[OT] Password hash cracking
Folks, in Bruce Schneier's latest newsletterhttps://www.schneier.com/crypto-gram-1403.htmlthere is a section at the end where he discusses the vulnerability of passwords. One of the links is to this interesting and frightening article: http://arstechnica.com/security/2013/05/how-crackers-make-minced-meat-out-of-your-passwords/ The hashes in this cracking test were made with plain old MD5, but even ignoring that, it's a sobering reminder of the progress in guessing and cracking hashed passwords. I was surprised to learn that salting the hashes doesn't offer much defence. I was amazed that they were using GPUs for hashing and a graph shows that they're faster than CPUs ... is that possible? After this I think the lessons are: * Schneier suggests you make passwords out of pieces of words and sentences to avoid predictable formats. * Use a more recent and computationally intensive hasher. * Don't let anyone steal your hashes. * Don't store the whole hash (I learned in Russinovich's book that msv1_0http://dll.paretologic.com/detail.php/msv1_0.dll only stores half a user's hash in the registry). *Greg K*
[OT] Noise cancelling earphones for a quiet programming environment?
Hi All So that I can concentrate better, I am trying to filter out the mouse clicking sound from person at the desk next to me. Has anyone any tech recommendations on how to do this? Thanks Kirsten
Re: [OT] Noise cancelling earphones for a quiet programming environment?
Do you know what style earphones you want? In ear, over ear etc? Do you want something with cables or a wireless bluetooth option?

Light weight, over the ear would be best. Cordless would be a nice to have - but i guess that might add battery weight. I called in at Dick Smith and the sales lady said that while there are earphones that cancel out aeroplane sounds she didnt think there were any for mouse clicks. _ From: ozdotnet-boun...@ozdotnet.com [mailto:ozdotnet-boun...@ozdotnet.com] On Behalf Of William Luu Sent: Sunday, 23 March 2014 1:26 PM To: ozDotNet Subject: Re: [OT] Noise cancelling earphones for a quiet programmingenvironment?

Re: [OT] Noise cancelling earphones for a quiet programmingenvironment?
Sorry I do not think I am going to be a lot of help here... Recommendation: The best thing to do is to get out of the open office environment, I find that I am greatly affected by background distractions. I have had five fold productivity increases when working from home or in some other comfortable place away from the mad office. If that fails, I have used Bose QuietComfort(R) 15 Acoustic Noise Cancelling(R) headphones ( http://worldwide.bose.com/axa/en_au/web/quietcomfort_15/page.html) which are great at cancelling out the background road sounds on the bus, but pretty useless at the higher frequency office sounds. See http://en.wikipedia.org/wiki/Talk:Noise-cancelling_headphones#Real-world_performance_of_noise-cancelling_headphonesfor a discussion on this. The best solution is that everyone has a work cubical with a lot of sound deadening material and meetings happen in meeting rooms, not at desks.

Re: [OT] Noise cancelling earphones for a quietprogrammingenvironment?
+1 for the Bose, had them a few years, used in open plan office to good effect for stopping background air con hum etc. but won’t cancel someone having a conversion next to you. Scary think is when you take them off you notice how much ambient background noise there is. Anyone enjoy working in open plan offices? Rather have a separate “war room” where the team sits together??
