It's the best feeling when your random research project somehow enables other people to build super cool stuff!
Using Apple's Corelocation you can identify network devices in areas where Wigle simply doesn't have coverage.
This is Pine Gap, a joint Australian and United States satellite communications and signals intelligence surveillance base.
You cannot get within 25KM before getting stopped.
Using Apple's own infrastructure you can map out the location of over 140 Fortinet devices on the base.
Is it not possible to train a model with different token spaces for instructions versus data to mitigate prompt injection?
Random thought but what if say tool call responses used a completely different tokenizer so that rather than relying on flaky delimiters?
#showerthought
Or split the embedding space or something. Now that I think about it, someone is probably already doing this...
A quick google and boom: arxiv.org/html/2503.10566v1
What do people think? Prompt injection solved within 2 years?

Never had so many AI products looked so similar
Even though the number of products is exploding, there aren't that many radical new ideas and everything blurs into each other
Every time I open this app it feels like homework: yet another new product to learn that promises to do the same thing but somehow better; the specific ways in which it's better isn't clear unless you invest hours actually trying it
Just found a DMARC bypass for a pretty widely used mail server.
Strong temptations to do some phishing & supply chain attack but obviously can't since we're in America and laws exist here 😭
What if I don't want to talk to another bot. Just shut up and get shit done in the background.
Pipe dream for now, but for how long?
RCE on MacOS dropped. Surprised there weren't any POCs that actually did the RCE.
Everyone just doing file reads and calling it a day (maybe since Claude didn't let them). Well, here you go, a real POC.

人生でもらって一番よかったプレゼント、
熱さまシートのアイマスクです。
このアイマスクつけて寝ると、目を開けたくても何も見えないのでそのまま永遠に寝られるんですが、
一回外したあと「もう一回寝たいな……でも熱さまシート……1枚100円……」となって諦めて起きられます。
不眠症に☆超おすすめ☆
庶民にはちょっと悲しい価格帯です。
坂田銀時の「300円やるから……」がなぜあんなに胸に刺さる金額なのか、今ならわかる。
こんなふざけた商品が1枚100円……？
舐めるな……
起きなきゃいけなくても意地でも寝てやる……
ありがとう。
