recomment | Voice controlled recommender system

Suppose I have a list and maintaining it in ordered state. Can I isert new values into it with logarithmic complexity with code like this

So, I have setup my .zshrc to have a basic level of syntax checking by creating bindkey lines for basically all character generating keys and pointing them to respective functions that both generate the character and then call the syntax checker.

It is otherwise working perfectly, however I want to apply it to tab so that it will take into account $BUFFER changes from compinit, however calling compinit manually within the trap_tab function I created doesn't even call compinit.

Any help is much appreciated!

Below is the relevant bit. Just uncomment and recomment the bindkey and zle -N lines. When uncommented, even though compinit is called, I do not receive any autofill options when hitting tab.

I am trying to clone a git repository from a GOGS server which is located on a Raspberry Pi 3. It fails with the following complaint:

For simplifying our web services I'd like to introduce a custom MyObj class using the Jersey framework in version 2.34 and want to inject the created instances via the @Context annotation.

I have two questions:

1. Assuming a web service method @GET test(@Context MyObj obj), how can I control when instances of MyObj are created in respect to the execution of existing servlet request filters?

2. To create instances of MyObj, I already have a working example based on HK2's Factory's (see below). Since I observed that my factory class gets instantiated twice, and Jersey 2.26+ recomments to use the newer approach based on Supplier's, I tried to convert my example. Unfortunately, configure() won't be called in the provided Binder implements Supplier class, and thus, no objects get created. How can I get this working? (Btw., In both cases, Binder and BinderHK are registered via jersey.config.server.provider.classnames in my web.xml.)

Thank you for any help.

I'm working on a creating a highchart example, and I want to export the chart into PNG format. When downloading the PNG image, it displays differently than it does on the chart.

I have tried various approaches to add the title lines, but none of them are working for me.

When I try to open the site, the HTTP 500 error appears, and the Laravel log shows: "A non well formed numeric value encountered"

Here's a value of $sec before casting intval(($sec / 60) % 60). Value is 60.316000 and type of this value: string.

Any idea how can I fix this, in file index.blade.php where this function called (strings 29,50,86,122,150), code that's call it looks like this:

I know there have been a lot of times question was answered on stackoverflow about how to set row height for QTableView. I'm asking one more time but my question is not exactly about "how", at least not so simple. I'm setting row height successfully with help of Qt.SizeHintRole in data method of my custom model derived from QAbstractTableModel - see code below. (Also tried very similar example but with help of sizeHint() method of QStyledItemDelegate - the result is exactly the same.)

It works pretty good when I have MODEL_ROW_COUNT about 100 as in example below. But my dataset has ~30-40 thousands of rows. As result this simple application starts about 30 seconds with MODEL_ROW_COUNT=35000 for example.
The reason of this big delay is this line of code:
self.table_view.verticalHeader().setSectionResizeMode(QHeaderView.ResizeToContents)
Everything works really fast with MODEL_ROW_COUNT=35000 if I would comment this line. But in this case data() method is not called with Qt.SizeHintRole and I can't manipulate row height.

So, my question is - how to set row height on a per row basis for dataset with thousands of rows? Below example works but takes 30 seconds to start with 35 000 rows (after window is shown everything is fluent)...

At the same time if I use QSqlTableModel it doesn't have this problem and I may use sizeHint() of QStyledItemDelegate without big problems. But it's a mess to have too many delegates... May I subclass QStyledItemDelegate instead of QAbstractTableModel to implement my custom model? (I'm not sure that it will work as every source recomment to subclass QAbstractTableModel for custom models...) Or I did something wrong and there is a better way than usage of QHeaderView.ResizeToContents?

P.S. I really need different heights. Some rows in database have less data and I may show them in a couple of cells. But others have more data and I need extra space to display it. The same height for all rows will mean either waste of space (a lot of white space on a screen) or lack of essential details for some data rows. I'm using contant CUSTOM_ROW_HEIGHT only too keep example as much simple as possible and reproducible with ease - you may use any DB with any large table (I think I may re-create it even without DB... will try soon)

I would like to have some observable collections/sequences in Python that allow me to listen on change events, like for adding new items or updating items:

I want add a file into the jar package but this is a separate file from the java program, can I run it and if I can run it, how can I run it? Can you recomment anything?

Thanks.
