    1. En muchas de las ocasiones los seres humanos estamos sujetos a las actividades que otros hacen para guiarnos o quizá imitar comportamientos. Es por ello que existen una cantidad e prohibiciones de copiado para evitar la repetición de contenidos..

    1. La desinhibición a los actos violentos y su diafanada presencia a lo largo de la historia del ser humano, se han visto incitadas y provocadas durante nuestra época por el sistema social con el cual hemos sido instruidos. Cabe denotar que la autora hace énfasis en la violencia de género, parafraseando conceptualizaciones de la ideología feminista nos explica: la postura social de la masculinidad y la feminidad, sus interrelaciones afectadas por la corrosión del comportamiento sustentándolo con una explicación psicoanalítica y la afectación que las organizaciones y el ser humano efectúan sobre el ser humano.. Al final de texto Rita hace un comunicado dirigido a los hombres, induce la idea de ser participes en la solución del problema social puesto que no somos ajenos a él. De esta forma este texto es dirigido para toda persona que deseé informarse sobre uno de los problemas sociales más importantes de nuestra historia, pues Desde el 2009 las muertes violentas de mujeres —y de hombres— se dispararon de manera significativa; sólo en 2010 y 2011 los homicidios femeninos casi se duplicaron. Esta tendencia sólo se revirtió en 2014 y 2015, en el 2016 y hasta el momento la cifra continúa con alzas. Los registros también evidencian una creciente tendencia de las muertes violentas de mujeres. Aún con el confinamiento estricto que paralizó gran parte de las actividades y la movilidad el total de asesinatos de mujeres creció 0.6% en comparación con el mismo periodo del 2019. Como último quiero remarcar lo que dijo la autora "Los hombres deben entrar en las luchas contra el patriarcado, pero que no deben hacerlo por nosotras y para protegernos del sufrimiento que la violencia de género nos inflige, sino por ellos mismos, para liberarse del mandato de la masculinidad."

    1. Concrete Mixing Plant

      As a company, we are sensitive to using advanced building technologies effectively for all our building and construction projects. As a matter of fact, the most important factor underlying the quality and safety standards that our company has achieved in all its projects so far is that we use building technologies effectively. We always follow technological developments that will help us achieve much better standards in construction applications. For this, we use the most innovative concrete mixing plant technology to realize the concrete applications without exception at the highest quality. We have been working with Elkon for many years to meet this need that has arisen in line with the intensive work of our company. As well as the high-quality standards of the company's concrete mixing plant products, we can ensure a high compatibility in our work with service offerings focused on projects. For this reason, we are working with Elkon firm on the need for a concrete mixing plant for each project that our company will start to realize. In addition to volume capacity options, mixers have a very rich model variety by means of technical functions. In this way, we can supply concrete plants, which are suitable for our needs created by the concrete application capacity in our project, from the company. With its superior technology and high-quality durability, we do not encounter any problems in our applications on concrete, which is the most common thing we use in our project sites. The serious problems that technical problems may cause in terms of construction projects are at everyone's discretion. Our company will continue to work in harmony with the company for all construction and building projects in the future, as it has enabled us to encounter these problems today. We would like to thank them for their quality responses to our requests up to now.

    1. A circular electronics system - one in which resources are not extracted, used and wasted, but re-used in countless ways - creates decent, sustainable jobs and retains more value in the industry.

      This sentence caught my eye because it seems like an obvious solution to reduce the amount of e-waste and materials used to create new products. It is upsetting to see that many people resort to being wasteful and using up the world's resources at such a quick rate before thinking about reusing and remodeling what we have already created.

    1. A Nix expression describes everything that goes into a package build action (a “derivation”)

      Come up with an ultimate definition for what a "derivation" is.

      So round up all the places where it is mentioned across Nix* manuals, and check out these:

      From Nix Pills section 6.1. The derivation function (see annotation):

      A derivation from a Nix language view point is simply a set, with some attributes. Therefore you can pass the derivation around with variables like anything else.

      So there is clearly an ambiguity between what derivations are perceived to be and what is stated in the Eelco Dolstra's PhD thesis. Or maybe I'm having issues with reading comprehension again...

    2. 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 the output attribute in the Nix expression has never been explicitly set, right?

    3. A derivation causes that derivation to be built prior to the present derivation; its default output path is put in the environment variable.

      That is, if an input attribute is a reference to a derivation in the Nix store, then

      1. that derivation is built first (after a binary substitute is not found, I presume), and
      2. the path to the built package (for a better word) is handed to the shell build script.
    4. 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 the derivation primitive is called (explicitly or implicitly, as in mkDerivation) 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 usingmkDerivation`. These are translated into low-level store derivations (implicitly by nix-env and nix-build, or explicitly by nix-instantiate).

    5. The command nix-shell will build the dependencies of the specified derivation, but not the derivation itself. It will then start an interactive shell in which all environment variables defined by the derivation path have been set to their corresponding values, and the script $stdenv/setup has been sourced. This is useful for reproducing the environment of a derivation for development.

      QUESTION: What exactly does nix-shell execute from the Nix expression (i.e., shell.nix, default.nix, etc.)?

      ANSWER: Based on my current understanding, the answer is everything. It calls $stdenv/setup (see annotation below) to set up the most basic environment variables (TODO: expand on this), and "injects" the most common tools (e.g., gcc, sed) into it.

      It also defines the phases (TODO: verify this) and builder functions, such as genericBuilder. For example, the default builder is just two lines:

      source $stdenv/setup

      TODO: pkgs/stdenv/generic/builder.sh is a mystery though.

