Disagree on this completely; I've studied this space before and using something like Spree and Saleor seems like a world of trouble unless you are willing to commit significant, permanent, and highly specialized development resources to it.

Also, the ecosystems for many of the solutions you describe are quite fragmented and niche; I looked into Spree / Solidus / Saleor devs in my country and couldn't find one, whereas I could find thousands for other more popular (PHP-based) solutions. In my case this would mean that if you wanted to hire local Python / Rails devs, you would have to train every single one of them in the use of the framework.

Finally, I don't think these solutions are as fully featured as some of their competitors. In my comparison I saw that Spree had a plugin for bundled products but the code repo looked desolate, full of issues and left to rot for years, whereas many others had much better support baked in.

Due to all of the above, many medium-sized companies with typical use cases are going to be better served by a more out-of-the-box solution, rather than taking charge of a Rails or Python codebase that's going to grow wild with custom code.

As for Shopify, it's definitely not for mom and pops anymore - they are serving massive customers throught their Plus offering, and their move to an open and comprehensive API (with both REST and GraphQL) allows anyone to build highly customized headless apps around it.
Now that! Is much more constructive information. I'll look for those methods sooner in the future.

This is basically my exact argument that you attacked me for just a few comments above!
Insofar as trump repeats the same tropes, he's being quite leftwing. Protectionism and mercantilism are typically leftwing positions as they are contrary to free markets.

> before it began investing on building one.

That is my point. Americans chose not to do that. A loss of manufacturing didnt "happen to america" like some crime. American society chose to be educated differently, chose to spend and raise taxes differently, and presently, continues to choose to do so.

The "blame china and outsourcing" narrative is just misdirected scape-goating. Trump's repetition of it is a pretty strong signal of its mumbo-jumbo narcissim.

China has invested in its infrastructure to an incomparable degree. The US has not, does not, and will not. It is your fault.
It would have challenges if it worked with people nearly,as then it can go south pretty quickly. However,the demo was some digging im mines,which isn't too bad if there are no peopl around.
Nice trolling!
Would not be surprised; they found a forgery factory somewhere in the boondocks a while ago that also forged collectibles like posters (https://news.ycombinator.com/item?id=23784998).

Of course, if it's about the contents then a forgery would be impossible to make.
No, licenses are not standards that require code changes to be adopted. The OSS community has a long history of moving off old licenses to new versions and the OSI lists many retired licenses due to this. (When Apache replaced their 1.1 license with the current 2.0 license, there was no complaint about proliferation. Rather, the community adopted the new license and today 1.1 is entirely dead.)
Fault rates of 50% will make a lot of people angry, but if you're in the "right" 50% you won't notice it.

The Airpods are possibly the single best-selling Apple SKU at the moment, so even a 10% fault rate will generate a lot of unhappy people.

But are you referring to interactions on twitter or reading other people's post? I don't have a twitter account and couldn't care less about comments on youtube videos or twitter. But I do follow certain people (just by having them as favorites in by browser). I read twitter as kind of blog.

You can still refer to the absence of filters, you read people's opinion without the filter of a newspaper editor. But I never thought newspaper editors should be trusted for anything.
I often complain how people are ignoring context nowadays. Twitter makes the problem worse, because of the nature of it, there is not even space for the context. Just a knee-jerk-raction propagation machine.
There's research that they use dynamic soaring more, getting energy from the different wind speeds at sea level and a bit above https://www.youtube.com/watch?v=uMX2wCJga8g
The birds are better built for it though. The keel in soaring birds is massive and not comparable to our weak chests.

It's not even that annoying for them apparently - birds can sleep (kind of) while soaring as well.
Hardly counts a valid reason now, does it?
> forcing an entire generation (or two) work

Err... no. 996 is a recent culture of work in Chinese IT.

The reason subsitance-living agricultural workers moved to cities and factories is the same reason they have always done so in history: farming is dangerous, risky toil.

A wage is highly stabilising, and highly attractive. You do not need to "force" people from farms into factories.

> Why would a profit-driven corporation spend money to bring the supply chain back to the US when there is no economic reason to do so?

The US can engage in the same state-funded programme of infrastructure investment, skills subsidy, and massive sector-targeted tax cuts. That it chooses not to is the explanation of why the US isn't competing successfully. NOT "996".

Its just scape-goating to blame "the despicable Chinese!" when at the same time you're doing nothing to compete with them.
don't forget that the wings create lift, i.e., the body hangs between the wings, it's not the body that holds up the wings, it's the other way around.
Albatrosses apparently have some kind of a locking mechanism just for that. I would expect it in other soaring birds too.

Decelphalized monoclonal humans.

Turn off neural tube development genes so they never develop brains. Grow them in test tubes, then hook them up to life support.

They can never be conscious beings, so you can do anything with them. They're essentially large-scale tissue cultures.

You can harvest them for blood and organs, create knockout lines for different studies, and speed drug development and verification tenfold. Population studies on everything imaginable becomes tractable.

We have to get out of the biological stone age and develop real automation primitives. We don't have a real test kit. Decephalized monoclonal humans is the reverse salient we need.

