Due east from where? San Jose?

Having just driven that way last week over Hwy 130 - it is rugged mountainous terrain that would be quite expensive to develop with rail. Pretty though, and worth the drive in the spring for those who live in the south bay if you have a reason to take the long way out to the valley.
It seems like Facebook does a thing that doesn't scale, in the interest of time: feed a minimally processed video until other streams are available. That makes sense, but I wonder if it also means that video quality on Facebook generally suffers when high-profile events are taking place.

Context on that wonder: I've always noticed that news outlets seem to carry downright horrible quality user-generated video clips of rallies, protests, and the like. Where everybody's carrying around stellar-quality video gear in their pockets these days, I've never figured out why that is.
Never heard of this is any US state or country I’ve worked in and that’s many.

Yes, but at a higher level and less formally than UML.

A sequence diagram doesn't need to be ordered in a time sequence like UML, it can be good enough to just articulate and number the flow of information on a normal solution diagram.

A class diagram assumes we're using an OO language - we need to define schemas for data, but not classes. The engineering team knows how to structure their code, as an architect all we need to worry about are the boundaries.
No, I would say most languages and IDEs are not as complex/bloated/unpredictable as Apple developer tools.
I just switched IDEs/operating systems, so I'm using Anki to help me learn that Cmd + Shift + Z is revert changelist and so on. When I'm waiting for something to compile, I tap Anki and let it reinforce my memories that were about to expire.
Patterns are commonly (but not only) symptoms of some failure of features on the language but at the same time they are just vocabulary.

Patterns exist in functional programming as well, any map/reduce operation is a pattern, any monad is a pattern. It's a proven way to achieve a goal, it's easy to compartmentalise under a moniker and refer to the whole repeatable chunk with a name.

Unfortunately a lot of people only learn how to properly apply design patterns after doing it wrong and/or overdoing it (mea culpa here!). It's easy to spot the bad smells after you've been burnt 2-3 times.
As a recovering platform engineer, nearly 2 years out of the game, i identify a lot here. My experience is that platform engineers are mostly people who never actually write code for the platform that they have built, other than toy services to test, which are usually written in a language which isn't the company default.

Communication is difficult because platform, like SWEs, are supporting people, but the support is direct, so platform often have a torrent of people asking for things. This is a problem when the SWE doesn't know what they want because they are a newbie out of university, or worse, they know what they want, but don't know how to work the insane platform mono repo that requires 9 items on a checklist to get a IAM permission added that the platform team member told them about in a support slack channel.

I think a lot of platform teams also make their own lives harder by making too many abstractions. If it is impossible for an SWE to add a new resource to the cloud without a platform engineer helping, then platform are always going to be disadvantaged.

Control is also a big issue.

Platform want all the control and believe giving control away is going to cause a disaster. In reality, SWEs want 5% control, just to do the thing they have to ask you as a platform engineer to do anyway. But maybe platform engineers like that hero complex.
No it isn’t common. Certainly not in USA, Europe or Middle East.
The ethics board were asleep on the job. Grovelling is probably less painful than falling on your sword.
Sorry, I misread your comment. I thought you wrote that only "small languages", or Lua, can be compiled to WASM.
This is a mathematical model, not a study of empirical data. It's worth distinguishing, because models are only as good as their assumptions.

The model presumes a "filtration constant" for masks, which only apply for pressure-sealed masks, like properly-fitted N95s. Simple face coverings don't do much to protect you against aerosols, for the same reason that they don't do much to mitigate the effects of attempting to breathe in a smoke-filled room - the airflow is just redirected through the sides and top of the mask, rather than being filtered. So, while the results may have some value for N95s, I seriously question their value for "masks" as they are currently colloquially understood.
We're actively evaluating this, particular b/c: Open, dynamic acl+rbc = modern google-docs-style policies for regular webapps, postgres adapters = no change in operations (vs keycloak, orly, ..). That's been a fairly unique combo. However, we're still doing our own eval because we saw concerning issues in the gh around perf+correctness, and it's not obvious how to use it.

