Costales: Destino Ubuconla 2014 - #11 The End

Fri, 2014-08-29 18:27
Antes del viaje todo el mundo me advertía de que Colombia es un país muy peligroso para el turista... ¡Colombia... ays Colombia! ¡Qué país! El viajero encontrará paisajes extraordinarios, vertiginosas ciudades llenas de historia grabada a fuego durante siglos, una gastronomía exquisita y su gente que hace a este país especial, al ritmo de su música rumbera, abiertos, alegres y muy hospitalarios. Como bromean por aquí, el peligro es que te quieras quedar :P

perdiéndose por los mercados callejeros
de sus callesy disfrutando el alma de este pueblocon sus junglas de asfaltoy sus junglas reales(jue con la 'hormiguita')... hasta el infinito y más allá
Del viaje en particular podría destacar muchísimas cosas, las playas, las islas, los pueblos, las ciudades, la gastronomía, incluso el calor sofocante; pero no, no voy a destacar nada de todo eso.
Destaco los momentos únicos con personas únicas, que hicieron de este viaje, un viaje único ;) ¡Gracias a todos/as! ¡Hasta la próxima!

Next station? El destino dirá
Todas las entradas del viaje:

Gracias a todos/as por 'acompañarnos' en este relato
... The end ...

Costales: Destino Ubuconla 2014 - #10 Lisboa

Fri, 2014-08-29 17:04
Engullimos como patos el extraordinario desayuno buffet. El motivo no es otro que teníamos el tiempo muy justo por salir temprano el avión.


Antes de despegar de Bogotá Avianca nos obligó a pagar el ESTA americano (14$), en caso contrario, la multaban.
Tras aterrizar en la ciudad de Dexter Morgan debemos entregar 'voluntariamente' pasaporte, datos personales, declaración de aduana, declaración ESTA, que nos tomen las huellas dactilares y foto... ¡Ni mi propio gobierno sabe ahora tanto de mi como USA! Y eso que sólo queríamos cambiar de avión.
También me sorprendieron las cámaras en el aeropuerto, una cada 20m.
En Bogotá nos habían dicho que el equipaje lo recogíamos en Lisboa, pero nos enteramos de casualidad de que había que cogerlo en la cinta de maletas de Miami para llevarlo a un mostrador a 50m ?:O No quedaron las maletas en Miami de milagro.

Y tras el vuelo de 7 horas y pico de avión desde Miami, llegamos a Lisboa.
La capital estaba amaneciendo y prestó pasear sus calles y plazas desiertas.
¿Dónde está la gente?
Eso sí, durante demasiadas horas nuestro radio de acción consistió en 250m desde el punto de información turística (la razón no es otra que nuestra diarrea seguía a su ritmo y ahí había un baño público de pago).
(:   [TSA|TP] + NEDescansamos en el hotel toda la tarde, posiblemente debido al jetlag. Y a la hora de cenar disfrutamos de sardinas y bonito, acompañados de un excelente vino verde.

Intentando olvidar el jetlagAl día siguiente tocó volver p'Asturies, tras un viaje exprimido hasta en su último minuto, pero ese resumen pertenece al post final :)

Ñam, ñam...
Al otru lláu de la mar... Colombia :)
Y nos encontramos con el día más caluroso del año

Daniel Pocock: Welcoming libphonenumber to Debian and Ubuntu

Fri, 2014-08-29 08:02

Google's libphonenumber is a universal library for parsing, validating, identifying and formatting phone numbers. It works quite well for numbers from just about anywhere. Here is a Java code sample (C++ and JavaScript also supported) from their web site:


String swissNumberStr = "044 668 18 00";
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
  PhoneNumber swissNumberProto = phoneUtil.parse(swissNumberStr, "CH");
} catch (NumberParseException e) {
  System.err.println("NumberParseException was thrown: " + e.toString());
}
boolean isValid = phoneUtil.isValidNumber(swissNumberProto); // returns true
// Produces "+41 44 668 18 00"
System.out.println(phoneUtil.format(swissNumberProto, PhoneNumberFormat.INTERNATIONAL));
// Produces "044 668 18 00"
System.out.println(phoneUtil.format(swissNumberProto, PhoneNumberFormat.NATIONAL));
// Produces "+41446681800"
System.out.println(phoneUtil.format(swissNumberProto, PhoneNumberFormat.E164));

This is particularly useful for anybody working with international phone numbers. This is a common requirement in the world of VoIP where people mix-and-match phones and hosted PBXes in different countries and all their numbers have to be normalized.

About the packages

The new libphonenumber package provides support for C++ and Java users. Upstream also supports JavaScript but that hasn't been packaged yet.

