  • Rails noob - How to work on data stored in models

    - by Raghav Kanwal
    I'm a beginner to Ruby and Rails, and I have made a couple applications like a Microposts clone and a Todo-List for starters, but I'm starting work on another project. I've got 2 models - user and tracker, you log in via the username which is authenticated and you can log down data which is stored in the tracker table. The tracker has a column named "Calories" and I would like Rails to sum all of the values entered if they are on the same date, and output the result which is subtracted from, say 3000 in a new statement after the display of the model. I know what I'm talking about is just ruby code, im just not sure how to incorporate it. :( Could someone please guide me through this? And also link me to some guides/tutorials which teach working on data from models? Thank you :)

  • How to install older ruby version on ubuntu Precise Pangolin?

    - by Codestudent
    I got a present: older Rails tutorials that needs old ruby version. I try to install ruby-1.8 with the packet manager. I still got problems with the tutorial example code. Next I try rvm to install the old ruby version. Unfortunately I got an error. I do not know what to do. I search the internet. Many people got no problems with rvm. rvm use *ERROR: Branch origin/ruby_1_8_4 not found.* and *ERROR: Error running 'GEM_PATH="/usr/share/ruby-rvm/gems/ruby-1.8.4- tv1_8_4:/usr/share/ruby-rvm/gems/ruby-1.8.4-tv1_8_4@global:/usr/share/ruby- rvm/gems/ruby-1.8.4-tv1_8_4:/usr/share/ruby-rvm/gems/ruby-1.8.4-tv1_8_4@global" GEM_HOME="/usr/share/ruby-rvm/gems/ruby-1.8.4-tv1_8_4" "/usr/share/ruby- rvm/rubies/ruby-1.8.4-tv1_8_4/bin/ruby" "/usr/share/ruby-rvm/src/rubygems- 1.3.7/setup.rb"', please read /usr/share/ruby-rvm/log/ruby-1.8.4- tv1_8_4/rubygems.install.log* Please give me a hint.

