Sharks with lasers!
1) Breed a tiny shark species.
2) Put a little 500mw laser on its head.
3) Build a (very) small pool inside the pitot tube.
4) Teach the shark to kill anything that comes inside.

I was sent to do a server deploy. Took the plane, short 1hour 30 minutes flight, got there.
There was no one to meet me. 4 hours later, found what happened: one director hired the job, and went on a trip. The other director was never informed of the job - and went to another city too!
I spent 5 paid days seeing the sights. Easier job ever! :D
Asus Zenfone 2.
Patch level: 1st jan 2016
Android version: 5.0
Kernel version: 3.10.20 <- sigh
Ah, well. Can't have everything. Asus promised android 6 very soon. One can always hope...
That's what I have been saying for some time. I believe Google should make something like Windows is: an OS installer, wich can be put in any PC.
Drivers (sorry, modules) could be loaded as any Distro does: after the boot, on a "need to use" basis. There would be need to a (very) small kernel to do the initial boot - and that's it. Just enough to use memory and read the internal storage. No one would need network, or sensors, at this stage.
So. Minimal OS. All, or almost all, Google services installable as apps - just the core functions would go inside the OS BLOB.
Everything an OEM would like to install should be an App. This way, Google upgrades the SO, OEMs upgrade their shell. And everyone is happy.

"If redhat is gpl then why can't I download or obtain it for free? or am I missing something here."
You can download (and redistribute it!) for free - after You buy it. GPL does not mean "free as in beer". RedHat has every right to sell its Distro to You.
Under the GPL they have to give you the source code too, an You are free (as in freedom) to pass forward both the source and the binaries.
Intellectual property, trademark and so on, are not part of this.
By the same token, RedHat has no obligation whatsoever to keep publishing corrections to its Distro (barring maintenance contracts). They charge You for the privilege of downloading the upgrades - and these upgrades are under the GPL too.
"Time for boffins to come up with a defence against laser pointers..."
It's not THAT hard. I mean, it will cost money. And a lot more than they are willing to pay. But...
What lasers do we have today, commercially sold?
Each one of them working with an extremely narrow range of frequencies. Put some film inside the cockpit windows that blocks these specific wavelengths. There may be some change in the scenery colors, due to these missing colors, but I don't think it would be important.
Even the red ones. The red lights use a much larger spectrum than the laser pointers.
"Is this article saying that on an AMD processor, if it states 8 cores, the gadget I use would report 8 processors? Do Intel hyper-threads=AMD cores or have I missed the point of this entirely?"
HyperThreading is quite different from what AMD has.
Roughly (very) speaking:
HyperThreading uses parts of the CPU pipeline that are unused, to process another instruction. It doesn't double the performance, but it helps.
AMD went a different road: It made two CPUs, and stripped some parts of one of them. Then both where glued together. Is more complex than this, but...
So. One AMD unit (sold as two cores) has:
One decode unit
Two integer pipelines
One FPU unit
One assemble unit
The catch: It is faster to decode than to process. In most (no all, but most) cases there is no difference from having one or two decode units to two pipelines.
The FPU is 256 bit wide. It can process one 256bits instruction per clock. But it can process two 128bits instructions per clock, or even four 64bits instructions per clock. And not all FPU work is 256bit.
If memory serves me right, the assemble unit goes the same way of the decode unit.
"It seems to me that the plaintiffs are using the term 'instruction[s]' in a very specific, restricted sense to mean a "complex math calculation" and therefore one that must engage the shared FPU. Unless I am gravely mistaken, however, there are plenty of instructions that would not need to engage the FPU."
Yes, but it is worse than that.
The Athlon FX FPU is a 256 bits part. It can process ONE 256 bit operation each time. BUT it can process TWO 128 bit operations simultaneously - or even four 64 bit operations!
So, it is a little more complicated than "on FPU equals to one processor" argument. Would he be happier if each core used a 128 bit FPU?
"I've always considered AMD to be selling a weird, kind of weak variation of hyper-threading as two physical cores."
Weird, but wrong. The AMD cores are far worse than the Intel ones - but the "dual thread" technology AMD uses is far better than Intel's HyperThreading.
Let me explain: HyperThreading can gain you a 30% boost - at best. In some weird cases it is better to have it disabled (Intel says so, in case of virtual machines). Real world scenario, it will gain You something about 15% speed.
AMD dual thread technology does not have this problem: it is recommended to keep it always on, and there is no situation where it would harm the speed.
The difference in speed is not because of the HyperThreading/duas thread technology> it is because the AMD CPU architecture (today) is inferior.
