Recently, I was working on flutter and cited Aurora push manufacturers. I encountered {get manifestoutputdirectory error when packaging
Version: Android studio 4.1; Gradle 6.7
Solution:
Modify
classpath 'com.android.tools.build:gradle:4.1.0'to
classpath 'com.android.tools.build:gradle:4.0.2'In the process of Jenkins building Maven project, the configuration source code management reports an error:
remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.
refs/heads/*: refs/remotes/origin/* "returned status code 128: stdout: stderr: fatal: unable to access

Solution: add a global certificate and use it in project configuration -> source management ->Use this voucher
Build again:
install Jenkins command under docker (Mount: Java and Maven) pay attention to the host directory
docker run -d -p 8089:8080 -p 8090:50000 -v /usr/local/jenkins:/var/jenkins_home -v /usr/local/jdk:/usr/local/java -v /usr/local/dev/apache-maven-3.6.3:/usr/local/maven -v /etc/localtime:/etc/localtime --name myjenkins jenkins/jenkins:lts

Solution to Channel-Offset Error when the same circuit module of ad20 PCB is multiplexed in room format
1. Problem phenomenon
We often encounter the following problems when using room format to quickly layout circuits of the same module,
2. Solution
There are many processes of copying PCB layout of the same module circuit on the Internet, which will not be repeated here. The steps are similar, only the root cause of the problem
1: check whether the following three status settings are correct or not? 
2: Channel Offset I recommend using the box, that is, select the first table and then pull down, paste the same; if you are in accordance with the EXCEL table as click Channel-Offset, and then right-click to copy, the results may lead to no copy success;.
3: before pasting, pay attention to keep the device arrangement order of the original circuit and the target circuit consistent
my main problem is the second point. I thought the copy was successful, but I didn’t copy it, so I didn’t paste it. Finally, I kept reporting errors, which annoyed me!
After this @truffle/hdwallet-provider will be successfully installed – then reference in required file as follows:
var HDWalletProvider = require("@truffle/hdwallet-provider");Reference: nodejs – Error: Cannot find module ‘truffle-hdwallet-provider’ – Ethereum Stack Exchange

The solution is as follows:
The reason for the error should be that there are no synchronized observations, or the synchronized observations are too short.
Under the rinex folder, verify the gnss data file that confirms the synchronized observations.
Problem description
Edit formula:
$\begin{align}
& \sum\limits_{i=1}^{n}{k=\frac{1}{2}}n(n+1) \\
& \text{ }=\Theta ({{n}^{2}}) \\
\end{align}$
Markdown Error: ParseError: KaTeX parse error: {align} can be used only in display mode
Error: KaTeX parse error: No such environment: align at position 7: \begin{̲a̲l̲i̲g̲n̲}̲ & \sum\limit…
Solution:
Modify {align} to {aligned}, KaTeX is not support align, you need to modify to aligned.
Layout
Next, modify the formula layout so that the formula surrounded by $$ by KaTeX is centered.
\limit can make n and i=1 located directly above and below the accumulation symbol.
$$
\begin{aligned}
\sum_{i=1}^{n} k &=\frac{1}{2} n(n+1) \\
&=\Theta \left(n^{2}\right)
\end{aligned}

After installing RAC, I encountered [INS-06006] Passwordless SSH connectivity not set up between the following node(s) when installing Oracle, rac1 and rac2 mutual trust. When the Setup was executed successfully, the passwordless login was already available on the OS, but Test did not work, so the following steps could not be performed.
Solution: I found that the problem lies in the virtual NIC virbr0 that comes with the virtual machine, remove the virtual NIC.
1. ifconfig virbr0 down
2. brctl delbr virbr0
3. systemctl disable libvirtd
4. Restart the virtual machine
5.Remove the original /home/oracle/.ssh file, and reset,test it.
In a word:
vue2 uses vetur, and vue3 uses volar
Error indication:
vue2 items in the template must be wrapped by using a root element;
Solution:
in vue3 project, Vue related plug-ins use Volar
In the vue2 project, use the plug-in Vetur
No more errors

cv2.error: OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\dnn\src\dnn.cpp:562: error: (-2:Unspecified error) Can't create layer "feature_fusion/truediv" of type "RealDiv" in function 'cv::dnn::dnn4_v20191202::LayerData::getLayerInstance'
Solution:
It has three places to modified in model.py
1. Comment out this line: #images = mean_image_subtraction(images)
2. c1_1 = slim.conv2d(tf.concat([g[i-1], f[i]], axis=3), num_outputs[i], 1)
3. pi2 = 0.5 * np.pi
angle_map = (slim.conv2d(g[3], 1, 1, activation_fn=tf.nn.sigmoid, normalizer_fn=None) - 0.5) * pi2
F_geometry = tf.concat([geo_map, angle_map], axis=3)
