How do you calculate this? Starship has a propellant capacity of 1200 metric tons - 1.2 kilotons. Super heavy booster has 3400 tons, total of 4.6 kilotons, per wikipedia [1]. By weight, you need about a 4:1 ratio of O2:Methane for complete

Sure, but it kind of sounds like the 5 will still be a superior solution, even without hardware support: https://www.raspberrypi.com/news/introducing-raspberry-pi-5/... Obviously, it would need benchmarks, but tak

Is it really a big deal? How many people are doing encoding on the device and can't spare a core for it? I'm sure they exist, but the move from 4->5 will leave them with plenty of headroom, so it's not clear this changes a

Urban sprawl is a feature of _suburban_ expansion at low density. It's exactly the opposite of a dense, connected urban environment. (1) My kids spend a lot of time at the neighborhood park, as one example. It's within walking dis

The spreading is ok but the transport is high. The key thing is: how many years of weathering do you get out of one load of 47 tons (or 27t)? The paper provides a very course estimate that what they measured over the year was only 0.15% of

13% of all toddler deaths by any (non-accident) cause. That's very substantial.

You can measure it with an inline USB power meter. They generally run between half a watt idle and 2 watts depending on what you're doing (using a camera, Wi-Fi, and keeping the CPU busy) and if you've shut down things like the vi

You've gotten some answers below, but one answer is: There are several common ways of handling this, from powerline communication to cellular to LPWAN approaches, and all of them are in use, with different trade-offs. There's no o

It's more about capacity. There are hundreds more public universities than private. The money picture is ... messy and more complex. Some private universities are cheaper for low-income students than public schools (Harvard), some are

Yes, but it's not where most actually go. 75% of degrees are awarded by public colleges and universities.

That's a fun idea. Thanks! Hmmm. And very welcome. It turns 25 this year, which is really weird - it's older than my students! grins

No. I should prune them, honestly. I earn about $100 / month on them; I played around with it at some point mostly to understand the advertising ecosystem. Half of the links to Amazon are broken at this point. My hosting costs are abou

Thank you. :-) I'm definitely a systems programmer, not a UI person. Suggestions or questions welcome, of course, but I usually only spend a day per year on the pi searcher. I re-wrote it in rust last year for fun, though.

Tokio is awesome and I end up using it on almost all of my server projects. But, particularly for library developers, one reason not to just jump on tokio and instead strive for (some, reasonable) compatibility across executors is the embed

You're doing a pretty good job parroting what the incumbent carriers say, but have you actually studied it? UTOPIA in Utah is a good example of a major municipal fiber project. https://en.m.wikipedia.org/wiki/Utah_

Nah. The log crate primarily uses unsafe to poke at pointers in a probably-ok-but-racy way on platforms that don't support atomics. It would almost certainly be better to use a platform-appropriate mutex for those limited contexts, or

FWIW, I threw a few GPU-weeks at this trying, for example, all variants of "[Gg]ive <name> a <noun>" or "[Gg]ive <name> and <name2> a <nice-thing-noun>", with various ending punctuation and

by dgacmu 3y ago
Absolutely. Crates that already use unsafe will be a more attractive target. Most of the ways to sneak arbitrary code execution into rust require unsafe. As I said, it helps. It's not perfect. But there are a lot of crates out there th

by dgacmu 3y ago
These attacks would be very noticeable in a crate that was not already using unsafe. That's a pretty reasonable start, at least - and it gives a little more benefit to reducing the number of unsafe-using crates you pull in. (For non-ru

Oof! Thank you for sharing that. This is one of the reasons that smart bulbs and the like are generally bad - you never want a situation where the switch doesn't just act like a switch. Smart houses should be designed from the perspect

I 99.9% agree with you. Some nitpicks, since this is a discussion of getting units right: mAh doesn't measure "current", because current is the flow of electrons. It measures charge. 2000 mAh hour is redundant - the 'h&#

I too ran a small ISP from 1995-1997 or so, and the biggest gift I got from one of my co-founders was the strong suggestion we use this new cheap database called mSQL [1] as the basis of our accounting system. And I did. I wrote a lot of te

This is not really accurate. OCSes like this have been used for a long time in telecom, and we've proposed their use in datacenters in various ways as research, but this is this the first large scale datacenter deployment that I'm

I'm in a related area and I'd be pretty surprised if this is directly relevant -- are you doing ISO-9001 certification? Right now, they're just offering rust, but with the ability to use it in a certified environment. In the
