            Fastest way to clear group with a lot of shapes / multithreading
            Asked 2022-Feb-21 at 20:14

            In my JavaFX project I'm using a lot of shapes(for example 1 000 000) to represent geographic data (such as plot outlines, streets, etc.). They are stored in a group and sometimes I have to clear them (for example when I'm loading a new file with new geographic data). The problem: clearing / removing them takes a lot of time. So my idea was to remove the shapes in a separate thread which obviously doesn't work because of the JavaFX singlethread.

            Here is a simplified code of what I'm trying to do:




            Answered 2022-Feb-21 at 20:14

            The long execution time comes from the fact that each child of a Parent registers a listener with the disabled and treeVisible properties of that Parent. The way JavaFX is currently implemented, these listeners are stored in an array (i.e. a list structure). Adding the listeners is relatively low cost because the new listener is simply inserted at the end of the array, with an occasional resize of the array. However, when you remove a child from its Parent and the listeners are removed, the array needs to be linearly searched so that the correct listener is found and removed. This happens for each removed child individually.

            So, when you clear the children list of the Group you are triggering 1,000,000 linear searches for both properties, resulting in a total of 2,000,000 linear searches. And to make things worse, the listener to be removed is either--depending on the order the children are removed--always at the end of the array, in which case there's 2,000,000 worst case linear searches, or always at the start of the array, in which case there's 2,000,000 best case linear searches, but where each individual removal results in all remaining elements having to be shifted over by one.

            There are at least two solutions/workarounds:

            1. Don't display 1,000,000 nodes. If you can, try to only display nodes for the data that can actually be seen by the user. For example, the virtualized controls such as ListView and TableView only display about 1-20 cells at any given time.

            2. Don't clear the children of the Group. Instead, just replace the old Group with a new Group. If needed, you can prepare the new Group in a background thread.

              Doing it that way, it took 3.5 seconds on my computer to create another Group with 1,000,000 children and then replace the old Group with the new Group. However, there was still a bit of a lag spike due to all the new nodes that needed to be rendered at once.

              If you don't need to populate the new Group then you don't even need a thread. In that case, the swap took about 0.27 seconds on my computer.

            How to log production database changes made via the Django shell
            Asked 2022-Jan-27 at 17:42

            I would like to automatically generate some sort of log of all the database changes that are made via the Django shell in the production environment.

            We use schema and data migration scripts to alter the production database and they are version controlled. Therefore if we introduce a bug, it's easy to track it back. But if a developer in the team changes the database via the Django shell which then introduces an issue, at the moment we can only hope that they remember what they did or/and we can find their commands in the Python shell history.

            Example. Let's imagine that the following code was executed by a developer in the team via the Python shell:

            Setting up multi-release JAR unit tests
            Asked 2022-Jan-26 at 09:21

            I have a project that uses a lot of reflection, also on "new" Java features such as records and sealed classes. I'm writing a class like this:



            Answered 2022-Jan-04 at 16:07

            To test a MRJAR the classes must be packaged as a jar, so don't use surefire with target/classes, but instead use failsafe during the verify phase. And you must run it at least twice, once per targeted Java version. I would write a unittest, that works for all Java versions, but might skip certain tests.

            Share media between multiple django(VMs) servers
            Asked 2022-Jan-15 at 10:58

            We have deployed a django server (nginx/gunicorn/django) but to scale the server there are multiple instances of same django application running.

            Here is the diagram (architecture):

            Each blue rectangle is a Virtual Machine.

            HAProxy sends all request to example.com/admin to Server 3.other requests are divided between Server 1 and Server 2.(load balance).

            Old Problem:

            Each machine has a media folder and when admin Uploads something the uploaded media is only on Server 3. (normal users can't upload anything)

            We solved this by sending all requests to example.com/media/* to Server 3 and nginx from Server3 serves all static files and media.

            Problem right now

            We are also using sorl-thumbnail.

            When a requests comes for example.com/,sorl-thumbnail tries to access the media file but it doesn't exist on this machine because it's on Server3.

            So now all requests to that machine(server 1 or 2) get 404 for that media file.

            One solution that comes to mind is to make a shared partition between all 3 machines and use it as media. Another solution is to sync all media folders after each upload but this solution has problem and that is we have almost 2000 requests per second and sometimes sync might not be fast enough and sorl-thumbnail creates the database record of empty file and 404 happens.

            Thanks in advance and sorry for long question.

            You should use an object store to save and serve your user uploaded files. django-storages makes the implementation really simple.

            If you don’t want to use cloud based AWS S3 or equivalent, you can host your own on-prem S3 compatible object store with minio.

            On your current setup I don’t see any easy way to fix where the number of vm s are dynamic depending on load.

            If you have deployment automation then maybe try out rsync so that the vm takes care of syncing files with other vms.

