robcohen··on Declining Fertility Rates
Isn't that their job though? To find market opportunities for providing value by solving problems people have (or think) they have?

So on some level, it's literally their job to find solutions for problems.

robcohen··on As Android developer verification gets ready to go, a new reason to be worried
Honestly, for people who value privacy and security: What exactly is the plan?

It seems like we're going from a reasonably acceptable option (GrapheneOS), to nothing.

robcohen··on Top model scores may be skewed by Git history leaks in SWE-bench
Aren't there only two rules that all groups follow in the animal kingdom?

- don't lie too often

- don't kill members of the in group

Seems like these would be required for any group to survive, which makes sense why they are universal. All other rules/ethics seem to be dependent on resource scarcity.

robcohen··on Ask HN: Why are so many services rejecting Google Voice numbers for signups?
True, but the original sin was using phone numbers as proof of identity. The fundamental problem is average users cannot use passkeys, manage their own crypto keys, or understand that for identity to work, there cannot be an authority based recovery method.

The market simply does not care, and businesses are acting accordingly and picking the lowest friction option with acceptable levels of fraud.

What’s odd to me is that they dont even have a method for more advanced users to not use numbers. I think perhaps Digital Credit Union may be the only bank in the US using passkeys.

robcohen··on Show HN: lambda-nat-proxy – Serverless proxy using Lambda and UDP NAT punching
I'm not trying to disparage the attempt, just thinking of a way to make it's end goal more agnostic and efficient.
robcohen··on Show HN: lambda-nat-proxy – Serverless proxy using Lambda and UDP NAT punching
Sure, I think it's an awesome effort. Just trying to think of an agnostic approach that's more efficient.
robcohen··on Show HN: lambda-nat-proxy – Serverless proxy using Lambda and UDP NAT punching
Alternatively, you could make a Nix flake that can generate an immutable microVM image based on Solo5, running a MirageOS unikernel that implements NAT traversal with UDP hole punching and relay fallback. This image can be deployed to Fly.io as a lightweight, autoscaling Firecracker VM with per-second billing. It boots in milliseconds and costs far less than Lambda.

Any reason to use lambda vs this cloud-agnostic approach? Maybe I am missing something. I guess per second vs per 100ms billing, but I can't imagine it ends up being cheaper with Lambda.

robcohen··on Drinks in glass bottles contain more microplastics than those in other container
I don't get this. If paint is causing the problem, why not just stop painting the caps.
robcohen··on U.S. sanctions cloud provider 'Funnull' as top source of 'pig butchering' scams
KindHearts for Charitable Humanitarian Development v. Geithner and Al Haramain Islamic Foundation v. U.S. Department of the Treasury
robcohen··on My TV started playing a video in full screen by itself. What happened?
One super annoying issue I've found is that if you enable Smartthings on Samsung TVs, and you try to use your phone app as a remote, they ask for microphone access EVERY TIME I USE THE APP. The options are "Enable" and "Cancel". I click cancel, the remote works for 3 minutes, then stops working and I have to force restart the app and do it again. All for a feature I use if I can't find my physical remote.

Seriously. I hate these companies with a passion. It's crazy that right now the only alternative is to not use smart features / wifi. There's not even a good Android TV option. The best I can do is just run VLC on a computer connected to the screen (Kodi has an awful UI/UX, in my opinion). Plex used to be good before they became awful. AppleTV is the only semi-decent device, but it requires a iCloud login.

robcohen··on Congestion Pricing Is a Policy Miracle
Miracle seems to imply that the outcome is not what one would expect when pricing rise. Demand goes down when prices go up, and alternatives get used more frequently. This is precisely what anyone who understand economics would think. Why is this surprising or miraculous? Is that tongue-in-cheek?
robcohen··on The 2005 Sony Bravia ad
While your point has value, there's also value in the perspective that people should take more responsibility for the damage inflicted on others under their watch. For example, it is my perspective that too many people stood by idly while the U.S. engaged in war for the 90's/00's/10's/20's. Too many people said "I want to go make money on wall street/in law/in consulting" instead of either changing their political system or serving it. There is a fair argument that war, particularly war conducted by your own country, is an exceptional thing and requires re-prioritizing duties over desires. The only other exception I can think of that isn't debateable is genocide.
robcohen··on Create a QubesOS Gaming HVM with GPU PCI passthrough (2023)
While it is possible and very cool to do PCI pass-through for GPUs, a huge problem with this approach is that online games have anti-cheat that checks to see if the game is running in a VM. So games without that mostly games that are single player will work but anything networked will likely not.

While it’s absolutely possible to play the cat and mouse game where you beat the Anti-cheat engine, It’s frankly an awful lot of work for such little benefit. You’re better off just using the service like GeForce Now Or something similar for networked games.

robcohen··on Austin rents have fallen for nearly two years
One correction:

Change "Build more housing" to "Increase supply of available housing". Those are distinct. There is a LOT of unused housing that sits empty. If you changed the incentives a bit, that housing would not sit empty, and thus the supply of available housing increases.

robcohen··on 1 in 5 online job postings are either fake or never filled, study finds
Yes, you can absolutely add a middle man to sort through the spam for you, and that "solves" the problem in the sense that you are trading money for time. It's no different than paying for a personal assistant to collect your mail for you and pass along the valuable stuff. That said, it's incredibly inefficient and most people, for most interactions, cannot hire a third party to handle those interactions for them.

So no, I don't think adding layers of middle men really solves the problem for most people.

robcohen··on 1 in 5 online job postings are either fake or never filled, study finds
This is a spam problem. Spam problems are easily solved by simply charging for attention. Job postings should pay me to view them, and I should pay job postings to apply to them. The only reason why ghost postings exist is because the marginal cost to the company is so incredibly low to do it.

