Pacman, es el poderoso gestor de paquetes que utiliza ArchLinux.. y hoy nevegando por los foros de archlinux.org me encontre con un script para optimizar la base de datos de pacman.

Ya existe un “optimizador” oficial, el script pacman-optimize, pero este script lo supera bastante.

Puedes ver el post oficial aqui.
Y utilizar el script:
#!/bin/bash
#
# pacman-cage

Me encantan los rompecabezas. Cuando era niño tenía muchos de ellos, y pasaba horas con mi familia armándolos. Después crecí, y se olvidó ese pasatiempo.

Hasta que me encontré con este programa, ideal para jugar a los rompecabezas.

Su instalación es muy sencilla. Lo único que tienes que hacer es descargar desde éste enlace el .DEB. Si no tienes Ubuntu, puedes descargar el paquete fuente y compilarlo. El link necesario es éste

Una vez instalado abre una terminal y escribe picpuz. El programa configurará el idioma y te mostrará tu directorio:

PicPuz soporta formatos de imágenes JPEG, PNG, TIFF, entre otros. Busca la imagen que desees convertir en rompecabezas y…

… puedes editar las piezas, para hacerlo más difícil. Cuando lo tengas, listo, ¡desármalo y a jugar!:

Espero que este programa les guste. A mí si.

I don’t usually notice music managers, mostly because I resent applications that “manage” things for me. That goes for music, photos or whatever you like.

On the other hand, I’m constantly on the lookout for applications that run light and fast, and at the same time, are “under the radar,” as some of my American friends sometimes say.

Anything FLTK-based or FOX-based usually qualifies. I regularly tinker with XFE and its subapplications, or Dillo in it’s current (and amazing) state. I can add Goggles Music Manager to that list now. But those toolkits are rather low-key, and the applications that use them can sometimes slip by unnoticed.

Occasionally a thread pops up in the Arch Forums mentioning Goggles, with about the frequency of Consonance. Much like that program, Goggles imports lists of files and keeps a database, then gives you a way of sifting through them to play the tunes you want.

In that sense, Goggles (and Consonance, since I mentioned it) is nothing new. What Goggles (and Consonance, since I mentioned it) offers is that manner of music playback at a speed that’s hard to ignore. And since it relies on the FOX toolkit and only a few other libraries, anything that can run a graphical desktop can probably add a wee bit more and get a very solid, very clean interface for playback.

Goggles has a miniature interface (called the Mini Player, which makes sense ) you can push around the screen. It has an equalizer with presets that might match your musical taste. It will show album covers both in the list and when playing. It has nice big buttons to punch for music control, a slider for seeking and a time display alongside a volume control. In other words, all the basics.

But it will also sink to a system tray icon. It has a sleep timer. It will stream music from the Internet (but I admit I didn’t try that). It will arrange and display music as you prefer, make playlists, sync directory changes and a whole bunch of other fun stuff. If you have to have a music manager and it has to be light, this is the one I would submit for your consideration.

Personally, I find it intriguing, but not particularly attractive. On the one hand I appreciate its exceedingly lightweightedness (is that a word?) but … I can’t help it: I don’t dig music managers. It must be part of my DNA. Just about everyone else I know has to have that three-pane iTunes look before they can press “play;” for me, I find it a turnoff.

But it’s hard to snub it when it’s so light and so comprehensive. If I’m the only person who finds it attractive, and yet unattractive both at the same time, I’ll be satisfied with that.

P.S.: If you want to get started with Goggles, the Arch package is called “musicmanager,” and once it’s installed you can start the application with gmm. It took me a little while to find the thing, and another little while to get it started.

Parecia que en este blog nos encantan los atajos del teclado, y sobre todo los navegadores que funcionan asi (recuerden Conkeror y Vimperator). Ahora le toca a Cream, este es un navegador ligero escrito en C con librerias GTK y Webkit. Este navegador funciona de la misma manera que Vimperator en Firefox, quienes usen este extension o el editor Vim se sentiran familiarizados. Este navegador cumple con su meta de ser ligero, y con una interfaz limpia para navegar.

Para instalarlo en Ubuntu es necesario contar con las sig. librerias:

*Libgtk

*Webkit

Instaladas las dependencias, descargamos el codigo fuente de aqui

y descomprimimos:

tar zxvf cream-1.0-rc5.tar.gz

nos movemos a la carpeta:

cd cream/

Y compilamos:

./configure

make && sudo make install

Si todo sale bien, ya tenemos a cream en nuestro sistema

cream &

Para Arch Linux, se encuentra en los repositorios AUR.

Espero que les sirva en su navegacion .

I’m considering something a little daring — rigging the desktop machine I have ready for departure with a desktop that’s a Windows 2000 lookalike.

Knowing full well that the future owner will more than likely completely erase everything that is on there, I am tempted all the more to simply install Arch Linux and make over the entire machine a la Microsoft and see if it wins any attention that way.

Ordinarily I chastise people for trying to slip Linux under the nose of an unsuspecting Windows user; when the truth is out, it leaves a bad taste in the mouth. And it is generally my philosophy that a person’s first run-in with Linux shouldn’t be deceptive or under duress. No one is served by trying to pretend Linux is Windows.

On the other hand, the recipient knows full well that the machine is only licensed to run Windows 98, and has already mentioned that they plan on wiping the drive before putting on XP (a mistake in my mind, but whatever).

So who will I harm by offering up a sidelong alternative?

