socles updated for jogamp 2

Just to show that it's not all angry rants around here ...

Continuing my mirror of the news items on my projects, I just updated socles to include jogamp 2.0 - fortunately the API was the same so it was just changing the included libraries in the build.

I still have a JOAL patch outstanding but just haven't been in the right mood to work on it for a while. Getting back to work last week was a bit of a shock to the system; but i'm slowly getting back into the groove and will eventually have time and energy left over for hacking.

I've been doing a bit of video stuff which is helping to harden and clean up jjmpeg a bit more, and I have a few minor patches pending for that. I've also been poking very tenatively at a slideshow creator/video compositor: but there's a lot of crap I don't really want to have to write (ugh, timeline anyone) so i'm not exactly making any headway yet.

WTF Google?

I noticed google search becoming less and less useful of late: it can be quite hard to track down meaningful results, and I started to suspect I was getting my own private view of the internets ... (which is precisely the thing I do not want from a global internet search!!).

So with in that mind check these two results out, one from my signed in google account - with verbatim enabled, and one from another machine in which I'm not signed explicitly into google's world-encompassing spy network.

Standard results:


Verbatim results:



(I also checked the non-verbatim results on my logged in version, which are at least in this case thankfully the same as the standard result; although i'm sure i've seen differences in the past).

One might note that the verbatim result is the only one that has anything related directly to the search terms, particularly for the most important keyword of high specificity - there is in fact no relevant result AT ALL on the first page of the non-verbatim search (as suggested by the title and/or preview content). I really don't think a generic '[Archive]' header applied to old mailing list views should rank highly.

The new search algorithm is quite good at finding home pages for projects and products; but for specific information it's starting to suck major arse.

At least verbatim taught me this isn't quite the search term i'm after anyway.

Cantarell Sucks

Why any designer with any mote of sense would choose Cantarell as a font is beyond me, let alone a system-wide default one. I know it was trendy - nearly 30 fucking years ago - to create a distinctively unique system font; but that was mostly about cost anyway and now there are plenty of decent free fonts available using a number of common formats.

When I re-installed my workstation with a minimal fedora 15, Cantarell was about the only font that came along for the ride by the time I had XFCE up. Which made for a particularly unpleasant experience in Terminal and emacs - until I installed xterm and 'fixed'. Apart from being a disastrously ugly and unreadable font; it decided to use the proportional one as well; so it didn't even work.

Apart from many of the letter forms being simply ugly and out of balance, the kerning and hinting is abysmal (although TBH I think hinting has more than had its day, and we're better off with blurry aa text, even on screens 1024 pixels wide). It is just one fugly font and the only reason I can see that anyone would like it is that their favourite hero endorsed it and the group-think around the hero's heroish aura is suppressing their mind's own ability to reason. I suppose having someone working on free software as a hero is better than worshipping some money grubbing greedy pig-fucker like the late Jobs, or Gates (however, being a brainless sheep is nothing to be proud of); although those money grubbing greedy pig-fucker's are often the inspiration in the first place. Not a fan of the ubuntu font either; which again seems to gain its popularity solely from celebrity endorsement.

(As an aside: people seem to be trained more and more these days not to think. Not to make a stir. To go along with the crowd. Even the wild frontier of the internets has been tamed, flame-wars seem to be banned from most forums and minority views are blatantly suppressed as a matter of open forum policing. As if suppressing and censoring dissenting views somehow makes them go away or is a valid long-term solution ...).

So ... although i've resolved not to go whine on other people's personal blogs (it's like going into someone's house and abusing them), i let my guard slip a bit this morning and posted a long dissenting (but mostly polite) view on a post about GNOME. I really wanted to sleep in but was awake before 6, so I wasn't in the best mood.

Anyway, it ties in with my last rant about 'tabbed desktop'; some of the suggestions are just stupid. Most of the suggestions are just a straight-up rip-off of an iphone, and then the group-think fanbois have the audacity to turn around and accuse people of stifling experimentation if they don't like it or don't think they'll work on a desktop computer? Nothing innovative or experimental about copying an apple interface (which seems to have been the sole `raison d'être' for GNOME ever since Apple's Mac OSX came out). The thought that one application can cater to every possible device is as inane as it is nonsensical. Even less so is the suggestion that one stern style guide can cope with every possible application and user class ...

