Power9 is basically "Bulldozer done right". Each SMT4 Power9 core is incredibly fat, with 4x load/store units 4x ALUs, 2x Vector units. Bulldozer probably would have called each SMT4 core a collection of 4-cores.

But only 1x divider, 1x crypto unit per SMT4 core.

The chief downside to Power9 is that it only supports 128-bit vectors, and these 128-bit vectors are executed by ganging-together the ALU units. (so 4x 64-bit ALUs == 2x 128-bit vectors processed per clock tick). Compared to AMD Zen (4x 128-bit pipelines), AMD Zen 2 (4x 256-bit pipelines), and Intel Skylake-X (3x 512-bit pipelines), Power9's SIMD capabilities are tiny.

Another oddity: most instructions take 2-clock ticks to execute, even simple instructions like XOR or Add. This increased latency is likely the reason why it performs so poorly with Python / PHP code.

But when code is written for Power9, it works quite well. Stockfish chess seems to work extremely well on Power9, likely because Stockfish scales to many "cores" well (fully taking advantage of SMT4), and only has 64-bit operations.

One more wildcard: Power9 has 10MB (!!!) L3 cache for every 2-cores. That's 90MB L3 cache on the 18-core. I presume that real-life database applications would benefit greatly from this oversized L3 cache.

EDIT: It should be noted that the L3 caches serve as victim-caches of other L3 caches. So Power9 core-pair 01 can have its 10MB L3 cache serve as a "L3.1 cache" of core-pair 23. AMD Zen / Zen2 L3 cache CANNOT use this functionality. So AMD Zen2 64-core may have 128MB of L3 cache, but each core only "really" can go up to 16MB of L3 cache (because the other 112MB of L3 cache is only for other cores/module)

EDIT: Also note, Power9 came out a few years ago at 14nm, while Zen2 came out on the 7nm node a month ago. I think a new 7nm Power9 update is planned, but I don't know what its timeframe is.

In effect, you could have 1-program using the entire 90MB L3 cache for itself on Power9. While AMD Zen2 requires (at minimum) 8-programs, each program using only 16MB L3. This design decision is clear in the intended use of the chips: Zen2 is clearly targeted at the cloud-market, while Power9 is big-iron / databases.

--------

Unfortunately, most of the benchmarks these days show that AMD EPYC / Rome is just the better overall processor. Still, 18-core Power9 is relatively cheap: a complete 18-core / 72-thread system for $4000ish: https://secure.raptorcs.com/content/TLSDS3/purchase.html

Cheap for Power9 anyway. AMD EPYC is also relatively cheap. You can get a 16-core / 32-thread / 32MB L3 cache AMD Ryzen 9 3950x for only $700 these days (and maybe a complete system build for only $2500).
Ah, good point. Thanks.
> promise for Linux support that ARM and RISC-V don't necessarily provide

uh, ARMv8 and RISC-V were developed with Linux in mind from the beginning, they didn't even have anything other than Linux/BSD/various-RTOSes, like IBM did with AIX.
But that'd just create more echo chambers and destroy their engagement metrics, right? I feel like the contemporary draw of Twitter is the discourse.

> I can only assume the "nothing to do" retirement crowd didn't do much when they were working, and therefore have no idea how to fill the time.

Well, the common pattern seems to be for those who retire early that it was preceded with a lots of work. That was also my case. At some point I just realised that I want to do something else, and I had enough savings for lifetime so money wasn't any kind of motivator any more. So, previously I was working 24/7, then suddenly I was working only couple of hours a week. Slowly I started picking things to do, but it takes a lot of time to find hobbies etc.
If businesses started creating child companies (for any reason) it would result in substantial job creation.. so this sounds like a win-win to me.

It's going to be highly dependent on the workload. For some it's counterproductive because the working set of fewer threads will fit into a given cache level when more threads won't, and then it slows things down -- but then you can turn it off or run fewer threads per core.

