In various places on the web one can find the quote that 'Dependency injection is a 25-dollar term for a 5-cent concept'. I feel it is the same with monads including all the false suggestions that one might need to understand cate

I completely get where this person is coming from. The distinction between maintenance and producing new features on one side and paying down technical is so strange. It does not make very much sense to start working on a piece of the code

I think most disenchantment with TDD comes from the second point that you notice. If one attempts to test every method of every class one ends up testing implementation details that are very much subject to change. Also, one can easily end

It is an improvement over the current situation but the question remains what these journals are good for besides gobbling up money that should go to research instead. There are preprint servers. If they can create a comment system where sc

This is one thing to try to find out when one applies for a job. What kind of stupid requirements are there and is this company prone to senseless prescriptions? Even if one thinks that a particular senseless prescription is not very burden

Hmmmm.... I think the main problem with git submodules is that if you google 'git submodule' you don't find anything useful. When you somehow discover how they actually work they are... uhm... let us say... 'usable'

100% correct article. The compiler/runtime does not care if all of your variables are global and all functions modify all of them. Almost all program structure is there for humans and not for computers.

I think there actually are bad styles. The google style guide is such a bad style guide. The combination of 2 spaces indent and not putting { and } on top of each other makes it difficult to see at a glance where a block begin and ends.

Well if vector<SomeType> is used in many cpp files it is compiled separately for each and every one of them and then the linker throws away these gigantic amounts of code duplication between the various object files. Also vector<sh

It is very easy to prove. Note first that ~P is an abbreviation for P -> False. So we can rewrite this as (~ ~ P -> False) -> P -> False. This is tautologically true by modes ponens if P -> ~ ~ P. But that is a well known fac

Actually, the thing that is excluded in constructive mathematics is ~ ~ P -> P. ~ ~ ~ P -> ~ P is a theorem also in constructive mathematics.

I think it is pretty obvious. An ideology is something that has a very narrow set of answers to every problem. It can easily preempt much or even any actual thinking. On a forum one can easily end up in a screaming battle between ideologies

Regarding the use of the 'aggressively conventional minded'. When I was younger I would think that these kind of people were mostly just detrimental to society but I have come to see that they sometimes have a use. It is this kind

It can also help a lot if you log all incoming/outgoing packets in a format that allows replaying the session.

The ludic fallacy could apply here as well. If you calculate that on average you will make a profit but in actuality this profit fluctuates so wildly that you will almost certainly go bankrupt in the process the ludic fallacy could apply. A

C.G. Jung once wrote that the moral capabilities of a group of people is 'obviously' inversely proportional to the size of the group. C.G. Jung was a funny guy. He would write a controversial statement and prefix it with something

This may be the case for you but these kind of things are very much dependent on the person. One thing is to accept that not all items on various lists will be finished. The book explicitly says this is the case and recommends to remove ite

This seems to be assuming that the neutrinos are massless, or at least have a mass quite a bit smaller than the Z particle. It could be that there is a fourth generation where both lepton and neutrino are heavier than the Z particle, no?

No, it is not overrated. The author is just using a not-so-handy definition of 'unit'. When a 'unit' is a single method/class/function 'unit' testing is not in general a very wise thing to do. In most

Identifying the good developer with the frequent job hopper and the expert beginner with the developer who stays at the same place seems rather unfounded. I have also seen the job hopper who left just before it became clear that his archite

Clear code needs some comments. Not many, though. If you write a numerical algorithm it probably needs an explanation or a reference to where it came from or something like that. Generally, one needs a comment when it is difficult to figure

Actually, I have in fact seen this. I worked at a place where this copy and paste programming actually lead to functions that are many thousands of lines long and are full of duplication and very deeply nested. At some point a file was spli

If there is one single article about programming that I hate it is this one. It is completely the wrong message. One should instead be very eager to eliminate duplication. To avoid the pitfalls that the article notes one should create abstr

Things like lisp, forth and also lambda calculus are conceptually clean. In theory one can write anything in them in a conceptually clean way. However, doing so one has also puts programming and/or computers in a straight jacket which

The only thing that somewhat makes sense is that during exploration TDD may not always be the most practical. It immediately starts to be extremely practical once the exploratory phase is over. I kind of feel you live in some kind of altern

This is clearly wrong. If you put your pinky finger inside the hand of a baby s/he will grab it and hold it. This can be seen very early.

You should immediately stop designing for future use cases. Use TDD and only write only just enough code for the currently known required functionality. When you get to know more required functionality the tests protect you from breaking ex

Kind of agree and also kind of disagree. For some things there actually are recipes. For instance, I greatly benefited from learning GTD (getting things done) at some point. Not having any sort of overview of all the things going on in my l
