I'm halfway through the first chapter of Neilsen and Chuang's book. I'm enjoying reading about the subject and am at the quantum parallelism part.

Can you explain why Grover's algorithm has a runtime of root N? It seems like the runtime should be log2(n) because of exponential qubits or 1 because there must be a way for all the qubits to interfere.

Also,
What resources do you reccomend for self study? Are there quantum computing meetups in San Francisco that you can recommend?
The parent's post was fine and relevant. Yours is self referential.
No. If you read the article they explain that they send segments of your trips, and never the start or end segment.

So even if they could find all the segments from YOUR trip (which they can’t, according to what they’ve said) they couldn’t even reconstruct what you were doing, only a few small stretches of road you were on.
>if only for the tighter integration with the OS itself and reportedly better battery life.

So, gmaps is more accurate and overall better in execution, but you recommend an inferior product because of OS integration and battery usage? Makes no sense to me. The number one priority is getting the best directions to where you want to go.
I'm very ready to move off of Google Maps, but as of yet, I can't emulate the biggest feature it has for me elsewhere: a spacial bookmarking system. My primary use of Google Maps is to remember places that I've been recommended by other people, and then when I go "I'm traveling to Portland, what places should I go?" I can check Google maps for everywhere I've tagged before.

If Apple Maps gives me that, especially if it syncs from a webapp to my phone, I'm in.
iOS 12 allows mapping apps to be used via CarPlay.
It seems to depend an awful lot on where you are in the world. I've rarely -- not never, but rarely -- had problems with Apple Maps, and I tend to prefer it to the Google Maps iOS application. But, I also live in the San Francisco Bay Area, which almost certainly makes a difference. To be fair, I've also had no problems with it in Portland, Seattle, Kansas City, Lawrence (Kansas), Eugene (Oregon), St. Louis, and around Tampa Bay. But it's not lost on me that all of those are not only in the United States, they're all pretty urban. (I've heard anecdotes of Apple screwing up in urban areas, too, but for me it hasn't behaved any worse than the other mapping apps -- Google has sent me to a few weird places.)

I think on the whole it's good for Apple to be taking control of their mapping back end, although I suspect it would have been better for them if they'd started by, say, buying Here (the former Nokia mapping unit).
~100k LOC in Crystal? that's pretty amazing

Suppose wash trading is indeed occurring, what is the benefit to the perpetrator? Fees are 0.20% for both maker and taker on Kraken. You'd have to pay ~$52,000 to print a $13 million trade.
Have some perspective man! in the bigger scheme of things, one user does not matter to Apple. Buy what works for you.
I don't understand the point you're making. Are you saying that we have it all backwards, and that the wrong people get promoted, while the smart prolem-solvers get stuck in low level position and ignored?

Because in that case I have sympathy for your plight, but would still like to ask:

Are you actually trying to make that argument by pointing out how counter-intuitive a story is you just made up?

As to the actual problem: It is both well known and not as easy as some low-level interns think: Fundamentally, Maps only does this when it finds absolutely nothing relevant at the user's location–these are almost always (really bad) typos.

In that case, the only alternative is to completely ignore the far-away match, frustrating users' #1 expectation of how a search engine works. Or to present the user with some dialog "oh but that's far away!"

The latter doesn't help anybody, because the user can return with the back button, just as easily as by declining the notification. Yet the user who actually intended the search gets inconvenienced.
280k is not a high number for a senior SAP consultant with a big mouth, but 4M indeed is but definitely not impossible or even rare. Anecdotal, but at least I already know 1 person from my own friend group, a friend worked as SAP consultant in utility; he started his own company specializing in SAP for utility but he wrote specific small tools for parts where SAP was(is?) very hard / cumbersome to use or where it has gaps for the particular (big) electricity providers he contracted for. Selling those on the side next to his high contracting fee, he made (makes) millions.
I can attest to this, the amount of times I've had a look and used go's stdlib as a reference for what to do when implementing something in the std for crystal is too many to count!