Where it's a big win is for pointer chasing workloads or big databases, where the working set isn't going to fit in cache anyway and then it's effectively like having really fast context switches. You have four threads and three of them are waiting on main memory while you keep the core busy with the fourth, then that thread has a cache miss but by then one of the other threads has the data it was waiting on.

The other side of the coin is after you've built a few startups, you see the same pattern coming up again and again. Part of being creative is to know where to focus your attention (I.e. figuring out PMF) rather than wasting cycles on problems with clear solutions.

Totally agree, I should have italicized between most suburbs and small town centres in the quote.

Biking to work in Mountain View was a pleasure and seemingly very safe. I'm now in a rural area with unmarked roads that barely fit two cars. The state highway between me and the nearest town has a paved shoulder that might be a foot wide. If I ride on it I commit the mortal sin of riding against traffic because I have a wife and kids and need to make eye contact with everyone coming my way before I even think of trusting them.
While data points do help, impactful startups often change the paradigm and how things are done. So, again, I don't think relying too much on emperical data points is good for founders. If you do, you'll rarely do something interesting and new.

Sure, it becomes an arms race, but I think your garden-variety kid trying to sneak into clubs is A) not getting caught for this reason, and B) not being told what's faulty about their fake ID even when they do get caught.

> Let's suppose that's true.

It is.

> You didn't think it was relevant, in response to a question about whether you might not be impartial because you worked for Google or Apple, to mention that you worked at Apple a few months ago?

I didn't find the question that was being asked to be relevant, since Apple has nothing to do with this article and I have never worked at Google. In any case, if you're actually looking for my opinion on this topic, I suggest looking at this comment, which is basically saying what I was too lazy to and which you can judge for potential conflict of interest yourself: https://news.ycombinator.com/item?id=20749104
This is very simplistic. Managers often expect employees to be able to prioritize a bit; many managers consider it to be an important trait. Moreover, many managers say things like, "Do you wanna do the TPS reports now?" while they mean, "It is time to do the TPS reports now." It is a colloquial way of speaking that non-Aspie/non-autistic folks generally pick up on. That is the point of the article. There is no reason to posit incompetence.
There is a huge "in nominal values" that has to be appended at the end of that claim. Reality is always more complicated.

I didn’t read the statement as a universally applicable principle, but rather a description of the current situation.
> The debt still has to be paid back with interest

That's true but kinda also not true. There has to be the possibility that the debt is to be paid back. More important: the interests have to be payed. Rest is cashflow management.

Hypothetically more infrastructure would mean more taxes and so one. Like in SimCity.

Just think of it this way: where does the money comes from that the state makes? If it is not spend the state has all the money but no one else.

It's more like activa and pasica on a balance sheet
The emotions of your dog are not laws of nature.

The "true market" is like "no true Scotsman" or "a closed system" or "a spherical cow on a frictionless plane". It assumes something that doesn't exist. In economics the influence of the things it assumes wrongly can be very significant. In physics wrong assumptions can also make the results wrong and a lot of work (or rather most work) is done on checking if all the assumptions are sound and ensuring that the influence of the remaining gaps are negligible. That is something that is hard to do in economics when it involves interactions with the global market.

Yes, special theories can be precursors for more general theories.
Not to mention most are paying taxes as well (via ITIN) and aren't qualified to receive certain benefits.
My point is they're not saying "ONLY do things that don't scale". It's more like, "from time to time, ALSO do things that don't scale". Which, as I said, I think is good advice, but also pretty common sense.

Can you elaborate? It seems to me that if a single corporation just split their operations into multiple separate child corps, it wouldn't necessarily result in job creation. (Duplicated positions could just be contracted to a single company in the group, for instance.)
Having lived and experienced the aforementioned blackout (> 55 million people, https://en.wikipedia.org/wiki/Northeast_blackout_of_2003 )

It was a transformative experience to me and it felt everyone else who experienced it regarding the hidden importance of these infrastructure pieces.

