    1. This is probably confusing because the "host" in --network=host does not mean host as in the underlying runner host / 'baremetal' system. To understand what is happening here, we must first understand how the docker:dind service works. When you use the service docker:dind to power docker commands from your build job, you are running containers 'on' the docker:dind service; it is the docker daemon. When you provide the --host option to docker run it refers to the host network of the daemon I.E. the docker:dind container, not the underlying system host.

      explanation - evolutionary biology - neo-darwinian mistake - view of epigenetic inheritance - Neo-darwinians believe that epigenetic inheritance is only short lived. - However, the Noble brothers contend that if the changes in the environment last for many generations, - the epigenetic change can exceed a threshold and become permanently assimilated into the genome - Such a threshold is plausible because without it, a permanent change encoded into the genome would be maladaptive if the environmental change reverted back to the previous state

    1. Instance methods Instances of Models are documents. Documents have many of their own built-in instance methods. We may also define our own custom document instance methods. // define a schema const animalSchema = new Schema({ name: String, type: String }, { // Assign a function to the "methods" object of our animalSchema through schema options. // By following this approach, there is no need to create a separate TS type to define the type of the instance functions. methods: { findSimilarTypes(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); } } }); // Or, assign a function to the "methods" object of our animalSchema animalSchema.methods.findSimilarTypes = function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); }; Now all of our animal instances have a findSimilarTypes method available to them. const Animal = mongoose.model('Animal', animalSchema); const dog = new Animal({ type: 'dog' }); dog.findSimilarTypes((err, dogs) => { console.log(dogs); // woof }); Overwriting a default mongoose document method may lead to unpredictable results. See this for more details. The example above uses the Schema.methods object directly to save an instance method. You can also use the Schema.method() helper as described here. Do not declare methods using ES6 arrow functions (=>). Arrow functions explicitly prevent binding this, so your method will not have access to the document and the above examples will not work.

      Certainly! Let's break down the provided code snippets:

      1. What is it and why is it used?

      In Mongoose, a schema is a blueprint for defining the structure of documents within a collection. When you define a schema, you can also attach methods to it. These methods become instance methods, meaning they are available on the individual documents (instances) created from that schema.

      Instance methods are useful for encapsulating functionality related to a specific document or model instance. They allow you to define custom behavior that can be executed on a specific document. In the given example, the findSimilarTypes method is added to instances of the Animal model, making it easy to find other animals of the same type.

      2. Syntax:

      Using methods object directly in the schema options:

      javascript const animalSchema = new Schema( { name: String, type: String }, { methods: { findSimilarTypes(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); } } } );

      Using methods object directly in the schema:

      javascript animalSchema.methods.findSimilarTypes = function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); };

      Using Schema.method() helper:

      javascript animalSchema.method('findSimilarTypes', function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); });

      3. Explanation in Simple Words with Examples:

      Why it's Used:

      Imagine you have a collection of animals in your database, and you want to find other animals of the same type. Instead of writing the same logic repeatedly, you can define a method that can be called on each animal instance to find similar types. This helps in keeping your code DRY (Don't Repeat Yourself) and makes it easier to maintain.

      Example:

      ```javascript const mongoose = require('mongoose'); const { Schema } = mongoose;

      // Define a schema with a custom instance method const animalSchema = new Schema({ name: String, type: String });

      // Add a custom instance method to find similar types animalSchema.methods.findSimilarTypes = function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); };

      // Create the Animal model using the schema const Animal = mongoose.model('Animal', animalSchema);

      // Create an instance of Animal const dog = new Animal({ type: 'dog', name: 'Buddy' });

      // Use the custom method to find similar types dog.findSimilarTypes((err, similarAnimals) => { console.log(similarAnimals); }); ```

      In this example, findSimilarTypes is a custom instance method added to the Animal schema. When you create an instance of the Animal model (e.g., a dog), you can then call findSimilarTypes on that instance to find other animals with the same type. The method uses the this.type property, which refers to the type of the current animal instance. This allows you to easily reuse the logic for finding similar types across different instances of the Animal model.

