<p>What I'm looking for is a differential signal tester, where you can breakout any arbitrary cable or traces and test the properties of the wire with different frequencies. It should be able to measure interesting properties such as resistance, capacitance, inductance, phase/length difference, wire length, etc.<p>One of these devices for approximately $100 would sell all day long.</p>

<p>> Those with a bit of silicon savvy would note that it’s not cheap to produce such a chip, yet, I have not raised a dollar of venture capital. I’m also not independently wealthy. So how is this possible?<p>What kind of order of magnitude of cost are we talking about?<p>What are the next steps - is there some service to cut the wafer and put into a package for you?</p>

<p>Exactly this. You calm down, take a cup of coffee, marvel at your beautiful design, and then spot something out of place. The actual review has saved me a few times too, for example: "are you sure there are no copper layers in your PCB design?" - Doh! A few times they have raised issues regarding the limitations of their manufacturing capabilities, and this too has saved time and cost.</p>

<p>To build a Gigawatt AI data center in 2025 is reported to cost $35bn [1]. If you're not going to build it to top specs, why even bother. Given that this is the UK, once all the bureaucracy is done, it'll be at least 50% more expensive.<p>A large business is estimated to use 50MWh at £14,706 a year [2]. It'll cost in excess of £300k per year just to run electricity, not that the grid has that in spare capacity [3]. It's completely in contrast to their green energy campaign.<p>Then, they don't even have any kind of contract actually in place:<p>> Asked about the terms of the contract that Nscale had signed to build the supercomputer by the end of this year, the government did not reply directly. Instead, it said that Nscale’s entire $2.5bn investment was “not a formal contract, rather an intention to commit capital”, and “may well include equipment and capital funding”.<p>There's not enough serious capital invested to get this off of the ground (or even to break ground seemingly). And then there are basic questions, like:<p>1. Why would build a data center that is supposed to create tonnes of jobs, in a location where it costs a lot to employ people?<p>2. Why would you outsource your data center if you live in the US or EU, when there are better options available locally? These data centers sure as hell won't be used by British companies because the government are crushing them with tax.<p>3. The energy cost is far too high compared to locations with nuclear or hydro electricity generation.<p>This whole thing stinks. I think it's a complete and utter lie.<p>[1] <a href="https://uk.investing.com/news/stock-market-news/how-much-does-a-gw-of-data-center-capacity-actually-cost-4329740" rel="nofollow">https://uk.investing.com/news/stock-market-news/how-much-doe...</a><p>[2] <a href="https://www.moneysupermarket.com/gas-and-electricity/business-energy/a/average-uk-business-energy-consumption/" rel="nofollow">https://www.moneysupermarket.com/gas-and-electricity/busines...</a><p>[3] <a href="https://watt-logic.com/2025/01/09/blackouts-near-miss-in-tighest-day-in-gb-electricity-market-since-2011/" rel="nofollow">https://watt-logic.com/2025/01/09/blackouts-near-miss-in-tig...</a></p>

<p>Yesterday - The start (rendering) of a basic voxel editor for generating OBJ and STL files with just the keyboard. To solve 95% of my 3D modelling needs it turns out I likely just need cubes.<p>Today - Parsing a website's HTML (lots of pages, lots of links) to update an RSS feed that accepts filters. Rather than manually checking a website and losing track of what I have or haven't reviewed, the idea is to feed it into an RSS aggregator.</p>

<p>> A Bayesian decision-theoretic agent needs explicit utility functions, cost models, prior distributions, and a formal description of the action space. Every assumption must be stated. Every trade-off must be quantified. This is intellectually honest and practically gruelling. Getting the utility function wrong doesn’t just give you a bad answer; it gives you a confidently optimal answer to the wrong question.<p>I was talking somebody through Bayesian updates the other day. The problem is that if you mess up any part of it, in any way, then the result can be completely garbage. Meanwhile, if you throw some neural network at the problem, it can much better handle noise.<p>> Deep learning’s convenience advantage is the same phenomenon at larger scale. Why specify a prior when you can train on a million examples? Why model uncertainty when you can just make the network bigger? The answers to these questions are good answers, but they require you to care about things the market doesn’t always reward.<p>The answer seems simple to me - sometimes getting an answer is not enough, and you need to understand <i>how</i> an answer was reached. In the age of hallucinations, one can appreciate approaches where hallucinations are impossible.</p>

