters

  - by Doug Firr

  Upon reading over this question is lengthy so allow me to provide a one sentence summary: I need to get Google to de-index URLs that have certain parameters appended I have a website example.com with language translations. There used to be many translations but I deleted them all so that only English (Default) and French options remain. When one selects a language option a parameter is aded to the URL. For example, the home page: https://example.com (default) https://example.com/main?l=fr_FR (French) I added a robots.txt to stop Google from crawling any of the language translations: # robots.txt generated at http://www.mcanerin.com User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /*?l= So any pages containing "?l=" should not be crawled. I checked in GWT using the robots testing tool. It works. But under html improvements the previously crawled language translation URLs remain indexed. The internet says to add a 404 to the header of the removed URLs so the Googles knows to de-index it. I checked to see what my CMS would throw up if I visited one of the URLs that should no longer exist. This URL was listed in GWT under duplicate title tags (One of the reasons I want to scrub up my URLS) https://example.com/reports/view/884?l=vi_VN&l=hy_AM This URL should not exist - I removed the language translations. The page loads when it should not! I played around. I typed example.com?whatever123 It seems that parameters always load as long as everything before the question mark is a real URL. So if Google has indexed all these URLS with parameters how do I remove them? I cannot check if a 404 is being generated because the page always loads because it's a parameter that needs to be de-indexed.

• Custom daemon script: works, but does not run at boot / startup

  - by pearjoint

  this is Ubuntu 10.10 Maverick. I have the following shell script in init.d that I want to run as a "daemon" (background service with start/stop/restart really) at system startup. There is a symlink in rc3.d. I tried 4 and 5 too. (Ideally this would initialize before graphical login happens and before a user logs in.) IMPORTANT: the script works 100% as expected and required when testing this with service MetaLeapDaemon start and service MetaLeapDaemon stop. (This shell script calls a Python program which makes sure the appropriate .pid files are both created at startup and deleted at exit.) So generally it works fine but now my only issue is why it will not be run at any of the run-levels I tried. I know for sure it isn't run because the log file it normally creates does not get created. As you can see (by the lack of any uid:gid args in the start-stop-daemon commands) this would currently run only under root, is this forbidden in a default setup? Here's the script, pretty much your run-off-the-mill daemon script really: #! /bin/sh DAEMON=/opt/metaleap/_core/daemon/MetaLeapDaemon.py NAME=MetaLeapDaemon DESC="MetaLeapDaemon" test -f $DAEMON || exit 0 set -e case "$1" in start) start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; stop) start-stop-daemon --stop --pidfile /var/run/$NAME.pid ;; restart) start-stop-daemon --stop --pidfile /var/run/$NAME.pid sleep 1 start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; *) N=/etc/init.d/$NAME echo "Usage: $N {start|stop|restart}" >&2 exit 1 ;; esac exit 0

• How to read default key value with dconf or gsettings?

  - by Zta

  I would like to know the default value of a dconf/gsettings key. My question is a followup of the question below: Where can I get a list of SCHEMA / PATH / KEY to use with gsettings? What I'm trying to do, so create a script that reads all my personal preferences so I can back them up and restore them. I plan to iterate though all keys, like the script above, see what keys have been changed from their default value, and make a note of these, that can be restored later. I see that the dconf-editor display the keys' default value, but I'd very much like to script this. Also, I don't see how parsing the schemas /usr/share/glib-2.0/schemas/ can be automated. Maybe someone can help? gsettings get-default|list-defaults would be nice =) (Geesh, it was much easier in the old days where you just kept your ~/.somethingrc in subversion ... =\ Based on the answer given below, I've updated the script to print schema, key, key's data type, default value, and actual value: #!/bin/bash for schema in $(gsettings list-schemas | sort); do for key in $(gsettings list-keys $schema | sort); do type="$(gsettings range $schema $key | tr "\n" " ")" default="$(XDG_CONFIG_HOME=/tmp/ gsettings get $schema $key | tr "\n" " ")" value="$(gsettings get $schema $key | tr "\n" " ")" echo "$schema :: $key :: $type :: $default :: $value" done done This workaround basically covers what I need. I'll continue working on the backup scrip from here.

