The Improbable Story of the 184 MPH Jet Train
The frontal area to mass ratio of a train is tiny compared to almost every other form of transport, so that's less of a problem.
The limiting factor with trains is usually the track, for really high speeds you need to almost completely smooth out the bends and flatten the hills, the impressive part of the jet train is that it went so fast on a track designed for much, much lower speeds.
Toyota's Fuel Cell Car To Launch In Japan Next March
I have one here, on this blank sheet of paper.
Evidence of a Correction To the Speed of Light
That all makes sense, but it doesn't seem to match up to the observations.
The article says neutrons were observed arriving hours before optical photons, but what you are saying is that photons of high enough energy to become temporary particle pairs should arrive later than lower energy ones, which don't get slowed down by temporarily dropping below c.
If the chance to become a particle pair varies with energy, we ought to see the supernova change colour, starting off shining brightly in the visible spectrum only, then gradually becoming bright at higher and higher energies, as higher energy photons emitted at the same time as lower energy ones arrive progressively later on.

Time to dust off that Acorn Archimedes!
Can You Tell the Difference? 4K Galaxy Note 3 vs. Canon 5D Mark III Video
To paraphrase Pauli, that's so bad it's not even wrong.
BMW Created the Most Efficient Electric Car In the US
Miles per gallon of electricity of course, tell you how far you'll get on a one gallon leyden jar. America is *really* committed to not going metric.
A Call For Rollbacks To Previous Versions of Software
It seems to be an increasingly common tactic for games developers to put out an advert-free game, wait for it to gain market share, then force an 'upgrade' that has no improvements at all, but is crammed with so many adverts that the game is barely playable. I deleted "4 words 1 picture" when it turned into "4 words, 1 picture, 1 full screen advert", but I would rather have kept the old, playable version on my phone.
California Students, Parents Sue Over Teacher Firing, Tenure Rules
As I read it, the word 'poor' in the summary was used in the 'not very good' sense of the word, not as in the financial sense.
Cameron's IP Advisor: Throw Persistent Copyright Infringers In Jail
...is legalisation. Non commercial sharing of information isn't wrong, or bad for the economy, so the best solution is to legalise it.

Ask Slashdot: What Are the Books Everyone Should Read?
Anathem rewards persistence, it's not an easy book to get into, but if you stick with it, you'll be taken on a seriously impressive journey. There's a strong chance you'll come out the other side thinking it's one of the best books ever written, and that Fraa Jad is... well, I can't say much without spoilers, but he's one of my favourite literary characters ever.

Mathematicians Team Up To Close the Prime Gap
Well, the summary may be misleading, but it seem to say that a proof has been found that the gap between two consecutive primes is NEVER over 600.
Cadillac Unveils Pricier Alternative To Tesla Model S
Spot on, simply swapping the launch dates would have made the Volt look like a cheap Cadillac, instead of the Cadillac looking like an overpriced Volt.
Microsoft Makes Another "Nearly Sold Out" Claim For the Surface Line
Try adding the words "Potential Microsoft Surface" to the front of that sentence and it works a bit better...
The Difference Between Film and Digital Photography (Video)
Now is a not a good time to buy if you want to cover both stills and moving image with one machine, the inevitable convergence of the two devices hasn't quite happened yet, and we're on the brink of consumer 4K video being possible.
Give it a year or two and there will be truly convergent devices in all price ranges, and a glut of second hand non-convergent and/or non 4K devices on the market because rich people have rushed out and bought the shiny new stuff.
Gaming Legends Discuss Using Kickstarter For Their Next Projects
Kickstarter for video games is problematic, because it's not a nice easy 'do to this will cost that' system. For board games, it's great - the game is ready to be put into production and kickstarter lets the publisher fund the bit that needs to be paid out to a third party to make 1000 nice duplicates of their rough cardboard prototype. If demand is high, the quality and number of components can go up, if it's too low to make production worthwhile, then investors lose nothing.
For video games it's not so clear what overfunding achieves, since doing more adds complexity that will likely slow down delivery. High (say 500% +) levels of overfunding will either disappoint if the game cost it's original funding level to make and the developer pocketed the rest, or make the final product drastically different to the original plan.
This (coupled with the fact that I got roped into do some of the advertising for it) is probably why I've backed a boardgame and a wallet on kickstarter, and an album on Pledgemusic, but never a video game.
Microsoft Takes Another Stab At Tablets, Unveils Surface 2, Surface 2 Pro
No sign of a price cut on the old one here in the UK yet (and there's no hope in hell I would buy version 2 at list), but this got me thinking... how cheap would the old models have to be before I would pick one up?
The Pro, I'd probably take a look at if it was in iPad price range, but the RT... if it was in the Â£100 area? I'm still not sure. One thing's for sure, the keyboards are laughably overpriced. Here in the UK, at today's exchange rates, you'll have to fork out a cool $176.51 for the real keys one, and $104.30 for the squishy one.
Ask Slashdot: Is iOS 7 Slow?
Actually, it seems to depend on your software a lot more than hardware. iPhone 4 users (like me) seem to get a speed-up if they regularly manually close background apps and tweak the settings to block uncessary GPS use, and a slow down if they don't.
My phone *seems* snappier at some things, but probably isn't. For example the unlock screen is noticeably more responsive, but that's probably because of the much bigger swipeable area, and the 'swipe a notification to launch the relevant app feature. The only noticeable slow down is the zoom animation when launching of leaving an app, but that's more thanoffset by the things that take a lot less taps than before, like turning off wifi.
The best feature for me is one that hardly gets mentioned in reviews; the ability to block contacts. No more 7:30 am text messages from the dumbass phone company telling me my bill is ready to view, and that idiot who can rarely dial his daughter's number correctly will finally be silenced. Considering the phone company wanted me to pay them half my line rental again to do this, getting it for free is a great deal.
Multi-Display Gaming Artifacts Shown With AMD, 4K Affected Too
I think you mean you wouldn't have these problems on a Mac (*ducks*)
Moderation options I would like to have
Starting from the premise that what mods are doing is editing the replies with the objective of making the reader experience better rather then simply 'grading' posts...
+1&-1, unintentionally redundant
Quite often, 2 excellent posts say the same things, and appear moments apart. Clearly the posters put a lot of thought into writing them, and might also have been insightful, etc, and it's sheer bad luck that someone wrote the same sort of thing at the same time. The post is of no use to readers, so 'redundant' should be used, but it's not the poster's fault, so when I'm modding, I hesitate to use a karma-hitting mod point. What I would like is a modding option that gives the poster karma for their good intentions, but demotes the actual post out of the way of readers.
-1, sense of humour failure
All too often I see posts made at +2 that pick logistical flaws in posts that are clearly intended to be funny. They don't add anything to the discussion, and are not really useful to anyone reading the story, but there isn't really a good way to mod them down. I occasionally use "overrated", but it doesn't really fit well or get the message through to the poster.
Would anyone read my journal, if I wrote in it?
3 positive replies and I'll write stuff.
