Divertido’s Network @ The Aquatic Lounge

By Mack D. Male · March 31, 2010 at 10:33pm

Tonight I finally made it out to a Divertido event! Hosted at the Eye Care Group on 104th Street and Jasper Avenue, Network @ The Aquatic Lounge was Divertido’s twelfth event since they launched in September 2008. I’ve wanted to attend one of their events for a long time now, but always had something else going on. Here’s the Divertido elevator pitch:

Divertido Urban Jaunt is redefining what networking is all about by creating extraordinary events that go beyond the typical business mixer. The possibilities are endless! Come out, experience, enjoy and expand your network the Divertido way!

What is the Divertido way? First, each event has a theme, and features related decor, lights, and other surprises. Tonight, for the aquatic theme, there were blue lights and balloons, sushi, small fish bowls, and yes, a mermaid! Second, events are held at unique venues, unlike your typical networking event. Tonight’s was at the Eye Care Group, and previous events have been held at venues like the Coney Island Candy Shop, Spinelli’s, Ginger Clothing & Apparel, and EnPrivado. Third, the vibe is informal and hip. There’s a DJ, beer and wine, and business professional dress (though there is no official dress code).

There’s no agenda, no speeches, and interestingly, no common thread among the attendees (other than the fact that they heard about Divertido). There was a really diverse group of people there tonight – I met a realtor, financial manager, a “chief uptime officer” (love it), and many others. It’s great if you love to meet new people!

Divertido was created by Roberto Moreno and Elisse Heine. You can see an interview with them here. You can see the rest of my photos from tonight here. Check out the website for more information and future events.

Please don’t send me large files via email

By Mack D. Male · August 27, 2008 at 8:20pm

email If you’ve ever sent me a large file through email, you probably know how much I hate it. No one escapes a lecture! Just because GMail and other services give you gigabytes of storage, doesn’t mean that it’s okay to send really large attachments. I was happy to read that one my favorite blogs posted about the subject today. From the Microsoft Office Outlook Team Blog:

Putting any issues with your e-mail service provider’s limits on large messages aside, sending large attachments through e-mail is still a bad idea for a number of reasons.

In the post, Outlook Program Manager Ryan Gregg outlines a few of the reasons why you shouldn’t send large files via email – mail servers may reject large files, mailboxes may go over their quota, attachment bloat, attachments may be out of date, etc. He also outlines a number of alternatives, including SharePoint or a Shared File Server, Office Live, photo sharing sites like Flickr, and video sharing sites like YouTube.

When you use one of these alternative ways to share files with your friends, family, or colleagues you help them keep your mailbox and theirs clean, and you can be sure that your file will be available no matter what service or program your e-mail recipients are using.

I would add a couple more reasons to avoid sending large files: slow Internet connections and small devices. If I’m checking email on an unreliable connection, the last thing I want to do is wait for your images to download. If I’m checking email on my iPod touch or a cell phone, I might not be able to read the files anyway.

If you’re sending photos, why not stick them on Flickr and email a link? Same goes for video – use a site like YouTube. Some other alternatives include Box.net, Amazon S3, and SlideShare.

It doesn’t take a lot of extra effort to stick your file online somewhere first, so why not just do it? Send links to large files via email, not the files themselves!

Don’t worry about undersea cable cuts

By Mack D. Male · March 13, 2008 at 10:46pm

inet Remember all the undersea cables that were cut last month? I still haven’t come across a definitive reason for the disruptions, though a February 19th article at The Inquirer claims it was sabotage. I’m not sure about that, but the one thing that is clear is that everyone has moved on. For instance, Google announced a few weeks ago that it was joining a consortium building a new $300 million undersea fiber optic cable linking the US and Japan:

The new cable system – named Unity – will address broadband demand by providing much needed capacity to sustain the unprecedented growth in data and Internet traffic between Asia and the United States. Unity is expected to initially increase Trans-Pacific lit cable capacity by about 20 percent, with the potential to add up to 7.68 Terabits per second (Tbps) of bandwidth across the Pacific.

Om Malik has a good roundup of reasons for why Google got involved.

Just a few days ago, AT&T announced big investments in data centers here in Canada as well as undersea cables in Asia and Australia:

“Recent cable cuts in Europe and Asia show we need to further improve resiliency and re-routing capability,” he says.
AT&T has the largest private fleet of cable-laying ships in the world, and operates its global network on 71 undersea cables laid over 450,000 miles…

If you do a quick search you’ll find a bunch of other announcements for cable systems, such as this new one in Africa, and this upgraded one that links Singapore and France.

