Thanks very much for that. In terms of comparing the two approaches, I can see that if you are granting different creds based on a user auth, an STS is useful to grant temporary creds limited to a subset. I'll need to look up the detai

So - there has to be some trust to the client, unless the resource is public (or locked down with end-user creds). In this case, some kind of creds need to go into the app, right? So the best practise is simply to make those some creds whic

Would it work to have a different response to collision, namely to apply a reverse of your last step? (A full reverse or partial). There might still be corner cases, but it would seem to resolve the described issue, since irrespective of wh

There's presumably no more energy being dispersed than with manual brakes. The current brakes will heat less (due to energy in the ERS). If the ERS is full, you either switch over to dumping the heat into the brakes (no ERS, switching

Still not sure how that helps. In both cases, we have creds embedded in the app which can be used (and only used) for access to the AWS resource. In one case directly (via an IAM limited account), in another via a token they can request. In

I'm being dumb. I can see that it is preferable to embed credentials for a restricted IAM acct, not your root/master AWS account. But how does using a TVM improve the situation? Surely you still need to embed creds which allow the

I think the main difference is the way the language and runtime collaborate to schedule multiple events. Note the use of the 'select...case' in the example code. These slides go into some more examples: http://talks.gol

I wasn't quite getting that code when I first read it. Now I can see it allows you do "discard" all the pending reads from the input channel (and avoid writing to a possibly-closed 'out' channel), but wouldn't

I'm not arguing the point that generics are unuseful. But imho the method should not be named for the compiler-type of it's return value (unless it's a type converter like int2string or similar). It should be named for the

Design is different to the nitty gritty but I'd say not necessarily easier or harder. Just as no battle plan survives engagement, no design survives the realities of implementation. This is what makes waterfall hard and agile.attractiv

Move up the value chain. If you can turn a design into code, learn to turn a spec into a design. If you can turn a spec into a design, learn how to understand a problem and produce a spec to solve it. If you can understand a problem, learn

PRNGs (pseudo-random-number-generators) take in a small amount of randonmness (a seed) and produce a long stream of numbers from that. Anyone using the same PRNG can look at the output of yours and try to put their PRNG in the same state. I

I like to use a syntax error if I'm implemented in the middle of a number of related changes. As long as I follow basic hygiene of running/compiling the code before committing, I'll be reminded of where I was. I typically use

Duodecimal counting still persists in some places in inches-per-foot and in the UK until 1971 in the "pounds, shillings and pence" old-money system. (12 pence to a shilling and 20 shillings to a pound). It's interesting to me

I think the thing which is defeating my intuition here is the continuity issue. "If a periodic function is continuous and nonconstant, then it has a least period, and all other periods are positive integer multiples of the least period
