So, what are the chances of Vulkan drivers from devices makers "follow the tradition" of their OpenGL drivers and only implement half the spec with lots of bugs and lack of functionality
The guy is a multi-billionaire. $900k would be like $100 for most of us here: nothing.
From around 44 minutes in at http://thisweekinstartups.com/maren-kate-donovan-zirtual/:

You have an $11 million run rate business now. It's just extraordinary. I think the investment community has probably missed this investment. I think they really should be more focused on it. I consider you like a sleeper. At some point the investment community is going to look at this like, well this could be like, similar to an Uber or Lyft or one of these companies that really scales because there is such a huge opportunity to arbitrage between the cities and the work and when you get into the specialized stuff, it's going to be game over.

It gets even worse towards the end, with Calacanis going full talk-up-my-investment mode, gloating about Zirtual's revenue and margin numbers, and the founder's abilities.

That was Friday. Today on https://twitter.com/jason:

1/sorry to hear about @Zirtual shutdown today, as a fan of the service & as an investor. I don't speak for the company & have limited 411.

2/we have @marenkate booked for @TWistartups for this past Friday for weeks, I found out about issues on Saturday while out of the country.

3/wouldn't have suggested being on the show Friday if I knew they were shutting down Monday; confused at a $11m a year business imploding.

That's not "freedom" you're describing.

You're wanting "freedom to pursue "hobbies" and free "perks" without having to work for it" for yourself, at the expense of the general society. And by expense of general society, what that really means is that someone with the means to production/capital/etc has to part ways with some of his (labor, gasp he's no longer free), in order to fund your "free" lifestyle.
I don't think that's actually true; otherwise how would they be a part of a community with other like-minded people? How would they authenticate themselves to one another? Hell's Angels are another good example.
Good catch. I'll make sure that gets corrected.

Ask HN: What am I missing with Farmty, a marrage between Alibaba and Etsy?
Hi,

I've been reading HN for ages, and it is safe to say that people here inspired me to build a SaaS product for something I do care about.

Landing page: http://www.farmty.com

Right now it is a one-man startup that aims to provide a platform for farmers and independent growers to trade and sell their produce online or offline. It is called Farmty. If it isn't clear enough, it is basically Alibaba and Etsy merged together.

While developing it alone wasn't easy, I do think I've arrived at the hardest part - get it out there and start to grow it. (While the landing page is nothing special, the full backend runs on AWS, and is fully functional... if anyone is interested I'm happy to post more info or answer any questions etc.)

What I'm looking for is kind/honest words, advice or any feedback that could help me in any way. Please be gentle - I'm only trying to get somewhere ;)

Thanks in advance...
A nice article to manipulate your competitors from doing a market survey!
High if Khronos doesn't provide a comprehensive certification suite. Dunno what's the status for Vulkan, but OGL/OGLES versus D3D (any feature level) is a joke. :S
> I didn't flag it, and I wasn't advocating that. I asked about tagging.

I probably posted a generic reply instead of answering your specific question. Sorry about that. In general, we're reluctant to add tags for things like that. The noise might outweigh the signal, and HN has always been a bare-bones operation. But we'll think about it.
Interesting article but for a different take on a statistical approach to the market, curious if any peeps on HN are into volatility trading?

From what I understand a lot of the "DIY vendors" cater to the equity crowd, meaning people who build their models on technical indicators (MACD, RSI, advancers/decliners ratio, Fibonacci golden ratio retracement, MA); you build your model of some combined signals, back-test it with historical data on some tickers to see if it's promising.

I trade options, specifically selling 1.8-2 sigma calls and puts (with 90%-95% probability of not being in the money) on the major market indices (SPX, RUT, NDX) 45 days out from expirations; so kinda of like an insurance company underwriting policy or a bookie taking bets from both sides.

When the market moves against me (e.g., Grexit), I try to hedge my exposure to that side of the market by buying a longer dated call and put neutralizing the delta of my overall book (kind of like going to the re-insurance market to hedge my book); and also adjust the spread or close it entirely for a loss if risk/reward no longer works out.

But I never trade directional or have any market outlook; and do this systematically and only thing I change is sizing my book depending on how high VIX is (insurance premium/market fear).

