Yesterday we announced something I believe is a game-changer: WSO2 Stratos. What is Stratos?

WSO2 Stratos is a complete SOA and developer platform offered as a self-service, multi-tenant, elastic runtime for private and public cloud infrastructures.

What that means is that our complete SOA platform - now enhanced with Tomcat and Webapp support - is available as a  "cloud native" runtime that you can either use on the Web (yes - you can try it out right now), on Amazon VPC, or on your own internal private cloud based on Ubuntu Enterprise Cloud, Eucalyptus and (coming soon) vmWare vSphere. It is a complete Platform-as-a-Service for private and public clouds.

I'll be writing more about Stratos over the coming weeks and months, and I'll also provide links and tweets to other Stratos blogs, but in this blog I want to simply answer three questions:

1. I'm already talking to {vmWare, Eucalyptus, Ubuntu, Savvis, Joyent} about private cloud - what does WSO2 add that they don't have?
2. What is the difference between Stratos and the Cloud Images that WSO2 already ships?
3. Why would I choose WSO2 over the other vendors offering Platform-as-a-Service?

In order to answer the first question, lets look at the cloud computing space, which is most easily divided up into:

• Infrastructure-as-a-Service (IaaS): this is where Amazon, Eucalyptus, vmWare, Saavis and Joyent play
• Platform-as-a-Service (PaaS): Google App Engine, vmForce, Tibco Silver and now WSO2 Stratos play in this space.
• Software-as-a-Service (SaaS): Google Apps, Google Mail, Microsoft Office Live, Salesforce, SugarOnDemand - these and many more make up the SaaS category.

To generalize wildly, most people talking about public cloud today are talking about SaaS. And most people talking about private cloud today are talking about IaaS.

SaaS is fantastic for quick productivity and low cost. WSO2 uses Google Apps, Sugar on Demand and several other SaaS apps. But SaaS doesn't create competitive advantage. Mule also uses Google Apps. They may well use Salesforce. SaaS cannot produce competitive advantage because your competitors get access to exactly the same low-cost services you do. In order to create competitive advantage you need to build as well as buy. For example, we use our Mashup Server together with our Sugar Business Messaging Adapter to provide insight and management of our pipeline that goes beyond what Sugar offers.

IaaS is of course a great basis to build apps. But it's just infrastructure. Yes - you get your VM hosted quicker. But someone has to create a useful VM. And that is where PaaS comes in. PaaS is how to speed up cloud development.

What does Stratos give you on top of an IaaS? It gives you an Application Server, Registry, Identity Server, Portal, ESB, Business Activity Monitor and Mashup Server. And it gives you these as-a-Service: completely self-service, elasticly scalable, and granularly metered and monitored. Someone in your team needs an ESB - they can provision one for themselves instantly. And because it's multi-tenant, it costs nothing to run until it gets used. How do you know how it's used? The metering and monitoring tells you exactly how much each tenant uses.

2. What is the difference between Stratos and the existing WSO2 Cloud Images?

The cloud images we started shipping in December are not Cloud Native. Stratos is Cloud Native. In practice, this means that when you log into Stratos (go on try it now) you can instantly provision your own domain, together with a set of Stratos services. This saves memory - instead of allocating a new VM and minimum half a gigabyte of memory to each new server you get a new ESB with zero extra memory cost. And it's much easier. The new ESB will automatically be governed and monitored. It's automatically elastically clustered.

3. Why would I choose WSO2 over other PaaS vendors?

Firstly, if you look at PaaS as a whole there is a huge divide between Public PaaS and Private PaaS. The public PaaS vendors simply don't offer private options. You can't run force.com or Google App Engine applications internally, even if you want to. WSO2 bridges that gap with a PaaS you can use in the public Web, on a virtual private cloud, or on premises.

The second big differentiator between WSO2 and the existing PaaS offerings is the architecture. Mostly PaaS is a way of building webapps. WSO2 offers a complete enterprise architecture - governance, business process, integration, portal, identity and mashups. And we support the common Enterprise Programming Model (not just Java, WebApp, JAX-WS, but also BPEL, XSLT, XPath, Google Gadgets, WSDL, etc). The only other PaaS that I know of that offers a full Enterprise architecture is Tibco Silver.

