I wanna say this before everything burns down, we built something special. Everyone I know who worked @Twitter cared so much about the users of this platform, about using it to make the world better, and it wasn’t perfect but we tried our fucking hardest and it was good.

[Ken Kocienda @kocienda]

No. This is false. I helped to create two different billion-user projects at Apple: WebKit and iPhone. I was on these teams from the earliest stages and I never once came close to sleeping at the office. It’s not an essential part of doing great work.

i think
- what Twitter built is amazing;
- they didn’t get enough credit for it;

I’m amazed at ppl who’ve never built a product that are convinced they’d PM twitter better.

Ppl add twitter handles to their business cards && bylines.

World denting is hard, and they did.

Check out Enclaver, the first open source project from @EdgebitIO. Securing data "in-use" is now essential for cloud services.
Enclaver enables easy adoption of secure enclaves with a familiar UX – like running a container, but it’s actually running within an AWS Nitro Enclave.

“hacked messages are also believed to have included highly sensitive discussions with senior international foreign ministers about the war in Ukraine.” Obvious question is why was she using personal phone for top-secret conversations? https://t.co/ynzi5Pv8Ac

One of the best ASO experiments I had was to increase the font size on screenshots to make them readable in app store search results. 10.83% -> 14.78% from impression to install. #buildinpublic #aso #indiedev

We just launched a mobile ecosystem survey, and we’d love for you to participate! We will share out the analysis publicly via https://t.co/LNdApU84GU. Make sure you’re building for the future by taking a few minutes to fill it out now! 🎉 https://t.co/cx0CvOsHSp

Jerry’s apartment hallway can’t exist. My entire childhood was a lie.

[Scott Berrevoets @ScottBerrevoets]

We’re a few years into technological decision-making for our mobile codebases so I wrote a little bit on how my thinking has shifted from primarily technical to how people will interface with new technologies.

At @SpotifyEng we’ve been experimenting with @bazelbuild macOS remote execution over the last year. A few weeks ago we enabled it for our main iOS CI build and decreased our p95 by almost 5x with a cluster of 60 M1 machines. Very impressive stuff!

[Oskar Groth @oskargroth]

Oof. macOS state restoration data was serialised without secure coding, so injecting malicious code into windows.plist and tricking system apps to load it would escape the sandbox & grant root privileges. https://t.co/ANaosMWnnY

My favorite bug among the vulnerabilities I presented today! 😆

The original intent was to compare the password. However, the developer copy-and-pasted the code but forgot to replace the variable name. That leads to the Authentication Bypass on IIS.

[JP Simard @simjp]

With the latest SwiftLint release candidate, you can now develop custom native SwiftLint rules in Xcode right from your private projects. 🤯
