BlackBerry (by alaric)

Many moons ago I did some work writing apps for BlackBerries. I liked the things at the time; they seemed to be well-built, both from the hardware and software angles.

So when my mobile phone contract came up for renewal (meaning I can get a free new phone if I sign up for another two years), with my existing phone falling to bits and rather crashy, I was pleased to find that I was eligible for a free BlackBerry 8520!

The device is a nice evolution of the BlackBerry I was using back in 2004 or so; rather than the thumb-activated scroll wheel we now have a two-dimensional scroll thing that works like a trackball, but seems to really be the innards of an optical mouse, set up so it sees my thumb moving over a small plastic window. This works well, takes up little space, and has no moving parts apart from the click action when it's pressed in to select something. The one downside of the new hardware is that my original Blackberry had a reflective LCD; it had an optional backlight, but spent most of its time with it switched off, simply reflecting the light incident upon it (in colour!). This didn't make for vibrant, saturated, hues in photos, but it did save a lot of power, and meant that the screen was highly readable in the brightest sunshine.

There's a few rough edges in the software; my model lacks a GPS, and the supplied maps application lets me enter my home and work locations by typing in an address, then gives me the option to locate that from the current GPS position (which of course fails) or to look up the address - which also fails, claiming the state/province cannot be found. If I just put the postcode into the address and nothing else, it works - but only matches on the first part of my postcode, getting a location that's some distance away in my rural area. I'd like to have an option to choose the location I've scrolled the map to by hand, geocoding that doesn't suck, and no menu options about GPSes when I have no GPS, please.

The mail system tries to auto-configure itself. Which is a blessing, and a curse. I bet it's a blessing for many users, and their IT departments, that they can just enter their email address and password, and have the rest fetched. However, I have a funny mail setup; I have lots of different IMAP mailboxes on the same server, with usernames like "alaric-work". And there happens to be a POP3 daemon listening on the machine that hosts my employer's web site. So when I put in my work email address, it notices that the domain part of the email address has an A record, and it has a POP3 server, and that POP3 server has a user called alaric (which is the user part of my work email address) which it can log in as with that password - so it goes ahead and makes me a POP3 account... with the wrong username and wrong mail server. Which would be OK apart from the fact that there's no way of changing the protocol or username on an existing mail account.

The trick, it turns out, is to deliberately put the wrong password in on the initial setup screen. This causes the POP3 login attempt to fail, and the subsequent IMAP one (in order to be compatible with Outlook's autodetection, it tries POP3 before IMAP!) too; it then says it can't automatically configure me, and asks me to list username and mail server. It then proceeds to guess IMAP somehow (it still didn't ask me, and the machine has POP3 as well as IMAP on it), and pow, my IMAP account is set up.

The Art of Knowledge Unconference (by sarah)

This weekend 12-13 Dec 2009 in Bristol there is an Unconference part of the uncraftivism weekend and I am going to be reading some of my poems that I think appropriate! Like The Programmer's Lament and A Picture of Words.

Me and Alaric are hoping some of you will join us in Bristol 🙂

It looks like a really interesting event so I'm looking forward to it - lots!

BKU2009 on twitter and I think there's some online jabbery stuff occuring. There is also like a talk/culture cafe thing and a lot of free form stuff hence the Un- bit of conference!

On being oddly dressed (by alaric)

Last Friday, I stood up in front of a hundred or so people and gave a five-minute talk on some software I've spent two years of my life writing. However, I wasn't particularly self-conscious about the fact that I was oddly dressed.

For me, clothes are about:

1. Keeping me warm
2. Carrying my stuff

It's not that their appearance doesn't matter to me - I don't want to be wearing shabby or tatty clothes. I don't want to wear garish bright colours. I like my clothes to more or less match, so I tend to choose solid dark colours when I buy myself clothes, as they're easy to look smart in.

But every now and then I get a comment from somebody that I must be a bit weird to go around wearing a podbelt and an assault vest... and when the weather's bad, I got outside in a full-length heavy cloak. Luckily, saying that sort of thing disqualifies people from me being too interested in their opinions, so it doesn't particularly bother me.

I like carrying lots of stuff with me. I'm equipped for every eventuality. When people get things in their eyes, I'm there with a mirror and tweezers. I have the obligatory geek multi-tool, of course. My first-aid kit has brought comfort to many a cut finger. My little lengths of string have jerry-rigged many a repair. I always have a torch, a compass, a pen, a notepad, a monocular, and a laser pointer to hand; so I can navigate, find things in the dark, read small text on a projector from the back of the room (and then point to the thing I'm asking about with the laser). If a button comes off of something, I sit down, take out my sewing kit, and fix it. In my laptop bag is a pouch full of cables and adapters, which has saved the day on many a late-night data-centre emergency. When it's raining so hard that people are cowering in shop doorways, my cloak keeps me dry; at the conference on Friday, when there were no seats left, it folded up tightly and became a low stool so I could sit comfortably. A week or so ago, when I was driving home from London very late one night and became too tired to continue, I pulled into a dark lay-by and slept underneath it, warm and comfortable even when the temperature plummeted before dawn.

