This is not the case. All 8 physical cores of the M1/2 can be utilized simultaneously, since each is a full physical core, independent of the others. The statement about only being able to use 4 at a time is true of threads, such as those found on SMT enabled processors that have core/thread counts like 4c/8t. In those systems, the threads share logic and decoding circuitry with each other, which would make your statement correct. You can see this in the M2 die shots. Both banks of 4 cores are in separate areas of the die. https://semianalysis.substack.com/p/apple-m2-die-shot-and-ar...

(edit): Granted 4 of the cores are lower powered "efficiency" cores, this is by no means equivalent to having just 4 cores

I think this is a thorough and interesting set of results. Others have commented on the spec differences (2x ram, 2x cores, whatever x power envelope), but I’m not as bothered by them despite being generally pro-Mac :)

I don’t think 2x ram matters in many (any?) of these, as for that to impact things you really do have to be using all the ram, and once you started doing that I would expect to see noticeable cratering in perf.

2x core count is more problematic, esp. for things that do max out threads, but many of these benchmarks clearly didn’t (or the M2 is insanely fast in specific tests :) ). Many of those benchmarks that do use thread count == core count allow you to cap the thread count independently which I would hope was done if possible.

Power envelope I just don’t really care about, if thermals force the laptop to throttle that doesn’t mean the performance numbers don’t match reality. I did go into this knowing it’s a desktop va laptop benchmark and know there will be trade offs involved.

I think it’s also worth doing a performance per dollar comparison here as well, though I have no idea what the result would be in this case.

So the hardware stuff out of the way, a few of the benchmarks showed such a massive performance delta (in both directions) that I wonder if we’re seeing code/codegen differences.

The reality is that the M2 is an arm system, and most projects have only ever really had x86 to worry about for performance, so they have “if x86 do vector stuff; else do it old skool one at a time”, which can have massive perf impact.

In the reverse I’ve seen code that goes arm==float32 x86==float64, which has obvious perf impact.

Anther huge killer is anything that uses long double. For everything other than x86 long double basically means float32 or float64. On x86 (everywhere I think except win64?) long double is float80, which is much much slower than the alternatives for far to many reasons to list. So that seems like it could easily footgun code that’s being benchmarked as well.

All in all I thought this was a good article and it was an interesting read.

Defamation is criminal in some places, and you have a right to cross examine accusers wrt civil infractions anyway. Maybe that bar doesn't get met in this case, but TFA was pretty clear that the alleged issues aren't just not attending a conference.
To be honest, this has much more to do with Randall Stewart's RACK TCP, and his team's obsession with improving our member's QoE.

Most people want a search engine designed to understand what they want in context.

But until people pay for that search capability directly, the economic incentives will not align.

And there is the ever present temptation of accepting money from advertisers. This is potentially lucrative. Will consumers ever pay enough directly to offset seller interests to sway search results? I doubt it under the current regulatory framework.

We need changes.

Some people (policy people and economists mostly) know about Ronald Coase. One of his key points is we can rebalance who has the upper hand at the beginning of a market (initial conditions) and still have economic efficiency.

Coase's classic analysis compares two hypothetical worlds. In one world, smoking is legal and non-smokers have to compensate smokers in order to have a smoke free experience. In the other world the opposite is true. Both worlds can be completely economically efficient (defined as the equilibrium where there are no additional exchanges that make all parties better off). The difference between the worlds is purely distributional --
who gets to have more money.

Distributional questions have a considerable ethical component. Like most people, I prefer the second over the first.

Regulation could also similarly apply to search engines. We could tilt the balance in favor of consumers instead of sellers (in the case of public companies, this means investors).

What am I proposing? Simply put: more discussion about such options.

I will not try specify the best legislation for all situations in this already long comment. This does not mean no significant improvements are possible nor feasible. I simply do not want to get mired in debate over only one policy option.

About me: I listen to good libertarian style arguments as long as they are realistic about the standard economic model's limitations and failure modes: externalities, market power, imperfect information, nonrational consumers, and so on. / I lean liberal, so I care about transition costs too. Rapid change is hard because people have limited geographic mobility, especially in the short run. I also care about observable, measurable opportunities more than only hypothetical talk about options.

Usually this is because the repo is private (rather than because it doesn't exist).

Sometimes this is a genuine mistake: people may use a private repo because they're concerned about a competing researcher seeing their work and scooping them, and intend to make it public once their paper has been accepted but forget.
What are you talking about the most controversy is that scientist are refusing to answer questions sceptics have. Your talking points are just well poison used to make critiques look stupid. Like what is the margin of error of the climate data. They don't give any and just say they don't need too, they are perfect. Which can easily be disproven.
Even Bill Gates criticized that scientist don't have an answer to "cloud formations" in his TED Talk about climate change. Clouds just don't exist in climate models, because apparently it's just to complicated.

Opened the documentation link, clicked on the ‘Open Demo App’ and decided to return to the documentation link page. The back button on my browser doesn’t work. I’m stuck on the demo app page even though I haven’t activated/entered the App. It could be this is caused by my iPad itself. If not, it’s not good when a site ‘hijacks’ your browser back button and prevents you from leaving a page.
But it’s still a fair comparison in that this is the performance you will get.

I love the syntax of SML and found the examples of it I've seen online to "click" for me, which isn't the case with OCaml (ugly syntax) and Haskell (can't read it).

