Stack Exchange sites are useful for providing an indication of quality of answers and questions via votes. But what about using the voting system to assess the quality of pre-existing resources? I envision this as working almost like the (admittedly imperfect) system of  in academia, but with better incentive structures and transparency.  To put this in context, I'm looking to set-up a site to bring together knowledge on appropriate technology into a single site and was wondering if the SE approach or something similar would be suitable. What we need is some sort of 'peer review' for online 'instructables' type plans and a community forum to ask questions and discuss things. I've set up a  in Area 51, I was told about this: "We want to be a knowledge base, not a link directory".
Stuff like polls, recommendations based on subjective constraints, puzzles, webcomics etc. do not belong on the serious main SE sites, where professionals should be considered at work and having just a few spare minutes ("code's compiling") to answer questions, so they should not be distracted by such things. However, I'd also like to have a home for these things still using the SE engine. For the reason I mentioned before, this needs to be a separate place though. Let's call it four.[sitename-here].com.
Transit in LA after 90 days in North America under VWP/ESTA I am from NZ and have spent 90 days in the USA with an ESTA visa waiver, and I am going to Canada before returning to NZ. My return flight is from LA but I have already used my 90 days of my ESTA and have not technically 'left' North America (Canada apparently doesn't count). My question is, how do I catch my return flight from LA? Can I get another ESTA even though I haven't left North America? How many times can I benefit from Advantage if I attack multiple times while not seen? A hidden ranger with Extra Attack attacks a surprised creature. Do both attacks benefit from Advantage, or just the first one?  If the ranger used Horde Breaker on another creature, would this attack benefit from Advantage? How to draw simple table Curve Bevel function, scale? If $n^c\in\mathbb N$ for every $n\in\mathbb N$, then $c$ is a non-negative integer? Supposing that a real number $c$ is given, is the following true?  "If $n^c$ is a natural number for every natural number $n$, then $c$ is a non-negative integer."  Though this seems true, I can't prove that. Can anyone help? Refreshing open attribute table in ArcMap using ArcPy rather than ArcObjects? I am running the Calculate Field GP tool from the arcpy in ArcMap. When a row value is updated, it does not show up untill I use the Reload Cache tool (Table Options > Reload Cache). How do I refresh the attribute table automatically without using ArcObjects?  I have tried updating the definition query as @blah238 suggested , but this doesn't help. Resetting the data source is not an option because the feature class might be in the editing session and I don't want to lose the connection to the source data. I have a laptop which I'm going to return due to battery defects. As I have already configured everything on this laptop, I'd like to migrate the installation on the new laptop (when I'll get it). The one to replace has a 128 GB eMMC, and two USB 3 ports. So, I was thinking to   Boot from a Linux live USB from port 1 Make an image with dd of the eMMC, saving it to a external HDD on port 2 Do the reverse on the new laptop   My question is, will it work fine with Windows? Does migrating this way have any issues? Would I be able to restore the installation if the new laptop is a different model with at least 128 GB? Provisioning Profiles menu item missing from Xcode 5 Accessing variables from other functions without using global variables I know we can use both Present Simple and Present Continuous to describe future actions. But I don't know when to use the correct form.   For example:  We fly to Paris next week.  We are flying to Paris next week.   These sentences both seem correct to me.  Can anyone explain me how to correctly use these tenses? What is $\int_{-\pi}^\pi \cos(nx)\cos(mx)\,dx$? Three files have suddenly appeared in my home directory, called "client_state.xml", "lockfile", and "time_stats_log". The last two are empty. I'm wondering how they got there. It's not the first time it has happened, but the last time was weeks ago; I deleted the files and nothing broke or complained. I haven't been able to think of what I was doing at the time reported by stat $filename. Is there any way I can find out where they came from?  Alternatively, is there a way to monitor the home directory (but not sub-directories) for the creation of files? Do I need to activate the firewall? I only use Ubuntu for a home desktop use? I am a novice at Ubuntu (12.04).  I have it on my netbook which I use mainly for surfing the net, learning python and remote desktop into my work computer.    Do I need to enable a Firewall type software?  If so, what would you suggest, and what are sensible default suggestions? Movie about gene therapy and genetics-based jobs I saw a movie several years ago and I have not been able to find it since.  It was about a dystopian society where parents could modify the genes of their children before birth.  Some individuals, including the protagonist, had not had this done, and so had a somewhat inferior genetic makeup.  Jobs are based on the results of genetic tests, and the protagonist, a male, was slated for a less than ideal job. In the movie, he fakes his identity and has major surgery to make him a little taller to match his ID. He is trying to get his dream job (astronaut?).  The only other parts I remember are   the protagonist, to keep up the ruse, managing to run on a treadmill faster than his  genetic limit a very suspicious character pulling the protagonist's DNA from a hair left in a comb By accident, I used rm on a file I didn't want to delete. Is there a way that I can get it back under Linux? Expectation of Exit Time of Brownian Motion from Interval I am trying to solve the following:  Let $W_t$ be a brownian motion and $a,b &gt;0.$  Define $\tau$ to be the exit time of $W_t$ from $[-a,b]$, that is $$\tau = \inf\{t \ge 0\ :\ W_{t}(\omega) \notin [-a,b]\}.$$  Show that $\tau$ is integrable and compute $\mathbb{E}(\tau)$.  I have seen this stated without proof multiple places that $\mathbb{E}(\tau)=ab.$  What is the logical argument that backs up this statement?  How are we guaranteed $\tau$ is integrable? Where should the apostrophe go on a possessive abbreviation? When expanding an abbreviation in parentheses, sometimes the thing that was abbreviate was used in a possessive context.  Consider the following example:     If the Giant Ostrich Bomb's (GOB) fuse is too short, you may be too close when it goes off and you may get kicked in the face.   Is the above correct, or should it be rewritten this way instead:     If the Giant Ostrich Bomb (GOB)'s fuse is too short, you may be too close when it goes off and you may get kicked in the face.   If this is a matter of style, do any of the popular style manuals have a recommendation? GNOME: disable sleep on lid close Is it possible to stop my laptop going to sleep when I close the lid?  GNOME 3.20, Fedora 24.    My laptop does not reliably wake from sleep.  (It happens to be a hardware issue... I think I basically killed it while trying to replace a wifi card.  But I want to keep using it for a while longer). Sufficient conditions for $x, Ax, A^2x, ...$ being linearly indepedent What is a good Hash function? I saw a lot of hash function and applications in my data structures courses in college, but I mostly got that it's pretty hard to make a good hash function. As a rule of thumb to avoid collisions my professor said that:  function Hash(key)   return key mod PrimeNumber end   (mod is the % operator in C and similar languages)  with the prime number to be the size of the hash table. I get that is a somewhat good function to avoid collisions and a fast one, but how can I make a better one? Is there better hash functions for string keys against numeric keys?
