We Win

Mozilla has been making a big effort in the past few years to make privacy and data (ab)use a first-class concern in the public consciousness. I think we can safely say that when a staid company like Barclays Bank is using dancing vegetables on national broadcast TV in a privacy-focussed advert, we have won that battle…

Mozilla All Hands

Today, from across the world, Mozillians are gathering in San Francisco for our six-monthly All Hands. For obvious reasons, I won’t be able to be there, so I want to wish all the best to everyone, and I am confident that more awesome ideas for rocking the free web will emerge from their deliberations. Each year brings different grey clouds to the sky, and requires us to adjust our strategy and tactics to deal with new threats. Some we win and a few we lose, but it’s clear that the world and the web are much better places with Mozilla in them fighting for what is right.

A Case for the Total Abolition of Software Patents

A little while back, I wrote a piece outlining the case for the total abolition (or non-introduction) of software patents, as seen through the lens of “promoting innovation”. Few of the arguments are new, but the “Narrow Road to Patent Goodness” presentation of the information is quite novel as far as I know, and may form a good basis for anyone trying to explain all the possible problems with software (or other) patents.

You can find it on my website.

In the Navel of the Moon

Question: which country’s name translates literally as “In the Navel of the Moon”?

I recently came across this fascinating map which gives the literal translation of every country name. Some are very pedestrian, but some are fascinating. (I’m not sure why it’s on a site dedicated to comparing credit cards, but other places I’ve found it give them the credit. If this is an SEO thing, I’m happy to reward them for producing decent content…) Most appropriately, Canada apparently means “The Village”…

Eurovision Bingo (yet again)

Some people say that all Eurovision songs are the same. That’s probably not quite true, but there is perhaps a hint of truth in the suggestion that some themes tend to recur from year to year. Hence, I thought, Eurovision Bingo.

I wrote some code to analyse a directory full of lyrics, normally those from the previous year of the competition, and work out the frequency of occurrence of each word. It will then generate Bingo cards, with sets of words of different levels of commonness. You can then use them to play Bingo while watching this year’s competition (which is on Saturday).

There’s a Github repo, or if you want to go straight to pre-generated cards for this year, they are here.

Here’s a sample card from the 2014 lyrics:

fell cause rising gonna rain
world believe dancing hold once
every mean LOVE something chance
hey show or passed say
because light hard home heart

Have fun :-)

Fractional Desktop Scaling

In my last computer upgrade, I went from a Lenovo X240 (screen resolution: 1366×768 on a 12.5″ display) to an X1 Carbon 4th Gen (screen resolution: 2560×1440 on a 14″ display). As it turns out, at its native resolution the Ubuntu Unity desktop on the X1 Carbon is simply too small to read. This wasn’t a problem until recently as I did most of my computing with an external monitor. But now I find getting up 2 flights of stairs difficult, I’m doing a lot more using the built-in panel, and experiencing this issue. Fortunately, X11 as shipped in Ubuntu 16.04 LTS has some sort of support for desktop scaling. Unfortunately, it’s a bit rudimentary. I use a scaling of 1.38, but still find that some dialogs look shonky and I have to do extra adjustment for some apps. But it’s just about workable.

I am considering an upgrade to Ubuntu 18.04 LTS where, famously, they have switched from Unity back to GNOME. GNOME does not support fractional scaling with X11 – you can only scale in whole numbers. It does do it with Wayland, experimentally, but Ubuntu decided (after giving it a go in the test releases) not to make Wayland the default for 18.04. I’d like to try this out, but the instructions I found online to do so don’t work with the LiveUSB version – so I’d have to take the plunge before being able to even try it.

So it seems I get the choice of 1x (everything too small) or 2x (everything too big). This is a significant loss of functionality; the X1 Carbon comes with screen options of 2560×1440 and 1920×1080, and it perversely makes me think I would have been better off getting the one with the lower resolution screen! As it is, using 2x gives an effective resolution of 1280×720, which is lower than the resolution of the X240 I used to use. The loss of vertical height is a particular pain point.