• No boot or grub file after using ls command

  - by Poke Moke

  I had xubuntu installed, i believe version 12.04 and then tried to dual boot with backbox. It worked from the flash drive but upon installing it onto the hard drive, I could no longer boot backbox. I decided I would just clear my OS and put just backbox on the hard drive and only have a single boot. To do this, I erased my boot file completely which led to my current position. I am put into the grub rescue prompt. I can't do a system restore, I can't boot with anything I might try including puppy linux and a boot rescue, and I've looked up the commands and I've tried to fix this. I can do ls, I find the correct hd but then I'm stuck as I don't have a boot or grub folder. The command is typed as: ls (hd1,msdos1)/ and listed is ./ ../ lost+found/ etc/ media/ bin/ dev/ home/ lib/ mnt/ opt/ proc/ root/ run/ sbin/ selinux/ srv/ sys/ tmp/ usr/ var/ initrd.img vmlinuz cdrom/ apfolder initrd.img.old vmlinuz.old (not sure if it's initrd or init rd.img. as it wraps around the screen there.) I've seen commands regarding boot or grub if they are seen but as listed, they aren't there. Any ideas?

• sqlplus: Running "set lines" and "set pagesize" automatially

  - by katsumii

  This is a followup to my previous entry. Using the full tty real estate with sqlplus (INOUE Katsumi @ Tokyo) 'rlwrap' is widely used for adding 'sqlplus' the history function and command line editing. Here's another but again kludgy implementation. First this is the alias. alias sqlplus="rlwrap -z ~/sqlplus.filter sqlplus" And this is the file content. #!/usr/bin/env perl use lib ($ENV{RLWRAP_FILTERDIR} or "."); use RlwrapFilter; use POSIX qw(:signal_h); use strict; my $filter = new RlwrapFilter; $filter -> prompt_handler(\&prompt); sigprocmask(SIG_UNBLOCK, POSIX::SigSet->new(28)); $SIG{WINCH} = 'winchHandler'; $filter -> run; sub winchHandler { $filter -> input_handler(\&input); sigprocmask(SIG_UNBLOCK, POSIX::SigSet->new(28)); $SIG{WINCH} = 'winchHandler'; $filter -> run; } sub input { $filter -> input_handler(undef); return `resize |sed -n "1s/COLUMNS=/set linesize /p;2s/LINES=/set pagesize /p"` . $_; } sub prompt { if ($_ =~ "SQL> ") { $filter -> input_handler(\&input); $filter -> prompt_handler(undef); } return $_; } I hope I can compare these 2 implementations after testing more and getting some feedbacks.

• Transmission shutdown script for multiple torrents?

  I have written a shutdown script for transmission. Transmission calls the script after a torrent download finishes. The script runs perfectly on my machine (Ubuntu 11.04 & 12.04). #!/bin/bash sleep 300s # default display on current host DISPLAY=:0.0 # find out if monitor is on. Default timeout can be configured from screensaver/Power configuration. STATUS=`xset -display $DISPLAY -q | grep 'Monitor'` echo $STATUS if [ "$STATUS" == " Monitor is On" ] ### Then check if its still downloading a torrent. Couldn't figure out how.(May be) by monitoring network downstream activity? then notify-send "Downloads Complete" "Exiting transmisssion now" pkill transmission else notify-send "Downloads Complete" "Shutting Down Computer" dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown fi exit 0 The problem is that when I'm downloading more than one file, when the first one finishes, transmission executes the script. I would like to do that but after all downloads are completed. I want to put a 2nd check ( right after monitor check) if it is still downloading another torrent. Is there any way to do this?

