34,952,550 | 0 | Boost Spirit Qi : Is it suitable language/tool to analyse/cut a "multiline" data file? <p>I want to apply various operations to data files : algebra of sets, statistics, reporting, changes. But the format of the files is far from code examples and a bit weird. There are differents sorts of items, items type, and some of them are put together as a collection. There is a simplistic example below.<br> I'm new in boost::spirit and I have tried coding to split the items and get basic informations (name, version, date) required for most of treatments.

13,219,045 | 0 | <p>Whether or no a thread can process a timer callback within its own context depends entirely on how the timer expiry can be communicated to the thread. The thread must call the callback itself upon the receipt of some inter-thread comms, (eg. a WM_TIMER message received by a Windows GUI thread when it is waiting on its Windows message queue input). If the thread is not waiting for input, it cannot handle any inter-thread comms from any kind of timer and so cannot call any timer-handler callback within its own context.</p> <p>Forms.Timer, the C++ builder Timer component and other such are ways of arranging for interval-based inter-thread notifications - if a thread does not actively wait for and handle those notifications, there can be no timer callback in the context of that thread.</p> |
2,239,266 | 0 | Unit Testing Machine Learning Code <p>I am writing a fairly complicated machine learning program for my thesis in computer vision. It's working fairly well, but I need to keep trying out new things out and adding new functionality. This is problematic because I sometimes introduce bugs when I am extending the code or trying to simplify an algorithm.</p> <p>Clearly the correct thing to do is to add unit tests, but it is not clear how to do this. Many components of my program produce a somewhat subjective answer, and I cannot automate sanity checks.</p> <p>For example, I had some code that approximated a curve with a lower-resolution curve, so that I could do computationally intensive work on the lower-resolution curve. I accidentally introduced a bug into this code, and only found it through a painstaking search when my the results of my entire program got slightly worse.</p> <p>But, when I tried to write a unit-test for it, it was unclear what I should do. If I make a simple curve that has a clearly correct lower-resolution version, then I'm not really testing out everything that could go wrong. If I make a simple curve and then perturb the points slightly, my code starts producing different answers, even though this particular piece of code really seems to work fine now.</p> |

40,584,251 | 0 | Azure portal metrics weird numbers <p>I'm trying to view our peak bytes received/sec count for an eventhub in order to scale it properly.

1,750,786 | 0 | In nHibernate, can I map an abstract base class to a collection? <p>I have a base class for content items in a CMS I'm building. It's currently marked abstract because I only want derived classes to be instantiated. Derived classes like BlogPost, Article, Photo, etc. are set up as a joined subclass to my ContentBase class in nHibernate.</p> <p>I'm trying to set up a many-to-many mapping between this class and a Tag class. I want to have a collection of Tags on the ContentBase class, and a collection of ContentBase items on the tag class.</p> <p>Will nHibernate allow me to map the abstract ContentBase class as a collection on the Tag class? I'm assuming not since it wouldn't be able to instantiate any instances of this class when reconstituting a Tag entity from the db. I really don't want to have to have to use a collection of content items per type (e.g. TaggedBlogPosts, TaggedArticles, etc.) on the Tag class.</p> <p>The whole reason I'm doing this is because logically, a content item can have many tags, and 1 tag can belong to multiple content items. in order for nHibernate to manage the relationships for me in a mapping table, I believe I have to set up a many-to-many association and add the Tag to the ContentBase.Tags collection and then the content item to the Tags.TaggedContentItems collection before the mapping table entry is created in nHibernate.</p> <p>Here are my mappings for reference:</p> <pre><code> <class name="CMS.Core.Model.Tag,CMS.Core" table="bp_Tags"> <id column="TagName" name="TagName" type="String" unsaved-value=""> <generator class="assigned" /> </id> <bag name="_taggedContentList" table="bp_Tags_Mappings" inverse="true" cascade="save-update" lazy="true"> <key column="TagName" /> <many-to-many class="CMS.Core.Model.ContentBase,CMS.Core" column="Target_Id" /> </bag> </class> <class name="CMS.Core.Model.ContentBase,CMS.Core" table="bp_Content"> <id name="Id" column="Id" type="Int32" unsaved-value="0"> <generator class="native"></generator> </id> <property name="SubmittedBy" column="SubmittedBy" type="string" length="256" not-null="true" /> <property name="SubmittedDate" column="SubmittedDate" type="datetime" not-null="true" /> <property name="PublishDate" column="PublishDate" type="datetime" not-null="true" /> <property name="State" column="State" type="CMS.Core.Model.ContentStates,CMS.Core" not-null="true" /> <property name="ContentType" column="ContentType" type="CMS.Core.Model.ContentTypes,CMS.Core" not-null="true" /> <bag name="_tagsList" table="bp_Tags_Mappings" lazy="false" cascade="save-update"> <key column="Target_Id" /> <many-to-many class="CMS.Core.Model.Tag,CMS.Core" column="TagName" lazy="false" /> </bag> ... <joined-subclass name="CMS.Core.Model.BlogPost,CMS.Core" table="bp_Content_BlogPosts" > <key column="Id" /> <property name="Body" type="string" column="Body" /> <property name="Title" type="string" column="Title" /> </joined-subclass> ... </code></pre> |

1,404,833 | 0 | <p>The answer suggested; [theTableView reload] definitely works fine. If you update the table every view seconds, however, your users will going to hate you and down-vote your app. No question.</p> <p>Try to capture the reloading data in a notification handler. In that handler, check if the updated data belongs somewhere between the currently visible cells, if so, update the currently visible view. If not, ignore the updated data (but do add it to your underlying model). If the user scrolls further, after your update, cellForIndexPath: is called and the updated data will be drawn automatically.</p> <p>reload is quite heavy to do every view seconds, certainly with a lot of data. drawing might get screwed up or worse..</p> |

