Instead of TODO, I often add a NOTE instead now, e.g.: NOTE: Attempting to re-synchronize here would cause an infinite loop because... This prefix distinguishes such info from normal comments, which exclusively pertain to the code-a

Man, I was hoping this would be about how sleeping outside is better for your health, and how to achieve that comfortably in the modern world.

Here's a simple example: Say that your server has an admin login that simply compares the submitted password to "thisistherootpassword", one byte at a time. The attacker starts by trying "a","b","c&qu

Sad but true. This is why I'm hopeful that Zig will add support for "constant time" blocks: https://github.com/ziglang/zig/issues/1776

The main goal here is security against side channel attacks, not performance.

To elaborate on my snark, this doesn't work because: - Whitelisting my messaging app means I'd still get pinged for non-emergency messages - Enforcing the block at the software level makes it too easy for me to disable it when the

I looked into getting a pager recently; my plan was to disable my household internet completely for some number of hours per day (by plugging the router into a Christmas tree timer!), keeping the pager around for when my team needs to reach

Even today the M1 still feels slow occasionally -- hanging for a second or two, browser taking multiple seconds to launch, etc. Granted, that could be due to I/O or power management, but in any case it's clear that software is not

I've always found PEM/ASN.1 to be rather ugly. I encode my ed25519 keys as "ed25519:<hex key>".

Presumably the argument is that a storage host might dutifully provide proofs of storage, but refuse to actually transfer your data to you later. This is true, but it's also true of centralized storage providers. The difference is that

I don't mean to suggest that at all -- I have great respect for those people, particularly Rich Hickey, whose framing of "simple" vs "easy" is vital to these discussions. But it's clear that a language like Clo

Safety and correctness certainly are important -- but they're also orthogonal to maintainability (among other values)! It's good to have most of the core values in common, but a language's guiding principle manifests in many

By "north star" I mean the guiding principle that other aspects are sacrificed for. A heuristic might be: "[Lang] would not be [lang] without [aspect]." I'm sure that the Rust team wants Rust to be a good language f

I don't know much about Eiffel; do you know of any articles or talks that discuss its design tradeoffs?
256.
by nemo1618 5y ago
I actually don't think this is true, which is kind of nuts. Programming languages generally fall into two categories: 1) They were either designed by one or two eccentrics, and thus contain a few great guiding principles and many quest

I think you have this backwards. Go is explicitly optimized for software engineering ; in fact, it's the only language I'm aware of that makes large-scale engineering its north star. Here's Rob Pike discussing how Go's

If you have the other avatar available for comparison, you don't need to do so visually -- the computer can compare the raw bytes directly.

by nemo1618 5y ago
That's a good idea! Although, it could still potentially backfire for the same reason as scrypt; now if an adversary is able to obtain your nonce, they are much more likely to fool you. I guess my broader point here (which I neglected

by nemo1618 5y ago
In the adversarial case, yes, there is. I agree that avatars help you distinguish among ~a dozen users; what they don't do is provide strong guarantees that the person you're talking to actually is who they claim to be.

FOLLOW-UP: It occurs to me that, actually, plenty of humans could definitely clear my "higher bar." All you need to do is memorize a 64-character hex string, which is difficult but completely doable using a memory palace or simila

To be honest, I have no idea how many distinct objects humans can distinguish between, but I am 99% confident that it is fewer than 2^128, much less 2^256. I suppose it's a somewhat nuanced question, though. For example, if I were show

The problem with hash avatars in general is that people want to use them for identity verification -- and humans are wired to do so automatically -- but technologically, they cannot provide this. The space of possible avatars (2^256, in t

Personally, I've only seen this crop up in one place: structs that signal optional fields via pointers. Are there other usecases?

In practice, no one will do this, unless there happens to be a function with the correct signature already available. The lambda syntax is so verbose that it's easier to just write the for loop. Another problem is that tons of Go funct
