"After the DNS resolves the IP will be cached by the client for hours"

Not true because my TTL is low (5 min). Chrome will even try another IP within tens of seconds if the initial IP becomes unresponsive. I tested this on Linux. That said I recognize this is not a production-quality mechanism to implement HA (large sites or CDN providers use anycast, load balancers, etc.) But for a personal blog, this is perfectly fine :)
As an aside, in terms of design and little helpers (e.g. git/virtualenv) powerline shell really made my terminal much more friendly: https://github.com/banga/powerline-shell

Idea: proper graphics for data/image/video display.

I think it's an interesting idea that a terminal editor can have text only input, but the ability to draw real high-res graphical output. e.g. a canvas to draw your matplotlib diagram in the terminal output or a more graphical version of htop (with time data graphs etc).

LabVIEW is pretty mainstream in scientific instrument construction and control. I just wish more HN type people were exposed to it, because a well designed graphical language is unquestionably more productive than a classical programming language, at least in that problem space.

In my experience TTL isn't respected at all. Clients will cache IP addresses no matter what.
Interesting to ponder. I'm working on an app for podcast discovery (think Youtube for podcasts; I've put the twitter link in my HN profile page if anyone is interested in updates) and I've been thinking about this. I am generally anti-curation in my current approach. In this context I don't like the concept of people asking you to upvote something on Product Hunt, or leave a review on iTunes so it filters to the top of the list and gets some editor's attention, etc. I kinda prefer the Netflix or Youtube approach that tries to figure out what you'd like based on your viewing history, or items related to what you're viewing, or what other people who like what you're viewing have also liked... (Related, I also don't like the idea of 'categories' where you have to select whether an item is 'History' or 'Politics'. I'd like my software to be able to group items intelligently without manual intervention...)

So in a way, with something like the way Netflix replaced explicit star-ratings based recommendations with viewing-history based recommendations, we are still looking for curation but in a subtler, more algorithmic way... same with Google PageRank and Facebook Newsfeed for that matter. Maybe algorithmic filtering is just curation at scale.
I wonder how this will affect the cattle's mating. Cattle don't do missionary; I wouldn't be surprised if eye contact totally kills the mood for a bull.
Amusing that he views something with a predicted chance of occurring at 25% actually occurring as a market failure.

He may be right that prediction markets are currently experiencing an anchoring effect that is slowing their response to changes in the factors that influence the outcome. If you believe this, maybe you should go buy Trump shares in various prediction markets. Personally I think that a long position on AAPL is a better undervalued position than Trump for President.
IMHO there are certain tasks where the rule is more applicable, and others were it isn't. I think music and athleticism involve flow states and muscle memory, whereas math and writing tend to be more cognitively demanding and involve more structure and rules, and you either have the talent to do well or you don't, and such talent tends to manifest at a very early age. The 10000 hours is the amount of practice that allows an already talented person to possibly compete at the world-class.
People take the 10,000 hours "rule" entirely too seriously.

Gladwell himself admits 10,000 hours is rather arbitrary. The point is still important though, as far too many people start a new skill and are disheartened by their lack of ability before putting in serious practice.

It might seem obvious that practice is necessary for most skills, but people forget it all the time. For example, when I'm teaching people programming they're quick to think themselves failures when they see the giant gap between their abilities and my own. What they don't realize is that I've been doing it for over a decade and, in fact, was much worse than them at first. [0]

[0] In fact, I probably only did HTML for my first whole month of "programming." One major advantage of learning things as a kid is that there's no pressure to be good.
Indeed I find of their two examples the "consonant harmony" is a bit dull and the "dissonant harmony" sounds like it might be from something more interesting like the Große Fuge, one of my favourites and probably more dissonant than their example.

How do I report a bug in an app?

The email app Roundcube does not seem to support unicode characters in the senders name in received emails.

I don't want to get in a debate about what a hedge fund is, but while the term "Hedging" is the practice of reducing risk, the goal of most hedge funds is to maximize ROI. The term hedge fund comes from the historical tendency of the first "hedge funds" to hedge against the downside risk of the market by shorting the market (as where mutual funds can not usually take a short positions). In today's terms, hedge funds employee many different investment strategies so it isn't accurate to say hedge funds just hedge risk. Hedge fund managers usually make speculative investments and can sometimes carry more risk.