Curious on other experiences / alternatives. Ex: We're trying to keep the CMS parts of our stack especially boring, so django/postgres/casbin is surprisingly tight, while DB backing of a user's/org's custom ACL/RBAC sharing rules in say OPA seems more like a science project (despite looking like a great project when zoomed out), based on the docs (https://www.openpolicyagent.org/docs/latest/external-data/)

The casbin<>db integration decision was pretty wise, vs the continuing trend of policy engines bringing their own infra, and thus 'the tail wagging the dog'. I'd love to see someone figuring out RBAC/ABAC+ACLs as DB-native ~RLS, instead of having to introduce an extra moving piece of infra for every DB query, when the DB is right there!
I respect your opinion, but I disagree... I think the SpaceX and Tesla aesthetic is very stylish.

Do you think a Tesla Model X isn't a stylish vehicle?

Yay, another Rick Beato fan. Found him over the pandemic. Great music theory/engineering/producer channel.
Microsoft's Power Platform is a low code framework which works well, and generates a massive amount of revenue, as does Salesforce and some others. I recently designed and implemented a complex 500 user child protection application with PP that has been live for a year now. It was highly successful, and the time and cost taken to deliver it was far less than the cost of a hand written solution. That said, there is still quite a lot of custom code required for most enterprise level solutions even with the most mature low code platforms. Low code is not a panacea, and the same issues of how to represent requirements and design arise in the low code world as in the high code world. Low code platforms will continue to mature and improve. Maybe AI will catch them one day, but I'd be surprised if that happens anytime soon.
If anyone wants to read about mystery/crime investigation in Ancient Rome, the SPQR series is a bunch of fun fictional books (of questionable historical accuracy):

> The stories are told in first-person form by Senator Decius Caecilius Metellus the Younger (born c 90-95 BC), nephew of Metellus Pius and member of the powerful Caecilius Metellus family of the Roman Senate. The stories are told in flashback-form by the old Decius, writing during the reign of Augustus Caesar. The stories range from 70 BC (The King's Gambit) to 20 BC ("The King of Sacrifices").

For non-fiction, see Infamy: The Crimes of Ancient Rome by Jerry Toner:

> Join the historian Jerry Toner on a detective's hunt to discover the extent of Rome's crimes.
From the sexual peccadillos of Tiberius and Nero to the chances of getting burgled if you left your apartment unguarded (pretty high, especially if the walls were thin enough to knock through) he leaves no stone unturned in his quest to bring the Eternal City to book.

there is a phrase inventory tax that means unnecessary overhead but I’ve never come across an actual governmental inventory tax in any country or us state.

Yeah tell us more about reporting agencies who pretend to be independent so they can propagate information to a network of hacks, and really it’s all a big shakedown.
Who says I didn't?

When I asked what it means, there is more to it than the currently high risk, high labor, high energy input, high cost process.

All of which should be a temporary measure at most!

What does it mean?

A few things:

Major investment in recycling means major investments in nuclear, and that cycle means having to make green energy a priority and that being a lot more difficult than it needs to, and should be.

It also means continuing to produce toxic elements, containment and all that I just discussed.

What it does not mean or lead to is an acceptable end game.

All this talk avoids the fact that we end up with high concentrations of very toxic elements that can be kilo-decade time scales.

What we should do is make the investments in energy and storage we are now getting really good at, and that do not come with the crazy burdens we are just not very well equipped to deal with.

You know smoking generates a buzz, which is cool! Never mind the cancer and other impacts to follow.

You know, a big spoonful of sugar and a shot of caffeine is a big hit, so is adrenaline. Hell of a crash afterword.

We are in a place where we need to get off the fossil fuels.

No matter what we do, we are late, and there is a ramp up time.

Nuclear is a quick hit with high start costs, high risks and a very long burden that will be with us for so long we don't even have the ability to manage the problem with confidence. Hope and cope is where we are at.

Green energy is not as quick, but it will not come with all the downsides, and if we put people to work on a scale like we did for fossil fuels, we can get where we need to be, without that high burden, and in a clean, sustainable way.

High energy, healthy food takes a bit longer to ramp up, but there is no crash and overall labor output is higher, more consistent.

Generating nuclear power also generates major league problems that must be managed for an extremely long time and none of it is sustainable.

I just wrote part of why above.

Green energy is sustainable. And is improving rapidly, will continue to as well. And it comes with tech mortals can use, build, manage, etc...

TL;DR: Advancing nuclear comes at the expense of advancing green, renewable energy.

It prolongs a crutch we need to be rid of and that is highly toxic, high density energy.
> If compliance with GDPR would be a board level concern we'd be on another internet/ in another world by now.

