Amazing what cool stuff is available these days
Sorry, couldn't resist. I'll get me coat. The one with "Get thee to a punnery!" in the pocket
But unlike squirrels, we never forget where they are
Please note the sarcasm I intended with "quite a bit of sense". ;-)
I do not buy into his anarchistic ideal. I do not like over-intrusive government either, the best we can manage in the sublunary is some compromise.
Lower crime rates might also depend on what you consider crime. If you do not consider shooting somebody who appears to be threatening a crime, then guns are not a problem I suppose. I do see shooting people because they appear to be threatening as a crime.
Gun availability in itself need not even be the core of the issue. The core of the issue on the astronomical gun related killings may have something to do with a culture that has less problems with violence in movies than with sex.
“More guns in the hands of more people leads to a lower crime rate."
What a pity Cody, up until that remark you were making quite a bit of sense!
I guess he has been indoctrinated by the USA government and gun lobby more than he realises.
until I can fit my 85mm F/1.4 Carl Zeiss Planar to my phone (fits my EOS through an adapter). My smartphone is fine for every day shots, but in low light conditions (theatre, animals around dusk, astronomy) I need to catch more photons than the puny lenses of camera phones can catch. Simple physics: double the aperture in diameter for a given pixel count, double the signal to noise ratio (when photon-noise limited). Nothing can alter that. What could change is the maximum electron density per unit of area on photosites of CCDs or CMOS chips. That would allow better dynamic range on small photosites, provided the number of photons captured allows that increase in dynamic range.
This does not mean I do not applaud the improvements in camera phones. They have come a long way from being a barely usable gimmick to a pretty decent instrument for everyday photography. The only downside is the sheer number of selfies produced. Finally, I would not like to carry the bulk of said 85mm lens (close to 900 gr) on a daily basis, of course.
Your OS, hey? Should it go? Hey? Should it go? Hey? Know what I mean, know what I mean? Nudge, nudge, wink, wink!
Much as I would like a chin-wag over claret, even with the chinless, or those endowed with more chins than strictly necessary for the support of a face (doffs hat to Leslie Charteris for the latter phrase), I am afraid I wont be able to hop over the Channel for that.
I somehow picture a record sponge in the fossil record, holding a mosasaur in its deadly embrace.
Could easily compete with "correct horse battery staple" for a pass phrase :)
Indeed, although we use Foul Ole Ron as a source of pass phrases (but NOT "Millennium hand and shrimp").
somehow came into my mind. I wonder why?

Thumbs up for fessing up!
I do not doubt that <Austrian accent>You'll be back</Austrian accent>
In my experience hiding memory complexity is a mixed blessing. To gain maximum performance I need to understand the architecture the code runs on, to avoid costly operations, as others have said. I will get my code up an running sooner, but it will not necessarily be as fast as hand-tuned code. Where I do see use is in getting more-or-less machine independent code up and running quickly. If it does not run fast enough, you can then tune it to get the most out of the hardware and reduce costly copying from one part of memory to another, and so avoiding bandwidth and latency problems.
Nothing beats better bandwidth and lower latency, of course, but that is something the hardware guys must do for us software guys (and I know they are working on it). If the GPU and CPU truly share memory (i.e. the memory is physically unified), many difficulties will drop away, but that is something to dream about, for now
Agreed. Any of my students presenting this kind of data like that would get points deducted (and/or instructions on how they should present these data).
And cloud, of course, but sites like slooh are just great for this. Showed the kids the transit of Venus two years back by logging onto slooh on the smartphone. It's just great what IT has brought us.
The chances of funding are proportional to the effort put into the (b)ac(k)ronym. Politicians gladly fund a project named OSIRIS-REx, however tenuous the connection between name and purpose, they might go for Yet Another Asteroid Bashing Attempt (YAABA) because you can at least pronounce it, but Probe For Planetoid Research (PFPR) stands little chance
I heard someone at MS proposed
Windows 8.1 Falls On Sword Silently
as a final option on the roadmap, instead of FU2, but management didn't like the acronym.
How do you switch on large, friendly letters?
Indeed, frequently range clearly designed with Agnes Nitt (a.k.a. "Agnes-who-calls-herself-Perditax") in mind. It might be a problem to filter out the occasional thud of a falling bat from the recording
The only way to be certain your files cannot be inspected on Dropbox - or any
service like it - is to NOT put them on there in the first place !
Or use a one-time pad encryption, if you do want the option to share files. A one-time pad is fully uncrackable. Getting the key to others by a secure channel is a problem of course.
If you do not want to share your files, you could stick them in a locked filing cabinet in a disused lavatory with a sign on the door saying "Beware of the leopard", in a basement, in the dark (the lights had probably gone (So had the stairs)).
So often it is some trivial component that fails. Best of luck next time
Still not enough RAM!!
I know, I know, us compute guys are never satisfied. You give them more than 640 kB? They want more than 4 MB, you give them 16MB? They want 256MB! You up your game to 16 GB, and some knucklehead wants double that, and so on, and so forth.
Having frequently run out of memory on a 64 core 512GB compute server (with 384 GB Fusion-IO card), the R3 is still not for me. Still looking for a distributed-memory solution for our problem. Not trivial.
Neat in itself, but I remember the problems somebody had whenever he put a cuppa in front of his Apricot keyboard, blocking the line of sight between keyboard and computer. The key idea behind fibre optics is that you protect the optical path from intrusion by smoke and mirror. WIFI works better because the long wavelengths diffract around objects rather better than visible light or IR.
In conclusion, though the data rate obtained is good, I am slightly underwhelmed.
