My wish for the new year: hopefully, AI singularity is still a few years away and doesn't happen in 2025!
;P
Happy perfect square year, everyone. The previous one was 1936 and the next one will be 2116.
1) is a square: 45²
2) is the product of two squares: 9² x 5²
3) is the sum of 3-squares: 40²+ 20²+5²
4) is the sum of cubes of all the single digits: 1³+2³+3³+4³+5³+6³+7³+8³+9³
6) sum of the first 45 odd numbers: 1+3+5+...+89
7) is a Harshad number: https://en.m.wikipedia.org/wiki/Harshad_number
3^2 is the sum of the first three odd numbers. 4^2 is the sum of the first four odd numbers. 5^2 is the sum of the first five odd numbers.
Edit: sorry, don't mean to be a pill.
Obviously all the formula will be equivalent to each other. They are, by construction, all restatements of each other.
Actually, property 5) trivially implies 1) but also 2), as `(1+2+...+n)² = n²(n+1)²/4` and either n or n+1 must be divisible by 2 hence one of the squares divisible by 4 hence it is a product of squares. But also property 4) as `(1+2+...+n)² = 1³+2³+...+n³` (easy to show by induction).
You can prove it by induction; just expand (n(n+1)/2)² – (n(n-1)/2)², the result is n³.
There is no such thing as a Harshad number, there is a _Harshad number in a given base_. All integers between zero and n are n-harshad numbers.
Which is a pity, because apparenty it means the `joy-giver`. I think human kind could use a joy giver year
[x**2 for x in range(32,100) if x**2 // 100 + x**2 % 100 == x]
[2025, 3025, 9801]At the ages of perfect squares is when we all cross or achieve significant milestones in our lives as children, students, (young)adults, spouses, parents, grandparents, senior citizens of society and so on.
This year being a perfect square, I wish that it will be as much or more special as it was for everyone at those ages.
If you multiply your ages… 36^2
And now, looking back 17 years later, I'd say he succeeded. It's the tarsnap founder.
1681: eight years later was glorious revolution with a bill of rights, marking individual freedoms
1764: ten years later, beginning of American Revolution and being free of monarchs
1849: ten years-ish later, start of US civil war; was the time of an attempt by the British to end slavery around the world
1936: ten years later, colonial empires were being dismantled, UN established to attempt global cooperation, US in the ascendancy with a seed of ties being established more by economics than military force, great economic upswing lifting people out of poverty (60% in poverty then, 10% now) while the global population blossoms
2035: Majority of the global population in middle class or better, triumph of individuals over technocrats, bureaucrats, and corporatists :)

