What to call a person who always says (as an example): I'm the strongest one. Says that he can do and do and whatever (But actually just boasting, whether he can or can't, but mostly ineffective)...
I am looking for idioms or informal/slang/colloquial expression for some people that make you think that they are able of building a skyscraper, constructing a spaceship, playing the piano better than Mozart or something very fancy that requires remarkable skills, but when it comes to practice they prove to be completely inadequate.
How can I obfuscate (protect) JavaScript? I want to make a JavaScript application that's not open source, and thus I wish to learn how to can obfuscate my JS code? Is this possible? When to switch to a CDN? How to fix very slow Ubuntu booting? GParted won't let me edit a partition Simple way of finding the locus of $z$? I am tasked to sketch the locus of complex numbers $z$ that satisfies $$(z-2+i)^2 + (z^*-2-i)^2 + 2zz^* + 6 = 0$$ I was wondering if there’s a special trick to this question, or if this is only solvable by plugging in $z=x+iy$ ? I noticed that the second term is the conjugate of the first, and wanted to substitute $w = z-2+i$, however this gives me a complicated expression for $zz^*$ which makes it more confusing. Is there a trick I’m missing out? Thanks! Edit: I have already solved it through direct substitution (parabola intersecting real axis at $x=3$ and $x=-1$) but it took a good 5 minutes or so, expanding everything correctly, which seems rather long (I was attempting it under exam conditions). I was just wondering if it is possible to exploit the $w$ substitution I made in particular. How do I run wireshark, with root-privileges? A standard installation of Wireshark doesn't give the program permission to access the network interface.   I suppose I have to run the program with sudo, but do not know how to add it to the icon - if that's the way to do it. Low output volume Translation of words according to babel language I've got a template that is to be used in french or english, is there a name in babel defining the "of" of "page x of yy" than I want to translate automaticaly to "page x sur y"  If not, is there a way of setting a name according to language selected in babel. Is the "omniscient-omnipotent-omnipresent" definition of God consistent? is commonly defined as an  (infinite knowledge),  (unlimited power),  (present everywhere) entity.  Is there any logical  in this definition?  I have seen several paradoxes like below     Does God know what he's going to do   tomorrow? If so, could he do something   else?" If God knows what will happen,   and does something else, he's not   omniscient. If he knows and can't   change it, he's not omnipotent.      "Can 'an omnipotent being' create a   stone so heavy that it cannot lift   it?"   Do they mean that the defintion of God ( as commonly held) is logically inconsistent? What do hollow/filled stars mean in chat? I was on chat in Stack Overflow and noticed that some of the message had grey stars with a black border while others were just black stars.

Is a rational-valued continuous function $f\colon[0,1]\to\mathbb{R}$ constant? Let $f\colon[0,1]\to\mathbb{R}$ be continuous such that $f(x)\in\mathbb{Q}$ for any $x\in[0,1]$. Intuitively I feel that $f$ is constant, since $\mathbb{Q}$ is dense in $\mathbb{R}$.  How can I formally write this down? Can two people with different one time pads securely exchange a message like this? Alice has a message, generates a one time pad, encrypts her message and sends it to Bob. Bob generates his own one time pad, encrypts the message again, and sends it back to Alice. Alice then decrypts this message using her one time pad, sends it back to Bob who then decrypts it the last time using his one time pad.  The only problems I see with this technique:   It is vulnerable to a man in the middle attack. It requires sending the message back and forth twice between sender and recipient. It doesn't scale well if you want to use it to communicate with multiple people. Requires a way of generating cryptographically secure random numbers.   Does this method of encryption have a name?  If we ignore the fact that it's vulnerable to a man in the middle attack, is this method of encryption information-theoretically secure?  Why isn't this method used widely, i.e. which of the above listed problems or other problems makes this method infeasible for production use? Does the MacBook battery cycle count reset when replacing a battery I've been  on battery cycle counts and checked out my current count on my MacBook (13-inch, Aluminum, Late 2008) - recommended maximum cycle count is 500.  I've had this laptop now for over 4 years and at the 2 year mark I had the battery replaced by AppleCare. The first time I checked out the cycle count was today and it's currently on 1004. Now my question is, is this the cycle count of the battery since I replaced it (as in, it reads the cycle count from the battery), or is it the combined cycle count (as in, it stores the count somewhere and increments occasionally)? My assumption is that it's the count of that battery but I have no idea how to verify this.  Either way, it looks like I need a new battery ;) The Problem  Accessing my site over https (the only protocol allowed) I get the content, but none of the CSS, images etc.  Drupal is creating pages in response to https requests that include http links to these resources, but it should be using https.  What I've done  I have copied a site to a dev server. The site loads and basically works fine - I can log in etc. It's just that all the links drupal generates are http. The site I've copied it from also runs over https. The site does not exist on http (it would just get a Forbidden error). I've drush cc all.  So Apache's working - I can access the site. .htaccess is working (clean urls work, for example).  I'm using SNI to access the site because the server has other vhosts too, but I'm only accessing the site using the latest Firefox (and as it's a dev site and I'm the only dev, nobody else will use it).  I've done this dozens of times and am quite stumped! Why does Drupal not notice that the request came over https?  The fix  Turns out that .htaccess has this to say:   /* Base URL (optional).                                                          If Drupal is generating incorrect URLs on your site, which could             be in HTML headers (links to CSS and JS files) or visible links on pages     (such as in menus), uncomment the Base URL statement below (remove the       leading hash sign) and fill in the absolute URL to your Drupal installation.    Sure enough, putting $base_url = 'https://example.com'; fixed it.  But why is this necessary? Aside from the Force, is there magic in Star Wars? Who can knight you so that the knighting 'sticks'? Motivating scenario:  I'm a swell upstanding guy, so Ser/Lord X, an acquaintance of mine, knights me. So I walk into my village tavern; the barkeep asks "What'll it be, friend?" and I tell him "That's 'Ser' to you now. I have been knighted by X!" He sneers and goes "well then, X can call you Ser if he likes."  Actual Question:  What about a person's being knighted makes the knighting 'stick'? Is it the identity/standing of the knighter (is that a word?) ? Is it the fact that many other knights walk around telling people that the new guy is also a Knight? Is it the public nature of the knighting?  The  says  about knighting:     This usually happens when a squire reaches adulthood and his master   judges him worthy of accepting the responsibilities of a knight. A man   who has not been raised in the knightly tradition can also be made a   knight as a reward for service. This is often granted to soldiers or   other smallfolk who have shown bravery or performed a great feat.   Notes:   I'm only asking about Westerosi Andal-culture Knights, around the time of Robert I Baratheon's rule. Car accident, put in park or neutral?
