Answer : I was able to install pgadmin4 on ubuntu 20.04 (focal fossa) using the following article as a base: https://linuxhint.com/install-pgadmin4-ubuntu/ A few changes to the instructions are required: In part 2: sudo apt-get install build-essential libssl-dev libffi-dev libgmp3-dev sudo apt-get install python3-virtualenv libpq-dev python3-dev In part 5: The latest version for the moment is: https://ftp.postgresql.org/pub/pgadmin/pgadmin4/v4.20/pip/pgadmin4-4.20-py2.py3-none-any.whl (I used release, not a daily snapshot) In part 6: Use pip install pgadmin4-4.20-py2.py3-none-any.whl In part 7: Use 'python3.8' instead of 'python2.7' That's all. Worked for me. Update: Please note that it's possible install pgadmin4 (4.21) directly from the repositories now. The problem of the upstream debian repository was the python 3.8 support. They said that was fixed in this commit, but they are apparently missing this: https://github.com/postgre...

Answer : The two functions do vastly different things! The resize() method (and passing argument to constructor is equivalent to that) will insert or delete appropriate number of elements to the vector to make it given size (it has optional second argument to specify their value). It will affect the size() , iteration will go over all those elements, push_back will insert after them and you can directly access them using the operator[] . The reserve() method only allocates memory, but leaves it uninitialized. It only affects capacity() , but size() will be unchanged. There is no value for the objects, because nothing is added to the vector. If you then insert the elements, no reallocation will happen, because it was done in advance, but that's the only effect. So it depends on what you want. If you want an array of 1000 default items, use resize() . If you want an array to which you expect to insert 1000 items and want to avoid a couple of allocations, use reserve() . ...

Answer : There really isn't a single '2N2222' transistor, since each manufacturer just seems to use XYZ_2N2222 as a part number for a generic 'NPN silicon amplifier transistor'. Hence the 2N2222 pin-out is sadly not standardized. Most 2N2222s have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. However, some manufacturers have the pins going C-B-E for the TO-92 package. For example, the ON Semi P2N2222A variant: datasheet You can determine the pinout and NPN/PNP of an unknown BJT with the diode function of a digital multimeter in seconds. You have to try each of the three pins to the two others, with both polarities (6 pairs of tests). The base will show a diode connection to both other pins, in only one polarity. No other pin will show that. If the red test lead is on the base, then it is NPN, if the black is on the base, then it is PNP. Now you have identified the base pin and whether it...

Answer : Consider f − 1 ( y ) f^{-1}(y) f − 1 ( y ) , y ∈ Y y \in Y y ∈ Y . This set must be non-empty, regardless of y y y . What you're asking for is the number of ways to distribute the elements of X X X into these sets. The number of ways to distribute m elements into n non-empty sets is given by the Stirling numbers of the second kind, S ( m , n ) S(m,n) S ( m , n ) . However, each element of Y Y Y can be associated with any of these sets, so you pick up an extra factor of n ! n! n ! : the total number should be S ( m , n ) n ! S(m,n) n! S ( m , n ) n ! The Stirling numbers have interesting properties. They're worth checking out for their own sake. Here is a solution that does not involve the Stirling numbers of the second kind, S ( n , m ) S(n,m) S ( n , m ) . The number of surjective functions from a set X X X with m m m elements to a set Y Y Y with n n n elements is ∑ i = 0 n − 1 ( − 1 ) i ( n i ) ( n − i ) m \sum_{i=0}^{n-1} (-1)^i{n \choose i}(n-i)^m...

Answer : Important Your SMTP user name and password are not the same as your AWS access key ID and secret access key. Do not attempt to use your AWS credentials to authenticate yourself against the SMTP endpoint. For more information about credentials, see Using Credentials With Amazon SES. Here's the link: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html The issue is fixed in our case with the following : The AWS SMTP had special characters in its credentials . The credentials have to be url encoded and then provided in the configuration. If you're using Terraform, you can use the following .tf file so that you can get the proper data resource "aws_iam_user" "smtp_user" { name = "smtp_user" } resource "aws_iam_access_key" "smtp_user" { user = aws_iam_user.smtp_user.name } data "aws_iam_policy_document" "ses_sender" { statement { actions = ["ses...

Answer : If the last command fails pause won't work. You can fix it by putting "call" behind the command you are running (whatever command is before the pause) then the pause will work. So for example I had a phpunit batch file that looked like this: phpunit tests/sometests.php pause When phpunit failed it just exited without pausing. Changing it to this made it pause correctly: call phpunit tests/sometests.php pause Does the last command before pause execute successfully? Mind sharing your script - at least last few commands? Alternatively, since you seem to be using Windows7, try Timeout command and see if that is working. I was having issues even on echo... assuming it was caused by long batch file... Pause was executing but it was not pausing, it was almost like that it was pressing a key after Pause was executed. Tried suggested solutions above; none worked. So just for future reference, here is what I did: Basically just "pause > nul ...

Answer : if (!file_exists('http://example.com/images/thumbnail_1286954822.jpg')) { $filefound = '0'; } The function expects a string. file_exists() does not work properly with HTTP URLs. file_exists checks whether a file exist in the specified path or not. Syntax: file_exists ( string $filename ) Returns TRUE if the file or directory specified by filename exists; FALSE otherwise. $filename = BASE_DIR."images/a/test.jpg"; if (file_exists($filename)){ echo "File exist."; }else{ echo "File does not exist."; } Another alternative method you can use getimagesize(), it will return 0(zero) if file/directory is not available in the specified path. if (@getimagesize($filename)) {...}

Answer : For div tag there is already default property display:block given by browser. For anchor tag there is not display property given by browser. You need to add display property to it. That's why use display:block or display:inline- block . It will work. .btn { display:block; height: 300px; width: 300px; border-radius: 50%; border: 1px solid red; } <a class="btn" href="#"><i class="ion-ios-arrow-down"></i></a> .round-button { width:25%; } .round-button-circle { width: 100%; height:0; padding-bottom: 100%; border-radius: 50%; border:10px solid #cfdcec; overflow:hidden; background: #4679BD; box-shadow: 0 0 3px gray; } .round-button-circle:hover { background:#30588e; } .round-button a { display:block; float:left; width:100%; padding-top:50%; padding-bottom:50%; line-height:1em; margin-top:-0.5em; text-align:center; color:#e2eaf3; font-fami...
