• Invisible Delimiter for Strings in HTML

  - by noah

  I need a way to identify certain strings in HTML markup. I know what the strings are, but it is possible that they could be substrings of other strings in the document. To find them, I output a special delimiter character (currently using \032). On page load, we go through the HTML and record the location of the strings, and remove the delimiter. Unfortunately, most browsers show the delimiter character until we can find and remove them all. I'd like to avoid that if possible. Is there a character or string that will be preserved in the HTML content (so a comment wont work) but wont be visible to the user? It also needs to be something that is fairly unlikely to appear next to a string, so something like &nbsp; wouldn't work either. EDIT: Sorry, I forgot to mention that the strings will be in attributes, so any sort of tag wont work.

• PHP: xml_parse replaces entities and "?" character

  - by bhefny

  How can I describe something I can't quite put my finger on? I have a module for RSS reading "magpierss" it uses xml_parse() and after extensive troubleshooting all I can come up with is that it removes certain entities like "?" character. I haven't written this module myself but I have traced the code until the part uses xml_parse() and then the output is just replaced. And to my disappointment this behavior exists on our production server only and not the local server. I have compared both php.ini file to search for any differences but couldn't find anything. Could anyone please direct on where to search exactly, i don't even know which direction to start from. Thanks

• WinMain not called before main (C/C++ Program Entry Point Issue)

  - by BT

  I was under the impression that this code #include <windows.h> #include <stdio.h> int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) { printf("WinMain\n"); return 0; } int main() { printf("main\n"); return 0; } would output WinMain, but of course nothing ever works how you expects. Anyways, could somebody please tell me how to get this program to run WinMain first (I do have a reason for using both). I'm running windows 7 with mingw if that helps anything.

• javascript date.utc problem

  - by Dave

  I'm trying to compare 2 dates using javascript. 1 at the end of the month and 1 at the beginning. I need to compare these 2 dates in seconds so I'm using the Date.UTC javascript function. Here's the code: var d = Date.UTC(2010,5,31,23,59,59); document.write(d); var d2 = Date.UTC(2010,6,1,12,20,11); document.write(d2); The output for is: 1278028799000 1277986811000 This is telling me that 1/6/2010 is less than 5/31/2010 in milliseconds. How is that possible? What am I doing wrong? Thanks for your help.

• Python script run via cron does not execute occassionally

  - by gcorne

  I have a simple python script for fetching tweets and caching them to disk that is configured to run every two minutes via cron. */2 * * * * (date ; /usr/bin/python /path/get_tweets.py) >> /path/log/get_tweets.log 2>&1 The script runs successfully most of the time. However, every so often the script doesn't execute. In addition to other logging, I added a simple print statement above the meat of the script and nothing except the output from the initial date command makes it to the log. #!/usr/bin/python # Script for fetching tweets and then storing them as an HTML snippet for inclusion using SSI print "Starting get_tweets.py" Any ideas? The system is a VPS running Centos 5.3 with python 2.4.

• Razor support of generic extension methods

  - by Brian

  Hello, With regards to the Razor view engine, say I want to render Html.TextBoxFor<SomeModel>(i => i.Name), it doesn't seem that the inline syntax works as in: @Html.TextBoxFor<SomeModel>(i => i.Name) This doesn't seem to work because it interprets the generic as an HTML tag. I could use a code-block approach, but then what's the best approach to output the content? The HTML string returned from this method, do I response.write it, or is there a syntax for it, or what's the approach? Thanks.

• rails rollback updates when task fails

  - by ash34

  Hi, I have the following "generate_report" method being called from a rake task, which gets a hash as an input, that contains the reported hours spent by each user on a task and outputs the data as a .csv report. desc "Task reporting" task :report, [:inp_dt] => [:environment] do |t, args| h = select_data(args.inp_dt) /* not shown here */ generate_report(h) end def generate_report(h) out_dir = File.dirname(__FILE__) + '/../../output' myfile = "#{out_dir}" + "/monthly_#{Date.today.strftime("%m%d%Y")}.csv" writer = CSV.open(myfile, 'w') h.each do |h,v| v.each do |key,val| writer << val end end writer.close end where h = {:BILL=>{:PROJA=>["CYR", "00876", "2", 24], :PROJB=>["EPR", "00876", "2", 16]}, :JANE=>{:PROJA=>["TRB", "049576", "2", 16]}} I would like to set/update a 'processed' flag for each reported transaction and only commit the update when the file is written correctly or rollback the updates when the task fails. How can I accomplish this. thanks, ash

• nicely display file rename history in git log

  - by Jian

  The git command git log --format='%H' --follow -- foo.txt will give you the series of commits that touch foo.txt, following it across renames. I'm wondering if there's a git log command that will also print the corresponding historical file name beside each commit. It would be something like this, where we can interpret '%F' to be the (actually non-existent) placeholder for filename. git log --format='%H %F' --follow -- foo.txt I know this could be accomplished with git log --format='%H' --follow --numstat -- foo.txt but the output is not ideal since it requires some non-trivial parsing; each commit is strewn across multiple lines, and you'll still need to parse the file rename syntax ("bar.txt => foo.txt") to find what you're looking for.

