The idea of this book is to provide a practical guide on how to implement DDD, CQRS and Event Sourcing. I chose to use JavaScript and Node.js as alternative to Java or C#, which are often used in comparable literature. After reading it, one should understand the fundamental concepts, how to apply them and how they can work in code.

You can access a free sample of the book on the webpage in different formats.

I worked on the book for four years as a side project. In 2016, I had worked in three different projects that applied either some or all of the concepts. The last one was the main motivating factor for the book. It was a startup that was settled on DDD, CQRS and Event Sourcing, even though the developers had limited knowledge.

Together, we learned, experimented and applied as much as we could. We read "Domain-Driven Design" by Eric Evans, "Implementing Domain-Driven Design" by Vaughn Vernon and whatever we could find from Greg Young. With the knowledge we picked up and the experimentation we did, we felt in a good position. Still, there were many unanswered questions on how to put everything into code.

In 2016, before leaving the startup, I first thought about writing a book. Effectively, I wanted to create the guide the startup would have needed in the beginning. When I started, I was overly confident about my knowledge. However, throughout the years, I learned many details. Today, I know that I could not have written it in 2016 at once.

The final book is different from what I envisioned it to be at first. My initial goal was to write a short book with approximately 150 pages. The published version has now over 450 pages. However, I consider this a good thing. The book provides enough context to be read without any prior knowledge in DDD, CQRS or Event Sourcing.

I've written a blog post that covers my motivation on writing the book in even more detail: https://www.alex-lawrence.com/posts/why-i-wrote-a-book-on-dd...

I'd be happy to discuss your thoughts on and experiences with DDD, CQRS and Event Sourcing. Regardless whether it is about their combination, their sometimes counterproductive conflation or one of the concepts. Finally, if you have any input or feedback for me, it would be highly appreciated!
They should have included links to the study and to the conference that they referred to.

> Doesn't say how much of each or which ones have been found to be medically significant.

Plastic waste is probably not uniform enough to make those measurements and have them be correct for other collections of platsic waste.

> No evidence presented that the chemicals are actually making their way into our bodies in clinically significant quantities.

Its probably not wise to wait until the water supply is contaminated with medically significant amounts of endocrine disruptors to tell people there’s a problem.
53% of their revenue is from sales and trading. I'm only saying is that if Goldman Sachs had done this short there would not have been any outrage, calls for investigation and so on. Institutions routinely pull off massive profits from retail traders. As soon as one day it reverses then there is all this faux outrage. lol

The problem is covid is short-term and part of a family of well-known and well-studied virus. Some vaccine can have very long-term consequences.

There is simply no way to correctly assess the risk, unless you think that ARN therapy is a known technique. Which it clearly isn't.
I’m sorry can you explain how you are connecting bespoke mortgage backed securities and their derivatives to commodities trading?
Not just old software, but with a lot of open source software you usually have a spectrum of choice between more basic, lightweight software and more elaborate, heavyweight software. Think LXDE vs XFCE vs KDE vs Gnome as desktop environments, or nano vs Sublime vs Code/Atom vs IntelliJ as text editors, for example.

However, when it comes some software areas prone to capture, there's not only no choice, but rather a multitude of incompatible-by-design options. Due to WFH, I need to have four different bloated chat/videoconference software on all the time which all offers the same features to me. When I want to watch a live stream, I need to open YouTube or Twitch or Facebook Live which all offer the same basic functionality but no one is interested in standardizing their interface so I can just point my familiar video player to it (at least without it breaking all the time due to cat-and-mouse fights between the platform and open source developers).

I'm not generally in favour of regulation, but mandating some basic degree of interoperability so platform and software can compete separately seems like the only option.
I wonder if you could gain security while preserving agility by having build servers with exceptional (and annoying) security maintained offline. Do your CI/CD work, then chop off a weekly release and build it from source on a machine that’s been powered off in a secure room the whole time.

Still doesn’t help you if the attack is sufficiently upstream..

Just about all of that text isn't fluff, it's the point of the article, telling the stories of these particular people and giving a detailed background of the market.

I'll happily tell you that there appears to be no evidence of manipulation, so you can avoid reading an article that doesn't interest you, but I don't think it's fair to call it a buried lede.

Ah yes, my parents (who are former national editors) had told me about this sort of discontent among bureau chiefs around her, although they didn't name the particular names.
It's the latter. 2 people surrounded by cubicle walls is better than a giant room filled with desks and no partitions.

The worst I've seen so far was at Amazon. When some people wanted to get up from their desk, they had to ask their desk neighbor to stand up so they could pass through.
I thought that might of been the case as well, but based on Google Earth Pro's historic satellite data, it's been there since 2009.

Thank you so much. I was worried recounting my experience would be perceived much like the first person responded. It feels good to know there are those out there that get it.

A group of retail traders buy contracts requiring them to buy at settlement price. (TAS) They then sell contracts to get them to a flat position so they don't actually have to take physical stock.

