Solving LinkedIn Queens with APL

Solving LinkedIn Queens with APL 14 Jun 2025 on Peter Vernigorov’s blog A couple months ago I noticed that LinkedIn now has a few simple games. They’re not much to write home about, but I really enjoy playing Queens. This week I saw two posts about solving the Queens game programmatically. Both were quite interesting to me, so I thought this was a good opportunity to also solve the game in my favourite language - APL - and share my experience.

techcrunch.com Ivan Mehta 2025-09-21 12:00:00

Simplest C++ Callback, from SumatraPDF

news.ycombinator.com Unknown 2025-09-21 05:26:38

SumatraPDF is a Windows GUI application for viewing PDF, ePub and comic books written in C++. A common need in GUI programs is a callback. E.g. when a button is clicked we need to call a function with some data identifying which button was clicked. Callback is therefore a combo of function and data and we need to call the function with data as an argument. In programming language lingo, code + data combo is called a closure. C++ has std::function<> and lambdas (i.e. closures). Lambdas convert

In Brief Chinese companies Huawei and SMIC may have a difficult time accessing resources needed to build AI chips, due to Taiwanese export controls. Bloomberg reports that Taiwan’s International Trade Administration placed the two companies and their subsidiaries on an updated list of entities designated as strategic high-tech commodities.

Biofuels Policy, a Mainstay of American Agriculture, a Failure for the Climate

The American Midwest is home to some of the richest, most productive farmland in the world, enabling its transformation into a vast corn- and soy-producing machine—a conversion spurred largely by decades-long policies that support the production of biofuels. But a new report takes a big swing at the ethanol orthodoxy of American agriculture, criticizing the industry for causing economic and social imbalances across rural communities and saying that the expansion of biofuels will increase greenh

SIMD-friendly algorithms for substring searching (2016)

Introduction Popular programming languages provide methods or functions which locate a substring in a given string. In C it is the function strstr , the C++ class std::string has the method find , Python's string has methods pos and index , and so on, so forth. All these APIs were designed for one-shot searches. During past decades several algorithms to solve this problem were designed, an excellent page by Christian Charras and Thierry Lecroq lists most of them (if not all). Basically these al
