IIRC Ozalid's were on blue prints, i.e. blue ink on paper by some mysterious trademarked process. They were copies. The "Vellums" were industrial film (not medieval calfskin, as the term originally meant T_T). They were the holy "Alpha" drawing copies, and parts weren't built directly from them as a rule - the stuff was pretty costly, and there were a lot of parts to draw. Losing a fuselage skin could have been argued as a bit more expensive, though, but I'm not entirely sure - the weight of the drawings were said to exceed the weight of the 747.
Correct. And then we're also talking about information that can't be recovered by decompiling binaries, so the point is moot.
Once you're done debugging, you don't need the symbol tables any more, yes? We may need the comfort of rich commentary and maintainability, but the system really only needs the instructions, opcodes, addresses, literals and data in the binary code to work. [Decompiled|Disassembled] stripped binaries are very hard to make sense of.
In the olden days, we obscured code by renaming variable and constant names with some variation of "I"'s and "1"'s and "O"'s and "0"'s. Not as effective as adding the "strip symbol table" switch to the compiles, but far more fun, which mattered then. "O000O01I = o0oo0OI1" and variations were good for inducing headache. We took DRM into our own hands in those days.
Ahh, to be a sadistic, bastard developer again. I miss that.
I think they're just covering both sides of any potential controversy over the use of "assembly" and "compilation" that might be initiated by - oh I don't know, bastards like us slashssons and slashdottirs perhaps.
Wait... Australia has STATES? We must be WAY behind in getting those stars on the flag
Yep, we've earned our stripes too.
By the way, we've bought the rights to the Star Spangled Banner. RIAA agents on their way to your ball games this very moment.
Some Yank owns the rights to Waltzing Mathilda, so it's only fair. RIAA might want to come to our barbecues, as we might sing it in a highly public way after a few beers. But they're nothing you can't fix with a backhoe, drunk or sober.
Bullshit. The second fastest car I owned was a 1974 Pontiac LeMans with a 350 cubic inch engine, four barrel carburator, and dual exhaust (the fastest I owned was a 1968 Mustang with a Clevelend engine)...
It is unfortunate that GMs design errors stained the diesel in the US market for such a long time.

The dot-com boom was characterised by B2C web sites with serious quality problems being rushed into production to gain early market share. The dot-bust came when people became dissatisfied with the quality of delivery (supply chains being the biggest lesson).
Moral? Rushing crap to market won't earn you the adulation of your customers. This goes for Oldsmobile, Microsoft, D-Store.com, and anywhere you have an informed market with an IQ above room temperature. There may be a sort of front-end loading to Sturgeon's Law in effect here.
Very interesting. Given the tight tolerances required, seems like humidity, temperature and just general handling could potentially affect the media, no? What media was used, just heavy bond or some type of stable sepia, etc.?
There were two types of media for blueprints at the place of this example. Ozalid process on large paper for the big'uns, but the little stringers were quite small and fit on a 8-1/2x11 sheet. These were printed on Xerox sourced paper (I think ordinary 18gsm or the like) on a Xerox 1824 or 1840 (I think it may have been) microfilm aperture card printer. These frequently caught fire, and were sometimes jokingly refered to as "brownprints" from the occasional char marks.
Does the error sound a bit more feasible now? (grin).
Forgive my skepticism, but assuming your basic story is true, this can't be the explanation for it.
This was the late 60's, and that was the explanation given for the stringer manufacturing failure of airframe R99997. The problem arose when parts builders took the shortcut of actually using the drawing, not the actual measurement, to build the part. It may be the first thing you learn never to do now but perhaps incidents that happened then are why we have such rules today, no? This was the first commercial aircraft of that size; such precision over such vast structures was not quite such a common ask. Before that, building to a 1:1 blueprint rather than the written dimensions may not have been considered such a heinous crime. I was only a kid at the time, I just filed blueprints and listened to people, but I was there.
This is also one of the few hobbies where it's actually practical to build the high-end technology you need yourself. Yes, you can buy top end gear both new and used, but amateur radio is mainly analog, macro-scale, accessible stuff and you can build basically anything you need from the ground up, or with the acquisition of a few cheap time-savers such as you can find at your local electronic parts supply store (and these places do still exist).
The one essential component you need is a good, fat ARRL (Amateur Radio Relay League) handbook. These are to RF technology what the old postwar Boy Scout Handbooks were to practical survival. Get one, and don't lend it out.
Do you seriously expect facebook to go through the law books on every national and local level and state which laws, where, they are in compliance with, AND keep up-to-date on them?

Reminds me of the old joke:
GIVEN: The entire body of current mathematical thought;
I worked for Northrop many decades ago when the Boeing 747 was first being built. Northrop made these body sections for Boeing. These were in the days of actual blueprints on paper, although they had advanced to microfilm aperture cards to print from by that point;)
The skins had little angled stringers attached to the inside surface, painted with some horrible green mixture. The draftsman who drew them used the wrong width pen, and these stringers turned out to be 1/2mm shorter than they needed to be. Not a real problem you'd think, but there were thousand of them running lengthwise across the skin.
By the time the stringer had reached the cargo door (65BO1859 - god how some things stick in your head) they were about half a meter short. This had a major structural impact on the airframe, so they had to go (literally) back to the drawing board to solve the problem.
Subtle business, building your average jumbo jetliner.
Of course there are contracts, and they are legally enforceable. But once you hit the courts, you lose. All contracts are fundamentally based on trust. Lose that trust and there's no way to put the worms back in the can. Win at court, you could still lose at business.
Also, HF is something individuals can do between each other, point to point, on their own resources and initiative. Internet, outside of a few specialty wifi kludges, pretty much makes you an appendage of $LOCAL_MONOPOLY_TELCO. This can be an issue if they go down, or start doing things you don't fancy...
Being a person who uses, appreciates but fundamentally doesn't trust the government - certainly not to choose how I ultimately wish to carry out my life, I find it useful to stash a few things that help me get in touch with people without the government or government-backed communications media. In my case this includes a few coils of wire, a few tools and an ARRL handbook.
And I keep a few good reference texts in hardbound, in case the Wikipedia volunteer editorial board decides all the articles should be thrown out for insufficient references.
My point is that no matter what happens to a country, the survivors should be able to fend for themselves in an emergency. That means grouping up, and that requires communications. Digital systems are far more powerful and more effective, but you can communicate with a spark gap if you have to if the civil infrastructure goes pfft. I find it's easier to trust people when you don't really have to.

What's fascinating is just how complex the electrical structure of the moon is. Could be a nightmare environment for electronics, no?

What about the dust you'll kick up driving a rover past the array?
You might kick some up, but unless the stuff is given a decent ballistic velocity it won't go anywhere. Can't exactly hang around in the air, right?
On the plus side, every flat surface has the potential to be an etch-a-sketch. Endless entertainment.

Trust your admin, or replace them.
Amen. But on the other hand, some form of independent audit by someone not related to the PFY would be a good add, too.
On the gripping hand, you can't always trust your management, either. A payroll manager without external oversight can sink a company quite effectively as well.
It isn't exactly distrust, it's ... (checks his Spin Dictionary(tm)) ... giving employees extra surety in matters of probity. Yep, that's what it is.
