Back in the 1990's, TV programming for schools (UK) used to have programs for A-level physics that covered this topic. The depth of explanation would be simply to have a cross-section of a various shapes (brick, sphere, aerofoil, triangle, flat panel) all in a wind-tunnel or wave-tank. Then smoke or dye would be added to show how much turbulence there was. The goal wasn't to explain fundamentals like curl, divergence, gradient fields, Eigen-vectors or Navier-Stokes equations, just to give an insight into why a wing provided lift, why a sphere would oscillate and a brick would not even glide.
Even then, all filming would take place in a university or an industrial research lab. It would still be too expensive for a school to provide a wave-tank or smoke box these days, so a computer simulation would be much cost-effective.
It is going to have to be more than just one sub-net. If there is just a "shut-down-the-whole-internet" switch that would probably disable communication between voluntary services and state departments who use the public internet as the cheapest mode of communication. They really are going to have to segment the internet into different bands (international, federal, state, private sector, general public and all the different combinations of communication between them all). It's not going to help if you just disable communication between state and private sector in order to stop people from viewing Youtube and Google searching. It would probably be more effective to have Google servers provide the essential information that people are wanting to read rather than having a state server becoming overloaded.
Yeah, but the 'homer' in Logan's run...when it hit you, would unravel your nervous system..that sounds wicked.
Snake-venom and nerve gas would have the same effect - send you into delerium, hallucinations, convulsions and then paralysis. Not necessarily in that order.
The other bullets were: Tangler, Needler, Ripper, Nitro and Vapour
I can imagine if you vary the explosive strength and velocity of the bullet, it's going to do either explode against walls, shred flesh, knock holes straight through you or turn you into pink mist.
Other movies have had homing bullets in them - one (I can't find the IMDB reference) had bullets that reacted to infra-red silhouettes and thermal images - "it literally had your name written on it" was the quote
A promise to hand over 30% of manufacturing capacity of developed countries to developing countries with no regard to the financial consequences of their own citizens. The only action taken was to maintain the benefits system.
... is that the black hole is composed purely of dark matter, and the intense gravity strips the dark matter (ie. mass/gravitational attraction) from the charged particles (protons/electrons), which then repel each other as jets, while the dark matter just consolidates into the black hole.
I wonder that too - to start growing up in a world where just about every wireless electronic device can send E-mail and play videos - even the cheapest PAYG mobile phone has a 2Mpixel camera and can surf the web.
About 1994, home users could get home internet access through PPP, 2000 ADSL/DSL broadband became available. At the same time, hardware accelerated texture mapping came out with 1280x1024 screens.
It's hard to say - the advances seem to be the same - the biggest advances I have encountered are going from 4-bit EGA to 256-color VGA, and then to 24-bit desktops with hardware-accelerated blitting, as well as going from a CRT to a LCD screen, as well as going from a 16:9 square monitor to a widescreen 1920x1200 monitor. I don't think there is a single CRT monitor in the office block I work in. Going from 56K modem to 1 Mbit cable modem was amazing, but going from 50Mbit to 70Mbit was really that noticable.
A-levels are final year high school courses, not college courses.
Back in the 1980's, BASIC and PASCAL were the preferred choices for high schools. The priority was to teach students about algorithms, conditional statements, loops and recursion and arithmetic instructions. There was some time allocated to teaching students about hardware (CPU, memory, monitors, keyboards and printers), as well as CPU's, assembly language (data transfer and conditional instructions), registers, status bits and interrupts). But more time was spent on teaching students about modern technology - circuit boards, embedded system, washing machine controllers, ATM's and electronic cash registers.
There is only so much you are going to be able to cram into a single high school course. It's not going to be a full-time first year university course covering hardware engineering, software engineering, computing theory and AI. Secondly, it has to reflect the full range of courses available now at college.
Having an offical porn designation.xxx sounds like porn is offically recommended by ICANN, and not just something that happens to take advantage of the Internet.
Filtering domain name strings for the "xxx" string might make writing internet filters work that bit better. Though anyone could still reach a server by typing in the IP address alone. It would probably be better to have an official class A "porn domain range". Even then, somebody could still use a proxy server to bypass the filter.
Then there is the issue of what is defined as porn - obvious things are the nude pictures. But then there are also medical research papers, A&E case reports and news channels. Like that news report on the home-owners who were ordered to cover up a snow-sculture replica of a famous stone carving.
That is what they are doing. Their GPU's have anything between 128 and 960 stream processors - each processor can do a single integer or floating-point operating, with all the processors running at several Giga-hertz each. CUDA allows you to write programs (called kernels) for these processors, with groups of threads being called "warps".
