iPhone 4 free case: last chance TODAY to get one!





TODAY 30 Sept 2010 is your last chance to order a free iPhone case from Apple - see the Apple iPhone 4 Case Program - if you got yourself an iPhone 4, which I recently did.

The point of course is that the iPhone 4 suffered from signal problems if you held it in the way that most people hold their phones when talking, so in an attempt to firefight the resulting PR disaster Apple started offering free cases which solve the antenna issue.

These blogs have reviews and pics of some of the cases available.

To get your free case, on your iPhone 4 go to the App Store and search for "iPhone 4 case", you may have to scroll a bit in the results to find it. You order the case through the iPhone 4 Case Program app.

Personally, I went for the black Speck PixelSkin HD case (see photos) and I'm very happy with it. Smart, unobtrusive, and it seems pretty tough and hard-wearing.

Only downside is there is no screen protector (but most of the cases don't seem to offer any), and if like me you have feeble fingers, turning the iPhone on and off takes a bit more doing as you have to press it very firmly through the case for it to register.

I wasn't sure from the pic whether dirt might get trapped in the grid lines but luckily the design is such that the grooves are too wide and shallow for that to happen.

Seesaw online TV: review - "TV on demand" will take off





Seesaw from Arqiva is a new video on demand (or VOD) service which lets you watch previously-transmitted TV programmes from (currently) the BBC, Channel 4 (4od) and Five, streamed over the internet to your computer. You can't download anything, it's streaming-only.

Unlike BBC iPlayer and similar offerings from other channels, it isn't restricted to "catchup TV" for recent shows - it went live with over 3000 hours of content, mostly archive TV from the last decade, so there's a wide selection of programmes you can view on demand, from The Apprentice and Little Britain to White Teeth, even past series of Doctor Who from certain years:

No account or login is required. It's free, funded by ads (can't skip, can pause) - note there are ads even for the BBC programmes you watch via Seesaw because the commercial arm of the BBC, BBC Worldwide, did a deal with Seesaw.

If you click on the picture while an ad is playing, it'll pause the playback and open another tab to take you to the website of the advertiser, which is a nice touch. You can easily go back to the previous tab and resume playing.

Seesaw's service is still in beta currently so don't expect perfection, but it does pretty much what it says on the tin. It can be jerky of sound and pic though, depending on the time of day - when lots of people are on the Net, it's not very good, but it's the same with other VOD services like iPlayer.

You don't have to download any software or login, but it's designed only for Firefox, Internet Explorer or Safari on Windows or Mac computers (but from my testing Chrome in Windows works fine, though Opera doesn't).

It's certainly convenient to be able to search several channels' programmes in one place, in case you can't remember which channel broadcast a particular programme you missed.

In terms of content, although Press Association releases say that Seesaw have deals with "independent production companies who produce content for ITV", there's no ITV channel listing. So I'm not sure about ITV content. If they could get all the main free-to-view UK channels or indeed other channels on board too, Seesaw will be one to watch, pardon the pun.

Other similar free online TV services have more channels, on the non-UK front anyway (see my FreeTube free online TV review).

Finding programmes to watch, and watching

As you'd expect you can view by Channel (e.g. just BBC programmes). Or you can view by Category (Comedy, Drama, Factual, Lifestyle, Entertainment, Sport - dunno why it's not alphabetical).

Within each view, certain shows are automatically Featured, but you can browse programme titles alphabetically:

Alternatively you can search, and it cleverly offers suggested titles in a dropdown as you search:

But it doesn't offer searching by name of actor, programme description etc. Hopefully that'll come?

It shows all episodes for the year for a given series and you just click the name of the episode you want to see, then click on the picture to start it playing.

It will "turn the lights down" to heighten the viewing experience. But you can always turn the lights back up:

The controls are as you'd expect to pause, fast forward/rewind with the slider (except during ads), turn subtitles on or off, mute, volume up or down, etc:

And there's a full screen option (Esc to exit):

For trivia buffs

Seesaw uses the technology produced by the ill-fated Project Kangaroo, started up between the BBC, ITV and Channel 4 to set up a joint video on demand service.

