Comment Re:Emacs, vi, IDE (Score 1) 359

Depends on whose code I'm editing.

If it's my own, then emacs.

If it's someone else's, then usually vi since I'm probably in a hurry.

IDEs I play with every once in a while, but invariably I hit some silly brick wall where it's better/faster/dareIsayeasier to bring it up in emacs.

I have been using notepad++ on Windows a lot lately, and just wondering what the closest thing to that there is on Linux. It's the only thing I've seen that combines the feature set of emacs with the snappiness of vi while still having a pretty consistent GUI. I have to admint I learned a lot about what emacs can do by discovering features and plugins in notepad++ and Googling how to do that in emacs :-P (speedbar, whitespace-mode)

Sublime Text editor was a lot of fun to play with if only for the multi cursor mode, but there's a great howto on doing the same thing in emacs.

Eh, all good points.

I think the mistake was just in making it a heavy-handed ban. Bringing out the ban hammer just turned it into a joke.

I'm sure they will successfully reintroduce the behavior-modification measure by creating a higher sales tax on large drinks. Which will probably have an as good or better impact as a silly ban that people would gladly find ways to circumvent just to "stick it to the man".

We have these luxury taxes on alcohol that corresponds to the proof (one tax bracket for wine and beer, another for hard liquor). It could certainly work like that, and not come across as freedom-limiting nanny-statism.

Submission + - Surgical Snakebots Are Real, And Heading For Humanity's Orifices (popsci.com) 1

malachiorion writes: Last week marked the first use of a surgical snakebot—the Flex system, from MA-based Medrobotics—on living human beings. It wriggled down two patient's throats, to be specific, at a hospital in Belgium. That's neat, and could mean an interesting showdown-to-come between this snake-inspired robot (invented by a Carnegie Mellon roboticist), and the more widely-used da Vinci bot. But this is bigger than a business story. The next era in general surgery, which involves making a single small incision after entering the anus or vagina, instead of multiple punctures in the abdomen, might finally be feasible with this kind of bot. This is my analysis for Popular Science about why instrument-bearing snakebots wriggling into our orifices is a technology worth rooting for.

Submission + - Is Suspension-Energy Recovery The Next Big Thing?

cartechboy writes: Let's face it, regenerative braking is now old tech. It's on everything from the Toyota Prius to your mom's new Ford Fusion Hybrid. So what's next? We've already heard about thermoelectric technology which recovers energy from hot surfaces such as exhaust, but what about the energy used by your car while moving up and down? That's right, recovering energy normally lost through a vehicle's suspension. Audi is reportedly developing a regenerative suspension system that could reclaim energy in a similar way to regenerative braking, providing an extra boost of electricity from the up-and-down motion of the shock absorbers. Shocks can become quite hot, especially on a bumpy road. That heat is pretty much wasted as it dissipates into the atmosphere as wasted energy, but the Audi system would collect it with an attached generator. That recovered energy would be stored in batteries and used to power a hybrid's electric motor or electrical accessories in a conventional car. Audi hasn't said when this tech will make its public debut, but this stuff is the next step in when it comes to energy recovery in cars.

Submission + - Evidence Of A Correction To The Speed of Light

KentuckyFC writes: In the early hours of the morning on 24 February 1987, a neutrino detector deep beneath Mont Blanc in northern Italy picked up a sudden burst of neutrinos. Three hours later, neutrino detectors at two other locations picked up a second burst. These turned out to have been produced by the collapse of the core of a star in the Large Magellanic Cloud that orbits our galaxy. And sure enough, some 4.7 hours after this, astronomers noticed the tell-tale brightening of a blue supergiant in that region, as it became a supernova, now known as SN1987a. But why the delay of 7.7 hours from the first burst of neutrinos to the arrival of the photons? Astrophysicists soon realised that since neutrinos rarely interact with ordinary matter, they can escape from the star's core immediately. By contrast, photons have to diffuse through the star, a process that would have delayed them by about 3 hours. That accounts for some of the delay but what of the rest? Now one physicist has the answer--the speed of light through space requires a correction. As a photon travels through space, there is a finite chance that it will form an electron-positron pair. This pair exists for only a brief period of time and then goes on to recombine creating another photon which continues along the same path. This is a well-known process called vacuum polarisation. The new idea is that the gravitational potential of the Milky Way must influence the electron-positron pair because they have mass. This changes the energy of the virtual electron-positron pair, which in turn produces a small change in the energy and speed of the photon. And since the analogous effect on neutrinos is negligible, light will travel more slowly than them through a gravitational potential. According to the new calculations which combine quantum electrodynamics with general relativity, the change in speed accounts more or less exactly for the mysterious time difference. Voila!

