Ask HN: What are the best resources to learn about performance marketing?
We're in the early stages of experimenting with performance marketing (PPC on Google, Facebook, Instagram etc.) and have been running a few small experiments.

Given we now have baseline figures for what ballpark CTR, CPC and CAC figures could be, we're now trying to figure out what the most effective levers are which we could use to optimise.

If anyone has any thoughts or go-to resources, I'd love to read them!
You need at least a $45,000 car to equal paying uber to drive you everywhere.

The ride share services haven't made a dent in the transportation needs of the world.

You know what's necessary? On demand minibusses that go everywhere and are routed to riders along the route to the destination to keep them full. Uber isn't that.
That wouldn't help. A significant metric Google uses for ranking is relevance, meaning number of historic clicks for a given search term.

As users learn that Reddit links aren't useful sources of information, they'll click less, which means the relevance between the search term and Reddit goes down. Ultimately reducing Reddit's ranking, regardless of if the Googlebot is allowed to index the content.

People often mix up indexing and ranking. Indexing is if you're even in the results set, but ranking is where. Reddit might, technically, still be in the results set but if it isn't on page 1 for a given search it may have well not be.

I'm not sure if you are talking about some local builders you know, or big construction companies in general?

I know lots of people who rent or buy-a-share-in apartment blocks. Each apartment block is owned by a company spun off of the construction company that built it.

Google will figure the higher bounce rate of the page (the user quickly went back to the SERP) means it's not as relevant as they thought, so they'll move it down in the search rankings.

A fantastic tool! Thank you for sharing.

The only drawback is that I cannot see the colors on the UI (on a sample website) like I can with Happy Hues. Granted, I can copy them into my website to test out.

I just love how easy it is to use Happy Hues.

> Consider the average personal car is only in use 5% of the time. People are paying an enormous amount to own, house, and maintain a car that they are barely using.

This statistic is silly. It's like the "you only use 10% of your brain!!1" meme.

I don't disagree with the overall premise and there's definitely cases where it makes sense (especially in cities), but there's a real trade-off being made.
Do we have estimates on how heavy individual dark matter "particles" are? Could the 700g all be in one blob?

But C/C++ is messy because it doesn’t have a language/platform-provided package-management system, while python actually does.

So that’s apples to no oranges, I guess. And it still doesn’t leave python looking particularly good.

the proof if it exists will involve math is the very complicated and abstract and cutting-edge, similar to the proof of Fermat's Last Thereon . It will involve some sort of result, I am guessing, from complex analysis an number theory and then generalized in such a way as to prove this result.

As someone who's been in software development for two the better part of two decades now I would say that's far beyond the truth.

Yes it's not great right now and it's not completely clear if I should recommend a new user pip+venv, pipenv, pyenv, poetry or conda and that's a big problem, Python was actually quite early to handle dependencies and packaging in a standardized and structured way. I remember that most of the projects I worked on early on in my career more or less completely relied on vendoring dependencies, if packaging systems existed they were of either very complex or the one that came with your os/distro.

However Python currently needs to catch up, we need some alignment and a clear path forward, it would also be great to have an official way of building artefacts. There's plenty of ways today but no great blessed way to recommend a newcomer.

> This in turn makes the platforms less useful and more hostile to users and presumably at some point that will cause users to leave the system.

People always seem to brush off this kind of comment when I see it discussed, usually the argument is "well, you're a software developer / superuser, normal people don't care about these things." It will be interesting to see where the breaking point actually is; I've always felt that platform users deserve a little more respect than that. The linked identity thing is especially frustrating for me.

I stopped posting to facebook in 2010 (still using it to keep in touch via messenger and see event invites, and to avoid alienating extended family), but I used to have an instagram account with a fun theme that I only shared with a few friends. What was fun and relatable for my friends was confusing and obtuse to my family. Even the account username was embarrassing in that context. So I always kept them separate, explicitly saying "no, I don't want to attach this to my facebook account." Then one day, it just sort of happened? I can't remember if I was tricked by a dark pattern or if they just forcibly fused the accounts YouTube-Google style, but that day instagram immediately lost all usefulness to me and I haven't been on since. For me as a user, social media has always kind of felt this way.

I'm curious to see what will happen to reddit and its communities, and even more curious to see whether the next generation sees internet anonymity as a cool feature. When I was growing up, it felt like being able to form an alternate identity online was almost the whole point, but I guess back then there were fewer avenues to cultivating your identity as a personal brand for profit.
This is a good question. I have wondered the same thing about software in general. In this specific case, though, there are 313 open issues and 33 pull requests. So people are finding bugs in the current version (and fixing them).

