There is a lot of posts that are 'deprecated'(Correct at that time, but not today). Eg, Google maps v1(not available these days).  The problem with these is that, many developers(especially newbies) may depend on those deprecated solutions causing error and loss of time.  So, My opinion is, deleting those posts is not fair but, flagging as deprecated will be very helpful.   Feature request:- flagging>>Deprecated
I was viewing some old posts on Stack Overflow (two-year-old posts) and found that due to "fast technology trend changing," some of them are no longer valid. Stack Overflow (and the Stack Exchange sites generally) should have some sort of criteria to tag questions as Obsolete, or a vote-based system to mark them as such.  I am not in favour of closing obsolete questions.
Javascript multiple replace I am trying to take pictures of large rugs. The rug size is about 10mx5m, and I'm  planning to purchase , and Canon 7D Mark II with Canon EF 50MM F/1.2L USM lens, since we need high quality images.  We want to set up a studio to take giga-pixel quality images of the large rugs for museum conservation purposes  Could you please suggest the best way for mounting the camera to the ceiling, and any other recommendations for my camera/lens setup, and required lighting? It will be  an indoor shoot. Just we want to setup a studio to shoot the large rugs. Finite Summation of Fractional Factorial Series How to get Saudi Arabian transit visa for road travel? I use Ubuntu 18 and have little experience with Linux commands. I have two files:  file 1:  a,txt1,v1 b,txt2,v2 c,txt3,v1 d,txt4,v2   file2:  a,txt5,v2 b,txt6,v1 c,txt7,v1 d,txt8,v2   I want to print the 1st and 3rd column values where the the 1st column value is identical and the 3rd column value has changed from v1 to v2. So my expected output should be:  a   The second query is for the 3rd column values that has changed from v2 to v1. So my expected outcome:  b Let $a,b,c $ are non-negative real numbers, and $a+b+c=3$.  How to prove inequality $$ ab^2+bc^2+ca^2\le 4.\tag{*} $$    In other words, if $a,b,c$ are non-negative real numbers, then how to prove inequality $$ 27(ab^2+bc^2+ca^2)\le 4(a+b+c)^3.\tag {**} $$ $\color{gray}{\mbox{(Without using "universal" Lagrange multipliers method).}}$  Thanks! Proof of inequality using AM-GM inequality prove that $x^2 + y^2 + z^2 \ge xy + xz + yz$  I tried proving it the way I prove $x^2 + y^2 \ge 2xy$. But it just doesn't seem to work. I tried using AM-GM. Should I be using GM-HM or AM-HM? I really don't know what the problem is and I'd appreciate any help and a full proof explanation. Thanks. How to evaluate the integral $\int \sqrt{1+\sin(x)} dx$ To find:  $$\int \sqrt{1+\sin(x)} dx$$  What I  tried:  I put $\tan(\frac{x}{2}) = t$, using which I got it to:  $$I = 2\int \dfrac{1+t}{(1+t^2)^{\frac{3}{2}}}dt$$  Now I am badly stuck. There seems no way to approach this one. Please give a hint. Also, can we initially to some manipulations on the original integral to make it easy? Thank you. I am using XeLaTeX and memoir to write a longer text with several parts, chapters and sections. When printing the \tableofcontents I get a spacing problem with 2-figure numbers almost overlapping the relevant section name, as per enclosed picture.  I am aware that the memoir manual has a section dedicated to this theme, but the most part of it is doubledutch to me. Is there any easy way to avoid this problem? I'm basically searching for the opposite of putting all your eggs in one basket, where the risk is total failure because you did not hedge your efforts. I'm searching for a phrase that encompasses splitting your efforts and evokes the prospect of failing at both. A bird in the hand is worth two in the bush also encompasses a sense of having focused your efforts, but only alludes to total failure. To satisfy the criteria, the phrase must cover:  attempting two things (or multiple iterations of one thing) both of which you might succeed at, if you addressed them serially but both of which you fail at because you address them in parallel  Here are the idioms/phrases that do not sufficiently cover the idea and why:  &quot;A servant to two masters&quot;  This has the sense of competing priorities, but not the sense of failing to achieve your goals.  &quot;Jack of all trades. Master of none.&quot;  The sense is insufficiently pejorative. Being a jack-of-all-trades can be seen as an advantage; I'm trying to focus on the lack of mastery.  &quot;The man who fancied himself a wit, and was half-right.&quot;  From Christopher Hitchens. Hilarious, but lacking the sense of split effort between two things.  &quot;Walking and chewing gum at the same time.&quot;  An idiom for multi-tasking, not for failing to multi-task. Edit Addressing a few suggestions and another one that occurred to me:  &quot;Hedging your bets&quot; or &quot;Betting against yourself&quot;  In this case, you cannot win both bets, but you will almost certainly win one. You limit your upside, but also limit your risk. I'm looking in particular for total, catastrophic failure due to split attention/effort.  &quot;Can't walk and chew gum at the same time&quot;  Failing to do two fairly simple things that most everyone can do, not failing at two hard things because you tried to do both.  &quot;Robbing Peter to pay Paul&quot;  In this case, Paul gets paid. If you were to rob Peter to pay Paul, and get robbed yourself before you could get the money to Paul, that'd be closer. :)  &quot;Spreading yourself too thin&quot;  An actual English idiom, but missing the implied sense of failure.  &quot;Too many irons in the fire&quot;  &quot;A lot of irons in the fire&quot; can be viewed positively, so this is missing the sense of a strategic misstep.  &quot;Between a rock and a hard place&quot;  The sense is of needing to act but having no good alternative.  &quot;Falling between two stools&quot;  My favorite answer so far because it does appear to be an actual English idiom (not a proverb). In that sense, it's great, but some of the usages are closer to a failure of  than a failure of effort. And falling between two stools implies that the attempted action was simply sitting down.  &quot;Chasing two rabbits and catching none.&quot;  This is the exact sense I was looking for, but it appears to be a cross-cultural proverb rather than idiomatic English like &quot;putting all your eggs in one basket&quot;. I'll be accepting it, and using it in my work! But if there are other ideas, please let me know.

What can I use to find duplicate photos, including photos that have been resized? Hello native English speakers!  I want to ask you about either and both. I tried to find similar questions in this site but I think they were not same with these ones.  My questions are;   I was invited to two parties, but I couldn't go to ------- of them.  I took two books with me on holidays, but I didn't read ------- of     them.   I choose both for questions 1 and 2. But the right answers were either. But I think both and either are correct either. Am I right?   Thank you in advance! Where did Harry's parents get all of their money from? So, at the beginning of Harry Potter, Harry is found to have a large vault of gold at Gringotts.
