[ "It looks like you are trying to serve the codefreeze.html file using the express.static() middleware, but this middleware is not being used correctly.\nThe express.static() middleware is used to serve static files, such as images, CSS, and JavaScript files, from a specified directory. It does not serve HTML files directly, so you will need to use a different approach to serve the codefreeze.html file.\nTo fix this problem, you can use the app.get() method to define a route that will serve the codefreeze.html file when a GET request is sent to the root URL (/). This method takes two arguments: the path of the route (in this case, /) and a callback function that will be called when the route is matched.\nHere's an example of how you can use the app.get() method to serve the codefreeze.html file:\nconst express = require(\"express\");\nconst app = express();\n\napp.listen(3000, () => console.log(\"listening at port 3000!\"));\n\n// Define a route that will serve the codefreeze.html file\napp.get(\"/\", (request, response) => {\n // Use the response.sendFile() method to send the codefreeze.html file\n response.sendFile(__dirname + \"/codefreeze.html\");\n});\n\n", "app.get(\"/\", (req, res) => {\n response.sendFile(*your file path*);\n});\n\nThis should work\n" ]

[ "I think you are missing the sizes tag in there.\n\nsizes defines a set of media conditions (e.g. screen widths) and indicates what image size would be best to choose, when certain media conditions are true.\n\nThe correct way to write the code to achieve would be\n<img src=\"assets/img/software-developer.jpeg\" alt=\"Some Stuff\" sizes=\"(max-width: 449px) 300px, 450px\" srcset=\"assets/img/software-developer-300.jpeg 300w, assets/img/software-developer.jpeg 450w\">\n\nYou can read more about it here\nhttps://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images#how_do_you_create_responsive_images\n", "I figure out the answer by myself. First of all, the srcset tag alone doesn't make too much sense, it must be always used in conjuction with sizes.\nThe srcset tells the browser which imahes are available, for example:\nsrcset=\"assets/img/software-developer-300.jpeg 300w, assets/img/software-developer.jpeg 450w\"\n\nBasically this attributes tells to the browser:\nHey there are two images you can use:\n\nassets/img/software-developer-300.jpeg 300 pixel wide\nassets/img/software-developer.jpeg 450 pixel wide\n\nNow you have to tell the browser to use the former for screen < 450 px and the latter for screen >= 450. You can do this with the attribute sizes:\nsrcset=\"assets/img/software-developer-300.jpeg 300w, assets/img/software-developer.jpeg 450w\" sizes=\"(max-width: 449px) 300px, (min-width: 450px) 450px\"\n\nBasically, for screen up to 449px you can use the 300px image version, for screen starting from 450px you caan use the 450px version. The problem is that there are phone with screen size less than 300px (i.e. Gaalaxy Fold is 280px wide). On these screen the image is cropped and to avoid this you must tell the browser that if the screen size is less than 299px the image must be resized to 100vw. Now in my case, 100vw doesn't work properly so I just reduced it to 75vw.\n" ]

[ "I know this question is old, but I had a similar issue and I stumbled upon this. I wanted to mention how I fixed it for anyone, who is reading it in the future. The problem I had was that Laravel did not allow me to insert a value in a unique column when there was an old record with the same value, but was deleted using soft_delete.\nTo summarize, the goal is to ignore old soft deleted records for a unique column when inserting a new record. The solution I found is in the migration for the table. For example, let us assume we have these columns:\n\ncategory - unique\ndeleted_at - keeps tracks of the deleted rows\n\nBoth should be specified as unique in the migration like so:\n Schema::create('table_name', function (Blueprint $table) {\n $table->string(\"category\");\n $table->softDeletes();\n $table->unique([\"category\", \"deleted_at\"]);\n });\n\nSide note: If you already have the table like I did, you need to change the migration and create the table again (obviously the data will be lost):\n\nRemove the table\nChange the migration\nRemove the record about it from the migrations table\nrun \"php artisan migrate\" to create the table again\n\n" ]

If this operation is done often enough that you care about getting the best possible performance, you could directly use the CUB library which is used by Thrust as backend.

Above command worked for me without any issues.\nWhat follows is an explanation of each part of the command:\n\nfind . -depth -name '*[A-Z]*'\n\nThis will find any file from the current directory (change . to whatever directory you want to process), using a depth-first search (eg., it will list ./foo/bar before ./foo), but only for files that contain an uppercase character. The -name filter only applies to the base file name, not the full path. So this will list ./FOO/BAR but not ./FOO/bar. This is ok, as we don't want to rename ./FOO/bar. We want to rename ./FOO though, but that one is listed later on (this is why -depth is important).\nThis comand in itself is particularly useful to finding the files that you want to rename in the first place. Use this after the complete rename command to search for files that still haven't been replaced because of file name collisions or errors.\n\nsed -n 's/\\(.*\\/\\)\\(.*\\)/mv -n -v -T \\1\\2 \\1\\L\\2/p'\n\nThis part reads the files outputted by find and formats them in a mv command using a regular expression. The -n option stops sed from printing the input, and the p command in the search-and-replace regex outputs the replaced text.\nThe regex itself consists of two captures: the part up until the last / (which is the directory of the file), and the filename itself. The directory is left intact, but the filename is transformed to lowercase. So, if find outputs ./FOO/BAR, it will become mv -n -v -T ./FOO/BAR ./FOO/bar. The -n option of mv makes sure existing lowercase files are not overwritten. The -v option makes mv output every change that it makes (or doesn't make - if ./FOO/bar already exists, it outputs something like ./FOO/BAR -> ./FOO/BAR, noting that no change has been made). The -T is very important here - it treats the target file as a directory. This will make sure that ./FOO/BAR isn't moved into ./FOO/bar if that directory happens to exist.\nUse this together with find to generate a list of commands that will be executed (handy to verify what will be done without actually doing it)\n\nsh\n\nThis pretty self-explanatory. It routes all the generated mv commands to the shell interpreter. You can replace it with bash or any shell of your liking.\n", "Using bash, without rename:\nfind . -exec bash -c 'mv $0 ${0,,}' {} \\;\n\n" ]