Unfortunately, transpiling has a huge bunch of problems, which you can see in for example how quickly nim vs crystal compiler matured - even though the crystal compiler is more complex. I'd be interested in seeing go's stdlib, ssa backend, and toolchain turned into a robust library. Like LLVM but including a GC, a stdlib with a CSP implementation, and a complete toolchain for static compilation.
No, it doesn't seem contradictory, and it sounds like Apple is doing this the right way. If identifiable information never actually leaves my device then where's it going to leak from?
When Slack was down, I was able to get a couple extra days worth of work done.
The article said they’re using computer vision for that stuff. Between how good CV has gotten, the other data sets they’re comparing to, and having human editors hopefully they’ll be able to do a pretty good job.
Note the author worked on Apple Maps for the first few years.
In my understanding, the relevant quantity determining attenuation is the integrated amount of material in the column between the source and the observer. So, the small density is compensated by the large volume of column (distance to source).

Choosing Elixir for the Code, Not the Performance (2017)
As a programmer and practitioner, I'm curious about what kinds of skills and training it takes to program quantum computers.

Can you shed some insight into what's really different about the tools and task of programming a quantum computer versus using classical programming languages and tools? Do you think quantum computer programming will rapidly become standard training for CS undergrads, or do you expect it to remain a niche skillset like FPGAs, etc, since it will only supplement and not replace classical computers.

Also, nice to meet you. Your essays have been inspiring over the years.
I'd love it if any of the map makers had a button for "I am on a bus", which then i) sent a ton of data to them to improve their maps and ii) provided a more useful map version.
Isnt there a "Search this area" as you move the map to a different location?
The entire point of using a map is the data. Who cares about the chrome of the app?
It sucks enough that I avoid clicking address hyperlinks on iPhone, and instead copy-and-paste them into gmaps
Thoughts on this comment?

"You don't actually want qubits, you want an analog computer with differentiable signals. Most likely photonic. Qubits are a dead evolution branch.

I've been recently exploring computational metamaterials for photonic computation.

http://users.ece.utexas.edu/~aalu/research%20-%20page%203.ht.... (there's quite a few papers on this but unfortunately they are all paywalled. Spoiler alert, they seem to be based entirely on Fourier transform).

These computational metamaterials don't need electricity to be powered (you need something that will shoot the photons on them and read back the values off tho).

Machine learning would be much, much faster on these as you have O(1) differential calculus.

They don't heat up. You can possibly build a house sized CPU out of these. I can see it, a city block sized CPU and a nuclear reactor next to it.

Did you know that on an analog machine, you can do sort in O(n)?

https://en.wikipedia.org/wiki/Spaghetti_sort

Hit me up if you wanna chat about this. I've seen the "light" (xdddd) now and can't go back to stupid bits.

I'm not like super married to the metamaterials but analog photonic trumps quantum for just about every task I can think of."

But this implies that the second bigger trade was independent of the orders on the books, giving an expectation of a proportional amount of movement. But this is very likely to be false. If I'm making a large purchase of an asset with a known value, I'm going to wait for enough volume so that I'm getting a fair deal. The analysis in the article doesn't mention how the order books evolved during the time period analyzed.
You don't get to decide what words are offensive for some people unless you are part of the subject group of said people. Anything would be a misunderstanding of the word "offensive".
Did you read the article? They’re not going to be using OSM or TomTom anymore, they’re taking it all in house preciselynso they can fix those kind of issues.
> If it ain't broke (any more), don't fix it

Something is showing Apple that it is broken. I am betting it is user rates. Google has taken over iPhones for so much of it and I am sure they don't like the fact that Google Maps are used more then Apple Maps.

On my imperical evidence side, my daughter uses Apple Maps and I can tell you it gives back mapping when we are less then an hour away but more then 20 minutes. For example the way i drive isn't on Apple Maps and it adds 5 minutes to the trip and Google Maps has the trip 5 minutes faster. I don't know if Google is getting that data from my driving or from better algorithms but it has happened for then a few times.

Typeform has leaked private customer data
[Just got an email]

My name is David Okuniev, and along with my co-founder and joint-CEO, Robert Muñoz, we’re writing to inform you that a data security incident has occurred within the Typeform platform.The incident compromised some of our customer data, and some data from your respondents.

On June 27, 2018, our engineering team discovered that an unknown third party gained access to our server and downloaded certain information, including some of the data your respondents provided via Typeform. We responded immediately and closed the source of entry. Our engineers are closely monitoring our platform, and we’ve found no evidence of any recurrence of the incident.

