🚒 iPhone vs Android 🚒

Round 394!

ok but in all seriousness, let's say I want to send some SMS/RCS using my cell, but I want to do that from the computer... should be feasible?

iPhone's iMessage: "we love our walled garden so much that NO ONE can send messages using a web interface, despite iMessage being an iCloud enabled app and the ecosystem having iCloud apps available online to any non-Mac -- but we decided that iMessage alone should never be usable on the iCloud web interface (because reasons?)"

Android via Messages App: "sure thing fellow Happy Camper! here you go! https://messages.google.com and it's just as secure as using the device itself."

Best part... Android's method WORKS ON FREEBSD!

💖 Lineage & Location 💖

Until very recently I never knew that my genetic grandmother had moved to Chicago, fell in love, and started a family. Prior to all of that she was certainly not in Chicago but somewhere entirely different, in a hospital, where she had to give my mother up for adoption.

Some decades later the story will unfold as her granddaughter moves to the same city, with a similar set of eyes, looking towards a new direction and renewed set of goals.

💗 Workstation Update 💗

a tradition continues: new job == new workstation (@home)

supermicro store finally stopped being broken, and now this is on order:

CPU: EPYC 4564P, 16C/32T @ 4.50GHz, 170W TDP
RAM: 4x 32GB DDR5-4800MHz ECC-UDIMM
GPU: either A4000 or P2200 from the bench
NVMe: 2x Samsung 990 Pro 2TB M.2
NICs: 2x 2.5G Intel i226v
OS: FreeBSD 14.x (of course) :freebsd_logo:

Should be fun. Probably should decide on dual-redundant PSU to replace the basic/boring platinum one from the stock chassis, but no rush.

@feld OpenVPN can go head to head with Wireguard on hardware optimized deployments, and at a substantially lower cost*.

The performance reality is often, nearly always, occluded in the modern tech user's mindset... unless they have first hand experience with encryption offload accelerators.

OpenVPN can have it's encryption and compression/decompression fully offloaded from the CPU (via QAT Integration for OpenSSL), which substantially increases the throughput performance and reduces latency. This acceleration is available on all of generations of Intel's QAT cards -- which notably have full support in FreeBSD and OPNsense and PFsense (among others) where that type of network accel is heavily used for advanced scaling solutions.

On but wait... what about Wireguard and its default reliance on Poly ChaCha20?... well, the newest generation of QAT (no longer PCIe AIC, but are directly on-die for certain Xeon and Atom C5/P5/P7 series SKUs) also include acceleration offload for Wireguard's chacha20-poly1305.

[*] Since Wireguard needs newer gen QAT for its ChaCha20 offload, which are only CPU on-die, OpenVPN can utilize older Intel CPUs with inexpensive gen1-2 QAT as PCIe cards.

Examples:
* Gen1 8950 ~$65: https://www.ebay.com/itm/375502192437
* Gen2 8960 ~$150: https://www.ebay.com/itm/186265281944
* Gen3: https://www.servethehome.com/welcome-to-the-intel-ice-lake-d-era-with-the-xeon-d-2700-and-d-1700-series/
Gen4+: Xeon (Sapphire Rapids) 6438N https://www.intel.com/content/www/us/en/products/sku/232397/intel-xeon-gold-6438n-processor-60m-cache-2-00-ghz/specifications.html

I have a decent amount of these options in my personal labs and production PoCs at various Corps, all super fun to work with. If it helps to sell the benefits, these are also used for similar performance gains on OpenZFS with native encryption and compression/decompression and maybe a little bit on checksumming. 💯

Maybe I should write a blog post with more details, perf metrics, pics, some code samples for integration.. ja?

@matuzalem @stefano

ADHD? certainly not!

I just happen to always juggle at least eleven concurrent personal projects with overlapping kanban sub-tasks and burndown charts...

and maybe those all need a place to... oh wait... wait... what's that server hardware notification from ebay?

right, as I was saying, ADHD certainly not!

I happen to always juggle at least ... twelve concurrent...

🤍 Appeal to the Browser Goddesses 🤍

Can we please make it a thing where 32GB of RAM isn't an insufficient amount for day to day web browser usage? Getting an OOM core dump for that reason is inexcusable.