I have two classes implementing Runnable, one prints odd sequence and the other prints even. I have an instance of Object, that I use for lock. I initialize the two classes with the same object. There is a synchronized block inside the run method of the two classes, where, inside a loop, each method prints one of the numbers, notifies the other thread, waiting for lock on the same object and then itself waits for the same lock again.\nThe classes : \npublic class PrintEven implements Runnable{\nprivate Object lock;\npublic PrintEven(Object lock) {\n this.lock = lock;\n}\n@Override\npublic void run() {\n synchronized (lock) {\n for (int i = 2; i <= 10; i+=2) {\n System.out.println(\"EVEN:=\"+i);\n lock.notify();\n try {\n //if(i!=10) lock.wait();\n lock.wait(500);\n } catch (InterruptedException e) {\n e.printStackTrace();\n }\n }\n }\n\n }\n}\n\n\npublic class PrintOdd implements Runnable {\nprivate Object lock;\npublic PrintOdd(Object lock) {\n this.lock = lock;\n}\n@Override\npublic void run() {\n synchronized (lock) {\n for (int i = 1; i <= 10; i+=2) {\n System.out.println(\"ODD:=\"+i);\n lock.notify();\n try {\n //if(i!=9) lock.wait();\n lock.wait(500);\n } catch (InterruptedException e) {\n e.printStackTrace();\n }\n }\n }\n}\n}\n\npublic class PrintEvenOdd {\npublic static void main(String[] args){\n Object lock = new Object(); \n Thread thread1 = new Thread(new PrintOdd(lock));\n Thread thread2 = new Thread(new PrintEven(lock));\n thread1.start();\n thread2.start();\n}\n}\n\nThe upper limit in my example is 10.

[ "To implement Elasticsearch search capabilities in ASP.NET, you can use the Elasticsearch.NET and NEST client libraries. These libraries provide a simple and easy-to-use API for working with Elasticsearch from ASP.NET. Here is an example of how you can use the Elasticsearch.NET client library to search a database table in Elasticsearch:\n// create a new Elasticsearch client\nvar elasticClient = new ElasticClient();\n\n// search for documents with a specific field value\nvar searchResponse = elasticClient.Search<YourDocumentType>(s => s\n .Index(\"your-index-name\")\n .Type(\"your-type-name\")\n .Query(q => q\n .Match(m => m\n .Field(\"field-name\")\n .Query(\"field-value\")\n )\n )\n);\n\n// process the search results\nforeach (var hit in searchResponse.Hits)\n{\n Console.WriteLine(hit.Source);\n}\n\nIn this example, we search for documents in the \"your-index-name\" index and \"your-type-name\" type with a \"field-name\" field that has a value of \"field-value\". The search results are returned as a list of IHit objects, where YourDocumentType is the type of the documents being searched.\nFor more information on using Elasticsearch.NET and NEST in ASP.NET, please see the Elasticsearch.NET and NEST documentation:\nElasticsearch.NET:\nhttps://www.elastic.co/guide/en/elasticsearch-net/current/index.html\nNEST:\nhttps://www.elastic.co/guide/en/elasticsearch/client/net-api/current/index.html\n" ]

[ "In terms of performance, it is difficult to compare the two versions directly, as there are many factors that can affect the performance of a Spring Boot application, such as the specific features and dependencies used, the hardware and software environment, and the workload. I haven't found any relevant performance comparisons. However, in general, Spring Boot 3.0 may be better due to several improvements that have been made in the new version.\nSome of the performance improvements in Spring Boot 3.0 include:\n\nThe use of the Eclipse JDT compiler for annotation processing, which\ncan improve build time and memory usage.\nThe use of the Reactor 3.4.0\nlibrary for reactive programming, which can improve the performance\nof reactive applications.\nThe use of the Java 15+ List.of and Map.of\nmethods for creating immutable collections, which can improve the\nperformance of applications that use these collections.\n\nOverall, it is recommended to test the performance of your specific application and compare the results between the two versions to determine which one performs better for your use case. It is possible that the same application will perform better on the older version of Spring Boot.\n" ]

Here is an example:\n @Entity\n@Table(name = \"something\") \npublic class Test {\n @Id\n private Integer id;\n\n private <SomethingHere> customTypeObject;\n\n @JsonValue\n public <SomethingHere> getCustomTypeObject() {\n return customTypeObject;\n }\n\n // Other fields, getters, and setters not shown\n}\n\nWith the @JsonValue annotation, you don't need to manually convert the custom type object to a JSON object in your controller. The Jackson library will automatically use the value returned by the getter method as the JSON representation of the customTypeObject field.\n", "If you want to save a Custom object in the database, then you can create your own Hibernate Convertors\n\nCustom Types\nJPA Converter FYI, But may be out of scope\n\nYou can also try updating the toString() method of your custom object's class.\n\nFrom your question, it is unclear where you want the desired representation, is it in a database or in a Field in UI?\n\n" ]
