Certificate Transparency (CT) is an Internet security standard for monitoring and auditing the issuance of digital certificates. [1] When an internet user interacts with a website, a trusted third party is needed for assurance that the website is legitimate and that the website's encryption key is valid.
The ISRG provides free and open-source reference implementations for ACME: certbot is a Python-based implementation of server certificate management software using the ACME protocol, [6] [7] [8] and boulder is a certificate authority implementation, written in Go. [9] Since 2015 a large variety of client options have appeared for all operating ...
The 2014 guaranteed algorithm for the robust PCA problem (with the input matrix being = +) is an alternating minimization type algorithm. [12] The computational complexity is () where the input is the superposition of a low-rank (of rank ) and a sparse matrix of dimension and is the desired accuracy of the recovered solution, i.e., ‖ ^ ‖ where is the true low-rank component and ^ is the ...
Microsoft Windows in beta form on EC2, Microsoft SQL Server in beta form on EC2, plans for an AWS management console, and; plans for load balancing, autoscaling, and cloud monitoring services. [10] These features were subsequently added on May 18, 2009. [11] Amazon EC2 was developed mostly by a team in Cape Town, South Africa led by Chris Pinkham.
Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing.. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.
It focuses on analysis and construction of algorithms and programs, and the interaction of programs and architecture. Algorithms documented in TOMS are available as the Collected Algorithms of the ACM at calgo.acm.org. The purpose of the journal was laid out by its founding editor, John Rice, in the inaugural issue.

Communications of the ACM is the monthly journal of the Association for Computing Machinery (ACM). It was established in 1958, [2] with Saul Rosen as its first managing editor. It is sent to all ACM members. [3] [4] Articles are intended for readers with backgrounds in all areas of computer science and information systems. The focus is on the ...
Worldwide, the certificate authority business is fragmented, with national or regional providers dominating their home market. This is because many uses of digital certificates, such as for legally binding digital signatures, are linked to local law, regulations, and accreditation schemes for certificate authorities.
