Speech Transcript - Lightning talks

0:00:10	okay thank you can be and
0:00:14	so i was quite surprised i was trying some people that you know some project
0:00:19	i was working on a mentioned i maintained is attacked the other day and you
0:00:22	know half the people in the group actually said i use easy tag i didn't
0:00:26	realise use the maintainer so who is the information of what is it's an audio
0:00:31	file tag like you know when used to get your M P three files medically
0:00:36	server and used to be able crappy with attacks and everything is something where you
0:00:40	can tell you about it's really all application of the specimen in two thousand we
0:00:45	display one buys you room for the and he to get job maintain until two
0:00:52	thousand may well
0:00:54	he became you know a lot of other things to do an didn't really do
0:00:58	much of that time there there's can see which is you know but also patches
0:01:02	lots and lots of uses quite surprising you know "'cause" moderate which you are anything
0:01:07	that he didn't keep it in a version control system there was no get business
0:01:11	up version that wasn't even C V S it was just travels that he dumped
0:01:14	every now and again
0:01:16	based on source forge side awkward to contribute to not really a nice bike track
0:01:20	are also stuff
0:01:23	so some of the people you know use this and actually fill that help out
0:01:27	it was kind of rejuvenated a little bit and late two thousand and ten that
0:01:31	was a republican get have some good patches played in that work and distributions of
0:01:35	things
0:01:36	and that was a release also wasn't very much you know few patches here and
0:01:42	that nothing major
0:01:45	that was some good discussions so the main this someone can abilities case we what
0:01:48	was people asking for that was a mac us export let the good stuff happening
0:01:53	but the maintain is didn't really know much about the project they kind of
0:01:57	can barely make a release they didn't really understand all to do you know it
0:02:01	was it didn't really what
0:02:05	so i came along and so picked up doing the each case people stepped how
0:02:12	old the old stuff you know with stepped out all of the all dependencies so
0:02:16	depend on the latest you to the whole quite a lot tighter but it occurred
0:02:20	your the build system all the horrible and took or that actually patches up really
0:02:25	maintaining for ages match those
0:02:28	and then you release to promote right
0:02:33	alongside make a new release midgets and all because it's wages to contributed and it's
0:02:38	also is in my opinion you know we moved about solar everything so i think
0:02:42	so and they have very for doing a lack and andrei for doing the bugger
0:02:45	stuff segmenting this that's great
0:02:50	got again way will contributions
0:02:52	little patches medicines massive amounts of people looking pretty good i'm menu website the translations
0:03:00	are also like we were really start with translations are really quality ones i had
0:03:04	people you know german guys coming up to me and saying is translations not we
0:03:08	get the name translation guys really high quality translations think very much about
0:03:15	there are a few annoying licensing things like usual event if will be to and
0:03:19	it was a G P L application that in P few and it will be
0:03:23	to is and libraries size that was licensing about that you know so i had
0:03:27	to get rid of that the guy for debian have in the past to get
0:03:30	stripped out and use time and sets of much that it was using
0:03:36	live and you want to three which can potentially decayed mp3 so that wasn't shipment
0:03:39	for dora so we have to get rid of that as well and if you're
0:03:43	bound help with that this is really cool with much total this number support which
0:03:47	was never there before so that's great all the firewire and everything that was horrible
0:03:53	that was using like public stuff and a really nasty way so it's thank you
0:03:57	see file and things how to few summer okay students who are helping to pull
0:04:01	things you see file sort of finally modernising the could a software been so languishing
0:04:05	creators
0:04:07	fixed lies of memory leaks it's now basically valiantly
0:04:11	not quite a but pretty good
0:04:17	current state where we can see a very well still looking let the horrible that's
0:04:21	it still it and finally it is get application i did actually suggest on the
0:04:25	main is that i was gonna make this display three only in take it runs
0:04:29	of lazily features but
0:04:31	they complained
0:04:33	i know that they complain i was easy settings as well i finally convinced people
0:04:37	that maybe it was an okay idea
0:04:39	let's most of planned when this package things been requested a lot
0:04:45	if you wanna help please do and this last think well is very guys that
0:04:49	i already think mostly in the tall and sleeveless
0:05:11	so next ones going to be see change
0:05:13	our about of and boring i think that writing libraries and by that's a good
0:05:17	idea
0:05:23	it's getting better now you just write applications and rather
0:05:28	actually the latest application and or does endorse
0:05:32	hello so what did we do in boxes loans since last year's kodak be introduced
0:05:39	it that was the first product we introduced this project into if you still don't
0:05:42	know what it is contact you know explain everything to you
0:05:46	if i'm in a good mood so what have been doing well relaxing
0:05:53	fishing
0:05:56	well actually mark on the didn't catch any fish in the trip and he looks
0:06:01	pretty system will giving and some more lights
0:06:07	it
0:06:09	that's all
0:06:16	okay now we did some more
0:06:19	actually a lot of our a lot of work went into a lot of hours
0:06:24	fixing all the bugs it's it was a very fragile application glottic at least the
