I\'ve got a 5500U in my laptop. It\'s a 7nm Zen2 unlike the 5600U Zen3

I have no complaints for a $700 laptop.

That\'s 0.4 of the speed of my desktop. Laptops suck.

Until the company upgraded my desktop I was using the laptop for some
projects. It beat the hell out of an elderly Core i5 with a hard drive.

I\'m not a real fan of laptops but they have their place. I\'m using a
company supplied laptop for remote work. Admittedly the HDMI is plugged
into my desktop monitor though a switch and I use a bluetooth mouse and
keyboard but it\'s good enough to VPN in to a real machine.

It\'s also difficult to travel with a desktop...

I wonder what would happen if you tried to set up a desktop, keyboard,
mouse, monitor on a table on a train?

First you would have to find a train...

You don\'t have trains? They\'re annoying things with shitty brakes that
would cause a car to be taken off the road. They expect everything else
to get out of their way. And they never go where you want to when you
want to. About time we got rid of those useless things which actually
use more fuel per person than a car.

Oh, we have trains but they\'re hauling coal to BC to ship to China.

https://www.youtube.com/watch?v=8OmTnWxpcEQ

No passengers, no tables. We have two passenger terminals but they\'ve
been recycled to other uses.

https://aws.boone-crockett.org/s3fs-public/thumbnails/image/hq-bcheadquarters2015.jpg

That was the Milwaukee Road terminal but they went under in the \'70s.
You can\'t see it but in the foreground the rails have been ripped up and
turned into a bike/pedestrian trail. The other terminal is next to an
active rail line but the coal trains don\'t stop.

The closest passenger terminal is 133 miles north. You might want to
think twice about setting up a computer on the Empire Builder:

https://en.wikipedia.org/wiki/2021_Montana_train_derailment

Except for the east coast routes favored by government drones like Biden
US passenger rail is pretty dismal. Freight isn\'t much better:

https://www.freightwaves.com/news/fertilizer-maker-faults-union-pacifics-plan-to-reduce-congestion

The second one is the money shot. A major fertilizer manufacturer can\'t
ship its product to the Midwest where the farmers are getting ready to
plant. If the farmers skimp on fertilizer the yields will be down. Just
what we need with Ukraine off the table at least for this season.

Not without giving up un backward compatibility and making a clean
break. Which has been against Intel theology for a long time.

Apple went through the same thing, and eventually hired a bunch of
market research firms to run focus groups sessions...
The question to be answered was if there had to
be a Motorola processor on the motherboard, or would a really good
emulator suffice. The vast majority of those in the focus (myself
included) said that no Motorola hardware was needed, so long as the
emulation was in fact that good, because we all had essential software
that could not be replaced for one reason or another. I assume that
most of the focus groups came to the same answer, because that\'s
exactly what happened.

Joe Gwinn

It was a stretch, though; there was a \'toolbox\' runtime library, and the
rewrite of that was probably the first need, because it would normally
be cached, and a two-stage emulator-plus-toolbox requirement used
a LOT of cache. Apple had some PowerPC processors made with extra-large
cache in the early days of the 68k-to-Power changeover, and eventually
the OS\'es became incompatible as emulations were dropped, first 68k
and then Power code in the Intel years.

Yes, but never mind the details, Apple did get it to work very well,
and maintained it for about ten years, then ceased to support it. By
then, most of those critical apps wee no longer critical, or had been
killed off by something else.

Nobody does anything critical with a Mac anyway. They\'re just for arty folk.

Well I\'ve never been accused of being arty, but OK.

But for really critical stuff, nobody uses Windows for sure. It\'s
Linux all the way, often controlling bespoke FPGA hardware.

Why no Windows? Well, the US Navy tried, in the SmartShip IT-21
program, for which the USS Yorktown was the testbed.

..<https://en.wikipedia.org/wiki/USS_Yorktown_(CG-48)>

Long story short, someone in the engine room entered a bad value of an
input form for pump performance recording, and crashed the Windows
computer system and all associated shipwide networks. The ship was
dead in the water, without propulsion, steering, or weapons. What
could go wrong?

Fortunately they were far from land, and not in a battle, so they
didn\'t get sunk or blunder into anything. They had to reboot the
entire ship. This all took about three hours.

