whoisjuan··on Blue Origin: Toxic, dysfunctional ‘bro culture’, low morale and delays
The main problem with Blue Origin is that it isn't SpaceX. And I think Bezos clearly knows that he has a very small window of chance to make it work. So I bet the top-down pressure is insane. Perfect condtions for a toxic culture.

So if you get a job at Blue Origin with the expectations that is going to feel like working for a cozy, cultural-heavy, trendy startup, you probably should re-caliber the way you set your expectations.

whoisjuan··on This influenza lineage may have become extinct
This is not surprising at all. I haven't had anything that feels like a cold or a flu, since COVID started. I think this can be mostly attributed to the sudden increase of mask usage and hand-washing.

I believe influenza was very vulnerable to this change of behavior given its seasonal nature, shorter incubation period and generally weaker virality.

whoisjuan··on Pausing “Instagram Kids” and building parental supervision tools
I don't disagree with you, but this is not a situation where you are going to find a solution in the problem cause.

Many parents will keep raising theirs kids with undiscriminate access to smartphones. Just because you have it under control in your household, doesn't mean everyone does.

You're basically saying: "Not my kids, not my problem".... and that's the position many will take.

I'm not convinced IG for Kids is the right solution, but it is at least an intentional move towards fixing the foundation of the problem. It will take more than that, though. It's probably a problem that needs to be fixed by forcing big tech companies to cooperate, something that it's unlikely to happen in an era where those companies enjoy antagonizing each other.

whoisjuan··on We killed our end-to-end test suite
If your tolerance to deal with regressions and bugs in production is high and you have millions of users, then you can think of the user as the end to end tester. Maybe you ship some change and put it behind a feature flag and make it available to only 2% to 5% of the users.

If you get 1000 users to go through a particular flow and you have a way to collect failure signals from production accurately and in real time, then you can just dial down that flag to 0% if you see a lot of production errors.

I'm still not convinced that you can't drop e2e testing completely but maybe if your business allows it you can confidently rely of unit testing or testing contracts without having to run the app through all the user flows for every change.

whoisjuan··on Gitlab S-1
Every S-1 in existence says that. Why people always share this excerpt when an S-1 is listed here in HN?

Just look back at any S-1 post and there's always somebody who shares it. Why? Do they really think they are illuminating someone else with the most boiler-plate phrase in the existence of S-1 filings?

whoisjuan··on Intuit to Acquire Mailchimp for $12B
Most people think of Intuit as the company that helps them to deal with government bullshit and they are happy to pay for that.

The average consumer doesn't know that Intuit has a gross business model that is entirely based on the idea of deliberately keeping bureaucracy alive. They think the exact opposite.

They believe Intuit is giving them a solution to deal with the government's outdated and overly-complex tax filing system. And unsurpisingly the government has no issues with being the escape goat on this one, because the way you pay your taxes will never be as politically contentious as determining who gets to pay taxes and how much they pay.

whoisjuan··on WhatsApp moderators can read your messages if someone you talk to reports them
It sounds to me that there’s actually an algorithm between the report and the moderator to control the volume of manual moderation.

What you’re describing doesn’t work with E2E encryption. I really doubt it works that way.

whoisjuan··on How do I turn off the “Try the new Safari” notification?
> This notification should be escalated as a bug, as it violates Apple Human Interface Guidelines

Bold of them to assume that Apple will follow their own guidelines if they are detrimental to their product strategy.

Objectively speaking, these are guidelines, so they are not enforceable the same way App Store rules are. But there's also a lot to say about the differences between Apple as a platform and a Apple as a product.

I think Apple has never even remotely consider the idea of setting the sames rules for their third-party ecosystem and their own products. They have build billionaire business lines on the sole idea of products that integrate better with MacOS and iOS (Safari, Maps, Mail, etc) Anyone who uses an Apple product knows this. So I think is pointless to call them out on that. This has been Apple's playbook for the last 20 years and it will be for years to come unless regulation catches up to them. Time will tell.

whoisjuan··on Twitter starts to require login to view tweets
Doesn’t Twitter report that they have north of 500 million dormant users (people who use Twitter without an account)?

Given how much shit they get from Wall Street due to their super weak user growth, I’m suprised they didn’t do this long ago.

whoisjuan··on A third of Stitch Fix employees quit after new CEO ends flexible work hours
I don't disagree with what you're saying in a general sense. Creative people output will be better and higher quality than an algorithm...But I don't think that's the case for this business model.

Although I believe there is creative merit in composing an clothing outfit I don't believe that merit is even remotely close to things such as designing the actual clothes or creating the drawings and art that goes into the clothes or designing the stores in which these clothes are sold...

