Yesterday I was listening to some music, but it didn't get saved to my account's history since it was blocked by an ad blocker. I was wondering if anyone knew if it was possible to access my recent history in another way.  My phone is rooted so I have access to the filesystem.  If anyone knows if/where/how my recent history might be stored, I'd appreciate it. If it makes any difference, I'm using the most recent version of Youtube Music (Vanced) on Android 11.
Could you list all possible directories where Android apps may store data, providing description what kind of data are stored in each directory?
Add time restriction in ArcGIS Network Analyst I'm trying to use train tracks as a network in ArcGIS Network Analyst.   We are trying to create a model for security agents on board our trains and we'd like to optimize their daily "route". For now, it's all made by hand.   My approach is to take our gtfs data and create a network using stop times to determine when the train segment is "traversable". When there's a train on the segment, it's open, if not, it's restricted.   The problem is I can't set a restriction based on time in Network Analyst (or wasn't able to). I would like to be able to say by a formula or script than you can take that segment only from 7:03 AM to 7:10 AM for example.  Is it possible?  Thanks! In Harry Potter, Do Spells Travel in a Straight Line? In the Harry Potter world, when a magical person casts a spell, sometimes they target a specific object, like when Harry has a wand only and needs his broom, he casts "Accio Firebolt" and his broom comes to him.  But a lot of the time people point their wands just in the direction of someone to cast a spell.  One example would be in a duel.  When they do this, are they casting a spell on a particular person or at that person?  It seems, from what I remember of the movies, that some spells travel in a straight line while others specifically target a person or object.  Do any spells travel in one direction, like a laser beam?  What kind of spells are directional (instead of focusing on a particular person or object)?  And can directional spells be deflected or blocked by something like a mirror or another physical object?  (By "directional," I could have said linear, but didn't want to start sounding mathematical or scientific.  In other words, do they travel in one direction, like a laser beam would, or will they change direction to hit the intended target?) I got a new laptop; it came with an existing Windows installation, but I wanted to migrate my current backup to the new machine. I dd-ed the new machine's partitions to an external drive:  /dev/nvme0n1p1 /dev/nvme0n1p2 /dev/nvme0n1p3 /dev/nvme0n1p4   and afterwards move my current partitions to the new machine. What followed was a medium-sized nightmare. The new machine would boot, but the wireless network drivers were not recognized and later found out (to the best of my knowledge) they couldn't be installed. I tried:   booting from the console and running:  sfc /scannow chkdsk C: /f /r /x   both seemed to have completed successfully, but now the machine would get stuck in a startup repair loop. I tried resetting the machine (whilst keeping my files), but this failed halfway through. now the machine's still stuck in the loop and decided to try and repair it externally using a bootable Windows&nbsp;10 . It's likely that I'll need the new machine's Windows&nbsp;10 key. I'm not sure if it's stored in the BIOS (it came with Windows&nbsp;10  preinstalled) or somewhere on the partitions.   How can I get the key from the partitions (if it's there at all) while booting from a Linux image? What does the double slash mean in `${f// /_}`? I'm learning Bash, and I want to replace space characters with other "non blank" characters. I'm using a for loop:  for f in *\ *; do mv "$f" "${f// /_}"; done   My question is, why are the double slash and the space in ${f// /_}? What does ${f// /_} do? How to make equally sized windows in corners of the screen? Sometimes it takes too long for the network manager to update to see new wireless AP. Is it possible to change the time interval between checks? Is a music band a singular or a collective entity, grammatically speaking? Duplicate:    What is correct to say?  Korn* is a great band  OR  Korn* are a great band.  (* You can replace your favourite band's name here) Of course everybody there is no doubt about the following sentences:  The Beatles are a great band Led Zeppelin is a great band  But with certain kinds of names, the situation becomes difficult.  Metallica are a great band  OR  Metallica is a great band  Is there any consensus on this matter? Comparison theorem for ODE The formal solution of the time-dependent Schrödinger equation Consider the time-dependent  (or some equation in Schrödinger form) written down as $$ \tag 1 i \partial_{0} \Psi ~=~ \hat{ H}~ \Psi . $$ Usually, one likes to write that it has a formal solution of the form $$ \tag 2 \Psi (t) ~=~ \exp\left[-i \int \limits_{0}^{t} \hat{ H}(t^{\prime}) ~\mathrm dt^{\prime}\right]\Psi (0). $$ However, this form for the solution of $(1)$ is actually built by the method of successive approximations which actually returns a solution of the form $$ \tag 3 \Psi (t) ~=~ \hat{\mathrm T} \exp\left[-i \int \limits_{0}^{t} \hat{H}(t^{\prime})~\mathrm  dt^{\prime}\right]\Psi (0), \qquad t&gt;0, $$ where $\hat{\mathrm T}$ is the time-ordering operator.  It seems that $(3)$ doesn't coincide with $(2)$, but formally $(2)$ seems to be perfectly fine: it satisfies $(1)$ and the initial conditions. So where is the mistake? Is "reserved" an adjective or verb in this example? I need an answer about this sentence please:     We had a reserved seat.   