W/ regard to space-based and airborne systems (commercial jets also actually operate in a fairly high radiation environment):

The risk of faults is not only non-zero, it's expected. Google 'single event upset' and 'nor flash soft error. Short version - (SEU) any bit in your RAM, CPU, peripherals, or databus can (and will, eventually) be randomly flipped in a high radiation environment. (Soft Error) - A random cell in your flash may be pushed into an indeterminate voltage range, and will return a different value every time you read it. So, for instance, you may CRC it, think it's good, copy it to RAM, and then the CRC of the RAM copy will fail because you got a different value the second time you read it.

There are ways to deal with this. Google 'lockstep CPU' for information on a common, fairly hardcore approach. Basically you replicate the CPU (and the rest of the hardware) and cross-check every single clock cycle; you essentially have two or more computers in one box doing the work of a single computer.

As you can imagine, this hardware is typically entirely custom, tested more thoroughly than anything you've ever imagined (unless you're in a safety critical industry yourself), and very expensive to design & test. Hardware refresh cycles are typically measured in decades, often governed by component obsolescence.
I noticed you left Twitter out, which is odd because it is the app that most closely resembles snapchat.

FB acquired Instagram for its user base.
Amazon acquired Twitch for its user base.
Google acquired Youtube for its user base.

How many snapchat users do you think also use those apps? How much additional value is being extracted from them via snapchat?
> It is really weird how we concentrate all sick people in one place, and then act surprised when they start growing weird diseases.

I don't think anyone finds it that surprising really. But healthcare is expensive and centralising in-patient care is the only practical and affordable system that we have come up with so far! Key things are to maximise hygiene and minimise length of stay :)
> drops all resolved CSS rules on element, its siblings, its parent and all children.

Browsers optimize this, too - they try hard to keep up metadata structures that tell them whether they need to invalidate styling or not. (This is why mutating the stylesheet is so expensive - browsers have to freshly rebuild the supporting data structures. They could optimize that too, but it's a lot of effort for a rare case.)

So if there's no rules mentioning an [a] attribute in the page, el.setAttribute("a", ...) will generally not do anything.

(One of the benefits of shadow DOM is that the shadow trees are scoped away from the main tree and each other, so you can have more expensive rules in them without making the rest of the page slow. Yay for componentization!)

I get your sentiment. I only started using Salt some months ago, but it was really a breath of fresh air compared to Puppet. However it took me a while to realize its true strengths since the documentation is very...dry.

IIRC Ansible, like Chef, does serial execution. That is, states are applied in the order they are written. I think that's part of the reason it has gotten so popular, as you'll have very few surprises in the vein of "what do you mean there is no ntp_service -- it's right there next to the config declaration!".

What Salt got right is the pillar, for which the Puppet equivalent (Hiera) was an afterthought. The Salt engine allows you to generate states from the pillar, rather than making poor clones of Puppet modules (as most of the formulas I've seen online).

However that flexibility is not documented anywhere, nor part of best practices. Nevertheless I'm about to release a set of formulas that are truly pillar-driven with no hard-coded stuff. Keep an eye out for the accompanying blog post :)

Of course, if you don't care about data/code separation and just want to get stuff done, there are better tools. And if you have full control of your environment, I would strongly suggest using Guix and/or Nix rather than these legacy configuration management tools.

After using systemd for a few years on arch linux I no longer despise it. It does have some good features like unifying system jobs and cron jobs, faster boot, journal forward secure sealing (to detect log tampering).

I don't like its effective ownership by redhat and its monolithic nature however this can be solved in the long run by forks and standardisation.
That's vaccines and there are regulatory issues in the US with them, antibiotics are perfectly profitable.

Also, only in the US does profitability seem to affect making basic medicines. Bacterial resistance is a global issue, not just one like vaccines that is largely a US issue.
It's an interesting feature but inetd (or xinetd) did it for a long time decoupled from the boot process.

A pro for systemd doing it is maybe consistent nomenclature for service startup, but a con is that it couples in yet another use case to systemd which may lead to a higher risk of security, maintainability problems down the line.

Interesting what the driver said, that he trusted the car after he'd seen the system stop 1,000 times. Self-driving systems put humans on lazy mode, where our guard is down that's why they should be fully capable. These systems should be thoroughly tested in real conditions before being released. It's incredibly irresponsible of Tesla to allow this ACKNOWLEGEDLY inadequate system to work in high speeds.
And yet, socket activation is nothing new:

Sure, but if they started issuing MitM certs ANYWHERE then Symantec would have no choice but to revoke the CA's certificate. It doesn't matter if the CA was functioning for a corrupt regime or a well-intentioned business legitimately MitM'ing employees traffic.