I hope someone does this. If nobody does it and I wind up becoming a billionaire, I'll do it. It needs to be done.

The multi-machine case is probably where you'd feel the benefit the most -- managing which container runs where, network, storage pooling, etc, that is what lxd is for. LXD sits on top of lxc to get things done, so you can imagine it like just a scripting layer to access lxc.

If you're well served by ssh/scripts/ansible to set up the machines and managing them by manipulating lxc on each one then there's absolutely no need to change! But what lxd offers is a dynamic system that manages that (and other things) for you on the fly.

Stolen from their features page:

> Secure by design (unprivileged containers, resource restrictions and much more)
> Scalable (from containers on your laptop to thousand of compute nodes)
> Intuitive (simple, clear API and crisp command line experience)
> Image based (with a wide variety of Linux distributions published daily)
> Support for Cross-host container and image transfer (including live migration with CRIU)
> Advanced resource control (cpu, memory, network I/O, block I/O, disk usage and kernel resources)
> Device passthrough (USB, GPU, unix character and block devices, NICs, disks and paths)
> Network management (bridge creation and configuration, cross-host tunnels, ...)
> Storage management (support for multiple storage backends, storage pools and storage volumes)

If you don't need nay of these things, then no biggie, but if you're trying to orchestrate those containers on multiple machines it might be worth looking into a management solution. The cross-host container/image transfer and live migration are pretty cool but not very necessary if you can just... let it die and restart somewhere else.
Until 4chan comes and makes a challenge about who can remotely burn down a house faster. I think you need someone being personally responsible that the robot does not destroy stuff and people will not do this for free.
Interesting that they went for expensive microcontroller based servos, I guess they consider Realtek chip RC cars to be just toys.
> I assume this is hyperbole, but for anyone who is unfamiliar with either system this statement isn't right

And for people who don't know what they are talking about general reactivity "isn't right" ... not sure why anybody cares about the opinion of those without the requisite understanding.

In actual functionality, and applications, LXD does not offer the same functionality as K8S, nor does it claim or attempt to do so. The "similarity" you are pointing out is between K8S container runtimes[1] and LXD - and even they are quite different, and there are already many container runtimes.

Same here. The battery is obviously not what it was (I get about 90mins of phone calls before I have to start the 1-in-ear-1-charging dance), but apart from that, and despite my typically abusive treatment (fell on tarmac and tiles multiple times), they still work great.

Well, there are studies suggesting standard surgical masks are at least partly effective against viruses. In one study, they were showed to be equally efficacious against influenza as FFP3, probably due to incorrect donning and doffing. See this review.

Where in these places has normality been resumed? When can we go back to seeing smiles?

Have you considered the long term social cost of reducing interaction between people? Or is that the plan?

There is no end goal here. Just a bunch of short term reactions that are based upon fear and propaganda not hard data. Why so much social change for a virus where the median age of death is over 80, and the majority of the population under 40 are not impacted at all.

There have been an estimated 31.5 million deaths this year so far on Worldometer. 1.5% of those were Covid. How many of that 1.5% would have made the end of the year? It's time to get some perspective and control those amygdalas.
That's only for first-world countries with Apple stores. Without both of these, you are out of luck.
A conventional arm? Oh no thank you. Heavier, need a motor out on the elbow joint with another expensive low-backlash gearbox, mast has to be heavier to support the off-axis torque loads, grasp trajectories have another DOF or two. Skip that, please. And it's not like conventional arms are even cheap! If you could buy a decent 1.5 kilo payload arm for less than $5k, you'd have a whole different argument.

From the way the telescoping arm moves, I'd bet dollars to doughnuts it's driven by a flex-tape linear actuator. Pretty cheap, lets you put the heavy motor right next to the mast, no precision bearings, backlash not so much a problem.

The whole package really is a great design, I'm a big fan. You can tell Edsinger has been using robots out in the real world, with regular people beating them up.

You still separate your views from your controllers and sql injection is not an issue when you bind params, but even if you are using an ORM you can't change and add columns without some impact on the code (you need to update forms to add the new value to the created objects, show it, and, presumably, do something useful with it).

And that also assumes that you are using databases as an object store. Databases are also useful to answer questions like: show me the number of users who have signed up each day for the last month.
It is something terrible, and really scary. My best friend at the time suffered one at 23 years old. He eventually recovered but he suffered a huge loss of concentration capabilities and had to drop from college eventually. He also fought with speech impairment for many years but with a lot of training he was able to recover 99% of it.

By that logic, Microsoft Windows is open-source, because I can view its source under the MS Reference Source License.

This is the key distinction between "Source Available" and "Open Source". Open Source is open. That means I can modify the source and redistribute my changes. If I can't do that, the software is closed source, no matter how much marketing you apply to it.
Crazy! I have had the same issue and have had my left airpod replaced twice.
I HIGHLY doubt Google has any interest in hiring someone with a Google career certificate. Instead they will keep sieving the top performers of top universities.

