We're gone

We're done and gone.

Belaboring the obvious loses its appeal, after awhile. So, we'll bid goodbye to Here we go, again and 2010. Not that some comment might not appear, now and then, particular to that subject (actually, probably more in praise than not).

There are many other themes to follow, such as how concerns about proofs lead to testing. But, that discussion has more of a focus on the cyber than on the physical. For real things, we have a shake out period (ought to), yet even during a long production run, there needs to be sampling to see if the process has not gone awry.

Other themes:
  • What is the 'truth' behind business?
  • Did King Alan really let off-the-books operations become the vogue despite the smell?
  • Business cannot be all wrong (even with that pervasive notion of jungle as the metaphor). Can the effects of this notion be enumerated?

07/15/2013 -- A fire late last week bring an opportunity to see what goes into determining whether to do composite repair or to undergo a section replacement.

04/07/2012 -- Flightblogger ends, as least, Jon's watch. Some issues raised five years ago are still apropos. The context may have changed a little, yet, perhaps now is time to re-address the themes which are beyond aviation, only one of a whole bunch of domains.

05/28/2011 -- Lemons problem, dark pools, ... Oh, so much to look at!

04/19/2011 -- Still gone.

02/03/2011 -- This is a place holder, for now, for Lewis' article. The Irish people (where is the rage?) were screwed over even more than the Americans. Now, one could argue oops; but, the truth is that certain minds need much more restraint than they are willing to admit. Unfortunately, other people bear the effects of these idiots (who, by the way, may, in many cases, test well - too bad there is not an effective arse test).

01/06/2011 -- I'm not back, but I have to make some comment on the fact that Jim M was in the group of those who have the gall to tell us, via our representatives, what we ought to do for them. Sheesh. I'll quit, now, before I start to re-look at the faults with this camp of people. Who is perfect? Well, a lot of us do not go about making unreasonable demands upon those who are providing a big part of our paycheck (yes, the taxpayers).

01/01/2011 -- We have four last posts of December under our belt.

01/01/2011 -- When one introduces a sensor in a control sense, that piece of information becomes part of what makes a system work. That is, even if the information is only sampled, it is not ignored.

Here we go again, III

The lessons that can be learned from 2010 are many and wide. As one would expect, the list from 2008 seemed to mostly be about finance (and fiction). Now, we can broaden the view.

Just now, I was looking at some Wikipedia pages on biochemistry, in particular on chirality (note the uses). We would see this as handedness. Well, it seemed that it might be fun to use an analog of optical resolution as an overlay while looking at project (program) management problems. After all, has not this blog berated mis-use of mathematics (Effectiveness, Abstraction, and Computational)? As well, has not the concept of underdetermined come to fore, now and again? But, a new wrinkle, brought on by computation is visualization and the whole notion that some ephemeral digital state is similar enough to the natural (God made?) state to which (or for which) it's being proposed as equivalent (only in certain types of world views) for us to make decisions that are sound.

A white paper asked: Do Sensors "Outresolve" Lenses? Just how does (can) this be applied?

Well, some comments to blogs, such as to the flightblogger, suggest that the 787 program assumed too much of something and allowed things to get out of control by not watching closely. Say what? We'll get to that. Too, from our long experiences with those in power we know this, hubris colors their thinking more than does reality. Except, where that reality has to do with the size of their pockets. How did this come to be? And, does not a good general (military) know that he/she has to get out with the troops to know the truth?

Sensors are an analog for getting information. In any decision, and control, context, one needs feedback. That is, take the driving scandals that were running amok last year, at this time. As mentioned in regard to that, the key discipline would involve cyber-physical studies; as well, sensors become of real epistemological concern.

When a program doesn't have sufficient information, things can go awry. And, bodies may be required. Boeing found that it had to send armies of people out to help determine what was what. Was there some errant notion that computational frameworks could replace expert eye sight and observation?

What about lenses? Well, some of these would be related to sensors. Take eyes and their owner: would not rose-colored glasses influence attempts at accurate reporting? As well, consider that which is between the ears. Are those of the supposed highest order any more than those who have risen far beyond their level of capability (as the adage says)? Of course, we may add another, at some point, to the sensor and lens category, namely the filter.

But, let's stay with those two, for now. Notice in the white paper that mathematics comes into play for both sensors and the lenses. And, it is done in a non-trivial manner. In fact, a lot of the computation requires high-powered artifacts; that is, the class of computation that has been enabled by modern techniques is growing daily and is far out pacing any human parallel.

