Comment Is that /. news? Really? (Score 1) 162

I mean c'mon, most of the community know that the moron lie to his people all the time.

Eventually he won't be able to hide the truth when access to communication will be more and more easily available and his "realm" will eventually revolt and head straight into a civil war. But until then, he could blather he fucked the president dog to show dominance for all I care.

Comment Re:Reasons why I don't like Musk's hyper loop (Score 1) 124

1. All the diagrams give the impression that it will be like people flying through tubes as in Futurama. Instead you will be sealed inside a metallic "bullet", that runs in a metallic tube - no windows for you (sort of like James Bond in The Living Daylights). It's a pity if you have any sort of claustrophobia.

If you dislike the idea of long-range transportation without windows, I have bad news for you...

2. While the device doesn't run in a complete vacuum, it runs in an atmosphere that is low to the point of being unbreathable. But the device doesn't contain any onboard air supply - instead it relies on the driving compressor/fan assembly to compress the air to a human sustainable amount. So if the device loses power for any reason (electrical, mechanical, computational) then you better be able to hold your breath for a long long time.

Really? Are you seriously so close-minded to think of this as a problem? I guess you got this idea by taking airliner as reference which is simply dumb. The reason why airliner need onboard air supply is because there's not air available in case the cabin pressurisation fail. But in Hyperloop case, engineering emergency exit system seem far more logical than oxygen mask.

3. There was no indication that the loop itself was anything more than a single tube. Thus there is no capability to bypass any section. So if a device fails, all devices that are already in transit and behind it are screwed (see 2 above).

Yeah...if they ever present a working prototype, I'm sure they'll simply "forgot" to address safety issue like "what will happens if the Hyperloop fail (or hit an iceberg) in the middle of the desert?"

Submission + - Notepad++ Leaves SourceForge (notepad-plus-plus.org)

An anonymous reader writes: SourceForge was a good place; unfortunately, sometimes good places don't last.

Recently SF hijacked its hosted projects to distribute their wrapped crapware:

        SourceForge grabs GIMP for Windows' account, wraps installer in bundle-pushing adware
        Black “mirror”: SourceForge has now taken over Nmap audit tool project
        What happened to Sourceforge? The full story between VLC and Sourceforge

Obviously, the paid component per installation system is one of their important income generating scams. I would be fine with that, if they were the actual owners of the legitimate software. The real problem is, they are polluting these open source software installations for the purpose of filling their pockets by this scam, and worst of all, without even notifying the authors/creators of this software, while the creators are struggling against such parasitic software in order to keep their installers cleaner and safer.

Such a shameless policy should be condemned, and the Notepad++ project will move entirely out of SourceForge.

I humbly request that Notepad++ users not encourage such scams, and educate others not to download any software from SourceForge. I request as well that the project owners on SourceForge move out of SourceForge, in order to preserve the purpose of the Open Source Community and encourage the works of true authors/creators.

Submission + - Philae comet lander wakes up (bbc.com)

techtech writes: "The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth.
Philae, the first spacecraft to land on a comet, was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November.
It worked for 60 hours before its solar-powered battery ran flat.
The comet has since moved nearer to the sun and Philae has enough power to work again, says the BBC's science correspondent Jonathan Amos.
An account linked to the probe tweeted the message, "Hello Earth! Can you hear me?""

a lot of parachute issues are deployment problems at speed/ heat.

Take a spacecraft which is flying at thousands of MPH toward the ground, burning at 2000 degrees, and then deploy a soft fabric.

If you don't unfold it perfectly you lose everything. if one strand of folding rope is out of place you lose everything. The amount of engineering going into just the folding of a parachute would surprise you.

Yeah, about this...

Why is it so hard to develop a control unit to unfold the parachute? I know it's been used thousand time with success already but is there no other way than blowing up the cover and throwing that big ball of parachute and hoping it will unfold perfectly? (Yes, I know it's more controlled than that, but you get my point)

The thing everyone always ignores is that no matter what, eventually your brain dies. Whether in you or after you've been uploaded to a computer or another brain or what have you. And when that happens *THAT* you is dead. *YOU* still experience the pain of death. YOU still cease to exist. There is something out there with your memories and thoughts, but they are not you any more than a photo album or journal is you.

The thing that everyone like you always ignores is that no matter what, cells are always dying. Constantly! Even brain cells! And then they get replaced by other cells! But that doesn't mean you cease to be you.

Exactly this!

That thought came to my mind a while ago. Eventually, our whole brain replace itself but we never cease to be, well, ourselves. Even though it's a generally accepted concept in /. community that our mind is our brain (and not our soul or anything religion related), it's mind blowing to think that I'm still myself even if our brain replace itself every 7 years (or 10 depending on the research). Or is my being is slowly disappearing to be replaced by perfect copy of myself and the memory of my past is actually the remain of my old self?

It's a complex but very fun concept to play with, but it's also quite terrifying sometime.

How is that energy stored initially? Giant capacitor banks, or flywheel to generator?

IMHO, it'll depend on many things. How much weight or space is an issue for carrier? What's the hazard if that storage is hit? How many backup is needed? Is operating life or ease to replace important? And we're not talking military grade equipment neither which I'm not very familiar with.

Whenever they think of, I guess it's gonna be a similar tech the navy have developed for their railgun : https://www.youtube.com/watch?.... And, according to my quick google search, it seem they are using Lithium Iron Phosphate battery technology.

Steam seems like an ideal solution to me. Steam expands so well the dynamic range of it's force curve seems apropos to the task. How much of the EM energy goes into force? surge currents and magneto striction are usually things people find shorten the lifetime of electo devices yet here they are at the extreme in these. Presumably there's no shortage of steam available and it's a great way to store energy.

Really? My intuition is completely the opposite. Steam may expands well in the dynamic range but electricity will do anything it's controlled to. Want an exponential acceleration? Linear? Sinusoidal? You name it.

With sectorization and a few feedback control unit, it seem to me that you could precisely and instantly control the power transmitted into the catapult anywhere along the ramp. You could also drastically change the speed if needed, also something that doesn't seem as easy with steam. You since those carrier are nuclear-powered it take way less space than a whole steam system.

But, since my field is electrical engineering, I guess my opinion is a little biased.

Comment Here's a few idea (Score 1) 557

At first I would think about a pipe complex in the structure of the house so I could easily wire anything anywhere. But with the future going more and more wireless (even charging battery), it could become obsolete in a few year.

A few other idea are power outlet with USB and wireless power meter, wireless locking system, LED light bulb, smart thermostat, Solarcity's photovoltaic system with Tesla Battery, camera and security system connected to the network (and your cellphone) if your neighborhood isn't completely safe and finally a strong network paired with "Google fiber" like internet.

FTFY

It's the growing popularity that made the modding community, not the inverse. As long as you got your fanbase and your game is mod-friendly it should work out. And AFAIK, LEGO have a freaking huge fanbase (and most of them are playing minecraft right now).