The third and most important differentiator is about lock-in. Software vendors love lock-in - and Cloud vendors love it even more. So if you code to Google App Engine, you are tied into Google's identity model, Google's Bigtable, etc. If you code to force.com or vmForce - you are tied to force's infrastructure services. If you code to Tibco Silver, you are tied to Tibco. WSO2 fights this in three ways:

• No code lock-in: we use standards-based coding (WAR, JAX-WS, POJO) and Stratos is 100% Apache License Open Source.
• No model lock-in: we use standards-based services: 
• Identity is based on OpenID, OAuth, XACML, WS-Trust
• Registry is based on AtomPub and REST
• Business Process is based on BPEL, etc
• No hosting lock-in: you can take you apps and data from our public PaaS and re-deploy internally or on your own virtual private cloud anytime you like.

I hope you found this a useful introduction to Stratos. If you want more information, contact me paul@wso2.com, or check out the Stratos website or code.

Computer Supported Collaborative Learning could highly impact education around the world if the proper Collaborative Learning tools are set in place. In this paper we describe the design of a collaborative learning activity for teaching Chemistry to Chilean students. We describe a PDA-based software tool that allows teachers to create workgroups in their classrooms in order to work on the activity. The developed software tool has three modules: one module for teachers, which runs on a PC and lets them create the required pedagogical material; second, there is a PDA module for students which lets them execute the activity; finally, a third module allows the teacher set workgroups and monitor each workgroup during the activity.

This paper puts forward a verification method for compound purposes and compound reasons to be used during purpose limitation.

When it is absolutely necessary to collect privacy related information, it is essential that privacy enhancing technologies (PETs) protect access to data - in general accomplished by using the concept of purposes bound to data. Compound purposes and reasons are an enhancement of purposes used during purpose limitation and binding and are more expressive than purposes in their general form. Data users specify their access needs by making use of compound reasons which are defined in terms of (compound) purposes. Purposes are organised in a lattice with purposes near the greatest lower bound (GLB) considered weak (less specific) and purposes near the least upper bound (LUB) considered strong (most specific).

Access is granted based on the verification of the statement of intent (from the data user) against the compound purpose bound to the data; however, because purposes are in a lattice, the data user is not limited to a statement of intent that matches the purposes bound to the data exactly - the statement can be a true reflection of their intent with the data. Hence, the verification of compound reasons against compound purposes cannot be accomplished by current published verification algorithms.

Before presenting the verification method, compound purposes and reasons, as well as the structures used to represent them, and the operators that are used to define compounds is presented. Finally, some thoughts on implementation are provided.

Siemens is well known for ambitious efforts in knowledge management, providing a series of innovative tools and applications within the intranet. References@BT is such a web-based application with currently more than 7,300 registered users from more than 70 countries. Its goal is to support the sharing of knowledge, experiences and best-practices globally within the Building Technologies division. Launched in 2005, References@BT features structured knowledge references, discussion forums, and a basic social networking service. In response to use demand, a new microblogging service, tightly integrated into References@BT, was implemented in March 2009. More than 500 authors have created around 2,600 microblog postings since then. Following a brief introduction into the community platform References@BT, we comprehensively describe the motivation, experiences and advantages for an organization in providing internal microblogging services. We provide detailed microblog usage statistics, analyzing the top ten users regarding postings and followers as well as the top ten topics. In doing so, we aim to shed light on microblogging usage and adoption within a globally distributed organization.

In this paper we present an approach to improving navigability of a hierarchically structured Web content. The approach is based on an integration of a tagging module and adoption of tag clouds as a navigational aid for such content. The main idea of this approach is to apply tagging for the purpose of a better highlighting of cross-references between information items across the hierarchy. Although in principle tag clouds have the potential to support efficient navigation in tagging systems, recent research identified a number of limitations. In particular, applying tag clouds within pragmatic limits of a typical user interface leads to poor navigational performance as tag clouds are vulnerable to a so-called pagination effect. In this paper, a solution to the pagination problem is discussed, implemented as a part of an Austrian online encyclopedia called Austria-Forum, and analyzed. In addition, a simulation-based evaluation of the new algorithm has been conducted. The first evaluation results are quite promising, as the efficient navigational properties are restored.

