Header/Bulkhead on 4 by 4 Shower? Type of Shower Door?
Hi, folks--I'm having a 4 by 4 shower installed--the cement board is up, the plumbing is in and the tile is being installed as we speak.
I've attached a pic of the shower as it looks now
The shower had a rainshower head and there is a light in the ceiling. The ceiling will be tiled. I plan to install a high-quality glass door.
Two questions:
--The installer and my carpenter are willing to install a header/bulkhead if I want one at very little cost. For this size and style of shower, would you recommend that?
--In the past (but this was with a six-foot-long shower with a header), I've had a Century glass sliding door that I've loved--great quality, gorgeous door. Should I go with a slider here or with a panel and swinging door?
Thanks for your help!
I vote for a swinging door. Not enough room for a slider.
It's too late now, but I would have also installed a regular shower head or a handheld spray. Only because not everyone likes getting doused from overhead. ; )

Thanks guys. Over 36,500 views. Did we hit 500 gallons yet?
SWMBO just phoned me to tell me she floated the Apfelwein keg. I guess I'll be bringing a keg in from the garage cooler when I get back in town and starting a new batch. That one only lasted 3 weeks.
If you just made some, rachet up the total gallons.http://www.homebrewtalk.com/showthre...=20383&page=11
Well, I tried to start my first batch today and got so darn excited I screwed the thing up... used nearly 5lbs of dextrose instead of 2... I guess if I start working on that airplane I've always wanted maybe I can use this for fuel?
Damn i'm an idiot. any ideas on how to salvage it?
I guess, I could try siphoning half of it into another carboy and adding 2 gallons to each carboy?
Of course then i've got 10 gallons of apfelwein that I don't even know if I'm going to like (although you all keep telling me that I will, so hopefully that's the case! lol)

Scooping corner sink cabinet on frameless cabinets- Pics?
I have a 39" corner sink cabinet. I was hoping to get a 33" sink in there, but am not sure.
I have heard a lot of people say "you will have to scoop the cabinet, " and some people have said they've done it here, but I haven't seen (& can't find it anywhere) what it looks like while it's being done & before the granite is on. I don't recall anyone saying they've done it with frameless cabs, so that makes me more nervous.
Does anyone have pics of their scooped cabinet sink install??
Since it's just mdf, how do we route out the "wood" to make the SS sink at the same depth as the rest of the top of the cabinets? Will it just fall apart?
Here are my calculations:
33" sink, lip over just the sink cabinet (1) wall= 6.25 to cabinet door ( presumably we'd have to add another inch for countertop overhang
33" sink, lip over 2 cabinet walls (would probably have to dig into sink cab. wall too) = 5.5" to sink cabinet door front
30" sink, lip over 1 cabinet wall= 4.75" to sink cab door front
I don't want to make a mistake here, but have no idea what to do. Please help!
Here's a pic of the corner sink (don't mind the off center ruler-thing and the support we screwed up to the right).
Do NOT scoop any frameless cabinet. Ever. That is an absolutely dangerous thing to do. It's dangerous enough on a framed cabinet, but the sides are the strength in a frameless cabinet and you're taking away all of the strength in an already weakly supported area. Your granite could collapse the sink base.
Use a 25" single sink like the base was designed for.
OK. Thanks for your response & I hope you can excuse my ignorance.
I was mostly just hoping to get the lip of the sink on the top of the sink cabinet walls (not actually scooping the walls of the cabinet, but thought I ought to ask the question). Do you think that's still inadvisable? I have considered ways to reinforce the cabinet as I recognize it's a large expanse.
If it is inadvisable, how much of the top MDF needs to exist from the edge? 1/2"? If 1/2", then a 25" sink would be 3.5" away from the edge of the granite (that includes the lip of the sink) My top mount corner sink now is 3.5 inches (including lip) from the edge of the countertop.
A 25" sink is a bit of a shock, as the cabinet company told me I could get at least 30" in. Thanks for any advice.
Maybe you can find a way to use a D shaped sink backwards?
one of the things i would have differently on my corner sink is the installation.
I would have turned the sink 45 degrees so that the longer side was front to back not side to side.
this uses up more of the space at the back that is sort of wasted.
it means the drain is on the side instead of the back
I do love my corner sink but often wish I had done the installation as described above.
This would certainly help you out
No scooping of a frameless cabinet unless you install a LOT of additional support to take the weight of the heavy counter and heavy sink full of water. And for those corner cabinets that don't go all the way into the corner, you should always make sure that there is a cleat on the wall at the rear to support the weight as well.
If you want a large corner sink, then a 42" sink base will just barely accomodate a full sized 33" sink. But only if you push it back further into the cabinet than is normal. Instead of the typical 3-4" inches from the front, you're talking 6"-8" back. That's bad on your back.
The other alternative choice when planning a corner sink is to take a regular sink cabinet and install it on the diagonal. That does eat up a bit more space unless you recess the sink cabinet into the corner a bit. I find sinks done that way awkward to use personally.

Program Manager Interview
I applied through a recruiter. The process took 4+ weeks – interviewed at Dun & Bradstreet in August 2012.
Recruiter reached out via linked in. I had a quick screen and I found the recruiter to be professional, polite and clearly someone who believed in D&B as a company. Her questions were general and were focused on making sure that I was up to speed on expectations and that I felt the opportunity was worth pursuing. I had three follow-up interviews and the feedback I received was very positive and after each interview I was told that I would be moved forward in the process. However, after the third despite being told that I would be moved forward D&B did not get back in touch. I followed up after 2 weeks and was told that they had decided to move in another direction.
