Understanding Upload and Download Speeds

Posted by Nolan at 11:46 AM on July 14, 2009

work_signA divine revelation came to me in a construction induced traffic jam on the interstate.  Three were lanes reduced to one and slowed to a safe speed as we passed construction workers.  New cars entering the road compounded the issue as we plodded along.  It was then I realized this was the example I needed to explain the speed of the internet to many people.

The problem?  Friends sign up for high speed internet say for example 6mb down and 1mb up.  Nothing spectacular but good for the normal user.  They become frustrated when experiencing slow downloads from say youtube, flickr, or a software updater.  “I have high speed internet and they don’t give it to me!  Youtube is always buffering and files download slowly.”  The interstate traffic jam should help explain it.

The travel on the interstate is only as fast as the slowest part of the road.  In the case of youtube, your internet is 6mb down, but youtube servers may not be able to stream the video faster than 150kb, much slower.  Facebook is notorious for being overwhelmed at the number of page requests.  As a result of so many requests it becomes like all of the cars trying to squeeze into one lane.

A personal example would be the upload speed to my blog.  It does not matter what my local internet speed is, I can only upload as fast as my host server will allow me.  For instance my wife and I went to the fair the other day.  Hopped on the highway and buzzed the 5 miles in no time (equal to our bandwidth speed).  We parked the car with no problem (opened up a connection port to a server).  And then we waited in a long line to enter through a narrow gate with only two ticket agents (the server speed).  It didn’t matter how fast we travelled to get there or how easy parking was.  The ticket agents could only go so fast.

So calm down everyone in this highspeed life of ours.  Yes everything is getting quicker, but there are still narrow places in the road.  Some servers are overloaded, some computers are slow, sometimes things break.  You can be assured that the average speed will continue to increase.

Point That Finger of Blame Carefully

Posted by susabelle at 7:39 AM on July 14, 2009

bullseyeLast week, news of a run of Denial of Service (DOS) attacks on South Korean and United States’ government websites was announced.  Almost immediately, blame for the attacks was being placed on North Korea and North Korean servers, probably due to some of the escalating tensions between the U.S./South Korea, and North Korea.  It is really easy to make such connections, and often speculation disguises itself as fact when these news reports were circulated.

But today it was announced that the attacks actually originated in the U.K. and involved ‘bot computers in 68 countries all reporting back to the main computer in the U.K.  This information was released today by Hanoi-based Bkis  at the request of APCERT, the Korean Computer Emergency Response Team.  APCERT is part of a larger organization of watchdog teams in Southeast Asia/Pacific that tracks and analyzes data streams and attacks that originate, or are focused on, that particular region of the world.

It is easy enough to place blame with assumptions.  It happened in Oklahoma City when we blamed foreign terrorists for the Murrow Building bombing, only to find out later that it was domestic terrorism.  While it is important to spread information about events that impact national and computer security, it is just as important to spread truthful information.  And in the case of these most recent DOS attacks, there is no direct evidence at this point linking North Korea to the attacks.  And until there is, we shouldn’t be pointing fingers of blame.

Blix has turned their results over to the U.K. and U.S. governments for followup.

In The Land of iPhone, iTunes is Still King over All Others

Posted by Jeffrey Powers at 2:34 PM on July 13, 2009

This last week I gave up my older HTC 8125 for the Apple iPhone. It’s been an interesting experience so far and I really like how the phone works. I also like the apps – Especially the ones that keep me productive. I am not really a gamer or a fluff app person – I may download and try it, but those apps usually go to the wayside.

Two apps I was excited to try out were Stitcher: a Podcast aggregation site, and Pandora: for online radio stations. I’ve used both before getting the iPhone and couldn’t wait to install and try them.

Of course, I could just use the integrated iTunes program on the phone. It does music and aggregates podcasts. However, I like to try out all the options – make sure I have the easiest and best program.

So let’s take a look at each program and see what advantages there are to it.

Stitcher

Stitcher

If you haven’t tried this site out yet, you should. Stitcher is a Podcast aggregator. You can get many great podcasts, add them to your watch list and be alerted when new episodes are available. You can listen to your shows on your iPhone, Blackberry or on any PC.

In turn, iTunes also has an area to download podcasts. You can search the store and download episodes. However – As Todd noted in his last podcast – While the PC version lets you subscribe to the podcast, the iTunes store only allows you to add episodes. I have yet to find a way to “Subscribe” from the iPhone.

