With an intention to provide a free internet resource of chemistry related data for the community, ChemSpider provides an online database of chemical compounds, reaction syntheses and related data. Members of the community can contribute to the database via the deposition of chemical structures, synthesis procedures and analytical data. Data are also aggregated from many other depositors, at present over 400 data sources. The aggregation of data associated with over 25 million chemical compounds does not come without data quality issues. By engaging the community to curate the data the quality continues to improve on a daily basis. The presentation will provide an overview of our ongoing efforts to expand and curate the database. Using a combination of game-based and recognition systems as well as our dependence on societal giveaway by the community ChemSpider continues its path to become a high quality resource and foundation for the semantic web for chemistry.

ChemSpider is a free access website for chemists built with the intention of providing a structure centric community for chemists. It was developed to index available sources of chemical structures and their associated data into a single searchable repository and making it available to everybody, at no charge. While there are a large number of databases containing chemical compounds and data available online their inherent quality, accuracy and completeness is severely lacking. ChemSpider has provided a platform so that the chemistry community could contribute to improving the quality of data online and expanding the information to include data such as reaction syntheses, analytical data, experimental properties and linkages to other valuable resources. It has grown into a resource containing over 21 million unique chemical structures from over 200 data sources. This presentation will provide an overview of ChemSpider and its value to chemists as a search tool, as a public repository of information and how it can become one of the primary foundations of internet-based chemistry. I will also discuss the vision for ChemSpider and some of the lofty goals we are setting for the system moving forward.

Text Mining for Chemistry and Building a Public Platform for Document Markup The identification of chemical names in documents has provided platforms to enable structure-based searching of patents and mark-up chemistry publications. A natural extension is the ability to make chemistry articles, blog pages, wiki pages and other documents searchable by the extracted chemical structures. The ChemSpider database is built on a database of over 21 million unique chemical entities from close to 200 data sources and provides a rich resource of information for chemists. We will report on our efforts to integrate chemical name extraction with the ChemSpider platform to enable structure searching of Open Access chemistry articles, and online chemistry materials. We will unveil our online document markup platform for chemists to make both their open- and closed-access publications searchable by the language of chemistry – the structure.

The internet now offers access to a myriad of online resources that can be of value to chemists working in the Life Sciences. While finding information online is, in many cases, a simple search away, the accuracy and validity of the associated data and information should be questioned. As more databases and resources are introduced online, and commonly not integrated to other resources, a scientist must perform multiple searches and then undertake the task of meshing and merging data. ChemSpider is a freely accessible online database that has taken on the challenge of meshing together distributed resources across the internet to provide a structure-based hub. It is a crowdsourcing environment hosting over 26 million unique compounds linked out to over 400 data sources. With well defined programming interfaces for integration ChemSpider has been integrated to many commercial and open software packages and is presently serving as the chemistry foundation for the IMI Open PHACTS project.

ChemSpider was developed with the intention of aggregating and indexing available sources of chemical structures and their associated information into a single searchable repository and making it available to everybody, at no charge. There are many tens of chemical structure databases such as literature data, chemical vendor catalogs, molecular properties, environmental data, toxicity data, analytical data etc. and no single way to search across them. Despite the diversity of databases available online their inherent quality, accuracy and completeness is lacking in many regards. ChemSpider was established to provide a platform whereby the chemistry community could contribute to cleaning up the data, improving the quality of data online and expanding the information available to include data such as reaction syntheses, analytical data and experimental properties. ChemSpider has now grown into a database of well over 20 million chemical substances integrated with over 300 disparate data sources, many of these directly supporting the Life Sciences. This presentation will provide an overview of our efforts to improve the quality of data online, to provide a foundation for the semantic web for chemistry and to provide access to a set online tools and services to support access to these data. I will also discuss how ChemSpider is being used to enhance Semantic Publishing in Chemistry at RSC.

