Hello, for the moment I keep only titles and summaries, not the full articles. Once the articles become too many (for the moment it's not the case), I will think of some partitioning solutions.

The underlying database is PostgreSQL and it works well under medium load.

Show HN: Lectura, a privacy, simple, server side rendered RSS reader

https://lectura.info/

I am avid reader of blogs (always been since 2005 onwards), so it was always on my list to build a rss reader at some point.Initially I've built lectura for myself (the first version started when I've experimented with server side rendering/Thymeleaf + Spring Boot) and self hosted on a server (without a domain). Then I decided to vibecode multi user support. And this is the final result.What...

Fish and dairy.

I don't avoid fats, just saturated fats.

Kefir, eggs, chicken breast, potatoes, beans, rice, oats, fruits, vegetables, a little olive oil, low fat cheese and raw seeds (pumpkin) or raw nuts.

To be honest making the calories today is easier than not making your calories. Go to any supermaket you have caloric bombs everywhere and in everything.

I've explained why I don't have mayonnaise. Also it was just an example. I avoid it because I can eat more meaningful stuff without bombing my calories and saturated fats stats. The mayonnaise I find in the shops has terrible composition.

If I track the salt, a lot of the salt I need comes already from various types of yoggurts (like ayran, or light cheeses and meat), if you actually track it and scan the barcodes of what you eat, you will find out there's already enough to add more.

I was eating spicy food and it irritated my intestines. I have enough fibers to never get constipated.

In the morning I have boiled eggs, or yoggurt with cereals that don't have sugar, I also add various type of seeds and maybe I have a fruit or two.

At lunch I usually have chicken breast or fish and some carbs (usually rice, or baked potatoes, rarely some simpla pasta). Salads, carrots, tomatoes, cucumbers, cooked vegetables, home made soups.

Then I have smaller meals with more fruits, or yoggurt with less fat. Or soups.

Ok. Maybe it wasn't the best example, but my reason I avoid things like mayonnaise is because they add lots of fats and calories without making me feel full. Most of the commercial mayonnaise, in my part of the world, doesn't have a lot of proteins (even if in theory the eggs should be there), and have lots of saturated fats. So I prefer to fill the calories counter with more meaningful choices. For example I very much prefer having 20g of nuts instead of adding mayonnaise.

All in all. That was an example to make a point. I also don't eat butter.

I've increased the fiber intake from close to nothing to 30g gradually. After a few months into the game the bloating doesn't appear anymore. Also some probiotics can work in the beginning, but usually the best ones are more expensive and the science behind them is disputed.

In my part of the world this is the norm.

The one you find in shops has terrible stats. If you make it at home I guess it's manageable, still it can really bomb your fats stats for the day.
Re:Is "colorectal cancer" rising in "young people"? on Tuesday May 26, 2026 @02:35PM (#48283895)
Yes. Too much sodium, or oil. Or other nasty substances.

Seeing young adults around me going through this made me change my dietary habits 1 year ago. I went to the extreme by modern food industry standards, but now:

- I take 100g proteins, 30g fibers daily

- Red meat once a week but never fried

- Most of the protein comes from eggs, yoggurt, chicken and various plant based sources

- No white bread

- No added sugars, no deserts except fruits

- Nothing fried

- No added salt

- No canned food

- Saturated fats kept at minimum.

- No spicy food

- No alcohol

The results are incredible. I lost 8 kg, my blood samples are perfect, my pulse dropped with 10, I sleep better, no migraines (I had those for years). Also this year I was the only one in the family that didn't got any cold, and that's quite hard with two kids going to kindergarten.

It's hard in the first two weeks, but afterwards it's becoming your daily routine. I also use an app to track various stats. The gameification of the diet also helped me a little.

I urge you to try this. To make it more manageable start small. For example avoid fast food for 2 weeks. Don't put any mayonnaise in your food for 1month. Stop eating white bread. And then add more and more restrictions. The hardest fight is the urge to eat sugar and drink alcohol, give it time.

Fixed.
Re:The Shape of Inequalities on Friday March 20, 2026 @05:50AM (#47452459)
I've fixed that.
Re:The Shape of Inequalities on Thursday March 19, 2026 @02:47PM (#47444021)
Ok. I will add them tomorrow. Also I will fix the first animation (b doesn't grow there as it should).
Re:The Shape of Inequalities on Thursday March 19, 2026 @02:37PM (#47443863)
That's actually a good advice. Does a separate, "static" screenshot also work?
Re:The Shape of Inequalities on Thursday March 19, 2026 @02:10PM (#47443498)
Thanks for spotting this. I've mixed two ideas. Need to comeback to it. The smaller circle has to increase its size as b grows. As it is now it works because o triangle degeneration.

Blog looks promising. Is there a RSS feed associated with it?

My grandfather was a math teacher, and "Gazeta Matematica" was "his life".
Not a garden but I also curtate links that I find interesting here:

Fun fact, in the book Life Of Pi, the kid stays exactly 227 days on the boat with the tiger.
