And A&E is free to fire his ass.
Why anybody is complaining about this glorious state of affairs is beyond me.
I'm betting on a lost anchor or random pieces of cast iron from an old ship.
The problem is that while current grade level is forty five feet above the machine, historical grade is twenty feet above the machine... Who'd dig a thirty or forty foot deep hole in a swamp to discard an anchor or piece of cast iron? While this is the lowest point of the tunnel, this isn't the lowest point of the historical grade (relative to the tunnel bore), that's a block or two ahead of where the machine is currently stopped.
And before anyone brings up a surveying or mapping error 'back in the day', remember Seattle wasn't settled until the 1850's, and the maps they're working from date from the 1870's to 1890's. On the scale of a city, surveying and mapping technology was pretty good by then and thus the odds of a couple of hundred foot error in the location of grade or a twenty plus foot error in the height of grade are extraordinarily slim indeed. You'd almost be better off investing in a Lotto ticket than in betting on the existence of such an error.
"Some residents said they believe, or want to believe, that a piece of old Seattle, buried in the pell-mell rush of city-building in the 1800s, when a mucky waterfront wetland was filled in to make room for commerce, could be Berthaâ(TM)s big trouble. That theory is bolstered by the fact that the blocked tunnel section is also in the shallowest portion of the route, with the top of the machine only around 45 feet below street grade."
On the other hand, that theory is diminished (if not demolished) by the fact that The Object is twenty feet *below* the historical grade at that location.
And then NASA changed their management. And the new management dropped "belt and suspenders" "managing for Murphy's law" in favor of "managing for success". And they launched Challenger
You say this as if previous management didn't also have blood on their hands. Apollo 1 saw 3 astronauts burnt alive in their capsule.
Flammable materials, pure Oxygen environment, negative pressure preventing door from opening doesn't really smell like "managing for Murphy's law".
And Apollo 12, which was sent to the Moon despite having been hit by lighting and possibly having damage which could not be detected. And Apollo (IIRC) 15, which had a failed cable assembly in the SPS - and which was allowed to go into Lunar orbit even though the mission rules specified a return to Earth. (There are others, but these are the ones that leap to mind off hand.)
Apollo era NASA was lucky, they kept making bets and rolling snake eyes - and then covered up for decades just how big the risks had been and how close they repeatedly came to disaster.
That's true, but what's even sadder is that those damn O-rings should've never even been there in the first place. The SRBs were meant to be a one piece monolithic design.
No, they were never "meant" to be anything - there is no "absolute" Shuttle design from which the existing one was a departure.
However it was changed into a segmented multi piece O-ring design because pork had to be provided to Morton Thiokol at the insistence of the senator from Utah, who held the purse strings. (Thiokol, being in Utah, cannot ship a large one piece by ocean and could only build segmented ones shipped by rail)
No, they were changed to segmented design because nobody could figure out how to cast *one* motor grain with consistent burn properties (the monolithic grain took so long to cure that it stratified) - and the Shuttle required a matched pair. Nor could the figure out how to prevent the grain from flowing out the nozzle (the weight of the monolithic grain exceeded the strength of the grain material, resulting in the grain creeping under it's own weight). Not to mention the problem of handling a million plus pound motor without damaging it (as little as 3mm flex over the length of the casing could delaminate the grain from the casing and crack the grain).
"We shall redouble our efforts"
I've always wondered... Why didn't he just say quadruple?
Because redouble doesn't mean quadruple.
You'll notice I never said science fiction authors have a good understanding of nature, just a better one than your average artist.
Yes, I noticed. That I pointed out the fallacy in that belief seems to have escaped you in your rush to build a strawman and set it alight.
A triumph of the human spirit, of technology, of ingenuity, sure - but mainly, an overwhelming triumph of project management.
And then NASA changed their management. And the new management dropped "belt and suspenders" "managing for Murphy's law" in favor of "managing for success". And they launched Challenger when the solid-fuel booster O-rings were too cold to seat properly, over the objections of the engineers.
