iPhone 4s

Apple iPhone 4s
The Android smartphone that I used every day for work eventually failed. It was fine as a tiny tablet but no longer worked for phone calls. When word of this reached our service director he called me into his office and opened a desk drawer full of "gently used" Apple iPhones and dug out an iPhone 4s. One or two people in my department use iPhones so it seemed likely that I'd be able to find the apps to do my job and I thought it would be an opportunity to try out an iPhone and iOS.

The phone itself seemed nice enough, though the glass back seemed ridiculous because the phone slid around like Bambi on a frozen pond until I found a nice orange case for it. The single button at the bottom of the screen confused me a bit: I'd poke at it like a caveman, wondering why it didn't behave like the back button on Android. A colleague took pity on me and explained that this was the "home button" that would (logically enough) take me back to the home screen. A double-press takes me to a task list that lets me kill things off.

The phone's battery life is abysmal. I have to plug it in every few hours or it craps out, leaving me without a connection to the office. I've heard that iPhones have weak batteries but batteries do age with use, so perhaps it's not fair to judge them all by this one example. I have been pleasantly surprised by how fast the user interface feels and the stability of the apps that I've tried so far. I wonder whether iOS applications are built against cleaner, faster (and fewer?) libraries.

Unlike the Android phone I'd been using, the iPhone 4s doesn't support "4G" LTE speeds. For most of what I do that's not an issue: I just have to wait a bit longer for downloads when I'm not on WiFi. I was able to find iOS equivalents to most of the apps I use and I was pleasantly surprised that Google apps like gmail and Google Hangouts were available for the iPhone. The calendar app won't sync against the MS Exchange account that tells me where to go every day and nobody seems able to figure out why. Because of this I have to bother a friend in the office to have him read Outlook to me. We're high-tech like that.


Server Software

(HP ML110 Server)

Today I have a server to repair or perhaps rebuild. It's an old HP ProLiant ML110 G4 that we bought new over a decade ago. It has a dual-core Intel Xeon processor and just 2G RAM but with NetBSD and Samba that's probably still adequate for a simple file server. I'm told it won't power up, so perhaps it just needs a new power supply. If the problem is more serious I'll have to find another server and reach for the backup tapes.

Recently I've considered OmniOS as a server operating system. Like NetBSD it's deliberately minimal. One possible advantage is its support for ZFS (yes, I know we'd need more RAM). Something that puts me off OmniOS though is an apparent lack of documentation. It seems to be built with the assumption that the server admin already knows Solaris or OpenSolaris and most of my SunOS experience dates back to when SunOS was a BSD.

There are some other alternatives to unix: I could try Linux or even Windows Server. I'll probably test these at home but NetBSD has been very stable for us so I'll stick with that for the production server. I'm a firm believer that "if it aint broke, don't fix it". The hardware's broken though, so let's hope I can fix that.



(Nissan Leaf)

I would like an electric car, partly because of the rising price of petrol. My previous job was about 30 miles away and a Nissan Leaf would have coped with that commute even if my workplace had no provision for charging. My current job has me working in the field and there are days when I drive 200 miles or more. Today reminded me why I can't buy an electric car: I had no time to stop and charge, even for a half-hour top-up. Another concern is the annual cycle of very cold winters and very hot summers. I suspect that might impact the lifespan of the battery.

Driving home I passed one of the filling stations that sells E-85. I've heard some debate about whether its reduced fuel economy offsets the lower price. I'm told it burns a bit cleaner though and it would reduce the amount of fossil fuel I get through every month. Sadly none of the nice little cars that interest me (Chevy Spark, Nissan Note etc.) have the "Flex Fuel" badge that tells me they can drink it.