It's all for publicity, improving their image, making those career certificate holders more likely pick Google products (for the companies they will work for)...
Thoughts about naming variables and methods
Unfortunately, it's Apple themselves who effectively expanded the meaning of -gate when they refused to acknowledge the antenna issue in an iPhone version (5, iirc). They were trying a coverup ("you're holding it wrong!"). Antennagate transitioned -gate into "large-scale hardware manufacturing problem that company won't admit", and here we are.

Thanks! That's good to know because I've been having troubles with Ubuntu 20 and have been considering switching back to redhat.

Then the only remaining part would be figuring out how to do zfs on root in redhat. I do it with a chroot bash script for Ubuntu server atm, but hopefully there's a debootstrap kind of thing on redhat that I can use as a base.
Already now this looks like a very useful tool for a person who is bound to a wheelchair. It can easily reach things at different heights, including floor level, which is hard from a wheelchair. Its base is smaller than a wheelchair, so it can get into narrower spaces. Such person probably has an open, level, and uncluttered floor plan already, which works well for the robot. Accessories, such as the vacuum cleaner, can be installed by the operator (after the robot fetches them). Autonomy is great when it works, but even slow teleoperation is better than having to have a helper around 24/7.
>> How is it that we are all paying $280 and still have to replace them every year.

That was always the deal; the non-serviceable li-on cells degrade significantly after a year of constant use.
Exactly! I used to be in the latter camp as a child - allowance paid for some stuff, but not a lot, now I'm in the former group and am happy to subsidize the enjoyment of those less privileged than me. Especially because some of those people are probably going to be inspired and create some great art I'll really enjoy.
That's not a fair comparison at all.

The gymnast example is fighting against gravity with absolutely no external factor other than personal strength, but the warm air / wind resistance pushing against the wings that allows the condor to fly for so long without flapping is contributing immensely to their ability to hold the wings in place.
Well, that's pretty well known. There are different tiers of mask. This article looks at the evidence for them:

https://www.cidrap.umn.edu/news-perspective/2020/04/commenta...

Some kinds of masks can stop much finer grained objects than droplets, e.g. gas masks, but the kinds of masks people are actually wearing are just regular cloth masks and there's no evidence they accomplish anything and plenty of evidence they don't: the article goes into this.

It's logical: your glasses fog up exactly because the hot air is exiting the mask and travelling outwards, that's why it's hitting the cold glass of your glasses.

But it's not sufficient to merely deflect a small amount of air from each breath in a different direction. That's not permanently trapping infected air; obviously it can't be because otherwise CO2 saturated air would build up inside your mask and suffocate you. The air has to be able to circulate. The mask is meant to let air through whilst blocking ... well, whilst blocking what? Virus particles? They're far too small. Water droplets that contain virus? Maybe, but only if you're actually spreading water droplets around and if you're asymptomatic then clearly you're not. Yet everyone is being forced to wear masks even if they're visibly healthy, on the basis that "you might be infected without realising it". The science behind this is garbled nonsense, being pushed on people because something must be done, this is something, therefore it must be done.

Stopping stuff travelling out is a different matter.
If I was 10 and had a robot and my friend also had one, we would be setting tbem to fighting each other, or doing stunts, or doing silly things.
You're right about this expanded list of things it can't do. However, the conclusion is a bit on the negative side. The Roomba or any of the autonomous grass mowing robots can't do any of the things you mention either, and yet they are commercially successful in the consumer world. The article mentions that this robot is still a research platform, so as you say, it is not currently ready for consumers. However, there is a lot of potential here despite of the limitations.

What features of LXD enable fault tolerance and high availability?

What is the basis for this claim? K8S and Docker also runs everything in user namespaces by default, so why is LXD more secure?

Are you sure a set of robot arms, trained over many generations to minimize motion/water/energy use, while also minimizing dirty dishes, would necessarily use more water/energy than a dishwasher?

I'm deeply sorry for the loss of Grant having lost an engineer friend the same way.

An engineer friend of mine passed away due to brain aneurysm few years ago. Higor was in his twenties and had just achieved moving to Dublin after managing to acquire an Italian citizenship through his Italian ancestors being from Brazil.

I fantasize I will build a machine to extract his consciouness before the brian aneurysm saving him (but also causing the brain aneurysm).

Being an atheist I guess that's my way to hope for a way to see him again.
I miss you Higor

This was not really true back when browsers allowed sharing caches between domains because of different versions and fragmentation of CDNs, and is definitely not true now when a.com and b.com would not share a cache for skypack to avoid fingerprinting.
This is a terrible comparison, bird physiology is nothing like human.

This is not relevant, but this strikes me as a big cultural difference between wherever you're from and where I'm from. Here, the first thought to complete that sentence would be "he strikes me as someone you'd be friends with". I wonder why "hang out at work" was the first thing that came to mind for you. Here we don't tend to think in terms of "people we hang out with after work", we generally have "friends we first met at work" and "coworkers with no other social relationship".

I know it's a small thing, but that's where cultural differences usually manifest, and I find them very interesting.
You can. Use Feedly or any of the analogues. Much more sites support it than you think. You don't need twitter... well, for basically anything.
