> ed commands are very similar to vi commands at heart
vi was build on top of ed.
Ed was the Unix line editor, which is why all the commands after a colon have the form of "start,endcommand", eg "1,$p" would list all the lines of a file on your tty/decwriter.
1,$s/findexp/replace/g would s ubstitute all examples ("g") of findexp on the lines 1 through EOF
And these all pretty much came from an era before glass display were (affordable) in computers. A terminal was roughly a keyboard and a printer attached together, or a typewriter cut in half. Paper. No cursors. No arrow keys. Mostly after punched cards and mostly before transistors. And that was only a few decades ago, there's people still alive that have used these machines.
Funny that they are still some of the most efficient and powerful interfaces.
I started out at school in 1977 on a PDP-11 with 16K of RAM, 3 ASR-33s connected by 20ma current loop. We also had a VT-52. All running at 110baud. No valves, all transistors and ICs. That system was already outdated.
Punched/mark sense cards were still around.
Two years later we had a PET, Apple-II, and a TRS-80.
Teletypes have been around since the 1940s.
Cut the false history crap when it's easily found online and elsewhere.
Patterns are needed for languages for which the actual underlying concept is unavailable.
For example, prototype pattern is for languages that don't have a way to express interfaces/traits etc as something that can be attached to other language entities.
I'm Australian and just had to age verify on X/Twitter. They used some app called "selfie" and took a pic and said I was verified. That was it.
This social media ban is not so much about banning kids from social media.
It's more about banning social media apps/companies from accessing kids.
The SM apps are entirely about exploitation of their audiences via algorithms to push advertising and political positions. That needs to be stopped.
This is a start.
It's a bit like the bans on under 18 (Australia) drinking without supervision. We know that the bans aren't "perfect", but they work for the majority of the time for the majority of the kids.
The pathetic part of EVs is that they should have been issued by whatever the business register/regulator is in the country of issue.
Not some arbitrary group like D&B etc.
The US/other countries should have ensured that each state/registration area had an appropriate cert to sign with.
It should be part of my company's annual registration/reporting expenses that they issue the appropriate certificate for "*.<mycompany>.<2LDs>.<gTLD>", signed by them (and by the TLD root cert of the nation of registration).
Companies probably prefer to use "apple.com" instead of "apple-computer-inc.co.ca.us". It's even worse if you want to use truly unique identifiers like ISIN, LEI, DUNS, or IBRN, as that means something closer to "US0378331005.com".
The point is that I (as an Australian) don't trust a private organization like D&B any more than any other organization.
Corporate existence is dependent on some form of government regulator granting the corporation existence.
If EVs are/were a good idea (debatable at best), then having those EVs issued by the same government regulator that allows corporates to use trademarks etc makes sense.
If "apple" is a trademark for computers, then Apple Computer Inc as the owner of that trademark should get an EV issued by the regulator of trademarks.
Of course, the URL should be apple.com.us or apple.tm.us.
The historical error was not requiring the US to move to 2LDs for it's com/org/net/gov/mil etc domains.
Note this is for corporate entities, none of which exist outside regulatory environments.
Containers in general as well as palletization dramatically improved the economics and port efficiency around the world.
Using containerized energy that can be offloaded and charged and swapped at ports is much more efficient way to spread the cost and infrastructure and safety around the world.
There are many ports where you really don't want any form of radiation/nuclear materials available.
Why would you bother with the complexity of containerized nuclear reactors when you have containerized batteries that can easily be loaded/unloaded by standard port facilities?
You can carry more cargo if you don't need all those batteries. If that difference makes economic sense is not yet known of course, as there are no containerized nuclear reactions that I know of.
> as there are no containerized nuclear reactions that I know of.
Even if you built one, as some people have proposed designs, it doesn't get you nuclear reactors you can just stack up on a ship or something. Containerized reactors could be convenient for getting a reactor to a remote site where it's needed but once there you'll have to provide substantial shielding for it; usually the way this is meant to be done in these proposals is digging a big hole and/or putting up earthen berms around it. And those earthen berms will be subjected to a lot of neutron radiation, so you need a plan to deal with the site after you run this reactor for any substantial amount of time; the whole site will be radioactive.
There's really no getting around this, and most of the people pitching container-sized nuclear reactors are hoping investors don't realize it. The amount of shielding that you could ever hope to place in an ISO container isn't anywhere near enough.
Reactor fuel remains radioactive even when the reactor isn't operating.
And the proposal was a containerised nuclear reactor, so you're going to irradiate the surrounding containers in the process.
Nuclear submarines and aircraft carriers are completely different beasts. The reactor core is very heavily shielded, is built into the ship/boat, and is tended by a team of expert operators, and (at least in the case of US/UK subs) uses bomb-grade uranium as fuel.
I've been "work from home" since 2012, mainly because the projects I worked on were actually in overseas cities.
Before COVID, I would go on work trips of 1-2 weeks every 2 months or so, which was more than enough "office time" to get my doses of office chatter, noisy work environments, stupid in-person meetings etc.
Even before the lockdowns (Melbourne had the longest in the world), I made it part of my routine to go outside every day to get coffee/lunch/sit-in-the-park/walk/talk to people.
It's important to have that human contact, but it's better that I get to choose who to have that contact with and when and how. There are numerous friends from my work that I also see out of work, but there are a great majority that I have no interest in being with in person or outside the work context.
I feel this is the perfect mix. Aside from a short stint at a company that didnt believe in allowing employees to work remotely in 2020 (don't ask), I have been fully remote since 2019. I love being remote, love being able to take my son to school and pick him up, etc. I do, however, cherish the two times a year I travel into the corporate office and work in person with my teammates. I wish I had the option to go into the office, not required, just a choice.
They're easy to type on a TTY.
grep is from the ed command "g/re/p" which is g (all lines, short for "1,$") /re/ regular expression to search for, "p" to print the lines.
It still works in vi.
