That would, you know, require them to find something that actually benefits you. I do not think the advertising industry still has that skill. It seems to me they now rely fully on trying you to convince to buy products you do not need and (originally) did not want.

Honeywell Home Controllers Open To Any Hacker Who Can Find Them Online 13 13

Trailrunner7 writes: Security issues continue to crop up within the so-called "smart home." A pair of vulnerabilities have been reported for the Tuxedo Touch controller made by Honeywell, a device that's designed to allow users to control home systems such as security, climate control, lighting, and others. The controller, of course, is accessible from the Internet. Researcher Maxim Rupp discovered that the vulnerabilities could allow an attacker to take arbitrary actions, including unlocking doors or modifying the climate controls in the house.

Ask Slashdot: Everyone Building Software -- Is This the Future We Need? 103 103

An anonymous reader writes: I recently stumbled upon Apple's headline for version 2 of its Swift programming language: "Now everyone can build amazing apps." My question: is this what we really need? Tech giants (not just Apple, but Microsoft, Facebook, and more) are encouraging kids and adults to become developers, adding to an already-troubled IT landscape. While many software engineering positions are focused only on a business's internal concerns, many others can dramatically affect other people's lives. People write software for the cars we drive; our finances are in the hands of software, and even the medical industry is replete with new software these days. Poor code here can legitimately mess up somebody's life. Compare this to other high-influence professions: can you become surgeon just because you bought a state-of-art turbo laser knife? Of course not. Back to Swift: the app ecosystem is already chaotic, without solid quality control and responsibility from most developers. If you want simple to-do app, you'll get never-ending list of software artifacts that will drain your battery, eat memory, freeze the OS and disappoint you in every possible way. So, should we really be focusing on quantity, rather than quality?

Comment Re:Unfortunately, it is not (Score 1) 101 101

Quantum computing requires perfect scalability. Effects that are unmeasurable at 1 or 10 qbits can easily kill calculations with 100 qbits completely. As there are no entangled systems with 100 qbits, it is unclear whether such inaccuracies are there or not. Practical applications, incidentally, require likely 1000 entangled qbits and more.

So, no, "unmeasurable" at current entanglement numbers are meaningless to predict feasibility at higher numbers. And much higher numbers are needed before quantum computing offers any advantages. It is not even clear whether entanglement itself scales or runs into fundamental limitations at some point. The theory says it does not, but it is theory, not verified reality.

Comment Unfortunately, it is not (Score 2) 101 101

Quantum computing is about where teleportation, strong AI, a perfect cure for cancer, etc. is, namely it is completely unclear whether it will ever work. All this bullshit about Quantum Computing is just that: Bullshit. We do not even know whether the physics allows it, all we know is that the current theory (which we know is incomplete and inaccurate) would allow it if it was accurate.

Currently Quantum Computers Might Be Where Rockets Were At the Time of Goddard 101 101

schwit1 writes: If quantum computing is at the Goddard level that would be a good thing for quantum computing. This means that the major fundamental breakthrough that would put them over the top was in hand and merely a lot of investment, engineering and scaling was needed. The goal of being able to solve NP-hard or NP-Complete problems with quantum computers is similar to being able to travel to the moon, mars or deeper into space with rockets. Conventional flight could not achieve those goals because of the lack of atmosphere in space. Current computing seems like they are very limited in being able to tackle NP-hard and NP Complete problems. Although clever work in advanced mathematics and approximations can give answers that are close on a case by case basis.

Sigh... Coal is only useful for base load. The spool up time for coal is too slow for peaking.
Natural gas is ideal for peaking since you can use it in gas turbine plants for peaking since the spool up time is so fast.
I showed you references do you have any data at all to back up what you are saying?
France may or may not use natural gas for base load but many nations do since it is so cheap and clean.
I would say that the engineers in France are knowledgeable and I would also bet that they would agree with what I am saying. Too bad it is the political parties that want to cut nuclear.

"It would not ... as most CO2 is produced by cars, house heating and industry."
Since renewables only generate electricity we can ignore all none electrical sources as far as nuclear and renewables. Unless you want to count the tiny number of passive solar heating installations.
If you look at this graphic http://energytransition.de/fil...
You will see that France gets around 10% from hydro. You will also see that France still gets some power from coal which is baseload power is is ideal to replace with nuclear. The natural gas is probably split between base load and peaking load. Replacing the base load with nuclear is again a simple matter the peaking is a more difficult issue which is why I suggested that France should convert their hydro from a base load to a peaking source aka as pumped storage. The power stored would come from a combination of both renewables and nuclear.
As to your comment about where the majority of CO2 comes from do you have any sources?
My research shows that home heating in france is more often than not electrical heating. https://www.justlanded.com/eng...

Do you have any real data or just insults?
