"96Khz or 192khz? - 44.1 Khz is a higher 'resolution' already than my (and your) ears can hear. At 96khz and with the right equipment you are either tormening your dog or delighting him with bits of your music that you will never hear."
Higher sample rates improve the phase accuracy of high frequencies, not an issue for mono but in stereo it helps you pick up the direction a sound is coming from.
Higher sample rates also make the anti-aliasing filters much easier to design, and reduces their effects on the audio you can hear.
My kid has already got bored of Minecraft and moved on to other games, like Roblox which allows greater user game creation possibilities. If this the sale goes ahead Notch may have got his timing just right.
Re: Weigh the bloody thing
Much simpler: A strain gauge (resistor printed on a piece of sticky film, responds to stretch or compression) on the landing gear strut will measure its load.
We're on BT business broadband and got taken offline by the fault, so either it was BTs fault or BT route their broadband over Gammas network.
Re: Fixing at the wrong layer
Retries are bad, especially if the round trip time is long. Better is to increase the forward error correction to compensate for the radio link quality as it adds a much smaller overhead to both the local radio channel and the long distance fibre links, keeping the retry rates down. WiFi needs more of the redundancy coding goodness developed for LTE.
These studies often only consider their own data throughput, selfishly grabbing bandwidth at the expense of other users sharing the same links. TCP/IP was carefully designed to allow efficient sharing of limited bandwidth, and that is where many of these proposals fail.
Fixing at the wrong layer
It's the radio transport layer that needs the forward error correction applied when the signal gets ropey, sort it locally where there is information about signal strengths and error rates rather than have the TCP stack compensate for a problematic link that could be thousands of miles away.
Re: @Suricou Raven (was: @ Brian Scott (was: Broadcast?)_
UDP broadcast is used routinely even if you don't like it, e.g. by printers and printer drivers for auto discovery and toner low messages.
Micro-bolometer LWIR sensors don't need cooling, they operate at room temperature.
Also, if your contact lens were the size of goggles...
Re: Hand is up
ARM can do both endians, but it is usually run in little endian mode just like x86.

Re: vertical search?
"this was about Google's control of the search market meaning they can decide whether any web-based business goes bankrupt or not, and that they may pull these levers with impunity."
We've had experience of Google doing this. We appeared at positions in search results appropriate to our website and company size until Google noticed us and rang up saying they could 'optimize' our spend with them. When we said we were ok, thank you, we then mysteriously dropped right down the search results, and our adwords per-click minimum bid prices became very expensive even though nobody else seemed to be bidding for them.
Jpeg2000 never caught on either
It did, except it is called REDraw.
Re: It's all about who you employ
Mossad agents have sometimes pretended to be from other nations security services.
It's all about who you employ
These leaks are failures of vetting, and failures of need-to-know policies. Both become difficult to maintain when the numbers of employees in the organisations reach the numbers in GCHQ and NSA.
Nothing new - move along now
Running without an OS is common stuff in embedded systems. Yawn.
Some UK houses have them to feed a standard lamp from the main room light switch, or as a dedicated supply for an electric heater on night tariff, or even as a supply for a clock.
Twisty roads aren't as dangerous as straight ones with occasional blind corners/dips. I live on one of the most dangerous roads in Scotland, the A70 which, like the A9, couldn't be described as twisty.
The bbc news website version of this story has a lot more detail, including about how the scientists came to their conclusions. I'll leave it to you to find the link for it as our hosts here might not like me putting it up.
Re: Bang on...
Giving her something like that has the benefit of lowering her expectations, and forces her to be more explicit about what she would really appreciate instead of expecting you to mind-read her.
So disappointed, after three boring minutes I was expecting its head to explode or something...
Re: ...torches can be like pencils or tape-measures...
I discovered stainless tape measures, they work even if it rains.
Just install the Flashlight app.
Re: Bad example.
It would take a very large amount of fire to attenuate the radio signal, e.g. earth atmosphere re-entry plasma.
Re: Nice idea but
Even very hot fires emit lots of thermal radiation in the long and medium wave IR bands. Have a look at Planck's law.
Re: Nice idea but
Yes, I'm sure, my work is developing thermal cameras. Thermal cameras show thermal radiation, from which actual temperatures can be inferred, not just differences in temperature. Walls and glass windows are opaque to thermal wavelengths, the wall will show a cold patch if the cold water is directly hitting and cooling the wall.