That's the point, vast majority of people do not care about the issue GDPR tries to solve, and legislators do not understand enough to create legislation that would work, which makes their efforts useless at best, and usually harmful.

It would have been better to leave the issue alone until enough cases would have been accumulated from people trying to sue companies based on concrete cases.
This is somewhat begging the question, which is, at its core: “is the gov’t directly responsible for the humanitarian crisis at Skid Row.”
And there's been the business process engine craze in between. BPEL comes to mind which also has 'visual editors' for the business people to use.

It's too complex for them and the you pay Software engineers to use BEPL instead. Which is just a worse language to actually program in than the underlying system.

Or any other number of 'process engines' which give you a worse language to describe your actual process in and then you need to do stupidly convoluted things to do simple things. But hey, we didn't have to code!
Indeed. The problem is not with the diagrams, so much, as with the requirement for people to draw them. The code is the source of truth and the only true representation of the program.

There is value in diagrams - but that value is highest when the diagrams are derived directly from code. That is why I am making https://appland.com/docs - get the benefit of interactive code diagrams, generated automatically from executing code (not just static analysis, which is too weak to handle the dynamic behavior of modern frameworks).
As an example of internationally known brand/quality, here's a complete installed 6.6kw system from IKEA for AUD$5047 (AUD$3197 after subsidy).

Film photography is such a beautiful and romantic process, with some ingenious technical solutions to make it all work, and still hold up pretty well with the end result compared to digital photography.

It's also a huge pain in the ass compared to digital, but damn I'm going to be sad if it ever gets completely phased out.
Right? I'd also be concerned about hash collisions causing one to accidentally generate the same level twice. Seems better to use something like ChaCha; plenty fast and a much large seed space.
I'm not angry. I just find the wording misleading. I thought you did so too, given your sentence. Given the interpretation of many people in this thread (including mine), I think there is plenty evidence that it is indeed misleading. It is nice you were not one of them, given that you seem to be the only one who bought the car.

As for assuming good faith, giving all Elon Musk's actions and statements, it is hard to assume it at this point.
It's unclear to me (and apparently to the people doing this research - they state they haven't been able to figure that out yet).

It is clear, though, that not everyone gets covid, but (in Israel) essentially everyone gets the vaccine (>80% of age>16 already), so a vaccine must be significantly safer than the disease it prevents.

Furthermore, the most worrying signal they remark on is that covid myocarditis seems to increase with older age, whereas post-vaccine myocarditis seems to increase with lower age.

I've read a hypothesis that bits of free vaccine mRNA migrate in the blood, and if taken by heart muscle cells, will cause the immune system to potentially attack those heart cells when they actually express the S protein -- especially if there is some prior immunity (previous infection or cross immunity). I don't know enough to judge its likelihood myself.

Only thing I take from reading this report is that the vaccine safety is not to be taken for granted the way it has been so far with the massive deployment in Israel.
Do you think that, if you didn't know how to negotiate, you should be getting 25% less for the same work input?
Oh completely agree, there is no ‘one size-fits-all’ solution, my point is that a checklist based approach would cover most cases, and for the rest you can take a different approach.

Also just in case you are ever sick, you NEVER want to hear the words ‘oh that’s interesting’ or ‘you are an interesting case’... there are a lot of rare diseases of which there are maybe 10 cases reported in the medicine books, and sure your doc can diagnose it but there may be no good treatment options ( since there is so little data all the accepted treatments are just guesses ).

In any case, if I’M ever sick i hope i fit the checklist, at least i know the diagnosis and treatment is well known and defined.

Edited to add:
regarding hospice care, i wish this was more widely understood by non-medical people. I see so many people suffer unnecessarily because they don’t understand or their families refuse to understand. I cant speak about specific cases but I can say that some doctors have a gift of guiding their patients and some dont, and even the good one sometimes cant get through.

This is as you say a systemic problem and I dont have a good answer as to how to address it.
Most of those markets don’t carry frozen broccoli though?
It seems that that code handles just the case when target is function.

The game is Cozy Grove for anyone interested, and it's recent launch has it's subreddit buzzing with the warmth of a growing community. The game can be found on Steam.

Fun fact, the devs have submitted wallpapers that are included in the current (maybe not limited-time-only?) ~$6 LudoNarraCon Supporter Pack, but there aren't previews.

