Except "loitering and picking targets" isn't how Close Air Support is being done these days anyway. It introduces too much risk, because there is always the "fog of war" and confusion on the battlefield. If your pilots are picking targets with the Mk1 Eyeball, there is a decent chance they will pick friendly forces, or civilians, by accident.

That's why we are moving to digitally-aided CAS and precision munitions. Of course, if we get in fight with the Chinese or Russians GPS will be jammed to Hell, so that needs to be taken into account too...
Or Google Data Studio.
- z (Linux): https://github.com/rupa/z builds a database of every folder I ever go to on the command-line and uses fuzzy search to open the most likely folder when I give z any string argument. It's been such a huge improvement for my CLI workflow. I no longer need to traverse entire directories if I've been there before. I just need to enter the shortest possible part of the path that'll take me to my destination, often just a couple of characters.

- chocolatey (Windows): https://chocolatey.org/ Package manager for Windows which means I only rarely need to manually download and install programs anymore. I can even tell it to update all installed programs, which is a decent time saver.

Along with what you've described, which covers a huge swath of the problems I found with observables is this:

There is a pretty huge documentation problem with observables.
I originally thought this comment deserved downvoting, because "we'll just print money" shows a lack of understanding about the role fiat currency plays in an economy. However, I realized that this comment is a valuable addition to the discussion, because it expresses an increasingly common misconception.

So thanks for posting it.

Yes, the nation can just print money, but will anyone accept it?

When the supply of money increases, but economic output and resources are held constant, prices increase.

Imagine if the resources available in the economy are worth M currency. If the government just creates 10M currency, that doesn't mean more things are available to buy, just that each unit of currency is now only worth 1/10 of what it was before, so prices rise. But because people expect that, they try to get rid of the currency even faster, so prices rise even more than the increase in the money supply.

This results in "hyperinflation" - prices rising more than 50% per _month_ - see https://en.wikipedia.org/wiki/Hyperinflation for accounts of governments who have tried the "create and allocate currency" approach.

There's a great "Planet Money" episode on the hyperinflation of Brazil, which started when the country decided they could just print money to build a beautiful new capital city, and how it persisted for decades because it destroyed people's faith in the currency as a store of value, until Brazil created a new stable currency and convinced people they would no longer just print money to spend. https://www.npr.org/sections/money/2010/10/01/130267274/the-...

> Me too :-)

I am pleasantly surprised. Always nice to see people who have made such a transition.

I agree with you on all points here. Once in production, stability is achieved and car companies certainly do not hold all the secrets to resource allocation and administrative approaches to healthcare.

The degree of unpredictability is higher in software and medical procedures.
The supply chain - production approach can only get so far.

That being said, the production approach can work splendidly well for low risk diagnoses. The production approach has already been adopted by some software companies. Especially contract based companies that involve a well defined repetitive grind and set of tools. Think developing a Cash-of-clans like mobile game or making websites for certain organizations. Both industries are quite mature. The software problem isn't interesting, but it also rarely throws curve balls.

I am going on a slight tangent, but here goes.

I think there are some medical low hanging fruits. This is especially true in the US, where the escalation of service is extreme. Either you get no service or a $200/hr medical expert.
If the disease is going to be a low risk common illness 95% of the time, then maybe the patient could go through a $40/hr medical practitioner whose job would be to attends to 'easy' cases and only escalates it to the $200/hr doctor if the case is serious enough.
A similar case applies to the ER and ambulances too. There is, "I am about to die" emergency and then there is the "I am hurt, but 20 more minutes to the hospital in car won't change much" type of emergency.

Off topic: But, This approach is quite similar to a popular ML approach called Cascade Classifiers used for resource efficient applications. It is apt, that it would come up in a discussion about how to make Healthcare more resource efficient.

Lastly, I find the requirement of 4 year college to enter medical school to be preposterous. It is a waste of money and time for applicants and serves only to line pockets of academic institutions.
Totally agree with this. I've been saying for at least 10 years that Software Engineer should be a trade not something you go to university for. If you want to be a researcher then academia is the right path, but if you want to build software a trade program / apprenticeship would be much more effective imo.

I've interviewed 100s of university grads and most of them don't know how to actually do anything useful. They have the foundations to grow into the position, but they certainly need someone to hold their hand for a while.

One great example is IBEW electricians. They do a 5 year program. 6 months class room, 6 months on a job site as an apprentice applying the skills learned. Repeat for 5 years with gradual pay raises until you hit journeyman and it jumps up to full union scale.

