kandi X-RAY | centrifuge Summary

centrifuge is a Go library typically used in Messaging, Pub Sub applications. centrifuge has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

This library has no v1 release, API still evolves. Use with strict versioning. Before v1 release patch version updates only have backwards compatible changes and fixes, minor version updates can have backwards-incompatible API changes. For all breaking changes we provide a detailed changelog. Master branch can have unreleased code. Only two last Go minor versions are officially supported by this library. Centrifuge library is a real-time core of Centrifugo server. It's also supposed to be a general purpose real-time messaging library for Go programming language. The library built on top of strict client-server protocol schema and exposes various real-time oriented primitives for a developer. Centrifuge solves several problems a developer may come across when building complex real-time applications – like scalability (millions of connections), proper persistent connection management and invalidation, fast reconnect with message recovery, WebSocket fallback option.

As of PHP 8.1, you have to fix the return type of the functions count() and getIterator() to match with interfaces.

public count(): int (see Countable)
public getIterator(): Traversable (see IteratorAggregate)

QUESTION

GAMS translated nonlinear objective function looks different than defined objective

Asked 2021-Apr-21 at 09:36

I am studying the batchdes.lst file for MINLP model batchdes in GAMS library. The objective function is

Defining objective function obj.. cost =g= sum(j, alpha(j)*(exp(n(j) + beta(j)*v(j)))); However, in the list of equations in the .lst file is presented as ---- obj =G= objective function definition

obj.. - (25141.1498186984)*v(mixer) - (64131.2769053431)*v(reactor) - (49066.7923833869)*v(centrifuge) - (41901.9163644973)*n(mixer) - (106885.461508905)*n(reactor) - (81777.9873056449)*n(centrifuge) + cost =G= 0 ; (LHS = -230565.365179047, INFES = 230565.365179047 ****)

What kind of operation has been applied here? How the exp() translated? Is this a feature of GAMS or the Solver selected?

I implemented the same model to Pyomo and solve with the same solver from GAMS, however the Obj does not look the same in the .lst file.

Thanks!

What you see here are the partial derivatives of each variable evaluated at their current level values. This comes from the GAMS documentation:

Nonlinear equations are treated differently. If the coefficient of a variable in the equation listing is enclosed in parentheses, then the corresponding constraint is nonlinear, and the value of the coefficient depends on the activity levels of one or more of the variables. The listing is not algebraic, but shows the partial derivative of each variable evaluated at their current level values.

QUESTION

jqGrid toobar not filtering when typing

Asked 2020-Oct-07 at 07:33

Using jqGrid js v5.5.0, the filter as you type functionality is not working for some fields.

Typing into the Title field causes the column to display only values that match what has been entered.

Typing a "2" into the Serial filter results in nothing being displayed.

The expected result is for the serial column to behave exactly as the title column and show partial matches.

All data is preloaded into the grid.

Here's the code and a Fiddle demonstrating the issue.

The problem you have is in definition in colModel and especially the index property.

This property can't have value with space. Moreover the index property when defined is used in searching. Your definition is:

React multiple import one module caching re-use

Asked 2020-Aug-16 at 14:43

I am using Centrifugo websocket server. I need to connect to Centrifugo and store connection instance for future usage from from multiple components.

Will it be the good way to create this kind of export from ./socket.js?
Will centrifuge.connect() and centrifuge.setToken('') be executed if I gonna import ./socket.js module muitiple times?

If you want to use a single instance only, it's better to import it in one place only. Best to import in the parent component and pass it as props to the children.

So your app.jsx would become:
