EE rant

Yes, DC restore works on digital data, given that it's not a very long string of 1s or 0s. Most telecom waveforms are balanced and AC coupled and have AGC. And assive adaptive equalization.

They are likely in bed with hardware manufactures to stimulate sales of faster PCs and in bed with providers to sell faster internet. ?

And then people complain the US doesn't make electronics anymore. Challenging programs with a high washout rate AND it doesn't pay too good? Wow hard to believe everyone isn't jumping on that one, lol

'lol' doesn't make things funny to anyone but you.

Of course the US makes electronics, just not the incredibly cheap and junky consumer stuff.

If too many kids with no hobby background and no aptitudes decide to enroll in EE schools, it makes sense to wash them out so they can do something else. All the hard stuff has high washout rates. Let them study journalism or sociology or something easy, or become something useful like a carpenter's apprentice.

The idea that everyone should go to college is dumb.

modern packages are not really an issue when places like JLCPCB does multilayer pcbs and assembly for the price of a cup of coffee

a pile of boards and wire in a Tupperware container? ;)

I advise younguns against an engineering degree, it's over-specialized, and obsolete in 5 years.

I tell them to get a physics education. Study hard. Then you have the tools to do anything you want.

That is, first the academics, then the vocational training.

The world will always need engineers.

And why should an engineer get obsolete? One fun thing about engineering is that it keeps changing, so we get new toys and new tools. The fundamentals don't change.

What sorts of careers do physicists have these days? I mean, aside from teaching physics.

Do you have a physics degree? What do you do?

Seen here stacked: a WRT-54g and WAP-54g were interlinked and sealed inside Tupperware there was only a power lead.

Only if you get sucked into spending all your time on the flavor of the month. People who spend their time in school learning fundamental things that are hard to master on your own (math, mostly) and then pick up the other stuff as they go along don't get obsolete. That's not difficult to do in your average EE program even today, AFAICT. Signals and systems, electrodynamics, solid state theory, and a bit of quantum are all good things to know.

Spending all your time in school programming in Javascript or VHDL or memorizing compliance requirements is not a good career move for an EE.

Physicists turn up everywhere, it's true. Folks with bachelor's degrees in physics can do most kinds of engineering, provided they're willing to bone up on the specifics. Of course there are some who assume they know everything and just bull ahead till they fail, but, well, human beings are everyplace. ;) Thing is, the basic professional qualification for a physicist is a doctorate, whereas in engineering it's a BSEE.

I agree that knowing the fundamentals cold is very important. However, (a) physics isn't for everyone, by a long chalk; and (b) there's a glorious intellectual heritage in engineering, so calling it 'vocational training' is pejorative.

Are you sure about that? Is it a very recent thing (as in failed 27/12/22 by any chance?)

POP worked fine on MS Office 365/Outlook with the server settings here:

If your ISP has done it the same way that mine has (outsourcing).

Your problem might be that your ancient email client doesn't support OAuth2 and things stopped working in October when they enforced that. Also check that your ISP has provided a sane default SPF record for your domain otherwise emails sent to BT or other MS users will be dropped on the floor ! Mine didn't :(

Not a good idea to let your domain name lapse much better to transfer it to somewhere else (but unless they have usurious renewal fees it doesn't really matter). Hosting can be with an entirely different business and is usually sufficiently trouble free that cheapest deal wins hands down.

interesting but godddy has done more things wrong, this was the limit

I take the website away from them, never mind the domain name, panteltje.com, panteltje.net panteltje.org panteltje,eu etc etc what difference does it make to me? It is all open source stuff and some things I showed here.

I have now set an other free pop email account I have as primary and everybody that matters has that now. I vote with my purse (is the expression); godaddy lost a customer. I cannot tell them as their phone helpdesk does not even work, so setting auto-renewal to zero was my vote.

And I do not like microsore reading my email, might as well sent those to the seeeyeaa! Imagine they find out I have that old USSR submarine and am testing those air-mail tubes..

:-)

It is all about FREEDOM, microsore is just like a kraken with tentacles pulling you in. There is NOTHING they give that does not exists for free AND better!!!!

You are better off using PNG files with a restricted palette for circuit diagrams. Smaller and if done right you can get away with at most 4 shades and if you want to be really brutal just 2. I have a greedy algorithm based colour reduction method that works really well.

I'm astonished at how bad the ones in PSPro and Photoshop can be when faced with line art on a slow gradient uneven background. Preserving all the wrong things at the expense of the important details!

Slightly silly of them but it shouldn't affect updating since the new file date will be more recent than any older file.

Increasingly you can't have a catch-all with any of the modern email systems - too much spam goes to non-existent addresses. On any decent configuration you can set up a whole bunch of aliasses - Demon on Namesco now running on Microsoft Office365 server allows ISTR 250 (which was more than enough for my needs)

It did I grant you require a complete rewrite of my sorting rules on the email clients at my end but that was a one off PITA.

Fair enough. I have found not paying for service not provided does eventually get bad ISP's attention but you can get demands for payment if you don't notify them >30 days before renewal.

Whilst I am no great fan of Mickeysoft their 2022 C++ compiler can run rings around both Intel DPC++ and GCC for highly optimisable code.

Industry sets the requirements. Used to be supplied from the boonies. Now they're just imported or contracted offshore, like every other commodity.

Yes, I do that sometimes.

It is amazing how good the pictures of my Xiaomi smartphone in 48 mega pixels mode are... But hard to get those of the phone, so normally I just snap things with my Canon and then put the SD card in the laptop, use a script that sends it to the webserver and also to the backup.

Ultimately I could write my own email server and run the webserver at home as I did 20 years ago. But lots of things security related have changed, including the name server stuff. Too much work, checking the logs for attacks (sometimes hundreds at the time in those days), more interesting things exist. Would require a fixed IP address too... Now I am just 4G portable.

Oh, changed that in November, thing expires in February.

I have little experience wih gcc and C++, only use C, latest gcc had problems compiling my stuff when porting to Raspberry Pi4 (ARM), but found a solution online (was not the only one with problems). Re-writing the makefiles was needed .. It is not fast on Raspberry but OK I do not write that complicated code (I think).

I was 'called in' by the landlord of my business unit, to replace a bathroom light bulb. . . . . for a CNC machine 'programmer'. Advised him not to mention this to anybody at work. Used to be a joke about this. Not so funny any more.

Also called into another business to 'break in' a new production line tester/troubleshooter. He didn't know what the color code was. I guess he knows it now. Local tech school graduate of recent import.

Not so different in 'tech schools'. George Brown would enrole 60 and graduate 6. A lot of the fall-out was to students who just couldn't wait for a paycheck and were offered work 'as is'. Sometimes a negotiation for a related certificate was possible before bailing in the later years.

RL

I use Rackspace for email. Catch-alls are allowed, no problems.

I haven't been keeping up, but for my clusterized EM simulator, circa

GCC has got better at that, but you have to write inner loops in a particular, very simple style to get any benefit.

I've been thinking for some time now that EE schools don't turn out

I've known onshore theoretical physicists who had to be shown how to hammer a nail into a 2x4 without bending it. So it's not super recent.

And of course status-conscious places are miserable to work in. Give me an outfit where folks just want to get the job done, any old time.
