Same with Google. I searched a covid-related question, and Google's preferred answer at the top was "There is no evidence of this", while the next two links were medical journals that did show evidence that directly contradicted Google's statement.

Rather, I believe it will result in the remaining 20% being held by a few exchanges, whose endgame will be to still charge the fees but just balance them internally without actually costing anything.
The TI-89 comes with a excellent symbolic solver that can do solve this or any calc problem and give the proper symbolic result. It can even do things like equation simplification and give the results in terms of the variables. Looks like this https://imgur.com/a/FmdCyYU
Saying any calc problem is a stretch. Just pull up the MIT integration bee and see how many the 89 can get symbolic results for.
I think the 89 is awesome for algebra because typing in an equation and doing an ans(1) with an operation will let you do the algebra process without making stupid arithmetic mistakes. I wish someone made a calculator that does this only and not one that does all the other CAS tricks for integration and derivatives. Oh and I wish they would make it RPN but that is a whole other story.
Not really. His team paid the price of carrying the burden of his laziness/treachery for a year. If they hired a competent person, they would have been better off.
Exactly. He was taking advantage of everyone around him to enrich himself. The companies were fine (most caught on quickly and fired him) but he left a mark on the teams he left behind.
There’s nothing heroic about joining a team and then sabotaging their work.
There's the "gives everything up for the company, no questions asked" types of people. Tesla et al come to mind for companies that like to hire this type. I don't get that to be honest. Your family and life are not worth whatever they're paying you, even if the work is 'fun' and engaging. YMMV as always.
Then there's the opposite end which you're alluding to but I'm not entirely sure where on the gradient you are. The slackers or someone like the guy described by the OP. I had someone like that recently. I caught it within the probation period and he was gone after 2 months.
Then there's what I would consider the proper position on the gradient line. You do your work, you do your best, every day without question or being 'made' to. But in return you ask for the company to be reasonable too. Proper pay and benefits, flexibility, nice perks but not the kinds of 'perks' that are just designed to make you 'live' at the office, mandatory 'fun' etc. No BS 'do this yesterday because I say so' requests. The list goes on.
There are companies out there, that are close enough to that/let you do that if you don't just say yes to everything :)
>Tesla et al come to mind for companies that like to hire this type. I don't get that to be honest. Your family and life are not worth whatever they're paying you, even if the work is 'fun' and engaging. YMMV as always.
On the other hand these companies are producing some great results. I religiously watch the teardown analysis of the Tesla cars vs others like the Ford Mach-E and the Tesla is just so much better designed in pretty much every regard(except things that require slow methodological improvement such as fit and finish). Whats more, all the Musk companies are moving at the speed of thought. They are so much faster in implementing any new innovation that any competitor makes that they dont have and incorporate it into their product faster than any other company does.

Don't you think these companies are going to eventually be eaten by the companies that have the demanding work environment? For better or worse all else being equal, those companies get more done in the same amount of time.
I am experiencing this at my company, an old bloated payroll company. They have superb work life balance, I get my work done but I know the company is sinking to Silicon Valley rivals, its just a matter of time. The product is old and competitors are just doing a better job. Im currently in a dilemma where I get paid fairly well but not doing any advanced projects, that will bite me long term but the freedom and 0 stress is just so good. I get my stuff done and have time to take hour long breaks.
The kinds of people that work at such companies I am very very sure would do great things regardless. In fact, I know quite a few people like that, some of which I work with, which is awesome. It's like finally finding your true 'home' company wise, when you have that feeling that your are mostly working with people that both know their stuff and just want to do great work together.
In my book there's a huge difference in whether you have your own company for example and you work on something you love with other like minded people in every free minute you have. But when your kid is sick and needs to be fetched from daycare and mommy has an important meeting to attend it is absolute clear that you won't be working and instead driving to the daycare and nobody even blinks an eye at that and there's no bad feelings on your end, worrying what people might think. Of course you will take care of your kid. And no you won't be working all weekend long just because some sales guy promised the moon to a customer, you will actually be playing with your daughter. Some days you will work 10 hours because you just want to finish that one thing as you're on a roll or there's a Prod incident or something and your SO has got your back. Friday after you definitely go home early and enjoy the weekend. What's not OK is for some VP to have dragged his feet on something and when he remembers about that important presentation the next day he tells you to "get him those numbers by EOD or else".
The proper point on the gradient that I like is definitely _not_ the old bloated payroll company you are referencing. I think that sounds like the kind of company that has tolerated a probably >90% slacker population for way too long and I would be miserable, because I'd constantly ask myself why those guys get paid to be on Facebook all day or pretend that adjusting the background color of that button takes a whole sprint. Taking hours and hours of breaks and nobody blinks an eye is absolutely not OK at all. That's not "You do your work, you do your best, every day without question or being 'made' to". Absolutely that company _should_ get eaten.

This is not what I am talking about. Yes brilliant people are a prerequisite but I am referring to squeezing them hard to get that extra improvement out of them. You see it in the Tesla car vs something like the new Ford. They are both good cars clearly made by talented people. But then when you tear down the Ford you see how the battery pack is made in a manner where they didn't wring out every extraneous cost and they didn't squeeze every last bit of potential out of it. There is so much room for improvement compared to the Tesla. It seems as if Tesla just forces their people to burn 100 hours weeks all the time just for that little extra that ends up in their end product.
>or pretend that adjusting the background color of that button takes a whole sprint.
Im actually in that position right now getting paid 100k. It is depressing as I am wasting my late 20s early 30s but at the same time I see people like Elon getting insanely rich while so many people in the country are sinking beyond salvation. He is actually getting rich off not only the backs of the people he overworks but the parents that raised and invested in those people and the local communities that spent decades molding those people. And what happens in the end? He burns them out and replaces them with new blood.
It makes me realize that 95% of this tech stuff is BS and the few jobs that actually have some innovation are locked behind gates or require sacrificing everything else to achieve. If you are not naturally gifted to be in the top 5% then it is just not worth sacrificing everything else. I guess thats why companies like mine end up filled with people who take a whole sprint to change the background color. There is so much money floating around these companies that are all majority owned by a few mutual funds anyway that its downright stupid not to take as much as you can from them while you can.
$9.5 billion over is pocket change! If you adjust for inflation $10 billion is only $7.7 billion in 2007 dollars. Assuming the telescope works I can live with it being expensive.
Unfortunately, I think it's easier to fund something like the F-35 because it can be framed as a way to avoid an existential threat. It's difficult to do the same with fundamental science
That argument only holds because it was purported to replace different weapons systems that were needed for mitigating a threat. The threat is the primary motivation and cost reduction is secondary. I.e., if not but for the existential threat there's no need for the JSF or any system it would replace.
The F-22 was sufficient for threat mitigation. The F-35 raison d'être was cost reduction, after that was exportability which again was supposed to help with cost reduction.
Edit; comparing the logic of a 'but for' vs a 'necessary' condition. Was the F-35 necessary for threat mitigation. No. Was it framed as the necessary for cost savings, yes.
Your oversimplifying and missing a lot. The F-35 is not a replacement or substitute for the F-22.
The F-22 is an air superiority fighter. The F-35 is a multi role strike aircraft. The F-22 would never be allowed for export, because it has features we don't want to share even with allies. The F-35 was designed for export to allies from day one.
There's no scenario where just buying more F-22's made more sense than building the F-35. The F-35's project problems, primarily driven from the joint acquisition strategy are their own thing, completely independent of the F-22.
The F-35's problems as I understand it stem principally from the Navy wanting a VTOL craft. That whole system seems to be front and center when "stuff not working" comes up.
Marines not Navy, though they're a sub org of the Navy so a reasonable thing to say.
There's a Rand study on it. They concluded that the attempts at commonality didn't just fail, they proved counterproductive. They did a historical review of joint acquisition programs and found basically all of them hit the same flaw. As appealing as it may seem to congress, it's a bad strategy.
The F-35's problems as far as budget and schedule slippage were largely in the software section, and a lot of that goes back to structuring it as a single source cost plus contract. That incentivized LM to make the project as big and delayed as possible.
