The first spreadsheet, VisiCalc, had helped launch the Apple II as one of the earliest personal computers in business use. With IBM's entry into the market, VisiCalc was slow to respond, and when they did, they launched what was essentially a straight port of their existing system despite the greatly expanded hardware capabilities. Lotus's solution was marketed as a three-in-one integrated solution: it handled spreadsheet calculations, database functionality, and graphical charts, hence the name "1-2-3", though how much database capability the product actually had was debatable, given the sparse memory left over after launching 1-2-3. It quickly overtook VisiCalc, as well as Multiplan and SuperCalc, the two VisiCalc competitors.
SISTEMA WK3 Product Manual
Lotus 1-2-3 was the state-of-the-art spreadsheet and the standard throughout the 1980s and into the early 1990s, part of an unofficial set of three stand-alone office automation products that included dBase and WordPerfect, to build a complete business platform. Lotus Software had their own word processor named Lotus Manuscript, which was to some extent acclaimed in academia, but did not catch the interest of the business, nor the consumer market. With the acceptance of Windows 3.0 in 1990, the market for desktop software grew even more. None of the major spreadsheet developers had seriously considered the graphical user interface (GUI) to supplement their DOS offerings, and so they responded slowly to Microsoft's own GUI-based products Excel and Word. Lotus was surpassed by Microsoft in the early 1990s, and never recovered. IBM purchased Lotus in 1995, and continued to sell Lotus offerings, only officially ending sales in 2013.[2]
Kapor was primarily a marketing guru. His ability to develop his product to appeal to non-technical users was one secret to its rapid success. Unlike many technologists, Kapor relied on focus group feedback to make his user instructions more user-friendly. One example: the instructions that came with the floppy disc read: "Remove the protective cover and insert disc into computer." A few focus group participants tried to rip-off the stiff plastic envelope of disc carrier. Kapor's recognition that techno-speak instructions needed to be translated to normative English was a strong contributor to the product's popularity.
The name "1-2-3" stemmed from the product's integration of three main capabilities: along with its core spreadsheet functionality, 1-2-3 also offered integral charting/graphing and rudimentary database operations.
You really need to try to launch the command manually from the working directory which your python script is operating from. Once you have the command which is actually working, then build up the subprocess command.
Rooftop solar panels can get hot, particularly during scorching summer days. If the panels do get hot or overheat, they can produce less energy as the temperature rises above their optimal energy production range.
How does this work? Colder temperatures enhance solar energy production efficiency, which increases the amount of electricity produced. Electrons are at rest in cooler climates. When the electrons in solar panels are activated by increasing sunlight, a voltage difference is attained that creates an electric current.
