Marc Andreessen Which is why he has invested $25m into Californian startup Samsara, which is the first of a new generation of "internet of things" devices that solves huge industrial problems, rather than turning your fridge or your toothbrush into a portal to the web. "This second wave of companies, they don’t want to just do "internet of things"," Andreessen said.
"They are showing up three years later, saying ok I know exactly how this is going to get used. It’s for real businesses in industrial environments. " Gartner backs this claim - it predicts that businesses alone will double spending on internet of things units by 2020, going from $767 billion to more than $1.4 trillion. Other startups in the space include San Francisco-based Helium, which has raised $16m from investors like Khosla Ventures and Ayla which has raised more than $25m from the likes of Cisco.

First-Hop Redundancy Configuration The HA design in the DSM consists of running two of each switches (applicable in the distribution, core, and data center aggregation layers) and ensuring that the IPv4 and IPv6 routing configurations are tuned and completely fault-tolerant. All distribution pairs in the reference campus configuration are running HSRP for both IPv4 and IPv6. Optionally, GLBP can be used.
HSRP is defined on a per-interface basis and is mostly configured like HSRP for IPv4. The configuration in Example 6-13 shows both HSRP for IPv4 and IPv6 for comparison. When configuring a standby virtual IPv6 address, there are two options: a manually defined link-local address (FE80::/10 prefix) or autoconfig. Both HSRP IPv4 and IPv6 are using lowered hello timers for faster failover as well as adjusted priority values to establish an active/standby role between the 6k-dist-1 and 6k-dist-2 switches. Example 6-13 6k-dist-1 HSRP Configuration QoS Configuration Multicast Configuration.

How to GitHub: Fork, Branch, Track, Squash and Pull Request.
This guide will teach you how to properly contribute to open source projects on GitHub. It assumes that you already know about how to use Git for version control and that you already have a GitHub account. Psstt.. if you already have a GitHub account and you want to earn more money, sign up for Gun.io with your GitHub profile and we'll pair you with people looking for developers based on your portfolio! Getting Started GitHub displays these instructions when you start a new project. GitHub is pretty great about giving advice to users starting new repositories, but it isn't very helpful when it comes to contributing changes back to other projects.
Hopefully, this guide will help. Before you get started, find the page of the project you're looking to improve. Check the Network The network graph. The first thing to do is check the Network tab on the project to see all the other forks that other people have made. Opening an Issue You've got issues, man. Next, head over to the Issues tab.

If you would like to read the other parts in this article series please go to: Introduction In Parts 1 through 4 of this series, we took a look at the evolution of the concept of “identity,” misconceptions about identity in the IT world, and some current identity management solutions, with a focus on digital signatures. We also looked at the criteria for choosing a comprehensive identity management solution for an organization or a federated identity management solution.
In this, part 5, we’ll discuss the future of identity management with a special focus on the effect of the cloud on IDM. Official online IDs Way back in part 1, we discussed the problem of credibility when it comes to identification credentials. Unless the party that issues the credentials is trust-worthy, those credentials are meaningless. In the offline world, the most credence is generally given to IDs that are issued by the government. It is likely that such a system would be voluntary – at first. Identity in the cloud. What You Don’t Know Can Hurt You: LAN Manager Might Be Supported. In this article the author gives a best practice walk through on how to set Active Directory, AD, domain, OU, Group Policy, LAN Manager, NTLMv2, authentication, protocol, SAMup your domain, organizational units, and Group Policy settings correctly. Introduction I have been preaching and teaching about the finer points of authentication protocols, anonymous, group membership, etc. for years. I have been talking about how these simple aspects of your overall Active Directory, overall domain, and server security are essential.
Well, after a brief demo last week at a conference, I am here to tell you, again, to be concerned. There are so many security vulnerabilities that you don’t think are important on a day to day basis, but the hackers of the world are exploiting these areas every day. LAN Manager Defaults for Active Directory There are two areas that your Active Directory domains (as well as local SAM) are affected with regard to LAN Manager. Summary. Videos. Q1 Labs.

Robustness principle. In computing, the robustness principle is a general design guideline for software: Be conservative in what you do, be liberal in what you accept from others (often reworded as "Be conservative in what you send, be liberal in what you accept"). The principle is also known as Postel's law, after Internet pioneer Jon Postel, who wrote in an early specification of the Transmission Control Protocol that:[1] TCP implementations should follow a general principle of robustness: be conservative in what you do, be liberal in what you accept from others.
In other words, code that sends commands or data to other machines (or to other programs on the same machine) should conform completely to the specifications, but code that receives input should accept non-conformant input as long as the meaning is clear. Interpretation[edit] References[edit] External links[edit] Fork (operating system) In Unix systems equipped with virtual memory support (practically all modern variants), the fork operation creates a separate address space for the child.
The child process has an exact copy of all the memory segments of the parent process, though if copy-on-write semantics are implemented, the physical memory need not be actually copied. Instead, virtual memory pages in both processes may refer to the same pages of physical memory until one of them writes to such a page: then it is copied. This optimization is important in the common case where fork is used in conjunction with exec to execute a new program: typically, the child process performs only a small set of actions before it ceases execution of its program in favour of the program to be started, and it requires very few, if any, of its parent's data structures.
When a process calls fork, it is deemed the parent process, and the newly created process, its child. Chapter 15. Nmap Reference Guide. Nmap (“Network Mapper”) is an open source tool for network exploration and security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts.
Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. While Nmap is commonly used for security audits, many systems and network administrators find it useful for routine tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.
The output from Nmap is a list of scanned targets, with supplemental information on each depending on the options used. Key among that information is the “interesting ports table”. That table lists the port number and protocol, service name, and state. Example 15.1. Top 5 Wireless Tools. Derkeiler.
