The Barbarian's Rage ability gives advantage on Strength checks and saving throws.  Does this mean that the Barbarian gets advantage to attack rolls as well? Is an attack a check, or since saving throws are mentioned, that means it does not apply to attacks? How to check if my eSATAp port provides 12V power? I have a Lenovo ThinkPad Edge 13" model 0217-2QG with eSATAp port.  How do i check if my port provides 12V power (enough to power a 3.5" HDD)? Check variable equality against a list of values Story of lost tech but magic manifests I'm looking for this novel (or maybe a series of books?). I remember that technology began failing all over the world. Some people began transforming into different types of mythical creatures, like sprites, demons, etc. There was a band of about four travelers that were trying to make it to Chicago, since that seemed to be at the center of the issue. The story line frequently shifted the point of view in each new chapter. I vaguely recall a final battle in Chicago with an enormous and powerful demon creature. I think this demon used to be a corporate lawyer or big business guy before his transformation. I believe I read this in the early/mid 2000s, and was likely published around that time because of the types of tech used and failing in the story. Although it bears some surface similarity to the TV show, Revolution, they aren’t comparable in plot or characters. Does there currently exist a free online service that accepts a file, hashes it, takes an authoritatively chosen timestamp (from one or more time services), signs these and sends this signed message back? E.g. a digital notary, but only with regards to the timestamp and not the validity of the content as legal notaries might be obligated to guarantee.  Such a service might have an extremely simple API: Simply wget http://service/&lt;checksum&gt; and receive a signed message containing one or more timestamps and the checksum. The emphasis would be on the type of authority who might make such a service.  Edit: Although the original question did not emphasise the following, the Bitcoin-based timestamping services provided below do not rely on one authority, but rather the entire Bitcoin network. They can be seen as tamper-proof and verifiable without the help of the service that helped you sign it! Prove that for any piecewise smooth curve it is possible to find the parametrisation $\phi$ that is consistent with its length, ie.  length of a curve segment between $\phi(a)$ and $\phi(b)$ is equal to $|b-a|$.  It seems intuitive, but I don't have any idea how can I show this in the formal way. When I login to my ubuntu system, it show me this this message, How can I see it any time? I tried to run . .bashrc but it didn't worked.

Last login: Mon Jul  8 17:47:05 2013 Zero-pad digits in string Show $f$ is analytic if $f^8$ is analytic This is from Gamelin's book on Complex Analysis.  Problem: Show that if $f(z)$ is continuous on a domain $D$, and if $f(z)^8$ is analytic on $D$, then $f(z)$ is analytic on $D$. (I assume the intention is that $D$ is nice, i.e. open and connected)  I'm not exactly sure how to approach this. I'm guessing it has something to do with zeroes of $f$. For example, around non-zeroes, $f$ is analytic since $z^{1/8}$ is nonzero in a neighborhood. Or something along those lines. The details are eluding me.  Any help would be appreciated! Network simplex method, leaving and entering variables How to add Lat/long columns to a point layer which is not in WGS84? I need to extract the Lat/long coordinates of the centroids of districts. My QGIS project SCR and the different layers have all been set on "WGS 84 / UTM zone 18N".   I've created the centroids using the usual tool. I could then extracted the coordinates using the "Vector > Geometry Tools > Export/Add Geometry Columns", or saving the layer in CSV typing "GEOMETRY=AS_XY" in the "Layers" part of the "OGR creation options".  Nevertheless, both methods output Cartesian coordinates, whereas I need Lat/long coordinates. Why should the first person pronoun 'I' always be capitalized? Why should we capitalize the first person pronoun 'I' even when it does not appear at the beginning of a sentence? Why is it not the case for other pronouns? Should Luke's lightsaber have given away his plan? During Luke's confrontation of Kylo Ren toward the end of The Last Jedi we see that       the lightsaber Luke uses a blue lightsaber (which I thought was his original one but that really doesn't matter), not the green one of his own construction.   Given that Kylo Ren  and Rey has just     fought over and broken the blue lightsaber   Why did Kylo Ren not notice this "inconsistency" and realize that      Luke's physical body was not there? ‘ld: warning: directory not found for option’ Per line text gradient (ala beeline reader) Making overview with linked detailed maps in QGIS? i want to create 4-5 detailed maps, and then an overview map that has rectangles that markes the locations of the detailed maps. Best case would be if the rectangles were links to the detailed map.   I have managed to make the overview and the rectangles, and think I know how to make the detailed maps one by one. The rectangles are drawn manually on the overview map. All layers that I plan on using are in the same QGIS project.  The final product that I hope to create would be the overview map on the first page, followed by the detailed maps. The overview would have links to the detailed maps, click on the rectangles to open the right detailed map.  Is there a way to link the detailed maps to the overview in QGIS 2.8 print composer?  I'm still not sure if I'm doing something wrong, when I try to create the overview. I want it to show the extents of all of my detailed maps.   Is this possible? Is there a way to open a raster that is stored in ESRI V10.0 Geodatabase in QGIS V2.4?    I can open the vector layer, but there does not seems to be a way to open a raster. Adding Arabic text to an English document I am running Ubuntu 16.10 on a MacbookPro and keys 49 and 94 are inverted... I resolved this problem with xmodmap, but this won't apply permanently. After some research I found xmodmap is no longuer use by Ubuntu but xkb instead. So I searched in the configuration of xkb and I found in the config file /usr/share/X11/xkb/keycodes/macintosh this lines :   xkb_keycodes "badmap" {     &lt;TLDE&gt; =  94;     &lt;LSGT&gt; =  49; };  xkb_keycodes "goodmap" {     &lt;TLDE&gt; =  49;     &lt;LSGT&gt; =  94; };   This is exactly my problem, this two keys are inverted. So I wondering if I can't change my layout configuration with the param badmap.
