H3/H2 Net Card – ODROID – wonder how well pfSense supports it

Posted by jpluimers on 2025/04/18

I wonder how well [Wayback/Archive] H3/H2 Net Card – ODROID is supported by pfSense. It is an M.2 based PCIe network card that adds 4 ethernet ports of 2.5 gigabit each to an ODROID H2 or H3 series (so you have 6 ports total), ideal for some hefty router.

Pictures (from the above link) of the board, cases and mainboard below.

But first: Realtek NICs is not vendor supported on FreeBSD (which pfSense and OPNsense are based on).

VSoft Technologies – Vincent Parrett on “Code Signing with USB Tokens”

Posted by jpluimers on 2025/04/17

It has been quite a while since I had to do code signing, but sooner or later that will change. When that happens, I need to re-read these:

A signal of the future WebAssembly/emscripten is giving us: a database served on a static web page

Posted by jpluimers on 2025/04/17

From a quite a while back; apparently it ended up in the drafts in stead of the blog queue:

[Wayback/Archive] Ian Miell on Twitter: “A signal of the future WebAssembly/emscripten is giving us: a database served on a static web page: … The possibilities are dizzying. Also, I’ve thought for a while that if I had to put money on it, SQLite will outlast every other database out there.”

The combination of Emscripten and WebAssembly is cool as it allows you to run C/C++ based code in most Web Browsers at near-native speed (though the standard is open and can just as easily outside that realm).

Delphi “array of const” to “varargs” – Stack Overflow

Posted by jpluimers on 2025/04/16

Just in case I ever think “oh, I might try want to go the Variadic function arguments way in Delphi” again, I must remember “maybe not a good idea” and re-read these posts:

Note that this example, despite the description indicates it is, it is actually not varargs by array of const (which requires using TVarRec as under the hood it is an open array of TVarRec): [Wayback/Archive] How to create functions that can accept variable number of parameters such as Format().

Then some Free Pascal links, which is different from, but also similar to Delphi:

DEF CON 30 – stacksmashing – The Hitchhacker’s Guide to iPhone Lightning and JTAG Hacking – YouTube (using Raspberry Pi Zero and hand modified lightning extension cable)

Posted by jpluimers on 2025/04/16

From a few years back when Lightning debugging cables were either expensive, hard or not to get at all: [Wayback/Archive] DEF CON 30 – stacksmashing – The Hitchhacker’s Guide to iPhone Lightning and JTAG Hacking – YouTube.

Basically it is a Raspberry Pi Zero with adapted firmware connected to half a lightning extension cable.

A textual description (I wish it was linked from the above video) is at [Wayback/Archive] stacksmashing – The hitchhacker’s guide to iPhone Lightning & JTAG hacking – DEF CON Forums, which in turn refers to:

git config: list all variables and their default values – Stack Overflow

Posted by jpluimers on 2025/04/15

Empirically, these are show the same behaviour where “command 2″and “command 3″are documented, but still present a lot as the only solution in blog posts and help sites:

git config commands
command 1: list command 2: --list command 3: -l what config is shown
git config list --local git config --list --local git config -l --local --local config for current repository
git config list --global git config --list --global git config -l --global --global config for the current user
git config list --system git config --list --system git config -l --system --system config for all users
git config list git config --list git config -l all 3 levels of config combined, for convenience
without telling which configuration setting is on which level

Based on [Wayback/Archive] git config: list all variables and their default values – Stack Overflow (thanks [Wayback/Archive] Matteo Meil): Read the rest of this entry »

Rephrasing error messages into heulpful messages

Posted by jpluimers on 2025/04/15

The problem with error messages is that they just displays errors as a fact without providing the user of future steps.

Offer them with a helpful, actionable message instead.

Not just for people with a visual impairment, I added readable text to the image below.

Parallel hashing on MacOS

Posted by jpluimers on 2025/04/14

Now that I have had an Apple silicon for a while, which has enough cores to perform parallel work, this is how I calculated a bunch of hashed from a lot of large files:

  • find . -type f | xargs -P 0 -n 1 md5 -r
  • find . -type f | xargs -P 0 -n 1 shasum --algorithm 1
  • find . -type f | xargs -P 0 -n 1 shasum --algorithm 256

I contemplated about using GNU parallel, but that is not installed by default on MacOS and I was already familiar with xargs.

Argument meanings can be found at these locations:

Moet het raam dicht?

Posted by jpluimers on 2025/04/14

Weet voor je naar bed gaat of je vliegtuiggeluid kunt verwachten.

Ben jij iemand die elke avond wakker ligt als er weer een vliegtuig voorbij komt? Of houd je je ramen ‘s nachts uit voorzorg potdicht om het geluid buiten te houden?

Deze site stuurt je voor je naar bed gaat een mail als er verwacht wordt dat vliegtuigen die nacht je slaap kunnen verstoren. Tijdens nachten waarop je geen mailtje krijgt kun je dus gewoon je raam open houden!

Van [Wayback/Archive] Moet het raam dicht?

Ze maken gebruik van deze bronnen (de laatste is inmiddels verhuisd):

Way harder than I anticipated: How To Share Discord Profile Link

Posted by jpluimers on 2025/04/11

Some of the people I know are not on any of Signal, WhatsApp, Google Chat, or other usual direct message platforms.

This left Discord, which I use more (at least weekly) than Facebook Messenger (once a month or so).

Sharing a user-link there proved to be quite a bit more difficult than I anticipated: it even involves enabling developer mode!

The steps are at [WaybackSave/Archive] How To Share Discord Profile Link [Copy & Share]

Found via query: [WaybackSave/Archive] share direct link to discord account – Google Suche
