OSX GNU Guile — beating libltdl into submission

After encountering an issue with socket handling in the remote REPL server code I needed to build guile from source but it just wouldn’t.

I downloaded a mint latest source from http://www.gnu.org/software/libtool/ and gave it this spell: 
./configure --prefix=/opt/local
to make it overwrite the Mac Porst version to see if that would fix it.
It didn’t.

After further close reading of the configure help text for guile the answer was there as usual, resulting in this incantation: 
./configure --with-libltdl-prefix=/opt/local --prefix=/opt/local

Result… clean run of the configure script!

Now all I have to do is build it and get to the bottom of the problem. Apparently it only happens on OSX, Ubuntu is not affected, nor presumably is any other *nix.
Oddly, geiser mode works, if that is using com-int buffers then I don’t see why I cannot then use telnet or netcat to connect to the REPL server. We’ll see!

It’s got something to do with opening a socket in non-blocking mode then send() thinks the output buffer is full. I’ll spare you the details but just in case you are interested the bug report is here (original), I submitted a new one with lots more information but it’s not on the list yet.

The Coolest Shortest PHP Function I Will Ever Write

Having now released my own programming language, FELT , and learned a lot about this and that in the process I have of late, in the evenings, been struggling to reconcile my love of LISP and how simple FELT makes some PHP coding task leaner and meaner with the fact that I still have to use PHP for my day job. In my language, FELT , I have used the square brackets to define a "normal" array and curly braces to define a "key-value" array, mainly because this is identical to JSON format and anybody familiar with Javascript coding just won't have any issues getting to grips with that now will they! Let's take some simple examples of FELT code: (defvar simple-array [1 2 3 4]) (defvar simple-map {:name "Eric" :age 42 :occupation "Viking Hacker"}) When FELT has done its thing, we get the following PHP code, $simple_array = array(1, 2, 3, 4); $simple_map = array('name' => "Eric", 'age' => 42, ...

Prime Peace

I think prime numbers are the numerical expression of peace. Restful nodes in the vibration of everything. Prime factorisation has always struck me as something truly astounding and it is reassuring to know that awsesome minds are hard at work trying to solve the Riemann hypothesis right now. There are some truly wonderful professional and amateur (in the nicest sense of the word) explorations I have watched recently and the ones that moved me the most, in order of cool factor were: This guy,Carlos Paris, has put in some serious work with AutoCAD and made some interesting observations. I truly enjoyed watching all of his four videos. Awesome work Carlos. As an interested amateur I found his work and thoughts to be very compelling. I am sure the professionals would groan or moan but to me this video is most excellent and informative. Speaking of the professionals, this video is also very interesting to watch as it goes some way to visually explaining the Riemann hypothesis in...

Handling multipart/form-data with NanoHTTPD

I am in the process of reviving an old project from 2014 that I never finished because of other work commitments. In that time, bitrot has set in, the Android API has moved on and all in all, the home-brewed HTTP server I wrote using SocketServer and the org.apache libraries had to go! I looked around, found a couple of contenders and after much time decided to go with NanoHTTPD because it is lean, small and fits in exactly two files. The main server is in one file `NanoHTTPD.java`and there is another file called `ServerRunner.java` which manages instances of running servers. The others The other project I looked at is this one:  https://github.com/koush/AndroidAsync which led me a merry dance and I just couldn't figure out how get the POST data I had uploaded. I spent a few days really digging at it with Wire Shark too to make sure the data was going up. It was. Whatever... I had used it via a gradle dependency entry but I dropped it and went back to NanoHTTPD. For m...
