Sulfur Polymers Could Enable Long-Lasting, High-Capacity Batteries

bheading Lithium Ion lifetime - really ? (131 comments)

Article says "In comparison, a lithium-ion battery typically starts out with a storage capacity of 200 mAh/g but maintains it for the life of the battery, Pyun says."

Hmm. I have lithium ion batteries that can't hold a charge at all.

And it's only partially to do with how they're used. Lithium ion batteries lose capacity while in storage. Which is why you should never buy a used, or a new-old-stock one.

FSF's Richard Stallman Calls LLVM a 'Terrible Setback'

bheading Re:...but if you want free software to improve... (1098 comments)

That's part of why LLVM is better than gcc today.

Certainly, the project has obtained its objective of being a simpler, faster compiler free of the FSF's politics.

But it isn't "better than GCC". It is targeted pretty much exclusively at x86 and looking at the project's website many features are missing from other architectures (such as the assembly parser I note). I also see no sign of advanced GCC features such as stack smashing protection, mudflap and so on.

FSF's Richard Stallman Calls LLVM a 'Terrible Setback'

bheading Re:...but if you want free software to improve... (1098 comments)

The GPL approach is "Here is something nice I made - you can use it, but if you you have to let me play with you stuff.

This is a grossly inaccurate mischaracterisation.

The GPL approach is just like the BSD "Here is something nice I made - have it and do what you like, hope you have fun!". You can do whatever you want with the code. You can modify it, add features to it etc. You don't have to share the source unless you redistribute it. You repay the community who created the original work with your own enhancements to it.

Linux x32 ABI Not Catching Wind

bheading x32 is a premature optimization (262 comments)

The idea makes sense in theory. Build binaries that are going to be smaller (32-bit binaries have smaller pointers compared with 64-bit) and faster (because the code is smaller, in theory cache should be used more efficiently and accesses to external memory should be reduced).

But I suspect the problem is that the benefits simply outweigh the inconvenience of having to run with an entirely separate ABI. I doubt the average significant C program spends a lot of time doing direct addressing, and as such I suspect the size benefits of using 32-bit pointers is overstated.

Geeks For Monarchy: The Rise of the Neoreactionaries

bheading Re:hrm (730 comments)

so that the upper chamber stops being a reasonably impartial bunch of old guys who do what's right because its right

Read a few history books for cryin' out loud. There was (and to some extent, still is) nothing reasonable about the House of Lords. Back in the day many of the peers were hereditary ie only there because of their bloodline. At crucial points they interfered to try to block the democratically elected government - over welfare reform (back in Lloyd George's day) over Irish independence/Home Rule, and a zillion other things. Recently they even made noises about blocking gay marriage.

This is an institution with no mandate and no accountability to the electorate. It defies belief that someone could characterize their out of touch interference as some sort of positive influence.

25,000-Drive Study Gives Insight On How Long Hard Drives Actually Last

bheading Re:Only four years? (277 comments)

On the contrary.

As drives get larger (4TB is now readily available) they are not getting any faster.

Correspondingly, matters such as RAID rebuilds become a real issue. It takes about 12 hours for our NetApp 2020 unit to rebuild a 1TB drive, and that's with relatively low load; so a 2 day rebuild time is probably not far away. The probability of a further failure within that timeframe means you're taking a risk.

25,000-Drive Study Gives Insight On How Long Hard Drives Actually Last

bheading A very silly article (277 comments)

The article claims that nobody has published a study of hard drive failure rates before. Wrong, of course - Google did some time ago.

The guy ends the article by talking about SSDs as if they are some sort of unknown quantity. The failure modes of SSDs are much more consistent and better understood even at this early stage. Flash blocks become unusable after a fairly fixed number of rewrites. The drives measure the total number of historic writes to the drive and failure can be predicted ahead of time.

Critics Reassess Starship Troopers As a Misunderstood Masterpiece

bheading This is news ? (726 comments)

I knew Starship Troopers was a satire after I saw it, shortly after it first came out. I thought everyone knew. Some people are obviously slow on the uptake.

US Government Shutdown Ends

bheading Re:Thank goodness (999 comments)

First, it is opposed by more people than favor it

That's a curious notion.

