The new iPad

Filed under: apple,Devices,ipad — Tags: , , , — liutyi @ 03:00

New iPad has great high resolution display. Some applications is already use it, but some still not updated and render in low resolution. New iPad has 1GB RAM and A5X processor. iPad 2 has A5 and 512MB RAM. CPU speed actually not changed. Only graphics is faster. Device heating up a little and weight noticeable more (+60 g). More time to charge needed.

Some test speed results could be found on

CPU benchmark:

135 iPhone
135 iPhone 3G
285 iPhone 3GS
390 iPhone 4

4.7 fps iPhone 4S

1.3 fps iPad
5.5 fps iPad 2

Except 5MP rear camera, only real improvement is retina display, GPU, memory and battery is simply adjusted to the new screen requirements.

For USA it also LTE/4G

Wi-Fi Router for Kyivstar/Beeline Internet at home

Filed under: HOWTO,router,wifi — Tags: , , , , , , , — liutyi @ 13:39

Хорошую скорость L2TP и PPTP тунелей для подключения к Домашнему интернету от Киевстар (бывший Билайн который в свою очередь бывший Голден Телеком) дают маршрутизаторы с прошивкой http://code.google.com/p/wl500g/. список поддерживаемых устройств http://code.google.com/p/wl500g/wiki/Devices

скорость L2TP туннеля для маршрутизаторов с прошивкой 1.9.2.7-rtn-r3702:
ASUS WL-500g Premium V2 (240МГц/32МБ/8МБ) составляет примерно 30 Мбит/с
ASUS RT-N16 (480МГц/128МБ/32МБ) составляет примерно 90 Мбит/с (60 Мбит/с с оригинальной прошивкой от АСУС)

Думаю сейчас (Январь 2011) ASUS RT-N16 самый быстрый из бытовых маршрутизаторов (с ценой порядка 100$) для доступа в Интернет с использованием тунеллей. Другие маршрутизаторы в зависимости от мощности их процессора и качества прошивки могут очень сильно ограничивать скорость работы с Интернет. Так довольно мощный Linksys WRT610N v1 (300МГц/64МБ/8МБ) дает порядка 6-8 Мбит/с с прошивкой dd-wrt.
