had at least one water sample that measured at or above the EPA safety limit of 70 parts per trillion (ng/L)

Just as a comparison, the EPA safety limits for other compounds in drinking water is[1]:

Arsenic 10,000 parts per trillion

Cyanide 200,000 parts per trillion

Carbon tetrachloride 5,000 parts per trillion

All of those compounds are known to be very toxic. I'm curious why the safety limit is so low for these PFAs if there isn't much data on them.

I do not believe quantum computers can solve NP hard problems in polynomial time. According to https://en.wikipedia.org/wiki/BQP#Relationship_to_other_comp... , "The relation between BQP and NP is not known."

("BQP (bounded error quantum polynomial time) is the class of decision problems solvable by a quantum computer in polynomial time, with an error probability of at most 1/3 for all instances.")
Not related, but I had a hierarchy for grade happiness as a kid. 19/20 was superior to both 18/20 and 20/20. 17/20 was better than 16/20 and 18/20.

19 looked sophisticated, a calm mature lion or an eagle flying high. 17 looked like a very sharp shark or a young powerful wolf.
Dirty tricks are almost never worth the long term technical debt they represent when either (1) weird bugs start showing up or (2) the original author leaves the company.

I used to believe that there were times when dirty tricks were the right call in certain cases. The problem was that the long term view always proved me wrong: a more verbose but commonly understood approach is much more maintainable than a concise dirty trick, even with ample commenting and documentation.

Science publishing needs to be coordinated by the major funding agencies. Those who give the money are the rightful ones to say how the output gets disseminated.

I could not disagree more. Even if funding agencies were unbiased, they should be independent of where and how the results of research are disseminated. Funding agencies don't own that money, they only re-distribute tax-payer money. So it's tax-payers who have the final say (through elected officials).

If they want to make their own journals and stipulate that I publish there to keep my funding I'm totally cool with it.

This might create dangerous isolation and conflict of interests. The editors must be independent of the funding agencies to ensure quality of the research

The funding agency and general population gets its research, I get my tenure, and the university gets its money and prestige. It's a win-win all around.

The general population would get the research that was steered by a small group of people from funding agencies (DARPA, NSF), so possibly biased by the people on the agencies' committees and the government. I get my tenure if the tenure committee is aligned with the funding agency's guidelines; the university lowers prestige as the results appear lower-quality in an international settings. It's a lose-lose-lose, humankind's knowledge losing the most.

I don't even want to think about private funding agencies commissioning an article on their own journals to further their own economical interests, especially if said journals become the state of the art because other, better journals who would deserve to get the research published on them end up without submissions.

Sorry, but I don't see any scenario worse than this.

> It's constantly being updated, claimed guarantees regarding compatibility notwithstanding.

Updated does not mean incompatible. And the community bears this out, in the survey, most people had things Just Work, and for those that had issues, they said the upgrade was incredibly minor.

If there's something different than this, I'd love to hear about it: we care deeply about stability.
Better tenants. And there is competition for high-income tenants, particularly areas like Capitol Hill which are gentrified. Most people don't want to pay $2,100 a month for a 1bd, but the ones who do are worth getting in the door and generally work for tech companies.

Example - I didn't have to pay a security deposit for my last place due to working at Microsoft. It didn't really impact my decision to live there, but it might have if there was competition in their price range.
Anything that is public health related is bound to be full of tradeoffs and "good enoughs". The water in Flint, MI was considered good enough by Flint's officials, as is the water in many other municipalities.

Just as a private monopoly would start to reduce quality once it cornered the market, public, regulated monopolies behave similarly. Why care about quality if there is no competition and it's just another year earning a pension for the bureaucrats involved?

Consider how the bidding process for building roads results in poorly built roads and no incentive to the winner of the contract to build something that will last. Nearly every piece of American infrastructure is riddled with corruption or incompetence (or both). Even basic construction is full of various rules intended to bolster union workers, etc. and adding enormous cost.

The fact that Intel put an encryption feature in their chip, which does indeed make that algorithm faster, would tend to indicate they wanted faster encryption wouldn't it? That some other algorithm could be faster still isn't really contradicting that.
TLDR: a doctor thought he had ALS though he actually had a harmless (and poorly understood) condition called benign fasciculation disorder.

slightly off topic - Marc mentions he flies from Geneva to Amsterdam on Monday and vice versa on Friday and Craig's reaction to that seem to be of amazement. I am not from the continent obviously so I looked up the flight times and saw the total flight time was.. only 1.5 hours! Is that not normal and considered too long in Europe?

I ask because in Australia, that's roughly the same flight time from Sydney <-> Melbourne and a gazillion people take that route on a daily basis [1] plus it is considered a pretty short flight (try flying to Perth or Brisbane). At one point of my consulting career, I found myself flying to Sydney from Melbourne constantly every week for 6 months and at times, I just make it a day trip and take the first flight out in the wee hours in the morning and come back later in the evening. Mention it to anyone in Australia and no one will bat an eye!