I'm not sure why I even care; I haven't even used GNOME for years, I didn't even start using GNOME for years even when I was working on GNOME software (iirc until Novell bought ximian and I dropped RedHat 9 and amiwm for development ...); so I never really liked it. I thought gnome2 was bloated, slow, ugly and too limited so my less-than-gold standard of GNOME goodness pre-dates even that.

However, now I think about it, I know why I care: I know how this shit works. It becomes trendy and then everyone starts doing it and suddenly there's no-where else to go and you've got some fugly font installed by default. Or systemd, or networkmanager, or pulseaudio. Thankfully the font is easy to fix and pulse audio is easy to blacklist (although yum seems to ignore that sometimes), and networkmanager easy enough to bin as well. But it still makes it more difficult to get a working system set up every time and there's always a chance some snot like systemd (whose whole purpose seems to be to enable gui tools to poke into areas they shouldn't be involved with in the first place) which weaves itself so tightly into the system it simply cannot be removed.

(Aside again: It would help if systemd wasn't written by an author who clearly doesn't have a clue with system software, and adding such a complex and horribly nasty implementation behind it. And it would help if fedora didn't let pricks like this bully their way into such a core system service as init.)

The counter-argument is that it must be a good idea if it's popular and people are using it ... which if course is crap. We all saw how microsoft illegally forced its crapware onto everyone; popularity is not a technical metric, it's a political one. And people are easily manipulated, particularly if they're proud of their inability to think independently.

Although there's one thing that the GNOME developers and I agree on, even if they might not admit it: hacking is fun, and users suck. I wouldn't want to listen to whiney know-it-all's either. Then again, i'm not working on anything that the public relies on for their day to day computing experience ...

I just wish i'd had a good night's sleep now. Headed for an unpleasantly hot (39) and unpleasantly windy (30km/hr+) day today, i'm too tired to think about hacking, bored with tv, movies, and games, and my eyes are really tired from reading the screen too much this week; best hope is to water the garden a bit and maybe have a nap later followed by a couple of cold beers.

Scene Graphs

So, today is my weekly RDO and rather than spending it down the beach like I should have, I poked around ...

I was thinking of experimenting with a scene-graph model for GadgetZ (used in ReaderZ); not for any particularly practical reason, just to see how it would work. But I kind of got stuck on how to manage the layout mechanism and then lost interest ... still a bit burnt out from my hacking spree a few weeks ago, and I need a good sleep-in one day to catch up on sleep as well (they're still building next door).

I did however end up spending quite a bit of time playing with the JavaFX stuff. The 32-bit-only build wasn't too much hassle to get up and running on Fedora. It has some (pretty big) issues with focus, and the performance ranges from awesome to barely ok, but it is only a developer preview after-all.

Some observations:

• The rendering model looks very interesting. Obviously the aim is to provide a fully accelerated zoomable interface via the scene-graph. This is obviously absolutely the right thing to do.
  
• And for the most part this works well: it's very snappy when it's snappy.
  
• It tries to sync the rendering to the display and double-buffer rendering.
  
• The WebView thing looks pretty decent - it's a whole webkit binding, with dom access and the plan is to move to a JVM based javascript eventually.
  

Some issues though:

• No printing yet.
  
• Performance degrades fairly significantly when a lot of data is present. e.g. in the JavaFX Ensemble demo opening view - trying to scroll list of sample icons.
  
• The vsync doesn't work very well, lots of glitches (but i blame this mostly on both pc hardware and linux: even a commodore 64 had hardware well beyond a pc video card for smooth animation).
  
• Things like scrolling the WebView is flicker-free, but not as high a frame-rate as i'd expect for hardware rendering. But I don't know if it's delegating rendering to webkit as I do with PDFZ.
  
• The documentation needs work.
  

I'm not about to use it for anything; i'm not even going to bother to try for that matter, but I'll be keeping an eye on it. It seems to finally heading in the direction it initially promised after JavaFX 2 was announced: a high performance modern toolkit with a clean simple(ish) design, media support, and so on. Simple enough to use as a RAD tool, but complete enough to write real applications as well.

It seems as though Java8 will have something to look forward to for once ...

