NASA boss insists US returning to the Moon after Peanuts to show for past four decades

classic "schmuck bait"

really, all of the jerking around and moving targets of the past (with respect to NASA and the moon) were nothing less that "schmuck bait". Question is, who's the "schmuck"? I think it was the voters...

A lot of talk happened right around the time "Apollo 13" the movie was released. Then it died off. Again.

The REAL problem is that only GUMMINTS are talking about it. Gummints involve politics, "other people's money", and (too often) voter manipulation.

It's hard to find a better analogy that doesn't involve a totally cynical look at political leaders, like maybe "The Deacon of the 'Deez" in Waterworld, who gave a speech and showed the tattoo'd back of the kidnapped girl in order to inspire the minions, and got them all rowing ["They'll row for a bleeding month"] even though the Deacon had no clue as to where to go. [IRL example, Jerry "2nd time around" Brown]

If we stopped spending money on social programs, and bought MOON ROCKETS instead, the rocket makers would hire the people who WERE getting freebies from gummint, and they'd be working to get their money [and would probably have a LOT more of it to spend]. And we'd have MOON ROCKETS to show for it. you get what you pay for.

So now I need to come up with an analogy for a) manipulating voters into FEELING that gummint giveaway programs are a good idea, b) dangling "back to the moon" to a group of voters to get THEM to vote for you, too, and c) tossing the idea of going back to the moon, CUTTING the NASA budget, and then SPENDING EVEN MORE on worthless "social programs" to buy even MORE votes.

And Lucy with the football seems close enough for me. "Schmuck bait". And the VOTERS are the 'schmucks'.

Re: "6502 CPU and two 6522 processors"

" But it was never a processor."

well, there was a documented way of sending code to the on-board 6502 for things like "fast disk". but since the RAM was limited, you couldn't load very much. Seriously, though, it was doing what microcontrollers often do, in this case moving the diskette drive heads and whatnot. The ROM was decoded and documented in various books and whatnot. I don't have any of those any more [gave them all away along with the hardware, long ago] and I'm pretty sure that whoever ultimately ended up with it all probably didn't appreciate the geek factor of it...

In any case, it was possible to use the on-board 6502 as an actual 'processor'. It was just somewhat difficult and impractical for anything NOT disk related.

Re: Bang!

interesting. That might explain why my 1541's lasted quite a while, even though on one of them [the first one I bought] I had to cut open the case a bit and place a cooling fan on top because it overheated early in its life. I noticed that Commodore went with external power supplies for later models, which prevents the overheating.

RH dealing with the devil (Micro-shaft)

I don't really blame RH for wanting to "partner" with Micro-shaft with cloud services (etc.) but I strongly suspect they might end up being swallowed later on...

(history suggests this pattern)

As for IBM, they've been committed to using Linux for quite a while now, so I'm pretty sure they'll be happy to make hardware that Linux runs on (and software solutions that run on them). No danger to RH there, as far as I would guess.

But RH needs to make sure they have an 'ass protector' already installed (and properly configured to defend against Micro-shaft). They're sneaky little buggers and RH doesn't need a "surprise".

Re: .dot not a lot

"they're too lazy take it out"

In DevStudio 2010 you have to go through and "un-check" a bunch of things (for an MFC C++ application, anyway) but [unfortunately] you STILL need a damned 'manifest' to avoid your application NOT being compatible or being treated with UAE when you don't want it to. At least, from DevStudio 2010. I don't like any of the later DevStudios as they're all oriented towards that 'UWP' crap and have 2D FLATSO user interfaces. 2010 is the LAST DevStudio I'll evar use, probably. And I'll target Win 7 if I ever have to write another winders application.

But yeah, if you jump through the hoops [there are a finite number] and turn OFF all of that "shared MFC" and "shared runtime" and "framework" and other CRAP, you can produce something that only has the windows API as a dependency. That's right, JUST AN EXECUTABLE! Amazing concept, huh?