I think the exact same type of program would work GREAT for software engineering. Learning for 4 months in a vacuum and THEN working in the industry for the first time is a terrible idea. However, doing 6 months back and forth would allow you to apply what you learn and more importantly to learn what you don't know so you can focus on those things during the classroom segments.
The more I understand about science actually works, the more I can't see any reason for someone from 18th century or before not to believe in magic. Especially if he actually did experiments that would confirm this kind of connection - alchemist theories just look like the most logical explanation of such phenomena. (If you don't believe me, just ask Newton).
Of coursemodern universities are a scam. Maybe that's not true for a small % of students (those going into academia, for example), but in reality I'd wager all my money that the majority of students would not end up better in life attending university than doing sef learning online.

Most students don't build a big social network in college. Most students don't take away meaninful thoughts from university. Most students probably don't even end up using the discipline or domain knowledge they acquired for a significant part of their career.

If all universities produce for people is a piece of paper that says "this person MIGHT be able to do the job you want done" (and let's be real - how many people do you know got a college level job simply by flashing their degree?) then there's absolutely no reason that degree comes with a 6 figure debt. That's something we can cut down to low 5 digits easily. The problem of course is universities only have the incentive to charge more for the same product because no one's demanding they do anything of value.
Go has not displaced anything around here.

Still plain old Java, .NET and C++ as always.
Yes it can. If you see a product that claims to be secure, with multiple layers of security, certain exceptionally-fragile measures should decrease how much you believe that claim. Layers of security have to at least be mildly effective to count as layers.

If you're fighting an active attack you can stall by filtering on some arbitrary parameter unrelated to the actual problem. For anything that's supposed to last more than an hour, it's worse than useless. It makes your system more complex for no security benefit. An idea like that should never make it into a product release.
> The problem is, it isn't at all unlikely that a quicksort implementation created entirely independently w/o plagiarizing will match an implementation somewhere online.

It's practically guaranteed. Quicksort is quicksort. You can't get creative with it without implementing something which isn't quicksort anymore. That code may well sort a list, but if the assignment is to implement quicksort, you've failed at the task.

> I think the real fail here is a company assigning something like quicksort and expecting to get original answers.

Right. You have to go to IOCCC levels of perversity to be able to turn in something which is quicksort but isn't going to trip a well-trained plagiarism detector.
The censorship by private organizations would not be a problem if...
> the idea that something so expensive and complicated could be considered one-use disposable is amazing

So much about the Cold War era makes more sense if you keep in mind that a big part of the US strategy was to turn it into a cash-burning contest in which the Soviets would go broke first. The waste was the point!

Clearly this depends on the degree field, and the job.

Just because some company has now decided minimum wage jobs should require a degree doesn’t mean a degree is valueless, it simply a stupid requirement (like requiring 10 years of nosql experience or whatever).

And yes, there are degrees that have much lower economic value - and it’s an idiosyncrasy of design that leads to identical costs.

But there are real cases where degrees matter. For example large scale engineering - you want to employ people who know what they’re doing at a very core level. So they need to have been taught those skills, and they need to have a way of showing that they have been taught them, and that they actually did learn: a degree.

For many things apprenticeships would also work, but note that most apprenticeships do result in pieces of paper (journeyman, etc).

Do I think my CS degrees are necessary in of itself? No. But I learned a lot while getting it, so it’s nice to have an public record of that.
If the chart presented in the article below [1] is fairly accurate and not merely representational, I think that the 737 MAX, without MCAS, does not actually become statically unstable in pitch at least until after the stall, but the response was still unacceptable, and the reason MCAS was needed for certification.

There is a complication here in that the stick forces are generated by an elevator Feel and Centering Unit, which is fed by a dedicated pitot tube and the stabilizer position.

Pitch instability after the stall was part of the rear-engined jet deep stall problem, and the reason for stick pushers [2].

Why would I want to be at the end of the food chain, owning a money losing taxi company? What's unique to Lyft, are there at least signs of profitability given the pressure from competition?
I wonder if there is a good way to test for this, and if it affects humans.

Kambo[0] is a medicine extracted from the South American Phyllomedusa Bicolour[1] tree frog that is used by humans, I believe without any processing. (As if it weren't dangerous enough already...!). I hope practitioners (e.g. the IAKP[2] take note) can come up with a way to test before using it.

