"How to do recurring code review efficiently in Bitbucket.org?",
"In our company, we are using Bitbucket cloud edition. I'm wondering, do you guys have some ways of making recurring code review (I once did code review, author fixed comments, and then I come back to review again) more pleasant and easy?\n\nRight now, after I'm going back to code review I have several problems:\n\n\nOld comments are accessible only through button \"Outdated comments\" - I'd prefer have every comment in respective place, when I'm reviewing but it can be marked that it is outdated\nComments on removed files are very hard to review, because they are only accessible through Activity tab on the right - someone forgot doing git mv\nI miss button \"Needs more work\" which indicated that I already reviewed this code review and author didn't do any new commits\nLast but not least - why bitbucket is soooo slow???\n\n\nIf you guys have some ideas how to make reviewing code in Bitbucket cloud better, I'd appreciate hearing your tips.\n\nRegards,\nSebastian"

"Client Socket on Java",
"In most Java client/server examles they use ServerSocket.accept() method to receive messages from the client. This method blocks the thread. This looks good becouse server does not do useless work and can answer immediately.

"Is it possible to have a specific polling URL, to get the HttpSession status, but the polling itself should not extend the session?",
"Is it possible to have a specific polling URL, to get the HttpSession status, but the polling itself should not extend the session?\n\nThe idea is that the UI keeps polling the server, and automatically navigates to the logout page once the session has elapsed.\n\nAlso, is it possible to do this with web sockets? Can a HttpSession die while a WebSocket is still active? In that case, I could push the information to the client when the Session dies.\n\nEdit: To be more specific, I would like to know if there is something built-in in JavaEE: If I configure some exception in web.xml so that the a particular URL will be excluded from extending the HttpSession. In case WebSockets being alive doesn't affect the HttpSession, then I can use the open socket to inform the client that the session has ended."

"Is there value for including the [ValidateAntiForgeryToken] attribute on the Login action?",
"I am in the process of learning ASP.NET Core MVC and the book I am reading includes the following code example:\n\n[HttpPost]\n[AllowAnonymous]\n[ValidateAntiForgeryToken]\npublic async Task<IActionResult> Login(LoginModel loginModel) \n{\n // More stuff goes here.\n}\n\n\nYou can see that the author includes the [ValidateAntiForgeryToken] attribute on the action method. As far as my research goes, there does not appear to be any harm on including the attribute but I also not sure there is a benefit.\n\nBased on my understanding on how the [ValidateAntiForgeryToken] works, it looks like all that its achieving here is preventing a malicious website from logging me in... not sure I see the harm on someone trying to do that.\n\nClearly I am missing something , so my question is, what exactly is the use of the [ValidateAntiForgeryToken] trying to prevent in this specific scenario?\n\nThanks."

"Issues with running a consul docker health check",
"am running the progrium/consul container with the gliderlabs/registrator container. I am trying to create health checks to monitor if my docker containers are up or down. However I noticed some very strange activity with with health check I was able to make. Here is the command I used to create the health check:\n\ncurl -v -X PUT http://$CONSUL_IP_ADDR:8500/v1/agent/check/register -d @/home/myUserName/health.json\n\n\nHere is my health.json file:\n\n{\n\"id\": \"docker_stuff\",\n\"name\": \"echo test\",\n\"docker_container_id\": \"4fc5b1296c99\",\n\"shell\": \"/bin/bash\",\n\"script\": \"echo hello\",\n\"interval\": \"2s\"\n}\n\n\nFirst I noticed that this check would automatically delete the service whenever the container was stopped properly, but would do nothing when the container was stopped improperly (i.e. durring a node failure). \n\nSecond I noticed that the docker_container_id did not matter at all, this health check would attach itself to every container running on the consul node it was attached to.\n\nI would like to just have a working tcp or http health test run for every docker container running on a consul node (yes I know my above json file runs a script, I just created that one following the documentation example). I just want consul to be able to tell if a container is stopped or running. I don't want my services to delete themselves when a health check fails. How would I do this. \n\nNote: I find the consul documentation on Agent Health Checks very lacking, vague and inaccurate. So please don't just link to it and tell me to go read it. I am looking for a full explanation on exactly how to set up docker health checks the right way. \n\nUpdate: Here is how to start consul servers with the most current version of the official consul container (right now its the dev versions, soon ill update it with the production versions):\n\n#bootstrap server\ndocker run -d \\\n-p 8300:8300 \\\n-p 8301:8301 \\\n-p 8301:8301/udp \\\n-p 8302:8302 \\\n-p 8302:8302/udp \\\n-p 8400:8400 \\\n-p 8500:8500 \\\n-p 53:53/udp \\\n--name=dev-consul0 consul agent -dev -ui -client 0.0.0.0\n\n#its IP address will then be the IP of the host machine\n#lets say its 172.17.0.2\n\n#start the other two consul servers, without web ui\ndocker run -d --name --name=dev-consul1 \\\n-p 8300:8300 \\\n-p 8301:8301 \\\n-p 8301:8301/udp \\\n-p 8302:8302 \\\n-p 8302:8302/udp \\\n-p 8400:8400 \\\n-p 8500:8500 \\\n-p 53:53/udp \\\nconsul agent -dev -join=172.17.0.2\n\ndocker run -d --name --name=dev-consul2 \\\n-p 8300:8300 \\\n-p 8301:8301 \\\n-p 8301:8301/udp \\\n-p 8302:8302 \\\n-p 8302:8302/udp \\\n-p 8400:8400 \\\n-p 8500:8500 \\\n-p 53:53/udp \\\nconsul agent -dev -join=172.17.0.2\n\n# then heres your clients\ndocker run -d --net=host --name=client0 \\\n-e 'CONSUL_LOCAL_CONFIG={\"leave_on_terminate\": true}' \\\nconsul agent -bind=$(hostname -i) -retry-join=172.17.0.2\n\n\nhttps://hub.docker.com/r/library/consul/"

