Neither the EU, nor its member states, have the power to make investment decisions on behalf of private companies.

The extra investments pledged under the trade deal would come from private companies, which Brussels conceded it has no power to control.

That's not really up for the EU to decide on.

sasvarion KOReader Document Viewer for E Ink devices

> 1. I already have an ebook library in Calibre that I access on other devices, the sync feature allows me to seamlessly integrate into my other devices.

just out of curiosity: I sync my Kindle with Calibre in a very seamless way, too. what is the main difference here?

sasvarion The reMarkable as a notebook and eBook reader

> 1. Custom file system: this means I can ssh into it, but I can't rsync my bibliography into it, since it won't display regular pdf files whose name is not hashed and registered in some sort of index. Moreover, the lack of a Linux client meant it was very hard to put my pdfs on it, or extract my notes from it.

FWIW, rmfuse [0] allows you to mount the reMarkable cloud and you have easy access to sync with real filenames.

[0] https://github.com/rschroll/rmfuse

> RMfuse provides access to your reMarkable Cloud files in the form of a FUSE filesystem. These files are exposed either in their original format, or as PDF files that contain your annotations. This lets you manage files in the reMarkable Cloud using the same tools you use on your local system.

sasvarion A digital logic designer and circuit simulator

Not really sure what you mean with heavyweight, but it is simplistic according to your requirement:

write input config files (here: in VHDL) for the simulator (ghdl), and then view the output after x clock ticks (with gtkwave).

sasvarion A digital logic designer and circuit simulator

Been a while since I've been running this, but you can patch something together with GHDL [0] (or Xilinx's simulation suite (ISim)).

Define your circuit with VHDL/Verilog, create a testbench, run the scripts and export to VCD, and then look at the waveforms with GTKwave [1] or your waveform viewer of choice.

sasvarion Keeping a Bibliography

you might wanna have a look at pubs [0]. It is a command line bibliography manager.

The folder structure looks like this:

  ~/.pubs/
      bib/
      doc/
      meta/
      notes/

The bibkey is the filename for the different files in those folders, and for notes you can use markdown. You can then keep your pubs folder under version control (or symlink the (sub)folder(s) to wherever).

sasvarion Ask HN: What are some of the best technical talks you've heard?

Free Electron Lasers

...or why we need 17 billion Volts to make a picture.

https://media.ccc.de/v/34c3-8832-free_electron_lasers

HN discussion: https://news.ycombinator.com/item?id=16028723

Wouldn’t it be awesome to have a microscope which allows scientists to map atomic details of viruses, film chemical reactions, or study the processes in the interior of planets? Well, we’ve just built one in Hamburg. It’s not table-top, though: 1 billion Euro and a 3km long tunnel is needed for such a ‘free electron laser’, also called 4th generation synchrotron light source. I will talk about the basic physics and astonishing facts and figures of the operation and application of these types of particle accelerators.

Most people have heard about particle accelerators, most prominently LHC, at which high energy particles are brought to collision in order to study fundamental physics. However, in fact most major particle accelerators in the world are big x-ray microscopes.

The latest and biggest of these synchrotron radiation sources which was built is the European XFEL. A one billion Euro ‘free electron laser’, based on a superconducting accelerator technology and spread out 3km beneath the city of Hamburg. The produced x-ray pulses allow pictures, for example from proteins, with sub-atomic resolution and an exposure time short enough to enable in-situ studies of chemical reactions.

This talk aims to explain how particle accelerators and in particular light sources work, for what reason we need these big facilities to enable new types of science and why most of modern technology would be inconceivable without them.

sasvarion Sean Parker unloads on Facebook “exploiting” human psychology

  It's getting harder and harder to "just don't use" social media.

I don't know about the business perspective, but why is it hard not to use facebook for people? It's a serious question. Everybody I know (me included) who is not on facebook has no problem with it, and it certainly isn't getting harder.

sasvarion Signal’s Moxie Marlinspike calls out Telegram founder Pavel Durov

The apk can be directly downloaded on their website [0]. It is signed by OWS, runs without gapps installed via websockets and should be 'auto-updating'.

f-droid would be nice, I agree. I did not really follow the whole political discussion about why moxie refuses to cooperate, but at least I can use signal again after some years without gapps.

sasvarion Why I deleted my Facebook account

  Are people nowadays not capable of moderation? Purely
  anecdotally, but I mostly see older generations being the
  ones that hop off. Is it because they didn’t grow up with
  this kinda of social media and can’t seem to balance what
  is a perfectly fine way to interact with friends and stay
  updated without pulling a cold turkey on it?

95% of the people I see on the subway every day are glued to their smartphones without interruption the moment they enter the carriage until they leave. And around 80% of the time I get a glimpse of the screen of those it's facebook/instagram/snapchat/<insert your social network of choice>. This is somehow independent of age. So moderation? Balance? Probably depends on the definition.

sasvarion Why I deleted my Facebook account

  If you were a regular user since 2005 and leave now, it does not make any
  difference anymore. The collected data about you is enough to interpolate
  your profile for the next decades.

Does it really matter if you have been on facebook at all? Even if you never joined, people upload their addressbooks with all of their contacts, they upload pictures of people never been on facebook and tag them (and share other information about everyone, which facebook probably is able to use as well). So essentially facebook builds your social graph no matter if you have ever been a member or not.

It does make a difference. Just not to care and to give up is no solution either.

sasvarion What fossil fuels are doing to our oceans

in a 1:1 substitution case. but locally, sustainably (yeah, maybe not the right word ... organically?) produced meat is more expensive, which should lead people to eat less meat, but if they eat meat to consume meat produced locally with a smaller environmental footprint (if that's the case, I'm not an expert in that field).

maybe that's just wishful thinking though.

sasvarion What fossil fuels are doing to our oceans

While I applaud your meat buying preferences, it would be an environmental disaster for every meat eater on earth to attempt to do the same.

I might not get the point, but why would it be a bigger environmental disaster?