A presentation given at #FACCS2010 in Raleigh, North Carolina ChemSpider is an online database of almost 25 million chemical compounds sourced from over 300 different sources including government laboratories, chemical vendors, public resources and publications. Developed with the intention of building community for chemists ChemSpider allows its users to deposit data including structures, properties, links to external resources and various forms of spectral data. Over the past three years ChemSpider has aggregated almost 3000 spectra including Infrared and Raman Data and continues to expand as the community deposits additional data. The majority of spectral data is licensed as Open Data allowing it to be downloaded and reused in presentations, lesson plans and for teaching purposes. This presentation will provide an overview of our efforts to build a structure-indexed online database of spectral data, initiate a call to action to the community to participate in improving this resource for the community at large and discuss how such a resource could be used as the basis of a spectral game to teach students spectral interpretation.

Chemspider hosting linking and curating chemistry data for the community

Royal Society of Chemistry

The Internet is the world’s publicly accessible container for a myriad of resources containing chemistry related data. Whether it be collections of millions of chemical compounds with their associated properties, interactive displays for analytical data, access to publications and patents or tapping into the increasing availability of online computational engines, the web has became the primary enabling technology to source information and data. Scientists collectively applaud and utilize the availability of such resources and an increasing proportion of the community are willing to support these resources by contributing both their data and skills to help curate and validate information on the web. This “crowdsourcing” has started to contribute large amounts of data to the commons and serves has a valuable platform for reference and, potentially, discovery. ChemSpider is one of the chemistry community’s primary online resources and allows scientists to search across 25 million unique chemical compounds linked out to over 400 original data sources and has become a central hub for searching for chemistry-related data. The platform however offers much more to the community and has become a central repository for analytical data, specifically spectra, is a host for community-authored chemical syntheses and facilitates data curation and annotation by any of its users. This presentation will provide an overview of the ChemSpider platform in terms of available data and its efforts to act as a public repository and clearing ground for data curation. We will discuss how such a platform, when coupled with game-based approaches, facilitates both teaching and data validation and will discuss whether public domain resources such as ChemSpider will ultimately become authorities for chemistry.

Laboratories around the world continue to generate immense amounts of data that are non-proprietary and of value to the community. If available these data could dramatically reduce costs by minimizing rework and ultimately facilitating faster research. High quality reference data collections of chemical compound dictionaries, properties and spectra have been generated over many decades. With the advent of social networking tools and platforms such as Wikipedia, the community has an opportunity to contribute. The ChemSpider platform hosted by the Royal Society of Chemistry is a compound centric database with associated data. Already populated with almost 25 million unique compounds the community can deposit and host their own data, and curate and annotate existing data including those generated in Open Notebook Science Efforts. This presentation will provide an overview of progress to date and outline the vision of this community platform for chemistry and ensuring the longevity of chemistry reference data.

The increasing availability of free and open access resources for scientists on the internet presents us with a revolution in data availability. The Royal Society of Chemistry hosts ChemSpider, a free access website for chemists built with the intention of building community for chemists (http://www.chemspider.com/). ChemSpider is an aggregator of chemistry related information, at present over 20 million unique chemical entities linked out to over 300 separate data sources, ChemSpider has taken on the task of both robotically and manually curating publicly available data sources. It is also a public deposition platform where chemists can deposit their own data including novel structures, analytical data, synthesis procedures and host data associated with the growing activities associated with Open Notebook Science. This presentation will examine chemistry on the internet, the dubious quality of what is available and how the ChemSpider crowdsourced curation platform is fast becoming one of the centralized hubs for resourcing information about chemical entities. We will also review our efforts to provide free resources for synthesis procedures, spectral data and structure-based searching of the chemistry literature and how chemists can contribute directly to each of these projects.

This was a presentation I gave to an audience at Nature Publishing Group in New York on May 7th 2009. It's a long presentation and over an hour in length. Not much new here relative to other presentations...just a knitting together of many of the others on here. There is an increasing availability of free and open access resources for scientists to use on the internet. Coupled with an increasing number of Open Source software programs we are in the middle of a revolution in data availability and tools to manipulate these data. ChemSpider is a free access website built with the intention of providing a structure centric community for chemists. As an aggregator of chemistry related information from many sources, at present over 21.5 million unique chemical entities from over 190 separate data sources, ChemSpider has taken on the task of both robotically and manually integrating and curating publicly available data sources. ChemSpider has also provided an environment for users to deposit, curate and annotate chemistry-related information. This has allowed the community to enhance ChemSpider by adding analytical data, associating synthetic pathways and publications and connecting to social networking resources. I will discuss how ChemSpider is fast becoming the premier curated platform and centralized hub for resourcing information about chemical entities and how the platform provides the foundation data for services allowing the analysis of analytical data and collaborative science.

