passionate nut who rants on irc and likes coreboot and openbsd. libreboot founder and lead developer (libreboot.org). bios on social media accounts are so asinine because you can't really say much that is meaningful. everyone has a different perception than you do. judge me on merit. every post by me reflects the opinion of my employer (also me). i don't know everything but i try to know enough - if i say something wrong, i want you to challenge me. they/them

14:48 <@leah> gonna go home tonight
14:48 <@leah> and work on libreboot
14:48 <@leah> that is a fact, not a threat

idk why i found it amusing but i did so posting it here. from #librespeech just now

only tonight, because i'm working on minifree orders all weekend. not only am i the founder / lead developer of libreboot (free/opensource BIOS), i sell it pre-installed via this company:

https://minifree.org/

i'm doing a major libreboot build system audit. improving code quality / fixing bugs

I made another interesting change earlier:

libreboot change: https://codeberg.org/libreboot/lbmk/commit/839ef680cd8f25650d8fb59a3e6fe6bf3f84786b

canoeboot change: https://codeberg.org/canoeboot/cbmk/commit/3e5db248dd3f730d1ddab61329bc52f125c23cd3

i regularly maintain sync between canoeboot and libreboot, ensuring that they have the same functionalities (with canoeboot excluding certain behaviours/code)

this change, on both projects, makes merging changes between them much easier, by reducing the number of merge conflicts

libreboot build system audit 5 is ongoing, and i'm keeping caoneboot in sync throughout.

Fun fact: I now own libreboot.net

https://libreboot.net/

Nothing special really. It just redirects to libreboot.org, which is the official domain name. I bought it just so I can redirect it.

But those who know of my antics over the past few years will find this fact highly amusing. I saw today that it was now available, so I grabbed it.

I'm sitting here working on orders. But in the morning I always read news. I found this amazing:

https://www.theguardian.com/commentisfree/article/2024/may/07/tories-reform-local-elections-rishi-sunak-culture-war

Finally, a fucking sane Conservative in the news. I'm a conservative myself, but I wholly oppose the current leadership of the party; it has been swayed this way or another by the extreme hard-right; the racists, the xenophobes, the shitstirrers - Susan Hall for instance (failed london mayor candidate) is a fucking nazi bitch.

All I want is sound money, sensible government.

I need a decent VPS host that specialises in #BSD, specifically
#OpenBSD based hosting. One that has a good track record for reliability, also good customer support, and general security practises.

I can google this, but I have a lot of BSD people following me, so I'm asking this here, because my followers will know better.

I'm moving all my self-hosted servers over to OpenBSD but some of it is intentionally outsourced, for a few reasons. If people can reply with suggestions that'd be super.

Just did my civic duty: I voted in today's local council elections (UK elections).

I backed the loser, if polls are to be believed, but that's OK.

Fun fact, I used to be a member of the UK Labour party, even ran for local elections in my local area; at the time, I was proud to beat the local liberal democrat in the ward I fought. 2018 local elections, Castle Point:

I don't support the Labour party anymore. My views have changed since then :)

Libreboot release soon. ETA May 2024; likely May 4th or May 5th. I'm in a crunch between now and then, patching up whatever I can - what's already there is essentially ready.

This is going to be a new stable release. The previous stable release was on 25 June 2023, and several testing releases have come out since.

Development has been at a more conservative pace since February 2024, because I said to myself on the day of the 20240225 release, that the next one would be stable. It will be so.

I've once again greatly reduced the Libreboot 9020 price. Base price for SFF now £258.

I've done this by excluding certain upgrades by default; i7-4790k, noctua fans, 32GB RAM upgrades etc are now add-ons. Base spec now i5-4570, 16GB RAM, 1TB SSD.

I've split SFF/MT into separate product pages. See:

https://minifree.org/product/libreboot-9020-sff/

https://minifree.org/product/libreboot-9020-mt/

This is a desktop machine with Libreboot pre-installed, replacing proprietary BIOS. Your choice of Debian Linux, other distro or a BSD system.

Mate Kukri, author of the Dell OptiPlex 9020 port in coreboot, has recently been working on an exploit for OptiPlex 3050 Micro, a skylake machine.

He has successfully disabled the Intel Bootguard and ported coreboot, and is interested in porting the ThinkPad T470 next. He posted a video showing coreboot on the 3050:

https://www.youtube.com/watch?v=32XtsvDjrk0

He's using SA-00086, a known bug in ME11 that allows own code execution. He's using it to disable the bootguard. WIP coreboot port: https://review.coreboot.org/c/coreboot/+/82053

Fun fact: countries have the right to retaliate when they are attacked by a foreign state or to otherwise defend themselves from attack.

People everywhere deserve the right to life, happiness and civil liberty. Being alive and healthy is a prerequisite to that.

Your government has the moral authority to provide the strongest possible deterrent to attack/invasion.

Ukraine, Palestine and Iran all have the right to respond to attacks on their sovereignty. But our media says the latter two don't.

When I do a Dell 9020 with Libreboot, any variant, I replace every fan with quieter Noctua fans which are premium quality designed in Austria - by comparison, the stock Dell fans are cheap, loud Chinese design.

