QUESTION
This program reads the domain from a file to a string, truncates the string with "\n" as a key, and then executes the getostbyname() function for each domain to enter the resulting information into the file.
When I use gethostbyname, I want to create a function to enter fail if there is no response for a certain period of time. I tried to implement and process the timeout function, but the function did not work.
The logic that I thought of is calling gethostbyname() and entering fail in the file if there is no response for two seconds, then proceed to the next string and call gethostbyname().
The amount of files is about 150 million domains, so I took only a part of them and made them an example.
Please help me create the functions I want.

I am trying to add a menu bar to my website and it looks nearly the way I want it, with the hamburger to the left and the two contact info to the right. However, only the hamburger is sticky. Also, I would like to add a background color to the menu so that when the webpage is scrolled the sticky bits sit neatly inside the colored bar. How can I make these changes?
...ANSWER
Answered 2022-Mar-01 at 18:13You are so close to the solution. I really appreciate you for that.
I have deployed the code to the dummy URL: https://distracted-pasteur-66c13a.netlify.app/
You can use the following CSS to make your navbar sticky.

QUESTION
I've recently added Bull to my project to offload things like synchronizing documents to 3rd party services and everything's working well, except errors occurring while processing jobs don't end up in Sentry. They're only logged on the jobs themselves, but since we're running our application on multiple configurations, it means I have to constantly monitor all these instances for job processing errors.
I know I can add an error handler to a processor, but I have quite a few processors already, so I'd prefer another, more global, solution
Is there any way to make sure these errors are also sent to Sentry?
...ANSWER
Answered 2022-Jan-25 at 21:22I wasn't able to find a way to do this globally, but I was able to create a base processor class that implemented the OnQueueFailed Event Listener and reported failures to sentry. I have all my processors inherit from it and it seems to work well.
Base Class:
QUESTION
I have a PHP application that currently stores data in MySQL tables in non-conventional format(I assume this is because it is using a non-unicode mysql connection).
Example, this is one of the customer names as shown in PHP app UI:
DILORIO’S AUTO BODY SHOP
Notice there is a difference in apostrophe between it and the following.
DILORIO'S AUTO BODY SHOP
The latter one uses a standard latin apostrophe as oppose to unicode(i guess) style.
This name is stored in DB table like so:
DILORIO’S AUTO BODY SHOP
When it is being pulled from DB and displayed in UI it all looks correct, but the problem arised when I started to use MYSQL.Data C# connector to pull the same data.
At first I thought I should be able to just bull the value byte array and then convert it to latin1 (I assumed this is a default for PHP), however none of the existing encodings seemed to get me the result I wanted and this is what I get:
this is a DB collation for the field in mysql and how it looks:
Ideally I want to get rid of all corrupt data in DB and fix the PHP connection to unicode. But at this point it would be nice to just read whats already in there the same way as PHP is able to.
I also tried it with Encoding convert in all different combinations but no luck here either:
...ANSWER
Answered 2022-Jan-16 at 16:04The text is encoded with Windows-1252, not Latin1, which is why your attempts to decode it above failed. Once you convert the string to Windows-1252 bytes, then decode that using UTF-8, you should have the correct value:
QUESTION
I have a job server running Bull and express.
Server requirements
Receive a request containing an object and use that object as an input to a local programme (no other choice) which takes several minutes to a couple hours to run. The jobs MUST be run one after the other in the order they are received (no way round this).
TL;DR Server:
...ANSWER
Answered 2022-Jan-06 at 22:59Solved; it is amazing how writing out a question in full can inspire the brain and make you look at things again. Leaving this here for future Googlers.
See this from the Bull docs > https://github.com/OptimalBits/bull#separate-processes
I needed to invoke Bull's separate-processes. This allows me to run blocking code in a process separate from the node/express process which means future requests are not blocked, even though synchronous code is running.
QUESTION
I am implementing NestJS worker, queues, using Bull.
According to the documentation, both the worker and the server (will) run in a same "process", but I want to run the worker in a separate process, so as to not block the main event loop.
I think it's called "running a task in a separate binary" or something else.
Anyway, I tried googling it, went through the documentation of NestJS, but couldn't find something similar.
++ In other words:
I have a main project (my current), and I want to create the worker in a separate process (standalone application) and want to connect both my current main project and worker. And I can't really find it in the documentation.
In which module should I instantiate my Bull's instance? I am assuming I'll keep my producer in my main module and consumer in my worker module.
How can I do so?
Please note, by "separate process", I do not mean running a specific task in a separate process, as defined in Bull's documentation. I want to deploy the whole worker module in a separate process or whatever the term should be used.
++ [Extra, if possible]
Before running my server and worker, I also want to check whether my worker (bull instance) is successfully connected to my Redis server. I couldn't find anything on the Bull's documentation... do you think there is a good workaround for that?
...ANSWER
Answered 2021-Dec-05 at 01:41You can use that documentation to implement the entire worker. If you use Nest.js in standalone mode you can just have Processor(s) and Process(es).
This is documented here. “Separate binary” isn’t a question either. A binary is the product of compilation, Node.js isn’t compiled so you’ll need a separate application.
You don’t need a workaround for anything, this is literally the nature of Bull and optionally Nest.js.
Sometimes you’ll need to adapt examples in docs to fit your needs, this can take some time to learn.
TerminologyI think there's some confusion with terminology so in this post assume that:
- A
processis what yourapplicationruns inside (if you look in your OS process manager it should benode). - A
applicationis one Node.js project that runs in a separateprocess. - A
workeris anapplicationthat is only focused with processing Queue jobs. QueueandJobis terminology of Bull.ProcessorandProcessis terminology of Nest.js@nestjs/bull
Here is how you create an application with a worker running in separate processes. After following these instructions, you should see two processes running your process manager.
Create a new Nest.js application that we'll use for your worker:
