Yes, now we can also do
best L^1 approximations.
IIRC -- I'm in a hurry this
morning -- it's a linear
programming problem or
some such but I haven't
thought about that in
decades.

You bring up a lot of stuff
I've never reviewed.

> but that does not mean it is a suitable performance metric to use.

If the plane do the L^2 projection
on is really close, then the
error is really small, and what's
not to like? Really close is
good enough for me.

Right, there are three biggie
choices, L^1 (minimize the
sum of absolute values of the
errors), L^2 (minimize the sum
of squared errors), and L^infinity
(minimize the worst error).

L^2's fine with me, good enough
for government work, okay
first cut, day in and day out.

If in some particular case
L^2 has some problems, then
maybe something like regression
is not the right tool for the
problem.

Gee, we do a lot of L^2:
We get orthogonal components
so that we can get L^2
cafeteria style, just pick the
components we want.
E.g., in filtering stochastic
processes, we take a
Fourier transform -- that
is finding the coefficients
of the sample path on
the sine-cosine orthogonal
components. Or we
do a convolution, which
is the same thing in the
end. The approximation
we get is an L^2 approximation.

So, with JPG -- sure, it's L^2.
Right, JPG does funny stuff
nearly lines. Life's not
perfect!

For some things, sure we
want L^infinity: E.g.,
if we want to use a
quotient of polynomials
to approximate the
usual special functions,
then we want to minimize
the worst error and do
what is called Chebyshev
approximation, but this is
very specialized.
Maybe so, I'm not an expert on such matters, but the highest tax rate was 50% or higher from 1932-1986. I would say that is relevant to our current discussion.
The blockchain itself is for most cryptocurrencies already quantum-proof, since they rely on hashing blocks until some number of leading zeroes is met. That is the blockchain part.

What the paper seems to target is quantum-proof account management, a problem which atleast on the Ethereum blockchain is trivial to solve at the moment with some inconvenience and with later Hardforks implementing the account abstraction, will be part of how the chain works. Everyone can then just use a Lamport/Merkle signature, SIDH, New Hope, whatever, as long as it can be implemented on the EVM.

I'm not certain why we need to throw quantum-computing at the blockchain until some arbitrary amount sticks that can be declared "secure".
why do you think so? i don't have strong convictions either way, but i don't think i'd count it out as an impossibility.

Last year I learned that 20% of adults who were diagnosed with a peanut allergy outgrow it after childhood. It is worth getting tested again if you grew up with a peanut allergy.

I had signed up for a trial of one of these drugs. Having grown up in the 80s with a severe peanut allergy that required the use of the epipen more than a few times I was keen for anything that could help, even just something that would lessen the reaction so maybe I could choke down some benadryl rather than stabbing myself with that ~2 gauge (hyperbole) epipen that now costs a fortune.

First thing they did during the trial was give me two peanut tests, skin prick and blood test. Both came back negative despite positive results decades earlier as a child.

I would have never thought to get tested again on my own. Not being allergic has made such a huge difference in my life - I was always flippant about my allergy and had developed good safeguards to protect myself. But the amount of stress is caused me was amazing to have lifted. Hope that these drugs can bring that to others (or just get tested again and maybe you're one of the lucky ones!)
Well yes, but there's a string of WTFs here, lots of 'trivial' stuff that wasn't done!
The NYT, with advertisement slogans like "Truth. It has no alternatives." (When I first saw it, I had to double-check whether I am reading some English translation of one of the "Pravda" issues in the USSR -- no, it was still NYT), -- well, despite such bold claims, they often act as the principal venue for top-level PR firms. Increasingly so in the last few years -- I understand that newspaper business is in deep trouble, and I understand their envy to Facebook and Twitter, but this sounds just a teeny tiny bit unethical to me.
I never knew that peanut oil was used as a vaccine adjuvant.

What is interesting is that anecdotally in my experience and those I talked to the VIP patients in VIP rooms tend to have worse outcomes.

It may be because there is a tendency for VIP to demand that something be done and it not be uncomfortable. So they may go through more tests and procedures for every little complaint and maybe get more pain meds which ends up contributing to worse outcomes.

In addition, the doctor may be reluctant to say "no". For the ultimate example of this, see Michael Jackson.

Finally, teaching hospitals provide some of the best care in the country. So because of that, a VIP may go there. However, many of them don't want to be seen by residents and medical students and residents. They want to be seen by the famous department chair. Well, in many cases the department chair may be good at research and politics and fundraising, but may not be the best actual doctor. In addition, they may be years removed from actual day to day patient management, relying on the residents to manage the details. You can imagine how things can go wrong.
We give everyone access to production systems, but even if someone deleted everything from production, we can restore everything in ~20 minutes (this has happened), and if that process fails, we have backups on s3 that can be restored in a couple of hours (and this is tested regularly, but thankfully hasn't happened yet), and even if that fails...

