I somehow feel it is a pitty that Knuth went on to design his own method for describing mathematical expressions, as his seems to less semantic and more based on representation. Note how in his notation the two '_' have a total di

Interesting read. I remember having to implement Unicode support and RTL in a graphic library (based on some version of InkScape, if I am not mistaken) that was code page. I implemented it using Uniscribe. The article 'Uniscribe: The M

Maybe it was not included, because John Conway suspected that it would be Turing complete from the start. Because he suspected this he contacted Martin Gardner and asked the public for searching for an ever growing pattern, resulting in the

The bridge is not in use any more. It has the status of a historical landmark (monument). In 2017 it has been renovated during which the 'bridge' part was removed for some time (years) and the city government promised that it woul

I wonder if this is new. Some weeks ago Nick Drozd, who found a new 4 color, 2 state BLB TM, used this in combination with another optimization (a counter for repeated cells with the same color). This was reported on HN: https://

If I enter the sixteen terms of the sequence A003742 it does not find the exact recurrence equation (with six terms). About twenty years ago, I wrote a program that did find this recurrence equation just from the sequence. If I enter these

At my current job, my second interview was with the CEO and his primary question was: Who are you? And he made it clear he did not want to hear about my education and career so far. We basically talked about our lives. This made me clear th

The related OEIS sequence is https://oeis.org/A000170 . It only gives exact values for n up to and including 27. The value for n = 27 was calculated with the help of an FPGA. See: https://github.com/preusser&

I understand that it uses ImageMagick to do the real work. I implemented a similar algorithm in the script language that I added to my clone of CrystalEdit, after I also added image support to it. The script language has access to points yo

My first wife died as a result of Early-Onset Alzheimer's Disease. From diagnoses till death was 12 years. A much slower process than yours, I realize, which gave me much more time to adapt to it and deal with it. Before she stopped ta

I have the feeling that I have had this all my life. Maybe it is because as I child I was allowed to wander around on myself by foot and by bike. I remember that when I was still in primary school, I often made biking trips going as far as

There is much confusion about the Greek color theory, and I can imagine that for this reason there is also lots of confusion about which word is used for which color. The Greeks with their arts were merely interested in representing humans

In August and September 2007, I spend some tracking all major power lines in the Netherlands using Google Earth. Interesting to see that the information provided on openinframap.org is much more detailed.

I have been analyzing the Turing machine and it is indeed a rather simple loop that implements a Collatz-like function. In the loop a number is divided by two and then multiplied by five where there is a slight difference in the behaviour d

Wikidata is interesting. But it is a centralized approach. Is there an interface which gives the full breakdown of sources and where you can, through a chain of certificates (like those used for ssh and https), verify the sources?

A relational database maps everything to unordered relationships. Representing or manipulating a tree like structure is complex. Just representing an ordered list is complex. In XML and JSON everything is ordered and querying it as relation

SQL is not better than XML or JSON for representing data. They are all mappings of much richer data structures on a limited data model. But even setting aside these problems, there are some problems with a distrubted semantic web that are b

I have always been a little disappointed with both Knuths LP and TAOCP as if they are just missing the point. I feel that he has failed to raised software development from craftsmanship towards engineering. I do not know if he has ever seen

The article is not saying that no code reviews are done, but that it is not manditory. For on boarding code reviews are useful, but you could also do some pair programming or work together on the code.

I solved it without using Dijkstra's algorithm. I simply used a matrix and updated the minimum distance looking at the four neighbours over and over again, until no updates were made. (I have no idea how to do this in Haskell.) It is a

Day 18 was a real struggle for many and over the past days, I came up with four solutions in C++ using different types of data structures, each with their own advantages.

I have come to the conclusion that what happens on the lower-level of the organisation depends on the attitude of the CEO. If he is a persons-first person, this will lickly trickle down to every level. The same as with a results-first perso
