As a result, there could be all sorts of lurking security issues with users accessing files they shouldn't be able to; while these are generally fixed they're not considered "priority" as they would be with a production server, and no one's really banging on it looking for these things. </p> <p>Furthermore, see this summer's <a href="http://www.djangoproject.com/weblog/2009/jul/28/security/" rel="nofollow noreferrer">Django security update</a> that fixed a situation where a maliciously-crafted URL could give a visitor access to any file the Django user could see, even if it wasn't under the static root. It's fixed, but should give you an idea about why you should use a Real Server in production settings.</p> |

8,482,144 | 0 | <p>Like the other answers above, i agree that this is just asking for an injection attack (and probably other types). Some things that you can do to prevent that and enhance security in other ways could be the following:</p> <p>1 Look for something suspicious with your response handler. Lack of a query variable in the post, for instance, doesn't make sense, so it should just kill the process.</p> <pre><code>@$_POST["query"] or die('Restricted access'); </code></pre> <p>2 Use preg_match to sanatize specific fields.</p> <pre><code>if (!preg_match("/^[a-zA-Z0-9]+$/", $_POST[query])){ die('Restricted access'); } </code></pre> <p>3 Use more fields, even if they are semi-meaningless and hidden, to add more reasons to kill the process through their absence, or lack of a certain text pattern (optional).</p> <p>4 You shouldn't send a complete query through the POST at all. Just the elements that are necessary as input from the user. This will let you build the query in PHP and have more control of what actually makes it to the final query. Also the user doesn't need to know your table names</p> <p>5 Use mysql_real_escape_string on the posted data to turn command characters into literal characters before entering data into a db. This way someone would have a last name of DROP TABLE whatever, instead of actually dropping table whatever.</p> <pre><code>$firstname = mysql_real_escape_string($_POST[fname]); $lastname = mysql_real_escape_string($_POST[lname]); $email = mysql_real_escape_string($_POST[email]); $sql="INSERT INTO someTable (firstname, lastname, email) VALUES('$firstname','$lastname','$email')"; </code></pre> <p>6 Last, but not least, be creative, and find more reasons to kill your application, while at the same time giving the same die message on every die statement (once debugging is done). This way if someone is hacking you, you don't give them any feedback that they are getting through some of your obstacles.</p> <p>There's always room for more security, but this should help a little.</p> |

19,266,185 | 0 | <p>This involves some guesswork - does <code>admin</code> relate just to <code>quant1</code>? and <code>admin_custom</code> to just <code>quant1_cust</code>? Then this should reduce the effort required for a distinct list of those 2 fields:</p> <pre><code>SELECT `Fund_ID`, `Fund_Name` FROM `admin` INNER JOIN `quant1` ON `admin`.`Fund_ID` = `quant1`.`Fund_ID` AND `quant1`.`VaR 95`>-0.028 UNION SELECT `Fund_ID`, `Fund_Name` FROM `admin_custom` INNER JOIN `quant1_cust` ON `admin_custom`.`Fund_ID` = `quant1_cust`.`Fund_ID` AND `admin_custom`.`user_id` = `quant1_cust`.`user_id` AND `quant1_cust`.`VaR 95`>-0.028 WHERE `admin_custom`.`user_id`=361 ; </code></pre> <p>Looking at your existing query structure there are several things I would suggest you do not do. There is no point in using UNION and SELECT DISTINCT. Don't use select * with UNION or UNION ALL - be specific and only involve the fields you really need. And your existing where clause does suppress any nulls returned by a left join - so don't use left join.</p> <pre><code>SELECT DISTINCT --<< effort for distinctiveness here ... FROM ( SELECT * --<< too many fields ... UNION --<< effort for distinctiveness here SELECT * --<< too many fields ... ) LEFT JOIN ( SELECT * --<< too many fields ... UNION --<< effort for distinctiveness here SELECT * --<< too many fields ... ) quant1 WHERE quant1 ... </code></pre> <p>edit: an alternate - sorry, it might be easier to follow this way:</p> <pre><code>SELECT `Fund_ID`, `Fund_Name` FROM `admin` INNER JOIN `quant1` ON `admin`.`Fund_ID` = `quant1`.`Fund_ID` WHERE `quant1`.`VaR 95`>-0.028 UNION SELECT `Fund_ID`, `Fund_Name` FROM `admin_custom` INNER JOIN `quant1_cust` ON `admin_custom`.`Fund_ID` = `quant1_cust`.`Fund_ID` AND `admin_custom`.`user_id` = `quant1_cust`.`user_id` WHERE `admin_custom`.`user_id`=361 AND `quant1_cust`.`VaR 95`>-0.028 ; </code></pre> |

