For everyone of you who do not know the Django Web Framework and couldn’t care less, here is a summary of the philosophy behind Broke:. Broke take advantage of the latest 'onhashchange' event, if present, and if not it will fake one. Generally Broke uses the 'elements' method to trigger 'broke.request' events instead of the 'hashchange' method. Please refer to the 'events' documentation for more insight.

QUESTION
We recently upgraded a web application to Django 4 which now, by default, adds a
Cross-Origin-Opener-Policy: same-origin
header to http responses, which can cause window.opener
to be null
in the child window. This broke one of our pages where we had a child window (for SSO auth) sending a postMessage()
back to the parent window when it was done doing its thing.
I know I can work around that by manually setting that header to unsafe-none
, or structuring those pages differently, etc., but I'm curious what is potentially unsafe about the child window having access to window.opener
?
Browsers keep window.opener
pretty locked down, and there's not much that child windows can do with it other than calling postMessage()
and a couple of other minor things.
Given that it is so locked down, what about it is unsafe? Can someone give an example of something damaging that a child window can do with window.opener
that the browser will allow?
ANSWER
Answered 2022-Apr-15 at 19:55This is briefly noted on MDN on the page about noopener, which refers to this blog post.
Directly quoting this blog:
TL;DR If window.opener is set, a page can trigger a navigation in the opener regardless of security origin.
and
This is a relatively harmless example, but instead it could’ve redirected to a phishing page, designed to look like the real index.html, asking for login credentials. The user likely wouldn’t notice this, because the focus is on the malicious page in the new window while the redirect happens in the background.
You should redesign the flow of the login, so that it does not need the unsafe header. Especially if you accept arbitrary links from users.
QUESTION
I am using a company-hosted (Bitbucket) git repository that is accessible via HTTPS. Accessing it (e.g. git fetch
) worked using macOS 11 (Big Sur), but broke after an update to macOS 12 Monterey.
*
After the update of macOS to 12 Monterey my previous git setup broke. Now I am getting the following error message:
...ANSWER
Answered 2021-Nov-02 at 07:12Unfortunately I can't provide you with a fix, but I've found a workaround for that exact same problem (company-hosted bitbucket resulting in exact same error).
I also don't know exactly why the problem occurs, but my best guess would be that the libressl library shipped with Monterey has some sort of problem with specific (?TLSv1.3) certs. This guess is because the brew-installed openssl v1.1 and v3 don't throw that error when executed with /opt/homebrew/opt/openssl/bin/openssl s_client -connect ...:443
To get around that error, I've built git from source built against different openssl and curl implementations:
- install
autoconf
,openssl
andcurl
with brew (I think you can select the openssl lib you like, i.e. v1.1 or v3, I chose v3) - clone git version you like, i.e.
git clone --branch v2.33.1 https://github.com/git/git.git
cd git
make configure
(that is why autoconf is needed)- execute
LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib -L/opt/homebrew/opt/curl/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include -I/opt/homebrew/opt/curl/include" ./configure --prefix=$HOME/git
(here LDFLAGS and CPPFLAGS include the libs git will be built against, the right flags are emitted by brew on install success of curl and openssl; --prefix is the install directory of git, defaults to/usr/local
but can be changed) make install
- ensure to add the install directory's subfolder
/bin
to the front of your$PATH
to "override" the default git shipped by Monterey - restart terminal
- check that
git version
shows the new version
This should help for now, but as I already said, this is only a workaround, hopefully Apple fixes their libressl fork ASAP.
QUESTION
So I right click on the solution > add > new project > find azure function > choose template > create that
And then nothing happens. If I swap to folder view, I see a new folder made for the function, but its an empty folder.
Weirdest thing is, this was working perfectly fine and a moment later, it became how it is right now. I've not updated vs in between, I've not restarted in between. It was literally closed vs, opened again, and then vs broke.
Older solutions that has functions in them, tried creating a new one, doesn't work same story. Made new solutions and start it off with creating a function, didn't work as well. Reinstalled vs, also did not help, still the same issue. Any ideas how I broke vs?
Also, this works from powershell, I can create functions from there and then go back to vs to add an existing project. However the functions I've build using this method had runtime errors (I think) when I publish them into azure. Regardless, I really would like to be able to create functions normally in vs.
...ANSWER
Answered 2022-Mar-22 at 12:55As we can see from the comment section of the question, the solution was:
- Go into Tools -> Get Tools and Features
- download the .Net desktop development
As Maybemonday described in his/her comment, functions can be created afterwards.
QUESTION
So, fundamentally, this question is Not opinion-based. I seriously pursuit this issue objectively without feeling mostly arisen from the predominant opinion - Why is extending native objects a bad practice?
and this quesion is related but unanswered questions:
Should the extension of built-in Javascript prototypes through symbols also be avoided?
The first question is already closed as they say it's opinion based, and as you might know in this community once a question is Banned, however we modified it, moderators will never bother to re-open. That is the way how the things work here.
For the second question. For some unknown reason, the question has been taken more seriously and not considered as opinion based although the context is identical.
There are two parts to the "don't modify something you don't own" rule:
You can cause name collisions and you can break their code.
By touching something you don't own, you may accidentally overwrite something used by some other library. This will break their code in unexpected ways.
You can create tight dependencies and they can break your code.
By binding your code so tightly to some other object, if they make some significant change (like removing or renaming the class, for example), your code might suddenly break.
Using symbols will avoid #1, but you still run into #2. Tight dependencies between classes like that are generally discouraged. If the other class is ever frozen, your code will still break. The answers on this question still apply, just for slightly different reasons.
Also, I've read opinions(how can we discuss such a thing here without "opinion" base?), they claim
a) Library code Using Symbols exists and they may tweak Symbol API (such as Object.getOwnPropertySymbols())
b) extending object property with Symbol is not different from non-Symbol property fundamentally.
Here, for the major rationale of untouching Object.prototype
is due to #1, almost all answers I saw claimed that and we don't have to discuss if there is no Symbol usage.
However, Using symbols will avoid #1 as they say. So most of the traditional wisdom won't apply anymore.
Then, as #2 says,
By binding your code so tightly to some other object, if they make some significant change (like removing or renaming the class, for example), your code might suddenly break.
well, in principle, any fundamental API version upgrade will break any code. The well-known fact is nothing to do with this specific question. #2 did not answer the question.
Only considerable part is Object.freeze(Object.prototype)
can be the remaining problem. However, this is essentially the same manner to upgrade the basic API by some other unexpectedly.
As the API users not as API providers, the expected API of Object.prototype
is not frozen.
If some other guys touch the basic API and modifies it as frozen, it is he/she who broke the code. They upgraded the basic API without notice.
For instance, in Haskell, there are many language extensions. Probably they solve the collision issue well, and most importantly, they won't "freeze" the basic API because freezing the basic API would brake their eco.
Therefore, I observe that Object.freeze(Object.prototype)
is the anti-pattern. It cannot be justified as a matter of course to prevent Object.prototype
extension with Symbols.
So here is my question. Although I observe this way, is it safe to say:
In case of that Object.freeze(Object.prototype)
is not performed, which is the anti-pattern and detectable, it is safe to perform extending Object.prototype
with Symbols?
If you don't think so, please provide a concrete example.
...ANSWER
Answered 2022-Mar-17 at 03:18Extending the Object prototype is a dangerous practice.
You have obviously done some research and found that the community of javascript developers overwhelmingly considers it to be a very bad practice.
If you're working on a personal project all by yourself, and you think the rest of us are all cowards for being unwilling to take the risk, then by all means: go ahead and modify your Object prototype! Nobody can stop you. It's up to you whether you will be guided by our advice. Sometimes the conventional wisdom is wrong. (Spoiler: in this case, the conventional wisdom is right.)
But if you are working in a shared repository, especially in any kind of professional setting, do not modify the Object prototype. Whatever you want to accomplish by this technique, there will be alternative approaches that avoid the dangers of modifying the base prototypes.
The number one job of code is to be understood by other developers (including yourself in the future), not just to work. Even if you manage to make this work, it is counterintuitive, and nobody who comes after you will expect to find this. That makes it unacceptable by definition, because what matters here is reasonable expectations, NOT what the language supports. Any person who fails to recognize that professional software development is a team effort has no place writing software professionally.
You are not going to find a technical limitation to extending the Object prototype. Javascript is a very flexible language -- it will give you plenty of rope with which to hang yourself. That does not mean it's a good idea to place your head in the noose.
QUESTION
Recently I was having a problem installing an npm package (that used node-gyp). I tried upgrading the minor version of node from version 16.13.0 to 16.13.1 and upgrading my angular cli from 13.0.2 to 13.2.0. Once I got the package to install I generated a library with ng g library new-library
. I don't know what what actually broke it, but now whenever I try to build alibrary it produces an error. I try ng build my-lib

