    1. From the Introduction to Ed25519, there are some speed benefits, and some security benefits. One of the more interesting security benefits is that it is immune to several side channel attacks: No secret array indices. The software never reads or writes data from secret addresses in RAM; the pattern of addresses is completely predictable. The software is therefore immune to cache-timing attacks, hyperthreading attacks, and other side-channel attacks that rely on leakage of addresses through the CPU cache. No secret branch conditions. The software never performs conditional branches based on secret data; the pattern of jumps is completely predictable. The software is therefore immune to side-channel attacks that rely on leakage of information through the branch-prediction unit. For comparison, there have been several real-world cache-timing attacks demonstrated on various algorithms. http://en.wikipedia.org/wiki/Timing_attack

      Further arguments that Ed25519 is less vulnerable to - cache-timing attacks - hyperthreading attacks - other side-channel attacks that rely on leakage of addresses through CPU cache Also boasts - no secret branch conditions (no conditional branches based on secret data since pattern of jumps is predictable)

      Predicable because underlying process that generated it isn't a black box?

      Could ML (esp. NN, and CNN) be a parallel? Powerful in applications but huge risk given uncertainty of underlying mechanism?

      Need to read papers on this

    2. More "sales pitch" comes from this IETF draft: While the NIST curves are advertised as being chosen verifiably at random, there is no explanation for the seeds used to generate them. In contrast, the process used to pick these curves is fully documented and rigid enough so that independent verification has been done. This is widely seen as a security advantage, since it prevents the generating party from maliciously manipulating the parameters. – ATo Aug 21, 2016 at 7:25

      An argument why Ed25519 signature alg & Curve 25519 key exchange alg is more secure; less vulnerable to side attacks since the process that generates is have been purportedly verified and extensively documented.

    1. Kernel is already defined by Ruby so the module cannot be autoloaded. Also, that file does not define a constant path after the path name. Therefore, Zeitwerk should not process it at all.
    1. The Hori key enters a Hori lock in such a way as to affirm your suspicion that every key you’ve ever inserted into every lock throughout your entire life was a sham. A false combination — jittery, sticky, imprecise. You realize how badly cut, forged by shoddy means, all the keys you own currently are. Using this Hori key and lock combination is similar to how you might have felt the first time you ever touched a masterfully finished piece of wood — shock at that glassy smoothness you didn’t think could be brought out from the material. The key enters. Within perfectly milled chambers, the driver pins — attenuated by precisely tensioned springs — push against the key pins as the key slides forward in the keyway. The driver pins align to a dead-straight shear line and you feel the key settle with a satisfaction of a meticulously-measured thing spooning its Platonic opposite. Then you twist. The movement of the bolt away from the frame is so smooth — the door having been hung by some god of carpentry with the accuracy of a proton collision path — that you gasp, actually gasp, at the mechanism.

      I love the visceral way Craig Mod describes these Hori key/lock mechanisms. Makes me want to go out and buy one.

    1. Family child care (FCC) refers to regulated (licensed, certified, or registered) HBCC. Family, friend, and neighbor (FFN) care refers to HBCC that is legally exempt from licensing or other regulation, whether paid or unpaid. FFN care includes care given by grandparents, other relatives, and non-relatives. Home-based child care (HBCC) providers are a heterogeneous population of providers who offer care and education to children in their own or the child’s home. (Although we use “HBCC” throughout the report, we recognize the role providers play both caring for and educating children.) Providers’ HBCC status is fluid, and individuals’ roles may change—those who care for a few children who are related to them, whether with or without pay; those who offer care as a professional occupation and a business; those who care for children over many years; and those who care for children sporadically in response to changing family needs. We assume a variety of factors influence these patterns, which may shift over time.

    1. only about 1% of carbon atoms are C-13. These are the only ones picked up by this form of NMR. If you had a single molecule of ethanol, then the chances are only about 1 in 50 of there being one C-13 atom in it, and only about 1 in 10,000 of both being C-13. But you have got to remember that you will be working with a sample containing huge numbers of molecules. The instrument can pick up the magnetic effect of the C-13 nuclei in the carbon of the CH3 group and the carbon of the CH2 group even if they are in separate molecules. There's no need for them to be in the same one.

      the author believe that even though the percentage of C-13 is low, but its NMR signal can be captured.

    1. violencia de género

      «Todo acto de violencia sexista que tiene como resultado posible o real un daño físico, sexual o psíquico, incluidas las amenazas, la coerción o la privación arbitraria de libertad, ya sea que ocurra en la vida pública o en la privada».

