gerdesj··on Compressing a flag to 11 bits
This scheme is OK but not OK. You note the Brazil flag and that's a great example along with the likes of the UK and the US too.

The Brazilian flag is nominally "quite" simple: Green with a yellow/gold parallelogram/rhombus with a blue circle ... then there is the white band and stars. Absolute nightmare to classify.

I thought the UK flag was a bit of a challenge and I remember an art class 50 odd years ago, trying to paint the bloody thing. Little did I know at the time about how Aussies and Kiwi worriers and co would fare! Won't someone think of Hawaiians: their state flag is not something you depict for a quick laugh!

I suppose the US flag is arguably the hardest to depict: Those stars would take ages to draw/paint/dribble. I imagine kids get a box of stars to stick on their depictions in art classes in the US.

A jack is a flag flown from a jackstaff, wot is found at the back of a ship or boat.

The UK flag is called the Union Flag (it's a flag and it is a union of various flags and possibly nations too!) but let's face it, given how many people think its called the Union Jack, it doesn't really matter.

If your flag pole at home is somewhat canted then I think you can call it a jackstaff, with a similar justification to the Royal Navy managing to designate their shore bases as ships. For example just up the road is HMS Heron (His Majesty's Ship: Heron).

The Union Flag/Jack is only the flag of the UK by convention and not law. It's a bit wooley, just like our Constitution but it still all works.

My point is that whilst I do enjoy this encoding scheme and it is jolly clever, reality is way more complicated. The UK's flag is pretty complicated but not alone. I'm pretty sure several flags have tassels, which I suppose strays into the coat of arms territory.

How hard do you want to squint!

gerdesj··on Why is Google still serving dodgy ads?
I suppose the obvious question is: Are you actively profiting from Adsense?

If yes, then ... you are profiting from ... that shite. You must be OK with that and it does sound like you are actively complicit with it, despite your protestations.

If you really think that Adsense is awful and might damage your brand then dump it and don't whine on HN!

OK, that's probably a bit unfair because you are dealing with a monopoly with no recourse to arbitration. That's your real problem.

gerdesj··on AI recursive self-improvement might not come so quickly after all
I lived through roughly the latter half of the cold war and both of my parents were soldiers. I lived in West Germany etc.

No we have not escaped the nuclear thing. If anything, the current Russian tzar is rather more unhinged than any of his predecessors.

I doubt many here know what perestroika and glasnost mean or why those Russian words were so important back in the day.

I don't fear AI (where on earth would an "autonomous" AI manage to find the power requirements). Darleks can't really fly and LLMs will stop when you pull the plug!

I do fear numpties with a red button and a tenuous grip on reality.

gerdesj··on Navier-Stokes Announcement
"I find it really strange the way “peer-reviewed” is used by the general public as some gold standard of truth."

OK but this member of the general public has at least subscribed to New Scientist since 1987, nine O levels, two A levels, two AS levels and a HND in Civ Eng. All pretty mediocre but I have a fair idea on how sciencing is supposed to work and how it ... actually works. Obviously, I ended up in IT.

I should also point out that maths "peer reviewed" is a bit special. For example Mr Wiles went through quite a maelstrom before his proof of some dodgy marginalia was accepted as "true".

gerdesj··on Eating Fruit Skins
Bloody 'eck. This sounds like a chat around the back of the bike sheds off of the '70's onwards.

Yes, apple pips do have a tiny amount of cyanide in them (but why)

This is a from a reasonable source and relates to cherries: https://www.bbc.co.uk/news/uk-england-lancashire-40738573

I think we can assume that apples and cherries are OK to eat. Apple pips are fine and why on earth would you want to crunch through a cherry stone.

gerdesj··on LG denies TV spying claims, says tracking and snooping concerns 'not true'
LG TVs boot Linux and have plenty of capabilities. Why would they not ... take a look around at the environment ... to best enhance ... your errr experience.

