Cómo instalar el Google Chrome desde Cuba

, , ,

Update: Encontré unas instrucciones (gracias a un [ULR=http://my.opera.com/gnapse/blog/show.dml/2531579#comment6018669]comentario en mi post anterior) para instalar Chrome en Linux. Lo otro interesante que saqué de estas instrucciones es que ahí dan un link directo al instalador chrome_installer.exe de 7 megas. Así que pueden usar Tor para bajarlo directamente, o darles a un amigo en el extranjero el URL para que lo bajen y se los manden por email.

Algo inusual en este blog, un post en español. Pero es que me decidí a escribir un how-to de cómo descargar e instalar el Google Chrome desde Cuba, y como lógicamente los que necesiten esta guía serán Cubanos en Cuba, no tiene sentido ir en inglés.

Una nota antes de comenzar: El instalador del chrome como tal, de alrededor de 7 mega-bytes, yo lo tengo en mi poder, y si pudiera hacérselo llegar a la gente, o que se pudiera poner en algún sitio en Cuba, en Infomed digamos, desde donde se pudiera bajar, sería buenísimo, pues así no habría necesidad de seguir estas instrucciones, que para alguien no muy ducho en las computadoras pudiera resultar algo complicado. Si alguien tiene idea de qué se puede hacer en este sentido, por favor escríbanme a g_n_a_p_s_e [arroba] g-m-a-i-l [punto] c-o-m
(espero que todos entiendan lo que hay que quitar de aquí para conformar mi dirección de correo)

Y una notica antes de comenzar, es muy importante leer este post completo antes de proceder a seguir las instrucciones. En particular deben leer los últimos párrafos de este post, sobre todo las partes resaltadas en MAYUSCULAS y en negritas.

El problema


El problema fundamental de instalar el Chrome desde Cuba es que el download inicial que nos ofrece Google desde su sitio no es el instalador, sino un pequeño programita (~485k) que lo que hace es bajar de Internet el instalador real del Google Chrome, el fichero de alrededor de 7 megas que mencioné más arriba.

Así que aunque logremos burlar este primer control (creanme, es muy fácil burlarlo, digamos pidiéndole a algún amigo afuera que lo baje y nos lo mande por email, y quién no tiene amigos cubanos en el extranjero?) una vez que tenemos el ficherito en nuestro poder cuando lo ejecuten no tardará en darles un error, algo como que el programa está "unavailable" o algo así (lamentablemente no tengo screenshot). En otras palabras, este programita tambien chequea que estamos en Cuba, lugar maldito, y por ende no nos deja bendecirnos con el navegador cromado (me cago en ende).

La solución


La esencia del truco para bajar el Chorme es que hay que usar Tor. La explicación corta es que Tor permite a sus usuarios comunicarse en Internet de manera anónima. La explicación larga, para los que les interese el lado técnico de Tor, está aquí (inglés) y aquí (español), o también en Wikipedia aquí (inglés) y aquí.

Paso #1: Bajar Tor aquí (inglés) o aquí (español)
Importante: Se debe bajar el primero de la lista, la versión estable.

Paso #2: Instalar Tor. Si estás conectado a Internet directo sin proxy ya Tor debe estar conectado. Si estás conectado a través de un proxy el panel de control de Tor tiene opciones para configurarle a Tor el proxy de tu red local. Me temo que si tu proxy requiere autenticación, va a ser dificil la cosa. Para más información sobre el uso de Tor detrás de Firewalls/Cortafuegos/Proxies/etc haga clic aquí.

Paso #3: Configurar el Internet Explorer con los settings del proxy local que Tor instaló. Tor funciona precisamente habilitando un proxy local en tu máquina. Hay que configurar el Internet Explorer para que utilice este proxy. La configuracion está en el menú Herramientas | Opciones de Internet y deben fijarse en la siguiente imagen para que vean como deben dejar configurado el proxy en el Internet Explorer. Fíjense bien en el orden de los pasos 1, 2, 3, ...

