Yeah, Boeing gets (and rightfully deserves) a lot of flak these days but updating the 20-year-old 777 is very different from updating the 50-year-old 737.

More specifically, the 737 design had so little ground clearance that the bigger, more efficient engines used in the Max had to be mounted in a different position than before. This change resulted in different maneuvering characteristics that Boeing tried to patch with crappy software. The 777, on the other hand, is a much bigger plane with plenty of clearance and the new engines are only marginally larger than the old ones. I don't see Boeing messing with the engine positioning needlessly here, especially in the wake of the 737 Max fiasco.

>I’m not sure what you mean by saying Julia is more expressive than Cython, given that Cython is as expressive as C.

I mean expressive in the sense of how much you can get done per unit code/time. Perhaps a better way of phrasing it: for most problems X that I encounter in my work, I can write code in Julia to solve X faster than I could write C/C++ to solve x, and also faster than I could write Cython to solve x. Excellent type inference is a big part of this, along with macros, multiple dispatch, and libraries designed with performance in mind (e.g. https://juliacollections.github.io/DataStructures.jl/latest/...).

>In this shop’s particular situation, it’s mostly the switching costs to Julia that cause it to lose the debate. The firm has lots of systems software, data fetchers, offline analytics jobs, research code, etc. With Python & Cython, they easily write all of it in one ecosystem, build shared libraries that span all these use cases, rely on shared testing frameworks, integration pipelines, packaging, virtual envs, etc.

>I always like to remind people that in any professional setting, ~95% of the software you write is for reporting and testing, and 5% at best is for the actual application. Out of that 5%, another 95% never has serious resource bottlenecks and taking care to write super careful optimized code for the 5% of the 5% can be done in nearly any language. Choose your ecosystem based on what best solves your problems in that other 99.75% of cases.

That makes sense then. In my firm at least (and in my team at least) the case is different: we're mostly full stack, so each member will be responsible for the whole pipeline from research->model_development->backtesting->production_algo_development->algo_testing/initial_trading. In this case 95% of my time is spent writing research code, running research, and writing production code, so if I can double the speed at which my research code runs or double the speed at which I can write it, that translates into a massive increase in my productivity/output.

No, as long as you prepare whisky in the traditional way, as in aging in barrels, aging is not marketing. Older whiskys tend to be smoother and have more complexity in their taste. While there are good younger ones, 12 years is the default for a good whisky with 15-20 years adding quite a bit quality to that on average.

There are alternative ways to create a whisky, I recently had quite an interesting burbon, where the barrels would be subjected to pressure cycles quickly - seems a huge factor in aging is the seasonal changes to the barrel, with the pressure cycles they emulated seasons in a fraction of the time. They got the equivalent of a 12 year old burbon in a couple of months.

Also, quite a few large distilleries started whisky editions without a stated age on the label. There they use a mix of barrels, old and young to achieve the taste. But, they either don't state an age or the age of the youngest barrel involved.

In any case, stating the wrong age on the label, is plain fraud.
This is awesome, especially the Zeus one!

And AWS' initial strategy is to move its internal services to Graviton2-based infrastructure. Graviton2 required significant investment, but AWS can garner returns and improve its operating margins due to the ability to cut out middlemen involved with procuring processors, power savings due to Arm and efficiency gains from optimizing its own infrastructure.

AWS services like Amazon Elastic Load Balancing, Amazon ElastiCache, and Amazon Elastic Map Reduce have tested the AWS Graviton2 instances and plan to move them into production in 2020.

Normally I try to find Primary sources rather than secondary like Zdnet [1]. But I think those exact wording was quite widely reported at the time.

They say they are not Anti-Intel or AMD. Which is true. ( They are only Anti x86. ) And they say the same to UPS and Fedex at the time.

Python has operator-overloading, so you could imagine encoding some dimensionality into types such that `class Percent` has `__eq__` that knows about `class Probability` and similarly carry forward division or multiplication into runtime type info. I don't know of any libraries that do this with much success.

Personally I would view such a thing as a cool demo (or a wild abuse of operators) but I could easily imagine it becoming infuriatingly difficult to analyze/debug if operations started returning outlandish units (`print(x/y) => 1 gallon/light-year`).

My favorite tool for doing informal dimensional analysis is the `units` command-line utility. It is surprisingly adept. (It's a part of BSD and built into mac)

I understand that in those cases rqlite/dqlite is used. But that it just a technical detail. My point is that I am running two servers: one with the app and Xqlite and another one with Xqlite.