      Certainly! Let's go through each part and explain it in simple terms: ### 1. `this` in Mongoose: - **What is `this`?** In JavaScript, `this` refers to the current context or object. In Mongoose, particularly within methods and middleware functions, `this` represents the instance (document) the function is currently operating on. - **Why is it used?** `this` is used to access and modify the properties of the current document. For example, in a Mongoose method, `this` allows you to refer to the fields of the specific document the method is called on. ### 2. Example: Let's use the `userSchema.pre("save", ...)`, which is a Mongoose middleware, as an example: ```javascript userSchema.pre("save", async function (next) { if (!this.isModified("password")) { next(); } else { this.password = await bcrypt.hash(this.password, 10); next(); } }); ``` - **Explanation in Simple Words:** - Imagine you have a system where users can sign up and set their password. - Before saving a new user to the database, you want to ensure that the password is securely encrypted (hashed) using a library like `bcrypt`. - The `userSchema.pre("save", ...)` is a special function that runs automatically before saving a user to the database. - In this function: - `this.isModified("password")`: Checks if the password field of the current user has been changed. - If the password is not modified, it means the user is not updating their password, so it just moves on to the next operation (saving the user). - If the password is modified, it means a new password is set or the existing one is changed. In this case, it uses `bcrypt.hash` to encrypt (hash) the password before saving it to the database. - The use of `this` here is crucial because it allows you to refer to the specific user document that's being saved. It ensures that the correct password is hashed for the current user being processed. In summary, `this` in Mongoose is a way to refer to the current document or instance, and it's commonly used to access and modify the properties of that document, especially in middleware functions like the one demonstrated here for password encryption before saving to the database.

    1. because the value isn't there yet. A promise is just a marker that it will be available at some point in the future. You cannot convert asynchronous code to synchronous, though. If you order a pizza, you get a receipt that tells you that you will have a pizza at some point in the future. You cannot treat that receipt as the pizza itself, though. When you get your number called you can "resolve" that receipt to a pizza. But what you're describing is trying to eat the receipt.

        • The first principle determined by Husserl (quoted in Villanueva, 2014) to approach subjectivity,is:the epoché, placing in parentheses the supposition of the natural attitude, present in our habitual rapport to the world.
        • For example, this natural attitude is found in the sciences
        • It is the acknowledgement of the world as something given or its facts, as a reality itself, existing beyond the consciousness that thinks, values or feels them.
        • In other words, "the epoché refers to the elimination of everything that limits us from perceiving things as such, since the natural attitude, due to its objective nature, prevents us from doing so.
        • To apply the epoché, refers, to abstain or to do without" (Villanueva, 2014, p.220).
        • This principle
          • does not imply questioning the world as if it existed,
          • nor does it reduce it to the thought of the subject.
        • On the contrary, it tries to stop thinking under these terms, with the objective of being able to observe the life of the consciousness that is behind the objects understood as given things: to approach how this represents them, the meaning it assumes for it.
        • In short, what original sense they possess or how they become objects of consciousness.

        • Robinson contextualizes the empiricist project and gap thereof, as one of the 4 goals of Kant's Critique of Pure Reason.
        • Robinson informally calls this the "Locke" problem, after one of the founders of the Empiricist school, John Locke.
        • Robinson also alludes to a Thomas Reed approach to realism that contends that we don't experience reality MEDIATELY, but IMMEDIATELY, thereby eliminating the gap problem altogether.
        • It's interesting to see how modern biology views the empericist's knowledge gap, especially form the perspective of the Umwelt and Sensory Ecology

    1. Based on these studies, we initi-ated an effort to optimize novel mGlu5 PAMs that potentiatemGlu 5 -mediated Gaq signaling and calcium mobilization

      Statement on what they did. They are trying to optimize a novel PAM that well potentiate mGlu5 mediated Galpha-q signaling and Ca2+ mobilization. What they DONT want is a PAM that potentiates coupling of mGlu5 to modulation of NDMAr currents.

      Why dont they want this? The key point here is that they are trying to selectively enhance certain aspects of mGlu5 receptor function while avoiding the enhancement of its interaction with NMDAR currents. This suggests that there may be some undesired side effects or interactions when mGlu5 and NMDAR currents are potentiated together. By designing PAMs that specifically target one aspect of mGlu5 function (GaQ signaling and calcium mobilization) without affecting another (NMDAR currents), they hope to achieve a more targeted and potentially safer therapeutic effect.

But "@ymail.com" honestly looks more appealing to me than either of the "yahoo" iterations.