The funds is bench marked to Credit Suisee HF Index, Citibank Prime +5%, S&P 500. It is beating the bench mark since inception and that historical statement is verified by our auditors. Your point regarding "attracting huge amounts of capital" holds true when a fund reaches a certain size, typically greater than $120M, getting to that point is where a lot of the work happens. The point from start to autonomous growth must be managed with extreme care and diligence, it is imperative that a growing fund manages their growth to not try and grow faster than their operations can support. -- Which is what I'm asking HN, I am soliciting opinions and experiences from smart people, maybe growth hack is the wrong term.

I agree that as a fund grows it definitely gets harder to scale, and at this time, we haven't begun to scale at our full potential, so that point remains in the central view of the risk committee.

Thank you for contributing your opinions.

Your link explicitly says you're wrong, though. Read it. It says:

> My life would be a heck of a lot easier if per-application settings were stored in a place I could easily see them, manipulate them, and back them up. Like, say... in INI files.

> The registry is opaque and binary. As much as I dislike the angle bracket tax, at least XML config files are reasonably human-readable, and they allow as many comments as you see fit.

Now look at the comment you replied to:

> Just because Windows' registry is hard to manually edit doesn't mean they are a bad idea.

You said that's not the problem with the registry, but your own link says that's exactly the problem with the registry...
The HA part looks pretty cool!

I'm not a big fan of the design though. I find the visual hierarchy of the layout a bit confusing:

- There isn't enough whitespace around the content, making it feel cramped

- Scrolling isn't a bad thing. I usually find a top-down flow (from title to content) easier to navigate than reading down from the title to the byline and date, then back up for the content

- Comments and comment form below the content makes sense since people usually like to read and post comments after they've read the blog post. Having them at the top forces users to scroll up again.
This is something I wish more effort was being put into. As more and more apps become V8-based, with each shipping completely separated, I wish there was some way to have them share resources. I know there are a lot of issues with this (different Node versions, possibly security, and figuring out inter-app resource sharing), but it would be magnificent for my computer's battery life. Does anyone know of any work being done on this front or a possible implementation?
That's insane. For less than a months payment someone could of thrashed the car.
I've definitely seen counterexamples to this, regarding drawing. Some people are visual thinkers, and some, despite thousands of hours of attempts, aren't.

There is such a thing as innate talent. Do you think anyone can be a world class physicist or mathematician with 10,000 hours practice? What about sprinters, programmers or entrepreneurs? I certainly don't. Not any of the above. I think people who achieve a high level of performance have almost certainly put in a lot of practice, but the reason they keep practicing is they have some natural aptitude for what they're practicing.

Gladwell's myth is comforting to our present elites who claim to have gotten where they are via hard work, and keeps the peace with the rubes.
Nope, it's "hurtig".
After all, a message that gives hope to the dullards who buy his books that they too can covet the skills of geniuses with just enough practice, is an appealing one.

Maybe having eyespots in weird places would deter potential mates? That would be a pretty powerful evolutionary incentive to just not have something that weird back there.
I just use hugo for site generation, isso for self hosted comments, rsync for dumping files on the server and postcss for all the styling. All the scripts are in a package.json so I can download and run everything with an npm run build-init. I don't think most people's personal blogs need to worry about high availability, multiple servers and the complexity that goes along with it, but I'm sure some do. I simply don't have that traffic.

The orange line is neat, I opted for a css avatar replace as isso tags the generated avatars with an id I can grab. The two columns I'd have to get used to, maybe I'm just easily distracted.

Thanks for posting this.
Destroy All Ifs – A Perspective from Functional Programming
I wonder what value such curation has in today's terms, even if it were for a niche category. Plus, how does a modern 'surfer' know what they don't know (a site that should be included but they haven't come across it yet)?

Also, I wouldn't imagine there to be any sort of IP to such an idea, as the sites listed belong to other people/companies.
Well yes, but I don't think people even realise that there are actually representatives from the UK there who don't do nothing.

There was a Scottish MEP who made an impassioned speech in contrast to Farage's nonsense. a) I only saw it due to it showing up in my relatively pro-EU Facebook echo chamber; b) I'd never heard of him before.

That sounds absolutely horrendous, and there's no good reason why they had to be like that. It's unreasonable to assume all visual programming languages do things the same or a similar way.
OK, we've updated the submission from the article's document title “Why So Many Bog Bodies Show Signs of Violent Death”, to this.
How do you take a server out of rotation if one goes down? For example, if I hit a server in the round robin that isn't online, I could try force-refresh the page to initiate a new lookup but in that case 1 in every 3 requests to the site would still fail (assuming only one server is down, and hoping my client doesn't decide to cache the initial resolution?). In your post you mentioned a browser can handle this transparently - did you mean that if the client can see that the domain has multiple A records and the initial connection fails on one of the IPs, it will automatically try to establish a connection on the next IP in the round robin if the first connection times out, is that correct? Is this a browser standard or is this behaviour handled differently between different browsers?

Either way interesting project, thanks for sharing.

EDIT: Also it'd be cool if the code wasn't in a tarball. I'm on a mobile device (as I'm sure many of your users are too) that doesn't allow me to save/extract the archive. Would've liked to have had a browse through it! Maybe consider uploading to a service like GitHub, or having an extracted version available so we can view the contents directly in a browser? :)
We agree on the metabolic reasoning! I freely admit that 98% of my experience with diabetes has been in the field dealing with hypo or hyperglycemic patients. Obviously, we are talking about diabetics that aren't the most compliant with their disease. However, even "good" diabetics have bad runs with questionable supplies, or any host of issues (sickness, environment, diet change, etc.)

I happen to live where a very, very large cluster of diabetics are studied. We do a lot of diabetic emergencies... I can count on my hands how many times we've used glucagon. Like I said, we can treat and release with D50. Not so with Glucagon.

If "they" figure out the delicate balance between all the systems in order to use glucagon the same way it is regulated in a non-diabetic; it stands to reason that "they" should have a way to repair/replace the islets of Langerhans as the first priority, don't you think?

But "traditional" quarter-tone music typically does not use much harmonics, right?

I think you need to practice to appreciate music - some people get just stressed by listening to a complex Bach fugue, and some get equally stressed when listening to rap music or traditional jazz. Probably because they do not pick up the nuances.
Distinct mistakes. If there were only one mistake you could make, it would then be unique.

An RRSP in and of itself is not a fund type. Similarly to a 401K it is an account which holds investment positions (e.g. Mutual funds, ETFs, single-stock positions).

As for 'growth hacking', that's really not a mindset I would recommend for any investment strategy. First, think of the asset class (real-estate), the investment strategy and the securities/investment products involved: can you scale them up and be as profitable? If you can demonstrate that you can, then growing the AuM shouldn't be too hard. 'Growth hacking' sounds like smoke and mirrors - I wouldn't recommend that terminology with investors.
You missed the next one:

>consisting of or combining two or more separable aspects or qualities.

I recommend the Wikipedia article [0] as well. Here is a snippet:

>A portmanteau (Listeni/pɔːrtˈmæntoʊ/, /ˌpɔːrtmænˈtoʊ/; plural portmanteaus or portmanteaux /-ˈtoʊz/) or portmanteau word is a linguistic blend of words,[1] in which parts of multiple words, or their phones (sounds), and their meanings are combined into a new word.[1][2][3] The word "portmanteau" comes from the French for overcoat stand (porte manteau), where many coats may be placed on top of coats that are already on the stand, which continues to function as a coat stand.

>A portmanteau word fuses both the sounds and the meanings of its components, as in smog, coined by blending smoke and fog,[2][4] or motel, from motor and hotel.[5] In linguistics, a portmanteau is defined as a single morph that represents two or more morphemes.[6][7][8][9]

Could you help us understand what the limiting factor in these simulations are?

By memory considerations alone, a N-qubit wavefunction (using 64-bit floats) uses 2^(N+4) bytes, and a N-qubit unitary operator uses 2^(2N+4) bytes. If you use 1 GB of RAM, that allows you to store full unitary operators up to 13 qubits.

If you use sparse operators to store the gates (which have a size in memory that is a constant times the wavefunction size) you can imagine doing 24 qubits.

Of course fighting exponential scaling is always hard, but I'm not sure if I understand why the limit (for a hobby-level project) is closer to 10 than 24.
I tested this pretty extensively. When I switched IPs, 99.9% of the HTTP traffic hit the new servers within the TTL time (5min). The only residual traffic hitting the old IPs I saw was from poorly configured bots & webspiders who probably don't re-resolve hostnames frequently enough.

