For each output declared in outputs, the corresponding environment variable is set to point to the intended path in the Nix store for that output. Each output path is a concatenation of the cryptographic hash of all build inputs, the name attribute and the output name. (The output name is omitted if it’s out.)
QUESTION: So when I see
$out
in a builder script, it refers to the default output path because theoutput
attribute in the Nix expression has never been explicitly set, right? -
derivationA description of a build action. The result of a derivation is a store object. Derivations are typically specified in Nix expressions using the derivation primitive. These are translated into low-level store derivations (implicitly by nix-env and nix-build, or explicitly by nix-instantiate).
Organically related to the annotation regarding my
nix-shell
confusion.The dissection of this definition to show why I find it lacking:
A description of a build action.
The first (couple) time(s) I read the manuals, this description popped up in many places, and I identified it with Nix expression every time, thinking that a derivation is a synonym for Nix expression.
Maybe it is, because it clearly tries to disambiguate between store derivations and derivation in the last sentence.
The result of a derivation is a store object.
Is this store object the same as a store derivation?
Derivations are typically specified in Nix expressions using the `derivation primitive. These are translated into low-level store derivations (implicitly by nix-env and nix-build, or explicitly by nix-instantiate).
QUESTION: So, the part of the Nix build expression (such as
default.nix
) where thederivation
primitive is called (explicitly or implicitly, as inmkDerivation
) is the derivation, that will be ultimately be translated into store derivations?ANSWER: Start at section 15.4 Derivation.
QUESTION: Also, why is typically used here? Can one define derivations outside of Nix expressions?
ANSWER(?): One could I guess, because store derivations are ATerms (see annotation at the top), and the Nix expression language is just a tool to translate parameterized build actions into concrete terms to build a software package. The store derivations could be achieved using different means; e.g., the way Guix uses Guile scheme to get the same result))
I believe, that originally, derivation was simply a synonym to store derivation. Maybe it still is, and I'm just having difficulties with reading comprehension but I think the following would be less misleading (to me and apart from re-writing the very first sentence):
Derivations are typically the result of Nix expressions calling the
derivation primitive explicitly, or implicitly using
mkDerivation`. These are translated into low-level store derivations (implicitly by nix-env and nix-build, or explicitly by nix-instantiate). -
$stdenv/setup
QUESTION: Does this refer to
pkgs/stdenv/generic/setup.sh
? According to 6.5 Phases in the Nixpkgs manual?ANSWER: I'm pretty sure it does. It sets up the environment (not sure how yet; I see the env vars, but not the basic commands - sed, awk, etc. - that are listed below) and defines a bunch of functions (such as
genericBuilder
) but it doesn't call these functions! -
substitute
this is another key topic. Also:
- substitute vs. substituter => this (I think)
See annotations with the
substitute
tag -
When you ask Nix to install a package, it will first try to get it in pre-compiled form from a binary cache. By default, Nix will use the binary cache https://cache.nixos.org; it contains binaries for most packages in Nixpkgs. Only if no binary is available in the binary cache, Nix will build the package from source. So if nix-env -i subversion results in Nix building stuff from source, then either the package is not built for your platform by the Nixpkgs build servers, or your version of Nixpkgs is too old or too new.
binary caches tie in with substitutes somehow; get to the bottom of it. See annotations with the
substitute
tag.Maybe this?

At the same time, it is not possible for one user to inject a Trojan horse into a package that might be used by another user.
Why?
Answer is below in the manual: https://hyp.is/qRSFdnCJEeueY8NWtMIeHw/toraritte.github.io/saves/Nix-Package-Manager-Guide-Version-2.3.10.html
-
Chapter 6. SecurityNix has two basic security models. First, it can be used in “single-user mode”, which is similar to what most other package management tools do: there is a single user (typically root) who performs all package management operations. All other users can then use the installed packages, but they cannot perform package management operations themselves.Alternatively, you can configure Nix in “multi-user mode”. In this model, all users can perform package management operations — for instance, every user can install software without requiring root privileges. Nix ensures that this is secure. For instance, it’s not possible for one user to overwrite a package used by another user with a Trojan horse.
Would have been nice to link these to the install chapter where single- and multi-user modes were mentioned.
How would this look in a topic-based documentation? I would think that his chapter would be listed in the pre-requisites, and it could be used to buld different reading paths (or assemblies in DocBook, I believe) such as
practical
,depth-first
(if there are people like me who want to understand everything first), etc. -

