I saw somebody's arduino based voltmeter clock way back around 2014, I think here: https://maniacallabs.com/2014/07/08/meter-clock-pt1/

I thought it was pretty cool, but a bit expensive for what it was.

So I made my own with a PIC chip: https://www.n1kdo.com/meter-clock/index.html

Mine is more of a novelty than a accurate clock. It is a interesting desktop geegaw to invite discussion.

That page does not include VMS DECwindows Motif, so here is a link:

https://www.xanthos.se/~joachim/OpenVMS.html

VMS DECwindows Motif 1.0 was released in August 1991; it is difficult for me to comprehend that was 35(!) years ago. I still have a mouse pad from the release party.

Only Boulder servers lost sync.

To say NIST was off is clickbait hyperbole.

This page: https://tf.nist.gov/tf-cgi/servers.cgi shows that NIST has > 16 NTP servers on IPv4, of those, 5 are in Boulder and were affected by the power failure. The rest were fine.

However, most entities should not be using these top-level servers anyway, so this should have been a problem for exactly nobody.

IMHO, most applications should use pool.ntp.org

IMHO, "tech optimism" reached its peak in 1969 when Armstrong and Aldrin landed on the Moon.

We watched them walk on the Moon on live TV.

After seeing them perform that impossible feat, it seemed like we could use technology to do anything.

As far as the Digital and/or Internet revolutions, the changes have been so fast and widespread that people have not come to terms with them, at least I haven't, and I've been pretty deep into both.

My particular concerns are around atrophy of basic skills (reading, research, writing, etc.,) the authenticity/trustworthiness of "knowledge" obtained from various Internet sources (misinformation, fake news, deep fakes,) and lack of personal contact and interaction in a world where peoples' only connection to others is through a screen (fakebook, instagram, tiktok, etc..)

AI is not going to make any of those any better.

I would not describe my feelings as "dismay" or "fear" but rather of "extreme caution" -- if that makes any sense.

With that said, I'm going to step away from this computer and go play with my dog.

I have taken three of those classes as part of the Online Master of Cybersecurity program. They were all excellent. I can say that the assignments were an important part of the learning experience, for instance the practical experience of attacking weak RSA keys.

I would not let the lack of assignments, tests, and quizzes stop you from trying these if you are interested. At a minimum, they would give you a feeling for what the program/s are like, and possibly encourage you to enroll into the online degree program, which is an exceptional value.

How many times has this problem been "solved"?

DCE/RPC worked in 1993, and still does today.

Protocol buffers is just another IDL.

This is highly relevant:

I still have a PDP-11 Programming Card I bought at that Digital retail store. That was an interesting place. As I recall, there also was a AT&T store in that mall where you could buy... telephones.

This book: https://en.wikipedia.org/wiki/BASIC_Computer_Games

I was exposed to this book in about 1975 when I was in detention in the math teacher's room. It set me on a path to programming.

The list does not include DECterm.

Maybe it's hard to find these days. However it had the best VT220 emulation I have seen running on X Window System.

I will note that I have not seen a terminal emulator that supports the "double wide" and "double high, double wide" character modes of the VT100. Those giant letters were kinda fun. (<esc>#3, <esc>#4, and <esc>#6 if my memory serves me right.)

It's not just radio towers. I've seen aircraft warning lights on tall buildings, particularly those near airports.

The TL;DR is that there are malicious browser plugins that make the browser into a web scraping bot.

I see this all the time in web server logs; it is recognizable as a GET on a deep link coming from some random IP, usually residential.

Some businesses are still using DEC PDP-11s, first released in the 1970s. Those are even more "ancient." Many of these are used for industrial controls, among other applications.

see: https://news.ycombinator.com/item?id=30505421

The article does not mention what OS is being used, but RT-11 was designed for "real-time" applications. That was released in 1973, so over 50 years ago.

Thanks. I'll stick to a walkie-talkie. FRS radios are cheap, easily obtainable, and will work as far or farther than this 915 MHz stuff.

If you get into deep shit, some amateur FM handy-talkies are IMHO more likely to be able to get you help. Or perhaps T-Mobile's T-Satellite service if you are headed somewhere really remote.

Unpopular opinion: Meshtastic is a solution in search of a problem.

They were inexpensive when compared with a VAXstation II/GPX!

It was the interoperability of X Window System devices that enabled this.

Your X server (e.g. a X terminal) could display applications running on a variety of other vendors' hardware and operating systems. The specification enabled this interoperability. Apps running on SunOS could display on VAX workstations, and vice versa (as long as you had TCP/IP installed!)

The advantage X terminals had was that they were relatively inexpensive to buy and operate. Most did not require management, however the CPU cost moved into a computer room and you needed a pretty fast network to get reasonable performance.

I can tell you that lights strobing exacerbate my migraines. Even 120 hertz from fluorescent lights will affect me. I have mitigated this in the past by adding incandescent lights in my office, or demanding to work near a window. LED lamps are no good, as another commenter posted, even the simplest ones strobe. Incandescent bulbs grow harder to find as time goes on. Progress?

my understanding is that the area is still a bit "hot" with radiation.

My recollection (which could be rusty, it has been >30 years) is that the Motif API, coded in C, implemented a kind of polymorphism.

VAX Notes. Perhaps the original groupware. Not really useful without collaborators any more, since DEC is dead and took that cultural fork with it.

One should not forget how the FCC gifted the bottom of the 220 MHz band to UPS, who never used it.

I have a better idea. Take the old UHF TV channels 70-83 that were re-allocated to AMPS cellular and re-allocate them again.

I have had this for a very long time.

Shannon did a lot more interesting things than just this paper.

If you become more interested in Claude Shannon, I recommend the biography "A Mind At Play"

https://en.wikipedia.org/wiki/A_Mind_at_Play

A very interesting person.

WTF is "Proverence"? I'd call it a typo except it is consistently misspelled.

I think the author means "provenance".

https://www.merriam-webster.com/dictionary/provenance

I disagree with the whole typeface (font) selection discussion in the article.

You want people to read your slides? Don't use a hard-to-read typeface.

Before building a "deck" for a presentation I suggest reading Tufte's "The Cognitive Style of Powerpoint" (https://www.inf.ed.ac.uk/teaching/courses/pi/2016_2017/phil/...)

It would be useful to list IP ranges that the scans come from -- a lot of my web stuff has "hosting providers" firewall dropped because so much malicious traffic emanates from the hosting providers (Do you hear me, Digital Ocean and AWS?)

I'm not an EE, but I play one in my home lab.

I don't understand why this circuit needs an artificial ground at all, since the power source is two 9-volt batteries in series. AFAIK that could make a dead-simple bipolar power source +/- 9 volts and get rid of about half the parts.

The 10:1 voltage divider is also an interesting concept. It seems to me that what this thing does is attenuate the input signal and then provide a low impedance output to drive the 'phones. I wonder if the writer ever considered something as simple as shunt resistors.

Perhaps a "real EE" can enlighten me.

FWIW, I use a AudioEngine D1 USB DAC to drive headphones from a computer. It was not cheap, but neither is my time. For portable use I am rocking (with RockBox) a old iPod "video" with aftermarket SD card mod.
