"MongoDB - findOne by _id returns null in shell",
"When I run a simple findOne to get a document with no filter, I get this:\n\nmongos> db.mycollection.findOne({},{_id:1})\n{ \"_id\" : \"1d0eb04fd0325cd79e4f8dc24268c6ad2205082199957ce42ffb9e802eec73c9\" }\n\n\nBut when I feed that _id back in as a filter, I get no results:\n\nmongos> db.mycollection.findOne({ \"_id\" : \"1d0eb04fd0325cd79e4f8dc24268c6ad2205082199957ce42ffb9e802eec73c9\" } )\nnull\n\n\nWhy is this? When I search on other fields I am able to get a result, but searching with _id returns nothing.\n\nOf note is that these documents include a nested object with it's own _id. Searching using this nested._id field also returns nothing.\n\nMy environment: 2 shard mongoDB 3.4 running on Centos 7. Each replica set has 3 members and everything looks healthy."

"Converting package using S3 to S4 classes, is there going to be performance drop?",
"I have an R package which currently uses S3 class system, with two different classes and several methods for generic S3 functions like plot, logLik and update (for model formula updating). As my code has become more complex with all the validity checking and if/else structures due to to the fact that there's no inheritance or dispatching based on two arguments in S3, I have started to think of converting my package to S4. But then I started to read about the advantages and and disadvantages of S3 versus S4, and I'm not so sure anymore. I found R-bloggers blog post about efficiency issues in S3 vs S4, and as that was 5 years ago, I tested the same thing now:\n\nlibrary(microbenchmark)\nsetClass(\"MyClass\", representation(x=\"numeric\"))\nmicrobenchmark(structure(list(x=rep(1, 10^7)), class=\"MyS3Class\"),\n new(\"MyClass\", x=rep(1, 10^7)) )\nUnit: milliseconds\n expr\n structure(list(x = rep(1, 10^7)), class = \"MyS3Class\")\n new(\"MyClass\", x = rep(1, 10^7))\n min lq median uq max neval\n 148.75049 152.3811 155.2263 159.8090 323.5678 100\n 75.15198 123.4804 129.6588 131.5031 241.8913 100\n\n\nSo in this simple example, S4 was actually bit faster. Then I read SO question about using S3 vs S4, which was quite much in favor of S3. Especially @joshua-ulrich 's answer made me doubt against S4, as it said that \n\n\n any slot change requires a full object copy\n\n\nThat feels like a big issue if I consider my case where I'm updating my object in every iteration when optimizing log-likelihood of my model. After some googling I found John Chambers post about this issue, which seems to be changing in R 3.0.0.\n\nSo although I feel it would be beneficial to use S4 classes for some clarity in my codes (for example more classes inheriting from the main model class), and for the validity checks etc, I am now wondering is it worth all the work in terms of performance? So, performance wise, is there real performance differences between S3 and S4? Is there some other performance issues I should be considering? Or is it even possible to say something about this issue in general?\n\nEDIT: As @DWin and @g-grothendieck suggested, the above benchmarking doesn't consider the case where the slot of an existing object is altered. So here's another benchmark which is more relevant to the true application (the functions in the example could be get/set functions for some elements in the model, which are altered when maximizing the log-likelihood):\n\nobjS3<-structure(list(x=rep(1, 10^3), z=matrix(0,10,10), y=matrix(0,10,10)),\n class=\"MyS3Class\")\nfnS3<-function(obj,a){\n obj$y<-a\n obj\n}\n\nsetClass(\"MyClass\", representation(x=\"numeric\",z=\"matrix\",y=\"matrix\"))\nobjS4<-new(\"MyClass\", x=rep(1, 10^3),z=matrix(0,10,10),y=matrix(0,10,10))\nfnS4<-function(obj,a){ \n obj@y<-a\n obj\n}\n\na<-matrix(1:100,10,10)\nmicrobenchmark(fnS3(objS3,a),fnS4(objS4,a))\nUnit: microseconds\n expr min lq median uq max neval\n fnS3(objS3, a) 6.531 7.464 7.932 9.331 26.591 100\n fnS4(objS4, a) 21.459 22.393 23.325 23.792 73.708 100\n\n\nThe benchmarks are performed on R 2.15.2, on 64bit Windows 7. So here S4 is clearly slower."

"Implementing KNN with different distance metrics using R",
"I am working on a dataset in order to compare the effect of different distance metrics. I am using the KNN algorithm.\n\nThe KNN algorithm in R uses the Euclidian distance by default. So I wrote my own one. I would like to find the number of correct class label matches between the nearest neighbor and target.\n\nI have prepared the data at first. Then I called the data (wdbc_n), I chose K=1. I have used Euclidian distance as a test.\n\nlibrary(philentropy)\nknn <- function(xmat, k,method){\n n <- nrow(xmat)\n if (n <= k) stop(\"k can not be more than n-1\")\n neigh <- matrix(0, nrow = n, ncol = k)\n for(i in 1:n) {\n ddist<- distance(xmat, method) \n neigh[i, ] <- order(ddist)[2:(k + 1)]\n }\n return(neigh)\n}\nwdbc_nn <-knn(wdbc_n ,1,method=\"euclidean\")\n\n\nHoping to get a similar result to the paper (\"on the surprising behavior of distance metrics in high dimensional space\") (https://bib.dbvis.de/uploadedFiles/155.pdf, page 431, table 3).\n\nMy question is \n\nAm I right or wrong with the codes?\n\nAny suggestions or reference that will guide me will be highly appreciated.\n\nEDIT \n\nMy data (breast-cancer-wisconsin)(wdbc) dimension is \n\n569 32\n\n\nAfter normalizing and removing the id and target column the dimension is \n\ndim(wdbc_n)\n569 30\n\n\nThe train and test split is given by \n\nwdbc_train<-wdbc_n[1:469,]\nwdbc_test<-wdbc_n[470:569,]"

"Why is `TypeError: firebase.initializeApp is not a function` occurring only when @firebase/testing is imported in a submodule to a cypress plugin?",
"I am using Cypress to test an app and using Cypress Tasks to run backend database seeding.\n\nThe backend is a locally emulated Firestore database.\n\nUsually, I am able to run initializeAdminApp() without problems, from my Cypress plugins file. I am using the new built-in TS capabilities of Cypress.\n\nWhen I import @firebase/testing in my plugins/index.ts file, there is no issue at all.\n\nBut if I instead import @myapp/testing which imports @firebase/testing and runs initializeAdminApp(), I get TypeError: firebase.initializeApp is not a function.\n\nSo I was able to fix the issue by simply adding this to my plugins/index.ts file:\n\nimport * as testing from '@firebase/testing';\ntesting;\n\n\nAnd then the rest of the code (that was crashing before with that error) suddenly works fine.\n\nI've even console logged the testing object from my submodule. It shows all the property keys as per normal.\n\nSimply importing it and referencing the imported variable in a pointless expression, makes the function not crash when imported and used in a submodule.\n\nUsing an NX monorepo.