This part is very routine. The unusual thing is that the price actually went negative so when they "bought" to cover they were actually paid nearly $40. So they profited both off the short position and again to buy to cover.
The same wat you control for anything. You assign a group to do a specific thing. If a certain group performs better, its due to the task not preconditions, because the tasks were assigned, not observed and the selection process is random.
Except for Berlin.
In the sense of your explanation it COVID-19 is indeed airborne.

+1 for Nim in that use case. The core system and std library is very flexible, so it “ports” easily. It’s been used in a few games too. I’m using it for embedded currently after a few months and while there are a few edge cases overall it’s been stable for me. With C interfaces you’ll want to add some code to make it more idiomatic, here’s my try for i2c code on esp-idf: https://github.com/elcritch/nesper/blob/e1d9f7ba13eebe45aea4...
Interesting perspective. I'm glad to hear that some of the trunk-mounted racks are good.
Yep. A friend of mine and myself got do this as well; CHM was running this pretty much every weekend as I recall. An incredible experience considering we went to the museum that day on a whim with no specific plan.

Stephen Russell was talking to the participants and Peter Samson was actually operating the PDP-1... my guess is this was a regular thing for them.

An interesting note... not only was Stephen Russell a creator of effectively the first computer video game... he wrote the first Lisp interpreter based on John McCarthy's paper.
My experience in New York and Los Angeles is that the natives are perfectly pleasant, so long as you’re aware of the local mores.

The worst people are the people who move to cities and try and fit in by adopting some caricature of these customs, which is often accompanied by engaging in hideous games of one-upsmanship with their fellow new arrivals.
Unsecured Azure blob exposed 500k highly confidential docs from UK firm's CR
That is the most requested feature and something I'm working on. It's a fun (and hard) design/data problem. Which of the 5k-150k papers do you show in the graph? And then how do you render them in a way that is both visually appealing but also conveys the most import information?
Tracing GC involves unpredictable pauses. RC does not (or, at least, has a much lower incidence rate).

They've actually added a ton of settings for the switch to run the Witcher 3 very well: https://www.eurogamer.net/articles/digitalfoundry-2020-the-w...

I basically played it with everything on max and had no slowdowns which is impressive frankly. Obviously rendering on a Switch doesn't compare with a PC - an obvious statement if anyone takes a look a the HW specs.
Yes and no. Not at this price: for 5$/mo you can have a real dedicated server (not a VPS) by kimsufi provider for example.
Also 1 year of rental at 3-4$/mo = you have spent the same price as buying and owning one.
You make some good points, so let me try to better explain where I was coming from.

There are certain games-- the ones that get all the PC gamers to buy new graphics cards when it's about to come out. When there's a game like that coming out soon, I just know it's going to run like shit on console and everyone's going to complain. This was true when Crysis came out in 2007: all the PC gamers upgraded their graphics cards to play it, and the guys on Xbox360 just had to put up with a blurry mess running at 20fps. Same thing happened with Just Cause 3 in 2015. A bunch of others, too.

I don't mean to say that it's okay; if you sell the game on a certain console, one would hope that it'd run well there. I just think it's entirely predictable which games are going to have this problem (it's the ones that got the PC gamers to buy new graphics cards so it would even run), and then I'll hop online and everyone's talking like it took them by surprise.
Being a precise base ten integer suggests it is human derived.

982.000 MHz is the second harmonic of 491.000 MHz, which is the center of Channel 17, UHF Television. It is probably the local oscillator of a broadcast TV tower. Harmonics can be easily generated by any nonlinear process, such as amplifiers or even a rusty contact.
There are definitely worse!
That's not true at all. the big institutions are routinely investigated for this kind of stuff. Barclays and DB for example have had huge fines for various issues in the fx and interest rate markets.

And besides, the majority (if not all, given Volcker restrictions) of sales and trading is from market making, rather than risk taking / directional punts on the markets.
The central claim of the lead essay seems to be that "[The US's] founding ideals were false when they were written". Perhaps you mean "a" central claim?

I’m not pointing to page 47 I’m pointing out that there is 47 pages of the government describing the evidence it has. That’s typical for an indictment. The government doesn’t “in general” refuse to show the evidence. That’s just not how it works.

Grand juries aren’t “known to be tools of the prosecution.” That’s just something defense lawyers and public interest people say. A grand jury is just a group of ordinary people tasked with deciding whether there is enough evidence to even bring a case. The secrecy is there to protect the defendant as much as it’s there for the government. If the prosecutor’s case is weak, then the allegations don’t even become public. Grand juries do vote to indict at a very high rate. That’s because prosecutors only bring cases they know they can win (and indeed they have an ethical obligation not to bring cases they don’t think they can win).

There is a lot of misinformation about how the justice system works. I have seen it from the inside, working for a judge. These cases are buttoned up top to bottom. They’ll arrest a guy for robbing a store. They have him on security camera. They have tracking information from his cell phone. They have his text messages with the guy who he fenced the goods to. They searched his car and found stolen items.

Wrongful convictions are rare. The legal clinics that help wrongfully convicted people actually spend tremendous amounts of time screening cases to find ones that are meritorious. And a lot of those are from the era before DNA testing came into routine use. See: https://dc.law.utah.edu/cgi/viewcontent.cgi?article=1130&con...

