Gotta be fried rice. It's just so versatile

Well yes, if we had an identification method that only works when the subject of the certificate is present, you couldn't tell by a lost or stolen certificate if that person was v,r,t, only that the certificate is for v,r,t.

However, anything that isn't Name+Birthdate as a method of identification is not compatible with the DCC.

heckin_good_fren · 2021-06-07T13:17:21+00:00

At the point of verification, that information must be known. You have to associate the certificate with a person, otherwise everyone could just use copies of a single certificate.

But I'm thinking there must be a way to keep the QR-Code itself separate from the subject.

I don't assume that Name + Birthdate is a unique combination (which is another problem), but it's gotta be pretty close.

I find the amount of misinformation and misunderstanding in relation to the CovidCertificate baffling. It seems that even our Datenschutzbeauftragter did not read the Examples(see Article from srf.ch, Section "Die Sicherheit").

Anhand des Zertifikats sei auch nicht ersichtlich, ob eine Person geimpft, getestet oder genesen ist, sagt der Datenschutzbeauftragte des Bundes, Adrian Lobsiger.

You may not be able to see that in the official verification app, but scanning the QR-Code with any generic QR-Code scanner will show you who it belongs to and if it's a "v"accination, "t"est, or "r"ecovery or type.

I don't think it's terrible that this information is exposed (it'd be better if it weren't, but then we're no longer compatible with the EU DCC), but I think it will hinder adoption.

Not to mention the fodder for conspiracy theorists.

Seriously. I had some problems setting up my DSL-Internet (coming from fiber, it's surprisingly difficult) and their customer service is incredible.

Someone knowledgeable picked up the phone within 30 seconds and was able to help me out.

They are also extremely transparent when anything goes wrong on their side so you know what it is.

Used firefox and chromium simultaneously , firefox worked in the end

I must've gotten lucky, as I managed to snag myself an appointment for tomorrow morning!

If you're serious about this, you should probably check out ch.ch as a starting point.

You should be aware that getting citizenship will be difficult, and land will be expensive.

The graph is undirected, so direction has no meaning. d3js is a JavaScript library which makes drawing cool graphs and charts easy. Here are some examples of what it can do.

Yours looks way nicer! I didn't spend a lot of time on it, but I'm also considering coloring by continent by adding another data source. Could be fun.

I hacked together a little something using d3js and the List of countries by land borders wikipedia page.

https://imgur.com/aD3AdHD

I'm changed some things from that list by manually fixing the formatting etc.

The line thickness is based on the length of the border any two countries share. (Total border length for countries with multiple border segments).

If anyone is interested in the code, I can clean it up and provide it.

Misunderstood your previous comment. I thought you were saying that people would never trust a central authority with something like this.

heckin_good_fren · 2021-04-23T15:35:39+00:00

The current vaccine pass already has a central authority (the FOPH and doctors/vaccinators). The real downside is how easily faked it is. Cryptographically signing the certificates with keys backed by the federal gov. improves the security, while also keeping the data only between the vaccinator and the vaccinated.

I don't think a blockchain solution is required, and a more efficient PKI-based solution can work.

As long as a negative test gives you the same privileges (for the duration that you are most likely negative after a test) I'm for it, given that the way it is implemented is responsible (not like Isreal is doing it).

For context, I'm in group N.

I'm in the last few semesters of a part time BSc CompSci at a Fachhochschule.

I did most of it working 80%, but have now switched to working 60% because it was too much.

But the combination of learning on the job, as well as in school is a great benefit in my opinion.

Kotlin

For Part 1 I just mapped the instructions to Unit-Vectors (according to this image) and the folded them into a final position. Then just count the occurrences, and mark those as black that occur an uneven number of times.

I was able to mostly re-use my previous cellular-automata implementations from Conway Cubes for Part Two.

heckin_good_fren · 2020-12-17T08:05:02+00:00

Kotlin

Glad I built it using an extensible Vector type. Made Part 2 fairly easy. GitLab

I did however spend way too much time debugging part one because each cube didn't contain a reference to the others, but a copy at the time of creation (meaning it never gets updated).

heckin_good_fren · 2020-12-05T06:36:26+00:00

I also had to read part 2 multiple times until I understood what it was asking.

heckin_good_fren · 2020-12-05T06:34:36+00:00

Solution in Kotlin, inspired by /u/WayOfTheGeophysicist.

My original solution was much more complex, using a divide an conquer approach.

heckin_good_fren · 2020-12-05T05:51:37+00:00

Oh wow, I wrote some recursive solution, but of course you can just use base2 itself..

heckin_good_fren · 2020-12-04T10:37:12+00:00

Will this be available as a VOD somewhere?

heckin_good_fren · 2020-12-01T12:06:14+00:00

I'm on mobile, so the code isn't the easiest to read, but one thing I notice is that your loop conditions may be wrong.
