Gervase Markham: Top 50 DOS Problems Solved: Whoops, I Deleted Everything

do, 16/04/2015 - 10:20

Q: I accidentally deleted all the files in the root directory of my hard disk for the second time this month. I managed to reinstall everything, but is there a way of avoiding the problem?

A: There are two approaches you could try, both of which have applications for other things too:

  • Modify the files so that they cannot be deleted without first explicitly making them deletable. You can do this with the DOS utility Attrib which was supplied with your system. … To protect the file use the command:

    ATTRIB +R filename

    The +R switch means “make this file read-only”.

  • Stop using the DEL command to delete files. Use a batch file instead which will prompt you before taking action.

    … <batch file code is given> …

    This batch file has a useful enhancement beyond the precautionary message. You can use it to specify multiple files, for example:


    With one command this would delete all .BAK files, FRED.BAS, and all .DOC files whose names begin with a single letter.

A delete command which takes multiple arguments – wow…

Soledad Penades: Running a web server on the front-end

wo, 15/04/2015 - 13:51

The introduction of TCP sockets support in Firefox OS made it possible to run a web server from the front-end, and all is written in JavaScript. Think of having something similar to express.js… but running on a browser (because after all, Firefox OS is a superturbocharged browser).

Again, JS server superstar Justin d’Archangelo wrote an implementation of a web server that works on Firefox OS. It’s called fxos-web-server and it includes a few examples you can run.

None of the examples particularly fit my use case–I want to serve static content from a phone to other phones, but the examples were a bit more contrived. So I decided to build a simpler proof-of-concept example: catserver, a web server that served a simple page with full screen Animated GIFs of cats:


The first thing I wanted to do is to use Browserify “proper”, to write my app in a more modular way. For this I had to fork Justin’s original project and modify its package.json so it would let me require() the server instead of tucking its variable in the window globals :-) – sadly I yet have to send him a PR so you will need to be aware of this difference. The dependency in package.json points to my fork for now:

"fxos-web-server": "git+" Building (with gulp)

My example is composed of two “websites”. The first one is the web server app itself which is what is executed in the “server” device. The sources for this are in src.

The second website is what the server will transfer to devices that connect to it, so this actually gets executed in the client devies. This is where the cats are! Its contents are in the www folder.

Both websites are packaged in just one ZIP file and then installed onto the server device.

This build process also involves running Browserify first so I can get from node-style code that uses require() to a JavaScript bundle that runs on Firefox OS. So I’m using gulp to do all that. The tasks are in gulpfile.js.

Web server app

Thanks to Justin’s work, this is fairly simple. We create an HTTP server on port 80:

var HTTPServer = require('fxos-web-server');
var server = new HTTPServer(80);

And then we add a listener for when a request is made, so we can respond to it (and serve content to the connected client):

server.addEventListener('request', function(evt) {
      var request = evt.request;
      var response = evt.response;

      //... Decide what to send

The “decide what to send” part is a bit like writing nginx or express config files. In this case I wanted to:

  • serve an index.html file if we request a “directory” (i.e. a path that ends with “/”)
  • serve static content if we request a file (i.e. the path doesn’t end with “/”)

Before serving a file we need to tell the client what kind of content we’re sending to it. I’m using a very simple “extension to content type” function that determines MIME types based on the extension in the path. E.g. ‘html’ returns text/html.

Once we know the content type, we set it on the response headers:

response.headers['Content-Type'] = getContentType(fileToSend);

and use Justin’s shortcut function sendFile to send a file from our app to the client:


With the request handler set up, we can finally start the server!

server.start(); But… how does it even work?!

Welcome to the Hack of The Week!

When you say “sendFile” what the server app does is: it creates an XMLHttpRequest with type = arraybuffer to load the raw contents of the resource. When the XMLHttpRequest emits the load event, the server takes the loaded data and sends it to the client. That’s it!

Naive! Simple! It works! (for simple cases)

Ways that this could be improved – AKA “wanna make this better?! this is your chance!”

