Hi all, I've advertised this tool and wrote a blog post about it even, but never really announced it here or in Slack. I thought a forum would be a better place for feedback than Twitter or something so I figured I'd post here. You can find the project here: https://github.com/tmaiaroto/aegis

[go-nuts] Gob encoding of maps is not consistent, should this be fixed?

inputs do not result in the same outputs. Note that consistent encoding of the same value is *not* specified in the list of goals in https://blog.golang.org/gobs-of-data (in fact it is not mentioned at all). However, it could be considered a desirable feature :) Regards, Tom -- You received

[go-nuts] Deleting the /r/golang subreddit

This is the most ridiculous, short sighted, and I'll advised thing I've seen suggested on this list for a while. Are we also going to remove every article written about go in a newspaper, magazine, or blog because editors and journalists did something idiotic? Because if that's the case, we're

Thanks guys for your suggestions. I am going to try: 1. GODEBUG=netdns=go+2 or GODEBUG=netdns=cgo+2 2. Running with just IP addresses to eliminate DNS 3. Creating a minimal program to reproduce latency and post here I agree that creating a ReverseProxy object every time is inefficent with

[go-nuts] httputil.ReverseProxy adding 100+ ms of latency on localhost - any ideas?

a very beefy machine! (8core 3.4Ghz Amd64) Anyone have any insights into httputil.ReverseProxy, or have any ideas where to begin? The method is here: https://github.com/twitchyliquid64/pushtart/blob/master/src/pushtart/webproxy/handler.go#L61 Cheers, Tom -- You received this message because

Done. I've also added a link to github.com/golang/geo, a library for geometry on the sphere. On Monday, November 14, 2016 at 11:25:19 PM UTC+1, Daniel Whitenack wrote: > > Thanks Tom! I think it would be great to add a few of these here: > > https://github.com/gopherds/resources

[go-nuts] [ANN] Go geospatial libraries: geometries, GeoJSON, WKB, KML, PostGIS, GPX, polyline

A quick announce of a few libraries for geospatial applications that are now mature and battle-tested: https://github.com/twpayne/go-geom : efficient geometry library, using a high-performance cache-friendly data representation (more info

Re: [go-nuts] Re: Best practices for upgrading go with existing GOPATH?

Aha, now I understand. I managed to reproduce the problem and the failure was occurring while running go vet after the build target (which runs go build on all our packages). Switching to go install to build the packages cleared the problem right up. On Thu, 15 Sep 2016 at 20:19 Dave Cheney

[go-nuts] Re: Best practices for upgrading go with existing GOPATH?

Thanks for the quick response :) Great to hear that the go tool is intended to catch this. The problem was typically seen when running our default make target, which uses build for the build itself, but has some sanity checking and code generation steps first, with tools like glock, errcheck

[go-nuts] Best practices for upgrading go with existing GOPATH?

We've recently migrated from Go 1.6 to 1.7 within our engineering team, and have been experiencing some binary compatibility issues (as is to be expected) that have usually been corrected by emptying $GOPATH/pkg and rebuilding - this was recommended but as is the case with manual steps, people