33,168,568 | 0 | Prevent element width from shrinking <p>I have a tooltip with some text, and in order to control the tooltip's position relative to the cursor with CSS, I placed it inside a zero-sized div. Javascript moves the outer div, and the tooltip can be aligned via any of the top/right/left/bottom attributes, depending on which side it should be placed on.</p> <p>However, this creates a new problem - the tooltip contents now tries to use as little width as possible. I can't disable wordwrap because it needs to fit on mobile screens. Without the outer container, it works perfectly, stretching up to the window edge. Is there a way to ignore the outer container while calculating the line breaks?</p> <p>From what I can tell, the tooltip no longer 'sees' the body element so it can't know how much it can stretch. However, controlling the tooltip position directly via Javascript is more complicated if I need to align the bottom or right sides - I have to either consider tooltip size (which can change depending on its position), or set bottom/right properties and consider window size.</p> <p>Here's an example: <a href="http://jsfiddle.net/03gdomLt/1/" rel="nofollow">http://jsfiddle.net/03gdomLt/1/</a><br> The first tooltip works correctly, while the second one tries to shrink to zero width.</p> <pre><code>.tip-outer { position: absolute; top: 200px; left: 100px; } .tooltip { position: absolute; left: 10px; top: 10px; border: 1px solid black; } <div class="tip-outer"> <div class="tooltip"> Lorem ipsum dolor sit amet, consectetur adipiscing elit.

21,287,685 | 0 | <blockquote> <p>Is node traversal far better (in a multilevel datetime index) in term of performance than dealing with indexed properties for dates in this case?</p> </blockquote> <p>No, indexed properties for dates is more performant than traversals for this type of data structure.</p> <p>Here is detailed example of using a hybrid approach. Consider the following subgraph, where the elipses indicate a continuing pattern in the graph.</p> <p><img src="https://i.stack.imgur.com/896SD.png" alt="Multilevel Calendar Index"></p> <p>Please take a look at <a href="https://gist.github.com/kbastani/8519557" rel="nofollow noreferrer">https://gist.github.com/kbastani/8519557</a> for the full calendar Cypher scripts that get or create (merge) a multilevel datetime index. This data structure allows you to traverse from one date to another date to get a range of events for a time series. A combination of both indexed property matching and traversals is the best approach, and is performant when modeled correctly.</p> <p><img src="https://i.stack.imgur.com/Pc1iB.png" alt="Example Data Model for Time"></p> <p>For example, consider the following Cypher query:</p> <pre><code>// What staff have been on the floor for 80 minutes or more on a specific day? WITH { day: 18, month: 1, year: 2014 } as dayMap // The dayMap field acts as a parameter for this script MATCH (day:Day { day: dayMap.day, month: dayMap.month, year: dayMap.year }), (day)-[:FIRST|NEXT*]->(hours:Hour), (hours)<-[:BEGINS]-(shift:Event), (shift)<-[:WORKED]-(employee:Employee) WITH shift, employee ORDER BY shift.timestamp DESC WITH employee, head(collect(shift)) as shift MATCH (shift)<-[:CONTINUE*]-(shifts) WITH employee.firstname as first_name, employee.lastname as last_name, SUM(shift.interval) as time_on_floor // Only return results for staff on the floor more than 80 minutes WHERE time_on_floor >= 80 RETURN first_name, last_name, time_on_floor </code></pre> <p>In this query we are asking the database "What staff have been on the floor for 80 continuous minutes or more on a specific day?" where shifts are broken up into 20 minute continuous intervals pointing to the next one in the series as CONTINUE or BREAK. </p> <p>First you start with matching the day using the indexed properties. Then you scan the day's hours for connected events by traversing the datetime multilevel index. Then reverse the order of the events to get the most recent event in the series. Then traverse until a "BREAK" relationship is encountered. Finally, apply the condition of time_on_floor being greater or equal to 80 minutes.</p> |

Modifying the data? That's changing the list, which is contradictory to your original intentions.

