Anki is not a substitute for a class or a textbook.

Its power comes from using it with those tools. I always struggle to memorize a word or kanji if the first time I see a word or kanji is in the program. It just isn't the right tool for that. But when I make cram decks for whatever chapter I'm studying at the moment, it becomes extremely easy to memorize that information.

In college I always did ok my vocabulary and kanji test but I was always spending hours doing it and it wasn't fun. When I got higher up and setup Anki to review only words from the current chapter I never really had to worry anymore about my quizzes because the information was already in my head. My scores consistently stayed high on those quizzes ever since. Once the current chapter was over I would add the information to the much larger deck of what I've studied already and exam season wasn't bad either because I never had a chance to forget any words.

Vaccines and certain other medical supplies are very sensitive to temperature variations and storage conditions. I've had some modest earlier experience with medical refrigerated storage systems, and a key requirement is maintaining the specified temperature.

Propane refrigerators are an option and are found fairly frequently in environments where a consistent and uninterrupted electricity supply is difficult to maintain, particularly in RVs and boats, also in remote cabins.

Electrically powered refrigerators are generally more powerful, however, and if you can use some of the cooling capacity to create a thermal storage (or sink) mass in the form of ice to survive power interruptions, that might prove more useful.

Clickbait headline definitely overstates the case. Site should be penalized for that.
The author insists on this, and I guess it is true that this notion is promoted by popular culture. But to me it just seems insane. Have these people ever seen a swan? I mean, whenever I get close to one it is readily apparent that I am dealing with some outgrown aggressive river-beast. The only thing keeping it from biting my head off would seem to be a couple factors of two missing in the volume, which a few thousand years of evolution might have an easy solution to. I see very little cute in swans...
Which would be fine if I only ever used "+" with literals. But normally, I write things like

x + y

where x and y are values I got from who knows where. Javascript shouldn't pretend to figure out what I mean by this, because in many cases, I'm talking gibberish, and all I have is a bug.

I'd rather not talk about this stuff in terms of "types." It's about assertions, and Python makes them early and throws the exceptions early. It's a defensive practice that you can emulate in any language, and your assertions can be much richer than anything that is typically thought of as a type.
Stack Exchange owns the question & answer niche? I don't hardly think so. Yahoo Answers, as bad as it is, is massive, and shows up throughout Google's top results; ditto answers.com; and Quora is a top 500 site.

Stack has seven sites getting at least 100,000 visits per day. One is a break out homerun (Stack Overflow obviously), and it drastically dwarfs the other sites. All but a few of their top 20+ sites are strictly technology focused, and the others are geek friendly (math and video games), so they cross over conveniently.

Most of their network is flailing. Photography is 3 years old and gets a whopping seven questions per day - that's what most of their network looks like.

Stack doesn't even remotely own the Q&A category. They own one piece of it, and will never own anything more than that, because they can't translate success in technical Q&A to other categories well. You can beat StackExchange at any given of their smaller niche sites, because they can't do them as well as someone that is dedicated to just that niche - the same reason Quora et al can't compete with Stack Overflow.
Thanks for the input. Point well taken. Still, I feel like a group of curious/hacker-like folks may be able to find a baseline appreciation.

Advice for young guys/gals in building a semi-successful online service
There is lots of advice on how to get funded and build giant businesses. But what about people who want to start small. Say make a few thousand a month on a app they've built. How do we go about doing the little things to get to those first few dollars? I find that it's extremely hard.
Can somebody who has a "grandfathered" account shed light on what makes an account "grandfathered" in this sense, and also what size allocations they're giving out?

(I'm aware what grandfathering is in a general sense, but unless they mean "we're releasing IPv6 as a beta to all users who were users before we made this announcement", it doesn't seem to fit here. And that would be strange)

I understand that you're using "not like you" in the context of what language they speak, but it seems pretty clear that the author is referring to "the way that we use social networks".

Yeah, the implementation is literally just a token-by-token transliteration into Rust, just hoping that LLVM makes it go fast (and it does go pretty fast, e.g. it's faster than bff4[1], which Esolangs[2] touts as the fastest interpreter). The Rust output & optimised IR clearly show there's room for improvement, though.

I am a former Archive employee. I can't speak to their current infrastructure (though more of it is open source now - http://archive-access.sourceforge.net/projects/wayback/ ), but as far as the wayback machine, there was no SQL database anywhere in it. For the purposes of making the wayback machine go:

- Archived data was in ARC file format (predecessor to http://en.wikipedia.org/wiki/Web_ARChive) which is essentially a concatenation of seperately gzipped records. That is, you can seek to a particular offset and start decompressing a record. Thus you could get at any archived web page with a triple (server, filename, file-offset) Thus it was spread across a lot of commodity grade machines.

