IMO, this is much closer to the direction we should be heading.

The typical 4-seat, 1600+ kg, to move around one or two people, at a total of ~200kg, is just stupid. Most of the energy is spent just moving the car... very inefficient.

Also, the environmental footprint of manufacturing modern cars is horrible: metals mining and refining, fabrication, waste from manufacturing, the energy to do it all. Making Li-ion batteries is extremely energy intensive; which is one reason they are so expensive.
Very cool! I wonder if anyone has done something similar but for people and companies in an economy... it's my dream pet project, but I've never even gotten around to researching where to begin.
>The amount of energy required to move x amount of mass is a math problem

If the energy isn't lost to friction then most of it can be recovered. Although I think it's impractical, the Hyperloop concept is one way to reduce friction. Instead of increasing transport speeds beyond current air travel, it could be used at the same speeds but much lower energy cost.

I just realised that "recently" happened at the end of 2018 https://blog.ipfs.io/53-go-ipfs-0-4-18/ - oops.

There was also a change later which turned off nodes being the middleman by default, but not sure which version.

There is no good answer, but, if I were you, I would probably go but keep a close eye on symptoms.

Be aware, that you are probably likely to get hit with a quarantine if everything goes pandemic.

And, if things do go pandemic, you probably want to have seen your parents.

Skip GDC, though. That's just asking for trouble. And it's likely to be cancelled, anyway.
"Red is too alarming, we should use blue" doesn't reconcile with the severity of the situation as far as I can tell.
Oh I see, that makes complete sense.

Basically, given two small arrays A and B (such that both fit in the CPU caches), if the computations to do are sum(A) * sum(B) and sum(B) / sum(A), having two threads that do the computations will be more than twice as fast as a single thread. In the two thread case, A and B will be fetched in parallel (assuming left-to-right evaluation), incurring only one round of pipeline stalls for data fetching, whereas the single threaded case will have to incur two pipeline stalls from memory fetching.
Which terminal lets you do that?

Their issue is GitLab itself, not the runner. And sure, Gitlab is available in forms like a Docker image, but as someone who managed Gitlab for years... it's reasonably high effort.

Additionally, I would not trust Hetzner with anything that gets this much usage. They're very cheap, and they're very cheap for a reason.

When buying colo for a busy application, it's not unusual for bandwidth to cost more than the power and rack. All in all I'd expect them to be looking at at least $2k a month or $24k a year for power/rack/bandwidth. This would be something like an average, there are lower rates available in markets with cheap connectivity but then if the equipment isn't local you end up spending more on smart hands. In many places the rate would be higher.

Then up-front hardware purchase could easily be $50k and probably more. I wouldn't expect to see savings at all the first year, I'd expect it to cost a chunk more. Of course that's not quite fair, the hardware purchase amortizes over at least a few years, but when you're struggling to pay the bills that doesn't make you feel any better.

Renting hardware is an option, but will still cost you more than colo on year for year for equivalent capacity. Dedicated servers from a reputable source start at a couple hundred a month and quickly go up from there. It sounds like their situation will require HA.

I'm just waving my hands here based on my guess of how much usage they're seeing for the $75k they estimate in AWS spend, but I have a quote in my inbox right now from a reputable datacenter operator for $18k per year just for rack/power/x-connect, that's before bandwidth, which I'm going to be paying two different providers for for diversity (and this is still worse connectivity than AWS gets you). That's a full rack, which is a lot of room, but the power/xconnect/bandwidth part of that basically don't change as you go to partial racks so the savings are not really that big. Quality colocation costs real money, and a gitlab instance with that kind of usage shouldn't be running out of a bargain-basement provider.
There's also the problem of Turbo Boost.

My laptop's 9980HK will boost to ~4.5 GHz when only loaded to a single core.

However, when I load up all 8 cores, it might only sustain ~3.5 GHz.

Therefore the 8 cores might not actually result in the work being completed 8 times as fast, only 6.2x (8*[3.5/4.5]) real-time due to the lowered clock rate of each individual core.

This will show up as additional user time, since each individual core is able to do less work for each unit of time (seconds) compared to the single-core case.
I'm not sure, but that person may have been attempting to make a joke about your misspelling of "interpreted".
48V is interesting. It's a fairly safe voltage for humans to encounter. POTS in USA has used it for a long time, and PoE runs pretty close to it. It's easy to buy batteries for backup. As noted in TFA, it doesn't require components as beefy as those with 12V. I wonder if this sort of effort on Google's part could lead to more consumer-level electrical gear with strange voltages? ISTM a modern home with modern lighting should drive all of that with PoE or something else much like it...
Ah, that agrees with my experience, I noticed the IPFS node behaving much better some time in the last year.

