Hey! Are you going to Build? We should hang out.

Let's grab a coffee, chat over lunch, and take some of our sweet Merge Conflict stickers!

Sunday

8 - 10AM: COFFEE with James at Espresso Vivace (Alley 24 by REI)

Monday

12 - 1PM: LUNCH with CDAs/Xamarins: Find our cool signs in the lunch area
2:00 - 2:20 PM: SESSION THR2438 Start building mobile apps in 5 minutes with Xamarin Live Player

#Installing ngrok on OSX

Download ngrok
Unzip it to your Applications directory
Create a symlink (instructions below)

Creating a symlink to ngrok

Run the following two commands in Terminal to create the symlink.

# cd into your local bin directory

If you have already taken a course in algorithms, why read Grokking Algorithms (manning.com/bhargava)?

If you were learning graph algorithms, which approach would you prefer:

Imagine you have to take public transit from your home to your office. How do you figure out the fastest route? Use graph algorithms! OR
We can choose between two standard ways to represent a graph G = (V, E): as a collection of adjacency lists or as an adjacency matrix. Either way applies to both directed and undirected graphs.

I prefer the first way: lead with lots of examples, and clear writing. The second way is an excerpt from "Introduction to Algorithms"...that's how they start their section on graph algorithms.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
