Is it a rule, though? I hope not. I'm a 40-year-old generalist, and so far I haven't had problems finding work. Sure, I'm not going to get a half-mil offer from anyone, but that was never the case at any age.
ZFS uses lot of RAM only if you enable deduplication (and once you enable it, you cannot disable it). Without it, the RAM and CPU time requirements are very modest.
The productive asset IS accounted for in the income/revenue... surely?

If it is not producing revue then it is clearly not productive.
Very interesting, I had upvoted this. But this isn't something that should be tagged as "Show HN".
When we talk about relatively small amounts of RAM its not telling a lot how much RAM the device has but rather how much RAM is devoted to ZFS. Because an Android device on 1 GB RAM is a completely different beast than a FreeNAS devoted to serving files running 1 GB RAM. The same is true for 512 MB, 2 GB, etc.

PS: And was it ECC RAM?
I would guess they were trying to gauge interest so they would know how much to ramp up manufacturing.
But the question was about using Bitcoin to back something else. What's the "something else"? It's not Bitcoin. Is it something proprietary? dxhdr (whose post triggered this conversation) doesn't say, but it would almost certainly be more proprietary than Bitcoin.

Why "almost certainly more proprietary than Bitcoin"? Because somebody's using their bitcoin to back something else. That "somebody" creates (and therefore to some degree controls) that "something else".

At that point, CyberDildonics' question isn't loaded. It's a perfectly reasonable question in response to the proposed idea.

And, after all this back and forth, the question remains: Why would I want to use something backed by Bitcoin, when I could just use Bitcoin?
3 Cryptocurrency Crowdsales Giving Away Free Tokens
As a lifetime guitar player and owner of way too many, I think what I've seen (and keep in mind this is only anecdotal) is that boutique guitar makers are making a big comeback while traditional mass producers are seeing less interest. If I'm going to spend $2500-7500 on a top of the line guitar (that is often an art piece as well) I'd rather work with a craft builder and get something unique to my specs versus a mass produced Fender strat or Gibson Les Paul.
My personal answer to "how many guitars do you need?" is basically one for each tuning that I use regularly. Unless it's simply changing one string from E to D, re-tuning a whole guitar is a pain in the ass and just being able to swap guitars is a lot nicer. I have one for standard tuning, one tuned like a cello, and one in open D-minor.

I do admit if you're playing a bass guitar this rule isn't as applicable.
I think there are 3 reasons why the guitar is "dying" as the instrument of choice:

1. The explosion in popularity of EDM in the mid 00's to early 10's, and the prevalence of EDM elements now dominating pop music rather than the notion of a backing band; most pop bands now feature a guitarist, but the guitar is secondary to synths and samples if it is heard at all.

2. The rise of hip-hop, mixtape culture online, and hip-hop focused rock music in the 90's and early 00's, shifted popular rock music and the cultural zeitgeist away from a focus on guitar-driven rock music. Once again samples and synths became the focus, even in punk music. This lead to a new focus: "indie" rock and the internet could make anyone with a laptop famous.

3. The general decline in rock music quality. I might be alone in this opinion, but popular rock music in the early 00's to today remains bland and the guitar equally so. This era also saw the rebirth of hardcore and more extreme forms of metal where the guitar remains the focus, and creativity abounds, but out of the public eye.
Instead of having an "observer" process that updates a table with the LSN you can just ask Postgres directly: The `pg_stat_replication` view has the last LSN replayed on each replica available: https://www.postgresql.org/docs/10/static/monitoring-stats.h...

Also, instead of updating the `users` table with the LSN of the commit - which creates extra write load - why not store it in the session cookie, then you can route based on that.

Another option is to enable synchronous replication for transactions that need to be visible on all replicas: https://www.postgresql.org/docs/10/static/warm-standby.html#...

Since this can be enabled/disabled for each transaction it's really powerful.

Would I need experience working with large scale systems to have a chance?

I am Christian and dislike /r/atheism as much as the next guy (especially when you consider how little they actually seem to understand about what they're condemning), but I think it's one hell of a stretch to equate that with hate speech. And considering there is no shortage of libertarian guys there the qualification as left-wing is dubious in the first place.

"Anti-conservative hatred" as equivalent is ridiculous on its face and whatever "misandry" the SRS guys promote should probably be understood in a context where there is no country on Earth where men are oppressed in comparison to women.

