5 hours going now and the entire thing is still completely down. This level of incompetence and their total disrespect for their customers is unbelievable.

New comment by molsson in "Show HN: Sharpe Ratio Calculation Tool"

molsson — Sun, 29 Jun 2025 20:30:49 +0000

I guess this is the 1yr sharpe plotted over time, ie the sharpe at date X considers the stddev within the previous 365 days etc?

Many brokers only show 1yr sharpe or perhaps 3yr sharpe (for example swedish nordnet has 1/3/5 year sharpe: https://www.nordnet.se/fonder/lista/jupiter-gold-silver-usd-... )... but very often stocks/funds go steadily upwards for several years in "good times" and then we have major drawdowns during turmoil like 2008 or 2020 etc. In these cases, a 1yr or 3yr sharpe can be very misleading.

Have you considered also plotting 3yr sharpe and 5yr sharpe over time? Perhaps the length of the sharpe ratio would be configurable in the calculator?

process.stdout._handle.setBlocking(true)

...is a bit brutal but works. Draining the stream before exiting also kind of works but there are cases where drain will just permanently block.

async function drain(stream) { return new Promise((resolve) => stream.on('drain', resolve)) }

Hmm, why did you build it as a desktop app in 2022? Seems like a no brainer to have this in the cloud so that you can seamlessly process huge files and integrate with various third-party APIs. I've used https://www.gigasheet.com/ for this before (which is cloud-based). And there is also the open source visidata project.

It would be nice if the web somehow filtered out links that one had decided to not pay for.

We used a similar approach when we pushed to get -Werror enabled in a large C++ code base I worked on years ago.

I hate when you browse through 10-15 websites and for all of them you quickly click the "Accept" button in the bottom banner to get rid of the irritating cookie banners.

And then suddenly, on the 16th website they put a fucking "Buy our thing" button in a bottom bar that you quickly click on without even thinking twice.

New comment by molsson in "Anyone made the jump from MySQL to PostreSQL? It is worth it?"

molsson — Tue, 16 Jul 2019 15:12:56 +0000

I recently migrated a small side project from MySQL to PostgreSQL. I wrote a short blog post about how I did the migration, issues I ran into etc: http://blog.minimum.se/2019/07/09/upgrading-node-mysql-to-po...

I'm overall very happy with the migration and PostgreSQL also ended up taking less memory (RSS) in prod, which was a nice bonus (this is useful for me because I'm running this on a low-end Digital Ocean droplet).

I agree, especially some info on production installation on Linux would be really nice. For example, is it better to install the "postgres" ubuntu distro package, or is it better to install the Ubuntu package provided by postgres themselves at https://www.postgresql.org/download/linux/ubuntu/? Which one of these offer the best security / stability?

The OWASP Postgres hardening page recommends that one removes the default "public" schema in postgres: https://www.owasp.org/index.php/OWASP_Backend_Security_Proje...

...whereas this course seems to use the public schema and just query for "SELECT * IN public.foobar" etc.

I remember being a bit confused about "schemas" when I switched from mysql to postgres. I think it would be good to have a special section that explains what schemas are typically used for, and in particular when/how to use the public schema correctly.

The free "teaser video" starts off showing "actor_id serial NOT NULL" but in postgres 10 and above identity columns can/should be used instead?

The content overview doesn't include anything about escaping data to prevent SQL injection (escaping of literals vs escaping of table/field names etc). This is important to get right and postgres has a slightly different approach compared to mysql and others.

For example, you can and should use parametric queries like:

client.query('INSERT INTO mytable(a) VALUES ($1)', ['hello'])

...but that doesn't work for all types of queries, for example you get an error for:

client.query('SET LOCAL SEED = $1', [someVal])

Another example, you might need to build a dynamic where-clause based on data from an "advanced search" UI query builder, and then you need to make a list of all the "foo = $N" parts (and increment $N as you go), plus another list of the actual variables. Maybe there are some nice tricks / techniques to simplify that?
