I can't answer your actual question, but I can tell you that there are situations where you can get an excess of the wrong kinds of attention and it can be very problematic.

Perhaps calling it "stealth mode" is a bad tactic. But there is (or can be) benefit to doing some of the legwork and not being too share-y (or not seeking too much publicity) at a certain stage, especially if it is something you will need to "cram down their throat."

Babies gestate in darkness. Sometimes, projects need to do so as well.
Your description reminds me of the '90's Apple that had so many fricking Mac models that ordinary mortals didn't know what to buy. I remember fielding those questions more than once, and only barely having an answer because I frequently browsed the hobbyist and trade press at that time.

200\* Apple became one of a few models choices, each designed to (for something of a premium) deliver a consummate experience within its niche.

Apple buyers -- both professionals and premium-paying consumers -- want something that "just works", and works well.

For Apple to foist the Emotibar on them, before solving these other problems... Back-asswards.

Glad to see Leo doing this, his fund was an investor in my company so I've gotten to experience a few rounds of Leo office hours, although we didn't call them that at the time. He was very helpful and smart in my experience.

On another note the usage of Tit-For-Tat seems a bit weird in this context since I think it's generally reserved for retaliatory exchanges rather then beneficial ones.
> The congressional GOP's approval rating is (or was) at record lows. It wasn't about pleasing their electorate.

The only approval rating that matters is the approval rating from their own constituents. And that's always been a lot better than their overall approval rating.

Or to put it another way, "everyone thinks Congress is doing a bad job, but they think their Congressman is doing a good job".
Right. But the way it was stated in the article makes it easy to think of it as the universe requiring rather than the observer requiring. The other versions explicitly get into that kind of nonsense; I wanted to state the weak version in a way that made it clear that it didn't go there.

(I suspect that this page states the weak version in that way in order to make the other versions seem more similar.)
Reading Linus talk about game development had me confused for a bit there. In my mind Linus is the kernel guy.
Except the exact same criticism applies to the alternative: everyone involved in allocating and spending the money you give to build and supply that natural gas pipe is also selfish and short-sighted, and is much more likely to try to enrich themselves over providing a good service.

At least by giving directly, it's easier to control that the money actually gets to the people it's supposed to, even if they don't spend exactly as we might wish they did.
I've been promoting this as the real solution to unemployment - An explosion of incredibly custom and niche art of various forms. We're already seeing the early signs of this with the explosion of indie games and youtube personalities. Not simply personalities like PewDiePie and Markiplier, who are big enough that they're more and more traditional media, even if they came from simpler roots - But the shows that have a few thousand or even hundred viewers. It's not profitable yet, but it's getting there. Patreon is a very key component of this - A few bucks here and there, and the creative class can earn a living - Or simply supplement a part-time job.
This is a global issue. History is written by winners. There are a lot of cultures within China or Russia or any other country that have been destroyed over time in the goal of national progress.

History unfortunately does that to nations and peoples. The average European is as ignorant about the Sami as the average American is about the Tonkawa.
>This is called a "relative return" strategy. Suppose the benchmark falls 70% and the hedge fund loses 50%. Your hedge fund manager has lost half your money, but has beat the benchmark by 20% (i.e. "positive alpha"). How does a fee based on alpha work in this case?

I'm not who you're responding to, and I've never heard of "relative return" strategy, but it makes perfect sense to me and your hypothetical poses no confusion in my eyes. If the benchmark (agreed upon in advance of course) would have caused my money to go from M to B by the end of the year, and the hedge fund actually caused my money to go from M to H, then they get paid some percentage of H - B. It's completely irrelevant what M is in relation to H or B.

It varies investor to investor. For reaching investors who only take warm intros, it's hard for me to help. There are other investors, like me, who reply to cold emails when they're personalized/well-targeted. Founders don't need any kind of audition to talk to the second investor group... they just need to send a relevant email (i.e. not "Dear Sir or Madam, here's a form letter about my company that I'm bcc'ing to 50 investors..")

