Holy Thor! My blog just got scraped by someone in Israel!

So... Yeah...

I have a blog.
Mostly articles about movies, tech and science.
I get roughly 2,000 to 3,000 views per month.

And recently I posted an article about the recent change of PM in Australia.
It included the word "Palestine".
And on one day... Actually in one hour... I got 1,932 page views.

Wait. What?
I'm not important.
I just comment on some issues I feel relevant to the events of the day.

So just what did my stats show?

Oh lord.
So... I'm not actually saying Mossad have scraped my site.
But seriously...
I have 1,932 pages that feel relevant to someone in Israel?

Wow. Thanks guys.
I had no idea I had written many posts.
Hope you like them.

So... Yeah... Australia has a new prime minister... Oh. And goats. And a giraffe.

It was a Monday that's why.

What is it with new these people?

And what is it with the "Prime" part?

Now Optimus Prime had it right.
He led the Transformers for years.
So maybe Mal should change his name to "Malcolm Prime".
Maybe he'd last longer.

And just why do they want to be prime minister?

After all, the first thing our new one did is re-affirm the old ones stance on climate change and marital equality.
Why take the leadership and then say the same as the previous nut job?
Is it the money? The groupies?

And apparently they all still think that marriage equality is "Redefining Traditional Marriage."

It's already been redefined dozens of times you dumb ass.

Imagine 4AD Palestine.
So... Here's my father and Ben comes up, points at me and says "Hey. I'll have that one."

"Oh. Ok." says my father and picks up his holy book.

Starts thumbing through it and says "Oh. Sorry. Forgot. I'm an illiterate goat herder. Let's go and see a holy man."

So we all walk off to the temple because the government hasn't invented public transport yet.
Or clean water.

And the holy man thumbs through the holy book and picks one of the many "Traditional" marriages in his book and says:

"Ah yes. Here's one that fits. That'll be three goats and a cow."

And I'm "What the fuck?" although I can't use that last word because it wasn't invented until medieval times.

So Ben says "Wait. Can't I just have her as a slave and marry her later? Kinda like layby?"

And the holy man grits his teeth and says "Well... That is in the book. But the goats and cow thing is the traditional thing at the moment. So there you go."

And I'm stunned and "Seriously? Hey I'm worth more than that. The surgery alone is going to cost more than that."

So I turn to Ben and say:

"Three goats and a cow? No way dude. You want me you gotta get three goats and a giraffe. Haul your ass down to Kenya and bring back one of those fuckers."

He stares at me.

"And don't be thinking you can just lead it into Jerusalem. You gotta ride that bad boy."

"Traditional Marriage" my ass.

I want an AWESOME marriage.

Deleting/Reinstalling RubyMine on Mac OS-X

I've been upgrading my RubyMine installation for ages now as new versions and updates have occurred.

Recently I had the beginnings of Settings-Hell where settings vanished or inspections switched on or off randomly.

Furthermore I had a bunch of weird "Open-A-File-And-RM-Switches-To-A-Different-Project" issues.

So I decided it was time to whack it from my machine and re-install it.

For posterity here are the steps:

Next create a backup folder to save your existing install if anything goes wrong:

mkdir ~/RubyMineBackup
mkdir ~/RubyMineBackup/Preferences
mkdir ~/RubyMineBackup/Caches
mkdir ~/RubyMineBackup/Application\ Support
mkdir ~/RubyMineBackup/Logs
mkdir ~/RubyMineBackup/Applications

Next RubyMine and under Help->Register copy your user name and license key somewhere safe (such as the backup folder).

