• GIT not functionnal on Mac OS X Lion?

  - by user1187727

  I am trying to use GIT to manage my computing projects. But all commands using GIT do not respond on my terminal. For example if I try git --version followed by entry keyboard typing, a blank line appear and wait until ever. If I type again the entry key on my keyboard the command line is again available but nothing appear. It's the same for all git function that I type. Do you have any solution or explanation for this ?

• Rails 3 / RVM - Acts_as_list compiled locally - Why Can't Ruby See This Gem?

  - by rabbit on rails

  I cannot figure out why rails/ruby cannot see this gem, despite each telling me that the gem is visible. I compiled this gem locally from a github branch since the main version seems to be broken in Rails 3. Or perhaps I am missing something else entirely.

I'd really appreciate it! ** UPDATE -- Response to Andrew Marshall's suggestion** I changed Gemfile to read the gem directly from git, but it did not resolve the problem. Does this mean that there is a problem with this gem? The error message is not very helpful ;-) Removed: Ovid:lightserve dlipa$ bundle show acts_as_list Could not find gem 'acts_as_list' in the current bundle.

I just looked in the gem and it appears there is no file called 'acts_as_list' in the gem. So it appears to be idiosyncratic, albeit poorly reported by Rails/Ruby. The API appears to have changed to: ruby-1.9.2-p180 :003 > require 'active_record/acts/list' => nil ruby-1.9.2-p180 :004 > ActiveRecord::Acts::List => ActiveRecord::Acts::List

• Arduino - AdHoc Network Setup

  - by methodMan

  I`m currently working with an arduino trying to build an adhoc network to which a device can connect to and send web request to. The problem I am currently having is that I can only set up one connection and then when that connection is terminated (client.stop()) all subsequent connections are not picked up by the server, even a curl command just sits there spinning. The first connection I start when I reset the server works fine and I am able to talk to the server; but after that, the arduino can no longer find new clients (even though it's trying with the library given). I`m using the sparkfun library for the wifly shield cloned from github, along with an Arduino Uno. My current code is based off their default example 'WiFly_AdHoc_Example' but I had to remove a few things to get the network to start up which might be the cause of this problem. Here is the .ino file that I am running. #include <SPI.h> #include <WiFly.h> //#include <SoftwareSerial.h> //SoftwareSerial mySerial( 5, 4); //Part from example not used(see below) WiFlyServer server(80); void setup() { Serial.begin(9600); //The code below is from the example but when I run it the WiFly will hang // on Wifly.begin(). Without it the WiFly starts up fine but only works for // one request. //mySerial.begin(9600); //WiFly.setUart(&mySerial); // Tell the WiFly library that we are not //using the SPIUart Serial.println("**************Starting WiFly**************"); // Enable Adhoc mod WiFly.begin(true); Serial.println("WiFly started, creating network."); if (!WiFly.createAdHocNetwork("wifly")) { Serial.print("Failed to create ad hoc network."); while (1) { // Hang on failure. } } Serial.println("Network created"); Serial.print("IP: "); Serial.println(WiFly.ip()); Serial.println("Starting Server..."); server.begin(); Serial.print("Server started, waiting for client."); } void loop() { delay(200); WiFlyClient client = server.available(); if (client) { Serial.println("Client Found."); // a string to store received commands String current_command = ""; while (client.connected()) { if (client.available()) { //Gets a character from the sent request. char c = client.read(); if (c=='#' || c=='\n') //End of extraneous output { current_command = ""; } else if(c!= '\n') { current_command+=c; } if (current_command== "get") { // output the value of each analog input pin for (int i = 0; i < 6; i++) { client.print("analog input "); client.print(i); client.print(" is "); client.print(analogRead(i)); client.println("<br />"); } } else if(current_command== "hello") { client.println("Hello there, I'm still here."); } else if (current_command== "quit") { client.println("Goodbye..."); client.stop(); current_command == ""; break; } else if (current_command == "*OPEN*") { current_command == ""; } } } // give the web browser time to receive the data delay(200); // close the connection client.stop(); } } If anyone understands this better then I (I`m new to arduino) please leave some helpful comments. Or just help me out on getting this little web server up and running so that I can hit it with more then one request. If there is any other helpful information I can provide please let me know. Thanks for reading and hope you can help. EDIT: Using telnet I can successfully connect (the first time) and send commands to the arduino including one to terminate the connection (calls the client.stop() method). But when I try to reconnect though telnet, it says the connection was successful but on the arduino it's still looping thinking the client is still false. WHAT??? I know right, I'm getting mixed messages from telnet vs arduino. None of the commands work obviously since the ardunio is still looping waiting for a client that evaluates to true. I'm gonna take a look at WiFlyServer from the library I imported and see if I can dig up the problem because somehow that server.available() method isn't finding new clients. Noticing a lot of TODO's in the library code.... EDIT: So I found the reason for the problem, it was in WiFlyServer.cpp file from the sparkfun library. The code that was causing the reconnect issue was infact in the server.availible() method. Right at the top of the method, there is a check: // TODO: Ensure no active non-server client connection. if (!WiFly.serverConnectionActive) { activeClient._port = 0; } For some reason when I comment this out, I can reconnect fine and everything works as it should. I will now dive into the library and see if I can fix this, I'm not exactly sure what this is doing but it gets called when the server connection is not active and is somehow blocking subsequent connections. Does anyone have any ideas how I might get to the root of this problem without using this commenting hack? Please help, no-one has commented or answered yet! Don't you want to join in on the fun???

