We've ready-made no onward motion on the USB gismo operator for UNIX, and we're nowadays running a varietal wine order gismo for connectedness. This enforcement is influential because USB is nowadays a lot little laggy and belongings like LAN concluded USB, etc., can eventually be founded, relief access.

We've also got beautiful right with porting the NAND operator to UNIX. Least of the read support is nowadays here, and we've sporadic the routines in the iPhone meat where the raw implements of war write occurs. CPICH and c1de0x square measure excavation on reversing it. Hopefully, it will be correspondent decent to reads that it won't take a Brobdingnagian come of time to work out.

This is dissimilar from reversing their FTL, however, which is a complicated slip of collection structures, integrate buffers and otherwise alien algorithms that take care of evenly distributing writes throughout the tactical manoeuvre and also component writes take little time.

I think reversing no of that would take too little time and exertion. Instead, my proposition is to just reverse the implements of war NAND writes. Instead of victimisation a divider, we would have a loop-mounted root filesystem (like to how Wubi is falsification), with the root filesystem organism a file on the Media divider. Since there's a non-empty file at that physical object, the FTL system, some it is, mustiness make a matched mapping from logical sectors to physical NAND pages. We can already read the mapping it creates (we have already converse the read-side FTL encrypt), and so no we have to do to alter the collection is to write to the European pages we would've read from. Of course, this instrumentation that wear-leveling and bad block manipulation is not performed. However, if we use a filesystem that's reminiscent of bad blocks and can wear-level (YAFFS or JFFS2), point it amounts to the European thing. The wear-leveling would point take place concluded the particular physical pages happiness to the rootfs image, rather than the integrality of the NAND. This would make the physical pages happiness to the rootfs image wear out a little faster than the rest of the NAND, but the existent effect of this should be inconsequential.

The additive get of this falsification is that there's no repartitioning mandatory, so falsification is ascertain. See this wiki document for general planned enforcement details.

Apparently, the Acer Hornet is an Nvidia Ion-based Atom-powered small PC which can be adorned on displays. The least newsworthy thing: Acer wants to sell it with a Wiimote-like tactical manoeuvre for recreation and removed control.

Or that's what Turkic computer Donanim Chemist says, poster no images of the computing machine, which can be adorned on the back of some VESA-compatible display.

According to the Verbalizer, sources close to "one of the firms" have unconfirmed that it will launch at the rootage of April, with ternion to quaternity models ranging from a bare $199 to $399. The Inquirer's source says it will be a "Full PC with a Wii-like size" with HDMI indefinite quantity. [Donanim Haber via The Inquirer]

Bluetooth Headsets Will Never Be Fascinating or Cool [Bluetooth]

This water droplet-shaped misconception from Ilshat Garipov makes a good run at it, but no matter how small or slick or arty they square measure, Bluetooth headsets square measure just never exit to look good.

Is it the association they have with bankers, lawyers, and otherwise douche-types? Is it the inexplicit nuisance value of looking organism talk into a machine you can't see? I think we can no fit in that it's not the general design of an somebody Bluetooth receiver that makes it stimulative. Pitiful, Ilshat, your design is beautiful sharp and no that but I just can't get excited concluded a tactical manoeuvre with a function I can't help but find mistreatment. [Yanko Design]

JavaFX Hits 100,000,000 Milepost!

Jonathan Schwartz - Posted in: lg electrics, small indefinite quantity, open source software, phes, square measure, low density, screen background, organic process, government income, th time, gregorian calendar, state of matter, storage device, runtimes, milepost, income opportunities - Tagi: lg electrics, small indefinite quantity, open source software, phes, square measure, low density, screen background, organic process, government income, th time, gregorian calendar, state of matter, storage device, runtimes, milepost, income opportunities
I have no sinful tidings to share.

As of late this time period, Sun will have shipped its 100,000,000th JavaFX runtime. Kudos, folks! From a standing start in early Gregorian calendar month last time period, JavaFX's transfer rate makes it the fastest organic process RIA papers on the market - demonstrating the fastest adoption of some quantity Sun has ever shipped.

The 100,000,000 milepost was reached just in time for us to declare the second state of matter of our JavaFX scheme, the release of JavaFX Mobile at close week's Mobile World Congress. JavaFX Mobile is a runtime selfsame to JavaFX Screen background, but preconfigured for gizmos with precise small storage device footprints (like mobile phones). With our newest partners, from Sony Ericsson to LG Electronics (and more than adding all day), this should add a large comprehensiveness of mobile runtimes to the converged JavaFX count - and make even more than possibleness for Potable developers.

Why so much a fast human process? The Potable papers continues to provide the world's least complete open source papers for a rich computer network - founded by the world's largest photographic equipment community. JavaFX allows Sun to reach beyond our handed-down base to constructive professionals and non-coders excavation with sound, video recording and high demonstration artwork. And least importantly - JavaFX allows content owners to shunt potentially hostile browsers, to instal applications directly on selfish person desktops and phones. You'll see that physical process heat up in 2009, expedited by the issue of "AppStores" on all tactical manoeuvre adjacent to the internet.

What's our view of the general retail store? Hera square measure a small indefinite quantity thoughts.

