Catalyst at SXSW 2013: Mentorship and Meaningfulness

Posted by in Development, SoftLayer, Startup Series

In the Community Development group, our mission is simple: Create the industry’s most substantially helpful startup program that assists participants in a MEANINGFUL way. Meaningfulness is a subjective goal, but when it comes to fueling new businesses, numbers and statistics can’t tell the whole story. Sure, we could run Catalyst like some of the other startup programs in the infrastructure world and gauge our success off of the number of partners using the hosting credits we provide, but if we only focused on hosting credits, we’d be leaving a significant opportunity on the table.

SoftLayer is able to offer the entrepreneurial community so much more than cloud computing instances and powerful servers. As a startup ourselves not so long ago, our team knows all about the difficulties of being an entrepreneur, and now that we’re able to give back to the startup community, we want to share battle stories and lessons learned. Mentorship is one of the most valuable commodities for entrepreneurs and business founders, and SoftLayer’s mentors are in a unique position to provide feedback about everything from infrastructure planning to hiring your first employees to engaging with your board of advisors to negotiating better terms on a round of funding.

The Catalyst team engages in these kinds discussions with our clients every day, and we’ve had some pretty remarkable success. When we better understand a client’s business, we can provide better feedback and insight into the infrastructure that will help that business succeed. In other words, we build meaningful relationships with our Catalyst clients, and as a result, those clients are able to more efficiently leverage the hosting credits we provide them.

The distinction between Catalyst and other startup programs in the hosting industry has never been so apparent than after South by Southwest (SXSW) in Austin this year. I had the opportunity to meet with entrepreneurs, investors, and industry experts who have been thirsting for a program like Catalyst for years, and when they hear about what we’re doing, they know they’ve found their oasis. I had a chance to sit down with Paul Ford in the Catalyst Startup Lounge at SXSW to talk about the program and some of the insights and feedback we’d gotten at the show:

Paul was quick to point out that being a leader in the startup community has more impact when you provide the best technology and pair that with a team that can deliver for startups what they need: meaningful support.

Later, I had an impromptu coffee with one of the world’s largest, most prestigious Silicon Valley-based venture capital firms — probably THE most respected venture capital firm in the world, actually. As we chatted about the firm’s seed-funding practices, the investment partner told me, “There is no better insurance policy for an infrastructure company than what SoftLayer is doing to ensure success for its startup clients.” And I thought that was a pretty telling insight.

That simple sentence drove home the point that success in a program like Catalyst is not guaranteed by a particular technology, no matter how innovative or industry-leading that technology may be. Success comes from creating value BEYOND that technology, and when I sat down with George Karidis, he shared a few insights how the Catalyst vision came to be along with how the program has evolved to what it is today:

Catalyst is special. The relationships we build with entrepreneurs are meaningful. We’ve made commitments to have the talented brainpower within our own walls to be accessible to the community already. After SXSW, I knew I didn’t have to compare what we were doing from what other programs are doing because that would be like comparing apples and some other fruit that doesn’t do nearly as much for you as apples do.

I was told once on the campaign trail for President Clinton in ’96 that so long as you have a rock-solid strategy, you cannot be beaten if you continue to execute on that strategy. Execute, Execute, Execute. If you waiver and react to the competition, you’re dead in the water. With that in mind, we’re going to keep executing on our strategy of being available to our Catalyst clients and actively helping them solve their problems. The only question that remains is this:

How can we help you?

Plivo: Tech Partner Spotlight

Posted by in Partner Marketplace, SoftLayer

We invite each of our featured SoftLayer Tech Marketplace Partners to contribute a guest post to the SoftLayer Blog, and this week, we’re happy to welcome Mike Lauricella from Plivo. Plivo is an open communications and messaging platform with advanced features, simple APIs, easy management and volume pricing.

Company Website: http://www.plivo.com/
Tech Partners Marketplace: http://www.softlayer.com/marketplace/plivo

Bridging the Gap Between the Web and Telephony

Businesses face a fundamental challenge in the worlds of telephony and messaging: Those worlds move too slowly, require too much telecom knowledge and take too long to adopt. As a result, developers often forgo phone and SMS functionality in their applications because the learning curves are so steep, and the dated architecture seems like a foreign language. Over the last twenty years, the web has evolved a lot faster than telephony, and that momentum only widens the gap between the “old” telecom world and the “new” Internet world. Plivo was created to bridge that gap and make telephony easy for developers to understand and incorporate into their applications with simple tools and APIs.

