The two most obvious solutions to the thought experiment presented are either 1) space is absolute in some way (i.e. the classical Newtonian response) or 2) the behavior of space "here" is affected by the by distribution of matter "over there". General relativity gives us a strong argument in favor of (2) by showing that a) many physical principles thought to be absolute are actually relative and b) showing that mass "over there" affects the shape of space "here".

To say anything more concrete requires requires defining the question much more precisely. I believe there is still some disagreement on the interpretation of Mach's principle in light of general relativity. For example, see https://en.wikipedia.org/wiki/Mach's_principle#Variations_in... (and a couple sections above, the 1993 poll of physicists asking: "Is general relativity with appropriate boundary conditions of closure of some kind very Machian?"

I hope that is helpful in some way.
Information is actually about _reduction_ in entropy. Roughly speaking, entropy measures the amount of uncertainty about some event you might try to predict. Now, if you observe some new fact that has high (mutual) information with the event, it means the new fact has significantly reduced your uncertainty about the outcome of the event. In this sense, entropy measures the maximum amount of information you could possibly learn about the outcome to some uncertain event. An interesting corollary here is that the entropy of an event also puts an upper bound on the amount of information it can convey about _any_ other event.

I think one frequent source of confusion is the difference between "randomness" and "uncertainty" in colloquial versus formal usage. Entropy and randomness in the formal sense don't have a strong connotation that the uncertainty is intrinsic and irreducible. In the colloquial sense, I feel like there's often an implication that the uncertainty can't be avoided.
I'm not someone who has a problem with older games - I've gone back and had a blast with System Shock 2, Baldur's Gate, Mechwarriors 2/3/4, Thief, Planescape Torment, etc. relatively recently.

But Deus Ex is one of the few classics that I just can't get to click. It just feels too clunky and ugly, with a lot of the mechanics coming across as ...not to my preferences let's say. Even after I've completed the whole campaign two times over I still just don't "get it". As for the plot getting timelier, to be honest it still just came across as conspiracy gibberish to my ear. I dunno, maybe I'm just not smart enough for it.
Are there any activities that you enjoy doing for hours at a time without draining you?

You might want to use that as a starting point and then branch out.

Alternatively, it seems like you might be struggling with anxiety/impatience and you might want to work on that instead of trying to reorient your external life.

Some suggestions: try exploring mindfulness and meditation, it's pretty easy to get started with an app like HeadSpace. Also, I would highly recommend the book The Charisma Myth, it's pretty simple and has some excellent exercises to deal with a range of impairing feelings/emotions in an effective way.
What's hilarious to me, growing up in the era of swap, is that now you can have so much RAM that you can start caching your disk to RAM for a little extra performance (well, we've kind of moved past that, too, since SSDs are so much faster than spinny disks).
Is there any complaints you have with creditstacks?
If you have a specific question about electrical reactance, I can help. If not electrical, I probably can't help since I don't know what you are referring to.
My top 3 suspicions why this won't be added:

- The use case is consider too 'niche'.

- There is some concern that users will wipe their phones by accident and raise support tickets and/or engage in any other activity that causes additional work/cost for google.

- 1st party support might step on various governments toes by shipping this by default.
I honestly believe that they will not bypass any opportunity to increase surveillance and that any kind of tracking that is normalized now will be expanded in the future.

I don’t believe that the people pushing this knowingly have bad intentions, but all the last decades have taught is “never give an inch.”
Ask HN: What has your career looked like?
Since formally starting the area of work you are in now, what has your career looked like? I'm especially interested in people who have switched tech stacks along their career.

For me:

CS degree

Working in a non-tech company for 9 years. Java and SQL mainly.

Great! I'm glad Apple has changed its rules concerning having an embedded interpreter:

Try psychotherapy. It is not going to change anything immediately, but maybe you'll start looking at your problem from a different angle and find out that the problem is not your dayjob.

I've heard this referred to as "periapsis below mean radius" which is a euphemism for "the mission just ended."
Thanks.

I have no strong evidence, but it seems that Force 47 is actively monitoring my blog [1]. I've never got so many personal attacks and smear comments like I did since I published my findings. I bet one of them will cite your comment as an evidence of my "immaturity".

I always thought vertical partitioning meant to split by columns (that is, have fewer columns per table, and you need to join to get the original back).
note: I don't even dabble, and getting my info from [1] so salt

with Qualcomm, if I'm not wrong, it should suffice to, with FDE, (transparently, on entry of pin), nuke the DEK (random key generated by Keymaster), and force a device reset; this does seem like an interesting usecase for custom firmware and/or magisk

[1] http://bits-please.blogspot.com/2016/06/extracting-qualcomms...

albeit, if this does end up being implemented in some manner, wouldn't the fallback be a "confiscate electronic devices first for forensic" approach?
This is a surprising threat model:

> It would be great to have the possibility to set second pin code which wipe your device without confirmations. [...] In my country (Russia, if you interested) policy try to force political activist unlock their smartphones for collect more evidence. They use tortures and threats of tortures for this. If you you can't unlock because it wiped they don't have motivation to use tortures.

