@hbdgaf m?

ok

hbdgaf

@Mateo - ping me when you're around, want to see if you're interested in giving something a test drive at various stages of completion

Mateo

@hbdgaf hi, what's up.

I'm almost done with my bluetooth script, just trying to let it do more than one device at a time, which seems crazy for a shell script...

hbdgaf

Working on a hexedit widget for pygi. Wanted to see if you felt like testing to see if it works on Kubuntu when I have it at - just a hex viewer and hex editor stages. It comes in a handy example scaffold, but the use of the widget is obvious.

Mateo

sure, send me a link when you're at that point, I should be free most saturday.

hbdgaf

bleh... that moment when you meant to pick up your monster energy drink and you picked up your beer instead. i just got photobombed in my mouth

@Mateo kthx

Nathan Osman

3:01 AM

All done - I'm registered for SIGGRAPH 2014.

hbdgaf

@NathanOsman you going to try and win an oculus dev kit?

Nathan Osman

IIRC, Pixar is releasing a free non-commercial edition of RenderMan there.

But an Oculus dev. kit would be awesome too :)

hbdgaf

I was just looking at the page and saw a contest. Thought I would ask if you were going for it, or more there to see and observe

Nathan Osman

More to see and observe.

They always have some absolutely incredible tech on display.

I was there in 2011 when 3D printing was starting to catch on.

I was also at the official release of OpenGL 4.2 and ended up with a free t-shirt to commemorate the occasion :)

hbdgaf

Yes. Conferences always have really neat niche tech. I was at a party at ToorCon and some fellow was trying to pitch me on a really well designed ARM board to control door locks. Over-current protection and loss of power protection(minimal, but fail secure after a unlock/relock operation).

Part of the pitch was that it was sort of both fail-safe and fail-secure after a fashion, which was really neat.

Nathan Osman

3:18 AM

Cool.

hbdgaf

Thinking about trying out i3wm. The more I look in to it, the more it looks like fun to use. Working on anything interesting?

heh, yeah. I can even remember the music on my head

Nathan Osman

Lucio

amazing

Go for it! :P

hbdgaf

@NathanOsman Good luck. I'm sure you'll be fine. I'ld rather get better with python and stuff it wraps than try to get mediocre at another language.

Seth

@NathanOsman The game?

hbdgaf

4:41 AM

Oh... yes disambiguate please.

Nathan Osman

@Seth No, the programming language.

Lucio

btw, do you know something about DB recovery nathan?

Nathan Osman

Afraid not.

And if I did - it would be with PostgreSQL, not MySQL sadly.

I avoid MySQL like the plague these days.

Lucio

:(

yeah I imagined so

not only mysql, but mysql v5.0 here :'(

Seth

@NathanOsman Ah.

hbdgaf

4:45 AM

@Lucio superuser indicates you can just copy specific files out, create a new empty database, stop the service, copy the similarly named files back in, set appropriate permissions, fire it back up and hope... but i've never tried it.

Lucio

lets try it

50 tables.. this is going to be a loooong night

nop, did not worked

@hbdgaf thanks for the look anyway

ok, horrible day today

hbdgaf

5:00 AM

sorry. just went to the googles, not the secret NSA broken ex-filtrated tables recovery manual. <-- maybe some humor will make it less horrible

@Lucio how so... it was the start of what i hope is a productive 3 day weekend for me, so i have the emotional stamina to listen about how horrible your day might have been

Lucio

@hbdgaf haha, that made me giggle

@hbdgaf thanks, but I prefer to sleep before boring a friend

Nathan Osman

Go is so weird.

hbdgaf

@NathanOsman I've heard it makes a lot of sense once you get your head around it, but it's really different.

Nathan Osman

I really really like Python.

Python make sense.

Lucio

I only know that Go devs are weird

hbdgaf

5:05 AM

(✿ ♥‿♥)~Python

@Lucio weird is often an indicator of well above average intelligence though.

Lucio

yep, they are also smart

Before I go, my two cents:

Python is Now the Most Popular Introductory Teaching Language at Top U.S. Universities (look at the chinese face and you will believe it)

breach.cc

bye

hbdgaf

I knew that already and neat. I don't think python should be relegated to "introductory languages" though. It just makes SO MUCH SENSE that even many more experienced people like it ;")

Nathan Osman

@Lucio Hey, that looks neat.

hbdgaf

Grrrr. I finally have widget sizing based on Mono-characters worked out completely, then it throws me the curveball of the boxy numbery characters not being the same fixed font width. Need to filter those to periods, but I have no idea how to do that beyond opening the font and looking to see what isn't in there and replacing it with periods...

boxy numbery characters being the appropriate technical term

hbdgaf

6:35 AM

Great, now I just have to figure out using text tags to generate white-space separation for bytes and words. Almost done with the widget.

hbdgaf

6:52 AM

Also fixed the leading zeros and no \x00 showing up bug. So, just left-margin attribute finding in texttags now. >.>

@CarlosAndrésD'Agostino - I've seen you in here a couple of times today, but you never say anything. What's up?

hi @hbdgaf , awake - check. coffee - check

hbdgaf

Coffee is a must have.