QUESTION
I have many scheduled queries running on a project and it is getting hard to keep track of which script or query is breaking. Is there a way that I can add send a slack notification after each scheduled query runs successfully?
This would hopefully let me go through the logs on slack each morning to see which query broke.
...ANSWER
Answered 2022-Mar-02 at 16:14You can use Cloud Logging and Notification Channel to achieve your goal.
In a nutshell what we gonna do is that we will setup logs-based alert policy which will notify Slack channel (configured via Notification Channel).
First, please create a channel connected with Slack - steps can be found here.
Now let's focus on BigQuery. Please go to the "Schedules Queries" page in BigQuery and select (click) any query.
Please click again on the query details to get more information.
"Run details" box will appear on the right side of the screen. Please click the "View in Logs explorer" button.
Now, we are in the Logs Explorer. Please click the "Create alert" button.
Please provide an alert name, and click "Next".
In the second step of creating logs-based alert policy ("Choose logs to include in the alert") you need to create an inclusion filter (more information here), for example (to catch logs from all BigQuery scheduled queries):

Answered 2022-Feb-06 at 12:04Spring has it's spring application context which is working as a container of beans. The BeanFactory
represents spring's inversion of control container. What it does is exposing beans to the application. When your application requires a bean which is not available then it throws NoSuchBeanDefinitionException

I think your question and the root cause is best answered in the below question. Hope it will five you insights of the problem.
What is a NoSuchBeanDefinitionException and how do I fix it?
QUESTION
Last night I saw the episode 7 of the Squid game tv series. The episode has a game with binomial distribution in the bridge.
Specifically there are 16 players and a bridge with 18 pair of glasses (one pure glass and one safe glass).If one player happened to choose the pure glass then the glass couldn't stand the weight of the player and the glass broke. The next player had the advantage that he/she was starting from the position that the last player had and continues the binomial search.At the end 3 players happened to cross the bridge.
So i was wondering: It is like, I have 16 euros in my pocket and I play head or tails with p = 1/2
. Every time I bet on heads. If the coin flip is head then I earn 0 and if is tails I lose 1 euro. What is the probability of hitting 18 times (consecutive or not) heads and to be left 3 euros in my pocket.
I tried to simulate this problem in R:
...ANSWER
Answered 2021-Oct-16 at 13:02Here is how I think you can model the game in R. The first version is similar to what you have: there's a 50% chance of guessing correctly and if the guess is correct, the players advance a tile. Otherwise they do not, and the number of players decrements by 1. If the number of players reaches 0, or they advance to the end, the game ends. This is shown in squid_bridge1()
