When I'm taking photos of food and cocktails for my side gig, I generally have a shot setup in my head prior to food arriving at the table. I'll choose places with natural light, near large windows to diffuse, or some interesting backgrounds and pretty lights. But once the food arrives, it's very much shoot as much as possible from various angles. Even a single angle, I shoot at high fps. That guarantees you at least once of the shots is the sharpest, and even slight variations of positions will work better than the other. Trying to be perfect just leads to missing shots. Some dishes deteriorate quickly as they cool off. Shoot lots, and choose what works best with your style. Often times, you'll get something unexpected that you didn't see with your eyes initially.
He said super conductor. So no losses. Jus the cooling costs but we could insulate it really well.

High voltage dc might be another option to minimize losses.

I think more CPU performance is attractive if you edit photos or movies - something that is typical for a home computer.
The reason AMD provides CPU performance through a high core count is because it is power efficient, otherwise a single-core is easier to program.
And also its sequel Rule 34.

Thanks! Good read.
How much power would an Intel based system need to get that 40% performance boost?

> it boggled my mind that they wanted to charge me, a GE employee, money to use Predix on projects for GE.

This is common in very large companies because an easy way to justify a new business unit it to claim it will pay for itself by charging other business units as well as external customers.
If you check Phoronix, they found it doesn't actually take much more power than the 7980XE.

What exactly is wrong with that?
> Maybe in making the eggs and toast, you leave the house a second later, and a driver that ran a stop sign that would have hit you passes in front of you instead.

This is likely unimportant to answer the questions that the simulator is supposed to answer, which means that no one would ever bother running one ancestor simulation--as you define it--when they could instead run multiple trials of a different kind of simulation for the express purpose of eliminating such confounding "want of a nail" moments. "We ran this ancestor simulation for 10 million years to find out what logfromblammo would eat for lunch on 13 August, 2018, and the results were ruined when the simulated logfromblammo was killed in traffic that very morning, just before the entire simulator planet was demolished to make way for a hyperspace bypass. We'll check the budget to see if we can reset for another run."

Maybe the other driver also had a breakfast that delayed their departure by one second, and now they hit me again. In one ancestor simulation, you won't know all the various circumstances that contribute to the causation of an event. If you do cut corners, you can say that there is an X% chance on any given day that I get involved in a traffic collision.

So an ancestor simulation--as you define it--is functionally identical to walling off a piece of your own universe, rearranging matter inside it to conform to initial conditions, and then watching it to see what happens.

If your universe is itself a simulation, how does the parent universe detect the difference between someone running a simulation and Magrathean-scale engineering projects? If I commission a planet that is a perfect copy of Earth on the day before Lincoln was assassinated, and black-bag Booth an hour before he shows up at the theater, is that an ancestor simulation? Do I need to wrap it in a perfectly black shell and project sunlight and starlight through it from time-appropriate locations? That only requires that the star you use for energy is a bit more energetic than the sun. If you simulate a planet that predates astronomy, perhaps to see what would happen if dinosaur-like creatures hadn't been wiped out, you wouldn't even need to do that. Your total energy requirements for the lifetime of the simulation are the delta-v required to build an Earth-like planet with a Moon-like moon and move it into an Earth-like orbit around a Sol-like star.

We wouldn't be able to detect if our planet is a simulation by dinosaurs, to see what would have happened if their planet had suffered an extinction-level event before they launched themselves into space. How do you tell the difference between a naturally-formed and artificially-constructed planet? Likewise, how do you distinguish between someone trying to compute an ancestor simulation and someone just running an immersive MMORPG? If you did create a single ancestor simulation larger than a few interacting atoms, it rapidly loses its scientific power, due to all the variables you intentionally did not constrain. How is that not just an amusement park?
I had thought all repeals were also laws? The Wikipedia page says this of the USA, but is more ambiguous about my own country (UK, for now).
It reads like a Slashdot comment, 50/50 odds on whether it would be modded +5 Funny or +5 Insightful.
I agree. The societal view that joining the military and dying is a just and selfless act worthy of our thanks and praise has to end. More so when justification is to protect "our interests" and "our way of life" - when said way of life is to better ourselves due to the exploitation of others.

