Why this article stands out

Jeff Katz’s guide is useful because it refuses to romanticize speedriding. The sport is easy to describe in a seductive way: skis, a small wing, steep terrain, and the ability to move between sliding and flying. Katz acknowledges that appeal, but he makes the stronger point that speedriding only stays beautiful when pilots treat it as a discipline rather than a shortcut to intensity. The article is built around progression, judgment, and energy management, not bravado.

US judge dismisses Trump defamation suit against Wall Street Journal (r/news)

• Am_Deer: Can we do away with not prosecuting a sitting president already? This guy sues everyone. What about the people? When do we get justice?
• zedkyuu: Wonder when we’ll see the EO about preserving national and presidential pride that makes it illegal to say anything bad about the US government. And since the Trump org is the US government…

Why are parents who barely passed high school thinking they can teach/homeschool their children? (r/NoStupidQuestions)

I think AI has killed my passion for Software Engineering (r/cscareerquestions)

• HelpfulNobody: Right there with ya.
• TheoryOfRelativity12: Pretty sure almost everyone feels the same. Coding is easier but the magic of problem solving kinda vanished.
• djdephcon: I feel like I’m more of a code reviewer than a code writer now.

• norofbfg: The gap between capability and reliability seems bigger than most people admit right now.

Claude is on the same path as ChatGPT. I measured it. (r/artificial)

• __Scenery: Anecdotally I think this is very true. The amount of “take a break, we’re done here” responses I get when we are absolutely not done here is far higher than it used to be
• Effective_Basis1555: Didn’t they hire that ai safety lady from OAI responsible for destroying 4o?
• Miamiconnectionexo: Response length down 40% and welfare redirects up 275% is a damning stat. That’s not users imagining things. Something changed after March 26.

Does any tech company generate a significant portion of code with ‘AI’ (Blind)

• rajek: Coding with AI is exactly as precise as trying to generate a specific image with AI. At some point you get frustrated and just edit the work yourself. Software engineers will not be replaced and Graphic designers will not be replaced.
• grammay: Sundar pichai said 25% code is ai written, but that’s just bullshit because another news followed up that it was auto suggestion. Which is fine for logging. But otherwise is bullshit
• wcran: I don’t really understand honestly. It feels like a scam.

Quick facts

• Difficulty: HARD
• Problem: Regular Expression Matching
• Main tags: String, Dynamic Programming, Recursion

What the problem is really asking

This problem is not asking for a full regex engine.

It asks for one very specific kind of full-string match:

• . matches exactly one arbitrary character
• * means “repeat the immediately previous token zero or more times”
• the whole string must match the whole pattern

That last rule is the detail that makes many first attempts fail. A match is not enough if there are leftover characters in either the text or the pattern.

What the problem is really asking

This problem is a constraint satisfaction problem disguised as a puzzle.

The board is almost complete already. The task is to fill each . with a digit so that three rules are always true:

Quick facts

• Difficulty: MEDIUM
• Problem: Longest Increasing Subsequence
• Main tags: Array, Binary Search, Dynamic Programming

What the problem is really asking

An array of integers is given. The task is to find the length of the longest subsequence whose values are strictly increasing.

The key word is subsequence, not subarray.

• Problem: Combination Sum
• Main tags: Array, Backtracking

What the problem is really asking

The input gives a set of distinct candidate numbers and a target. The task is to return every unique combination of candidates whose sum is exactly the target.

Two details define the real problem:

• Problem: Zigzag Conversion
• Main tags: String

What the problem is really asking

The problem gives a string and a row count, then asks for the string that would appear if the characters were written in a zigzag pattern and read row by row.

What the problem is really asking

There is an m x n grid. A robot starts in the top-left corner and wants to reach the bottom-right corner. The robot can only move right or down.

• Difficulty: MEDIUM
• Problem: Search a 2D Matrix
• Main tags: Array, Binary Search, Matrix

What the problem is really asking

The matrix looks two-dimensional, but the key rule makes it behave like one long sorted array:

• each row is sorted from left to right
• the first value in a row is greater than the last value in the previous row

So the task is not really “search a grid.” It is “search a sorted sequence” while remembering that the sequence happens to be stored in matrix form.