[who needs all of those DLL HELL libraries anyway, just static link and be done with it - it'll load faster, too]

Welcome to the 21st century, where pretty much EVERY computer nowadays has GIGABYTES of RAM, and TERABYTES of hard drive storage, and if you pack around 256kbytes of "what COULD be shared libs" in every application, it's a drop in a bucket [and probably will load/run faster too].

ok someone will ask: how can it RUN FASTER? Well, if you do static link optimization tricks, you can get functions that "call each other" to be located within the same block(s) of memory, which helps to make L# cache more efficient, with a smaller code footprint in the cache, and more likely to get various CPU-driven optimizations to happen, yotta yotta. And of course, LESS PAGING ACTIVITY when the system demand is high. And did I mention it would LOAD FASTER?

Re: MS Tax

ack - there are several manufacturers who build computers without pre-installing windows. Sometimes the linux-capable versions cost MORE, though.

and there are also the 'netbook' variety computers, if all you want is something with a screen and keyboard and USB for mouse [and maybe a simple touch pad] for "el cheap".

So yeah Linux is out there, but doesn't have the marketing capital being shoved at it like MS does for windows. Also Wine is pretty much "not good enough, still" to run any windows application, so people with legacy applications [or those that REQUIRE windows, shame on you devs who STILL do that] will end up paying the MS Tax, and getting stuck with "the boar that has lipstick on the non-oinky end" known as Win-10-nic.

If I had the capital, I'd complete a cross-platform toolkit that would allow developers to create both C and C++ applications that are truly cross-platform, using a reasonably low-level API [so as NOT to have a boatload of shared libraries that it depends upon]. But as it's me funding myself doing the work, I still have to pay bills and so can't devote sufficient time to get it all done fast enough. Dammit.

Re: I've outlined the reasons on El Reg countless times

" Insiders = nincompoops. Fanboys, not professional QA testers."

Yes, Micro-shaft definitely made it VERY UNFRIENDLY for *ANYONE* who became an insider in order to improve the product by feeding opinions back to Micro-shaft, when such feedback did NOT fall in LOCK STEP with the FASCIST REGIME opinions of Micro-shaft.

Dissension was rewarded with BANS and DELIBERATE+OBVIOUS BIASED TREATMENT of so-called "term of use" violations. Fanboi trolls would deliberately engage people, "a comment" that didn't even violate TOU would be issued from the target, and then *POUNCE* and BAN. They got REALLY BAD after a while, like they were DELIBERATELY trying to clean out EVERYONE who dissented, so they could have a nice "pleasant" forum of like-minded sycophantic groupies.

One day 4 or 5 individuals commented to me in their forum about things that were irrelevant, but it was like 'sock puppet' posts, people who were CONSTANT violators of the TOU (they were frequent ad hominem attackers, for one). Next thing I get is a 'ban warning' (a "last warning" in fact) for allegedly doing something NOT COVERED by their TOU. At that point I abandoned their forum to their own folly. It was obviously NOT going to help any more to tell Micro-shaft why they were screwing up, with examples and specificity, in as many areas as I could think of [which I did for about a year, actually, and did NOT violate their TOU]. So yeah I saw it first hand. They didn't want dissenting opinions. Many other dissenters left the forum at the same time.

Re: Down Range

"If downrange is the sea, then it doesn't matter"

Well, even _I_ wouldn't go THAT far, to say "it doesn't matter". But "the solution to pollution is dilution" more often than not.

The sea is 'full' of a lot of materials, in extremely low concentrations. However, I don't really want to increase the amount of radioactivity in it, if at all possible.

When nuclear ships (U.S. Navy, anyway) need to discharge reactor coolant, they filter it first (there are a LOT of reasons why this must happen). And they hang onto it (in a storage tank) until they get back to port, if possible, where it will be appropriately processed. But occasionally they may need to discharge coolant into the ocean [and then they keep a log of how much, etc.]. As a general rule, it's "not that radioactive" but they still have procedures to avoid doing so when possible [and this was back in the 80's, so maybe they're even more careful now?]

Re: Down Range

"Any more dangerous than the radioisotope generators we've hurled into space already?"

probably not, just more radioactive material in them. In fact, based on the 'hotness' of a typical radioactive thermal generator, it might be (short term) environmentally WORSE than a much larger amount of uranium.

Now, if a spacecraft with one of these was returning to earth, let's have them ditch the thing towards the sun before they get into earth orbit. I wouldn't want a 'burn up on re-entry' disaster to release FISSION PRODUCTS, which are a whole lot WORSE than Uranium fuel.