- The questions were all behavioral and as such they were not difficult. That said I was not offered a position so...take my assessment with a grain of salt. Answer Question

This Gizmo's Rays Could Halt Even O.J.'s Bronco
By Jasper Perkins and Adam Aston, BusinessWeek
TV helicopter crews, your glory days may be numbered. Police in the car-chase capital of the world are getting set to stop fugitives in their tracks.
The Los Angeles Sheriff''s Dept. has ordered a high-energy radio wave device developed by Eureka Aerospace in El Segundo, Calif. Troopers will be able to use it to scramble the digital brains -- computer chips that control fuel injection, engine firing, and other functions -- in most cars. With its engine shut down, the targeted car would roll to a stop.
The ray, which proved effective at a range of 160 feet in testing in early July, projects from an antenna that can be mounted on the roof of police cruisers. The company is developing beams that could either permanently fry the car''s electronics or simply temporarily disrupt them.
L.A. has averaged over two car chases a day in recent years, causing interminable traffic snarls and nearly 300 collisions. The zapper will probably go into production for Tinseltown cops after a prototype is finished at the end of this year, says James Tatoian, Eureka''s chairman and CEO.

Stable servers. Seriously, that shit went down every other time I went to look for a match or a bit of created content.
Secondary to that, they need a massive update to the roster - stop recycling the same wrestlers and animations from the last ten years of Smackdown games already. I realize the CAW feature allows for the creation of practically anybody, but recyled animations and warmed-over taunts make it hard to really create unique feeling wrestlers. A more refined Universe mode is an absolute must, with the ability to make sure favorite wrestlers and/or feuds can be created and added with more regularity.
The CAW system is pretty okay, but a larger cap on the number of items that can be used or implemented would be a great thing. We probably won't see that until the next generation of consoles, but a fella can dream. Other than that, there are the usual suspects - make the crowd look better, less weird clipping, overhauled and simpler controls, and less goddamn HHH.
Yea, less Triple H.

WISER: Realistic and Scalable Wireless Mobile IP Network Emulator M. A. Kaplan1, A. Cichocki1, S. Demers1, M. A. Fecko1, I. Hokelek1, S. Samtani1, J. W. Unger1, M. U. Uyar1, B. Greear2 (1) Telcordia Technologies, Inc., Applied Research, Piscataway, NJ 08854 http://wiser.research.telcordia.com (2) Candela Technologies, Inc., Ferndale, WA 98248 ABSTRACT WISER is a scalable network emulation tool for networks with several hundred heterogeneous wireless nodes. It provides high-fidelity network modeling, exchanges packets in real-time, and faithfully captures the complex interactions among network entities. WISER runs on inexpensive COTS platforms and represents multiple full network stacks, one for each individual virtual node. It supports a flexible open source router platform (XORP) to implement routing protocol stacks. WISER offers wireless MAC emulation capabilities for different types of links, waveforms, radio devices, etc. We present experiments to demonstrate WISER's capabilities enabling a new paradigm for performance evaluation of mobile sensor and ad-hoc networks. Keywords: Emulation, virtualization, network performance, sensor networks, mobile ad-hoc networks, XORP. 1 INTRODUCTION Traditional approaches to evaluate performance of mobile sensor or ad-hoc networks include simulation models or small-sized physical testbeds. However, simulation tools typically do not run in real-time and rely on simplified models rather than a real system, while physical testbeds are prohibitively expensive to build and operate. In this paper, we introduce a scalable network emulation tool called Wireless Ip Scalable EmulatoR (WISER) for networks consisting of up to several hundred heterogeneous wireless nodes. WISER provides high-fidelity network modeling, exchanges packets in real-time, and faithfully captures the complexity of interactions among different network entities. WISER is built on non-proprietary Linux OS and runs on inexpensive COTS hardware platforms. WISER is able to represent multiple full network stacks, one for each individual virtual node. It supports a flexible open source router platform (XORP) to implement real routing protocol stacks such as OSPF, PIM-SM, and any other customized protocol. Furthermore, WISER offers wireless MAC emulation capabilities for different types of links, waveforms, radio devices, etc. under various mobility conditions. We present experiments to demonstrate the capabilities of WISER enabling a new paradigm for performance evaluation of mobile sensor and ad-hoc networks. Interoperability between a WISER emulated network of many virtual nodes and an actual physical testbed of laptops and routers is shown through OSPF convergence experiments. Additional experiments show multicast capabilities through PIM-SM convergence, QoS support with different DSCP values for various traffic types, and scalability up to nearly 100 nodes in a single computer. This paper is organized as follows. Section 2 provides an overview of existing emulation tools. Section 3 summarizes the modules of the WISER architecture. Key capabilities of WISER are outlined in Section 4. A representative set of experiments are presented in Section 5. 