  • Algorithms and Data Structures in Scala;
    3 projects | /r/scala | 29 Jan 2022
    is there a great resource, book or library‍ on classic Algorithms and Data Structures in Scala, e.g. similar in scope and quality to Sedgewick Algorithms in Java https://algs4.cs.princeton.edu/home/ I found a very helpful section on algorithms implementation in /u/lihaoyi superb Hand-On Scala Programming book , but unfortunately it's only a few pages (p.107-121). And most other books provide algorithms just an illustration for some neat language feature. The thing is, to get a job as Scala developer these days (in competitive firms) one needs to be a competitive programmer, master of Leetcode, and Scala doesn't seem to have strong ecosystem in that regard as Java, Python or C++. Edit: in DIY spirit and as a learning exercise i'm thinking of translating Sedgewick Algorithms from Java to idiomatic functional Scala, if anyone wants to join this effort or aware of similar ones please let me know Edit 2 (in regards to comments on 'reinventing the wheel' below): if Scala is so great as a language and functional programming flagship, where are all the libraries of functionally implemented algorithms replacing conventional CLRS style imperative/mutable implementations?

    handsonscala is a great read for programming in general using scala. Especially if you're the practical kind of learner.
  • Scala at Scale at Databricks
    4 projects | news.ycombinator.com | 9 Dec 2021
    I will toot the author's horn for him. He has a great series of Scala posts on his blog [1] and his book Hands-On Scala Programming [2] is a great introduction to building real applications with Scala so that any experienced developer can understand and extend them.

    I work at a small company that has been using Scala for 7 years. Some of the prior employees clearly enjoyed playing with advanced language features and writing libraries for the most general possible case even when that made it hard to understand how they were used for the 2 actual cases we needed to address in our application code. Akka, Cats, and Shapeless were all over the place.

    Those earlier employees have churned off to other places and I have successively simplified the code they wrote that is still useful, while encouraging the use of no more language power than necessary in new development. Hands-On Scala Programming is the book I give new hires as a language introduction that shows the sort of style to be preferred. It's much more like super-powered Python than like Haskell.

    I have written C, JavaScript, Python, and Scala for money. When I started on Scala I had never written Java nor used any JVM language. I have come to really appreciate the rich ecosystem of JVM libraries, the instrumentation and profiling tools I get, and many aspects of the Scala language and standard library. I love Scala's collections and miss their power and ease when I'm writing Python. (Which I still do for certain scripting tasks and for accessing Python-ecosystem libraries.)

  • Wkhtmltopdf: Command line tools to render HTML into PDF
    12 projects | news.ycombinator.com | 25 Mar 2021
    I tried using wkhtmltopdf for rendering my book https://www.handsonscala.com/ to pdf, but in general I found it pretty buggy and unreliable. Lines of text would get split between pages, some CSS like flexbox didnt render properly, font sizes and page scaling was sometimes off (e.g. a big image on a page would make everything else shrink), etc. In general it "worked", but it didn't work well.

    I ended up swapping in Google's Puppeteer library to render my PDFs, and despite needing a bit of plumbing to get my Scala build script talking to the node.js runtime, in the end it worked much better. Things looked the same in puppeteer PDF as they did in the browser, which is something I could never quite achieve with wkhtmltopdf

    HTML to PDF conversion is a common requirement in modern web applications. It allows users to save web pages, reports, and other content in a format that is easy to share and print. There are many libraries and services available for converting HTML to PDF, each with its own strengths and weaknesses. In this article, we will compare some of the most popular HTML to PDF renderers in Node.js, including Puppeteer, Playwright, node-html-pdf, and Onedoc.

  • How to build a WhatsApp AI assistant
    7 projects | dev.to | 26 Jan 2024
    This library works by creating an instance of WhatsApp web running inside an instance of headless chrome automated by puppeteer. In my testing, I ran into tons of compatibility issues when trying to use these dependencies inside anything other than a bare-bones Node.js + express server. Also, we can’t spin up a new instance of chrome and WhatsApp web each time a user sends a message, this will exhaust our allowed WhatsApp connections (4 max), not to mention that doing this will make the response times painfully slow.
  • Show HN: Quetta – A privacy-first web browser with enhanced ad blocker inside
    2 projects | news.ycombinator.com | 18 Jan 2024
    It's a tricky balance to strike. Obviously, krono, you're right: ff we're being generous the app launch GA tracker they use, they probably consider it shares nothing of value or identifiable, but strictly speaking it's not true that no data shared.

    I think the audit you do is actually valuable. In my company's product, BrowserBox^0 (also a browser, funnily enough! focused on remote isolation, privacy & security, and including Tor support), we don't collect anything but we want to add some kind of telemetry regarding usage so we can even basically know how many daily users we have (outside of licensed channels where it's tracked in the contract).

    Even tho we don't collect anything, we don't advertise "Zero data collection" anywhere, because of how sensitive I think this topic is. I think we really need to be solid on it, if we're going to say that. And to cover us, in the privacy policy, we say "we may collect some data for operational purposes to ensure the continued running of the service" (paraphrasing), even tho we don't.

    One niggle is that we use Chrome in headless mode (can also use Edge / Chromium), and while we appreciate the auto updating quality that Chrome has for security patches, we're cautious that maybe Chrome still collects telemetry and sends it to Google even with headless and correct flags (see for instance: https://github.com/puppeteer/puppeteer/blob/afb7d9eb5854e851...)

    I know it's not your job...but what's your advice on how to proceed specifically?

  • How to track anything on the internet or use Playwright for fun and profit
    5 projects | dev.to | 16 Jan 2024
    If you've read my previous blog posts or ever experimented with Secutils.dev, you might be familiar with the web resources tracking utility. This utility allows you to monitor changes in web page resources, specifically JavaScript and CSS. While it has a somewhat narrow security-focused purpose — detecting broken or tampered web application deployments — it may not be the type of tool you use daily. Nevertheless, it serves as a good example of what you can build with modern browser automation tools like Playwright and Puppeteer. If you're interested in digging deeper into this specific utility, refer to the following blog post series:
