As mentioned previously, I am hacking a bit on a proof-of-concept word processor. Right now, it's hosted on googlecode and called kuatia . ...

I just uploaded version 0.7 of Marave, my fullscreen text editor to http://marave.googlecode.com ...

I have been thinking on what I really really want in a word processor. And then what would it take to create such a thing. ...

Writing an editor is reinventing the wheel. I know that. I tell myself Marave is a fine wheel, with distinct features, and I think that is true, but, if you are reinventing the wheel, there's no need to reinvent the axle and the spoke, too. ...

Version 0.6 of Marave, my peaceful, fullscreen text editor is now available at the usual place: http://marave.googlecode.com ...

I had a small task today in Marave . The goal was: ...

Marave is a text editor. If there's one thing that's true of most text editors, it's this: they lack the exact features you need. ...

This is not interesting for almost noone, but since my google-fu didn't let me find it and it was a bit of a pain to do: ...

Just uploaded Marave 0.5 to the usual place . Marave is a relaxed, fullscreen text editor that tries not to distract you. ...

I just uploaded rst2pdf 0.12.1 to http://rst2pdf.googlecode.com ...

It's my pleasure to announce the release of rst2pdf version 0.12, available at http://code.google.com/p/rst2pdf/downloads/list ...

As usual, a video showing it: ...

Thanks to Nicolás Pace, I got a video of the Pycon Argentina 2009 lightning talks. ...

Here's what fc-match does: ...

In my original post about it I was referring to Bookrest as a stylesheet editor for rst2pdf , because that's what I wanted, a way to test style changes and see what they did. ...

Yes, the program known so far as " my rst2pdf editor/previewer application " is now called Bookrest. ...

I am in the middle of that honeymoon you get starting a new app. Every new feature seems tobe just 50 lines of code away, there is no legacy code (in fact, you are creating that legacy code), and you learn new tricks all the time. ...

First: I really, really need a name for this thing. I am tired of saying " my rst2pdf previewer/editor app " . ...

Since the last release, there have been many changes, improvements and fixes in rst2pdf . ...

So, rst2pdf 0.10 was not ok. The setup.py that worked on 0.9 simply didn't work for the new version. ...

So all the latest releases of uRSSus have a horrible bug: if you had never used it, it would not work at all. ...

Yay! ...

...

...

Since I did some neat coding on it yesterday and today, I decided it was a good moment to release uRSSus 0.2.11 into the wild. ...

Yes, after months of doing nothing, I hve made some changes in uRSSus , my RSS aggregator. ...

Yes, again, two months passed and nothing on the blog. What can I say, my life takes a lot of my time. ...

First a huge announcement: I will not release anything tomorrow. For the first time in 6 weeks, no friday release from me! ...

I spent a few hours today round Code Golf and here's a neat thing I did.I think this is python's shortest possible factorial: ...

Well, what the title says. Get it at the usual places . No, it doesn't require actual LaTeX. Just Matplotlib. ...

...

I announced it on all other places except here: rst2pdf 0.8.1 is out. What's new? ...

Of course I could be misunderstanding this, but it seems they included uRSSus 0.2.10 in a DVD for some reason :-) ...

So, I failed to release uqbar this week. However, I am releasing rst2pdf 0.8, with SVG support! Get its vectorial goodness from http://rst2pdf.googlecode.com ...

I just committed into trunk of rst2pdf a nicely working SVGImage flowable for reportlabs. ...

One of the big limitations of reportlab is that it has no support for vector-based images. You can't insert SVG, EPS or any other vector-based format in your documents. ...

On my ongoing something-released-every-friday rampage, this friday I will release a working version of Uqbar, a Gutenberg project e-texts interface. ...

Right on schedule, everything I promised, plus much simpler/smarter font embedding, and maybe a bag of chips. More at http://rst2pdf.googlecode.com . ...

...

...

Many new features. Custom page layouts! Multiple frames per page! Multiple layouts per document! Cascading stylesheets! Not very buggy! Get it at http://rst2pdf.googlecode.com or via PyPI. ...

