jrjeksjd8d··on I'm losing the SEO battle for my own open source project
You think somebody who wrote "nanoclaw" really doesn't care about getting industry famous and improving their career prospects?
jrjeksjd8d··on Don't become an engineering manager
Titles for ICs matter for two reasons: comp, and perf reviews. At bigger companies the amount of RSUs for Staff versus Senior can be substantial. At a startup where equity is worth nothing and salaries are in a tight band anyways it doesn't make a difference.

For perf reviews your title dictates the rubric you get evaluated against, but in fact your manager is probably trying to fit a curve and then work backwards to the rubric. So they'll decide you're a 3/4 and then pick some boxes for your weakest areas to mark you down in. The realpolitik of it is that you can do the same work or more at a lower level but get paid less, depending on what you negotiate coming in, your experience, previous roles, etc.

Once you get into VP, Director, and C level they are comparable between orgs on their own kind of ladder. There's levels of responsibility for outcomes associated with being higher in the food chain. Not to say there also isn't a political aspect, but they are broadly comparable between bigger orgs.

Love to see Gunnar continuing to produce great stuff!
jrjeksjd8d··on Layoffs at Block
Square is a great option for selling crafts at a market once a month. I tried to use it for a proper multi-channel retail store and it immediately fell apart:

- the e-commerce integration (Weebly?) is very limited and the resulting sites are dog slow

- the POS itself and the backend don't work when you have hundreds of SKUs and many variants

- there's very little customization or support

My business wasn't huge but we were doing ~300k revenue annually online and in-store. We started on Square, tried Lightspeed (also garbage) and finally ended up on Shopify (best of a bad lot).

Despite making noise about "supporting small business" Shopify makes most of their money from e-commerce for giant brands. They've tried to juice returns from small customers with merchant cash advances but my sense is they make more doing professional services for big e-commerce brands

jrjeksjd8d··on A distributed queue in a single JSON file on object storage
It seems like this is an approach that trades off scale and performance for operational simplicity. They say they only have 1GB of records and they can use a single committer to handle all requests. Failover happens by missing a compare-and-set so there's probably a second of latency to become leader?

This is not to say it's a bad system, but it's very precisely tailored for their needs. If you look at the original Kafka implementation, for instance, it was also very simple and targeted. As you bolt on more use cases and features you lose the simplicity to try and become all things to all people.

jrjeksjd8d··on Tesla has to pay historic $243M judgement over Autopilot crash, judge says
The average person does not know how to fly a plane or what a plane autopilot does. It's a ridiculous superficial comparison. Planes have professional pilots who understand the capabilities and limits of aviation autopilot technology.

Tesla has had it both ways for ages - their stock price was based on "self-driving cars" and their liability was based on "asterisk asterisk the car cannot drive itself".

jrjeksjd8d··on Infrastructure decisions I endorse or regret after 4 years at a startup (2024)
I see you regret Datadog but there's no alternative - did you end up homebrewing metrics, or are you just living with their insane pricing model? In my experience they suck but not enough to leave.
jrjeksjd8d··on Microsoft says bug causes Copilot to summarize confidential emails
I think the fundamental tension is that AI produces a high volume of low quality output, and the human in the loop hates reviewing all the slop. So people want to just let the AI interface directly, but when you let slop into the real world there are consequences.
jrjeksjd8d··on Ask HN: Are there examples of 3D printing data onto physical surfaces?
FWIW I think a more precise word for what you're looking for is "fabricating". Covers machining, lasers, printing, etc.
jrjeksjd8d··on The Israeli spyware firm that accidentally just exposed itself
Even if you don't believe in the capabilities of Israeli intelligence, it's well documented that Israel supported Hamas as a hard-line alternative to the PLO to avoid a two-state solution. The Israeli right has for decades intensified the conflict to justify total war against Palestinians. Allowing a domestic attack to gin up support for aggression is in line with their behaviour for the past 3 decades.

I'm old enough to remember when Arafat was well-respected in the west and a two-state solution was the mainstream view amongst Americans. Once Netanyahu came to power in 1996 (30 years ago!) he worked to delegitimize the PLO and pursue an aggressive genocide against the Palestinians.

jrjeksjd8d··on I’m joining OpenAI
For my entire career in tech (~20 years) I have been technically good but bad at identifying business trends. I left Shopify right before their stock 4xed during COVID because their technology was stagnating and the culture was toxic. The market didn't care about any of that, I could have hung around and been a millionaire. I've been at 3 early stage startups and the difference between winners and losers was nothing to do with quality or security.

