NAND flash memory-based storage devices, such as SSD, eMMC, and SD cards, have been widely being used for ranging from mobile to server systems. Since they are known to have different characteristics from the conventional rotational disks, a file system, an upper layer to the storage device, should adapt to the changes from the sketch. F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead. Because a NAND-based storage device shows different characteristics according to its internal geometry or flash memory management scheme aka FTL, we add various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms. ...

El tiempo… ese bien tan preciado para muchos, tan desperdiciado por la mayoría… Eso que los relojes nos ayudan a medir o controlar a diario. Hablemos de relojes. Los hay de muchísimos tipos: de muñeca, de pared, analógicos, digitales, con números arábigos, con números romanos, o hasta sin números. Y, evidentemente, los hay con motivos friki-matemáticos. Y de esos son los que vamos a ver a continuación, de relojes matemáticos. ...

This project is based on the entire ABC’s LOST TV show scripts, 115 episodes in 7 seasons, that I managed to parse from Lostpedia. I also parsed this page with additional information about hidden characters relations. My aim for this project is not (only) to visualize some properties and patterns out of the script but actually to allow to read and enjoy the series in a different way. I plan to add new views (will inform through twitter), more aimed to reveal global patterns in the script, and I will include cliffhangers and writing teams information. Find more information about Lostalgic in this great article and interview by Greg J. Smith in Creative Applications. This project is dedicated to the Lost writers, to the open culture and, in particular, to the community that built Lostpedia. ...

You are looking at the HoneyMap, a real-time world map which visualizes attacks captured by honeypots of the Honeynet Project. Red markers on the map represent attackers, yellow markers are targets (honeypot sensors). » Florian Weingarte and Mark Schloesser | HoneyMap / honeynet.org

A major security vulnerability has been discovered in some TouchWiz-based Samsung smartphones, including the Galaxy S2 and certain Galaxy S3 models on older firmware. The bug was first demonstrated days ago by security researcher Ravi Borgaonkar at the Ekoparty security conference. It involves the use of a single line of code in a malicious web page to immediately trigger a factory reset without prompting the user, or allowing them to cancel the process. Even more serious is the possibility that this could be paired with a similar glitch to render the user’s SIM card inoperable. And as the malicious code is in URI form, it can also be delivered via NFC or QR code. ...

In the world of hackers, the kind of answers you get to your technical questions depends as much on the way you ask the questions as on the difficulty of developing the answer. This guide will teach you how to ask questions in a way more likely to get you a satisfactory answer. Now that use of open source has become widespread, you can often get as good answers from other, more experienced users as from hackers. This is a Good Thing; users tend to be just a little bit more tolerant of the kind of failures newbies often have. Still, treating experienced users like hackers in the ways we recommend here will generally be the most effective way to get useful answers out of them, too. The first thing to understand is that hackers actually like hard problems and good, thought-provoking questions about them. If we didn’t, we wouldn’t be here. If you give us an interesting question to chew on we’ll be grateful to you; good questions are a stimulus and a gift. Good questions help us develop our understanding, and often reveal problems we might not have noticed or thought about otherwise. Among hackers, ”Good question!” is a strong and sincere compliment. ...

Dear Sen. Rockefeller, I am a cyber expert. I invented a key technology known as ”IPS” that is a standard part of network defense. I invented hacking techniques like ”sidejacking” that are a standard part of network offense. I am a coder who has written a million lines of production code. I am a ”pentester” who has performed simulated attacks that confirm your worst nightmares about power-grid blackouts and financial meltdowns. Your letter [*] was na¯ve. There is no such thing as ”best” practice, because there is no such thing as ”adequate” practice. The Fortune 500 has not figured out how to stop Chinese hackers from breaking into web browsers, or how to separate code from data injected into websites, or how to stop an inadvertent connection between a secured and unsecured network. This has allowed me to hack (in tests) into Fortune 500 companies, even those that follow the very best of ”best practice”. ...

Cosmo is huge ” 6 foot 7 and 220 pounds the last time he was weighed, at a detention facility in Long Beach, California on June 26. And yet he’s getting bigger, because Cosmo ” also known as Cosmo the God, the social-engineering mastermind who weaseled his way past security systems at Amazon, Apple, AT&T, PayPal, AOL, Netflix, Network Solutions, and Microsoft ” is just 15 years old. He turns 16 next March, and he may very well do so inside a prison cell. Cosmo was arrested along with dozens of others in a recent multi-state FBI sting targeting credit card fraud. It is the day before his court date, but he doesn’t know which task force is investigating him or the name of his public defender. He doesn’t even know what he’s been charged with. It’s tough to narrow it down; he freely admits to participation in a wide array of crimes. ...

It’s September of an election year, and people are drawing lines, taking stands, and proclaiming their political beliefs. Even the lurkers, who brag that they ”never post political stuff on Facebook” find their trigger fingers twitching over the ”share” button. The internet is a battlefield, and you simply can’t get around online without being drawn into a shootout from time to time. When that happens, these tips will keep you knocking down opponents without losing your cool or becoming a troll. ...