How good? Let me tell you... ...

...

I did a release yesterday, and another today of my rst-to-pdf-without-latex tool. What's new? Here's an incomplete list: ...

This mini-sprint is doing wonders for rst2pdf. Now on SVN: pygments-based syntax highlighting. Example here : rst2pdf's code, in a PDF by rst2pdf. ...

Following my new policy of one release every friday, in 6 days you will see a rst2pdf release. But not any release: a great release. ...

Since revision #17_ you can display Page numbers in headers and footers (only!) by using this syntax: ...

This article is inspired by a thread in the PyAr mailing list. Here´s the original question (translated): ...

Because of a thread in the PyAr list about generating reports from Python, I suggested using ReST and my rst2pdf script. ...

A little over a month ago, on July 15th, I opened a Google Code project called uRSSus. Here's the commit . My goal was to try building a desktop application like if I were building a web application, using a ORM, templating, generic views, and other things. ...

Just sent it to Python Argentina: ...

...

After 27 days of development, uRSSus is finally a really usable app. I miss nothing from Akregator, although there are a few unimplemented things. It was broken the alst couple of days, because I was rewriting large chunks of its guts, but the new guts work much better ;-) ...

...

When trying to serialize python data, often the first thing we look at is pickle. Well, sometimes pickle can be very expensive! ...

...

Yes friends, my desktop feed agregator uRSSus has a brand new release. ...

...

Truly a paperbag release. But there's still hope! ...

Version 0.2.9 of uRSSus , my news agregator is out. Many new features including: ...

It was rather easy because I didn't do the hard part (thanks authors of pyrfeed!)and now uRSSus has a simple " import my subscriptions from Google Reader " action. ...

...

I had planned to release a new version today, but there are too many untested features. A list: ...

...

At least three people have tried urssus (including me ;-) and over 80 have downloaded it. The two that told me anything say it's a nice app. ...

...

So, I needed a python script to create tinyurls. Google gets me here where credit is given to this guy . Of course that guy 's solution is a bit broken, check the comments ;-) ...

...

...

...

I did a fair amount of work in urssus today. The highlight? database schema migration. ...

I spent the day bugfixing. Then, when I realized I was fixing stull like " when you delete a feed, the unread count in the parent feed is not updated correctly " and " if you go to Next Unread article and there are none, make the search wrap " I decided this thing must really be working right, since both things failed me in at least one similar program that claims to be production-ready (not akregator! ;-) So I am releasing it as 0.1.0 ...

...

...

...

When I started this project I wrote: ...

So I did work on it a little last night: ...

...

Yes, I am now using uRSSus instead of Akregator. ...

I decided I needed an automatic report of some things on my email every day, and I wanted it to look nice both in plain text and HTML. Here's what I came up with. ...

I am a user of Argus as a monitoring software. Since it's very flexible and easy to extend, I wanted to add MSN alerts, the same way I had added SMS alerts a while ago. It was easier than I thought! ...

Since I got my invitation and am tired of Haloscan not being reachable from home (not their fault, probably), I decided that my first project would be a comment hosting app. ...

I will probably write a comments app to replace my usage of haloscan. ...

There have been a few posts on planet KDE about text-based presentation tools ( 1 , 2 , 3 ) and while their solutions are all probably better than mine, I have to say I did something in the area about a year ago. ...

The eee is small. It has very little storage. So, why should I use dozens of MB on a word processor? Because I get word documents in the mail every once in a while. ...

Can you be a computer consultant and generally a computer guy without ever installing windows? ...

I have managed to create the most bizarre way to write a spreadsheet engine in Python. ...

Because it's probably never going to work, but if it does, I can point out how ugly it was at first ;-) ...

Yup. Figured out column/cell spans in reportlab, found old rst2rst code that regularizes the table row/columns to be all the same number of elements, and voilá, tables work, including examples like this: ...

