I have to agree. Pysch 101 was the best course I took in college outside of my Comp Sci classes. Having classes with group projects in business and english were really helpful from a sheer communication standpoint but there were parts that were overdone.

At my college my major had specific classes that we could choose from for the electives and only a few "true" electives. I think it would have been much better to just allocate the rest of the hours to pure electives and just give a category.

Choosing what I want to learn about vs being told "learn one of these three things" would have led me to be more interested in the subjects in the first place.
Flaw in that you can match songs you down own or that the meta data might be wrong?

David Axe has a great, thorough writeup on how F-35 became the worst, most expensive, plane in our arsenal and will probably just get our pilots killed.

I was extra mad that they're moving to get rid of the A-10's in favor of this garbage. Originally learned about them with the A-10 Tank Killer games on PC. Later read how they shredded the opponents' vehicles in one campaign after another, even recent ones, despite being highly exposed to enemy fire. They're beasts. And that's just one example of something that does its job more effectively and at better cost than F-35... which is also being decommissioned to support F-35 program. There's quite a few more that each could've been updated with less money than F-35 took.
I don't... thanks for the tip. That looks like it would be really handy.

> I think someone only earning BI probably wouldn't have the resources or motivation to do Bell Labs-style research.

It's sure as hell better than earning $0, being forced to work some shit job 60 hrs a week at a SV startup providing SaaS full of proprietary software that will circle the drain in a few years, receiving money from a VC that truly doesn't give a shit about the greater good.

Instead said person could work 15hrs at that shit startup to live more comfortably, and spend the rest of their time working on ffmpeg or something. It doesn't have to always be Bell Labs tier.

> Unless you're implying that all of a sudden with the help of basic income, people's interests and preferences will change and result in a glut of engineering talent I don't see how it's at all relevant.

With BI many people will no longer be tied down to the rat race and will actually be able to work on themselves. It has nothing to do with interests and preferences. Time is money.

While the F-35B has now reached what’s called its “initial operational capability,” the plane’s development is not complete. There are still updates to the software that need to be implemented.

Did the "fire the gun" software get installed or is it still a to-do item?
In short, if I understood, the author used

SELECT c,d FROM t WHERE b=X ORDER BY a DESC LIMIT 1

on MySQL and was surprised to find that MySQL was using index over a and in his opinion fully ignored the existence of the index over (b,c) to discover where b is equal to X? I admit I didn't understand his explanation why, especially not why it would maybe do the right thing with the LIMIT 2. I can't imagine that any serious SQL engine would ignore the possibility to use the index in such a case.
You, apparently.
I've learned quite a bit from IRC (mostly in #stripe). Though the learning has been way more indirect since I spend most of my time helping others. So people would ask "how do I do X?" and the learning comes from researching ways to do that and evaluating the pros and cons of each. The second way that I've just learned is by getting exposure to how a ton of people have integrated certain aspects.

Stack overflow is great for solving individual bugs (which definitely works in some IRC rooms), while IRC is more of a "how to do something" or "why should I do it this way" type of environment

And how would you feel about the new scale I proposed? It gives you the scale you want and it's easier to convert to scientific scales like Celsius and Kelvin.
If you do that, then you already have the song, so you're not really getting anything out of Apple that way (besides making it easier to play that song on your other devices).

Basically, you can use xmlhttp to fetch any webpage becaused of relaxed restrictions. then use DOMParser (a built-in browser component, that you can even shim) to create a virtual DOM of that xmlhttp result, and execute regular querySelector and querySelectorAlll queries on that :)
The A-10 is an absolute beast against the people we are currently fighting. It also can hang around and provide cover for a much longer time than the F-35.

Funny how similar this is to just a simple filesystem.
It reminded me of two unrelated things: Erlang and FFTW.

Erlang due to its error handling philosophy and FFTW due to the following:

Question 4.1. How does FFTW work?

The innovation (if it can be so called) in FFTW consists in having a variety of composable solvers, representing different FFT algorithms and implementation strategies, whose combination into a particular plan for a given size can be determined at runtime according to the characteristics of your machine/compiler. This peculiar software architecture allows FFTW to adapt itself to almost any machine.

For more details (albeit somewhat outdated), see the paper "FFTW: An Adaptive Software Architecture for the FFT", by M. Frigo and S. G. Johnson, Proc. ICASSP 3, 1381 (1998), also available at the FFTW web page. [1]

Edited for one more comment:

The last paragraph also reminds me of Alan Kay with its focus on the interaction between systems and not their specific logic.

