Thanks for reminding me of that- it's been a frequent news topic recently. I know I would have done better in school with an extra hour of sleep. I know I know, "go to bed an hour earlier". Well, it doesn't work no matter how hard I try.
The only source of potential pushback I'm aware on this is parents who don't want their kids waiting for the bus in the dark...
As far as I know / remember, that is the only reason we change the clocks. In this modern age of cheap bright LED flashlights, I don't know if it's such a big deal.
But a better solution: let the kids start school an hour later and go home an hour later. I'm not sure if this is true now, but years ago most juvenile crime was committed after school and before the parents get home. So it may be a win-win.
Oh, worried about after-school outdoor sports, etc? It's okay, let them continue what they're doing now, and adapt indoor / class schedules. It can be done.
Wow, very interesting. For much of my life I've had great admiration for UK and your technical prowess. I often think every Brit owns a soldering iron and can build a simple radio without plans. You did great things in RADAR development in WW2, computing, codebreaking, etc. Everyone wants a British electric guitar amp, and being an audio buff, when I did some research for an EE college audio project, I found the UK stuff to be the best and I learned a lot. I assumed you designed and built your reactors.
Rally the troupes! Design better reactors! Build some! Tally Ho!
Don't cut corners. Enforce good project management. Fire lazy / inattentive people who prefer to drag their feet, inflate costs, cut corners, etc. Streamline the oversight / review process. Make it agile.
I don't want to say too much, but I'm working on a small project that's part of the reactor monitoring system. Frankly I see some errors in the design, which is 40 years old and went through years of a very expensive design review and approval process. I'm not allowed to change anything, even though there are some errors. Don't let any such bureaucracy drag you down. Agile development. Design reviews. Collaboration. I can easily justify any and all of my designs and proposed changes. Inspire people to want to do better design / construction. Find those who care and have enthusiasm. Some of us do!
I don't know who you are nor where you are, but you're confusing what the news media says, with what actual American's say and believe. Only SHITHEAD IDIOTS believe the first thing they hear without fact-checking, especially if it comes from the too-often proven liars in the news media.
I'm truly weary of the "looky how cool I am" USA bashers (not accusing you!) but I have to be a bit of one: the problem here (USA) is complicated by lots of competing politics, greed and money control, safety fear by the public, laziness which leads to huge cost overruns (we need more money!) which spooks others who might otherwise have started new nuclear projects. The Three Mile Island incident didn't help, and then there was Chernobyl which really sullied nuclear power for us. It's a mess. We're too competitive, and as such we lack cohesion. I think nuclear can and should be done more, but people have to want to do it, rather than see it as a "cash cow"; a collective cohesive determination.
Yes, I've been super-impressed by all of Europe's (and UK!) investment in and progress toward clean power.
I'm doing my little part to help keep the reactors running safely.
Thanks for the info. I like when people have a good grasp of the big picture and put things in perspective. A huge problem in today's society is partial information, including (maybe especially) by the news media. I think wind and solar are helping, but I trust you that they won't solve all energy needs. I've put in a few PV systems and I know a reasonably sized system makes as much power as a typical house uses, so in my mind if we put PV on houses and shopping centers, we can cover a lot of the need, but big industries will use more than PV can reasonably generate, and skyscrapers might be difficult to achieve anything close to net zero.
I've been a huge proponent of nuclear power for a very long time, but with the provision that 1) it's done well with true safety thought out, and 2) much better design and efficiency. I'm not a nuclear engineer but I've been working on a project that deals with system safety and monitoring and that's all I'll say for now, and that it's cool and I'm proud to help / contribute to better and safer nuclear power.
The guy hiding his Cornell degree probably exfiltrated all of your company's IP and sold it to China.
Smart and dishonest is a dangerous mix.
It was long ago in a galaxy far far away. And the guy hadn't finished the degree. His wife completed her PhD and got a high-paying job far from Cornell and they had a kid. I don't know the whole story, didn't and don't care. He wasn't really being dishonest. It was a somewhat low-paying tech job and the even partial BS would likely have disqualified him. He needed a job, passed the fairly simple quiz, and ended up being an awesome employee for at least 7 years.
And I'm holding back laughter thinking about any kind of IP at that company. But a Japanese company did what the Chins do now- copied one of the products, but I thought that was silly because it was an inefficient design, and the market was small, and they likely lost money on it.
