<p>We've gotten pretty good at digging holes in the ground and there's a lot of existing energy down there under our land (and near-by water).  So yes, we've certainly had misadventures in the middle east, but we've also embraced the "drill baby drill" mantra of late.<p>Texas is probably our national leader in terms of deploying solar and wind power, which feels ironic but is totally rational and logical.</p>

<p>The most interesting trackers to me, for DIY install in my yard, is a 2-axis tracker.  Especially in summer, sunrise and sunset are quite a bit north of east and west, meaning a true south facing fixed set of panels wouldn't even see the sun yet.<p>Sadly, my investigations a few years back indicated that a suitably strong and robust 2-axis tracker that would withstand our local winds and snow loads is significantly more expensive than just buying more panels and facing some of them east/south/west to accomplish the same thing.  Doing this on an existing shed also avoids some local zoning rules vs a dedicated ground mounted system.</p>

<p>Making production software is still hard.  You still need to know what you're doing.  Making good software still requires significant investment of time and intelligence.<p>Using LLM tools can greatly accelerate development when used effectively, it can enable much smaller high performing teams to be much more effective.  But it's not magic and if you're holding it wrong it really can be a hindrance rather than a benefit.</p>

<p>I can understand that the AI labs might care about other labs distilling their models as it can eat into their competitive advantage, but do consumers care at all?  Aren't consumers benefiting from this practice by getting better cheaper models as a result?</p>

<p>To get memory mapping across systems you'd want to look into infiniband (<a href="https://en.wikipedia.org/wiki/InfiniBand" rel="nofollow">https://en.wikipedia.org/wiki/InfiniBand</a>) but the adapters generally aren't cheap.  Common to find in super computer clusters.<p>If you have a desktop CPU with 2 memory channels and 2 DIMMs per channel, then the 2 DIMMs on each single channel share all of the address and data lines, there's just a chip select difference to pick which DIMM you're addressing.  There is some extra loading on the lines, since you have 2 DIMMs, hence the supported speeds are usually slightly lower, but you only add 1-2 more actual PCB traces to have 2 DIMMs per channel vs 1 DIMM per channel.  In contrast, adding another memory controller would add upwards of almost 100 additional PCB traces from the CPU.</p>

<p>Each memory controller interface is a not-insignificant number of PCB traces.  Increasing the number of memory controllers may dramatically increase the number of PCB layers (or may not, it really depends on the CPU pinout) but it definitely will increase the number of pins on the CPU socket.<p>This is one of the main reasons (the other is the number of PCIe lanes) why high end desktop and server CPUs have like double the number of pins and so much bigger sockets as compared to consumer desktop CPUs.</p>

<p>I’m also watching Intel Celestial with 160GB of LPDDR. Noticed lower memory throughput than AMD or NVIDIA, but potentially significantly lower cost per card. Two of them would likely run deepseek-v4-flash sized models pretty decently.</p>

<p>Trace antennas are very specifically designed shapes given the PCB material and other nearby components and structures. It’s never “just a trace”.<p>You’re right that traces can emit and receive RF, hence why things like FCC limits and testing exist even for unintentional emitters, but even failing devices which greatly exceed the limits have traces which are many orders of magnitude worse at being antennas than a typical trace antenna.</p>

<p>With MoE models like Deepseek’s and with multiple Crescent Island accelerators, the aggregate memory throughput actually doesn’t look that bad. Two Crescent Island gets roughly 1400GB/s and Deepseek-v4-flash with 13B parameters active nets roughly 100t/s which is decent for a small team or great for a single user.<p>More Crescent Island scale up, although not likely entirely linearly.<p>But all GPU inference work like this, it’s not specific to Intel. Just Intel promises more affordable cards with big memory so they’re attractive.</p>

<p>Curious how robust the (what looks like PCIe edge connector slots) connection to the drives is in practice.  Obviously converting from the horizontal mainboard to a vertical drive requires such a connection, making it a plug-in card at least allows for replacing the card if it breaks/wears/etc, and mounting the front of the adapter card to a bulkhead should prevent much shifting of the card in the slot.  Neat design and reuse of a cheap high speed connector.</p>
