Javascript filtering a nested array to exclude objects that don't include one of several elements

Asked 2021-Jun-05 at 10:58

I have a fairly simple nested array of objects. Each object is composed of 5 (string) values, e.g. ["0,0", "0,0", "0,0", "0,0", "0,1"]. There are no variables attached, hence using arrays inside an array.

Each object represents a puzzle solve permutation being tested by other parts my code. The main data set is composed of 150k permutations.

Test if string contains another string as single Word

Asked 2021-Jun-03 at 11:17

How can I case insensitive test if a string contains another string as a single word? The needle is not allowed to have any other letters [a-z] around it.

Here are a few examples:

...

ANSWER

Answered 2021-Jun-03 at 10:37

I've got this regex /(?<=[^a-z]|^)text(?=[^a-z]|$)/i.

It means: check for text without [a-z] or text start before, and without [a-z] or text end after. The /i is for incasesensible.

Note that it matches when there is a number after 'text', if you want to exclude numbers from matching the discartion group becomes [^a-z^\d] (\d for digits).

EDIT: With a bit more of research, I found that there is a better way to do that. It's called word boundaries, and consists in just add \b before and after your word: /\btext\b/i.

How is the complexity of algorithm to find LPS(Longest prefix which is also a suffix) array is O(n)?

Asked 2021-Jun-01 at 19:33

Following is my implementation of the algorithm to find the LPS array which is part of the KMP algorithm.

...

ANSWER

Answered 2021-Jun-01 at 19:33

What is j? This is length of current prefix.

At every step we make suffix longer by one, and we may get coinciding prefix longer by one. But prefix length might become smaller, and sometimes zero. But if we make prefix of zero length, and will expand it one char-by-one, we have to perform a lot of operations. Instead this algorithm uses smart optimization - prefix length is diminished by one to reuse already calculated information.

The most important moment - overall number of prefix reductions cannot exceed string length - that is why complexity is linear.

QUESTION

Jhipster Spring Boot 2 instances of a microservice on different databases

Asked 2021-May-25 at 19:18

In my project I'm using Jhipster Spring Boot and I would like to start 2 instances of one microservise at the same time, but on different instances of a database (MongoDB).

In this microservice I have classes, services, rests that are used for collections A, B C,.. for which now I would like to have also history collections A_history, B_history, C_history (that are structured exactly the same like A, B, C) stored in separated instance of a database. It makes no sense to me to create "really separated" microservice since I would have to copy all logic from the first one and end up with doubled code that is very hard to maintain. So, the idea is to have 2 instances of the same microservice, one for A, B, C collections stored in "MicroserviceDB" and second for A_history, B_history, C_history collections stored in "HistoryDB".

I've tried with creating 2 profiles, but when I start from a command line History microservice, it is started ok, but if I also try to start "original" microservice at the same time, it is started but immediately history service becomes "original" microservice. Like they cannot work at the same time.

Is this concept even possible in microservice architecture? Does anyone have an idea how to make this to work, or have some other solution for my problem?

Thanks.

ANSWER

Answered 2021-May-20 at 09:18

In general, this concept should be easily achievable with microservices and a suiting configuration. And yes, you should be able to use profiles to define different database connections so that you can have multiple instances running.

I assume you are overwriting temporary build artifacts, that's why it is not working somehow. But that is hard to diagnose from distance. You might consider using Docker containers with a suiting configuration to increase isolation in this regard.

QUESTION

Search in a string literal with a table field with peewee ORM

Asked 2021-May-21 at 16:40

I am trying to find all the records for which a certain field matches the beginning of a string literal provided as a fixed parameter. The needle is a field from a table.

Example: Given a parameter 'John Doe', I would like to get all the records of the table user, for which the first_name field is a sub-string of the beginning of that 'John Doe' string (e.g. matching records would be those for which the first_name is 'John', or 'Jo', or 'Joh', etc.

It seems I can achieve this with the following SQL:

SELECT * FROM user WHERE 'John Doe' LIKE first_name || '%'

Now how to translate that to peewee? It's strange that I am able to actually obtain the correct SQL for this but for some reason peewee is returning an empty result while the same query is working when I enter it directly via SQLite command line.

User.select().where(SQL("'John Doe'").startswith(User.first_name))

When I check the sql() of this, it shows:

('SELECT "t1"."id", "t1"."first_name" FROM "user" AS "t1" WHERE ("John Doe" LIKE ("t1"."first_name" || ?))', ['%'])

But the result is empty. Same SQL in the command line returns the right record... What am I doing wrong?