There's a reason why it's called disaster recovery and prevention.
> Yeah, rollbacks are more of adding a revert to the top of the pile

Neat. It reminds me of the method used in gaming nowadays, which is to just write a "savepoint" marker in to the message stream instead of pausing the entire game to save state.

Although I do think some of these coins are here for the long term and their value in the long term will probably increase, there seems to be a hype cycle every now and then, when the price explodes and so do all the articles being written about those coins. And then an inevitable crash follows, and people stop caring about the coins for a while or start dismissing them, until another hype cycle appears.
I don't personally have a problem with people paying extra to receive what they perceive to better care.
But I think if you look at outcomes, I doubt you will find that they have received better care by paying the extra 40k or whatever it is a year. It's great that the kid in the story was able to be seen by a established orthopedist in a city hospital - but most general orthopedists know how to set a kids leg, and I doubt the outcome would have been much different if they had gone to the originally intended ER.

It's certainly a good gig for the family practitioner, but I think the following quote at the end of the article:

"“The traditional model of having a good internist is dying,” said Mr. Traina, a scion of a prominent family here that arrived with the California Gold Rush.

will apply to the concierge doc in the longer run as well. If you are reasonably healthy, checking your blood work once a year and your blood pressure every so often, you don't have much need for a family doc. If catastrophe strikes, then you will probably need a specialist - and if you're willing to spend the money, it's best to save it for these times - yes your cash will get you in as easily as a concierge doctor can - rather than dishing out 40k annually.

I recently chose a medical clinic that's part of a university system for my own healthcare, as opposed to a family doc who charges $1400 for an initial exam and $400 for follow ups. Do they spend as much time with me? No, I'm in quick and out quick. I get my shots and blood work and I'm out the door. Since I'm pretty healthy, that's the way I want it.
This goes for many things outside of cars. Insurances, Mortgates, student debt, lottery tickets, consumer debt, credit cards and so on.

In general people are sitting ducks when it comes to being fleeced by parties with a plan.

I always wonder why schools don't even teach the beginnings of finance to everybody. You'd almost think there is a reason why it explicitly is not being taught.
No disrespect to the OP but this sounds pretty fake. If the database in question was important enough to fire someone immediately over then there wouldn't have been the creds floating around on an onboarding pdf. And involving legal? Has anyone here heard of anything similar? I'm just 1 datapoint but I know I haven't.
The Amazon DevOp guy was fired for that mistake, just FYI.
I was angry when I posted this yesterday. My anger has dissipated a bit, but I haven't been able to stop thinking about this issue.

I think what might actually help this situation is a simple new regulation giving people the right to be notified when data about them is bought or sold including the name of both buyers and sellers and the data in question. If Google had to inform you when they sold your data we could at least be aware when we are being tracked and by whom. The current system where we blindly click "I agree" is broken. people do not want to wade through all the legalese and shouldn't have to. What they would be more likely to read is a simple csv containing every datapoint which was collected about them and to whom it was sold.

The whole "Don't be evil" thing, I believe, led to an expectation of Google to act in at least a responsible manner. Given the control they have over our lives it is time to start enabling us to verify the veracity of their claims.

If this was enacted, then I don't think people would mind ditching the ad blockers as much.

I don't know if Google is evil or not, but its looking scary as hell from over here.
In theory though, the market should address that right? e.g. a version of this that's $10k a year but can handle 10x the volume because you triage patients with competent nurses and PAs and save the expert's time for the cases where they can actually make a difference.
I wonder if it's like the difference between taking coach vs. a private jet. The private jet is more convenient and comfortable, but safety ratings are considerably better on major airlines.

That's probably what it is, accidents are more likely in general aviation but still rare, however if you must fly commercial you get to face the TSA perverts every single time you go through security.
You're right. And more importantly, the 'world's best cardiologist' won't remain that if he continues to treat mundane cases.
This is an attempt by Google to funnel more ad revenue and try and kick out competitors in one stroke.

It will only work partially.

As other commenters have said -- this doesn't go far enough though, which is understandable, they won't pull the rug under their own feet.

And no, users won't start uninstalling adblockers with happy smiles.