To date, our investigation has revealed that your account was compromised. Only some of the data provided by your respondents prior to May 3, 2018 was affected.

As a data collection company and service provider, maintaining the security and privacy of our customers’ data is our top priority. As part of our rapid response to this incident, our team took a variety of measures to ensure the ongoing security of your data. Because each customer’s typeforms are different, the data downloaded during this incident will vary by customer. You may want to communicate with your respondents to inform them of this incident. Please see the Q&A below for more info about this.

In addition to the steps taken to date, our team have launched a comprehensive review of our system security to identify ways we can further increase our security measures to prevent future incidents. After the review, our system will be more secure than ever before.

We take security matters seriously, and we sincerely regret that this incident occurred.

Oh crap, now we're going to be stuck on python 3.7 until python 4 comes out.
No, the dilithium is somehow supposed to help control the matter/antimatter reaction. The antimatter is stored onboard in magnetic bottles I think.

But yeah, it doesn't make that much sense.
Do you think the state of the art in quantum computing is already more advanced than we realize, in the same way that the state of the art in cryptography was when R, S, and A thought they had discovered RSA?
Really depends where you live. We live North of Boston and still countless times run into issues where the dot is the wrong place, or the location data for the place going is wrong, or Google maps provides extra relevant info like it will be closing before I get there, or when the store has special hours google maps knows and Apple maps doesn't, and countless other differences. I still use Apple maps mostly because the integration with Apple Watch and iOS (getting back to the app) and notably using Siri make it for a better experience and if going somewhere new ( a long drive) I check with Google Maps first to avoid any major issues. If Google Maps on iOS was allowed to be deeply integrated like Apple Maps wouldn't touch maps with a 10 foot poll, but that will never happen. So any improvements to Maps data will be a welcome improvement and while hard to imagine them beating Google Maps they only have to be good enough to beat them in the long run.

What choice do they have? Maps, location data, and the services they enable are critical to mobile devices today, and will only get more so with AR and devices without screens.

“Everybody but Google” isn’t good enough judging by the current state of affairs, and Google doesn’t play by the same privacy rules as Apple, so they seem to have few options.
We don’t know they’re not. There have been hints they might be.
> There is zero chance that all of these markets are manipulated

This lacks the imagination of market manipulators from even the 19th century. For more modern context, see penny stocks. These are traded OTC at a variety of venues. Manipulation is trivial given (a) prices on one venue are broadcast to others, thereby letting one bad apple spoil the bunch and (b) electronic trading makes overseeing dozens of accounts easy.
OP here.

Has anyone else received this? Want to understand how widespread this is since no public communication (yet) by Typeform.
While I think there is a 0% chance we will see a Macbook Pro redesign similar to the 2013-2015 15" rMBP that is so coveted by a lot of devs, I would certainly love it if Apple released a proper mobile workstation (which will not happen).

If Apple released a mobile workstation with the same (or similar) form factor as the 2015 15" rMBP with the same keyboard (and obviously get rid of the touch bar), same 99.5 Wh battery, same port selection (except replace TB2 ports with TB3), same Magsafe charging port, updated internals with non-proprietary, non-soldered RAM, SSD, and wireless card, I would pay whatever the hell they would want. It won't happen, but a man can dream.
How your projects in motion with animated GIFs
Sorry, I don't know what "emergence" means in this context. If you mean AGI, I think (hope?) that we're still quite some ways away from it. Yes, quantum computing could help with AI -- for example through Grover's algorithm, which lets you solve many search, optimization, and planning problems in roughly the square root of the number of steps you would need classically. But it's a complicated story: many of the problems we care about will still be asymptotically hard even for quantum computers; conversely, as the spectacular recent achievements of deep learning and reinforcement learning (not to mention our own brains? :-) ) remind us, there's a great deal that can be done even with classical computers---often, outside the regime where we understand theoretically why the methods work. If you check back in 5 years or so, I'm optimistic that we'll know more about the applications of quantum computing to AI than we do right now.
According to the book by Axel Sandemose which defines the "Law of Jante", it is a custom which the proletariat uses to keep each other down.
Yup. If the app was map-centric you wouldn't have to ask. Just start showing more markers.

If each query was a layer, you would also have a basic GIS. You could allow the user to start asking spatial questions, such as, "Show me where all the Chinese food restaurants (layer 1) Best Buys (layer 2) are.

