Pretty much the same trajectory. I started at my T420 around 2010 and that time I just main laptop, computer. Then, as I have a more powerful desktop, this T420 becomes my secondary computer and I started to experience Linux with it. After almost 15 years I end up converted it into a PVE host and run just one or two virtual machines on it and it's quite durable I can still do functional work on it, quite remarkable how a computer can last so long.

This is not secret, almost everyone knows it thousand years ago,
but most of people won't do it. Minimum effective dose is another
way to say be consistent on thing that you feel important. The 3rd
chapter on Atomic Habit also give a very detailed explanation.
And it is so easy to find real word examples:
"Mental toughness and resilience fade if they aren't used
consistently. I say it all the time: you are either getting better,
or you're getting worse. You're not staying the same." [2]
"That’s often all that’s necessary to get the snowball rolling, the
action needed to inspire the motivation to keep going. You can
become your own source of inspiration. You can become your own
source of motivation. Action is always within reach. And with
simply doing something as your only metric for success—well, then
even failure pushes you forward." [3]
In cycling training:
- "I have always been a really consistent rider" [4]
- "The biggest difference in my training in in 2018 to today is
consistency" [5]
- "My Top 5 Tips To Increase Cycling Power: Number one is
consistency." [6]
- Let's finish up with the five key points to how you can improve
your FTP. Number one, be consistent. [7]
- I have three kind of important specs in training, so the first
one and arguably the very most important is consistency. [8]
But if most people agree with this idea, why not everybody do this
way? I think is lacking a clear goal, and a good way to measure it.
I used to be competitive as cyclist, but as I getting older, I
start lossing this part of motivition. Nowadays, I am not training
for FTP anymore, but training for "I don't want to make this f*k
run in this frozen winter". I want myself to become as hard as
Goggins.
Life is short, what would you like to be consistent with?

One day, I'm working on a Linux machine with my Emacs open, I'm using a Bazel to clean my today's to-do list project. And I open the browser to find a person who wrote a blog about Boost.graph which I never heard about, but I'm really interested to look at. I finish this writing, save the buffer and =C-c g= to lunch magit to write a commit message "good day", then pushed to my git repo.
I still remember in high school, we only need two or three equations to solve a free-fall problem. In another book, basically the same question, but someone uses Hamiltonian framework to solve really complex PDEs and couple pages with those crazy equations to basically solve the same thing, and eventually got the same results.
I still remember that was mind-blowing. High school physics is so simple, whereas the Hamilton is so complex. I later on notice that Hamilton is kind of a more standard way to solve the problem. Never mind, I'm not an expert on it, but I'm just kind of amazed by the Hamiltonian mechanics.
It descripts a system using the energy concept. The total energy of the system, which is the sum of kinetic energy and potential energy. Its formula often looks like H = T + V, where T represents kinetic energy and V represents potential energy.
Both the quantum mechanics and molecular dynamics have shared a similar concept.
In structural mechanics, we use the virtual method to calculate the hyperstatic structure to determine displacements in a structure, given forces acting on the structure. Another kind of Hamiltonian.
After watching his speech, the first thing that came to my mind is one of the speeches that was given by James T. Kirk, which I had no idea which episode it was in, but I do remember the core meaning of that speech. So I use chatGPT to actually help me to find it by just single one question. And it works! And here's the thing I want to share with the the audiuence.
"They used to say if man could fly, he'd have wings, but he did fly. He discovered he had to. Do you wish that the first Apollo mission hadn't reached the moon, or that we hadn't gone on to Mars and then to the nearest star? That's like saying you wish that you still operated with scalpels and sewed your patients up with catgut like your great-great-great-great grandfather used to. I'm in command. I could order this, but I'm not because Doctor McCoy is right in pointing out the enormous danger potential in any contact with life and intelligence as fantastically advanced as this, but I must point out that the possibilities - the potential for knowledge and advancement - is equally great. Risk! Risk is our business. That's what this starship is all about. That's why we're aboard her. You may dissent without prejudice. Do I hear a negative vote?"
- James T. Kirk Return to Tomorrow (1968)
I'm listening to her book The worlds i see: curiosity, exploration, and discovery at the dawn of ai. So right now, I'm just in the middle. She's Starting from physics, but eventually found something interesting internal world for a person, which lead to the road to artificial intelligence. I have pretty much the same experience like her. Starting young, falling in love with physics as I get older. I also noticed a huge motivation to learn Myself. The thing in my head, how it works, how it behaves, how I react to certain external world stimulus. Yeah I'm still in the process to to her book and try to understanding of this new technology and immerse myself in this new things and try to do some interesting stuff.
How about https://pirateweather.net/en/latest/ ?
Does anyone have a compare this API with the latest API we have here?
So for a daily user, to make it a practical usage, let's say if I have a local measurement of X, I can predict, let's say, 10 days later, or even just tomorrow, or the day after tomorrow, let's say the wind direction, is it possible to do that?
If it is possible, then I will try using the sensor to measure my velocity at some place where I live, and I can run the model and see how the results look like. I don't know if it's going to accurately predict the future or within a 10% error bar range.
Dude, this is crazy.
Maybe it's naive for me. Every time we talk about a simulation, we got an accurate model and we have some model validation to run our model. The next big question is, okay, what can we do with those models? If we can do CFD simulations, we can use that tools to build fast car, to build efficient SpaceX rocket to reduce the cost, but in terms of this cosmology galaxy formation, what can we do with this model?