Nobody probably, but I’m 99 percent sure the work involved will be ignored. I suppose a better way to introduce Linux would be to dump a full Ubuntu installation on it, add a lightweight desktop like the LXDE package, and call it done. Anything I add above and beyond the Windows 98 installation is already ten times more useful, without going through the hours of tweaking IceWM to behave like Win2K.

And on a machine that needs a Japanese environment, I find the task all the more unappealing. Fonts are … unusual here and there between Japanese and English, and I haven’t really figured out the magic combination. And rendering is slow by comparison, and adding or removing programs is unintuitive (for an absolute newbie) without some sort of frontend for pacman. Scim has to be manhandled by a regular user to behave the “right” way. … The list is long.

And I have so many other things I need to be doing. No sense in going through the work when the final product will be summarily eradicated.

See, now I have successfully talked myself out of it. Another nice side effect of this blog. …

Anniversaries always throw me into a retrospective mood, and since August will mark the third birthday of this blog, I have been thinking a little bit about the machines I’ve worked with since I switched to Linux.

I can’t count the number of computers I’ve worked with over the past three years. I’ve installed (or at least attempted) installations on everything from Pentium machines to dual Xeon Pentium 4 servers to OLPC laptops, all with varying success. There are a few that stand out in my mind and particularly fun or particularly gratifying …

Compaq Presario 1020

This is the machine I wish I had kept. Pristine quality, good screen image, flexible hardware, easy to open and maintain, a chain of industry-standard core components, and enough options to keep your standard laptop geek busy for a while.

I got my hands on this though the IT staff at a previous job, where this had been sitting on a closet shelf for almost a decade, doing nothing. They were more than happy to turn it over to me, and giggled furiously at the idea of actually putting a 120Mhz machine to use. Giggled, that is, until I brought it back to work a week or two later, armed with a very sparse Linux installation running a media player with graphic visualizer, wireless connection and a load of other goodies. They were instantly jealous.

Jealous because early Presarios (and possibly even new ones, I don’t know) were armed with JBL speakers and sound quality was unparallelled. After they saw that it was actually functional, actually usable, they realized they had made a huge mistake in giving it away.

It was a mistake I duplicated not long afterward though. In those days I was inundated with hardware, and one more laptop in museum-quality condition wasn’t worth keeping. I realize now that was the machine I needed to keep on hand for a few more years, but at the time I couldn’t spare the space. Perhaps one day I’ll get my hands on another one of these, and be able to make up for the mistake of selling the first one.

Dell Optiplex GX150

Dell made an entire series of GX machines aimed at businesses and government clients, and for the most part these were rather droll, ordinary desktops with no real spice to them whatsoever. But the GX line was strictly a lemons-to-lemonade phenomenon, as this should show.

With the maximum 512Mb of PC133 memory and 1.4Ghz Pentium III processor, the GX150 was suddenly a high-end desktop with a physical footprint no bigger than an encyclopedia. (There were three sizes, if I recall correctly.) Add a low-profile 64Mb Geforce 440 graphics card, and suddenly you have a machine that can run Neverwinter Nights at 1600×1200, Compiz, any desktop application you like … and look exceptionally good in the process.

The mini-case models used laptop optical drives, which meant you could supplant the standard CDROM with a dual layer DVD if you really had to, or pop in a standard size hard drive too. This was a neat split between the parts seen in standard desktop machines and common Dell laptops.

And Linux couldn’t be happier on it. Ubuntu, Arch and a half-dozen other distros that were current at the time all ran smooth as silk, with no hiccups that I recall. Maybe those are rose-colored glasses that I’m wearing, but I have nothing but fond memories of that machine.

I am tempted to also label this one as a “should’ve kept,” but to be honest, these machines were so prolific and still are so common, that you can easily put together an identical computer now, and end up spending less than US$30 for everything … including the cans of paint. Whereas the Presario was clearly an antique, this one could be mimicked in less than a week, and at minimal cost.

Thinkpad iSeries 1200

I was torn between listing this one and the Inspiron as a number three choice. The Inspiron has been on my desk for well over three years and is generally the house workhorse, but the Thinkpad has been more of a learning experience, and more of a success story — particularly recently.

Part of my endearment to this machine is just that it is in such impeccable shape, but another large part is the fact that I’ve learned to do so much with it, and rely on only a sliver of its resources. Hardwarewise it’s a bottom-feeder, and yet everything that goes into this blog, all my e-mail correspondence, chatting, IMing, personal schedules, desktop wikis, to-do lists, torrent traffic, music streaming … you name it, this machine is where it happens.

I suppose that alone is not enough to rank a machine in a “best-of” list, but there’s more than that. It’s hard to explain, but this Thinkpad, and others I have had or used, have a “solid” feel that is somehow reassuring. I know, for example, that it only has a CDROM in it, and I know that 192Mb is the most memory it will ever have. And that 800×600 screen would be an irritation to anyone else, and everyone looks down on Celerons.

But this thing has a die-hard feel to it. It’s nobody’s dream machine, but Linux on this has been nothing short of liberating. No qualms or eccentricities (unless you count that siliconmotion driver issue, which is no longer an issue really), and function way beyond what Microsoft — and maybe even IBM — ever anticipated.

I use that phrase a lot though, so maybe it has lost some of its punch. Suffice to say that this machine has been more of a surprise and more satisfying than a lot of the others. That’s reason enough.

So there you have it. Three years on, these are the machines that stick in my memory the most. There have been countless others, but these are the hall of fame inductees. For my own part, that is.

I had to laugh when I first saw monsterstack’s signature on the Ubuntu forums.

