            Model.evaluate returns 0 loss when using custom model
            Asked 2021-Jun-15 at 15:52

            I am trying to use my own train step in with Keras by creating a class that inherits from Model. It seems that the training works correctly but the evaluate function always returns 0 on the loss even if I send to it the train data, which have a big loss value during the training. I can't share my code but was able to reproduce using the example form the Keras api in I changed the Dense layer to have 2 units instead of one, and made its activation to sigmoid.

            The code:



            Answered 2021-Jun-12 at 17:27

            As you manually use the loss and metrics function in the train_step (not in the .compile) for the training set, you should also do the same for the validation set or by defining the test_step in the custom model in order to get the loss score and metrics score. Add the following function to your custom model.



            How do you do GRPC authentication in an istio mTLS setup?
            Asked 2021-Jun-15 at 14:41

            I have bunch of GRPC microservices and they are using self signed certs. I add authentication info to the GRPC channel which is then used to identify endpoints and provide right services.

            Now I want migrate to Istio mTLS.

            In phase one, I got Istio to BYPASS all GRPC connections and my services works as it is now.

            In Phase two, I want to hand off TLS to Istio, but I am stuck on how to pass the authentication information to GRPC?

            How do you handle auth in Istio mTLS setup?

            GRPC can support other authentication mechanisms Has anyone used this to inject Istio auth info to GRPC? any other suggestions on how you implemented this in your setup

            I am using go-lang just in case if this can be useful to provide any additional information.




            Answered 2021-Jun-11 at 09:21

            One way of doing this is using grpc.WithInsecure(), this way you don't have to add certificates to your services, since istio-proxy containers in your pods will TLS terminate any incoming connections.

            Exposing business classes from business library in Google Apps Script
            Asked 2021-Jun-15 at 10:30

            So, I am working on an MVVM-based core SDK for use any time I am developing some Google Apps Script based software, called OpenSourceSDK. It contain core business logic, including base classes to extend. For example, the file Models/ in it is defined to be:



            Answered 2021-Jun-13 at 22:53

            I was able to get it resolved, but the solution is...hacky.

            So, apparently, Google Apps Script exports only what is in globalThis of a project: just the functions and variables. No classes, no constants, ...

            Probably has a lot to do with how ES6 works, with its globalThis behavior. One can see that in action, by creating a dummy function, a dummy variable, and a dummy class in their local developer console:



            React: Flex-direction row not taking effect
            Asked 2021-Jun-14 at 21:00

            I know there are a thousand similar questions, but mine has almost no context, generic as can be, and right out of the box. Why is the flex-direction row property not taking effect?

            Since Fragment is a component, className goes to props object and does not pass as actual style.

            Just wrap the items in a div and give it the class:

            I use Flutter with Android Studio on a Mac.

            One day (today), I ran "flutter doctor" from the command line.

            It stated that my "cocoapods" was not good enough.

            change environment size on scale_colour_manual to assign colour to factors to use across multiples plots
            Asked 2021-Jun-14 at 12:17

            I need to make 5 plots of bacteria species. Each plot has a different number of species present in a range of 30-90. I want each bacteria to always have the same color in all plots, therefore I need to set an assigned color to each name. I tried to use scale_colour_manual to create a color set but, the environment created has only 16 colors. How can I increase the number of colors present in the environment created?

            the code I am using can be replicated as follow:

            When you know all your 90 bacci names in front of plotting, you can try.



            JxBrowser comvert html to pdf with 7.X release

            I want to convert an html file to pdf using TeamDev jxbrowser. I want to trigger it automatically wihout any extra print dialog or popup etc just by executing some code. And I also want to set some extra settings. In the 6.X versions I can see more detailed options by coding

            The Printing API that allows programmatically printing the currently loaded web page using the PDF printer is not available in JxBrowser 7. It's already on our roadmap. We do our best to introduce this functionality in one of the next versions.

            I recommend that you follow us on to be notified when this functionality is released.

            UPD: In JxBrowser 7.13 the Printing API has been extended with functionality that allows programmatically configure print settings and print a web page without displaying the Print Preview dialog. The API allows you to save the currently loaded web page as a PDF document. Read more at

            The following example demonstrates how to save a web page as PDF:



            Videos are playing too fast using OpenCV and PyQT5
            Asked 2021-Jun-14 at 10:44

            My GUI is able to play videos automatically when selected in the QListWidget. However, instead of normal speed, the videos play very fast. I use 720p Mp4 videos as examples and are placed in a certain folder. I tried using cv2.CAP_PROP_FPS and cv2.CAP_PROP_BUFFERSIZE, but they are both not working. I am using pyqtSignal in the QThread and the convert_cv_qt function which I saw in other guides. How do I play the videos in normal speed / frame rate?



            Answered 2021-Jun-14 at 10:44

            When you use VideoCapture with a file if you call "" you will obtain the next frame on the video, regardless of its actual framerate. Hence, you should use a "msleep" every time you capture a frame:



            Directory API query "NOT EQUAL"?
            Asked 2021-Jun-14 at 10:27

            I am trying to query the Directory api for users with orgUnitPath=/ but not equal to any sub OUs.

            I have read the following and it doesn't mention any "NOT EQUAL","!=", or "<>" operators.

            Is there any way I can accomplish this?




            Answered 2021-Jun-14 at 10:27
            "NOT EQUAL" is not part of the supported operators for the Directory API

            So, unfortunately, your only option to list all users and then filter the "NON EQUAL" values programatically within your code.



            Bulk out-of-order data import into QuestDB
            Asked 2021-Jun-13 at 22:11

            I'm looking into using QuestDB for a large amount of financial trade data.

            I have read and understood but my case is slightly different.

            • I have trade data for multiple instruments.
            • For each instrument, the microsecond-timestamped data spans several years.
            • The data for each instrument is in a separate CSV file.

            My main use case is to query for globally time-ordered sequences of trades for arbitrary subsets of instruments. For clarity, the results of a query would look like



            Answered 2021-Jun-13 at 22:11

            As of 6.0 you can simply append the CSVs to same table one by one given the table has designated timestamp and partitioned it will work.

            If your CSVs are huge I think batching them in transactions with few million rows will be better than offloading billions at once.

            Depending of how much data you have and your box memory you need to partition in a way that single partition fits memory several times. So you choose if you want daily or monthly partitions.

            Once you decide with partitioning you can speed up the upload if you able to upload day by day batches (or month by month) from all CSVs.

            You will not need to rebuild the table every time you add an instrument, table will be rewritten automatically partition by partition when you insert records out of order.