I guess for the huge scale Google operates in there will be slightly increased revenue for a while though.
that's pretty cool :)
lets assume for the sake of argument some of these platforms aren't scams/bullshit hype and actually add value in some way. like the prediction platforms augur or gnosis.

the main problem, i then see is that if these tokens are required to use the platform, wouldnt their cost be prohibitive? and the platform wont be useful?

these tokens are going up in value just like bitcoin which always had actual use (mostly on blackmarket) so their incentives are aligned with the token being used as a currency, but not as an app token that is required for the product.

so in effect, these are just over hyped quasi securities offerings and trading.
I am on the other side of the discourse (hopefully, not of the lamp post -- just yet), but I politely disagree. Why do you think the revolution (or even a civil war) is impossible these days?
China Agrees to Delay Quota for Electric and Hybrid Vehicles Until 2019
I'm plenty of aware of how people with assets are able to use them as collateral to borrow money, but this article has nothing to do with that kind of financing. It's about 72mo high interest loans on cheaper downmarket cars marketed to people who used to buy old junkers.
Where is eBook Interoperability?
Kotlin Native doesn't exist beyond pre-alpha software at this point, so the the question is a bit premature.

In 3-5 years Kotlin might be where Swift is now, but there's nothing guaranteed, just coming up with a GC solution alone is a gigantic engineering effort -- Kotlin, like Scala, Clojure, etc. all benefit from world class GCs, just by being hosted on the JVM. With LLVM you essentially start from scratch, same for porting Java libraries, there's a ton of work involved.

tl;dr; for now it's separate languages for iOS and Android unless you cut some corners with React Native to avoid writing the same app twice.

You missed one of the really nice points of having a stage there. You use it to test your backups by restoring from live every night/week. By doing that, you discourage developing on staging and you know for sure you have working backups!
A lot of reasons, but one solid one is that there is a pretty strong anti-pattern in that the ones that desire wealth redistribution the most are the most likely to support gun control and/or the banning of private ownership of weapons.
Looking at the Roman Republic, there was exactly one revolution in 500 years, led by the Elder Gracchus, and that wasn't successful. The Secession of the Plebeians came close (but is semi-legendary), greater success in the Conflict of Orders was had through working within the political system and all of this (Twelve Tables, opening of high office to plebeians) happened in the early republic.
Yeah, I thought it sounded fake as well. I mean things like this happen, but something about the story just doesn't ring true to me.
My answer would be "heaps of times". Different currency (GBP not USD) but still I saw £20s and £10s a lot
David Blaine Interview on Fear{less} with Tim Ferriss
Maybe I didn't understand the deal I bought a car with, or maybe it's an unusual deal, but I'm happy with it.

My car costs me a set amount per month that I can afford, an amount that is actually equal to the monthly depreciation it would face anyway (on average) over a three year period (including the initial low value deposit I paid, this is still true).

Even if I bought it outright, which I couldn't afford to do, I'd 'lose' the same amount of money _in total_ thanks to that depreciation. Effectively I'm 'renting' the car for the same 'cost' as owning it, just without the upfront payment.

Further, GAP insurance purchased at a one off price of about £100 (which was far more tricky to make sure I got the correct thing) will cover any difference in the 'hand back' price at the end of my term and the value of the final payment. So basically if the car does depreciate below the value of the final payment then the GAP insurance will make up the difference. Likewise if I have an accident etc.

I reject the idea that PCP deals are like 'buying and selling a series of homes using interest-only mortgages'. Cars lose value, always. Whether you buy it outright or not, it'll depreciate in value (save for some hyper rare beasts you aren't going to be buying on PCP anyway). But the article doesn't address this point at all as far as I can see and it's an important part of the value proposition of using these types of deal.
It is the most rational model. Unfortunately, like mentioned in other threads here, fully private, cash-to-hands medical practice is prohibited in many countries.

I have to travel to Spain for my medical tourism needs. However, it is mighty inconvenient.
Adding external APIs triggered by key phrases is just plain old programming. The fact that a multi-billion dollar company could not solve this basic programming problem to make Siri useful was a disappointment. By now, Siri should have been improved 10x over. Add in a Bi-LSTM module for chit-chat and you got a much better experience. It's such a waste of a perfectly decent voice recognition system.
That seems insane that it'd be the biggest check they've seen. I've bought an 80k BMW and an 80k Jaguar outright, and they both shrugged at me paying by check. BMW let me use a personal check, Jaguar wanted a bank check (easy enough).

Edit: A normal down payment for a luxury car of any brand can easily be 20k up front.
You are not alone.

After adding up the number of egerious errors made by the company, I'd almost be inclined to say the employee has grounds for wrongful termination or at least fraudulent representation to recoup moving expenses.
Thats not exactly true - you can be fired and laid off in a union, I've been both of those things while union.
People rarely talk about what went well in Vista.

There was an effort to componentize Windows. This was extremely hard to do, while the kernel itself had a very clean architecture, the layers on top - less so.

