Switch ep. 2: the keyboard

Published September 28, 2008

Well, some bits of this are easy: here’s a MacOS X version of GVim and Vim, which works nicely, is easy to install, and is simply vim/gvim. Great stuff!

But some bits are harder. Remember I was complaining about that silly ± / § key in the top corner of UK/Irish MacBook Pro keyboards? Some investigation reveals that I’m far from alone in this:

‘it fucks up application switching’

‘I hate my MacBook Pro’

a forum post looking for help

another forum post

There are a number of apps that offer key remapping, but for no apparent reason they limit themselves to “popular” remappings only, such as swapping the Control and Caps-Lock keys etc. I presume this is because that was easy to code ;)

The one that does work fully is Ukelele. Watch out though — it comes with a raft of caveats. It’s buggy, at least dealing with my MBP keyboard under OSX 10.5.5; the “Copy Key” functionality doesn’t work, and you need to start using a key mapping file from the Ukelele package, not a system one or one you’ve downloaded, otherwise it’ll silently produce an output file that doesn’t recognise any keys at all. On top of this, each time you make changes, you need to log out and log back in again for them to try them out. (Small mercies: at least you don’t need to do a full reboot, I suppose.)

I’m not impressed by this whole keyboard issue. If you look at photos of the US MacBook Pro keyboard, it’s clear that it doesn’t have the stunted tetris-style Enter and Left-Shift keys that the UK/Irish one does. It also has the tilde key in the normal place, the top left, instead of some bizarre symbol that isn’t even used in this keyboard’s locale, and as Ash Searle noted, when you’re a developer, the # is a hell of a lot more useful than the £ symbol. They’ve basically screwed with a good US keyboard design to bodge in a few extra keys they needed to deal with the tricky European corner cases.

All that would be relatively minor, however, if I could remap the keys to suit my tastes — but it was pretty damn tricky to do that. Key remapping needs to be an easy feature!

I’m still working on the fixed key layout file, but I may post it here once it’s finished to save other Googlers the bother…

Update:: here’s the fixed key layout file:

Irish Fixed.keylayout

Save that to ~/Library/Keyboard Layouts/ , then open System Preferences -> International, select Input Menu, and choose Irish Fixed from the list, and ensure “Show input menu in the menu bar” is on. Close that window, then select “Irish Fixed” from the input menu left of the clock on the menu bar. Log out, and log back in again, and the keys should be sane…

(thanks to Sonic Julez for the MBP key image)

My Trial Switch, ep. I

Published September 23, 2008

As previously noted, I’ve just bought myself a nice shiny MacBook Pro, to replace an old reliable 5-year-old Thinkpad T40, which ran Linux.

Initially, I was contemplating installing Linux on this one too, and dual-booting. But right now, I’ve decided to give MacOS X a go — why not? I find it’s worthwhile updating aspects of my quotidian computing environment every now and again, and it seems everyone’s doing it. ;) I’ll log my experience on this blog as I go along.

(Worth noting that this isn’t my first Mac; back in 1990, I was the proud owner of a free Macintosh Plus for a year, courtesy of TCD’s “Project Mac” collaboration with Apple Ireland. I wrote a great Mandelbrot Set explorer app.)

First off, the good news: the hardware is very nice indeed. It’s light in weight, esp. compared to my T61p work laptop, the screen clarity is fantastic, and the CPU fairly zooms along — unsurprisingly, given that the T40 was 5 years old.

In addition, the multi-touch touchpad is wonderful; I’m looking forward to lots more multi-touch features.

Unfortunately, some of the other hardware design decisions were pretty wonky. By default it’s quite tricky to keep the laptop running with the lid closed — it seems a decision was made to use passive cooling via the keyboard, so once the lid is closed, that heat cannot escape, causing overheating. There’s a third-party extension I can install to allow it anyway, but it’s festooned with warnings to overclock the fan speed to make up for it… ugh. Since I need the ability to be able to remotely login to my laptop from work if I should happen to forget something, or to kick off a long transfer before I come home, this means I have to leave the laptop open permanently, which I didn’t want to do.

In addition, I initially thought my brightness control was broken, since the laptop screen fluctuates in brightness continually. Turns out this is a feature, responding to ambient light — a poorly-documented one, but at least it’s easy to turn off in System Preferences once you know it’s there.

(Unfortunately, a lot of MacOS seems to consist of poorly-documented features that are hidden “for my own good”. The concept of switching seems to involve me abdicating a good deal of what I’d consider adult control of the machine, to the cult of Steve Who Knows Better. This is taking some getting used to.)

On to the software… what’s getting my goat right now are as follows:

Inability to remap keys (CapsLock key, the useless “+-” key, a lack of “spare” keys for scripted actions)

Up in the top left corner of “international” MacBook keyboards, there’s a useless key with a “+-” and double-S symbol on it. I don’t think I’ve ever typed those symbols in my entire life. I want a ~ there, since that’s where the ~ key lives, but for some reason, MacOS doesn’t include keyboard-remapping functionality to the same level as X11’s wonderful “xmodmap”. It seems this third-party app might allow me to do that, or maybe something called ‘KeyRemap4Macbook’?

This Tao Of Mac HOWTO seems helpful on how to support the “Home”/”End” keys, for external keyboard use.

