Stanford Team Creates Stable Lithium Anode Using Honeycomb Film

Twinbee Re:Every month a new battery breakthrough, but.. (117 comments)

mAh only tells half the story. You need the voltage in combination to determine the true energy capacity of the battery. Ideally we're looking at the 'watt-hour'. Only in a world where the voltage stays the same in all devices and conditions does it make sense to talk about amp hours as if that was the total energy.

Japan To Offer $20,000 Subsidy For Fuel-Cell Cars

Twinbee Re:Why isn't the U.S. doing things like this? (156 comments)

I think the battery is more like $20k to 30k. I also think the battery will last a LOT longer than 5 years.

Here's a couple of ideas how long:
0.5% battery loss after >30K miles: https://www.youtube.com/watch?...

93% after 75K miles:
http://www.reddit.com/r/teslam...

I'd be happy going down to say 50% (assuming 200 mile range). I do around 10,000 miles each year, so doing the math, it'll take me over 500 years before I replace the battery. Okay, the sheer lifetime degrades the battery too, but I doubt it will kill it before say, 50 years.

An MOT is just something in the UK we need to have yearly so that a car is legal to drive on the road.

I hope you will now consider that batteries really have improved greatly, and can only better.

Japan To Offer $20,000 Subsidy For Fuel-Cell Cars

Twinbee Re:Why isn't the U.S. doing things like this? (156 comments)

> nobody cares about mathematical efficiencies.

You're right there, but they will care about fuel cost - could be up to 5x cheaper to go with electricity for the same mileage.

> you know what people do care about? range and convenience time.

I agree. It's just as well then that Tesla's Model S can do 200-300 miles, and their cheaper $35,000 Model 3 (due out 2017) will do around 200 miles.

You want convenience? How about an MOT every 5 years instead of every year? EVs are incredibly simple, and have very few moving parts. They're as close to a solid state device as you're gonna get. Wouldn't surprise me to see the Teslas going for more than 50 years with very little servicing to speak of (apart from tyre changes, and window wipers).

The First Person Ever To Die In a Tesla Is a Guy Who Stole One

Twinbee Re:Unsafe at any speed (above 100 MPH)... (443 comments)

Okay, fair enough.

But then going back to my original point, if it takes the same energy to accelerate... *in space* ...from 0 to 10mph as it does from 90 to 100mph, then aren't we creating more energy than we put into the system by crashing? What gives?

Leaked Build of Windows 9 Shows Start Menu Return

Twinbee Right, no Aero glass? (346 comments)

And how about Aero Glass? Do we get that back too?

I don't want spartan overly minimalist buttons, windows and dropdowns that hinder more than they help. I want delineated areas that indicate boundaries with beveled widgets that say "click me". I also don't want white-washed backgrounds that strain the eyes when I'm trying to work productively - I want various shades so I can see that the menu, taskbar or URL bar is not part of the main page.

Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best

Twinbee Re:Ideal PPI (129 comments)

Anti-aliasing is a hack that complicates things for a few reasons:

1: Anti-aliasing may look smoother but it also looks more blurred than non-antialiasing. That's why I based my test on no anti-aliasing.

2: If Apple isn't do it, then it must be at least somewhat inherently tricky to get right. And at the least it breeds bugs. Kludges usually breed bugs somewhere down the line as a rule of thumb.

3: Anti-aliasing complicates the OS (such as using Cleartype which has to be adjusted for every monitor it comes across etc.). Taking a screenshot and zooming in on the anti-aliased bits produces colour fringing.

4: Anti-aliasing complicates paint and word-processing software which has to take into account the techniques necessary for smooth line and curve drawing. Additionally, try filling in an area in paint software; anti-aliasing is not your friend.

5: Certain pictures with anti-aliasing use more colours, and eat up more memory as a result, especially when compressed in PNG format. A black and white picture uses 256 colours when it should use two. A colour picture..... well, the sky is the limit.

6: Scaling is much faster/simpler when you can do it the easy, and not to have worry about averaging neighbour pixels. Need I go on?

I think that's a very good point, and something I considered too. I'm not sure that would work for ever-increasing brightnesses though.

Twinbee Ideal PPI (129 comments)

SO...... if you paint a white single-pixel width 15 degree line without any anti-aliasing onto a black background, what does the PPI need to be at so you don't notice any jaggies?

300? 600? 1200? 2400 or more?