If Symantec didn't revoke the certificate then it would almost certainly lead to their root certificate being untrusted by major browsers and destroy their entire certificate business.
Thats is indeed pretty cool, the whole question is more under the way decisions are beeing taken regardless of what the community says.

But I don't really see what this sort of feature has to do in an init process. I really dislike the idea of having one project handling everything on a box .... The day you have a security issue in systemd we are all fu*.

But yeah there are some real good things in systemd, maybe they should just be taken out of it and spin up in a new project ;)

Proving that there's no better solution is impractical.

However, the size of the copyright-backed creative industries today, by any reasonable metric I can think of, is vastly greater than the size of the creative industries built around the alternative models that have been tried noticeably often so far. That seems to include all of volunteer-based, crowd-funded, mass donation-funded, traditional patronage where some wealthy benefactor funds an entire work, and pay-what-you-want models.

Likewise, the quality of work produced with the economic incentive of copyright tends to be better, often much better, than what is produced based on other funding models or a voluntary basis, particularly in areas that aren't things anyone is likely to do just for fun. (Some people may disagree, but I consider this point so obvious by now that it's rarely worth engaging on.)

That seems like decent evidence that no-one has found a reliably better way to incentivize creating and distributing new works so far, and it's readily falsifiable if anyone does in the future.

Patents are a different matter. I suspect the pros and cons vary significant from one field of research to another, with the general trend that patents might be useful in fields where the cost of R&D really is prohibitively high without some reliable way to exploit any successful projects, while patents are probably doing more harm than good in fields where they are more often used for sneaky legal manoeuvres than to incentivize genuinely innovative, widely useful, but expensive work.

This is cool, I've also been writing a similar emacs package: it uses `git grep` and `git ls-files` to quickly find patterns and file names in the current git repo, and has a simple interface for filtering the search results to narrow down to what you were looking for (and also uses a regexp heuristic for jumping to definitions).

I think this just reflects a combination of evolutionary psychology that was already there, the waning power of religious shame and shifting power dynamics. It seems mostly to be low empathy business badasses upgrading their partners. Whether it is men or women, that is more a personality type at this point than it is the domain of men anymore.

The End of the World
That article does not refute what I'm saying.

By the 1990s, affirmative action was already in full swing. Universities and large companies were already on board, as was the federal government and many state and local governments.

Additionally, by the 1990s, the national media had been very sympathetic to affirmative action policies for at least 20 years—you would have been hard-pressed to find a single American who didn't know those policies existed. So it was already perfectly reasonable (and expected) for a profit-seeking non-racist [1] to view black resumes with more suspicion.

[1]: And indeed, the studies mentioned in the article showed that blacks and whites exhibited the same bias toward black resumes.

Furthermore, regarding the studies mentioned in the article, there are some important question that need answering (by someone who has access):

1. To which employers did the subjects apply?

2. How were those employers selected?

3. Did any of those employers have pro-black affirmative action policies?

4. If the studies did include employers with pro-black affirmative action policies, how heavily were those employers represented in terms of applications? This is important: even if only 2% of employers have pro-black affirmative action policies (a number far too low), those employers might employ (directly or indirectly) 60% of Americans.
I thought this too back when I coded perl for a living. Still scratching my head over how PHP basically won that fight.
Yes I think that's more or less it. You can describe the entire mechanism of how an eye, optic nerve, and brain system sees the color green. In an ideal world you could explain that mechanism in absolutely detail, down to the molecule, down to the particle. Yet even if you did you would have said nothing about the most important thing about seeing the color green, which is the actual experience of doing so. That experience is what they call qualia. You can have the experience without actually seeing anything—you can dream it or imagine it, for example—which suggests that the experiencing is more fundamental, maybe more "real" in some sense, than the mechanism. Yet modern people, particularly of a scientific bent, have a dangerous tendency to emphasize the mechanism over the experience, even to the extent of denying the experience, and with it, the "person" part of people.
This just reinforces my belief that scale is a very solved problem.

It takes minimal effort to scale infrastructure these days, which is fantastic.

It also reinforces that there is nothing special about snapchat besides its user base, which is mirrored on half a dozen other social networks.

Yeah, that's why in our framework, we go the FastDOM /greensock route and encourage writing mutation code explicitly for when the state changes.

However to be fair the point of React, vdom, mithril etc. is to allow the developers to write a mapping from state to view and let the mutations be calculated automatically. They claim it's easier to just write the logic of the mapping instead of all possible transitions. I don't buy it, but it has grown to a huge community.

Building a school in a far off country without any prior experiencing in doing so is bad, but certainly not the same issue as trying to artificially increase diversity in the work place right? Quite different contexts.

