"ASP.NET Handler for managing images/files",
"I need to do the following:\n\n\nShow Image on a page\nShow a link to a document (PDF, DOC etc) that opens up the document\nUpload a image\n\n\nI have the functionality in the backend that has the following signatures:\n\npublic byte[] GetFile(string fileName) //For both documents and images\n\npublic void AddFile(string fileName, byte[] data) //For both documents and images\n\n\nMy question is, can I write a handler that can get images/documents and upload images/documents so that I can use it in my client by doing a:\n\n<asp:Image runat=\"server\" ImageUrl=\"~/Image.ashx?FileName=myFileName\" />\n\n\nThe handler in turn would call the GetFile and AddFile methods.\n\nThis may work for showing images. What about showing documents and uploading images/documents?\n\nAlso, what about the security associated with the handler? Can a malicious user use it?"

It searches for two neighbor types - cardinal and principal. Or, 4 and 8. Each set is placed in a 2D array. I can then grab the neighbors of a coordinate by doing something like cardinal_array[0, 0] which will return a set of coordinates. I hope that makes sense! I use neighbors a TON in my project so it's faster to find and store them all once rather than repeatedly look them up. Enormous parts of my engine use these neighbor sets so I'd rather speed up how it currently works than making any major changes. The sets are comprised of tuples containing the (x, y) coordinates of each neighbor. The tuple thing can be changed if you have a better solution. This function is called once during map generation and its the slowest by far."

"Resolving NodeJS CSS subpackages?",
"I'm creating a CSS library and I'd like to support subpackages the same way RxJS does. For example with RxJS we can import the entire kitchen sink like this (Taken from https://www.npmjs.com/package/rxjs):\n\nvar Rx = require('rxjs/Rx'); \nRx.Observable.of(1,2,3); // etc\n\n\nOr individual operators like this:\n\nvar Observable = require('rxjs/Observable').Observable;\n// patch Observable with appropriate methods\nrequire('rxjs/add/observable/of');\nrequire('rxjs/add/operator/map');\n\n\nMy initial observation is that this may be as simple as just packaging the modules in subfolders of the root module. For example RxJS node_modules install folder has the subfolder rxjs/add/observable which contains all the observable extensions like zip.js, throw.js..., etc.\n\nSo following this pattern postcss-import could be extended to resolve imports in submodule folders the same way. For example:\n\n\n@import @superflycss/utilities-layout/margins\n\n\nWould import node_modules/superflycss/utilities-layout/margins.css and if that does not exist it would look for node_modules/superflycss/utilities-layout/margins/index.css, and if that does not it exist it would thrown an error.\n\n\n@import @superflycss/utilities-layout/margins/\n\n\nWould import node_modules/superflycss/utilities-layout/margins/index.css only.\n\nThe modules I'm producing have have the kitchen sink packaged in the directory target/main/css/index.css. This exposes all the css utilities or components (Depending on what type of module it is).\n\nThe problem is, as with RxJS, this can be a very heavy file (For instance contain imports to all Google Fonts). \n\nSo I'm hoping that by following the RxJS approach the entire thing becomes more flexible and standardized by following the same rules that NodeJS require.resolv() algorithm uses.

"Searching XCode for strings starting with _",
"I read: \nRegular Expression to match string starting with "stop"\n\nI want to search for all strings starting with a _ character using regex search in XCode (in case that matters) which I initially thought I would be able to search for with ^_ but that only returns me lines that start with _ they exclude lines with spaces.\n\nI would like my search to return all of the following:\n\n_foo\n _bar\n _baz\n\n\nfor example and exclude things like\n\nfoo_bar \n#_\n wholeWord_anotherWord\n\n\nor any other string that doesnt start with '_' followed by myString (ex _myString is a desired result). Basically I'm looking for all variables following the _ naming convention.\n\nI read: How to ignore whitespace in a regular expression subject string?\n\nI tried \"\\s*^_\" but that returned me only 'new line'_aString. Did I misunderstand the solution? What will give me the correct response of any _variable?"