As an Ubuntu Forums discussion grows longer, the probability of someone mentioning Arch Linux approaches 1.

It’s funny because it’s true: Inevitably, regardless of the topic or issue, be it technical, ethical or otherwise, eventually someone has to raise their hand and offer Arch Linux as a pat response. It would almost be funny to just enter the words “Arch Linux” in response to any thread in the Community Cafe, except that would be something akin to spamming, and the staff would not find it as amusing as everyone else probably would.

It’s funny because it’s true, but it’s true because in one manner of speaking, Ubuntu and Arch are diametrically opposed. Each one offers what the other lacks, and for that reason it’s common to see a problem or an issue circumvented by offering the other as a solution.

I kind of touched on this last year, but did a rotten job, in retrospect, of explaining the phenomenon. Arch Linux draws people away from Ubuntu when they realize Ubuntu is overstuffed and suffers a weight problem.

That alone is a turnoff for some people — the fact that, even in its slimmest configurations, there is a loss of speed and performance that is measurable when held up to something like Arch.

This is not news to anyone who has used Linux in its current incarnations; I’ve been chanting that mantra for years now, and I heartily endorse Arch as an option to anyone who wants to see some measure of perfomance. I can say with 99 percent assurance that, whether or not you use Pentium III-era machines, picking up Arch will offer a huge payout in performance.

But it must also be said that there is a flow to match the ebb. Occasionally — and I admit it’s rare to see — there’s a note on the Arch Linux forums saying something like “I prefer the way Ubuntu handles this.” It’s an odd sight and everyone takes a screenshot to prove it happened, but trust me, it does.

So that performance I mentioned earlier might come at the cost of something else — probably “ease in setup,” if I can say it that way — and that’s usually what sparks those rare forum threads that suggest Ubuntu as an option.

The probability doesn’t really approach 1 though. Or if it does, it’s over a much, much longer time.

P.S.: The threads suggesting Crux as an option to either of those two … well, I might be the only person driving that campaign.

P.P.S.: monsterstack has a blog here, which is fun to peruse. I particularly enjoy the “troll of the week” feature. …

I hold a grudge, I admit it. Months ago, when X started acting up on my central machine, I realized the time and effort spent trying to fix it could be alleviated completely by omitting it altogether.

And as I mentioned then, things have only gotten better. Steering clear of X and anything related has slimmed the system down to nothing without losing a sliver of function, made my system far more reliable, and taught me a thing or two about using still older machines.

But thinking back, my grudge goes deeper than just the failure of the siliconmotion driver (something, to my knowledge, that still doesn’t work), and really extends all the way to November, when all of X turned sour for me. When X shifted to a reliance on hal and dbus, and I had to rely on obscure options (that don’t seem to work anymore, I should add) to avoid using them, I realized the relationship had gone south.

Nowadays I’m hard-pressed to come up with a reason to like X as it travels in the direction it has taken. Consider:

• hal and dbus are heavier than I like. I realize that both are a mere speck in the grand scheme of things, but to me, it’s still more processes than used to be required. I am not so much of a code monkey to fully understand all the reasons why they’re necessary, but I know it has made things harder on me.

  I’ve scrambled a half-dozen installations simply by forgetting to start both hal and dbus before starting X, and without some sort of fallback or preventative check, the only result is that complete lockup. Power down the hard way, file systems go nutty, and the system needs major surgery to get back on its feet. :|

• I don’t know what else to call it, so I’ll just say it: I don’t like the dontzap behavior. I got used to having CTRL+ALT+Backspace, and I’m one of those people who thinks there ought to be an escape route by default, not as an add-on.

  If X were 100 percent foolproof, if it never made a mistake and configured everything correctly every time, I couldn’t complain.

• But it doesn’t, and correcting it when it goes wrong is just as much work as setting it up the old way. In some cases, it’s actually more. As an example, I exchanged e-mails for a few days last month with a person setting up keyboard-switching in IceWM. To hear it explained, the old system required only a brief edit of xorg.conf, but the new arrangement needs much more attention.

  I don’t have the final details so maybe it’s not fair to hold that up to scrutiny, but it’s the way things seem to go for me too. My Inspiron, with an Arch installation in place (and yes, with hal and dbus running ) can’t find the touchpad, or any of the four buttons unless there’s a PS2 mouse connected. It can find the pointer stick — which is important — but if there’s no mouse plugged in, it’s buttonless.

Maybe I’m being hypocritical, since I obviouly still use X on the Inspiron. I’m pleased to say that you can still run a hal-less and dbus-less system with Crux, but I get a sinking feeling every time there’s an update within xorg, because I know at some point that’s going to change.

Or maybe I just complain too much, and do too little, and should take some of my own advice. But instead I take the roundabout solution, and like I mentioned, I omit X altogether, for at least two (and sometimes more) machines.

That’s because short of fully preconfigured systems, like Ubuntu, I see now that X is not nearly as useful (or important) as I thought it was. Or maybe I should say, I see now that there is a lot to learn — and a lot to be gained — by leaving it out.

Esta es la tercera entrega de posts sobre el desarrollo de los diferentes entornos de escritorio para GNU/Linux, anteriormente habíamos hablado de KDE y GNOME, ahora le toca a los entornos “ligeros” XFCE, LXDE y Enlightenment 17, que se han vueltos entornos muy populares para distros que buscan la rapidez.