    1. ocates in about the nineteenth century a shift in European thought fromviewing same-sex sexuality as a matter of prohibited and isolated genitalacts (acts to which, in that view, anyone might be liable who did not havetheir appetites in general under close control) to viewing it as a function ofstable definitions of identity (so that one's personality structure mightmark one as a homosexual, even, perhaps, in the absence of any genitalactivity at all). T hus, according to Alan Bray, "To talk of an individual [inthe Renaissance] as being or not being 'a homosexual' is an anachronismand ruinously misleading,"14 whereas th�period stretching roughly '2._e_tween Wilde and Proust was prodigally productive of atte�E_ts to name,explain, and define.this new kind of creature, the homosexual person-aproject SO urgent tfiat It spawne in its rage of distinction- ane�en ne�rcategory, that of the heterosexual persoriJ 5

      Foucault and other historians point out a change in European thinking during the 19th century regarding same-sex sexuality. Previously, it was seen as a matter of prohibited acts, where anyone who didn't have strict control over their desires could engage in such acts. However, a shift occurred where same-sex sexuality came to be seen as part of a person's identity. This means that one's personality traits or characteristics could identify them as a homosexual, even if they didn't engage in any sexual activity. In contrast, during the period from Wilde to Proust, there was a strong desire to name, explain, and define this new category of individuals, the homosexual person. This urgency to distinguish and define led to the emergence of another category, that of the heterosexual person.

    1. It seems like the neuron basically adds the embedding of “ an” to the residual stream, which increases the output probability for “ an” since the unembedding step consists of taking the dot product of the final residual with each token2.

    1. The variable x initially has the type unknown: the type of all values. The predicate typeof x === "number" extracts dynamic information about the value bound to x, but the type-checker can exploit this information for static reasoning. In the body of the if statement the predicate is assumed to be true; therefore, it must be the case the value bound to x is a number. TypeScript exploits this information and narrows the type of x from unknown to number in the body of if statement.

    1. because most languages treat strings as immutable, which helps ensure you don't accidentally modify them and can improve performance. Fewer state changes in a program mean less complexity. It's better to opt-in to mutability after careful consideration rather than making everything mutable by default. What is immutability and why should I worry about it? may help.
    1. One of the main features of the high level architecture of a transformer is that each layer adds its results into what we call the “residual stream.”Constructing models with a residual stream traces back to early work by the Schmidhuber group, such as highway networks  and LSTMs, which have found significant modern success in the more recent residual network architecture . In transformers, the residual stream vectors are often called the “embedding.” We prefer the residual stream terminology, both because it emphasizes the residual nature (which we believe to be important) and also because we believe the residual stream often dedicates subspaces to tokens other than the present token, breaking the intuitions the embedding terminology suggests. The residual stream is simply the sum of the output of all the previous layers and the original embedding. We generally think of the residual stream as a communication channel, since it doesn't do any processing itself and all layers communicate through it.
    2. A transformer starts with a token embedding, followed by a series of “residual blocks”, and finally a token unembedding. Each residual block consists of an attention layer, followed by an MLP layer. Both the attention and MLP layers each “read” their input from the residual stream (by performing a linear projection), and then “write” their result to the residual stream by adding a linear projection back in. Each attention layer consists of multiple heads, which operate in parallel.
    1. CREATE INDEX Statement

      ABOUT INDEXES *indexes can make queries faster, much like looking for a term in the index of a textbook instead of skimming through all the pages in the book to find all the references to the term. However, indexes take storage space and the DBMS must maintain the index as rows are inserted, updated and deleted in the table.

    2. SELECT HORSE_ID, SUM(PURSE), COUNT(*) AS NUM_RACES FROM RACE_RESULT GROUP BY HORSE_ID;

      okay what i'm missing here is that the race_result table I think groups rows by race, not by horse. So each horse can have multiple races.

