Not the End of an Era: the continuing life of a 2009 MacBook Pro

The 2009 MacBook Pro's days are numbered. As you likely know by now, the 2009 MacBook Pro will not be supported by Mac OS Sierra. I have one of these beasts, and it is a wonderful machine despite 7+ years of heavy use.

But that doesn't mean my 2009 MacBook Pro is dead or will become immediately useless. Quite to the contrary, I expect to use my MBP securely for several more years.

Mac OS X El Capitan will continued to be supported by Apple with security patches for some amount of time. How long? My research shows that Apple supports a deprecated operating system for at least two years after the release of its subsequent operating system.

So if Sierra is released on October 1st, 2016, El Capitan will be supported by Apple until at least October 1st, 2018.

Then what? Well, by rights, most people should no longer use El Capitan as it becomes security-obsolete. But some more technically-minded people might have some options:

Hack Sierra onto the machine. This may extend the security of the machine until Sierra is obsolete, perhaps around October 1st, 2019. No one can promise that Sierra will continue to operate properly on a 2009 MBP, but it could.
Manually patch El Capitan. This may be reasonably possible depending on the security vulnerabilities revealed after obsolescence. For example, there is an NTP security patch that can be manually built and applied to the obsolete Lion.
Install another operating system onto the machine, such as Linux or Windows.
Use the machine in an off-line way. For example, the machine could potentially be used securely if it never shares data with the outside world.

So see? It isn't all that bad. After all, a notebook computer with a 9+ year active lifespan has done well. Even if El Capitan gets all obsolete in the 2018 - 2019 time frame, my machine will continue to be able to provide good service for years to come.

Fixing a SodaStream Jet, part 1: Disassembly Guide

I've had my SodaStream Jet for years, and once in a while something has gone wrong. Disassembly is the first step to repair. Start with this article to see how to disassemble the SodaStream, and then once you have that down, scroll through my other articles to see how I repaired specfic SodaStream problems. SodaStream Jet Disassembly Guide Tools Required Flat head screwdriver Phillips head screwdriver 1. Remove the Carbonator. Duh. 2. Remove the black panel lever The front big black tilt lever needs to be removed first. Removing this panel is tricky, but it isn't impossible. Looking up at the bottom of the black panel, there are two tabs, one on the left and one on the right. These tabs fully secure the panel in place. The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way. Note in the pictures how I approach these tabs with my screwdriver. I usually release the left side first, and then I release ...

Fixing my Wahl 9918 Groomsman Beard and Mustache Trimmer

Not everyone would bother repairing a $25 beard trimmer, but why not fix something for under $5 instead of spending another $25? My Wahl 9918 Groomsman Beard and Mustache Trimmer has admirably performed its beauty duty for many years, but the time came when the battery just wasn't holding a charge any more. Most people would just put the trimmer in the trash and buy a new one, but I figured I could repair my otherwise excellent Wahl and save some money. In fact, even high priced trimmer and rotary shaver brands, like Norelco and Remington, can be easily repaired using a process similar to the one I used to fix my Wahl. Read on to find out how. I opened up the Wahl by popping off the black plastic faceplate with a tiny flathead screwdriver, which revealed two screws. By removing the two screws I was able to easily open up the unit, revealing the guts of the device. Backplate off, Revealing the screws The internals are rather simple: a motor, a...

Sodastream Carbonator Leakage, Usage, and Weight

SodaStream 60L "Carbonator" CO2 cylinders have a specific weight when empty, plus about 410 or so grams for the CO2 they should have when they're "full". A little while ago I went to buy a replacement Carbonator from my local hardware store. The dealer pulled a new Carbonator out of the box and sensed it was lighter than usual. He put the "light" Carbonator in the "empty" pile and sold me a different one. At that moment I concluded that it would be smart of me to weigh both new and empty SodaStream carbonators. Here are the results. Weighing a SodaStream Carbonator - for both Science and Consumer Protection. The dealer told me that sometimes the carbonators leak after they leave the SodaStream filling facility. That means there could be an opportunity for customers like me to get ripped off! The SodaStream cylinders I buy claim to have a net product weight of 410 grams - and that means that a full Soda Stream Carbonator shou...

Macintosh: Upgrading an eMac

It's been a long time since I wrote this article, but the fact remains: The good old eMac can still be useful if you take the simple steps to keep it as good as it can be. All can run Tiger, and most can run Leopard - great operating systems for their day with a bit of useful life. This article describes the procedure I used to upgrade my old eMac, including: Replacing the internal hard disk with a large capacity drive. Increasing the memory for performance Upgrading the operating system Here I'm upgrading a 700 MHz eMac, but the procedure and tasks for upgrading other eMac models should be almost identical. Upgrading versus Replacing My sister's eMac is of the 700 mhz variety, with 256 MB of memory. The machine seemed to be getting "slower", and the original 40 GB disk was becoming jammed packed with photos and iTunes, and within a few months she'd be out of disk space. There were two options to address the problems: upgrade the eMac, or go o...

Robust Installation of an HDHomeRun Networked TV Tuner. 64 OTA channels!

I added an HDHomerun (HDHR) over-the-air (OTA) streaming box to my home network, bringing over-the-air broadcast TV to my computers, phones and tablets. The HDHR is a big upgrade from my previous setup: using a simple "window mount" antenna directly connected to my TV. A TV-attached antenna is good for watching some TV for free, but the HDHR offers so much more flexibility. Figure 0: HDHomeRun on my basement wall My original OTA TV setup was haphazard at best. It was finicky, ugly, and hard for other people at home to use. I would actually tape my antenna to a window whenever I wanted to watch OTA TV. Plus, it only worked on my TV and not with my other devices. I wanted a cleaner and more modern OTA setup. After looking at possibilities, I developed two goals: (1) bring my OTA TV into the modern Internet-connected era, and (2) set it up in a reliable and pretty way so that other family members wouldn't have to fool around with the antenna or anything else. With that,...

Excellent DD-WRT Router for Me: Netgear WNDR3400 / N600

My WiFi performance was suffering, and so I decided to do something about it and upgrade my router. When I say my WiFi performance was suffering, I really mean it: I live in a large high-rise apartment building and there are 100+ WiFi access points visible from my home office. All of the contentious traffic was severely curtailing my WiFi reliability. I was lucky to get 1 Mbit/second throughput. Sometimes I was lucky to stay connected even with my WiFi router in the same room. I decided it was time to go for 5 GHz, which is a WiFi band which is used less frequently and which has a tougher time traversing walls. And of course I wanted DD-WRT support. The set of features I was looking for included: Trouble-free DD-WRT support 5 GHz 802.11n Support Simultaneous dual band capability Inexpensive. Maybe even cheap. For me this means under $50. Under $35 is even better! It sounds like an easy task to bring all this together: A...
