Ask HN: What is your take on Bryan Johnson's "Blueprint"?
I have recently taken a somewhat keen interest in longevity research, and Bryan Johnson has sort of become the mascot of that movement so to speak. His research mostly focuses on slowing down his rate of aging by optimizing all major functions of his body, his whole life basically revolves around this one goal which is unrealistic for most people.

I have thought about doing a version of what he does, I just don’t really know if his research is trustworthy. That’s beside the fact that he has a full suite of medical testing equipment and the staff to use them — this is how he gathers data about what’s working about his protocol and makes adjustments accordingly. If you don’t know, his protocol involves a pretty strict vegetarian diet, taking 100+ supplements daily, and more bizarre stuff like giving himself plasma extracted from his son. He also does the obvious stuff like exercise, no alcohol, etc.

What do you all think?

It's still a bit more interesting to read "I got my devices stolen by the state" than 100th repetition of "Giggle blocked my account and I don't bother having backups" which is allowed here ad nauseam.
I just skimmed it, but it looks like vim really has undo/redo "solved":

- Modal editing makes for nice "undo" points, clarifying whether undo should undo "World!" or "!".
- "g-" and "g+" eliminate the "orphaned redo". They walk the entire undo/redo tree rather than just the linear undo/redo.
- Time travel undo/redo is really handy when you want to go to where you were on the wall-clock. ":earlier 15 minutes" takes you to the code as it was 15 minutes ago.
Short term individual and small group behavior in artificial conditions can be somewhat reliably measured. How well and to what situations these genralize to is a harder question.

Larger groups and timescales are (in practice) outside the domain of science (in the most rigorous form) and must be studied with other methods and epistemological criteria. This also leads to major abuse of statistics as the inference has to be done with unrealistic assumptions and unwieldly models.

The "brand" of science is so strong that many fields, especially economics, want to appropriate it even though they don't and can't do science in the strict definition.
You’re partly right. If anyone signs up at all, then it’s a net gain in ‘conversions’. But it’s not a majority at scale, and it doesn’t have to be anywhere close in order to work. Typically only a small minority of visitors convert to being email subscribers, and then only a small minority of those email subscribers convert into paying customers. It’s not uncommon for the paying customers at the bottom of the funnel to be in the single-digit percent of visitors, or less, and the people annoyed by popups who leave to be the overwhelming majority.

How would you create the Encyclopædia Britannica locally? Who would invest the massive amount of money required to make an encyclopedia, especially one like that, without expecting a return?

That's not to say that no copyright means no way to fund big projects, you just have to collect those funds up front or rely on generosity - both of which are less likely to succeed because copyright makes the result into something you "own" rather than society and people are less inclined to fund your own private enrichment.

I haven't had a paid Times new-related subscription for years, but still get the email newsletter and it is quite useful. The cover a pretty wide variety of topics [1] so most people will probably find many of the mailings uninteresting but enough cover things that are common recurring topics of discussion here that most will probably find a few useful. Just filter it to a separate mailbox and check now in then--the subject lines of the mailings are usually accurate enough that you can tell at a glance if a particular day covers something you are interested in.

This is interesting to me. My experience was the opposite. So much time in my honors math in high school was focused on proofs and deriving them, that developing and intuitive understanding of the material and how to apply the math to solve problems was secondary.

Every time you touch anything ML-related you need it. Data scientists not only love their Python but also don't usually use libraries that have JVM bindings. I have not noticed much improvement in this area since 2018 and for some reason djl.ai is not popular in the wild.

Other than that, I can think of only really niche use cases (e.g. calling ffmpeg, query engines using the C++ Arrow implementation, likely something trading-related).

I had both a Pebble v1 and a Pebble v2 and loved them both. Pebble went defunct though, so I switched back to a Seiko 5 automatic dive watch once I found I didn't really care for any of the other available smart watches at the time.

There's something beautiful to me about a mechanical watch being tied to my personal relativity. Compared to an NTP synchronized smart watch, nothing should update the time on my watch but me. The actual usefulness of this feature is merely philosophical but it makes me happy to consider.

