Why Not Use 64-bit OS on RPi Model 3 and 4?

Bill now denies ever saying it, but somebody probably did!
Even if Bill didn’t say it, DOS was certainly written with that assumption in mind.

Also the limitations on the amount of RAM that the 8086 CPU could address. Remember that when the IBM PC was being designed was right around the time of the Apollo moon landing which used a mission control computer with only 64K of RAM. Giving end-users 100 times that seemed reasonable, especially considering that DOS applications were really small with very low memory consumption compared to now.

I am always asking myself why more and more think for a simple news a 10 Minute Youtube video is required.
Same with these unboxing videos. Why do i need to watch somebody unpacking something?

Well, never mind, just my humble opinion.

Some people are visual learners. More and more actually… because exposure from young age to this media.
Reading typed words became something… abstract for them, the nature of writing requires a bit more imagination than video. Sadly, that’s what internet brought to human race.

PS: Irrelevant for this post, but this is the trend that I see, at least in US. My wife is special reading teacher for 1-4 grades. If before there were like 3 kids in a class that required special attention (to reading), now there are 3 that… don’t. Online learning produced 2 years of illiterate kids. Second graders don’t know letters at a kindergarten level.

Version 7.2 of arm64 piaware, dump1090-fa, dump978-fa, and piaware-web, and beast-splitter available now

@obj, @eric1tran
In both cases tcltls-rebuild (tcl-tls_1.7.22-2+fa1_arm64.deb) is built and installed

Seems 64-bit RaspberryPi OS is gradually gaining popularity

Off Topic - Guess What This Is.

Hint: picture was taken in 1956… Answer below

 

It’s a hard disk drive back in 1956.

In September 1956 IBM launched the 305 RAMAC, the first ‘SUPER’ computer with a hard disk drive (HDD).

The HDD weighed over a ton and stored a ‘whopping’ 5 MB of data.

Do you appreciate your 500GB / 1TB / 2TB SSD a little more now?

There’s nothing inherently wrong with having a different learning style (the material in a course of study is typically presented in textbook reading assignments for the readers, lectures for the talkers and discussers, and lab exercises for the hands-on doers. It I’m not mistaken these three types of activities use different parts of the brain, so the educational theory seems to be to cram the knowledge into as many different parts of the brain as possible and hope it sticks to one of them)

People who can’t read a story* and picture the scenery, characters and situation in their mind’s eye need to spend a few weeks or months off-grid with no electricity, television, Internet or cell service, just a stack of good books and a light source of some sort.Otherwise, with absolutely no imagination or creativity they’re going to end up having jobs where they wear shirts with their names on them.

*The dyslexic are another matter entirely as their inability to read is an actual physiological issue, not a mere lack of interest and imagination. (“Books are boring. Let’s watch a movie instead.”)

There may be other factors also (which I cannot make out) but apparently it looks like that on 64-bit Raspberry Pi OS, the 64-bit piaware & 64-bit dump1090-fa use less CPU (even when dealing with higher traffic) than 32-bit piaware & 32-bit dump1090-fa on 32-bit Raspberry Pi OS.

Can anyone shed some views / clarification?

Better CPU optimizations. armhf includes old arm CPUs that can’t do vector instructions, aarch64 doesn’t.

Am I right to conclude that on RPi Model 4, installing 64-bit OS + 64-bit packages gives better CPU optimization, compared to installing 32-bit OS + 32-bit packages?
