Useful and common task, should be well documented. Let´s try it! Debian 7.4 x64, PostgreSQL 9.3.2

Sometimes it would be very helpful to have a chance gather sample values. What if rownum limitation affects quality of records? What if the main table logic is residental in the middle of huge table? Welcome to data sampling world … Continue reading
Universal (HTTP/HTTPS, FTP, BitTorrent and Metalink) downloader, allowing mixed source protocols in CLI – impossible? Welcome to Aria2 world 🙂 Very short intro, skipping whole documentation and showing friendly software usage.
