Recent uptime statistics of my Nostr relay at.nostrworks.com
https://nostrworks.com/images/uptime-2024-02-15.png
Obviously I had some troubles 2 months ago, but they have been resolved. Uptime was actually not that bad as it seems: The invoice page was often affected and also sometimes websocket connections. But after improving my NGINX config the relay is running stable again.

It’s an awesome tool, my father has one too, he showed me once, how to use it.

- reply

Oh no, this is embarrassing: I think I've finally found the problem and it has nothing to do with nostream. 🙈 It seems the main reason of my outages have been too low limits in my NGINX configuration (worker_connections & worker_rlimit_nofile). But thanks to your help I have improved swap and memory efficiency on the way. 🤙 I am 99% sure the problem is gone now. I'll wait some days and then document my findings in the issue and close it. Thanks for your help!

As usual we will have to wait for the official report. It is too early to speculate. Do you have an statistics that collissions on runways are becoming more frequent lately?

It seems I am back to square one: After removing rate limits no out-of-memory and no redis restarts had happened again. But still my invoice page goes offline now and then. No apparent entries in any logfile (nostream, nostream-cache, nostreamdb). 🤔

2023-12-29 20:15:41

- reply

Now I understand it, thanks. I just realized that I have some rather old default limit in my settings, that is not in the current default-settings.yaml with a duration of 1d. First I'll get rid of this, let's see if it helps. I will document your tips in my github issue. Maybe someone else is having similar problems.

2023-12-29 18:27:34

Great, I will try that.
Would it be okay for the app to use the following redis config:
maxmemory 2mb
maxmemory-policy allkeys-lru
From the docs: "all the keys will be evicted using an approximated LRU algorithm as long as we hit the 2 megabyte memory limit."

Thank you! You mean those?
limits.event.rateLimits[].*
These settings can requires GBs of memory on a rather small relay?

2023-12-29 11:40:13

- reply

It seems there is an out of memory problem. I have now added 16GB swap to my 16GB RAM, but it still happens. Available Mem (RAM) was mostly 12G, until suddenly:
kernel: [62794.439403] Out of memory: Killed process 1142634 (redis-server) total-vm:27478268kB, anon-rss:11599084kB, file-rss:0kB, shmem-rss:0kB, UID:999 pgtables:47208kB oom_score_adj:0
Does redis really use 27G? Would max mem limit help? How do I set Redis max memory in nostream?

Okay, I have problems as well. It seems Damus only reads a fraction of my contact list, maybe it is because of this issue. I need to investigat further.
But I would recommend to ALWAYS store the "/" at the ende of an URL, it is the correct serialized value of an URL, ommiting it is bad practice.
See the spec: https://url.spec.whatwg.org/#url-path-serializer

2023-08-06 20:04:19

- reply

But why do you strip the "/" in URLs? I think the serialized representation of paths always include the "/" so it would be better to append it, but to strip it.

2023-08-06 13:49:50

Thanks for your help. I am quite sure it does not have anything to do with relays, in my case. I was connected to the same relays, checked back and forth.
Now I have uploaded my old contact list using gossip (it can merge and push your contact list) and Damus still shows a higher number but still not the correct one.

2023-08-06 12:11:49

My following count is decreasing every day. But I haven’t unfollowed anyone by purpose. Seems to be a bug in the contact list. Other clients than Damus show larger followings, interestingly. 🤔

Well, eVTOL are suitable only in specific cases, where vertical landing is really required, usually it’s not. In all other cases: Airplane aerodynamics win!
There are already prototypes like the Elektra One (with solar) and the Elektra Trainer (2 seats) with up to 3 hours and more flight time. It is only a matter of time.

2023-08-05 20:58:21

Here it is, another post about my journey to becoming a pilot! #LearningToFly
In my previous post, I mentioned that the desire to learn how to fly has been with me since childhood. However, recent concerns about the CO2 impact of flying made me pause and reevaluate my dream. I've taken steps to reduce my personal carbon footprint and fly less frequently. Considering that aviation is responsible for approximately 2% of CO2 emissions, it's essential to weigh this impact. Interestingly, only 5 to 10 percent of the Earth's population takes flights within a year, which highlights the imbalance. These thoughts led me to reconsider my long-held aspiration of becoming a pilot.
But then, quite serendipitously, I discovered that a local flying school has one of the first electric aircraft in its fleet: the Pipistrel Velis. This remarkable aircraft was the first fully electric type certified aircraft by the EASA (European Union Aviation Safety Agency) in June 2020.
Shortly after learning about this, my wife convinced me that the time was right, and she enrolled me in the flight school. :-)
Last week marked my fourth session, the third of which was on the Velis, and I must say it's truly amazing. It bears a striking resemblance to an electric car: no fumes, no loud noises (unlike flying with combustion engines that require noise-canceling headphones to communicate with your co-pilot), and no vibrations at all. The freedom of flying without the distractions of a combustion engine beside you is exhilarating.
The only drawback: Electric aircrafts are not yet suited for extensive A to B transport. The Velis has a flight time of approximately 50 minutes. During flight training, you initially focus on the "circuit": taking off from and landing at your airfield, conducting rounds in the vicinity. Much practice in this pattern is required before attempting landings at different airfields. So it is well suited for flight schools.
With this groundbreaking aircraft, I'll managed to halve my emissions during flight school, and I find that truly inspiring! To pioneer new endeavors, someone has to take the first step. I'm grateful that Pipistrel developed this electric aircraft, thrilled that my flight school offers it, and I am excited to participate in this electrified future of aviation!
On a related note, numerous electric aircraft are in development, set to allow A-B flights with extended ranges. I'll delve into these advancements another time.
So, what are your thoughts? Do you believe electric aviation is the future?
For those who've contemplated learning to fly, what factors have deterred you from pursuing it?
If you're a pilot, what motivated you to embrace aviation?
I'm eager to hear your thoughts!
This is me during my first session with the Velis:

This is really incredible, especially the rescue on sea. Thanks for sharing!

2023-08-03 16:36:47

Yes, the Pipistrel Velis has a flight time of only 50min but largely depends on your cruise power. It has 2 batteries and you have to land with 30% state of charge. That way you can still do a go-around and complete another circuit.
So the Velis is only suitable for very short trips or local flights. Therefore, they are mainly used in flight schools. You can perfectly learn traffic patterns with it.
I really enjoy flying with the Velis. It is super quiet (compared to a internal-combustion engine) and it has noticable fewer vibrations.

2023-08-03 16:22:45

- reply

Thanks for your clarification. It still seems unpossible for me to bring an aircraft safely down with a parachute. 🤯 On the other hand those modern aircraft are so light. The Pipistrel Velis, I am flying, has an empty weight of only 428kg. So cool.

I don't think it makes much difference if salt contains 99% NaCl or 98% NaCl! Most high priced salts are not worth it. But yes, salt can be a good carrier medium for trace elements.

No, I don’t have any plans to become a professional pilot, hobby only. I am happy with my occupation and would not trade it. Maybe, I I’d even be bored as a commercial pilot. 😅
But maybe I’ll fly to some business trips one day. Although there are many additional licenses needed to do that.

Some weeks ago, I decided to fulfill a childhood dream: #LearningToFly! ✈️
Encouraged by the awesome Nostr community, I decided to share some experiences on my way to my private pilot license. I hope my journey is interesting to those pursuing the same goal, to aviation enthusiasts, and anyone else curious about it.
Feel free to ask me questions, and I'll do my best to answer them. As I am still early on my journey, there is much for me to learn.
First, I'd like to tell you about my childhood dream. Becoming a pilot used to be a childhood dream for many children. I don't know if it is still a thing. For me, it was something to aspire to.
When I was 10, I could identify almost every airplane model that landed at Vienna airport. While other kids played store, I set up a flight office in my room. You could buy flights from me! Unfortunately, I have no photos to share. However, here is a picture of a widely used airplane by Austrian Airlines, the McDonnell Douglas MD-82. I also had a small model of this aircraft and others.
https://upload.wikimedia.org/wikipedia/commons/7/7e/McDonnell_Douglas_MD-82%2C_Austrian_Airlines_JP5962505.jpg

As time went by, my interest in becoming a pilot faded, though I still liked planes. However, becoming a pilot seemed less interesting as I grew older. Now, I have my own consulting company, and I am content with my career choice.
Nevertheless, learning to fly was always on my agenda. However, as a child, I was too young. In my twenties, I lacked sufficient funds. In my thirties, I had no time or didn't prioritize it. Additionally, my concerns regarding flying grew due to its massive CO2 impact. But this year, something changed that reignited my dream. It has to do with a revolutionary new way to fly. I'll share it with you tomorrow.

So, let the journey begin: #LearningToFly
Maybe I shall start with the beginning, why I am actually learning to fly. But I’ll do this tomorrow. For now, just a photo my wife took some minutes before I crawled into the plane to experience my first flight as a #PPLA student! 👨‍✈️✈
Here I am going through the checklist. That’s what a pilot needs to do before every flight. And you really need to do this. It is not like we all did when learning to drive: going around the car, but never doing it again after we have the permit. When it comes to flying, safety is paramount. You can’t stop an airplane in midair. 🤷‍♂️ https://cdn.nostr.build/i/0d0436a600724829f174fae916e9e436556a95dc762067ef5bbec4ede1c1f829.jpg

I love the tech and prospects behind Nostr. I run a relay and I support clients by translating the UI. But for me, personally, Nostr is lacking interesting content.
So, maybe I should post more content here, that I care about and others might find interesting?
Some weeks ago I started training for my private pilot license. Maybe that’s a topic some might be intersted in. Pictures of small airplanes, pictures of the world from above and some insights from a student? Anybody interested? Give me a 🤙 or a repost. Thanks!