• No internet via wifi/ethernet after 14.04 upgrade

  - by Rhys Evans

  I have just updated to Ubuntu 14.04 LTS on my laptop, and I seem to be having some internet problems. I have no internet connection through wifi or Ethernet, after both working in the previous version. I am not at all knowledgeable of Ubuntu and its workings, so if you could just tell me what to do, what to show you by just telling me commands etc. I think would be the only way I will understand sorry! I am asking this after many searches, all being in vein after needing a step involving some sort of internet access, which I can't get! So sorry if it has been answered somewhere, if so, please send me there! Cheers This is what I get when using sudo lspci -v: lspci -v

• Advice for creating fog of war on tilemap game XNA

  - by Sigh-AniDe

  I have created a 2D Tile Based game. The game has a single path that the sprite can move on. I want to create to make the entire screen black except for where the sprite is. The sprite has commands such as left where he keeps looking left, right where he keeps looking right and move forward where he moves in the direction he is looking. I want to make it such that when he looks left then the tile on the left of the sprites fog should be removed and so on for all the sides. What is the best way to do this? Is there any tutorials that you guys know of that i can take a look at? Thanks

• /sbin/getty process causing 100% CPU utilization

  - by scrrr

  I have an instance of Ubuntu 12.04 LTS (GNU/Linux 3.2.0-25-virtual i686) running as a KVM-VM on a host-machine that runs one more VM beside it. I deploy a Ruby on Rails application using the Capistrano deployment-gem. However, if I deploy twice in a row in a short time, the CPU usage jumps to 100% because of the /sbin/getty process. How can this be? I believe getty is a rather simple program that passes a login-name from a terminal to a login-process. Also: In my Capfile (Capistrano configuration file) I am running certain commands after the Rails application is deployed including a call to sudo /sbin/restart <APPNAME> which is an upstart task. Could this be related somehow? I can always kill the getty process and the problem is gone until the next deployment, but I would rather understand and fix the problem. Any help is appreciated. Attached is a screenshot of my problem.

• How to use integrated Intel graphics instead of Nvidia graphics on MacBook Pro?

