• Can Drupal Taxonomy module be used to categorize court records and briefs?

  - by DKinzer

  I'm currently working on project that involves moving a database of documents for court records and briefs over to a Drupal environment. One of the problems that we are faced with is how to index these documents. In our court district, records and briefs all have a docket number which is assigned to a case. The interesting thing is that when multiple cases merge the docket numbers associated to the case become synonymous: Case 1, documents have Doceket No. A Case 2, documents have Docket No. B If case Cases 1 and Case 2 merge, then Docket No. A = Docket No. B My first inclination is to create Docket Vocabulary and have the terms of this Taxonomy be the docket numbers. I am hoping to take advantage of the fact that terms can be synonymous. I understand that there are several functions in the Taxonomy module that I may be able to take advantage, of including: taxonomy_get_synonyms taxonomy_get_related But I'm having problems convincing my collegues that this is the way to go, and frankly I'm not certain it's the right solution either. If anyone has had a similar issue and can offer some guidance as to how to move forward, I would greatly appreciate it. Thanks! D I've asked a related question (which I would also need to answer in order to move forward with this solution): http://stackoverflow.com/questions/2656247/can-drupal-terms-in-different-taxonomies-be-synonymous

• iTunes Connect uploading issue

  - by CindySeattle

  Too bad that iTunes Connect changed its behavior recently. I'm providing an update to an existing app. I submitted new binary using the Loader without problem on the first try. Then I discovered that different from before, one has to reject the binaries in order to change screenshots. Too bad that the update is in the status of "In Review". Well, I have to rejected my binaries and begin to upload new screenshots, because I don't want to display screenshots of previous version. The new screen shots are uploaded but I'm stuck in "Developer rejected" status. Meaning I cannot upload the binaries and not able to change screenshots from that time on. The following error will appear when click Save Changes in either situations. "There was an error saving changes. Please try again later or contact iTunes Connect Support at [email protected]." I checked the source of the error page and think it's this error id="lcBoxWrapperHeaderTextUpdaterContainer" action="/WebObjects/iTunesConnect.woa/wo/7.0.0.9.7.7.1.1.1.1" errorId="ajaxContainerError" I have reported iTune Connect via the "Contact us" link on this issue but not get any response back for 2 days already. Very disappointing. Did anybody experience similar issue? How did you resolve this?

• Alternate colors on click with jQuery

  - by Jace Cotton

  I'm sure there is a simple solution to this, and I'm sure this is a duplicate question, though I have been unable to solve my solution particularly because I don't really know how to phrase it in order to search for other questions/solutions, so I'm coming here hoping for some help. Basically, I have spans with classes that assigns a background-color property, and inside those spans are words. I have three of these spans, and each time a user clicks on a span I want the class to change (thus changing the background color and inner text). HTML: <span class="alternate"> <span class="blue showing">Lorem</span> <span class="green">Ipsum</span> <span class="red">Dolor</span> </span> CSS: .alternate span { display : none } .alternate .showing { display : inline } .blue { background : blue } .green { background : green } .red { background : red } jQuery: $(".alternate span").each(function() { $(this).on("click", function() { $(this).removeClass("showing"); $(this).next().addClass("showing"); }); }); This solution works great using $.next until I get to the third click, whereafter .showing is removed, and is not added since there are no more $.next options. How do I, after getting to the last-child, add .showing to the first-child and then start over? I have tried various options including if($(".alternate span:last-child").hasClass("showing")) { etc. etc. }, and I attempted to use an array and for loop though I failed to make it work. Newb question, I know, but I can't seem to solve this so as a last resort I'm coming here.

