The latest Signal beta includes some changes to the way safety numbers work. Back in November, we introduced experimental support for "advisory" safety number changes, with the objective of collecting feedback in order to eventually make this the default experience. We've taken the feedback we've re...

No Risk No Reward

After immersing myself for years and years in the world of finance (specifically, options market making and algorithmic trading), there was no escaping this mantra of "no risk, no reward." Most of the time, my (trading) style was fairly risk averse. I knew how to find the signals of opportunities am...

Paddle Out

Winter Break Of Code Day Eighteen Late this afternoon I took a break from working to surf. The sun was setting and a cool breeze was picking up as grey clouds billowed behind the mountains along Hanalei Bay. I had spent most of the day wrangling content, markup, and CSS, and the Pacific was calling....

Mutiny!

Winter Break Of Code Day Seventeen In this life nearly every relationship we create and maintain is built upon expectations. You do this, I'll do that, and together we'll fail to oppose entropy but stand a chance at plotting and navigating a loose course through it. These expectations extend beyond...

Naked

A post from Natalie, Winter Break Of Code, Day Sixteen Today, I watched sunlight dance atop billowing waves, a natural circus spectacular. I meditated on two syllables, allowing my breath and heartbeat to synchronize, and I too became a part of the show. Read more...

Real World Kauai

Winter Break Of Code Day Fourteen When I agreed to take part in Winter Break of Code, I had no idea what to really expect.

There's no you in srveillance

Winter Break Of Code Day Thirteen My ten-year-old mind was completely blown when I realized that I could eavesdrop on the walkie-talkie conversations of the other kids in my neighborhood. I rode my bike to the library in stunned silence, found a book about codes and puzzles, and raced home to my com...

Mahalo

Winter Break Of Code Day Twelve A few days ago, someone suggested that we go scuba diving and I said “yeah sure, that sounds fun”. Once we actually got to the dive site I realized I had no clue what I signed up for. I was scared out of my fucking mind, squirming against the ocean’s currents, and con...

Aloha But Not

Winter Break Of Code Day Eleven Every morning at standup I’d watch the knife spin in slow motion, dread filling my chest and a voice in my head repeating, over and over, “not Slytherin.” (The target of the knife is the author of the next day’s blog post). I wasn’t sure that I could find new ways to...

A curve by any other name

Winter Break Of Code Day 7 Yesterday was a day of meetings. Discussion and debate flourished. Conversations ranged over all parts of every project. Words spoken aloud may have outnumbered lines of code shipped. The entire team was fully engaged and, people nearly had to be dragged out of the house f...

Signal to Noise

Winter Break Of Code Day 4 I'm not sure those attending their first break of code know what they are getting into. When I said "sure" to Moxie my first break, I sure didn't . During that week I had already come to the conclusion "I have to see this (TextSecure iOS) through". In the intervening time,...

Third Day Of Code

Winter Break Of Code Day 3 As it does every morning, the day started with moxie singing the standup song, reminding us all (and waking up the slackers) that at 9am sharp we all get in a circle to discuss what we accomplished the day before and what our priorities are for the coming day.

Star Quality

Winter Break Of Code Day 2 Because I might get sappy, here's a picture to ease that before I let it all out. After being promptly woken up by numerous roosters at 7:30 AM, I still can't believe I'm here. My application was pretty last minute, completed when I was in a state of droopiness and scholar...

Private Group Messaging

One of the major features we introduced in the TextSecure v2 release was private group chat. We believe that group chat is an important feature for encrypted communications projects, so we wanted to try to summarize some of the existing work in this area, as well as how TextSecure's group chat proto...
