- AWS Lambda 简化功能实现
- aws lambda

A Step by Step Guide with Code Snippets for Packing Your Python 2.7 Function for AWS Lambda.

(`是也乎:`

从 Lambda 发布以来 AWS 就一直在折腾有关教程 但是, 和 Heroku 的海量友好文章相比, 内部工程师写的就一直非常嗯哼了...

- 如何对机器学习代码进行单元测试
- testing, machine learning

Over the past year, I’ve spent most of my working time doing deep learning research and internships. And a lot of that year was making very big mistakes that helped me learn a lot about not just about ML, but about how to engineer these systems correctly and soundly. One of the main principles I learned during my time at Google Brain was that unit tests can make or break your algorithm and can save you weeks of debugging and training time.

(`是也乎:`

对 AI 的单元测试也必须是 AI 了?

- Zulip 1.7: Python 构造的开源团队聊天工具
- new release

Zulip is the world’s most productive team chat software, an alternative to Slack, HipChat, and IRC. Zulip combines the immediacy of chat with the asynchronous efficiency of email, and is 100% free and open source software.

- 学习树数据结构
- tree, data structure

This post is an attempt to we better understand the Tree Data Structure and clarify any doubts about it. We will learn about what is a tree, examples of it, its terminology, how it works, and a technical implementation (a.k.a code!)

- 跟踪你的数据新闻
- journalism

Do you really know how you ended up with those results after analyzing the data from Public Source?

(`是也乎:`

虽然都是对公开数据的分析结果 但是,你真的保证人家分析过程中没有嗯哼? )

- 超越 Python 惯用法
- idiomatic

Note - If you have read Writing Idiomatic Python - By Jeff Knupp. You might want to read what Oleksandr has to say in this post. Personally I learned a lot from the book and recommend it regularly to everyone. People don’t speak entirely in idioms unless they are totally off their rockers. Overusing idioms makes you seem more than self-confident, full of air, and frankly not playing with a full deck. It is fair to middling to spice your language with idioms a little bit, but build the whole speech entirely out of them is beside the point.

因为上一个版本时间太久了, 所以, 作者认为应该升级了...一切为了 Py3

- TensorFlow 101
- tensorflow

TensorFlow is an open source machine learning library developed at Google. TensorFlow uses data flow graphs for numerical computations. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. In this post we will learn very basics of TensorFlow and we will build a Logistic Regression model using TensorFlow.

(`是也乎:`

所以, PyTorch 在爆发...

- SciPy 发布 1.0.0
- new release

We are extremely pleased to announce the release of SciPy 1.0, 16 years after version 0.1 saw the light of day. It has been a long, productive journey to get here, and we anticipate many more exciting new features and releases in the future.

(`是也乎:`

用了16年, 才升级到 v1.0,对比隔壁3年飙到 v56 的大家... )

- Bayesian-Modelling-in-Python:
- Bayesian

Welcome to "Bayesian Modelling in Python" - a tutorial for those interested in learning how to apply bayesian modelling techniques in python (PYMC3). This tutorial doesn't aim to be a bayesian statistics tutorial - but rather a programming cookbook for those who understand the fundamental of bayesian statistics and want to learn how to build bayesian models using python. The tutorial sections and topics can be seen below.

In my talk at Clojure Conj I mentioned how a project from Oracle Labs named GraalVM might have to potential for Clojure to interop with Python on the same VM. At the time of the talk, I had just learned about it so I didn’t have time to take a look at it. Over the last week, I’ve managed to take it for a test drive and I wanted to share what I found.

(`是也乎:`

所以? Clojure 在拼命包容其它语言来给自己续命? )

- Sublime Text 用户应该用的 7 高能快捷键
- sublime, offtopic

Through my career as a software developer, I have appreciated one text editor the most, Sublime Text. I began with writing code in Notepad++ long long time ago, then tried IDEs as well but nothing came as close to working smoothly as Sublime Text. This blog is also written using Sublime Text.

Why are we offering cloud Jupyter notebooks? If you use Jupyter or IPython notebooks for your business or for working on assignments or research work, you are probably familiar with the challenges that come with setting up a stable Jupyter system on a machine.

I was once a huge fan of FSMs (Finite State Machines) as a mechanism to keep track of states. Automata theory is the basis of class of computational problems solvable by discrete math. I had used fysom in the past but this time I wanted something home grown. I was able to write complex language parse in a couple hours using only 200 lines of code.