Now move all the preferences, caches, logs and the application itself to that backup folder:

mv ~/Library/Preferences/Rubymine70          ~/RubyMineBackup/Preferences
mv ~/Library/Preferences/Rubymine71          ~/RubyMineBackup/Preferences
mv ~/Library/Caches/RubyMine70               ~/RubyMineBackup/Caches
mv ~/Library/Caches/RubyMine71               ~/RubyMineBackup/Caches
mv ~/Library/Application\ Support/RubyMine70 ~/RubyMineBackup/Application\ Support
mv ~/Library/Application\ Support/RubyMine71 ~/RubyMineBackup/Application\ Support
mv ~/Library/Logs/RubyMine70                 ~/RubyMineBackup/Logs
mv ~/Library/Logs/RubyMine71                 ~/RubyMineBackup/Logs
mv /Applications/                ~/RubyMineBackup/Applications

(Obviously you may not need both the 70 and 71 folders. Check your machine for the folders)

Now go to JetBrains and re-download the latest version.
Start it up and enter your registration details.

FYI While starting I tend to switch to the "Darcula" theme.

Now shut RM down and do this to start RM under JDK 1.7 or newer:

vi /Applications/

Roughly line 87, you'll see this:


Change the "" value to this:


I like more memory as I often have up to 7 or 8 projects open simultaneously.

So copy the rubymine.vmoptions file:

cp /Applications/ ~/Library/Preferences/rubymine70

Now edit the ~/Library/Preferences/rubymine70rubymine.vmoptions file from this:


To this:


Now re-start RubyMine.

Once it's up install your plugins.
I use these ones:

Docker integration
Markdown support
Bootstrap 3
Git Flow Integration
GitLab integration

YMMV but mine seems to be much more stable now.

"rvm install jruby-" insists on installing pre1, rc1 or rc2

So... Yeah...

Been eagerly awaiting jruby-9000. And used rvm to install the pre1, rc1 and rc2 versions for testing against micro-services.

Then crashed right into a problem when the final release came out.

I tried to "rvm install jruby-" and it said there was already a cached version "ruby-".

Ok I thought, so I did "rvm list" and uninstalled all the previous jrubies.

Then removed any reference to jruby from "~/.rvm/archives".

Then "rvm get stable".

Then "rvm install jruby-" again.

To my chagrin, it did this:

Searching for binary rubies, this might take some time.
Found remote file
...compilation elided...

Guessing that there may actually be a release version on s3, I wget'd ""

Luckily that worked and I copied the file to "~/.rvm/archives".

I uninstalled and removed the other "pre1" version and tried again.

But no.
Despite having jruby-bin- in the archives folder, rvm insists on downloading the pre1 version.

Then the "Ahaha!"

After mucking about with rvm --debug and --trace commands I found this wonderful thing in the output (which was frickin ginormous):

+ 1437712726.N /scripts/functions/selector_parse : __rvm_ruby_string_latest()  12 > [[ -z jruby-9\.0\.0\.0.* ]]

#Ed: This looks interesting...
++ 1437712726.N /scripts/functions/selector_parse : __rvm_ruby_string_latest()  -221 > command cat /Users/kimberleyscott/.rvm/config/known_strings

++ 1437712726.N /scripts/functions/selector_parse : __rvm_ruby_string_latest()  -219 > __rvm_version_sort
++ 1437712726.N /scripts/functions/selector_parse : __rvm_ruby_string_latest()  -218 > __rvm_tail -n 1

#Ed: Notice the regex
++ 1437712726.N /scripts/functions/selector_parse : __rvm_ruby_string_latest()  -220 > __rvm_grep 'jruby-9\.0\.0\.0.*'

++ 1437712726.N /scripts/functions/selector_parse : __rvm_ruby_string_latest()  -463 > cat /Users/kimberleyscott/.rvm/config/known_strings
++ 1437712726.N /scripts/functions/support : __rvm_tail()  0 > tail -n 1
++ 1437712726.N /scripts/functions/utility : __rvm_version_sort()  1 > LC_ALL=C
++ 1437712726.N /scripts/functions/support : __rvm_grep()  0 > GREP_OPTIONS=
++ 1437712726.N /scripts/functions/utility : __rvm_version_sort()  1 > command sort -t. -k 1,1n -k 2,2n -k 3,3n -k 4,4n -k 5,5n
++ 1437712726.N /scripts/functions/support : __rvm_grep()  0 > command grep 'jruby-9\.0\.0\.0.*'
++ 1437712726.N /scripts/functions/utility : __rvm_version_sort()  -167 > sort -t. -k 1,1n -k 2,2n -k 3,3n -k 4,4n -k 5,5n
++ 1437712726.N /scripts/functions/support : __rvm_grep()  -260 > grep 'jruby-9\.0\.0\.0.*'

