Hi there, I’m just your average HN user from Patras, Greece.

Interested in computers, technology, science and similar topics. Curious about astronomy, maths, geography, philosophy, religion, photography, science fiction and many many more.

You can find me usually on Twitter (yes, I know it’s called X nowadays) or have a look at my own webpage and Linkedin for contact details.

I’m a software/telecoms engineer, currently employed but always open for any interesting proposals for remote only positions ;-)

NKosmatos··on Tracing a powerful GNSS interference source over Europe
TLDR (conclusion from the paper): "By a combination of these techniques the satellite Cosmos 2546 (NORAD ID 45608) was identified with high confidence as one source of the interference. Further analysis pointed to the Russian Edinaya Kosmicheskaya Sistema, an early warning constellation to which Cosmos 2546 belongs, as collectively responsible for the wide-area transient interference causing GNSS degradation across Europe since 2019."
NKosmatos··on Ask HN: We just had an actual UUID v4 collision...
> I thought this is technically impossible

Actually it's not impossible, but very very improbable.

P.S. You should play a lottery/powerball ticket

P.P.S. Whenever I use the word improbable, the https://hitchhikers.fandom.com/wiki/Infinite_Improbability_D... comes in mind

NKosmatos··on Revision Demoparty 2026: Razor1911 [video]
I upvote every post related to the demoscene due to my age, so I couldn't let this one, especially when it's coming from RZR. Imagine if we could get a new release from FC as well in 2026 (40 years since their founding)!!!

More about Razor 1911 and Future Crew for the young readers of HN: https://en.wikipedia.org/wiki/Razor_1911 https://en.wikipedia.org/wiki/Future_Crew

P.S. Too many groups to mention, but these two hold a special place in my mind ;-)

P.S.2. Extra mention to the most famous Greek demo group - ASD (Andromeda Software Development) - https://www.pouet.net/groups.php?which=1317

NKosmatos··on Our commitment to Windows quality
Is this a joke? Is this guy for real? And he calls himself a REAL engineer? He’s a manager doing damage control because all this time Microslop is greedy and has stopped caring about power users.

We’re not first time users, we don’t want Microsoft BOB as our UI, we don’t want ads and internet search “functionality” in our Start menu, we don’t want AI everywhere and we don’t want things hidden from us.

Make Windows 11 Pro for real pro users and 11 Home for new users. I hope a few people from MS are reading this, especially Mr Engineer.

I’m going to get downvoted for this, but I don’t care.

P.S. Yeah yeah guys, I know about Linux ;-)

NKosmatos··on Places to Look for Alien Life
Direct link to the paper: “ Probing the limits of habitability: a catalogue of rocky exoplanets in the habitable zone” - https://academic.oup.com/mnras/article/547/3/stag028/8526432
NKosmatos··on Layoffs at Block
I totally agree. In this strange era we're all in, it seems that not using proper capitalization is a sign of "importance". Other high ranking people/CEOs/technologists don't use the correct rules, especially for important announcements like laying off 4000 people. O tempora, o mores!
NKosmatos··on Unsung heroes: Flickr's URLs scheme
I agree 100% with the author, clean, easily readable and well structured URLs make the web a better place. URL is a hierarchical structure as introduced in the RFC1738 by a guy you might have heard, Tim Berners-Lee, the inventor of the World Wide Web :-) https://www.rfc-editor.org/rfc/rfc1738

Easily readable URLs is something I learned in the 90s and I still try to enforce in everything I create.

NKosmatos··on Ask HN: What happens after the AI bubble bursts?
AI is here to stay but not in the way big corporations dream of it. People will continue using AI but when the AI bubble pops, sooner than later, things will stabilize and adapt to real usage with a different business model.

As you correctly state, the cost of AI as a Service (AIaaS) will increase for end users, but this isn't necessarily a bad thing. It will allow the "real" users to continue having access to it and sieve out the ones who are just playing around. Prices for RAM, GPUs, SSDs will normalize a lot and more people will move towards local models.

