The article describes how the author used Norvig’s lisp2.py to create a low code user interface (UI). They made modifications to the interpreter to accept JSON flavored lisp, replacing parentheses with brackets. This made it easy to build a react front end that manipulates JSON. The author explains that they chose lisp because it provided a serialization format for operations from the front end and a way to interpret them, without having to create their own language.

This article discusses the availability and user-friendliness of an app that is compatible with most major platforms, particularly praising its iOS version. However, it also warns of several bugs that users should be cautious of. For instance, on Windows, running the app with the window visible may prevent the system from sleeping. On Linux, the same issue occurs even if the window is not showing, causing high CPU consumption and constant refreshes. Additionally, on Windows, the app may still show the window even if the “startup minimized” option is checked.

The article describes a web-based service for peer-to-peer file sharing. The service has file size restrictions imposed by browsers, but it utilizes a signalling server to connect clients. Once the clients are connected, file data is only sent over a peer-to-peer connection. However, due to the lack of a fallback TURN server, some network configurations may not be able to establish P2P connectivity. The article emphasizes the trade-off between privacy and the limitations of the service.

The author of the article recalls their involvement in the development of iPHUC, a jailbreak tool. They credit a person named “nightwatch” for spearheading the initial jailbreak and coining the term. Nightwatch was also said to have worked on exploits for unlocking the PSP. The author mentions that Nightwatch possibly lived and worked in South America at a university, but beyond that, they don’t have much information. The author describes the experience as enjoyable and educational. However, they also express frustration with George Hotz, who endangered the welfare of people who had provided documentation in Japanese. This incident led to the dev team eventually ceasing work on the project.
4. Perf Is Not Enough
Total comment counts : 20
Summary
The article discusses the importance of performance in the database industry and the limitations of using performance as the sole metric for choosing a database. The author provides an example of a benchmark comparing cloud data warehouses, where the fastest system according to the benchmark did not align with customer preferences. The author suggests that there are other factors, such as ease of use and integration with workflows, that should be considered when selecting a database. Additionally, the author highlights the impact of factors outside of the database server, such as JDBC drivers, on overall performance. Ultimately, the article argues for a more holistic approach to evaluating and selecting databases.
Top 1 Comment Summary
The article discusses a situation where a company realized that bugs in their JDBC driver were causing performance issues for customers. Despite spending a lot of time optimizing query times, they later discovered that the connectors most users used were adding significant latency. It is frustrating to see that the company was unaware of this problem and did not use their own JDBC drivers.
Top 2 Comment Summary
The article highlights the flaws in Google’s open source strategy. It mentions that Google has built a great internal database called JDBC, but when they subcontracted the development of an adapter layer for external use, it turned out to be subpar. This resulted in the wider world using a poor-quality database, while Google itself continued to benefit from their well-engineered core system. The author suggests that Google seems unaware of this issue internally, and external users are unlikely to realize it. Overall, the article portrays Google’s open source strategy as producing unnecessary subpar solutions.

The author recalls how reading a specific book on computer science 20 years ago sparked their interest and passion for the subject. When they met the author of the book, Dan Jurafsky, 10 years later, they expressed gratitude for the impact it had on their life.
Top 2 Comment Summary
The author suggests that as an application programmer, knowing how to create an LLM prompt and make an API call to platforms like OpenAI, Mistral, Claude 3, or together.ai may render the need for reading the entire book unnecessary. They believe that many project specifications involving NLP or named entity extraction could be handled by a smaller LLM model, potentially even a size smaller than 7b, and with more reliability. The author questions whether this assumption would have held true three years ago and seeks clarification from machine learning engineers.

The article discusses the author’s fear of Alzheimer’s disease and how witnessing family members go through it brings back nightmares. The decline in memory, reasoning capabilities, and character is described as losing oneself. The author ponders whether it is better or worse when the person affected is no longer aware of their decline. The article suggests two books, “Rainbows End” by V. Vinge and “Choosing to Die” by Terry Pratchett, that explore the possibility of finding a cure for Alzheimer’s or choosing to end one’s life on their own terms.
Top 2 Comment Summary
The author of the article expresses their reluctance to know how intelligent they are compared to others, as they believe it could have negative consequences regardless of the outcome. They fear feeling limited if their intelligence is below average and experiencing added pressure and potentially becoming arrogant if it is above average. The author acknowledges that this perspective may not apply to everyone, but personally, they are content with where they currently stand. In regards to the story being discussed, the author appreciates the use of grammar and spelling as a simple yet effective way to depict the protagonist’s progress, apart from the actual content of the story.
7. Building an Open Source Decentralized E-Book Search Engine
Total comment counts : 14
Summary
The article discusses an ebook search website called Liber3, which uses ENS domain names and runs on ENS and IPFS. The author analyzed their network requests and found that they use Glitter, a decentralized database service. However, since Liber3 hasn’t made their source code available, the author decided to implement an open-source community version using Glitter’s documentation and open datasets. They provide four steps to build an e-book search engine using Glitter SDK and display search results on the front-end interface. The article concludes by suggesting that the compiled version of the website can be published on the IPFS network to create a decentralized ebook search engine accessible via any IPFS gateway. The source code for this community version is available in a repository.

8. gh-116167: Allow disabling the GIL
Total comment counts : 17
Summary
The article discusses the implementation of a new feature in Python that allows for the Global Interpreter Lock (GIL) to be disabled. The article mentions the use of the PYTHON_GIL environment variable and the -X gil option to disable the GIL. It also describes how GIL-related data structures are initialized and how the flag is set to enable or disable the GIL. The article mentions that basic threaded programs work fine without the GIL, but running the full test suite crashes quickly. The article also mentions the scheduling of new builds with the buildbot fleet and the addition of test cases. Finally, there are comments from various users, including approvals from different contributors and mentions of the excitement and concerns regarding the new feature.
Top 1 Comment Summary
The writer wants to understand why the biased reference counting approach described in the mentioned source has a single thread affinity requiring atomic increments/decrements when accessed from a different thread. They have observed that other implementations, such as various Rust crates, only increment atomically when moving to a new thread and then perform non-atomic increments/decrements until 0 is reached, at which point an atomic decrement is done. They speculate that the reason for the difference might be because the biased reference counting approach is being retrofitted into an existing system where a single PyObject is used and cannot be exchanged to point to a new thread-local object.
