I did see quite a few that double up, like 2 versions of url and a few others. Just had a quick play ... on arch linux `yay nushell-git` already works!!! One area where I got a bit stuck was around help. `man where` gave me nothing, `help w

There are 2 parts to the cost. 1. is the VM 2. is handling filesystem mounts across operating systems (2) can be debilitating in dev environments on Mac for example where you want to edit files outside the container but have the container h

by sams99 8y ago
absolutely if you have a filesystem heavy operation and are accessing files inside the container in aufs instead of a local mount, you are going to pay a massive docker tax.

A very interesting and important aside is that in Linux you pay almost no tax for using Docker. This is not the case on Windows and MacOS where there is a significant cost. That 8 minute spec run, also takes 8 minutes in docker. https:&#x2

I completely understand the concern here. If every change required an 8 minute wait it would be real sad for us. We use a tool called `rake autospec` at Discourse which is a smart test runner. I personally like the vim integration we built.

Absolutely disabled defender. When I started running the spec suite in WSL, defender went way up (so I gave it a break), pretty sure stuff would have been way worse with defender on. The prevailing recommendation though from the WSL team is

Unless you are looking to contribute to a project and kick off a project I would recommend sticking with the bigger players our there like nodebb/vanilla and so on. Getting stuff right is not easy, very few forum software platforms out

WSL is not technically a VM... The news is not the it is slower, it is how much slower it is. I found the number surprising given the prevailing wisdom out there was ... sure its slower, about 5-10% slower. The other news is that mac is slo

For us at Discourse we find Mattermost perfectly acceptable as a chat program. 10 second load times and slow/wrong notifications have not been a problem for us at all.

sort of, I run a VM on Windows using VMWare workstation, involves binary patching the vmware executable, but hey, cheaper than buying a mac.

That is a great call, an atom would struggle big time running plex, I have a Thinkcentre M92p which is tiny and silent, do wish it had a tiny bit more grunt but was pretty good value for $200.

At Discourse our biggest constraint we are fighting now is memory, not performance (don't get me wrong, I wish MRI was faster). JRuby is usually more memory hungry than MRI and getting reasonable boot time is not easy on JRuby. Additio

I dunno, maybe cause re-writing a 10 year old working app in another platform is not something that is easily achievable or even desirable. http://www.joelonsoftware.com/articles/fog0000000069.html

Sure, but what is stopping you from choosing a more efficient architecture for your Rails app? For example, we use pgbouncer transaction pooling, so our connection counts are low. Tons of caching is done in NGINX and first middleware in the

Something that is unclear to me here, can I origin pull from anywhere? or is this purely for compute engine now? Regarding free SSL are we talking SNI here or is this free non SNI HTTPS hosting?