LM is infamous for this sort of thing. They turned Aegis into a clown circus of a billion different ship specific variants where they could charge N times to fix the same flaw in different nearly identical codebases. The Navy has been trying to extract themselves from it for like 2 decades now, with some signs of success finally showing up.
In short, LM is behaving in bad faith. This is unsurprising. They basically invented these tactics some decades back.
Back when Ash Carter was Sec Def, he called in LM and demanded they start hitting the promised numbers on marginal airframe costs. Reportedly the conversation went something like "do this or we'll curtail our buy" to which LM responded "by how much?" As replied "how about none?"
Suddenly they started hitting the numbers, surprise surprise.
We're about to have the same conversation about sustainment costs. I hope Austin drives as hard a bargain.
If you've read any of the limited info coming out about some of the AF's new projects like the B-21 or NGAD, it's pretty clear they took the lessons from the F-35 to heart and are using a very different approach, one where they hold the reigns of integration and can create competition at any time.
Their designed for slightly different roles. The F-35’s R&D looks hard to justify vs simply having more F-22, but the F-35B can do verticals takeoff for example and the F-22 can’t.
So, the real question is if the F-35’s should have had fewer versions and thus been more capable in it’s remaining roles.
There's similar analogies here to the space shuttle.
For the shuttle to get approved, it had to meet the demands of many masters. The fact that it had to meet DoD missions as well as NASA missions made it a bit of a boondoggle. Likewise, the JSF needed to meet the Marine Corps demands of VTOL to take the place of the AV8B.
It's hard to remain focused when you have so many stakeholders. As the saying goes, a camel is a horse designed by committee.
The space shuttle wasn't as bad as its reputation though. Both accidents had organizational causes and were entirely avoidable. And its huge payload bay and the fact it was a mobile base allowed for the construction of the ISS.
It just failed at reusability, it was more like refurbishability :) But many lessons have been learned from that.
I'm speaking more to the shuttle cost overruns, both in design and mission. I'd argue that the reusability aspect was central to the idea of a "shuttle" and if it failed at that, it missed its mark.
I agree 100% that there are organizational causes to past mishaps. As to whether or not it was avoidable...I tend to think they are rooted very much in human psychology and we think about risk. The same issues occur today within NASA (EVA 23 is a good example [1], despite the 'organizational' fixes put in place after Challenger and Columbia). Humans are really, really good at rationalizing the answer we emotionally want.
It has a thrust-to-weight ratio > 1, but it can't really take off vertically in the same sense as the AV8B or the JSF. The F22 still needs some appreciable runway so it's really a "short takeoff". I think the thrust vectoring maxes out around 25 degrees, where the JSF can be configured to 90 degrees.
>Was the F-35 necessary for threat mitigation. No. Was it framed as the necessary for cost savings, yes.
I think we're saying the same thing. The argument is, "Was the F22/F18/Fwhatever/weapon-system necessary for threat mitigation? Yes."
With that said, if proponents of the F35 want to frame it as "threat reduction + cost savings" that's how they get the budget approved. But the point stands that without a threat, there's no basis for the cost savings argument. I'm not saying it was effective as cost reduction.
To circle back to the original point, it's much easier to get a budget approved when the basis is existential threat, rather than "science is cool."
I don’t think it’s a great example of using existential threat for sales, when the whole thing was sold as a cost saving. Pretty much everyone at the time just wanted more F-22s. I was a technical advisor on the project.
>I don’t think it’s a great example of using existential threat for sales, when the whole thing was sold as a cost saving.
Again, if there is no threat (perceived or real), there is no need for a weapons system, period. Think of it this way, if there was a proposal for a cost savings for an anti-spacecraft/anti-asteroid system mounted to the JWST? I'm saying no, because there is no credible threat that would prevent. You need the threat first, in order for the cost savings of a program to have meaning if the basis of the program is threat mitigation.
>Pretty much everyone at the time just wanted more F-22s
Not really, unless you're only talking about a specific branch. Only the Air Force wanted F22s. As was stated by another commenter, the JSF was needed because it was because it fulfilled desires that other services had that the F22 does not provide.