"Seems that much, if not most, of a "module" is single threaded. If you can only fetch one instruction at a time and you can only decode one instruction at a time then a module is not really a two-core unit."
Not quite. You see, the time used for fetching is far less than the time used for computing. IK am not saying that AMD chips are the best thing on earth (they aren't), but
1) Usually a single fetch unit can keep busy two integer pipelines
2) We can argue that an 8 module (to use AMD's terminology) CPU would be better than a 4 module CPU. No doubt about it. But that's not the question. The question is if AMD right in calling the 4 module CPU an 8 core processor. I believe so, but that's just my opinion.
3) It is true that it shares a single FPU with two integer pipelines. But it shares a more powerfull FPU. Check it. The Athlon FX FPU is more powerfull than the Athlon FPU. If memory serves me right, its is 256 bits versus 192 bits.
Now, real world information: I run the standard PovRay benchmark in a FX 6300. It was better than on a i5 of equivalent generation and clock. The run time was about 30% worse for the FX - it used that much more computing time. But this computing time was spread through its six cores. So, it completed the benchmark about 25% faster than the i5.
And I ask: would be justifiable to cal this 3 module a six core?
This looks to me like someone is just trying to get some easy money.

"Still cleaner and more sustainable than Solar or wind
Not sure if I've seen a major environmental disaster attributed to one of those though."
I don't know which one is cleaner, but:
1) Solar covers huge areas with mirrors. Bad for the ground, plants and (I imagine) changes the heat absorption rate of the area.
2) Solar which boils liquids - opposed to converting light into electricity directly - are known to burn birds mid-flight, as they cross the beam.
3) Wind turbines are great bat killers. They pass through the arc of the propeller, and the low pressure behind the blades explodes their lungs.
4) Wind turbines are know to make a very low frequency "hum". I don't know how bad it is to the animals - but can't be good. There are people that complain about the hum: it interferes with the sleep, if I'm recalling it right.

"How about: "A person and some people."
That should fix all potential issues, yes?"
No, no! This will not do it! You see, "some people" is clearly derogatory, implying that the "vertically challenged people" are less than the tall (and white!) one.
This is clearly a disaster, and we should scrub the whole thing. How about a choir, with just the vocalization? You see, lyrics are far too prone to offend someone to be permitted.
"Actually the A10 is more likely to survive over a battlefield than any other type."
Too true. That thing is a flying nightmare. It takes an unbelievable amount of punishment - and insists on keep going!
"Yes, there's a lot to be said for it but equally it isn't a universal solution. TV + media player isn't that bad, but it gets out of proportion when true dumb panels get recommended and you end up with a separate panel, TV tuner, amplifier, media player etc with half a dozen plugs, half a dozen things to turn on and off, and half a dozen remotes."
Well, HDMI has it covered. There is provision to send commands trough HDMI - on/off included. So, how about this?
MediaPlayer -> HDMI -> HomeTheatre -> HDMI -> TV.
There. 3 devices, two cables. Turn the TV on, the HomeTheatre turns on, and so the MediaPlayer.
Pause, play, stop, FF/RW, volume... all this can be set through HDMi. No need to play with dozens of remotes.
Have used this with my mobile and BlueRay player - no HomeTheatre, but...

"Sorry, E-bikes and the like are ......... crap? nonsense? a nun on a penny farthing? (Virgin on the ridiculous)"
Not quite. e-bikes have their place: when You don't want, or can't, pedal. Maybe the hill is too steep, maybe You can't arrive all sweaty at work. Or maybe You are an older person, not strong enough to face that damned last hill.
All of this shouldn't get in the way of someone using a bicycle. Even using the engine on the last hill, the rest of the way could be by human power. Nothing like a liitle exercise, huh?
"Anyone with a discerning ear knows that token-ring is far superior in dealing with n-dimensional frequency flutter..."
I don't know. In my experience, the deterministic nature of token ring takes out much of the analog stage of the music... In order to listen properly one must keep pinging the router - from another device. This way we reintroduce some soul on the signal, with the slight variations in time - due to the ping on the switch.
"Skin effect is present in pretty much any alternating current travelling down a wire, but it's just a description of the fact that AC will travel mostly along the edges of a wire, rather than in the middle.
I'm not sure how it's supposed to effect listening to music, as there's no way to stop it happening, but I suppose that the resistance of the wire would vary slightly with frequency..."
Yes. As the frequency increases, the depth of the wire used to transmit eletricity gets shorter. I don't remember the values, but in a 12 gauge cable I doubt it would be relevant before 100kHz.
"I thought that pwned was an online gamer's misspelling of owned, due to the proximity of O and P on the keyboard. The misspelling is used widely in an ironic manner."