• Django Admin Running Same Query Thousands of Times for Model

  - by Tom

  Running into an odd . . . loop when trying to view a model in the Django admin. I have three related models (code trimmed for brevity, hopefully I didn't trim something I shouldn't have): class Association(models.Model): somecompany_entity_id = models.CharField(max_length=10, db_index=True) name = models.CharField(max_length=200) def __unicode__(self): return self.name class ResidentialUnit(models.Model): building = models.CharField(max_length=10) app_number = models.CharField(max_length=10) unit_number = models.CharField(max_length=10) unit_description = models.CharField(max_length=100, blank=True) association = models.ForeignKey(Association) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) def __unicode__(self): return '%s: %s, Unit %s' % (self.association, self.building, self.unit_number) class Resident(models.Model): unit = models.ForeignKey(ResidentialUnit) type = models.CharField(max_length=20, blank=True, default='') lookup_key = models.CharField(max_length=200) jenark_id = models.CharField(max_length=20, blank=True) user = models.ForeignKey(User) is_association_admin = models.BooleanField(default=False, db_index=True) show_in_contact_list = models.BooleanField(default=False, db_index=True) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) _phones = {} home_phone = None work_phone = None cell_phone = None app_number = None account_cache_key = None def __unicode__(self): return '%s' % self.user.get_full_name() It's the last model that's causing the problem. Trying to look at a Resident in the admin takes 10-20 seconds. If I take 'self.association' out of the __unicode__ method for ResidentialUnit, a resident page renders pretty quickly. Looking at it in the debug toolbar, without the association name in ResidentialUnit (which is a foreign key on Resident), the page runs 14 queries. With the association name put back in, it runs a far more impressive 4,872 queries. The strangest part is the extra queries all seem to be looking up the association name. They all come from the same line, the __unicode__ method for ResidentialUnit. Each one is the exact same thing, e.g., SELECT `residents_association`.`id`, `residents_association`.`jenark_entity_id`, `residents_association`.`name` FROM `residents_association` WHERE `residents_association`.`id` = 1096 ORDER BY `residents_association`.`name` ASC I assume I've managed to create a circular reference, but if it were truly circular, it would just die, not run 4000x and then return. Having trouble finding a good Google or StackOverflow result for this.

• efficient thread-safe singleton in C++

  - by user168715

  The usual pattern for a singleton class is something like static Foo &getInst() { static Foo *inst = NULL; if(inst == NULL) inst = new Foo(...); return *inst; } However, it's my understanding that this solution is not thread-safe, since 1) Foo's constructor might be called more than once (which may or may not matter) and 2) inst may not be fully constructed before it is returned to a different thread. One solution is to wrap a mutex around the whole method, but then I'm paying for synchronization overhead long after I actually need it. An alternative is something like static Foo &getInst() { static Foo *inst = NULL; if(inst == NULL) { pthread_mutex_lock(&mutex); if(inst == NULL) inst = new Foo(...); pthread_mutex_unlock(&mutex); } return *inst; } Is this the right way to do it, or are there any pitfalls I should be aware of? For instance, are there any static initialization order problems that might occur, i.e. is inst always guaranteed to be NULL the first time getInst is called?

• Where to add an overloaded operator for the tr1::array?

  - by phlipsy

  Since I need to add an operator& for the std::tr1::array<bool, N> I wrote the following lines template<std::size_t N> std::tr1::array<bool, N> operator& (const std::tr1::array<bool, N>& a, const std::tr1::array<bool, N>& b) { std::tr1::array<bool, N> result; std::transform(a.begin(), a.end(), b.begin(), result.begin(), std::logical_and<bool>()); return result; } Now I don't know in which namespace I've to put this function. I considered the std namespace as a restricted area. Only total specialization and overloaded function templates are allowed to be added by the user. Putting it into the global namespace isn't "allowed" either in order to prevent pollution of the global namespace and clashes with other declarations. And finally putting this function into the namespace of the project doesn't work since the compiler won't find it there. What had I best do? I don't want to write a new array class putted into the project namespace. Because in this case the compiler would find the right namespace via argument dependent name lookup. Or is this the only possible way because writing a new operator for existing classes means extending their interfaces and this isn't allowed either for standard classes?

• Elegant way to import XHTML nodes from xhr.responseXML into HTML document in IE?

  - by Weston Ruter

  While navigating through a site, I'm dynamically loading pages via Ajax and then only updating the elements of the page that are changed, such as the navigation state and main content area. This is similar to Lala. I am serving the site as XHTML in order to be able to have access to xhr.responseXML which I then traverse in parallel with the current document and copy the nodes over. This works very well in browsers other than IE. For IE, I have to iterate over all of the properties of each XML element I want to import into the HTML document to create it from scratch (using a function convertXMLElementToHTML()). Here's the code I'm currently using: try { nodeB = document.importNode(nodeB, true); } catch(e){ nodeB = nodeB.cloneNode(true); if(document.adoptNode) document.adoptNode(nodeB); } try { //This works in all browsers other than IE nodeA.parentNode.replaceChild(nodeB, nodeA); } //Manually clone the nodes into HTML; required for IE catch(e){ nodeA.parentNode.replaceChild(convertXMLElementToHTML(nodeB), nodeA); } Is there a more elegant solution to mirror-translating XML nodes into HTML?