Kangaroo was killed off when commercial broadcasters objected and the Competition Commission said No, so Seesaw's parent company Arqiva bought Kangaroo's assets for £8 million in 2009.

Any points to note?

I've mentioned above it works on common browsers on most computers.

It seems to slow down my computer a lot but that could be a coincidence.

Also, there's a bug in that in Internet Explorer 8 (but not Firefox). If you go to full screen view then back to normal size, the controls move downwards "below" the picture so you can't get at anything except the Pause icon; clicking to start the show playing again fixes it, but obviously then you have to watch it again from scratch:

Seesaw's terms say you can only use Seesaw if you're a UK "natural person (i.e. not a company or another business entity)" over 16. So non-UK people can't use Seesaw, though I don't know how they'd detect geospoofing which is pretty easy to do these days.

  • Aside: I've never known a company that could watch TV or surf to a site, except through the medium of a human being, so I don't see the point of banning companies. Do they mean, you can't use it through a company internet connection, or at work or college? If so, why don't they say so? But then I'm weird like that, I actually like to look at Terms and Privacy policies.

Their use of "High, Medium, Low" in the controls (only visible when you first start playback) might confuse some. That's to do with the speed of your Net connection, if you've got a fast internet connection pick High, else pick Medium or Low. I think they should use "My internet connection is: High speed Broadband, Normal broadband, Dial-Up" instead. At least they will provide a warning if you ought to switch to a lower bandwidth option.

There's the usual "Not suitable for under 18" type of age verification which is easy to just click on:

But they do offer a form of parental control, again probably not too tough for kids these days to get round.

The future?

In future, Seesaw intend to offer premium content which must be paid for, e.g. high profile US dramas.

AP quotes Seesaw's controller John Keeling as saying:

"This way of watching television will be on TVs from this year. One of the fastest selling electronic goods is an HDMI cable which connects a laptop to the back of the TV and bingo, you're online and your TV has become an enormous monitor for your laptop."

I think he's right. As I said in my iPlayer review, if you can hook up your computer to your TV, obviously that'll be much more friendly on the eyes and family in terms of watching stuff. Some computers can be connected directly, some need converters. It's easier to do now than it was. If there's demand for a howto blog post on this, please let me know in a comment.

However broadband speeds, or perhaps Seesaw speeds, do need to be a lot faster, more reliable and less jerky if consumers are going to migrate to watching TV over the internet; otherwise, it can be too painful.

I like the semi-interactive feature where you can click on an ad that's showing, to go to the advertiser's webpage. Now that following a consultation last year the UK will be allowing product placement on most TV programmes (to help commercial broadcasters whose revenues are suffering in the downturn), there's scope for Seesaw to set it up so that a viewer can click on the image of the product to go to the webpage for that product!

I must admit I've gone to As Seen On TV before because I really liked a jacket or whatever that I'd seen on a TV show, but I've never been able to find the item I wanted. While on the one hand one doesn't want to condone blatant commercialisation of everything, there's still room to do this sort of "click to buy" thing and stay on the right side of the line.

I predict it'll be coming on YouTube, anyway. Convergence, here we come!

Google offers UK SMEs free website & setup





If you run a UK business that doesn't already have a website, here's a tip: Google London are offering to give you a free business website, including a free .co.uk domain name for 2 years, and "on the spot" help from Googlers to set up your customised site, if you're able to go to their Victoria offices on Thursday 25 Feb 2010 (this is happening between 10 am to 3 pm). Also, you'll get that all important Google goodie bag!

The free site will be set up using a "Getting British Business Online website wizard" (would like to know more about that tool) and no doubt the site will be using Google Apps since Google are involved and they feature Google Docs. It seems there will be help with online marketing too, or at least registering with Google to be indexed: "All sites created will automatically be registered in Google's search engine and so will be listed for relevant queries".

Registration closes at 5 pm London time Monday 22 Feb, that's tomorrow, so if you're interested register now for a spot, and make sure you bring all the business info with you that you'll need on your site.

This is part of the Getting British Business Online campaign launch event - currently it seems that over 1.5 million British SMEs are still without a website and "During 2010 we aim to get 100,000 small businesses online with their first website, for free."

