Found this through a BBC news article where some German Professors were arguing that the dominance of English in scientific discussion could be as detrimental as that of Latin a few centuries ago.
My personal experience, although German can be challenging and mine is not particularly strong hence why I try to watch Die Sendung mit Der Maus ( the kids science programme) every week to improve it, is that knowing even a small bit has benefits – particularly outside of formal education (such as on hobby electronics and engineering/science websites) as well as computer security blogs, there is much better in depth content to be found in German – the complexity of the language itself makes “dumbing down” impossible.
As an example reading a booklet from Siemens about electric distribution networks and the apprentices training manual from Die DBP-Telekom from the 1980s helped me finally crack the mystery of why one site at work is particularly plagued by electromagnetic inteference and how this could be mitigated as part of new building works…
Last year Ofcom UK warned folk “the cheap China fairy lights and LED lamps might cause your wifi to act up” and added a few paragraphs of non specific info.
Today I was reading two blogs from German speaking radioamateurs; who found some of the various new eco friendly lamps made a rough noise on their shortwave receivers.
Two of them (one in DE, the other in CH) painstakingly set up an experimental lab complete with monitoring antennas and spectrum analysers; and posted up their results (showing QRM (interference) into VHF frequencies (including those used by DAB radio) and a critique on the LED driver circuit (which when used on a TN-C-S electricity network with combined neutral and protective earth is likely to upset all radio reception throughout the entire building where such lamps are used…
EDIT: the Philips lamps are in fact better types than other brands (although there are plenty of cheap unbranded energy saving lamps which do create bad interference); and one of the chaps involved turns out to be a Professor who works in a lab that tests equipment for EMC compliance as his day job…

Companies should be careful when making such claims cos there is always at least one person out there that is gonna put your shit to the test in ways you couldn’t imagine, and you better be fucking right…..

increasingly it seems to be the Asians and folk in the German speaking countries who do this kind of testing (even for their hobbies).
To be fair on the lamp manufacturers; they only claimed the lamps generate light and use less energy than the old style glow lamps; and it is only recently with wider use of CFL and LED lamps that EMC issues have been discovered.
Various other devices also cause QRM – laptop chargers and computers themselves, solar panels that feed back electric to the grid (these work like a computer PSU in reverse). The circuits used to convert lower DC voltage into strong AC voltage have always been notorious for this side effect and many manufacturers (especially US based ones) omit only a Euros worth of components that would reduce the problem (which was well known by 1985!)
As well as being a great nuisance to those who are also interested in radio and/or hi fi audio as well as computers and electronics, bad equipment (particularly power line networking) threatens the privacy of computer users – the unwanted signal can be monitored and decoded from hundreds of metres away!
