From ARPAnet to Facebook: The Story of Cyberspace

Hello everyone I am going to talk about two technologies today, where (spoiler alert!! ) one is still in use, and another is forgotten. Please check the used sources on the bottom. I was shocked, when I realized that the used processors for the spacecrafts. I would and I am sure everybody’d think they have the newest, strongest hardware, however it is not the truth. “Many of the processors powering essential spacecraft functions now date back to the 1990”s -Joe McKendrick.[1]
When a spacecraft system is being produced, it has to pass a bunch of tests and different preparations before the release. It can take up YEARS and processing powers on the market can be doubled until tests are done. It is the reason, these spacecraft systems can be safer, but outdated. So basically they concentrate for the reliability, imagine what would happen in space if a processor goes wrong… Let me show you a few interesting example: The “Mars Explorer”; curiosity uses a processor called Dual BAE RAD750, which was passed every test in 2001 and it was launched in 2011. Morpheus, was a test craft, which used the same and was launched in 2012, but got a failure and exploded -lesson need to test more. Most interesting fact was that, the International Space Station’s main computer uses an Intel 386i, which was produced back in 1985 and is outdated since 2007. In my point of view, it is promising, that these processors can still function in our decade, because it means manufacturers made a really good job in a point of view. Read more examples from the sources.
While the first technology is still in use and I promised I will give you an example which is forgotten, this technology is still available, however I am sure no one used it for a while except my grand mom she really likes it. When we were children, We dreamed about getting internet on TV, on that time I am quite sure we did not know about “Teletext”. It is service for televisions where you could get news, subtitles and tv program guide. It is kind of internet built into the television but much smaller and design poorer. I previously said we wanted internet on our TV but if we think a little the opposite happed because right now we are watching TV(stream) on our PCs. Afterall, Smart TV’s came which is a computer if we think in it, but that was not a big deal as watching TV on phone.
Enough about the spiritual aspect, the first Teletext service was in 1974 (!) by BBC and they provided subtitles for hearing impaired people. Later on, Internet just became more popular and available for everyone, so Teletext’s popularity dropped and BBC stopped it in 2009. There are channels that still provide this service, but when was the last time you used it? I, personally can’t remember.

Hello again, I am going to talk about the development of computers basically from ENIAC to IPad. Where to start if not at the beginning.  The first question is what is computing when someone counts computing. When the first humans started to count with their fingers in 2700-3000 BC, I would not say that it was computing. I think it starts when it is connected with electricity. To give respect to others I will introduce those machines that were used for computing without any transistors or even without any other power supply than a human. Antikythera mechanism used in 100 BC it was used for astronomical computing In grammar school I had to learn to calculate on  slide rules. I hated that I felt useless to use such a thing when calculators exist. Let's move on to real computers.. I am sure everybody has heard about Alan Turing. Actually there is a quite good movie about his life, The Theory of Everything. Basically he is the father of AI. He invented the procedure with the help of wh

  Hello everyone it is me again and today I am going to talk about the relation of IT and ethics, more particularly about ethical egoism. I would like to start with an example so Jack believes that Jill should promote her own interest in accordance with ethical egoism. Jack might believe this, but he isn't going to tell Jill. He looks to his own interest first. This means that whatever we do for our benefit it is ethical to do so and it is not considered unethical to not act against our interest. Let's move to the IT field. How does this example connect to IT? We need to consider a situation, this can be a variation of things from a job and its compensation to competing for a position or a pay raise. For instance a freelancer make their own set of rules and can determine the amount of compensation they want in return. Most of the time it is considered rude but they are right in a way. They are a one-man team, doing a lot of hard tasks on a very high level and please be honest w

  Hello again, it me and the following Sunday blog is going to be about bad ergonomics examples mostly from console playing. I have been playing on console since first class so I have pretty much experience. There are two constructions that I think we need to talk about. At the beginning of this market vendors tried to show everything they had. It led to the same very bad design controller or the idea preceded its age. I cannot remember which birthday of mine was that when I got a very special present it was a controller to my Playstation. Its name is Jogoc. It has a very weird design because it has a steering wheel in the middle of the device. Its purpose was to drive more precisely in the racing games than the traditional controller. For obvious reasons it did not live up to expectations. Let’s move on to the next example which is called Soul controller. It was designed for samurai games. I would try that again with the ghost of tushima for sure, of course with some updated gyroscope
