• PHP: image size help me out

  - by Karem

  Yes following from this: PHP: if more than ..px resize to.. As you can see it resizes if: if($width > 604 && $height > 453) { This works fine.. Although what if $width is over 604, and $height is under 453.. eg: 604x300, then this will skip the resize procedure..and same contrary(width is under, height is over). Also, if the dimensions on a picture is 500x900, and it gets resized, it gets really ugly resized. any great fix? Any good suggestion on how I should handle this please?

• Does C++ require a destructor call for each placement new?

  - by Josh Haberman

  I understand that placement new calls are usually matched with explicit calls to the destructor. My question is: if I have no need for a destructor (no code to put there, and no member variables that have destructors) can I safely skip the explicit destructor call? Here is my use case: I want to write C++ bindings for a C API. In the C API many objects are accessible only by pointer. Instead of creating a wrapper object that contains a single pointer (which is wasteful and semantically confusing). I want to use placement new to construct an object at the address of the C object. The C++ object will do nothing in its constructor or destructor, and its methods will do nothing but delegate to the C methods. The C++ object will contain no virtual methods. I have two parts to this question. Is there any reason why this idea will not work in practice on any production compiler? Does this technically violate the C++ language spec?

• To not iterate through function of Array object if it is added to Array prototype

  - by Rishat Muhametshin

  According to the way to add indexOf method to Array class in IE6, how do I now reject this method from iterating through any random array? For example: Array.prototype.indexOf = function(needle) { ... }; var array = [1, 2, 3]; for (var i in array) { document.write(i + ': ' + array[i]); } gives output 0: 1 1: 2 2: 3 indexOf: function ... How can I skip indexOf property and stop iterating on it without adding any code to where for(...) is called?

• How-to handle errors in Vim Script ?

  - by ereOn

  In my .vimrc file, I have the following function, which folds the licensing information on the top of some .hpp and .cpp files: " Skip license function! FoldLicense() if !exists("b:foldedLicense") let b:foldedLicense = 1 1;/\*\//fold endif endfunction au BufRead *.hpp call FoldLicense() au BufRead *.cpp call FoldLicense() This works well, but if I open a .cpp file which doesn't have any licensing information block, Vim complains that the pattern is not found. Fair enough, but is there a way so that he stops complaining and just does nothing if the pattern is not found ? Thanks !

• Forcing LINQ to SQL to make one single call for all child rows

  - by zaph0d

  Let say I have a method (example taken from another post): public IQueryable<CityBlock> GetCityBlocks(){ var results = from o in db.city_blocks let buildings = GetBuildingsOnBlock(o.block_id) //returns Iqueryable select new CityBlock { BuildingsOnBlock = buildings, BlockOwner = o.block_owner }; return results; } In the calling method I add Skip() and Take() methods plus some filtering and then do a ToList(). The trouble is that I am getting dozens of database calls - one for all the city blocks and then a separate one for each building. Is there a way that I can refactor this code to just make two calls: one for the city blocks and one for all the buildings

• how does this animation work?

  - by icicleking

  I'm working with cookies to run or not run a jQuery animation someone else built: $(function () { $('div.transitional').click(function () { $('div.intro').removeClass('hidden'); $('div.final').off('click'); }); ShowDiv($("div.transitional.hidden")[0]); }); function ShowDiv(target) { target = $(target); target.removeClass('hidden'); target.delay(500).animate({ opacity: 1.0 }, 300, 'easeInExpo', function () { ShowDiv($("div.transitional.hidden")[0]); }) } I have the cookie part working, but I'm confused about the anonymous function and the "ShowDiv" function. What is each part doing? Functionally, the animation makes visible a series of pictures, then the whole site. I want to skip the animation and just make the whole site visible(if cookies='visited'). I'd like to do this without rewriting the animation script. here's a link. What happens now is if you have the cookie the animation doesn't run and everything is hidden.

• StreamSocket to Stream in windows phone 8

  - by Abouzar Nouri

  I am trying to use Bluetooth in WP8 to send an image from my app on a device and show it in my app on another device. The receiver has a StreamSocket object to read the data from it like the code below await _dataReader.LoadAsync(4); uint messageLen = (uint)_dataReader.ReadInt32(); await _dataReader.LoadAsync(messageLen); string imageData _dataReader.ReadString(messageLen); Then I have to save all the received data (image) on the device and then create a Stream object from the stored data to give it to the BitmapSource.SetSource(Stream) function to be able to show this image on my app. var image = new BitmapImage(); image.SetSource(stream); All I want to do is not to skip this double work and directly convert the StreamSocket object (from Bluetooth connection) to a Stream object and make the BitmapSource image. Is there any way to do this?

• Pretty-print HTML via PHP without validation?

