meken··on Command-line Tools can be 235x Faster than your Hadoop Cluster (2014)
I’m curious about the memory usage of the cat | grep part of the pipeline. I think the author is processing many small files?

In which case it makes the analysis a bit less practical, since the main use case I have for fancy data processing tools is when I can’t load a whole big file into memory.

meken··on The URL shortener that makes your links look as suspicious as possible
I can’t speak for the author, but this strikes me as the kind of thing you might not want to check prior work on. It just seems like a fun little project and sometimes seeing that other people have done it can be a bit demotivating.
meken··on Ask HN: What did you find out or explore today?
I found out that Eastern Europe includes the Baltic States (northern) and the Balkans (southern).

I learned this because I play a daily game called FoodGuessr, where you have to guess which country a food dish is from. I tend to struggle in Eastern Europe.

meken··on The URL shortener that makes your links look as suspicious as possible
I’ve been browsing this site for a decade plus and this idea was new to me. Maybe the author is in the same boat.

Edit: I see referencnes to shadyurl in the comments and I have heard of that, but probably wouldn’t have thought of it.

meken··on Show HN: Seapie – a Python debugger where breakpoints drop into a REPL
I have a version of this, but it’s “open a Jupyter Notebook here” [1]. Though it’s not as polished as yours.

meken··on The struggle of resizing windows on macOS Tahoe
Wait I literally thought the ChatGPT desktop app has been broken for months (both dragging and resizing the window has been super inconsistent).

Could it be that I just need to drag the window outside of the pane..?

meken··on Rats caught on camera hunting flying bats (2025)
(2025)
meken··on Creators of Tailwind laid off 75% of their engineering team
Sounds like 3:

meken··on Creators of Tailwind laid off 75% of their engineering team
Thanks for that - the GitHub app “helpfully” collapsed this comment (along with most of the others in the thread), so I was confused how the headline related to this issue.
meken··on Neural Networks: Zero to Hero
Has anyone gone through cs231n and this as well?

I went through the former and it was one of the best classes I’ve ever taken. But I’ve been procrastinating on going through this because it seems like there’s a lot of overlap and the benefit seems marginal (I guess transformers are covered here?).

meken··on Ask HN: What did you read in 2025?
I started in August, but the two books I read were Treasure Island by Robert Louis Stevenson, and East of Eden by Steinbeck.

I tried reading Catch-22, but 50 pages in it just seemed like a bunch of military guys trolling each other by being as autistically literal as possible with absurdist Airplane-style humor. I noped out at the prospect of reading 500 more pages of it. I don’t get why people here recommend it so much.

I recently started reading Moby Dick.

meken··on I program on the subway
> Currently I am working on affixing a split keyboard to my pants, so that I can program while standing up.

This reminded me of the "walking desk" Stephen Wolfram uses to program:

I tried to use a similar one during Covid and couldn't get into it at all.

meken··on Show HN: I made a down detector for down detector
We could create a linked list of these and just refer to the N’th one as N-down detector.
meken··on How do the pros get someone to leave a cult?
Fascinating. I would totally watch a TV series on this.
meken··on The Baumol Effect and Jevons paradox are related
> If you can make $30 an hour as a digital freelance marketer (a job that did not exist a generation ago), then you won’t accept less than that from working in food service. And if you can make $150 an hour installing HVAC for data centers, you’re not going to accept less from doing home AC service.

Plenty of people work jobs for less money because they enjoy the work more. I’m not sure if it’s worth reading what follows if most of the argument is predicated on this claim.

meken··on The fate of "small" open source
It would be a cool feature of AI to include only the subset of the library you use and nothing else.
meken··on The fate of "small" open source
> ….but I do think it’s a future where we prize instant answers over teaching and understanding

It depends. For stuff I don’t care about I’m happy to treat it as a black box. Conversely, AI now allows me to do deep dive on essentially anything I’m interested in, which has been a massive boon to my learning ability.

meken··on Things that aren't doing the thing
I see lots of comments focusing on cases where there is necessary research still to do.

Which I think misses the point - which is there are times when you’ve already done enough research, but you’re afraid to act so you procrastinate. i.e. not doing the thing.

meken··on Awk Technical Notes (2023)
This sounds interesting. Could you give an example where you rewrote a pipeline in awk?
meken··on Project Euler
One of my best memories was in undergrad there was one semester in 2013 where half a dozen of my CS classmates and I competed to try and solve the most Project Euler problems. We had a leaderboard and everything.

I saw first hand how much faster my friend’s Java solutions were than my Python solutions.

Good times.

meken··on Ask HN: What Are You Working On? (Nov 2025)
Not an original idea, but I’m working on writing a minimal OS to run Doom.
meken··on The Hacker’s Manifesto (1986)
The author doesn’t explain the jump from finding community online to committing crimes/hacking.

Or did I miss it..?

meken··on Backpropagation is a leaky abstraction (2016)
He gives an update in the Dwarkesh interview:

https://youtu.be/lXUZvyajciY?si=vbqKDOOY7l-491Ka&t=7028

Not too many details on timeline - just that he's working on it.

meken··on Magit Is Amazing
magit is the only thing I use Emacs for (well, sometimes I also use json-mode and json-pretty-print).

I prefer Spacemacs though.

meken··on Ask HN: What are you working on? (October 2025)
Not an original idea, but I’m writing a minimal x86 OS that will run doom.
meken··on Python's splitlines does more than just newlines
TIL: Python has a splitlines function
meken··on Demand for human radiologists is at an all-time high
From the article:

> Some products can reorder radiologist worklists to prioritize critical cases, suggest next steps for care teams, or generate structured draft reports that fit into hospital record systems.

meken··on Learning Persian with Anki, ChatGPT and YouTube
I, too, had the same frustration as you - until I figured out you can hold down the circular icon while you’re speaking then let it go when you’re done and it won’t interrupt you.

Edit: it looks like they updated the Voice Mode UI since I last used it - hopefully they retained this capability.

meken··on MapSCII – World map in terminal
I play a daily game called FoodGuessr, where you guess the country that some kind of food came from

Would be fun to use this with that - thanks!

meken··on Becoming the person who does the thing
There are paradoxes and chicken-and-the-egg problems throughout the article:

> For me, something shifted in my late twenties. Growing up I guess you could call it. I don’t remember the exact straw that broke the camel’s back, but a desire for change grew.

> If you identity as a failure, incapable of achievement, unfit, unlovable, destined to play a bit-part role in your own story, then by heck no matter how much willpower you put in to push that boulder up the hill, it will return to its place.

> You have to actually want it.

How do you actually want to change? That part remains largely a mystery, and appears to be the all-important ingredient everything pretty much flows from.

At the end of the day, nobody knows why they want certain things - they just do. There is a lot of magic to that part. Where does "motivation" come from?

I go back and forth on this, but I pretty much settle on that motivation is the all-important ingredient which no one actually knows much about and all the rest is just backward-rationalizing to make ourselves feel good and feel that we have more agency than we really do.