Problem: How to find reliable and quality professionals?
Hi, my name is Erick Fernandes and i'm from brazil. Here we got a problems when we have to found eletricists, Carpenters and even progamators with Good quality. In your contries you have problems like this? Do you use any mechanism to know if the professional who will carry out the work is of quality?
Well to the settings stuff yes, see something like "cookie clicker" for a (IMO bad UX) example. And you can more easily control how much data it stores over a certain point, as all major browsers make you confirm via a dialog that you are giving permission to use the requested amount.

But to keep this from turning ugly, my point was more that you need to take into consideration what you'll need for your app.

If it's an application that basically only exists as an interface for data stored in a backend server, then giving them the ability to exist after bankruptcy is pointless. However if it's something that needs root access and will frequently be used and installed on a system without internet access, native is better.

And saying things like a native app is "less bloated" when it takes literally multiple magnitudes more time to install and run with significantly more permissions to your whole system is silly.
> There’s another factor that makes the threat of asteroid impacts a unique opportunity for global unity. Unlike some more localized natural hazards, like volcanic eruptions and tsunamis, these kinds of impacts are theoretically preventable. “It’s the only natural disaster that we really have the ability to—at least in principle—prevent,” says Barbee. “That creates a certain type of international collaboration that is very unique.”

The desire the unify the world is powerful. It might even be deeper than any surface issues. Sometimes I wonder whether, if we invented some machine that quickly and easily pulled carbon out of the atmosphere, people would adopt it or still continue to push for a global agreement. I think they'd adopt it but then they would look for other ways to unite the world.
What is "minimalist" about this book?
Hey Joe! Oops, my bad on the word choice. I read a book on social altruism a while ago which talked about tit-for-tat in the context of game theory (i.e. why people do nice things for strangers). I didn't realize the term has a mostly negative context.
Ask HN: How Would You Design a “Net Invisible” System
Answering in the spirit of an IETF RFC, how would you design an "Internet-invisble", zero footprint (or equivalent, spoofed, etc) computing system, from hardware to software? How would you draft the base requirements for this stealth system? What existing technology (standards and protocols) would support such a project? What new protocols, hacks and/or experimental tech (quantum, bio) would be needed to make it a reality?

Understand "Internet-" or "Net-invisible" to mean the state a device is in once it has connected to the Internet, or any network for that matter, wherein it has no visible presence to the network. How that is accomplished is irrelevant as long as the illusion of non-existence, or "internet invisibility" is achieved. This might seem ridiculous at first when once considers the volume of communication, handshakes and other functions that are executed and required to connect to a network, but then that is the challenge of the question, assuming some version of this is actually possible. The product would then be a "stealth computer system" that one could quickly access and utilize without fear of discovery.

If the ram's power use is the main problem, then that disproportionately affects low-power uses. There's no reason to think gaming would have a similarly crippled battery life.

Any idea how long the MBP lasts if you peg the GPU?
But compared to the web, native applications are significantly worse in these areas.

Especially on that first point. I can go to the vast majority of web apps on just about anything with a browser and get it up and running in less than a second knowing nothing more than a domain name.

And there's "cross platform" then there's "cross platform". Something like QT is amazing, but you are still looking at the big-3 desktop OS's, and maybe the big mobile guys if you work for it. A web app includes all of that, plus my TV, my car headunit, and even my damn watch! (I often use a web home-automation app from a browser on my watch, the UI adapts pretty damn well for quick light-flips)

Nothing is perfect for everyone, but just because it's been done since the 80's doesn't mean it can't be improved on. And as always it depends on your actual needs. There aren't any "better" and "worse" architectures.

I used to think this, then acquired a Macbook Air from work. Its is actually quite nice when traveling with only hand luggage to squeeze the laptop into a relatively full bag, yet you still have a big screen and keyboard. Not sure I would pay a lot more for that if I was paying myself, but it is nice to have.
Leo more a question about your investment thesis. I can understand the focus on B2B startups with a real competive advantage, but why limit to minor traction? Minor traction is unlikely to provide much insight as to scalability and passing on this requirement would allow you to invest on much better terms.
As a python guy learning perl for fun, I've found simple string interpolation and heredocs to be very nice.
The rule of thumb is that you can survive:

3 minutes without air

3 days without water

3 weeks without food

So you're probably not going to die without food if you go even for some days without it. In fact, many people regularly fast for days on end, some (such as people on hunger strikes) have fasted for weeks.