In case of a neo-serveless setup, I also have two servers: one with the app, the other one with the db server.

So what are the benefits of the Xqlite setup? I looked into that before and for one thing, Xqlite is slower (obviously) then just sqlite. So speed is not a key benefit. I also will have to manage both servers myself.

At least for a seperate db server I have the benefit that I can buy that as a service, incl management, backups and such.

What’s the point? An attacker would still be able to set up their malicious AP with the same encryption key and be able to tamper with traffic as if there wasn’t any encryption to begin with. In this case the encryption adds friction and degrades user experience while not improving security in any way.

CaO is created by frying CaCO3, typically heated with coal. You can then mix it with water to get cement. At least that's what I learned in school.

How would you like to create CaO without providing energy if the reverse reaction is exothermic?

Or am I missing the fact that there's a lot of unbound CaO in rocks?

Also, production of cement is one of the major sources of CO2 emissions.

The Trapper Keeper came out after I graduated high school. But we had 3-ring binders before that - they were fabric covered (like a cheap denim) and had metal rings which made a loud snap when you closed them. They had good & bad aspects - you could draw on the fabric and customize your binder (something the Trapper Keeper couldn't do until they allowed an artwork insert years later). And bad: the metal rings would get bent and not meet up anymore so your papers would fall out.

So far as customization - the thing we'd do with textbooks is cover them in paper grocery bag material so you'd have something to draw on, as well as protect the book so you wouldn't be charged when you returned it.
That is interesting explanation, any references about inelasticity ?

@robenkleene I concur with your pov and re conspiracy to clear things up - the way you see things is more a result of the law of unintended consequences than anything else - right?

One of those (partially at least) is IMHO the way swift makes apps unextendible when you compare it with the flexibility of objc app in this area and that's a huge part of creative search too.
Ha, well, we all started somewhere. My first website also use PHP, although I never did the spaghetti, not even as beginner programmer, but then again I learned it differently in school and also did not make use of JavaScript on that website ... Ah but actually that's not true, my first website was HTML, CSS, JS on a file hoster and uploading in the correct sequence to update the links in the files.

> We can't force people to start with Rust. :|

Yep, we cannot and should not force. Perhaps Rust is also quite difficult for beginners to use, even if with that comes great learning. I consider it a fine language. I only wish it had proper tail call optimization. If it had that, I would probably start a project in it tomorrow. sigh.

Good luck to your friend, hopefully they will dip their toes into something beyond PHP soon.
When I first met arduino (and quickly more embedded boards afterwards), the hard part was not C[++], nor a toolchain around it – I’m a C guy since ‘00. It was the fact that this area has few de-facto standards on how things should cooperate. Basic tutorials have no notion of event loops, you just for-loop forever and poll pins. But once I’ve got few non-standard devices, like that pressure sensor I got somewhere in the city, it all falls apart, because e.g. the time required to talk to it via provided library consumes enough cycles for your entire process to be late on physics. And vice versa, your logging is not async and interferes with signal timeouts. You simply spend tens-thousands of cycles spin-locking on i/o and there is no way to fix that without rewriting “drivers” under some “os”. Idk if haskelling everything could help with that.

I decided to just move on to high-mhz stm’s or even -pi variants, where a whole different stratum of software lives (seemingly), but luckily project folded for unrelated reasons. My conclusion was that if you’re a software developer, don’t just go embedded, it is not what you used to and routes you can take are limited.

Edit: obviously missing some details here, and it was 7 years ago, would like if someone would elaborate on the state of the embedded world today.

The issue is not the name, it is the comprehensiveness of the training required. The MAX had iPad training only, and MCAS wasnt even in the manual, let alone the differences course.

Besides, the 777 wasn't designed for low loading at small airports.
Oh, I haven't even thought to check. Sorry.
I think you missed the point.

Units != dimensions.

E.g. angle in radians, degrees and full rotations differs by a factor. It is a typical, and common, mistake that would benefit from such system.

Tiny Seed Fund: Accelerator for BootStrappers, "... we do this all without the headache of traditional fundraising, loss of control, or the pressure to build a unicorn."

So, it provides some clarity as to why BaseCamp (formerly 37 Signals) aided in the production of the report, certainly when you take their own genesis and growth into account. As far as I know they only had one small outside investment, from Jeff Bezos:

People are missing the fact that the oil and gas industry is strongly in favour of CCS for 2 main reasons:

1. It makes extracting and burning oil not so bad - no need to make rules limiting oil extraction, we can simply start some CCS projects.