A final "please fork me" commit
I don't get it either... nor do I understand why venv is considered difficult to use.

"It automatically creates and manages a virtualenv for your projects, as well as adds/removes packages from your Pipfile as you install/uninstall packages."

Well, thanks but automate "python -m venv myvenv" ? Add/remove packages from a "Pipfile" ? Do I have to specify dependencies somwhere else than requirements.txt ? Why ?

There must be some use cases I'm not aware of.
If car-sharing is cheaper & more convenient than car ownership, that means the demand is higher for it than private usage, which means that there will be more cars on the road rather than less. A significant majority of the environmental damage a car causes is in it's operation rather than it's creation & disposal, so realize that car sharing and autonomous cars are bad for the environment, not good. As long as the norm is still 1 person per car.

Autonomous raises the prospect of cars driving around with no people in them, doing even more environmental damage and causing even more traffic jams.

interesting discussion a few months ago, https://news.ycombinator.com/item?id=19897987
C/C++'s package management story is "defer it to distributions". Personally I much prefer `apt-get install libfoo-dev` to 1) each language inventing its own incompatible system, and 2) each developer self-publishing, so there's little to no safety or accountability when adding a new dependency.
Alternatively, they could add one of those 1.4k people in to help if they seem to have produced working code for the project prior.
But the Python mess because initially, it didn't have such a system either. Then a bunch of them were introduced, and some of them became official but there was never one that solved all the problems.
Jeez, it seems every time in these threads there's someone who comes in like "Hey I live 40 miles from the nearest paved road, I need my own car!!!"

Nobody is saying it's going to be illegal to own your own personal car or anything. Sure, if you want to live in the middle of nowhere then you'll probably need your own transportation. For a lot of people it's not going to be as necessary to bother owning your own car when you can call one whenever you need it and it will be there in 5 minutes.

If you can get 90% of the flexibility and time for 10% of the cost that is going to make sense for a lot of people. Not owning a car at all is a much larger difference in savings than owning one that gets 30mpg rather than 20mpg.
Yes. And that is confusing, as pip is a de facto standard IMO.
>I am not suggesting that the responsibility falls solely on women or minorities to deal with their own problems at all, but I am suggesting that they should take some agency of their own.

Great idea! Perhaps following your comment, women and minority groups will start to organize to protest against unfair and illegal treatment.
Agreed. MS Combat Flight Sim 2 also hit that sweet spot of "just felt right" that few if any others managed.
Yeah, for a while, Digg and Reddit were very similar, so Digg thought, "Hey, let's differentiate ourselves from our competitors." They then proceeded to ruin themselves by trying to become something more like a news aggregator, when what users really wanted was what Reddit remained.
> Immutable data structures are great, but when it's the default, it's a huge win in cognitive-overhead. Maybe that feature isn't unique to Clojure but it's certainly not a prerequisite to being called a lips or a functional language.

Yes, indeed.

TBH, I developed in Erlang for 10 years and, as a result, developed a strong preference for "immutable data structures everywhere".

Unlike LISPs that I've seen (admittedly not that many), with Erlang there simply is no global data so no vars to change - it's all done via function parameters and tail recursion (Erlang has TCO baked in, btw).
The thing is that law and public acceptable change over time so

It clearly has its faults, but it is simple to use, requires no “venvs”, is CI-friendly and mostly does what it’s supposed to with few surprises.

Much unlike how things work with python.
> no one is allowed to be clean in this game.

That is why corruption is endemic to authoritarian regime. In a state where it is impossible to climb the ladder without accepting bribes and giving them, you make sure everybody and guilty and its easy to do some "clean-up" whenever you need it.

Anti-corruption operations in authoritarian regime is just this, replacing problematic cronies with more faithful ones.

Systemic corruption is a proven mean of control.
LSD has a way of giving one a new perspective. However, it can also make one very suggestive and can amplify any emotion, good or bad. Set and setting is key, and even if the experience feels "bad", there's often some sort of benefit one can derive from that trip, if you approach it with mindfulness.

Psychedelics are not a magic band-aid to fix all your problems. But they can nonetheless change your life for the better, if you approach them right.

