Weight training equipment lasts decades all the time. It's just big piles of metal, it's not hard to get right. What actually prompted the engineering-CYA "should" is if the Android tablet is controlling some sort of rob

by jerf 9mo ago
The major problem with sticking an Android tablet on to exercise equipment is the difference in life spans. Android tablets are generally going to last you 4-5 years. Weight equipment should be able to last decades. There is some simple &am

The golden ratio is very mathematically interesting and shows up in many places. Not as prolific as pi or e, but it gets around. I find the aesthetic arguments for it very overrated, though. A clear case of a guy says a thing, and some othe

It's counterintuitive but something becoming easier doesn't necessarily mean it becomes cheap. Programming has arguably been the easiest engineering discipline to break into by sheer force of will for the past 20+ years, and the p

The Great Lakes have a management principle that is basically "You can use the water of the Great Lakes by permission as long as the water remains in the watershed." And permission is not automatic either. The reason for that to a

"why go to the shed" A good question but there's a good answer: Debugged and tested code. And by that, I mean the FULL spectrum of debugging and testing. Not just unit tests, not even just integration tests, but, is there a u

Isn't SQLite a de facto standard? Seems like it to me. If I want an embedded SQL engine, it is the "nobody got fired for selecting" choice. A competitor needs to offer something very compelling to unseat it.

So what is the solution? Is the author demanding that people work for them for free to do the sustainability for them? Because that sure sounds like the only way to "resolve" the complaint. "start treating it as what it often

My local karate school used them in the COVID era to build an app for practicing at home. I've used it off and on, though the occasional oblique reference to COVID is a bit amusing sometimes. Never mentioned by name but there's an

If you want to see what a JS interpreter in Go would look like, you can look at https://pkg.go.dev/github.com/robertkrimen/otto and https://github.com/dop251/goja . Of course they aren't

XPath may have "failed" for general use but it's generally well-enough supported that I can find a library in the common languages I've used when I went looking for it. In some ways the hard part is just knowing it exist

About a year ago I had some code I had been working on for about a year subject to a pretty heavy-duty security review by a reputable review company. When they asked what language I implemented it in and I told them "Go", they jok

If we get to that point, there won't be very many CEOs to be discussing. I was just referring to the near future. I think the honeymoon AI phase is rapidly coming to a close, as evidenced by the increasingly close hoofbeat sounds of LL

by jerf 9mo ago
You will need the CEO to watch over the AI and ensure that the interests of the company are being pursued and not the interests of the owners of the AI. That's probably the biggest threat to the long-term success of the AI industry; th

There are a number of little projects like that but I'm not aware of any that have attained liftoff. Javascript was a weird exception, being rigidly the only thing available in the browser for so long and thus the only acceptable &quot

I think this is a specific example of a generalized mistake, one that various bits of our infrastructure and architecture all but beg us to make, over and over, and which must be resisted, which is: Your development feedback loop must b

We are "just fine" with blurry details, on some level... but a lot of processing a movie holistically comes from that level of detail being present. Even if few people walking out of the theater could put their finger on why the w

Perhaps the most distinguishing characteristic of HTML5 is that it specifies exactly what to do with tag soup. The rules are worth a glance at some time, just to see how rather absurdly complicated they are to do the job of picking up the

Fairly common from what I've seen. You're supposed to ooh and aah at the number of options they give you and not ask question about what they're actually going to be worth. This is one of the bigger reasons HN tends to advise

I expect AI ads to start with blindingly obvious overwhelmingly excited endorsments, but it won't take long for that to show up in the metrics that won't work very well past the initial intro, and they'll get more subdued ove

Sum types can be put into 1:1 correspondence with the integers, barring the inclusion of a non-enumerable type in a language's specification that can be used in sum types. However I would observe that this is generally a parlor trick a

Another thing companies miss is that the second-value is priced in to the price. If I know I can resell a thing for some value, that makes it more valuable than if I can't resell it all, and I can pay more for it. Contrary to what the

I think a lot of people assume Kubernetes must be a good Go example, because it's so big and successful. But it started life as a Java project and was ported into Go, and that shows in some of the architecture, Also, in general across

Another problem I'm starting to see lately is accounts on Reddit posting vague positive comments to farm karma, make the accounts look real, run cover for other AI posts from the same account, etc. I'd love to see a world where we

Nobody wants to run browsers in the cloud. Too expensive. We really are getting the worst of all worlds with this, where we have to do all the expensive computations and all our subscriptions do is flip a flag in some database somewhere so

An immense amount of abuse is being done to "consumers" because most people don't have a mental model for how expensive subscriptions are and end up counting them as nearly free, because they are not even tomorrow's prob

It looks like it. My claim was not (and is not) that C# can't implement it, but that what is discussed in the post does not.
