Ask Slashdot: Sounds We Don't Hear Any More?

leathered Re:The whine of the flyback transformer (790 comments)

I disagree. The problem is that there is there is no LCD monitor that does everything competently. $1500+ professional color-accurate monitors may be good for photoshop but are lousy for anything with moving images.

Want a good LCD for gaming? There are TN panels that will refresh at 144Hz with fast response times. The tradeoff is very poor color reproduction and narrow viewing angles.

An IPS panel will give better colors and viewing angles at the expense of low refresh (few go over 60Hz), and 'IPS glow' is a real problem with them.

Then there is the panel lottery you have to play when you buy them. Many vendors and manufacturers have a threshold for the number of dead/stuck pixels that are deemed acceptable. Backlight bleed and uniformity can vary widely between different monitors of the same make and model.

CRTs had issues with their bulk, limited size and power consumption but LCD have introduced a whole world of new problems.

Perhaps our only hope is more affordable and reliable OLED displays.

Ask Slashdot: Sounds We Don't Hear Any More?

leathered Re:The whine of the flyback transformer (790 comments)

I'm using a CRT monitor right now, a 21" IBM P275 with a Trinitron tube. Right now I'm enjoying near perfect color reproduction, blacks that are actually black, zero input lag, no ghosting, nothing that resembles backlight bleed and no stuck/dead pixels. Haven't noticed flyback whine for years but that's probably down to my age. LCD is still inferior to CRT in many ways and you have to wonder what CRTs we would have today if development had continued. LCD has also taken a step backwards recently with the introduction of LED backlights, they make for thinner panels and lower power consumption but uniformity of many recent panels is really poor.

Having said that, my CRT will probably have to go this year, most probably late in the spring when the heat the thing generates is no longer welcome. My desk is also sagging from the weight of it sitting there for nine years.

Ofcom Will Remove Mandatory Ham Callsign ID Interval, Allow Encryption For Some

leathered Ofcom (57 comments)

If Ofcom really want to help ham radio operators they could do more to ban or restrict power network adapters and the multitude of other gadgets that leak QRM all over the airwaves.

Bring back the Radiocommunications Agency. Ofcom is a behemoth that has its fingers in too many pies to be an effective regulator.

World War II Tech eLoran Deployed As GPS Backup In the UK

leathered Re:Err - no. (139 comments)

In the UK pilots often receive NOTAMs stating that the military are conducting GPS jamming trials in certain areas. From personal experience and reports from other pilots the jamming is very effective.

Mozilla 1024-Bit Cert Deprecation Leaves 107,000 Sites Untrusted

leathered Re:So 1024 Bits Not Enough Now? (67 comments)

I was thinking the same, and I'm no expert in cryptography. After all distributed.net have spent 12 years trying to brute-force a 72-bit key and have only managed to test 3% of the total keys. 2^1024 is such a mind-bogglingly large number the entire world's computers couldn't crack it in a billion lifetimes.

Anyway, wiki to the rescue:

As of 2003 RSA Security claims that 1024-bit RSA keys are equivalent in strength to 80-bit symmetric keys, 2048-bit RSA keys to 112-bit symmetric keys and 3072-bit RSA keys to 128-bit symmetric keys. RSA claims that 1024-bit keys are likely to become crackable some time between 2006 and 2010 and that 2048-bit keys are sufficient until 2030. An RSA key length of 3072 bits should be used if security is required beyond 2030.[6] NIST key management guidelines further suggest that 15360-bit RSA keys are equivalent in strength to 256-bit symmetric keys.

'Godfather of Ecstasy,' Chemist Sasha Shulgin Dies Aged 88

leathered Re:Saw the old man 10 years ago (164 comments)

It was amazing to see a nearly 80 year old man bouncing around. He is the same age as my Grandmother, yet he had more energy and was more with it than she was at 60.

I'd love to know his secret.

The Ever So Unlikely Tale of How ARM Came To Rule the World

leathered Re:The future could be all in the fabs (111 comments)

I think that's a poor example as Intel no longer make 8031s and 8051s and they can't earn money by selling licenses for them because the patents expired long ago.

The Ever So Unlikely Tale of How ARM Came To Rule the World

leathered Re:The future could be all in the fabs (111 comments)

Not really, what matters most is cost, and at that ARM wins hands down. Most ARM chips cost less than $5, with some selling for pennies. Intel enjoys 60%+ margins on everything it sells and they will experience a lot of pain giving them up.

The only way Intel can compete is if they sell their mobile chips at or below cost. Oh wait, they already are.

Star Trek Economics

leathered Re:I believe that this is best described (888 comments)

Indeed. I've always found the Star Trek universe to be a poor imagination of a post-scarcity society. The Culture books do it so much better, especially with their interactions with less advanced civilisations. Starfleet would have been a much more interesting organisation if they had their own 'Special Circumstances' department.

Open Source AMD Driver Now Supports OpenGL 3.3 — and It's Getting Faster

The real embarrassment is that Windows is already up to 8.1, while the Linux kernel is only at 3.1

Get your shit together Linux!

Australian Team Working On Engines Without Piston Rings

leathered Re:How about Ceramic Engines ? (368 comments)

The chief reason why ceramic engine doesn't make it into the mainstream despite having had under research since the 1970's is that the friction in between the piston ring and the wall of the bore itself result in the wearoff of the ceramic material in the form of a pile up of fine ceramic dust inside the chamber.

Interesting. I appreciate the reason for not having ceramic cylinders bores, but why haven't ceramic cylinder heads and pistons been implemented? Surely a 'semi-ceramic' engine is feasible?

British NHS May Soon No Longer Offer Free Care

leathered Re:Rose-tinted view indeed (634 comments)

FWIW I work for the NHS. The Labour governement indeed poured billions into the health service during their term but it was almost totally squandered on failed IT projects, an army of midde-managers, non-jobs and grossly overpaid execs.Very little of it was invested in actual patient care.

I do believe the Tories are genuinely trying to fix it, my problem with them is that they're doing their usual carpet-bombing approach instead of carefully targetting the gross inefficiencies that are blighting the NHS.

Google Wants Patent On Splitting Restaurant Bills

leathered Re:Tapwater in Germany (196 comments)

I used to work in a UK lab that tested drinking water and I can confirm that the quality of tap water usually far exceeds that of bottled water. Bottled water is unlikely to make you ill, but if you are drinking it for some perceived health benefit then you're wasting your time and money.

Bottled water is one of the biggest rip-offs of modern times and is unecessary given that all European countries have to comply with strict EU water quality regulations. Not to mention its cost and the damage it does to the environment.

UK consumers reporting contactless payment errors

leathered leathered writes  |  about a year and a half ago

leathered (780018) writes "The BBC reports that some customers of UK retailer Marks and Spencer have reported that the store's contactless payment terminals have debited their cards despite being in their bags or pockets, sometimes paying twice when they have used another payment method. The cards are supposed to work only when the card comes within 4cm of the terminal. Customers of fast-food chain Pret a Manger have been reporting similar problems, and in both cases cited the customers weren't even aware they had been issued with NFC-enabled cards by their bank."
