Although software developers are usually reluctant to use static analysis to detect issues in their source code, our automatic just-in-time static analysis assistant was integrated into an Integrated Development Environment, and was evaluated positively by its users. We conducted interviews to understand the impact of the tool on experienced developers, and how it performs in comparison with other static analyzers. We learned that the availability of our tool as a default IDE feature and its automatic execution are the main reasons for its adoption. Moreover, the fact that immediate feedback is provided directly in the related development context is essential to keeping developers satisfied, although in certain cases feedback delivered later was deemed more useful. We also discovered that static analyzers can play an educational role, especially in combination with domain- specific rules.

Pharo Quality Engine: The Last Strokes (esug2017)

Yuriy Tymchuk

Pharo 6 was shipped with Renraku — the single quality model to rule them all. While being an advanced piece of software, Renraku alone provided no immediate benefits to end users. In this talk, we are going to present the upcoming development changes that utilize Renraku and range from advanced bug fixing guidance to the five times speed up in quality rules; as well as a few more usability features.

The False False Positives of Static Analysis (sattose2017)

Yuriy Tymchuk

Static analysis tools may produce false positive results, which negatively impact the overall usability of these tools. However, even a correct static analysis report is sometimes classified as a false positive if a developer does not understand it or does not agree with it. Lately developers' classification of false positives is treated on a par with the actual static analysis performance which may distort the knowledge about the real state of static analysis. In this paper we discuss various use cases where a false positive report is not false and the issue is caused by another aspects of static analysis. We provide an in-depth explanation of the issue for each use case followed by recommendations on how to solve it, and thus exemplify the importance of careful false positive classification.

Walls, Pillars and Beams: A 3D Decomposition of Quality Anomalies (vissoft2016)

Yuriy Tymchuk

Quality rules are used to capture important implementation and design decisions embedded in a software system’s architecture. They can automatically analyze software and assign quality grades to its components. To provide a meaningful evaluation of quality, rules have to stay up-to-date with the continuously evolving system that they describe. However one would encounter unexpected anomalies during a historical overview because the notion of quality is always changing, while the qualitative evolution analysis requires it to remain constant. To understand the anomalies in a quality history of a real-world software system we use an immersive visualization that lays out the quality fluctuations in three dimensions based on two co-evolving properties: quality rules and source code. This helps us to identify and separate the impact caused by the changes of each property, and allows us to detect significant mistakes that happened during the development process.

When QualityAssistant Meets Pharo [Enforced Code Critiques Motivate More Valu...

Yuriy Tymchuk

Static analysis tools can aid in software quality assessment, but are rarely used by software developers. Poor usage of quality analysis tools not only means missed opportunities for the quality of software systems, but also results in little feedback, which in turn slows the improvements of the quality rules themselves. We introduced a set of intrusive quality plugins and integrated them into the Pharo IDE. This not only triggered a feedback loop that led to improvements of the existing rules, but also encouraged removal of some rules and integration of new ones. Our analysis of changes to the rules suggests that precise rules capturing a domain-specific logic are more valuable than general ones.

Stories About Renraku — the new Quality Model of Pharo (esug2016)

Yuriy Tymchuk

Earlier this year Pharo 5 was released with QualityAssistant on board. However the live quality feedback in the code browser is just the tip of the iceberg. The main value comes from Renraku — a quality model that was forged during the last two years based on the requirements of quality tools. One cannot simply “show” Renraku as it is just a meta-model with a set of handy functions. And I will never allow myself to bore audience by presenting dry specifications. Luckily I have enough stories that accumulated during the development to unveil Renraku by telling about the challenges and solutions that shaped Pharo’s quality model.

Beyond the Concept of Quality in Pharo (esug2015)

Yuriy Tymchuk

People were using the notion of quality for as long as they live, and software engineers are not an exception. Our goal is to introduce a concept of quality as a first class entity that can be used to facilitate the software evolution process. Last year we have presented ViDI - a Visual Design Inspector. Now we want to present QualityAssistant - a tool which assists you with a quality of your code right when you are working with it. QualityAssistant is based on an idea that each code entity should be able to tell about it’s quality, and the ways to improve it.

Code Review: Veni, ViDI, Vici (saner15)

Yuriy Tymchuk

!!! For the demo purposes of ViDI there was a set of videos in the presentation. You can see the full demo video here: http://youtu.be/EtdkcNBJAec Modern software development sees code review as a crucial part of the process, because not only does it facilitate the sharing of knowledge about the system at hand, but it may also lead to the early detection of defects, ultimately improving the quality of the produced software. Although supported by numerous approaches and tools, code review is still in its infancy, and indeed researchers have pointed out a number of shortcomings in the state of the art. We present a critical analysis of the state of the art of code review tools and techniques, extracting a set of desired features that code review tools should possess. We then present our vision and initial implementation of a novel code review approach named Visual Design Inspection (ViDI), illustrated through a set of usage scenarios. ViDI is based on a combination of visualization techniques, design heuristics, and static code analysis techniques.

Launch Your Streaming Platforms in Minutes

Roshan Dwivedi

The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown: Pros of Speedy Streaming Platform Launch Services: No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge. Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker. All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations. Things to Consider: Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions. Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option. Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options). Examples of Services for Launching Streaming Platforms: Muvi [muvi com] Uscreen [usencreen tv] Alternatives to Consider: Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited. Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform. Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

Graspan: A Big Data System for Big Code Analysis

Aftab Hussain

We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs. We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations. These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18. - Accepted in ASPLOS ‘17, Xi’an, China. - Featured in the tutorial, Systemized Program Analyses: A Big Data Perspective on Static Analysis Scalability, ASPLOS ‘17. - Invited for presentation at SoCal PLS ‘16. - Invited for poster presentation at PLDI SRC ‘16.
