If you're managing linux servers (or desktops, even), I highly recommend this firewalling suite called CSF/LFD. Been using it for decades, and it has protected 'my' linux machines better than anything else ever could. Proud to say none of the systems I manage have been compromised, hacked, broken in to or ransomwared. CSF is easy to install and comprehend even for linux noobs, has well written documentation and does what you hope it does and usually better! It offers an integrated webserver user interface, or integrates in existing control panels (like webmin). And amazingly it's still completely free! https://configserver.com/configserver-security-and-firewall/ I have not been paid for this. It's just out of sheer appreciation and being thankful for all the hard work that its devs have put into it which made me decide to post this.

Population declines of Earth's species: 56% of mammals (32–75%) 53% of birds (48–56%) 63% of amphibians (43–75%) 54% of insects (13–89%) 41% of fishes (11–84%) 28% of reptiles (14–63%) 'the magnitude of the Anthropocene biodiversity crisis is considerably more severe than suggested by analyses based on IUCN Red List conservation categories.' The scientific consensus: economic growth and the race for profit mean extinction. 'the planet is approaching a mass extinction event far graver than prior research has suggested' https://phys.org/news/2023-05-anthropocene-sixth-mass-extinction-event.html The International Union for Conservation of Nature (IUCN) says '28% of species are under threat'. However, a third of species currently classified as non-threatened on the IUCN Red List 'are actually spiraling toward extinction'. https://www.euronews.com/green/2023/05/26/almost-half-worlds-species-seeing-rapid-population-decline-study-finds Scenario-based climate projections considering the most critical life stages (spawners and embryos) clearly identify the temperature requirements for reproduction as a critical bottleneck in the life cycle of fish. http://web.archive.org/web/20221206235031/https://amp.theguardian.com/environment/2020/jul/02/fish-species-survival-climate-warming-study 60% of primate species are threatened with extinction, 75% are declining. Main threat: habitat destruction due to logging/agriculture. Hunting, road construction, oil & gas extraction, mining, pollution, disease, and climate change are also key threats. https://theconversation.com/60-of-primate-species-now-threatened-with-extinction-says-major-new-study-71441 Our predicament is now so grave that only extraordinary economic system change towards a low energy set-up will do if…

Blijft leuk ;) Interessant om te vermelden was dat die 'storingen' niet uit de zelfbouw zender kwamen, maar dat ik heel dicht bij een Centraal Antenne Systeem, een voorloper van kabeltelevisie, woonde, en dat de signaal-versterkers die daar toen gebruikt werden niet waren opgewassen tegen sterke hoog-frequent straling (ongeacht de golflengte van die straling). Het was niet zo dat de 'harmonischen stoorden op de luchtvaart- en TV-banden', zoals toen *altijd* werd ge-opperd in de rechtzaal. Er zaten zgn band-pass filters aan de uitgang van mijn zender, daar konden evt harmonischen niet eens doorheen komen. Van de 18 Watt output van de eindtrap bleef nog maar 10 Watt over voor de antenne, zo sterk waren die filters. Iedereen die ooit met hoogfrequent zenders en ontvangers heeft gewerkt weet dat gevoelige antenne-versterkers (t.b.v. ontvangst van ver weg gelegen TV-zenders) niet tegen sterke HF-straling in de nabijheid kunnen, en al helemaal niet als een kabeltelevisie richt-antenne precies jouw kant op staat, terwijl jij met een FM-zender aan het stoeien bent..

Try not to be insulted by the headline. I wrote this because it is slowly becoming mainstream to be scared of 5G, which is - honestly - really stupid. Most people complaining about the bad effects of 5G, 4G, microwave, wireless internet etc. have not been enjoying any education in basic physics. I'll try and explain why in simple to understand language; "How can we be so sure that many diseases are not being caused by the radiation poisoning now occurring from cell phones, 5G towers, EMF’s in the home (wifi, microwave ovens, refrigerators, digital meters etc) at the office, on a ship (many now have onboard 5G), at a concert (with tens of thousands of cell phones in use in close proximity)?" We can be quite sure of that because the radiation you refer to can easily be measured. Both in strength and in frequencies used by these devices. Prior to the growth of cable-TV, digital radio, wireless internet, smartphones, 2/3/4/5G UMTS, the air around us was literally loaded with actual TV signals (VHF/UHF) and FM/AM radio transmissions everywhere. Really powerful ones, from local radio- and TV-stations all the way up to nationwide transmitters. Most of those transmitters pumped…
