Hey HN, I built aireelgenerator.com, after seeing a couple of similar apps online. I wanted to learn how to use video generation libraries, so I built this. It is an app that fully automates the creation of faceless videos. Simply choose a topic, and it will generate and upload new videos to your Youtube, TikTok, Instagram, or Facebook account every day. Ideally, I'd like to keep adding features including an editing timeline, etc.

Would love to hear your thoughts and feedback


agreed. also, I think it will have the secondary effect of users rewarding non-ai content, and discourage ai generated content makers.


the chicken definitely came first!


Do you think there could be other titles that might be better suited to this work?


"Yet another partial introduction to some things in data science from an impractically mathematical perspective"


Can you elaborate on what kind of circular dependencies are you referring to and how would catamorphisms with `Either CycleDetected a` help to reduce those dependencies?


Okay, imagine you've got a list of securities and their underlyers. You've got a flat file that represents this information. You try to represent it as

Security Underlying Security (Security)

Where that's the Security object, not the Security ID.

This works great for moeb, until the day that someone accidentally introduces a cycle. Instead you want a representation that looks like:

Security Either CycleDetected a

You can call traverse to make that `Either CycleDetected Security a`.

Is that making any sense at all?

You rapidly realize that X knows Y and Y knows X.


Can you do that without losing all the fun of the magic one-liner with Haskell's inbuilt graph reduction? Otherwise, you may as well use Python ;-)


You gain all the fun of Fix, though.


Can you detect cycles in general though? At first blush it feels like a halting problem.


You can't detect all possible cycles statically, but you can definitely detect them when they happen at runtime. When calculating a value, track its dynamic dependencies. If it ends up depending on itself, you have a cycle.


That's great news that your cholesterol and triglycerides were high and that everything else looks normal! Are there any other tips that you would suggest for making lifestyle changes to help lower cholesterol and triglycerides?


I’m not a Physician or Dietitian, but my dad is a Gastroenterologist and my wife is a Registered Dietitian, so some of their knowledge rubs off on me. And my PCP gave me some tips last week that are still fresh in my mind.

- Exercise can help lower cholesterol slightly. But try to have a reasonable balance between cardio and resistance training. Too much cardio risks having some muscles actually weaken if you maintain a large calorie deficit.

- Diet-wise, you want to go for sustainable weight management, so no extreme or gimmicky diets. Avoid Atkins and Keto (unless a professional tells you you actually need to avoid carbs), extreme fasting, etc.

- 3 moderate meals a day are better than 2 or 1 large feast(s) because they keep your metabolism going for most of the day. Your body can adapt to feast/famine and can go into ketosis, but these are survival mechanisms and harmful, even counterproductive, if you keep your body in these modes for long periods of time (you might even gain weight in feast/famine mode because when you do eat, your body converts as much sugar into fat as it possibly can, in order to prepare reserves for the next “famine”).

- Some fasting is good for spirituality and to teach self-control, but it should not be a permanent state (I plan to fast Mondays and Thursdays as much as possible, leading up to Ramadan in about 50 days). Fasting every single day for the rest of your life is not realistic and probably does more harm than good.

- Eat raw nuts (raw almonds have been observed to lower total cholesterol, lower LDL, and raise the HDL/LDL ratio) as much as you can within your calorie allowance. In general, more plant-based protein and fats, and less animal-based is very helpful (but watch out for high saturated fat from coconuts, and too much soy can mess up men’s hormones). Edit: the soy evidence is not conclusive - see comments below.

- Keep your calorie allowance reasonable and sustainable, and try to eat a good variety of fruits, vegetables, grains, beans, legume, meats, etc. with moderation in everything.


I'm going to ask for a reference on the soy comment. I know there's a lot of fear mongering on soy but I haven't heard of any studies to prove that.

Rest of the advice seems good. Lower fat in diet (specifically dairy fats), increase exercise, higher fiber, lower sugar, more nuts/avocados/salmon.

Treat the disease and not the numbers - so look at all your risk factors for atherosclerosis.