As I mentioned above, right now this is very naive and assumes that the files will exist. If they don’t, well, horrible things will happen. Or you will get a 404 error. I haven’t tried it myself. I’m not sure. I’d say there is no error handling (yet).

The extension to content type function could be made into a module, and probably extended to know about more file types. It probably exists already, somewhere in npmlandia.

Another idea I had is that instead of loading the entire resource in memory and then flush it down the pipe as sendFile does, we could use progress events on the XMLHttpRequest and feed it to the client as we load it–so that the server device won’t run out of memory. I don’t know how we could find the length of the resource first, perhaps a HEAD request could work!

And finally we could try to serve each request in a worker, so that the server doesn’t block when responding to a large request. Am I going too far? I don’t even know if the TCP sockets work with workers, or if there are issues with that, or who knows!? This is unexplored territory, welcome to Uncertainty Land! :-D

Even extremer ways to get very… “creative”

What if you wrote a PHP parser that runs in JavaScript and then parsed .php files instead of just returning their contents as text/html?

I’m only half kidding, but you could maybe execute JS templates on the server. Forget security! You trust the content, right? ;-)

Another thing you could do is take advantage of the fact that the server is also a browser. So you can do browsersy things such as using Canvas to generate images, instead of having to load libraries that simulate canvas in node. Or you could synthesise web audio stuff on demand–maybe you could use an OfflineAudioWorker for extra non-blocking goodness! Or, if you want to go towards a relatively more boring direction, you could do DOM / text handling on a server that can deal with that kind of stuff natively.

With all the new platforms in which we can run Firefox OS, there are so many things we can do! Phone servers might be limited by battery, but a Raspberry PI running Firefox OS and connected to a power source can be an interesting platform with which to experiment with this kind of easy-to-write web servers.

But I saw NFC mentioned in the video!

Indeed! But I will cover that in another post, so we keep this one focused on the HTTP server :-)

Happy www serving!

flattr this!

Eitan Isaacson: (re)Introducing eSpeak.js

wo, 15/04/2015 - 04:44

Look! A flashy demo with buttons!


A long time ago, we were investigating a way to expose text-to-speech functionality on the web. This was long before the Web Speech API was drafted, and it wasn’t yet clear what this kind of feature would look like. Alon Zakai stepped up, and proposed porting eSpeak to Javascript with Emscripten. This was a provocative idea: was our platform powerful enough to support speech synthesis purely in JS? Alon got back a few days later with a working demo, the answer was “yes”.

While the speak.js port was very impressive, it didn’t answer many of our practical needs. For example, the latency was not good enough for making a responsive UI, you could wait more than a couple of seconds to hear a short phrase. In addition, the longer the text you wanted to synthesize, the longer you needed to wait.

It proved a concept, but there were missing pieces we didn’t have four years ago. Today, we live in the future of 2011, and things that were theoretical then, are possible now (in the future).


Today, Emscripten will compile C/C++ code into a subset of Javascript called asm.js. This subset is optimized on all current browsers, and allows performance to be about 2x native. That is really good. eSpeak is a pretty lightweight library already, the extra performance boost of asm.js makes speech instantaneous.

Transferable Objects

Passing data between a web worker and a parent process used to mean a lot of copying, since the worker doesn’t share memory with the parent process. But today, you can transfer ownership of ArrayBuffers with zero copying. When the web worker is ready to send audio data back to the calling process, it could do so while maintaining a single copy of the audio buffer.

Web Audio API

We have a slick, full featured Audio API today on the web. When speak.js came out in 2011, it used a prefixed method on an <audio> element to write PCM data to. Today, we have a proper API that enables us to take the audio data and send it through an elaborate pipeline of filters and mixers, or even send it into the ether with WebRTC.

Emscripten Got Fancy

This was my first time playing with it, so I am not sure what was available in 2011. But, if I have to guess, it was not as powerful and fun to work with. Emscripten’s new WebIDL support makes adding bindings extremely easy. You still get a chance to do some pointer arithmetic, but that’s supposed to be fun. Right?

So here is eSpeak.js!