• How to enable BDS2006's C++ WARN & TRACE macros.

  - by Psychic

  I am trying to find out how to enable (& use) Borland's WARN & TRACE macros. My starting point was this link: http://bcbjournal.org/articles/vol2/9809/Debugging_with_diagnostic_macros.htm?PHPSESSID=37bf58851bfeb5c199d1af31d7b2e7ff However, that appears to be for BCB5, and not the 2006 Borland Developer Studio. I've set the two defines (__WARN & __TRACE) I've included the .h file () I've added some macros, and everything compiles & links fine. But when I run the application (in DEBUG mode), no debug output file is created. What am I missing here?

  I am using the following script to decode a json. Although the var_dump($obj) returns result (similar to one in here Example #1), the echo line doesn't return any result, as if the $obj being null. <?php $clientJSONObject = file_get_contents('php://input'); $obj = json_decode($clientJSONObject, TRUE); var_dump($obj); // working. echo $obj; // returns nothing. echo $obj["carrier"]; // returns nothing. ?> var_dump output: array(2) { ["carrier"]=> string(8) "Etisalat" ["userLanguage"]=> string(2) "ar" }

• python - from matrix to dictionary in single line

  - by Sanich

  matrix is a list of lists. I've to return a dictionary of the form {i:(l1[i],l2[i],...,lm[i])} Where the key i is matched with a tuple the i'th elements from each list. Say matrix=[[1,2,3,4],[9,8,7,6],[4,8,2,6]] so the line: >>> dict([(i,tuple(matrix[k][i] for k in xrange(len(matrix)))) for i in xrange(len(matrix[0]))]) does the job pretty well and outputs: {0: (1, 9, 4), 1: (2, 8, 8), 2: (3, 7, 2), 3: (4, 6, 6)} but fails if the matrix is empty: matrix=[]. The output should be: {} How can i deal with this?

• jQuery, ajax request doesn't success with JSON on IE

  - by sylouuu

  I made an AJAX call and it works on FF & Chrome but not on IE 7-8-9. I'm loading a JSON file from my domain: $.ajax({ url: 'js/jquery.desobbcode.json', dataType: 'json', cache: false, success: function(json) { alert('ok'); }, error: function(xhr, errorString, exception) { alert("xhr.status="+xhr.status+" error="+errorString+" exception="+exception); } }); I also tried by adding contentType: 'application/json' but I receive the same output which is : xhr.status=200 error=parsererror exception=SyntaxError Unterminated string constant I checked my JSON file with JSONLint and it's OK. I checked if there is an extra comma and the content is also trimmed. See my JSON file If I put dataType: 'text', I receive the OK alert but a debug popup too. Could you help me? Regards.

• Powershell Select-Object from array not working

  - by Andrew

  I am trying to seperate values in an array so i can pass them to another function. Am using the select-Object function within a for loop to go through each line and separate the timestamp and value fields. However, it doesn't matter what i do the below code only displays the first select-object variable for each line. The second select-object command doesn't seem to work as my output is a blank line for each of the 6 rows. Any ideas on how to get both values $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data) $csv2 = convertFrom-CSV $csvdata $newarray = $csv2 | Where-Object {$_.utilization -ne "0.0000000000e+00" -and $_.utilization -ne "nan" } for ( $n = 0; $n -lt $newarray.Length; $n++) { $nTime = $newarray[$n] $nUtil = $newarray[$n] $util = $nUtil | select-object Utilization $util $tstamp = $nTime | select-object timestamp $tstamp }

• [CSS] style input tag

  - by nosferat

  Hi! ASP.Net has a tag called CheckboxList. The output of this tag looks like this: <table class="checkbox"> <tbody> <tr> <td> <input id="/*longdynamicstring1*/" type="checkbox" name="/*longdynamicstring2*/" /> <label for="/*longdynamicstring1*/">Label Text</label> </td> </tr> </tbody> </table> I want to position the label and the input but I cannot find out how. Tried the following: .checkbox input{ padding-right: 5px; } and .checkbox input[type='checkbox'] { padding-right: 5px; } but neither of them had any effect. Because it's ASP I cannot set a class for the input elements and I cannot reference the id because it's dynamic.

• Make Sphinx quiet (non-verbose)

  - by J. Pablo Fernández

  I'm using Sphinx through Thinking Sphinx in a Ruby on Rails project.

