<p>I’ve spent 26 days reading 26 years of messages from the <a
moz-do-not-send="true"
href="/2016/06/09/self-mail-conference-in-mbox/">Self mail
conference archive</a>. Here is what I’ve learned. Please
note, that everything is highly subjective and may be even
wrong.</p>
<h2>Interesting messages</h2>
<p>If you don’t want to go through all 4334 messages of whole
archive, you may read just this dataset, which contains only 295
messages I’ve found interesting enough to save into separate
directory. I’ve saved each message because it answered some of
the questions I had, or because it was marking important
milestone in Self development.</p>

</ul>
<h2>List of alternative languages / interpreters</h2>
<p>When I’ve got to year 2004, I’ve realized it may be valuable
also to store list of alternative interpreters and languages,
which were sent to the conference, so I’ve began to collect them
too. When I finished the reading, I’ve spent an hour by scanning
the 1990-2004 timeframe, but I’ve maybe skipped something.</p>

<h2>Everything is dead, or dying</h2>
<p>Self is small project maintained, discussed and used by only
handful of people over two and half decades (one generation). It
is slow game, and changes may take years (new releases), or
decades (porting to new systems). This leads to massive <a
moz-do-not-send="true"
href="https://en.wikipedia.org/wiki/Link_rot">link rot</a>.</p>
<p>It may not be evident if you are just participating from time
to time, but when you look into archive, it is a clear trend.
Only a few people were able to keep attention and interest over
the decades and maintain resources they created. There were a
lot of those who lost interest or just didn’t have the time and
their resources are dead.</p>
<p>Beginning of the Self conference archive is in 1990, which was
a few years before the HTML and HTTP was invented.</p>
<p>I have no idea, how people organized work and thoughts in
groups at that time (text files via FTP maybe? telephone and
paper notepads?), but it is either converted to a few existing
HTML resources, or (most likely) dead. You won’t see the design
decisions, discussions or thoughts from that time.</p>
<p>Then HTML and HTTP came. People were excited about this new
protocol:</p>
<blockquote>
<pre>From <a class="moz-txt-link-abbreviated" href="mailto:urs@cs.stanford.edu">urs@cs.stanford.edu</a> Sat, 19 Mar 1994 11:53:23 PST:
Thanks mostly to Bay-Wie Chang, Self now has a Mosaic home page,
<a class="moz-txt-link-freetext" href="http://self.stanford.edu">http://self.stanford.edu</a>
All of our material continues to be available via ftp, but the Mosaic
interface is definitively friendlier (e.g., it has an online
bibliography and paper abstracts).
Enjoy!
-Urs
</pre>
</blockquote>
<p>It was definitely an improvement. But idea to create articles
and webpages about Self and put them on your web lead to massive
resource fragmentation. I am not criticizing, merely pointing to
a fact, that almost every link from that time is dead, because
it was not maintained in long-term and that whole situation is
actually unmaintainable by one person, even if that person
really wanted to maintain it. That url in the email is by the
way – <a moz-do-not-send="true"
href="https://web.archive.org/web/*/http://self.stanford.edu">dead</a>.</p>
<p>When you think about it, almost every time anyone counted on
third-party service, it didn’t pay off. From that point of view,
everything is dying, we just don’t see it, because it still
exists. But for the future newcomer to Self, it is already dead.</p>
<p>If you think in the time-frame of decades, all providers of
services will end, often without replacement. Look at geocities
for example. Once it was hosting for hundreds of thousands of
webs. Now it is dead. Sourceforge killed itself by adding adware
to user’s packages, and Yahoo is slowly dying and it is only
matter of time until someone will buy it and shut down most of
its services for good, because it is not profitable. University
pages are chapter for itself, because almost all of them are
dead soon after the person who created them leaves the
university.</p>
<p>Even if the webarchive or other web cache archives the
original, this is not the long time solution. There are various
copyright attack in place right now, which may cause such
services to close.</p>
<p>This may not look like a big issue, but for newcomers, this
means that half of the valuable resources is not available.</p>
<p>If you look at what survives, it is almost always only files
which were downloadable and thus shared by large number of
people. In this sense, git is the best solution, because it
allows everyone to clone the repository and synchronize it with
others, even if the original resource is gone.</p>
<p>There is two possible options on how to overcome this problem:</p>
<ul>
<li>distributed standalone information resources shared by
everyone</li>
<li>maintained centralized group resources</li>
</ul>
<p>If you create your own webpages, make them easily downloadable
and sharable. Otherwise, they will be dead soon (5-20 years from
now). Other option is to write articles in postscript / PDF and
generally standalone files, which will be distributed to large
number of people.</p>
<p>Second option is to make central repository of knowledge
consciously maintained and hosted over the years by Self
community at one place. Preferably in the form of Wiki. I will
get back to this later.</p>

Subject: non-official ftp site in germany (solaris only)
The link speed to Sun was really not acceptable when I tried it, so I was
glad to be able to get Self from Manchester. Seems that I have been lucky
now that the site is down. The FTP admin of our local computing centre was
so kind as to put Self 4.0 on his server. It is not official and may
vanish any time, but they have lots of disk space and I suppose it won't.
Still, please don't use this site unless it is a lot faster than your link
to the USA.
Since the stuff is the one that I used to install Self here,
it doesn't look exactly like the original (all files have the Self-4.0
prefix) and it is not complete (I only installed the solaris version).
/ftp.gwdg.de:/pub/languages/self:
total 12110
-rw-rw-r-- 1 emoenke 1475 Jul 26 17:05 Self-4.0.Install
-rw-rw-r-- 1 emoenke 1933 Jul 26 17:04 Self-4.0.LICENSE