XFCE 4.6.1 y mas: El proyecto XFCE en este año ha lanzado la versión 4.6 de su entorno de escritorio y su actualización 4.6.1. El proyecto XFCE claramente busca quitarse la imagen se ser un GNOme-light, ya que con esta versión agrego su propio mixer, además de adoptar a Midori (navegador ligero webkit) como parte del proyecto. Entre las cosas que mencionan en el desarrollo es mejoras en el appfinder que le permita reconocer comandos tipo terminal para ejecutar, aparte de soporte para URLs, o microblogging (ver imagen), soporte para sftp para Thunar, además de añadir soporte para Cairo, y añadir extensiones para xfce4-panel y thunar. Este es otro que proyecto que cambiara bastante cuando salgan las librerías GTK 3.0, y que con cada version mejora en funciones y que tiene un desarrollo constante.

LXDE: Este entorno ha adquirido una popularidad entre distribuciones ligeras, con gestor de ventanas openbox, este es un ejemplo que es mas que la suma de sus partes (lxpanel, lxrandr, lxnm, gpicview, pcmanfm). Una de las notas es que posiblemente este pueda convertirse en proyecto auto-mantenido por la comunidad Ubuntu, cosa que aun esta por verse. Otra cosa es el cambio total que tendrá Pcmanfm, ahora basado en una librería en desarrollo libfm, así como basarse en gio/gvfs (quiere decir que podrá abrir lugares como trash:/// o computer:///). Otro sera lxnm (el manejador de redes de LXDE) para convertirlo en una aplicación aparte (algo asi como wicd) sin depender de lxpanel. LXDE siempre me ha parecido un híbrido entre los entornos de escritorio y gestores de ventanas, y una opción para equipos viejos, bueno que no se han desviado de esa opción.

Enlightenment 17: El proyecto de nunca acabar…E17 sera una evolución en lo que conocemos como entornos de escritorio, tanto en lo visual como en el uso. Quizás hace un año el proyecto parecía casi muerto, pero se han puesto “las pilas” actualizando las EVAS y no las que están pensando..sino las librerías que forman parte del proyecto (Einas, Evas, Ecore, Edje, E_Dbus, Efreet). Hay formas de probar el proyecto E17 (por ejemplo Elive), pero esta claro que aun esta verde para un uso diario, pasara un tiempo para que podamos usar una version estable de este entorno.

Que opinan uds.?

I actually have spare time these days, even between projects like tearing apart a desktop machine, to clean and restore it. And since I occasionally pick up a game or two when I want complete distraction, I revisited Warzone 2100 yesterday, after a hiatus that approached the better part of a year.

And I was pleasantly surprised. The crowd that follows that game has been doing some great things with it, including a few small graphical improvements, better static illustrations, and the addition of some single-player game options — which I prefer.

I can now play a flat skirmish against the computer, instead of cycling through the campaign game (which I have finished a half-dozen times, probably). I have never really cared much for multiplayer online games, perhaps with the only exception of Tribes.

So the addition of a skirmish mode makes me quite happy. It’s standard fare, generally speaking — an array of maps, base technology levels and color schemes, all of which a play-to-the-death affair.

And I seem to be on the receiving end of that statement. Which is okay, really. I feel I have a chance against the computer opponent, and if worse comes to worst, I’ll just cheat and prove my superiority that way.

Regardless, it’s nice to see a good strategy game getting proper attention, this long after its original release. Hardware requirements are low, but the payoff is smooth animation and clean graphics, even on a machine as old as mine.

And the home page has one of the best user guides I’ve ever seen dedicated to a single game (I think the wikia site for Neverwinter Nights might be the only better resource, in general terms), plus forums, developers resources like a bugtracker, translation services, AI scripting and so forth.

Strategy games aren’t for everyone, but I admit this one is probably the game I have returned to most often, in my brief Linux history. You try it and see if it fits.

Sempre più incuriosito da questa distro, ho deciso di installarla su una piccola partizione del mio hard disk (tanto Slackware in 35 Gb ci sta largo). Risultato: Arch in 10 Gb sta più largo che Slackware in 35; è una distro veloce e minimalista (l’installazione di base non prevede nemmeno un window manager) ma perfettamente adattabile alle proprie esigenze. Di sicuro non è adatta agli utenti inesperti, visto che non ha nessuno strumento di configurazione automatico.

Caratteristiche generali

Innanzitutto mi scuso per la gaffe che ho scritto nella recensione di Slackware: Arch Linux non è una derivata della Slack, anche se sono simili (soprattutto per il sistema di avvio, entrambe BSD-like).

Arch Linux fu creata da Judd Vinet, che si ispirò alla distribuzione CRUX. La prima versione, la 0.1 è uscita nel 2002, mentre l’ultima versione è la 2009.02 (febbraio 2009).

Come dicevo prima, Arch è talmente minimalista che non prevede nemmeno un window manager di default; differentemente da Slackware, che con un’installazione di default ti fornisce tutti i programmi possibili e immaginabili (KDE, XFCE, window manager a palate, programmi poer l’uffico, 3-4 browser web, ecc…), Arch fornisce il minimo indispensabile per accendere il pc e fare il login. Tutta via installare tutti i programmi di cui si ha bisogno è estremamente semplice (devo ammetterlo, molto più che con slackware) grazie a pacman, un gestore di pacchetti con controllo delle dipendenze (più o meno come apt di Debian, solo molto più veloce). Quindi, se appena installato Arch siete spaventati dalla riga di comando, vi basterà digitare:

pacman -S kde

e in pochi minuti (tempo di scaricare i pacchetti dai repo e installarli) vi ritroverete installato il vostro DE preferito! (Se invece volete installare il mio DE preferito, dovrete digitare pacman -S fluxbox).

