Makerhaus Laser Cutter Notes.

10.25.2015

For about a year, I was a member of MakerHaus, a maker space which was reasonably convenient for me. Alas, they closed last year, shortly atfer I had taken the class to become certified to use their laser cutter. Since I am eagerly awaiting my Glowforge laser cutter, I thought I'd share my notes from that class. Note that while the general concepts should apply to the Glowforge, these notes were originally for a unknown laser cutter: shown in this video.

The depth of the laser's cut is a result of the combination of power, speed and material. Run a test grid of speed and power combinations to calibrate materials.

Materials

Maximum size is defined by cutter; 46" x 34" in this case.

Acceptable materials (and their max thickness)

Sublime Text Preferences.

10.15.2015

Getting the perfect configuration set up is part of what makes Sublime Text a dream. Here are some of the most useful configuration changes (from Sublime's defaults) that I've found. You can set these by editing the preferences file at Preferences > Settings - User.

"afn_insert_dimensions": "false"
With the AutoFileName package, don't automatically insert image dimensions.
"bold_folder_labels": true
In sidebar, show all folders with bold font.
"caret_style": "phase"
A smoother cursor blink transition.
"close_windows_when_empty": false
Don't close Sublime Text when there are no open files.
"copy_with_empty_selection": false
Don't copy if nothing is selected.
"ensure_newline_at_eof_on_save": true
Be sure all saved files end in an empty line.
"fallback_encoding": "UTF-8"
Use this encoding when it can't be determined automatically.
"file_exclude_patterns": [".bak", ".DS_Store", "Thumbs.db"]
Don't show these files in the sidebar or GoToAnything.
"find_selected_text": true
"Find" field is pre-seeded with highlighted text in document. Keeping this in user preferences ensures it works on OSX.
"folder_exclude_patterns": [".git", ".sass-cache", "tmp"]
Don't show these folders in sidebar or GoToAnything.
"font_options": ["subpixel_antialias"]
Prettier text.
"highlight_line": true
Use a lighter background color for line where cursor is.
"highlight_modified_tabs": true
Use special color for tabs with unsaved changes.
"line_padding_bottom": 1
Add just a little white space below lines.
"line_padding_top": 1
Add just a little white space above lines.
"open_files_in_new_window": false
Whether OSX opens dragged-in files in a new Sublime window.
"show_full_path": true
Whether title bar shows entire file path instead of just name. Keeping this in user prefs ensures it works on OSX.
"tab_size": 2
How many spaces is a tab equal to?
"translate_tabs_to_spaces": true
Use spaces instead of tabs.
"trim_automatic_white_space": true
Removes any auto-indented whitespace when on new lines.
"trim_trailing_white_space_on_save": true
When a file is saved, delete any whitespace at the end of a line.
"wide_caret": true
Have a wider cursor marker for better visibility.
"word_separators": "./\\()\"':,.;<>~!@#$%^&*|+=[]{}~?"
Make it so that dashes et cetera are considered part of a word; and thus don't break a selection with a class name, for example.
"word_wrap": "false"
Set word wrap to by default for all file types / syntaxes. Can still enable / disable word wrap via View menu. I don't know why this "false" has to be a string, but it does.

10.5.2015

(I'm a few days late in marking this anniversary. What can I say - I've been busy. Heck, I've had a full plate for a year now, which is the point of this blog.)

One year ago, I gave my first conference talk at SassConf 2014. My 10 minute lightning talk "Color In The Real World" was about how we perceive color, how artists use tricks with color for realistic effects in paintings, and Sass color functions can replicate those tricks.

A little over a month later, I gave a 45 minute talk "From 0 to Nodebots" at the inaugural Nodevember 2014. Though I had been submitting talks to conferences for more than a year, this was my accepted talk. This was an expanded version of the talk I had given at my local JavaScript meetup a few months previous.

In March of this year, I presented "Colour in the Real World" at CSS Conf AU in Melbourne, Austrailia. This talk was an expanded version of my SassConf talk, and is another talk that was accepted via CFP.

In May, I was invited to JSConf US in Florida to help with the NodeBots event. This invitation was a result of the video from my Nodevember talk. Having a public video of their talk is a great artifact for a speaker, and for your community.

In July, it was finally time for Cascadia Fest. Way back in January, I'd been invited to join the core organizing team and curate Browser JavaScript day. So since then, I'd been brainstorming party and workshop ideas, reading proposals and selecting talks, and writing tons of emails and Slack messages. After having attended 2 previous CascadiaJS conferences, I got involved by starring the CJS Github repo and volunteering to help with a smaller part of the conference.

And a week and a half ago, I closed out an amazing year by presenting "Developing for Localization" (a completely new talk) at CSS Conf EU 2015. I was particularly delighted to have my CFP accepted here because CSS Conf EU is so prestigious and competitive. I finally had the opportunity to attend JS Conf EU too!

Looking back at this past year, I feel so thankful to have had such great opportunities and be a part of all of these events. I've promised myself that I could tone down the events next year, and I really am savoring the idea of some quiet time. I'll finally able to work on some long neglected "for fun" projects, and maybe just relax a little bit.
