Lightedman's dead comment, in response to my, "The issue is that it's a lot easier to build or buy a kilovolt power supply that doesn't have adequate current limiting than one that does," said, "You can buy Van de Graaf generators all day long. Quarter-million volts minimum for $200."

While van de Graaff generators are indeed relatively affordable, and indeed some even cost less than US$200, a working microwave oven costs US$60, and a broken one can be had for under US$10. Furthermore, a safe van de Graaff generator is not actually capable of supplying enough current at the high voltage to operate a vacuum tube, while a deadly microwave-oven transformer is; and there are orders of magnitude more microwave ovens available.
A question I'm not equipped to answer but keeps coming up for me every time this conversation or user-space drivers comes up:

If we had microkernels, would containers be a thing right now? Or would we just have orchestration tools (eg, Kubernetes)?

I'm old enough to recall when protected memory and pre-emptive multitasking were the new kernel services and all of the literature for those greatly overlaps what we use to sell containers now. Like we never achieved the promise and we are trying again instead of fixing it.
Honest question. What is this demographic which will ride a scooter but don’t want to walk less than a mile. Just seems weird to me personally. I wouldn’t think twice about walking that far given infrastructure that supports scooters.
Crazy when apartments in the city have no parking and you have to factor in an additional $300/month for a parking space that might be a 10 minute walk from your apartment. It’s like US cities maybe aren’t actually the best in the world or something.
If my cloud provider is bad, I can switch to another one or self-host.

You can't switch from the ICANN, no matter which domain you chose, it depends on them, they effectively have a monopoly. I want to self host my domain name.

What a coincidence! During the hard freeze on New Year's Eve here in Austin, TX, I discovered a field of this stuff in my back yard. When I first saw it, I didn't even recognize it as ice! It looked more like a fungus at first, and only after touching it and seeing that it was dissolving did I realize what it was. After some Googling, I came across this exact Wikipedia article (thanks Wikipedia!).

I think AST did. IMHO, drivers belong in user space. There's an exponential number of devices out there, jamming them into the kernel has been a messy chore at best.

Yeah, I came here to post that "last flamefest" part. Oh Linus, it certainly won't be your last...
Hey, I was also at Demuxed last year! I help maintain Hls.js; it should have some form of LHLS support by soon(tm). There's no standard yet so actual adoption will be tough (current implementations use non-standard EXT-X tags to signal LHLS). But pretty much everyone does the same thing: early signaling of segments, chunked transfers, and on the client side, progressive demuxing. HTTP-based solutions typically achieve the aforementioned 3 seconds, but anyone talking about LHLS now (Akamai and Wowza) have their own protocols; it remains to be seen what the rest of us will get.

Twitch has recently implemented LHLS (looks like a "periscope-style" implementation) and I was seeing 1.2s glass-to-glass.
Here's an anecdote about my experience at a mall yesterday. I needed some new shoes:

I went to the Skechers store. There were 4 people working. Not a single one ever offered to help me. I had to walk up to the counter and the girl looked shocked when I asked her to get me my size to try on. She handed me the box and walked away. I never saw her again and walked out without making a purchase.

I went over to Macy's to the men's shoe section. The section was about 5x the size of the Skechers store. There was one person working who was busy with a customer at the checkout. After waiting for 10+ minutes with no one to help, I left without ever trying on a pair of shoes.

Then I went to Ecco--they are a small shop with only a small number of shoes. While the salesperson was quite attentive and helped me out, the one pair of shoes they had in the store that were interesting to me didn't fit right so I left.

Tried to go to one more store only to discover that this particular location only carried women's shoes.

All told, this adventure had me in the mall for about 90 minutes and I had managed to try on 2 pairs of shoes. Throw in the drive and it was over 2 hours for nothing.

I went home, spent 20 minutes on Amazon Wardrobe, and I have 8 pairs of shoes in my size arriving at my house in a few days to try on.

Stores in a mall have a real opportunity to win on personal service and instant gratification. Hire someone to help me find shoes that fit me well and go with my own sense of style and who makes sure I go home happy. But if my choices are spend over 2 hours for nothing or go online, I'm choosing the latter every time.
It's fascinating that people think like this. Prices went up, so supply and demand don't work, and it's "speculators" that are to blame.
I'll have to check that one out. So far its been mostly using random videos off Youtube, would be nice to have something physical to look at quickly.
Open Street Maps have much more users (and thus better ground coverage) in Europe, e.g. Germany. I think that's why the experience may be diametrically different for different people.
That would only escalate the war. People would start out as an open source hardware project with minimal commits/docs and turn "evil" the moment they got assigned a code. Then they would have to account for that. War escalates again, go to step 1.
The set theory that most working mathematicians deal with is ZFC. In ZFC it is not known what cardinal the continuum is. Hence the statement that I was responding to is incorrect. The person I responded to said that they do know how many reals there are.

