It's all about jokes, funny pics...

A man walks into a bar, dejected another veritable disaster of a relationship attempt.

One, bourbon, one scotch one beer please he requests from the bar person.

Sits on a stool at the bar glances at the small dish of nuts....... one of the nuts jumps out of the dish.... hey fella like your hat, you sure look good.....

He shakes his head, this cannot be, he must be in a much worse state than he imagined...

Another nut jumps out of the dish. - hey fella you look much younger than you actually are..... jumps back in...

What the, how the heck could the nut know how old he was....

Bar person arrives with the order, puts the drinks on the bar.

About these nuts on the bar...

Bar person cuts in No charge for the nuts they are complimentary
 
Anybody already mentioned the i_DONT_CARE_IF_MY_BUILDS_TARGET_THE_WRONG_RELEASE=yes shell variable that is required if you're trying to source-upgrade from 12.? to 13.? in a chroot directory on a 12.? kernel? That was a nice 1, actually...

A guy posts in a technical forums:

"Those nitpicking peas-counters really can be annoying.
You simply want to make a point just for discussing a topic frisky.
But if you keep it short, they correct every single word of yours. Telling you, it's completely wrong to put things that simplified.
So you try to express your point elaborated. View at things nuanced, make distinctions. Try to be understanding. Respect every aspect. Display you engaged to the topic, no need to weigh up and discuss every single word - just make your point.
Trying hard for not to be misunderstood. Just trying to put another perspective into the discussion whithout pissing someone off...
Then they not only complain you write way too long posts. They also miss the point you trying to make, completely.
And they still nitpick on some minor pettiness!"

First post he gets:

"This could have been put more briefly.
And it's bean-counters, not peas-counters."
 
Heat sink design is an art.

I scanned the picture (without asking for permission :sssh:) from
Robert A. Pease, 'Troubleshooting Analog Circuits', NS/Newnes/EDN, Paperback reprint 1993
showing Bob Pease experimenting with a semiconductor for high power usage using a heat sink from the aircooled engine of a VW Beetle (he was driving such until his death in 2011 - 'There is no need to change while it does its job.')

You may always use a passive heatsink only without a fan.
But you have to provide enough mass of good heat conducting material (copper is very good) to get small heat flow resistance for the heat flows fast enough out of your part (IC 'chip', CPU), and above all enough surface to bring the heat out of the heatsink into the cooling fluid (air, or water).

Heat sinks are one of the most expensive parts you can have on electronics, being lots of expensive material (mostly aluminium, sometimes copper), costly in production.
Plus you get additional needs such as the space needed for it, and its weight.
I would roughly estimate a passive only heat sink working even with warm room temperatures like in summer time (~40°C) for a modern x64 multicore CPU as we use in our desktop PCs today would need the size of a small wardrobe. ?

Also the surface coating is important. If Apple used the housing of its III to be the heat sink's surface exposed to air it had been worth a shot to test using another varnish of the housing (e.g. radiator paint), while I bet they just decided to 'paint it commonly.' Most paints insulate heat.

The fan simplifies it a lot.
You may use a (way) smaller heat sink at way lower costs, smaller space, and get enough reserve.
With a passive heat sink you have to calculate more accurate (it's a tricky job) not to get a way too much oversized monster (like Bob could afford for experimenting), or to get it insufficient as with the Apple III.
(Which again is prove to me Jobs was not the technical engineering brain of Apple [he provided his garage, and his VW Bus] ?)

Lets be honest, the early driver support for BSD will be lacking and yet we will install FreeBSD on it anyway.

The poor robot will end up half-lobotimized, paralyzed and yet still probably overheating due to primitive power management and thus subsequently squashed in the cupboard filled with Raspberry Pis in the vague hope that open-source driver support improves in the next decade or so.

The machine might have a different form factor, but it will be the same old shite that comes with "modern" hardware.

In other words, my wife has nothing to fear XD

Bob Pease was a genius, not only at designing analog circuits, but also explaining them to the masses, in particular through his column in the magazines.

And he was driving the beetle when he died. Never met him in person, but he must have been a great guy.
 
It was a real tragedy. He came from the funeral of his friend Jim Williams when is VW Beetle came off the road and crashed.
The world lost two of their top electronics engineers in short time.

He was.

He always tried to answer all e-mails containing questions about electronic circuits - he loved knotty electronics problems.

I once asked him per e-mail about a tricky OpAmp circuit I was trying to design and which had puzzled me for a couple of weeks.
I got a circuit sketch personally by him. ?

I have copies of most of his national.com website I could get, above all the "Bob Pease Show" (when internet video-stream was a brandnew thing [don't expect 'HD'?])
I expected they will shut it down sooner or later (that was before youtube, and before National was bought by TI.) I didn't checked it for a while, but I think the site is down.
Oh,...I just figured out:
It's all on youtube: The Bop Pease Show - what an effort I had to download those... :cool:
Cool, there is also the video of Bop throwing a computer off the roof top
He hated Spice - since those days spice wasn't really usable for analog stuff, but actually only for what it originally was designed for: TTL

I hope his family and his 'co-pilot' Paul Rako is well.
 
Someone needs an appointment with more training, or maybe a clue bat. What is this supposed to be?

I'll convert it to a knitting pattern, patent the conversion, make money from licenced copies of the pattern and become wealthier than Percy Shaw.

Thanks sko, and apologies in advance if I don't extend the licence to EU countries. I can't be bothered with post-Brexit red tape.

I’ll buy that a lot faster than any Musk robots. As a lifelong feminist and a widower for 23 years, my main amusement/bewilderment here was the mere existence of, and indeed, prevalence of “anti-feminism“ in modern culture, and to ridicule Elon Musk, whose foray into robotics seems as dull, ponderous, and clumsy as his other ventures.