I recommend that you study psychedelics intensely before making the decision. LSD may not even be the psychedelic for you. There are also psilocybin mushrooms, as well as N,N-Dimethyltryptamine.
Yes, I believe the key phrase was ”along the lines of” and Tao’s result doesn’t actually prove any particular constant bound which would indeed be a much stronger result.
Pipenv isn't stable and reliable yet though, at least compared to pip+venv. The tooling is really handy and it makes it in theory easier to write Python code, but in practice there is still work to be done.
That's a fair point. I live in embedded world most of the time, and using third party libraries in that space is not always so easy :)
Scraping is not a privacy problem, or Facebook's problem to fix. If users are happy to publish the data, or add the scraper's account as a "friend" (so it can see "friends only" content) then the user is happy for them to have the data.

The main problem with Facebook is how much data they collect by themselves, including data collected by stalking the user (as opposed to data the user willingly posts on the platform).
There are commits, but no release, it's very frustrating if you depend on any of those commits, and there are no one available to cut a new version, or to pass on the torch.

Woah there, the person you're replying to didn't once use the word "weird" or any synonyms thereof.

They said that men and women tend to have different broad interests. But that doesn't preclude women from having an interest in tech. He's making a statement on statistics, not making a value judgement about anybody.
It's not patronizing. We have, e.g., men in nursing conferences (https://www.aamn.org/2019-annual-conference). I don't find that patronizing as a man. It makes sense for a field where men are a minority.
Just curious, you don't find learning entire languages hard or confusing but suddenly writing 3 commands to set up a venv is too 'messy'?

If you have a reddit account and go to the site not logged in the site looks like trash. The articles seem worse than what you see when logged in. Similar to YouTube if you aren't logged in you see the trashiest videos on the "unlogged in" main page.

I don't know if that's on purpose or it's just like that. But there seems to be a big difference in the quality depending on whether you are logged in or not.

As for the reddit site itself I wonder what is the ratio of old.reddit viewers vs reddit viewers are. I've used reddit for over a decade and absolutely hate the new style I only go to old.reddit if that changes and only new reddit is available I'll abandon my account (or sell it to Russians ha!

From what I can tell from reading the article, the established Hollywood studios are mad that Neflix upgraded the experience at their 'press junkets' which are a completely normal part of the promo cycle.

Press junkets are notorious for being rapid-fire grinds that studios consider a necessary evil. I guess the case could be made that by making it a more pleasant experience (and also granting journalists paid set visits is mentioned?) could give them an advantage among critics/voters? Probably but that's the business, just like this WaPo article was probably pitched by a competitor PR firm.
I’m always surprised by the level of employee activism at Google. I mean, it’s a job. You don’t like it, or the company, then the default thing people do is leave. But based on my experience Google is different because they brainwash you into thinking that Google is the second coming of Christ and you don’t want to lose your front seat by just leaving. So instead of moving on, lots of frustrated employees burn out trying to change the company from within.
Yes, kind of like that. Except that it doesn't use requirements.txt but rather a file called Pipfile. In there you can also pin version, or leave them unspecified or only partially specified and you can also divide them in dev-packages and normal packages (so it allows for a bit more flexibility than a requirements.txt file).

Thanks for that Feynman link!

> “If I ask you a question during the lecture, afterwards everybody will be telling me, ‘What are you wasting our time for in the class? We’re trying to learn something. And you’re stopping him by asking a question’.”

In my experience there are almost just 2 types of motivated students: those who want to understand the content of the course and those who want a good grade and ultimately graduate.

There's often a conflict of interest between them. For example the first group wants to learn more, ask more questions, go deeper. The second group sees this as a threat because the additional content may now be on the exam as well. And they often misunderstand this behavior of the first group as just being teacher pleasers/pets.

Or from own experience: when you tell the prof that he accidentally started to cover the same topic that we already covered in the last lecture (because you're there to learn more), you will annoy a lot of people who hoped to get one fewer lectures to study in the course. Less content, less effort, same grade.

You hear the first group having passionate discussions on physics or programming over a beer, while the other group discusses all the latest info of which prof is how demanding, what the grading criteria are, what the deadlines are, which departments you should or should not take courses from, where they have mandatory presence, who does multiple choice tests and who does free-text exams.

I don't have much to conclude, just an observation.
I work in building design in the US and that's not what I've seen here. There are investment companies that finance building / renovating buildings. They might hold onto it until they get it filled with tenants then they sell it to a different investor who runs it. The construction company that does the building is unrelated to either of these. They specialize in construction, which is a completely different skill set from property management.
Which is why I said the feeling may not be justified. But my feelings are what they are. Not being able to explain why I'm feeling them does not invalidate the fact that I do feel them.

You cannot tell me what I'm feeling.
