@JoshFG @NJ_Timothy Ah, the deafening sound of the right and far right being silenced — as may be frequently heard via many media outlets — shall reverberate until the heat death of the universe.

@NJ_Timothy You’re not being silenced you’re being criticised. If you were being silenced you wouldn’t have been able to write a telegraph column about being silenced!

@MehdiHacks And it still uses those horrible cheap mic connectors! I'd want Lemos at that price.

Figures state Doom Bar is the nation’s best selling cask ale! I have always found that amazing. Agreed? 🙄

@travisgoodspeed I love how they illustrated the point with a photo of a luggable that has an orange CRT instead of a plasma display.

I've been wondering about this since the second grade.
Retro Coast@RetroCoast

In the #1980s many portable computers had orange screens. This resulted from a gas plasma technology that was lighter weight than home computer screens.

@treb0r Afraid so. It's pure weapons grade rubbish. We'll just have to agree to disagree.

@MC_chibill @uhf_satcom @MehdiHacks A completely new documentation platform should launch in the coming weeks. The reference platform is Linux, while Windows support is generally bundled with third party apps. Though there is now a Conda environment provided for Lime Suite NG and use with GNU Radio etc.

@9600 @uhf_satcom @MehdiHacks Would have been nice if they updated their shit to actually make us aware it exists, all their Mini pages point towards the old as hell Suite that wants you to install an out date pathos or something. Plus annoying have to build the windows stuff from source for that.

LimeSDR Micro uses an interesting chipset: NXP LA9310 is a programmable baseband processor, that includes many things like a Cortex M4 microcontroller, and a PCIe controller. It sits between the RF part and the PC. It does what usually a FPGA does in such SDRs.

New SDR coming soon! "LimeSDR Micro" is offered in 2 form factors: mPCIe and M2. It has more than 100MHz bandwidth. I got a sample board to test and review. Will share the results here. They will soon launch a campaign on CrowdSupply.

@MC_chibill @uhf_satcom @MehdiHacks Classic Lime Suite doesn't receive so many updates, but Lime Suite NG does and supports Mini v1. Not to mention that it's also supported by the new LiteX-based gateware, which makes it easier to integrate custom h/w acceleration etc. limesdrgw.myriadrf.org

@uhf_satcom @MehdiHacks Plus it sort of seems like they stopped actively supporting the Mini, since all the drivers and software for it are years old.

@rossiadam Worked with and had Sun training for E10K in 1999. We had one of the very first machines. It was a beast! Split into two (domains?) running Sun clustering and Oracle HA, for the boo.com e-commerce backend. Pretty sure they scaled to 64x CPUs.

In 2004 the Sun Fire E25k was the apex predator of computing. This was the largest single-image Unix machine that money could buy ($2M fully loaded). This bad boy had: • 36 UltraSPARC IV processors (72 cores) • 576 GB RAM • 18 fully hot swappable CPU/memory boards • gigabit ethernet and fibre channel HBAs • Redundant power supplies, cooling zones, draw 15kW of power I deployed software to these things. Uptime was measured in years. This was THE ONE. Man I miss Sun.

@memorialdevice The Smokebelch version dedicated to the memory of Ali Cooke is something else — and AFAICT never appeared anywhere else either.

@QVHenkel @mycoliza Are you using JLCPCB for all the other boards in the design? Curious if people are using them for more advanced/challenging designs with stricter constraints.

Thanks to JLCPCB, sourcing a copper core PCB is actually cheaper and faster in low quantity than a plain copper sheet metal with a solderable surface finish😄

@GregNotSure @i2cjak "Closed"? All LimeSDR boards are full open source hardware designs (PCB project and manufacturing files), open source FPGA gateware, open source MCU firmware, and open source host driver stack.

@i2cjak I would still prefer something based out of Pluto+. LimeSDR became too closed and lots of interesting OSS projects don't support it.

The BBC should respond by collaborating with South Park to replace him in all future coverage with their cartoon likeness. I reckon I've got that Director General job in the bag. bbc.co.uk/news/articles/…
