Ctrl+i (Firefox) Not generally useful to show this by default, because nowadays most pages are dynamically generated and although it's technically easy to implement, the last modified header is typically not set to $now.

The variation in local noise between different locations is huge. As an apartment dweller and radio amateur, this is something I am fighting every day and in a densely populated environment, the noise floor changes all the time, depending o

Setting a dangerous precedent, especially doing this by default (no opt-in) needed. But then again, if the people who carelessly include 3rd party dependencies (i.e. playing with fire) are those who use CF... they probably won't object

Typical FMCW radars transmit very short ramps (microseconds) at a very long (relatively) intervals (several ten milliseconds), i.e. a duty cycle of less than 0.1%. In order to create interference between two radars, the ramps have to overla

I am running a few websites which have a simple feedback forms which POST to a simple PHP script that sends me an email. By filtering for a few keywords, you can get of 99% of the form spam. Deliverability has never been an issue for me sin

Depends on what's "usable" for you :-) This SDR won't be able to compete with expensive high performance receivers that have a lot of pre-selection, but there are many examples of low cost SDRs that do a surprisingly goo

Interestingly Wikipedia says the Morse version of it is Morse code "dah-di-di-dah-di, dah-dit" ( –··–· –· ) IMHO more common is to send "ESE" (. ... .) - and the other station replies "EE" (. .) https

KiCad. It's very stable and offers features that some of the professional programs lack. Extensive part library built-in, and easy to extend. Under active development.

If you find "wave hunting" this interesting but don't have a SDR / receiver of your own, there are plenty of (free to use) WebSDRs to get started: http://websdr.org/

Fantastic tool. It also has a command line version which has almost completely replaced `bc` for me.

From an average of significantly below 500k to almost 2.5M users. This drives up the global number of connecting users from approx. 3M to almost 5M. Hard to imagine that so many people in Germany suddenly switched to TOR, especially since t

There was an X flare at around 19 UTC: https://www.swpc.noaa.gov/products/goes-x-ray-flux Bands are still doing fine over here in Europe, but I guess the US was hit with it in full force.

As you can see if you scroll down the page (with many alerts of a similar magnitude in the last weeks), this is nothing unusual, solar disturbances of this level happen all the time. We are getting closer to the peak of solar cycle 25 and i

That would be really helpful because taken out of context, single words translated to English will often produce very confusing results. My suggestion would be to ditch the google links and provide a properly translated version that is reve

The description of this extension explicitly tells you it will do this (integrated email protection). Works as advertised?

95% happy with DuckDuckGo. For the rest, I resort to Google.

I may not be under the jurisdiction of the FCC :-) Some countries publish full records, others just names, others nothing at all.

On most sites I use my amateur radio callsign (HN is an exception). It's unique and very unlikely to be taken already.

As a solution in between, for those who want to include a OSM map on their website but don't want to put load on the official OSM tile servers, a simple tile proxy may be a good idea. I am using something based on https://wi

FWIW, for building your own private network, there is no need to rely on something like TTN (hosted by someone else - isn't that a contradiction in itself?). ChirpStack ( https://www.chirpstack.io/ ) is a very mature a

No screenshot, but when there were several messages you could go through them with the arrow buttons that are grayed out in the screenshot. Not very advanced but 'good enough'.

Oh yeah - when we finally had laid RG-58 coax from downstairs up to the attic around 2000, my mom used Winpopup to tell us kids to stop playing Duke Nukem and come down for dinner. Good times!

This is a mammoth task but an important one. I wonder if there's a way to collaborate with existing collections of historical Amateur radio data, such as the famous "QSL Collection" from Vienna: https://www.dokufun
