pYQAJ6Zm··on Wind and solar power are disrupting electricity systems
It’s a red flag. It’s useful.
pYQAJ6Zm··on Ask HN: What's your backup setup?
I rely mostly on Borg backup¹.

1. First, I run it locally on my desktop against a repository I keep on the same drive (/home/backup); then

2. I update, with rsync, a copy of this repository I keep on a dedicated server with full disk encryption; and, finally,

3. I spin up an EC2 instance, mount an S3 bucket with s3ql, and rsync the copy from the previous step up to the one I keep on this bucket.

This process is (embarrassingly) manual.

The backup repository is encrypted with Borg itself, and if I am in need of recovering something I do it from the local copy. I never mount the repository in remote locations.

pYQAJ6Zm··on Mark Zuckerberg's manifesto for Facebook offers a social dystopia
I agree; it’s a terrible name for it. I also googled it and found a website whose lead image is a hangman’s noose – seriously, come on. Let’s call it online identity liberation, retaking, protection, or whatever.
pYQAJ6Zm··on StrongSwan – IPsec VPN for Linux, Android, FreeBSD, Mac OS X, Windows
During the past holidays, at my parent’s, I set up some infrastructure to allow remote management of some network equipment and computers. I used to employ OpenVPN for this, but I decided to give IPsec a try. Since I have been learning CentOS, initially I went with RedHat’s suggested option: Libreswan.

I tried and tried, yet couldn’t get it to work. Documentation surely was lacking for Libreswan. But then I found Strongswan, and after a few more attempts I managed to set a tunnel as I wanted it. The documentation is much more complete, and the examples were specially helpful.

I am baffled by the choice made by RedHat, to use Libreswan as their official IPsec implementation. It gave me a “beta” feel, while Strongswan seems more solid. Plus the difference regarding documentation is like night and day.

pYQAJ6Zm··on AMD Ryzen Full Lineup Prices, Specs and Clock Speeds Leaked
>Now you can't use the GPU anymore, the module was assigned by KVM and you can't - for instance - run a CUDA simulation in the Linux host.

Maybe we had different setups, so this wouldn’t apply – I used to unbind the device with the following script, and then load the `nvidia` module; the device was then available on the host:

  for dev in "0000:01:00.0" "0000:01:00.1"; do
          if [ -e /sys/bus/pci/devices/${dev}/driver ]; then
                  echo "${dev}" > /sys/bus/pci/devices/${dev}/driver/unbind
          fi
  done
pYQAJ6Zm··on AMD Ryzen Full Lineup Prices, Specs and Clock Speeds Leaked
One reason is to mix AMD and NVIDIA GPUs – I experimented with running X on the integrated Radeon device, while running CUDA on a Linux guest with GPU-passthrough. Trying to have CUDA on the host system led to library conflicts.
pYQAJ6Zm··on Four Kinds of Dystopia
>The most obviously missed type would appear to be dystopians characterised by extreme disparities between rich and poor, where the dystopic regime is generally so much better off than the underclass it doesn't need to bother with enforcing or influencing worldviews beyond basic security measures (much of cyberpunk, for example).

The Brazilian TV series 3% is I think worth of mention, as it fits very well in this space.

pYQAJ6Zm··on Designing a Business Card in LaTeX
I ditched GA after I tried Authy. Built-in QR scanner, plus syncing with non-mobile devices.
pYQAJ6Zm··on How to Unlock Netflix Hidden Categories
I am able to go full-screen by pressing ‘f’, using Chrome on Linux.
pYQAJ6Zm··on About Those Air Cushions in Amazon Packages
Share them with neighbors maybe, should they need to ship something?
pYQAJ6Zm··on About Those Air Cushions in Amazon Packages
I was pleasantly surprised when I got my first Now purchase delivered that way. I was expecting a box. But the paper bag is better -- I use them as “garbage bags” for paper and cardboard, which makes the recycling quicker on my end.
pYQAJ6Zm··on Uber’s self-driving cars start picking up passengers in San Francisco
Maybe this would self-regulate. If someone is the kind of person that would make a mess on an autonomous car ride, maybe after calling the service again and having to wait for a replacement due to someone else’s carelessness, their attitude would change.
pYQAJ6Zm··on Reflecting on the Right to be Forgotten
IANAL, but, for comparison, in Spain the right to privacy may be superseded if there are good reasons of public interest. For example, the daily stories of the average Joe’s life are covered by the right to privacy, but the same details for a major politician might be not, in the proper circumstances. It’s not always a black and white issue, but something to be decided at court.

Regarding the article, I’m not familiar enough with the "Right to be Forgotten" directive to question the choosing of the examples opening the text, but to me it seems biased. These examples are arguably the kind of information which couldn’t be legally hidden because of public interest.

pYQAJ6Zm··on Worried About the Privacy of Your Messages? Download Signal
Perhaps in the future an authoritarian government will single you out, together with others, for being politically “neutral” and thus fit for taking part in some kind of “neutral” policy enforcement corps.