Re: So basically....

"dynamically allocate current from different resources."

yes, including batteries, super-capacitors, flywheels, and other 'power storage' means, to absorb the surges while the individual power plants adjust themselves to the changes in demand.

You could even use a hydro-electric method that pumps water into a large storage area to absorb excess power, and then uses it to generate power when demand exceeds capacity. Just a thought at the moment. Its like the epitome of the whole concept.

I am pretty sure that "the power grid" (and the people running it) already uses fossil-burning plants and hydro-electric plants to handle demand changes (at least in the USA), while allowing nuke plants and solar/wind systems to run at full capacity as much as they can, then brings on 'peaker' plants to handle peak demands (gas turbines, diesel) when necessary. That assumes that GUMMINT didn't enviro-regulate everything to the point where no peaker plants were built... [so say hello to 'rolling blackouts' when it's cloudy and hot and humid and wind speed is low due to some kind of tropical depression, or whatever].

Re: So basically....

"am I misunderstanding how they work"

No, you're right. Heat rejection is a big problem for the moon. I don't know how deep you'd have to dig for a "lunathermal" solution, either. On earth it might be 20 feet or so, depending [then you just put a bunch of water piping undeground to reject heat into the earth]. On the moon you could do the same thing, but it's not very 'portable'.

I assume that the ginormous circular reflector is for that purpose. NASA knows how to make this work, as they did it on the space shuttle. But it's worth pointing out that any heat engine (including the Stirling engine) needs a differential temperature to work. So does a peltiere device, which is what I originally thought they'd use. But peltier devices aren't as efficient and would probably weigh more for kilowatt capable power.

I would also expect inverters and batteries to manage short-term transients. I can't see speed control on a Stirling engine being all that easy. If differential temperature drives it, then that's also what controls it [and you can't heat/cool things fast enough for speed control to work really well]. So they'd probably use 'load control' to also control speed, and use batteries as a 'surge' to keep speed within a safe band [with some safeties to burn off power or 'put on the brakes' when necessary].

In other words, controlling a Stirling engine generator could be like balancing a pole on your nose. Then again it might have some natural speed control built in, due to fluid friction and/or momentum, with that back/forth fluid motion thing going on.

It's a fair bet that the stirling engine + nuke plant would respond poorly to rapid transients, though. But the U.S. Navy solved this a long time ago in their own power polants, since you can go from "all stop" to "all ahead balls to the walls" in a reasonably short time on THOSE systems. Even so, electric power generation transients are usually a LOT slower than "flooring it" on a propulsion system. So maybe it's not an issue?

bombastic bob Silver badge

Re: So basically....

It's the "Son of SL-1"

There are (unfortunately) a couple of significant similarities...

a) small, low power reactor that's portable

b) a single control rod can make it go critical

If there is a way of doing a safety shutdown that does not involve "that one control rod" it would certainly be a LOT safer This is because the fission products in a fission reactor are often "physically bigger" than the original material. Reason: higher density for uranium, lower density for "what it splits into". basic physics.

Basically, the fission process causes 'fuel swelling' as the fuel is burned off. This could cause 'blistering' and/or 'swelling' of the fuel material to an extent that it impedes control rod motion, depending on the design.

And that "single control rod" can EASILY get stuck as the fuel changes its shape over its lifetime. This means you lose control of the reactor. Oops.

To compensate for this, designers need to make sure that you have rod channels that resist the effects of swelling and blistering, as well as having "some other means" to shut the thing down.

NASA needs to work with the U.S. Navy on this (if they aren't already), as well as General Electric and Westinghouse and other military contractors that know how to build small reactors for submarines.

For a bunch of reasons, the reactor core needs to be very compact, as compact as possible. This not only reduces the fuel loading, but it improves the temperature coefficient. Small reactors tend to have negative temperature coefficients, which means that as temperature goes up, reactor power goes down. this makes it stable. Very large reactors tend to have positive temperature coefficients, which means you can't change power levels very fast, and have to constantly monitor it and tweek it to keep power levels stable, because an increase in temperature makes power go UP [in a transistor they call this 'thermal runaway']. Large reactors, however, can have a much larger fuel load so (in theory) you could go longer without refueling. Additionally, a large reactor could be fueled with 'fuel pellets' inside of a permanent tube structure, rather than alloyed fuel material that has to be completely changed out, making the refueling process a lot simpler.

