Resizing Partition on UBUNTU

SOURCE: 

https://askubuntu.com/questions/116351/increase-partition-size-on-which-ubuntu-is-installed/116367 

As a matter of fact, you CAN enlarge the root filesystem while Ubuntu is running (I learned this recently myself here) - this sounds incredible but it's true :)
Here's the list of steps for a simple scenario where you have two partitions, /dev/sda1 is an ext4 partition the OS is booted from and /dev/sdb2 is swap. For this exercise we want to remove the swap partition an extend /dev/sda1 to the whole disk.
As always, make sure you have a backup of your data - since we're going to modify the partition table there's a chance to lose all your data if you make a typo, for example.
Run sudo fdisk /dev/sda

• use p to list the partitions. Make note of the start cylinder of /dev/sda1

• use d to delete first the swap partition (2) and then the /dev/sda1 partition. This is very scary but is actually harmless as the data is not written to the disk until you write the changes to the disk.

• use n to create a new primary partition. Make sure its start cylinder is exactly the same as the old /dev/sda1 used to have. For the end cylinder agree with the default choice, which is to make the partition to span the whole disk.

• use a to toggle the bootable flag on the new /dev/sda1

• review your changes, make a deep breath and use w to write the new partition table to disk. You'll get a message telling that the kernel couldn't re-read the partition table because the device is busy, but that's ok.

Reboot with sudo reboot. When the system boots, you'll have a smaller filesystem living inside a larger partition.
The next magic command is resize2fs. Run sudo resize2fs /dev/sda1 - this form will default to making the filesystem to take all available space on the partition.
That's it, we've just resized a partition on which Ubuntu is installed, without booting from an external drive.

Moving from Jenkins (Tomcat) to Jenkins Standalone [UBUNTU]

SSH into ubuntu
sudo apt-get update
sudo apt-get install jenkins
sudo service jenkins stop
cd /var/lib/jenkins
rm -rf ./*
cp -a /var/lib/tomcat8/webapps/jenkins .
chown -R jenkins .
chgrp -R jenkins .
sudo service jenkins start

Jenkins Webhook, Only build Specific Branch after receiving web hook. e.g. only build master

With a web hook a request is made regardless of which branch it is on. Initially this would cause my Jenkins to initiate a build (on master) even when the commit was pushed to develop. To fix this we can follow these steps:

• Open your jenkins project
• configure it to use: Poll SCM (but leave the schedule blank)
• save and exit

in Bitbucket / Github create a web hook and enter the following url (replacing your jenkins & git project details)

http://<your domain>/jenkins/git/notifyCommit?url=<your git repository url>

eg

http://fakewebsite.com:8080/jenkins/git/notifyCommit?url=git@bitbucket.org:faceuser/fakeproject.git

This will do the following:

1. Send a web hook request to your jenkins
2. Jenkins will process this request and look for Jenkins projects using the specified gitproject (e.g. git@bitbucket.org:faceuser/fakeproject.git)
3. Jenkins will then poll git looking for changes on the specified branch

Jenkins unable to post to twitter due to Twitter-plugin not using SSL

Same problem as this
https://issues.jenkins-ci.org/browse/JENKINS-25740

 but the solution was to also replace jar the following files under
$jenkinsdir/plugins/twitter/WEB-INF/lib

twitter4j-core-3.0.3.jar with twitter4j-core-3.0.5.jar
twitter4j-async-3.0.3.jar with twitter4j-async-3.0.5.jar

Download from
http://central.maven.org/maven2/org/twitter4j/twitter4j-core/3.0.5/

reload jenkins deployment in tomcat manager and voila! it works!

