i have no idea what he's trying to come up with. there's no need to belabour the point plenty here have tried to show that the power of information (of all kinds: central bank actions, Donald Trump's tweets, corporate filing, obituaries, declaration of war, natural disasters, etc) and the ability to push order submission to the last moment is going to be king. the only way i can imagine one would nullify the value of information is to assign every participant of the market a random price on their trade that has no correlation to the value of the asset that they are trying to buy or sell.

> It is simply no longer possible to believe much of the clinical research that is published

Absolutely agree. I've tried arguing this with colleagues—that we should be more careful about the clinical conclusions we draw from single studies—but I'm just met with resistance. We just added a new drug to the standard treatment of heart failure, based on a shady Novartis-funded study that decided, in a post-hoc analysis, to exclude something like 50% of the patients after-the-fact (and oh look! now we can show a mortality benefit!). It spits in the face of everything I've learned about the scientific method and clinical research. This is the PARADIGM-HF study and the drug is ENTRESTO in case anyone wants to look into it more. Caveat: it might be a beneficial drug for many patients.

> It is simply no longer possible...to rely on the judgment of trusted physicians or authoritative medical guidelines

I'm going to disagree with the author on this one. It is possible to trust and rely on your physician, and in many cases you have no choice. Guidelines are just that: guidelines. Not a replacement for careful thought. And I actually like the direction that many guidelines are adopting: one that brings more continual minor updates rather than infrequent major changes. This is a complicated discussion, and depends on what illness you have that leads to your interaction with our health care system, but my advice is to seek out doctors that seem to communicate well with you.
Between PHP7, PSR4, and generally good development strategies, the only thing hack/hhvm offers in the near future is being tied to the hip with a single large company that both consumes and produces it.

Hack/hhvm were great visions of the future and definitely motivated the PHP7 WG to move at a more brisk pace, but tying yourself to something like that is not a great idea, imo.
Do you have the same complaint about, as another user mentioned, not being able to recover your data when you forget the password to an encrypted drive?

This is a pretty disingenuous analogy. GP did not ask about recovering data from the device. GP asked about starting over from scratch. Most people do have the expectation that an old encrypted drive can be reformatted and repurposed without knowing the key.

> There are a few compounds (like fentanyl or LSD) where the dosages are so small and the compound so potent that 10-25% makes a difference but for the majority, precision isn't that critical.

Wrong. Therapeutic ratio, not dosage.
Hmmm... I'm curious about the async explanation. I don't think that's the main benefit. The main benefit, at least on other platforms, is that while your function is await'n for your db, the thread can service other requests. It doesn't have to be stuck on waiting for I/O. This can dramatically improve scalability. I don't know, maybe PHP/hack doesn't really support this somehow.
These are arguments against the implementation, not the actual utility of the framework. One can have ugly internal implementation (which sometimes is unavoidable because you're solving hard problems), but clean interfaces. Regardless, Doug Lea anticipated these complaints in the comments to his code:

* Style notes
* ===========
*
* Memory ordering relies mainly on VarHandles. This can be
* awkward and ugly, but also reflects the need to control
* outcomes across the unusual cases that arise in very racy code
* with very few invariants. All fields are read into locals
* before use, and null-checked if they are references. This is
* usually done in a "C"-like style of listing declarations at the
* heads of methods or blocks, and using inline assignments on
* first encounter. Nearly all explicit checks lead to
* bypass/return, not exception throws, because they may
* legitimately arise due to cancellation/revocation during
* shutdown.
*
* There is a lot of representation-level coupling among classes
* ForkJoinPool, ForkJoinWorkerThread, and ForkJoinTask. The
* fields of WorkQueue maintain data structures managed by
* ForkJoinPool, so are directly accessed. There is little point
* trying to reduce this, since any associated future changes in
* representations will need to be accompanied by algorithmic
* changes anyway. Several methods intrinsically sprawl because
* they must accumulate sets of consistent reads of fields held in
* local variables. There are also other coding oddities
* (including several unnecessary-looking hoisted null checks)
* that help some methods perform reasonably even when interpreted
* (not compiled).

I find the "Calamity" article disingenuous. If you read more of the comments, Lea clearly explains the source of many of his data structures and gives an overview of how it all works.
Do you use it for thinking, or for more polished work? When I write, I'm just brainstorming usually, and it's pretty messy.(e.g. "What do I want to do today? Hmm. I'm not sure. What are the three issues on my mind? ...")
Maze in the Dark
Maybe I wasn't clear enough and should have qualified. What I meant was similar operations like the ones this thread is about:

- Putting stuff into trash

- Emptying trash

- Deleting large number of files with command line

From my experience MacOS is much faster for any of these. Add copying files to external hard disk or SD card to that list.

My statement was not meant to be about the overall performance of MacOS vs Windows.
Pseudo gradients are a thing. You can pretend its a continuous function and get gradients that push it in the right direction.
"Don't write PHP, write Hack instead" is probably a better title for this post.

