> Cities: Skylines is an outstanding successor, but it lacks much of the charm of the SimCity series and feels more like a sandbox than a simulation.

I feel the opposite.

I think SimCity's charm is just nostalgia. C:S is definitely more of a simulation, as it simulates individual vehicles, including commercial traffic. All the SimCity games before SC4 used a statistical model for traffic, and SC4's path finding was very unlikely to use highways and mass transit without a mod.

And with mods, you can make C:S look like a photo [0], or add outlights to make it look like Borderlands [1].

I hope the irony of this topic being discussed on a (mostly) software-related forum isn’t lost on anyone.
Luxottica ran the CostCo Optical centers for a little bit. I believe they got out of it because they were not making any money on it.
Meant to say, they're still making an extremely good profit off of it.
How do you know?

Do you seriously think that nobody has attempted to coordinate a major terrorist action since 2001?
Hi zzzcpan - Yes. The global edge fabric internally uses CRDT operations. It is a conscious choice to not expose the CRDT data types. The idea being the developer work with APIs & Query layer as they do with other databases and underneath the system take care of translating to necessary CRDT operations. Convergent counter is in the works and will be available shortly.

The system has strong consistency within a region (aka datacenter) and strong eventual consistency across data centers. Answering your question, yes we do converge (merge) the changes across regions using conflict-free operations.

Intent prioritization rules comes into picture only when it is impossible for the system to determine the intent of the developer when two conflicting changes occur across regions.

I hope the above helps.

It's not city building but Factorio (factory building). Be VERY careful as it's an extremely addicting game. It pushes ALL the right buttons for me and I highly recommend it. The mod community really takes a great game and makes it amazing (but play at least some Vanilla before you go modding like I did).
Um, that simile does not make any sense - because we're not talking about their website, but their blog about Jepsen tests, which showed some shortcomings (and it is not derogatory, it's extremely rare that somebody passes Jepsen with flying colours).
> While there is no single accepted theory for why collapses

This kind of reasoning rests on the success of disciplines like physics and chemistry where scientists have found general laws upon which they can build solid models of reality (within some extreme limits). History doesn't lend itself well to this kind of thinking IMO, and only serves to cloak the innermost nature of history: it's uniqueness. Instead we should realize the unique characteristics of our culture vs all preceding (and similarities too, by all means). It is a much more difficult exercise, but also much more rewarding since it can lead to a much better understanding of our predicament.

One thing that comes to mind is our complete interconnection and dependency on a few points of failure like no previous civilization. Our demise might not take several decades like the Roman empire, it might be over in a few days if we don't change course(s) and build better resiliency.

20 people is too big for a single scrum team: break it up into two (at least) smaller teams.

Do not use it as a status update ("what I did yesterday" and mostly "what I'm doing today" are noise), but do use it as a means to raise visibility on blockers, for members working closely on the same tasks or features to schedule follow-up meetings (sometimes known as "break out" meetings), to update the team on a shift in priorities for deliverables, and possibly to prioritize newly created bug tickets (though often this is more appropriate out of the standup).

FWIW As someone that touches debian package building once in a blue moon, it seems like there's wide variability into which is the "right way" to do the actual build step and that everyone has their own artisanal preference. pbuilder, debuild, debootstrap, dpkg-buildpackage, sbuild, fakeroot all leave me scratching my head.
> the only brands you should buy for performance are Maui-Jim (great lens / polarization) or Oakley (impact safety)

Sunglass Hut doesn't sell them, but Serengeti makes some great lenses. Maui Jim might even not make lenses that are both photochromic and polarized, but Serengeti does.
But there is sufficient competition - you can buy no-name glasses for a few dollars.

You can’t buy these specific luxury fashion brands of glasses cheaply but that just means you don’t think the name is worth it. It’s not a ‘rip off’.

I agree that Linux' design sucks, but I don't agree in the operating system taking the role of distributed computing.

Distributed computing is really hard because all applications are efficient with different computing/storage models. You can look at Redis, BigTable, PostgreSQL, TensorFlow, MapReduce just as an example. There's no reason why you couldn't do deep learning on top of any of them (they are all generic enough to execute the algorithms), but you can easily have a 100000x speed in execution speed, in which case being compatible doesn't have any advantage.
Thanks, glad you liked it!

1) Honestly, there are a _lot_ more than just three startups here who seem to be growing actively. In general, I tend to bias towards great product quality and design, which puts Vitally, Split, ClearBrain, and Kustomer far up my list (and also a part of the reason we've highlighted them). That said, there are a ton of other companies in the space doing really interesting things.

2) No, at the heart of it, our revenue comes from our happy customers. We don't plan to sell or share our user’s data with other companies the way data brokers do. We just help our customers make better use of their own data for their own businesses. Occasionally, we’ll create trend reports like this that show aggregate trends to help our customers make better decisions.
Most of them. Pretty much all the major OEMs have announced plans for fully electric lines within the next 5 years and have already started developing test vehicles and tooling for EVs. Outside of Tesla, the frontrunners currently are probably Audi (they have an entire e-Tron line that just isn't pushed much in the US), BMW (same with the i line), Nissan, and Chevy.

