over-egging AFDDs?

Well the sparks ARE RF.

You probably want to do a fast Fourier transform, and those are very compute intensive

only if you have access that allows downloads... (most library subs only officially give "view only" access)

Yup that would figure...

"The STM32 family of 32-bit microcontrollers based on the Arm® Cortex®-M processor is designed to offer new degrees of freedom to MCU users. It offers products combining very high performance, real-time capabilities, digital signal processing, low-power / low-voltage operation, and connectivity, while maintaining full integration and ease of development."

They also have lots of built in capabilities for use in safety critical applications like dual watchdog, backup clock, supply monitoring etc.

Looks like they haven't converted all their files to include DRM yet?

A couple of months ago, I used the "unofficial" method to download amendment1 for BS7671 (not BS7671 including amendment1 which is not made available) it was unreadable in sumatraPDF and would only work in AcrobatReader with the FileOpen plugin installed.

I've just tried opening that same file again today, and it has expired, so AcrobatReader bounces you here

ok interesting, not seen that... I have the AFDD doc for example, and can't see any requirement to open with a DRM plugin (opens in old version of acrobat, foxit reader, and in a browser internal PDF reader).

I have kept the AFDD doc I downloaded in 2019 and I re-downloaded it last night they're identical, neither are protected, but their newer ones (e.g. the BS7671 amd1) are protected.

I've long railed against the way Parliament has in effect outsourced so much "tertiary legislation" to the BSI and given them a licence to charge whatever they want for access to it. Sadly little interest in DIY these days among the political class.

I agree, and the documentarian is not cheap. Some years ago a colleague bought an ISO standard from the Polish equivalent of BSI at a much lower cost that from UK BSI. It had the identical French and English sections.

And the committees that write the standards (my father was on a couple and chaired one for a while) are made up of people employed by and at the cost of companies in the relevant industries.

Certainly the commitee that I served on had only one third of manufacturers. Another third were potential users and the remaining lot was assorted 'intersted parties'.

Are the documents still accessible on devices like phones etc, and are they compatible with screen readers?

(i.e. do they fall foul of not meeting requirements under disability legislation)

But none paid by the BSI! The standards are written by third parties, but the BSI charge prices that are prohibitively high for individuals and small businesses.

there was a BSI person present, but, since this was around 50 years ago, I am not sure, but I'm sure he chaired the meeting. The BSI also provided the premises in which we met.

The standard was proposed by one party, objected to by another, the BSI put it all together.

They run as a business (despite their monopoly positionm). The CEO's pay and bonuses last year came to £m1.2.

They provide windows and mac acrobat plugins and iThing and android viewers (sounds like they are standalone rather than plugins, not tried) no mention of Linux

No mention

From the FAQ

"Which operating systems are supported?

The FileOpen Client will work on Windows 7 or later, Mac OSX 10.9 or above, iOS, Android and Linux."

No mention but it might have a fighting chance since it seems to use adobe reader to do the rendering, and that can support assistive technologies.

Still most things are compatible with my screen reader OCR in the worst case! :-)

I have seen mention that there is the option to print one copy of a FileOpen protected PDF. Does that work on yours? (and to a PDF printer driver?)

From acrobat print is disabled, from within firefox, it will print a single page to pdf not the whole doc, you get the UI of their viewer printed into the output, and it looks like you can only print page #1
