tantony··on Ask HN: How to become good at Emacs/Vim?
I dabbled with neovim on and off for a while - kind of following the same logic as you, wanting to be like many people I saw on Youtube. It never really worked since I was really comfortable with my existing workflow - vscode + iterm and "swiping" between screens on macOS. I was super-fast with the Macbook trackpad with its sensitivity turned up to the max.

It finally clicked when I started a job where I had to use a windows laptop with a linux VM as my primary computer. I found that using vscode either within the VM or over "Remote-SSH" from windows was severely cramping my productivity. So I switched to NeoVim+Tmux cold turkey (SSHing into VM using "Windows Terminal"). I set up some shortcuts that made sense for me somewhat from vscode (e.g. Alt+<number> for switching "tabs", alt+hjkl or alt+arrow keys to switch between tmux panes etc.). Within a couple of weeks I was back to my old level of productivity.

My usual setup has neovim on the left and a terminal in the right pane. Adding more panes vertically or horizontally is super easy as well. This may not be the most optimal setup, and there are still a few pain points from time to time - particularly with the LSP/"intellisense" stuff. But it works for me.

Oh and when I am coding on my MacBook Pro at home, I still prefer to use vscode + iTerm.

Some resources that helped:

"Practical Vim" by Drew Neil. I didn't read it cover to cover but I have scanned through it enough to pick up the important stuff.

You could use a Roth 401k to supplement that. And then rollover that into a Roth IRA if/when you change jobs.

tantony··on New MacBook Pro has first ‘DIY-friendly’ battery replacement design since 2012
I tried switching to KDE yesterday (still in PopOS) and it's been a much better experience so far. I was able to customize a bunch of stuff including dock/global menu to be more macOS-like which is what I prefer, and the touchpad also seems to be much better integrated. I will look into Manjaro as well.

Thanks!

What distro are you running?
tantony··on New MacBook Pro has first ‘DIY-friendly’ battery replacement design since 2012
I recently bought a Framework as a replacement for my 2012 MBP. I ordered it a few weeks before the new M1 announcements because I liked their philosophy. And the hardware is, in fact, great!

But the Linux desktop experience has been ... frustrating to say the least. And I say this as someone who has used linux in the terminal at my job every day for 5+ years now. It's ridiculous that the software experience still cannot match my 9 year old laptop running macOS Sierra on a 2.5GHz Core i5 and 8GB of DDR3 RAM!

I am running PopOS 21.04. There's inconsistent keyboard shortcuts, lack of touchpad precision, glitchy touchpad gestures, inconsistent fingerprint auth and more. Just on Day 2, I somehow ended up with a machine that somehow took 30+ seconds to go from login to desktop and 3-4 second lag when typing with 100% CPU usage when running any GUI app. The only way to fix it was to completely reinstall the OS -- I have no idea what caused this. I have now found some usable options for implementing my preferred touchpad gestures ("fusuma") and system-wide keyboard shortcuts ("kinto.sh") though there are still many quirks that are irritating.

I like Framework's approach, so I supported them by buying the device. I promised myself I will keep daily driving it for at least a month to give it a chance. If it keeps getting on my nerves, I will sell it and buy one the of the new 14" MBPs. Life's too short to spend hours upon hours fiddling with configuration files and reinstalling operating systems to get basic functionality working.

I have a Framework laptop on order. But I must say that I am very tempted. If my attempt at daily driving linux doesn't work out, I will probably get the M1 Max 14'' MBP.
tantony··on A New Bootable USB Solution
I am not sure if this is what you are asking, but you can create a bootable USB with ventoy on macos using Virtualbox.

Create a VM with no storage, boot from the ventoy ISO, pass through the USB port from the host machine. I used this a couple of days back to create a bootable ventoy drive from my Macbook Pro.

tantony··on Why Carmakers Can’t Transition to Newer Chips
If the radar data conflicts with what vision is saying, which one do they trust? They have shown that their vision stack has surpassed what they can do with radar. So "fusing" that data in only makes it worse when it gives conflicting information.

If it makes sense energy wise, it makes sense distance wise too. If the EV can go 4 miles for every one mile towed, then why would it not make sense?
tantony··on Rivian S-1
They can be almost 100% reused. In fact, given how valuable the metals are it would be cheaper to do so than mine for them . There are multiple companies working on this. E.g. https://www.redwoodmaterials.com/

Most reviews I have seen have shown them to be extremely unreliable with multiple chargers frequently out of order at charging stations.

E.g. this recent video by MKBHD https://www.youtube.com/watch?v=vXzuFprlyrw

tantony··on Why Carmakers Can’t Transition to Newer Chips
> Charging efficiency isn't 100%, so you'd have to tow it further than the range you need

That's not how it works. You basically get 5 mpg or less on the truck, while the car charges at significantly higher rates than the speed of the truck (in mph), because the car is more efficient at using the energy.

https://insideevs.com/news/514727/tesla-towing-70mph-fast-ch...

Towing at 70mph in the above example was charging the car at 65 kW. That's equivalent to ~260-270 mi/hr of charging rate assuming 250Wh/mi.

> If they were so passionate about spending money to make the safest cars, they'd be doing sensor fusion.

That's your opinion. They have shown data where the information from radar was of a lower quality than what their vision stack was providing (e.g. lack of vertical resolution). Watch their AI day webcast for examples. Their current vision-only stack has been validated with LIDAR ground-truth data.

The cards can be linked to specific vendors so that no one else can charge it. And you can also block the individual virtual cards in the scenario that they refuse to cancel auto-billing. It's more of an on/off limit than a granular dollar limit.

tantony··on The Framework is the most exciting laptop I've used
> If Framework opens this up for other companies to make modules

From what I can tell, they already did that: https://github.com/FrameworkComputer/ExpansionCards

> USB port module with an integrated Logitech wireless mouse receiver

This guy seems to be making something like that (minus the USB port): https://www.youtube.com/watch?v=0_uOzNt-xwY

People are working on some interesting stuff. Example:

The engineers at framework seem to be very active on the forum engaging with the community.

tantony··on Ask HN: Satellite ISPs Worth It?
Is Starlink available in your area? Their satellites are in a much lower orbit (not GEO) and so the latency is much lower. It is supposed to be around $100 per month with a $500 up-front cost for the terminal.

I am not an expert in this field though and have no idea about the reputation or history of that journal.

tantony··on Optical-Cavity-Induced Current
While the topic is interesting, I had somewhat the same impression from certain parts of the video.

I would love for this to be real, but until it is verified I remain skeptical. To quote Sagan, "extraordinary claims require extraordinary evidence".

However, I do not know how reputable that particular journal is.
