most of the inter exchange arbitrage opportunities are eaten up by the fees and because there can be a time delay across exchanges it also adds risk. The intra trading (especially in my case ) has those risks minimized. there are no fees on cex and the trades happen very fast.
There's this one link at the very bottom of the page, which the Peek user kept missing, and would be the first one I would go to if I couldn't find what I was looking for: Product/Project Page. That appears to be the page that would have answered many of his questions and kept him as a customer. That should totally be at the top of the page.

However, even that's a little confusing because it is itself a project -- so a user might wonder what the heck they are looking at, site info or some other project?
Thanks for explaining Chris.
Even if it's a cent, who cares? This is just money laundering.

Just an update on the product launch.

I've got a handful of sales coming in which is great. Mostly driven by a post on the bitcoin forum.

People there are certainly raising the trust/hacking issue. I am being open and honest with them and trying to communicate in a responsive manor. Maybe honesty, responsiveness and time will be the key.
True, but my point is that the people who have actually been working for him for many years now have no negative experiences along these lines to report that I've seen. And that if you're worried about how he'll treat people working for him, the best thing to do is to ask the people who have been working for him. It's not like he's a new hire into the organization or something; there are lots of people around who have been interacting with him for a long time.

I agree that if you had no other source of information than the existence of the donation, that would certainly raise the chances of there being problems in other aspects of interacting with the man, of course. That's obvious. I'm just saying that if there are non-proxy sources of information available, it's better to use those than to use proxy sources that rely on good but imperfect correlations. (The correlation in this case being "someone who strongly supported Proposition 8 is also a problem to work with if you're gay". Reasonably good correlation, I expect, but not perfect.)

Just to nitpick a bit, voter turnout was nowhere near 100% in 2008, so no, we can't say that 52% of Californians were toxic in 2008 (not counting LA obviously). The types of donations that went into the pro Prop 8 campaign helped fuel a marketing effort intended to stir up emotions among the anti-gay crowd. That was pretty toxic.

The idea of explicitly enshrining our collective dislike of gay people is also just pretty toxic all by itself, naturally, but that's a slightly different tack.

Would you really extend this to any opinion one might have? Suppose a large percentage of women in your state thought men were unfit to vote. Supposed they were enough to legally remove men's right to vote. Now suppose a supporter of that position was hired as your boss. Would you really be OK with that?

Feel free to picture more repugnant positions. Would you really not draw the line anywhere? If you would, then you're not really any different than people around here, you just disagree where you draw the line. And frankly, I find it very hard to believe that someone wouldn't.

I don't think it's exactly money laundering.

It's like all theft. At low enough risk, the thief doesn't care what percentage of the value (of the $ charged) they recover. In this case, they are running very large CPU (not GPU) instances on someone else's dollar, not caring about the inefficiency of it because it can be automated and is difficult if not impossible to trace.
Indeed! This makes proper research hard.

In the world, outside the bubble, there are still more people using PCs to do stuff than pretty much any other device. That looks like it's in the process of changing. But the only people who think it already has are folks living in a very particular slice of reality.
Thanks anatari for providing this feedback. You are spot on - our biggest technical challenge is to make a generic recommender that will work with a variety of different verticals. Our current approach is to limit ourselves to 3 specific verticals. For example consider the "news" vertical - a recommendation engine that works for NYTimes will likely work fine for WSJ.
Both this and the subsequent text on differential geometry are very good but they are written against this enormous undocumented scheme library (scmutils) that is in my opinion very difficult to debug or figure out how macros expand out.

I have no idea what the GP meant, but fwiw: Korean is written using an alphabet not entirely unlike Latin (for the purpose of this discussion), except that when written, several letters are layed out together in syllabic blocks.

Those blocks appear superficially similar to the characters used to write Chinese languages and much of Japanese. However these are logograms, that is each character represents a whole word (simplfying again - in truth many of these characters can be broken apart into components, but they're not assembled from phonograms like Latin or Korean characters; further, Japanese writing also uses a set of phonograms in addition to and together with the logograms).

Ultimately this means the Korean blocks are much more regular, since they're all composed from the same small repertoire of individual characters, with not even all that much complexity to kerning/ligature-like behavior, though font systems usually work with precomposed blocks instead of doing on the fly character composition anyway. Their shape complexity/stroke density is also lower. And handwriting recognition is massively simpler for all of those reasons.