Can any reader of my blog suggest a way to solve or mitigate this problem? Is there a “compact” theme for GNOME that still looks like Unity? Are there ways of setting particular apps, like Firefox, Thunderbird or LibreOffice, to use less space or have a default zoom?

Coffin Fits

One fairly common need when someone dies is a coffin. There are various sorts on the market, from bamboo eco-coffins to embarrassingly-tasteless photo wraparounds to heavy walnut ones with carved panelling, which seems rather overkill for something which is to be observed once and then buried underground. I was discussing this with my father when he remembered that he actually has several sets of what are called coffin “blanks” stored away in a roof space. A coffin blank is basically an uncustomised coffin – the top and bottom are full size, waiting to be cut to fit, and the set includes the necessary extra pieces (sides and trim) to make it up.

When the local joiner in our home village retired 15+ years ago (and the jobs of joiner and undertaker were the same job for many centuries) he had several sets of blanks spare, and my father obtained these from him and stored them. They are made of elm, which is a traditional material for coffins but is now almost never used since Dutch Elm disease devastated the British population of elm trees in the 70s and 80s.

We found a joiner here in Loughborough with experience of making up coffins (although he says this is the first time he’s been commissioned to do one by the eventual occupant!). We had the blanks shipped to him, and I sent him my height and shoulder width. On Wednesday, we went to view the result. Elm is rather a “wibbly” wood, as can be seen from the first photo below, which means it’s relatively hard to work but also means it has lovely grains which come up beautifully when polished. Without further ado:

We’re very pleased with the results – it’s a lovely job.

Eggshells and Frailty

In the past seven years or so I’ve got into creating decorated blown eggs, first with a traditional Ukranian wax-resist method called Pysanka, and later with an EggBot. It takes a few hours to do a pysanka so, since starting a family, finding enough time is difficult, but Easter is often both an appropriate moment and a period with enough space. Last year I taught William (then 5) and this year I’ve taught John (now 5). Here are the results from this weekend:

John’s is on the left, then William’s, then mine. I pencil out the designs on the eggs for them, in William’s case according to his specification, and then they try and follow them with the heated wax pen (called a kistka), with varying levels of dexterity and success. Still, even a shaky hand produces quite beautiful results, I think.

One thing which appeals to me about this art is that it produces artifacts which are both beautiful and very fragile – like human beings. Paul writes, using a similar analogy: “But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us.” The treasure is the gospel, and we are the jars of clay – weak vessels who can do nothing by themselves but can, with God’s help, nevertheless powerfully shine God’s light into the world.

Recently, I was reading a sermon on death by Charles Spurgeon, a noted 19th century London preacher, sent to me by a friend. I’ve not read much or any of his work before; he is certainly a man who can turn a phrase. His text was: “The last enemy to be destroyed is death“. As I increasingly bump into reminders of my own fragility and frailty, and know that my own encounter with it is not so far away, is was good to be reminded that for those with the hope of eternal life, our attitude to death is entirely transformed. The second verse of a famous Easter hymn, which I hope to have sung at my burial, sums it up well:

Lo, Jesus meets us,
Risen from the tomb;
Lovingly he greets us,
Scatters fear and gloom;
Let the Church with gladness
Hymns of triumph sing,
For her Lord now liveth,
Death hath lost its sting.

Thine be the glory,
Risen, conquering Son;
Endless is the victory
Thou o’er death hast won!

Spurgeon comments:

And since that memorable victory, every day Christ is overcoming death, for He gives His Spirit to His saints and having that Spirit within them they meet the last enemy without alarm. Often they confront him with songs. Perhaps more frequently they face him with calm countenance and fall asleep with peace. I will not fear you, death, why should I? You look like a dragon, but your sting is gone! Your teeth are broken, oh old lion, why should I fear you? I know you are no more able to destroy me, but you are sent as a messenger to conduct me to the golden gate wherein I shall enter and see my Saviour’s unveiled face forever!

