Downsizing challenge day 2 – little background

John Large Leave a comment

I Thought I should give you a little background into my life & to try and convince you this isn’t a privileged middle class reaction to a lifestyle.

When I was younger I had no money at all. My dad & I lived with my grandmother and we all pitched in as a family. We had one part time wage in the household. We where lucky in the fact that my grandmothers mortgage was paid off in full when my grandad died. So we all lived in a house on one part time wage. To say we had little money is an understatement but we managed and nobody would have been the wiser to our money problems. Read More....

Downsizing (living simply) challenge

John Large 3 Comments

This has been building up for a while now, but the last 2 weeks have been an eye opener & turning point in my life. For years I’ve been striving to prove myself as an adult, to prove success & to an extent wealth. I know that sounds hideous but take a look at your life and tell me you aren’t doing the same. Living towards some social norm of house, car, family, career, nicer house, nicer car, better job. It’s a treadmill.

I looked at my life over the past 15 years and the happiest I’ve been over that time was when I was at University living in a small one bedroom flat and spending on average £40 a week total (with the exception of rent). I had no money but had no money worries. We lived in a small manageable apartment which was cheap to rent, cheap to heat, took about 20 mins to clean and not an inch of the place was unused dead money.

In contrast I now live in a 4 bedroom townhouse with my wife, I have a big driveway, garage, garden, 4 bedrooms, 4 bathrooms (2 ensuite) and I employ 2 cleaners to keep the place tidy. I drive a nice car (Mercedes c230 estate) and generally live well. However I’m crippled with guilt & anxiety. Do I need all this space? Can I afford it? If my business slows down can I keep the house? What if the car breaks and I need to repair it? How about paying to travel around the world, can I afford to do that?

By contrast, when I lived in the small apartment I worried about nothing. I travelled all over the country & the world. Back then I earned less in a month than I do in a few days now, yet I’m now racked with guilt, worry & anxiety. It seems I’ve bought into “what your parents/family think you should be doing” hook, line & sinker. And I’m not happy with it.

I should be able to take weeks or months off at a time with what I now earn in contrast to my university days, yet I find myself putting flights & hotels on credit cards. Why am I doing that when I earn good money? Because I’ve got all the other stuff to pay for. I need to make sure there is enough money in my account for all the direct debits, the huge council tax bills, the massive utility bills. Yet we are still the same couple who lived off a pittance.

After a lot of talking with my wife we have decided to go back to basics. We are moving back to Manchester and selling everything. We are moving to a small appartment and using the money from selling all of our junk to clear our debt. We should be free to travel & explore again. Without running a car we will be £8k a year better off. Eight thousand pounds! We could take 4 months off a year with that saving, or go traveling for months.

I’m going to chronicle this life change over the coming months as it happens. It won’t be easy but it will be invigorating. Wish us luck and let’s say goodbye to the lunacy.

Problems posting comments on blogger from iOS iPad safari and chrome

John Large 34 Comments

My wife is just getting to grips with her new iPad mini. We bought the mini so she could carry it around in her handbag or backpack for blogging. She is a beauty blogger and is always replying to comments, blogging, tweeting and generally interacting with her peers.

After setting up the ipad mini with all her apps we hit a snag. As soon as she tried to leave a comment on blogger blogs she was unable to, due to some seriously bad CSS/JavaScript. A login box pops up on screen but the on load function is knackered. Poor show blogger.

The problem is that the box loads but iOS doesn’t recognise it as a text entry box so you can’t actually enter any credentials. I tried a few workarounds in both chrome and safari for iOS and the same problem kept occurring. No matter what we tried it was impossible to enter text into the box.

I then grabbed my own iPad and fired up opera. As a web developer I have as many browsers as possible installed on all devices in order to test my own code, something blogger seem to have failed miserably in doing. Sure enough opera rendered the login box correctly and allowed us to enters login credentials and leave a comment on blogger blogs.

This kind of workaround is good for those involved in the blogger community as it will allow you to leave comments on your favourite blogs via iOS.

I cannot believe blogger are still having these issues. The majority of traffic I get to my self hosted wordpress blog is mobile browser users so it would be foolish for me to alienate the majority of my readership.

It would be such a simple fix for them to implement, simply have the login box as static content below the comment box on mobile style sheets. Would take me 2 mins to implement and would make commenting accessible to millions of iOS users. I wonder if this affects android users also. Would love to hear.