When using a default magento install (sample data) the problem is not occurring, which means it’s isolated to the extension I’m using.</p> <p>I have had a dig about in the theme files and have isolated the currency functions to be occurring in the the files found in the following path (theme files)</p> <p>app\code\local\ <em>extension vendor</em> \ <em>extension name</em></p> <p>Within this folder there are various files which may be pertaining to currency inluding:</p> <p>CartController.php</p> <p>Order.php</p> <p>Price.php</p> <p>Total.php</p> <p>I am almost certain that it’s going to be a line of code within one of these files, or those within the specified folder that’s causing the issue. I am hoping someone is able to tell me where this final conversion is happening and in what file. There are equivalents of these files in the core magento folder and having this theme installed tells the website to use the third-party variants of the core/default magento file. If someone knows which file it is, I can post the code for that file to have a look at or perhaps if I knew which file I could debug myself.</p> <p>Thanks again!</p> |

I want to have the following:</p> <p>The user can check the RadioButtons. When the user clicks the Button, the JavaScript function should return all the checked radio buttons (I only need to know which RadioButton is checked). Since I know the name of the RadioButtons in my Windows 8 App, I can do the following:</p> <pre><code>var object = WebView.InvokeScript("JavaScriptFunctionNAME", NameOfRadiobutton); </code></pre> <p>So the WebView invokes the script and should get as a return the VALUE of the RadioButton, which is checked. </p> <p>“JavaScriptFunctionNAME” = name of the function in Javascript</p> <p>NameOfRadiobutton = the name of the RadioButton as a parameter (for example “frage1”).</p> <p>Currently I’m returning the value of the radiobutton, which is checked in the RadioGroup “frage1”. How can I check every RadioButton by it’s parameter? By this I mean I have a parameter “frage1” and return the value of the checked RadioButton. After this, I call the function again with the parameter “frage2” and return the checked RadioButtons value. Could anyone help me out with the JavaScript-function?</p> |

13,629,575 | 0 | How to use SSH with PuTTY using a proxy server? <p>This is a journey that doesn't seem to have an end. Please bear with the story.</p> <p>I am wanting to write a variety of Perl programs that connect to an SSH server. The server is a Mac, the client is Windows behind an HTTP proxy. PuTTY works perfectly to connect, but executing the Perl scripts isn't ideal, for several reasons.</p> <p>I want to have an interactive (not with the user, but with the software running on the server) Perl program running on the client and the server, a la how rsync works with the -e option.</p> <p>First step, how do I connect? I use plink (from PuTTY), which has a variety of useful options... tunneling, running a series of commands, etc. From there, I can easily run commands and scripts on the server and get back the result, process the result, and then do the next command. But this is SLOW because it has to renegotiate the PuTTY/SSH connection each time. Hence the desire for an interactive approach.</p> <p>When running plink in this manner, I could interact with the plink command, but I'm having trouble with double-piping (input and output, never mind triple-piping to also get STDERR). I tried everything on <a href="http://docstore.mik.ua/orelly/perl2/prog/ch16_03.htm" rel="nofollow">http://docstore.mik.ua/orelly/perl2/prog/ch16_03.htm</a> and nothing worked. Got various errors, etc.</p> <p>Next I tried writing my own client/server programs using sockets. Worked pretty well, except for some reason each time I run the SocketServer on the server program and then connect to it (using plink to tunnel localhost to the server's port), the port closes itself off and refuses future connections. So I have to change the port every time, which seems counterproductive (probably an issue with my code, but I don't see it).</p> <p>The next step was trying Expect.pm. However, that seems to only work under Linux or CYGWIN, which I don't want to get too deep into. This needs to stay native Windows as much as possible.</p> <p>My latest is looking into Net::SSH::Perl and other SSH modules. I set up a port 22 tunnel with plink and then in CYGWIN I try:</p> <pre><code>ssh user@localhost </code></pre> <p>I enter my password and all is wonderful! Works like a champ!</p> <p>So then I try the following program (again, with the port 22 tunnel established)</p> <pre><code>use Net::SSH::Perl; my $ssh = Net::SSH::Perl->new('localhost'); $ssh->login('<user>','<pass>'); my($stdout, $stderr, $exit) = $ssh->cmd('ls -l'); while (<$stdout>) { print; } </code></pre> <p>(user and pass above are substituted for the real user and pass) I can see the plink tunnel opening the forwarded port, but the program returns</p> <pre><code>Permission denied at E:\Scripts\ExplorationScripts\NetSSHPerl.pl line 3 </code></pre> <p>So, this is where I am... I have many more SSH Perl modules to try, but I was wondering if anyone else had this situation. I see tons of people using PuTTY and SSH stuff, but none of them are going through a proxy (and thus NEED PuTTY). And I don't have the time or patience to mess with something like corkscrew, so please let's not go down that particular rabbit hole.</p> <p>I'm open for suggestions...</p> <p>Thanks.</p> <p>... continuing the journey... the new thing I've tried, and y'all will probably laugh at this bass-ackward solution... I tunneled port 23 through the Mac to a Windows machine on the same network running Telnet. Then, using Net::Telnet I am able to telnet to the Windows machine. Very awkward. I also wanted to be able to establish the tunnel and then kill it at the end of the program, so I added some oddball stuff. Check it out and PLEASE help me get a better solution to this.</p> <pre><code>use Net::Telnet; #establish tunnel open my $tunnel,"| plink -L 23:<local IP of windows machine>:23 <server> -pw <pass>"; sleep 7; #Now it's time to do the telnet boogie! my $t=new Net::Telnet ( Timeout=>10, Errmode=>'return',Prompt => '/>$/'); #$t->output_log('telnet.log'); $t->input_log('telneti.log'); $t->open("localhost"); $t->login('<user>','<pass>'); @lines = $t->cmd("dir /b"); print @lines; $t->close(); print $tunnel "exit\n"; close $tunnel; </code></pre> <p>The $tunnel thing is the weirdness. plink will establish a terminal session, so I opened a handle to it's STDIN via the pipe. The -L establishes the tunnel. When I'm done with the telnetting, I print "exit" to plink which exits the bash session. I also use the "sleep 7" to give it enough time to establish the session. Ugh! But it seems to work moderately well.</p> |