In demand people should get paid for their attention.

What I don't understand is why are there no systems that actually implement this? Most likely because the user education problem of cryptocurrency wallets and the various UI/UX issues it presents, but there's no mainstream apps that I can think of that actually try this.

Seems like it would work in dating apps, in advertising, in CRMs, in social networks of all types. Why hasn't it been done?

My guess is because we've only solved half of the problem with crypto. We have the cheap value exchange, but we don't have identity figured out quite yet.

robcohen··on Calypso: CalDAV/CardDAV server using Git to retain database history
Same here, I self host email with stalwart, and I use DecSync on syncthing for contacts, calendar is still on Google Cal. I'd love to hear what options exist.
robcohen··on Keynes Predicted We Would Be Working 15-Hour Weeks. Why Was He So Wrong? (2015)
As workers become more productive and earn higher wages in a given area, landowners can charge higher rents since workers must live within commuting distance of their jobs and land in desirable locations is inherently limited. The fixed supply of well-located land means that increased worker earnings create more competition for housing near job centers, allowing landowners to continually raise rents and capture much of the economic gains that would otherwise go to workers. This dynamic is especially pronounced in cities with strict zoning laws or other constraints on housing supply, as workers are forced to bid against each other for access to a relatively fixed stock of housing near employment centers.

Change the tax policy to one with a Georgist bent and this issue should be rectified.

robcohen··on Matrix 2.0 Is Here
Congratulations to the Matrix team. I look forward to trying out everything this release offers and seeing how I can implement in the organizations I work with.
robcohen··on Google Will Track Your Location 'Every 15 Minutes'–'Even with GPS Disabled'
I'm very confident this just isn't possible. If you want something with 4G/5G, you just cannot get open hardware. Without open hardware this is a moot point. There are a number of projects where you can use RISC-V hardware with 2G and even 3G open source hardware, but calling them equivalent in any way to an Android or iPhone is a... stretch.

I think the issue is the patents with the hardware needs to run out, but by then 6G or 7G will be out and you'll have the same problem. Anything with DMA that isn't closed source cannot be trusted. I'll die on that hill.

Even with projects like PinePhone, the best they can do is a privacy switch that turns off the modem. It's just not good enough to take it seriously.

robcohen··on Taking steps that drive resiliency and security for Windows customers
Microsoft being Microsoft. Of course they have to say they're going to do more. The reality is when you offer essentially infinite backwards compatibility, you attract companies that have zero desire to invest in their digital infrastructure and software.

Put another way, Microsoft seems happy to sell people the rope they use to inadvertently hang themselves with. Software is infrastructure, and safe and correctly maintained infrastructure is expensive. Corporations are externalizing machines, so we all bear the cost of poorly made software. Cybersecurity as an industry would be 90% smaller if software development wasn't "move fast and break things" and more "let's get this 100% right, formally verify what we can, test it for months and then release it."

Anyone who thinks Microsoft is anything but entirely complicit in making the world a significantly less secure place is either woefully ignorant or a fool.

robcohen··on Google URL Shortener links will no longer be available
From a security perspective, this is a good idea. People intuitively trust Google links. URL shorteners hide what you're clicking on. Sometimes even informed people click on links.
robcohen··on Talos: Secure, immutable, and minimal Linux OS for running Kubernetes
PXE seems like kind of a nightmare to manage. Seems better to just use Cloudinit or Ignition with proper Certificate management
robcohen··on Ranked choice is 'the hot reform' in democracy. Here's what you should know
According to FairVote, the organization behind RCV in the US, RCV is the only option that is resistant to strategic voting.

robcohen··on Bitwarden (the SDK and mobile app) is not FOSS
Come on. This is... disappointing.
robcohen··on AT&T says criminals stole phone records of 'nearly all' customers in data breach
I have to disagree. He is a fault. Ultimately, you are the only person who really should care about your own security. When you delegate that responsibility, you are still the one who made that choice.
robcohen··on Cities need more trees
For an opposing view, look at what happened during the freeze in Austin, Texas for an example of policies that allow for minimal tree pruning.

It was a significant issue that caused the city an incredible amount of damage. Electric was shut down for days, cars were destroyed, houses had trees fall on them, etc.

Might still be worth it, but an interesting data point nonetheless.

robcohen··on New Covid Shots Recommended for Americans 6 Months and Older This Fall
I think the issue is that most people don't have co-morbidities and most people aren't old. So when you're told to get the vaccine, and it turns out you're actually worse off due to potential heart complications, it feels like a betrayal. By the way, it is.

Part of this, I believe, was hedging bets in the fog of war that was a global pandemic. Part of it was just raw incompetence.

I am genuinely curious as someone who got every shot and booster. Do I actually benefit from this one? My understanding is the last one I did not statistically benefit from.

robcohen··on ID verification service for TikTok, Uber, X exposed driver licenses
Why is it absurd? I'm not following.
robcohen··on Show HN: I made an AI-finance tracker that let's you chat with your wallet
Didn't give it a test run for privacy issues, didn't see any effort to address that in the video but here's my take.

Drop the "chat 2 your wallet". Like why, why would I trust a company that replaces words with numbers.

Financial advisor costs " from $62,000" on what planet? How did you come up with this number? It sounds completely made up. No one hires a full time person outside of family offices. Totally ridiculous.

There doesn't seem to be a value proposition that makes any real sense in the video. It just says that your product is cheaper than a financial advisor and it would be useful. Show me how its useful.
