useful··on Empty storefronts are killing neighbourhoods
My understand is that commercial real estate loans require additional collateral for lower rents than what was agreed to when the mortgage was created. Building value is basically (monthly rent * constant).Accepting lower than when the mortgage was written will trigger provisions that value the property differently and require the building owner to add principal to get back to 25%.

If lowering the rent by 10k a year lowers the value of the building by 100k, the building owner may have to add 25k that they don't have to keep the building from falling into default. If you have a completely empty building and you accept a lower rent in one of ten units, you could need to put down 250k it of you have many building under one loan they may want millions because of how it changes the loan valuations.

useful··on Some Vaccinated People Are Dying of Covid-19. Why Scientists Aren’t Surprised
Serology tests are a thing for a lot of vaccines. You can get them from a doctor if you are traveling overseas to see if you need redo a vaccine.

I'm not a doctor, but if you don't have any kind of immune response after 2 doses of pfizer/moderna. I'd strongly suggest that you ask about a serology/antibody test especially if you are older or have health conditions.

useful··on Taxes Are for the Little People
Thats not the same thing. Imagine there is a 3rd person whos whole job will tell you that they "know" when to sell the restaurant. For this, they will charge a 1%/year flat fee based on the current value of the business. They'd average 15k/yearly for 10 years. They also charge carried interest on your paper gains, so 10% performance on your 100k/year average gain, another 10k/year.

They are effectively making a salary for labor but only paying 0-20% on 25k/year from our business depending on how many other clients they have. This is much lower than the 10-37% most workers pay on their labor.

I'd argue that the business sale is capital gains. I never said it wasn't in my original post.

Carried interest and a fixed flat fee to manage an investment (which most people call a salary) should not be taxed as if they are capital gains.

useful··on Taxes Are for the Little People
Why is carried interest still a thing? Why are fixed fees taken by investment managers not taxed as income?

I think the current administration could fix these things easily but we are talking about all kinds of other things while ignoring low hanging fruit.

useful··on Try APL
various interpreters have ways to make external calls via com/web/etc. APL is basically python calling C++/C#/Java/etc.

Seeing pure APL for XML parsing is.. interesting. Most interpreters support saved/read of functions in a more procedural way.

useful··on Try APL
As someone who has used APL professionally to maintain a legacy codebase https://en.wikipedia.org/wiki/Write-only_language

Anyway, I like reduce, shape, membership, find, and/or, and ceiling/floor. I actually like dealing with arrays in this way.

IMO, that is why numpy/matlab is so much better than APL.

useful··on Ethereum will use around 99.95% less energy post merge
I'd much rather put kwh limits on proof of work. That would stop large farms that aren't green.

Outside of ethereum, proof of stake is no different than a database. The ownership is so centralized that you only have 3-5 people/organizations approving everything.

The whole point of crypto was to be decentralized, proof of stake is not that. Cardano, solana, they all are pointless as a token because the whole supply is largely owned by a few people.

useful··on How this Ends
the risk in being in cash is much greater than anywhere else

Technology is deflationary, growth in tech looks to be the least risky. Technology has prevented inflation and will for a while. I think the only lever the US has for inflation is largely in housing as it makes up something like 50% of the CPI.

Fixed assets are very inflated but I would like to think the commercial market will take a hit before the residential market. Some factories, plants, and office space is worthless in a world with zoom, solar, and electric cars.

Buy a house, money is cheap. At least you'll have a roof over your head and it will be easier to pay off the loan if there is any kind of inflation that the government has said they want.

I bet this uses DLSS to get the resolution. I see no one talking about it but why push a high bitrate when you can just upscale with AI.
useful··on Launch HN: Aviron (YC W21) – High-Intensity Peloton for Rowing
Once you get the "feel" doing wattage is pretty easy on a static trainer if you change gears or your pedal stroke rate. That amount of practice and effort to learn when you only want to spend 10-20 minutes working out is beyond a beginner. Aviron's whole website is built around games and varied resistance. Having the rower do all the thinking for the user ala zwift workouts on a tacx is attractive.

I don't understand why pelotons are popular when a tacx/wahoo/etc are lightyears ahead in feel and blunting the peaks of "pain" from beginner mistakes. The more advanced ERGs that adjust are super forgiving and the same would be for rowing, avoiding pulling too much lbf and having your arms hurt for weeks = avoiding the workouts.

People doing HIIT cardio usually blow up if they put out 10% more wattage for a minute or two than their FTP. If a machine makes it so you can workout "forever" and simplifies the interface of games/workouts so users only need to focus on a single metric for game while adjusting all the others, it would be a killer feature.

useful··on Launch HN: Aviron (YC W21) – High-Intensity Peloton for Rowing
I have a C2 and a Wahoo Kickr.

I think you are targeting the wrong market if you intend to build a machine.