Les pycnogonides, une espèce marine apparentée aux araignées, peuvent faire repousser des parties du corps après amputation, et pas seulement de simples membres, selon une étude publiée lundi, ouvrant la voie à de nouvelles découvertes sur la régénération.

"Personne ne s'attendait à cela", a déclaré Gerhard Scholtz de la prestigieuse université Humboldt à Berlin, et l'un des auteurs principaux de cette étude parue dans la revue Proceedings of the National Academy of Sciences. "Nous avons été les premiers à démontrer que c'était possible", a-t-il ajouté. Il est connu qu'une multitude d'espèces d'arthropodes tels que les mille-pattes, les araignées ou d'autres insectes peuvent faire repousser une patte après l'avoir perdue.

"Les crabes peuvent même se débarrasser automatiquement de leurs membres s'ils sont attaqués", a déclaré Gerhard Scholtz, précisant: "ils les remplacent par un nouveau membre". Ce que les chercheurs ont découvert à travers leurs expériences avec ces minuscules créatures à huit pattes, est qu'elles sont capables de régénérer même d'autres parties du corps. Pour l'étude, ils ont amputé différents membres et parties postérieures du corps de 23 pycnogonides juvéniles et adultes, et ont observé les résultats.

Repousse d'un corps à partir de seulement quelques cellules

Aucune régénération de parties du corps n'a été constatée dans les spécimens adultes, mais certains étaient toujours en vie après deux ans. Les spécimens juvéniles, en revanche, ont connu une régénération complète ou quasi-complète des parties du corps manquantes, y compris l'intestin postérieur, l'anus, la musculature, et certaines parties d'organes génitaux.

A long terme, 90% des pycnogonides ont survécu, et 16 spécimens juvéniles ont effectué leur mue par la suite au moins une fois. La régénération postérieure a ainsi été constatée chez 14 des spécimens juvéniles tandis qu'aucun des spécimens adultes n'a mué ou ne s'est régénéré. Les capacités de régénération varient à travers le règne animal.

Les vers plats, par exemple, peuvent faire repousser leur corps à partir de seulement quelques cellules. Les vertébrés, dont les hommes, n'ont quasiment aucune capacité de régénération à l'exception de quelques espèces comme les lézards, qui peuvent faire repousser leurs queues.

Selon Gerhard Scholz, les résultats de l'étude ouvrent de nouvelles voies de recherche dans le domaine. "Une multitude d'espèces différentes peuvent être testées de cette manière", dit-il, ce qui pourrait permettre de comparer les mécanismes de régénération. "Au bout du compte, peut-être que les mécanismes que nous découvrons chez les arthropodes nous aiderons dans les traitements médicaux après la perte d'un membre, d'un doigt, etc... chez les humains", espère le chercheur.

(Belga) Quatre membres de la milice d'extrême droite "Oath Keepers" ont été reconnus coupables lundi de sédition pour leur rôle dans l'assaut du Capitole, à l'issue du second procès organisé sur ce chef d'accusation extrêmement rare.

Depuis l'attaque du 6 janvier 2021, plus de 950 partisans de l'ex-président républicain Donald Trump ont été arrêtés et inculpés pour avoir semé le chaos dans le siège de la démocratie américaine. Parmi eux, seuls 14 militants de groupuscules d'extrême droite - neuf membres des "Oath Keepers" et cinq "Proud Boys" - ont été accusés de "sédition", un chef passible de 20 ans de prison qui implique d'avoir planifié l'usage de la force pour s'opposer au gouvernement. Faute de place suffisante dans le tribunal fédéral de Washington, la justice a organisé le procès des Oath Keepers, accusés de s'être entraînés et armés pour l'occasion, en deux temps. Un premier procès s'est conclu fin novembre par un verdict mitigé: le fondateur de cette milice, Stewart Rhodes, et un responsable local ont été déclarés coupables de sédition, mais leurs trois co-accusés ont été acquittés sur ce chef. Lundi, à l'issue du second procès, les jurés ont jugé coupables les quatre derniers Oath Keepers, des hommes âgés de 38 à 64 ans décrits comme de dangereux "traîtres" par l'accusation, mais comme des "fanfarons" par leurs avocats. Le procès des Proud Boys, dont leur leader Enrique Tarrio, s'est ouvert en décembre et était toujours en cours lundi, dans le même tribunal. (Belga)

