To launch an AceBase webserver using default settings. NOTE: The above code will create an admin user with a generated password, which will be displayed once in the console output. Only randomly salted SHA512 hashes of user passwords are stored in the auth database, so it'll become fairly hard to sign into the admin account if you don't copy/paste the password somewhere. If you don't want to use a generated password, see Enable authentication below for info about how to supply a default password.

QUESTION
I have an array of 5 numbers, I'd like to match as long as there are three of the same number and two of the same different number in the array, placement does not matter. Number sequences can be any random string of 5 numbers between 1 - 5.
Examples of matches would be:
33322
24422
52225
44111
54545
*basically any grouping of 2 and 3 of the same numbers needs to match.
Best I've come up with so far:
^([0-9])\1{2}|([0-9])\1{1}$
I am not so good with regex, any help would be greatly appreciated.

...ANSWER
Answered 2022-Jan-06 at 04:57A simple solution would be to convert all characters to lowercase, replace any character that isn't a-z, 0-9, or a space with a space character, and then replace multiple space characters with a single space character.

QUESTION
Java 11 added some new methods to the Pattern class (a compiled version of a regular expression), including:
I am trying to understand the difference between the two and when I would want to use one over the other?
...ANSWER
Answered 2021-Nov-16 at 14:57Pattern.asPredicatewill return true if any part of the input string matches the Regular expression. You should use this method if you're testing some larger body of text for a certain pattern. For example, to test whether a comment from a user contains a hyperlink.Pattern.asMatchPredicatewill return true if the entire input string matches the Regular expression. You should use this method if you're testing the entire input for a certain pattern. For example, to validate the phone number of a user in their profile.
Pattern.asPredicate internally uses Matcher.find(), while Pattern.asMatchPrediate internally uses Matcher.matches(). So the difference between the two boils down to the difference between these two methods from the Matcher class.
Below are some examples to showcase the difference. You can copy & paste below code in an online Java sandbox like https://www.compilejava.net/ to play around with it yourself.
QUESTION
I am trying to replace a single occurrence of a character '1' in a String with a different character.
This same character can occur multiple times in the String which I am not interested in.
For example, in the below string I want to replace the single occurrence of 1 with 2.

I have a Json file having multiple comments and I want to replace a value in it.
I tried the below and it gives me a json file without comments. But I don't understand how to change the value and save it back with comments. Is this even possible because we are replacing all the comments with empty lines?

QUESTION
The header question may not be easy to understand. Hope you can understand my detailed info below.
I have sentence data below, that has some tags, represented by [tn]tag[/tn]:
ANSWER
Answered 2021-Oct-04 at 08:47Here is a solution that assumes that there are no nested tags, that all tags open and close in the part. Also, this assumes that all characters from the sentence are in parts. For this last assumption, I had to add the . after it has to be in the second expected part. I also had to remove newline characters from the sentence but I think it was because of the copy/paste.
This solution will loop through all characters and store two parallel buffers : one with the tags, one without. We will use the second one to compare with the parts, and use the first one to generate the output.

Install acebase-server
If you enabled authentication, you can also define access rules for your data. Using rules, you can allow or deny specific (or anonymous) users read and/or write access to your data. These rules are identical to those used by Firebase (Note: ".read" and ".write" only, ".validate" might be implemented in the future, ".schema" implemented as alternative) and are saved in a file called rules.json in your database directory. The default rules written to the file are determined by the defaultAccessRule authentication setting at the first server launch with authentication enabled.
"auth": Only allow authenticated users read/write access to the database
"allow": Allow anyone (including anonymous users) read/write access to the database
"deny": Deny anyone (except admin user) read/write access to the database
No read or write access to the root node or any child for anyone. (No rule has been set for those nodes, access will be denied)
Read access to all reviews for specific shops ('shop_reviews/shop1', 'shop_reviews/shop2') for anyone, including unauthenticated clients (".read" rule is set to true)
Write access to an authenticated user's own review for any shop. (".write" rule is set to "auth.uid === $uid")
v0.9.7: user accounts and server logs are now stored in the target database, instead of in a seperate auth database. If you upgraded from version 0.9.6 or lower and want to keep using the existing auth database, start the server with seperateDb: true in the options.
