Tell HN: Happy Fathers Day

113•consumer451•1h ago
My shortened story: due to factors in Soviet controlled Poland, my uncle played my dad role.

He took me to a quarry to fire Estes-style rocket cars, and all that.. he also managed to steal a Milicja (military police) siren from work, and put it on the back of my banana style bike. As an EE, he made it actually function.

Thanks to all the hackers who made us who we are.

I don't care about 90% of the posts on this site, but enough are relevant to make it worthwhile.

It'd be silly to reply to the threads that don't interest me.

Outside of Towel Day, I'm not sure there is a universally celebrated holiday.

Thank you! My boys are 14 and 16 and I owe virtually all of my joy and success to being a father, husband, and the work required for each.

Congratulations! I assume that you have been a huge nerd with them... please continue doing nerdy things with your kids!
postalcoder•1h ago
if i had to tell younger fathers one piece of unsolicited advice: buy arch support for your shoes. Plantar fasciitis seems to creep up on a lot of dudes after they have kids. It's also the worst.

I love to carry my kid but sprinting around while carrying the extra load did a number on the feet. You can largely prevent it just by spending $50 on a proper insole.

My kid is my favorite thing in my life. So tiring, so rewarding. And after a year of wincing walking barefoot, I can finally run again. Don't lose running time with your kid, buy insoles.

Happy fathers day.

New flex: i use arch support btw
glitchcrab•30m ago
As a father who is suffering from plantar fascitis (brought on by running), I would rather fix the problem by strengthening my arches than mask it by buying inner soles.
delichon•17m ago
Agree. I was able to fix mine by wearing thin sole shoes and walking regularly on rocky terrain. See Born To Run.

I find compression helps at least as much as support for my plantar fasciitis.

I'd recommend something like the links below for going barefoot:

https://copperfitusa.com/collections/feet/products/arch-reli...

https://www.drscholls.com/products/plantar-fasciitis-achy-fe...

I think both companies make a compression band without a cushion, so it won't interference with your insole. (I use 3" elastic sewn in a loop, costs about $1 for a pair.)

Good anti-fatigue mats for anywhere you stand a lot are great as well.

As HN sits at the intersection of business and technology, I will share that I received one of the best corporate yet human Fathers Day messages I’ve seen today from a founder of Brunt (a work wear boot and apparel company whose boots I wear for my DIY projects). I felt an urge to share it but I only interact on HN theses days.

It resonates with me and if you’ve grown a business while raising a family I think it hits more authentic than anything else I’ve seen.

Happy Father’s Day fellas!

Subject:

A Note from the Founder: Happy Father’s Day

Body:

[image of middle aged founder sitting with 2 sons on a tailgate]

My boys and I wanted to wish all the Dads out there a Happy Father's Day.

This year is a special one for me. It's the first year both of my sons can officially wear a pair of BRUNT boots.

Now, my youngest is technically a full size too small for his to actually fit. But he doesn't care, he puts them on and wears them proudly. Seeing them both running around the yard in the gear I've poured my entire soul into changes everything. It puts the last few years of literal blood, sweat, and tears right into perspective.

Knowing there are millions of you out there lacing up our gear every single day - many of whom are Dads - ties Father's Day all together. It connects my why - from my customers, straight back to my sons.

So today, I didn't want to just send you some generic corporate holiday greeting. I want you to know I feel what you feel. I understand the daily grind. I know the toll of the early mornings, the quiet sacrifices, and the heavy guilt we carry when the job takes us away from the people we love.

If this note resonates with you, it's a clear sign that you aren't just a Dad.

You're a great one. Happy Father's Day from my boys and I to you and yours. Enjoy it.

You've damn sure earned it.

En Giroard Eric Girouard, Founder & CEO
