A few people have been asking how this worked:

He bought put options (his right to sell at a particular price) below the market price and sold call options (a counterparty's right to buy at a particular price) above the market price.

If you price them right you can use the money from selling the call options to buy the put options which makes it costless in net cash terms.

Market price was: $95
Put: $85
Call: $205

The reason the spread between the two is so high has to do with the time value of money and some other technical stuff, but those were the collar values.

Yahoo's stock went up to the $230s which was above the call option price, if the options had been exercised at that time, Mark Cuban would have lost out on the gain in price above the cap ($205). By the time they were exercised however, the stock was totally in the toilet and Mark Cuban was able to sell at $85.

It's not really an unusual deal but not many people were doing that in 1999, collar trades are much more common now because people remember the first crash.

Fellow comment discarder here. You wouldn't guess by some of the long-winded replies I've made across various sites but that's a big part of it I think. I often write comments as if I'm having a conversation in my head so there's not a clear structure like you'd find in an essay or "proper" written piece. Then I start thinking of all the ways someone could miss the point and end up rambling.

Remember with turbine powered bombers the flight takes 5 hours crossing the aerial zone of at least 5 NATO countries with modern aircraft and radars. And we know it was loaded with nuclear weapons, because of radioactivity.

The Typhoon is unable to engage the enemy said by David Cameron to pose the biggest threat to Britain’s security. And it will not be able to do so until 2019 at the earliest.

In fact, maybe the paradigm of airplanes is outdated since USSR giving cheap missiles and crude radar to the viet kong have proven that in terms of costs planes can be shot down with a 1/100 ratio in terms of costs. Plus aerian superiority paradigm (a WWII idea) works against developed countries relying on a dense industrial country. But, it does not work against people relying on AK47 and propane bottles coupled with a simple radio system.

Money is the nerve of war.

Angles: Sorry I can't find the article explaining how the DOD imposed using a software for B2 (and not F35) that limited the possibility to make nice curbs.

However just look at the plane. And remember any physics lessons you have been taught : sharp angles make discontinuities. Discontinuities are easy to spot.

Stealth anyway is a scam.

B2 were spotted by US radars technologies bought by french since 1991 with networked radar (thomson). Validated during 1st iraki war while radar operator could put a name on the weired stuff they were seeing on screen they already saw flying over European space without authorization. (Spying allies is really not nice)

You can evade one radar by deflecting signal. But if in a network of radar the signal is reintercepted, then it is bad for the plane.

Also since 2000 it has been proven that the flight of a stealth plane above a normal "cellular phone grid" can be detected by the additional energy that it bounces back.

Still with networked radar, stealth planes can make "holes" of expected energy. (ionosphere does reflect a little part of energy, and stealth fighter makes "shadows/holes") it may require bigger wavelength though.

With IR detection, plane still leaves energy traces (like air friction).

Stealthiness only value is in plane vs plane fight to diminish the electronic signature, thus a frontal stealth is more than enough.

Stealth is a costly arm race. That is exactly what killed USSR that tried to fight USA IDS program (that was a scam).

Strategic thinking must address the costs problems.
We use 'ProxyCommand' constantly with bastion servers to help protect our infrastructure. We use 'ForwardAgent' much less, but it's still useful for some testing purposes or one-offs.
Fighter jets and aircraft carriers are basically war penises. Whoever has the coolest, fastest, and most powerful ones will look amazing to the rest of the world, but in the event that someone actually wants to go to war, the penises will be the first to go. No one needs a penis.

Hmmm...this analogy fell apart.

Messi Get Cute Gift from Antonella
I've applied to probably 100+ jobs in the past two years. I tried keeping track for a while and later felt it was not helpful. Occasionally I have to dig back through emails to verify things, like whether a recruiter submitted me for a certain company, and it can be a slight pain. But I don't think I would get enough value out of a whole app dedicated to this topic to bother to download it, and I am probably an ideal user of such a thing.

Third party recruiters are the number one pain of the process. They don't respect candidates; they don't want to hear about your goals or your search constraints; they just aggressively talk over you. And I'm even talking about the so-called 'good' recruiters that you get referred to by word of mouth. Even they will break your heart.

The second pain point is well known: everyone uses different online application portals, and everyone has different requirements for manual data entry. I would have expected by now that applying at any company is as simple as just uploading a resume and clicking through some boilerplate agreements or ethnicity surveys that we would all be wise enough to always opt-out of. But I'm still dealing with application sites that look like they were built in 1995 and require upwards of 30 minutes of manual data entry.

Apps that could alleviate the pain of these issues would be way more valuable than organizational apps. The pain of the disorganization is just not that meaningful.

The recent dip may be attributable to uncertainty over the release of windows phone 10, and also Microsoft has tended to release new phones that tend to be worse than existing phones. I delayed an upgrade waiting for a good cheap device with wp10 (Lumia 550 is not it), but got a 640 (with 8.1) when my phone had an accident.

WP 10 on low end phones is very laggy and horrible, which is also not good.

For real publishing, I think TeX is still the state-of-the-art. It still produces the best-looking documents put on paper (granted, one needs to give it a decent font to do so…).

Also, this kind of question usually leads to me looking at other items related to the thing posted that I was unaware of. I don't think it's a bad question at all. Hell, sometimes the author comes in to explain it!

This is a race to the bottom. Most companies today prioritize the satisfaction of the stakeholders as follows:

C-Level Management->Shareholders->Customers->Employees

In this environment, one must be financially prepared to retire early once you reach your 50's because you will likely be replaced.