Similarly to what happened with the dot-com bubble (I saw it happening), it doesn't mean that everything will disappear, but that it will change/adapt. All of us AI realists are currently being treated like technophobes when we say things like that ;-)

NKosmatos··on I started programming when I was 7. I'm 50 now and the thing I loved has changed
Being a similar age with the author, I can relate with many things (like so many people in the comments below). The writing style is a bit strange and as mentioned by others, it might have been (re)written by AI, but the message is still there.
NKosmatos··on New YC homepage
Impressive! Seeing all the before and after photos is a nice touch. With regards to the actual web page, white text on light background (partners part) makes it nice easily readable.
NKosmatos··on Show HN: Free AI Image Upscaler (100% local, private, and free)
Thanks for posting this, there are also some other helpful (free) tools on the same page.
NKosmatos··on Henley Global Passport Index 2026
Article with more insights and details: https://www.henleyglobal.com/newsroom/press-releases/henley-...
NKosmatos··on Periodic Spaces
Just opening this page is a "heavy" benchmark for your PC/browser :-)
NKosmatos··on Cloudflare was down
LOL, 500 returned for many big sites…this is going to hurt and make people rethink. If it’s not DNS, then someone pushed to production on Friday :-)
NKosmatos··on N-Body Simulator – Interactive 3 Body Problem and Gravitational Physics
Love this, reminds me of a Windows program (whose name I’ve forgotten) that I was playing with some decades ago… Solarwinds or something similar. You could add planets/masses and play with orbits, trajectories and all sort of options.
NKosmatos··on Human Fovea Detector
What kind of sorcery is this? Incredible visualization!
NKosmatos··on Win11Debloat – declutter and improve your Windows experience
The https://massgrave.dev activation scripts have support for various versions and also for enabling Extended Updates (ESU), but this is a bit off-topic and HN mods might come after us ;-)
NKosmatos··on Old Western Digital SMR hard drives have vulnerable firmware
Original article in German: https://www.030-datenrettung.de/kritischer-firmware-fehler-b...
NKosmatos··on Exploring IRC (Internet Relay Chat)
/me remembers the good old days of IRC, the netsplits and all the other good & bad things of the internet wild west…
NKosmatos··on Today is when the Amazon brain drain sent AWS down the spout
This is how articles should be written, this is why I’m reading El Reg (a.k.a. The Register) all these decades, this is what happens when high management cares only about profits and when real engineers don’t eat the RTO bullshit. Bravo for putting this online.

P.S. I’m not an Amazon hater, replace the company name with any other big one of your choice and the article will have the same meaning ;-)

NKosmatos··on Synology reverses policy banning third-party HDDs
After all the complaints and upheaval created after their silly management/leadership decision, they finally understood something.

As an owner and administrator of many Synology NASes I agree that Synology offerings are a bit underpowered compared to what is available in the market (from H/W point of view), but the ease of use and peace of mind within the Synology ecosystem (DSM software, apps) outweighs whatever drawbacks they have.

If Synology management takes the decision to refresh their H/W with new CPUs, NICs and more RAM, I'm sure they'll stay on the market ;-)

NKosmatos··on Show HN: Timelinize – Privately organize your own data from everywhere, locally
Nice one, thanks for sharing. For sure I’ll give it a try.

Have you thought of creating a setup so as to package all libraries and dependencies needed? You have a very nice installation guide, but there are many users who just want the setup.exe :-)

NKosmatos··on Fire destroys S. Korean government's cloud storage system, no backups available
Thanks for this, it gives a lot of extra info and content compared to the original article.
NKosmatos··on Magma Displacement triggered Earthquakes around Santorini

NKosmatos··on Show HN: The text disappears when you screenshot it
Nice one, the good (great?) thing is that you can save this as a plain old html and you've got the whole code :-) It hasn't got any type of license included or any other info as comments, so perhaps the creator or the OP can let us know.
NKosmatos··on William Gibson Reads Neuromancer (2004)
That's why like-minded HN users are here ;-)

I uploaded your MP3s to Internet Archive for all to enjoy: https://archive.org/details/william-gibson-neuromancer-abrid...

NKosmatos··on Nano11 cuts Windows 11 down to size, grabbing just 2.8 GB of disk space
NTDEV has helped many with his efforts of creating tiny versions of Windows. This is the case for other solo developers/maintainers of useful programs. Unfortunately big companies don’t seem to care, imagine what would happen if all these talented people got some funding from big corporations.
NKosmatos··on Aurora season and the Russell-McPherron effect
The original paper from 1973, albeit behind a paywall :-(

https://doi.org/10.1029/JA078i001p00092

Use your preferred true open library to get it ;-)

NKosmatos··on The demo scene is dying, but that's alright
The scene is not what it used to be, but it's still alive and will remain for decades. We "old-timers" were lucky to be around the 90s when the demo groups and parties were on full swing.

There are many groups and parties to mention, but for those interested have a look over at: https://www.pouet.net/toplist.php
