At the bottom of the page there's a link, "When ‘if’ slows you down, avoid it" [1], that discusses these exact questions. It's basically what @josephg said, but it also shows the assembly language for each version. [1]

A year or so ago I bought a Hisense 65U88KM, which comes with Google TV. During the setup procedure it asked me if I wanted to enable the "smart" features, such as Google TV, the camera and microphone, or connect it to a network.

In Haskell the numerator and denominator of the Rational type are unbounded integers, so one of the (many equivalent) ways of writing it is: ghci> sum [i % (i+1) | i <- [0..9]] 17819 % 2520 ghci> % is the construc

You may discover this if you go to the Apress site, but there is a second edition [1] out. [1] https://hdombrovskaya.wordpress.com/2024/01/11/the-optimizat...

FWIW, in an upcoming version of Java you'll likely be able to do this: $ cat Hello.java void main() { System.out.println("Hello, world!"); } $ java --enable-preview --source 21 Hello.java 2>/dev/nul

The January 16, 2024 edition of the CBC radio show "As It Happens" has an interview with Gerry Vogrincic, the doctor who bought the book in 2007 and just sold it. There's a transcript of the interview here [1]. Search for &q

Somewhat tangentially, that quote seems likely to be from a financial advisor named Gary Shilling [1], rather than Keynes. [1] https://quoteinvestigator.com/2011/08/09/remain-solvent/

I write and review medical software. When I'm reviewing code the most important question is, "Is it correct?" If it's not, then the review simply isn't approved (obviously). Anything that makes it harder to determ

The Communications of the ACM article "The Silent (R)evolution of SAT" [1] gives an overview of some of the techniques used in SAT solvers. I believe it was posted on HN fairly recently. [1] https://cacm.acm.org/m

There is also the recently announced Pentax K-3 III Monochrome [1], but it's a DSLR not a rangefinder. At $2200 I don't know if you'd consider it a "poor man's" camera, but it's certainly cheaper than the

I don't believe that Java currently uses it by default, although I've seen discussion about possibly using it in the future. However, you might find these links useful: - I built an ultra high performance HTTP server in Java

Regarding user-defined types, probably what you're looking for is JEP 401: Primitive Classes (Preview) [1]. I believe it's currently being worked on. [1] https://openjdk.org/jeps/401

That quote comes from here [1]. A few lines later, writing about a talk he had given at a software company, he says: I gave a beautiful lecture, which fell flat on its face. The managers were horrified at the suggestion that flaw

The city recently added sidewalks to my (low traffic) street after doing some sewer upgrades. Lots of people continue to walk on the street because it's consistently flat, as opposed to the dip and slope you encounter on the sidewalk

Java and the JVM from Sun/Oracle. People may not like the language (or the company), but it's good, well-engineered software.

I don't follow it particularly closely, but I recall that there was a recent LWN article, "Security requirements for new kernel features" [1], which discussed the issue. [1] https://lwn.net/Articles/90246

I often use cat because when constructing a pipeline I'll do multiple rounds of: head filename | ... Once its working I find it easy to just type C-aM-dcat (i.e. beginning-of-line kill-word cat).

ISO 8601 specifies durations [1]. For example, Java's Duration type [2] is based upon it. Depending on your language, and how much type safety you want, you could use something Haskell's units library [3]. I believe F# also has u
