  • Matching with IAC $IAC $MTCH
    Matching with IAC $IAC $MTCH IAC Interactive (IAC; disclosure: long) represents the opportunity to invest in a company trading for roughly the same price of its publicly traded equity stakes despite the presence of world class capital allocators with a proven history of realizing shareholder value at the opportune time, hundreds of millions in net cash on their balance sheet, and a grab bag of other (quite valuable) assets. Let me start with a bit of background: IAC is a conglomerate controlled by mogul Barry Diller. The company has a long and storied history which makes for interesting reading (at various points in time, they’ve owned big stakes in everything from a Japanese home shopping network to Ticketmaster and a variety of other big internet companies) but is a bit beyond the scope of this article; however, what is worth noting is that an investment in IAC since its inception in 1995 has destroyed a similar investment in the S&P 500: Anyway, today IAC has five main sources of value. I’ll go over them briefly below, but I’d encourage you to check out their FY16 letter for a bit more depth into their businesses: 1. Match.com (MTCH): IAC owns 80%+ of publicly traded Match.com, which owns Match, Tinder, and several other popular dating sites. 2. ANGI Homeservices (ANGI): IAC owns ~85% of ANGI Homeservices, which was formed by the merger of IAC’s HomeAdvisor with Angie’s List. 3. Video- IAC fully owns this segment, which includes Vimeo, CollegeHumor, Daily Burn, and a few others.

  • Remote Attestation on Light VM
    POLITECNICO DI TORINO Master's Degree in Computer Engineering Master Thesis Remote Attestation on light VM Supervisor prof. Antonio Lioy Candidate Fabio Vallone Accademic Year 2016-2017 To my parents, who helped me during this journey Summary In the last decade Cloud Computing has massively entered the IT world, changing the way services are offered to the final users. One important aspect of Cloud Computing is the needs to provide greater scalability and flexibility and this can be done by using a technique called Virtualization. This enables us to execute different virtualized ambient on a single piece of hardware. Each virtualized ambient can be seen as a node that offers some services to the final users by exchanging information with other nodes. For this reason the ability to trust each other is growing exponentially. This process is called Remote Attestation and it is from this consideration that the thesis work start. When we say that a node is trustworthy, we are saying that we are sure that all the file that are loaded into memory are the ones that are supposed to be loaded. In other word we need to be sure that the code, and in general the files loaded on that node, have not been tampered by anyone in order to produce a different behaviour of the node. It is important to note that we are not checking in anyway that the behaviour of the machine is logically correct, but we are simply checking that no one has modified it, so bug and logical error can still occurs in the code.

On Petition For A Writ Of Certiorari To The United States Court of Appeals For The Second Circuit BRIEF OF EBAY INC., NETCOALITION, THE COMPUTER & COMMUNICATIONS INDUSTRY ASSOCIATION, THE INTER- NET COMMERCE COALITION, TECHNET, NETCHOICE, AND TECHAMERICA AS AMICI CURIAE IN SUPPORT OF PETITIONER DAVID B.

ANGLIN BINGHAM MCCUTCHEN LLP 2020 K Street NW Washington, DC 20006-1806 (202) 373-6283 [email protected] Counsel for Amici Curiae QUESTION PRESENTED This case presents the issue that recently divided this Court, 4-4, in Costco Wholesale Corp. v. Omega, S.A., 131 S. Ct. 565 (2010). Under § 602(a)(1) of the Copyright Act, it is impermissible to import a work “without the authority of the owner” of the copyright. But the first-sale doctrine, codified at § 109(a), al- lows the owner of a copy “lawfully made under this title” to sell or otherwise dispose of the copy without the copyright owner’s permission. The question presented is how these provisions apply to a copy that was made and legally acquired abroad and then imported into the United States. Can such a foreign-made product never be resold within the United States without the copyright owner’s permission, as the Second Circuit held in this case? Can such a foreign-made product some- times be resold within the United States without permission, but only after the owner approves an earlier sale in this country, as the Ninth Circuit held in Costco? Or can such a product always be resold without permission within the United States, so long as the copyright owner authorized the first sale abroad, as the Third Circuit has indicated? i TABLE OF CONTENTS Page(s) QUESTION PRESENTED .......................................

  • Separating Protection and Management in Cloud Infrastructures
    SEPARATING PROTECTION AND MANAGEMENT IN CLOUD INFRASTRUCTURES A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Zhiming Shen December 2017 c 2017 Zhiming Shen ALL RIGHTS RESERVED SEPARATING PROTECTION AND MANAGEMENT IN CLOUD INFRASTRUCTURES Zhiming Shen, Ph.D. Cornell University 2017 Cloud computing infrastructures serving mutually untrusted users provide se- curity isolation to protect user computation and resources. Additionally, clouds should also support flexibility and efficiency, so that users can customize re- source management policies and optimize performance and resource utiliza- tion. However, flexibility and efficiency are typically limited due to security requirements. This dissertation investigates the question of how to offer flexi- bility and efficiency as well as strong security in cloud infrastructures. Specifically, this dissertation addresses two important platforms in cloud in- frastructures: the containers and the Infrastructure as a Service (IaaS) platforms. The containers platform supports efficient container provisioning and execut- ing, but does not provide sufficient security and flexibility. Different containers share an operating system kernel which has a large attack surface, and kernel customization is generally not allowed. The IaaS platform supports secure shar- ing of cloud resources among mutually untrusted users, but does not provide sufficient flexibility and efficiency. Many powerful management primitives en- abled by the underlying virtualization platform are hidden from users, such as live virtual machine migration and consolidation. The main contribution of this dissertation is the proposal of an approach in- spired by the exokernel architecture that can be generalized to any multi-tenant system to improve security, flexibility, and efficiency.
