My testing put the performance a bit shy of an A72 @ 2.4GHz. The U54 was on par with an A53.

I thought I saw someone else publish specmarks to corroborate this assertion, but i can't find it right now.

StarFive catalog parts use slightly tweaked SiFive cores. So if you were going to license a SiFive core for an embedded design, you may want to have something that uses the catalog part to verify your code will work.

I mean, emulating your core for development is a good approach in general, but at some point you may want to run your code on actual silicon.

So sure, an Intel i9 or ARM Mac is probably going to be faster than a 4 core U74 SoC, but if you're using a RISC-V core for some embedded application, having a RISC-V system to test with is probably a good idea.

And it's cool you can get a RISC-V SBC for a couple hundred bux. It wasn't too long ago that you paid $2k for a 4 core U54 SoC with minimal peripherals. And if you can stuff it in a laptop form factor, it's portable.

Did they mention how much this board will cost when it's released? The BeagleBone guys have a board based on the Micro-Semi / Micro-Chip PolarFire FPGA+U54x4 hard core for about $150, so I wouldn't think this one was too much more expensive than that.

SiFive's U74 cores aren't as inefficient as their earlier cores, but ops per megahertz still isn't on par with high end Intel or ARM cpus.

But if you're going for RISC-V, you're likely interested in it for something other than peak performance.

When I did my time in the RISC-V ecosystem, I thought we would never see catalog parts, so its good to see yet another RV64GC board using a catalog part.

I like the first title where you were looking for a software engineer with sanity deficit disorder. But I suspect the current one is better to find a decent partner.

I stopped flying United when they couldn't reliably carry me to/from destinations I frequented. But I certainly understand there /are/ people who do find United useful.

And I salute United's courageous strategy of annoying their customers. It's been a while since I've seen as clear a target for a short sale.

Spirit and Ryan Air, which already operate a rock-bottom fare structure, could get away with this. Those airlines have already identified customers who will trade annoyance for a lower fare. I had always thought of United as a "premium" brand. Clearly, United management does not see themselves that way.

I own stock in several companies. I would not want him anywhere near them. I have this weird desire to see them increase in value.

Because people have always paid to know what they really think.

I'm happy to see someone still doing some work in second life.

I wanted a dumbphone so I could avoid the crapware in android. But then I saw the Punkt MP01 with it's 4G hotspot and lust filled my heart.

So then I had a smartphone with android crapware and a very bad UI.

It did keep me from doomscrolling at the bus stop, so there is that.

I suspect the "iPhone of modern dumbphones" hasn't been invented yet. My gut feeling is there are about as many reasons people want to use dumbphones as there are people using dumbphones so getting "one dumbphone to rule them all" the same way the apple and Samsung have is a ways off.

BATCH, message facility, zero-headache clustering would be on my list. That stuff just works.

Is it time for an open source equivalent of VMS? Something that runs a rewrite of DCL and can compile and run C, Bliss and COBOL programs that make various LIB$ references?

Which is why it's weird the CCP is offering no regulatory love to a CPU developed and fabbed in mainland China.

I was sort of expecting at least one RISC V CPU to be on the list, but I guess we're still several years out from competing w/ Intel or ARM designs. And there's significant investment in MIPS toolchains, so maybe RV64 isn't quite ready for prime time in China?

And the music! I'm not a super Joan Baez fan, but I loved the two songs she did for the movie. And Schickele's score is awesome.

I keep calling it "A Dog and His Boy."

"if all you have is a nail, anything can be a hammer."

Rust isn't completely safe, it's just a lot safer than C.

And it's unsuited for many roles because it has eschewed reverse compatibility. Sure, you can write an operating system in Rust, but you'll have to re-write it (and possibly introduce new bugs) in five years or so.

I'm not the world's biggest C fan, but there are programs I wrote in the late 70s that still compile and do what you think they should do.

This whole post sounds scammy. There's no way to "call" PayPal. If the author would have said "spent two hours in a fruitless attempt to find a phone number on PayPal's web site," then I might have believed them.

But I can't figure out what the scam is here. Why make up a story like this? Maybe it's some weird way to train a 3rd party LLM? It finds some text on the internet and just includes it into its training set. Months later it barfs out sentences about "calling" PayPal? Seems like a lot of work.

Also, in the 90s we talked about tests as another indication of programmer intent. Since we couldn't get developers to document their code and "design as a practice" fell out of favor, tests were the only thing left indicating how the code was intended to be used.

The linked article is a bit wordy, but I think what he's trying to say is: write tests exercising the behavior of interfaces because you may want to change your implementation some day. The drawback of this approach is we don't have a universal way to express Bertrand-Russell-esque contracts on interfaces, so testing behavior when you provide "unsupported" inputs is rather ad hoc.

Looks like there's no love here for lefties. Pity.

I think we should nationalized Boeing, fix it and re-ipo it. Not because I think government can do better at operating at a profit, but because it would be a sick burn: your company was so poorly managed, it had to be taken over by the feds because an airplane version of Amtrak is a better alternative to letting the you clowns continue to manufacture aircraft.

Apropos the discussion of the warning lights, it sounds like there may be some human factors engineering issues as well.

It would be nice to get the black box data, but Alaska mishandled the box and allowed it to write over data from the flight in question. Oops.

I don't think the wing fell off the plane and there are several types of failures which are distressing short of the wing falling off.

"I would recommend that we put the unit back in operation and let it fail. It should then be a simple matter to track down the cause."

Sure, but grounding planes doesn't buy Alaska's (or Boeing's) CEO a new yacht. I suspect they will spend the minimum amount of time necessary, modulo whatever amount of time the IR and PR people think makes it appear they've accomplished something.

I don't think PR is an added bonus, I think it's the entire point.

The first thing I did when I encountered js in the 90s was write map and reduce. After leaving Mozilla I published a npm package with my hacks. I was very happy to find someone else had done a much better job at it and was actually maintaining it.

also, have you seen lazyjs? Also very cool.

There's a community that has experience doing analysis, design and coding with functional composition as an abnstraction. It's useful to reference that community so the viewer can get more information and more examples on applying it.

Also, sooner or later people will notice difficulties in communicating exceptional events up and down the chain and they would be greatly served by how Erlang/Elixir handles errors and process trees. Even if you want to stay in c# or f#, there's still wisdom to be gained by looking at how things work in functional languages and applying what you can in non functional languages.

Because The lisp community has been doing this for 50 years and has a different name for it.

People keep rediscovering and rensnming lisp features. I do think he's talking more about composition as a design concept, which is good for people who have only heard shout OO their entire career.

But yeah, it was weird hearing about this "new" idea I've been using for 30 years.

I worry that lazy evaluation will wind up as "filter based programming" next year.

But if it puts it in a form python or c# programmers can readily consume, it's probably okay.

Also nice to see someone doing something with f#.
