  • PHP: Profiling code and strict environment ~ Improving my coding

    - by DavidYell
    I would like to update my local working environment to be stricter in an effort to improve my code. I know that my code is okay, but as with most things there is always room for improvement. I use XAMPP on my local machine, for simplicities sake Apache Friends XAMPP (Basic Package) version 1.7.2 So I've updated my php.ini : error_reporting to be E_ALL | E_STRICT to help with the code standard. I've also enabled the XDebug extension zend_extension = "C:\xampp\php\ext\php_xdebug.dll" which seems to be working, having tested some broken code and got the nice standard orange error notice. However, having read this question, http://stackoverflow.com/questions/133686/what-is-the-best-way-to-profile-php-code and enabled the profiler, I cannot seem to create a cachegrind file. Many of the guides that I've looked at seem to think you need to install XDebug in XAMPP which leads me to think they are out of date, as XDebug is bundled with XAMPP these days. So I would appreciate it if anyone can help point me in the right direction with both configuring XDebug to output grind files, and or just a great set of default settings for the XDebug config in XAMPP. Seems there is very little documentation to go on. If people have tips on integrating these tools with Netbeans, that would be awesomesauce. I'm happy to get suggestions on other things that I can do to help tighten up my php code, both syntactically and performance wise Thanks, and apologies for the rambling question(s)! Ninja edit I should menion that I'm using named vhosts as my Apache configuration, which I think is why running XDebug on port 9000 isn't working for me. I guess I'd need to edit my vhost to include port 9000

  • Coding the Python way

    - by Aaron Moodie
    I've just spent the last half semester at Uni learning python. I've really enjoyed it, and was hoping for a few tips on how to write more 'pythonic' code. This is the __init__ class from a recent assignment I did. At the time I wrote it, I was trying to work out how I could re-write this using lambdas, or in a neater, more efficient way, but ran out of time. def __init__(self, dir): def _read_files(_, dir, files): for file in files: if file == "classes.txt": class_list = readtable(dir+"/"+file) for item in class_list: Enrol.class_info_dict[item[0]] = item[1:] if item[1] in Enrol.classes_dict: Enrol.classes_dict[item[1]].append(item[0]) else: Enrol.classes_dict[item[1]] = [item[0]] elif file == "subjects.txt": subject_list = readtable(dir+"/"+file) for item in subject_list: Enrol.subjects_dict[item[0]] = item[1] elif file == "venues.txt": venue_list = readtable(dir+"/"+file) for item in venue_list: Enrol.venues_dict[item[0]] = item[1:] elif file.endswith('.roll'): roll_list = readlines(dir+"/"+file) file = os.path.splitext(file)[0] Enrol.class_roll_dict[file] = roll_list for item in roll_list: if item in Enrol.enrolled_dict: Enrol.enrolled_dict[item].append(file) else: Enrol.enrolled_dict[item] = [file] try: os.path.walk(dir, _read_files, None) except: print "There was a problem reading the directory" As you can see, it's a little bulky. If anyone has the time or inclination, I'd really appreciate a few tips on some python best-practices. Thanks.

  • Learning a new language coding 1 program

    - by Steve
    This is not really a programming question Question : Sometimes you have to learn a new language consider this situation for example : you have been programming in C# for some years and then one day you need to code in java. Now being a programmer you already know the programming concepts its just the syntax you need to get used to. Can you think some program to code which covers every(or most) aspect of a programming language? like say you make a desktop search program...it can cover file reading writing, threads maybe interacting with db like sqllite so you get familiar with those topics and the syntax of the new language Just want to know your thoughts about what is the fastest way to go about learning a new language skipping all the basic stuff

  • Newbie PHP coding problem: header function (maybe, I need someone to check my code)

    - by Haskella
    Hi, consider the following PHP code: <?php $searchsport = $_REQUEST['sport']; $sportarray = array( "Football" => "Fb01", "Cricket" => "ck32", "Tennis" => "Tn43", ); header("Location: ".$sportarray[$searchsport].".html"); //directs user to the corresponding page they searched if ($searchsport == NULL) { header("Location: youtypednothing.html"); //directs user to a page I've set up to warn them if they've entered nothing } else { header("Location: sportdoesnotexist.html"); //if sport isn't in my root, a warning will appear } ?> I think the code comments are self-explanatory, basically when I type Tennis on my form.html it will send data to this php file and process and direct me to Tn43.html which is my tennis page. Unfortunately, it doesn't work and I really want to know why... (I know I've made some huge silly mistake). PS: Is header the right function to use when doing some redirecting?

  • PHP coding a price comparaison tool

    - by Tristan
    Hello, it's the first time I developp such tool you all know (the possibility to compare articles according to price and/or options) Since I never did that i want to tell me what do you think of the way i see that : On the database we would have : offer / price / option 1 / option 2 / option 3 / IDseller / IDoffer best buy / 15$ / full FTP / web hosting / php.ini / 10 / 1 .../..../.... And the request made by the client : "SELECT * FROM offers WHERE price <= 20 AND option1 = fullFTP"; I don't know if it seems OK to you. Plus i was wondering, how to avoid multiples entries for the same seller. Imagine you have multiple offers with a price <= 20 with the option FullFTP for the same seller, i don't want him to be shown 5 times on the comparator. If you have any advices ;) Thanks

  • Good coding style to do case-select in XSLT

    - by Scud
    I want to have a page display A,B,C,D depending on the return value from XML value (1,2,3,4). My approaches are by javascript or XSLT:choose. I want to know which way is better, and why?