# Ed: and here is the result:
+ 1437712726.N /scripts/functions/selector_parse : __rvm_ruby_string_latest()  20 > new_ruby_string=jruby-

Well... "~/.rvm/config/known_strings" looks like an interesting file doesn't it?

And lo and behold, I can now see how the rvm script decided on pre1.
so I changed this:

# this strings are matched only when partial version was provided

to this:

# this strings are matched only when partial version was provided
#jruby- - commented for safety

And did a fresh "rvm --debug install jruby-".
Loads of green and purple output.
But wayhey! Installed.

rum now shows it installed:

rvm rubies

 * jruby-1.7.19 [ x86_64 ]
   jruby-1.7.20 [ x86_64 ]
   jruby-1.7.21 [ x86_64 ]

   ruby-2.2.0 [ x86_64 ]
   ruby-2.2.1 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

Hope this helps others!

Resonant Rise 3 Java Settings to reduce lag

I've begun a new Youtube series covering Resonant Rise 3 (
In the process I discovered it lags.

As my Linux server decided to sulk and fail to boot, I'm using a late model Mac Mini as a server.
The clients are late model iMacs.
I'm organising a replacement linux server which I will use in our upcoming videos.

So I did a metric shit ton of digging and finally found a series of settings for the server and client that reduce that lag considerably.
You keep getting:

"Can't keep up! Did the system time change"


Then do this.

On your servers

set -x
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home
export PATH=${JAVA_HOME}/bin:${PATH}
opts="-server -XX:+TieredCompilation \
-XX:-DontCompileHugeMethods \
-XX:+UseCodeCacheFlushing \
-XX:ReservedCodeCacheSize=256m \
-XX:+UseBiasedLocking \
-XX:BiasedLockingStartupDelay=0 \
-XX:NewRatio=3 \
-XX:+UseParNewGC \
-XX:+UseConcMarkSweepGC \
-XX:+DisableExplicitGC \
-XX:+CMSIncrementalMode \
-XX:+CMSIncrementalPacing \
-XX:+CMSParallelRemarkEnabled \
-XX:+UseCompressedOops \
-XX:CMSInitiatingOccupancyFraction=30 \
java -Xmx2G -XX:MaxPermSize=256M $opts -jar forge-1.7.10- nogui

(Slashes added for readability)

Of course this assumes you're using Java 1.7 update 71.
I tried JDK 1.8 and it gave me a whole bunch of grief.
So I decided to switch back to JDK 1.7 and see if that helped.
It did.
Suddenly the Mac Mini used all 4 cores instead of just 2 and the client side (iMac) sped up considerably.

Ok. Now client side.
In the ATLauncher settings, choose 'Settings' and:

For the Java path use: /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home
(Again assuming you have 1.7 update 67 - change to suit)

And for the Java parameters:

-server -XX:+TieredCompilation \
-XX:CompileThreshold=1500 \
-XX:-DontCompileHugeMethods \
-XX:+UseCodeCacheFlushing \
-XX:ReservedCodeCacheSize=256m \
-XX:+UseBiasedLocking \
-XX:BiasedLockingStartupDelay=0 \
-XX:NewRatio=3 \
-XX:+UseParNewGC \
-XX:+UseConcMarkSweepGC \
-XX:+DisableExplicitGC \
-XX:+CMSIncrementalMode \
-XX:+CMSIncrementalPacing \
-XX:+CMSParallelRemarkEnabled \
-XX:+UseCompressedOops \
-XX:CMSInitiatingOccupancyFraction=30 \

(Slashes added for readability)



I'm still hunting for "The Perfect Seed" for videos, and will get back to making videos as soon as my current IRL workload decreases.