Happy Birthday, Mozilla

Mozilla is 20 today. Most of what can be said about that has been ably said by others, some of whom have been involved for even longer than the 18 years I managed. Asa and I started at roughly the same time, but at least Mitchell, Myk and dmose have been around longer and are still involved. (Apologies if I’ve forgotten someone.)

As most of you know, I probably won’t be around to see much more of it, but (this will seem trite if it’s not to seem big-headed!) Mozilla is much more than one or even a few people. There will always be a Mozilla as long as there is an Internet and people who care about people on it. In that vein, let me also say that I’m absolutely delighted with the final outcome of the worldview project. The four items in the addendum to the Manifesto are admirable goals to aim for, and ones I endorse wholeheartedly.

Lunar Construction

A thought: the moon has water ice and a dusty surface (regolith). Could you use a material akin to Pykrete (a composite of ice and wood pulp about as strong as concrete, and stable at -15C) to create building blocks for lunar habitations in lava tubes, where the temperature is stable and at the correct range for the Pykrete-alike to also be stable (-20C)? Making it would be trivial and only involve raw materials which were present – melt water in lunar daytime, add dust and stir, freeze it at lunar night into whatever shape you want. Even if the habitat were built from blocks, it could be made airtight by spraying the inside with pure water to create a further thin and complete layer of ice. Or, you could just inflate something inside it.

Poetic License

I found this when going through old documents. It looks like I wrote it and never posted it. Perhaps I didn’t consider it finished at the time. But looking at it now, I think it’s good enough to share. It’s a redrafting of the BSD licence, in poetic form. Maybe I had plans to do other licences one day; I can’t remember.

I’ve interleaved it with the original license text so you can see how true, or otherwise, I’ve been to it. Enjoy :-)

Feeling Fraudulent

I sometimes feel a bit like a fraud.

Some of the time – when I climb stairs, or get into a coughing fit which takes 5 minutes to recover from, or can’t eat – it’s clear that I’m not well. But at the right time of day with the right pills, I can sit in a chair and chat to a friend and feel entirely normal. And so when my wife fetches me a drink from the kitchen, or someone else hastens to answer the door, I feel I want to say “No, please, I can do that for myself.” When I ordered a blue badge (a marker for your car allowing you to use disabled parking spaces), I felt that there must be many who are more deserving of one than I am.

But these feelings of wellness and fitness are really an illusion. Normality already includes having to deal with bouts of severe coughing, tiredness requiring multiple naps per day, back pain, and shortness of breath. And, while various symptoms have come and gone (I had oedema in my legs, then didn’t, and now do again but less strongly) the general trend is clear if you look dispassionately. The fact that I can have short periods where none of the symptoms are bothersome doesn’t mean they aren’t there. So why is my heart so keen to believe that the feelings of wellness are real?

As God would have it, we had a sermon today at The Crowded House, Loughborough (on Romans 3:27-31) which touched on this. The root of these desires is the sin of pride. I want to feel independent, in control, autonomous, competent, normal. That makes me feel good. But God has made us to be dependent beings – primarily on him but also on each other – and to find our contentment in him, not in our health or strength. And it seems he is teaching me to depend on him more, both by having to pray for the strength to make it through each day, but also having to graciously accept the fact that I am ever more dependent on others.

In a verse which has been important to me ever since I was diagnosed 18 years ago, God promises that in all things he will “work for the good of those who love him, who have been called according to his purpose” (Romans 8:28). In other words, I have cancer for my own good. Here is yet another way, the latest in a line of many, where God is demonstrating that he is using it to make me, slowly and sometimes painfully, more like Christ, for his glory.

To Planet Mozilla Readers

This is a quick note addressed to those reading this blog via a subscription to Planet Mozilla. Following my stepping back from the Mozilla project, posts to this blog are unlikely to feature Mozilla-related content in the future, and will instead be about, well, what it’s like to be dying :-) I therefore won’t be syndicating them. If you wish to keep reading what I write, you may want to take a direct subscription. Here’s my direct feed.

Going Home

I’m going home.