Really. I already have a functioning slideshow program , a spreadsheet and I could write a word processor in a week (for some values of " word " , " processor " , " write " , " week " and " a " .) ...

I did a little (very little) more work on rst2pdf [1] ...

It works much better than it did last night. ...

This has always been possible, going via LaTeX. ...

This is the real outcome of my PyWeek failure: a neat library. ...

1 - I don't have the time for this kind of deadlines anymore. Not even one all-nighter? I did nothing on Saturday except real work and family reunion? ...

A bit of progress, although not much time to work on it anymore so I will probably not make it. ...

Not a game yet, but the engine is starting to look good. ...

Suddenly I was having a calm day at work, and Rosario is taking care of the baby, so I spent a few hours on the PyWeek project. ...

Well, it seems I am in trouble for PyWeek. ...

In the last few days I have been learning Django in perhaps the hardest way possible: by being hired to work on a site someone else wrote. ...

Allow me to enter trash-talking mode... ...

I have no idea how, but I ran into this in Linuxtoday : KDE Programming Tutorial 0.2 (Dec 22nd 1998, 00:09:36 ) Roberto Alsina announced that he uploaded to ftp.kde.org the version 0.2 of his excellent programming tutorial. It is also available here . Hopefully, this must-have material will be soon included in the kdesdk package and in CVS. ...

I got a mail from a reader telling me that he couldn't download the sources for Notty, the toy app I developed in my Rapid Application development using PyQt and Eric3 ... in realtime! tutorial. ...

Nowadays, the very little time I have for personal projects is spent doing things like fixing little things and adding little features to BartleBlog [1] and thinking how I could use GLE and mako templates to create a cool nerdy tool to create charts. ...

Said Giles Bowkett The Perl community's starting to look more and more like the Lisp community every day. The combination of incredible power, reclusive wizards, and antisocial Slashdotters gives it the vibe of a lava-filled wasteland dotted with towers where strange men with white beards obsess over unspeakable knowledge. I spoke to someone once who compared programming in Lisp to studying Kabbalah, in that it does strange things to your head. Parts of Perl are like that. Still, source filtering's kind of cool. Unnecessary, but cool. ...

You may have noticed no posts about StupidSheet for about a week. ...

...

For my spreadsheet project, I had to redo something I had forgotten about: cell displacement. I did that once when the formula language was python. ...

After hacking for about two hours the cell dependencies yesterday using dicts, I found myself saying " how can I check if the dependency graph is cyclical? " ...

Adding something else to my plate is probably not a very good idea, but what the heck, I can make it sleep another three years if I lose interest. ...

I apologize in advance for any ugly amateurism in this post. It's my first attempt at a domain specific language :-) ...

In 2004 I saw a recipe about how to make a " spreadsheet " in python in 10 lines of code: ...

On 2004 I wrote a spreadsheet in python, which was about a 25KB download (compressed). It was pretty functional !. ...

I just released a wee piece of software, called RA-WebPass which is simply a webpage that you can use to change linux system passwords. ...

Since the very beginning, BartleBlog has been using CherryTemplate for its output formatting needs. I like it, because it's very simple. ...

Took a while to implement, but BartleBlog finally got a functional menu editor: ...

The Python config objects are convenient and simple, but they have a problem: you can only save strings. That means you need to store numbers as strings and remember to use the getint()/getfloat() methods (or coerce by hand!), which is error prone and anti-pythonic. Storing a list is even uglier. ...

... has been all about UI. ...

- Done with the main blog config dialog. ...

It's remarkably easy to turn your QTextBrowser into a limited web browser, at least good enough to show images from the web. ...

I found a couple of hours to hack, and decided to spend them on BartleBlog. ...

...nothing. ...

As a result of my playing with mootools and creating powerpoint-style slideshows on webpages from restructured text, I am pretty much decided about turning this into a standalone, real application. ...

