I have an original, real Altair 8800. They aren't super solidly built (lots of individual wires), and having been sold as kits, the assembly quality on them is very variable. Among the many tens of vintage computers I own, the Altair is definitely the most finicky to keep running.

If you're interested in understanding what it was like to use an Altair 8800, the software available for it, etc., this is a great way to go. I've been really tempted to get one myself.
We think open source is important, of course, because it has cost and control ramifications, but I'll stay focused.

Stitch looks to be doing ELT in the fivetran-ish space. Their "sources" are lots of tools and their "destinations" are warehouses. Grouparoo can have sources like Mailchimp (did they read the mail), but Mailchimp is more likely to be a "destination" for us.

This is because we are doing more like ETL to those tools. In our current case, the "T" is property and segmentation definitions, often done by end users like marketers. So that notes that our users also include non-engineers. There's less burden on engineers after setting up Grouparoo because the person in charge of Mailchimp are doing those definitions.
Haven't you seen ghostbusters? "Don't cross the streams. It would be bad." If your data model has lines crossing over, it's the first smell of a bad design.

Isn't JQ written in C? I doubt LISP is going to be faster.
This is too bold a claim. Not an inaccurate one, as with some languages runtime does play a huge factor in widespread adoption, but as with many things, it's just more complicated than that. Obviously scripting languages like python do not depend on runtime for popularity, except when they do. How can you even separate Go's syntax and paradigms from its runtime when it's defining attributes (parallelism) are so tightly coupled to it?

I don't really disagree with any of the overarching points here, other than the supposition that "runtime" is anywhere close to the one factor to rule them all. Adoption is determined by....mostly adoption. You generally choose the most popular language that fits your needs, however stringent they might be, and initial adoption has so many factors that go into it, and if syntax and paradigms were irrelevant, then why would C++ have superseded C, only to be replaced itself by a variety of languages addressing a variety of needs?

It's just a PIC with a hand-rolled clock-accurate emulation of the 8080 and the supporting circuitry. That's not a small amount of effort.

So far as I know the 8080 has been EOLd, so it would be hard to source it today anyway.
Unless you're building something on your own, in which case there is an (unoffically supported) attribute which you can use to opt-in to swizzling of methods. The difference being you have to opt-in, so you can't swizzle someone else's methods (unless they let you).

You can still find new replica CPU, RAM, and probably backplane boards out there for sale, so if you wanted to build your own replica, it's not impossible. Figuring out the case and the front panel would be the hard part, I think.
Most of those problems could be avoided by using higher refresh rate. 120+Hz is pretty common in gaming and phones.

(It should be clear, but this is both factual and a joke. The core team is good people, Slava is good people, Slava is not on the core team.)
Great article. The brute force solution to this problem is switching to high refresh rate monitors, but if you want to beat Apple II latency by brute force without fixing the underlying issues in modern software then 120 Hz probably isn't enough. You need crazy high refresh rates like 240 or 360 Hz. I do enjoy high refresh rates, but they are not great for power consumption and limit the resolution you can support.

> I would assume that this has the same debug issues as omitting the stack trace.

I don't expect so. If I "forget to handle" an optional, I get an error at compile time pointing at the lines in question. If I forget to handle an exception with an omitted stack trace, IIUC, I am told at runtime that there's an error somewhere in my program. It's much easier to debug the former.

It's baffling. Like you said, GM will use its own technology. So they bought 11% of Nikola for…edgy CEO shitposting on Twitter?

GM can definitely build a good electric vehicle. They cannot seem to market a good electric vehicle—see Chevrolet Bolt sales, and then ask a random person if they know what a Bolt is. So the Nikola investment is the equivalent of buying a hip design studio?

>No. The scientific method is the foundation of science

Simple question then, which aspect of the scientific method is not compatible with "human law?" I can develop a question about how society works, form a hypothesis, develop experiments, and analyze the results.

I may develop poor experiments and as a result only be able to provide limited analysis permanently tainted by a "human law" bias, but it would still be science.

I am by no means an expert in graphics architectures so I'm sure someone will be able to explain this better and more correctly than I can. But as I understand it, "native" is itself a layered stack of APIs as you can see in this diagram:

https://developer.apple.com/library/archive/documentation/Co...

UIKit/AppKit is layered on top of Core Animation which is layered on top of Metal. Skia, the 2D graphics library that Chrome's rendering engine uses, is built on top of Metal (or at least transitioning to Metal from OpenGL on macOS).

So browsers have the same flexibility in principle as native UI toolkits and they are just as close to the metal. There is no inherent disadvantage. But flexibility is a double edged sword. It includes the ability to diverge from the platform look & feel. So that's where the debate has been raging on for decades.

In terms of performance I think any debate about optimisation of UI stacks pales in comparison to the question of where the data lives, who generates it, and how it gets to the CPU/GPU for processing and display.
Public libraries. It may sound funny but I’ve seen multiple posts on reddit forgetting they exist. They may be under some weird covid restrictions at the moment, but they’re very beneficial. Also, don’t buy hardcover, just wait for paperback. You’ll treat them like actual books, they’ll take up less space. Win win
Although all organizations are influenced by their particular constituency, the guys at 80k have been led to these causes by particular philosophical and empirical arguments, which they explain in the website at great length, not (say) because they all used to be ML researchers. (They do not have technical backgrounds.) You can certainly disagree with the arguments, and they would be first to agree that their conclusions (although not premises) are radical.

