I think many people are satisfied with the alternatives presented in that thread. A very large percentage will probably even be happy with the serialization to Lists and Maps - because that is what JavaScript already does! I understand that you have your preferences, and you are entitled to have those. In my opinion, you are not entitled to:

- Present your complaints as though Dart is missing basic functionality (not in the presence of the presented alternatives). It just misses your specific desired functionality!

- Assume your use case is representative for a significant amount of other developers.

- Extend your entitlement to the HN front page.

C# JSON support appears to be awesome, and you are very free to make a Dart library that does exactly that. You are also free to request it to be merged into the core Dart libraries [1]. You are not free, in my opinion, to drag out this complaint so much.

As a reference, here's a list of other typed languages that don't support JSON deserialization-to-classes in their core libraries:

- Java (Scala, Groovy, Xtend, etc...)

- GWT Java

- Kotlin (both on JVM and in browser)

- Ceylon

- C++

- OCaml

- Swift

- ...

Seeing those languages are often used to consume web services, it seems Dart is in good company. There's probably a good reason why this stuff is relegated to third party libraries. I'd speculate that 1) accomplishing this is messy and complex in the context of type safety and 2) the problem you are complaining about simply isn't as big as you think it is.

Creepy Photos of Russia’s Crumbling Communist Architecture
Depends on your definition of "supported"? JSON uses maps (throwing away one of the big advantages of Dart) and the Serialisation package appears to rely on hard-coded rules or use mirrors (which are slow and apparently not a good thing to use in production dart2js code).

There is a lot more to stopping an epidemic than creating the drug. You also need to be able to administer the drug--and in some of the areas worst-hit by the current outbreak, residents are suspicious (or actively hostile) to medical teams.

Ebola transmits through direct contact with bodily fluids, which means that basic measures of sanitation and hygiene can go a long way toward slowing its spread. If those cannot be achieved, distributing an expensive, delicate drug is not likely to be achievable either.

What are people doing with their taxes to need a significant number of receipts at tax time? The two largest cases I know of are business expenses and charitable donations; the former doesn't apply to the vast majority of people, and for the latter, do people really have so many of those receipts that they can't keep up with them?

And in both cases, you wouldn't need the receipts at tax time, just the amounts; you'd only need the receipts for a possible audit.

In many peoples opinions, it is. Your opinion is no more fact than mine.

I can assume what I want. I believe it's true. It might not be; but it seems like a pretty basic requirement; and there are many other people in that thread that share the opinion.

> Extend your entitlement to the HN front page.

I didn't put it there, the people did.

> you are very free to make a Dart library that does exactly that

That's the whole point - there is no sensible way to implement this from the outside; that's the whole point of my thread. All of the ways of achieving this suck for one reason or another. Doing this well needs better support from the language/Dart tools.

> the problem you are complaining about simply isn't as big as you think it is

I've still yet to see anyone anywhere post a small code sample showing a Dart class and some simply JSON that works, without a hand-coded mapping from a Map. Is this really what we should be spending our time doing using Google's "new language for the web"?

Sysadmin who was tricked into taking a fight cross-country to get control back?
I read an article a few years ago, about a sysadmin who had been discovered to be running a private (porn?) server on his company’s servers, but also had sole control of system admin passwords. The really interesting bit of info was that the company execs had to trick him into taking a “business-related” cross-country flight, so they could keep him from monitoring the systems/deleting evidence long enough to reset passwords. (Obviously in the pre-Bongo age.) Not having any luck with the big G - anyone remember this story?

I don't know the whole story, but there is (or was?) an organization called the Gasoline Pump Manufacturers Association that dates back to at least the 1930s, which seems to have some role in it. Also quite a bit of government involvement, since the measuring parts of the pump fall in the category of "weights and measures", which have been regulated since quite early in U.S. history as an anti-fraud measure (e.g. butchers were traditionally required to use an officially certified scale).
That one looks nice!

The moto of Dart is to make the life easier for developers.

I think that moto doesn't fit Dart at all, I use Dart and I have to make some workarounds that I just shouldn't be doing, but I have to because the language doesn't have the functionality that other languajes already have. The problem I see is that the Dart language developers never put them self in the shoes of the developer using their languaje.

In this case, I would be easy for them to add JSON serialization to objects, you know, but they didn't, why? polictics, apathy, whatever, but not technical problems.

So, my self, had to adapt to programming in Dart, so I every class must have a toJSON and fromJSON methods where I manually put the values to a map and then I use convert.JSON. But, I now I gave up using classes and now I just use Maps, just to write less code and is already the type Dart suppor for JSON serialization.
This is a great idea, although repr() would probably be better than str().

I've spent a lot of time debugging Python over the years. This honestly never occured to me until you mentioned it.

