About jdw64

doogwoo@gmail.com https://www.makonea.com/en-US I am a freelance programmer in Korea, so feel free to contact me if you have any work.

No promises on code quality, of course. Cheap things are cheap for a reason, right?

It's not work-related — feel free to reach out just because you want to get closer

    I've built something similar and I'm using it too. In my case, it just finds function, method, or class connections, and it works surprisingly well. Then I debug visually—it's been…

    I think of this as the kiosk economy. It's like how businesses introduce kiosks even when having a human employee would be more convenient, just for the sake of greater profit. The…

    I want to work at a company like that someday. All I've known are factory equipment call-outs, temporary container offices, bosses threatening to kill me if the equipment stops, an…

    I've also researched languages and written a similar piece[1]. Most successful languages had adoption momentum outside of the language itself. Conversely, there are many interestin…

    Outside the English-speaking world, there's generally been a knowledge gap when it comes to programming. Better resources weren't being shared, and AI helps bridge that gap. You co…

    Concurrent connection count and durable write throughput are different things. And AOF doesn't necessarily mean one fsync per record. The benchmark is taking the worst-case speed o…

    I'm building a language with AI as a personal project. My hobby is tinkering with my homepage [1], and for paid work, I'm handling a project related to autonomous drones [1] https:…

    This is an area where deception is possible. For example, if the metric is background API calls, you can fake that too. What matters is how you define 'active users.' In fact, this…

    The more you force unrealistic expectations of exponential growth, the more founders engage in 'façading.' This feels a lot like multi-level marketing and a game of hot potato—keep…

    It's interesting that our views differ. I think it's because of our different experiences. I believe MSA is the right approach. But this doesn't seem like a debate that can be reso…

    Does Redis become that slow when you enable both AOF and RDB? Sure, there's a write cost, but it doesn't lose its ability to maintain tens of thousands of connections. Redis suppor…

    Is it really the right choice to drop Redis and go back to a disk based relational database just to wrap transactions into a single unit? Redis handles tens of thousands of concurr…

    To me, one of the most agonizing parts of programming is that whenever I think I have discovered something new and write down a good explanation for it, I inevitably find out that …

    After reading your follow-up comment, I realize I may have misunderstood some parts, but I think there is a slight difference in our fundamental perspectives. Still, given your con…

    I resonate with much of what you have pointed out, but I have a different perspective on certain parts. Software consists of various layers, and everyone has their own specific are…

    No, code was always difficult. To be precise, it depends on the domain. The people who could actually write algorithms or core implementations were always a minority. Programmers l…

    I agree with some points, but I also disagree with others. I agree that the 'overall' video game industry is recession resistant. Over the long term, it will continue to grow. But …

    Games fundamentally require a lot of artistry, depend on user device performance, and involve many factors to consider. from engine licensing costs to labor costs. There's this con…

    I agree. The problem is this: most companies using PLCs work in isolated networks with internet disconnected, based on confidentiality. There are many difficulties even with using …
