Why are you pretty sure it wasn't? Swift is usually pretty efficient. Massive numbers of CoWs is by far the most likely culprit for any kind of huge slowdown. And without actually profiling it, it's hard to detect when CoWs are happening, you mostly just have to be aware of when you're writing code that keeps multiple references to a CoW data structure that you're mutating. It's very common to get single accidental CoW copies. Getting a large number of them tends to require slightly odder code. For example, saying something like `col.reduce([], { $0 + $1.elements })`, which is a normal idiom for Haskell, will introduce a CoW copy on the accumulator array at every single step. And this is true even if you modify it to something like `col.reduce([], { var ary = $0; ary.append(contentsOf: $1.elements); return ary })`, because behind the scenes the reduce method will still have a reference to the accumulator while the closure is executing.

My random advice from the internet is collect more information from a neutral source: Payroll. Contact Payroll not HR and simply ask "How was my bonus calculated?"

1. Negative information: Don't react toward Payroll.

2. No information: Ask who to ask.

3. Mistake by Payroll, thank them for correcting it.

Then consider your options.

Good luck.

Perhaps I should have defined my use of the term. "Fiction" for me was implicitly referring to a narrative which tends to revolve around self or collective identities.

I think there is a distinction that can be made, which happens to be echoed by an intuitive sense that we have. We all dislike self centered people. Why is that? What is it about it that makes us uncomfortable? And why do we not like lies? Why do we resent when people posture? Why do we feel uneasy when someone makes a fake smile? Or when someone tries to convince us and you can feel their motive is self centered?

We all have in us a drive towards authenticity, genuineness, truth, whatever you want to call it.

What's dark or cynical about that?

On the science side, there is recent research looking into the "default mode network" that highlights how it appears to be the source of our self-related ruminating thoughts. In fact it appears that 90% of our thoughts in any given day are about "me", or some made up collectives which we use to extend our identity.

This amazing civilization we have built is not built with the self-referential type of fiction. It was built with our abstract thinking, and language capacities. (which is a practical type of thinking or narrative)

True, humanity is not going to drop their stories in a day. But I wouldn't lump fiction and abstract thinking together as "fiction". One is obvious fiction, which is based on identities, which in turn is based on our sense of survival; The other is of a more practical nature.
Peloton: The Self-Driving Database Management System
Android's lack of Google services in China isn't because Google "exited" (and by "exit", means moved servers to Hong Kong), it's because the great firewall blocks them. If you take a phone purchased in Europe or the US into China, Google Play Services won't work without a VPN.

Do you think the Great Firewall is an example of "how much better the market works"? You know, where BAT (Baidu/Alibaba/Tencent) are the oligarchy who controls everything? Have you tried Baidu's search? It's terrible, even for searching for information on the Chinese mainland web.

Your "see how much better things work?" is that 600 million phones are shipping with worse versions of Android, with worse security, lots of malware/spyware, and government censorship.

I suppose thats a victory for the investors with Baidu stock, and Beijing's thirst to control the flow of information, but it doesn't look like a victory for consumers to me, or an example of "markets working"

>you can take a day off to visit some particular community center that has outreach programs without worrying about state attendance records.

Honestly, I would love for this to be a thing. But I feel that it is far, far too optimistic. Most people tend to shy away from others that don't fit within their socioeconomic circle if given a choice.

"Kids would you rather stick around the neighborhood today, go to the zoo, or go into the city to a youth outreach program and meet some new friends!"

Crap. I forgot that Azanor wasn't OS. I can never keep track. And you're right about COFH (although they were always notably ambivalent about people looking at their code).

But yes, that was my point. Even BC and IC2 (which, while not as prominent as they were, are still giants, with BC still being the bedrock of the modding community) are OS, IIRC (although as demonstrated by the above example, my memory isn't the best).

I mostly see mods from a user's perspective, though, because I can't actually stand Java.

>> one does not apply a voltage to a capacitor, one applies a current

> This is meaning less.

A constant-current power supply is the preferred way to charge a capacitor wihtout destroying it.

> You have to apply an EMF (https://en.wikipedia.org/wiki/Electromotive_force) to get the current flowing in the first place. There is no current without EMF (measured in volts).

In a circuit without resistance, current can flow with no potential difference, so the above claim is false. As to circuits other than ideal ones, I draw your attention to the behavior of superconductors, in which currents flow endlessly until interrupted.

> The voltage across the capacitor rises (asymptotically) until it matches the potential of the power source.

For a constant-current source, the rise is linear. For a constant-voltage source, the current at time zero is infinite, barring stray resistances.

> You will reach 50v earlier if you use a 200v power source instead of a 50v source.

False! The issue is current, not voltage. The voltage on a capacitor is the time integral of past applied currents.

Capacitors have an upper limit to inrush current, and to charge one, you stay below that limit. The ideal charging source for a capacitor is a constant-current source, and the voltage driving the source is irrelevant until the capacitor's voltage limit is reached.