• Adding SPF records in GoDaddy

  - by Mayank swami

  I have the GoDaddy hosting and send mail using the following code: $to = "[email protected]"; $subject = "Test mail"; $message = "Hello! This is a simple email message."; $from = "[email protected]"; $headers = "From:" . $from; mail($to,$subject,$message,$headers); echo "Mail Sent."; When the mail arrives at its destination I see the following (in red outline) I don't want to show the "via server" and for that there is an option to add a SPF record. To do this I have followed the instructions in this page: Managing DNS for Your Domain Names but it's not working. After that i have tried: v=spf1 include:_spf.google.com ~all as described in http://support.google.com/a/bin/answer.py?hl=en&answer=178723 but I still get the same result. How can I solve this and prevent "via server" showing?

• Mod a Swing Arm Lamp into an Adjustable Camera Stand

  - by Jason Fitzpatrick

  If you’re looking for a simple way to get a bird’s eye view to record your DIY projects or other table-based activities like gaming or tinkering, this simple modification to a swing-arm lamp offers a highly flexible camera mount on the cheap. IKEAHacker reader Stef needed an adjustable arm for his iPhone camera so he could record in a top-down-view for some drawing tutorials he was working on. Rather than shell out big bucks for a custom boom arm, he scrounged up a swing arm lamp with a broken shade in the as-is bin at his local IKEA. To mount the iPhone he simply attached a car mount for the iPhone to the swing arm and called it good. Hit up the link below for more pictures; even if you don’t have an IKEA nearby, swing arm lamps are cheap and easy to acquire.

  I seem to be having problems using vmbuilder with a local https mirror "--mirror=https:///archive.ubuntu.com/ubuntu/" as shown below: Process (['/usr/sbin/debootstrap', '--arch=amd64', 'precise', '/tmp/tmpYc0cOktmpfs', '<my_internal_server>/ubuntu/']) returned 1. stdout: I: Retrieving Release E: Failed getting release file <my_internal_server>/ubuntu/dists/precise/Release , stderr: 2012-10-18 10:36:36,429 INFO : Unmounting tmpfs from /tmp/tmpYc0cOktmpfs Traceback (most recent call last): File "/usr/bin/vmbuilder", line 24, in <module> cli.main() File "/usr/lib/python2.7/dist-packages/VMBuilder/contrib/cli.py", line 216, in main distro.build_chroot() File "/usr/lib/python2.7/dist-packages/VMBuilder/distro.py", line 83, in build_chroot self.call_hooks('bootstrap') File "/usr/lib/python2.7/dist-packages/VMBuilder/distro.py", line 67, in call_hooks call_hooks(self, *args, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/util.py", line 165, in call_hooks getattr(context, func, log_no_such_method)(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/plugins/ubuntu/distro.py", line 136, in bootstrap self.suite.debootstrap() File "/usr/lib/python2.7/dist-packages/VMBuilder/plugins/ubuntu/dapper.py", line 269, in debootstrap run_cmd(*cmd, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/util.py", line 120, in run_cmd raise VMBuilderException, "Process (%s) returned %d. stdout: %s, stderr: %s" % (args.__repr__(), status, mystdout.buf, mystderr.buf) VMBuilder.exception.VMBuilderException: Process (['/usr/sbin/debootstrap', '--arch=amd64', 'precise', '/tmp/tmpYc0cOktmpfs', '<my_internal_server>/ubuntu/']) returned 1. stdout: I: Retrieving Release E: Failed getting release file <my_internal_server>/ubuntu/dists/precise/Release , stderr: I've checked that the files are in the correct place and i'm able to setup this using http instead of https. However this server will be providing https access only to the repos, the http is only temporarily open. This might be due to the certificate not being valid on the https (since it's self signed) or due to the fact that vmbuilder doesn't support https? In either case how can i get this to work? (If it's the case of the invalid certificate I don't mind ignoring any checks)

• What is bondib1 used for on SPARC SuperCluster with InfiniBand, Solaris 11 networking & Oracle RAC?

  - by user12620111

  A co-worker asked the following question about a SPARC SuperCluster InfiniBand network: > on the database nodes the RAC nodes communicate over the cluster_interconnect. This is the > 192.168.10.0 network on bondib0. (according to ./crs/install/crsconfig_params NETWORKS> setting) > What is bondib1 used for? Is it a HA counterpart in case bondib0 dies?
