Tutorial by Examples: critic



Some JavaScript engines (for example, the current version of Node.js and older versions of Chrome before Ignition+turbofan) don't run the optimizer on functions that contain a try/catch block. If you need to handle exceptions in performance-critical code, it can be faster in some cases to keep the ...
English text has the occasional diacritics. Loan words, like née, café, entrée Names, like Noël and Chloë Place names, like Montréal and Québec
double area; double h = 1.0 / n; #pragma omp parallel for shared(n, h, area) for (i = 1; i <= n; i++) { double x = h * (i - 0.5); #pragma omp critical { area += (4.0 / (1.0 + x*x)); } } double pi = h * area; In this example, each threads execute a subset of the iteratio...
If you'd like to start implementing best practices, for yourself or your team, then Perl::Critic is the best place to start. The module is based on the Perl Best Practices book by Damien Conway and does a fairly good job implementing the suggestions made therein. Note: I should mention (and Conwa...
h = 1.0 / n; #pragma omp parallel for private(x) shared(n, h, area) for (i = 1; i <= n; i++) { x = h * (i - 0.5); #pragma omp critical { area += (4.0 / (1.0 + x*x)); } } pi = h * area; In this example, each threads execute a subset of the iteration count and they accumul...
A letter with a diacritic may be represented with the letter, and a combining modifier letter. You normally think of é as one character, but it's really 2 code points: U+0065 — LATIN SMALL LETTER E U+0301 — COMBINING ACUTE ACCENT Similarly ç = c + ¸, and å = a + ˚ combined forms To compl...
Sometimes, one wants strings like "resume" and "résumé" to compare equal. That is, graphemes that share a basic glyph, but possibly differ because of additions to those basic glyphs. Such comparison can be accomplished by stripping diacritical marks. equals_ignore_mark(s, t) =...
Generally most of the exceptions are not that critical, but there are some really serious exceptions that you might not be capable to handle, such as the famous System.StackOverflowException. However, there are others that might get hidden by Catch ex As Exception, such as System.OutOfMemoryExceptio...
