<p>I believe the blocker here is that USBC display support requires getting full Thunderbolt support working. Apple built their own Thunderbolt chips, which diverge from the Intel hardware that everyone else has used & that the Linux kernel drivers are written against enough to make support much harder than you'd expect.<p>IIRC Asahi has finally acquired Thunderbolt support but that support still doesn't have the pieces needed for external displays.</p>

<p>Flipping one card doesn’t change the state of the other one. Measuring the state of one of a pair of entangled particles does change the other one & that change appears to be instantaneous. We know this - Aspect carried out the experiment in the early 80s & those results have been confirmed by later, larger scale experiments.<p>(IIRC It’s possible that a super-deterministic hidden variable system could explain Aspect’s results. But that pretty much requires the universe to deliberately plot against you, which seems very unlikely.)</p>

<p>Quantum effects travel instantaneously in standard QM, no pilot wave required: What’s limited to light speed is /information/.<p>You can entangle two particles in QM, separate them by light years & when you measure the state of one of them you will instantaneously determine the state of the second one, no matter how far away it is. But you cannot transfer information by doing so - information must plod along at light speed between the two.</p>

<p>If the oauth wall is managed by PHP, then it looks like the answer is yes, you’re vulnerable to client connections that haven’t logged in.<p>This looks like a bug in PHP’s assembly of multipart responses & you can feed one of those to the PHP backend with a simple web request, no auth required I think.</p>

<p>Failing to do anything constructive about the problems he’s identified is Cummings’ whole thing though.<p>He’s like an incompetent Cassandra: people keep on agreeing with his diagnoses, giving him power in the hope that he’ll fix things at which point he makes a complete hash of everything and leaves in a huff having made things worse than they were before.<p>If the right ever takes power in the UK in the near-ish future I expect us to go through exactly this cycle again. Cummings seems to be very bad at the politics of driving organisational change & making it stick, which is ironic given that criticising public bodies is what he spends so much of his time doing.</p>

<p>You short pins on the right joycon connection at boot time to enter recovery control mode in the boot firmware which (via an unpatchable exploit) gives you full access to the hardware IIRC.<p>(I presume the picofly & similar devices are just doing this automatically so you can boot the hardware under user control without requiring other hardware to make the exploit work?)</p>

<p>My experience has been that anything less than a 4-bit quant has a tendency to go off the rails. There’s a threshold of coherency that is being crossed somewhere internal to the model I guess.<p>Try the same prompt with a larger quant (even if it runs very slowly because the model no longer fits in VRAM) & see if Qwen does better - if so, there’s your answer.</p>

<p>Most of the Dimensional ETFs seem to be following some kind of value investment strategy where they take an index but nudge it a bit by some value factor which is claimed to be based on long standing research. It wouldn’t be surprising if this value factor has underperformed in recent years which have been dominated by the rise of growth stocks. The video you link to seems to be talking about these ETFs, although I haven’t dived into the numbers.<p>As far as I can tell the straightforward US & world equity ETFs I’m referring to above don’t have this value bias.</p>

<p>Dimensional runs a bunch of ETFs which are effectively US & world equity index trackers that don’t slavishly follow the indices & can therefore avoid being forced to buy into IPOs or index updates. E.g. DFUS is effectively VTI (IIRC) without the requirement to immediately buy into IPOs that are added to the index:<p><pre><code>  https://www.dimensional.com/us-en/funds/dfus/us-equity-market-etf
</code></pre>
I don’t think they have a QQQ equivalent but I haven’t looked at their entire ETF list.<p>(I have no relationship with Dimensional, nor do I invest in these funds - I just saw them mentioned in a YT video on this topic a few months ago: <a href="https://www.youtube.com/watch?v=mqIHa6URUPk" rel="nofollow">https://www.youtube.com/watch?v=mqIHa6URUPk</a> )</p>

<p>This was a laptop, so cooling was very constrained. The fans can only be so big & you can only shift so much air in & out of a MacBook.<p>I presume Apple knew perfectly well but wanted the halo product to sell to those people who will always pay extra for the perceived “top of the line” product. Once Intel branding had created an i9 that was a bigger number than an i7, then Apple was going to sell it.<p>It was faster than the i7 after all: just not for very long!<p>My entirely speculative theory is that the poor thermal characteristics of that era of Intel CPUs didn’t really become apparent until quite late in the development process & by that point Apple had probably committed to buying a fair chunk of Intel’s output.</p>

<p>The i9 was notorious. Would thermally throttle almost instantly & for any sizeable build job would end up slower than the i7 IIRC.<p>Intel really made themselves unpopular with Apple during that period.</p>
