It discriminates against people who value their time. Who in the right mind thinks that spending several minutes on captcha is ok?
The BTB was the real problem with Naples and the reason it sucked on non-trivial, branchy, pointer-chasing workloads like MySQL. With the improved branch prediction resources I’ll be interested in head-to-head of this rig vs. a Kaby Lake (or later).
Why would we call it “mini”? It is straight up NUMA.
Anybody expect 7nm processes to result in longevity issues? As far as I understand (and IME) the first components to fail are capacitors. Might that begin to change?

Apropos the article, I'm trying to convince myself to build an EPYC 3201 server now rather than waiting for the Zen 2 version, for which I presume I'd have to wait until October or November at the earliest.
It was fun seeing their materials refer to their branch predictor as a TAGE predictor. I remember hearing about the original paper for that when I was too young and inexperienced to focus long enough to understand it; then I saw a TAGE predictor show up in Chris Celio's BOOM repository, and I read it through.

If what AMD says is true, the new (for them) TAGE predictor in their industry-leading microarchitecture having 30% fewer branch mispredictions than the last, it feels very cool that one can read and somewhat anderstand the operation of a similar predictor in the leisure hours of a few days.

Also those caches are huge, wow.

Terrible experiences happen to me way more on the newer platforms I listed. People are literally crazy on those new platforms, I've had death threats (from a user which OfferUp never banned) and various other threats on those 3 platforms. Facebook, OfferUp and LetGo all ignored my complaints.

Craigslist over the past 2 years has had zero issues, I've interacted with fairly even keel 40+ year old people that are easy to work with. The "no lowballers, I know what I got" crowd has mostly departed Craigslist.
If you're willing to make your location known in order to take advantage of location services why wouldn't you want the very best possible service? There are complicated workarounds that can be used in place of Google's location services but none of them are anywhere near as easy to implement for the app developer or as easy to use or as accurate for the end user.

The closest unicode has seems to be NFKC, but last I checked it still didn't correctly handle greek and cyrillic aliases of latin characters, never mind anything more obscure.
I would call it a form of Non-Uniform Cache Architecture (NUCA). Linux definitely knows the cache topology and the scheduler is NUMA-aware but I don't know if the scheduler takes cache topology into account. It seems like it would be a small change to track L3s instead of NUMA nodes.
First generation anything is not as good as it's going to be.
pro-active complaining about predicted assholes. I like it.

For what it matters, you'll probably be right, but i'd have a hard time making plans with that outlook.
They claim aircraft lands light because it spent all fuel. Normally that's the case, but aircrafts are designed to land in emergency with fuel onboard, so that shouldn't be that big a problem.
It's NUMA, just like usual. The difference is the exact topology, and the real difference in latency (which changes the cost function of accessing from a different node).
> Unfortunately I don't know of a more authoritative source.

https://aomediacodec.github.io/av1-spec/av1-spec.pdf is the most authoritative source.

"All superblocks within a frame are the same size and are square. The superblocks may be 128x128 luma samples or 64x64 luma samples. A superblock may contain 1 or 2 or 4 mode info blocks, or may be bisected in each direction to create 4 sub-blocks, which may themselves be further subpartitioned, forming the block quadtree."

"use_128x128_superblock, when equal to 1, indicates that superblocks contain 128x128 luma samples. When equal to 0, it indicates that superblocks contain 64x64 luma samples. (The number of contained chroma samples depends on subsampling_x and subsampling_y.)"
Oh boy. Gonna have a huge RSVP line. I can't believe they thought these would last eight hours considering they only have about 200 or so from what employees are saying. There will be a line around the block for 24 hours if they don't do a form / queue / lottery. The components (without drives) cost about $1500-2000 each.
Yev has said there will be max 2 per person.
It's not NUMA since the distance from all the cores to main memory is the same (uniform).
2 fps isn't that bad considering the fact I believed that AV1 encoder's encoding speed should rather be measured by fph(frames per hour), or fpd(frames per day)
can you pick me one up to, and ship it :)
Interesting perspective, but let me throw out this perspective from Sun Tzu:

The greatest victory is that which requires no battle.

Part of why we invest in defense is to ensure we never have to fight. True war is costly, by definition.

It should be used as a last resort, when no other tool is available. Conversely, if you do have to deploy it, you want to be sure that it “changes the equation”. In other words, If it didn’t truly hurt/disable you or your opponent at the end if it, then there was no reason to do it in the first place.

How does this relate to current US defense posture? In short: we want to make it such that no one wants to have a real fight with us, that instead they prefer discussions/diplomacy (at least at the nation state level).

While folks complain about how much we spend in defense, a lot of it is not for the result per se (though ensuring cutting edge capability is important), but more to make the point that we are spending X times a given country A. This is intended to make country A less interested in being a bad actor to the US.

