7,465,792 | 0 | <p>Regular expressions are like the <code>sort</code> function in Perl. You think it's pretty simple because it's just a single command, but in the end, it uses a lot of processing power to do the job.</p> <p>There are certain things you can do to help out:</p> <ol> <li>Keep your syntax simple as possible.</li> <li>Precompile your regular expression pattern by using qr// if you're using that regular expression in a loop. That'll prevent Perl from having to <em>compile</em> your regular expression with each loop.</li> <li>Try to avoid regular expression syntax that has to do <a href="http://perldoc.perl.org/perlre.html#Special-Backtracking-Control-Verbs" rel="nofollow">backtracking</a>. This usually ends up being the most general matching patterns (such as <code>.*</code>). </li> </ol> <p>The wretched truth is that after decades of writing in Perl, I've never masted the deep dark secrets of regular expression parsing. I've tried many times to understand it, but that usually means doing research on the Web, and ...well... I get distracted by all of the other stuff on the Web.</p> <p>And, it's not that difficult, any half decent developer with an IQ of 240, and a penchant for sadism should easily be able to pick it up. </p> <hr> <blockquote> <p>@David W.: I guess I'm confused on backtracking. I had to read your link several times but still don't quite understand how to implement it (or, not implement it) in my case. – user522962</p> </blockquote> <p>Let's take a simple example:</p> <pre><code>my $string = 'foobarfubar'; $string =~ /foo.*bar.*(.+)/; my $result = $1; </code></pre> <p>What will <code>$result</code> be? It will be <code>r</code>. You see how that works? Let's see what happens.</p> <p>Originally, the regular expression is broken into tokens, and the first token <code>foo.*</code> is used. That actually matches the whole string:</p> <pre><code>"foobarfubar" =~ /foo.*/ </code></pre> <p>However, if the first regular expression token captures the whole string, the rest of the regular expression fails. Therefore, the regular expression matching algorithm has to back track:</p> <pre><code>"foobarfubar" =~ /foo.*/ #/bar.*/ doesn't match "foobarfuba" =~ /foo.*/ #/bar.*/ doesn't match. "foobarfub" =~ /foo.*/ #/bar.*/ doesn't match. "foobarfu" =~ /foo.*/ #/bar.*/ doesn't match. "foobarf" =~ /foo.*/ #/bar.*/ doesn't match. "foobar" =~ /foo.*/ #/bar.*/ doesn't match. ... "foo" =~ /foo.*/ #Now /bar.*/ can match! </code></pre> <p>Now, the same happens for the rest of the string:</p> <pre><code>"foobarfubar" =~ /foo.*bar.*/ #But the final /.+/ doesn't match "foobarfuba" =~ /foo.*bar.*/ #And the final /.+/ can match the "r"! </code></pre> <p>Backtracking tends to happen with the <code>.*</code> and <code>.+</code> expression since they're so loose. I see you're using non-greedy matches which can help, but it can still be an issue if you are not careful -- especially if you have very long and complex regular expressions.</p> <p>I hope this helps explain backtracking.</p> <p>The issue you're running into isn't that your program doesn't work, but that it takes a long, long time.</p> <p>I was hoping that the general gist of my answer is that regular expression parsing isn't as simple as Perl makes it out to be. I can see the command <code>sort @foo;</code> in a program, but forget that if <code>@foo</code> contains a million or so entries, it might take a while. In theory, Perl could be using a bubble sort and thus the algorithm is a O<sup>2</sup>. I hope that Perl is actually using a more efficient algorithm and my actual time will be closer to O * log (O). However, all this is hidden by my simple one line statement.</p> <p>I don't know if backtracking is an issue in your case, but you're treating an entire webpage output as a single string to match against a regular expression which could result in a very long string. You attempt to match it against another regular expression which you do over and over again. Apparently, that is quite a process intensive step which is hidden by the fact it's a single Perl statement (much like <code>sort @foo</code> hides its complexity).</p> <p>Thinking about this on and off over the weekend, you really should not attempt to parse HTML or XML with regular expressions because it is so sloppy. You end up with something rather inefficient and fragile.</p> <p>In cases like this may be better off using something like <a href="http://search.cpan.org/~gaas/HTML-Parser-3.68/Parser.pm" rel="nofollow">HTML::Parser</a> or <a href="http://search.cpan.org/~grantm/XML-Simple-2.18/lib/XML/Simple.pm" rel="nofollow">XML::Simple</a> which I'm more familiar with, but doesn't necessarily work with poorly formatted HTML.</p> <p>Perl regular expressions are nice, but they can easily get out of our control.</p> |

