I am also not a therapist but I am a former tech founder turned executive coach so I do talk to people who are facing what feels like overwhelming challenges, risk, and uncertainty.

Even in the language you used "severe learned helplessness" and "extremely stupid", you are revealing a state of mind (cynicism, self-flagellation) that is not oriented to improving your condition.

You know you have a strong bias against therapists—given your seeming lack of knowledge about them, where do you think that bias came from? Fundamentally, we are a social species and evolved to live with strong connections to small groups.

Our society is no longer set up like that. So professionals like therapists and coaches provide the essential value of a caring, supportive, and helpful relationship that we lack. Like getting an essential nutrient that your diet lacks.

Do you have health insurance? Many of them cover mental health—the site Headway can help you find one that takes insurance. Try a few and gather some first-party data before writing them off fully. The downside is a few hundred dollars. The upside is a much brighter and materially better future.

Quite a few radios are direct-- no intermediate frequency, just a set of band selection filters. The direct route does not quite hit the absolute state of the art in dynamic range, but it's close. IC-7300, IC-7610, Elecraft K4, etc. all have this design. I wouldn't be too surprised if one more generation of ADC improvements take it over the line. Certainly there is a lot more engineering might being put into better ADC designs than there is for superhet radios.

Beyond being simpler on the analog side the direct conversion route makes spectrum/waterfall views of the whole band trivial. In theory radios could use this wide bandwidth for improved impulse blanker performance, but I'm not sure which if any do.

Some (like the flex radio, and Elecraft) will do multiple in-one-band simultaneous receive with on each ADC using it... but (other than flex perhaps) the advantages of direct converting a whole band are currently under-utilized. Once they are I doubt there will be much interest in superhet even if the dynamic range isn't quite matched.

I think the future of radio designs though will be finding ways to move the RF portion closer to the antenna(s), away from RF-noisy buildings, and avoiding expensive, lossy, and annoying coax runs.

The number of electors has been effectively fixed since 1927. It's unlikely to change in this highly polarized environment. Any increase in electors would reduce Republican power. If Canada comes in as the 51st (singular!) state all that would happen is New York California, Illinois, Texas and Florida would all get fewer electors (House seats).
If you're streaming something row-based like a CSV, or a zipped CSV, then that's usually easy.

But when you get to hierarchical data structures like JSON/protobuf there very often simply isn't a streaming library available. There's a library function to decode the whole thing into an object in memory, and that's all.

Nothing prevents streaming in theory, it's just far more complicated to write that library.

> an AI-powered programming practice where a programmer surrenders to the "vibes" and power of the AI, while ignoring the details of the generated code.

if you're working on a personal or hobby project, do whatever you want. let your cat sleep on the keyboard, feed that into DeepSeek, and pipe the output directly into `git commit -am 'lol vibes' && git push --force` if you want.

if you're working professionally, by all means use whatever tools you find useful. the only thing that matters is the finished product.

however, if I'm your coworker, that finished product is a pull request that has your name on it. if I'm reviewing it, I expect you to be able to answer questions about the details of the code. after it's merged, it's getting deployed to production, and I'm in an on-call rotation that can wake me up at 2am if it's broken.

if I ask a question about some detail in your PR and your answer is "I dunno why it's that way, the AI wrote the code based on vibes and I ignored the details" I am going to have to have an uncomfortable chat with you and/or your manager.

details matter. ignore them at your peril. the fanciest tape measure in the world does not relieve a carpenter of the need to "measure twice, cut once". an LLM is likewise just a tool you can use. it does not remove the need to think about the details.
That's unfortunate. Still not even remotely comparable to Auschwitz.

Hi,
We built this over the course the last 4 months. We hated misinformation, we hated bots, we hated loneliness, we hated corporate infiltration, we hated the destruction of our kids' mental health.

Requester Mode -> Create and activate Requests to be sent and seen by anyone in "Responder Mode"

Responder Mode -> Respond to active Requests that get sent your way. You can filter requests by maturity, creativity and some safety stuff. More clever filters in future.

Observation Deck -> Watch the most interesting conversations happen. We're still building this.

We wanted an operating system type feel. We went with window management as we thought this was the most intuitive.

We're running with this tagline for now: "A next-generation social platform that connects people through real time conversations." but we think it's corny and want a new one; suggestions welcome.

Have a great Thursday HN! It's a privilege to be here. -Brandon
Now I'm curious about how this worked in my city where we most definitely didn't have anything digital to our phone system at the time. As in, you had to use pulse dialing, and sometimes, rarely, your calls would glitch such that you would hear someone else talking over your call. Yet I remember consistently getting 40-something kbit over that.

Show HN: MiniCode – Learn how to build your own Next.js
We want to make contributing to open-source easier, especially when dealing with complex, large-scale codebases. To help engineers better grasp the technical workings of these projects, we've created MiniCode—a set of mini-repositories that replicate essential functionalities of larger codebases in a simpler form.

We're starting this initiative by launching a mini-repo focused on Vercel's Next.js. This mini-project aims to offer a hands-on, practical approach to understanding Next.js internals and structure.
We've observed that engineers often struggle with onboarding onto large codebases because passive documentation doesn't always provide the needed clarity. Actively building or exploring smaller, MVP-like versions can significantly improve comprehension, encouraging engineers to become more versatile and generalist in their skills. This philosophy drove us to develop MiniCode.

We would genuinely appreciate any feedback, insights, or suggestions from the community as we continue to build out mini-versions for other prominent open-source projects in the future. Let us know if it was helpful for you or any changes that you would like to see!