nix-shell '<nixpkgs>' -A pan
What is happening here exactly?
nix-shell
's syntax synopsis always bugged because it looks like thisSYNOPSIS nix-shell [--arg name value] [--argstr name value] [{--attr | -A} attrPath] [--command cmd] [--run cmd] [--exclude regexp] [--pure] [--keep name] {{--packages | -p} packages... | [path]}
and the canonical example is
nix-shell '<nixpkgs>' -A pan
; what tripped me up is thatpath
is usually the first in examples, and I thought that the position of arguments are strict. As it turns out,nix-shell -A pan '<nixpkgs>
is just as valid.Side note<br> Apparently there is no standard for man pages. See 1, 2.
'<nixpkgs>'
path is the one specified in theNIX_PATH
environment variable, and-A pan
looks up thepan
attribute inpkgs/top-level/all-packages.nix

17.3. Fixed point
QUESTION: What is a fixed-point of a function?
ANSWER: See this video) at least, and the Fixed-point (mathematics)) wikipedia article:
In mathematics, a fixed point (sometimes shortened to fixpoint, also known as an invariant point) of a function is an element of the function's domain that is mapped to itself by the function. That is to say, c is a fixed point of the function
f
iff(c) = c
. This meansf(f(...f(c)...)) = f n(c) = c
an important terminating consideration when recursively computing f. A set of fixed points is sometimes called a fixed set.
For example, if f is defined on the real numbers by
f(x)=x^{2}-3x+4,}
, then 2 is a fixed point off
, becausef(2) = 2
.There is also the wiki article fixed-point combinator that actually plays a role here, but read through the articles in this order.
Then dissect the Stackoverflow thread What is a Y combinator?, and pay attention to the comments! For example:
According to Mike Vanier's description, your definition for Y is actually not a combinator because it's recursive. Under "Eliminating (most) explicit recursion (lazy version)" he has the lazy scheme equivalent of your C# code but explains in point 2: "It is not a combinator, because the Y in the body of the definition is a free variable which is only bound once the definition is complete..." I think the cool thing about Y-combinators is that they produce recursion by evaluating the fixed-point of a function. In this way, they don't need explicit recursion. – GrantJ Jul 18 '11 at 0:02

Derivations/packages are stored in the Nix store as follows: /nix/store/hash-name, where the hash uniquely identifies the derivation (this isn't quite true, it's a little more complex), and the name is the name of the derivation.
QUESTION: So the Nix store houses derivations and not the built packages?
QUESTION: Are the hashes in the Nix store not unique?

What is the opposite of free content?
The opposite of free/open-source software is proprietary software or non-free software (https://en.wikipedia.org/wiki/Proprietary_software).
So should we call the opposite of free content "non-free content"? Or "proprietary content"?
Seems likes either would be fine.
Looks like https://en.wikipedia.org/wiki/Wikipedia:Non-free_content prefers the term "non-free content".
Couldn't find anyone contrasting these 2 terms (like I could no doubt find for software):
- https://duckduckgo.com/?q=+%22non-free+content%22+%22free+content%22
- https://duckduckgo.com/?q=%22proprietary+content%22+%22free+content%22&ia=web
Not to be confused with:
- paid content ... just like:
- free content should not be confused with gratis content (?)
- free software should not be confused with freeware

However, using channels is not fully reproducible, as a channel may evolve to incorporate updates.
TODO: Find other sources about this topic. I remember this mentioned already (and it makes) sense, but need to learn more.
TODO: What is a better alternative? An own repo? Flakes? Can cachix help?
It says right below that pinning can help but keep looking.
When package reproducibility become a major concern, as it is the case in this tutorial, it is preferable to refer to a pinned version of the nixpkgs repository instead — i.e, a specific commit of the repository or an immutable archived tarball. The ability to pin the version of nixpkgs is powerful, it will ensure that a package is always constructed from the same Nix source. As we go deeper in the tutorial we avoid using channels in favor of pinned environments.