Cool, thank you! And for the record, I don't understand many of people's pursuits and priorities, but I do enjoy the richness of the variety of life, and somehow often find amusement in others' wackiness. Occasionally youtube "people are awesome" is fun.
Nobody said you would. But someone might, for whatever personal reasons, so now they can. There are many ways you can experience life in the 1400s, or 1776, or 2000BC. Some people watch soap operas. Some eat bugs. I don't know why, it's their life and option, right? Live and let live; sound okay? I don't think they're hurting anyone. You could argue that it's wasted effort, but so is art, sports, entertainment in general. Webpages have gotten so terrible that maybe a return to simpler roots is a good thing.
And thanks again. I just did some quick research and calculations and your number of 4x seems right. So they'll take up more space, or you just deal with shorter trips, but faster charging when/where high energy chargers are available. But they'll weigh less, or maybe about the same based on energy storage.
Capacitors will probably cost 4x too, but again, pay for themselves in the long run. And much less of a fire problem, maybe zero.
I gotta do more research and maths.
I have a van I want to electrify. Huge amount of space for capacitor banks...
Thank you so much for the info. Very interesting. A friend of mine has a Bolt and he gets maybe 240 miles on a charge. I'm thinking you could pack more ultracapacitors in here and there, maybe 30-50% more, and still get decent range, and be much better off in the long run when other Bolt owners are facing battery replacement.
I admit I don't know how much longer ultracapacitors would last versus any present battery technology, but my hunch is it would be significant.
Another advantage is the ultracapacitors should be able to take much more charge current without heating up much so can be charged much faster.
I need to post this at top level, but your post inspired this thought: one of the inherent problems with the process (that you're caught up in) is that I'm looking for a full-time job, where I'll likely have weeks or months or on-going work on a project. The typical HR process (tests, interviews, etc.) is a crap-shoot because I might happen to have the knowledge, luck, and work well under the undue pressure of a job interview, but maybe I don't at that time, but maybe I would be the best for the job if someone could evaluate my potential.
Sometimes I can (and do) solve complex problems very quickly and people think I'm a genius, but it all depends on A) the amount of knowledge I have on the topic and can remember when needed for processing, and B) some kind of luck / magic.
Otherwise it involves research, which could take hours, days, weeks, which nobody has during an interview.
And I'm not just philosophizing / theorizing as so many do; this is from direct experience, and observation of very wrong people getting hired and becoming coworkers.
Very flawed process. Wrong people get hired. Square pegs in round holes.
BTW, yes, I've hired people and/or taken part in the decision process. I administered very simple tests. In one notable case I hired the 2 guys who would have failed every current HR checklist item. By HR rules, they were the least qualified for the jobs (one hid his almost complete Cornell BSEE). But they were the only two who got all the test questions right. Both were awesome productive. The other one went to night school for a BSEE and graduated Summa Cum Laude.
My point: HR are generally (I wrote "generally") egotistical control-freaks and should not be allowed to make hiring decisions for technical workers, unless you have actual technical people who also wear HR hats part-time.
Anyone have data on using ultracapacitors in place of batteries? I know they store less energy per volume, but AFAIK they will last much longer, and maybe on a bus or truck where there's more room, it would pay off in the long run?
I'm sorry you're having this loss at such a young age. I'm a good bit older and regularly run (mix) sound (and I'm pretty good at very gentle augmentation of classical, to full-on rock). I haven't had my hearing tested, but I don't perceive it to be any worse than when I was 20, and now that I've gotten into audio work, I ardently/fiercely protect my hearing.
I know they're pricey but you've bypassed the world of junk hearing aids, and some argue that the super-cheap ones can do more damage.
Some tinnitus is mental / neural; some is caused by infection. Hopefully you're seeking very competent medical help / tests?
Sadly my mom suffered from hearing loss (which significantly impacted her life) that might have been lessened or stopped if it had been caught years before. One of the symptoms showed up on a head CT showing some bone loss that was attributed to an inner-ear infection that can spread.
I occasionally get some perceived tinnitus that I attribute to a combination of not enough sleep and too much (or any) caffeine.
