Ask HN: Creating a user-generated review site. Thoughts?
I am building a site where users from a niche demographic can review products and services targeted at them. Businesses, in turn, can claim their page, respond to reviews and manage their reputation.

I'm just starting and would really welcome any insights, advice and or reactions on the points below. Most of what I hear is that by getting into this I'm facing an uphill battle bigger than the one faced by most product/service based startups. :)

1. Solving the chicken-and-egg problems that review sites face (similar to marketplaces). I thought I could build a directory of products and services and the proceed to attract users/reviewers. Lastly, I would contact businesses to 'claim' their product site.

2. Possible revenue models for such a platform. I'm considering keyword-based ads (without collecting private info) and charging businesses to add features to their individual product sites.

3. How to determine product/market fit. This seems 'easier' with a concrete product or service, but not so much with a review platform. I guess marketplaces face the same problem. Struggling here.

Thank you.
Cogito ergo sum is itself logic, but it doesn’t depend on logic for the “cogito” part. In more current, trendy terminology (with worse grammar) be rephrased as “qualia ergo sum” — the experience of qualia proves that there is something experiencing it.
The main reason the leaf had bad degradation was the 24kwh battery size. People charged them to 100%, drove a good portion of their capacity each day, and cycled the battery often.

In comparison, a tesla could charge to 80%, never drain to below 20%, and charge weekly instead of daily.

Other analysts differ on whether these things will impact the retail price. But you make my point for me: this is an extremely complex problem, and making any simple assumption about future price is a mistake.
It's a dual problem IMO- women are dismissed due to unconscious bias sometimes I'm sure, but I also suspect there are medical issues out there that are much more common in women that have been so under-researched that we know basically nothing about them. Which does make it a hard problem for front line doctors.
Don't want to give a political opinion as people are entitled to their own. But as a religious fact, it is prohibited in Islam to show veneration of any kind to pagan traditions or celebrations because of its strict commitment to monotheism. So, bringing in salafists into this to show this is an extreme position is factually incorrect.

Heh, I guess this is a difference in perspectives. ML has some really shoddy datasets, like really bad, worse than you think I mean.

> The macro-averaged results show that the ratio of correct samples (“C”) ranges from 24% to 87%, with a large variance across the five audited datasets. Particularly severe problems were found in CCAligned and WikiMatrix, with 44 of the 65 languages that we audited for CCAligned containing under 50% correct sentences, and 19 of the 20 in WikiMatrix.
In total, 15 of the 205 language specific samples (7.3%) contained not a single correct sentence.

In the face of stuff like that, a 90+% correct dataset doesn't seem like a big deal.
It's the standard pattern of corporate activism, dividing people into groups and encouraging them battle one another. The outraged people demand more oppression on the other group to level the playing field, and invent justifications like how it would be economically sensible to make longtime residents move out of their family homes by raising the taxes to reflect an imagined paper asset valuation - in other words even if you own your home outright, you still shouldn't be able to escape the economic treadmill (the crab bucket mentality in action). The people in the crosshairs then have to fight back to keep what they have, while the corporations escape most scrutiny. When the conflict boils over to the point where a law might be passed, the corporations pay off the politicians to grant them an exception, and continue unhindered.

Heck, our whole system is set up this way. For example why is it even taken as some given that property taxes need to continually go up in the first place?! The setup has been made big enough such that most people won't work to understand the whole thing to critique it, instead giving up to focus on the individual actors they most strongly perceive. The overall situation becomes "nobody's fault" and just the way things are - oppression by construction while us plebs fight over scraps.

A joke can be funny and disagree with your beliefs if the fact that it disagrees with them is the basis of the joke. Most shock humor is meant to work this way: it's funny because it's completely inappropriate and violating social norms.

The problem with shock humor is that it can still be funny to people who agree with it and can help normalizing the views it's meant to make fun of. You can see this play out in real time on websites like 4chan that always shift from "transgressive humor" to genuine far-right talking points.

If the joke is "women are bad drivers", you either have to agree with the premise (so the joke is likely about the humorously exaggerated extent to which this is confirmed by an anecdote), or the joke is that someone holds this view while presenting evidence to the contrary (so the joke is that the character doesn't understand he's wrong), or the joke is that the view is extremely inappropriate and doesn't follow at all from what is laid out before (so the joke is that the character is so absurdly bigoted they just bring up their prejudices all the time).

Examples for the three structures would be:

1. <statement that Egypt now has a female captain> <statement that the Suez Canal was blocked by a massive ship>

2. <statement about female drivers presenting them positively> (optional: <statement about one minor data point that could be construed negatively>) <assertion that women are bad drivers>

3. <statement about some scenario involving a woman that could be a strained analogy for driving a vehicle> <assertion that women are bad drivers>

There are probably a few more of these patterns, but they still work by presenting a position that either agrees with your views, follows logically from them or intentionally contradicts them.
Thanks for the thoughtful reply. The breakeven analysis is good!
"I can only think that modern front end development has failed"

I think web devs have no real incentive to improve their front end since search engines don't stimulate and reward them to do so.