- An sorted index of all the content was built that would let you lookup (url) and give you a list of times or (url, time) to (filename, file-offset). It was implemented by building a sorted text file (first sorted on the url, second on the time) and sharded across many machines by simply splitting it into N roughly equal sizes. Binary search across a sorted text file is surprisingly fast -- in part because the first few points you look at in the file remain cached in RAM, since you hit them frequently.

- (Here's where I'm a little rusty) The web frontend would get a request, query the appropriate index machine. Then it would use a little mechanism (network broadcast maybe?) to find out what server that (unique) filename was on, then it would request the particular record from that server.

(Edit: FYI, my knowledge is 5 years old now. I know they've done some things to keep the index more current than they did back then.)

At the very least, I'd think about getting your blobs out of MySQL and putting them in the filesystem. Filesystems are good at this stuff. You can certainly do something as simple as a SHA-1 hash of the content as the filename, and then depending on your filesystem's performance characteristics, you can have a couple levels in the tree you store them in. e.g. da39a3ee5e6b4b0d3255bfef95601890afd80709 goes into the directory da/39/ Then you stick da39a3ee5e6b4b0d3255bfef95601890afd80709 into the 'pointer' field in your table that replaces the actual data. Obviously this design assumes the content of _that_ file doesn't change. If you want to change the data for that row in the table, you have to write a new file in the filesystem and update the 'pointer'.
I think some people find the apparent gaming of Google unethical. They seem to expose the content to Google but hide it from people who click through.

That might not be what's happening. It does give that impression though.
Which is why I said, "implemented something like this" I didn't say implement this. I meant same idea, but done in a more Google way.
Modern cheap or free static hosting providers
Hey.
I certainly don't want to ruin that article for you. For me (German, haven't left the country except for random vacations to France, NL, CH, IT or something and a year in IL) that was well-known. I've been in the UK once, in London, for two days. Guess that's a matter of which trivia based games you play or something.. ;-)

Michigan: No idea about that, that WAS news to me. But the article is about "Why don't we eat swans" and the Michigan part is really a bad example. So ... it's a pest? No hunting season though? And no explanation?

Frankly, I like swans. I regularly met and fed a couple of swans in Cologne in Germany here, checking on the young ones if the season was right.

I'd love to eat them though.

The article, for me at least, fails to deliver at least a hint of an answer to the question it proposed. That's just a bad format for me. If your main subject is a question, you need to at least try to answer it (and "yeah, they might be cute" isn't it).
Very interesting move. I love the concept of Quora and used to lose many hours going "Quora surfing." But as I fine-tuned the categories I followed, I found the fun of surfing random topics less enjoyable as my homepage feed filled with the same ole' topics and content.

Recently, I've begun an experiment to see if answering questions within my domain can help with "personal branding." It seems to have netted me a few new followers on Quora and Twitter, but I haven't noticed a substantial benefit yet.

I also started using it as inspiration for blog posts, though I'm blogging on my own site and not on Quora (not sure what's in it for me to blog on Quora). In the past, I've seen other blogs (e.g. TechCrunch) use Quora posts as the basis for articles too.

In terms of the "is Quora a vitamin or pain killer" question, it's very much a vitamin for me. Stack Exchange is a much better community for getting specific technical answers, which are the most common kinds of questions I hunt for on the web. I tend to ask my personal network for business & marketing questions, since it's difficult to explain my specific situation in a Quora question. (Being too specific sometimes runs the risk of no answers; being too general sometimes runs the risk of unhelpful answers, I've found.)

I would suspect this is the foundation for a pivot too. The advice from the YC partners and alumni network could be pretty helpful.

So best of luck to whatever they are going to pivot into!

DO has a history of doing this; see Allow Custom Images [0], with over a year of no comment, and Give option to use the Droplet's own bootloader [1], with 14 months of no comments; not even a "we're working on this". The latter shows DO's utter lack of technical competence; if they cannot even properly prepare a system image [2] or actually use their virtualization platform, what the hell can they do?