I could bore you to tears by describing the ins and outs of what we’ve learned about telephony and telecom since Plivo was founded, but I’d rather show off some of the noteworthy ways our customers have incorporated Plivo in their own businesses. After all, seeing those real-world applications is much more revealing about what Plivo does than any description of the nuts and bolts of our platform, right?

Conferencing Solution
The purest use-cases for Plivo are when our customers can simply leverage powerful telephony functionality. A perfect example is a conferencing solution one of our customers created to host large-scale conferences with up to 200 participants. The company integrated the solution into their product and CRM so that sales reps and customers could jump on conference calls quickly. With that integration, the executive management team can keep track of all kinds of information about the calls … whether they’re looking to find which calls resulted in closed sales or they just want to see the average duration of a conference call for a given time frame.

Call Tracking
Beyond facilitate conference calls quickly and seamlessly, many businesses have started using Plivo’s integration to incorporate call tracking statistics in their environments. Call tracking is big business because information about who called what number, when they called, how long they talked and the result of the call (sale, no sale, follow up) can determine whether the appropriate interaction has taken place with prospects or customers.

Two Factor Authentication
With ever-increasing concerns about security online, we’ve seen a huge uptick in developers that come to Plivo for help with two factor authentication for web services. To ensure that a new site registrant is a real person who has provided a valid phone number (to help cut down on potential fraud), they use Plivo to send text messages with verification codes to those new registrant.

Mass Alert Messaging
Because emergencies can happen at any time, our customers have enlisted Plivo’s functionality to send out mass alerts via phone calls and SMS messages when their customers are affected by an issue and need to be contacted. These voice and text messages can be sent quickly and easily with our automated tools, and while no one ever wants to deal with an emergency, having a solid communication lifeline provides some peace of mind.

WebRTC
An emerging new standard for communications is WebRTC — open project that enables web browsers with Real-Time Communications (RTC) capabilities. WebRTC make communications a feature of the Web without plugins or complex SIP clients. Plivo already supports WebRTC, and even though the project is relatively young, it’s already being used in some amazing applications.

These use-cases are only the tip of the iceberg when it comes to how our customers are innovating on our platform, but I hope it helps paint a picture of the kinds of functionality Plivo enables simply and quickly. If you’ve been itching to incorporate telephony into your application, before you spending hours of your life poring over complex telecom architecture requirements, head over to plivo.com to see how easy we can make your life. We offer free developer accounts where you can start to make calls to other Plivo users and other SIP endpoints immediately, and we’d love to chat with you about how you can leverage Plivo to make your applications communicate.

If you have any questions, feel free to drop us a note at hello@plivo.com, and we’ll get back to you with answers.

SoftLayer Mobile: Now a Universal iOS Application

Posted by in Development, SoftLayer

Last month, we put SoftLayer Mobile HD out to pasture. That iPad-specific application performed amazingly, and we got a lot of great feedback from our customers, so we doubled-down on our efforts to support iPad users by merging SoftLayer Mobile HD functionality with our standard SoftLayer Mobile app to provide a singular, universal application for all iOS devices.

By merging our two iOS applications into a single, universal app, we can provide better feature parity, maintain coherent architecture and increase code reuse and maintainability because we’re only working with a single feature-rich binary app that provides a consistent user experience on the iPhone and the iPad at the same. Obviously, this meant we had to retool much of the legacy iPhone-specific SoftLayer Mobile app in order to provide the same device-specific functionality we had for the iPad in SoftLayer Mobile HD, but I was surprised at how straightforward that process ended up being. I thought I’d share a few of the resources iOS includes that simplify the process of creating a universal iOS application.

iOS supports development of universal applications via device-specific resource loading and device-specific runtime checks, and we leveraged those tools based on particular situations in our code base.

Device-specific resource loading allows iOS to choose the appropriate resource for the device being used. For example, if we have two different versions of an image called SoftLayerOnBlack.png to fit either an iPhone or an iPad, we simply call one SoftLayerOnBlack~iphone.png and call the other one SoftLayerOnBlack~ipad.png. With those two images in our application bundle, we let the system choose which image to use with a simple line of code:

UIImage* image = [UIImage imageNamed: @"SoftLayerOnBlack.png"];

In addition to device-specific resource loading, iOS also included device-specific runtime checks. With these runtime checks, we’re able to create conditional code paths depending on the underlying device type:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    // The device is an iPad running iOS 3.2 or later.
} else {
    // The device is an iPhone or iPod touch.
}

