Thanks for introducing me to Hammerspoon. I’m used to Ratpoison and after 1 hour of crude hacking I now have the features I miss most from it on macOS.
I’ve been running a Mozilla DXR instance for our internal code. Does anyone have experience with both? What are the advantages of sourcegraph over DXR?
I’ve also been running a Mozilla DXR instance. I’ve been very happy with it. Disclaimer: I have been a contributor to DXR in the past.
I only have minimal experience with Sourcegraph. Sourcegraph does fairly well in my opinion. The only annoying thing that I notice missing is “Find declarations”. You can search for references and it looks like any declarations are in that list but there is no easy way to find the declaration(s) separately.
The main problem with DXR is that it has no future. Development has been abandoned. Any development effort had migrated to SearchFox. DXR was explicitly designed to be able to index arbitrary code but it appears that SearchFox may be designed only to index Firefox. I’ve never tried to use it so I don’t know how easy it would be to get your own custom code indexed by a SearchFox instance. With the recent layoffs at Mozilla I doubt even SearchFox is going to be getting much work done on it. DXR only works with ElasticSearch 1.7.x and not newer versions which is becoming increasingly difficult to deal with.
Sourcegraph has two different ways to index your C++ code: lsif-cpp and lsif-clang, with the latter being the newer, recommended option. The lsif-cpp indexer is based on the DXR clang plugin. Compare https://github.com/sourcegraph/lsif-cpp/blob/master/clang/dxr-index.cpp with https://github.com/mozilla/dxr/blob/master/dxr/plugins/clang/dxr-index.cpp.
If you want to see what using Sourcegraph is like, they have a version at https://sourcegraph.com/search that indexes a bunch of public repos from GitHub. They have the DXR GitHub repo indexed so we can search within that.
For example, here are all the places where the string ->get appears in C++ files
And here are all the references to the function getFileInfo (look in the bottom frame)
Thanks for the explanation! I had a closer look and it seems pretty good. If I ever have to setup a code searching tool again it will probably be sourcegraph. Our current setup still runs on Ubuntu 16.04 which will lose support in 2021. I remember trying to get DXR running on Ubuntu 20.04 but it was too much of a pain due to dependencies on old software (like the old Elasticsearch). The only potential issue with sourcegraph is that multi-branch indexing is still experimental and we will need that. At the moment I think Mozilla’s future is too uncertain to invest much time in searchfox.
Like the author I think having your own mail server isn’t worth it in most cases. But I do think it’s useful to have your own domain for email (and using an email service that supports custom domains). This way you’re never locked in to a particular email service because you can easily point your MX record to another one.
Using your own domain has its risks too. If you miss a renewal payment, perhaps due to an errant email filter or an unusually long illness, you might lose control of it. Not only is it a major hassle—the new owner gains access to every account that can be reset by email without 2FA (i.e., most of them).
That doesn’t necessarily mean using your own domain is a bad idea, but after many years doing that I’ve been slowly transferring some eggs out of that basket.
I have crucial things (such as domains, but also water, electricity, …, phone service) set up with automatic direct withdrawal on a bank account that won’t run dry anytime soon. Not worth the hassle to check every invoice on those before the fact, especially since, given that they maintain crucial things, I took some care to choose providers I think I can trust with that as much as I can trust with them providing a reasonable service.
That’s a good point. I have a yearly reminder in my calendar and have auto-renewal enabled, for me that’s good enough. I wonder how mail providers handle this actually. If someone stops paying for their account and it gets deleted, can someone else register using that same email?
Most registrars will give you a reminder (or several) a few weeks before your domain expires. Assuming you keep up on that inbox (you should), it’s not too difficult. Many will park the domain for a time period after it expires too to prevent scalpers. Obviously if you’re super out of commission for a month, you probably have other things to worry about than your email.