      QUESTION: Once dropping into nix-shell, how do I know what phases to execute by looking at a default.nix? (E.g., [..]freeswitch/default.nix)

      ANSWER: As far as I can tell, one can override the phases in their Nix build expression (to build the derivation, see at the bottom), but they won't get executed as only the $stdenv/setup (see above) will get sourced, and no builders are called that, in return, invoke the phases (again, see above).

      So if one is using nix-shell

      • to create/hack on a package, the person has to manually invoke the builder or phases (TODO: still fuzzy on this subject)

      • to set up an environment, then one doesn't even have to worry about builders/phases because we just use nix-shell to clear the environment and to inject tools that we need for a given task

      QUESTION: When dropping into nix-shell, is this Nix expression (i.e., freeswitch/default.nix) executed? Or just parts of it?

      ANSWER: As stated above, all of the input Nix expression is evaluated, but no builders and build phases are called; although, nothing prevents one to override the phases, in case they are creating/hacking on a package.


      The command nix-shell will build the dependencies of the specified derivation, but not the derivation itself.

      What is the "derivation" here exactly? I know that it is a build expression, but does that mean the default.nix (or other Nix expression) nix-shell is invoked with?

      <sup>This statement also seems like a contradiction with how `nix-shell` works (i.e., if one issues `nix-shell -p curl`, then `curl` will be available in that sub-shell), but `-p` acts like a shortcut to as if `curl` had been listed in `buildInputs` so this is not the case.</sup>

      ANSWER: I have the feeling my confusion comes from the fact that the term "derivation" is used ambiguously in the manuals, sometimes to mean multiple things (see list below).

      TODO: Substantiate this claim, and make sure that it not coming from my misunderstanding certain topics.

      • Nix build expression (such as default.nix) whose output is going to become the store derivation itself (see last item at the bottom about the Nix manual's glossary definition)

      • store derivation.

      Had multiple cracks at unambiguously define what a derivation is, and here's a list of these:

    6. $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!

    7. The function mkDerivation in the Nixpkgs standard environment is a wrapper around derivation that adds a default value for system and always uses Bash as the builder, to which the supplied builder is passed as a command-line argument. See the Nixpkgs manual for details.

      "Documented" in the Nixpkgs manual under 6.1 Using stdenv.

      Used the double-quotes above because I don't consider it well documted. Will give it a try too; worst case scenario is that I'll fail as well.

    8. C.12. Release 1.6 (2013-09-10)In addition to the usual bug fixes, this release has several new features:The command nix-build --run-env has been renamed to nix-shell.
    9. See annotations with the build-phases tag.

      Why are the build phases not enumerated in the Nix manual? If the instructions on how to create a derivation (and thus, a package) then why not go all in instead of spreading out information in different manuals, making the subject harder to grasp?...

      (By the way, it is documented in the Nixpkgs manual under 6.5 Phases; not sure why it is not called build phases when every page refers to them like that.)

    10. Chapter 14. A Simple Nix Expression

      This such a stupid move to go through a derivation example before introducing the language.

    11. Add the package to the file pkgs/top-level/all-packages.nix. The Nix expression written in the first step is a function; it requires other packages in order to build it. In this step you put it all together, i.e., you call the function with the right arguments to build the actual package.

      In addition to this rant, step 3. should be more generic, instead of tying it to Nixpkgs; at least, either show how to build your own Nix expression repo, or don't add this step, but it is not at all necessary to write a derivation. There is a Nixpkgs manual for a reason.

    12. $ nix-env -i firefox --substituters ssh://alice@avalon This works similar to the binary cache substituter that Nix usually uses, only using SSH instead of HTTP

      So a substitute is a built binary for a given derivation, and a substituter is a server (or binary cache) that serves pre-built binaries, right?

      Update: in the next line it says that "it will fall back to using the binary cache substituter", so I guess that answers it.

    13. substitute

      this is another key topic. Also:

      • substitute vs. substituter => this (I think)

      See annotations with the substitute tag

    14. 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?

    15. closure

      Another gem: who knows what a "closure" is.

      [This highlight] (a couple lines below) implicitly explains it though:

      The command nix-copy-closure copies a Nix store path along with all its dependencies to or from another machine via the SSH protocol. It doesn’t copy store paths that are already present on the target machine.

      or this, also just a couple lines below:

      the closure of a store path (that is, the path and all its dependencies)

    16. the closure of a store path (that is, the path and all its dependencies)
    17. The command nix-copy-closure copies a Nix store path along with all its dependencies to or from another machine via the SSH protocol. It doesn’t copy store paths that are already present on the target machine. For example, the following command copies Firefox with all its dependencies:
    18. subscribes you to a channel that always contains that latest version of the Nix Packages collection.

      That is a misleading statement. The latest version is where the master branch points, isn't it?

      So a channel points to a Nixpkgs commit (on a branch named after the channel) where all packages inside are deemed stable, and all packages are built to have available binary substitutes by a (hydra) build farm.

    19. A Nix channel is just a URL that points to a place that contains a set of Nix expressions and a manifest.
    20. garbage collector roots

      Definitely avoid this, when a term is used but only introduced formally way later. (There is also a reference to "garbage collector roots" almost at the beginning as well.)