Looking at degrees in the US, IIRC, the shift did happen in the mid/late 80s. I have no idea what might have caused it, but basically the male/female ratio was pretty consistent until then, when male degrees suddenly skyrocketed while female rose slowly, at a pace very closely in line with the previous pattern.

Engineering had a perfectly good solution - a warning system that lets the crew know when the AoA sensors were out of whack.

Unfortunately, somebody else decided to make it optional equipment. And some airlines decided not to pay for it.

So uh, tell us how this was an engineering problem, exactly?
There is that but also access to spare parts. Louis Rossman talks about how it’s hard to get replacement chips to fix motherboards because Apple locks down the distribution channels so they have to relay on harvested components from failed boards or chips who fell of the back off a truck.
Interesting. There is this very relevant paragraph which makes the immunity rather moot.

However, evidential immunity under s 6DD doesn’t protect clients (who have been compelled to give evidence to the Royal Commission) from a regulator, such as ASIC, using their evidence as a springboard to gather secondary or derivative evidence, and using that derivative evidence against them.
Sure it would "save costs".....until we get in a shooting war with China and they stop sending us spare parts. Or given concerns about backdoors in Huawei gear, you can be damned sure they would put hardware-level backdoors in fighter jet control systems. So the cost-benefit analysis needs to take into account the degradation of your security posture that comes from having your greatest adversary supplying your equipment.
Looks like Uber would be a $90B - $120B valuation, so about ~1/4th of Uber.

Uber has ~15 millions daily trips, while Lyft has ~2 million daily trips.
Slack has a network effect for any user that is part of more than one group. If it's just one group for work, sure, the company could switch and gone is the user. But if that user is part of other groups they will push back against the switch as no one wants more chat windows.
I'm also worried about this rash of IPOs not going well. I wondered if that's why so many companies are suddenly pushing for IPO on a tight deadline, after Uber announced. Once one big unicorn tanks after IPO, future IPOs will probably go poorly.
Can you point me to a reference for that? I can't find it anywhere, and didn't know the word relating to anything other than tailors.

Measure that make it harder (but not impossible) for users to disassemble their devices serves to avoid people doing accidental damage (and voiding their warrantee). It's possible to get a pentalobe screwdriver, and anyone not willing to get one probably has no business opening up an Apple product.
I learnt plenty in my CS courses. I just don’t use most of them, and most of the skills I do use I didn’t learn there. That does not mean it was a waste of time - knowing the theory behind various data structures, algorithms, and circuitry make programming more satisfying for me.
I can share my story. I am a first generation student that applied to in-state universities in CA. When I got the acceptance package I got sticker shock when I saw the cost of attendance nearing $40,000. I didn't know how things worked and I didn't know how to navigate the system nor who to talk to. My reaction was one of aversion, I can't go into such large debt. Loans can cover anything, but I don't know how to be in debt, I always paid for everything up front. So I went somewhere cheaper that I felt I could afford.

In retrospect, someone that knew about this stuff would have told me that I could have received better financial aid, and I was probably misinterpreting some of the financial numbers. I mean, I was on my own, an 18 year old kid that was jumping into a scary world of getting into debt. I don't want none of that, give me something affordable.
My guess is that the paper scaters the light, so the image can bounce on the scanner's mirror, even with a small offset. The mirror, on other hand, reflects in a coherent way, so the light doesn't hit the scanner's reflector.
Ah yes, timing the market! Always a good plan!
SEA-PDX by train = ~3.5 hours, ~$50, with a low chance of delays, although if you are delayed, it will likely be for 1 or more hours. Trains leave ~6 times per day or so.

SEA-PDX by air = ~50 mins, $90, with a low chance of delays, and those delays add ~10-20 mins usually. Flights leave ~20+ times per day.

If Amtrak can't get the corridor between these two cities to a competitive state, why would I ever bother with them on a more serious trip?
The S-1 is a bit opaque as it doesn't list out Class B ownership in the table. Lyft class B's are convertible to Class A at any time. If you follow to the table footnote for Green's entry you'll see:

"Consists of (i) 4,663,809 shares of Class B common stock held by El Trust dated August 3, 2015, for which Mr. Green serves as trustee, (ii) 675,564 shares of Class B common stock held by The Green 2014 Irrevocable Trust dated June 12, 2014, for which Mr. Zimmer serves as trustee, (iii) 360,979 shares of Class B common stock held by The Logan Green 2016 Annuity Trust, for which Mr. Green serves as trustee, (iv) 360,979 shares of Class B common stock held by The Eva Green 2016 Annuity Trust, for which Mr. Green’s spouse serves as trustee, (v) shares of Class B common stock issued pursuant to the Founder Option Net Exercises and (vi) 1,180,329 shares of Class A common stock underlying RSUs for which the time-based vesting condition would be satisfied within 60 days of December 31, 2018 and assuming the satisfaction of the performance-based vesting condition. Subsequent to December 31, 2018, a portion of the shares described in this footnote were transferred between the trusts described in this footnote for estate planning purposes."

