            Fedora/RHEL/CentOS uses the following naming convention for all packages that installed shared libraries:

            name - this package contains runtime shared libraries that are needed to run programs that are linked with this library.

            name-devel - the "devel" packages contains header files and the symbolic links that allow you to link with the shared library when developing applications that use this library.

            You need both packages to compile the code that uses the library. The devel package specifies a dependency on the main package, so dnf install name-devel is going to install both packages.

            You should invest a little bit of time to learn how to build your own rpm packages. It's not that complicated. When you build your package rpmbuild will take care of analyzing the resulting binary, discovering which shared libraries it links with, then recording the appropriate dependency in your own rpm package, so installing it will pull in only the main name package.

            Answered 2022-Mar-19 at 22:23

            First, it's good to note the difference between equivalence and equisatisfiability. In general, converting an arbitrary boolean formula (say, something in DNF) to CNF can result in a exponential blow-up in size.

            This blow-up is the issue with your from_dnf approach: whenever you handle another product term, each of the literals in that product demands a new copy of the current cnf clause set (to which it will add itself in every clause). If you have n product terms of size k, the growth is O(k^n).

            In your case n is actually a function of k!. What's kept as a product term is filtered to those satisfying the view constraint, but overall the runtime of your program is roughly in the region of O(k^f(k!)). Even if f grows logarithmically, this is still O(k^(k lg k)) and not quite ideal!

            Because you're asking "is this satisfiable?", you don't need an equivalent formula but merely an equisatisfiable one. This is some new formula that is satisfiable if and only if the original is, but which might not be satisfied by the same assignments.

            For example, (a ∨ b) and (a ∨ c) ∧ (¬b) are each obviously satisfiable, so they are equisatisfiable. But setting b true satisfies the first and falsifies the second, so they are not equivalent. Furthermore the first doesn't even have c as a variable, again making it not equivalent to the second.

            This relaxation is enough to replace this exponential blow-up with a linear-sized translation instead.

            The critical idea is the use of extension variables. These are fresh variables (i.e., not already present in the formula) that allow us to abbreviate expressions, so we don't end up making multiple copies of them in the translation. Since the new variable is not present in the original, we'll no longer have an equivalent formula; but because the variable will be true if and only if the expression is, it will be equisatisfiable.

            If we wanted to use x as an abbreviation of y, we'd state x ≡ y. This is the same as x → y and y → x, which is the same as (¬x ∨ y) ∧ (¬y ∨ x), which is already in CNF.

            Consider the abbreviation for a product term: x ≡ (a ∧ b). This is x → (a ∧ b) and (a ∧ b) → x, which works out to be three clauses: (¬x ∨ a) ∧ (¬x ∨ b) ∧ (¬a ∨ ¬b ∨ x). In general, abbreviating a product term of k literals with x will produce k binary clauses expressing that x implies each of them, and one (k+1)-clause expressing that all together they imply x. This is linear in k.

            To really see why this helps, try converting (a ∧ b ∧ c) ∨ (d ∧ e ∧ f) ∨ (g ∧ h ∧ i) to an equivalent CNF with and without an extension variable for the first product term. Of course, we won't just stop with one term: if we abbreviate each term then the result is precisely a single CNF clause: (x ∨ y ∨ z) where these each abbreviate a single product term. This is a lot smaller!

            This approach can be used to turn any circuit into an equisatisfiable formula, linear in size and in CNF. This is called a Tseitin transformation. Your DNF formula is simply a circuit composed of a bunch of arbitrary fan-in AND gates, all feeding into a single arbitrary fan-in OR gate.

            Best of all, although this formula is not equivalent due to additional variables, we can recover an assignment for the original formula by simply dropping the extension variables. It is sort of a 'best case' equisatisfiable formula, being a strict superset of the original.

            To patch this into your code, I added:

            Reinstall Python with python broken - bad interpreter (Linux Fedora)
            Asked 2022-Mar-18 at 04:53

            As suggested in the comments, it is important to download the exact rpm package that dnf is configured to use. This can be found by rpm -qa python3.

            After finding and downloading this package, install it using the rpm -i command. A successful installation will create the /usr/bin/python_version folder. For me, it was python3.10, so /usr/bin/python3.10.

            When this is done, remove the existing symlink at /usr/bin/python3, and instead link to the newly created python version.

            When does docker update images?
            Asked 2022-Feb-24 at 17:51

            If I have an image like python:latest, when will docker check with the repo to see if the tag now points to a newer image, and download that new image?

            I know it will do it if:

            • The image isn't found on your local machine, and you try to run a container using that image
            • You explicitly run docker pull python:latest

            Are there other times docker will update the image? When the docker daemon restarts? When the system restarts (which is probably the same as the docker daemon restarting)? When docker is updated (from apt/dnf repos)?

            At one point, it looked like we had a case at our company where we didn't pin a particular version of an image (used :latest), and after a system update, docker grabbed a new version of the image, and things broke. Clearly version pinning is important in production, but not the point of the question.

            If the image already exists in the local docker engine, docker will not pull it again unless requested. There are flags to request the image gets pulled again on some commands. Otherwise, if you see the image change, I would look for either a docker pull command being run, or the images getting cleaned (e.g. with a prune command).
