Bash/jq hydrate() — transparent JSON-to-bash type converter
13 May 2026 @ 7:32 pm
Inspired by this post: https://stackoverflow.com/a/79914244
I wrote a utility function for scripts that consume JSON from API calls. Looking for a code review focused on correctness, edge cases, and design.
Background
I needed a clean, reusable way to map specific JSON paths to bash variables without scattering jq one-liners throughout the script or storing raw JSON strings in bash variables as a half measure.
The design principle: hydrate() is a transparent converter — JSON in, bash out, jq's native semantics preserved throughout. Nothing JSON-shaped should cross the boundary into bash.
Type conversion rules

How do I get values from a DataGrid Column?
13 May 2026 @ 7:23 pm
I am building WPF app and i am refactoring it to use a MVVM pattern, i have an issue with a DataGrid that is fed by an SQL query and has a column with buttons for each register in XAML like so:
<DataGrid Name="NestCards" FontSize="12" ScrollViewer.CanContentScroll="True" MaxHeight="400" ColumnWidth="*">
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Click="GetDetails">Details</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
It was the case that i was able to just use the sender as a button and handle it like that, no problem
Button pressed = sender as Button;
var nestName = Typ
What is the right way to add a custom shell command to my app in Windows 11?
13 May 2026 @ 7:16 pm
I used to use the following registry file to add a custom right-click menu option for my app for a .jpg file - and it works correctly in Windows 10. But this feature of my app does not work any more in Windows 11. (My installer does the equivalent of this reg file:)
[HKEY_CLASSES_ROOT\SystemFileAssociations\.jpg\Shell\Example\Command]
@="C:\\example.exe \"%1\""
The desired behaviour is that when you right-click a .jpg file in the Windows File Explorer, the custom command Example would appear in the context menu, and selecting it would launch the specified exe and pass the path to my process as an argument.
In Windows 11, the command doesn't appear in the right-click context menu. Note that the legacy menu can be accessed by holding Shift while right-clicking, and my custom command does appear in the legacy menu. But my intent is to have the command appear in the regular right-click co
Can OWASP Dependency-Check be used to check a specific product?
13 May 2026 @ 7:09 pm
We use a periodic OWASP Dependency-Check job to scan our Java applications.
It would be useful to also use OWASP Dependency-Check to scan other tools that are used in our system, but that are not formally dependencies of anything. This includes Java runtime installations and a database system.
Is there any way to make OWASP Dependency-Check scan those specified products?
For example, this is the CPE for the JDK version: cpe:2.3:a:eclipse:temurin:21.0.9
Can I give this as parameter to Dependency-Check to check in some way?
Or can I maybe create a dummy artifact in some way that makes it check that product?
Or maybe call the code in the scanner JAR file dire
How do I reproduce Coding2GO's CSS carousel?
13 May 2026 @ 7:08 pm
I'm tried making a carousel in HTML/CSS by following exactly Coding2GO's video: https://www.youtube.com/watch?v=KD1Yo8a_Qis
In the video, 6 elements are spinning in the carousel.

Qemu crashes my kernel as I try to run IDT interrupt as a test. Core dumped by qemu [closed]
13 May 2026 @ 6:52 pm
I have been making my kernel based on top of my own bootloader, and ive got all the hard things such as memory and other stuff working relatively good. However I have been trying to initialize idt(interrupt descriptor table) for a while for an x86_64 system. When ever I test an interrupt such as dividing by zero or do "asm volatile ("int $3");". just for testing purposes, this is what qemu says:
"
ERROR:system/cpus.c:504:qemu_mutex_lock_iothread_impl: assertion failed: (!qemu_mutex_iothread_locked())
Bail out! ERROR:system/cpus.c:504:qemu_mutex_lock_iothread_impl: assertion failed: (!qemu_mutex_iothread_locked())
Aborted (core dumped)
"
In the following github repo (look below). will have the whole kernel code, it will not have the bootloader because that is irrelevant regarding this matter as it is done well and not causing any issues related to anything. There will also be just the ".iso" file for thos
Using TypeScript, how do I strongly type PostgreSQL query results?
13 May 2026 @ 6:50 pm
I am writing a back end in TypeScript using Express and PostgreSQL. I use the pg npm package to connect to the PostgreSQL database and execute a query.
I want to perform some mapping and conversion on the response I get from the database. First, I want to type the response that I get from the query in order to avoid TypeScript warnings about properties that I know will always be in the response.
This is my code:
import { Pool } from 'pg';
const pool = new Pool({
// Config
});
const result = await pool.query('SELECT * FROM my_table;')
if (result.rows.length > 0 && result.rows[0]) {
console.log(result.rows[0].id);
}
I know that result.rows will be an array of objects, and each object has an id property. However, working with this property results in TypeScript warnings like Unsafe member access .id on an 'any' value.

The latest WebAIM Million report shows that detectable homepage accessibility errors increased over the past year.

2026 Predictions: The Next Big Shifts in Web Accessibility
22 December 2025 @ 11:22 pm
I’ve lived long enough, and worked in accessibility long enough, to have honed a healthy skepticism when I hear about the Next Big Thing. I’ve seen lush website launches that look great, until I activate a screen reader. Yet, in spite of it all, accessibility does evolve, but quietly rather than dramatically. As I gaze […]

Accessibility by Design: Preparing K–12 Schools for What’s Next
30 July 2025 @ 5:51 pm
Delivering web and digital accessibility in any environment requires strategic planning and cross-organizational commitment. While the goal (ensuring that websites and digital platforms do not present barriers to individuals with disabilities) and the standards (the Web Content Accessibility Guidelines) remain constant, implementation must be tailored to each organization’s needs and context. For K–12 educational agencies, […]
Up and Coming ARIA
30 May 2025 @ 6:19 pm
If you work in web accessibility, you’ve probably spent a lot of time explaining and implementing the ARIA roles and attributes that have been around for years—things like aria-label, aria-labelledby, and role="dialog". But the ARIA landscape isn’t static. In fact, recent ARIA specifications (especially ARIA 1.3) include a number of emerging and lesser-known features that […]
