Source: 1-bit Hokusai’s ”The Great Wave” – Hypertalking

Summary
An artist started a project called “36 Views of Mount Fuji” 5 years ago. The aim of the project is to recreate every woodcut print from the series on an early black and white Macintosh. The artist loves to recreate old Macintosh computers art, and use Aldus SuperPaint 3.0, the software which he used when he was a child.

Fact

🎨 The artist started the project for the pleasure of experiencing the “flow state” and nostalgia-driven reasons.

🖼️ The aim is to recreate Hokusai’s 36 views of Mt. Fuji on an early black and white Macintosh.

🤖 The artist uses contemporary hardware and software, including Aldus SuperPaint 3.0, System 7, and classic Macintosh computers.

📏 The images had to be the original Macintosh screen resolution of 512 x 342 pixels.

🌊 The first image the artist recreated was “The Great Wave off Kanagawa.”

Source: Are sockets the wave of the future?

Summary
The basic design choice between sockets and streams is not a big issue. However, the real issue is that streams don’t fit the normal Unix view of I/O since you can’t do read and write on a stream in SunOS 4.1. It seems clear that you can get streams/sockets compatibility by doing everything with subroutines and supplying streams and sockets versions for everything.

Fact
💻 Using `read` and `write` on a stream may cause performance penalty as the stream doesn’t fit the normal Unix view of I/O.
💻 To get streams/sockets compatibility, do everything with subroutines and supply streams and sockets version for everything.
💻 Sockets make network I/O look a lot more like normal file I/O than streams do.

Source: Despite hopes, vitamin K2 supplements fail to slow calcium buildup in heart valve

Summary
Progressive narrowing of the aortic heart valve of older men due to aortic stenosis could not be slowed by vitamin K2 supplements, according to a recent clinical trial. The research found the supplements were ineffective in slowing the progress of calcium deposits on the aortic valves of older men in helping the condition, a common but severe condition with no current effective treatments.

Fact

🫀 Aortic stenosis affects approximately 2% to 5% of people older than 65, and it is expected that the number will more than double in the United States and Europe by 2050.

🫀 Symptoms may include chest pain, fluttering heartbeat,s trouble breathing, lightheadedness, fatigue, swollen ankles or feet, and difficulty sleeping.

🫀 Aortic stenosis can progress and lead to heart failure and death if not properly treated.

🫀 There are no current treatments for aortic stenosis when detected early, and in later stages, it is treated by replacing the heart valve.

Source: OpenAI’s ChatGPT Powered by Human Contractors Paid $15 Per Hour

Summary
OpenAI is paying $15 per hour to labelling data moderators for their contribution to ChatGPT. The moderator’s work is to tag image & textual dataset to help machines learn in-depth through automation. However, despite their contribution, mod’s receive no benefits or even minimum wages in some states.

Fact
💻 OpenAI pays $15 per hour for data labelling moderators, compared to $2 per hour paid to African moderators previously.
💼 Data labelling or tagging helps automated systems to understand specific items in a dataset.
👥 The human contribution of data labelling is essential for the training of machine learning models.