            Merge separate divergent size and fill (or color) legends in ggplot showing absolute magnitude with the size scale
            Asked 2021-Dec-13 at 03:52

            I am plotting some multivariate data where I have 3 discrete variables and one continuous. I want the size of each point to represent the magnitude of change rather than the actual numeric value. I figured that I can achieve that by using absolute values. With that in mind I would like to have negative values colored blue, positive red and zero with white. Than to make a plot where the legend would look like this:

            Is there a way to enforce correct spelling of features?
            Asked 2021-Nov-24 at 20:28

            Let's assume I have the following feature defined in Cargo.toml:



            Answered 2021-Oct-13 at 03:05

            When RFC 3013, "Checking conditional compilation at compile time", is implemented, there will be warnings for a #[cfg] referring to a feature name that is not declared by Cargo, just as you're asking for. However, the implementation only just got started (Sep 28, 2021).

            The means of operation described in the RFC is just as you suggested, ‘cargo would pass down the flags to rustc’.

            It may be worth noting that this will not check all conditions appearing in the source text; as described in the RFC:

            This lint will not be able to detect invalid #[cfg] tests that are within modules that are not compiled, presumably because an ancestor mod is disabled.

            So, it will not confirm that all #[cfg(feature)] are valid on a single cargo check — you will need to test with your various features or combinations of features. But those are the same combinations that you would need anyway to check for compile errors in all of the regular source code that could be enabled; once you do that, the lint will assure you that you don't have any #[cfg(feature)] that are never enabled due to a typo.

            SQLAlchemy - Adding a ForeignKeyConstraint to a many-to-many table that is based on another relationship
            Asked 2021-Oct-11 at 01:42

            Forgive me if this has been answered elsewhere. I've been searching SO and haven't been able to translate the seemingly relevant Q&As to my scenerio.

            I'm working on a fun personal project where I have 4 main schemas (barring relationships for now):

            • Persona (name, bio)
            • Episode (title, plot)
            • Clip (url, timestamp)
            • Image (url)

            Restrictions (Basis of Relationships):

            1. A Persona can show up in multiple episodes, as well as multiple clips and images from those episodes (but might not be in all clips/images related to an episode).
            2. An Episode can contain multiple personas, clips, and images.
            3. An Image/Clip can only be related to a single Episode, but can be related to multiple personas.
            4. If a Persona is already assigned to episode(s), then any clip/image assigned to the persona can only be from one of those episodes or (if new) must only be capable of having one of the episodes that the persona appeared in associated to the clip/image.
            5. If an Episode is already assigned persona(s), then any clip/image assigned to the episode must be related to aleast one of those personas or (if new) must only be capable of having one or more of the personas from the episode associated to the clip/image.

            Trust issue while sending a post to my API since DST Root CA X3 Expiration
            Asked 2021-Oct-01 at 15:05

            I have a C# api running on a aws S3 with ubuntu. This API is use by a website, a windows application and a xamarin app deployed on Samsung android devices.

            Since today 16:00 (paris time), the android part is not working anymore, I have a "trust issue". Clearly it seems to be related with DST Root CA X3 Expiration (No release on my side and the timing is perfect).

            But I don't understand why...

            1. SSL certificate

            I checked my SSL certificate and regarding let'sencrypt forums, I have one of the path base on "ISRG Root X1". The second one is base on "DST Root CA X3" (expired). I renew them anyway to be sure, but still the same certificate path. (and no problem for chrome to contact them).

            1. Internet with https is working

            I can reach internet with a webview inside the app (to my website in https)

            1. Can't connect using restsharp

            When I use RestSharp to contact my server, I have the trust issue.

            My android devices are all the same: Samsung A7 tab, half up to date, the other half was update in august, all of them with Android 11. So theorically they are "not concerned" with this certificate expiration.

            Can the problem come from Xamarin or RestSharp ? Maybe my server certificate ?

            EDIT Ok half resolved.... If I go to the "Trusted Root Certificates folder" in my android device (don't know the exact name), If I disable the "Digital Signature Trust Co. - DST Root CA X3", it's working again !

            Not a "real solution" since I need to update something like 150 devices... 2 options in my mind

            • Can I force RestSharp to use a certificate more than another ?
            • Is it just because Android know the expiration date is 30/09 and still use it because we are still the 30/09 and everythin will work Tomorow ?

            EDIT 2 resolved.

            Thx to all of you, sorry I should have been able to validate this answer before some post, but stackoverflow was on readonly mode this night and I fall asleep after that.

            What I did (not sure if all step are mandatory).

            1/ I updated the certbot since mine was < 1 (check with certbot --version)

            We’ve had similar issues today, unfortunately we were using older Amazon Linux on elasticbeanstalks. Upgrading to the latest Ubuntu build in your case should fix your issues.

            The issue we had was the Amazon Linux version trusted certificate service was always adding the expired root certificate.

            The reason restsharp is having problems is probably because it’s trying to do something like a curl request behind the scenes and is doing a handshake to verify the validity of the ssl cert when sending a request. The way it does this is checks it against certs that are trusted on the server, which includes the expired certificate.

            See here for Ubuntu builds that have the latest certs upgrade https://ubuntu.com/security/notices/USN-5089-1