• DOM class injection in PHP

  - by Adam Kiss

  idea Via jQuery, I was able to mark all :first-child and :last-child elements in document (well, almost all :)) with class first which could I later style (i.e. first li in ul#navigation would be easily adressable as ul#navigation .first). I used following code: var $f = $('*:first-child') $f.addClass('first'); var $l = $('body *:last-child') $l.addClass('last'); question Now, my question is if it's possible to do the same via php, so non-JS users/gadgets could have the same effects and additional styling and also it would be less overkill on browser. So, is it possible to capture output, parse it as html and inject this class easily in php?

• Is there a faster method then StringBuilder for a max 9-10 step string concatenation?

  - by Pentium10

  I have this code to concate some array elements: StringBuilder sb = new StringBuilder(); private RatedMessage joinMessage(int step, boolean isresult) { sb.delete(0, sb.length()); for (int i = 0; i <= step; i++) { if (mStack[i] == null) continue; rm = mStack[i].getCurrentMsg(); if (rm == null || rm.msg.length() == 0) continue; if (sb.length() != 0) { sb.append(", "); } sb.append(rm.msg); } return sb.toString(); } Important the array holds max 10 items, so it's not quite much. My trace output tells me this method is called 18864 times, 16% of the runtime was spent in this method. Can I optimize more?

• Unable to install Ruby gems

  I am trying for the first time to install some Ruby gems on Mac OS X Leopard. Please see the command and the output below. My question is how do I install a gem with dependencies? I tried installing individual dependency gems first from a locally downloaded files but I soon found out that there is no end to the rabbit hole :-) I also found out that there are circular dependencies that break even this tedious method. There must be a better way! I would really appreciate your help. sudo gem install oauth Updating metadata for 1 gems from http://gems.rubyforge.org . complete ERROR: Error installing oauth: oauth requires actionpack (>= 2.2.0, < 2.3.0)

• How to increase query speed without using full-text search?

  - by andre matos

  This is my simple query; By searching selectnothing I'm sure I'll have no hits. SELECT nome_t FROM myTable WHERE nome_t ILIKE '%selectnothing%'; This is the EXPLAIN ANALYZE VERBOSE Seq Scan on myTable (cost=0.00..15259.04 rows=37 width=29) (actual time=2153.061..2153.061 rows=0 loops=1) Output: nome_t Filter: (nome_t ~~* '%selectnothing%'::text) Total runtime: 2153.116 ms myTable has around 350k rows and the table definition is something like: CREATE TABLE myTable ( nome_t text NOT NULL, ) I have an index on nome_t as stated below: CREATE INDEX idx_m_nome_t ON myTable USING btree (nome_t); Although this is clearly a good candidate for Fulltext search I would like to rule that option out for now. This query is meant to be run from a web application and currently it's taking around 2 seconds which is obviously too much; Is there anything I can do, like using other index methods, to improve the speed of this query?

• TYPO3: How do i render tt_content text elements in my own extensions?

  - by arturh

  I'm currently writing a TYPO3 extension which is configured with a list of tt_content UID's. These point to content elements of type "text" and i want to render them by my extension. Because of TYPO3s special way of transforming the text you enter in the rich text editing when it enters the database, and again transforming it when it is rendered to the frontend, i can not just output the database contents of the "bodytext" field. I want to render these texts as they would usually get rendered by TYPO3. How do I do that?

• To be a lazy developer or not to be a lazy developer?

  - by JamesStuddart

  Am I a lazy developer? Is it being lazy to use automated tools, such as code generators and such? Now, I could, if I had to, create all the data layers and entities I needed, but I choose to use CodeSmith to generate my datalayers and entities. I also use Resharper and I would say it fights with MSDeploy as to which gets installed first after Visual Studio. Again if I had to, I could code without it, but prefer not to. Both these tools from my point of view are no brainers as they improve output massively. But is this lazy? I'm sure there are purists out there that would say everything should be wirtten by you so you know what everything is doing, but if you can read through the code and see what is happening is that ok? So am I being lazy or am I just using all the cards in my hand?

• SSRS mysterious extra pages

  I have two reports that are setup with the same page dimensions- A4 portrait, with page margins of 1cm. When I run the reports seperately and print them they both come out as expected: fitting into the width constraint of the page. However, when I include one report as a subreport in the other and then run and print the "master" report I start to experience problems. Even though both reports appear I get extra blank pages appearing every other page in the output. I'm sure I'm missing a simple trick - probably with the page sizes of the two reports but I can't figure it out - any pointers? I don't mind changing the setup of the subreport as it will never be run as a seperate eport in the wild, I only included that step to prove that it did indeed fit within the page!