Focus Follows Mouse

This is a frequent complaint among UNIX-to-Mac switchers. It seems that some apps do a hacky version of it, but then you’ve got this inconsistent thing where you lose track of which apps will automatically pick up focus (Terminal, iTerm) and which ones need a click first (Firefox, indeed everything else). Unfortunately, it seems an app called CodeTek VirtualDesktop would have fixed it, but seems to have been abandoned. :(

Programmable Hotkeys

I use a few hotkeys to do quick window-control actions without involving the mouse; in particular, F1 brings a window to the front, F2 pushes it to the back, F12 minimizes a window, Ctrl-Alt-LeftArrow moves a window half a screen left, and Ctrl-Alt-RightArrow moves a window half a screen to the right. Those are pretty simple, but effective.

This collection of Applescript files, in conjunction with Quicksilver, look like I may be able to do something similar on the Mac. Here’s hoping. LifeHacker suggests that the default for minimize is Cmd-M, so that’s what I need to remap from, at least…

This is a big issue — Dan Kulp had a lot of hot-key-related woes, and wound up going back to Linux as a result. Evan reported the same. I like the idea of MacOS, but my tendonitis-afflicted wrists need their little shortcuts; I’m not willing to compromise on avoiding mouse usage in this way.

(by the way, in order to get F1/F2/F12 back, check the “Use the F1-F12 keys to control software features” box in the Keyboard control panel. Thanks to this page for that tip; it has a few other good tips for UNIX switchers, too.)

Upgrades and Software

So, there’s two main contenders for the “apt-get for Mac” throne — Fink vs MacPorts. Fink takes the Debian approach of downloading binary packages, while MacPorts compiles them from source, BSD/Gentoo-style, on your machine. Since I’m not looking at the source, or picking build parameters, or auditing the code for security issues there and then, I don’t see the need to build it — Fink wins.

One thing though — the installer for Fink informed me that I needed to run “Repair Permissions”, which took a while, and found some things that had somehow already been modified from their system defaults, I’m not sure why. This left me slightly mystified. I then was later told that this is now considered ‘voodoo’. wtf.

Mind you, Daring Fireball suggests that the Mac software update are so poorly implemented that they require essentially rebooting in single-user mode, which sounds frankly terrifying. I hope that’s not the case.

BTW, it’s worth noting that IMO, AWN is as nice as — possibly nicer than — the Dock. ;)

Anyway, that’s post #1 in a series. Let’s see how I get on from here. (thanks to Aman, Craig and Paddy for various tips so far!)

AWS event in Dublin’s Digital Hub

Published September 4, 2008

Brian Scanlan mailed me with this blurb, worth blogging for any AWS users in the Dublin area:

  • Are you a software developer or IT professional working in the Dublin area?

  • Would you like to learn more about Amazon Web Services?

Amazon spent over ten years developing a world-class technology and content platform that powers Amazon web sites for millions of customers daily. Most people think “Amazon.com” when they hear the work; however developers are excited to learn that there is a separate arm of the company, known as Amazon Web Services or AWS.

Using AWS, developers can build software applications leveraging the same robust, scalable and reliable technology that powers Amazon’s retail business.

Amazon Data Services Ireland are delighted to welcome Simone Brunozzi (simoneb at amazon.com), AWS Evangelist for Europe, to Dublin, where he will give an overview of Amazon Web Services, including S3, EC2 and EBS, SimpleDB and more.

Tuesday 16th September 2008 at 7pm, The Digital Exchange Auditorium, Crane Street, Dublin 8

Maps and directions to the venue are here. Refreshments will be served.

All welcome – but places are limited, so please sign-up by mailing aws-dublin-event at amazon.com before Thursday 11th September.

I have no connection to this; not even sure if I’ll be going, as I went to the last one anyway and it was a bit short on technical tips ;) . But worth blogging anyway.

Another POS skimming fraud in Galway

Published September 1, 2008

This is a little late, since I was off on holliers when it came to light — Galway News reports ‘hundreds hit by skimming scam’:

The account details of shoppers who used credit or laser cards to pay for their groceries and other items in a number of Galway shops and supermarkets were illegally skimmed by a gang who apparently managed to interfere with the Chip & PIN terminals at the stores’ check-out counters.

The Irish Times story:

However, it has emerged some cardholders had several thousand euro taken from their accounts overseas before they realised what was happening and alerted their card provider. And it is feared that thousands of other customers do not yet realise their cards have been cloned. Garda sources have confirmed the case involves thousands of cards.

The Galway investigation is centred on one large shop in the county. Gardaí believe several thousand cards have had all of their details skimmed, including pin numbers, over the past month. Some of the cards have already been cloned and used in Canada and other countries where, unlike Ireland, chip and pin protective technology is not in use.

In the Galway case […] Detectives are working on the theory that somebody in the Galway shop may have facilitated the card skimming for an Eastern European crime syndicate.

Gardaí do not believe the payment terminals were tampered with. Gardaí have recovered CCTV images of suspects from in-store cameras.

In the past, cards have been copied using very small hand held devices through which a card is quickly and discreetly skimmed at the point of payment. The information is then copied, or cloned, onto a blank card which is then used like a regular payment card.

Skimming devices around the size of a cigarette lighter can store details from thousands of cards.

The payment terminals from the Galway shop have been taken by gardaí for technical examination as a precaution. The Garda Bureau of Fraud Investigation is leading the inquiry.

This Boards.IE thread is a real eye-opener, containing lots of reports from victims of this scam — many reports saying that they suspect it was in Joyces’ Supermarket in Knocknacarra, although one poster reckons ‘there are now over 20 suspect premises in Galway City and outskirts’. blimey.

On a related note — while shopping in my local supermarket at the weekend, I was pleased to note that when I paid with my credit card, I was asked to sign the slip, instead of using Chip-and-PIN. So it looks like at least one retailer is taking additional care.

On the other hand, the thread also notes many cases of skimming which took place from in-store ATMs in small convenience stores — those are very widespread now. eek. :(