Always was a bummer that SML was a sort of dead-end language without a good tooling story.
On iOS at least there are more restrictions of using SafariViewController vs WebView. I could imagine Apple making a policy change to force towards that stricter surface.

They are far more safe than cars, and hence they should remain allowed until cars are banned.

Interesting thought, but every evangelist of TDD that I’ve met has nothing to gain other than wanting the code in production to be cheaper to write, more maintainable, proven to work, faster to market, the list goes on. They often care more about the business and the costs involved in software development and are usually pretty selfless.

All of these are well known carcinogens but it is crazy the lengths people will go to defend alcohol especially in this regard. Alcohol, in any amount, is a poison and is treated as so by the body. It breaks down into acetaldehyde and damages DNA.

I'm all for people making informed decisions on what they want to put into their bodies but informed is the operative word. There's a reason people don't associate drinking or being fat with cancer the way they do with cigarettes.

> AMD and Intel chips usually max out at around 50-60w real-world power.

That's a sweepingly broad claim that's not at all well supported. AMD & Intel both make CPUs that top out far below 50-60w real-world power and also top out far, far above 50-60W real-world power.

From a different review of the same CPU (didn't check if same laptop, could be though)
"The Ryzen 7 PRO 6850U with the Linux 5.18 kernel had a 18.4 Watt average (or 16.6 Watt average with Linux 5.19 Git) while the Ryzen 7 PRO 5850U average on Linux 5.18 was up at 21.96 Watts."
https://www.phoronix.com/review/amd-ryzen7-6850u/8

So no, this isn't a 50-60W real-world power CPU. That's the non-U SKUs.

But if this AMD was a 50-60W CPU that'd exactly prove my point that TDP is a stupid number to compare and you always, always have to look at actual power consumption used (which this M2 vs. 6850U didn't do because as noted briefly in the intro power monitoring of the M2 doesn't work on Asahi yet)
Depends on where you are.

In the company I used to work at, code quality was a huge deal. I think, destructively so.

Nevertheless, I exercise pretty extreme code quality in my work (see for yourself[0]). It's long reached the state of "muscle memory," and I work very quickly.

As I am the person that most frequently has to go back and fix the code I write (I eat my own dog food), I write code that is what I want to see, when revisiting, six months later.

On another note, this industry considers six years to be "senior." I find that interesting.

I suppose this comes as no surprise. It almost feels like a conspiracy that With the exception of a few illegal drugs such as meth, heroin and cocaine, the only legal drugs are the ones that arguably carry fairly high risks. Though I suppose the damage from smoking comes mostly from combustion and not the nicotine.

High BMI is such a problem in the west and so trivially preventable. I have family in both medicine and the school system and the number of children who are morbidly obese seems to get higher every year. One thing I've done to pass the time is to count the number of obese people where ever I am. It's relatively shocking that within some margin of error the vast majority of people appear to be obese. Pairing this with the social contagion of "Healthy at Any Size" and we quite possibly have an epidemic worse than anything we have ever seen before. More than just cancer, obesity is expected to surpass heavy alcohol abuse as the #1 cause of severe liver damage.

I am surprised however that chemicals in food weren't studied as a sub-group of the BMI study. Endocrine disrupters are basically everywhere now. A standard western diet is so loaded with garbage.
A possible counter model to this kind of organization is how the Nicolas Bourbaki collective organized their work:

"Subcommittees are assigned to write drafts on specific material, and the drafts are later presented, vigorously debated, and re-drafted at the conferences. Unanimous agreement is required before any material is deemed acceptable for publication. A given piece of material may require six or more drafts over a period of several years, and some drafts are never developed into completed work. Bourbaki's writing process has therefore been described as "Sisyphean". Although the method is slow, it yields a final product which satisfies the group's standards for mathematical rigour, one of Bourbaki's main priorities in the treatise."

It's also interesting that the maximum power consumption eked out of the Ryzen 7 Pro 6850U was a touch under 32W. Where did this 46W number of the parent comment come from? Or the 50-60W in the comment below? They must be thinking of a different CPU/APU.

It's certainly what Cloudflare found when they were evaluating early ARM server chips.

>the first benchmark would be the popular zlib library. At Cloudflare we use an improved version of the library, optimized for 64-bit Intel processors, and although it is written mostly in C, it does use some Intel specific intrinsics. Comparing this optimized version to the generic zlib library wouldn’t be fair. Not to worry, with little effort I adapted the library to work very well on the ARMv8 architecture, with the use of NEON and CRC32 intrinsics. In the process it is twice as fast as the generic library for some files.

Very cool to identify that "autism" is genetic. But I'm certain that there is no such thing as "autism" but a varying set of disorders with vaguely similar symptoms.

So there could be one kind of autism that is 100% genetic and the rest are 0% genetic. But we don't know, because we are still lumping them together.

Fair enough, but often consumers that use multiple vendors receive webhooks in the same service; think about going from /v1/webhooks -> /v2/webhooks, they'd have to change the URL for every vendor. Easier to redirect first then update the URLs later. I think it's a reasonable expectation that a HTTP client would honor redirects as long as the usage isn't malicious (like loops etc)

I would think the real difference this time is the existence of the iPhone and iPad markets to help scale the costs of Apple Silicon development.

When Apple was using PowerPC the number of PowerPC units shipped was tiny compared to the PC market.

The huge volumes of mobile devices that Apple now ship has got to at least help share R&D costs across product lines.
