### AI overview

An opinion article argues that nitpicking minor issues in code reviews wastes time. Small problems usually have limited impact, may never cause trouble, and can often be fixed later, so review effort should prioritize major problems, bugs, and features.

### Source excerpt

I once wrote about how I've stopped nit-picking in code reviews, which improved the signal-to-noise ratio and helped everyone get along better. I'm back with a third reason to ditch the practice: nit-picking wastes time. By definition, nitpicks are about minor problems:

### AI overview

The article argues that organizational maps can conceal incoherence when strategy, structure, technology, incentives, goals, ownership, teams, and funding do not align. It contrasts coherent organizations, where context transfers across map layers, with incoherent organizations, where people must repeatedly reorient and translate.

### Source excerpt

If what you are mapping is incoherent, don't fall in love with the map (or your personal ability to navigate with it).

### Source excerpt

There's a family of tabletop games that are based directly on a nontrivial mathematics problem. As a casual and fun way to inaugurate my new blog (migrated from Wordpress to Hugo, after my work on getting better LaTeX mathmode support in Hugo), I thought I'd write a short listicle about them, so that I have a place to add more as I find them, as well as give the shortest canonical description of the associated math problem.

### AI overview

An interview with Skyscanner VP of Engineering Myra Fulton about her path from hospitality studies to software engineering leadership. She discusses lessons from support and mortgage development roles, including the importance of documentation, code quality, testing, and the real-world impact of software defects.

### Source excerpt

Skyscanner VP of Engineering, Myra Fulton She is Skyscanner's most senior female engineer, but Myra Fulton's career as she knows it almost didn't happen -- a last-minute decision to change her university course from hospitality to engineering set her on a completely different path to the one she'd intended. This International Women In Engineering Day, we sat down with Myra to hear her about her journey to the top. Myra, what lead you to engineering originally -- was it always the plan? Engineering was very much not the plan -- I wanted to get into hospitality, and had dreams of running a hotel group. But fate -- in the form of an amazing teacher called Mr Haggerty -- intervened. He convinced me to take up computer science and basically changed the course of my career. He then did the same for a fellow engineer here at Skyscanner, Mhairi McClair several years later! So thank you, Mr Haggerty. The way Mr Haggerty taught computer science brought the subject to life -- I loved how you could solve problems in really interesting ways, and doing that with technology was exciting. It suited my analytical brain, so I decided to switch my uni course from Hospitality Management to Computer Studies. What happened next -- what was your journey to Skyscanner? I graduated with a first class honours spent a year's placement with IBM. After graduating, I got on the grad programme with a bank and spent nine years there. My career started in a number of first and second line support focused roles where I learned the importance of good handover documentation and run-books. I then got the privilege to lead the mortgage development team where I started to learn the other side of software development. It was during my time there that said bank had announced they'd undercharged people for mortgages due to a bug in services. While I wasn't involved in that bug, it really taught me the fragility of software and the importance of the quality of code, of testing and of the impact that can be made on

### AI overview

The article argues that Kotlin Multiplatform is best suited to sharing business logic between Android and iOS while allowing platform-specific UIs. It contrasts this approach with end-to-end frameworks such as Xamarin, Flutter, and React Native, citing ecosystem flexibility and access to existing platform libraries as advantages.

### Source excerpt

Unlike Xamarin, Flutter or React Native, Kotlin Multiplatform does not live within its own ecosystem, which is why it's powerful and flexible dev framework.

### AI overview

This article explains that NP-hardness is a worst-case mathematical property, not a claim that a problem is always difficult for humans or algorithms. Using Super Mario as an example, it shows how game levels can encode boolean logic and why solving the game in full generality would encompass hard computational problems, while ordinary real-world levels may still be solvable efficiently.

### Source excerpt

When NP-hardness pops up on the internet, say because some silly blogger wants to write about video games, it's often tempting to conclude that the problem being proved NP-hard is actually very hard! "Scientists proved Super Mario is NP-hard? I always knew there was a reason I wasn't very good at it!" Sorry, these two are unrelated. NP-hardness means hard in a narrow sense this post should hopefully make clear. After that, we'll explore what "hard" means in a mathematical sense that you can apply beyond NP-hardness to inform your work as a programmer.

### AI overview

This article recounts how Ada Lovelace worked on a mathematics problem related to the Analytical Engine and documented what is described as the first known computer program for calculating Bernoulli numbers. When she became stuck, she went horseback riding and expected the problem to become clearer later.

### AI overview

A proofless introduction to information theory explains noiseless and noisy communication problems, encoding schemes, entropy, and how entropy differs from Kolmogorov complexity.

### Source excerpt

There are two basic problems in information theory that are very easy to explain. Two people, Alice and Bob, want to communicate over a digital channel over some long period of time, and they know the probability that certain messages will be sent ahead of time. For example, English language sentences are more likely than gibberish, and "Hi" is much more likely than "asphyxiation." The problems are: Say communication is very expensive.

### AI overview

A ReactOS developer reports testing SHFileOperation by moving, copying, and deleting folder structures, but could not reproduce the suspected file-writing problem. The article then examines whether to fix SHFileOperation directly or implement it around IFileOperation, including Microsoft's internal approach.

### Source excerpt

Hello again! As I mentioned in the last report, I had been writing tests to find the problems in SHFileOperation. All I knew was that in some situations it would end without fully writing some file, so I wrote tests moving, copying and deleting a folder structure, and comparing the copy with the original. I tried with empty files first, then with files of random sizes, then with really big files, and also with a lot of files of relatively small size.

### AI overview

A tutorial-style reminder of Lagrange multipliers for optimization problems. It reviews gradients, partial derivatives, dot products, and directional change for multivariable functions.

### Source excerpt

For a while I've been meaning to do some more advanced posts on optimization problems of all flavors. One technique that comes up over and over again is Lagrange multipliers, so this post is going to be a leisurely reminder of that technique. I often forget how to do these basic calculus-type things, so it's good practice. We will assume something about the reader's knowledge, but it's a short list: know how to operate with vectors and the dot product, know how to take a partial derivative, and know that in single-variable calculus the local maxima and minima of a differentiable function $ f(x)$ occur when the derivative $ f'(x)$ vanishes.

### AI overview

ReactOS developers locked the forum because of malicious activity and said it would remain locked until the issue was fixed. The development team also warned that disruptive users could be banned.

### Source excerpt

Forum Issues We're currently dealing with some malicious activity on the forum. Some of the developers have decided to lock it until the problem is fixed. Quite frankly, it's disappointing that we need to go this far, but we the development team will ban and kick people who refuse to behave or cause problems for us.
