Jinja2 and… Powershell? Automation(ish) Microsoft DHCP

Most of us have home labs, right?

I’m in the middle of doing some zero touch provisioning testing, and I had the need to create a bunch of DHCP scopes and reservations, some with scope specific options, and some with client specific options. As often as I’ve had to create a Microsoft DHCP server in the lab and set up some custom scopes, I decided I was going to figure out how to automate this as much as I could with a little effort as possible.

After taking a quick look around for a python library to help me out, python being my weapon of choice, I realized that I was going to have to get into some Powershell scripting. I’ve dabbled before, but I’ve never really take the time to learn much about Powershell control structures ( loops, conditionals, pipes, etc…).  I really didn’t want to spend the time getting up to speed on a new language, so I instead decided I was going to use the python skills I had to auto generate the scripts using a little jinja2 and some google-technician skills.

Figuring out the Powershell Syntax

This was the easy part actually, Microsoft has some pretty Continue reading

On the ‘Net: Big thinkers leave Cisco

The industry is reeling from Monday’s report that four of Cisco’s best-known executives are leaving the company. An internal memo from Cisco CEO Chuck Robbins, first reported by the Wall Street Journal, announced the resignations of Mario Mazzola, Prem Jain, Luca Cafiero and Soni Jiandani, effective June 17. The four formed a team that many referred to as MPLS — letters that represent the initials of their first names. -Channel Partners

On the ‘Net: You keep using that SDN word…

Software Defined Networks (SDNs), are everywhere, and everyone is either building one, selling one, or using one. Everyone, that is, except—probably—you. Don’t feel too bad if you’re feeling left out, because it’s hard to know, precisely, what you’re actually being left out of. After all, can you actually define what an SDN is? -ECI

Big data paper shows stock market trades behave like light bulbs

In the stock market, electronic trading (AKA “etrading”) originally started so people could buy and sell stocks and other financial instruments more easily. No more hanging out on the floor of a stock exchange or calling your orders into your broker; you could do it all from your desktop. This was good because it made markets more accessible and reduced costs.Then, in the 1980’s, because the electronic trading platforms had application programming interfaces to allow new client-side interfaces to be developed, the inevitable happened, the next generation of electronic trading appeared. Algorithmic trading (AKA “algo trading” or “black box trading”) removed humans from the equation and exploded as the latest, greatest stock market money-making strategy. To read this article in full or to leave a comment, please click here

Apple confirms: Pokemon Go has already set an App Store record

Since its release earlier this month, Pokemon Go has become a full-fledged cultural phenomenon. Speaking to this point, the last few weeks have been chock-full of stories involving addicted Pokemon Go players getting themselves into all sorts of ridiculous situations. From a Pokemon Go player who accidentally drove his car into a parked police car to a reporter who was recently caught playing the game during a State Department meeting, it seems as if the entire world is obsessed with capturing virtual monsters on Nintendo's Augmented Reality themed mobile app.To read this article in full or to leave a comment, please click here

More than half the world is still offline

While it may seem like half the world is chasing Pokemon right now, the other half is not even on the Internet.About 3.9 billion people, or 53 percent of the population, will still be offline at the end of this year, the International Telecommunication Union estimates. Even in Europe, the most connected region, 20.9 percent of all people aren’t online. In Africa, the least connected continent, 74.9 percent are offline.Those figures are part of the annual statistical report from the agency, which is part of the United Nations. The report also showed there’s still a huge divide between rich and poor countries, and a growing gap between men and women, when it comes to internet access. It shows that efforts by companies like Google and Facebook to get all people connected could take a long time.To read this article in full or to leave a comment, please click here

Why a Verizon and Yahoo merger would be like Microsoft snapping up CompuServe

Wait, what?If this rumor about Verizon buying Yahoo for $5B is true, we have an honest to goodness schadenfreude moment for me as someone who remembers the days of the Buddy List, giant banner ads (which is actually still common at Yahoo Mail for some reason), and those plastic discs they might still sell at Walmart for gaining “high-speed Internet” access.As you may know, Verizon also owns AOL. Those three letters, combined with the Yahoo exclamation mark, create some vivid memories. Few of them are good ones. I remember having to wait for my modem to connect to AOL back in the day, and for the banner ads at Yahoo.com to finish loading. It’s a curious development, but it makes about as much sense as other luminous icons of tech combining into an ungodly entity driven by brand dominance.To read this article in full or to leave a comment, please click here

AMD mulls a CPU+GPU super-chip in a server reboot

AMD emerged as a serious threat to Intel in servers more than a decade ago, but after a series of missteps and bad chips, the company's server business is hanging on by a thread.Now, AMD is rebooting its server chip business with the upcoming Zen CPU, which will also be used in PCs. AMD is getting creative with Zen and considering merging the CPU with a high-performance GPU to create a mega-chip for high-performance tasks."It's fair to say we do believe we can combine a high-performance CPU with the high-performance GPU," AMD CEO Lisa Su said during an earnings call on Thursday.Su's comment was in response to a question on whether AMD would ultimately combine its Zen CPU with a GPU based on the upcoming Vega architecture into one big chip for enterprise servers and supercomputing.To read this article in full or to leave a comment, please click here

Verizon will cut off unlimited data users who use too much unlimited data

Verizon's continuing its ongoing mission to pare down the number of customers on unlimited data plans by migrating them to ones with hard limits. Recently, the company came up with a way to get rid of its biggest data hogs. Verizon is notifying customers using an “extraordinary” amount of data per month that they must move off their unlimited data plan by August 31. If they don’t switch, the carrier will disconnect their accounts, though they’ll have 50 days to reactivate them on a limited plan, as first reported by Droid Life. Verizon ceased offering unlimited data plans in 2011.To read this article in full or to leave a comment, please click here