The tech industry hasn't ever been about "building" in a pure sense, and I think we look back at previous generations with an excess of nostalgia. Many superior technologies have lost out because they were less profitable or marketed poorly.

jrjeksjd8d··on Anthropic raises $30B in Series G funding at $380B post-money valuation
I've been in this situation before. Anthropic has a stupid business model but the market can stay irrational longer than you can stay solvent. If you get in there you will be aligned with people who structurally do not lose.
jrjeksjd8d··on Anthropic raises $30B in Series G funding at $380B post-money valuation
Matt Levine has put this forward in his newsletter - if you're moderately influential you can go on TV and tell people that "X industry will be dead in 10 years" because of AI and then profit from the inevitable stock dip.

Because we live in the worst possible timeline the end result for AI companies does seem to be "too big to fail", where these massive investments will get foisted on working class people via a bailout or an IPO and index inclusion.

jrjeksjd8d··on MIT Technology Review has confirmed that posts on Moltbook were fake
> That said - we have never seen this many LLM agents (150,000 atm!) wired up via a global, persistent, agent-first scratchpad

Once again LLM defenders fall back on "lots of AI" as a success metric. Is the AI useful? No, but we have a lot of it! This is like companies forcing LLM coding adoption by tracking token use.

> But it's also true that we are well into uncharted territory with bleeding edge automations that we barely even understand individually, let alone a network there of reaching in numbers possibly into ~millions

"If number go up, emergent behaviour?" is not a compelling excuse to me. Karpathy is absolutely high on his own supply trying to hype this bubble.

jrjeksjd8d··on Thought-Terminating Cliché
Do American right-wingers think "human life has value"? Why are they ok with people starving to death, or dying of preventable disease? Is human life valuable when they're an AIDS patient? Is it valuable when it's a child being killed in a mass shooting?
jrjeksjd8d··on Thought-Terminating Cliché
> Examples of such phrases might be encountered in political protests by activists. The phrases can be mainly for the members of the group particularly the call and response type.

This feels like it's aimed at leftist activism, but the American right has plenty of thought-terminating dogmas: the unitary executive, backing the police and military unequivocally, "if you don't like it here you can leave", the "original intent" of the founders. "Patriotism", the Constitution, and the American conception of Protestant Christianity are cudgels to be employed against wrong-think.

jrjeksjd8d··on GitHub Agentic Workflows
It feels like every cloud product I use is accumulating more of these peripheral features I don't want, while the core functionality is stagnant or even degrading. I'm assuming this is a Conway's Law situation where the company has to grow, and they hire more devs, but those devs can't all work on the core product so they make new greenfield stuff instead.

Until we stop chasing endless growth for it's own sake we're doomed to be stuck these enshittified products.

jrjeksjd8d··on Curating a Show on My Ineffable Mother, Ursula K. Le Guin
"The Left Hand of Darkness" was published in 1969. I'm a transgender person in my 30s and Le Guin's writing makes me emotional every time I reread it. The ideas about gender and sexuality are more mainstream than they were almost 60 years ago, but the future is not evenly distributed and I think TLHOD would be eye opening for a lot of readers. Le Guin's prose and world building also place her among the best science fiction writers of all time.
jrjeksjd8d··on A flawed paper in management science has been cited more than 6k times
Ah yes, the mythical past when nobody did bad things because we punished them correctly.
jrjeksjd8d··on How AI destroys institutions
NIMBYism is a very obvious form of "number go up". Boomers were promised endless property value growth, and they've destroyed city planning to make sure it happens. If there was a market correction retirees would be furious.

> by regressing to a past that never was despite the costs

People assume that rejecting capitalism requires us to take a step backwards. Why would that be? If you woke up tomorrow and there was more public housing your iPhone wouldn't disappear.

jrjeksjd8d··on The tech monoculture is finally breaking
Let me introduce you to... GoPro. An expensive action sports novelty.
jrjeksjd8d··on You can't pay me to prompt
My CEO sent a company-wide email this week saying "AI use is mandatory for all developers". Until this kind of mandatory bullshit stops I'm happy to see other people fighting the good fight and publicly saying that they want to keep doing a job they actually enjoy.

Many of my coworkers have embraced AI coding and the quality of our product has suffered for it. They deliver bad, hard-to-support software that technically checks some boxes and then rush on to produce more slop. It feels like a regression to the days of measuring LOC as a proxy for productivity.

jrjeksjd8d··on The tech monoculture is finally breaking
As other people have pointed out, the trend towards "retro" tech is like vinyl being popular - it's a nostalgia throwback, not a massive wave of consumer preference. There's a small but profitable niche of enthusiasts who want old electonics. Call me when a major consumer electronics company is making it a selling point that their devices are "dumb".

