| How to end FreeMarker processing prematurely in normal way? Posted: 10 Sep 2021 08:00 AM PDT I'd like to exit early from processing a FreeMarker template (to reduce indentation compared to wrapping a lot of code in a conditional). Like: <#if !precondition><#-- End processing --></#if> <#-- Do something if precondition met -->
I've been reading through the docs for <#stop> which say This must not be used for ending template processing in normal situations! but unfortunately the docs forget to say what is the way to end template processing in normal situations.  |
| Rsquared Values for Complex Indicators in CFA Using Lavaan Posted: 10 Sep 2021 08:00 AM PDT I'm trying to find the Rsquared value for a complex indicator (an indicator that loads onto two factors) using Lavaan. Normally you can just square the standardized loading to get the Rsquared value or use the parameterestimates function. However, when I model an indicator as loading onto two factors parameterestimates only gives 1 rsquared value for the complex indicator. Is there a way to determine the variance explained from each of the factors? Here is my code: model <- ' field_belong =~ V8FBL1 + V8FBL2 + V8FBL3 + V8FBL4 + V8FBL5 + V8FID1 field_identity =~ V8FID1 + V8FID2 + V8FID3 ' fit <- cfa(model, data = ltfu, missing = "fiml") summary(fit, fit.measures = TRUE, standardized = TRUE) par_est <- parameterestimates(fit, rsquare = T)
I am trying to get rsquared values for V8FID1 for both factors. Overall, I want to know the percent of variance explained in the V8FID1 variables by field_belong and field_identity separately.  |
| Cloud functions for multiples files gcp bucket events Posted: 10 Sep 2021 07:59 AM PDT I'm creating a Cloud Function in GCP to automatically resize images uploaded to a bucket and transfer them to another bucket. Since the images arrive in batches and one folder might contain hundreds or thousands of images, is it better to incorporate in the code the ability to deal with the multiple files or is better to let cloud functions be triggered on every image uploaded.  |
| Take an object from an array of objects based on the max value on one of its properties Posted: 10 Sep 2021 07:59 AM PDT Let's say I got an array of object like this a = [ {name: John, age: 15}, {name: Max, age: 17}, {name: Tom, age: 11}, ]
How can I take just the object containing Max, 17? This would be the result b = [ {name: Max, age: 17} ]
or better c = {name: Max, age: 17}

| How to display the logged in user details in a table format using session in node js , react js , sql? Posted: 10 Sep 2021 07:59 AM PDT This the view page where user details are redirected Hello all currently i am working on a project which has two form login and user details form. When users login and fills the details form after that it will redirect it to view page where he/she can view, edit ,delete his/her record. But when user login only his records should be seen. In my case it is fetching all the records in a view page. I am using session in node js. I don't know what's gone wrong.

| Work with different tabs, of the Notebook tkinter Posted: 10 Sep 2021 07:59 AM PDT I have a question or problem, maybe there is an answer, but I still can't understand. I have an application, which works with several Notebook tabs Main When I click on any button, it calls me a function that in turn works with a class where it creates me, the tab and the widgets: def open_issuesDeviation (self): global deviation deviation = Deviation (self.root) self.book.add (deviation, text = 'Issues DEVIATIONS') self.book.select (deviation) deviation.DESVfr1_entModulo.focus ()
There is even great, I do my tasks I can open,. Tabs and work on them: Work with tabs My problem is that in the menu bar or in the contextual menu of the right click, when hitting search, call a simple function that does: def search (self, event): self.DESVfr1_entModulo.focus ()
Event CTRL+F, find It is to activate the focus in the entry, when opening each tab and doing CTRL F, or searching in the menu, it manages to activate the focus, the problem is when I return to a previous tab, this no longer works for me, and I have seen that It is because perhaps in each tab, it will be created with a different name to the widget: Tab 1: .! Deviation.! Labelframe.! Entry
Tab 2: .! Deviation2.! Labelframe.! Entry
I think I understand that the last tab is always active. I have seen that there is a lot of talk about link tags, and I think it may be the solution but I don't understand how I can implement it in my case. Thanks  |

| Limiting upload file size, maximum uploads in one request, and file type within the PHP script file itself Posted: 10 Sep 2021 08:00 AM PDT I've been dealing with a small problem that requires me to individually define maximum upload file size, limit maximum uploads in one POST and file types on a per-script basis. This means that I can't use the .htaccess file or php.ini to define max_post_size and other parameters that limit what can be uploaded. The script is just used to upload and store images on a publicly viewable webserver. The upload script works in tandem with ShareX. I eventually want to give access to hosting to a few others, so I want to limit the types that they can upload, how much they can upload in one request, the file size of their images. How would I add these parameters to the script itself instead of using server configurations to limit everyone? Here is the script: <?php $secret_key = "REDACTED"; //32-char $sharexdir = "REDACTED"; $domain_url = "REDACTED"; $lengthofstring = 7; $space= "\x20"; $linkembedu2800 =; function RandomString($length) { $keys = array_merge(range(0,9), range('a', 'z')); $key = ''; for($i=0; $i < $length; $i++) { $key .= $keys[mt_rand(0, count($keys) - 1)]; } return $key; } if(isset($_POST['secret'])) { if($_POST['secret'] == $secret_key) { $filename = RandomString($lengthofstring); $target_file = $_FILES["sharex"]["name"]; $fileType = pathinfo($target_file, PATHINFO_EXTENSION); if (move_uploaded_file($_FILES["sharex"]["tmp_name"], $sharexdir.$filename.'.'.$fileType)) { echo $domain_url.$sharexdir.$filename.'.'.$fileType.$space.$linkembedu2800; } else { echo 'ERROR: INTERNAL SERVER ERROR'; } } else { echo 'ERROR: INVALID SECRET KEY'; } } else { echo 'ERROR: NO POST DATA RECIEVED'; } ?>