I've not heard much about that campaign to date, though, apart from a Business Link page of 26 Jan 2010; the GBBO site seems more geared towards "partners" than SMEs seeking help, but if you have a non-London business and want help as part of this campaign, try this page and pre-register with GBBO. A small irony is that they're trying to get businesses online who aren't already, but as part of the form for pre-registering, they require an email address as compulsory!!

(Saw the Google link on ECCA).

How to download YouTube, Google Video & other videos





Here's how to download videos from websites to your computer's hard drive for playing when you're offline, using free software. Remember of course we're only allowed to download videos free where we have the right to do that e.g. when the video content is public domain or licensed under Creative Commons.

The easy way

The quickest way I know to download online videos is to download and install the free RealPlayer.

Once you've installed it, whenever you're viewing a webpage with a YouTube or Google Video or indeed lots of other video sites, there will be a "Download This Video" link above the video. Just click that to download the video to your computer.

A "Download & Recording Manager" window then pops up to show the progress in downloading:

When it's done, the "Cancel/Pause" links become "Play" and "Remove" - just click "Play" to play the video! It's been saved to your RealPlayer library.

Tips:

  1. Can't see download link? If you can't see the "Download this Video" link, try hovering over the video and if that doesn't work try starting the video playback.

  2. Preferences etc. Clicking on the arrow to the right of "Download This Video" (marked out in red below) lets you set your download preferences (e.g. which folder on your computer to save downloaded video files to, so you can find them easily later). Or in RealPlayer it's the menu Tools > Preferences, and on the left Download & Recording.




  3. Library. You can also find the downloaded videos later in Windows Explorer by launching RealPlayer and clicking the My Library link, rightclick on any video file and choose "Locate file".

  4. The free version of RealPlayer pops up ads ("messages") from time to time. You can tweak that through Options, Preferences.

The long way to download Google Video

To download Google Videos manually, the tricks mentioned in this blog post no longer seem to work, but the following variation on it does:

  1. Go to the Google Video page of the video you want.
  2. View its source - to do that, in Internet Explorer hold down the Alt key and tap v then release both and tap c to bring up the Source window.
  3. Search in that window for "download_url:", it'll look something like this (with lots of backslashes \ in the verylongstuff bit):
    download_url:'http://verylongstuff'
  4. Highlight and copy the stuff between the single quotes i.e. http://verylongstuff - but without the quotes (rightclick and Copy the highlighted bit, or use Ctrl c)
  5. Click in your browser address bar, or hold down Ctrl and tap l (the letter l) to get there quickly, and in the address bar type:
    Javascript:unescape("pasteTheStuffYouCopiedHere")
    then hit Enter or click Go.
  6. The resulting webpage shown should just display a single long URL in it, starting http://. Just copy and paste that URL from the webpage (not the address bar, but what's shown on the webpage itself).
  7. Use that URL to download the video which may be in MP4 format (playable on RealPlayer etc), e.g. by pasting it into your browser address bar.
  8. If you have trouble downloading it direct in your browser, try this trick I use:
    1. Open Notepad, create a simple basic webpage by typing (or pasting) this in it a new document:
      <html><head></head><body><a href="http://linkToDownload">Link</a></body></html>
      - where of course you insert the URL of the file you want to download instead of http://linkToDownload
    2. Then choose Save and in the File name box type "download.html" with the quotes, choosing the location in which to save your file. (See my previous blog post on how to save files in Notepad easily without .txt extensions.)
    3. Open download.html in your web browser, rightclick "Link" and "Save Target As" to save the file. Often much quicker and more effective than trying to download the file direct via your browser address bar.

Sweetter: see Twitter tweets on any website





To see what people are tweeting about the website you're currently viewing, you can use a bookmarklet / favelet for your web browser, built using Kynetx Apps.

Get the Sweetter bookmarklet free from Phil Windley's blog post (on Kynetx site too).

(For anyone not familiar with bookmarklets, just dragging it doesn't work with Internet Explorer: for instructions see what's a bookmarklet or favelet and how to install or add it, and how to edit a bookmarklet.)