I wanted to do a real API port, as opposed to simply porting a command line program that takes input and writes a WAV file. Why? two main reasons:

  1. eSpeak can progressively synthesize speech. If you provide a callback to espeak_Synth(), it will be called repeatedly with as many samples as you defined in the buffer size. It doesn’t matter how long the text is that you want synthesized, it will fill the buffer and return it to you immediately. This allows for a consistent low latency from the moment you call espeak_Synth(), until you could start playing audio.
  2. eSpeak supports events. If you use a callback, you get access to a list of events that provide a timestamp in the audio, and the type of event that occurs there, such as word or sentence boundaries.

And, of course, with all the recent-ish platform improvements above, I was really time for a fresh attempt.

Future Work
  • Break up the data files. Right now, eSpeak.js is over a 2MB download. That’s because I packaged all the eSpeak data files indiscriminately. There may be a few bits that are redundant. On the flip side you get all 99 voice/language combinations (that’s a good deal for 2MB, eh?). It would be cool to break it up to a few data files and allow the developer to choose which voices to bundle or, even better, just grab them on demand.
  • Make a demo of the speech events. It makes my head hurt to think about how to do something compelling. But it is a neat feature that should somehow be shown.
  • ScriptProcessorNode is apparently deprecated. This is going to need to be ported to an AudioWorker once that is widely implemented.

I’m done apologizing, here is the demo.

Mike Hommey: Announcing git-cinnabar 0.2.1

wo, 15/04/2015 - 04:20

Git-cinnabar is a git remote helper to interact with mercurial repositories. It allows to clone, pull and push from/to mercurial remote repositories, using git.

Get it on github.

What’s new since 0.2.0?

Not much, but this felt important enough to warrant a release, even though the issue has been there since before 0.1.0:

Mercurial can be slower when cloning or pulling a list of “heads” that contain non-topological heads. On repositories like the mercurial repository, it’s not so much of a big deal, taking 7s instead of 4s. But on big repositories like mozilla-central, it’s taking 23 minutes instead of 2 minutes and 20s (on my machine). And that’s with 100% CPU use on the server side.

The problem is that mozilla-central recently merged some old closed heads, such that it now has branch heads that aren’t topological heads. Git-cinnabar, until this release, would request those branch heads, leading the server to use the slow path mentioned above. This release works around the issue.

It also fixes an issue pushing to a remote empty mercurial repository.

Mike Hommey: Getting ready for GCC 5.1

wo, 15/04/2015 - 03:59

Confusingly, GCC has a new, weird, version scheme. The first release of GCC 5 will be 5.1. It is due soon (next week). For that reason, and because it’s better to find compiler bugs before it’s released, I started looking into building Firefox with it.

The first round of builds I did was with 5-20150405. That got me to find a small bunch of issues:

So that got me to do a second round with the first 5.1 RC, which had the fix for that ICE.

With all the above fixed, I could finally get builds out of try, and tests running, which revealed two more issues:

  • Another (quickly fixed) Internal Compiler Error on 32-bits PGO builds (but only for a nightly setup, with --enable-profiling, not for a release setup, which doesn’t have it).
  • JS engine assertions during some JIT tests on 64-bits builds (with or without PGO), which Dan Gohman kindly tracked down and reduced to a small test case allowing to file a GCC bug and bisect to pinpoint at the GCC upstream commit that broke it (yay git bisect run on a 36-CPU EC2 instance).

Preliminary results are promising, with benchmarks improving up to 16%, but the comparison wasn’t entirely fair, because they compared GCC 4.8 builds with frame pointers and JS engine diagnostics to GCC 5.1 builds without.

I’ll also give a spin to LTO, possibly finding more GCC bugs in the process.

Anthony Hughes: Report on Recognition

di, 14/04/2015 - 22:47

Earlier this year I embarked on a journey to investigate how we could improve participation in the Mozilla QA community. I was growing concerned that we were failing in one key component of a vibrant community: recognition.

Before I could began, I needed to better understand Mozilla QA’s recognition story. To this end I published a survey to get anonymous feedback and today, I’d like to share some of that feedback.

