<p>I think you are mistaking "oil" (crude oil) as a straight stand-in for jet fuel. The former is a raw material (one that has a lot of "flavors"), whereas the latter is one possible product from refinement of that raw material. It should be noted that not all refineries are setup to produce jet fuel, and not all crude oil is viable for making jet fuel. I don't know the details about Europe's mix on refineries an d viable crude oil supplies.<p>As it happens, about 75% of Europe's jet fuel comes from the Middle East (I don't immediately have numbers for what of that goes through the Persion Gulf). That percentage puts it outside of the range you can correct with market changes (other than most flights don't fly... that is pretty drastic).</p>

<p>You are correct, but I should point out that Russia has described its Kinzhal missiles as hypersonic, when they are really more of a traditional ballistic missile fired horizontally. So very fast (Mach 10), but not as maneuverable as what the U.S. has been calling hypersonic.<p>Since the original story here does not provide many details, we can't know which side of that fence this falls on (assuming it is real).</p>

<p>At this point no one is talking about using lasers to defend against hyper-sonic missiles (at least not anywhere near the target). All of the current laser systems require being focused on the targets for some amount of time to "burn though", which means they are only suitable for lower-speed targets (drones, cruise missiles, and some low-level ballistics).<p>You would need to have significantly stronger lasers to try and "burn through" on something moving that fast.<p>For completeness I should mention that there was quite some work on trying to get laser defenses against ballistic missiles on their "boost" phase (when they were launching, so slow enough to track a point in the missile), for example George Bush's "Star Wars" defense system. These would have been space based (some of the testing involved mounting on 747s, but I don't think that was ever an end-goal), but never made it near production.</p>

<p>Note that it is wrong to think that David was at a disadvantage. I know that is not how the story is taught today, but slingshot troops of that age we the snipers of their age: very deadly (not at the range of a modern sniper, but...).<p>If the fight between them was started at some distance, the David should have been the expected winner by pretty much everyone on the field. Think "bright a club to a gun fight" sort of vibes.</p>

<p>Back in another part of my career I worked a lot with putting Macs on ActiveDirectory. And there was a common refrain from Apple about bugs in that implementation: "works on 17!".<p>The joke is that Apple owns the 17.x.x.x class-A range on the Internet (they got in early, the also have a second class-B and used to have a second class-B that they gave back), and what engineers were really saying is that they could not reproduce on the AD systems that Apple had setup (lots of times it was because AD had been setup with a .local domain, a real no-no, but it was in Microsoft's training materials as an example at the time...).</p>

<p>We happened to live on the top floor, so I don't have personal experience for the lower floors, but the communication on the (non official) group chat for the building always hinted that any water outages (we had a few non-power issues with the pumps as well) applied to to the whole building. But thinking back that could be an unfounded assumption.</p>

<p>I wonder if this was in an apartment building. We owned a condo in a 5 story (4+1) apartment building and because it was taller than the San Jose water system was built for, our building needed (electric) pumps to provide water pressure to the building (there were tanks on the roof). If we lost power, then we lost water.<p>Now that we have moved to a 2 floor detached home (also in San Jose) we do not have that issue, and everything is gravity fed.</p>

<p>Isn't this exactly what we should want from a market system? If your division in Florida is inefficient, then from the market perspective we should absolutely want competitors to enter the market and crush them.<p>I think the problem is that people have gotten so used to seeing capitalism from the companies' perspective (i.e.: profits good), and forgot that it is supposed to be all about the collective good. So if you think sustained high profits are good... then you have missed the whole point (the market should always be driving them towards near-zero).</p>

<p>I can't find a reference for this, but listening to NPR this morning there was an offhand mention that last month there were significant strikes going on, and that those are now resolved, but showed up in the employment numbers for last month.<p>So that part could just be a blip. The rest seems on-trend.</p>

<p>The rate of warming is a problem (i.e.: it determines what generations of humans are going to see this), but the major problem is the warming itself, or rather the change.<p>We (humanity) have gotten comfortable with the way things are, and a change in that is going to mean that things are going to change for us, and we don't like change. Most of our biggest cities are all close to the coast and will be subject to massive flooding in the next 100 years (if not sooner). Much of those same large population centers are also fairly close to being too hot for general survival (without aggressive AC). Our agriculture is all setup for the temperatures we have now, and the rain patterns we are used to. So we are going to have to change both where we live, and how we grow our food (location and probably strains as well).<p>Global warming is (almost) definitely not going to destroy all life on earth, but many of the forecasts are in extinction-level for most of the large animals. So life in general will continue, and probably humanity (since we are so good at making environment for ourselves), but the (eventual) changes are going to make the world very different, in ways that we are not going to like.</p>

