K7 Tutorial

Man, I want to like J and K but the constant vibe of "this language is so dense and complex, only a few genius programmers will ever understand it" is getting old.

As a companion to this tutorial, the community is building out a clickable version of the k7 reference card. It also covers the current state of Python-k integration:<p><a href="https:&#x2F;&#x2F;k7contrib.gitlab.io&#x2F;docs&#x2F;" rel="nofollow">https:&#x2F;&#x2F;k7contrib.gitlab.io&#x2F;docs&#x2F;</a>

&quot;Customer shall not, directly or indirectly, and shall not authorize any third party to: (i) decompile, disassemble, reverse engineer, or otherwise attempt to derive the source code of, reconstruct, or discover any hidden or underlying elements of the Software&quot;<p>Looks like I don&#x27;t want to spend the effort learning it.

This a typo?<p><pre><code> x: 3 4 5 6 7 8 9 10 y: 100 200 300 400 ?[x;3;y] &#x2F; replace what&#x27;s in position 3 by y 3 4 5 100 200 300 400 6 7 8 9 10</code></pre>

&quot;Shakti k also has primitives for blockchain operations.&quot;<p>That&#x27;s... Interesting. I couldn&#x27;t find any further mentions of &quot;blockchain operations&quot; in the reference. What do they mean, exactly? Since k is traditionally concerned with financial markets, I might guess that they&#x27;re offering deeply-integrated ways to parse transactions, check the number of confirmations, query the current exchange rate, etc.?

What&#x27;s the benefit using k vs. c, cpp or java for the same? Does it run or compile faster?<p>The article says you can do the same with cpp and some extra libraries, but I wouldn&#x27;t immediately think cpp or java was easily beatable -- manjana wonders --

Is shakti related to kx? What is going to happen with kdb+?<p>I also have a practical question. Does `brandelf -t Linux bin&#x2F;k` violate the License agreement?

Does anyone understand if this is <i>fully compatible</i> with Kdb+? been learning q &amp; it would be nice to add vanilla K7 to the list

Whilst One can run j in iOS, j and k are different. May have to try k again.

I wonder what are its improvements over APL?

Can someone compare this to Dyalog APL?

Alternatively, you can look at the completely free www.Aplusdev.org, &quot;A+&quot; language that was also created by Whitney.<p>There is also GNU APL which I have been playing with and has some good ideas also, including the ability to create scripts.