If the Klensin Standards Track [Page 19] RFC 5321 SMTP October 2008 recipient is known not to be a deliverable address, the SMTP server returns a 550 reply, typically with a string such as "no such user - " and the mailbox name (other circumstances and reply codes are possible).
Will the entire transaction be canceled? "Transaction" in the name of this a section implies yes, but what if all the recipients are valid?
See replies below but the answer is no; an
RCPT
command is specified for each recipient in the mail data, theseRCPT
commands will be evaluated in sequence,, and any SMTP (error) notifications will be sent to the address in theMAIL FROM
command (which is not necessarily the same as the mail data'sFrom:
header). -
If the verb is initially accepted and the 354 reply issued, the DATA command should fail only if the mail transaction was incomplete (for example, no recipients),
How could this specific scenario be even possible? It just said in the previous paragraph that
If there was no MAIL, or no RCPT, command, or all such commands were rejected, the server MAY return a "command out of sequence" (503) or "no valid recipients" (554) reply in response to the DATA command.

In this context, the objective of thisstudy is to increase knowledge of the motivations and patterns of behaviour of foodstagrammertourists and to contribute new insights about this phenomenon. In the first part of the article,therefore, we establish the framework for the characteristics and motivations of foodstagrammertourists. We then describe the ethnographic methodology employed in this study and presentour detailed fieldwork. Finally, we explain our findings and discuss the phenomenon of foodsta-grammer tourists and their managerial implications.
The research study, 'An Ethnographic Study of Motivations of Foodstagrammer tourists' highlights how a research question may be portrayed by using a broad research statement to identify their overarching focus of inquiry as opposed to directly stating a research question. In this study, it is found in the goals of the study and could be converted to a question format. Stating the purpose for the inquiry works as effectively as proposing a prompt research question.

Without such limits on derogatory, racist, sexist, or homophobic materials, Google al-lows its algorithm—which is, as we can see, laden with what Diaz calls “sociopolitics”—to stand without debate while protesting its inability to remove pages.
Why does google straight allow terrible thing to be presented and will only remove unlawful content? Hopefully if you search some of these words that show explicit things that they warn some people may feel disgusted or get offended. Most of the information is also incorrect so they are providing false things

Man, for some reason, I really like this answer. I recognize it's a bit more complicated, but it seems so useful. And given that I'm no bash expert, it leads me to believe that my logic is faulty, and there's something wrong with this methodology, otherwise, I feel others would have given it more praise. So, what's the problem with this function? Is there anything I should be looking out for here?
I think the main thing wrong with it is the eval (which I think can be changed to
$("$@")
and it's pretty verbose.Also, there are more concise ways to do it that would probably appeal more to most bash experts...
like set -x
and it does unnecessary things: why save output to a variable? Just let output go to where it would normally go...
So yeah, I can see why this solution isn't very popular. And I'm rather surprised by all the praise comments it's gotten.

is there a way we can specify for image build layers to be included in the pull?

Sorry, I don't totally know how the internals work, but does there currently exist a workaround? By that I mean, can I pull an image, then run it at a layer other than the top layer? (I basically use this for testing purposes, its certainly possible to build the image myself then do it, but its slightly less convenient)

I really dont need a solution to this problem! I can find many workararounds
Actually, the answer that was given was a good answer, as it pointed to the problem: It was a reminder that you need to:
assign to a locally declared variable.
So I'm not sure the answer was intended to "just" be a solution/workaround, but to help correct or fill in the misunderstanding / forgotten piece of the puzzle to help OP realize why it wasn't working, and realize how reactivity is designed to work (based on assignments).
It was a very simplified answer, but it was meant to point in the right direction.
Indeed, it pointed to this main point that was explained in more detail by @rixo later:

Steele has noted that stereotype threat is most likely in areas of performance in which individuals are particularly motivated
Stereotype threat is an important factor in student performance that faculty should be aware of, particularly with marginalized students and adult learners who may not identify as successful students, but how does it affect their own performance as instructors? If they care about teaching, but don't identify primarily as instructors, does this limit their teaching ability?

