That's hard, I'm sorry you have that struggle. I am about as far away from an expert on the brain as it gets, so I don't want to pretend to have wisdom there. The only thing I can say for myself is around Duḥkha, or that life is suffering.

Navigating the balance between self improvement, and being okay with the idea you may never improve to the point you want is hard. I know as much as I wish I could run a 5 minute mile, I was incredibly sedentary in my teens and 20's. It bothers me that I may never become "elite" in fitness because of my past, and that's just a fundamental barrier for me now.

My current thought is trying to find my personal worth in the journey of attempting self improvement, and not having an absolute goal of "I must be this smart" or "I must be this fit" to consider myself valuable. That mindset is easier said than done, though.
We do need a deep analysis. Roman concrete is self-healing, and this article explains why. And the reason is exactly the opposite of the one you postulate.

Property is indefinite (it exists as long as the legal system remains the same); fresh water is a limited resource. Care to explain which "same reason" applies to finite and infinite resources equally?
The cost of this blade setup means no one will buy it. Very high cost to purchase and equally high cost to maintain for such a tiny benefit. I had a laugh at the noise reduction claim. Sure, it will reduce noise, but the open exhausts on planes are the loudest part unless some nitwit is screwing around with the pitch.
the article talks about evidence which has always been present in evaluations of Roman concrete which was "disregarded as merely evidence of sloppy mixing practices, or poor-quality raw materials," and this kind of thing REALLY infuriates me, as a layman.

if you don't know how to make Roman concrete, don't assume anything about what you see in Roman concrete while you're trying to figure out how it was made.

The modern-day belief that we are superior to humans thousands of years ago is just an absolutely insane idea, to me. we are more technologically advanced because we have more shoulders of giants to stand on, and we are NOT smarter or more clever than humans of 5000-10000 years ago. we just aren't.

as soon as you believe that we are superior to our ancestors, you dismiss the evidence you are looking for as "sloppy mixing practices, or poor-quality raw materials" and you prove modern-day humans as inferior, or at least you prove your own efforts as careless and incomplete.

leave no stone unturned when you are trying to understand something you do not understand; your lack of understanding could be due to your false assumptions.

Yeah there are a lot of differences, I wouldn't normally bring up the comparison. My point was just that the turnover is not as bad as the other commenter was implying.
That is... not a smooth ride.
Planar magnetic headphones with large drivers, specifically Audeze LCD-2 with denser foam embouchures (ear pads). They wrap my ears in a very comfortable and isolating way; they are formidable in terms of delivering sound the way I want for the music I like; they are very responsive to EQ, hence tuneable to a lot of ears. And their downside of being heavy surprisingly aligns with pomodoro timings: if my neck is getting tired from headphones then it’s time to have a break.

(Another downdisde: these headphones are “open”, meaning they have no hard enclosed outer shell, so your coworkers will hear what you hear, but if you work from home and/or buy a closed back version then they might work for you.)

As for all the espresso machines comments, I totally get it, but folks, might I suggest you just get an Aeropress and give it a try :)
I was about to say this.
I'm wondering how to apply this in my life.

People -> Should the contracted teams I work with have more frequent or deeper touch points? Can I make it even easier for customers and strangers to contact me? Do I generally signal that I'm open and willing to listen to the people in my life?

Places -> Is there a convenient way to get around town that I'm neglecting?

Ideas -> How can I create rapid channels of info from more distant communities or corners of the internet? What newsletters should I subscribe to?

The idea here is that we need to manage our space – geographic, social, conceptual – and that it may serve us to expand our zone of access.
I ended up getting two Dell 30" 4K displays and a monitor stand to mount one above the other, next to my laptops (also stacked), and that's been a pretty nice work setup for the past year. I did have to end up doing two USB-C to HDMI adapters plugged into the laptop to drive them, the docking station can't do dual 4K output (older Dell XPS15, sounds like the next version they made of it does).
Sounds like the chemistry is important

> Previously disregarded as merely evidence of sloppy mixing practices, or poor-quality raw materials, the new study suggests that these tiny lime clasts gave the concrete a previously unrecognized self-healing capability.

> As soon as tiny cracks start to form within the concrete, they can preferentially travel through the high-surface-area lime clasts. This material can then react with water, creating a calcium-saturated solution, which can recrystallize as calcium carbonate and quickly fill the crack, or react with pozzolanic materials to further strengthen the composite material.

Microsoft probably have also pretty good idea just how many computers running their operating system is being sold or licensed. What are the licensing numbers for Office suite and 365. Outlook and AD seats, Teams.

I've been using the PARA system from Building a Second Brain by Tiago Forte for all of my new notes and interest hoarding. After I've read a link, I'll quickly file it away into an inbox with some useful snippets on the page. When I'm bored, or have additional free time, I'll summarize the highlighted points and then move it into either a Project, Area, or Resource.

Sometimes I just read stuff and don't bother with the notes. As long as I have an inkling of what the thing was, I'll be able to find it later.
When spending down money you get the reverse of cost dollar averaging. In a good year you might sell say 1,000 shares but in a down year you might need to sell twice that to take out the same money. This means more of your shares are sold in down years than good years.