This is a well-documented and traded strategy for peeps who follow, say TastyTrade, volatility arbitrage funds or just options in general. Just curious if anyone here also trades this way?
S3 SLA is actually for only three nines (99.9%) or 8.76 hours / year or 43.8 minutes / month of downtime: https://aws.amazon.com/s3/sla/

CloudFront offers the same availability. Many CDNs offer no more than three nines. Some claim 100%, but there will eventually be faults. Most do really well to not have recognized outages, but I nonetheless think they offer 100% to guarantee so that you always get credit for any downtime rather than guaranteeing they are never down.

You can look at replicating files to multiple providers; the following shows what kind of uptimes you can expect from the big players: https://cloudharmony.com/status-1year-of-storage

Why would playing the market result in higher returns? Why would you think day trading would outperform buying-and-holding? The research all shows the opposite.

That's been going on since the late 1970s, when personal computers first became available. It worked back then, because few were doing algorithmic trading at the time. Now, everybody is.

There's new interest in systems which look at external data sources such as news items, rather than just at market data.[1] They have a chance of picking up something before the market reacts. But that's already widely deployed; about 15% of HFT operations were using it by 2013.[2]

> requesting the broadcast from your provider

This is identical with HTML. I request a page via HTTP, and they send it to me. What I do with that page is up to me. Just like I can mute a commercial on TV, change the channel, or shut the TV off[1].

> they have some say as to how they package up the data you ask for.

Correct. The problem comes when this is extended to include what someone does with that data after it changes hands. We have historically described this situation as the publisher's rights ending at the "1st sale"[2].

Anybody that wants rights to restrict what someone does with the data they are sent should get a contract that describes these requirements. (an EULA, writing at the bottom of a previously-requested page, and the HTTP headers are not contracts)

As for paying by CPU usage: I'll run the javascript and load the image or video files only after I receive a payment for electricity usage (CPU time) and compensation for my lost personal time. Hourly rates are available upon request.

> The right solution is somewhere in the middle.

The right solution respects users instead of trying to move the Overton Window[3].

The 'zero-sum game' part is meaningless and adds no insight here. It doesn't matter whether you believe trading/gambling is zero-sum or not.

For instance, imagine you have a poker-playing bot at a poker table, where the house takes no cut of the stakes. Zero-sum? Yes. But your bot has to be better than the other players, and win more than its running costs in order to profit. Now imagine the same situation but the house does take a cut. Zero-sum? Not any more. But your bot still has to be better than the other players and its running costs in order to profit. The house 'rake' just increases your operating costs.

I think you are confusing the issue with large scale HFT (where companies pay more and more for slightly faster comms), which is a world away from the trading strategies the article is talking about.
Boeing sometimes puts some extreme maneuvers into the approved flight test card, which is performed with FAA approval.

There has been several cases of 737s being rolled (accidentally) without damaging the airframe.

When test pilots fly extreme maneuvers on an approved test profile, its usually done at high altitude, not airshow flyover altitude.

Before the famous 787 demo flight, the pilot flew the maneuvers in a simulator, and did some practice at higher altitude before doing a low altitude demo routine.

This question and answers are gold! The answer with LaTex (http://mathoverflow.net/a/213268/42557) and the diametrically opposed comments to it illustrate problems with Tex.

Common register allocation across different bytecode interpretation sequences was one of the things specifically on my mind that could be tuned using a high-level assembler.

Very suboptimal might be a slight overstatement. I can see a way, given known register calling conventions, that you could write an interpreter written as tail calls and post-process the machine code to effectively JMP instead of CALL. Guaranteed tail calls would save you a bunch of effort, and register calling convention would give you some guarantees about consistent allocation.

> As a last-ditch attempt to solve the problem, they made it yellow

Amazing! I could almost write a script for the meeting in which that solution was decided upon.

Rough sketch:

Idea is proposed by one individual at level N in the hierarchy. Some cursory justification is provided, based on theory from a design article they read, they think, or maybe it was a youtube video - doesn't matter: Yellow attracts attention! Green makes people want to proceed! Red makes people want to stop! It's so obvious.

Numerous objections are raised by individuals at level < N in the hierarchy, who have a fairly deep understanding of design and have thought a lot about the problem. The objections are considered briefly, and then summarily ignored.

