32 bit RISC-V code density is slightly worse than Thumb2, but better than any other 32 bit ISA I'm aware of with similar performance. I don't know much about AVR32 except that it is very dead. Some ISAs designed explicitly for microcontroller use have denser code than RISC-V and Thumb2 on things such as manipulating GPIOs, but not on algorithmic code which makes up the vast majority of any application over a few KB in size.

64 bit RISC-V code density is far better than 64 bit ARM code density, which is similar to AMD64 (i.e. quite a bit bigger than i386)

Other than a few extra instructions to zero-extend 32 bit values to 64 bits at times, 64 bit RISC-V and 32 bit RISC-V code are identical in size.

High performance general computing these days means 64 bit, and RISC-V has by far the highest code density of any 64 bit ISA.
It's great to see things all coming together but this part made me chuckle:

> officials declined to say whether this first SLS launch will occur by year's end as had been planned or will bump into 2022

SLS was meant to fly in 2018. It's clear there's something very wrong with the NASA/Boeing/Lockheed combination. These companies have perfected the art of milking the taxpayer and impeding advances like orbital refuelling and depots as much as possible for the sake of higher profitability.

There's been over ten years of prominent people and ex-NASA administrators calling for it to be scrapped, these people have proven right time and time again, because now it's a $20bn white elephant with little future and everyone just going through the motions until it is shuttered.

NASA just signed a new contract for the already developed single use RS-25 engines on SLS, they are paying $150m per engine. This is about the same cost as a fully resuable Starship by SpaceX.

I bought one of these and sent in the kit. I never got the results, they said there was a technical glitch IIRC and I needed to do it again, but everything up until that point was really well done. This was probably 2016-2017.

I have no other details, other than I don’t think the alleged crimes committed by them or Theranos are nearly as bad as the ones committed by big pharma and uspto and the rest of the healthcare industry. The whole thing is an f’ing sad joke. So I guess my $200 for the ubiome went down the tube, but what about the $1,800 that HMSA just tried to bill me for going to the doctor for a COVID test last February? How about the 500,000 lives lost to the opioid epidemic? Are any feds investigating USPTO, who was Purdue’s partner in crime? Nah, don’t think so. Let’s go after some small fish in the pond instead.

I blame the 30 something entrepreneurs who grew up in this toxic space a lot less than the 60 year old healthcare execs and government officials who created our f’d up system that we are all suffering from.

If you want to avoid the mistakes of both Theranos, uBiome, and big pharma here's the key strategy: avoid secrecy and #imaginaryProperty at all costs. It puts the patients last and is bad for the world.

"99.9%" is usually what you see when people are talking about the numbers of people in their whole population who haven't died from it yet. I appreciate the problems in test data when talking about case-mortality, but population-mortality is utter nonsense.

Not to mention that in many places the whole population-mortality is now more than 0.1%. 0.2% of the UK has died from Covid. A few places are worse than that, and many places are on a trajectory for 1% if they can't control it.

My friend and I were obsessed with C&C RA in the late 90s. This was the first "multiplayer" game I really played. We would play over the dial up modem, but both of us had only one phone line so it was frequent that we would lose the game connection because of sisters who would pick up the phone and yell in to it to break our connection.

It was a remarkable game. It's incredible to see how for OpenRA has come!

If somebody does an open source C&C Generals (that runs on Linux), I'd be in heaven.

Well purchasing an NFT doesn't really reallocate any resources that would have gone to those things, so I don't think it's a huge issue. They are just transferring money from one person to another, essentially.
Right - that's what triggered my comment - but I think it's a bigger footgun than the article does. The problem is this corner case opens up all the fundamental issues I mention. When we include it we've got a big non-deterministic, racey, stateful, problem.
> mypy is the static type checker that is the most popular (28.3k repositories, 1.9k packages), if you are using other type checkers then congrats, you will just be the CoffeeScript/Reason user of the JS world, refusing to believe that TypeScript won the mindshare

Not really. TypeScript is a JS superset (and TypeScript tooling works with unadorned JS, too), but Coffee script/Reason are incompatible languages that happen to compile to JS and have static typing. All of the Python typecheckers are more like TypeScript, except that even the type annotations and much of the type system is also standardized as part of the core language. You can literally use any of them on the same code base, and get largely the same results (some will catch some type errors that others miss, some will flag some correct code as possibly erroneous that others would leave alone, but the differences tend to be minor.)
Also, if a group with money generally agrees about (and demonstrates by buying) the desirability of something, it becomes just as valuable to people outside the group. I don't have to care about NFTs to buy one that I know I can unload.