"Alternative to global static data that's not ASP.NET specific",
"I am working on a legacy system that consists of a WinForms application, a set of XML Web Services, and a set of WCF services. Each application is \"internally\" 3-tier, in that the business and data logic were factored out into separate assemblies, but \"externally\" monolithic, since all 3 assemblies are loaded by each application into their own app domain.\n\nThe WinForms application must have come first, because the internal design is littered with global static data that crosses the tier boundaries. The most glaringly bad of these is the logged-in user information. The front-end is expected to \"log in\" a user immediately, and the data later then uses that information on every database read and write. \n\nThis \"works OK\" in the WinForms app, but not surprisingly falls apart in the web services, because parallel incoming requests stomp over each other's static data and very bad things start to happen. So far I've found a number of options for keeping track of global data at the ASP.NET level but they all rely on ASP.NET specific objects like Session or HttpContext, which I can't use. This needs to work in the WinForms application as well.\n\nAre there any other options that are similar to static variables that I could retrofit into the system (with reasonable effort; refactoring the system to be designed properly is currently out of scope)?"

I know how to make the onChange events work if these were known dropdownlists, but every project I'll be working on is different and I'd like to get this to work without having to retool every time the project requirements change.\n\nFor example, when I call getDropDownLists(['mom','dad','baby'],family), I would get three dropdownlists: familySrcLevel_0,familySrcLevel_1,familySrcLevel_2. How would I then create onClick events for each of these dropdownlists, knowing that I won't always know how many there are? Is such a thing possible? It has to be done in Extendscript."

"Clarification needed with not-equal operator",
"I wrote this program:\n\n#include <iostream>\n\nusing namespace std;\n\nvoid unequalityOperator(){\n\n cout << \"Running unequalityOperator...\" << endl;\n\n bool a = true, b = false;\n\n if ( a != b ) cout << \"!=\" << endl;\n if ( a =! b ) cout << \"=!\" << endl;\n}\n\nint main()\n{\n unequalityOperator();\n\n system(\"pause\");\n return 0;\n}\n\n\nAnd I was surprised that it run and printed both of the strings. So I tried the same thing with some other binary operators like <=, >=, etc. but it didn't work.\nTherefore I would like to understand whether there is a difference between != and =!.\n\nI do know that there are some operators like +=, -=, etc. that work differently and, e.g., the difference between += and =+ is that the addition will occur before or after (respectively) the actual command. And for this reason I suspect that there is difference with the hierarchy in the implementation of these operators, but I am not really sure what. \n\nSo please help me understand."