So if you like to comment on blogger blogs head over to the App Store & download opera. It’s actually a good browser, an old favourite amongst my geeky friends.

Finally folks. If you are serious about blogging it may be time to go down the self hosted route. Your blog can never be deleted, you can have good backups and you never lose all your hard work. There is no service level agreement on these free things and it can be taken down at any time meaning you lose everything. Take back control.

iPad 2 Celluar Data Problems – O2 PAYG

John Large Leave a comment

I’ve had my iPad 2 since it was first released in the UK, thats a couple of years now and since the beginning I’ve been with O2 for my cellular data. this worked really well up until a couple of months ago. Firstly there was a bug with IOS/O2 carrier settings and it was constantly bugging me to update my carrier settings. This finally went away when upgrading to IOS 6.0.1 but since then my O2 data coverage has been shocking.

The ipad would constantly say it was searching for signal, even though my wife’s iPhone on the same network sat next to me had full signal. When I could get signal I was pretty much limited to GPRS. it seems that I’m not the only one with these issues, the O2 forums are awash with those complaining about this exact same issue. I tried downgrading to IOS 5 but still the same problem, which leads me to believe that it’s either a baseband issue (unlikely) or an issue again with O2 carrier settings. Due to the problems I had earlier in the year I would go with it being an O2 issue.

I’ve tweeted them and they where very helpful, I then dealt with them via customer service and they where less than helpful. They gave all the usual advice, reset network settings, restore ipad, fresh restore. None of these things work. They then said it could be the sim, but they wouldn’t just send me a new sim out, I would have to go to a store. This contradicted what customer service had said on Twitter and to be honest i was sick of speaking to them at this point (they even had me polishing the sim contacts!!).

Finally I decided that I would get a pay monthly sim on EE (formerly Orange). My iphone is on contract with Orange and since the Orange-T Mobile merger into EE coverage has been tremendous. A quick visit to the Orange website and my Sim was linked to my iPhone account & being dispatched.

It arrived today, i popped it into the iPad but no data, plenty of cellular signal but no data. I went onto the Orange website to activate the sim & was told the sim is activated already (worrying).

I decided to give Customer Service a call, something I hate doing with orange as the customer service agents are overseas and the line quality & delay are awful. After some jumping though hoops I was told that the sim is now in the process of being activated and should be operational within 4 hours.

What a hassle for cellular data on my iPad 3G. I don’t understand why you can’t just put a 3G sim in the iPad and it will work, why does it have to be a data only, ipad specific sim from your carrier. I even tested this with my contract sim from the iphone. Nothing, doesn’t work at all. It would be so much easier if we had control of our sims again.

So now I wait and hope that after months & months of shaky 3G I’ll have my 3G back. I like to have 3G access, sometimes I want to use it where wifi is unavailable, sometimes the wifi offered in bars & coffee shops is too slow or suffering a fault which cripples productivity.

I’ll update you with the progress of the Orange sim, but anyone with O2 on the iPad suffering from no service, i can assure it it’s the sim. With my new sim I already get full bars, where before I was lucky (very lucky) to get a single bar. It’s an obvious O2 fault as I’m in a great coverage area & couldn’t get signal even in my garden.

Carmageddon for IOS.

John Large Leave a comment

I’ve been meaning to review carmageddon for a long time but haven’t been able to find the time to write it up. I’ve been a fan of carmageddon for years. Since the first release on the PC I can remember my 3DFX graphics card clicking into gear and the game starting up in glorious 3DFX graphics. All crisp and smooth. Friends would watch on in awe, as on their pc the game looked blocky and rubbish and we had super fast frame rates and insane graphics.

Of course we had the version with blood & pedestrians, not the post public outcry version with green blood & zombies. We played this game relentlessly. Unlocking all the cars but never knowing just how to unlock them. You play it enough and it just happens.

I must have committed hours and hours of my life to this game as a youngster and year after year I’ve come back to play it. Most recently, without access to a PC capable of playing the game I’ve resorted to running it virtually on the Mac with various patches and fixes to just run it.

