It happens a lot for me. Basically you have to choose between copy-pasting a lot of sql code or trying to reuse parts when the business logic has multiple cases that are similar but not exactly equal.

SQL was often combined with Cobol (might still be where they have Cobol).

They don't write if they looked at other databases. I think there are a lot of alternatives that might have worked better for them than MongoDb and even Mongo 3.0 might have worked better. Regarding the schemalessness for simple new pr

Micro ORMs usually works very much like this. There is a problem when you want sub records, they are handled differently in each library or not handled at all.

They explain that, they are aiming for faster execution and less bugs. Faster execution requires that the VM and the language changes. They tried this with Dart but that hasn't become popular, now they try again with something differen

The ES6 class system seems to be done to feel more like java and c# without regard for the mixin/prototype parts. I'm glad React still works with mixins. (edit spelling and clarification)

Yes, some parts are just basic structuring. Breaking an application into services, knowing what parts are singletons and not and finding ways to communicate between parts. If AtScript/TypeScript is used more you can use those skills in

Sounds like he wants Web Services with json. If he just comes up with a name other than REST he can use it for anything he wants, it would be silly to use the name for something where you clearly break all the rules/guidelines. And I d

But a change of language might bring you more tools, for example to handle thread-pools or process pools (service worker pools). Some of these things might be much easier to do in Go (or Java or C#) than in Ruby and if that part was a reaso

It almost means the same. Node is using V8 (from Chrome). Not sure if Nashorn has any asm.js optimizations but it will probably get it later if it is important to many organizations. Those are probably the most commonly used js engines out

I think they went too tiny. There is almost no info about possible chart types or what you can do. The download feature is nice but that's all I can see right now. Havn't looked at the source code. I think Plottable looked like a

You should always know your audience. The problem I feel is that some recommendations says something like "always make apps that work without javascript". If you know that about 99% of your users have javascript that may cost a lo

Of course people are more important than tools but that doesn't mean tools are unimportant. In same cases the tools are VERY important. There are for example things that are easy to do with javascript that are impossible or almost impo

I think one big problem is the expectations. People think that they can learn a lot of programming in 3 months or 1 year or something. I think it takes a lot of time, unless you happen to be "hardwired" for it. As someone wrote th

The short version: scaling horizontally means getting many more boxes scaling vertically means getting a bigger box (replacing the one you have)

But he doesn't mention a lot about alternatives. Of course we could try to avoid having a single solution for everything but if there is no better option right now then REST can and should be used. If his point was to say that REST onl

It's not just the browser, people often want to create mobile apps today and there is no standard language that works for all platforms (you can try C# with Xamarin but it is not the native choice of all the platforms). And there is no

I totally agree but when they what to use the disk it requires NodeJs or similar and then you can wipe the disk again. But it easy to start safe.

It sounds a little bit like BizTalk :-)

It still depends on what programmers you ask. Windows works fine for me, Linux did not work well when I tried it (but it was many years ago). Unix through XWindows from a pc was actually quite nice. I think developers like users use feeling

I think they have issues all over the chart. We've had severe problems with changes in Safari's handling of javascript. Other have had problems with network connections etc. There seems to be a number of problem in many places.

I think the article said that you don't need to use Hadoop for everything and that it might be much faster to just use command line tools on a single computer. Of course you might find a use case where the total computing time is massi

Oracle seems to spend some money on java and JRuby which is pretty fast and will get even faster the coming years. Not sure how much if any they are directly funding JRuby but they are funding the JVM which is used by JRuby.

It is usually the loading of many resources (js etc) that takes time. If you just send some html (and css) to the browser it can show it quickly. But companies like Facebook and Airbnb are starting to send html first and then use javascript

Then we should probably compare other NOSQL solutions to relational databases. Like CouchDb, CouchBase, FoundationDb, Neo4J, etc.

Document databases normally has atomic updates of a document. This may contain many parts and would require transactions in a relational db. Meaning you kind of get some transactions automatically. Other things are not possible to make tran

Nowdays they actually go javascript (Node) on the server for a lot of performance things. It is really fast for some things.

He specifically mentions performance many times but has no statistics to back this up. I have created a web app with Angular and it runs fine on old Android phones and iPhones. We don't see any performance problems. Of course YMMV but