  - by Benjamin Geese

  I am running Ubuntu 12.04 64bit on MacBook Pro 15" 2010 (MacBookPro6,2) and I would like to use the integrated Intel graphics instead of the dedicated Nvidia graphics Ubuntu boots with on this machine. I am booting with UEFI, not REFIT or similar. I managed to switch to UEFI with the help of this page. This wiki page also contains tips on switching to Intel graphics which include some (for me) cryptic boot commands to grub. However if I follow the guide, my display stays just black. Currently, I am only looking for solution to use Intel graphics for Ubuntu to save power and keep my MacBook cool. Dynamic switching or stuff like that is not required.

• How can I resize pixel art in Pyglet without making it blurry?

  - by Renold

  I have a tileset of 8x8 pixel images, and I want to resize them in my game so they'd be double that (16x16 pixels, e.g. turning each pixel into a 2x2 block.) What I'm trying to achieve is a Minecraft-like effect, where you have small pixel images scale to larger blockier pixels. In Pyglet, the sprite's scale property blurs the pixels. Is there some other way? Update: So I changed my code, but I'm still having the same issue (nothing changed.) Of course, the GL commands are kind of mysterious to me: gl.glEnable(gl.GL_TEXTURE_2D) image = resource.image('tileset.png') texture = image.get_texture() gl.glBindTexture(gl.GL_TEXTURE_2D, texture.id) gl.glTexParameteri(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MIN_FILTER, gl.GL_NEAREST) texture.width = 16 # resize from 8x8 to 16x16 texture.height = 16 image.blit(100, 30) # draw Is there something else I should try?

• Backup options in SharePoint 2007

  - by sreejukg

  It is very important to make sure the server farm backup is taking properly, making sure that in case of any disaster, the administrator has the latest backup that can be used to restore. This articles addresses some of the options available for backup/restore in SharePoint 2007 Backup There are two options that can be utilized to take backup of SharePoint sites. Using SharePoint Central Administration website Using SharePoint central administration website, you can do backup/restore from user interface. Using central administration website you can back up the following · Server farm · Web application · Content databases Follow these steps to take backup of the server farm using central administration 1. Open Central administration website 2. Navigate to Operations -> Backup and Restore -> Perform a backup 3. Here you will have options to choose the item to back up. Select Farm (the top most item in the list) 4. Once you select the items to backup, click on “Continue to backup options” 5. Select “Full” as type of backup. 6. In the backup file location, enter the path where you need to store the backup. The path should be according to the UNC, for e.g. for c drive you may use \\server\c$\mybackupFolder 7. Click ok 8. Now you will be redirected to Backup and Restore Status page. This page shows the progress for the backup operation. You can use the refresh button to update the status of backup(this page will automatically refresh in every 30 seconds). Once completed you can find the files in the specified folder. Using STSADM website SharePoint comes with a STSADM command line tool. STSADM provides lot of administrative operations that can be performed on SharePoint 2007 sites. You can find STSADM command from the following location C:\Program Files\Common Files\Microsoft shared\web server extensions\12\bin (You may change the drive letter according to your installation) STSADM provides a method for performing the Office SharePoint Server 2007 administration tasks at the command line or by using batch files or scripts. STSADM provides access to operations not available by using the Central Administration site The general syntax for STSADM is as follows STSADM -operation Operation Name –parameter1 value1 –parameter2 value2 ……….. Using STSADM you can back up the following · Server farm · Web application · Content databases To perform any STSADM, operation you need to be a member of administrators group. Follow these steps to take backup of SharePoint server farm using STSADM tool. Note: make sure you are logged in to the computer where central administration website is installed. 1. Open the Command prompt (You should run command prompt with administrator privileges) 2. Change the working directory to C:\Program Files\Common Files\Microsoft shared\web server extensions\12\bin 3. Enter the command, then press enter Stsadm –o backup -directory <UNC path> -backupmethod full 4. You will get success / failure message once the command finishes. How to schedule the backup There is no option to schedule a backup using central administration site. Also there is no operation provided by STSADM to automate the backup. The farm administrators need to take backup in regular intervals. To achieve this, you can write a batch file that includes STSADM command to take full backup of the server. This batch file can be scheduled using windows task scheduler to execute in certain intervals. Sample of the batch file 1. Open notepad(or any other text editor) 2. Enter the following commands @echo off echo =============================================================== echo Back up the farm to <C:\backup> echo =============================================================== cd %COMMONPROGRAMFILES%\Microsoft Shared\web server extensions\12\BIN @echo off stsadm.exe -o backup -directory "<\backup>" -backupmethod full echo completed 3. Save the file with .bat extension You can schedule this batch file as you require. Other Options Using STSADM tool, you will be able to take backup for individual site collection. The syntax for this is stsadm -o backup -url <URL name for site collection> -filename <file name> [-overwrite] The explanations for the parameters are as follows. -url The url of the site collection you need to backup -filename The name of the backup file. E.g. c:\backup.bak -overwrite optional. Indicates if the filename specified exists, whether to overwrite or not. If you are creating the batch file for scheduling the backup for a site collection, you may need to specify the backup filename automatically created. It is an option that you can generate the filename with date so that you can keep backup for each day. e.g. The following commands can be utilized create a site collection backup. @echo off echo =============================================================== echo Back up the farm to <C:\backup> echo =============================================================== echo =============================================================== echo getting todays date to a variable echo =============================================================== @For /F "tokens=1,2,3 delims=/ " %%A in (‘Date /t’) do @( Set Day=%%A Set Month=%%B Set Year=%%C Set todayDate=%%C%%B%%A ) cd %COMMONPROGRAMFILES%\Microsoft Shared\web server extensions\12\BIN @echo off stsadm -o backup -url <sitecollection url> -filename \\ServerName\ShareName\Backup_%todayDate%.bak -overwrite echo completed To read more about backup STSADM operation, read this http://technet.microsoft.com/en-us/library/cc263441.aspx