Nota importante: Fíjense que son dos cosas distintas el proxy de su red (si es que hay alguno) y el proxy de Tor, que es el que estamos configurando aquí.

Paso #4: Una vez configurado todo, si lo han hecho todo bien, pueden ir a http://www.google.com/chrome y ya no estará bloqueada la página. Es bueno que sepan que la navegación en Internet a través de Tor es más lenta de lo normal. Si bien ya en Cuba es lenta la cosa, a través de Tor es más lenta aún.

Paso #5: Bajar el ChromeSetup.exe (485k) y ejecutarlo. Este a su vez bajará el verdadero instalador de 7 megas (chrome_setup.exe) y lo ejecutará automaticamente.

Paso #6 (opcional): Si quieren quedarse con el instalador chrome_setup.exe además de tenerlo instalado localmente, en el momento en que les aparece la ventana de opciones de instalación (lamentablemente no tengo screenshot de esto) sin aún aceptar la instalación, lo buscan en algún lugar que ya no recuerdo dentro de c:\Document and settings\username\Configuración Local o en Local Settings si el Windows es en inglés.

Finalizando...


Perdonen la imprecisiones, pero ya hice este procedimiento una vez y no pienso volver a hacerlo. Si alguien tiene éxito con estas instrucciones por favor fíjese bien en estos detalles que me faltan y me lo mandan a decir a mi dirección de email (que les puse más arriba) o publican su propia guía de instalación en su blog, pero por favor, me lo hacen saber, y si me dan algo de crédito no me pongo bravo.

Y recuerden que si alguien conoce cómo y dónde se puede hostear el verdadero instalador del Chrome, el de 7 megas, para que así la gente no tenga que seguir estas instrucciones tan engorrosas.

NOTA IMPORTANTE


Por último, si se percatan, Tor sirve para muchas otras cosas (algunas de ellas bien ocultas y al margen de la ley de algunos lugares). Pero NO ES DE ESO DE LO QUE TRATA ESTE POST. Este post es sencillamente de como jugarle cabeza a una parte incómoda del llamado bloqueo de EE.UU. a Cuba.

EL AUTOR NO SE RESPONSABILIZA DEL USO O MAL-USO QUE LOS LECTORES LE PUEDAN DAR A TOR, COMO TAMBIEN DESCONOCE LAS IMPLICACIONES LEGALES DE USAR EL SOFTWARE TOR DENTRO O FUERA DE CUBA. TODO EL QUE SIGA ESTAS INSTRUCCIONES, O QUE A PARTIR DE ELLAS IMPROVISE PARA ESTE U OTROS USOS, LO HACE BAJO SU PROPIA RESPONSABILIDAD.

Perdonen la muelita bizca y legal, pero hay que seguir el ejemplo de Poncio el Piloto.

Chrome (aka Cuba blocked by Google)

, ,

I was very excited on Monday when I learned that Google was about to release a new web browser of their own, dubbed Google Chrome. It was about time!

But soon after the initial excitement that the announcement comic made me feel, I remembered that for a long time now Google has been blocking all their downloads from Cuba. This includes all their applications (Google Talk, Google Earth, Google Desktop, Picasa, Google Pack, etc.) and every single piece of code available via the Google Code portal. And I did not hesitate a moment before I knew that Chrome was not going to be an exception, not even for the fact that, unlike all other Google applications, Chrome is an open source project. It seems that for Google free software is only for those who are considered to be free by the US state department.

And I wonder how much is Google obliged to treat Cubans this way, when many other companies just as prominent, visible and American as Google is (for instance Yahoo! and Microsoft) are not blocking any of their freeware downloads from this island. And I hope this observations would not lead them to copy Google's policy, but the other way around.

But anyway, I managed to grab a copy of Chrome using unspeakable methods. The simple approach of having someone abroad download it and send it to me via email or something, it won't work. The direct download is just a small program that does the rest of the download itself. And guess what, this program also checks where I am connected from.

