I realize that I made an assumption in my first answer, that the moon is not rotating. A rotation may cause you to move out of the orbital path of the bullet before it gets back to you. If you shot from the poles though, you would remain in the bullet's orbit.

That said, in ideal conditions, even with rotation, the bullet will hit you eventually, but not for a long time on average, given the scale of the moon. In reality it's orbit would probably destabilise due to collisions with dust and perturbations from other gravitational bodies (the Earth, Sun, etc. create an n-body situation which slowly changes the orbit over time).

> Does there always exist a velocity `v(theta)` that will make the bullet hit you in the back after one orbit?

The velocity must be great enough to stay above the surface, and not high enough to escape. Additionally, you must shoot horizontally, like I mentioned before, and not rotate out of the orbit (e.g. by being at the poles, or at the rotational equator, shooting along the equator).
Similar in the UK - set up that way to stop money being able to buy elections.

Overall, election spending has been very strictly controlled.

One of the problems is recently people have being getting around this with hard to trace online campaigns - using "national funding" and effectively locally targeted online campaigns.

I'd like to see people being properly sanctioned for breaking the rules. In my view there are few things more serious than trying to subvert democracy. It shouldn't be normalized like it is in the US.
Just enough time to accuse someone of having ties to white supremacy but not enough to hear an answer.
From my own experience (finance), still no cloud services in use. It is strictly forbidden to share any data with the outside world, whether that be in the form of Google Sheets or some other platform outside of a corporate network. If something moves out, shit hits the fan pretty quickly, once someone finds out.

If you have competent or better domain modeling skills, the database route is optimal. In general, Object layer domain modeling (typical in industry) is mainly addressing skill gaps in domain modeling, relational dbs, and SQL.

Of course, if you are writing something like Microsoft Office, where there will be pervasive reuse of object layer components, an Object Domain Model will be a better fit - it makes sense to define the system fundamentally at the object/component level.

In my experience in the industry, the rise of object layer modeling was due to multiple issues, some noted above and also including organizational factors such as the traditional DBA/Dev divide, licensing, etc.

So a pure technical approach to this question is, imo, non-optimal. It is ultimatley a business decision.
What’s the current status of the JMAP spec? Are there any available clients or servers?
One company I worked with had been around before cloud. They had plenty of server space (about a few building levels of servers) and even a backup power generator. I suppose they would move to cloud if they could, but at that level of scale and uptime, they might as well be the cloud.

I would call the moving goalposts a subtle sign of a win as well if it is getting closer that previous "unthinkable" tasks need more qualifiers. Missing or adding them makes it easier or harder. To be a smartass anything can pass a text messages from the comatose (that is nothing) and nothing can reliably "prove" itself god by say resurrecting and teleporting your dead relatives to you would be obviously useful but impossible as that isn't something text messages can do.
That depends on how you treat people with great potential currently. I would tend to give them a lot of leeway and personal responsibility and trust they can get things done. I think that is what Frankl means.

Saying "You are amazing, here is an A for trying" is a different culture entirely, and came from somewhere else.
Is it...?
That depends on how large the misprediction penalty is and how many times the branch executes. Branch prediction isn't magic. It never makes branches beneficial. The best it can do, with perfect accuracy, is bring the amortized misprediction penalty down to zero. The key is that Duff's Device also relies on branching, and it's a less predictable branch that's more likely to be mispredicted. On the other hand, one BP miss is still cheaper than several hits plus one miss at the end. On the other other hand, there are issues to consider like code size and cache turnover (favors a loop), handling of special cases where larger loads/stores can be used (favors DD), processor extensions, etc. If you're really trying to write an optimal memcpy-like function, you'll probably end up using a hybrid of several approaches - including Duff's Device.

Yes. It's all a show. The "journalist" pretends that congressional hearings are serious events rather than the entertainment clown shows that they are. Then said "journalist" compares the performance at such a show-trial light to dialogue in a fictional movie. People click on it. Ads are shown. Comments fly. Money is made.