<p>It was either PCBWay or JLCPCB, but they had a "review window" where it was possible to make changes or cancel an order. They recently switched this to be an automated review, so there was no opportunity for corrections. It could be that the card companies blacklisted them after people started cancelling orders with their credit cards, because their UI stopped supporting the feature.</p>

<p>> In the last week we received ~470000 crash reports, these do not represent all crashes because it's an opt-in system, the real number of crashes will be several times larger.<p>470k crashes in a single week, and this is under-reported! I bet the number of crashes is far higher. My snap Firefox on Ubuntu would lock-up, forcing me to kill it from the system monitor, and this was never reported as a crash.<p>Once upon a time I wrote software for safety critical systems in C/C++, where the code was deployed and expected to work for 10 years (or more) and interact with systems not built yet. Our system could lose power at any time (no battery) and we would have at best 1ms warning.<p>Even if Firefox moves to Rust, it will not resolve these issues. 5% of their crashes could be coming from resource exhaustion, likely mostly RAM - why is this not being checked prior to allocation? 5% of their crashes could be resolved tomorrow if they just checked how much RAM was available prior to trying to allocate it. That accounts for ~23k crashes a week. Madness.<p>With the RAM shortages and 8GB looking like it will remain the entry laptop norm, we need to start thinking more carefully about how software is developed.</p>

<p>I was sitting in a room the other day with a young adult, we were searching for additional algorithm learning materials. They searched in Google, and accept the cookies. They clicked on a website, and accepted those cookies too. They then started entering their email address to access another service. I was completely taken aback.<p>I'm the sort of person that either rejects the cookies, or will use another site entirely to avoid some weird dark-pattern cookie trickery. I don't like the idea of any particular service getting more information than they should.<p>Siting there I realized, we were not the <i>real</i> target. It is the young people that are growing up conditioned to press accept, enter any details asked of them, and to not value their personal data. Sadly, the damage is already done.</p>

<p>> The UK is bracketing "intimate images shared without a victim's consent" along with terror and child sexual abuse material, and demanding that online platforms remove them within two days.<p>Bare in mind, this would have been used to stop the Epstein images of the former Prince Andrew from being viewed [1].<p>> Platforms that do not do so would potentially face fines of 10 percent of "qualifying worldwide income" or have their services blocked in the UK.<p>Why on earth would it be 10% of their world wide income and not their UK-based income? These politicians really think they have more power than they really do.<p>> The amendment follows outrage over the Elon Musk-owned chatbot Grok's willingness to generate nude or sexualized images of people, mainly women and girls, which forced a climbdown earlier this year.<p>The AI didn't just randomly generate NSFW content, it did it at the request of the user. Remember, there was no interest in removing the CP content from Twitter prior to Musk buying it, and then they all moved to Mastodon / BlueSky where they now share that content.<p>> The government said: "Plans are currently being considered by Ofcom for these kinds of images to be treated with the same severity as child sexual abuse and terrorism content, digitally marking them so that any time someone tries to repost them, they will be automatically taken down."<p>Ofcom simply doesn't have this kind of power. 4chan are showing as much [2]. This is simply massive overreach by the UK government, and I would advise tech giants to stop complying.<p>[1] <a href="https://www.bbc.co.uk/news/articles/c4g5490xmkeo" rel="nofollow">https://www.bbc.co.uk/news/articles/c4g5490xmkeo</a><p>[2] <a href="https://www.bbc.co.uk/news/articles/cz6ejedj59no" rel="nofollow">https://www.bbc.co.uk/news/articles/cz6ejedj59no</a></p>