Of course, all of the above rules of thumb are subject to modifications based on things such as the amount of physical exertion you're under, your health, the weather, etc. If you're doing lots of exercise in the heat, you're going to need a lot more water than if you're lying still in the shade.
Hey, thanks for the answer. Maybe I wasn't clear about my point, but the question is not really about what is ES or what is Kafka. I am sure Kafka can be used in ES systems, but Kafka alone is not a complete solution for ES systems, it merely routes and stores the events.

I think people are doing ES in different ways, and I wish I could hear about the architectures around: what kinds of internal services people have producing and consuming the events, where they process the side effects of the events, where to store the events and also how they are updating the databases used by the applications. I mentioned Kafka because it plays a major role for several implementations, but Kafka is not the whole story neither it is obvious how to deal with it.
There are some funds that have much better incentive structures than the standard 2-and-20. In particular, some funds charge an incentive fee over a hurdle rate of say, 6%. Even more fair to investors - this hurdle rate compounds and is subject to a high water mark - where the management company must beat the previous highest amount attained by the fund by the compounding hurdle rate. Additionally, some managers also credit any (usually lower) management fee to the incentive fee.

The downside is that the incentive fees get much more complicated - too complicated to lay out here. I've modeled the scenarios in the following Google Spreadsheet (feel free to copy and play around with this): https://docs.google.com/spreadsheets/d/1RlB4iwg42dEa-atdti4H...

If you do check it out:

Notice that in the [high ret] scenarios, there's little difference in total fees charged between the "fair" 6% hurdle and the 2-and-20 scenario. However, in the [low ret] scenario, the fee difference can be quite substantial: $227k for 2-and-20 vs $70k for the 6% hurdle scenario. And the resulting

Please feel free to copy and play with the values if you'd like. I'd love to discuss in more depth.

The 6% hurdle is a reasonably fair expectation of annualized stock market returns going forward for next 10-20yrs. If there's sufficient interest please reply to this comment and I can detail reasons why, most likely in a full fledged post.

(Over the next 3-5 years, I believe "market returns" - defined as those received from SPY ETF - are likely to be less than 6% from this point (Dec 23 2016), possibly significantly so.)
I 'tried out' a standing desk experience with an overturned packing crate, a piece of plywood.. for the right height for keyboard/mouse. And then two reams of paper to bring the laptop display to the right height above the keyboard. Haven't changed it for over a year because it 'just works'. So don't let lack of money or equipment deter trying it out. An anti fatigue mat helps, and a bar stool can let you sit to take a break without reconfiguring your desk.
Ask HN: What are your MVP marketing hacks?
Offline is not a mere feature you can bolt on to existing architectures because you are really building a distributed system. Architectures that work well for distributed systems and especially p2p architectures thrive in this environment. Elsewhere in these comments people are discussing command queues, but this idea presumes that servers are somewhat reliable and that all operations need to go through a centralized point of control and failure. Instead, you can take this idea further and implement a kappa architecture (sometimes also called "event sourcing") where you maintain a log locally on every client which is the source of truth, not a server. When a network connection is available, you can replicate the log to a server or directly to other clients. You can build indexes (materialized views) that sit on top of this log to answer queries more quickly than reading the entire log out every time. You can also blow away these indexes and rebuild them from the log whenever your requirements change (migrations).

Unfortunately the web is missing a few pieces that would make it a very good platform for fully p2p, distributed apps. Service workers are a good start, but they have a 24-hour upper cap on max-age of the service worker itself, so users can't trust on first use (TOFU) and then be more secure against kinds of active targeting. The suborigin specification and iframe sandboxes for distributing apps offline and p2p would be much more useful for offline sandboxes if they didn't require that a server send an http header. These will become much more important as the web bluetooth API matures, which can allow distributing user data and application updates in a totally offline environment.

