I can’t wait until Flickr and the Yahoo account crap are gone.

Clojure on the Apple Runtime.

20.07.2018 02:00

You can write iOS apps using various different programming languages. You have Swift and Objective-C; and you various ways you can do it with Javascript. There are ways where you can use C#, and of course game engines are used to make the same game for many different platforms.

But I’d love to see Apple extend this. One of the awesome things about .NET and Java(the real kind, not the Android thing) is that the virtual machine or the run time is designed in a way where you can use Java libraries in other programming languages running there, without having to implement specific packages allowing it.

I want to write native iOS and Mac apps using Clojure. Someone else might want to do so using Ruby or even PHP. I have no idea if this is possible with the current iOS or Android runtime, but I’d love it if we moved against a world where all the app development stuff wasn’t so tied two a couple of programming languages on each platform.

REPL

19.07.2018 02:00

A REPL or read eval print loop is what we called an interactive prompt back in the day when I learnt Python and Ruby.

It is a awesome tool when it is combined with the right language. For example, I love it with node or Clojure; but I hated it with Python. And it doesn’t make that much sense with C# or Java.

For a REPL to make sense you need to be able to test small chunks of code. Like this function or this expression; or my typical thing, “would this work” or how the fuck was that syntax again?

In other words, if your language require a lot of “foreplay” to run code, like declaring a namespace and a class etc (I’m looking at you Java and C#) it will probably not be the right thing. But if you can evaluate code without much fuss it is. Another thing that is really important is that you need to be able to just paste code into there. This is something that always drove me nuts about the Python REPL. It is so interactive that everything gets fucked up when you paste crap.

REPL’s are awesome, and can make your development really fast, if combined with the right language.

Life without Dropbox

18.07.2018 02:00

It have gone a while since I got rid of my Dropbox account now. The majority of my Dropbox use was syncing my folder of text files between my laptops and my phone. And I almost never used it on my phone.

Then I started to look into alternatives. The obvious one is to use Git. And that’s what I did.

I have a cron job both on my MacBook and my ThinkPad that pulls, commits and pushes every minute. If there are any changes. And I use Working Copy on my iPhone; for the rare times when I actually need access to my notes when I only have my phone.

It works great, bu the iOS experience could be better. But the solution as a whole is awesome. I can work with my notes anywhere that have git and a text editor. I’m not locked in to any syncing solution or any app. If git isn’t my preferred solution anymore I could change to what the next thing is fairly fast.

Keyboard Maestro

17.07.2018 02:00

I do not know how many times I have downloaded and done a trial of Keyboard Maestro without “getting into it”.

Keyboard Maestro is a power tool that this blog post wont fully cover. But think of it as a tool to do various stuff on a given event. That can be a keyboard trigger, you connect to wifi or that you click “run this macro”. What you do can be all different kinds of stuff, you should take a look at it to get a proper overview. But the stuff I currently use it for is when I want to override default app shortcuts by running Apple Script that does kind of the same thing, but not entirely. Or my work around for the lack of proper batch operations in Lightroom CC. The short version is that I want to “Auto tune” a large collection of images. Typically after I import something etc. The way you have to do this is to open a image, click the button, move one to the right and then repeat. I made a keyboard maestro macro that loops over it a pre defined number of times.

It still takes a long time, but it frees me to drink coffee or beer while watching my MacBook slaving away.

This is the tool you want if you want to do some really geeky shit on your Mac.

Edit for iOS

16.07.2018 02:00

Edit is a great iOS writing app that is about as minimal is it could be.

It reminds me a lot about a app that Patrick Rhone had a role in back in the Minimal Mac / Enough days called Pop (Piece of paper).

The basic idea is that you have an app that is just a large text input area. And that’s it. No sync, no files, or anything like that. This is Edit. And it looks fantastic, has some really cool buttons to make it easy to mark everything and copy it somewhere else.

It might sound very similar to Draft. But they are two different tools for me. Edit is where I write something a little longer on my phone, that probably will require a few “sessions”. While Draft is where I take quick notes and capture stuff.

Edit is very simple and minimal. It might not be your kind of thing, but I love it.

Do you need to know Java to code in Clojure

13.07.2018 02:00

In general: no.

But because Clojure is built on the JVM, you will sooner or later meet an situation where you want to do something where there is a Java Library you can use, but no Clojure library. In these situations you need to use what is called the Java Interop. The code doesn’t look like Java, but it is useful to know enough Java to take an existing example and re-write it into Clojure.

The Blackwing 602

13.07.2018 02:00

I started out with the Blackwing “MMX”, and I immediately knew that I probably should have gone with the 602.

This pencil is awesome. IT is not a “HB”, it is a little bit softer and smother than all of the HB pencils I have used. But it feels like a very good compromise between point retention and smoothness.

Where I usually wanted to re-sharpen my MMX after half a A5 page, this pencil I can get through at least a full A5 before I want to stop and sharpen it. Other than that it feels a lot like the MMX. It is very comfortable to use and is obviously a premium pencil.

The design. It looks really good, even though to colours etc are not my kind of thing. I think both the MMX and the Pearl look much better than the Grey and Gold on this one.

I would probably have liked it to be a little bit harder, but if you are going to use the pencil for writing long form I’d go with this over the other Blackwings.