I would suggest the key issue is that there are two specifications of the length of the data, not one. One has to wonder about the reason for this redundancy (it may be useful in another context, I do not know enough about the SSL libraries and protocols), but here it causes a problem. It could be used to check for malformed heartbeats, of course, but the moment you store information in two places, and fail to ensure consistency of the information, you can get into trouble.
Using a calloc rather than malloc to allocate the space for the incoming heartbeat data based on the SSL3 length field and then storing the payload_length size chunk in it (after checking payload_length<=SSL3_record.length) should have avoided the problem, I would think. Of course calloc could be a touch more costly than malloc, but in the context of security (or indeed delays in the network) I would think this hardly figures in the grand scheme of things.
Just my tuppence
Still, no worries, she'll be right!
Next look out for a rock in the shape of the Counterweight Continent.
As far as I understand it, if I develop a piece of code which infringes patents (as Google allegedly has), I do not necessarily require a licensing agreement. If I sell a product with such software on board, I certainly do. This might be the reason MS is not going after Google (or maybe there are secret agreements, where's me tinfoil hat!!)
This could provide a cheap way for students to learn MPI computing, although you can run MPI on a shared-memory architecture (but without same the penalty of communication overhead as in clusters). Using a "nano-cluster" like this you can have student mess about without interfering with the workloads of the big "production" clusters of the university, or, as the students see it, without production work interfering with their projects.
Too expensive for me, alas. I will just retain the fond memories of being allowed to stay up late as a seven-year old to see men step out onto the moon on a little black and white TV. Greatest event in my life until then.
Every single boy at school wanted to become an astronaut that day.
Good to hear the European Court make such a sensible decision
I'll raise a glass to that
You could have started the piece with DON'T PANIC in large, friendly letters. Good selling point, I read somewhere
I'll try to get Win 7 working on my old (8.5 years), decrepit, but still functional VAIO SZ2XP/C, which should be able to run it (with some drivers I have unearthed) later this week. Through a university license I can get a win 7 pro update cheap, so it is worth a punt. Should it fail I will wipe my last Win XP install make it single boot again (but this time with OpenSUSE Linux).
A lot of interesting activity has been visible on the sun the last few weeks. Great to watch either on various web-sites, and even better with a solar scope.
The websites like GONG (http://halpha.nso.edu/) and the like are ideal for those without solar scopes, and/or with British weather.
In all seriousness, I do not know enough about everything that has happened in the Ukraine to take any side. Various sources contradict each other, and I am left with the cynical baseline thought that I trust no politicians. There are evidently thugs on either side, there are people with little or no regard for what "the people" really want jockeying for power on either side, and many, if not most ordinary people get squeezed in the middle. A summary of the politics of power struggles that holds true all too often.
Let's not bicker about who invaded who!
A pointless exercise, as every nation that has ever thought of itself as or has aspired to be a Power (capital P mandatory) has behaved pretty badly during its history
Indeed, as the late, lamented Douglas Adams stated succinctly in his summary of the summary of the summary:
People are a problem
Rule 50: My main computers will have their own special operating system that will be completely incompatible with standard IBM and Macintosh powerbooks.
is easy to fulfil: just use an old CDC 7600 with its 6 bit bytes and ten byte words, and an OS that is not so much "not user friendly" as "user hostile." The only downside is that it is slower than your average smartphone.
As an alternative, you could up the voltage on all the i/o ports to fry any PC or macbook attached to it without authorization, inspired by the idea of the etherkiller
The only sane reason for spying on friendly governments was of course given by Lord Vetinari, who states that spying on friends improves mutual understanding and therefore promotes friendship even more.
There is of course another school of thought who points to the bablefish, which by removing barriers in communication between species has lead to more and bloodier wars than anything in the history of creation, but it could be argued that the opposing sides in these wars weren't friends to begin with.
I gather a recent report has shown that no terrorist was caught and no act of terrorism prevented as a result of the blanket snooping program by the NSA. I really do not see how snooping on a head of a friendly government helps fighting terror.
more data needed (as they indicate). If correct, it gives a clear indication that dark matter is actually there, and not (only) an error in our understanding of gravity. The main reason to postulate the existence of dark matter was the lack of visible mass needed to explain both the orbits of gas and stars in galaxies and gravitational lensing. An alternative theory would be to postulate our law of gravity is wrong (which is also hard to reconcile with other observations).
I await more data eagerly
which, chemically speaking is odd
I'll get me coat
I never realised the humble USB plug was a quantum computing device, but this revelation makes perfect sense. I am sure I have noted the orientation flipping on certain devices (top -> bottom transitions and vice-versa), but always attributed this to Murphy's Law (a.k.a. High Auditor Activity, as can be confirmed by the usual garden hose test). The two explanations are of course not mutually exclusive.
Our galaxy is between 1.0 and 1.5 trillion solar masses, so El Gordo is more than 2,000 times heavier
Needs a high fibre diet and more exercise
do they also make chatty doors? You know, for Elon's spaceship? The ones that you can tell are about to open by the intolerable air of smugness they suddenly generate?
Love his Yak milk from 600 years ago. Still fresh too
if you don't observe it consciously
I'll get me coat, the one with "What is life?" by Erwin Schrödinger in the pocket please
Or should that be "the alleged jury"
If payment in bitcoin is accepted by him (i.e. some arbitrary real or virtual item of no intrinsic value is nonetheless accepted by mutual agreement to represent some value), but he then does not count bitcoins as money (which can be defined as some arbitrary real or virtual item of no intrinsic value which is nonetheless accepted by mutual agreement to represent some value)
Legal wrangling about words without looking at their meaning. Par for the course in court, I suppose
Great, looking forward to that. I'll get my kids to see it too.
