I recall that Costa Rican addresses are more like directions:

At least for the neighboring country (Nicaragua) it's like that. Sometimes the reference points are not even there anymore, as in the case of some old buildings destroyed in the Managua earthquake in '72

I recently got interested in installing a TTN gateway in my home and adding some temperature sensors.

Having played with LoRa years ago my thought was that there should now be readily available and cheap sensors. But to my disappointment everything seems to be a bit pricey which really surprised me. I can get a Zigbee temp sensor for around 15 euros, but Lora sensors cost around double that. I am wondering as to why that is?

This is pure speculation - I have no prove. I believe is also due to the target buyer: afaik the biggest adopters are municipalities and not general consumers.

Speaking of costs, are the public gateways actually free to use or does one need something like a sim card to use them? What prevents people from spamming messages at rates that completely clog the network?

If we are talking about the radio spectrum: Not much - other than the threat of the regulators showing up at your doorsteps after they found you with a van. If you are talking about the backbone so to say, it's not such a big Issue. The original packet-forwarder sends "json" over UDP. If you are using a packet-forwarder by one of the network operators, some of them are using MQTT (IP/TCP) as the transport.

Some gateways let you filter by network_id, this will not stop someone from pulliting/disrupting the radio spectrum, but it will stop your gateway from relaying those packets to your network-server.

A small trip down to memory lane:

My first OpenStack install was on a bunch of VMs. Got that to run following the official documentation. Got enough people interested in it, that I was "allowed" to salvage whatever hardware I could find and put in a Rack.

Getting Neutron to work was a head first intro to networks and in the end I had to learn how to configure actual network hardware.

After adding Ceph on top of old spinning disk, watching them die one after the other and the cluster was still up with performance not worst than the IBM-Stuff we were paying for gave me warm-fuzzy feelings.

Thanks to Triple-O, Fuel and most of the other "installers" at that time I learned that - the "big guys" don't know what they are doing either ;-)

At the end of the day, it took the "mystical" out of the cloud, and for Junior me that was good - it also saved me from the path management wanted me to go: Sharepoint developer/admin.

Bitcoin is tied to the physical world the same way every other currency is tied to the physical world. Right now you can transfer abstract value you have acquired without a 1-2% fee through bitcoin, which is much easier than doing it via a bank. For example a poker player needing to get 1 million dollars to Monaco to play a tournament would have to pay 1% (10,000$) and wait god knows how long if he went through the banks, with bitcoin that process is much smoother.

In reality that "poker player" would probably just get a line of credit at the casino[1]. Moving/Getting money is "hard" mostly if you are poor.

The first time I used helm was to set up JenkinsCI on a k8s cluster on AWS, and in the default configuration, it setup a public-internet ELB listener (with type=LoadBalancer) for Jenkins' internal JNLP port. Which pretty much means the public internet has root access to your jenkins cluster, by default.

I had crypto miners using my k8s cluster within a couple of hours.

That was also the last time I used helm.

You mean the helm-package you installed without reading the documentation? Hate the player, not the game.

SirMonkey commented on Mosquitto: An open-source MQTT broker github.com/eclipse/mosqui... · Posted by u/ducktective

tombert · 4 years ago

I've never used Mosquitto, but I have done a fair amount with Verne.mq [1], and I have to say that MQTT is downright pleasant to use in a lot of cases. I've not done a ton with it in "real world" situations, but I have used it for multiple hackathons, and I'm always impressed how little of a headache it is to build a decent "live" application with almost no effort.

If your frontend web project calls for any kind of messaging, I definitely recommend looking into trying MQTT before you jump straight into WebSockets. There's a good chance MQTT does what you need, scales better, can communicate over WebSockets, and will make your life easier .

I learned about them on my previous job. It's rather easy to cluster and the Web-Hooks are super easy to get started with. I don't know Erlang myself, but looking at the code and comparing it to some of the Java solutions, it seemed well structured and easier to understand/modify if I wanted to. The only "Issue" I have with it right now, is the "custom OpenSource license" they have.

I learned k8s with some NUCs we had laying around at work. Might be easier than Pi, but not as cheap. Some things I used: https://metallb.universe.tf/ (LoadBalancer) https://cilium.io/ (Networking) https://rook.io/ (Persistent Storage)

I'm curious how you're doing authorization in Envoy. Is it a JWT-based httpfilter?

SirMonkey · 7 years ago

The funny thing with envoy is that you can take the source of the authz service and build your own auth-mechanism for other protocols. We are doing that for MQTT
