EV Owner Arrested Over 5 Cents Worth of Electricity From School's Outlet

Gogogoch Very, very dangerous - run away power draw (1010 comments)

The school is very, very luck to have stopped this power drain so early. At a rate of 1kW/hr, the car would have drawn 2kW by hour 2, and 10kW after 10 hours. This is very dangerous - to have an energy draw that is accelerating!

Why oh why didn't they design a car that just draw 1kW? You know, as in 3600 kJ/hour? That would be much more sensible.

Having an accelerating power draw - 1kW/hr - is a recipe for disaster. Explosions and stuff.

How an Astronaut Falling Into a Black Hole Would Die Part 2

Gogogoch Re:So what should the family do? (263 comments)

I disagree. This is why we have elevators in buildings, and not just ballistic platforms that fire you up to the required floor. Much easier, and safer, to overcome the local gravitational force (Sun = 27x Earth's field) and move smoothly away.

How an Astronaut Falling Into a Black Hole Would Die Part 2

Gogogoch Re:So what should the family do? (263 comments)

I believe that with shields and a structural integrity field you are fine, and of course warp drive will get you out because it is FTL. Below the mundane event horizon, however, and closer towards the singularity, there is the sub-space event horizon and even your warp drive will not help you there.

I have all this on good authority - must be true.

How an Astronaut Falling Into a Black Hole Would Die Part 2

Gogogoch Re:So what should the family do? (263 comments)

blackholes are very helpful holding galaxies together

Yes, but the mass of the black hole would equally well hold the galaxy together even if it was more usefully organized - solar systems and planets etc. From the rest of the galaxy's perspective, it doesn't care what's down in the well so longer as there is something. So there is some argument to say that black holes are the least helpful form of matter from our solipsist point of view.

And anyway, isn't it a huge mass of dark matter that actually holds everything together?

How an Astronaut Falling Into a Black Hole Would Die Part 2

Gogogoch Re:So what should the family do? (263 comments)

You are forgetting length dilation in the moving frame of reference, and so have it all wrong. Length and time dilation have the same Lorentz transformation factor, so you can either think of it as time moving more slowly for the traveller from the outside viewer, or the distance being shortened from the traveller's perspective. Either way, the traveller could make the trip in 10mins with sufficient velocity/energy, as the original commenter said.

Physicists Create Quantum Link Between Photons That Don't Exist At the Same Time

Gogogoch Re:Wait for the retraction (364 comments)

I doubt this is BS, sounds authentic to me. Quantum mechanics is weird. As for the "outside ... space and time", note that the missing words from TFA are "outside everyday notions of space and time". In other words, outside our common sense.

UK Court: MPAA Not Entitled To Profits From Piracy

Infringement itself is not criminal; it is a civil matter between the infringer and the copyright holder. Under some DMCA legislation in various countries breaking a digital lock makes you a criminal.

Are Graphical Calculators Pointless?

Are Graphical Calculators Pointless?

Gogogoch Yes, pointless. (636 comments)

Yes, graphical calculators have always been a gimmick, and completely pointless.

Professionals in engineering, science, or finance never use these things. A scientific or financial calculator, a spreadsheet, and possibly MATLAB are all you need.

CMU Eliminates Object Oriented Programming For Freshman

Gogogoch Re:Finally! (755 comments)

They are all huge broken OO designs! At least, that is my experience.

The original architect considers the domain - usually poorly since he/she is only human - and says "lets have an OO structure that looks like this". And with the first enhancement request the OO design breaks because the designer thought the world worked in a different way and enshrined that thinking in to the OOD.

OO almost always turns out to be an impediment. I once inherited a project that had been a poster-child for OOD, where the architect had innovated with "design patterns". OMG. Compared with similar projects of similar complexity, this particular project ended up costing about 100% more, or $20M, and was of course massively late.

I like your comment about "thinking about OO problems". Could we say OOD is software engineering for software engineering's sake? Oh, and for the worthies who sell books and CASE tools?

You are not alone!

