While this next one is an elaborate device, it is based on the same theory (but draws much more precise ellipses). (Chalk would be placed in the holder on the left end of the cross-beam.) Here is a simple trammel dating from the late 19th century and probably used in the classroom. The museum has eight ellipsographs in its mathematics collections. There are also much more intricate devices that will draw ellipses and they all fall under the title of ellipsographs. Trammels are deceptively simple machines that produce something profoundly mathematical. That's right! The trammel is a device for drawing ellipses! You can go to YouTube and type in any of the names above and you will find videos and animations of this wonderful little device in action ( this one is fun), and even directions for making your own if you are handy. Don’t you think it looks good?īut why have I linked these two items, the "do-nothing" machine and the ellipse? The answer is in the mathematical name for the machine: the elliptic trammel. You can draw a perfect circle simply by using a single pin.Įven though I had known theoretically how to draw an ellipse since I first learned about conic sections, I had never actually done it! I was surprised that it worked so well right out of the box. Notice in my creation below that the total length of string does not change, so the distance from the two pins (foci) to the pencil is always the same (r1+r2 in the diagram above). The easiest way to do this is to draw one (please try this at home-you will feel a great sense of accomplishment) using a piece of string, two pushpins and a pencil. So what exactly is an ellipse? Apart from its mathematical equation, which you can look up if that vital piece of knowledge escapes you, it can be defined very simply as the set of all points whose combined distance from two points (the foci, F1 and F2 above) remains constant. You may even recall that a circle is a special case of an ellipse where the two foci become one (see image below of an ellipse and all its relevant measurements). Archimedes explored these geometric objects at length and was the first to give us some idea of their uses. The conics are the circle, the ellipse, the parabola, and the hyperbola. You remember those, the four curves that arise when you cut a cone with a plane. Envision yourself drawing conic sections. Now I want to take you from your halcyon days of childhood toys to the more capricious days of ninth- or tenth-grade Algebra II class. He gave us, among other amazing things, the Archimedes screw, still used in many developing countries to raise water the theory of density, where he famously-though maybe not actually-cried "Eureka!" when he discovered while soaking in the bath that King Hieron II's crown was not made of pure gold and the legendary burning mirrorsand other defensive works that kept the Romans out of Syracuse for three years during the Second Punic War. I mean, how sad? Why give a child a toy that by its name has no intrinsic value? Why not call it the "what does this do?" machine and let them explore it until it has some meaning? To me, it is an elliptic trammel, often referred to as the Trammel of Archimedes after the ancient Greek mathematician Archimedes of Syracuse (c. 287 BC – c. 212 BC).Īrchimedes is my personal math hero. As a child, you may have played with a simple wooden toy called a "do-nothing" machine or simply a "grinder."Īs a mathematician, I find that name a very poor choice.

Tracking your freelancers’ time keeps you up to date on the tasks they are working on, provides you with a detailed progress report, and gives you the ability to send their work along to your clients to make sure they are heading in the right direction with the assignment. This feature assists you with both billing and payroll. Without computer tracker software, money may be lost to employees who do not track the correct amount of time they are spending on work. The tagging capabilities of the time tracking software tell you what each user has been working on and that they are billing you for the correct amount of work. ManicTime allows you to track what projects your freelance or remote employees are working on and, more importantly, how much time they are spending on that task. To keep your business running smoothly, it helps to be able to keep all your employees accountable for their work. When these employees are not physically located in the same space as you or the rest of your team, it can be difficult to track their progress on essential projects. Time tracker software is also beneficial for businesses, large and small, that work with freelancers, contract employees, and remote workers. Studies have shown that we work better when we know we are being tracked, so ManicTime can help keep you on task and working effectively. Individuals who are self-employed may find that using ManicTime increases their productivity. Our time management software can be downloaded onto your individual computer, or you can choose to have it on the computers of your employees. Who Can Benefit from ManicTime Time Tracker Software This keeps all your essential data in one place so that you can continue to improve how you do business in concrete ways. More than that, ManicTime can be integrated into many software applications that you may already be using. Data from ManicTime is stored locally, unlike many other time tracking software applications that store data in the cloud. Since ManicTime is