Mateo

4:22 PM

@hbdgaf so, cool. your project worked out of box on my kubuntu 14.04.

hbdgaf

@Mateo Nice. I was hoping the sizing would hold.

I don't think I could make the code much easier to read either...

Mateo

hbdgaf

Aah, that extra bit of bar on the right is for people that don't have the unity/kde mini-sliders and still have regular scrollbars. It's not that noticeable though

Mateo

@hbdgaf hm, resizing the window dosn't change the contents

hbdgaf

Nope. It's statically sized. Most hex editors are that way.

It's so you keep row dword alignment or whatever

Mateo

4:25 PM

@hbdgaf dosn't look bad - maybe go back to the grey to show the column stops

hbdgaf

If I tried to make it not do that, you'ld wind up with weird offsets on the left. Yeah, that's a possible. When I did that I thought it was a little ugly. It's worth thinking about though.

It would be a less than one-line change. Switch the "expanding spacer textview" back to a box instead.

Mateo

hm, maybe if it was as easy a specifying a background...

@hbdgaf oh so the last ~~box~~ widget just expands

hbdgaf

there's an extra empty ~~box~~ widget over there that just expands to fill, so the others don't distort

hbdgaf

@Mateo even if you could, it's a single transparent pixel. and no, i don't notice the redraw.

Mateo

sweet

hbdgaf

it's super-kludgy, but i'm still putting it on github. that's three different projects/goals in a day and a half.

Mateo

I got my bluetooth script to a point - a point where I started wondering why I was using a script ;) so if I want anymore than two devices at once, I need to switch tactics. github.com/mateosalta/BLARG

hbdgaf

4:40 PM

@Mateo I'm not sure why you'ld want to do that, but as long as it's working for you.

@Mateo Think I should package the chromium workaround as an app and throw it in ppa, so other people don't get as irritated as I did and hack something together?

Mateo

yeah, just making it hard on myself... I was thinking it would just wait till one was done, then the next person could donload, kept thinking I wanted at least two people to connect at the same time

hbdgaf

Yeah, you need an on-pair callback and subprocesses or threads.

Mateo

@hbdgaf maybe, it is simple - and no visual glitch

hbdgaf

Crud... I have to take it out of tab switching though. >.> what was that function/api

Mateo

It's good the actual bluetooth-sendto is a GUI - I think it is also built-in to select the free adapter so they can be launched and run independently. the big problem was it kept detecting the transfer as a connection and re-sending to the same device

hbdgaf

4:51 PM

if not device_dict[device].is_sending(): device_dict[device] = True; device.send(something)

Mateo

yeah, I need to see if any of the tools can tell me if it connected or sending

although, with sending to bluetooth you get a message on android first to accept the transfer...

so kindof a limbo... don't want to resend, but not sending

hbdgaf

once you enter the try to send branch, even if you're not sending, you're sending. might be a way to check if the send completes or fails though

also, the show/hide was too fast. it only worked sometimes. added a delay. now there is a flicker, but it works consistently.

it has to be slow enough that chromium realizes part of its window is hidden and redraws everything but that one pixel, then redraws again when that pixel is revealed.

and now the kludge is on github github.com/aking1012/chromiumKludge

Mateo

5:17 PM

ah, so I'm telling it not to connect to the first if it is open, I just need to have it ignore the number of connections based on how many are open

then get a bunch of adapters and phones together, to see if it actually works...

hbdgaf

can one adapter send to more than one device at a time? i don't know that

my solution would be populate a dict or list of devices with attributes on "is_sending". once you pair and try to send, consider it sending even if the client refuses. they can always repair to get another crack at it.

Mateo

hm, I assumed it is was one adapter - one send. but the send to program may be able to prioritize?

hbdgaf

i would assume an adapter could send to more than one. consider using a bluetooth mouse, keyboard, and earpiece. you have to be able to send to more than one at once.

grant they don't need feedback much, but one would think it would be built that way.

Mateo

must be, not sure how many

hbdgaf

'A master Bluetooth device can communicate with a maximum of seven devices in a piconet (an ad-hoc computer network using Bluetooth technology), though not all devices reach this maximum. The devices can switch roles, by agreement, and the slave can become the master (for example, a headset initiating a connection to a phone will necessarily begin as master, as initiator of the connection; but may subsequently prefer to be slave).' from wikipedia

Mateo

5:22 PM

@hbdgaf yeah, once it finishes or refused it terminates the connection - they need to try to connect again to get back on the list

@hbdgaf woah, so I really don't need to worry about getting another adapter

hbdgaf

you could forcibly drop the pairing after sending is tried. then they might autopair. if you could track bytes sent, you could tell if it actually went or not and start ignoring devices.

