Headline Holiday season in the programming language world This month nothing much happened in the TIOBE index The programming language R continues to rise and is on schedule to become TIOBEs programming language of the year 2020 It is also interesting to follow the ongoing fight for position 10 in the TIOBE index between Go Swift and SQL Swift lost 2 positions this month from 10 to 12 SQL took over and is back in the top 10 this time Also worth noting is Groovys reentrance in the TIOBE index top 20 at the expense of Scratch and the fact that Hack entered the top 50 at position 44 Paul Jansen CEO TIOBE Software The TIOBE Programming Community index is an indicator of the popularity of programming languages The index is updated once a month The ratings are based on the number of skilled engineers worldwide courses and third party vendors Popular search engines such as Google Bing Yahoo Wikipedia Amazon YouTube and Baidu are used to calculate the ratings It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system The definition of the TIOBE index can be found here Aug

software Novos negócios e empresas A entrega do software é rápida Não tem fase de compilação Desvantagens Geralmente não são performáticas comparadas a linguagens compiladas O controle fino de recursos computacionais não é possível já que é feito pela VM Debbuging é complicado Type Safety é baixo devido ao uso de tipagem dinâmica Larry Wall criador do Perl Teve forte influência de outras ferramentas como AWK sed C e Bash Influenciou as principais linguagens modernas Ruby Python PHP e JS Trouxe a ideia de fazer um mesmo trabalho de várias formas diferentes Menção Honrosa Perl Criada em 1987 com um foco em processamento de texto Foi uma das percussoras da internet os scripts CGI que geravam páginas dinâmicas Quais são boas aplicações de linguagens de script Aplicações Planilhas

used to evaluate scripts using the Lua interpreter built into Redis starting from version 260 The first argument of EVAL is a Lua 51 script The script does not need to define a Lua function and should not It is just a Lua program that will run in the context of the Redis server The second argument of EVAL is the number of arguments that follows the script starting from the third argument that represent Redis key names The arguments can be accessed by Lua using the KEYS global variable in the form of a onebased array so KEYS 1 KEYS 2 All the additional arguments should not represent key names and can be accessed by Lua using the ARGV global variable very similarly to what happens with keys so ARGV1 ARGV 2 The following example should clarify what stated above eval return KEYS1KEYS2ARGV 1ARGV2 2 key1 1 key1 2 key2 3 first 4 second Note as you can see Lua arrays are returned as Redis multi bulk replies that is a Redis return type that your client library will likely convert into an Array type in your programming language Related commands EVAL EVALSHA SCRIPT DEBUG SCRIPT EXISTS SCRIPT FLUSH SCRIPT KILL SCRIPT LOAD httpsredisio httpsgithubcomopenrestylu