Edit:

Everyone else jumped in before me. I think it would be useful as a command line switch to python to turn on the behavior (maybe call it extended exceptions).

Python would need to run the extended exception generation under a try/except that fell back to regular exceptions if an exception was raised while calling repr()

How to name your price. The secret formula for setting up your hourly rate
Side Note: Slick has basic parameterized queries/statements/DDL.

eg:

val cachedPurchasesQuery = Q[String, (Int, AccountId, Timestamp)] + """
|SELECT pi.purchasable_item_id, u.account_id, pi.created_at
|FROM purchased_items AS pi
|INNER JOIN users u ON pi.user_id = u.id
|WHERE purchasable_item_type = ? AND u.account_id IS NOT NULL
""".stripMargin

Then you call that like:

val magazinePurchases = cachedPurchasesQuery("Magazine").list

Or `foreach`, `firstOption`, etc. Most of the normal collection-y stuff.

I prefer this over the Table mapping DSL and for-comprehension stuff personally. But I've only used it in production on smaller projects that are limited to under a dozen queries/statements or so.

It's disappointing to me that this needs to be said. I read the first Song of Ice and Fire book in the middle of 2013, and I finished the fifth book this past March. That's several thousand pages of fiction in less than a year. Clearly, I like the books.

But I can wait for the sixth book. I did fine in 2012 without ASOIAF, and I'll do fine in 2015 and 2016 and even 2017 if it comes to that.

Last year I discovered I prefer novels and assorted nonfiction to reading random articles on the Internet. I prefer to chew on one idea for a long time than a thousand little ideas at once.

So what I'd really like is a way to find other books to read that I enjoy as much a Martin's work. I've signed up for GoodReads, but nothing has come of it just yet.

> If you are taking data out of a relational database and mapping it into objects, you are implementing an ORM.

No, ORM is a particular approach to doing that; the query abstraction approach described upthread is closer to the DAO pattern, to which ORM is an alternative. People were using RDBMSs to provide a persistence layer for OO programs before ORM was a thing, but as you have broadened the term any use of an RDBMS to store/retrieve data used in an OO program would be "ORM".
Doesn't seem like a showstopper to me; just fall back to current behavior if str() fails or takes too long, and truncate if it's too verbose.

I like looking at John Scalzi's "Big Idea" section where he lets other authors talk about their books on his blog. Find it here: http://whatever.scalzi.com/category/big-idea/
The one thing I like about ORMs (where I control the ORM): I can prevent any SQL query from being run that doesn't have a WHERE statement.

Especially when dealing with anything that changes data, lack of WHERE is very dangerous.

That said, I write raw SQL. It's the only way to get the performance. As an abstraction it's already great and I don't feel I need another abstraction on top of it.

An example of the kind of query that an ORM is bad at:

SELECT id
,value_from_row_based_functions(some_column) AS foo
FROM bar
WHERE some_column = 'blah'
ORDER BY id DESC
FETCH FIRST 25 ROWS ONLY

It's bad because the ORM will merrily do this even though the row based function may be expensive. Over hundreds of rows this isn't an issue, but over millions or tens of millions it kills your query (if it doesn't timeout it will merrily carry on for hours).

Good SQL always reduces the amount of work involved, you tailor it as you would your regular code to avoid doing work that isn't needed (reading rows you will discard through a filter, etc).

The above could be written as:

SELECT id
,value_from_row_based_functions(some_column) AS foo
FROM (
SELECT id
,some_column
FROM bar
WHERE some_column = 'blah'
ORDER BY id DESC
FETCH FIRST 25 ROWS ONLY
) AS something

And now the row based function is only applied to the 25 rows that are going to be returned.

If you look at the very bottom of this: http://www.postgresql.org/docs/9.2/static/textsearch-control... you'll see this is a real-world problem.

ORMs can stitch together your SQL in a certain way that is fairly optimal for most common scenarios... but you will encounter a scenario in which raw SQL is the only way to go.

Union/non-union may not seem like an issue inside SpaceX, but the view from other workers in the industry may not match that. Last month, I was at a 4th of July party which happened to be mostly space workers, and when I brought up the subject of SpaceX the consensus was, 'Cool company. I'd totally work there if the salaries weren't so low.' It surprised me, since I tend to associate up-and-coming companies with money from the Valley with higher salaries.

I enjoy the musings of the contract between writer and reader. If the author doesn't agree, on some level, to finish the series and it's the reader's requirement that a whole series must be read, then the reader is left with no choice but to wait until a series is finished before beginning. In various degrees of depth, we enter into obligations to others by beginning something, whether writing a book, having a child, ordering food etc. Seems the blog author's opinion is that GRRM has no obligation to his readers. I'd argue he has some form of professional obligation, but certainly no contractual ones w/ recourse.
