Netflix Gets What It Pays For: Comcast Streaming Speeds Skyrocket

Warbothong Re:I Pay (324 comments)

1. You pay Comcast for Internet access at X speed.
2. Netflix pays Amazon and others for Internet access at Y speed ( http://en.wikipedia.org/wiki/N... )
3. You pay Netflix to send you movies via those lines that you both pay for.
4. Comcast holds your content hostage, wanting an extortion payment from NetFlix.

The point about NetFlix paying for bandwidth is important, since Comcast keep claiming things like "they shouldn't get a free ride" and "somebody needs to pay for the infrastructure", but they *were* paying for infrastructure; just not Comcast's (directly, anyway).

First Phase of TrueCrypt Audit Turns Up No Backdoors

Warbothong Re:A triumph for FOSS (171 comments)

This is why open source is so important.

How so? TrueCrypt is neither Open Source or Free Software. It's freeware (ie. proprietary).

Michael Bloomberg: You Can't Teach a Coal Miner To Code

Warbothong Re:Ability to design and write software... (578 comments)

Zuckerschmuck saying "teach them to code and everything will be great", then he really is clueless and out of touch. But, we knew that anyway.

More likely is that Zuckerberg, being at the top of an established pyramid, would love to see a huge influx of programmers into the job market.

Wages would come down, saving money for all established players. Average quality would also come down, making it more difficult for startups to disrupt the status quo.

It's the same as all this visa and lack-of-STEM nonsense.

Mathematical Proof That the Cosmos Could Have Formed Spontaneously From Nothing

Warbothong Re:"Proof" (595 comments)

Note that the words "could have" are used, which makes your point moot. They are not claiming that the Universe formed spontaneously from nothing, they are claiming that such claims cannot be refuted (yet). Or, alternatively, they're claiming that theories involving from-nothing Universes do not refute existing results; unlike, say, a theory which allows faster-than-light travel, which *would* refute existing results, and therefore have a much larger burden of proof (ie. it would have to be able to replace relativity).

Interviews: Ask Bre Pettis About Making Things

Warbothong Advantage over mass-production (69 comments)

What kinds of useful objects do you envisage being printed which aren't available from a local store? I've been following 3D printing for a while and have helped build a few machines, but the only objects I've seen printed are either purely aesthetic (eg. keyrings) or could be bought from a local shop in less time than the print takes.

Samsung Claims Breakthrough In Graphene Chip Design

Warbothong Re:Producing them is one thing (88 comments)

Producing them cheaply enough to rival chips made of processed sand is another matter entirely. Anyone remember gallium arsenide chips that were going to eat silicon for lunch back in the 80s? Yeah , well.... still niche.

To a first approximation, I'd say the cost of "applying sticky-tape to coal" isn't very different to "processing sand".

Gallium Arsenide, on the other hand, sounds complicated: http://en.wikipedia.org/wiki/G...

Canonical Shutting Down Ubuntu One File Services

Warbothong Re:Another Cloud Dispersal (161 comments)

The non-permanence of cloud services like storage and sharing is going to be hard to solve. Sure some will last. But some will not. How do you choose the ones the will?

By building a "Services as a Service" layer on top, which delegates the storage to whoever's still around.

Oblig. https://xkcd.com/927/

U.S. Court: Chinese Search Engine's Censorship Is 'Free Speech'

Ask Slashdot: What Do You Consider Elegant Code?

Warbothong Re:The pinnacle of elegant code (373 comments)

You may have been joking, but this one is fantastic: http://www0.us.ioccc.org/1988/...

It calculates pi by measuring the area of an ASCII circle, which is an incredibly direct encoding of the problem. Other than that there are two lines of supporting boilerplate and a couple of braces.

Is the Tesla Model S Pedal Placement A Safety Hazard?

Warbothong Re:Don't blame others for user error. (394 comments)

My advice to him would be to get an angle grinder and chop 0.3" off of the side of his foot to bring it to international safety standards.

That way, he can drive any car safely, without additional modifications to them.

Sorry, that's just the US code (you can tell by the imperial units). To qualify internationally, he needs to amputate 0.001 kilotoes.

Last Week's Announcement About Gravitational Waves and Inflation May Be Wrong

Warbothong Re:I think more people would be interested... (194 comments)

... in what caused or happened before the big bang.

I still can't believe we haven't sent an expedition to see what's North of the North Pole!

Last Week's Announcement About Gravitational Waves and Inflation May Be Wrong

Warbothong Re:Phase changes (194 comments)

I think phase changes on a universal scale is an amazing thing to ponder.

When we're talking about the moments after the Big Bang, a "universal scale" is actually quite tiny ;)

Back To the Moon — In Four Years

Unless it can pull in advertising revenue, it ain't happening.

It could definitely pull in advertising revenue. Just send a black guy, and use the slogan "BLACK to the Moon!".

Back To the Moon — In Four Years

Warbothong Re:Yeah, too bad there's no real reason to do so.. (292 comments)

The moon is a symbol, but there's no *practical* reason to go there, establish a base, a colony, or a really good restaurant.