Where does chrome store open tabs information?

Recently I had a problem with a upgrade from Mavericks to Yosemite.
The upgrade failed.
But I had backed up all the main folders I might need in case of such a folder.

For reference, these are:

- /private
- /Library
- /Applications
- /Users/my_home_folder

I had to burn the machine and install Yosemite from scratch.

Now one of the things I wanted to recover was the current tabs I had open in Chrome.
The reason being was that some of them were very, very interesting and I had not bookmarked them.

I did a little bit of research, but not much turned up.
So I figured it out myself.

Let's say you have a folder ~/OldMachineBackup and it has the folders mentioned above in it.

So to find out what tabs you had open:

cd ~/OldMachineBackup
strings Application\ Support/Google/Chrome/Default/Current\ Tabs | egrep '^http' | sort | uniq

And there you have them. A list of http addresses.

Upgrading the docker service from 1.3 to 1.5 on Ubuntu 14.04

Recently I had to upgrade a production server to ensure it was running the latest version of docker (1.5.0 at time of writing).

The current install was 1.3.1 and we wanted all docker servers to be identical.

First up, assume you have done a sudo -i to ensure all commands are run as root.

Also, some commands are prefixed with $ . This is to identify the command from it's output.

And further, I have used bogus IPv4 addresses for certain URLs.

For reference, I used as the docker server IP.

Thank you Dr Mark Courtney and Dr Paul Murphy and all the staff at John Flynn Hospital

Ok. I survived my latest surgery. Many thanks to the staff of John Flynn Private Hospital and Dr Mark Courtney and Dr Mark Murphy for making it memorable.

I say memorable in that my handbag and overnight bag got lost. I'm not complaining mind you.


6 hours of searching by security staff eventually found them. Keys, cards, prescriptions, etc basically 2/3rds of my life recovered. Thanks guys!

In the mean time I had to wear paper clothing and be restricted to my room. Which was awesome I have to say. Fantastic views. But no underwear. Sucks to be me. Dr Courtney came round to see how I was faring at 7:30pm. Way, way, seriously way, after his visiting times.

Now that's dedication to doing the right thing.


He was an angel and sent me home rather than stay overnight because:

1) The cyst (huge bugger as it was) was easy to remove and
2) I didn't bleed like a stuck pig and
3) He understood I had to pay for the room out of my own pocket and
4) ALIENS! No. Not really. Just people. Humans. Good humans.
5) Now where did I put number 6?
6) Oh! Here it is!

I shook his hand warmly and gave him a hug. He positively beamed happiness.

And a big shout-out to Dr Paul Murphy.
We had met before and I kept calling him 'Paul'.
Kinda odd in a professional kind of way.
I kept expected him to say

I didn't spend 3 years in "evil Anaesthesia College" to be called "Paul" thank you very much. It's Dr Murphy if you please.
Sorry about that.

Oh. I have to mention. While in pre-op I overheard the birth of two babies. AWESOME. Made me smile. And many of the staff I have to say. Cool.

I now have a HUGE plaster on my neck and my neck hurts like... Like... Buggery... But I have antibiotics, pan forte and FINALLY have this damn thing out of my neck. Two years of coughing myself to distraction every morning for 2 hours. Gone. Clicking when I swallow. Gone. Glands the size of golf balls. Gone. Finally. Gone.

Thank you Dr Mark Courtney and Dr Mark Murphy and all the staff at John Flynn Hospital for making it go away. Thank you.

And A massive shout out to security for ransacking every ward and every locker for my bags.

Thank you.

Dr Courtney.
Dr Murphy.

Docker: Find what the container port is from inside the container!