Until the military is seen for what it is, war will be continual and cyclical until we destroy this planet and make it all but inhabitable.
Because all of the containers may not be of the same operating system? Networking on containers is also a bit different.

There are also reasons for having some more isolation between guest OSes.

On my ESXi box at home I have:

* A VM that hosts my NAS shares. This does nothing other than host the NAS shares, as I want to be sure no silly experiment of mine interferes with that.

* A general-purpose VM, where I do run some containers out of (UniFi controller, Plex, etc)

* A VM running Windows Server for my Domain Controller

* A secondary vSwtich with isolated no uplink to the rest of the network. This is my mini malware testing lab.

* A VM running pfSense that I'll sometimes use to allow selective access out of the isolated vSwtich out to the internet, but not to the rest of the network.

Can't do all that with containers.
We already know how to get arbitrarily close to 1C: just keep adding energy to the system to produce enough thrust to overcome the additional mass of said energy's source and the relative mass increase from getting closer to 1C. It's just not practical and the laws of physics forbid it from ever being practical.
I've no experience with your situation. However, when I am burned out, I travel to mountains to hike/trek. I disable all communication apps on phone including email. Funny thing is, after I come back, sometimes I forget passwords. That's how I know I have been totally out of it.

I would suggest you take some time off and do something that you enjoy. Something different from what you do everyday.

Frequently, yes. Theoretically, you can have an artist that is well-behaved and interesting. But we don’t get to make that choice and you can’t custom order creativity to take the good bits and leave the bad bits (although crispr gets better and better).

Especially since if you start blocking out the unsympathetic artists early in their career due to being jerks and criminals and whatnot, this would have prevented many of the great artists.

For example a letter in 1968 shows John Lennon as a wife beater amongst other deplorable things [0]. Stopping him at this point would have deprived the world of many creations.

Distance from Americas to Eurasia by sea is under 55 miles. https://en.wikipedia.org/wiki/Bering_Strait

"Hard-boiled Wonderland and end of the world" by Murakami. Not exactly a cybercrime novel. But I find the novel to be resonant with SF/cyberpunk subculture and an engrossing read too.
"What did they expect?"

To have privacy in their hotel rooms; to not have their lock picks stolen by hotel staff; to have some way of distinguishing these "security" guards from random strangers trying to take advantage of the situation; to tell the staff "not now" and have them listen; etc.

None of that is unreasonable. I would have canceled the remainder of my reservation if a hotel treated me like that, and I would not bother going to conferences held at those properties.
This is the kind of hardware Apple would be shipping for "Pro" if they cared.
I stayed at a hotel in Santa Monica last week, and declined cleaning services. They left a card that said they would enter the room every other day, regardless of the sign I put on the door. It was annoying to make sure I packed up all of my valuables and carried them with me the next day, but as far as I could tell they didn't actually enter the room the next day. There was another identical card under the door when I got back, and my "tells" weren't disturbed.

Kilometers-long water streams for a space tower and to fight wildfires
Proposal to use ultra high pressure water streams to hold aloft a space tower, to produce kilometers-long water streams to carry water from nearby lakes to fight wildfires, and to transport fresh water kilometers distances to drought ridden areas:

Pumping pressurized fluids to high altitude for the space tower and for fighting forest fires.
http://exoscientist.blogspot.com/2018/08/pumping-pressurized-fluids-to-high.html

Entrepreneur Peter Diamandis who began the successful X-Prize for the first amateur team to reach space once said, if you want to make a billion dollars, develop something that helps a billion people.

The fighting wildfires proposal can help millions and prevent billions in property damage but the application of transporting water to areas in dire need of water resources can help billions.