  - by brianjcohen

  I'd like to automatically pretty-print (indentation, mostly) the HTML output that my PHP scripts generate. I've been messing with Tidy, but have found that in its efforts to validate and clean my code, Tidy is changing way too much. I know Tidy's intentions are good but I'm really just looking for an HTML beautifier. Is there a simpler library out there that can run in PHP and just do the pretty-printing? Or, is there a way to configure Tidy to skip all the validation stuff and just beautify?

• Need help specifying a ending while condition

  - by johnthexiii

  I have written a Python script to download all of the xkcd comic images. The only problem is I can't tell it to stop when it gets to the last one... Here is what I have so far. import re, mechanize from urllib import urlretrieve from BeautifulSoup import BeautifulSoup as bs baseUrl = "http://xkcd.com/1/" #Specify the first comic page br = mechanize.Browser() #Create a browser response = br.open(baseUrl) #Create an initial response x = 1 #Assign an initial file name while (SomeCondition): soup = bs(response.get_data()) #Create an instance of bs that contains the response data img = soup.findAll('img')[1] #Get the online file path of the image localFile = "C:\\Comics\\xkcd\\" + str(x) + ".jpg" #Come up with a local file name urlretrieve(img["src"], localFile) #Download the image file response = br.follow_link(text = "Next >") #Store the response of the next button x += 1 #Increase x by 1 print "All xkcd comics downloaded" #Let the user know the images have been downloaded Initially what I had was something like while br.follow_link(text = "Next >") != br.follow_link(text = ">|"): but by doing this I actually send skip to the last page before the script has a chance to perform the intended purpose.

• how to call a php class function directly using ajax?

  - by payling

  Is it possible to call a php class function DIRECTLY using ajax? Something like below... except ajax... myclass::myfunction(); I've been using the jquery library to work with AJAX. $.get('control.php', {func: funcName, arg1: arg1}); The above is similar to what I'm trying to achieve MINUS the control.php; I'm not sure if this is even possible, but I just thought it would be nice to skip the landing page (control.php) that recieves the funcName. I have a bunch of conditional statements that sort out what class function to run based on the funcName recieved. It seems kind of silly to do this, to have a separate page just to handle function calls. Is there a better way?

• jQuery cookie behaves differently on local machine vs production server

  - by user1810414

  I'm setting a jQuery cookie for some site javascript effects. I'm setting expiration date to 30 days. On local development machine cookie expiration is set properly, whereas on production expiration is being set to end of session. After inspecting the created cookies with web develoer tools, everything is identical except production machine cookie is marked as "session cookie" and setting expiration is disallowed, while cookie created on local development machine is not set to "session" and expiration date is editable. Is there a way to make production machine cookie accept the expiration date? This is how I set the cookie: $.cookie('skip_animation','skip', 2592000); Using jQuery 1.6.4 (legacy site) All browsers behave the same way

• MySQL does not work on localhost without Local Area Connection

  - by user985171

  I use WampServer(Apache, PHP, MySQL) and have no problems when some kind of network adapter(wireless or lan) is connected(i-e Local Area Connection has status connected) 'even if i am not connected to the internet'(for example when i am connected to the router but that is not connected to the internet). When there is no network connection, i get a php error like MySQL could not connect to 127.0.0.1 on port 3306. Interestingly, 'telnet 127.0.0.1 3306' says that it could not connect to the port, even when the server and MySQL are running fine(i-e when some kind of local area connection is connected). So i turned off all kinds of firewall(antivirus and windows) but still no difference in anything. And that is why this issue is quite puzzling. Things i have already tried(will update this list along the way):- -The skip-networking directive in my.ini.

• When did people first start thinking 'C is portable assembler' ?

  - by Jacques Carette

  It seems to be an 'accepted concept' in the popular culture of programming languages that 'C is portable assembler'. I have first heard this at least 15 years ago. But when did it really become part of the popular culture? Note: if you don't agree that 'C is portable assembler', please just skip this question. This question is about 'popular culture of programming'. I'll add a comment to this question which you can up-vote for those who disagree with that statement.

• Has anyone properly interpreted HTTP request based on this demo of winpcap?

  - by httpinterpret

  The example is here, and I tried it by changing the filter to tcp and dst port 80 and the following: void packet_handler(u_char *param, const struct pcap_pkthdr *header, const u_char *pkt_data) { .... ip_len = (ih->ver_ihl & 0xf) * 4; tcp_len = (((u_char*)ih)[ip_len + 12] >> 4) * 4; tcpPayload = (u_char*)ih + ip_len + tcp_len; /* start of url - skip "GET " */ url = tcpPayload + 4; end_url = strchr((char*)url, ' '); url_length = end_url - url; final_url = (u_char*)malloc(url_length + 1); strncpy((char*)final_url, (char*)url, url_length); final_url[url_length] = '\0'; printf("%s\n", final_url); .... } But through debug, I see tcpPayload is full of messy code,not supposed "GET ..." stuff. What's wrong with my implement?

