This series of summary should be accompanied by the project in a timely manner, but for the graphics card driver, itself can refer to very little information, only from the kernel code to do not try to figure it out. The purpose of the project is actually very simple and rude, why do you say so, because the work to be done involves implementing a 2D hardware accelerator on the embedded device, capable of supporting Mesa Open source 3D Graphics library, EGL,DLX and DRM modules.

Linus Torvalds announces the 3.12 stable version of the kernel, bringing a number of driver updates and improvements, such as Radeon Graphics, AMD APU, Qualcomm Owl/adreno,nvidia Optimus, various file systems and other driver updates.
Linus in the mailing list said: "I was hesitant to come to a RC8, but next week to travel, the internet is not good, or no delay." And said that after 3.19 will enter the 4.0 era, but that is a year later things.

1. Generate the root certificate of the key, 1024 means the RSA encryption digits, must be 2 of the n-th side, generally 1024 can be.
OpenSSL genrsa-out Ca.key 1024
2. Generate a CSR (certificate signing request) using the key of the root certificate that you just generate
The OpenSSL tool was planted on the OpenSSL, and after configuring the environment variable, execute the following command:
Create a root certificate and sign it with a self-signed signature
Create private key
OpenSSL genrsa-out Root/root-key.pem 1024
Create a certificate request
OpenSSL req-new-out Root/root-req.csr-key Root/root-key.pem

HTTPS is often used in our development of communication encryption technology, can effectively protect our network access security, this article mainly explains the configuration of one-way and two-way https. About the implementation of the principle of HTTPS here I will not repeat, attached to the Nanyi teacher about the https introduction of several blogs, interested in children's shoes can take a look at: The diagram of the SSL/TLS protocol digital signature is what.

NVIDIA's public version. As NVIDIA's current next-high-end model, gtx770 is not a strikethrough version of gtx780 in terms of hardware configuration, but is equipped with the gk104 display Core Used by GTX 680, in addition to the high frequency, the memory size is similar to that of gtx680. This gtx770 looks like an "Upgrade" of gtx680 ".