But thanks to some hacking (hint: operator) I was able to have it, and test it, and taste it. And as almost anything Google-made (except of course their downloads policy) is delicious. Here are my impressions, trying to focus on the things that have been less visible in most reviews.

An Opera clone?


According to its visual features, yes. Tabs as first-class independent citizens, speeddial-like initial page, UI responsiveness, particularly when switching tabs, are the most prominent features that remind us of Opera. But as Opera's CEO put it, this is flattering for Opera. And it's good indirect publicity too.

But as true as it is that Opera excels Chrome in UI configurability and dinamicity, Chrome has some very good innovations in its inner workings, like separate processes for each tab, javascript-to-native-code, and sandboxing. From a software programmer's perspective I can see that these things are here to stay and even to get into other browsers' design choices in the near future. What's good is good. And maybe someone else (hopefully Opera) can innovate further on these.

Speed-dial, History and Downloads tabs


While not exactly brand new features in the browsers' world, Chrome's implementation of these have the taste of innovation too. Speed-dial incorporates a couple of dynamic components (search boxes and recently closed tabs) and it also has a look that mimics Google websites and pages, making it look like you're already in a website that serves as a gate for other sites. Making it look like you're at Google already.

Similar things can be said of the history and downloads tabs, both having a search box at the top, which mimics those of Google's own web sites. As trivial and simple as this might seem, I find it very important for the overall feeling and taste that this new browser leaves on us.


Minor goodies


I felt amused by the omnibar's highlighting of the domain, leaving the rest of the URL dimmed in a lighter color. For people like me that appreciate knowing in a glimpse where I am standing when watching a page, this is very helpful. I was also worried about the lack of status bar, which lets me know where a link points to before I actually click on it. It turns out that Chrome has a small "status bar" that appears on demand to give us this kind of information, but that silently goes away after a few seconds.

The search feature, the one that lets us search within the text of a loaded page, also works similarly to that of Firefox (but in the top right instead of the bottom). The search box appears when we ask for it (with Ctrl+F) and then it goes away when we're finished. This kind of unobtrusive goodies are some of the things that Opera still lacks.

And I also noticed something that nobody else told me about Chrome in my extensive reviews and reading prior to my own use of it: it has a spell checker! This very post is being spell-checked by it as I write, much in the vein of Firefox's spell checker. Although to be honest, it is still slow, freezing my cursor a fraction of a second just after I finish writing a misspelled word. Sure there's home for improvement here, also allowing bilingual users like me to have more than one dictionary available.

Do's and Dont's


One thing I'd like is something I've been talking about for a long time, and that Opera finally made it real: synchronizing my settings (bookmarks, etc.) with a central store, so that I have my stuff wherever I may use Chrome. This could even be incorporated to Firefox via an extension, so that transition between Chrome and Firefox would be much easier. It would be much better if all major browsers would agree on this, develop a standard for this, and everybody wins (except Microsoft, of course)

On the other hand, among the things I would not like, I would specially hate if they make an extension architecture like Firefox's XUL. It just bloat the whole thing. Remember the KISS principle: Keep It Simple, Stupid!

My overall feeling about it


As a user and crawler of the web myself (albeit a technically inclined one), Chrome is as good as I can expect from a first release, and it already makes me expect new things from other browsers more established in my day-to-day pack of tools. Sure it has some road ahead (which project does not, particularly when it's new) but in the most basic features it is indeed a great new kid on the block.

As a web developer, it's good to have something handy to test my stuff with webkit, since I do not own a Mac but although Chrome has some basic developer tools, it is still light-years behind Firebug. Even Dragonfly is behind Firebug.

Overall, I am happy to have a new contender that re-ignites an already active browsers war. Competition and innovation in the end are good for us internet users. Let them compete to gain our preference. Sit back and watch the fight!

Ubuntu web page broken in Opera

, , , ...

Is it Opera's fault or the CSS styling of the Ubuntu web site is non-standard? Have you noted that the tabs at the top right are unaligned when seen in Opera, but are ok seen from IE and Firefox?

