The article states that a lot of core packaging development is happening in “uv”. UV is used as the underlying technology in Rye, and as improvements are made to UV, Rye also improves. For example, “universal” resolution has been added to UV, allowing for the generation of a locked requirements.txt file that works on all platforms and operating systems, not just the system being used. Rye also supports this feature in its latest release.

The article discusses the author’s concerns about Rye, a tool that encourages the use of non-standard Python builds. Rye argues that the official Python builds from python.org are inadequate and recommends using the indygreg standalone builds instead. The author disagrees, stating that they have never encountered any issues with the official Python builds obtained from python.org or their distribution’s package manager. They also question the need for using non-standard builds and express hesitation towards Rye’s approach compared to alternatives that utilize the existing Python installation on the operating system.
2. The zombie misconception of theoretical computer science
Total comment counts : 25
Summary
The article discusses the misconception of applying concepts of computability to individual integers or specific yes-or-no questions. The author emphasizes that computability applies to functions or infinite sequences, not individual integers. Concepts like NP-hardness and P versus NP are explained in relation to computability. The author suggests that the misunderstanding arises from a misapplication of concepts designed for infinite sequences and functions. The article concludes by asking readers for ideas on how to address and correct this misconception in theoretical computer science.

The article discusses the concept of computability and how it involves infinity. It explains that there is no algorithm that can compute the Kolmogorov complexity of a string for all possible strings. However, there is an algorithm that can compute the Kolmogorov complexity for strings with a length less than a certain value. This is achieved by creating a Turing machine with a lookup table. The article argues that while this may seem like cheating, it is still a valid algorithm. It concludes by stating that computability becomes more interesting when dealing with an infinite number of things.

The article discusses the concept of constructive mathematics and its alignment with people’s intuitions. It provides an example related to the P=NP problem, stating that there is no proof yet that there exists a program that constructively prints out the answer to the problem. The article also discusses Mark Braverman’s work on computable Julia sets, where he develops 5 machines that draw different sets based on the desired parameter. It explains that in constructive mathematics, the notion of a compact set corresponds to being a computable set for computable Julia sets. The article mentions that it is not constructively provable that every quadratic Julia set is compact, and instead, the complex plane is divided into multiple regions where the corresponding Julia sets are proven to be compact within each region. It also discusses similar results in classical mathematics that don’t hold constructively. The article concludes by stating that constructive mathematics provides a clearer understanding of what additional information is needed to compute a quadratic Julia set.

The author, who previously worked at Google, provides some insight into the development and usage of Google’s internal videoconferencing platform, GVC, and its transition to Hangouts. GVC was initially built using expensive Cisco Tandberg units, but the company wanted a more cost-effective solution. Hangouts eventually replaced the Tandbergs and saved the company a significant amount of money. The author suggests that the mentioned APIs and domain restrictions in the article may be related to monitoring embedded Chrome for GVC, but is not entirely sure.
Top 2 Comment Summary
The article discusses a module called “hangout_services” which appears to be a tool to make developing Google Hangouts easier by providing telemetry data to the team. Hangouts was one of the first apps to enable video calling in web browsers using WebRTC. The module exposes information like CPU/GPU/RAM usage and hardware details to the app, which it wouldn’t typically have access to. The author speculates that Google may delete the module in response to a Twitter thread. They also mention that Hangouts has been considered a dead product for a while, and if it is still being used in their server-side code, it could be removed since the Chrome team likely monitors WebRTC performance in a more comprehensive manner now.

6. Making my own wedding rings
Total comment counts : 29
Summary
The author of the article wanted to make their own rings for their upcoming wedding. They initially attempted to use lost PLA casting to create the rings using a 3D printed mold, but encountered difficulties and defects in the finished product. They learned that molten silver reacts with oxygen and forms bubbles, and that pure metals have a harder time filling in details in the mold. They decided to make an alloy of 90% silver and 10% gold, and constructed a vacuum base for the flask to remove oxygen and improve the casting process. They made multiple attempts, replacing rubber with silicone rubber for better sealing, but still encountered some defects in the finished rings. Ultimately, the author preferred the look of silver over gold and decided to continue using silver for the rings.

9. Linksys Velop routers send Wi-Fi passwords in plaintext to US servers
Total comment counts : 30
Summary
Belgian consumer organization Testaankoop has discovered that certain Linksys routers are sending Wi-Fi login details to Amazon servers in plaintext. This vulnerability affects the Linksys Velop Pro 6E and Velop Pro 7 mesh routers, allowing for potential man-in-the-middle attacks. Despite alerting Linksys about the issue, no effective measures have been taken. Testaankoop suspects the security flaw may be due to third-party software used in the Linksys firmware, but notes that this does not excuse the vulnerability. The consumer organization advises users to change their Wi-Fi network name and password via the web interface, rather than the app, to prevent transmission in readable text. Testaankoop strongly advises against purchasing the affected routers due to the risk of network intrusion and data loss. Linksys has not responded to the ongoing issue.

Top 1 Comment Summary
The author of this article raises the question of the value of web analytics for individuals, specifically in the context of running a SaaS business. The author mentions that they stopped using Google Analytics due to concerns about tracking and because they didn’t see the value of the data it provided. They note that in the past, they could use the “Referer” header to determine where people came from and what they searched for, but that is no longer possible. The author argues that page visits are a vanity metric and that the only metrics that truly matter for a SaaS business are signups and monthly recurring revenue (MRR). They compare measuring a SaaS business based on page views to measuring the performance of a Walmart store by counting cars on a nearby freeway, suggesting that while the numbers may be somewhat related, they don’t provide meaningful insights. The author concludes by stating that they have intentionally avoided using third-party JavaScript on their website and that even if they were to use analytics, they still question their relevance unless running an ad-driven site where page views are the primary concern.
