Spotique: a New Approach to Local Messaging
This paper describes a new approach to local messaging. Our application combines passive monitoring for smart phones and cloud based messaging for mobile OS (operational system). Passive monitoring can determine the location of mobile subscribers (mobile phones, actually) without the active participation of the users. Mobile users do not need to mark own location on social networks (check-in), they do not need to run on their phones the location track applications. In the same time, Cloud Messaging allows interested parties to directly deliver their information to mobile users who find themselves near a selected point. This is the main content of the service - how to combine the monitoring and notifications.
Smart Cities Software: Customized Messages for Mobile Subscribers
This paper introduces a new way of delivering local messages to mobile subscribers. Our application presents a mashup from passive monitoring for smart phones and cloud-based messaging for mobile operational systems. Passive monitoring can detect the presence of mobile phones without active participation from the users. It does not require prior calibration, nor does it require mobile users to mark their own location on social networks (like traditional check-ins). Mobile users do not need to run location track applications on their phones the. At the same time, a production-based expert system built around cloud messaging allows interested parties to directly deliver their custom information to mobile users in proximity.
Geofence and Network Proximity
Our presentation for ruSMART-2013.
Many of modern location-based services are often based on an area or place as opposed to an accurate determination of the precise location. Geo-fencing approach is based on the observation that users move from one place to another and then stay at that place for a while. These places can be, for example, commercial properties, homes, office centers and so on. As per geo-fencing approach they could be described (defined) as some geographic areas bounded by polygons. It assumes users simply move from fence to fence and stay inside fences for a while. In this article we replace geo-based boundaries with network proximity rules. This new approach let us effectively deploy indoor location based services and provide a significant energy saving for mobile devices comparing with the traditional methods.
Bait and switch advertising
This document discusses bait and switch advertising in the Nepalese context. It defines bait and switch advertising as falsely advertising a product at a low price to attract customers to a store, but then trying to sell them a more expensive product when they arrive. This is an unethical practice that harms both consumers and competitors. The document provides some examples of bait and switch advertising seen in Nepal, such as advertising computers at low prices but then not having them available. It notes that advertising standards are still developing in Nepal's growing advertising industry.

This document discusses wireless technologies for internet of things applications. It describes three common communication models: device to device, device to cloud, and device to gateway. It then focuses on low power wide area network (LPWAN) technologies, explaining that they are suitable for low-cost, battery-powered devices that need to send small packets of data over long distances. Two examples of LPWAN technologies are discussed in depth: LoRaWAN and NB-LTE.
Mobile Networking through Mobile IP
Mobile IP allows devices to change networks while maintaining the same IP address, enabling continuous internet connectivity regardless of location. It works by assigning devices a permanent home IP address and registering a care-of address with a foreign agent when not in the home network, allowing the foreign agent to forward packets to the device's current location. Mobile IP supports security through authentication and aims to optimize routing efficiency.
Context-aware mobile messages
We offer a new model for proactive message delivery to mobile phones. SpotEx application can use any Wi-Fi access point as presence sensor that could activate delivery for some user-generated messages right to mobile phones.
The key idea is how to associate some user-defined messages and Wi-Fi access points. As a result we can build rule-based expert system that describes delivery (or visibility) for user-defined content depending on visibility of Wi-Fi hotspots.

In this paper, we discuss educational courses for Internet of Things and related areas such as Machine to Machine communications and Smart Cities. The Internet of Things models introduce many new business prospects and, of course, they should be presented in the university curriculum. The purpose of the discussed educational program is to examine issues related to information and communication technologies used in Internet of Things projects and related areas based on them, such as Smart Cities. The educational course proposed in this paper aims to introduce students to modern information technology, standing for such areas as Machine to Machine communications, Internet of Things, and Smart Cities.
On Internet of Things programming models
There are two main types of IoT standards: downward-facing standards that establish device connectivity and upward-facing standards that provide common application interfaces. Software standards need a balance between generalization to cover different areas while also making implementation convenient for developers. Popular programming approaches for IoT include mashups using data from multiple sources, microservices architectures, and event-driven dynamic languages like JavaScript. Educational programs should cover topics like sensing, networking, security, data integration, processing and applications.
On Crowd-sensing back-end
This document discusses crowd sensing backends and architectures for mobile crowd sensing applications. It describes common architectures that include local databases on devices with cloud replication, lambda architectures combining batch and stream processing, and support for data streaming technologies. It also covers crowd sensing for video data and various mobile backends and backend-as-a-service providers. Finally, it discusses practical use cases for crowd sensing deployments in Russia.
On Physical Web models
The Physical Web is a generic term describes interconnection of physical objects and web. The Physical Web lets present physical objects in a web. There are different ways to do that and we will discuss them in our paper. Usually, the web presentation for a physical object could be implemented with the help of mobile devices. The basic idea behind the Physical Web is to navigate and control physical objects in the world surrounding mobile devices with the help of web technologies. Of course, there are different ways to identify and enumerate physical objects. In this paper, we describe the existing models as well as related challenges. In our analysis, we will target objects enumeration and navigation as well as data retrieving and programming for the Physical Web

