Traditionally brick and mortar retailers, for whatever reason, don't seem to use pilots and rollouts.

At least not to the extent expected.

The closest explanation I can think of is that so much of store operations' focus is on standardization (which itself is a tough problem), that deliberately disturbing standardization seems anathema.

That said, it's definitely changing in some chains. But you'll still get tons of blank looks or red tape in most, if you want to run an experiment like that.

> MOOS [0] is focussed on autonomous marine vehicles

Core MOOS is just an efficient low-overhead IPC middleware, exactly like core ROS but, in my experience, smaller and faster and easier to use. You can use it for literally any communication between multiple distributed processes, robotic or otherwise. I think ROS became more successful at first because of better branding and promotion by Willow Garage. Now it's all network effects.

MIT's Ocean AI lab, by virtue of being an Ocean AI lab, uses MOOS for marine vehicles, but other groups have used it for other things as well.

The old faithful Eratosthenes. The 2300 year old experiment used to refute no curvature being detected using modern optics in the year 2020.

That experiment is irrelevant because it assumes the metrics of the Heliocentric model. Meaning, it assumes the Sun to be much larger and further away. The Geocentric model proposes the Sun is vastly smaller and more localized. In that scenario the same phenomena would occur.

This is correct - P/Invoke is not required because all interop datatypes can be expressed in BeefLang, whereas C# does not allow certain types of datatypes in structs (IE: pointers to structs, statically sized arrays).

They said they'll keep looking to see if they can find anything. I'm curious to know where the author of the book got this information.

Sorry buddy, but it looks like the timing isn't great for an app like this. If anything, you'd probably want to sell to enterprise instead.

I think that's exactly his point, actually, although I thought that was quite well understood. E.g. "How Asia works" explained the difference between taiwan/japan/s korea on one hand, and philipines/indonesia/malaysia on the other hand exactly around this axis.

Tyler Cowen tends to be one of the few famous economist who do admit that even though not well understood, there is such a thing as "culture" that influences economics and that is important, so I guess that's his angle. Another mystery under that angle is why France managed to modernize so well in XIXth, even though it had bad institutions. See e.g. Rodrik/Cowen talking about this in https://medium.com/conversations-with-tyler/a-conversation-w... (search for "Barrington Moore" section). In How Asia Works, the author argued quite convincingly about the importance of land reform, and how splitting huge landlors domains into small pots of lands was critical. As each farmer would get incentivized to improve their production, skills and market mechanisms develop much more quickly.

VC: The Rules of the Game
It's a problem all over in many big cities. Toronto is experiencing the same issues. Small businesses are being pushed out. You have a Deli or a Coffee shop that has been there for decades close and some kind of Boutique shop move in since they can afford the 5-10k a month in rent.

The trend now is for small shopping plazas or outdoor malls being sold off to developers to build Condo complexes. Complete neighborhoods have no shopping anymore forcing residents to drive instead of walk to get groceries or enjoy a stroll.

It doesn't help that these cash strapped cities (Toronto) just rubber stamp any new development since the tax haul will be several times what they got for what was there. A 20 story Condo brings in a lot more revenue then a parking lot and strip mall. I won't even start about all the green space they are selling off to developers. It's out of control.

About scid[0], I looked at it when I started, but it seemed to be largely inactive by that time, it didn't do what I needed, and the documentation wasn't really good enough. I was also turned off by the excessively generic nature of everything - there were just too many templates. At least that's what I recall.

> which has been built hand-in-hand with its IDE environment

This is a red flag for me. What this implies is that the design of the language is likely heavily based on the expectatio that it will be used with the given IDE.

Basing a language on C and C# in 2020 seems like a very uninformed choice to me. Sure, C is a great language, and C# is very successful, so they must be good right? But I suspect that line of thinking is also what made the languages as successful as they ultimately became.

In a world where even javascript treats 0 as false, because it's what C did, whenever I see a programming language doing things "the C way", I just assume it's cargo cult language design, because most often that's what it is. That's not to say that there can't be good reasons for doing things the way C did them; after all, C did most of them for a good reason.