• WordPress update_post_meta values. Delete when empty or just test for ""?

  - by Scott B

  My function below, will take the values from my custom meta fields (after a post has been edited, and save or publish has been clicked) and update or insert the posted meta values. However, if the user leaves this field blank, I believe I want to delete the meta altogether (so I can test for its presence and display accordingly vs just checking for ""). For example, one of my meta options gives the user the ability to add a Custom title to their post, which when present, will populate the page's tag. However, if the field is left empty, I want to default the tag to the_title(), which is simply the Post title used to identify the page/post. Since I'm not deleting the meta on save, its always present after the first time a user enters something in there, get_post_meta($post-ID,'MyCustomTitle', true) is always true. Further, they cannot blank it out by clearing the title field and hitting publish. What am I missing in the save in order to clear the value to "" when the user clears the field? if ($_POST['MyCustomTitle']) { update_custom_meta($postID, $_POST['MyCustomTitle'], 'MyCustomTitle'); } function update_custom_meta($postID, $newvalue, $field_name) { // To create new meta if(!get_post_meta($postID, $field_name)){ add_post_meta($postID, $field_name, $newvalue); }else{ // or to update existing meta update_post_meta($postID, $field_name, $newvalue); } }

• find and replace values in csv using PHP

  - by peirix

  I'd think there was a question on this already, but I can't find one. Maybe the solution is too easy... Anyway, I have a csv and want to let the user change the values based on a name. I've already sorted out creating new name+value-pairs using the fopen('a') mode, using jQuery to send the AJAX call with newValue and newName. But say the content looks like this: host|http:www.stackoverflow.com folder|/questions/ folder2|/users/ And now I want to change the folder value. So I'll send in folder as oldName and /tags/ as newValue. What's the best way to overwrite the value? The order in the list doesn't matter, and the name will always be on the left, followed by a |(pipe), the value and then a new-line. My first thought was to read the list, store it in an array, search all the [0]'s for oldName, then change the [1] that belongs to it, and then write it back to a file. But I feel there is a better way around this? Any ideas? Maybe regex?

• Passing arguments and conditions to model in codeigniter

  - by stormdrain

  I'm adding some models to a project, and was wondering if there is a "best practice" kind of approach to creating models: Does it make sense to create a function for each specific query? I was starting to do this, then had the idea of creating a generic function that I could pass parameters to. e.g: Instead of function getClients(){ return $this->db->query('SELECT client_id,last FROM Names ORDER BY id DESC'); } function getClientNames($clid){ return $this->db->query('SELECT * FROM Names WHERE client_id = '.$clid); } function getClientName($nameID){ return $this->db->query('SELECT * FROM Names WHERE id ='.$nameID); } } Something like function getNameData($args,$cond){ if($cond==''){ $q=$this->db->query('SELECT '.$args.' FROM Names'); return $q; }else{ $q=$this->db->query('SELECT '.$args.' FROM Names WHERE '.$cond); return $q; } } where I can pass the fields and conditions (if applicable) to the model. Is there a reason the latter example would be a bad idea? Thanks!

• Where to start with map application

  - by rfders

  Hi there, i'm trying to desing a new application which allow user see he/her current location on a custom map (office, university compus, etc). but actually i have a couple of question in my mind (i haven't designed this kind of application before). i'm wondering: How can i draw my own maps, what is the best option for it? there any format that i have to care of, there are any specification about it ? Once i have my custom map. how can i do to mapping a global position system with the local positions ? What are the tricks behing zoom on maps ? just differents layers with more or less informations and those layers changes on users demand ? If a whant to mark some specific points over the map, like a cafeteria, boss's office etc, how can i do that ? Sorry if my questions are too much generics and dumb, but i really need some clues about this topic because i don't have any idea how to design this kind of application as best as possible. and we don't whant to reinvent the wheel. I will appreciate any help that you can provide me in order to desing this application

• escape exactly what in javascript

  - by Emin

  Hi all, Being a newbie in javascript I came to a situation where I need more information on escaping characters in a string. Basically I know that in order to escape " I need to replace it with \" but what I don't know is for which characters I need to escape a particular string for. Is there a list of these "characters to escape"? or is it any character that is not a-zA-Z0-9 ? In my situation, I don't have control over the content that is being displayed on my page. Users enter some text and save it. I then use a webservice to extract them from the database, build a json array of objects, then iterate the array when I need to display them. In this case, I have - naturally - no idea of what the text the user has entered and therefore for what characters I need to escape. I also use jQuery for this specific project (just in case it has a function I am not aware of, to do what I need) Providing examples would be appreciated but I also want to learn the theory and logic behind it. Hope someone can be of any help.