I'm not so sure about that. The distance between the two locations is ~.25% of the distance from the Earth's surface to the moon, while one meter is only 0.000016% of the Earth's radius. So if the moon were on the side of the Earth such that it were closer to one of the locations than the other it would probably matter.

I found this SIGCHI paper from Google to be an interesting read. Abstract:

>The number of APIs produced by Google’s various business
units grew at an astounding rate over the last decade,
the result of which was a user experience containing wild
inconsistencies and usability problems. There was no single
issue that dominated the usability problems; rather,
users suffered a death from a thousand papercuts. A lightweight,
scalable, distributed design review process was put into
place that has improved our APIs and the efficacy of our
many API designers. Challenges remain, but the API design
reviews at scale program has started successfully.

I've been vegetarian for almost three years now, and the banana has become even more important to me than when I used to slice them up as a kid and put them in my Corn Flakes back in Brooklyn (yeah, no 5-grain, fair-trade, grown by native peoples cereals when I was a kid!).

Now, I live in East Java, Indonesia, and I eat the bananas right outside, which are a plantain. I am amazed out how quickly the plant regrows and produces fruit. I never knew they were a berry.

Indonesian bananas just gained tariff-free import to Japan last year to compete with the likes of Dole, Chiquita, and others. Fortunately, Indonesia has many varieties still being grown in case the TR-4 fungus hits harder than it already has. The Philippines has lost many plantations.

I personally prefer the smaller, less popular banana here for its taste. Maybe all those years of eating Cavendish bananas wore out my taste buds.

I do think the GMO crowd will step in, since obviously they can't wait to hybridize a local banana to scale up production to meet demand.
I really want to be respectful here but your comment shows a large level of ignorance around the difference between public monopolies, public UTILITIES, public (regulated) goods, and the economics thereof. A lot of public utilities were created specifically to enforce a level of quality and compliance and protect the citizen. In situations where the quality of goods is reduced below a safe level, you should not blame lack of competition, but call it what it is: incompetence at best, corruption at worst.

Good book on the topic that HN readers will appreciate is "The Master Switch": https://www.amazon.ca/Master-Switch-Rise-Information-Empires...
I dunno, maybe because you'll rot in a prison cell? I'm going to need something better than this for the 'competition fixes everything' argument. Yes, corruption in public utilities/institution is a serious problem. However I think you need to quantify that before breezily saying there is no difference between public and private monopolies. Private firms generally have far less internal accountability as far as I can see, and make the argument that loyalty to shareholders trumps obligations to customers.
The goal is not to boost productivity but to boost GDP growth of which productivity growth is one component. A larger population, all other things being equal, leads to more GDP growth. All things are not equal when you compare India and US, so that comparison is not relevant. Compare US with current number of people vs US with 10 times fewer people. Which one is better ?

I thought about this for a moment and then remembered something important. The big driver of our economy today is to add a layer of customization and modularity to existing processes via IT: Now you can get ala carte information, or summon a cab from anywhere, plan and present social arrangements with a minimum of formal overhead, or manufacture goods in smaller runs than before. Physical processes like transportation increasingly fit into a packet switching analogy - not driven by a particular modality of capital and energy(bike, car, train, plane), but by protocols driving end-to-end connectivity, like shipping containers.

This is not a process that creates value in the same way that using energy more intensively, to spin wheels, lift objects, melt iron, or process chemicals, grows value. In past iterations, we've always had a link between energy intensity and industrial growth.

But now we have a huge demand for new designs that reconsider the same processes, using a similar amount or less energy than before. The amount of labor that can go into designing that stuff is similarly huge. But it's a superstar situation - a few people make big breakthroughs by chance. We are "less" productive on average, routine work doesn't reap the benefits, and capital allocation doesn't have the guarantee of power it used to, in a world where tiny software startups are constantly scanning for a new platform lock-in opportunity. The economy stumbles from one speculative bubble to the next, trying to resume a paradigm of the past. It's a very chaotic, disruption-heavy, what-have-you-done-for-me-lately future that we've built for ourselves, and it's made everyone a little more insecure even as it produces its share of new wonders.
I agree there's a lot of (potentially dangerous) ambiguity in what the name "autopilot" means and implies.

Personally, I'm not a fan of the name "autopilot" for 2 reasons.

Firstly, the name is sexy and filled with hype. Even for a fully autonomous "driver go to sleep" level 4 driving system, "autopilot" would be a great sounding name (much better than "full autonomy" or anything more explicit in my opinion).

Secondly, the name deviates from industry semi-standard naming such as "cruise control" or "lane assist". I don't believe Tesla's automated features are more advanced than the rest of the industry[0], but the name sounds more advanced. Maybe this is good marketing, maybe this is dangerous and deceitful, maybe both.

[0] I'm not an expert on the state of self-driving systems. If anyone here who is reads this and has some evidence that Tesla's autopilot features are more advanced that what's offered by Audi (for example), I'd love to hear why / see some sources.

