Careful with the word "unlamination", since it is usually referring to a different thing than the usual splitting up of micro-fused ops at execution.

As far as micro-fusion, there are at at least three interesting possibilities for the uops originating from the same instruction (with a memory operand):

1) No micro-fusion at all, e.g., for shrx and friends. The number of fused domain and unfused domain uops is the same.

2) Fusion in the uop cache (and probably the IDQ), but not the RAT and later stages. This is a case where the instructions are fused at decode, but are "unlaminated" before rename, and hence it usually has similar performance to no fusion at all (but it does save space in the uop cache), since RAT is more likely to be a performance limitation. If you look at the performance counters to determine fusion, this will look like case (1) (unless you check the DSB uops delivered one, I guess).

3) Full micro-fusion. This is the "normal" micro-fusion that people usually talk about: fusion persists through the RAT and get split up for execution.

As far as I know, "unlamination" refers to the process that distinguishes between type (2) and type (3) - the former are unlaminated and the latter aren't. The existence of type (2) isn't even really clear from the classic sources like Agner's doc, and the behavior has changed even on recent archs (e.g., Skylake unlaminates less scnearios than Haswell).

All the gory details are here:

https://stackoverflow.com/q/26046634/149138

About RMW ops, it usually ends up as 4 unfused uops (store data, store AGU, load, ALU) which get fused into two micro-fused pairs (the store, and the load-ALU) op, not fully fused into one uop. The same concerns about type (2) vs type (3) likely apply also, although I haven't tested it.
My work machine is a 2017 MBP; previously a 2013 one, and before that 2008 or so. For my usecase (programmer), it’s so much better than the 2008 one it’s not even funny, and also substantially better than the 2013 one (in particular, the SSD is much faster, and the battery holds up better for me). I’m a professional user. I’m not really seeing the problem (for my usecase).

Edit: Also, I know people love to complain about how thin it’s gotten, but as someone who has to drag it to meetings a lot, I kind of appreciate the thinness (along with the one-port connection when I get it back to the desk).
> ...it was devastatingly clear that I had completely wasted on average 20-30 hours every week for the past 10 years of my life, hours I could have spent making friends and/or becoming a normal person.

Beyond the "making friends and/or becoming a normal person" issues, don't you think that training for 10 years on a single goal gives you an idea of complexity that you can apply to other fields? I was (90%) healthy obsessed by developing software in my youth and that gave me an edge on how far, now, I can help others to solve software development problems.

I used to do this 15-20 years ago, ran my own smtp server too, dropped thing via spamassasin, custom email aliases for each sign up, etc etc.

The life got too short. Pine was ok for simple emails, but HTML mails and attachments meant moving to a graphical system. Wanting access to mail on the go meant squirrelmail which was inferior to most web mail. Then along came smart phones and I was having to run imap on my server too.

I suspect nowadays any emails I sent from my anti server would be scored highly for spam flagging too.

In the end I just used gmail. I can count on one hand the number of spams I get each year.

I believe newer Python versions have at least deterministic iteration order (correct me if I'm wrong), while some previous ones had a non-deterministic one (non-deterministic between mutiple invocations of the interpreter). But there is also OrderedDict which iterates in assignment order.

> If that's the only thing keeping the will "free" would it even matter if our decisions are made deterministically or by a dice roll?

This is a good point, and relates directly to the paradox I see.

It's not that randomness is required for free will, or even desired, it's that all other known processes are deterministic. It's an age-old discussion that if the state of the universe and all the particles in it at any given moment is determined entirely by physical laws like conservation of energy, then, it is theorized, free will cannot exist because the future state of the universe can be predicted.

We may have the appearance of free will, but if our thoughts emerge from predictable phenomena, then autonomy and consciousness as we know it can only be a facade.

Quantum randomness is the only process we know of that can't be predicted by a sufficiently powerful simulation. Therefore, quantum randomness is what some people rely on to posit the existence of free will, only because it's the only thing left by process of elimination.