Then, when you're on a web site and want to check out tweets about the site, just click the Sweetter bookmarklet and wait a bit (be patient, it can take several seconds) for a popup that shows recent tweets about the site or blog you're on.

Sweetter makes use of BackTweets and picks up links to the current site which have been shortened via bit.ly or other link URL shortening services too.

Here's what it popped up on clicking the link for my blog.

As you can see, it's scrollable for viewing older tweets (there's a limit to how many it can pick up though) and the X is of course to close it. You can't resize or move it, just use the scrollbar.

It does seem to show some repetition of some of the same few tweets though, I'm not sure why.

A useful and fun tool, and it's free too - so no reason not to go get it!

Free tickets are still available to see the film live, then hear a panel discussion on the idea put forward in the film that:

“Representative democracy is based on the idea that people are thick."

The illustrious group of panelists: Lord David Puttnam, Douglas Carswell MP, Ivo Gormley (director of the film), Rupa Huq, Chair: Catherine Fieschi (director of the British Council).

If like me you can’t make it, you can still watch Us Now:

Convert videos to audio files / other video formats online, free





To convert your movie or audio etc files, a free online media file converter may be the easiest way as it works whether you have a Mac or Linux or indeed Windows - including if you just want to extract the audio sound file from a video on YouTube or another online video service - though if you don't have broadband then obviously it may be a bit slow.

(I've posted before on how to extract MP3 or other sound from video files but that involved only Windows-centric software, and the process can be a bit involved.)

Here are two free online media file conversion services I've tried and suggested to other people who've tried them too, so I know they work.

With both of them, you can enter a YouTube or other video service link to convert the video direct into MP3 or other file formats over the internet; or alternatively you can upload a file from your own computer for conversion and download the converted video, audio or other file.

Media Converter

Media Converter say they support audio formats like mp3, ogg, wav, wma (only decoding supported), and video file formats like 3g2, 3gp, avi, flv, m4v, mkv, mov, mp4, mpg, mpeg, psp (only encoding supported), rm, and wmv, though I've only tried the flv to MP3 conversion myself. (They also say they convert Office document files i.e. text / wordprocessing and presentation documents, spreadsheets etc: doc to odt or pdf, xls to ods or pdf, ppt to odp or pdf, odt to doc or pdf, ods to xls or pdf, odp to ppt or pdf).

It's free only for file sizes up to 100MB, and you pay for the premium service for bigger files.

Media-Convert


Media Convert are more mobile orientated e.g. their "Send File to Mobile" tab enables upload of a file for download on a cellphone, and they have a dedicated mobile host for video or music files.

Supports a wider range of audio files (I won't list them all, see their list of supported file formats, but they include ringtones and .amr and 3gp files as used on mobile phones) and office file conversions (including html, Open Office files, Star Writer etc) - and also compressed or archived file formats like zip, rar, lzh, tar.

Will convert image files i.e. pictures, photos of different formats including gif, jpeg, png, with the ability to resize and compress them, and produce a screenshot of a webpage in your chosen file format (yes you could use your Print Screen key; but it just saves time with converting the resulting file). It even converts pdf to Flash swf.

It will also create a free webpage (with ads, not surprisingly) with a streaming version of the converted file, which you can link to - though I've found it a bit variable as to how well that works. If you want to download the converted file, do that before you try the webpage option, or else it'll vanish and you'll have to convert it all over again.

Up to 150MB size of files converted. Ad-funded. (600MB for their mobile video or music files.)

Personally, I generally prefer the latter as it provides more options (see pic above) in terms of both file conversions (e.g. it will convert PDF source files whereas the former only converts certain formats to PDFs) and ways of presenting the converted files. But as mentioned the webpage streaming option seems not always to work. They're free, so try them both and see which suits you better.

Thunderbird won't open or launch in XP?





Are you having problems trying out the free open source Mozilla Thunderbird email software on Windows XP - in that you can't open Thunderbird at all?

If, when you attempt to launch or open Thunderbird after installation, either nothing seems to happen at all or else the Import box (offering to import your settings from Outlook etc) pops up but then vanishes when you select an option, and Thunderbird still won't come up - well you're not alone.