The author could have chosen to write about PHP best practices that are ignored in the ecosystem at large, but instead chose to evangelize HHVM features.

For anyone who currently writes PHP like it's 2009 and wants to learn a better way (without dropping PHP entirely):

If anyone prefers to drop PHP entirely, that's fine too, but that's not the only good answer and pretending that all PHP is bad (like many of the comments on this thread already do) is very disingenuous.
> Would you propose that they just... stop scaling? Stop making new products?

Yes.

I want an economy where we have millions of tiny companies, each doing one thing, and doing that well. Like the German Mittelstand.
as far as I can tell, HFT shops aren't producing anything tangible. Considering almost nothing is as zero-sum as a stock market at sub-second timescales, their revenue is exactly equal to the costs for other market participants. For Virtu Finance, mentioned by another comment, that's around $800 million/year.

That's not really that much in the scheme of things, but it's only one company, and I doubt the other investors would be willing to spend similar on insurance against volatility.
I'm disappointed that the King's Assembly and Keymouse both turned out to be vaporware.
I've always thought that the best way to launch is a Show HN and a reddit post on some related subreddits. Is this a better option for the launch of a productivity app?

Surely a productivity app launch can't be that interesting for news.
You don't negotiate in a vacuum. If you participate in writing that algorithm that exerts downward pressure on salaries generally (because it's more efficient/effective, and it's applied at the level of a tech behemoth with a lot of influence), you're incrementally lowering the baseline from which you and everyone else negotiate. You're basically arming the other side of the negotiating table--and that other side is already a multi-billion dollar unicorn.

At some point, you'd think a basic sense of self-interest would remain. I swear, if someone held a contest to design a better rope for hanging engineers, we'd fall all over ourselves trying to win. If someone kickstarted that idea, they'd need new stretch goals in an hour.
Yup. If it's an experienced technician, then memory is a factor for both tests.
I was working for a tech support/student financial aid support center for a couple months and was fired for finding and using an exploit.

It was getting close to Thanksgiving and all the employees had to do state mandated online ethics training (this was a Connecticut state job).

The online ethics training was honestly bullshit, it was poorly designed and even more poorly implemented. Some slides wouldn't load fully and others would be buggy. I had to restart it about 3 times.

In my frustration I looked into the source code for shortcuts and found a javascript file which included a function called SetScore(min,max,val).

After opening Chrome dev console and trying the function, I exited the training and refreshed to see a score of 100!

I immediately emailed my managers, and the admin of the site where the training was being hosted. 2 weeks later I got a call that I was terminated.
Since I'm sure this will quickly be a debate about PHP, these are the reasons I liked PHP at the time:

1. Ubiquity across web hosts.
2. Native support for JSON-esque associative arrays.
3. Integration with HTTP seemed amazing compared to other languages used for CGI.

1's not an issue anymore thanks to the cloud and other improvements in hosting services. 3's not an issue either thanks for good web frameworks in better languages. But 2?

Flex / JavaScript / PHP really are a pleasure to write some things in because of the flexibility of those data structures. Working with JSON, etc. in Java and friends is really painful and boiler-platey. Anyone aware of really good implementations that feel like PHP / JS in more widely respected languages?
Here's a better version of that link: http://www.phptherightway.com - using a different runtime is not going to make someone who doesn't know anything besides mysql_query or include write better PHP. You need to start with the basics instead. Your post is what I would call premature optimisation.
That is nowhere near what I am saying.

Async queries, great advice..do that. The rest meh...

The bad:

"Use HHVM". Do not do this, just upgrade to PHP 7. HHVM does have better performance [in some cases, not all], but it also has many unsupported modules [such as Memcache based sessions]. It's difficult to get improvements added and you're going to get frustrated by something people in the mainsteam PHP branch can do that you cannot do.

?int $var = null;

This is a question of style. Personally, i can read it, but it is a little odd and I've seen people get confused over it. I'd personally avoid it. The null check and type check is much clearer.

This question appears rhetorical (with an intended answer of "no"), but I absolutely think such a risk should be considered, whether or not you're a parent. The higher-order bits here are probably the time you're wasting with 100% probability, perhaps the increased life satisfaction of a great job, etc, but the p% additional chance you die in a car crash, as you said, is non-trivial, and even though I know very people incorporate such thinking into their decision making, I think they should.
As an amateur musician...I don't think so. Big heavy binders fall off music stands easily. They get stuck on page turns. The music stand itself is either very top-heavy (for the professional ones in concert halls) or it's flimsy and won't hold a heavy binder (for the folding travel music stands). These are all the last qualities you want when working on an extremely expensive, precise piece of equipment.

