Nielson and Chuang, while getting quite dated now [1], is still the best introduction to the conceptual framework of quantum computation and information. Its algorithms section though is not very detailed, and I found it difficult to teach my undergrad students from it.

The qiskit book gives a nice introduction to the algorithms, and contains all the latest algorithms, for someone wanting to learn the field.

[1] it doesn't include a lot of new advances in the past twenty years.

I only bring in Linux when I need it to get a job done!

I use MacOS and have an iPhone. I don't worry about the philosophy since they have for years done (mostly) what I need. If it look like MacOS will stop being useful to me, good resale values on Macs means I can move on.
China Per person GDP: $9,770.85 USD
US Per Person GDP: $62,794.59 USD

China isn't a developing nation? So they should just be happy with 1/6 of the wealth US Residents get and stop now?

What Crime is happening in their supply chain? Prison Labour is not illegal in the US or China. US constitution specifically allows it... How do we force Apple to take responsibility for this?
There is solid proof of Labour camps, Prison Camps, Reeducation Camps, and persecution of the Uighurs, even the Chinese "tyrannical dictatorship" don't dispute it. It is fairly common knowledge among Chinese citizens as well. What will probably surprise you, is it has much wider support from the Chinese people than you'd expect. Now this could be that the context of "why" they are persecuted is not well known outside of china. It could also be that Chinese citizens are not comfortable objecting to it from fear of speaking out against their government. But it's not as clear cut of "wrongdoing" that this article nor this discussion makes out.
People knew about lead in people’s pipes in Flint. They stopped buffering the water to save money, which leached lead out of pipes in people’s houses. It was a politically engineered disaster.
In France, there are distinct certifications: "Bio" for organic food, and "Label rouge" for high quality meat. For instance, animals with the later certification may eat non-organic food, but they spend most of their days outside, their feeding is sane, and the food process is controlled down to the distribution. No hormones, no chlore... Of course, some products can have both labels. And some farms, especially the smaller ones, apply similar processes but without any certification.
There's a neat program to handle that too: https://github.com/Herschel/Swivel
>Please indicate how the policies you support,

You can't stop straw manning me, can you? Please indicate where I showed support for 'tough policing'?

The only policy I argued for was this drone program because that has real potential in getting criminals out of the community.

The argument about 'tough policing' is not one of support, nor is it a justification of any police brutality. Police officers should be held responsible for breaking the law and 'police brutality' is against the law. All I argued is that the type of policing you get is a result of the environment. I made this argument as a counter argument to the trope that somehow policing causes crime and if we can just fix policing that crime will magically go away. That's not how it works. You can put as many regulations as you want (and police are already highly regulated - for good reason), but you're not going to get easy-going Nordic-style policing in one of the most violent cities in the world. You're also not going to lower crime rates either. Again: that's neither support for, nor a justification of police brutality.
Oh wow. Okay. Yes, ditch the animations. I genuinely cannot stand to use the site :(
I'm a research actuary working in reinsurance. Here is why I think Python creates more problems than it solves from the standpoint of most insurance business users:

1.) Environment management. There are many solutions for managing python dependencies, my favorite is Docker + pip. Good luck getting actuaries and underwriters to write Dockerfiles etc, and good luck getting I.T. to support Docker on Windows desktops. Like it or not, the best "feature" of Excel is that it is mostly the same on every corporate Windows machine.

2.) Unless you are using numpy / numba, Python isn't that much faster than VBA (if at all). Both are "compiled" to interpreter bytecode.

3.) Speed of development and traceability. Excel takes a lot of getting used to, but if you know the purpose of the spreadsheet (e.g. a reserve calculation), it's relatively easy to figure out what a mangled and convoluted formula is doing (Excel has a "debugger" that allows you to evaluate formulas by highlighting pieces).

4.) LAST BUT NOT LEAST. Many financial and actuarial (insurance) calculations are inherently recursive. Excel has built-in memoization (in the dynamic programming sense). It also has a reactive programming model. Good luck implementing that in Python without tripping up on the huge amount of function call overhead, even if you use a memoization decorator.
> Architecture review, product strategy, ensuring knowledge transfer and robustness to turnover, developing hiring plans, and ensuring your people are set up for success and are set up for career growth

Of this list, I would say only product strategy is leading. The rest is managing. Of course one role could and often does have elements of both. But leading means making decisions, rejecting some things and advocating for other things. Leaders have their butts on the line for their decisions. Managers are more the implementors of what the leaders decide.
These are simply tradeoffs. For example, one can make very fast protobuf parsers/serializers if you prioritize that over the ergonomics of the generated code.
Yes sorry, I typed it out from memory. I didn't think the exact wording would be relevant, when that was not the point I was trying to make. I have corrected it to the actual quote.
Not a bad idea. Congrats!

