Xperia Z4 launch reflects Sony’s timidity in smartphones

Sony’s decision to launch its new high-end smartphone, the Xperia Z4, only in Japan, shows its hesitancy about this market and puts into question its commitment to it.Monday’s introduction of the Xperia Z4 stands in stark contrast to the arrival of competing products like the HTC One M9 or the Galaxy S6 and S6 edge from Samsung Electronics, which were launched with much fanfare at Mobile World Congress. And when LG premiers the G4 on April 28, it will do so at events around the world.But considering the very challenging position Sony’s smartphone business has found itself in, the low-key unveiling doesn’t come as a shock.To read this article in full or to leave a comment, please click here

Improving Mean Time To Innocence With ThousandEyes

In the case of troubleshooting poor performance for an off-site application, improving mean time to innocence is really important. Businesses need to understand whether the problem is in the local infrastructure, in the remote cloud, or somewhere in the middle. This is not especially easy to track down by hand. Manual traceroutes, simple ping tests, and DNS resolution checks are most of what can be done with the average workstation, but in fact there is a great deal more information that is publicly accessible.

The facts, while interesting, are irrelevant

Maybe my excuse should be that it was somewhere around two in the morning. Or maybe it was just unclear thinking, and that was that. Sgt P. and I were called out to fix the AN/FPS-77 RADAR system just at the end of our day (I normally came into the shop around 6:30AM after swimming a mile in the Ft. Dix pool, showering, and eating breakfast, so I truly had an early start), so we’d been fighting this problem for some seven or eight hours already. For some reason, a particular fuse down in the high voltage power supply kept blowing. Given this is the circuit that fed the magnetron with 250,000 volts at around 10 amps (yes, that’s a lot of power, especially for a device originally built in 1964), it made for some interesting discussion with the folks in base weather, who were thus dependent on surrounding weather RADAR systems to continue flight operations.

They weren’t happy.

We traced the problem back, using our best half splitting skills in a high voltage circuit that took minutes to power up and down, and finally decided it was a particular resistor located over on a corner of one assembly (we Continue reading

The Future of the Distributed Network

Back in December of 2014, I wrote a blog post about the complexities of the network as a distributed system. In it I pointed out that networks have traditionally been built as distributed systems, and that our entire management and knowledge base for networks is based on this. But, is this the best approach for current and future networking needs?

As humans we have our own ideas of how to best solve problems. While we are immensely creative, our solutions aren’t always the best (or will never be). We often look to nature as a guide for how to improve our manmade solutions. When we look at how large complex systems in nature have been created and evolved, perhaps we should look no further than ourselves. The human body is possibly one of the most complex systems we know. If we think of the brain as the centralized control system, it is easy to see that we are, in fact, highly centralized beings.

We live and function, however, in a social environment that has no clearly established central control system. We are organized by different permanent and temporary control systems. We create environments with centralized direction of work to be Continue reading

Twitter accounts outside of the US now fall under EU data protection rules

Twitter revised its privacy policy over the weekend, changing where it handles the account information of users outside the U.S. and clarifying some points.As of Saturday, account information for Twitter users outside the U.S. is handled by Twitter International in Dublin, Ireland. This means that all account information will be subject to Irish privacy and data protection law, which is based on the European Union’s Data Protection Directive, Twitter said on its site.The accounts of U.S. users will still be handled by Twitter’s head office in San Francisco under U.S. law.Dublin is popular with U.S. tech companies, which often base their international and EU operations there. The country’s favorable corporation tax regime is often seen as a reason for IT companies to settle there—as is the small staff of its privacy regulator, which has a staff of just 29 to tackle domestic and international companies.To read this article in full or to leave a comment, please click here

Junos export policy not working?

During a project recently, I was promptly reminded about the construction of Junos route export (i.e. route redistribution) policies. Specifically when filtering prefixes during the export/redistribution. The logic goes something like this:

a) Create prefix-list of prefixes to export
b) Create policy which references the protocol and prefix list to export
c) Attach policy to protocol

An example is here:

policy-options {
    prefix-list CUST_A {
        192.0.2.1/32;
    }

	policy-statement REDISTRIBUTE_STATICS_CUST_A {
    	/* FROM PREFIX-LIST TEST TO METRIC TYPE 1 FOR CUST A */
    	term 1 {
        	from {
            	prefix-list CUST_A;
        	}
        	to protocol ospf2;
        	then {
            	external {
                	type 1;
            	}
            	accept;
        	}
    	}
	}
}

protocols {
	ospf {
		export REDISTRIBUTE_STATICS_CUST_A
		area 0.0.0.0 {
		interface x-x/x/x.x
		}
	}
}

With Junos export policies for routing, if you want to export more prefixes of the same type, adding an additional policy which also references the same protocol for the export will just not work. If you do the below, then you’re out of luck.

policy-options {
    prefix-list CUST_A {
        192.0.2.1/32;
    }

    prefix-list CUST_B {
        192.0.2.2/32;
    }

	policy-statement REDISTRIBUTE_STATICS_CUST_A {
    	/* FROM PREFIX-LIST TEST TO METRIC TYPE 1  Continue reading

Russian hackers uses Flash, Windows zero-day flaws

A fresh attack by a long-known hacking group suspected to be linked with Russia did little to mask its activity in an attack a week ago.The computer security firm FireEye wrote on Saturday that the group—called APT 28—attacked an “international government entity” on April 13, using two recently disclosed software flaws, one of which has not been patched.The attack sought to trick victims into clicking on a link that led to a website which attacked their computer. It first used a vulnerability in Adobe Systems’ Flash player, CVE-2015-3043, then used a still unpatched Microsoft vulnerability, CVE-2015-1701, to gain higher privileges on a computer.To read this article in full or to leave a comment, please click here
