"Create-react-app SASS source maps not working",
"SASS source map fails to output on create-react-app 2 (reported bug), been trying to find a workaround to this while an official fix is being considered.\n\nAnother user suggested adding the below to scripts: \n\n\"scripts\": {\n \"build-css\": \"node-sass --source-map true --include-path ./src --include-path ./node_modules src/assets/sass -o public/css\",\n \"watch-css\": \"npm run build-css && node-sass --source-map true --include-path ./src --include-path ./node_modules src/assets/sass -o public/css --watch --recursive\"\n\n\nThis does the trick but generating another CSS which would get picked up outside of webpack, also breaking CSS injection (hot loading).\n\nThis is how the CSS is being included (via import on the index.js file). Ideally this should remain as is.\n\nimport \"styles/main.scss\";\n\n\nBelow the package.json (react-scripts v2.1.1):\n\n\"scripts\": {\n \"start\": \"react-scripts start\",\n \"build\": \"react-scripts build\",\n \"test\": \"react-scripts test\",\n \"lint\": \"NODE_ENV=production eslint src --ext '.js,.jsx'\",\n \"lint-fix\": \"yarn lint --fix\",\n \"lint-check\": \"NODE_ENV=production eslint --print-config . | eslint-config-prettier-check\",\n \"prepare-mobile\": \"node prepare-mobile.js\",\n \"release-mobile\": \"node prepare-mobile-release.js\",\n \"postbuild\": \"yarn prepare-mobile\",\n \"precommit\": \"pretty-quick --staged\"\n }\n\n\nIs there any way to output the SASS source map other than the above approach and without having to eject webpack?"

"Avoid download popup in Internet Explorer when loading file with new format in Rails",
"In my rails app, I've defined a new format called 'extension'. My extension format is responsible for rendering views for an external web browser extension that I've developed. So I can call\n\n/messages/new.extension\n\nand have code specific to my web browser extension rendered.\n\nThis strategy works great until IE comes into play. On any IE version before 9, the browser doesn't know what to do with .extension files, and so IE defaults to a download popup like so:\n\n\n\nAny thoughts on how avoid this download popup? Is there maybe another format I can use instead?"

"How to read all the records in a Kafka topic",
"I am using kafka : kafka_2.12-2.1.0, spring kafka on client side and have got stuck with an issue.\n\nI need to load an in-memory map by reading all the existing messages within a kafka topic. I did this by starting a new consumer (with a unique consumer group id and setting the offset to earliest). Then I iterate over the consumer (poll method) to get all messages and stop when the consumer records become empty.\n\nBut I noticed that, when I start polling, the first few iterations return consumer records as empty and then it starts returning the actual records. Now this breaks my logic as our code thinks there are no records in the topic.\n\nI have tried few other ways (like using offsets number) but haven't been able to come up with any solution, apart from keeping another record somewhere which tells me how many messages there are in the topic which needs to be read before I stop.\n\nAny idea's please ?"

In case of view we have sp_refreshview, do we have any such in functions as well. \n\nFor Ex: \n\nCREATE function [dbo].[Value](@Code varchar(15))\nreturns table\nreturn (\n select top 1 *\n from table with (nolock)\n where Code = @Code order by Date desc\n)\n\n\nNow the table has been modified to have a new column. But the function is not reflecting that value."

It's been a while since I used R, so I looked around on the web, including the CRAN HPC, to see what was available. I think a foreach loop and the bigmemory package will be applicable. I came across this post: Is there a package for parallel matrix inversion in R that had some interesting suggestions. I was wondering if anyone has experience with the HIPLAR packages. Looks like hiparlm adds functionality to the matrix package and hiplarb add new functions altogether. Which of these would be recommended for my application? Furthermore, there is a reference to the PLASMA library. Is this of any help? My matrices have a lot of zeros, so I think they could be considered sparse. I didn't see any examples of how to pass data fro R to PLASMA, and looking at the PLASMA docs, it says it does not support sparse matrices, so I'm thinking that I don't need this library. Am I on the right track here? Any suggestions on other approaches?\n\nEDIT: It looks like HIPLAR and package pbdr will not be helpful. I'm leaning more toward bigmemory, although it looks like I/O may be a problem: http://files.meetup.com/1781511/bigmemoryRandLinearAlgebra_BryanLewis.pdf. This article talks about a package vam for virtual associative matrices, but it must be proprietary. Would package ff be of any help here? My R skills are just not current enough to know what direction to pursue. Pretty sure I can read this using bigmemory, but not sure the processing will be very fast."

The error is that the id-attribut from the submit button of the \"ajax_login.ctp\" is another one than in the javascript codeblock.