LG are amongst equals here. I've seen devices (TVs/cameras) do ping sweeps and then port scans.

I have two VLANs at home: THINGS for IoT and SEWER for things that look really dodgy.

I drive a (Seic) MG4 EV. I use the Home Assistant integration for that and put up with the rest. To be fair I live in the UK and we are quite efficiently ... observed.

I don't normally wear a tin foil hat but you never know!
gerdesj··on Navier-Stokes Announcement
"It's formalized in Lean, isn't it?"

If that's the current burden of proof required in your world for maths then that's fine! 't'ain't in my world: I want to see peer reviewed and published. Surely that's not too much to ask. Its not perfect but generally works rather well for maths.

I'm not a sodding programmer so please don't assume everyone here is one. I'm not a mathematician either but I do have standards: Your counter argument is a poorly constructed and inappropriately deployed example of "proof by whataboutism".

Testing ... testing 1-2-3
gerdesj··on I spent $220 on Google app ads and 60% of the installs were robots
I suggest that Google should be doing that job for you.

It is absolutely ridiculous that you have been either victim shamed, blamed or simply neglected by Google into doing it yourself.

In a mall, you expect to see mall cops ... where are they?

gerdesj··on I'm sorry, you're not going to die from an AI-engineered supervirus
Ye domesday weapon will not be a disenchanted teenager whipping up COVID-19 variants (whatever that means) and spraying them on people.

The real deal needs a lab messing around with viruses and whatever happened a few years ago ... and it did not destroy humanity.

gerdesj··on Microsoft says email spammers are adopting ASCII smuggling
Somehow I manage it for quite a few domains.

You have to do email due-dil and off you trot. Gmail, MS and co really do respect the rules in my estimation and don't simply dump email out of spite.

If you go in with at least everything up to SPF working, you are normally good to go. DKIM and DMARC and all the rest are even better.

I run my own DNS too and am on good terms with upstream so DNSSEC is available. Like I said, it requires some effort but so do most things in life.

gerdesj··on How GPT‑5.6 Sol helps run quantum computing experiments
My C64 is going to absolutely smash this and my dog (Darby) is a frequent barker too! I'll vibe up an abacus emulator as a PWA.
gerdesj··on Leaving VMware just got harder after Broadcom pulled VDDK downloads
I started migrating my customers from VMware a good three years ago.

It does help that I have thirty years Linux experience compared to the paltry twenty five or so of VMware (which was RedHat plus stuff back in day)

I also have rather a lot of Hyper V exposure too and I defy you to love its iSCSI and networking, let alone that awful vTPM thingie.

It's Proxmox for me, any day. Even when I've completely knackered it I can always boot a systemrescuecd and mount and chroot the thing back to life.

gerdesj··on Windows 11's "special" developer edition looks like another marketing misfire
Windows does care about file extensions but is mildly embarrassed about it, hence the "show" default that has existed from Win 8 (?) onwards.

Linux and co generally work with magic bytes which is just another way of doing file formats. Is it better to signify your file format with a .ext or otherwise?

I find myself turning on file extensions if I have to use Windows and on Linux, I don't care and it just works.

I think the UIs for Linux are better. I think that MS are hung up on trying to suggest their stuff so it gets in the way a bit. On Linux, you just get the best option based on what is installed.

gerdesj··on Qwen 3.8 27B available on Cerebras at 1500 tokens/s
Yes, and I said its a limit of the implementation and not the model.

gerdesj··on Qwen 3.8 27B available on Cerebras at 1500 tokens/s
128k context is not a limit of the model, that's a limit of implementation:

"Context Length: 262,144 natively and extensible up to 1,000,000 tokens."

gerdesj··on Qwen 3.8 27B available on Cerebras at 1500 tokens/s
I (we) run Qwen3.8-27B-FP8 on a DGX Spark box - that's roughly £4000 of hardware.

I did benchmark it in various ways and it runs quite well but it is a quantised jobbie and 1.5k t/s is also rather faster than anything I can possibly hope to achieve.