Now, I don't know if this is useful, but I do think it's way neat. Inspired by S5_, rst2s5_, and mootools_ I took an hour (or two) and hacked this neat little slide tool. The goals differ from S5 in that I intend to write a frontend, so that you have a sort of very-poor-man's powerpoint, but also in that the output should be simple to embed in other pages so that I can eventually make this a part of bartleblog. Check it out (click to go to next slide, move mouse to the top of the slideshow for controls): .. raw:: html <div class="sl_presentation"> <script type="text/javascript"> new Asset.css('http://lateral.blogsite.org/static/css/slides.css'); slides=[ 'slide0', 'it-s-nerd-oriented', 'it-does-things-simply', 'it-s-very-easy-to-extend', 'and-it-has-kickass-features' ]; var current=-1; var numPages=5; var topMargin=25; var delay=1500; function slide_out() { if ( current > -1 && current < numPages ) { var eff1=$(slides[current]).effects({ duration: delay, transition: Fx.Transitions.cubicOut }); eff1.start({'top': [500]/*, 'height': [0]*/ } ); } } function slide_in() { if ( current > -1 && current < numPages ) { var eff1=$(slides[current]).effects({ duration: delay, transition: Fx.Transitions.cubicOut }); eff1.start({'top': [topMargin]/*, 'height': [450] */} ); } } function next() { slide_out(); current=current+1; slide_in(); }; function prev() { slide_out(); current=current-1; slide_in(); } function controls_in() { var eff=$('controlBox').effect('top',{ duration: 100 }); eff.start(0); } function controls_out() { var eff=$('controlBox').effect('top',{ duration: 100 }); eff.start(-100); } </script> <div id="controlBox" class="sl_control" onMouseOver="controls_in(); " > <span id="prev" onClick="if (current > 0 ) {prev();}">&lt;&lt;&nbsp;</span> <span id="next" onClick="if (current <numPages-1) { next();}">&nbsp;&gt;&gt;</span> </div> <div class="sl_cover" onMouseOver="controls_out();" onClick="if (current <numPages-1) { next();}"></div> <div id="header" class="sl_header"> </div> <div id="footer" class="sl_footer"> Why use BartleBlog </div> <div class="sl_slide" id="slide0"> <h1>Why use BartleBlog</h1> <h2 id="if-you-are-a-nerd">(If you are a nerd)</h2> <table class="docinfo" frame="void" rules="none"> <col class="docinfo-name" /> <col class="docinfo-content" /> <tbody valign="top"> <tr><th class="docinfo-name">Author:</th> <td>Roberto Alsina &lt;<a class="reference" href="mailto:ralsina&#64;kde.org">ralsina&#64;kde.org</a>&gt;</td></tr> </tbody> </table> </div> <div class="sl_slide" id="it-s-nerd-oriented"> <h1><a id="it-s-nerd-oriented" name="it-s-nerd-oriented">It's nerd-oriented</a></h1> <p>It's trivial to display source code, with proper syntax highlighting.</p> <div class="code-block"><pre><span class="k">from</span> <span class="nn">base64</span> <span class="k">import</span> <span class="o">*</span> <span class="k">def</span> <span class="nf">myFirstFunction</span><span class="p">():</span> <span class="k">print</span> <span class="n">b64decode</span> <span class="p">(</span><span class="s">&#39;YnllIHdvcmxkIQ==&#39;</span><span class="p">)</span> </pre></div> <p>Even for things like shell sessions.

In my previous post, I mentioned how PySPF does something using a regular expression which I couldn't easily reproduce in C. ...

For a few months I have been using an unmanaged virtual private server from Tektonic , and I love it. ...

One of the things people study when they " learn unix " is shell scripting and usage. Because every system has a shell, and if you learn to use it interactively, you are half way there to automating system tasks! ...

I am now almost recovered from the trip to Santa Fe for the Jornada Python and I have reached a few conclussions. ...

Today's entry has no pieces of neat python code, no questions, no critic of anything, no interesting link, no hint of anything I wrote/(would/will)write, no funny piece, no unfunny piece, no nothing. ...