      The above statements asks the dbms to find each race (row) with a specific horse_id, and then average certain column values from all the rows corresponding to the same horse_id. The average is then to be output as a new row containing a single horse id, the sum of that horses earnings across all race rows, the COUNT(*) statement is then used to count how many rows in the horse table had a specific horse id.So really the query is requesting a table with

      horse_id | (earnings sum from race_result rows with horse_id) | (number of race result rows featuring horse_id)

    3. SUM(PURSE), COUNT(*) AS NUM_RACES

      IMPORTANT!! : The group by clause is needed here because unlike in previous queries, we aren't simply taking a value in a prexisting table and adding it to a smaller table using the SELECT clause. We are using functions to create entirely new values. These values dont exist as part of the table, they kinda just float. Because these are floating unindexed values, the group by clause is needed to indicate how these new values should be presented in the output table for the query

    4. An inner join is best thought of as an exclusive join because the result set includes only rows where matches were found in both tables (unmatched rows are excluded from the results)

      TLDR inner join = exclusive to matches in both tables * Any row from the key table which has a value that is omitted from the key column (Horse table has key columns of sire_id and dam_id) is exlcuded from the final result. So if horse_id_x has a null value for its sire or dam id, then any information about the row corresponding to horse_id_X is entirely ommitted from the final result of the joined table.

    1. But anti- spam software often fetches all resources in mail header fields automatically, without any action by the user, and there is no mechanical way for a sender to tell whether a request was made automatically by anti-spam software or manually requested by a user. To prevent accidental unsubscriptions, senders return landing pages with a confirmation step to finish the unsubscribe request. A live user would recognize and act on this confirmation step, but an automated system would not. That makes the unsubscription process more complex than a single click.

    1. For example, if I make an application (Client) that allows a user (Resource Owner) to make notes and save them as a repo in their GitHub account (Resource Server), then my application will need to access their GitHub data. It's not secure for the user to directly supply their GitHub username and password to my application and grant full access to the entire account. Instead, using OAuth 2.0, they can go through an authorization flow that will grant limited access to some resources based on a scope, and I will never have access to any other data or their password.

    1. The problem is that the caller may write yield instead of block.call. The code I have given is possible caller's code. Extended method definition in my library can be simplified to my code above. Client provides block passed to define_method (body of a method), so he/she can write there anything. Especially yield. I can write in documentation that yield simply does not work, but I am trying to avoid that, and make my library 100% compatible with Ruby (alow to use any language syntax, not only a subset).

The "rails server" is not an application server by itself, but just a small wrapper that launches your application in an application server. This is why people do not use "rails server" in production. They use an application server – such as Passenger – directly. "rails server" uses Puma by default as of Rails 5.

    1. Such schemas cannot easily be refactored without removing the benefits of sharing. Refactoring would require forking a local copy, which for schemas intended to be treated as an opaque validation interface with internal details that may change, eliminates the benefit of referencing a separately maintained schema in the first place.
    2. This means that when considering the "unevaluatedProperties": false in the root schema, "wheels" has not been evaluated, so unevaluatedProperties applies to it, and therefore validation fails because the false subschema fails by definition against any instance.

    1. JSON Schema allows for additionalProperties both a boolean or an object value. true is interpreted as "additional properties follow no restrictions", false means "no additional restrictions", and an object is interpreted as a JSON schema applied to the property values (the empty object is thus equivalent to true).
    1. Now, the progression of NLP, as discussed, tells a story. We begin with tokens and then build representations of these tokens. We use these representations to find similarities between tokens and embed them in a high-dimensional space. The same embeddings are also passed into sequential models that can process sequential data. Those models are used to build context and, through an ingenious way, attend to parts of the input sentence that are useful to the output sentence in translation.

    1. The major issue with much of the data that can be downloaded from web portals or through APIs is that they come without context or metadata. If you are lucky you might get a paragraph about where the data are from or a data dictionary that describes what each column in a particular spreadsheet means. But more often than not, you get something that looks like figure 6.3.

      I think that the reason behind data's lack of context is the reluctance in making extra column for data's description and the inconsiderate and misleading vision that those in technologies hold when they put forth that data should be clean and concise.

      I encountered the insufficient provision of data multiple times and I found it extremely inconvenient when trying to use downloaded online reports and attached them to my work experiences as a way to illustrate the efficient changes in driving audiences for a social media platform (Facebook). I used to help run an facebook page for a student organization. After being done with the role, I went to the "Insights" section of Facebook, hoping to download the report of increases in Page Likes, Visits, and Interactions during the period that I was an admin of the page. It took me several glitches to download the report (because it was a year-long term). When the pdf file was ready to be viewed, I was surprised, because they did not mention the years I was working, the name of the student organization, and other categorizations that should have been highlighted. Apparently, it's not hard to include the years or even the name because they were included in the filter when I wanted to extract certain part of the report and because it was the source where they took the data from, respectively. This laziness in showing competent data for analysis was desperate, and I had to add extra analysis to it. Even after I finished with the "extra work", I started to question to validity of the report I was downloading. Would it be trustworthy anymore, because without my clarification, no analysis could be made even by a person involved in data science field. Even if they could, it would take them a while to collect other external information before making clear of the data presented to them.