This is why people say to increase the bond ratio in retirement, but that also reduces expected returns.
This is not meant as a criticism, hopefully more of an inquiry if you so choose. Is it possible that your 'feeling' of your brain being irreparably damaged is actually factually incorrect? And that your assumptions/model of the plasticity of the brain may be wrong and skew a bit negative?

Is it possible that these negative thought patterns are holding you back? Awhile back, I became aware of some irrational negative thought patterns I had myself, and worked on reframing them, and it helped immensely w/ confidence.

Here's a random link on the general idea (can't vouch for all the content, but it captures the idea of this pattern): https://positivepsychology.com/cbt-cognitive-restructuring-c...

[Anshul from the Codeium team here]

We launched on HackerNews a month ago to a decent response (https://news.ycombinator.com/item?id=33885676) and one of the biggest asks we received on our Discord was to make Codeium available in places where Copilot or other alternatives are not. The top of that list was standalone Jupyter notebooks, popular among data scientists and students, and so we made it a priority to build out this capability. So now any developer can (for free) enjoy the same AI-powered autocomplete on Jupyter notebooks as they do on popular IDEs like VSCode and JetBrains.

We are happy to answer any questions, and would love to get feedback from the HN community!
Exactly his point.

In his example, a prominent group of blue-chip companies grew for 17 years and their valuations remained flat (and net of inflation, declined).
Nice work, Marcus. This is really impressive. Dig the polish on everything.
i don't really worship anybody like that, but some of the people you dumped into the same category were scammers, others have actually built something very concrete of value. Satya, as far as I know, managed to turn Microsoft around after a very bizarre rule of Ballmer, so I know he's not a complete idiot and probably has something interesting to say.
This is a shockingly high amount of FUD but little facts.

Lets start at the top shall we?

Diesel doesn't "burn" like gasoline does.

"If you toss a lit match into a puddle of diesel fuel, it'll go out."

You need to atomize it first, or heat it up a lot so it starts to "flash" or it wont "burn".

So, a firetruck with a large diesel tank is fairly safe because it takes a LOT to get it to start burning. At first all the heat is simply absorbed by the diesel slowing warming it up until it reaches its flash point.

Next, your temperatures are beyond MESSED UP.

6.9% as geometric doesn’t look so attractive. I wonder if a basket of bonds could perform better with less drawdown.

With my most recent iteration, I have started using my website more as a mental decluttering tool than a show-tell medium. The wesbite is a bunch of markdown files spiced up with Next.js and my first attempt at structured navigation. I keep a similar private one.

I've now been rethinking of reorganizing into a flat heirarchy + what I like to call "theme portals" - essentially big picture entrypoints into details. This avoids a long list of scattered blog posts. The orrganization style of clean overarching themes like tech/math etc. isn't working for me.
Sure, but not really the policy outcome that people are thinking of when they talk about solving the "homeless problem". The guy passed on in the subway car next to his own feces is not going to be helped in any way by these policies.

There are no good solutions here that respect the rights of the individual and also our collective right to live in a civil society. Involuntarily detention through the criminal justice system (horrifying) or the mental health system (completely dehumanizing) are the best tools we have, other than having compassionate people who will devote time and effort and individual attention to the victims of mental health or pathological substance abuse problems.
This is super impressive; nice to see folks who've come from a Bukkit plugin development background too :P

Few suggestions:

The description you've given us here on HN is so much better than on your landing page here: https://tablane.net/ The first thoughts I had were: "Okay, Productivity. And it's 'Next Generation'. What does that even mean? The screenshot is pretty but I don't really understand what it's showing". I then read the GitHub description "Tablane is a workspace that adapts to your needs. It's as minimal or as powerful as you need it to be." and ended up even more confused. What is a workspace in this context? It's great it can adapt to my needs, but I don't know what it even does. Once I read the description here on HN, it made a lot more sense. It'd be useful to explain the hierarchy of workspaces/spaces/tasks a bit more.

There are a few dialogs that don't seem to support keyboard controls (like Enter), I've opened a PR for this.

When I try and run it locally to test my PR, it seems to complain with an "AppError: Invalid access token" on the backend. I get a "Something went wrong" error message (and the XHR fails with a CORS error). What am I doing wrong?
I also have this problem and has been something I've been thinking about for some time, and have started building.

All the comments here have been great validation, that there is others with a need, which is encouraging.

I've mostly been working on the data aspects, so not much to see as yet, but if a new approach to this is of interest to you, please signup.

I think the other solutions out there focus too much on note taking, and manually organising stuff, hopefully I can create something more compelling for the rest of us!
I suggest that you check out the work of Sebern Fisher, particularly her book "Neurofeedback in the Treatment of Developmental Trauma", which contains several cases of significant cognitive recovery after trauma. Bessel van der Kolk also has a chapter on Sebern's work in "The Body Keeps the Score", his best-selling book which surveys trauma therapies and the evidence on them.

After reading that material, I sought out a neurofeedback practitioner who works in the style that Fisher and van der Kolk recommend. I've found it helpful and recommended it to family and friends. Several have reported cognitive improvement, including one who said that her "brain fog" was gone.