I had this problem too. Nothing happened at all when I installed and tried to open Thunderbird. Frustratingly, in the Task Manager I could see that Thunderbird.exe was visible on the Processes tab, but not the Applications tab. No amount of killing the process, or uninstalling and reinstalling Thunderbird, would fix it: it was there, but invisible and inaccessible.

Finally, after too much time spent trying to troubleshoot this, I realised what the problem was.

I'd previously tried out Thunderbird, some months ago, but decided at that time that I didn't get on with it, so I uninstalled it. Unfortunately, the uninstallation didn't work very well (so a smack and a spanking for whoever was responsible for that!). It left guff behind that it shouldn't have, and that stuff was messing things up when I tried to install, or rather reinstall, it.

So here's the solution which worked for me (and I hope this tip helps someone else):

  1. Uninstall Thunderbird (Control Panel, Add/Remove Programs).

  2. In Windows Explorer / My Computer, find the Mozilla Thunderbird program folder which should have been deleted but wasn't - on my system it was in C:\Program Files\. Delete that Mozilla Thunderbird program folder (obviously, don't delete Program Files, just the Mozilla Thunderbird folder inside Program Files).

  3. One more Thunderbird folder to delete - on my system it was in C:\Documents and Settings\My User Name\Local Settings\Application Data, real user name blanked out in the screenshot below. (Obviously it won't be "My User Name" on your system, it'll be your username). Nuke that Thunderbird folder too.


  4. Now, go ahead and re-install Thunderbird.

Hopefully it should now work, if the source of your problem was the same as mine. (If not, I don't know what else to try - you could try asking for help on the Thunderbird support forums.)

Geospoofing: PickAProxy review - how to appear to be from elsewhere when browsing






Do you want a website you're visiting to think you're from a different geographic location than your real one?

It's actually quite easy to achieve this "geospoofing", and pretend that you (or rather your web browser) are from the USA (or the UK, if you prefer) well enough to fool the site you're visiting into thinking that's true.

To do this I like the free service PickAProxy.com, which lets you use their proxy servers which they've configured to use the open source Tor anonymity network in a clever way. Their service works with all common browsers: IE, Firefox, Opera, Safari and Konqueror. You can use it for 1 hour a day.

The key is the info given in the right hand sidebar of the PickAProxy site, for example:
  • "To get a selection of proxies that are only in the USA, change your "proxy" settings to point to us.pickaproxy.com and specify port 8125
  • For the UK, use uk.pickaproxy.com and port 8126"
Check out their sidebar for more locations you can spoof, e.g. France, Russia, China...

All you need to do is tweak your browser settings according to their information. And yes, you can tweak IE so that when you're browsing on that, sites will think you're from the USA (or whatever), whereas if you browse via Firefox and haven't tweaked it, sites won't think that and will identify your real general location!

Here's a howto for Internet Explorer 7 (6 will be similar, you may just need to get to the options in a different way).

Internet Explorer - how to geospoof using PickAProxy

  1. Go to the menu Tools, Internet Options, the Connections tab.


  2. If you're on broadband, click LAN settings, outlined in red in the pic above.

  3. You get the following box. Under Proxy server, tick "Use a proxy server for your LAN", then click Advanced:


  4. That takes you to the Proxy Settings. Under Servers, for both Proxy address and Port (and for both types HTTP and Secure), before you go any further make a careful note of what is currently filled in under both HTTP and Secure, e.g. localhost and 8118; you'll need this to revert back later. Then, just fill in the details from Pickaproxy.com according to the geographical location you want to pretend your computer is at, e.g. I'd use us.pickaproxy.com and 8125 to spoof being from the USA, and then OK it.


  5. Best to tick "Bypass proxy server for local addresses" (it's not shown as ticked below, but tick it!) before you tick OK, then OK again all the way back out:


  6. If you're on dial-up, in the Tools, Internet Options, Connections tab just click on the name of your dialup connection in the "Dial-up and Virtual Private Network Settings" section, then click Settings (outlined in yellow in the screenshot in step 1), and then follow steps 4 and 5, and OK everything.

