I've poked around a while ago at some Calendly alternatives (specifically was lo... | Hacker News
I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • CSA: Be careful with NEW Firefox add-ons over long weekends
    Mozilla has a great security team and they have recently moved to HackerOne https://hackerone.com/. I don't understand where you get the basis for saying that mozilla employees don't work on weekends. Any facts or substantiation or just speculation? Source: about 1 year ago

    Depending on what type of cybersecurity you want to do, there's other ways to set yourself apart as well. Another way I'd get confidence in someone's abilities is if they've made bug bounties on bugcrowd.com or hackerone.com, for example. Even then, at big companies those people still have to go through HR just like everybody else. Source: almost 2 years ago

  • Start your own (side) business with open-source in mind
    Cal.com is an open-source event-juggling scheduler for everyone, and is free for individuals. - Source: dev.to / 4 months ago
  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: 7 months ago
