DHAT is primarily a tool for examining how programs use their heap allocations.

It tracks the allocated blocks, and inspects every memory access to find which block, if any, it is to. It presents, on a program point basis, information about these blocks such as sizes, lifetimes, numbers of reads and writes, and read and write patterns.

In this paper, we tackle the problem of tiling a domain with a set of deformable templates. A valid solution to this problem completely covers the domain with templates such that the templates do not overlap. We generalize existing specialized solutions and formulate a general layout problem by modeling important constraints and admissible template deformations. Our main idea for the solution is to break the layout algorithm into two steps: a discrete step to lay out the approximate ...

The popular consciousness has accepted many dietary villains over the course of the last half century, ranging from fat, to protein, to salt, to carbohydrates. More often than not, dietary constituents that have fallen under such scrutiny have been exonerated in time, as more and more scientific data is brought to light. I suspect that there is a growing number of people who are now wrongfully demonizing vegetable oils as well. Both skepticism and generally negative attitudes toward ...

A detailed essay on the process of building a post-processing stylized shader reproducing the style of legendary artist Jean Giraud a.k.a Moebius for your React Three Fiber projects. In it, I detail the process of drawing outlines with a Sobel Filter as well as custom shadow and lighting patterns to bring a unique style to your WebGL scene.

Prefer SVG over PNG, trust browsers to downscale, drop obscure formats—the ultimate, exhaustive guide to favicons for modern web. Includes steps for static HTML and Webpack.

Dropflow is a CSS layout engine created to explore the reaches of the foundational CSS standards (that is: inlines, blocks, floats, positioning and eventually tables, but not flexbox or grid). It has a high quality text layout implementation and is capable of displaying many of the languages of the world. You can use it to generate PDFs or images on the backend with Node and node-canvas or render rich, wrapped text to a canvas in the browser.

Restoring tree cover changes albedo, which is the fraction of sunlight reflected from the Earth’s surface. In most locations, these changes in albedo offset or even negate the carbon removal benefits with the latter leading to global warming. Previous efforts to quantify the global climate mitigation benefit of restoring tree cover have not accounted robustly for albedo given a lack of spatially explicit data. Here we produce maps that show that carbon-only estimates may be up to 81%...

Web browsers are ubiquitous, but how do they work? This book explains, building a basic but complete web browser, from networking to JavaScript, in a couple thousand lines of Python.

Forget death and taxes. The only certainty on the web is change. Ste Grainer takes a brief look at the history of the web and how it has been constantly reinvented. Then he explores where we are now, and how we can shape the future of the web for the better.

Lezer (the Dutch word for reader, pronounced like “laser”) provides a parser generator that outputs JavaScript modules, which can be loaded to parse code into a non-abstract syntax tree. This tree can then be used to do highlighting and basic semantic analysis.

Computer science often emphasizes processing efficiency, leaving robustness to be addressed separately. However, robustness requires redundancy, which efficiency eliminates. For safer and more scalable computing, we must embrace and manage this tradeoff.

When highly trained professionals now babysit machines, they lose their skills. Retaining skills requires practice. How do we ensure that those skills are not lost? If we expect humans to be able to take over from machines during crucial moments, those humans must retain strong skills. Loss of knowledge has serious consequences locally and systemically.

But what we needed was a 10,000-port switch that cost $100/port. So, almost exactly 20 years ago, we sent this five-page RFP to four different switch vendors (IIRC: Cisco, Force10, HP, and Quanta) and tried to interest them in building such a switch. They politely declined because “nobody is asking for such a product except for you”, and they anticipated margins to be low.

If you've got a sharp eye and a knack for details, you might have noticed the sun coming from an unrealistic angle in most shaded relief maps: the north. In this article we explain why.

As the world’s largest volume manufacturer, Volkswagen has been an early adopter when it comes to e-mobility. This gives the Group all the opportunities and prerequisites to be among the winners in the current technological transition. However, politicians, industry and the general public still discuss from time to time whether hydrogen cars would not bring “even more” advantages. And whether the fuel cell is more efficient. We clear things up.