2 RELATED WORK Since the implementation, operation, and maintenance of physical testbeds are extremely costly, virtual machines (VM) and virtual networks have been an active area of research and development in the networking field. For example, VMware1 is a widely-used virtualization product but prone to I/O bottlenecks. Jail 2 partitions the operating system into independent process groups to achieve multiple VM environments, which is especially popular for ISP applications. However, jail does not provide a real VM because it does not allow the VMs to run different kernel versions. TWINE3 implements network stacks with a simulated physical layer, propagation models, and mobility models. Emulab4 is a modern VM emulator which virtualizes hosts, routers, and networks, while retaining near-total application transparency, performance fidelity, responsiveness suitable for interactive use, high system throughput, and efficient use of resources. Compared to simulation environments, Emulab provides more realistic testing grounds for developing and experimenting with software. However, it supports only static topologies and is not suitable for dynamically changing MANET environments. In another example5, a VM environment applicable to wireless nodes is presented, however it is not easily usable due to lack of automation capabilities in experiment setup procedures. Another approach to VM implementations is called pseudo-VM systems where multiple independent network stacks can be created within a single OS instance. A clonable network stack implementation6 using this approach is introduced for the FreeBSD Kernel, however, it is not designed as a commercial tool and does not include wireless emulation capabilities as in WISER. Unlike these existing VM tools and environments, which are not readily available for generalized virtual hosting applications for MANETs, WISER provides an easy-to-use automation environment for realistic and large scale wired backbones and wireless MANET scenarios as described in the remainder of this paper. 3 SYSTEM ARCHITECTURE WISER runs on any dedicated Linux machine running our modified Linux kernel. The system consists of both user- space and kernel-space components which interact with the physical hardware to create the emulated network. The key modules of the system are depicted in Figure 1a, which shows the core emulation logic contained in several user-space components which perform network design, routing, and wireless modeling. These user-space modules interact with the kernel to instantiate the underlying network infrastructure (virtual network stacks and virtual interfaces). Physical interfaces on WISER provide access to the virtualized network from external IP devices. WISER is built on top of Candela Technologies' LANforge product, which includes modifications to the 2.6.25 Linux kernel. The purpose of this customized kernel is to instantiate multiple network stacks through the use of various Linux entities including redirect devices (RDDs), VLAN (802.1q) interfaces, and virtual routers (VRs). We introduced RDDs as a new type of virtual network driver for WISER, used in pairs such that when a packet is transmitted over one redirect device, it is immediately received by the other, thus representing the physical endpoints of the emulated links. VLAN (802.1q) interfaces are used to provide connectivity to external network equipment, allowing users to logically connect IP devices to the system with an Ethernet cable and a configured VLAN switch. The kernel has been modified to allow for a larger number of such interfaces within a single box. Finally, VRs serve as the structure which organizes the redirect devices and VLANs per node, producing the physical organization of the network. Kernel routing rules are then set up so that any packet received within a VR uses a particular routing table when determining the next-hop and/or local delivery. For example, consider the flow of packets between an external sender and receiver connected to VR1 and VR3 (a) (b) Figure 1 (a) WISER system architecture and (b) example kernel infrastructure for a virtual network respectively in the kernel network configuration shown in Figure 1b. Packets transmitted from the sender first arrive at VR1 on VLAN interface eth0.101. VR1 then retrieves the next-hop from its routing table, subsequently forwarding the packets over its RDD interface to VR2. Next, VR2 consults its routing table and forwards the packets over its RDD interface to VR3. Finally, the routing table at VR3 indicates local delivery for the packets, which are delivered to the receiver on VLAN interface eth0.103. Wireless network characteristics are applied to packets as they traverse hop- by-hop over the RDDs as described below. When packets exit the VR, they are first placed in kernel-space outgoing queues instantiated through the Linux Traffic Control (TC) agent. The queuing disciplines are structured to treat network control, voice, video, and data traffic with the appropriate level of priority. Packets are then extracted from the TC queues by the MAC module, which copies packets to the user-space where they are queued for imminent transmission. The user-space queues represent the physical radio queues; it is here that a non-conflicting TDMA schedule is generated for releasing the packets. WISER slot assignment algorithms include (i) a round-robin scheduler, (ii) an approximation of a high-band networking waveform for ground-to-ground links, and (iii) an approximation of a network-centric waveform for ground-to-satellite links. Other types of waveforms can also be modeled as needed. When a packet is transmitted out of a user-space queue, it is returned back to the kernel where it will be released to the corresponding RDD at the next-hop VR. Routing in WISER is provided through XORP7, an advanced open source routing platform that enables layer-3 protocols. XORP includes an extensive library of protocols which can be activated in WISER, including RIP, OSPF, BGP, and PIM-SM. Each instance of each protocol exists as a separate process; collectively a unique set of the selected protocols are associated with each VR. XORP protocols run in real-time and populate the routing tables for VRs as they would in a physical network. User-defined protocols can also be included in the XORP protocol library if programmed for the XORP API. This routing flexibility is one of the most powerful aspects of WISER. The graphical user interface (GUI) of WISER displays the network topology, traffic load, link bandwidth and bit-error- ratio to assist users in experimenting with different network configurations and networking activities. Built into the GUI is the network generator which is used prior to runtime for designing an emulated network. Using this generator, one can arrange various characteristics of a networking experiment including the initial positions of nodes, waypoints, and background traffic. WISER can interact with any IP-capable device external to the virtual network. A designated physical Ethernet interface (eth0) on the WISER box is logically associated with the VLAN interfaces, of which there is one per node. This physical Ethernet interface is wired to an Ethernet switch, on which each port is associated with a unique VLAN inside the WISER box. Thus, when an external device is plugged into a port on the switch, the device can exchange traffic with the VR to which the port was configured. Except for an IP address assignment on the host, no additional configuration is required for WISER operations. Several experiments involving laptops, desktops, and COTS routers connected to WISER are described in Section 5. 