fernandopj··on NASA acknowledges it cannot quantify risk of Starliner propulsion issues
IIRC the Crew 9 mission was postponed for exactly this reason. At some point, Starliner needs to be kicked out because they need the docking space. They can't keep postponing ISS missions as they please.
fernandopj··on NASA acknowledges it cannot quantify risk of Starliner propulsion issues
I thought the 24 September date was for them to return using that Dragon capsule within days, was it not? They would have to send two less people on Crew 9 mission, then wait the entire mission duration to return? That's so odd.

I'd imagine they would just change the mission to send an empty Dragon in March to get them, but use the launched September Dragon to return those Starliner astronauts right away.

fernandopj··on Ask HN: How to build site with payment, subscriptions, user login, registration
There's a niche service nowadays called "SaaS-as-a-Service" where an entire SaaS ready to use and customize is priced to you. I didn't use one myself but [1] is a good example.

fernandopj··on CrowdStrike Update: Windows Bluescreen and Boot Loops
One reason being that Microsoft lobby hard against low-end PC & notebooks that are not aligned with its interests. [1]

Microsoft has a large, entrenched distribution network and market all over the world. It makes an uphill battle to create low-end programs for schools, universities, governments, SMBs.

Hence the phrase "no one was ever fired from buying Microsoft". It's too hard a battle to go against the flow.

fernandopj··on The demise of the mildly dynamic website (2022)
You have to consider that AWS Lambda does have "cold start" - if your code wasn't run for about 10 minutes it isn't "hot" anymore and will have a penalty time cost to its first next request. This is not billable but it is a latency, explained here [1]

fernandopj··on Noam Chomsky has passed away
I'm trying to confirm it as well and wasn't able. Never heard of any of those above sources.
fernandopj··on Super Heavy has splashed down in The Gulf of Mexico
I've been trying to find an "outside" view of the landing, as it is usual with SpaceX' dropships. So far no luck, they just haven't showed it yet or because it was middle of the ocean they probably don't have one?
fernandopj··on Footage of Chang'e-6's land on far side of the moon
Definitely. You can see the lander "breaking" to adjust fall trajectory twice, the actual burst wouldn't be that fast.
fernandopj··on Show HN: I built a game to help you learn neural network architectures
I've only been able to solve the RNN problem because out of frustration I tried every combination possible. It was 3 edges.

When I got to the second one without any stated goal or meaning, and it said "19 edges", I gave up.

fernandopj··on Today Microsoft Banned My Country Iran from Minecraft
Minecraft is an online game, so in today's world, he didn't purchase the game, just a license to play it online. No server access, no game.
fernandopj··on Avoid blundering: 80% of a winning strategy
Anecdotally of course, but that was not my case at all (and I imagine for a lot of people). Counter-intuitively I guess, but I could see a lot more flops just because I would have a) a lot of correct readings by turn and b) easily exploit obviously bad EV plays by others, regardless if I won at showdown.

Folding a lot makes you a boring player, but getting involved a lot and "somehow" getting a lot of chips eventually makes you _dangerous_ at these friendly gathering and that's what gets you unwelcome (at play - I'm still friend with these people I'm talking about).

fernandopj··on Avoid blundering: 80% of a winning strategy
Exactly. This is the reason at one point I stopped being invited to casual poker games with friends of friends. I was amateur level compared to professionals, but just because I don't make blunders, any game session 4 hours long were enough for me to systematically get most if not all of everyone else's money and ruin their fun.
fernandopj··on Vice website is shutting down
Do elaborate!
fernandopj··on Pitch CEO resigns, reduces team by 2/3, and opts out from hyper-growth/VC
From Techcrunch: https://techcrunch.com/2024/01/08/pitch-christian-reber-vent...

> "Pitch had raised north of $130 million in funding..."

I'm sure I'm not the only one baffled at how much they were able to raise for such a product.

I looked into Canva to compare valuations in that market. Canva is at US$ 25b [1], which is astounding to me (but down from $40b in 2021 [2]). So I guess they're looking to turn Pitch into something at 2b I guess.

IMHO the CEO acted correctly if he felt the company & product couldn't hypergrow. They didn't burn cash building a massive headcount. He worked at the product & market long enough to reasonably argue how much the company could grow. He returned money, downsized the company presumably to a point where it could self-sustain. He did good by their investors, the headcount wasn't sustainable I guess. And resign.

It's regrettable of course, so many lost their jobs but I don't see how his conduct is reprehensible.

fernandopj··on US homelessness up 12% from 2022, hits highest level since 2007
Presented to you by the same makers of "if artists didn't make money, art would stop being produced"

I don't see clothes as investments but I still buy them, same as food. And industries are there to provide and profit over it.

If somehow magically houses stop being "investments" to hoard and rent away, people would still build houses, you know, to live in them.

fernandopj··on Show HN: AI Generated SVG's
When I click to see an imagem from the gallery, it looks like it loaded but then a blank screen appears instead, after what looks like a refresh. Tried on Chrome and Firefox.
fernandopj··on Jeremy Vaught spent 16 years to build @music on Twitter, then X took it away
> At this point it's all but inconceivable that those would be removed from the app servers, iOS or Android.