That was the end of SmartShip - only the name survived, used only for
administrative activities, isolated from all tactical networks.

UNIX was the follow-on answer, but the various big platform vendors
became too expensive and too inflexible, and over time everything
migrated to Linux, mostly Red Hat Enterprise Linux (RHEL), which IBM
subsequently acquired. Wonder if IBM has learned anything since DoD
abandoned AIX.

Not an uncommon view, but inaccurate. Excel, for example, started life
as macintosh-only code; the Windows version was an afterthought, ported
over.

Isn\'t Excel just a Windows steal of Viscalc? Lotus 1-2-3 came next, so Excel is more a Chinese copy of that that exploited the Widows graphical user interface - and of course the MacIntosh had the first commercial graphical user interface, copied from the Xerox PARC Alto machines (of which there were a couple of thousand, although it was never marketed).

Visicalc was the killer application for the original Apple 2 computer. Dan Flystra made a lot of money out of it - I had an acquaintance at MIT at the time, who had run into Flystra who was also active in starting up Byte (which was how I got to be foundation subscriber to the magazine).

Ok, in 2040, where will you buy gasoline, at the airport? The remaining ICE on the road won\'t justify keeping open a distribution network for autos. While gas will drop to probably $2 a gal in the next couple of years as BEVs start to make a dent in the number of gas cars on the roads, that will only last so long before prices start going back up as it becomes more costly to maintain the distribution network for the smaller amount of gas being produced. As the demand drops, eventually it will be very expensive, like $10 a gallon, to get any gas at all, and it will all be unleaded regular. So don\'t plan on running your high performance, high compression muscle car..

The idea of running an ICE for another 45 years is pretty much a fantasy at this point.

You may be right. Could be three years.

Do you have a BEV? The only people I\'ve seen complain about charging times, are people who don\'t own them.

Personally, I don\'t see a need for faster charging. My car is a bit shy on range from what I\'d like to have, but then it is nearly four years old and they do much better today.

Don\'t buy that either. And even if it was true, much more of a nuisance
having to do it most days instead of once a week or so.

Do what most days? Plug it in when you get home. Set the timer to charge at night when electricity is cheapest and you never have to visit a smelly gas station again.

New models have a range comparable to a gas car, 350 to 400 miles.
Yeah, takes 30 seconds to plug in twice a week. Still faster than
stopping at a gas station.

Rather than dwell on the negatives, educate yourself and you will find
many have been overcome or will be soon.

Many simply don\'t want to learn about BEVs. They want to believe what they want to believe. That\'s ok. Anyone will be able to keep their current car as long as they want. They just won\'t be able to drive it because no one will continue selling gasoline when only 1% of the country want it.


If I had need for two cars, one would be an EV today. Even now, it is
good for 90% of my needs.

I haven\'t found a use case my BEV doesn\'t fit. It does a lot of things my old car didn\'t. Oh, wait, there\'s one thing I can\'t do in my BEV. I can\'t rev the engine in neutral or make a bunch of noise. Oh, I can\'t blow smoke out of the exhaust and I can\'t murder anyone by piping the exhaust into their bedroom window. Yeah, and I can\'t use the fuel to start a fire. Geez, there are so many gasoline fires in cars. Those things are DANGEROUS!

Cars today no longer have to be hand cranked to start and the top models

Ya, I\'ve had enough meters apart that after it was said, I remembered
the counterweight on the opposite end of the pointer.

It helps with clock hands as well. I have a cheap wall clock that would die when the battery didn\'t have enough power to move the second hand uphill. I added a counterweight and it runs a couple of months more now before I need to replace the battery.

That used to be a standard feature on clock hands when they were wind up. A lot of electric clocks don\'t bother. Also they often don\'t have second hands. The leverage on the minute and hour hands is a lot greater.

Nothing much has changed in any of those fields - they are pretty mature
tech.

Coincidentally, I had a conversation this morning with an engineer who
works for Ford. He works in image processing; one of the projects
he worked on a few years ago enables the backup camera to initiate
braking if it sees an obstacle. He actually benefited from this
feature on a cloudy, gray day when he was backing up toward a gray car.

