Computer Wars, Now & Then
This and the fact that the slew of programs that HP expected developers to produce for the machine failed to materialize, led the firm to announce only seven weeks after the TouchPad’s introduction that it was going to discontinue manufacturing... Users quickly found that the WebOS, or something, made the TouchPad’s speed resemble molasses in January compared to its competitors, mainly the Apple iPad OS and Google’s Android. Although it has since announced one more production run of the TouchPad, this is thought mainly to be for the purposes of clearing out inventory and meeting unmet obligations to large customers.

The company claims that this new release accelerates performance of SPARC T4 and x86-based applications by up to 300 percent as a result of leveraging Oracle's advanced compiler technology. |
Для увеличения эффективности вычислений BASIC был реализован как интерактивный язык, причём это было сделано задолго до того, как режим разделения времени стал стандартом...
Сейчас попробовал потестировать подобный пример на трех языках, у которых переменные описываются в "выделенных" блоках (Паскаль, Ада, Фортран) и для которых у меня под рукой есть компиляторы. Ада (GNAT) и Фортран (GFortran, SunF, Open64, IFC) сделали в точности то, что должно было получиться - области использования переменных были найдены и локализованы, лишние ресурсы не потребовались....