I remember also reading a post from Amazon EC2 Route 53 engineers who investigated DNS propagation times across large-scale tests in the world, and my observations aligned with theirs. They concluded the "DNS doesn't propagate according to TTL" story is mostly a myth (modulo rare issues here and there).
In the Sandstorm UI, if you go to "Apps" and choose the app, you'll see a "report issue" link in the upper-right. Generally, these link to the GitHub issue tracker for the app or its Sandstorm packaging.
That was my mistake. I meant 10 pounds per square foot on an annual basis.

The minimum temperature is 50 degrees Fahrenheit, but that is a limit for the bacteria, not the fish. The maximum temperature is whatever can be found the natural bodies of water, practically speaking probably around 100 degrees Fahrenheit. Of course, it all depends on the fish you are raising.
isnt Japan missing from that list?
Agreed, that growth hacking was the wrong terminology, I think I was being to aggressive with the description.

Yes, an RRSP is not a fund and like you said, a vehicle to hold an investment position. I was not trying to insinuate that an RRSP was a fund and I will edit my previous comment.
Reading a couple of the linked posts, I thought this was the best take on it from mathematician Jordan Ellenberg (it certainly made sense to my comp-sci brain):

It's not quite right to describe what the video does as “proving” that
1 + 2 + 3 + 4 + .... = -1/12. When we ask “what is the value of the
infinite sum,” we've made a mistake before we even answer! Infinite
sums don't have values until we assign them a value, and there are
different protocols for doing that. We should be asking not what IS
the value, but what should we define the value to be? There are
different protocols, each with their own strengths and weaknesses. The
protocol you learn in calculus class, involving limits, would decline
to assign any value at all to the sum in the video. A different
protocol assigns it the value -1/12. Neither answer is more correct
than the other.
I found a way to get to the github page of the app.

(Open the app in the app store and click on the '</>' icon to go to the github page of the app)

Maybe feedback and bug reporting could be built into the Sandstorm system in a user friendly way, without need for a github account, both for apps and Sandstorm itself?
To some extent you're right and I see your point, but this is also a false dichotomy. Gladwell can be whatever he wants to be. He may be rooted in science, but let's be honest, 10,000 is a fairly arbitrary number. If the world couldn't figure out that 10,000 hours wasn't scientific, we may have a larger problem.

I'm more mentally exhausted by the endlessness of pure contrarianism on the Internet. It gets worse and worse with each year and I'm losing my enjoyment of social communities.
That Yahoo took so long to give up the DMOZ directory-style mentality is just another example of technologists favoring a neatly ordered solution over an organic one. In the crowd-sourced organic model, there is less curation, and more a time-based record of fleeting curiosity.
I wonder what did they hide inside of that drawing of a matryoshka?

People say Windows' Powershell using some sort of objects rather than a text stream is good.

For me I want better control over how my shell records and stores history. I want it to record more and probably not in a flat text file. I don't want it to write commands that fail to disk but I do want them in my history so I can correct my typo and run again.

I'd like lines to be rewrapped if I change terminal dimensions. I'd like more automatic pagination (rather than forgetting to use less and nuking your scrollback). I think is an issue with mintty/putty but I'd like its command history to be printed correctly after changing the terminal width.

Pet hates: terminal bells that I didn't explicitly ask for; middle click paste; the obscure terminfo file that sometimes controls the features a program uses.

Overall, this article is actually pretty poor analysis. It tried to be analytical but doesn't actually provide compelling evidence or analysis. Instead, it just presents a 4-step strategy without causal links between the steps. Worst of all, there's no justification for why Apple would want to "create an environment for independent artist sustainability" as their end goal.

I completely disagree with Exhibit 1 (the growth chart) signaling a positive trajectory for Apple. Tellingly, it looks like the exact opposite of the Spotify chart: huge initial growth which is rapidly tapering growth. In contrast, Spotify's growth follows that of a traditional viral product: growing exponentially up and to the right.

Moreover, I don't think Apple is positioning themselves to succeed. Their software quality is near an all-time low. [0] They're doubling down on human curation while Spotify has been doing amazingly with Discover Weekly.

Just look at user reviews. On Android, Apple Music has 3.3 stars. [1] Spotify? 4.5 stars. IMO, Spotify is even able to deliver a superior product on Apple's own platform. Apple Music continues to be buggy, error-prone, and significantly less than delightful every time I try it.