"Deal with standard library types in scope of dependency injection",

The type is already tested by Microsoft.\nHowever it breaks incapsulation and maybe ISP from SOLID.

"How should I update multiple RavenDB documents from a daily feed?",
"I'm using RavenDB to hold several thousand documents. The data comes from a daily xml feed which I'll update by running a C# console app. Below is the code that processes the feed to keep the database in sync with any changes. I've had quite a few problems with this so I'm wondering if I've picked the wrong strategy. Here are some important things to note.\n\n\nNew items may have been added to the feed and existing items may\nhave changed, so each time it runs I want to either add or update a\ndocument depending on whether or not it's new.\nThe xml feed doesn't contain any reference to my RavenDB IDs, only its internal key for each item. So when retrieving an existing\ndocument to update I can only do that by examining the \"SourceID\"\nproperty on the document.\nI'm using \"take\" to only work with 500 docs at a time partly because my db is limited to 1000 docs, and partly because without\nTake() I seem to be only able to retrieve 128 docs.\nAs it stands, this code falls over with a \"can't do more than 30 updates in a session\" error, I think because each time I try to\nretrieve an existing record from dbItems it actually hits the\ndatabase again.\nI can fix the issue at (4) above by calling ToList() on items, but if I do that the existing item doesn't get updated when I call\nsession.SaveChanges() (I'm imagining this like a disconnected\nrecordset).\n\n\nCan anyone give me some pointers?\n\n public void ProcessFeed(string rawXml)\n {\n XDocument doc = XDocument.Parse(rawXml);\n var items = ExtractItemsFromFeed(doc).OrderBy(x => x.SourceId).Take(500);\n using (IDocumentSession session = _store.OpenSession())\n {\n var dbItems = session.Query<AccItem>().OrderBy(x => x.SourceId).Take(500);\n foreach (var item in items)\n {\n var existingRecord = dbItems.SingleOrDefault(x => x.SourceId == item.SourceId);\n if (existingRecord == null)\n {\n session.Store(item);\n _logger.Info(\"Saved new item {0}.\", item.ShortName);\n }\n else\n {\n // update just one field for now\n existingRecord.Village = item.Village;\n _logger.Info(\"Updated item {0}.\", item.ShortName);\n }\n }\n session.SaveChanges();\n } \n }"

"How to stop CORB from blocking requests to data resources that respond with CORS headers?",
"I am developing a Chrome extension which makes requests from certain websites to an API I control. Until Chrome 73, the extension worked correctly. After upgrading to Chrome 73, I started getting the following error:\n\n\n Cross-Origin Read Blocking (CORB) blocked cross origin response\n http://localhost:3000/api/users/1 with MIME type application/json\n\n\nAccording to Chrome's documentation on CORB, CORB will block the response of a request if all of the following are true:\n\n\nThe resource is a \"data resource\". Specifically, the content type is HTML, XML, JSON\nThe server responds with an X-Content-Type-Options: nosniff header, or if this header is omitted, Chrome detects the content type is one of HTML, XML, or JSON from inspecting the file\nCORS does not explicitly allow access to the resource\n\n\nAlso, according to \"Lessons from Spectre and Meltdown\" (Google I/O 2018), it seems like it may be important to add mode: cors to fetch invocations, i.e., fetch(url, { mode: 'cors' }). \n\nTo try to fix this, I made the following changes:\n\nFirst, I added the following headers to all responses from my API:\n\nAccess-Control-Allow-Credentials: true\nAccess-Control-Allow-Headers: Content-Type\nAccess-Control-Allow-Methods: GET, POST\nAccess-Control-Allow-Origin: https://www.example.com\n\n\nSecond, I updated my fetch() invocation on the extension to look like this:\n\nfetch(url, { credentials: 'include', mode: 'cors' })\n\n\nHowever, these changes didn't work. What can I change to make my request not be blocked by CORB?"
