gallois' blag

I wish I could! :sigh:

I know, it is silly, but ain’t it cool that when you start typing the window name while on exposé it highlights it and pressing enter bring it to the front?

Ae galera, quem estiver na área, apareça para o curso de LaTeX na semana da computação da UDESC (Joinville), dias 22 e 24 desse mês (Setembro), das 0830 às 1130 (GMT -3).

As vagas já acabaram, mas levando notebook da para acompanhar numa boa. No máximo vão precisar de uma cadeira e um power bus.

Another small bug I found on snow leopard is that when using stickies, if you resize the note and then call exposé it fails to get the right size of the window. It looks like the previous size is kept and the backlight of the window is displayed as so.

Not a problem at all, but a bug, for sure.

Sometimes I miss the old school exposé

Yesterday I was working with my 19″ samsung monitor plugged in my macbook. It works flawlessly, absolutely no problems…. until I put it to sleep, unplug the monitor and wake it up.

What happens is that the windows that were on the secondary display won’t be shown by exposé and it is really a pain to get it working normally after that. I had to hide the window and call it again otherwise it was lost somewhere.

Since I got about five windows that I was still needing to use and exposé was messing up with them I opted for rebooting to save some time.

Hope it gets fixed soon.

I’m going through some problems while using snow leopard. I think they might go away after some updates but anyway, here they are.

After some time, my airport just kept turned off when the computer woke up. It was quite annoying since I almost never turn the mac off. The workaround was installing an app, wireless sleeper, that, besides turning the airport on on waking up, turns it off when sleeping. The second part is rather useless, but hey, now I don’t have to turn it on again every time.

I’ve experienced some HUGE slowdowns with Safari. Usually just restarting it gets it back to normal, but sometimes it is really a pain in the ass. Opening a new tab takes about 5 seconds, something that NEVER happened with Leopard.

The exposé is choppy compared to the Leopard version. The command + 1  and command + 2 are welcome, so as the organized look. Maybe it is just bad luck, but it happens quite often to me. Right now I’m with many windows opened and it is working fine, so I have no idea of what is causing that.

Parallels SUCKS. I haven’t upgraded it yet, but as it is there is no better word to describe it: SHIT! Many times slower than what I was getting with Leopard. Restoring the machine state, using the VM, suspending the machine. Everything is soooooo slower than before that it boring.

There is a small glitch with the dock (I use it hidden) and expose, when you call expose while leaving the mouse cursor over an icon and calling and dismissing it again will make the icon “pop up”… sort of… Calling exposé, hovering the mouse over and then out of the dock, and dismissing it will take the glitch away… but anyway… it happens It doesn’t bother me at all, but it is noticeable and as people at Apple are concerned with those details, they’ll probably fix it.

I also had some problems with a CalDAV that was working previously, but since I rarely used it, I removed it and can’t see the problem anymore

My macbook is running a bit hotter than before, but it may be some dust inside it. I have to check it.

Well… I guess I complained a lot, but I absolutely didn’t dislike Snow Leopard. It is stable, fast (most part of the time), has some great features (most of them are details, but I like the way it is) and works pretty well with most of the software I had.

For a first releas, it is very good and I intend to stick with it. Keep up the good job!

Today I read something that was very pleasant to me. Con Kolivas is developing patches for the linux kernel again. First SD, now we have BFS (Brain Fuck Scheduler) that, according to him, has a very simple design and is also intended for desktops. The patch was developed taking out some fat from CFS (it doesn’t mean it is developer over it), which scales well for heavy loads on multiple CPUs, but that is not the reality for a good part of linux users, mainly the desktop users.

After all the guy went through, I find it pretty cool that he is back. It is clear that he is doing all for fun, the faq speaks by itself.

“Why Brain Fuck?”

…

“Because it’s designed in such a way that mainline would never be interested in adopting it, which is how I like it.”

…

“Because I must be fucked in the head to be working on this again”

…

“Are you looking at getting this into mainline?”

…

“No. They would be crazy to use this scheduler anyway since it won’t scale to their 4096 cpu machine.”

…

“it will compromise the performance where *I* care”

I’m glad he is back

The first successfull boot was on last 25th, so there are probably some bugs. The only known is tracing tasks, which the author asks not to be done until he fixes it.

As always, do it at your own risk and any help is welcome.

Good job -ck!

Hoje li uma notícia que pra mim foi muito agradável. Con Kolivas voltou a desenvolver patches de escalonadores para o kernel do Linux. Depois do SD, temos o BFS, Brain Fuck Scheduler, que de acordo ele tem um design extremamente simples e é também voltado para desktops. O patch foi desenvolvido tirando gorduras do CFS (mas não significa que foi desenvolvido sobre ele), que escala muito bem para grandes cargas em muitas CPUs, o que não é a realidade da maior parte dos usuários linux, principalmente desktop.

Depois de tudo que o cara passou, achei bem legal ele ter voltado a ativa. É nítido que ele faz tudo isso por diversão, seus comentários o faq mostram isso claramente. Alguns trechos são incríveis:

“Por que Brain Fuck?”

…

“Porque foi projetado de uma maneira que o mainline jamais se interessaria por ele, e é assim que eu quero”

“Porque eu devo estar com a cabeça fodida por estar trabalhando nisso de novo.”

…

“Espera ver [esse patch] entrando no mainline?”

…

“Não. Eles seriam loucos de usar esse escalonador já que ele não escala em suas máquinas com 4096 processadores”

…

“porque [fazer isso] comprometeria o desempenho com o qual *eu* me importo”

Fico realmente feliz por ele estar de volta

O primeiro boot com sucesso aconteceu no último dia 25, então provavelmente ainda devem haver alguns problemas. O único conhecido é com o tracing de tarefas, que o autor pede que não seja feito até que ele consiga uma correção.

