No, the debugger can run the app as a child process, retaining the ability to peek into its innards.

Zionists stole my SHOE, claims Muslim campaigner

Re: A few pointers

Before making accusations of ignorance, may I suggest that you first research the Koran, the Hadiths, and the culture. There are exhortations of the 'kill everyone who doesn't agree with them' type in there, thankfully most submitters to the religion don't do that these days. Along with the positives, there is also a rich history of jihad, subjugation of women and minorities, and other things that Western culture consider to be negative.

Re: A few pointers

" It's a dumb narrative as there's 1.6 billion muslims in the world from every walk of life and one thing that I certainly do agree with this guy on is the danger and idiocy of Islamophobia."

That's an implied threat against anyone who questions that religion. It is a regression to pre-Enlightenment attitudes of religious repression of thought and speech.

Re: Being picky...

In most manual gearbox cars the only thing preventing you inadvertently selecting reverse gear is some kind of extra selection device, e.g. a pull-up collar on the gear stick, or a push down mechanism on the stick. If you really really want to select reverse whilst travelling forward at speed, you can.

Re: Have you tested this theory?

Capacitors have more of a problem with low pressures, especially types that do not have a hard case, e.g. resin dipped tantalum. The airworthiness directives are a good guide.

Easy ... easy ... Aw CRAP! SpaceX rocket ALMOST lands on ocean hoverbase

Re: Needs One of These

Many of the good ideas have already been invented. They could make the entire deck of the barge out of that grab grill, the landing wouldn't need to be so precise, and the rocket exhaust would go straight through, reducing the landing flare (http://en.wikipedia.org/wiki/Landing_flare) instability.

Marvell: We don't want to pay this $1.5bn patent bill because, cripes, it's way too much

Gideon 1

The main issue here is that Carnegie-Mellon took so long to file suit. If Marvell had been challenged earlier they could have raised their selling price for the chip by the 50c patent license fee. Carnegie-Mellon should be penalised for taking so long to take action against Marvell.

This is the European Commission asking some questions to see if some illegal contracts have been signed between Apple and the music industry.

Soundbites: News in brief from the Wi-Fi audiophile files

Gideon 1

"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.

Boffins brew TCP tuned to perform on lossy links like Wi-Fi networks

Gideon 1
Go

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.

Google search biz offer BINNED by EU competition chief

Gideon 1

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.

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.

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.

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.

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.

AMI PC firmware upgrade scare: The global security meltdown that wasn't

Gideon 1

Overstated

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.