4 WISER CAPABILITIES 4.1 Real-Time Emulation One of the necessary characteristics of an emulation system is its ability to provide users with an interactive, real-time representation of the target environment. To achieve this level of functionality in a wireless network emulator, it is essential for the system to guarantee real-time packet forwarding. Many systems fall short in this regard, however, as CPU intensive RF calculations grind forwarding to a halt, making users unable to accurately measure performance of their protocols and applications. WISER overcomes this obstacle by offloading the RF calculations as a preprocessing step during the network generation phase. Prior to an emulation experiment, the user designs a network through the WISER network generator, specifying the nodes and their waypoints. These movements are then compiled by the WISER RF module, which performs the relevant calculations and outputs a topology script that depicts node positions and link characteristics (i.e. bandwidth, BER) for all node pairs over the duration of the scenario at a configurable time interval. This script is then read by the WISER MAC emulator at runtime, applying the network effects as indicated. This pre-processing step yields a high-performance at runtime since CPU cycles can be dedicated almost entirely to packet forwarding and queuing. 4.2 Scalability WISER's unique virtualization capability allows users to quickly and easily perform experiments for large networks. In Telcordia, WISER is installed on a rack mount system featuring a 2 GHz quad-core CPU and 8 GB RAM. WISER has been used to emulate 100 nodes in a single box and can be linked together with multiple boxes to emulate networks on the order of thousands of nodes. 4.3 Mobility Support WISER has accurate models for node mobility in a network such that dynamic link characteristics can be represented in real-time. Using the WISER network generator, a user can assign waypoints to the nodes, defining their movement paths during an experiment. The user-defined motion is then validated against the node type (e.g., tank, truck, or Humvee) to ensure that the node is not moving faster than its expected speed. At runtime, WISER reacts as the nodes move, inducing link failures and breakages by varying the bandwidth and BER according to the WISER generated script. 4.4 Wireless Modeling WISER includes an extensive set of RF modules for emulating vital communication characteristics of real systems: • Propagation – includes TIREM8, free space and exponent-based path loss models • Antenna Settings – height, frequency, and surface refractivity constants • Shadowing – applies log-normally distributed effects to BER • Fading – Rayleigh model affecting ground-to-ground links • Rain/Natural Events – affects the ground-to-satellite links 4.5 MAC Scheduling WISER produces a non-conflicting TDMA MAC schedule to drive its packet forwarding engine. To create a valid schedule, WISER first performs a centralized edge-coloring over the network topology, assigning each link a color such that for any node, all links incident to that node are assigned a unique color9. We further enhance the schedule assignment by taking two-hop frequency reuse into account to emulate the behavior of real waveforms in the field. Traffic is then regulated such that only links of the same color within the two-hop radius forward packets at a given time. WISER also has the capability to customize its MAC based on user experiment requirements. 4.6 Routing Support WISER integrates with an advanced open source routing framework, namely XORP, to give the user flexibility over layer-3 routing protocol selection (e.g., RIP, OSPF, BGP, and PIM-SM). In addition, any user-defined protocol is supported in WISER if the user provides an implementation compatible with the XORP API. For example, we have implemented proprietary wireless protocols for soft-handoff10 and congestion control11 to demonstrate integration with customized protocols. 4.7 Compatibility with existing tools Because WISER is a Linux based emulator, instantiating kernel devices to represent network entities, it has the advantage of being able to support most Linux networking tools. Tools for network management and diagnostics, for instance, can be used in WISER in the same fashion as they are used in physical networks. Ping and Traceroute work natively in WISER to observe the delay or the hop-by-hop path taken between nodes. Iperf can be used to generate traffic for load testing and Wireshark can be run to examine packets at the virtual interfaces. Additionally, the Linux traffic control module is accessed through WISER, assigning a quality of service (QoS) scheme to the interfaces. Our QoS queuing disciplines are consistent with those of WIN-T networks12 but can be easily modified to reflect user-defined traffic control disciplines. Moreover, WISER is interoperable with other virtualization technologies such as VMware for quickly deploying a cost-effective external testbed or OPNET13 for which WISER provides a real environment to test simulation models. 