ccostes··on Ask HN: Ex-FAANG developers, where are you now and why?
Interested in hearing more about what you're up to. What's the best way to get in touch?
ccostes··on Bloomberg News Pays Reporters More If Their Stories Move Markets
I think this is where editors would come in who (presumably) don't have the same incentives.
ccostes··on Voice Phishing Scams Are Getting More Clever
Super cool, thanks for sharing this!
ccostes··on Ask HN: What are some of the best documentaries you've seen?
Wild Wild Country completely blew my mind. It didn't happen that long ago, seems like it would have been major national news on a number of occasions, and yet I had never heard anything about it before watching the doc.
ccostes··on A spreadsheet of the businesses I've started over the past 15 years
Really interesting, thanks for sharing this.

Why is it called Cedar & Sail when (as far as I can tell) it has nothing to do with either of those things? :p

In any case, congrats on hitting it big with Baremetrics!

ccostes··on Teenager Finds Classical Alternative to Quantum Recommendation Algorithm
I chuckled when I read it and took it as tongue-in-cheek.
ccostes··on Introducing Multi-Leg Options Strategies
> Source: Was an electronic options trader

So did you make your millions and retire to an island, or did the options trading not work out?

ccostes··on My struggle to learn React
I can definitely sympathize with the issues that come from not being familiar with ES6. I'm working through a React Native tutorial currently and, while I've managed to understand some of it via context, there's some very odd looking syntax that I still don't understand.

Can't really comment on the rest of the React ecosystem until I get through the tutorial and start trying to do things on my own.

ccostes··on How to Decide What to Build
I like the advice to actively record your ideas (every little one). Thinking about things in abstract, it can seem like all the good problems are solved, but listed out on paper it is a lot easier to analyze and notice patterns.
ccostes··on PowerHammer: Exfiltrating Data from Air-Gapped Computers Through Power Lines
I think you're stretching the definition (at least at a conceptual level) of "Air-Gapped" when your means of communication are connections that go through the air-gap.

I guess there are probably real systems referred to as "air-gapped" that don't have power isolation they could be addressing, but it still feels a little disingenuous.

ccostes··on Tesla Was Kicked Off Fatal Crash Probe by NTSB
The most advanced autopilot systems today can navigate and even land the aircraft, but the majority of systems (especially on general aviation aircraft, but even many commercial) are closer to what you describe, and can kill you if you're not paying attention.
ccostes··on Dapps
I think the analogy breaks down somewhat due to the relative scale of their misses vs. hits. A batter can only get so many runs with one hit, but a good investment can make all of the misses look like rounding errors.
ccostes··on Mark Zuckerberg testifies before Congress
My impression was that he wasn't under oath for the hearing. Honestly, for the level of technical complexity they are discussing (often in very non-specific and general terms), I don't think they'd be able to have a conversation at all if every statement Zuck made had to be legally bulletproof.
ccostes··on YouTube Face is clickbait, attaining human form
They really are effective, though. The conscious part of me is actually turned off by videos with these kinds of title images, but they still draw my attention and produce an impulse to click.
ccostes··on Why SQLite Does Not Use Git
> But it's more interesting to compare the philosophies between the two tools.

So what are their philosophies? Fossil is for small things and git is for scalability?

ccostes··on Why SQLite Does Not Use Git
Interesting, I hadn't heard of Fossil before.

It is useful to have a 'lingua franca' of open-source version control, but I'm not sure git is necessarily the best choice for that (not that network-effects usually result in the 'best' being chosen)

ccostes··on Productivity
I think the idea was to actively consider whether you are working on the right things, rather than suggesting inaction.
ccostes··on Stratechery 4.0
I like the effort to categorize previous writings. I primarily listen to the podcast and think Ben has some really great insights and theories that he's clearly put a lot of thought into (the perennial favorite: aggregation theory), but are sufficiently complicated that they can't be re-explained every time they are mentioned. Making it easier to look back into the archives seems like a good way to address this problem.

New logo looks really nice, too!

ccostes··on A startup is pitching a mind-uploading service that is “100 percent fatal”
I think the point about unconscious states was not that you "become no one", but rather that it is an interruption to the continuity of consciousness.

As a thought experiment, imagine you were magically replicated during sleep such that, at the time of replication, both "you"s were completely physically identical. Both would wake up thinking that they are the same person that went to sleep, but now there are two of them. Are either/both/none of them "you"?

My answer would be that they both are, and don't think there's anything special about our physical selves, nor any reason that we're limited to being singletons (to give a code analogy). The combination of our physical self and our cumulative experience and memories are what defines "us". Thinking of identity in possessive terms and the desire to think of ourselves as unique is a quirk of psychology, I think.

ccostes··on Ten years of professional blogging – what I’ve learned
I found that odd, too. Guess it's sort of like a tl;dr, but it felt repetitive.
ccostes··on The Last of the Iron Lungs
It's really true that, as someone in my 20's, polio really did seem like a thing of the past before reading this. While I knew what an iron lung was (always disliking the name, though), I had no idea there were still people using them.

The most striking thing is how early in life these people were affected, while I feel like I've only just begun to experience life. Really makes me appreciate all the work that went into the vaccines and public health to make a disease that was so terrifying only a generation ago, virtually non-existent today. (And really hate that the anti-vaxers, who benefited from it, are working to undo such a great achievement)

ccostes··on OnePlus OxygenOS built-in analytics
Merger may be unlikely, but reorganization seems like a fairly low bar.
ccostes··on What Rust Can Do That Other Languages Can't
The counter-argument to this being that the safety checks imposed by Rust prevent errors in the first place, saving debugging time and getting features out more quickly.
ccostes··on Atlassian acquires Trello for $425M
They spin out each of their products (Stack Overflow, Trello) as separate corporations so Fog Creek didn't own Trello.

Edit: I guess the spinning-out doesn't say anything about ownership (though the article does say Trello did a round of funding after the spin-out)

ccostes··on Ask HN: If you were to switch career, what would you do?
Side note: having hobbies unrelated to your day job is perfectly normal and healthier, imo, than spending all of your time on one thing.

Life is all about balance.

ccostes··on Renewing Medium’s focus
I applaud Medium for renewing their focus on achieving what seems to be the holy grail for virtually all content producers, but especially writers: getting people to pay directly for content. Netflix and the like seem to have it figured out for video, but somehow it is a much harder nut to crack for text.

I agree that it would be better, both for producers and consumers, to find a different model, so I hope they can figure it out!

ccostes··on Rust is mostly safety
Part of the issue stopping me from jumping in is that it feels like the language is still changing in ways large enough to make it difficult to learn. That may not be true anymore, but it seems like it would take a lot of work to keep up with the current 'best practices'.
ccostes··on UW engineers achieve Wi-Fi at 10,000 times lower power
Their video from 2013 shows some pretty cool applications of an earlier version of this tech that looks essentially like passive NFC using ambient RF rather than using 802.11.

Very cool stuff!

ccostes··on The liquidity what if? Our alternative to employee options/equity grants
I like the idea as a way to distribute gains to employees. Wondering why the units are limited to integer years rather than allowing constant accrual up to the 5 units.

Additionally, it seems unfair that employee units go immediately to 0 upon leaving, rather than some sort of decay. They're saying that employees contributed to the success and deserve a bonus, why would that contribution be worth nothing the minute they leave? Something like an exponential decay on the units seems much more equitable.

ccostes··on Amazon Go
People shopping with children would also be a big issue, it seems. Somehow it seems they will need to deal with the multiple-shopper case (no idea how to solve the "Have someone else get the item off the shelf for you" case).