My initial idea was something like:\n\nDependencyConfig.ts:\n\nimport { Container } from \"inversify\";\nimport \"reflect-metadata\";\nimport Warrior from \"./interfaces/Warrior\";\nimport { Ninja } from \"./models/Warrior\";\n\nlet container = new Container();\n\ncontainer.bind<Warrior>(Symbol(\"Warrior\")).to(Ninja);\n\nexport default container;\n\n\nApp.ts:\n\nimport container from \"./DependencyConfig\";\n\n@Component({\n name: \"App\",\n provide: container\n})\nexport default class App extends Vue {\n}\n\n\nWhen I checked in my browser's dev console, I was able to see the container has been set to the _provided field. Here's Hello.ts, the child component of App.ts:\n\nHello.ts:\n\n@Component({\n name: \"Hello\",\n inject: [ \"container\" ]\n})\nexport default class Hello extends Vue {\n created (): void {\n console.log(this);\n }\n}\n\n\nAs App.ts could access to Hello.ts through vue-router, it didn't register Hello.ts as a child component. I was expecting the injected container should appear on _injected or something similar. However, I couldn't find it. I changed the inject property value from \"container\" to { \"container\": Symbol(\"Container\") } but I couldn't still find it.\n\nService Locator:\n\nIt works fine to use a service locator instead of the provide/inject pair:\n\n// App.ts\n@Component({\n name: \"App\"\n})\nexport default class App extends Vue {\n}\n\n// Hello.ts\nimport container from \"./DependencyConfig\";\n\n@Component({\n name: \"Hello\"\n})\nexport default class Hello extends Vue {\n created (): void {\n var ninja = container.get<Ninja>(Symbol(\"Warrior\"));\n console.log(ninja.name);\n }\n}\n\n\nHowever, I want to avoid using the service locator pattern here. Did I miss something while using the provide/inject pair for dependency injection?"

"Create DTO with reference to domain object in NHibernate",
"I'm writing a summary query with grouping and counting in my NHibernate 3.3.3.4000 project. I have domain objects Position and Tag, with a many-to-many relationship. One Position will have a handful of Tags, but over time there will be a large number of Positions for each tag. So the relationship is one-directional, where Position has a collection of Tags, but not vice-versa.\n\nMy query will count up the number of Positions with each Tag, for Positions connected to a certain AcademicTerm (a scalar reference in Position). The query below works:\n\n public IPartialResult<TagSummary> GetTagSummaries(string termCode, int skip, int take)\n {\n Tag tagAlias = null;\n AcademicTerm termAlias = null;\n TagSummary summary = null;\n\n var tagQuery = Session.QueryOver<Position>()\n .JoinAlias(p => p.Term, () => termAlias)\n .Where(() => termAlias.TermCode == termCode)\n .JoinQueryOver<Tag>(t => t.Tags, () => tagAlias)\n .SelectList(projections => projections\n .SelectGroup(p => tagAlias).WithAlias(() => summary.Tag)\n .SelectCount(p => p.ID).WithAlias(() => summary.PositionCount)) \n .TransformUsing(Transformers.AliasToBean<TagSummary>());\n\n var countQuery = tagQuery.ToRowCountQuery().FutureValue<int>();\n\n var resultQuery = tagQuery\n .OrderBy(t => t.Name).Asc\n .Skip(skip)\n .Take(take)\n .Future<TagSummary>();\n\n return new PartialResult<TagSummary>(resultQuery, countQuery.Value);\n\n\nThe result type is TagSummary:\n\npublic class TagSummary\n{\n public string TagName { get; set; }\n public int PositionCount { get; set; }\n}\n\n\nWhat's in there is the Tag's Name property, but what I really want is the Tag itself. I can't figure out how to do that. I've got the tagAlias right there, but I don't know how to get it into my TagSummary. Do I have to select each individual property of Tag? I could select the Tag's ID value, and then perform another query, but that doesn't seem very good.\n\nUpdate\nI just discovered that the count query won't work, because ToRowCountQuery will strip out the grouping. Now I'm trying to solve that one."

"Hi I have got a jsFiddle to share but never used it before so I hope I did it right..\nhttp://jsfiddle.net/Mayron/3V62C/\n\nI also have these screen shot to better show what I mean:\nhttp://i.imgur.com/NgQk5P2.jpg\n\nI have a table of images in the gallery page and when you click on an image it opens up a frame that shows a blank but much larger image which gains the source of the smaller image you clicked on. That works fine but I have all the images in the gallery listed in an array and the large frame has three buttons on it: previous, close and next. So far the JavaScript code allows you to click next and previous to go through them but it always begins the journey from array[0] and that is no good if you click to view the 6th one in the list from the gallery page first for example. \n\nI hope that makes sense if not then let me know!\n\nThe issue is with this line that causes it to begin from the first image:\n\ncurrentIndex = 0;\n\n\nHow can I change this so that the currentIndex number is the image that the user first clicks on?"
