Reload signal for UWSGI when using Supervisord?

I have been using UWSGI behind Nginx and I've set supervisord to restart the Nginx and UWSGI instances in case of a server reboot. I am debugging my application and sometimes need to reload the application. According to this page I should be sending SIGHUP in order to do a graceful reload. I could find a stopsignal config setting on this page, but I couldn't find any entry related to something like "reloadsignal" or "restartsignal". Any ideas?

SSH connection problem - allowed from LAN but not WAN

- by Kerem Ulutas

I tried to setup my Arch Linux installation to be an SSH host, but here is the thing: I can ssh localhost, it fails to login via public key and asks for username and password, but still able to login. When I try ssh my_wan_ip it gives ssh_exchange_identification: Connection closed by remote host error. I've read all topics about this error and none helped me. By the way, just confirmed, it gives ssh: connect to host my_dyndns_hostname port 22: Connection refused from another machine (outside of my network, it has different wan ip). I have sshd: ALL in "hosts.allow", ALL:ALL in "hosts.deny". I am able to connect to my own pc via ssh, ping my own pc, but my ssh setup seems to be the problem, it gives that annoying error when I try to ssh from wan. /etc/ssh/ssh_config /etc/ssh/sshd_config And finally, here is the debug output for both sshd and ssh: (i ran ssh command and i took output to sshd debug after that): sshd debug ssh debug I can edit my question according to your needs. Just ask for any more information needed. BTW I have no iptables running. I have one cable dsl modem connected to a asus wl-330gE wireless access point, they both have their firewall disabled. I configured NAT so port 22 is directed to the pc I'm having this trouble. Any help appreciated, thanks..

I am getting an error when trying to use melt() on a dataframe containing Dates

- by Dan

I'd like to melt the dataframe so that in one column i have dates in a second i have username as the variable and finally the value. I'm getting this error: Error in as.Date.numeric(value) : 'origin' must be supplied and while I understand the error I'm not exactly sure how to get around it. A small sample of the data is: structure(list(created_at = structure(c(14007, 14008, 14009, 14010, 14011, 14012), class = "Date"), benjamin = c(16, 0, 0, 0, 0, 0), byron = c(0, 0, 0, 0, 0, 0), cameronc = c(0, 0, 0, 0, 0, 0), daniel = c(0, 0, 0, 0, 0, 0), djdiaz = c(0, 0, 0, 0, 0, 0), gene = c(16, 77, 64, 38, 72, 36), joel = c(0, 0, 0, 0, 0, 2), kerem = c(0, 0, 0, 0, 0, 0), sophia = c(0, 0, 0, 0, 0, 0), SuperMoonMan = c(0, 0, 0, 0, 0, 0)), .Names = c("created_at", "benjamin", "byron", "cameronc", "daniel", "djdiaz", "gene", "joel", "kerem", "sophia", "SuperMoonMan"), row.names = c(NA, 6L), class = c("cast_df", "data.frame")) Thanks for your help.

How to implement dynamic queries for MNesia?

- by Kerem

I'm trying to implement a function that generates dynamic queries for MNesia. For example, when function is called with these arguments; dyn_query(list, person, [name, age], ["jack", 21]) I want to query MNesia to list items whose name is "jack" and age is 21 in person table. I've tried to implement this by using qlc:q(ListComprehension) and qlc:string_to_handle("ListComprehension"). First failed because of compile errors, compiler didn't let me to use functions instead of ListComprehentions and variables instead of record names like "Item#Table.Member". Second failed, because erl_eval couldn't handle records and throwed exceptions like {undefined_record, person}. Which method should I use? How could i solve these problems? Or should I use a different method? Thanks.
