Fero is a new way to write fast, scalable, stateful services that are also very resilient to failures and a breeze to operate. (fero ls, whilst running test that spins up 10 servers, 10 clients, fires 100 messages from each client, waits till replicated to all nodes, then tears down).

Inside docker, it seems that I cannot compile my gRPC micro-service due to this error:
...ANSWER
Answered 2020-Sep-07 at 00:39The gist of this error is that the version of binary used to generate the code isn't compatible with the current version of code. A quick and easy solution would be to try updating the protoc-gen-go
compiler and the gRPC library to the latest version.
go get -u github.com/golang/protobuf/protoc-gen-go
then regen the proto

QUESTION
I'm trying to use txdb for migrating my database inside an isolated transaction, for the purpose of testing code that interact with the database and also for tests with the migrations themselves. But every time I run my code an error is returned and some warnings are yell by Gorm:
...ANSWER
Answered 2019-Aug-16 at 02:09The problem seams to be that gorm
uses the first gorm.Open
argument as a dialect name (it has a set of predefined dialects) and not as a database/sql
driver name.
So you need to use a gorm
known dialect name as the first argument, in this case you want "postgres"
since you will be using postgresql as the underlying database hence you need gorm
using the corresponding sql dialect.
Then you tell gorm
to use the "txdb"
driver and "tx_1"
as the connection url.
This seem to work:
QUESTION
I have schema (Oracle 11g R2):
...ANSWER
Answered 2019-Mar-09 at 12:33From this blog in Oracle magazine, here is what happens if you use an ORDER BY
clause in a window function without specifying anything else:
An ORDER BY clause, in the absence of any further windowing clause parameters, effectively adds a default windowing clause: RANGE UNBOUNDED PRECEDING, which means, “The current and previous rows in the current partition are the rows that should be used in the computation.” When an ORDER BY clause isn’t accompanied by a PARTITION clause, the entire set of rows used by the analytic function is the default current partition.
So, your first query is actually the same as this:
QUESTION
I have a 4 different executable program, you can consider that those are empty rectangle same sized windows, and i want to run those exes in one qt qml window.
a,b,c,d are different executables that fixed same size, and x is a windows that written in qt5.11/qml quick2, how can i do that in qt/qml project, any ideas?
I am trying with window container but no progress. The exe is writing its window id to a text and i am reading from that text.
...ANSWER
Answered 2018-Sep-18 at 10:06You are basically asking how to to create a contained windowing system. This is neither trivial, nor even possible in some operating systems.
If your 4 "executables" are QML code you have access to, you can easily compose them in a single executable.
If they are 3rd party applications, it ain't so easy. It is possible to do that under linux, by utilizing wayland, or even possibly using some X API. But on windows you don't really get that kind of access, at the very least, I haven't found a way to do that, the OS controls the process windows and there isn't much you can do about it.
It might be possible to use the low level GUI APIs windows possibly offers, and if possible, hide the decoration for the 4 windows, and compose the windows so they are on top of your QML application window, and scale and move the 4 windows by code as your QML application window scales and moves.
At any rate, it seems you have wildly underestimated the complexity of implementing this, mostly because it is not an unreasonable expectation that one should be able to do that, but the reality of the situation is different. Windowing systems are very much still black boxes, things people aren't supposed to be meddling with.
QUESTION
I'm using Axios in the frontend of my project and needed a way to redirect the user to the login page in case he wanted to used expired tokens (the refresh token is invalid for the backend), I found a boilerplate code on the web that looked easy enough to adapt for my tech stack (ReactJS with no Redux):
...ANSWER
Answered 2018-Dec-12 at 21:54It is a good problem, and I did not know about axios interceptors. Anyway, I found a solution for this problem. The main thing is that you have to wrap your interceptor setup in a function, so you can pass the history object as a parameter. And you need the history object. One possible solution is to create one and provide the same history object to the Router as well the wrapped interceptor setup.
QUESTION
in order to have the right image and the right link everytime I share on Facebook, here's what i've done on my Wordpress/Woocommerce header:
...ANSWER
Answered 2017-Aug-14 at 04:07It seems like the issue is with your og:url tag. Each time I re-scrape with the sharing debugger it is different. To me, this suggests the get_permalink()
method is not returning a consistent result.
FYI, the og:url
meta tag is not required, so an easy fix here is just to leave it off. You only really need it if you have multiple URLs to access the same resource and you want to let FB's crawler which is URL is the canonical one.
