One small developer says that he’s readied an open-source alternative to Microsoft’s exFAT file system, providing companies and individuals with a free alternative to Microsoft’s file system for flash drives.Over the weekend, developer Andrew Nayenko announced fuse-exFAT 1.0.0, completing three years of development on the project. Tarball archives have been posted to Google’s code site, where they can be compiled for GNU/UNIX based operating systems and Apple’s OS X.And that could mean a loss of revenue for Microsoft, which has been busy licensing its exFAT file system to a number of companies. Last week, for example, Microsoft licensed the exFAT tech to automaker BMW for an undisclosed amount. It has signed similar deals with Aspen Avionics, Canon, Panasonic, Research In Motion, Sanyo and Sony.Why Is This Important?A file system manages the locations of computer files stored on a drive; in Windows, for example, PCs have used the NTFS file system since the days of Windows 2000. (Microsoft planned to include a new file system into Windows 8, called ReFS, but that system has been reserved for Windows Server.) Apple uses its own Hierarchical File System, with an improved version, HFS+, in OS X. The vast majority of consumers and businesses never have to worry about which format is used on which drive, as products like USB keys and external hard drives can be read by both Apple and Windows systems. Those external devices – including the SD cards used by most consumer cameras – are typically formatted with a file system called FAT32.But as cards themselves increase in file size, the file system’s role becomes more prominent; for example, SD HD cards up to 32GB are formatted with FAT32. But for the newer SD XC cards, from 32GB on up to a (largely theoretical) limit of 2 terabytes, the SD Card Association has flipped over to the exFAT file system.That’s important in an increasingly connected world. In a statement, BMW’s project manager for CE device connections, Gottfried Schmid, explained that “with the support of the trend-setting file system exFAT, BMW is able to significantly increase the number of compatible CE devices and Mass Storage devices for our customers.” But the license agreements Microsoft has signed cover a number of traditional camera and phone manufacturers that are seeking legal shelter.The Legal MessIt’s still too early to tell whether Nayenko has managed to reverse engineer exFAT using open-source technologies, however. Microsoft hasn’t divulged many details of the the exFAT file system; in 2009, the SANS Institute attempted to reverse-engineer the exFAT file system to enable forensic examination, such as sensitive images that may have been stored on a camera. Microsoft maintains a licensing page specifically devoted to licensing exFAT technologies, and company representatives declined to comment when asked if Nayenko’s technology violated the company’s patents.Nayenko is presenting the exFAT file system as a FUSE model, a loadable kernel module that essentially serves as a bridge to the actual kernel interfaces. FUSE is licensed according to the GNU public software license.The few people who are aware of Nayenko’s release have begun asking whether or not businesses or other commercial entities interested in using fuse-exFAT within their own products may legally do so. Last year, Nayenko said that he didn’t believe that Microsoft could touch him. “Fortunately U.S. laws are not worlds [sic] laws,” he wrote in a message to the Google newsgroup.On Tuesday, he took a more laissez-faire approach. “I don’t know,” Nayenko responded, when I asked to interview him about the legal standing of fuse-exFAT. “You should consult a lawyer. I run this project just for fun and don’t care about patents because I’m not a U.S. resident.”It’s easy to draw comparisons between fuse-exFAT and Linux, and the battles between the open-source community and Microsoft in the late 1990s. Linux, however, was designed as a new OS kernel, not as a clone of existing Microsoft technology. While Nayenko may have designed a version of the exFAT file system that truly exists independently of Microsoft, any company selling products based on fuse-exFAT within the United States will probably face a legal challenge from Redmond.Image source: Flickr/Le ciel azure markhachman Related Posts IT + Project Management: A Love Affair Massive Non-Desk Workforce is an Opportunity fo… 3 Areas of Your Business that Need Tech Now Tags:#flash#Microsoft#Open Source#Patents#storage Cognitive Automation is the Immediate Future of…

McGregor’s going to get mugged.”Safety fearsThe hard-nosed heavy-hitters of the gambling world agree.Saturday’s fight is set to smash records as the most bet-upon bout in Las Vegas history.

Former Australian captain Ian Chappell has heaped praise on Mahendra Singh Dhoni, saying the Indian captain was in good form both as a player and captain during the ICC World Twenty20.Chappell, an outspoken commentator, said India would be happy to see Dhoni lead them in the shorter formats for now.”Well! I think he was in form in T20. It means as a player and as a captain. He captained pretty well in the T20. We don’t have him as a Test captain but we want him and I think he was too good in World T20,” Chappell said on ESPNcricinfo programme ‘Match Day’.An Australian scribe had asked Dhoni if he was contemplating retirement in the press conference shortly after India were handed a heartbreaking defeat by West Indies in Mumbai last night. Dhoni stepped down the wicket to deal with the question and the reporter with panache and indicated that he was not going anywhere at least until the 2019 World Cup.Chappell said that India’s total of 192/2 should have been good enough for them to defend but he lashed out at Ravindra Jadeja, who leaked 48 runs in his four overs.”I think they would be quite happy about that. Anything above 190 or more than 8 an over, you feel you can win. There are not more games you lose.””Jadeja seem to control the delivery when there is help. When there is no help, he loses control.”Chappell said India tried but could not contain the West Indian batsmen from scoring the bulk of runs (as many as 146) through boundaries.advertisementThe 72-year-old felt the West Indies were not great on the field in the semi-final but made up for that with their ability to produce the big shots.”You think about the things West Indies do. They are not great runners between the wickets. They were not very good in the field today. Without these you cannot make up except hitting those sixes and fours.”Dhoni has had a dream run in 2016, leading India to victories over Australia and Sri Lanka in back-to-back T20I series before lifting the Asia Cup T20 in Bangladesh. Touted as pre-tournament favourites ahead of the World T20, India would have to now reconcile with a semi-final exit in the second ICC tournament in two years.