Then, on twitter, I saw that the original team where running a kickstarter campaign to bring this game to modern hardware. So a donation and a little while later I had the game on my iPad. Wow, I’m impressed. The hardware I used to require to run this game was, at the time, cutting edge. This game now runs on my iPad with no fuss & mega frame rates. At first I thought the on screen controls would be cumbersome but you quickly get to grips with them and it’s mega.

This game is like the best trip down memory lane, and unlike most nostalgia, it lives upto your memory. I got the game for free on release day and instantly paid to gain access to the complete set of maps. You can complete a level in this game in two ways. Firstly, you can race a traditional race. Complete all the checkpoints before your opponents and win the race. Alternatively, and always my chosen method, you can hunt down each of your opponents and destroy their cars. I became a master at this as a teen and I’m glad to see I still have the knack.

You earn credits for killing pedestrians, wasting opponents and collecting power ups. These can be redeemed in return for more armour, power and offensive parts in the garage. Get your car upto full bars for each and you are going to storm the opposition.

The game provides a load of maps to play and each race always pans out differently so it’s really hard to tire of. I love it and the iOS port is genius.

I do hope they bring out a mac version as I would love to return to a keyboard layout, but the iOS version means I can sit in starbucks wasting opponents and sipping a latte. Not bad.

The physics in this game are excellent. The power ups are a lot of fun and with infinite possibilities I’m sure you will be hooked too.

One criticism would be the lack of vocabulary for max damage, but this port stays true to the original so I wouldn’t have expected them to add extra vocab.

Buy this game and get playing.

Unrestrict premium 2

John Large 7 Comments

Just a quick post to say I started using Unrestrict premium to enable AirPlay on all apps and to allow streaming of audio & video from apps which normally only allow audio streaming. Many apps including tv catchup & live Streaming apps restrict AirPlay streaming to audio only but this will allow you to stream audio & video to your apple tv 2 or 3 via AirPlay.

The main reason I wanted to get this hack working is so I can stream sky sports f1 from my iPad to the apple tv via sky go. I can now do that allowing me to watch on the tv in the kitchen or bedroom as I don’t have multiroom.

A really good app and well worth the $2 cydia store price tag. I’ve not upgraded to ios 6, not much point on the iPad 2 so I’m not missing that. This is only available on ios5 as far as I’m aware.

Apple TV 1 – CrystalBuntu – OpenELEC

John Large 49 Comments

It’s been a busy week. With the lack of ability to jailbreak the Apple TV 3 and the rising prices of the ATV2 due to it’s jailbreak friendliness I was torn between spending a lot of money on another Apple TV 2 or going down a different media centre route.

I’ve always used XBMC (now Kodi) since it’s birth, even before when it was Xbox Media Player & my family have become accustomed to how everything works. It works wonderfully for our needs & we now don’t have any subscription TV services (granted we download TV episodes but we have a TV license & could watch them for free on our set top box so hardly a crime). We also convert all our DVD’s into .mp4/.m4v/.mkv files so we can watch them without going to find the disk.

I really love the XBMC (kodi) on the jailbroken ATV2 and it’s served me well for almost 2 years, but I have a few gripes with it. Firstly it’s reliant on a jailbreak, which isn’t ideal. Secondly, whilst videos play perfectly due to hardware acceleration available in the ATV2, the menus are certainly not as snappy or responsive as they are on XBMC (kodi) on our macs. This is understandable as the ATV2 is essentially an ipod touch without the screen. Also it tends to lock up using addons such as streaming video addons & can’t handle 720p Xvid or Divx files. So I went on the hunt for an alternative. It came in the form of an original 1st Generation Apple TV.

This box is a low powered computer with a 1ghz mobile intel processor, 256mb ram and a 40GB hard drive (it is available with a 160GB drive but as my stuff is all stored on a NAS it’s not required). It includes a Nvidia graphics chip and a wide array of I/O ports.

As standard the Apple TV is really showing it’s age. It’s slow & can just about display some types of 720p files using XBMC (kodi). As such it is not an ideal candidate for a modern 1080p media centre. However, if you head over to eBay and purchase a Broadcom BCM970012 Hardware HD Video Decoder Card this low powered computer becomes a media powerhouse. I purchased the following card for £14 and it’s a worthy purchase .

To fit the card you open up the case (4 torx screws) and remove the pre-installed wifi card. This will leave your Apple TV with Ethernet only, unless you add a USB wifi dongle which is possible, but for 1080p content I would really recommend an ethernet setup. You then install the Broadcom card in the wifi cards place & you are good to go.

