Record-breaking chip can transmit entire internet’s traffic per second

Record-breaking chip can transmit entire internet’s traffic per second:

The speed record for data transmission using a single light source and optical chip has been shattered once again. Engineers have transmitted data at a blistering rate of 1.84 petabits per second (Pbit/s), almost twice the global internet traffic per second.

It’s hard to overstate just how fast 1.84 Pbit/s really is. Your home internet is probably getting a few hundred megabits per second, or if you’re really lucky, you might be on a 1-gigabit or even 10-gigabit connection – but 1 petabit is a million gigabits. It’s more than 20 times faster than ESnet6, the upcoming upgrade to the scientific network used by the likes of NASA.

[Cool. (Also, meh. My son’s gaming probably uses more bandwidth than that… 🤷🏼‍♂️ 🎈)]

Elon Musk says he can’t cover Ukraine Starlink costs after diplomat insult – The Washington Post

Elon Musk says he can’t cover Ukraine Starlink costs after diplomat insult – The Washington Post:

While SpaceX at points has portrayed Starlink service in Ukraine as an entirely charitable venture, it has not, in fact, covered the entire cost. The Post reported in April that the U.S. government had quietly paid millions to SpaceX for equipment and transportation costs.

[Not as kind as they would lead you to believe.]

Production Notes: making an iPhone Video in the Field – David Smith, Independent iOS Developer

Production Notes: making an iPhone Video in the Field – David Smith, Independent iOS Developer:

What I have found is that it is essential that the audio be recorded directly into the iPhone. While external recorders can be later synced up in Final Cut, this process is super cumbersome and means that you can’t easily check your footage in the field. It is also essential to have some kind of wind/weather screen on your microphone, otherwise you will constantly be ending up with unusable shots where all you hear is wind noise.

[On it. Kinda. Sorta.]

Run multiple Rails apps with Puma-dev

Run multiple Rails apps with Puma-dev:

Puma-dev presents a better way
By running a background process to manage all the Rails apps, starting them, and shutting them down when idle, we can avoid the tedium of managing multiple Rails servers in multiple terminal windows. We also get:
HTTPS support
.test TLD

So instead of http://localhost:3000 and http://localhost:3001 we get https://web.test and https://auth.test (or whatever name we like).

Here’s how you can use it.

[Sure enough…]
