Language matters.
Instead of cyclists, people biking. Instead of accident, collision. Instead of cycle track, protected bike lane.

Study finds that girls score poorly at high school maths due to prejudice, rather than lack of ability.

Shame on Schneier  Everyone wants to own you and Schneier thinks the owners will win because people are evil and lazy.  What a disappointing turn around from his Eben Moglen interview where he told us that companies that had violated us must never be trusted again.  

It is also disappointing to see him painting Facebook and Google with the same brush.  Don't be evil is not at all the same motto as they trust me, dumb fucks.  It may be true that Google was forced into betraying their customers but that kind of betrayal is the business model of other companies.  Not keeping track of details and easy cynicism is simply lazy.  Schneier should be ashamed of that and even more ashamed of projecting it onto others.  

Finally, Schneier has overlooked the obvious solution available with free software.  People can help themselves and their neighbors without the assistance of massive companies who's business is mostly to screw people.  We can have honest hardware and the folks at the local computer store can make it work for us better than Microsoft ever did.  Better bandwidth and networks come from getting rid of the bullies too.
 
Everyone Wants You To Have Security, But Not from Them https://www.schneier.com/blog/archives/2015/02/everyone_wants_.html

"...there are lots of people who want you to be secure against everyone but them. And that includes all of the major computer manufacturers who, roughly speaking, want to manage your computer for you."

Do be sure to read the whole thing if you have time.

"Don't be evil" was once the motto, but they haven't lived up to that in many years.

and so, my stream changes.  
 
You can never step in the same river twice

People say this remark is from Heraclitus.  The main idea is that the river keeps changing as the water flows.  The other idea is that you keep changing, too! 

Jorge Luis Borges wrote:

… each time I recall fragment 91 of Heraclitus, "You cannot step into the same river twice," I admire his dialectical skill, for the facility with which we accept the first meaning (“The river is another”) covertly imposes upon us the second meaning (“I am another”) and gives us the illusion of having invented it…

But actually it seems Heraclitus didn't exactly say "you cannot step into the same river twice".

He lived roughly from 535 to 475 BC. Only fragments of his writings remain. Most of what we know about him comes from Diogenes Laertius, a notoriously unreliable biographer who lived 600 years later. 

For example: Diogenes said that Heraclitus became sick, tried to cure himself by smearing himself with cow manure and lying in the sun... and died, covered with poop. 

But Diogenes also said that Pythagoras died while running away from an angry mob when he refused to cross a field of beans, because beans were sacred to the Pythagoreans.  And Diogenes also said Pythagoras had a golden thigh - and was once seen in two places at the same time.

So we don't really know much about Heraclitus.  And among later Greeks he was famous for his obscurity, nicknamed “the riddler” and “the dark one”.

Nonetheless a certain remark of his has always excited people interested in the concepts of sameness and change.

In one of Plato's dialogs the Socrates character says:

Heraclitus is supposed to say that all things are in motion and nothing at rest; he compares them to the stream of a river, and says that you cannot go into the same water twice.

This is often read as saying that all is in flux; nothing stays the same. But a more reliable quote passed down through Cleanthes says:

On those stepping into rivers staying the same other and other waters flow.

That's harder to understand - read it twice!    It seems that while the river stays the same, the water does not.

No matter what the details are, to me Heraclitus was trying to pose the great mystery of time: we can only say an entity changes if it is also the same in some way — because if it were completely different, we could not speak of "an entity" that was changing.

Of course we can mentally separate the aspect that stays the same and the aspect that changes.  But we must also bind these aspects together, if we are to say that "the same thing is changing".

In category theory, we try to swim these deep waters using the concept of isomorphism.   Very roughly, two things are isomorphic if they are "the same in a way".  This lets us have our cake and eat it too: two things can be unequal yet isomorphic.

So when you step in the river the second time, it's a different but isomorphic river, and a different but isomorphic you. 

And the isomorphism itself?  That's the passage of time.

So, isomorphisms exhibit a subtle interplay between sameness and difference that may begin to do justice to Heraclitus.

None of these thoughts are new.  I'm thinking them again because I'm writing a chapter on "concepts of sameness" for Elaine Landry's book Category Theory for the Working Philosopher.  You can see a list of chapters and their authors here:

https://golem.ph.utexas.edu/category/2015/02/concepts_of_sameness_part_1.html

Here and in future articles you can watch me write my paper, and help me out.  It'll be more technical - and I hope more precise! - than my remarks here.  But it's supposed to be sort of fun, too.

In Part 2, I talk about the Chinese paradox "when is a white horse not a horse?":

https://golem.ph.utexas.edu/category/2015/02/concepts_of_sameness_part_2.html

In Part 3, I ask if you've ever used the equation x = x for anything.  And I pose a precise conjecture which claims that this equation is useless.  I would like someone to settle this conjecture!

But if x = x is a useless equation, why do mathematicians think it's fundamental to our concept of equality?

The picture here is taken from someone on G+ who is vastly more popular than me:

"submerged in water" seems pretty unlikely. is a very different environment from simply "100% humidity" in the air.

Lawmakers are poised to introduce a bill to Fast Track anti-user deals like the Trans-Pacific Partnership through Congress. If you're in the U.S., you can help us stop them by contacting your representatives or tweeting at congressional leaders to oppose and speak out against this plan.
The Trans-Pacific Partnership (TPP) talks are stalling while the White House assures its trading partners that this secret trade agreement won't be amended when it comes back to Congress for ratification after the President signs the deal. That's why the Executive is scrambling to get its allies in Congress to pass Fast Track. If they succeed, the U.S.

EFF's Decentralized SSL Observatory has uncovered possible evidence of man-in-the-middle attacks against Superfish/Komodia/PrivDog users--but there's no way to know for sure.
Over the past week many more details have emerged about the HTTPS-breaking Superfish software that Lenovo pre-installed on its laptops for several months. As is often the case with breaking security incidents, most of what we know has come from security engineers volunteering their time to study the problem and sharing their findings via blogs and social media.

If we let ISPs do what they want, they will bring us back to networks like Prodigy or AOL.  
#NetNeutrality I very clearly remember what the Internet was like for me back when I was on dialup. I was on Prodigy, and I had access ONLY to Prodigy pages, Prodigy groups, and Prodigy services. I ONLY interacted with Prodigy users. For me, the entire internet was comprised of Prodigy. Oh, sure, I was aware that there were other internet providers, but they were closed off from me. I found out about the World Wide Web, but it was an abstract, di...
