What is real time?

Image
Perhaps more difficult to meet the stereotype "about computer" concept than real time. And yet, as practice shows, not only the majority of users, but most IT professionals have a very vague idea of what lies behind these very common term. Real time - it is actually a sign that the system place a stringent requirement on the reaction rate (response time) to any external events. The term "real time", by the way, almost never used - talk about real-time systems or, more often about real-time. If the system is operating in real time, does not provide the required response time, then talk about her refusal. Real-time systems tend to interact with processes in the real world (hence the "real" time), which usually do not depend on the actions of the system - on the contrary, by the way, the actions of both time and are dependent on external "stimuli". Events in the outside world can occur spontaneously, and the system operates in real time, should alwa...

Verizon Outage

Image
Is your blackberry phone not working? I heard there was a wide spread outage for BlackBerry users. I can't even call someone. The radio is off, and I can't get on the internet. I heard that the issue was resolved Monday but, not for me. This stinks. I have a blackberry curve. Forget the number. But, my service is verizon. Anyone have a blackberry, is your phone not working? I used to have Verizon, and the internet was fine, pretty fast, and I never had laggy Xbox live. One day we had an internet outage and a month after the internet outage was supposedly resolved, Verizon couldn't get ours running again (2 technicians came!). Anyways, we got fed up and switched to Earthlink. Our Earthlink Setup- we have a modem connected by cable in the basement, and our linksys router we bought connects to that. We connect, but the internet on the computer is seemingly quite a bit slower, Xbox Live is super laggy. We knew the connection would be slower, but not this much slower! Should it ...

The heyday of spy-mania.

Tell me, you will be pleased to know that after you spy on... that is, excuse me, are a tacit observation? Presumably, this is unlikely and that the vast majority of readers against espionage. Meanwhile, there is often a dilemma: what is still more important - privacy or the security provided by surveillance? The dilemma that arose repeatedly throughout the existence of mankind, but the information technology, we can say, brought her to the hitherto unattainable heights. That in itself is, in principle, it is quite understandable: after all, to follow someone else has never been so easy as now. And it is not just about the notorious spying on the actions of users on the Internet: now with the hype around it, many forget about such "childish" ways as cameras, keyloggers and other such things. Last week, the tops of news sites got a news intimately connected with the universal spy mania (although probably correct to say, shpionofobiey). The parents of one of the students from P...
