Education as entertainment means that the goal is to get the consumer to feel good about himself, to feel like he learned something. You're getting paid (in money or kudos or whatever) to engage the consumer's narcissism, not his curiosity.

This is a profound observation. I’m not sure it only applies in entertainment.

I’ve heard it put other ways, but your version, if applied to education as a whole, might be a pretty big deal. There’s no shortage of evidence, either; from Ivy League campuses to niche interest subcultures.

Maybe “narcissism” isn’t the best word, but some sort of similar tension related to confidence seems to be associated with successful educational environments. We commonly attribute it to a one-way causal relationship, but you’re articulating the opposite. Likewise, we are used to acknowledging that ‘not giving up’, or ‘belief in one’s self’ is a necessity, but again you’re making a separate claim.

You’re saying, in so many words, the confidence in and of itself defines the will as well as the curiosity. And I can’t argue with it. I want to, but I’m not sure I can.
Well, data will be lost if anything below the OS buffer cache crashes (source http://sqlite.1065341.n5.nabble.com/How-dangerous-is-PRAGMA-...).

The BBU protects from power loss of the HDs, but not power loss or general failure of the mainboard or any other important component.

PAlso BBUs can run out of battery so a flash backed BBU is generally recommended.
It seems like they've chosen to not lay power lines down the length, which simplifies some things and allows them to reduce the tunnel size. But limits their drivetrains to only short bursts of use before needing to be recharged.
I so seldom think at this level I had a couple questions about the following passage that I'm hoping someone could answer:

>"The transistor can be viewed as a switch, allowing current to flow between two diffusion regions called the source and drain. The transistor is controlled by the gate, made of a special type of silicon called polysilicon. A high signal voltage on the gate lets current flow between the source and drain, while a low signal voltage blocks current flow."

If current flows from the source to the drain, is the source terminal hardwired to the power rail and always receiving some nominal voltage? Also does the voltage applied to the gate in order to turn the switch on come from the drain of a neighboring transistor? Basically wired in a series?

I always see MOSFET transistors depicted in isolation and then the conventional logic gate shapes used when depicting specific circuits like adder, mux etc. I find it tough to visualize how the gate, source and drain terminals in transistors as they are depicted in this picture physically interconnect to form the logic gate. Is there a separate metal layer for each of source, gate, drain and ground?
Seems like a crowd favorite, previous discussions here:

Look up UCS-2 that I mentioned in my comment.
I think what we call the skill of "analysis" is to divide an abstract object into a set of its containing elements, and then differentiate those elements and treat each element for its own different case.

China is one such abstract object...It's never about pro-china or anti-china -- after all it is a society of 1 billion individuals who are all differentiable from each other (and we have to differentiate a random chinese people from their government)...if we find a certain aspect of China appealing and potentially benecial to our own society, then why not just "like" that aspect and learn from them?

In the last few decades of the 5th century BC, Sparta and Athens fought a war with each other, which Athens had lost...but this did not prevent Plato (who was an Athenian) from praising certain aspects of Spartan society.
It's more of a guess than a conclusion. Because the tunnel is linear, the failure of a single skate affects the entire line, so running, say, 100 skates concurrently would make overall failure 100 times more likely.

One option is to make the skates incredibly fault-tolerant, but that seems to go against the simple / cheap ethos that this system seems to be going for.

You're lucky - Amazon actually give a shit about the US.

They launched in Australia (the newspapers were predicting the end of retail). They have what, 30% of products available here? Then they launched Prime - except they obviously haven't hired anyone who has used Australia Post before. You can't expect a Prime 2 day delivery if you use standard Post.

All this, and they thought restricting access to the US version was a good idea.

The Matrix Trilogy, IMO, is highly underrated. The 'action' (and lack thereof in parts 2 & 3) really distracted people from understanding what the whole thing was about. And of course, because of its age, I meet many people who've never seen any of the films. Oh well, I guess.
Yeah, it gets 5% of people home faster.

Why is Amazon expanding into brick and mortar with Whole Foods and now Landmark? Have they really saturated and squeezed all they can out of digital?

