Why do we yawn? I've read a new study which suggests that yawning may help you keep a cool head. Also, the findings might hold some hope for sufferers of insomnia, migraines, and even epilepsy.  Is there any conclusion about what the function of yawning is and why do we yawn? Vehicles required/allowed in weigh stations on US interstates Is it possible to access a static resource of a managed package in your local environment?  Thanks I have 41 GB of space on my E:/ drive. Is it sufficient to install Ubuntu? My Windows XP is installed in C:/ drive. Is it OK for dual boot? Should I install Ubuntu (I am installing using Live CD). I don't want to lose my Windows option. After update, my Thunderbird stopped getting minimized with the "MinimizeToTray revived" add-on. Is there any way to minimize my Thunderbird? Any other add-on that works with the new version? Can't operator == be applied to generic types in C#? How to use mirror ball to light a scene? Plot draws list of curves in same color when not using Evaluate align vs equation I always use align in my documents, and avoid equation. Is there anything wrong with that? My reasoning behind this: align > equation, so why not use it? Can I vent my dryer into the crawl space without creating mold and moisture problems? We have a crawl space with a combination of sandy and clay soil in it.  The crawl space is about 3' deep.  To eliminate a long dryer vent run, I'd like to vent the dryer directly into the crawl space.  We have vents built into the foundation that I open each spring and close in the fall.  Will this help dissipate the moisture enough to prevent mold? Sneak Damage multiplier: Does it apply to magical damage too? Example:   Dagger 1 = 18 Damage, 25 Shock  Dagger 2 = 33 Damage, no magic  Using the above, when I sneak attack and have the 15x multiple then is the damage caused by Dagger 1 is (18+25)*15 or (18*15)+25 ?  Same question with bows and arrows, does the multiplier apply to potion damage or/and the magical(enchanted)?  In other words, do the multipliers apply to the base damage only or to the final damage being caused by the weapon (base+magical+skill+potion+perks etc)?  I am confused. :-? No matter what I do I'm stuck with &gt;. How can I enter a new command?  $ chmod -R 600 `/ .ssh &gt;  &gt; chmod &gt; id_rsa.pub &gt;  &gt; sudo chmod 600 ~/ssh/id_rsa     I was trying to sync the master and slave by following a youtube video when I encountered the "permission denied" issue. While trying to resolve it I got stuck with &gt;. Now I can't enter any new command.   Please guide me. I'm a Linux/AWS newbie. When I log in with LightDM on my laptop running Debian Unstable, it recently started to hang for around 2 minutes until journalctl shows the message kernel: random: crng init done. When I press random keys on my keyboard while it hangs, it logs in faster (around 10 seconds). Before I didn't have this issue, is there any way I can fix it?  Edit: using linux-image-4.15.0-3-amd64 instead of linux-image-4.16.0-1-amd64 works, but I don't want to use an older kernel. SQL IN Clause 1000 item limit How long should it take to refresh a Developer Sandbox? I refreshed a Developer Sandbox, and almost 24 hours it is still "pending". Is this normal? Are there any actions I can take to speed up the process? When I created the Sandbox it took barely more than 10 minutes to create.  Thanks, Adrian Possible Duplicate:          I was wondering if there's any good reason to still use blob fields in a database. A couple of years ago I worked with a DB with a bunch of images in it, the DB was very slow and I couldn't see any good reason to keep the images inside the DB, so I got the images out and stored the filenames instead.  Was this a smart move? What would you do in my place? Suppose $G$ is a semigroup and it holds both left and right cancellation. Suppose $G$ is a semigroup and it holds both left and right cancellation. Also for each $a,b\in G$, $xa=b$ has solution in $G$. Prove G is a group.   I know this question looks very "old" style. First I think it's easy for me too since I already practice probelems like "semigroup, $xa=b$ and $ax=b$ have solution , then group" Or "finite semigroup, both left and right cancellation hold, then group ". But I still get stuck... My try:  First of course, for $xa=a$ , there exists $e_a$ such that $e_aa=a$. Now we need to proof $e_a$ is left identity for all elements. Then left inverse exists hence $G$ is a group. But the key is to proof $e_ab=b$ for all $b\in G$. Is there any actual written dialog for the astromech droids? When R2-D2 and BB-8 converse in The Force Awakens for example, is there any written record of what the two characters were saying to each other?  I mean actual dialog, if it exists, and not something like ”BB-8 beeps excitedly”. The difference between GPU and CPU I know what a CPU is(I think). It's the thing who's speed is measured in GigaHertz(these days).  However, you hear a lot about a GPU, and letting the GPU take over, not letting the CPU but the GPU do it, GPU-based rendering, etc...  What is this GPU anyway? How can I access it and use it to my advantage? What am I missing out on here? Finding center and radius of circumcircle Find the center and radius of the circle which circumscribes the triangle with (complex) vertices $a_1,a_2,a_3$. Express the result in symmetric form.   I'm not sure where to start in this question. The circumcenter is the intersection of the perpendicular bisectors, but I don't know how to calculate the line equation of the perpendicular bisectors yet. As for the radius, after we find the circumcenter $c$ we can calculate it using $|c-a_1|$ (or $|c-a_2|$ or $|c-a_3|$; all three should be equal.) So how can I calculate the circumcenter?