    21. $ nix-env --switch-profile /nix/var/nix/profiles/my-profile $ nix-env --switch-profile /nix/var/nix/profiles/default These commands switch to the my-profile and default profile, respectively. If the profile doesn’t exist, it will be created automatically.

      learn more about profiles; creating new profiles was new info

    22. Chapter 10. ProfilesProfiles and user environments are Nix’s mechanism for implementing the ability to allow different users to have different configurations, and to do atomic upgrades and rollbacks.
    23. user environment
    24. In Nix, different users can have different “views” on the set of installed applications. That is, there might be lots of applications present on the system (possibly in many different versions), but users can have a specific selection of those active — where “active” just means that it appears in a directory in the user’s PATH. Such a view on the set of installed applications is called a user environment, which is just a directory tree consisting of symlinks to the files of the active applications.
    25. nix-env -qas

      ... and it takes AGES to complete

    26. 4.3.1. Change the Nix store path prefix

      There is a lot of place in this manual (and probably in the others as well) where the prefix is referred to (usually with italics, such as "prefix/store"), so in the book

      • this should be linked to this section (or the one in the book), and

      • establish a clear and well-communicated notation to convey this

    27. 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.
    28. 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.

    29. reentrancy
    30. You can uninstall Nix simply by running: $ rm -rf /nix
    31. $ mkdir /nix $ chown alice /nix

      Traditionally, when a command should be invoked with sudo, it is either included in the example, or the shell indicator is # instead of $.

    32. To explicitly select a single-user installation on your system:

      It should be noted in this section also that since nix 2.1.0, single user install is the default.

    33. nix-shell '<nixpkgs>' -A pan

      What is happening here exactly?

      nix-shell's syntax synopsis always bugged because it looks like this

      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 that path 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 the NIX_PATH environment variable, and -A pan looks up the pan attribute in pkgs/top-level/all-packages.nix in the Nixpkgs repo.

    34. since packages aren’t overwritten, the old versions are still there after an upgrade. This means that you can roll back to the old version:

      Wouldn't hurt to tell folks that this is a convenience layer, and one could also just use the old package from the /nix/store, even though that path would be long and obscure; one could use symlinks of course.

      Or, onc could just use nix-shell -p that specifies a specific version (that's already in the store), but, of course, it's not that simple...


    1. A derivation from a Nix language view point is simply a set, with some attributes. Therefore you can pass the derivation around with variables like anything else.
    2. the single repository technique. The natural implementation in Nix is to create a top-level Nix expression, and one expression for each package. The top-level expression imports and combines all expressions in a giant attribute set with name -> package pairs. But isn't that heavy? It isn't, because Nix is a lazy language, it evaluates only what's needed! And that's why nixpkgs is able to maintain such a big software repository in a giant attribute set.

      This is the gist of how Nixpkgs works (and how it is organized).

    3. 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 if f(c) = c. This means

      f(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 of f, because f(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


      Other resources in no particular order:

      QUESTION: How the hell did they come up with the idea of using this with Nix and package management? (..and who? I remember a video saved somewhere, but maybe that was about overlays)

      QUESTION: ... and how does it work in this context?

      ANSWER: Well, not an answer yet, but this may be something in the right direction:


    4. there's no ldconfig cache either. So where does bash find libc?

      QUESTION: What is ldconfig cache?

      QUESTION: What is libc and why does Bash need it?

    5. 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?

    6. In Nix there is the notion of a derivation rather than a package. The difference can be subtle at the beginning, so I will often use the words interchangeably.

      Doesn't really say anything but thought it important to highlight this first mention of derivations in the Nix Pills.

    7. From an administrator's point of view: you can use containers. The typical solution nowadays is to create a container per service, especially when different versions are needed. That somewhat solves the problem, but at a different level and with other drawbacks. For example, needing orchestration tools, setting up a shared cache of packages, and new machines to monitor rather than simple services.

      This is a very good pointer; I guess it refers to systemd services when it mentions "simple services".

    1. Specifying a name and a src is the absolute minimum Nix requires.

      Didn't they mean what mkDerivation requires?

      I have been jumping around in this manual, so not sure about what arguments does derivation require.

    2. For convenience, you can also use pname and version attributes and mkDerivation will automatically set name to "${pname}-${version}" by default.

      The error messages are not helpful when one messes up the input attribute set ofmkDerivation (i.e., either name, or pname and version attributes have to be present); see Nixpkgs issue #113520.

    3. 6.1. Using stdenv
    4. fetchpatch works very similarly to fetchurl with the same arguments expected. It expects patch files as a source and and performs normalization on them before computing the checksum. For example it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
    5. 19.3. Submitting security fixes Security fixes are submitted in the same way as other changes and thus the same guidelines apply. If the security fix comes in the form of a patch and a CVE is available, then the name of the patch should be the CVE identifier, so e.g. CVE-2019-13636.patch in the case of a patch that is included in the Nixpkgs tree. If a patch is fetched the name needs to be set as well, e.g.: (fetchpatch { name = "CVE-2019-11068.patch"; url = "https://gitlab.gnome.org/GNOME/libxslt/commit/e03553605b45c88f0b4b2980adfbbb8f6fca2fd6.patch"; sha256 = "0pkpb4837km15zgg6h57bncp66d5lwrlvkr73h0lanywq7zrwhj8"; }) If a security fix applies to both master and a stable release then, similar to regular changes, they are preferably delivered via master first and cherry-picked to the release branch. Critical security fixes may by-pass the staging branches and be delivered directly to release branches such as master and release-*.
    6. 18.6. Patches Patches available online should be retrieved using fetchpatch. patches = [ (fetchpatch { name = "fix-check-for-using-shared-freetype-lib.patch"; url = "http://git.ghostscript.com/?p=ghostpdl.git;a=patch;h=8f5d285"; sha256 = "1f0k043rng7f0rfl9hhb89qzvvksqmkrikmm38p61yfx51l325xr"; }) ];

      ... and from Chapter 11:

      fetchpatch works very similarly to fetchurl with the same arguments expected. It expects patch files as a source and and performs normalization on them before computing the checksum. For example it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.