It's all good. But I happen to be very serious about the importance of an earned income as a social good. I think we need more of that.

We are indeed interested in targeting AMD GPUs. There is a prototype backend available at https://github.com/JuliaGPU/AMDGPUnative.jl and we are closely following the status of SPIR-V and Intel GPUs in LLVM.

The focus on CUDA comes from the fact that most HPC systems for scientific computing are using Nvidia GPUs. That is finally slowly changing.

Exercise is all about routine. I have a very hard time getting into one when I work from home... I don't have a commute that brings me past a gym so I have to force myself out of the house to go to one 15-20 minutes away. I also like to work out after 11pm at night which is problematic in most gyms.

The Peloton is expensive, but the bike is very high quality and the whole family can use it with their own account... so I have 3 people using that subscription.
I get how ML works. I don't mean loops as a for(int i) loop, but the concept of a loop itself, a circle. A self-driven car with ML decision making is still bounded by some rules we will be forced to compromise on. Some people at MIT are focusing on deaths per miles driven as a safety metric to determine whether we can replace humans with ai cars and when that might happen.

But given the constraints of ML/ai you will eventually have a bounded container where an ai car can operate and where it can't. The car will be tasked with looping through that environment from job to job then back to recharge at it's base station. For all the sophistication of getting the car on the road and working it won't really be making up it's own story through the world nor will it understand the greater context of it's actions. The pattern recognition in CV is great, but it is fed by humans, so the meaning that a tree should be avoided has been initially put in by a programmer, even if the car in the moment chooses to avoid the tree by itself. The car is crunching meaningless numbers like a pipe directs water.

So when people say a machine "understands something" it can't ever really be true because all of our machines don't know what is going on in the world, they only know what numbers they see and how to behave when those numbers change. At the very bottom it's electricity looping through logic gates and that same principle is repeated all the way up to a car that loops through it's environment and comes back.

If all the humans left the planet, the car wouldn't be described as understanding the world, it'll be seen as a generic device sitting in a garage somewhere waiting for orders from a human. If you fill the earth with aliens the CV breaks not having seen aliens before, the roads get changed over time by nature, the high detail mapping it relies on fails. The cars "understanding" only exists as an outcome of electric impulse. It doesn't understand and never could. We are building more and more sophisticated loops, and I'm glad, but to think computers can understand is a doomed project. They will never "get" the values, intents and stories we put in them. Computers will forever be a labour of love is not able to regress into understanding what we mean it to be.
You Can't Kill These Gorgeous 'Preserved' Plants. Here's Why
I do not like Pelotom at all. Do not like Zwift either as their graphics sucks and view of bazillion animated cyclists around me does not add value either. I guess this is because I love cycling but do not really care about racing. For racing crowd I guess Zwift can make more sense.

I very much prefer software with so called Real Life Video (Tacx TDA, Veloreality, etc) for my indoor training in winter. The scenery is way more inspiring on big screen TV.

Comes summer, forget indoors. I love cycling and swimming in open water. No software would ever come even remotely close.

4. Statically sized stack frames (i.e. no VLAs or alloca)

Pick (any) three of them. You can't have all four.

Typical Fox News Clickbait / Yellow Journalism.

The real discussion is WHY do wealthy Californians have to do this?

The real answer: Because the federal government is robbing Californians blind. Trump himself acknowledges that we pay more taxes than anybody else, yet also threatens to take away FEMA "privileges" as if federal support is a gift, rather than something we overpaid for.

California pays $25,000,000,000 more to the "American" federal government than it receives in return. If we didn't have to keep paying for Trump's golf trips and wars on the other side of the world, and perhaps if the rednecks who populate republican states weren't all on welfare, then we could stop forest fires.

Unfortunately, the Republican establishment WANTS California to burn down. They're furious that we are the only real successful state remaining in the declining American empire.

Here's my perspective on this:

>If you have an identical twin, is your twin "as much you" as you are yourself?

No in pretty much all meaningful senses; there was never a point where you and your identical twin had the same memories.

