Ask HN: Why my app marketing approach is not working? [videos included]
Hi Hackernews,

As I was struggling with phone addiction, I decided to create an app to help me control my addiction while enjoying the benefits of social media and smart-phones.

What does "No Notification Hour" do?
It disables notifications for an hour and at the end of the hour will let you receive all the notifications that you have missed.

what have I done up to this point?
I have created 4 sets of ads for Facebook up to this point, spending nearly 20 GBP, and getting 4 installs through them.
The ads contained 2 videos, one for young students in the UK and USA, and the other for young persons who live in Latin America and like meditating.

I don't know what another group of people I should promote it to that would give me a better result than the ones I have received.

I have created the following videos and used them for my facebook ads.

https://www.youtube.com/watch?v=XFu41abtPIA

None of my approaches to bring more people to use my app does not seem to be working. Can anyone help me find out what's wrong with bringing more people to use it.

Is there any way for me to improve on the marketing aspects? or is my product just not fit for the market?

Many thanks,

Usually it would be number of legal moves. Of course this would also change throughout the game as pieces are removed.
Could you point us to some of those togetherJS apps? I just recently learned about it in the context of collaborative browsing. How is this related to collaborative text stuff?
Hmmm, this is a pretty relevant reversal of roles, when you think about it. Usually we have individual users running around causing mayhem from beyond the boundaries of jurisdictions that might try to seek damages or prosecute crimes. Usually it's individuals from other countries crossing distance to attack organizations.

Here, we have an organization damaging an individual with possible criminal actions, from beyond the individual's reach. Discriminating based on general appearance isn't always an acceptable choice, when it's not relevant to business.

There might be no recourse in situations that cross different borders and jurisdictions...
So? That does not make this problem any less real, nor does it make it go away.

The dropshippers are likely to be the last straw for me. Filtering out all the promoted listings and fake-review-based listings is enough of a chore. Filtering out all of the duplicates as well is just too much. I shouldn't have to work my way down to the third page of listings to find the first one that legitimately deserves its high ranking.
It is board size for Go, because the starting condition is an empty board. For chess, I would expect the complexity to also be a function of the number of pieces, and possibly the types of pieces.
It seemed to me that the article was only using the fact of JSON use as more evidence of modernness. It implied that JSON didn't map that well into their problem space but they overcame.
Since atmopsheric transmission windows dictate which kind of wavelengths you'd use for a laser weapon and which kinds of wavelengths can efficiently be created, multilayer coatings could conceivably reflect a lot of incoming power. In the 90s, the US DoD asked for 'laser armor' and got photonic crystal structures (1-d multilayer) that omnidirectionally reflect [1]. Further details about this are also available in the book "Photonic Crystals" (preprint for free here [2]).

What is probably way easier though (and actually survives launch and particles hitting it and is already proven in practice) is to use ablative heat shields on missiles. The materials available are already optimized for mass vs. effectiveness due to the engineering constraints in space flight. Missile optics would probably need to be coated though or distributed.

I don't know why you got down voted on this. My experience of EV vs ICE (sometimes in the same vehicle - daily driving in a Prius plug-in) agrees entirely with your comment: the lovely EV experience of linear, quiet acceleration is so pleasant compared to driving a petrol car, even an automatic. And my Prius in EV mode isn't even a that great an electric experience compared to that of an i3 or 2018 Leaf.
I'd expect CPU rendering to work pretty well on a game from 1996. I could be wrong though.
> So the correct game theory play against someone reneging on a false promise would be ...

To be public about the false promis removing the ability of the rider to make future deals thus removing their ability to compete on equal terms with other competitors and seriously damaging their carriers. If you want to model the real world using game theory, then you have to include the fact that players can communicate outside of active competition, and that players have reputations, tarnished by their bad faith actions.
Ah yes, mixed up my techs. I meant embedded Chromium, not WebKit.
MtG is played by choosing 60 cards from 20k. Everything is finite. There must be some generalization in order to make it noncomputable.

There are probably many games that can somehow encode a halting problem if the board size is made arbitrarily large.

EDIT: This from the real abstract sounds very strange:

"Our result is also highly unusual in that
all moves of both players are forced in the construction. This
shows that even recognising who will win a game in which neither
player has a non-trivial decision to make for the rest of the game
is undecidable."

Last time I checked retail prices were around 0.30 to 0.32 $ per Wp for large customers. So your high efficiency, last tech 300 Wp module would be around 100$ including shipping for large orders. Could go up to around 120 to 150 for smaller volumes. Of course, market prices may vary depending on demand and availability.
> And I always used to wonder why they were so crazy about their Apple laptops when all they were using was the terminal. Why couldn't they install Linux on way more powerful hardware at a fraction of the cost.

