I like this quote:

> First time founders are obsessed with product. Second time founders are obsessed with distribution.

I have personally grown an app from zero to 100k+ users, with no marketing budget. I don't have a magic formula, but i can say in hindsight that the first 5 users were harder to get than the next 999,995.

Here was my secret: I begged. Finding 5 people to actually use my product was soooo freakin hard. Once I got to ~100, organic growth started to take over, but things like responding to emails, fixing bugs and looking into new features right away make early users personally like you and more likely to tell their friends.

The hard part is finding the right people at the right time. I googled "Persona email scheduling" and found https://usepersona.app/, so I'll assume that is you. I don't know much about your product, but i assume you are targeting people who need to schedule lots of meetings. I have a few notes:

1) Your pricing is crazy. $660/year is a lot for automated meeting scheduling. Your comp should be Calendly which is closer to $10/month.

2) What problem are you trying to solve? Calendly seems pretty close to the perfect solution for one-on-one meetings. This seems to be for scheduling larger groups. Make that clear at the top of the page. If you are directly competing with Calendly, then just make that clear.

3) I'm not the audience, but think about who really has this problem. For me, 90% of my group meetings are scheduled within my company and we use Google calendar to find times that work. I dont do this enough that I'd feel compelled to try out a new product. Sales people schedule lots of 1-on-1 calls, but not sure that group calls is a big issue. So think about who this is really for. In general, just about the only time i will try a new product is if it provokes my curiosity (not gonna happen for a meeting scheduling bot) or it is solving a problem I need solved right now. Some products are really great, but finding the right person at the right time is a huge challenge. This is why I brought up the quote at the beginning. The right product with no distribution is very hard to get off the ground. I'd say that your early goal should be to find power users if possible... if you try to spread too wide of a net, you will probably fail. Better to have a few people who love your app than a larger group of people who think it's nice.

4) Let's say you do get a few users. Well, you are an email scheduling tool, so distribution is actually built on. On your free or basic plans, you can have a banner at the bottom of outgoing emails that says "This email was drafted by Persona, the tool for automated emails". Now you have free marketing on every email that goes out. Same way that my calendly link is free marketing for calendly. If people want that banner removed, they can upgrade their plan.

Again, take this advice for what it's worth, which is very little, since 1) I dont know your market well, and 2) what worked for me may not work for you.

> Boring Company has actually built tunnels and passengers are actually riding it. No one else is even trying.

Boring Company bought an existing tunnel boring machine (TBM), and used it to dig a car tunnel. Their only “innovation” in terms of any cost savings is to dig smaller tunnels - which we already knew could be done (tunnel cost grows with diameter), and which we don’t do for good reasons (capacity, emergency egress).

The branding and marketing exercise was excellent though.

Of course it isn't "too big to fail". Even banks aren't. Despite recent history large banks have failed often throughout history. There's no such thing. It may take down the supporting sovereign government (Dutch East Indies) but life goes on and new political orgs appear. People be people.

Too big to fail is a very recent modern myth. Go back 100+ years and lots of banks failed leading into the Great Depression.

Every system has a break point.

It's an opinion piece from a former Square exec, Aaron Zamost. He writes: "... when the job market is tight, hiring top talent can be nothing short of a matter of survival. And they are fishing in a largely progressive pond ... what did companies do when a generous compensation package was no longer enough to win over candidates? They instead sold a sense of belonging ... A new economic reality following the height of the pandemic ... Because they no longer needed to compete for labor at any cost, executives exhausted by their formerly empowered employees were happy to take back the control that they’d ceded ... The recent reassertion of managerial prerogative was only possible in an economic environment where top executives could flex their muscles like a boss."

There are a lot of people on "both sides" who choose their positions on the issues to fit their political party as opposed to choose the party that fits their positions. Particularly for an issue like offshore wind or Keystone XL that is basically "out of sight and out of mind" there are millions of people who would change their position if the right people told them to.

> A former NASA engineer with a PhD in space electronics who later worked at Google for 10 years wrote an article about why datacenters in space are very technically challenging

It's curious that we live in a world in which I think the majority of people somehow think this ISN'T complicated.