Profile of Participants

The first question I asked was intended to profile the respondents in terms of how long they’d been involved with Mozilla and whether they were still contributing.

recognition-activityThis revealed that we have a larger proportion of contributors who’ve been involved for more than a couple of years. I think what this indicates we need to be doing a better job of developing long-term relationships with new contributors.

recognition-teamsWhen asked which projects contributors identified with, 100% of respondents identified as being volunteers with the Firefox QA team. The remaining teams breakdown fairly evenly between 11% and 33%. I think this indicates most people are contributing to more than one team, and that teams at the lower end of the scale have an excellent opportunity for growth.

Recognizing Recognition

The rest of the questions were focused more on evaluating the forms of recognition we’ve employed in the past.


When looking at how we’ve recognized contributors it’s good to see that everyone is being recognized in some form or another, in many cases receiving multiple forms of recognition. However I suspect the results are somewhat skewed (ie. people who haven’t been recognized are probably long gone and did not respond to the survey). In spite of that, it appears that seemingly simple things, like being thanked in a meeting, are well below what I’d expect to see.

recognition-likelihoodWhen looking at the impact of being recognized, it seems that more people found recognition to be nice but not necessarily a motivation for continuing to contribute. 44% found recognition to be either ineffective or very ineffective while 33% found it to be either effective or very effective. This could point to a couple of different factors, either our forms of recognition are not compelling or people are motivated by the work itself. I don’t have a good answer here so it’s probably worth following up.

What did we learn?

After all said and done, here is what I learned from doing this survey.

1. We need to be focused on building long-term relationships. Helping people through their first year and making sure people don’t get lost long-term.

2. Most people are contributing to multiple projects. We should have a framework in place that facilitates contribution (and recognition of contribution) across QA. Teams with less participation can then scale more quickly.

4. We need to be more proactive in our recognition, especially in its simplest form. There is literally no excuse for not thanking someone for work done.

5. People like to be thanked for their work but it isn’t necessarily a definitive motivator for participation. We need to learn more about what drives individuals and make sure we provide them whatever they need to stay motivated.

6. Recognition is not as well “baked-in” to QA as it is with other teams — we should work with these teams to improve recognition within QA and across Mozilla.

7. Contributors find testing to be difficult due to inadequate description of how to test. In some cases, people spend considerable amounts of time and energy figuring out what and how to test, presenting a huge hurdle to newcomers in particular. We should make sure contribution opportunities are clearly documented so that anyone can get involved.

8. We should be engaging with Mozilla Reps to build a better, more regional network of QA contributors, beginning with giving local leaders the opportunity to lead.

Next Steps

In closing, I’d like to thank everyone who took the time to share their feedback. The survey remains open if you missed the opportunity. I’m hoping this blog post will help kickstart a conversation about improving recognition of contributions to Mozilla QA. In particular, making progress toward solving some of the lessons learned.

As always, I welcome comments and questions. Feel free to leave a comment below.

Yunier José Sosa Vázquez: Firefox impedirá que recopilen nuestra información

di, 14/04/2015 - 19:21

Si de protección a la privacidad se habla, tenemos que reconocer los esfuerzos que realiza Mozilla para mantenernos seguros en este mundo donde todos quieren espiarnos y robar nuestra información a cualquier costo. Por esa razón, Mozilla recibió el premio a la compañía más confiable en Internet.

Firefox ya incluye la funcionalidad No rastrear, que le indica a los sitios web que no monitorizen tu actividad web, las compañías no están obligadas a hacerle caso. Sin embargo, Mozilla no se detiene y en la próxima versión de Firefox introducirá un nuevo filtro de seguridad que ya podemos activar de forma manual.

Antes de seguir, es importante que conozcan ¿qué es el rastreo en línea u online? El rastreo online consiste en la recopilación de los datos de navegación de una persona a través de los diferentes sitios web; esta recopilación se hace, por lo general, solo con ver el contenido de un sitio web. Los dominios rastreadores solo intentan identificar a una persona a través del uso de cookies o mediante la utilización de otras tecnologías, como por ejemplo, la huella digital.

Pero ¿qué solución ofrece Mozilla? La protección de rastreo te permite tomar el control de tu privacidad. Aunque Firefox proporciona  La Protección de rastreo de Firefox te devuelve de nuevo el control de tu privacidad, bloqueando activamente los dominios y sitios web que son conocidos por rastrear a sus visitantes.

La lista negra inicial utilizada por la herramienta Protección de rastreo, está basada en la lista negra de Disconnect. Si deseas probar esta funcionalidad, debes instalar la versión Nightly que se encuentra en nuestra zona de Descargas para tu sistema, ¿Cómo activar la Protección de rastreo?
  1. En la barra de direcciones, escribe about:config y pulsa IntroRetorno.
    • El aviso de about:config “¡Zona hostil para manazas!” o “¡Esto puede cancelar su garantía!” puede aparecer. Haz clic en ¡Tendré cuidado, lo prometo! o ¡Seré cuidadoso, lo prometo!, para continuar.
  2. Busca privacy.trackingprotection.enabled.
  3. Haz doble clic en privacy.trackingprotection.enabled para cambiar su valor a true.

Esto activará la Protección de rastreo. Si más tarde quieres desactivarla, repite los pasos anteriores para cambiar el valor a false.

Cómo usar la Protección de rastreo

Una vez activada la Protección de rastreo, verás un escudo en la barra de direcciones cuando Firefox esté bloqueando el rastreo desde ese dominio o desde contenido mixto.


Para desactivar la Protección de rastreo en un sitio web en particular, simplemente haz clic en el icono del escudo y selecciona “Desactivar protección para este sitio”. Una vez que la Protección de rastreo se desactiva en un sitio web, podrás ver un escudo con una cruz roja. Puedes volver a activar la Protección de rastreo en ese sitio web volviendo a hacer clic en el escudo y seleccionando “Activar protección”.


Para ver qué recursos están siendo bloqueados, abre la consola web y busca en los mensajes que están en la pestaña Seguridad.

Si deseas probar esta funcionalidad, debes instalar la versión Nightly que se encuentra en nuestra zona de Descargas para tu sistema,

Input finally shrunk, though this is probably due to switching from the South migration system to the Django 1.7 migration system and in the process of doing that ditching most of our old migration code.

Contributor stats

L Guruprasad worked through 16 bugs this quarter--that's awesome!

Adam worked on the Thank You page overhaul. It's not quite done, but it's in a good place--I'll be finishing up that work in 2015q2.

Ricky finisedh up the Django 1.7 update just in time for Django 1.8 to be released. In doing that work, we cleaned up a lot of code, shed a bunch of dependencies and are in a much better place in regards to technical debt. Yay!

Thank you to everyone who contributed!


Django 1.7 upgrade: We upgraded to Django 1.7. That's a big deal since Django 1.8 was just released so Django 1.6 isn't supported anymore. Django 1.7 has a new migration system, so there was a lot of work required to upgrade Input.

Heartbeat v2: We did most of Heartbeat v2 in 2014q4, however it didn't really launch until 2015q1. We did a bunch of work to tweak things for the release.

Alerts v1: We added an Alerts API. Input collects a variety of feedback-type data. After several discussions, we decided that it was a better idea to have alert systems live outside of Input, but push alert events to Input. This allows us to develope alert emitting systems faster because they're outside of the Input development process. Further, it relaxes implementation details. The Alerts API has GET and POST abilities and lets us capture and report on arbitrary alert events.

Alerts API.

Remote troubleshooting data capture: We finished this work in 2015q1. It's now rolled out for specific products and in all locales.

Remote troubleshooting data capture project plan.

12 Factor App: At some point, we're going to move Input to AWS. In the process of doing that, we're going to change how Input is configured and deployed and switch to a 12-factor-app-friendly model. I spent a good portion this quarter cleaning things up and redoing configuration so it's more 12-factor-app-compliant.

There's still some work to do, but it'll be easier to do as we're in the process of switching to AWS and know more about how the infrastructure is going to be structured.

12 Factor App.
