It’s the mid 1980s. You have a file want to transfer from one computer to another, but these machines are vastly different. Both have RS-232 serial. That might help, but you have no common protocol to transfer that file.
A frog comes to your rescue.
Seriously though, the Kermit file transfer protocol is one of the most widely ported piece of software out there – and for good reason.
explored the ubiquitous transfer protocol on two CP/M capable machines, and an IBM PS/2 luggable running MS-DOS. The Kaypro II machine is plenty common, but the Intertec Superbrain (another Z-80 based machine which ran CP/M) is a recently restored gem. Douglas demonstrated the compile time of the 8080 build of Kermit on his Superbrain, which didn’t take much time at all. Then he transferred some files from the IBM over to the Superbrain like it was nothing. The best part i that Kermit is still a viable data transfer method today when moving information to and from legacy machines.
“This exhibit shows the Intertec
Superbrain and its historical role in file transfer technology. In 1981
Columbia University pioneered the application of microcomputers for
enabling students to transfer their minicomputer and mainframe work
files to and from their own personal floppy disk storage. The first
client version of Kermit was implemented on the Intertec Superbrain.
From that point Columbia University fostered a grand project that spread
Kermit to nearly every execution platform in existence. It might be
said that our downloads and uploads we do today over the Internet owe
some respect to the Superbrain in its first file transfer to
floppy. This exhibit will include: a Superbrain QD computer recently
restored to operation, highlights of the restoration effort, unique
aspects of the Superbrain’s design, the Superbrain’s role at Columbia
University as the first Kermit client platform, period development
tools, and a build of an early Z-80 assembler version of the Kermit
client that I’m making. It will also demonstrate Kermit file exchange
using the Superbrain and possibly running the “built” Kermit client
along with a presentation of noteworthy Kermit details, history, and its
significance to today.”

Below you will find a full list of past Halloween costume tutorials I have made in the last few years. Most of the tutorials come in video format and included a full list of materials and detailed instructions on how you can re-create the costumes yourself. I will be posting a whole new set of costume tutorials starting tomorrow, but I hope this helps inspire your halloween costume in the meantime. Happy Crafting!
Pulsed power is the science and technology of accumulating energy over a relatively long period of time and releasing it very quickly, thus increasing the instantaneous power.
Steady accumulation of energy followed by its rapid release can result in the delivery of a larger amount of instantaneous power over a shorter period of time (although the total energy is the same). Energy is typically stored within electrostatic fields (capacitors), magnetic fields (inductor), as mechanical energy (using large flywheels connected to special purpose high current alternators), or as chemical energy (high-current lead-acid batteries, or explosives). By releasing the stored energy over a very short interval (a process that is called energy compression), a huge amount of peak power can be delivered to a load. For example, if one joule of energy is stored within a capacitor and then evenly released to a load over one second, the peak power delivered to the load would only be 1 watt. However, if all of the stored energy were released within one microsecond, the peak power would be one megawatt, a million times greater. Examples where pulsed power technology is commonly used include radar, particle accelerators, ultrastrong magnetic fields, fusion research, electromagnetic pulses, and high power pulsed lasers.
Pulsed Power was first developed during World War II for use in Radar. Radar requires short high power pulses. After the war development continued in other applications leading to the super pulsed power machines at Sandia National Laboratories (above).
Triple-threat – lasers, magnets and a big pinch – sparks hope for fusion Nature News & Comment 30 December 2013
The Z machine at Sandia National Laboratories in New Mexico discharges the most intense pulses of electrical current on Earth. Millions of amperes can be sent towards a metallic cylinder the size of a pencil eraser, inducing a magnetic field that creates a force — called a Z pinch — that crushes the cylinder in a fraction of a second.
Since 2012, scientists have used the Z pinch to implode cylinders filled with hydrogen isotopes in the hope of achieving the extreme temperatures and pressures needed for energy-generating nuclear fusion. Despite their efforts, they have never succeeded in reaching ignition — the point at which the energy gained from fusion is greater than the energy put in. But after tacking on two more components, physicists think they are at last on the right path.
Located in Albuquerque, New Mexico, the Z Machine is the worlds largest X-ray generator. When discharged, for a brief period of about 70 nanoseconds, the Z machine releases 80 times the electrical output used by the entire planet. One of its main objectives is to study the conditions of extreme temperature and pressure, with the hope of solving the practical difficulties in harnessing the power of nuclear fusion. The temperatures reached in the Z Machine (up to 3.7 billion kelvins) are well beyond those required for standard hydrogen, deuterium and tritium fusion. This could potentially allow for the fusion of light hydrogen atoms with heavier atoms, such as lithium and boron. These fusion reactions would not produce neutrons, which means they would not produce radioactivity or nuclear waste, which would provide a far cleaner and more efficient source of power than is currently available.
Spotify has been playing me a bunch of old Squarepusher recently and man! Blast from the past! Prompted me to check out some of his recent work and apparently he just came out with a new album last month of music written by him and performed by ACTUAL ROBOTS?? 1) This song is so good 2) This video is so cool 3) ACTUAL. ROBOTS.
The Z machine is the largest X-ray generator in the world and is designed to test materials in conditions of extreme temperature and pressure. It gathers data to aid in computer modeling of nuclear weapons.
Z releases 80 times the world’s electrical power output for about seventy nanoseconds, with a maximum output of 290 terawatts. For comparison, that’s enough to power 20 trillion light bulbs. The equivalent of 290 lightning strikes at peak power. As many kilowatts as the number of stars in our galaxy.
The machine has reached a peak temperature of 3.7 billion degrees Celsius, which is more than 200 times the core temperature of the sun (Notably the Hadron collider has achieved more than a thousand times this temperature). It has also propelled small plates at 34 kilometres per second, which is a hundred times the speed of sound.