The Rayban-Meta partnership is such a funny thing to shoehorn in? Two giant monopolists creating a new surveillance-tech product which nobody likes. It couldn't be more "monoculture".

jrjeksjd8d··on How AI destroys institutions
Capitalism is destroying institutions. Any new technology must be employed in service of "number go up". In this system externalities have to be priced in with taxes, but it's cheaper to buy off legislators than to actually consider the externalities.

This is how we get food that has fewer nutrients but ships better, free next-day delivery of plastic trash from across the world that doesn't work, schools that exist to extract money rather than teach, social media that exists primarily to shove ads in your face and trick you into spending more time on it.

In the next 4 years we will see the end of the American experiment, as shareholder capitalism completely consumes itself and produces an economy that can only extort and exploit but not make anything of value.

jrjeksjd8d··on Ask HN: Do you have any evidence that agentic coding works?
A key thing I noticed in sincere anecdotes about LLM code is that is always seems to be outside of the author's area of expertise.

I work with an infrastructure team that are old school sysadmins, not really into coding. They are now prodigiously churning out apps that "work" for a given task. It is producing a ton of technical debt and slowing down new feature development, but this team doesn't really get it because they don't know enough software engineering to understand.

Likewise the recent example of an LLM "coding a browser" where the result didn't compile and wasn't useful. If you took it at face value you'd think "wow that's a hard task I couldn't do, and an LLM did it alone". In fact they spent a ton of effort on manually herding the LLM only for it to produce something pretty useless.

jrjeksjd8d··on The microstructure of wealth transfer in prediction markets
When you're doing extra-legal military operations in a country that isn't at war, what choice do you have? There are civilian aircraft up in the sky. Having a fighter jet run into one and kill a bunch of civilians is a bad PR situation.
jrjeksjd8d··on Amazon is ending all inventory commingling as of March 31, 2026
This is the original source, linked on HN a couple months ago: https://christopherferan.com/2021/12/25/kenya-and-the-declin...

It seems like the collective washing and grading system was effective at producing high quality coffee (but not paying farmers a living wage) until the system got so extractive and climate change got so bad that farmers cut costs and started producing worse strains. In other markets buyers would go direct to the farmers for single-origin beans to encourage higher quality but in Kenya this was prohibited.

jrjeksjd8d··on Command-line Tools can be 235x Faster than your Hadoop Cluster (2014)
I have been the first (and only) DevOps person at a couple startups. I'm usually pretty guilty of NIH and wanting to develop in-house tooling to improve productivity. But more and more in my career I try to make boring choices.

Cost is usually not a huge problem beyond seed stage. Series A-B the biggest problem is growing the customer base so the fixed infra costs become a rounding error. We've built the product and we're usually focused on customer enablement and technical wins - proving that the product works 100% of the time to large enterprises so we can close deals. We can't afford weird flakiness in the middle of a POC.

Another factor I rarely see discussed is bus factor. I've been in the industry for over a decade, and I like to be able to go on vacation. It's nice to hand off the pager sometimes. Using established technologies makes it possible to delegate responsibility to the rest of the team, instead of me owning a little rats nest fiefdom of my own design.

The fact is that if 5k/month infra cost for a core part of the service sinks your VC backed startup, you've got bigger problems. Investors gave you a big pile of money to go and get customers _now_. An extra month of runway isn't going to save you.

jrjeksjd8d··on The Dilbert Afterlife
> We are teaching the sand to think and working on 3d printing organs and peering at the beginning of time with super-telescopes and landing rockets.

There are a lot of smart and skilled people involved in making a cutting edge chip fab. It's not one ubermensch in a basement inventing a new TSMC process by thinking really hard. There's technicians, scientists, researchers in multiple disciplines. All of those people have to be organized.

I don't know where you think the "smart" people are, but maybe meditate on the fact that "smartness" is not a single variable that dictates a person's value or success. Someone who is an expert at researching extreme UV patterning isn't going to necessarily run a great chip manufacturer.

jrjeksjd8d··on The Dilbert Afterlife
The Gervais Principle is much more accurate in my experience. One of the important reasons middle management has to be "clueless" to drink the kool-aid and take on more responsibility for minimal extra compensation. The checked out employees of the world know their work is meaningless, but the clueless ascribe to it some greater meaning which makes them trustworthy.
