How to write rust instead of c and get away with itFlavien Raynaud
Ever tried optimizing a slow Python application and thought: “Oh! I wish I could just write this bit it in Rust”? Well, turns out you can! Let’s discuss why Rust is a better choice than C, how to use Rust to make your apps lightning fast and how to get away with it; without your users even noticing.
As Infrastructure Engineers at Yelp, the challenge we face everyday is: scale. Yelp is mostly a Python shop, so our work often revolves around making Python applications run faster. Until now, we have been using different techniques: faster interpreters, or, more often, C code.
Given its safety guarantees, performance and promise of better tooling than C, we decided we had to give Rust a try. The initial results helped reinforce that there was a lot of opportunity for Rust to play an important role in our production code.
Yelp heavily relies on the Apache Avro serialization format for its internal infrastructure. During the talk, we will show how we implemented avro-rs, an Avro serialization/deserialization library in Rust, how we were able to call it from Python (and in theory from any other language) with very little code, using tools such as cbindgen, CFFI and Milksnake.
This talk would outline how easy it is to write interoperable code in a performant language like Rust and why a company should invest in Rust, over the many other available alternatives, to run production services.
Cluj Big Data Meetup - Big Data in PracticeSteffen Wenz
At the Cluj Big Data Meetup, we shared some insights into TrustYou's big data tech stack. Also we introduced two tools which we've found useful in our production jobs: Apache Pig and Luigi.
Also check out the code samples on GitHub: https://github.com/trustyou/meetups/tree/master/big-data
Powered by Python - PyCon Germany 2016Steffen Wenz
The document discusses how TrustYou uses Python and machine learning techniques like word embeddings and document classification to analyze over 100 million hotel reviews and provide summarizations to travelers. It also provides an overview of TrustYou's architecture, which uses Hadoop and Spark to process large amounts of review data and power their analytics using Python libraries for natural language processing and machine learning. The company is hiring data engineers and web developers to continue expanding their platform.
Slides for the Cluj.py meetup where we explored the inner workings of CPython, the reference implementation of Python. Includes examples of writing a C extension to Python, and introduces Cython - ultimately the sanest way of writing C extensions.
Also check out the code samples on GitHub: https://github.com/trustyou/meetups/tree/master/python-c
The document discusses debugging tools and techniques, focusing on GDB (the GNU Project debugger). It covers:
1. How debuggers work under the hood using ptrace to control programs and set breakpoints.
2. The basics of using GDB - starting and running programs, setting breakpoints, printing variables, and examining stack traces.
3. Additional GDB commands for inspection, as well as examples of inline assembly code, calling conventions, and disassembling code.
This document provides an architect's view of Hadoop I/O based on analysis using vProbes instrumentation. It summarizes the results of a controlled small-scale study on a single-node Hadoop cluster running TeraSort. The study found that mapper tasks generate multiple temporary spill files and the reducer performs a large volume of shuffle I/O. It also presents initial observations about the Hadoop I/O model, including that mapper spill files account for 75% of disk bandwidth and HDFS input/output accounts for 12% of total bandwidth.
This document contains AutoLISP functions for analyzing and extracting data from 2D and 3D objects in AutoCAD. It includes functions to calculate distances between 2D points, extract coordinate data and write it to a file, analyze spline curves on polylines and write curve data like radii, angles and lengths to a file. The functions prompt the user for input like selecting objects or points and allow controlling snapping options.
This document summarizes a class lecture on imperative programming. It discusses list appending vs mutable list appending and how the latter does not create new cons cells. It then compares the performance of list appending vs built-in append for immutable lists. Mutable list reversing is discussed, with an exercise to implement mlist-reverse! efficiently without extra consing. Students are reminded that problem set 5 is due Friday unless they provide feedback on exercises or the online course book, in which case it can be turned in on Monday.

[JS EXPERIENCE 2018] Javascript Event Loop além do setInterval - Derek StavisiMasters
The document discusses the JavaScript event loop model. It explains that JavaScript is single-threaded but asynchronous and non-blocking. It uses a call stack, task queue, and event loop to handle concurrency. Functions are added to the call stack and run synchronously until complete, after which they are removed from the stack. Asynchronous functions like timeouts and intervals add callbacks to the task queue to be run asynchronously by the event loop. The event loop continually checks the call stack and task queue, running any queued callbacks after the stack is empty. This allows for asynchronous and concurrent behavior despite single-threading.
The document contains code snippets for various sorting and searching algorithms including bubble sort, insertion sort, selection sort, and linear search. It also includes code to find the sum and largest value of arrays, determine angle type, and solve quadratic equations.
This document contains programs to simulate various CPU scheduling algorithms and memory management techniques. It includes programs for FCFS, SJF, priority, and round robin scheduling. It also includes programs to simulate MVT and MFT memory allocation algorithms, as well as FIFO and LRU page replacement algorithms. The programs take input data, perform the necessary calculations, and output scheduling or memory allocation results.
Many people ask about how to develop a functional mindset. It’s difficult if you’ve learned another paradigm and don’t know where to start. Functional thinking is a set of habits that you can train that will serve you well while programming in any language.
Performing quantitative software analytics studies can be an immensely rewarding activity for scientists performing empirical research. However, such studies often pose numerous engineering challenges. The researcher must hunt down appropriate data sets, devise bespoke collection and processing tools, and optimise performance to match the size of the collected data. I will discuss principles and strategies that can be used to deal with these problems, and present examples of associated tools and techniques. Some particularly effective strategies associated with data set construction involve recursion, web searching, synthesis, probing, instrumentation, and the nurturing of alliances. On the processing front approaches include the opportunistic scavenging of tool front-ends, the exploratory development of pipelines, as well as the exploitation of tool interoperability, scripting languages, and their rich libraries. The required performance can be obtained through parallelism, stream processing, the judicious use of low-level facilities, and the choice of appropriate samples. I will finish the presentation with an overview of open problems and challenges in software analytics in vertical domains, data analysis, and under-represented stakeholders.
This document discusses using the C to Go translation tool c2go to translate C code implementing quicksort algorithms into Go code. It provides examples of translating simple quicksort C code, improving the translation by using a configuration file, and how c2go handles standard C functions like qsort by translating them to their Go equivalents. The examples demonstrate how c2go can generate valid Go code from C code but may require some manual fixes or configuration to handle certain data structures or language differences.

The document discusses two C programming examples that use structures. The first example stores the name and price of 3 books in arrays and prints the input. The second example defines a book structure with name and price fields, declares 3 structure variables, takes input for each book, and prints the stored name and price for each book. Both examples demonstrate using structures to organize related data in C programming.
The document describes four different CPU scheduling algorithms: First Come First Serve (FCFS), Shortest Job First (preemptive and non-preemptive), Priority scheduling (non-preemptive), and Round Robin. For each algorithm, pseudocode is provided to simulate the scheduling of processes and calculate metrics like waiting time and turnaround time. The FCFS algorithm calculates these metrics in a straightforward manner based on arrival time and burst time of each process. Shortest Job First simulates sorting processes by burst time and calculating wait times and turnaround times accordingly. Priority scheduling first sorts by priority then calculates metrics. Round Robin simulates time slicing by allocating a time quantum to each process in turn.