Normal aging is accompanied by a gradual decline in episodic memory that begins as early as the twenties and accelerates precipi-tously after the age of 60 (Salthouse, 2009). This decline is associated with degradation in a key aspect of episodic memory: the ability to anchor or bind an event to one’s personal past and to a location (e.g., Fandakova et al., 2014; Wheeler et al., 1997).
Is this contrary to what they said above about adults remembering more aspects of episodes? How does this decline in episodic memory affect learning in adults?

Could you please explain why it is a vulnerability for an attacker to know the user names on a system? Currently External Identity Providers are wildly popular, meaning that user names are personal emails.My amazon account is my email address, my Azure account is my email address and both sites manage highly valuable information that could take a whole company out of business... and yet, they show no concern on hiding user names...
Good question: Why do the big players like Azure not seem to worry? Microsoft, Amazon, Google, etc. too probably. In fact, any email provider. So once someone knows your email address, you are (more) vulnerable to someone trying to hack your account. Makes me wonder if the severity of this problem is overrated.
Irony: He (using his full real name) posts:
- Information about which account ("my Azure account is my email address"), and
- How high-value of a target he would be ("both sites manage highly valuable information that could take a whole company out of business...")
thus making himself more of a target. (I hope he does not get targetted though.)

He took three paces—with the fourth he reached his goal,
Interesting depiction of the actual size of gods here. If Poseidon was this large, how large would other gods appear such as Zeus? Or even Cronus, as literature suggests he too has a physical form. Would gods be able to show their true form to humans? Or is this why Zeus often appears as other beings when interacting with mortals.

Another example:
const expensiveOperation = async (value) => { // return Promise.resolve(value) // console.log('value:', value) await sleep(1000) console.log('expensiveOperation: value:', value, 'finished') return value } var expensiveOperationDebounce = debounce(expensiveOperation, 100); // for (let num of [1, 2]) { // expensiveOperationDebounce(num).then(value => { // console.log(value) // }) // } (async () => { await sleep(0 ); console.log(await expensiveOperationDebounce(1)) })(); (async () => { await sleep(200 ); console.log(await expensiveOperationDebounce(2)) })(); (async () => { await sleep(1300); console.log(await expensiveOperationDebounce(3)) })(); // setTimeout(async () => { // console.log(await expensiveOperationDebounce(3)) // }, 1300)
Outputs: 1, 2, 3
Why, if I change it to:
(async () => { await sleep(0 ); console.log(await expensiveOperationDebounce(1)) })(); (async () => { await sleep(200 ); console.log(await expensiveOperationDebounce(2)) })(); (async () => { await sleep(1100); console.log(await expensiveOperationDebounce(3)) })();
Does it only output 2, 3?

so there is no signi cant correlation be-302tween Fram Strait sea ice drift and AO/DA indices
Smedsrud et al. (2017) point to the fact that the AO - Fram Strait export correlation is non-stationary in time. The results presented here are in line with what Smedsrud et al. report for the 21st century. Yet, I am curious about the earlier period, do you see any correlation between drift and AO in earlier periods of the FESOM simulations?
-
Relative contributions from winds and thermal forcing
I find this section very convincing!
One additional suggestion, still. What do the sea ice area export curves look like in the FESOM simulations? I am assuming that if you were to look at area export (function of ice drift and ice concentration), you would get a similar picture to Fig. 3c - i.e.: slightly positive trends, with the variability almost entirely explained by winds. Is it possible to show that (additional panel in Fig. 3)? I believe it would bring yet an another argument supporting that the long term trend in volume export has to be thickness driven.