I've read, somwehere I don't remmember, that "p0wned" would stand for "power 0wned". Meaning someone 0wned with great force. Truly f*cked.
Now, I don't know if it was serious about - or if I had four or five too many when I read it...
Take it with two buckloads of salt. :D
"I don't understand this either, why would someone activelly search for specific application, click to install it, in order to watch a specific film..."
Because the majority of users don't know how these things work. We work with this, so it is obvious to us that "Install Netflix to see the movies from its servers" if totally different from "Install this app to see a single (pirated) movie"
From the user perspective, it is the same thing: an app that plays films.
"Also the drought that Sao Paulo and environs is suffering is very odd ."
Not dismissing the climate change, but the São Paulo draught was caused by deforestation. Well, most of it. The government authorized the cut of about 75% of the trees at the... the... head of the river? Sorry, english is not my mother english. The point where the river starts.
It played merry hell with the water cycle. Hence the draught.
But yes. The weather is quite crazy - and getting worse.
"I for one am happy to know that your UK overlords have taken the situation in hand."
No, they didn't. It is against the law to put your hands on the situation.
"Why would they be crashing? Any self respecting driverless car system would include brakes and collision detection."
Because no system is perfect. There are thousands of crazy situations that would make a collision unavoidable.
Two cars, in opposite lanes. Suddenly, a rock falls from a cliff, and get in the way of one car. It can swerve, but this will put it in a front collision with the other.
The other is farther away from the rock - so the front collision will be gentler to both than the collision of the one with the rock. What should happen?
I just made one situation in wich a collision is inevitable - and no driver's fault. With a little imagination we can get a huge number of weird accidents. And given the number of cars on the road, they will happen.
But, I believe, we are reasonably safe taking the "least harm" road.
Take the two before mentioned cars: what should be done?
The decision should be the one that would do the minimum possible amount of harm. I believe we shouldn't base this on gender, age, job... a person is a person.
1) Count the number of persons inside each car.
2) Calculate the action that would pose less risk to the higher number of humans.
It could be one car would sacrifice himself. Or a head on collision could be better - it depends upon speed, road conditions and car model.
The more I think, the more I like Assimov 3 laws. Easy, consistent and quite straightforward. Start factoring gender, age and whatnot... No one would ever reach any conclusion - and all of them would be wrong to someone.
It will not make much difference. Here, in Brazil, we already have this law. I believe about 3 years already.
But they get You by the contract, not by the mobile. Use it, burn it, toss it in the ocean... It's all the same to the carrier. You will pay what was accorded.
Laser is so last year... With a shark this size, we should put a mass driver, with supercavitation projectiles! Can you say "BOOM"?
"It is well established that such sychronisation does take place. Pheromones or something."
They DO synchronize - but not with the moon. It is quite common for the women in a given place to have their periods at the same time. It takes time to happen. It isn't something that we see in just one week, but... Probably pheromones, I don't know. But surely not the Moon.
Think about it: the Moon is the same for all of us. That would keep all the women, on a given region, having their periods at the same time.
"The Walkman app is the best music app on Android! I've trailed most and nothing seems to be as nice to use as the Walkman app"
The Walkman is a good app, but I prefer the "PowerAmp". Walkman plays ok, supports playlists, and so on.
But I like better the "PowerAmp" way. It just works better for me. To each its own? :)
"While InHell may offer some faster CPUs, mainstream consumers do not buy the over-priced top of the line CPUs, only a small group of enthusiasts do. AMD's FX series are very good CPUs and competitively priced. "
One thing that is hurting AMD is the lack of paralelism on software. To ilustrate:
We all know that Intel floating point is better than AMD - no point denying. BUT, the FX series has (about) 50% MORE cores than Intel (Hyperthreading helps a little, but not even close). So, I found out that my FX6300 is about 20% faster than an 40% expensiver (does this word exist?) i5 - doing the official PovRay benchmark. I found out, too, that it encodes mkv very well - giving even an i7 a run for its money.
Problem is: a lot of software is mostly single-threaded - or dual threaded. In this scenario AMD is left behind. This is a problem, since where do we find a benchmark that isn't engineered towards that profile?
"Since rooting the phone and flashing something third-party is outside of the skill set of most users, Android needs to be capable of self-patching."
Not only this, but the whole thing should be like updating a computer. Better still: EXACTLY like we do with our computers.
I can by a (say) Dell, and it would come with a pre installed OS. OR, I could just by an "empty" mobile, and install some OS. THAT would be great.
Even if my choice ended up with "your hardware is 36 months old, it is outside the official support time".
" "- the supported versions like Redhat and SUSE are more expensive to license!"
Are they? Does anyone here actually know the facts (comparing like-for-like) here?"
