I've been trying out @stripe's Treasury feature and ordered a card for business expenses. It arrived today and I didn't expect it to be metal 👀 The UK card design seems different from the US version.
TIL: A UX tip for better managing UI states across tabs or frames.
@nextauthjs uses `BroadcastChannel` to synchronize the authentication state across them.
Besides the UX tip, `BroadcastChannel`'s polyfill can be implemented by leveraging `localStorage` and `storage` event.
haha... it's time to change the background! raw.githubusercontent.com/cl….

After 48 hours of hard work, thanks to @paradigm_ctf for hosting such an amazing CTF challenge. Time to ramp up my cryptography knowledge this year!
Goal for next year: Top 10 !!!
SHOUT OUT TO my incredible teammates, @paco0x and @twxia!
TIL: when using zsh, put the below setting into the `~/.zshrc`.
```
setopt HIST_IGNORE_SPACE
```
By using a leading space, you can bypass zsh to record the sensitive data in `~/.zsh_history`
TIL: Discord removed localStorage property from window in 2018 for preventing social engineering attack to steal user’s jwt token. Pretty cool way. However, localStorage still retrievable by using a tricky technique. stackoverflow.com/questions/…
This is another level of analogy. Didn't expect that my rusty electrical engineering knowledge is useful at this moment.🤯

TIL: I can use #yubikey as my TOTP (Google Authenticator) backup plan. Secrets can be stored inside my #yubikey (at most 32 codes). Don't need a backup code or store code at @Authy. Once I broke my phone, I could still get them from my🔑 (how it works? developers.yubico.com/OATH/)

Here's my favorite git feature that no one knows about:
You can reference commits using the commit message instead of the hash. The ":/" syntax accepts a regex that matches any part of the commit message, returning the youngest matching commit.

Tip: You can name capture groups for Regular Expressions in JavaScript. Define a named capture in angle brackets <> and they get returned under .groups.

New post 🆕 Record tests with the puppeteer recorder built right into DevTools (experimental)

Helpful for scaffolding out code which would otherwise be tedious to write.

PRO TIP: Check the vault's funds before the withdrawal. If the amount withdrawn is less than the vault's idle funds, there's no 0.5% fee.
The 0.5% fee logic is inside the strategy.
👇vault's code
r = the amount withdrawn by you
b = vault's total amount
(not the yvault's token)