The cardinality of the reals is called c. It is known to the be the same as the cardinality of the power set of the naturals. It is not known, in ZFC, which aleph this is. We just know that it is the same as the size of another set.

If you want to add an axiom and say that c is aleph1 then you are free to do so. But if you don't have this axiom then you don't know which aleph it is. So in what sense can you say that you know how many reals there are? You only know it if you add an axiom that says, "It is aleph1."

If I have a jar of pennies and I know it has the same number of pennies as the number of quarters in another jar that I have, does this mean I know how many pennies are in the jar?
Think about validation like an iterative series of steps.

The first step (even before you have an idea preferably) is to identify who you want to serve. What target market are you going after?

I think it's wisest not to go after beginners. More about that here:
https://justinjackson.ca/beginners

Next, you need to observe your target market. What do they struggle with, that they'd be willing to pay for? What evidence do you have of this?

> the fetching of data will have to go deeper and deeper into the data store.

Facebook long ago mastered server-side performance for this sort of use case [1]. Minimizing the number of network requests a mobile app has to make (enter GraphQL) is more important than mitigating costly requests, especially on slow or unreliable networks where the bulk of time in spent waiting on bytes. Entire pages/screens can now be fetched in a single HTTPS request vs. multiple.

As an added bonus, it allows front-end engineers more autonomy and flexibility without having to involve back-end API changes to support ever-changing product updates.

I gotta say I love but am surprised by the public google doc of the outages. If I worked there I would personally advocate for not doing that, only because I feel like it would slow down resolution if I have to constantly be worrying about not putting "secret" things into the doc. Unless they have someone who's job is to take their real chat and transcribe it, in which case, that's great because that person is useful for a postmortem as well.

Speaking of postmortems, reading through the Google Doc of their outage timeline, my first postmortem question would be why is the website dependent on the database being up? Shouldn't there at least be a fallback that says "We're offline right now sorry" when the database is unavailable? Or in the name of extreme transparency, have it frame or show a link to the google doc of the outage?

My second question would be how often do we test failures of a read slave, of the master, and of pgbouncer? Do we at least have a practiced procedure for manual failover if not an automatic failover?

My third question would be what sort of alerts do we have, if any, on replication lag?

It's been a while since I've had to run a major outage, this was an interesting exercise for me!
It's not "extremely controversial". Minix was used as the platform Linus initially used to build Linux (for lack of a better name).
Yea exactly, there is only one problem it really solves, and it's already found it. Currency (and sure some stuff that touches it like smart contracts) is the one use case where all the blockchain's properties are useful. Everything else, just use a public/distributed cryptographic ledger, save yourself a ton of money. Use technology that's worked for 30 years.

Yep, be smart or take the single "warning letter" from your ISP.
Rudeness is inferred or "felt" by the other party, and really worrying about peoples feelings or emotions is like worrying about which direction the wind is going to blow today because emotions have the ability to be extremely irrational. Perceiving something as "rude" ultimately comes down to the individual who is being told the information as interpreting it as rude. In this case, anything can be viewed as "rude" under the right microscope -- in fact Linus has brought up this very point multiple times in a sort of a "individual liberty" light. If you take feelings out of it and focus on the information -- Linus is either right or wrong. Something either sucks or it does not suck, for example. We can talk about how he might be wrong -- maybe it doesn't suck here's point x y and z refuting his a b c on why foo system suck.

You can certainly choose not to converse with Linus, just like I choose not to converse with overtly politically correct people who may take offense / report little thing, I personally don't have time to worry about if what I said "might" come off as a certain way and really I wouldn't want to be in that situation anyways -- It is exhausting to always have to editorialize what you are going to say in today's hyper-sensititve-filter-bubble-one-worldview monocultures.
Yes, that's huge. The big numbers can look overwhelming. Huge land-use changes that we've already made would look overwhelming if considered as a single monolithic project. Solar facility construction isn't going to be a single monolithic project any more than the existing American biofuel or fossil fuel systems were.

http://farmdocdaily.illinois.edu/2016/04/corn-consumption-an...

