shadwolf 14-Jan-2011 [5633] | Pekr linux is fast on boot time i mean a genuine linux ubuntu 10.10 on a 1.6 ghz procesor like my netbook boots up in 30 seconds wich isn't bad at all compare to the 5 minutes of boot time needed to start windows 7 starter ed on same machine... |
Geomol 14-Jan-2011 [5634] | That's how computers should work in general. My new 2.53 GHz MacBook Pro with solid state drive boots in 17 seconds or so. My old iBook G4 boots in 50 seconds. Still my old 50 Mhz 68030 Amiga could boot in less than 10 seconds. |
shadwolf 14-Jan-2011 [5635x9] | then you have chromeOS which boots in 8 secs on my machine or android they are linux ... but very specialised one they are closer in that aspect to what does switchboot |
it's a know thing that when your kernel has to scan and locate proper drivers to fit your hardware in a driver library and load them as module that's the slowest way... | |
so the basic optimisation people were doing at the begining of linux was to adapt the kernel to integrate the specific driver needed for your hardware and only them... But this is flexible and doesn't fit with the hot plug need introduced by USB port and periphericals. | |
so now we have for example ubuntu 10.10 in netbook version which is basically a kernel with a driver module library that only fits the hardware you can find in the netbooks... as the hardware library is smaller then it boots faster | |
I use nosplash quiet and fast-boot options for my kernels ... doing this I gain 10 seconds in boot sequence. | |
after you can gain another 10 seconds of boot time just by using X11R6 + openbox windows manager instead of gnome + Metacity or kde etc... | |
maybe using wayland instead of x11R6 + compiz or metacity can speed up your boot sequence too | |
the closer you linux will be to your specific hardware the faster it will boot ... | |
but 1 second is still amazing .. I would say I this swichboot demo was about accessing to a regulare openbox window manager instead of a dashboard I would be already buying it :) | |
Henrik 14-Jan-2011 [5644] | Geomol, did yours come with a standard Apple SSD or your own? I'm interested in replacing the drive I have in my Macbook. |
Geomol 14-Jan-2011 [5645] | I bought it with SSD included. |
Henrik 14-Jan-2011 [5646] | ok |
Maxim 14-Jan-2011 [5647] | from cold boot, I remember being able to print a sheet on my amiga @28HMz before my friend's PC was able to finish booting Win95 on his pentium. :-) |
BrianH 14-Jan-2011 [5648] | That's what happens when you boot from ROM and implement a good chunk of the functionality in hardware rather than software :) |
GrahamC 16-Jan-2011 [5649] | Googlewave is now Apache Wave http://googlewavedev.blogspot.com/2010/12/introducing-apache-wave.html |
Henrik 29-Jan-2011 [5650] | http://www.youtube.com/watch?v=W18Z3UnnS_0 It's just getting worse and worse with those quadrocopters... |

Reichart 30-Jan-2011 [5652] | I found this more impressive... http://www.youtube.com/watch?v=ToACDIXTzo0 But.................. watch this http://www.youtube.com/watch?v=1k-u0_Y8hK0&feature=related We need to get this guy to sit down with the programmers of the Quad, and teach them how to make use of all aspects of flight. |
Oldes 30-Jan-2011 [5653] | I guess it will be pretty different. |
Henrik 31-Jan-2011 [5654] | http://www.portable-digital-video-recorder.com/shmoocon-2011-printers-gone-wild/ Networked HP printers contain a number of security issues. |
Maxim 31-Jan-2011 [5655] | I've had fun sending commands to printers a few years ago, its a lot of fun :-) |
Henrik 31-Jan-2011 [5656] | I did it too. I didn't find it particularly amusing, since different printers understand them differently. :-( |
Maxim 31-Jan-2011 [5657] | depends why you're playing with that... I was just hacking my printer for fun... trying to build a print manager... that's another story ;-) |
Henrik 31-Jan-2011 [5658] | I managed to build one, which is simple. Sending commands to the printer, I had to give up and chose to build postscript files for an adobe postscript driver instead and let it handle the rest. |
Henrik 1-Feb-2011 [5659] | http://www.exploringbinary.com/java-hangs-when-converting-2-2250738585072012e-308/ Interesting. Java has the same flaw that PHP had with a specific number. |
Henrik 2-Feb-2011 [5660] | http://googleblog.blogspot.com/2011/02/microsofts-bing-uses-google-search.html This is almost funny. |
DideC 2-Feb-2011 [5661] | Very funny ! |

Pekr 7-Feb-2011 [5665] | Nokia experiments with the Bubble interface - IIRC, it is QML based (Qt's VID inspired declarative aproach, second one, after JavaFX) http://www.geek.com/articles/mobile/nokia-experiments-with-bubbles-interface-on-symbian-cell-phones-2011024/ Just not sure I want to chase bubble around to get some action done :-) |
TomBon 7-Feb-2011 [5666] | a good design characterizing itself by immediate function transparency. this is....well...what is it? |
Henrik 7-Feb-2011 [5667] | one quick improvement would be to make the bubbles not move. |
Reichart 7-Feb-2011 [5668] | LOL! (that is all I can say about the bubbles) oh wait..........now the "LOL" has floated down here in the message.......whoa..............it floated over here "LOL". LOL... |
Andreas 7-Feb-2011 [5669] | debian 6.0 "squeeze" released http://www.debian.org/News/2011/20110205a |
GrahamC 9-Feb-2011 [5670x2] | http://www.zdnet.com/blog/btl/hps-touchpad-tablet-smartphones-put-webos-back-into-the-game/44636?tag=nl.e589 HP's impressive tablet using WebOS |
snapdragon I presume is an Arm processor | |
Pekr 10-Feb-2011 [5672] | Snapdragon is Qualcom's ARM based CPU/chipset. OMAP is Texas Instruments. Samsung has its own, nVidia has Tegra, Broadcom is another big one I know. Full list of licensees can be seen here: http://www.arm.com/products/processors/licensees.php |
GrahamC 10-Feb-2011 [5673x2] | If the HP's WebOs takes off .. maybe we don't need to port to Android :) |
Isn't WebOS a Linux variant? | |
Ashley 10-Feb-2011 [5675] | Yes, "a proprietary mobile operating system running on the Linux kernel, initially developed by Palm and purchased by Hewlett Packard (HP) in 2010." |
BrianH 10-Feb-2011 [5676] | We need an Android port. Otherwise, how would I run R3 on my phone? |
Robert 10-Feb-2011 [5677] | I'm convinced that HP will succeed to fail with WebOS. Wrong CEO and a lot of HP products are mostly crap. |
BrianH 10-Feb-2011 [5678] | HP has been succeeding with crappy products for years, so they might succeed with this. Too big to fail completely. |
GrahamC 10-Feb-2011 [5679x3] | HP's slate runs flash .. you need flash to view porn. Ergo, this slate will sell. |
Furthermore, HP has been giving away slates free with their printers .. as printer control devices. | |
They can continue to do that for their servers | |
Henrik 10-Feb-2011 [5682] | Well, at least they just straight up copy the iPad now. I'm sure they only announce now, because the iPad is about to be updated. |
