Toward an API for the real numbers

The Morning Paper

Towards an API for the real numbers , Boehm, PLDI’20. Last time out we saw that even in scientific computing applications built by experts, problems with floating point numbers are commonplace. The idiosyncrasies of floating point representations also show up in more everyday applications such as calculators and spreadsheets. Here the user-base is less inclined to be sympathetic: If arithmetic computations and results are directly exposed to human users who are not floating point experts, floati

Node.js vs PHP- A Head to toe Comparison of Server-side Technologies

That said, the PHP community has started realizing a lack of relevant and updated projects. Surprisingly, this is exactly where Node.js is most successful- building a strong user base across projects meant for modern-day use cases. .

Spying on the floating point behavior of existing, unmodified scientific applications

The Morning Paper

Spying on the floating point behavior of existing, unmodified scientific applications Dinda et al., HPDC’20. It’s common knowledge that the IEEE standard floating point number representations used in modern computers have their quirks, for example not being able to accurately represent numbers such as 1/3, or 0.1.

Self-documenting Architecture

Strategic Tech

One of the biggest time costs in software development is understanding how a system works. And the problem may be growing. Systems are getting more complex yet our ability to understand them doesn’t seem to be growing at the same rate. As we continuously develop software systems, the complexity slowly increases and we don’t fully realise it. Nobody sets out to create a Big Ball of Mud, but many codebases end up that way due to the cumulative effect of the thousands of small changes we make.
