I've been playing around with crystal for years, and absolutely love it (I'm a full-time ruby dev using Sequel as an ORM). I wish I had more time to spend with crystal. Kemal (referenced above) is really good, and excellent with

I agree, and I can't believe more people haven't mentioned it here. I am not going to rehash what anyone can read at the linked site, but it seems like an absolutely great project, and seems to be flying under everyone's rad

I tried Strava, but it just wasn't detailed enough for me. I ended up finding smashrun.com. Granted it's only for running, but it's phenomenal. I've been a subscriber for years now, and I can't say enough posit

One thing I've found useful when listing tables that you can't exactly remember the name, you can use wildcards. \dt cust* will list all tables that start with "cust". It works with other commands as well (like \l). Als

I can't figure out how to get it configured as a pager (in postgres). I've been using pspg set in my .psqlrc. I changed it to \setenv PAGER 'vd' and I just get a big chunk of text with no ability to navigate columns. H

I started using (and subscribed to) Inkdrop[1] after recommendations here and have been very happy with it. Yes, it's $5 a month, but it automatically syncs (encrypted locally first), and has a way of doing full local directory backup

I actually started binding my CAPSLOCK key to F5, and I have F5 set as a tmux attention key, but I've never had too much problem with left pinky finger hitting escape.. A side benefit of this is that F5 is mapped to refresh for a lot o

Your comment totally reminds me of an article Tim Urban wrote in 2015 about the dangers of AI (Mr. Urban, if you are around these parts I absolutely love your writing!!). Within that article he describes "a 15-person startup company ca

That is a phenomenal article about timezones in general that apply to any database, as well as a great explanation of features specific to postgres. It is interesting that a timestamp without timezone is internally represented a timestamptz

There's a really cool way to do this that I learned about with ruby here https://gist.github.com/O-I/3e0654509dd8057b539a Here's a quick demo class that shows the technique. It's amazingly simple. clas

I think you're right. I run basically the same route every time (varying distances a bit), through a county park that's literally down the same sidewalk where I live. I also listen to the same six or seven songs, changing a few

I'm going to answer my own question - I tracked it down to a bug in lattice-core that occurred when it couldn't parse incoming JSON, and for some reason it killed the socket server. I fixed it by rescue the JSON parse and all is

I answered this on a different thread, but I've specifically designed things for this scenario. The framework has a class named WebObject. Once instantiated, it stays persisted on the server, and can take on additional subscribers. A

Yes, you are completely right. It should have been titled "Realtime-first development with Websockets".

by jasonl99 10y ago
Short answer, I don't know. I don't know that they'll disappear, they are just so efficient. That said, lattice is completely event-driven. The #on_event and #emit_event methods act as entry and exit points. As long as I c

Author here...Well, I started down the websockets path because of how awesome I found crystal to be. I wasn't intending to do this a few months ago, it just sort of took on a life of its own :) The framework as I've written take

I haven't explored that a lot, but my thought was that the amount of setup/teardown for polling goes away, so it's at least an order of magnitude (guessing) better. I have written the framework to use a single socket connecti

A few months ago I bookmarked a 1923 talk/essay by Bertrand Russell that is actually entitled Vagueness. I thought it was extremely interesting to read the perspective of a cleary-brilliant thinker prior to the computer age. http:&#x

I couldn't agree with you more. I can't even tell you how many times I've figured out something while on a run or walk -- far too often I've started writing code without thinking it through adequately. Getting away fro

I have a 2013 Jeep Wrangler, that while unrelated to the hacking incident, is quite disturbing in its own right. An Atlanta TV station did a story about the TIPM (Totally Integrated Power Module): http://www.wsbtv.com/news&