Jenkins job cannot create dirs under /home/jenkins/.m2/

ssh to the machine and check who ones the files/dirs if it owned by root change it to the tomcat users

sudo chown -R username:group directory




Python Extracting 9 digit number from tomcat access log files into a unique set and printing to the screen

I had to extract all the 9 digit IDs that were used in a tomcat access log. Here is how I solved it with Python

import re
import os

from collections import Counter
# Compile the regular expressions \d{9} selects numbers that are 9 digits longs
p = re.compile('\d{9}', re.IGNORECASE)
output_file_name = 'output.csv'
# Initiate an array to store the students ids in
most_active = []
#for the files in this directory
for name in os.listdir("."):
    #if it starts with localhost_access_log & ends with a .txt extension
    if name.startswith("localhost_access_log") and name.endswith(".txt"):
        #read its contents
        with open(name, 'r') as myfile:
            print("Reading file: "+name)
            data=myfile.read().replace('\n', '')
            #Add the regex matches to the array
            most_active = most_active + re.findall(p, data)
# Count how many times a student id is repeated in the list
# This will tell us the most active students in the app
count = Counter(most_active)

# For each of the students, order them from most common to least
output_file = open(output_file_name,"w")
output_file.write("Student ID, Activity\n")
for student in count.most_common():
    line = str(student[0])+","+str(student[1])
    #print(line)
    
    output_file.write(line+"\n")
output_file.close()
print("File written successfully: "+output_file_name)
#Print out the total amount of students
print("Total Students:"+ str(len(count)))

Missing iOS Distribution signing identity

After building and Archiving my App I was unable to Validate or Upload into the App Store due to missing iOS Distribution identity. 

After verifying that all credentials exist in the member center, restarting XCode and iOS the following post from stackoverflow fixed my issue

http://stackoverflow.com/a/35406327/5335798

1. Download https://developer.apple.com/certificationauthority/AppleWWDRCA.cer
2. Double-click to install to Keychain.
3. Then in Keychain, Select View -> "Show Expired Certificates" in Keychain app.
4. It will list all the expired certifcates.
5. Delete "Apple Worldwide Developer Relations Certificate Authority certificates" from "login" tab
6. And also delete it from "System" tab.

FIXED Invalid Apple Watch icon file names must match pattern “*@x.png”

Invalid Icon Name - The watch application 'Ellucian GO.app/Watch/Ellucian GO WatchKit App.app' contains an invalid icon file name 'Ellucian GO.app/Watch/Ellucian GO WatchKit App.app/AppIcon44x44@2x.png'. Make sure that icon file names follow the pattern "*<dimension>@<scale>x.png" and they match the required dimensions. Please visit https://developer.apple.com/watchkit/ for more information

I discoved the fix to this to be the following:
Disabled WatchOS 1.0

Making sure the the Icons are called APP ICON:
AppIcon24x24@2x.png
AppIcon27.5x27.5@2x.png
AppIcon29x29@2x.png
AppIcon29x29@3x.png
AppIcon40x40@2x.png
AppIcon44x44@2x.png
AppIcon86x86@2x.png
AppIcon98x98@2x.png

Clearing derived data & Restart XCODE
Deleted all files within XCODEs derived data folder

Build and Resubmit
Voila! No issues with Icons anymore!!!

[Ellucian Mobile] Uknown error for registration-register

Database Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production PL/SQL Release 11.2.0.4.0 - Production

grails Grails 2.4.3.

Problem Whenever one of our Devs compiles and installs a modification or a new PLSQL report the Grails application stops working and only reponds with

"Uknown error for registration-register"

Solution for us was: make sure studentAPI Installed on the Database Server matches the StudentAPI war file on the Ellucian Mobile server

mongodb authentication failed code 18

If you are receiving this error and are 100% sure you are using the correct DATABASE username/password. try to update your mongodb client

PHP
pecl upgrade mongodb

Grails
add to to the BuildConfig.groovy file

compile "org.grails.plugins:mongodb:5.0.0.RC1"

Also if you are having problems serializing a list in Grails and only receiving the first item. It may be because <Domain Class>.list() does not return a list or array item but a MongoDB collection now (since MongoDB updates) to remedy this for now I have cast the lists to Arrays.

Sudo ./opmnctl startall

If you do not "super user do" stop and then start opmnctl you will receive the following error
