Assuming you're using vue-router (and you probably should be), then you'll want to use the beforeRouteLeave guard. The documentation even gives an example of this exact situation: beforeRouteLeave (to, from , next) { const answer = window.confirm('Do you really want to leave? you have unsaved changes!') if (answer) { next() } else { next(false) } }
A nice example for how to prompt a user to save unsaved changes before changing routes.

someGetter (state, getters, rootState, rootGetters) {
Note including all the parameters here is important. If you do not include all four and you want to use rootGetters for example:
someGetter (state, rootGetters) {rootGetters will be getters because getters is the second argument passed to this function and so you will not actually be on the root scope but instead the local scope.
To access rootGetters in another name spaced module:
someGetter (state, getters, rootState, rootGetters) { let value = rootGetters["module-name/getterName"](param1);

# scenario-1: delete in session: SA might set category_id of all chilren Products to None c1 = session.query(Category).get(1) session.delete(c1) session.commit() # scenario-2: delete without loading an object into the session: SA will perform no additional logic session.query(Category).filter(Category.id == 2).delete() session.commit()
Weird sqlalchemy behavior but totally an accurate statement. When using postgres and not specifying how to handle deletes, if you delete via object instead of filter.delete, sqlalchemy will set all children with foreignkey id's to None.

When you create a vue component you must give it a name:
<script> export default { name: "TodoItem", } </script> -
The following binds a class on a condition in order to apply conditional styling:
<div class="todo-item" v-bind:class="{'is-complete':todo.completed}"> -
Styling can be scoped to just the component with the scope denotation below:
<style scope> </style> -
When looping in the template the variable must be unique so we use v-bind:key and give it the id of the object as shown below:
<div v-bind:key="todo.id" v-for="todo in todos"> <h3>{{todo.title}}<h3> -

if you’re using user federation (things like single sign-on and OpenID Connect), JWTs become important because you need a way to validate a user’s identity via a third party.
-
If you’re building API services that need to support server-to-server or client-to-server (like a mobile app or single page app (SPA)) communication, using JWTs as your API tokens is a very smart idea.
-
If your website is popular and has many users, cache your sessions in a backend like memcached or redis, and you can easily scale your service with very little hassle.
-
in most web authentication cases, the JWT data is stored in a session cookie anyways, meaning that there are now two levels of signing. One on the cookie itself, and one on the JWT.
-
Almost every web framework loads the user on every incoming request. This includes frameworks like Django, Rails, Express.js (if you’re using an authentication library), etc. This means that even for sites that are primarily stateless, the web framework you’re using is still loading the user object regardless.
-
since JWTs are larger (in bytes) and also require CPU to compute cryptographic signatures, they’re actually significantly slower than traditional sessions when used in this manner.
-
This means that on most websites, the stateless benefits of a JWT are not being taken advantage of.

It's good practice to keep file loaded by content_by_lua_file at a minimum and place all processing logic into external modules. This allows lua_code_cache to work its magic and simplifies your testing.
Kinda counter intuitive but in a way it makes sense since require does built in caching and it makes it easier to test. This actually makes me feel a lot more comfortable making a utils area and just testing the functions in there.

import operator s = sorted(s, key = operator.itemgetter(1, 2))
Sort by multiple indexes.
-
to reverse to only one attribute, you can sort twice: first by the secondary s = sorted(s, key = operator.itemgetter(2)) then by the primary s = sorted(s, key = operator.itemgetter(1), reverse=True)
This makes sense, particularly from specification of sort order in Pandas, if I recall correctly you usually specify the primary last which makes me think on the backend implementation it does something similar to this where it sorts from the lowest priority to the highest priority.