Writing clean code is not an academic exercise. It means comprehending it takes longer, writing features takes longer, testing it takes longer. It makes every interaction with the codebase harder.

That might not be quite as bad in a proprietary codebase since you have somewhat more of a captive audience, but in an open source project where you want a long-tail of contributions from many people, that is a serious problem.
Study: We've wiped out half the world's wildlife since 1970
David Axe exhibits poor engineering understanding of the aircraft, which results in him interpreting the reports that he reads in ways that are simply not supported by the source material. As someone with detailed knowledge of the program, I consider his reporting to be misguided at best and potentially malicious at worst. At the very least I wish he would consult someone with flight test experience as he writes.
1. Start with a profile of what kind of missions are run and which planes do them best.

2. Identify any overlaps to spot consolidation opportunities that don't increase risk with "jack of all trades, master of nothing" results (eg F-35).

3. With or without consolidation, invest money in each plane that proved most effective in the field and simply upgrade it.

Last test I saw with F-35's vs F-16's saw the F-16's win. So, apparently it wouldn't have taken many upgrades. ;) I'd upgrade our top interceptor (eg F-15/F-16), multi-mission (esp F-18 Super Hornet), anti-vehicle (esp A-10), recon (eg U-2 or drones), and ECM craft for starters. Those would be volume while we invest some into improving premium aircraft we use in lower volumes such as F-117, F-22, and B-2.

I'd say this would be a nice start. At ten billion into each, it still wouldn't touch the F-35 program in expense despite offering way more in results.
Sorry for downvoting, I misclicked.
Maybe you stumbled into a business opportunity? On the other hand, judging the ability to program is very hard.
That does look pretty interesting. Here's the english-language page with examples: http://smilebasic.com/en/

"Because Clojure rocks, and JavaScript reaches"

-- Rich Hickey

(or so I've heard)
I don't know enough to have a solid opinion, but at a surface level I can see enormous value in the F35.

The growing threat against western militaries are asymmetric threats, and the US's modus operandi for quite a while has been to empower the carrier strike groups to project power over wherever these threats may start heating up. If a carrier has to carry a bomber and two escorts and now an F35 can be 80% as good as each of those at their respective task but take up < 33% of the space, that seems valuable.

How does this whole F35 thing pan out when logistics like that are taken into account?
The one mistake that ultimately destroys modern companies
From 2012: "The government now projects that the total cost to develop, buy and operate the Lockheed Martin Corp F-35 Joint Strike Fighter will be $1.51 trillion over the next 50-plus years, according to a Pentagon document obtained by Reuters"

Dunno if it's true but it's still mentioned in the Wikipedia article.
We're still talking about over $650 million per plane in total lifetime costs, even from the optimistic reports -- just an absolute boondoggle of a program.
> I'm not sure what is being advocated.

Nothing. The article exists to make you think, and consider the history of this piece of Internet space. It doesn't need to advocate for something.
What are you trying to say here?

proof_of_negligence -> (proof_of_benefit v ~proof_of_benefit)

easily simplifies to

and therefore doesn't need a case to be made for it. It's always true.
Yeah this seems to be a big issue just by looking at it and makes me wonder why they didn't use everyday parts like a chain or a sprocket off a bike.

Also I wonder if you could just do all this with a refitting of a rachet lever hoist or something similar.

I pointed to the latest selected acquisition report, which is the definitive document regarding program costs. It is to be considered the authoritative source for cost data related to this program. It is more recent than the document referenced in the Wikipedia article.

Indeed, although I would wager that current CS programs don't effectively gauge that either.

I think part of what's interesting is that there is this massive proliferation of non-college sources of education for CS, but none of them seem to have the clout and accreditation that a lot of employers look for. So why aren't universities copying the coding bootcamp model as a hybrid with CBE? I hope it's not just because they're being sticks in the mud.

Bikeshedding is piping up on trivial issues to draw attention to yourself in a group. There's only two of you? You should have enough mutual trust such that nobody feels the need to show off.

I'd suggest putting a stop to any more design meetings. Get a prototype working, iterate from there. What needs to happen will become apparent. It's all smoke and mirrors in the beginning anyhow. Take a page from the Italians and their fancy A-GEE-LAY methods.
More generally, policymakers tend to be concerned about their constituents and taxpayers over those who are neither.

JSON parsing is a major problem on Android. When I also first ran into the 35ms parsing I thought for sure I was doing something wrong. Nope.. the latest phones can get down to 4-5ms JIT'd but still iOS is an order of magnitude or two faster which completely changes your architecture decisions.

