  • Feasibility of Sorted Iterators

    Jump

  • You would have to either mutate the original vector or clone it, yes. If you really want to iterate through an immutable Vec with only constant memory usage, then you probably can't get around O(n^2) runtime, but maybe there is some time-memory-tradeoff where a small memory usage can get some time reduction.

  • Feasibility of Sorted Iterators

    Jump

  • Maybe a heap data structure is what you're looking for. Depending on the usecase you might have to first turn an unsorted Vec into a heap (runtime in O(n), which is still faster than fully sorting it), at that point you can both insert new elements and remove the minimum element within a time in O(log n).

  • Number on or number off which one do you prefer??

    Jump

  • Number only, get out of here with superfluous symbols. I don't need The Status Bar: Illustrated Edition.

  • Mullvad on the Donation Controversy

    Jump

  • I don't disagree with the position of the company as outlined in this statement and their neutral position. But by being a customer of the company I would also be paying the co-founder with his weird views that are definitely not neutral, and that is still worth avoiding. And maybe his individual opinions are actually more representative of the companies values because they aren't filtered through a PR team. As long as they are not the only good VPN provider, I don't want to support this.

  • TIL the country code for Switzerland is CH and is derived from Latin name for Switzerland, Confoederatio Helvetica

    Jump

  • The reason is to avoid favoring any one of the four official languages by deriving the code from a neutral, fifth language.

  • Error Handling in Rust vs. Exceptions in other languages

    Jump

  • There is the map_err method on Result which simplifies this case. But yes, anyhow is still easier if you don't care that much about the error contents.

  • Debian Project Leader Addresses New Age Verification Laws

    Jump

  • Can you verify this? Maybe we should require Debian contributors to prove they are adults. /s

  • (Question) what should I do with this? Any ideas? (Preferably vegetarian suggestions if possible)

    Jump

  • Truffle Pizza can be very good and is relatively common in Italy. I couldn't tell you how to make it, but you can certainly find recipes for it.

  • How many of you are substance free?

    Jump

  • I'm living without alcohol and caffeine (except in tea and chocolate) and really never have the feeling of missing anything. Can recommend.

  • Deleted

    Permanently Deleted

    Jump

  • Nope, never use it. I know how to write code myself.

  • Error handling in bash

    Jump

  • But you can just as well make an exception to allow errors when -e is enabled with something like command || true, or even some warning message.

    I feel like, while it does occur, allowing errors like this is more unusual than stopping the script in an error, so it's good to explicitly mark this case, therefore -e is still a reasonable default in most cases.

  • Europe’s $24 Trillion Breakup With Visa and Mastercard Has Begun

    Jump

  • That's just a different proprietary app though.

  • What additional concepts should I learn before starting to learn rust?

    Jump

  • That's a very good background and should be more than enough to understand the rust book. But if you do eventually want to go more into the theoretical background, I recommend looking towards type theory, specifically Algebraic Data Types (ADT) which Rust uses a lot, and Polymorphism (Generics). But it's certainly not required to write good Rust code.

  • ML-LIB: Machine Learning Library Proposed For The Linux Kernel

    Jump

  • It's wild that one of the problems is that the kernel doesn't use floating point numbers.

    How Big Tech Killed Online Debate

  • Real NASA research papers

    Jump

  • Unfortunately not real, I would have loved to read into some of them.

  • $35

  • CIДАЯETTES

  • What are some cool and obscure data structure you know of?

    Jump

  • Right, which occurs in particular when dealing with graphs, which are basically matrices and usually sparse. Large graphs are what I used this format for, however I also needed edge weights, so the first column was still required for that.

  • What are some cool and obscure data structure you know of?

    Jump

  • The CSR (compressed sparse row) format is a very simple but efficient way of storing sparse matrices, meaning matrices with a large amount of zero entries, which should not all occupy memory. It has three arrays: one holds all non-zero entries in order, read row by row, the next array contains the column indices of each non-zero element (and therefore has the same length as the first array), the third array indices into the first array for the first element of each row, so we can tell where a new row starts.

    On sparse matrices it has optimal memory efficiency and fast lookups, the main downside is that adding or removing elements from the matrix requires shifting all three arrays, so it is mostly useful for immutable data.

  • Debian Gets Its Own PPA-Like System as Debusine Repositories Launch

    Jump

  • In my opinion yes, Debian is the best choice for server machines, especially on the homelab scale.

  • What are some of your most useful or favorite terminal commands?

    Jump

  • How does this even work? I get the redirection part, but how is the command executed in a detached state?