      ... and also adding highlight of 19.3. Submitting security fixes

      because these are the only places I've seen fetchpatch mentioned.

      From the wild in freeswitch/default.nix in Nixpkgs:

    7. 6.5. Phases

      Entre 2008 y 2013, en el terreno llamado Arroyo El Navajo, ubicado a 94 kilómetros de la frontera con Estados Unidos, se encontraron los fragmentos de huesos de al menos 24 mujeres que fueron secuestradas en Ciudad Juárez durante el periodo en el que la zona estuvo militarizada por el despliegue de agentes federales y soldados, como parte del “Operativo Conjunto Chihuahua

    1. nix-channel --list #<output> nixpkgs https://nixos.org/channels/nixpkgs-unstable The command returns a name for each channel (e.g., nixpkgs) and an URL. Note When running nix-env with the parameter -A, one can select the channel to get the package from. Such a command looks like nix-env -iA channelname.packagename.

      Instead of #<output> it should have said channel-name instead at the top nix-channel example to keep it consistent.

    2. 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.

    3. However, it makes the “Making the package available to the user” more complex. Nix heavily relies on environment variables to make this possible

      And symlinks

    1. example: get an environment which is used to build irssi (also see nix-shell) $ nix-build $NIXPKGS --run-env -A irssi example: get a persistent environment which is used to build irssi $ nix-build $NIXPKGS --run-env -A irssi --add-root

      nix-build <path> --run-env has been superseded by nix-shell. From Nix manual section C.12. Release 1.6 (2013-09-10):

      The command nix-build --run-env has been renamed to nix-shell.

    2. git clone --depth=1 https://github.com/nixos/nixpkgs

      i should remember this to only get last commit, which basically means to only care about the data, and discard commit history.

    1. No obstante, aunque desconocemos qué partícula constituye la materia oscura, ésto no significa que no entendamos cómo se comporta.

      El comprender el comportamiento de la materia oscura es un gran aporte a la ciencia

    2. A finales de la década de los 70 y comienzos de la década de los 80 del siglo XX, la necesidad de materia oscura no bariónica para explicar la formación de estructuras cosmológicas, junto con una muestra cada vez mayor de curvas de rotación de galaxias que mostraban un comportamiento plano, consolidaban la hipótesis de la existencia de materia oscura en el Universo.

    3. Casi 100 años después de que se empezara a hablar de materia oscura, la realidad es que no sabemos lo que es, pero afortunadamente sabemos qué no es.

      A pesar de todas las investigaciones, nos falta mucho por aprender y descubrir.

    1. EBF was much more potent than Pax5 in inducing B celldevelopment, as its expression in MPPs yielded at least 100-foldmore B lineage progeny than did expression of Pax5 (Fig. 3band data not shown). These data suggest that promotion of B cellgeneration from MPPs by EBF is not mediated solely throughactivation of Pax5 expression.

      EBF expression represses and restricts alternative lineage genes, also help promote B cell independently of Pax 5.

    1. However, I do feel that the way that he speaks is particu-larly African American. Th is refers more to his rhetoric, intona-tion, and style. However, his speech or the extent to which he plays up his Black manner of speaking varies depending on his setting.

      what is a "black manner" of speaking? is the same as the statement above it that he speaks African American? does this imply the language or just a form of speaking like he can communicate and he knows what African Americans want?

      The website below explains that speaking African American is a unique vocabulary with different accents and grammar

    1. “You are free to eat from any tree in the garden;(W) 17 but you must not eat from the tree of the knowledge of good and evil,(X) for when you eat from it you will certainly die.”

      God instructed Adam and Eve to eat whatever they desired, though prohibited them to eat from the tree of the knowledge of good and evil. In Robin Wall Kimmerer's "Skywoman Falling", she explained how in Indigenous culture, they follow Original Instructions. These "instructions" are not rules but rather guidelines for each person. Kimmerer explains how during Skywoman's time, the first people's understanding of the Original Instructions were to care for the and have respect for hunted animals, value family, and hold respectful ceremonies for their beliefs.

    2. 19 Now the Lord God had formed out of the ground all the wild animals(AA) and all the birds in the sky.(AB) He brought them to the man to see what he would name them; and whatever the man called(AC) each living creature,(AD) that was its name. 20 So the man gave names to all the livestock, the birds in the sky and all the wild animals.

      God had given Adam the responsibility to name all living creatures on Earth after the first days of creation. In Ursula K. Le Guin’s “She Unnames Them”, the idea of how labels or given names could take away from “personal choice” and “freedom” was explored throughout the text. Instead of believing that humans are above animals and living creatures, Buddhists view animals as very sacred beings and are to be shown with respect and to never be harmed. They also believe that humans can be reborn as animals, all interconnected within one another, supporting their beliefs of showing extreme care towards animals and allowing them to live freely.

    3. 4 “You will not certainly die,” the serpent said to the woman.(AR) 5 “For God knows that when you eat from it your eyes will be opened, and you will be like God,(AS) knowing good and evil.”

      This verse is referenced heavily throughout contemporary literature. The idea of being tricked or pressured into something you are told is wrong.

      the intertextual connection is to the classic tale of, "Little Red Riding Hood." The girl is strictly instructed by her Grandmother to stay on the path to her house. Instead, naive Little Red is tricked by the Wolf to telling her where she is going. The Wolf goes to the Grandmother's house and eats her.