Replacement by H-1B's is just a symptom of a greater underlying problem: The need to enrich management and shareholders.

Instead of C-corporations which put profit above everything else, we need more public benefit corporations (B-corps) which have balanced priorities.

While this is meant I think a little tongue-in-cheek, it's always important for everyone to contribute value. QA is vital to the success of any project, if all it is functioning as is a Boolean check at the end that says "good" or "bad" and it keeps spitting out "bad" then it is not providing value.

QA needs to be implemented throughout the process, and it needs to be capable of feeding changes into the system at different stages to make sure that it's providing feedback at the earliest possible moment.

I know nothing about this project, so I don't know what their issues were along the way. Definitely they need real hardware at the end to test with, but I hope that they had mocked out the expected hardware interfaces such that they could have quicker turnaround earlier in the cycle.

I completely agree. Honestly regular expressions are hard to get a handle on anyway. I've done software development for about 12 years now and I probably run into a regular expression pretty regularly and I still find them hard to read and understand. Almost every single time they do things that can easily be accomplished with a loop and a tiny bit of string manipulation and, honestly, even if the regex was a little faster it's unlikely to be so much faster than you need to make the micro-optimization of using regex instead of some looping.

I try to avoid regex where possible and in the event that I do need to use it I try to document it the best I can and to make sure it's as simple as possible to avoid weird issues like this.

However the excel solution has a lot of things going for it :

1) applications/reports built by the people designing and understanding the underlying needs and inner workings of whatever they're offering. Whilst very good programmers can match this (given enough - that's a lot - time), average programmers won't even try.

2) excel sheets require nowhere near the manpower required for your alternative. That factors into a cost-benefit analysis that may not favor real development.

3) Speed of development. Markets change. Investments change. Sometimes literally in minutes. Anything involving more than 1-2 people who are intimately involved in the strategy itself cannot possibly keep up.

4) Excel is in fact a pure functional programming language [1]. Unless you deeply understand excel I wouldn't be so quick to call it stupid. There are entire classes of bugs that simply can't exist in excel spreadsheets that are regularly found in programs.

"Many macroeconomic models exclude the concept of marginal utility of money."

I'd have to [citation needed] right back at you on that. That verges on the mathematically impossible; it's written in the very basic most elements of economics itself. I wasn't kidding about the math completely failing if you don't have it; the entire concept of trade breaks down [1] without diminishing marginal utility.

What's more likely happening is that you're seeing Newtonian physics equations and complaining that the equations "neglect" quantum mechanics. They don't, really, they're in there, they just aren't obvious, and it breaks down when pushed too hard. (So non-obvious it took centuries to discover in this case, not relevant to the econ case.) If macroeconomic models don't appear to have a term in them directly that says "here's diminishing marginal utility", it's only because it's so deeply in the foundation you can't see it through the stuff built on it.

[1]: You might still get trade in a world without diminishing marginal value, but one in which you still have different personal valuations. However, instead of a world in which a lot of people have a little bit of everything, which is what we observe, you would get a world in which each individual has a lot of only the thing they value the most, having traded away everything else they have to everybody else to obtain that one thing they value most. If that sounds weird, well, yes, it is weird, because we can't imagine not updating our value functions based on what we currently have; it's so fundamental we literally can't imagine not having it. Note: This is not "wealth" concentration... in fact what you think of as "wealth" doesn't even exist in this world and it would indeed produce a world beyond desparately poor as these crazy people literally focus on food to the exclusion of water, or water to the exclusion of shelter, and so on. This is a world in which one person has all the oranges, and one person has all the apples, and one person has all the blue rocks above a certain size while another person has all the blue rocks below that size. It's not the world we live in. Diminishing marginal utility is a fundamental truth of the world, not some economic mumbo-jumbo... not having diminishing marginal utility would be the crazy economic mumbo-jumbo.
The problem with a lot of such material is that it's very U.S. centric. Being from Eastern Europe a lot of the advice in the book is not relevant.

I was speaking of the angles in the shape of the planes design.

Have you ever seen a diffraction pattern caused by any discontinuities?

I have seen thousands of them ... the fourier transform of any discrete functions makes very nice detectable pattern that says : "NOT NATURAL". And that what radars are trained for spotting.

And the more symmetries the more the pattern reinforce itself saying: human made technology spotted. (Curie principle : symmetry in causes get propagated in the effects)

Have you seen a lot of natural object that are both discontinuous and symmetric and the size of a plane?

EDIT : I forgot to explain the relationship between convolution of signals and FT but I guess everyone is educated enough to know that convolution of signal is the base of radar detection and that Fourier transform are related to convolution.

> High demand with unmatched supply means higher prices.

You've just negated your own argument that home ownership is more affordable under BI. BI would increase disposable income across the board, increasing demand for purchased homes that is not necessarily coupled with an increase in supply. Prices go up overnight.

And home mortgages are low risk now - rates are about 3.5% which is among the lowest you can get for any loan, especially one multiple times higher than the borrower's yearly income over multiple decades, and any responsible person will be paying their rent long after they've switched their diet to PB&Js and ramen noodles. It's the first thing coming out of every check.

When you go to the hardware store and ask for something to pound nails, they give it to you. When you ask people what they use to pound nails, they say they use this. When you're hired to pound nails, they often insist that you pound nails with this. 99.9% of the people who use this on a regular basis use it exclusively to pound nails.

Given that context, it makes little sense to say, that's unfair, it's really a screwdriver.
