Upgrading minor versions QT seems to be a hassle, as each version blocks the previous and because of inter-dependencies, Gentoo can’t understand by itself how to solve them. The solution is to tell it to specifically upgrade all installed modules.

NVidia driver fails to initialize after X restart
This is mainly a note to myself. Sometimes when the X server is restart it complains that nvidia driver couldn’t be initialized and that no screens were found. This may be a result of a version mismatch between X11’s and the kernel’s nvidia module. The solution is to
modprobe -r nvidia
before restarting the X server.
Blocking IP Range using UFW
Uncomplicated Firewall (ufw) is one of the greatest frontends to IPTables I’ve encountered. It is very simple to use and I just wish it was also available for Gentoo. Up until recently everything went smoothly for me and ufw, but we hit some rough waters when I’ve tried to block an IP range.
To block an IP or IP range in ufw you should do
sudo ufw deny from 188.162.67.197/21
An Early Release of the New cssrtl.py-2.0
It has been three years since I’ve released the original version of cssrtl.py (and two since it’s re-release). The old version did a nice job, but experience gained during that time led me to write from scratch a new version. I’ve detailed more than a month ago, the basic principles and ideas that guided me to design a better tool to help adapting CSS files from left-to-right to right-to-left.
The guidelines weren’t just empty words, they were written while working on the Hebrew adaptation to the Fusion theme and in the same time writing a new proof-of-concept version of cssrtl.py. The original intent was to release a more mature version of that code when it will be completed. However, due to the apparent shortage of time in the present and foreseeable future, I can’t see myself complete the project any time soon. So following the “release early” mantra, I’ve decided to release the code as-is. As I said, the code is in working state, but not polished, so it may be of benefit but may contain bugs. If you find any bugs or have any suggestions, I would be glad to hear.

Simple AI Engine for the Oware Game
Sometime ago I worked with a friend on building an Oware game. I was supposed to build the AI engine, and he was supposed to build the user interface to it. Unfortunately, while AI engine interface I designed and a simple alpha-beta pruning engine was implemented, the project was never completed.
RTL and Hebrew Adaptation of the Fusion WordPress Theme
I’ve ported the Fusion theme by digitalnature to RTL, and adapted it to Hebrew.

Simple Histogram Widget for wxWidgets
When working on Open Yahtzee 1.10 (or what ever I’ll call the version after 1.9), I’ve written a simple histogram widget to be part of the new statistics dialog. I should emphasize the simple part, this widget was mean to display a simple histogram without requiring any special bloated ploting libraries. It doesn’t support all the fancy stuff, just plain histogram.
I’ve figured that a simple pie plot would better serve Open Yahtzee’s needs, so unfortunately this code will not be released as part of the program. While the code is not perfect, it’s functional and serves a good example of a custom widget. So I’ve felt pity letting it fall into oblivion in Open Yahtzee’s SVN repository, and I’ve thought it might come handy to someone else (or at least for me) if it will be easily accessible.
Sociable Plugin Doesn’t Play Nice
I’ve been using the Sociable plugin for adding easy “share” links to the bottom of my posts. Up until yesterday I’ve been using the 2.x versions of the plugin, but yesterday I’ve upgraded to 3.4.4. Today I’ve noticed to my surprise that the plugin automatically adds a box to my admin dashboard with “The Latest news from Yoast”, Yoast beeing the plugin’s maintainer, Joost de Valk, blog. The plugin itself doesn’t feature any way to completely disable this “feature”. One has to hide it using the dashboard settings. While this may seems benign, in my opinion its pushing the limit. If I’m interested in getting updates from that blog, I would sign up to its RSS feed. I don’t like getting “free” functionality not advertised in the plugin description.
I must add that as a user of the Sociable plugin, I’m more than satisfied. I probably won’t stop using the plugin just because of this issue, but it still seems to me like improper manners.
Designing a Better a CSS RTL Convertor
About a year and a half ago I’ve released cssrtl.py, a script that translates CSS code to RTL. The script was designed to be fully autonomous, however translating CSS code is a complex task, as not all the information needed to make the translation is available in the CSS files. While cssrtl.py did a very good job on some tasks it lacks on several issues:
- When a design update is released, one cannot use previous translation work.
- When things don’t go smooth, it’s hard to find out why.
- Complex CSS can’t be translated automatically, as it requires understanding of the structure of the corresponding html files and how the CSS will be used by future code.
Over Looking the Simple Solution
Few days ago I’ve decided to start logging my rowing sessions. I disliked the idea of keeping the log on paper, so I’ve looked into a computerized solution. I ruled out Concept2’s online log book, because I wanted something private which wouldn’t require me to register on yet another website (and sometimes internet access at my rowing club is broken). Soon I’ve decided to manage the log using TiddlyWiki, a client-side html+js wiki, which I wrote about in the past. It some nice features:
1. It fits in a single self contained file that is perfect to put on a usb-stick.
2. It has built-in search features.
3. It allows great flexibility in how to log my sessions – no predefined format which I need to struggle to fit my sessions into.
The TiddlyWiki solution seemed great, and I’ve started using it. But as the title says, I merely looked over much simpler, yet as powerful, solution – a simple text file. Porting my rowing log to a simple, old-fashioned, text file provided me all the relevant features of TiddlyWiki, such as search, flexibility and working from usb-stick, while using less space and editable using a basic text-editor (or the powerful vim). Using reStructured Text, I got a nice readable journal that can be later processed into even nicer looking html files.
We all want to believe that we know to match the right tool for a task. But maybe, because we tend to adopt newer technologies and utilities all the time (because for a lot of tasks they do provide better tools), we end up over looking simpler, “old-fashioned”, solutions. If I take a moment now to look around, I can come up with several other places where new stuff is used instead of simpler solutions. Take a look around you, and I’m sure that you will be able to find some too.
