dzink··on US national debt reaches a record $37T, the Treasury Department reports
From his bio on wikipedia he was most successful betting against currencies at Soros but had little to no success with his own ventures.
dzink··on Show HN: Keeps – Mail a postcard that plays your voice
Until you get sold.
dzink··on Show HN: Keeps – Mail a postcard that plays your voice
The opportunity for abuse with a similar product is too big. Giving someone your voice and the address of your loved ones means they can potentially mock it with AI send anything any other time, including requests for money. The volume of abusers of seniors will only get bigger.
dzink··on Maintaining weight loss
Your brain needs protein and fat. Your brain tells your body when it is hungry and if the body doesn’t feed it, the brain is hangry. Protein satiates the brain and reduces cravings for less protein containing foods that the body will still eat in pursuit of satiating the brain.
dzink··on When we get Komooted
Public investors have an expectation of not losing their money. Thus public companies have to have either expectation of growth or strong cash flow to feed dividends. If a company has neither of those, Private Equity either turns it around or sells it for parts. They are the vultures of the business world. They buy the company with debt that its cash flows are supposed to pay back, and profit from the tax deduction on the debt and whatever is left in the end. A company is a machine where you put in 1 dollar and it comes back with more than 1. Employees get paid with steady reliable income called salary before investors do until the machine runs out. By law the board has to pay payroll if the employees are not compensated, or the board is personally liable for the salaries. They also have an inside view with how the company is doing better than any investor. They can and will bail when something goes funky. Any equity over is the perk of taking risk by investing in the company. The stress of wondering whether you will make payroll or have a business left after you have worked so hard to create and sweat so hard to work it is so deep that few would take it on - thus you have to give them proportionate carrot to look forward to or there would be no jobs.
dzink··on When we get Komooted
In the 80s the abuse was concentrated in the management layer of companies - executives would store cash and buy private jets and lavish properties for the “company” leadership to enjoy. Private equity trimmed that fat at the time.
dzink··on When we get Komooted
Any accumulation of power, especially government, becomes a target of corruption. Every single country and post has eventually proven that. The real innovation would be to prevent abuse of power systematically, and thus restore trust systematically. Anything else is just promises waiting to be broken.
dzink··on The append-and-review note
Because in a world where everything decays, including most physical objects and your health, your ideas preserved is the only thing that may remain of you in the end.
dzink··on The append-and-review note
After using Apple, and OneNote (which suddenly became unusable thanks to syncing becoming paid without warning) and others, I noticed in some cases the software was wiping the bottom of my large notes (or maybe not syncing them). Confirm indeed that the bottom of your increasingly large note is still there. Also need some method to backup or verify integrity of content added, because Microsoft wiping OneNote sync is one of many ways those services betray your memories and leave you empty handed.
dzink··on Countries across the world see food price shocks from climate extremes
Cherries, Apricots, and Peaches produced no fruit this year in the Balkans (and possibly elsewhere in Europe), due to an early winter warm followed by a frost that destroyed all blooms. That will likely impact a lot of european canning and food producers.
dzink··on The rise of AI as a threat to the S&P 500 [pdf]
Not if the lobbying budget of those making the AI money is larger than those that lose money to AI in the market.
dzink··on Show HN: I Built a Local-First AI Chat App with Advanced RAG
Why is there a subscription for higher end models? Can’t the user host locally and connect via API to whatever model they are subscribed to with the OpenAI or Anthropic or others?
dzink··on Manipulating trapped air bubbles in ice for message storage in cold regions
How did they come up with this idea?
dzink··on Finding Peter Putnam
The only truly scarce thing for living creatures is time. The HN crowd expects respect of that so a disclaimer would help filter people with the wrong expectations.
dzink··on Getting Started Strudel
I love this site! Great tool to make music and save music ideas and it’s low threshold fun way for people to get into code as well.
dzink··on Show HN: TrendFi – I built AI trading signals that self-optimize
The market is a battlefield of adversaries. For someone to cash out on a signal profitably, the others have to get less. A signal system is then easily abused by the signal maker who takes a position before hustling a bunch of people to take it. Or it is abused by a hedge fund or market maker who does the same and raises spreads on you when you are trying to make trades, etc.
dzink··on Strangers in the Middle of a City: The John and Jane Does of L.A. Medical Center
The hospitals usually bear the brunt of the costs and they are then distributed as higher costs to the paying patients.
dzink··on Endometriosis is an interesting disease
The major difference between private and public health care providers. Public providers are often burned out to a crisp and have little empathy or energy left. Private providers are compensated for each task and the incentive system and work ethic is dramatically different.
dzink··on Gurus of 90s Web Design: Zeldman, Siegel, Nielsen
They paved the way to the semantic web, which paved the way to Google extracting the data and building its own maps, shopping, and answers, and ratings and images and a bunch of other experiences on top of it and taking over traffic that would have gone to the web sites instead. Then AI scraped the same and now web traffic is becoming even less web. Flash made the web an experience - a place to visit and explore way before the metaverse. Web standards extracted the data. Now it’s pre-chewed and digested down to a AI answer.
dzink··on Flash Back: An “oral” history of Flash
Flash made it ridiculously easy to animate and export to the web. One tool and you could make an animated video, or an interactive app, or a game. There were fantastic competitive showcases of work, which made kids excited to learn and do it. It was low threshold multimedia and it on-boarded a lot of people into tech, including me. I worked on the Flash apps behind CNN and other Turner properties. The flipper tickers during the Obama election on CNN and Time inc, the Times Square billboard, all flash. My first visit to Silicon Valley was by invitation from Apple. Steve Jobs brought the developers from all major media sites (NY Times, Turner, ESPN, etc) to show us how to run non-flash video on safari. We had to redesign the video players on CNN and a dozen other big sites so jobs could demo the upcoming unveil of the iPad and have enough content to show without “ipad doesn’t support flash” boxes. That was beginning of the end.