Is this perfect? Probably not. Is there lots of waste? Certainly. But overall it has generally worked, and as such underlies much of why the US does what it does with military spending.

Ah, GPU passthrough?

My biggest problem with virtualization is USB. I have a libvirt with GPU passthrough setup that works great, but have been unable to get a USB controller of any sort to passthrough; always winds up in a group with a bunch of other PCI-e devices. And ordinary forwarding with SPICE or something isn’t really sufficient for what I’d like to set up...

Ah, the magic of financial engineering. Mr. Neumann will cash out of his fictional decacorn in dribs and drabs and never have to work again.

I imagine what you are proposing then is to record the entropy on the password when you first register and for accounts with sufficient password entropy to not ask for a captcha after few failed attempts.

With that, the site gives away whether the account has a low entropy password or not.
I don't have a problem with the theory of targeted ads, in fact as a consumer it is actually useful. If you start looking for a pair of boots, then see that a brand you like but was out of your budget has a sale on, so you buy those boots you really wanted but couldn't afford. That's useful for a consumer.

The problem is that targeted advertising mostly just sucks. Last year I bought wireless headphones from Amazon, and everyone I visited them again for the next two weeks I had recommendations to buy wireless headphones. So even Amazon can't do it properly. What if I'd browsed on Amazon and bought from another store?

The other day I saw an ad on twitter for an wine company, in the "why am I seeing this as?" section it said that it is targeted to males (yup), aged 35 and above (no) who live in the United Kingdom (no). And to top it off, I don't even drink.

The problem is targeted ads mostly don't work, their targeting is so simplistic (see something you like, then blast you with ads for that over and over) or just assign you to such a general bucket (age range and location) that it isn't useful. Even "likes" aren't that useful for targeting - just because I "like" a brand doesn't mean I want to be blasted with ads from them or am going to buy every product they sell. I like Thinkpads, but that doesn't mean I'm going to buy every new ThinkPad that is released.

Not sure why you see that as useless; it's basically the moral takeaway from Hamlet. There are many situations where it's best to not join in 'the game'.

> 100% of Android apps do not work on PureOS. F-Droid alone has ~1800 apps.

This is a fair point. It's not a huge argument for me because I'm only interested in maybe 20 categories of app and I've never been thrilled with the 30 contenders in each category. For instance, if it has only one browser and that one is Firefox, that will be ok with me to begin with. It won't bother me if there are five other choices in F-Droid. But in general, more choice is good, so I grant that this is an important consideration.

> Are the Snapchats and Instagrams of the world going to port their apps over to this entirely new platform when they can't even be bothered to make versions of their Android apps that work without Google's services?

Android without Google's services is a tiny fraction of Android and a smaller fraction of the whole market. PureOS or anything else with even smaller share can expect to be similarly ignored. But Android sans G seems even less likely to go viral than something else.

For one thing, it's too fractured. There is no AOSP brand. There's a bunch of little no-names that happen to offer AOSP under some name that isn't "AOSP" and has no recognition at all. If two or three lower-tier makers offer "Brand C" phones, it could spark. Maybe not in your neighborhood. But if it catches on in India or Malaysia or Brazil, it might be enough to attract Instagram or Twitter. Remember that those companies don't want to depend on Google. They very much want Google out of the picture.

So a handful of apps can legitimize a new platform that is attracting a million or ten users anyway. Then it becomes perilous not to be on that platform. WhatsApp can't afford to let some up and comer get a foothold just because WhatsApp wasn't available on the viral new platform.

Ahhhhhh. Ok I'm going to quit dreaming for now and get back to work. I'm not holding my breath, but I do think it can happen. It just takes the right lucky timing. There have been so many helps lately that I think if there was something ready to take advantage of these incidents, the timing is right.
Wow this is really tempting for me to make the trek down from Portland. I run a storniator which is pretty similar to their 3.0 pods and the thing is a beast.
I don’t doubt backblaze is truly giving these away with no strings attached, but even if I was in the same neighborhood, I would assume somebody more determined than me is already waiting with a uhaul outside the pickup spot.

No, I actually misread the comment in question. I thought @dev_dull was saying that people who don't want the government to limit individual freedoms were the same people who want the government to regulate corporations. After re-reading the comment, I can see that this wasn't the message.

However, there's still the fact that @dev_dull is not distinguishing between people arguing about government restricting individual freedoms and government regulating corporations. It's not about whether people can be trusted with high interest cards, it's about whether corporations should be allowed to set any interest rate they want.

> It has no notion of virtual or physical memory.