Consider a capacitor that can tolerate 10 amperes of current and has a voltage limit of 50 volts. Let's say I want to charge it as quickly as possible. I will apply 10 amperes of constant current, and cut off the charge as the capacitor's voltage limit is approached. Will I be able to charge the capacitor faster from a source of 200 volts than from a source of 50 volts? Of course not.

> Also the current at any given time is: I = VEmf/Rbatt * (e^(-t/(Rbatt * C)))

I am mystified as to why you posted a battery equation, and/or reference to resistance, in this capacitor discussion, in particular when constant current sources are the current state of the art. Surely you realize one doesn't attach capacitors to voltage sources, or is this still not understood?

Absolutely. I went to a private school up through 5th grade, then public elementary school for 6th grade, then junior high at a school that wasn't the one that my elementary school sent people to (the one I went to had fewer knife fights). Coming into a school where I knew nobody two years in a row was rather rough...

Thanks for your reply Dominic. As an end user, what should compel me to use Inferno for any production purposes? Bearing in mind React has the support of multiple billion dollar companies, several targets (web, native mobile/desktop, console) and a community of what is sure to be tens if not hundreds of thousands of developers. I just don't see the benefit of incremental improvements when they're not being integrated into that community. You lose all the benefit. I have no doubt Inferno is faster, but I suspect you're being disingenuous when you say all the same features are available.

The trouble I have is not specific to Inferno, but rather the idea that less and new is better. Eventually, your users will want something that Inferno doesn't offer, and eventually it will be implemented. And this will happen more than once, probably to the point where your library, too, is 45kb. So is all this work and fragmentation and confusion and comparing of benchmarks really worth it? I think not, unless the technology stands to bring something vastly different to the table.

The trouble with competing with React in its own space right now, stems from the vast amount of resources many of companies are putting behind it. You just can't make a Inferno Native, etc. I think we'd be much better off all working together on new ideas, not rehashing innovation in order to win benchmark tests.

All that said, I applaud the effort, as I'm sure this took a lot.
Exactly. Cuban and Shark Tank will still be able to back out of this deal and stay squeaky clean, assuming Howard Marks' story holds up.

The parties who will get screwed are The Style Club (more specifically the CEO), and Marks, who should have kept quiet and let her make the company a huge success with Cuban's help before coming forward with the dirt. He had the nut hole card but he flashed it too early.
I get where you are coming from, but things are often less Machiavellian than they seem, even if they feel that way. The Chalice team seems to have their own ideas about how to approach the project, some may overlap with yours and some may differ, from the conversation in the issue you mentioned (https://github.com/awslabs/chalice/issues/27) it seems like they were open to discussing ideas, but they wanted the freedom and control to experiment in their own project.

As with most ideas there is room for different projects and approaches and the landscape is constantly changing so it will be hard to tell which will survive. Even API Gateway's recent addition of the proxy integration feature makes things a lot simpler and probably made some code from all these frameworks less relevant.

So yes the internal AWS "team" has advantages in terms of being able to post to their blog and perhaps being privy to internal developments before you are, but that is just the way it is. Looking at GitHub the team appears to really just be one person https://github.com/awslabs/chalice/graphs/contributors. I just think we should have an open mind and allow for the possibility that they are trying to explore their own ideas and address what they perceive as their customers' needs rather than assume they are trying to crush all similar projects in the name of corporate greed.

None of those need street parking – in fact, you'd dramatically improve their experience if the parking lanes were replaced with dedicated transit / bike lanes, etc. and a few dedicated taxi/etc. loading spaces.

One of the reasons for this is that street parking is usually subsidized well below the market rates and so drivers will spend a significant amount of time looking for a cheaper parking space rather than simply parking in a garage, and they're using road capacity until they either find a space (and then block the lane while they slowly attempt to parallel park) or give up and pay to park off-street:

“In 2006, surveyors interviewed drivers stopped at a traffic signal in the SoHo district of Manhattan, and 28 percent reported they were cruising for curb parking. A similar study in Brooklyn found that 45 percent of drivers were cruising. The same results might be found on many other streets in New York because off-street parking is generally far more expensive than on-street parking. In midtown Manhattan, for example, the price for the first hour of off-street parking is often about $20, while curb parking is only $1. Parking for an hour at the curb saves $19, but drivers first have to cruise to find a space on the street.”

I guess I just never knew about the "company" part. I should probably review the history of the project, how it started, whether it started "corporate" with an open-source community (nothing wrong with that), or if it was originally a community effort started by somebody(s) then morphed into a company too...? I'm not expecting an answer from you or anyone - it's my responsibility to do the research of course.
Well, in that case the companies just have to not be the slowest gazelle, right? That doesn't seem like much effort involved, so the problem is probably in knowing what the other companies are doing so you're not the mark.

Aikido in particular seems to be very subtle

Which aids in the analogy.