• How to reset the context to the original rectangle after clipping it for drawing?

  - by mystify

  I try to draw a sequence of pattern images (different repeated patterns in one view). So what I did is this, in a loop: CGContextRef context = UIGraphicsGetCurrentContext(); // clip to the drawing rectangle to draw the pattern for this portion of the view CGContextClipToRect(context, drawingRect); // the first call here works fine... but for the next nothing will be drawn CGContextDrawTiledImage(context, CGRectMake(0, 0, 2, 31), [img CGImage]); I think that after I've clipped the context to draw the pattern in the specific rectangle, I cut out a snippet from the big canvas and the next time, my canvas is gone. can't cut out another snippet. So I must reset that clipping somehow in order to be able to draw another pattern again somewhere else? Edit: In the documentation I found this: CGContextClip: "... Therefore, to re-enlarge the paintable area by restoring the clipping path to a prior state, you must save the graphics state before you clip and restore the graphics state after you’ve completed any clipped drawing. ..." Well then, how to store the graphics state before clipping and how to restore it?

• Help on MySQL table indexing when GROUP BY is used in a query

  - by Silver Light

  Thank you for your attention. There are two INNODB tables: Table authors id INT nickname VARCHAR(50) status ENUM('active', 'blocked') about TEXT Table books author_id INT title VARCHAR(150) I'm running a query against these tables, to get each author and a count of books he has: SELECT a. * , COUNT( b.id ) AS book_count FROM authors AS a, books AS b WHERE a.status != 'blocked' AND b.author_id = a.id GROUP BY a.id ORDER BY a.nickname This query is very slow (takes about 6 seconds to execute). I have an index on books.author_id and it works perfectly, but I do not know how to create an index on authors table, so that this query could use it. Here is how current EXPLAIN looks: id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE a ALL PRIMARY,id_status_nickname NULL NULL NULL 3305 Using where; Using temporary; Using filesort 1 SIMPLE b ref key_author_id key_author_id 5 a.id 2 Using where; Using index I've looked at MySQL manual on optimizing queries with group by, but could not figure out how I can apply it on my query. I'll appreciate any help and hints on this - what must be the index structure, so that MySQL could use it?

• Interview Q: sorting an almost sorted array (elements misplaced by no more than k)

  - by polygenelubricants

  I was asked this interview question recently: You're given an array that is almost sorted, in that each of the N elements may be misplaced by no more than k positions from the correct sorted order. Find a space-and-time efficient algorithm to sort the array. I have an O(N log k) solution as follows. Let's denote arr[0..n) to mean the elements of the array from index 0 (inclusive) to N (exclusive). Sort arr[0..2k) Now we know that arr[0..k) are in their final sorted positions... ...but arr[k..2k) may still be misplaced by k! Sort arr[k..3k) Now we know that arr[k..2k) are in their final sorted positions... ...but arr[2k..3k) may still be misplaced by k Sort arr[2k..4k) .... Until you sort arr[ik..N), then you're done! This final step may be cheaper than the other steps when you have less than 2k elements left In each step, you sort at most 2k elements in O(k log k), putting at least k elements in their final sorted positions at the end of each step. There are O(N/k) steps, so the overall complexity is O(N log k). My questions are: Is O(N log k) optimal? Can this be improved upon? Can you do this without (partially) re-sorting the same elements?

• Ways to make (relatively) safe assumptions about the type of concrete subclasses?

