Bancuri si Glume
De ceva vreme ma tot gandesc la un proiect de bloguri adica un conglomerat de bloguri sub un nume unic T2I (Time-2-Information).
avatare rele si/sau nervoase ;)

BIOS/loader
- LinuxBIOS is our BIOS for production units; Open Firmware is used as the bootloader.
Environmental specifications:
- Temperature: somewhere in between typical laptop requirements and Mil spec; exact values have not been settled
- Humidity: Similar attitude to temperature. When closed, the unit should seal well enough that children walking to and from school need not fear rainstorms or dust.

- Shock: 125g, 2ms, half-sine (operating) 200g, 2ms, half-sine (non-operating)
- Random vibration: 0.75g zero-to-peak, 10Hz to 500Hz, 0.25 oct/min sweep rate (operating); 1.5g zero-to-peak, 10Hz to 500Hz, 0.5 oct/min sweep rate (nonoperating)
- 2mm plastic walls (1.3mm is typical for most systems).
Regulatory requirements:
- The usual US and EU EMI/EMC requirements will be met.
- The laptop and all OLPC-supplied accessories will be fully UL and is RoHS compliant.