  • Performing a clean database creation using msbuild

    - by Robert May
    So I’m taking a break from writing about other Agile stuff for a post. :)  I’m still going to get back to the other subjects, but this is fun too. Something I’ve done quite a bit of is MSBuild and CI work.  I’m experimenting with ways to improve what I’ve done in the past, particularly around database CI. Today, I developed a mechanism for starting from scratch with your database.  By scratch, I mean blowing away the existing database and creating it again from a single command line call.  I’m a firm believer that developers should be able to get to a known clean state at the database level with a single command and that they should be operating off of their own isolated database to improve productivity.  These scripts will help that. Here’s how I did it.  First, we have to disconnect users.  I did so using the help of a script from sql server central.  Note that I’m using sqlcmd variable replacement. -- kills all the users in a particular database -- dlhatheway/3M, 11-Jun-2000 declare @arg_dbname sysname declare @a_spid smallint declare @msg varchar(255) declare @a_dbid int set @arg_dbname = '$(DatabaseName)' select @a_dbid = sdb.dbid from master..sysdatabases sdb where sdb.name = @arg_dbname declare db_users insensitive cursor for select sp.spid from master..sysprocesses sp where sp.dbid = @a_dbid open db_users fetch next from db_users into @a_spid while @@fetch_status = 0 begin select @msg = 'kill '+convert(char(5),@a_spid) print @msg execute (@msg) fetch next from db_users into @a_spid end close db_users deallocate db_users GO Once all users are booted from the database, we can commence with recreating the database.  I generated the script that is used to create a database from SQL Server management studio, so I’m only going to show the bits that weren’t generated that are important.  There are a bunch of Alter Database statements that aren’t shown. First, I had to find the default location of the database files in the install, since they can be in many different locations.  I used Method 1 from a technet blog and then modified it a bit to do what I needed to do.  I ended up using dynamic SQL because for the life of me, I couldn’t get the “Filename” property to not return an error when I used anything besides a string.  I’m dropping the database first, if it exists.  Here’s the code:   IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = N'$(DatabaseName)') BEGIN drop database $(DatabaseName) END; go IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = 'zzTempDBForDefaultPath') BEGIN DROP DATABASE zzTempDBForDefaultPath END; -- Create temp database. Because no options are given, the default data and --- log path locations are used CREATE DATABASE zzTempDBForDefaultPath; DECLARE @Default_Data_Path VARCHAR(512), @Default_Log_Path VARCHAR(512); --Get the default data path SELECT @Default_Data_Path = ( SELECT LEFT(physical_name,LEN(physical_name)-CHARINDEX('\',REVERSE(physical_name))+1) FROM sys.master_files mf INNER JOIN sys.[databases] d ON mf.[database_id] = d.[database_id] WHERE d.[name] = 'zzTempDBForDefaultPath' AND type = 0); --Get the default Log path SELECT @Default_Log_Path = ( SELECT LEFT(physical_name,LEN(physical_name)-CHARINDEX('\',REVERSE(physical_name))+1) FROM sys.master_files mf INNER JOIN sys.[databases] d ON mf.[database_id] = d.[database_id] WHERE d.[name] = 'zzTempDBForDefaultPath' AND type = 1); --Clean up. IF EXISTS(SELECT 1 FROM [master].[sys].[databases] WHERE [name] = 'zzTempDBForDefaultPath') BEGIN DROP DATABASE zzTempDBForDefaultPath END; DECLARE @SQL nvarchar(max) SET @SQL= 'CREATE DATABASE $(DatabaseName) ON PRIMARY ( NAME = N''$(DatabaseName)'', FILENAME = N''' + @Default_Data_Path + N'$(DatabaseName)' + '.mdf' + ''', SIZE = 2048KB , FILEGROWTH = 1024KB ) LOG ON ( NAME = N''$(DatabaseName)Log'', FILENAME = N''' + @Default_Log_Path + N'$(DatabaseName)' + '.ldf' + ''', SIZE = 1024KB , FILEGROWTH = 10%) ' exec (@SQL) GO And with that, your database is created.  You can run these scripts on any server and on any database name.  To do that, I created an MSBuild script that looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="4.0"> <PropertyGroup> <DatabaseName>MyDatabase</DatabaseName> <Server>localhost</Server> <SqlCmd>sqlcmd -v DatabaseName=$(DatabaseName) -S $(Server) -i </SqlCmd> <ScriptDirectory>.\Scripts</ScriptDirectory> </PropertyGroup> <Target Name ="Rebuild"> <ItemGroup> <ScriptFiles Include="$(ScriptDirectory)\*.sql"/> </ItemGroup> <Exec Command="$(SqlCmd) &quot;%(ScriptFiles.Identity)&quot;" ContinueOnError="false"/> </Target> </Project> Note that the Scripts directory is underneath the directory where I’m running the msbuild command and is relative to that directory.  Note also that the target is using batching to run each script in the scripts subdirectory, one after the other.  Each script is passed to the sqlcmd command line execution using the .Identity property on the itemgroup that is created.  This target file is saved in the file “Database.target”. To make this work, you’ll need msbuild in your path, and then run the following command: msbuild database.target /target:Rebuild Once you’ve got your virgin database setup, you’d then need to use a tool like dbdeploy.net to determine that it was a virgin database, build a change script based on the change scripts, and then you’d want another sqlcmd call to update the database with the appropriate scripts.  I’m doing that next, so I’ll post a blog update when I’ve got it working.

  • 500 Internal Server Error with PHP application

    - by James
    I have written a PHP application using Windows and XAMPP. I've been trying to run it on Ubuntu 10.10 with Lighttpd 1.4.26.