Exactly! That's why once virtual memory is allocated, malloc() is allowed to consider the operation successful. The standard does not care at all whether it is virtual memory allocation or physical memory allocation. It is completely unspecified in the standard what sort of memory must be allocated. So no spec in the standard is being violated by returning non-null pointer for virtual memory allocation.
Although Threadripper 2990 is not uniform to main memory, which adds a wrinkle

So now there’s at least 2 levels of Non Uniform access to manage by the Bios/OS
I really want to read the perspective of some great contemporary thinkers on this. Who were the thinkers writing about this in a compelling way and who it's likely that in 20 years or 50 years we'll be able to look back on and say their essays really understood the zeitgeist?

What shocks me is how companies and organizations have reacted to this. Every time a significant decision is deferred to mob rule I feel a little bit of power departs civil and ordered society and is transferred to the mob. Which seems to me to validate the notion that we ought to be afraid of mobs. That's a pretty scary society to live in and doesn't really mesh with the principle of rule of law.

The only reference point I have for this is historically the utilisation of and empowerment of angry mobs has coincided with times of great political turmoil such as a revolution. And that historically at least you could say that these mobs are created by breaking down the existing structures of authority. I think you can find a reference for that in Western society where the power of traditional moral authority or institutional symbols of authority have declined or been dismantled.

Probably the least controversial idea I have as to a cause of all this is that there must be a huge amount of potential emotional energy present in the population that is being directed towards are tapped by these expressions of outrage and mob outburst. I think it's reasonable to say that this potential emotional energy was not created by these topics it was created elsewhere by foundational issues such as economics but it's being directed towards these topics perhaps as cathartic outlet.

> ... for the issues to which AMD is vulnerable, it has implemented a full hardware-based security platform for them. The change here comes for the Speculative Store Bypass, known as Spectre v4, which AMD now has additional hardware to work in conjunction with the OS or virtual memory managers such as hypervisors in order to control. AMD doesn’t expect any performance change from these updates.

Which Intel CPU generation will have hardware fixes for these Spectre variants?
For those interested, this information (~200 units, 2 per person) was shared on Reddit and wasn't on the original article. As for the time-frame, if they manage one transaction (giving one person 2 units) per five minutes on average, they roughly fit into eight hours.

Are you sure? NASA still seems to use Snoopy in an official capacity (e.g. the Silver Snoopy award). Starting in the 80s they even started sending every Silver Snoopy pin up into orbit before it was given to the recipient.
Redfin looks like they're trying to be a "discount agent". Here is a quote from their front page:

> We're full-service, local agents who get to know you over coffee and on home tours, and we use online tools to make you smarter and faster.

This isn't what I had in mind at all, and I'm not surprised they have trouble getting traction with that approach. If they save you 1.5% on your half, but the other agent still gets their 3%, you'd only save 25% of the thousands you spent in middle man costs. Meanwhile, all the 3% agents out there are applying pressure to see it fail.

In the ideal case where they get both sides, Redfin is only saving you 50%. There is no reason home sale paperwork should cost thousands of dollars to process. Someone like Amazon could eliminate agents altogether.

Here is another analogy - imagine TurboTax charged you a percentage of your yearly income instead of a hundred dollars for the "Deluxe" version. That would be insane.

The whole point of owning something like VTSAX/VTI is that you're not overly exposed to any company. They currently own 3,607 different stocks.
Break up how to overcome it
I always envisioned their devious model to be something like:

- You want to train on an unlabeled dataset, label it along the way.

- You have a set of untrusted validators, some with no history, some with known credibility and accuracy scores. And you have a lot of them.

- You do kind of a zero-knowledge proof by showing the unlabeled dataset to validators that you know you can trust because of their historical high success rate, which you've already established through asking them to label a dataset that you already have high confidence on.

Kind of like how a blue-green colorblind person could find out which pen is blue, which pen is green if he is surrounded by people he can't fully trust. Ask people around you and maybe even show the same person the same pen (or a really dead-easy captcha) twice in a row. If they lie to you both times, they are not to be trusted.
The goal isnt to prevent it in an absolute sense. The goal is to raise the cost to either above the value of the data contained therein or compared to other direct means, like in person espionage or military actions.
I think it's funny that some of the crazy new features we're seeing in bikes, like bamboo/wood hardware and direct gear drives, are already covered in this book.

I'm not surprised. Amazon's entire MO is a relentless focus on the customer. They do that by methodically optimizing and controlling every aspect of the supply chain right up to the moment the product is handed off to the customer. And they get better at it every day.

Restaurant delivery breaks that model. There is too much variability. Too much can go wrong outside their control, and they don't have enough leverage to change it.

If they can't win (even at zero margin) and can't make customers consistently happy, why be in it at all?
The calculation gets more complicated with appreciating land, and leverage.
