А знаете ли вы, что в Bash есть особая переменная "$_" ? Из описания можно узнать, что в переменную "$_" помещается последний аргумент последней команды. Что-то знакомое? Конечно, в Python есть примерно тоже самое. Мы знаем, что дата первого релиза Bash (8 июня 1989) несколько раньше чем первый релиз Python (20 февраля 1991). Если учесть, что по задумке автора Python это агрегация самых успешных практик отовсюду, можно ли сказать что именно эта фишка к нему пришла из Bash? Ни подтверждения ни опровержения я пока не нашел. Давайте просто считать это совпадением 😉 А как это может быть полезно в Bash? Приведу простой пример, который оценят те, кто часто работает в терминале. Допустим, нам надо создать директорию и зайти в неё. Что обычно делаем? :~$ mkdir foldername :~$ cd foldername :~/foldername$ Как это сделать в одну команду? :~$ mkdir foldername && cd foldername :~/foldername$ Уже лучше, но хочется короче, без повторов. Вот тут и пригодится наша переменная. Напомню, что в неё сохраняется последний аргумент предыдущей команды. :~$ mkdir foldername && cd $_ :~/foldername$ _________________ PS. Символы "&&"" разделяют команды и означают, что требуется выполнить вторую команду только если первая завершилась успешно. #linux#tricks

Disrupting Subscription Models A startup aimed at transforming content purchasing models could emerge as a billion-dollar company. Current subscription systems frustrate users who prefer one-time access without ongoing commitments. With over 70% of subscribers dropping off within 3-6 months, creators are hesitant to implement one-time payment options, as they often yield lower revenue. However, innovation in this area could change the game.

Insight on Pricing Strategy A Telegram bot for online store owners is launching with a subscription price of 320 rubles per month, which is lower than competitors to attract users. The creator struggled with pricing, consulting friends and family, leading to a divide in opinions. A seasoned relative advised that the price might be too low, suggesting a higher price to target a more serious audience. The discussion emphasizes that proper pricing should balance economic viability and marketing return, stating that high perceived value justifies higher pricing. Key takeaway: avoid relying on inexperienced opinions about business strategies. #Subscription#Ecommerce#PricingStrategy#MarketResearch#OnlineStore#BusinessAdvice#UserFeedback#ProductValue#Entrepreneur#Marketing#TelegramBot#ValuePricing#MarketCompetition#ConsumerInsights#Startup#BusinessModel

Market Trends Impact Developer Salaries Developers face salary stagnation as the job market grows competitive. With more candidates than job openings, mid-senior professionals find job switches yield minimal salary increases. Becoming a tech lead is rare and corporations limit hiring senior candidates. Stability may lie in entrepreneurship or pet projects instead. Consider exploring these options for long-term financial health. #JobMarket#DeveloperSalaries#Entrepreneurship#PetProject#IT#CareerGrowth#TechIndustry#EmploymentTrends#SalaryTrends#BusinessModel#Stability#Competition#JobSwitch#MidCareer#SeniorDevelopers#MarketAnalysis#ITCareers#FinancialPlanning#TechJobs#Startup#TechLeadership