EDIT 2 Here is the actual install code of the Install2012R2.ps1 script $updatedir = ".\" $files = Get-ChildItem $updatedir -Recurse $msus = $files | ? {$_.extension -eq ".msu"} $exes = $files | ? {$_.extension -eq ".exe"} foreach ($file in $msus){ $KBCtr++ $fullname = $file.fullname # Need to wrap in quotes as folder path may contain space $fullname = "`"" + $fullname + "`"" $KBN = $fullname.split('-')[1] # Need to wrap in quotes as folder path may contain space $fullname = "`"" + $fullname + "`"" # Specify the command line parameters for wusa.exe $parameters = $fullname + " /quiet /norestart" # Start services and pass in the parameters $install = [System.Diagnostics.Process]::Start( "wusa",$parameters ) $install.WaitForExit() }

| typeahead.js with multiselect extension: how do I set a default selection? Posted: 10 Sep 2021 07:59 AM PDT I have an app with jQuery typeahead and the typeahead multiselect extension. On load I would like certain elements to be selected by default, how do I do that? $(document).ready(function() { waitingDialog.hide(); $("#typeahead").typeaheadmulti({ minLength: 1, hint: false, highlight: true, autocomplete: false, }, { name: 'Typeahead', source: function(query, syncResults, process) { var args = {}; args.Str = query; gers = aj("Search", function(res) { names = []; ids = {}; res.d = JSON.parse(res.d); $.each(res.d, function(i, lkp) { names.push(lkp.name.trim().toUpperCase()); }); process(names); }, JSON.stringify(args), null); }, limit: 10 }) });

| how to initialize string[20] in the constructor? Posted: 10 Sep 2021 07:59 AM PDT in this question , im required to have a string of limit 20 for owner and address. but I'm unable to initialize these two strings in the constructer, hence in the main code, I get an error no default constructor for class House what should i do to avoid this error? class House { private: string owner[20]; string address[20]; int bedrooms; float price; public: House(string owner[20], string address[20], int bedrooms = 0, float price = 0.0) { this->owner[20] = owner[20]; this->address[20] = address[20]; this->bedrooms = bedrooms; this->price = price; } void setOwner(string owner[20]) { this->owner[20] = owner[20]; } void setAddress(string address[20]) { this->address[20] = address[20]; } void setBedrooms(int bedrooms) { this->bedrooms = bedrooms; } void setPrice(float price) { this->price = price; } string getOwner() { return owner[20]; } string getAddress() { return address[20]; } int getBedrooms() { return bedrooms; } float getPrice() { return price; } }; int main() { House* h[100]; House houseinfo; h->houseinfo; return 0; }

| Where is header and payload information about a calloc stored in heap? Posted: 10 Sep 2021 07:59 AM PDT I want to know how this structure & calloc are allocated in heap. I mean how glibc keep information in memory like this is structure this is its data type so on. #include<stdio.h> struct student{ int rollno; char level; }; int main(){ struct student *p = calloc(1,sizeof(struct student)); p->rollno=767; p->level='A'; printf("addr of p is =%p\n",p); printf("student_struct_size=%ld\n",sizeof( }
In my system addr of p is =0x555555756260 (gdb) x/16b 0x555555756260 0x555555756260: -1 2 0 0 65 0 0 0 0x555555756268: 0 0 0 0 0 0 0 0
I can understand why 65 is coming but where is 767, also where is header information about calloc (what is boundary of calloc) If i Do x/16b 0x555555756260-8 i get 33 , is 33 is size of all payload + header information , can u justify why 33 is coming (gdb) x/16b 0x555555756260-8 0x555555756258: 33 0 0 0 0 0 0 0 0x555555756260: -1 2 0 0 65 0 0 0

| How to use TypeScript's indexed access types with nullable types? Posted: 10 Sep 2021 07:59 AM PDT I'm trying to define a TypeScript type in terms of another type. This works: type Result = { data: { nestedData: { foo: string; bar: string } } }; type NestedData = Result['data']['nestedData'];
But, when the data property is nullable, this doesn't work: type Result = { data: { nestedData: { foo: string; bar: string } } | null }; type NestedData = Result['data']['nestedData'];
and results in the error: Property 'nestedData' does not exist on type '{ nestedData: { foo: string; bar: string; }; } | null'.(2339)
How can I define my NestedData type in terms of Result, without duplicating any part of Result's typings? Demo on TypeScript Playground Edit: I'm getting my NestedData type from a codegen tool and I'm defining NestedData as a shorter type alias. In reality the typing is longer so I want to minimize repetition.  |
| How to expand preprocessor variable inside a macro? Posted: 10 Sep 2021 07:59 AM PDT In the header file I have declared a preprocessor variable and I want to create a macro that concatenate it to the name of a function to generate the final function name: #define CLASS_NAME_ONE my_package_name_MyClassName #define FUNCTION_NAME_OF(className, functionName) Java_ ## _ ## className ## _ ## functionName #define FUNCTION_NAME_OF_CLASS_NAME_ONE(functionName) FUNCTION_NAME_OF(CLASS_NAME_ONE, functionName)
... And I use it in the implementation file as follow: jobject FUNCTION_NAME_OF_CLASS_NAME_ONE(functionName)(JNIEnv* jNIEnv, jobject instance, jclass instanceType)
... But the generated code is: jobject Java_CLASS_NAME_ONE_functionName(JNIEnv* jNIEnv, jobject instance, jclass instanceType)
... How can I solve?  |