"Hmm. I need to go to Best Buy but I'm flexible about food. Let's tap X on the Chinese food layer and search for Poutine restaurants instead."
> zoom around until the name of the street I'm currently in decides to appear.

This is especially bad if you're on a bus and want to see where the stops are, so you know when to ring the bell. GMaps makes you zoom so far in that you're constantly scrolling the map to keep up with the bus.
By anonymized, I would take it that they mean no user or device-specific details are linked to the data when it's persisted. So when it's leaked, it's not as though someone can say "this iPhone was at this place at this time".
Using Serverless Architecture Is Not All or Nothing
Yes, absolutely. It would make sense either for funding bodies to provide ways to fund contract developers or for even smaller institutes to be required to spend a portion of their budget on full-time developers (instead of spending it all on machines and student staff).

For the actual data science, as opposed to writing new software packages, it would be reasonable for students to maintain lab notebooks (except for computer experiments not wet lab ones), with exact versions of everything, exact steps, name, size and checksum of every dataset, and so on. I think things are definitely moving in that direction but this is a skill that is not beaten as much into grad students as recording wet lab work is. But in time it will be.

Though, my experience in wet labs is, both quality of the lab notebooks and quality of the labeling of the stuff in the fridge definitely varies.
Honestly this isn't suprising, given the huge advancement with Graal. Nashorn was really cool in its day, but compared to Graal it's slow, hard to work with, and error prone.

Still there's a certain respect that I feel when seeing projects that were great retire. In our memories persist the greatness.
one common comment is how the traffic data for google maps (and waze) trumps the quality of other map alternatives because it has the most users and therefore the most data for real-time traffic.

could anyone with map/traffic experience please comment on when data scale overshoots functional requirements? that is, what is the user threshold (e.g., 1,000 users in the same 5 mile radius) above which traffic accuracy stops improving?

> An image search for mIRC shows that it is ugly as shit.

ok

> It has a sidebar to list channels but the current channel window is still an undifferentiated mess of handles, commands, and actual conversation.

No.

Each channel and private message get their own MDI window you are free to minimize, maximize or layout however you want.

Notifications are turned on by default, but they can be disabled. You'll get a tray notification if mIRC is minimized, and inside the title bar of the window will flash. Notifications happen when your nick is mentioned.

There's a horizontal line that goes across the dialog window that indicates the location of the conversation the last time it was focused.

>Even if mIRC would suffice for Windows, you've not handled Macs, phones, etc. Who gives a shit if it runs on a 25 year old computer?

Other clients work on other platforms. mIRC is just what I brought up since it's desktop windows client and that the most common case for an office environment.

> The US military has produced some specific examples of good design but isn't known highly valuing usability, let alone whether someone would enjoy using a tool. IRC is very functional and mIRC appears to add a little polish beyond a pure command-line interface, those are bare minimums and not good enough.

It's a simple, light-weight way for people to send short text messages in near real time with tens of thousands of people. I think that's good enough, and it works at a scale that far surpasses the SaaS chat options.
Relative growth. It's not quite fair to say Idaho isn't growing on an absolute basis.

By that same measure, Singapore could grow by 20% and it would be "nothing" compared to 2% in the US.

iTunes was great up through the iPod. Adding the iTMS wasn’t bad.

Movies was not a good idea. Apps was too far. Music (the subscription service) was stupid. Then they forced UI changes on the old/working stuff because of the new garbage.

iTunes WAS great.
Honest question - How does the tighter integration with OS help when you're trying to do directions?
> I wonder how climbers overcome this?

(Personal experience, and I'm shit, so pinch of salt.)

The difference with what you describe is that you have a time pressure - you're being passively carried into the state where you're afraid and reactions etc come in real time.

Specifically when doing free solo stuff - I have time to "override" my responses if that makes sense? It takes conscious effort but I am moving at my own pace, I can rest, take a deep breath, etc.
"make even basic tasks sometimes extraordinarily difficult, or so I've heard"

That would be an understatement :-)

But it's a trade-off. You fight the borrow-checker to ensure safe code.

It's really subjective. Are you using a language for front-end/middle-tier service/back-end process, etc. etc.

Back in the day - you had a handful of people writing C code via CGI for web development.

Every good language addresses a problem.

Rust = safe code.
