    The irony of this coming up in my feed again on the same day as I was in an 18-people meeting 😂 Does Twitter know something?

    This thread is mindblowing in all the wrong ways.

    Opening that grants access to two potential points of entry: a PCMCIA slot, and a telephone modem. Let’s talk about PCMCIA first, because it’s worse. PCMCIA is designed to connect high speed devices to a computer, and as a result it has what’s called DMA: “Direct Memory Access.”

    Strong Concorde flashbacks.

    We agree with Italian PM . Supersonic flight will be a major boost to already-strong US-Italian relations. When JFK-MXP is 3h58 and IAD-FCO is 4h15, people will go more often. Faster travel means more trade and more face-to-face dialog.

    This sounds so exciting that I would really want to play with it... but having to use Java for building anything on top of it is quite a strong counter-argument.

    And you can apparently even build static executable from any of these langs which will actually compile them ahead of time and include only necessary runtime components in the output.