It is a quite hard question. In the x86 land, Suse charges by socket. Not by memory, cores, threads or whatever. Also, a quick glance didn't show me any limits on use, number of users, load, storage or network usage.
Also, there is a steep discount if you subscribe a 3 or 5 years term.
Example: Standard support (the middle one)
One year: US$ 799 for a two socket machine.
3 years: US$ 2160,00 for a two socket machine.
5 years: US$ 3200,00 for a two socket machine.
This gives you a support 12x5, with unlimited contacts, trough chat, email and phone. It may be pricier than a basic Microsoft server. But it could be used on load levels that would call for an Enterprise Windows Server.
A 4 socket would be double this - as they charge one license for each two sockets.
As you see, not a clear cut answer - and a quite hard one to get.
"Each IPv4 address takes up 32bits whereas an IPv6 address takes up 128bits. That means extra processing power and memory."
The IPv6 header is significantly simpler than the IPv4. One of the goals of IPv6 was to be easier on routers - both by reducing the number of routes and by being lighter to process.
"What I don't get, at all, is why you'd put a complex object/tool for which you've just paid real money into a pocket of your pants,..."
Because it is easy. My left front pocket is dedicated to my phone. Keys and coins go to the front right, the wallet in the rear right and the rear left I use to assorted small papers.
Free hands, no bags and no funny bags. Why wouldn't I do it?
"I take it you disagree with the previous post. Do you have some kind of argument that you're holding back?"
Yes, I do have.
We pay the ISP, for the use of their network to reach the Internet. WE pay for the right to DOWNLOAD and UPLOAD bits. And the price paid was set by the ISP.
Netflix charges US for the right to watch the shows. Netflix buys/rents/whatever the shows, in order to serve them to us.
Netflix, also, buys some form of connection, to UPLOAD/DOWNLOAD bits from the Internet. It is paid for.
And, now, my ISP wants Netflix to pay AGAIN? It is already paid for! In both ends!
"The problem with this horseshit reasoning is people want sacrifices to be made... but won't make them themselves."
Try two children, instead of four, and try walking/cycling whenever possible. Not that hard, and 30 years from now would make a huge difference.
I already walk my last km to work (first four by ferry) - instead of getting a bus. Not much, but better than nothing. No children yet, and planning just one.
Now, your turn.
"Really? So you won't be sending any business or personal sensitive information by email/text either?"
No, I won't. Would You?
"But it's the cloud! Full of fluffy kittens and unicorns and chocolate fountains. Nothing bad can happen there."
The fluffy kittens are dead - all poisoned by drinking from the chocolate fountains (where the unicorns crapped all over).
"From the context I suspect it's something I really don't want to Google!"
It's something You don't want to know. Believe me.
"You mean if you swap the hard disk onto a completely different chipset, Windows not surprisingly won't like it. That's a problem between the chair and the keyboard."
Not quite the chipset: the disk controller. You see, if you change the disk controller, Windows can't boot.
And no, it is not a problem "between the chair and the keyboard". At least, not between HIS chair and keyboard. Indulge me a little:
1) I install a fresh copy of Windows 7. Set my SATA as "AHCI". Once the instalation is done, I will have a "generic SATA controller" installed - this is fine. I can't expect the OS installer to have drivers to hardware newer then itself.
2) I install the corresponding drivers. Let's say that, now, I have "Madureira SATA Controller" installed. Al is fine and dandy.
3) I change the mainboard. The older, with the "Madureira SATA Controller" is gone. Now I have a "New and Improved" one, with a "Niterói SATA Controller".
Windows will blue screen. Why can't it just REVERT to the bloody generic SATA driver? It is included on the installer! I KNOW that it could use it!
At the VERY least, why not (after the first reboot) ask "You upgraded your SATA controller. Would You like to boot into safe mode? (Y/N)"?
It is just sloppy, no excuses.
"That meant every June some lucky sod got to go in and delete 600 email accounts for outgoing students one at a time over a not-especially-fast web based interface."
I believe Gmail accepts text files, to handle some repetitive tasks. I know I could use it to create a large number of users.
Couldn't they be used to update and/or delete accounts? Never looked into it.
"But how does that scale so you can access said email and calendar from multiple machines and/or mobile devices seamlessly? (And effortlessly.)"
"Seamlessly" is easy: IMAP does this for you - and the calendar would be in a server somewhere. When you open Thunderbird it synchronizes everything.
"Effortlessly": I don't know. I mean, you have to install and configure the extension. Not sure how easy (or hard) would be to do it.
Once properly configured, in a UNIX/LINUX world, would be quite easy with NFS and centralized $HOME.