• Script to establish SSH tunnel and then run another program that uses the tunnel

  - by Rob Hills

  I am running a GUI app (Gnucash) that connects to a remote Postgres database via a secure shell session. I can use the SSH -L command to tunnel a local port and then separately run Gnucash and this works fine. What I'd like to do is use a single shell script that sets up the tunnel and then calls Gnucash. Is that possible? If so, how do I do it? Currently, I run commands like the following in 2 separate terminal windows: ssh -L 5433:127.0.0.1:19097 [email protected] gnucash postgres://gnucash@localhost:5433/gnucash_db If I simply put both lines in a shell script, the first line drops me into the remote shell and the second line doesn't execute until I exit the remote shell. TIA, Rob Hills

• xgamma -display parameter for dual monitor setup

  - by Shiplu

  I want to change gamma for my first monitor. Every time I invoke xgamma with different -display parameters it somehow points to my second monitor. But I want to modify first one. I tried these commands. The parameters I have used for -display are :0, :0.0, :0.1, :1.0, :1.1, :1. Only the first 2 works. But it points to my second monitor. Not the first one. Here is a shell script to test it. shiplu@KubuntuD:~$ xgamma -display :0 -> Red 1.000, Green 1.000, Blue 1.000 shiplu@KubuntuD:~$ xgamma -display :0.0 -> Red 1.000, Green 1.000, Blue 1.000 shiplu@KubuntuD:~$ xgamma -display :0.1 xgamma: unable to open display ':0.1' shiplu@KubuntuD:~$ xgamma -display :1.0 xgamma: unable to open display ':1.0' shiplu@KubuntuD:~$ xgamma -display :1.1 xgamma: unable to open display ':1.1' shiplu@KubuntuD:~$ xgamma -display :1 xgamma: unable to open display ':1' How can I change the gamma for the first/primary monitor?