      Understanding and constantly being bothered by this ongoing problem gives me justification to call for a more thorough data translation and presentation process. More questions should be raised and answered regarding what might a user wonder about this dataset when encountering it.

    1. The dominant idea is one of attention, by which a representation at a position is computed as a weighted combination of representations from other positions. A common self-supervision objective in a transformer model is to mask out occasional words in a text. The model works out what word used to be there. It does this by calculating from each word position (including mask positions) vectors that represent a query, key, and value at that position. The query at a position is compared with the value at every position to calculate how much attention to pay to each position; based on this, a weighted average of the values at all positions is calculated. This operation is repeated many times at each level of the transformer neural net, and the resulting value is further manipulated through a fully connected neural net layer and through use of normalization layers and residual connections to produce a new vector for each word. This whole process is repeated many times, giving extra layers of depth to the transformer neural net. At the end, the representation above a mask position should capture the word that was there in the original text: for instance, committee as illustrated in Figure 1.
    1. This trick of using a one-hot vector to pull out a particular row of a matrix is at the core of how transformers work.

    1. The ORDER BY clause can only be applied after the DISTINCT has been applied. Since only the fields in the SELECT statement are taken into consideration for the DISTINCT operations, those are the only fields may be used in the ORDER BY.

    1. The backslash character does not concatenate any strings. It prevents the line-break from meaning that those two lines are different statements. Think of the backslash as the opposite of the semicolon. The semicolon lets two statements occupy one line; the backslash lets one statement occupy two lines.
    1. Think the mere existence of a file is effectively like writing a require call for them, which is executed on demand (autoload) or upfront (eager load).
    1. Example 1. For example, suppose that the input volume has size [32x32x3], (e.g. an RGB CIFAR-10 image). If the receptive field (or the filter size) is 5x5, then each neuron in the Conv Layer will have weights to a [5x5x3] region in the input volume, for a total of 5*5*3 = 75 weights (and +1 bias parameter). Notice that the extent of the connectivity along the depth axis must be 3, since this is the depth of the input volume. Example 2. Suppose an input volume had size [16x16x20]. Then using an example receptive field size of 3x3, every neuron in the Conv Layer would now have a total of 3*3*20 = 180 connections to the input volume. Notice that, again, the connectivity is local in 2D space (e.g. 3x3), but full along the input depth (20).

      These two examples are the first two layers of Andrej Karpathy's wonderful working ConvNetJS CIFAR-10 demo here

    1. Here the lower level layers are frozen and are not trained, only the new classification head will update itself to learn from the features provided from the pre-trained chopped up model on the left.

    1. FORBIDDEN: Status code (403) indicating the server understood the request but refused to fulfill it. User/agent known by the server but has insufficient credentials. Repeating request will not work, unless credentials changed, which is very unlikely in a short time span.
    2. This may be because it is known that no level of authentication is sufficient (for instance because of an IP blacklist), but it may be because the user is already authenticated and does not have authority.
    3. There's a problem with 401 Unauthorized, the HTTP status code for authentication errors. And that’s just it: it’s for authentication, not authorization. Receiving a 401 response is the server telling you, “you aren’t authenticated–either not authenticated at all or authenticated incorrectly–but please reauthenticate and try again.” To help you out, it will always include a WWW-Authenticate header that describes how to authenticate.
    4. So, for authorization I use the 403 Forbidden response. It’s permanent, it’s tied to my application logic, and it’s a more concrete response than a 401. Receiving a 403 response is the server telling you, “I’m sorry. I know who you are–I believe who you say you are–but you just don’t have permission to access this resource. Maybe if you ask the system administrator nicely, you’ll get permission. But please don’t bother me again until your predicament changes.”
    5. UNAUTHORIZED: Status code (401) indicating that the request requires authentication, usually this means user needs to be logged-in (session). User/agent unknown by the server. Can repeat with other credentials. NOTE: This is confusing as this should have been named 'unauthenticated' instead of 'unauthorized'.
    6. +----------------------- | RESOURCE EXISTS ? (if private it is often checked AFTER auth check) +----------------------- | | NO | v YES v +----------------------- 404 | IS LOGGED-IN ?