What I loved about this piece is it reads much like so many people's experiences of the incident. Even though it happened over 15 years ago, I and most others remember distinctly and with clarity the sequence of events that occurred on that day. Seems like most people's stories went somewhere along the lines of:

- Interruption of an intended activity due to no electricity

- Attempt at understanding scope, and an effort to substitute the interrupted activity (in my experience, we were entering a restaurant for food and was told "given we don't have power, we can't microwave most of our items - but the oil in our friers are still a bit hot though so you can have fries... We wanted to try elsewhere).

- The realization that this was not a localized one block situation, but something larger and more serious. (We drove around and the traffic lights were out, put on the radio (most most stations were "silent"). The few that were didn't even know what was going on "it appears there is a blackout, getting reports from as far as <X>" with <X> being of an increasing scope as the hour went on.

- Then an abandonment of the days plans for a trip "back to shelter/home" where one nestled and tried to wait it out until services were re-restored.

The natural gas in our home didn't work either, so the only way we could heat food was on a fire. It's one thing to realize that all these these are connected, but its another to feel its connectedness through these services' absence.
And that's intersectionalism. I think the missing piece of this article is that every relationship is going to be unique. Where in the case relevant a woman manager can go 'oh yea, autism' and adjust their behavior with that employee (because as this article tries to describe, the autistic employee probably doesn't even understand the difference in behavior unless they spend time focusing on it, and even then they probably won't care).

But my point is that we should accept diversity, and the intersectional interactions that will come from it.
Also a person that is rational, and a person that is rationalising, are opposite meanings: rationalisations are deeply irrational.
>Generally they don't harass people unless something seems amiss and there is a large enough discrepancy to justify it.

There are lots of anecdotal reports to the contrary of what you just stated. Do you have anything more than anecdotal evidence to support your statement?
I don't think it's about disk space at all.

Read only browse means nearly all the same code, with whatever vulnerabilities it has, is there and needs to be supported. I'm sure a good chunk of removing the all Mercurial support is not needing to keep an eye on the code to allow repo browsing, etc.
Sounds smarter.
Life straws suck to use as a primary means of getting water...

The USGov has failed in the past at an individual response level, but they're really good at compiling resources to help you and your family be independent. In fact, in San Francisco, the Emergency Response mindset for The Big One has shifted (since loma prieta) from "the government will come help you when it happens" to "do everything you can to survive for weeks without government help, when it happens."

So in your case, do more than buy life straws - store many gallons of water somewhere in your house. This can be done really easily and cheaply - save your used water bottles if need be, or just go buy a big giant plastic drum and drop some purifying tablets in it.

Keep bleach and eyedroppers in your house for when that water runs out and you need to refill with questionable water.

https://www.ready.gov/ has shitloads of easily digestible resources to prepare.
As I mentioned, data-points can help steer in the right direction. I'm definitely not talking about disruption or changing paradigms. The same way a YC can't guarantee each startup will disrupt an industry. All they can do is help make something good, go to great faster.
I am in the process of making a major life change to focus on remote first work. I've recently moved and I am currently looking to purchase a house in a small town from where I plan to work full-time.

I think the caveats people bring up are serious and require careful consideration. They are part of why I am trying to find a company that is "remote-first" and I would prefer to avoid companies where I am one of a handful of remote employees while the rest of the team is co-located in one or more offices.

My major fears are:

* I suffer from isolation and loneliness and it impacts my mental well-being

* I find my career progression stalled

* I miss out on more lucrative compensation

* I find my coworkers making decisions without consulting me

* I experience an increase in general anxiety

* I find my productivity and focus to be significantly less

* I am unable to balance work/life when they are combined in the same place

The worst case scenario is that a combination of my fears being realized forces me to recognize my unsuitability for remote work. I would then be stuck in a smaller city with less opportunity, potentially with a mortgage. I might be forced to sell my home for a loss, to move back into a bigger city and to attempt to find a normal job to rebuild my retirement savings.