As some of my readers will know, my cancer (read that link if the fact I have cancer is new to you) has been causing difficulty in my liver this year, and recently we had a meeting with my consultant to plot a way forward. He said that recent scans had shown an increased growth rate of some tumours (including the liver one), and that has overwhelmed my body’s ability to cope with the changes cancer brings. The last two months have seen various new symptoms and a reasonably rapid decline in my general health. The next two months will be more of the same unless something is done.

After some unsuccessful procedures on my liver over the course of this year, the last option is radiotherapy to try and shrink the problem tumour; we are investigating that this week. But even if that succeeds, the improvement will be relatively short-lived – perhaps 3-6 months – as the regrowth rate will be faster. If radiotherapy is not feasible or doesn’t work, the timelines are rather shorter than that. My death is not imminent, but either way I am unlikely to see out 2018. In all this, my wife, my children and I are confident that God is in charge and his purposes are good, and we can trust him and not be afraid of what is coming. We don’t know what the future holds for each of us, but he does.

We’ve taken this news as a sign to make some significant changes. The most relevant to readers of this blog is that I am stepping away from Mozilla so I can spend more time focussed on the most important things – my relationships with Jesus, and with my family. I love my work, and God has blessed my time at Mozilla and enabled me to do much which I think have been good for the Internet and the world. However, there are things in life which are much more important, and it’s now time for others to take up those projects and causes and carry them into the future. I have every confidence in my colleagues and fellow Mozillians that this will be done with the greatest care and skill. The CA program, MOSS, and Mozilla’s policy work are all in very good hands.

If you pray, please pray that we would make wise decisions about what to do when, and that we would live through this process in a way that brings glory to Jesus.

In case it’s of interest, we have set up a read-only mailing list which people can join to keep informed about what is going on, and to hear a bit about how we are handling this and what we would like prayer for. You can subscribe to the list using that link, if you have a Google account. If you don’t you can still join by emailing lightandmomentary+subscribe@googlegroups.com.

“Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.” — 2 Cor 4:16-18.

If I have done anything good in 18 years at Mozilla, may God get all the glory.

Talk Scheduling At Conferences

I’m at FOSDEM this weekend; it’s a large conference. They seem to find one or two new rooms to use every year, and it now sprawls across most of the ULB campus in Brussels.

It has rather surprised me that several otherwise experienced and excellent devroom organizers (naming no names) have organized their rooms on the mistaken belief that switching between speakers, and having people exit and enter the room, happens instantaneously. It doesn’t.

If you schedule your talks in 25 or 55 minute slots (including Q&A) instead of 30 or 60 minute slots, you benefit yourselves, your audiences, and the whole conference in the following ways:

  • Attendees don’t feel they have to leave the talk in your room before the end in order to be sure of catching the beginning of the next talk somewhere else, thereby disrupting the talk, missing the last bits of content (perhaps the all-important summary) and missing the chance to thank the speaker.
  • Attendees can enter and leave the room without feeling they are being rushed or have to be totally silent. (“Please be quiet while entering and leaving/during the Q&A” really doesn’t work.)
  • Room organizers have time to encourage people to move to the middle, or other compression strategies, and pack their rooms for maximum benefit.
  • Whoever is helping you with audio-visual can switch over laptops and get microphones moved over without disrupting the end of the previous talk or making the next speaker start late.
  • Attendees released from your room do not turn up at a different room 5 minutes after the start, thereby disrupting their talks. Love your neighbour.

If you don’t do this, and schedule in 30 minute slots, what happens is that people actually still get 25 minutes or less to speak, as changeovers still have to happen, but the speaker ends up starting late, rushed and grumpy and no-one really knows when they need to finish. 30 minute slots are an illusion. 10 minute/5 minute/2 minute/Time’s Up! cards are a very useful addition to this system, so the speaker knows exactly where they are. If they don’t finish in time and have to be cut off, then they need to be gently encouraged to prepare better next time.

It may be that 5 minutes is not long enough for people to get from one side of the conference campus to the other, and so the issues are not totally suppressed. But there’s only so much you can do, and giving people 5 minutes is much better than giving them 0 minutes.