I like Apple's strategy better of sitting on piles of cash until they know what to do with it.

UTF-16 has a limit on the size of a code point because a code point is either a single normal code unit or a pair of surrogate code units, each encoding 10 bits of the code point (I think I used the right terminology). UTF-8 has a natural extension path to up to 7-byte encodings with all the usual UTF-8 properties (first code unit indicates how many remain, other code units are recognizable as not the first).
Isn't that what Netflix/Amazon Prime Video are doing? Aren't they owning the distribution of their in-house produced shows?

It's really not a question of not having a taste for it, or not being able to develop it. I'm 100% certain I could develop it, as my grandmother has -- due to seemingly inherent interest -- consumed ever spicier dishes.

My father, uncle, and I have no interest in developing our taste buds to consume ever spicier foods in the way my mother's family does. I simply am happy to eat whatever. So many things taste good, there is no reason to eat incredibly spicy food. That being said, half of my spice tolerance (which is incredibly incredibly high) is due to being forced to consume it by my mother.

Two main questions:

* How did you learn ESXi? Coming from VirtualBox/VMWare/Hyper V (Windows 10) the learning curve seems very, very steep.
Nice article but is it deliberate that you don't mention getting data into the database (line protocol or similar) or analysing the results and displaying them.

Input = use postGres
Output = Grafana has a postGres data source which I assume works and mention in timescales b's issues of a Grafana query helper.

Also lack of analysis, consolidation (continuous queries) and retention policies.

I am however intrigued as it does seem to hit my sweet spot of 100's of servers each with 5 to 10 different series of 10 metrics each, every 10 sec.

Database size might be an issue, as would the complexity of deployment (a big win for Prometheus rather than influxdb though).

Final thoughts
Can't help feeling this looks like a few input scripts running on postGres rather than a system solution for metrics and annotations.

There isn't a drop of evidence that staying in the same school would have prevented this. Claiming "this was preventable" and then tying it to your pet political cause is gross.

I know someone personally that attempted suicide in high-school while staying in the same social class and not having anyone cheat on him. I know several army brats that had no depression problems at all despite their social life resetting several times throughout childhood.

The way to prevent suicide is to look for the signs of depression. It's not identifying one upsetting event in a victim's life and then trying to reshape society to avoid that class of upsetting event.

Shall we make cheating illegal too?
Yes, they are. But that is because it is a new distribution channel that hasn't yet met controversy. I believe producers will be forced to divest distribution once again within the next 5-10 years, whether theatres or digital.
"Not allowed" by whom? Industry practice? At this point with the modern distracted, over-stimulated consumer, I would assume that these sorts of gentlemen's agreements are headed out the window

Also there are multiple examples of production companies owning their distributors which predate Netflix - think Disney and Buena Vista

From the link:

Tunnels, when designed properly, are known to be one of the safest places to be during an earthquake. From a structural safety standpoint, the tunnel moves uniformly with the ground, in contrast to surface structures. Additionally, a large amount of earthquake damage is caused by falling debris, which does not apply inside tunnels. Some examples:

1994 Northridge Earthquake: no damage to LA Subway tunnels

1989 Loma Prieta (Northern California) Earthquake: no damage to tunnels, which were then used to transport rescue personnel

1985 Mexico City Earthquake: no damage to tunnels, which were then used to transport rescue personnel

Absolutely. And this isn't a hypothetical.

> Yet even for those who have escaped China, surveillance and intimidation have followed. As part of a massive campaign to monitor and intimidate its ethnic minorities no matter where they are, Chinese authorities are creating a global registry of Uighurs who live outside of China, threatening to detain their relatives if they do not provide personal and identifying information to Chinese police. This campaign is now reaching even Uighurs who live in the United States.

Hmm... Yes we have large amounts of hydro, some geothermal and some wind but we use coal to supply the peaks.

The missing piece seems to be network level storage so usage times can be decoupled from generation times.

There is also the problem that hydro is not recognised as renewable. At least as far as carbon credits go. NZ landed in hot water after that was announced. We expected to come out in a good position on carbon trading, that was not the case.