2. Injecting CO2 into deep oil wells actually helps get more oil out of them. Get the government to pay for CCS, while the oil company profits off increased yields.

I’m hardly a heavy/regular library user but between picking up discount passes, picking up a video now and then, donating books, using a library to work in when I’m in a city, and even doing research, I’m in a library a good dozen times a year. For most people, that actually would be frequent movie theater going by count.

ADDED: And furthermore, as other comments have observed, most of library visits are dropping in for maybe 5 minutes. If I were only to count the times I spend multiple hours in the library, it would probably be a couple times a year--and that's mostly because a few city libraries are often convenient places to hangout with free WiFi when I have some time between appointments/activities.

Well, I meant https://en.wikipedia.org/wiki/Evolutionary_pressure

Think of a population as holding at any given time a number of individuals carrying mutations. The fringe mutations, such as being able to be hosted by a different type of mosquito (say, better survivability in the host) don't provide much of a benefit to survival. But if the default host population goes away, those mutations become super valuable and will be selected.

Reason language development is happening at https://github.com/facebook/reason/

Like huy-nguyen said, this is a tooling & ecosystem effort on top of OCaml ecosystem, and the language syntax is a small part of the effort. It's a bit scattered, but apart from ReasonReact, there is also https://reason-native.com/ and Esy that are parts of this bigger picture.

Both OCaml and Reason communities are also quite active in producing tooling and libraries, I'd suggest following the relevant forums. I believe Reason's development momentum is not centralized around a core Reason repo/org and a team.
Due to the increased difficulty of attaining certain milestones, there has been the gradual increase and acceptance of more than one funding event occurring at Seed; ie Seed 2, Bridge, Post Seed. All before an actual Series A event.

Not disputing that VC's (and others) should do more to highlight the difficulty, the slim chances, the demanding road both professionally and personally, that maximised exit valuation need not mean profit-making, nor revenue-generating, need not even mean sustainable if not propped up, nor some other things which would make my response off-topic.

Agreed. I find comic book movies boring, so that removes a lot of options. I did go to the movies for the first time in ~3+ years to see 1917. Great movie. But, even with a movie I liked, the theater tried to ruin the experience by showing ~30 minutes of ads/preview prior to the movie.
I second "Mom Test Book" (you can watch author's YouTube talks that cover the topic https://blog.kowalczyk.info/article/06817da6d15d429db3eec8f2...).

The thing is that most people think that idea validation is "Hey, this is my idea, what do you think?"

"Mom Test Book" describes a way to discover valid ideas by asking question, not asking question to validate ideas you had by yourself.

Still not easy by this point of view changed the way I think about it forever.

And now I can't help and see how everyone is doing it wrong i.e. instead of discovering ideas people would be willing to pay for, they have ideas and then look for validation (if that).

If someone had asked me about the number of times I have gone to the library, I would actually have a hard time being able to answer that well.

First of all I don’t have a great memory of specific things in my day to day life. Ask me today what I had for dinner two days ago I could venture a guess based on what I usually have for dinner, but I couldn’t give you an answer with great confidence.

Anyway, part of what makes it kind of hard to define how much I have been to the library is also because I sometimes pass through the library at the university.

And I have borrowed like one book recently, but I don’t remember if that was within the last year or not.

But actually what I was wanting to say was that, different people might count what constitutes a visit to the library differently. To me, simply passing by to drop off a book does not constitute a visit. Whereas going there to borrow a book counts. And going there to attend some sort of event counts. And going there to browse the shelves for a while counts. And going there to just sit down and work with some of my own stuff on my computer counts.

Technology dramatically changes in 20 years. Would you be happy to drive around in a 20 year old car design? I for sure would feel a little uneasy about the rather basic airbags, and the lack of proper FEA modelling of the crumple zone.

Same applies for planes.

That's a misleading comment, and I can't find a valid point in there. You can run C on a different platform than UNIX, or "run it on bare metal", just as well. If you write C, you make reasonable abstractions, to achieve some amount of OS independency, just as well. And typical usage of "rich language runtimes" is on one of the mainstream OSes, just as well. You even often have some OS specific code in there, because the OS is not entirely interchangeable.

So, the OS does not lose more of its meaning if you move to rich language runtime environments. Those language environments are mostly about garbage collection. Most other things that make the OS "lose its meaning" are just libraries (that you can write in any language).
