@IPngNetworks This looks pretty damn good!
@IPngNetworks Where are you going to use the 14” monitor for? Navigation/map? ATC prompts? Live action photo?
We’re proud to announce that, as of Tuesday evening, the Amsterdam Internet Exchange hit a new peak traffic record of 13 Terabits per second! 🎉 A big thank you to our members and customers for making this possible. We couldn’t have done it without you! 👉 ams-ix.net/ams/news/new-p…
@IPngNetworks Have fun Pim and enjoy your sabbatical! But wait… did I just saw a full blown cockpit in your basement?!
@IPngNetworks Just let me know when I can register! 🤓
@jilles_com Sterkte! Hopelijk komt alles snel goed!🤞💪❤️
@jilles_com @dutchcomiccon Veel plezier!
Wake up Europe, the digital age is bypassing you. You have no Google , Amazon, Meta, Apple. You arrogantly called SpaceX a fanciful dream and it wiped out the European Space Agency. You have no Nvidia and your response to AI has been to regulate before you have anything domestic to regulate. Your car industry is about to be wiped out by the Chinese. Your biggest economy shut down nuclear out of spite and with fraud. Your capital markets have no liquidity and your startups are drowning in bureaucracy. Your border is being attacked by Russia and your defence spending will have to triple just to be where it was with US subsidy given that part of the former Soviet Union and the Eastern bloc is now part of the EU. Your economy has slumped from the world’s largest to way behind the US. Your pensions are paid by three times less people and cost five times as much as people live longer. Your infrastructure is a model for the world but is configured for rail over self drive. Your electricity grid needs half a trillion of investment to cope with planned capacity and replacements, for the switch to renewables, within a decade. There are bright spots such as pharma and your healthcare system is a model for what civilisation looks like it. But to afford it, you need to completely transform from the industrial to digital age, to reform your institutions and rout the sclerotic bureaucratic system.
Anyway speaking of dirigiste failure, here's another banger. Going from calling reusable rockets a dream to not having a space industry in 10 years. Good job guys!
@jilles_com At first glance, I thought it was a soldering iron with a screw bit :)
The xz fiasco has shown how a dependence on unpaid volunteers can cause major problems. Trillion dollar corporations expect free and urgent support from volunteers. @Microsoft @MicrosoftTeams posted on a bug tracker full of volunteers that their issue is "high priority"
@jilles_com @syljil Goed en snel herstel gewenst! Dat draadloos staat je veel beter ;)
Playing snake on @Ubiquiti Etherlighting switch. Most expensive gaming console I own. Game selection is pretty limited due to the poor resolution. They went overkill on ethernet connectivity but forgot about other ports, I can't even plug in my gamepad. But it has RGB. 9/10

@PE1RDP @pe1chl github.com/skuep/AIOC open hardware; je kunt de gerber files bij bijvoorbeeld JLCPCB uploaden en alten fabriceren. Wordt allemaal stuk goedkoper als je meer tegelijk laat maken; vandaar met een grote groep gedaan :) kosten onderaan de streep uiteindelijk; 12.50