Submission + - US releases memo justifying drone strike on American citizen (theverge.com) 1

schwit1 writes: Under orders from a US appeals court, the Obama administration has released a memo justifying the killing of American citizens with a targeted "drone strike." The memo presents a case for killing Anwar al-Awlaki, an al-Qaeda propagandist who was killed in Yemen in 2011. The strike on al-Awlaki has been widely debated since then, especially after a separate attack inadvertently killed al-Awlaki's 16-year-old son Abdulrahman. Now, thanks to a Freedom of Information Act request made by the ACLU and others, it's possible to read both the court's reasoning and the 30-page legal debate on whether he and others could be killed without due process under the CIA's drone program.

Yeah, with enough hand waving, anything is plausible. You could have something in between a low energy transfer on the http://en.wikipedia.org/wiki/I... and waiting lots of time, or some kind of slingshot, or just burn fuel to do simple transfers between orbits. But I guess since your propulsion is on all the time for artificial gravity, you're kinda doing a propellant-assisted slingshot. The slingshot does require the planets and the sun have to be lined up just right, so it does make sense that the company wants to depart early and use more fuel on a longer journey, because they wouldn't get as much gravitational assist if they had waited a week for Venus and the Sun to be in a better position relative to the source and destination.

Sad, though, I remember when I used to hit freshmeat.net as much as slashdot.

I am glad, though, that I got a good chunk of my life back when I learned to just rely on aptitude to keep stuff on my system updated for me.

Still, I ought to go and compile a kernel for the heck of it though, for old time's sake.

Submission + - FLIP - US Navy's Oldest, and Most Unusual, Research Vessel 1

stephendavion writes: US Navy maintains a research vessel that is designed to be capsized vertically. As a result, most rooms on it have two doors: one to use when the ship is horizontal, another when vertical. Commonly referred to as the FLIP (Floating Instrument Platform) ship, it is actually a 355ft long, spoon-shaped buoy which can be flipped from horizontal to a vertical position by pumping 700t of seawater into the 'handle' end whilst flooding air into the 'cradle', causing it to rise up out of the sea. Once the 28 minute transformation from horizontal to vertical has taken place, 300m of the buoy are submerged underwater, keeping the 700 long-ton mass steady and making it perfect for researching wave height, acoustic signals, water temperature and density, and for the collection of meteorological data.

Submission + - Are U.S. Hybrid Sales Peaking Already?

cartechboy writes: The Toyota Prius is pretty darn popular, especially in California. One might think that hybrid sales are on the rise as gas prices continue to fluctuate, but it seems hybrid sales in the U.S. might be peaking. Researchers at IHS Automotive found that U.S. hybrid sales haven't kept pace with the rest of the market. In the automotive world, conventional wisdom states that adding a model to a brand or segment will increase sales--but that hasn't happened with hybrids. The number of hybrid offerings has almost doubled from 24 in 2009 to 47 in 2014--but U.S. hybrid sales haven't dramatically increased. In fact, hybrid market share actually declined from 2009 to 2010, and then again from 2013 to 2014. So if consumers aren't buying hybrids, what are they buying? It seems some hybrid early adopters are now switching to plug-in hybrids or electric cars stating that these models are just nicer to drive. Is this already the beginning of the end in some way for hybrids, or is it merely a blip on the sales chart?

How was it that the main character had such terrible Russian voice acting, whereas all the other Russians and even the Thai prostitute had more authentic accents? That was another thing that sort of drove us up the wall about GTA4 :P

OK, I'll say something nice about GTA4... I did get a chuckle out of the achievement tracking for flying things under bridges... that was something missing from most flying games :P