If you restrict yourself to aikido techniques and your attacker has no such reservations, you have to be extremely good.

Good for the analogy.

I think it would be a mistake to give up on self-defense in general because of that. In any case, you have to go into it knowing it's not a guarantee, it just increases your odds.

Good points for the analogy.
It's the only permanent one that has remains we can find. But if they built somewhat-permanent structures using only wood and other perishable materials, wouldn't there be no trace of those?
Yeah, I studied Aikido briefly in college and found it quite powerful when a petite 65yr old Japanese lady could inflict the most excruciating drop-to-your-knees pain I've ever felt with barely a touch. But it takes a decade or more of diligent practice to achieve that kind of skill, and I found Judo, BJJ, and Krav Maga quicker to become effective with.
The show is TV first and VC second. As long as the company is entertaining I'm sure they don't really care. After the show I'm sure they do their due diligence. I would be very surprised if they went ahead and invested in this company.
I noticed the author didn't really expand on that either, but I really don't think Mr. Cuban would be happy finding out someone he has invested in has previous history of defrauding investors. Not to mention how little investigation was required to find that out.

You're right this doesn't really affect the tv show, people who work for the show, and the cable network. Absolutely nobody cares if the companies are "fake."

Your compiler could track those ints used as pointers all the way throughout the whole program and prevent out of bound values either at compile time or at runtime for compatibility. There is nothing fundamental about C that makes it incompatible with memory safety.

One of the things people worry about with schools is classroom size. That teacher may be very experienced; he/she may also be handling 25 kids. At our homeschool, the maximum classroom size is four. You can be less experienced as a teacher, and still be more effective.

They would be useful to terrorists. But they are more useful to people with peaceful purposes, by several orders of magnitude.

Any use that a terrorist could find for them can also be found by a security auditor role-playing as an attacker. If a terrorist could find a weak point in the infrastructure that may be exploited, so too may a defender, who may then devise a countermeasure, rather than an attack plan.

Those countermeasures would not necessarily appear on the maps. For instance, there may be a motion-sensing surveillance camera watching a locked gate on an access road to a reservoir for a municipal water supply. Such measures are sufficient to foil impulsive attacks, and planned attacks very often generate suspicious activity reports and probable cause for investigations well in advance of the planned event.

In theory, the maps may be a security risk. In practice, they cannot substitute for in-person investigation of specific sites, and most important infrastructure elements are at least partially protected against impulse crimes and accidental damage by chain-link fences, concrete barriers, motion sensors, and cameras. The typical terrorist candidate doesn't have satellite-guided ICBMs--they have to actually go to something in order to attack it. And they are constrained by the need for their attacks to be significant, public, and obvious.
Look at DES or MD5. Were they not designed by cryptographers?

Or how about the whole Dual_EC_RBG backdoor fiasco? Yes, there was criticism right from the start, but it was adopted and used widely as far as I know. Heck, Dual_EC_RBG was only ousted in 2013:

"The ANSI X9F1 Tool Standards and Guidelines Group which discussed the backdoor also included three employees from the prominent security company RSA Security.[6] In 2004, RSA Security made an implementation of Dual_EC_DRBG which contained the NSA backdoor the default CSPRNG in their RSA BSAFE as a result of a secret $10 million deal with NSA. In 2013, after the New York Times reported that Dual_EC_DRBG contained a backdoor by the NSA, RSA Security said they had not been aware of any backdoor when they made the deal with NSA, and told their customers to switch CSPRNG."

Besides, I think it's a good learning exercise to try to implement cryptographic primitives based on existing implementations. My opinion is that such language would dissuade people from even trying to design one for fun.

Disclaimer: do not design your own crypto primitive for production use.
I took the salt lake effect to mean that the students left in the public school no longer have a potentially intelligent (emotionally and/or socially) peer with which to interact. As has been stated ad nauseam, kids learn a ton from their peers, especially the ones they view as strong/confident/talented.

When "smart" parents remove their kids from the public school, the public school is worse off from having lost the student and parent would could have helped provide a better environment.
Great link, although Lenny has now wasted my time too.
Was thinking along the "invested in dishonest person" lines as well. At the end he makes a comment about thinking she was "honest", which wasn't "proven true."

Maybe a VC should have a better pulse on the companies they're investing in? Maybe as an investor, he should go to them and ask what happened first?

Seems rather unprofessional to air dirty laundry in a one-sided way. It appears this guy is just a crappy investor, IMO.

The title should maybe read "I possibly got screwed by not keeping a better eye on my investments."
> They're charged with power, which is current x voltage.

No, they are charged by currents. The normal power source for capacitor charging is a constant current source, one in which the voltage follows the desired current. The least desirable source is a constant-voltage supply, which (in the ideal case) will deliver infinite current at time zero.

The voltage on a capacitor is the time integral of past applied currents. The ideal charging scheme is a constant current source, which cuts off as the capacitor's voltage limit is reached.