Your point is similar to my question, namely that even if there is randomness, we still have a problem. What's willful about an unpredictably chance event?
> a) 85th percentile will keep creeping up with each iteration of such speed limit adjustment,

That doesn't actually occur. In 1997, West Virginia raised its speed limits from 55 to 65 mph on limited access 4 lane divided highways. The 85th percentile speed incrased from 62 mph to 66.5 mph. The compliance level with the speed limit went from 15% to nearly 85%. On interstate highways, the speed limit increased from 65 mph to 70 mph. The 85th percentile speed increased from 70 mph to 71.6 mph. The compliance rate went from 50% to about 70%.

In both cases, the compliance rate went up (in one case, substantially). Also, the Martin Parker study [1] also says that lowering and raising speed limits do not substantially affect actual traffic speeds.

This is exclusively the failure of right-wing politics and corporation-first, profit-first thinking. The US could operate its full budget without a deficit if it just taxed corporations at a reasonable rate and didn't accept bribes/strong lobbyist behaviour to change laws and create loopholes.

Yes, the Trump administration is at fault for the recent jump - but they are merely adding to a problem going back decades.

Apple should pay a lot more tax to the US than it does. So should Google, so should Exxon, etc. So should all the rich people in the USA.

Time and time again, right-wing people will argue that the corporations and the billionaires will flee the USA if we keep their taxes the same, or increase them some. But that's just not true. In fact, the corporations will flock to the USA and so will the billionaires if you raise taxes on them.

How do I know this? Because it's the only logical thing. Corporations like stability because it makes their profits predictable and lets them control the mood in the room (innovation, regulation, etc). Low taxes for the rich mean chaos - an extremely large, underpaid, underfed, underrepresented bottom class will not be good for the rich in the long run. High taxes for the rich mean a well-sustained middle class, with money to spend on products made by the corporations. It is also a safer place, with less homelessness, less violence, less hatred.

Raise the taxes on the rich. Stop the false narratives perpetrated by the hate-driven, xenophobic, spiteful right-wing media. Raise taxes on the rich and our society will be so much better for it - especially the rich.

What I really don't understand is why these (my) opinions are considered left-wing. Shouldn't basic fiscal conservatism be a right-wing/conservative idea? It should be but it isn't! Right-wing, conservative politics has always been nonsense - constantly ignoring science and logic in order to make policies based around short-term greed.

I'm about as "left-wing" as they come, but all of my opinions match with what I would have expected right-wing policies to be about. But as it turns out, saving money, working to have a strong economy with a middle class that spends money, letting states make decisions themselves, etc, are all not right-wing policies at all! They are left-wing policies in the real world.

So where is conservatism? The thing the world needs most is a real conservative party in the US and Canada, one that does not hate immigrants, one that loves to clean up the environment (because it's going to save money to do that now instead of later), one that respects states rights.

Then the US elections could mean something again. But until then, it's not left vs right, it's just logic vs. stupid.

I have been conditioned to write code that is 2/3 compatible, that even when I am writing specifically for the PY3 interpreter the code turns out to be a __future__ import away from being valid PY2. I did not think much of them at first, but very recently, f-strings have changed that.

I think many people get imprinted with writing the PY3 code using only the features available at the time they switched over.

My favorite comparison of participatory sports vs spectator sports is with sex vs porn.

> [...] we ought to be more excited about the DIY home kits for electric vehicles instead of the Teslas and big automakers.

Can you explain why? Who is “we”? Are you anticipating that a sizable fraction of the 1+ billion gas cars in the world are going to be converted by DIY home kits? I personally can’t imagine hundreds of millions of DIY conversions (or even professional conversions).

Practically what I care about is (a) getting fossil fuel burning out of my neighborhood (and out of places where people live, in general), and (b) dramatically reducing the amount of CO2 we put into the atmosphere, on a global scale. As far as I can tell the way we will get there is by sales of new electric cars largely supplanting gas cars over the next 2 decades or so (also pickup trucks, buses, delivery trucks, freight shipping trucks, etc.).