  7. You should change it all back after 1 hour. PickAProxy ask that you limit your use of the service to 1 hour a day - it's free, so I think that's fair enough, but also their service may stop working for you after an hour and you may not be able to browse after that, so you'd better change it back! (I imagine at some point maybe they'll offer a paid-for service that lets subscribers use it for as long as they like?) Anyway, in order to revert to normal, just repeat the above steps, but when you get to step 4, fill in the original settings you'd noted earlier and OK all the way back (my settings were localhost for the address and 8118 for the port, but yours may be different).

How to geospoof using Firefox

With Firefox, you get to the settings differently, but the principles are the same:
  1. Go to menu Tools, Options, Advanced then the Network tab, and choose Settings:


  2. Click "Manual proxy configuration" and fill in the proxy address and port details from the PickAProxy site, depending on where you want to spoof, and again make sure "No proxy for" includes localhost.


  3. To revert after an hour, repeat step 1, but in step 2 the easiest is just to select "Direct connection" at the top instead, and OK everything.

How to geospoof using Opera

I won't include any more screenshots, you get the drift.

I'll just say that in Opera you'd use the menu Tools, Preferences, Advanced, Network, Proxy servers - then tick HTTP and HTTPS, fill in the proxy server and port details and OK everything. And revert back in an hour, etc.

Warning: geospoofing doesn't secure total privacy

Geospoofing is also, in a way, a method of "anonymous" web browsing, an "anonymiser". But only to the extent that it hides your ultimate point of origin from the sites you visit with the browser that you've tweaked.

PickAProxy only hides where you originally came from, not who you are, not the content of your surfing. If you go to a site and then login or fill in a form, or say anything there which indicates your identity or any of your personal details, you won't of course be anonymous to the site!

(Triggered by a recent tweet on Twitter by Broadstuff lamenting his loss of access to the Pandora music service, which now only allows access to people in the USA. Geospoofing may well also work for people in the USA wanting to use the BBC iPlayer. But I should warn you that services like those probably ban geospoofing, implicitly if not explicitly, so you may get into trouble or get blocked or banned etc if you try it for those purposes!)

Free eBook: Zittrain "The Future of the Internet - And How to Stop It"





I previous blogged about Prof Jonathan Zittrain's very interesting and witty talk at the launch of his book "The Future of the Internet - And How to Stop It", which is available to buy in hard copy, or you can get it as a free PDF download under a Creative Commons licence (see my previous post on Zittrain's The Future of the Internet for links).

I've now managed to convert the PDF to an ebook for reading on my Nokia N95 smartphone, as I didn't want to carry the book around with me - it's heavy (hardcover) and it also has some value of the non-monetary kind to me (he signed it with a personal message).

Please feel free to download the eBook (PRC format) of Zittrain's "The Future of the Internet - And How to Stop It" (for those not familiar with electronic books, try downloading and using the free e-book reader software from Mobipocket which is available in many formats e.g. Blackberry, Windows Mobile / PocketPC, Symbian i.e. many Nokia or Sony Ericsson phones, and Palm PDA, you can install it through your computer or over the air - there's even a Windows XP / Vista version and you can manually install it on Mac or Linux too. Tip: on my phone, after launching the MobiPocket Reader, I couldn't figure out how to open the PRC file that I'd stored on my microSD card - where's the File Open menu? Answer: you don't need one. Just find and select the PRC file via your File Manager and it'll automatically open in MobiPocket Reader. I also tried QReader but it didn't work, with this particular file anyway).

It is of course also licensed on the same Creative Commons Attribution Non-Commercial Share-Alike 3.0 terms - free for personal use, basically.

However, it took me the best part of a day to convert and correct it including the images (no kidding - some characters just didn't translate properly so there was a lot of search & replace, otherwise it would have taken 2 days) and I just didn't have the time to do all the fixes, so please note that it's a rough & ready adaptation - while the main substance is there the formatting isn't perfect, and in relation to the footnotes note that:
  • Some of the footnote links are weird - the link text should just be the superscript number for the footnote, but sometimes it extends to other text before or after the footnote number. I fixed the first few, then realised it would take forever to do the rest so I stopped. They're still clickable though, obviously.