I'm not even saying any of those subs are good, but nobody in their right mind is going to equate them with people advocating genocide or "incels" advocating rape.

I think you have really deeply bought into stereotypes of unions that, to the extent any of them are applicable, are only applicable to a subset of unions uncertain fields and only because of the market conditions in those fields.

And, on top of that, fail to recognize that some problems are inherently social, and ignoring that and failing to address them as such doesn't make them solvable by other means, it makes them nonsolvable.

Is there not an official standard / "best practices" document for what each party should follow with bug reporting / bounty procedures? Something that anyone in a company that's starting a bug bounty program can point their legal department to, and say: "here's what amazon and google and X and Y and Z follow, so we should do the same"? From the security researcher perspective, there's the responsible disclosure stuff. But not much from the other side, AFAIK.

Libertarians can be left-wing, so the premise seems irrelevant to the conclusion.
Im very confident the author knew this and thought this little shell game would make his calls for deregulation look convincing.
I think that eBay is already affecting price in a different way: buyers and sellers tend to use eBay price to figure out what a guitar is worth before buying and selling in person. Since used guitars are a risky purchase (there could be a lot of things wrong that don't show up in pictures), the eBay price is artificially depressed. However, since the eBay price is seen as the "fair market price", it deflates the price everywhere.

This could go the other way, as well: if sellers refuse to sell a certain kind of guitar on eBay, the price could become inflated.

But vim is really not that hard to use. The initial learning curve might be steep, but as a whole vim is in general easy to use once you 'grok' it.

Anyways I do agree with you on one thing, this articles convey the idea that vim requires plugins and magic to be usable, which in my opinion is a disservice. People get on the bandwagon and install 50 plugins and then complain that vim is unusable when sshing into a server because it doesn't have the plugins they use.
You should read the title as “Germany bans smart children”
There is the same ban in Russia. Where can I find full list of countries with such idiotic bans? What about UK or USA?
As mentioned above this ban can’t stop people with bad-will but make the problems for all the other people for their taxes. I can’t understand how a reasonable man can support such ban.

What is the penalty for using banned smartdevices in Germany?
Wow, people react negatively to a catchphrase of avowed racists? You can't really expect people to completely ignore context.

This is such an interesting article, attempting to answer one of the biggest questions of the 21st century in one fell swoop. However, I'm not sure all of the reasoning and analysis holds up. For example, software engineers with salaries over 390K are far from rare in the US, and Switzerland has both large numbers of bankers per capita and private doctors with incredibly high incomes.
Yeah after re-reading this thread I think I've properly gone off the deep end with this one, I've probably misread your initial comment, I think, sorry if I did.
>Forcing every prospective engineer to attend 4 years of formal computer science education isn’t a realistic answer — and ultimately it doesn’t even solve the problem. Formal comp sci education is a foundation, but the application of comp sci to problem solving is a skill that is learned by experience and mentorship.

This is the thing that has been killing me and incredibly demoralizing as I've been trying to find a position at a company, along with not having production experience in the specific frameworks that they're looking for. I've started a project from the ground-up with my bare hands that managed to make over $500,000 in crowdfunding, but because I didn't do it in a framework that modern companies want, and because my degrees are in Biology and Psychology rather than Computer Science, even when I've trained myself in the frameworks in question I'm a pariah to hiring managers.

I'm seriously beside myself now. I have no idea what avenues I even have left open to me if I want to have a career at this point. The only way I see myself getting a job is going further into debt by going through a bootcamp.
That is ridiculous. Electronic music production is a completely separate market.
Good stuff. Came into this thread expecting the top comment to be a know-it-all answer trying to "debunk" the article, as so commonly seen on HN. This is a perfect, well-researched response.

Note that's only behaving correctly if synchronous_commit is set to remote_apply, which has been added in 9.6. Before that syncrep could only guarantee that the remote side has safely received the necessary WAL, not that it has been applied.

But don’t forget, our brain is limited to some extent and won’t be able to hold that amount of information. You’ll live to a thousand years, but you’ll probably only vividly remember the last five decades, and some smatterings from the past. Is that really meaningful?

Actually I also desire for longevity for reasons like yours, but I’ve been thinking, perhaps it’s more important to measure the quality of experiences rather than number of years. Wisdom, basically - and from history, we know that a deep level of that is attainable irrespective of background and age.

And then, there is also the eventual apathy towards life and wonder. I’m most afraid of that.

