What does "loop on itself" mean in this context? The article repeats it 5 times but I can't find a thesaurus definition, and it's unclear to me if the author means it as a synonym repeat or *self-amplify or something different.

The author is perhaps presenting a good argument for languages/runtimes like JavaScript/Node where dependencies may be isolated and conflicting dependencies may coexist in the dependency tree (e.g., "app -> { libpupa 1.2.3 -> liblupa 0.7.8 }, { libxyz 2.0 -> liblupa 2.4.5 }" would be fine), but the proposed dependency resolution algorithm...
> Our dependency resolution algorithm thus is like this:
> 1. Get the top-level dependency versions
> 2. Look up versions of libraries they depend on
> 3. Look up versions of libraries they depend on
...would fail in languages like Python where dependencies are shared, and the steps 2, 3, etc. would result in conflicting versions.
In these languages, there is good reason to define dependencies in a relaxed way (with constraints that exclude known-bad versions; but without pins to any specific known-to-work version and without constraining only to existing known-good versions) at first. This way dependency resolution always involves some sort of constraint solving (with indeterminate results due to the constraints being open-ended), but then for the sake of reproducibility the result of the constraint solving process may be used as a lockfile. In the Python world this is only done in the final application (the final environment running the code, this may be the test suite in for a pure library) and the pins in the lock aren't published for anyone to reuse.
To reiterate, the originally proposed algorithm doesn't work for languages with shared dependencies. Using version constraints and then lockfiles as a two-layer solution is a common and reasonable way of resolving the dependency topic in these languages.
Why would "0^5" evaluate to 5? (question 21)
And is there a way to link to a specific question?
^ is the XOR operator, 0 XOR 5 is 5. (Exponentiation is *)

If they have enough users/make enough money, they'll make their own. Ecosia and Qwant (both european search engines) are working together to make their own index.
In any case, even if a european is a proxy for an american service, you need to prove that there is a market for an european equivalent for change to happen.

palotasb commented on C "clockwise/spiral" rule to understand declarations c-faq.com/decl/spiral.and... · Posted by u/galkk
The spiral rule works only if there is no pointer to pointer or array of array in the type. In other words it is an incorrect rule. But take this for example:
+----------------------------+
| +-----------------------+ |
| | +------------------+ | |
| | | +-------------+ | | |
| | | | +--------+ | | | |
| | | | | +--+ | | | | |
| | | | | ^ | | | | | |
int * * ¦ ¦ ¦ VAR[1][2][3] | | |
^ | | | | | | | | | | |
| | | | | +-----+ | | | | |
| | | | +----------+ | | | |
| | | +---------------+ | | |
| | ---------------------+ | |
| +-------------------------+ |
+-------------------------------+
The Right-Left Rule is quoted less frequently on HN but it's a correct algorithm for deciphering C types: http://cseweb.ucsd.edu/~ricko/rt_lt.rule.html
The spiral rule can be modified to process all array specifiers before all pointer specifiers, but then you'd have to specify that the order to do so is right and then left. At that point it's just the Right-Left Rule.
That's not going to happen.
Remember when the EU wanted to build it's own internet browser? Or it's own search engine? Or it's own sovereign cloud?
None of these initiatives panned out. This is just political posturing when they have literally zero plans on how to achieve that.
But https://en.wikipedia.org/wiki/Galileo_(satellite_navigation) panned out and that's a closer analogue.

Can someone explain this, the italicized part below, in more detail?
>> When you approach from the side street, as a driver, the order of dealing with other traffic is different, but the priority is similar. First you will notice a speed bump. The complete intersection is on a raised table. Pedestrians would not have priority if the street was level, but now that it isn’t the “exit construction” rule could apply and in that case a crossing pedestrian would have priority. But for that rule to apply the footway should be continuous, and that is not the case here.
https://www.theorieexamen.nl/theory-exam/what-is-a-entrance-...
An entrance or exit construction is a place on a road where you aren't just turning onto the road but exiting the road entirely. The most common example from any country would be a private driveway. Pedestrians, cyclists and cars going along the sidewalk, bike path or road have priority against anyone turning into the driveway or turning onto the road from the driveway.
The Netherlands generalizes this concept to some low-priority side streets. If there is a continuous sidewalk (i.e., the cars go up a bump to the level of the sidewalk as opposed to the pedestrians stepping down from the sidewalk to the level of the street). This is not the case in this specific intersection.

> Here you can see that a car drivers waiting for people cycling are never in the way of other people in cars.
Am I blind or does it only work for just one or maybe two cars?
Correct, only one.
This specific turn is onto a street that the article describes as "traffic volume here is low, since only residents will use this street." They probably expect the 1-car buffer to be enough for this intersection. You can see in the video that the 1-car buffer is empty most of the time.
For intersections where they expect more turning traffic (where the one car buffer wouldn't be enough), they add turning lanes that can accomodate more than one car. You can see an example of this a few hundred meters northeast when Graafseweg intersects the Van Grobbendocklaan: https://maps.app.goo.gl/ZmURqawr3oeBX5Sq9

I'm probably dumb, but why would that be proof?
I upload encrypted backups to a cloud service provider (AWS, Google Cloud). I go to another computer, download them, use a key/password to decrypt them.
Sure, I get it, you're typing in something that decrypts the data into their app. That's true of all apps including WhatsApp, etc... The only way this could really be secure is if you used a different app to the encryption that you wrote/audited such that the messaging app never has access to your password/private key. Otherwise, at some point, you're trusting their app to do what they claim.
> > using the password recovery flow
> use a key/password
The previous poster intentionally mentioned password recovery flow. If you can gain access without your password, than law enforcement can too. If you could only gain access with your password, you could consider your data safe.