Except, we do know that people rise for more than their power-holding abilities; insight, to be discussed further, is important. But, that type of knowledge cannot be taught; one problem with science/engineering, it'll be shown, is that the educated intuition was thwarted long ago by certain types of preening intellectualism. That topic is big-T truth, of course,


06/28/2011 -- Have succeeded in getting this far with coming back. Engineering has KBE to keep it honest.

01/01/2011 -- This theme? We're done. Engineering is a shining example of human effort. Finance? Ah, cannot be said by a civilized tongue!

Here we go again, II

So, now we're hearing some tales, out of school, by Jon at flightblogger. Out of school? Yes, he is quoting anonymous sources at Boeing. Those who know that they ought not talk, yet do. Not real whistle blowers, as that would require them to come out into the light.

Well, before continuing here, the content of Here we go again still apply. What is necessary is an update. That will take some time, but we can look at a couple of issues, for now.

Firstly, from the beginning, I wondered about the leaks (the recent clamor in relation to WikiLeaks is very much apropos to the discussion) that Jon used. Were they ringers? How did he get such good pictures that would obviously belong to Boeing smuggled out? So many questions relate to that theme.

Along the same vein, there is the whole issue of how a company can manipulate information in order to influence investors. Of course, the legal positions on the subject continue to flux, yet that we're dealing with a near-zero game (which could be seen as patently illegal in other contexts) seems to never take any appreciable awareness in our collective minds. Many comments to Jon's blog posts have wondered about this.

Secondly, a grand and world-wide system is hugely appealing. But, it is so for different reasons for different folks. We can enumerate but will defer that to a later date. Let's look at three of those folks, for now. 1) We have the engineers and others who can do. Yes, the WWW (thanks to DOD for letting this little genie out of the bottle - I'm still amazed that we let loose that US taxpayer funded technology for the idiots to exploit) portends a whole lot of things that even scifi hasn't fully described. However, the old issue of map-territory (plus, being seduced by the allure of the abstract; the so intriguing notions related to computational ubiquity (to the limit of the universal computing device - why else the wizardry related to mathematics?); and a whole lot more). More power (pun, for the IEEE folks) to these pioneers, from whom has arisen all the marvels around us.

2) We have poor people who would like to better their situation. Unfortunately, for more than is necessary, many get trapped into unconscionable exploitation by the next group. Imagine: being tied into something so atrociously bad that is related to Apple (sheesh, Steve) and its new products, that one kills oneself (the solution was to wire, and make inaccessible, the jump points?). We'll be going into discussing the people, and not from a classist view either, at large.

3) Now, for the real as***es of the world. Yes, the best and brightest. Now, these types (can't live without them) are in 787 program, to boot; we'll not name names. They want to out-house (no apologies needed for the use) in order to exploit group number 2 while putting it to group number 1 who have been a pain in their rears. Yes. Just look at Wichita. Harry (yes, guy, I have your number) wanted it gone since the workers dared to boo him at a meeting where he and lil Jefe offered pop (as in soda - oh yes, it was iced) and the opportunity for them to tell the workers why they didn't need the union. This is another story to tell. Basically, when the opportunity arose, black-booted thuggery was let loose for several months that terrorized a whole bunch of workers. One has to wonder what would be the state of the program if Wichita was till within the folds of the company.

But, that's minor. Who the heck cares about a little city in the middle of the US? What is more of a concern is that there were many good talkers, using all sorts of lures, who pulled sane people into an untenable position that was more risky than not. But, hey, did we not just see the financial folks do the same thing? Despite recent mania (read Dow, et al -- on the backs of the savers, thanks Ben, big guy), there is more hurt than not (big bonuses for the fat cats does not cover up the crap).

What went wrong here? The plane did fly and for a long while. Now, ought there have been those pre-production crafts sitting there as if wishes were reality? Would one not think that the better method may have been to test the thing first and then work production? Cart before horse?


So much to look at. We'll continue to plod along. But, the basics need some attention: how do we know?, who the h*l tells the truth? (see Remarks, 'truth wears off' indeed), why CEOs? (as in, my ancestors did not come here, away from those arses, for me to have to continue the kissing mode), and much more.

How do we know?

The question pertains to both the before and after of any situation. Several things are of concern here, such as believability, trust, and more.

Let's take the 'after' part first, as we have said before that we do not have 20-20 hindsight, in many cases, though our 'ex post facto' state may be wiser (not necessarily, to which any thoughtful human will attest). This New Yorker article ought to help understand some of the issues. The Atlantic had a similar one (Lies, Damned Lies, and Medical Science), recently.

