Total comment counts : 17
Summary
This article provides a list of useful tips and tricks for maximizing the functionality of your browser’s debugger. It assumes a moderate to advanced understanding of developer tools. Some of the tips mentioned include using expressions with side effects in unexpected places, such as logging to the console within breakpoints, creating conditional breakpoints to simulate logpoints in Firefox, using console.log in the watch pane, setting DOM mutation breakpoints, finding the source of unpaired function calls, measuring the execution time of code using console timing API, pausing execution based on specific conditions, creating conditional breakpoints for excluding certain lines from pausing, assigning unique IDs to class instances, using global booleans to control conditional breakpoints, tracing class method calls using Chrome’s monitor command, debugging functions in the console without knowing the source, pausing execution before URL modifications in single-page applications, using object getters with debugger calls to track property reads, copying information directly to the clipboard using console API, using the JS console to diagnose HTML/CSS problems, pausing JS execution to inspect a conditional DOM element, and accessing the DOM and event listeners in the debugger.

2. How to boss without being bossy
Total comment counts : 46
Summary
The article discusses the challenge that leaders face in directing their team members without being perceived as bossy. It emphasizes that most team discussions should involve everyone and not impose a strict hierarchy. The leader’s primary role is to nurture the discussion and help the team reach a solid choice. However, there are times when a command is necessary, and the article explores different ways to give commands using various words and phrases. It suggests that using a straightforward imperative verb can be clear but harsh, while adding “please” can make the command more polite. Other options, such as using the future tense or turning the command into a question, can soften the directive. The article encourages leaders to find a command style that suits their personality, team, and organizational culture to effectively direct their team members.

The author of the article started using a tool in a project to replace a slow editing interface. The tool worked well and allowed for quicker editing and pasting of rows. The author had to write their own component for column validation. They did encounter two issues: the tool didn’t have built-in column resizing (which wasn’t a major problem for the author) and the author wanted to disable the functionality of selecting rows or columns by clicking on the header or gutter. The author wasn’t sure if this was a common enough need to be included in the tool’s library.

They reference a specific website, https://www.infragistics.com/, which likely holds relevance to their point.
5. When NASA Used an RC Tiger II to Drill into Space Shuttle Tires
Total comment counts : 12
Summary
The article discusses how NASA used a remote control tank, specifically a Tamiya remote control Tiger tank, to help test and release pressure from tires on the Space Shuttle. This was necessary because the tires were subjected to tremendous forces during landing and could explode with the force of dynamite. The tank, named the Tire Assault Vehicle (TAV), was custom-made with a drill and camera attached to it and used to approach the damaged Shuttle tires and drill holes in them. The TAV proved to be a successful and cost-effective method for safely handling the dangerous task.

6. Texture Healing for Monospace Fonts
Total comment counts : 25
Summary
Texture Healing is a feature created for the Github Type System series of Monospace fonts. Monospace fonts have certain compromises in their design, such as narrow glyphs like ‘i’ feeling wide and wide glyphs like ’m’ feeling narrow. Texture Healing aims to address these issues by creating alternates for certain glyphs that can give or take space. These alternates shift to the left or right without changing the glyph bounds. The goal is to improve the spacing and density of words without changing the overall word length or monospacing. The feature uses OpenType classes and lookups to determine when to use the alternate glyphs. Texture Healing can be implemented in any modern font editor.
Top 1 Comment Summary
The author is bothered by the fact that the same letter glyph can vary within a word. They give the example of the letter “m” being narrower between the two “i"s in the word “minimum,” which is unsettling to them. They feel the same way about the letters “i” in the word “miniature.” This inconsistency gives the author the sensation of looking through a fish-eye lens or having an incorrect glasses prescription.

8. Hashmaps in Factor are faster than in Zig
Total comment counts : 8
Summary
The author of the article discusses their experience with the Zig programming language and compares its performance to that of the Factor programming language. They encounter a performance issue in Zig’s implementation of HashMap, which causes it to slow down over time. The author identifies the issue as fragmentation in the HashMap due to the use of tombstone buckets. They propose a solution by implementing a rehashing method in HashMap, which significantly improves performance. They share their findings with the Zig community and suggest further improvements. The author also suggests that Factor could benefit from similar enhancements.