2016 numbers: about 93.6 million acres planted for corn. About 5.2 billion bushels out of 14.4 billion bushels of corn yield went to corn ethanol. If harvest and land area are proportionate, that's about 33.7 million acres dedicated to corn ethanol [1].

33.7 million acres is about 136,000 km^2. The areal energy yield from biofuels is paltry compared to what you can get from solar PV. Manufacturing/installing solar PV is more resource-intense than planting corn. But it's low-maintenance once installed. It doesn't require arable land, weeding, irrigation, fertilizer, or harvesting.

[1] Yes, the residual material left after fermentation is also used as animal feed. But the conversion efficiency is low; you're not adding many calories per acre to the human food supply when corn is fermented and leftovers go to cattle.
I don't think this construction works, for the same reason that rationals are lower cardinality than reals.
I e, I think your program proves the rationals, not the reals.
Over 20 million lines of code even. But you only run 1.5 to 3 million.
Ironically enough the malls were envisioned to be that by the person who came up with the idea, the devil's bargain here was letting cars be the part of the equation.

Also I'm not sure about the egalitarianism of the millenials. Millenials shop at Amazon, and we've seen article after article reporting on deplorable ways the company in treats its workers.
> Employees aren't friends and really shouldn't be.

That's a fine view to take! But don't come rattling the cup around going "but poor founders, so lonely, nobody to talk to" when they've made that choice.
The author's paper is about normal numbers (numbers that contain infinite amount of information). If a normal number isn't considered to have random digits then what notion would you use?
> "Be thankful you are not my student. You would not get a high grade for such a design :-)"

It's really amazing to read and see all sorts of good points from both sides, and know that if it weren't for the benefit of hindsight, I'm not really sure which side I would agree with.

But I really strongly get the feeling that Andy had a great opportunity thrown into his lap, but by looking at MINIX as a "non-serious" hobby (as Linus implied) that he only did for fun and to unwind, and by not really listening to his user base (make it free, fix filesystem race conditions, add POSIX compatibility, etc), he really threw the opportunity away for it to grow. Which is fine if growth was never the goal.

And sure, a project owner doesn't have to say yes to every feature, and they actually probably shouldn't. But you have to let what you're creating evolve into something that meets needs, and turn into something different. Look at the first page of commits on Semantic-UI's repo. It was called Origami (then Shape) and was meant for doing 3D stuff in JS, before he renamed it to Semantic and turned it into a JS-based version of Bootstrap. Terrible example and doesn't really apply here but I remembered coming across that fascinating bunch of commits the other day and wanted to share it with someone.

> But there is no general law preventing increasing the precision with better instruments and better methods, so as measurement gets more advanced, more data (such as more decimal digits) can be obtained.

That's not true, as at the Planck length both quantum and general relativistic effects are equally important, preventing arbitrary measurements over smaller scales - that's the case even for a continuously-divisible universe.
In most quantum gravitational theories today the Planck length truly is a minimum possible distance in the same way the Planck time is the minimum possible duration, representing a quantized space-time with hard limits to the precision of measurements.
Time for another outage tshirt?
> they're all based on materialist consumerism... Libraries, Gyms, yoga centers, Cafes, Restaurants, movie theaters, science museums, bike repair shops, ceramic hobby shops and indoor swimming pools, theaters and historic museums

Aside from libraries and (some but certainly not all) museums, aren't all of these examples of things that fit well within materialist consumerism?

I also prefer yoga studios, expensive coffee, fancy restaurants to specialty knives, clothes shopping, shoe shopping, and food courts.

But those sorts of personal preferences are just matters of choosing what to consume, which doesn't seem like a fundamental or important difference.
> That is kind of frightening - why stop at school? Why not have Sweets Inspectors checking up on parents in their home? And talk about taking the fun out of any celebrations.

I see what you're saying, but considering the exploding rates of obesity for children in the U.S., maybe dialling down some of that "fun" is necessary. There is overwhelming evidence that overconsumption of sugar is very unhealthy and fits the profile for addiction. I started looking at sugar the way I look at alcohol: to be consumed in minimal amounts, if at all. If one takes that view, measures such as those in Norway don't seem that extreme anymore.
Two that come to mind are:

- Using data augmentation to turn the smaller amount of examples into enough samples for appropriate representation within the dataset.

- Add a weighting coefficient to the model's cost function to make misclassifying these examples more expensive.

