Diederich··on Boeing Starliner launches first crewed mission
Yeah this morning I was thinking about what the astronauts must be thinking.

I would ride the Atlas/Centaur stack, it's been exceedingly reliable. Starliner itself? Not quite yet, given its checkered history.

Boeing brings up nothing but sadness in me these days. I really, really, really want that company to succeed and be awesome. Hopefully going forward Starliner will bring forward the excellence that has been Boeing in the past.

Diederich··on Starlink as a means to win at nuclear war
This is obvious but I don't see it discussed or mentioned that often, so far.

Massively decreasing the per mass cost of delivering any kind of cargo has huge and complex implications.

Massively decreasing the per mass cost of delivering cargo across oceans was a big deal.

Massively decreasing the per mass cost of delivering cargo across continents by rail/road was a big deal.

Massively decreasing the per mass cost of delivering cargo by air was a big deal.

"Big deal" here means all kinds of things, but let's talk about war.

Every one of the above mentioned steps caused radical changes in how wars were fought.

What have we seen over the past few years, even prior to 2022, in terms of drones? Massively decreasing the cost of precisely delivering small explosives over short ranges, with drones in this case, has been a game changer.

Even without a fully functional and reusable Starship system, SpaceX has greatly decreased the cost, cadence and reliability of delivering cargo into space. I understand the price they charge for individual launches is only 'somewhat' below the competition. That incremental but rather sudden decrease has already opened up a lot of doors.

A fully reusable Starship system drops that cost by at least another order of magnitude.

We are on the cusp of another revolution in warfare, and it's happening far, far more quickly than any of the other previous revolutions.

Imagine hundreds of thousands of smart kinetic munitions in many LEO orbital inclinations. According to https://en.wikipedia.org/wiki/Kinetic_bombardment a 20kg tungsten kinetic munition in LEO would deliver about 11 tons of TNT to the ground. Each SpaceX fully reusable launch to LEO could deliver about 2,000 of these. I didn't look it up, but I believe SpaceX has done about 150 Starlink launches so far. If each of these had delivered 2,000 kinetic munitions, there would already be 300,000 up there.

As far as I know, there's absolutely no defense against this kind of munition. In LEO they're moving at about 8km/s, and just before sea level impact they're moving around 3.5km/s. At best there could be a few minutes of warning.

Any entity that controls such a constellation would have what is effectively absolute and permanent air supremacy while risking no 'friendly' human life.

As far as command/control/tracking/sensing? Very low $/kg to LEO fixes that too. See Starlink and Star Shield, right now.

Nobody can predict how this will go, except that it will definitely 'go' in unexpected directions.

Diederich··on Boeing Starliner's first crewed mission scrubbed
From what was said at the scrub conference, with additional context, it was scrubbed only because of more strict rules regarding it being a manned mission. Normally they would have just recycled a valve and moved ahead with the launch. Apparently the rick here is extremely minimal.

Can you expand on that? Thank you.

Diederich··on Systemd replacing ELF dependencies with dlopen
Well fair enough, I remember that with great excitement back in the day. Is it possible that MSFT has moved on from this perspective?
Diederich··on Ask HN: I want to create IMDB for open source projects
Here's an example of what it looked like 21 years ago: https://web.archive.org/web/20030204090614/http://freshmeat....

Back then, for years before and after, I looked at it almost every day. It was my go-to 'take a quick break from work while at work' site.

Diederich··on Systemd replacing ELF dependencies with dlopen
> glaring conflict of interest

Can you expand on that?

Diederich··on School absences have ‘exploded’ almost everywhere
I've never had COVID. In fact, the last respiratory infection I had was in 2019. I sing, masked, in a 90 member choir where few people do mask, and we've had a couple COVID outbreaks. In one case, the people who sat to my right and left both caught the bug.

I'm not going to speak to the particulars of the various mask mandates. That's a complicated and nuanced question. One thing I know for sure: N95 masks, properly applied, make a huge difference to (at least) the person wearing them.

> And, it lost power at almost exactly the worst moment. What are the odds?

I don't know, but I suspect we don't hear much about all the times power is lost at moments that are less than the worst.

Diederich··on A simple MUD server in Python which can be run on a Raspberry Pi
I still play https://mume.org/ from time to time. It's been running (almost) continuously since 1991. I started it in 1992.

Diederich··on C and C++ Hot-Reload/Live Coding
Back in the early 90s when I was writing https://en.wikipedia.org/wiki/Multi-user_dungeon 's, and for a while had quite a few players, I was always keen to move as much functionality as possible into unloadable/loadable libraries, since restarting the game was quite invasive.

To my surprise, this was seen as a pretty amazing feature at the time. I never understood why many/most of the other MUDs at the time didn't utilize this.

Diederich··on 23andMe updates their TOS to force binding arbitration
Hah, beautiful, well done.

But yours isn't nearly so...catchy looking...as the New Yorker version.

Diederich··on Starship will attempt a launch this Friday
Right, I believe they will be a few tens of meters per second short of orbital velocity.

> They will be finding problems in this thing until the day it's taken out of service.

Is this similar to how they developed the Falcon 9 platform?

Diederich··on Google was founded 25 years ago today
Well I got one of my domains almost 28 years ago and I still haven't done much useful with it. (:

    dana@eighteendotfour:~$ whois realms.org|grep ^Cre
    Creation Date: 1995-10-17T04:00:00Z
    dana@eighteendotfour:~$
Diederich··on Google was founded 25 years ago today
So they registered the domain close to a year before incorporation:

    dana@thalos:~$ whois google.com|grep ^Creat
    Creation Date: 1997-09-15T07:00:00+0000
    dana@thalos:~$
That seems fast to me.

That's interesting. If you have a moment could you expand on that? Thanks.

Typo there :)

Diederich··on Why Perl?
I'm not going to necessarily disagree with you. Perl was my professional go-to language for about 20 years, and I moved on to Python for the past eight or so.

Back 15+ years ago, you'd see perhaps 2-3x more updates on CPAN recents per day than what's there today.

I'll always love Perl, but it's definitely on a long slow popular decline.

Diederich··on Why Perl?
> Yeah, because the ecosystem is dead.

Is it?