I'm also curious to see how the JVM based JavaScript engine will work; the JVM is fast, but I suspect the language will some bearing on achievable performance as well.

(i've nothing to comment on regards the hope to use it as a flash replacement for internet deployment, i'm just considering it as a desktop application development platform).

Flash: good bye and good riddance

Hmmm, so the news of the day is that Adobe are dropping flash support for GNU/linux. Oh praise the day it finally goes away for everyone ...

One can speculate on why, and why they're only `supporting Google':

• Adobe are in the creation-tool business, why are they wasting so much resources on maintaining a crapply plugin they give away for free? i.e. there are compelling business reasons to kill it entirely.
  
• More and more internet-enabled devices are unable or unwilling to support it; without the ubiquity of client access there is little reason to use it. This is also why silvelight will never be more than a niche. I don't see the point of JavaFX either unless it is available for free on all devices fast enough to run it (it going GPL shows clearly that Oracle know this too; they can't afford to maintain it for all platforms, and nobody would ever pay to license it - and even then in the end it'll probably just be a swing replacement for desktop development).
  
• Paying clients are willing to prop up the legacy technology for the time being, so Adobe don't want to kill the whole project off. Pissing off paying customers isn't a long-term bread-winner.
  
• Most of these paying clients do not care about GNU/Linux enough to keep it around there.
  
• Google are willing to fund a partial solution: as a marketing exercise in order to move people to their application platform (otherwise known as a 'browser'). It's just a cynical exercise to gain market share.
  
• It's basically 'the world' vs firefox. Proprietary companies want more control of the web pie, and will work together against firefox any way they can. e.g. see the HTML5 video drm proposal, the fuck-up with H.264 HTML5 vs OGG video, and so on.

Overall this isn't such a bad thing: even if it is just at the periphery, fewer projects will consider using this legacy technology. Already with Apple not allowing flash on their web-enabled mobile devices they have destined it to become history. Without its cross-platform ability it loses its main feature. It's just shit tech anyway; flash struggles doing much on my dual-core low-res thinkpad; it will be a while before ARM chips match that (ok, maybe 12 months in consumer devices), but the machine is fast enough to run other software quite well.

However, everyone seems to think HTML5 will be the answer. I think it will be a horrible mess harking back to the bad old days of netscape and microsoft extensions. Already most of the HTML5 demo's only work on one browser, or even a specific browser version. Most HTML5 video is in H.264 format: i.e. inaccessible from firefox by default. And you can't simply 'flash-block' a javascript animation: leading to an annoying browsing experience and a lot of wasted power animating web pages you're not even looking at.

I find it odd that HTML5 is being pushed so heavily: on the apple iphone you can't really do much more with it than simple games or animations. You can't even upload a file from a web-page (as far as i can tell), and device access is right out. To me the impression is that all the marketing hype is just FUD to get people from spending time on competing technology.

Some of the tech demo's are all very nice and all: but web software is still much shittier than a local application for interactivity and control, not to mention security. It's like using AMOS: it might be a lot easier to write a game, but you still end up with a shitty game. Down the track it's obviously aiming to be a 'be-all-end-all' RAD application development environment that makes writing simple applications easy; thing is, simple applications are already quite simple to write, and complex applications are always going to be complex to write. Adding the web tier adds a lot of complexity in itself.

Complexity is not your friend

The complexity of standard like HTML5 isn't there to benefit users or developers. It is added to benefit proprietary vendors and stifle competition by raising the barrier of entry to new competitors. And of course lawyers and other parasites end up getting a cut as well: the complexity is so great vendors must cross-license software in order to be able to get something working. That's even before you add issues like patents into the mix, which is just insanity.

HTML is already so complex that creating a fully compliant implementation is only possible by large multi-national corporations; and opera and mozilla. HTML5 only raises the bar higher and that's before you add all the proprietary extensions to the standard which are already proliferating.

Goodbye Freedoms

HTML5 applications will also be much harder to modify and control; even if the source is available, it may be impossible to create a local copy that works without the infrastructure on the server-side used to support it.

Thus forget about distributing and sharing your changes with other users, or hiring a third party to make a customisation tailored to your business.

