@eve_bouff I can see my house (ok well, office) from here!

[Arlen Abraham @ArlenAbraham]

Bruh,
1) If I go to bed at 5:30 I’m gonna wake up at like 2am, 3 if I’m lucky.
2) I still had 2.5 hrs of biking to do.

@WHOOP this hurts your credibility. I’m no doctor, but I’m pretty sure this isn’t how sleep works. I *wish* I could sleep that long.

We (@cascade_space) are hiring a mechanical engineer to help us build the world's first commercial deep space communications array. Know someone who might be interested? Hit me up! https://t.co/lgzGJsYte4

🌕 @gru_space is building durable space habitats so humans can one day live on the Moon and Mars.

Its first missions will mine lunar regolith to construct a long-term pressurized habitat on the Moon for commercial space tourism — a hotel on the Moon.

Congrats on the launch @skyler_chan_!

Dear @AnthemBCBS, I do not want a chatbot, stop trying to ram it down my throat so hard that it covers the "check out" button when ordering things from the pharmacy.

[Cascade Space @cascade_space]

The Deep Space Network is oversubscribed and unavailable for commercial space missions.

Commercial alternatives are limited, fragmented, and unreliable. Even if they worked well, there are not enough.

We are building new, modern infrastructure. Designed to scale.

@LinkedIn Furthermore, LinkedIn has no way to report candidates who are spamming applications using automated tools.

You could literally ask "Are you violating the terms of service?" and the bots would say "You're absolutely right! This is a ToS violation!" then apply anyway.

[Arlen Abraham @ArlenAbraham]

I posted a job to LinkedIn with two basic screener questions:
- Are you a bot?
- Are you a US person? (hard requirement due to our customer base's potential ITAR requirements)

A shocking number of "applicants" failed both screeners and LinkedIn is now trying to upsell me.

[Arlen Abraham @ArlenAbraham]

Now that my applicant queue has filled up with *self-verified* bots, @LinkedIn is trying to shake me down for $100/DAY to get more garbage applicants.

Is LinkedIn even using their own product to hire? To they realize what a tire fire this is?
