cblum··on Tell HN: Happy Easter
Happy Easter! Hope you had a day filled with joy and assurance of His and our resurrection!
cblum··on Never pay for online dating (2010)
Paying for online dating was the reason I met my wife.

I had been using several dating apps and had paid subscriptions to all of them. I was getting burned out by the experience and decided to let my subscriptions expire and take a break from dating, so I wasn’t actively checking the apps anymore.

A paid feature of one of the apps I was paying for (Coffee Meets Bagel, for the curious) was that it notified me whenever someone liked my profile. One day I got one of those notifications, checked her profile and arranged a first date.

And now here we are, happily married :)

cblum··on Ask HN: Non-violent video games with great stories?
Overcooked 2 has been a huge relationship builder for my wife and me.

If you put your heart in it, you learn to communicate effectively under pressure (especially when trying to conquer those 4th stars), tolerate/move-on from each other's mistakes, and control your temper around each other.

We've been recommending the game to every couple we know.

Can you provide a link to that?
cblum··on I Don’t Want to Be Like a Family with My Co-Workers
> I have people I care for and would be there for if they needed

That’s my personal definition of friend, as long as it’s mutual :) The level of intimacy may vary, but if the “being there when needed” component is there then I regard a person as a friend.

I went through a couple of really hard life events during the pandemic, which was already hard enough. It was bitter to find out that some friends weren’t really friends. On the other hand, some people I only regarded as acquaintances turned out to be friends.

Gonna plug my own sectorforth here: https://github.com/cesarblum/sectorforth

The linked post is really impressive. The author went way beyond what I did. I'm especially impressed by the I/O stuff.

cblum··on How Tech Loses Out
> Tell me more about how people hate writing documentation

The thing is, I don't this happens in isolation. At least not for me. I hate writing documentation because time is not allotted for it. So I have to rush it, and in the process I feel like I'm doing a poor job, which is demoralizing. I'm gonna dread it next time I have to do it.

cblum··on I am seriously considering going back to desktop computers
How does one find a job like yours?
cblum··on Show HN: Greg – a simple “cal” clone written in C
I share the feeling. You're not alone :)
cblum··on I am an Uighur who faced China’s concentration camps
I tried raising awareness about China's bullshit at work once, and was met with awkward silence and was later told in private that I came off as ignorant/immature.

All because I said China should be regarded by the West as an enemy/hostile state. Hell, it's the one thing I can side with the current administration on.

To me China is not much different than pre-WWII Germany: over-the-top authoritarian, has ambitions to influence the direction of things at the world stage, and is currently scapegoating an ethnic minority and putting them in concentration camps.

That wasn't the first time I tried bringing those things up in a group setting. In other occasions I was only met with awkward silence too. Feels like there's some subtle but insane denial going on.

cblum··on Aliens on 1k nearby stars could see us, new study suggests
> with the new Voyager discoveries lately

What new discoveries, specifically?

cblum··on iPhone 12 Pro so costly in India, you can fly to Dubai to buy it and save money
That’s surprising.

I grew up in Brazil near the border with Uruguay, and we’d always cross the border to buy our electronics at the duty free stores. It was massively cheaper than buying them in Brazil.

Are duty free stores only present in border areas?

cblum··on My platonic ideal for how engineering hiring should work
I haven't personally, but my ex-wife is a developer at a FAANG and she told me multiple stories of people she phone screened who couldn't actually write a simple for loop.
cblum··on What if a pill can change your politics or religious beliefs?
Ecclesiastes was absolutely life-changing for me.
cblum··on Infection fatality rate of Covid-19 inferred from seroprevalence data [pdf]
You presume to know me.

I actually pick up food from local restaurants around me.

I (and many other people) continued to pay my gym membership when they had to close due to the lockdown, to support them during that time.

And so on.

I don't even have the option not to wfh (and even if I had, why would I go to the office and risk unnecessary exposure to the virus?), since my office closed for our safety even before government lockdowns became a thing.

> Or make any large scale sacrifice

Sacrifice is exactly what people aren't doing and why we're living through this disaster.

The sacrifice we should be looking at is not the risk of catching COVID-19. It's that of following a set of rules that drastically minimize the spread of the disease. Simple rules, by the way.

If everyone had the kind of thinking some (most?) Asian societies have (collective first, individual second), we'd be looking at a much different world right now. I'm thinking mainly of Taiwan.

But no, we have to deal with people throwing tantrums because they can't wear a piece of cloth over their faces.

cblum··on Infection fatality rate of Covid-19 inferred from seroprevalence data [pdf]
I confront people who think they'll be ok because "the fatality rate for my age is only, like, 0.1%" with this question:

You would play the lottery with those odds, wouldn't you? But you don't want to play that lottery.

People don't realize how high odds of 1 in a 1000 are until you flip it around like that.

cblum··on What if a pill can change your politics or religious beliefs?
> reading Chomsky as a teenager, Plato in college and Kant after that were much more significant events in terms of my political views

I can relate a lot to this. I'd say my formative reads were:

- 1984 and Brave New World. The former should be mandatory reading for everyone, everywhere.

- The Bible. Going from "I was raised Christian" to "I'm gonna read this and ask myself if I really believe this stuff" (I do, but in general I deviate massively from mainstream evangelical Christianity).

- Dune. Yep, profoundly transformative. I'm bummed that some people I've recommend it to don't seem to have had the same experience as I had reading it.

Wow, that’s surprising. Seems so backwards.

> or switch class brackets.

Can you elaborate on that? What does that mean?

cblum··on When do we become unable to learn a language like a native speaker? (2018)
I've authorized a friend to correct me like that whenever he sees fit (I'm ESL and I really want to be able to speak English like a native speaker), and I've learned a ton since then.

Oh yeah. It's the _one_ thing I can agree with them on.

cblum··on Why Forth Isn't Slow (1985)
Learning how Forth is implemented and then implementing my own totally blew my mind. I've fallen hard in love with Forth.

My greatest motivation to learn Forth inside and out is its value in rebuilding civilization if we ever find ourselves in a place where a significant amount of technology has been lost. I don't think there's a more powerful and yet incredibly simple way to bootstrap a general purpose programming environment than writing a Forth. It's a relatively small amount of knowledge that needs to be preserved, compared to all the complexity that would be needed to have compilers, garbage collectors, and all that jazz again.

I mean, that's just my personal take on it.

cblum··on Why Forth Isn't Slow (1985)
I fell into that rabbit hole thanks to the quarantine. I've been find it therapeutic: the simplicity of it is unbeatable. It gives me the same sense of speaking directly to the machine that assembly does, but at a higher level. I've also grown to love RPN.

I posted my project here just the other day: https://news.ycombinator.com/item?id=24604457 I had an absolute blast working on it, and I'm looking forward to my next Forth-related project (still deciding on what it's going to be).

cblum··on It Is Never a Compiler Bug Until It Is
I caught a JIT bug in .NET back when I worked at Microsoft. Unfortunately I don't remember the specifics, but it was doing something wrong when trying to optimize a bit of code using AVX instructions.

I was immediately sure it was a compiler bug when I realized I could make the code work correctly if I changed the order of variable declarations. It would happen on something like:

int a; int b; float c;

(again, that's only illustrative - too long ago for me to remember the specifics)

But not with:

int a; float c; int b;

Folks in my team didn't want to believe it at first :)

Edit: found it here - https://github.com/dotnet/runtime/issues/17395

Not quite as I described but close.

We've talked over email. Hope my pointers were enough to get you unblocked :)