These building blocks allow for a great deal of flexibility when it comes to creating a universal iOS application. Both techniques enable simple support based on what device is running the application, but they’re used in subtly different ways. With those device-specific tools, developers are able to approach their universal applications in a couple of distinct ways:

Device-Dependent View Controller:
If we want users on the iPhone and iPad applications to have the same functionality but have the presentation tailored to their specific devices, we would create separate iPhone and iPad view controllers. For example, let’s look at how our Object Storage browser appears on the iPhone and the iPad in SoftLayer Mobile:

Object Storage - iPhoneObject Storage - iPad

We want to take advantage of the additional real estate the iPad provides, so at runtime, the appropriate view controller is be selected based on the devices’ UI context. The technique would look a little like this:

@implementation SLMenuController
...
 
- (void) navigateToStorageModule: (id) sender {
	UIViewController<SLApplicationModule> *storageModule = nil;
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        storageModule = [SLStorageModule_iPad storageModule];
    } else {
        storageModule = [SLStorageModule storageModule];
    }
    [self navigateToModule: storageModule];
}	
...
@end

“Universal” View Controller
In other situations, we didn’t need for the viewing experience to differ between the iPhone and the iPad, so we used a single view controller for all devices. We don’t compromise the user experience or presentation of data because the view controller either re-scales or reconfigures the layout at runtime based on screen size. Take a look at the “About” module on the iPhone and iPad:

About Module - iPhoneAbout Module - iPad

The code for the universal view controller of the “About” module looks something like this:

@implementation SLAboutModuleNavigationViewController
…
 
- (id) init {
    self = [super init];
    if (self) {
      _navigationHidden = YES;
		_navigationWidth = [[UIScreen mainScreen] bounds].size.width * 0.5;
    }
    return self;
}@end

There are plenty of other iOS features and tricks in the universal SoftLayer Mobile app. If you’ve got a SoftLayer account and an iOS devices, download the app to try it out and let us know what you think. If you were a SoftLayer Mobile HD user, do you notice any significant changes in the new app from the legacy app?

Should My Startup Join an Accelerator/Incubator Program?

Posted by in Business, Executive Blog, SoftLayer, Startup Series

As part of my role at SoftLayer, I have the opportunity and privilege to mentor numerous entrepreneurs and startup teams when they partner with us through our Catalyst program. One question I hear often is, “Should I join an accelerator?” My answer: “That all depends.” Let’s look at the five lessons entrepreneurs should learn before they decide to join a startup accelerator or incubator program.

Lesson 1: The founders must be committed to the success of their venture.
Joining an accelerator or incubator comes with some strings attached — startups give up between 6 to 10 percent of their equity in exchange for some cash and structured program that usually lasts around three months. Obviously, this kind of commitment should not be taken lightly.

Too often, startups join accelerator programs before they are ready or mature enough as a team. Sometimes, a company’s idea isn’t fully baked, so they end up spending as much time “creating” their business as they do “accelerating” it. As a result, that company isn’t able to leverage an accelerator’s resources efficiently throughout the entire program … The founders need to establish a vision for the business, begin laying the groundwork for the company’s products and services, and be 100% committed to the accelerator program before joining. If you can’t say with confidence that your startup meets all three of those requirements, don’t do it. Take care of those three points and proceed to the next lesson.

Lesson 2: Be prepared to leverage what you are given.
Many startups join accelerator and incubator programs with unrealistic expectations. Participation in these programs — even the most exclusive and well-known ones — by no means guarantees that you’ll raise additional money or have a successful exit. These programs provide startups with office space, free cloud services, and access to mentors, investors, recruiters and media … Those outstanding services provide participating startups with a distinct competitive advantage, but they don’t serve up success on a silver platter. If you aren’t ready work tirelessly to leverage the benefits of a startup program, don’t bother.

Lesson 3: Take advice and criticism well; mentors are trying to help.
“Mentorship” is very tough to qualify, and criticism is difficult to take … Especially if you’re 100% committed to your business and you don’t want to be told that you’ve done something wrong. Mentors in these startup programs have “been there and done that,” and they wouldn’t be in a mentorship position if they weren’t looking out for your best interest and the ultimate success of your company.

Look programs that take mentorship seriously and can provide a broad range of expertise from strategy to marketing and business development to software architecture to building and scaling IT infrastructure. Then be intentional about listening to the people around you.

