20,114,461 | 0 | adding a layer mask to UIToolBar/UINavigationBar/UITabBar breaks translucency <p>Im upgrading my UI to iOS 7, and have been using a custom tab bar which has a CAShapeLayer used as a mask. Ive been trying to add dynamic blur by having a UIToolBar underneath, but if i try setting the layer.mask property on the toolbar translucency is gone, and i just have it semi transparent (but masking works of course). Is there a way to get this working? Ive also seen this behavior when adding a subview to these classes.</p> |

16,121,678 | 0 | <p>In my case I had two models User and Admin and I am sticking with Devise, but I had a name collision issue with ActiveAdmin that requires me to remove the Admin model. But because there were so many references to Admin in devise, I had to take the steps below. I think it answers the original question above as well, though. I believe the correct way to do this is:</p> <p>1.Find the devise migration for the user model and roll it back <strong>[IMPORTANT: IF you DON'T want to remove the user table associated with Devise, then SKIP THIS STEP]</strong>:</p> <p><code>rake db:rollback VERSION=<insert the version number of the migration></code></p> <p>example: <code>rake db:rollback VERSION:20110430031806</code></p> <p>2.Run this command to remove Devise and associated files. <code>rails destroy devise Admin</code> (if Admin is the name of the model with user accounts).</p> <p>This produces this output:</p> <pre><code>invoke active_record remove db/migrate/20110430031806_devise_create_admins.rb remove app/models/admin.rb invoke test_unit remove test/unit/admin_test.rb remove test/fixtures/admins.yml route devise_for :admins </code></pre> <p>3.To completely remove Devise, you need to remove all references to it in your models, controllers and views. This is manual work. The answer above provides good details for finding this cruft, but was incomplete for my purposes. I hope this helps someone else.</p> |
7,515,056 | 0 | <p>thanks guys. i ended up setting the value of the option to <code>a</code> (my counter variable in the for loop). then i made the <code>var my_json</code> global. that way, in my onchange function for the select, i just do:</p> <pre><code>var passed_element_number = ($'#my_select_list').val(); var passed_id = my_json[passed_element_number].ID; var passed_otherfield = my_json[passed_element_number].OTHERFIELD; </code></pre> <p>i'm not sure why it wasn't letting me set the who json object as the value for the select option and then get the fields out 1 by 1 (probably my error, or maybe it's not possible), but this works ok....</p> |

33,362,325 | 0 | <p>There are different errors or mistakes in your code. I will go through them from top to bottom.</p> <ol> <li><p>Your variable <code>a</code> is never used. You could delete the whole <code>double a=sc.nextInt();</code> line without affecting your program</p></li> <li><p>Your variable <code>m</code> is not initialized and has no value when you use it the first time</p></li> <li><p>When calling a method you don't specify the data types. The data types will be taken from the variables you pass into that method. So there could be methods with the same name but with different data types in their parameter list. Imagine a method <code>int sum(int a, int b)</code> taking the parameters <code>a</code> and <code>b</code> that have to be of integer type. You can easily imagine, that there may be a situation where you don't want to sum integers but doubles. So you could look out for a method <code>double sum (double a, double b)</code> and you could use this method just like the first one but this time for variables/literals of double type. Like I wrote you don't write the data types of the parameters you pass into a method because they are determined automatically. So your <code>Math.pow(..)</code> call has to look like <code>power = Math.pow(m, n);</code></p></li> <li><p>Your code is lacking two <code>}</code> at the end (for the main method and for the class)</p></li> <li><p>Try to use self-describing names for your variables. A counter named <code>i</code> may be ok but you could easily rename <code>m</code> to <code>base</code> and <code>n</code> to <code>exponent</code> and your program would automatically be easier to read.</p></li> </ol> |

It's also important to have a <strong>spec/support/</strong> directory containing your configuration options for Jasmine. This directory should be created if you issue <strong>jasmine init</strong> from the root of your project.</p> <p><strong>spec/support/jasmine.json</strong> should look like the following for this example:</p> <pre><code>{ "spec_dir": "spec", "spec_files": [ "**/*[sS]pec.js" ], "helpers": [ "helpers/**/*.js" ] } </code></pre> <p>You should get JUnit XML output if you issue: <strong>jasmine spec/test_runner.js</strong> from the root of your project at a command line prompt.</p> <p>Lastly, to change the path to which your JUnit XML is written, you must change the <strong>savePath</strong> value in the object literal that is passed when creating a new instance of JUnitXmlReporter.</p> |

