Another simple proof of the non-field-ness of floating point numbers. in this case for the IEEE "double precision" type, that associativity doesn't hold: >>> a, b, c = 2 ** -53, 2 ** -53, 1 >>> (a+

Look at charging rates in watts (watt hours per hour) instead of in percentage; those semis have much larger capacity batteries, so they need a higher charging rate in W to charge 80% in 30 minutes than a vehicle with a smaller battery.

The Debian project has been investigating several alternatives to Alioth's version control functionality. I have not 100% kept up on the discussion, but I think gitlab is either selected for sure or is a leading candidate. https:&#x

Back when I was binge watching a lot of TV shows I would do the same thing -- run them at anywhere from 1.6x to 2.5x (though most often no more than 2x), with close captions on. In fact, I was surprised to hear that the "super-fast&qu

hm, now I wonder what happens if you take 'any old function', add it to a reversed and shifted version of itself, and normalize. do you eventually get one of these self-replicating functions, or are there functions that 'div

Without supporting calculations, I don't believe the numbers very much. Of course Quantum, as a manufacturer of tapes and tape drives, will have chosen assumptions that support using their product lines. At $0.022/GB, the cheapes

"The LLDB debugger APIs are exposed as a C++ object oriented interface in a shared library. The lldb command line tool links to, and uses this public API… The entire API is also then exposed through Python script bindings which allow t

I couldn't tell whether the author was making a good point, because their facts were badly askew. Historically, there were multiple UNIX debuggers. It's true, gdb largely exterminated them (and anyway, when people say UNIX they o

IBM full-size Thinkpads could be configured with a second battery or a second 2.5" hard drive in the spot we think of as where the optical drive goes -- user-interchangeable, even. There have been superportables all along without built

No, I can honestly say I've never worked on a software project that dealt directly with currency values. Personally, in the kinds of projects I do, explicit support for units of measurement would be more beneficial: you'd like to

Yes, I tried to be careful in what I stated, but here's what I meant: "$" is the everyday currency symbol of far fewer people than "¥". "USD" is the everyday currency of only about as many people as &quot

Sarcastically cute. It appears very parochial (in the sense of "limited or narrow outlook") to think that having a single "currency type" is useful, or that using a "$" to denote it is appropriate. While &quo

You can see that just above the endless loop, the code will "enable NMIs". I'm not sure about the nomenclature here (because normally NMI stands for non-maskable interrupts, meaning you can't disable them) but basically

We're talking euclidean distance measure, right? If you are performing many queries against the same set of points {pi}, then yes. Create a structure such as a BSP or quadtree containing all N points {pi} in O(n log n) time, then you

The shortest is the first one, since it extends into the fewest text columns. the last one is the easiest one to maintain, because it can be done on a keyboard with only 15 distinct symbols, while the other variants require 16 and 18. I don

After reading about the case the author knew was not right (negative zero), I wonder why the relevant "equality" test wasn't more like if(isfinite(testValue.f) && isfinite(refValue.f) ? testValue.i