(permission, authorized, ...) or +----------------------- redirect | | to login NO | | YES | | v v 403 OK 200, redirect, ...

    1. greedy search (i.e., at each step find the next most influentialattribute for this image, given the subset of attributes selectedso far; halt once the classifier has flipped its classification).We can then visualize the effect of modifying this subset.We refer to this as Subset selection
    2. The simplest is to iterate over StylExattributes, calculate the effect of changing each on the classi-fier output for this image, and return the top-k of these. Wecan then visualize the resulting k modified images. We referto this strategy as Independent selection.
    3. counterfactual example,i.e., visualizing how manipulation of this attribute (style coordinate) affects the classifier output probability.
    1. The intended behavior for the code snippet above is to reactively update b when a changes allows b temporarily go "out-of-sync" of a when calling update, setting b to 42 in this case, b is not always a * 2 however, if a changes again, b will be updated back to a * 2, instead of staying at 42
    1. When you give an element a width of 100% in CSS, you’re basically saying “Make this element’s content area exactly equal to the explicit width of its parent — but only if its parent has an explicit width.” So, if you have a parent container that’s 400px wide, a child element given a width of 100% will also be 400px wide, and will still be subject to margins, paddings, and borders — on top of the 100% width setting.
    1. When you initially logon with OAuth2, you will be redirect to Google’s sign-in page,. Once you have signed in, Google issues you a special OAuth2 token which is saved in Thunderbird and can be seen in the same place as passwords. So when you next logon to gmail, it is using that unique OAuth ID instead of password.

    1. The selective-second-order-with-skips model is a useful way to think about what transformers do, at least in the decoder side. It captures, to a first approximation, what generative language models like OpenAI's GPT-3 are doing.
    1. In your Svelte component, you can then use your store with the special $ prefix syntax, to access the value of the store ('cause the temperature variable is a reference to the store itself, it's just a mean to our end, the result we need is the value):
    2. Stores are essentially some kind of simplified streams (or Observable as they're called in ES), that is they represent a value over time.
    3. Stores are the idiomatic Svelte way when you need to import "reactivity" from your normal JS sources.
    1. It might be confusing that a union of types appears to have the intersection of those types’ properties.

    1. Calling a software convention "pretty 90s" somewhat undermines your position. Quite a lot of well-designed software components are older than that. If something is problematic, it would be more useful to argue its faults. When someone cites age to justify change, I usually find that they're inexperienced and don't fully understand the issues or how their proposed change would impact other people.
    1. why is Session not assignable to WithAdditionalParams<Session>? Well, the type WithAdditionalParams<Session> is a subtype of Session with includes a string index signature whose properties are of type unknown. (This is what Record<string, unknown> means.) Since Session does not have an index signature, the compiler does not consider WithAdditionalParams<Session> assignable to Session.

      on n'a que des bougies où l'ouverture est plus haute que la fermeture, et la key reversal bar est celle où l'ouvereture est plus basse que le fermeture (d'où le nom de reversal bar, car l'ouverture se trouve "à la place" de la fermeture !)

    17. We shall now look at various generic bullish and bearish formations

      En bourse, sur une valeur ou un indice, on parle de « gap » quand le cours d'ouverture est plus haut, ou plus bas, que tous les cours du jour de cotation précédent. Si la valeur d'ouverture est inférieure à la valeur la plus faible atteinte le précédent jour de cotation, on parle de « gap baissier ». Si la valeur d'ouverture est supérieure à la valeur la plus élevée atteinte le précédent jour de cotation, on parle de « gap haussier ».

      Par exemple, si une valeur possède un cours compris entre 10 et 12 un jour donné, si le jour de cotation suivant la valeur ouvre avec un cours de 9 on parlera de gap baissier, si elle ouvre avec un cours de 13 on parlera d'un gap haussier.

