jmarbach··on Launch HN: Transload (YC P26) – Measuring freight items with CCTV
This is great. If of interest, please consider adding Hubble Networks's scanning gateway SDK to your devices in the future (https://hubble.com). Happy to chat privately about what incentives there may be available especially at logistics warehouses.
jmarbach··on The quiet resurgence of RF engineering
You're right, and Hubble Network (https://hubble.com) is proof. We make commodity Bluetooth LE chips talk to satellites. That required antenna design and link budget work no software abstraction would fix.

Hubble does the deep RF work so that firmware engineers building IoT devices never have to.

jmarbach··on Moving a large-scale metrics pipeline from StatsD to OpenTelemetry / Prometheus
Could you share a little more about your involvement with VictoriaMetrics? A good faith disclosure goes a long way.
jmarbach··on Sending Data over Offline Finding Networks
Hubble Network (https://hubble.com) is building something similar - an open, global BLE network.

Both let you transmit arbitrary data, but the custom setup here is a lot of overhead. Hubble gives you an SDK and lets you get back to building your device.

jmarbach··on x402 — An open protocol for internet-native payments
Anchor Browser has documentation here showing how to combine x402 with an agentic browser session.

We are not far off from humans giving a monthly allowance to their agentic counterparts.

jmarbach··on Launch HN: Trigger.dev (YC W23) – Open-source platform to build reliable AI apps
Awesome product! Although Trigger.dev is fully capable, if you want to skip installing the browser infra and offload it to a remote session, I wrote a tutorial recently on how to use Anchor Browser with Trigger.dev to achieve this: - https://trigger.dev/docs/guides/example-projects/anchor-brow... - https://anchorbrowser.io/blog/integrate-trigger-dev-and-anch...

Looking forward to tracking Trigger.dev's success in the future.

jmarbach··on The web does not need gatekeepers: Cloudflare’s new “signed agents” pitch
I recently ran a test on the page load reliability of Browserbase and I was shocked to see how unreliable it was for a standard set of websites - the top 100 websites in the US by traffic according to SimilarWeb. 29% of page load requests failed. Without an open standard for agent identification, it will always be a cat and mouse game to trap agents, and many agents will predictably fail simple tasks.

https://anchorbrowser.io/blog/page-load-reliability-on-the-t...

Here's to working together to develop a new protocol that works for agents and website owners alike.

jmarbach··on US oil lobby launches ad campaign to promote oil as 'vital' to global security
There's a term for this: an inconvenient truth.

Cheap and abundant energy is strongly correlated with prosperity. Every barrel of oil produces roughly 1,700 kWh of thermal energy. In countries with low cost of oil production like Saudi Arabia and Iran, that means electricity generation for less than $0.01/kWh. The only viable technology to compete with oil and gas over the long term is Nuclear.

jmarbach··on Dark Visitors – A list of known AI agents on the internet
I was thinking the same. Wouldn’t it be better to let agents buy access to your site? It wasn’t feasible with the Google monopoly. Now with dozens of agents competing for info it seems feasible to put a tollbooth in front of your site.
jmarbach··on Generation Junk
From The Bitcoin Standard:

"The reduction in the purchasing power of money is similar to a form of taxation... As people start spending more and saving less, they become more present oriented in all their decision making... this helps explain why civilizations prosper under a sound monetary system, but disintegrate when their monetary systems are debased."

jmarbach··on Show HN: HighContext.ai – Serverless JSON Blob Storage
When a blob is saved, first I write it to Postgres (https://neon.tech), so that ensures there's a persisting backup. However, it's typically a waste of money to store infrequently accessed blobs in disk with Postgres over months and years. After 4-6 weeks data is offloaded to object storage - so that you benefit from low long term storage costs.

The lifecycle of a blob works out roughly something like as follows, based on last read date:

< 30 mins ago

- In-Memory: Cloudflare CDN

< 30 days ago

- In-Disk: Redis Auto-Tiering Memory/Disk combination

- In-Disk: Postgres

> 30 days ago

- Object Storage: Backblaze B2

jmarbach··on Show HN: HighContext.ai – Serverless JSON Blob Storage
Yes, I agree with your point. It reminds me a little of the ongoing debate over CDN vs Edge. However, one difference we offer is that eventually our 'cache' will flush to a persistent storage layer - so you don't have to think about managing your memory or disk resources. Data not used for weeks ends up in low-cost object storage - further saving you from high-cost memory storage costs and the repetitive task of performing this archiving operation yourself.
jmarbach··on From S3 to R2: An economic opportunity
Cloudflare wrote a blog post about their bandwidth egress charges in different parts of the world: https://blog.cloudflare.com/the-relative-cost-of-bandwidth-a...

The original post also includes a link to a more recent Cloudflare blog post on AWS bandwidth charges: https://blog.cloudflare.com/aws-egregious-egress/

jmarbach··on Show HN: Agentflow – Run Complex LLM Workflows from Simple JSON
Thank you for creating this. I've been looking for something that provides a more lightweight alternative to LangChain.
jmarbach··on Continuous growth is cancer
The author is correct. Growth is typically just a debt-fueled spending binge. The cancer is actually the fiat, soft money that’s improperly aligning incentives in the economy.

People conspire to do things all the time.

jmarbach··on Snow shortage threatens Alps with wet winter season
Does Europe’s record-setting coal, gas, and biomass energy usage this winter have anything to do with this result?

jmarbach··on Europe braces for mobile network blackouts
Of course, everyone is a booster for their own cause.

The angles of attack range from the top-down to the grass roots. There are tactics for each (e.g. corrupting state leaders vs controlling mass media narratives).

jmarbach··on Why we moved from AWS RDS to Postgres in Kubernetes
$0.50 per extra GB seems high, especially for a storage-intensive app. Given the cost of cloud Object Storage services it doesn't seem to make much sense.

Examples of alternatives for managed Postgres:

* Supabase is $0.125 per GB

* DigitalOcean managed Postgres is ~$0.35 per GB

jmarbach··on Ask HN: How can I start a business to generate electricity?
Try this 25 kw gasifier to create electricity from biomass. It’s about the size of a pallet and can fit in your garage.

jmarbach··on Inflation propagates unevenly
High inflation persisted in America in the 1970s. Why wouldn’t it happen again?
jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
The Pfizer vaccine is not 90% effective. That’s a fact.
jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
In this case we should edit the title of the post to clarify, "for the variants as of x date" - agree or disagree? As to not spread misinformation.
jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
"Omicron is making it worse" is gossip to you and a fact for me. That's where we disagree.
jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
You're right. I will never question Pfizer again. There could be infinite mutations of the virus moving forward which would impact the weight of their claims.
jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
It's a fair critique. But when the Captain of an airplane I'm flying on tells me there's an emergency problem with the flaps, I don't ask him for text book evidence, I just look out at the wings and verify the problem.

jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
I am vaccinated - I believe in the early vaccine's efficacy for stopping serious illness. They have saved many lives.

What I am saying here is that the vaccines were marketed as 90% effective for preventing infection. Was I misunderstanding what was being marketed to me all along?

jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
You are completely wrong -- totally warped by the narrative.

Look at the Pfizer press release, Nov 9, 2020 - the first sentence:

"Vaccine candidate was found to be more than 90% effective in preventing COVID-19 in participants without evidence of prior SARS-CoV-2 infection in the first interim efficacy analysis"

https://www.pfizer.com/news/press-release/press-release-deta...

jmarbach··on Pfizer’s Covid-19 Pill is 89% Effective in Phase 2/3 Study
You are arguing over semantics. In reality, the Pfizer vax has proven to be less than 10% effective at stopping a future infection.
