One of the great things about Python is the way you can easily juggle items around in collections -- lists, dictionaries, sets -- and the shortcuts you get when you combine them. For example, to get a unique collection of elements in a list: list(set(my_list)) will do it. Similar things happen in Smalltalk but these … Continue reading Smalltalk collections for Python coders

[ This is an article that I started writing a few years back, when I was experimenting with Puppy Linux, then put on hold. Much of it is still useful, so the post merits to go public. ] Having written a walk-through on how to set up a Linux system ready for compiling software (see here), … Continue reading Setting up QuantLib in Linux

The principle of pricing in the risk-neutral measure is the foundation of quantitative analysis. I have already written a post which gives an intuitive description of the concept of a risk premium and which discusses some aspects of the risk-neutral approach (see here). In this post I want to look again at risk-neutral pricing. It … Continue reading 客户管理 - 绿色软件联盟:2021-11-12 · 知奇会员档案管理是一款用户、会员、客户相关信息记录、提取、查询的软件。通用任何会员管理。使用Sqlite本地数据库。它可以帮您记录每个客户的全面资料，需要时方便调取。

If you have an idea then you have to represent it as a test and the other person can follow your idea more easily. Should you always write a test first? I think … Continue reading TDD and your solution domain

This is a good example here of a bad explanation of FP: basically saying that FP is intelligent whilst non-FP is dumb. I recently read a couple of blog posts by Kris Jenkins which give his answers to the questions: What is functional programming? Which languages could be said to be functional programming languages? I … Continue reading What is Functional Programming and what does it do for you?

A few years ago I came up with a useful improvement to the Jarrow-Yilidirm inflation model: let's diffuse the inflation curve rather than the real-yield curve. It turns out that this gives the modern inflation derivatives trader a much better risk management tool. In the attached paper I give the details. I wrote it up … Continue reading Improving the Jarrow-Yildirim inflation model
The value of open source
Of the many points made by Tom Preston-Warner in his article Open source (almost) everything, I particularly like the paragraph on why you should let your coders work on open source projects: ... dedication to open source code is an amazingly effective way to retain ... talent. Let’s face it, great developers can take their … Continue reading 木瓜云梯子
诗歌发展史_图文_百度文库:你将木瓜投赠我，我拿琼琚作回报。 不是为了答谢你，珍重情意永相好。 你将木桃投赠我，我拿琼瑶作回报 ... 脚著谢公屐，身登青云梯。 半壁见海日，空中闻天鸡。千岩万转路不定，迷花倚石忽已暝。 熊咆龙吟殷岩泉，栗深林兮惊层巅。云青青兮欲 ...
I use Underscore an awful lot. I have many good things to say about Underscore in the context of Functional Programming, but this post explains a simple one-liner which got my Underscore code quickly into our ever-increasing collection of TypeScript modules. This is not a long term, fully robust solution incorporated into our Grunt build … Continue reading TypeScript with Underscore, a simple Grunt way
