  • For me, it is easier to learn to use git via CLI instead of a UI. When I first started using git, I learned a few command/flag combinations that I use every day and I barely learned anything else about git after. Everything I don’t do regularly I don’t remember, but have written down in a text file of incantations. It is harder to write down what buttons and what menus I have to click.


  • We have all of our build and CI in make so, theoretically, all the CI system needs to do is run a single command. Then I try to run the command on a CI server, it is missing an OS package (and their package manager version is a major version behind so I need to download a pre-built binary from the project site). Then the tests get kill for using too much memory. Then, after I reduce resource limits, the tests time out…

    I am grateful that we use CircleCI as our SaaS CICD and they let me SSH on to a test container so I can see what is going on.




  • 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.







  • 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.
