UbuntuControlCenter (UCC) 0.6.1 released an update. This version is inspired by the layout of the manriva control center, a famous Linux release. It is not an official application, but is concise in design, allowing users to easily set up relevant systems. UCC allows you to easily set various system settings, such as low-quality and high-quality video cards. This version adds the system hardware information
Cisco Unified Communication, a company that proposes unified communication, is there any new action for Unified Communication in the era of cloud concept flooding? Now let's take a look at this consultation. So what is a new UCC solution made by BT, which is combined with Cisco's Unified Communication Technology?
BT and Cisco today announced the use of the BT Onevoice UCC service portfolio to launch a cloud

Ignore Peer SSL Certificate VerificationLibcurl performs peer SSL certificate verification by default. This is do by using a CA certificate store, the SSL library can use for make sure the peer's server certificate is VA Lid.If you communicate with HTTPS, FTPS or other tls-using servers using certificates that is signed by CAs present in the St Ore, you can being sure that the remote server really are the one it claims to be.If the remote server uses a self-signed certificate, if you don ' t ins

Curl error: Problem with the ssl ca cert (path access rights ?) Solution, curlcert
Curl error: Problem with the ssl ca cert (path access rights ?) .
Here is the CA problem: first, the CA that issues the server certificate is okay, so it should be a problem with the ca-bandle.crt that curl uses, this means that you have deleted some files in the/etc/pki/tls/certs/directory or set invalid permissions.

At the early stage of Ubuntu10.10 development, the Ubuntu Technical Committee considered not to support the suniscsi and IntelIA64 Cert architectures. Now the technical committee has voted to pass the decision: to abandon the support for both the iSCSI and IA64 architectures. In May June, the Ubuntu Technical Committee discussed this issue at the Ubuntu developer Summit and decided that if the feature freeze day of Ubuntu10.10 (August 12) if you are n

Recently, I learned C and wanted to do a big exercise. So I chose tetris. I am a computer science student. To tell the truth, the theory is okay, and my hands-on skills are poor. I asked my students to do it first, then I will explain to him how to

reading the questions, I thought of the topological sorting. I connected the site that did not appear in the train departure station and the terminal station to the site that appeared with a directed edge, you can find several layers of Topology Sorting. However, there is a problem here, that is, the reading of O (Mn ^ 2) and a large amount of computing, so the reading is slightly reduced by some loop range, the read complexity of the worst O (Mn ^ 2/4) is reached. In the topological sorting, t
Semantic checking of 4.2.4 function callsIn this section, let's discuss the semantic check of function calls, syntactically, the corresponding expression of a function call belongs to the suffix expression postfixexpression,ucc compiler exprchk.c function Checkfunctioncall () A semantic check of function calls was completed, as shown in 4.2.18. When reading this code, you need to understand the syntax tree after parsing for the function call, please r

always have finalizing, Unconsciously we have completed the UCC compiler analysis, all the way, the deepest experience is still "paper on the end of light, it is known that the matter to preach." According to this principle, the best way to understand the UCC compiler is to "read directly its source code, thi
5.1 Intermediate code Generation and Optimization _ IntroductionDuring the parsing and semantic review phases, we are always dealing with the 3 concepts of statement statement, expression expressions, and externally declared externaldeclaration. Through the declaration, we finally established the corresponding type structure, and in the symbol table holds the correlation identifier type information, in the intermediate code generation phase, we no longer need to deal with the external declaratio

C compiler profiling-managing the register for generating assembly code
In a computer, the CPU speed is much faster than the memory speed. The compiler should make full use of register resources to reduce unnecessary access to the memory, this increases the speed of the compilation code generated by the compiler. In the intermediate code generation stage, the UCC compiler uses the temporary variable t to store the values of common subexpressions such
