I'd imagine they could filter for non-ASCII content - our local ISP does some funny business with viewing webpages in that ASCII text webpage and linked scripts willl download first while images will take ages.
Wonder what happens if you try and use uuencode/uudecode to send data - would it be faster or slower than the equivalent binary data transmission?
1980's - biggest problem with MS-DOS computers was that anyone could delete and overwrite system files, especially in shared environments. It's really hard to believe now, but the standard PC didn't have any distinction between system files and user files except for the read-only, hidden and system file bits. Boot sector viruses were the biggest worry, with sys-admins/help-desks having to continuously fix PC's.
On UNIX side, network worms were the biggest danger.
1990's - Microsoft "fixes" the problem with Windows systems through the use of the "registry", which was to put all important system information in one big hidden place. Separate User ID's and accounts were introduced to given some basic security, but PC owners just give all their new accounts system admin access in order to allow the downloading of games. Neither of these helped to stop the problem of malware.
If anything, having *hidden* compartments/directories/files on a system, only assists malware, by giving it places to hide data. Even deep directory paths and filenames with strange characters like * or # assist in this.
A rough estimate of human vision is 10,000 pixels by 10,000 pixels (going by 100 million receptors in each eye). Most of the detail and colour is perceived in the central area (fovea). Project that resolution in a 120 degree field-of-view and you would get the required resolution. All the high detail would be close up to the observer, while the low detail would be used for distant objects. If everything were constructed out of voxel tiles (ground, air, clouds,trees), like the old platform games, then it would be fairly simply to compress everything.
Maybe the individual points have more data that simply location, orientation and color/transparency/reflectivity. I'd imagine they would have velocity and other material attributes like magnetic strength, stretchiness, brittleness, and viscosity. That would be the way to model an entire world.
They can make quick profits for the time that demand exceeds supply. We've seen that happen with food prices, bio-fuels, and now they are planning to do the same with fresh water (ie drinkable) in the future 20 or 30 years. They expect to see water being traded in the same way that crude oil, basic staple foods like rice and corn are traded.
Oil companies don't own the drilling rigs, as they are too expensive to maintain for the few months that they are drilling well-heads in a new field. Once the hole has been drilled and capped, there isn't much use for that drilling rig. Other times, they will be doing seismic, geological, oceanographic and meteorological studies for the next place to drill. They won't do drilling at any point until they absolutely know that there is something worth drilling for, and that the rig could withstand the local conditions.
Even then, they can still goof-up and underestimate the geology. The Gulf of Mexico accident was caused by the extremely pressures encountered, something in the range of 100,000 PSI+.
Sometimes, there is the occasional bargain if you have the source-code for that project at hand. But for something like an online poker game, if you had what they were looking for, you would make more money have your own site.
You are right, no way is it going to be a long term career. As far as the UK goes, you'd need a minimum of 25K to just survive outside London, and god knows how much to live inside London. Not knowing whether or not you are going to win a contract to feed yourself for the next month isn't practical.
Factors would include the clock-speed of their PC, and the setup of their network/wi-fi router, as well as what else their PC was doing if it were owned by a bot-net.
We did adopt automation - you just don't see it. Western countries concentrated on design technology, ASIC's and CPUs. Eastern countries like Japan concentrated on mass production of things like memory chips and circuit boards.
Back in the 80's, printing any kind of color document would require an entire print shop. You would have to draw up a draft of what you wanted in text (fonts, size, underlining bold) along with pictures. Then a print technician would create copper plate for each page. This would be mounted on a drum, and that page printed. Once finished, another person would dismantle that copper plate (known in the trade as a "stripper"). Come automated newspaper editing systems, laser printers and Postscript, all those jobs just disappeared. There were riots (Wapping in London) over this.
Now, you can use your home PC, create a document, export it as PDF, send it across to the other side of the world, where someone can print it out with exactly the same appearance as you intended.
We did the same with chip and circuit boardd design technology, the low levels tasks are automated allowing the humans to concentrate on the high-level tasks.
It already is . Car-parks in France have automatic pizza making machines - just go up to the screen, press the options that you want, insert some cash, and the pizza comes out at the slot. They may simply just be reheated, but it is a thought. Though there isn't any Domino's Pizza round in these parts.
These were the IP addresses that sent the largest number of packets. Packets coming from Anonymous contained strings like "wikileaks," "goof," and "goodnight". The affidavit was offered in support of a search warrant for the home of an Arlington, Texas couple and their son. They have not been charged yet, but the house was the source of 3,678 packets in about two-and-a-half hours.
That would be true for a lot of industries that are IT related and have "production" pipelines (game/film/TV development, manufacturing). Even help-desk support is going to have that. A help-desk floor would be quiet as a desert for hours. Then someone's network card would fry and jam the whole segment (known as "jabbering"). All hell would hit the fan as every user would call us up in every way possible and ask if we knew the network was down.
