sane | sane aims to be fast , small , and reliable filesystem watcher | Runtime Evironment library

In Python, the following code lets me replace most sanely-written text case-consistently. It has bugs if, say, from_substring is "the" and my_string contains "theater," but this is just to illustrate what I want to do.

We support an application that has some bad design. This application stores data in a Cassandra cluster in a TEXT column and sometimes writes quite large Strings in this column and we get a WriteFailureException.

Cassandra has a limit on the write size (16mb by default: https://docs.datastax.com/en/dse/6.7/dse-admin/datastax_enterprise/config/configCassandra_yaml.html#configCassandra_yaml__max_mutation_size_in_kb) which is great. We would like to notify the user that they are trying to write a large chunk of data in case such limit is reached. As I understand there is no way to distinguish whether this exception occurred because of this limit or due to any other errors inside the Cassandra cluster.

It would be even better to check if the size of the date exceeds the limit before trying to write it in Cassandra. Java String is UTF-16, Cassandra's TEXT is UTF-8, so my naive approach is to convert a String to UTF-8 and check it's size like that: s.getBytes(StandardCharsets.UTF_8).lenght()

However this seems quite expensive to convert a String to UTF-8 just to throw it away. Is there a sane way to do it? How do people check if their data fits in Cassandra before writing it?

I'm new to the javascript world, I have no experience with typescript, node.js etc I'm more accustomed to OOP languages like Java.

I'm developing a web application with PHP (locally hosted on an Apache server) that generates HTML server-side with a template engine , then I use javascript to do client-side operations like dynamically adding buttons on clicks, ajax requests, parse dynamically generated forms to build a json request body and so on.

I quickly realized that developing complex components with javascript is quite messy, a single file with all the classes, all the functions, no type checking, and now a single component is already 500 lines of codes, with the potential to grow more (also, I have to make more of these on various pages).

Debugging a massive and complex single file is already becoming a daunting task. I could split the file into many pieces, but then I have to manually import them with multiple

I am iterating over a bunch of null-terminated C strings of type [c_char; 256] and have to compare them against a handful of hardcoded values and ended up with the following monstrosity:

I was trying to follow solution 1 in @rmtmckenzie's answer to a similar question (Persisting AppBar Drawer across all Pages Flutter but when I try the following code, I get the error The argument type 'SaneAppBar' can't be assigned to the parameter type 'PreferredSizeWidget?'. Since I can assign a non-nullable member to a nullable member (e.g. String? = String), I don't get what I'm doing wrong. Perhaps this is something you can do with a drawer parameter but not with an appBar parameter? If so, I'd appreciate any pointers to how I should have been able to determine this up front. I'm also wondering if the sample code needs to be modified to work in a null-safety environment?

I have a big numpy 2d array F which has complex numbers (np.complex64). It has a lot of very small numbers. For the sake of my calculation, I only need precision of ~1e-6 - 1e-9. Since this matrix is very large, I am trying to use a sparse matrix representation. So I try to do this:

I found myself needing to do camel case to sentence case string conversion with sane acronym support, a google search for ideas led me to the following SO post:

Convert camelCaseText to Sentence Case Text

Which is actually asking about title case not sentence case so I came up with the following solution which maybe others will find helpful or can offer improvements to, it is using ES6 which is acceptable for me and can easily be polyfilled if there's some horrible IE requirement.

I wrote a function that will return a single sql record as a dictionary. Is it possible to return an array of dictionaries so I can return multiple records in this way?

In my chat app I have users and chats. The tables for each of these is connected by a join table:
