Neat pic (after I figured out I had to zoom in to see the destinations). It's just missing the route from the Moon to Earth Intercept(/Escape). I'd also love to see these maps include routes to the asteroid belt from the Eart

Interesting, I didn't realize Earth's gravity was still so strong at 500km up. Getting payloads to the station from space would still be cheaper because we could rely on aerobraking, but accelerating mass to Earth escape velocity

HPC systems also tend do an unusual amount of stuff in userspace, such as running custom TCP stacks in userspace or using RDMA to bypass the CPU entirely. You wouldn't want to run a 10GB+ multiqueue Ethernet NIC on a single core, it&#x

My point is that just getting projects started in space has a high barrier of entry due to the expense of moving personnel and structures into space. If we had permanent residents there, and the ability to manufacture the structures in spac

Wow, I had no idea the Shuttle was so crazy high. Wikipedia says it ranged from $16.5k - $50k, not sure on what basis. I guess the drastic cut in launch rate must have really tanked the efficiency of the program.

I think the lag in certification partly came from NASA's risk assessment of some of SpaceX's plans. NASA increased focus on the risk of micormeteorite damage to the Dragon capsule while it is docked to the ISS, which has required

I pulled the Saturn V and Falcon numbers from Wikipedia, which were in 2016 dollars.

I'm not sure what the delta-V is like to get materials from an asteroid vs the Moon, but I'd expect there is much more variety of resources on asteroids. I think an orbital station is also more attractive than the Moon from a delt

I really want to see asteroid mining prioritized, as well as a space station capable of permanent human habitation (either partial or full gravity). A space station is also preferable to another planet for our next big space endeavor IMO be

It's recently gotten way cheaper. Cost per kilogram delivered to LEO: Saturn V (used for the Moon landing mission): $8,250 Falcon 9: $2,700 (price for an expendable launch) BFR (hypothetical, in development rocket): $500

The weather effect isn't about the cost of the shelter space. There is less incentive to put up with shelter rules (or risks, as the case may be) when the homeless can sleep outdoors somewhat comfortably year-round.

The conclusion that Facebook has bots other than Facebot is interesting. I wonder if Scott was able to identify how many problematic user agent strings were on Facebook's network.

See my reply to mmebane about sub-commits. Re: UX, specifically the patch editor (git add/reset -p) is sometimes difficult to use. For example, I've had issues with changes that happen around empty lines refusing to apply for unkn

Interesting! That's almost what I want, except here's the specific behavior I want to achieve: A clean git log view that shows only meta-commits Git blame shows both the meta-commit and the sub-commit for each line I supp

you can --keep-index to avoid stashing it, and then make an additional stash. If you have modifications within the same file it'll complain about conflicts though, so on the second sash you'll have to `git stash show -p | git appl

Some useful commands I'd use in scenarios like this are: git add -p # select what to add to the staging area git reset -p # deselect chunks that I decided I don't want anymore git stash # saves your working state in a temp

It potentially reduces the ability for new web companies to succeed in reaching US consumers. It will also enable ISP's to extort existing web companies and lead to higher prices for consumers.

Small orders are much more expensive to deal with. Higher shipping and handling costs, extra customer support load, etc. Why bother selling a few hundred or thousand devices with all that overhead when you can focus on selling large volume

No, UEFI actually leaves components running after the OS boots. This talk discusses how to replace the proprietary UEFI BootManager with a Linux kernel, and then uses it kexec the Linux kernel from the boot device.

Performance and reliability definitely affect subscription rates. Revenue growth is actually more important than decreasing costs (as long as your costs don't start increasing disproportionately).

The wording got mixed up a bit. "Infrastructure" was a much larger organization, but there was an infrastructure team of about 12 people who worked on Magic Pocket at the time. https://blogs.dropbox.com/tech/2

Oh wow! I was trying to write this myself last week, and got about halfway done before I realized that my credit card rewards booking system gave me different prices than Google :( Major kudos on implementing the AirBNB search as well!

There's different sizes of TODO. For anything beyond small cleanups, yeah, an issue is probably warranted. But, filing tasks in the issue tracker aren't always the best solution either. They often become out of sync with the state

Seccomp, apparmor, and namespacing (especially user!) do add a lot more security than plain old chroots, but still not at the level of a VM.

OpenVZ was an early container implementation that required patches to the Linux kernel that never made it into mainline. Parallels acquired the company behind OpenVZ, Virtuozzo, and then worked to mainline much of the functionality into wha
