4. Charging a lithium battery to 80% only?
Total comment counts : 45
Summary
The article discusses the practice of optimizing battery life by charging only up to 80% capacity. The author argues that while this may reduce the amount of energy available in a single charge, it significantly extends the battery’s overall lifespan. They provide a graph showing that charging to 80% instead of 100% can multiply the amount of energy transferred over the battery’s life by a factor of four. The author also mentions that in satellites, batteries are often designed to charge and discharge between a third and two-thirds of their capacity to maximize their lifetime. They conclude by advising users to charge their batteries as often as possible but as little as necessary, typically staying within the range of 30% to 80% capacity.

6. Why did base64 win against uuencode?
Total comment counts : 11
Summary
The article discusses the differences between uuencode and Base64 encoding formats for 8-bit data. It mentions that uuencode was more popular for a time due to its robustness and user-friendliness, but eventually lost to Base64. The main reason for Base64’s popularity is its support by MIME, a binary encoding standard. Uuencode had issues with mail software and gateways, as well as compatibility with different character sets. Base64 is slightly more compact and does not require a character indicating line length. Some reasons why Base64 was disliked include the lack of file name and mode storage, and the difficulty of acquiring a base64 decoder. Base64 solved these problems and was favored for use within MIME. The decline of terminal-mode access and the rise of GUI and web browsers also contributed to uuencode’s decline. Overall, Base64 became the preferred format for encoding 8-bit data.
Top 1 Comment Summary
The article explains that uuencode lost popularity to Base64 because uuencode used spaces in its encoding and Internet protocols at the time often caused spaces to be corrupted. This required manual fixing of corrupted uuencode files. In contrast, Base64 was designed to withstand whitespace corruption and be compatible with non-ASCII character sets. As a result, Base64 became widely used, especially in MIME.