Maybe new cables are being laid faster than they are being cut after all

Also – check out this post at the Royal Pingdom blog:

Over 260 ISPs, including major network providers like AT&T, Sprint and Verizon, all cross-connect in a single data center in an office building in downtown LA.

This has been going on for 20 years. So much for not having a single point of failure.

A few cut cables seems kind of irrelevant compared to that.

Fifth undersea cable cut

By Mack D. Male · February 6, 2008 at 4:00pm

inet cable With each passing day, another undersea cable serving the Middle East is severed. At least that’s the way things are going right now! Slashdot reported earlier today on the fifth incident, originally suggesting that it resulted in all of Iran going offline. They later backtracked as it became clear that Iran was still on the grid.

Not surprisingly, there is a Wikipedia entry up with information on the 2008 submarine cable disruption. It includes a timeline with details about which cables were damaged. In case you’re wondering, there’s a list of international submarine communications cables at Wikipedia too.

The cable known as SEA-ME-WE 4 has been affected the most, which is significant as it provides the primary connection between Europe, the Middle East, and South East Asia. Combined with the FLAG cable cut, the BBC has pointed out that only the older SEA-ME-WE 3 is currently connecting Europe and the Middle East, with capacity reduced by about 75%. This cable has experienced a couple disruptions of its own in the past. The first was in July of 2005, which mainly affected Pakistan. The second was back in December of 2006, the result of an earthquake known as Hengchun which occurred off the coast of Taiwan. Perhaps there are more that I haven’t found yet. Heck, portions of the cable have even been stolen and sold!

In my post yesterday, I expressed hope that the recent incidents would result in some action to prevent the situation from getting worse. The more I read about undersea cables however, the clearer it becomes that these events are certainly nothing new. It seems as though cable disruptions aren’t as uncommon as one might think.

Certainly the fact that five cables have been cut in less than two weeks should raise some eyebrows, however.

Here are some additional resources:

Undersea cables carry 95% of the world’s telephone and Internet traffic

By Mack D. Male · February 5, 2008 at 7:16pm

internet cable On Friday I posted about the three undersea cables that were cut, disrupting Internet access in South Asia and the Middle East. Since then, another cable has been cut, and the story is finally starting to get some coverage. The BBC posted about the issue today, and included a really interesting diagram that explains the parts of an undersea cable.

The most interesting article however, comes from the International Herald Tribune:

Most telecommunications experts and cable operators say that sabotage seems unlikely, but no one knows what damaged the cables or whether the incidents were related.

According to the Egyptian government, no ships were in the vicinity of the cables when they were cut. Seems suspicious to me that four cables have been severed in such a short period of time, but who knows. It seems that this bit of Internet infrastructure isn’t as sturdy as one might think.

“This has been an eye-opener for us, and everyone in the telecom industry worldwide,” said Colonel R.S. Parihar, the secretary of the Internet Service Providers Association of India.

Let’s hope the recent incidents result in some action, before the situation gets any worse. Traffic has been re-routed over the last week, but how well would that work if many more cables were cut, say during an attack?

Maybe you’re not convinced that ensuring the safety of undersea cables is important. Consider this:

Undersea cables carry about 95 percent of the world’s telephone and Internet traffic, according to the International Cable Protection Committee, an 86-member group that works with fishing, mining and drilling companies to curb damage to submarine cables.

Talk about putting all your eggs in one basket!

If I were a terrorist…

By Mack D. Male · February 1, 2008 at 5:22pm

…I’d launch an attack on undersea cables around the world.

On Wednesday, two such cables near Egypt were cut resulting in a major disruption of Internet access in south Asia and the Middle East. Today, another cable was cut near Dubai. In both cases the cause remains unknown, but ship anchors seem likely.

Why bother with bombing train stations when you can disrupt global communications, apparently by dropping a few anchors? Maybe it’s sick that I thought about terrorism when reading the news, but seriously, it seems to me that this could be a real threat. And I haven’t heard anything about preparing for it.

The image above gives you a good overview, but this very detailed, up-to-date map of the globe’s undersea cabling is better (and much bigger).

Wi-Fi Heartbeat

By Mack D. Male · March 16, 2007 at 11:34pm

Oh man I totally need to get me one of these! BoingBoing posted yesterday about a DIY project that can give you a “sixth sense for wireless networks.” Here’s the project description:

This project is for a small electronic unit that allows the user to sense the presence and relative signal strength of wireless hotspots. It can be worn as a pendant or carried in a pocket. It is “always on” and communicates the presence and signal strength of an in-range hotspot by way of sequences of pulses – like a heartbeat you can feel. The stronger and faster the “heartbeat”, the stronger the wireless signal detected.