Lesson 4: Do your research and make an informed decision.
With the proliferation of startups globally, we’re also seeing an evolution in the accelerator ecosystem. There are a number accelerators being positioned to help support founders with ideas on a global, regional and local basis, but it’s important to evaluate a program’s vision with its execution of that vision. Not all startup programs are created equal, and some might not offer the right set of resources and opportunities for your team. When you’re giving up equity in your company, you should have complete confidence that the accelerator or incubator you join will deliver on its side of the deal.

Lesson 5: Leverage the network and community you will meet.
When you’ve done your homework, applied and been accepted to the perfect startup program, meet everyone you can and learn from them. One of the most tangible benefits of joining an accelerator is the way you can fast track a business idea while boosting network contacts. Much in the way someone chooses a prestigious college or joins a fraternity, some of the most valuable resources you’ll come across in these programs are the people you meet. In this way, accelerators and incubators are becoming a proxy for undergrad and graduate school … The appeal for promising entrepreneurs is simple: Why wait to make a dent in the universe? Today, more people are going to college and fewer are landing well-paying jobs after graduation, so some of the world’s best and brightest are turning to these communities and foregoing the more structured “higher education” process.

Even if your startup is plugging along smoothly, a startup accelerator or incubator program might be worth a look. Venture capitalists often trust programs like TechStars and 500 Startups to filter or vet early stage companies. If your business has the stamp of approval from one of these organizations, it’s decidedly less risky than a business idea pitched by a random entrepreneur.

If you understand each of these lessons and you take advantage of the resources and opportunities provided by startup accelerators and incubators, the sky is the limit for your business. Now get to work.

Class dismissed.

Social Media for Brands: Monitor Twitter Search via Email

Posted by in Development, Social Media, SoftLayer, Tips and Tricks

If you’re responsible for monitoring Twitter for conversations about your brand, you’re faced with a challenge: You need to know what people are saying about your brand at all times AND you don’t want to live your entire life in front of Twitter Search.

Over the years, a number of social media applications have been released specifically for brand managers and social media teams, but most of those applications (especially the free/inexpensive ones) differentiate themselves only by the quality of their analytics and how real-time their data is reported. If that’s what you need, you have plenty of fantastic options. Those differentiators don’t really help you if you want to take a more passive role in monitoring Twitter search … You still have to log into the application to see your fancy dashboards with all of the information. Why can’t the data come to you?

About three weeks ago, Hazzy stopped by my desk and asked if I’d help build a tool that uses the Twitter Search API to collect brand keywords mentions and send an email alert with those mentions in digest form every 30 minutes. The social media team had been using Twilert for these types of alerts since February 2012, but over the last few months, messages have been delayed due to issues connecting to Twitter search … It seems that the service is so popular that it hits Twitter’s limits on API calls. An email digest scheduled to be sent every thirty minutes ends up going out ten hours late, and ten hours is an eternity in social media time. We needed something a little more timely and reliable, so I got to work on a simple “Twitter Monitor” script to find all mentions of our keyword(s) on Twitter, email those results in a simple digest format, and repeat the process every 30 minutes when new mentions are found.

With Bear’s Python-Twitter library on GitHub, connecting to the Twitter API is a breeze. Why did we use Bear’s library in particular? Just look at his profile picture. Yeah … ’nuff said. So with that Python wrapper to the Twitter API in place, I just had to figure out how to use the tools Twitter provided to get the job done. For the most part, the process was very clear, and Twitter actually made querying the search service much easier than we expected. The Search API finds all mentions of whatever string of characters you designate, so instead of creating an elaborate Boolean search for “SoftLayer OR #SoftLayer OR @SoftLayer …” or any number of combinations of arbitrary strings, we could simply search for “SoftLayer” and have all of those results included. If you want to see only @ replies or hashtags, you can limit your search to those alone, but because “SoftLayer” isn’t a word that gets thrown around much without referencing us, we wanted to see every instance. This is the code we ended up working with for the search functionality:

def status_by_search(search):
    statuses = api.GetSearch(term=search)
    results = filter(lambda x: x.id > get_log_value(), statuses)
    returns = []
    if len(results) > 0:
        for result in results:
            returns.append(format_status(result))
 
        new_tweets(results)
        return returns, len(returns)
    else:
        exit()

