Well, everyone knows that any site outside of the top 10 is just a hobbyist site that no one reads. Scoff!

Thankfully, I don't need to discuss with you whether or not I need XCache. More thankfully, I didn't see your poor advice before trying XCache for myself. It makes a dramatic difference in time till first byte on pages that aren't yet in the static cache (and all pages for users who are logged in).

How dare I try to improve performance for the puny couple million people who visit my site each year, even though Ken Shaw doesn't think they deserve it?

Anyway, I find myself asking why in the world I'm still wrestling this pig when I don't enjoy being muddy, and I realized that there really is no good reason. So, I'll leave you to it and let you have the last word about how bad I am at technology, Linux, updating my LinkedIn profile, using apt-get, etc.

Epp's Discrete Mathematics with Applications is a nice book that covers much of the same material as this MIT class, but at a slower, easier pace. It's highly suitable to the beginner.

You should know high school algebra and precalculus to be able to read the book. Trigonometry and calculus are not prerequisites, although you will probably want to learn those too.
In SF the way most people sell their old bikes are via craigslist. are they city-specific markets, where people meet up in person for the actual exchange? - Yes.

In my experience both selling and buying bikes this way its not been not as difficult an experience as stated in the article. My wife has sold two bikes on craigslist, she sold them for a fair value (She knows bikes well) and everyone has been happy. As a buyer I can get a pretty good assessment of a bike's value based on some pics and a description. You can actually find a lot of good value in the used bike market if you're comfortable doing some repairs yourself and you know what to look for. There's a lot of sellers who have an old bike in the garage they're just trying to get rid of when they move that might be a nice steel frame commuter once cleaned up.
Hence, patreon. I hope eventually everyone is on there and I can start contributing more materially to the artists I love than via exposure and the occasional thing they sell.
Yeah, it's surprising too. I was programming for a good week in Go before I discovered anonymous fields and how they worked. They really need to do a better job of explaining that they have a form of inheritance in the language that allows structs to exhibit polymorphism beyond being an interface as it isn't really explicitly stated anywhere in the docs. The section in the FAQ that answers if Go is an OO language never makes explicit reference to them, and in the language spec they don't get their own section.

Possibly, but as I understand it, the software is tightly coupled to the battery hardware; if you were to swap in a different kind of cell, or even the same kind of cell but from a different manufacturer, you would have to rework much of the software. That's why I think it's better to view the storage cells and the software as a single integrated "battery" system.

> how dare you compare your simplistic, cheap machine to a car legally

The article is using the term 'lemon' as an economic term, not a legal one. It suggests that the 'lemon problem'(economic term) in used car markets also occurs in used bicycle markets.

The use of the term in economics goes back at least as far as 1970, so 5-10 years before the first 'lemon law' in the US.

> "dozens" of emails a month

In his Ars Technica article he claims to have been sending 5 takedowns per day (that's more like hundreds a month). The dozens per month are just the minority he's deemed commercial. He's continuing to go with takedowns for all of the rest.

> But their business model is built on profiting from uncertainty and fear from the people they accuse of theft.

It seems clear that he's the one making accusations; he just hands it off to them. Its not some automated system or evil lawyer going after obvious innocents, unless you're accusing the artist himself of initiating malicious lawsuits.

Percentile and Quantile Estimation of Big Data: The T-Digest
Not according to the article I linked, which even has a four-paragraph section called "metaphoric meaning" that does not extend to that meaning; nor do any of the examples in the long list of examples under the section "modern commons" show such a meaning.

The term "tragedy of the commons" simply refers to a different concept. It's just not what it means. It means common resources become less useful over time.

This is not a statement about investment; it's just that the effect that is described is quite specific. You don't have to use an incorrect term to describe what you're talking about.

but they are already pretty much free and easy to get. do we have to put them on for everyone too? do you want to just mail a package to every person in the world once a month? I mean, what is your solution to make people actually use them. They are already free!
The problem was challenging.
The solution was exceptional.
So, maybe something about the
person who solved the problem
might be exceptional, that is,
might fail to fit some
common patterns?

Or, in this case, we can't call
the success luck. So, for
considering what is likely to be
the situation
or characteristics of the
person with such an exceptional
success, where are we to look?
Are we to look at the dozens
of people we do know or the
thousands of other people, all
of whom tried but failed to have
such exceptional success?

