Hướng dẫn tạo USB-GPT cài win 7-8-8.1 boot chuẩn UEFI
Có nhiều cách để tạo 1 USB cài win,
tool thì cũng có nhiều, nhưng mình vẫn thích nhất là "tay không bắt
giặc" vì cách này nhanh nhất, chuẩn nhất, và cũng chủ động nhất, có thể
các bạn chưa quen thì thấy là chậm hay loằng ngoằng, nhưng khi đã quen rồi thì
tốc độ là số 1, vù cái đã xong.
Bắt đầu nào: chuẩn bị 1 em USB từ 4GB trở lên, file ISO win7/8 64-bit

Các PAN Nec/Tokin
Các bệnh liên quan quan đến tụ điện Nec/Tokin thì đã quá "thường" rồi. Rất rất nhiều nơi đã đề cập, chỉ cách khắc phục. Nên lqv77 sẽ không nói lại, chỉ muốn note lại chút xíu thôi:
1. Pan này là do thủ phạm chính là tụ Nec/Tokin gây nên.
Tình trạng: Dùng Pin thì bình thường. <-- 4="" adpater="" b="" c="" ch="" d="" h="" i="" kh="" khi="" m="" n="" ng="" nh...="" nh="" nha.="" ok="" p="" ph="" pin="" r="" ra="" s="" sinh="" t="" th="" treo="" tri="" u.="" u="" v="" x="" y="">

Configuring Sendmail to relay through Gmail SMTP
Sending email directly from the MTA (mail transfer agent) on one’s server is now considered to be faux pas. Unless you’ve got that machine configured within DNS (MX record, reverse lookup, etc), it’d likely fail most basic spam checks at the destination mail server. The complexity of the configuration increases if you’ve got the need to masquerade emails from multiple domains. Instead, the ideal approach is to relay through a central SMTP gateway for all of the outbound emails generated from your server(s).
I’ve been on Google mail hosting for a long time now and needed to configure my server to relay mail through it. Here’s a nice article that walks you through exactly what needs to be done to configure your sendmail MTA to relay through Gmail’s SMTP servers. Another similar post here.