    2. Esa “formación” del hombre, que lo conduce a una estructura de la personalidad de tipo psicopático

      No existe un perfil único de maltratador. Tampoco se trata de hombres agresivos ni de psicópatas. Nuestro estudio pone en cuestión los estereotipos relacionados hasta ahora con la conducta y los rasgos del maltratador, como puede ser el consumo de sustancias tóxicas y de alcohol, la vivencia de experiencias traumáticas en la edad infantil o los problemas psíquicos. En este último aspecto, los datos del patrón de personalidad de un grupo de maltratadores basados en el inventario clínico multiaxial Millon-II señalan a la compulsividad como rasgo más destacado de estas personas; no obstante, el percentil no supera el grado de normalidad, por lo que se descarta la posibilidad de una psicopatología.

    2. Food and Drug Administration

      Important term to understand - What do they do, are they part of the government, how do they regulate things?


      I have heard this term used a lot in the last four years. Even when I was unsure what the word precisely meant, I understood it to have negative connotations. OED defines complicity as, "the state of being involved with others in an illegal activity or wrongdoing." If Miller is using the term in this way than that's a pretty risky way to title his piece. It implies that the structure of academia is corrupted.

    1. So for each word, we create a Query vector, a Key vector, and a Value vector. These vectors are created by multiplying the embedding by three matrices that we trained during the training process.
    1. I'm going to try provide an English text example. The following is based solely on my intuitive understanding of the paper 'Attention is all you need'.

      This is also good

    2. For the word q that your eyes see in the given sentence, what is the most related word k in the sentence to understand what q is about?
    3. So basically: q = the vector representing a word K and V = your memory, thus all the words that have been generated before. Note that K and V can be the same (but don't have to). So what you do with attention is that you take your current query (word in most cases) and look in your memory for similar keys. To come up with a distribution of relevant words, the softmax function is then used.
    1. paradigmatic

      I was not sure what this term meant in this context. After looking the term up on google, the definition that seems to fit is the denotation of the relationship between a set of linguistic items that form mutually exclusive choices in particular syntactic roles.

    1. So, what problem is blockchain solving for identity if PII is not being stored on the ledger? The short answer is that blockchain provides a transparent, immutable, reliable and auditable way to address the seamless and secure exchange of cryptographic keys. To better understand this position, let us explore some foundational concepts.

      What problem is blockchain solving in the SSI stack?

      It is an immutable (often permissionless) and auditable way to address the seamless and secure exchange of cryptographic keys.

    1. Moreover, “[r]elations of power are not in a position of exteriority with respect to other types of relationships (economic processes, knowledge rela­tionships, sexual relations), but are immanent in the latter.” Such claims played some role in the rise of a mode of analysis that vastly expands the range of what can be treated as political.

      power is everywhere; in every relationship; this is why the range of what is "political" is actually quite vast

    1. The key phrase here is “children of a grid container.” The specification defines the creation of a grid on the parent element, which child items can be positioned into. It doesn’t define any styling of that grid, not even going as far as to implement something like the column-rule property we have in Multi-column Layout. We style the child items, and not the grid itself, which leaves us needing to have an element of some sort to apply that style to.

    1. Key learnings from this guideYour goal is not to foster the writing habit. Your goal is to fall so in love with ideas that you can’t not write about them. Find your objective and your motivation.Don't fully think through your ideas before writing. It's inefficient. The best way to think is by writing. It compels your brain to connect the dots.Avoid guessing what readers want. Instead, be a proxy: Selfishly entertain and surprise yourself, and you'll entertain and surprise many of them too.Your writing is clear once your thoughts are self-evident.Your writing is succinct once everything unimportant is removed.Your writing is intriguing once the average reader effortlessly makes it to the end. A hook, peak, and satisfying ending are your trifecta of intrigue.Treat feedback as a science. Measure your scores and iterate. Remember that the best feedback often comes from you with fresh eyes.Rewriting your thoughts to be clear, succinct, and intriguing is a lot of work. You won't love writing until you find a way to love rewriting. Make a game out of it.

    1. Most simple example: <script> import ChildComponent from './Child.svelte'; </script> <style> .class-to-add { background-color: tomato; } </style> <ChildComponent class="class-to-add" /> ...compiles to CSS without the class-to-add declaration, as svelte currently does not recognize the class name as being used. I'd expect class-to-add is bundled with all nested style declarations class-to-add is passed to ChildComponent as class-to-add svelte-HASH This looks like a bug / missing feature to me.
