gRPC - RPC rebirth?
Presentation at NetPonto community: "We’re going to discuss gRPC, Google’s open-source RPC framework. I’ll dive a bit into the history of RPC as a protocol, and what its historical use has been. I’ll also highlight some benefits to adopt gRPC and how its possible to swap out parts of gRPC and still take advantage of gRPC’s benefits. Finally I’ll answer the question that has been on many lips since gRPC was announced — what does this mean for REST?"
Jonathan Coveney: Why Pig?
Pig is a useful tool for exploring data sets and describing data flows easily through scripts. However, it has some weaknesses like inconsistent syntax, lack of testing support, and an aging code base. While Pig works well for many companies, its suitability may decline as companies' data needs grow more complex with distributed teams of data scientists and engineers. For Pig to remain useful, it will need improvements in areas like types, performance, UDF support, and testing to better support "big data" teams in the future.
gRPC Design and Implementation
The document discusses gRPC, an open-source framework for building distributed applications and services. It was motivated by Google's experience with internal RPC systems handling over 1010 RPCs per second. gRPC uses HTTP/2 for transport, allowing it to take advantage of existing network infrastructure while enabling features like bidirectional streaming. It generates client and server code from IDL definitions, supporting multiple languages.

The document discusses gRPC, an open source framework for building microservices. It was created by Google to be a high performance, open source universal RPC framework. gRPC uses HTTP/2 for transport, Protocol Buffers as the interface definition language, and generated client/server code for many languages to make cross-platform communications simple and efficient. The document provides an overview of gRPC's goals and architecture, how to define a service using .proto files, and examples of common RPC patterns like unary, streaming, and bidirectional calls.

Design and Implementation of the Security Graph Language
Today software is built in fundamentally different
ways from how it was a decade ago. It is increasingly common
for applications to be assembled out of open-source components,
resulting in the use of large amounts of third-party code. This
third-party code is a means for vulnerabilities to make their
way downstream into applications. Recent vulnerabilities such
as Heartbleed, FREAK SSL/TLS, GHOST, and the Equifax data
breach (due to a flaw in Apache Struts) were ultimately caused
by third-party components. We argue that an automated way to
audit the open-source ecosystem, catalog existing vulnerabilities,
and discover new flaws is essential to using open-source safely.
To this end, we describe the Security Graph Language (SGL), a
domain-specific language for analysing graph-structured datasets
of open-source code and cataloguing vulnerabilities. SGL allows
users to express complex queries on relations between libraries
and vulnerabilities in the style of a program analysis language.
SGL queries double as an executable representation for vulnerabilities, allowing vulnerabilities to be automatically checked
against a database and deduplicated using a canonical representation. We outline a novel optimisation for SGL queries based on
regular path query containment, improving query performance up to 3 orders of magnitude. We also demonstrate the
effectiveness of SGL in practice to find zero-day vulnerabilities

Per aspera ad grid To the grid computing through difficulties
The document discusses the history and evolution of grid computing from the perspective of the author. It covers early work using clusters for computationally intensive tasks in the late 1990s, the development of grid middleware like Globus to schedule tasks on heterogeneous resources, and issues with standardization and interoperability between different grid projects. It then outlines the shift towards more modular, service-oriented architectures exemplified by the ARC middleware, as well as changes brought by volunteer desktop grids, MapReduce, and the rise of cloud computing where resources are virtualized and provided as a service.