Like, have we long since reached the point where technology is suitably advanced to average people that it seems like magic, where people can almost literally propose companies that just "conjure magic" and the average person thinks that's reasonable?

> he is counting every c file in the systemd _repository_ which houses multiple projects, libraries and daemons. he equates that to the c file count for a single init. it's a disingenuous comparison.

See, this is why when I refer to the Systemd Project, I spell it as "SystemD", and when I'm referring to systemd(1), I spell it "systemd". I understand that some folks who only wish to shit on the Systemd Project also spell it that way, but I ain't one of them.

> systemd-init is a small slice of the code in the systemd repository.

Given the context:

Yes, systemd provides a lot of capabilities, but we will be losing some things I consider important.

I'd say that the topic of discussion was SystemD, rather than systemd. systemd doesn't provide you with all that many capabilities; it's really not much more than what you get with OpenRC + a supervisor (either supervise-daemon or s6).

> grid storage favors sola

In what way?

> Solar can be placed much closer to consumption, literally on the roof of the consumer. Wind exists in large farms away from cities.

You still need the grid to exist, so 100 miles one way or the other doesn't affect cost very much.

> Then, when the nimby people are no longer in power, we bring back wind.

NIMBY never goes away. There are some situations where you don't want to burn up your political capital fighting them, but in general if you can get a project through then do it.

She is in the news a lot right now. I couldn't really understand why her involvement in the investigation of voter fraud in GA is a story until I read that it is really strange that she, as DNI, is involved in an FBI investigation. That's very unusual for a person in her post, right? The story as I understand it is that she is doing Trump's bidding, because otherwise she would have no place participating in this investigation. Did I get it right?

Technical analysis most definitely can be biased due to political leanings. This is why there is the whole idea that research can often be bought and paid for to get the results you desire. Because they are biased with money. Certain ideas or theories of how things could be done could very easily be overlooked or excluded by someone trying to dig for reasons to say something won't work.

What I am saying is that clearly SpaceX/xAI feel that this is a viable option based on many experts research/facts that are more knowledgeable than a single bloggers opinion. If I am thinking rationally why would I choose to believe a single random person over a group of experts banking A LOT of money that they have a solution that works?

Parking exists in cities that are transit-first. But you are living in a car-dependent city for most things, so obviously it’s not going to be as convenient: the city isn’t built to be livable without a car. More developed countries put the amenities with the transit. IE your kids school has a metro stop named after it, and the grocery store is also the subway station.

It’s unfortunate that NA developed the wrong way because it takes a while to repair stupid planning decisions

Introducing Nia Vault, a CLI that lets you query your local markdown/text files using natural language.

What it does:

Semantic search over local folders and notes
Works across multiple synced directories
RAG-style answers with citations from your own files

How it works:

Calls `POST /search/query` with `local_folders`
Uses `search_mode: sources` to return answers + file references

Example:

vault ask "What are my notes about project planning?"

Interesting! Been building space-time coordinate system for AI models. Notionally agree in principle w.r.t. convex hull, clocks, etc. since we invoke similar machinery albeit in tokenized models. Need read this work more deeply to grok.

One question is to what extent you dig into or have considered oversampling? One of the core hypotheses we've converged on is that nearly all models are optimized for source coding vs. channel coding. The implication is path to AGI likely involves oversampling to capture channel coding gains and which will resolve phase errors, etc.

Random sampling naturally does this albeit inefficiently. Curious if you do something more structured than random in terms of oversampling and especially partial overlapped samples / think supersaturated subspaces / subchannels, etc.

It's worth noting that the EACTS can at maximum dissipate 70kW of waste heat. And EEACTS (the original heat exchange system) can only dissipate another 14kW.

That is together less than a single AI inference rack.

And to achieve that the EACTS needs 6 radiator ORUs each spanning 23 meters by 11 meters and with a mass of 1100 kg. So that's 1500 square meters and 6 and a half metric tons before you factor in any of the actual refrigerant, pumps, support beams, valve assemblies, rotary joints, or cold side heat exchangers all of which will probably together double the mass you need to put in orbit.

