16,860,338 | 0 | <p>I had a similar problem and the solution that I found was to replace the startActivityForResult functionality by storing the result into the shared preferences and loading them later in onResume.

18,134,031 | 0 | <p>Maybe you are confused by the fact, that the class <code>Ordering</code> is declared as <code>Ordering<T></code>, but the return value of the <code>onResultOf</code> method is <code>Ordering<F></code>.</p> <p>The first type argument of the <code>Function</code>, you are providing to <code>onResultOf</code> is the type argument of the result.</p> <p>That also means, that <code>Value</code> is not forced to be a subtype of <code>Map.Entry</code>.</p> |
19,243,491 | 0 | <p>I've been fighting with something like what you show (only one major tick in the axis range). None of the matplotlib tick formatter satisfied me, so I use <code>matplotlib.ticker.FuncFormatter</code> to achieve what I wanted. I haven't tested with twin axes, but my feeling is that it should work anyway.</p> <pre><code>import matplotlib.pyplot as plt from matplotlib import ticker import numpy as np #@Mark: thanks for the suggestion :D mi, ma, conv = 4, 8, 1./3. x = np.linspace(mi, ma, 20) y = 1 / (x ** 4) fig, ax = plt.subplots() ax.plot(x, y) # plot the lines ax.set_xscale('log') #convert to log ax.set_yscale('log') ax.set_xlim([0.2, 1.8]) #large enough, but should show only 1 tick def ticks_format(value, index): """ This function decompose value in base*10^{exp} and return a latex string. If 0<=value<99: return the value as it is. if 0.1<value<0: returns as it is rounded to the first decimal otherwise returns $base*10^{exp}$ I've designed the function to be use with values for which the decomposition returns integers """ exp = np.floor(np.log10(value)) base = value/10**exp if exp == 0 or exp == 1: return '${0:d}$'.format(int(value)) if exp == -1: return '${0:.1f}$'.format(value) else: return '${0:d}\\times10^{{{1:d}}}$'.format(int(base), int(exp)) # here specify which minor ticks per decate you want # likely all of them give you a too crowed axis subs = [1., 3., 6.] # set the minor locators ax.xaxis.set_minor_locator(ticker.LogLocator(subs=subs)) ax.yaxis.set_minor_locator(ticker.LogLocator(subs=subs)) # remove the tick labels for the major ticks: # if not done they will be printed with the custom ones (you don't want it) # plus you want to remove them to avoid font missmatch: the above function # returns latex string, and I don't know how matplotlib does exponents in labels ax.xaxis.set_major_formatter(ticker.NullFormatter()) ax.yaxis.set_major_formatter(ticker.NullFormatter()) # set the desired minor tick labels using the above function ax.xaxis.set_minor_formatter(ticker.FuncFormatter(ticks_format)) ax.yaxis.set_minor_formatter(ticker.FuncFormatter(ticks_format)) </code></pre> <p>The figure that I get is the following <img src="https://i.stack.imgur.com/HfNWP.png" alt="enter image description here">:</p> <p>Of course you can set different minor locators for x and y axis and you can wrap everything from <code>ticks_format</code> to the end into a function that accepts an axes instance <code>ax</code> and <code>subs</code> or <code>subsx</code> and <code>subsy</code> as input parameters.</p> <p>I hope that this helps you</p> |

13,207,244 | 0 | Programmatically adding UITextField to a dropdownlist <p>I have a tableview controlled by a UITableViewController.

18,390,045 | 0 | <p>You can do this using <code>hoist</code> from the <code>mmorph</code> package. <code>hoist</code> lets you modify the base monad of anything that implements <code>MFunctor</code> (which is most monad transformers):</p> <pre><code>hoist :: (MFunctor t) => (forall x . m x -> n x) -> t m r -> t n r </code></pre> <p>You can then use it for your problem like this:</p> <pre><code>co' tma ma = hoist (co ma) tma </code></pre> <p>Then you're done!</p> <p>To understand why that works, let's go through the types step by step:</p> <pre><code>co :: (Monad m) => m a -> m a -> m a ma :: (Monad m) => m a co ma :: (Monad m) => m a -> m a hoist (co ma) :: (Monad m, MFunctor t) => t m a -> t m a tma :: (Monad m, MFunctor t) => t m a hoist (co ma) tma :: (Monad m, MFunctor t) => t m a </code></pre> <p>Note that <code>hoist</code> has certain laws it must satisfy that ensure that it does "the right thing" that you would expect:</p> <pre><code>hoist id = id hoist (f . g) = hoist f . hoist g </code></pre> <p>These are just functor laws, guaranteeing that <code>hoist</code> behaves intuitively.</p> <p><code>hoist</code> is provided in the <code>Control.Monad.Morph</code> module of the <code>mmorph</code> package, which you can find <a href="http://hackage.haskell.org/package/mmorph" rel="nofollow">here</a>.

