That is a good question. I feel most companies do it out of habit (or because everyone else is doing it) and few have stopped to ask themselves whether the literature in the contract makes sense or not. That was the case at the last company

You could change jobs. An employer tracking your activities to the minute sounds like a cancerous work place to begin with. Bad employers are also a thing, and is much more frequent than most people realize. They usually drown you in tools

I recently switched jobs and now work 35h/week instead of 40. I get a lot more done in those 35 hours now than I did previously in 40. The worst productivity I ever had was in frantic overtime rushes at the end of projects. There'

Same here. They rarely if ever enforce it unless you directly compete with your employer.

Would people who downvote care to explain WHY they're downvoting? Downvoting is a terrible way to disagree with a comment.

It depends on the context. Resuming a request handler after the client timed out is no good. Even in CL in those cases you're fixing at the REPL and having the client redo the request. Or you're developing your function in a sandb

Thanks for pointing this out! I agree about being very careful in choosing to use such libraries! One concern I have is how well they integrate with the native exception system of the VM and what stopping on an error waiting for programmer

> If you want to reason about all possible values, then you are de-facto reasoning about their types. True, but a variable can only ever have one value at any given time; knowing a variable is an int is good, knowing a variable is the sa

Ah yes, Clojure has no first-class support for aspects. Its easy enough to monkey patch definitions for the rare case when its needed. Most of the time however I try to avoid aspects as they introduce hidden behaviour in existing functions,

Which is fixed interactively at the same REPL. You're just restarting a computation instead of resuming it. Rather than recompiling/rebooting the entire program and losing its state in the process. However, this style of developme

Microsoft didn't invent C++, but they started with C which wasn't niche anymore at the time. So you do have a point here. However, you don't see big companies emerging that often anymore nowadays, so that could be a factor as

That's because defn binds f to the _value_ of the function, while (f) binds to the _variable_. > (defn f [] (f)) #'sandbox9672/f > (def g f) #'sandbox9672/g > (def f 42) #'sandbox9672&#x2

That's ignoring the REPL :) You rarely reboot a program under development in Clojure - you rather connect your editor to its network REPL and live code everything from there. This makes not having a condition system a minor inconvenien

Didn't know about ABCL :) You have defprotocol to dispatch based on types in clojure. There's deftype to dynamically create classes and Java has reflection to begin with. You can call .getClass at runtime (which is what the type f

Not overnight, and companies aren't built starting at 15k employees. If you're already at 15k employees then pilot projects are the way to go; gradually incorporate the new tech in the company using low-risk projects. Their post-m

You can feed those types from clojure.spec now :)

Good point! One worry I have about automatic TCO where recur/loop currently is used is with Lisp's dynamic nature. What happens to everyone who has a reference to the fn when you redefine its def? You're basically switching (

That wouldn't be possible on the JVM. CL's condition system is unique to CL AFAIK. Even Emacs' cl module doesn't have this condition system. You really need support from the ground up to have it. Clojure is a hosted lang

I think he meant it in the context of Clojure, which has immutable values. I don't feel static typing makes it easier to reason about, at all. Reasoning about values and their transformations is more important to me than reasoning abou

That works for tail recursive functions, but not tail calls. TCO works for all tail calls, not just the recursive ones, so that jump would be to another function's body. The current stack frame may not have enough space for the new fun

Ah my bad! :) These look very much like Clojure's protocols and multi-methods.

Maybe not always, but its important enough to consider. You often have much more information at runtime than at compile time. Sure I can run the compiler and scan its errors but I feel its much more productive to poke around the program as

Generics aren't dynamically dispatched. Java has type erasure and C# emits variants for every instance.

Its ironic because foo() and (foo) have the same number of characters; but the later is actually data you can manipulate directly. Reminds me of the blub paradox in beating the averages[1]. [1]: http://paulgraham.com/avg.htm

That isn't composition to me but sequencing. Function composition yields a function, not the result of applying the functions. Either you have an object with all of garnish(), strain() and whatnot on it, or each method returns the obje

The epochal time model of Clojure was an enlightenment moment for me when I was learning Clojure. I now sorely miss it when I have to work in any other language :)

The core just uses whatever the VM under it has for error handling. Clojure is a hosted language and one of the best decisions it made was not to hide the VM its sitting on (either the JVM, CLR or JS - all have slightly different exception
