jchonphoenix··on New California law raises minimum wage for fast food workers to $20 per hour
This is because humanoid robotics is a hard and unsolved problem. But it isn't for lack of trying.

Order taking is a simple and very much solved problem. And kitchen robotics is more assembly line esque than warehousing.

jchonphoenix··on Inflation Bites U.S. Engineering Salaries
Red/Blue politics aside, I'm fairly certain the inflationary issues you're seeing today can be root caused to loose fiscal policy from the Trump era. Biden inherited those issues and can be held accountable to fixing them, but not causing them.
jchonphoenix··on Fusion Foolery
SF still smells
jchonphoenix··on Postman acquires Akita for automated API observability
Akita has been around awhile. I remember talking to them around the time docker was still winning the container wars
jchonphoenix··on Langchain Is Pointless
Sequoia never figured out their edge in the enterprise world. They likely won't fall from grace since they're still investing in the space, but their filter is certainly poorer than their other areas of investment.
jchonphoenix··on On Dark Triads in Silicon Valley
Funny. I think I trip the filter on generally distrusting people, but not because I assume they're lying. I mostly distrust people because most people love to talk and give advice on things they aren't knowledgeable enough to be trusted on. They don't necessarily mean harm. Ray Dalio's take on this is that most individuals that give advice have low believability weighting.
jchonphoenix··on The open-source AI boom is built on Big Tech’s handouts. How long will it last?
I think you're misunderstanding my comment because you aren't reading it in context of the parent. Those are all points why big tech will be fine without open source software. I.E. if the entirety of the OSS community disappeared tomorrow, big tech would be minimally impacted. Many of the major OSS projects came from then to begin with and they already have massive efforts to maintain parallel versions. They open source tf, hack, and pytorch because it's good for recruiting. Not because it gets commits and reduces workloads. So if the OSS movement disappeared tomorrow, big tech would be the best positioned companies to keep chugging along.

Although even if all OSS software that we've discussed here disappeared tomorrow, I know at least Google and Facebook are fine because they don't use any of it. They have their own internal versions that are better and aren't shared with the world.

jchonphoenix··on The open-source AI boom is built on Big Tech’s handouts. How long will it last?
Meta uses its own php called hack. Nothing is shared with php oss. Google and Meta both have their forked versions of Cpp and python. Plus if they're closed source they will just buy it.

Pytorch and tensorflow are from FANG. Without OSS being a thing, they just keep using it without sharing it to the world.

Your examples are actually proving the opposite of your point :)

jchonphoenix··on The open-source AI boom is built on Big Tech’s handouts. How long will it last?
I've been in big tech. They rarely use anything from OSS and usually have their own internal version long before OSS has an offering. Big tech will have no problem thriving without OSS. Their business models and execution aren't reliant on it at all. They only use it for recruiting
jchonphoenix··on Stanford Alumni 5x More Likely to Secure VC Funding Than Carnegie Mellon
CMU is the same. The School of Computer Science had an an undergraduate admit rate 1 or 2% higher than Princeton when I attended. But agree that I only saw a handful of students at CMU who were accepted into MIT or Stanford. And they usually had scholarships or other reasons to attend.
jchonphoenix··on Stanford Alumni 5x More Likely to Secure VC Funding Than Carnegie Mellon
Full disclosure, I'm a CMU alum.

I think this article chose CMU because for Computer Science and technical startups, it's well understood in the valley that CMU is a top 4 school (and for many, a top 2 school) for producing software engineers, which tend to underpin a lot of tech startups.

Totally agree if you move outside of software companies that this makes sense. Anecdotally, I'll say CMU tends to produce individuals who are technically overweight but perhaps lacking in business sense. This is both because of school culture and the broader Pittsburgh community.

jchonphoenix··on Show HN: Lance – Alternative to Parquet for ML data
Hey Eddy, Arrow also allows you to serialize to disk and then utilize mmap. Compared to Parquet, the downside is that the design of Arrow makes it so storage requirements increase. If you're borrowing elements of Arrow's layout, does that not come with all the same downsides of just directly utilizing Arrow's serialization. And at that point, why not just use Arrow?
jchonphoenix··on Launch HN: Infield (YC W20) – Safer, faster dependency upgrades
I don't think you'd print money just by telling people if a dependency is hard or easy to install though. You'd need to actually solve the problem of getting the dependency installed or suggesting some alternative solution that gets the code written.

