I Have Often Mused About How the Architecture of the Cpus We Use Influ
Musings RIK FARROWEDITORIAL Rik is the editor of ;login:. have often mused about how the architecture of the CPUs we use influ- [email protected] ences the way our operating systems and applications are designed. A I book I reviewed in this issue on the history of computing managed to cement those ideas in my head. Basically, we’ve been reprising time-sharing systems since the mid-60s, whereas most systems serve very different pur- poses today. Along the way, I also encountered a couple of interesting data points, via pointers from friends who have been influencing me. One was Halvar Flake’s CYCON 2018 talk [1], and another was about a new OS project at Google. The opinion piece by Jan Mühlberg and Jo Van Bulck that appears in this issue influenced me as well, as it describes a CPU feature that, among other things, could block the use of gadgets in return-oriented programming (ROP). Flake explained that much of our current problems with security have to do with cheap com- plexity. Even though a device, like a microwave oven or intravenous drip-rate controller, only requires a PIC (Programmable Interrupt Controller), it may instead have a full-blown CPU running Windows or Linux inside it. CPUs are, by design, flexible enough to model any set of states, making them much more complex than what is needed inside a fairly simple device. Designers instead choose to use a full-blown CPU, usually with an OS not designed to be embedded, to model the states required. Vendors do this because many more people under- stand Windows or Linux programming than know how to program a PIC. -

November 2013 ---International Rock Gardener--- November 2013
International Rock Gardener ISSN 2053-7557 Number 47 The Scottish Rock Garden Club November 2013 ---International Rock Gardener--- November 2013 As most gardeners know, taxonomic changes can be fraught with controversy, for any number of reasons! Take for instance the name of the beautiful endemic gesneriad from Mount Olympus, Jankaea heldreichii – still ‘unresolved’ in the Kew Plant List. In 1993 a paper by Christian Feuillet detailed the need to change the names of various Jankaea hybrids to comply with the Jancaea name. Z.Z. writes: “We Czechs do not like the deformation of the good name Jankaea to Jancaea, because the honoured Hungarian botanist had the name Janka and not Janca.” A search around the internet will show that many others also prefer this form – including Josef Halda, who described several such hybrids, some of which are among plants from the Gesneriaceae featured this month. Cover: Ramonda nathaliae on limestone south of Skoplje in Macedonia, picture by Z.Z. ---Plant Portraits--- Two New Intergeneric Hybrids in the Family Gesneriaceae by Josef.J.Halda, drawings by Jarmila Haldová, pictures by Z.Z. (From Acta Mus. Richnoviensis (Sect. natur.), 19(3–4): 49-54) In the spring of 1973 I received from the Geneva-based Aymon Correvon* a plant named Jankaea vandedemii, resembling Jankaea heldreichii with almost globose leaves, which later bloomed with lavender blue flowers, though only shallowly campanulate ones. In response to my question on the origin of the plant he answered that he got it from Mr. Vandedem, Holland, who is supposedly also the author of this hybrid, the parents of which are the Greek Jankaea heldreichii as the mother plant and the father is the Pyrenean Ramonda myconii. -
Lamiales – Synoptical Classification Vers
Lamiales – Synoptical classification vers. 2.6.2 (in prog.) Updated: 12 April, 2016 A Synoptical Classification of the Lamiales Version 2.6.2 (This is a working document) Compiled by Richard Olmstead With the help of: D. Albach, P. Beardsley, D. Bedigian, B. Bremer, P. Cantino, J. Chau, J. L. Clark, B. Drew, P. Garnock- Jones, S. Grose (Heydler), R. Harley, H.-D. Ihlenfeldt, B. Li, L. Lohmann, S. Mathews, L. McDade, K. Müller, E. Norman, N. O’Leary, B. Oxelman, J. Reveal, R. Scotland, J. Smith, D. Tank, E. Tripp, S. Wagstaff, E. Wallander, A. Weber, A. Wolfe, A. Wortley, N. Young, M. Zjhra, and many others [estimated 25 families, 1041 genera, and ca. 21,878 species in Lamiales] The goal of this project is to produce a working infraordinal classification of the Lamiales to genus with information on distribution and species richness. All recognized taxa will be clades; adherence to Linnaean ranks is optional. Synonymy is very incomplete (comprehensive synonymy is not a goal of the project, but could be incorporated). Although I anticipate producing a publishable version of this classification at a future date, my near- term goal is to produce a web-accessible version, which will be available to the public and which will be updated regularly through input from systematists familiar with taxa within the Lamiales. For further information on the project and to provide information for future versions, please contact R. Olmstead via email at [email protected], or by regular mail at: Department of Biology, Box 355325, University of Washington, Seattle WA 98195, USA. -

Pollen tube growth rates (PTGRs) of angiosperms are exceptionally rapid, a pattern 25 attributed to more effective haploid selection under stronger pollen competition. Paradoxically, 26 whole genome duplication (WGD) has been common in angiosperms but rare in gymnosperms. -
Google, Where Are You Taking Fuchsia and Should Android Care? 15 August 2016, by Nancy Owano
Google, where are you taking Fuchsia and should Android care? 15 August 2016, by Nancy Owano Android Police."There's a massive ecosystem of operating systems designed for embedded hardware, and Google may be working on their own." Why would they call it Fuchsia? "When you begin to dig deeper into Fuchsia's documentation, everything starts to make a little more sense," said Davenport. As with the Linux-Android relationship, the Magenta kernel powers the larger Fuchsia operating system. Davenport offered some details about the rest of the system: "Google is using Flutter for the user interface, as well as Dart as the primary (Tech Xplore)—Projects or experiments at big programming language. The icing on the cake is technology companies go either way. Either they Escher, a renderer that supports light diffusion, soft fail to materialize into actual products but turn up shadows, and other visual effects, with OpenGL or some interesting lessons learned for company Vulkan under the hood." developers and architects. So where does Fuchsia sit on Google's OS food Those insights might even be re-used for different chain? Right now it is a project on GitHub. This target applications, end of story. The other could go a number of ways, said Davenport. direction is that, down the road in a year or three, the project evolves into something real that the It could turn out that Google treats Fuchsia "like company sells. Samsung treats Tizen OS; a lightweight OS used on hardware not suited for full-blown Android," Question of the month about Google now is which Davenport wrote. -

Choosing React Native for Your Mobile Tech Stack
CHOOSING REACT NATIVE FOR YOUR MOBILE TECH STACK The all-in-one guide for CEOs and Product Owners When Facebook developers first introduced ReactJS to the world at the 2013 JSConf event, they could hardly predict how this announcement would impact web app development. Two years later, inspired by the library’s impressive growth, the company made another in-house project, React Native, available to the public by releasing it on GitHub. 26th March, the day when React Native joined the open-source domain, set a milestone for the development of mobile applications. 1 Today, with nearly 1,800 contributors and more than 15K commits in 89 branches, React Native (RN) is one of the most popular GitHub repositories. What exactly is React Native? Who can benefit from it? How to develop your first mobile app with RN? These are just some of the questions we will answer in this all-in-one guide to the React Native framework. Why did we create Who should read our this page? guide?