Windows is a lot more complicated than a hardware interface specification, so MS deserves a little more to hold the rights to the Windows and its technology. But I get your point.

New Microsoft CEO Vows To Shake Up Corporate Culture

Twinbee Re:Manager (204 comments)

All fair points but...

so if you buy a new camera/scanner/mouse/keyboard/whatever, you can't plug it in to your current USB socket, and need to pay another $100 to get the new socket

Microsoft have done a lot to support backwards compatibility. Most software which works on WinXP will work on Win 8 and vice versa.

I don't think the price MS charges for Windows is amazingly extortionate, but I get your point.

As you semi-pointed out, if MS opened up Windows I fear we'd get the same fragmentation Linux/Unix has. That's the last thing we need. Standards are good, fragmentation is not. (As long as the product is mature/good quality, and competition isn't needed as much).

New Microsoft CEO Vows To Shake Up Corporate Culture

Twinbee Re:Manager (204 comments)

Yes there is. It takes a lot of effort to design say, a generalized GUI API that will work on all OSs, and after all that effort, it won't be as optimized as if it was specially written to take advantage of anything in the Windows OS. Not that I like Windows OS particularly (I hope Ubuntu takes off), but I dislike the mess that is non-standardization even more. Bloat is bad also.

USB sockets also lock you in to using USB leads.

The First Person Ever To Die In a Tesla Is a Guy Who Stole One

Twinbee Re:Unsafe at any speed (above 100 MPH)... (443 comments)

Interesting. I'm confused now.

To simplify, let's assume it's in space. To go from 0 to 10mph (relative to a stationary object, say a satellite near Earth) surely requires as much thrust, as going from 90mph to 100mph. In fact relative to the position of the sun, it's like comparing 67,000 mph to 67,010 mph with 67,090 to 67,100, which works out about the same in energy requirements. But relative to the Earth's satellite, and according to your kinetic energy equation, that'd be a massive difference in energy required (0-10mph versus 90-100mph).

Just out of interest, if it takes the same energy to accelerate from 0 to 10mph as it does from 90 to 100mph (assuming zero wind resistance), then aren't we creating more energy than we put into the system by crashing? What gives?

YouTube Introduces 60fps Video Support

Twinbee Something has frozen over. (157 comments)

Hell has frozen over. I've been anticipating standard 60fps support on Youtube for years and it's finally come. My bitterness is gradually fading...

I wonder if existing videos at 60fps already on Youtube will be adjusted to support the feature.

The Insidious Creep of Latency Hell

Twinbee Twinbee writes  |  more than 3 years ago

Twinbee writes "Gamers often find 'input lag' annoying, but over the years, delay has crept into many other gadgets with equally painful results. Something as simple as mobile communication or changing TV channel can suffer. Software too is far from innocent (Java or Visual Studio 2010 anyone?), and even the desktop itself is riddled with 'invisible' latencies which can frustrate users (take the new Launcher bar in Ubuntu 11 for example). More worryingly, Bufferbloat is a problem that plagues the internet, but has only recently hit the news.

Half of the problem is that it's often difficult to pin down unless you look out for it. As Mick West pointed out: "Players, and sometimes even designers, cannot always put into words what they feel is wrong with a particular game's controls.....Or they might not be able to tell you anything, and simply say the game sucked, without really understanding why it sucked.""

Top 20 Apps for an Infinitely Fast Computer

Twinbee Twinbee writes  |  about 5 years ago

Twinbee writes "What would you do if you had access to an infinitely fast computer with infinite memory and zero latency? The question has rarely been asked before, but the implications could prove interesting. Some of the applications include more obvious things such as weather prediction, and games featuring incredible path-traced graphics with worlds made from molecules. But more subtle ideas explore what a programming language may look like, how graphics creation may fundamentally change, and the chance to use sheer brute force to find a Grand Unified Theory for the universe."

Renoise 2.1 Goes Gold

Twinbee Twinbee writes  |  more than 5 years ago

Twinbee writes "The music DAW — Renoise 2.0 (and more recently 2.1) has been released for Mac, Linux and Windows. For those not familar with the 'tracker' style of music editing, many would say it's a welcome change from programs such as Logic, Cubase or Reason due to the sheer speed of editing and navigating notes, which are fed into a compact and information-rich spreadsheet-like structure. Although the learning curve may be a little steeper at first than the aforementioned (keyboard shortcuts are king), trackers have come a long since the early days of Protracker, OctaMED, FastTracker et al.

