• Can I float a block of text like an image?

  - by george.entenman.name

  If you change "float:right" to "float:left" in this W3schools example, you'll get an image floating to the left of the paragraph. I want to do the same thing with a block of text. The purpose is to be able to have little annotations to the left of paragraphs. If you know of any way to do this, I'd be very grateful. I'd be really grateful (and amazed) if there were a way to place this annotation midway in a paragraph and have text flow around it. I've searched all over for an answer but possibly don't know how to ask the question so that search engines can help me. So now I'm appealing to humans!!

• Get all sets of list in prolog

  - by garm0nboz1a

  How can I generate all the possible sets of the elements of a list with current length? get_set(X, [1,2,3]). X = [1,1,1], X = [1,1,2], X = [1,1,3], X = [1,2,1], X = [1,2,2], X = [1,2,3], X = [1,3,1], X = [1,3,2], X = [1,3,3], ..... X = [3,3,2], X = [3,3,3]. UPD: there is good answer given by Sharky. But maybe it's not the best. Here is another: get_set(X,L) :- get_set(X,L,L). get_set([],_). get_set([X|Xs],[_|T],L) :- member(X,L), get_set(Xs,T,L).

• Missing the Rails gem. Please `gem install -v=2.3.4 rails`

  - by Brian Roisentul

  I was trying to fix this error and I ended up with a new one. I have installed ruby 1.8.6, but using Built-in JRuby 1.4.0 for my app. Everything was working fine until I updated every gem(as specified by the answer I got from that link) and everything crashed: ever since I tried to start the app I received the following error message: Missing the Rails 2.3.4 gem. Please gem install -v=2.3.4 rails, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed. Then, I tried to uninstall the updates(to v2.3.8, most of them), so the last version is 2.3.4. In my config/environment.rb file I have this: RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION so I guess everything is as I left it before the update. The question is....why do I keep getting the error and I can't start the app?

• Private vs. Public members in practice (how important is encapsulation?)

  - by Asmor

  One of the biggest advantages of object-oriented programming is encapsulation, and one of the "truths" we've (or, at least, I've) been taught is that members should always be made private and made available via accessor and mutator methods, thus ensuring the ability to verify and validate the changes. I'm curious, though, how important this really is in practice. In particular, if you've got a more complicated member (such as a collection), it can be very tempting to just make it public rather than make a bunch of methods to get the collection's keys, add/remove items from the collection, etc. Do you follow the rule in general? Does your answer change depending on whether it's code written for yourself vs. to be used by others? Are there more subtle reasons I'm missing for this obfuscation?

• External files (css, js) in embedded jetty

  - by user1938185

  With jetty, you can easily produce "html" response importing external file like : <head> <link rel="stylesheet" type="text/css" href="myStyle.css"> <script src="myScript.js"></script> <head> However, where do you put myStyle.css and myScript.js, when jetty is embedded? Especially when the jetty server is a large OpenSource project not written by you? Is there by any chance a nice out.println(???); in the servlet.doGet that would provide the answer, or something similar?

• Is it possible to use a String as a seed for an instance Random? [duplicate]

  - by danpetruk

  This question already has an answer here: Converting String to long in Java 5 answers I have a String value and I would like to init a random class using the string as a seed? Is it possible to do this, and if so how? UPDATE 1: The string consists not only of ASCII. I can have any utf-8 symbols. UPDATE 2: Why did you close it? The questions really aren't about the same. Firstly because I've utf8 string and secondary because different strings can produce same seeds

• Use of Shl in assembly

  - by user3097712

  I have the following piece of lines and I do not understand that. Hope that someone can help me: ..... MOV EAX, DWORD PTR SS:[EBP-0x4] SHL EAX, 0x2 ADD EAX, DWORD PTR SS:[EBP-0x8] PUSH EAX .... Normally, it helps me to translate that into C language. But somehow I cant find a way to do it in that case. So, I only know that in the second line with SHL the register is multiplied by 4. And that the DWORD PTR SS:[EBP-0x4] looks like an array representation but i am not sure. I also find the following link x86 Assembler: shl and other instructions But I dont understand the answer there. So my question would be: What it is going on there? Thx...

• how to use javascript to download a file on Chrome without Chrome auto renaming file to "download"? [duplicate]

  - by user3688566

  This question already has an answer here: Is there any way to specify a suggested filename when using data: URI? 11 answers I use javascript to generate a file and download. It seems that depending on the version of chrome, the download file names can be auto renamed to 'download'. is there a way to avoid it? this is my code: var link = document.createElement("a"); link.setAttribute("href", 'data:application/octet-stream,' + 'file content here'); link.setAttribute("download", 'file1.txt'); link.click(); This is not a duplicated question because i am using the latest chrome and the previously suggested hyperlink is exactly what i am using. I think chrome v34 works fine. but once my chrome autoupdated to v35, it went back to 'download' file name.

• jquery this and other elements

  - by odavy

  OK, going rond in circles again - I'm sure the answer will be obvious. Just not to me :) I can't seem to specify this as one target amongst a few targets for a function: $(this, "elem1, elem2").doStuff() I just want to doStuff() to a pair of elements, one of which is this. I can only get it to work if I explicitly name the elements, ie... $("elem1, elem2, elem3").doStuff() ...works fine. But I can't seem to get it to work if I want to include this in the list. I have to write one line just for this, and another for elem1 elem2 etc. All help greatly appreciated. Thanks.

• Can we overload a function based on only whether a parameter is a value or a reference?

