A prvalue is not a temporary
This is part one of a series of blog posts on temporaries, copies, return value optimization, and passing by value vs. reference. A good place to start, and the point of this first article, is how a prvalue isn’t necessarily a temporary. If you’re entirely new to value categories (lvalues, rvalues etc.), you might want […]

Scientists find ways to boost memory in aging brains
Reactivating a gene that supports memory A second study, published in the Brain Research Bulletin and led by Jarome with doctoral student Shannon Kincaid, focused on IGF2, a growth-factor gene that supports memory formation. As the brain ages, IGF2 activity drops as the gene becomes chemically silenced in the hippocampus. “IGF2 is one of a small number […]
Man who threw sandwich at US border agent not guilty of assault
A Washington DC protester has been found not guilty of misdemeanor assault after a video emerged showing him hurling a sandwich at a US border patrol agent.

When did people favor composition over inheritance?
The phrase “favor composition over inheritance” has become one of those thought-terminating cliches in software design, and I always like to take a deeper look at those to understand where they come from and what ideas we’re missing if we just take the phrase at face value without engaging with the discussion that led to […]
Writing software is an act of learning. Don’t automate it.
Software development has always resisted the idea that it can be turned into an assembly line. Even as our tools become smarter, faster, and more capable, the essential act remains the same: we learn by doing. An Assembly Line is a poor metaphor for software development In most mature engineering disciplines, the process is clear: […]

Universe’s expansion ’is now slowing, not speeding up’
The universe’s expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. ”Remarkable” findings published today in Monthly Notices of the Royal Astronomical Society cast doubt on the long-standing theory that a mysterious force known as ’dark energy’ is driving distant galaxies away increasingly faster. Instead, […]