0:06:31	last year but now it's very robust it's very much more efficient there's a lot
0:06:36	of
0:06:36	you know you i fix is the you i didn't look as much like the
0:06:42	you i mock ups as it does now it's a lot more similar and it's
0:06:47	that therefore it's a lot more friendlier and looks much better and as you know
0:06:51	every detail matters
0:06:53	so those bugs and all these stability fixes they were the most important thing and
0:06:58	that's what we concentrated most on
0:07:01	apart from fixes we have some new features to search it what within boxes and
0:07:06	in a shell you're gonna search your ubms the anywhere anytime you want you have
0:07:11	a federal box just right for door and then you hit enter
0:07:15	more customization options these are this is that you are few examples i think there
0:07:20	are some more options we do that too we had to do this since all
0:07:24	the or distillation of us place we didn't and these drivers which means that now
0:07:29	you can have water resolution and when you install the box you just the resolution
0:07:34	changes automatically in the V M and you don't need to do much and copy
0:07:40	and paste between host and yes that's a very useful thing and everybody wants that
0:07:44	so we have that you know out of the box
0:07:49	you have your direction you have a use we device you want to use it
0:07:52	inside your em so we allow that and we have options for that you can
0:07:56	enable individually which devices you want to share with your that actually it's not sharing
0:08:01	but you say that you want the V M to use it rather than the
0:08:05	host and then you can disable for each device separately
0:08:09	smart cards i'm not so familiar with this part because it's comes from a spice
0:08:15	for free for us and there's some particular kind of smart cards that we support
0:08:19	and we don't support all of them marc andre snorting so i guess i'm right
0:08:24	over support re finally have this chris talked was working on it for a lot
0:08:29	and he has is still working on that making improving it a lot and if
0:08:33	you have a all worked up and set up some very or you have access
0:08:36	to it from your work you can now access all your boxes by just giving
0:08:39	the U R L that and you will get older machines
0:08:43	options bosnians more product logos you can see and how it is good is to
0:08:50	our docks team
0:08:53	and i recently also added image import so you have some other okay we hands
0:08:58	where you have an image and you just take that then imported although it in
0:09:02	image doesn't to tell us all the information that we need for a for we
0:09:06	and so it might not work correctly or it might work it's up to the
0:09:11	image like which architecture and all that but we are working more on that and
0:09:16	we'll have support you import and export of ian's from more toolbox and then
0:09:23	member and all these you i so
0:09:26	import or export
0:09:28	so
0:09:30	that's all
0:09:40	thank you jan so next going to be like to make the very long way
0:09:44	from tokyo to run like "'em" to but
0:09:47	but no
0:09:49	as they job he actually works on replacing the pantheon other infant libraries
0:09:55	but he's probably going to talk about something it's
0:10:13	i a sort who mine but we knew this
0:10:18	this talk with the quick up little bit when you get text
0:10:23	as you know get text cz to help real guys programs that's qualisys over two
0:10:31	parts that i read about on to spot and a as a most of people
0:10:39	know it is a really
0:10:41	it has a very long history
0:10:47	in that i ready about it provides basic functions to create straws initials from database
0:10:55	nothing goes get fixed and you get they just you get text
0:11:01	on but
0:11:03	basically and this libraries not the unnecessary or when you linux systems because
0:11:11	those functions a must go into the main when you T V C
0:11:18	and in on the outside that tools a still necessary to
0:11:23	extract transitions from source code and also money be at the database files such as
0:11:30	your files so i'm all right
0:11:37	i as i think you know get text has a baby roman history it has
0:11:43	a beam probe also
0:11:45	eighteen several on
0:11:48	and
0:11:50	it had to be maintained by bring hyper for two areas
0:11:56	and he lastly actually became easy and i happen to take will but maintenance
0:12:04	and there i used to buy shows and
0:12:10	directives buzzer wasn't used or
0:12:14	last months
0:12:16	and it has some with this for
0:12:19	we don't program us
0:12:22	the main improvements well
0:12:26	zero point eighteen point three is new programming grantees sampled it has now sampled for
0:12:33	G D K be the and javascript and the do on about a on the
0:12:38	also it's has sampled for by some three what is the syntax for want a
0:12:44	risk the syntax for want strings sampled
0:12:47	so
0:12:48	here is that example
0:12:53	with our greatest it fixed we chat
0:12:57	real party ski because
0:12:59	confusing steering seen that you know especially there's on the also we can use unique
0:13:07	will escapes
0:13:08	in source code
0:13:13	on
0:13:14	it's also
0:13:15	it's not also sampled bar on so
0:13:20	now we can use smart multi line strings in source code on it can be
0:13:25	extract it into P O files and easy utterance if it
0:13:32	and also it has some portal bichsel so you will not the strings
0:13:38	usually
0:13:40	we use
0:13:42	pretext are formants the rings
0:13:45	for us officials but we can use well the last scene tax all want strings
0:13:52	and
0:13:54	and some
0:13:57	tutors provided by get fixed can chicks
0:14:02	so it has of the
0:14:05	well what the strings
0:14:09	so
0:14:10	we also have save our feast has brand and currently we don't have a sampled
0:14:16	for you called escape scenes see on fire so recently by gets in you go
0:14:23	escapes so we need to out that
0:14:26	on also there are some ideas xing round she's
0:14:31	so