I’m a long time lurker (under old defunct alts) and occasional poster but I’ve opened HN almost every day since I discovered the site in 2008.
This community has an outsized impact on my career and life and I’m eternally grateful for it. Thank you!
Happy new year and eine Guten Rutsch ins neue Jahr.
(And I did had an awesome drug and alcohol free party with self made music and wild dancing)
Otherwise check out ecstatic dance for a similar vibe. (If you were refering to the wild drugfree party)
Wow. I can remember the days that I just came for the science and not the technical stuff because I found it too hard. Then quickly later using the technical articles to accelerate my computer science studies and now it just feels like I can dive into anything.
Love this place <3
Happy New Year! Buon anno a tutti!
Similar story with weed, except I can't dose it, it's either nothing or completely baked, so I'm switching from "baked from Friday evening to Monday morning" to "one evening per two weeks". The worst part was the brain fog, I could feel myself becoming more and more stupid.
Probably I'd enjoy a lot some stimulants, but virtually all of them are highly addictive, so yeah. I do LSD every now and then, which is super fun because it does have a stimulating effect, but it's something you can only do every few months, so yeah.
I feel much better today than a year ago, where I was hangover most of the day
As the clock ticks into a brand-new year, let’s toast to the innovators, the builders, the thinkers, and the dreamers who make this community so vibrant. Here's to:
- Writing elegant code and tackling tough bugs. - Exploring new frontiers in tech and beyond. - Learning, sharing, and leveling up together.
May this year bring you breakthroughs, discoveries, and joy in every pull request and project.
Keep building. Keep dreaming.
Happy New Year, HN!
How?
0! = 1 so how does 3^2*5 become 2025?
I wish everyone here had a good one and has a good one.
Merry 2025!
And thank you to everyone else for being generous and smart contributors.
2025 is going to be an interesting year - and I wish for y'all the best.-
Happy new year :)
I also monitor the changes of the hexadecimal unix timestamps. The next time the first of 8 hex digits changes is in 2029.
from datetime import datetime
'{:02X}'.format(int(datetime.now().timestamp()))
datetime.fromtimestamp(0x70000000)
And this spits out the year in Python: 3**2**2*5**2(20+25)²
(∑n)² and ∑n³ for n 1..9
The others in Python:
sum(range(1, 10))**2
sum(n**3 for n in range(1, 10))I know so few of you but feel like you’re my best friends. Love to all.
Besides family breakfast, brushing teeth/shower, opening HN makes a good morning better, and an okay start into what will hopefully be a great year.
Here's wishing everyone out there: 1. happiness, 2. purpose, 3. love, 4. health, 5. peace, 6. good flow, 7. clean code ;-).
Happy Hacking!
In 2025, I hope we can continue to push the boundaries of innovation, tackle complex challenges, and learn from one another. Whether it's through elegant code, groundbreaking research, or thought-provoking discussions, I believe this community has the power to make a lasting impact on the world.
As we reflect on the past and look towards the future, let's remember the values that have made Hacker News so special - a relentless pursuit of truth, a commitment to intellectual honesty, and a genuine desire to uplift and support one another. These qualities have been the bedrock of this community, and I'm confident they will continue to guide us in the years to come.
Here's to a new year filled with breakthroughs, discoveries, and the joy of creating. May 2025 bring us closer together, sharpen our minds, and inspire us to reach new heights. Happy New Year, Hacker News!
I'm thankful that this site exists to allow me to catch up on the news, events, and perspectives that I'm most interested in. And I'm even more thankful that it uses a simple, functional layout.
Keep rockin' into 2025, HN!
You mean Happy ++Year of course ;)
అందరికీ నూతన సంవత్సర శుభాకాంక్షలు!
అందరికీ ఆంగ్ల నూతన సంవత్సర శుభాకాంక్షలు!
I'll consider the previous one as advanced wishes for 30'mar 25 ;)
I frequently find myself saying: 'Yeah that was on HN a few weeks ago'! It's so up-to-the-minute and really just wholeheartedly good! Dang is a goddamned legend in my opinion I can hardly believe it works so incredibly well and it's surely mostly from dang's good work! Thankyou dang, so much!!
I think calendars (especially the gregorian) are fairly approximate things so try not to assign too much meaning to the number ticking-over these days.. sun/moon/earth/nature didn't care that our numbers ticked-over very much did they? But still, in order to be able to talk to others we have to try to store our memories using dates as keys (I'm actually really crap at that, but still!), so HOORAY for the next approximate-date-memory-key-era!!
Much love to all teh hackers! You are all awesome! Even the black-hats!! Curiosity FTW!!!!
Hex 37 (int 55) years Since Epoch (Jan 1 1970)
Lets hope its a pattern that spreads more broadly in 2025. We are already getting past the first quarter into the 21st century after all.
Happy New Year HN!
Thanks for teaching me so much <3
Learn OCaml in 2025
I hope 2025 is a year of real changes in terms of progress, peace and less polarized world.
For the record, I'll try my best for personal and professional growth.
Happy new year!
Hope this is a great year for everyone!

Remember - the new year is not yet written. Amazing and unexpected things are sure to come.
You know the internet has porn and discount bulk goods on it right
Spending the last day of the year without electricity was a huge wakeup call that big changes are needed. It has left me wondering why fusion energy has taken so long to develop, so that's a topic I'm really interested in exploring.
Reading some Peter Turchin, not looking good.
Curious to hear if anyone has any specific goals/resolutions/things they’re especially looking forward to in 2025.

Only 13 more years now 'til 2038! Maybe we can still fix that problem! But feel free to take today off, hackers.
With a new year / с (наступающим) новым годом / з новим роком
Stay amazing HN, and have a brilliant 2025.
setYear(year => year + 1)
For the "get off my lawn" crew: $('#year').text(Number($('#year').text()) + 1)Get off my lawn means no libraries, just web api.
I love you, my favorite site ever.
Happy New Year to all of us
This was around 18:10 PST so the greeting may have introduced a race condition.
Happy New Year anyway, logic be darned!
But as to your real question: well, tune in, man. :)