The GOP (and the Dems) turned the 2012 Presidential election into a referendum on Obamacare - and they lost.

If most people oppose the legislation why did they vote for the guy who made it his singular legislative achievement; and why did the guy who vowed to repeal it lose ?

EU Committee Votes To Make All Smartphone Vendors Utilize a Standard Charger

bheading Can we have standard laptop chargers next please ? (415 comments)

A fine idea.

What about laptop chargers too ? Every laptop I've owned has had a different charger plug. In some cases machines made by the same manufacturer have different plugs. Have a set of standard charger ratings and a standard way for the laptop to detect it.

Why Steve Albini Still Prefers Analog Tape

bheading Obsolescence (440 comments)

"I feel it would be irresponsible to give my clients digital files as their permanent masters, knowing they would eventually disappear or become unusable, so I won't do it."

The hilarious thing about this is that I don't think anyone even makes analogue tape machines, right now. I checked Fostex, Studer, and Tascam. No tape machines being made.

Given this .. how easy will it be to play an analogue reel to reel tape in a few short years ?

Hell, I currently have no easy means to play my 4-track double speed/dbx cassette multitracks from years ago, and I have to go out of my way if I want to play an LP.

But, I can still access a tar file produced by a machine from 20 years ago, and I'd expect to have no trouble accessing a tar file from 20 years ago. Digital makes it easy to move your data as new technology comes out. Each time you copy your analogue tape you lose some of the original recording.

More Bad News From Fukushima

BT Prepares To Pull Plug On Dial-Up

bheading Re:Not bad at all (120 comments)

There is a long tradition of backwards compatibility in the telephone network in the UK.

A phone made 100 years ago will still work. Unbalanced ringing and pulse dialling are all supported.

Members of Parliament Demand Explanation For Detention of David Miranda

bheading Re:I can't answer that until I speak to my lawyer (321 comments)

Terrorism Act (2000) Schedule 7 Paragraph 18 states that if you fail to "comply with a duty imposed under this schedule" you are committing an offence.

Refusing to answer questions until legal counsel arrive may well be taken to be a refusal to comply. But I guess the courts would have to decide that.

New Doctor Who Actor To Be Revealed This Sunday

bheading Re:Needs New Writer Instead (249 comments)

Not sure I agree here, some of Davies' scripts seemed ridiculous. The Idiot's Lantern was cringe-making. The finale story arcs where the entire universe is about to be destroyed until the plot introduces a big red reset button at the end were boring. The Dalek stories were simply shit. Cybermen/Dalek face-off ? Corny. I think Davies' best (and most touching) story was Love & Monsters.

Moffatt approaches the stories in a different way, for sure, and some of his writing is sublime. He seems to have a better sense of The Doctor being a rather mysterious, enigmatic figure.

glibc Steering Committee Dissolves; Switches To Co-Operative Development Model

bheading bheading writes  |  about 2 years ago

bheading (467684) writes "Following years under controversial leadership which, among other things, led to a fork (which was in turn adopted by some of the major distributions) the glibc development process has been reinvented to follow a slightly more informal, community-based model. Here's hoping glibc benefits from a welcome dose of pragmatism."

Lynch law prevalent on Wikipedia

bheading bheading writes  |  more than 6 years ago

bheading (467684) writes "Recently a pal of mine logged into Wikipedia (where he has contributed many articles on Turkey, politics, amateur radio, and other matters over the past few years) to find that he'd been blocked as a sockpuppet — this despite the fact that he posts under his real name. So, he logged in at work to submit a request to be unblocked — and found that his work address was already blocked. He then submitted the request protesting his innocence as soon as he got home — but awoke the following morning to find that his home IP had also now been blocked as having been used by a sockpuppet. Then, Gerry blogged the matter to bring his problem to the attention of other friendly Netizens, others who weighted in to protest his innocence found themselves blocked as well. Further investigation has shown that the formal Wikipedia blocking process was not followed, leading to suspicions of political bias. Wikipedia's getting to be a rough place if you can be silenced for your political views, then silenced automatically for merely attempting to protest that decision — and then your friends get silenced for coming to your aid. Have any other Slashdotters encountered problems like this lately ?"