  • Announcing MySQL Enterprise Backup 3.7.1

    - by Hema Sridharan
    The MySQL Enterprise Backup (MEB) Team is pleased to announce the release of MEB 3.7.1, a maintenance release version that includes bug fixes and enhancements to some of the existing features. The most important feature introduced in this release is Automatic Incremental Backup. The new  argument syntax for the --incremental-base option is introduced which makes it simpler to perform automatic incremental backups. When the options --incremental & --incremental-base=history:last_backup are combined, the mysqlbackup command  uses the metadata in the mysql.backup_history table to determine the LSN to use as the lower limit of the incremental backup. You no longer need to keep track of the actual LSN (as in the option --start-lsn=LSN) or even the location of the previous backup (as in the option --incremental-base=dir:directory_path)This release also incudes various bug fixes related to some options used in MEB. The most important are few of them as listed below,1. The option --force now allows overwriting InnoDB data and log files in  combination with the apply-log and apply-incremental-backup options, and replacing the image file in combination with the backup-to-image and backup-dir-to-image options. 2. Resolved a bug that prevented MEB to interface with third-party storage managers to execute backup and restore jobs in combination with the SBT interface and associated --sbt* options for mysqlbackup. 3. When MEB is run with the copy-back option,  it now displays warnings as existing files are overwritten.For more information about other bug fixes, please refer to the change-log in http://dev.mysql.com/doc/mysql-enterprise-backup/3.7/en/meb-news.html The complete MEB documentation is located at http://dev.mysql.com/doc/mysql-enterprise-backup/3.7/en/index.html. You will find the binaries for the new release in My Oracle Support,  https://support.oracle.comChoose the "Patches & Updates" tab, and then use the "Product or Family (Advanced Search)" feature. If you haven't looked at MEB 3.7.1 recently, please do so now and let us know how MEB works for you. Send your feedback to [email protected].

  • Debugging "Premature end of script headers" - WSGI/Django [migrated]

    - by Marcin
    I have recently deployed an app to a shared host (webfaction), and for no apparent reason, my site will not load at all (it worked until today). It is a django app, but the django.log is not even created; the only clue is that in one of the logs, I get the error message: "Premature end of script headers", identifying my wsgi file as the source. I've tried to add logging to my wsgi file, but I can't find any log created for it. Is there any recommended way to debug this error? I am on the point of tearing my hair out. My WSGI file: import os import sys from django.core.handlers.wsgi import WSGIHandler import logging logger = logging.getLogger(__name__) os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' os.environ['CELERY_LOADER'] = 'django' virtenv = os.path.expanduser("~/webapps/django/oneclickcosvirt/") activate_this = virtenv + "bin/activate_this.py" execfile(activate_this, dict(__file__=activate_this)) # if 'VIRTUAL_ENV' not in os.environ: # os.environ['VIRTUAL_ENV'] = virtenv sys.path.append(os.path.dirname(virtenv+'oneclickcos/')) logger.debug('About to run WSGIHandler') try: application = WSGIHandler() except (Exception,), e: logger.debug('Exception starting wsgihandler: %s' % e) raise e