Twitter as a Transport Layer Platform
Internet messengers and social networks have become an integral part of modern digital life. We have in mind not only the interaction between individual users but also a variety of applications that exist in these applications. Typically, applications for social networks use the universal login system and rely on data from social networks. Also, such applications are likely to get more traction when they are inside of the big social network like Facebook. At the same time, less attention is paid to communication capabilities of social networks. In this paper, we target Twitter as a messaging system at the first hand. We describe the way information systems can use Twitter as a transport layer for own services. Our work introduces a programmable service called 411 for Twitter, which supports user-defined and application-specific commands through tweets.
On data model for context–aware services
This paper discusses the issues of data representation for one model of context-aware services. This model is based on network proximity ideas. For network proximity, the location information (latitude, longitude) is replaced with information about proximity to network nodes. Network nodes play a role of tags and let position the users within some restricted area. In this paper, we target wireless networks nodes (Wi-Fi access points, Bluetooth nodes). Services for such models provide to mobile subscribers access to certain information, depending on availability (presence) of wireless networks. And another option is a publication by mobile users context-sensitive information associated with wireless networks. In our paper, we discuss key-value data store deployment as a basic persistence mechanism for network proximity. Also, we provide a description for system-wide cache on the base of Bloom filter.
On time-series databases
Data persistence for time series is an old and in many cases traditional task for databases. In general, the time series is just a sequence of data elements. The typical use case is a set of measurements made over a time interval. Much of the data generated by sensors, in a machine to machine communication, in Internet of Things area could be collected as time series. Time series are used in statistics, mathematical and finance. In this paper, we provide a survey of data persistence solutions for time series data. The paper covers the traditional relational databases, as well as NoSQL-based solutions for time series data.
On Web-based Domain-Specific Language for Internet of Things
This document proposes a domain-specific language (DSL) called LogicIoT for programming Internet of Things (IoT) devices. It discusses challenges in IoT programming related to power constraints, latency, reliability, and data handling. LogicIoT uses a declarative rule-based approach and represents IoT devices as relations that can be queried. It aims to simplify accessing IoT data within web applications using standard web tools while supporting synchronous and asynchronous data updates.
ON THE SYNERGY OF CIRCUITS AND PACKETS
This document discusses the synergy between circuit switching and packet switching technologies in telecommunications networks. It covers: 1) The shift in the telecom market to more packet switching; 2) Trends in switching technologies showing increasing speeds; 3) Advantages of circuit switching for network-on-chip applications; 4) The US Department of Defense transitioning some networks to packet switching while maintaining circuit switching for classified networks; and 5) Lessons for the Russian telecom company Rostelecom regarding their network architecture choices. The conclusion is that circuit switching and packet switching will likely coexist for the foreseeable future, with each having advantages depending on the specific network application and requirements.

From Jules Verne’s Moon landing dream in 1865 to “Star Wars” now
This document discusses the history of space exploration from Jules Verne's 1865 novel depicting a moon landing to modern space missions. It covers early milestones like Yuri Gagarin being the first human in space in 1961 and the Apollo 11 moon landing in 1969. The document also discusses cooperation between the US and Soviet space programs, including the 1975 Apollo-Soyuz mission. The second part discusses communications standards and defense networks, drawing an analogy between the "Tower of Babel" story and challenges of different standards. It references Ronald Reagan's "Star Wars" missile defense program and the goal of a Global Information Grid (GIG) to enable joint military operations.
Sensing
This document discusses open source mobile sensing. It provides an overview of existing open source libraries for mobile sensing and categorizes them. It also examines challenges in mobile sensing, such as battery life and data collection procedures. The goal is to describe current architectures and designs and identify future directions for open source mobile sensing frameworks.
ON SOFTWARE STANDARDS FOR SMART CITIES: API OR DPI
The document discusses standards for software in smart cities. It analyzes the tradeoffs between API and DPI standards approaches. While comprehensive standards may not be implementable and slow innovation, some level of standardization is still needed. The document examines examples like iBeacon and FI-WARE and proposes an ideal framework that uses web technologies like URIs, JSON, and callbacks to access device data through both cloud and direct means. It concludes that all-encompassing standards can conflict with developers, prevailing design trends must be considered, and time-to-market is a key factor for software tools.
On Database for Mobile Phones Ownership
The document discusses a proposed system for digital certificates of mobile phone ownership. The certificates would link a phone's identity (IMEI number) to the owner's social media profile. This allows checking phone ownership through a web search, mobile app, or API. The system has been implemented as an open source project. It aims to provide an additional layer of authentication for mobile devices by verifying the link between the phone and registered owner.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
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.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
