Have you Seen “I Saw the Future” by Artem Kubatkin

@timorl Wonderful, thank you!

@shibaprasad @Full_marx @hansw@mastodon.social
After the mainframe and Fortran, punched cards time, my next experience was with an early home computer, a Sinclair Z80 clone, and it was not the best thing to type on.

Things change a lot, certainly. 😃

@shibaprasad It's worth keeping things we download, as the newest is not always the best.

I should have known better, just had an example yesterday, BlueStacks Android breaking what was a perfectly functional installation here with a version upgrade. Never had seen it crash before. Ugh.

@shibaprasad @Full_marx I forgot to mention the other highlighted box, on the right side of the card -- it was the project number, so if you dropped or mixed the card you could still find where it belonged.

@hansw@mastodon.social
Wasn't it lovely? 😄

@shibaprasad
Thank you. Brings back some nice memories. 😄

@Full_marx
A nicer photo, showing a used card and details.

We can see the card's instruction, I highlighted in green :

Z(1) = Y + W(1)

In English, it takes a lot more wording to transmit the instruction, but I believe it would read as: "Let array Z, cell 1 be equal to variable Y plus contents of array W, cell 1"

...where Z and W were previously defined and initialized as single dimensional (think a straight line of mailboxes, each cell contains some value you chose to store there) arrays.

It's been a long time, Fortran. 😉

@Full_marx Librarian in me says...

@shibaprasad I support your recommendation, having used it for years too.

Hint - the older versions of Foxit Reader are smaller, simpler and work well. They are still available if you look around.

Definitely NOT Adobe Reader or what have you.

One line of computer programming, whichever language you were using. Up to 80 characters wide, same as the card's width.

I remember. And we loved it. No home computers, no cellphones, no internet. Mid 70's in my case.

@_lunawinters A plan starts with a dream and an aspiration. Go for it.

@dayvancowboy @raining_night

Even before Edward Snowden's revelations and supporting evidence, there were persistent rumours for years that taps had been set into some of the largest Internet exchanges.

Like the one in San Francisco, which was the incoming point for various trans-Pacific fiber links. Rumour had it that some federal organ had leased an entire floor below the exchange, and installed hardware above mirroring ALL traffic to their own floor. For processing and archival uses apparently.

@stux Yey, glad to see I am in good company.

The Dark theme is indeed the only one to go and keep your eyes for longer sessions!

@dayvancowboy @raining_night
I think those devices are very risky, considering who is selling them and their geo location and legal jurisdiction. Plus the character of the federal administration.

No thanks for me. But any mobile device could be spying on you as well, unless you removed the battery completely (why would manufacturer's have removed this option on newer models, eh?) or place them inside a shielded room (cutting off radio all together).

@_lunawinters You are very welcome. 😉

The country is also accepting immigration - it's possible to apply and get a permanent residency Visa if you either have a source of income aborad (investment, trusts, or pension income) or if you have a plan and want to start a new company.

A lot of European digital nomads are making Lisbon home.

Suggestion, get the Lonely Planet Portugal Guide, it's a good read and geared to travellers like us.

Or look at their website, just found this :

https://www.lonelyplanet.com/portugal

I downloaded a ebook copy of their guide from my local Library, and refered to it for the 3 weeks loan duration. Having been there before, I did it lightly, to find suggestions on cities I was not too familiar with, but the guide is solid and fun.And it you want to talk about it, I will be delighted to oblige... 😄

@Rovine
I learn Trig on the blackboard, when we used printed bookform Trig tables for each angle value.

The concept is in my mind, and I visualize the circle on the board, radius 1 unit, and sine and cosine being placed cleanly, one on each axis.

Perfectly rational and memorable.

Tangents were fun and intriguing, shooting up to infinity as the angle increased to near 90 degrees.

Geometry and math are lovely.

@freemo

Chalk and a good blackboard. And a talented genius at work.

Professor Einstein's note and office blackboard pics.

@_lunawinters That's exactly like I like it too.

Lisbon is a wonderful city in all senses, and it's enchanting to discover and explore on foot.

I have visited the country for the last 3 Springs, and still came back home with about 3,800 photos from this last trip.

Costs are affordable, I stay in hostels mostly, eat on small local eateries, and spend somewhere in the 20 to 30 Euros per day for food and accommodations.

That allows long stays, the way I like, and exploring the country in detail.
