The Improbable Story of the 184 MPH Jet Train

Andy_R Re:And? (194 comments)

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.

Evidence of a Correction To the Speed of Light

Andy_R Re:Ummm (347 comments)

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.

A Call For Rollbacks To Previous Versions of Software

Andy_R This would fix bait and switch adware games (199 comments)

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.

Cameron's IP Advisor: Throw Persistent Copyright Infringers In Jail

Andy_R The only other solution... (263 comments)

...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?

Andy_R Re:Who, not what (796 comments)

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

The Difference Between Film and Digital Photography (Video)

Andy_R Re:200$ is fine (182 comments)

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

Andy_R Re:Crowdfunding could be the future (112 comments)

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

Andy_R How cheap would the old one have to be? (381 comments)

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 £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?

Andy_R Re:Depends on your hardware of course! (488 comments)

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.

Developers will still get their hands on Leopard at the WWDC but it will only be a "near final" version, not the finished product."

Andy_R (114137) writes "For over 25 years, Apple (the computer company) and Apple (the Beatles record label) have been arguing over the right to use of the name. Today, the dispute is officially over, with the computer company taking control of the name, and licencing it back to the record company for them to use. The BBC report has some quotes from both sides, which seem to hint that the music of the Beatles which has never before been licenced for download sales may soon be available through iTunes."

Andy_R (114137) writes "Sony have finally committed themselves to a European launch date for the PS3, after disappointing European fans by not having the promised worldwide simultanious launch, then missing the lucrative Christmas period. The BBC are reporting that the console will arrive on the 23rd of March. We'll only be getting the 60Gb version at first, and it will be priced at 599 Euros or 425 pounds in Britain. At today's exchange rates, that's a wallet-busting $835.99!"

Moderation options I would like to have

Andy_R Andy_R writes  |  more than 9 years ago

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.