    4. When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable(AT) for gaining wisdom, she took some and ate it.

      Despite being told by God that she and her husband were not allowed to eat the fruit from the tree of the knowledge of good and evil, Eve gave into her temptations. The idea of the "forbidden fruit" has been carried into other pieces of literature, using an apple to symbolize a character's temptation leading to downfall.

      For example, in the fairy tale, Snow White and the Seven Dwarfs, when Snow White eats the poisoned apple, offered by the evil witch, who parallels the serpent, she falls into a death-like sleep.

    5. he will crush[j] your head,(BL)    and you will strike his heel.”

      God curses the serpent after deceiving Eve in the garden, and creates "enmity between [the serpent] and the woman." In the "Harry Potter" series by JK Rowling, the serpent is a symbol of evil, and near the end of the books, is the only piece of evil left to destroy before good can truly be restored.

    1. Gary Nabhan has written, we can’t meaningfully proceed with healing, with restoration, without “re-story-ation.”

      This is an example of allusion- Robin Kimmerer is referencing Gary Nabhan's literature known as "Food from the Radical Center" without directly naming the text. This book relates how we eat with stories of collaboration, calling on each of us to restore the nation's capacity to feed and nourish. This is a connection to the message behind "Skywoman Falling."

    2. Tree of Life

      The 'Tree of Life' has been present throughout many cultures and religions across history. It has been known by many different names but the meaning is always a source of life or a creator. The ancient Egyptians, Christians, Myahs, and Assyrians all believed in this 'Tree of Life.'

    3. Original Instructions.

      These instructions are about creating peace with ourselves, others, and the land. The idea of pacifism and hospitality were encouraged. These are teachings that are passed down generation to generation among many Indigenous groups.

    4. Turtle Island

      Turtle Island is based on the belief that the land was created on the shell of a turtle. Hinduism also has the similar belief that the world is built on a turtle

    1. El matrimonio igualitario Argentina, Uruguay, México, Brasil y Colombia son los únicos países de América Latina que han legalizado el matrimonio de parejas homosexuales, con todas las condiciones legales que tienen los matrimonios convencionales. De igual manera, Holanda, Bélgica, Suecia, Alemania, Sudáfrica, España, Inglaterra, Portugal y otras 12 naciones más han hecho lo propio.   Entretanto, sólo 11 países permiten la unión civil entre parejas del mismo sexo (no incluye todos los derechos legítimos maritales) entre estos Ecuador, Chile, Austria, Italia y Grecia. Cambio de identidad El proceso de cambio de género o sexo es un proceso quirúrgico y psicológico que contempla el cambio físico. En la actualidad, naciones como Venezuela, Colombia, Uruguay, Bolivia y Perú permiten que la transformación también sea legal, con el cambio del nombre y género en los documentos de identidad de las personas LGBTI. Sin embargo, en Brasil y Argentina, este tipo de decretos han sido desaprobados o son procesos difíciles por lo riguroso de los exámenes y requisitos que truncan el derecho al trámite. Igualdad en derechos patrimoniales Las garantías, protecciones legales en los matrimonios tras el fallecimiento y divorcio también son logros alcanzados en menos de 20 años por la comunidad LGBTI. Pero estos aún están condicionados dependiendo del país, por la diferencia entre permitir la unión civil (algunos derechos de cónyuges) o el matrimonio igualitario (derechos legítimos).   Adopción homoparental Uruguay, México, Canadá (el primer país en permitirlo en 1999) y algunos estados de EE.UU. han legalizado la adopción para personas unidas del mismo sexo. Asimismo, España, Holanda, Francia y otros permiten que las parejas no heterosexuales puedan tener hijos por medio de la adopción legal. Protección a víctimas de discriminación Hasta 1948 la homosexualidad era considerada una enfermedad mental, pero esto cambió lo que permitió la apertura de sistemas de protección a víctimas de discriminación y agresión. En la actualidad, existen programas de atención social y judicial para el seguimiento de los casos de hostigamiento y asesinatos contra los homosexuales. Además hay coberturas de salud gratuitas para tratar enfermedades como el sida y la programas de integración laboral en distintas áreas.

    1. It will find there is "very little evidence that the virus is transmitted in schools",

      The reporter interviewed Professor Russel Viner, president of Royal College of Pediatrics and Child Health. Apparently, a study was conducted through April to June which collected information of 20,000 students and 100 teachers yet there is no link to this study, did not get peer reviewed or published. It is all just claims at this point. We have no knowledge if these are private schools or public, if there were any safety measures in place, if this included online classes vs in class.

      However, according to CDC and the respected studies it cited, there seems to be lower transmission rates among children and transmission from child to family, but this remains inconclusive. There still needs to be more evidence to be gathered.