  • Some of the footnote numbers, when clicked, don't take you to the right footnote. I suspect this is because links were based on the location of the footnotes in the original PDF and on conversion it kept that, so they take you to the page the footnote was on in the PDF version. Given how many footnotes there are, it would have taken me another week to fix all those. So I didn't. Just bear in mind you may have to scroll down further, even a few pages, when you try to read a footnote - at least you know the number so you can find it.
I still haven't finished reading it (obviously!) so no review from me yet, but I'll put one up as soon as I can. Looking very good so far, which isn't surprising judging by his talk (recording available, see my previous post).

Here's the download link again: eBook (PRC format) of Zittrain's "The Future of the Internet - And How to Stop It".

Shorten URLs via is.gd - free bookmarklet for URL redirection





I've started using the free microblogging (or, for me, more microchatting!) service Twitter a lot more lately, but posting URLs (web addresses) within a tweet takes up too much valuable room when you've only got 140 characters to play with.

If you try to include a URL of more than a certain length in a tweet, Twitter does automatically shorten it using TinyURL, but the catch is that the full length of the original longer URL is still counted towards your 140 characters behind the scenes.

So the best course is to reduce or compress the length of the original URL yourself as much as possible first, then paste that "manually" -shortened URL into your tweet.

URL redirection or compression services

There are several free URL redirection services around that will shorten URLs for you, of which I think TinyURL was the first - certainly it's the best known.

You feed them your long URL and they produce a reduced short URL you can use instead which, when clicked, will redirect the clicker to the original long URL. Usually you can just copy and paste the tinier URL.

These address compression services are probably most often used to produce short URLs which the user can then paste into an email, as often long URLs which extend over more than one line will "break" in emails and then the recipient won't go anywhere on trying to click them - not unless they edit the URL first, which is problematic for novices who don't realise that, and inconvenient for everyone.

URL redirection services have their risks (see the Wikipedia TinyURL article), of which the main one to me is that the service goes down or goes bust and then their URLs will stop working. But personally I'm willing to take the chance where it's for ephemeral use, e.g. in tweets which people are unlikely to look at after a day or two.

is.gd

The main service I use for address shortening is is.gd. Why? Because every reduction in character count helps, and is.gd produces the shortest URLs of any URL shortening service I know of: 5 characters in their base URL, compared with 11 in tinyurl.com, for starters. Hey, 6 characters can make all the difference, if like me you find cutting down verbiage hard work!

Also, I like the fact that they produce the shorter URL in a text box, whereas with TinyURL the shortened URL is displayed in the main body of the resulting webpage. Why do I care? Because my Nokia N95 mobile phone lets me copy and paste text (including URLs) from a text box, but not from a webpage - and believe me when you're using a phone without a full keyboard, copy/paste can save bags of time and frustration.

is.gd bookmarklets

Now is.gd do provide a Shorten with is.gd bookmarklet which you can click in your browser Favorites, Links bar or Bookmarks Toolbar in order to automatically produce their compressed URL for the webpage you're currently visiting (what are bookmarklets / favelets and how to install and use them).

But what if you want to shorten a webpage's URL without having to go to that web page first, e.g. you've saved the link to its URL previously or you can just rightclick a link to it to get its URL?

is.gd don't seem to have produced a favelet for that, so I have. Here it is:
is.gd shorten URLs bookmarklet (which I've also added to my page of useful bookmarklets for bloggers)

Hope it's useful!

(For Firefox users there's a much fancier add-on for is.gd you can get, but it's obviously not available for users of other browsers like Internet Explorer, whereas bookmarklets generally work in all sorts of browsers.)

Extract MP3 or other sound from video files





How to extract just the sound track from a digital video file ("convert" a video file to MP3 etc?)?

There are two easy ways I know of for Windows users, involving free downloadable software:

AoA Audio Extractor


AoA say their extractor turns AVI, MPEG, MPG, FLV (Flash Video), DAT, WMV, ASF, MOV, MP4 and 3GP video files into MP3, WAV and AC3 audio file formats. I've only tried WMV to MP3 so far.