18,594,451 | 0 | ActiveDirectory DirectorySearcher: why is FindOne() slower than FindAll() and why are properties omitted? <p>I have a loop that retrieves some info from ActiveDirectory. It turned out to be a big performance bottleneck.</p> <p>This snippet (inside a loop that executed it 31 times) took 00:01:14.6562500 (1 minute and 14 seconds):</p> <pre><code>SearchResult data = searcher.FindOne(); System.Diagnostics.Trace.WriteLine(PropsDump(data)); </code></pre> <p>Replacing it with this snippet brought it down to 00:00:03.1093750 (3 secconds):</p> <pre><code>searcher.SizeLimit = 1; SearchResultCollection coll = searcher.FindAll(); foreach (SearchResult data in coll) { System.Diagnostics.Trace.WriteLine(PropsDump(data)); } </code></pre> <p>The results are exactly identical, the same properties are returned in the same order. I found some info on memory leaks in <a href="http://stackoverflow.com/questions/1135013/is-directorysearcher-sizelimit-1-for-findall-equal-to-findone-directoryse">another thread</a>, but they did not mention performance (I'm on .Net 3.5).</p> <hr> <p>The following is actually a different question but it gives some background on why I'm looping in the first place:</p> <p>I wanted to get all the properties in one single query, but I cannot get the DirectorySearcher to return all the wanted properties in one go (it omits about 30% of the properties specified in PropertiesToLoad (also tried setting it in the constructor wich makes no difference), I found someone else had the same problem and <a href="http://forums.asp.net/t/1822574.aspx/1" rel="nofollow">this is his solution (to loop through them)</a>. When I loop through them like this, either using FindOne() or FindAll() I do get all the properties, But actually it all feels like a workaround.</p> <p>Am I missing something?</p> <hr> <p>Edit:</p> <p>Seems like the problem was with the way I got the first DirectoryEntry on which I was using the DirectorySearcher.</p> <p>This was the code that caused the DirectorySearcher only to return some of the properties:</p> <pre><code>private static DirectoryEntry GetEntry() { DirectoryContext dc = new DirectoryContext(DirectoryContextType.DirectoryServer, "SERVERNAME", "USERNAME", "PASSWORD"); Forest forest = Forest.GetForest(dc); DirectorySearcher searcher = forest.GlobalCatalogs[0].GetDirectorySearcher(); searcher.Filter = "OU=MyUnit"; searcher.CacheResults = true; SearchResultCollection coll = searcher.FindAll(); foreach (SearchResult m in coll) { return m.GetDirectoryEntry(); } throw new Exception("DirectoryEntry not found"); } </code></pre> <p>After replacing that big mouthfull with just this line, the DirectorySearcher returned all the properties and looping was no longer needed:</p> <pre><code>private static DirectoryEntry GetEntry2() { return new DirectoryEntry(@"LDAP://SERVERNAME/OU=MyUnit,DC=SERVERNAME,DC=local", "USERNAME", "PASSWORD"); } </code></pre> <p>Now it takes less than one 18th of a second to get all wanted properties of 31 entries. So, it seems that two different instances of the same DirectoryEntry can give different results depending on the way it was constructed... feels a bit creepy!</p> <hr> <p>Edit</p> <p>Used <a href="http://www.jetbrains.com/decompiler/" rel="nofollow">JetBrains DotPeek</a> to look at the implementation. The FindOne function starts like this:</p> <pre><code>public SearchResult FindOne() { SearchResult searchResult1 = (SearchResult) null; SearchResultCollection all = this.FindAll(false); ... </code></pre> <p>My first reaction was Argh! no wonder... but then I noticed the argument. FindAll has a private version that accepts a boolean, this is the start of FindAll:</p> <pre><code>[TargetedPatchingOptOut("Performance critical to inline this type of method across NGen image boundaries")] public SearchResultCollection FindAll() { return this.FindAll(true); } private SearchResultCollection FindAll(bool findMoreThanOne) { ... // other code this.SetSearchPreferences(adsSearch, findMoreThanOne); </code></pre> <p>So this gives slightly more insight, but does not really explain much.</p> |