My husband gave him an idea for additional features for automatic
headlights. He said he\'d split his bonus with us if he gets one.

There really is a lot more going on than you realize, TNP.

I think TNP has reached his “new tech” limit.

The automatic headlights on my car are quite amazing. I haven’t worked out
how the work but they’re a *lot* more sophisticated that a simple forward
pointing photocell. I suspect some fairly serious image processing is going
on.

I assume you mean the high beam control? I don\'t use it. It\'s pretty good dipping to low beam, but it seems like a lot of things prevent going back to high beam. I just work that myself.

Yeah, they keep saying that about computers, too. And they\'re
constantly proved wrong.

They are completely right about computers. They cant be clocked any
faster, they cant be made to work with much less power - all they can do
is add more cores.


The new(ish) Apple processors use a fraction (between and half and a third) of
the power used by an Intel equivalent.

That by itself, says nothing
A Z80 uses way less power than a pentium
A motorcycle uses way less power than a ferrari.

It says everything. Less power for the same load - google Apple M1

I prefer things designed for adults.

I very much doubt Apple can beat Intel anyway.

It\'s not Apple vs Intel it\'s TSMC vs Intel.

True, but possibly not the way you meant it. AMD is partnered with TSMC
and the Zen 3+ design on TSMC 6nm capabilities is currently kicking
Intel ass.

There is a problem with AMD. Their implementation of VT-D (virtualization to use two OSes on one CPU) sux. It slows the system right down and it\'s hard to interact with it.

Apple\'s processor is an ARM so it\'s going to be more efficient than

When comparing RISC to CISC you have to be careful to specify what
area
you\'re comparing for efficiency. Power consumption has been where
RISC
has shone. It took a while for compilers to catch up to create
optimized
code. Code size is necessarily greater, hence more RAM.

Come now, risc processors have been used for three decades now,
the compiler guys are really really good at generating quality code
for all of them.

No modern programmer is good at anything, especially tight coding.
Give
them a computer from the 80s and they\'d have trouble writing a
calculator program to fit into 64KB.

One product I worked on was a handheld pH / ion concentration meter
that
used an 8049.

https://en.wikipedia.org/wiki/Intel_MCS-48

I did the pH meter and another programmer did the ion concentration.
Reading the electrode value from the A/D and driving the user interface
was the same for both products but the math was sufficiently different
that 2K wasn\'t enough to do both.

There was also a benchtop meter/auto-titrator that used a Z-80. 64K was
a real luxury.

In reply to Scott Lurndal, yeah the compiler guys have gotten really
good after 3 decades...

I have a mouse driver that\'s 130MB. WTF? That\'s over 3 times the size
of the hard disk on a PC I had in 1991. What does the mouse driver do?
Watch for left and right and a few button presses? In 1991 I think it
was 30KB. 4000 times less efficient programming, we\'ve really come far.

I looked at Java back in the late \'90s. It wasn\'t too bad but as it grew
performance went into the toilet. The answer was \'you need a newer,
faster machine.\'

Over twenty years of hardware improvements and Java apps still suck.

I bought an Osborne 1 in \'81. It was a CP/M machine and came with 2
single side, single density 5 1/4\" floppy drives for a massive 90 KB
each. I later sent it back for the DD upgrade. Some how 90KB was enough
to hold Wordstar, SuperCalc, or the BDS C compiler executables which
happily ran in 64KB of RAM.

Somehow Turbo Pascal managed to compile so fast that at first I thought
it was broken compared to BDS.

Excellent movie but relevant how?

The film shows how people gradually became stupider. The same is happening with programmers because they don\'t have to fit their programs into tight RAM allocations any more.

Security videos can be huge, I have two 4K cameras running continuously,

So they\'re finding out about body cams. No auto delete after a month
either. It can be years before the case comes to trial and they have to
produce the camera video.

You can turn them off.

That feature may go away; they\'ll have to get more creative. Currently
some bodycam systems vendors turn the camera on when the officer gets
within a specified distance from the incident. That, of course, also
implies the body camera is a radio collar for the cop.

I thought they could be turned off out of respect for something, eg. they\'re talking about a deceased relative.

Of course your arm could always get in the way.
