mdoliwa··on 65% of Hacker News posts have negative sentiment, and they outperform
I wonder how HN front page would look like with positive ones only.
mdoliwa··on Build a minimal decorator with Ruby in 30 minutes
yeah, so basically 1 we have available places, 0 we do not.

so this just says if we have free places or not? students.size < maximum_number_of_students
mdoliwa··on Show HN: Show HN: NameIgniter – Simple .com domain name suggestion tool
I created this tool for myself because I always start my projects by buying a domain name. The other similar tools I used often gave me false positives, so I decided to do something about it. I hope it will save you some time.
mdoliwa··on Show HN: ChaosPixels: Collaborative Website Building Experiment
No, I believe it was some kind of science paper.
mdoliwa··on Electrolyzer efficiently converts CO2 into renewable propane fuel
Stupid question, if we find a commercially viable way of converting CO2 into fuel is there a danger of "global cooling" because people will get too greedy with this?
mdoliwa··on LazyVim
I'm Ruby developer, and tried multiple times to switch to vscode or one of these heavy IDE like plugins. All the time I'm back to my simple setup which is basically vim + fzf(powered by ripgrep). CTRL+P I run fzf to find files, CTRL+F to scan files content. It's so fast, that every time I'm doing the test switch to another tool, I'm missing this speed and get back to it. Some time ago I wrote an article for company that I used to work for, describing my workflow: https://thecodest.co/blog/rails-development-with-tmux-vim-fz... you can check it for more details.
mdoliwa··on Show HN: Playcells.com – simple game based on Game of Life
I thought only people knowing game of life will play it, so I didn't explain it. The way they transition is exactly the same as in original game of life. The only difference is this grey dead cells area, where cells are always dead no matter what's their neighborhood. Anyway, I think you're right, I'll add this info. Thanks.

Author here. Maybe it's too early to post it here, as I'd like to add few more things, but I couldn't wait :). There is one board per day, so if you're bored with today's grid please wait for tomorrow. Stack: Rails + Stimulus, no AI :)
mdoliwa··on Show HN: IndieFeeds.com, HN clone where submissions come from personal websites
I added it already.
mdoliwa··on Show HN: IndieFeeds.com, HN clone where submissions come from personal websites
I'd like it to be something on its own, and it's exactly like you said HN is only a method to jump start.
mdoliwa··on Show HN: IndieFeeds.com, HN clone where submissions come from personal websites
Good question, and I'm not sure what's the correct answer for this. Sometimes you just want to build something. I guess my main motivation was nostalgia for the times when I first discovered Internet (late 90s) and I remember it as a network of personal sites, usenet and irc :) Besides that I thought it's something people here on HN would like.
mdoliwa··on Show HN: IndieFeeds.com, HN clone where submissions come from personal websites
Not sure where I found it, but I have it coded like this:

scope :ranked, -> { select('posts.*, ((posts.upvotes_count + 1) / POWER(EXTRACT(EPOCH FROM (NOW() - posts.published_at)), 1.8)) AS rank').order('rank DESC') }

mdoliwa··on Show HN: IndieFeeds.com, HN clone where submissions come from personal websites
yep, that's correct, in most cases I visit about page and see if it's single person's site.
mdoliwa··on Show HN: IndieFeeds.com, HN clone where submissions come from personal websites
Hi, IndieFeeds is a HN clone, where submissions come from personal websites only. For now I add feeds manually while reading HN. If I see submission coming from personal website I check if it uses RSS and in case it does, I add it to IndieFeeds.com. So now HN works as a filter of content for IndieFeeds :). Site is probably lacking some functionality, but for now I wanted to share it with you and see what you think about this idea.

Besides that I love concept of RSS, so wanted to play with it :)

mdoliwa··on Pangolin – Mobile AMD laptop with Ryzen CPU and Radeon graphics
How does it compare to Lenovo Thinkpad L15? As I understand there is no problem with running latest Linux on it, and currently I'm thinking about buying it (mostly Rails development + docker). Do you recommend any other machine?

mdoliwa··on How to Run a Live Coding Stream on Twitch Using OBS
What do you think about running live coding stream on YT vs Twitch? I'm about to start streaming myself, but not sure what platform should I use. Last time I checked Twitch it looked a little bit overwhelming.
mdoliwa··on Ask HN: What did you make during lockdown?
Still work in progress, but I started identifying local flowers https://mdoliwa.com/projects/plants.html I'm using plantnet app to help me with it.

It's super cool and I recommend it to everyone. I feel like I'm treasure hunting every time I go for a walk now :)

mdoliwa··on Show HN: ScanSpider.com – find discussions and related webpages for given url
Yeah, I dont count one comment as a discussion, check now and this thread will show up.
mdoliwa··on Show HN: ScanSpider.com – find discussions and related webpages for given url
OP here.

It's tool to help find resources related to subject of your interest.

If you read some interesting article and would love to explore this subject (to write article about it or because you're just curious) you paste it to ScanSpider and it will scan Reddit and HackerNews, find discussions about it and extract webpages mentioned in these discussions to read more.

What do you think about this idea? I thought it could be great tool for journalists to collect information about given subject and context in which people are talking about it.

Do you see any other groups that could use something like this?

mdoliwa··on Show HN: Refjar.com – find online discussions for your Pocket articles
Hi, I'm creator of Refjar.

Three months ago I submitted it to HN as a bookmarking tool with feature of finding online discussions for bookmarked items. It was on a HN homepage for a while, I got some feedback, but at the end people didn't use it. Neither did I, as I prefer saving articles to my Pocket account.

I decided to rewrite it just to be a simple tool. You connect it with your Pocket account and any time you add a link to Pocket, it tries to find discussions for it (on HN and Reddit). If it finds any, it sends them to your Pocket account with "Discussions" tag.

Let me know what do you think about it.

If you're interested here is my first Show HN post: https://news.ycombinator.com/item?id=16984532

mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
Update: That has been fixed already.
mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
Yeah, I think in future I will decouple these two and extract this feature as a stand alone service.
mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
Yep, I'm thinking about doing some aggregate top links and option to subscribe to lists.
mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
Thanks for info, I'll fix this.
mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
Now it rescans only number of comments. It starts with n = 15 minutes and schedules next scan in n*2 if there were no new comments or n/2 if there were any.

Fetching new discussions after initial scan is in my todo list.

mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
I used Pocket only, and main way of using it was to discover new things. As I love reading comments it was little annoying to find interesting article and have no information about online discussions about it. Besides that I wanted it to have options to share lists of links by making them public, so my wife could eaisly share her cooking recipies :)
mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
Thanks, I know this project is a little buggy, I'll work as fast as I can to fix them. Finishing tags edition, and searching like on stackoverflow is one of the things in my "next" board in Trello :)
mdoliwa··on Show HN: Refjar.com – bookmark links and fetch online discussions
Don't know when and how, but I'd love to make it some kind of lifestyle business.

I have it on my todo list, and it could probably be some kind of premium option, I haven't decided yet.