I was thinking of building something like this but rather for people I follow on GitHub: their contributions, comments, PRs and so on. A kind of a way to learn from one’s GH peers.
This feels like the kind of tricks Amazon should actively be defending against, with red teams trying to come up with angles of attacks, people looking for forums discussing possible approaches to game the system, etc.
Turritopsis Dohrnii, a.k.a. the Immortal Jellyfish
I've used excel and python in lots of business contexts. For most tasks involving domain experts, excel usually wins hands down.

An excel spreadsheet is usually easily auditable. The visual presentation and layout lends itself to review by others. You can click and point at values. Python and other programming languages require an environment and tooling that can't be easily supported across the enterprise. It requires source control systems and code review.

Programming languages are also too "dynamic". Using excel I can bring in a hard-coded report and link to those values in another tab. In python I'll have to save those to another file or re-query the data source, which may have changed due to new values being retrospectively added.

Python is the right tool for lots of analysis tasks, but for most corporate reports it's hard to beat excel. Programmers are also more expensive than corporate analysts. So you would end up replacing teams of low-cost high-retention analysts with high-cost low-retention programmers.
Each publication has always had a lowest common denominator target. The headlines are an indication of the audience. In latter days, all journalists expect their audience to be stupid.
You don't have to host it yourself ;)

Beyond that, there are a couple of things that I don't believe bors has.

A big one that I built for myself was the idea of supporting "working hours", i.e. only merge code during this timeframe.

For example, one company I worked for had some pretty flaky tests. Unfortunately, what would happen is we would have several PRs get reviewed and then use a tool like bors to enqueue them. Inevitably, some queued PR would have a failed check for this flaky test.

Fast forward to the weekend and a completely different developer would merge a hotfix into master. Unfortunately, a side effect would be that a tool like bors would try to merge the head commit into the PR with the flaky test, and now it passes! So it gets deployed at a random unexpected time, which isn't what we wanted.
Correct, the captain is not a managerial or decision-making leader at levels higher than pure implementation.

The soccer captain might influence who takes the penalty shot, but they don’t choose the lineups, tactics, player recruitment, training workflows, etc.

The “lead” in “team lead” is not referring to leadership in the same sense of this discussion, only in a much narrower implementation-only sense.

>Then the car was going too fast. Full stop. The rest of your scenario is irrelevant.

How can you possibly say that with a straight face?

There will be situations where a car is going a perfectly fine speed for the situation and then the situation changes in a way the car cannot have seen, known about, or anticipated resulting in a crash. This happens all the time with human drivers. It will happen with AI drivers too.

Furthermore, we don't subject anything else that moves to this burden, why would we do so for cars (AI or otherwise)?
Wherever practical, I back into car parking spaces. That avoids many many scenarios, while marginally adding a few new issues.
>but how controversial is the idea of true singularities being inside

I don't know any physicist that would believe this. Singularities happen mathematically due to GR being continuous space and time and material, but we know material is not continuous, and it's possible space and time are not also. So pretty much every one I have ever read or talked to about this believes that once GR is corrected for the quantum level, the singularities will go away, since they by definition would require quantum scale behavior, and it's known GR is not a quantized theory.

Note that the "Plank star" is a LQG theory, and LQG has so far failed to reproduce much of anything, so it's not clear at all how that will play out. It hasn't even been shown to reproduce GR at the appropriate scales, and it was recently a big deal when LQG was made consistent on a circle. It's no where ready to deal with 4D spacetime yet.

My guess is LQG, like so many other theories of gravity, will die out as more and more pieces of it end up disagreeing with experiments.
Different people have different priorities. Some might prefer [risking] death to physically visiting their prodigy less often.

Am I correct in assuming this grandparent lives on a different continent than the grandkids?
Same here. The most common term I've heard is badhiya or mast or even jhakas. Never heard anyone say ek number.