Tottenham ended their International Champions Cup tour on a high as Georges-Kevin N’Koudou’s 47th-minute strike gave Spurs a 1-0 win over AC Milan.N’Koudou scored powerfully a minute into the second half to put Premier League side Tottenham in the ascendency after Milan had created the better chances in the opening period on Tuesday.The French winger could have doubled Tottenham’s lead but he was denied by Gianluigi Donnarumma, whilst Patrick Cutrone and Franck Kessie came closest for the Rossoneri – who are reportedly close to signing Juventus pair Gonzalo Higuain and Mattia Caldara – in Minnesota.

Every time serial data rates increase, they expose problems masked at slower speeds. Many of those problems occur because of decreased signal integrity from losses that occur in PCB traces, vias, and connectors. There are many possible solutions to signal-integrity problems, but each one comes with a downside. One such response to the problem is to eliminate PCB traces using cable assemblies.Here’s the problem. Boards used in servers and switches are often quite large and they typically have “out of the box” I/O copper or fiber) on one end and a backplane connection on the other. To minimize the overall distance that a signal travels, PCB designers will place the switching IC (FPGAs or ASICs) in roughly the center of the board. Sure, you can minimize signal losses between the outside I/O and the switch devices by placing them close together, but that only worsens signal integrity from the ASIC or FPGA to the backplane.With signal fundamental frequencies currently at 14 GHz, losses caused by skin effect, weave effects, surface roughness, vias, and connectors are often too much for reliable communications. Even though receivers can detect incoming signals as low as 38 dB below the signal amplitude at the transmitter, there can frequently still be too much signal degradation.A 28 Gbit/s non-return-to-zero signal has a clock rate of 14 GHz. To help with signal losses at 56 Gbits/s, many engineers are moving to 4-level pulse-amplitude modulation (PAM4), which doubles the data rate for a given signaling rate versus NRZ. Thus, a 14-GHz clock can deliver 56 Gbits/s using PAM4, but there’s a problem. The signal amplitude (eye height) of a PAM4 signal is one-third that of an NRZ signal (Figure 1 ). That creates a tradeoff between signal loss and sensitivity to noise.Figure 1. The eye opening of a PAM4 signal (right) is about one-third the height of an NRZ signal, which makes PAM4 signal more prone to errors from noise. Scott McMorrow, CTO of Samtec’s Signal Integrity Group, has developed a spreadsheet that shows, in tabular and graphical form, the differences in loss (dB) for lengths of for Megtron6 PCB materials and cable sizes from 28 AWG to 36 AWG at frequencies from 1 GHz to 50 GHz. Distances cover 1 in., 12 in., and 1 m. You can use the data to estimate signal losses in your designs.To alleviate the PCB loss problem, several connector companies, including Molex, Samtec, and TE Connectivity have developed interconnects that let signals bypass PCB traces. The cable assemblies come in several flavors, depending on the application. For example, they connect I/O (often optical modules such as QSFP) to ASIC, ASIC to backplane, board to board in place of a rigid backplane and chip-to-chip on the same board. Figure 2 shows an example of a jump-over cable, this from a demonstration at DesignCon 2017.Figure 2. Jump-over cable assemblies let signals bypass PCBs between I/O connectors and ASICs or FPGAs. They are available with straight or right-angle connectors. Source: Samtec “Using cables for 56 Gbit/s signals cut losses by about half over using PCB traces,” said Nathan Tracy, Technologist, System Architecture Team and Manager of Industry Standards at TE Connectivity. The plot in Figure 3 compares losses for several PCB materials and for cables of two sizes as a function of frequency. As you might expect, the heavier 30 AWG wire has lower loss than the 34 AWG cable. But, lower loss comes with a tradeoff, Greg Walz, Advanced Technical Marketing Manager at Molex, warns that lower loss cables also don’t dampen reflections as much as those with higher loss. The increased reflections could increase the noise floor, which is critical to PAM4 encoding, especially on shorter length cables. Thus, you still need to balance loss with reflections and noise.Figure 3. Use this table to compare losses of PCB materials and wires as a function of frequency. Continue Reading Previous It’s alive!