<p>I think the thing to remember is that with interest rates being essentially 0 during the (middle/end of) pandemic that made it really easy for a lot of companies to finance a virtually free checkbook. They were at liberty to try out all sorts of new experiments, virally for free (at that moment).<p>Now those bonds are all coming up for renewal at much higher interest rates, and the companies don't have the growth to organically support the higher head-count (in addition to the interest payments), and so are cutting.<p>Was this all wildly irresponsible? Yes. But the people who made those decision are never going to personally pay for any of it.</p>

<p>I think this is mostly because they don't care about false-negatives. They have forgotten the idea that our justice system was supposed to hold true to: "better a hundred guilty go free than one innocent person suffer" (attributed to Benjamin Franklin).<p>This can be seen in the case of ChongLy Thao, the American citizen (who was born in Laos). This was the man dragged out into freezing temperatures in his underwear after ICE knocked down his door (without a warrant), because they thought two other men (of Thai origin I think) were living there. The ICE agents attitude was that they must be living there, and ChongLy was hiding them. That being wrong does not cost those ICE agents anything, and that is the source of the problems.</p>

<p>This is misleading. While there are privately owned tanks, they are all old, and lack any weapons (other than as a battering ram).<p>They likely could cause a lot of trouble for a local police force, but would not stand up to any infantry force in the world.<p>So in an actual conflict with the U.S. government, none of those tanks would be more than symbolic. And whole a general gorilla insurrection in the U.S. would be nasty, examples like Wako demonstrate that even mid-sized stands would be severely overwhelmed.<p>The whole idea that a Second-Amendment rebellion in the U.S., absent the military joining on the side of the rebellion, is just a fantasy.</p>

<p>I don't think that you understand how that part of statistics works. You are said that we have sampled 64% of the population, so we can extrapolate to the rest. That works if the sampling is sufficiently random. But in this case the "sampling" is people who voted, so an entirely (self) selected population, and pretty much not random at all (i.e.: people who were mostly less decisive about their opinions/vote).<p>So I don't think we can extrapolate confidently at all. So we really don't know whether it holds for the rest of the population at all.</p>

<p>These are being sold on Apple's AppStore, and there the model is that you get all of the updates for that App. Of course there is the work-around that some apps use, which is to create a new App (i.e.: MyApp vs MyApp2), which Apple could do at some point in the future.<p>The best one to watch at the moment is if Pixelmater Pro license holders from before it was bought by Apple get access to any of the new improvements.</p>

<p>I don't agree that it was a "bad management decision". The Trump administration has demonstrated that it will play dirty with grants if they perceive that the receiving organization is not towing their political line as closely as they want.<p>Not only will they not grant future funds, but they have shown that they will not pay out previously agreed monies, and will even try (with government layers) to pull back funds from groups they have decided "do not align with the governments interests", for however they define that at that moment. There are a long list of court findings that these have been arbitrary and capricious, but every one of those findings (wins) cost the grant receivers a lot of money in court and later fees.<p>So any money taken from them is incurring a risk. You can disagree with the Python Foundation's calculus on this (saying it was not that large a risk), but please don't pretend that it was not an actual risk.</p>

<p>My wife's previous job was as an accountant with the endowment foundation at a mid-sized public university (San Jose State University). A lot of her time was spent making sure that the spending from the endowments many different funds corresponded to the rules that the donors had given when donating that money. Much of that was working with groups to shift spending around between accounts when they invariably made "mistakes".<p>One of her biggest projects was shepherding a large group of very old donations through a legal process to remove provisions in the donation agreements that were now illegal. In these cases the donors were long deceased, and the most common rule that needed to be changed was targeting race or ethnicity (e.g.: funds setup to help black people, or Irish, etc...).<p>The sheer number of different variations on "donor intent", or even just the wording on that legal document was astounding. There was always a tension between my wife's group and the group that was bringing in the money ("stewardship"), her group wanted things to be simpler and the "stewarding" group wanted nothing to get in the way of donations. It was remarkably similar to the tensions between sales and engineering in many software firms.</p>

<p>The NeXT (then Apple) product you are talking about is/was WebObjects:
<a href="https://en.wikipedia.org/wiki/WebObjects" rel="nofollow">https://en.wikipedia.org/wiki/WebObjects</a><p>It allowed for both HTML applications and Java apps (both JNLP and completely local). And before the transition to Java it was ObectiveC, and I think even had a scripting language (WebScript?). It was beautiful, fast, and for lots of things you could just wire up a small app to a database with almost no code (then later add the business code after the demo).<p>One of my first jobs was writing a web app using it, and those were fun days.<p>The EnterpriseObjects part (the part that managed data to/from the database) survived for a long time in parts of Apple's web back-end.

<p>This is a longstanding problem.