Thinking about CherryTV and ways to turn it into a real application, I thought the worse piece of it was the reliance on v4lctl, and how really you just don't know if it works or not, and how you can't finetune, and whatever, and run into Python-v4l . ...

If you are one of the three persons who actually see this blog on its site instead of reading it through some sort of aggregator, you may have noticed I have a banner. ...

I have posted in the past about runit . ...

A simple (yeah, sure!) solution so you can watch TV on all the computers in your home. CherryTV! ...

In this russian site, you can see how they got my post about the Santa Fe python event. And apparently what impressed them is the thing about the fish and the beer. . ! ...

Bilingual entry here: ...

FaxWeb, a web frontend for mgetty+sendfax is finished. It works. It's probably close to bugfree ;-) ...

In January, I suggested it would be trivial to write a preprocessor that would accept a version of python which delimited blocks with braces instead of indentation. ...

I have an idea that can kill the most frequent complain about python. ...

I just found here the announcement of the first free software I published (at least, that I recall), from may 13, 1996. So, It's going to be 10 years in 5 months! ...

About http://www.pycontest.net ... here's how it's done. ...

There is a python contest at http://www.pycontest.net/ ...

A long time ago, there was no Internet. ...

This is what I understood of Smoke so far. I may be way off, since it is C++ sorcery of a higher level than I'm used to, but I really think I am getting the hang of it (and a bunch of thanks to Richard Dale and Ashley Winters who are the ones that made me understand so far. Any mistakes a re my fault, any good thing is theirs ;-). ...

I just realized I have not learned a whole new real language in almost 5 years. ...

I was trying to do something weird: take one of my PyQt proggies, and compile it into a standalone binary using Jython, koala/qtjava and gjc. ...

A long time ago, I wrote a piece about how I didn't like kcalc. It contained a very lame pyqt script showing a (IMHO) nicer calculator. Strangely, that lead to two very cool implementations of the concept! ...

Nuevamente este año voy a estar en CafeConf . Es una charla de 45 minutos sobre PyQt el 13 de octubre al mediodía. ...

CherryPy is a cool, pythonic, simple, quick, fun way to write web applications. ...

A Little History ...

For a bunch of apps I write, I often want to be able to add a systray icon. ...

Well, reading in planetkde about how nice data aware widgets would be, I have to say this: ...

Ok, not really, since SSH has made my life much simpler than it would be otherwise, but really, it has some usability issues. ...

I am, as always, playing with stuff. And I was faced with a problem I must have solved a dozen times before: Given a list of items with obvious hierarchical names (say, a list of folders), turn it into a reasonable data structure. ...

I have been writing web-based interfaces for applications for about 5 years. Nothing public, nothing very interesting, just tiny front ends for custom tools in clients' installations. ...

Well, I am still experimenting with my concept-distro. ...

I am no fan of source-based distributions. I think that for most practical purposes, a distribution where installing KDE takes over a day (I own a lowly Duron as my fast computer) is useless. ...

Here's the challenge: a nicer version of Qt's data-aware widgets, using PyQt. ...

Trac is cool. Easy to set up, easy to run, low maintenance, and you get: ...

As some may remember, a long time ago I started writing a Bejeweled! lookalike using PyQt. ...

I wrote a little spreadsheet thingie a few days ago. [1] ...

I have been playing with this code and it's been lots of fun. ...

As I mentioned before, I was at the 3rd CafeLUG event on friday and saturday. ...

Since porting HTML display engines from one place to another is all the rage these days, I did a little hacking on one of the oldest forms of the art: ...

Tavia seems to be another KDE web browser. ...

Python code really doesn't look good on planetkde, so follow the link to my page to see it right if you are there ;-) ...

As I blogged earlier I am writing a game (and yes, it's pretty much playable already). ...

From Speno's Pythonic Avocado. ...

Does such a thing exist? There are dozens, but none seems very good. ...

Good news: It seems I have been accepted to teach a PyQt tutorial at akademy . ...

