QUESTION
I noticed this package is deprecated, per the documentation here: https://cloud.google.com/appengine/docs/standard/go/go-differences
What is the correct way to log on Go 1.12+ without losing log levels by simply printing? (DEBUG/INFO/WARNING/ERROR/CRITICAL/etc.)
...ANSWER
Answered 2021-May-16 at 14:43You have at least 2 solutions :
- Use cloud.google.com/go/logging
- Use a generic logging framework (like
logrus
) and a special Stackdriver adapter to have logs with the right format and right level in Stackdriver logging
This is the default solution I think :

I am trying to use the library direct_cloud_upload to upload directly a file to a Google Cloud Storage Bucket without going through my cloudrun (to bypass the 32Mb request limitation).
Unfortunately, I consistently have this error: No file was submitted. Check the encoding type on the form. on the admin fontend when I try to upload a file, even though the file is sucessfully uploaded to the storage.
There is obviously something I am missing, here is my code:

I am currently in the process of making a website for a minecraft server. It is going quite well although it is still in it's infancy. However I have a very stubborn margin on the left which no matter what I try I cannot get rid of. I am not great at web development so maybe there is something that I haven't seen in the html or css.
[Edit] Forgot to add this when initially writing this, I have actually looked at questions asking similar things on here but none of the solutions worked.
Here you can see the margin on the left

QUESTION
I'm a beginner on golang. Every time I remove the go 1.13
, it suddenly goes back again. I'm not sure why. It has something to do with GoLand?
ANSWER
Answered 2020-Sep-03 at 10:14You are probably using Go 1.13 to develop your application.
In this case, whenever you run a Go command, like go build
, go list
, go test
, go mod tidy
and others, the go.mod
file will be modified to have some formatting included, and add missing directives, like the Go version that's compatible with that module.
So, go 1.13
is added to the file automatically, not by the IDE. You can reproduce this by running any of the commands that I listed above.
QUESTION
I hope to be as clear as possible. I'm trying to implement a function that, given two tetrahedra, checks if they intersect with each other. I am working with python and the only library I am using is NumPy. To describe a tetrahedron I use its 4 vertices which are each described by coordinates [x, y, z].
...ANSWER
Answered 2020-Nov-01 at 07:30Why not formulate a convex optimization problem, or precisely a feasibility problem using the plane inequalities that you have? Let's say, the two tetrahedra can be represented as A1.X + d1 <= 0
and A2.X + d2 <= 0
where the 4 rows of A1
and A2
store the a, b, c
of four planes corresponding to the two tetrahedra in ax + by + cz + d <= 0
, and column vectors d1
and d2
store the constants ie d
. And also note that A1.X
is matrix multiplication.
Represent (x, y, z)
as the vector X
.
Now basically you want to solve a feasibility problem for X
like this:
QUESTION
sorry for my bad english, hope you can understand what kind of problem do I have. So, here is the code and what it does is to resize the div.cards. I mean, when I have the window on fullscreen the table shows correctly the div.cards. So, when I start to change the size of window, some of those cards changing the offsetHeight in some rows (always depends on the text on them). I've attached the image of my table (with non-fullscreen window). So, as you can see, when I changed my window, the cards are changed the offsetHeight so, what I already achieved is to apply the same height to all div.cards with the most tallest div.card in the row. Where I'm still stuck, is: when I return the window to the fullscreen, those div.cards should go back to their original offsetHeight, but still unable to understand how to do that.
I was already tried, like putting the offsetHeight of all my div.cards into array then restore them somehow, but no success. my table
...ANSWER
Answered 2020-May-21 at 12:44I found the solution by myself:basically I introduced an array which stores the max OffsetHeight in the row, then applies it to all div.cards, after finishing the row it's cleanups so he can fill the data for the new row eccetera...

How can I cache my modules in codebuild using AWS provided image (Go 1.12)?
BackgroundI'm trying to cache go modules in codebuild using the go image (1.12) from AWS.
Trying to cache /go/pkg/modAfter digging deeper, I found that there is no /go/pkg
folder in that image. Hence, when I tried to cache /go/pkg
it would throw an error.
Error mounting /go/pkg/mod: symlink /codebuild/local-cache/custom//go/pkg/mod /go/pkg/mod: no such file or directory
Even after I run go mod download
(which will create the /go/pkg/mod
, it won't cache the folder because codebuild cannot mounted it earlier).
This is my codebuild.yml

I've almost completed migrating based on google's instructions.
It's very nice to not have to call into the app-engine libraries whatsoever.
However, now I must replace my calls to app-engine-standard memcached.
Here's what the guide says: "To use a memcache service on App Engine, use Redis Labs Memcached Cloud instead of App Engine Memcache."
So is this my only option; a third party? They don't even list pricing on their page if GCE is selected.
I also see in the standard environment how-to guides there is a guide on Connecting to internal resources in a VPC network.
From that link it mentions Cloud Memorystore. I can't find any examples if this is advisable or possible to do on GAE standard. Of course it wasn't previously possible but now that GAE standard has become much more "standard", I think it should be possible?
Thanks for any advice on the best way forward.
...ANSWER
Answered 2019-Sep-25 at 23:09I've been thinking about this. 2nd gen instances have twice the ram, so if global cache isn't required (as in items don't change once created - (name items using their sha256)), you can run your own local threadsafe memcache (such as https://github.com/dgraph-io/ristretto) and allocate some of the extra ram to it. It'll be faster than Memcache was, so requests can be serviced even faster, keeping the number of instances low. You could make it global for data that does change, by using pub/sub between instances, but I think that's significantly more work.
QUESTION
The Go package, google.golang.org/appengine, provides IsDevAppServer which reports whether an App Engine app is running in the development App Server (e.g. localhost:8080
). However, this does not work unless the (deprecated) standalone SDK is used. See appengine.go#L57 for the implementation.
New GAE apps written in Go are basically a regular web server that can be compiled and started locally like any go program;
- old;
dev_appserver.py
- new;
go run main.go
Detecting a development server can be useful for to prevent CORS issues when running locally:
...ANSWER
Answered 2020-Jan-05 at 12:27The App Engine Standard Go environnement sets a number of environment variables automatically. You can have a look at the list here.
You can check if they are set and if they aren't, then your code is running locally (or at least not deployed). Or you can set the NODE_ENV
environment variable to development
on your machine (in your shell where you run your app locally, not in the app.yaml file) and check for its value. It'll be set to production
when running on App Engine.
