The article discusses the difference between “actually a startup” mode and “a growing, professionalizing company” mode. The author highlights that when there are three layers of management between them and the CEO, the company has transitioned out of startup mode. The author argues that startups require individuals who can do the work and fill in when needed, rather than “professional managers” whose primary skill is managing. They caution against moving to a professionalizing stage too early, as it could lead to the displacement of those who have in-depth knowledge and commitment to the product.

The article argues that the dichotomy between a “founder” and a “manager” is false. It suggests that the difference lies in understanding the intricacies of a business and being able to utilize that understanding to navigate beyond the organization’s hierarchy. The article further emphasizes that leaders who lack a comprehensive understanding of the business and aren’t willing to engage with all aspects of it are less effective compared to those who view the business as more than just a financial tool.

3. Honey, I shrunk {fmt}: bringing binary size to 14k and ditching the C++ runtime
Total comment counts : 10
Summary
The article discusses the {fmt} formatting library, known for its small binary footprint compared to other alternatives. It achieves this through careful application of type erasure, minimizing template bloat. {fmt} offers full runtime type safety and is more efficient than printf. The article explores optimizations to further reduce the binary size, such as disabling locale support and removing special handling for formattable types. The author provides insights into the impact of these changes on the binary size and suggests potential improvements.
Top 1 Comment Summary
The article discusses how the formatting in {fmt} is independent of locale by default, which is different from the default behavior in C++.

4. Einstein’s Other Theory of Everything
Total comment counts : 16
Summary
The article discusses Albert Einstein’s attempt to develop a unified field theory, which combines space, time, energy, and matter. Einstein wanted to explain matter as a deformation of spacetime, similar to how he explained gravity. He tried to find equations that would have solutions corresponding to fundamental particles like electrons but ultimately failed. Einstein’s knowledge of the properties of matter was limited at the time, with only gravity and electromagnetism to work with. He believed that electromagnetism could be described in a similar way to gravity. However, he concluded that his approach did not work because the quantity that could be interpreted as mass could take on any value, while actual particles have specific values. Einstein also explored black holes, but his attempt to use them as a clue for his unified theory was unsuccessful. Overall, Einstein’s unified field theory remained unfinished.

The article suggests that the views of physicist Sabine Hossenfelder are not widely accepted among the majority of physicists. While she is considered a legitimate physicist, she has been criticized for portraying her views as more accepted than they actually are and for ignoring counter-arguments. The article also states that her ideas about topics like the explanatory power of entanglement in relation to processes such as moon orbits around Jupiter are considered outside the realm of regular astrophysics. The author advises readers to proceed with caution when considering Hossenfelder’s perspectives.

This article discusses the functionality and limitations of the Link Preview API. The author praises the tool for its ability to display previews in the default interface of different platforms. However, they note that the behavior of the meta-crawlers may vary across platforms, and the previews may not always match what is seen elsewhere. The author suggests that it would be helpful to report any redirects that occur when following links. They also mention that the target URL should be included in the URL query parameters or fragment. Without specifying data in the URL, the tool is seen as a cute web page feature, but with data controlled by the URL, it becomes a native and shareable web utility. The author updates their thoughts based on a tweet they received.

The article discusses the boiling points of various elements, with beryllium having the lowest boiling point at 2742K and zirconium having the highest boiling point at 4650K. It also mentions that the temperature in a TIG (Tungsten Inert Gas) process can reach temperatures close to 3000K, which is higher than the boiling point of beryllium. This suggests that beryllium vapor was likely produced in the process. The author speculates that the beryllium vapor may not have escaped from the apparatus due to various factors, but warns about potential risks of beryllium condensation. The article also mentions similar issues with silicon refining. Lastly, a table is provided with the melting and boiling points of several elements.

Top 1 Comment Summary
The article discusses the problem with Maproulette, which is the gamification aspect of the platform. Some users prioritize earning imaginary internet points, leading them to edit OpenStreetMap (OSM) in a careless manner. They disregard ground truth, fail to analyze tasks properly, and often make slight mapping errors worldwide. Additionally, the default setting in Maproulette is such that when a task is completed, the system takes users to another task randomly. This further exacerbates the issue, as users may delete tags or make incorrect changes without verifying their accuracy to earn more points.