The closest I can think is ek-dam but a person would rarely say that in response to a joke.
That could work! I'm curious what makes subscription models more attractive from your point of view. Is it just simpler to understand? It seems strictly less flexible than a pay-for-what you need model. I suppose in your example the advantage is that you can get a discount by paying for more up front which is a clear advantage for people who will take multiple trips in a year or are planning a trip far in advance.
in college I interned at a consumer electronics company. there was an urban legend of this brilliance-worth-commanding-ones-own-schedule engineer who lived a couple hours away by the beach and only worked 2(!) 24 hour "shifts" per week. the rumored schedule was:

- arrive Monday 4am, work 24h
- rest for 24h tuesday, stay at nearby hotel
- work 2nd 24h shift wednesday, crash at hotel for a couple hours Thursday morning
- drive home Thursday, recouperate
- friday, saturday, sunday off

assuming one wasn't anchored to the usual 9-5ish type schedule of other life things (childcare, personal relationships, etc) and having the ability to physically pour ones self out to this extent, this has always stuck in my mind as the ultimate "deep work" type of schedule. enough time to focus on work challenges, time away from work to recharge, time for beyond cursory pursuit of personal interests, time to do personal admin type things requiring weekday time, etc.

The coach is the leader of the team overall. The captain is the player on the field who leads the team on the field. The captain is not the one deciding the strategy for offense and defense; he/she is more responsible for exemplifying character, work ethic, motivating others and keeping up team morale.
The article asserts:

"Based on the underlying genetic structure, we have already established that, if COVID-19 was the result of a lab escape, it was from gain-of-function research. "

This claim is illogical and does not stand. For example, a lab could have stored naturally occurring viruses that were then later leaked.

If the article is asserting that the virus could only have resulted from gain-of-function research, then why bother assigning a probability to it being naturally occurring.
Why is it important to look at the age?

You are implying that human life degrades in value as people age.

To take your view to it's logical conclusion:

We should harvest living old peoples organs to save babies.
Chat-based interaction certainly sounds like it could work for tech-focused events - I think for CCC one of the challenges is the sheer number of parallel talks, and keeping track of them.

Pre-recorded talks definitely seems like the way to go and having participation in the chat for Q&A seems like it would work well for an engaged and "fast typing" audience.

Thanks for your all your insights here - very useful to see what does and doesn't work for events. I think the move towards "hybrid" online and in-person events will be when it gets interesting.
Same but for Australian card holders. Interestingly or maybe deliberately the captcha doesn't show so you can't submit.

> Given that there have been exactly zero experiments conducted in laboratories close to black holes, isn't that qualifier kind of a cop-out?

No, I don't think it is. I agree of course that it's hard to test predictions regarding black holes. But I was addressing OP's statement that

> For example, you can use string theory to study the structure and behavior of black holes and holography, something called AdS/CFT, an area that has been incredibly successful.

and I merely intended to express my disagreement with the claim that AdS/CFT has been "incredibly successful". Successful in what way? Measured by what metric? Clearly not by the usual metric that says that experimental evidence is what counts. And on top of all of that AdS isn't even close to the spacetime describing the known universe.

> Given the observational knowledge of today, even a true theory of quantum gravity beamed back from the future would fail to produce verifiable experimental evidence in the realm of black holes.

I don't think this is necessarily true. See, for instance, https://backreaction.blogspot.com/2020/01/how-to-test-quantu...

> There are plenty of organic pesticides, herbicides, and fertilizers that are just as dangerous as synthetic varieties.

Don't let perfect be the enemy of good. The purpose of buying organic is signalling your preferences for eating healthier food. Yes, sometimes, the process we set up to do this, will yield worse results, but that just means we should try harder, not give up on eating healthier.

Humans typically aren't interested in killing themselves, but their judgement can also be pretty bad. 40% of traffic fatalities involve impaired driving. In 2018 Distracted driving was attributed to 2,800 fatalities.

Uber ATG's fatal pedestrian collision was the beginning of the end for the program. Uber CEO Travis Kalanick was pushed out of the company, the program has been shuttered, and one of the top engineers, Anthony Levandowski, is in jail (although Levandowski was not implicated in the accident, he's also not invulnerable).
Yes, I agree with that. If Protobuf hadn't been a reasonably-good design for Google-scale distributed systems, it wouldn't have won (within the company, or beyond). So regardless of how that design came about, we can say it is a reasonably good design overall. But only in aggregate -- not every individual decision can be assumed to be great on its own.
Distilleries that made hand sanitizer charged $14k surprise fee by FDA
So I looked into this a bit more.

I think the optimisations in the calculations threw me off a bit, but I understand now:

- to draw a curve, it has some starting angle and you move a small amount in that direction and then adjust the angle. The rate the angle changes is the signed curvature.

- therefore the angle change over the whole curve is the integral of the curvature between 0 and 1. (This simplifies the differential equations into dX/ds = (cos theta, sin theta), dtheta/ds = k.)