5 SAMPLE EXPERIMENTS USING WISER In this section we present a set of experiments that highlight the important features of WISER. Unless stated otherwise, a pre-processed 15-node network topology, consisting of two ground networks and one satellite network, is used for all experiments. This 15-node network is instantiated within the emulator machine using the WISER GUI as shown in Figure 2. XORP processes (including OSPF) associated with each VR are created dynamically with automated WISER- defined network addressing. For example, the IP address of VR1's VLAN interface is set to 10.1.1.1. Since VR1 has four active neighbors (i.e., VR2, VR3, VR4, and VR5), four different pairs of redirect devices are created and configured dynamically (e.g., the IP address of VR1's interface which is connected to VR2 is set to 10.1.2.1 while the IP address of VR2's interface connected to VR1 is 10.1.2.2). The same automated addressing principle is applied to all VRs. Note that the satellite node serves as a layer-2 device (no routing protocol is running) and is configured with the subnet address of 184.108.40.206. After the VRs, redirect devices, and VLANs are instantiated and the XORP processes are started, VR14 VR8 VR15 VR13 VR10 VR7 VR11 VR6 VR12 VR9 VR4 VR1 VR2 VR5 VR3 Figure 2 Graphical User Interface for WISER the OSPF routing protocol running a different instance for each VR calculates the routing table for its corresponding node. For example, a partial view of routing table of VR3 for the 15-node network is displayed in Figure 3. The OSPF link costs are 1 for all ground-to-ground links while they are set to a higher value if two nodes communicate over the satellite link. The user drives the pre-generated mobility scenario using five different buttons (e.g., Reset, Pause, Play, etc.) under the Mobility panel in Figure 2. When the mobility is started, link characteristics which are obtained from the pre- generated mobility file are sent to the MAC emulation module to calculate the non-conflicting TDMA slots for the given network conditions. During the emulation process, the user can observe different link characteristics such as MAC schedule, slot-demand, BER, bandwidth, and traffic load by switching among different radio buttons under the Display panel. Non-conflicting TDMA slot schedules across the links can be viewed by clicking the Show Schedules button under the Display panel (a pop up window showing non-conflicting TDMA slots in different colors appears as shown in Figure 2). When the user clicks on either a link or a node object, the detailed information for the corresponding object is displayed in the Node/Link Info text area. For example, the detailed information for VR5 is shown in Figure 2. 5.1 Interoperability with external laptops and routers The purpose of this experiment is to demonstrate the interoperability of WISER with real IP-capable devices such as COTS routers and laptop computers. In this experiment, a laptop computer, connected to VR2, serves as a host machine while a COTS router, connected to VR3, serves as a stub network running the OSPF routing protocol. The physical connections are made through an external switch on which ports are configured appropriately to enable IP connectivity of these external devices with their corresponding VRs. The IP address for the laptop is set to 10.2.2.254 and for the COTS router 10.3.3.254. Figure 3 and Figure 4 show the partial view of routing tables obtained from VR3 and the COTS router, respectively. Note that the OSPF cost is set to 10 for the interface between the COTS router and VR3. These routing tables indicate that the OSPF messages generated by the VRs are successfully delivered to and decoded by the COTS router, and vice versa. The link costs to reach networks from the COTS router have an additional cost of 10 since any packet generated by the COTS router needs to traverse the interface of cost 10 before reaching VR3. The packet will use VR3's routing table after that. For example, the cost of reaching 10.7.7.0 from VR3 is 5 in Figure 3 while it is 15 from the COTS router in Figure 4. Figure 4 A partial view of routing table for the COTS router a Figure 3 A partial view of routing table for VR3 obtained Figure 5 Output of traceroute command from the using XORP CLI COTS router to the laptop VR8 VR7 VR6 VR1 VR2 VR3 Figure 6 Source-based multicast tree for group 220.127.116.11 Figure 7 A view of the multicast routing table for the COTS rooted at source node VR2 router connected to VR3 Another example of interoperability between WISER and external devices is shown in Figure 5, where a traceroute command is issued from the router to the laptop. The output of the traceroute command shows that the packets, traversing correctly VR3 before reaching VR2, behave as if they are in a real network. An important observation from Figure 5 is that the link delays are differentiated in WISER such that the wired link takes a few milliseconds while wireless connections require close to one second of round trip time. 5.2 Multicasting The purpose of this experiment is to demonstrate WISER's multicast capabilities. To enable multicasting within the emulated network, XORP is instantiated with a multicast process running Protocol Independent Multicast – Sparse-Mode (PIM-SM) for each VR, with VR1 as the default rendezvous point (RP). External hosts connected to WISER can then send and receive multicast traffic natively. Using the 15-node network depicted in Figure 2, we expand the physical setup for the multicast convergence experiment by connecting additional laptops to VR6, VR7, VR8, as well as a laptop behind the COTS router at VR3. Each laptop runs a multicast receiver, which has joined the multicast group of 188.8.131.52, while the laptop at VR2 runs a multicast client transmitting to the group. A close-up of the relevant topology and the resultant VR2 source-based multicast tree are shown in Figure 6. As expected, all laptops participating in the group of 220.127.116.11 display outputs indicating receipt of the multicast messages. Additionally, Figure 7 shows the multicast routing table populated by the COTS router which demonstrates the interoperability with the WISER multicast routing processes. The first entry in Figure 7 belongs to the shared tree for 188.8.131.52, rooted at rendezvous point 10.1.1.1 (VR1). This entry indicates that the packets for the group incoming on the interface Ethernet1/1 (the WISER connection) should be forwarded over the interface of Ethernet1/2 (towards the connected laptop receiver). The second entry belongs to the source-based tree, rooted at the multicast source of 10.2.2.254 (the laptop connected to VR2). Similarly, the messages sent to this group, received on interface Ethernet1/1, are forwarded over the interface of Ethernet1/2 to reach the connected receiver. Figure 8 QoS Topology (3-node) Figure 9 Scalable 75-Node Emulation in WISER 5.3 Quality of Service (QoS) Support In this experiment, we demonstrate WISER's use of the Linux traffic control (TC) module to enforce QoS requirements on the emulated network. The queuing rules are contained within a user-configurable shell script, which is invoked by WISER on the nodes' outgoing interfaces. The script instantiates queues for the traffic types of network control, voice, video, and data. This experiment is