I'm sorry that where you are seems like it doesn't deal with mental health very well (or at all, it sounds like). I'm from NZ and we have both very good gender equality (though not perfect, especially in tech) and very good support for those with health problems, psychological or otherwise (though again, not perfect - no government initiative can cover all scenarios and companies are fallible like anyone else).

Rather than arguing that gender problems shouldn't be addressed or should not receive as much focus, shouldn't you be arguing 'great, now can we also work on other areas of difficulty like ADHD?'

That's them. I had a look at these when it first was 'released' by Google, but back then it was more of an 'opt in' system I believe, with Google having to approve senders who were going to embed these schemas into their emails.

Have to revisit this now to see if they have relaxed the requirements a little. It will be good if these became a normal extension to all emails and other clients such as Outlook, Yahoo Mail etc. all pick it up as a standard.
I'm a computational neuroscientist (and data scientist and software engineer and startup founder).

The general principle in the brain is that the individual neurons (there are 25 billion in the cerebral cortex) represent statistically frequent occurrences of experienced phenomena. So if you know a lot about dogs and interact with dogs a lot, you will have a lot of neurons that "represent" different things about dogs (dog categories, dog behaviors, aspects of dog appearances, etc.).

The neurons "represent" perceptual experiences in a collective way called a population code. In one study on humans, a neuron was found that fired when viewing pictures of Jennifer Aniston but only when Brad Pitt was not in the photo. This does not mean the neuron had the sole job of representing Jennifer Aniston, but only that it was "tuned" to this perceptual occurrence. The tunings of neurons are distributed to "cover" in a statistical fashion the range and components of experiences. This particular human subject had perhaps watched many episodes of Friends.

What is still unknown is how the structure of a visual scene is represented. Neurons have been found for edges, contours, shapes, motion, depth, and objects. The mystery is how they all work together to parse and compose the scene. This is hard to determine because it is usually only possible to "listen" in on a few neurons at a time with electrodes, whereas it takes hundreds of millions to represent the visual world.

Regarding how visual mental imagery works, here is a post I made on Quora about that in case it is of interest:
https://www.quora.com/How-can-we-see-images-in-our-minds
Doing these things is also expensive in several ways. We have collectively decided that the cost/benefit is not worth it.

It's much easier to make antibiotics prescription only. Which we have. For humans at least.
This law suit is frivolous based on the assumption that APIs are not copyrightable (a very reasonable assumption in 2009).
One major advantage is that approaches like this just work, with zero configuration, and zero persistent state to be wrong. `git grep` (and ag) are very fast on modern laptops. That changes considerations dramatically from 10 or 20 years ago or whenever TAGS were introduced.
I find conversations on snapchat annoy me in the same way as conversations with a needy attention seeking girlfriend.

Yeah; co-working spaces or even a small individual office is usually $200-500/month, depending on the level of other services and location (in the Midwest).

I didn't focus on many of the other benefits, but one of my favorites is being able to work wherever I want, with a bunch of other people who are doing the same and provide a good dose of geographical/cultural diversity!

It is. The wealth of images alone, the sheer amount, from memes to vacation pics is worth so much now that image recognition is taking off.
Company, running privately for years and years, marginally cash flow positive but requires additional capital to expand, or develop the next product, or build inventory. Employees get refresher grants annually with an ever increasing strike price from .10 - 3.50 over say 8 years. Now during the road show the bankers say "You're company is really worth about 1/10th what you think its worth according to this feedback, we either cut off the roadshow or we recaptialize at a lower valuation." So the company does a 50:1 reverse stock split to get its outstanding stock numbers in line with the expected valuation of the company.

I'm not an accountant, but I've listened to a lot of accountants explain what is, and what is not, taxable. In this case, if you let your employees take a haircut (so their $1/share strike price is now $50 a share on a company expected to go out at $18) that isn't taxable (and it bites to be an employee). If your employee exercised their shares at the lower cost (to avoid capital gains etc) they now have a 'basis' value of $50 a share so if they sell shares at $18 the can claim a $32 / share capital loss. If you take back the vested but unexercised shares and issue vested shares at a new lower price, that price can be no lower than the pending IPO price (FMV) or it's a taxable event. And then when your company makes it out the gate and your long suffering investors cash out their funds, it pushes the price down around $8 once again putting your employees in a position to exercise at a loss or leave them on the table.

The key though is the company went through a period higher valuation, and employees are issued shares at the higher valuation and at IPO time the company is worth less than it was when you got your option, so your strike price is "high" relative to the company value.
This seems to be a common story. Systemd breaks one thing, but it's okay, they have their own built-in thing.