  • Varnish 3.0.2 to Apache2 sometimes return error 503

    - by Ronnie Jespersen
    Hey guys I hope you can help me out here. I have an Ngingx parsing http and https to a varnish cache(3.0.2). From the varnish it is sent to apache2. Now I have for some time been tracking some strange 503 errors. But I cant seem to find the silver bullet. Currently I am logging the 503 errors through varnish this way: sudo varnishlog -c -m TxStatus:503 >> /home/rj/varnishlog503.log and then referring to the apache access log to see if any 503 requests have been handled. Today I had a health check from the firewall that failed: 20 SessionOpen c 127.0.0.1 34319 :8081 20 ReqStart c 127.0.0.1 34319 607335635 20 RxRequest c HEAD 20 RxURL c /health-check 20 RxProtocol c HTTP/1.0 20 RxHeader c X-Real-IP: 192.168.3.254 20 RxHeader c Host: 192.168.3.189 20 RxHeader c X-Forwarded-For: 192.168.3.254 20 RxHeader c Connection: close 20 RxHeader c User-Agent: Astaro Service Monitor 0.9 20 RxHeader c Accept: */* 20 VCL_call c recv lookup 20 VCL_call c hash 20 Hash c /health-check 20 VCL_return c hash 20 VCL_call c miss fetch 20 Backend c 33 aurum aurum 20 FetchError c http first read error: -1 11 (No error recorded) 20 VCL_call c error deliver 20 VCL_call c deliver deliver 20 TxProtocol c HTTP/1.1 20 TxStatus c 503 20 TxResponse c Service Unavailable 20 TxHeader c Server: Varnish 20 TxHeader c Content-Type: text/html; charset=utf-8 20 TxHeader c Retry-After: 5 20 TxHeader c Content-Length: 879 20 TxHeader c Accept-Ranges: bytes 20 TxHeader c Date: Wed, 06 Jun 2012 12:35:12 GMT 20 TxHeader c X-Varnish: 607335635 20 TxHeader c Age: 60 20 TxHeader c Via: 1.1 varnish 20 TxHeader c Connection: close 20 Length c 879 20 ReqEnd c 607335635 1338986052.649786949 1338986112.648169994 0.000160217 59.997980356 0.000402689 Now the backend server (apache) does not have any 503 error in the access log at this point. So I am confused. Is this varnish throwing a 503 because it thinks apache is to slow? There is a lot traffic coming through at this point so I know the server is up and running. I do have other 503 error codes with posts and gets so there is really no pattern. It seems to be at random times and random requests. Even in the morning when the server dosen't seem to be doing anything. I do see another pattern in the log: 4 VCL_call c recv pass 4 VCL_call c hash 4 Hash c /?id=412 4 VCL_return c hash 4 VCL_call c pass pass 4 FetchError c no backend connection 4 VCL_call c error deliver 4 VCL_call c deliver deliver Here fetcherror says "no backend connection". A summery of the FetchErrors in todays log: 16 FetchError c http first read error: -1 11 (No error recorded) 5 FetchError c http first read error: -1 11 (No error recorded) 4 FetchError c http first read error: -1 11 (No error recorded) 19 FetchError c http first read error: -1 11 (No error recorded) 5 FetchError c http first read error: -1 11 (No error recorded) 23 FetchError c http first read error: -1 11 (No error recorded) 24 FetchError c http first read error: -1 11 (No error recorded) 16 FetchError c http first read error: -1 11 (No error recorded) 6 FetchError c http first read error: -1 11 (No error recorded) 4 FetchError c http first read error: -1 11 (No error recorded) 5 FetchError c http first read error: -1 11 (No error recorded) 4 FetchError c http first read error: -1 11 (No error recorded) 4 FetchError c http first read error: -1 11 (No error recorded) 22 FetchError c http first read error: -1 11 (No error recorded) 6 FetchError c http first read error: -1 11 (No error recorded) 21 FetchError c http first read error: -1 11 (No error recorded) 26 FetchError c no backend connection 4 FetchError c no backend connection 20 FetchError c http first read error: -1 11 (No error recorded) 39 FetchError c http first read error: -1 11 (No error recorded) I haven't changed the default timeout values for varnish.

  • Still no keyboard after uninstalling Ubuntu

    - by Muhammad Rushdi Ibrahim
    I installed Ubuntu 11.04 for the first time yesterday. After rebooting for the first time, I couldn't log in because I couldn't type anything using the keyboard. After rebooting, the keyboard failed completely; I can only automatically boot into Windows since I can't choose Ubuntu. Then the problem got worse. I had to use On-Screen keyboard to log in into Windows. Still no keyboard. When I rebooted, my laptop couldn't reboot at all! I had to hard reboot. I decided to uninstall the Ubuntu, using the Add/Remove program in the Control Panel. I uninstalled it successfully. My laptop automatically boots into Windows without Ubuntu option. However, I still don't have the keyboard! Please help me. Acer Aspire 4935 Windows 7 Ultimate Thanks.

  • Ubuntu One using 500 MB memory also when idle

    - by cdysthe
    I'm a Dropbox convert (I hope!), but after having used Ubuntu One for a couple of weeks I notice a few differences from Dropbox. The most glaring difference is that the sync daemon constantly takes 500MB ram on my system (Ubuntu 12.04 x64). It hogs this amount of memory as soon as I log in, does it's initial sync/check but keeps the memory. All in all it seems to me that Ubuntu One uses more system resources than Dropbox. I am syncing the same folders and files with Ubuntu One as I was with Dropbox. Also, afte I log in Ubuntu One grids at 100% CPU for at least five minutes which can be annoying on a laptop, but is not a showstopper. I'm wondering if this is a problem on my system, or if Ubuntu One is expected to use that amount of memory even when idle?

  • What is the current state of Ubuntu's transition from init scripts to Upstart?