Now there are drivers available for the standard Apple TV software. You will need to use Firecore’s ATV Flash software to create a patchstick. You can then install XBMC (kodi) and the CrystalHD drivers from the new maintenance menu. As I said before the Apple TV is showing it’s age & the native menus are very clunky & slow. This is where 3rd party Linux distros come into place.

You have 2 options, Crystalbuntu by Sam Nazarko or Openelec. I used Crystalbuntu for a good few days & it is flawless, however the installation procedure is a little harder & Sam (the developer) seems to be concentrating support more on Crystalbuntu for Raspberry Pi. I have since switched to OpenELEC 2.0 (RC 1) – 1.99.1 ATV i386 and I’m really impressed.

To install openelec is a breeze. You will need a USB flash drive, I used a Sandisk Cruzer 16GB drive.

Installation instructions for Apple TV are available here.

Installation is a breeze. Just make sure you have the Apple TV connected via Ethernet. The Patchstick will partition the internal HDD and you will lose the native Apple TV OS – no big deal. It will then automatically download the latest available version and install openelec XBMC. This is essentially a highly customised version of Linux with only the required files to boot on Apple TV, and only the required drivers for the hardware. Footprint is a couple of hundred Meg.

Post installation you will have a fast booting & extremely responsive XBMC installation. The Broadcom CrystalHD drivers will be installed automatically & selected for Hardware Acceleration in XBMC.

Now simply add your media sources & build your library. This is a really fast media centre & will play anything I throw at it. I can watch my 1080p blu ray rips with ease & stutter free. Truly a wonderful addition to our media centre collection.

The Openelec install also has various options in settings so you can configure wifi (either built in if you opt not to install a broadcom card, or USB dongle wifi if you so wish).

The openelec install is self updating (set to auto update in openelec settings) & comes with Samba setup so you can access the Media Centre from any machine on your network, making it easy to copy files, access logs, change keymaps or mess with advancedsettings.xml

This truly is a great media centre setup & I cant beleive all in it cost less than an ATV3 for so much more than that box is capable of.

The next mod maybe is to install a larger HDD or even an SSD. I’m also tempted to get a few more Apple TV’s to mod as media centres to replace the ATV2’s I have. The connectivity & openness of the system is brilliant, as is the tiny footprint & speed of the media centre. It’s so far proved to be rock solid. Boot time from power on is around 15 seconds & power consumption under full load is around 23 Watts, measured with a Kill-a-watt. It’s not relaint on Jailbreaks & the Openelec project is constantly improving with each beta & release candidate.

My advice to any XBMC fans it to test this route out. It’s a handsome box, the optical audio out & connectivity is a real bonus & the UI responsiveness makes this one of the most frugal Media Centres I’ve ever built. I intend to build a Raspberry PI XBMC but I’m told the UI is still a little clunky so I’ll be sure to make a few more ATV XBMC’s.

Air parrot for osx – AirPlay mirroring to atv2 & atv3

John Large 1 Comment

Although AirPlay mirroring is slated for release in OSX mountain lion next month, I’ve always found air parrot to be a great way of AirPlay mirroring & want to share this review with you before Apple steal a lot of their custom.

Air parrot allows you to mirror what’s on your mac screen over the network to your apple TV. It will mirror in 1080p if you have the latest apple TV and it also mirrors the audio from your mac. Surprisingly it keeps everything in sync audio wise and is a great way of watching silverlight content such as SkyGo on your TV via apple TV.

Air Parrot allows me to stream legally my content from Sky Go to any room by mirroring what I see on my desktop display. Essentially I can watch all catch up content and some live stations such as sky sports f1 on any tv in the house.

Air parrot is also useful for full screen presentations via the apple TV. You can demo things on a massive screen, or run full screen presentations including video & audio. I’m really impressed with the software, so much so that I bought licenses for each of our machines.

If you have a need to mirror content from your mac, or would rather not jailbreak your atv this is a good way of watching everything from BBC iplayer, ITV player, 4Od and Demand 5 on your apple tv 2 & big screen TV.

I can’t recommend it enough, I love it when a bunch of developers come up with functionality before the big boys, that really makes a day to day impact on your life. I can’t help thinking that Apple have ripped off Air parrot in mountain lion. Let’s just see how good their implementation is.