Potrete trovare qualche difficoltà in più nella configurazione del sistema: non essendoci, come ho detto prima, strumenti di configurazione automatica (es.: xorgsetup, timeconfig, netconfig, ecc… di Slackware), ogni modifica alla configurazione andrà fatta modificando i file relativi (nel 99% dei casi tale file sarà /etc/rc.conf). Probabilmente, comunque, non ne avrete bisogno: io, oltre alle configurazioni richieste in fase di installazione, ho dovuto solo modificare il file relativo all’italianizzazione della tastiera in X e ~/.xinitrc per specificare il WM/DE da avviare al comando startx.

In conclusione, Arch Linux è una distro adatta a chi vuole avere un sistema minimalista, senza tanti fronzoli e con solamente i programmi di cui ha bisogno. Se vi piace Slackware, ma sentite la mancanza di un package-manager con gestione delle dipendenze (non è il mio caso! slackpkg fa il suo lavoro anche troppo bene) e volete provare qualcosa di leggero, Arch è quello che fa per voi.

Pro e contro

Pro

* Velocissima, sia in fase di boot che ad avvio effettuato (anche se poco più veloce di Slackware).

* Potenzialmente completa: di qualunque cosa abbiate bisogno, non dovrete nulla di più di pacman -S qualunque_cosa_di_cui_abbiate_bisogno; attenzione: per qualche strano motivo non funzionano i comandi pacman -S pace_nel_mondo o pacman -S capire_le_donne (in particolare quest’ultimo dà un segmentation fault e manda in crash il sistema)

* Buonissimo supporto anche in italiano, molte guide utili reperibili online (ArchWiki).

* Per la sua leggerezza è adatta anche a computer dell’anteguerra.

Contro

* Inadatta agli utenti inesperti.

* Oltre al Wiki ufficiale, la documentazione è abbastanza scarsa: se non capite le guide di ArchWiki siete fregati!

Alcuni link utili

* Pagina di Wikipedia su Arch Linux (per informazioni più precise)

Am Wochenende habe ich mich endlich mal an ArchLinux gewagt. Arch ist eine Linux-Distribution, die sich eher an erfahrenen User wendet – damit habe ich jetzt quasi offiziell “Geek-Status”, juhu!

Die Installation ist rein textbasiert, rein offiziell wird das gesamte System auf dem Terminal und in Textdateien konfiguriert. Klingt kompliziert, ist es aber nicht. Nach der Installation ging es erstmal an die WLAN-Einrichtung – na toll, in der /etc/rc.conf eintragen half nix. Also mit

# ifconfig wlan0 up

# iwconfig wlan0 essid <meineessid> key <mykey>

# dhcpcd

von Hand ans Netz – zum Glück nur WEP, mit WPA wäre das etwas zäher geworden.

Dann erstmal mit pacman ein Systemupdate eingespielt – natürlich ohne vorher die Mirrorlist zu bearbeiten. Dummerweise ist der offizielle Arch-Server etwas langsam…

GNOME, Xorg, OSS installieren, Wicd, damit mein WLAN auch automatisch ans Netz geht… Nervig, aber nicht allzu schwierig.

Jetzt läuft alles. Die Paketverwaltung mit pacman ist genial, Shaman als grafisches Frontend ist top. Die Möglichkeit, mein System nach Ende eines Updates herunterzufahren, habe ich mir schon lange gewünscht. Das RollingRelease-Konzept ist das Beste seit geschnittenem Brot – heute geupdated und schon ist vlc 1.0 auf der Festplatte. Einfach Wahnsinn. Schade, dass die Einstiegshürde so hoch ist.

Ich hätte ja auch Chakra benutzen können – aber leider bin ich eher der GNOME-Junky. Ein GNOME-System auf Arch-Basis mit leichter Installation und LiveCD fehlt leider noch. Wer weiß, vielleicht probier ich mal, da selbst was zu machen…

Erstmal freue ich mich jetzt aber an meinem topstabilen, schnellen und schicken System. Es hat sich gelohnt.

Shutter je screenshot program. Za razliku od drugih programa ove vrste Shutter se odlikuje jednim delom dodadtnih opcija koje slicni programi nemaju. Ovako napravljen program odstupa od Unix filozofije o pravljenju programa koji radi jednu stvar i radi je dobro. Kod Shuttera vazi da on radi vise stvari i radi ih dobro.

Ja sam testirao verziju 0.70.2.  Graficki user interfejs je jednostavan i prilicno lak za koriscenje. Shutter radi sa tabovima. Svaki nacinjeni screenshot otvorice se u novom tabu.
Pod tabom Session nalaze se thumbnejlovi svih snimljenih screenshotova za vreme rada.
Meni Selection omogucava promenu velicine zumiranog polja prilikom uzimanja screenshota dela ekrana,  sto je zgodno ukoliko ivica fotografije mora da bude na tacno odredjenom mestu.