28,403,532 | 0 | <p>Your best bet is to provide a method to clean up the library. The end user will have to call it (presumably based on handling application lifecycle in the container). You could also provide a <code>Listener</code> for those cases when it is used in a compatible servlet container (e.g., Tomcat), but your end user will still have to be aware and put the descriptor in the web.xml.</p> <p>The only other alternative is that your end user is going to have to create a Listener that manages to get the thread to die. I have had to do this on several occasions and it is not pretty. It usually involves using reflection to get ahold of the thread and killing it. Of course, the ThreadDeath exception is handled by some libraries and the threads refuse to die. This then requires more significant use of reflection to clean up the mess.</p> <p>Your end users are much better off if you give them an easy way to clean up the library. It sucks that they have to know about your implementation details, but they already do because you are keeping the app from unloading.</p> |

40,215,971 | 0 | <p>There is no reason to choose between <code>putIfAbsent</code> and <code>computeIfPresent</code>. Most notably, <code>computeIfPresent</code> in entirely inappropriate as it, as its name suggests, only computes a new value, when there is already an old one, and <code>(k,v)->v</code> even makes this computation a no-op.</p> <p>There are several options</p> <ol> <li><p><code>containsKey</code>, <code>put</code> and <code>get</code>. This is the most popular pre-Java 8 one, though its the most inefficient of this list, as it incorporates up to three hash lookups for the same key</p> <pre><code>String key=str.substring(i, j); if(!map.containsKey(key)) map.put(key, new HashSet<>()); map.get(key).add(str); </code></pre></li> <li><p><code>get</code> and <code>put</code>. Better than the first one, though it still may incorporate two lookups. For ordinary <code>Map</code>s, this was the best choice before Java 8:</p> <pre><code>String key=str.substring(i, j); Set<String> set=map.get(key); if(set==null) map.put(key, set=new HashSet<>()); set.add(str); </code></pre></li> <li><p><code>putIfAbsent</code>. Before Java 8, this option was only available to <code>ConcurrentMap</code>s.</p> <pre><code>String key=str.substring(i, j); Set<String> set=new HashSet<>(), old=map.putIfAbsent(key, set); (old!=null? old: set).add(str); </code></pre> <p>This only bears one hash lookup, but needs the unconditional creation of a new <code>HashSet</code>, even if we don’t need it. Here, it might be worth to perform a <code>get</code> first to defer the creation, especially when using a <code>ConcurrentMap</code>, as the <code>get</code> can be performed lock-free and may make the subsequent more expensive <code>putIfAbsent</code> unnecessary.</p> <p>On the other hand, it must be emphasized, that this construct is not thread-safe, as the manipulation of the value <code>Set</code> is not guarded by anything.</p></li> <li><p><code>computeIfAbsent</code>. This Java 8 method allows the most concise and most efficient operation:</p> <pre><code>map.computeIfAbsent(str.substring(i, j), k -> new HashSet<>()).add(str); </code></pre> <p>This will only evaluate the function, if there is no old value, and unlike <code>putIfAbsent</code>, this method returns the new value, if there was no old value, in other words, it returns the right <code>Set</code> in either case, so we can directly <code>add</code> to it. Still, the <code>add</code> operation is performed outside the <code>Map</code> operation, so there’s no thread safety, even if the <code>Map</code> is thread safe. But for ordinary <code>Map</code>s, i.e. if thread safety is not a concern, this is the most efficient variant.</p></li> <li><p><code>compute</code>. This Java 8 method will always evaluate the function and can be used in two ways. The first one</p> <pre><code>map.compute(str.substring(i, j), (k,v) -> v==null? new HashSet<>(): v).add(str); </code></pre> <p>is just a more verbose variant of <code>computeIfAbsent</code>. The second</p> <pre><code>map.compute(str.substring(i, j), (k,v) -> { if(v==null) v=new HashSet<>(); v.add(str); return v; }); </code></pre> <p>will perform the <code>Set</code> update under the <code>Map</code>’s thread safety policy, so in case of <code>ConcurrentHashMap</code>, this will be a thread safe update, so using <code>compute</code> instead of <code>computeIfAbsent</code> has a valid use case when thread safety is a concern.</p></li> </ol> |