To be completely honest, I don't use the nub. The trackpad was 5/5 on the MBP, but I feel the trackpad is 4/5 on the X1. It's plenty fine to use... I also carry a portable mouse in my laptop bag.

Developer Driven Testing
AMD has manufacturing cost advantage - CPUs are built from 4- core CCXes that can be binned separately.

Intel on the other hand needs to manufacture a monolithic CPU that not only is fault free in enough cores, but performs well. That's harder and yields are way lower.

80% yield on a 4 core block is a 16.7% yield on a 32 core block - and that's before binning
If you want to run multiple different OS's (or even different distributions of the same OS) containers don't work.
> Reading a Harlequin novel?

In general, a work in a visual medium - a painting, a comic book or a film - supplies ALL or most of the inputs. A book supplies only some of the inputs and we, the readers, supply the rest.

Here's the thing: a good reader supplies good inputs and an average reader supplies average inputs. This is why children are described as "imaginative readers". They "live" in the story-world whereas we adults skim through it.

So even if it's a Harlequin novel, you can make it as vivid as you'd like. But that effort will be substantially more than watching even a good film adaptation of a Harlequin novel.

This is the perfect chip for continuous, low-memory number crunching. For everything else... not so much. I mean,
this chip consumes 74W when idle, of which almost 90% are spend on the interconnect. That's insane. Most important bit in the review for me:

"After core counts, the next battle will be on the interconnect. Low power, scalable, and high performance: process node scaling will mean nothing if the interconnect becomes 90% of the total chip power."
Occam's razor says he most likely meant what he said.

If a program errors into a non-recoverable state, and I see something in the stack trace, odds are it had something to do with the issue.

He showed intent to send a message. The fact he was about to end his life just amplifies it. Of all the things one could have focused on, that stuck out? Hardly dismissable.

He knew where his life was going either way. Either because he would have ended it regardless, or because he knew that doing anything drastic enough to hurt the "people" who he saw as the source of his hardship would forfeit his ability to live any semblance of a normal life afterward.
Everyone? I remember a large contingent defending microsoft. Remember Saint Bill and his magical "charity" foundation that is curing all of the world's ills?

Lately, there have been a vocal group defending corporate interests, globalism, monitoring/spying and censorship all over social media. Not sure why and where they came from but it's interesting how suddenly they appeared on the scene.

Shortsightedness in American business never fails to amaze me. You would think that a company as old as GE would be able to recognize the difference between capex and opex, but these sorts of missteps still seem absurdly common.

Even GE still struggles to understand software. It gives me hope that software engineers will become the next class of power players and the whole thing isn't going to get subsumed into finance like everything else. Even Apple is falling prey these days to finance-thinking.

Can you point to specific tweets?

I scrolled down for quite a while and what I saw was a mix of pro-Trump tweets, stuff about Romania and communism, and the only things I could find related to gender were tweets stating sarcastically that the actresses who slept with Harvey Weinstein ("sleazy producer") had no moral agency, i.e. they did have moral agency. Is that what you mean?

To each their own, but if the MBP is 5/5 the trackpad on the X1 is still a 1/5 to me. I hate the thing. I also never use the nub.

"Spam Kings" isn't bad either. A bit dated, but it's a good history of one of the earlier spam operations.
Yeah, I was really surprised at the lack of back lanes in Santa Monica. There are some, but not enough.

People did treat them mostly like bikes. Bikes aren't allowed on the sidewalks either, but that's where many people ride them.
I have many use-cases where containers are simply unsuitable.

I'm using FreeBSD, but these apply just as well to Linux. I wanted to run ZoneMinder, which is not available for FreeBSD, so I simply spun up a CentOS VM and installed it.

On the flip side, I wanted to run Home Assistant, Node-RED, and some related utility programs. All of these are happy to run on FreeBSD, so they can live happily in a Jail (FreeBSD's equivalent to a container).

Some people virtualize their router by dedicating a NIC to the appropriate VM. I don't know if this would even be possible in a container.

