What’s in My Bag
Image by phil_g
All the stuff I carry around with me on a daily basis. Although I have a car now, I spent several years without one, so I got in the habit of carrying around everything I might need in my bag. I keep it that way now, so I can just grab one thing and be reasonably sure I’m prepared for anything. I can go from fixing someone’s computer to doing my own coding to killing some time waiting for something to going hiking in the middle of nowhere without having to grab more stuff from anywhere.
Too smart for my own good

I don’t…there’s not a real nice way to put this, but I’m a really smart person. Particularly in imaging systems and how they can talk to each other, or what’s possible with something…that’s my specialty I guess. So when I say I’m smart, I mean in that area. History or geography? Well I once tried to tell someone that the Appalachians were west of the Mississippi (wait…are they??), so you know.
So tonight I was clickin’ away on my laptop, passing time while I waited for institute to start, and meanwhile I got to listen to a whole business meeting between these chaps. Now here’s the first problem and my first bit of advice: If you’re conducting a business meeting for something under development…if you want to keep your idea under wraps, don’t hold your meeting in a practically abandoned cafe on campus! Now I’m not crazy Steve Jobs level secretive, but I have some ideas and I try to keep my cards…well not toooo close to my chest, but I don’t just hold them out for public view either!
Setting that aside, these gents were discussing plans to develop an app for iOS. A game. A location based game. And therein lies the problem.
The whole premise of the game relies on location, and not check-in location like 4Square, but constant location data.
This is only marginally supported on iPhone.
And it’s a big battery drain.
In the form it was being discussed, I have a really hard time imagining their app being successful, but we’ll see.
So do I jump in and tell them they need to rethink this whole concept? Naaah, that wouldn’t be nice. That would just be me being too smart for my own good.
What’s in my bag (2009 edition)

Every couple of years I take a picture of the equipment I’m regularly using at the time, as a visual record. This is the 2009 shot.
For comparison, here’s the 2005 version: www.flickr.com/photos/karlo/6046403/
(For reasons I don’t understand, the 2005 version remains my most-viewed photo on Flickr. In fact, I had it set to private for a long time so that it wouldn’t keep piling up views.)
I sold the 18-70 and 80-200 a few years back on eBay (partly to pay for the 18-200, which was better for travel.) The 80-200 was a great optic but a dog so far as AF.
Probably the most impressive thing to me in looking at this set is that there are at least 2 or 3 pieces of gear I still use on a regular basis that I’ve owned for 15 years or more. I’ve done similar inventories with my computer purchases – it helps me know what to spend a lot on (monitors) and not too much on (laptops.)
The other thing is how miserable the quality of the 7 megapixel Optio W30 is, even at ISO 200. I really miss my Canon SD850, which made horrible grinding noises when it zoomed but took a darn good picture.

Fixing computers in the Fab Lab.
My one piece of feedback is they don’t have a battery. The electricity here is all run off generators, and several times a day there’s a couple second drop in electricity, which loses everyones open projects and frustrates the students. A small battery which provided continuity would increase the usability a lot.

Offline Google gadgets… useful when laptop runs out of battery.
Google I/O 2009 – Coding for Life — Battery Life, That Is Jeffrey Sharkey The three most important considerations for mobile applications are, in order: battery life, battery life, and battery life. After all, if the battery is dead, no one can use your application. In this session, Android engineer Jeffrey Sharkey will reveal the myriad ways — many unexpected — that your application can guzzle power and irritate users. You’ll learn about how networking affects battery life, the right and wrong ways to use Android-specific features such as wake locks, why you can’t assume that it’s okay to trade memory for time, and more.

Laptop Battery:28876 Sold History In 2009
Yock Electronics is a 6 years laptop battery manufacturer and global supplier.With 28876 laptop batteries sold history in 2009,we will share our experience with customers on how to buy high quality laptop battery.
When you have finally decided to purchase new replacement battery for your laptop you should ensure that the manufacturer has a reliable reputation. If the battery is manufactured by the maker of the laptop then you can rest assured that the battery will be reliable. However, it might come as a surprise to you that most manufacturers of laptops, even the most reputed ones do not manufacture batteries but have an ancillary unit doing so in their name. For instance, if you were to open a genuine Sony battery (not recommended) you will find that he cells inside are manufactured by Toshiba, Exide or some other battery manufacturer. So in the final analysis you are, in fact, buying third party batteries for your laptop. The third party manufacturers of laptops are also buying their cells from the same manufacturers that are supplying the so called OEMs and so is a good bet to buy your replacement battery from. Besides the lower price you will get additional benefits such as an extended warranty and replacement offers. A one year replacement warranty is a must for your replacement battery, so never settle for less.
The other thing to look for when buying a replacement battery is the type of battery. Manufacturers will use many different technologies however, for laptops there are four technologies used. These are Ni-Cad, Ni-MH, Li-Ion, and Li-Poly out of these Ni-Cad or nickel cadmium batteries are a very rare commodity and are being phased out gradually. Don’t go in for a Ni-MH battery if you have a choice between this and a Li-Ion or Li-Poly battery because the Ni-MH battery weighs much more than the rest and have a lower power to weight ratio, meaning it delivers less power than its lighter weight counterparts. Li-Ion and Ni-Poly batteries are the most advanced and last longer. So try for one of these two technologies. Some laptops are designed to use the kind of battery it originally came fitted with, this means if it came with a Ni-Cad battery it must be replaced with a Ni-Cad battery. This is because the internal circuit of the battery must match the laptop hardware for optimum charging and discharging. However, this is not always the case so check with your manufacturer of the laptop if the battery can be interchangeable.
Finally you must study the power ratings of the battery you are buying. Batteries are growing smaller and the power capacity is increasing. Batteries have two ratings marked on them. One will be the voltage and the other Amperes. When buying your replacement battery buy one with the same voltage rating as the old one but try to get a battery with a higher ampere rating. This battery will have longer charge cycles.
Many batteries are rated in watt-hours. This is perhaps the simplest way to rate a battery. The wattage of a battery is calculated by multiplying the voltage by the amperage so a battery with a 14.4 volt rating and an ampere rating of 3600mAh (3.6 Amps) will have a watt rating of 51.84 watts (14.4X3.6 = 51.84).
If the power rating on the battery reads 51.84 watt-hours it means that the battery can supply 1 watt of power continuously for 51.84 hours or 51.84 watts of power for one hour or any combination of the two. No suppose your laptop runs on 17.28 watts (which is pretty unlikely) a 51.84 watt battery will power it for 3 hours. SO divide the power ratings in watts of the battery by the watts of your laptop to see how long the battery will run your laptop.
Sometimes the power ratings in volts and amps on a battery vary. For instance a laptop that runs on a Li-Ion 14.4 Volt, 3600mAh battery may be able to run on a Ni-MH battery with a 9.6 Volt, 4000mAh rating. The Li-Ion battery will be stronger even though the amperage ratings are lower. Here is why:
Li-Ion: 14.4 volts multiplied by 3.6 amps will deliver 51.84 watt hours of power and a Ni-MH battery will deliver 38.4 watt hours of power because 9.6 Volts multiplied by 4 amps will equal 38.4 watt hours. Naturally the Li-Ion battery should be your choice for a replacement battery.
