Monads on the Cheap I: The Maybe MonadDon’t worry, this isn’t YAMT (Yet Another Monad Tutorial ). This is a practical post about a code smell that afflicts everyday code, and about an idiom that eliminates that smell. It just so happens that this idiom corresponds to one of the uses for monads in Haskell, but that’s just theory behind the practice, and I’ve saved the theory for the end.tagged: chainingjsjavascript09-02-2020

Biology and Control of Non-Biting Aquatic Midges | NC State Extension PublicationsNon-biting midge flies or chironomids commonly occur in both inland and coastal areas with natural and man-made bodies of water. These midges are commonly known as “blind mosquitoes” because they are mosquito-like in appearance but do not bite. Midges are also called “fuzzy bills” because of the male’s bushy antennae (Figure 1). These aquatic insects are tolerant of a wide range of environmental conditions. Chironomid midges can be found in swift moving streams, deep slow moving rivers, stagnant ditches, and in lakes and ponds that are rich in decomposing organic matter. The presence of certain chironomid midge species is often an indicator of water quality issues.tagged: midgespond09-01-2020
Troubleshooting | Vue CLIIf there're dependencies installed by npm link or yarn link, ESLint (and sometimes Babel as well) may not work properly for those symlinked dependencies. It is because webpack resolves symlinks to their real locations by default, thus breaks ESLint / Babel config lookup.tagged: linksvue09-01-2020

Fundamentals of Hierarchy in Interface Design (UI) - The Startup - Mediumvisual hierarchy is the order in which the user process information by importance.