Welcome to the Tabbed Desktop

So we're all moving toward a tabbed desktop. i.e. who needs multitasking when you can just swap applications at the press of a key ... Well, microsoft windows and the apple macintosh pretty much forced this from the start because their systems were so poor at multitasking; but real systems have been able to utilise multiple overlapping windows in a way which improves user productivity for decades.

But it seems we're going back to the full-screen application model. Except now the applications are running in a crappy single-threaded virtual machine and being loaded remotely.

Hang on, I think thats 80's calling ... they're asking how that WIMP thing worked out ...

Early morning drowsy mistakes

Oops, so yesterday morning I went to replace a dead HDD and re-install the OS on it. I thought I was being careful and unplugged the other, working HDD with a different OS on it so when I came to partition the disks I just deleted everything (the replacement disk had previously had CentOS on it).

Only i'd unplugged the wrong one, and ended up deleting the working OS and not the spare drive i'd just installed! Unfortunately that OS's installation partitioning tool writes every change immediately, so it was all gone even though I realised before i'd moved to the next screen. The installation disk for that OS is pretty crap too - it kept refusing to install on the disk I just formatted using the installer: it took a couple of resets before it was happy with it's own formatting ...

I tried recovering the partitions using testdisk, but either because of the filesystem types or the partition layout I had no luck with that. Just an hour down the drain waiting for it to scan the 1TB drive.

Fortunately I had made a full backup, so I lost nothing apart from half a day re-installing everything.

This time I installed Fedora 15 using the 'minimal install' option; and apart from some strange package selections (e.g. ssh client isn't installed, but server is), it actually took me a lot less time getting a comfortable and working system than it did when I just let it install GNOME and then had to remove all the crap (pussaudio, notworkmanager, and similar crud). What is also strange? It boots, logs in, and runs much faster than it did the day before. And now Thunar opens immediately the first time rather than pausing for a few seconds.

I had some weirdness with systemd and it not starting X after I installed it - which seems to be much more fucked and complex than I could possibly have imagined - but that just magically fixed itself after enough reboots. Also with thunar's auto-mounting stuff, which I think I fixed by installing gvfs, but it might've just been enough reboots too ...

Dishwasher

So the dishwasher that came with the house finally died: I've hardly ever used it. It's been flakey for ages and I've mostly been waiting for it to die so I can replace it with one that cleans properly and uses less water so I can actually use the thing. Not that I would even bother with a dishwasher myself if it wasn't there, but well i'm getting lazy and the rest of the house seems to waste a lot of water doing dishes. It washes glasses well too.

I think it's only a solenoid gone; if I add water into the sump it pumps it down the drain so the pump works. Or maybe it's the logic board: it runs for half an hour with no water in it and sits there blinking at me.

Ahh decisions. I spent hours very late last night (for some reason I wasn't tired), trying to work out what to get. Money isn't an issue: but I don't like getting ripped off either. I've a Miele washing machine and plenty of people swear by those for dishwashers too but they do seem a bit pricey. But then there's Asko and Bosch too ...

I'm thinking the latest Asko at the moment, but I guess I should try and find somewhere that sells most of them so I can have a look. Unfortunately the big-box retailers are miles away and mostly in people-unfriendly strip-malls; or they're so fucked I'll never return to them (Radio Rentals, Main North Road: unfriendly shop design, with one-way doors and no staff, Spartan Electrical, Henly Beach Road: fuckwit salesman when I was after a stick blender I knew I could get $15 cheaper 5 minutes away by bicycle).

So it could be a long purchasing cycle: waiting until I could be bothered to make the long trek to a shop, hoping they have the ones i'm interested to look at, and putting up with being treated like shit by salesmen who will say anything to sell. Or getting fed up and going on-line again with a sight-unseen buy.

Hmm, maybe i'll poke around the back of the one I have ...

Update: Well the back-look was worth it. Apart from finding the remains of a mouse and nest - which explains at least one of the weird smells in the kitchen over the years - I gave up and shoved it all back together (in a rather slap-shod not-caring kind of way so now the door's a bit stiff). And now it's taking in water ok, will have to see how the full load of glasses and jars I wanted to clean goes. Either I jolted something in the process or it was just the act of re-seating the solenoid connector ...

Update: Ahh fuck it, it wasn't that: it just keeps puming for 10 minutes after the initial spray, and eventually times out. Water sensor must be out. Something for another day.