Keep in mind, too, that cheaper batteries doesn't just mean cheaper Teslas, it also means cheaper hybrids which are likely to remain popular for quite some time.
This is addressed in section 8, "Institutions part 2: political incentives":

> the political system favors NIMBYs and really anyone who complains. Infrastructure construction takes a long time and the politician who gets credit for it is rarely the one who started it, whereas complaints happen early. This can lead to many of the above-named problems, especially overbuilding, such as tunneling where elevated segments would be fine or letting agency turf battles and irrelevant demands dictate project scope.
Can I just have all of my mail emailed to me? That'd be great.
I've used the beta for a year, it's pretty good but there's a few bugs. And it adds anxiety because now I'm aware of letters that didn't arrive then show up later. Before i wouldn't have thought about it. I save the email until i get it.
yes, that's probably about right (based on my remembrance leading product for cost estimators widely used in appraisal & assessment). construction costs tended to beat inflation by a bit, enough to compound to 50%-ish over 60-70 years.
Measurements presented in a paper are not a good indicator for whether an idea is practical. If the results weren't good, the paper wouldn't exist.
Yes, this is known as a rebuilder.

There is still work to be done, but NYU was one of the organizations working on developing and running a rebuilder. The idea is that you pull buildinfo files from https://buildinfo.debian.net/, then try to verify them and if you got the same artifact you sign that you successfully verified this binary package.

A user could then configure "I trust rebuilder X, Y, Z and I require that at least N have successfully verified the package" before installing it.
Announcing Dojo 5.0.0
Hi nagarjun. My company (https://tonic.ai) builds dev tools and we've noticed recently that companies with remote teams have been using our product for an unexpected use case. We are trying to investigate it further. Would you be willing to chat with me? If so, I'll drop you a way to get in touch and we can chat.

quick fyi, it does not compete with OP's product.
As a web designer, I can tell you this whole post is the worst kind of garbage content marketing. They call their product web design 3.0, and yet they say Webflow, a product superior in almost every way, doesn't qualify for that designation, please!. In addition, their homepage for their own product is pretty terrible design wise and I have a strong feeling this must have been upvoted with bots.
Haskell is still a pretty awesome language tho, so using it on the frontend is pretty sweet. Nothing about the language is problematic here (with the possible exception of laziness which is one reason why I personally prefer purescript). And Miso is actually pretty awesome and easy to use. The main issue is with tooling, especially the slow compiler. My hope is that a wasm backend will be developed soon, hopefully along with subsequent speed improvements. Compiling a ton of non-DOM library code to obscure JavaScript makes no sense. Not to discredit the work of the ghcjs team, which created something pretty awesome and useful, but most of that would make a lot more sense in wasm. Beyond that, it needs bells and whistles like webpack integration and source maps. But really, despite its warts, it is quite usable for frontend and shouldn’t be discounted.
Ah sorry about that, this is a great point.

I generated these via the seaborn palette in matplotlib[1], but agree that these could be way clearer. I'll see what I can do about changing the line type on them to make them a little bit more differentiated.

Long piece. The crux of it:

Force them to listen to unsettling stories of violence and predation. Isolate them, and make them bicker with each other until they speak as one. Then grant them the power to lock a man in a cage.

This is the closest the piece comes to addressing nullification. I wish the writer had spent a little more time on that. For someone who's regretted a decision for 20 years, I'm sure he's spent a lot of time thinking about doing what's right vs following the law.

This is a very good question, and to a substantial degree, this is what we did. We have internal QA systems that overlap Jepsen that catch most issues. We also ran our own Jepsen tests on the core product properties last year, fixed some issues and identified others, and reported the results on our blog.

However, correctness testing is fundamentally adversarial, like security penetration testing. Building a database is not easy, and testing a database is not easy either. It is a separate skill set, as anomalies that lingered for decades in other databases reveal. The engagement with the Jepsen team is explicitly designed to explore the entire product surface area for faults, not to apply Jepsen as it currently stands. Thus, a lot of custom work ensued on both sides to make sure that the database was both properly testable, and properly tested. The result of that work is what you see in the report.

The typical Jepsen report implicates not just implementation bugs, but the entire architecture of the system itself. Jepsen usually identifies anomalies that cannot be prevented even with a perfect implementation, which didn't happen here.

Some vendors restrict their engagement with the Jepsen team to only what they have tested themselves already, although those tests are not always valid. This was not our mindset—we wanted to improve our database by taking advantage of Kyle’s expertise, not present a superficially perfect report that failed to actually exercise the potential faults of the system.

I suppose you have a point. I have believed (known?) for a while that this was simply not true so since the magnitude of this difference is what most would call not statistically significant, I treated it as worthless. Though, I imagine those who were still of the mindset that men were still paid much more would find this much more interesting.

Odd that TFA mentions the blood clot but not the amputation, and then claims the twins are in good health besides the ovary issues.

Regarding point 9 about the inability to look outside North America. I always wondered why it seems transit agencies haven't looked to bring in teams of people who have managed/built successful projects in Europe, Asia, or even closer like Mexico City.