The only thing I miss is weather at a glance on my Pebble. I used a watch face with the temperature on it and to this day I still look at my wrist when I'm thinking about the temperature lol
> However, you have to escape and sanitize output explicitly, which is not a thing in pretty much any modern templating language.

Idk if it has to with "modern" or not. Proper escaping contexts (whether, and which delimiters to quote in attributes, in content, in markup declarations, ...) are already defined by SGML, with HTML-aware templating or other vocabulary-specific expansion such as suppressing <script> elements injection as would be required by basic user commenting also being covered by SGML. My impression was that go/templating (and maybe pug?), while considered advanced relative to other templating packages shitting strings into markup, still requires explicit sanitation depending on the insertion context.

You keep bringing up the broader Futurist movement, but I am discussing mostly one specific Futurist founder who was also an early member of the Italian Fascist party and lifelong supporter of Mussolini, and whom Andreesen quotes and considers a "saint" in his newest manifesto. Even though the broader movement was more complex and politically diverse, Andreesen is specifically praising the fascist, not the movement (without even something like "even though he later became a fascist, in the beginning [...]").

Also, while I don't think Ayn Rand saw it that way, I think it's pretty clear that her objectivism has the same Great Men ideology as much of fascist thought, and the same disdain for democracy, religion, and the needs of the people. It's true that objectivism is more individualistic while fascism is more collectivist, but they amount to the same observation in the end: the Great Men naturally rule over the unwashed masses.

>One test. A really truly automated test, with setup & invocation & assertions (protip: trying working backwards from the assertions some time). It’s in the writing of this test that you’ll begin making design decisions, but they are primarily interface decisions. Some implementation decisions may leak through, but you’ll get better at avoiding this over time.

If you're truly doing interface decisions without leaking implementation decisions then your test is probably doing something like using playwright to follow a user story or calling a REST API and seeing what comes back.

In which case, it probably isn't providing software design feedback, as described in the previous blog post: https://tidyfirst.substack.com/p/tdd-isnt-design

If you can afford to optimise for your "Recall rate" over your "Precision" as such(e.g. your current time or number of opportunities/ideas is high), then go one step further than the Mom test and what people here say:

You need to listen to the diversity of what people think your solution will do and enable and you want a clear plural answer. If your problem is "urgent" and the solution is "obvious" the way people think it will work is too segmented, you can still have something that fails on unit economics because too many people have their expectations broken. (Learnt this from Jason Cohen). Really you need to talk to at least 10-20 people and try different questions, different approaches. Some ask about the problem. Some review paper designs with. Some, ask them to sit down and show you how they do the task. Generally very few ideas will be both an urgent problem people would pay for that people ALSO think will work and output in a fairly uniform way amongst the stakeholders.

The two are interchangeable; a computer can make one from the other. Storing deltas makes common operations slower, as getting file contents requires replaying all the deltas through history.
I think they first need to shed a few more people from the generations that saw the Troubles, so that old grudges stop being relevant and it becomes more of an administrative issue than a religious/sectarian one.

What's a voluntary prison sentence?
We can get into the weeds about the details, but what I'm talking about is mostly that in Python (and in most languages really, AFAIK Ruby, Java, or C# are the same to list just a few) objects have to return the hash itself, so the hash function is fixed by the type.

In Rust, the Hash trait is only used to feed data to a hasher such that the type can decide what should be hashed. The creation of the hasher is done by the collection, and thus provides better opportunities / flexibility in customising the hash function.

WordPress sucks if you're writing a custom theme or plugin. Their codebase is old and it follows outdated standards (e.g.: they use array() instead of []... in 2023, really?).

But, if you're using WordPress to publish a simple website, I think the most recent versions are great. The new Guntenberg full site editor is easy to use and it lets you customize your entire website easily, without the need to rely on custom code or, even worse, custom page builders.

Some people that replied to this comment were saying Damascus steel was "lost", which is mostly a meme.

If we're talking about modern times, Damascus steel can be easily forged and replicated by modern hobbyist smiths.