From Opera



From Firefox



Update (July 2)

A good fellow member of this community, whose blog is devoted to Opera and web pages compatibility with this browser, tells me that...

this is a known bug and described as "floated list item children of inline list child of an absolutely positioned element are not displayed on one line".

...it is even considered quite important (probably mainly because of it appearing on the Ubuntu website)

So it is unfortunately a bug in Opera, and not a bug in Ubuntu's web site coding. I hope this bug will get fixed soon.

Back and more human

, , ,

Yes, after a long while, I am back. And more human because I have found my ideal computing environment in the most human of all Linux distributions, Ubuntu, and the most human of all browsers, Opera.

There are numerous new softwares and web applications that have appeared or been upgraded during this weeks that I've been off. I will try to talk about all these in the next days, emphasizing on Opera, which arrived to its ninth version last Tuesday, and is better than ever. I will emphasize also on the use of Linux and Ubuntu Dapper Drake in particular.

Also, I wanted to note that on next Monday, June 26, it will be a year since my first post, which was originally made when my blog was blogger-based.

Opera remains unique in out-of-the-box features

, , , ...

It is absolutely incredible, but I've always needed a feature from Opera related to tabbed browsing. Wait, I know you would like to know so I'll tell you through the following (common) scenario.

I start browsing in the morning. I am eager to know about what's going on out there in the world so I go and get some news about the topics I'm interested in. I open Google Reader (my aggregator of choice), Google News and Yahoo News. A rapid glimpse through the immense amount of hyperlinked headlines generates a myriad of middle clicks to open in background tabs whatever seems interesting. Before I'm actually aware of it, I have twenty to thirty tabs in a single Opera window. I don't know you, but I don't like more than a dozen tabs together. Too much clutter.

What if I could move some of the tabs to a second (or even a third) window? Well, I realized today that I've always assumed this wasn't possible. I always looked for an option in the contextual menu you get when you right-click a tab, and I didn't find any. Don't ask me why (and you may call me a fool) but I thought today, what if I create another Opera window and drag some tabs into its tab bar? Voila! Eureka!

I haven't seen this feature in any other browser. Firefox didn't even have the plain and simple drag-and-drop of tabs within a single window until the latest 1.5 release (It had and extension, though).

It is amazing how Opera manages to give so many little but useful features out of the box. It is these little things that make this little browser so great. What? You want to know some other cool stuff?

  • No need to restart to change the skin
  • Session management
  • The links and info panels
  • The [extensible and customizable] search panel
  • Custom panels
  • Full customizability of toolbars layout
  • The ability to recover tabs closed accidentally
  • The "Fit to window width" button
  • Small-screen rendering
  • Zoom (instead of just changing the text size)
  • The [magic] wand (there's just no other one like it)
  • Voice
  • Notes
  • Fast-forward and rewind.
  • You name it...
and if this is not enough, check out this wonderful collection of custom Opera buttons that are able to put any imaginable functionality just a click away.

Before I finish, I'd like to make a request. If you are familiar with any obscure and not-so-known ability of this mighty browser, and you happen to be reading this, please, let us all know about it.

The DRY principle (or Don't Repeat Yourself)

, ,

I recall that some days ago I was searching for information about VLANs and I got a considerable amount of different pages open in Opera at the same time, all related to this subject. But then I had to stop working on it. I don't remember if I was at work and was time to leave home, or if I was already at home and had to stop for some other reason. The thing is that I saved the configuration of all open tabs in a browser session.

A few minutes ago I was ready to continue working on it, because I desperately need to set up some CISCO switches to work out some VLANs. Our network is rapidly growing and bringing some order into it is now more than a mere whim for us here in the IT department. But guess what: my sessions do not include the session on VLANs that I perfectly remember. The problem is that I have four Opera instances of my own. I work on two computers regularly: one at work and one at home, and to worsen the scenario, each with both Windows and Linux installed. It is to drive anyone crazy, believe me.