Set Default Font for Rendering Spreadsheets to Image and HTML Format in .NET Apps
Aspose.Cells for .NET 8.9.0 provides the ability to set default font while rendering spreadsheet to images as well as rendering spreadsheet to HTML. It also imposes Excel 2003 restrictions while refreshing Pivot tables. There are some important enhancements part of this release, such as expanding text from right to left while exporting spreadsheets to HTML, get the Release or Running Version of Aspose.Cells.GridWeb and add or Remove Context Menu Items in Aspose.Cells.GridWeb. We have handled a few exceptions regarding reading and writing Excel and HTML file formats. We have also handled an exception when calling Autofit operation on a worksheet. In this release, several important issues have been addressed. For example, issues around reading and writing Microsoft Excel file formats, copying worksheets, manipulating PivotTables, adding List Objects/Tables, converting spreadsheets to HTML files and vice versa, manipulating and rendering charts and shapes, rendering images from Excel worksheets, rendering images files from charts and exporting Excel workbooks to PDF format have been resolved. We have also enhanced the Aspose.Cells’ formula calculation engine and fixed a few issues in this regard.

This is where ideology has a role: in absence of immediate threats (which cannot be introduced everywhere), you do your job well not because you benefit directly, but because it benefits $cause. Public services without a public-service ethic don't work well, and public-service ethic needs some sort of ideological system to build on -- be that a religion or something else.
The author states that autopilot made him a better driver but I can't see how.

If the car is doing most of the work that requires a person's attention then they will pay attention to something else.

This will prove fatal when the sensors fail or there is some unforeseen condition.

Hunans are, at this point, able to detect and possibly correct for for more errors. Sure the car would be able to react more quickly but maybe it won't react at all.

> Every part of this statement is alarming.

The document itself is creepy as fuck. Have you seen the bspatch exploit and its comments? I've dabbled with iOS multimedia, and I know browser/JIT exploits get pretty complex, but this really takes the fucking piss. The unknown authorship and the fact that someone probably spent weeks to detonate a nuclear device against the software equivalent of a tree house in full seriousness and with no sense of absurdity is chilling.

Besides that, how many exploit coders in the public sphere even bother with FBSD nowadays? It just doesn't attract much interest from them, with everybody doing Windows, Mac, Linux, and mobile. Yet to someone this mattered a great deal. The jemalloc stuff could be skill-transferred from Firefox exploitation, though the exploit delves into compression routines and stdio internals as well.

Pit that against the "everybody calm down" complacency of the average Linux developer/fanboy, and you know they don't stand a chance. I haven't looked at Linux package managers in detail, but I can see them getting completely ass-raped at the "non-cryptanalytic" level in all their bloat.

Fact is, the open-source community is simply not paranoid enough to defend against nation-state talent.

And no offense to the FBSD secteam--I've doubtless made many more coding blunders than all of them put together--but I couldn't help but laugh at this:

"After discussion with the author of bspatch (Colin Percival, a former FreeBSD Security Officer himself"

It's a completely unnecessary detail, seemingly added for reasons of pride, but having the opposite effect from that intended, with no sense of irony. :-)
It was mentioned as a criterion. Actually, multiple:

- "Perfect IDE support" when described hinges on types
- "Static Optimizability" specifically mentions enjoying
type-driven AOT optimizations
- "Solving Real Problems" mentions types in the
"Refactoring is Painful", "'Non-trivial' abstractions",
and, briefly, in "Scala.js Solves Real Problems"

Furthermore, all of OpalRuby, Python, and CoffeeScript were explicitly dinged on their failures to have statically analyzed types.

But yeah, it does feel like he didn't give ClojureScript as much examination.
He's probably not shocked by the distance, but rather the lifestyle of living in two places, one for work and one for your family.
Keep in mind too that this argument chains - if your 2FA can be disabled with access to your phone/SMS, and your phone account can be updated with an email challenge response (or just a confident voice-call to your carrier's customer service), it's just one extra level of hoop-jumping for your attacker.
That's just part of the story. Productivity = value(p.output) / value(p.input) for all p in the economy.

So essentially how do you raise productivity ? Make ridiculous profits. Reducing the time it takes to do something, IF it results in more being done, certainly raises productivity but it isn't the whole story.

Currently the problem seems to be overcapacity pushing down on margins, with the situation being confused by central banks non-printing ("loaning")

between scare quotes because the prospect of those loans getting paid back are certainly not what they should be.

> A lot of public utilities were created specifically to enforce a level of quality and compliance and protect the citizen

Calling others ignorant does not help an argument. I think he had a point that when you let government control something it is the worst kind of monopoly and the quality is bound go down the drain. Whether it VA affairs, public education or IRS.

Excellent point. This misconception is also the root of silly statements like "human intelligence is uncomputable because we can do things like tell whether a program will halt." No, we can solve specific cases of the halting problem, we can't solve the general case any more than a computer can.