So I stand by my original statement. I do believe an algorithmic stylist for the avergage person can be vastly superior than a human stylist, because the inputs that the former takes are not that different than the inputs of the latter. Furthermore, the reasoning is essentially the same:

People want good fitted clothes, that are in fashion and that go in accordance to what they like. I don't think there's a lot of room for creativity here. I'm sorry that it sounds like a machine-learning nihilist take, but in practice I don't believe there's a good match between what people want from something like Stitch Fix and what a human stylist can do for them.

I dooubt that someone who relates to clothing in an artistic way would ever use something like Stitch Fix, so my assumption is that for the average Stitch Fix user, an algorithmic stylist could give them the same desired output at a better cost.

whoisjuan··on A third of Stitch Fix employees quit after new CEO ends flexible work hours
> An algorithm is just going to give me a mix of what's popular and what I've liked in the past.

That's exactly the same thing a human stylist would do + making sure the outfit pieces look good together (Which I assume the algorithm is also trained to do).

As much as I want to believe that a human in the end would do a better job, I think an algorithm is capable of becoming a more accurate and dynamic stylist than a human.

Unless you want to be a trend-setter or do some artistic expression through your clothing. In those cases a human stylist does make sense. But for the regular Joe, I think a well trained algorithm can perform better than a human.

whoisjuan··on Home Prices Are Now Higher Than the Peak of the 2000s Housing Bubble
Is this inflation adjusted? Because otherwise I don't see the point of that article. Of course home prices are going to be higher 20 years later.

Even if the numbers analyzed are inflation adjusted, the article doesn't explain in what proportion are those prices higher than in the 2000s. If a house value was 60% up before the bubble bursted and then house values crashed 60% you have a baseline which is the deflated prices after the burst.

whoisjuan··on SEC charges Netflix insider trading ring
They are idiots that can inside trade with impunity.
whoisjuan··on SEC charges Netflix insider trading ring
Entity trading is not going to obfuscate things that much. If you trade as an entity you probably have to provide an obscene amount of information to your trading platform like who are the stakeholders of the entity and who are the traders.

Not saying that SEC doesn't have sophisticated tools but I think in most cases they don't need that. Their power lies in their regulatory ability to collect personal information of who trades, when and how much.

whoisjuan··on SEC charges Netflix insider trading ring
True!
whoisjuan··on SEC charges Netflix insider trading ring
"This case reflects our continued use of sophisticated analytical tools to detect, unravel and halt pernicious insider trading schemes that involve multiple tippers, traders, and market events."

Lol, I don't think there's a lot of sophistication in this. They want to make it sound like some sort of powerful magic box they have that can find anyone doing something dubious when in reality this is probably a very simple interesection between two datasets:

The one that contains all the people who yielded profits over X amount when trading the stock of a Y company during a timeframe, and another dataset that contains all the current and former employees of that Y company.

That's the thing about insider trading. People who do it are just complete idiots. They think that they can leverage some assymetry of information when in reality there's no such thing. If you trade the stock of your current or former employer (especially before earnings calls) and yield unrealistic gains you're going to get flagged and someone is going to manually review your shit.

whoisjuan··on Launch YC S21: Meet the Batch, Thread #7
I don’t see how this solution is in a red ocean? Mature offerings where? The only non-Latam alternative that comes to my mind in this space is Checkout.com and that is just partially similar.

A provider routing middleware with the goal of increasing authorization rates is likely not even an attractive business in markets like the US and Europe where you probably can defer to a single payment provider like Stripe for maximum checkout reliability.

This is not the case in Latam. Authorization rates are way lower and anti-fraud heuristics and models by local payment providers are less sophisticated. Most growing business in Latam end up in a situation where they neeed to re-route payments to increase their authorization rates and sometimes in the need to build very strict checkouts that harm conversions but that are needed to avoid a high volume of rejected transactions.

whoisjuan··on Facebook may be forced to sell Giphy one year after buying it
We are talking about Giphy, not Facebook.
whoisjuan··on Apple's child protection features spark concern within its own ranks: sources
That’s wrong. They are also enabling on-device detection for Messages.
whoisjuan··on Apple's child protection features spark concern within its own ranks: sources
This CSAM Prevention initiative by Apple is a 180 degress change of their general message around privacy. Imagine investing hundreds of millions of dollars in pro-privacy programs, privacy features, privacy marketing, etc... just to pull this reverse card.

Of course this is going to spark concern within their own ranks. It's like working for a food company that claims to use organic, non-processed, fair-trade ingredients and in just a day deciding that you're going to switch to industrial farming sourcing and ultra-processed ingredients.

