3D printing stuff that's foodsafe is nontrivial. You not only need a material that is not directly harmful (in temperatures it will be used in), but also most 3d printed surfaces will not be smooth. This makes them very hard to properl

Fair point. He says that the 20% estimate is unlikely to be revised upward, but it's "unlikely because you can't get more than 30% using reasonable approaches to PV" and not "unlikely because you can't get more

Note that some of the statements there (e.g. estimates of areas needed to provide power from solar energy) are not technology-dependent (ie. are about physical limitations).

Ah, I see where the disagreement lies. I've thought that by downsides you mean _relative_ downsides, whereas you meant absolute ones. Thanks for the detailed explanation of your position.

I do not have an opinion on whether CoreOS is geared towards large deployments. However, I very strongly disagree with the example you give. Every person who does Ops work has an SSH key. Creating one and keeping it on your laptop/desk

Don't do this on your domain. Have a separate domain for user content (and, if the content isn't public, better have many separate domains and distribute the content between them; maybe even have a per-user domain). Browsers can b

I find it weird that all the standards in the privacy space (that I know about) seem to me to be much more about checkbox-checking compliance (ie. following their letter doesn't help much or at all) as opposed to standards in reliabili

My family has a furnace for heating water and the house. The furnace has a control unit that controls the burner and pumps. There is also a "manual operation" switch, to be used if the control unit fails, that simply switches ever

Why do you create an env variable that contains the whole file in question when the editor returned success? Wouldn't something like: cat "$f"; rm "$f" not involve loading the whole file in memory at once? No

There are other methods to prevent such occurrences: furnaces have "flame out of bounds" sensors and/or chimney flow sensors: this is very good at preventing the furnace from starting a fire of its own. If there's alread

I find such a comment to contribute more to the discussion (if it's actually discussed) than all the anecdotes from many of the other top-level comments. They are nicely worded and afford many points that can be discussed, most of them

What kind of incident could safety regulations be trying to prevent by forbidding a furnace from operating when remote control is unreachable?

Is this really the semantics "backup plan" has for many people? For me it's something that's very inferior to the, well, plan.

Also, this is one of the cases where you can probably free up some memory bandwidth by transferring compressed samples around.

The interface is slightly weird. If I call Sub() twice (e.g. in two different goroutines) for the same queue, each message will be received by one of these two subscribers (because the channel is shared). I'd expect exact opposite: all

Note that this is a very indirect way of harming someone: eating peppers has (likely) caused vomiting, violent vomiting has caused rupture of the esophagus. This is similar to saying that walking can cause fat embolism (a life threatening c

The way I read your argument, it relies on denying access to be cheaper or simpler than spoofing (X == spoofing, Y == denying access to authoritative NS): You are arguing that a kind of attacks is made more dangerous, because in the world w

Right now, to keep a poisoned entry one must keep poisoning the cache. In that world, one can still do that. One can also poison the entry once and then deny access to the real server . You seem to be arguing that this is easier than conti

All the attacks mentioned here seem to be of the following shape: 1. Let's somehow get a record that points at a host controlled by us into many resolvers (by compromising a host or by actually inserting a record). 2. Let's prolon

Attacker's first attempt has a nonnegligible chance of success. Attacker can just do one attempt against one account and move to attacking a different account after each failure.
