I developed Cydia for jailbroken iOS devices, was a (local) politician in California, and focus on security issues for decentralized computation and networking.

Last week, I discovered (and reported) a critical bug (which has been fully patched) in @optimismPBC (a "layer 2 scaling solution" for Ethereum) that would have allowed an attacker to print arbitrary quantity of tokens, for which I won a $2,000,042 bounty.

Substrate 0.9.7000 is my most well-tested update ever, verified to work on iOS 3.0, 4.3.1, 5.1.1, 6.1.3, 7.1.2, 8.0, 9.0.2, 10.1.1 (mach_portal), 11.1.2 (Extender), and 11.3.1 (unc0ver). I expect it will fail anyway :(. If you want to try it, add apt.saurik.com/beta/substrate… to Cydia.

Hi @tim_cook. iOS is the *only* major platform which not only pulls VPN apps from its market but also requires users to "enroll" and pay $100 a year to use the VPN APIs locally. As far as I'm concerned, you are directly supporting authoritative regimes :/. news.ycombinator.com/item?id=147353…

(I have now spent over a decade working on Cydia and fighting against Apple's harmful platform control. In these years, I have never once reached out to either Steve Jobs or Tim Cook... until today... and I seriously managed to type "authoritaTIVE" instead of "authoritaRIAN" ;P.)

Cydia just joined the legal battle against Apple: "A new lawsuit brought by one of Apple's oldest foes seeks to force the iPhone maker to allow alternatives to the App Store, the latest in a growing number of cases that aim to curb the tech giant's power."

About two weeks ago, Apple made a change to their provisioning service to require a different authentication scheme for "free" Apple accounts (they return an error that mentions upgrading to "Xcode 7.3"); this broke Cydia Impactor for users without a paid Apple Developer account.

For those who dare to experience @qwertyoruiopz's "unstable/glitchy" beta jailbreak IPA for iOS 10.0-10.1.1, Cydia Impactor 0.9.35 is ready!

Truly, jailbreaking should have stopped during the iOS 9 era, if not before; there is a reason essentially all of the reasonable developers left long ago and the community is largely now run by bullies. Everything that we do now just digs jailbreaking a deeper hole, full of fail.

A few days ago, Epic Games filed a lawsuit against Apple, challenging the idea that the Apple App Store--with its high fees and limitation on promotion of anything that isn't an Apple product or payment mechanism--is the only way to distribute apps on iOS. cdn2.unrealengine.com/apple-complain…

Cydia Impactor 0.9.43—an update *for Windows only*—fixes the "Peer certificate cannot be authenticated with given CA certificates" error :(.

I am the only commissioner at the #CALAFCo (California Association of Local Agency Formation Commissions) 2019 Annual Conference here representing the United Federation of Planets! I was a bit saddened to not see a regional round table for the Alpha Quadrant :(. #Halloween2019 🎃

In the mean time, I owe nobody anything and nothing I have would help anyone anyway (and particularly won't help anyone trying to support A12). I really wish everyone would just forget Cydia exists and move on with their lives; anything would be better than dealing with all this.

So far, I've only had a few days to work on A12 Substrate (something I couldn't even start doing until a few weeks ago, when I was given the first jailbreak build useful for testing with). I do not understand why anyone thinks I am able to spend all of my time on this anymore :(.

Today, Cloudflare made WARP, their VPN service with an unlimited free tier, available to everyone; it only has clients for iOS and Android, but the protocol they are using seems to be off-the-shelf Wireguard, so you can connect from macOS! Run this script: cache.saurik.com/twitter/wgcf.sh
