I don't the fanaticism around memory safe languages. We've had memory safe languages for a very long time. Algol-60, the granddaddy of many modern languages, had it sixty-five years ago. Algol-60 also had other safety features tha

I've still got mine. It's been well used but is hanging together still.

Under uClinux, executables can be position independent or not. They can run from flash or RAM. They can be compressed (if they run in RAM). Shared libraries are supported on some platforms. All in all it's a really good environment

Out by a factor of five or more. A $1 Linux capable ARM: https://www.eevblog.com/forum/microcontrollers/the-$1-linux-... I'd expect that there were even cheaper processors now since it's eight years late

I used decNumber in the WP 34S project ( https://sourceforge.net/projects/wp34s/ ) and more recently in the C47 project ( https://47calc.com ). You are correct in that the decNumber library doesn't su

It might be shorter to do some multiplications: 0x08C0C166 = 2⁴ × 3 × 5⁵ × 11 × 89 + 1 = 10⁴ × 3 × 5 × 11 × 89 + 1 Plenty of values that can be reused (11 = 10 + 1 and 89 = 10² - 11). Still, there is quite a bit of manipulation required and

The initial XOR instruction isn't required, registers are zeroed as per the problem statement.

Later uClinux was available on m68k platforms without memory managers. The approach taken doesn't seem close to the one in the article. I managed to put in shared execute in place library support, the limitation being the number of sh

There is a second issue with the code. The calculation of the mean isn't numerically stable. Instead use: mean_power = mean_power + (power - mean_power) / count

Algol 68 was to Algol as C++ is to C: trying to do too much resulting in over-complexity. The two page spread showing a graph of the implicit type conversions was a masterpiece.

Kind of like the "install this software" as part of the interview process. "My hourly rating for figuring out your bug is $X".

What a crazy idea. Cost to orbit is huge. Power availability will depend on pushing enough solar up there. Data centres use lots of power. Getting rid of excess heat is a major problem in space and data centres generate lots of it. Terre

We're all upside down here and the blood rushes to our heads. While living in the antipodes gives most of us genius level intelligence, it also prevents interpersonal relationships. It's a trade off unfortunately. If you live down

This is the easiest way to go but it's only obscuring the GUID. Format preserving encryption (FPE) would be another possibility if it's not simply a byte string.

Is California one of the more progressive states with regards to reductions? This does not bode well for the world we share.

As a career programmer, I'm not in the least concerned that LLMs will replace me. At least not in the near to mid term future. The key is to have skills that LLMs aren't good at replicating. Writing secure code, numerically sta

It would also be extremely inaccurate. The x^n numerators grow very quickly and digits get lost because unlimited precision isn't available. Likewise, the n! denominators also grow rapidly. Then the series is alternating which means

The only possibility is to cryptographically sign all videos using a White House private key. Using a digest or MAC is not sufficient: it has to be asymmetric (i.e. public/private key).

Yes :) Oh you want a reference. Sadly, I don't remember the text book we used three or so decades back. It was good. The title was simply: "Time Series Analysis". This is kind of a counterexample for Betteridge's law.
