This continues from my last post, and is mostly a reminder to myself!
My .vimrc file, created for VIM on the RaspberryPi, is also usable on gVim in Windows. It’s the same 2 steps, fetch using Git, and make a symlink (yes you can do that on Windows too)
Open an elevated command prompt (run as administrator)
mklink _vimrc vimfiles\.vimrc Job done!
To VIM or not to VIM. The decades old text editor inspires avid devotion or utter hatred. I fell into the latter camp.
However, now that I’m experimenting with the Raspberry Pi for some hardware projects, it’s obvious I need something with more features than the nano editor. VIM pretty universal, will run in a terminal, or a non-GUI linux, and is undeniably fast editing once the steep learning curve is overcome.
So here are some of notes on VIM – particularly,setting up syntax highlighting with a nice colour scheme – a first step in making VIM palatable to my GUI insticts.
If I’d spent half the time learning VIM as I’d spent trying to customise the colours, I’d be a VIM Jedi already.
I particularly like solarized
On Windows (Putty)
If you want any chance of getting the genuine Solarized colors working in VIM through Putty, the colours in Putty must be changed.
The easiest way to do this is with this reg file which sets up some sensible defaults for Putty, including the solarized dark colours
You will need to recreate any existing sessions to get the new defaults
On The Raspberry Pi
Connect and login using Putty. Your shell session will already have the new colour scheme
sudo apt-get install vim cd ~ mkdir .vim cd .vim mkdir colors wget https://raw.github.com/altercation/vim-colors-solarized/master/colors/solarized.vim vim :e $HOME/.vimrc i (insert mode)
syntax enable set background=dark colorscheme solarized
:wq! (save and close)
Now to add my VIM config to source control, we copy it to the .vim folder and symlink it first
cd ~ mv .vimrc .vim/.vimrc ln -s .vim/.vimrc .vimrc cd .vim git init ls -la (shows hidden files) Configure GIT
git config --global user.name "your full name" git config --local user.name "your full name" git config --global user.email "your email id" git config --local user.email "your email id" git config -l
still in the ~/.vim folder…
git add . git commit -m "Initial commit of my vim configuration"
git remote add origin https://github.com/GregWoods/.vim //had to do a git pull first git pull https://github.com/GregWoods/.vim
git push origin master
My VIMconfiguration is now on github.
To install my Vim Config onto a new server…
cd ~ git clone https://github.com/GregWoods/.vim.git .vimln -s .vim/.vimrc .vimrc
We all love free stuff. Google mail, calendar, contacts, docs(drive), music. All superb free services. Dropbox, SkyDrive, UbuntuOne all add options for free cloud storage. Various other startups offer free services such as notes and picture storage. Free is appealing. But it’s risky, and as our dependency on these services grows, and the costs associated with running them goes up, we’ll see more and more either go to the wall, or start charging.
This week I got stung rather badly by the news that Catch.com – the ultra simple online note taking app, decided to “move in another direction”, and discontinue the service with only one month’s notice. Thankfully I can get my notes out, and import into another service. My problem is that I had spent a year learning, and developing a Windows Phone app that was 100% dependent on their API. Oh dear! That is a lot of wasted man-hours of work.
This is the second time I’ve been caught out by a free online service disappearing. I was an avid user of Google Reader before the plug was pulled. For those companies who keep their products, we are seeing a shift towards a pay model.
Now, I don’t mind paying for stuff to have a degree of certainty that the product will still be around in a years time. My big problem is the cost some of these companies charge. Apple may have introduced the idea of selling apps in bulk for peanuts, but the idea doesn’t seem to have caught on with most companies who are either too greedy, or too busy subsidising the free users, to charge a sensible fee. Dropbox are a prime example. Great product, but at $100/year for 100Gb, it is undeniably expensive. Yet I am more than happy paying Microsoft £32 ($48)/year for the same 100Gb. If I paid for the Premium versions of all the online services which I occasionally use, it adds up to a reasonable sum. Endomondo, Evernote, Dropbox, Google Apps. Most of these services are worth paying something for, but the pricing models are based on users who are using their product as a core part of their life. I don’t, so I won’t pay.
