One big global write lock in LMDB maps pretty well to one single stream of replicated log entries in Raft, IMO. And logical address space is still far in excess of what most disks or arrays can fit, right? 40 bits or so on linux? EDIT: 47

Why are they using RocksDB rather than LMDB? If it's based on Raft, then it sacrifices availability if there aren't a quorum of nodes online.

Both. If you deal with a value type (struct or primitive) and never take the address of it, it can't exist anywhere besides the current stack, value types are copied if you return it out of a function or call another function with it.

Awesome. I think the ability to write a nice .h file, in particular, will really be the killer feature for Rust as "better systems language". Exporting headers and symbols for higher level languages in a format that's unive

Is there a capability or plans to be able to export a header file from Rust code that C code (or Python, Go, whatever) could reference? I couldn't find anything when searching for it but it seems that it'd be possible since Rust

Why not just price it as $/month for X transfer, with $/GB above that rate? That'd be simple, transparent, no damage to the market structure of internet businesses, no future anti-trust cases, and we're straight-up payi

I'm about as ok with paying $100 for internet as I am with paying $4/gallon for gas during the summer. Read: not very. But that's what it costs. Make it clear to the consumer what things cost and they'll either curtai

First off, most of the things you're taking out of the monthly were already factored into the fronted cost in the linked article. Second off, if Verizon does that shitty of a job of cost control compared to foreign government bureaucr

Nobody's asking them to build this stuff out for free. I'm cutting a check north of $100 to Verizon every month, last I checked. And that IS them capturing some of the money generated by services running on their infrastructure.

Because they're arguably the company most invested in an open internet. 2/3 of internet users are google users (made up statistic). That means that they're losing 2/3 of whatever if the internet is hurt. If they'r

Last time I checked and did the math, I counted about 500 bytes of overhead in a java BigInteger. Still, I wouldn't call that "java being slow", more, "java having a god awful BigInteger library class".

There is of course the natural monopoly concern. Pointing out that it's not bad enough in facebook's case to warrant regulation does not obviate the fact that it's clearly very, very bad with the telecoms, who for some crazy-

I think the key distinction there is how unique is the site/project. Is it something that fits naturally in a CMS? Then for god's sake use a CMS. If it's something that doesn't fit naturally, it's just as much ef

I wasn't using it, but it had a reputation for being slow and for the replication being considerably more broken than MySQL's -- apparently both of those have come a long way since.

MySQL is the default sane choice for anything not 'big data' that was started before the year 2010 or so, and hasn't exactly disappeared since then.
