  1. Energy density isn't actually all that important in a rocket fuel, (To a point anyway). Yes KP-1/LOX slightly outperforms LH2/LOX assuming equally efficient engines at sea level. But get higher up and H/LOX is vastly superior. Throw in a more efficient engine and LH2/LOX wins out by a mile. This is why even the Saturn V's second and third stages are LH2/LOX based. The First stage just fulfils the same role as the SLS's Solid Boosters, get the rest of the rocket high enough for the LH2/LOX combo to get past the drag issues. It's also why some proposals for the liquid Boosters on the
  2. @GDRRiley As someone with a long term interest in space and by extension the craft that go up there. Having 50 odd years of experiance with somthing means jack diddly squat when you put them in a new configuration. There's all kinds of things that can go wrong, the engines vibrations, exhaust flows, and the sound, and Em thrown off by them interact, those interactions have destroyed designs in the past. In theory computer modelling should catch all of that, but well there's a reason they're running these tests. it isn't the things you know that get you, it's the things you thought you know tha
  3. I could speculate but we'd be going fairly far off-topic. But nothing i can think of is good.
  4. The issue is they won't be able to use android or snapdragon processors. Same situation Hauwei is in.
  5. Summary Another round of companies have had restrictions placed on them including for the techies amongst us mobile phone manufacturer Xiaomi Quotes My thoughts Well That Escalated Quickly :p. No to be more serious i don't have a clue what to make of this because with the way the US is at the minute there's no way to tell if these will even stick around very long. So in the short term i don't know what to make of it besides silly meming. Long term if it does stick and they can't get the necessary permits it's going to flatten another major player in the sma
  6. Sadly as LPL, (and another channel i watch, BosnianBill), show the general rule of thumb is that the better the electronic portion of a smart lock, the worse the physical security, and vice versa. From memory i don't think I've seen either review one that wasn't complete usless junk in one way or another.the issue tends to be lack of institutional experiance in one of the fields, so they make very basic security error's, (for example smart locked items that can be disassembled whilst locked), that even Masterlock manages to avoid, (and thats a really low bar, they routinely make mistakes the L
  7. Chiplets shouldn't add much to it, and they actually save a lot. remember the bulk of the silicon volume is in the IO Die and thats on a different higher production volume process, (in part because this stuff doesn't shrink down or get more power efficient on smaller nodes). That plus fewer dies thrown away at the end due to fewer having a killer defect doubtless means more actual CPU's per wafer.
  8. To be fair you only have to watch a few LockpickingLawyer videos on master-lock products to realise even some security companies don't care about actual security. For the curious a General Channel Link. And an example of him opening 11 different masterlock products with the same security flaw in less than 4 minutes.
  9. Agreed, the last thing TSMC wants is to be constrained to one other company. They're not going to let one player put the other out of business generally, it hurts them in the long run too much.
  10. I don't think the initial comments that started that thread where meant that way. My own reaction to the thread title amounted to A) You have got to be kidding me that can't really be a thing), B) Who would be so dumb as to use a device like this for that purpose. People who want to use a chastity cage, not my thing but not a problem for me eitheir if people want to, more power to them. An IoT device for it though is just asking for trouble. I'm pretty sure legal codes require some kind of manual override. Probably also "Fail Safe" as the default.
  11. Already done some time ago. It's a process node issue and any changes Swan made there, even if he made them the day he became CEO, won't be visible for several more years.
  12. To add to this the new guy came up the Intel technical side at the same time as the people there running things did and they're the one's who dropped the ball and got Intel in this mess. That or the people above them, (i.e. the new guy back when he was CTO), did. Either way it's not a ringing endorsement. Hard to say. One way or another it's a showmanship move not a practical one. Swan wasn't there long enough to actually do anything which means there's no real basis for getting rid of him on factual grounds. But much like their new CPU launch it's about appearances to sh
  13. Disclaimer. I'm from Europe, and beyond a strong degree of "A pox on both your houses" sentiment towards both sides in the US right now i have no personal stake in this. What Parler was actually like overall is irrelevant. What matters is was there visible content of the types cited against which parler was taking no moderation action? If so then thats all the reason that Apple, Google, and Amazon need to stop supporting it. Doesn't matter if it was a few crazies only, it's still all the reason they need to take action.
  14. While i get what your saying there, and somewhat agree, it's still the case that we have an example of a digital wallet asking for a level of info, (they wanted more than just this), that i'd expect from a bank or government agency. Thats not a good thing to be doing and it sets a bad precedent. As another example of this effect. The whole reason the early phishing scams where so effective wasn't just human idocy. It was because the internet was a wild west in terms of type and nature of e-mail communications so a lot of them where asking reasonable things for the time they happened in. The ch
  15. Eh i had paypal ask me for a lot more several years ago. Which was why i stopped using them. Your right it's somthing that shouldn't happen but when you've got legitimate mainstream sites doing it your going to see this kind of stupidity
