![]() ![]() ![]() There is no standard Logo, but UCBLogo has the best facilities for handling lists, files, I/O, and recursion in scripts, and can be used to teach all computer science concepts, as UC Berkeley lecturer Brian Harvey did in his Computer Science Logo Style trilogy. Logo is a multi-paradigm adaptation and dialect of Lisp, a functional programming language. There are substantial differences among the many dialects of Logo, and the situation is confused by the regular appearance of turtle graphics programs that are named Logo. The language was conceived to teach concepts of programming related to Lisp and only later to enable what Papert called " body-syntonic reasoning", where students could understand, predict, and reason about the turtle's motion by imagining what they would do if they were the turtle. ![]() Wally Feurzeig, Seymour Papert, Cynthia SolomonĪgentSheets, NetLogo, Smalltalk, Etoys, Scratch, Microsoft Small Basic, KTurtle, REBOL, BoxerĬlose ▲ Symmetry around a point can be obtained using only a few instructions, allowing users to draw hypotrochoids like the one shown here.Ī general-purpose language, Logo is widely known for its use of turtle graphics, in which commands for movement and drawing produced line or vector graphics, either on screen or with a small robot termed a turtle.

![]() ![]() Yes, EO has been around for decades - starting from the Landsat program of the US in the 1970s, the Copernicus programme of Europe in the 2000s and other institutional EO programmes around the world - and much of the EO data is being used extensively by the scientific community, across the world. No, EO is not a saturated market (In fact, I don’t think the market has been figured out at all, in the commercial sense). ![]() No, EO is just not about pretty pictures whose prints you can order online and hang in your wall. No, EO companies do not magically make millions of $ in revenues right after their satellites are launched (I have worked with some big names in EO and I guess, they would agree). Much of this is true, except for the last part - unless satellites are launched for use in the defence sector or with another anchor customer. ![]() Soon after launch, EO companies usually start making millions of $ in recurring revenues with the data they collect.” Recently, I even heard a space expert* say: “ EO is a saturated, overcrowded market, where mostly everything has been figured out. Finally, there are a few who think the job in Earth observation is done as soon as the satellites are launched and they start collecting data. ” The expert community, on the other hand, (remote sensing, geospatial, artificial intelligence) considers EO as this incredible source of scientific data from different type of sensors in space holding the key to solving a number of global challenges of our time. Some in the space community usually see EO as just another segment in the satellite market to be launched with the ~200 launchers/rockets, in development, while others think of EO as images taken from space that (mostly) look beautiful and can be used in “ solving problems in various industries on Earth. Both those within the industry and those outside the ‘space bubble’ do not pay a lot of attention to this market (although that’s changing a little, with a lot of money being thrown into EO startups lately). I have been writing about Earth observation (EO) - this largely, misunderstood and underreported part of the space industry - for a while now. ![]() ![]() ![]() ![]() But I do know it's fun, and I do know I'm anxious to tell you all about it. I don't understand the connection, and there are times I don't even understand the game itself. It's this sort of humor that we've come to expect from DMA, a developer somehow related to the Grand Theft Auto games. You can almost see the tears drifting down her face, yet you don't care because you're laughing too hard. Suddenly, a rocket crashes out of nowhere and kills one of them. Near the start of Space Station: Silicon Valley for the Nintendo 64, two animals are nearing one another in a romantic interlude filled with hints of forbidden love. In fact, such tasks would be nearly impossible for you, since your form is roughly equivalent to a waffle maker with legs." You don't just bounce merrily up the side of a hill, or ride an ostrich, or put on the magical cape and feather hat. Though this may sound like just another fetch quest, it feels like so much more thanks to intuitive execution. "Rather than trying to find all the cheese nuggets on a mountain, or all the geepeepaboos, you are instead trying to reassemble your ship. Space Station: Silicon Valley (Nintendo 64) review ![]() |