I've written before about the idea of storing Opera configuration files online, as part of the user's profiles in the Opera Community. These might include layout configuration (toolbar, menus, panels), user information (sessions, bookmarks, notes, contacts) and maybe wand, history or other pieces of sensitive data with the inevitable security and privacy concerns being appropriately addressed.

To this crazy quadruple setup you should add that I re-install Windows every six months at most, and every time I do this I have to work out my layout again, which is by the way very different from the default Opera layout (a single top toolbar, status bar on, panels on right, menu bar off, custom panels, custom search engines and more). Also, with the advent of the yet-to-come Opera 9, per-site configurations will become a real headache to maintain.

There's this principle in programming called the DRY principle: Don't Repeat Yourself. And I feel like I'm repeating myself every time I have to re-work my Opera environment to fit my needs again. The idea of integration between My Opera user profiles and the browser is not new and it's not mine, but it's great. What do you think?

Opera Labs "cooking" the future

, , ,

I was coincidentally writing yesterday about my expectations on the Opera Web Browser and particularly on its next version yet to come. And today Opera Software has started a very original and promising initiative called Opera Labs. There are no better words to describe it than Opera's own words.

[...]a behind-the-scenes look at the latest technology and products from Opera Software.

And guess what's the first look that we get from behind-the-scenes: the latest tech preview of the upcoming Opera 9. It offers some new features, such as Bittorent support, Widgets and minor UI improvements.

Among other highlights from this new site is the web standards page, which gives a brief but useful speech about what are web standards, why are they so important today and how can they help us in the future.

Opera Software is committed to a standards-based web. This is important because it allows tools to be developed to work with the web in new contexts, something Opera does often. Working with other browser developers, content producers, user groups, researchers, and others allows everyone to look at the new ideas coming up, make sure that they will work across the entire web, and produce a specification that anyone can implement. This is the fundamental reason Opera is a member of W3C, and further sponsors W3C activity in important areas.

In spite of everything being said on the web, about Firefox, IE or whatever, Opera is still the most innovative web browser, and the most innovative web product available.

This is of course, my humble opinion. You may freely and respectfully disagree.



PS: I haven't verified it yet, but I swear that Opera 8.5 was worse in the Acid2 Test. Opera 9 renders it almost like the reference rendering.

A gap I wouldn't like Opera to get in

, , , ...

It's always sad when a web site explicitly states that it doesn't support a certain browser. Phrases like "this page is best viewed in Internet Explorer 5 or above" always annoy me a little. And now with all this Firefox hype, the same thing happens with this alternative web browser. Firefox fan-boys are now populating the web with "Best viewed in Firefox 1+" kind of pages. I guess this is an attempt to fight IE back, after all these years, but they're also hurting the rest of the browsers, and they're doing exactly what most of this advocates criticized.

I would love Opera becoming mainstream in the desktop browser market, but if this ever happens, I wouldn't like web sites developing pages that are "best viewed" in Opera. Browser choice should be something about browser features, speed, stability, security and the like. It shouldn't be a matter of compatibility with web sites. But anyway, there are so many things wrong in this world, that asking for some justice in browser-land is definitely not a priority.

Why all this rant? you may wonder. Well, I was intending to visit Gap Online, and I didn't find what I expected. Instead, this is what I got
The relevant part of the message literally says

We're sorry, but we do not support the version of the browser you are using.
Our site works best with the following browsers:

PC users
Internet Explorer 5.5 and above. Click here to download the latest browser.
Netscape 7 and above. Click here to download the latest browser.
Mozilla (including Firefox) 1.0 and above. Click here to download the latest browser.

Mac users
Netscape 7 and above. Click here to download the latest browser.
Mozilla (including Firefox) 1.0 and above. Click here to download the latest browser.
Safari 2.0.3* and above. Click here to update your browser.

And what did I do? I do have Firefox installed, and I have access to a Windows box where I could have used the brand old ever-buggy and platform-dependent Internet Explorer 6. But I didn't. I restrained myself from visiting this site.

Update
I reported this problem with Gap Online in the "Open the Web" forum.
