<p>Very interesting article. After 12 years of almost daily cycling in the Netherlands, I recently started driving a car as well. I always appreciated the Dutch civil infrastructure, and this new experience only adds to my admiration.<p>Compared to other European countries, driving in NL definitely requires extra attention. There are many small & vulnerable participants sharing the space, moving in different directions with much less inertia than cars. On the other hand there are plenty of buffer zones, the lanes are cleverly organised and clearly marked, and there's 30 kmh (18 mph) limit in most streets in the city. A smaller car with great visibility is really useful here.</p>

<p>Hello HN!<p>I would like to show you a tool I made for sysadmins, developers, web entrepreneurs, and all of us in between these categories who care for the uptime and performance of our web services. Binocs [1] is an Uptime Monitoring tool for people who spend their workdays on the command line and are obsessed with accuracy and reliability.<p>When I started using the existing uptime monitoring solutions for the services my team and I were responsible for, I thought the world didn't need another such tool. Then I changed my opinion, as I became disappointed by the reliability and general quality of the existing tools. I tried to make an uptime monitoring tool that is reliable and fits the modern dev/ops toolkit.<p>Binocs provides the standard features you might expect from an uptime monitoring tool, plus a modern command-line interface [2] and a Terraform provider [3]. Binocs gives makers of the internet 24/7 insight into the availability of the services they care for and notifies them - via the usual communication channels such as SMS, Telegram, or Slack - if any of these services become, for whatever reason, unavailable. Binocs monitors uptime, apdex, and response time (broken down to its basic components) from any custom set of geolocations the user selects for each check.<p>There are binaries available for major platforms and architectures [4].<p>Binocs is written in Golang and relies on TimescaleDB for storing and aggregating time-series data. The solution is highly redundant and hosted on AWS (hybrid deployment is on the roadmap). The algorithm meticulously strives to eliminate both false positives and false negatives.<p>If you want to try Binocs, only an e-mail address is required to sign-up. We use passwordless authentication. Every new account gets 250k free credits [5].<p>You can also watch a short video demo [6].<p>Any feedback is much appreciated, and I'm, of course, open to technical questions as well.<p>[1] <a href="https://binocs.sh" rel="nofollow">https://binocs.sh</a><p>[2] <a href="https://binocs.sh/documentation" rel="nofollow">https://binocs.sh/documentation</a><p>[3] <a href="https://registry.terraform.io/providers/automato-io/binocs/latest" rel="nofollow">https://registry.terraform.io/providers/automato-io/binocs/l...</a><p>[4] <a href="https://binocs.sh/downloads" rel="nofollow">https://binocs.sh/downloads</a><p>[5] <a href="https://binocs.sh/pricing" rel="nofollow">https://binocs.sh/pricing</a><p>[6] <a href="https://youtu.be/TsHvTbsFWtg" rel="nofollow">https://youtu.be/TsHvTbsFWtg</a></p>

<p>Yes, the branching corals are the fast-growing early colonisers. The habitat they create is attractive for fish and invertebrates. Together they make up a reef ecosystem. The resilient reef-building massive corals typically appear on the reef later and grow much slower.</p>

<p>I believe you could explain greenhouse effect to consumers and voters. The basics are elementary/highschool physics and chemistry. And there are useful analogies too. The issue is that schools in too many countries don't seem to try to explain mechanisms of climate change to pupils.<p>> It's easy to take action against an asteroid, but fighting CO2 emissions is far trickier.<p>Really?</p>

<p>When I was a child, everyday so many things were new for me, summer holidays took seemingly forever because there was a small adventure behind every corner. Interactions with people and the nature were very often memorable, instructive, sometimes life-changing. Food was usually some kind of experience, sometimes even frightening. Using different tools and machines for the first time, mindblowing superpowers in my hands. Getting hurt in various ways for the first time. Emotions, learning, surprises, memories, touching and tasting and smelling the wonderful world. That was the childhood.<p>Then the adulthood arrived - a successful one so far. But during the adulthood, days started to went by noticeably faster. I couldn't tell what I had for lunch two days before, how I spent last Monday or how I felt two months ago. And I started to understand why old people say that life unfolds slowly when you're young and then years pass like weeks. I think this happens to many people once they no longer (or rarely) meet the unexpected, try new things, get kissed/hurt/deceived/smiled at/laughed at/gifted/fed/etc/etc in previously unknown ways in different settings. They start making far fewer memories compared to when they were kids.<p>When I started traveling to different countries and cultures, I realised that - at least for me - this is bringing back my childhood wonder and the slow passing of time. I can sit a whole day on a pavement in Cambodia and watch the street, or watch the day in life of a Cuban fisherman, or eat fruit or insect that I have never heard of before, feel and hear the morning around a Buddhist temple, then Hindu temple, Confucian temple, learn scuba-diving and see on my own eyes what we've done to the marine world, or spend a night with my wife on a train station in the middle of nowhere, and it all has a profound impact on who I am as a person, a friend, a partner. I cannot tell exactly who I would be if I have spent these days in the small Czech town where I grew up, of course. After having done some 3 years of traveling (backpacking mostly) I am very likely less bored, less scared of the unknown, more curious and definitely feeling very much more alive and appreciative of what the world and especially the natural world really is. This personal experience cannot be substituted by literature, documentaries or local meetup groups. But I understand that for some people these may be enough. I would rather never come back to live in one place than stop traveling entirely.</p>