0:14:32	and also we have as a
0:14:39	well closing we don't project
0:14:41	so many other things to do
0:14:45	so socks
0:14:55	i
0:14:57	next going to be in a big from bungalow
0:15:23	everyone minute be drawn and i'm here to talk about using system but manage well
0:15:30	decision
0:15:31	so and not associated system in any way except for being the user but i
0:15:36	really like the massive clean up the system didn't brought to the system itself and
0:15:40	actually users is that
0:15:43	so i mean there's all these features and that's all well documented to be able
0:15:49	to a to know more about if you can look at layers but post about
0:15:52	these i've been talking about
0:15:55	this how we can use these in the users yourself
0:15:59	so now the users itself has that seem requirement as a system you have so
0:16:04	is it starting up i need to manage we had the starting up properly or
0:16:08	what but it's you order there in and are we keeping track of how they
0:16:11	are doing
0:16:12	so you don't like this and so i don't as it
0:16:15	you don and of remote quite a not right what happens is that
0:16:21	this subtle differences between the two mostly because of X but also because of everything
0:16:29	everybody around gnome session and nice decision it's to so the first i'll talk about
0:16:36	a couple of things are different
0:16:38	on one of them is of them and results so we do not for instance
0:16:42	have any pi defines
0:16:44	for the president users that so we can't is that you can decide when of
0:16:49	us so it's a started based upon that be at five if you have it
0:16:55	be the service which likewise i mean on the bus is fine you just wait
0:16:59	for that in your dot but and for a lot of them if you don't
0:17:02	get places it's you use if you have a bit a startup once
0:17:06	and they don't care what that and the minimize obsessively it's fine i mean you
0:17:10	will get some religion or what is what you can eventually
0:17:13	but for some you do get
0:17:15	for also audio forms or and for give us or cell
0:17:21	one of these just you can the others
0:17:23	it's after the next
0:17:25	and so for plus one you and give us once you have a fixed part
0:17:31	you can do is okay recognition and it's not a properly so this is what
0:17:35	are usable socket looks like if you were sort of system be
0:17:38	what for X we have this
0:17:41	and that's dependent upon the display variable we spend the fee vd and that is
0:17:45	to be found over system do before starting X or started by excellent figured out
0:17:50	to do so that's kind of tricky and the way to fix that is by
0:17:53	making excuse also look at inside it wouldn't be a is a but that's like
0:17:58	the previous one
0:17:59	so there's a lot of other problems like this and all and what is working
0:18:02	on that right now i'm here is of figure the stuff out and then you
0:18:06	know more or you don't
0:18:08	that's talk about some of the features which will get for decision once this happens
0:18:15	so first of all this eclipse we get uses control you'll be able to use
0:18:18	firefox and actually got look over in be it's a G five and not have
0:18:22	advisable more usable you have and then you that for five is rebounding your head
0:18:26	wondering what i to don't know life the second thing is weeklies right now we
0:18:32	need have a very limited time and not really a part of your law decision
0:18:36	with this can be able to have
0:18:40	the united G D bus id settings and other things which are part of normal
0:18:44	so works on the media's that you'd have display you that believers available you have
0:18:48	a acquisition available all those things decided i you have session my really bugging so
0:18:53	you can figure out which so this is a starting up which are services are
0:18:57	running right now what has crashed why isn't evolution what can right now all this
0:19:01	distinguishes that right now and you can even figure out it depends a great figure
0:19:05	out which is which is a session with services taking was not and using startup
0:19:09	you login so you will be able to figure that out and will get more
0:19:13	results in getting possible contains
0:19:16	so combined with this and the fact that system the a system that's what recognition
0:19:21	the i'd evacuation laws that by the startup also together we would save up like
0:19:26	these i guess half the time i don't know i don't have to try to
0:19:30	say because it is that you work it
0:19:32	but we'll see how that would be all right and that thank you
0:19:46	thanks
0:19:47	next going to be we actually as
0:19:51	she's I O P B R O P W income prague know aren't venture doesn't
0:19:58	work we're going to norm stuff she designs part process for living
0:20:03	hi i'm a i'm a typeface designer and i'm also it will be W intern
0:20:09	working on norms you i found kinda and even though i'm giving an internal i
0:20:14	think talk tomorrow i thought it would be nice to show you guys some of
0:20:18	the improvements that you can expect in the font in the next couple of months
0:20:22	i will mostly be focusing on the improvements descriptive language support but i thought i'd
0:20:29	so you some general improvements which would make some people happy
0:20:34	so i'm going to the entire had to set of the phones looking at each
0:20:39	and every cliffs and seeing if anything looks bad so in the next couple of
0:20:43	months you can expect most clunky shapes
0:20:47	things which don't look like to look right
0:20:52	i well before i started my internship that a lot of criticism about kind to
0:20:58	those bald we had more particularly the fact that it was much wider than the
0:21:03	regular and it looked in some cases nothing like the regular so there's gonna be
0:21:08	able which is practically brand new it's
0:21:12	narrow it looks much more like
0:21:16	the regular so if you look at the look is give for instance
