⌘ Very‧Short‧Cuts

Quickest way to serve the current folder as webserver ever.

iOS Screen Recording using Quick Time

Quick Time is the easiest way to do a quick screen capture of your iOS device. You only need to connect it with cable to your Mac and launch Quick Time ‣ File ‣ New Movie Recording ‣ Select iPhone/iPad as source. Here are some additional shortcuts to save some time on the way.

Keyboard shortcuts

After launching Quick Time.

⌃+⌘+n Start New Screen Recording

␣ Record

App shortcut using Automator

With Automator you can create a little app shortcut that launches directly into "Movie Recording" mode. Unfortunatelly the source selection is not exposed here, so there's still one last necessary to select your iOS device using the drop down.

Colors App Palette Management

The Mac OS X color picker is a great place to store and access color sets. While this is not exposed in the app itself it is possible to save and re-use palettes.

Copy and add saved palettes

Look out for .clr files

~/Library/Colors

Apple Watch Palette

To get started here's the Apple Watch default color palette as referenced in the Apple Watch Human Interface Guidelines

Download Apple Watch Color Palette

Open OS X Color Apps

In order to open the colors utility as a stand alone app you need to create a little launcher script using the AppleScript Editor under Applications > Utilities > AppleScript Editor with the following command

choose color

make your script executable

chmod +x scriptfilename

Check your current "PATH" folders

echo $PATH

Go to one that makes sense e.g. /usr/local/bin

cd /usr/local/bin

create a symlink

ln -s ~/scripts/scriptfile

Download image (iso)

Convert iso to img

hdiutil convert -format UDRW -o FreeNAS-9.3-RELEASE.img FreeNAS-9.3-RELEASE.iso

Check for disk path of USB media

diskutil list

Copy image (to disk at e.g. /dev/disk2)

sudo dd if=FreeNAS-9.3-RELEASE.img of=/dev/disk2

To have Korg Volca Beats listen to an external Midi clock, you need to enable Midi Sync Mode. Here's how to do this:

Press Func while powering on

Enable pad 6 (red light)

Press Rec to confirm

You can double check if the setting is enabled turning the "Tempo" knob. If the external Midi Sync is enabled the display won't show any tempo change.

Here are the MIDI note mappings for the GarageBand drum machine instrument.

My goal was to use the LPD8 as drum trigger for GarageBand. I connected it using the USB Camera Connection Kit.

→ Download my LPD8 controller editor preset here

The sad part: Having all set up and mapped it turned out that the LPD8's latency is (conspiracy theory: intentionally?!) too poor in order to use it for live drumming. Nice for playing around for a couple of minutes but nothing you would want to use on stage. Anyhow, I am sure want to try that out on your own. This should make it easy. The details:

Knobs

K1 – Volume

K5 – Pan

K2 – Send to Echo

K6 – Send to Reverb

Pad Layouts

Preset 1 – Preset optimized for live drumming

Preset 2 – Preset analog to the iPad grid

General CC mappings for GarageBand Source

CC#3 - Track Solo * CC#7 - Track Volume CC#9 - Track Mute * CC#10 - Track Pan CC#28 - Echo Send Level CC#29 - Reverb Send Level CC#59 - Effect 1 on/off * CC#60 - Effect 2 on/off * CC#61 - Effect 3 on/off * CC#62 - Effect 4 on/off * CC#63 - Effect 5 on/off * *meant for buttons

Here's the quickest way I know to get running with a clean MySQL installation for local web serving

Have Homebrew installed

brew install mysql

Have Sequel Pro installed

Create new connection using

Host: 127.0.0.1 User: root

Some things have changed in Apache since 10.8. Here's how to get the web server running again in Yosemite.

Apache

Edit /private/etc/apache2/httpd.conf

Add

<Directory /> AllowOverride none Options +Indexes </Directory>

Uncomment

Include /private/etc/apache2/extra/httpd-vhosts.conf

Oh, and while we're here, why not also enabling php for our old Wordpress … uncomment

LoadModule php5_module libexec/apache2/libphp5.so

Add local directory to /etc/apache2/extra/httpd-vhosts.conf

<VirtualHost *:80> DocumentRoot "/Users/Aww/Web-Projects/public" ServerName web.local </VirtualHost>

Add local address to vhosts /etc/hosts

127.0.0.1 web.local

Restart Apache

sudo apachectl restart

if anything goes wrong, check the log files at /private/var/log/apache2/

Permissions

In case you get a 403 error surfing to web.local you will need to fix your permissions, e.g. like this …

◳ Context click on file ‣ Open Terminal Here …

⇧ + ⌘ + t Open Terminal at location of selected file/folder

⇧ + ⌘ + ⌥ + t Open Terminal at project root

This comes pretty handy especially for Wordpress Templates with embedded php code. Instead of messing up your template file with the extended version

<?php echo "pain"; ?>

you can also use

<?= pain ?>

Here's the blue print for a simple Automator application. Drag multiple image files on the application icon to turn them into pages of one PDF document.

When you add a git folder folder into git folder folder - as you might do for using other open source libraries in your code - you'll find that the .git meta folders will interfere with each other. If you want to keep all libraries attached to their respective git origins you need to add them as Submodules. The difference is that those submodule library folders need to be treated independently from your own code. You need to initialise and fetch their content separately. Here's how it works.

Add a git folder as submodule (instead of simply cloning it into your existing git folder = bad), example ...

git submodule add [email protected]:MrRio/jsPDF.git jsPDF

Go to the folder of this library. You'll find it's still empty. Init and Fetch its contents

git submodule init git submodule update

That's it. Now you can commit and publish your own topmost folder while keeping the references to the other containing git repositories intact.

aka the first aid kit for fixing Wordpress server permissions issues. Let's have a look ...

Users

List users

cat /etc/passwd | cut -d: -f1

Add user

useradd -m username

List users and their groups

getent passwd | awk -F: '{print $1}' | while read name; do groups $name; done

Extensive version. Users, groups, home directories, stuff ...

getent passwd

Assign user to group

usermod -a -G groupname username

Groups

List groups

cat /etc/group

Add group

groupadd groupname

Permissions

List permissions of contents of a folder

ls -l

Change user owning a file/folder

chown user file.txt

Change user owning a folder and all its content

chown -R user directory/

Change group owning a folder and its content

chgroup -R groupname folder

Debian

chgrp -R groupname folder

Change permissions to include only the owning user

chmod -R 750

or the user + group (depending on your preferred permissions setup)

chmod -R 770

Wordpress

If your Wordpress runs into write permissions issues on a new server here's your potential path to fix this.

Figure out the user name your web server process runs on

Check the set user + group permissions of your wp-content/uploads folder

Either make sure that your web server process is owner of this and all containing folders or part of the group assigned to the same

Rectify permission accordingly - if that's the issue
