            Shorthand object initializer syntax for matching property name
            Asked 2021-Jun-15 at 18:36

            Sometimes I find myself needing to initialize an object with a property that matches the property of another object. When the property name is the same, I want to be able to use shorthand syntax.

            (For the purposes of the examples in this question, I'll just keep the additional properties to a tag: 1 property, and I'll reuse message in subsequent examples as the input/source of the information. I also indicate an extra unwanted property of message because I'm cherry-picking properties and do not intend to just use Object.assign to assign all the properties of message to the result.)

            This is extreme weird behaviour, and I dont really think github and slack are linked together somehow that magically remove APP as soon as its Token got exposed.

            They are, though: https://docs.github.com/en/code-security/secret-security/about-secret-scanning

            Secret scanning is a mechanism to do just that, detect accidentally leaked secrets in GitHub and report them to the affected service. There are 40+ partners already participating in this, including Slack.

            GitHub scans repositories for known types of secrets, to prevent fraudulent use of secrets that were committed accidentally.

            Secret scanning is automatically enabled on public repositories. When you push to a public repository, GitHub scans the content of the commits for secrets. If you switch a private repository to public, GitHub scans the entire repository for secrets.

            Probably intentionally publishing a live token to a public GitHub repo is a not the right approach, I'd recommend using a private repo instead.

            In Blazor serverside can you get hold of circuit specific state in a static context without passing it in?
            Asked 2021-Jun-12 at 12:56

            Ok, a rather specific question which requires additional explanation and context.

            Context

            We are POCing a "try-convert" from a bespoke language to .net core (5 currently) and blazor server. Server because it allows a try-convert scaffolding we can build security concerns round. The details of this are not important. It just explains why we have some constraints which may seem unrealistic under normal circumstances.

            I am fully accepting that "no you can't" or even "no you shouldn't" is the likely outcome. We are exploring possibilities.

            Question

            The concept of a circuit in blazor is a really good fit for the presentation layer. We would like to store information at the scope of the circuit.

            The obvious solution is to use a scoped service in the dependency injection container.

            As far as I understood both your question and the Blazor concepts, the answer to your question is « no ». There is no possibility to retrieve statically the current HTTP context in Blazor. Because you never know if the context is an initial page load or just SignalR communication to update the current page. Here is the manner I save this situation:

            • Create a cascading parameter that is shared by all razor components

            • This cascading parameter is a class with many information coming from initial HTTP request, caught in the _Host.cshtml from the httpContextAccessor.HttpContext

            • This cascading parameter class gets all the methods of my previous static methods.

            • These methods can use the properties of the cascading parameter: RawUrl, UserAgent, ClientIp, …

            This implies hard refactoring work to migrate legacy ASP web sites. But the performances of Blazor are worth it.

            Merging structs in C
            Asked 2021-Jun-11 at 20:56

            Is there a way to combine two structs struct A and struct B into a third struct C in a way that changes to either struct A or struct B, like adding a new field, are automagically reflected in struct C?

            The motivation is that e.g. struct A comes from some library and struct B and is under my control and contains additional data not found in struct A; the purpose of struct C is to access the members of struct A and struct B via a uniform interface represented by struct C.

            QUESTION

            Does it make sense to backpropagate a loss calculated from an earlier layer through the entire network?
            Asked 2021-Jun-09 at 10:56

            Suppose you have a neural network with 2 layers A and B. A gets the network input. A and B are consecutive (A's output is fed into B as input). Both A and B output predictions (prediction1 and prediction2) Picture of the described architecture You calculate a loss (loss1) directly after the first layer (A) with a target (target1). You also calculate a loss after the second layer (loss2) with its own target (target2).

            Does it make sense to use the sum of loss1 and loss2 as the error function and back propagate this loss through the entire network? If so, why is it "allowed" to back propagate loss1 through B even though it has nothing to do with it?

            This question is related to this question https://datascience.stackexchange.com/questions/37022/intuition-importance-of-intermediate-supervision-in-deep-learning but it does not answer my question sufficiently. In my case, A and B are unrelated modules. In the aforementioned question, A and B would be identical. The targets would be the same, too.

            (Additional information) The reason why I'm asking is that I'm trying to understand LCNN (https://github.com/zhou13/lcnn) from this paper. LCNN is made up of an Hourglass backbone, which then gets fed into MultiTask Learner (creates loss1), which in turn gets fed into a LineVectorizer Module (loss2). Both loss1 and loss2 are then summed up here and then back propagated through the entire network here.

            Even though I've visited several deep learning lectures, I didn't know this was "allowed" or makes sense to do. I would have expected to use two loss.backward(), one for each loss. Or is the pytorch computational graph doing something magical here? LCNN converges and outperforms other neural networks which try to solve the same task.

            Yes, It is "allowed" and also makes sense.

            From the question, I believe you have understood most of it so I'm not going to details about why this multi-loss architecture can be useful. I think the main part that has made you confused is why does "loss1" back-propagate through "B"? and the answer is: It doesn't. The fact is that loss1 is calculated using this formula:

            mix-blend-mode with table cell that have position sticky
            Asked 2021-Jun-09 at 06:59

            I have very weird behavior that happens in both Google Chrome and Firefox.

            I have a table with a gradient background that creates zebra stripes. The cells have a white background and I use mix blend mode to hide the cells that are sticky so only one sticky cell that is visible.

            The problem is that when the table cell is sticky, blend mode doesn't work properly and you see multiple cells at once. But if I put div inside the cell and make the div sticky it magically works. Any idea why?

            ANSWER

            Answered 2021-Jun-09 at 06:59

            Refer to the docs:

            A stickily positioned element is an element whose computed position value is sticky. It's treated as relatively positioned until its containing block crosses a specified threshold (such as setting top to value other than auto) within its flow root (or the container it scrolls within), at which point it is treated as "stuck" until meeting the opposite edge of its containing block.

            So your problem is not caused by td or div itself. It's because of their containing block:

            If the position property is static, relative, or sticky, the containing block is formed by the edge of the content box of the nearest ancestor element that is either a block container (such as an inline-block, block, or list-item element) or establishes a formatting context (such as a table container, flex container, grid container, or the block container itself).

            For sticky with the div inside td, it's clear that the containing block is its parent td(because td establishes a formatting context) so each div have its own containing block and will not be stacked.

            For sticky with td, I haven't found any official document about containing block of td, only found this, so I'm not sure it's a tbody, table or the div that wrap the table. The only thing can be sure is all the td sharing the same containing block, that's why it's stacked.

            There are two ways to bind collections when posting forms. One, which is what you are currently doing, is to use a sequential index that starts from 0 and increments by 1 for each element in the collection.

            The other is to use an explicit index, which can be any value which it doesn't need to be sequential. It doesn't even need to be numeric. This approach requires an additional hidden field for each item, named [property].Index which represents index of the item.
