Would it discourage others from posting answers, if they saw that a question had an answer with a "works for me" indication applied immediately? (More so than just seeing an immediate, comprehensiv...
Before attempting this, make sure it makes sense in context. In a few particular situations, it would be better to take a different approach rather than using the normal tools for composing or f...
It's because of this rule: *{ background: rgb(3, 28, 87); } That applies the darker blue background to every element individually, and that isn't overridden when you change the background o...
Between-lines relations are not easy to look for with grep, which is a line filter. You could use a regex that spans lines, but I find this annoying because of all the flags you have to set. Grep ...
I have text (xml actually) files. Some files contain 'foo', some contain 'bar', some contain neither and some contain both. It's the both I'm interested in. How do I do an AND search on words in...
In git I branched feature-A from master. To reduce eventual merge conflicts later, I branched feature-B, which heavily overlaps and depends on A, from feature-A. A build of the feature-B branch s...
When doing something simple such as this int a=1; int b=2; int c=3; printf("%d\n", a + b * c); then I was told that operator precedence guarantees that the code is equivalent to a + (b * c)...
The sole purpose of the do { } while(0) is to write macros that accommodates to all manner of diverse coding styles. It is quite common not to use braces after if statements, so this is a common co...
The current two top questions at https://software.codidact.com/ ( https://software.codidact.com/q/279699 and https://software.codidact.com/q/278674) are marked as coming from luap42: However, wh...
The Problem I have a path optimization problem that in some ways reminds me of the Traveling Salesman Problem, but differs in some key respects. I have a group of items that need to be used by a m...
It is true that MISRA-C has a heavy focus on embedded system, though it has become somewhat more generic over time. The MISRA guidelines have been changed and improved several times over the years ...
I agree. Something that might be more useful is to allow the text boxes to be resizeable by the user. In most places, there's a small tab on the lower-right corner of a text box that allows the use...
When discussing best or safest C programming practices with various C gurus on the Internet, the "MISRA-C guidelines for the use of C language in critical systems" often pops up as a source. This ...
From time to time I will have large structural changes to make on my MySQL DB, things like adding columns, changing datatypes, adding indexes etc. These types of changes result in downtime and what...
Google Sheets isn't a company name, it's a product name. A tag called google-sheets is perfectly fine. Google doesn't market this product as "Sheets", they market it as "Google Sheets". What is not...
Any time an SQL SELECT query does not have any explicit ORDER BY clause, I personally find it useful to mentally read it as saying "I don't care about ordering of the output of this query". If you...
I'm trying to learn Linux, and I've got plenty of questions to ask on the subject, especially when it comes to differences between Linux's command line and Apple's. Would such questions be accepted...
I've got this sample regex: Pattern p = Pattern.compile("(?:([aeiou]+)[0-9]+|([123]+)[a-z]+)\\W+"); It basically has the following parts: one or more lowercase vowels ([aeiou]+), followed by one ...
Why would the second way be faster? Generally speaking, the first form will perform worse (as well as looking a lot worse) than the second. You are hitting an edge case where the opposite is true...
Context Over the years I had a hard time addressing questions about software architecture like these ones . Soon after posting them, they receive a couple of downvotes and close votes which set the...
I saw at least one compiler (Codewarrior for HC12) warn me if I use a function without using it's return value. Other compilers (clang/gcc) do not issue a warning though, even when using the std=90...
I'm trying to make a trait method callable on mutable slices of a type implementing that trait (see main). Rust doesn't like me for it. use core::convert::AsMut; trait A { type B; fn f(m: ...
After enabling two factor authentication (2FA) for my account I'm only notified It is successfully turned On. I think it should include some recovery codes as well (to be used in case I can't acce...
Facts In relational theory, each row in a relation is uniquely identified by a primary key. That's why some purists say that every table should have a primary key. Foreign keys usually reference a ...
SQL Server uses '1900-01-01' as a "zero-point" in DATEDIFF(dd, 0, some_date): select DATEDIFF(dd, 0, '1900-01-01') --> 0 select DATEDIFF(dd, 0, GETDATE()) --> 44066 days since the "zero-d...
