jraby3··on He set out to walk around the world. After 27 years, his quest is nearly over
I rode a bicycle from Canada to Mexico (in about a month) with a close friend. We bought a book called Bicycling the Pacific Coast (before smart phones).

I had a cheap $150 univega bike and my friend had a $3000 cannondale. His broke mine didn't :)

We were amateurs. We hitchhiked to a bike shop near San Francisco to fix it. Had some saddle bags with our tent and sleeping bag, clothes and water.

It's very doable. Hardest part is just showing up.

jraby3··on What you can get for the price of a Netflix subscription
YouTube does a really good job at making playlists on the fly. Choosing the first song on YouTube will get you a playlist of somewhat similar songs. It took me a while to get used to relative to Spotify but now I much prefer the YT method.
jraby3··on What you can get for the price of a Netflix subscription
Other than watching shows in a foreign language and reading subtitles, is there any specific way you use it to learn a foreign language?

I am learning Hebrew but I find that many Hebrew Netflix shows do not offer English subtitles. It's really frustrating.

jraby3··on What you can get for the price of a Netflix subscription
YouTube music is really good. I prefer it more than Spotify and if you already pay for YouTube it's free for you.
jraby3··on Meta buried 'causal' evidence of social media harm, US court filings allege
I don't think any of those items have had the significance and decisiveness of social media, or have been controlled by billionaires who have corrupted the election systems.

Social media seems far more dangerous and harder to control because of the power it grants its "friends". It'll be much harder to moderate than anything else you mentioned.

jraby3··on SEC approves Texas Stock Exchange, first new US integrated exchange in decades
As someone who's considered taking my company public (not a tech company) it's nice to see easier listing requirements on this exchange than the big ones.
jraby3··on When Bruce Lee trained with Kareem Abdul-Jabbar
Josh waitzkin breaks this down really well in his book the art of learning.

He's a chess champion and push hands champion and discusses how to learn. Basically as you become and expert in something you learn to pay less attention to the surrounding environment and only focus on what matters, which allows you to see it in "slow motion". This applies to chess champions where masters eye movement focuses on a much smaller part of the board than a beginner, and also in push hands or BJJ where experts fighting for a tiny bit of grip change is what matters but a novice might just see the whole body not moving or doing anything that matters.

Very worthwhile read.

jraby3··on ChatGPT Pulse
It suggested a significant increase in fiber which I wasn't really paying attention to, based on numerous studies showing it would have a positive impact on my ldl and non HDL cholesterol (my triglycerides and HDL good cholesterol are very good).

It also suggested eating more fatty fish like salmon 3x per week. And substituting good fats for saturated fat, which is obvious but still very motivating.

jraby3··on ChatGPT Pulse
The benefit outweighs the lack of privacy.

I just uploaded recent blood tests and other health info into ChatGPT and then had it analyze what I could do to improve my health, specifically cholesterol and sugar. Then asked it to red team its advice and provide me with one or two things that would generate 80% of the results.

It's pretty awesome having a private doctor that's read every study out there and then can generate advice that will make me live longer and healthier. My doctor certainly doesn't do that. As long as I'm in normal range he doesn't say anything.

jraby3··on America's top companies keep talking about AI – but can't explain the upsides
As a small business owner in a non tech business (60 employees, $40M revenue), AI is definitely worth $20/month but not as I anticipated.

I thought we'd use it to reduce our graphics department but instead we've begun outsourcing designers to Colombia.

What I actually use it for is to save time and legal costs. For example a client in bankruptcy owes us $20k. Not worth hiring an attorney to walk us through bankruptcy filings. But can easily ask ChatGPT to summarize legal notices and advise us what to do next as a creditor.

jraby3··on The health benefits of sunlight may outweigh the risk of skin cancer
I don't think it's at all healthy to look directly at the sun.

But I have noticed that my eyes get weaker after spending a lot of time indoors, like if I'm sick. Getting enough time in sunlight seems to be heavily correlated with better eyesight, both in my personal experience fighting farsightedness as a man in his 50s and with studies done on children regarding nearsightedness.

jraby3··on Repetitive negative thinking associated with cognitive decline in older adults
At least in business, this isn't really true. It makes more sense to form long term partnerships by being trustworthy than to have a reputation of hostility and lawsuits.
jraby3··on Airbus A320 Poised to Overtake Boeing 737 as Most-Delivered Commercial Airliner
Pricing on these planes is pretty complex. It's a stretch to say that airbus is unequivocally more expensive without comparing various options.