• Update existing columns and rows within csv file using Python

  - by wilbev

  So I've been attempting to use the csv module in Python to add data to existing rows and columns, but only specific columns of each row. So for examples let's say my existing csv file has the following: id, name, city, age 1, Ed,, 34 2, Pat,, 23 So basically the city of each person is missing, so I would like to update each row with that person's city. However, the writerow method only seems replace the existing data within the csv file. Changing the open file to append mode just adds the data to a new row. Is there any way to skip the existing data, and only add the city to each row? Thanks

• CodeIgniter | direct Echo during working script

  - by Sep O Sep

  Is it possible to echo something while the script for example is still running in a loop? my problem: I ask the server with Ajax and then the server is fetching mails and store them in Database. This took around 15 sec. During that Time the Server should echo his progress so that the Javascript can update a loading bar. This is working with a php script without CodeIgniter well. Is there a way to skip the output class and all that stuff to get a direct echo? Thanks

• Can pydoc/help() hide the documentation for inherited class methods and attributes?

  - by EOL

  When declaring a class that inherits from a specific class: class C(dict): added_attribute = 0 the documentation for class C lists all the methods of dict (either through help(C) or pydoc). Is there a way to hide the inherited methods from the automatically generated documentation (the documentation string can refer to the base class, for non-overwritten methods)? or is it impossible? This would be useful: pydoc lists the functions defined in a module after its classes. Thus, when the classes have a very long documentation, a lot of less than useful information is printed before the new functions provided by the module are presented, which makes the documentation harder to exploit (you have to skip all the documentation for the inherited methods until you reach something specific to the module being documented).

• Building ffmpeg with an executable output

  - by Kevin Galligan

  I generally don't like to ask such "you figure it out for me" questions, but I suspect this one will be really simple for a C++ guru. I want to build ffmpeg for Android, and I'd like it to output an executable rather than a set of libraries. We've been using the guardian project's build: https://github.com/guardianproject/android-ffmpeg It does produce what we want, but I've found tweaking it for different architectures to be, at best, unpleasant. I've gotten this version to build: https://github.com/appunite/AndroidFFmpeg It does a nice job of slicing and dicing different architectures, but produces a jni version. There is a long story as to why I want the exe, but I'll skip it for now. Is there a flag that needs to be flipped? Some path or other setting? I am at this point fully baffled. Thanks in advance.

• MATLAB: Designing a "Warm Start"

  - by squall14414

  I'm currently coding a function in MATLAB that has two steps: It processes some data It does some calculations on the processed data I'm using the function to run a series of experiments, where I tweak the way calculations occur in step 2). Seeing how I'm working with a large dataset and the data processing step takes a while each time, however, I'm wondering whether there is anyway to code in a "warm start" in the function. That is to say, is there anyway to save all the progress that I've done after step 1) so that if I run the function a second or third time, it can skip step 1) and go right to step 2)?

• JDBC Pagination

  - by Zeeshan

  Hi, I want to implement pagination using JDBC. The actual thing I want to know is "How can i get first 50 and then next 50 records from database for page 1 and 2 respectively" My Query is Select * from data [data table contains 20,000 rows] For page #1 I get 50 records and for page #2 I want to get next 50 records. How can I implement it efficiently in JDBC? I have searched and found that rs.absolute(row) is the way to skip first page records but it takes some amount of time on large result sets and I don't want to bear this amount of time. Also, I don't want to use rownum and limit + offset in query because these are not good to use in query, I dont know why, still I don't want to use it in query. Can anyone help me how to get limited ResultSet for pagination or is there any way JDBC is giving us?

• which one is a faster/better sql practice?

  - by artsince

  Suppose I have a 2 column table (id, flag) and id is sequential. I expect this table to contain a lot of records. I want to periodically select the first row not flagged and update it. Some of the records on the way may have already been flagged, so I want to skip them. Does it make more sense if I store the last id I flagged and use it in my select statement, like select * from mytable where id > my_last_id order by id asc limit 1 or simply get the first unflagged row, like: select * from mytable where flagged = 'F' order by id asc limit 1 Thank you!

• How to get line count from variable (from MYSQL query)?

  My problematic code: testMYSQL=`mysql -u $mysqlUser -p$mysqlPass -h $mysqlHost --skip-column-names --batch -D $mysqlDB -e "SELECT $select FROM $mysqlTable WHERE nameTXT='test';"` $testMYSQL now contains: test test test Then I do: TEST=$(echo $testMYSQL | wc -l) echo "$TEST" I would of thought that would work, but it doesn't, it returns 1 But if I put this into $testMYSQL: "test\ntest\ntest" it will say 3… Whats going on here? does MYSQL not use new lines? PS, I know I can use a for loop to loop though the lines then count up the lines that way, but I was hoping for a simpler solution like wc
