2. If English was written like Chinese (1999)
Total comment counts : 31
Summary
The article discusses two approaches to address the complexities of the English spelling system. The first approach suggests using Chinese characters, known as hanzi, directly. This would involve creating new representations for English words based on the corresponding Chinese syllables. However, this approach would face challenges with pronunciation and spelling for proper names. The second approach suggests creating a new system called yingzi, or English characters. This system would work similarly to hanzi, with one yingzi representing a syllable with a specific meaning. Syllables that rhyme would have variations on a theme, represented by yingzi. The article also mentions the use of pictograms and ideograms to represent English morphemes. The yingzi would serve as the basis for an open-ended set of characters that represent rhyming syllables. Radicals would be used to distinguish different characters within a phonetic group. Overall, the article explores different methods to simplify the English spelling system by drawing inspiration from Chinese characters.

This article describes the reasons why Chinese characters continue to be used in the Chinese language. It explains that tradition and practicality are the main factors behind the use of logographic writing. The article highlights that Chinese is not one unified language, but rather consists of mutually unintelligible dialects. If a phonetic writing system were to be used, it would be difficult to understand materials written in different dialects. However, with a logographic approach, characters can be understood regardless of pronunciation. The article also mentions that Japanese benefits from the use of Chinese characters, as they make sentences shorter, less ambiguous, and easier to understand.

This article discusses the misconceptions about the Chinese language and its characters. The author mentions that while Chinese characters may appear to make more sense in terms of their meaning, it becomes difficult to determine the pronunciation of a new word just by looking at the characters. The article also points out that English faces similar challenges in this aspect. On the other hand, Spanish is considered to be a language where the pronunciation of words is usually consistent with their written form.

The author is curious about the data engineering positions at Nike because they frequently receive messages from third-party recruiters offering low-paying contract jobs in data engineering and machine learning at Nike. The author believes these roles are targeting professionals with experience in the US but offering salaries significantly lower than the market rate. They also mention another commenter’s opinion that these positions might be suitable for a team with inexperienced developers. The author speculates that these roles might even be scams.
Top 2 Comment Summary
The article discusses the challenges of strong typing in data engineering, particularly in type transduction applications. It suggests that while strong typing is useful in some cases and solved by libraries, there are situations where dynamic languages offer more flexibility and simplicity in code. The article argues that type frameworks like pydantic, often imposed by academia, may not be necessary in the data engineering industry. It highlights that Python is chosen for data processing applications not because of its typing capabilities, but for other reasons.

10. “You Are My Friend”: Early Androids and Artificial Speech
Total comment counts : 4
Summary
The article explores the history of androids that were created to simulate human speech in the eighteenth century. It starts with the origin of the term “android” and how it was coined by Gabriel Naudé, a French physician and librarian, to describe talking automaton heads. The article also mentions the story of Albertus Magnus, a thirteenth-century philosopher who supposedly built an artificial man made of bronze. However, Naudé rejected the idea of talking automaton heads due to their lack of necessary parts and instruments for speech. Despite this, Naudé gave the term “android” its new meaning and it became widely used in dictionaries and encyclopedias. The article then introduces the first actual android, a working human-shaped machine that could play a flute, which was displayed in 1738 at the Saint-Germain fair in Paris.
