How difficult is it to wire a British house built in 1950? I got limited power sockets, the fibre comes into the house next to the front door & it would be nice to stick the WiFi AP in the direct centre of the house. How difficult is it to run ethernet cabling? I am not really a home DIYer so any tips would be appreciated.Please boost far & wide for coverage and many thanks in advance!

Tawanda :nix_snowflake_logo:A question for all the <a href="https://hachyderm.io/tags/selfhosting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#selfhosting</a> enthusiasts and <a href="https://hachyderm.io/tags/sysadmins" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmins</a> out there: I had a Go site on a VPS and recently decided to migrate to self-hosting Ghost on a Digital Ocean VPS (I was using Oracle before) and my site has become basically inaccessible. I checked the RAM usage in my admin and it's consistently above 90%. I have 1GB ram and figured I wouldn't need more since I don't get much traffic, but now everytime I try to open my site it takes forever to load.What I don't understand is that, on the Oracle VPS, I not only had my Go site, but also had Caddy, Plausible for analytics with a <a href="https://hachyderm.io/tags/postgres" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#postgres</a> DB and never had any issues. Now, all I have is the ghost site, mariadb, and caddy and nothing works.Do I need more RAM or is this a DO thing? Both the Oracle and DO VPSes are hosted in the EU which is pretty far from here, to be fair. I do suspect it's a RAM issue because I can't even ssh into the VPS. When I try to open my site, the connection just loads until it eventually times out.<a href="https://hachyderm.io/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linux</a> <a href="https://hachyderm.io/tags/go" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#go</a> <a href="https://hachyderm.io/tags/GhostCMS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GhostCMS</a> <a href="https://hachyderm.io/tags/nodejs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nodejs</a>EDIT: adding the link in case someone wants to check it out, could just be my distance from the server <a href="https://tawandamunongo.dev" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://tawandamunongo.dev</a>

BeefGrillerFor those unfortunate <a href="https://dice.camp/tags/Windows" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Windows</a> <a href="https://dice.camp/tags/sysadmins" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmins</a> like myself, realize that <a href="https://dice.camp/tags/gpupdate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gpupdate</a> takes flags, the most useful of which is /target:computer, which ignores user policies and implements computer/hardware policies. That is to say, forcing only computer policies makes things faster, if needed.

joatQuestion for fellow <a href="https://mastodon.scot/tags/sysadmins" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmins</a> : you try to add redundancy to your servers; RAID, dual PSUs, multiple clouds, replicated VMs, Ceph, Kubernetes, whatever, but do you apply the same logic to your personal devices? For example if your primary laptop were to die suddenly, do you have a spare? Maybe an older laptop in a similar configuration with copies of important data, or backups that would let you provision a new laptop quickly? How long before you could maintain your servers again?

Geekmaster 👽:system76:<a href="https://mastodon.social/@adastra1930" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@adastra1930</a> good advice! <a href="https://ioc.exchange/tags/hybrid" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hybrid</a> setups provide <a href="https://ioc.exchange/tags/fault_tolerance" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fault_tolerance</a> too. If the cloud provider goes down, or trunk connections are cut, or there's a massive public <a href="https://ioc.exchange/tags/DNS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DNS</a> outage, or even a large-scale power outage - you can still have <a href="https://ioc.exchange/tags/authentication" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#authentication</a> services, and some <a href="https://ioc.exchange/tags/connectivity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#connectivity</a> with internally hosted sites and services. Plus, managing an on-prem Domain Controller gives we <a href="https://ioc.exchange/tags/sysadmins" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sysadmins</a> the control on routes and content delivery for our users and devices, and we can pivot quickly to recover services should the Internets take a massive shit. Of course, there are limits to what can be done today without some <a href="https://ioc.exchange/tags/cloud" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cloud</a> services in place, or even <a href="https://ioc.exchange/tags/electricity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electricity</a>, but that's not the point here. There are fewer and fewer of us anymore that actually know how to spec and build out a <a href="https://ioc.exchange/tags/physical_server" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#physical_server</a> for a target environment, let alone how to make it play well with clouds. And don't get me started on <a href="https://ioc.exchange/tags/n00b" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#n00b</a> tech people's lack of understanding on how the <a href="https://ioc.exchange/tags/Internet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Internet</a> actually functions. It's a lost art form anymore lol. I still believe A+, and Networking Fundamentals (Level 1 & 2) courses should be required learning for anyone in computer science. Part of passing those courses should be building a PC, building a Server, and building a Network, from scratch. Then break/fix/break/fix until you "get it." We also need more <a href="https://ioc.exchange/tags/support" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#support</a> for <a href="https://ioc.exchange/tags/n00bs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#n00bs</a> landing <a href="https://ioc.exchange/tags/industry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#industry</a> jobs with quality <a href="https://ioc.exchange/tags/leaders" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#leaders</a> who actually <a href="https://ioc.exchange/tags/mentor" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mentor</a> them, making them better than they could be.