My mental model of law enforcement in the US is that they don't become less inclined towards illegal violence if you anger them. If anything, I'd expect a "clear this subset of data, but go ahead and unlock the phone anyway so it looks normal" feature to be more useful.

(So I guess I think that this feature request needs more detail/discussion in order to be useful.)
So the best way to solve this is to have an in-store map to find workers of the store so you can ask them.
I think a lot of people know that, but also a most people use one of a few email providers in their country.
Update: I fixed a mistake on how I was calculating R0 (I think it's correct now) and also adding some basic smoothing with moving average options.

With this approach the R0 estimations are always lagging, so the most recent estimate I have for NYC is for 4/4/2020 with an R0 hovering right around 1.0 - at that date growth was steady linear.

As new data on fatalities comes in, hopefully will see this decrease.
I'm not too sure it won't work, but I'm pretty sure it won't be efficient. Or maybe your plane will just rotate until the wings are horizontal again.
The reason I don't blog is because I would be tempted to delete whatever I wrote a week later
By contrast consider Conor Dougherty's Golden Gates: Fighting for Housing in America https://www.amazon.com/Golden-Gates-Fighting-Housing-America..., which is about how California in particular works hard to raise the cost of housing.

I am sorry but I don't get it. I read the formula and get the formula but that doesn't make it logical.

If you move away from a clock, time seems to slow down as your distance to the clock gets larger and the time between a change on the clock reaches you over a longer period. But if you carry a clock in your rocket it will just tick at the same pace as on earth (minus the gravitational impact, which is measured but why does gravity have an impact on time...?)
Docker is for containing the environment of your apps. NixOS is for configuring your operating system. I use NixOS to define which Docker apps run on my machine, as well as monitoring and administration tools, firewall setup, that sort of thing.

If all you do is apt-get install docker, that doesn't feel like a very complete set up to me.
In my experience this is untrue -- I've worked with many business processes that are very complex, and software hasn't even got involved yet.

More generally, the issue is that customers often do not understand which requirements lead to complexity, and which ones don't. If the software development relationship is transactional (and in Enterprise it usually is), then this leads to unmanaged complexity.

A lot of software (and processes) fail to have an "escape hatch" where exceptions are kicked out for manual intervention. Putting this in and then managing to the intervention rate is a decent way to manage complexity.
The issue with these animations is that they're getting rid of all the thermal noise. In reality, single proteins are flying around the whole length of the cell many times a second, just from their thermal motion. And when processes like DNA transcription happen, they're not like a regular conveyor belt -- a fraction of the time the machine will even accidentally run steps in reverse! However, if any of this were shown, the animations would become impossible to understand.
I'm trying to summarize my knowledge through my blog [0] (borrows some inspiration from Gwern) and also experimenting with sharing my private knowledge base and making it public [1].

Also, this is the most extensive list of others' wikis/knowledge bases I'm aware of: [2] Nikita's wiki is very cool and greatly inspired me.

I made mine public mainly because: I spent time curating and organizing this knowledge, and if other people can benefit from my curation for their project/learning/etc, this will ultimately benefit all of us, including myself. So in some sense it scales my efforts.

I feel like I've accumulated vast amounts of information, and some of it I'll never have time to properly process. However, I've already spent time curating it, so perhaps someone else can browse through my links and spend less time sourcing the information.

Another motivation is that I want to live in a world where I can tap into anyone's "public knowledge" and browser through it, without having to physically interact with them. Not that I don't like physical interaction, but it just doesn't scale as much, so we'll need something better in the future anyway. Public wikis are the closest we have to that future, perhaps.

I totally have the opposite experience in Québec. Everywhere and anything in Québec feels red taped and low of customer service. Maybe I have to speak French. Speaking in English and being non white gets a degraded service in Québec.
Working software isn't developed by the "implement all the features that you can't think of a reason not to implement" model.

The old MS blog post about "minus 100 points" is a good analysis of this: https://docs.microsoft.com/en-us/archive/blogs/ericgu/minus-...
this is a pretty good detailed explanation: https://fermatslibrary.com/s/how-airplanes-fly-a-physical-de...

the summary being:

- The vertical velocity of the diverted air is proportional to the speed of the wing and the angle of
attack.