And the space program was put on hold for 2 2/3 years.
I think I should go back to ancient and venerable Slashdot practice and avoid reading TFA. In fact, I'm not so sure about the summaries, either.
And the comments...
Good bye, it's been fun.
What's so wrong with installing linux on a real laptop?
Modern laptops come with remote administration tools built into the chips on the board. (The vendors tout this as a feature, simplifying administration of a large company's workstations. It's easier and cheaper to build it into everything than to be selective, so it's in the machines sold to individuals, too.)
One example: Intel Active Management Technology (AMT) and its standard Intelligent Platform Management Interface (IPMI), the latter standardized in 1998 and supported by "over 200 hardware vendors". This is built into the northbridge (or, in early models, the Ethernet) chip).
Just TRY to get a "modern laptop" (or desktop), using an Intel chipset, without this feature. (I suspect the old Thinkpad is how far back they had to go to avoid it.)
You can't disable it: Dumping the credentials or reverting to factory settings just makes it think it hasn't been configured yet and accept the first connection (ethernet or WiFi, whether powered up or down) claiming to be the new owner's sysadmins.
If the NSA doesn't know how to use this to spy on, or take over, a target computer, they aren't doing their jobs.
Some of the things this can do (from the Wikipedia articles - see them for the footnotes):
Hardware-based AMT features include:
Encrypted, remote communication channel for network traffic between the IT console and Intel AMT.
Ability for a wired PC (physically connected to the network) outside the company's firewall on an open LAN to establish a secure communication tunnel (via AMT) back to the IT console. Examples of an open LAN include a wired laptop at home or at an SMB site that does not have a proxy server.
Remote power up / power down / power cycle through encrypted WOL.
Remote boot, via integrated device electronics redirect (IDE-R).
Console redirection, via serial over LAN (SOL).
Keyboard, video, mouse (KVM) over network.
Hardware-based filters for monitoring packet headers in inbound and outbound network traffic for known threats (based on programmable timers), and for monitoring known / unknown threats based on time-based heuristics. Laptops and desktop PCs have filters to monitor packet headers. Desktop PCs have packet-header filters and time-based filters.
Isolation circuitry (previously and unofficially called "circuit breaker" by Intel) to port-block, rate-limit, or fully isolate a PC that might be compromised or infected.
Agent presence checking, via hardware-based, policy-based programmable timers. A "miss" generates an event; you can specify that the event generate an alert.
Persistent event log, stored in protected memory (not on the hard drive).
Access (preboot) the PC's universal unique identifier (UUID).
Access (preboot) hardware asset information, such as a component's manufacturer and model, which is updated every time the system goes through power-on self-test (POST).
Access (preboot) to third-party data store (TPDS), a protected memory area that software vendors can use, in which to version information,
.DAT files, and other information.
Remote configuration options, including certificate-based zero-touch remote configuration, USB key configuration (light-touch), and manual configuration.
Protected Audio/Video Pathway for playback protection of DRM-protected media.
Additional AMT features in laptop PCs
Laptops with AMT also include wireless technologies:
Support for IEEE 802.11 a/g/n wireless protocols
Cisco-compatible extensions for Voice over WLAN
This just happens to be one I'm familiar with. I don't know whether (or which) other chip makers (such as AMD) have similar "features" built in as well (though I'd be surprised if they didn't, since they want to sell into big companies, too).
Did you know that if you took all the economists in the world and laid them out, end-to-end, they still wouldn't reach a conclusion?
Have you tried looking at the wiki? 1-click installs for all the blobs
Doesn't that violate an Amazon patent?
Indeed, my first thought also was "did Intel put their chip designs under GPL, or what?"
Science fiction is as legitimate a artistic expression as anything else, if not more legitimate because it is generally written by people who have a better understanding of nature than your average artist.
That's the conceit of SF fandom. (Based on cherry-picking the SF writers they use as their examples.) In reality, SF writers come from all over the spectrum, though the most successful are generally those who do have a better understanding or at least can simulate it to the low fidelity required by SF fandom.
