Re: Performance slow?
You could speed things up quite a lot by choosing your data types correctly. Once, in a quiet period I spent a lot of time working out what data type to use to optimise both storage and performance.

Written out on datasheets.
Given to the Data Prep department to be turned into punched cards.
Submitted to the operators for an overnight compile.
Next day, check errors, correct and resubmit for another compile the next night.
Once it compiled successfully, start to debug, one run a day.
Once, when the Data Prep department was busy, I produced a program on punched cards using a hand punch.
Mind you, from the article - "2 million coders producing 1.5 million lines of code a day". Must be still using the same process.
-> thinking the other person MIGHT want to see it, and if the other person says "do not send me this ever again" and you do NOT, there's no JAIL involved, just irritation and need to apologize.
"So if I whack you painfully around the head with a baseball bat, and you tell me that you didn't want me to do that, it's OK if I apologise, and I won't be charged with assault?"
It also sounds like a flasher's charter "Didn't you want to see that? Sorry - I won't do it again".
"Depends how you worked. I started at a place where we wrote on coding sheets (it was assembler) so it would have been sensible to get a fast typist to bang it in after you'd written it."
I started COBOL programming on coding sheets, which then went to the data prep girls to be typed up and a card deck produced.
You tell that to youngsters today and they won't believe you.
These were told to me in the Eighties by a PC supplier, and I have no cause to doubt them.
The first was one told earlier, where a user had sent a floppy through the post with evidence on, and a compliments slip stapled to it.
The other was where a new PC was supplied, and the dealer gave the user two floppy discs to start them off as backups. Let's call them A and B. Things worked well at first - as the data on the machine grew, floppy A no longer had enough space on , and floppy B was inserted when asked for. The problems started when the amount of data grew further. Floppy A was inserted - when full, floppy B was inserted, and then, when full, floppy A was inserted again....
Once slept at a friends flat which had one of those motion-sensor lights in the wardrobe. I like to sleep with the window open, and every time there was a gust of wind, the wardrobe doors moved, which turned the light on. As it was a friends place, I didn't want to dismantle the light.
"At its heart he's denying the value of predicting the actions of others. I know I predict while driving - constantly and unconsciously, using judgements of their position speed and acceleration, but also the make and condition of the car, the age and sex of the driver, where we are."
Of course you are. The central premise of driving is that you only drive into a space that will be empty when you get there, which involves the prediction of what everything around you is going to do. If you just drive by reacting to others, then you are an accident waiting to happen. In fact, I am not even sure that is possible.
I don't particularly mind targeted ads, if they are targeted by FB (I did sign up to that bit). If an advertiser gives FB an advert for 40-50 year olds who like eating out, and FB puts it on appropriate time lines, then that is ok with me. What I really don't like is other companies being given data about me to effectively do what they like with (I didn't realise that I had signed up to that bit). That is the main reason I am trying to wean myself off FB.
The basic problem with the surveillance society is that people don't care that they are being watched. "If you are doing nothing wrong, then you have nothing to worry about" is the quote I usually hear when discussing it. "Who is going to be interested in what we say?" was the reply when I discussed Alexa with someone. When all that most people see is a few targeted adverts, they will live with that if it means they can share photos, news and memes. I am seriously considering coming off Facebook, but I will then lose touch with many people that I do not communicate with in other ways.
It won't do things automatically.
“a visitor can sit on a piece of Nattuzi furniture and tell it to turn on the TV. It will then activate the LG Signature OLED TV while the sofa and light are adjusted for the best viewing experience.”
So you have to tell it what to do. I'd still rather use a remote, though.
In the 80s, the company I worked for set up a multi-user data prep system It ran on an IBM AT PC (with a 286 processor), had a 20 (yes, twenty) MB hard disk, and supported 6 users. If you told the kids today that they wouldn't know what you were talking about, let alone believe it.
"When I started learning IT at school, a lot of attention was paid to punch cards, kimball tags and other almost obsolete tech which I saw hide nor hair of when I reached work a year or two later."
When I started work, my first COBOL programs were on punched card. I even produced one with a hand punch, because the data prep department was busy.
You got one compilation run a day in those times.
I can see two problems with that. The first is that most people would want a truly driverless car (not the kind where you have to pay attention to take over) so that they can drink, which they couldn't if they had to drive at both ends of the journey. The other is that the most stressful parts of a journey tend to be the town bits at the end - the motorways are relatively stress-free.
Many years ago we polled sales data from stores overnight using Kermit over a modem - I said it was years ago. We had one store that would always fail, and then work on the retry, some hours later. Eventually we put someone in to watch what was happening, and, at the time we should have been polling, the cleaner was in, and unplugged the modem to plug the vacuum cleaner in. When finished, the modem was plugged back in, hence it worked on the retry.
It hasn't replaced books for me - I still read real books in bed, but the Kindle is great for holidays. Long battery life, plus the screen is much less tiring to read than a phone or tablet.
I can also have the Kindle app on the phone for journeys, and it stays synced with my actual Kindle.
-> No it's not. Bala Lake is a natural lake and 3 times the area of Llangorse. I am sure there are other reservoirs larger too.
Absolutely right - it doesn't even make the top 10. However, it is the second largest natural lake in Wales (after Bala) and is the largest in South Wales.