If you walk through the script, you’ll notice that we want to return only unseen Tweets to our email recipients. Shortly after got the Twitter Monitor up and running, we noticed how easy it would be to get spammed with the same messages every time the script ran, so we had to filter our results accordingly. Twitter’s API allows you to request tweets with a Tweet ID greater than one that you specify, however when I tried designating that “oldest” Tweet ID, we had mixed results … Whether due to my ignorance or a fault in the implementation, we were getting fewer results than we should. Tweet IDs are unique and numerically sequential, so they can be relied upon as much as datetime (and far easier to boot), so I decided to use the highest Tweet ID from each batch of processed messages to filter the next set of results. The script stores that Tweet ID and uses a little bit of logic to determine which Tweets are newer than the last Tweet reported.

def new_tweets(results):
    if get_log_value() < max(result.id for result in results):
        set_log_value(max(result.id for result in results))
        return True
 
 
def get_log_value():
    with open('tweet.id', 'r') as f:
        return int(f.read())
 
 
def set_log_value(messageId):
    with open('tweet.id', 'w+') as f:
        f.write(str(messageId))

Once we culled out our new Tweets, we needed our script to email those results to our social media team. Luckily, we didn’t have to reinvent the wheel here, and we added a few lines that enabled us to send an HTML-formatted email over any SMTP server. One of the downsides of the script is that login credentials for your SMTP server are stored in plaintext, so if you can come up with another alternative that adds a layer of security to those credentials (or lets you send with different kinds of credentials) we’d love for you to share it.

From that point, we could run the script manually from the server (or a laptop for that matter), and an email digest would be sent with new Tweets. Because we wanted to automate that process, I added a cron job that would run the script at the desired interval. As a bonus, if the script doesn’t find any new Tweets since the last time it was run, it doesn’t send an email, so you won’t get spammed by “0 Results” messages overnight.

The script has been in action for a couple of weeks now, and it has gotten our social media team’s seal of approval. We’ve added a few features here and there (like adding the number of Tweets in an email to the email’s subject line), and I’ve enlisted the help of Kevin Landreth to clean up the code a little. Now, we’re ready to share the SoftLayer Twitter Monitor script with the world via GitHub!

SoftLayer Twitter Monitor on GitHub

The script should work well right out of the box in any Python environment with the required libraries after a few simple configuration changes:

  • Get your Twitter Customer Secret, Access Token and Access Secret from https://dev.twitter.com/
  • Copy/paste that information where noted in the script.
  • Update your search term(s).
  • Enter your mailserver address and port.
  • Enter your email account credentials if you aren’t working with an open relay.
  • Set the self.from_ and self.to values to your preference.
  • Ensure all of the Python requirements are met.
  • Configure a cron job to run the script your desired interval. For example, if you want to send emails every 10 minutes: */10 * * * * <path to python> <path to script> 2>&1 /dev/null

As soon as you add your information, you should be in business. You’ll have an in-house Twitter Monitor that delivers a simple email digest of your new Twitter mentions at whatever interval you specify!

Like any good open source project, we want the community’s feedback on how it can be improved or other features we could incorporate. This script uses the Search API, but we’re also starting to play around with the Stream API and SoftLayer Message Queue to make some even cooler tools to automate brand monitoring on Twitter.

If you end up using the script and liking it, send SoftLayer a shout-out via Twitter and share it with your friends!

Learntrail: Tech Partner Spotlight

Posted by in Business, Partner Marketplace

We invite each of our featured SoftLayer Tech Marketplace Partners to contribute a guest post to the SoftLayer Blog, and this week, we’re happy to welcome Daniel Hamilton, CTO of Learntrail. Learntrail is a learning management system for creating, assigning, and tracking e-learning programs. It helps you train your employees and develop a more effective workforce.

The Power of Great People

In 1995, Peter Drucker, one of the founding fathers of modern-day management, shared a profoundly simple idea: “People are our greatest asset.” Today, almost two decades later, that quote is reiterated in one form or another by the top executives at the largest companies in the world. You can have the best product, a stellar marketing plan and the perfect vision, but without a great team of people to execute with those tools, your company isn’t going anywhere.

In an online world now driven by innovation, it’s easy to want to substitute “technology” for “people” as a business’s greatest asset, but I’d argue that Peter Drucker’s quote is as true now as it was in 1995. Think about it in terms of keeping your webiste online. Your server’s hardware — a powerful CPU, ample storage space, tons of RAM and a fast network connection — might dictate how your website runs when everything is going smoothly, but when your traffic spikes over the holidays or an article on your blog goes viral, your ability to respond quickly to keep your website operational will be dictated by the quality of your server admins and support staff.