0:21:19	at the top and the bottom it sort of different because there's a slight space
0:21:22	in the middle which for some reason the original didn't have if you look at
0:21:27	the lowercase E you could see that the first shape is kind of ugly which
0:21:31	is being improved
0:21:34	so there's something like that but more importantly there is gonna be some improvements to
0:21:40	language and script support
0:21:42	well so i think that work with the doing a small sort of V such
0:21:47	projects but i like that
0:21:49	those sort of top sixty of the dot sixty like know how do i see
0:21:54	this all so i looked at how normalising localised and the sixty languages which have
0:22:00	the maximum percentage of localisation already done i sort of sat down and so which
0:22:06	cat it does they are required to be you know used on screen and then
0:22:11	looked at which characters existed in the font and which ones were missing and the
0:22:16	attempt is gonna be to try and add all those characters to the form and
0:22:21	whatever i'm not able to do that i hope to five some extremely detail about
0:22:27	so that leader if someone wants to add let's see vietnamese support you know exactly
0:22:32	which creates they need to add and so there's no sort of you know well
0:22:38	he didn't miss that you want to do vietnamese but you miss five kids
0:22:42	the next thing is much better
0:22:46	of support for extended lot and less
0:22:49	which means that well it soon as i can get an "'cause" working on font
0:22:54	forge there will be a different set of diacritics for uppercase and lowercase letters which
0:23:00	will harmonise much better with them of also you know make sure that the diacritics
0:23:06	are hanging at the like this from the let us so if you look at
0:23:09	the look is are in the before image the palm ability doesn't sit weighted should
0:23:15	so making sure all of that is perfect in all the diacritics actually look nice
0:23:22	the next thing i will work on it is us is really even though can
0:23:29	to data has syria like support its kind of patchy and the quality of lives
0:23:34	at least i felt was really not up to scratch also you see a lot
0:23:39	of that does i mean actually a large part of the characters that has been
0:23:43	completely redrawn to make sure that not only are that lives better looking but there
0:23:49	is better research about what it's cliff should look like
0:23:54	and if all goes well and i worked really hard there should also be greek
0:23:58	supported can to data by the time i finish my internship
0:24:02	and in general i hope that in all the work that i do of that
0:24:07	is a whole lot of research that goes in then the typeface you have in
0:24:10	the end is good so you know if you look at
0:24:14	the latin cyrillic and greek scripts they all look not the similar but there are
0:24:19	the letters onto the identical so you can expect things to be
0:24:24	you know really well researched and make sure that each script looks like the way
0:24:29	it should
0:24:31	so thank you and if you have any ideas any feedback on the front there
0:24:36	is a high fest on monday and i love to hear from you
0:24:49	thanks
0:24:50	so next as don't store could be currently living and we don't know
0:24:54	probably not drawings or string for too much doesn't roll
0:25:00	okay
0:25:05	sorry i'm gonna have a short hard we demo so maybe all people pray to
0:25:09	the hardly calls
0:25:10	for a moment well the get set up
0:25:24	okay
0:25:43	okay hi so i would can vienna is a biologist and we do behavioural experiments
0:25:48	and an important part of doing visual behaviour experiments is understanding and the latency and
0:25:54	the time characteristics of the animals that are on drugs and it is
0:25:59	and so latency is measured in an experiment car contains line see from the display
0:26:06	driver from the windowing system the way that you're rendering and from the hydrant monitor
0:26:13	so
0:26:14	assuming we're running prefix offer an idea stop compute and we can minimise the first
0:26:18	three or to we can we still have the problem of that great variability and
0:26:23	latencies and monitors
0:26:28	so to me show the latency the component of the total latency that was and
0:26:32	you know it by the monitor doing whatever image processing it's doing we created a
0:26:36	simple little hardware widget and some open source software to do that and i would
0:26:43	just trying to do it here but just give me a moment and the motivation
0:26:47	is to it's selfish it's for our purposes because of with building equipment the requires
0:26:52	buying you know twelve monitors we wanna trying by the ones with the lowest latency
0:26:56	that we can
0:26:58	so the point of creating this tool was to create it so others can use
0:27:00	it and they can taste the latency of monitors they are in and by the
0:27:04	way weeks the project is and everything else as well and then hopefully and when
0:27:08	it's finished you can could submit this to some sort of database if you wish
0:27:12	and then way selfishly could query that in by the my monitor with the lowest
0:27:17	latency it's slightly faster than what we currently do which is going in to all
0:27:21	the electronics shops plugging it in measuring the latency ourselves
0:27:47	step because to hardware goals
0:27:50	also unstable upon to
0:27:54	and when was the last time the and you speaker driver crash for anyone that's
0:27:57	you
0:28:00	is be serial port i mean
0:28:04	this one
0:28:08	so when you run the software what you see is basically there's a flashing black
0:28:14	and white our panel at the top so we major black white black transitions all
0:28:18	we use black what like transitions to mission latency
0:28:21	and you simply take your hardware which has a photo diode and some signal processing
0:28:26	running on board and how it up to the screen
0:28:30	and wait a while
0:28:34	if it isn't right
0:28:45	that's fine right
0:28:46	it's