It's a complete change of narrative and there's no easy way to explain it and still defend Apple's Privacy narrative, wihout doing extreme mental gymnastics.

whoisjuan··on Facebook may be forced to sell Giphy one year after buying it
This a company that hosts and distributes GIFs. It's hard for me to see how does an acquisition of a GIF company has human rights concerns.

Even the CMA's statement is focusing solely on competition concerns.

I'm not dismissing any other potential concerns that may arise from this, but I fail to see how this isn't just a case of "FB bad so let's fuck with FB".

Someone already mentioned it here, but why didn't Google's acquisition of Tenor received similar scrutiny? Just to be clear, I'm not arguing in favor of FB or anyone. My argument is against governments disrupting free market through unfalsifiable hypotheses of how an acquisition is gonna unwind and impact the competive landscape.

In this particular case it's clear to me that financial reasoning is needed to force the reversal of an acquisition.

whoisjuan··on Facebook may be forced to sell Giphy one year after buying it
If the government forces you to reverse an acquisition of an asset that loses money in isolation, that's not just business. That's a populist government intervention without any sound financial reasoning. If Giphy had filed a Chapter 11 in the US and Company Voluntary Arrangements in the UK, to be then bought by FB, would the UK government be even scrutinizing this?

In this case this sets precedent that no other social media operation can buy Giphy. Who else could buy it and somehow make it work as a losing money asset in that case?

This is essentially the government saying: "you have to sell this back to someone but you cannot sell it to other social media companies, so you probably have to sell it for pennies to some private equity or shut it down". In what free market economy does that make sense at all?

Luckily FB can afford to lose 400MM, but what a horrible precedent this sets for the M&A activity in the tech industry.

whoisjuan··on After DeepMind’s cofounder was placed on leave for bullying, Google promoted him
Going from VP to SVP is most certainly a promotion... In this particular case, this guys was probably an L10 before his leave and is probably still an L10. In companies like Google, Facebook, Amazon, etc; an official promotion is changing levels, not titles.
whoisjuan··on After DeepMind’s cofounder was placed on leave for bullying, Google promoted him
Don’t care about this guy, but why would they think that changes in the reporting hierarchy means a promotion? If my boss leaves then I would report to my skip in the interim and in many companies that’s forever.

So just because there’s nobody between me and my skip I got promoted? That’s the most dumb rationale I have ever read.

This guy was already the head of a prominent Alphabet division. If you move him around the executive structure he could have ended up one or two skips below the CEO without that meaning absolute shit .

At that level of organizational hierarchy that’s far from a promotion. He is now the VP of some random AI program that’s way more obtuse and irrelevant than DeepMind.

The only clear public signal of a promotion at executive levels is being a VP and becoming a Chief or a SVP. That’s it. At companies like Google and Facebook changing titles doesn't mean that you got promoted. A promotion is going from one level to the next one. This guys was probably an L10 and is still an L10.

Blows my mind that they arrived to this conclusion based on such a weak signal.

whoisjuan··on Facial expression software confirms bronze medalists happier than silver
You don't need a study to understand this. Generally speaking getting silver means that you were fighting to get gold and you couldn't make it. Getting bronze means that you were fighting to be in the podium and you made it.

Again, this is a very general appreciation but it's likely the case for most athletes. In the Olympics you already know before hand who is a favorite and who is an underdog. Of course the athletes are self-aware enough to understand this as well.

whoisjuan··on DaisyUI – Tailwind CSS Components
Totally agree and I mean it with no animosity. As an adopter of Tailwind, I really want to see more of these components kits and for the exisiting ones to keep improving.
whoisjuan··on Google Translate pronounces 'rooster' in Spanish
That’s hilarious! Totally intentional.
whoisjuan··on DaisyUI – Tailwind CSS Components
I’m not saying this is ugly but the visual execution of some of these components is poor. No good usage of padding in some examples, poor ratios between the typography and the containers, inconsistent use of different line widths and border radius, weird and incosistent design choices in spacing and proportions…

I mean. This looks alright and it will certainly make any UI look pretty decent, but the execution is not superb like the actual TailwindUI library which is incredibly well thought from a visual design perspective. Those components are perhaps less shiny than these but they are incredibly functional and way more intentional.

This is a good effort though and I hope to see it improving.

whoisjuan··on TV Advertising Effectiveness and Profitability
Isn’t Credit Karma’s accelerated growth attributed to TV Ads?

I wonder why something like CK can benefit so drastically from TV Ads while others are not even close to breaking even on that investment.

Is it the quality of the ads or the nature of the product?
