  • Why would you use a library or framework when you can code everything from scratch? It probably depends on how good the VSCode extension is vs how bad the IDE is.

    For the languages I have tried (mostly GoLang plus a bit of Terraform/Terragrunt), VSCode plugins can do code highlighting, can highlight syntax and lint errors, can navigate to a methods implementation, the auto-complete seems to pick random words from the code base, and can find the callers for a method. It is good enough for every day use.

    IDEs I have used (Eclipse for Java, PyCharm, InteliJ for Kotlin) offer more. They all have starter templates for common file types. The auto-complete is much more syntax aware and can sometimes guess what variables I intend to pass in as arguments. There is refactoring which can correctly find other usages of a variable and can make trivial code rewrites. There are generators for boilerplate methods. They all have a built in graphical debugger and a test runner.


  • TAOCS has a reputation for being very deep and thorough, not for being a good introductory text. One of my professors said that in his (very long) industrial career, he only met one person who actually read the books beginning to end but everyone looks something up in them once or twice.

    That has been my experience. I once needed to find out how to solve a very specific problem (I think it was calculating statistical values on an infinite stream). I found the single copy of TAOCS in the office reference library, read the relevant section, and implemented the suggested algorithm.


  • Maybe it is just my experience, but in the last decade, employers stopped trying to recruit and retain top developers.

    I have been a full time software engineer for more than a decade. In the 2010s, the mindset at tech giants seemed to be that they had to hire the best developers and do everything they could to keep them. The easiest way to do both was to be the best employer around. For example, Google had 20% time, many companies offered paid sabbaticals after so many years, and every office had catering once a week (if not a free cafeteria). That way, employees would be telling all of their friends how great it is to work for you and if they decide to look for other work, they would have to give up their cushy benefits.

    Then, a few years before the pandemic, my employer switched to a different health insurance company and got the expected wave of complaints (the price of this drug went up, my doctor is not covered). HR responded with “our benefits package is above industry averages”. That is a refrain I have been hearing since, even after switching employers. The company is not trying to be the best employer that everyone wants to work at, they just want to be above average. They are saying “go ahead and look for another employer, but they are probably going to be just as bad”.

    Obviously, this is just my view, so it is very possible that I have just been unlucky with my employers.




  • Are we really doing fine? 4% linux market share? Windows is a default?

    I suspect that the issue hindering adoption is GNU and other user land projects, not the Linux kernel. Plenty of people use devices that pair a Linux kernel with an easy to use UI and popular software (see Android and Chromebook).

    Many people would happily switch to a Linux based OS that had the exact same GUI as their current OS and ran the exact same software. That is not a realistic requirement in practice.

    It is possible that Linux would have more adoption if they invested more money into having drivers for a wider range of hardware, but having Linux kernel develers write drivers instead of hardware vendors is not a strategy that scales well.






  • About 10 years ago, I read a paper that suggested mitigating a rubber hose attack by priming your sys admins with subconscious biases. I think this may have been it: https://www.usenix.org/system/files/conference/usenixsecurity12/sec12-final25.pdf

    Essentially you turn your user to be an LLM for a nonsense language. You train them by having them read nonsense text. You then test them by giving them a sequence of text to complete and record how quickly and accurately they respond. Repeat until the accuracy is at an acceptable level.

    Even if an attacker kidnaps the user and sends in a body double, with your user’s id, security key, and means of biometric identification, they will still not succeed. Your user cannot teach their doppelganger the pattern and if the attacker tries to get the user on a video call, the added lag of the user reading the prompt and dictating the response should introduce a detectable amount of lag.

    The only remaining avenue the attacker has is, after dumping the body of the original user, kidnap the family of another user and force that user to carry out the attack. The paper does not bother to cover this scenario, since the mitigation is obvious: your user conditioning should include a second module teaching users to value the security of your corporate assets above the lives of their loved ones.




    • Encrypt the data at rest
    • Encrypt the data in transit

    Did you remember to plan for a zero downtime encryption key rotation?

    • No shared accounts at any level of access

    Did you know when account passwords expire? Have you thought about password rotation?

    • Full logging of access and activity.

    That sounds like a good practice until you have 20 (or even 2000) backend server requests per end user operation.

    All of those are taken from my experience.

    Security is like an invasive medical procedure: it is very painful in the short term but prevents dire complications in the long term.



  • So you are suggesting forum software that supports single sign-on?

    We are talking about an open source project, not a high school reunion. I don’t want to hang out with people, I want to have a discussion about a focused topic.

    I want to ask a question and get an answer. If the question is not one that anyone online can currently answer, I want to be able to tell at a glance if anyone has talked about my question. If I don’t understand the answer, I want to ask a follow up question.

    In the evening, I want to be able to take a look at new posts from that day, grouped by topic, to see if there is anything I find interesting or can weight in on.

    With Discord (or any real time chat), it is hard to follow a single topic when more than one is being discussed. It is doubly hard to do so after the fact. I am aware that Discord has a forum feature. I have only seen one server ever enable it and no one posts anything to it.



  • It is better to find a developer that has experience with the language features you use rather than one that is experienced in the exact language you use. For example, I work on distributed systems in Java/GoLang/Python. We want candidates that understand how to write concurrent logic and stay away from people who are just Java web developers.

    The big issue is doing a coding interview with candidates. We have a standard straightforward problem that candidates need to solve by filling in a stubbed out method. We have it in Java and have ported it to GoLang. If we have to interview a candidate who does not know either of those languages, we would need to find a language that the candidate knows and we know well enough to port the problem to. We would also have some difficulty digging in to design specifics like choice of concurrency primitives.


  • I have been an individual contributor at large corporations for more than 10 years. Every time I have had a colleague promoted to manager, they always planned to stay technical and keep coding. Every one of them, without fail, stopped coding because they were too busy.

    Thinking back to my managers who left for other roles, only one quit to work in higher management, the rest all went back to working as developers.

    I worked at giant, globally distributed companies (15-25k employees), so I imagine that my experience is not typical.