I am actually interested in IPv6 - will you release 1 IP per Droplet? Do they cost similar to IPv4 for hosting company, they are cheaper or are they free?
I actually like Quora's answers typically, but I always forget the share 'trick' to removing the blur, despite seeing it here numerous times. I won't actively use Quora because of the blur, I simply disagree with that tactic (and I think they're cheating when it comes to SEO (by presenting a different experience to visitors than they do Google's bots), and that Google is choosing not to punish it).
There was also an interesting link about why we should consider eating invasive (non-native) species. Personally I think the Canadian Geese around Oracle HQ in Redwood City could use a good thinning.

What if reproducibility is more important than uptime?

How does memory fragmentation affect performance after more than 24 hours?

What happens when your server has to restart from a cold cache scenario?

What happens when your server is down?

What about that setting that a sys admin manually applied to the server 6 months ago to fix some issue and isn't in saved in the server config?

By forcing a condition people try to avoid you get good at dealing with those situations.

How often do your database servers actually fail over?

How confident are you in your code and systems to actually fail over properly?

How do you prime the caches when your memcached servers reboot?
The article quotes an opinion saying they are delicious:

> So, tell me, what's your alternative energy supply budget look like?

http://www-formal.stanford.edu/jmc/progress/cohen.html

4 Billion years worth of Uranium on earth. And there's 4 times as much thorium. So 20 billion years then.

We're using about 3 times as much energy per year as when the paper was written, but then again we've found more uranium since then. Even if you want to cut the number in half to account for those that's still 10 billion years - cut it by 10 if you like, for energy usage increase, and that's still 1 billion years.

It doesn't matter what adjustment factors you want to use (more energy usage, more uranium found), we aren't going to ever run out.

> Additionally, how do you account for: climate change, sea level rise, phosphorus depletion, topsoil loss?

Climate change and sea level rise are non issues since nuclear power will be widespread before those things cause any problems. Phosphorus is never actually depleted - it just gets moved from one place to another, it's not possible to actually use it up. If it gets expensive (note: expensive, not rare) it will be profitable to mine it from sewage and the mouths of rivers (which is where it goes).

Same for topsoil, the nutrients that make it good don't get used up, they just get moved into plants. Eat the plant, then put it back.

> Aviation fuel is about 13% of total US petroleum consumption.

I said energy consumption, only 1/3 of which is oil. Don't forget we can make aviation fuel from energy plus air (or preferably some coal and water). And we have a LOT of coal, if we stopped using it for energy and instead made it a feedstock for carbon in aviation hydrocarbons we'll never run out.

Better would be to get carbon from plant waste, hulls, straw, etc. Remove the carbon and make fuel, remove the potassium and make fertilizer. All you need is energy to make this work.

A similar thing can be achieved in Haskell, with the Typeable typeclass. The Scrap Your Boilerplate also fixes problems like this.

There has to be some use for dynamic typing when even Haskell (ghc) adds support for it, I guess.
Fair points. Quora though seems pretty well aimed at the same subcategories which Stack Exchange excels.
This:

I think tabbed browsing gets out of control when users don’t have good bookmarking systems. I have friends who end up with 50 tabs open at a time. They want to return to a given page at some later date, but don’t have a good method of saving those for later or remembering to return. On mobile, that’s solved reasonably well with apps like Instapaper and Pocket. But on desktop, that problem doesn’t seem to be solved. Bookmarking systems can feel to heavy or permanent. And if you have been around a while, you know bookmarking apps tend to come and go (ie Delicious and Kippt).

Tabs (and I love them) are a poor solution to the horrible state-management challenge of browsers.

What I want is to maintain a list of current references, preferably with some spatial context (tree-mode browsing is great for this) to what the relationship is between pages in my browser session.

What I do not need is for every last single page to be open at the same time, sucking down memory, CPU cycles, and worse: playing videos and/or making noise.

That state-management is missing. Bookmarks aren't really it -- they're a quick-reference to stuff you want to go back to, and as with any storage locker or closet, suffer from the clean-out problem: it's a goddamned pain in the ass to go and sort through the stuff you've tossed in there and clean out the junk.

Browser history isn't it either: it's too comprehensive, is insufficiently contextualized, doesn't record context (other than, maybe, relative time). On mobile devices it's a chore to sort out where in your history a given page was. Site-supplied titles are often absolutely worthless for finding content (though as I glance up at my browser's window title I see that HN is actually pretty good for this).

There's a space between the comprehensive listing of everything you've visited, and the highly organized catalog, that's missing in the browser space. Effectively: the current workspace, with the papers and books with which you're currently working open in front of you.

I've been playing with this stuff for decades and it's still a frustration.
