Preview of xorp v1.8.3 in Debian

I attended DebConf11 and my main objective was to package xorp v1.8.3 for Debian. In the spirit of release early and release often here are the links for a package compiled for Debian v6.0 aka squeeze. The work is not finished and most important was not yet reviewed by a Debian Developer. Reports of success are important.

For downloading:

xorp_1.8.3-1_wip4_bpo60_1_i386.deb

xorp_1.8.3-1_wip4_bpo60_1_amd64.deb

For accessing the sources or using apt-get add the following lines to your /etc/apt/sources.list:

deb http://debian.tagus.ist.utl.pt/debian squeeze/UNRELEASED main contrib
deb-src  http://debian.tagus.ist.utl.pt/debian squeeze/UNRELEASED main contrib

De Lisboa ate Banja Luka para a DebConf11

There is online a description of the travel to Banja Luka from Zagreb, with photos and everything. So this time I will write in Portuguese for the people that prefer Portuguese to English.

A viagem de taxi até ao aeroporto correu sem problemas, não havia trânsito na ponte 25 de Abril. No check-in a fila da esquerda tinha maquinas próprias de check-in e a ajuda de uma funcionária da Lufthansa. Rápidamente fiquei com os 2 bilhetes de ida. Lisboa - Frankfurt e Frankfurt - Zagreb. Por isso despachei-me num estante. O embarque começou atrasado, estranho para uma companhia alemã. :-) A viagem correu sem problemas tirando alguma turbulência na aterragem. Em Frankfurt o céu estava cinzento e a pista molhada.

O desembarque em Frankfurt foi nas portas A do terminal 1. Nos placards o meu voo para Zagreb ainda não tinha porta de embarque, apenas Terminal B. Assim comecei a minha caminhada até às portas de embarque B, que se revelou ser bastante comprida. Demorei perto de 30 minutos a chegar à porta de embarque do meu voo seguinte. Comecei a andar, quando à minha direita vejo um imponente 747 da Lufthansa a vir em direcção à janela. Após uns minutos de espera seguiu o seu caminha pela minha esquerda. Como um elegante elefante na selva de betão de um aeroporto.

Foi uma longa caminhada através do terminal A, até encontrar o túnel de ligação para as portas de embarque B. Finalmente à chegada ao terminal B, o meu voo tinha porta atribuida, diferenta da do bilhete. O embarque começou exactamente à hora marcada. O embarque foi feito para o autocarro que nos levou até ao avião. Rápidamente estava toda gente sentada, mas a hora da partida fomos informados de um ligeiro atraso, para esperar por passageiros de outros voos de ligação.

Na chegada a Zagreb tive alguma dificuldade em perceber como era o controlo alfandegário. Filas para toda a gente ou filas diferentes para europeus e não europeus. Julgo que não queriam destinguir os diferentes tipos de passaportes. No entanto uma cabina dava prioridade a tripulações e outra para passageiros de voos de ligação.

Logo a seguir ao controlo de passporte, fica a sala com a alfandega, a maquina de ATM e á direita a recepção de bagagem. Esta maquina ATM pareceu aceitar quase todos os tipos de cartão de crédito. O meu cartão de debito Maestro funcionou, para levantar dinheiro para os autocarros.

À saída da alfandega escolhi a porta de saida da direita. Esta porta tem logo à esquerda o autocarro para a cidade, especificamente o autocarro de ligação até ao terminal de autocarros. O condutor fala Inglês, aceitou a minha bagagem e paguei o bilhete ao condutor 30kn. Julgo que este autocarro esperou um pouco mais devido ao atraso do avião. Pois partiu por volta das 20h10 em vez das 20h00. O percurso termina exactamente no terminal de autocarros, não há como enganar.

No terminal de autocarros demorei algum tempo a encontrar o sitio para vender bilhetes. Foi preciso contornar o edifício para encontrar as escadas que levam ao 1º andar onde estão as bilheteiras. As pessoas na bilheteira falam Inglês, mas precisei de mostrar o papel com o nome do destino. Pois não dizia Banja Luka com a pronuncia certa, Banhia Luka? No bilhete procurar pelo número "Peron", este indica de onde parte o autocarro, 405 no meu caso. O preço é variavel pois são varias as companhias que fazem a viagem. Pela a viagem das 22h00 paguei 108kn, o preço mais barato. Paguei extra 24kn pelas minhas duas malas. Recebi 2 papeis, estes são importantes, pois provavelmente não nos entregarão as malas se o revisor não puder confirmar o numero da mala com os dos nossos papeis.