performed using a three-node topology connected in a linear arrangement as shown in Figure 8 where both links support 12 Mbps maximum bandwidth. Using an Ethernet switch, we connected a Linux laptop to VR1 as the traffic sender, and another one to VR3 as the traffic receiver. We exercise the TC QoS support by sending competing flows over the congested network and measuring their realized throughput at the receiver. Before injecting the flows, we first consider the effective bandwidth of the path from VR1 to VR3 (Figure 8). Although the nodes are connected by 12 Mbps links, the effective path bandwidth will be less since the two links compete for MAC scheduling slots. Furthermore, traffic arrival patterns may reduce the effective path bandwidth if the flows are unable to fully utilize their assigned slots (e.g., burstiness in a traffic flow makes the link unable to transmit a full slot worth of bytes during the slot interval). Theoretically, if both links were to consume the entire frame with an equal number of slots and transmit packets synchronized with the slot interval, the expected path bandwidth would be exactly 6 Mbps. However, the expected bandwidth will be less than 6 Mbps due to schedule fluctuations and other factors such as packet arrival patterns. During the experiment, the effective rate was measured at slightly over 4 Mbps. Using iperf, we then initiated two competing UDP flows from VR1 at 5 Mbps each. Figure 10 shows the received throughput of each flow at VR3. Initially, when both flows are marked as best effort traffic, each flow obtains half of the effective bandwidth which is approximately 2 Mbps. At around 700 seconds, we use iptables to set the DSCP bits to 0x2C (voice class) at VR1 for one of the flow's outgoing packets. Based on the rules in our TC script, voice and data are allocated 50% and 20% of the bandwidth, respectively. The remaining unused allocation is then proportionally distributed to the active queues to fully utilize the available bandwidth. As seen in Figure 10, the high-priority flow is granted about 75% of the bandwidth, transmitting at about 3 Mbps, while the low-priority flow is throttled to just under 1 Mbps, 25% of the available bandwidth. Finally, at 1300 seconds, we set the voice flow back to data class, and the Figure 10 Throughput performance of competing UDP flows under QoS bandwidth becomes equally shared between the flows. These results verify that WISER can successfully support QoS requirements for a given scenario. 5.4 Scalability Lastly, to demonstrate that WISER can run a large-scale emulation in real-time in a single computer, we constructed a scenario of 75 nodes spread over the terrain in groups of 10 nodes each, with one highly concentrated group of 20 nodes. Some of these nodes are visible in the zoom window of the WISER GUI as shown in Figure 9. Each of the 10-node groups contains one node with satellite connectivity, enabling a mesh of about 50 nodes via ground-to-ground and ground-to-satellite connectivity while the remaining nodes reside in a separate physical island. We verified routing convergence and network connectivity by automated processing of the routing tables of WISER (the output is not included here due to its large volume). 6 CONCLUSIONS In this paper we presented WISER, a scalable network emulation tool for wireless mobile ad-hoc networks. Through virtualization of multiple network stacks within a single box, WISER emulates the complex interactions among network entities by running real protocol instances of layer-3 and above over highly accurate wireless link layer models. Interoperability experiments presented in this paper show that successful exchange of OSPF messages occurred between VRs and real physical devices such as a COTS router. For multicast support, we constructed a network of WISER nodes, laptops and a COTS router, and demonstrated PIM-SM convergence. Additional experiments show the WISER capability to differentiate low and high priority traffic in QoS applications, and its scalability with respect to number of nodes emulated in a single computer. WISER's rich set of capabilities thus enables a variety of realistic network experiments and provides a new paradigm for performance evaluation of mobile sensor and ad-hoc networks. REFERENCES 1. J.

(CNN) — Get ready for some of the coldest weather in decades.
About 140 million Americans are bracing for a polar blast that's barreling across the country this week, shattering records in some places..
Much of the United States will see the coldest temperatures in almost 20 years, the National Weather Service said. Some cities will experience temperatures 30 to 50 degrees below average.
To put things in perspective, Atlanta and Nashville, Tennessee, will be colder than Anchorage, Alaska, on Monday.
And by Wednesday, nearly half the nation will shudder in temperatures of zero or lower, forecasters said.
Here's what to expect across the country:
Deep freeze in the Deep South
This isn't a joke. Hard freeze warnings are in effect across much of the Deep South, from eastern Texas to Florida. That includes virtually all of Louisiana until late Monday morning, the National Weather Service said.
The arctic blast threatens to sweep subzero lows as far south as Alabama and plunge much of the Deep South into the single digits.
Unbelievable cold in the Midwest
At this point, even zero degrees sounds balmy.
The afternoon "high" temperatures in parts of the Midwest won't even warm up to zero on Monday, the National Weather Service said.
The extreme weather has prompted school cancellations Monday in St. Louis, Chicago, Detroit, Indianapolis and Milwaukee, Wisconsin.
"It's not just a snow event, it's a cold event, and that's what scares us," Indianapolis Mayor Greg Ballard said. He urged residents to stay off the streets, especially after nightfall.
The Southern Illinois University men's basketball team, fresh off a game against Illinois State, got trapped on the side of Interstate 57 late Sunday and planned to spend the night on the bus.
There wasn't a massive amount of snow on the ground, SIU Athletic Director Mario Moccia said. Rather, it was the blowing snow that made the road virtually impossible to see.
The bus driver decided to pull off the road and get out of the way of traffic until visibility improved. But when the driver tried to get back on the road, there was no traction, and the bus was stuck.