Meeting concluded.

Stored procedures are usually considered part of the schema. They can be diffed. I know the Visual Studio comparison tool is able to diff databases but also generates code to check affected stored procedures for errors after a table schema change.

I would still recommend changing stored procedures through UPDATE scripts and having this change scripts immutable. (Ideally not just immutable but also idempotent and with forward and backward scripts to undo change.)
In your rush to attach the pejorative label of "bully" to Jobs, you've missed the point of the story.

The developer made a tool which let Jobs rapidly iterate through a number of ideas until he saw what he liked. There's no reason to believe he knew what he wanted until he could experiment in a low-friction manner for himself. That's what the dev gave him.

Yes, I do indeed believe that means you do not understand those "questions". As such, your insistence that major issues deeply dividing society are solely one-sided, and establishing policies based on the one-sided view, leads to what I shall colloquially refer to as "civil unrest". Don't dismiss the guideline simply because it doesn't lead you to where you want to go.
Another comment in this post:

>I've had the joy of seeing code which broke completely if you removed the line while(false){}. Some hideous synchronization bug was solved by this line, and while it obviously wasn't the right solution, simply deleting it produced bad outputs. Profilers and processing tools are, as you say, other likely causes of dumb-looking code choices.

This is interesting because there's like, a role-reversal thing going on here. I don't know if you're aware of it, but I tend to go to the mat for the underdog, the abused (the pejored, if you will!).

But that's it. I'd oppose somebody if I observed them on the attack, but never start anything. And that behavior was systematic. Frankly, it's exploitable.

So, I dunno. I'm in flux. Rethinking some things. Practicing allowing myself to think, even SAY--"you know what? Some people suck, objectively".

I guess your comment "doing their best to figure out a path for themselves through a mystifying world" inspired me to mention that part.

I think the upshot of rejecting some people is that you can lower your cognitive load in group situations. You mentioned it: categorization. For me, it's a pretty fundamental shift (that I'm not sold on yet): actually adding a new category: those that I'd leave behind first in some sort of lifeboat situation. I know that's really harsh. Fortunately real-world lifeboat situations are rare? Without such categorization, you can land in some REALLY dumb situations...

Why not timestamps + description? This way, even if you create migrations on different branches, you don't have version number overlap. Rails does that if I remember correctly.

Algorithmic trading is more than just HFT, where every microsecond counts, and where these small-scale day traders cannot compete.

Your example of analysing new items is a good one. If you can spot a better way to predict stock or currency movements by a cunning new way of processing news feeds, then you could potentially profit from it without having to rely on speed of execution.

People have been using computers to do stock analysis, as you say. But this doesn't make it a solved problem. There's money to be made if you can do it better than the others. Of course, the competition is very tough.
Ahahah! Thanks for the clips and good points! And in spite of how formulaic pop music is at the composition level, I still think it would be harder to AI a convincing pop song than a classical piece, because so much of pop's information is encoded in performance, which ironically is thanks to the ability to record instead of notate. You are right that it would be much harder to fool an advanced listener. To me the videos you shared say something about this whole AI problem and the future of the music market, which is that interactivity and engagement with creation in musical forms and performances will replace the traditional performer/audience role format. I think the problem of artificiality, which we might as well call the ease by which music can be entirely reproduced by algorithm won't work in the traditional mode of performer/audience. Instead all the power to cast musical forms that are effective at entering and altering the psyche of the individual listener will be sublimated and abstracted just beyond their conscious intention, so that they can become a player in the musical work. This is what happens now too, and it is why the AI performer won't work unless as a hoax in our current format - the participation and identification with the singer are fundamental to the music experience. Those country singers are singing about manly things: mostly getting girls into bed. You may be able to program a compute algorithm to crank out shallow man tunes like that, however it will have to also be tuned in to the culture of the times, because I can hear a lot of change in those country tunes than country tunes of ten years ago. There are layers and layers. But primordially, there is identification with cultural realities, and these might well be generated by machinery, and already are, however they will fundamentally align with the desires of the human creator, unless someone creates an artificial consciousness to compete with our human one. So bar that, musical AI will enhance and entice us towards a deeper and better human experience, which the machine knows not!