I can’t help thinking all these services would be cheaper if they weren’t giving so much away for free. To attract the customers, a more sustainable model may be to offer the full premium service for free for a long trial period. No more ridiculous 14 or 30 trials which are no use to anyone. No trial should be shorter than 120 days, and for something long term like online storage, make it a year – then make it cheap to sign up a t the end.
So, I got rid of my Kindle DX, which I decided was unsuitable for technical manuals. And due to Amazon’s culling of the product I made a nice profit on it on ebay, and snagged myself a 9″ Nook HD+ (used) for £135. How have I found using it for the last few weeks?
My Use Case
Although I did once find myself jealous of iPad-wielding friends with their fancy games and apps, this soon passed. I wanted a device for reading programming books. One that could handle PDFs as well as ePubs, and one I could look up additional info on the web before returning to the book. In summary, the Nook HD+ is a superb device for this. In some ways, not having access to the Apple or Android app stores is a good thing. There are less distractions. As to value for money, even at it’s full price of £239, it is great value. A little used one on ebay is unbeatable.
- The ‘retina’ class screen resolution
- The large 9″ screen
- Magazine-page-ratio is pretty good for books
- Excellent PDF support, including table of contents
- Good web browser
- Locked down, so little temptation to tinker with it
- ‘Resume reading’ icon always available
- ArticleView on web pages is a nice touch
- Occasional browser bugs. Google Reader doesn’t always render well
- Locked down, so tinkering with it is just more of a challenge (must resist temptation to root it)!
- Most books show with black bars at the top and bottom of the screen. Usable screen is actually 8.2″ for many books
- (The best aspect ratio for programming books is probably 4:3 – an iPad)
- Pinch-zooming-in on a PDF doesn’t shrink those black bars. You instead immediately get a vertical scroll bar. A poor implementation of zoom
- The only icons I use on the home screens are ‘Library’ and ‘Web’. It would be nice to be able to show entire folder contents on a home screen to cut down on navigation taps
It’s a great experience. I’m reading more, which is the real benchmark of success. Being able to quickly flit back and forth between different book pages, and the web is making the learning stick. An e-ink reader is totally unsuited to this form of reading.
How long will I keep it? Unknown. The more suitable aspect ratio of the iPad is tempting, but I will never shell out £399 for a reader. A iPad mini could win me over, if the screen resolution were better. When the iPad mini with retina display comes out – as I’m sure it will – it could sway me to the dark side. The only problem then will be the temptation to use it for 1001 other things rather than catching up on all my nerdy reading.
Sleep appears to be an area of human ‘activity’ which we are still learning about. One observation of sleep is that we can rack up a sleep debt – where we can go a night or two with reduced sleep, and perhaps feel OK for those few days. Eventually the debt must be repaid, or we’ll start falling asleep at the wheel, getting irritable with others etc.
Well, I’ve long maintained that I build up sleep credit. My optimum sleep is likely 7 hours, maybe as low as 6. Mrs Woods seems to need at least 8. So we go to bed somewhere in between – which I suspect is doing neither of us any good. I wake up alert early, fail to get up because the bed is a nice place to be. So I fall back to sleep and the alarm then wakes me in some part of the sleep cycle which you probably shouldn’t be woken from. I feel OK, but not as good as I did when I first woke.
So after 2 weeks with no really late nights, I seem to build up sleep credit. Last night was one of those nights. In bed at midnight. By 1:15am, it was obvious I wasn’t getting to sleep, so I did the correct thing and got up. I started programming on a Windows Phone app I’ve been struggling to devote time to. I made the best progress in a long time. By 4am I wrapped it up and went to bed. I still wasn’t tired, but tossed and turned until 6am when I did get some sleep – though not much.
So in one night my sleep credit has turned into sleep debt. But as long as I don’t give in to the temptation of a post-work nap, or go to bed really early, I should sleep normally for the next week or two.
Maybe I should try polyphasic sleep – though I suspect we’d need separate beds for that!
Sleep is a complex thing. My little ‘sleep credit’ theory could be complete rubbish. Subconscious anxiety, too much caffeine (I admit my body can’t handle caffeine as well these days), a slightly disturbed sleep environment could all have contributed to last nights sleep deprivation. Though the sleepless nights do seem to follow a vague pattern.