Yeah, but bandwidth in a DC is pretty expensive too, it's just billed on a totally different basis. That can actually make these things a bit more complicated because if you're paying for bandwidth on a 95%ile or dedicated basis you end up managing your budget by slowing down everyone's downloads... and that has a real impact on user experience that could have all those projects shifting to a different provider. Getting a big chunk (250mbps? 500mbps?) of dedicated bandwidth will really help you on the way to $75k annually.

If we continually needed more firefighters, and the government either refused to hire them or couldn't afford them, so a volunteer group took up the cause and got people to donate money for trucks and volunteer their time to fight fires...this would cover up the problem sufficiently so that it would seem like "we only need to have enough firefighters to get to zero casualties relating to fire". Which means that we would not have a focus on improving the bad building and furniture regulations.

Sorry, this still seems like a terribly hacky way to think about code.

Again, if you write a template engine or a SQL engine, the code the library's developer writes to determine how holes are safely filled is literally sanitizing input! You never get away from sanitizing inputs, you just do it further from the source and closer to the sink.

> So sanitization of input is a good idea

Right. "Don’t try to sanitize input" is bad advice. Also, the whole point of escaping outputs is that you don't trust inputs. Escaping outputs is done to sanitize inputs.

If by "sanitize input" you mean "add some backslashes to $_GET values like it's 1995", well, I guess, point taken. But then, the actually good advice should be "step back learn how to think more systematically about your code", not "escape outputs instead of inputs!"
I don't think learned is the right word to use here. Github's centralized design and vendor lock-in is quite intentional.

Are Ideas Truly Worthless?
Why is it a meme among techies that ideas are worthless? It makes me really sad that smart people can believe such a ridiculous thing in the internet age.

I'm the author of some ideas lists and I like to share ideas with people. It's what I do. I'm capable of developing some of the ideas but not all.

Some are too difficult. Should I not have the idea? Should I suppress having the idea from my mind? And not share it? Why don't people share ideas more often? They get shut down by their peers and I am sick of being shut down for having ideas.

This meme that ideas are worthless without implementations needs to die.

Ideas are RFCs and ISOs and the ideas of books.
Ask HN: Usefulness of social network data for epidemic management?
So idle question for me since I don't have access to such data, but if one were sitting atop a pile of social network data, are there some useful predictions or even more active epidemic management information which could be produced?

Social connection graphs, with position data, workplaces or other gathering areas would seem to be ripe for analysis to to give an organization like the CDC better forward predictions of how a disease like COVID-19 might specifically spread. Could you use that information to get ahead of it by prepositioning resources, or using targeted notifications or quarantines?

How would you approach it?

Despite the headline this is still just speculation. But it is a pretty obvious bet at this point. The iPad pros are so fast, and have serious physical limitations compared to laptop and especially desktop computers.

Is this the common case? It would seem logical that most content makes the most amount of money soon after it comes out. I think for many kinds of content, the first week makes about as much as the rest of the lifetime of sales.

And even in the rare case where some content becomes rediscovered after the 30 years, the creator simply needs to create a sequel, which by having their name attached to it, will be recognized as the official continuation.

With respect to the ‘early communism’, there is a very large caveat. These ‘communal’ groups where ethnically, racially, and culturally homogeneous ‘small’ (by modern standard) people groups who where by in large extended families. There is no comparison possible between that type of grouping and modern human society. Humans might be willing to miss a few good meals to ensure my kids or parents where provided for, but En masse won’t lift a finger for their neighbor neighbor, let alone someone in the city or state next door. Hence why leftist social policy at scale has always relied on strongman authoritarian leadership in actual practice.

My issue is, I need an editor that knows that a field annotated with @Resource with a type and name of SomeService foo is injected by a DI framework and makes it easy for me to navigate to implementations of SomeService with a name of `foo`.

Sure, I could put hundreds of hours into half-way replicating what an IDE does. Or, I could just use an IDE that was written by people who've felt the same pain as me. TextMate might be good for the occasional Ruby or Python script, but even then - do I have to manually manage virtualenvs while working on this script, or can my IDE do it for me?

The thing about needing cpuid isnt true except perhaps on some older AMD hardware.

lfence works as a execution barrier and has an explicit cost of only a few cycles. You can accurately time a region with something like:

lfence
rdtsc
lfence
// timed region
lfence
rdtsc

This will give you accurate timing with some offset (i.e. even with an empty region you get a result on the order of 25-40 cycles), which you can mostly subtract out.

Carefully done you can get results down to a nanosecond or so.

rdtscp has few advantages over lfence + rdtsc, and arguably some disadvantages (you can control where the implied fence goes).
Yes, plenty, including Google.

If anything exceptions are declining in popularity, due to non-obvious and non-local effects.

Exceptions are an uber-goto, that can jump outside entire functions. Some people still like that, but very disciplined code bases (of which there are a lot in C++) tend to avoid them.

At the very least, utility libraries like this one tend to err on the side of most compatible: header only, no exceptions, user-chosen allocators, etc.