    - by Adam Eberlin
    What is the current state of Ubuntu's transition from init.d scripts to upstart? I was curious, so I compared the contents of /etc/init.d/ to /etc/init/ on one of our development machines, which is running Ubuntu 12.04 LTS Server. # /etc/init.d/ # /etc/init/ acpid acpid.conf apache2 --------------------------- apparmor --------------------------- apport apport.conf atd atd.conf bind9 --------------------------- bootlogd --------------------------- cgroup-lite cgroup-lite.conf --------------------------- console.conf console-setup console-setup.conf --------------------------- container-detect.conf --------------------------- control-alt-delete.conf cron cron.conf dbus dbus.conf dmesg dmesg.conf dns-clean --------------------------- friendly-recovery --------------------------- --------------------------- failsafe.conf --------------------------- flush-early-job-log.conf --------------------------- friendly-recovery.conf grub-common --------------------------- halt --------------------------- hostname hostname.conf hwclock hwclock.conf hwclock-save hwclock-save.conf irqbalance irqbalance.conf killprocs --------------------------- lxc lxc.conf lxc-net lxc-net.conf module-init-tools module-init-tools.conf --------------------------- mountall.conf --------------------------- mountall-net.conf --------------------------- mountall-reboot.conf --------------------------- mountall-shell.conf --------------------------- mounted-debugfs.conf --------------------------- mounted-dev.conf --------------------------- mounted-proc.conf --------------------------- mounted-run.conf --------------------------- mounted-tmp.conf --------------------------- mounted-var.conf networking networking.conf network-interface network-interface.conf network-interface-container network-interface-container.conf network-interface-security network-interface-security.conf newrelic-sysmond --------------------------- ondemand --------------------------- plymouth plymouth.conf plymouth-log plymouth-log.conf plymouth-splash plymouth-splash.conf plymouth-stop plymouth-stop.conf plymouth-upstart-bridge plymouth-upstart-bridge.conf postgresql --------------------------- pppd-dns --------------------------- procps procps.conf rc rc.conf rc.local --------------------------- rcS rcS.conf --------------------------- rc-sysinit.conf reboot --------------------------- resolvconf resolvconf.conf rsync --------------------------- rsyslog rsyslog.conf screen-cleanup screen-cleanup.conf sendsigs --------------------------- setvtrgb setvtrgb.conf --------------------------- shutdown.conf single --------------------------- skeleton --------------------------- ssh ssh.conf stop-bootlogd --------------------------- stop-bootlogd-single --------------------------- sudo --------------------------- --------------------------- tty1.conf --------------------------- tty2.conf --------------------------- tty3.conf --------------------------- tty4.conf --------------------------- tty5.conf --------------------------- tty6.conf udev udev.conf udev-fallback-graphics udev-fallback-graphics.conf udev-finish udev-finish.conf udevmonitor udevmonitor.conf udevtrigger udevtrigger.conf ufw ufw.conf umountfs --------------------------- umountnfs.sh --------------------------- umountroot --------------------------- --------------------------- upstart-socket-bridge.conf --------------------------- upstart-udev-bridge.conf urandom --------------------------- --------------------------- ureadahead.conf --------------------------- ureadahead-other.conf --------------------------- wait-for-state.conf whoopsie whoopsie.conf To be honest, I'm not entirely sure if I'm interpreting the division of responsibilities properly, as I didn't expect to see any overlap (of what framework handles which services). So I was quite surprised to learn that there was a significant amount of overlap in service references, in addition to being unable to discern which of the two was intended to be the primary service framework. Why does there seem to be a fair amount of redundancy in individual service handling between init.d and upstart? Is something else at play here that I'm missing? What is preventing upstart from completely taking over for init.d? Is there some functionality that certain daemons require which upstart does not yet have, which are preventing some services from converting? Or is it something else entirely?

  • Apache 2.4 PHP 5.4 mysql not found?

    - by jurchiks
    Just tried setting up the latest Apache (2.4.1 x86 VC10 from apachelounge) and PHP (5.4 VC9 TS X86, with the php5apache2_4.dll) on my PC and ran into this weird problem; in my php.ini I have enabled all of the following: extension=php_mysql.dll extension=php_mysqli.dll extension=php_pdo_mysql.dll but when I try to print the available PDO's using this: print_r(PDO::getAvailableDrivers()); It gives me an empty array. PhpMyAdmin and MantisBT also refuse to work, saying that the mysql extension is missing. phpinfo() gives this: PDO PDO support enabled PDO drivers no value and when searching for mysql, only the mysqlnd section pops up... The DLLs are there in the D:/php/ext folder and no errors pop up when starting up Apache, as well as no errors in the Windows Event Log, and PHP itself has no error log anyway. What could possibly be the problem with this? Before this I had Apache 2.2.22 from apachelounge and PHP 5.3.9 and I had no problems. Now nothing works...