Until then, be sure to grab a copy of Air Parrot. You can run it in trial mode for 20 mins, and buy a single license for $10. What a bargain. Check it out at Air Parrot

I leave you with some screenshots & a shot of it mirroring of wifi to the TV.

Google Chrome for IOS.

John Large Leave a comment

I can’t believe it has taken such a long time for chrome to appear on the app store for ios. I switched to chrome on all the desktops & laptops a while ago as safari was buggy & a memory hog & Firefox started crashing a lot since they tried to update too much of it.

Chrome on the desktop is great. It syncs all our passwords and bookmarks on all machines, which is a great help when you share hardware like we do. It means that no matter what machine we are using we have all our bookmarks & passwords ready to go.

Now chrome is on ios we share all the same features. You can look at the tabs open on all your machines essentially picking up where you left off, and you can browse all your bookmarks. Granted As of right now Apple does not allow it’s users to specify a custom browser and they don’t allow use of the Turbo Javascript engine that mobile Safari has. But chrome performs very well and if you have Jailbroken (like I have) you can install browser changer from cydia and set chrome as your default. How nice.

To chrome itself, one of the biggest selling points for me is the syncing between my desktop versions and iPad/iPhone versions. It finally gives me a consistent browsing experience across all devices. Saying that, for a first release this is an epic app. They only thing so far I’ve managed to break is a frozen tab, but closing & reopening the tab cleared it right up and the app remained stable.

One of the best features so far is voice search on iPad. Click the microphone icon and speak your search term. As if by magic your search appears in google. Last night I searched for “a list of the best hotels in Amsterdam on trip advisor” and it found the right page with no typos in the search string. I then tested it by saying “how do you get from Manchester to Amsterdam in a car via hull” to which I was presented with a map of the route and a link for P&O ferries for the car crossing from Hull to Rotterdam. I’m impressed. This is a killer addition for me.

Tabbed browsing is snappy & I’ve yet to actually break the browser. Rendering of pages is flawless and overall speeds are good.

By installing browser changer from cydia, and specifying chrome as your default browser (for maps and YouTube also) you receive a seamless integration of chrome into IOS. I’m really excited for the future of this app.

Today it was announced that Google Chrome for IOS is the top app on the app store. It might finally give apple a kick up the arse to develop mobile safari.

Anyway I leave you with a few screenshots of chrome on the iPad. Any questions, fire me a comment, email or tweet me.

OSX Lion SMB Samba XBMC fix

John Large 32 Comments

This is an update to my last post regarding fixing samba in OSX Lion. I have since ditched samba altogether in favour of NFS. NFS is built into OSX as standard & is a very fast unix sharing protocol. It’s quite hard to configure but thanks to a handy OSX tool called NFS Manager it couldn’t be simpler to setup. NFS is now also supported in XBMC and Firecores Media Player for ATV2 so this is a good time to get to grips with NFS & rid your life of Samba once & for all.

Ok First you need to grab a copy of NFS Manager for free & Install. Its available from NFS Manager

Drag it to your applications folder & fire it up.

Once it opens you need to click on share definitions

Click the + sign to add a definition and then use the select box to select your directory/drive to share

If you follow the options in the picture you will have a share accessible to everyone (my network is double firewalled, and the internal subnetwork is on a different subnet & IP range so it’s fine for me to use this). You can also set directories as Read Only but this will stop you being able to delete from within XBMC. This is the simplest setup available & best to get you started with XBMC & NFS sharing.

you may also want to click the show advanced options and select to allow mounting of any sub folder, great for XBMC

you need to set the -N option in /System/Library/LaunchDaemons/com.apple.nfsd.plist as below – this allows you to connect from XBMC (needs to be added to allow Non Root users to connect).

/sbin/nfsd
-N

Once everything is setup you will want to restart NFS for your changes to take effect

sudo nfsd restart
 

Now in XBMC you can add the share. Click add share, and then click on the zeroconf button. Your computer name should appear with NFS next to it, click the your computer & select the share. That is it, you are ready to go. Sharing with NFS is great, buffering is much quicker & directory browsing much snappier. Now you can rid your life of buggy SMB hacks once & for all.

iPad 2/iPhone 5.1.1 Jailbreak absinthe music not working Fixed

John Large Leave a comment

I’ve been having a problem with Music playing on my iPad since jailbreaking with Absinthe on ios 5.1.1. It’s jailbroken so I can install retinapad for iPhone apps & xbmc for plugin development. Music in the built in app wouldn’t play. I Use itunes match and it would show as playing but nothing would actually play & the track time wouldn’t progress. I suspected a corrupt library somewhere, so I fixed it as follows.

