There is a trend towards smaller, more mobile devices, and they bring tight constraints on the resource sizes they can support. Shane demonstrates the significant progress that ICU4X has made towards reaching its goal of operating in resource-constrained environments. ICU4X has made available its version 1.0 release in September 2022.

There is a trend towards smaller, more mobile devices, and they bring tight constraints on the resource sizes they can support. Shane demonstrates the significant progress that ICU4X has made towards reaching its goal of operating in resource-constrained environments. ICU4X has made available its version 1.0 release in September 2022. As new programming languages and new devices continue to be created, the problem of not having new, easy solutions for good internationalization grows, too. Despite the audacious scope of the problem, ICU4X is proactively addressing the problem so that implementing internationalization best practices can be easily achieved anywhere. Show less

JavaScript remains one of the most widely used programming languages, and its popularity continues to grow. Today, it is used not only in web browsers, but also on mobile devices, IoT, and cloud services. This is why building great i18n into the ECMAScript standard library is a unique opportunity to have a high impact on the industry. ECMA-402, the Intl object for ECMAScript, is standardized by TC39-TG2. In this presentation, delegates on TC39-TG2 will introduce the latest updates on ECMA-402… Show more

JavaScript remains one of the most widely used programming languages, and its popularity continues to grow. Today, it is used not only in web browsers, but also on mobile devices, IoT, and cloud services. This is why building great i18n into the ECMAScript standard library is a unique opportunity to have a high impact on the industry. ECMA-402, the Intl object for ECMAScript, is standardized by TC39-TG2. In this presentation, delegates on TC39-TG2 will introduce the latest updates on ECMA-402 and how you can leverage it in your applications. We will cover the latest options for the formatting of dates, times, numbers, currencies, units, and durations; Unicode collation and segmentation; display names; plural rules; and what is next for the standards body.

ICU4X is a new Unicode Consortium effort bringing i18n to modern platforms and devices.

Conceived at IUC 43, introduced at IUC 44, and now approaching public beta, ICU4X delivers ECMA-402 APIs, dynamic locale data, and ow resource usage in a composable, modular way using Rust, with interfaces to other programming languages. In this presentation, we will introduce the design principles of ICU4X, how to deliver locale data, and how to use it in multiple programming languages.

We will show how to take advantage of ICU4X's modularity to reduce binary size, and how ICU4X stacks up on memory and performance benchmarks. Show less

JavaScript is a platform available not only in web browsers but also on mobile devices, IoT, cloud services, and many others. This means that building i18n features into JavaScript (formally ECMAScript) has a high impact on i18n library availability. ECMA 402 is a subcommittee of TC39 that standardizes features for the Intl object of ECMAScript. The subcommittee’s work has previously included Intl.DateTimeFormat, Intl.NumberFormat, Intl.Collator, and others. This presentation will give an… Show more

ICU4C binary distributions and ICU4J jar files have a large footprint, exceeding 11 MiB compressed size, largely due to the footprint of locale data. While this is usually fine for server-side applications, the increased overhead for application downloads and binary distributions is problematic for many users doing client-side i18n on smartphones and IoT devices. The data footprint of ICU is often a blocker for users adopting ICU, resulting in those products having subpar i18n support. ICU 64… Show more

ICU4C binary distributions and ICU4J jar files have a large footprint, exceeding 11 MiB compressed size, largely due to the footprint of locale data. While this is usually fine for server-side applications, the increased overhead for application downloads and binary distributions is problematic for many users doing client-side i18n on smartphones and IoT devices. The data footprint of ICU is often a blocker for users adopting ICU, resulting in those products having subpar i18n support. ICU 64 introduces the ICU Data Build Tool, an approach for optimizing high-footprint data bundles to include only the locales and features users need in their ICU build. This session will be a deep-dive into how ICU locale data works and how to leverage the ICU Data Build Tool to reduce your locale data footprint. Show less

Many Burmese speakers use fonts and keyboards that generate a "font hack" encoding called Zawgyi. This non-standard use of Myanmar-script code points breaks text matching, sorting, spell checking, word wrapping, and other text processing.

We will show examples of how Zawgyi impacts Google products and describe approaches for processing Zawgyi text, including detection and conversion to standard Unicode via open-source libraries. We invite discussion of how the technical community can… Show more

We will show examples of how Zawgyi impacts Google products and describe approaches for processing Zawgyi text, including detection and conversion to standard Unicode via open-source libraries. We invite discussion of how the technical community can best serve users of both the Burmese language as well as users of other languages that share the Myanmar script (such as Mon, Shan and Karen).

How many ways can you display a number like "1234" in different locales around the world? Did you know that Unicode has digits in over two dozen non-Latin scripts? What's the difference between Arabic digits and the Arabic numbering system? When parsing a string such as "987.789", is the period a decimal separator or a grouping separator? How do you display currencies that have different rounding rules? This presentation will have two parts. The first part will provide background, answering the… Show more

How many ways can you display a number like "1234" in different locales around the world? Did you know that Unicode has digits in over two dozen non-Latin scripts? What's the difference between Arabic digits and the Arabic numbering system? When parsing a string such as "987.789", is the period a decimal separator or a grouping separator? How do you display currencies that have different rounding rules? This presentation will have two parts. The first part will provide background, answering the above questions and discussing how numerals are encoded in the Unicode standard. The second part will discuss formatting localized numbers in ICU, with a focus on new features added in ICU 60. You will learn how ICU formats numbers under the hood, how to write a decimal formatting skeleton string, and best practices on using the new number formatting API. Show less

Abstract: Controlling molecule-surface interactions is key for chemical applications ranging from catalysis to gas sensing. We present a framework for accelerating the search for the global minimum on potential surfaces, corresponding to stable adsorbate-surface structures. We present a technique using Bayesian inference that enables us to predict converged density functional theory potential energies with fewer self-consistent field iterations. We then discuss how this technique fits in with… Show more

Abstract: Controlling molecule-surface interactions is key for chemical applications ranging from catalysis to gas sensing. We present a framework for accelerating the search for the global minimum on potential surfaces, corresponding to stable adsorbate-surface structures. We present a technique using Bayesian inference that enables us to predict converged density functional theory potential energies with fewer self-consistent field iterations. We then discuss how this technique fits in with the Bayesian Active Site Calculator, which applies Bayesian optimization to the problem. We demonstrate the performance of our framework using a hematite (Fe2O3) surface and present the adsorption sites found by our global optimization method for various simple hydrocarbons on the rutile TiO2 (110) surface.

Abstract: We present a novel application of Bayesian optimization to the field of surface science: rapidly and accurately searching for the global minimum on potential energy surfaces. Controlling
molecule–surface interactions is key for applications ranging from environmental catalysis to gas
sensing. We present pragmatic techniques, including exploration/exploitation scheduling and a
custom covariance kernel that encodes the properties of our objective function. Our method, the
Bayesian Active Site Calculator (BASC), outperforms differential evolution and constrained minima
hopping — two state-of-the-art approaches — in trial examples of carbon monoxide adsorption
on a hematite substrate, both with and without a defect. Show less