14,368,301 | 0 | <p>You should have a look at this great module, <a href="https://github.com/caolan/async">async</a> which simplifies async tasks like this. You can use queue, simple example:</p> <pre><code>N = # of simultaneous tasks var q = async.queue(function (task, callback) { somehttprequestfunction(task.url, function(){ callback(); } }, N); q.drain = function() { console.log('all items have been processed'); } for(var i = 0; i < 2000; i++){ q.push({url:"http://somewebsite.com/"+i+"/feed/"}); } </code></pre> <p>It will have a window of ongoing actions and the tasks room will be available for a future task if you only invoke the callback function. Difference is, your code now opens 2000 connections immidiately and obviously the failure rate is high. Limiting it to a reasonable value, 5,10,20 (depends on site and connection) will result in a better sucess rate. If a request fails, you can always try it again, or push the task to another async queue for another trial. The key point is to invoke callback() in queue function, so that a room will be available when it is done.</p> |

559,018 | 0 | <p>I'm not sure how you'd get the "shared" LineStrings from your shapes. Secondly, once you reduce a "subset" of the shape since your endpoints may move from the original and you will not be able to make them match up after reduction.</p> <p>The nutshell of what I would do is basically use boolean operations to play with the reduced shapes.</p> <p>First, do what you do, namely create a temporary table of reduced shapes (called <code>#ReducedShapes</code>). </p> <p>Then, I would create a second temp table and find the areas of overlap (using <code>STIntersection</code>) between all shapes. In this table, I would basically have columns <code>naam1</code>, <code>naam2</code> and <code>intsec</code>, the last one being of type shape. Something like (untested):</p> <pre><code>INSERT INTO #IntSecs(naam1, naam2, intsec) SELECT s1.naam, s2.naam, s1.naam.STIntersection(s2.naam) FROM #ReducedShapes s1, #ReducedShapes s2 WHERE s1.naam.STIntersection(s2.naam) IS NOT NULL </code></pre> <p>This gets you a list of where pairs of shapes overlap. In fact, you have two rows for each overlap. For example, if A and B overlap you'd have and . I would make a pass and delete one of the two for each occurence.</p> <p>Lastly, for each overlap, I would subtract (<code>STDifference</code>) the intersection <strong>from only one of the two</strong> regions in the pair from the <code>#ReducedShapes</code> table. Imagine you have two squares A and B, half-overlapping. The operation would involve A.STDifference(B) meaning you keep all of B and half of A. I would insert the modified shapes into a third table (say <code>#ModifiedShapes</code>).</p> <p>Two problems: a) as you can see from your "orange" and "blue" shapes, they did not reduce similarly, so you'll get one of two possible reductions depending on how you deal with who "wins". b) a more complicated form of the problem is that, depending on the complexity of the initial shapes, you may get overlap between three or more regions. You'll have to determine your own way to establish which one shape "wins" in that intersection, based on your particular needs. It's not clear if there are constraints. Could be as simple as arbitrarily picking a winner by ordering, or more complicated since accuracy is important. </p> <p>The above concept unfortunately does not address the issue of gaps. This one's a little more complicated and I am not 100% sure how to resolve it. But, if you create a third table that subtracts (<code>STDifference</code> again) all the modified shapes <code>#ModifiedShapes</code> from all the original shapes in <code>#Shapes</code> (testing for overlap before actually subtracting, of course), you'd be left with the remainder shapes in the gaps. You'd want to aggregate the adjoining shapes and assign a "winning color", possibly merging it back in with the related shape.</p> <p>This answer is long and I will leave it like this. I may be barking up the wrong tree. Based on your feedback/questions, I would add to the post.</p> |