I'm not just hoarding gadgets for the sake of it - I do assess the trade-offs of every extra bit of weight to carry around. Weight in the podbelt isn't an issue as it carries very nicely on my hips, I barely notice the weight of it, but space there is at a premium. Weight in the assault vest is more of an issue, since it pulls at my shoulders. I've tried having just a podbelt, but it's not good to wear while sitting down, so I tended to take it off and sling it over the back of the chair, which makes things harder to get at; and I've tried just having an assault vest, but weight was a problem. The current combination means I can keep lightweight things I often need while sitting down (mobile phone, pens, pads, business cards, laser pointer, etc) on me all the time, while weightier things I tend to need more on the move (keys, wallet, tools, first aid gear) in the podbelt. I have optional extra things I add for specific "missions" that I wouldn't want to carry all the time, too - I have a special tool jacket with loops for screwdrivers and the like which I wear if I'm doing DIY in awkward locations, an extra assault vest with more specialist stuff for when I'm busy being a Cub leader, a black lightweight mesh one with large pockets for hiking (the large pockets accept good quantities of food, GPSes, and the like), a water flask that goes on the podbelt, and a spare podbelt pouch that I'm going to assemble a survival kit in: emergency rations, a survival blanket, that sort of thing.

When I've explained this to people who question the amount of stuff I carry, they say "But what are the odds of all these things happening?". But they happen all the time! So I'm happy being prepared for anything... it makes life a lot less stressful. My clothes and their pockets become an extension of my body; we are, after all, all cyborgs.

A new laptop (by alaric)

To my great displeasure, my shiny MacBook Pro was stolen from the office in London!

So, I grabbed our finance guy and we went down to the nearest laptop shop and picked up the cheapest thing they had in the shop that would meet my needs: a Hewlett Packard Pavilion dv7.

The first step was replacing Windows 7 with something. As I knew I might have some teething troubles with getting NetBSD installed, so might need to return to Windows to get online, I shrank the Win7 partition down so I could run it dual-boot rather than nuking the whole thing. However, it was worse than I feared - the NetBSD install CD wouldn't even boot - the boot loader came up, then complained it couldn't read the kernel.

Not good.

So I burnt an ISO of Arch Linux, which is the closest to BSD in the Linux world. No good, either - GRUB loaded, and couldn't load the Linux kernel. I downloaded the boot.kernel.org nano-ISO (which then boots over HTTP from a central server) and that booted OK; but many of the Linux installers I tried died of kernel panics during booting. I wondered if the difference was that boot.kernel.org had an ISOLINUIX-based installer rather than GRUB; googling for this, I found out that GRUB sometimes has trouble with some CD drives, and as such, Arch Linux came with the option of an ISOLINUX-based installer CD. So I burnt a copy of that, and pow, it worked!

I installed Arch Linux, but only in a small partition, still intending to try and install NetBSD via non-CDROM means at some point. I soon had X up, and all was quite well, apart from the fact that my wireless Ethernet module (a Broadcom 4315) didn't work. I found a driver and installed it, and then it was recognised, but it still refused to actually do any wifi. Bah humbug.

On a hunch, I re-downloaded the NetBSD installer ISO and burnt a new CD of it... and it worked, this time! Having wasted most of a week trying to get the first one booting then messing with Linux distros. So I left my Arch partition in place (in case I needed it for anything), and set up NetBSD. Got X working again, copied across the home directory I'd made under Arch rather than redoing my dotfiles, and was happy. Except that NetBSD also didn't like my wireless interface, and it had trouble with the ACPI too, so I can't read my battery status or do a suspend properly. I've found a NetBSD driver for Broadcom devices but I've yet to get it to compile (I think it was developed mainly for the macppc port, or I've just not applied the patch properly). When I get my kernel source tree compiling again I'll have a new kernel that also has verbose ACPI debug messages, which will probably help.

