It seems like this person is incredibly intelligent and resourceful. Why not just design a new PCB for this instead of modding one? Surely the component cost of 2 connectors and a little PCB could still be in the < $20 range and actually output good quality analog signals? $20 is the same as $3 if you’re also buying CRTs just to play Switch games. This is such a hobby level activity I’m sure people would love a kit + a guidebook, could even provide a 3d printed case.

Why is the EV better? Because electricity transmission is more efficient than gas? What about the losses in the electricity transmission and the batteries and the conversion to motive force in the motor? Is it way less than that 40%? And wouldn’t there be more than 0% losses because refinery -> power plant shipping?

I’m pro EV by the way, I just want to understand your point better. Being able to go all the way to transportation using clean energy is an obvious benefit of EVs. The “dirty electricity” angle is less obvious to me.

The US has no social safety net. Healthcare comes from your employer. Everything is centered around having a job. Opinions on AI diverge significantly and someone’s response to this question would be pivotal to me in a hiring role. The market is not great for job seekers. The hiring manager can wait for someone who aligns with their company’s perspective on this.

Yes, if you get a Toyota and maintain it, it would be expected to make it past 200k miles. They are by far the most reliable cars. Timing belt failures are only catastrophic for interference engines, and most cars use timing chains now, which have a much lower failure rate.

Not in the same request. I often want to turn off 2 lights and the other on, I have to build scenes to do this

Got anything from your orchestrator you could share that’s usable by others? Sounds like how I’d like to work but is difficult to get going from scratch

Traffic is usually caused by adding inefficiencies across a system with little slack - someone brakes too hard or too early, and if all the cars are stacked up, that one brake event can ripple through hundreds of following cars, getting worse and worse because each person brakes more. Self driving cars can perfectly sync up and move like a train. Theoretically there could be no traffic on highways if all cars are self-driving. Rarely is a highway so full that there couldn’t be more cars (eg. The entrance ramps are backed up) which implies the issues are related to the driving flow and not the capacity of the street itself.

I have a fairly large house (2 story 3k sqft) with all cat5e. I iperf’d every run and they could all do 10gb negotiation and TCP, most of the runs could sustain very high UDP rates with low packet loss. There’s just one run (which is the one to the internet) which had a slightly higher UDP packet loss rate. So basically every run can do 10gb fine. Been running the whole network like this for a year. It’s been great! I just need a 10 gig capable NAS. My current one can only do 3.5 or so because it’s a usb 5gb/s which isn’t really 5 gb.

If I was running a physical business and I wrote down each person’s name and credit card number and the exact time and order they placed, that would be pretty invasive and “spying”. If I write down how many units I sold of each item per day, and the volume of transactions by credit card vs cash, it’s anonymized and I don’t think this would generally be considered “spying”, just normal business metrics. How’s the latter much different than anonymized product analytics?

And what is using Confluence in the first place? Your MacBook Pro is faster than a supercomputer from 20 years ago. As we make compute cheaper, we find ways to use it that are less efficient in an absolute sense but more efficient for the end user. A graphical docs portal like Confluence is a hell of a lot easier to use than EMacs and SSH to edit plain text files on an 80 character terminal. But it uses thousands of times more compute.

It seems ridiculous right now because we don’t have hardware to accelerate the LLMs, but in 5 years this will be trivial to run.

Having Kids (2019) 4 months ago

Thank you for posting this. It’s totally understandable and believable that you simultaneously love them and regret some things about it. There’s this insane pressure in our society to never acknowledge the toll that kids have and to never speak out about this. I remember when this article was first posted and how I received it, like I was wrong for not being sure about kids, and that some change would come over me when I had them. Truth is, that doesn’t happen with everyone. Then the world tries to gaslight those people who don’t feel that way into feeling like they’re broken somehow.

I’m sure you love your kids and take great care of them, and it’s not your fault that you feel this way.

It would benefit all of us if this taboo was lifted, so that we could speak truthfully about the impact of kids on families, and maybe then we’d have to provide more support and encouragement to convince people to have them. Not everyone has free daycare from their grandparents or a large social network to babysit or the finances that make having a child less of a burden.

Saying that the paradigms of Python and Haskell are the same makes it sound like you don’t know either or both of those languages. They are not just syntactically different. The paradigms literally are different. Python is a high level duck typed oo scripting language and Haskell is a non-oo strongly typed functional programming language. They’re extremely far apart.

You can also use cloudflare to create a dns record for each local service (pointed to the local IP) and just mark it as not proxied, then use Wireguard or Tailscale on your router to get VPN access to your whole network. If you set up a reverse proxy like nginx proxy manager, you can easily issue a wildcard cert using DNS validation from your NAS using ACME (LetsEncrypt). This is what I do, and I set my phone to use Wireguard with automatic VPN activation when off my home WiFi network. Then you’re not limited by CF Tunnel’s rules like the upload limits or not being able to use Plex.

Cool concept!

I noticed with the Aquarelle brush on iOS, if you swipe fast, you can clearly see the polling rate of the touch events on the canvas. The line looks smooth so I guess you already have an interpolation algorithm going, but this brush darkens as the dwell time is longer so I’m not sure if it’s doubling the points that are reported or what but it looks very bandy/patchy.

At my company it’s lateral.

Lead -> EM

Sr. Lead -> Sr. EM

Principal -> Director

Sr. Principal -> Sr. Director

The pay is aligned with the level whether or not you’re a people leader. To your point though, it may be difficult to go from Principal to Director. I see the lateral moves happen more at the Lead/Sr. Lead levels. They might do a Principal to a Sr. Manager as a trial period with the expectation that you’d be Director after a short time if you perform well. I’ve definitely seen directors become principals as well, so it goes both ways.

One of the main problems I see with tauri is that system web views just aren’t a great solution for a ui framework. Partly because Linux doesn’t have an official webview implementation, partly because the web views across OS versions have differences (eg. Tauri on Linux had a benchmark saying the boot time was 20+ seconds because of the webview, and win 7 and I think even early versions of win 10 do not use the edge webview).

This is a lot of tradeoffs for saving 100 megs.

I understand that we should be good stewards of our customers’ hardware and not waste things unnecessarily, but also have to balance that with shipping something and not worrying about all the edge cases. Most people in developed countries have Internet connections of 100+ mbps, which means the app will still download in <10 seconds.

Does electrobun support using an embedded chromium for the renderer? I went to the project readme and it was really unclear if that’s a currently-supported option and if so, how to use it.
