Back in the early 80's, when I was working for a UK company called Laser-Scan, mostly doing digital cartography, we had a request about using a laser to brand bar-codes onto pigs as they went into the abbatoir. I can't remember anything coming of it, though.
The main health hazard is attached to the gaseous waste products. They contain not only carbon monoxide and sulphur dioxide (both highly toxic) but also a number of carcinogenic compounds such as phenanthrene and others. To discharge these into the air is impossible. It would cause the tolerance level to be exceeded for several miles around the reactor.
It is therefore necessary to collect the gaseous waste in suitable containers, pending chemical detoxification. Alternatively, the waste might be mixed with hydrogen and filled into large balloons which are subsequently released.

"Accidentally deleted" probably means "we had a hardware failure and we're too cheap to recover everything".
No: "Accidentally deleted" means that a technician was working on a backup storage system,
but also had a window open to the primary, and reformatted the wrong one.
According to this posting at ADSLGuide (which might be the text found at one of the links
in the announcement linked to above),
the initial problem was exacerbated by the technician trying to create a new volume
of the same size as the one he had just deleted. This left a load of orphaned
i-nodes on the second and third volumes.

Introduction
The recent discovery of coal (black, fossilized plant remains) in a number of places offers an interesting alternative to the production of power from fission. Some of the places where coal has been found show indeed signs of previous exploitation by prehistoric men, who, however, probably used it for jewels and to blacken their faces at religious ceremonies.
The power potentials depend on the fact that coal can be readily oxidized, with the production of a high temperature and an energy of about 0.0000001 megawatt days per gram. That is, of course, very little, but large amounts of coal (perhaps millions of tons) appear to be available.
The chief advantage is that the critical amount is very much smaller for coal than for any fissile material. Fission plants become, as is well known, uneconomical below 50 megawatts, and a coal-driven plant may be competitive for small communities (such as small islands) with small power requirements.
Design of a Coal Reactor
The main problem is to achieve free, yet controlled, access of oxygen to the fuel elements. The kinetics of the coal-oxygen reaction are much more complicated than fission kinetics, and not yet completely understood. A differential equation which approximates the behaviour of the reaction has been set up, but its solution is possible only in the simplest cases.
It is therefore proposed to make the reaction vessel in the form of a cylinder, with perforated walls to allow the combustion gases to escape. A concentric inner cylinder, also perforated, serves to introduce the oxygen while the fuel elements are placed between the two cylinders. The necessary presence of end plates poses a difficult but not insoluble mathematical problem.
Fuel Elements
It is likely that these will be easier to manufacture than in the case of fission reactors. Canning is unnecessary and indeed undesirable since it would make it impossible for the oxygen to gain access to the fuel. Various lattices have been calculated and it appears that the simplest of all, a close packing of equal spheres, is likely to be satisfactory. Computations are in progress to determine the optimum size of the spheres and the required tolerances. Coal is soft and easy to machine, so the manufacture of the spheres should present no major problem.
Oxydant
Pure oxygen is of course ideal but costly; it is therefore proposed to use air in the first place. However, it must be remembered that air contains 78% nitrogen. If even a fraction of that combined with the carbon of the coal to form the highly-toxic gas cyanogen, this would constitute a grave health hazard (see below).
Operation and Control
To start the reaction one requires a fairly high temperature of about 988oC. This is most conveniently achieved by passing an electrical current between the inner and outer cylinder (the end plates being made of insulating ceramic). A current of several thousand amps. is needed., at some thirty volts, and the required large storage battery will add substantially to the cost of the installation.
There is the possibility of starting the reaction by some auxiliary self-starting reaction, such as that between phosphine and hydrogen peroxide. This is being looked into. Once the reaction is started its rate can be controlled by adjusting the rate at which oxygen is admitted. This is almost as simple as the use of control rods in a conventional fission reactor.
Corrosion
The walls of the reactor must withstand a temperature of well over a 1000oF in the presence of oxygen, nitrogen, carbon monoxide and dioxide, as well as
