Experimental patches under discussion for the GNU C Library (glibc) would make it easier to dynamically load optimized libraries (shared objects) on systems depending upon the CPU in use and its hardware capabilities. This glibc-hwcaps work stems from the desired work on being able to better leverage Linux performance optimizations on AMD Zen-based systems but the hardware capabilities patches themselves can help any CPU microarchitecture family in more easily shipping optimized support...

The mouse reporting functionality offered by the Linux VT console is rather basic and seemingly seldom used by text-based, mouse-aware programs. However, a series of patches was sent out this week for improving the implementation to provide for more xterm-like mouse reporting...

[8 minut čtení] Dnes sa oboznámime so spínačom Sonoff Basic založenom na čipe ESP8266, firmvérom Tasmota a pridám informácie o tom, čo si máte objednať, aby ste si nabudúce mohli do spínača nahrať nový firmvér. V prvej časti miniseriálu sa oboznámime s otvoreným firmvérom Tasmota, ktorý bol pôvodne vyvinutý práve pre spínače Sonoff, ale čoskoro sa rozšírila podpora aj na ďalšie zariadenia so známym čipom (tiež SoC, System on Chip) ESP8266. Je na ňom postavených mnoho zariadení využívaných v domácej automatizácii (spínačov, svetiel, snímačov apod.) od rôznych výrobcov a niekoľko typov vývojových dosák (napr. Wemos, NodeMCU, Adafruit HUZZAH, SparkFun ESP8266 Thing…).