The French arisocracy mostly survived the Revolution not only with their lives but also their riches. Those that lost lands partly had them restored under Napoleon and the Bourbons. The degree of their survival is so great that it's debated whether the nobility benefited from the Revolution [1].

Today's rich and their wealth are more mobile. Idiots fantasising about violent revolution are mostly digging their own graves or playing into the hands of oligarchs unhappy with the democratic status quo.

"Hadoop’s meteoric rise led many organizations to implement it without understanding its complexities, often resulting in underutilized clusters or over-engineered architectures. Iceberg is walking a similar path."

This pain is too real, and too close to home. I've seen this outcome turn the entire business off of consuming their data via hadoop because it turns into a wasteland of delayed deliveries, broken datasets, op's teams who cannot scale, and architects overselling too robust designs.

I've tried to scale down hadoop to the business user with visual etl tools like Alteryx, but there again compatibility between Alteryx and hadoop suck via ODBC connectors. I came from an AWS based stack into a poorly leapfrogged data stack and it's hard not to pull my hair out between the business struggling to use it and infra + op's not keeping up. Now these teams want to push to iceburg or big query while ignoring the mountains of tech debt they have created.

Don't get me wrong Hadoop isn't a bad idea, its just complex and a time suck, and unless you have time to dedicate to properly deploy these solutions which most business do not, your implementation will suffer, your business will suffer.

"While the parallels to Hadoop are striking, we also have the opportunity to avoid its pitfalls." no one in IT learns from their failures unless they are writing the checks, most will flip before they feel the pain.
What would be found here in a thousand years much less a million?

My attitude is that it's something similar to getting ready for the end of the world by putting money in a savings account. If the money (or gold under your bed, cans of beans in the basement or even a pistol in your nightstand) does any good then it's not the end of the world.

If the universe is so crowded or so good at finding things like voyager that it's found in a meaningful (i.e. before humanity goes extinct or joins the godhead) time frame then we would have that encounter if voyager existed or not.

Show HN: C++ AWS MSK IAM Auth Implementation – Goodbye Kafka Passwords
In 2023, AWS announced[1] IAM authentication for MSK Kafka clusters with support for "all programming languages"… except C++. While Java[2], Python[3], Go[4], and others got official SDKs, C++ developers/vendors were stuck hardcoding SCRAM-SHA credentials in code/configs or relying on heavier Java-based tools like Kafka Connect or Apache Flink.

Later, community projects added Rust[5] and Ruby[6] support. Why no C++? Rust might be the new favorite, but C++ is still king for high-performance data systems: minimal dependencies, lean resource use, and raw speed.

At Timeplus, we needed IAM auth for our C++ streaming engine, Proton, so we built it ourselves. Today, we’re open-sourcing our code for AWS MSK IAM authentication. It’s live in Timeplus Proton 1.6.12

Just attach an IAM role to your EC2 instance or EKS pod, then put the Timeplus Proton single binary inside, start the server, then run the following SQL to read or write MSK:

CREATE EXTERNAL STREAM msk_stream(column_defs)
SETTINGS
type='kafka',topic='topic2',
brokers='prefix.kafka.us-west-2.amazonaws.com:9098',
security_protocol='SASL_SSL',
sasl_mechanism='AWS_MSK_IAM';

The core logic is just two files under 200 lines and you can reuse the code anywhere.
https://github.com/timeplus-io/proton/blob/develop/src/IO/Ka...
https://github.com/timeplus-io/proton/blob/develop/src/IO/Ka...

We’d love to get your feedback and work together to make this a standalone library—or even get it into ClickHouse or AWS SDK for C++.

For those curious about Timeplus Proton: it’s an open-source streaming engine we built in C++ (think “FlinkSQL in C++” meets ClickHouse’s columnar storage). Later this month, we will also open-source our C++ code for Apache Iceberg read&write. Stay tuned.

The idea of prosperity gospel is strong in the US, it doesn't take much more than looking at US elections and seeing the religious poor voting for Trump and using "because he is rich" as one of the reasons for it.

This also ties into Milton Friedman's "everyone runs on greed" idealisms that permeate capitalism.

I think some of this is because you don't live in the US and get to see behavior like this daily.
re: real world implications, LLMs and VLMs aren't magi, and anyone who goes in expecting 100% automation is in for a surprise (especially in domains like medical or legal).

IMO there's still a large gap for businesses in going from raw OCR outputs —> document processing deployed in prod for mission-critical use cases.

e.g. you still need to build and label datasets, orchestrate pipelines (classify -> split -> extract), detect uncertainty and correct with human-in-the-loop, fine-tune, and a lot more. You can certainly get close to full automation over time, but it's going to take time and effort.

But for RAG and other use cases where the error tolerance is higher, I do think these OCR models will get good enough to just solve that part of the problem.

Disclaimer: I started a LLM doc processing company to help companies solve problems in this space (https://extend.app/)
It's not about harder but about what error you can tolerate. Here if you have accuracy 99% for many applications it's enough. If you have 99% accuracy per trip of no crash during self driving then you gonna be dead within a year very likely.

For cars we need accuracy at least 99.99% and that's very hard.

Trust me, us Europeans are not exempt from the "everyone should see a psychologist" trope blasting social media the last decade. We are not blind to every Hollywood actor having a personal therapist either.

I think the main difference (speaking as a northern European) is that when you Americans speak of therapy you seem to mean the stereotypical "talk therapy" where as basically every therapy here is cognitive behavioral therapy.

Can cognitive behavioral therapy help someone who has a bit of existential dread about his tech job? Maybe. I don't think it's silly on it's face though to say "really?" if the poster's life is in order otherwise.
No. But it's on the same trajectory.