So large reactors have their advantages. they're just WAY harder to control.

In this case the small reactor would be perfect. Down side, it would very likely have 'alloyed' fuel, meaning that it would be subject to swelling and blistering that could cause the single central control rod to stick, resulting in a potentially uncontrollable reaction. The end result could be a partial meltdown, but probably would just overheat everything and damage it beyond repair. Or, it might just slowly drop in temperature until it shuts itself down. There's no telling. Any of these are possible for a number of non-obvious reasons, caused by changes in power demand [among other things], and despite the highly negative temperature coefficient, it's still possible [following a large power transient] for a stuck rod to cause power levels to go unstable and either melt it down right away. or temporarily shut it down and make it go into a 'cyclic' uncontrolled shutdown/restart mode that results in an unrecoverable power transient that completely destroys the thing. Not 'boom', just melt.

So, yeah. That single control rod is a big concern.

Re: What if ...

form an LLC. it means paying extra money, though, and filing separate tax returns, setting up a payroll service, yotta yotta yotta. _I_ think it's worth doing, because it puts you more in control and has other benefits.

Re: Work Choices

"for a period in the 80s and early 90s it was a lot more lucrative for both employer and employee for the programmer to be paid as a contractor but that extra loot came at the expense of the taxman."

YOU, sir, deserve a BEER!

This is NOTHING MORE than a clamp-down on contractors (in general), Gummint just wants our money. I'm glad you DARED to say it!

Re: About damn time

*NO*. Just *NO*.

I do _NOT_ want gummint limiting my ability to be a direct contractor for any individual or organization. This is just a (yet another) POWER GRAB to force employers to pay into "the system" with payroll taxes, etc.. Just like the earlier rulings that said a contractor can claim unemployment insurance MEANT THAT _I_ HAD TO START PAYING INTO A SYSTEM THAT WILL NEVER GET BACK TO ME. Since I own the corporation, and contract through the corporation, the rules are (for now) a bit different, but GOD DAMN them, because you KNOW that people like *ME* are on their targeting radar, too... [for more money to be extracted, more regulations to be imposed, etc.].

Even though i'd fail the current ABC test for being "an employee" because a) I do work at home on my own gear, and b) even if I'm on site, it's through a corporation of which I'm an employee. Fortunately I can still choose how much to pay myself with 'wages" and how much "with other things" and things like computer hardware, software, online services, etc. are all business expenses [so they are off the top of revenue, BEFORE being taxed], though it's a wash when you consider all of the OTHER taxes that I have to pay (including that UNEMPLOYMENT INSURANCE that I will never be able to claim - 'FUTA" - I have 'grade F' and the rate is one of the highjest, for some reason - *A* *TOTAL* *RIPOFF*).

It also makes me wonder about the job-shopping temp agencies. How will this affect THEM???

Re: Sadly

"The unwanted ( by pretty much everyone) 3d crap is still there"

proving that, to Micro-shaft, '3D' meant something COMPLETELY DIFFERENT.

When _I_ say '3D' I mean an XP-like or Windows 7-like interface (not "the Metro" 2D FLATSO with shading like lipstick on the non-oinky end of the boar).

Micro-shaft missed the boat on that one. Easy to do when you've already jumped the shark and fallen off of the cliff...

"once you've navigated through a maze circle jerk of help options, none of which quite address the problem you are having."

fixed it. you're welcome. sometimes a local 'grep' gets you the answer faster than being jerked about by link-hell.

Re: "have mobile Internet on their phone for when the PC is broken"

"There are still some situations" [snip] " and you would still like to have help available"

I've already tried these kinds of "cloud based only help" things before [read: DevStudio after 2010] and NEVAR want this kind of ABOMINATION *EVAR* *AGAIN*!!!

I don't need internet bandwidth choke points (or service outages) to get in the way of me doing work. wasting spending time commenting on El Reg takes up too much of my time already...
