Nice write up!

After a couple of attempts I settled on a a different approach for my old Kobo.

It can connect to Dropbox so I deployed a small app in Fly.io which takes a link, bundles it as an epub and uploads to the right folder. Day-to-day all I use is a bookmarklet

Author here, thanks for posting this!

If anyone has any feedback, questions, or any additional examples of deep/shallow abstractions they've used recently, let me know!

Regarding the culture bit: I feel that Erin Meyer's "The Culture Map" [1] should be high on any reading list around how to work in a remote environment, especially as a manager. Of course, every individual is different and not everything needs to be taken at face value, but it provides a nice framework to think about how/why other teammates may approach situations in a specific way.

New comment by tpaschalis in "Ask HN: Which books you have read till now that were worth investing time in?"

I'd have to agree. I personally found that the book's structure with the themed chapters doesn't lend itself to a continuous reading; but going in small chunks as the authors intended, the commentaries felt a tad better.

- So Good They Can't Ignore You. Even though kinda 'self-help'-ish and repetitive at times, it played a role in shaping the way that I think about my career.

- The Daily Stoic. A collection of snippets from stoic philosophers, tied with examples from modern living, it was a good and lightweight introduction to philosophy.

One thing to try might be contributing to Open Source?

Choose a project that looks interesting to you (ideally with a large community and modern tech stack) and join their Slack/Discord/Mailing List. You'll need to be patient and humble and it's going to take a while until you feel really comfortable, but read a lot, ask questions and try to contribute small bits here and there.

This will put you in touch with many interesting and experienced people, plus it's usually a great learning experience.

If anyone is interested, I've also published a Go implementation [1] of the code for float64 slices.

Results seem to exactly match the R and Python implementation, so there will be a second pass focusing on performance, stability and support for categorical variables.

Come on, no offence, but you sound like astroturfing.

I have no idea how you may be aware of a company's internal information, but the greek article you linked does _not_ mention rating system names.

Also, but when using e-food there's no way to actually rate delivery people, only restaurants (like you claim above with "Negative reviews from customers...").

+1. I couldn't get it to understand the partial derivative symbol ∂, unless it was drawn in a very specific way.

But really cool idea, name and execution!

Thanks for bringing back fond memories of playing Far Cry 2 LAN multiplayer in run-down internet cafes back in middle/high school. :)

In case you haven't played Far Cry 2 before, here's [1] a great video that showcases the aesthetic choices and art direction behind the game, and how they all fit together. Also [2] showcases the amount of detail that went into making FC2, that isn't always found in more modern games.

This comment has produced one of the geekiest t-shirts of all time.

In [1] Brian Kernighan interviews Ken Thompson, who's wearing a t-shirt which contains the relevant snippet along with a comment "ΕΠΙΤΕΛΟΥΣ ΤΟ ΚΑΤΑΛΑΒΑ!" (greek for 'I finally understood it!').

New comment by tpaschalis in "Ask HN: How do you organise your files and folders?"

tpaschalis — Thu, 04 Jun 2020 11:53:13 +0000

Great ideas all around here, definitely stealing some!

Personally, there was a time where I grew a little fond of numeric-based naming. It allowed for quickly tabbing between directories, easy separation and predictable ordering (eg. 1xx is for clientA, 2xx for clientB, 9xx is for miscellaneous files etc).

Fun story of how that came up; at some large project they were using Sharepoint for everything. From specification documents, to invoices, to code backups and JAR files.

I never figured out whether it was Sharepoint translating for different locales or people using Windows machines different languages, you'd get things like "My Documents", "Mes documents" "Τά Έγγραφα Μου" and "Eigene Dokumente" all mangled up together, which was a nightmare to navigate in, both in speed and understanding, so the this numeric-based naming was an attempt to put some order to that chaos.

New comment by tpaschalis in "Ask HN: Software for producing terminal-based tutorials?"

tpaschalis — Wed, 27 May 2020 15:04:02 +0000

Since you mentioned terminal-based tutorials, here's a terminal-based solution.

Most linux systems should include script [1] and scriptreplay[2], which should suit your needs. Here's a complete example of a recorded/replayed session[3].

On MacOS it should be as easy as `script -r ` to record and `script -p ` to replay. YMMV, but I like it for _small_ use-cases, as it puts simplicity and portability over features.