27,029,136 | 0 | Spring security ldap connection management <p>I am using spring security to authenticate users logging into a webapp. Authentication is currently done with ldap.</p> <p>Between my webapp and my ldap server lies a firewall. After 50 minutes of inactivity, the firewall flushes idle ldap connections.</p> <p>Spring security sometimes reuses existing connections, but not always. If it picks a connection closed by my firewall, the login will fail. </p> <p>The exception I find in my Tomcat log is the following.</p> <pre><code>org.springframework.ldap.ServiceUnavailableException: ldap:389; socket closed; nested exception is javax.naming.ServiceUnavailableException </code></pre> <p>More specifically, connections causing issues are the ones used for search requests. They're not systematically closed by the framework. Bind requests are always made on a new connection that's closed at the end of the request.</p> <p>In my app a search request is issued after a bind because of a custom LdapAuthoritiesPopulator granting access only to users with particular roles. I have verified the default LdapAuthoritiesPopulator issues search requests in the same manner.</p> <p>Is it normal for search request connections to stay open almost indefinitely? If it is, is there a way I can change the way spring security manages its connections?</p> <p>I'm also interested to know if there is a better way than using a custom LdapAuthoritiesPopulator to enforce a role constraint during authentication.</p> <p>My problem persists after trying easy upgrades:</p> <ul> <li>spring-security 3.1.7 (up from 3.1.2) </li> <li>spring-ldap-core 2.0.2 (up from 1.3.0) </li> <li>spring-ldap 1.3.1 (up from 1.3.0)</li> </ul> <p>Thanks.</p> |

However this solution doesn't fully answers the question. In the case the text of JLabel contains HTML decorations the <code>metrics.stringWidth()</code> would also calculate width of HTML tags. So it could happen that result of <code>metrics.stringWidth()</code> would be grater than JLabel's width but still the text would be displayed correctly.</p> <p>Is there a way know what decision took the JLabel itself while displaying the text. Has it decided to truncate the text or not.</p> |

14,750,533 | 0 | <p>I have tidied up your query a little (although this won't make a massive amount of difference to performance, and there may be typos as I don't have VS to hand). From your edit it seems you are a little confused by deferred execution in LINQ. <code>callDetailsForNodes</code> does not represent your results - it is a query that will provide your results once it is executed.</p> <p>If you have to do all this querying in process I suggest you add a <code>ToList</code> after the first select and run that in isolation. Then add <code>ToList</code> to the <code>Where</code> clause. Calling <code>ToList</code> will force your query to execute and you will see where the delays are.</p> <p>One final note - you should pass your records directly to <code>ObservableCollection</code> constructor rather than calling <code>Add</code> for each item. Calling <code>Add</code> will (I think) cause the collection to raise a changed notification which is not a big deal for small lists but will slow things down for larger lists.</p> <pre><code>var callDetailsForNodes = dtRowForNode.AsEnumerable() .Select(dr => new { caller1 = StringComparer.CurrentCultureIgnoreCase.Compare(dr["F1"], dr["F2"]) < 0 ? dr["F1"] : dr["F2"], caller2 = StringComparer.CurrentCultureIgnoreCase.Compare(dr["F1"], dr["F2"]) < 0 ? dr["F2"] : dr["F1"], time = Convert.ToDateTime(dr["F3"]), filters = dr.Field<string>("F9")}) .Where(dr => (dtMin <= dr.time) && (dtMax >= dr.time) && (lstCallType.Contains(dr.filters)) && (dtMinTime <= dr.time.TimeOfDay) && (dtMaxTime >= dr.time.TimeOfDay) && caller1 == VerSelected || caller2 == VerSelected)) .GroupBy(drg => new { drg.caller1, drg.caller2 }) .Select(drg => new { drg.Key.caller1, drg.Key.caller2, count = drg.Count()); </code></pre> |

20,786,199 | 0 | <p>By keeping a circular buffer of runes, you can minimise allocations.

27,546,567 | 0 | What in this code is causing a Seg fault? <p>I am very new to Assembly programming and to learn NASM I decided to try and write a prime number testing. I wrote the code for the <code>is_prime</code> function in 32-bit elf NASM and wrote a wrapper in c++ that uses externs the NASM function. When I compiled both programs to <code>.o</code> files there were no errors, and when I linked the object files to make an executable it linked correctly. However when I try to run it I keep getting a <code>Segmentation Fault</code> error and I have no idea what this actually means or how to correct it. The code that I wrote in NASM looks like this:</p> <pre><code>section .bss n: resb 1 i: resb 1 m: resb 1 section .text global is_prime is_prime: push ebp mov ebp,esp mov eax,[ebp + 8] jmp main main: mov [n],eax mov byte [i],2 mov eax,[i] mov ebx,[n] cmp eax,ebx jge prime mov eax,[i] mov ebx,[n] call mod cmp byte [m],0 je comp jmp main mod: mov ecx,ebx xor edx,edx div ecx mov [m],edx ret comp: mov eax,0 jmp kill prime: mov eax,1 jmp kill kill: ret leave </code></pre> <p>My main question is, am I doing something wrong in my assembly program that is causing this error and if so, how do I fix this? Or is there something wrong in the way I am linking/compiling it? I am using a 64-bit Ubuntu but I used the <code>-m32</code> and <code>-f elf32</code> options while compiling. </p> |