- because we don’t care about the initial angle, there’s a trick in the way an integral is computed to simplify the code (\int_{1-s}^1 f(s) ds = \int_0^1 f(s) ds - \int_0^{1-s} f(s) ds, but the first term is a constant so can be folded into the starting angle).

- the k0,k1,bias0,bias1 parameters give curves but they don’t much correspond to the things you care about (initial and final angle relative to the chord and chord length relative to arc length), so to go from the parameters you want to the curve, you do an optimisation step to find a curve for your desired parameters. This feels a bit expensive (you need to effectively solve the differential equation above to find the chord length. Maybe there’s an analytic solution (surely there is when f is polynomial) but there’s 8-18 cases and the integrals look gnarly)

- there’s an error in the definition of the basis function in the bias<1 case, it should be doubled.

I guess a thing I still don’t understand is what motivates the particular choice of the basis function. There doesn’t seem to be anything very natural about either of the cases. I was also thrown off by the definition of k because I expected it to be roughly like interpolation (I.e. f(b,-) would always be strictly increasing with f(b,0)=0,f(b,1)=1), but f(b,1) can range over a pretty wild set of values.)
Not just Dutch speaking but looks like it's specifically the city of Utrecht. Which is pretty specific, though the hostname tells you as much if you speak Dutch (it translates to 'Utrecht on the (your) wall').
I don't think you even have to register anything if you use a preapproved module so all of the iot stuff would not show up and only the module that implements 4g will.
The tricky part is as a society, we haven't trained many people for jobs where you build sociotechnical systems: processes and systems that have a major human element in it, and a major automated/computation element in it.

We have computer scientists who can make robust pure software systems with theoretical guarantees, and work well at scale. And we have political and administrative professionals who can converge on decisions and policies with actors with different motivations and rationality. But it's hard to do both really well at the same time, especially on the first try.

> Researchers from The New School and University of California, Berkeley, in a city-commissioned study, determined that drivers make about $9.73 per hour after expenses.

> However, Uber points to a study from Cornell University’s Industry Labor Relations School that found the median driver made about $23 an hour after expenses. That study uses a different definition of working time and makes different assumptions about driver expenses, among other differences.

> Under the new rules, drivers will earn a gross hourly pay of about $30.30 per hour, before expenses. The legislation will set new per-mile and per-minute rates for drivers while they’re carrying passengers, which are meant to be high enough to compensate for job-related expenses, time spent waiting for rides and time driving to pick up passengers.

The city found it to be just under $10, hence the 50% raise. Uber did their own math and found it to be $23. I haven't read either study but I don't trust Uber one bit with their calculation. Either way, they have to meet the standards of the law, not their own number they can define however they want.
The US response was shit but A) we have a timeline of events so we know it came from China B) the US didn’t cover things up, rather some politicians (trump for one) massively downplayed the virus.
Counterpoint - in nearly all cases (and I would say essentially all cases since Windows 8 was released), this was software that the user didn’t decide to install at all. Instead, it was installed for them by either their OEM or was included in Windows or by a browser maker or was part of some other software package (that almost certainly didn’t require it). So removing something that is a proven security risk, that the manufacturer actively deprecated years ago, and that it is shutting down server side in two weeks, seems to be far different than removing something that was a core part of the operating system. And even then, as others have pointed out, software updates remove features from software all the time.

I totally agree that it feels weird and is bad if an update actively uninstalls something for legal reasons, like Amazon taking stuff off of Kindles remotely, but we're talking about software the user didn’t ask to install and that the maker is shutting off anyway.

The vast majority of Flash usage was web-based and the web version will cease to be supported at the server level and at the browser level in a matter of weeks. Users that deliberately want to run insecure software or outdated web browsers have that option, and there are plenty of alternatives to display archival content.

Any non web-based Flash applications have been written using Adobe Air for over 12 years (and desktop Flash apps have always been a rarity anyway), and Adobe Air isn’t going away. If there really is a self-contained app (probably a game) that wasn’t packaged using Adobe Air that absolutely relies on an ActiveX plugin, there are alternatives the user can find and use. Technology becomes obsolete. And software stops running. At least there are preservation efforts out there.

There are infinitesimal edge cases where a user knowingly and specifically installed Flash Player for non web-based purposes. Those users are going to be given a warning before the application is removed, allowing them time to find an alternative way to access those files.
I would expect algorithms like that to put out likelihoods, not hard identifications. All it does is say "this person looks like that person". I wouldn't read that as "wrong".