I've looked into the research literature on neurofeedback and it's unfortunately rather poor, but there are some interesting recent results in the work of Ruth Lanius. My own feeling, FWIW, is that neurofeedback+psychotherapy is able to reach levels of the nervous system that talk therapies alone cannot, because many effects of trauma are encoded in nonverbal parts of the brain.

There are many products out there that use the name "neurofeedback", but if you contact the company the makes the system that Sebern Fisher works with, they will send you a list of practitioners in your area. The recommended approach is to find a psychotherapist who incorporates neurofeedback into their practice. There aren't many of those, but there are some, and in my experience it makes a big difference, so big that it becomes a puzzle why this practice is still so little known.

Whatever you end up trying, please don't give up. It can take a long while to find something that works for you. My experience was that most therapies I tried just didn't go deep enough, and my problems would "snap back" into place no matter what happened in the sessions. It was frustrating. What's different about neurofeedback, in my experience, is that it's able to "talk" directly to the brain in a way that is uncorrelated with the rest of what therapists do. I'm not saying it's for everybody, but it's worth a try if nothing else has helped.
Wow this is amazing! Why not charge money for it?
> if you can't figure out how to gain from an influx of wealthy, highly-educated, low-criminality, nerdy tech workers, then that's really on you

Oh, people are gaining from them. It's just that the people gaining are generally the people who already have political power.

Someone who owns their home doesn't mind seeing land values quadruple, thanks to this influx of free tech money.

Someone who is renting, so that they can save up money for a downpayment, whose service industry wages have not quadrupled in that period of time minds very, very much.

This is what therapists have told me, but when my mind totally blanks when asked a question in a meeting, or when I can't vocalize a coherent thought without stumbling over myself, or when I have to read a paragraph 20 times over for the information to stick, I have a hard time believing it's just a negative self-perception.

You can't express the equivalent of Linux's rcu_dereference primitive in a way that avoids data races without using memory_order_acquire (or memory_order_consume, which is treated like memory_order_acquire in all implementations, and is fundamentally broken as I link to in my sibling reply). With a memory consistency model weaker than TSO (e.g. ARM, RISC-V, POWER), this imposes unnecessary overhead and eliminates some of the benefits of RCU.

To work around this flaw, you can use inline assembly, implementation-specific "compiler-only" barriers, etc. but that's outside of the language. It also forces the compiler to be much more pessimistic about optimizations than is actually necessary to preserve dependency ordering.
Cool, many thanks again!
In this case, the original poster went on a complete tangent without addressing the topic of the article at all.

So my vote is for the person who pointed this out as he's most likely right in his deduction.
for sure!

My grinder is a Weber EG-1. It has really large (80mm) flat burrs. Very forgiving; like I don't have to be dialed in perfectly for the espresso to be very good. It's essentially a cafe quality grinder, but optimized for a single-dose flow.

My machine is an Olympia Cremina, which is a manual lever machine. I've modified it with a pressure profiler to control and track the pressure of the shot I'm pulling. All that manual control is really nice for the kind of coffees I like which are usually naturally-processed light roasts. However, manual levers are not for everyone and have a definite learning curve.

If you're curious about either of those, James Hoffmann has good reviews of them both on YT.

I really enjoy the nerdiness and tactile feedback of the manual lever, but if I didn't want go manual, I'd look at a Decent DE-1.

If I had to shave a bit off that budget, I think I'd go with a Rancilio Silvia Pro X, which is half the cost.
Having good “small” rational approximations is actually a characterization of transcendental numbers: there are upper bounds for how good rational approximations to an algebraic number can be as the maximum allowed denominator grows, so by proving that this bound is violated for your number you can prove it’s not algebraic; that’s how people initially went about constructing transcendental numbers and—later—proving π and e were such.

(Nowadays, it’s easy to construct a transcendental number because it’s easy to construct a noncomputable one; constructing a transcendental computable number still requires additional ideas such as those bounds—I don’t really know of a simple way to do it.)

To answer the question for anyone interested of what programming language it is written in, Stack Overflow did a Q&A with Tarn Adams (developer) where they asked this, among other things.

Q: What programming languages and other technologies do you use? Basically, what’s your stack? Has that changed over the 15-20 years you’ve been doing this?

A: DF is some combination of C and C++, not in some kind of standard obeying way, but sort of a mess that’s accreted over time. I’ve been using Microsoft Visual Studio since MSVC 6, though now I’m on some version of Visual Studio Community.

I use OpenGL and SDL to handle the engine matters. We went with those because it was easier to port them to OSX and Linux, though I still wasn’t able to do that myself of course. I’m not sure if I’d use something like Unity or Unreal now if I had the choice since I don’t know how to use either of them. But handling your own engine is also a real pain, especially now that I’m doing something beyond text graphics. I use FMOD for sound.

All of this has been constant over the course of the project, except that SDL got introduced a few years in so we could do the ports. On the mechanical side of the game, I don’t use a lot of outside libraries, but I’ve occasional picked up some random number gen stuff—I put in a Mersenne Twister a long while ago, and most recently I adopted SplitMix64, which was featured in a talk at the last Roguelike Celebration.