Source: my brother worked for Boeing in sales and has been in the industry 30 years.

jraby3··on I tried every todo app and ended up with a .txt file
Don't use a ToDo list. Just put stuff on your calendar!
jraby3··on ‘I witnessed war crimes’ in Gaza – former worker at GHF aid site [video]
Link to show hundreds of thousands of detainees in Israel?

That seems like a massive exaggeration.

jraby3··on Do not download the app, use the website
I feel like this didn't touch on the second most important reason not to download the app.

Most of us over use (or are addicted to) our phones and especially to social media. Every barrier you can put in you way to prevent opening it is an improvement.

Opening safari and then having to type in the site name is a better barrier than just opening an app. Logging out every time is a barrier. Putting timers on websites through screen time is a barrier. All these tools help us fight against tech controlling us instead of us controlling the tech.

jraby3··on How YouTube won the battle for TV viewers
It makes around $40 billion a year in revenue. I find it hard to believe it operates at a loss.

It's not a monopoly. Tons of other sites successfully host and profit from videos, such as TikTok facebook etc.

jraby3··on How YouTube won the battle for TV viewers
Hosting costs are only going down. Now with nuclear energy costs will continue dropping as well. Google doesn't break out costs but their last earnings report yesterday had YouTube revenue at $9.79 billion for the quarter. I find it hard to believe that it's not profitable.
jraby3··on Officials concede they don't know the fate of Iran's uranium stockpile
I personally think that it's not ok that Iran has sewed so much discord in the Middle East by arming Hez, Hamas and the Houthis.

I'm very happy the US got involved and destroyed their enrichment sites. I'm also happy Israel didn't wait around for Iran to destroy them, which they've actively been trying to do in this war.

jraby3··on Officials concede they don't know the fate of Iran's uranium stockpile
I really thought Iran was breaking the deal too. Just did a google search and found articles from politico and AP fact checking and it seemed that Iran was complying with the deal.

Do you have any links or relevant sources to show that they weren't?

jraby3··on U.S. bombs Iranian nuclear sites
No way is KSA helping Iran.
jraby3··on U.S. bombs Iranian nuclear sites
The PA still uses a pay to slay program encouraging the murder of Israeli civilians within the 67 borders.

President Abbas has a PhD in holocaust denial.

Calling the PA left wing isn't accurate. It's also bent on the destruction of Israel and the Jewish people.

jraby3··on U.S. bombs Iranian nuclear sites
They have repeatedly threatened Israel and the US. Nothing good (for western democracies) comes from Iran getting a bomb.
jraby3··on WhatsApp introduces ads in its app
WhatsApp has long promoted itself as a safe alternative to apps like Telegram and Google’s Android messaging. Users flocked to the app globally, finding it a cheap and secure alternative to texting, particularly people in unstable political climates and authoritarian countries, since its messages cannot be easily intercepted without access to personal devices.

jraby3··on A Texan who built an empire of ecstasy
I take it once a year with a community of about 150 like minded friends at my house in Vermont. It's amazing.

Find your tribe. It does exist.

jraby3··on Ask HN: What are you working on? (April 2025)
What are some examples? I'd love to check out your store but I'm worried by the time you launch this post and any communication with you will have vanished to the ether.
jraby3··on A unique sound alleviates motion sickness
To save a click:

"The brown note (sometimes brown tone or frequency) is a hypothetical infrasonic frequency capable of causing fecal incontinence by creating acoustic resonance in the human bowel. Considered an urban myth, the name is a metonym for the common color of human faeces. Attempts to demonstrate the existence of a "brown note" using sound waves transmitted through the air have failed. Frequencies supposedly involved are between 5 and 9 Hz, which are below the lower frequency limit of human hearing. High-power sound waves below 20 Hz are felt in the body."

jraby3··on US Government threatens Harvard with foreign student ban
It's perfectly fine to criticize the government of any country. But is anyone in the UK, or Syria, or Iraq (my birthplace) saying those countries don't have a right to exist? Why just Israel?

When you have a standard that exists for one country or people that doesn't exist for anyone else, isn't that the definition of bigotry in all its forms?

jraby3··on US Government threatens Harvard with foreign student ban
It was referenced in the Wikipedia article I linked to. Did you read the article?