0:28:48	lower level than that
0:28:50	you know a show me come simulators wanna see not grace "'cause" was working twelve
0:28:54	seconds ago
0:28:56	is everything
0:28:58	once again
0:29:08	alright so this is not gonna cooperate but essentially you
0:29:14	you all the sorted right up to the selection panel and you get a single
0:29:18	number latencies timit and we're also recording like the precise shape of the rising and
0:29:23	falling age and so that's kind of useful for us like as well but is
0:29:28	useful to our user and you just get a single latency number might twenty four
0:29:33	milliseconds if you've got a good monitor or forty milliseconds or if you go to
0:29:37	bed monitor so sort interesting if you wanna build one the really simple if you
0:29:41	wanna see it actually work i'm can see me in person but check out the
0:29:45	website thanks a lot
0:29:58	thanks don't for showing as far like the most of that idea
0:30:02	next going to be adam doesn't admit that you were touch upon because it's got
0:30:07	was responsible for the last financial crisis
0:30:10	right so i am item not a typeface designer but i'll show you how to
0:30:16	create a gnome logo font
0:30:19	so what do you need you create unique your logo in this case you can
0:30:24	get stick non look different are grown brenda kind and we decide
0:30:30	you can take it with inks capes or and i did inform forge and directly
0:30:34	after you imported you create your problem that you can then use with your application
0:30:40	of choice and if you want to do some funky stuff then you can also
0:30:44	create a method post version of it that piece do it it's so this is
0:30:50	how it looks like it's one for just a you import your logo and scale
0:30:56	a streak it i just about of the cliff
0:31:01	once we created to have fond you can preview time all different types of points
0:31:06	that we have
0:31:08	but only three lines of code you can exchangeable appliance in your attention process of
0:31:14	your choice
0:31:15	so you have your nice know votes as bullet points you can use it in
0:31:21	deeper office presentation or document and with mid post you can create to funky animations
0:31:31	but counters page count as or just cutouts for example to go for the of
0:31:38	your bitmap picture
0:31:41	and the five sound get top if you have any suggestions improvements just any email
0:31:47	me you can try out the font or just create your own logo font
0:31:52	that's all thanks
0:32:01	thanks adam next going to be mitch is going to freestyle which means those flights
0:32:07	exactly i didn't bother hi i'm i image from to get projects so you have
0:32:11	to listen to me
0:32:12	so the topic of the talk is a how to port the main
0:32:18	image display expose callback from the old to you can wait the to you could
0:32:23	to way to it that you can frame dropping to because we ate
0:32:26	and the underlying problem is that what do you do in your exposed ten term
0:32:30	and you have something to render that is really hard and expensive to produce like
0:32:34	you can possibly do it and every frame so you have a buffer you cash
0:32:38	the stuff that's easy someone's you have to buy for you can displayed instantly but
0:32:42	what do you do if you don't have to buffer yet so if you have
0:32:44	to it suggest to catch problem like
0:32:47	if they say there are only two hard things it's naming and cash innovation at
0:32:51	that disk exactly cash innovation here
0:32:54	so what we did in G T K to risk into we had an idle
0:32:58	callback that would just go over this you which part for that is invalid and
0:33:03	validated rectangle by rectangle and after each rectangle it would just expose it and because
0:33:09	i will hand there was running at a slightly slower priority then the G D
0:33:13	K expo centre this should would automatically regulate itself so after each and if you
0:33:20	would in validation of your you which image cash the expo centre would run one
0:33:24	which just flashed a stuff to screen so and i thought you know that's very
0:33:28	easy so i just go ahead and for this idols thing to adjudicate frame clock
0:33:32	callback very easy super easy trivial tried that
0:33:36	to me about an hour and it worked immediately but at a strange thing that
0:33:42	it just was super slow so if you have an image like this from your
0:33:46	you which digital camera in C D K tool disk into it would like validate
0:33:50	liked this and in C D case read would like
0:33:53	slow and
0:33:56	the fact this year and counting the number of rectangles it was doing and of
0:34:00	course at sixty frames per second i had hundreds of hundreds of rectangles and that's
0:34:05	what was just wondering so what is going on here so i thought sure and
0:34:10	each of these rectangles is validated much a faster than in the sixties of the
0:34:15	second which is
0:34:16	fifty milliseconds or what was it again so something like that so i thought i
0:34:20	just measure the time that i have in one take
0:34:24	and pre calculate how many of my small the rectangles i can render so
0:34:31	and have if you look at the G D K frame plot api it has
0:34:34	a lot of stuff as predicted time and predicted presentation time and whatnot and i
0:34:39	was kind of going mad and consulted on and he together we added like a
0:34:45	ton of print absent a cheetah came in searching for the problem and in the
0:34:50	end it turned on that was all on the completely wrong track because you kind
0:34:53	of possibly expect your expensive
0:34:58	cash construction function to run in the tick callback because the T callback should just
0:35:03	run as fast as possible you have to use the time between the takes
0:35:06	and move your construction load of your
0:35:10	well you cast construction function into the idol
0:35:14	and so i did that so the entire topic i want to talk about is
0:35:17	completely white and would because i'm not using the T callback at all so my