Essentially, it's suitable for create anything from classical to electronic, to jazz. Standard features include full VST/LADSPA/AU support, PDC, multi-core load balancing, rock-solid GUI, envelope automation, MIDI i/o, and a decent community/forum. The latest 2.1 version offers ReWire / Jack Transport support, and pattern 'scheduling' to allow for live performance mixes."

Existence of Real 3D Mandelbrot?

Twinbee Twinbee writes  |  more than 6 years ago

Twinbee writes "Could there ever exist a true 3D analogue of the Mandelbrot which isn't just an extruded mountain, lathed rotation or Quaternion cross section? If such an object did exist, it could look indescribably beautiful. This site goes in search of the mythical beast, and gives us hope that we may even find it one day. There's also a nice 'cream of the crop' collection of 3D fractal pics on display at the end (from many artists) which are well worth a look."

MP3 Player Comparison - Winamp vs iTunes vs WMP

Twinbee Twinbee writes  |  more than 6 years ago

Twinbee writes "Skytopia recently featured a comparison of four of the most popular music organizers for Windows, including Winamp v5.51, iTunes v7.6, Windows Media Player v11.05, and MediaMonkey v3.01. The review focuses on "basic operation, including file types, searching features, tagging, and the speed of the program", and goes into quite some depth over the five pages.

Winamp turned out to be the winner, but only just. According to the writer, all of the players may be close enough to warrant sticking with for now, especially if you're used to their way of working."

Greatest Widget Toolkit for C/C++

Twinbee Twinbee writes  |  more than 6 years ago

Twinbee writes "I'm a C/C++ programmer looking to expand into the world of the GUI. The ideal widget toolkit should be cross-platform, but adhere to the native widgets where possible. It should also be simple to use with the shortest code possible, yet flexible and mature to suit large-scale projects. Finally, the applications should all run like greased lightning and have decent WYSIWYG GUI editors if possible.

After a cursory look, it would seem there are so many; wxWidgets, Ultimate++, JUCE, GTK, QT, V, Fox, Lgi, WTL, ZooLib, and SmartWin. After experiencing some of the horrors with the Win32 API, which of these are worth trying out?"

Aerogel Hailed As New Wonder Material

Twinbee Twinbee writes  |  more than 6 years ago

Twinbee writes "The amazing properties of the space-age material aerogel have been known for some time, but only now is it beginning to be manufactured for widespread use. Highlights of the news article include resistance from a blowtorch at more than 1,300C, and how "6mm of aerogel was left almost unscathed by a direct dynamite blast". Perhaps the most obvious use for the 'super-sponge' like material is for insulation, whether we're talking about mountain boots, house insulation, or any winter wear.

Quote: "However, it has failed to convince the fashion world. Hugo Boss created a line of winter jackets out of the material but had to withdraw them after complaints that they were too hot.""

Record Cost/watt for Solar Panels

Twinbee Twinbee writes  |  more than 6 years ago

Twinbee writes "We've just had a Slashdot story which reports the efficiency of solar panels has increased yet again, this time from 40.7 to 42.8%. However, what's surely more important is the price per watt statistic. It's the benchmark which more than anything else, will help propel us into a cleaner energy age.

So, Slashdot readers, what is the current record? From a quick Google, I find a few results to get us started: $26.60 per watt (Maplins). $4.40 per watt (the-green-company) $4.16 per watt (GE Energy GEPV-173 Solar Panels)

I have zero affiliation with the above companies, and no, I have no idea why Maplins panels are so expensive.

Can anyone find anything better $4.16 per watt?"

Twinbee writes "I was wondering what you lot would consider the best 2+ player games of all time. Apart from games for mixed skill players, this has never been asked on Slashdot before, so it would be interesting to see. From my own experience and research, it looks as though a top 50 would include games such as Streetfighter 2, World of Warcraft, Speedball 2, Super Mario Kart, SWIV, Ikaruga, Stunt Car Racer, Super Monkey Ball, Puzzle Fighter, and Mario Party. Whether they are competitive or cooperative, Slippery slope or Perpetual comeback, 2-player or multiplayer, retro or cutting edge, I want to hear them! I would prefer MMOG games not to be included, unless there is a good deal of interaction between the people in the 'same house' (e.g. perhaps they can team up and play against the world)."

As always with these kind of things, it's not going to be 100% accurate, but it's an interesting and humorous look at some of the weirder technologies out there."