That seems like more of an argument in favor of having all source code available (i.e. not using closed-source libraries) than an argument against OOP. The question of what code executes when you call `person.walk()` is no different than the question of what code executes when you call `(person :walk)`: it depends entirely on the value of `person`! This is the core of dynamic dispatch in OOP and higher-order functions in FP, they enable behavioral abstraction. You can impose restrictions on the behavior through types or contracts, but at the end of the day you can't know the precise behavior except in a specific call. And this is precisely where a live programming environment comes in handy.
As of now, it really doesn't look like a wise investment in anything Google that is not replaceable e.g. Search.

Flexibility is a feature. What requires clipboards is a lack of strength. Flexibility is what allows paper to bend and not break when you overcome its strength by flapping it around.

Designing the worst products possible
This graph of The Simpsons illustrates (for me at least) that IMDB is more reflective of the viewing community's weird quirks and biases.

Honestly: is "Homer the Smithers" the best episode of The Simpsons? I doubt anyone would truly put it on their "best ever" list. It's really more "solid" than great. Most importantly: it doesn't rub anyone the wrong way.

Is "Saddlesore Galactica" one of the worst episodes ever? No. It's extremely funny and the story is structured well. It gets lots of very low votes from viewers who favor realism over humor (the episode is implausible with the horse racing then gets silly/fantasy). The episode's score reflects a community desire rather than an objective opinion.
The people saying he failed finding the "correct" solution are underestimating the challenge in getting people to change their behaviors so radically.

of course, the same could be said for changing the font, but hey, baby steps.

ps: i don't actually agree with the font switch idea. less ink means lower readability in marginal situations (at night, after photocopying 3x, etc etc)
It's a great hack that uses lousy data. IMDB ratings are best perhaps with films, a lot less reliable with individual episode scores. Also, if a show goes south do viewers keep watching it and rating it? That phenomena alone sort of spoils the fun for me.

I think it'd be ok to sell a game engine to a game company, so long as the openness promises are maintained.

Oculus had the dev community rallied around them. They just had to create a platform and standards, sponsor the open metaverse and they'd be in a great position to make billions from portions of transactions / marketplaces / convenient ad services / etc, just like Google does with Android. Instead they sold to FB, who will no doubt pull an Apple. In an instant they destroyed the vision, and now we have to wait for the next Google to come along and prevent any one company from gaining too large a stranglehold in the mean time.
That is why AWS has billing alerts that will send you an email or text if you reach a predefined spending threshold. I had some trouble to find at first on their website so maybe it should be more visible.

The cool thing with Amazon is that they definitely pay attention to your opinion as a consumer. A few months ago, I sent an email to Jeff Bezos to complain about the Amazon Locker interface that I found cumbersome - it used to show you all lockers including the full ones and there was no way to see which ones you can actually deliver to - and his assistant answered and let me know that my message was forwarded to the appropriate team. They changed the interface a few weeks later. Maybe the author of this post should do the same.
Where do the testers for peek come from if it is free?
Right, PG calls the REDO log the WAL (for most purposes they are the same thing). I did not know that 9.4 can do partial page writes to the WAL now. Guess I will have more reading to do, thanks for pointing it out! A nice blog post by a colleague recently showing how large writes to redo logs matter is (not about PG, but why it is significant in the context of size of entries):

http://smalldatum.blogspot.com/2014/03/redo-logs-in-mongodb-...

As far as when clustering a table is useful, see the CLUSTER command in PG. It is roughly the same places you would want to do it, except it is automatically maintained. You do need to realize what is going on to minimize impact on inserts, but in a lot of cases, data in inserted in generally ascending order so it mostly 'free'. This does make GUIDs really bad for PKs in InnoDB.

Clustered indexes are like covering indexes (which PG got recently). You don't quite realize how useful they are until you get access to it ;)

InnoDB compression for us is primarily for non-lob objects, so TOAST is quite a bit different than the cross-row compression that we get. We will normally do compression of large objects outside of the DB whenever possible.

I'm not saying that InnoDB is always better than PG, but in a lot of cases that I have tested it with, it is indeed better. PG has come a long way recently, including options such as covering indexes to close the gap.
I know that it is trendy on HN to hate on Jobs now (ok, that was spiteful, sorry) but I think no-one around here has the insight to judge what Steve Jobs what in the success of Apple.