Tricky part, you have to write your code to work around the block architecture of these threads. This is the hard part for many startup software companies. They might be have been founded on the design of some clever algorithms for search engines or image processing. So while at the same time they are refining their technology from customer feedback, they also have to provide customer support, documentation, add new features, re-architect their software as well as adapt to constantly changing GUI environments. Supporting several different multi-core/multi-threading environments (OpenCL/CUDA/GPU shaders/TBB/OpenMP/MPI) becomes a real burden.
I remember this quite from the Delhi Times with an interview with the CEO of an Indian offshoring company; "Americans must do more to continue creating new software companies. If they don't we will be unable to continue taking on more offshoring business work."
I get this problem when doing task parallel addition on a multi-threaded application. A single task that sums the results of a function gets the same result as N threads doing 1 function result each, but different results from N threads doing M function results. Each thread does get an unique set of tasks.
The computer games could be something like "Dance Dance Revolution" or other activity based computer games. I get the feeling that the issue isn't whether they are active or not, but more whether or not they are being creative and creating their own games with their own rules, rather than just having the rules enforces automatically by the computer system.
Like when you played something like "SWAT teams" in the playground, and had an argument who shot who first.
Visit Youtube and watch the literal videos for songs like "The Safety Dance" and "Birdhouse in your Soul", as well as many others. These have scored over 5 million views, so they are quite popular.
Seeing VGA graphics on an 80286 with a 3.5" drive and a demo disk with quantitized 256 color photographs was impressive way back in 1988. By 1991, just about everyone was cursing because it would take one or more boxes of disks to back up a PC using "Fastback".
This is from a UK perspective - anything priced in dollars would be converted into pounds, even when the exchange rate was £1 = $2
Because there are two or three manufacturers of 3.5" floppy disks - there aren't any more manufacturers entering the market, so it is a slow decline. You can still buy 3.25" disk drives as a option for a new PC (+$10) just in case.
It's strange to think that back in the 1990's, we used to think 1.44 Megabytes of storage was extremely generous. Just about every student would have at least one or two solid plastic disk boxes (ten disks each). The most exotic disks would be multi-colored
Now the disk themselves are being recycled into bags and other useful objects
There was story about how a pilot defected to the West using his fighter plane. After he had been taken into custody, the defence analysts had a field day examining the aircraft. They laughed when they saw that the avionics were all composed out of valves rather than transistors. Their amusement turned to shock when they figured out why this choice of valves over transistors - the EMP of a nuclear explosion would fry transistors, but have no effect on valves except to make them glow a little brighter.
Some magazine articles/talks in the 1980's (Z80, 6502, 6809) explained how they worked their way around partially functional CPU's with missing/damaged instructions by using alternative implementations composed from other instructions - Boolean operations could be implemented using arithmetic operators (start with X mod 2 is equivalent to X & 0x01, then work upwards to all the other Boolean operators). This even worked for GPU's!
If your conditional jump instructions were frizzled, then you could calculate the jump address in software using the carry-bit as an index into a table of addresses and use that instead.
I believe he feared that his line-managers would change the configuration settings in some way then turn around and say, "See, he configured all this wrong, and created a whole load of security risks. You shouldn't pay him compensation."
So when he hands the keys to the mayor, he knows that they can't do anything like that.
If you list your E-mail as a registered to a personal domain name in some public forum, that is enough for someone to wait for that domain name to expire and take over. Once control of the domain and E-mail address is gained, anyone can search for that E-mail across all forums and then take over.
I've tried killing off old E-mail accounts in the past. Redirect all friends and family to the new address, while attempting to kill off any subscription based E-mails that arrive. Some are fairly easy - just click on the "Unsubscribe" button at the buttom and it's done. Other sites transfer you to their "manage subscriptions" webpage. You can unselect mailings, but you can't "delete this account and all associated mail communication".
You would just have to send an "oops, I've forgotten my passpord" to the third-party service. With any such service, they will always send out regular circulars and notifications to whatever E-mail accounts are registered with them.
So all a web-site cloner has to do, is find a defunct web-page that is no-longer in use, get hold of the E-mail address, and wait to see what arrives. Maybe they got hold of an old server with disk drives that weren't erased properly.
It was an amazing story. The only part of the cockpit windows not sandblasted into frosted windows was a tiny gap at the top protected by something like a sunvisor. The pilot had to stand up while trying to see where the runway was.
Try typing 'dmesg' if you are using Linux - that will give you the kernel message logs.
There is also 'lsusb', which lists all USB devices, along with 'usb-devices' There are other utilities which allow you to snoop on all USB traffic.
Whenever a device is inserted or removed from a USB socket, it generates a notification event which is logged by the kernel. It isn't going to be too difficult to have those events sent across the network to a central server, or to have a central server to poll each system for the results of 'lsusb' or 'usb-devices'.
Try using a search engine for things like "life insurance", "home security protection" and "fire alarms", then see if web page banners appear or any junk mail related to these topics arrives in your snail-mail box. Or try something totally unrelated like "cattle grids" or "polytunnels" when you rent an apartment in the city.