Now, on the before side, it's not easy either. The qualification, frame, ramification triad and undecidability apply, for the most part.


Now, we have another thing to ponder, especially when putting our seats on an airplane. But, as with all things technical, worrying about some of these things is just too difficult. Full speed ahead (paraphrase, as the context also demanded to ignore the torpedoes).

But, is this not true: any successful, democratic society requires a knowledgeable populace? Of course, there is the issue that we cannot let paralysis come from analysis.


So, in this case, we'll look at the issues from several sides even though one player says that it's of no concern. Expect the discussion here to continue, in a supportive role, while the video is analyzed.


12/20/2010 -- Not only do we need to ask who tells the truth, we need consider what 'truth' might be. A recent New Yorker article is of essence: The truth wears off. The few sentences of the article says this: "Just because an idea is true doesn't mean it can be proved. And just because an idea can be proved doesn't mean that it's true. When the experiments are done, we still have to choose what to believe". I might add, whom to believe. A similar article appeared earlier in The Atlantic.

Then, that same issue of the New Yorker has an article about the hypocritical mantras of 'free markets' that we're subjected to (Enter the dragon).

12/18/2010 -- On the finance side, Martin Weiss reminds us that Big Ben has grown the money supply by 1.2T the past couple of years. Then, he lowered the cost (interest) while giving bunches of money to the banks. These guys then loaned the money to us at a high rate of interest. And, pulled in the bucks. Of course, Ben had taken 1T of toxic assets off of their hand and put it on our backs. Finally, those jerks are getting paid big bonuses this year. We should have nationalized, yes, indeed.

Knowledge and compilation

As mentioned last time, we need to continue to discuss what motivates this blog in a constructive manner. Three years ago, a post looked at 'oops, loops, and oops. To belabor the obvious (nod to the Devil's DP Dictionary description of computer science), let's look at these three and then point to literature.

Why the use of "Consideration of 'oops, loops, and oops (at times, poops)" in the label?
  • 'oops - ah yes, as in hoops, referring, of course, to the operationalistic nature of life, liberty, and pursuit of happiness for us and of things in general. That is, action is the orientation. How do you like your daily 'oops jumping?
  • loops - again, tomorrow is the future extension of today as was today for yesterday and so forth. Is it not that texting drivers take advantage of the fact that all of their faculties are not demanded to cope with driving tasks, in most situations, and then consciously direct part of their remaining facilities to a distracting element all the while assuming that they can swap back to full attention if such is needed? That whole idiocy is such a good example of the latent risks that can develop into problems that it'll continue to appear here. Now, is it not true, too, that they know this about driving because of the familiarity? Did I hear you say, loop?
  • oops - to err is human; to be stupid about risk is what? Yet, error is for us to manage (to wit, what we see with information theory). Actually, if we took an error-based view as the underlying framework, it would be very interesting indeed. Of course, that would be an operational ('oops and loops) stance, as you know.


We don't need to mention poops, except in passing. How many instances can you pull out of your memory of some adult behaving like the diapered set (not talking Depends)? The real irksomeness? That we are then expected to clean the crap for these people.


So, raising our sights, we need to look at what 'compiled' might mean to the subject. Those who are computer literate might see the metaphor's appeal. It actually goes deeper. Just consider this ACM biblio list of citations on one paper.

The mere fact that we can compile suggests a lot. Basically, learning is the key. And, do we not learn via loops (iteration, etc.)? Is it ever over (hubris says yes)?

Notice that the inverse of compiled is deep. That is, consider how the concept of 'analysis paralysis' came to be. As a species, without compilation, we would have all frozen into some type of catatonic-like state long ago. Fortunately, there are embedded circuits to rely on, plus we have techniques, such as filtering, that are both part of our apparatus collection and of our acquired knowledge.

What all of this means will require a parallel development on the truth engineering side. However, the problems are deeper than those suggested in The Black Swan. Yes, we mis-use Gauss' work as we do a myriad of other mathematical ideas. That is one thing to continue discussing since it allowed the best and brightest to lead many on perdition-laden paths.


01/01/2011 -- 'compilation' was, earlier, in the mind (called learning) and in our artifacts, such as written material. With the advent of the computer, the ways to compile knowledge increased dramatically. What did not increase, though, was an appreciation of the underlying faults of those types of artifacts. So, there will be an ongoing effort, in that regard, to bring this to the fore.