29,248,553 | 0 | <p>It sounds like you were trying to used nested loops, but you in fact had one loop at the beginning which closed out and then you loop through the rest. You need to move your closing curly brace marked below:</p> <pre><code>for($i=0; $i<count($_FILES['upload']['name']); $i++) { $filut = basename($_FILES['upload']['name'][$i]); } <<<<<<<<<=========== This curly brace closes the "for loop" if(isset($_POST['subi'])) { $data1 = $_POST['answers']; foreach($data1) as $postValues) { $sql4 = 'INSERT INTO db_image (text, image) VALUES("'.$postValues.'","'.$filut.'")'; $my->query($sql4); } } ??? <<<<<======== For a nested loop you should close it here </code></pre> <p>or perhaps you were trying to assign <code>$filut</code> as an array in which case the starting <code>for...</code> loop needs to look like this:</p> <pre><code>for($i=0; $i<count($_FILES['upload']['name']); $i++) { $filut[] = basename($_FILES['upload']['name'][$i]); } </code></pre> <p>(Note the addition of <code>[]</code> after <code>$filut</code>.)</p> <p>However, if this is what you were intending (to make $filut into an array) then you need to do something different down below in order to access just one element of the array. This is where a nested <code>foreach</code> would solve the problem - maybe this is how you intended to finish it off:</p> <pre><code>if(isset($_POST['subi'])) { $data1 = $_POST['answers']; foreach($data1 as $postValues) { foreach ($filut as $f) { $sql4 = 'INSERT INTO db_image (text, image) VALUES("'.$postValues.'","'.$f.'")'; $my->query($sql4); } } } </code></pre> <p>This will insert a row for every value in $filut for every value in $_POST['answers']. Is that what you wanted? Or are $filut and $_POST['answers'] in parallel and you want a 1-1 correlation on the insert?</p> <p>Finally I'm going to suggest that you use prepare and bind since you are getting your data from the user. This example copied/modified from <a href="http://php.net/manual/en/mysqli-stmt.execute.php" rel="nofollow">here</a>:</p> <pre><code><?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } /* Prepare an insert statement */ $query = "INSERT INTO db_image (text, image) VALUES (?,?)"; $stmt = $my->prepare($query); #### NOTE THE USE OF YOUR VARIABLES HERE IN THE BIND - the "ss" means they are strings $stmt->bind_param("ss", $postValues, $f); #### HERE IS WHERE YOUR CODE IS GETTING INSERTED foreach($data1 as $postValues) { foreach ($filut as $f) { /* Execute the statement */ $stmt->execute(); } } /* close statement */ $stmt->close(); /* close connection */ $my->close(); ?> </code></pre> <p>I can't guarantee that I got all the variables changed to match your code, but hopefully it's close enough to give you an idea. This solution (1) protects you from SQL Injection (which is a serious flaw in your code otherwise) and (2) will be much faster by means of the prepare/execute cycle.</p> <p><em>Do note the careful indentation in my examples where everything lines up perfectly with 3 or more spaces per indent - I can't tell you how many times I have seen sloppy (or too little) indentation make people miss problems which would be otherwise obvious.</em></p> |

If you do you will be writing your own implementation of <code>ArrayList</code> on the lines below it. In stead you just want to use the standard <code>ArrayList</code> so terminate that line and start a new one.</p> <p>I also changed <code>ArrayList<ArrayList<String>></code> to <code>List<List<String>></code> because you want to be able to put any <code>List</code> in there, not just <code>ArrayLists</code>. In fact what <code>Arrays.asList</code> creates is not an <code>ArrayList</code> so it wouldn't fit otherwise.</p> |