To run that model at those sorts of speeds is going to need some serious investment and you are going to have to pay for it.

gerdesj··on Internet centralization and the original sin of NAT
Mate ... How many people are engineers, technicians, mildly interested, not fussed or call the internet "Facebook"?

IPv4 without NAT was fucked at the design stage. To be fair: Who knew?

I was asked by my employer a while back to investigate this new www thing that has hit the internet (in around 1994 or 5, it took a while to notice) and I said it was a bit crap and no better than WAIS and GOPHER. I was using telnet on a Windows 3.1 PC and telnetting madly via a VAX and a X.25 PAD and what I now know was close to magic!

No one had any idea how things would turn out back then.

I'm actually quite impressed how long IPv4 has managed to work and without NAT (which I do mildly despise, given 30 years messing with this stuff), it would be stuffed.

Thank you for your work.

gerdesj··on I co-founded Burning Man. The festival has lost its soul
Quite right but it would be nice if the kids would invent their own things instead of whining about how expensive doing "boomer things" is nowadays!

Where are your modern alternative festis or something else? Where is the the modern counter culture? What on earth is a counter culture nowadays?

Its fucking doom scrolling shite that my peers dump on you!

gerdesj··on PPWR lands another blow to an precarious tabletop industry
Fuck all. Your point is what exactly?
gerdesj··on PPWR lands another blow to an precarious tabletop industry
The article simply states "we must comply with some regs" and nothing else of substance.

There is no indications of what registration implies nor what packaging is actually required. We get this:

"That’s because one of the primary issues they face is the sheer amount of resources that they need to invest into remaining PPWR compliant."

but no indication of what that means.

This is a whine and whinge piece without any substance. I'm sure there are issues but there is nothing substantive here.

gerdesj··on Black hole singularity is a surface not a point
It was the '80s so safety razor blades were available but in a posh public school (UK version) aged ~17, compasses were everywhere and large old style razor blades were not - the modern style razor with one or two thin blades was a thing. We could have probably got some needles from matron for a finer point, than a compass.

Your pair of razor blades is a great solution.

gerdesj··on Saving 100 terabytes of memory by optimizing 1.1.1.1's DNS cache
Quite. I was a VMware fanboi (25+ years, man and boy)

I still look after a few VMware estates and a lot of Proxmox ones (that used to run VMware).

Hilariously, VMware is described as "enterprise class", which I can only conclude means MVP and a bit wanky.

Today I repaired a Proxmox HA + Ceph node using boring old normal Linux skills and as it turns out I have 30 years of those. Part way through a remote v8 to 9 upgrade I think I lost comms due to using OpenvSwitch for networking and despite using tmux for the upgrade session. Anyway, the Proxmox ISO was useless for rescue but the classic systemrescuecd worked nicely and I could run dpkg in a chroot.

VMware "used" Linux and never really gave back. I don't miss fixing vCentres and all the other nonsense that "Enterprise" wankery has foisted on me over the years.

gerdesj··on An ongoing 3D-printer AGPL violation
Have a look at this: https://ukcalculator.com/barrister-fees-calculator.html

It is for the UK but no doubt m'learned friends in the US can command even higher fees.

Try grabbing a KC for five days, civil/commercial with all the trimmings. That will set you back £105,000.

Obviously the impoverished KC won't pocket all that lolly. There is VAT to pay and staff costs and stuff.

A KC is one of these: https://kcappointments.org/ for obvious reasons they used to known as QCs

gerdesj··on Apple introduces M6 and M5 Ultra
Ubuntu is really polished these days. I rock Kubuntu myself and just migrated my Dad to it from Win 10 (no Win 11 on that box).

I have two members of staff who have asked me to migrate them over. I just need to get "drive mappings" stable and it looks like SMB over QUIC might do the trick.

Canonical show no signs of going evil empire and even if they did there are plenty of options, starting with Debian!