Policymakers can speed this up by tightening emissions standards for all vehicles, banning ICE cars from some roads or areas, increasing fuel taxes, subsidizing electric cars, funding basic research in battery technology, etc.
I remember reading a website by a group of American researchers who had designed a plant, in some detail, where a nuclear reactor drove an atmospheric-CO2-to-gasoline reaction. The gasoline it produced was expensive, but not so expensive as to be completely absurd - a rise in oil prices and a fall in nuclear energy costs could make it practical. Needless to say, i can't find it now.

However, i did find this similar French work, which suggests taking advantage of the output from nuclear power plants at off-peak times:

If you are prepared to sink capital into a low emission energy source, then once you have sunk that capital, its opportunity cost, not actual loss cost (absent running costs) to get the energy.

In the 'real' world, the fact that you are reducing the wind speed by some fraction, or reduced insolation thermal temps on the ground, and that if you scaled this to one million square miles: those 'it doesnt work' sums don't apply.

it doesn't have to be efficient, to be worth doing, if you are prepared to sink capital into a source of energy.
One example is the Todd Rogers case (he's briefly featured in The King of Kong).

Todd claimed to take a polaroid of a score of 5.51 seconds on Dragster that Activision later "verified" (i.e. acknowledged).

Recently several independent gamers running simulation software demonstrated the score was impossible, that 5.57 is the lowest limit achievable.

But despite the mounting technical evidence Jace initially refused to take action, saying he'd wait a few months before deciding. Then 5 days later, after Rogers' friend and former TG referee Robert Mruczek (featured in KoK) wrote a long blog post basically saying Rogers was a cheater, Jace stripped Rogers of his scores and banned him from competition.

The criticism is that he wasn't fast enough to act on technical evidence but then arbitrarily relies on testimony from one person.

But again, I sympathize with the guy. To overturn a 37-year-old record based on what an algorithm says and what Activision itself said in 1981 is tough. If he acted right away that would have p* off others. It's a thankless job, IMHO.

But he had to know that when bought it.

It is surprising though that the order was non-deterministic, not only undefined. Determinism is something I intuitively expect from read-only operations like iteration.
Purely from an individual financial perspective this also makes sense. Take the example of the UK: fees are a flat 9k per year. At the end of a 3 year degree you're at least 30k in debt (usually closer to 50k with living costs). What chance does a drama graduate from an unheard of university have of paying that back comfortably?! Has their degree really added to their ability to earn? Add to that a whopping 6% interest rate on student loans. It's enough to make a young person depressed. A number of my friends now use less that 5% of their degree knowledge and have learnt most of their craft on the job. Maybe we could just skip uni and get straight to learning on the job? It just seems so much more sensible for a lot of careers (CS included).
I've only looked into this a little bit, but I think one problem is that you're limited by either nitrates or phosphates, depending on whether the algae are being grown in ocean water or fresh water. Either way you have to supply some kind of nutrient, which has to be either mined or synthesized in some energy-intensive fashion.
We need a college education to be accessible to anyone who is qualified

You should read the article:

The labor market doesn’t pay you for the useless subjects you master; it pays you for the preexisting traits you signal by mastering them. This is not a fringe idea. Michael Spence, Kenneth Arrow, and Joseph Stiglitz—all Nobel laureates in economics—made seminal contributions to the theory of educational signaling. Every college student who does the least work required to get good grades silently endorses the theory. But signaling plays almost no role in public discourse or policy making. As a society, we continue to push ever larger numbers of students into ever higher levels of education. The main effect is not better jobs or greater skill levels, but a credentialist arms race.

If college is mostly about signaling, then it's an arms race, and the faster the herd, the more the individual most race in order to keep up.

Accessibility to higher education is important, but much more of that education should be vocational in nature. Right now we have a lot of access to college, but that access has led to ballooning problems with student loans, along with Girard-style mimetic crises ( https://jakeseliger.com/2017/06/27/violence-and-the-sacred-o... ).