  • Using a "take-home" coding component in interview process

    - by Jeff Sargent
    In recent interviews I have been asking candidates to code through some questions on the whiteboard. I don't feel I'm getting a clear enough picture of the candidates technical ability with this approach. Granted, the questions might not be good enough, maybe the interview needs to be longer, etc, but I'm wondering if a different approach would be better. What I'd like to try is to create a simple, working project in Visual Studio and have it checked into source control. The candidate can check that code out from home/wherever and then check back in work representing their response to the assignment that I'll provide. I'm thinking that if the window of time is short enough and the assignment clear enough then the solution will be safe enough from all-out Googling (i.e. they couldn't search for and find the entire solution online). I would then be able to review the candidates work. Has enough worked with something like this before, either to vet a candidate or as a candidate yourself? Any thoughts in general? P.S. my first StackOverflow question - hi guys and gals. EDIT: I've seen comments about asking someone to work for free - I wouldn't mind paying the person for their time.

  • Windows desktop gadget RSS Feed colour coding items

    - by padjo
    I have a desktop gadget that pulls RSS Feeds from a website. The Feed contains information about issues - ie. Priority, Time, Description. The Feed items are displayed on the desktop - however I need to colour code them according to their priority ie 1 = red etc. using the substr function - is there a better way to do this using JavaScript / HTML? At the moment I've hacked together this - but is there a more elegant solution? if (feed.item.description.substr(10,1) == "1") { document.write "<a href colour="red"" + item + ">"; else if (feed.item.description.substr(10,1) == "2") { document.write "<a href colour="yellow"" + item + ">"; else { document.write "<a href colour="green"" + item + ">";

  • VB.NET Syntax Coding

    - by Yiu Korochko
    I know many people ask how some of these are done, but I do not understand the context in which to use the answers, so... I'm building a code editor for a subversion of Python language, and I found a very decent way of highlighting keywords in the RichTextBox through this: bluwords.Add(KEYWORDS GO HERE) If scriptt.Text.Length > 0 Then Dim selectStart2 As Integer = scriptt.SelectionStart scriptt.Select(0, scriptt.Text.Length) scriptt.SelectionColor = Color.Black scriptt.DeselectAll() For Each oneWord As String In bluwords Dim pos As Integer = 0 Do While scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) >= 0 pos = scriptt.Text.ToUpper.IndexOf(oneWord.ToUpper, pos) scriptt.Select(pos, oneWord.Length) scriptt.SelectionColor = Color.Blue pos += 1 Loop Next scriptt.SelectionStart = selectStart2 End If (scriptt is the richtextbox) But when any decent amount of code is typed (or loaded via OpenFileDialog) chunks of the code go missing, the syntax selection falls apart, and it just plain ruins it. I'm looking for a more efficient way of doing this, maybe something more like visual studio itself...because there is NO NEED to highlight all text, set it black, then redo all of the syntaxing, and the text begins to over-right if you go back to insert characters between text. Also, in this version of Python, hash (#) is used for comments on comment only lines and double hash (##) is used for comments on the same line. Now I saw that someone had asked about this exact thing, and the working answer to select to the end of the line was something like: ^\'[^\r\n]+$|''[^\r\n]+$ which I cannot seem to get into practice. I also wanted to select text between quotes and turn it turquoise, such as between the first quotation mark and the second, the text is turquoise, and the same between the 3rd and 4th etcetera... Any help is appreciated!

  • Python program to search for specific strings in hash values (coding help)

    - by Diego
    Trying to write a code that searches hash values for specific string's (input by user) and returns the hash if searchquery is present in that line. Doing this to kind of just learn python a bit more, but it could be a real world application used by an HR department to search a .csv resume database for specific words in each resume. I'd like this program to look through a .csv file that has three entries per line (id#;applicant name;resume text) I set it up so that it creates a hash, then created a string for the resume text hash entry, and am trying to use the .find() function to return the entire hash for each instance. What i'd like is if the word "gpa" is used as a search query and it is found in s['resumetext'] for three applicants(rows in .csv file), it prints the id, name, and resume for every row that has it.(All three applicants) As it is right now, my program prints the first row in the .csv file(print resume['id'], resume['name'], resume['resumetext']) no matter what the searchquery is, whether it's in the resumetext or not. lastly, are there better ways to doing this, by searching word documents, pdf's and .txt files in a folder for specific words using python (i've just started reading about the re module and am wondering if this may be the route, rather than putting everything in a .csv file.) def find_details(id2find): resumes_f=open("resume_data.csv") for each_line in resumes_f: s={} (s['id'], s['name'], s['resumetext']) = each_line.split(";") resumetext = str(s['resumetext']) if resumetext.find(id2find): return(s) else: print "No data matches your search query. Please try again" searchquery = raw_input("please enter your search term") resume = find_details(searchquery) if resume: print resume['id'], resume['name'], resume['resumetext']
