Boomer, robotul dinozaur

Acum cîțiva ani, într-o povestire sf pe care am scris-o, mă gîndisem la un roboțel de felul ăsta, dar ceva mai mare, mai avansat și în forma unui cîine. Ținînd cont că povestirea se întîmpla cîndva în viitor (nu chiar atît de apropiat, e încă în viitor), mai sînt suficiente ocazii pentru a transforma ideea în realitate. Boomer este realizat de aceeași echipă care l-a creat pe Zoomer, un cățel simpatic și tot robotic.

Technology: Difference between a disc and a disk

Disk and disc have very similar pronounciation, but they are very different: 2 alternative spelling for things that are generally thing and circular geometry. For the most part the words “disc” and “disk” can be used interchangeably to describe these flat, rounded objects. The terms and the objects appear in fields such as computers, media, science, anatomy and automotive mechanics. Some of these fields primarily use one spelling, others use both, depending on the specific object. In many fields the spellings can be used interchangeably, but generally in computer technology the word disk refers to the magnetic storage (hard disks, floppy disks or diskettes) while disc refers to optical storage (compact discs or CDs, digital versatile discs or DVDs).

In computers and media these 2 words refer to storage devices for data, music and videos. You can store all kind of files on them, but the difference in their structure give you different ways to write, organize and read the data from them.

Technology: What to consider when buying a ham radio antenna

If you don’t know it yet, ham radio antenna is dedicated to amateur radio (ham) operators, that radio anthusiasts all over the world that spend countless hours searching between radio waves and talking to other people from different part of their country or continent. They are authorized by their communications or postal authorities to transmit and receive at frequencies from a few hundred kilohertz to microwave and they require solutions that will fit their plans, their needs, and, why not, their dreams.

The right ham radio antenna increases the range of the transmission and it help ensure its clarity. Choosing the right antena involves considering several important factors as the type of your radio equipment, the territory you are living in (it’s not the same thing if you are living between mountains or you are living in the middle of a huge plain) and the price of the antenna itself. One on the most important things that matter, depending about the regulatory enivornment is whether the antenna is going to be visible to everybody or invisible (hidden, low power, camouflaged).

Technology: What to consider when buying a television

For the most decades since the television has been invented it has been changed so greatly no one could ever imagine in the begining: we have LCD television, LED television, plasma television and OLED television, we have from edge-tit to full array televisions, from 120 Hz to 600 Hz, from 2D to 3D televisions.

For many many years people needed tv sets for only one purpose: to get what the mass-media was broadcasting. You already know all about that: news, shows, movies and so on. For now… the first thing you must consider when buying a television is its purpose. What are you going to do with it? Are you only watching the news and movies and all kind of entertaiment shows? Or are you going to use it for doing something else? Something like using it as a computer monitor or playing Nintendo WII or any other type of game consoles? Or do you want to browse the Internet using your TV?

Some asked me not long ago what tehnologies changed the world to make is as we know it now. Even my favourite tehnology is the transistor, the list of them is so long it can take days or weeks to enumerate them. I’ll try mention a few of them, the one that I consider the most important.

Steam engines, 1698

In 1698 the British inventor Thomas Savery patented a steam-powered pump which he described as an “engine to raise water by fire”. Thomas Savery’s very basic engine relied on a theory that had been around for several centuries but never successfully applied: the steam would create a vacuum and pull water upwards through a pipe. The technology was improved later with pistons and cylinders by Thomas Newcomen, a blacksmith, and again by Watt in the mid-18th century.