I've always been amazed at how at the epicenter of a large city or event there are many normal looking things that contribute subtly or inadvertently to the overall awe. It's not like everything in Times Square is magical, yet the sum of them is.

I wonder how many of these more ordinary objects or store fronts you could remove and still keep the aesthetic wonder of the place. Take out the garbage cans, the street lights, the cross walks, bring the buildings a little closer together or father apart. At what point does it's quality simply change?

I'm still figuring out the microcode. It looks like about 4K x 16 bits.

The functional units are arranged with the 64-bit mantissa datapath at the bottom and the 16-bit exponent on top. The mantissa functional units have the constants at the left, then the bidirectional shifter, then the ALU, then a 2-bit and 1-bit shifter (for multiplication, etc), then three temporary registers, then register buffers and finally the 8 stack registers. The most significant bit is at the bottom. (Which is backwards to how it is stored with the most significant bit next to the exponent.)

You are correct that above the 8087 logo (to the left and a fair bit to the right) is a shifter. Above is a 0-8 bit shifter and to the right is 0/8/16/.../64 bit shifter. Combined, they allow any bit shift. It's bidirectional (with buffers/drivers on both sides), so you put the bits through one way to shift left and the other way to shift right. (Shifting is a big part of floating point. For instance, to add or subtract, you need to shift the numbers so the decimal points line up. And then you need to shift the results to be normalized.)

As far as layers: The bottom is silicon and doped silicon. The polysilicon for wiring / gates is above. On top is a single layer of metal. The metal and polysilicon are used for routing. Typically metal is mostly vertical and polysilicon is mostly horizontal or vice versa, but there are lots of exceptions. Metal is preferred for long routes (and power) because it has much lower resistance.
After elections individual congressmen become completely invisible to nearly all of the voting public. How many voters could tell you just 5 things, positive or negative, that their congressman did during their last term? People who know nothing about what they're voting on don't suddenly become actively involved after voting.

The only reason people care about the president is because he maintains a high visibility throughout his term. Even then it's very superficial. I'd be extremely surprised if the average voter could list 5 actual effected policy decisions of Obama that they liked/disliked. Yet they will love or loath him in spite of the lack of that knowledge. The various videos demonstrating this effect are my favorite. Individuals will be surveyed on what they think of described "Obama" policies, which are actually Trump policies - or vice versa. Their view on the policy invariably has little to nothing to do with the actual policy, and everything to do with the name attached to it.

Where are you getting this information though? I haven't worked out the bits myself yet but Wikipedia's first sentence itself says UTF-16 can encode all 1,112,064 valid code points of Unicode, which is already more than 2^(10+10) = 1,048,576.

Go errors out on unused imports, but you can type "import _ foo.com/unused-import" to not error out.

Why doesn't 'errors.New("asdf")' error out and require you to instead write '_ = errors.New("asdf")' to ignore the result

I think the real answer is not that it's intentional design, but rather that the original compiler was not powerful enough to implement that feature easily... and once go hit 1., it was impossible for them to add new warnings or errors because there are no warnings and errors are backwards incompatible.

Sure, that means developers use third-party tools for warnings because the go compiler refuses to ever have warnings (that compromises the pure beauty of the language obviously), but at least that means it's only the users that have to deal with the complexity of using more tools, the compiler developers can ignore it.

Fair point. I actually have an undergrad degree. I'm mostly arguing that as we have straightforward ways of addressing knowledge and ability via courses online (at a low cost to institutions), then admittance should be based on that ability rather than potentially dated proxies (college grades).
This might be a bit...too far out there, but could there be side channel attacks via cpu heating? Like heating the cpu to near borderline with AVX512 and seeing if a hyperthread causes throttling due to some “heavy” aes instruction. Sounds unlikely to be exploitable though.

Ever since specter I’m thinking of any performance changes by previous instructions might be exploitable. Again thermal throttling might be a bit too far out there since it’s not _that_ deterministic. Fun thought though!
