Ask HN: What are the best engineering blogs with real-world depth?

I’m looking for examples of high-quality engineering blog posts—especially from tech company blogs, that go beyond surface-level explanations.

Specifically interested in posts that: 1. Explain technical concepts clearly and concisely 2. Show real implementation details, trade-offs, and failures 3. Are well-structured and readable 4. Tie engineering decisions back to business or product outcomes

Any standout blogs, posts, or platforms you regularly learn from?

    You might be more interested in books than a blog.

    For example: The Architecture of Open Source Applications

    It's so interesting to me as a Mechanical Engineer and Hardware designer/architect how on HN "Engineering" almost always means "Software engineering" here.
    • throwaway4PP 1 day ago
      It is funny, almost as funny as an entire cadre of people with “engineer” in their title who've never had to draw a free body diagram, learn circuit analysis, understand the basics of thermodynamics, or the mechanics of materials.
      • p2detar 1 day ago
        I hold a CS master degree from an Eastern European university and everything you listed was in our Bachelor degree program. It’s pretty funny because while studying material properties back then I always wondered how and when am I gonna use that. It kind of makes sense now that I think about it - some students preferred branching out to hardware.

        edit: typo

        • throwaway4PP 1 day ago
          That’s great, unfortunately it is quite rare for CS undergrad programs in the US to require the basic engineering and science classes the other engineering/science majors require.

      Hear hear. The word "Technology" has also been redefined to mean computer or phone stuff. As a real (manly) engineer, this pisses me off no end! :-)

      To answer the OP, this Civil engineering blog / video site is really good. I always learn something new, and his enthusiasm is infectious. Well worth giving it a look:

      I would love more blogs on mechanical, hardware, and especially industrial engineering, but the demographics in those areas skew stereo-typically older and also likely less blog-oriented, right?
      • georgeburdell 1 day ago
        Blogs are almost 30 years old at this point, but yes, I do associate a nearly compulsive need to show off one's work in meticulously-crafted blog posts with younger people.

      • wheelinsupial 1 day ago
        Depending on what you're looking for in industrial engineering, there are a lot of blogs on lean manufacturing and the Toyota Production System. INFORMS, may be paywalled, also publishes a lot of pretty interesting articles on applications of operations research to industry.

        In general, though, my very limited experience working in manufacturing was that much of the blog equivalents were covered in things like white papers from hardware manufacturers or articles in trade publications. We always had a bunch of magazines delivered each month and there were usually some interesting articles to review.

      Fair Observation, HN surrounded by mostly Software guys, which directly add nuances of "Engineering" and <Software> Engineering.

      but to specific is much important, imo Engineering means "Solving problem at a scale", irrelevant of the industry.

      • h3half 8 hours ago
        Perhaps. Sometimes the scale is "one" - the amount of engineering that goes into bespoke space missions is very large, and very little of that work is re-used for anything other than direct follow up missions
    • metadope 1 day ago
      I remember feeling sheepish when I was hired to a position titled 'Software Engineer'. To me, those two words together seemed incongruent. Not quite an oxymoron but certainly a puzzlement.

      Maybe, generously, in retrospect, an aspiration?

      I never considered myself an actual engineer; I was (and still am) a self-taught un-credentialed computer programmer. More art than science. They made me take the title and the stock options and the business cards.

      I mostly worked for and with EEs, making software tools for test automation. I was a fanboy hardware wannabee (and still am), got some on me but was never a true engineer. I learned from those who practiced their discipline; it was plain to me the reality of real engineering versus what I was doing.

      I suppose in my travels I have on occasion encountered a true Software Engineer. I suppose there's reason to hope that software development will continue to mature and evolve, and eventually the other engineering disciplines will accept software as a science.

      For me, it will always be a joy to make that hardware work with my twiddly bits. Not engineering, no. But very rewarding work that often resembles engineering.

    • sp4nner 1 day ago
      Agreed, though I understand the YC bias. I'm in biotech and mostly follow HN just to see what the software people are interested in these days.
    • eru 15 hours ago
      Well, engineer without any qualification used to refer only to combat engineers. (The term civil engineering betrays that history.)