(Belga) Sept personnes ont été tuées lundi lors d'une double fusillade près de San Francisco, en Californie, ont indiqué les médias américains sur la base des déclarations de la police locale.

Le suspect a été arrêté, a annoncé sur Twitter le bureau du shérif du comté de San Mateo, qui comprend la ville de Half Moon Bay où ont eu lieu les drames. "Il n'y a plus de danger pour la population à cette heure", a-t-il assuré. Les deux fusillades sont intervenues dans des exploitations agricoles proches l'une de l'autre, ont précisé les médias. Cette nouvelle tuerie intervient moins de 48 heures après qu'un tireur a tué 11 personnes dans un club de danse près de Los Angeles. (Belga)

Smart cities research is growing all over the world seeking to understand the effect of smart cities from different angles, domains and countries. The aim of this study is to analyse how the smart city ICTs (e.g., big data analytics, AI, IoT, cloud computing, smart grids, wireless communication, intelligent transportation system, smart building, e-governance, smart health, smart education and cyber security) are related to government. services and society welfare from the perspective of China. This research confirmed a positive correlation of smart city ICTs to e-Govt. Services (e-GS). On the other hand, the research showed a positive influence of smart city ICTs on society's welfare. These findings about smart cities and ICTs inform us how the thought paradigm to smart technologies can cause the improvement of e-GS through economic development, job creation and social welfare. The study offers different applications of the theoretical perspectives and the management perspective which are significant to building a society during recent technologised era.

The confluence of the internet of things (IoT) with smart grids has ushered in a paradigm shift in energy management, promising unparalleled efficiency, economic robustness and unwavering reliability. However, this integrative evolution has concurrently amplified the grid's susceptibility to cyber intrusions, casting shadows on its foundational security and structural integrity. Machine learning (ML) and deep learning (DL) emerge as beacons in this landscape, offering robust methodologies to navigate the intricate cybersecurity labyrinth of IoT-infused smart grids. While ML excels at sifting through voluminous data to identify and classify looming threats, DL delves deeper, crafting sophisticated models equipped to counteract avant-garde cyber offensives. Both of these techniques are united in their objective of leveraging intricate data patterns to provide real-time, actionable security intelligence. Yet, despite the revolutionary potential of ML and DL, the battle against the ceaselessly morphing cyber threat landscape is relentless. The pursuit of an impervious smart grid continues to be a collective odyssey. In this review, we embark on a scholarly exploration of ML and DL's indispensable contributions to enhancing cybersecurity in IoT-centric smart grids. We meticulously dissect predominant cyber threats, critically assess extant security paradigms, and spotlight research frontiers yearning for deeper inquiry and innovation.

File transfer is always handled by a separate service, sometimes it is a third-party service in videoconferencing. When sending files during a video session, file data flow and video stream are independent of each other. Encryption is a mature method to ensure file security. However, it still has the chance to leave footprints on the intermediate forwarding machines. These footprints can indicate that a file once passed through, some protocol-related logs give clues to the hackers' later investigation. This work proposes a file-sending scheme through the video stream using blockchain and steganography. Blockchain is used as a file slicing and linkage mechanism. Steganography is applied to embed file pieces into video frames that are continuously generated during the session. The scheme merges files into the video stream with no file transfer protocol use and no extra bandwidth consumed by the file to provide trackless file transmission during the video communication.

