Notes:

I am an open-source user and developer, but don't really have anything against commercial software, if written and maintained well. I am an active member of the Israeli Group of Linux Users, the Haifa Linux Club, the Tel-Aviv Linux Club and numerous open-source related mailing lists.

My favourite programming language is Perl, but I also like Haskell, Matlab and Bash where appropriate. And I have a love/hate relationship with C/C++.

So far, my most ambitious open-source project has been Freecell Solver, but I also wrote or contributed to some other projects and hacks.

I received a B.Sc. from Electrical Engineering from the Technion, and am now looking for a good job in IT.

Google Announced It Will Discontinue Its Web Search, Gmail And Google Docs Services

1 April, 2014, Tel Aviv, Israel: Google announced today that following its popular decision to discontinue not-so-popular services such as Google Reader, it is going to discontinue other services such as Google Web Search, Gmail, and Google Docs.

“These services have been suffering from declining use and popularity”, a Google spokesman said, “as a result, Google decided to discontinue them in order to remain profitable.”

Google Web Search is disabled: “Not your lucky day”
The New Google Web Search front page.

After discontinuing these services, Google will focus on more profitable ventures such as version 9 of V8, its open-source JavaScript engine (= "v8 v9"), and its mobile operating system, Mandi the Womanoid. It is also going to provide its world-famous customer service as a service to other companies (“Google Customer Service as a Service” or “GCSaaS” for short).

The same Google spokesman also noted that Google is considering to discontinue Google AdSense and AdWords, because they too are proving to undermine its profitability.

The Free Software Foundation (FSF) Announces New Versions of the GPL

1 April, 2014, Tel Aviv, Israel: “FOSS developers don’t have enough choice when it comes to licensing.” says the Free Software Foundation (FSF). Thus, in order to contribute to the noble cause of licence proliferation, it announced new versions of the GNU General Public License (GPL).

The FSF announced the GPL version 4 (GPLv4), GPL version 5 (GPLv5), GPL version 6 (GPLv6), as well as the GPLv7, the GPLv8, the GPLv9 and the GPLv10 — all with their LGPL (Lesser GPL), AGPL (Affero GPL), and LAGPL (Lesser Affero GPL) variants, and all mutually incompatible with one another and with the GPLv2 and the GPLv3 (which are in turn now deprecated).

GPL v3 is out! Now it's GPLv4, GPLv5, etc.
The New GPL logo now that GPLv3 was deprecated.

In addition, by popular demand, the FSF introduced some often requested variants of the GPL: Strangely-enticing GPL (SEGPL), Diamond Encrusted GPL (DEGPL), Zebra Flavoured GPL (ZFGPL), Objective GPL, GPL++, GPL Enterprise Edition (GPLEE), Industrial Strength GPL (ISGPL), GPL for Dummies (GPL4D), Unusable GPL (UGPL), GNU Passive Aggressive Public Licence (GPAPL), Proprietary GPL (PGPL), Non-Free GPL (NFGPL), and I Can't Believe It's Not The GPL (ICBINTGPL).

The Free Software Foundation is also going to introduce one GPL licence each day in an effort known “Daily GPL”, where each daily GPL breaks compatibility with all the previous daily GPLs. As an FSF spokesman said “We hope that soon there will be more versions of the GPL (“GPLs”? Hmmm…) than GPL-licenced software”.

The GPLs’ proliferation has met with some positive responses from organisations who need to deal with them. The administrators of Freecode, a releases announcements and cataloguing site for UNIX software, noted: “This initiative is threatening to make the database table holding the possible options for software licences larger than all other tables. We’re contemplating to just consolidate all these licences under one option of ‘Under one or more of the FSF so-called-‘GPL’ licences’.”.

In the meanwhile Linus Torvalds had this to comment: “I always was a big fan of version 2 of the GPL, but the new FSF licence The Positively-Awesome Make-Yourself-At-Home Fine-Grained-Control World-Domination-At-A-Snail’s-Pace GNU General Public Licence (GPL) from 2014-04-01-10:35:49 up-to-and-excluding 0123-04-01-01:55:09 seems like such a sexy licence, and I’m considering adopting it (after I implement some custom changes to make it more to my liking.). Good thing it didn’t take the FSF too long to come with a half-decent alternative to the GPLv2.”.

