  1. Why doesn't th eUS and the EU simply ban anything made of plastic, and make it a capital crime to be caught using it?

    THis will without doubt, fuolly and certainly cure thed problem. Plastics will disappear from th eoceans overnight, never to plague thte world again.....

    Oh...hold on..... No it won't. Because the EU isn't the problem, and the USA isn't the problem.

    This won't remotely put a dent in the problem. Because the countries that are the problem don't give a damn other than being really happy that other countries are being blamed for what they are doing.

    Virtue signalling that accomplishes nothing. Billy said it best: it is a tale told by an idiot, full of sound and fury, Signifying nothing.

  2. I just remember the old hot rods with oversized engines that they had to cut out the hood, to fit the engine block, often removing the exhaust system, so out of the engine we seem combusted flames going out the sides. We just need phones with exposed heat sinks for added effect we can put a spot that you fill with water to watch steam expelling from it, or a closed pipe system with clear tubes so we can see colored fluid moving about, like on the old Cray super computers.

    Well played! I like the idea!

  3. Unfortunately USB phone charging and battery charging for RC are rather different problems.

    With USB you have to pretend to be lots of different types of charger and implement current limiting, and the adjustments you make are not very fine gained. The actual battery charging is handled by the phone, all you can do is supply 5V at a certain max current.

    Direct battery charging is actually easier in many ways, just a constant current circuit with digital adjustment and some monitoring. One of the nice things about Lipo is that it's really easy to charge, compared to say NiMH.

    I have a battery charger that is designed to charge LiFe, LiPo, Lead Acid, NiCad and NiMH. It has a lot of different cables to attach to various devices, and is programmable for different charge currents and rates and of course types. It's pretty cool, but the big trick is making certain you program it to the right type of battery. I definitely could make a real mess if I don't program it correctly.

    I do charge my battery packs at about half the current that I could.

  5. life of the battery won't matter when the whole thing will blow up the fifth time you use it, and take your house or car or office with.

    I recently made a safety video for an RC plane club. There are two main catastrophic failure modes. The first is shock damage. This is mostly a lot of smoke. Not much fun, but you'll probably not be harmed - well badly harmed depending where you are and where the battery is

    The second is drastic overcharging. This is the one that makes a lot of fire. I saw a demo of a RC 3S 11.1 Volt LiPo being charged as if it was a lead acid battery, and charged as if was a 20 something volt version. Holy crap! But hey, Lithium itself is almost unstable all by itself, and the electrolytes are flammable. Overcharging can create metallic lithium from the anode material, and then the nasty stuff happens.

    And while we would think that this is a rare thing, its surprising how many people just hook things up and walk away. Don't. If I were foolish enough to use this charger, I'd have a supply of at least sand ready, or better, a class D extinguisher.

  6. I keep some slow chargers around for overnight use, to preserve the battery.

    Smart move. A LiPo can last a surprising long time when not abused.

    I was thinking about an open source project to build a smart charger that linked to the phone via Bluetooth or over the USB cable. The phone would be able to control the charge rate, and an app would offer features like adjusting charging speed based on the time and only charging to 80%.

    I know some RC airplane enthusiasts that would go for an outboard version of that.

I don't know how anyone who works for Facebook can live with themselves knowing that the world would be better off without them doing their job.

    What is really needed badly is since Facebook considers that knowing users and even non-users every online activit is their right, the time is right for poisoning the tracks.

  11. "Unless we plan on many launches to assemble a lunar-going vehicle in orbit"

    I didn't realize that 2-3 qualified as "many". A falcon Heavy can loft the equivalent LEO payload of a block 1 SLS in 2 flights in expendable mode and 3 flights in reusable mode and for FAR cheaper. The only issue is assembling the parts in orbit, but we've been doing that since Apollo so I doubt it would really be an issue.

    Funny how random guys on Slashdot are knowledgable about so much.

    I guess we'll run down to Home Depot and pick the parts up tonight, and after three Falcon heavy launches, we should have everything ready to go to the moonn in a week if we don't stress ourselves. PLanning is for loosers anyhow. Just Do it. I'll get hold of Elon and have him deliver the heavys the afternoon. You're in charge AC - Suit up, and get the hell into orbit. Mike Pence depends on you, so GodSpeed, and Boldness, and do not under any circumstances miss a deadline. If things aren't ready, we're going to launch you anyhow. Thoughts and prayers!

  12. Just like SLS's impressive track record reliable on-time launches. While SLS is further along in it's development, BFR is proceeding at a far faster pace

    Weak howaboutism. While you wrap yourself around the axle, spoiling for a fight over the rocket used, at present, are you claiming that we can send people to teh moon with available rockets by Election day 2020?

    This is the point. We can't do it as we are now equipped. Whether it is the communist inpired and corrupt SLS, or the blessed by God and hand of the free market proof of concept Big Fucking Rocket. We have neither, and you guys are missing the point.

    Anyhow, what is the commercially made landing craft that will land us on the moon in a little over a year? It must exist in order to land us and return us.

    Can't use something by NASA - Or Boeing. The clock is ticking, So I'm certain these things are launch ready.

  13. Bfr can get 220,000 pounds to leo. Saturn V could do 260,000 pounds. You can launch more than 10 bfrs for the cost of a single sls launch. Do the math.

    I have to admit, the BFR has a long established track record with not one single problem. Perfection - the most reliable rocket ever.