Default: proxy_cache off;
So sounds like proxy caching is off by default.
-
Default: proxy_cache_lock off;
hmm...Ok this is off by default so probably not a bottleneck in that case.
-
Default: proxy_cache_lock_age 5s;
Again-seems like this should be a smaller timeout.
-
Default: proxy_cache_lock_timeout 5s;
This is a very long time! We should definitely shorten this. I actually wonder if this is perhaps why we are facing a bottleneck when we see a bunch of requests at once. When I performance tested, I ran without caching so it's possible the caching is actually bottlenecking us.
-
Sets an offset in bytes for byte-range requests. If the range is beyond the offset, the range request will be passed to the proxied server and the response will not be cached.
I don't see a need for this right now as it's not the range requests that are really the perceived slowness but it might be worth looking at later.
-
“GET” and “HEAD” methods are always added to the list, though it is recommended to specify them explicitly.
I wonder why?
-
If the value is set to off, temporary files will be put directly in the cache directory.
So use_temp_path should probably be set to off. I don't see a reason why we would need to first write them to a different directory.
-
Cached data that are not accessed during the time specified by the inactive parameter get removed from the cache regardless of their freshness. By default, inactive is set to 10 minutes.
This default seems like it should probably be set to minimally an hr-probably more. Cloudlflare is set at 4 hours which seems perfectly reasonable to me.
-
The special “cache manager” process monitors the maximum cache size set by the max_size parameter. When this size is exceeded, it removes the least recently used data.
So we might need to increase this?
-
Cache data are stored in files.
So it caches them on the file system by way of storing them in a temp file and renaming them. The default here says --. I thought nginx cached things by default so does this mean that's not the case or maybe it doesn't save them? Confused-need to investigate more.
-
Default: proxy_cache_min_uses 1;
This seems right for us.
-
The levels parameter defines hierarchy levels of a cache: from 1 to 3
Basically the same concept as a hardware cache with 1 I assume being the first cache that will be checked.
-
each level accepts values 1 or 2
I don't understand what this means.

Is anyone aware of a lua http lib that supports keepalive?
When sending a request you can pass the following keepalive settings which will keep the connection open:
local http = require "resty.http" local httpc = http.new() httpc:connect("127.0.0.1", 9081) local response, err = httpc:request({ path = "/proxy" .. ngx.var.request_uri, method = "HEAD", headers = ngx.req.get_headers(), keepalive_timeout = 60, keepalive_pool = 10, })

location / { proxy_pass http://backend; # You may need to uncomment the following line if your redirects are relative, e.g. /foo/bar #proxy_redirect / /; proxy_intercept_errors on; error_page 301 302 307 = @handle_redirect; } location @handle_redirect { set $saved_redirect_location '$upstream_http_location'; proxy_pass $saved_redirect_location; }
Usually the redirect is returned as the response and the client follows the redirect. This will follow a redirect inside nginx rather than the client.

The X-Forwarded-Proto request header helps you identify the protocol (HTTP or HTTPS) that a client used to connect to your load balancer. Your server access logs contain only the protocol used between the server and the load balancer; they contain no information about the protocol used between the client and the load balancer.
The load balancer may talk to the server via http so using $scheme in nginx when there's an AWS load balancer in front may lead to the $scheme being unexpectedly http instead of https.
http { map $http_x_forwarded_proto $original_scheme { "" $scheme; default $http_x_forwarded_proto; } }

I had a similar issue with nginx+passenger (for Ruby on Rails / Rack / etc.), and I confirm that by default, multiple slashes are collapsed (in both PATH_INFO and REQUEST_URI). Adding merge_slashes off; in the server context of the nginx configuration fixed it

non-blocking internal requests
Note ngx.location.capture only works on internal requests which means if you want to request an external endpoint dynamically then you need to setup something like below and call that internal endpoint instead of calling the external url directly.
Say for example you want to send a request to / endpoint with the thirdparty url as part of the path (
http:proxy-server.com/http://example.com).location /external/ { internal; set $upstream ""; rewrite_by_lua_file ./lua/get_external.lua; resolver 8.8.8.8; proxy_pass $upstream;Where lua/get_external.lua:
-- strip beginning '/' from uri path ngx.var.upstream = ngx.var.request_uri:sub(2)

set $template_root /usr/local/openresty/nginx/html/templates;
We should probably use this instead of root since root has other implications.

