Comment Re:Nobody mention TAI (Score 1) 91

I never said to adjust it only once. For scientific use time should be specified as TTTT:TT:TT:TTTTT - PPPPPPPPPP where PPPPPPPP is the periods of cesium per second used for that measurement. For everyday use no need to distinguish the varying time 'constant.'

That was tried before 1972. The frequent adjustments of the length of the second became cumbersome to track, so the in 1972 the switch was made to the current system of constant length seconds with leap seconds to keep UTC tracking the rotation of the Earth..

Comment Re:good thing I guess (Score 1) 91

When I worked for a broadcasting software company that had customers worldwide, everything was using TC (timecode), PTP, and of course we needed to support leap year, different timezone etc when a broadcast was scheduled between different zone around the world (it can be complicated) ; and we needed to support leap second by contract! Easiest thing was to add a 1s black frame after the schedule after reaching midnight. Supporting negative leap second would have been complicated... Good thing we drop it I think.

That's very interesting.

To support negative leap seconds you can insert one second of black on normal days, two seconds of black on days with a positive leap second, and no seconds of black on days with a negative leap second.

Atomic time is based on 9,192,631,770 periods of cesium? why not adjust the period count to not require any leaping? Fix the damn problem at the source and be done with it. This new strategy is just in accordance with the lazy do-nothings. Most networked time is synchronized for local clock drift constantly, most chips are simply not that accurate, so change the source clock and they won't even need to be fixed as the constant syncing corrects for such a small change automagically.

That won't work because the rotation rate of the Earth is not uniform. No matter what you pick for the length of the second, the Earth will not always turn in 86,400 seconds.

It is 9.7km/kWh, which is indeed impressive. My 2025 Equinox EV is 5.1 km/kWh, but is a much bigger car. My husband's smaller 2017 Bolt EV is rated at 5.7 km/kWh. In the real world, the Equinox actually uses less than the Bolt because of the heat pump.

My 2018 Nissan Leaf gets 5 km/kWh in the winter, 8 in the summer. Unlike the cybercab it is driven manually and has room for four in addition to its turnk space.

Comment 2000 Honda Insight (Score 4, Informative) 304

In the year 2000 I bought a Honda Insight, an early hybrid. I was surprised to find that it had start-stop: when I stopped at a traffic control signal it shut off the motor, then started it up instantly when I pressed the accelerator. A few times the driver of the car in the adjacent lane looked startled when the sound of my motor stopped.

The Insight had wonderful fuel economy. I once got 73.5 miles per gallon on a 109.4-mile stratch of Interstate 90.

I used that car as my daily driver until 2018, when I traded it in on a Nissan Leaf, an electric car, which I drive today,.

I, Steve Wozniak, did not participate in the theft of the BASIC. It was funny to me to see others enjoying doing this. I had never used BASIC myself, at that time, only the more-scientific languages like Fortran, Algol, and PL-1, and several assembly languages. I sniffed the air and sensed that you needed BASIC to sell computers into homes, because of the book 101 Games in BASIC. I loved games and saw games as the key. It was the [MS] BASIC that inspired me to write a BASIC interpreter for my 6502 processor, in order to have a more useful computer.

Section 230 needs tweaking. Any platform that alters or removes postings that are 1st amendment compliant should be deemed a publisher. Adding context or community notes is not an alteration.

It is hard to draw this line in a way that does not open the door for the rich and powerful to suppress speech they don't like. If I do line-wrapping on your text, but leave the individual words unchanged, is that an alteration? What if I add a footnote that exposes a lie?

Remember that a rich person does not have to win a lawsuit--he can drag out the proceedings to the point that you are unable to continue defending yourself. Even if you are eventually exonerated, the process is punlshment enough to deter others from doing what you did. Section 230 provides an early out in such cases.

At every level of speech expression, there's a corporation involved. Nobody exists on the internet without any at some point.

While that is true, I come close to being able to express my ideas on the internet without getting permission from a corporation. My web site is on a computer in my home. I depend on my internet service provider, but unless they monitor my web site directly or break TLS 1.3 they don't know what I am saying. I depend on a company to host my A DNS record, but they also host my MX DNS record, which is needed for e-mail. I don't use a content delivery service: when you access my web site the information is send to you directly from my home.

Of course, my greatest protection, which almost everybody shares, is that nobody who is rich and powerful cares what I say.

The average consumer doesn't care about this stuff. They'll happily do whatever they're prompted to do, because it makes life simple. Using vi to edit Makefiles so that they can compile and install a new driver for their favourite USB wifi dongle...not gonna happen.

To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. Nothing but the truth should be spoken about him or any one else. But it is even more important to tell the truth, pleasant or unpleasant, about him than about any one else.

Teddy Roosevelt May 17, 1918

Roosevelt spoke these words in Kansas City on May 7, 1918, no doubt in part to justify his extreme criticisms of President Woodrow Wilson, whom he excoriated for moral flabbiness, for high sounding words unmatched by action, and for not preparing the people of the United States for entry into World War I.

Being able to talk to the computer to ask it to find things based on meanings is like Star Trek technology and it's sad in a way that the hype is distracting from what they're good at. For example, yesterday I had a problem (not tech but a field I know nothing about (oh wait like tech then)) and the first AI search I did gave me an excellent find. Maybe I would have found it after spending all day browsing, but this was a great answer. And what about when we were supposed to wait for the semantic web and all that. So it's a bit sad it gets hyped as being able to replace people.

I hope you checked the answer. AI can give excellent-looking but totally false results.

Comment Re:Code review, not fun. (Score 2) 86

On the other hand, 'code review' is one of the things that really splits senior software developers from the lower levels. Just being good at programming makes you a good programmer. Reviewing and signing off on other people's work is what (generally) makes you a senior or a lead. Probably the number one complaint I hear from senior devs is that they miss coding since so much of their time is spent doing reviews.

When I was at DEC code reviewing was not limited to the senior software engineers--we all did it, both as reveiwers and reviewees. I enjoyed the process, probably because it let me demonstrate my skills to my peers.