I would like to see something close to serial communication, if possible.</p> <p>Also, when looking at the serial monitor, I get:</p> <pre><code>[...] 408295030 4238727231 3091191349 2815507344 ----------->(THEN SUDDENLY)<------------ HTTP/1.1 200 OK Date: Thu, 02 Jun 2 2900442411 016 19:29:41 GMT Server: Apache/2.4.17 (Win32) PHP/5.6.15 X-P16 3817418772 Keep-Alive: timeout=5 Connection: Keep-Alive Content-Type: te 86026031 HTTP/1.1 200 OK Date: Thu, 02 Jun 2016 19:29:4 3139838298 75272508 [...] ----------->(After 330 iterations/POSTs, I get)<------------ NO CARRIER NO CARRIER NO CARRIER NO CARRIER </code></pre> <p>So my question is: 1) How do I eliminate the 200 ms delay as well?</p> <p>2) If my data-points have different sizes, the delay will have to change as well. How to do this dynamically?</p> <p>3) Why does it stop at 330-ish iterations? This doesn't happen if data is only 4 digits.</p> <p>4) Why do I suddenly get responses from the server?</p> <p>I hope someone can use this for their own project, however this does not suffice for mine. Any ideas?</p> |

14,797,735 | 0 | Memcache - How to prevent frequent cache rebuilds? <p>I have been working for Memcache for the last week or so, I have managed to work out how to set keys/delete keys. This is fine but Im still attempting to work out how to do the same for a while loop of results. </p> <p>For example I will have a while loop of posts, from within the logic the function will check to see if Memcache is set, if not it will collect the results and create the key. My question is this, <strong>If I have set the looped data into a set key and display the set key (Newest First) Then what happens when a new post is inserted?</strong> I understand I can set a time limit on the set key, but as the content will/could be added whenever it seems that setting a limit could still display old posts. So my question is how would I be able to update the set key. </p> <p>The only way I can think of a possible solution is for when a user inserts a new post, this deletes the key, and when the all posts is viewed again this is when the key gets set again. But this seems rather counter productive, just as if there are 10's of users submitting posts then all the posts will be set over and over again (Doesn't really seem beneficial)</p> <p>I hope this makes sense, any help or guidance would be appreciated.</p> |

29,048,677 | 0 | <p>First of all, I will assume that this is homework and you must not use <code>std::string</code>. If you can use <code>std::string</code>, forget about everything and refrain from using dynamically allocated C-style strings!</p> <hr> <p>Here we go. If you want to replace <em>one</em> character (a space) with <em>two</em> characters (two stars), then your output string becomes <strong>larger</strong>.</p> <pre><code>"hello there, world!" = 19 characters "hello**there,**world!" = 21 characters </code></pre> <p>I doubt that overwriting the character following each space with a star conforms to the requirements of this exercise:</p> <pre><code>"hello**here,**orld!" = 19 characters, but seems to be wrong </code></pre> <p>You have space for 49 characters, but what if you enter, say, a string with 45 non-spaces and 5 spaces? The result would consist of 55 characters. More generally speaking: <strong>Who says the resulting string will fit in the old array?</strong></p> <p>The easiest way to overcome this problem and arrive at a satisfactory solution is to first <em>count</em> the number of spaces, then <em>allocate a new string</em>, then <em>copy</em> the characters.</p> <p>Here is an example. I left your original way of receiving user input, and a few other problems with the code, intact, even though it could use a few further improvements. This is <em>not</em> C++ code you would use in production! I also used <code>malloc</code> and <code>free</code> to conform to the general C-style of your code (in fact, this may really be a C exercise!). Take it strictly as a learning exercise:</p> <pre><code>#include<iostream> #include<cstdio> #include<cstring> #include<cstdlib> using namespace std; int new_size(char str[]); char* convert(char str[], int new_size); int main() { char string[50]; cout<<"Enter a string "<<endl; gets(string); int new_size_with_stars = new_size(string); char* new_string = convert(string, new_size_with_stars); printf("result: %s\n", new_string); free(new_string); return 0; } int new_size(char str[]) { int result = 0; for (int i = 0; str[i] != '\0'; ++i) { if (str[i] == ' ') { ++result; } ++result; } return result; } char* convert(char str[], int new_size) { char* new_str = (char*) malloc(new_size + 1); for(int old_str_index = 0, new_str_index = 0; str[old_str_index] != '\0'; ++old_str_index, ++new_str_index) { if (str[old_str_index]==' ') { new_str[new_str_index] = '*'; new_str[new_str_index + 1] = '*'; ++new_str_index; } else { new_str[new_str_index] = str[old_str_index]; } } new_str[new_size] = '\0'; return new_str; } </code></pre> |

I agree with most posts on this question in that it does depend on the needs of the application, but what also must be considered are the needs of the backend, meaning those who might actually have to use the data later on. As Vincent stated, if you plan on doing reporting, or somehow using the data that you're storing for some purpose later on, then generally you'll want to be sure you avoid making it harder on yourself or whomever may be using the data. If all you're worried about is storing it, then do whatever makes you happy.</p> |
