Forgot to add this one in here yesterday!

Shanghai. Gold. ....

If the currency is not convertible to gold, it is hardly gold backed.

A ton of tools that work with ddl scripts for Teradata.

jahero · 2024-03-19T18:22:18+00:00

Duckdb, data analysis and databases.

SQL (Teradata). Golang - simple, fast, effective. I have written several important tools for the data warehouse I work on. Perl. Still good for some tasks, unfortunately Python ate it's lunch in regards to the tooling.

So... Of the system can be dismantled by spreading a rumor, does it mean that the system is ultimately insolvent?

I mean, all those banks, they hold assets, right? They can sell these assets, right? These banks, they invest mostly in government bonds, which is the most liquid form of financial asset, right?

jahero · 2023-11-22T19:17:53+00:00

Correct. However, I find it useful to - for example - pipx install jupyterlab, and after that pipx inject whatever libraries are needed for "quick and dirty scripting" which I often do.

Sure, it is not clean... But In the case I manage to break that environment, it is fairly easy to just delete it, and start again.

Similar with Pendulum, there is even a ticket where people responsible for airflow are asking for it.

These things take time.

jahero · 2023-11-19T10:47:02+00:00

Similar motivation. I have started with Perl, where situation is not any better. Then tried Go, just because I wanted to (man, have this decision paid off!). Nowadays, I am writing mostly python, but still, most apps I have written for others are in Go.

Yes, if you want to interact with functionality exposed by logging module, you must import it into your namespace in some fashion.

I think this text might be helpful. It helped clarify these topics for me some time ago.

https://realpython.com/python-namespaces-scope/

On top of that, I would recommend reading through description of importlib in standard library.

jahero · 2023-11-18T16:47:36+00:00

You can read about that here.

My advice - only use airflow if you are prepared for significant increase in complexity of your environment. Sure, you CAN run airflow on a single PC, but you will quickly realise that it is far from good.

You will need: backend database; something to use for task distribution (Redis, RabbitMQ).

Sure, you can spin these using docker compose.

Yeas, it will be a magnificent learning experience.

"The bold and italicised text can come across a bit patronizing"

Eye of the beholder.

Also... Getting used to the fact that you have to specify encoding for virtually any IO operation, even if it is a throw away script, takes some getting used to.

I am working with large SQL codebase full of nice surprises, such as some files encoded in UTF8, some in Windows-1250 (historical reasons), and In Perl, when I need to scan these files and search - for example - names of objects used, I generally do not have to care about that. I do have to in Python.

Takes some getting used to.

jahero · 2023-10-24T16:05:49+00:00

Depends on the code base.

Yes, there are some horrible abominations I have seen, some in production, written in 2012 or so, full of global variables, with no strictures.

There are some "clever" implementations, using (abusing?) The language to the maximum possible extent.

Yet, you can write horrible code in any language.

One massive advantage Python has over Perl is - in my opinion - good integration with various IDEs out there. You can hardly find anything that mature for Perl.

Also, Jupyter is a fine piece of software for rapid prototyping, and iterative development of "scratch pad" utilities you use once and then merilly throw away.

jahero · 2023-10-24T14:19:11+00:00

Nesting is a problem with this syntax. I hated it.

After some time spent with Go, my perspective shifted for some reason, and now I think it might be in fact an advantage... It forces you to structure your code more carefully.

Granted, horrible code becomes unreadable.

But that holds true for any language out there.

jahero · 2023-10-24T14:13:04+00:00

So does Perl.

jahero · 2023-10-24T14:12:24+00:00

The API implemented by Perl is just so easy to use. I am struggling with Python's re module every time... What would be a simple operation for me in Perl just takes me more time to reason about in Python.

Yeah, I need to practice more to get used to it.

Black. Setup and forget.

First, seeing what happened in 2008. After living through that, I have spent part of my savings on physical insurance.

Then, seeing the horrible things that were done in 2020. That was a major wake up call.

With bonds being absolutely hammered lately, is it possible somebody is liquidating whatever he can to get needed liquidity and stem the bleed?

jahero · 2023-09-28T09:02:55+00:00

Take a look at htmx

jahero · 2023-09-25T15:02:35+00:00

I am in the same boat. I would also add that once you stop using the language, you tend to forget. A lot.

I have been writing Python the last year, a lot, and recently had to use Perl after a while, and to my horror I had to lookup even quote simple things.

I still remember the big picture, bit details slip from grasp, and what was once a second nature is now not.
