When your system is replacing some existing system, which could well be just paper-based, it is very useful to study it carefully. It will give you a good idea about the data and its internal relations. If you want to show something to a customer, you can also simple mock-ups like static HTML pages.

Only after you have a decent understanding of the system you should start building it. There will be many new requests, but most will just be concerned with the UI. If you have the right data model and architecture, those will not be very difficult to solve.

Against SQL 5 years ago

With an AOT compiler a lot of work is done at compile time, but with JIT it is done at runtime, which makes these programs slower to start. But for programs that do run for a longer time, like servers or IDE's the performance is quite decent. But Java is a memory safe language which means that it has to do a lot of checks that unsafe languages do not have to do, which means that it will always be slower that unsafe languages. In some cases the JIT can eliminate those safety checks, but that is not always possible.

Java always had (and still has) an AOT that compiled to byte code. Adding JIT was a major improvement.

We certainly do deserve better, and the author made some good suggestions.

Unfortunately, building a new database is a huge project and there appears to be no party currently willing to sponsor it.

Against SQL 5 years ago

An example here is how, sure, in theory, JITs can outpace AOT compilation because they have all the information the AOT compiler has plus runtime insights. But the ability to truly do that always seems to be a decade of compiler development away, with many giving up on the idea entirely.

JIT has been used very successfully for a couple of languages, e.g. Java. But adding it requires a lot of effort. The same thing is unfortunately true for new query languages, building a new database is really expensive, this is probably the main reason that there have been no serious alternatives to SQL.

My country, the Netherlands, has been struggling with water for its entire existence. A large part of it is below sea level.

In most parts we have two different drainage systems, one for rain water and one for sewage. All sewage is processed in treatment plants before it is released into open water. We don't use open water directly as drinking water. Either we use ground water or use river water that has been infiltrated into our dunes.

There are probably some things that the US could learn from this, but it will probably come with a very high cost.

One of the big problems with "modern development projects" is that they start coding from day 1. The first step in any good project should be to learn as much as possible about the requirements before making serious decision about its architecture. Designing a model of the data (even if it is only a very rough one) is usually very helpful in the first phase of a project.

It is still true that mistakes that are made during early phases of the project are much harder to fix than recent mistakes.

When there is good public transportation the need for cars will decrease. Also when buildings increase in density, public transportation will become more profitable.

South Korea is a fine example where this worked. The cities are very compact but have excellent public transport. It will be difficult to achieve something similar in the US.

The fractal shapes are really beautiful, but the other beautiful thing is the species to which it belongs.

We have many vegetables that are really just different forms of the same species Brasica oleracea [0]:

    Brassica oleracea Acephala group – kale
    Brassica oleracea Viridis group – collard greens
    Brassica oleracea Alboglabra group – kai-lan (Chinese broccoli)
    Brassica oleracea Botrytis group – cauliflower, Romanesco broccoli, and broccoflower
    Brassica oleracea Capitata group – cabbage
    Brassica oleracea Gemmifera group – Brussels sprouts
    Brassica oleracea Gongylodes group – kohlrabi
    Brassica oleracea Italica group – broccoli
It's amazing that we can cultivate a single species into so many different types of food.

Some people hate each and every one of these varieties, that is probably due to genetics.

Claims about some of them being "super foods" are nonsense, but they are all pretty good food sources.

You really should not cook them too long. Then they start smelling and tasting pretty bad.

OK, that got down-voted. I thought the basic idea behind HN is that we can have some interesting discussions. Simply down-voting without adding a reply why you disagree with an opinion does not really help.

I have been interested in security for a long time. The number of security vulnerabilities that have been caused by insecure memory management problems is really huge. Some people will probably claim that this is not a problem with modern C++ because it can remedy this problems. But this assumes that the programmers know all the possible pitfalls. With respect to security, the problem is that when there is only a single weakness in your system it might become a point of attack. With a language like C++ there are many possible weaknesses that simply do not exist in memory safe languages.

But I really wonder if that happens frequently. Cigarettes really taste and smell awful. I discovered how terrible they really are only after I quit smoking. As long as e-cigarettes remain available, I doubt that many people would switch to real cigarettes.

I really don't think it was a good idea to write this in C++ for security reasons. It accepts external inputs in some complex formats, and they also have a web server version. This makes it highly vulnerable to all kind of attacks, such as buffer overflows.

beating the previous national high temperature mark by more than 4C in one go, as happened in Canada last week, is virtually unprecedented.

This event should be a warning call to all people who believe that a global warming of only 2 degrees Celsius will be barely noticeable.

One positive effect is that scientists have collected a lot of data that will help them improve climate models.

And scientists who feared another Spanish flu did not know that the 1918 influenza was avian, not swine

Because swine are really similar to humans, I see more reason to worry especially about their viruses. They are likely to have multiple adaptations to our own bodies.