Clearly it's a demo for their paid-for software - they have an arsenal of programs to do stuff with videos and audio files, even DVDs.

It's self-explanatory. Click Add Files, navigate to the movie files you want to add, and select a batch, or just one file if you prefer. Click Browse at the bottom to choose where on your hard drive you want the converted audio to be saved. When you're ready, click Start and go have a cuppa.

Super

Super promises to extract the sound from the above video file formats plus a whole bunch more like FLI, FLC, M2T, MKV, NSV, OGG, QT, RAM, RM(VB), STR, SWF, TS, TRP, VIV and VOB.

It claims to produce not just MP3, WAV and AC3 sound files but also AAC, AMR_NB (for ring tones), AMR_WB, MMF (for ring tones), MP2, MPC (MusePack), OGG and WMA, but I again haven't tried all the variations yet!

The software is free but you have to go through several pages of ads to get to the download link. I don't begrudge them that, and I do check out the ads there. I think it's only fair as the software is free. (I've blogged about Super before in my post on how to convert 3gp video from mobile phones and rotate the video 90 degrees - see that post for screenshot.)

Comparison

Both programs let you convert a whole batch of digital films at one go, rather than having to extract the soundtrack from each one laboriously one at a time. AoA even lets you select and convert to audio just an extract or clip from a video, rather than the full soundtrack.

I tested the software when I converted the videos I shot at the London Girl Geek Dinner about search engine optimisation on 25 March 2008. I converted them to MP3 (hear the extracted audio on the same post), and both Super and AoA Audio Extractor did the job fine. I found that AoA was a little faster, and definitely more user friendly, while Super offers more choice of file formats it can convert to and from (see my tips on using Super - although written in a slightly different context, they should help as they still deal with file conversion).

You pays your money... or rather not, in this case, so why not try both out and see which suits you better.

Tip: before uploading the MP3s, I used the open source multi-platform audio editing tool Audacity to compress and normalise the audio files, which makes the speeches sound much clearer to the listener (I was recording with a digital video camera in quite a noisy pub environment).

Get & review a free Penguin Classic book






Thought I'd blog this fast in case all the books go... you can register on the Blog a Penguin Classic site and if you're fast enough you will get sent a free Penguin Classic book to review. Titles are sent out at random.

In return you have to post a review of the book on the Blog a Penguin Classic site within 6 weeks after you receive it. Fair enough!

It's a simple and brilliant idea. Kudos to whoever thought it up at Penguin or their marketing company. What a superb way to combine old and new media, and garner lots of free publicity to boot. This is how it ought to be done.

Thanks to Rachel Clarke for the tweet!

Free sound samples: OLPC, Freesound





Music & sound clips donated for the One Laptop Per Child (OLPC) project are available for everyone to download, use and re-mix etc, from the sound samples page of the OLPC wiki (via the Creative Commons blog). (On the OLPC itself see this OLPC video.)

There are over 6,500 samples (over 8.5GB) available currently, including sound effects, background sounds or "soundscapes" whether from nature or cities like rain, trains, wolf whistles etc, loops, grooves, drum sounds, voices and all manner of musical instruments - even animal noises like frogs (& humans imitating animal sounds)!

The audio files are made available under a CC-BY licence - which means you can use them freely as long as you credit the author/creator in whatever way they say they want to be credited (e.g. "drum loop by X"). Each sample is 16-bit, WAV, Mono, normalized to -3dB, and provided at 3 sample rates - 44.1K, 22.5K and 16K. (You can convert WAV to MP3 using free open source software like Audacity.)

Another source of free audio clips I like is Freesound, which calls itself "a collaborative database of Creative Commons licensed sounds" - again it's sound effects and sound samples rather than songs. Their samples are available under a different type of CC licence, the Creative Commons Sampling Plus License (must credit the creator, non-commercial re-use, basically). I used a Freesound sample for the (real) Formula One racing car sound at the end of my BarCampLondon3 Segway video that plays as Jason zooms off on the Segway!