1. Close the Music app, then force close the app to make sure it’s not in memory.
2. Go into settings > Music > and disable itunes match.
3. Install Open SSH via Cydia.
4. SSH into your device with the default username of root and password alpine (I use cyberduck to SSH into my ios devices as it’s a familiar FTP style interface over SSH, very easy to manipulate files without terminal).
5. navigate to /private/var/mobile/Media/iTunes_Control
6. Delete everything inside the Music folder
7. Delete any file modified recently, all playlists DB files etc from the itunes folder at /private/var/mobile/Media/iTunes_Control/iTunes (You could probably delete everything in the folder as it should be regenerated by ios, but do so at your own risk, perhaps backup all files in this folder first.
8. Once deleted go back to settings & enable itunes match.
9. Fire up the Music app and watch all your music re-download from iTunes match, now click any song and it should play from the cloud.
10. Download any/all tracks you like & enjoy.

I assume also that its the same story if you sync music to your device instead of using match, a DB must be corrupted, probably MediaLibrary.sqlitedb or MediaLibrary.sqlitedb-wal

Below is a pic of the folders I left alone in my iTunes folder, delete as appropriate & test.

Mophie juice pack air for iPhone 4 – review

John Large Leave a comment

I finally took the plunge and invested in an external battery pack for the iPhone 4. Being an iPhone owner since the 1st generation I’m well aware of the iPhones issues with battery life. I’ve managed to change my charging habits so that Everytime I’m sat at the iMac I dock the iPhone, Everytime I’m in the car I charge it via the 12v socket in the car via an adaptor, and whenever I travel I take the powercord with me and plug it into any plug I can find. I’m forever topping up.

This has served me well, but there have been occasions, especially when travelling or visiting cities that I simply can’t keep charging it. I only ever lost power completely once in London, and had to go into the apple store on regents street and charge it in an iPod dock for 30 mins, pretending I was testing the dock. It was tedious to say the least.

Enter the external battery pack/battery case market. These are often expensive & quality can be hit and miss. There are plenty of cheap Chinese ones on eBay but I’d rather not trust them charging plugged into the mains, or sat in my pocket for extended periods. Spontaneous combustion has been recorded in the press.

I finally decided on the mophie juice pack air. For one all the reviews are excellent. The build quality & protective properties are immense. I can’t separate the phone from the case the fit is that snug. And lastly they are endorsed & sold by apple. I figured if I bought it from the apple store if it did blow up or damage my phone I’d have some comeback.

Well I’ve been using it for a month now and I’ve got to say I’m very impressed with it. Given a full charge the juice pack will top up the charge from around 2% into the high 80% to early 90% full range. This essentially almost doubles the battery life of my iPhone. It also means I can tweet, film, photograph and work without fear of running our of battery. I use the iPhone 4 a lot. I now use both the built in charge and most of the juice pack each day. But it does mean I can use the iPhone even more without anxiety.

The mophie juice pack air isn’t cheap at £60 but it is a great addition to my mobile office. The iPad and the MacBook pro both hold hours of charge, enough to get through any day. Now the iPhone can keep up.

The case is quite bulky but you very quickly get used to it, and it actually enhances the ergonomics of the iPhone 4, much easier to hold onto.

The air has cutouts for volume, power, headphones etc and moulds perfectly to the shape of the phone. There is also a micro switch on the bottom controlled by an inline button which when pressed will show the charge level of the juice pack with white LEDs, much like the MacBooks.

I opted for the red version in matt metallic red & silver, but you can get black or white.

I really can’t praise this product enough, and recommend them to all iPhone users.

The only downside is that you can’t easily dock the phone. Charging & docking is done via a micro USB cable supplied. I have loads of them lying around so have one in the car and one on my desktop, but it would have been nice to have some sort of pass through to allow it to be docked in an iPod dock. Given that the case is so hard to remove this is my only niggle.

It is available online from apple & other retailers.