There is no situation where that makes sense.

-----------

Manufacturing in space makes sense (all kinds of techniques are theoretically easier in zero G and hard vacuum).

Mining asteroids, etc makes sense.

Datacenters in space for people on earth? That's just stupid.

> If you want to go down the value chain, then by definition the less valuable the software is and the easier to be commoditized.

I'm not sure that holds for what we're talking about - high-value software can afford to be somewhat flaky because it delivers enough value when it works to make up for it, software that's only marginally worthwhile needs to be reliable because if it isn't then it's not worth the bother. Commoditized fields are more competitive.

> The automation is not going to help just the manager-turned-vibecoder, it's also going to help professionals to create FOSS alternatives that can be robust enough.

Not convinced. In my experience these tools don't really help with creating high-quality software. Maybe they'll get there eventually (at which point we're all out of a job), but right now they can't "hit the high notes".

> Take California’s high speed rail. Every individual has the right to object. No one wants an eyesore in their backyard. Everyone gets a hearing. Everyone gets a lawsuit. Everyone gets a veto in practice, if not in theory.

If there was actually freedom and you wanted to build high speed rail, you would solicit investors, go negotiate for some land -- the power company has a bunch of transmission lines up the coast that run approximately parallel to the highways, maybe get that land, your trains were going to need power anyway -- and then you hire some people and start laying tracks.

"Everyone gets a veto" is the thing where you can't do it because the government won't let you even when you have the wherewithal and inclination to do it. That's the opposite of freedom.

I take long-term stewardship of software systems for companies where internal software has become mission critical, but ownership of those systems is diffuse.

I'm a good fit for companies in the $25M+ annual operating range who can't afford unstable systems and need a reliable, responsible party to oversee long-term operations and development.

Our mission is to make it normal, not heroic, for edge AI, mobile apps, and critical software to run close to where data is born: on devices, in vehicles, in field hardware, not just in a distant GPU farm. We’re building the data and trust layer that lets developers ship systems that still behave correctly when links are flaky, latency is awful, and the cloud is optional instead of mandatory—instead of the usual “SQLite everywhere + ad-hoc sync” duct tape.

I'm lucky that (1) there is one place that offers therapy in my town in 2026 (all the rest of them went out of business in in the pandemic), (2) my insurance will pay for it, and (3) my therapist endorses foxwork.

Just recently, to the great relief of my wife, I developed a "cover story" that explains it all rationally and it's a lot easier to get help from humans like personal trainers, hairdressers, voice coaches, etc. Still I have good discussions with Copilot that help me refine character adjustments and such.

For transforms, the concept would be user friendly processing, like downcoding video & photos, compressing PDFs & text files, filtering out temporary or wasteful files . Something like AirTable for backups with a gui workflow editor with common processing jobs for backups.

For indexing, full text indexing of backups to allow for record retrieval based on keyword or date. E.g. “images in Los Angeles before 2010” or “tax records from 2015”. If possible, low resolution thumbnails of the backups to make retrieval easier.

I think #1 (transforms) would be more generally useful for cross cloud applications, and #2 is more catered toward backups

The distinction is that what they are doing for Webb is trying to dissipate small amounts of heat that would warm up sensors past cryogenic temperatures.

Like on the order of tens or hundreds of watts but -100C.

Dissipating heat for an AI datacenter is a different game. A single AI inference or training rack is going to be putting out somewhere around 100kW of waste heat. Temps don't have to be cryogenic but it's the difference between chiselling a marble or jade statue and excavating a quarry.

I had the option to get a "Real ID" the last time I renewed my driver's license, and did not. I forget which stupid bit of paper gave me trouble, but I had a valid passport (the Mother of All IDs), which was both insufficient to get a "Real ID" and sufficient to fly. It's a joke, a nuisance, and now a revenue source.

Cool concept! The agent-to-agent communication space is heating up.

Curious about the security model here. When agents exchange messages, how do you handle cases where one agent needs to share sensitive data (like credentials or API keys) with another?

