Ran into a situation today where I needed a tftp server in order to serve files to a hardware device. Normally I would have fired up a Linux system to get the job done but it hit me (again) that I’m using a UNIX operating system and it’s bound to have a tftp server built in. Sure enough I found it hiding on the system but I couldn’t get it to run. After some searching around I found my answer and I thought I’d post it so hopefully someone else will find it.

If you want to run the tftp server issue the following command:

sudo launchctl load -F /System/Library/LaunchDaemons/tftp.plist

This will cause the tftp server to load and stay running until it either crashes or you restart your system. If you want to ensure that tftp is always running issue the following:

sudo launchctl load -w /System/Library/LaunchDaemons/tftp.plist

To stop the tftp server issue the following command:

sudo launchctl unload /System/Library/LaunchDaemons/tftp.plist

To permanently disable tftp issue the following command:

sudo launchctl unload -w /System/Library/LaunchDaemons/tftp.plist

Came across this article talking about progress being made with the new Apple TV in regards to jailbreaking and adding new functionality. Jailbreaking was recently ruled as legal. I think this is a big win for consumers who want to be able to use their hardware devices for whatever they want. For example, I think it’s ridiculous that Apple is allowed to force me to join their developer program if I want to write my own iOS application for a device I own. It’s perfectly reasonable that if I want to distribute my software using their App Store platform but beyond that I should be faced with such restrictions.

Also, just because jailbreaking has been deemed legal doesn’t mean pirating software is suddenly legal as well. There are still plenty of other existing laws protecting against that. In the next few months or years I think we’ll see additional clarifications with the DMCA and jailbreaking. For example, although the iPhone was specifically mentioned in the ruling, I actually don’t think it should be ok to jailbreak an iPhone for security reasons as it pertains to the cell phone network. The iPhone is part of a bigger infrastructure that is not owned and operated by the owner of the phone and in that case it’s a lot like a business PC being connected to a business network. At the same however, such a ruling will hopefully coerce Apple into providing a toggle on the phone allowing end users to install software outside of the App Store. This would satisfy what some end users want while still protecting the security of the cellular network.

Xmarks has decided to close up shop because it can’t find a way to make any money. Sad to me because it’s a service I use everyday and is honestly something I’d probably pay for because it works across all browsers on all the systems I care about. Although it is possible to use your own server as an xmarks sync server this is really only a stop gap measure because the plugin is going to need to be continuously updated as new browsers are released. The only answer then is for someone (are you listening Google?) to buy it out or for the team to release it as an open source project.

Ran into an issue while trying to get 64 bit Coldfusion running on Snow Leopard. Somehow Adobe’s installer can’t deal with the fact that the java binaries are symlinked in OS X so you have to manually remove the symlinks and then copy the binaries over. This page documents how to do it. The only thing I did differently is instead of simply deleting the symlinks I created a directory and moved them into that. This way I can restore the system back to normal.

Microsoft celebrated the RTM of Windows Phone with an incredibly awkward mock funeral for iPhone and BlackBerry. Apparently Microsoft is either not worried about Android or they don’t think Windows Phone 7 can compete with it. Either way, claiming to have buried the competition before the general public actually has Windows Phone 7 devices is a bit premature and I really hope it doesn’t mean Microsoft thinks it can now just sit back and relax.

AppleInsider is running a story about a possible iPhone 4 launch on the Verizon network in 2011. This seems to jive with a bit of information from I got from a Verizon worker on the roll out of LTE beginning sometime in the end of 2011 or beginning of 2012. In fact, towers in the Fargo ND area are being upgraded to LTE capable equipment right now. I have my doubts we’ll see a CDMA only version of the iPhone on Verizon’s network and I am betting on a simultaneous iPhone and LTE launch. iPhone being the first LTE capable phone on Verizon’s network would be big marketing win for both the iPhone and Verizon.

Since Steve Jobs came back to Apple there has been one thing Apple has done that nobody can really argue. Innovation in the PC industry. While everyone, including Apple at the time, was producing boring looking beige computers Apple decided to completely rethink how a computer can look and introduced iMac. Love it or hate it, the iMac was completely different than anything else at the time and soon other manufacturers tried to add some amount of flair to their PC lineup.

Skip a head a few years later and Apple did it again. While everyone else was basically creating incrementally different smart phones in 2007, Apple simply destroyed how everyone assumed a smart phone should look and work by bringing to market iPhone. They made it far easier, intuitive and beautiful and from that moment on, they made it so that any phone on the market that didn’t have a touch screen or had a touch screen that required the use of a stylus was simply awkward and outdated.

Apple’s most recent market disruption was none other than iPad. During the summer prior to iPad’s release the netbook craze was in full swing. Just a year later there are reports that sales on netbooks have slowed considerably and some reports even show netbooks are losing out because of iPad.

At iPads reveal in January of 2010 Steve Jobs quipped that netbooks weren’t better at anything, they were simply cheaper laptops. Many people argued that netbooks were most useful for consumption and were never really meant for creating content. Yet netbooks looked and worked just like any other ordinary PC. Apple changed this by creating something that looked and worked nothing like a PC. Note too that iPad was the first tablet device on the market. Microsoft has been trying to get consumers using tablet PCs for years but I don’t think anyone could argue they’ve been anything near the run away success that Apple has seen basically over night.

The inspiration for my post comes from Marco Arment’s recent post. He also poses the interesting question of, “How do you think the subcompact, inexpensive computer category will look in three years?”
