New research: There’s no need to panic over factorable keys–just mind your Ps and Qs
We have been able to remotely compromise about 0.4% of all the public keys used for SSL web site security. The keys we were able to compromise were generated incorrectly–using predictable “random” numbers that were sometimes repeated. There were two kinds of problems: keys that were generated with predictable randomness, and a subset of these, where the lack of randomness allows a remote attacker to efficiently factor the public key and obtain the private key. With the private key, an attacker can impersonate a web site or possibly decrypt encrypted traffic to that web site. We’ve developed a tool that can factor these keys and give us the private keys to all the hosts vulnerable to this attack on the Internet in only a few hours.
The last time I was at this blog was many years ago when he showed how to hack electronic voting machines.
Digital Exams on the iPad
Firstly, take an iPad and restore it to factory settings. We used spare iPads for this but you could equally back up and erase the pupil’s own iPad for the duration of the exams.
Next, install PDF Expert from the App Store.

Move to mobile will bring big changes for Linux
This may present some messaging problems for the big commercial Linux vendors, by the way: if the distribution underneath becomes less important, then Red Hat Enterprise Linux RHEL and SUSE Enterprise Linux Server may soon have a serious fight on their hands. In the past, one of the big differentiators has been that these “big” distros provide solid infrastructures in which business applications can be developed. If this Linux-is-Linux-is-Linux idea takes root, that will undercut a big marketing tool for Red Hat and SUSE Linux.
via Move to mobile will bring big changes for Linux | ITworld.
But I don’t think that’s going to last. The Linux community may be cocky now, but let’s think through this Linux-is-everywhere scenario a bit. If the operating system becomes just a background component that runs more web than native apps and app development for the platform itself becomes de-emphasized, then the obvious question then becomes: what does it matter it it’s Linux running on the operating system layer?
You still need a reliable OS to run the web servers which is the space RHEL and SUSE enterprise sell into.

Under the hood: OpenSIPs and FreeSWITCH
So if we say OpenSIPs is the load balancer that directs traffic (call flow) along the road which is the Internet…where does all that traffic get directed towards? You guessed it. FreeSWITCH.
FreeSWITCH is a media server. Think of a media server as being similar to a language translator between two people who speak two completely different languages. In its simplest form, a media server takes audio from one person, processes it, and passes it on to another person. It also provides translation services, meaning if one person “talks” another language it can convert that language on the fly to something the other party can understand.

$30/year to backup app data. I wonder if cloud to cloud stuff will soon take on the acronym c2c. AFAIK, this only backs up google apps. What about other apps?
Service Location Protocol
Service Location Protocol – Wikipedia, the free encyclopedia.
The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks. It has been defined in RFC 2608 and RFC 3224 as Standards Track document.