he same as(a) but for sea ice thickness.

blazes
This word is ambiguous. It has several meanings. This is what poet thinking is all about for me--subverting the routine. First, the word is about fire, right, but if you have every looked at my posts (count on two hands my very fine viewership) you know that I write about trail blazes. I want the word to be a fork and to mean both of these simultaneously. My poems are designed to carry a lot of freight. What do you think about ambiguity?
-
ethical blazes
What ethical blazes have books kindled in you? Most poetry tries to freshen the language. Most poets are work necromancers. They bring what is routine and everyday back into clear and plain air. This is called a metaphor. Values don't really burn, but I am trying to conjure up a feeling here where what we believes has the intensity of a fire. I am trying to do that with a few words and not a lot like here. Maybe poetry is all about translation and summary put together. What do you think poetry is supposed to be or do?

Actually just returning the loginDaoCall works fine. I dont really get what's different as it is the looked like it was the same instance, but probably not.
So the posted answer wasn't necessary/correct? Which part of the answer was incorrect/unneeded?
I wish this OP comment included the full version of code that worked.
I don't understand this OP comment. Wasn't OP already returning
loginDaoCall
? So maybe the only thing they could mean is that they just needed to change it toreturn loginDaoCall.then(...)
instead...That would be consistent with what the answer said:
the promise returned by the further .then() does also get rejected and was not handled.
So I guess the unnecessary part of the answer was adding the
return true
/false...

Now long-haired Achaeans are mocking us, saying we’ve put forward as a champion one who looks good, but lacks a strong brave mind.
Why do you think when the Trojans are mentioning the Greeks they mention them as "long-haired Achaeans"?
My take on it is that its an insult as to call them out to look like women because they have long hair as Homer does include insults that relate to the opposite sex.

Despicable Paris, handsomest of men, but woman-mad seducer. How I wish you never had been born or died unmarried.
Why do you think the statement of "handsomest of men" was used by Homer when it is stated that Hector is insulting him?
In my opinion, he is trying to create a reflection of how he looks the part of a hero but, lacks the internal motivations to be a real hero.

Can this word be used to describe the property in computing where a value can be dynamic? I feel like "dynamicness" would be a better term for this.

Part of the reason is there’s a slight lag. No matter how good your internet is, no matter how fast it is, it seems we have this millisecond—maybe a few milliseconds—delay. So the communication isn’t in real time, even though it seems like it is. Our brains subconsciously pick up on the fact that things aren’t quite right. And the fact that things are out of sync and we’re accustomed to them being in sync when it’s face-to-face communication, our brains try to look for ways to overcome that lack of synchrony. After a few calls a day, it starts to become exhausting.
Does this mean, if I'm naturally slow to react even in real life, it'll be exhausting for the interlocutor?

Then when giving answers I'm even less certain. For example I see occasional how-to questions which (IMO) are ridiculously complex in bash, awk, sed, etc. but trivial in python, (<10 lines, no non-standard libraries). On such questions I wait and see if other answers are forthcoming. But if they get no answers, I'm not sure if I should give my 10 lines of python or not.
-
There is an observable widespread tendency to give an awk answer to almost everything, but that should not be inferred as a rule to be followed, and if there's (say) a Python answer that involves less programming then surely that is quite on point as an answer for a readership of users.

This isn’t an accident. OpenOffice’s sidebar code was copied and incorporated into LibreOffice. The Apache OpenOffice project uses the Apache License, while the LibreOffice uses a dual LGPLv3 / MPL license. The practical result is LibreOffice can take OpenOffice’s code and incorporate it into LibreOffice — the licenses are compatible. On the other hand, LibreOffice has some features — like font embedding — that don’t appear in OpenOffice. This is because the two different licenses only allow a one-way transfer of code. LibreOffice can incorporate OpenOffice’s code, but OpenOffice can’t incorporate LibreOffice’s code. This is the result of the different licenses the projects chose.
What part of LGPLv3 / MPL prevents LibreOffice code from being incorporated back into OpenOffice's Apache Licensed code??
