Datiphy monitors database transactions to look for potentially malicious behavior. It builds a baseline of normal activity, and alerts if it detects deviations.
The post Startup Radar: Datiphy Watches For Database Dangers appeared first on Packet Pushers.
these rules prohibit one group of companies (ISPs) from charging another group of companies (content companies) the full cost for using their servicesUh, no, that's how Democrats frame the debate. ISPs charging content providers is actually a very bad thing. That we Republicans oppose NetNeutrality is not based on the belief that "charging content companies" is a good thing.
CENX answers post-webinar questions on data services delivery and full services lifecycle orchestration through lifecycle services orchestration (LSO).
AT&T spells out some specific vendor contributions, including vCPEs and virtual routers.
The startup uses public clouds and virtual routers to speed Internet traffic.
When nanoseconds matter you have to pay attention to OS scheduling details. Mark Price, who works in the rarified high performance environment of high finance, shows how in his excellent article on Reducing system jitter.
For a tuning example he uses the famous Disrupter inter-thread messaging library. The goal is to keep the OS continuously feeding CPUs work from high priority threads. His baseline test shows the fastest message is sent in 76 nanoseconds, 1 in 100 messages took longer than 2 milliseconds, and the longest delay was 11 milliseconds.
The next section of the article shows in loving detail how to bring those latencies lower and more consistent, a job many people will need to do in practice. You'll want to read the article for a full explanation, including how to use perf_events and HdrHistogram. It's really great at showing the process, but in short:
Found this link very useful doing this:

Some useful commands:
Display a certificate:
openssl x509 -in test-cert-top.pem -noout -text
Display a certificate's issuer:
openssl x509 -in test-cert-top.pem -noout -issuer
Display a certificate's subject:
openssl x509 -in test-cert-top.pem -noout -subject
Verify a certificate:
openssl verify test-cert-top.pem
Verify a certificate chain with 3 certificates:
openssl verify -CAfile test-cert-bottom.pem -untrusted test-cert-middle.pem test-cert-top.pem
-CAfile keyword indicates which certificate is used as the root certificate, with the -untrusted option being set to validate the intermediate certificate in the chain
Verify a certificate chain with 2 certificates:
openssl verify -CAfile test-cert-bottom.pem test-cert-middle.pem
The next OpenStack Summit is quickly approaching -- and the schedule is, as always, packed with great sessions, collaboration days, social events, get-togethers, and more.
If you’re joining the event in Tokyo, which runs from October 27-30, and you’re a fan of Ansible, you just might be thinking to yourself… “If only there was a playbook for this!”
Behold! My amazing psychic capabilities alerted me to this exact scenario. Okay, not really, but: in, ahem, "playbook-inspired" format, you’ll find a list of tasks for each type of role -- conference sessions, OpenStack projects using Ansible to know about, the Ansible Collaboration Day onsite at Summit, and how to stay up to date with Ansible-related happenings on-site and beforehand.
Not familiar with Ansible yet, or how it works with OpenStack? Here's the great news: There will be plenty of opportunities for you to learn all about it at OpenStack Summit. And just like Ansible makes it easy for you to deploy and operate your OpenStack cloud -- this blog post makes it easy for you to find the Ansible-related content to get you started on your path to Ansible+OpenStack cloud bliss.
All you have to do is decide which Continue reading
