If you have the financial and engineering resources to deliver a quarter of a million of anything, then the Raspberry Pi is completely irrelevant. Broadcom (or one of their rivals) will very happily work with you to develop your product.

The whole point of Raspberry Pi is to provide a convenient SBC for people who don't have those engineering resources. If you're somewhere in the middle, there's the Compute Module.

Ugh.
A Pi for UniFi, a Pi as a print server (older model) for a USB laser printer, a Pi as a print and input server for a thermal receipt printer that only has serial (or a 350$ option for a 10Mbit ethernet addon) + a button to fetch a hotspot code from UniFi and print it for a guest for limited guest access. And a free floating Pi for various functions, sometimes as an I2C board, SPI interface, Scan server, placeholder when one of the others is in maintenance etc.
Plenty of such block of flats have AC these days. Lots of people installed ACs in the last several years, since the extreme summer heats became the norm.
The cheaper espresso machines have reliability problems, so people spend more to get a better product. The ability to modify and repair the machines is helpful also.

> Or, second guess, as the engine is colder, it emits less NOx, because NOx appear when the combustion temperature is too high.

That's a major issue. NOx emissions are caused by engine heat interacting with nitrogen and oxygen from outside air, which gets you to a nasty trade-off. Run the engine hotter and get more efficient combustion, therefore less CO2 emissions; or run the engine cooler and get less NOx emissions. By design, Diesel engines combustion happens at much higher pressure and temperature than gasoline engines, which is why diesels produce much more NOx.

Diesel emission fluid can reduce NOx, but also reduces efficiency, meaning more CO2 will be released.
Zig is a great project that I am very happy to support with $50/month on Patreon. Andrew consistently communicates progress and gives periodic updates on Twitch/YouTube.

I don't have any relationship with Andrew other than I want his programming language to exist and replace C. I saw it on another HN post just like this.

I would encourage you to watch the talk linked from his Patreon page.

When you add up adapters and cables the rpi is closing in on a chromebook on sale. So not that cheap any more.
Seconding this... it'll just barely run on the Zero W, but you need 64-bit Java to remotely access your controller through unifi.ubnt.com, and there'll be long delays whenever the database needs any maintenance.

(I set up a Zero with the Unifi Controller -- connecting to the LAN using a Chromecast Ethernet Adaptor -- about a year ago, and had this problem, so I switched to a 3B, and all is well now.)
You're welcome. I have had to wind a couple of companies down that weren't successful and both times we did everything possible to help the employees and even the couple of contractors we had. I learned this ironically at GE when I worked there early in my career. We had layoffs of staff, both professionals and non-professionals and the level of effort and resources GE had us put into helping those people left a huge impression on me.

One thing I have seen in the startup community over the last 20+ years is generally people do their best to help the employees. Although there are some pretty infamous examples of the opposite, those seem to be the minority.

Also in terms of references, caymanjim is right when it comes to enterprises, but small businesses and startups I find are usually a little more reference friendly to a degree. Personally when hiring people though, I generally skip any reference checks for the exact reason he listed, as they are a waste of time. However, for a critical position I do generally call around to people I know and see if I can learn anything that might affect my decision, but for the average position I wouldn't bother.

Well, if we're going that route, it also has no buildings to speak of, and even if it did, opening windows would likely be disastrous!
A great option I've found is to use the DietPi distribution that has Pi-hole configuration/install wizard built in (https://dietpi.com)

After having various weird network issues and instability on a different OS with Pi-hole (updates often broke), I switched to DietPi, and now my PiHole and OS upgrades are extremely stable.

The DietPi installer/configuration for Pi-hole sets up all the networking for you in the install "wizard", took all the weird networking headaches out for me

Indeed! I'm not sure why I don't already have three hard drives from friends, it's 10x cheaper than S3 or Backblaze B2 or any such thing. I've had this idea for years, but seeing that someone else built exactly this[1] while also having time for it soon gave the idea another push.

This is absurdly reductionist and rhetorically dishonest.

Let's try absurd reductionism on some other things, to demonstrate why it is bad and not cool to use it:

Aside: Shout out to the telemarketer who pressured me to get a land line years ago because they're the only guaranteed access to emergency numbers and "never go down."
Here's food for thought: while a proper firewall and network segmentation is a well-established best practice, I'm not sure this is a winning battle.

There are probably a few dozen organizations out there that are properly implementing strong information security practices, and my hats go off to them. But they are the few, and I have never worked for one.