located on your server or your individual computer, you don’t have to worry about your sensitive data getting out as the result of a breach or a hack. ManicTime can be used on and offline, making it easy to work from wherever you are. This tracker allows you to compile information regarding computer usage throughout your company to see what employees are spending their time on, what projects are being worked on, and what applications are being accessed. If you are using ManicTime throughout your business, you can download it on your internal server and install it on numerous computers, as the licenses are issued per user. Outlook 2007 w/Enterprise Server (plus Taglocity, Xobni, LinkedIn toolbar, WorldMateLive toolbar, Evernote Clipper, Sender TimeZone)Īnd probably a bunch more "critical" programs I'm forgetting.ManicTime is a time tracking software that is downloaded onto your machine. Google Apps (Mail, Voice, Chat, Sync, Earth, Picasa) This is what I have running to get things done in my world: Just a place to read, research, write and draw (oh, and playfully terrorize the cat.) Sometimes simplicity is the best technology. I don't need anything more fancy or high end. This is pretty much an ultra clean setup with just the basics. Pieces are moved by going into an adjacent, unoccupied space, as well as by jumping over pieces–your own or your opponents’–if there is a unoccupied space immediately beyond players are allowed consecutive jumps on the same turn, but a jump and a simple space-to-space move are not allowed together. The object of the game is for players, starting in the corners, to move their pieces across the board, ending up in their opponent’s starting positions. Two things make HALMA unique: 1) the number of pieces used at the start of the game depends on the number of players and 2) although players may move their pieces by jumping over opponents’ pieces, the jumped pieces are never captured nor removed from the board. HALMA is played on a flat square board with 256 spaces (16 x 16). since the Parker Brothers version in 1961.Ī more colorful than usual Halma gameboard, ca. But HALMA is still played throughout the world, though it has not been produced in the U.S. As a result of the conflict between Bradley and Horsman, Bradley released a revised rendition of HALMA in 1889, with the made-up name ECKHA, stating: “owing to the fact that certain parties claim to possess exclusive rights to the use of the word “Halma,” …(and) in order to avoid any controversy, we now designate that game by the new name of “Eckha.” ECKHA never became popular. According to Milton Bradley, “(Halma), while published by us, went to nearly every part of the civilized world….” Horsman, calling itself “The Halma Company,” claimed ownership as well. Horsman, produced the game into the early 20th century. Monks) in New England in 1885, another American company, E.I. Although Milton Bradley said it had acquired the strategy game from the original inventor (G.H. HALMA is the only internationally-recognized classic game from the 1800s known to have originated in the United States (though some books incorrectly report it was invented in England). Other kinds of accelerators, including Intel’s Xeon Phi and various DSPs have also found their niches and could gain more adherents. GPU accelerators are being used for raw computation as well as for product design, simulation, and rendering, radically bringing down the cost of what manufacturers can do to virtually design and test products. The manner that compute coprocessors are being deployed is shifting around in some cases as, for instance, FPGAs are being embedded in network interface cards and switches. There are many ways to improve the performance of applications, and as is usual, the national supercomputer labs and large financial services and energy companies are leading the way in the deployment of various kinds of coprocessors for the distributed applications they run on their clusters. We are particularly interested in a number of key technologies, such as GPU, FPGA, and other kinds of accelerators. To that end, EnterpriseTech, in cooperation with my industry research firm, Gabriel Consulting Group, is surveying users in large enterprises to try to get a sense of which technologies are important to accelerate applications. Equally importantly, we want to grasp why various technologies are not being adopted by specific industries or classes of customers. Here at EnterpriseTech, our mission is to try to understand the technologies that large enterprises are deploying for competitive advantage and to discern why they are chosen and how they are deployed. Many of them never make it to the corporate datacenter, while others get there eventually. The great thing is that there is no single way to gain competitive advantage, and that researchers in academia, government, and industry are constantly creating and testing technologies. More times than not, that means being out there on the leading edge with new hardware and software technologies, or innovative ways of creating software. Decades later, computing in its various forms is the foundation of the modern corporation, and companies are still looking for new ways of gaining an advantage. Since 1987 - Covering the Fastest Computers in the World and the People Who Run ThemĮnterprises are always looking for an edge to use against the competition, and information technology was created initially and specifically to be that edge.