  • SQL SERVER – Creating All New Database with Full Recovery Model

    - by pinaldave
    Sometimes, complex problems have very simple solutions. Let us see the following email which I received recently. “Hi Pinal, In our system when we create new database, by default, they are all created with the Simple Recovery Model. We have to manually change the recovery model after we create the database. We used the following simple T-SQL code: CREATE DATABASE dbname. We are very frustrated with this situation. We want all our databases to have the Full Recovery Model option by default. We are considering the following methods; please suggest the most efficient one among them. 1) Creating a Policy; when it is violated, the database model can be fixed 2) Triggers at Server Level 3) Automated Job which goes through all the databases and checks their recovery model; if the DBA has not changed the model, then the job will list the Databases and change their recovery model Also, we have a situation where we need a database in the Simple Recovery Model as well – how to white list them? Please suggest the best method.” Indeed, an interesting email! The answer to their question, i.e., which is the best method to fit their needs (white list, default, etc)? It will be NONE of the above. Here is the solution in one line and also the easiest way: Just go to your Model database: Path in SSMS >> Databases > System Databases >> model >> Right Click Properties >> Options >> Recovery Model - Select Full from dropdown. Every newly created database takes its base template from the Model Database. If you create a custom SP in the Model Database, when you create a new database, it will automatically exist in that database. Any database that was already created before making changes in the Model Database will not be affected at all. Creating Policy is also a good method, and I will blog about this in a separate blog post, but looking at current specifications of the reader, I think the Model Database should be modified to have a Full Recovery Option. While writing this blog post, I remembered my another blog post where the model database log file was growing drastically even though there were no transactions SQL SERVER – Log File Growing for Model Database – model Database Log File Grew Too Big. NOTE: Please do not touch the Model Database unnecessary. It is a strict “No.” If you want to create an object that you need in all the databases, then instead of creating it in model database, I suggest that you create a new database called maintenance and create the object there.

  • Best practices for logging user actions in production

    - by anthonypliu
    I was planning on logging a lot of different stuff in my production environment, things like when a user: Logs In, Logs Off Change Profile Edit Account settings Change password ... etc Is this a good practice to do on a production enviornment? Also what is a good way to log all this. I am currently using the following code block to log to: public void LogMessageToFile(string msg) { System.IO.StreamWriter sw = System.IO.File.AppendText( GetTempPath() + @"MyLogFile.txt"); try { string logLine = System.String.Format( "{0:G}: {1}.", System.DateTime.Now, msg); sw.WriteLine(logLine); } finally { sw.Close(); } } Will this be ok for production? My application is very new so im not expecting millions of users right away or anything, looking for the best practices to keeping track of actions on a website or if its even best practice to.

  • JQuery + WCF + HTTP 404 Error

  • What to do with input during movement?

    - by user1895420
    In a concept I'm working on, the player can move from one position in a grid to the next. Once movement starts it can't be changed and takes a predetermined amount of time to finish (about a quarter of a second). Even though their movement can't be altered, the player can still press keys (perhaps in anticipation of their next move). What do I do with this input? Possibilities i've thought of: Ignore all input during movement. Log all input and loop through them one by one once movement finishes. Log the first or last input and move when possible. I'm not really sure which is the most appropriate or most natural. Hence my question: What do I do with player-input during movement?