If we're talking about being lost at some point between 0AD and, say...1900 AD, then it was probably just not economically viable to make it. Damascus steel is very labor-intensive to produce and does not offer significant structural advantages compared to regular mild or tempered steel. Certainly not in applications where most metal was used in the middle ages (hint: it was warfare).

For example, it makes no sense to make a full-plate armor or a musket out of Damascus steel. It would be mostly a status item, rather than a practical tool.

Hence when we say "lost", it likely just means people looked at it and decided it wasn't worth the time outside of niche applications. And since it was niche, there is very few historical artifacts, that make it look "lost", when in reality, there just weren't too many of these items to begin with.

Are we making a good trade-off if that protection means preventing lifesaving treatments from reaching the market for decades or more? Does the risk the part might not work somehow justify the loss of life due to the absence of a lifesaving treatment?

A co-worker keeps a blog of his watch restorations. I have no interest in the hobby, but I do have an interest in viewing the work of someone that does. Of particular interest to me is that what he restores isn't high-end stuff, but common watches that might have one particular bit of history that makes them interesting. Radium dials, for example.

Recently launched project based on the milliondollarhomepage concept. You buy a pixel and earn your spot on the internet forever, this time with additional perks.
The evidence seems quite good that this was intentional. The paper found evidence of both using stone tools and fire to shape the notches. Using fire as an aide to woodworking is well known and still exists today in some traditional forms of woodworking. I don't see anywhere in the paper saying the entire structure was burned, just the faces of the notches. They were able to reproduce the chop marks they found with recreated stone tools of the time.

Given we know stone tools were used for more than 2.5 million years by the genus homo, I don't see why it's a stretch to say they were using stone tools on wood 2 million years into having stone tools. Lack of evidence does not mean lack of occurrence. It is very difficult to find organic matter from so long ago given that it normally decays. Furthermore, this is not a radically complex structure either. Something a child could make.

> We interpret the notch as intentional, made by scraping and adzing1 to create a join between the log and trunk, forming a construction of two connected parts. Infrared spectroscopy (Supplementary Information Section 5) provides indeterminate evidence for use of fire in shaping the notch. Clark17 described a similar find, from the Acheulean in Site B, of comparable length (165 cm long) with a “wide and deepish groove” transverse to the long axis, with tapered ends. He interpreted the groove as anthropogenic and suggested it was part of a structure. The excavation of two interlocking logs in BLB5, with shaped ends on both objects supports this interpretation. We know of no comparable construction in the early archaeological record.

The article is trying to figure out why this

> By 2010 — thanks to better design of roads and vehicles, the addition of seatbelts and greater awareness of drunken driving, among other things — the death rate from crashes had fallen almost 90 percent from its 1920s level

which had taken place in the US and other rich countries changed in the US but not in other rich countries:

> But the progress ended about a decade ago, or at least it did in the United States. Even as vehicle deaths have continued falling in most counties, they have risen in this country.

> Here’s a stark way of thinking about the problem: If the U.S. had made as much progress reducing vehicle crashes as other high-income countries had over the past two decades, about 25,000 fewer Americans would die every year.

Larger vehicles do not seem to be the explanation:

> Many of the potential explanations for the trend don’t seem to fit. Cars in this country are large, but they have become only slightly larger since the early 2000s. Drunken driving has not become more common, and roads have not become more dangerous.

EDIT: Here are potential explanations in the article.

• Smartphones. Other rich countries have smartphones, but surveys suggest that Americans use their smartphones much more while driving than do drivers in other rich counties.

They speculate that part of this may be due to almost all cars in the US having automatic transmissions, compared to only 25% in Europe, making it more of a hassle to fiddle with your phone while driving in Europe.

• Drugs. The US has had a big rise in opioid addiction and in the legalization of marijuana. They mention a federal study that found half of drivers involved in serious accidents tested positive for at least one active drug.

• Lack of sidewalks, crosswalks, and bike lanes. Much of the US population growth has been in the Sun Belt where roads often lack those things. Also the increases in homeless mean more people living near traffic.