Mateo

my first version was based on paired or not - unfortunately dropping the pair on the computer end confused android - it thought it was still paired, and errored on the next two attempts to pair

hbdgaf

there has to be a reset code you can send

Mateo

not to mention populating my network connections with multiples of "Nexus 5" from all the pairs...

but that is a Ubuntu(or whatever handles the network connections) bug ;)

hbdgaf

I keep bluetooth disabled... so I don't have any kludge for that one ;)

Mateo

5:29 PM

yeah, I like the simple file transfer option - but it should have the option to not try list everything as possible tethering for internet...

hbdgaf

It could be worse, they could just disable send-to-bluetooth like apple did. Solve the hand grasping problem by cutting off your arm is how I see that crap.

Mateo

@hbdgaf true, well looks like I'm reading more man pages ;)

hbdgaf

@Mateo have fun with it. i've been reading API introspection for half of the last 36 hours. people really google too much and don't use dir() enough. the thing i'm working on blows my mind every time i work on it, but if i ever get it to the starting line, it will totally be worth it.

wow, just read this as a limitation in a manual for bluetooth: "Note that when a dongle is removed from the system, the radio will lose power(assuming this is a bus-powered device). This means that devices will lose connection."

hbdgaf

orly? whoulda thunk it

@jokerdino so you're working on something that could replace trello or you're using trello on some project?

hey guys

hbdgaf

sup chaskes

i've been having a gangbusters weekend over on github. mostly simple stuff, but lots of little wins.

chaskes

cool

Braiam

@hbdgaf starting a headache...

chaskes

@Braiam I confirmed (it's in the wiki, don't know how I missed it before) that when installing debian you either have to reformat the swap drive or set it to not use it. No other choices.

hbdgaf

8:20 PM

@Braiam if i don't have one, i consider myself to be having a top of the day morning.

@chaskes if you set it to not use it, that's no biggie, you can just add it to fstab and swapon later.

hibernate gets wooly with shared swap though

chaskes

@hbdgaf that's what I've taken to doing, but it's just a small pain, and you should have the option to use without formatting.

Braiam

@hbdgaf well, my first headache was at 19 and wasn't even a hangover, so I get pretty irritable when I get one... I'm just not used to having one

chaskes

I don't use hibernate, but that's a good point

hbdgaf

@Braiam mine aren't hangovers. it sounds like caffeine dep, but i tried substituting caffeine tablets and that didn't work. so it's something else in the coffee.

chaskes

too much caffeine, too much ibuprofen, etc cause rebound headaches when you don't take it

hbdgaf

8:24 PM

i never take ibuprofen, and supplementing with caffeine pills didn't work... so i'm at a loss.

chaskes

weather changes, pollen, hard cheese...and staring at computer screens are the next big culprits

hbdgaf

eyestrain might be it, but it happens whether i do that or not.

moving on... three mini-projects in a day and a half feels like a win.

Braiam

the usual culprit for me is lack of sleep...

chaskes

@Braiam even you young folk need sleep ;)

Lucio

Braiam

8:50 PM

@hbdgaf I saw a bug in debian bug tracker

Lucio

I just noted that you are playing with chrom* on github

hbdgaf

well it's a thing. the window only partially redraws on switching. i came up with a kludgy script to fix the issue without touching chromium github.com/aking1012/chromiumKludge/blob/master/kludge.py

Seth

@hbdgaf I can understand that, yes.

Braiam

@Lucio both comes hand on hand... nobody understand that

Seth

@Lucio Review audits aren't about improving statistics though.

chaskes

How about Spanish as a 2nd language... I'm having lunch in pollo brasero yesterday when all of a sudden I understood the name of the cd-writing program.

Lucio

8:58 PM

@Braiam yeah, but you can still have good statistics killing community

Braiam

@Lucio what really kills the community is the bad quality content

hbdgaf

Heh, for me it would be spanish as a third language although i haven't used the second in years

Lucio

@chaskes lol

@Braiam you will have bad quality content destroying the review tool

Seth

@Braiam That's... not really true, necessarily.

hbdgaf

I'm not in this one, but I can say I can see both sides of the thing.

Braiam

9:00 PM

@Lucio that the community upvotes offtopic questions is outside of our control... which means that the community really don't understand quality

close and delete this one askubuntu.com/q/249898/169736

is actually a hardware problem

why nobody deletes the freeze tag if they are VtCing?

no repro askubuntu.com/q/431098/169736

@Seth good hard data and general impressions are equally important for the healthy development of a community

Seth

9:16 PM

@Braiam not sure what you mean there. All I was saying is if you're brutal about stats it won't necessarily improve your community. Actually, from my experience, it is more likely to do the opposite.

Braiam

@Seth I'm saying that both are important, if you focus in only one aspect is very likely you will fail

bug askubuntu.com/q/312438/169736

Seth

@Braiam If you focus on building a good community the chances that your stats will go up naturally are good, but if you just focus on increasing your stats the chances that your community will improve aren't as good. Perhaps 50/50. My take anyway.