Pritiskom na Full screen hvata se ceo desktop i sve na njemu. Podmeni ove opcije omogucava hvatanje virtuelnih desktopova ukoliko ih ima.
Window opcija je vrlo napredna i omogucava snimanje screenshotova svakog od prozora koji su otvoreni u aktivnom workspace-u. Tu se podrazumeva conky kao poseban prozor i paneli. Nije potrebno raditi snimanje dela ekrana da bi se snimio recimo conky.
Dodatak na sve ovo je mogucnost manipulacije screenshotovima iz samog programa.
Ispod menija Screenshot krije se opcija Edit koja otvara uhvaceni screenshot u novom prozoru sa alatom za jednostavno editovanje. U ovoj verziji programa je moguce dodati tekst, linije slobodnom rukom ili prave linije, oblike kao krug i pravougaonik. Sve dodato se tretira kao objekat koji je uvek moguce obeleziti i obrisati ako nismo zadovoljni promenom.
Tu se nalazi i alatka Censor koja zapravo brise deo slike koji ne zelimo da se vidi. Naravno i promenu nacinjenu Censor opcijom je moguce obrisati Gumicom i sliku vratiti u predjasnje stanje.
Jos jedna od prednosti Shuttera je jedan broj ugradjenih plugina za manipulaciju fotografijom. Izmedju ostalog tu je opcija prebacivanja slike u Pdf, greyscale, zamena svakog pixela komplementarnom bojom , podesavanjem ivica kao i promena velicine slike.
Za kraj, program ima opciju Upload/export koja omogucava direktan upload na nekoliko web strana. Izmedju ostalih tu je i Iimageshack.us. Shutter koristi i ftp za upload kao sto je moguce sliku prebaciti u neki drugi direktorijum na lokalnoj masini.

Shutter moze da sacuva screenshot u .png, .jpg i .bmp formatu. Shutter ostaje aktivan i uvek pri ruci u notification delu panela i odatle se mora ugasiti na Quit.

Since I’m on the subject, I should mention that I prefer to use the precompiled binary for Linux over installing Firefox directly in either Crux or Arch. I don’t have any great insight as to why that’s preferable, except to say that I can still run a Crux system without hal and dbus, if I rely on a precompiled Firefox. (Running X in Crux does not require that I install those two.)

Or at least I could, until Firefox 3.5, which won’t run until dbus-glib is in place. The binary file was complaining that it couldn’t find a specific library, and I managed to track it back to dbus-glib. And of course, with that in place, all was fine.

Not as independent as I liked, but it works. I can’t say for sure that 3.5 is any better than 3.0.x for me, but I see no harm in keeping the browser up to date.

Un martes mas, y empezamos con esta solucion de lectura de feeds. Canto es un lector de feeds Atom/RSS para la consola cuya fin es ser rapido, conciso y colorido. Este programa presenta una interfaz sin menus, se maneja todo a traves del teclado, ademas de poseer capacidades de expansion, gracias aque esta escrito en Python. Entre sus caracteristicas se encuentra:

-Soporte Atom/RSS/RDF

-Soporte Unicode (si lees sitios como digamos japones o caracteres japoneses los podras ver)

-Soporte para OPML

-Integracion con navegadores graficos y en modo texto.

-Poder seguir actualizandose desde segundo plano en modo daemon.

-Acomodar los feeds en grupos o en tags

Para instalar este programa en Debian o derivados (Ubuntu Jaunty en adelante)

sudo aptitude install canto

Para Arch:

Se encuentra en los repositorios AUR

Espero que les sirva

NOTA: En rm -rf han publicado otro lector de RSS por consola, chequenlo tambien se ve bueno,

VLC è alla versione 1.0.0!!! Dopo sei anni di fidanzamento (che ho tradito qualche volta con kaffeine sotto kde 3.x.y) questo lodevolissimo software, che però uso solo per guardare qualsiasi cosa senza problemi, è arrivato alla versione fatidica versione di 1.0.0. Forse non vuol dire un cazzo ma quanti ricordi mi fa venire in mente, quanti film e porno che ho visto grazie a questo programma. Quante anteprime di file non ancora conclusi, ISO da masterizzare…

PS ho finalmente disinstallato k3b che mi accompagna fin dagli albori della mia esperienza con distro GNU/Linux. No ragazzi la versione alpha che si trova nei repo di Arch Linux è  troppo acerba (ma va? è un’alpha!). Ho così installato al suo posto sound-juicer, che si porta dietro anche brasero ma devo ancora provarlo, per convertire dai cd audio (in flac sul pc, non ho un lettore mp3 o similari) e xfburn per masterizzare. Dato che uso XFCE ho qualcosa che si integra anche meglio con il resto.

Ho anche notato che i programmi per KDE hanno maree di robe in più rispetto ai corrispettivi GNOME e XFCE, forse è solo un caso e non so se sia un bene o un male.

K3B je jedan od programa koji je uvek bio must to have u bilo kojoj varijanti linuxa koju sam imao instaliranu na kompjuteru. Na zalost, doslo je vreme da se rastanemo. Ne zato sto sam pronasao nesto bolje. Za Gnomebaker koji ce zameniti K3b ne mogu reci da je bolji. Koliko sam imao prilike da ga isprobam Gnomebaker radi podjednako dobro ono sto je i K3b radio – rezanje diskova i .iso fajlova.

Problem sa K3b je u KDE 4 okruzenju koji pod mojim Gnome okruzenjem izgleda i radi ocajno. Najvise me nervira sto kada hocu da kliknem na nesto u K3b nema nikakve reakcije vec moram da kliknem par milimetara ulevo od polja koje izdaje neku komandu. Na mom monitoru to izgleda kao da klikcem u prazan prostor, sto se ne moze tolerisati.