"sed stripping hex from start of file including pattern",

The problem is that it leaves the 0D0A0D0A, so I have to do a second pass to pick that up.\n\nIs there a way in one command to delete up to and including the pattern that you match to and save it back into the same file ? \n\nthanks in advance.\n\nID"

"Can lego EV3 brick be programmed to get user input?",
"Sorry I am totally new to Lego ev3 Mindstorms, I need to do this for a subject's project.\n\nI am going to program it using ROBOTC language, and to meet my project requirements I am thinking to allow user to enter input to the robot using the EV3 brick. Is it possible to do so? If possible how can I do it? \n\nLastly may I get some online guides to ROBOTC programming for Lego EV3 mindstorms?\n\nSorry for asking so many questions :(\n\nAny help is much appreciated! :)\nThank you very much! :)"

"Populate variables according to column index and other values",
"I have a dataset containing observations of cases. In reality each case is observed at ten different time periods (P1 to P10) and can be in one of 5 states (1 to 5) at each period.\n\nEach case is in state 1 at P1. A case can only progress from state 1 to 2 to 3 etc, and must pass from 1 to 2 before passing to 3 etc. A case does not necessarily change state during the observed period.\n\nIn my dataset I have the states of each case at P1 and P10 and also know in which period the case attained each state (S2 to S5 e.g. a value for S2 of 5 means the first observation of the case in state 2 was in P5).\n\nMy data is thus as follows:\n\n# Create test dataset #\n\ntest <- as.data.frame(c(1:8))\nnames(test) <- \"Obs\"\n\ntest$P1 <- 1\nfor (i in 2:9){\n test[[paste(\"P\",i,sep=\"\")]] <- NA\n}\ntest$P10 <- c(1,5,3,2,2,5,5,4)\n\ntest$S2 <- c(NA,2,4,9,7,3,3,2)\ntest$S3 <- c(NA,5,8,NA,NA,4,4,3)\ntest$S4 <- c(NA,7,NA,NA,NA,5,8,5)\ntest$S5 <- c(NA,9,NA,NA,NA,10,9,NA)\n\n\nI would like to recreate the sequence of observations P2 to P9 for each case, fill in the blanks so to speak. I tried the following:\n\nfunc <- function(base){\n for(i in 1:nrow(base)){\n if (is.na(base$S5[i])) {\n for (j in 2:9){\n base[[paste(\"P\", j, sep=\"\")]] <- NA\n }\n }\n else {\n for (j in 2:base$S5[i]){\n base[[paste(\"P\", j, sep=\"\")]] <- 5\n }\n }\n }\n base\n}\n\ntest <- func(test)\n\n\nI would like to populate all Pi columns where i <= the value of S5 with 5. Then do the same for S4, S3 and S2. The desired result being :\n\n Obs P1 P2 P3 P4 P5 P6 P7 P8 P9 P10 S2 S3 S4 S5\n1 1 1 1 1 1 1 1 1 1 1 1 NA NA NA NA\n2 2 1 2 2 2 3 3 4 4 5 5 2 5 7 9\n3 3 1 1 1 2 2 2 2 3 3 3 4 8 NA NA\n4 4 1 1 1 1 1 1 1 1 2 2 9 NA NA NA\n5 5 1 1 1 1 1 1 2 2 2 2 7 NA NA NA\n6 6 1 1 2 3 4 4 4 4 4 5 3 4 5 10\n7 7 1 1 1 2 3 3 3 4 5 5 4 5 8 9\n8 8 1 2 3 3 4 4 4 4 4 5 2 3 5 NA\n\n\nAs an addition, once the final transition has occurred for a case, I would like all following values to be the dummy value 9:\n\n Obs P1 P2 P3 P4 P5 P6 P7 P8 P9 P10 S2 S3 S4 S5\n1 1 1 9 9 9 9 9 9 9 9 9 NA NA NA NA\n2 2 1 2 2 2 3 3 4 4 5 9 2 5 7 9\n3 3 1 1 1 2 2 2 2 3 9 9 4 8 NA NA\n4 4 1 1 1 1 1 1 1 1 2 9 9 NA NA NA\n5 5 1 1 1 1 1 1 2 9 9 9 7 NA NA NA\n6 6 1 1 2 3 4 9 9 9 9 5 3 4 5 10\n7 7 1 1 1 2 3 3 3 4 5 9 4 5 8 9\n8 8 1 2 3 3 4 4 4 4 4 5 2 3 5 NA\n\n\nFor this last part I could use :\n\nfor(i in 1:nrow(test)){ \n test$last_chg[i] <- ifelse(is.na(test$S2[i]),NA,max(test[i,c(12:15)], na.rm=T))\n}\n\n\nto obtain the column index of the last state change, but how would I populate all columns to the right of this with 9?"
