Announcing Weblate

After about week of (not so heavy) development, I can announce availability of Weblate - web based translation tool with tight Git integration.

The project was started because I was not happy with existing solutions (see my blog post) as all of them was missing some features I find useful. I started with quite simple definition:

Minimalistic web based translation with direct commit to git on each translation made. There is no plan in heavy conflict resolution as these should be primarily handled on git side.

Also the project started with defined list of features:

  • Easy web based translation
  • Propagation of translations across sub-projects (for different branches)
  • Tight git integration
  • Usage of Django's admin interface
  • Upload and automatic merging of po files
  • Links to source files for context

Pretty much all of that is completed right now, however there will be definitely some issues which will need fixing.

All important information about the project are available on it's website, the code is hosted on Github. If you are curious how it looks, you can try it out on demo server. You can login there with demo account using demo password or register your own user.

Please give it some testing as I plan to deploy it on http://l10n.cihar.com/ pretty soon.

Ruzyně airport

During weekend, I had great opportunity not only to visit Prague Airport, but also to taste airspotting. As photography is my hobby, this was interesting experience, though I don't think it would be my favorite thing to capture.

Anyway we could see some interesting places - L1011 TriStar KC1 from Royal Air Force, two Boeings 747-400F and Boeing 777-300. The Boeings being the biggest airplanes you can regularly see in Prague.

So lets stop talking and here are few pictures:

Looking for Pootle alternative

For some time, we use Pootle as online translation tool for phpMyAdmin. It is indeed great tool, but somehow we seem to be hitting more and more issues with it and I feel it really won't fit nicely once we will want to support translations on two divergent branches. Also it's code base is not something easy to understand so that I would be able to fix bugs myself without major effort.

So this is when I started to look for alternatives. Unfortunately there is nothing I could find what would work in way I want. I've looked at Transifex, Translatewiki, Crowdin and others whose names I've forgotten and I still haven't found what I'm looking for.

The key feature I want from such system is full integration with git. This means that whatever is changed should be committed to local git branch and merging translations back should be as easy as merging remote branch. I've hacked such thing into Pootle (in quite dirty way), so this is basically workflow we have right now and I'm pretty much happy with that.

Another thing (which seems to be existing in some tools) is support for simultaneous translation of more branches - if same string exists in more branches, it should be translated in all of them. And last but not least, it should support import of po files allowing users offline translation.

Thinking about this I'm starting to thing that it should be pretty easy to implement something what I want using existing pieces of software without major effort. I'll probably start to play with Django, translate-tookit and GitPython to see if I can come up with something working reasonably well in few days...

PS: Anybody working on updated GitPython packages for Debian, looks like I will need them soon :-).

PS 2: The solution for me is Weblate.

phpMyAdmin translations status

With first RC for phpMyAdmin 3.5, we're really close to final release, so let's again look at translations status. Here comes fourth round of translation status update.

Since last update we have three new translations at 100%:

  • Czech
  • English (Great Britain)
  • Estonian
  • French
  • Japanese
  • Russian
  • Slovenian
  • Spanish
  • Swedish
  • Turkish

There are few which are really close to 100% and I hope they will get there soon:

  • Danish
  • Dutch
  • Italian
  • Polish

As you can see, there is still lot of languages missing, this might be your opportunity to contribute to phpMyAdmin.

Yet another project...

Okay, I'm probably really incorrigible. Not long ago, I've publicly complained that I have too many projects to work on and now I just got commit access to another one (after bothering Richard too much with my patches). Anyway I don't expect to contribute much to colorhug client, but somehow it happened that I needed to fix few bits and that lead to finding another bits to fix.

Also I hope I won't have to touch much of other software in color management stack. Playing with Little CMS was nice experience, though I'd still prefer to be user in this area :-).

Secure your phpMyAdmin

phpMyAdmin is quite popular software (to give some numbers let's mention 10000 downloads daily on SourceForge.net or 122685 reports in Debian's popcon) and as such is quite attractive target for various scripted attacks. If you run phpMyAdmin installation somewhere you should really make sure it is enough secured, so that these script kiddies don't get through.

In past month I've looked at what kind of attacks are these guys trying and in all cases these are pretty old vulnerabilities, some of them fixed years ago. So the first thing you should do is to update. It is always good to run latest stable version, but in case you can not for whatever reason, try at least taking the most important fixes and using them.

In ideal world your distribution would do this job for you, but in case it did not, you can for example take patches from Debian, which is pretty good at taking our patches (surprisingly it is not much related to my involvement there). To check which patches they have applied you can use excellent patch-tracker tool, which exposes patches from all released packages.

To give you overview of which issues are mostly being attempted to exploit by script kiddies right now, here is the list:

  • PMASA-2010-3 - yes, more than two years old, but still unpatched in some places
  • PMASA-2011-5 - "only" half year old
  • PMASA-2011-6 - only useful together with wrongly configured PHP

If you have fixed these, you should be pretty safe for now, but follow our security announcements for possible future issues (you can use RSS feed or subscribe to news mailing list, where all security issues are announced as well).

However there are more things you can do to keep you safer:

  • remove setup directory from phpMyAdmin, you will probably not use it after initial setup
  • prevent access to libraries directory from browser, as it is not needed, supplied .htaccess file does this
  • properly choose authentication method - cookie is probably the best choice for shared hosting
  • in case you don't want all MySQL users to be able to access phpMyAdmin, you can use AllowDeny rules to limit them
  • consider hiding phpMyAdmin behind authentication proxy, so that MySQL credenticals are not all users need to login

So these are the basic steps which will help you against possible compromise, I might return to some of these in more details in future posts.

Cleaning up websites, say goodbye to Twitter

Finally I've found some time to do small cleanup on my websites. First of all I've removed links to my Twitter and Identi.ca profiles as they are dead and I don't think I'm going to make them alive any time soon. I never really got into this business and only used it as one interface to feed posts to Facebook (via Identi.ca's app there). Together my mostly read only Facebook usage, there is nothing going on there.

While touching the website code, I also did some cleanup on Wammu website (where Twitter and Identi.ca still stays as announcement media for new versions). Most notable change is that I've reduced usage of external (and in times heavy) javascript and links to social media are now just static HTML, which also nicer fit into website layout. It did indeed remove several options, but I don't think these were worth of the load it introduced.

Prague carnivals

During these days, there are various carnivals in Prague. On Saturday I've visited Malostranský masopust, which is probably not the biggest one, but definitely the one in most attractive location, starting at Prague castle and going down to Kampa.

This was actually my first visit of this carnival and I quite enjoyed it. Bellow you can find some photos taken during the event to catch the atmosphere:

phpMyAdmin translations status

As phpMyAdmin is approaching to 3.5 release, it has come time to share about translations status. Here comes third round of translation status update.

Since last update we have one new translation at 100%, but one has dropped from the list:

  • Czech
  • English (Great Britain)
  • Russian
  • Slovenian
  • Spanish
  • Swedish
  • Turkish

There are few which are really close to 100% and I hope they will get there soon:

  • French
  • Danish
  • Japanese
  • Polish

As you can see, traveling around FOSDEM was really useful for Czech translation, which I've managed to complete during that weekend (+ Monday when I traveled to Nuremberg).

There was great amount of work done on Polish translation, so hopefully it will be on 100% in next report. Also Rouslan is progressing quite well on Italian, but there is still fair amount of work to be done.

Was your language not mentioned? It's now perfect time to contribute to it.
