Ορολογία της Ημέρας (T.O.D) – 29/1/2017 [Machine Learning]

Machine learning is an area of computer science and statistical modeling that allows a computer program to predict an outcome or make a decision without being explicitly programmed to do so.

Machine learning, which forms the basis for artificial intelligence (AI), is closely tied to data analytics and data mining programming. Continue reading

Ορολογία της Ημέρας (T.O.D) – 28/1/2017 [Memory Ballooning]

Memory ballooning is a memory management technique that allows a physical host to take advantage of unused memory on its guest virtual machines (VMs).

When a host OS is short on physical memory, the hypervisor polls balloon drivers installed on the guests to request available memory. The guests respond by using page-reclaiming algorithms to determine which pages are available and can be assigned to the balloon drivers. The process of assigning available pages to the driver is known as inflating the balloon. Releasing available pages is known as deflating the balloon. Continue reading

Ορολογία της Ημέρας (T.O.D) – 27/1/2017 [Misfortune Cookie]

Misfortune Cookie is a firmware vulnerability in many older routers.

Once the embedded software running the device is exploited, the attacker can gain administrative privileges and use the device to gather data, steal credentials or upload malicious files to networked devices. Continue reading

Small Plastic Birds protecting Huge Metal Ones > Flappy bird-drone keeps airports safe — TechCrunch

Remember that plane that landed in the Hudson? The whole saga started with a bird strike. Birds at airports can be a terrifying ordeal, so you’d be unsurprised to hear that airports pay a pretty penny to keep the area around an airport clear. Clear Flight Solutions’ Robird is a drone that flaps its wings…

On bots, language & making tech disappear — TechCrunch (βγαίνουν τα σώψυχα αν μιλάς με botakia?)

This year’s new buzzword in computer design circles is without question “bots.” As with anything we build, we give bots names. A name can be a way of expressing trust in an object — or expressing control over it. But giving a bot an identity isn’t always for the best. Calling a bot Siri does…

Ορολογία της Ημέρας (T.O.D) – 12/1/2017 [Fruit of the poisonous tree]

Fruit of the poisonous tree is a legal doctrine according to which any secondary evidence obtained indirectly through illicit means is inadmissible in court.

Examples of such sources include evidence gained through eavesdropping, illegal wiretapping, coercive interrogations, unwarranted searches or improperly conducted arrests. Information obtained from those sources is inadmissible according to the law of exclusion. The fruit of a poisonous tree doctrine is an extension to that law. Continue reading

Ορολογία της Ημέρας (T.O.D) – 11/01/2016 [Greedy Algorithm]

A greedy algorithm is a mathematical process that looks for simple, easy-to-implement solutions to complex, multi-step problems by deciding which next step will provide the most obvious benefit.

Such algorithms are called greedy because while the optimal solution to each smaller instance will provide an immediate output, the algorithm doesn’t consider the larger problem as a whole. Once a decision has been made, it is never reconsidered. Continue reading