Decades of experience, along with a greater preparedness to employ devious tactics, gave the Soviet Union a distinct ‘head start’ when it came to espionage. The KGB assumed responsibility for both domestic security and foreign intelligence. The Soviet Union maintained its own agencies, most notably the KGB (Komitet Gosudarstvennoy Bezopasnosti, or ‘Committee for National Security’). The CIA also supported US foreign policy by providing support, funding and equipment to anti-communist leaders and groups abroad. The CIA’s Cold War activities ranged from general surveillance of suspected foreign agents, to the deployment of agents abroad, to illicit operations like assassinations and human experimentation. For example, in the United States these functions were carried out by the Central Intelligence Agency (CIA). Companies in the United States may be providing the United States military with some of the elements that go into making an airplane invisible to radar.ĭuring the Cold War both superpowers (and many other major nations) maintained government agencies related to espionage (spying) and intelligence gathering. (This is a secret process used to make United States military aircraft invisible to radar). An example of this is the companies who produce the material used by the United States Air Force to make certain aircraft “stealth”. Secondly, the company’s information may be used by the military and is secret due to its final use in the military. Countries spy on other countries (and the companies in that country) to get an economic advantage. If that information is obtained by the spying country then the employment jobs and work generated from that information may go to another country. This may also involve the spy attempting to learn information about the country’s own intelligence service, its operations and personnel within that intelligence service, an example being the Russian Intelligence Service (SVR) may be interested in the people who are employed in the United States Central Intelligence Agency (CIA).Įconomic Secrets – This may involve information within a company that is one of a kind or unique to the world. Government Secrets – This may involve information about a government’s secret approach to another country or to specific issues like the environment or foreign spending. The military information may involve secret defense planning by a country’s military, its methods of operations, its personnel, its secret specialized equipment or weapons in use by that military, or the military’s capabilities in any location of the world. Military Secrets – One country’s military secrets may be of interest to another, especially if the two countries have a history of conflict, (not being at peace and they may share a border). These countries conducted espionage against each other and other countries to get information on subjects such as military secrets, government secrets or economic secrets. Espionage was a key tool of the Cold War and helped both superpowers (the United States and the Soviet Union) in their policies to expand their influence.

Process of Sending and Receiving Files Through BitTorrent – Source: įurthermore, the protocol is praised for lowering bandwidth usage and helps to prevent localized spikes in internet traffic. Using this means of file sharing, basic computers like laptops and home PCs become capable of efficiently replacing powerful servers and distributing files to several recipients simultaneously. Rather than downloading files from one single server, the BitTorrent protocol allows users to join a “ swarm” of hosts to simultaneously upload/download portions of data residing on peer machines, then compile them into a full copy of a given file. In order to send and receive files, users should install a BitTorrent Client (a program that allows peer-to-peer file sharing using the BitTorrent protocol) on its end-user, internet-connected computer. How Does the Process of Sending and Receiving Files Through BitTorrent Work? We have compiled a list of the best VPNs for torrenting for you to read so you can choose the best one for you. You need to be choosing VPNs that are based in safe jurisdictions and have solid no log polices. Remember that all VPNs are not created equal, you should not be using a VPN service based in a country like the US, UK, Australia etc when you are downloading torrents is not a good idea. Moreover, the ISP can release the history of all your downloaded files at the demand of a copyright plaintiff, so using a VPN service while browsing torrent websites is a must. In a nutshell, downloading copyrighted files puts you at risk of facing criminal charges that can cause a significant emotional and financial burden on you. Readers of the following should bear in mind that various jurisdictions have pursued legal actions against a website that host BitTorrent trackers, and users that download them on their computers. Whether the publishers of metafiles are violating copyrights by linking the copyrighted content without the authorization of the copyright holder is still controversial. To this day, there is much controversy over the use of trackers besides the fact that BitTorrent metafiles do not store file contents. A VPN will allow you to access sites that might be blocked in your area.īesides the fact that the BitTorrent protocol itself for file sharing is legal, using the protocol to send and receive copyrighted material is not. Some ISPs don’t approve of their users making use of torrent websites so actively block these type of sites. NOTE: If any of the sites in our list don’t work from your location, you may need a VPN to access the website. Quite a few websites listed have survived the test of time, while others are mirrors or copies of defunct ones, and some others are new ones that are gaining more and more attention from internet users.įor starters, let’s go through the tormented history of the BitTorrent protocol from its inception to this day. In our selection, the authenticity of the torrent files listed, along with the safety of downloads, reliability of the listing directory, number of genuine torrents listed and the number of seeders were among the more important selection criteria we based our research on.įollowing a thorough assessment, we compiled a list of the best torrent websites up and running as of June 2020 for your convenience.