Not at all: one could see a future where any of those companies become Uber rivals - they're both researching autonomous vehicles. When that comes, one incident at Uber and its reason enough to expel them.

fernandopj··on The Wealth Gap in Science: How Your Parents's Income Affects Your Career
Anectodally, this reminds me of a discussion I heard coming from a former boss, discussing a team which had two junior graphic designers and one of them was being let go.

He concluded that it was a shame that the one who was somewhat more resourceful, or arguebly slightly more competent tool-wise, was just not at the same level as the other one because that other one you could see that was exposed to arts from a young age, so it could naturally argue about colors and aesthetic in a way the other one just couldn't grasp. He was just He just couldn't see how he could eventually overcome this gap with his peers, and he would most likely have that difficulty throughout his career.

fernandopj··on Dragonfly Is Production Ready (and we raised $21M)
Putting aside what seems to be an amazing new product, but the blog post showing the results are also downplaying what (to me at least) seems to be a 25% or more increase in latency.
fernandopj··on Launch HN: Defer (YC W23) – Zero-infrastructure background jobs for Node.js
This is an awesome value proposition. Congratulations on launching!

I have a project that I've been dreading on how I would tackle its background processing. It is a long-running process that should start and scale based on a user starting his work. I'm AWS certified and still wasn't thrilled about setting this up. Defer would solve this for me.

I can see myself suggesting this solution to clients who want to run complex jobs without the hassle from cloud infra.

Resume/CV: https://angel.co/u/fernando-piancastelli Email: fernando@cellide.com

I've landed a job using this posting last year, unfortunately it was a startup trying a last-minute pivot, it didn't launch to an immediate success, as they hoped, so they decided to close shop. It lasted only 3 months so I'm in the market again.

If you'd like to see some of my current work, I'm launching an OS project to make AWS diagrams purely from Terraform: https://github.com/fmalk/terraform-plantuml . No changes to files or configs are needed. Still in alpha stages but it currently maps buckets, users, VPCs, subnets and EC2 instances.

I'm a software engineer focused on leadership and process automation. For the past 12 years I have been leading teams, designing solutions & architectures. I mostly work on backend with APIs, message systems built on NodeJS & AWS but I keep in touch with React web & mobile. Love teaching juniors and coding best practices. I'm out of practice with C# but used to love .NET.

My immediate family is planning a move to England so I'm open to it as well.

I've talked to them before, they seem great, check them out.

fernandopj··on Paul Buchheit says Google may be only a year or two away from total disruption
Google don't mess around existential threats to their search business model.

We're talking about the company who, when they saw the iPhone, recognized the mobile apps space as a threat to search (why search if they can open an app from a walled garden) and immediately went to work on Android, even if they were never in the phone business. They reacted faster and better than everyone else and the entire phone space as it was went bankrupt (Nokia, Blackberry, et al).

I have no doubt in my mind Google have ChatGPT as a top priority threat, and they'll come up with something to counter it. And Google already invest heavily on AI, they're not completely offguard.

If somehow someone invented a car, today, that could threaten ad search from Google, they'd be competing with Ford, GM etc in two years.

fernandopj··on Ask HN: With recent layoffs, how would you advise new grads entering the market?
> Network aggressively and be likeable. You never know when that linkedin connection from a shit job 3 years ago will throw you a bone. I know everybody on HN really likes their leetcode but if you have an inside reference, the interview is reduced to just a vibe check.

++1 this. Couldn't have said better myself. I went more than 10 years not having to apply anywhere, switching jobs just by referral - interviews felt like friendly meetings. Only broke that streak when interviewing for a job in another country.

fernandopj··on Using paleogenomics to elucidate 10k years of immune system evolution
You're making the same mistake as the OP: looking in isolation at the current, final step of a process that took millions of years. Also, you're gonna find a lot of different immune systems in nature, just as you can find many different eyes/vision in animals. There's a lot of middle ground in species that saw no advantage in evolving that particular system against their environment.

You're also confusing the randomness of the steps with the somewhat previsible trend of an entire ecosystem which is evolving. If world is getting warmer and air more dense, you wouldn't be able to guess which mutation occurs but you can predict in time animals would be more adapt to that new ecosystem.

Darwin famously looked at a unusual orchid with a long "tube" leading to nectar, and spoke that "there must be a bird with a long beak here somewhere". He didn't find it at first, but it was discovered later [1]. So you can apply some predictions at how evolution took place if you take a look at the environment. Just as one would guess there must be an immune system in animals if you discover diseases, virus, bacteria etc - or else how would large animals exist?

fernandopj··on Human Chess is a chess variant where playing the top engine move is forbidden
This is already how some engines tournaments work. They don't start from move zero, they start from some uncommon position after a few moves, but one still considered even or at least not unbalanced.

fernandopj··on Show HN: We built a tool that automatically generates API tests
Fantastic project. I worked on something similar that had the same approach, but the main goal was to test availability in different environments (dev, stage, production) against the same tests. We also had the feature of using the result of one test as input to another, so a complete user case from an API could be tested (auth, POST data, GET results)