    Funny how someone who signs the praises of a never flown rocket attempts to tell me to do the math.

    But ate least you were wise enough to post as AC.

  14. All of this is an attempt to save face looking at the various tangible Moon projects from China and others. I'll believe it when NASA says "we'll go to the Moon in 20xx" and xx<25.

    They already did that and succeeding administrations changed the priorities. I'll believe NASA is going for a moon landing when they actually touch down. Then they can get busy building a wall to keep people from the Mexican part of the moon from invading their crater with 'caravans'.

    When the Chinese land ans start establishing their systems on the moon, the same politicians who stood in the way of NASA at every turn will shit their pants and scream about how NASA dropped the ball and allowed the Chinese to achieve space superiority. Then we'll act. Worked for Sputnik and the Russian BM systems being developed.

  15. Setting bold goals and staying on schedule.

    So I guess, they sacrifice safety.

    Well, both of those are hard to do when every President sets a different goal for NASA.

    BAM! we have the winner here.

    Yup, Even with 8 years in office as has been the trend lately, NASA's goals and budget have been changed willy nilly by each occupant. NASA is just a political football, I'm amazed they function as well as they do.

  16. No, what they sacrifice is _money._ And the current presidential budget proposal does not match Pence's words.

    And how! So we're going to mount an ambitious moon program based on Falcon 9 Heavy? And send people to the moon this year?.

    One major fucking sigh.......

    Unless we plan on many launches to assemble a lunar-going vehicle in orbit, and somehow do it in a little over a year, it is pretty amazing to think we're going to do it with the present stable of rockets.

    As I've noted somewhere in the deep dark past, each of the different rockets in production have their niches. And if we are planning to go to the moon, we really need a Saturn 5 level of rocket. And while we can quibble about the details like solid boosters, that rocket would be the SLS. Which the present administration is trying to kill. The only way present commercial rockets will be able to handle this is a ISS style construction in orbit model, ferrying parts to orbit.

    Really, what Pence is trying to do is ignite an Apollo type program while providing precious little support. Apollo was balls to the wall no holds barred, along with a budget to match. Pence's new policies and bold mindset will accomplish nothing without a blank check.

    The answer they always give is that, "We can't predict them

    Actually, we can predict exactly where the new jobs will be.

    Grocery stores spend 14% of their sales on labor, and those with self-checkout have reduced their labor costs by 25%, or 3.5% of sales.

    Since the grocery business is very competitive, much of those savings has gone into lower food price inflation. The rest has gone into dividends for shareholders. Either way, that extra money goes into someone's pocket.

    What do they spend that extra money on? That is where the new jobs are.

    Not where, but what employment? Your concept of the Job Creators and Trickle Down Theory as the driving engine of more jobs being created than destroyed is interesting.

    My last 35 plus years in the workforce has shown me that the employee is considered the enemy, a parasite that is stealing money from the pockets of the stockholders. Supervisors can make extra money by eliminating employees. One I worked for for a short time bragged about it.

    This isn't trying to make money by inventing new gewgaws using the newfangled industrial machines, this is a direct attempt to eliminate labor.

    This automation is inevitable, but if we head into it without understanding that once the goal of eliminating humans from the work pool succeeds, we better either have a massive depopulation program, or perhaps use the permanently unemployed in a latter day Hunger games scenario and let them kill each other off for our entertainment. Otherwise, the poor will continue stealing money from the pockets of the stockholders.

No more having to think, well it's 5:00pm here in California right now, so that's -7GMT (standard time zone rules apply, -8GMT a month ago), Tokyo is +9GMT, so that means Tokyo is 16 hours ahead. 5:00pm is really 17:00; and 17:00 + 16 hours = 33:00; 33:00 is tomorrow; so subtract 24:00 to get 9:00. So it's 9:00am tomorrow in Tokyo, so yes they probably just opened there because I know they open around 8:00am Tokyo time.

    Time zones make sense as you don't want my clock to be 5 minutes different than your time but the time itself should be set based on some concept of sunrise, sunset, or high noon. What you are really asking is "what time of day is it in X?" or even "will so-in-so be awake / at work?" If we just set people's timezone where 7am is always the approximate time of sunrise then this would answer this question fine and businesses can set schedules appropriately. Many businesses already have summer and winter hours so daylight savings time does nothing but complicates the communication.

    So if I want to know what time it is in Australia, all I have to do is call someone there and ask if the sun is up.

    And Why don't you check with the higher latitudes and tell them that 7 A.M. is their average sunrise? Or is your world one where you only do business with peopel 100 miles away or less? Has Slashdot gone over to the flat earthers?

    Was that a mistake though or was it the market doing allocation efficiency. Arguably it was focusing resources on those who were most productive. It just happens to suck if that isn't you.

    There have been some really interesting times after large numbers of humans were put out of work. Some of them gave rise to very scary times, and even in the 1940's, a brief blip in the world's population.

    1. All automation in the past was GOOD.

    For us now but not for the people at the time. Go and read some Dickens. Life sucked very hard for a lot of people.

    There is an example of that in many small towns in the USA. Middle aged people of a limited skill set have lost their jobs, typically in things like clothing factories for the ladies, and the mines for men. The factories and the mines close, the mines especially become more automated. So you have people in their 50's with approximately 0 chance of being hired, between their skillset and age.

    If they move to find work, it will be minimum wage work, but they are still not likely to find any.