The Logo was created using Inkscape based on the SVG in the GPLv3_Logo in the English wikipedia (which is in the public domain but may contain trademarks), and modified using Inkscape by making use of “Mail Ray Stuff” font by Ray Larabie (found on dafont.com), which isn't a libre font, but its licensing terms seemed usable and acceptable for this purposes (and it is available for some kinds of commercial use).

Tech Tip: add a notification (or any other command) after a command-line task has ended


I discovered that one can add a notification after a command you've already
started running has ended on a UNIX system by suspending the command
using “Ctrl + Z” and then typing something like
“fg ; n --msg 'Command finished'” (where “n” is the command I use for
notifications). “fg” brings a job to the foreground, and for more information
about it see
its wikipedia
entry
and the Unix Background Jobs entry on thegeekstuff.com.

Tech Tip: Resetting the GLib/Gtk+ Default Apps on Linux (e.g: the Default Browser)

In this tip, I would like to describe how to reset the default apps, and especially the default browser, for GLib and GTK+. These are used by desktops like GNOME and XFCE, and by GTK+ applications such as HexChat or claws-mail. My problem originally was that I accidentally pressed the "Yes" button when Firefox Nightly (installed under a prefix under /opt) asked me whether I should set it as the default browser, which caused HexChat and Claws-Mail to open links using it by default.

Anyway, to resolve this problem do this:

  1. Go to ~/.local/share/applications.

  2. Backup this directory somewhere safe.

  3. The mimeapps.list file contains the reference to use the offending apps under the *.desktop files there which you can search for the reference to the apps.

  4. Remove these line or their portions from mimeapps.list.

Now you may need to restart the desktop apps or the desktop environment (not sure).

Hope it helps.

Here’s how I found it: after some false leads of either trying to recursively search my home directory for occurrences of /opt/firefox and reading the source code of HexChat, GLib and gtk+ to see where this happens (there were too many levels of indirection there), I ended up doing “strace -f -o hexchat.strace hexchat” and inspecting the strace file for hints.

The Lost Souls of Freenode

I originally wanted to written a more prose-like blog post about the topic of “The Lost Souls of Freenode”, echoing some of my frustrations from trying to help people on Freenode channels, especially #perl and ##programming and I started from keeping a list of bullets and sub-bullets and decided to keep it this way out of being lazy. Maybe it can also be considered the blog equivalent of some wikiHow pages.

After I gave a link to the bullets to someone I met on Freenode, he told me he hasn't found any of what he read here surprising from his experience on IRC and as a tutor and T.A. (= Teacher Assistant) in an American college.

  • “Many Lost Souls” on Freenode's #perl - IM conversation.

  • Quote the conversation about “First rule of #perl channels” (meaning that Freenode’s #perl is our first line of defence).

  • People having problems getting indentation right.

  • People who /msg me after asking.

    • Either they think that's the way to answer.
    • Or they think that I cannot help them because there's another conversation.
    • They're usually not willing or cannot afford to pay.
    • Someone who thought that paying me 50 USD / hour for private help was too high.
  • * People who want us to write their code for them.

  • “Help me with a script I found.”

    • Often badly written.

  • “Help me with using a program / my operating system / etc.”

    • Not even related to coding.

    • “Are you using version control?” “No, what's that?”
    • Automated tests?
    • A debugger?
  • Old versions of perls.
    • Homework/scholastic constraints.

    • “We didn't study it yet”

    • “No external modules / CPAN”

    • “Not allowed to any built-in language data structures, including not arrays.”

      • Mandatory course.

      • Graded 0 once because was programmed on Python-2.7.x and tested on Python-3.3.x (on Windows).

  • One who didn't know what files are nor did file I/O.

    - Ruby

    - private conversation with someone else who didn't know what files are.