Ok. Service registration and discovery inside a docker container can be fiddly sometimes.
And I wanted to have dynamic port numbers when starting a container so I could 'register' the service in Redis.

So how do you do it?

I first fiddled with using socat inside the startup for the service which worked, but was ugly.

FYI: I ran up a vagrant ubuntu VM and installed docker 1.5 to test this.

So here's the way to do it in ruby.

# ---------------------------------------------------------------------------
# Find out what our container port is
# ---------------------------------------------------------------------------

SVC_NAME = 'api-dummy_1'

require 'socket'
require 'net/http'

# Create the socket to the docker host
sock ='/var/run/docker.sock'))

# Go grab all the containers details
request ='/containers/json')
request.exec(sock, '1.1', '/containers/json')
  response = Net::HTTPResponse.read_new(sock)
end while response.kind_of?(Net::HTTPContinue)
response.reading_body(sock, request.response_body_permitted?) { }

# Parse and loop over it trying to find our name
data = JSON.parse(response.body)
puts "Data received: #{data}"
data.each do |container|
  puts "Looking at: #{container}"
  if container['Names'].include? "/#{SVC_NAME}"
    container_port = container['Ports'][0]['PublicPort']
    puts "CONTAINER_PORT: #{container_port}"
    ENV['SVC_PORT'] = container_port.to_s

Obviously you'd have to do something to handle it if you can't find the name...
And should really check the Ports array better.

The socket call returns an array something like this:

  "Command":"/bin/sh -c 'bundle exec foreman start'",
  "Status":"Up 1 seconds"
  ...another one...

You have to map the /var/run/docker.sock on running the container of course.
Something like this:

export SVC_NAME=api-dummy_1
export DOCKER_HOST=tcp://
export REPO= # Whatever
docker pull ${REPO}:5000/something/${SVC_NAME}
docker kill ${SVC_NAME}
docker rm ${SVC_NAME}
docker run -d --env RAILS_ENV=production \
              --env HOST_IP= \
              --env SVC_NAME=api-dummy_1 \
              --env REDIS= \
              --name ${SVC_NAME} \
              -p :5000 \
              -v /var/run/docker.sock:/var/run/docker.sock \

Names and IPs to be changed of course.

Still fiddly, but it works.



I just realised that docker provides a HOSTNAME environment variable which is essentially the container id which would allow you to call /containers/#{ENV['HOSTNAME']}/json instead of doing the loop to get the configuration for that specific id.

Diamonds For Nothing a parody for Minecrafters

Now look at them diggy-diggies that's the way you do it
You play the pick-axe on the MC-YT
That ain't diggin' that's the way you do it
Diamonds for nothin' and chickens for free
Now that ain't diggin' that's the way you do it
Lemme tell ya them miners ain't dumb
Maybe get a arrow on your right arm
Maybe get a arrow on the back of your head

We gotta install these coal-powered ovens
Custom jukebox deliveries
We gotta move these iron bars
We gotta move these chestie's

See the little noob with the skin and the hat
Yeah buddy that's his own hat
That little miner got his own jet pack
That little miner he's a millionaire

We gotta install these coal-powered ovens
Custom jukebox deliveries
We gotta move these iron bars
We gotta move these chestie's

I shoulda learned to play the game
I shoulda learned to play them picks
Look at that miner, she got it stickin' in the camera
Man we could have some fun
And he's up there, what's that? Indie noises?
Bangin' on the creepers like a simoneeze
That ain't workin' that's the way you do it
Diamonds for nothin' and chickens for free

We gotta install these coal-powered ovens
Custom jukebox deliveries
We gotta move these iron bars
We gotta move these chestie's

Now that ain't diggin' that's the way you do it
You play the pick on the MC-YT
That ain't diggin' that's the way you do it
Diamonds for nothin' and chickens for free
Diamonds for nothin' and chickens for free

I want my
I want my
I want my MC-YT!
