A random thought regarding copyrights...

So... Oracle's suit regarding the copyrights of APIs has been upheld by the SCOTUS...

a random thought entered my mind: The HTTP protocol may be considered an API and every access to some URL which causes code to be executed is an API... Perhaps Google could stop indexing all Oracle properties on the web because they could "fear" being sued for misappropriating Oracle's APIs and require that Oracle submit by postal mail a letter from their lawyers with permission to index a page, including the URL and SHA2 hash of each page where Oracle gives Google permission to copy for indexing purposes. Then Google will only list pages which matches the provided SHA2 hash.

Mucking around with ZooKeeper and Netty 4

ZooKeeper using Netty4 with a common netty worker pool...
Would be trivial to switch it to use the Netty 4 epoll implementation.

Now... To continue what I started hacking on ...

Global Internet Access

There appears to be a rash of billionaires announcing support for the idea of a global satellite-based internet service, for example: http://www.extremetech.com/extreme/197711-elon-musk-unveils-new-plan-to-circle-to-earth-in-satellites-for-fast-low-latency-internet

I would wager that if we have had good affordable internet in our first-world abodes, the wealthy would not be so inclined to think of such schemes. Like as like not, for a new third-party to compete on the ground is practically impossible due to legal red tape and so the space option becomes the most practical, in spite of being a bit inefficient. It's easy to imagine the Elon Musks of the world venting frustration about lack of coverage or simply being unable to cancel Comcast without losing sanity...

Of course, when the time comes, the legacy telcos will complain about unfair competition from these upstarts and will campaign for government hand-outs to help modernise their networks; something which they should already be doing instead of accumulating profit and giving the money to their directors and shareholders.

It will be curious to see what happens. Ideally, the telcos will see the light; otherwise, I won't lose any sleep as their networks decay into obsolescence.

Fox news Christian terrorists

Christian terrorist Jeanine Pirro, calling for a jihad/crusade to mass murder other people because other places which have tried mass murder worked out great.

I'm all for free speech except when it's threats, advocating violence or inciting violence.

Unlike the fox gaffe earlier this week, this is not funny.

Rowhammer: ECC DRAM by default?

Apparently, there has been a weakness in modern DRAM which had been known within the computing industry since 2012 which has been given name rowhammer. It is particularly the interesting because if how nearby memory locations have their bits flipped which violates the very foundation of our modern multiprocess systems.
Perhaps, it is time that all our PCs should have ECC memory by default which would at least fix single bit disturbances?

Some project foundation classes for Java.

Have been organising and repackaging some of my source code for release as free open source code. The flavour du jour is Java and these are just a few foundation classes which will be built upon in further packages, hopefully released soon (time permitting). #OpenSource #BSD #Java https://github.com/xiphis/xiphis-utils

Oh, how editing standards at The Guardian has fallen.

The Guardian posted this article, entitled: Women, beware this PUA army of sleazebags, saddos and weirdos by Hadley Freeman
"They’re sci-fi saddos; they’re World of Warcraft weirdos"
As someone who enjoys sci-fi and whose name is in the credits for more than one WoW game, this is inappropriate offensive mischaracterization. Some people are jerks because that is simply what they are and it has nothing to do with what fiction genre they enjoy or what computer games they have played.
I guess The Guardian is becoming just another sleazy tabloid with ineffective editors.