There is an increasing availability of free and open access resources for chemists to use on the internet. Coupled with the increasing availability of Open Source software tools we are in the middle of a revolution in data availability and tools to manipulate these data. ChemSpider is a free access website for chemists built with the intention of providing a structure centric community for chemists. It was developed with the intention of aggregating and indexing available sources of chemical structures and their associated information into a single searchable repository and making it available to everybody, at no charge. There are tens if not hundreds of chemical structure databases such as literature data, chemical vendor catalogs, molecular properties, environmental data, toxicity data, analytical data etc. and no single way to search across them. Despite the fact that there were a large number of databases containing chemical compounds and data available online their inherent quality, accuracy and completeness was lacking in many regards. The intention with ChemSpider was to provide a platform whereby the chemistry community could contribute to cleaning up the data, improving the quality of data online and expanding the information available to include data such as reaction syntheses, analytical data, experimental properties and linking to other valuable resources. It has grown into a resource containing over 21 million unique chemical structures from over 200 data sources. ChemSpider has enabled real time curation of the data, association of analytical data with chemical structures, real-time deposition of single or batch chemical structures (including with activity data) and transaction-based predictions of physicochemical data. The social community aspects of the system demonstrate the potential of this approach. Curation of the data continues daily and thousands of edits and depositions by members of the community have dramatically improved the quality of the data relative to other public resources for chemistry. This presentation will provide an overview of the history of ChemSpider, the present capabilities of the platform and how it can become one of the primary foundations of the semantic web for chemistry. It will also discuss some of the present projects underway since the acquisition of ChemSpider by the Royal Society of Chemistry.

Scientists commonly find themselves in a state of overwhelm in regards to the availability of information accessible to them. The distribution of resources now includes the entire space of the worldwide web, access to primary databases such as CAS and, commonly, a plethora of internally developed systems. While the web has provided improved access to chemistry-related information there has not been an online central resource allowing integrated chemical structure-searching of chemistry databases, chemistry articles, patents and web pages such as blogs and wikis. ChemSpider has built a structure centric community for chemists by providing free access to an online database and collaboration tool for chemists. The online database offers an environment for curating the data on ChemSpider as well as the deposition of chemical structures, analytical data and associated information and provides a significant knowledge base and resource for chemists working in different domains. An overview of present and future capabilities is given.

This our Twelfth semiannual report on the global Cryptocurrency mining industry. Bitcoin is the world’s largest special purpose supercomputer. And it is globally decentralized. Millions of nodes all run the same open-source code to secure the Bitcoin network, create value, and put new transactions onto the distributed ledger. The latest Top500 list has just been announced at the ISC 2024 conference in Hamburg, and once again the Frontier supercomputer with 1.2 Exaflops peak performance is number one on the list. If assigned to SHA-256 hashing, Frontier would provide only the equivalent hash rate of about three cabinets of the latest high-end Bitcoin mining systems, costing less than 0.1% of Frontier’s cost. Michael Saylor, Chairman of MicroStrategy, has pointed out that GPUs are two orders of magnitude slower than the 5-nanometer technology of custom ASICs used for Bitcoin mining today. He makes the point that the Bitcoin network is unassailable by all of the hyperscale computing resources combined in AWS, Google, and Microsoft Azure cloud data centers today.

But you don’t have to tackle everything and can start with the basics and build from there! Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. No matter what tooling is in place, there are still observability fundamentals that developers should know. That’s why I’ve put together a primer on the different telemetry types, when to use them, how to understand the data journey, and what to look for in time series graphs.

Ruby has a lot of standard libraries from Ruby 1.8. I promote them democratically with GitHub today via default and bundled gems. So, I'm working to extract them for Ruby 3.4 continuously and future versions. It's long journey for me. After that, some versions may suddenly happen LoadError at require when running bundle exec or bin/rails, for example matrix or net-smtp. We need to learn what's difference default/bundled gems with standard libraries. In this presentation, I will introduce what's the difficult to extract bundled gems from default gems and the details of the functionality that Ruby's require and bundle exec with default/bundled gems. You can learn how handle your issue about standard libraries.