It looks like this is based algorithmically on genetic ancestry. I'd like to see a deep learning model trained from facial image and genetic data to build a tool for generating faces from genes.

The high end guitars are usually pretty boring, but it's really nice to have one or two. I'd rather have a decent variety, but one or two of those can by a high quality guitar. My favorite guitar is still my 60s Norma (Teisco) with gold foil pickups. Other favorites include 80s Korean Squier with new pickups, 60s Yamaha acoustic, 60s 1444 Silvertone/Danelectro bass. A lot of the new Fender/Squier guitars are really interesting too.

I'd probably buy a nice Les Paul Jr, Tele, or Ric, and it'd probably be my main guitar, but owning 10k+ worth of Les Pauls sounds boring.
Agreed. In this case there is an implicit, very large, bug bounty that anyone can cash in. So far there has been one creation of new bitcoin bug and zero spending other people's bitcoin bugs.

That does not mean it's secure, but at this point it's looking more secure every day.
Hush! Don't speak of such things, or before you know it there will be DRM enforced IoT dongles with 4G cellular radios, requiring a subscription plan and annual fee before the guitar pick-ups will serialize their signal to a 1/4 inch patch cable.

What's your recommendation how to solve the problem described in the article? Would you compare LSNs of replicas in application logic at all?

Unfortunately, people have extremely high trust of Google. People use Google to win arguments. People use Google as a replacement for text books.

I cannot agree with this enough.

I'm a pretty capable "generalist software engineer", but what keeps me employed is expertise in virtualization and high-performance virtual networking. Prior to that, it was expertise in distributed systems and a knack for debugging distributed failures. The history here is relevant: later in the thread Thomas points out that you can switch domains. My time spent in distributed systems with multi-millisecond quorum periods is more or less directly applicable to debugging synchronization issues at CPU clock speeds. The tools used to observe the issue are different, but the reasoning process for untangling the set of plausible partial orderings is the same.

Did you know you can buy a $350 "Gibson Les Paul" that says "made in the USA" on AliExpress? The guitar in question is CNC cut and then hand assembled. I may speak from experience when I say the item is very high quality and is a pretty danged good guitar.

The point here being that it's an industry what are the American players have not modernized their manufacturing process... We live in an amazing age where you can own an extraordinary instrument for very little money.
I have, regrettably, invested in just about every Kickstarter, Indegogo, and CES vaporware to bring a fully wearable lifeblogging camera to fruition. ZionEyez still smarts...

Ever since I read Daemon by Daniel Suarez, and more importantly, the Halting State series by Charles Stross, I've wanted this ability. We have two pairs of Google Glass and I keep them on a bookshelf, as a reminder of how close we've come to this reality.

Musical instruments are one area where "services" are quite valuable. Anyone with enough time and effort could learn to play entirely on their own and maintain (or build) their own instrument, but for many people it makes sense to take lessons and to pay someone to repair or adjust their instrument as needed. This is one reason why guitar shops are at least partially protected from being driven out of business by Amazon: most have a guitar technician on staff who can troubleshoot problems and fix things.
For accounting you probably want to keep it simple. Accounting should be a baseline sanity check to keep numbers somewhat in line with reality. It's not meant as a valuation model.
*> business ownership, which is much more rare.

First, you're assuming that all these "professionals" are not also business owners, which is often false; doctors and lawyers earning enough to put them in the top 1% are most likely owners of or partners in a private practice.

Second, if we restrict "business ownership" to those who are not "professionals", the fact that it is rare is a consequence of regulation, not an independent fact. Regulatory barriers don't just benefit "professionals" who have the requisite qualifications; they also hamstring people trying to start businesses not in those particular "professional" sectors.

So the result is only "not surprising" if you take the level of regulation we have now for granted.

My dad loves to tell a story about a Q&A session with Norm Abram of PBS [Edit: This Old House, New Yankee Workshop] fame, which your answer reminds me of. Why does Norm own an entire drawer full of routers?

Well, he used to ask himself the same question. All these companies kept giving him free tools as a promotion. Especially routers. He had dozens of them. WTF do I need all these routers for?

It occurred to him that if at the start of a project you put a bit into a router and don't touch it until the end of the project, all of your routed edges will match exactly. Even if you screw up and have to redo a piece. So he kept enough routers to do that. He still gets teased about it by his coworkers though.
