Hosting options for people that have Imgur blocked by their ISP What is the "maybe" caller id suggestion in the call log based on? I got a call from a phone number that is not stored in my address book, and in the call log, under the number, a name was suggested: "Maybe: X" (where X is the guessed name).  Where is this guess coming from? How can I programmatically create a new cron job? I want to be able to programatically add a new cron job, what is the best way to do this?  From , it seems I could dump the current crontab and then append a new one, piping that back into crontab:  (crontab -l ; echo "0 * * * * wget -O - -q http://www.example.com/cron.php") | crontab -   Is there a better way? combine 2 fields in 1 to use it in the "group by" section of the reports is it possible to combine two fields in one and use that field to group by in reports? for example, i would like to combine ee id and ee name fields in 1 and show as 1 field in the "group by" section on reports. UK Standard Visitor visa application to sit for PLAB 1 without savings or job Subscribe to tags I am interested in? How do I subscribe to the tags that I am interested in?  I like to get notified via email or so, when someone asks new questions or if someone responds to my questions. Prove if $|a_{n+1}|/|a_n| \leq |b_{n+1}|/|{b_n}|$ and $\sum |b_n|$ is convergent, then $\sum |a_n|$ is convergent How to remove edit from edit queue? I asked a question on SO:  and got an answer that, while good, I thought could be improved with a minor edit:   After a little while, a comment on the answer showed me that I was wrong to have edited the answer.  How do I undo it? Equidistant points across Bezier curves Padding trailing whitespaces in a string with another character I'd like to output hello world over 20 characters.  printf "%-20s :\n\n" 'hello world!!'  # Actual output hello world!!        :  # Wanted output hello world!!========:   However, I don't want to complete with spaces but with "=" instead. How do I do that? To be truly standards-compliant, must all functions in C (except for main) have a prototype, even if they are only used after their definition in the same translation unit? Error 404 : While using flag Show that $\partial_\nu T^{\mu\nu} = - j_\nu F^{\mu\nu}$ In a theoretical physics homework problem, I have to show the following: $$\partial_\nu T^{\mu\nu} = - j_\nu F^{\mu\nu}$$  Where $T$ is the Energy-Momentum-Tensor, $j$ the generalized current and $F$ the Field-Tensor. We use the $g$ for the metric tensor, I think in English the $\eta$ is more common.  I know the following relationships:   Current and magnetic potential with Lorenz gauge condition: $$\mathop\Box A^\mu = \mu_0 j^\mu$$ Energy-Momentum-Tensor: $$T^{\mu\nu} = \frac1{\mu_0} g^{\mu\alpha} F_{\alpha\beta} F^{\beta\nu} + \frac1{4\mu_0} g^{\mu\nu} F_{\kappa\lambda} F^{\kappa\lambda}$$ Field-Tensor: $$F^{\mu\nu} = 2 \partial^{[\mu} A^{\nu]} = \partial^{\mu} A^{\nu} - \partial^{\nu} A^{\mu}$$ d'Alembert operator: $$\mathop\Box = \partial_\mu \partial^\mu$$ Bianchi identity: $$\partial^{[\mu} F^{\nu\alpha]} = 0$$   So far I have set all the definitions into the formula I have to show, but I only end up a lot of terms from antisymmetrisation and product rule. I also drew all what I have in , but I still cannot see how to tackle this problem.  Could somebody please give me a hint into the right direction? Continuous function from $(0, 1]$ onto $(0, 1)$? I plan on building a computer with  which has no GPU:     Graphics Specifications      Processor Graphics:   None   on a  motherboard which has an onboard integrated graphics processor:     Integrated Graphics Processor:         1 x D-Sub port, supporting a maximum resolution of 1920x1200@60Hz   1 x DVI-D port, supporting a maximum resolution of 1920x1200@60Hz   1 x HDMI port, supporting a maximum resolution of 4096x2160@24Hz or 2560x1600@60Hz   Support for up to 3 displays at the same time   Maximum shared memory of 512 MB      I have asked  and know that even if the CPU has no GPU, I can still get video as long as the motherboard has onboard graphics. However, when I went to buy the parts at a computer center yesterday, the technician said motherboards nowadays use CPU's GPU to display, including this Gigabyte GA-Z97X-UD5H motherboard (which he meant this board has no real onboard graphics).  So for Xeon E3 1231v3 + Gigabyte GA-Z97X-UD5H to display, do I need a video card or not?  (I don't really care about the graphics quality. I use the computer mostly to write programs, web browsing, and Photoshop, and seldom play games or watch videos.) Converting ArcGIS layer style to Styled Layer Descriptor (SLD) file? I am putting together a GIS server using GeoServer and need some help with importing my layer styles from ArcGIS 10 to  format.    I have one layer in ArcMap properly symbolized and labeled, how can I get this layers symbolization and labeling into a SLD file? For any prime number $p$, let $A_p$ be the set of integers $d\in \{1,2,\dots, 999\}$ s. Then what is the cardinality of $A_p$? How to get the file name and a line number of a function call? Is there a word for someone with the same name? If a person shares my name, in Dutch there is the word &quot;naamgenoot&quot;, meaning roughly 'member of the same name'.  John A: Hi, my name is &quot;John&quot;  John B: O, then we're insert solution word here!  Similarly,  'classmate' is 'klasgenoot' in Dutch 'roommate' is 'kamergenoot' in Dutch  I'm pretty sure I cannot call someone with the same name as mine a 'namemate' :)  Edit Because sceptics appear to be frustrated mightily by an apparent lack of research, there was  in chat, with no satisfactory conclusion. /Merriam Webster namesake appears to be linked to intentional name correspondance (being named after someone). There may be a US/UK English divide there.  &quot;I was named after my grandfather. I am his namesake.&quot; -   Also, the introduction seems to hint at much broader meaning:  &quot;Namesake is a term used to characterize a person, place, thing, quality, action, state, or idea that has the same, or a similar, name to another&quot;   Do you know of a better word/phrase to describe this succinctly? In English, especially in a poetic description, ships and cars are  referred to as "she".   Maybe their owners compare their beauty and elegance with those of women, but what if a female owner wanted to describe her yacht or car?   Would she also say, "She is a real beauty", or it might be "he" then?   Does the choice of a pronoun depend on whom she is giving the description of it to — a man or a woman?  What about a man-o’-war or a merchantman? Being ships, are they also referred as "she"?  P.S.  on the use of "she" in reference to ships, but there seems to be no answer to my question there.  P.P.S. My question wasn't pulled out of a thin air. I came across a book by a prominent Russian linguist, G.Veichman, written in 1990, (Novelties in The English Grammar is my translation of the title), where I read that the rule of personification of vehicles may be added regarding a female owner talking about her car using the preposition "he". Period. No further explanation or reference examples.
