Yeah, sure...from § 11.13.2 of TFM[1]: > In OpenVMS Version 7.1, the DCL PIPE command was introduced. Ask me how I really know OpenVMS v6 doesn't have pipes. [1] http://h30266.www3.hpe.com/odl/axpos/ops

Pipes wasn't a thing until v7.something or other. A bunch of lexical functions weren't implemented until then too.

> However, let's go back more than 35+ years, to a simpler time. To the 1960s. To the dawn of the TTL era. Texas Instruments made a device called the 7473. It was a J-K Flip Flop. But it responded to a pulse, not an edge. Look at t

In uni, I learned digital logic from Brown and Vranesic[1] who explicitly differentiate gated latches from flip-flops, the latter being defined as: > A flip-flop is a storage element based on the gated latch principle, which can have i

Almost. It's a gated D latch, which is level sensitive and behaves asynchronously, as opposed to a D flip flop, which is an edge sensitive primitive.

Ahh, so that's the scalable magic trick they're playing. Thanks for the insight!

I'll be the first to admit that I hastily presumed you were conflating the control theory PID acronym with "process ID", then I looked at the code and had a genuine WT-actual-glorious-F moment.

It's worth noting that this will require registration for a ASTM user account (if you don't already have one) to access their digital reading room. From there, you can either suffer digesting via watermarked-to-death PDF iframe, o

As a more practical usecase, how many other EEs have leveraged circles-in-a-circle packing tables such as [1] to approximate cable diameter and/or size conduit? Would be interesting to learn how other disciplines have applied such a to

Ummm, no...that is, unless your intent is to blindly explore the catastrophic failure modes associated with dielectric breakdown.

That's not an application you can generalize. Literally everything is dependent on requirements.

Just because it looks bare doesn't mean it's unfinished. If I specified sheet aluminum for Type II Class 3 chemical conversion per MIL-DTL-5541, any materials QC professional would be hard pressed to visually determine that anyth

Two questions that come to mind that the blog doesn't address: 1. Is the change in this new revision easily identifiable via PCB silkscreen from its deprecated variant, or will consumers be 0402 resistor hunting? 2. Are (US) authorized

Sure if the industrial weighing equipment leveraged is, say, a weigh-in-motion system with an acceptable GVW tolerance of +/-10% as described in NIST HB 44[1]. In any case, this toy detail was intended to snuff out the grandparent&#x27

And how would you propose one gain intuition on what individual pieceparts of a build-to-print submarine ought to weigh, especially given the scale (and relative weight) of the thing in error can't easily be gauged by any individual? 1

It's a meaningless question if the person answering it simply doesn't have some qualitative frame of reference to gain intuition from...and gaining intuition on EM phenomena grounded in reality isn't easy; there'd be a l

Yes. What the slide rule era didn't have was the internet. EDIT: Here's a 1992 GAO acquisition study[1] on the AN/BSY-1 combat system whose development started in 1980 and was an absolute clusterfuck for the Navy in the decad