0:35:22	liking talk fails i had to do it differently but i can assure you that
0:35:26	if you have to construct something
0:35:28	expensive don't do it in that a callback do it in the time between the
0:35:32	takes and few and i do that is that the lower priority than she dekai
0:35:35	parody redraw and do it there in small chunks and once
0:35:40	that a callback comes it will flash but you have entered so far so
0:35:45	i think that's about it thanks
0:35:51	thanks
0:35:54	it's going to be that the who is part of the local organising team
0:35:58	that organised this conference so maybe special ploughs we all
0:36:07	thank you so i additionally i know slides but i am we show you some
0:36:12	videos
0:36:14	so let me
0:36:17	should be what the implement data or with the and it you know three point
0:36:23	eight
0:36:24	this part of normal help or non documentation for end users
0:36:29	it this
0:36:32	get it's not the videos
0:36:34	which are made by a cooper steiner and i the actual content or that subtitles
0:36:40	and packages into well known getting started looks package
0:36:43	so this is all ending screen for though for the getting started
0:36:48	videos or tutorial
0:36:50	which you can see a then you of any finish setting up don't know system
0:36:57	if norm initial setup
0:36:59	there's also one in the really over the place
0:37:06	meanwhile
0:37:07	looks like this
0:37:10	you know like this version
0:37:12	this is example of music but well it's muted know
0:37:24	basically shows you have to
0:37:27	an application z-norm shown which is probably
0:37:31	holes interesting topic to users vastly channel from other environments like well like a environments
0:37:43	so going back to this guide we have some pretty probably most important topics you
0:37:48	show
0:37:50	and you click a thumbnail it's place a video in a and i've been the
0:37:54	whole build a video you can see subtitles
0:37:59	i think shoes things that you can see in the video store in the stop
0:38:03	light us build the video or and died in the yelp of in though with
0:38:09	translatable so the external whilst on that
0:38:15	to link we have been known which is ideas tool and
0:38:19	get text
0:38:29	so just a quick look at the markup for the landing page
0:38:34	me be here we imply man dull sorry here we have the thumbnails for videos
0:38:46	hear it can see the subtitles detection was things
0:38:51	we also use not conditionals to show different version to users and running a stand
0:38:58	out know show and users running an show they've got signal the extensions
0:39:06	and all this is in the in the signal single version all the whole of
0:39:11	the package
0:39:18	now let me
0:39:21	show you something for from though i perspective
0:39:26	yes i mention we make use of well implementation of the i yes and that
0:39:35	made by W pretty
0:39:37	see so this implement facials made by shown like hands
0:39:42	for the know but for males but from basically
0:39:46	it allows you to specify context and then so this commands
0:39:52	an actual strings then you need to
0:39:57	i why i would get thanks marching a little stings in different places into single
0:40:04	place no translation file
0:40:07	so for example
0:40:10	in the guide we have a couple of S E G files and chuck will
0:40:15	actually show in the L
0:40:19	for example than on the big problem a lot of pictures basically this is your
0:40:23	final exam take shows things like the activities are the name username and all these
0:40:29	are translatable
0:40:31	because we put them in S P G and make them
0:40:36	and look like not information
0:40:41	so when we have for example be which stands for tuesday and thursday we have
0:40:45	a problem because there is this basis can't translate
0:40:49	it so we implement the will look not at the good you know i'm and
0:40:55	and that way
0:40:57	we can easily made the content
0:41:02	i again friendly so i think that's about it
0:41:07	you
0:41:11	a
0:41:13	next but not last skate to be right talking about it couple editor
0:41:19	break i'm sorry
0:41:22	sorry i'm a plan to still kind of time and the most gonna go for
0:41:25	my that
0:41:51	okay i guess us
0:41:54	so we this is a project i've been working on the last year or so
0:41:59	but sort of part time as ways
0:42:04	i'm a graphics guy and serve kind of what's on kind of all levels of
0:42:08	the start really as ways of work from sort of silicon enabling for G P
0:42:12	A is up to sort of kernel driver development open G L driver better i
0:42:17	three toolkits and windows is and stuff helped us with class a lot and currently
0:42:24	maintain the couple
0:42:26	three gpu graphics api
0:42:30	it is time working on there is you are technologies i've kind of had this
0:42:35	mounting feeling i suppose of
0:42:37	the fact that we tightly waste is really flexible a gpu hardware this in all
0:42:43	of our what about consumer devices finds out tablets and laptop somewhat know and
0:42:50	been wanting to try and see what we can do to try and take a
0:42:54	different approach maybe to take better advantage of the hardware as well is that i've
0:43:00	being for to fortunate enough to work in an office where there are visual design
0:43:06	is colocated with engine is and
0:43:10	seen the process by which
0:43:12	design is come up with their ideas using one set of tools and there is
0:43:17	this big impedance mismatch in translation problem in then communicating well they one and actually
0:43:23	engineering not ring onto a
0:43:26	onto a device
0:43:27	so something i'm really interested in is trying to improve that what fly between design
0:43:33	as an engine is
0:43:35	this is the approach that we basically taking here is to
0:43:40	well we learning a lot on where was stealing ideas basically from the game developers
0:43:45	actually because these guys are facing so many the same issues as you are developers
0:43:49	they do a much better job of using the gpu than compared to you are