>At the moment of replication, which of the two is really "you" (can anyone, including you, tell?), and how will that identity develop into the future as the two have divergent experiences?

This is where the concept of personal identity itself gets tricky. I would say that in a way both of them are you. As far as my subjective experience is concerned, what makes me "me" is primarily my memories, and both instances would share that at that point in time.

This also means that, as two instances exist with diverging experiences, their "identities" diverge as well.

An outside observer might view the original and the copy differently, but personally I view subjective experience as the most important factor here.
> Accessing a char value as if it were a different type just isn’t allowed.

Is this still bad if you have the proper alignment (by attribute or implicit placement in a struct), or have it wrapped in a packed struct? There's a lot of code that does this, e.g. overloading the definition of struct sockaddr.

>GUI do democratise access to capabilities, but unless you work only with pixels GUIs are inferior in every single way.

Except in the way that matters: symbolic representation and manipulation (and discoverability).

>Expressiveness is not limited to a medium, and if you ever used a command line interface you would understand the concept it pipes and arguments is way more expressive than a round of 100 clicks to do the same thing thru a GUI.

Actually, a GUI can trivially include a pipe system (tons of VFX and Color gradings apps for example offer one, MAX/MSP and others).

A GUI can also trivially include a text console, and have all the capabilities of the command line.

The command line, on the other hand, can't have all the capabilities of the GUI. Even auto-completion is implemented crudely with curses interfaces (which, in any case, are GUIs too).

(Oh, and I've been using the command line since the pre-Solaris days of Sun OS).

He is said to have been a fruitarian for some time during his youth, but not later.
Wow. And to think that his vision has now put a mini computer in the palm of millions of humans. The early competition of iPhone vs Android really sparked a ton of innovation and a culture shift.
It wouldn't be that much overhead in reality, you can still write the kernel in a mix of C and ASM (or more modern; Rust and ASM). The kernel doesn't even need to know about these isolation mechanisms, since you run stuff in ring 0, you can hook the appropriate APIs and interfaces in a process. The kernel itself would be insanely small and thusly more easy to defend.

Well, it doesn't have to be free from vulnerabilities, not any more than any other OS code. The sandboxed code that is running trusted (ie without trampolines and spectre-defenses) would still hold the guarantees given by the sandbox (WASM), which are pretty much on par with what a modern browser can do for JS and WASM. And keep in mind that both WASM and JS now have spectre-defenses, so there is no need for a PL from scratch for this.
Wreeto – A simple workspace to help you focus: markdown, wiki and data export
Original Author here, thanks for the feedback. I totally agree with most of the points made.

Right now, I wouldn't call it production-ready. It is too complex for non-coders and too trivial for actual developers.

I've been working on this for quite a while and I wanted to get something released so I wouldn't keep coding in my basement without feedback.

Right now, I'd say this tool is handy for Flutter beginners getting to know the layout system.

Addressing the problem regarding this being just a "Klickibunti" application.

I feel strongly about having this tool produce actual code a human developer would have written, therefore this could be considered the "groundwork" for future actually useful features.

Such features could include a full sketch integration that strongly connects to the actual widgets which work with different screen sizes and gesture behaviors.

One big feature which I've been planning for a while is a full 2-way code integration, meaning you'd be able to open up a random Flutter project in the widget-maker, tweak something and proceed with writing code.

Again, the points mentioned are very valid and I'm trying my best to build something which doesn't fall into the category of being a "nice idea that just doesn't work".
It's not guaranteed that they catch up to the US, even with such a massive population. Although they're growing at a faster pace the US economy is much larger, so that in absolute terms they're not currently gaining ground. Then you look at the US population which is still growing and closing that population gap slowly, while China will shrink 30 million in the next 30 years. At which point their demographic nightmare will be fully settled in with a very large retired population and a much smaller working class, worse than Japan currently is dealing with.

But the elephant in the room is does real innovation require freedom? So far China had been unable to come any where close to the US in innovation, and that's the major driver of growth for a developed nation. At some point they may just hit the wall.