- The lift is proportional to the amount of air diverted times the vertical velocity of the air

it also debunks the myth of "air flows faster on the top side of the wing, causing lift"
I am definitely in favor of looking for diversified opinions, from people with diverse backgrounds, some of them specialized in the field.
Diverse inputs are way more interesting than those of a single group of people with similar or homogenous background.

That being said. First, most people aren't qualified to have and give their opinions on most topics. Most of us are clueless dingbats when it comes to most things, including figuring out what makes someone fit to lead a country. Or a city.

Yet it was decided it was best to give us all a vote. Go figure ¯\_(ツ)_/¯

Second, opinions of outsiders have shown remarquable results in some fields. Such as Daniel Kahneman's (a psychologist, coincidentally) in economics. His insights lead to behavioral economics.

In that specific case, only someone having had their entire education and career in the field of economics, being indoctrinated by all those before them, could really believe people and organizations behaved even remotely like rational agents.
That this model was enough to make sense of the (economic) world, at any scale (on this topic, his book, "Thinking Fast and Slow", yields some remarquable insights on 'experts')

So, while I share in your desire for an increased quality and diversity in information, knowledge and opinions sources, please do 'put a little water in your wine'.
TIL that there is a "c.utf8". Thank you.

But my God, could this shit possibly be any more byzantine?

(And why doesn't LANG=C just cause c.utf8 to be used?)
Ahh ok. So let's say the HN gods don't bless my post with a hyperlink, what's the best way to do it? Should I put it in the comments?

Main reason I avoided the comments strategy was I felt it'd get lost in the sea and then people wouldn't know what the author's post is all about.
It's easy to blame the government too. How dare it run on old technology just because we under fund and expect it to fix all societies problems.
WP is accessible to the masses who just want to publish. It's not the pretties, but most people once set up can get it to do what they want it to do and start playing around with stuff.

Generally speaking, the HN audience is not the typical audience we have at StartABlog.com, but WP "just works" well enough for most people.
It took _forever_ to get a self-hosted Jabber-based chat client going at a mid-sized corporation, about 10 years ago. Someone went “rogue” and set a server up anyway. Our security staff began blocking ports, so it eventually died anyway... in favor of Skype and Yammer. All because no one wanted to host chat history and a server.
I can't imagine Google ever implementing that feature request. Apple had a PR nightmare after not unlocking a phone. Imagine the fallout if Google made it easy to quickly hide evidence from the authorities. It would be a legal and PR disaster, with the risk of having oppressive governments ban all Android devices.
I think the "obselete" part is the issue being open from 2018.

@ parent, it doesn't really seem like the title is "misleading" given we know the feature does not exist. although some might wonder if it did, so /shrug.
Well, I'd recommend to read the whole series. It's not so bad as it sounds. There are so many steps from where you are to appreciating the utter weirdness of Bell's experimental result. Not the weirdness of any theory (or an interpretation, which Many Worlds actually is) but of the basic experimental result.

If you are properly amazed by it, rejecting MWI or any crazy-ish borderline-conspiracy theory seems suddenly a lot harder.

I feel the whole Yudkowsky's QM series in fact served to deliver that one post.
I thought this was already established for a while now
Firstly, it is not normal in the open source world. Hell, it's not even normal open source projects owned large companies that are the foundation for a major product - like Android. Secondly, as the story points out, it is a fork of an open source app that is already on github. It's not like the infrastructure for it isn't already set up - they just had to do a git clone, and then use standard CI techniques

Maybe the OP isn't familiar with the modern software engineering techniques we now use to improve quality.
I was secretly hoping for it to be GarageBand, which I only discovered a few weeks ago after apparently having it on my phone for several years now. It's a fantastic little app that does things I couldn't have dreamt of ten years ago. I've been writing pieces of songs, which is something (at 41) I've never done before.

But no, this is basically chat roulette 2020.
This is definitely related, though not the whole story. Quantization did get rid of some infinities, but as GP kind of states, it also introduced others. My comment focuses on what we do for those.
Marketing speak. Do you work there ?
Ask HN: Should I create several small projects or one medium-size project?
I would like to demonstrate my understanding of different subjects like graphics, systems, networking, web, machine learning, and algorithms. If you were hiring, would you recommend someone have in their portfolio several toy projects or one large project showcasing all of the skills in unison? It seems my peers have taken the former approach, making public their experiments and copy-paste "hello-world" type SPA applications under fancy names and banners. I feel like this is largely a waste of time because hiring managers don't care about how well you can write chat application clones in different frameworks -- am I wrong?