  • permanently load module

    - by Radu
    I have a Compaq Presario CQ-61 320SQ, I am using Ubuntu 10.04 because after update to 10.10 my mouse and touchpad won't work, network won't work, sound won't work ... (I managed to fix most of them after almost a month of googling, but not all, my 2 Desktops have no problem with 10.10) so I decided to switch back to 10.04, where I have a problem: My broadband speed is very low beacause of the kernel module r8169, I downloaded the good module r8101 and every time the computer boots have a rc.local entry to fix this. Question: Can I load the modul permanently from a specific location. I heard about /etc/modules but there I need the module name, but I have to load it from a specific path (where is the default path for that) Thank you. So I studied the script: It creates the file r8101.ko in /lib/modules/uname -r/kernel/drivers/net so I think as long as nobody will delete that file, and I don't update the kernel, maybe adding r8108 to /etc/modules will work, and add r8169 to blacklist ... I will give it a try. EDIT2: So I added r8101 to /etc/modules and blacklist r8169 to /etc/modprobe.d/blacklist.conf It still uses the old module, lsmod prints: radu@adu:~$ lsmod | grep r8 r8101 67626 0 r8169 34108 0 mii 4381 1 r8169 EDIT: the module is loaded using this script that came with it: #!/bin/sh # invoke insmod with all arguments we got # and use a pathname, as insmod doesn't look in . by default TARGET_PATH=/lib/modules/`uname -r`/kernel/drivers/net echo echo "Check old driver and unload it." check=`lsmod | grep r8169` if [ "$check" != "" ]; then echo "rmmod r8169" /sbin/rmmod r8169 fi check=`lsmod | grep r8101` if [ "$check" != "" ]; then echo "rmmod r8101" /sbin/rmmod r8101 fi echo "Build the module and install" echo "-------------------------------" >> log.txt date 1>>log.txt make all 1>>log.txt || exit 1 module=`ls src/*.ko` module=${module#src/} module=${module%.ko} if [ "$module" == "" ]; then echo "No driver exists!!!" exit 1 elif [ "$module" != "r8169" ]; then if test -e $TARGET_PATH/r8169.ko ; then echo "Backup r8169.ko" if test -e $TARGET_PATH/r8169.bak ; then i=0 while test -e $TARGET_PATH/r8169.bak$i do i=$(($i+1)) done echo "rename r8169.ko to r8169.bak$i" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak$i else echo "rename r8169.ko to r8169.bak" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak fi fi fi echo "Depending module.

  • Help With Hard links And Symlinks Moving Directory And Files

    - by Julio
    This is what I would like to do. I have a symlink "/var" linking to "/tmpfs/var.1" /var - /tmpfs/var.1 I start a script called "cache_tmpfs" from /etc/rc.local on startup this script will copy /var.backup/* contents to /tmpfs/var.1/ cp -dpRxf /var.backup/* /tmpfs/var.1/ now the problem is that kernel is opening messages log file in /var/log/messages, is it possible to remove the current /var symlink and recreate a new one (that will symlink to /var.backup insteed of /tmpfs/var.1) without issues as files once opened by system become hard links?? rm /var && ln -s /var.backup /var Thanks...

  • How to impale and stack targets correctly according to the collider and its coordinate?

    - by David Dimalanta
    I'm making another simple game, a catch game, where a spawning target game object must be captured using a skewer to impale it. Here how: At the start, the falling object (in red) will fall in a vertical direction (in blue) When aimed properly, the target will fall down along the line of the skewer. (in blue) Then, another target is spawned and will fall vertically. (in red) When aimed successfully again in a streak, the second target will fall along the skewer and stacked. Same process over and over when another target is spawned. However, when I test run it on the scene tab in Unity, when impaled several targets, instead of a smooth flow and stacking it ended up overlaying it instead of stacking it up like a pancake. Here's what it look like: As I noticed when reaching the half-way of my progress, I tried to figure out how to deal with collider bodies without sticking each other so that it will actually stack like in the example of the image at no. 3. Here's the script code I added in the target game object: using UnityEngine; using System.Collections; public class ImpaleStateTest : MonoBehaviour { public GameObject target; public GameObject skewer; public bool drag = false; private float stack; private float impaleCount; void Start () { stack = 0; impaleCount = 0; } void Update () { if(drag) { target.transform.position = new Vector3 (DragTest.dir.transform.position.x, DragTest.dir.transform.position.y - 0.35f, 0); target.transform.rotation = DragTest.degrees; target.rigidbody2D.fixedAngle = true; target.rigidbody2D.isKinematic = true; target.rigidbody2D.gravityScale = 0; if(Input.GetMouseButton(0)) { Debug.Log ("Skewer: " + DragTest.dir.transform.position.x); Debug.Log ("Target: " + target.transform.position.x); } } } void OnTriggerEnter2D(Collider2D collider) { impaleCount++; Debug.Log ("Impaled " + impaleCount + " time(s)!"); drag = true; audio.Play (); } } Aside from that, I'm not sure if it's right but, the only way to stick the impaled targets while dragging the skewer left or right is to get the X coordinates from the skewer only. Is there something else to recommend it in order to improve this behavior as realistic as possible? Please help.