    1. If your hosting provider does not support HTTPS, the following options are available: You can contact your web hosting provider: tell them you want a free HTTPS certificate through Let’s Encrypt. You’re probably not the only one using your web hosting provider service who wants HTTPS. You can request that your web hosting provider offer Let’s Encrypt HTTPS certificates as a free part of their hosting package. An effective way to make this ask is through email, their help desk system, or by contacting the web hosting provider through social media. You can switch to a different web hosting provider. Find a web hosting provider who offers full HTTPS support as part of their web hosting package by checking our list. You might be able to use Certbot. If you have SSH access to the server your website is hosted on, you might be able to use Certbot. You will need to know the software and system your server is running on. After you confirm the software and system information, you can use the dropdown menus above to generate specific instructions for running Certbot on your server through the command line.
    1. ABSTRACTLet’s Encrypt is a free, open, and automated HTTPS certificate au-thority (CA) created to advance HTTPS adoption to the entire Web.Since its launch in late 2015, Let’s Encrypt has grown to become theworld’s largest HTTPS CA, accounting for more currently valid cer-tificates than all other browser-trusted CAs combined. By January2019, it had issued over 538 million certificates for 223 million do-main names. We describe how we built Let’s Encrypt, including thearchitecture of the CA software system (Boulder) and the structureof the organization that operates it (ISRG), and we discuss lessonslearned from the experience. We also describe the design of ACME,the IETF-standard protocol we created to automate CA–server inter-actions and certificate issuance, and survey the diverse ecosystemof ACME clients, including Certbot, a software agent we created toautomate HTTPS deployment. Finally, we measure Let’s Encrypt’simpact on the Web and the CA ecosystem. We hope that the successof Let’s Encrypt can provide a model for further enhancements tothe Web PKI and for future Internet security infrastructure.

    1. d the mother often says “Don’t be like niggers” when the children are bad. A frequent phrase from the father is, “Look how well a white man does things.”

      They are taught that the n-word is shameful and bad while acting white is somewhat a higher class that they should be aiming for. This passage reminds me of a poem that I read in the past named Incident by Countee Cullen. In it is the incidents of the narrators encounters with racism and how it affected them even by an older age. This passage is similar as in the mother telling her children how to act in a certain way according to a certain ethnicity is impactful in a negative way.

    1. 7-Eleven moves to support animal welfare By Nick Hall | 17 Feb 2019 View comments Global convenience chain, 7-Eleven has made major changes to its supplier sourcing agreement, eliminating caged eggs for the first time. The move follows ongoing criticism of the Australian cage egg farming industry, with several brands and chains making the early decision to move to wholly sustainable sourcing in-line with welfare standards. Working closely with suppliers across all states, 7-Eleven has now ensured that only free range eggs would be available for order by all stores. Clayton Ford, General Manager Corporate Affairs, 7-Eleven said the decision to phase out cage eggs was developed in accordance with franchisee wishes, with the convenience giant announcing it will increase support to assist in the transition. “Whilst our franchisees are free to engage with alternative suppliers due to our franchise agreement, we will continue to work alongside them to encourage their involvement in this initiative by sourcing free range eggs via our centralised supply chain,” Ford said. “We recognise that this is just one step, and we will continue to review animal welfare commitments in our supply chain and 7-Eleven branded products as opportunities arise.” Want to launch a convenience store of your own?