Defensive "programming" requires that you have sanity checks on every input that comes your way, log everything that you've done and send the data onwards with timestamps and ID's.
Carnegie-Mellon University have open white papers on "stochastic calculus". There's enough public available material to keep anyone busy for months. No different from fractals and Brownian motion, except that share prices are one-dimensional. Everything else is basically code optimisation from the device drivers upwards.
A search for topics on "stochastic calculus" will be enlightening. Basically it's a form of one-dimension Brownian motion or card-counting with random noise rather than cards. You've got a share price you want to watch because it's constantly moving up and down; it's got an upper and lower bound as well as maximum/minimum deltas, so you know there are good times to buy and good times to sell. The electronic trading system gives you the option of buying and selling and canceling orders at different times in the very short-term future. Like the throw of a coin, the price can go up or down (theoretically, the coin could land on its edge, and the share price could remain static, but there's enough noise in the system to prevent that from happening).
As time goes on, the probability of a lucky streak or a straight run of downs or ups becomes infinitely small. So the trading algorithm has to determine the optimum times of buying and selling. The system can send in an order to buy at time t0, and another order to sell at time t1. If at some time in-between, the price falls, the orders are canceled, otherwise if the price exceeds the target profit, the shares are sold anyway. Because the computer systems are so closed to the actual trading system, all of this can happen thousands of times faster than any remote punter could.
Going by previous discussions here, they've got 1000 IP addresses which probably are DHCP clients owned by bot-nets, which in turn are communicating via distributed command and control through proxy intermediates using encrypted channels. That's going to be fun chasing up. A simple whois will give them the ISP, but how are they going to identify the actual PC that was in use then?
After 24-hours of the event, they could have watched those IP addresses, and did some traffic analysis on the hosts they connected to. Then they could follow the communication chain upwards.
And the system becomes unusable due to all the file logging going on. Whenever I upgrade the OS on my system, I always like to do an audit of where all the file space has gone. First of all, backup all project data, then remove them. Remove all download files (rpm's, zip's, exe's, bz2's, webpages) and personal files). With all those gone, there shouldn't be any considerable file space used, yet gigabytes of space were still used...
As someone who's done rendering and animation, and used the file browser to preview images, I found about 2 Gig's of filespace had disappeared just from thumbnails alone. A 60-second animation took around 3000 frames, or 3000 images. After a good few number of projects and reference photographs, that's a whole load of data space gone.
Windows XP also maintained log files that are updated as the system boots up - one for the hardware after power-up, another for XP device drivers, and another for applications. If these log files became inconsistent (through a crash and reboot), they wouldn't clear. It wasn't apparent whether they had to be cleared manually, but those files just got bigger and bigger over time. This would jam up disk defragmentation as well. Found about 6 Gigabytes after 5 years. Also, whenever you update your web browser, while the old version may be deleted, the cache directory isn't. That was another chunk of diskspace lost.
Every commercial company or large public sector group that I have worked for, has insisted on having identical systems throughout the premises, thereby eliminating the expense of having multiple platforms to support.
One IT manager I knew, was present at the arrival of new PC's being delivered by container truck. Unfortunately, as they were IBM PS/2's, and completely different from the standard PC's that the received, the whole batch was sent back.
Oil companies in Scotland used to do that in the 1990's at least. The local computer club alway had stories of engineers and consultants visiting their sites on commerical business, and seeing large refuse skips filled to the brim with PC's, coaxial cables (The original yellow and blue LAN cables), ribbon cables, monitors and PC chassis. All perfectly functional, but the companies always wanted to have the latest technology.
My last employer had a Dell contract. It's more than just the cost of machines, it covers the cost of replacement of whole batches of PC. Our technicians used to do PC swapping if anyone's PC did go bad. They did basic component swapping (monitors, memory chips, graphics boards, CPU's) to repair things, anything else like power supplies or motherboards would just be sent back to Dell. Maybe once a month, they would have handful of Frankenbox broken PC's and monitors left.
The fun part would be if they were around the wavelength of the photons. Then you would get diffraction grating patterns and rainbows. If they are going to make a transparent PC, it would be really useful if the material could actually change color according to temperature. Then you could see how well the cooling system is working.
If you model it geometrically in one, two or three dimensions, you will end up with a boundary interface between the two groups. Each group will expand outwards through the unconverted until they encounter those that have been converted.
Visualized in one dimension, you get alternating bands of the two groups. In two dimensions you get circular dot, and in three dimensions you get spheres. Practically, it would look like one of those voting maps of a country.
Even a cheap PAYG mobile phone has bluetooth and voice recording capability (eg. ZTE). Using a laptop bluetooth dongle it is possible to set the phone to record audio to files and stream off the audio files through Bluetooth from a distance of 10+ metres. No mobile phone network is required. The maximum range really depends on the strength and sensitivity of the other party. Since there is around 64 Mbytes of internal memory, so it really makes me wonder what it is going on inside a device like that.