If not, how would you modify the EXIF script to also parse IPTC data?</p> <p><b>UPDATE</b></p> <p>I've modified the EXIF script I linked above. It <i>sorta</i> does what I want, but it's not grabbing the right data 100 percent of the time.</p> <p>After line 401, I added:</p> <pre><code>else if (iMarker == 237) { // 0xED = Application-specific 13 (Photoshop IPTC) if (bDebug) log("Found 0xFFED marker"); return readIPTCData(oFile, iOffset + 4, getShortAt(oFile, iOffset+2, true)-2); } </code></pre> <p>And then elsewhere in the script, I added this function:</p> <pre><code>function readIPTCData(oFile, iStart, iLength) { exif = new Array(); if (getStringAt(oFile, iStart, 9) != "Photoshop") { if (bDebug) log("Not valid Photoshop data! " + getStringAt(oFile, iStart, 9)); return false; } var output = ''; var count = 0; two = new Array(); for (i=0; i<iLength; i++) { if (getByteAt(oFile, iStart + i) == 2 && getByteAt(oFile, iStart + i + 1) == 120) { var caption = getString2At(oFile, iStart + i + 2, 800); } if (getByteAt(oFile, iStart + i) == 2 && getByteAt(oFile, iStart + i + 1) == 80) { var credit = getString2At(oFile, iStart + i + 2, 300); } } exif['ImageDescription'] = caption; exif['Artist'] = credit; return exif; } </code></pre> <p>So let me now modify my question slightly.

10,169,662 | 0 | <p>That package is a runtime package containing the VCL. You presumably also need to deploy rtl90.bpl for the RTL and possibly some others. By enabling runtime packages you are promising to deploy those packages where the executable can find them.</p> <p>You have 3 main options:</p> <ol> <li>Deploy the packages to a location that is contained in the PATH variable. Usually this means modifying PATH. You should never write to the system directory. It is owned by the system and you should respect that.</li> <li>Deploy the packages to the same directory as the executable file.</li> <li>Disable runtime packages and therefore build a single self-contained executable. The RTL/VCL code will be statically linked into your executable.</li> </ol> <p>Option 1 is poor in my view. Relying on the PATH variable and the ability to modify it is fragile. Option 2 works but seems rather pointless in comparison with option 3. You deploy more files and larger files when you choose 2, so why choose it.</p> <p>In summary I recommend option 3. Statically link all RTL/VCL code into your executable.</p> <p>The only situation where option 2 wins, in my view, is when you have multiple related executables that are all deployed to the same directory. In that situation sharing the RTL/VCL code can make sense.</p> |

2,038,097 | 0 | randomized binary search trees <p>Randomized binary search trees like treap give a good performance (in the order of O(log n)) with high probability while avoiding complicated (and costly) rebalancing operations that are needed for deterministic balanced trees like AVL, red-blackm, AA, etc.</p> <p>We know that if we add random keys to a simple BST, we can expect it is reasonably balanced. A simple reason is that the number of heavily non-balanced trees for n nodes it's much lower than the number of "almost balanced" trees and hence, a random order for the insertion of the keys is likely to end up with an acceptable tree.</p> <p>In this case, in "The Art of Computer Programming", Knuth gives a little bit more than 1.3*lg2(n) as the average length of a path which is rather good. He also says that <em>deleting</em> a random key from the a random tree preserves its randomness (and hence its good average balancing).</p> <p>It seems, then, that a binary search tree where keys are inserted and deleted in a random order would most likely give performance in the order of O(log n) for all three operations: search, insert and delete.</p> <p>That said, I wonder if the following approach would give the same good properties:</p> <ul> <li>take an hash function h(x) that is known to be "good" (e.g. it ensure an even spread of the keys)</li> <li>use the order set by h(x) on the keys instead of the ordering on k. </li> <li>in case of collision, order according the key. That should be rare if the hash key is good enough and the range of the hash function is much bigger than the set of the keys.</li> </ul> <p>To give an example a BST for the key { 4, 3, 5 , 1, 2} inserted in that order, would be:</p> <pre><code> 4 / \ 3 5 /\ 1 2 </code></pre> <p>Assuming the hash function would map them to (respectively) {221,142,12,380,18) we would get.</p> <pre><code> 221(4) / \ 142(3) 380(1) / \ 12(5) 18(2) </code></pre> <p>The key point is that a "regular" BST may degenerate because the keys are inserted according the same ordering relation that is used to store them in the tree (their "natural" ordering, for example the alphabetical order of string) but the hash function induces an ordering on the keys that is completely unrelated to the "natural" one and, hence, should give the same results as if the keys were inserted in random order.</p> <p>A strong assumption is that the hash function is "good", but it's not an unreasonable one, I think.</p> <p>I didn't find any reference to a similar approach in the literature so it might be completely wrong, but I can't see why!</p> <p>Do you see any drawback in my reasoning? Anyone has already attempted doing it?</p> |