18,092,036 | 0 | Why is the GUI not working, is the code correct? <p>So Im trying to create 3 panels. The first panel has the layout set (e.g. the radio buttons and next button) I`m now adding two new panels which have different background colors. But when I execute the code I get an error of Null point exception. How do I fix that? </p> <p>Here is the code:</p> <pre><code>import java.awt.Color;import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.CardLayout; import javax.swing.*; public class Wizard { private JLabel lblPicture; private JRadioButton btLdap, btKerbegos, btSpnego, btSaml2; private JButton btNext; private JPanel panel; private JPanel panelFirst; private JPanel panelSecond; CardLayout c1 = new CardLayout(); public static void main(String[] args) { new Wizard(); } public Wizard() { JFrame frame = new JFrame("Wizard"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(600,360); frame.setVisible(true); MyPanel(); RadioButtons(); Button(); Image(); groupButton(); panel.setLayout(c1); panelFirst.setBackground(Color.BLUE); panelSecond.setBackground(Color.GREEN); panel.add(panelFirst,"1"); panel.add(panelSecond,"2"); c1.show(panel,"panel"); frame.add(panel); frame.pack(); frame.setVisible(true); } public void MyPanel() { panel = new JPanel(); panel.setLayout(null); } public void RadioButtons() { btLdap = new JRadioButton ("Ldap"); btLdap.setBounds(60,85,100,20); panel.add(btLdap); btKerbegos = new JRadioButton ("Kerbegos"); btKerbegos.setBounds(60,115,100,20); panel.add(btKerbegos); btSpnego =new JRadioButton("Spnego"); btSpnego.setBounds(60,145,100,20); panel.add(btSpnego); btSaml2 = new JRadioButton("Saml2"); btSaml2.setBounds(60,175,100,20); panel.add(btSaml2); } public void Button() { btNext = new JButton ("Next"); btNext.setBounds(400,260,100,20); panel.add(btNext); btNext.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { c1.show(panel, "2"); } }); } public void Image() { ImageIcon image = new ImageIcon("image.jpg"); lblPicture = new JLabel(image); lblPicture.setBounds(200,20, 330, 270); panel.add(lblPicture); } private void groupButton() { ButtonGroup bg1 = new ButtonGroup( ); bg1.add(btLdap); bg1.add(btKerbegos); bg1.add(btSpnego); bg1.add(btSaml2); } } </code></pre> |
34,552,278 | 1 | Can't see debug print statements using Google App Engine with python <p>I am new to both Google App Engine and Python. When things go wrong I'd like to see variable values and such, but print statements don't seem to be output anywhere. I would have expected them to appear in the same window where I started dev_appserver, but the only time I can see them is if a server error is imminent, then they appear in the output as I'd expect, right before the server error. Otherwise I don't see them.</p> <p>I'm sure I'm missing something very fundamental... it seems everyone else can see their print statements just fine. I have tried using the logger functionality, but best I can tell it is intended for deployed apps. At any rate I can't see any output from those either. A simple example:</p> <pre><code>class PageHandler(BaseHandler): def get(self): // the page renders just fine, but no print statement to be found print "rendering the page!" self.render("page.html") </code></pre> <p>Am I just looking in the wrong spot for the print output? Do I need to be doing something to redirect output before printing? Very confused why the print statements work only when an error is about to occur.</p> |
16,725,188 | 0 | <p>For those for whom the solution provided by cpowers and WonderGrub also didn't work, you should check out the following SO question, because for me this question was actually the answer to my occurence of this problem! <a href="http://stackoverflow.com/questions/7204840/rss20feedformatter-ignores-textsyndicationcontent-type-for-syndicationitem-summa">Rss20FeedFormatter Ignores TextSyndicationContent type for SyndicationItem.Summary</a></p> <p>Judging from the positive answer from <code>thelsdj</code> and <code>Andy Rose</code> and then later the 'negative' response from <code>TimLeung</code> and the alternative offered by <code>WonderGrub</code> I would estimate that the fix offered by cpowers stopped working in some later version of ASP.NET or something.</p> <p>In any case the solution in the above SO article (derived from David Whitney's code) solved the problem with unwanted HTML encoding in CDATA blocks in an RSS 2.0 feed for me. I used it in an ASP.NET 4.0 WebForms application.</p> |