  - by Kylotan

  I have an interface (defined as a abstract base class) that looks like this: class AbstractInterface { public: bool IsRelatedTo(const AbstractInterface& other) const = 0; } And I have an implementation of this (constructors etc omitted): class ConcreteThing { public: bool IsRelatedTo(const AbstractInterface& other) const { return m_ImplObject.has_relationship_to(other.m_ImplObject); } private: ImplementationObject m_ImplObject; } The AbstractInterface forms an interface in Project A, and the ConcreteThing lives in Project B as an implementation of that interface. This is so that code in Project A can access data from Project B without having a direct dependency on it - Project B just has to implement the correct interface. Obviously the line in the body of the IsRelatedTo function cannot compile - that instance of ConcreteThing has an m_ImplObject member, but it can't assume that all AbstractInterfaces do, including the other argument. In my system, I can actually assume that all implementations of AbstractInterface are instances of ConcreteThing (or subclasses thereof), but I'd prefer not to be casting the object to the concrete type in order to get at the private member, or encoding that assumption in a way that will crash without a diagnostic later if this assumption ceases to hold true. I cannot modify ImplementationObject, but I can modify AbstractInterface and ConcreteThing. I also cannot use the standard RTTI mechanism for checking a type prior to casting, or use dynamic_cast for a similar purpose. I have a feeling that I might be able to overload IsRelatedTo with a ConcreteThing argument, but I'm not sure how to call it via the base IsRelatedTo(AbstractInterface) method. It wouldn't get called automatically as it's not a strict reimplementation of that method. Is there a pattern for doing what I want here, allowing me to implement the IsRelatedTo function via ImplementationObject::has_relationship_to(ImplementationObject), without risky casts? (Also, I couldn't think of a good question title - please change it if you have a better one.)

• List with non-null elements ends up containing null. A synchronization issue?

  - by Alix

  Hi. First of all, sorry about the title -- I couldn't figure out one that was short and clear enough. Here's the issue: I have a list List<MyClass> list to which I always add newly-created instances of MyClass, like this: list.Add(new MyClass()). I don't add elements any other way. However, then I iterate over the list with foreach and find that there are some null entries. That is, the following code: foreach (MyClass entry in list) if (entry == null) throw new Exception("null entry!"); will sometimes throw an exception. I should point out that the list.Add(new MyClass()) are performed from different threads running concurrently. The only thing I can think of to account for the null entries is the concurrent accesses. List<> isn't thread-safe, after all. Though I still find it strange that it ends up containing null entries, instead of just not offering any guarantees on ordering. Can you think of any other reason? Also, I don't care in which order the items are added, and I don't want the calling threads to block waiting to add their items. If synchronization is truly the issue, can you recommend a simple way to call the Add method asynchronously, i.e., create a delegate that takes care of that while my thread keeps running its code? I know I can create a delegate for Add and call BeginInvoke on it. Does that seem appropriate? Thanks.

• What is the best way to get a reference to a spring bean in the backend layers?

  - by java_pill

  I have two spring config files and I'm specifying them in my web.xml as in below. web.xml snippet .. <context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/classes/domain-context.xml WEB-INF/classes/client-ws.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> .. From my domain object I have to invoke a Web Service Client and in order to get a reference to the Web Service client I do this: ApplicationContext context = new ClassPathXmlApplicationContext("client-ws.xml"); //b'cos I don't want to use WebApplicationContextUtils ProductServiceClient client = (ProductServiceClient) context.getBean("productClient"); .. client.find(prodID); //calls a Web Service .. However, I have concerns that looking up the client-ws.xml file and getting a reference to the ProductServiceClient bean is not efficient. I thought of getting it using WebApplicationContextUtils. However, I don't want my domain objects to have a dependency on the ServletContext (a web/control layer object) because WebApplicationContextUtils depends on ServletContext. What is the best way to get a reference to a spring bean in the backend layers? Thanks!

• Why is there so much XML in Java these days?

  - by BD at Rivenhill

  This is really more of a philosophy/design issue. I did some work in Java back in the middle 90's and again in the early 2000's and now I'm coming back to it after spending a lot of time in C/C++ and it seems like there was an explosion of XML dependency while I was gone. Major build system tools like ant and maven depend on XML for their configuration, but I'm actually more concerned with all the frameworks, such as Spring, Hibernate, etc. My experience is that powerful supporting libraries like these are where a developer can really get leverage for building programs with lots of features without writing a lot of code, but it really seems like I'm getting one language for the price of two here. I write a bunch of Java classes, but then I also write a bunch of XML files to glue them together. The things that get done in the XML are things that I can see reasonable ways of doing in straight code without the middleman, and they don't really seem to be treated exactly like configuration files: they change rarely and they end up getting committed to source code control like the Java code itself, but they are distributed with the resulting application and need to be unpacked and installed in the classpath in order to get the application to work. I'm working with server applications that are not web-based, so maybe the domain is a bit different from what most people are doing, but I just can't help feeling that I must be doing something wrong here. Can someone point me to a good source of information for why these design choices were made and what problems they are meant to solve so that I can analyze my own experiences in this context?

