I'd expect the first rocket, or several rockets to actually stay on Mars at least for a while.

1. It means you have somewhere to live and even if you set up habitats it acts as a fallback habitat.

2. You'll need a return to Earth option if things go potato shaped.

3. It can manufacture fuel in advance for future visiting ships so acts as a backup to their Sabatier reactor and other important systems.

4. Once you have several, you can afford to risk using one to travel to other parts of Mars and back to get science from other biome... er.. I mean prospect for resources.

I wonder if these will be capable of operating automatically. It would be nice to be able to prove out the system by sending an automated cargo only mission there and back, or maybe with a skeleton crew. It's fascinating that they're aiming to go directly to this without any less ambitious manned vehicles and missions first.

> It says "Linux binaries are static executables" [0].

They are. Running `ldd` on cargo doesn't confirm or deny this. You need to run `ldd` on the binary distributed:

$ curl -sLO 'https://github.com/BurntSushi/ripgrep/releases/download/0.2.1/ripgrep-0.2.1-x86_64-unknown-linux-musl.tar.gz'
$ tar xf ripgrep-0.2.1-x86_64-unknown-linux-musl.tar.gz
$ ldd ./ripgrep-0.2.1-x86_64-unknown-linux-musl/rg
not a dynamic executable

This is not the default output on Linux. You need to compile with musl instead of glibc: https://news.ycombinator.com/item?id=12565268
I have tried most of them and feel largely the same.

HN seems in that sweet spot for me where it is large enough to have a good amount of discussion but still has very good quality.

Most "reddit but more free" sites turn into imzy or even worse voat. G+ communities are too small for me, and finding a good community is proving to be hard. And I've given up on reddit for any larger scale technical discussion (there's just too much vitriol and "my team is better" sentiment there. It always seems to focus on the negative, and creating a "positive only" subreddit seems like a bad idea, and it attracts the users that will fight that idea on principle)

I'll need to try Ello though. Have you looked at lobsters? It's much smaller than HN but also more technical (and with its own share of bias against anything newer in my experience)
Best idea ever. Lets use Facebook for our business conversations and pay them for that service as a bonus. If you bring this up as an option in a business conversation, i don't want to work with you.
I think this young programmers cult is more US centric problem. Or should I say SV centric problem. I didn't notice such widespread age discrimination in Europe. I'm not that old yet (30), but I've worked with many older programmer/engineers (40+) in several companies and most of them were highly respected, well-paid and got tons of other job offers. Sure, if you are stuck in eighties programming with Assembler only and dismiss C as high level language, don't blame anybody but yourself..

I don't think you deserve the downvotes, it seemed like a genuine question.

Becoming CTO (or in general, moving into management) is not for everyone. That said, in practical terms it behooves the early/mid thirties developer to have some kind of plan to mitigate age discrimination. Consulting is a good half way point.

No, you're actually wrong, IIRC.

The other systems still fundamentally do init's job, as well as managing services. They DON'T do everything, including:

-replace cron

-handle dynamic device files (udev's job)

-set the hostname

-replace syslog

-replace inetd

-automount

-anything I forgot
I think it can be tough to move to SV for someone who is married with kids. That is what has stopped me from applying, and I have definitely thought about creative ways I could make it work logistically. :)

AIX, HP-UX, Solaris and NeXTStep were not written by the original authors of Unix and its philosophy.
Linux has always been closer to the philosophy than many of these, actually. So much so that it has imported concepts from the successor of Unix, Plan9. Linux's procfs which exposes sysinfo as files within the filesystem is a concept taken from Plan9, which was the OS people like Ken Thompson and Rob Pike envisioned as the future of OSes and replacement for Unix.

Those "traditions" you're speaking of not only are not outdated, but they never were fully realized to their ideal outside of Plan9, which attempted to make everything accessible through file APIs.

The suckless crowds are not about reproducing the original Unix. They are about carrying the torch of that philosophy, and the original unix was just the beginning, not an end in itself.
Here's an example of software from suckless that follows Plan9 :

Yeah, I'm not quite making the connection between React and what appears to be a spring water or lava source.
They built many. runit, s6, nosh, bsdinit, openrc.

But yeah, it is being blamed for bloating init, because for one thing, cron isn't init's job. And that's just the start.
It's not about outright banning, it's about limiting to the minimum amount required to perform the service.