While good companies focus on improving their products, great companies focus on improving their people. In 2010, Google approached the challenge of improving its people by creating GoogleEDU — a program designed to formalize the process of educating employees in new skills, strategies and perspectives. Beyond building a stronger team of smarter individuals, Google is clearly investing in its employees, and that investment goes a long way to engender loyalty and job satisfaction.

What if your business doesn’t happen to have Google’s resources or a $269 billion market cap? That’s the problem Learntrail set out to solve. Our platform was designed to make it easy for businesses to create stunning, full-featured multimedia courses that can be monitored and tracked in detail with a few clicks.

Learntrail Chalkboard

You can bring your new-hire orientation program online, centralize training documents for new products, or create simple lessons about company-specific procedures through a sleek, easy-to-use portal. You’ll also get real-time reports about your team’s progress, so you’ll know exactly how your training is being used by your employees. To prove how confident we are that Learntrail will meet your needs, we have a risk-free, no credit card required 14-day trial that lets you kick the tires and get a feel for how Learntrail can work for your business.

Your people are your greatest asset.

iptables Tips and Tricks: CSF Configuration

Posted by in Development, Tips and Tricks

In our last “iptables Tips and Tricks” installment, we talked about Advanced Policy Firewall (APF) configuration, so it should come as no surprise that in this installment, we’re turning our attention to ConfigServer Security & Firewall (CSF). Before we get started, you should probably run through the list of warnings I include at the top of the APF blog post and make sure you have your Band-Aid ready in case you need it.

To get the ball rolling, we need to download CSF and install it on our server. In this post, we’re working with a CentOS 6.0 32-bit server, so our (root) terminal commands would look like this to download and install CSF:

$ wget http://www.configserver.com/free/csf.tgz #Download CSF using wget.
$ tar zxvf csf.tgz #Unpack it.
$ yum install perl-libwww-perl #Make sure perl modules are installed ...
$ yum install perl-Time-HiRes  #Otherwise it will generate an error.
$ cd csf
$ ./install.sh #Install CSF.
 
#MAKE SURE YOU HAVE YOUR BAND-AID READY
 
$ /etc/init.d/csf start #Start CSF. (Note: You can also use '$ service csf start')

Once you start CSF, you can see a list of the default rules that load at startup. CSF defaults to a DROP policy:

$ iptables -nL | grep policy
Chain INPUT (policy DROP)
Chain FORWARD (policy DROP)
Chain OUTPUT (policy DROP)

Don’t ever run “iptables -F” unless you want to lock yourself out. In fact, you might want to add “This server is running CSF – do not run ‘iptables -F’” to your /etc/motd, just as a reminder/warning to others.

CSF loads on startup by default. This means that if you get locked out, a simple reboot probably won’t fix the problem. Runlevels 2, 3, 4, and 5 are all on:

$ chkconfig --list | grep csf
csf             0:off   1:off   2:on    3:on    4:on    5:on    6:off

Some features of CSF will not work unless you have certain iptables modules installed. I believe they are installed by default in CentOS, but if you custom-built your iptables, they might not all be installed. Run this script to see if all modules are installed:

$ /etc/csf/csftest.pl
Testing ip_tables/iptable_filter...OK
Testing ipt_LOG...OK
Testing ipt_multiport/xt_multiport...OK
Testing ipt_REJECT...OK
Testing ipt_state/xt_state...OK
Testing ipt_limit/xt_limit...OK
Testing ipt_recent...OK
Testing xt_connlimit...OK
Testing ipt_owner/xt_owner...OK
Testing iptable_nat/ipt_REDIRECT...OK
Testing iptable_nat/ipt_DNAT...OK
 
RESULT: csf should function on this server

As I mentioned, this is the default iptables installation on a minimal CentOS 6.0 image, so chances are good that these modules are already installed on your system. It never hurts to check, though.

The CSF Configuration File

The primary CSF configuration is stored in the well-documented /etc/csf/csf.conf file. CSF is extremely configurable, so there are a lot of options to read over. Let’s take a look over some of the more important features:

India: Using Global Technology to Go Hyper-Local

Posted by in Executive Blog, International

Bill Gates once told a journalist that everyone should care about developments in India because the world’s largest democracy (of 1.2 billion people) and tenth-largest economy is quickly catching up with us. I recently had the opportunity to see those developments first-hand, and I wholeheartedly agree with Bill’s sentiment. Innovation and technology breakthroughs are not owned by or limited to the United States, and as international markets mature, we’re going to see more and more entrepreneurship and startup activity overseas. Now I don’t mean to imply that the demise of Silicon Valley is imminent, but its influence will be greatly diminished in the future, and that’s not necessarily a bad thing.

