Twitter acquires machine learning startup Whetlab

To boost its in-house machine learning efforts, Twitter has acquired Whetlab, a startup that makes it easier for companies to use machine learning tools.As part of the acquisition, announced Wednesday, Twitter will shut down Whetlab’s beta service on July 15, and will no longer accept sign-ups for the product. Current users will be able to export their data from Whetlabs’s website in either tab-separated format or JSON.It’s not exactly clear how Twitter plans to use Whetlab’s technology to enhance its existing machine learning plans. However, the startup’s tool seems useful for any company implementing machine learning techniques. The technology, which was developed by researchers at Harvard, Toronto and Sherbrooke universities, takes in information about the problem a user wants to solve with machine learning. It then gives the user a series of suggestions to help them optimize a machine learning model to solve the problem.To read this article in full or to leave a comment, please click here

How to rollout a successful new product or service

So you are about to launch a new product or service, or are thinking about it. Congratulations. Unfortunately, having the best idea (or product or service) in the world may not get you buzz, or sales, if the right people don’t know about it. Here are nine steps you can take to increase the odds of your rollout being successful.1. Make sure the product or service works – before you start selling it. Whether your product or service is digital in nature, or you plan on selling it online, first “make sure the app or website is bug-free,” says Mark Tuchscherer, cofounder & president, Geeks Chicago, a Web development company. “We see products launch all the time that companies didn't test thoroughly, and this is the best way to lose potential customers,” he explains. “People have short attention spans and want stuff to work fast. If your application crashes in the first few seconds, you are going to lose a lot of new users.”To read this article in full or to leave a comment, please click here

How would you use Lua scripting in a DNS server?

I'm currently putting Lua into a DNS server, and I'm trying to figure out how people would use it.

A typical application would be load-balancing. How I would do this is to create a background Lua thread that frequently (many times a second) queried an external resource to discover current server utilitzation, then rewrote the RRset for that server to put the least utilized server first. This would technically change the zone, but wouldn't be handled as such (i.e. wouldn't trigger serial number changes, wouldn't trigger notification of slave zones).

Such a thread could be used for zone backends. Right now, DNS servers support complex backends like SQL servers and LDAP servers. Instead of making the server code complex, this could easily be done with a Lua thread, that regularly scans an SQL/LDAP server for changes and updates the zone in memory with the changes.

Both these examples are updating static information. One possible alternative is to execute a Lua script on each and every DNS query, such as adding a resource record to a zone that would look like this:

*.foo.example.com. TXT $LUA:my_script

Every query would cause the script to be executed. There are some Continue reading

FCC to smack AT&T with $100M fine for choking “unlimited” data plan speeds

The Federal Communications Commission said it plans to fine AT&T Mobility $100M – the agency’s largest fine ever -- for severely slowing down data speeds for customers with unlimited data plans. The FCC’s investigation revealed that millions of AT&T customers were slowed for an average of 12 days per billing cycle, significantly impeding their ability to use common data applications such as GPS mapping or streaming video. And the company failed to adequately notify its customers that they could receive speeds slower than the normal network speeds AT&T advertised, the FCC stated.To read this article in full or to leave a comment, please click here

FCC plans to fine AT&T $100 million over ‘unlimited’ data plans

The Federal Communications Commission plans to fine AT&T $100 million for misleading customers by throttling speeds on the lines of millions of customers who had "unlimited" data plans.The FCC alleges that AT&T did not adequately disclose to its customers on "unlimited" data plans that their speed would slow drastically after they had reached a monthly data allowance of 5GBs. The policy began in 2011.Data speeds were significantly slowed to 512kbps from the advertised 5Gbps to 12Gbps under something AT&T called its maximum bit rate policy. That very name is clearly at odds with an unlimited plan, a senior FCC official told reporters on a conference call.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Speedier 5.4-Gigabit Wi-Fi routers coming this year

It seems like I was only just writing about the new, up-to-3.2 Gbps Wi-Fi routers, such as the drone look-alike D-Link DIR-890L.In fact, it was all of six-months ago, in my post, "Is it time to move to beamforming 802.11ac?"Well, that generation of wireless networking gear using beamforming and combining multiple bands, is about to be superseded. Microprocessor-maker Broadcom has launched new 5.4 Gbps-capable chips that will appear in routers later this year.To read this article in full or to leave a comment, please click here

Multi-datacenter Firewall Policy Automation

secdevops

Back in that world where I reinvent the commercially available wheel, I’ve been wondering for a while about how to automate the creation of firewall policies in a multi-datacenter environment. This week I started tinkering with possible ways to achieve this, and knocked up some proof of concept code in my favorite untrendy, archaic language, Perl. Don’t say it.

The key issue is that given a firewall request (source IP, destination IP, port) it’s necessary to identify the firewalls and zones to which those rules apply, in order that rules can be automatically built in the right place(s). An additional twist I’ve seen is firewalls that have multiple routing instances, each of which maintains its own set of zones, effectively isolated from each other, even though they’re all on the same firewall.

Graphing Firewalls

I spent a while thinking about ways to model the firewall architecture, and kept on getting caught up on the firewalls with multiple routing instances. Because of the routing isolation, they behave like two separate firewalls, which makes it a little tricky to figure out the correct paths. I also wanted a solution that might also tell me which specific firewall zones were involved in the path; Continue reading
