This document discusses asynchronous computer chips as an alternative to traditional synchronous chips. Synchronous chips rely on a central clock, which poses problems like slow speed, wasted energy distributing the clock globally, and high power consumption from the clocks themselves. Asynchronous chips do not use a central clock and instead rely on handshake signals between components to transfer data only when needed. They allow different parts to work at different speeds and immediately pass results. While asynchronous chips have advantages like lower power usage and less noise, challenges remain in interfacing them with synchronous devices and a lack of expertise and tools available. Overall, the document argues that asynchronous chips may help address future issues with clocked designs as chip complexity increases.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

3. • Bluejacking
– Sending of unsolicited messages over Bluetooth to
Bluetooth-enabled devices such as mobile phones,
PDAs or laptop computers via the OBEX protocol.
• Origin
– Started after a Malaysian IT consultant named
“Ajack” posted a comment on a mobile phone forum.
5. • Short range wireless LAN
• Connects numerous devices of different functions like telephones,
notebooks, computers, digital cameras etc. , in Personal Area
Network (PAN).
• Three areas - Data and Voice access points, Cable replacement, and
Ad hoc networking.
• Supports point - to - point as well as multi-point.
• Low power
• Low cost single chip radio – feasible
6. Piconet
• The devices find each other and form a network called “
piconet ” spontaneously.
• A piconet is a basic unit with up to 8 nodes, one of which
is a master and up to seven active slave nodes within a
maximum distance of 10 meters.
• All communication between master and slaves.
• Piconet is a centralized TDM system.
• Master controls clock and decides the time slot for the
device.
• In a piconet , there can be up to 255 parked nodes.
• Master switches to low power state and parked node wait
for beacon from master.

sends a file to them (spam's them) if they support
OBEX.
• By default a small text will be send.
11. Customize the message that should be send you need
a palm with an SD/MMC card, then you create the
directory /PALM/programs/BlueSpam/ Send/ and put
the file you would like to in into this directory. Activity is
logged to /PALM/programs/BlueSpam/Log/log.txt.

16. Do not hack any device
Don't send abusive messages
Don't threaten anyone
Don't put your personal information in a BlueJack message
Don't reveal yourself to the 'victim'
Do disable Bluetooth if you don't want to be BlueJacked
18. Is the unauthorized access of information
from a wireless device through a Bluetooth
connection, often between phones,
desktops, laptops, and PDAs.
Even if your device is hidden bluesnarfing
can also be done.
19. Provision of any small digital media to
suitable media provisioning enabled devices
over Bluetooth via the OBEX protocol.
20. Form of Bluetooth attack.
Allows the user to take control of a victim's
phone to call the user's phone.
21. Earlier issue
Promotes an environment that puts consumer devices
at greater risk.
Complete memory contents of some mobile phones
can be accessed by a previously trusted paired
device.
Phonebook and calendar can be obtained without
owners knowledge.
22. Present Scenario
primarily occurs in public spaces
Security issues previously involved with
bluejacking has been resolved.
In order for information to be duplicated, the devices
would have to be paired. Bluejacking does not require
a password to be entered and therefore the two
devices are not paired
23. Turn off your Bluetooth device until you need
to communicate with another user.
Buy an E2X bag.
› It blocks all transmissions and receiving signals
from leaving the bag.
24. Act as major sale tool
learn user preferences by placing options
like "more ads like this" and "less ads like
this" in each advertisement.
25. Because of its low cost and power
consumption this technology has a great
future ahead.
