kandi X-RAY | Wires Summary
Wires is a framework to build serverless applications in a compositional way. It is inspired by recent work in Category Theory, but, instead of mathematical beauty and perfection, we want to understand what is possible to build with current well-known technologies and without requiring too advanced skills from Wires end users. Several tools exists to describe serverless applications, e.g. Serverless Framework and Pulumi. The main difference between traditional tools and Wires is that, while the former ones say how to connect two services in a network, we want to compose full graphs in a uniform abstract way. We do not see Wires as an alternative to current solutions, but as a more abstract layer built on the top of them. The current implementation is based on Pulumi and would not have been possible without Pulumi closures.

QUESTION
I want to get the creation date of 20000 files and store it in an array.
Total time to complete is 35 minutes, quite a long time. (Image Processing Time)
Is there a way to create the array with faster processing time?
Is there any problem with the current logic to get an array of file creation dates like below?
① Array declaration: var arr = [];
② I used the code below to get the file creation date:
ANSWER
Answered 2021-Jun-10 at 03:45You're using fs.statSync which is a synchronous function, meaning that every time you call it, all code execution stops until that function finishes. Look into using fs.stat (the asynchronous version), mapping over your array of filepaths, and using Promise.all.
Using the fs.stat (the asynchronous version) function, you can start the calls of many files at a time so that it overall happens faster (because multiple files can be loaded at once without having to wait for super slow ones)
Here's an example of what I mean, that you can run in the browser:
QUESTION
Started to develop a wiresless 'cable' solution (with websockets) between two ESPs, a wireless serial 'cable' between computer and a serial device to mimick a direct wired connection. Was working great however just accidentally fried one of the ESPs (short a serial cable connection to higher voltage - sigh) when testing. Replaced one of the ESP32s with an ESP8266. Suspect this should work however it did not.
The problem is the ESP8266 (client) cannot find the network of the ESP32 (server). Why it doesn't work? My computer can see the server and can connect. Fried ESP32 the same, no problem.
Tried the WiFiScan demo on the ESP8266 and can detect all other WiFi SSIDs/MACs in neighborhood however cannot detect the ESP32 server it's SSID/MAC.
Why it doesn't work? What is the difference and how can I solve this?
ESP32 - code of the server
...ANSWER
Answered 2021-Jun-14 at 07:45WiFi channels 12-14 are not used in some countries (e.g. US). Perhaps the ESP32 AP picked one of those channels, and ESP8266 is configured by default with settings from a country which doesn't allow them. Set the AP channel to some reasonably safe value in range 1-11.
I can see that the default channel should be 1, but I'd suggest experimenting with it, perhaps setting it to 6:

QUESTION
Good afternoon, how to display post data by category in laravel livewire? here I want to try to display post by category data in the following way but it still doesn't work:
web.php
...ANSWER
Answered 2021-Jun-08 at 09:27Livewire components work slightly differently to blade views, they do not automatically inherit variables from their parents.
What you need to do is pass your category_id to the Livewire component.
QUESTION
Lately I have started implementing TLS for the sport as a fun project and I'm currently trying to self make and send locally a client hello TLS packet (a minimal one).
When observed via the loopback interface in Wireshark it appears as pure data instead of a tls layer with all of the various fields and after lots of trying I decided to ask here the following questions:
- What's the difference between my self made packet and a real TLS client hello one?
- How does Wireshark selectively makes one appear as a TLS layered instead of pure data, is there an identifier field in the packet that declares it as pure data or a TLS layered one?
- How can I make my packet to appear as a client hello TLS packet instead of pure data?
Here is my server and client that send basically my c code output (remember that they are not made for real TLS handling but just to show the packet in Wireshark):
server.py
...ANSWER
Answered 2021-Jun-01 at 21:45For starters, the TLS length field is wrong. Wireshark's TCP dissector indicates that the TCP payload length is 78 bytes; yet the TLS length is 165 (0x00a5), and thus can't be correct. Also, the handshake length is wrong too. Try changing this:

I installed livewire in my laravel project and created components, I add the components to the main file and they are displayed successfully. The problem comes when I attempt to use data binding and firing events which have completely failed to work. What could be the problem?
This is my main file.

Answered 2021-Jun-01 at 09:49first of all do not increment your counter in mount() , mount is called once so why do you need to do that ? and you are not calling any action on your component so i created a button to increment it .

QUESTION
I am using the ActiveMQ Artemis Broker and publishing to it through a client application.
Behavior observed:
- When my client is IPV4 a TLS handshake is established and data is published as expected, no problems.
- When my client is IPV6 , I see frequent re-connections being established between the client and the server(broker) and no data is being published.
Details:
- When using IPV6 the client does a 3 way handshake and attempts to send data. It also receives a Server Hello and sends application data.
- But the connection terminates and again reconnects. This loop keeps occurring.
- The client library, network infrastructure, and broker are all completely the same when using IPv4 and IPv6.
The client logs say:
...ANSWER
Answered 2021-May-26 at 08:36The issue was caused due to a LB setting which had a default connection time out of 30 secs , lesser than the connection timeout set by the client.
QUESTION
I want to get the contents of the zip file with func node with the following content, but I don't know why this node does it twice.
Where did I go wrong? Please tell me!
...ANSWER
Answered 2021-May-23 at 19:44You are calling both send(msg) and return msg
This will mean that you send 2 messages from the function node and since NodeJS/JavaScript is pass by reference they will both end up with the same content.
Best option is just to remove the return msg from the end of the function.
QUESTION
Is there a way to debug a handshake communication in Wireshark, I just need to check if the operation is correct or not, I have integrated TLS in MCU and want to send a GET request to my server, I can see the operation of handeshark in Wireshark, and the encrypted data sent to the server, but on the server side, I don't see any records added to the mysql database.
please see this image:
*for more info please see my second post is kinda related: stackoverflow
Log:
...ANSWER
Answered 2021-May-14 at 15:36The last line of the output shows "Application data". Application data are only transmitted if the TLS handshake was successful. Thus any problems you have are outside the TLS handshake.
