kandi X-RAY | nq Summary

nq is a C library. nq has no bugs, it has no vulnerabilities and it has medium support. However nq has a Non-SPDX License. You can download it from GitHub.

These small utilities allow creating very lightweight job queue systems which require no setup, maintenance, supervision, or any long-running processes. nq should run on any POSIX.1-2008 compliant system which also provides a working flock(2). Tested on Linux 2.6.37, Linux 4.1, OpenBSD 5.7, FreeBSD 10.1, NetBSD 7.0.2, Mac OS X 10.3 and SmartOS joyent_20160304T005100Z. The intended purpose is ad-hoc queuing of command lines (e.g. for building several targets of a Makefile, downloading multiple files one at a time, running benchmarks in several configurations, or simply as a glorified nohup), but as any good Unix tool, it can be abused for whatever you like. Job order is enforced by a timestamp nq gets immediately when started. Synchronization happens on file-system level. Timer resolution is milliseconds. No sub-second file system time stamps are required. Polling is not used. Exclusive execution is maintained strictly.

nginx reverse proxy by condition

Asked 2022-Apr-04 at 21:23

There are two web-apps:

an app for desktop browser;
an app for mobile browser;

Ahead of them there is nginx. I have a trouble to configure nginx's reverse proxy depending on a browser type (desktop/mobile).

There is an example of a config below:

ANSWER

Answered 2022-Mar-31 at 23:49

Well the "rewrite ... redirect" is executed by the client the "proxy_pass ..." from nginx servers.

I see 2 options:

Add resolver to the config
use 127.0.0.1 for localhost so that no resolving is necessary.

You can see the problem with resolving in this log line.

QUESTION

Navigating through different pages with onClick & radio buttons - React.js

Asked 2022-Mar-05 at 10:07

*Using react-router-dom and react.js

I have two different set of radio buttons. One set has 2 buttons while the other set has 3. I want to navigate to a new page whenever a user clicks on two buttons (one in each set). We have a total of six different outcomes, therefore 6 different pages to navigate to. It seems to work fine but with one problem: it only works when we click on a button for a second time. Example: Clicking on "Messages" & "Global" doesn't work initially and doesn't do anything but then if we click on a different button, then it navigates to the initial set of buttons we clicked.

Does anyone know how to fix this issue? Thank you.

Issue

The issue is that React state updates aren't immediately processed, they are enqueued and asynchronously processed later. The formData state update from handleChange is not yet available when test function is called as the same time.

Solution

It seems you want the act of navigation to be an effect of selecting from the radio buttons. Move the test function logic into an useEffect hook to issue the imperative navigation.

ANSWER

Answered 2021-Aug-27 at 13:21

I had this same problem and I got an answer here.

It's is because the line you read is always followed by a \n character. You need to remove it. Hence, just replace that last part of your code with this. .strip() will do for you. str(current_location).strip("\n")

Whenever you read a line from a text file, it adds a \n character to tell that new line started from there. You need to remove that while printing or it will mess up with your current statement

How can I write a tactic which works both in a goal and a hypothesis?

Asked 2022-Jan-08 at 13:43

I am trying to write a tactic which can work on goals and hypothesis similar to symmetry, but for inequalities as well. Now, there is some documentation on generalized rewriting, but this is very advanced and perhaps should be a different question. That said, here is my implementation which works (albeit awkwardly) for my use case:

You should not put classes into Razor pages (as a general recommendation, there might be cases where it is desired). However, it is possible by using the @functions keyword. The following answer elaborates on that topic.

ANSWER

Answered 2021-Oct-28 at 14:27

I suggest just using a for-loop for this as it's easier for me at least. To answer your question, why not just target until the period rather than the next A: | Q:? You'd probably have to use lookaheads otherwise.

(A: |Q: )[\s\S]*?\.

[\s\S] (Conventionally used to match every character though [\w\W] work as well)

*? is a lazy quantifier. It matches as few characters as it can. If we had just (A: |Q: )[\s\S]*?, then it'd only match the (A: |Q: ), but we have the ending \..

\. matches a literal period.

For the for-loop:

ANSWER

Answered 2021-Sep-07 at 01:17

There are three observable errors in the code presented here.

First, the DFF entity declaration is missing a separator (a space) between DFF and is.

Second, there are two drivers for signal q(0) In architecture arch of counter. The concurrent assignment to q(0) should be removed.

Third, the testbench doesn't provide a CLR = '1' condition for the clear in the DFF's. A 'U' inverted is 'U'.