Using libphonenumber from Evolution and other software

Lumicall, the secure SIP/ZRTP client for Android, has had libphonenumber from the beginning. It is essential when converting dialed numbers into E.164 format to make ENUM queries and it is also helpful to normalize all the numbers before passing them to VoIP gateways.

Debian includes the GNOME Evolution suite and it will use libphonenumber to improve handling of phone numbers in contact records if enabled at compile time. Fredrik has submitted a patch for that in Debian.

Many more applications can potentially benefit from this too. libphonenumber is released under an Apache license so it is compatible with the Mozilla license and suitable for use in Thunderbird plugins.

Improving libphonenumber

It is hard to keep up with the changes in dialing codes around the world. Phone companies and sometimes even whole countries come and go from time to time. Numbering plans change to add extra digits. New prefixes are created for new mobile networks. libphonenumber contains metadata for all the countries and telephone numbers that the authors are aware of but they also welcome feedback through their mailing list for anything that is not quite right.

Now that libphonenumber is available as a package, it may be helpful for somebody to try and find a way to split the metadata from the code so that metadata changes could be distributed through the stable updates catalog along with other volatile packages such as anti-virus patterns.

Robert Collins: Test processes as servers

Fri, 2014-08-29 04:10

Since its very early days subunit has had a single model – you run a process, it outputs test results. This works great, except when it doesn’t.

On the up side, you have a one way pipeline – there’s no interactivity needed, which makes it very very easy to write a subunit backend that e.g. testr can use.

On the downside, there’s no interactivity, which means that anytime you want to do something with those tests, a new process is needed – and thats sometimes quite expensive – particularly in test suites with 10’s of thousands of tests.Now, for use in the development edit-execute loop, this is arguably ok, because one needs to load the new tests into memory anyway; but wouldn’t it be nice if tools like testr that run tests for you didn’t have to decide upfront exactly how they were going to run. If instead they could get things running straight away and then give progressively larger and larger units of work to be run, without forcing a new process (and thus new discovery directory walking and importing) ? Secondly, testr has an inconsistent interface – if testr is letting a user debug things to testr through to child workers in a chain, it needs to use something structured (e.g. subunit) and route stdin to the actual worker, but the final testr needs to unwrap everything – this is needlessly complex. Lastly, for some languages at least, its possibly to dynamically pick up new code at runtime – so a simple inotify loop and we could avoid new-process (and more importantly complete-enumeration) *entirely*, leading to very fast edit-test cycles.

So, in this blog post I’m really running this idea up the flagpole, and trying to sketch out the interface – and hopefully get feedback on it.

Taking subunit.run as an example process to do this to:

  1. There should be an option to change from one-shot to server mode
  2. In server mode, it will listen for commands somewhere (lets say stdin)
  3. On startup it might eager load the available tests
  4. One command would be list-tests – which would enumerate all the tests to its output channel (which is stdout today – so lets stay with that for now)
  5. Another would be run-tests, which would take a set of test ids, and then filter-and-run just those ids from the available tests, output, as it does today, going to stdout. Passing somewhat large sets of test ids in may be desirable, because some test runners perform fixture optimisations (e.g. bringing up DB servers or web servers) and test-at-a-time is pretty much worst case for that sort of environment.
  6. Another would be be std-in a command providing a packet of stdin – used for interacting with debuggers

So that seems pretty approachable to me – we don’t even need an async loop in there, as long as we’re willing to patch select etc (for the stdin handling in some environments like Twisted). If we don’t want to monkey patch like that, we’ll need to make stdin a socketpair, and have an event loop running to shepard bytes from the real stdin to the one we let the rest of Python have.

What about that nirvana above? If we assume inotify support, then list_tests (and run_tests) can just consult a changed-file list and reload those modules before continuing. Reloading them just-in-time would be likely to create havoc – I think reloading only when synchronised with test completion makes a great deal of sense.

Would such a test server make sense in other languages?  What about e.g. testtools.run vs subunit.run – such a server wouldn’t want to use subunit, but perhaps a regular CLI UI would be nice…


The Fridge: Ubuntu 14.10 (Utopic Unicorn) beta-1 released!

Thu, 2014-08-28 21:56

The first beta of the Utopic Unicorn (to become 14.10) has now been released!

This beta features images for Kubuntu, Lubuntu, Ubuntu GNOME, UbuntuKylin, Xubuntu and the Ubuntu Cloud images.

Pre-releases of the Utopic Unicorn are *not* encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage. They are, however, recommended for Ubuntu flavor developers and those who want to help in testing, reporting and fixing bugs as we work towards getting this release ready.

Beta 1 includes a number of software updates that are ready for wider testing. This is quite an early set of images, so you should expect some bugs.