Despite best laid plans and policies, every place I have worked has always had some improperly secured services somewhere on their network. And every place that I've worked has had segmented networks that people end up relying on. And the people working for these organizations are often aware of the improperly secured resources, but they're only in the DMZ, and there are many other things to worry about, so it lives on.

Especially now that we live in an IPv6 world, why not just run everything publicly. Push security all the way down to the applications themselves, and rely on the software development lifecycle process to catch security issues.

Every service has to be secure. And they can get an awful lot of help in this from things like a service mesh architecture, where you're getting mutual TLS from something like Envoy, and the applications won't accept a network connection unless they're specifically authorized.

We need to stop relying on firewalls and network segmentation entirely, and just run everything on the public Internet, and make sure every service is secured.

I will say, when a zero day comes out in whatever proxy you're using to secure your services, you are in for a world of hurt. But there are zero days in firewalls too.

There's a certain asymmetry here. If you're under 25, that'll eventually fix itself, but once you're over 40, you're going to be over 40 for the rest of your life. Given that, it doesn't really make sense to treat these two cases exactly the same.

It seems incredibly risky for the bottom line and unwise to make such politically risky moves against half the US people. The action seem to assume that the reigning silicon valley ideologies are 1) right and 2) will win.

By assuming corporate and regional dominance will last through violating some peoples trust in favor of placating others desire for power, it is just a matter of time before you open up a weakness that someone elsewhere can exploit. Or as they said in Detroit: "People will still need cars". To which you can answer "Yes, but that doesn't matter if you loose your competitive edge"

I'm interested in working on a lifestyle business rather than chasing a unicorn. I have the classic spreadsheet of ideas tucked away, but I'm certainly open to others ideas.

Strong preference for B2B. No experience in blockchain or ai.

In my previous attempt at putting together a business, I felt pain from a lack experience talking to customers so I spent a few years in a customer facing role as a senior success and support engineer for a fairly well known startup. I now love working with sales & marketing, grinding customer development for ideas, but still keep my coding chops sharp.

I just got started with postgres and have hated the procedure syntax so much that I've begged my manager to go to MSSQL or upgrade to the latest database version (I'm currently on 9.3). And fortunately, the database is small enough where this really isn't a big deal.
But my guess would be to search on the web for one and try them out.

That's a fair criticism, thanks.

That said, I don't think "taken with a grain of salt" takes it nearly far enough. Project Veritas is not an unreliable news source. It is a propaganda agency led by criminals. I don't know of a single completely true news story ever produced by them.

Beginning an argument with the antecedent "If Project Veritas is telling the truth about this" brings us into the realm of fun and fancy. If someone said "If unicorns are real and produce large quantities of greenhouse gases, then man man may not be responsible for climate change," it'd be a reasonable logical statement, but it's still not useful in a serious discussion about anything.
On the one hand, I appreciate the level of innovation and forward thinking that Google is doing here. It's a lot of neat ideas and designs.

But on the other hand, I don't like the idea of a private company deciding how a city should develop- especially not my city. No matter what they say, they are a for-profit publicity-traded company whose goal, always, is ROI for investors. And that conflicts with the goals of city management, where the goal is the benefit of the public and not just those with money.
How come all Google related news end up on the front page, not this one though?
Mate this is rediculous!
In the process of moving our Hardware Test infrastructure(Think Selenium for testing hardware)over from Windows SBC based solutions to a R-Pi-Zero based solutions. Applications range from driving stepper motors, sensors and generating pass/fail results. The inital investment is in porting all the code written for Windows to embedded linux but the investment pays off in the long run in cost minimized by moving away from a Windows desktop. Will do a write up of how i achieved it once i have some concrete results.

Just searched a bit more for MPI integration with various languages. I find things like this kind of heartbreaking:

https://godoc.org/github.com/cpmech/gosl/mpi

It provides MPI bindings in Go, but they really should have provided an MPI layer internally so that the Go metaphors of things like channels and goroutines "just work" with no special syntax.

I think this is where I'm getting stuck. So much cluster software provides interfaces to send/receive data and get the current thread's CPU id and total number of CPUs. But I'm not finding much info on doing this directly in the kernel or language runtime so that the client can be written in a topology-agnostic fashion.

Edit: there doesn't seem to be a Go-native MPI runtime (yet) https://groups.google.com/forum/#!topic/golang-nuts/t7Vjpfu0...
I have an E61-based machine that feels like it's at the end of its life. I think the cam and push-rods are so worn down that the valves aren't opening fully anymore.