At present, there is a need for an authentic and fast approach to certificate verification. Which verifies and authenticates the certificates to reduce the extent of duplicity and time. An academic certificate is significant for students, the government, universities, and employers. Academic credentials play a vital role in the career of students. A few people manipulate academic documents for their benefit. There are cases identified where people produced fake academic certificates for jobs or higher education admission. Various research works are developing a secure model to verify genuine academic credentials. This research article proposed a new security model which contains several security algorithms such as timestamps, hash function, digital signature, steganography, and blockchain. The proposed model issues secure digital academic certificates. It enhanced security measures and automated educational certificate verification using blockchain technology. The advantages of the proposed model are automated, cost-effective, secured, traceable, accurate, and time-saving.

The current study has outlined slow fashion (SF) research trends and created a future research agenda for this field. It is a thorough analysis of the literature on slow fashion. Numerous bibliometric features of slow fashion have been discussed in the paper. This study comprises 182 research articles from the Scopus database. The database was utilised for bibliometric analysis. To identify certain trends in the area of slow fashion, a bibliometric study is done. For bibliometric analysis, the study employed R-software (the Biblioshiny package). Here, VOSviewer software is used to determine the co-occurrence of authors, countries, sources, etc. The study has outlined the gap that still exists in the field of slow fashion. Here, the research outcome strengthens the domain of slow fashion for sustainable consumption. The study findings will be useful for policymakers, industry professionals, and researchers.

This systematic literature study employed bibliometric analysis to identify workplace mindfulness-related methods and practices in literature published from 2000 to 2020 by leading nations, institutions, journals, authors, and keywords. We also assessed the impact of workplace mindfulness research papers. Scopus analysis tools provided a literature report for 638 Scopus articles used in the study. Using VOSviewer, leading nations, institutions, articles, authors, journals, and keyword co-occurrence network maps were constructed. PRISMA was used to identify 56 publications to recognise workplace mindfulness literature's significant achievements. The research's main contribution is a deep review of neurological mindfulness and psychological measuring tools as workplace mindfulness tool categories. The study is the first to use the PRISMA technique to capture the essential contributions of workplace mindfulness papers from 2000 to 2020.

Although artificial intelligence provides a new method to gather, process, analyse data, generate insights, and offer customised solutions, such methods could change how marketers deal with customers, and there is a lack of literature to portray the application of artificial intelligence in marketing. This study aims to recognise and portray the use of artificial intelligence from a marketing standpoint, as well as to provide a conceptual framework for the application of artificial intelligence in marketing. This study uses a systematic literature review analysis as a research method to achieve the aims. Data from 142 articles were extracted from the Scopus database using relevant search terms for artificial intelligence and marketing. The systematic review identified significant usage of artificial intelligence in conversational artificial intelligence, content creation, audience segmentation, predictive analytics, personalisation, paid ads, sales forecasting, dynamic pricing, and recommendation engines and the bibliometric analysis produced the trend in co-authorship, citation, bibliographic coupling, and co-citation analysis. Practitioners and academics may use this study to decide on the marketing area in which artificial intelligence can be invested and used.

Supply chain management practices are vital for success and survival in today's competitive Indian retail market. The advent of COVID-19 pandemic necessitates a digital disruption in retail supply chain management centred on efficient technology like blockchain in order to enhance supply chain performance. The present research aims to decipher the nature of associations between supply chain management practices, blockchain technology adoption and supply chain performance in retail firms. The research is based on primary survey of specific food and grocery retailers operating on a supermarket format stores in two Indian cities. The findings pointed towards the presence of significant and positive association of all the constructs with each other. Moreover, the mediating role of blockchain technology adoption was also revealed, i.e., it partially mediates the effects of supply chain management practices on supply chain performance.