"They're just hanging out, they're watching movies," Moccia said late Sunday night. He said the bus had plenty of fuel, heat and food, and the team was waiting for a tow truck overnight.In Embarrass, Minnesota, residents wondered whether they might see their record-cold temperature of 64 below zero, set in 1996, snap like an icicle.
"I've got a thermometer from the weather service that goes to 100 below," resident Roland Fowler told CNN affiliate KQDS. "If it gets that cold, I don't want to be here.
Travel nightmares
More than 2,000 flights have been canceled within, into or out of the United States for Monday, according to Flightaware.com, which tracks cancellations based on both weather and mechanical problems.
That's on top of the 3,800 flights canceled on Sunday.
John F. Kennedy International Airport in New York was closed briefly Sunday morning after a plane carrying 32 passengers skidded into a snow bank while turning onto a taxiway. No injuries were reported.
No electricity
As if the brutal cold isn't bad enough, tens of thousands of Midwesterners are grappling with no electricity.
More than 15,000 customers in Indiana, 6,800 in Illinois and 2,200 in Missouri didn't have power overnight, according to utility companies.
Chicago opened up 12 centers for residents to seek warmth, one of which was to stay open all night through Tuesday. Libraries and some other city facilities would also be open, said Evelyn Diaz of the city's Department of Family and Support Services. Illinois Gov. Pat Quinn said 100 warming centers were open statewide.
Deadly conditions
The plunging temperatures and wind chill are a dangerous recipe for rapid frostbite or hypothermia.
"Exposed flesh can freeze in as little as five minutes with wind chills colder than 50 below," the National Weather Service's Twin Cities office in Minnesota said.
Over the past week, at least 13 people have died from weather-related conditions.
Eleven people died in road accidents — including one man crushed as he was moving street salt with a forklift.
One man in Wisconsin died of hypothermia. And an elderly woman with Alzheimer's disease in New York state wandered away from her home and was found dead in the snow in a wooded area about 100 yards away.
This, too, shall pass
If there's any good news about the biting cold snap, it's that much of it should be over for the Midwest by Wednesday, the National Weather Service said.
In the meantime, those in the western part of the country can skip all the fuss. Most of the West can expect relatively pleasant weather through Monday.
CNN's Steve Almasy, Dana Ford, George Howell, Todd Borek, AnneClaire Stapleton and Julia Lull contributed to this report.

Columbus Double Murder Suspect Wounded By Police
Columbus police say a double murder suspect was shot and wounded Wednesday by officers near Parsons Avenue and Kossuth Street. He was taken into custody shortly after the killings.
About two dozen people watched the Ohio Democratic debate at an AARP-sponsored event in Columbus.
Many were volunteers with the non-partisan group which is calling on candidates to address two issues in particular – health care and financial security. WOSU's Christina Morgan reports
After the 90-minute discussion, five of the spectators told WOSU the debate had not changed their minds. Connie Wright of Columbus remained undecided, saying she likes both Hillary Clinton and Barack Obama and would like to see them on the same ticket.
Michael Wright favors Barack Obama, but is not opposed to Hillary Clinton. Wright says he can't wait until President George Bush is out of the White House.
Wearing a Barack the Vote button, Ora White said she's talked with a number of African Americans who say Clinton and Obama are the same. She disagrees, saying Obama knows what it is like to work his way up from the bottom.
Upper Arlington resident Earl Goldhammer said he was impressed by both of the Democratic candidates, but says he wanted to hear more about the economy.

This diamond shaped Island is 13 miles from top to bottom and 26 miles across the widest part. It has a laid back atmosphere compared to mainland U.K. and I love it. Visitors come here for the scenary, walks and a touch of Britain 20 years ago. They must love it too as we have the dearest stretch of water, mile for mile, in the world between us and mainland U.K. I live in the east wight between Sandown and Shanklin both renowned for their hours of sunshine.

In studying the antecedents of alliance performance, one stream of research has underscored the alignment between partners' characteristics whereas another has concentrated on relational mechanisms such as mutual trust, relational embeddedness, and relational commitment. We integrate these two perspectives by examining how congruence of the partners' cultures and organizational routines facilitates the emergence of relational mechanisms in non-equity alliances. Our analysis of 420 non-equity alliances in the information technology industry demonstrates how differences in partners' internal task routines undermine relational mechanisms that in turn impact alliance performance. Partners who acknowledge their latent differences can overcome some of these negative consequences. We advance alliance research by studying the performance implications of alliance partners' organizational differences and by demonstrating how these effects are mediated by relational mechanisms.

I'm writing some Java code that depends on some Scala code (that I have also written). Trying to supply an argument with a parameterized type seems to work if the Scala is compiled with 2.8.0 but fail if I use 2.9.1.
The (simplified) Scala code looks roughly like this:
package test
import collection.JavaConversions._
class SomeClass {
def foo(numbers: java.util.Set[Long]) {
This compiles happily with both the 2.8.0 and 2.9.1 compilers. The Java code looks something like this:
package test;
import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;
public class App {
public static void main(String[] args) {
new SomeClass().foo(new HashSet<Long>(Arrays.asList(1L, 2L, 3L)));
If I compile the Scala with the 2.8.0 compiler, then the Java will compile happily (with Java's 1.6.0_26 compiler). However, if I compile the Scala with 2.9.1, then the Java compiler fails with the error:
test\App.java:16: foo(java.util.Set<java.lang.Object>) in test.SomeClass cannot be applied to (java.util.HashSet<java.lang.Long>)
sc.foo(new HashSet<Long>(Arrays.asList(1L, 2L, 3L)));
1 error
So it seems that while Scala 2.8.0 retains in the bytecode the information that
numbers is of type
Set<Long>, the 2.9.1 compiler emits bytecode where
numbers is a
Is this a bug? Is it an unfortunate (for me) side-effect of a deliberate change? (The Scala changelog mentions "various fixes in ...