Colonies are the reason. We need to get some of our eggs out of this Earth-shaped basket. Having a colony in Earth orbit is the easiest place to start, and the Moon is the easiest place in Earth orbit. It has gravity, so there's no need to tether everything like there is on ISS, and it has ground, which is a good source of building materials and momentum. Digging out a decently-sized lunar colony (robotically, or course) would be far easier than crafting the same size colony in free space.

Near earth orbital stations, in contrast, might be developed profitably for power stations, zero G manufacturing of exotic materials, ubiquitous satellite-based internet, and so on.

These are all short-term goals. They can (and arguably should) all be done right now, at small scale, on the ISS. They don't do anything to get us into space though; in fact they'd probably be better if all the humans involved stay on the ground.

The focus on the moon and Mars is just cold war era, retro silliness. We have limited resources to throw at space. This is the time to throw them at something that will give us some return.

We have limited resources *on Earth*. Space has its own resources. Some of them might be dropped down to Earth, but they're more useful up there.

Flies That Do Calculus With Their Wings

Warbothong Re:Time, distance, motion, acceleration (107 comments)

If fruit-flies use calculus then so do amoebas.

Rocks do calculus when they roll down hills, since they always make sure to only move a distance which exactly matches the integral over time of their velocity.

Circles do calculus too, since they always choose their area such that it corresponds to the integral over their radius of a circumference.

Pine Tree Has Largest Genome Ever Sequenced

Warbothong Re:Pine trees know how to make backups (71 comments)

More like the pine trees don't understand their genome properly, so they do a copy/paste before applying a mutation. They'd be less reluctant to refactor it in-place if only compilation didn't take so long.

Facebook Introduces Hack: Statically Typed PHP

Warbothong Re:I kinda want more specific types. (230 comments)

This can all be done with simple Classes, be my specific thought is that once the (pre)compiler is done with the extended type checking, it throws out all the overhead, and compiles to just using simple floating point variables. It's to catch programmer errors, not run-time errors.

This is the source of your problems: classes are not types. Classes are a bizarre mixture of bits of tagged unions, namespaces, free-variable scoping rules, typing, subtyping, polymorphism and pattern-matching. The worst part is that it's all first-order (eg. methods can't have methods), which forces higher-order concepts to be 'flattened out'. For example, static properties/methods, factories, controllers, etc.

If you tease these apart into separate things, and learn what each is on its own, you'll understand your code a lot more. In this case, float is a type, and types introduce no runtime overhead. Classes are not types, and they do introduce runtime overhead (extra memory for tags and extra runtime for dynamic dispatch).

Eff: A pure language with side-effects

Warbothong Warbothong writes  |  more than 3 years ago

Warbothong (905464) writes "The debate between pragmatism and purity in programming languages has been going on for decades. Pure languages forbid side-effects in their computations (eg. changing a variable), since they make formal analysis hard; whilst pragmatists embrace them to allow quick production of 'good enough' code. A new experimental language called Eff, created by Andrej Bauer and Matija Pretnar, is blurring this distinction. Eff is based on a Mathematical model of side-effects, allowing it to harness mutable state, exceptions, IO, random choice and more in a pure way from within a Python-like syntax. The product of on-going research, Eff is still in its infancy and, as its authors state, "...is an academic experiment. It is not meant to take over the world. Yet.""

Tiny generator runs off vibrations

Warbothong Warbothong writes  |  more than 6 years ago

Warbothong (905464) writes "Researchers at Southampton University in the UK have developed a tiny (less than 1 cubic centimetre) generator which uses local vibrations to output microwatts of power, making it an alternative to batteries, which need replacing regularly. The devices are currently being used in industry where "there is the potential for embedding sensors in previously inaccessible locations", but its creators imagine it could be used in devices such as pacemakers, where the beating of the heart would produce ample movement for the magnetic mechanism inside to work."

Warbothong (905464) writes "I am going off to University this month, so I have been chasing up payments and deposits, etc. online. The other day I received an email confirming that I am all payed up, which is great. The not-so-great part was the email's header, since after "To:" it had a list of 1343 email addresses, including mine. It is pretty clear that all of these addresses are for students paying their deposits online, and it is also clear that this list has been sent to 1343 people. In our world of datamining and spamming I am pretty concerned that sooner or later this list will get into the hands of someone who might want to make a bit of money from a list of 1343 valid email addresses, all in active use, all owned by soon-to-be students at a particular University in the UK who all have the capability for making online payments, so I am wondering what Slashdot readers make of this? Should I be worried? I have already sent an email of concern to the Reply-To: address, and got a swift response that this matter will be dealt with "immediately", but I am not sure there is much that can be done at this point. I would also like to point out though, that my email address is with Yahoo! and I have apparently already been added to at least two user's Buddy Lists. With that in mind, is this just a subversive way of getting fellow students together before we all leave for the campus, and to hell with the University's privacy policy and the fact that this was my spam-free email account?"
