There's no sweet spot I've found. I don't work for Cloudflare but when I did have a status indicator to maintain, you could never please everyone. Users would complain when our system was up but a dependent system was down, s

While it has nothing to do with how responsive your mouse feels, as that is measured in milliseconds while CAS latency is measured in nanoseconds, there has indeed been a small regression with DDR5 memory compared to the 3 previous generati

Disclaimer: This is only an educated guess based upon public info. Also, it's impossible to make something truly unspoofable, but it isn't that hard to raise the bar for spoofing pretty high. There are two additional concepts buil

There's actually a lot of combinations of (domain, type, protocol) that are available. It is not always the case that the protocol implies the type. In IP land (domains AF_INET and AF_INET6), we have the well known UDP and TCP protocol

There are some crossed wires here. AES-NI is x86-specific terminology. It was proposed in 2008. SHA acceleration came later, announced in 2013. The original version covers only SHA-1 and SHA-256 acceleration, but a later extension adds SHA-

Also, rather importantly, the L1 i (instruction) cache is still only 32 kB. The part that got bigger, the 48 kB of L1 d (data) cache, does not count for this purpose.

Fair, this is a good example of when != is actually the right choice (instead of !==). However, on web browsers, this will log an assertion failure to the console, but it will not throw an exception. It's also not suitable for the orig

Assuming assert existed, it would almost certainly be judging its value for being falsy , while the ?? operator judges its LHS for being nullish , which is a narrower category. For strings, this affects whether the empty string is accepta

Also, incandescent lightbulb lifespan is reduced by repeated power cycling. Not only is the legendary firehouse bulb very dim, it has been turned off and back on again very few times. Leaving all your lights on all the time would be a waste

Both stories can be true. The firms can coordinate by agreeing on a strategy they deem necessary for the future of the industry, and that strategy requires significant capital expenditures, and the industry does not get (or does not want)

Go has a precise garbage collector that knows where all the pointers are. So while yes, []byte is a (fat) pointer, the GC is free to move its target to a new location, as long as it updates all the pointers to it. This means that you may ob

This only wipes one copy. The GC is free to move the allocation around, and is not required to clear the old copies.

I must disagree. Destructuring is nifty, but it is almost completely unrelated. The second value in any of the builtin two-value assignment forms is invariant on the type or size of RHS; it's always a boolean, and its meaning relates t

by kbolino 11mo ago
Right now, type casts (called conversions in the spec) always produce a single value. The idiomatic way to have checked casts would IMO be a two-value form, as this would be consistent with type assertions, channel receives, and map indexin

I didn't mean to imply otherwise. But, as you say, this is equally applicable to IPv4 and IPv6. There were a lot of issues solved by IPv6, but "have even more room for non-TCP/UDP transports" wasn't one of them (and

by kbolino 11mo ago
IPv6 uses the exact same 8-bit codes as IPv4. It uses them a little differently -- in IPv4, there is one protocol per packet, while in IPv6, "protocols" can be chained in a mechanism called extension headers -- but this actually m

Yeah, the problems seem to largely be ergonomic. As another example, the exception type hierarchy doesn't pull enough weight. Exception is the base class of all checked exceptions and RuntimeException is the base class of all "ord

There is a middle ground that I think the post glosses over, which would be to split apart the Result<T,E> value whenever its two cases differ significantly in size. You'd also have to track the discriminant of course. Basically,

But the argument is not about adding exceptions to the language. It's about borrowing a technique from languages that do have exceptions (and Rust's own panic unwinding) to implement Rust's existing error handling without m

There are two issues here. If the CDN is so poorly interconnected with Vodafone that there's one bottlenecked link, then it's not really accomplishing its job, at least as far as "inside of Germany" is concerned. It migh

It is mostly the middle, and not either of the endpoints, that is the real problem. You have a 1Gbps link, the Netflix DC you're reaching probably has multiple links with aggregated bandwidth measured in Tbps, but at some point in betw

You're both stating things that are a bit beside the point. Pure Go code uses registers to pass function arguments whenever possible. Large structs and/or numerous arguments can still spill onto the stack, though. FFI (cgo) uses w