Much appreciated. I've updated my prior comment to reflect the correction.
Where Jira really shines isn't in moving tickets along a man an board.

It's in supporting the metadata that allows your engineers to quickly refer to a ticket (by number) and your project manager (or whoever serves that function) to search and filter the ticket inventory to find what needs their attention.

I've always worked on small teams. I've tried almost every issue tracker I could get my hands on. Yes, even Trello (or <shudder> asana) is better than nothing. But once we've got more than 2 engineers or more than 50 tickets in our backlog (500-1000 is a pretty normal count for a company that's been around more than a year or two), I invariably find myself wishing desperately for this or that feature of Jira.

The problem with Jira is that it's designed to be customized and locked down for the most rigid and enterprisey of large corporations. The configuration is insanely complex and has a ridiculous learning curve. And the amount of process it introduces in its default configuration is indeed way too much for a small team.

But if you're willing to spend a day or two adjusting it, you can set up a Trello-like workflow while still gaining features like advanced ticket searching, automatically reassigning tickets on status change, release tracking, web hooks for CI and version control, multiple views of the same data, bulk operations, man an board swim lanes, and other conveniences that will make your PM and devops people more efficient and less frustrated.

Those things aren't distractions from your users' pain points. They're features to address your own team's pain points so that they can focus on the users' pain points - instead of spending their time wading through poorly organized information and their energy trying to make sense of that information.
Honestly, even as I'm getting older, this isn't at all obvious to me. Someone with five years solid experience with web development might very well be far more effective than someone with twenty years experience of working in corners of large companies with various technologies, especially when you consider the expected salary.

I think it good that people are talking about these things, but sometime it seem like people think it's a big conspiracy, rather than a factor of how the ecosystem and market looks.

OMFG. I guess that mr Musk won't have any problems in finding manpower to execute his plans. HN is full of experienced deep space and terraforming specialists. =)
Perhaps it's anecdotal too but I work in mainframes (myself being 38) with both younger and older colleagues and the ones that are older seem to be far more focused and determined (perhaps "work ethic" is the most apt word for it) than the younger ones. I can even feel it myself looking back.

You forget that Musk envision a public-private partnership for his insane project. That means public money will be involved.

I don't mind Musk building an interplanetary rocket. I even agree with him that it will be useful to visit other places than mars. But his project to build a "self-sustaining city" on mars sounds ludicruous to me and I don't wont any tax money to be spent in it.
You can sort of ballpark the bitcoin energy usage by assuming all mined coins are sold at the current exchange rate, and used to buy electricity at a reasonable average for the world...

12.5 BTC every 10 mins => 12.5 / 600 per second => 0.02083.

0.02083. * $600 = $12.5 / sec

Assuming electricity cost of $0.10 per kWH...

%12.50 / 0.10 = 125 kWh / sec.

125kWH * 3.6e6 joules, per second => 450 MW

For comparison, the UK power grid runs at about 30-40GW.

Ok, this is a good point. But, the author just point out the quirks of JS language, and not things about the RN itself. Would be more fair if he pointed out the quirks in python or had focused on the RN. All he says about JS is very well known and is there since 90s.
Also, he is saying that its not safe because he can't understand and workaround with the pitfalls, JS has a lot of problems, but also has a LOT of great solutions for them, and by that this not means that the language is not safe, just means that its harder to work with.

With the ~3 times of thrust from the Raptor engines, do you think they will move to a "Falcon-3" design with 3 Raptor engines?

Because that would decrease the redundancy, right?
With Falcon-9 you would lose 2/9 of thrust if you turn off the mirrored engine in the best case.
In a Falcon-3 scenario, you would lose at least 1/3 for middle engine failure or 2/3 for a side engine failure.
I have a couple of DIP packages lying around, probably new. Unsure what you mean by support equipment though?

But when you're applying to an accelerator, the product you're selling is your team. You're an integral part of that team, and you need to show the YC folks what they're getting with you as part of that team.

YC seems to be trying to address the gender gap in startup founding, so I don't think that being female will put you at a disadvantage. And there are plenty of other foreign founders of successful startups.

Try to relax, speak slowly and as clearly as you can, and record as many takes as you need to feel confident that you can be understood. You'll be fine.

Economics rather strongly deprecates both history and philosophy, often offering only a brief overview of the former and a highly digested form of the latter.