The problem comes when the auctions start failing i.e. people who bought NFTs with leverage can't sell for enough where they won't be wiped out.

The art market runs on the self-image of wealthy people as superior people, which requires constant critical appraisal and reappraisal by designated experts. There's no chance that the ability to piss money away on an acknowledgement in a distributed ledger can compete indefinitely with the ability to piss money away on a canvas by a dead abstract expressionist painted in their own piss and shit. Academics and famous aesthetes will call you a genius for owning the second. How long are you going to be able to brag about one of these, and who to?

Every initial transaction with these is giving some real person real money for absolutely nothing in return. Who are going to be the designated issuers, and why? Who is going to pay for Scott Baio's Designated Cool Dude NFT, and how much?
I wish I could say. I haven't spent much time looking into other options.

Sure, whales cannot have "culture" if we define it as "art, morals, laws" etc, by definition.

But we also need a word for a shared, passed-down learned experiences.

Such a thing has been observed in numerous species. For example, certain groups of gulls have learned to drop shells onto the rocks to smash them open. Similar gulls in other areas have not learned this. The ones that have have passed this lesson down for generations.

"Culture" to me sounds like a perfectly-good word for it. Cambridge Dictionary has the definition "the way of life of a particular people, esp. as shown in their ordinary behavior and habits."

Words can have multiple meanings in different contexts.
<grin>

That's a bit like my 8080 disassembler in COBOL, back in the 80s.
NFTs are a mechanism for transferring money from rich people to artists who are not rich. Isn't this something you should support, given your stated beliefs?
The only case I witnessed where the interface remained untouched, even as we went from an rdmbs backend to kvo and back again, was Twitter. You can argue the reason is the data model being simple, which makes sense. Everywhere else, it was different degrees of “pain”. I don’t think there’s a silver bullet, and I don’t think avoiding a potential future rewrite at all cost are worthwhile goals.

WRT sqlite, the obvious advantage is test setup doesn’t require any local infra, and it forces your system to NOT use vendor-specific features. That school of design is essential for places that want to avoid lockin for whatever reason. This isn’t possible in every case - some companies have a great DBA team, for instance, or strong specialization around a specific db (cough Oracle shops cough), so obviously that flexibility wouldn’t be advantageous. As everything else in our industry, it depends :)

Remember the context. We were staring down mass casualties due to dramatically greater need for ventilators than available supply. Something that maybe kinda worked a little bit 1 in 100 times could have preserved a lot of life. We got away with being picky because the situation got intercepted by other mechanisms before becoming that desperate.

Your original example is very specific, but your follow up clarifies that the reality is that it is vague guesswork. I think you could claim contribution, but very hard to define that line x of code written last Friday resulted directly in y% of profits.

To me it signals you're probably exaggerating. You better be able to back up your reasoning behind your claim. Bold claims require bold explanations.

You do not understand me. Reactions to an order make sense. But if I click "Buy", and before the order hits the book, the software vendor that is processing my order notifies a market maker to increase their price in order to make me pay slightly more, this would be unfair ("front running").
Larger models aren't really more complicated than smaller ones though. GPT-2 is already supported, I believe only difference with GPT-3 is sparse attention.
> Why not just adopt one into the standard library, seems like a very obvious battery you'd want to include.

Instead, the approach seems to be adopting a standardized system of type annotations into the standard library. While a typechecker may expose a library interface, it's main use is as an executable tool, not a library (unlike annotations themselves), so it's not super critical to have one in the standard library. It might be convenient to have it in the standard distribution, but as a practical matter it's not like there is a problem getting at least one of them that does a suitable job with standard type annotations anywhere you can get Python.
Like I said depends on the company.

This is like describing a baseball card as a low-quality reproduction on cheap cardstock of an original photo.

Personally, I don't care for baseball cards, I value them about as much as the paper they're printed on. But collectors like them, so if I found one (I dunno, dropped in its sleeve into a tip jar?), I'd check if someone else wanted to pay for it before I started using it as a bookmark.

Same deal with NFTs. The difference is they're brand-new and white-hot, and it remains to be seen if they have enduring value.