As for the C# part; other than it also falling into the cargo cult language category that copies C without understanding C, I don't really like it's idea of object orientation (which is really just javas idea of OO with a fresh coat of paint). What syntax it copied from C is acceptable, but tell me a modern language that doesn't have somewhat acceptable syntax. Even functional languages don't look like lisp anymore (except lisp itself, of course, which makes up for its inconvenient syntax with other advantages).

I mean they pay roughly 3-4 times as much for the same level of service as the single payer healthcare in my country. So it's a massive market with much larger profit margins, the lack of vertical integration adds not just one, but many layers of profit generation (and total cost increase) compared to a single-payer solution, and you can skew the perverse incentives in favor of your product in ways that are not legal or possible in other countries (e.g. lobbying/bribing doctors to favor your new drug). So yes, it's definitely influential, and it attracts companies, but not only in favorable or sensible ways if you're a consumer/patient.
It is not so much about the tool helping a future dev re-invent the solution in a high-code platform. It is more about preventing lock-in. I'd like to see a vendor whose business model embraces the fact that their most successful apps will move to something more powerful. Where they consider themselves to be a stepladder up to a fully developed app, and not a platform that will take over all of enterprise IT. So they would be more of an internal app incubator, not a permanent app hosting platform, focusing on service to their customers, and therefore when it comes time to move on they are a fully engaged partner, not an adversary.

At the same time, it would be terrific to help the devs on low-code platforms avoid mistakes. Flag redundant data, point out when they have written sub-optimal workflows, give them easy ways to implement re-usable code blocks when the system notices they just wrote the same function twice with one parameter change. Data imports are also always a struggle, because most anyone can figure out how to get a CSV or Excel file brought into a system, but reading from a web-based endpoint, or parsing data from Word files tends to be beyond the capacity of most users, even if the system itself supports it.
I'm a retired programmer and now Uber driver in Silicon Valley so I often talk shop with my riders. I was giving a guy a ride to make a pitch for his product to a Japanese company. He related that his biggest challenge so far was when Walmart licensed his product and they insisted it absolutely could not be hosted on AWS so he had to transfer over to Azure. Obviously Amazon and Walmart are competitors and that might apply in many other situations.
Oh my. This does appear to be a path towards Marxism. You also missed the call for 10-page "solutions" to municipal and regional government problems.
When devs give a link to their twitter account, their chat, etc. they certainly wouldn't mind reading a kind personal comment from time to time.
There is improvement, but it's gone from somewhat unusable to just abysmal, at least in my environment. YMMV, of course.
DEC sold its StrongARM (ARM-based) business to Intel in 1997, before DEC was taken over by Compaq in 1998. It resulted in Intel's XScale business, which it later sold to Marvell.

Compaq abandoned DEC's Alpha for the HP/Intel Itanic, so Intel didn't get an Alpha business. However, Compaq sold the Alpha IP to Intel in 2001, before the HP takeover in 2002.

I'd be interested to know what happened to the Alpha architects, Richard L. Sites and Richard T. Witek. A quick search doesn't find anything interesting.

I remember there was a breakaway of DEC engineers founding a small chip design company, but can't remember what it was called.

> This seems just as with any other search warrant - it's a specific search sanctioned by the court; just as a physical warrant for your house will involve LEO's that can search your underwear drawers for to verify if there's something relevant for the case, the same applies for your online records.

No, not really. A physical warrant might be issued for your home, your work and maybe one other place you frequent.

However, because this is very much not a specific search, but rather the whole year of data, it's more akin to issuing search warrants against every business you've walked passed in a year, whether or not you actually entered the premises, and that's just to begin with.

And if you tried to issue warrants in that matter, they wouldn't approved, because you do have certain reasonable expectations of privacy with regards to a court-approved search. Specifically, that a court will not explore things that are not pertinent to the case.
Show HN: Saker.build – A modern, incremental and distributed build system

This is a smart solution - it's great that stories like this are getting attention. I'd like to share a similar project that I'm working on called Terrament. https://www.terramenthq.com/

Terrament is building underground pumped hydro energy storage (UPHS). Just like other pumped storage solutions, UPHS is extremely cost competitive (measured by LCOE, levelized cost of energy). It's extremely efficient (80-90% round trip). But unlike most pumped hydro, you can build UPHS anywhere. Just like this liquid air solution, you only need a couple acres of land. Many people assume this would use lots of water, but it doesn't because it's a closed-loop system.