Just imagine walking around a city’s downtown with this thing on…it would never stop pulsing! Very cool idea though.

Telus finally upgrading broadband network

By Mack D. Male · September 8, 2006 at 8:38pm

Dickson sent me this story today about Telus. I recently got rid of my Telus landline and while I am not a big fan of the company, I have been pretty happy with their mobile phone service, and until a couple years ago when I lost my static IP, I was happy with their ADSL service too. That said, the Internet offerings have always been truly “North American”, and by that I mean slow and expensive relative to the rest of the world. Finally though, Telus is going to make some changes:

Telus Corp. says it is investing nearly $800 million over the next three years to beef up its broadband network so it can offer its customers a wide range of new services, including high-definition television.

The company said its proposed infrastructure will allow it to double internet access, to speeds of 15 or 30 megabits a second.

That’s still a far cry from the 100 megabits/second you can get to your house in Hong Kong, for example, but it is markedly better than what we have now. Apparently the entire project will be completed by 2009 (at which time, the rest of the world will probably be faster still).

OpenDNS

By Mack D. Male · July 10, 2006 at 11:37pm

I came across OpenDNS today via Geek News Central. I have been meaning to look for something like this for quite some time. Basically, it is a DNS service, used by your computer to look up the IP address of a domain name. Whenever you setup your Internet connection on your computer, or router, or other device, you have to enter DNS servers that it can use to “resolve” domain names (convert to an IP). Until finding OpenDNS, I had just used the ones I was given from Telus six years ago, because I had memorized them. I always knew there was something better though:

OpenDNS makes the Internet experience safer, faster and smarter for you and everyone using your network. OpenDNS service is free. OpenDNS makes money by serving clearly labeled advertisements on search results pages where we cannot resolve your intent (i.e., not a known typo).

They have a big cache, and geographically dispersed servers, which should speed up requests. OpenDNS will also identify phishing sites and display a warning message. And finally, they will automatically correct spelling mistakes (I want this feature, though it doesn’t seem to be working for me yet, maybe I have to restart – I already flushed the DNS and restarted the browser…).

I just started using it this evening, so I don’t have much to report yet. I don’t think they’ll make any money off me directly, as I won’t click the ads on their search page, but they might indirectly, as I’ll probably start using their servers when I setup computers and networks for people. Give it a shot if you want.

Net Neutrality

By Mack D. Male · April 4, 2006 at 9:16pm

I haven’t said much about so-called “network neutrality” yet, but I do think it is a very important issue. I don’t pretend to know all about it, but I have read enough to form some opinions. First off, here’s how the term is defined at Wikipedia:

Network neutrality is a proposed principle of network regulation. It asserts that, in order to promote innovation, network service providers such as telephone and cable internet companies should not be permitted to dictate how those networks are used (ie. not permitted to ban certain types of programs, or to ban certain types of devices connecting to the network).

Currently, this is a big political issue in the United States, but I am not sure if it has received much attention elsewhere. A draft bill scheduled to be voted on tomorrow will be revised to ensure that the FCC has tools at its disposal to address violations. This is the main idea behind the bill, at least as I understand it:

The draft bill says broadband providers must provide connectivity speeds “at least equal to the speed and quality of service” that the operator offers for its own content or that of its affiliates, and “make available the same bandwidth” to everyone.

I encourage you to read the article linked to above (at CNET News.com) as it contains some background information in addition to the current happenings.

I was a little torn between whether or not network neutrality is a good idea or not. My gut feeling and initial reactions were that net neutrality is vital for the future of the Internet, and it must be protected. As I thought about it a little more, I turned to economics, and thus my secondary thoughts were that the market should decide how these services are charged for and offered. Upon still further consideration, I feel that net neutrality is important and we should all ensure the Internet remains neutral.

There are too many “ifs” associated with a network that might become tiered or fragmented in some way – who knows what the providers might do. The last thing I would want as a business consumer is to have different Internet access, whether in performance or throughput or bandwidth, than a larger company simply because the Internet providers can squeeze large sums of money out of them.

One of the great things about the Internet is that it is open and available to everyone (I realize there are people who cannot yet afford access, or areas for which access is unavailable, but as a blanket statement, the Internet is pretty open). I think it’s important we keep it that way, so I hope laws concerning network neutrality are ratified in the United States, and eventually, elsewhere.