Pored K3b promenio sam jos jedan program iz KDE okruzenja koji je takodje bio must to oduvek. Rec je o Krename. Ovaj put nije problem bio u vizuelnom odudaranju Krename vec u mnogo vecoj funkcionalnosti Pyrenamer koji preuzima mesto glavne aplikacije za masovno preimenovanje fajlova na mom kompjuteru. Njegova najveca prednost je sto koristi paterne prilikom preimenovanja te je tako moguce promeniti redosled reci i brojeva u imenu jednog fajla. Kako to izgleda moze se videti ovde. Pored toga Pyrenamer radi brze od Krename jer ne mora da se prakticno restartuje svaki put kada zavrsi sa preimenovanjem jednog seta fajlova. Na kraju. Pyrenamer moze da radi sa meta podacima fotografija i audio fajlova i da te podatke koristi prilikom preimenovanja. Ukoliko u renamed image pattern ubacite polje {imagedate} Pyrenamer ce procitati meta fajl kada je snimljena fotografija i ubaciti datum u ime fajla na mestu na kome zelite. Preporucujem uvek koriscenje Preview opcije pre nego sto se promene imena fajlova.

Za kraj da pomenem jos jedan mali ali koristan program. Gonvert je program za konverziju mernih jedninica.  Pored 50 razlicitih mernih polja cije jedinice konvertuje ovaj program je poseban jer radi i konverzije nekih mernih jedinica koje su postojale ranije u istoriji, a danas se vise ne koriste. Recimo moze se preracunati koliko jedan jevreski talent ima grckih drahmi, obolosa i minaha. Rec je naravno o masi,  ne o parama.

Well, everything was going fine with the computers here at fullmetalHQ until suddenly the laptop wasn’t able to connect to the wireless signal from the router both computers use. I was convinced something was fucked up with the laptop or maybe the router. My wife, on the other hand was sure it had something to do with the desktop, specifically Slackware.

A big arguement ensued because I was oh so certain that it was ridiculous to think that the operating system on the desktop could have anything to do with it, and she was sure that was the case because she connected everywhere else just fine with the laptop.

Well, as with all of our arguements, my wife won out and we reached a compromise. I’d install something else and see if the problem persisted. Well, I guess it was a compromise. So, since I had an Ubuntu 9.04 iso laying around, I burned an install disk and slapped it in the desktop.

And sure enough, and I don’t have the slightest idea why, but it worked. No more connection problems.

Trouble is, I don’t like Ubuntu that much. I mean, I installed it with an open mind and was willing to give it yet another chance…but I just don’t particularly care for it too much. I mean, it’s not terrible or anything. But I’ve already decided to load Arch Linux and  see if that will carry me over until Slackware 13 is released and I can get back my slack. Cause it’s just crazy-I had Slackware running on this desktop for over two months and there were zero problems, then I reinstalled it and shit started happening. So I don’t know if my install media went stale or what, but I figure I’ll try again when the next version comes out

But it’s funny, and at the same time one of the great things about Linux-there’s always another distribution you can run if you’re too lazy to fix the problem with the one you’re using. I mean, yeah, I could have figured out the problem and fixed it eventually I’m sure-but my wife wanted it addressed and fixed immediately if not sooner, and honestly though I think Slackware is the greatest thing since peanut butter I just didn’t really want to deal with figuring all types of shit out at the time.

So, now the Arch “cheater” live cd iso is about half downloaded and in a little while I’ll be able to find out for myself what all the hubub is about.

Buscando un cliente de correo, me encontre con esta aplicación muy completa. Es Spicebird, un programa basado en el codigo de Mozilla Thunderbird (la version 3.0), además de otros proyectos como Lightning y Telepathy. Las características sobresalientes son soporte para los applets de Google (los de iGoogle),  también para servicios de google (Gmail, sincronizacion con Google calendar, IM con Gtalk), calendario y para anotar tareas integrado, soporte para pestañas, claro esta las características de thunderbird (correo, noticias, addons de Thunderbird).

La aplicación es multiplataforma, ademas que se encuentra en múltiples lenguajes. Para instalar en sistemas GNU/Linux:

Descargamos el paquete del idioma que queramos (en este caso sera ES-AR):

wget http://files.spicebird.org/pub/spicebird.org/spicebird/releases/0.7.1/linux-i686/es-AR/spicebird-beta-0.7.1.es-AR.linux-i686.tar.bz2

Descomprimos el paquete:

tar jxvf spicebird-beta-0.7.1.es-AR.linux-i686.tar.bz2

Seguido:

cd spicebird-beta/ && ./spicebird

Y ya lo podemos ejecutar en nuestro sistema.

Espero que les sirva

Setelah 5 bulan lebih berkelana mencari dan mencoba – coba distro linux yang lain, mulai dari debian 5.0 lenny, kemudian berpaling ke dekapan openSuSe 11.1, dan akhirnya untuk sementara waktu tertambat pada ArchLinux yang ringan, dan sistem rolling releasenya, sembari melirik-lirik Fedora 11 Leonidas (Sampe bela-belain download ISO DVD nya lho…walaupun belum sempet tak install, baru nyicipin yang live CD doank…hehehe…).

Akhirnya karena merasa bosen harus mengkonfigurasi manual paket – paket aplikasi yang diinstall di Arch Linux (walaupun menantang dan menyenangkan), dan mesti download dari internet paket – paket aplikasinya (gak kuat euy, cepet abis kuota im2 broomku…), disamping itu juga karena ada proyek yang harus secepatnya diselesaikan, maka saya memutuskan untuk balik lagi ke ubuntu, soalnya udah ada repository lokalnya di kampus, jadinya gak perlu download n connect ke internet buat nginstallnya…hehe…^^

Tapi tenang aja, Arch Linux dan yang lainnya gak serta merta ditinggalkan kok, Arch Linux ku masih tetep terpasang di harddisk laptop saya, berdampingan dengan ubuntu ku….