E.g. if I'm banging my head against a wall trying to upgrade to the newest version of PyTorch for some graph embeddings feature and everything breaks, knowing it's high risk doesn't help me. I still need to get the thing installed so I can use the feature.

jchonphoenix··on Meta stops offering remote work in new job postings
I'd love to see it too, but don't you think the sentiment is a little entitled?

Meta is a private company that can do whatever it wants and Zuck doesn't need to justify anything. He's also not being too egregious here. He's stopped hiring new remote, but hasn't forced any current remote people back into the office. What right do we have to demand more from them?

jchonphoenix··on Meta stops offering remote work in new job postings
This isn't as nefarious as everyone makes it out to be. There are articles that state Meta has hard data that people who start as Remote workers at Meta significantly underperform those that don't. In light of that data, they're pausing the experiment and working to understand what the data is saying.
jchonphoenix··on Block's Response to Inaccurate Short Seller Report
This sounds eerily like the same response the SVB & Lehman CEO gave right before they went under.
jchonphoenix··on Oxide pays all employees $191,227 (Bay Area startup)
I'm curious how they make this work in sf unless they own a home or bought a long while back.
jchonphoenix··on Ask HN: What moonshots do you wish were being attempted?
Affordable housing
jchonphoenix··on Amazon staff might get paid 50% less because shares have fallen so much
Unfortunately not. I just interviewed around for VPE roles at Series B companies, and they aren't even able to be competitive with non-Director compensation at FAANG.
jchonphoenix··on Meta Reports Fourth Quarter and Full Year 2022 Results
What I've come to realize is that everyone likes to say they stopped using it, but the reality is that they actually do still use FB. They just aren't as active posting their own updates. But they are engaging in the platform, comments, etc. FBs got a long way to go before the golden goose is actually at risk.

Younger people not using FB though seems pretty real.

jchonphoenix··on Ask HN: Is there a recommender system for blog posts or articles?
I think you're technically on one of them
jchonphoenix··on New blood test can detect toxic protein years before Alzheimer's symptoms emerge
Does this mean prions cause alzheimers?
jchonphoenix··on Ask HN: How do you start a startup in your 30s when you have wife/kids/mortgage?
Any pointers on how it's simple to start a lifestyle company? I've always been venture backed so breaking into a market for a lifestyle business seems just as hard to me
jchonphoenix··on Carvana to cut 1,500 jobs as online auto dealer’s troubles mount
Carvana likely has very few engineers. Most of the employees are in operations facilitating car purchasing, inspecting, pricing, etc.
jchonphoenix··on A Six-Figure Income Is Needed Just to Afford the Typical US Home
Keyword: most.

In San Francisco, 100k qualifies you for governmental support services like low income housing.

jchonphoenix··on Stripe laying off around 14% of workforce
Stripe has barely trimmed their internal valuation. Their best public comp, Square, has lost 80% of it's market cap since the peak. Stripe on the other hand, has trimmed theirs 22%. The people most hurt by this are employees at refresher and offer time given their yearly vest schedule.
jchonphoenix··on Meta Earning Results Q3 2022 [pdf]
Actually, everyone is underwater on RSUs. We do 4 year vesting so even people who started 5 years ago are vesting their stock from 4 years ago.
jchonphoenix··on Apple’s ad business set to boom on the back of its own anti-tracking crackdown
Apple has access to all data it blocks from other ad networks by virtue of you owning an iPhone. It uses this data in its DSP. One effect of Apple locking down privacy was to create a unique monopoly on data for itself and its an advantage it intends to capitalize on.

California forgot it doesn't have any usable public transit.
