kandi X-RAY | duty Summary

duty is a JavaScript library typically used in Server, Runtime Evironment, Nodejs applications. duty has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i duty' or download it from GitHub, npm.

Simply managing offline jobs shouldn't involve dedicated databases, standalone servers or complex configuration. It should just flow naturally with the rest of the code. Duty is a dumb-simple job queueu implementation that runs in native Javascript and by default, doesn't require any external database. There are other, more elaborate job queue systems for Node js. Kue is a very recommended library, backed by Redis. However, Node lacks a simple job queue system that doesn't require any additional infrastructure to test and play around with, even on local servers.

Try this. Your code was confusing in how it used the array a, but I think this is the gist. Really, you should have told us what you were trying to do here.

QUESTION

Query to Find Adjacent Records in Access 2016

Asked 2021-Jun-11 at 08:36

I have a table with a field called Result that contains values that can be anywhere between 1 and 100.

The table also contains a Date/Time field and is sorted from oldest to newest.

I want to be able to return adjacent records that have a Result of less than 3.

So, I need to first find a record with a Result that is less than 3 then check if the next records also have a Result of less than 3. If they do these records should be returned.

There may be no such adjacent records or there may be multiple records that meet this criteria.

Is this possible?

I've put together a short piece of code that loops the original data, ordered by the date field, and if it finds a result of less than 3, checks the following results until one of them is 3 or more. It adds all of the ID fields to a string, which can then be used as the SQL for a query.

QUESTION

Efficient algorithm to reduce peak power from multiple pwm output?

Asked 2021-Jun-08 at 00:39

I have multiple power mosfet pwm controlled and connected to a single main power supply. Thee pwm signals operate all at the same frequency and their duty factor is determined otherwise and can change frequently. It can can vary between 0 and 100%. My PWM controller allows me to choose On time and off time independently for each signal.

I am looking for an efficient algorithm to determine the on time of each channel in order to minimize the peak power drawn from the power supply.

A trivial example: With 10 mosfet each one with a 10% duty factor the optimal solution will be to turn on each mosfet one at a time in sequence.

Any ideas out there on how to address this problem? Thanks

ANSWER

Answered 2021-Jun-08 at 00:39

Let the pulse width fractions (between 0 and 1) be p₁, ..., p_n. Let s₀ = 0 and s_n = s_n−1 + p_n be the prefix sums. Signal i should turn on at times s_i−1 mod 1 and end at times s_i mod 1.

This algorithm does what you want on the trivial example, since s₀, s₁, ..., s_n−1, s_n = 0, 1/10, ..., 9/10, 0.

For a less trivial example, suppose that we have signals at 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%. Then the pulses look like

ANSWER

Answered 2021-Jun-07 at 12:24

I believe it is better to separate the two ways of launching your jobs. You can use the controller for API-based on-demand job launches, and use the @Scheduled way for a background process that launches jobs on the defined schedule.

That said, you should take into consideration the concurrency policy for your job definitions. For example, what should your system do if a job launch request comes through the API and tries to launch the same job that has been launched by a schedule (which could be running at that time)?. There are other use cases, but those depend on your requirement.

but I cant be able to do that I had tried with 2 blocks of if-else but it doesn't work due to its take if-else synchronously then I tried to calculate the graph and want to put it as a delay but it is not an easy solution

Why is the body and animated background separated (not on top of eachother) on my HTML-website?

Asked 2021-May-20 at 09:48

I'm a student learning HTML and CSS. For a school project we need to make a simple game and I'm currently working on the design of the game lobby.

I wanted to add a moving smoke/fog overlay on top of my background but behind my tables, buttons and everything so I searched for some tutorials and was able to implement this. The only problem I have is that the background with the smoke is underneath the rest of my code. I tried searching for the problem myself but wasn't able to find it.

ANSWER

Answered 2021-May-20 at 09:48

Disclaimer: novice here so take this with a pinch of salt. I've provided a solution below that certainly isn't the most elegant but will help you on your way without altering too much of your code.

We can take the section of class 'fog' out entirely for the time being to simplify things a little.
We then take the div of class 'absolute-bg' and place this immediately below the body, making sure that all of your remaining elements are within this div and therefore (visually) 'on top' of your background.
We then set the 'absolute-bg' class to have a lower z-index than everything else (e.g. -1).
Next, we can take the div of 'fog-container' and give it two simple CSS properties: position: fixed; top: 0;
This removes the element from the Document flow and places it in a fixed position relative to the browser window, in this case, top: 0.
Finally, you want to be able to click-through your div 'fog-container' which now sits 'on-top' of everything else when rendered, therefore, we can add these two properties to .fog-container: pointer-events: none; touch-action: none;

Hope this helps. Elegant, no? A push in the right direction? Hopefully!

to terminate the execution of signal handler in c

Asked 2021-May-13 at 16:16

i am currently working on project involving the interfacing of an ADC with Ras.-Pi using SPI communication. In the project I am controlling the initialisation of SPI using a timer, which then initiates a signal handler. In the signal handler the SPI transmission takes place and value is being stored in a variable, this variabler i am accesing in a thread and storing the recieved value in an array. The code runs but the program never comes out of the signal handler. I want the handler to jump to the thread to store the recieved value everytime it processes a value. Can someone point me to something reliable.

Answered 2021-May-13 at 16:16

If I understand correctly, you want a "status update" every x useconds of process execution (rather than of wall clock time, as SIGVTALRM implies ITIMER_VIRTUAL to me).

The safest, simplest way to do this will be to accept a pending signal, instead of delivering that signal to a signal handler.

Before spawning any threads, use pthread_sigmask to SIG_BLOCK at least SIGVTALRM. All new threads will inherit that signal mask. Then, spawn your status thread, detached, which sets an intervalic virtual clock timer and loops, waiting to accept VTALRM:
