Maria discovered that one of the feature films is Dreamcatcher, a documentary about human trafficking. Given our lab?s active involvement in fighting human trafficking, we would like to invite you all for an evening out at the movies. Please answer the following poll if you are interested in attending and if you would like to bring a +1 so that we can organize tickets. There will also be a special appearance and Panel/Q & A with Brenda Myers-Powell, Co-Founder and Executive Director of the Dreamcatcher Foundation. http://goo.gl/forms/CrqD86ohEt Dreamcatcher (UK/USA, 2015, 97 min) FRIDAY, MARCH 18 7:00 pm | McConomy Auditorium, CMU University Center + Special Appearance and Panel/Q & A with Brenda Myers-Powell, Co-Founder and Executive Director of the Dreamcatcher Foundation +Dessert Reception =============================== Benedikt Boecking Research Programmer Auton Lab, School of Computer Science Carnegie Mellon University -------------- next part -------------- An HTML attachment was scrubbed...

Well I just built it myself and tested it including pycaffe and matcaffe (MATLAB interface). I have not built cudnn. You will have to register and build it yourself. The binaries are located in /opt/caffe/build/tools If you get an error that CUDA Libraries are not available you will need to set explicitly LD_LIBRARY_PATH variable in your shell profile. The same goes for binaries itself. Please adjust your shell profiles accordingly (no hand-holding this time). My "official" version of Caffe is built using ATLAS library. Already mentioned tutorials explain why we used ATLAS. It is also possible to build it using Open-BLAS. Please no complains about this choice. You can build in your directory whatever you fancy. I also played with Caffe myself little bit. That thing requires serious reading of documentation before you can do anything with it even if you are an expert in machine learning. If you come to my office for help you will be quizzed on existing documentation before getting any help :) Cheers, Predrag From predragp at cs.cmu.edu Wed Mar 2 10:48:44 2016 From: predragp at cs.cmu.edu (Predrag Punosevac) Date: Wed, 02 Mar 2016 10:48:44 -0500 Subject: LibreSSL not affected by DROWN attack Message-ID: <20160302154844.-J4FcZ2GI%predragp@cs.cmu.edu> Dear Autonians, This is a pre-emptive as I am sure some of you would e-mail me as the news about OpenSSL DROWN attack trickle down to user community. Our perimeter firewall are largely unaffected by this exploit since we are running or in the process of upgrading to the latest OpenBSD which doesn't even use OpenSSL but rather its own 50% smaller version of LibreSSL. I am considering switching our desktops from OpenVPN to L2PT/IPSec as OpenVPN indeed heavily relies on OpenSSL and Linux specific stuff and is indeed the "unsafest" part of our network. Finally people who should be really concern about this are https users who use SSLv2 (I am also in the process of switching our nginx proxies to relayd for that very reason as the second one uses LibreSSL). SSLv2 protocol is obsolete and should not be used. LibreSSL doesn't even have a support for it anymore. Also current versions of OpenSSH contain no OpenSSL related code.

It looks like we will have the main character present in the room in person. 4. Those of us who are involved in anti-trafficking research sometimes feel frustrated upon realization that relatively little is being done to support victims pulled from circulation by law enforcement, and how many of them return to the old business after being rescued. We have imagined better effectiveness of rescue. This movie and the presence of one of the survivors gives us a chance to improve understanding of these issues. Recall that our original intention behind Traffic Jam was helping the victims. Our current technology supports law enforcement and it clearly leads towards that goal, but somewhat less directly than we have imagined. Could more be done?

These are our five largest CPU computing nodes. I hate to name the names but here it comes. His name is Ankit Laddha and he did that by running the 30 instances of the same script across the five machines which caused original problems yesterday. I thought I was clear in my earlier message that we had only temporary fix for the electricity problem. Let me now give you the full explanation. We have old 20 A PDU plugged into 15 A 120V UPS. Dr. Barnabas has just purchased 20A 208V PDU. However we will need now to purchase 208V 20A UPS listed here for $1500 http://www.apc.com/shop/us/en/products/APC-Smart-UPS-3000VA-RM-2U-LCD-208V/P-SMT3000RMT2U Unfortunately I didn't check my notes before the purchase and wishfully assumed that the UPS donated to us couple of months ago was 208V (which is the new standard). It is not. It is an old 15A 120V UPS. So until the new UPS is purchased we will have to be little bit more careful how we conduct ourselves now when we know that the circuit can be reproducibly crashed by large CPU loads. Mr. Laddha has a yellow card now and if he breaks the circuit again I will have no other option but to temporary suspend his lab account.

I am running a centralized logging server using syslog-ng from the ports. The way I read your e-mail is that I will no longer be able to log messages using syslog-ng from the local host but the port will continue to work as expected. Would I be able to run syslogd for the local host and syslog-ng for remote hosts simultaneously? IIRC I saw people posting on misc who were doing that in the past but I think when I played with it syslog-ng didn't want to start until I turned off syslogd. How suitable is syslogd from the base as a centralized logging server. I know that it supports TCP and TLS now but does it play well with rsyslog or syslog-ng? I have bunch of Linux servers to log.
