You can install Ubuntu Mate on your old laptop and keep at the same time Windows XP too, if you like XP. Or you can buy a tiny new laptop about 200-300 €/$ and change Windows 10 to Ubuntu. It works! I have made both about three years ago, and I haven't used Windows since then. My own laptop is cheap HP Stream 4 MB/32 GB. When I was studying Ubuntu, I noticed that simple beginner's guide books were not available. So, I did a guide book. I also created a website and named it www.ubuntutor.com. It currently includes Ubuntu 16.04 and 18.04 tutorials. And this guide is third one.

Total revenue grew by 21.4% YoY to a record US$2.99bn, beating market expectation. Subscription (recurring) revenue continued to drive the Adobe’s overall revenue growth. In terms of segment: 1) Digital Media remained the main contributor and its revenue reached US$2.08bn, up 21.6% YoY, driven by Document Cloud growth of 31.1% YoY; 2) Digital Experience reported revenue of US$858.5mn, up 24.5%, helped by Marketo acquisition last year. On the other hand, opex declined after lapping the Marketo/Magento acquisition. Operating margin expanded 400bps from 38.6% in 4QFY18 to 42.6% this quarter, which helped boost TTM FCF margin to 36.6% in Q4.

  • SEAL-Embedded: a Homomorphic Encryption Library for the Internet of Things
    IACR Transactions on Cryptographic Hardware and Embedded Systems ISSN 2569-2925, Vol. 2021, No. 3, pp. 756–779. DOI:10.46586/tches.v2021.i3.756-779 SEAL-Embedded: A Homomorphic Encryption Library for the Internet of Things Deepika Natarajan1 and Wei Dai2 1 University of Michigan, Ann Arbor, MI, [email protected] 2 Microsoft Research, Redmond, WA, [email protected] Abstract. The growth of the Internet of Things (IoT) has led to concerns over the lack of security and privacy guarantees afforded by IoT systems. Homomorphic encryption (HE) is a promising privacy-preserving solution to allow devices to securely share data with a cloud backend; however, its high memory consumption and computational overhead have limited its use on resource-constrained embedded devices. To address this problem, we present SEAL-Embedded, the first HE library targeted for em- bedded devices, featuring the CKKS approximate homomorphic encryption scheme. SEAL-Embedded employs several computational and algorithmic optimizations along with a detailed memory re-use scheme to achieve memory efficient, high performance CKKS encoding and encryption on embedded devices without any sacrifice of security. We additionally provide an “adapter” server module to convert data encrypted by SEAL-Embedded to be compatible with the Microsoft SEAL library for homomorphic encryption, enabling an end-to-end solution for building privacy-preserving applica- tions. For a polynomial ring degree of 4096, using RNS primes of 30 or fewer bits, our library can be configured to use between 64–137 KB of RAM and 1–264 KB of flash data, depending on developer-selected configurations and tradeoffs.