Ranking algorithms are blackbox but you can notice that popularity is more important than quality of content so eventually web gets bloated and you end up in information overload.

Okay, so for "The disastrous decision to share a currency", it seems that this argument is coming a lot in exchanges i have, and always with the same kind of people: those that either don't know about economy at all (because, let's face it, its not really interesting except for nerds like me), or those at the dunning-Kruger peak in macroeconomy.

You should read about ECU and ERM, and research speculative currency attack and how much money it cost England and Norway every year. There was a good reason for the Euro, especially for smaller countries in Europe.
The more time goes on, the more we'll know about these questions. Right now there is just no way to know what happens 1+ year after vaccination, since nobody has been vaccinated this long yet.

If I were you I would see the vaccine as a "booster shot" for whatever natural immunity you may still have, with the expectation that it will improve and prolong your immunity.
Humans produce the vast majority of food we eat.

If we stopped that, and just consumed the food that nature spontaneously produces, it supports maybe 50M people. So first you'd have to kill 7000M people.

Even after that, I don't know how you'd stop people from reinventing agriculture.

So on balance, I recommend against this :)
One of the variety languages I used in my CS undergrad in the late 1980s. From what I remember this included at least PL/1, 6809 assembly, C, Pascal, Fortran, Modula-2, and Scheme.
Bit late to the party, but if anything this pricing makes me nervous that you won't be sustainable as a business (ie; pricing is too low, leaves you vulnerable to a few customers costing you way more than they pay).

In particular, I'm nervous that you could get charged through the nose for bandwidth from people who make absurdly too many DB calls or have an insane number of simulconnected realtime channels.

I'd much rather see limits that seem to me "functionally unlimited" than the world "unlimited" which means to me "there is a limit but we won't tell you what it is". Maybe you just have sane rate limits documented somewhere else which would probably do the trick.

It's also slightly unclear what timeframe the billing is for these (I assume $0.125/GB/mo for storage, 200GB storage transfer limit per... day?)
> The vaccines are new but they're not experimental. They have been through the standard trials and statistical analyses.

Not the full spectrum, the trials are still ongoing. That’s why they have, in the US (and the equivalent in many other jurisdictions) Emergency Use Authorizations, not regular approvals.

For me it failed mostly because the complexity involved. Even a rather simple interactive website requires weeks/months of coding & testing. WYSIWYG editors don't cut it, and we need to implement same things over and over again (i.e login).

And yet the Investigatory Powers Act[1] passed into law in the UK and has never been repealed.

We haven't seen a headline like "local ambulance chief spied on my wife's porn browsing habits" so far but I do wonder if there have been any abuses by now?

[1] That's the law which allows people like your local fire chief or food standards agency to download a copy of your browsing history without a warrant. From the legislation itself, here are the surprisingly large list of people:

Getting a warrant in the UK is not some huge effort, in the worst cases it can take just under 1 month but regularly can be under 35 minutes.
>I am surprised Waymo did not try to target this market first as its a lot lower risk and easier to pull off.

Probably the same reason Google kills projects if they don't become a giant market leading success quickly. At Google/Alphabet's current scale a moderate win is not worth pursuing.
The original arrogance is believing that you know which problem is most valuable to solve. Yes, the constant cycle is annoying but framework producers are under the same incentives as those delivering applications. There's only so much runway and at the end of the day you need something useful if anyone will adopt in slightly more useful than switching cost if you want anyone to change to your framework from another. From each attempt we gain insight and perspective that we can use to feed in to a slightly better implementation on the next tool or implementation.

What would CloudFlare automatically check the Host header against? The Host header would be set to the attacker's domain (which is in CloudFlare) and, per OP, CloudFlare does not verify ownership of the origin server IP.

It would be a nice feature if CloudFlare customers could opt-in for origin server IP verification. Once the origin IP is verified, it would prevent other CloudFlare users from using the IP as their own origin. However, I understand why CloudFlare doesn't verify origin IPs -- it would require a verification process that doesn't rely solely on uploading a verification file to a web accessible directory. It'd be a bit difficult to keep the verification process simple for end-users if they aren't running a web server. Or maybe I'm wrong and non-HTTP use cases don't need to be considered and a verification file uploaded to a web accessible folder would work fine.
As a recent example : Substack is worse than Wordpress.
And it's probably related that you can read Wordpress comments with JavaScript disabled, while not Substack comments.
Well, this campaign was inevitable. It’s the global social credit system, just like Adam Curry said. Yikes!
The thing is, this can be disabled A) per thread, and B) can't leak from other processes (it's flushed on each context switch).