Yes, I too tried about a dozen Android sound amplifier apps- all had (IMHO) huge delay and as such were useless. I blame it on Android / hardware processing; I don't know enough about the Android platform to know if the processing delay could be avoided. If the google app has delay, it's useless.
I wanted to try some of the many very inexpensive hearing aids available- some as cheap as $12. Some are rechargeable, and some claim to run for a month on 1 battery.
I'm no doctor nor biologist, but a quick web search: "can 2 sperm fertilize 1 egg?" reveals a YES. So it's possible the twin girls have 2 different fathers. And that would be easy to prove if the mother would divulge the identity of the 2nd father.
My issue: maybe it is a probe sent by gigantic aliens, so it's normal size for them. But as far as we know, C is a universe constant, so they're not going to hear back from the probe for a very long time, assuming they're as far away as they'd likely have to be. Yes, maybe it's off course from a civilization from long long ago far far away.
Or maybe it's just one of the infinite possible formations left over from a supernova which blew away all of its planets, asteroids, etc.
Great points, but not something you can change (the available humans). IE: I take a strong stance that machines and their UI are supposed to serve US, the humans- whoever and whatever they are. I'm sick to death of holding a programmable machine (smartphone, for ex.) that I can't configure to work well for ME, the user.
Personal case in point: for several reasons I struggle with touchscreens- mostly largish fingers. Being an EE I know there are parameters which frustratingly are hard-coded into the circuitry and software which reads the touchscreen. But I, as the users, have NO available settings. At the very least give me some kind of self-learning algorithm. As a result I mostly use a much older early smartphone which has a utility that learns your touch style / technique. But the newer Android, nope.
Designers / manufacturers / builders have gotten too far away from the goal of machine / tech. design: serve the human. And people are literally dying unnecessarily as a result.
Here's an idea: before putting new airliner controls into production, have an amateur / private pilot / average Joe sit in the cockpit simulator and see if they perceive that the autopilot is disengaged. Or that a partial autopilot / compensation system is partially compensating and will eventually kill lots of people. (in case you're not aware, that's what has caused most of the recent airliner disasters.)
My point is: there's no such thing as lots of experience on a brand new thing. Worse yet- you take a familiar thing (cockpit) and change it subtly, but the resulting functionality change has huge implications, and put the same pilots in it.
I'm sorry- it's all part of a pandemic of very bad UI design. I think much of design has moved much too much toward art and gotten away from functionality. I personally love art, but please make my machine work for ME.
64-bit for ARM has very little to do with memory in most cases. It's for the improved AArch64 instruction set.
Yeah, thanks for that. Either I'm confused, or most people are. AFAIK, 64-bit refers to the data word size, NOT address bits. I'm not aware of any CPU with 64 hardware I/O bits of address.
Under routine conditions, the modern airliner can pretty much fly itself. The pilot is there to deal with things that go wrong,. Since you can't possibly predict and program for everything that can go wrong, it's important that the pilot have the final say.
Better that a human be the one who killed us than a machine.
I quite agree. After reading about several recent fatal modern airliner crashes, it seems the problem was caused by the machine overpowering the humans who were unaware of the machine's efforts to compensate / counteract. Or in a few cases, the humans assumed the machine (autopilot) was still in control, when it had been disabled, but indications were subtle. It's too easy to blame the humans for not knowing what was going on. The machine's job is to serve the human and in every case I've read I fault the UI. I'm okay with the machine continuing to monitor and warn in a big way. It stuns me how these things are okayed by FAA and other regulators.

Supposedly, that is also when most teenage pregnancies are initiated.
I wasn't aware of that but it makes perfect sense, esp. remembering childhood / teen years.
Start school later: What's the big deal?
Thanks for reminding me of that- it's been a frequent news topic recently. I know I would have done better in school with an extra hour of sleep. I know I know, "go to bed an hour earlier". Well, it doesn't work no matter how hard I try.
I think we've agreed on a plan!
If you want to keep changing your clocks, go right ahead. The rest of us will stop the nonsense.

I'm much more concerned that you might have one of the many inner-ear infections. They can be very difficult to detect until after they've done much damage. One is "mastoiditis" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4176546/ and
https://www.mayoclinic.org/diseases-conditions/ear-infections/symptoms-causes/syc-20351616. Like too many conditions / diseases, it's often overlooked because it's considered more of a childhood disease; and may well set in during childhood.
