It's a response to Bezos's Blue Origins tweet. Getting to orbit takes far more energy than just getting to orbital altitude, which is the main point Musk is making.

Blue Origin isn't a serious competitor, though. United Launch Alliance (Lockheed-Martin and Boeing) is the real competitor. It's amazing that they're still using Atlas/Centaur, which, although there have been major redesigns and upgrades, first flew started in the 1950s. (Yes, the current Atlas is really a new design, using Russian engines. The Centaur upper stage hasn't changed as much; it still has the 1950s Rocketdyne engines.)

Space-X still wants the capability of landing on the barge, so they don't have to expend so much fuel to kill the horizontal vector and get back near the launch point. They may end up going with expendable boosters when lifting to geosync orbit. But they may be able to reuse ones recovered from previous low orbit missions.
I remember studying `Computer Systems: A Programmers Perspective'[1] in my undergrad which was pretty good and covered how programs look in assembly (calling conventions, call frames, data representation, assembly ...).

Also, to get better understanding of x86 ISA I followed the old i386 manual[2]. Its old but much more smaller. Perhaps once you feel comfortable, you can move to newer manuals. I never read newer ones (because I never actually needed assembly for any project, was just studying for fun).

It always amuses me to see how science has taken hold in every part of life. Maybe not science per se, but the idea of action/reaction, of doing something to gain something. You know, not for the pleasure of it, not because we feel good or it's the right thing to do, but because "it says so in the paper", "it boosts productivity" or "lowers the risk of diabetes by 5%, studies have shown". That's just fascinating.
> I do think that many people would be better off doing a tour of "civil service" in retail or food service before going off to fancy jobs.

A thousand times, yes. I've moved into 'devops' from support, and it's just as clear on this side of the divide just how little esteem developers have for support staff.

One bit of schadenfreude from the past: I worked in a 2-person support team in a small company, and constantly had requests for improvements (both support- and client-friendly varieties) rebuffed, basically with the 'eh, what would support know about products' attitude[1]. I ended up leaving that place, and the other support guy had already booked a month-long sojourn on the other side of the planet, leaving the developers to now support their own product. The company ground to a halt and no-one could do a thing as the half-dozen strong dev team struggled to do support with the shitty environment they gave us to work with. Apparently on the other guy's return, better support tools shot to the top of the devs' priority list.

I also remember hearing about a wine distribution company in Western Australia where every new hire, regardless of position, spends a week half on support calls and half in shipping, so that everyone is exposed to the difficulties of packing and shipping wine, and dealing with customer breakage. I love this idea, and wish it was more widespread. Dealing with the public is hard, but there's not much you can do about that. Dealing with the undeserved contempt of your coworkers is also hard, and it doesn't take much to expose people to the more human aspects of the crappy positions in a company; raising empathy can really help.

[1] I've always found this bizarre, that the department that has the most client contact when something goes wrong is so routinely ignored when developing the product further.
I'm not aware of any scientist that 'opposes LENR', I am however aware of a lot of scientists (and lay-people for that matter) that are skeptical of Rossi. And most scientists will take a much harder look at anything LENR related before committing their names and reputations to it leaving the field wide open to the fringe, with predictable results.

It's not dis-similar to how people working on AI would call it anything but AI for a decade or so in the IT business. The AI winter had a very good reason: being oversold makes a field toxic.

Who are these people who can nap at work? I mean, how can they physically do it?

I hear people complain about not being able to get a good night's sleep in their bed at home. The phone doesn't ring any less during the workday. And who has an office these days quiet enough for sleep? (As if anyone other than founders gets an actual office. Shhhh... Type quietly. It's the boss's nap time.)

I was in SF a couple weeks ago and had trouble sleeping even in the hotel. Does anyone in SF not drive a firetruck? You'd think the whole city burnt down every night. The concept of tech workers napping mid-workday reminds me of those scenes in My Cousin Vinni.

This is a great example of the government being inefficient at getting things done. However in this case, this ended up saving tax payers money by having inmates released early.

the other issue with phabricator is workflow. The way I think (and most other people) is on a repo basis - all bugs, reviews, wiki is contained within a repo level.

However phabricator maintains different "applications" - bugs, repos,etc. so to look at the bugs for a repo, I have to go to the top level, click on Maniphest (the bug tracking "application" ) and go to the project and then click on a bug.

At least for games, there might actually be a way to approximate this - PS3 could not be cracked to run pirates games for quite a while. And had a comparable rival console - comparing sales/piracy amount could give us a clue about the numbers, though it would be limited to this particular media type. Anecdotally the friends who had PS3s tended to actually buy those games, ending up 2-4, while the ones with chipped/cracked consoles had an order of magnitude more...

Yeah, I don't get this. To overcome the Coulomb barrier at room temp (source: http://zidbits.com/2015/05/how-does-fusion-power-work/) is akin to claiming you built something which goes faster than light. That's why the term "cold fusion" has such a stigma attached to it, it's literally on the same physics defying level as perpetual motion machines.

