During holidays I found about #IBM Plex: https://www.ibm.com/plex/

Love this font! Best thing from IBM in years.

I'd guess that some years and we are predestined to see a triumph of #AI exploitation.

I'd guess there's opportunities in that area for behavioral exploitation, making it do unwanted things.

Even more so there's opportunities for scavenging "confidential leaks" from large LM's, to downright reverse engineering. Sometime in-house codebase might be seeded by mistake to a public LM...

Or hackers could exploit your network and instead of copying any data they would use LM as an indirect path to scavenge good quality enough information to meet the goals.

If I was working on offensive security like for some intelligence department, I'd put a lot of resources on exploiting the AI assistants for instance. Exploiting that functionally would open countless doors.

Of all of call codebases I've seen, compiled and successfully tested including Symbian OS, AOSP, Chromium etc. I think just as a build #Servo is one of the worst I've seen so far. It has a nice site, progress and everything but IMHO getting nice and easy build should be a primary target.

I'll give another shot tomorrow on compiling that mess :-)

I tried for fun to do my first trials on macOS because I thought that it is Rust so everything must be great. Was a mistake that I still regret ever doing that. I don't even want to begin how badly planned it is. I'll give it a shot with my Fedora system next time.

I already said this once but if you do your work in #GNOME, for most casual business use GNOME Web is a functional tool. And it has the #Firefox sync.

I turn Firefox on, only on my leisure time. The name rings to me like s.. night club in 1st place.... i.e. not something I should eagerly use for committing any business.

Has been pretty obvious equation in my case longer than the ad-gate.

It reminds to be seen ofc whether/if Mozilla starts to do same with Firefox as Google did with Chrome, i.e. I would not hold my breath of the sync feature working forever in this open manner.

Fedora turns on Firefox prototype advertiser measurement crap by default. You probably want to turn it off. People might want to file bugs for other distributions if they've done the same.

with all these #AWS, #Azure etc. developer certificates around, I wonder if there is a "zero certificates for life" #certificate that I could apply for somewhere?

My apartment is about 7 min walk from central railway station of Tampere and I get these all the time. I really have to fight myself of not fuzzing in...

One of the best foods ever: Georgian national dish hatsapuri. Competes strongly with Portugalian street food classic prego in my charts.

Now that I leaned to use Goblin with Mach-O binaries, and how I find my way to symbol address through those ways, I think as next step I'll write a my-purposes-only disassembler using Goblin and Capstone's #Rust bindings.

I have sort of this fuzzy big picture in my head what I might want to do with that and perhaps with using Aya EBPF sheanigans but have to do bunch or trials and errors first

Sort of interesting territory experiment anyhow despite successes and failures. Generally I'm more interested on Rust when it comes to kernel what can be done in QA side from user space than kernel code per se.

What I think of Biden/Trump? Pretty much the same feeling that I had when I did this track with my Slovakian-Finnish friend Vlado in 2020: https://globalfishmafia.bandcamp.com/track/i-dont-feel-anything

I was in Portland OR when 2016 elections happened, which was pretty cool I think or once in a lifetime historical experience, mind the result. Or actually, it is not my concern what I might mind the result. I only focus taking stand in the votes where I have a legit standing point in the first place.

E.g. I have a voting ticket for Finnish parliament, EU and LF deciding bodies. So I focus on those and deal with sometimes unfortunate reality.

Binary parsing with #Rust and #goblin https://jarkko.codeberg.page/2024/07/13/binary-parsing-with-goblin.html

The next step is to use #Capstone bindings to disassemble the victim symbol.

For people concerned about #Mozilla #Firefox: #GNOME Web supports Firefox Sync out of the box.

Unfortunately many new open source projects have performance benchmarks that seem to be heritage of Apple marketing.

Zed editor is a great example of this. There's so many moving parts missing here that I could write a book just listing those one by one ;-) This is objectively marketing propaganda because absolute timing values without context and environment do not have any other meaning than giving preferred impression.

Examples of reasonable ways to analyze performance can be found from e.g. https://www.akkadia.org/drepper/cpumemory.pdf.

I guess I’ve activated to post random stories about #vim lately ;-) There’s so much hate for it, especially from some members #neovim community, so I just want to show that there is also other side of the story. In other words, there are people who pick ā€œjustā€ Vim purely based on technical advantages.

It is a bit over year since Bram Moolenaar died so I guess this is also good timing in that sense (RIP) ;-) Remembering that by migrating my vim files to vim9script šŸ¾

Just learned that #Servo is independent project these days because #Mozilla laid off all of its staff in 2020. #Rust was originally developed specifically for this project. So I guess we have now three competitive web engines instead of two: #Gecko, Servo and #WebKit. servo.org #rustlang

On #macOS, I’ve found that best way for me to manage #vim installation specifically is to just download the dmg and install pkg given that it auto-updates and contains all the command-line versions (instead of using homebrew or macports):

$ ls -1 /Applications/MacVim.app/Contents/bin
gview
gvim
gvimdiff
gvimtutor
mview
mvim
mvimdiff
mvimtutor
view
vim
vimdiff
vimtutor