    1. WHEN it comes to the state of the environment, it’s easy to get swept up in the doom and gloom of it all. Global warming, high pollution levels, climate change and waste disposal all dominate the headlines, painting a bleak picture of what’s to come. But just because it seems hopeless doesn’t mean it is.T roubled times call for ingenious solutions, and Australia is home to some of the brightest ecovators in the world, like Robert Pascoe, Managing Director of environmental solutions company Closed Loop.Through its Simply Cups initiative, Closed Loop is tackling Australia’s overwhelming waste problem by teaming up with 7-Eleven to save 70 million coffee cups from landfill this year — equivalent to the number they sell each year. While the most sustainable option is forgoing a disposable cup for a reusable one, some circumstances are beyond your control. Like your inability to remember anything before you’ve had your morning coffee. Which is a bit of a catch 22, isn’t it? That’s why 7-Eleven are installing dedicated coffee cup recycling bins in over 200 of their stores nationally, as well as funding 50 other large-scale locations including offices, universities and construction sites as part of the initiative. Coffee cups are one of the largest contributors to litter waste in Australia, with an estimated one billion ending up in landfill each year because they are not recycled.Yep, unfortunately you read that right: one billion cups.Coffee cups are one of the largest contributors to litter waste in Australia, with an estimated one billion ending up in landfill each year because they are not recycled.“T here’s a lot of misinformation out there,” Mr Pascoe said. “The consumers aren’t at fault because ultimately they don’t know what can be recycled and what can’t. I think if we can get that information out there, then people will demand products that are made from recycled materials.”For the majority of us, learning that our disposable coffee cups fall into the category of what can’t be recycled is both confusing and devastating. But, as Mr Pascoe says: “You can’t unknow something once you know it.”“Part of the problem is they didn’t know they weren’t being recycled. A lot of people said, ‘oh no, I put my coffee cup into the recycling to be recycled’, but of course, they’re not,” he continued.A nd why is that, exactly? It’s because most paper coffee cups are lined with a waterproof plastic that makes them hard to recycle — but not impossible. And that’s where Simply Cups comes in. “We’ve come up with a system that can actually recycle these cups if we keep them separate. We’ve got technology available now to do it, but we have to have coffee cups kept as a separate stream. Or anything that has the plastic lining of milk cartons or juice boxes,” Mr Pascoe said. The technology he’s referring to is “kind of like an organic solvent” that works to separate compound materials. Invented by Dennis Collins in Ballarat, the technology was initially designed to separate the PVC material from the hessian used in truck liners and advertising banners.“Dennis called us and said, ‘I’ve got a solution for your coffee cups’,” Mr Pascoe said. “So now we’re building a plant that can process around 150 million coffee cups per year, which is about 1.5 thousand tonnes. That will only be about 10 per cent of disposable coffee cups alone, so we’re going to need quite a few of these plants eventually. We have the solution, but we really need the coffee cups. “That’s why we started the Simply Cups program.”And that’s where coffee addicts come in. Once they drop their coffee cups into a designated recycling bin, they will then be taken to a processing plant using this new technology. The inner plastic lining of the cups will be removed and then recycled into things like plastic outdoor furniture, safety equipment and food trays.A nother eco-minded initiative helping solve Australia’s waste problem is the anti food-waste website, Yume. The website fights food waste — which is a huge problem in Australia — by allowing consumers to buy surplus and unsold food from restaurants and cafes at half the price. The ‘wholesale marketplace for surplus food that saves you money while saving the planet’ shares the same idea as ‘YWaste’, an app allowing retailers to sell food that would otherwise be thrown away.Over its 40-year history, Patagonia has donated about $114 million to grassroots environmental organisations. Over its 40-year history, Patagonia has donated about $114 million to grassroots environmental organisations. Their advertising has begged consumers not to buy things they don’t need (even their own products) and they’ve implemented a program that repairs their products for free rather than replace them. Their commitment to the environment is reflected in the materials of their products too; wetsuits are made of natural rubber and raincoats are made from recycled plastic bottles. This year, the company launched Patagonia Action Works, a digital platform that aims that aims to connect people with environmental nonprofits, helping them get involved through events, petitions, and volunteering.H &M, too, are doing their bit to close the loop on fashion waste with their global campaign encouraging customers to recycle their clothes. They launched their garment collecting initiative in 2013, asking customers to drop off any unwanted items from their closets. Depending on the condition of the clothing, the items are either distributed to second-hand stores for resale, or recycled into other items like yarn, rags, and insulation materials.And just look at Elon Musk. He’s raking in bajillions of dollars every minute almost exclusively thanks to Tesla and SolarCity, which have disrupted an entire industry. While some snigger at his grand ideas — let’s colonise Mars! — the accomplishments of how he has changed the way we shop for cars are hard to deny.A fter a complicated relationship with French beauty giant L’Oreal, The Body Shop is now in the hands of ethical Brazilian beauty brand Natura, promising to return to its pioneering ethical business.“All of us share the aim of doing business as a transformational force for good and a force for change for society and for the environment. We couldn’t think of a better union to nurture our brand’s commitment to naturality and sustainability,” said the Body Shop’s Communications Manager, Jessica Styles. “In 2016, The Body Shop launched its new sustainability plan, Enrich Not Exploit, supporting the brand’s vision to be the most ethical and sustainable global business in the world.”“All of us share the aim of doing business as a transformational force for good and a force for change for society and for the environment. We couldn’t think of a better union to nurture our brand’s commitment to naturality and sustainability,”Jessica Styles, Body Shop’s Communications Manager The plan set fourteen targets to help The Body Shop become a "truly sustainable business", including powering all its stores with 100 per cent renewable energy, overhauling product packaging by slashing the use of fossil fuel-based wrapping and designing new sustainable innovations. This year there’s a special focus on protecting Red Pandas in Nepal, a species currently on the endangered list.“Now more than ever, companies have the platforms and frameworks to not only voice doing good for the planet and people but to also act on it. The more we see big brands doing their bit, the more it becomes entrenched as something that not only employees but customers should be thinking about,” Styles said. “It’s the big corporations of the world that can help foster and influence this through their own businesses.” Skin care brand Youth to The People has made a conscience decision to use 100 per cent recyclable packaging. Co-founder Joe Cloyes says the decision reflects the brand’s philosophies.“We believe in creating as little waste as possible, we believe in cruelty-free products, and we believe in sourcing the best ingredients for your health and your skin. It's just that simple,” he said. “Modern consumers care about their environment just as much as they care about their healthy skin, and they're very much connected. We have found it's very important to people.”FIND OUT how many cups of coffee you could be recycling EVEry yearHow many cups of coffee do you drink every day?How many days per week do you drink coffee?How many weeks per year do you drink coffee?Calculatecups of coffeecould be recycled These are but a few eco-minded initiatives that offer Australians the chance to do their part in securing a cleaner future for generations to come. For every company that spills millions of gallons of oil into our oceans, there are plenty more companies operating under a socially responsible ethos. They recognise enterprise and environmental responsibility can in fact go hand-in-hand.“I think every organisation should have a sustainability policy,” Mr Pascoe said. “There are plenty of organisations around that can have a positive impact on the environment. We’re talking about the effect they have on the environment, the way they consume energy, and the way they manage their waste. In my world, there’s no such thing as waste.” Over one billion cups end up in landfill each year because they are not recycled. That’s why 7-Eleven has joined forces with Simply Cups to establish cup recycling in Australia. Save your cups by placing them in a Simply Cups bin at any participating 7-Eleven #cuprescue.

This isolation can be avoided if you have some to care you. No women in the could be independent but they can live independently only a certain period after they miss something in their life. Everyone will leave you but the one who love you will stick with your downs and ups. Your parents will pass you but your husband be with you until something has happen.

    1. The Hispanic ChallengeThe persistent inflow of Hispanic immigrants threatens to divide the United States into two peoples, two cultures, and two languages. Unlike past immigrant groups, Mexicans and other Latinos have not assimilated into mainstream U.S. culture, forming instead their own political and linguistic enclaves --from Los Angeles to Miami --and rejecting the Anglo-Protestant values that built the American dream.

Thus, even though these numbers turned out to be exaggerated, the authority of their source—the INS—meant that they entered public discourse as a symbol of alarm.29For example, the December 1974 cover of the American Legion Magazinedepicted the United States being overrun by “illegal aliens” (Figure 1.1). Most of the cartoon people in the image are Mexicans storming, en masse, across the U.S.-Mexico border, breaking down a sign that reads “usa border” and another one reading “keep out.” Other immigrants are landing by boats along theEast Coast, flying in and swimming from the Caribbean, parachuting acrossthe Canadian border, and all of them are converging upon, and inundat-ing, the nation’s institutions, most notably welfare, education, housing, jobs, and medical care. Such images were to become more frequent in the nation’s magazines over the next three decades, contributing to an increasingly alarmist d

      I feel that cartoons (in magazines/newspapers/etc) always tend to implicate some type of "joke" because it is illustraited in a way that should just be a slap in the writst just because it is a drawing and it is "funny"because it is a cartoon. But there has been a a lot of cartoons HYSTORICALLY publicly published that no doubt has racism stamped all over it. No difference with this cartoon there is stereotypes of Mexicans with sombreros and almost racing to these facilities. I also think of the illustraitor and what type of person is he and what his/her intensions were to be using effort and tallent on something so RACIST.

    1. Paduans

      Paduans is a Venetian Italian city that was founded by the Trojan price Antenor in 1185 B.C after the destruction of Troy. Antenor who was the founder of the city was said to be a tradior of the Trojans and he delivered Palladio who was the tailsmans of troy to Odysseus and Diomedes and in exchange he recieved salvation for himself and his family. Today Paduans in known to be one of the most beautiful cities in Veneto.

    2. Florentine

      Florentine represents the political scene of Italy at the time and the physiology that ended up getting Dante exiled. Dante considered the Florentine politics to be mischievous, which is why he put a character that represented this in The Inferno. After being exiled, along with many others, Dante considered the results of the politics to be a sin.

      Filippo is based on a Black Guelph, Charles of Valoi, Dante’s political enemy. Charles of Valoi entered Florence with the other Black Guelphs and destroyed much of the city within a few days. The harsh treatment that Filippo sufferers in The Inferno is payback for an earlier offense that the real life Charles of Valoi had done. In The Inferno Filippo’s violent temper is highlighted in the story as a man who had crossed Dante.

    1. Text-Based SourcesSummary of the Final Report of QTD Working Group II.1Nikhar Gaikwad, Veronica Herreraand Robert Mickey*

      ShareKnowledge #QualitativeUAEM

      Al analizar el contenido del texto "Text-Based Sources" (American Political Science Association Organized Section for Qualitative and Multi-Method Research, Qualitative Transparency Deliberations, Working Group Final Reports, Report II.1); hemos determinado algunas reflexiones que deseamos compartir.

    2. The report describes several types of transparency-enhancing practices relevant to text-based sources. Some of these practices improve transparency regarding the process of generating evidence.Clearly identifying asource's locationhelps other researcherslocate and evaluate evidence, expanding the scope and reach of one's research

      Cabe destacar que las recientes discusiones que han surgido sobre la transparencia de la investigación cualitativa en la Ciencia Política han sido un tema de debate serio, de tal manera que ha sido necesario implementar un código de ética con el objetivo de aumentar y reforzar la transparencia en las fuentes basas en texto.

    3. rk.Drawing on QTD deliberations, existing scholarly work, and our own reflections, we discuss a range of transparency-enhancing practices and technologies, the costs and risks attendant with each, and their potential benefit

      Sabemos que gran parte de la investigación considerada "cualitativa" se basa, en el análisis de documentos (fuentes basadas en texto) y que todo este proceso implica un costo, pero es necesario y garantiza una mejor calidad de la información.

      Por esta razón, sostenemos que la transparencia en la información que empleamos de las fuentes basadas en texto ayuda a otorgar mayor claridad en el proceso de investigación y permite adquirir nuevos conocimientos.

    4. Recent discussions about transparency in political science have become fraught with concernsover replicability or even scholarly misconduct. The report of the QTD Working Group on Text-Based Sources emphasizesinstead that the ultimate goal of augmenting transparency is to increase our ability to evaluate evidentiary claims, build on prior research, and produce better knowledge.

      Consideramos que de suma importancia implementar la transparencia en la metodología de selección de las fuentes basadas en texto que utilizamos para compartir información pública.

      Para ello, es necesario hacer un proceso analítico de deliberación de las fuentes basadas en texto; esto consiste en evaluar si los datos que se compartirán abiertamente son "verídicos".

    1. In this way, anthropologists often attemptto understand and appreciate culture from the point of view of the people within it.

      This statement reminds me of when I took an anthropology class here at Lander and our professor showed us a documentary about Julia Roberts living with a Mongolian nomad family for days to learn about and live their culture. The link I have attached is just one part of the documentary. Here she is learning about the Mongolian's relationship with wild horses.

    1. This modulefocuses on biases against social groups,which social psychologists sort intoemotional prejudices, mental stereotypes,and behavioral discrimination. Thesethree aspects of bias are related, but theyeach can occur separately from the others(Dovidio & Gaertner, 2010; Fiske, 1998). Forexample, sometimes people have anegative, emotional reaction to a socialgroup (prejudice) without knowing even themost superficial reasons to dislike them(stereotypes).

      The article talks about how prejudice, stereotypes, and discrimination has a correlation, but can happen separately. I do believe that this is true. You can be prejudice, stereotypical and discriminate towards others and not be aware. You see this happen a lot in this society. This are the people that see no wrong in there behavior and thinks society is suppose to keep accepting there behavior. Times have change from the 70's to now.