My plan to mitigate these is to be aware of my fears and to put into place strategies that can deal with each one. I believe that companies that plan to be remote-reliant in the future will need expertise at the management level to deal with those issues throughout their workforce. Where there is legitimate fear there is also opportunity. I believe that all of the problems associated with remote work can be handled if they are openly discussed.
I agree, I don't now that for a fact. It's more a form of rhetoric to trigger interesting discussions. Seems to work ;-)

Propp himself (the author) wrote a paper in 2012 called Real Analysis In Reverse, which he links to in the post but doesn't really call attention to. It's a lovely paper, and it talks about precisely what properties of the reals are enough to tell you that you really are dealing with the reals - like his example of the Constant Value Theorem from the post.

Indeed, we should all cower in fear to avoid offending the lobbyists.
I don't see any guarantee here that splitting a business will create jobs.

1) Business A has 1B in profits with X number of employees, gets taxed.

2) Business B splits into 10 businesses with 100M in profits and X/10 number of employees per business unit, and doesn't get taxes.
I wonder if these guys realize that this sort of research will be weaponised
If your browsing history is of value, than giving it (or even just the portions of it that are manually typed into the url bar) away is a cost to you. You can't point to a dollar amount on an invoice, so in that sense it's not "non-theoretical." But if you believe that personal information can be valuable -- and it's pretty clear that it can, especially in the aggregate -- then calling this a "cost" is not a joke.
Would you rather pay 2x your rate for electricity (~$1K/yr) for redundant power, or would you rather drive to the next town over (~$1K/5yrs) during an extended power outage?
"Allowed" is too coarse a term; there are too many variations and details it can't cover.

I second this. Also, read the Declaration of Independence. It is quite succinctly stated the long list of grievances that led to the founding.

Of course, actually taking that into context takes away some of the dopamine hit from trying to spread the elite hatred that is currently in vogue.

I'm not even saying there is anything wrong with disliking the elite now; just keep in mind then is then, and now is now. The issues are of course going to be different, even if there may be a shred of commonality to them.
agreed. wired headphones are the way to go.
It's not. He's directly refuting the claim made in the title of the blog post. That is: Most startup theory is ex-post, therefore bs.

In the title, the author is seemingly making the claim that all ex-post startup advice is BS. The commenter is debunking that claim by providing sound ex-post advice.

If you want to understand Yvon Chouinard as a person beyond reading Let My People Go Surfing, you should watch "180 Degrees South: Conquerors of the Useless"[0]. While Yvon only appears for about twenty minutes within the movie, his presence is woven all throughout the film.

Part of what made Patagonia as a company different is the no BS mentality instilled within him from his dirt bagging days spent climbing around California, Patagonia, and New Hampshire. There's a wonderful moment in the movie where Jeff Johnson and Yvon are climbing some first ascent and Jeff asks "what should we name it when we're done?" and Yvon replies, "nothing, just climb it, be done, and go home".

> It pains me to say it but he is a Luddite.

A Luddite would argue that the technology (NB: not the implementation or design but the very concept) takes something away from quality, morality, and/or spirituality of life. Thus, Luddite Stallman would refuse any help from anyone using any kind of handheld communication device including walkie talkies, free software laptops over wireless access points, etc.

Stallman is instead a surprisingly pragmatic free software advocate. He ignores software which runs as if it were low-level hardware circuitry (and says very little about hardware since it can't be produced with anything near zero marginal cost). Plus he qualifies his stance against cellphones as a symbolic stance against mass surveillance.

I don't see any difference between that symbolic stance and, say, a celebrity who tries to have a zero-carbon footprint in their abode. The inconvenience in cost is obviously in service of the benefit of raising awareness, which he does every time he's asked about how he gets around in the world without a cellphone. Not everyone gets royalties from TV drama to pay for a fancy house and not everyone can outsource their schedule to friends aren't serious criticisms of symbolic stances.

Edit: WRT pragmatism-- I'll be interested to see if FSF approve the Purism Phone. It's got a proprietary baseband OS but that can be turned off...
