  • Are solarpunk values part of your thinking process … which company you will be working at?

    I do not  think necessarily about solarpunk, but it ends up being related to solarpunk. When you build software with the intention of it being used for a long time and for many contexts, you make it more sustainable, better against aging.

    And, maybe in a broader sense, is hoping to work on projects aligned with solarpunk values realistic?

    It is realistic and it should be done. Values are a guideline to follow when you need to make a decision. Values of sustainability, justice, hope will certainly guide you to build something that will help more people and have a positive impact in the world.

    I work for a company that mainly does PoC projects with low TRL. This gives me the opportunity to choose the technologies that align with solarpunk: open-source libraries and standards, products that can be self-hosted and scale as needed.

    Moreover, my team and department avoid using big tech products: Mattermost for comms, Nextcloud for storage and docs. Non-developers use Windows for" compatibility" reasons, otherwise, we use Linux.

    Additionally, the company makes products that will be used in renewables and similar sectors, which makes it super solarpunk.



  • I agree that LLM are made to be more exploratory, this is good as it allows them to experiment with more different topic, as opposed to always saying the same. However, I do not agree it is a feature for code generation, as you would need it to follow strict ruleset (code syntax, specification, tests). Whatever errors it generates and people accept are little mistakes in the threshold of acceptance for the person and a tradeoff for the cost of fixing the problem. In some contexts we see people focusing almost only on short term which leads to a lot of errors being allowed.

    Moreover, you cannot say compilers are deterministic. There are situations where they are not (at least for the user).

    GCC’s unwarranted behaviour

    In order to keep the code as small as possible I was compiling the code with -Os. Everything was working fine until I started to remove some printfs and started to get some crashes. Moving function calls around also seemed to randomly fix the problem, this was an indication that somehow memory/stack corruption was happening. After a lot of testing, I figured out that if -O2/-O3/-Os were used then the problem would appear. The issue was caused by Interprocedural analysis or IPA. One of its functions is to determine whether registers are polluted across function calls and if not then re-use them.


  • a relative time formatting library that contains no code

    The library is two text files (code) that are processed by an LLM (interpreter) to generate code of another type. This is not that new in terms of workflow.

    I think what makes this the worst is the fact that the author admits that you can’t be sure the library will work until you generate the code and test it. Even then you cannot guarantee the security of the generated code and as you do not understand the code you also cannot give support or patch it.

    When Performance Matters

    If performance of a datetime processor is not relevant, what is? The author mentions they would like a browser implementation to be fast, documentable, fixable. However, operative systems, browsers, and other complex systems are made of little utilities like this that have very well documented functionalities and side effects.

    But the above isn’t fully baked. Our models will get better, our agents more capable.

    The whole assumption is that instead of creating a good stable base that anyone can use we should be just shtting out code until it works.

    Eventually the hardware will be good enough to support a shitty bloated browser so we don’t need to optimize it.

    Eventually people will harden their PC enough so we shouldn’t care about security.
