The helmet protects the ears from direct airflow noise, but it also extends out into the high-speed airflow much more than ears do.
The overall picture is that a helmet’s thick material blocks high frequencies. But it exacerbates and amplifies low frequency sound and white noise. As well, a helmet confuses the ear’s capabilities for identifying direction of sound that’s incoming
If a helmet is helpful is a question of how fast the motorcycle is moving and what kinds of sounds the rider needs to hear.
It’s complicated, but wearing no helmet might be safer at low speeds because the driver is more aware. No helmet, is undoubtedly not safer at high speed because brains are fragile
Edit: a simple experiment for anyone is to put on a full size motorcycle helmet anywhere, and then you can understand how much your hearing is dampened by it. But I guess it’s probably no worse than the experience of someone driving a car, which is soundproof by design
People who believe they are financially secure may move from regions which are considered “wealthy” to regions which are seen to be “poorer” (and cheaper). This outflow can influence this data.
>writing a few thousand lines of assembly was what it took to launch a successful software company.
Yes, but that assembly was not DOS, and it wasn’t easy.
Microsoft purchased the DOS code, they didn’t write it. Of course, they did develop and modify DOS. But that was a clever (and lucky) business deal, not a technological accomplishment.
The real beginning of Microsoft was earlier, with Allen, Gates and Davidoff writing the Altair BASIC interpreter. That was a serious achievement.
They had never seen the computer they were writing that assembly code for. They did not even own any computers. It took them 8 weeks on a university computer they were not supposed to be using for that
“Altair agreed to meet them to possibly buy a BASIC interpreter… Gates and Allen had neither a BASIC interpreter nor even an Altair system on which to develop and test one. However, Allen had written an Intel 8008 emulator that ran on a PDP-10 time-sharing computer. Allen adapted this emulator based on the Altair programmer guide, and they developed and tested the interpreter on Harvard's PDP-10.
The finished interpreter, including its own I/O system and line editor, fit in only four kilobytes of memory, leaving plenty of room for the interpreted program. In preparation for the demo, they stored the finished interpreter on a punched tape that the Altair could read, and Paul Allen flew to Albuquerque to meet with Altair…
While on final approach into the Albuquerque airport, Allen realized that they had forgotten to write a bootloader to read the tape into memory. Writing in 8080 machine language, Allen finished the program before the plane landed. Only when they loaded the program onto an Altair and saw a prompt asking for the system's memory size did Gates and Allen know that their interpreter worked on the Altair hardware.”
That iris style physical security filter looks very cool, and it’s neat because it’s protected from damage, but a simple one-piece sliding or folding shutter would be so much more reliable
No, because then the rocket would probably launch in the middle of the sentence. He had to start saying that sentence at the right second and pace the words and his movements perfectly.
This is quite like saying that because you’ve “aged out” of high school, you must be suddenly cut off from interacting with all the friends you made in high school
IRL, you stay in touch with some of those old high school friends for years.
I don’t know if it’s the Roblox system deliberately trying to prevent players from maintaining contact outside the game with their friends? Or maybe just that the players haven’t foreseen the need to be ready for the abrupt cut in communication on their next birthday? (Happy Birthday!)
Sounds like a serious strategic error by Roblox though.
The UI is almost perfect, it’s seamless on mobile and desktop.
I made some criticism in other comments therefore I also wanted to make a comment saying what I liked.
