The Linux Heart Archive

This is the earlier Linux Heart: technical discoveries, short news items, personal opinions and the occasional detour. They belong to the story of this blog, even where the product, service or debate has long since moved on.

The original dates and addresses are preserved. Technical posts have English translations; some personal entries remain in their original language. A revisited guide keeps the original account alongside a separately dated follow-up. The archive is available for reading without advertising.

For practical walkthroughs, start with the selected engineering guides. For current product and marketing stories, return to the journal.

  7. Hosting.ua: клиенты-идиоты или естественный отбор

    На форуме недоразвитых Willy-диотов очередной кипиш, у сеонизаторов накрылся хостинг. Скажу точнее - он физически сгорел... В славном городе Одессе какие-то лохи купили домен hosting.ua…

  15. Фрилансеры – почему так мало нормальных?