Here is a new realtime PyQt tutorial. For those who have not seen the first one, here's the main idea: ...

It has been way too long without posting a longer item, so... I recicled a script I wrote for a customer, and here it is: ...

I am trying to do something which is, I think, pretty cool, in python. ...

A short tutorial explaining how to create reusable widgets using PyQt. ...

In a whim, I checked out kdebindings/dcoppython from KDE's CVS. ...

There's a problem often used to show the unintuitive nature of probability, which has become very well known. ...

It's better than I remember. Specially because the SF CVS version is newer than all the copies I had on disk (I wonder how that happened). ...

Phil´s support is great. That´s good enough news, but he helped me make images-and-http-in-qtextbrowser work again. ...

Is there a name for that? It's like picking oneself by one's bootstraps. ...

This is a recipe at the Python CookBook showing how to add a new directive to reStructuredText, called code-block, which syntax-highlights the block! ...

Looks like the programming tutorial was well received. About 5000 hits in 12 hours :-) ...

Now, this is not a tutorial in the sense that you gonna learn how to do stuff. ...

Now, I didn't expect this to work at all! ...

Looks like the kind fellows at kde-redhat.sf.net have a working PyKDE, and I got it while I was upgrading. ...

Now, if this appears in the site, bartleblog has advogato support.. ...

Hey, it works :-) ...

Using python, it's trivial to turn any module into a XMLRPC server. So, if you are careful writing your app in a modular way, you can move the backend elsewhere in very little code. ...

So, the link below will disappear in a minute or two. Right now, you can get it via CVS. ...

Let's see if bartleblog can edit this.... yes? ...

I got a few mails asking to see Bartleblog... well, if you have a working PyQt, and a working PyDS (advogato support is totally broken right now), and you have a good backup of your blog, then you may try to get it from here (Use CVS) ...

I wonder if bartlebog is a good name. It sure is better than klog, and I like XIXth century lit references. ...

Implementing proper updating is simple in that sending stuff to PyDS is simple. However, having the GUI do the right thing is tricky: ...

Lacks lots of stuff, but the UI is pretty much done. ...

I always dread the moment when a package has to be shared, and something distributable has to be made. You know, don't forget any files, and such. ...

Ok, klog is just a temporary name, but it's 4AM, and I am not creative. So, what is it? It's a PyQT client to PyDS. ...

Linuxtoday.com and linux.com linked to it. A couple of mistakes pointed out and fixed. Switched to py2html python code while I was at it. ...

In the python listing at the end of the article, I applied py2html so it would get syntax highlighting. ...

Nice post at mechanicalcat.net, about why python makes good programming easier, or at least not harder. ...

The python shelve module is too limiting for the database needs of KRsN, so I'm moving it to SQLite and PySQLite. ...

Sadly, not a really usable version, but I got sidetracked by PyKDE and KFTE first. KRsN really needs just a couple of days loving. So, if you REALLY REALLY want to try it, get >PyQt for Qt 3.1 working, and then head for KRsN's sourceforge page, and get it via CVS ...

Well, just uploaded my hacked KDE 3.1 version of PyKDE to ftp://upload.kde.org/incoming/unstable/KDE3.x so it should propagate to the KDE mirrors soon. It seems to work well, even if it doesn't expose ALL the KDE 3.1 API, and it should be useful as a stopgap until the authors release the real thing. ...

Well, just because I want to use KHTML in KRsN, I got the latest PyKDE. It says it is for KDE up to 3.0.3 ... ...

Well, if you are one of the 6 who actually checked the link in the previous entry, you will know I am writing a news aggregator ;-) ...

Just that. Click in the title for details and a screenshot. ...

Well, I have been wanting to have a weblog for a while, specially since I got a permanent Internet connection at home. ...

Well, 6 months without posting an entry. I must confess I was pretty pissed at some people around here at the time (note to self: maybe putting my real email address here is not such a good idea. Some people are really scary). ...