Pandora

Pandora

Pandora

Pandora has just been in the news because of the agreement they have reached for Internet radio. You can join up with a radio station, listen to it and move on. The control of the music is not that great; which was a design of the new agreement.  You can skip songs, but only 6 per hour. All this, so you won’t have to pay for any music you want to hear.

Flipping over to iTunes, you can pay .99 cents a song, sync up with one computer to get your playlist of songs and go. You can customize your playlists and listen to new songs. They even give you some free ones.

There are other apps, like Audio books. Audible lets you read books right from your iPhone. iTunes also has an Audiobook option. I have not tested that feature yet, so we will leave it as a footnote.

iTunes

iTunes

The Advantage

The biggest advantage iTunes has is that if you have to use another application; like checking your email, whatever you are listening to will continue to play. If you try the same for Pandora or Stitcher, the program will close. Once the application is re-opened, you will be able to continue listening. However- in the case of Pandora – it will not continue where it left off.

iTunes will also do video – TV shows and even Video Podcasts. While there is no Hulu application (yet), you do have the option of YouTube – which also comes with the native OS.

I don’t want to make it sound like you shouldn’t download Pandora or Stitcher. They are great programs in their own right. The applications are free and can be an addition to any iPhone. That is why they are on my iPhone to stay.

Is Twitter a Fad, or Here to Stay?

Posted by susabelle at 6:21 AM on July 13, 2009

twitterThis will likely be the shortest article I’ll have ever written.  Longer than 140 characters, but still, short.

The question is, is Twitter a fad, or here to stay?  I saw a reference to Twitter as a fad in a recent article in the USAToday.  The author of the article was interviewing Robert Bartholomew about the book he just co-authored, Outbreak!, The Encyclopedia of Extraordinary Social Behavior.  The Encyclopedia is a compendium of public overreactions to events or occurrences.  The author asks about Twitter and whether it is a fad, and Bartholomew’s answer:

“Most fads are not social delusions but are short-term infatuations. Only time will tell whether Twitter is a fad and will go the way of the CB radio after a year or two of intense interest or if it will become a more permanent fixture of our social landscape. Fads typically offer status but quickly fade when ‘everyone’s doing it’ and hence loses its novelty.”

That’s exactly how I feel about it.  I am not a Twitterer, yet.  And I don’t know if I will be, but I’m often slow to jump on fadish bandwagons.  I’m waiting to see if it will be something that would be valuable to me to use, or just another time-waster like Facebook and MySpace and LinkedIn  have turned out to be for me.  Remember when LinkedIn was “the next great thing?” Yeah, me too.

Why Should I Get Excited About a Google Operating System?

Posted by susabelle at 7:42 AM on July 11, 2009

I, along with every other geek this week, have invariably heard about the new operating system to be produced by Google.  I have read multiple articles and really haven’t formed an opinion one way or the other about whether it will be good or not.

My real concern is about the ability of any operating system to truly overtake Windows as a standard.  As much as we hate Windows and complain about the things that don’t work or get broken, the fact is, Windows is a known commodity, and the majority of users we will work with will be Windows-literate.  Changing how they think, and operate, a computer, is a daunting task, and not one I will undertake lightly.  [Yes, I am deliberately and knowingly leaving out the Mac discussion for this article.]

I am my family’s de facto technical adviser and repair-woman.  When I get a call from my mother in Florida, I have to try to walk her through a fix or software setting via the phone.  She has used Windows the last 8 years.  My dad, who lives about an hour away, and his wife, both use Windows machines.  I have two brothers who also live within a few hours, who use Windows machines.  Needless to say, I’ve gotten really good at talking them through minor issues over the phone.  They understand most of the processes they are being asked to do, and can muddle their way through with my instructions.

I cannot imagine teaching any of these people how to use Linux.  One of the reasons I’ve not personally embraced it is because of all the “tinkering” that must be done to make changes, get programs to work properly, have all of your features available, etc.  Linux is not intuitive, and intensely harder to manage overall because of the hands-on adjustments you have to make to it.  And that’s okay for a geek, but not so good for the everyday user who just wants to sit down and surf the ‘net, type an email, or manipulate a photo or two from their digital cameras.

So when I look at Google’s offer of an operating system, I am more or less shrugging my shoulders and thinking “big deal.”  Another thing to learn, that may or may not be any easier to navigate and support than another free operating system already available (Linux).  I don’t see wide-spread acceptance of any new operating system at this point, despite the foibles and flaws of Windows.  At this point in the game, it is a little late to be putting Windows back in the barn and getting people to convert to something completely different.