      Words change meaning over time and with the audience.

      Strong recommend! Julia's posts are always really engaging and educational.

      She also publishes a number of technical topics as ZINES. I bought her "Oh Shit, Git!" zine and learned a ton of useful info, despite having decades in the industry.Zines are a great way to encourage book-allergic coworkers into learning great material.

    • skywhopper 1 day ago
      Yes! Julia is fantastic at explaining concepts, and creating ways to learn about them. She produces a great series of “zines” summarizing a bunch of technical topics, her blog archives are really fascinating, and she’s created really useful tools like Mess With DNS (https://messwithdns.net) which gives you your own DNS subdomain and the means to update records so you can try things out in an easy, harmless way.

    Encountered one specific example about a month ago here on HackerNews - All about automotive lidar. https://news.ycombinator.com/item?id=46110395

    Blog posts where I find quality really shows are usually about something I know next to nothing about how it works. A badly written article usually either goes really shallow or skips some facts when going into depth and requires catchup elsewhere to actually understand it. The lidar article from Main Street Autonomy goes beyond basics and explained everything from the ground up in such a connected way that it was a real pleasure reading it.

      Corporations commonly describe some of their internal processes and achievements because it builds reputation and that can be important for both sales and recruitment.

    You're probably looking for something that is more focused on specific software decisions/implementations, but https://infrequently.org is the best web development blog out there.

    It's not "technical" so much as it just educates you on how to be a good web developer/run a team. There's zero fluff and considerable detail (footnotes are practically blog posts themselves).

    > https://lessnews.dev

    A while ago I felt this "information fatigue" due to the overwhelming updates from the typical news sources (reddit, twitter, even hn).

    So I built a _slow_ webdev newsfeed aggregator that doesn't overwhelm you of constant updates, so you focus on reading the actual blog contents and enjoy other things.

    • ewoodrich 1 day ago
      I bookmarked to take a closer look later, but I'm a little unclear on the premise, could you explain what you mean by "slow"/how it is filtered/curated?
      • bodash 19 hours ago
        Sure.

        Problem I had with the other newsfeeds is that I get distracted by the constant updates, always refresh the front-page, skipping the actual content and just skimming through headlines and comments.

        So I built this one, set it as my homepage, and because it doesn't update often, I will actually read the content of the links. When I'm done, I move on to other things in life.

        It's curated by matching keywords (focusing on web development) on HN, mostly automated but with few manual adjustments now and then.

    Not corporate, but two of the best individual developer blogs are Eli Bendersky's and Rachel by the Bay. They've both been blogging prolifically for a decade+, Eli with a focus on, broadly, compilers and Rachel on SRE/debugging.

          You seem to be new here, so you probably don't know that:

      Some people act like the use of an LLM immediately invalidates or lowers the value of a piece of content. But the case of a question or simple post, especially by somebody for whom English is second language, using an LLM to rephrase or clean-up some text seems like an innocent and practical use case for LLMs.

      I'm not beating up on OP but I chuckled when I read the question. Literally the only place I see the phrase "no fluff" with any frequency is with Deepseek lol.

    • atoav 1 day ago
      Had the same thought. ChatGPT often tells me things like: "This is the hard truth" or "I am telling it to you as it is (no fluff)" or whatever. Just because my initial prompt contains a line about it not making things up and telling me how things are instead of what would please me to hear. I added a line to specifically tell it to not phrase out these things, but it appears to be surprisingly hard to get rid of those phrases.

    There are no such blogs. Usually companies, or individuals, will write these after they implement some feature into their products. Which makes them inherently little pieces of information scattered all over the internet and there is no one blog that is just about this.
    • nishilpatel 15 hours ago
      That’s true. This kind of writing usually shows up as post-implementation retrospectives, so it’s inherently fragmented.

      I’m trying to surface and study those scattered examples—especially the ones that explain why decisions were made, not just what was built.