• How to convert a byte array of 19200 bytes in size where each byte represents 4 pixels (2 bits per p

  - by Klinger

  I am communicating with an instrument (remote controlling it) and one of the things I need to do is to draw the instrument screen. In order to get the screen I issue a command and the instrument replies with an array of bytes that represents the screen. Below is what the instrument manual has to say about converting the response to the actual screen: The command retrieves the framebuffer data used for the display. It is 19200 bytes in size, 2-bits per pixel, 4 pixels per byte arranged as 320x240 characteres. The data is sent in RLE encoded form. To convert this data into a BMP for use in Windows, it needs to be turned into a 4BPP. Also note that BMP files are upside down relative to this data, i.e. the top display line is the last line in the BMP. I managed to unpack the data, but now I am stuck on how to actually go from the unpacked byte array to a bitmap. My background on this is pretty close to zero and my searches have not revealed much either. I am looking for directions and/or articles I could use to help me undestand how to get this done. Any code or even pseudo code would also help. :-) So, just to summarize it all: How to convert a byte array of 19200 bytes in size, where each byte represents 4 pixels (2 bits per pixel), to a bitmap arranged as 320x240 characters. Thanks in advance.

VerbPhrase will call on NounPhrase half the time and it's output the output should be something to the effect of: the empty lot re-animates this pyramid (bold indicating where generateNounPhrase() is logically called). The true output however is in the form of: the empty lot re-animates the empty lot At first I thought my randomIndex method wasn't working as I had intended, but if I run the two methods again I do get different noun phrases but they are not unique at the beginning and end of the sentence as they should be. Any idea what I am doing wrong in order to get one method to show the same result? private string generateNounPhrase() { string nounPhraseString = ""; nounPhraseString = nounMarkersStringList[randomIndex(0,nounMarkersStringList.Count-1)]; if (included(1, 4, 2) == true) { nounPhraseString += " " + adjectivesStringList[randomIndex(0, adjectivesStringList.Count - 1)]; } nounPhraseString += " " + nounsStringList[randomIndex(0, nounsStringList.Count - 1)]; return nounPhraseString; } private string generateVerbPhrase() { string verbPhraseString = ""; if (included(1, 4, 2) == true) { verbPhraseString = intransitiveVerbsStringList[randomIndex(0, intransitiveVerbsStringList.Count - 1)]; } else { verbPhraseString = transitiveVerbsStringList[randomIndex(0, transitiveVerbsStringList.Count - 1)] + " " + generateNounPhrase(); } return verbPhraseString; }

• Starting a process synchronously, and "streaming" the output

  - by Benjol

  I'm looking at trying to start a process from F#, wait till it's finished, but also read it's output progressively. Is this the right/best way to do it? (In my case I'm trying to execute git commands, but that is tangential to the question) let gitexecute (logger:string->unit) cmd = let procStartInfo = new ProcessStartInfo(@"C:\Program Files\Git\bin\git.exe", cmd) // Redirect to the Process.StandardOutput StreamReader. procStartInfo.RedirectStandardOutput <- true procStartInfo.UseShellExecute <- false; // Do not create the black window. procStartInfo.CreateNoWindow <- true; // Create a process, assign its ProcessStartInfo and start it let proc = new Process(); proc.StartInfo <- procStartInfo; proc.Start() |> ignore // Get the output into a string while not proc.StandardOutput.EndOfStream do proc.StandardOutput.ReadLine() |> logger What I don't understand is how the proc.Start() can return a boolean and also be asynchronous enough for me to get the output out of the while progressively. Unfortunately, I don't currently have a large enough repository - or slow enough machine, to be able to tell what order things are happening in...

• C++ std::vector memory/allocation

  - by aaa

  from a previous question about vector capacity, http://stackoverflow.com/questions/2663170/stdvector-capacity-after-copying, Mr. Bailey said: In current C++ you are guaranteed that no reallocation occurs after a call to reserve until an insertion would take the size beyond the value of the previous call to reserve. Before a call to reserve, or after a call to reserve when the size is between the value of the previous call to reserve and the capacity the implementation is allowed to reallocate early if it so chooses. So, if I understand correctly, in order to assure that no relocation happens until capacity is exceeded, I must do reserve twice? can you please clarify it? I am using vector as a memory stack like this: std::vector<double> memory; memory.reserve(size); memory.insert(memory.end(), matrix.data().begin(), matrix.data().end()); // smaller than size size_t offset = memory.size(); memory.resize(memory.capacity(), 0); I need to guarantee that relocation does not happen in the above. thank you. ps: I would also like to know if there is a better way to manage memory stack in similar manner other than vector