Even without being fully offline, it's very odd that when an automatic update to android or windows comes down the pipe, people in remote areas download the exact same bytes from servers in America over and over again, all over a thin pipe. They could fetch that data from each other and save a lot of money on bandwidth and data caps.
I don't think people care about thickness specifically, but about weight. And weight is (for the most part) correlated to thickness.
I think the answer is rather simple and straight forward: just as there are many people who have created different GNU/Linux distributions because they thought changing a particular aspect would be an improvement, people want to improve security and offer their version.
I wish I lived in your world. Mine only seems to be getting more and more divided. None of the leaders of the free (or unfree) world seem to have any desire right now to 'unite' it
I don't know docker should be considered security sandboxing. From https://docs.docker.com/engine/security/security/ :

True enough, but on the other hand, how can you be a hero if you can't tweet about it? This particular conflict seems to be characterized by a rather unusual combination of (somewhat) irregular troops and heavy artillery, so creative use of consumer electronics for both morale and maths should not be too surprising.

Besides, troops making ends meet with old soviet weapons stockpiles are not alone in using consumer electronics to augment their military hardware:

I guess these guys had more than enough process in place to avoid the mistakes made by Ukrainian artillerists, but then the baseline technology from which improvisation starts is supposed to be much less outdated in the USMC than in Ukrainian forces (who in considerable parts are hardly more than post-fact legalized militias, including an international cast of "lifestyle warriors").
I think it might have more to do with OSX than it does with the hardware itself. OSX is really really good at managing power consumption. Windows, not so much.

lol, yes sorry. got bit sounds like I meant the opposite.
I see your point, but I would say two things:

1) You might be underestimating how far a typical server configuration is from least privilege. It's true that you need to write to database tables or a queue service for the app to work, but a typical configuration has the capability to do hundreds or thousands of other things that are not necessary for the app.

If you have a PHP app running inside a Apache process, how many system calls are needed? What about PHP as a FastCGI process under nginx? Linux has 200+ system calls, and I'm sure the number is a small fraction of that.

What about the privileges for connecting to local daemons? Most people are dumping huge Linux images into Docker and then installing tons of packages by default. Last time I checked, apt-get install will START daemons for you.

It takes some work to figure out what privileges a given application needs, and that's probably why people don't do it. But I would contend that much less hard, and much more bang for the buck than a lot of the techniques mentioned in this paper.

2) You might be underestimating diversity of privileges needed for different application components ("microservices" if you will). For example, in distributed applications I've dealt with, the auth code doesn't need to talk to all the same back ends that the normal application logic does. If it lives in a separate process, which is a good idea for a number of other reasons, it can have different privileges than the rest of the application.

In any case I view this as a kind of "walk before you run" type of thing. If you can't even figure out what privileges your application needs, how are you going to get programmers to add pre- and post- conditions, and apply symbolic execution and techniques like that? The paper sounds absurd and divorced from the realities of software development.

Now that I read the paper, they do devote just 2 pages to "containers and microservices" (which are weirdly buzzword-y terms for a traditional practice). It still seems unbalanced to me.
>It's astonishing to me that I hit Ctrl-F and searched for "sandbox" and "software compartmentalization" and there are no hits in that doc.

They use the term container. It's a subheading:

2.2.1 Operating System Containers

"...Container-based isolation can clearly reduce the impact of software vulnerabilities if the isolation is strong enough."
VC having an accurate price. But, also those price swings in your example where odd. Useually you get steady gains then big drops followed by steady gains across years. Not big gains followed by years of losses. If nothing else inflation is pushing up prices.

+10% +90% -10% -10% -10% is odd. More likely pattern +10% -50% +10% +10% +10%

PS: You can model the s&p 500 for 10 years with each model and compare gains. But, try it every year from 1950 - 2015 not just one year.
