## My root domain is not resolving to my server, but the www. subdomain works fine

I have the DNS configured like this:

So, my domain example.mx is working as http://www.example.mx. With www there is no problem, but with non-www like http://example.mx it’s not working.

As you can see, my DNS records are pointing in example.mx record to the NS ns1.example.mx. Actually, ns1.example.mx is pointing to my server’s IP.

What could be the problem which is causing http://example.mx not to work while http://www.example.mx does work?

## Unity not resolving android dependencies and only returns resolution success

I just added some android plugins like in app purchase and advertisement and game analytics.

As i remember in previous installations unity downloaded many libraries for plugins on resolve. Now it only returns “resolution success” with no library added and it doeant work in final build.

Can any one tell what is the problem??

## people picker not resolving names correctly

We have our sharepoint server in a domain named DMZ. Our AD users are in another domain, say domain ACME. In the DMZ domain we also have external SP users. All of a sudden the people picker will resolve the DMZ names properly but not the ACME names.

If I open the people picker user search, only DMZ users show up. I have also verified there is still trust between the servers/domains

Any help is appreciated!

## Resolving windows 7 resume

I have a windows 7 desktop. Today when I tried to start it. A black screen appeared. With option

1) continue with resume data 2)delete restoration data and proceed to system boot menu

But the keyboard and mouse is not working

I tried myself with this methods 1) removed the motherboard battery and put it again. And a screen appeared to bios setup. I tried all options. But when the PC rebooted. The same screen appeared

I have read in posts that it is because of corrupted  hiberfil.sys file. Now my question is if I use my hard disk enclosure and use my current hard disk as an external hard disk on an another computer. And from there I delete the  hiberfil.sys file. 1) will it delete all the files on my harddisk And 2) will I be able to boot my PC when I put it in previous pc

## Resolving a system of linear inequalities

How can I solve (by hand) the system of inequalities \begin{align} a+10b+c&\leq 0\ a+15b+4c&\geq 0\ a+12b+c&\geq 0\ a+9b&\geq 0 \end{align} most efficiently?

## Summary

I can only resolve hostnames from and for the default namespace. Requests from and for other namespaces, like kube-system, return NXDOMAIN from coredns. Is there some authorisation that needs to be done?

## Details

I have set up a learning cluster by following Kubernetes the Hard Way except using VirtualBox instead of GCP. All else appears to work except DNS queries in non-default namespaces. More concretely:

• Works (run from default namespace): kubernetes.default
• Does Not work (run from kube-system namespace, get NXDOMAIN): kubernetes.kube-system

### Configuration

I have upgraded to Coredns 1.12 because 1.2.2 failed to resolve anything around 50% of the time. With 1.12 requests resolve 100% of the time (if in the default namespace).

I had to edit the config (in the configmap) by removing the “loop” and “proxy” (replace proxy with forward) plugins to get it working. My config is as follows:

    .:53 {         forward . 192.168.99.254:53 # dnsmasq on host machine         log         errors         health         kubernetes cluster.local in-addr.arpa ip6.arpa {           pods insecure           upstream           fallthrough in-addr.arpa ip6.arpa         }         prometheus :9153         cache 30         reload         loadbalance 

### Troubleshooting

Following this guide I see:

The pods are running OK

$kubectl get pods --namespace=kube-system -l k8s-app=kube-dns NAME READY STATUS RESTARTS AGE coredns-6f8fb48d88-dz9cd 1/1 Running 0 14m coredns-6f8fb48d88-s5rvp 1/1 Running 0 14m  Checking the console I see healthy logging 2019-05-24T04:41:13.990Z [INFO] plugin/reload: Running configuration MD5 = 7c717fabd578b2514cf60fee426fabc6 2019-05-24T04:41:13.992Z [INFO] CoreDNS-1.5.0 2019-05-24T04:41:13.992Z [INFO] linux/amd64, go1.12.2, e3f9a80  The DNS service is available: $   kubectl get svc --namespace=kube-system NAME             TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE kube-dns         ClusterIP   10.32.0.10   <none>        53/UDP,53/TCP   18d 

The endpoints are exposed:

\$   kubectl get ep kube-dns --namespace=kube-system NAME       ENDPOINTS                                                     AGE kube-dns   10.200.21.33:53,10.200.22.17:53,10.200.21.33:53 + 1 more...   18d 

As mentioned above, DNS works but only from the default namespace.

## Explicit, small resolving sets for Hamming graphs

Definition. Let $$G = (V;E)$$ be a finite, undirected graph. $$R = \{r_1, \ldots, r_k \} \subseteq V$$. $$R$$ resolves $$G$$ if $$V \to [0, \infty]^k, v \mapsto (d_G(v,r_1), \ldots, d_G(v, r_k))$$ is injective (where $$d_G$$ is the graph metric associated to $$G$$).

The metric dimension of $$G$$ is the cardinality of the smallest resolving $$R \subseteq V$$.

Definition. Let $$d,q \in \mathbb N$$. The Hamming graph $$H(d,q)$$ is the graph with vertex set $$\{1, \ldots, q\}^d$$ in which two vertices $$u = (u_1, \ldots, u_d), v = (v_1, \ldots, v_d)$$ are adjacent iff they differ in a single spot, i.e. $$| \{ i \mid v_i \neq u_i \} | = 1$$.

It is known that the metric dimension of $$H(d,q)$$ is $$\frac{(2 + o(1)) \cdot d}{\log_2(d)}$$ (1).

I’m interested in explicit (2) resolving sets for Hamming graphs in the region of $$d \sim 1000$$ that come reasonably close to their dimension metrics.

Unfortunately, since this lies outside of my area of expertise and I wasn’t able to come up with an answer in the literature, I don’t know whether this is even remotely possible.

(1) Since I’m unfamiliar with some of the notation in the published literature, I’m not 100% sure about this.

(2) as in computable with current day technology — ideally already known and publicly available

## Ubuntu resolving host takes more time

I’m using ubuntu 16.04 and browsers (both chrome and firefox) take about a minute to resolve a host. If I type the ip address of a web site in address bar , that web site instantly appears. For example if I type 172.217.9.142 I see google.com instantly but If I type google.com it takes time to reach to the site. I have updated my dns to google public dns servers. What could be the issue ? Any help is appreciated. Thank you!

## https version of web application is not resolving?

I am using Heroku to host which provides me a nice https: address:

https://some_random_string.herokuapp.com/ 

I use Namecheap to setup my DNS and I do this using:

CNAME Record | www | www.my_domain.herokudns.com. 

I found this information using heroku domains in the macOS bash console.

www.my_domain | CNAME | www.my_domain.herokudns.com

Everything works fine except the s gets dropped off the Heroku address when I use my custom domain.

## Resolving a stack with 2 recursive calls

I’m trying to refresh my skills in recursion and so far everything has gone well. However, I have never seen a problem where a string is the value of two recursive calls. Does the first recursive call ignore the rest of the statement? Is the 2nd recursive call still taken into account when it is resolved? I tried tracing it under the assumption that like a return statement, the first recursive call would break the loop. Therefore, I was under the impression that the rest of the code in the if statement would not be taken into account.

public class Example {     public static String encrypt(String word) {         int pos = word.length() / 2;         if (pos >= 1)              word = encrypt(word.substring(pos)) + encrypt(word.substring(0,pos));         return word;     }      public static void main(String []args){         System.out.println(encrypt("SECRET"));      } } 

While my expected output was “TETRET”, the actual output was supposed to be “TERCES.” Anyone mind explaining where my tracing or logic went wrong?