0:43:54	design as and so
0:43:58	with building a you why rendering engine essentially which is shared between a visual design
0:44:04	tool and something that's gonna be deployed another vice
0:44:07	and
0:44:08	the actual visual design process is gonna be constrained by the actual capabilities about technology
0:44:17	and it's
0:44:19	so there they can so that what is that you show there is the idea
0:44:24	you can also connect this visual design environment to a device that represents a devices
0:44:30	connected of the network which should be sitting on the desk of the visual designer
0:44:33	while they work and
0:44:36	they connect it and as soon as they make changes to the animations in such
0:44:41	things then they should be have to get immediate feedback by picking up that phone
0:44:45	and actually playing around with the responsiveness and performance of what they're working on because
0:44:51	there's no subsidy for testing your ideas
0:44:55	actually on the hardware that you're intending to deploy your interface on
0:45:00	so we're trying to optimise that whole work flow
0:45:06	right from the very beginning waste are actually prototyping and
0:45:11	so you and as it as it being a kind of game engine approach
0:45:16	we do
0:45:17	for practical reasons have to leverage algorithms and ideas come gently from rendering photo realistic
0:45:24	scene so you'll see that we're using that the field so the things further from
0:45:28	the viewer look softer and we've got shadows here in inside the idea this is
0:45:33	show you have popping up the notifications in the thing this most recent is
0:45:38	most prominently that is clearer
0:45:40	but
0:45:42	that's kind of our practicality because the
0:45:46	researching G P R reasons takes time we have to be extracted so in the
0:45:50	future we were and we'd be interested in researching the non photo realistic stylised the
0:45:56	uses of the G P as well
0:45:58	such as painterly kind of making something that
0:46:01	is painted with an oil
0:46:03	with a little pain so schedule it will go kinds of
0:46:06	interesting things but
0:46:08	basically this gives the tools so this it you would certainly enable you to shoot
0:46:13	yourself in the for in terms of the
0:46:16	pretty horrific design if you tried to you know look like of a and a
0:46:22	massive three D user interface see if you went overboard but i think with the
0:46:27	care
0:46:30	the judgement have a good design i think that
0:46:33	okay so i'm out that but that gives you gives you an idea of what
0:46:37	we're trying it and this is on get up to is ugly up their one
0:46:42	or such reagan or just come an estimate you're interested in
0:46:46	thanks
0:46:53	thanks
0:46:55	next going to be for the recover who no longer has a big idiot page
0:46:59	because he's not can so that significant anymore
0:47:06	it was deleted because
0:47:09	how do according to be a lack of not ability or something more
0:47:13	so
0:47:17	are what can see if the time and this thing works
0:47:22	so
0:47:23	five minutes okay
0:47:25	so these days i am a
0:47:30	can everybody read that
0:47:33	or should i should i make it bigger
0:47:41	is it this they sent me tomboy called change eclipse
0:47:45	sorry
0:47:50	so we just the cost is one of the most important thinkers of the twentieth
0:47:56	century she died in two thousand and six unfortunately
0:47:59	i've been trying to read all of her over
0:48:03	and let me talk a bit about that the first book she wrote children you
0:48:07	got she was born in scranton pennsylvania but she move to new york city up
0:48:12	and she was like a teenager i think the first actually wrote which everyone should
0:48:16	read
0:48:18	what's called a dash
0:48:20	and we life
0:48:23	of grey and marry and
0:48:28	fumbles i mean see peace
0:48:31	that the death and life of great american cities and it's like the first book
0:48:35	on orbit need some
0:48:37	that you should read it's probably the last one you will ever need to read
0:48:41	if you're interested in why C Ts work
0:48:44	why some cities work why some C D's don't buy something surplus into living by
0:48:47	some six or not this is a book you should read people to have who
0:48:51	have been following me it might belong will know that i'm a big fan of
0:48:54	christopher alexander
0:48:56	i hope it's a relax on the road the geometrical mathematical aspects of
0:49:01	well designed places jane jacobs wrote about the social aspects you know what's the purpose
0:49:06	of the sidewalk
0:49:07	it's not just to let you go from the street to the shop on the
0:49:11	other side of the street it lets you keep people safe when people can watch
0:49:16	them at so it's a it's a very interesting book
0:49:19	after this but jane jacobs wrote a few others one a very good one is
0:49:24	called the economy of C D's
0:49:27	well if i keep writing i'm gonna over on my time and the next one
0:49:30	was called economy of C D's
0:49:33	and holding to research on are gonna some topics she started thinking well how com
0:49:41	there are countries right and countries are seat is how come there even though you
0:49:45	might think of a country as rich like the united states
0:49:49	why does the united states have very rich see this and very pour C D's
0:49:54	or any other country you know
0:49:56	so she by at the other ring a lot of evidence like connect that the
0:50:01	latest evidence from newspapers and economical economics papers and this and that she was able
0:50:07	to figure out that
0:50:10	cities that allow for small scale commerce and production to happen in them
0:50:18	are the ones that gets richer over time and i don't just mean reach are
0:50:21	in and in a monetary sense
0:50:24	but also in the sense of people being skilled people being civil to each other
0:50:30	so it's a very interesting book
0:50:32	the next book is called citizen the wealth of nations