Of course, I could be wrong.  It would be nice to think I’m wrong.  But it’s got to be more than “hey look, it’s FREE” to get me to look twice.  Because for all intents and purposes, Windows is free too, because it comes already installed on most new computers.  I know it’s not technically free, but the perception is that it’s free.  So Google’s new operating system has got to be bang-up better than what we already have to even have a chance of cracking the market and becoming a Windows killer.

And I have yet to see the app come along that can completely submerse Windows or other Microsoft software from majority use.  The fact remains that most businesses and home computers are loaded with Windows and Microsoft Office and Microsoft Internet Explorer, and that the majority of people are using those products in their daily lives.

Google’s got a very tough row to hoe with this one.

Firefox 3.5 Mac Glitches

Posted by Nolan at 6:48 AM on July 9, 2009

Mozilla Firefox 3.5 Release NotesI upgraded to Firefox 3.5 about a week ago.  To be honest I have been unimpressed.  I am sure that somehow there is better protection under the hood.  Perhaps even a slight speed increase.  However, I have found more problems than obvious cures.

  1. Upon opening it freezes if having trouble loading the home page for some reason.  The standard “X” in the corner is unresponsive along with the normal top menu. Leaving no choice but to force quit the application and relaunch.  It used to crash and relaunch itself at least.
  2. Firefox will sometimes hesitate and freeze while opening a new tab.  For instance, I have three tabs running and click a link to open in a new tab.  Generally, I keep reading the prior open tab’s article while the new tab finishes loading.  On occasion my current tab freezes not allowing me to scroll down.  It stays frozen until the other tab finishes rendering.  Not all of the time, just part of the time.
  3. Most recently it started to runaway with the processor.  I had one tab open on a very basic text only page.  There was nothing trying to auto-refresh on the page.  And yet it ran away with 80% of both cores.  Yikes.  Something in there went horribly wrong.  Once again a force quit and relaunch.

So as a whole, every day I eagerly await an update to this update.  Granted I am still a fan, just a bit frustrated not unlike when portions of my favorite highway go under construction.  I’ll be patient, but please hurry.

How heavy is a useable Petabyte?

Posted by Matthew Greensmith at 6:44 AM on July 9, 2009

The team at MatrixStore have a post up calculating the weight of a petabyte of storage today compared to 1980.  Needless to say todays weight was a lot less.  The article was inspired by a post on Gizmodo illustrating how big a PB is.  There are two problems with the calculations though.

  1. 2TB is a marketing number.  The formatted capacity of 500 2TB drives is more like 916TB
  2. The weight is for the drives alone, which is not storage you could actually access and use

If we want to use 2TB drives we need a system that can hold 3.5″ drives.  The highest capacity tray I know of for these drives takes 48 SAS or SATA drives in 4U of rack space (about 7″ x 19″ x 24″).  You can sit multiple of these behind a single RAID box which would provide access for your computer over IP or FC depending on the type.

To get a real petabyte of base 2 usable storage you would need 546 2TB drives.  The whole setup including racks and power would weigh 1400kg or 3100lbs.  It would also consume 12kVA of power spitting out 39KBTU/hr of heat.

546 drives is for a PB of raw storage though.  In reality you would need to protect it from drive failures using RAID.  If we go for as littlle overhead as possible we can create 24 disk RAID 6 sets which would have about 40.4TB useable storage each.  For this we need about 600 drives which adds another 100kg to the weight.  Still about 1/180th of the weight of a PB just 30 years ago.

Is Google going to crack?

Posted by Nolan at 6:12 AM on July 9, 2009

googlechromelogoWith great interest I have been following the news articles and rumors of the upcoming Google OS release.  I am trying to wrap my mind around the Google business plan.  From search engine to online advertising dominance to Gmail to Google docs to Google Code to Google Mobile OS Android to Google Chrome to Google Wave to Google Voice to Google Chrome OS.  Not to mention a few other less known projects and discontinued items.  It is apparent that Google wants to control/manipulate our online life. And of course bring in a few billion advertising dollars.

So tell me what is different about Google than the “Ma Bell” days of yesteryear?  Google has the cash to buy pretty much any start-up it wants.  Google has the brain power to create pretty much any product it wants.  Google has and wants it all.  Or does it?  Google is still a company.  The larger the company the more difficult it becomes to maintain a cohesive core business.  The more difficult it becomes to truly allow creativity and innovation within.  The more difficult it becomes to maintain quality and support.  The harder it becomes to truly keep the user’s data and best interest in mind.  Eventually what goes up must come down.  Even the mightiest companies weaken, create spin-offs, and face downsizing.

As much as I love the Google products I am beginning to wonder, how much more diverse can they go before we see some cracks in the chrome?