I spend weeks evaluating and learning different technologies but I rarely if ever actually make these experiments public. Sometimes I create full applications but end up deleting the source code because they don't seem valuable enough to keep or share. I mean, why should I push yet another project that few people will ever use or want? They really serve no purpose other than indicating that I had enough time to perform an intellectual exercise.

Should I be making my experiments public for exposure? Would anyone believe me if I said I had experience with technology X but had no public code to show? I currently spend my time working on a single project composed of several smaller modules. I enjoy writing tests and documentation for it, cleaning its commits, and just making the whole thing presentable and high-quality. But if spending my time on a single idea is going to negatively affect my ability to find gainful employment, I think I should just stop preemptively, no? Maybe I could start by porting https://github.com/bradfitz/iter over to Rust.

I'm not really smart enough to quickly pump out dozens of high-quality projects and so I'm getting anxious because the market is struggling and my portfolio is looking... very bare. Honestly the anxiety is making me wonder if I should give up on software development altogether.
Bought a Vive and new RTX card the first week of realizing I’d be stuck at home for months. Almost all of the other headsets were (and still are?) sold out.

I bought in with the expectation that I could have a great social experience in virtual reality, but it really hasn’t met up to my expectations. Virtual reality is cool, but the VR social networks are really lackluster.

First of all, the audience is typically very young. There are far more children than I had expected. Don’t expect to have a good conversation right off the bat, and it will take a while to find someone of similar age/maturity and interests.

I’ve hopped around a bit between AltSpace and VrChat, and I think I prefer the AltSpace crowd a bit more.

What I haven’t yet done is participated in structured events. Seemingly, you can find every thing from open mic night to meditation and movie night. I got really interested in this aspect by watching a channel on YouTube called Disrupt. (The same guy who spent a week in VR)

I think I’m going to give bigscreen a try tonight with the premiere of Jackass 3 in 3D.

Being generally new to VR, I largely thought the claims of motion sickness were overblown, but quickly realized how fatiguing VR really is.

As far as socializing these days, I’ve found luck with good old plain video chat. None of my friends have heavily invested in VR yet, but we still manage to hop on multi-hour long video chats and catch up on things or work on projects.

And as far as meeting new people, I’ve found luck in playing team based mmos in my free time. You’d be surprised how well a common objective can do you in meeting new people. Once you find team members you like, stick with them. Steam and Discord is particularly good at this.

I also think that’s the failure of social networks in VR. Without a common objective or expectation, it’s really hard to have a good conversation. At least in a game, you can always resort to talking about strategy and the like. Conversation usually comes naturally after.

My take here is that VR is only really a good medium for interacting with people you already know, but this requires buy-in among your existing friends. Meeting people in VR is much less satisfying than traditional routes.
My hunch is that the science is not quite out on it yet and that the intuitive explanations are not accurate.

For example, see "Some recent developments in bicycle dynamics" (2007). Especially the folklore section:

"The world of bicycle dynamics is filled with folklore. For instance, some publications persist in the necessity of positive trail or gyroscopic effect of the wheels for the existence of a forward speed range with uncontrolled stable operation. Here we will show, by means of a counter example,that this is not necessarily the case.

I'd find it more strange if something did interest people for over 40/50 years. Trains for example - that's a long time to be interested in trains!
This sounds like a decent project for a student that could be contributed to something like Lineage OS.
Would anybody be interested in setting up a bounty? I'm thinking first team to show a major break in privacy wins the pool. I'll put in $100, and I hope others do too.

Edit: to be explicit, I'm talking about REing the app locally, nothing server side
Nearly all of the major tech companies are walking a fine line with respect to "warrant-proof" tech products in the eyes of the current administration of the US government.

Building a feature like this would be tempting fate given the current climate at the AG's office IMO.
I recently started taking insulin. Check out the molecular structure for that. It blows me away how complex it is.
> As anecdote, I'm drinking about twice as much, not exercising at all, canceling dental cleanings, and wouldn't go into a medical setting short of something obviously life-threatening.

This might be a life-stage or life-style thing, but this is probably the healthiest I've been in a long time. I have to be intentional with all my food, so I'm eating almost literally perfectly (though god do I miss restaurants...), and weed fits isolation or zoom hangouts in the way that alcohol fits in-person social events, and is _way_ healthier. And I've had multiple friends my age (late 20s) guiltily admit that this pace of life just feels a lot healthier mentally.

That isn't to say that the psychological challenges aren't sometimes significant, and I have gone from a 4x/wk gymgoer to struggling a little with consistent exercise. And the example of deferring medical care is a good one. But I just thought I'd share a counter-anecdote to the anecdote driving your assumption that being locked-down is necessarily net unhealthy.
> another benefit to slack is you can come back to it and see the history

As long as you pay the price.