  • Can I get any logging and error output from Flash?

    - by Dave M G
    To further provide better information for my other question about browsers and Pulse audio, I wanted to see if I could get some kind of helpful log information. I've looked at logs from both Pulseaudio and Firefox, but don't see anything like an error in either of them. The problem I'm experiencing may be coming from Flash. Is there a way I can trap specifically any log output from Flash? Update: I've downloaded the Linux Flash Player 10.3 Plugin content debugger, and I've installed libflashplayer.so in ~/.mozilla/firefox/plugins/, and copied the user/* files to /user. I've also set up mm.cfg to say: ErrorReportingEnable=1 TraceOutputFileEnable=1 MaxWarnings=50 TraceOutputFileName=/home/dave/.macromedia/Flash_Player/Logs/flashlog.txt And I rebooted just to be sure everything was starting fresh. However, after playing a Flash video from Youtube, flashlog.txt is not being generated. How can I be sure that logging is in fact enabled, so I can tell whether I'm simply not getting errors or I haven't set up logging correctly?

  • Script to setup ubuntu as a wireless accesspoint on a bridge mode

    - by nixnotwin
    I use the following script to make my netbook a full-fledged wireless accesspoint. It creates a bridge with eth0 and wlan0 and starts hostapd. #!/bin/bash service network-manager stop ifconfig eth0 0.0.0.0 #remove IP from eth0 ifconfig eth0 up #ensure the interface is up ifconfig wlan0 0.0.0.0 #remove IP from eth1 ifconfig wlan0 up #ensure the interface is up brctl addbr br0 #create br0 node hostapd -d /etc/hostapd/hostapd.conf > /var/log/hostapd.log & sleep 5 brctl addif br0 eth0 #add eth0 to bridge br0 brctl addif br0 wlan0 #add wlan0 to bridge br0 ifconfig br0 192.168.1.15 netmask 255.255.255.0 #ip for bridge ifconfig br0 up #bring up interface route add default gw 192.168.1.1 # gateway This script works efficiently. But if I want to revert back to use Network Manager, I cannot do it. The bridge simply cannot be deleted. How can I modify this script so that if I run bridge_script --stop, the bridge gets deleted, network manager starts and interfaces behave as if the machine had a fresh reboot.

  • Apache won't accept external requests

    - by Eric
    I am running Apache 2.2 on windows and I would like to access it remotely. Currently I can only access it from my local machine. I know the problem is not port forwarding because I tested it with other web servers (written in python). My httpd.conf file is below. I installed apache with the PHP installer. # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path.

  • If I define a property to prototype appears in the constructor of object, why?

    - by Eduard Florinescu
    I took the example from this question modified a bit: What is the point of the prototype method? function employee(name,jobtitle,born) { this.name=name; this.jobtitle=jobtitle; this.born=born; this.status="single" } employee.prototype.salary=10000000; var fred=new employee("Fred Flintstone","Caveman",1970); console.log(fred.salary); fred.salary=20000; console.log(fred.salary) And the output in console is this: What is the difference salary is in constructor but I still can access it with fred.salary, how can I see if is in constructor from code, status is still employee property how can I tell for example if name is the one of employee or has been touch by initialization? Why is salary in constructor, when name,jobtitle,born where "touched" by employee("Fred Flintstone","Caveman",1970); «constructor»?

  • apportcheckresume recurring error and gnome shell fixations

    - by feedyourhead
    Since installing Ubuntu 12.10 Gnome remix I encounter systemm's unpredictable and unwanted behavior. Almost after each resume from suspend (or even after unlocking the screen after it goes blank) I get apportcheckresume error and message "Ubuntu 12.10 has encountered an internal error".Many times the system event wont resume and I need to restart it. Other times log in screen is not visible, the screen is blank and i have to write my password "in blanco". Sometimes additional thing also happens - textures get messed up and background and windows get distorted by horizontal lines Sorry I can't localize the log file for the errors. My system specification: Ubuntu 12.10 3.5.0-19-generic Gnome 3.6 Thinkpad T400 Graphics Mobile Intel® GM45 Express Chipset Intel® Core™2 Duo CPU P8600