It effects both (and that ticket is about both if go through the comments).
There are design patterns that are beneficial regardless of temperatures - high thermal mass (smooth out the extremes), reversible blinds (black/white) - control extra solar power coming into your home.

Besides, Europe is not such a small place either. Many houses in the South are geared towards hotter weather and have the the features you described.

They also get notoriously cold in case there's a cold snap, since they aren't insulated very well.
Why would it be less reliable in theory? The obvious argument against is that it's 'expensive' [relative to what you need], not, I wouldn't have thought, that it's unreliable.
> Mes is inspired by The Maxwell Equations of Software: LISP-1.5 – John McCarthy page 13, GNU Guix's source/binary packaging transparency and Jeremiah Orians's stage0 ~500 byte self-hosting hex assembler.

stage0 is one of mes' inspirations, so I'd say there's a level of connection there.

Apparently mes is also working towards being able to be compiled by M2-Planet by the same author [0], at which point it might be possible to eventually build mes from stage0 as it can now bootstrap M2-Planet.

What Is a Strong Correlation?
The software has already been produced. Games are a kind of art and "outdated systems" are needed to play them. Nobody would say that we shouldn't produce the instruments needed to play classical music since there has been plenty of time to do so in the past and when somebody wants to listen to it they should use digital recordings instead.
Yes, I see it like a crossover between Geogebra and Inkscape.
You have a very valid point. Systems like this should work flawlessly and should only be activated when it is really necessary otherwise by the time we need them they'll be switched off by people that get tired of being woken up.

Case in point: smoke alarms that wake up half the neighborhood when their batteries need replacement.
For someone who supposedly values clarity, I have no idea what point you’re trying to make.

To make my own point as clearly as possible: I am certain that people who say Muslims aren’t good Americans are racists and are a disproof of their own statement if they say that racism doesn’t exist in America.

If you have some counterargument to that then please go right ahead.

> Women were naturally granted the right to vote in 1776 without any strife or suffering.

Depends on the state, if I'm remembering correctly. New Jersey allowed certain women and african americans to vote until (I believe) 1806.

Dirtying history to make our advancements larger is also dangerous.
Unfortunately I did not find that episode of Black Mirror interesting.
Yes, definitely. Even with the improvements in the latest version, it still comes up way short of what you get from Windows/MacOS.

The thing is, by definition, the registry is a monopoly for a certain TLD. So the idea was that those registries need to be regulated. What if they would just ask insane prices?

A registry has an 'easy' part, and that is actually maintaining a list of names and associated data, and providing that as DNS zones.

The hard part is dealing with individual customers. Providing service, collecting money, etc.

So the idea at the time was to have lots of registrars competing on what service they provide for what price and having more or less regulated registries that provide a fixed service at an agreed price.

By and large this system worked.

Early on, it was not clear if large zones like .com would actually scale. So there was some restraint of registering silly names, because that could lead to problems.

At some point, computers got fast enough and big enough memories that large zones were no longer a serious worry and everybody moved in to get all the nice domains.
If I'm not mis-remembering, there's an interesting section in Dawkins' The Selfish Gene about cooperative grooming behavior (I think it was in some sort of water fowl) and how the birds deal with cheating behavior (individuals that accept grooming without reciprocating). My takeaway was roughly:

Any exchange of value based on trust is exploitable. The simplest cure is excluding the exploiter, but this doesn't scale well. The exploiter can skate on anonymity if the community is large enough to continually prey on someone new. Spreading news of an exploiter's behavior to others can greatly improve how well this scales, but this behavior also requires trust.

I think the more direct problem is with scale, and that the internet is at the nexus of many trust issues only because it has ramped up the scale and scope of many interactions.

I'm not super optimistic on solving this intrinsic problem of trust in social exchanges, but I do see this framing as a silver lining. It seems at least plausible to iterate offline at significantly smaller scales on mechanisms for building and maintaining trust--and rectifying its breaches--in ways that do actually scale.

> But the last two are not KPNs fault.

Agreed, but 112 not being reachable definitely is. KPN made a big stink about it at the time how other 'crappy' providers could not be trusted to deliver a thing of such national importance and so they got to do it exclusively rather than to have multiple redundant systems by different providers. I'm sure there will be some second guessing of that decision now.

Agreed that sounding the national alarm over this would be an overreaction, as is the fact that they used the national alert, lots of people are going to disable it as a result of this and that will make the system that much less valuable.