      Une règle d'analyse technique affirme que les gaps sont comblés. C'est-à-dire que, en cas de gap baissier, la valeur remontera au moins à la valeur la plus faible atteinte le jour de cotation précédent le gap. Dans notre exemple de gap baissier, il s'agirait de 10.

      De même, la règle affirme qu'en cas de gap haussier, la valeur baissera en séance au moins à la valeur la plus haute atteinte le jour de cotation précédent le gap. Dans notre exemple de gap haussier il s'agirait de 12.

      Il existe un certain nombre de cas de gap qui n'ont jamais été comblés et pour lesquels le comblement est assez improbable

      Normalement, dans la figure avec le support 1, on aurait dû casser ce support car on avait du volume pour confirmer la downtrend. Similairement pour la resistance 1. Low volume in the two lower charts are less reliable since it is mainly due to a lack of interest of the market participants.

    25. ing limits the losses in either scenario by allocating a fixed percentage of original capital to narrow stops and a fixed percentage of current capital for stopsizes that exceed a fixed threshold size. The procedure for determining the proportional tradesize is as follows: 1. Do a backtest to find the average stopsize for at least 300 to 500 trades (if possible). 2. Calculate the two standard deviation value based on all the stopsizes in the sample. 3. Add this two‐standard deviation value to the average stopsize (this represents the proportional stopsize). 4. Determine the maximum percentage of current capital to risk for each trade and calculate its corresponding dollar value risk per trade. 5. Divide this dollar value risk per trade by the proportional stopsize (this repre-sents your proportional tradesize).Therefore, the trader would initiate trades based on the proportional trade-size for all trades where the stopsize is at or below the proportional stopsize. For stopsizes that exceed the proportional stopsize, calculate the tradesize by sim-ply dividing the maximum dollar value risk per trade by the stopsize. The term proportional refers to the percentage risk allocated per trade that is initiated for entries with stopsizes at or below the proportional stopsize. For such entries, the percentage of risk will vary proportionally with the stopsize, where the maxi-mum risk will always be capped at the maximum percentage risk per trade. For a more detailed description of the tradesizing issues that plague traders, refer to Chapter 28

    27. Completion of the Average Period Range: One of the most reliable charac-teristics of price activity lies with its average period range, with the period being any chosen duration of observation. For example, let us assume that the average daily range of a certain FOREX pair is 120 pips per day. This would essentially mean that any price activity beyond this average range in either direction prior to the completion of the trading day will be regarded as a po-tential sign of exhaustion and a reversal may be expected. It is important to note that these averages period ranges may also be associated with underlying wave cycles in the market. Once the average range is breached prematurely, the practitioner begins to look for various signs of a reversal, paying special attention to supportive and resistive confluences. The average period range may be obtained via either of the following approaches: ■ The use of the average true range indicator (ATR) set to a reasonable look-back period on an interval chart of interest. ■ By finding the 2 standard deviation value of bar range over a certain number of periods.The practitioner should conduct a simple backtest to find the most reli-able lookback period for each of the above approaches. Note that with the latter approach, ninety percent of the period ranges will remain below the calculated value, the breach of which represents a greater degree of overex-tension or exhaustion

For example, your load function might make a request to a public URL like https://api.yourapp.com when the user performs a client-side navigation to the respective page, but during SSR it might make sense to hit the API directly (bypassing whatever proxies and load balancers sit between it and the public internet).

    1. When we describe a language as type-checked, we mean that the language won't let you perform operations invalid for the type. Neither statically nor dynamically typed languages will let you multiply strings together, call a number in the place of a function, etc. A language without type checking would let you do all of those things without complaint.
    1. TypeScript is an extension of JavaScript. You can think of it as JavaScript with a few extra features. These features are largely focused on defining the type and shape of JavaScript objects. It requires that you be declarative about the code you're writing and have an understanding of the values your functions, variables, and objects are expecting.While it requires more code, TypeScript is a fantastic means of catching common JavaScript bugs while in development. And for just that reason, it's worth the extra characters.

    2. Webpack's resolve.mainFields option determines which fields in package.json are used to resolve identifiers.

    1. The important thing to understand is that there is no such thing as a class method in Ruby. A class method is really just a singleton method. There is nothing special about class methods. Every object can have singleton methods. We just call them "class methods" when the object is a Class because "singleton method of an instance of Class" is too long and unwieldy.