Because of the stigma attached to the term cold fusion, they have now switched to calling it "low-energy nuclear reactions" or LENR. It's the same exact thing, just a fancy new name to attract naive & moronic investors.
However in this case, this ended up saving tax payers money by having inmates released early.

I hear this a bit but it doesn't seem include the cost of having criminals in the streets. At least some of them will re-offend and the sooner they're released, the younger they will be, the likelier it is that they will. With a few months across 3500 people, it can add up.

Even if they commit a crime which you believe shouldn't be a crime (some drug offence), they will consume a lot of resources while going through the legal system again.

Not to mention the legal mess this bug created that will need to be sorted out now. Highly doubtful that there were any savings here. Knowing the government operations, you'll end up paying even more.

What authors point out is not trivial observation that programs are running on
finite-memory machines and thus cannot be Turing complete. What they do point
out is that even if C programs have been running on infinite-memory machines
the memory accessible to C programs is still bounded.

In general I would agree with authors on this point as long as we exclude
external storage. They also hint that, while it would be trivial to provide
interface to infinite memory tape, the standardized part of file I/O does not
seem to do that. They claim that it is prohibited by bounded return value of
ftell. I would disagree, because ftell may return an error value in this
scenario as well. Moreover to access infinite tape you don't even need ftell,
relative movement provided fseek suffices.

I'd like to be lazy and call this a core-competency issue, but you'd think if anything would get a corrections office to back some software work, it'd be the possibility of erroneously releasing inmates. I really have no explanation for this aside from simple negligent stupidity.

That's quite a pessimistic view. But if you genuinely believe some will in fact commit crime again and therefore add costs to the legal system, would those costs still be more than the taxpayer cost of room and board in a prison for 2 months?

And if, say, 10% were repeat offenders, how does this factor into the true "costs" of the legal system dealing with them, vs. the 90% who saved taxes by getting released early?

I think you'd be surprised just how much of a tax burden keeping people in prison truly is. And I think for many crimes, the odds of one of these released inmates committing crime again is much lower than you suggest. And even if they do commit a crime, that 55 days early release is going to make much difference.
I'm an American; it strikes me as an overloaded expression, used to imply both "bullshit" and "testicles", plus whatever the Sex Pistols were on about in their album title...

> I don't think it's fair to lump those two together.

Heh, I disagree. I hold almost the exact opposite view and believe it is perfectly fair to lump those two together. Cold fusion requires overcoming the Coulomb barrier at room temperature. Do you have any idea how impossible that is? It's just as impossible as accelerating an object faster than light, or me spontaneously quantum tunneling through my floor into my basement. So yes, perpetual motion machines, unicorns and cold fusion all belong to the same area of science and deserved to be lumped together.

Your arguments are against providing exact pricing, that are rather obvious. The discussion seems to be about ballpark estimates. I'm not sure how to display this, but something along the lines seems reasonable: "Moderate installation at local high-school should fall under 1M, while a state University might get basic feature-set for 10M".
Large enterprises have whole departments for price-bargaining, but the smaller ones and especially public ones want to know the ballpark before issuing an RFP

> This is a great example of the government being inefficient at getting things done.

I don't see any reason that "being government" had anything to do with this category of error. I'm also not sure that "inefficient" describes the problem.
Reminds me of a great newspaper investigation in Nebraska a few years back. A journalist heard a story of an inmate who got released significantly early and so he and a data reporter scraped the prisons web site and, by doing simple math based on the scraped fields, found that hundreds of inmates had been wrongly scheduled...it wasn't quite just a software error, but a too simplified formula that someone stuck in the system and apparently no one bothered to double check things http://www.omaha.com/news/metro/world-herald-special-investi...
I've been using GitLab before, and use it from time-to-time still, but I've moved over to a self-hosted Gogs[0] server with Drone CI[1]. Both projects are actively maintained and both runs super well in Docker. Gogs is almost an identical clone of GitHub, although some small parts are missing but will most definitely be added in an upcoming version.

Gogs is a lot more lightweight and faster than GitLab is. Our previous GitLab instance (7.X version range) used over 1.7GB of RAM (roughly 15 repos with 3 users) and always took longer than 1 second to serve a request (commit browsing was really bad, >5 seconds to serve such a request) while our Gogs installation uses 15MB and always serve requests sub-second. Both ran on the same hardware, with RAID10 SSDs.
Definitely worth checking out if you want a self-hosted, lightweight & performant Git remote solution.

Drone officially supports Gogs as well, so that's nice.

You cannot ever be sure how changes to the public / protected API from a class affects classes down in the inheritance tree.

Specially bad is when methods that were never supposed to be overwriten change their semantics, leading to erratic behaviour on classes that have overwritten them.

You missed the point. I said even if the process turns out to be something other than fusion, interesting phenomena like sonoluminescence are still worthy of study anyway.

Same with this E-Cat stuff, clearly there's something we haven't formally explained yet going on, and the experiment has been shown to be reproducible, sounds worthy of study to me, even if it turns out to be a different process than fusion, and even if it turns out it can be explained without changing our scientific models.