Food quality is defined as a collection of properties that differentiate each unit and influences acceptability degree of food by users or consumers. Owing to the nature of food, food quality prediction is highly significant after specific periods of storage or before use by consumers. However, the accuracy is the major problem in the existing methods. Hence, this paper presents a BEFA_DRNN approach for accurate food quality prediction using dairy products. Firstly, input data is fed to data normalisation phase, which is performed by min-max normalisation. Thereafter, normalised data is given to feature fusion phase that is conducted employing DNN with Canberra distance. Then, fused data is subjected to data augmentation stage, which is carried out utilising oversampling technique. Finally, food quality prediction is done wherein milk is graded employing DRNN. The training of DRNN is executed by proposed BEFA that is a combination of BES and FA. Additionally, BEFA_DRNN obtained maximum accuracy, TPR and TNR values of 93.6%, 92.5% and 90.7%.

Along with amazing advancements in the field of digital payments, this article seeks to provide a summary of research undertaken over the last four decades and to suggest areas in need of additional study. This study employs a two-pronged technique for analysing its data. The first is concerned with performance analysis, and the second with science mapping. The study uses the apps VOS viewer and R-studio to do bibliometric data analysis. From 1982 until May 2022, the most trustworthy database, Scopus, is used to compile a database of 923 publications The findings of this study identify the scope of current research interest, which is explored with critical contributions from a variety of authors, journals, countries, affiliations, keyword analysis, citation analysis, co-citation analysis, and bibliometric coupling, as well as a potential research direction for further investigation in this emerging field.

The proliferation of technology and communication has resulted in increased digitalisation that includes digital payments. This study is aimed at unravelling the relationship between awareness of individuals about the digital payment system and customer satisfaction with digital payments. Two models were developed in this study. First model considers awareness → usage pattern → customer satisfaction. Second model considers usage pattern → customer satisfaction → perception of digital payments. These two alternative models were tested by collecting data from 507 respondents in southern India was analysed using the structural equation modelling. The results indicate that usage pattern acted as a mediator between awareness and satisfaction, and satisfaction acted as a mediator between usage pattern and consumers' perception of digital payments. The implications for theory and practice are discussed.

In the era of big data, enterprises have accumulated a large amount of research and development data. Effective management of their precipitated data and safe sharing of data can improve the collaboration efficiency of research and development personnel, which has become the top priority of enterprise development. This paper proposes to use blockchain technology to assist the collaboration efficiency of enterprise R&D personnel. Firstly, the multi-chain blockchain platform is used to realise the data sharing of internal data of enterprise R&D data department, project internal data and enterprise data centre, and then the process of construction of multi-chain structure and data sharing is analysed. Finally, searchable encryption was introduced to achieve data retrieval and secure sharing, improving the collaboration efficiency of enterprise research and development personnel and maximising the value of data assets. Through the experimental verification, the multi-chain structure improves the collaboration efficiency of researchers and data security sharing.

With the development of urban construction, its spatial evolution is also influenced by behavioural actors such as enterprises, residents, and environmental factors, leading to some decision-making behaviours that are not conducive to urban public space and environmental design. At the same time, some cities are vulnerable to various factors such as distance factors, transportation factors, and human psychological factors during the construction of public areas, resulting in a decline in the quality of urban human settlements. Urban public space is the guarantee of urban life. For this, in order to standardise urban public space and improve the quality of urban living environment, the standardisation of the environment of urban public space is required. The rapid development of intelligent algorithms and fuzzy control provides technical support for the environmental design of urban public spaces. Through the modelling of intelligent algorithms and the construction of fuzzy space, it can meet the diverse.

Elections hold immense significance in shaping the leadership of a nation or organisation, serving as a pivotal moment that influences the trajectory of the entity involved. Despite their centrality to modern democratic systems, elections face a significant hurdle: widespread mistrust in the electoral process. This pervasive lack of confidence poses a substantial threat to the democratic framework, even in the case of prominent democracies such as India and US, where inherent flaws persist in the electoral system. Issues such as vote rigging, electronic voting machine (EVM) hacking, election manipulation, and polling booth capturing remain prominent concerns within the current voting paradigm. Leveraging blockchain for electronic voting systems offers an effective solution to alleviate the prevailing apprehensions associated with e-voting. By incorporating blockchain into the electoral process, the integrity and security of the system could be significantly strengthened, addressing the current vulnerabilities and fostering trust in democratic elections.