Como é de costume, o uso é por sua conta e risco e toda ajuda é bem vinda.

Bom trabalho -ck!

I’ve installed Snow Leopard by this morning. It hasn’t been a long time, so it’s hard to tell how everything is going. This post is just for telling what it prompty shows

First things first, the installation

As we could expect, it is really simple. Push the DVD in, double-click the installation icon, click twice on continue and you’re done.

I was upset about the 55 minutes it took for upgrading, from the begining to the reboot. Anyway, after that, I got a pleasant surprise. What people was saying about 5 to 10 GB of disk space freed was far from true to me. I got a whooping 20GB! From 30GB to 50GB. A LOT more than what I expected. I believe it was so because of the huge amount of software that I have installed on my computer, and thus removing the PowerPC stuff could free a lot of space.

After I got it installed I was trying to find broken stuff. So far, the following apps were down: istat menu, mailunreadmenu, istumbler, growl and kismac. Let’s get on it:

ISTAT MENU

Installed the beta 2 over it and it’s ok now.

MAILUNREADMENU

The update didn’t work, so I removed it and reinstalled. Working fine.

ISTUMBLER

No way xD

GROWL

It says it is not working, and indeed the prefpane is broken. Anyway, the notifications are 100%, so… who cares?

KISMAC

Passive mode is ok, active is broken. Using AirPort Extreme

Another app peoplo were complaining about was Cord, for me it was working. Updated and so, no problems at all.

Now, let’s talk about the OS. Exposé is damn nice. I was affraid that cleaning up the chaos that the windows were spreaded over would ruin the fun of it. I really liked the way it was. But I really can’t complain about what has been done. Much better than expected. The tags below the windows are a nice touch (although using the meta key in Leopard had the same effect). A brilliant detail is that the minimized windows also appear in exposé, below the others. It is now easy to call them without running to the dock.

The finder preview is cool, I don’t find it that useful, but it is, to say the least, pretty. A much more appreciated feature is the wireless signal strength that is now shown in the menu bar or when you are trying to find a network. Quicktime X is clean, fast and ran pretty well here. I’m not a big fan of it, but I’ll give it a try.

As I find more stuff I’ll post here.

BTW. command+meta+eject puts your mac to sleep. Maybe I’ll unbind the quicksilver shortcut for calling the screensaver.

Instalei o Snow Leopard hoje de manhã. Ainda tem pouco tempo, então fica difícil de dizer como realmente as coisas estão. Esse post é para dizer o que ele mostra pra gente logo de cara.

Primeira coisa, a instalação.

Como era de se esperar, o processo é extremamente simples. Coloque o DVD, clique duas vezes no ícone de instalar, clique em continuar duas vezes e pronto, a atualização começa.

Assustei com o tempo que levou, muito maior do que o esperado. Fiquei aguardando 55 minutos desde o início até o fim da reinicialização após a instalação. Porém, depois disso, uma surpresa agradável. Aquela estória de liberar 5 a 10 GB de disco rígido não funcionou para mim. Foram 20, isso mesmo, vinte GB liberados. Saltei de 30GB livres para 50GB. MUITO mais do que esperava! Acredito que isso seja pelo fato de que eu tenho muita coisa instalada em disco e a remoção dos binários de PowerPC possa ter tido grande influência nesse ponto.

Depois de instalado fui mexendo procurando os problemas que apareceram. Até agora, os seguintes aplicativos deram problema: istat menu, mailunreadmenu, istumbler, growl e kismac. Vamos à eles:

ISTAT MENU

Instalei por cima dele a versão 2 beta. Funcionou que é uma beleza

MAILUNREADMENU

A atualização que ele fez dizia que ia funcionar no Snow Leopard, não funcionou. O que eu tive que fazer foi removê-lo e reinstalar. Pronto.

ISTUMBLER

Esse não deu mesmo xD

GROWL

Diz que não funciona, que tem atualização à caminho. Mas o único problema que encontrei foi no prefpane dele. As notificações em si estão 100%

KISMAC

Não funcionou o modo ativo, o passivo está tranquilo. Usando AirPort Extreme

Um outro aplicativo que a galera diz que não está rodando é o Cord, eu não tive problemas. Ele se atualizou e eu já fiz algumas conexões, sem nenhum problema.

Falando agora do sistema. O exposé ficou bem melhor, eu tinha medo que a organização do antigo caos da distribuição das janelas ficasse ruim. Sinceramente eu me divertia com os padrões que eram gerados quando o recurso era ativado. Mas ficou melhor do que eu esperava. As tags embaixo das janelas mostrando quais são foram uma boa pedida (embora a tecla meta fizesse isso no leopard). Um detalhe brilhante, na minha opinião, é que agora o exposé pode exibir janelas minimizadas. Elas ficam abaixo das expostas, sem a necessidade de recorrer ao Dock.

O preview de arquivos no finder ficou maneiro. Não achei de extrema utilidade, mas é, no mínimo, bonito. Uma alteração mais sutil, porém mais necessária, foi a inclusão de um indicador do sinal de wireless para as conexões encontradas. Por fim, o quicktime X ficou bonito, rápido, limpo e rodou muito bem, inclusive com legendas. Nunca o usei muito, mas pelo visto agora vou começar.

No mais, sempre que tiver alguma novidade vou colocando aqui.

BTW. Descobri que agora tem um atalho para colocar o computador para dormir (command+meta+eject). Talvez até tire o bind que tinha feito para o quicksilver chamar a proteção de tela.
