I have TAoE (but probably 2nd Ed, as I’ve had it for some years) and it is both educational and very dense. That said, I bought “Learning the Art of Electronics: A Hands-On Lab Course” and really like it. There’s a good bit of practical, ac

The bit that sticks in my mind is a shot of some giant pipes heading up into the sky, to a ship. Apparently they were taking Earth’s water? And I think someone read a gauge indicating that one million gallons/second were flowing? I was

I’m a pretty firm believer in first learning the rules and only then, learning when it’s “OK” to break them. You’re probably not doing your kids any favors by skipping the first step.

How can it not be obvious by now that if you want to control the experience, you need to own and control the hardware and software? Why would anyone ever trust anything else to remain stable over the long term?

Do you really believe that homeownership is for everyone? It’s not. Hell, it is not for some of my friends in tech. You’ve got a lot to maintain, a lot of work to do, a lot to keep track of. That either means money, or pretty broad DIY skil

That’s where I live and to my knowledge, this is true. We haven’t got a monopoly though. Lived in Atlanta for many years and once asked around a bit. Pretty sure I could not legally do so much as replace a receptacle by myself. From what I

I’ve seen lots of cases where I or others can do better work than “the pros”. Some of it is because we’re working for ourselves on our own stuff and care more. But a lot of it is speed. It’s very possible to do a great job if being slow doe

They’re learning how to build this type of launch site at the same time they’re learning how to build this type of rocket. These guys are not clowns. Their Falcon 9 is arguably the most reliable rocket ever built. On top of successfully per

Everything will not be perfect the first time. Waiting for perfection guarantees that no progress is ever made. They’re going to launch, it’s going to do whatever it does (hopefully complete all test objectives!) and then we’ll have real da

I’m with you on that. I live in Evanston, IL. For those unaware, it is the first city north of Chicago along Lake Michigan. Hardly a backwater. On the one hand, I have two competing cable providers (RCN/Astound and Comcast/Xfinity

This is a subject that gets a lot of reviewer attention and results in considerable gnashing of teeth. Yet for most users, how often do we generate many-gigabyte streams of sequential writes? It’s just not a usage pattern worthy of infinite

Hah! I’m sitting here waiting for eye surgery and figured it was slow hospital wifi. You’re right, though. Other sites are quick! If someone screws up and kills me, HN will be the last thing I remember. ;-)

Speaking as someone with a hefty dose of ADHD and anxiety, I can only dream of wasting a mere two hours per month. It blows me away to think of two hours being a major distraction for anyone. Count yourselves lucky!

It's called "Hacker News" for a reason. We get to be all practical and stuff at our jobs.

Excellent work once again. Would have loved to find something like this when I was a student... back when computers occupied entire desks. This seems similar, if not identical, to the free streaming box I told Xfinity they could keep. Might

It doesn't have to deliver 10gb/sec to be worthwhile. 3 gbps is easy and already more than a 2.5GbE link can handle. And the prices for those switches still exceed what's available used for 10gbps. I've got an ICX7250-24

I run sfp+ 10 gig at home. You can get SR transceivers for maybe $6ea last I made a purchase. Appropriate LC fiber patch cords are similarly dirt cheap.

I'm with you 100% but we're fighting an uphill battle. For the couple of years pre-Covid, I alternated between a 15-mile bike ride (each way) and a walk->train->walk commute. It was wonderful, and great for my mental and phy

Along this line, I find their cancellation of the Oregon lab and Haifa dev center to be concerning. Sure, in the short term that stuff eats money. In the long term it means you stay relevant.

Personally I am excited to see this, but I wonder if the optics will kill it? People get upset enough about reactors that don’t move and live inside huge structures of reinforced concrete. Can we convince this segment of the population that

One of the magazine ads for the original Macintosh highlighted this. Iirc, a 68k in all its glory was shown next to a plastic DIP 8088. It made enough of an impression on my ~12 y/o self to still picture it today. Well, look at that. I

I had a very early Apple //e (purchased 1983) and remember some funny things in the manuals. There was a glossary entry for Write-Only Memory. This contained an entire brief story about how it had been invented by a Prof. Farnsfar