Sebenernya distro apa aja bisa n layak buat dipakai kok, saya balik lagi ke ubuntu hanya karena keterbatasan sumber daya (kuota internet) yang nggak memadai, kita bisa tetep produktif menggunakan distro apapun…

KEEP CODING N OPEN-SOURCE…

Abrimos una nueva serie de posts semanales, asi como los de los fondos de pantallas, los martes hablaremos de programas sin interfaz grafica, y que funcionen bajo la consola, y vaya que hay una buena cantidad de ellos.

El programa que empieza esto es Moc (Music on Console), es un reproductor de audio de consola para los sistemas *nix diseñado para su facilidad de uso. Se puede elegir entre directorios o archivos para la reproducción de audio, búsqueda entre los archivos, formar listas de música y exportarlas en .m3u, inclusive tiene soporte para streaming de audio (Shoutcast e Icecast). Los archivos que lee este programa son mp3, ogg vorbis, FLAC, wave, Aiff, y mas (para archivos wav necesita un plugin). Ademas de otras características como cambio de color, soporte para JACK, Alsa y Oss para escuchar los archivos.

Para instalarlo en Debian o derivados:

sudo apt-get install moc

En Arch Linux:

pacman -Sy moc

Espero que les sirva.

Sayounara

NOTA: El binario de moc es mocp (segun el desarrollador para evitar problemas con otros programas) asi que para usarlo usariamos (un ejemplo, pueden la terminal de su agrado)

xterm -e mocp -I /home/usuario/Música

Hoy leyendo esta pequeña comparaciòn entre Arch y Ubuntu,me he hecho un par de preguntas ràpidas:

• Puede Arch ser mejor que Ubuntu?
• Existe verdaderamente gran tendencia de que los usuarios de Ubuntu migren a Arch?
• Prefiero continuar con el circo de los 6 meses o atarme a los rolling release?

Para no quedarme con dudas,lo instalarè (otra vez) y lo probarè (esta vez) mas a fondo.Pero primero quisiera escuchar un par de opiniones de uds (lectores).

Mi opinion (breve y poco profunda) :

• Arch no està destinado para novatos ni para maquinas viejas.
• Ubuntu ès fàcil de usar y con muchas caracteristicas out-of-the-box.

Corto resumen: Dos grandes distribuciones con diferentes propósitos!.

Tu opinion:

• Porque Arch y no Ubuntu?
• Porque Ubuntu y no Arch?
• Porque las dos?
• Porque ninguna de las dos?

Gracias por tu opinion!.

En post anterior, mi compañero hablo sobre una extensión que permitia manejar a firefox como si fuera Vim. Ahora les traigo un navegador completo que funciona solo con atajos del teclado, como si fuera el editor Emacs.

Conkeror es una navegador basado en Mozilla Firefox , con la finalidad de ser manejado a traveso de atajos del teclado, inspirado en aplicaciones como Emacs y Vim. Al ser basado en Firefox, también le funcionan las extensiones de este (aunque no todas, checar esta pagina). Al principio solo veras una ventana con el manual para usarlo, sin toolbars, una interfaz limpia.

En sistemas Debian o derivados el programa se encuentra en los repositorios:

sudo apt-get install conkeror

Para Arch Linux:

pacman -Sy conkeror-git

Para otros distribuciones pueden seguir estas instrucciones.

Un navegador, que sirve para los que prefieren manejarlo todo con el teclado o también para pantallas pequeñas.

Espero que les sirva =)

Diawali dari rasa ingin tahu n nyoba sesuatu yang baru (Distro linux yang baru),  jadinya saya mutusin untuk nyoba Arch Linux, awalnya sih sempet ragu – ragu juga alnya, dari beberapa referensi di internet n review – review nya, Arch linux tu bisa dikatakan kayak Linux From Scratch, jadi kita secara penuh meng-kustom arch linux kita (semuanya) mulai dari konfigurasi awal sampai nginstall Desktop Environmentnya… (kebayang gak tuh ribetnya??)… tapi entah kenapa saya ingin mencobanya ( yaah namanya tantangan mungkin).., disamping itu juga karena tergiur karena banyak yang bilang arch linux tu bagus, ringan, n dukungan komunitasnya yang sangat aktif, disamping itu juga karena konfigurasi manual (yang katanya) gampang… jadinya makin tergiur deh… Dan yang paling penting tu karena Arch linux menyediakan software – software terbaru karena ia menganut sistem rolling release…

oke, langsung aja saya download iso CD nya yang di-mirror oleh cbn.net.id di http://archlinux.cbn.net.id/iso/, CD installernya berupa network install CD jadi nya cuman base system (sistem dasar) nya aja yang diinstall, untuk yang lain yaa mesti konek ke internet buat nginstallnya… (untungnya waktu itu ada acara nginep di kampus, jadinya gak perlu repot n nunggu lama nginstallnya — internet gratis euy)..

saya rasa sih proses instalasinya gak terlalu susah, seperti kebanyakan cara nginstall linux yang lain, tahap yang paling susah mungkin tahap pemartisiannya aja (itupun gak susah – susah banget), kalo kita ngikutin arch install guide nya semua langkah – langkah akan lancar – lancar aja…

mungkin baru bisa segitu dulu review nya, lagi sibuk nih, banyak kerjaan — biasalah mahasiswa…