One windfall of the World Wide Web are the fundamental texts now online. Many legally, through the Internet Archive, or various libraries -- the Online Library of Liberty and Mises.org, as much as I disagree with their ideological bases, have quite good collections. More in the form of illicit copies. LibGen, BookXX.org, and Sci-Hub offer access to many books and articles. Wikipedia is strong in economics, in particular offering biographies of many particular authors and theorists.

Worldcat (https://www.worldcat.org/) will help you track down published books at libraries worldwide.

Having studied economics at Uni, I'm making up for many deficiencies of my curriculum.

Well, technically, the SPDY technology (now HTTP/2) allow to multiplex connections flow, So SPDY will make faster requests on web browsing concern.

Plus, other VPN technologies (OpenVPN/PPTP/L2TP) got heavier headers, which takes more bandwidth.

How much bandwidth you got? With 150mbps Fiber, we were maxing out the bandwidth with Tunnello (120mbps+), but OpenVPN was struggling between 20-30mbps with more latency on the same server and line.

You can test it by yourself, we’d love to get a feedback if you could try both on the same country.

If you work for a big company then you may already be a member of a Facebook "network" of company employees based on email addresses. (I was joined to one.) Seems to work in much the same way as college addresses.

I've also seen company employees start their own closed, private Facebook groups for work purposes because the in-house services were terrible. (I was joined to one.) It's easier than getting a group of people to sign up for a separate third-party service. (Tried that. Didn't work.)

I assume Facebook noticed this phenomenon and decided to improve on it, and exploit it.

I don't expect most users see a problem because they already trust Facebook with their personal information. And I wouldn't be surprised if users trust it more than Google, which now stands for surveillance-based advertising.

And on Linux, the FHS does kind of suck: there's no difference between /lib and /usr/lib, or /share and /usr/share, because we don't have a separation between OS userland and external userland, /sbin is rarely used for its intended purpose, and /opt is just weird. Honestly, you should just kill most of the cruft, symlink /<whatever>
to /usr/<whatever> or vice versa, so we only have one of all of them, and leave /usr/local as it is, because we need it for software installed outside the package manager.

Actually the only thing I find positive about Plan9 is that it gave birth to Inferno and Limbo, both of which don't have much to do with UNIX philosophy.

Those that worship Plan 9 as the UNIX culture, should actually be aware what the authors think about UNIX.

"I didn't use Unix at all, really, from about 1990 until 2002, when I joined Google. (I worked entirely on Plan 9, which I still believe does a pretty good job of solving those fundamental problems.) I was surprised when I came back to Unix how many of even the little things that were annoying in 1990 continue to annoy today. In 1975, when the argument vector had to live in a 512-byte-block, the 6th Edition system would often complain, 'arg list too long'. But today, when machines have gigabytes of memory, I still see that silly message far too often. The argument list is now limited somewhere north of 100K on the Linux machines I use at work, but come on people, dynamic memory allocation is a done deal!

I started keeping a list of these annoyances but it got too long and depressing so I just learned to live with them again. We really are using a 1970s era operating system well past its sell-by date. We get a lot done, and we have fun, but let's face it, the fundamental design of Unix is older than many of the readers of Slashdot, while lots of different, great ideas about computing and networks have been developed in the last 30 years. Using Unix is the computing equivalent of listening only to music by David Cassidy. "

Ambient, that's what music critics call new age that they like. Or perhaps the other way around: new age is something they attach to ambient that's not perceived as being serious or authentic enough. Either doesn't imply much more than "instrumental" as far as I can see.

I haven't seen much of that, but I do observe that for instance this article gets lyrical about its supposed effect on their neurochemistry, which is even more ridiculous.

They have said many times the F9 lands itself completely autonomously, because when it's happening on Mars the signal delay will be too great for them to do anything from Earth anyway.

Given that, I'm going to take the leap and say the whole thing will be autonomous. I also think it makes sense so you don't need trained "pilots". You can pack the thing with 100 people that have no clue.

In the Bangladesh central bank case, hackers broken into their internal networks, got access to payment credentials, and issued $950 million worth of transactions.

$850 million was blocked before they went through, and about $40 million of the remaining has since been recovered.

How would a blockchain have helped in preventing or recovering from this attack? If the hackers got access to their blockchain credentials, they would have been able to issue similar transactions. It would just have been much harder to block the transactions or reverse and recover them after the fact. It seems to me that running this on a blockchain would have made things worse, not better.