What I need is try to match as much (or as little) as possible, disregarding delimiters.</p> <p>Basically for this input</p> <pre><code>int list[-45,54, 435 ,-65] </code></pre> <p>I'd like to be able to call and get this</p> <pre><code>s.nextWord() // int s.nextWord() // list s.nextSymbol() // [ s.nextInt() // -45 s.nextSymbol() // , s.nextInt() // 54 s.nextSymbol() // , s.nextInt() // 435 s.nextSymbol() // , s.nextInt() // -65 s.nextSymbol() // ] </code></pre> <p>and so on.</p> <p>Or, if it couldn't parse doubles and other types itself, at least a method that takes a regex, returns the biggest string that matches it (or an error) and sets the stream position to just after what it matched.</p> <p>Can the Scanner somehow be used for this? Or is there another approach? I feel this must be quite a common thing to do, but I don't seem to be able to find the right tool for it.</p> |

32,139,557 | 1 | Pandas for large(r) datasets <p>I have a rather complex database which I deliver in CSV format to my client.

16,816,114 | 0 | <p>Location Manager is not reliable on some phones. You may notice that if you launch google maps all of a sudden your app works. That is because Google Maps kicked the LocationManager. Which also means that there is programmatic way to kick that dude alive. So I used </p> <pre><code>HomeScreen.getLocationManager().requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 0, 0, new LocationListener() { @Override public void onStatusChanged(String provider, int status, Bundle extras) { } @Override public void onProviderEnabled(String provider) { } @Override public void onProviderDisabled(String provider) { } @Override public void onLocationChanged(final Location location) { } }); </code></pre> <p>After the above code, I called what ever I needed from LocationManager and it kinda worked. If not try out the new API's <code>LocationClient</code>. This is suppose to be much better, battery, accuracy and reliability.</p> |
25,610,938 | 0 | <p>The problem isn't that the plugin changes your structure (although it does add some <code>ins</code> elements, which I don't agree with), it's that the plugin doesn't fire a <code>change</code> event for the converted radio controls, and setting the <code>checked</code> property interactively doesn't appear to do so either.</p> <p>Since the plugin author doesn't publish an API for this use case, it's hard to know whether this is by design or oversight, but the source code definitely doesn't fire the event when the slider is clicked:</p> <pre><code>this.bearer.find('.slider-level').click( function(){ var radioId = $(this).attr('data-radio'); slider.bearer.find('#' + radioId).prop('checked', true); slider.setSlider(); }); </code></pre> <p>Your options, as I see them:</p> <ol> <li>Contact the API author and ask for a bug fix, or the intended way to support this case <ul> <li>Downside: Time: dependent on the author to respond</li> </ul></li> <li>Attach your "check" function to the <code>click</code> event of the <code>.slider-level</code> class, as the API does. <ul> <li>Downside: Brittle: future versions of the plugin may attach the behavior to different selectors</li> </ul></li> <li>Attach your function to the <code>click</code> event of your radio group, and catch click events on the bubble <ul> <li>Downside: Inefficient: It will check for every click in the radio control</li> </ul></li> </ol> <p>Here's a sample implementation of option 3. <strong><a href="http://jsbin.com/pisida/2/edit" rel="nofollow">DEMO</a></strong>.</p> <pre><code>$(document).ready(function () { $(".radios").radiosToSlider(); }); var makeIsRadioGroupChecked = function(selector) { var $radioGroup = $(selector); return function isRadioGroupChecked() { return $radioGroup.find(':checked').length > 0; }; }; var isOptionsChecked = makeIsRadioGroupChecked('#optionsRadioGroup'); var isSizeChecked = makeIsRadioGroupChecked('#sizeRadioGroup'); var areAllGroupsChecked = function() { return isOptionsChecked() && isSizeChecked(); }; var alertIfAllGroupsChecked = function() { if (areAllGroupsChecked()) { alert("all answered"); } }; $('.radios').on('click', alertIfAllGroupsChecked); </code></pre> |
