The only thing that got hacked to pieces more than the English peasantry during the middle ages was the English language.

It only took 200 years for 200 of those 260 languages to be lost or brought to the edge of extinction. It's at least plausible and to me quite believable that the arrival of a group with a technological advantage 4,000 years ago could

It looks pretty typical for BASIC of the late 70s to me. You wouldn't want to waste characters on commenting code: machines of that era would have only a few KB of RAM, as low as 1K. For the same reason you don't want to waste cha

Institutions often reward publication in more impactful journals, and careers are built on your publication history. Journals also often require that you assign copyright to them and restrict your ability to publish in more accessible place

There is so much to dig into for one short article. So much. Too much for an HN comment, I think. A few bullet points: - It's not an event sourced system, it's a relational system with an absolutely terrible audit log. - The audi

Yes, that's true - I may have to reconsider which one I think got it the most wrong :-)

You don't need to expunge c89 from gcc for progress to have happened - we've got c99 and c11 and whatever c17 is or isn't already there. Effectively, however, python2 and python3 are different languages. Since they're in

I am interested in the convergence of AI-generated code and programs-as-proofs: can I work together with AI using a language with a highly expressive type system such that we co-develop a specification in types and properties, then co-devel

I don't think the halting problem's got anything to do with it, because I certainly also can't prove, in general, whether some code I have written halts or not either but that hasn't held me back from churning out vast q

I'm very far from an expert in this field, sorry. PCM (and other resistive memories) are definitely still a thing, though - they've been used for in-memory computation, doing vector-matrix multiplications directly in the memory ce

Not really, no. For a start, I don't think NAND flash itself is an example of planned obsolescence: its main predecessor is spinning rust platters, which were notorious for sudden catastrophic failures. Spinning rust replaced, more or

One reason come to mind: Conway's law. If you have a monolithic team a monolithic server is usually a pretty good solution to a problem. If you have multiple teams you're likely to wind up with an architecture that lets them work

How does one make the leap from "a source available but otherwise proprietary license" to a copyleft license? As I understand the terms, perhaps in too limited a way, a proprietary license is never one in which others are free to

I find your comment a bit perplexing, perhaps you can help me understand. Why do you want to release code on GitHub with an oppressive license? What's the motivation for you, and what's the benefit for anyone else in it being rele

> Banning a /24 doesn't have too much collateral damage. Even at 128:1 CGNAT ratios a /24 has 32,768 potential users. By comparison, a /56 has 256 potential users on a /64 each.

by codebje 4y ago
Collateral damage is accepted for CGNAT, which is widespread already, and will be equally well accepted for v6 /56s (or /60s).

The difference is typically between a static _public_ IPv4 address or a dynamic _private_ IPv4 address, and CGNAT sharing public IPv4 addresses across subscribers.

If you're already doing base index addressing (eg, [SI + DI]) you're already using the ALU to compute your memory address, and it's not _that_ much extra wiring to have the ALU support either a constant power-of-two displacem

Well, maybe, if the specific use case of 1-based arrays was all that got supported. It'd be a pretty huge waste of processor design space to do that, though: if an HLL wants to support n-based arrays for n != 0 it can just store the ba

Like TFA suggests, right at the end, this is where code review shines. Keeping documentation valuable is a discipline challenge, and we all fail from time to time at keeping ourselves disciplined. If you have team agreement on the level of

I meant that rationals are a subset of the reals, and while floats are also a subset of exact reals a "typical" fixed bitwidth implementation will have a significantly greater range in floats than rationals. I don't know that

General purpose programming languages are complex tools. In this specific case representing non-integer numbers effectively on a binary device is complex. If you use a different representation than IEEE floats you just give a different set

In a broad sense, sure.

Every option here has tradeoffs and drawbacks: fixed point arithmetic suffers from a very limited precision range, rationals aren't even the same number set, cauchy sequences are precise but comparatively very slow… there's no one

Are the exchanges local, or is he doing an international money transfer from the exchange anyway? Trying to find where the value offered by the crypto is, but every way I can see for this to work still involves an international transfer.

"Effect" is perhaps a broader notion than one might think: it's an effect to write to a file or mutate some variable, sure, but it's also an effect to raise an exception, goto a label, raise an exception, execute asynchr

If you're not even slightly familiar with that branch of mathematics it's still a perfectly good and descriptive name, because you can search for the term and get loads of relevant information from the programming side of things.