People use them? They don’t have the international that Uber has but they also don’t have the baggage.
So your argument

They are not making an argument. They are trying to translate my words in hopes of bridging some communication gap.

Instead of setting up homeless activists and environmentalists as enemies, it would be more productive to find mutually acceptable solutions.

I'm an environmental studies major who gave up my car well before I became homeless, in part for environmental reasons. (In the US, this is routinely interpreted as "Obviously, you are just one of the useless and incompetent poor, not qualified to do any well paid work" rather than "Obviously, you are an extremist nutcase environmental enthusiast willing to walk the walk -- literally! -- not just talk the talk." Cuz: logic (by which I mean prejudice and classism).)

So, I don't know why on earth you think I personally am setting up homeless activists and environmentalists as enemies. I see myself as qualifying for both labels.
Yeah I think Google really screwed up when they forced YouTube into the G+ framework and started enforcing a sort of real ID with small exceptions (allowing single letter initials). I think the exceptions can after an uproar. The biggest challenge was people didn't see a reason to use it since the market was already saturated. Also they didn't provide any good tools for automating content creation which helped them avoid spam but also made it less than trivial for content creators to implement a G+ presence.
That's why I'll never accept automated systems for determining things that need a human with context. "We used our black box and it says you're guilty." - what do you do against that? There's nothing to argue and inevitably you'll end up facing some tribunal where a group of people are going to decide your ultimate guilt. What if they use their own black box?
> In Turkish, for instance, the dotted and dotless letter I are two different letters, unlike languages where dotless uppercase I corresponds to dotted lowercase i.

In this case, I'd argue that Unicode should provide codepoints for Turkish-specific versions of these letters (or at the very least a separate codepoint for a capitalized version of a dotless 'i', such that it can always be assumed that the Latin uppercase I is meant to be dotted and can be displayed as such when using a Turkish locale). Alternately, the Turkish alphabet should have its own Unicode codepoints entirely, thus circumventing this issue (just like how Latin A != Cyrillic А != Greek Α).

> the Linux kernel source tree itself has include/uapi/linux/netfilter/xt_rateest.h and include/uapi/linux/netfilter/xt_RATEEST.h with different contents.

That's a rather horrific code smell, and I'm surprised Linus didn't chew someone out on the LKML over it. If they have different contents, then they should have meaningfully-different names (in this case, maybe xt_rateest_target.h v. xt_rateest_match.h?). It looks like there might be other files there with the same issue, and they should be fixed, too (as should any other files that reference those headers).

Like, just because it's possible to stick the barrel of a loaded 12-gauge in your mouth doesn't mean it's a good idea to do so.
Yup, they're real basterd. I'd give them a middle finger every time I see one, but it's not the driver/nurses who deserves the blame.

Two people. Working for less than 10 years each. Spending billions of dollars of other people’s money.

Speaking as a Founder myself.... Honestly their stake is too damn high. They didn’t do 0.001% of the work required to build the company. Could you make the case they even had some unique skill or insight that meant they were providing even 1% of the business value? They were just first.

And they weren’t even the first with the idea of how to build a “Lyft”. They were just the first on this particular cap table.

Twitter. Has been a (large) net loss since IPO, just finally started turning a profit.

Ultimately, depends on what you mean by success. I don't know of any companies that were VC cash burners, IPO'd, and then delivered great results over the next 5 years. I'd say that some must exist, surely, just don't know which they are.
How can someone with a right mind actually think you can quantify and calculate one’s work and say equal pay for equal work?

But these guys wouldnt be broadcasting this to everyone - just the people who were idiotic enough to look at the spoofed data. They are conducting acts (albeit crazy ones) in a private setting. Technically, thats really what they are doing, and it would be hard to prove otherwise.
That depends on how close you're looking at the tail. Things like ISP servers that purposefully or not corrupt information, caches that cache things for weeks after the ttl expired, ISP servers that simply don't respond in a timely fashion.