We're building a password automation agent (thepassword.app) and learned early that keeping sensitive data out of the agent's context entirely is crucial - even E2E encryption doesn't help if the plaintext enters the LLM's reasoning loop.

Would be interesting to see if dm.bot could integrate with secret management for agent workflows.

Elon put everything he had into spacex and tesla. Against all odds, both worked out. He's now betting tesla on optimus.

> If two people disagree on whether something is funny, who's wrong? You can't say either of them is. There's no reward function for funny.

Laughter is the reward. N of 2 is a small sample size, but if one person laughed you could say it was 50% funny.

> a really good joke is recent, relevant, and shows deep understanding of its subject

These can help, but it ultimately doesn't matter how recent, relevant, or deep a joke is. If no one laughs, it wasn't funny.

Thank you for the profound insight. I completely agree that the path to AGI lies in channel coding (robustness and synchronization) rather than just source coding (compression).In CSCT, we don't just "sample" data; we process it as a continuous Projected Dynamical System. Here is how we address your points:

Structured Temporal Oversampling: Our stream-based approach effectively performs high-density oversampling in the time domain. Instead of random sampling, the theta-phase (hippocampal rhythm) in our MultiGate architecture creates structured, overlapping "integration windows" to capture temporal context.

Phase Error Resolution: Phase errors are resolved not by averaging (as in L2 models), but by NMDA-gating. The gate only opens when the anchor velocity and theta-phase align, physically "locking" the signal to a specific codebook vertex. This is a computational implementation of theta-gamma coupling.

Supersaturated Subspaces: Our Simplex constraint (L1) naturally handles what you call "supersaturated subspaces" by enforcing non-negative competition. This ensures that even with overlapping temporal samples, the resulting internal representation remains discrete and grounded within the convex hull.

By treating cognition as a communication channel between an "Anchor" and "Codebook," we prioritize the stability of the compositional mapping over the mere efficiency of representation.

> Every additional "right" you have is a "freedom" you can choose to execute or not execute on. A right is an additional freedom. If you have no rights, you have no freedom, if you have unlimited rights, you have unlimited freedom.

Suppose there is one city where everyone has the right to build new housing on any piece of land they own and another city where everyone has the right to prevent anyone else from building new housing. These things are the opposite of one another, so they can't both be increasing the "freedom" of the public at large.

Now which city actually has more freedom?

> I, too, dislike walking far. Here’s how I faked my way into a handicap parking tag.

Cute analogy, but.

Handicap parking tags provide value to those who need them. Depriving them of parking makes their lives harder.

On the other hand, TSA is pure theater, as TFA makes clear. Avoiding this needless ritual saves time for the passenger, for the TSA officers, even for the other passengers, and does not increase risk at all. It's pure win-win.
by Fhch6HQ | 2026-02-03 03:25:27+00:00
That's a really disappointing source. The headline is '200,000 people a day fly without REAL-ID', which starts out quite interesting.

It then goes on to explain that the TSA has reported 93% of traveler's complied with REAL ID, citing a TSA blog from a week prior which in fact states the same.

They then take this and couple it with a single day, which they state was the busiest travel day of the Memorial Day weekend, and extrapolate that 7% of the travelers that day must've failed to provide a REAL ID.

For the sake of conversation, this is a reasonable statement. Going back and using it to suggest 200k fly without it on a typical day is not reasonable, nor is your suggestion that a 6 months later it's still at 7% (or even typical travel volume hasn't changed.) There has to be better data available.

I was curious about this, so I looked up travel volume. YTD the daily average is 2,130,136 passengers. At 7%, this is 149,109.5 passengers or $2.449 B a year in fees. This ignores that you only pay the fee once very 10 days and assumes that all travelers pay the fee on every occurrence.

Annex Risk | Backend + Data Engineer | Bay Area, Austin | Full-time

The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.

We grew 4x in 2025 and anticipate similar growth in 2026. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.

We're in that exciting early stage, where someone can contribute foundational new pieces to core parts of our platform.