CMU Eliminates Object Oriented Programming For Freshman

Gogogoch Finally! (755 comments)

OO is fine in theory but, oh dear, what a mess in reality. I would love to know how much OO has negatively impacted software development over the year. Find a disastrous project and I'm sure there will be a whole load of OO there boggling the mind. The problem is that the object design at the start of the project typically has no bearing on the model after some years, and the cost of redesign and refactoring over and over is terrible. And don't get me going on design-patterns! Lets take OO and move it beyond the whit of man, or at least 90% of developers.

OO is fine for small-scale objects, like UI widgets. Or very large container objects. But in between, oh my god.

Now I know this will be flame bait for a lot of slashdotters, but only because you have been brainwashed into thinking OO is good. Like how physicians thought blood letting was essential to balance the humours 200 years ago, but now viewed as a relic from the dark ages.

No, the answer is not assembly code either (even though I still have my 6502 hex codes by heart).

Scientists Decipher 3-Billion-Year-Old Genomic Fossils

Gogogoch Re:Wait, what? (217 comments)

"All current life was set in place nearly three billion years ago". Absolutely not - your view of the history of biology is very warped. Study more biology itself to realize what 'current life' actually looks like. Some important points:

1.7~2 Billion years ago: probable endosymbiosis of prokaryote into eurkaryotic cells, forming mitochonria. Much later than the 3 billion years you suggest, and an absolutely vital stage in the evolution of multicellular life. In fact, it is suggested that the emergence of mitrochondria is why we are here to day - without these powerhouses single-celled life did not have enough available energy to form multi-cellular organisms.

1~1.3 Billions years ago: complex multi-cellular life: While the diversity, resilience, and ubiquity of single-celled life is amazing, I find complex multi-celled life much more astonishing. That colonies of cells can cooperate, specialise and form complex life is a wonderful achievement of evolution. Of course, it took a mind-boggling amount of time. Still, a significant step the results of which are quite distinct from life of 3 billions years ago. So your assertion is again inadequate.

~600 million years: emergence of the first neuron.

~580 million years: nerves and muscles, working together; first eyes

~550 million years: brains

And so the list goes on. Perhaps a significant development every 10-20 million years.

~540 million years: hearts and circulatory systems

There is a giant change from single-celled life to cats, dogs, and humans. What you should be saying is that, as a programmer, you are amazed that all life on Earth has the same genetic code - that the 3 base-pair codon is almost universal in every cell and organism on the plant. I suppose I do like you perspective though, when you look at a yeast cell, an oak tree, and a human and realise they are all related, all cousins, all derived from an evolutionary chain billions of years in the making.

Massachusetts Bids To Restrict Internet Indecency

The reply above is not "Troll", please mod up.

Kids of 8 and 10 are quite happy to play in those type of website. How can the other poster be so insulting and haughty considering that these websites are fascinating and interactive (for that age) and designed to suck kids in. The poster clearly has no experience with young kids.

First cloned human embryo created from skin cell

Gogogoch Gogogoch writes  |  more than 6 years ago

Gogogoch writes "New Scientist is reporting that cloned human embryos has been created from skin cells for the first time, a breakthrough in cloning technology. This development opens possibilities for developing stems cells from your own tissue — leading to all manner of new treatments from spinal cord injuries to replacement organs. Starting with skin cells donated by two men and eggs donated by three young women undergoing fertility treatment, they made each embryo by fusing the nuclear DNA from a skin cell with an egg emptied of its own nuclear DNA. Not to mention applications regularly seen in science fiction..."

How did RIM's Blackberry get FCC clearance?

Gogogoch Gogogoch writes  |  more than 6 years ago

Gogogoch (663730) writes "I'm sure there is an expert reading Slashdot who can tell us how RIM got their Blackberry approved by the EMC regulators, such as the FCC. I'm thinking of the "does not interfere with other equipment" requirement. My experience is that a Blackberry manages to interfere with most forms of telephone, speakerphone, or audio amnplifier producing those annoying clicks and noises something like a 56K modem, but different. Please, how did they get away with it?"