California HSR for example went to solicit bids from foreign operators and selected Deutsche Bahn/German Railways. But AFAIK the initial design work/RFP/proposals were done by California and domestic engineers, who obviously wouldn't have much, if any, experience in designing or managing HSR construction.

Would an experienced team be able to overcome a very different regulatory and political environment to make a difference in cost and time?
This is also why at least one actually-independent board member is a good sign: at least someone involved has a fiduciary duty to the common stock holders.

I just want a plug-in plug-in hybrid kit for regular ICE cars.

Plug it into a port in your trunk and it takes over all electrical loads (roughly 10-15% of engine load, more when driving slowly), until empty.

Maybe it can also pre-A/C the car (are AC compressors electric yet? Other pumps are (coolant, power steering, brake assist and obviously fuel).
Dockup is like Jenkins X, but easy to setup for people who do not know Kubernetes or helm charts. Also we have features like single-use pre-seeded DBs and a deployment form for deploying a custom combination of branches, for example, development branches from two different repositories.
I'd be curious to see the numbers on this.

I thought 99% of the wealth belonged to 1% of the population or something crazy. Are you sure taxing the middle class would bring in more than taxing the ultra richer?
I've heard the $100/KWh number regularly, but I think it only applies to certain products. For a large sedan, that is still $10k of the manufacturing cost. For smaller cars (Model 3 sized), 5-6K. That is still going to be a substantial price hike, IMO.
That makes sense. Costco sells a lot more than just eyeglasses, so it's a rare case where Luxottica just doesn't have leverage. If it's not Luxottica, it's someone else, but Costco's brand is very strong, so there's no concern about quality where you'd otherwise judge based on price/brand.
> It doesn't even seem like anyone has interest in building $200,000 houses anymore

From a bit of online searching, I imagine it's between 0.75 and 1.25 man hours per square foot of house to build in labor costs (that number may differ depending on size of team/expertise, I imagine).[1][2] Depending on average pay rate for building involved, which varies widely based on area and cost of living, you might be looking at $50k to $100k in labor costs. That's before land cost, materials, permitting, power/sewer hookups, etc.

> but they will sell you a poorly made condo for $400,000 and $600/mo HOA fees.

In some places the lot cost is $200k, or more. It's hard to build a $200k house when your margin is negative before you've started building.

And in places where the lot cost is more like $100k, do you want to build a $300k house with low margin, or do you want to build a $400k-$600k house or condo with much higher margin? The problem perpetuates itself, as high density and high housing costs lead to high land cost, which leads to maximizing profit for area strategies that say to build higher end houses.

One of the solutions to this is to be willing to live in higher density housing, such as a condo. This lets building still target high margin while providing somewhat cheaper housing. Or build up, into more multi-story complexes. But people want homes with yards, which is why this is a discussion about how nobody can find a $200k house (you can, just not in the more populated areas), and not a discussion about "how to achieve housing cheaply".

It find it hilarious how many people who ought to know better claim that GANs do not rely on memorization of source data. Obviously they do. At some point people even studied how connectivist memory could work (e.g. Hopfield networks, which I've just started looking into - fascinating stuff). Somehow that branch of research is never mentioned in any of the recent deep learning papers.
Code commenting is an activity that's hard to get just right; it seems there's either not enough, or none at all or even worse - too much!

I've found the following works really well: when doing something non-obvious then comment it immediately. Otherwise wait to see what arises from the Amigo Review. If the reviewer asks any questions, answer them with comments. Once the reviewer stops asking questions then the code is sufficiently commented.

If you were given stock you'd be taxed on the whole value immediately, because you are getting something of value whether or not it's liquid. Getting compensation tax-free at time of receipt, as options do, is already a pretty great tax deal.
I have to agree as well.

Our team has switched from a burndown chart to a "Confidence Check" at each standup. On the count of 3, we each hold up fingers rating the chance to complete the sprint out of 5. It's been a good way to see if the blockers are likely to be overcome and see if anything was missed etc. Our combined gut feel is a lot better than the burndown chart for reporting and for starting conversations.
Well, $100/kWh is a very rough estimate. A ballpark number. Depending on what kind of niche you're talking about, it could be anything from $50 to $200/kWh. An electric car can in principle be cheaper today if you only need a very small battery.

$62/kWh would pretty much mean that BEVs are cheaper to operate in nearly all segments though.
I can't share the exact number, but it's high (above 33%) across all customers on our paid plans.

For companies on our business tier, it's even higher (above 66%). Most of these companies are doing more advanced data analysis, and it's hard to replace the utility of a warehouse for analysts at a certain point.

The marginal utility of income is not measurable, whereas the percentage of income that gets paid as tax is. That's why "regressive" and "progressive" taxation is defined in terms of the measurable thing, not the unmeasurable thing. What you're saying is simply that a progressive tax system is better because it attempts to take into account the marginal utility of income.

And then everyone starts arguing about how progressive the system should be to do that properly. :-)
Gaming, especially with the blow-out of BR games, has become idolized by the masses. And the culture around them is changing for the worse.
