I have feedback about that activity. A kid was experimenting with batteries and light bulbs - they wouldn't turn on, though his wiring was correct.

After thinking about it and tinkering, it turned out there was a missing dependency - `gnucap`, simulation does not work without it. I didn't know it at the time and it was difficult to figure that out because we were in a remote village with sporadic 3G coverage and all those children were buzzing around with excitement (-:

Perhaps it is better to install it along with GCompris (the child-friendly approach) or turn it off (better, but inconsistent across computers) or show an error message (not child friendly at all).

Yes, that photo caught me while I was battling the problem (-:

I've used GCompris (among other tools) last year in a summer camp for children from socially vulnerable families. It was a project powered by volunteers and donations.

The kids enjoyed it very much, due to the variety of activities available - everyone found something to tinker with. If you're interested, have a look at the photos:,

Children liked TuxType and Scratch too, but GCompris ranked #1, especially among the younger ones.

Some youngsters in Moldova had a great summer; and who knows - maybe a few of them will build careers related to computers. And that could be your fault (-:

p.s. I am glad it runs on Android now, I've already recommended it to a parent.

Comment: MyPaint and a tablet with a stylus (Score 1) 96

I use MyPaint with my Lenovo X201 tablet, it supports touch and stylus input. The machine is connected to a regular projector and my students and I are very satisfied with this.

Here is an example of a discussion about hash functions in Python; it is a screencast where you can see me doing stuff in the terminal as well as sketching explanations on a blank canvas.

MyPaint is cross platform, it is designed for artists and painters, but I am happy with it as a teacher. I used to rely on OneNote in the past, but I've moved away from Windows quite a few years ago and never looked back.

In one of Richard Stallman's lectures, someone asked him why progress on Hurd is slow. The response was that this is not a pressing matter anymore, as there are other free kernels out there that are mature.

In other words, there are other problems society needs to focus on, so don't hold your breath for GNU Hurd.

According to the spec, the SIM card has several files that contain information about the networks the phone is allowed or disallowed to connect to. These files are EF PLMN and EF FPLMN, they can be edited if you have PIN1. They're present in both, 2G SIM and 3G USIM cards. For more details, see section 10.2.16 EF FPLMN (Forbidden PLMNs) of the corresponding ETSI standard.

This article on PLMN management describes how they can be updated.

Even though this problem has been resolved a long time ago, in my practice I have not encountered a phone that would offer an interface for editing these settings. So you need to do this with a smart card reader and software that knows which APDU commands to send to the card to make the necessary changes.

> Romanians were actually fighting along with Nazis
It should be pointed out that Romania was originally a neutral state. The country was forced to enter the war after the Entente failed to keep its promise.
Romania joined the war on the side of the Axis because at that time the Soviet army occupied the Eastern part of the country (the region known as `Basarabia`) and had no plans of leaving.

So your statement is true, but I think that another reasonable person would've done the same, had they been in the shoes of the Romanian government at the time.

I'm playing Wordfeud (an online game of Scrabble), I like it because of its pace - I have 72h to complete a move, so I can take my time. The game allows me to play with multiple opponents simultaneously; I've made some good friends and we keep playing for several years now. This game brings people together, if you let it :-)

If anyone could recommend a similar, turn-based, online multiplayer game for Android - I'd greatly appreciate it.

Is it common for people sleeping in tents in such weather to be practically naked, or wearing nothing more than underwear?

Isn't it more reasonable to sleep dressed in pants and sweatshirts, etc. If so, then it means that they got undressed before escaping the tent - that wouldn't make sense.

At this point I'm not sure if you're fooling around or are just misinformed, I will assume the latter.

Romanian is a language, and Cyrillic is a form of writing. You can write Romanian using a Cyrillic alphabet if you really want to, but that's not how Romanians themselves do it.

If you read the first paragraph of Wikipedias's articles on {Rroma, Romanian, Cyrillic} - you'll figure it out.