It's less about the power of the hardware, and more about support. A top end 13" Macbook Pro is $2000 for an i7, 8GB RAM, 512GB SSD a passable integrated GPU and 2280x1800 resolution.

A Dell xps 13 "developer edition" comes to just shy of $1700 with very very similar specs and a similar build quality, which is the same ballpark. People aren't buying macbooks because they're expensive, they're buying them because the hardware support is (well, was) good, the software is good, they work together, and there's a fallback.

Install any linux distro on a HP laptop for a third of the price, and see how far you get in terms of support.

For some products, I wonder if using glass would result in less transport costs over the long term.

I think specifically of milk bottles.

Plastic milk bottles have to be brought from hundreds of miles away to my local dairy. Post-consumer, they're trucked close to 50 miles to the nearest landfill, or a couple of hundred miles to the nearest reprocessing company, or thousands of miles to another country's reprocessing facilities.

By contrast, glass milk bottles (widely available in the last five cities in which I've lived) are trucked to the dairy once. Then post-consumer they get returned to the same dairy for cleaning and re-use over and over and over again. Some bottles have clearly been through this process many times, as they show signs of wear and have less clarity than the random new glass bottle.

I prefer re-using things to recycling things, but I'm apparently in the minority. When I mentioned glass milk bottles at work once, nobody knew what I was talking about, even though I know they've seen them since we all shop at the same supermarkets.
Interesting article although light on the technical details of how they are restoring the neon glass signage. If the glass was well made then they can simply replace the electrodes and burn it in again (bombardment). However neon glass has changed a lot over the decade to make it easier to bend, hopefully the glass mixes old and new are compatible long term.

Down from NL. Github status page says "Partially Degraded Service". But no ETA and no explanation. Time for long coffee break.
The whole sentence makes even less sense:

"Though similar to role-playing fantasy games such as Dungeons and Dragons, it has significantly more cards and more complex rules than other card games."

As if similarity to D&D said anything at all about number of cards relative to other card games.

The number of legal moves is an intermediate calculation. The input is the initial game state, and the output is usually the number of possible final game states.
>I did not try strong psychedelics but the problem with them as with any kind of drug is the effect wears off inevitably. If you feel great for some time, going back becomes even more terrible than staying there, because now you know there are better states.

This is hard to claim if you've never tried it. Personally when I do a shroom trip I don't even feel like doing it again until months later. I've done it like 8 times in my whole life, usually for fun with friends but it always ends up enlightening and spiritual. The effects are permanent in a very good way. It's a trip, same as you travel to a different exotic country and explore a different world, the memories, the feelings you experienced and the knowledge you gained will stay with you.
Maybe that is why AMD open source drivers still doesn't properly support my travel notebook APU.

So where is the great hardware video decoding and the GL features fxgl was capable of?
Thanks, from reading the abstract, is sounds as if they have an algorithm for the halting problem.
Treatment that is 100% effective when properly administered but has a 5% chance at being properly administered is still not a very good treatment. These two routes are not mutually exclusive.
I think you are misunderstanding the article. The point is that when the game is considered as a computation, the problem of figuring out who is going to win is not computable. Like every discussion of the halting problem, this is about whether or not a program exists that can calculate how some other specific program will behave.

Fingerprint sensor, UMTS Modem, HiDPI Screens, especially mixed with regular screens, there were issues with low cpu power states or so on the recent carbon X1, my desktop sometimes locks up when the laptop is docked with external screens connected and only unlocks when I undock (it doesn’t crash, it seems to be incapable of placing a window, once I undock and redock everything is fine).

From the paper:

"In this work, we solve this problem by reformulating the construction to exclusively use cards with mandatory effects."

So it's more a of a subset of MTG's rules. Still, there are commercial video games out beyond MTG and they've been out for some time. Why has the game theory field not kept up with them?
> One way to solve this is to fallback to differential sync when syncing huge offline edits

This is another question -- does automatic syncing make sense for huge differences in users' contents? The answer might be no.

OTOH, isn't this a rare scenario? How perfect it has to be?How much of a compromise can the users accept? These are interesting questions which shows that creating this kind of software isn't easy -- both from technical and UX point of view.
> One aspect was that get_user_pages doesn't give you a linear block of memory. I wrote the grotty C code to dequeue messages from the non-linearly-mapped circular buffer. The message headers could straddle page boundaries, so I copied those out into temporaries before working with them. I think there was some attempt to avoid making unnecessary copies of the bulk data.

Open question: would it have helped to have a CMA[1] region managed by a kernel module and mapping that memory/regions of that memory to user-space using remap_pfn_range[2] instead?