I’m not suggesting avoiding soy altogether, just cautioning against excessive consumption of it. Studies are showing mixed conclusions, but it’s not all fear mongering:

Study showing some effect: https://pubmed.ncbi.nlm.nih.gov/15735098/

Study showing little effect: https://pubmed.ncbi.nlm.nih.gov/11880595/

While the evidence is inconclusive, I wouldn’t take chances if I were trying to have kids. I would imagine getting __all__ of your protein from soy could potentially be harmful, perhaps even in ways other than decreasing testosterone and sperm count.

In general, everything in moderation is best.


> Fasting every single day for the rest of your life is not realistic and probably does more harm than good.

What evidence is there for this statement? What is considered "fasting?" I can't see how a 12-hour feeding window would be problematic. I could understand some people might develop "disordered eating" if their approach is unsustainable, but "more harm than good" isn't true for those that can do it.

One reason for fasting is that it improves insulin sensitivity.

From: https://www.health.harvard.edu/blog/intermittent-fasting-sur...

"Based on this, researchers from the University of Alabama conducted a study with a small group of obese men with prediabetes. They compared a form of intermittent fasting called "early time-restricted feeding," where all meals were fit into an early eight-hour period of the day (7 am to 3 pm), or spread out over 12 hours (between 7 am and 7 pm). Both groups maintained their weight (did not gain or lose) but after five weeks, the eight-hours group had dramatically lower insulin levels and significantly improved insulin sensitivity, as well as significantly lower blood pressure. The best part? The eight-hours group also had significantly decreased appetite. They weren’t starving."


I can’t edit my original comment but I’ll try to add some nuance:

- When I say “fasting” I mean not eating for a good chunk of the day. My Muslim background made me overlook the need to define that clearly.

- I doubt most people can sustain fasting indefinitely, so “disordered eating” and metabolism going out of whack is the most likely outcome.

- If someone has a good reason to fast indefinitely - based on professional advice - then they should go for it. But, like other extreme measures, it’s probably not for the general population.


High cholesterol runs in the family (my grandfather exercises 7 days a week, is thin as a rail, and had a heart attack at 60). I'm 31 and learned that I have high LDL two years ago.

I can only speak to my case, so YMMV. Through a liver blood panel, I learned that I had high bilirubin, SHBG, and GGH - which indicate compromised gallbladder and liver function. One doctor suggested I have my gallbladder removed.

Instead, through research on pubmed and examine.com, I was pointed to TUDCA - a bile salt that helps clear cholesterol and biliary sludge. After two months of supplementation, I've seen a severe reduction in intestinal discomfort - and I suspect a follow-up blood test will show a reduction in my high liver panel and LDL.

If you have abnormally high LDL for your body type and lifestyle, I would encourage you to get a liver panel and look into TUDCA.


Wow, that sounds great! What led you to make these changes to the Signal Android app? How can others join you in these efforts?


Seems like they wrote exactly why?

> Sometime leading up to October of 2022, the folks at the Signal foundation lost the plot. Signal has since dropped support for SMS, and is inexplicably adding "stories" to their personal messaging app. I despise this.

> Instead of just complaining about it, I decided to do something about it.

True hackers :) Thank you


Good question! Do you have a personal strategy for deciding which task to prioritize, if any?


It is a very complex function which takes into account all your previous experiences, your value system and your estimations regarding the future.

Good news though! Your brain already computed it, and presents you the answer in the form of "I want to do that thing right now".

Quick debug sheet:

- my brain in wrong, what I want is not what I should - are you sure? Figure out your narration. If you ever have been excited about some project you know how well your "want" will align with your "should". You may be stuck in some story about yourself which you haven't updated.

- I want it all! Yeah you are really still just looking, if you are not sure what you want, that's not really a problem. It's fine to not want anything in particular. If you keep telling yourself you really want it all just choose at random, and then when you "have time" slowly and patiently explain yourself that your time is finite, and amount of ideas you can come up with, not necessarily.

I suggest also trusting yourself with this. Worst case scenario you spend some time doing the thing you wanted to do and observing that will be a valuable data point (automatically integrated) into your future "I want to".

edit: I answered it in the context of personal lists, startups have much simpler optimization function


That's really interesting.
