5. How to grow professional relationships
Total comment counts : 15
Summary
The article discusses the author’s insights into professional relationships through the lens of a model called TJS (The Journey to Synergy) Collaboration Model. Here are the key points:
Background: The author reflects on experiences with exclusivity and gatekeeping in professional circles, leading to the development of the TJS model to evaluate where professional relationships stand on a spectrum.
The TJS Model: This model categorizes professional interactions into seven states:
- Everything is a Competition: Characterized by gatekeeping, zero-sum mentality, and exclusionary behaviors like racism or sexism. In the podcast context, this is shown by guests ghosting or declining invitations after receiving a more prestigious one.
- Coexist: Parties acknowledge each other but maintain minimal interaction due to personal, professional, or value differences. On the podcast, this might mean awareness of the show without any desire to participate.
(The article was cut off before detailing more states, but the spectrum suggests a progression towards more collaborative and inclusive interactions.)
Practical Application: The author uses their podcast as a practical context to illustrate where interactions fall on this spectrum, from outright refusal to participate, to minimal engagement or acknowledgment without further interaction.
Reflections: The model isn’t just about categorizing relationships but also reflects on how these dynamics influence professional growth and collaboration. It highlights the natural evolution or stagnation of relationships based on mutual understanding and respect.
The article underscores the importance of recognizing where one stands in professional relationships and how these dynamics can either foster growth or perpetuate exclusivity.

Summary
Summary of the Article on LiveView 1.0.0 Release:
Chris McCord, the creator of LiveView, announced the release of LiveView 1.0.0, marking six years since its inception. LiveView was designed to allow the development of dynamic, server-rendered applications without the need for JavaScript, aiming to simplify the complexities often associated with full-stack web development:
Motivation: The goal was to bypass the traditional complexities of web development like managing HTTP requests, GraphQL, WebSocket connections, and client-side JavaScript configuration.
Functionality: LiveView enables real-time updates directly from the server, handling all dynamic rendering and updates. This reduces the codebase size and simplifies feature development by focusing on server-side state management.
Performance: LiveView offers high performance with tiny payloads, low latency, and the ability to handle millions of connections per server due to its use of Phoenix Channels.
Development Experience: Developers can focus more on feature development rather than dealing with mundane full-stack issues. Features like real-time logs, hot code upgrades without losing state, and global application scaling are made easier.
Implementation: The initial concept was inspired by React’s model but executed on the server. Early versions involved re-rendering entire templates on state changes, which was inefficient. Over time, improvements were made to only update dynamic parts of the template, enhancing efficiency.
Outcome: LiveView not only simplifies development but also outperforms many Single Page Application (SPA) use-cases, providing a seamless, interactive user experience with minimal overhead.

The article offers coding advice related to memory allocation in C. The author congratulates someone on their work but suggests an improvement in the code snippet from “parser.c”. Specifically, the author recommends applying the principles of DRY (Don’t Repeat Yourself) and not casting the return value of malloc(). The original code unnecessarily specifies the type of the pointer, whereas the suggested version simplifies this by using sizeof *ret, which is more concise and less error-prone.
Top 2 Comment Summary
The article discusses the process of building a compiler named 30cc through a self-compilation method:
Compilation Process: The script
.build.pyis run, which uses an initial, bootstrapped version of the30cccompiler to compile30ccitself. This newly compiled version is then used to compile30ccagain, resulting in a final version of the compiler which is saved as./30cc.Makefile Considerations: A comment questions why this self-compilation isn’t managed by a Makefile, suggesting that the issue might be related to needing different output names for each compilation step, which shouldn’t be a significant problem.
Language Constraints: There’s curiosity about whether the author had to limit their use of C features to ensure the compiler could compile itself, or if the compiler naturally supports all the C features used in its own source code.
Compliments: The comment ends with congratulations and praise for the impressive work on the
30cccompiler.

The article discusses a poem and a quote related to the Soviet Union. The poem reflects a sentiment of disappointment with the outcome despite the sacrifices made, metaphorically represented by broken eggs and an unappetizing omelet. This is juxtaposed with a quote from Panait Istrati, who, after visiting Stalin’s Russia, questioned the benefits or results of the sacrifices made under Soviet rule by asking where the promised “omelette” was, given all the “eggs” (or hardships) that were broken. The author of the article wonders if the poem might be referencing this historical critique of Soviet promises versus reality.