Confirming I can't even get the home page to load from the UK, Hungarian colleagues aren't having any issues
I have to disagree on that. At least Terraforming Mars and Hanabi have a playtime limited by ever-dwindling resources. I don't know the other games, but I suspect they also have some kind of supply that has a limit in how much it can be used/aquired.

MTG has ways to return to a previously seen play state, technically allowing a game to continue infinitely, depending on your deck, of course.
Call naming just proves that it isn't worthwhile dealing with such community.
Wasn't there a post here on HN a month or two ago about how conhost is the only windows program with crazy low latency (tens of milliseconds from a key press to that ending up on the screen), and it was all done by not using winforms/.net/html5 like all other apps.

Presumably, the new terminal will have the same lag now other windows apps have?
There has been chatter about doing this for over 8 years in the WordPress bug tracker, and I vaguely recollect chatter about it even earlier, around when automated updates were first introduced. What's surprising is that this hasn't been done earlier, and speaking personally I do not think this deserves any praise - on the contrary.

That's not their argument either. The gist of their argument is that you can combine those cards and the legal moves they allow to encode a Turing machine and thus determining the winner is equivalent to solving the halting problem.

> "Our result is also highly unusual in that all moves of both players are forced in the construction. This shows that even recognising who will win a game in which neither player has a non-trivial decision to make for the rest of the game is undecidable."

It's not so strange: the game is Turing complete, so the winner can be undecidable because who wins is the result of some arbitrarily complex computation.

Imagine we play a "game" where I win if there's a nontrivial zero of the Riemann zeta function with real part not equal to one half, otherwise you win. Neither of us has any decisions to make in this game. It's still very difficult to determine who's going to win.
I'd claim strongly, that any game with:

- finite number of pieces (eg. cards)

- finite number of actions each round

- clear endgame criteria

is computionally solvable. What comes with randomness is stochasticity, but if that made game unsolvable what about poker (solved for limit heads-up) and even scrabble?

Probably it's kind of semantic problem. I'm not complexity nor game theory expert.
I've been running LineageOS on my OnePlus3 for the past couple of years (since the whole telemetry app scandal in fact) and I highly recommend it to everyone. I don't have a bad word to say about it, in fact.

Depends on what you mean by "decent performance". PCem emulates on hardware level (it uses stock BIOS firmware, for example), and it can run Win95 with about the same perf as a typical machine circa 1996. And it also emulates 3dfx.
I found that I could eventually power through the paper. I thought it was beyond me at first. Then I got angry and just shoved piece by piece into my head :) Not in linear fashion, and it didn’t happen quickly. Actully not that slow either once I got going. I found I was maybe rather more of a paper-reader than I assumed I was. Probably you too!!
Not at all, they just made it official that we are forced to rewrite those apps.
Probably better to use modern Prolog instead?
Also, most of the cards are probably some basic lands and simple creatures without any skills.
Fuzzing in the Large – Generating Software Tests
Well some cards can create additional (potentially infinite) game pieces or resources with which to preform more actions per round.
The benchmark game puts c, rust, and c++, in that order, roughly on par in performance, with go being about 2-3x slower. No idea if that's accurate. Sampling bias means people who like performance are optimizing the languages used for performance, and people who just like to get something working quit after the first benchmark in go or python is finished.

40 years ago, when I started my interest in porn, it was... different. Both in availability and in "potentness".

Skip forward 40 years, I have a bunch of millennial kids. Their (for me discoverable) sexual encounters are extremely limited in comparison to mine and that of my wife, at that age.

Personally I do not think that the one (porn) has much to do with the other (limited). What I suspect is far more the lack of privacy and anonymity. Everyone in their age group seems afraid of the potential flack they will receive “when people find out I did X with Y”. And with the current over connectivity that seems a real possibility.

Whereas we, between 15 and 25, could disappear for a couple of hours / days, and the lamest excuse would enable you to get away with anything.

I truly do not envy this generation. It seems growing up, as in establishing your own personality and experiences, is so much harder.

One factor is how simple it is to use an efficient data-structure in Rust vs C due to good polymorphism and easy dependency management. In C, importing and using an efficient data structure can be a chore, and so many implementations use suboptimal but more C-friendly structures instead.
That was an accurate statement in, say, 1994 but boy did it diverge. Though now they've published a D&D book based on an MTG specific setting so I suppose they could converge again.

It's an interesting project from a heritage point of view, but it feels like a throwback from when Havana was simply the playground of rich Americans. I wonder if this is a history residents really want to go back to? Having said that, I suppose a lot of retro fashions call back to a past that was darker in some respect, but people rarely care.
