1. Lessons I learned working at an art gallery
Total comment counts : 29
Summary
The author discusses their decision to resign from a job at an art gallery to pursue writing full-time, reflecting on the lessons learned during their tenure. Initially, the job was taken out of necessity due to relocation to Denmark, language barriers, and financial needs following the birth of their child. Despite the job’s initial unappealing nature—selling coffee with poor pay and conditions—the author saw potential in the gallery’s structure and decided to approach it as a project. They attempted to streamline operations and improve the business model, which initially met with resistance from the gallery’s board.
The key lessons learned include:
Building Trust and Coordination: In an institutional setting, one must not only focus on what is best but also build trust and coordinate with others to ensure everyone is aligned.
Taking Initiative Beyond Job Descriptions: Inspired by Sholto Douglas, the author learned the importance of taking full responsibility for solving problems, even if they fall outside one’s official role, to achieve the desired outcomes.
Understanding Stakeholders: The author engaged with various stakeholders, understanding their values and goals to align personal initiatives with the institution’s mission, thereby gaining support and trust.
The article hints at future reflections on different aspects of their gallery experience, like art-making and working with volunteers, suggesting a rich tapestry of professional and personal growth from this period.

The article criticizes an author’s opinions on what makes a “best artist.” The critique focuses on:
Subjectivity in Evaluation: The author claims to predict the success of exhibitions based on how easy artists are to work with, but this is merely his personal judgment without objective validation. There’s no evidence that others share his views on these exhibitions’ quality.
Misalignment with Historical Greatness: The author’s assertion that great artists are adept at aligning with market incentives is contested. The critic argues that many renowned artists historically did not align well with commercial success vectors, often living in poverty or needing other income sources, suggesting that commercial success isn’t a true measure of artistic greatness.
The article suggests that the original author’s criteria for greatness are flawed as they are based on subjective experience and a narrow definition of success, which might not resonate with broader or historical perspectives on art.

The article argues against the notion that quick email responses are a reliable measure of productivity or efficiency. The author believes that allowing a reasonable response time, such as within a business day, is more practical. They point out that immediate responses can sometimes indicate distraction (like being glued to one’s phone), while delays might be due to legitimate reasons like work commitments or personal events (e.g., a child’s birthday party). The author questions if the expectation for rapid replies could be more applicable or understood within certain professional contexts like the arts, where perhaps short bursts of focus are the norm.

4. 8 months of OCaml after 8 years of Haskell in production (2023)
Total comment counts : 34
Summary
The article compares Haskell and OCaml, two functional programming languages, based on the author’s extensive experience with both in production environments:
Syntax and Expressiveness: Haskell is praised for its elegant syntax, allowing ideas to be expressed with minimal code. OCaml, while also from the ML family, is noted to be less terse but still effective.
Feature Set: Haskell offers a vast array of features which can be both advantageous for problem-solving and overwhelming due to the complexity and choice overload. OCaml, with fewer features, leads to a more straightforward development process.
Productivity and Project Management: The author feels more productive in OCaml due to its simpler ecosystem. Haskell projects can be daunting due to the potential complexity introduced by its advanced features, which can make maintenance and onboarding difficult.
Ecosystem and Libraries: Haskell has a larger ecosystem with more packages and solutions, which, while beneficial, complicates library choice. OCaml’s smaller ecosystem means fewer choices but also fewer complications, with tools like its VSCode plugin working smoothly.
Tooling: Haskell’s tooling is described as an emotional roller coaster - incredibly powerful yet sometimes lacking in usability essentials. OCaml’s tooling, though less comprehensive, is more straightforward and reliable.
Compiler Interaction: The article highlights the importance of compiler messages in functional programming, noting that Haskell’s compiler messages could be more user-friendly.
In summary, while Haskell excels in expressiveness and offers a broad set of tools, its complexity can hinder productivity and project maintainability. OCaml, with its more limited but robust feature set, provides a less overwhelming experience, potentially making it more suitable for practical, straightforward development tasks.

Syntax Preference: Despite acknowledging Haskell’s elegant syntax, the author dislikes ML-type syntaxes, including Haskell’s, suggesting personal taste in programming language syntax does not align with Haskell’s design principles.
Brevity in Coding: The author disagrees with the idea that the joy in programming comes from using the least number of characters possible, suggesting alternatives like APL or Factor if brevity were the goal.
Overall, the article reflects on the author’s negative experiences with Haskell’s ecosystem and syntax, differing from some common praises of the language.
Top 2 Comment Summary
The article discusses the author’s recurring interest in Haskell, a programming language known for its concise expression of concepts through features like point-free style and monads. Despite appreciating Haskell’s ability to enhance his programming approach in other languages, the author finds certain aspects challenging:
Complexity: While he can handle basic Haskell concepts like monads, more complex features like Monad Transformers and the variety of related packages become overwhelming.
Lack of Built-in Data Structures: Haskell requires external packages like
containersfor basic data structures, which contrasts with languages like Python where such functionalities are included by default (“batteries included”).Dependency on Package Managers: For non-trivial programs, one must use package managers like stack or cabal, which is less user-friendly than simpler command-line interactions like those in
ghci.
The author acknowledges that learning Haskell has positively influenced his programming in other languages, promoting a “functional core, imperative shell” approach. However, he does not see himself using Haskell for serious projects, instead opting for daily functional programming needs through tools like jq on the command line.

