    If you are going to use RE's, use something like https://regexr.com/ to double check that they're doing what you want. I was suspicious of your 'cols = re.findall(r'\d+ .....', i)' line, and indeed it does miss some columns. You should rethink your column detection, and either not use REs or learn how to use capture groups and \w. There would then be no reason to use yet another RE in your column iterator to extract the numbers which you've already detected.
  • 2023 Day 2 Part A [Java] regex pattern not matching
    1 project | /r/adventofcode | 4 Dec 2023
    First time posting here, let me know if I need to edit post to conform to any rules. My issue is that I'm trying to match regex pattern to separate out the number of cubes drawn and its color but my Matcher object seems to not be returning any matches so it's throwing a no match found exception when I try to call digitMatcher.group(). I have tested my regex pattern on sites like regexr and it seems to pass there but it's not working for some reason here. I use the same type of regex on day one and it work there so I'm not sure where my regex pattern is failing here. I'm talking about specifically in my isGameValid() method where I create a matcher base on a pattern I made above. Through debugging I know that I separated the string color pairing correctly and that my Matcher object has the correct regex pattern, it's just not matching for some reason. Any help would be appreciated. Code below:

  • Ask HN: Anyone looking for contributors for their open source projects
    13 projects | news.ycombinator.com | 21 Mar 2024
    I'd like to make a pitch for Openlibrary.org the free online library from Internet Archive that includes a fulltext search of millions of books.

    I've been volunteering with them on and off for several years and it's always a lovely experience. Their backend is python and frontend mostly from python templates and some Vue for librarian stuff.

    Every Tuesday they have a call on Zoom that everyone is welcome to join to share what they're working on, ask for help, and generally chat a bit. It's a great time.

    Depending on what you're interested in there's a lot to do from helping build import pipelines for more book entries, writing bots to cleanup data, Performance improvements, better documenting public APIs, etc

    I'm currently slowly working on a wikidata integration for their authors page. We also could use some help upgrading to Vue 3, mentors for Google summer of code would be helpful, find of ML projects needing help, moving away from old jQuery libraries, etc.

    They can be quite responsive to PRs too like I blogged about here: https://blog.rayberger.org/idea-to-merged-in-less-than-30-mi...

    For example, here's a small issue that could use some help on the python side: https://github.com/internetarchive/openlibrary/issues/8928

    OpenLibrary does provide search access to full texts. For example: https://openlibrary.org/search/inside?q=%22institutional+thi...

    It is open source and they're always looking for contributors. I think they'd especially welcome help improving search!

  • NaNoWriMo: National Novel Writing Month
    1 project | news.ycombinator.com | 14 Nov 2023
    Right now I'm in the middle of the chicken and the egg problem where we don't have enough authors cataloging their publications and b/c of that obviously readers are not interested in using the site.

    I've gone back and forth with taking Open Libray's [0] catalog as that would at least flesh out our collection of books but then I'd have to deal with verifying authors to accounts so they can access their books. Which sounds like a major headache and also just defeats the concept of building a community.

    Since this is really a weekend project, I'm just going to keep building the tools out to perfection and hope people will trickle in over time.

    Luckily for me I just want to write, so the tools I'm building are exactly what works for my writing goals and I think overtime others will find the same value.

  • YSK: You can access many old and out of print hiking books from the Internet Archive's Open Library
    1 project | /r/vancouverhiking | 24 Oct 2023
    The Internet Archive runs what they call the Open Library, which is a unique concept on the traditional library. You can sign-up with minimal details and digitally check out many scanned books from libraries all over the world. The only caveat is that almost all of the books are older editions - ones that would be impossible to find locally. It's great if you're looking for old routes, a look back in time, details about obscure areas, or just prefer to read a book rather than browse AllTrails. Please do still support local authors whenever you can as guidebooks take hundreds of hours to create and are slowly going extinct.

  • Searching for a pharmacy book
    2 projects | /r/ClinicalPharmacy | 25 Sep 2023
    I want to clarify that I'm a non-US citizen, so accessing physical copies from US libraries or buying it from Amazon might not be feasible for me. To give you some context, my personal research was guided by the wiki section of r/FREEMEDIAHECKYEAH (https://www.reddit.com/r/FREEMEDIAHECKYEAH/wiki/reading/). I've conducted research using various online resources, including the Ebook & Open Source/Access Libraries such as Sci-Hub, Z-Library, Library Genesis, Anna’s Archive, and PDF Drive. Additionally, I've checked Torrent Search Engines like The Pirate Bay and BTDigg. Moreover, I've searched in Internet Archive and its Open Library but again I had no luck. However, I haven't yet explored software-based libraries. Finally I've looked into the Ebay if anyone had the particular book but it looks like both the versions are quite rare, because the book was meant to be only for Pharmarcist and especially for American ones.