I see that Heindl energy's solution was also mentioned above -- I love that design. Though, our analysis suggests that our design will give us better capacity.

Thanks everyone for your interest in this important field! This is not just a booming business, it's also critical for supporting the sustained growth renewable energy.
Hey HN! Over the past few years, I've developed saker.build and decided to open-source it. It supports all features that a modern build system should, it's language idependent, performs fast incremental and clean builds, allows distributed compilation, and supports build cache (WIP).

It was designed to be extensible, you can create your own build tasks or even replace and mix different scripting languages for your build. There's an Eclipse plug-in with support for writing build scripts (content assist, inline documentation, outline).

It may still have some rough edges, but I'm curious what you think!

Hm- maybe your experiences are different, but for projects I've worked on, the game state is way too complicated to be usefully inspected and manipulated with a REPL. Especially if you are doing any sort of data-oriented design such as SoA or ECS.

There are quite a lot of other complicated factors such as "what thread does this run on?" and "when?". When you are debugging and hit a breakpoint then you basically have a REPL in the Immediate window...

The problem with this is that black-hat SEO's have learned to mimic "independent blogs" and their linking/referencing networks (blogrolls, etc.) to the point that search engines are basically forced to discount all of these results. We need trusted, curated guides to the "independent" Internet, like the ODP/DMOZ of old. For both humans and search engines alike.
BitBanged SPI in Go, an Explanation

Why does it seem no one worries about what we might break in humanity by disrupting the evolved pattern of death. It's a network characteristic selected for in living system, and very few creatures have survived into our epoch without developing the capacity to die.

It's literally an evolved feature of our lifecycle and our existence within this web, and it terrifies me (esp everything going wrong already in our world) that we're not being more critical and cautionary toward life-extension....

Every time I read about life extension, I have almost zero positive thoughts about its effect on our common good, and it's just "oh shit, this is going to have bad outcomes for us all" :/ It's pursuit feels like peak selfishness in our individualistic society, one that really need collectivist thinking.

I believe (but would love someone to prove) that it has to do with the way real estate is financed.

The value of the property for loan collateral is based on rental rates and assessors understand vacancies happen. Therefore it makes more sense to have some vacancy to trade up for a higher rental rate.

Given how leveraged commercial real estate companies are it wouldn’t surprise me to learn that they optimize around this rather than true cash flow.

I don't think they're usually a scam. Typically, small startup (which may have quickly grown into a larger one) with idealistic founders who fancy themselves as being forward thinking and pro work/life balance and think that an unlimited PTO policy will allow employees to take care of themselves. Likely they at some point worked somewhere with a very strict policy and saw bad things happen to people who had medical problems, family emergencies, etc. and don't want to subject their employees to that. The reality of course being that nothing is truly "unlimited" and instead there's an unspoken limit that you don't want to cross (because it will affect your performance reviews whether it's mentioned or not) and the fear of accidentally doing so means that people take less time than they otherwise might. Then of course, because people look at how much time their coworkers take off to figure out what the "norm" is and stay on the safe side of that, the "norm" edges even further down over time and eventually no one ever takes time off unless it's a true emergency. So generally, I think their heart is in the right place; they just didn't fully think through the systemic effects. Or who knows, maybe by now some truly unscrupulous execs have figured it out and are actually doing it on purpose...
Rust on windows has targets for msvc or gnu. The MSVC integrates better with Visual Studio and other Microsoft libraries for development. One downside I've found is that it dynamically links against a msvcrt DLL. Which means you may need to download and install a Visual C++ Redistributable package to run.

The gnu target seems to be fully static and run everywhere with no dependencies.

Occasionally that better execution is overlooked because it looks like just a bunch of features, but a confluence of features often changes the game.

A rope and pulley attached to a vertically-moving platform existed for a really long time, and then someone bolted on a ratchet, and it became an elevator, which (with some iteration, and marketing) gave birth to skyscrapers. Another one is LXC, which existed for 5 years before Docker's confluence of features (and impressive marketing) made it ubiquitous and changed the [backend] tech landscape.