O motorista e o revisor não falam Inglês e parecem que não fazem o esforço para perceber outras linguas, para além das linguas locais. Mas não é problema pois o autocarro faz apenas 3 paragens:

  1. fronteira, tenham o passaporte convosco e não na bagagem de porão. Preparam-se para sair do autocarro, mostrar o passaporte à policia por duas vezes e um deles policia recolher o vosso passaporte para verificações mais prolongadas. No fim o revisor irá devolver o vosso passaporte.
  1. descanso, logo a seguir à fronteira o autocarro faz uma paragem. Permite ir ao WC, fumar ou ir ao restaurante. Este não faz referencia de aceitar qualquer forma de pagamento por cartão e não comprei nada para confirmar. Cuidado para não perder o autocarro, pois não me pareceu que o revisor tenha confirmado a presença de toda a gente.
  1. Banja Luka, a chegada parece ser num simples parque estacionamento onde param os autocarros e os taxis. Fica a 3 Km de distância, por isso recomenda-se apanhar um taxi ou o autocarro. O preço médio fica em 10km ou 5 euros. O taxista não falava Inglês e não tinha troco de 50km, que a maquina do hotel me tinha acabado de dar. Acabei a receber 20 euros do troco, o que foi justo.

Penso eu porque passava da meia noite, o empregado fez um check-in rápido e ficou com o meu passporte, que foi devolvido na manhã seguinte.

A Not So Short Review of the Kindle 3G + Wifi

I got my Kindle 3G + Wifi (3rd generation) two days ago. In these two days I have study his capabilities.

My first impression was: "is small, light and thin." Everyone was well impressed with the quality of the screen.

I love how easy is to upload documents to the Kindle. With the 3G I can upload Amazon ebooks everywhere and when I want. They are at distance of 1 click and 15 seconds. No need for pre-upload all my ebooks to the Kindle. For my documents I can use the USB port and the Wifi connection (for free). The Amazon service for converting and upload documents means I can email the documents to my Kindle. This service is very good for doc and pdf documents. Another thing, is very nice that the services for converting Web pages offer to send by email the resulting document.

The Kindle is a good gadget for reading ebooks. The other formats like doc and pdf are very readable after conversion, if they don't depend on formating. The loudspeakers have a good sound and should be good enough for audio books

I have experimented my Kindle on the limits of is capabilities and I am well impressed. The screen is too small for reading PDF documents without conversion. But the screen have good detail (160 dpi) and you can try to read them, if you have good eyes, If not, the zoom and pan is your friend. The 600x800 resolution is too low for reading manga, japanese comics, specially because some of them have very small details.

The experimental web browser works in acceptable way with web sites with little or no graphics, like Linux Week News. The "Article Mode" makes the news sites more readable. It's a pity that the comments are not shown is this mode, at least with LWN. The experimental MP3 Player is very simple, good for background music. Not like a dedicated music player, the sound quality is good but not Hi-Fi.

There is an experimental image viewer that can show images of the most common formats, but sometimes it have problems refreshing the screen with the next image. It's good for showing pictures and if the screen was bigger it would be good enough for reading black and white comics or manga.

My surprise was with the wifi. I didn't check it's limitations and I was surprised because I couldn't connect to the eduroam network. The Kindle wifi don't work if "Wi-Fi network is an enterprise or peer-to-peer network" or "Wi-Fi network is not 802.11b, 802.11g, or 802.11n (in b or g compatibility mode)".

In this two days I found that I like my Kindle, it works as expected if you forget the WiFi issue. I really believe that is easier to read in the Kindle than a real pocket book. The problems I found in reading manga or PDFs are what other people were saying. If the web browser was a little better. This Kindle 3G is a keep, the WiFi problems makes the extra money for the 3G worthwhile for me. My other wish is an updated Kindle DX with a lower price.

Things that I would like to do next:

  • Try audio books
  • Connect the output sound to an aux entry
  • A way for converting a web site to an ebook document.
  • Using latex for generating an ebook document.
  • To make ebook documents from the intranet and other documents in heterogeneous formats.
  • Exists more readable fonts, darker, than what comes with the Kindle?
  • Try the hack for personalizing the screen savers.
  • Try the hack for configuring eduroam network on the Kindle.

Battle Royale

"Could you kill your best friend?" Do you want to see a shocking movie? Do you liked "Natural Borne Killers" or "Kill Bill Vol.1"?

"Battle Royale" is not a movie for the faint of heart. You see young lovers trying to kill each other. You see teenagers killed by accident. Be prepared, if you watched "Natural Borne Killers" and have not recovered yet, don't see it.

Do you want to know your answer to the first question. You want to see how people can kill for stupid reasons and in stupid situations. You mind to see blood spilt all over the place. Go see it. The story is simple but have details. The book and the movie have made a big uproar in Japan. Members of the Japanese Parliament tried to get the novel and the movie banned. But they only succeed in making then more successful.

I finished the book "Battle Royale" some months ago. I have seen in the theater "Natural Borne Killers" and "Se7en". The extreme movies that I have seen. So this movie was waiting in my list of movies "must to see".

3 out of 5 stars, Because not every one can see it.

Nagstatmon help monitor network and servers using nagios

Monitoring a network or a group of servers using nagios have some problems. Receiving alarms by email or have a browser with a open page to the nagios site is an option that don't fit well in the work flow of some people.

Nagstatmon is a program that solves that problem. It opens a small window or icon on a taskbar of your desktop and show how many alarms are active. When an alarm triggers you can see where and what kind of alarm and easily open a connection for managing the equipment in fault.

This program is available in Debian testing (squeeze) but the package is compatible with Debian stable (v5.0, lenny).

The homepage for the software is http://nagstamon.sourceforge.net/