While these Beta 1 images have been tested and work, except as noted in the release notes, Ubuntu developers are continuing to improve the Utopic Unicorn. In particular, once newer daily images are available, system installation bugs identified in the Beta 1 installer should be verified against the current daily image before being reported in Launchpad. Using an obsolete image to re-report bugs that have already been fixed wastes your time and the time of developers who are busy trying to make 14.10 the best Ubuntu release yet. Always ensure your system is up to date before reporting bugs.

Kubuntu

Kubuntu is the KDE based flavour of Ubuntu. It uses the Plasma desktop and includes a wide selection of tools from the KDE project.

Kubuntu development is now focussing on the next generation of KDE Software, Plasma 5. This is not yet stable enough for everyday use, so our default option is the trusted Plasma 4 desktop. A tech preview of Plasma 5 is available for those who want to try out the future.

The Beta-1 images can be downloaded at:

Canonical Design Team: Saving ubuntu.com on download day – caching location specific pages

Thu, 2014-08-28 18:34

On release day we can get up to 8,000 requests second to ubuntu.com from people trying to download the new release. In fact, last October (13.10) was the first release day in a long time that the site didn’t crash under the load at some point during the day (huge credit to the infrastructure team).

Ubuntu.com has been running on Drupal, but we’ve been gradually migrating it to a more bespoke Django based system. In March we started work on migrating the download section in time for the release of Trusty Tahr. This was a prime opportunity to look for ways to reduce some of the load on the servers.

Choosing geolocated download mirrors is hard work for an application

When someone download Ubuntu from ubuntu.com (on a thank-you page), they are actually sent to one of the 300 or so mirror sites that’s nearby.

To pick a mirror for the user, the application has to:

  1. Decide from the client’s IP address what country they’re in
  2. Get the list of mirrors and find the ones that are in their country
  3. Randomly pick them a mirror, while sending more people to mirrors with higher bandwidth

This process is by far the most intensive operation on the whole site, not because these tasks are particularly complicated in themselves, but because this needs to be done for each and every user – potentially 8,000 a second while every other page on the site can be aggressively cached to prevent most requests from hitting the application itself.

For the site to be able to handle this load, we’d need to load-balance requests across perhaps 40 VMs.

Can everything be done client-side?

Our first thought was to embed the entire mirror list in the thank-you page and use JavaScript in the users’ browsers to select an appropriate mirror. This would drastically reduce the load on the application, because the download page would then be effectively static and cache-able like every other page.

The only way to reliably get the user’s location client-side is with the geolocation API, which is only supported by 84% of users’ browsers. Another slight issue is that the user has to give permission before they could be assigned a mirror, which would slightly hindering their experience.

This solution would inconvenience users just a bit too much. So we found a trade-off:

A mixed solution – Apache geolocation

mod_geoip2 for Apache can apply server rules based on a user’s location and is much faster than doing geolocation at the application level. This means that we can use Apache to send users to a country-specific version of the download page (e.g. the German desktop thank-you page) by adding &country=GB to the end of the URL.

These country specific pages contain the list of mirrors for that country, and each one can now be cached, vastly reducing the load on the server. Client-side JavaScript randomly selects a mirror for the user, weighted by the bandwidth of each mirror, and kicks off their download, without the need for client-side geolocation support.

This solution was successfully implemented shortly before the release of Trusty Tahr.

Zygmunt Krynicki: Checkbox Project Insights

Thu, 2014-08-28 17:40
Another day behind us. Another day hacking on the Checkbox Project.

Today we got a few issues on the 3.2 SRU kernel for precise. I've recorded a short explanation of how the SRU process looks like from our (Certification) perspective. We're investigating those to see if those are kernel problems or test bugs.

I've started the day by working on a few code reviews and SRU reviews. The bulk of the time was spent on the new validation subsystem for Checkbox. As before, you can see most of that via the Live Coding videos, specifically episodes #17, #18, #19 and #20) on my YouTube channel.

You can always find us, checkbox hackers in #checkbox on freenode. If you care about testing hardware with free software, join us!

Costales: Destino Ubuconla 2014 - #9 Bogotá

Thu, 2014-08-28 16:13
Fartamos el desayuno buffet con la idea de comer ligero, porque llegamos tarde a Bogotá y así exprimir más el poco tiempo que estuvimos en la capital de Colombia.

Perdida toda la mañana con el vuelo aéreo llegamos al hotel. Jugo de recepción, una habitación casi tan grande como una casa, jacuzzi, piscina, bar... A mirar y no tocar jajaja, no vayamos a acostumbrarnos a este nivel :P (Y mañana toca hostal en Lisboa, ¡LOL!)