7. Vintage digicams are an artistic statement
Total comment counts : 43
Summary
The article discusses a trend among young photographers who are turning away from smartphone photography to embrace the unique, often flawed aesthetics of vintage digital cameras from the early 2000s. This “digicam” revival is seen as a reaction to the oversaturation of high-quality smartphone images, with photographers seeking the nostalgic, low-resolution, grainy quality that these old cameras provide. Influencers and celebrities are contributing to this trend, using these cameras publicly and thus fueling its popularity. The appeal lies not only in the retro look but also in the experimental freedom these cameras offer, where imperfections are celebrated. The article also touches on the debate over what constitutes a “digicam,” with some enthusiasts strictly defining it as cameras from the early 2000s, excluding DSLRs and newer models. This movement parallels a previous resurgence in film photography, highlighting a broader nostalgia for analog imperfections in the digital age.

The article recounts the experiences of a participant in Canada’s first digital imaging and technology film program over two decades ago. Here are the key points:
Program Restrictions: The program did not allow analog submissions, but one student continuously shot in super16 for personal projects, which inspired the narrator to experiment with digital grading to mimic the look of analog film.
Classroom Incident: The narrator submitted a digitally shot but analog-styled film, received a top grade, and when challenged by the super16 enthusiast, the teacher upheld the grade without revealing the digital origin, leading to confusion and the other student submitting an analog film for his final project.
Post-Graduation: After graduation, the narrator and some classmates started a digital film company that won three Emmy awards. Despite the digital focus, there was a recurring trend among filmmakers to incorporate analog elements on set, though these attempts were mostly fads and not practically integrated into the final product.
Appreciation for Art: The narrator expresses admiration for those who tried to integrate analog film, appreciating the artistic statement even if it seemed impractical.
Personal Touch: Recently, the narrator bought an old Sony Cyber-shot camera and enjoyed using it to capture moments, indicating a continued personal interest in vintage or analog-style technology despite professional digital work.
The story reflects on the tension and interplay between digital and analog technologies in film, personal artistic expression, and the evolution of technology in the film industry.

10. Y Combinator and Power in Silicon Valley
Total comment counts : 19
Summary
The article discusses a legal battle between startup AdGrok and its former employer, Adchemy, highlighting how competitive strategies like cornered resources and counter-positioning can play out in Silicon Valley. Here’s a summary:
Background: AdGrok, a small startup founded by ex-Adchemy employees, faced a lawsuit from Adchemy shortly after its founders left to start their own company. This legal action was initiated by Adchemy’s CEO, Murthy Nukala, who was unhappy with the founders’ departure.
Legal and Financial Challenges: AdGrok was in a precarious position with limited funds, having just graduated from Y Combinator and attempting to raise external funds. The lawsuit named the founders personally, putting their personal finances at risk.
Y Combinator’s Involvement: The narrative shifts focus to how Y Combinator, the startup accelerator backing AdGrok, maneuvered to protect its investee. AdGrok’s founders managed to secure legal representation from Fenwick & West through a combination of cash and equity, with additional support from Silicon Valley attorney Ted Wang, motivated partly by the perceived injustice of the lawsuit.
Strategic Response: The legal strategy involved not just defending against the lawsuit but also pressuring Adchemy’s vulnerabilities:
- Investors: Adchemy’s board included influential venture capitalists who could potentially remove the CEO.
- Business Partners: Adchemy was struggling financially and relied heavily on a single customer, Accenture, making it susceptible to pressure from business partners.
Power Dynamics in Silicon Valley: The case exemplifies how power operates in Silicon Valley, where informal norms and the backing of influential figures or entities like Y Combinator can significantly influence outcomes in business disputes.
The story underscores the themes of competitive advantage through cornered resources (Y Combinator’s support) and counter-positioning (using Adchemy’s own weaknesses against it), illustrating the broader implications of power and strategy in dealmaking and business conflicts.

The article discusses the transformation of the tech investment landscape in the San Francisco Bay Area during the early 2010s. Initially, it attributes changes to the tech bubble, low interest rates, and the wealth generated from the Google IPO and other startup acquisitions. This led to former founders and early employees becoming investors, with individuals like Chris Sacca raising significant funds to invest larger amounts into startups, reducing their reliance on traditional venture capital (VC) firms.
However, a reader’s comment suggests a different perspective, arguing that the real turning point was not Google’s IPO but Facebook’s IPO. According to the comment, after the lockout period ended for Facebook employees, there was a noticeable surge in wealth, significantly inflating property prices and increasing the visibility of luxury consumption in San Francisco. Additionally, the comment notes that angel investment groups, acting like mini-VC firms, became more prevalent around the time of the Facebook IPO, marking a shift in the Bay Area’s economic and cultural landscape.