So, we didn't see him at an
AMS conference; he's not a
full professor at a top
university; he doesn't have
a wife, 2.5 children, a
3 bedroom, two bath house,
and two late model cars;
...? So?

If we hear a claim of some
astounding accomplishment, then
maybe (A) the accomplishment
is nonsense and the person is
exceptional because they are
a crackpot or (B) the accomplishment
is terrific and the person is
exceptional because they were
very successful. So, with
either (A) or (B) we stand
to see things exceptional
that don't fit common patterns.

Net, if really want to look for
the very best accomplishments,
then we shouldn't reject people who
look exceptional, that is,
don't fit some patterns we learned
from people who haven't had
some terrific accomplishments.

And, in this thinking, we have to
notice, in business there can be
essentially some very good luck
but not in pure mathematics
complete with theorems and proofs
that can be checked with high
reliability. That is,
in business, people who
are not very exceptional
and do fit common patterns
can still be very successful
because of essentially luck;
so, in business can find people
who fit nearly any common
pattern and also are exceptionally
successful just because of luck;
can't do that in pure math
there luck doesn't work!

Let's say I'm building a web app and develop my own patterns and practices. Obviously it'll be a bad idea to have everyone working on my project create their own patterns and will make sense to mandate everyone follow one set of patterns so we don't have to keep context-switching whenever we're working on a different part of the app.

To an outsider who needs to now contribute code to my web app, what's the difference between following my patterns and following a framework's patterns if a framework was used instead?

What's good about most frameworks is the fact they come with documentation, tutorials, tests and all that good stuff so someone new to the framework can quickly get up to speed. The author even admits to having people have problems understanding his architecture.

My advice to the author is don't worry, people will eventually get better. JavaScript seemed inaccessible to a lot of people (including myself) until jQuery came along. The more jQuery code I wrote and gained more experience in JavaScript, the more I learned how little I needed to use jQuery to accomplish a ton of stuff. Backbone, Angular and other frameworks will probably have the same effect on people some day.
Wondering where jQuery fits in the author's mind right about now.

Yes, it's a "library" but come on, all the framework versus principles narrative applies with that too.

Directly interacting with the DOM without abstraction seems way too risky, in exchange for some bloat.
>But operations on fixed point numbers act differently on the integral and fractional parts of the numbers

Not really. Not in any way different from floating point. Can you explain this point? The efficient way of doing fixed point is to store it as a single scaled number, which is also how floating point stores the mantissa. You could split it into two numbers, but you could also split a mantissa into multiple numbers if you really wanted, it doesn't really change the math.

>(in part because it's impossible to have a pair of fixed point numbers of the same type, but so different that n+1==n).

I'd disagree there. You can have fixed point denominated in 100s as easily as you can have it denominated in .01s.

>Some operations lose a constant amount of precision, others lose more precision the more different the numbers are. None of them act differently on the integral and fractional parts of the number.

Precision is only 'lost' compared to other floating point operations. A long double won't ever have less precision than a 32.32 fixed point number, unless you're using numbers that wouldn't fit in 32.32 in the first place.

In no way do you have "a single bit" of useful precision. Anything that can corrupt the upper bits of a floating point number can corrupt the upper bits of a fixed point number.
> Per this article, only 20% of people in Bangladesh have traditional bank accounts. Yet 33 percent of Bangladeshi men have used mobile money. Mobile money has replaced the bank account.

Unless I'm mistaken, that still doesn't sound like it would actually help the people that they claim that need it. You can't put physical cash into the mobile banking. [Well at least without using a transaction service, which would tack on fees]

> Are there legitimate needs for a cellphone in their life?
> Do you have legitimate needs for a cellphone in your life?
> For a wallet, credit and debit cards?

We're talking about different cultures. They've survived and accomplished life goals without a cellphone in their life. Could I go without a cellphone? Absolutely. I could go to a landline. But thats not the point here.

