"What does podman run --expose do?",
"I'm new to containers, I don't know Docker, and I'm learning Podman on RHEL. I'm trying to understand what podman run --expose does. All podman-run(1) says for the --expose option is "Expose a port, or a range of ports (e.g. --expose=3300-3310) to set up port redirection on the host system." As I understand/guess it, port redirection is to have an application configured to listen at some port, but have the system expose some other port, and redirect connections to that other to the configured one. In this case, the application would be the container running instance (right?). Edit 2: That's what the --publish option does.\nThere's this article that expands on Docker documentation on the expose directive in the dockerfile, and says that "The EXPOSE instruction exposes the specified port and makes it available only for inter-container communication." which doesn't sound equivalent to my reasoning above.\nCan anybody please explain what exactly $ podman run --expose=4321 imaginedimage does and how to check that it does what's expected to do.\nEdit\n...thinking about it again, I shouldn't expect to see that "exposed" port on $ ss -a\nI'd better ask for an example of "port redirection on the host system" using --expose."

"Is there a proper way of ensuring only one user at a time makes changes to an object with REST+HTTP?",
"I've created a Django/Tastypie application where multiple people could possibly be changing attributes of a row in the database at the exact same time or possibly PUT data which is stale.\n\nFor instance:\n\n # the Django model\n class Thing(models.Model):\n name = models.CharField(max_length=100)\n description = models.TextField()\n\n # the Tastypie Resource\n class ThingResource(ModelResource):\n class Meta:\n queryset = Thing.objects.all()\n\n\nNow let's say any number of users could change the name or description of the Thing at any point in time. They could do it at the same time, or someone could leave the application open for a long time and come back and change it then.\n\nWhat I'm trying to avoid is latent changes that are incorrect. Given the following situation:\n\n#1 User 1: Opens app viewing Thing #1 with name = \"my name\", description = \"my description\"\n#2 User 2: Opens app viewing Thing #1 (same state as User 1)\n#3 User 2: Changes description of Thing #1 to \"something\"\n#4 User 1: Changes name of Thing #1 to \"some other name\"\n\n\nAfter line #4, the state of Thing #1 should be name = \"some other name\", description = \"something\" instead of name = \"some other name\", description = \"my description\".\n\nAssuming the application does not know (in real time or via regularly updating the data on the page) ahead of time that the object on the server has changed, how can this situation be prevented?\n\nI've considered adding a field sequence = models.PositiveIntegerField() in which I increment it every time an update is made and so I can tell if the object is out of date when the update happens, but is that the best way?

I'm stuck at designing a crawler for the www.owler.com website, as it requires login through mail, when we try to access information about company.\n\nEach time we login we'll get a new login token on email that will expire after some time. So, is there any proper solution to preserve the login session on the browser session using Selenium with Py-bindings?\n\nI'm just looking for guidelines to handle these type of situation.

If middleware is the go here, should the middleware be dispatching some kind of SET_STATE action, or is it free to update state right there in the middleware?\n\nEDIT\n\nExperimented with some middleware, such as:\n\nimport { lowerCase, snakeCase } from 'lodash';\nimport * as types from '../constants/ActionTypes';\n\n export default store => next => action => {\n if(action.type == types.COURSES_LOADED) {\n action.courses = action.courses.map((course) => {\n course.additionalProperty = snakeCase(lowerCase(`${course.code} ${course.name}`));\n return course;\n });\n }\n return next(action);\n }\n\n\nIt seems to work fine - is this indeed the intention of middleware?

I've read the man page for alarm() and it doesn't seem as though calling it multiple times with the same value should trip SIGALRM so I'm assuming Lighttpd is sending an alarm signal.\n\nThe big question! Is there a way to run a method after a specific interval, and have that interval be resettable without SIGALRM? I'd be nice if I could have multiple alarms as well.\n\nHere's the whole app thus far:\n\n#include <stdlib.h>\n#include <stdarg.h>\n#include <signal.h>\n#include \"fcgiapp.h\"\n\nFCGX_Stream *in, *out, *err;\nFCGX_ParamArray envp;\nint calls = 0;\n\nvoid print(char*, ...);\nvoid close();\n\nint main(void)\n{\n // If I'm not used for five minutes, leave\n signal(SIGALRM, close);\n\n int reqCount = 0;\n\n while (FCGX_Accept(&in, &out, &err, &envp) >= 0)\n {\n print(\"Content-type: text/plain\\r\\n\\r\\n\");\n\n int i = 0;\n char **elements = envp;\n print(\"Environment:\\n\");\n while (elements[i])\n print(\"\\t%s\\n\", elements[i++]);\n\n print(\"\\n\\nDone. Have served %d requests\", ++reqCount);\n print(\"\\nFor some reason, close was called %d times\", calls);\n\n alarm(300);\n }\n\n return 0;\n}\n\nvoid print(char *strFormat, ...)\n{\n va_list args;\n va_start(args, strFormat);\n FCGX_VFPrintF(out, strFormat, args);\n va_end(args);\n}\n\nvoid close()\n{\n calls++;\n// exit(0);\n}"

Ideally I would like to show the Orchard error page.\n\nFYI I notice that the GET LogOn action (AccountController) does not have a ValidateInput attribute but the POST action does.\n\nPotential Solution:\n\nI set the customErrors element in the web.config to have the attribute defaultRedirect=\"Error.html\" where Error.html is a new file. This of course does not meet my original goal of displaying the Orchard error page.\n\nThis does not seem right as modifying the Orchard core (even though it's just the web.config) does not feel right, especially when thinking ahead to updating the Orchard version by pulling the latest Orchard code from the GitHub repository."