Note: you can do serious harm to your model with either of these approaches if you don't know what you're doing. The safest solution is to collect more examples of the infrequent class.
Wow. The author of this paper should be awarded the Ig Nobel Prize for both math and physics :-)
I'm not sure this is a sign that the speed of business is really quickening all that much. VC-funded bubbles provide a local acceleration in business speed, but they also drastically increase risks and systemic waste.

It's also not clear to me that there will be "a winner" once the VC money runs out. There's no "a winner" in the convenience store market, for example. A study lists 202 viable convenience store chains, the smallest has over 30 stores. [1] And that ignores the many one-off chains, and some of the places like Walgreens and CVS that clearly substitute for convenience stores for many.

I stream a lot of sports from home. I would gladly trade delays for stream stability/quality. I frequently have to switch from a legal stream that I pay for to a more robust illegal stream.

It would be annoying if there were multiple devices nearby on different delays, but for me in my living room. I don't care if it's 30 seconds or 3 minutes. I've gotten spoiled by twitter feeds a few times, but it's not the end of the world.
A closer historical analogue to what Vice has tried to do is probably Rolling Stone. Today Rolling Stone is utterly dispensable, so it can be hard to imagine; but in the '70s it was what Vice so desperately wants to be today, a sort of journal-of-record for youth culture. If you wanted to know where the edge was, Rolling Stone had writers like Lester Bangs and Hunter S. Thompson who could show you.
It fits because I moved on from doing javascript, it was no use to me when all the chapters were finished. There was no compalint about the quality, yes it was excellent for the chapters i read.
It’s worth noting that Verisart is very similar to https://www.ascribe.io which preceded it. Though ascribe has focused their marketing more towards digital art.
My "firstname.com" and "first.in" (shorter version of my first-name and that is name I am actually known by pretty much everywhere) are both squatted by a lawyer and it is being renewed every year since last 10+ years. It's not being used. Not at all.

I tried to contact them but the contact email (Hotmail) probably doesn't exist or expired as my emails bounced off. I tried to contact the registrar but didn't receive any email from them either.

I am thinking of going for firstname.net. I am not sure whether it's better than my already registered "first.im".

Note: first as in if "firstname " is Michelangelo then " first" is Michel.

Han from Paladin here. We are really excited to launch our latest Chrome Extension and excited to get feedback from users like you.

Paladin was founded as a Cyber Protection company for SMBs. One of the products that we began building was a cyber protection tool suite for employers to give to their employees. The tool would help mitigate the risk of being hacked. We also provided remediation services, that was all backstopped by a cyber insurance policy. Our chrome extension was built with NSA level encryption and security measures, and we realized that we couldn’t just let this chrome extension hide behind a wall only for small businesses.

Once we had tested our chrome extension extensively, we decided to take our mission of making cyber protection easy for the little guy, and extend it to consumers by offering our Paladin Browser Protection for Chrome to the general consumer, free of charge.

As consumers and internet users we are often at risk of being hacked, even when we don’t necessarily realize it. Add to that the fact that most available tools out there are really only band-aids, incomplete, or act as medicine, we realized it was important to build a vaccine. Paladin Browser Protection for Chrome provides protection against the top 5 consumer vulnerabilities:

Weak passwords, unsecured public WiFi, phishing emails and website, unsafe content and XSS vulnerabilities and attacks.
Here’s a breakdown of the features and how they work:

- Password management -65% of people use a single password among all applications, so when one login is breached, they all will be. Setup a single sign-on password with our password manager and generate strong passwords for all of your logins.

- Phishing protection - 91% of successful hacking attempts start with phishing emails. With Paladin’s Browser Protection Chrome Extension we protect your inbox (compatible with Gmail and Outlook365) by calling out malicious attempts so you don’t get hacked.

- Unsecured WiFi protection - 68% of public and unsecured wifi users fall victim to an attack. We encrypt all your data before it goes to the router, then route it back through our servers, leaving you clear of any danger.

- Website and content filtering - 99% of known threats are blocked by our filter. The filter prevents you from accessing all phishing websites along with other unsafe sites

- Cross-site scripting protection - 50% of websites are affected by XSS vulnerability. A script attack allows a hacker to transfer malicious code right through a normally visited website. We stop them dead in their tracks and report back to Paladin and the authorities to take them down.

Explore the chrome extension, test it out, and let us know what you think. I’m here to answer your questions.
And this is how power hungry people/organizations throughout history have implemented disastrous policies in the interest of the "greater good".