> A cellular phone will help someone learn a fair price for their crop, good, or service, and allow them to contact buyers. This will do more for their income than a suit. But access to cellphones and mobile money doesn't just benefit people by increasing income. Giving women the ability to make purchases has listed benefits in the article:

You're making an assumption that they will use the phone in the best case. To call someone over a fair price.... but you have to know those people in the first place. To further drive this point home: If you were buying a car, who would you call to compare prices? (Using internet services on your phone won't count for this.. as that in this culture it would be a new concept to find others in the market via a mobile)

> "Women spend money differently from men. They tend to invest more in the health and well-being of their families — as much as 10 times more. They give priority to spending on health care, nutritious food and education. A child born in a household where the mother controls the family budget is 20 percent more likely to survive — and much more likely to thrive."

That sounds like a gender based stereotype.

That would make sense for the advocation of more mobiles. However, my concern is about "toping up" accounts. (Converting physical currency to the electronic) I still see a larger need for a bank account.
The premise of the article, at least at the start, that CBOT contracts are not useful to Kraft because Vomitoxin limits are too high is misleading. The author appears to be ignorant of this fact, but as a farmer I can assure him, and everyone else, that the vast majority of Wheat delivered is far below the Vomi limits attached to contracts in general, and that also does not mean that those contracts are not useful for hedging and/or accepting delivery of wheat with low tolerance of vomi.

@Scott

I thought this to myself as well. Is this the outcome of the new society were in? Nobody knows anything beyond what they do for a living? .. Aren't willing to watch a 5min youtube video entitled 'how to buy a used bike'
.Whatever happened to googling and figure it out?

Is this where the big bucks are now? Solving things people could google? ..

Nobel prize winning papers applied to buying a used bicycle.. I thought april fools was over.
A bold new era.
Putting aside the fact that derailleurs are relatively cheap and buying a new bike to replace a seized derailleur is not economical (unless you get stuck on an upgrade path that makes you also replace the shifters). And putting aside the fact that bicycles needs regular maintenance and regular riding to stay in top condition (seized derailleur only happens if you basically leave it sitting in the rain, or never change gears)... The lemon issue only really applies to bikes that you buy sight unseen. You want to check for cracks in the frame and a worn drive train. Both of these are relatively easy to learn how to do.

Having said that, I wouldn't usually buy used either for a variety of reasons. If you are buying a quality bike, the damn component manufacturers keep improving the components in incompatible ways. So if you want to replace components with new parts (for example you wear out the drive train and you want to replace it), it can be difficult to find them. This puts you on an upgrade path, replacing everything so that it is all compatible again. However, bike manufacturers get steep discounts on components and it is almost always worth it to buy a brand new bike rather than upgrade all the parts of your old bike. Buying a fairly low-mileage used bike will only delay things for a while because eventually you will have to replace worn components.

Of course you can buy used components to replace your worn ones, but it is harder to asses the quality of the components unless they are attached to a bike. Also, there is a huge market for stolen goods and as a person who doesn't want their bike stolen, I also don't want to buy stolen goods. Used components are practically impossible to verify that they aren't stolen. Either someone is replacing the components because they are worn out (in which case you don't want them), or the components are stolen (in which case you don't want them) or the person is upgrading to new components before their old components wear out (very small number of people).

So basically, you are stuck with:

- Maintain your bike properly
- Ride it a lot
- Replace cheap worn compnents with new parts
- Buy a new bike when you get stuck in an upgrade path

(of course you never throw away the old bike because then you would have one less bike and who wants that???... so you upgrade it with new parts too... sell the car to pay for it since you are riding so much you don't need it anyway)

It's still ridiculous that they are portrayed as victims while Japan is portrayed as a "trap."

It's not like these men are refugees from Syria. They chose to come to Japan, they chose to stay, and the nature of Japanese society has never been a secret.

Most of their hardships are common sense. Surprise, surprise, career advancement in Japan often requires fluency in Japanese. And yes, supporting a family is generally pretty hard if you want to be a full time student.

A subset of foreigners in Japan make it their hobby to explain to why their lives are tough, but leave out the fact that they chose it.

Comparing bikes with lemons? Ugh.

Assessing value and quality is certainly a concern and a challenge for those who aren't bike geeks. I nearly bought a carbon framed bike from a woman in San Francisco a few years back, but I noticed a problem where the bond between one of the carbon seat stays and the steel dropouts had come loose (visible movement). She didn't even know about it and was bummed, I passed on the bike.

One place to take a first pass at bike prices (for many commercial bikes) is:

As for Craigslist, you have to be careful, many stolen bikes end up there.