38,884,806 | 0 | <p>The problem is in <a href="http://pythonhosted.org/pyparsing/" rel="nofollow">pyparsing</a>:</p> <blockquote> <p>The pyparsing module is an alternative approach to creating and executing simple grammars, vs. the traditional lex/yacc approach, or the use of regular expressions. With pyparsing, you don't need to learn a new syntax for defining grammars or matching expressions - the parsing module provides a library of classes that you use to construct the grammar directly in Python.</p> </blockquote> <p>In order to "construct the grammar directly in Python", pyparsing needs to read the source file (in this case a matplotlib source file) where the grammar is defined. In what would usually just be a bit of harmless extra work, pyparsing is reading not just the matplotlib source file but everything in the stack at the point the grammar is defined, all the way down to the source file where you have your <code>import matplotlib</code>. When it reaches your source file it chokes, because your file indeed is not in UTF-8; 0x96 is the Windows-1252 (and/or Latin-1) encoding for the en dash. This issue (reading too much of the stack) has <a href="https://sourceforge.net/p/pyparsing/code/415/" rel="nofollow">already been fixed</a> by <a href="http://stackoverflow.com/users/165216/paul-mcguire">the author of pyparsing</a> so the fix should be in the next <a href="https://pypi.python.org/pypi/pyparsing" rel="nofollow">release of pyparsing</a> (probably 2.1.8).</p> <p>By the way, matplotlib is defining a pyparsing grammar in order to be able to read fontconfig files, which are a way of configuring fonts used mainly on Linux. So on Windows pyparsing is probably not even required to use matplotlib!</p> |
40,839,068 | 0 | <blockquote> <p>This is really surprising to me, is there any internal memory copy that slow down the processing?</p> </blockquote> <p><code>ArrayOps.drop</code> internally calls <code>IterableLike.slice</code>, which allocates a builder that produces a new <code>Array</code> for each call:</p> <pre><code>override def slice(from: Int, until: Int): Repr = { val lo = math.max(from, 0) val hi = math.min(math.max(until, 0), length) val elems = math.max(hi - lo, 0) val b = newBuilder b.sizeHint(elems) var i = lo while (i < hi) { b += self(i) i += 1 } b.result() } </code></pre> <p>You're seeing the cost of the iteration + allocation. You didn't specify how many times this happens and what's the size of the collection, but if it's large this could be time consuming.</p> <p>One way of optimizing this is to generate a <code>List[String]</code> instead which simply iterates the collection and drops it's <code>head</code> element. Note this will occur an additional traversal of the <code>Array[T]</code> to create the list, so make sure to benchmark this to see you actually gain anything:</p> <pre><code>val items = s.split(" +").toList val afterDrop = items.drop(2).mkString(" ") </code></pre> <p>Another possibility is to enrich <code>Array[T]</code> to include your own version of <code>mkString</code> which manually populates a <code>StringBuilder</code>:</p> <pre><code>object RichOps { implicit class RichArray[T](val arr: Array[T]) extends AnyVal { def mkStringWithIndex(start: Int, end: Int, separator: String): String = { var idx = start val stringBuilder = new StringBuilder(end - start) while (idx < end) { stringBuilder.append(arr(idx)) if (idx != end - 1) { stringBuilder.append(separator) } idx += 1 } stringBuilder.toString() } } } </code></pre> <p>And now we have:</p> <pre><code>object Test { def main(args: Array[String]): Unit = { import RichOps._ val items = "hello everyone and welcome".split(" ") println(items.mkStringWithIndex(2, items.length, " ")) } </code></pre> <p>Yields:</p> <pre><code>and welcome </code></pre> |