My guess: NFTs will continue to be valued, but the vast majority of those which exist right now (and of every NFT ever minted) will be worth so little that it isn't worth the transaction fee to transfer ownership.

The John Cleese Brooklyn Bridge though? It's a great joke! Might not be worth whatever it goes for down the road, but it will probably still be worth something.
Apple and Huawei were typically TSMC’s biggest customers and both those companies have been on the bleeding edge driving process technology (typically adopting the new node 1 year before everyone else). With the Huawei ban, it’s unclear if their absence as a TSMC customer will affect 3nm.

I don’t see AMD having a broad enough portfolio or deep enough pockets to chase the leading edge nodes in the same as Apple and Huawei.

I can likewise draft a theory that media is pushing a narrative of 'the lockdowns are unnecessary, your government is cheating you' in order to stir up controversy and get clicks.

Both your, and my theories hav little predictive or explanatory power.

And if we're dealing with anecdotes, I can also cite that I know people who were not afraid to be going to crowded bars (Check out central California, if you want to see people flouting lockdown, and spending their stimulus checks on partying in, say, Modesto) over the past ~year, despite not being vaccinated. Do you think those people may have been influenced by the media pushing a narrative that lockdowns are unnecessary?

Here's the actual answer to this dilemma. 'The media' is pushing both narratives. You are just paying more attention to one of them, because that's the one you happen to disagree with. There are very few issues where 'the media' boogieman presents a unified front, and COVID-19 has not been one of them.

In this particular case, the way the site semi-periodically twitches is kind of interesting itself. Way more than the common annoyances that you rightly chastise people for complaining about.

1. There are no apparent ads on the site. There are three things uBlock origin blocks, but they don't seem to be things doing anything visible (I'd guess trackers).

Usually it is sites infested with ads and a ton of trackers where you encounter visual glitches this jarring.

2. The interval between glitches varies, and sometimes it is a double glitch instead of a single glitch.

3. If I open the site in both Firefox and Chrome, their glitches are in sync. Same if I open it in more than one Firefox or Chrome window.

This suggests whatever it is doing is based on clock time, not on time since page load which is what I would have expected.

4. The glitches are much less frequent in Safari.

You don't even know how valuable this is to me at this exact moment in time.

My first interview is tomorrow night! Fortunately, it is with a friend and co-worker who has the hacker mindset and will be willing to work through hiccups in technology.

I'm trying to pick a video conference platform to try. Do I discord? Zoom? Try to find a way to set up audio line-in from my android phone.

I need a solution for tomorrow night so the blog post has found me at exactly the right time.

Thank you.

Edit: having read the blog, I thought that free zoom ended after 45 minutes! I didn't realize that one on one would allow longer sessions. Great!

The best part of zoom from my point of view is that people don't have to log in to anything to join me on a call.

If I wanted to use discord for example if have to make my guests install it or make an account there. I'm pretty sure that some of the big-time grizzled greybeards I know would probably sooner pull out of the interview than sign up for a new service.

And they're some of the ones that I'm most interested in hearing from.

> IMO if we’re going to have minimum wage in the US then we need to make it work for its intended purpose of requiring companies to pay people a living wage for their labor.

The best answer to this is that we shouldn't have a federal minimum wage.

Minimum wage is one of the depression era policies like price controls that were instituted before we knew better. It is a price control.

The reason we still have it is politics. Notice that the advocates of raising the federal minimum wage are overwhelmingly from states that already have a state minimum wage above the federal one, and could set their state's minimum wage to anything higher as they like, since it's a floor, not a ceiling. So why do they care?

They care because the cost of living is different in different regions. $7.25 might be a living wage in El Paso while $15 might not be in San Francisco. But California doesn't want their tax base moving to Texas, so politicians from California want federal laws that make it more expensive to do business in Texas. They want to deprive lower cost of living areas of their competitive advantage.

You can tell something is fishy when most of the supporters of raising the federal minimum wage represent zero people who actually make federal minimum wage, and the representatives of the people who do make federal minimum wage are the opponents.

And actually instituting the policy screws over the people it's supposed to be helping, because then the jobs stay in higher cost of living areas and the higher cost of living causes more harm than the lower wage would have in the lower cost of living area.
HR doesn’t work for you, the fact that you’ve witnessed a few random cases where they helped coworkers doesn’t change that.