So really, we want certain processes with software based sandboxing -- e.g. Javascript interpreters-- to turn this off.
Your experience of using Haskell is that it causes more bugs than less abstract languages?
Not all websites want to be scraped even by search engines, and some only want to be scraped by search engines. Unwanted scrapers may refuse to follow robots.txt or do things with the scraped data that is either undesired to their business model or possibly even illegal, though that is complex. The point is, for better or worse, as far as I know, websites have the right to block scrapers while allowing search engines, and as long as it remains viable to prevent scraping, it remains likely that sites intending to do this will end up blocking or obstructing Tor traffic. Is it a good thing? I would argue it’s too abstract to judge in such a generalized fashion. Whether or not it is a good thing or a bad thing, though, is not important. It is the world we live in right now.
Why not FIX how an SSN can be used? It was not created for this purpose but that doesn't mean how we use it can't be fixed.

Any time someone attempts to use your SSN to identify themselves as you, you should be notified and your authorization should be required for that use to be allowed.

And the higher the value of the authorization, the more care should be required.

Companies are able to do this already with 2 factor authentication. And I think we SORT of have that for change of address, as the Post Office both requires ID and notifies you by mail. Maybe that's really just one factor.

Allow people to require as many additional factors as they want. Confirming my identity in 6 ways when I decide to sell my house sounds good. 4 ways when I buy a car. One or none is fine when I make a $10 purchase. Let me decide.

And let them CHOOSE what organization manages authentication. A private company might do the job a lot more effectively than the Post Office.

Add human methods too. A call from a sibling or child might be one people could set up. Require validation by a notary public.
I think it'll have to wait until a non-surgical BCI gets decent performance. The study in the article uses implanted electrodes - forced surgery would be a nightmare.
>Everyone needs to mitigate every vulnerability

This is definitely not true, or at least needs a LOT more nuance. All security is an economic equation and involves tradeoffs of costs and benefits, the value of what's being defended vs relevant threat scenarios. A cloud service provider allowing customers to run arbitrary workloads side by side on the same hardware virtualized? Yeah, they need to pay a lot of attention. A stateless high performance cluster running exclusively vetted, authorized and tuned workloads with no direct net access at all (possibly even air gapped)? Only if it doesn't have any sort of negative performance impact. Etc up and down the spectrum.

We're fortunate in software that most vulnerabilities have absolutely zero down side to fixing, they're purely bugs. Or an algorithm no longer considered sufficient that has drop in replacement ones that are superior in every respect. But with some of these hardware issues there can be real tradeoffs in performance/energy usage vs risk.

And you can't just say "It will definitely be used in an attack in the future" for everybody, because the conditions to use it are fairly strict. Not everything is "receive a packet from the internet, get pwned". For some systems, any ability for any arbitrary unauthorized/signed code to run is already game over. For other systems, there simply isn't anything valuable to take, the value is the continuous processing done over long periods and the results will be public. If someone notices it's slowing down due to an attacker trying to run their own code it'll just get nuked and paved with an investigation of how they got in.
modern front end development is very prone to producing shit. and it can happen in a very short time, not in years. If user experience and performance are still important to you, you can do good things. But if your only concern is to try new things and mess with your application, the end will be producing shit.
Yeah, so basically that sly clause in contract makes no difference, the problem is you have to go that path yourself, wasting your time, or pay the lawyer, wasting money upfront.

2. It was written by Lennart Poettering, who also wrote pulseaudio and avahi, which are regarded by some as overcomplicated , buggy and hard to port and maintain.
It's even worse than that. You can create a holding company for the building, then just sell the company. Since there's no sale of the property itself, the property taxes are locked in forever at a low rate.

I think part of this is because there is a group of people that doesn’t want there to be an easy technical solution to climate change. They would rather use the massive threat of climate change as the catalyst for social, economic, and behavioral change. They view climate change mitigation tech that does not require changes in behavior much as religious conservatives viewed birth control and condoms - a technical hack to get around immoral behavior.

This is false, energy efficiencies do decrease energy use, in most situations. Jevon's paradox is the exception, not the rule.

For example, increasing fuel efficiency of cars does decrease energy use, because fuel cost is not the limiting factor foe most car travel. Similarly, more efficient lighting, more efficient home space heating and water heating, and better weatherization of homes, all increase energy efficiency and decrease energy use.

There's only so much lighting I would ever want to use, only so much heat, only so much time I want to spend in a car. Energy efficiency is one of the most powerful tools we have to reduce pollution, because it makes all the other things easier.
A couple other notes:

* The IP address 2a06:98c0:3600::103, mentioned in the article as appearing in the CF-Connecting-IP header, is a special IP address that is used for all cross-zone requests that come from Workers. This is not the actual address of any Cloudflare machine. Workers fundamentally don't have distinct IP addresses. Instead, the CF-Worker header needs to be used to identify which worker sent the request. We intentionally do not identify the original client's IP here because the Worker itself could be working against the client, and could have maliciously modified their request to be something entirely different. Hence, the request can't be considered to have come from the original client.

* Any cloud service that lets you make HTTP requests can, obviously, be used to set up a proxy that hides your IP address. Workers is actually less useful for this compared to many other cloud hosts since we tag all outgoing HTTP requests from a Worker with the sender's domain name (in the CF-Worker header), which makes it relatively easier to track, report, and block abuse.