I get Xen working, though; it was painless now that NetBSD's boot loader can do multiboot kernels, meaning I didn't need to mess with GRUB; I just installed the xen tools, and a xen kernel, and a NetBSD/xen kernel, then added the following line to /boot.cfg:

  menu=Xen with 1GiB for dom0:load /netbsd-XEN3_DOM0 console=pc;multiboot /xen.gz dom0_mem=1024M

...and rebooted into a Xen dom0. Setting up some Linux domUs for my work has been more exciting: I downloaded Debian filesystem images and a kernel from stacklet.com, but when I bring it up, Debian complains it can't bring up the Xen virtual network interface - and that it's getting lots of disk errors on the Xen virtual block device (although it can actually read the filesystem without any trouble whatsoever). This may not be helped by the fact that the kernel I downloaded doesn't seem to match the /lib/modules directory in the filesystem image, alas. More work is required.

Still, I'm happy to be back on an X workstation. I liked my Mac, but I was feeling hankerings for open source software, and minimalism. I'm running dwm, dmenu, and remind, joined together with awesome shell scripts. I do miss the intergrated personal-information-management tools in Mac OS X; I want to brew up my own database of people/todos/events/etc in some Prolog dialect (eventually replacing remind), so I can express all the relationships between things that I want ("There is an all-day event on date X called 'Y's birthday' if there is a person P with name Y whose birthday has the same day and month as X", sort of thing) - it'd be nice if it could integrate with Thunderbird's address book, so I may have a look at the format of that (or look into a script to sync it to/from an LDAP directory).

Motivation (by alaric)

When I started working, long ago in 1998 at Internet Vision, motivation wasn't a problem: work was something I did to cheer myself up. This held when I moved over to Frontwire; but when the company abandoned its offices, sacked all of my department apart from me, and I had to work from home back in 2002 or 2003 or so (IIRC), I started to find it hard to get up and start working in the mornings; I realised that working on problems with other people was more of a motivation for me than the fear of being reprimanded for not getting enough work done!

Well, I left that company before long, and freelanced for a while, then got together with some others and formed a company, GenieDB. I can now combine the best of both worlds; I can work from home, in my own environment, while being in contact with my colleagues in our company IRC channel, and working together on problems. I find it hardest when we're all working on unrelated projects, so there's little daily sharing of issues and triumphs, but the level of de-motivation I feel then is small fry compared to how it was when I worked alone!

Nonetheless, since my Frontwire days, various other stresses have appeared in my life, so my base level of motivation is nowhere near what it once was. Carefully managing my morale in order to keep my head above water is an important concern.

Luckily, I made a breakthrough some months ago; for some reason or other I had to be up much earlier than usual, so was up at 8am one day. When I had dealt with the business that required the early morning, it was about 9am, and I didn't need to start work until 10am - so I used the extra hour to go and tinker with stuff in my workshop. It was good. Having had an early morning I was tired that night and fell asleep easily, and having had an hour of "me time", I didn't have my usual restless urge to go and do something fun rather than going to bed.

And I forgot to turn the alarm clock back to its usual time. So the next morning I awoke again at 8am. Except this time, having been to sleep earlier, I wasn't dog tired. So I got up and enjoyed two hours of me-time before starting work.

I was hooked.

Previously, I would wake up knowing I had to get out of bed, get Jean ready for preschool, deliver her there, then start working, spend my lunch break mowing the lawn or other domestic tasks, eat at my desk, work until it was time to go and collect Jean, bring her back, cook dinner, take Jean to bed, then try and catch up on domestic matters (while tired) before going to bed and having trouble sleeping. This not being a particularly delightful prospect, I would often lie in bed far too long, cherishing the ability to just lie there and think, knowing that getting up meant stepping onto a virtual treadmill.

But now I was waking up at eight in the morning, and positively leaping out of bed at the thought of going and doing something fun. I made a rule that, from 8am to 10am, I'd do whatever I wanted; I wouldn't accept requests. I'd get to my desk at 10am, lively and happy. I'd be more tired in the evenings (that extra two hours didn't come out of nowhere), but much less depressed, so I'd get the domestic stuff done sooner and end up spending more time with Sarah once Jean was in bed, then be off to bed in good time as I was getting tired.

My two hours in the morning even gave me time to do things like having showers, which I had previously had to try and fit elsewhere in the day, often ending up going several days overdue!

Even when I'm in London, I woke up at 8am and spent two hours pottering about on my laptop, or going for a walk.

Now that Jean's started school, it's not quite so good - I have to be up at 7:30am to start helping Sarah to get her up, and fed, and dressed, and leave the house at 8:15am to get Jean to the school for 8:45am, but then I'm back home at 9am for an hour of my own before starting work at 10am; I still find it hard to get out of bed knowing I have to do the school run before I can do fun things, and I don't fancy getting out of bed at 6:30am for an hour to myself before doing that 🙂 When Sarah's healthier she might be able to cope with the school run on her own, though, so it might improve yet; she doesn't seem to benefit from starting the day with her own time as much as I do, so that might be a fair trade.

We'll see!