-rw-rw-r-- 1 emoenke 12320062 Jul 26 14:16 Self-4.0.solaris.tar.gz
Also, the tar file is gzipped instead of compressed. Not having patched
the install script, it won't work anymore (unless you linked zcat to
gzcat), but what Install actually did was just a single line anyway:
gzip -cd Self-4.0.solaris.tar.gz | tar -xfpB -
Greetings, Rainer

Assumpcao Jr</a> is my new personal hero.</p>
<p>Not only that <a moz-do-not-send="true"
href="http://www.merlintec.com/">http://www.merlintec.com/</a>
still works and didn’t lose any of its contents, also his
messages on various topics in the conference were really great
and it was pleasure to read it.</p>
<h2>Self is really complex</h2>
<p>There is 114 821 <a moz-do-not-send="true"
href="https://github.com/AlDanial/cloc">cloc</a> lines of C++
code (counted without comments, blank lines and so on). There is
two kind of compilers (NIC, SIC), assembler and other
platform-dependent stuff. Almost none of it is documented
outside the code itself.</p>
<p>This is bad. Really bad. I did a little bit of C++ back in h<span
id="result_box" class="short_text" lang="en"><span class="">igh
school</span></span>, but I can’t really imagine going
through all this code and trying to make sense of it.</p>
<p>It is extremely hard to get an idea what Self really is, what
parts is it made from. Best thing documenting how Self works is
this schema from the handbook:</p>
<p><img src="cid:part9.06060400.04070009@kitakitsune.org" alt=""></p>
<p>We need pictures like this that will document components of the
VM. Schematic blueprints for what Self is and how it
approximately works. Sometimes, pictures says more than a
thousand words.</p>
<p>If you don’t think that this is serious, here is a list of
reasons:</p>
<ul>
<li>It is hard for beginners to even get the idea what Self is.
We know, that it is a language, but it is also virtual
machine, bunch of compilers, memory managers and what not. It
is almost like small operating system.</li>
<li>It is hard for anyone who wants to contribute to get an idea
where to do the change.</li>
<li>It is hard for anyone who wants to port the Self to another
architecture / OS.</li>
<li>It leads to fragmentation. People rather create own forks,
or whole new languages rather than to try to make sense in so
much C++ code.</li>
</ul>
<h3>Linux</h3>
<p>An example of the complexity of Self was its porting to Linux.
First message about porting to Linux was probably this:</p>

Hi,
I have recently read about Self and ftp'd some papers from self.stanford.edu,
I even got the sun4 version of Self 2.0 and played around with it for a few
minutes. Otherwise, I have no experience with Self whatsoever, but from what
I read I am kand of enthusiastic.
My question: Is anyone porting Self to some other platform, maybe even to the
386? I have Linux running on a 486/33 w/ 16 Meg RAM and 500 Meg HD, which should
be a workable system for Self; I have gcc-2.2.2 and libg++-2.2, so it should be
possible to compile the virtual machine (judging from the README's).
BUT: I have the feeling that the compiler really generates native SPARC code and
so one would have to write a completely new backend and assembler for the 386.
I guess that would be a *major* project!?? Is the compiler/assembler written in Self
or C++? If Self is tied to the SPARC achitecure and inherently non=portable, then
that would nagatively influence the impact that this exciting software could have.
How about using the gcc backend?
Thanks for any info,
Dirk

<p>This is from 1992. First (not fully ported) Self for Linux came
in 1999, by <em>Gordon Cichon</em>, but that wasn’t really much
usable, from what I’ve read. Proper support with GUI and
everything working nicely took several more years.</p>
<h2>The bus factor is low</h2>
<p>As the <a moz-do-not-send="true"
href="https://en.wikipedia.org/wiki/Bus_factor">wikipedia</a>
says:</p>
<blockquote>
<p>.. the bus factor is a measurement of the concentration of
information in individual team members. It .. connotes the
number of team members that can be unexpectedly lost from a
project (“hit by a bus”, as it were) before the project
collapses due to lack of knowledgeable or competent personnel.</p>
</blockquote>
<p>The bus factor of Self is incredibly low. From my own estimate
based on reading the archive, I would say it is 5, maybe 7 if
you want to be optimistic, probably 3 if you want to be
pessimistic.</p>
<p>This is not just bad, because it threatens existence of Self
alone, but mostly because it also means that there is extremely
low number of people, who <i>really</i> understand Self, and
almost no documentation, which can train new experts.</p>
<p>Wikipedia offers following solution to increase the bus factor:</p>
<blockquote>
<p>Several ways to increase the bus factor (thus making the
project more resilient) have been proposed:</p>
<ul>
<li>Reduce complexity</li>
<li>Document all processes and keep that documentation
up-to-date</li>
<li>Encourage cross-training.</li>
</ul>
</blockquote>
<p>I don’t think, that there is much space for reducing the
complexity, but second and third point may be solvable by
community Wiki.</p>
<p><a moz-do-not-send="true"
href="http://www.ywamkb.net/kb/Bus-Factor_-_Avoid_to_depend_on_a_single_person">YWAM
KnowledgeBase</a> also mentions two more interesting points:</p>
<blockquote>
<ul>
<li>maintaining documentation about how the corresponding
website is working</li>
<li>forum for learning from each other</li>
</ul>
</blockquote>
<p>Again, both points may be solved by community Wiki. Especially
the second point is really important.</p>