No. You can't delete a law by making a law, that's obviously a contradiction.

All repeals are acts of Parliament. However, Acts are essentially diffs to the existing body of law. If you read one you'll see they're full of "insert paragraph X after paragraph Y" type language. An act that repealed a law would just be an act that stated such-and-such a paragraph in the law was to be erased.
According to Wikipedia HVDC lines are <3% per 1000km[1]. So that leads to ~46% loss for 20000km.

If they could get it down to 1% per 1000 km, then it's only ~18% (for some value of only).

I always liked the competing theory the wolves/dogs were responsible for domesticating humans. Mostly because I have seen first hand dogs train humans.

For example, my parent’s Goldendoodle knocks (punches) a sliding glass door when she wants to be let in/out. No one taught her this, she did it and got the response from the human she was looking for and continues the behavior getting the same expected result from the human everytime.
According to StatCounter, Android has 74.2%, while iOS has 24.15% of the European market.

Oh yes, I understand that, but as the article points out, focusing on this short-term revenue metric is such a flawed approach to something like the GE Digital / Predix concept since it was a completely new product that desperately needed widespread adoption to be successful. You can't "transform" an industrial company into one that is at the forefront of software / "digital" with that approach. At least if they let their own teams / businesses use it with minimal friction, they'd have a much better shot at someone coming up with good applications for their product that they could potentially sell externally.

We no longer support .epub versions of our OpenStax books. Only a small percentage (around 1 percent) of OpenStax readers reported using the .epub format, and maintaing these versions is costly; instead, we focus on providing our online web view, PDF, iBooks, Amazon, and print versions.

One of the reasons is that the books are often used in printed format in classrooms and it's important that the page numbers of the ebook match what the teacher assigns from the printed copy.

With epub format the page # will vary depending on font size.

There's probably other reasons as well, but that's one that I've heard mentioned.

>> Folklore would have it that single-thread performance is the most important aspect of desktop performance

There are a few places where it matters. We talk of "gaming" but that is too broad a term imho. Many AAA games do leverage AMD chips well. They know how to split loads across threads to maximize performance. But in recent years the hot games have come from indi developers. Pre-release titles from tiny developers aren't properly optimized. If you want to play kerbal space program, single-thread performance is vital (KSP's physics is still single-threaded iirc). If you want to surf the web while running a factorio server, AMD will work fine. But if you want to maximize the performance of that factorio server, the faster single-thread performance of Intel chips would be better.
Hmm...is that one article in a series on ISAs, with this article the one on DEC. Or is it an article on ISAs, using DEC as the example?

You aren't disagreeing with me. Adding a location manually to a query makes it a different query, but I specifically stated one that doesn't have a location (and yes obviously users make such queries all the time!).

But yes, to your wider point, you can progressively delete all location sensitivity from every product and make them annoying and hard to use in the process. And even that wouldn't work. It's a fair bet that if you search for something with a location in the query, whether it be on web search or maps, that this is where you actually are.

The reality is nobody cares about this type of privacy feature, especially because Google can't avoid knowing at least your IP address. The AP only cares because it's gone digging for an attack story.
While I'm also not fond of the government side of surveillance, I think there is one major difference here for many people. And that is artificial creation of demand. Effective advertising can manipulate your wants and desires to convince you to desire things you really have no need or want of. And they go through every possible method to try to achieve this, including psychological manipulation. The reason I'm not fond of advertising is because I'm not arrogant enough to believe I'm immune to it. Collect enough data on me and you can probably create campaigns that would artificially push my interests towards things I would otherwise have 0 interest in.

When the government collects data on you the fundamental reason is to protect and grow itself, not to try to empty your wallet. Some of these data may end up getting, let's say, "leaked" and used for more self serving purposes by individual politicians or political parties, but that's at least a technically illegitimate use of the data, whereas such self-serving exploitative functions by corporations are the primary use of the data.
