I am even more interested as I went to their site and they stated at least ten times that they are Canadian made.... As long as they are still manufactured in Canada I have no worry about theirs quality.
I am interested in knowing the model of your Yorkville.
I am certain that my Canada made Pioneers, wont last for ever even if the drivers membrane is in Kevlar, I am not interested in their current line of Chinese crap and the store that sold me good and reasonably priced equipment that even a listening room for A/B test, closed a few years ago, but the expensive store that sold Overpriced 10W tube amp for 3000$, store that refused to allow blind A/B testing btw, is still in business. So I would not know what to buy anymore without paying to much...
And fixing digital circuit boards no longer requires colored resistors.
You are right, nowadays it only consist of changing busted capacitors... I never saw another defect in a modern electronic device. Sure my sample is small since I do this as a hobby but it must be one the most frequent sources of failures or I won at the sampling lottery...
I have a pair of the last batch of Pioneers speakers made in Canada. The difference between the quality of those speaker paid 1200$CAD in 1997 and the others in the same price range is still audible in a proper room. The Kevlar made woofer are still as supple as they were in 1997, the wood still as strong...
That said, with my current listening room, as soon as I crank the volume, they sound like shit. I could replace them with a 300$ Polk audio pair and I would not be able to ear the difference but take them outside and they are heavenly.
Also the amp quality matters a lot. I recently repaired my father's vintage amplifier as the power caps were busted*1, and I was blown away by the sound pleasantness. It had a nice subtitle valve effect that removed the harshness of my listening room at high volume, I don't remember the exact model but it was an RCA paid 700$CAD in 1976. Those old school transistor were/are great, I think that I will build my next amp as I do not want to pay 5000$ for a class A amp, but still, I would like to enjoy the soothing subtitle valve effect.
1- I replaced them with ordinary capacitor of twice the capacitance. In the power stage audio grade capacitor are useless as you can hardly measure (with a scope) the difference... In the preamp, capacitors quality matters and that's why I choose RF grade components as they are usually cheaper and better than those with the audio rating....
And I forgot to add: it is a big fucking airplane so I approve of your low tech, 2.15$ (I over-spec the wattage of the resistor and the current rating of the Zener, as it is for the military after all) for one unit solution !
Is FIPS that important ? In my application servers I have a FIPS compliance mode, disabled by default, I have enabled it and nothing changed as far as my applications are concerned, when you read the documentation the only thing stated is that the setting enables FIPS compliance. I guess that if I had used one of the weak cypher available in that application server the FIPS mode could have protected me but that is only speculation as I did not....
You need a Java developer. And an Oracle DBA. And a Linux admin. And a Windows server admin. And someone to babysit your NetApp. And a network admin. And a.NET person. And on, and on, and on.
And then they still tell you that you need consultants because upgrading a critical part of infrastructure is very complicated.
This is what I hate about building software systems. When a company outgrows its office, they have an architect design another more adapted building, they usually sell the first and they have a professional construction company built the building according to the plan. However, when software is involved, the current system are kept, digital duck-tape is used and the new system is somehow working with the old one at the price of an incredible maintenance cost.
If we had a professional software architect title, much like the professional engineer title, we could have something that resemble the building/electrical/gmp codes. We would have software architecture cabinet that design and supervise the execution and we would have software construction companies... The assorted set of workers that are needed in software construction could form theirs own professional associations. And peoples and companies would be accountable for failure.
Everyone, who's professional enough to remain a member of his professional association, salary would raise up as it is usually the case when a title gets reserved. We could then refuse to support those crap assortment of systems as they would not be up to the software construction code.
Using big-O-notation to communicate with the business peoples is assured failure. However, when you are talking about the scaling properties of an algorithm, it is the proper terminology.
you missed the problem translation part, that part of a true CS education, enables the utilization of one well tested solution to a seemly unrelated problem. Math rule's, I recently used a part of Dijkstra algorithm to optimize the generation of oversized PDF, I went from 6Gb of ram to 700Mb to merge 8Gb of pdf down to a 55mb file and the performance went from 4 hours to a big 55 seconds on the same hardware....
You might ask what the link between Dijstra and a pdf file... Well a pdf file is a serialized objects graph and if you have a reference to an object too far away in the file, the printer or the viewer will slowdown, if you store every object as a copy you get a ginormous file and everything slowdown. Since you can modelize that as a weighted graph, you are able to calculate a distance field between the repeated objects. As you merge you use your look-up table, to take the following decision : if your copy is to far away (+-100 pages), store it as copy, else store it as a reference...
Mass printing is a common problems and yet I did not find any good product on the market, each of the product I tried was generating crap files (2-3 Gb when I generate the same document with file size of 55Mb) or was taking forever (6 to 10 hr) to complete when I do this in 55s...
. None of those scale. As complexity increases each of those techniques reaches a point where they fail, badly.
traditional Dijkstra implementation : O(edgesCount+vertexesCount*ln(vertexesCount)) how does that does not scale ?
I assumed that you meant elements count when you wrote complexity, if not please specify what kind of complexity are you talking about. You might have might accidental complexities, but those are slowly being taken away by our tooling's.
You might have meant business domain complexity but if you meant that, it is related, as if you can translate a problem into a path finding problem in a weighted graph, you then have a solution with a relatively low O bound.
So please specify what did you meant by complexity ?
I took 30 as around here it seems to be the cut off point but it is pretty arbitrary and I assert that studies on that subject are warranted to find the cut off point per quantile per region.
CS is someone using is knowledge of theory to suggest adding a bloom filter to a database before performing a membership test in a big set. IT is the guy who manages, configure and deploy the servers...
I am over 30, for me and almost everyone I know in the age group, what you said is true. However, for almost any 20-something I know, the opposite is true. So I postulate that this is a generational thing

Thank you both, I will surely use what I learned from the posts, next time I choose a replacement capacitor.

step1();
step2();
if(!condition())
step3();
step4();
now if it were a while true, the following construct would be justified
step1();
for(step2();condition();step2())
step3();
fat, sure they were; but broke, I never saw one. Now, if you meant broken that is another story...

would you really need much more than a Zener diode and a resistor?
not unless you care about density and power efficiency....
assume that the thing takes in 1A or 5W
you have (28V-5V)*1A = 23W to dissipate out of your (23W/1A/1A)=23 ohms resistor