Poco más hicimos en Bogotá que salir a buscar unos regalos, pero la ciudad es tan grande, que tardas muchísimas horas yendo de un punto a otro.
Una pena no haber podido tener más días para conocer BogotáConseguimos estar de vuelta justo al anochecer. Y tachán, invitados a unos jugos y a cenar :O Al final va a salir barato el hotelito :P
Jugos, jugos y más jugos, ¡están impresionantes!Al no tener el ESTA americano, Avianca no nos permitió hacer el checkin online. Por tener que estar muy temprano en el aeropuerto, lo rellenamos por Internet, pero no lo pagamos (14$/persona).

El resto de la noche tocó disfrutar del lujoso hotel.

Xubuntu: inxi

Thu, 2014-08-28 16:01

inxi is a full featured system information script that will detect information about hardware specifications, including but not limited to vendor details, CPU info, graphic and sound cards. Most importantly, it will output everything in a easy to read format and it can also be used on irc clients like irssi, weechat or xchat.

How to use inxi?

The general use of inxi is inxi -<color> -<option>. inxi output is colored and to change the color for better visibility use the c option followed by a number between 0-32.

Information type Command, usage, and more information System information inxi -b and inxi -F
The b option output basic system information, while the F option will output full system information. Hard drive details inxi -D
Outputs information on your hard drives, like make, model and size Hard drive partitions inxi -p
Outputs information about all mounted partitions, mount points and space usage Networking inxi -n and inxi -ni
Outputs information about the details of the network interfaces and configuration. When the i option is used with n, Inxi will output IP address details (for both WAN and LAN). Hardware inxi -AG and inxi -h
The A and G options output information about the audio and graphics hardware respectively. You usually want to use them together. The h option outputs you the full list of options you can use to get even more information about your hardware. Using inxi in IRC clients Client Usage Xchat, irssi and most other clients /exec -o inxi -<option> | pastebinit
The -o option shows the output to the channel. Without it, only the user will see the output. Weechat /shell -o inxi -<option> | pastebinit
Note: For weechat to run external scripts like inxi, shell.py has to be installed.

Using inxi -c0 within a IRC client environment is highly advisable because colored output doesn’t work in pastebins.

Xubuntu: Laptop users, Fix available for the black screen on unlock bug

Thu, 2014-08-28 11:11

If you experienced problems with logging into your session after suspending your laptop by closing the lid (and only this exact scenario!), your days of worry should be over now. Many users have commented on the respective bugreport, many of whom experienced different issues with suspending. This made the issue very difficult to pinpoint in the beginning for us technical folk and confusing for users too.

Sean Davis, Technical Lead of Xubuntu, put together the pieces we collected after identifying the issue and the fix landed in the 14.04.1 and 14.10 Beta 1 releases. This means that the problem is fixed for

  • New installs of Xubuntu 14.04.1 or Xubuntu 14.10 Beta 1
  • New users created with xubuntu-default-settings 14.04.5

All those of you who have been running Trusty since its release have to toggle a setting in order to fix the issue for existing user-accounts:

  1. Open Light Locker Settings from the Settings Manager
  2. Turn “Enable Light Locker” Off. Click “Apply”.
  3. Turn “Enable Light Locker” On. Click “Apply”.

These steps have to followed manually because we never overwrite existing user settings.
Obviously, if you previously had disabled Light Locker, the last step is sufficient.

Charles Butler: Juju <3's Big Data

Wed, 2014-08-27 21:06

Syndicators, there is a video link above that may not make syndication. Click the source link to view the 10 minute demo video.

Over the past 4 months Amir Sanjar and I have been working dilligently on Juju's Big Data story. Working with software vendors to charm up big name products like the Demo'd Hortonworks Hadoop distribution.

To those of you that know nothing about Hadoop - Hadoop is a large scale big data framework / suite of applications. It provides facilities to build an entire ecosystem to crunch numbers from seemingly unrelated data sources, and compute through petabytes of data via Map/Reduce applications.

A traditional hadoop deployment consists of a few components:

  • Map / Reduce Engine (or cluster of engines)
  • Data Warehousing Facility
  • Distributed Filesystem to cache results across the cluster

Setting up these different services and interconnecting them can be a full day process for a seasoned professional in the Big Data ecosystem. Juju offers you a quick way to distill all of that setup and interconnectivity knowledge so you can be a master at USING hadoop. Not at deploying it.

Some people say Juju negates the need to read the book, and while this may be true; I still advise you read the book at least once - so you know how it's put together, why certain configurations were chosen, and how to troubleshoot the bundle should anything go wrong. Then you're free to wield the community provided Hadoop bundle(s) like a pro.

Enjoy the Demo, and look for more Big Data tools and products on the Juju Charm Store
