raphaelj··on Ask HN: Who's looking for a co-founder?
Thanks. I just launched the project last weekend. I'll start reaching studios in the next few days.
raphaelj··on Ask HN: Who's looking for a co-founder?
Hola,

I just launched https://noisycamp.com, an AirBnb for Musicians.

I'm trying to make it easier for music studio owners and musicians to reserve, pay and manage their practice spaces.

I just released the first version of the web app, and I'm starting to reach studio owners to create a base inventory of studios.

I'm looking for someone with strong sales and product skills, able to help me developing the business side of the project.

raphaelj··on 20 months, 2K hours, 200K € lost. A story about resilience and sunk cost fallacy
>> The only valid reasons to choose non-relational databases are scalability and performance.

Agree 200%. And people seem to get a wrong idea of where this argument starts making sense. With the right indexes, I can easily handle 200req/s on my last SaaS running on a $50/m PostgeSQL.

It's also significantly easier to move from a standardized relational model to a document DB than the opposite.

I always find it amusing that PostgreSQL is classified as "boring tech".

I'm using it every day, and I'm always amazed by how wonderful this piece of software is. PgSQL help me doing thinks in seconds that would take days do to in Mongo.

Thanks !

Oh yes... I should work on reducing the size of my Webpack bundle. I'll start reaching rehearsal spaces owner later this week, studios should start adding up!

raphaelj··on Show HN: Airbnb for Musicians
I'm doing a soft launch, and I'll start reaching rehearsal spaces in New Zealand and Australia this week, as these are still open even while we are in a pandemic.

I'll start reaching studios in US and Europe later this year as these places get out of the pandemic.

Hi HN,

I spent the last few months building this service to make it easier for studio owners and for musicians to find and book practice spaces.

The platform is open to professionals, but can also be used by private individuals to monetize their home studio.

Not all exports/imports can be carried in ships. Think about services or fresh food.
raphaelj··on UK and EU agree Brexit trade deal
France's poor handling of the pandemic has way more to do with late measures and poor decisions earlier this year than the number of nurses and MD. More nurses will not make the virus less infectious.

As often, EU is a nice scapegoat.

raphaelj··on New coronavirus variant: What do we know?
Could it still be that this variant is as infectious as others, but just happens to be the dominant one in the regions where the virus circulates the most, for reasons that have nothing to do with the genetics of the virus?

London and the South East are some of the densest populated areas in the UK, and one could expect exponential growth of infections there while other less populated areas could manage to keep their Rt around or bellow zero. If this strain was more prevalent in these regions, you would also see it taking a larger share of the infections nationwide.

However, the precautionary principle has been the keystone of good handling in the pandemic, so they are right to apply precautionary measures before it's too late. We will learn more about this strain in the next few weeks.

raphaelj··on New coronavirus variant: What do we know?
Also, the UK seems to do way more sequencing of the virus than any other country, so one would expect such cherry picking to actually happen in the UK.
raphaelj··on Understanding mRNA Covid-19 vaccines
Is there a reason they don't create the protein in Vito and them inject it as a vaccine? I would imagine they could use in Vito cells to generate a lot of spike proteins.

Are they using mRNA because it's easier to manufacture? Or is the protein too instable?

raphaelj··on Google Cloud: $72,000 bill overnight
I've been super happy with BunnyCDN for my personal SaaS. Their UI is super nice, and it has been super easy to setup. Costs are really easy to predict, which is awesome for me.
raphaelj··on Google Cloud: $72,000 bill overnight
Someone should make a list of all the providers that support some kind of billing budget. It took me way more time than expected to find a CDN that has a budget limit for my personal project (I'm using Bunny CDN)

raphaelj··on Burnt $72k testing Firebase and Cloud Run and almost went bankrupt
It's ever worse for services like AWS Cloudfront.

One of your competitors could just rent a cheap server on OVH with uncapped transfer and incur you $10k in cost in a few hours.

raphaelj··on Burnt $72k testing Firebase and Cloud Run and almost went bankrupt
Some platforms do that: - Heroku costs are pretty predicable, and you can easily set a maximum scalability threshold to their auto-scalable dynos, so that they will never cost you more than a predefined amount of money; - BunnyCDN requires me to top-up their prepaid account, so that I'll never spend more than what I have on that account.

You don't have to immediately delete customer data.

Most service that has a limit cap will have a "grace period" of a couple of days during which the service does not work but the data is not deleted. That give your some time to get notified of the issue, and fix the problem/increase the limit.

raphaelj··on AWS Lambda pricing now per ms
I find it annoying to have all these pricing per second, and now per millisecond. It's really hard for my mind to visualize what `$0.0000000021 per millisec` actually is.

Being billed by the millisecond does not mean that you should give a pricing per millisecond.

I prefer Digital Ocean or Heroku's approach of billing by the second, but giving the price per month. How on hell is `$0.0000000021 per millisec` better than `$5/month, billed by the millisecond`? If I know that my workload will be about 20% of a dedicated CPU, I know that I'll end up paying about $1 per month.

The design is top notch, definitively one of the best simple SaaS UI and UX I've ever seen.
raphaelj··on The Tech Stack of a One-Man SaaS
Hey Anthony,

I really like your product. It's crazy fast, might solve one of my issue, is super simple to use, and the UI is gorgeous.

I've a few questions though:

- how do you compare to other privacy focused analytics tools, such as https://usefathom.com/ or https://simpleanalytics.com/?

- it seems like you just launched your SaaS a couple of weeks ago. Why didn't you launch it earlier by removing some not strictly necessary/MVP features, such as the security login emails, the ability to manage multiple websites, a less scalable but simpler architecture ... ?

- how much time have you spent developing the product? I've been working on my personal SaaS for more than one year, planning to launch it in the next few weeks. I'm still working at my 4/5 full time job, and I really wonder how you managed to deliver this beautiful product while still working fulltime. That would be a wonderful opportunity for blog article BTW.

Great work!

raphaelj··on Virgin Hyperloop Has Invented the World's Crappiest High-Speed Rail
The problem with hyperloop is that is does not solve the main problem of bullet trains: infrastructure costs. Nobody complains about the TGV/Shinkansen/ICE being slow.

Building a new train line cost millions of €/$ per km/mi because you need to expropriate properties, build tunnels and bridges, fine tune the tracks (any small distortion in the tracks will cause significant annoyance for the travelers). Hyperloop will have all these issues, but worse, as the speed is higher, and as the hyperloop trains will not be able to run on existing tracks.

No only suffering from the 2nd world war, but undoubtedly being the hardest hit nation.

It's like being a centralized economy really helps when you have to catch-up a competitor, and when the path to achieve that is very well understood. By contrast, market economies shine when innovation is the driver of growth.
