kandi X-RAY | superpower Summary

superpower is a C# library typically used in Utilities, Parser, Nodejs applications. superpower has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

The job of a parser is to take a sequence of characters as input, and produce a data structure that's easier for a program to analyze, manipulate, or transform. From this point of view, a parser is just a function from string to T - where T might be anything from a simple number, a list of fields in a data format, or the abstract syntax tree of some kind of programming language. Just like other kinds of functions, parsers can be built by hand, from scratch. This is-or-isn't a lot of fun, depending on the complexity of the parser you need to build (and how you plan to spend your next few dozen nights and weekends). Superpower is a library for writing parsers in a declarative style that mirrors the structure of the target grammar. Parsers built with Superpower are fast, robust, and report precise and informative errors when invalid input is encountered.

            How is ETCD a highly available system, even though it uses Raft which is a CP algorithm?
            Asked 2021-Dec-16 at 10:38

            This is from Kubernetes documentation:

            Consistent and highly-available key value store used as Kubernetes' backing store for all cluster data.

            Does Kubernetes have a separate mechanism internally to make ETCD more available? or does ETCD use, let's say, a modified version of Raft that allows this superpower?

            ...

            ANSWER

            Answered 2021-Dec-15 at 11:59

            When it comes to going into etcd details, it is best to use the official etcd documentation:

            etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure, even in the leader node.

            There is no mention here that this is high-availability. As for the fault tolerance, you will find a very good paragraph on this topic here:

            An etcd cluster operates so long as a member quorum can be established. If quorum is lost through transient network failures (e.g., partitions), etcd automatically and safely resumes once the network recovers and restores quorum; Raft enforces cluster consistency. For power loss, etcd persists the Raft log to disk; etcd replays the log to the point of failure and resumes cluster participation. For permanent hardware failure, the node may be removed from the cluster through runtime reconfiguration.

            It is recommended to have an odd number of members in a cluster. An odd-size cluster tolerates the same number of failures as an even-size cluster but with fewer nodes.

            You can also find very good article about understanding etcd:

            Etcd is a strongly consistent system. It provides Linearizable reads and writes, and Serializable isolation for transactions. Expressed more specifically, in terms of the PACELC theorem, an extension of the ideas expressed in the CAP theorem, it is a CP/EC system. It optimizes for consistency over latency in normal situations and consistency over availability in the case of a partition.

            Difficulty getting functions to work in my Javascript class
            Asked 2021-Aug-06 at 04:13

            Clearly, a new developer! Thank you for replying in advance, I know the answer must be really simple but I have been stuck for an hour.

            This exercise asks to create a class and then asks to change some of the dynamic values using class methods/functions. I am not able to get my values to change when I call the function.

            Here are the directions for the exercise, followed by my code, sorry that my work looks so rudimentary!

            These are the directions:
            // Create a new class called SuperHero
            // - Your class should have the following DYNAMIC values
            // - name
            // - superpower
            // - age
            // - Your class should have the following STATIC values
            // - archNemesis, assigned to "The Syntax Error"
            // - powerLevel = 100
            // - energyLevel = 50
            //Where I start having issues is here:
            // - Create the following class methods
            // - sayName, should print the hero's name to the console
            // - maximizeEnergy, should update the energyLevel to 1000
            // - gainPower, should take an argument of a number and INCREASE the powerLevel
            //by that number

            Turns out the slowdown is being caused because the arrays being multiplied shared the same memory, and that multiplying the array by 1 created a separate array in memory.

            Blazor and the Superpowered Web Audio SDK, how to return the arrayBuffer to C#
            Asked 2021-Jul-15 at 20:12

            First of all, apologies for such an open question. I think this question comes from a lack of understanding of WASM and the nature of JSInterop in .Net.

            I just wanted to reach out to anyone who has used the Superpowered Web Audio SDK with Blazor and find out how they have used it as I am struggling with JSInterop, and I feel like I am making things harder by not using a Javascript based framework.

            Answered 2021-Jul-01 at 05:58

            There really isn’t any good reason this is allowed: it’s just that passing the address of the (non-constexpr) local variables as this to a member function is not considered in the rules for constant expressions. It’s even permitted to use this in the function called, but you can’t use any of the (non-static) member variables of the class unless they really were initialized as constants. Of course, these size functions don’t need to do so even if they aren’t actually static.

            What’s really confusing is that this permission doesn’t extend to references: using them is considered a read of the effective pointer value, and that must separately be a constant. There are active proposals to allow such usage under the same inevitable restrictions on using the member variables of such an “unknown object”.

            How to append a string onto innerText of a Number in JavaScript for an animated counter
            Asked 2021-May-07 at 09:48

            I've built a ticker/counter animation with basic HTML, CSS and JavaScript and it is working well. This is for a website to show how performance and cashflow has improved when using a service so where I currently have it working and counting up to my target number, I want to append a string onto the end of these targets at the end so instead of (for example), the final target showing 35, I want it to show '35%' or for another element, '2.5x'.

            I essentially want to append either a '%' onto the end if its a whole number, and if its a decimal, I want to append a 'x'.

            The problem I'm having is that when I try at the end to append one of these strings onto my counter, it ruins everything and just keeps returning 0.01% instead of my target number which is 35, 70, 20 etc.

            If I try to add counter.innerText = Math.ceil(count + inc) + '%' for instance, it breaks everything! I've tried to add .toString() to the end too, and then append the '%' but again the same.

            These are my files, I'm sure I'm making a silly mistake somewhere so any help would be greatly appreciated!