But more importantly, I think if you just went and talked to random political scientists, you would find they actually had not thought very hard about what the most important causes are. If you ask them, they would come up with something on the spot. Indeed, political scientists don't at all seem to be the correct experts for this question.
> It seems a bit reckless to assume that ANY AND EVERY high-tech alien civilization would produce conclusive evidence on a scale such that any civilization like modern humanity around any given star would be able to detect it.

"ANY AND EVERY" is not remotely a part of any plausible premise of either the Great Filter or the Fermi paradox. Please be charitable in stating assumptions of theories you disagree with.
> Turns out, the type system they built guarantees 100% that type checking is undecidable

Someone found this in Java as well. Accidental Turing completeness crops up everywhere, it's actually rather hard to ensure decidability. It's a favorite pastime of people in this area; I'm somewhat disappointed you didn't find it to be interesting. In any case, personal attacks against the Swift compiler engineers (many who are quite competent at the things you are claiming they are lacking) are not appropriate.
Does HN have higher standards? Maybe different standards, but I don't know that when it comes to reading the article that HN is much better than Reddit.

I have been playing with the idea that a rule engine would work well with a state machine.

State machine manages the workflow, rule engine determines which transitions to execute?

Maybe that is overkill, but I've been trying to build a model in my head on how to model complex business processes.
It's interesting, but the conditions on Venus are of such high pressure (93 bar) and temperature is so high, that using the fact that phosphine does not appear naturally on earth (by that I mean by non biological means) doesn't mean there is a biological process. Venus is quite a different beast as environments go.

There could be a relatively simple process at high pressure/temperature that produces it in abundance (it's not a complex molecule).

My point is that until we have evidence of an actual organism, we cannot jump and say "life created this".

I agree with the "room for new people" conundrum but you could approach that as a population control issue from a couple of different directions.

Or you could approach lifespan extension simultaneously with research on its consequences, like how to structure society (economics, politics, etc) so as to optimize well-being.

Overall, we believe events are an overused approach in this space. They clearly have their place for impression data, but product dbs or data warehouses have lots of good stuff that isn't being used enough to drive goals.

I'm curious as to whether we'll ever have wind/ocean current energy capture that's sufficient to disturb things enough to cause detrimental (or maybe beneficial) effects.

Supposedly, the recent - apparent - changes in UK climate are due to changes in trade winds through global climate change. There might be small perturbations that we make that inadvertently make for large changes in major wind/current systems?

I'd guess someone has tried to model these things.
Indeed it was. The thing that made it special was that it used the same backplane and board dimensions, making it completely compatible.
> we should keep numeric data in “integer”, “numeric” fields

Hey! I wrote the post.

SAFEs make it easy these days to add someone to the round (for any amount). The issue becomes time management (is it really worth hours of calls, responding to questions over email, etc) trying to close such a small check.

There's a secondary issue of wrangling each investor in subsequent rounds or an acquisition (which that can just gets kicked down the road). Some investors provide value beyond their money, mostly with their connections to other investors, connections to potential customers, and skills in certain areas, or just generally someone you can call for advice.

One thing I've learned having gone thru this process: it's common for angel investors to write small checks, though not common knowledge. I always thought you needed to write a $25-50k check to be able to invest in a startup. It's common for people in the industry to invest smaller amounts like $5k-$10k, sometimes even less than $5k. I've even now started doing it myself.

Facts I looked up to understand this comment:

* Bias in a bit-stream means any deviation from IID Bernoulli trials with p=0.5

* Von Neumann whitening addresses the IID Bernoulli case for p!=0.5 by looking at bit pairs. It takes the first bit when they differ, and no bits when they match. This works because (1,0) and (0,1) both occur with equal probability p(1-p).

* NIST wrote a remarkably accessible document [1]

What is the alternative. If your goal is for RISC-V to be universal you have to support lots of things.

RISC-V strategy make sense, first standise the core that allows you to run all tooling. At necessary thigns like floats and so on. And the move on into more interesting extentions like Vectors.

If a company does something unique, the can take the standard compiler and have standard way to add an extra extention.

Of courese because the world is not perfect you will have some sudo standards and companies that have their own version of some of these.

Profiles is a way to manage that and to find configuration of extentions that often work together for desktop, embeeded or something like that. Seem relativivly well thought out for something that has such braod application.
Some people do not know that they are subject matter 'experts'; as they typically have to have respected colleagues state this. My wife and myself are examples - I have told her for years that there is almost no one else at her level, but she dismissed my claims until well known (in their fields) professors started to call her frequently for advice and ideas.

I considered myself competent in some stuff, but never an 'expert'. About 10 years past, peoples in various IEEE societies prodded me to publish stuff and do talks at some of the respective annual symposiums. I still do not consider myself an expert - because I do know some actual experts in some of my professional fields and endeavors, but there are other engineers that do rank me as such, which I have accepted because it gets me more work.

My wife became an expert by solving some difficult problems. She solved these seemingly intractable problems by deep observations, knowing what questions to ask, and knowing whom to ask questions.

I have increased my professional competence by education (both formal and self-taught) and carefully choosing companies and problems to solve. But I am too general of a practitioner to be considered an 'expert'.

Damn straight. A short seller with compromising info has all the incentives to broadcast it, then sit back and look how he makes money. He injects valuable information into the market and puts his neck on the line - since the downside of a short position is unlimited. No such incentives exist for long holders.

The problem are never short-sellers per se, bur rather the fabrications some diseminate to induce panics. Those guys that try to manipulate the market with false information should be vilified, not short sellers in general.
