Oh, wow. Nothing in here that obviously wouldn’t work on iOS.

And this is why professionals didn’t depend on build-time fetch of dependencies.

It’s in SICP, leading up to the adventure game project. That dominated intro-PL conversations for a long time. Also, it’s OO with delegation-based inheritance, prototypes—and some discussion of why.

There is a premium version available. It costs only $30. As you can see at https://aeropressinc.com/use-it-now/evolution-of-aeropress/ , they’ve continued to re-evaluate materials, including testing for contamina

Wellll.... paying Cf customers will get lower latency service using this, just as Cloudfront gives better service to AWS users. That’s part of why this app is in CF’s interests.

Because it obscures the source address for DNS queries, it will mess with split-horizon DNS and other systems that give different answers in different places. You might be surprised how many that is.

More comparable to a raspberry pi. There are some UHF transceivers the size of thumb drives, and a couple beacon designs the size of lithium coin cells—the idea is you clip the coin cell on, then put this in your drone/rocket/bal

That’s a great write up. Another important change is that renegotiation to add client cents is no longer supported. Old HTTPS could work like this: C->S: handshake, no client cert C->S: GET / C<-S: here you go C-&g

I expect jupyter notebooks to keep an environment consistent between cells. Org-Babel doesn’t generally do this. A Good notebook environment is more like a lisp buffer with block comments.

Well, in part because the maximum usable frequency of the ionosphere tops out around 30-60 MHz?

Sure! To talk to a satellite you need an antenna, a receiver, a transmitter, and maybe a computer—not for voice, but for text modes. Arrow will sell you a great antenna: http://www.arrowantennas.com/arrowii/146-437.htm

There are more hams in the US, and more active hams, than ever before. That's a funny sort of dying! Joe Taylor's work on below-the-noise signal extraction has revitalized shortwave: https://physics.princeton.edu/

Well, not the NSA, no—but the same skills that help with Morse are still helpful for radio listening. The prohibition on scrambled meaning long pre-dates WW2, and goes back to old analogies about fencing a commons.

This seems well-intentioned but incredibly dangerous. There's no promise CF can make that justifies trusting them to receive a stream of every request from every FF browser, with all this trackable metadata. In particular, I think it

I had John Fread write in last year. His whole family had learned to be careful picking usernames, and more careful as WAFs and such grew popular.

I don't think the Commons Clause is going to go anywhere: it's not DFSG-free, so Debian and core Ubuntu won't distribute it.

What do the BSDs use to organize out-of-order segments?

I've had an admissions officer at MIT scream at me--handing out leaflets at a protest--that MIT "doesn't admit people like me any more." I think he meant to communicate that they were aiming at more complacent people wh

Go for whatever's cheap and replace it regularly. There's nothing that can be made in small quantities, run off a lithium battery for hundreds of charge cycles, and be durable in a backpack, at that price point.

Produced using processes that we've tested for centuries. We're not sure they work, but we're sure they're not ridiculously dangerous. Contrast glyphosate.

E coli don't rinse off; they form a biofilm with significant adhesion. You have to cook them to kill them.

Yup. Relatedly, devices on a CAN bus don't authenticate each other, and we're seeing real security & safety problems as a result. Ford—or Tesla and Volvo—will start locking those down this decade, or start seeing more incide

I don’t understand. The only way to get Windows programs with a GUI on Linux is through a WINE-style reimplementation of Windows libraries, because it was designed to run all linked together on a single machine. Seems like... software is st

I lived in a dormitory built that way, with double-pipe steam heat. We'd nearly all turn off our heaters in the winter; the ex-californians kept the building so warm that the rest of us opened windows to get down to a bearable tempera

I have neighbors who live this way near Boston, where it's often well below freezing. They wear a lot of wool. Bed curtains and sleeping hats come out in winter. It can be a perfectly pleasant way to live. The lack of dollar signs o

Yeah. Speed is the dominant cost in software, but other industries treat other costs similarly. To pick another darling, look at Tesla: the Roadster is expensive, flammable, suitable only for enthusiasts. The S is generally useful, but too

You know, you can keep the same computer and get even more of a performance improvement by replacing the CPU (and motherboard, of course).

Canonical forms seem a big win. And teeny parsers.

Could you expand on net energy gain?

by brians 9y ago
Yes, absolutely. The trick is to use a very directional antenna—it listens to what you point it at and blocks out noise from the sides. The canonical tool for this is a handheld Yagi, either home made for a few dollars in tubing and screws
