QUESTION
I'm trying to use imagemagick
to generate PNG images from an SVG for use in a PWA. I'm having trouble working out which image is used when by the PWA. To debug this I'd like to annotate each generated PNG image with an index so I can tell which image the PWA uses in several different scenarios.
Below is an example of the command I'm using to create a 128x128 maskable PNG (10% margin) with white background from a source SVG.

QUESTION
I am updating my app with new library releases and I got an issue with my database. The released app currently using Room version 2.2.6 with FTS4. Currently having LONG for rowid
. The app runs smooth and no problem. But I want to use Room version 2.3.0 and according to the docs:
An FTS entity table always has a column named rowid that is the equivalent of an INTEGER PRIMARY KEY index. Therefore, an FTS entity can only have a single field annotated with PrimaryKey, it must be named rowid and must be of INTEGER affinity. The field can be optionally omitted in the class but can still be used in queries.
I should use INT not LONG.
...ANSWER
Answered 2021-Jun-15 at 04:11An FTS entity table always has a column named rowid that is the equivalent of an INTEGER PRIMARY KEY index.
In brief SQLite's INTEGER does not imply a Java/Kotlin Integer/Int/int it is a column affinity/type.
If you look at the Datatypes in SQLite3 then an INTEGER can be up to 8 bytes (64 bit signed). Which in Java/Kotlin is long/Long.
Further evidence can be seen with the SQLiteDatabase insert
convenience method as it returns the id (rowid) of the inserted row not as an int but as a long.
Returns long - the row ID of the newly inserted row, or -1 if an error occurred.
SQLiteAutoincrement explains about rowid and that in theory it can be from 1-9223372036854775807 (you can even have negative values).
As such, it is wrong to use int/Int/Integer for the rowid as in theory (not that likely in practice), the rowid can be larger than an int/Int/Integer.
I should use INT not LONG.
I'd suggest that you should use Long. It makes no difference to the data as SQLite will store an integer in as little space as it can. Furthermore, it makes no difference to the table(s) that room creates as the COLUMN TYPE will be INTEGER.

I'm building app to learn Hibernate on PostgreSQL. And I'm currently trying to add variable to database that has OneToOne relationship.
First, I create two tables in my database with schema below. On person_detail
table it has primary key that's also foreign key to person
table.
Then I created two classes, Person
and PersonDetail
. PersonDetail
is child of Person
that has OneToOne relationship. And I use code below to add person
with personDetail
as attribute.
ANSWER
Answered 2021-Jun-14 at 14:17I see that you have primary key in table person_details
as foreign key to person
table, you can use @PrimaryKeyJoinColumn

As discussed in Discover concurrency in SwiftUI, views can make use of the new .task { }

Answered 2021-Jun-14 at 21:22The problem is that your document class already selects a bibliography style, which you can't change afterwards. Two workarounds:
use the style your document class sets by removing
\bibliographystyle{IEEEannot}
from your codeif you actually do need the other style, save
olplainarticle.cls
under a new name and change l.8\ProvidesClass{olplainarticle}[06/12/2015, v1.0]
to the new name, remove line 43/44\RequirePackage{natbib} \bibliographystyle{apalike}
from the new .cls file and then change\documentclass{olplainarticle}

Answered 2021-Jun-13 at 11:09If you move the chunk

into the closure, your code compiles. I can't quite answer why declaring chunk
outside the closure results in a lifetime error for the borrow of text
inside the closure, but the chunk
Option
looks superfluous anyways and the following code should be equivalent:
