Time Travel Debugging

Time Travel refers to the ability to record a tab and later replay it ([WebReplay][wrr]). The technology is useful for local development, where you might want to:

• pause and step forwards or backwards
• pause and rewind to a prior state
• rewind to the time a console message was logged
• rewind to the time an element had a certain style or layout
• rewind to the time a network asset loaded

I was reviewing some documents on the graalvm and its truffle languages and it occured to me that one could write a go ast to LLVM IR emitter. Go has pretty good support for ast operations, thus it looked feasable at least. Obviously next thing I did was to check and see if someone had already done this. And yes.There is a project doing exactly that.

The support for the language is not all there yet and honestly I don't think this is the most sustainable approach but it was fun to play with it. I got some minimal go(tre) code running through graal's lli pretty fast

Ingredients

• Install GraalVM, and then set your PATH so that you get the GraalVM binaries
• llvm (brew install llvm)
• go install github.com/zegl/tre/cmd/tre

Ghydra decompiler

This python script communicates with the Ghydra decompiler. Currently it succeeds in communicating, sending hardcoded opcodes and returning decompiled code.

Currently working on reversing the getPcodePacked command.

Next steps:

• implement exception handling
• implement callbacks
• allow decompilation of custom payloads

关于 URL Scheme 你知道多少？

iOS 系统中

由于苹果的各应用都是在沙盒中，不能够互相之间访问或共享数据。但是苹果还是给出了一个可以在 APP 之间跳转的方法：URL Scheme。简单的说，URL Scheme 就是一个可以让 APP 相互之间可以跳转的协议。每个 APP 的 URL Scheme 都是不一样的，如果存在一样的 URL Scheme，那么系统就会响应先安装那个 APP 的 URL Scheme，因为后安装的 APP 的 URL Scheme 被覆盖掉了，是不能被调用的。

Android 系统中

How to run a GUI application as a different user:

Suppose you are logged into your Linux box as user1 using some X window system already (with GNOME/Unity/..). Now you want to run some gui app as another user, user2.

Run:

1. xhost + - Run as the user1. This enables access to user1's X window system from other users. You should see following output: 'access control disabled, clients can connect from any host'
2. sudo su - user2 - Using your favorite terminal, log-in to second user.
3. export DISPLAY=:0.0 - optional for some apps.