One simple idea for me is to, okay, is there any significant difference from a large-scale model with at the galax scale and the model we have, let's say, simulating a von Karman vertices because both of them are showing very similar structure. Yes, that's an idea of comparison.
I was thinking about a use case for this device. First thing, it's about water resistance. Is this waterproof? So I'm thinking about its relation to, let's say, a smart glass you have. I mean, they both can take a picture on camera. They can both understand your voice. You can use it as a microphone. So what's the thing that a smart glass is not able to provide?
It's so cool. I was wondering if we can make crawler tool much easier and better. It's more similar to the "human" way to interact with a website.
"..., find the 4mm Allen (HEX) key". Nice job.
url?
Well, it looks like something, but if you're not talking to me that it's water, I can not say. I just have a strange feeling about it. It's not water, it's something different. I don't know why, maybe it's the way you visualize, or maybe it's just the two-dimensional nature of the simulation. Or maybe it's the reflection, maybe it's the post-processing procedure. We don't have some ray tracing, we don't have those normal calculations, reflection index, all those crazy stuff.
I'm not going to delete my .emacs file even though it is ugly, it just works.
It really depends on what data you're processing with. For someone whose data is hundreds of tetrabytes, the workflow to saving those data and manipulating or retrieving those data as request becomes very tricky, very hard task, especially when you think about the backup time. Maybe you can scale down the concept of L1, L2, L3 cache but at a higher, bigger scale. And always figure out what's the most important things to you at different stages and make those choices. You definitely compromise something in order to have large scale of data. So, again, it's about figuring out what's most important to you.
I do see your point and it is true that every product is going to be more mature, more complete for the later publication. But things of a first generation product like this is going to be a huge risk for a lot of people. But the things I want to talk to myself is probably if I can pick up one thing or maybe one or two things that this device can solve that probably doesn't have a good solution in the market, then just go for it. And if it is affordable, then go definitely do it. The upside of doing this is you cannot change your workflow in the early stages. So if you consider the time you put into that product in this new workflow, the things or the productivity you gain from this early experiment is going to be more productive. But gain, it's a risk.
I see the pattern is that C is complained by most of people. And there is another type of programming that is that, which people never talk about. So just by talking about, regardless it's positive or negative, there is a tension in there and it's expectation, it's our will to kind of devices or this technology came into being. So eventually it will become part of our life and I hope that day comes sooner and this company will not disappoint us.
Taking a positive sign because now the consumers expectations are high and if they not deliver what they promised here then they're gonna have a huge trouble so as a consumer it would be nice if the consumer can provide some our expectations to say how to show our interest and kind of motivate them to build a better product.
Unfortunately, this is the reality. Most people will choose the comfort over those discomfort. Just like the 99% moving matrix, going to select the blue pills over the red pills. Even the people who choose the red pill change their mind. It's just a big lever to enlarge those points.
We're really missing the point here. Yes, that device can't do better. You can't do that with your friends together. But there's some similar in America right now. You can just jump in and in 2 or 4 minutes, and that kind of experience. Why to bother this kind of thing, this new tech? Doing things together is good, I think that's the main selling point of these devices.
Good point. Remember, they demonstrate that they put these devices as a module, so I'm not sure it is possible to make it a portable device. You can easily get rid of part of the panel part and put it into a very small bag, and the rest of things can just like a rope, something similar to those things, you can easily fold them into small spaces. I'm actually thinking the same thing as you. The real revolution is going to be directly connecting our brains, so we don't bother using our eyes to kind of sensor our physical world, that's kind of like the matrix. I'm not sure that's going to be in the near future or in the life we have, but I'm really looking forward to that kind of scenario.
I completely agree with you about the tiredness of the eye or fatigueness of the eye. It's really hard to imagine someone wearing this kind of device for a very long time without feeling any pain. I'm not sure exactly the reason why this pain came from. But I think the question we face is going to be maybe the next big thing for humans, which is going to directly connect all those sensors directly connected to our central brain without using the eye. But that's kind of a science fiction thing. I'm not sure I'm going to have a chance to experience those things.
I completely agree with your point about risk. When we're talking about risk, the opposite of risk is a great benefit, just like a starship. Captain Kirk said great risk we have, the more potential gain we probably gain. Stand-up work environment is also huge for me. I don't like sitting all the time in front of a desk. But I'm not sure if I sit down, all the benefits gonna last. Maybe it's just a choice. Maybe I can sit down doing some different kind of things. Or maybe I can lay on my bed, just do something else. The gesture interface has to be rock solid. I agree. Especially you're already doing something more fine-tune level things.For example, you want to manipulate a 3D object, but I think we can, or the engineering can finally overcome those difficulties by using those optical algorithms to track, to kind of think about a new way to interact with computer. Actually, if you think about the way we communicate with computer, all we're talking about is the keyboard, but does the keyboard is the only solution to all the problem we have? I don't think that is the only problem. The battery lapsed two hours, I'm not sure what exactly they mean. If it's just two hours, maybe it's a replaceable charge or something like that, maybe we can bring a bigger external battery. I'm not sure, but if it's just only working for two hours, that's going to be some potential issues here.
Unfortunately, I strongly disagree with this comment as well. It is because how portable this device is, you have to think about the... Imagine you have an infinite amount of screen just in your pocket. What you say causes what you do, and that's a huge thing.
exactly I don't know how many like 4k monitor is just sat in front of you and that physical device is only I don't know smaller than a 10 inch iPad so that's it's incredible
That's definitely a big concern about the physical pen. If it's too heavy or if it's too hot, it will overperform or perform some CPU intense work. Also the fitting using your eye with such a close contact with the digital device is another issue.
