Development and introduction[ edit ] A prototype of the Macintosh from at the Computer History Museum The original Macintosh featured a radically new graphical user interface. Users interacted with the computer using a metaphorical desktop that included icons of real life items, instead of abstract textual commands.

Recent Activity After a short stop in Fremantle for to re-fuel, re-supply, and change crew, Seabed Constructor, operated by Ocean Infinity, is back searching for the wreckage of MH Under the terms of the contract, Ocean Infinity will only be paid if the wreckage is found. Subsequent swings will also require a stop in Fremantle for servicing.
There remains about 20, sq km of the priority area that is unscanned translucent white. Under ideal conditions, the eight AUVs are capable of scanning about 1, sq km of seabed each day.
However, until Ocean Infinity gains more operational experience, it is difficult to predict what scan rates are realistically achievable.
With the sparse and imprecise evidence we have, it is impossible to assign a high level of certainty to any impact site, as the satellite data and the drift models allow a broad range of possibilities. So, it becomes a numbers game—the more area searched, the higher probability of finding the wreckage.
This probability will vary some depending on how far north the search reaches. Considering that only 5, sq km of that area were scanned in the first swing, and assuming that there are equal probabilities within that total area, the probability of finding the debris field within the primary area would be about 4.
Considering this low percentage, it should come as no surprise that the wreckage has not yet been found, and we are far from the point of re-thinking the search strategy.
Within the area searched so far, there are three warm spots that CSIRO has designated as priorities, based on satellite images of objects that could have been MH debris, and from drift models that estimated the points of impact from the location of these objects.
We think it is possible to identify a most likely location of the aircraft, with unprecedented precision and certainty.
Unfortunately, all three of these locations have now been scanned with negative results. This is not a total surprise: Two other warm spots have been at least partially searched in the first swing. The first is an impact location near More recently, Bobby Ulich proposed a location near We should know soon whether or not these warm spots are completely eliminated.
Another warm spot that should be searched during the current swing is based on a great circle path between waypoints BEDAX and the South Pole.
I first proposed this path in Augustand I still consider it to be among the best possibilities because of the excellent fit of the BTO and BFO data, and because of the simplicity of navigating in the direction of true south. As shown in the figure above, there are warm spots that reach as far north as 27S latitude that are based on certain navigational inputs.Valokuvaussivusto: vilkas keskustelufoorumi ja uutissivu, jossa joka päivä valokuvaukseen ja valokuvausvälineisiin liittyviä tuoreita uutisia.
Naming. The Macintosh project began in when Jef Raskin, an Apple employee, envisioned an easy-to-use, low-cost computer for the average barnweddingvt.com wanted to name the computer after his favorite type of apple, the McIntosh, but the spelling was changed to "Macintosh" for legal reasons as the original was the same spelling as that used by McIntosh Laboratory, Inc., the audio equipment.
