  • Thriving in a Crowded and Changing World: C++ 2006–2020
    Thriving in a Crowded and Changing World: C++ 2006–2020 BJARNE STROUSTRUP, Morgan Stanley and Columbia University, USA Shepherd: Yannis Smaragdakis, University of Athens, Greece By 2006, C++ had been in widespread industrial use for 20 years. It contained parts that had survived unchanged since introduced into C in the early 1970s as well as features that were novel in the early 2000s. From 2006 to 2020, the C++ developer community grew from about 3 million to about 4.5 million. It was a period where new programming models emerged, hardware architectures evolved, new application domains gained massive importance, and quite a few well-financed and professionally marketed languages fought for dominance. How did C++ ś an older language without serious commercial backing ś manage to thrive in the face of all that? This paper focuses on the major changes to the ISO C++ standard for the 2011, 2014, 2017, and 2020 revisions. The standard library is about 3/4 of the C++20 standard, but this paper’s primary focus is on language features and the programming techniques they support. The paper contains long lists of features documenting the growth of C++. Significant technical points are discussed and illustrated with short code fragments. In addition, it presents some failed proposals and the discussions that led to their failure. It offers a perspective on the bewildering flow of facts and features across the years. The emphasis is on the ideas, people, and processes that shaped the language. Themes include efforts to preserve the essence of C++ through evolutionary changes, to simplify itsuse,to improve support for generic programming, to better support compile-time programming, to extend support for concurrency and parallel programming, and to maintain stable support for decades’ old code.

It seems like everyone these days is downloading, watching, and sharing videos from video-sharing sites like YouTube, Google Video, MetaCafe, DailyMotion, Veoh, Break, and a ton of other similar sites. Whether you want to watch the video on your iPod while working out, insert it into a PowerPoint presentation to add some spice, or simply download a video before it’s removed, it’s quite essential to know how to download, convert, and play these videos. There are basically two ways to download videos off the Internet and that’s how I’ll split up this post: either via a web app or via a desktop application. Personally, I like the web applications better simply because you don’t have to clutter up and slow down your computer with all kinds of software! UPDATE: MakeUseOf put together an excellent list of the best websites for watching movies, TV shows, documentaries and standups online.

  • Basic Performance Measurements of the Intel Optane DC Persistent Memory Module
    Basic Performance Measurements of the Intel Optane DC Persistent Memory Module Or: It’s Finally Here! How Fast is it? Joseph Izraelevitz Jian Yang Lu Zhang Juno Kim Xiao Liu Amirsaman Memaripour Yun Joon Soh Zixuan Wang Yi Xu Subramanya R. Dulloor Jishen Zhao Steven Swanson* Computer Science & Engineering University of California, San Diego arXiv:1903.05714v3 [cs.DC] 9 Aug 2019 *Correspondence should be directed to [email protected]. Copyright © 2019 the authors. 1 2019-08-09 7041bc9 Abstract After nearly a decade of anticipation, scalable nonvolatile memory DIMMs are finally commercially available with the release of the Intel® Optane™ DC Persistent Memory Module (or just “Optane DC PMM”). This new nonvolatile DIMM supports byte-granularity accesses with access times on the order of DRAM, while also providing data storage that survives power outages. This work comprises the first in-depth, scholarly, performance review of Intel’s Optane DC PMM, exploring its capabilities as a main memory device, and as persistent, byte-addressable memory exposed to user-space applications. For the past several months, our group has had access to machines with Optane DC memory and has investigated the Optane DC PMM’s performance characteristics. This report details the chip’s performance under a number of modes and scenarios, and across a wide variety of both micro- and macro-scale benchmarks. In total, this report represents approximately 330 hours of machine time. Optane DC memory occupies a tier in-between SSDs and DRAM. It has higher latency (346 ns) than DRAM but lower latency than an SSD. Unlike DRAM, its bandwidth is asymmetric with respect to access type: for a single Optane DC PMM, its max read bandwidth is 6.6 GB/s, whereas its max write bandwidth is 2.3 GB/s.