  - by skydoor

  I got the answer NO! Because passing by value and passing by reference looks identical to the caller. However, the code below compiles right class A { public: void f(int i) {} void f(int& i) {} }; But when I try to use it, there is compile error. int main () { A a; int i = 9; int& j = i; a.f(1); a.f(i); a.f(j); return 0; } Why does not the compiler disable it even without knowing it is going to be used?

• New datatype which can have numbers upto 100 digits.

  - by ckv

  Note: This was an interview question and may not have an actual use case currently The question was to design a class that can store numbers which are very very large say each number can have 100 digits. This new class is a datatype like int. What are the different types of constructors, overloads and other functions that you would write. How can this be further extended to support really large floating point numbers. How this can be given to others so that they can reuse the same component with their own additional functionality. My answer consisted of 2 approaches 1. using array of integers to store every say 10 digits 2. using string itself to store the number and perform operations on individual numbers. What would be the best approach?

• PHP and Javascript cookies

  - by shummel7845

  Can I access a cookie written with jQuery's cookie plug-in with PHP? I know you can't set Javascript equal to PHP or vice versa, but IN ESSENCE is: $.cookie('var') = $_COOKIE['var']? Again, I know you can't set them equal to each other, but if I set it in jQuery and then go to another page, can PHP access it? I've read lots of posts about this, but I can't seem to find an answer to this part. Note, if I look in Firefox's preferences, I can see the cookies are there, so I know they're set.

• Apache not handling files correctly (Handler Help)

  - by ethanschaefer

  I'm trying to set up my .htaccess file correctly and I'm having an issue. The only thing my .htaccess file at the moment is: AddType application/x-httpd-php .php .html .htm This is included because my server is not parsing php in my html files. However when this is included in my .htaccess file, when I open a page in my browser, the user is prompted to save or open the file locally. I believe the answer to my issues is setting up an action to be done (run with php) however I cannot find out the path to my php files. Any help is appreciated.

• grep --include command doesn't work in OSX zsh

  - by icemelon

  I am following the best answer on Finding all files containing a text string in linux to search string in my project. This is my command grep --include=*.rb -rnw . -e "pattern" Zsh tells me that zsh: no matches found: --include=*.rb It seems that grep doesn't support --include option. When I type grep --help, it returns usage: grep [-abcDEFGHhIiJLlmnOoPqRSsUVvwxZ] [-A num] [-B num] [-C[num]] [-e pattern] [-f file] [--binary-files=value] [--color=when] [--context[=num]] [--directories=action] [--label] [--line-buffered] [--null] [pattern] [file ...] no --include here. Is my grep version too old? Or is there something wrong with my command?

• What does the & sign mean in PHP?

  - by jeffkee

  I was trying to find this answer on Google but I guess the symbol & works as some operator, or is just not generally a searchable term for any reason.. anyhow. I saw this code snippet while learning how to create wordpress plugins, so I just need to know what the & means when it precedes a variable that holds a class object. //Actions and Filters if (isset($dl_pluginSeries)) { //Actions add_action('wp_head', array(&$dl_pluginSeries, 'addHeaderCode'), 1); //Filters add_filter('the_content', array(&$dl_pluginSeries, 'addContent')); }

• MySQL: Select remaining rows

  - by Bjork24

  I've searched everywhere for this, but I can't seem to find a solution. Perhaps I'm using the wrong terms. Either way, I'm turning to good ol' trusty S.O. to help my find the answer. I have two tables, we'll call them 'tools' and 'installs' tools = id, name, version installs = id, tool_id, user_id The 'tools' table records available tools, which are then installed by a user and recorded in the 'installs' table. Selecting the installed tools are simple enough: SELECT tools.name FROM tools LEFT JOIN installs ON tools.id = installs.tool_id WHERE user_id = 99 ; How do I select the remaining tools -- the ones that have yet to be installed by user #99? I'm sorry if this is painfully obvious, but I just can't seem to figure it out! Thanks for the help!

• What will or won't cause a thread to block (a question from a test)

  - by fingerprint211b

  I've had a test, and there was a question I lost some points on, because I wasn't able to answer it : Which of the following is NOT a condition which can cause a thread to block : Calling an objects's wait() method Waiting for an I/O operation Calling sleep() Calling yield() Calling join() As far as I know, all of these are blocking calls : wait() returns when an something calls notify(), blocks until then If the thread is WAITING for an I/O operation then it's obviously blocked sleep(), obviously, blocks until the time runs out, or something wakes up the thread yield() "cancels the rest of the thread's timeslice" (lacking a better term), and returns only when the thread is active again join() blocks until the thread it's waiting for terminates. Am I missing something here?

• Why does `Array.length`, `Function.length`, `String.length`, etc return 1?

  - by zealoushacker

  While teaching my JavaScript class yesterday, my students and I came across some interesting functionality that I thought might be worth capturing in a question and the answer I've come to. Typing Array.length in the JS console in chrome returns 1. Likewise, Function.length returns 1. This is important because: Every function in JavaScript is actually a Function object. (MDN JS Ref: Function) Thus, Object.length and likely all other native objects will and should return 1 as the value of the length property. So, finally why is this behavior occurring?

• Downloading Spring Framework 3.2.x

  - by PM 77-1

  I'm looking at springsource community download site. It shows that 3.2.4 is the latest general release. Its zip file has dist suffix and the content is different than the latest in 3.1 branch 3.1.4 (which does not have dist ending). 3.1.4 has the following directories: dist projects src dist folder contains org.springframework...* jars. 3.2.4 has the following directories: docs libs schema lib folder contains spring-... jars Was there a major change between 3.1 and 3.2 releases? According to this accepted answer there was but I was not able to find anything about it. Does anybody have any particulars? Should I get 3.1.4 for now?