> Based on a careful review of the available empirical literature, it is possible to assemble the component parts of a wrongful conviction rate calculation by looking at error rates at trial, the ratio of wrongful convictions obtained through trials versus plea bargains, and the percentage of cases resolved through pleas. Combining empirically based estimates for each of these three factors, a reasonable (and possibly overstated) calculation of the wrongful conviction rate appears, tentatively, to be somewhere in the range of 0.016%–0.062%

Actually property taxes are ad valorem. [..] An ad valorem tax is a tax whose amount is based on the value of a transaction or of property. It is typically imposed at the time of a transaction, as in the case of a sales tax or value-added tax. - Wikipedia[..]

Property taxes are paid EVERY year. What asset do you own that you keep on paying sales tax on?

The real estate market should be stable and for free market forces to aid that, we have to make many more fundamental changes before even touching prop 13.

1. Starting with children and grandchildren who inherit property not benefiting from the prop 13.

2. Secondly, a moratorium on all foreign investments in the real estate market in California.

3. A tiered tax rate for homes left empty while enjoying prop 13 benefits. Additionally, the primary home can also be entirely tax free wrt recurring annual taxes.

California’s problem is not low taxation. Our problem is our state budget and gross mismanagement of our tax dollars by our elected representatives.

I would like to see how they manage our current levies and with more transparency before we hand over a bigger portion of our pay check. If people don’t have disposable income to spend, the economy will crumble and collapse.
Can't quite get my head around their strategy. Can someone clarify? My understanding is that the bought WTI in the TAS market and at the same time sold WTI to drive the price down (It's not clear when did they buy this WTI or if they maded a profit selling them or were just driving the price down). When the price hit –$37.63 at the end of the day the WTI they bought at the TAS market had to pay them, right? That were they made their profit?

> Since this is the US, we have no public transport

What do you mean you have no public transport? Is it cancelled because of covid?
Why not? Life on earth, including human life, has a tendency to sneak into every nook and cranny.

On earth, much of it as I understand is because the “good land” may already be occupied by others, and (initially) less competition in a new place may make it overall less inhospitable than surviving in a fertile but competitive land. After initial generations settle there, future generations will often stay in their native homelands by default unless driven out by other factors. Of course, this is just reasons for settling around Earth itself; who knows what drives the motivations of alien species?
The funny thing is focusing on that will severely hamper your ability to perform in the actual conversation. Outside of gauging the reaction of the specific person you're talking to, if you want to score highly on the "talked for a long time with high confidence and everybody enjoyed it" axis you need to keep your eye on the ball so to speak.
It is not crazy to tax rich I agree, but what constitutes as rich? How do you grantee that tomorrow they will not tax every IT worker who is staying bit longer in California?
I also had this experience. However, I now feel all search engines are returning worse results. Very rarely can I find anything meaningful outside of major content providers. Everywhere my results are filtered through a local government lens. In many ways it feels like search on Facebook, YouTube, Twitter, Instagram, LinkedIn, WeChat, closed appstores, etc. have become the new defacto content aggregation mechanisms, and those are tending toward feeds and curated content rather than requiring active search. The best and most meaningful results on most actual search engine results pages are Wikipedia excepts, or trivial widgets (currency or unit conversion results, weather forecasts, etc.). I don't have any objective measures and am unlikely to be a representative sample but I feel I am searching less, my browser has become a URL-bar based memory system, the traditional 'home page' notion has been replaced by a Firefox auto-curated most-frequent-sites list, and I use traditional search engines more like a command line than a library index. OTOH we now have Library Genesis which is brilliant.

It's true that reputation and trust matter - at least they should. I guess it comes down to the question if a large enough portion of consumers actually know and care about this stuff and would be willing to reward a more open/honest approach enough to actually keep a business running. It might ultimately mean that consumers would have to reward a site/channel that doesn't actually review product X - kind of hard to make a living on that when most revenue ist ad/click based. There might be smaller outlets/youtube channels that do exactly that and use patreon or similar support channels but the bigger sites apparently don't want to bet on that.
There was some sort of attempt by consumers to highlight these issues a few years ago but that was completely curbstomped by the gamergate shitshow.

Those sorts of comparisons are good at making the mechanism or action understandable, but that's about it. The huge thing they miss is if masks only somewhat effective, but people wearing them act like they're moderately effective. The real-world, systemic parts of this is where it gets complicated and interesting.

"In most countries of the world, all mineral resources belong to the government. This includes all valuable rocks, minerals, oil and gas found on or within the Earth. Organizations or individuals in those countries cannot legally extract and sell any mineral commodity without first obtaining an authorization from the government"

In the USA is not exactly liked that but "Property rights and mineral rights were originally tied to the land. The owner owned both. However, mineral rights and property rights can be severed, meaning the owner can sell one and keep the other. So, the original owner of your land may have sold the property rights to one person and kept the mineral rights or sold it to another person. By the time you bought the land, the mineral rights may have been sold already."

So you could be committing a crime by mining gold with only the property rights, you also need mining rights.