Apple grew from zero to great; Jobs lead it. This is all the correlation I feel entitled to dare, did reading the biography grant you more? (Again spiteful. Sorry. So this is how aggressive comments are written...)
Oddly: seems like this might be a place for Google to put its natural language processing skills to work. If they can figure out WTF a product, excuse me, solution page is about, you're in reasonably good hands. Maybe.
I don't know if that's the case. Perhaps Musk is enabling the media by specifically stating that these reinforcements are for preventing fires. I actually would go so far as to say that a good CEO would not do something like this because it lends credence to the media's claims about the fires - that the fires are an issue that need to be fixed, rather than some rare occurrence that would probably be worse in any other vehicle in the same wreck.

Precompiled headers are a pain to use. But clang modules are supposed to be precompiled headers done right:

http://clang.llvm.org/docs/Modules.html

When they're usable for C++, there should be little reason to use any special preprocessor, since every header file (not just a static common set) need only be compiled once into a binary format rather than being included into N source files. It can't happen any sooner for me... but as of recently, they're still very broken, so I'm still waiting.
>There is a word for it, "greenwashing".

Yes, that would be the 6th word I wrote.

>Biofuels are a perfect example in my opinion

Biofuels are an awful example because biofuels are complicated. The carbon accounting for growing bio-fuel crops vs. food crops vs. not farming, vs. managing the land for environmental purposes.... the pollution accounting by replacing petroleum with bio-fuels... the complex production costs and effects. Some biofuels are certainly better than others, but I don't think anybody with domain knowledge would propose none of them have positive impact.

Reducing fuel consumption is a separate issue from choosing the best fuel source, conflating the two isn't productive.
Agreed. I'm hoping the dude used a bigger sample than one to determine whether the design needs to change. A/B test for sure.
I like where this is going. Gitlab is a pain to setuo and is moving more towards an enterprise offering, gitorious is awful and mostly un maintained (mostly). There is lots of room for a small and nimble tool like this to come along. Good luck!
Other people in this thread have tested warp against both cpp and clang and posted numbers.

BTW, of course if a preprocessor is integrated with another program, Warp can't replace it. It can replace standalone use of a preprocessor.
There is nothing that prevents these from being implemented for PostgreSQL. In fact, they have already done a lot of optimizations that close the gap, such as covering indexes. Before covering indexes, InnoDB was even further ahead of them.

Of the ones mentioned, I would guess compression is the most complex. For InnoDB this took many years to get the point of it being usable and efficient. Many naive implementations can cause huge overheads for CPU which makes it unusable.
The permissions are too much.
Most of the large general sites I know of that break it out by visitors (not by hits, which is silly) fall in line with the Net Applications numbers. Note that these numbers will not match up with tech-focused sites or most startup and early-adopter sites (most of the sites folks that visit HN run). So, you'll get voted down any time you state it here (see my post above downvoted to 0), because, for some reason, people get really mad any time you point out how dominant IE still is.

And I say this as someone with my own large tech-focused site (over 2m visitors a month) which sees about a 40-34-17-3 split for Chrome-Firefox-IE-Opera.

There's been some progress, though, as at least we have fewer clueless people citing W3Schools' stats these days.
> I wonder what air travel would be like instead of the race-to-the-bottom experience it is now.

Comparing a niche (expensive) car manufacturer to major airlines isn't really an apt comparison. First, airliners are mass transit. Second, the airliners used to be very much nicer than they are now, it was market pressures that drove them to where they are (combined with the deregulation that was also due to people wanting to pay less).

A better comparison would be to compare Tesla to some of the General Aviation aircraft that are available. The [DA-40](http://www.diamondaircraft.com/aircraft/da40_xls/index.php) would be a reasonable starting point and could likely be afforded by the types of people who can afford a Tesla.
This quote seems apropos:

Though many object to psychiatry’s perceived encroachment into normality, we rarely hear such complaints about the rest of medicine. Few lament that nearly all of us, at some point in our lives, seek care from a physician and take all manner of medications, most without need of a prescription, for one physical ailment or another. If we can accept that it is completely normal to be medically sick, not only with transient conditions such as coughs and colds, but also chronic disorders such as farsightedness, lower back pain, high blood pressure or diabetes, why can’t we accept that it might also be normal to be psychiatrically ill at various points in our lives? The answer seems to be that psychiatric disorders carry a much greater degree of stigma compared with medical conditions. People worry that psychiatrists think everyone is crazy because they make the mistake of equating any form of psychiatric illness with being crazy. But that’s like equating a cough with tuberculosis or lung cancer.
