I had a school network that was apparently someone who decided that, since BNC T-adapters existed, there was clearly no reason to follow the 'daisychain the machines together' rule, and just spliced in a few branches here and ther

There is also the excellent series of demonstrations and explanations by Dan Gelbart[1] on high-precision techniques, aimed at scientific instrument prototyping. It kinda presupposes a much better equipped workshop than many will have acces

Why isn't volatile sufficient here? If they were both modifying the same variable, I can see how A:read Ax; (Interrupt: B:read Bx; B:write Bx+1; return); A: write Ax+1 # (wrong!) could occur. But the only error I can see here is that

How would you implement that though, assuming memory is tight? The simplest would be to just store a multibyte entry for each item in the ring buffer: the actual data, and the status flags set at the time it was copied. But that doubles you

Are there any good introductory taxonomies or categorisations of threats and potentially appropriate responses? The obvious distinctions that spring to my (uninformed) mind are: active (mitm, injection) vs passive (snooping, traffic analysi

I think they're mostly in geosynch/geostationary at 36,000-42,000km or so, with latencies of 250-350ms (pure travel, not including queuing or processing delays)

years and years ago I had some thoughts tumbling around about how I'd design an automated system for muting/vibrate-mode only for phones in cinemas/libraries/quiet-zones, etc. The security implications and UX involved in

and solves the other problem of Big High internet, which is latency. At 1000km you could have single-hop round-trips in <10ms.

How far did you get? What went wrong? What sort of latency/bandwidth did you expect to achieve? Was it relaying via geosynch/higher orbit 'hubs' or peer to peer sideways routing?

They could add a bypass circuit around their boost converter, which would give virtually 100%[1] efficiency until the booster actually fires up. Something like the TI TPS61291[1] draws only 15nA in bypass operation, and maybe 85% efficient

The cynic in me presumes that it's to make up for the lost cash in charging you individually for all those subdomains. What do you mean about cert errors on a single domain [requiring a wildcard]? Because you use a lot of subdomains, o

Even the actual SSID name is probably more than an ordinary app needs to know. Unless it needs some sort of location data to provide functionality, what is the minimum set of facts that would cover app behaviour? I guess they might want to

For managing large infrastructure, it's possible with semi-recent openSSH (5.4+ I think?) to validate and revoke keys[1] by signing them with a different key which the server (or client) trusts. [1] http://www.lorier.net&#x2

This looks pretty neat -- however, do you use passphrases for your keys, and if so, how do you manage them? Only 2 obvious solutions spring immediately to mind - use the same (or none) pass for each key, or have a unique one per-key and som

Now that's finance-industry thinking! In fact, does the cost even need to be non-negative? Why not demand a 'playee fee' to be added onto your winnings.

In the simplest case, the thing referred to is 'a think', and they're entirely equivalent :) I'd argue that this is more of an Eggcorn[1] than a malapropism, unlike your second example. "The proof is in the pudding&

There are alternatives, such as some of the work done by Masataka Goto in drum-free tempo/beat detection, see [1] for some literature. I haven't kept up with the literature, but his work is quite old now, so I wouldn't be sur

The bad reason is "Because we do, and we're the best. Those researchers are just slackers". One good reason would be to prefer passive sensing, because LIDAR is equivalent to waving a laser across the entire landscape, precis
