QUESTION
I'm ussing uwebsockets to create ws server.
main.cpp:
...ANSWER
Answered 2021-Apr-29 at 08:30It is because the compiler cannot convert 'brace-enclosed initializer list' to T&&. It can be solved by declaring the struct and converting it to Rvalue reference.
QUESTION
My project has linked uwebsockets. linked libs:
...ANSWER
Answered 2021-Apr-27 at 05:15Is there any linking sequence problem? I see that usockets
links behind libuv
, maybe we can try swap the sequence: to link usockets
first.
You are using static linkage, and usockets
depends on libuv
, so swap the sequence will fix the problem.

Would appreciate any help with this, as I have kind of run into difficulty with this module, after having discovered a bunch of homework I had overlooked. We are only 3 weeks in thankfully, but I really need to catch up.
Here is my code:

...ANSWER
Answered 2021-Feb-20 at 17:11The convention that EF core follows to figure out the primary key is this: either the field in the C# class is called Id
- or it's called (entity)Id
- in your case, that would have to be ShippersId
since the class is Shippers
- this is different from the ShipperId
that you currently have.
As such, EF Core will NOT automatically detect any primary key column. You need to either:
- rename your column to
ShippersId
so that EF Core can automatically detect it - decorate your column
ShipperId
with a[Key]
annotation to indicate this is the primary key column
Or as you mentioned as "solution": if you rename your class to Shipper
, then EF Core will now automatically detect ShipperId
as being the primary key.

I know that theres a latest version on github (websocket.js) by the same author, but I specifically need a version that works with discord.js. I tried installing a usable version, with
...ANSWER
Answered 2020-Dec-14 at 09:04I will refer you to these other posts for some detailed information on the subject.
This one involves the error you're referring to so it might be an answer to your problem. ELOOP Error
This one involves some good information on how to use npm in different ways that may be useful. npm outdated
I looked up the package and created a test folder to see if I could install the package you're talking about in there using npm i outdated uws@10.148.1
.
I then uninstalled it using npm uninstall outdated uws@10.148.1
Everything seemed to work fine besides all the deprication errors and warnings.
QUESTION
I'm trying to create an Android app that uses WebRTC data channels for data exchange. The data that I want to send is basic strings. Admittedly, this is my first time looking at WebRTC, and so I am a bit fuzzy on the details. My problem is that whenever I try to create a data channel, it is always null, and ICE candidate requests do not seem to be exchanged with the signalling server. I started from this example that creates a connection to exchange video between two devices and modified it to not exchange video but instead create a data channel.
I looked through a lot of other answers but the vast majority have to do with WebRTC in the browser, and data channel examples are rare to begin with. I also looked through the google chromium source code implementation of WebRTC in c++ to see if anything could be learned but had no luck.
My code is as follows
WebRtcActivity.kt

Answered 2020-Nov-17 at 23:53Answering my own question, not entirely but will post what worked for me. Ultimately I could not figure out what was wrong with the code above, I suspect somewhere I was not doing something right with the initialization or requests.
Some of the files are from above and have not been modified, but I'll post them anyways. Also, I had used this article as a starting point.

QUESTION
Ok, so I have a bot built in discord.js-commando
. I';ve been doing some tweaking to it, mainly trying to add some more functionality, such as logging commands and such to a channel by name as well as adding console.error logging.
Now my attempts to get channel logging are visible in the commands, however the bot keeps throwing a TypeError.... I have no idea what is causing this error or for that matter how to fix it.
Can someone please take a look at my code and help me figure out what is causing the TypeError?
This is the error I keep getting:
console.error
ANSWER
Answered 2020-Oct-01 at 01:38discord.js-commando@0.10.0
isn't compatible with discord.js@12
. It's package.json
specifies that Discord.js ^11.2.0
must be used.
The error is because Collection#filterArray
was removed in v12, and therefore this.commands.filterArray
is undefined
and not a function in the Commando code.
You have 2 options:
- Downgrade to Discord.js v11.
- Use the
master
branch ofdiscord.js-commando
, which is compatible with Discord.js v12. However, this branch may be unstable and/or have bugs.
To use this, change"discord.js-commando": "^0.10.0"
in yourpackage.json
to"discord.js-commando": "discordjs/Commando"
. See GitHub URLs in npm'spackage.json
documentation for more details on this.

QUESTION
I was trying to scrape a website called teamblind.com. Here is the start_url - referrals section.. It implements infinite scrolling on its pages and doing a simple crawl returns only 50 results. I would like to get all the posts within the referrals section.
This is my code -
...ANSWER
Answered 2020-Aug-11 at 08:41It should be technically possible to reverse engineer the site, but that would be far from trivial here, requiring to figure out how that payload is decoded by JavaScript. Tip: start by looking at payload
references in JavaScript files.
Otherwise, Splash is probably not a good fit, as each request would have to scroll down until reaching the desired page. As you reach later pages, the number or requests and the time required to get the target page will increment significantly.
So, if reverse engineering is out of the table, Selenium or a similar alternative would be the only way to go.

Can someone please look into the below error stack? I was trying to set up pinax.

Answered 2020-Jul-16 at 18:17the npm sass used by the project is node-sass@4.7.2 but the node i installed was 10 in order to use node-sass@4.7.2 node 8 must be installed not 10 . so uninstall node 10 and install node 8.