• Record and Play your WebLogic Console Tasks Like a DVR

  - by james.bayer

  Automation using WebLogic Scripting Tool Today on the Oracle internal mailing list for WebLogic Server questions someone asked how to automate the configuration of the thread model for WebLogic Server and they were having trouble with the jython scripting syntax.  I’ve previously written about this feature called Work Managers and the associated constraints.  However, I did not show how to automate the process of configuring this without the console using WebLogic Scripting Tool – the jython scripting automation environment abbreviated as WLST.  I’ve written some very basic introductions to WLST before and there is also an Oracle By Example on the subject, but this is a bit more advanced.  Fear not because there is a really easy-to-use feature of the WLS console that lets you “Record” user actions just like a DVR.  Using these recordings of the web-based console, you can easily create a script even if you are unfamiliar with the WLST syntax and API.  I’m a big fan of both DVR’s and automation as can be evidenced with this old Halloween picture taken during simpler times.  Obviously the Cast Away and The Big Labowski references show some age.  I was a big Tivo fan-boy back in the day and I still think it’s the best DVR. I strongly believe that WebLogic Scripting Tool (WLST) is an absolutely essential tool for automating administration tasks in anything beyond a development environment.  Even in development environments you can make a case that it makes sense to start the automation for environments downstream.  I promise you that once you start using it for any tasks that you do even semi-regularly, you won’t go back to clicking through the console.  It’s simply so much more efficient and less error-prone to run a script. Let’s say you need to create a Work Manager and MaxThreadsConstraint – the easy way to do it is configure it in the WLS console first while capturing the commands with a recording.  See the images for the simple steps – click to enlarge. Record Console Configurations to a File Review the Recordings and Make Slight Modifications In order to make the recorded .py file directly callable as a stand-alone script I added calls to the connect() and edit() functions at the beginning and calls to disconnect() and exit() at the end – otherwise the main section of the script was provided by the console recording.  Below is the resulting file I saved as d:/temp/wm.py connect('weblogic','welcome1', 't3://localhost:7001') edit() startEdit()   cd('/SelfTuning/wl_server') cmo.createMaxThreadsConstraint('MaxThreadsConstraint-0')   cd('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName)) cmo.setCount(5) cmo.unSet('ConnectionPoolName')   cd('/SelfTuning/wl_server') cmo.createWorkManager('WorkManager-0') cd('/SelfTuning/wl_server/WorkManagers/WorkManager-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName))   cmo.setMaxThreadsConstraint(getMBean('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0')) cmo.setIgnoreStuckThreads(false)   activate() disconnect() exit() Run the Script If you want to test it be sure to delete the Work Manager and MaxThreadConstraint that you had previously created in the console.  Do something like the following - set up the environment and tell WLST to execute the script which happens in the first 2 lines, the rest doesn’t require any user input: D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server\bin>setDomainEnv.cmd D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server>java weblogic.WLST d:\temp\wm.py   Initializing WebLogic Scripting Tool (WLST) ...   Welcome to WebLogic Server Administration Scripting Shell   Type help() for help on available commands   Connecting to t3://localhost:7001 with userid weblogic ... Successfully connected to Admin Server 'examplesServer' that belongs to domain 'wl_server'.   Warning: An insecure protocol was used to connect to the server. To ensure on-the-wire security, the SSL port or Admin port should be used instead.   Location changed to edit tree. This is a writable tree with DomainMBean as the root. To make changes you will need to start an edit session via startEdit().   For more help, use help(edit)   Starting an edit session ... Started edit session, please be sure to save and activate your changes once you are done. Activating all your changes, this may take a while ... The edit lock associated with this edit session is released once the activation is completed. Activation completed Disconnected from weblogic server: examplesServer     Exiting WebLogic Scripting Tool.   Now if you go back and look in the console the changes have been made and we now have a compete script.  Of course there is a full MBean reference and you can learn the nuances of jython and WLST, but why not the WLS console do most of the work for you!  Happy scripting.