Reserved in this sentence is a verb. I read that in a morphology book.  My question is: how does this become a verb?  I thought it was an adjective. How can I play sound in Java? Was "book" to "beek" as "foot" is to "feet"? "Foot" is a curious word in English because it is pluralized in an unusual way; the "oo" in the word is changed to "ee".  Did this once use to be a standard way of pluralizing things in English (or a language that contributed to English), which would mean that the plural of "book" was "beek" instead of "books"?  Or, is "feet" just a one-off? In the double-slit experiment of electrons (observed by photons), is it correct to say the collapse is caused by the momentum of the photons? I'm working off the article, . I think it's well-written, but I'm not convinced about this part:     So what is causing the change in the particle’s behaviour?      In the example given above, when electrons are fired at a fluorescent screen, when we bombard the electrons with photons the interaction changes the state of the system catastrophically as, despite lacking mass, photons do carry momentum.   Here the author strongly implicates the momentum of photons as being responsible for the collapse. But is that correct to say?  I have read that the  verified that obscuring which-way information restores wave-like behavior. So it feels to me it's more about some "outer" state (perhaps well-characterized as "information") that we don't yet understand that collapses the system, not per se the photon-electron interaction.  Or am I wrong, and in fact for example, the process of obscuring in the quantum eraser experiments somehow "undoes" the photon-electron interaction or restores the quantum state through another interaction? This is the views section of the site analytics visible to 25k users on one of my sites:    That's, uh, not correct.  Our site has had its usual activity level during this time.  I checked a couple other sites, and the pattern is consistent.  This looks like a problem in the analytics data that's coming in; did Google change their API?  Update: Same site a week later; note that in addition to the brief spike of accuracy, page views have dropped to (near-)zero for the whole period, unlike the earlier report.  (I know this question has been closed as a dupe, but I thought having the two screen shots together might help somebody.) Flight Search from anywhere to a specific destination Many flight search engines allow you to pick a departure airport and search for flights to anywhere. E.g.  gives you a nice map with prices next to destinations for a set of dates and an origin you selected. We covered this question widely in  here on our site.  I want to have the reverse, i.e. I know my dates and my destination (for a one-way flight) and I want to know from where it is cheapest to fly there. Is there any flight search engine out there to achieve this?  Google flights does not do this, they pre-compile the "from"-field if I try to leave it empty. I know I could use  with a wide range of departure airports but that does not give me low-cost carriers and I do not trust the matrix results for such a wide range of parameters anymore.  Edit: It has been asked in comments why I would want such a feature. Well currently I'm planning my summer vacation and I would like to spend one week traveling around basically anywhere in that area before I have to go to a specific location at a specific time. One of the main price and convenience factors for me is that final flight so I would like to optimize it first. I'm sure I'm not the only one with that kind of constraints. I am trying to run an executable file from a network drive on Windows 7 Professional (64-bit) in order to install a program, but, each time I try, it doesn't run and the following message appears:  {path-name} The specified path does not exist. Check the path, and then try again.   I am definitely connected to the network drive as I can see all of the directories and files, and can even open non-executable file types. Also, I am fairly confident that this is neither a firewall nor a permissions issue. What is dconf, what is its function, and how do I use it? Mark Shuttleworth  about the decision to include the Qt libraries in the 11.10 release, with a  Jono Bacon. Mark states that the biggest challenge to integrating apps written in Qt into the larger Ubuntu system is Qt's current non-compatibility with dconf.  What is dconf, and what is the role it plays in Ubuntu? Is there a simple way of proving that $\text{GL}_n(R) \not\cong \text{GL}_m(R)$? Letting $\mathbb{F}_{1}$ and $\mathbb{F}_{2}$ be fields, and letting $n \geq 3$ and $m$ be natural numbers, it is known that $\text{GL}_{m}(\mathbb{F}_{1})$ and $\text{GL}_{n}(\mathbb{F}_{2})$ are elementarily equivalent if and only if $m=n$ and $\mathbb{F}_{1} \equiv \mathbb{F}_{2}$ (as proven in "Elementary Properties of Linear Groups" in the collection "The Metamathematics of Algebraic Systems — Collected Papers: 1936–1967").  So, given a field $\mathbb{F}$, if $n \neq m$, then $\text{GL}_{m}(\mathbb{F}) \not\equiv \text{GL}_{n}(\mathbb{F})$, and thus $\text{GL}_{m}(\mathbb{F}) \not\cong \text{GL}_{n}(\mathbb{F})$.  Letting $R$ be a commutative ring (with unity), and letting $n, m \in \mathbb{N}$ be such that $n \neq m$, is there a simple "algebraic" way of proving that $\text{GL}_{m}(R)$ and $\text{GL}_{n}(R)$ are not isomorphic (as groups)? Is there a simple group-theoretic way of showing that $\text{GL}_{m}(\mathbb{F}) \not\cong \text{GL}_{n}(\mathbb{F})$ for a field $\mathbb{F}$?  Certain special cases of this problem trivially hold, for example in the case whereby $\mathbb{F}$ is finite, in which case $|\text{GL}_{m}(\mathbb{F})| \neq |\text{GL}_{n}(\mathbb{F})|$.