"Longhorn Basics" this was a list of fundamental stuff that every team had to either cover or explain why they didn't (Accesibility, I18N, security, etc.) this was a great way of making sure that these cross cutting concerns where handled consistently across an enormous team

Testing - it may be hard to see this from the outside, but the testing was off the hook. Hardcore static and dynamic analysis ran against everything

Never say never. I'm sure Marie Antoinette felt much the same and we all know how that ended, France was very much a first-world nation when it did.

What's interesting about revolutions is that it doesn't necessarily take much to trigger one, all it takes is a large enough initial event and you're off to the races. Just like chemical reactions require activation energy so do revolutions.

We already know that shooting black kids in the back doesn't seem to be enough, and there are plenty of other things that have been tried by now that apparently are not enough to trigger a major escalation.

But I really would not rule it out from ever happening again. Rather the opposite, it is a miracle that we've held out this long without one, which translates into a lot of latent pressure building up.
Depends on the content - HDR 4K content on both Netflix and Amazon is encoded in horribly low bitrate - about 12-15Mbit/s which makes it barely look any better than 1080p content (for comparison - 4K BluRay discs are about 60-100Mbit/s and look infinitely better).
I'm using uBlock on Safari and I'm not seeing this.

Still hopeful that we'll see something that universally disables HTML5 auto-play videos.
Starting to sound an awful lot like the U.S. health care system...
a woker at Upenn fell off a building and shattered the bones in his arm and hand. Upon arriving to Upenn hospital (a great one) they told him he would never have functional use of his hand again (bad for someone in this line of work).

somehow he knew senior orthopedics doctor that did most of his work with Pitchers for the Phillies, and he refused treatment until this doctor arrived. Somehow not receiving medication for the pain was all part of this, but he endured.

now he has nearly full use of his arm and hand, and the orthopedics doctor told him if he let the ER docs touch him, he never would have used that hand again.

Yes, it makes a difference.

Furthermore, and if you dont like it, advocate for more doctors and accountability for sub par care.
I think another way to look at this is minimizing risk/resulting guilt. The broken leg example seems to support that - the father is paying for the best possible care for his son, even if the outcome is the same (leg heals properly) as the ER doctor, the father has obsolved himself of the risk that he didn't do enough and allowed the leg not to heal properly.

In other words, the (I'm guessing) relatively slim chance there is a complication with the broken leg is not worth it to the wealthy father to take.
Buses are probably safer than cars, but many people still prefer cars, and willing to take the risks (and these risks are not insignificant). I have survived a near-fatal car crash (as a passenger), but I still drive a car, because in my Bayesian model of reality, convenience just outweighs the risk.

The same goes for private jets (which I can't yet afford), or private medicine.
Our sickness is that we have it good enough now. Most people live through sugar watered days of evolutionary affluensa stopping any chance of future revolutions.
At most we show our apathy in disapproval.

The only way we will improve from now on is through technology which rips apart old structures.
Well you should still be outputting full contrast. If it's not displaying black as fully black on your screen, there's a problem somewhere, probably in your playback software.

In MPC there's an option Render Settings > Output Range > 0-255 or 16-235. When set to 0-255 (default) my videos play with full black.
Not to be pedantic, but the fact that you are literally assigning percentage blames to entities means you do not, in fact, violently agree with me. Read the article I posted and you'll see why it is so important not to assign blame at all.
Millions of new vehicles are sold/leased each month.

What's your "lots" in that context?
Although the article doesn't specify the details of the program, but a typical visit to a hospital emergency room in the US is billed differently than a regular office visit with much higher mandatory co pays. By the example given in the article, it seems like their private "concierge" doctor shows up at the hospital, but what about the other costs associated with the visit? nursing costs, xray, ambulance, labs, other doctors? all of those are billed separately and patient's responsibility, and they are not cheap. If that 40k covers those additional costs at 100% as well, then it actually sounds like great value, but somehow i doubt it. But anyway, the folks on the $40k/yr plan probably are not concerned about the additional cost they just want fast private service.

MDVIP. Pay an annual fee in exchange for the doctor keeping a reduced patient load.

It's reasonably affordable without being velvet rope wealthy and gives you a much more streamlined care experience.
> Instead of leasing or buying a used car, consumers can finance a new car (e.g. 5 year loan). It requires slightly higher monthly payments to cover the principal, and you can't switch cars as frequently, but you have ownership of the car (and freedom from payments) after the loan ends.

Yes, and it's important to know that hire-purchase has existed in the UK for years as a method to buy cars, and this new product hasn't, and there's some confusion from the public about the type of product they're buying.
