Floor plan

This is the floor plan of our venue:

full-size image

The Golden Gate Room is the main room where we all will be sharing, talking, and teaching each other about RubyMotion. There is a pretty good size screen behind the stage. The ceiling is very high and the room will easily hold all of us. It has windows on three sides. On the right side it looks out over boats then to the Golden Gate Bridge. Here is a photo:

image

The Marina Room is where we’ll have food, drinks, and a place to hang around. It can hold upto(80) people sitting.

The Bay Room will be where the speakers can setup. The Foyer is a decent size, it has room for tables and such. There is also a very small kitchen.

Outside, we get a slab of concrete with picnic benches on it (8 of them IIRC). Plus the marina with the boats is right next door:

We can serve alcohol here, which means we don’t need to travel somewhere else for our after-party. We’ll have other refreshments for those not drinking alcohol.

Food


You’ll get breakfast and lunch both days, so no need to get your own. We’ll also have coffee and tea (I think it’s pretty good coffee too, it’s suppose to be at least; we’ll find out)

Parking


Try to walk, take the bus, or Uber over to the conference (never tried Uber? it’s awesome). SF is small, you can walk places pretty fast.

Bike racks are located throughout Fort Mason.

There is limited parking at Fort Mason, it’s not free ($10.00 a day).

There is parking outside of Fort Mason, but it’s often full, and you can’t park there all day:

RubyMotion News


RubyMotion 2.28 released

  • Added support for BigDecimal'. This class is implemented on top ofNSDecimalNumberand currently adds all theBigDecimal’ operator methods. It can be passed to APIs that require NSDecimalNumber *, NSDecimal, and pointers to `NSDecimal’.
  • Fixed a bug with framework search paths that contain spaces.
  • Fixed a bug with Objective-C methods that expect a void-pointer to an object (id/CFTypeRef) and thus a Pointer. The object is now passed as-is.
  • Fixed a bug with the CoreMIDI BridgeSupport metadata on platforms that have 64-bit support where the MIDI types would be unavailable.
  • Fixed a bug where empty .strings files would lead to a build failure.
  • Fixed a bug which which it could not retrieve NSNotFound correctly as method return value.
  • Fixed a bug which it will trigger a crash when it would call Proc object which is generated by Method#to_proc.
  • Fixed a bug which NSNumber object would not be converted to Ruby Numeric object with Objective-C Subscripting.
  • Fixed a bug which it can’t call super with keyword arguments.
  • Fixed a bug which incorrect cache would be used in internal and it will trigger an exception when shortcut selectors would be used.
  • Fixed a performance issue in deallocating if many objects would be created.
  • Reduced the app boot time. ~15% faster.
  • Improved Object#method_missing performance. ~10% faster.
  • Improved performance in where it would register Objective-C selector. Object#{send, respond_to?} will be ~30% faster.
  • Improved String interpolation performance. ~10% faster.

RMQ News


RMQ 0.5.8 released

This is the last release before v.0.6.0 which will be a major upgrade.

Thanks to all the contributors in this release: @twerth, @squidpunch, @skellock, @shreeve, and @gantman

Important

  • Significant change, this could break your code: Before when you appended, created, or built a view using RMQ it would apply the style you specified in the append command, then call the rmq_build method in the view. This was a bug which I totally missed. I changed it so that it calls rmq_build, then applies the style. This way you can style the view in its own stylesheet, then override it in the controller’s stylesheet.

New features

  • block to .animate to simplify simple animation. rmq(my_view).animate{|q| q.move(l: 10)}
  • append!, create!, prepend!, and unshift! methods. If you don’t need to chain, instead of doing this: @name = rmq.append(UILabel, :name).get, you can do this @name = rmq.append! UILabel, :name
  • swipe_up, swipe_down, swipe_left, and swipe_right to gestures.
  • overriding options for animations
  • absolute_frame to UIView styler, sets the frame relative to the window
  • styler for button title insets
  • added some documentation

Undeprecation

  • Undeprecated weak_ref stuff. (WeakRef still doesn’t work as needed). RubyMotionQuery::Utils.weak_ref(object_here) makes WeakRef usable by libraries (I should make this its own gem)

Bug fixes

  • Fixed some issues with templates (specifically collection view, and view)

  • Fixed distribute :horizontal

  • Misc bug fixes and more tests

For those that are unable to come to the conference

One more week until the #inspect conference, so news is light.

For those of you who can’t make the conference this year, next week will still be exciting for you. Professionals will be recording all the presentations. There are going to be some huge announcements (huge). And there is going to be a lot of new stuff to play with.

Everyone is busy working on their presentations

The #inspect conference is coming in a few weeks, and everyone who is giving a presentation is furiously working on them. I personally haven’t even started, but all is good, I know what it’s going be about.

A few random things I’ve heard from speakers:

  • Can I fly a drone for my presentation?
  • Hey Todd, do you mind if I do a little dig at you in my talk? (my answer was sure. Probably about how I always end my sentences with a higher pitch, kind of the opposite way normal humans do it. I’m sure he actually meant RMQ and not me specifically)
  • Does the projector support HDMI? I need to hook up some devices.

Lastly, we hired a good video team to record the conference, which will be awesome for everyone who can’t physically make it.

RMQ News


I’m still busy working on version 0.6.0, which I plan on releasing before or during the #inspect conference. I made a 5 minute video with a sneak peek of the features, the best part is at the end of the video:

The number of people contributing to RMQ has risen lately, which is exciting. If you use RMQ and want to help out, there are many ways. Just go ahead, or feel free to ask me what you can do.

I spoke to a few people, and they want to help with improving the documentation. It is one place I think RMQ really needs some help.

motion-motion gem, huh?

Conference, gems, community, and Wat

Conference update

First up, the conference is coming soon, tickets are running out, get yours now. If you’re not there, you can’t get one of these cool stickers:

Gems

I’ve started to ask the creators of the “App of the Week” which gems they use. I find this information interesting.

Wat

I’ve renamed “One more thing” to “Wat”, I think that name is a better fit for the “stuff” I stick in there. Gant suggested it, so I stuck his incredibly useful gem in there this week 🙂

Community

MotionKit was released recently, it is a replacement for the aging Teacup. Check it out, I think it’s awesome. Colin and Jamon did a great job.

image

I have this in the community section of my editorial because MotionKit and my library RMQ compete (the layout, subview, and stylesheet parts of RMQ), but I’m very happy to promote the use of it. The other library authors talk about RMQ too. This is why Ruby communities in general and the RubyMotion community is specific are so great, they’re mostly filled with really nice people. I like nice people, and I’m too old to hang around those that aren’t.

FYI, MotionKit should work really well alongside RMQ, but I haven’t tested that yet. Promotion and RMQ work well together.

Hidden Gem by Gant Laborde of Iconoclast Labs


If you’ve come from the Rails world, you’ve probably used an options hash,
and especially used reverse_merge to place your default values.
Unfortunately, reverse_merge doesn’t come from Ruby, it’s a nicety of
active_support/core_ext. You’ll have to just flip it around and use good
old merge.

For reference, if you wanted to do this:

def initialize(opts = {})
    # @options[:number_touches] is only set if the passed hash doesn't have the same respective key
    @options = opts.reverse_merge number_touches: 1
end

You’ll do this:

def initialize(opts = {})
  # @options[:number_touches] is only set if the passed hash doesn't havethe same respective key
  @options = {number_touches: 1}.merge(opts)
end

You can, of course, bring in the motion-support gem, which has reverse_merge,
but I wouldn’t add a dependency for a single method.