The heat from a person gradually spreads through the rubble through both conduction, convection and draughts. Thermal cameras can resolve very small temperature differences, in the order of 10s of milliKelvin, allowing you to see these effects.
Re: Nice idea but
Thermal cameras can only see through walls in Hollywood films, not in real life.
Post Office 746 classic telephones (new but old stock with new cables) are still available after BT found a warehouse full of them and sold them on. They come in rather fetching 1970s colours.
Are you sure you want to do this?
This could be soliciting for information, and there is no "in the public interest" defence under the Official Secrets Act.
Re: Am I the only one...
It would be even better if they ditched DCT based compression for one that seamlessly supports decode to lower resolution, e.g. wavelet, for then the tv/mobile would only need to download enough resolution to fill its screen/bandwidth limit.
Motorola and Nokia have shown how fickle the mobile biz is, one minute you're top of the heap making huge profits, next you are losing money on every phone you sell.
Smart meters monitor voltage? Why?
You don't need smart meters to reduce demand peaks. Smart appliances monitor the mains FREQUENCY as it drops when the generators are overloaded. Voltage is automatically adjusted by the substation changing transformer winding tap.
The PC bios has been disassembled and clean room rebuilt many times. Having the source code can help to find weaknesses, but a black hat still needs to look at the machine code dump to confirm one. In any case, if they were trying to make it very secure, they ought to publish it for others to analyse for weaknesses, obscurity is not security.
Re: RE: 100 amp 3-phase supply installed
Decent metalworking lathes are typically run from a single to three phase invertor these days. You do not need or even want the high power availability of pukka three phase, if the tool catches in the workpiece your lathe will be in bits. Inverter drive also has the benefits of continuously variable speed, and soft start.
Re: @ frank ly - @ M Gale
The butler tells the housekeeper to tell the servants to go shopping? No, the vendors come to the tradesmans entrance to drop off their goods. You cannot possibly know a typical Rolls Royce owner...
It would be very embarrassing for Apple if the court ordered that their execs be imprisoned for a month if they ever set foot on British soil, the media worldwide would enjoy that. It's hard to see what else the court could do.
It gives them so much to hope for with a very small outlay. Fantastic value. Also, don't assume all pensioners are poor.
Having employees strongly motivated by money in the intelligence community would be a security risk.
Jury of Your Peers
A Jury of Your Peers is an outdated form of justice, where a Lord would be tried before a jury of Lords, avoiding being automatically found guilty by a jury of serfs. A juries are now selected from lists of voters.
Re: Is that vacuum still vacuum?
Maybe the Aerotec motor won't even sustain a smolder in the vacuum?
Is the vacuum maintained during the delay between the igniter firing and the motor burn? The smolder could slowly reduce the vacuum to the point where the motor burns properly, which won't happen at altitude and could lead to an in-flight failure.
Our chip shops (Edinburgh) sell deep fried battered spicy haggis as well as the standard (premium?) stuff similarly attired. Would like to see it in spicy batter with curry sauce, mmm.
The answer is GPS jammer seeking missiles.
Works both ways
I hope the powerline networking kit is also immune to 100+ Watts of HF modulated carrier transmitted nearby, hehe.
"Write information on them too many times and you'll only be able to read them after that."
No, it will progressively get smaller as the flash blocks wear out. When the number of usable spare blocks drops to zero, you will need to delete (erase) data off the SSD before you can store anything new.
The bigger problem is that the filing indexes are also stored in flash, and when you run out of spare blocks to store them, the entire SSD can fail. The vendors tend to over provision the spare blocks to mitigate against this, but how successful has this strategy been?
Re: Why hasn't anyone considered using goats?
Goats are browsers, not grazers. They'll eat all your plants, bushes, trees, and washing on the line before jumping into the next garden to do the same, leaving the grass to grow. If you want grazers, try sheep or geese.
Yep, yet again.
I had this, the update even corrupted the installer files, preventing uninstall. Nuked .net entirely with the dotnetfx_cleanup_tool, it's amazing how much quicker the machine boots without .net.

Erm, Douglas Adams isn't likely to be telling them to drop DRM anytime soon, he's dead.