One of the most useful smartwatch apps I got was a metronome app, simply because it's hands-free. I wouldn't spring for consumer Glass (simply because it was an order of magnitude more expensive than a smartwatch), but it's even more useful for musicians. Imagine never needing to do a page-turn again!
OTOH, the last time I told someone I wanted $200/hour, he said "if you can fix the problem today, I'll write you a check on the spot!"
I think you're far too eager to look for and criticize anthropomorphism - hence you see it where it's not.

Korea and Taiwan got their best economic growth stage when they are in an authoritarian stage. China is still in this stage.

Besides these countries, there are many countries, such as many in Africa, doesn't become better after the democratic process.

The Chinese government has a point that "Let's concentrate and grow the economic first. After everybody has a much better economic status, we can consider other things". I think they did have a good point on it.
>Canadians tend not to talk about making their country great again. Canada never was particularly great—at least not in the sense that Trump uses the word. Unlike Americans, Canadians haven’t been conditioned to see history in epic, revolutionary terms.

To be fair to Americans... once upon a time, they really were were that far ahead of everyone else. In 1945, it's estimated they constituted over 50% of the global GDP. You are the global economy at that point, and that's going to distort anyone's perception of what constitutes fiscal propriety. Most politicians were born either during this golden age, or a bit after when things were still very rosy. The US still represented 40% (edit: of gdp) even when relatively young politicians, like Barack Obama, came into the world. It's difficult to convince someone he can't just cut taxes to generate more good will with the electorate when, for most of his professional life, the economy was so good he could do just that and not seriously hurt anything.
You define centralized exchanges as banks (as they are usually).
A decentralized exchange has a different model. There is no credit and IOU conversion but a direct exchange of BTC to Fiat (or other altcoin). For escrowing the trade amount we use Bitcoins Multi-signature feature so the blockchain is the escrow.

Now, with a full vr headset, it might make sense to be able to place such things outside of the normal field of vision (where your text/code editing resides) - but so far I don' think working full time in VR with text is a great idea, with the current generation of headsets.

Trading is probably essential, it definitely is given our economic system which involves trading. In my opinion, HFT does easily merit singling out for evaluation. It is a relatively marginal economic activity, but accounts for a large portion of transactions, mostly in highly liquid markets purposely designed/evolved to be highly efficient like stock markets and other tradable securities markets. I don't think pure theory economics can say much about what happens at extremes like that. Transactions are prices and information. If most transactions are based on HFT strategies divorced from anything even remotely related to an understanding of the underlying asset, who knows what wheels fall off the theoretical model and/or reality. It's worth looking at, at least.

As I said though, I agree with you that there's an onus on those proposing a HFT tax to convict it convincingly. I don't think this has happened yet. The argument can't be "weird and scary." I don't see the liquidity defense. How can liquidity beyond a certain point be meaningfully more useful, but that's not a conviction. In my mind, it rests on how HFT impacts economic fragility, and increases the likelihood or impact of busts.

We're talking about something like a 0.02% of equity tax on HFT specifically or lower if it's going to be everyone. That does not impede the ability to price in real information.

An artificial restriction on trading is not unlike natural ones. Did we have liquidity issues when trading in and out multiple times within tenths of seconds was impossible? I don't think the cost is high. The risk is ..unproven.
> That the doctor or someone else will take the time to re-watch the recording of your interaction? How is that better than just extending the interaction?

You can outsource the data entry parts of the job to someone in a centralized location, who can be assisted by voice-recognition on an initial pass. This saves time for the doctor and patient, and lets the doctor focus on the patient rather than data entry.

Incidentally, you might not currently be recorded on video in the doctor's office, but there is already a very good chance your doctor is dictating notes describing your medical history using scribes in India or elsewhere.
>How is a minimum wage job not optional? People stay in their minimum wage jobs because it is better than their other options, not because the company forces them too.

Because by optional we mean a totally free choice -- not merely the necessity to chose among N available options (lest you starve).

There are degrees in freedom (a rich person doesn't have to work at all if they don't feel like it), but when you're scouting for minimum wage jobs, you're at the lowest of those degrees.

Funny. As a Canadian, I look to (and moved to) America to achieve. I find our government, at many levels, to be very slow moving, averse to change and frequently lags behind the US in allowing innovation. Vancouver's down-right refusal to consider ride-sharing apps is nothing short of corruption. The archaic alcohol laws, including prohibition of transport of booze across borders (except for made-in-Canada wine, gotta protect your favoured industries!) is another example.

Looking north across the border, it's easy to see a greener field, but Canada has suffered a decades of brain-drain and poor multi-factor productivity because of slow, restrictive government policy and a refusal to embrace innovation. It's a shame it takes this long to enact change.

Relax, this is the real world, not a computer based series of 0s and 1s. Any such compound begins drifting off from the original specs as soon as it leaves the factory - and in a very real sense it's not exactly at 100% at any time post the moment of manufacture. The question is what kind of deviation can be tolerated.
Specifically, it is imagined that even severe and abruptly implemented tax cuts will serve to actually increase government revenue, thanks to the turbo-charging effect on economy growth.