- Should the Zoom browser app really need 2GB on a single tab when it's already downscaling a 1080p feed to 320p on an enterprise account?
- Should Amazon's website really need 1GB per tab just to view the cart or a ~800Mb for a single simple product page?
- Please remind me how an MKdocs fully static page with a single 400k image and no datatables or fancy JS somehow require 242Mb?
- Or perhaps shed some light on the requirement where Google's main page with a single search form somehow needs ~500Mb

There are no "good reasons" for these inefficiencies. We don't suddenly have better search fields or compressed jpegs now vs a decade ago with 1/10th of the system resources.

🩷 PsyTrance Mix ∆ Mittwoch Mittag 🩷

high intensity cardio deserves a hard baseline mix of classic tracks, and this one seamlessly melts away an hour nearly unnoticed (that's a good thing) 🤩

Obtained additional 2.5TB of NVDIMMs (5x 512GB Optane Series 200, for Ice Lake Xeons (LGA-4189))... the $/GB was too good to pass on, and these are new + shipping directly from Intel (not China hyperscaler decomms).

So... now begins the arduous task of comparative analysis for CPU SKUs and MB choices. Probably it makes sense to duplicate the existing Ice Lake build, but that's not as fun as obsessing over specs and possibilities.

generally I use ipmi SoL for remote access during kernel debugging, but laptops don't have a BMC... so there are a few options inline with netconsole (inc a porting commit of netconsole itself)

^ personal life tasks that filter to the forefront of conscious thought, just as soon as I woke up ~02:40

is this adulting? is this a hardware obsession? should I prioritize rabbits and chocolate and sociability more?

ooooooh so many early morning considerations...

@silverwizard rad! I've been looking for a new xmpp server host/community, considering spinning up a new one with ejabberd but oooh the time, always short on time.

irc clients, totally not easy to settle on for gui ones. hexchat is still kicking, and kde has a decent one, but there's always the option to return to irssi.

@silverwizard let's just say what needs to be said: IRC is still superior to Slack and its cloud-era chattypal garbage friends. there was/is a contender in XMPP but what happened... google camped out on the protocol and enshittified it as expected.

@dexter assumption of CDDL / GPL incompatibility aspects negating ZFS, generally I default to XFS instead of Ext4. including it in dracut/initrd (to be able to load at boot) is a simple one step change, which IIRC Redhat started doing on their installer back on vers 8.

@mia You've only listed the occasionally beneficial qualities of properly medicated ADHD, while having left off all of the very real and ever-present difficulties that it brings to daily life with or without adequate medication coverage.

Are you simply going to ignore the core qualities which define the condition's disabilty inducing parameters?

Remind me how wonderful those qualities are for the work place without the necessary medication to maintain order within the otherwise chaotic circumstances of neurocognitive dissaray, all resulting from an imblalance of neurotransmitter activation and transporter regulation. It is a neurological disorder which is often comorbid with an array of equally concerning and debilitating issues.

ADHD is a serious condition which requires serious medical care and often-times multifaceted treatment modalities. It's not just trivialities with fun and games about special super-powers.

@david_chisnall @matt I'd suggest that you don't bother bringing anything to do with systemd into any conversation about service management improvements for FreeBSD.

two hours of picking my way through .local, .config, and other userland data is causing a deep dissatisfaction with GUI apps that have no ability to export their settings to a file (ascii or binary, archive or otherwise).

Performance & Regressions -- How Orgs Ship Code to Production: https://prose.winterschon.com/2024/08/15/performance-regressions-how.html

Usually my mobile device wallpapers are atomic weapons tests images, reasons discussed elsewhere.

However, new phone, new state, new perspective, maybe a wallpaper which maintains a reminder of personal reality - instead of the tearing apart of fissionable elements.

Yes, it can be perceived as dark, which is it, but it's so much more than its surface expressions may imply.

Today, hopefully after a minor jaunt is complete, the international market will provide critical medication alternatives which our national pharma industry has decided are "not profitable **enough**". The "enough" part is unfortunate for the patients.

They're not happy with regular profit, it must be super-profit, and if it isn't then maybe they create a situation where the supply chain dries up from insufficient shipments. Besides, there's not really _that many_ people who need this, right? 😲

So, other countries may still carry the Rx, and the FDA still approves the Rx, and I can get a Rx written for it, but the manipulated supply chain requires acquisition via the international market.

I'll say one thing that remains true over the years: I've had much better health outcomes from engaging with the grey market than dealing with the insurance companies who dominate the provider matrix. Mexico, Canada, Costa Rica, SE Asian countries, oooh where would I be without your wares!?