Rare possibility? Yes. But it’s a possibility. «Nothing to hide, nothing to fear» arguments cannot stand before this sort of scrutiny.

pYQAJ6Zm··on Azure Jupyter Notebooks
I suggest having a look at the jupyter-vim-binding¹ extension. It improves the experience for those comfortable with Vim.

pYQAJ6Zm··on Bitcoin Beat the Trough of Sorrow
Just for the record, transfers within the SEPA zone cost me nothing in fees with either of my two banks.
pYQAJ6Zm··on Everyone who can now see your entire internet history, including the taxman
I suggest AirVPN (no affiliation). I’ve been using it for more than a year, and it’s reliable, with plenty of servers and good speeds. If I am not mistaken, it’s operated from Italy.

Another option is to rent a VPS/dedicated server somewhere outside the UK, with decent bandwidth and data cap, and configure your own VPN between your systems, using the rented server as the internet gateway.

pYQAJ6Zm··on Quorum – JP Morgan’s permissioned implementation of Ethereum
The way I recall it, they didn’t void past transactions; they added “irregular state changes” that would “return” the “stolen” funds to their “legitimate“ owners. Nor were they forced to fork; it was a voluntary decision of a group of people with enough social power over the platform.

Now this is more a matter of dispute, but I wouldn’t say the hacker stole the funds. They simply followed the DAO contract (not the “smart-contract”, mind you, but the one put forward by the Slock.it team on their page), according to which everything that went on the blockchain according to the DAO code was legitimate.

pYQAJ6Zm··on MacOS 10.12 Open Source Components
I really like the idea. Where free licenses are concerned, I believe this would help “cross-pollination” among projects and facilitate the progress of open source.

It could also work as a (perhaps curated) reference. Sort of like Rosetta Code, but for more high-level features ­– “how have projects X and Y chosen to implement this feature?”

Besides, it could serve an archival function. A quick search on the web reveals a couple of projects on this vein, but they tend to rely on storing official releases. The way I see your idea, it could be made to work in a way closer to what archive.org does for the web, archiving everything it’s permissible to, with the addition of meta information about the projects, their relationships, etc.

Not a small undertaking, but a very inspiring one!

pYQAJ6Zm··on Bye Bye Emojis: Emacs Hates MacOS
If you discover Emacs on macOS, and like among other things the multicolor feature, then decide to try the Full GNU Experience™ and find that that feature is not supported on the flagship (!) GNU product, well, then maybe you’ll be back to macOS after all.

Let’s not forget that thanks to its libre licensing this is a strategic issue, but not a technical one – recovering the removed features on macOS is a few patches away.

pYQAJ6Zm··on Stoicism: Indifference is a power
This is thoroughly encyclopedic, so not concise as you ask for, but it may nevertheless interest you: http://plato.stanford.edu/entries/stoicism/
pYQAJ6Zm··on The mathematics of science’s broken reward system
Noting that epistemology is concerned with the study of (the concept of) knowledge, and may (in principle) go beyond what’s involved in the purely scientific acquisition of such (if some non-scientific method for the acquisition of knowledge is to be accepted).

“Philosophy of science,” already mentioned, is probably a better fit. Once you go meta on science, after all, you are (arguably) not doing science anymore, so there is no harm in naming it a kind of philosophy.

pYQAJ6Zm··on Hierarchical Object Detection with Deep Reinforcement Learning
That is helpful, thank you.

But the most concerning issue however, in my opinion, and taking into account the amount of attention that the NTM paper got, is that (to my knowledge) all public implementations of the suggested architecture involve a great deal of guesswork. The researchers didn’t release any code; only vague details about the architecture and results that we must take on their word. The note they released is, I think, closer to being a tantalizing press release than a proper scientific report.

pYQAJ6Zm··on HP Unveils Mini Workstation
So, for let’s say 1 TB, if my calculations follow this correctly, that would be between ~6 and ~10 SEU/h.

I am worried about my personal backups now.

pYQAJ6Zm··on Post Virtual Reality Sadness
>I can comfortably work in VR with multiple desktops, but the resolution is tad too low.

I am interested in this. Can you, say, write code or read text for long hours, without having to upsize the text too much?

pYQAJ6Zm··on Hierarchical Object Detection with Deep Reinforcement Learning
And in a manner of contrast, Google DeepMind’s “Neural Turing Machines” still gives me nightmares. Where are the implementation details, where?! A perfect example of how science should _not_ be reported.
pYQAJ6Zm··on Blacknurse – Low bandwidth ICMP firewall attack
I haven’t thought of the term in that sense until reading your post. Not because I am unaware of black issues, but because I’m not an American and my context simply lacks the implied connotation for the term in question.

The political correction you ask for is USA-centric. I don’t know if the people behind blacknurse.dk are American, but, if the domain is an indication, they may not be.

pYQAJ6Zm··on FBI operated 23 Tor-hidden child porn sites, deployed malware from them
Not quite. Perhaps a consumer of pornography consumes only what they already like. Personally, watching, say, bondage out of curiosity didn’t make me like the stuff.
pYQAJ6Zm··on Show HN: Taste Movies – Watch movies based on your taste
I submitted few ratings, and yet I got a lot of very spot-on recommendations – movies that I’ve seen and much enjoyed. The UI is also very clear and pretty.

This is very well done. Profile created!

pYQAJ6Zm··on Apple's Great GPL Purge (2014)
Re: compilers; as I understand it, using a GPL compiler doesn’t extend its license unto the produced binaries. Those vendors could be using GCC instead, and still contribute to its development without danger of jeopardizing their intellectual property.