As a cyclist, the market sweet spot to me is the ability to set a wattage on a rower and have the machine automatically adjust the resistance so that I can hit the correct wattage/hour.

On the bike, holding a steady cadence and having the machine adjust the resistance so I can hit whatever % of FTP I'm wanting is the killer feature the C2 is missing.

All the other comments referencing injuries/etc are reflective of the need to make an ERG that allows you to just say "do 25 strokes/min" and if you blow up or cant hold the pace, drop the target wattage. It's harder to hurt yourself if the machine is setting the difficulty based on your pace and putting some sane max limits in.

useful··on How Silicon Valley destroyed Parler
Counterpoint: if tanks were the primary way to transport something obvious like a giant battle tank that were being used to kill people and attempt overthrow of the government. If the checkpoints setup couldn't catch enough of them to remove the danger, would you support shutdowns of the highway infrastructure until the checkpoints could stop them?
useful··on 'Big Short' investor predicts Tesla stock will collapse like the housing bubble
I have no idea. But you can also sell an aftermarket 10k upgrade of "trim". I don't think toyota can offer that.

I don't think the bull case is very strong. But I do think the previous bear cases of "they cant run a factory", "they cant scale production", etc are all mostly disproven.

I would describe myself as bearish on their self-driving future as something I could trust to sleep or do work in. The recent videos are impressive and exciting. I hope they succeed.

useful··on 'Big Short' investor predicts Tesla stock will collapse like the housing bubble
because they can sell 10k of software upgrades?

Tesla is worth like 700/share in 4 years if everything works out with their factories and expansion. If they hit the lottery and magically figure out self driving, then they will 2x-3x, because they can have better than software company margins.

I don't fault the crowd for thinking they will have self driving cars in a few years. I don't see it really happening outside of a few really well managed cities.

useful··on Playing on Hard Mode
I love the concept of uber and yelp, I've used them a lot. But once I could price compare them via google maps they became un-investable to me because they can only compete in 2 areas, people and policy.

Once you lose control of the sales channel your business is commoditized and pricing pressure will remove all margin. Competing on price is a losers game if you want margin and growth. You can make a niche by having a better experience or better refund policies but the value competitor will drive the price down and steal marketshare.

Airlines and hotels are perfect examples, now ridesharing is little different.

If Airbnb can continue to control the experience then I think it is a great company to invest in. But if you can buy an airbnb on expedia and see the prices of nearby short term rentals from other competitors like vrbo then they are toast.

Aggregators are easy-mode tech, you are transferring wealth by taxing margin of other companies that have operational efficiencies or deficiencies.

useful··on The Era of Visual Studio Code
All of this is fine if you don't work with others. The point of these tools is to standardize around something to reduce the cognitive load someone has to experience contributing to code that they didn't write. The amount of possible paths are commonly reduced for the reader.

Linting, snippets, autocomplete, are all things that prevent you from bending the nail or breaking off the head which makes maintenance harder for the person who has to find the nail and remove the nail. If I don't have to redo the nail, the cost of the nail and my time are also saved.

useful··on The FBI is secretly using Sabre as a global travel surveillance tool
The industry is moving to a being able to purchase products instead of complete PSS/GDS solutions. As an airline you'll be able to buy an inventory management system from Amadeus, a pricing system from Sabre, a support system from TravelSky, and a website from Travelport.

The best example I can think of is American. They have Amadeus running their international website. Their ticketing system is internal. And all their inventory is managed in Sabre.

Southwest was similar, for a while Amadeus ran their international site while Southwest ran an outdated internal system for domestic travel that didnt support flights leaving and arriving on different days. They eventually had Amadeus move into running their domestic stuff a few years ago and now they have red-eyes.

Delta runs all their own stuff on a mainframe and from the outside it looked like a slow moving disaster. I know Amadeus sees all their inventory and looks at each passenger.

useful··on My dad got scammed for $3k worth of gift cards
I have no personal experience but my waiter and restaurant owner friends seem to think that gift cards are also a good way to skim some money from your employer while traveling. Buy some bread and peanut butter at the store, get a gift card and a drink at a restaurant. Or if your per diem is big enough, go all out and get a meal and a gift card.

useful··on IBM will offer free COBOL training
I was the team lead to rewrite a large APL codebase with a very small team as part of a much larger group that refused to change and I'll agree with this. Once we started documenting and building tests for the code that replaced APL it became clear that the complicated bits were easy to replace and the hard part was just man hours converting all the conditional logic.
useful··on Autocomplete as an Interface (2015)
Autocomplete is the first step. Then you get linting, static analysis, autoformat on save, and code snippets. All built into your fancy IDE with plugins. You are super productive, you learn from its suggestions that you can quickly flip through, and your coworkers are happy that they only have to check your code for correctness and implementation, not style and edge cases.

but it was used in many places, so the rule of three applies.