Because it can handle a high volume of connections, NGINX is commonly used as a reverse proxy and load balancer to manage incoming traffic and distribute it to slower upstream servers – anything from legacy database servers to microservices.
-
Dynamic sites, built using anything from Node.js to PHP, commonly deploy NGINX as a content cache and reverse proxy to reduce load on application servers and make the most effective use of the underlying hardware.
-
With its event-driven, asynchronous architecture, NGINX revolutionized how servers operate in high-performance contexts and became the fastest web server available.
-
NGINX has grown along with it and now supports all the components of the modern Web, including WebSocket, HTTP/2, and streaming of multiple video formats (HDS, HLS, RTMP, and others).
-
NGINX consistently beats Apache and other servers in benchmarks measuring web server performance.

use the REPOSITORY:TAG combination rather than IMAGE ID
Error response from daemon: conflict: unable to delete c565603bc87f (cannot be forced) - image has dependent child images
I really feel like this should be the accepted answer here but it does depend on the root cause of the problem. When you create a tag it creates a dependency and thus you have to delete the tag and the image in that order. If you delete the image by using the tag rather than the id then you are effectively doing just that.

This API function (as well as ngx.location.capture_multi) always buffers the whole response body of the subrequest in memory. Thus, you should use cosockets and streaming processing instead if you have to handle large subrequest responses.
So my interpretation of this is the request is issued, the entire response is buffered in memory, then res.headers is read from that buffer. I wonder if there is a way to cut off this buffer and close the connection early such that only the headers make it into the buffer for responses that are very large.

Nginx, by default, will consider any header that contains underscores as invalid.
Interesting.
-
This is a really great introductory article to how nginx works. Definitely worth a read!
-
While buffering can help free up the backend server to handle more requests, Nginx also provides a way to cache content from backend servers, eliminating the need to connect to the upstream at all for many requests.
This seems like something we might want to look into long term but also I wonder whether this is really necessary. I thought nginx also cached responses by default so in that scenario I don't think it would even go out to the upstream server anyway, it would just return the previous still valid response but maybe I'm missing something.

The health insurance here is about the best you will find. The company is employee owned, so you get stock(full stock ownership after 7 years). The benefits are pretty good - the only downside is the amount of vacation time and the ability to move up. It takes a lot of time to move up, and even in the high positions, you max out at four weeks of paid vacation after 15 years.
Seems like a pretty good summary.
-
Cheapest medical and dental insurance. Also you get stock every year and it adds and grows with you for your retirement. Starting pay is lower, but the stock and insurance makes up for it.
So maybe those benefits do make up for the $1 less in pay compared to Fred Meyer-at least this person thinks so.

Fred Meyer offers employees a stock purchase plan. Stock options are available for some employees.
So I'm not sure if grocery employees have access to this but note it's purchasing stock as opposed to being gifted stock by the company which is what Winco does (although of course there is a vesting period at Winco).

Stock option is called ESOP (Employee Stock Ownership Plan) and is the retirement plan WinCo gives all of its employees. Must be vested 5 years to receive 100% of stock.
Seems good.

Good health insurance, some 401k and HSA matching, vacation requests are not always accomodated
So they do have 401k and HSA and they have match-that's a plus but again might be job dependent.

Not sure what job this person had though.

Cashier - Hourly$11/hrRange: $9 - $1863 salaries$11/hr$9$1
Winco cashier pay is $11/hr. In general Winco is $1 less pay per hour than Fred Meyer but they also have stock and 401k benefits which is a huge plus although when you are making that little of income anyway do you really have money laying around to invest in those things anyways? Probably not would be my guess.