The reality was that since Flash wasn’t indexable, search engines couldn’t index it but also you could pre-screen the content either. There could be really bad stuff hiding into easy to release apps. Plus if people could make cross-platform games on flash, why would they make them for app stores.

It was also too energy intensive and would have made battery life much smaller on iDevices.

dzink··on Ask HN: What are you working on? (May 2025)
Your email deliverability will be key to survival and easily damaged. All it takes is a couple of spam reports from good or bad actors and you can get black listed. Your users may forget they ever subscribed. Think of some work around to prevent that. Some examples - for large mailings you are required to add a physical address to your emails and an unsubscribe link. Those are filtered by mail providers and automatically sent to spam a lot.
dzink··on Ask HN: What are you working on? (May 2025)
I’m a mom. I built https://www.DreamList.com a few years ago because all of the wishlist companies were indexing your baby registry stuff by your name on Google. It has been growing steadily for years and it’s going well, so I never needed to raise money for it, but I noticed that a number of the Angel Investors in my network were former Traders. So I started looking into the market as well. A lot of even paid data sources were deliberately delayed - putting retail investors behind on any trade. I started digging for more reliable real time data, started generating my own candles from trades and doing my own indicators and doing my own trading and now that’s growing too. (not an outside thing, just for personal use). You wouldn’t believe the number of obstacles that get in the way if you want to do anything with finance or trading. Not touching crypto with a 10 ft pole - this is bread and butter stocks and you will still hit 100 gotchas. The more obstacles that show up, the thinner the air and the more money end up on the other side of overcoming each obstacle.
dzink··on It's Breathtaking How Fast AI Is Screwing Up the Education System
Grades are a competition with yourself. The grading curves where a certain % has to have a low grade even if they answer 90% of their test correctly. Curves means that if someone does close to as well as you they became an enemy instead of a future teammate.
dzink··on The Fall of Roam (2022)
Hi Baibhav, This was in August 2020. I have attached screenshots as a reply to Josh's reply above. It was early in the days so I could understand the founder perusing as a way of seeing how users are using the site, but not some random dude with a gmail. The logs were showing in my local storage on the browser. My notes were just test notes, so I didn't have anything important to worry about, but I never used Roam as a result.

You are in luck. I found a little video I took of the screen when it happened. It was from Aug 11 2020. Here is a screenshot with the log details: https://www.dropbox.com/scl/fi/g9jv8eh1ugi5qda0c6azx/0811202...
dzink··on It's Breathtaking How Fast AI Is Screwing Up the Education System
An easy way to circumvent the AI problem is to ask the kids to read the material ahead of time and use class time for socratic method questions each student has to answer to determine their grade over time. Social media is training the new generations to be fed information - mostly stuff that flushes down the brain with an emotion, but also content. AI can easily create custom courses fit to a child’s needs and add density or adjust pace without being tired. Have them answer questions along the way to adjust pace and you have an educational opportunity beyond measure. The real problem is not that - it’s the US system’s multi use as a credentialing signal. Grading on curves and having kids play zero sum games where there don’t need to be any is what makes bad behavior unethical and unethical behavior a habit at an early age. With AI everyone can have mentors in every discipline (some better that others). So instead of encouraging laziness with laziness, invest in gamifying the degree experience so the more levels a student unlocks the more advanced they are certified to be. You will find abundant qualified people in no time. The real problem is that the current qualified people don’t want abundant competition for high paying jobs.
dzink··on The Fall of Roam (2022)
It happened several years ago - when Conor was holding talks on Clubhouse. I had created an account with a few test notes and went back days later. The notes were not listed or linked anywhere. The person’s email or name was showing in the log but he was not even outed as an employee on linkedin at the time - so I originally thought someone has hacked my account or was accidentally given access to my notes. Then I asked the founder or the person and they said it was a new employee. I have screenshots somewhere but I don’t remember how i reached out to them - if it was a service chat, or email, or twitter, or clubhouse. I always check the network chatter on new sites I use - very enlightening about what they think of customers. A lot of times you see flags for things they want you or don’t want you to be, or what they want to upsell to you. Reactive sites put all kinds of logic in the front end where it doesn’t belong.
dzink··on The Fall of Roam (2022)
I started using Roam and as a proper geek, dug through the data it sends back and forth about me and my notes in the browser console. It was doing access logs and some random day I saw some random dude’s name in the access log for my notes. I reached out to ask. They told me he was a new employee. I saw no reason to save personal notes and ideas on a platform where any employee can enjoy them. Thereafter I took my notes to tools i wrote myself. Very enlightening to the incentives for building such tools.
dzink··on How three years at McKinsey shaped my second startup
The engineer in me immediately looks for ways to map out how tax avoidance via crypto trading on life insurance funds via a Bermuda company can possibly go wrong. Insurance has a nice long term cash flow that has proved very sweet for Berkshire Hathaway, and investment on top of that gets perks for the insurance. However Crypto, which has liquidity issues and is heavily scammed/stolen would benefit far more than the users of business. The holdings would stay for decades, allowing arbitrage of the main company with user investments. If there is a leak or a collapse of the crypto, the customers won’t know it until they can’t get their funds back, but since AI is handling the claims, they may never even find out the real reason they can’t get their money back. And since it’s life insurance, the buyer might never find out, while their descendants or loved ones may not know how to deal with it or be plenty confused by the lack of customer service. Very novel scheme.