"Building, deploying and running production code at Dropbox" Васильев Леонид,...
The document discusses Dropbox's approach to building, deploying, and running production code. For building, they migrated to Bazel for its reproducibility, hermetic builds, and ability to track dependencies across languages. For deploying, they use YAPS to package dependencies and services into read-only squashfs images. For running services, they use Dbxinit for process management and enforce resource limits, while also integrating containers via RunC. Overall their goal is robust and automated systems from building to deployment to operations.
XHR Web APps F2F at San Jose
The document discusses the status and plans for XMLHttpRequest. It notes that the specification reached TR publication in December 2012. There are test submissions from Microsoft, Ms2ger, and Opera. The WHATWG has made 14 commits to the spec. There are 13 open bugs. The plan is to finalize a baseline version as REC by 2013 focusing on implemented features, and a "bleeding edge" version addressing controversial issues with a goal of REC by 2014. Major issues include the behavior of overrideMimeType, HTTP authentication, and streaming responses.
HTTP2 and gRPC
gRPC is a modern open source RPC framework that enables client and server applications to communicate transparently. It is based on HTTP/2 for its transport mechanism and Protocol Buffers as its interface definition language. Some benefits of gRPC include being fast due to its use of HTTP/2, supporting multiple programming languages, and enabling server push capabilities. However, it also has some downsides such as potential issues with load balancing of persistent connections and requiring external services for service discovery.
Open Chemistry, JupyterLab and data: Reproducible quantum chemistry
The Open Chemistry project is developing an ambitious platform to facilitate reproducible quantum chemistry workflows by integrating the best of breed open source projects currently available in a cohesive platform with extensions specific to the needs of quantum chemistry. The core of the project is a Python-based data server capable of storing metadata, executing quantum chemistry calculations, and processing the output. The platform exposes RESTful endpoints using programming language agnostic web endpoints, and uses Linux container technology to package quantum codes that are often difficult to build.
The Jupyter project has been leveraged as a web-based frontend offering reproducibility as a core principle. This has been coupled with the data server to initiate quantum chemistry calculations, cache results, make them searchable, and even visualize the results within a modern browser environment. The Avogadro libraries have been reused for visualization workflows, coupled with Open Babel for file translation, and examples of the use of NWChem and Psi4 will be demonstrated.
The core of the platform is developed upon JSON data standards, and encouraging the wider adoption of JSON/HDF5 as the principle storage mediums. A single page web application using React at its core will be shown for sharing simple views of data output, and linking to the Jupyter notebooks that documents how they were made. Command line tools and links to the Avogadro graphical interface will be shown demonstrating capabilities from web through to desktop.
OSMC 2019 | Grafana Loki: Like Prometheus, but for Logs by Ganesh Vernekar
Loki is a horizontally-scalable, highly-available log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate, as it does not index the contents of the logs, but rather labels for each log stream. Loki initially targets Kubernetes logging, using Prometheus service discovery to gather labels and metadata about log streams. By using the same index and labels as Prometheus, Loki enables you to easily switch between metrics and logs, enhancing observability and streamlining the incident response process – a workflow we have built into the latest version of Grafana. In this talk we will discuss the motivation behind Loki, its design and architecture, and what the future holds. Its early days, but so far the response to the project has been overwhelming, with more the 6.5k GitHub stars and over 12hrs at the top spot on Hacker News. Loki is an opensource project, Apache licensed.
1548 PROJECT DEMO
The document summarizes a student's final project presentation which had two parts:
1) A latency study of different network topologies that found no direct relationship between latency and topology. Further analysis is needed.
2) A demonstration of dynamically deploying a second controller to reduce the workload of the original controller once the number of hosts exceeded a threshold of 3. The new controller was given a copy of the network topology view.
Luigi Presentation at OSCON 2013

Python 2 is dead! Drag your old code into the modern age
The clock is ticking on Python 2.7, with support to be dropped in January 2020. With major dependencies such as Django, NumPy and pandas moving to Python 3 only, the time has come for even big established codebases to consider upgrading. Many organisations are still postponing for various reasons; we will attempt to demonstrate that with a bit of planning and perseverance, and the assistance of some handy tools, we can embrace the future!
This session will provide a first-hand perspective on how we upgraded a large (~65,000 lines of python code) 8-year-old Django project with multiple external dependencies from Python 2.7 to Python 3.6.
We will briefly discuss the benefits of upgrading to Python 3, and architectural considerations. The session will primarily focus on the practicalities of upgrading the code itself. We will not try to provide a single “best” solution for upgrading to Python 3, but rather will introduce some of the available tools, provide an insight into how we used them, and their advantages and disadvantages from our experience. We will discuss preparatory steps and approaches, strategies for dealing with external dependencies, and “gotchas” that we encountered during the process.
The aim of this session is to provide an example of how a Python 3 upgrade on an established commercial product can be successfully completed, and to furnish audience members with a set of tools and strategies to help them with their own projects.
Enjoy Type Hints and its benefits
The document discusses a presentation on the benefits of type hints in Python. It provides an outline of the presentation which includes an introduction to type hints, how to use type hints, and the benefits of type hints. Some key benefits mentioned are improved code completion, the ability to catch type errors without running code, and using type hint tools for static type analysis.

[GSoC 2017] gopy: Updating gopy to support Python3 and PyPy
gopy is an excellent tool which generates (and compiles) a CPython extension module from a go package. And I hope more developers could make full use of gopy to migrate their go code into python code. To make gopy more advanced, It is necessary to provide APIs for various Python compiler versions, such as CPython 2/3 and PyPy. This can be improved with CFFI or ctypes. Moreover, many go’s implementations/features are not yet implemented in gopy. So we need to implement implementations such as slices, interfaces, and maps in the go.
My goal is to update gopy by using CFFI to support Python3 and PyPy and write detailed documents

The Onward Journey: Porting Twisted to Python 3
This document discusses porting the Twisted Python library to Python 3. It describes Twisted as a networking library that uses asynchronous programming. The author ported over 325 pull requests to help move Twisted to Python 3. Some challenges included changes to Python 3 like print becoming a function and str handling, as well as porting old C extensions. Running extensive unit tests was important. While difficult, porting benefits code quality and keeps Twisted compatible with Python's direction.

Programming with Python - Basic
s[:] makes a copy.
– s[:]
– slice(0, 3)
– s[slice(0, 3)]
– s[0:3]
– s[:3]
– s[3:]
– s[:-3]
So slice is more flexible.
– s[start:stop:step]
– s[::-1] # reverse
– help(slice)
– s = 'Hello World'
– s[5:11:2]
– 'oWl'
– s[::2]
– 'Hlo rd'
– s[-

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.