0:50:35	and it explores why the traditional ideas from like adam smith and young that john
0:50:43	games or kind of i don't know how to pronounce that
0:50:45	from
0:50:47	why those ideas of macroeconomics don't really work in the real world micron about macroeconomics
0:50:53	as it is this big abstraction that doesn't really working the fine details
0:50:58	so should for that down
0:51:00	and shorten you economic theory based on actual evidence from the real world and it's
0:51:05	basically an expansion of his previous work and it's very interesting many years later
0:51:11	when we had a lot more knowledge about the origins of life and ecology and
0:51:17	biology and this and that
0:51:19	she rewrote air economic theory in terms of
0:51:23	ecological terms what's ecology is the movement of nutrients
0:51:29	in the living world or the movement of nutrients and energy you know and it
0:51:34	turns out that it works exactly the same as economies working see this
0:51:39	amount of time
0:51:41	so you're telling me my phone different role
0:51:45	okay and the one of the other books you wrote this call systems of survival
0:51:50	and is able can reading right now it's about
0:51:54	how come the commercial system
0:51:59	or people who do commerce or production of goods like we do they have a
0:52:02	completely different moral system from governments and guardian type things and it's a very interesting
0:52:08	thing i think this book allows most explain why ugly known got very productive
0:52:14	at some station and right now i think we don't think it is getting a
0:52:17	bit territorial and it should not do that
0:52:20	i think the this because explains that and what i mean
0:52:23	thank you
0:52:57	ran out of juice
0:52:59	so
0:53:01	last for today is going to be and this of course up talking about stuff
0:53:05	that no one of us one street
0:53:07	right
0:53:08	so i see a room full of people who care about their privacy who care
0:53:14	about
0:53:16	service we treat them right and the data ownership but will you actually reads the
0:53:24	terms of service when you sign up for web service
0:53:30	okay really so i wanna talk to you guys because we doing this little project
0:53:36	called the terms of service didn't read because that's what we do read we see
0:53:42	a new service and it online service we signed up for it and there's this
0:53:46	little checkbox i've read and agree to the terms service check it and so not
0:53:50	okay so no one actually reads them which is kind of a problem because what
0:53:56	these terms actually say is most of the times a not what we know what
0:54:00	we like or what we want so this is an initiative to rates or you
0:54:06	read we actually read the terms and then rate them on a and a to
0:54:10	E scale like from green to red
0:54:14	just like the european washing machine label for instance
0:54:19	so we have a browser add on for instance which automatically puts the rating in
0:54:25	the in the browser so we have some we have some ratings already so there
0:54:29	is
0:54:31	i will friends and so let me let me zoom in or something can you
0:54:34	see that okay or
0:54:37	so goal is classy us like average you do this class the other let's see
0:54:43	what youtube is wrong there's lots of thumbs down there so we so we rate
0:54:50	based on paragraph so we so we
0:54:53	or based on sentences are based on specific criteria so data retention for instance or
0:54:59	if they can just delete your account or if when you delete your account they
0:55:03	don't and keep your data
0:55:07	and so for instance you to the copyright license is broader than necessary which might
0:55:14	not be a very good for you if you're if you your you're doing videos
0:55:20	professionally or something a similar thing for five hundred pixels for instance or to fit
0:55:25	pick you probably heard about the what was it the hudson river folder thing where
0:55:32	the hudson river plane crash there was the first folder of it taken was uploaded
0:55:39	to or it was treated i which means it was uploaded with pick and then
0:55:43	to a there was a copyright compared which would take on it so the original
0:55:48	owner didn't on it anymore or the original takers the photo and that's kind of
0:55:55	a problem i think do you agree
0:55:58	that's what i wanna hear okay so yet fit biggest classy it's like the worst
0:56:03	rated so far we have doctor go for instance its class a because it doesn't
0:56:08	have tracking i it's not open source though it's that's also kind of a problem
0:56:12	but that's a different issue
0:56:15	because we thought like there are open source services but these are the service people
0:56:21	use so we need to rate them
0:56:24	and so we have some more there's some which aren't rated yet we have some
0:56:28	points like your face but we have
0:56:32	some data points so
0:56:36	so if it looks like it's gonna be a classy probably also
0:56:40	and
0:56:43	we're very small team only working part time on that we're completely nonprofits we recently
0:56:49	collected donations and are working certainly working on it but we need more especially low
0:56:56	expertise working on that and just people wanna read from the service also you i
0:57:02	guess and you and maybe there was someone who wants to me it's terms i
0:57:07	wanna talk to you and have you on the mailing list and contribute to that
0:57:12	because
0:57:13	we just want to help people who i mean not everyone can read the term
0:57:20	the service it's just like a an unbearable and delusion of text like the right
0:57:25	fun fact the i choose turns service are longer than that so gives you like
0:57:31	an idea of the scale so
0:57:36	so it is the website and i so i really recommend like just installing the
0:57:41	browser add on it will show a rating like the a small i can next
0:57:45	to the next of the thingy next endeavour spar and you will know this is
0:57:49	a class a or D service and you know thank