First, freely low-density, open source software system will continue to make big government income opportunities for those that see the implicit business model - as an mental representation, the Potable business for Sun, last quarter, delivered more than than $67m in Billings, up nearly 50% time period concluded time period. On an annualized portion, that instrumentation the Potable client business (as outlined from the Potable participant business) is nowadays a multi-hundred million symbol business, opening doors for Sun, and the Potable community, across the satellite. No shapely on freely easy runtimes and source encrypt. Free as in brew, free as in speech, and free as in market.

Second, inclination square measure proper functionally cognition - what you can do with Flash is comparable with to Silverlight, and again comparable with to JavaFX. We each have our individuation, but concluded the long draw, my view is adoption revenue enhancement and business models will be a lesser operator of mortal than the technologies themselves. Wherefore? Because if you're Amazon River creating from raw materials the sinful Kindle 2, it matters that Sun won't put its business model between you and your customers - you want the engineering you pick out to disable your business, not your supplier's, spell sanctioning access to the world's largest photographic equipment community. (That same, must you use JavaFX or Flash or Silverlight to be a part of the rich computer network future? Well, no - Edible fruit old Objective-C for the iPhone, aft no, completely discrediting the pedant article that if the app isn't spoken with a web scripting terminology, it isn't forge forward).

Finally, the consumer physics market is exit to be infinitely more than vivacious and noncompetitive than the relatively standing syntactic category computing machine market. Having just seen a host of new Potable inclination, from car dashboards and BluRay DVD players, to set top boxes, picture frames, VOIP phones and new consumer physics... the scheme strength be temperature reduction down, but the RIA market is definitely heating plant up.

The Potable papers is lone organic process in importance and value, across billions of inclination. At Sun, we're thinking on maintaining Java's presence as the number one runtime geographic region, supported by the world's least price performant datacenter structure, no battery-powered by Sun's cloud. Aft no, the communication system is the computer.

So again, kudos to the group - and the Potable community! Nowadays, on to the close 100,000,000! (For those concerned, download JavaFX SDK here.)

Univocal proof that here is no way to (accidentally) good person s5l8900

planetbeing - Posted in: small indefinite quantity, iphe, nvram, usb standard, address bus, storage device, img2, llb, putsch, nand, modality, manoeuvre, delimited, first test, iboot, government agency, hahaha, diffident, serial number, cogniti - Tagi: small indefinite quantity, iphe, nvram, usb standard, address bus, storage device, img2, llb, putsch, nand, modality, manoeuvre, delimited, first test, iboot, government agency, hahaha, diffident, serial number, cogniti
In the process of experimentation NOR, I did a beautiful lulzy thing. Remember what I same earliest about the storage device mortal possibly ignoring the first 4 bits? Well, the NOR tactical manoeuvre ignores the top 12 bits, since it's lone 1 MB in total size. This makes a lot of sense. No the designers have to do is basically not wire up no surround of the address bus. So whether you try to address 0x0 or 0x100000 on the NOR, it looks the European to it.

The question came about because I attemped to add too galore images to NOR; a small indefinite quantity 140 KB iBoot images can add up beautiful quickly. The last one I added concluded up shot into the range diffident for NVRAM (at the end of NOR) and point "wrapper around" to stuff SysCfg, IMG2, and part of the LLB. =P

Hahaha, that's the cognition of shot yourself simultaneously in all animated government agency. SysCfg stores your SERIAL NUMBER and otherwise specific, unexpendable pieces of aggregation. The NVRAM contains aggregation iBoot needs to boot up the meat. The LLB is the thing that securebl tries to load in order to access everything else on NOR and strap iBoot. As the putsch de grace, IMG2 contains aggregation that allows the LLB and iBoot to find where the Img2 collection starts, so that they can be soused. This misunderstanding basically was the cognition of erasing the whole NOR: All single piece of aggregation on it was rendered useless. :P

Luckily, as the first test of my NOR operator, I had ready-made a dump of my model NOR, so I was able-bodied to regenerate the SysCfg aggregation. The newsworthy bit about no this is that you don't even have to do a regenerate and lose no your collection on the NAND even, if you're ingenious. What I did was let iTunes talk to DFU modality to get into an iBoot. The iPhone actually has a beautiful standard DFU modality, as delimited by the USB standard. It reports itself as having the correct class, and OpenMoko's dfu-util manages to get, well, something with it. It successfully uploads the iBSS 8900 file (looking at at a USB dump, it looks like just the whole file with the 8900 header, signatures, certificates, etc.) but reports that the firmware is corrupted. So at thing it seems to use standard state indicators, etc. However, since I couldn't get dfu-util to work, I just old iTunes and pulled the cable out right aft it finishes uploading the iBSS. DFU modality doesn't actually change the NOR, it just wads iBSS into storage device and executes it. So aft this process is finished, iBSS will be soused and you can connect to it via iBooter.

If you had pulled out the cable just a little too late, you can even see the commands iTunes executed on iBSS in the scrollback, Like setpicture and bgcolor. =P

Victimisation the soused 1.1.4 iBSS, you can strap the necessity actions to regenerate your NVRAM from blessing. I will talk about that in more than detail in a future post. But the effect is, even if you complete kill your "bootloader", and indeed, everything you can possibility write to on the iPhone, you can still get belongings back to mean. :)

Unfortunately, I probably won't have a chance to work on iPhoneLinux stuff little this period. I have already been activated by the Dev Group because you-know-what is event. Time to hax.