Dell uses a non-standard connector, electrically compatible with regular PWM standard.

Adapters are available, but add greatly to cost and cable length, so I chop the old cable and solder it. Double-insulated; each wire insulated then all together, with heatshrink.

Here are photos:

I've madly reduced Libreboot 9020 prices:

https://minifree.org/product/libreboot-9020/

Intel i7-4790k, 32GB RAM, 1TB/2TB SSD. Choose Intel HD4600 / AMD Radeon RX6400 / RX 6600XT. GPU

Intel AX210 WiFi. Debian Linux, other distro or BSD of your choice.

Libreboot replaces proprietary BIOS/UEFI offering greater freedom; I lead the project and use sales to fund it.

Libreboot 9020 has PWM fan control now so fans are regulated. Runs much cooler without needing prior mods. Other costs cut, without reducing quality.

@whvholst As promised by @nemobis, my counter point:

I ship to the EU all the time. In particular, I use UPS for EU shipping, and they're efficient. Normally there's just a link on the tracking page where you can pay the customs charge which is equivalent to VAT plus a small handling fee of about 20 EUR.

So if 400 GBP for a machine, UPS charges you about 120 EUR.

Before Brexit, EU customers paid UK VAT 20%. Now they pay 0% UK VAT, and pay their own country's VAT. See:

https://minifree.org/delivery-and-return-policy/

libreleah,
@libreleah@mas.to avatar

@whvholst @nemobis Yeah so, basically, whatever the total price is during checkout: times it by 1.2 and that's the pre-Brexit price.

The post-Brexit tax is the pre-Brexit tax multiplied by1.05 (matching the dutch vat. I assume dutch, your name is dutch and you said 21% which is dutch vat) plus €20.

So, 400 GBP -> pre-brexit tax was 80 GBP.

Now it's 84 GBP, plus that handling fee, makes it about 100 GBP. Convert that into EUR (at today's rate, multiple of 1.17) and it makes 115 to 125 EUR.

libreleah,
@libreleah@mas.to avatar

@whvholst @nemobis The EU did something unprecedented in its history, in response to Brexit: it made trading easier, for low value items:

That handling fee would be a problem if what you're buying is £20.

Anything not exceeding 150 EUR has this rule: non-EU merchants can(must) sign up to the IOSS scheme; they charge your country's VAT rate during checkout, and file VAT in only 1 EU country. Before, you had to register in every EU country.

I deal in higher value so you pay VAT at the border.

libreleah,
@libreleah@mas.to avatar

@whvholst @nemobis one day maybe they'll have another lightbulb moment and make that the case for all goods, regardless of value. Then I'd just register for VAT in some eastern european country (where costs are lower) and charge dutch, german, spanish, french VAT, you name it, at checkout.

But yeah, the current rules do add like 2-3 days delay in customs. But the way things work is pretty efficient. I only use good couriers, they do it all for you. You just pay VAT and it arrives, no problem.

Pico Pi is such an amazing little tool. @riku maintains, in libreboot, a fork of pico-serprog. You can build it in lbmk for pretty much all RP2040-based dongles including Pico Pi, and then it becomes a cheap (but good) SPI flasher, far superior to the CH341a for these reasons:

  • Much better incoming power circuit (for 5v to 3.3v)

  • 3.3v logic levels by default - some CH341a are 5v which can damage 3.3v ICs

  • Generally higher build quality and more versatile, can be reprogrammed for many uses

I added a patch to Libreboot yesterday by Mate Kukri, author of the Dell OptiPlex 9020 MT/SFF coreboot port in Libreboot.

See: https://browse.libreboot.org/lbmk.git/commit/?id=6da91df6b9473628b02f4d5a1e0a801a49a2e6da

It adds PWM fan controls, so fans speed up when the system gets hot. Previously, fans ran at a constant low speed but my tests of stock cooling with 65w CPU, and 90w CPU (i7-4790k) with my cooling mods, showed temps about 85-90c, within spec.

EDIT: Previous stress test (prior to Mate's patch) here: https://mas.to/@libreleah/112184558614560980

Temps are lower now:

@Evv1L in my opinion, it's pointless to even bother with nvidia on t440p/w541. libreboot disables it, and does intel-only for graphics.

the nvidia binary driver is no longer maintained for that one, so you have ot use an old linux distro. there is a hack on AUR that makes it work on newer kernels but it's still proprietary software.

and with the nouveau driver, performance would be about the same as just using intel graphics anyway.

My modded Libreboot 9020 is now available to buy. Same URL:

https://minifree.org/product/libreboot-9020/

Vents cut in top/side of the case (with dust filters). Noctua NH-L9x65 CPU cooler. CPU re-lidded (liquid metal on IHS). Now 90w CPUs run safely; Minifree sells i7-4790k.

32GB RAM + GPU upgrades (AMD Radeon RX 6400 on 9020 SFF and 6600XT on 9020 MT).

Libreboot replaces proprietary BIOS/UEFI. Debian Linux, other distro or BSD at your option e.g. OpenBSD, FreeBSD. I'm Libreboot's lead dev; sales fund Libreboot.