JavaConversions for smoother interoperation"). If so, is there anything I can do to get this to work with 2.9.1?

Marquette shows signs of offensive progress in Monday's defeat
Nov 26, 2013, 4:00 PM EDT
TEMPE, Ariz. — On the heels of two poor offensive performances, the way in which No. 25 Marquette began its game on Monday night against Arizona State may have led to many Golden Eagle fans thinking the same thought: here we go again. After a Jamil Wilson jumper 12 seconds into the game Marquette missed eight straight shots, leading to the Sun Devils jumping out to a 14-3 lead just over four minutes into the game.
For the half Marquette shot 37.5% from the field, and that combined with some shoddy defense (Arizona State needs to be credited for their work offensively, as well) resulted in the Golden Eagles trailing by 11 at the intermission. In front of a hostile crowd and once again struggling to consistently find quality looks, this was a point when Marquette could have easily succumbed to the pressure.
However Marquette didn't fold, executing much better offensively in the second half and having a chance to send the game to overtime before a Jordan Bachynski block as time expired gave Arizona State the 79-77 victory. Marquette didn't play its best game defensively, as Arizona State shot 53.7% from the field and averaged 1.23 points per possession, but the Golden Eagles' improved offensive performance is certainly a positive to be taken from the first stop on their trip west.
"Four turnovers and as good as we were on the offensive glass, that's good," head coach Buzz Williams said following the defeat. "But it's not good if on the other end, in both halves, they shot 54%."
Marquette finished the game with 18 assists on 28 made baskets, and their turnover percentage (6.3%) was a season-low. And from an efficiency standpoint (120.7 efficiency) this was the Golden Eagles' best offensive performance since their win over Grambling State (140.7), and with all due respect to the Tigers producing at that rate on the road against a team the caliber of Arizona State is an entirely different matter.
Marquette shot just 40.6% from the field, and the field goal percentage likely won't be all that high this season due to their overall lack of shooters. But the Golden Eagles can make up for that on the boards, and they did so against Arizona State by rebounding nearly 40% of their missed shots. Add in good performances from guards Jajuan Johnson (nine points off the bench), Jake Thomas (16 points, five three-pointers) and Derrick Wilson (14 points, seven assists and no turnovers), and there are positives Marquette can take from this game.
It should also be noted that Marquette was without the services of the injured Todd Mayo (ankle), and when he returns to the lineup that another experienced perimeter option for coach Williams to call upon. Expecting this group to be "lights-out" shooters wouldn't be the best thing to do, but Marquette has the activity needed to make up for that in other areas.
The next step is to see whether or not the Golden Eagles can string together solid offensive performances, and this weekend's Wooden Legacy should be a good litmus test in that regard. And while their defense against Arizona State was a major issue, that performance was a departure from what the Golden Eagles do on that end of the floor when comparing it to their loss to Ohio State.
Marquette didn't defend well on Monday night but they still had a shot at leaving Tempe with a win, and for that they can thank their improvement on the offensive end.

This past summer I was fortunate enough to participate in the Harvard Summer School Program, where I was enrolled in the Principles of Economics (ECON S-10AB) course. The experience was rewarding and I walked away from it with a more profound knowledge of the material.
I would like to complement my classroom studies with something more tangible—hands-on research. For this reason, I look forward to having the opportunity to learn from the finest, working side-by-side with a Harvard affiliate.
Kindly contact me at the aforementioned email address to discuss any available openings.

Feeling connected to others is vital to a person's mental well-being, as well as physical health, research at the University of Chicago shows.
The studies, reported in a new book, Loneliness: Human Nature and the Need for Social Connection, show that a sense of rejection or isolation disrupts not only abilities, will power and perseverance, but also key cellular processes deep within the human body.
The findings suggest that chronic loneliness belongs among health risk factors such as smoking, obesity or lack of exercise, according to lead author John Cacioppo, the Tiffany & Margaret Blake Distinguished Service Professor in Psychology at the University.
"Loneliness not only alters behavior, but loneliness is related to greater resistance to blood flow through your cardiovascular system," Cacioppo said.
"Loneliness leads to higher rises in morning levels of the stress hormone cortisol, altered gene expression in immune cells, poorer immune function, higher blood pressure and an increased level of depression.
Loneliness also is related to difficulty getting a deep sleep and a faster progression of Alzheimer's disease, said Cacioppo. He drew on recent research in preparing the book, written with William Patrick, the former science editor at Harvard University Press. The book was just published by W.W. Norton.
One of the founders of a new discipline called social neuroscience, Cacioppo used functional Magnetic Resonance Imaging (fMRI) brain scans and advanced scientific techniques to document the roles of loneliness and social connection as central regulatory mechanisms in human physiology and behavior.
The authors traced the need for connection to its evolutionary roots. In order to survive, humans needed to bond to rear their children. In order to flourish, they needed to extend their altruistic and cooperative impulses beyond narrow self-interest and immediate kin. But in the environment of