I just returned from a round-the-world trip that included nearly two weeks in India as part of a 500 Startups-sponsored market exploration tour called Geeks on a Plane. The tour stopped through Bangalore, Mumbai and New Delhi, with meetups for local entrepreneurs, startups, investors and some of the most influential companies in India’s technology ecosystem. While in India, I had the chance to meet several SoftLayer customers — including Zoomin, PowerWeave, and Vidya Mantra — and their insight into the growing technology culture in the region was eye-opening.

India

One of the most interesting characteristics shared by many of the entrepreneurs I spoke with was that they were building businesses with a “hyper-local” focus: Unique business models that are specifically geared toward serving local communities while leveraging the latest technologies in mobility and e-commerce. This distinction is particularly noteworthy because they didn’t assume that they’d need to succeed in the US market or compete with companies in the US to build their businesses … And they’re absolutely right. The opportunities that exist for hyper-local entrepreneurs in these emerging markets are staggering.

FlipKart is known as “The Amazon of India.” It’s very similar to the online shopping giant most of us know and use regularly, but with some unique regional twists. For example, because credit card and electronic payments in India are not as prevalent or reliable as they are in much of the world, orders are taken via both an online ordering system and through FlipKart call centers. Once processed, a highly developed network of “scooters” delivers about 50 percent of FlipKart’s orders, and the payment is provided at the customer’s door — IN CASH. While that might seem simplistic, each courier has a smartphone that allows them to become a geo-located, connected, data sharing entity. Hundreds of millions of dollars in FlipKart orders are delivered each year with very few issues, despite the fact that most of us can’t even imagine how the company could operate that way in the US.

Another great example of how innovators are using technology to redefine businesses is redBus, India’s largest bus ticketing company. A huge percentage of travel in India is done very inexpensively by bus, and before redBus came on the scene, travelers took their chances by buying tickets through middlemen and ticket brokers, often getting ripped off or becoming victims of double-booking. By centralizing the ticketing process, redBus is able to provide a reliable way to book a seat on any of India’s vast system of buses via phone, online or in person. redBus offers the largest selection of bus seats in the country with over 350 bus operators and a flexible network of boarding points, timing and bus types. It’s an incredibly simple service that meets a clear need for a hyper-local audience by leveraging the technologies being built and improved around the world.

If my two weeks in India taught me one thing, it was that the startups don’t need to conquer international markets … They can strive to service their local communities and interests, and they’ll be just as successful (if not more). Our Catalyst program has just begun its international expansion into India, and the future certainly looks bright. In fact, I’m proud to announce that we’ve already signed up our first Catalyst program member in India with many more to come!

As we continue working with startup communities around the globe, I learn more and more about how the world is changing, and I get a stronger appreciation for the cultural and economic ties that bind us all together.

Stay tuned!

Script Clip: HTML5 Audio Player with jQuery Controls

Posted by in Development, Tips and Tricks

HTML5 and jQuery provide mind-blowing functionality. Projects that would have taken hours of development and hundreds of lines of code a few years ago can now be completed in about the time it’ll take you to read this paragraph. If you wanted to add your own audio player on a web page in the past, what would it have involved? Complicated elements? Flash (*shudders*)? It was so complicated that most developers just linked to the audio file, and the user just downloaded the file to play it locally. With HTML5, an embedded, cross-browser audio player can be added to a page with five lines of code, and if you want to get really fancy, you can easily use jQuery to add some custom controls.

If you’ve read any of my previous blogs, you know that I love when I find little code snippets that make life as a web developer easier. My go-to tools in that pursuit are HTML5 and jQuery, so when I came across this audio player, I knew I had to share. There are some great jQuery plugins to play music files on a web page, but they can be major overkill for a simple application if you have to include comprehensive controls and themes. Sometimes you just want something simple without all of that overhead:

Oooh… Ahhh…

That song — Pop Bounce by SoftLayer’s very own Chris Interrante — is written in five simple lines of HTML5 code:

<audio style="width:550px; margin: 0 auto; display:block;" controls>
  <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.ogg" type="audio/ogg">
  <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>

If IE 9+, Chrome 6+, Firefox 3.6+, Safari 5+ and Opera 10+ would all agree on supported file formats for the <audio> tag, the code snippet would be even smaller. I completely geek out over it every time I look at it and remember the days of yore. As you can see, the HTML5 application has some simple default controls: Play, Pause, Scan to Time, etc. As a developers, I couldn’t help but look for a to spice it up a little … What if we want to fire an event when the user plays, pauses, stops or takes any other action with the audio file? jQuery!

Make sure your jQuery include is in the <head> of your page:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>

Now let’s use jQuery to script separate “Play” and “Pause” links … And let’s have those links fire off an alert when they are pressed:

$(document).ready(function(){
  $("#play-button").click(function(){
   $("#audioplayer")[0].play();
   alert('You have played the audio file!');
  })    
 
  $("#pause-button").click(function(){
   $("#audioplayer")[0].pause();
   alert('You have paused the audio file!');
  })    
})

With that script in the <head> as well, the HTML on our page will look like this:

<div class=:"audioplayer">
  <audio id="audioplayer" name="audioplayer" controls loop>
    <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.ogg" type="audio/ogg">
    <source src="http://cdn.softlayer.com/innerlayer/Interrante-PopBounce.mp3" type="audio/mpeg">
  Your browser does not support the audio element.
  </audio>
 
  <a id="play-button" href="#">Play!</a>
  <a id="pause-button" href="#">Pause!</a>
</div>

Want proof that it works that simply? Boom.

You can theme it any way you like; you can add icons instead of the text … The world is your oyster. The bonus is that you’re using one of the lightest media players on the Internet! If you decide to get brave (or just more awesome), you can explore additional features. You’re using jQuery, so your possibilities are nearly limitless. If you want to implement a “Stop” feature (which returns the audio back to the beginning when “Stop” is pressed), you can get creative:

$("#stop-button").click(function(){
    $("#audioplayer")[0].currentTime = 0; // return the audio file back to the beginning
}

If you want to include some volume controls, those can be added in a snap as well:

$("#volumeUp").click(function(){
    $("#audioplayer")[0].volume +=0.1;
}
 
$("#volumeDown").click(function(){
    $("#audioplayer")[0].volume -=0.1;
}

Try it out and let me know what you think. Your homework is to come up with some unique audio player functionality and share it here!

Startup Series: Kickback Tickets

Posted by in Business, Startup Series

The very first client I recruited to Catalyst when I joined the CommDev team about a year ago happens to be one of Catalyst’s most interesting customer success stories … and I’m not just saying that because it was the first partner I signed on. Kickback Tickets — an online ticketing platform that utilized crowdfunding — has simplified the process of creating and funding amazing events, and as a result, they’ve made life a lot easier for the startup, developer and networking organizations that fuel Catalsyt.

Anyone who’s organized events knows that it often involves a financial risk because it’s hard to know whether the event will be well-enough attended to cover the costs of putting on the event. With Kickback Tickets, an event is listed an funded ahead of time, and when it reaches its “Tipping Point” goal of tickets ordered, it’s completely funded, the early supporters are charged, and the ticket sales continue.

The process is simple:

Kickback Tickets

Event updates, guest registrations and QR-coded tickets are provided to attendees to make check-in seamless, so the hosts of each event don’t have hassle with those details. Kickback’s revenue comes from a small fee on each ticket for each successfully funded event, and they’ve got a ton of momentum. After signing on with Catalyst in March 2012, Kickback went live with an open beta in November 2012, and they launched their out-of-beta site in February 2013. They’ve successfully funded more than 20 events, and new events are added daily.

Kickback Tickets

When I met the Kickback founders Jonathan Perkins and Julian Balderas, I was attending SF Beta (my first official event as a SLayer). At the time, Jonathan and Julian were a couple of bankers with an innovative idea to help organizations alleviate the financial risk of planning and putting on events by enlisting community support. I told them about my experience as the COO of a small non-profit startup up called Slavery Footprint (also a Catalyst partner), and I guess they could relate to the challenges SoftLayer helped us overcome because they were excited to join.

In their own words, Jonathan and Julian explain that their partnership with Softlayer and the Catalyst program has been extremely valuable:

SoftLayer provides a rock-solid technical foundation and allows us to focus more resources on business development. On the technical side, what Softlayer offers is impressive — super fast speeds and an intricate level of control over the hardware. On the personal side, the mentorship and networking benefits of the program have been very helpful. We’ve always found the Catalyst team to be available to chat about any questions we had, ranging from development to biz dev to fundraising.

As they continue to expand their platform, it’s going to be exciting to watch Kickback become a true force in the events space. Organize your next event with Kickback and make sure it’s a success.

Oh, and if you want to speak to Jonathan and Julian, just reach out to me and I’ll happily make the introduction.