Threat mitigation is largely nuclear shield; but if you’re taking about maintaining air superiority then the F-22 is where it is at. The Navy carrier fleets and Marines are force projection.
The JSF were sold around cost savings; half the price so you could buy twice as many.
I think you're taking a very narrow definition of what a threat means to make your point. To a Marine in Afghanistan, the threat was not mitigated by a nuclear arsenal. To them, close air support from a technologically inferior aircraft like the A10 did a better job of eliminating a threat than the F22 in many instances. To the original point, this is why it became difficult to retire the old plane despite the JSF and F22. It could be tied to a specific threat, and that meant it was politically much easier to defend keeping it around even if the business case was that it costs too much money. At the end of the day, politically defending a budget is much easier if it can be concretely tied to a credible risk.
It was canceled because the Navy said it wouldn't work, both because of cost and take-off weight of the proposed Naval variant relative to the capacity of then-current and in-development carriers.
Yes, if you prefer eye candy photos to public safety. By the way will James Webb wield a modern eye candy capable sensor? Not sure about that.
There is few worth from remote sensing unreachable (even in theory) objects. Kepler already proved theoretized Goldilocks Zone rocky planets and, in general, provided a lot of data for non-field research (less exciting than Hubble photos indeed). Last, but not least, what's the JWST's mission exactly?
Also, from taxpayers' money perspective Kepler's component quality was complete disaster.
So, I'd better invest in more Martian/Jovian probes than in revival of obsoleted project. Such revival is very similar to Russian GLONASS (a competitor to 1970s NAVSTAR) programme reboot.
The JWST's mission is to see deep infared, which can pass through interstellar clouds. It will uncover things that have been veiled to us since the beginning of history. It can only be built as a space telescope because the frequency of its intended observations are so low that to a device sensitive to them, air radiates light of blinding intensity.
There is a long list of scientists that know exactly what research they are doing on JWST down to the minute [0]
For example, Dr Christine Chen et al will be using JWST for at least 34.9 hours to study the Icy Kuiper Belts in Exoplanetary Systems using near infrared spectroscopy [1]
Yeah, I read that, just not impressed by minor projects with low outcome. It roughly equal to routine PhD-tier experiments done on the accelerator at some provincial lab.
Just look at breakthrough chances from, for example, 5 days trans-neptunian object search or the pointing of instrument at largely unexplored Uranus system for petty 30 hours.
I hate how shortsighted these comments tend to be, but I can understand them.
The money for projects like this, largely due to the sensitive nature of it all, still ends up staying local to the governments funding the projects, which means a significant minority of it still gets recouped in taxes two or three degrees down, and the balance that can't be recouped still ends up funding colossal technological advances, e.g advances in EM sensors, lensing, computing, electronic resiliency, power generation, the list goes on.
The reason governments spend on projects like this regardless of public opinion is because they're necessary to advance the state of science and engineeeing when investment returns are out of the question near-term.
Even defense spending operates this way, though the degree to which we pour good money after bad in defense is probably worth scrutiny. At least JWST will bring value, unlike the f35.
Well, all the tech advances brought by doing R&D of JWST happened already ~15 years ago and already are at the market. But its just the same thing as with R&D done for F-35. With notable exception F-35's R&D is still work in progress because of upgrades, while JWST will remain a piece of late 2000s tech to be taken out of the attic in early 2020.
Another important point to consider is that by having these big projects you maintain the ability to do them, capabilities need to be maintained by exercising them.
It's roughly the same costs as Hubble ($9.3 billion in 2020 USD), and that excludes the costs for the mirror correction they had to do.
It seems clear the original estimate of $500 million was overly optimistic; actually, it was criticized almost immediately as such after publication. There's a lot of incentive to low-ball these initial cost estimates.
This looks fantastic and I'll dive into this more when work abates. Meanwhile, I'm curious if the visual/diagramming framework for the Enso language (on this page: https://enso.org/language ) is open source as well somewhere?
I disagree. FOSS and commercially licensed (and sold) software with EULAs are two very different things, and can be distinguished in whatever legal language implements these theoretical liabilities
Well, why not shove it all into L2 cache and leapfrog RAM?