Why this can't be integrated in to be fast & native I've never understood. It should have landed in Android a long time ago.
Manned planes will fly for several decades still, and even upcoming generations will most likely be optionslly manned rather than unmanned. The line will blur between manned and unmanned however.
Today's "drones" have more pilots than the manned craft! Often 4-5 for even a short mission. There is no autonomous flying. Quickly reacting autonomous fighters is still sci-fi.

The problem with the F-35 project is mostly that it somehow was decided to replace the Harrier. Replacing the F-15/16/18 isn't a problems. Replacing the harrier with the same craft is an engineering nightmare.

Upgrading old platforms is done continuously, up to a point where an upgrade would be so expensive/radical that a new design is better. Sticking more electronics in an old plane isn't easy, the power and cooling requirements can require big redesigns, for example.

The planes it replaces are certainly near the end of their lifespans and have been upgraded a lot over several decades.
What they should have done is not make just one plane. A replacement for the F-15/16/18 would have been much easier.
Threats to those with means, but anyway, we're led to believe this should not happen in medicine, a life is a life. It's all very sad anyway.
That was not a dog fighting test. It was a test of F-35 flight controls. The F-16 was only present to provide a visual reference to maneuver with respect to. This is the kind of misconception that arises from David Axe's failure to properly understand his sources.
Good for them.

People who don't like abortion (for whatever reason) should be all in favor of better contraception methods. What better way to avoid an abortion than to not become pregnant at all? Those who oppose contraceptives reveal themselves for who they really are: people with middle-ages thinking who think that a woman's job is to just bear babies.
Yep, I did eventually find that. Having to search for it was frustrating; so much of the copy is devoted to describing what Baker Street isn't (hey, doesn't use consensus!) and not what it is (uses a single node, TODO: master/slaves or chain replication or blah blah blah). And it's kind of an important point, because it changes this from "might give this a go for a less critical service" to "unusable in the short term."
I had a ton of Apple Music problems initially, but I couldn't be more happy with it now. I love Apple Music. It screwed up the metadata all over my library, had problems with adding playlists to my library. It turns out it was all because there's no way to reset iTunes Match. The old iTunes Match songs in the cloud were screwing up everything. I had to use a second computer to delete the songs and create a blank library to Apple Music before all my music would sync to the cloud correctly. Apple really needs to get it together with their iCloud platforms. The amount of bugs is getting embarrasing. But Apple Music as a service is pretty awesome.

Truly amazing craft. If you're 15 - you can use that book + rec.autos.makers.vw.aircooled and drop the engine yourself; replace the clutch yourself; find the distributor drive shaft that was installed backwards and got you the car for $600 in the first place ... At least that's my story.

Aircooled VWs are so simple. That book was such a good companion, down to the first part which explains "front is front, up is up, back is back..." complete with a diagram. When upside-down & greasy, knowing exactly what the author means by "reach to the upper left of the engine" is important.

> Bad idea? Sure. But once you know the enemy you can deal with it

Why surround yourself with more enemies than those that inherently exist in your business logic/problem domain? The problem with PHP is all of those "no big deal tiny issues" add up to something reminiscent of death by 1000 papercuts.
I would be surprised if the prevalent economic models will continue to apply. Think Walmart, Costco, Amazon and how they leveraged their scale to drive efficiency through the ecosystem.

The prevailing models during those times were revisited which included prices, contracts, payments.

In your specific example about car washes, I envision a huge warehouse with multiple floors to do automated car washes which is super efficient. This will happen as there will be a metric that will show how a minute saved on the car wash floor can save the company millions of dollars because of their scale. There will be no "car wash" dealership to negotiate with.

The "right to be forgotten" is antithetical to free speech and free press. The news, even when it reflects on someone unfavorably, is a matter of public record. Just because it's about you does not make it "your" data or confer some sort of moral right to decide what happens to it. The public has a right not to have information disappear out from under it.

Subselects are almost always better when it comes to optimization.

The author is really amateur. His inability to do what amounts to SQL I in college is quite telling, and somehow hes opinionated enough to write a huge blog article about it. I like the analysis and diagnostics of the query planning - but his query writing is trashgutter.

SELECT c,d FROM t WHERE a=(SELECT MAX(a) WHERE b=X from t)

That query is what I would have done from the getgo. It reads much better and is going to pretty much always be the optimized query plan. This is basic stuff...
