Unison definition4/29/2023 ![]() Semver tells you that B 1 and B2 are incompatible, but not how to solve the issue. If lib A depends on B v2, and lib C depends on B v1, and application D depends on A and C, you cannot load a version of B that satisfies D, A, and C. Semver doesn't help in the case of transitive binary incompatibility. Detecting that 2 things are the same through hashing is nontrivial, can it detect that 1 + x + 1 is the same as x + 2? The ASTs are different Solutions that dynamically discover code dependencies and automatically run tests exist for both procedural and functional languages As others have mentioned, the append-only nature of the language makes bugfixes difficult Their solution for the diamond problem (depending on multiple versions of the same library) is having hard dependencies on exact versions, and including both copies can be at best wasteful, at worst bad (what if v2 fixes a bug that was in the v1 dependency), I think this is a hard problem, and the reason why semver exists Since the language is append only, all edits look like additions in version control You can't view your code without special tools, which means all text editors/version control etc. In contrast, most languages store text files on the disk, and build up a similar AST in memory only you will find it becomes easier with practise and the end result could be a happier and more efficient you.- Storing the AST on the disk in a million files is not necessarily the best use of the filesystem. Solutions – What could I do to improve in these areas?Īlthough self reflection can seem difficult at first, or even selfish or embarrassing, as it does not come naturally.Happiness – Are there things that I am unhappy with or disappointed about? What makes me happy?.Problems – What problems are there at work/home that may affect me? For example, responsibilities or distractions that may impact on study or work.Skills – What skills do I have and what am I good at?.Weaknesses – What are my weaknesses? For example, am I easily distracted? Do I need more practise with a particular skill?.Strengths – What are my strengths? For example, am I well organised? Do I remember things?.Thinking about your own skills can help you identify changes you might need to make. When we learn we can become stuck in a routine that may not be working effectively. You wouldn’t use a recipe a second time around if the dish didn’t work the first time would you? You would either adjust the recipe or find a new and, hopefully, better one. In any role, whether at home or at work, reflection is an important part of learning. It is about questioning, in a positive way, what you do and why you do it and then deciding whether there is a better, or more efficient, way of doing it in the future. ![]() Reflecting helps you to develop your skills and review their effectiveness, rather than just carry on doing things as you have always done them. Reflecting and composing a piece of self reflective writing is becoming an increasingly important element to any form of study or learning. To put it simply ‘reflection’ means to think about something. It is a way of assessing yourself, your ways of working and how you study. Self reflection is like looking into a mirror and describing what you see.
