For anyone wondering "why", this linked article in the source gives some background, https://blog.westerndigital.com/storage-architectures-zettab... So instead of SMR harddrives and SSDs doing extra work to hide t

In general Rust emphasises semantics over implementation side-effects. For example you use a pass-by-value because you're semantically moving ownership of the value to the function, not because the implementation may be faster/slo

You should be careful trying to apply these micro benchmarks to modern optimising compiles, behaviour may be different depending on the exact code being compiled. Rust especially has immutability and known types in generics at compile time,

The functions/symbols being used were __kernel_fpu_{begin,end}. These were designed for use within the kernel, and not for external modules - however external modules used them since there was no other alternative. At some point the ke

The popular Raspberry Pi platform only started shipping with a 64-bit ARM cpu in 2016, and ARM chipsets with 64-bit support only started appearing around 2012/2013. So I'd expect many new embedded platforms to continue using 32-bi

Thanks, I didn't realise that. I need to do some more reading about the topic.

Cryptography is based on "hard problems", something that is easy to solve one way, but hard the other way. Quantum computers provide algorithms that can severely break some of these (namely RSA with Shor's Algorithm https:&#

When you're deploying multiple APs you also want to turn down the broadcast power on them. If the signal of multiple APs overlap too much, clients won't roam onto the next AP in time. Also don't be afraid to hire someone to d

It does have an interesting effect though. Apple now have a mandate that apps must work in IPv6 only mode, so they need to be developed and tested for it. This in turn means they need an IPv6 network to test it on, giving enterprise a reaso

A lot of captive portals use HTTP interception/redirection, returning a 30X status instead of the expected 204 status.

I'd be surprised if they didn't have some form of rate limiting. Here are some reasons Google DNS does it https://developers.google.com/speed/public-dns/docs/security... .

by keeperofdakeys 9y ago
Be careful with that, Google DNS (as an example) will start ignoring your DNS requests if you go over the rate-limit. Not an issue for home users, but an issue for any sizeable business.

Instead of fetching the secret via a direct HTTP call, the secret is fetched from the DNS server (eg. _acme-challenge.example.com.) - where the DNS server is usually separate from the server getting the cert. This can be done with ACMEv1 fo

ASN.1 has one of the same problems of XML - the data format is far too strict. Many libraries work by generating new structs/classes from the specification, which is a real problem for an agile workflow. The "struct" type als

The web package definitely originates at the origin, but is it up-to-date? While I assume the web packages have expiry dates that the CDN servers would respect, this doesn't give the full control that Cache-Control headers do. And in t

Even with these changes the top bar does serve one purpose, it tells the user that "something is different about this page". One thing I fear is visiting a web page, and having no hints that the content wasn't loaded directly

I have an older one of these, and you can get full root on them. They are basically stock IIRC, if they aren't they can at least run stock openwrt. By default they have a simplified second web interface, with an "advanced" bu

If you use `git commit --fixup=<commit>`, then the new commit will be automatically moved, and given the "fixup" action when doing an interactive rebase. (Same for --squash). This means you only need to match the fixups to c

As a species we're still part of the food chain, we depend upon plants and animals to survive, and we're full of microorganisms. Some of the long lasting consequences of the Chernobyl disaster in this respect are quite worrying -

Yes, some valid code won't pass the borrow checker. But at the same time, far more invalid code doesn't pass it. Personally I see it as a tool to help me reduce possible runtime errors, and instead have them as compile time errors

by keeperofdakeys 9y ago
Removing the borrow checker would allow you to compile broken code (eg. use after free, data races). However given code that compiles on rustc - passes the borrow checker - you don't need to reverify the borrow checking to get correct

Rebases and merges don't work well together. By default, git rebase will get rid of merge commits. While there is an option to preserve merges (-p), it can lead to some strange behaviour while doing an interactive rebase - see BUGS sec

I like most if the new tools, but the 'ss' command produces output that's hard to skim. When outputting to a terminal it tries to justify the columns, hiding some information on the next line. When you pipe it through cat (so

ZFS is definitely still a thing. With the creation of the OpenZFS project, and the Linux port, the future is looking bright.
