Wayland 1.5 Released

renoX Re:Will it really go the pulseaudio way? (179 comments)

> RDP protocol support was merged into Wayland over a year ago.

That's incorrect: RDP support was merged into **Weston** if you use another Wayland compositor it may have or not RDP support..

I agree with your point about XWayland: as long as the toolkits doesn't remove support for X, Wayland's remote display capabilities can only be superior or equal to those of X.
Now, the tough question is: how long will the toolkits keep the X support?
The developers of desktop tech have been called CADT among other things..

Enlightenment E19 To Have Full Wayland Support

renoX It's about Weston, E19 has its own compositor.. (140 comments)

I'm glad you posted this, but note that the tittle of the article is wrong: the RDP backend was merged into the *Weston* compositor not into the Wayland protocol.

Which means that if you're using E19's own Wayland compositor then of course you **don't** have access to this this RDP backend, unless there is a way to stack compositors?

Interview: Ask Theo de Raadt What You Will

renoX Programming langage (290 comments)

On one hand OpenBSD is focused on security, on the other hand it use a lot of 'unsafe' programming languages (for example C) where security is only achieved thanks to expert programmers, but even experts have bad days and make mistakes..

Wouldn't it make sense to push the usage of programming language which provide more security by default?
For example, encouraging developers to use Ada instead of C..

Google To Replace GTK+ With Its Own Aura In Chrome

renoX Re:Just for a browser? (240 comments)

I agree with you but not for the same reason: my reason is a variant on 'cannot get the basics right': Chrome is not pleasant to use at all on a 4GB RAM PC, it use too much memory which make the PC swap..

I used to prefer Chrome to Firefox, due to its snapiness, good separation between tab, but when it used frequently so much memory as to make the PC swap, I switched back to Firefox.

Larry Page and Sergey Brin Are Lousy Coders

renoX Re:Ideas vs. Implementation (204 comments)

> I never used Wave, and it was shut down long before I joined Google, so I have no idea what you're talking about, much less who made that decision. It doesn't sound like the sort of decision made by a CEO, however.

Wave had a synchronous mode (like IRC) but users viewed all the characters you typed instead of every line or having a 'Send' button: this is a really stupid design decision for two reasons: 1) it use lots of bandwith 2) think if you were discussing with your boss how much you'd *hate* this feature.

As for this kind of decision is made by a CEO or not, I'd answer: it depends. If the CEO is Steve Jobs he would have made this decision (and perhaps fired the one who chose this design) if the CEO is the typical CEO, yes you're right.

Gravity: Can Film Ever Get the Science Right?

renoX Depends (438 comments)

I remember watching stargate (the movie): they send a robot which sends a beacon signal through a warp gate and then they immediately receive a signal saying that the robot is 10 light-years away, instead of having to wait 10 years..

Even though I didn't care about 'scientific realism' in the movie, my brain told me 'this is wrong' and it "took me out" of the movie, so scientific realism isn't a big issue unless it kills your enjoyement of the movie..

GNOME 3.10 Is Now Properly Supported On Wayland

renoX Re:Yes, X12 might have been better (128 comments)

>[cut] with a minimum use of Xrender to stitch them together.

Which is a very good way to use XRender: use the glyph cache in the server for efficient text rendering, for the background render locally and push the pixmap (which could be easily compressed in case of WAN access) to the server and stich everything together.
And you can't do this with Wayland (no drawing API..).

>Even by Qt4.5, they found out that their pure software backend (Raster) was fast than the XRender one (Native).

The benchmark you've linked is a local benchmark, irrelevant for network rendering.

GNOME 3.10 Is Now Properly Supported On Wayland

renoX Re:Yes, X12 might have been better (128 comments)

> - XRender allows you to do a lot of things "efficiently" but we can do them more efficiently with direct or client side rendering and just push a shared memory buffer to the server.

More efficiently? Only locally, remotely it depends on a lot of things (bandwith, latency).

> Qt5 will not use XRender.

I'm not so sure: this webpage list XRender http://qt-project.org/doc/qt-5.0/qtdoc/requirements-x11.html

GNOME 3.10 Is Now Properly Supported On Wayland

renoX Re:Yes, X12 might have been better (128 comments)

> unless you're satisfied with simply calling the Wayland protocol "X12" and be done with it.

You cannot call Wayland X12: X is a drawing protocol, Wayland isn't: it only provides buffers.

And I disagree that an X12 protocol 'woud look awfully like Wayland':
-with X you know where your pixels are going on the screen, with Wayland you don't!
-with X (XRender), to draw text efficiently you can have a glyph cache managed by the X server, with Wayland you cannot have this.

Intel, Red Hat Working On Enabling Wayland Support In GNOME

renoX Desktop interoperability? (168 comments)

On X, you can have a Gnome application running on KDE and vice versa, will this also be the case when the desktops will use Wayland?
Or do you have to use XWayland to ensure that this interoperability still works?

Apple Unveils iPhone 5C, iPhone 5S

renoX Re:Reviving the bit wars? (773 comments)

> Instead it has twice the number of general purpose registers (31) with twice the size (64 bit) than that of the previous ARMv7 architecture.
Increasing the number of register really helped the x86 because it had so few to begin with, for the ARM the effect will be much less important, it'll help mostly floating point processing code.

> and also saves a bit on memory accesses, which are horribly slow.
This depends on what you're doing, going from 32bit to 64bit can also mean that the memory used by your pointers is multiplied by two, reducing the caches efficiency and increasing the number of main memory(slow) accesses..

Hardly Anyone Is Buying 'Smart Guns'

renoX Re:heuristics (814 comments)

>False positive = you die

Well with regular guns, you die too in this case with a far higher probability!

>False negative = you die

Only in the case that firing the gun will save you but threatening someone with a gun (which looks to be functional even if it isn't) won't.
Possible but far from 100% of the case.

GNOME Aiming For Full Wayland Support by Spring 2014

renoX Re:Wayland still alive? (300 comments)

> - What about client application that freeze: Can't move the window because the decoration is done by the client?

I'm not sure about your other points but this one isn't a real issue:
1) Weston the "toy" display server which is designed with CSD ping the client and take over the window in this case.
2) KWin devs plans to use server side decoration over Wayland: Wayland doesn't require CSD.

GNOME Aiming For Full Wayland Support by Spring 2014

renoX Re:It's ironic... (300 comments)

>Except if you have very little bandwidth it is absolutely horrible

Some applications like viewing remotely video needs a lot of bandwidth, there's no way around that, so they don't matter for 'remote display'.
*But* there a lot of applications which can be displayed remotely with very little bandwith as they mainly display text.
With NX/X11/XRender, one can efficiently remotely display those kind of applications, with Wayland there are talks about compressing the buffer delta between a proxy-server and a remote server, it sounds that this would use a lot of CPU and adds latency, but we'll have to wait for the real implementation (if it ever happen) before being able to do a real comparison.
There could be uncompressed remote access also, but it may not be very good in a WAN..

Japan Plans to Restart Most of Their Nuclear Reactors

renoX Re:Foolspeak (255 comments)

> Nuclear reactors represent astonishing amounts of wealth and coordination. It is a hallmark of advanced nations that such things are created.

Except for one "little detail": creating nuclears reactors are one piece of a chain: mining ore, refining, disposing of the combustible and disassembling the nuclear reactor itself.
And in France, *we haven't dissambled our unused nuclear reactors*.
So I wouldn't call this a success .. for now!