Right you are - but my point is that language designers (especially Java’s) aren’t evolving their languages to render the more tedious design-patterns obsolete - instead they seem to accept the DPs are here to stay.

Take the singleton pattern for example. It’s not perfect: it only works when constructors can be marked as private and/or when reflection can’t be used to invoke the constructor to create a runtime-legal second instance. A better long-term solution is to have the language itself natively support passing a reference to static-state, which completely eliminates the risk of a private ctor invocation - but that hasn’t happened.

OOP Design Patterns are like JavaScript polyfills: they enable things that should be part of the native platform. They’re fine to keep around for a few years when they’re new, but when you’re still using what is essentially an aftermarket add-on for 5+, 10+ or even 25+ years you need to ask if it’s the way things should be or not...

Yes... because warranties are optional guarantees of fitness being sold on top of the product. We aren't talking about a warranty on the product here, we are talking about the product itself, I have never seen a contract that says "oh, and we can steal the product back from you in exchange for monies actually received", unsurprisingly, outside of digital assets.

And of course that term is common because the default terms for damages can go beyond that (e.g. if replacement value rises).
The less nice thing, though, is that the model of the process you're starting from -- the actual spreadsheet -- has, as you say, these structural problems. And since (some speculation here, but I very much suspect that) many different processes, after having been so mangled, will end up in the same redundant, excessively-flattened structure, you can't determine from the spreadsheet alone which of these different processes it is supposed to encapsulate.

So before you can start "shifting this structure around" you'll still have to go through a standard business analysis process to find out what you are going to shift it into. And if you're already doing that... Well, then most of your promise of automation is out the window already, so what's the use of having the actual implementation done in some weird newfangled "no-code" or "low-code" tool?
The world was told by the public health apparatus, up to and including the U.S. Surgeon General, that masks were not effective. The circle was then squared by telling people to wear "face coverings" and, well, here we are.

I would have hoped that in our current age of misinformation, that sources people trusted would not actively lie, but there you go.
I don't think it's simple things, vehicle has around 60 to 100 sensors on board, some might have even more, they also have infotainment which is tablet-like level of hardware, imaging all different things they have to handle, and how reliable it have to be.
I must be really missing something obvious, since I don't know why so many replies are talking about debugging.

We're talking about the speed of production code (aren't we?) that already elides a lot of debugging features. The article doesn't say that they've found a feature for faster debugging, they're saying that explicitly marking tail calls makes their production code faster... so I'm still lost why the compiler can't find these optimizations in production builds without explicit markup.
The military or the people?
A filtration constant can apply to poorly-fitted masks, too. They just have a smaller constant.

The filtration constant for a well-sealed N95 can be 99.99%. The filtration constant for a thin cotton "face covering" can be 20%.

The point isn't that the model doesn't apply to poor masks -- it's that they have poor constants. We will do much better to include them in the model, and then mathematically predict how important it is to improve your filtration constant, than to say "those masks don't apply" and throw up our hands at quantifying the improvement that could be gained by better masks.

You raise a good point, and I don’t disagree.

This article is interesting to me because it portrays a version of medicine which treats the patient as an integrated unit.

I think a physician who can interrogate issues more deeply in addition to treating symptoms is invaluable. Maybe someone’s weight is not just a function of their lifestyle or diet, but is also due to undiagnosed, low-level hypothyroidism, for example. I don’t know that a dietician can be expected to have the knowledge and expertise to treat issues like this. Who knows, with the rise of smart medicine we might be able to replicate such a care team through technology.

Also, unfortunately, quality of treatment is in large part a function of time. And in most countries, the level of medical attention one gets is very dependent on how much they can afford. I mean, even in places like Germany that have socialized medicine, the privately insured get better care, more time with their doctors, less time to schedule an appointment, etc.

Knowing that, this might be an insoluble problem until we automate the checklist-style medicine with chatbots and ML, and then reserve doctors for the tricky cases where DDx falters.
Most people who hold bigoted beliefs permit exceptions. Feynman is on written record saying things like being surprised that a particular person was able to do physics, given that they were a woman. It would not surprise me even a little that there were some women that Feynman believed to be intellectual exceptions while also holding nasty beliefs about women in general.

Even if all of this is excused as a product of the man's time (I don't believe that all of it can be), it still adds a disappointing aura to the otherwise fascinating stories he tells.
