Guide: Bookmarklets

December 1st, 2009

I’ve been using bookmarklets for some years now, they are supremely handy little tools. What is a bookmarklet you ask? Well, according to Wikipedia:

A bookmarklet is an applet, a small computer application, stored as the URL of a bookmark in a web browser or as a hyperlink on a web page. The term is a portmanteau of the terms bookmark and applet. Whether bookmarklet utilities are stored as bookmarks or hyperlinks, they are designed to add one-click functionality to a browser or web page. When clicked, a bookmarklet performs some function, one of a wide variety such as a search query or data extraction. Usually the applet is a JavaScript program.

What do they look like?

Well that depends – basically, just like any other bookmark on your browser toolbar. You can rename them just like any bookmark, move them around, or, as I have done, use a Firefox plugin to allow me to assign an icon to them, so I can remove the name entirely giving me more toolbar space.

I have, added a folder there called Bookmarklets that does nothing but act as a title for the Bookmarkets section of my toolbar. On the right is a non-icon bookmark – this is what bookmarklets would look like without the plugin mentioned above.

What do they do?

Lots of things! Lets explain the ones I use, from left to right:

  • WordPress PressThis – if I’m reading an interesting page I want to share on this blog, simply clicking that bookmarklet pops up a new browser window that opens a new WordPress post on this site. with the article title and link to the article already embedded, ready for me to add anything else. If you’re a WordPress user, you can find this by clicking the Tools menu in your Dashboard.
  • Facebook Share – Pretty much the same as above, but slaps the output on your FaceBook profile instead.
  • Twit This – Pretty much the same as above, but slaps the output on your FaceBook Twitter profile instead.
  • Google Reader – If you use Google Reader for RSS feeds, this one will open the RSS feed of the page you are on in Reader, all ready for you to subscribe to it.
  • ImageShack – opens up a page with all the images on your current page embedded into it. A single click on any of the images rehosts them on ImageShack for you, meaning you don’t have the problem of trying to hotlink images in blog or forum posts.
  • Linked Images – faced with a web server directory listing of images and you don’t want to click on each one to view? This opens them all up fullsize on a page for you to scroll through.
  • Readability – sick of trying to read websites with “hip” and “trendy” designs? Or maybe your eyes just aren’t what they once were. Well, click on this, and it opens your current page in a nice smooth, large font format, with all the guff stripped out.

How do they work?

JavaScript sorcery. In practise? To “install” them is usually a manner of simply dragging a link (from a page like the ones linked above) to your browser bookmark toolbar. To use them, simply click! To “uninstall”, simply right click and delete! It couldn’t be easier!

I use Firefox, is that OK?

Yes!

I use Safari, is that OK?

Yes!

I use Internet Explorer, is that OK?

Yes! With some exceptions, but generally they work fine. You usually can’t drag the link to your Favourites bar, but right clicking and ‘Add to Favourites’ works.

I use Chrome, is that OK?

Yes!

I use Opera, is that OK?

Hurr. Weirdo. Fucked if I know or care. :P

Cars to be started by lasers instead of spark plugs

September 17th, 2009

Cars to be started by lasers instead of spark plugs – Telegraph.

This is a few months old, but hey, LASERS!!!!

Scientists at Liverpool University and engineers at car giants Ford have developed a new ignition system which uses focused beams of laser light to ignite the fuel.

The researchers claim the technology is more reliable and efficient than current spark plug technology and will enable cars to start more easily in cold and damp conditions.

It is understood that Ford, the world’s fourth largest car manufacturer, hopes to put the laser ignition system into their top of the range vehicles within the next couple of years before making it more widely available.

“Lasers can be focused and split into multiple beams to give multiple ignition points, which means it can give a far better chance of ignition.”

Upgrade!

September 13th, 2009

Have just switched this site over to WordPress. Please bear with me as I work through any teething issues. As much crap as WordPress gets given, out of the box I’m fairly impressed with the polish. I’ve imported all my old blog posts with no drama so business as usual for the most part.

Except, if you subscribed to my old Blogger blog, you’ll need to dump that and resubscribe to this one, using the appropriate link in the top right there.

Google Reader Bookmarklet

April 29th, 2009

One for those who use both Firefox and Google Reader. Drag this bookmarklet to your toolbar, and any time you’re on a site with an RSS feed you’d like to add to Google Reader, simply click it and it will transport you magically into Google Reader, with that feed open ready for you to click on subscribe. Nifty.

2am excitement!

October 29th, 2008

So here we were, minding our own business, when all of a sudden a loud bang gave us quite a start. After a bit of investigation, we found this on the TV stand:



Weeeeird huh? Has had our media box (slightly larger than a Shuttle) sitting on it for the last maybe 18 months to 2 years, it’s fairly well supported (in the first pic, you can see the metal support bars under the intact bottom shelf), heat doesn’t seem to be an issue. Anyone have any ideas?

eeeeeeeeeeeeeeeeeeeeBox First Impressions

October 21st, 2008

Picked up one today, gunna use it at work, we have an LCD on a mobile stand that needs a PC to drive it for interactive stuff. That I can bolt this to the back of it is very nice.

Paid $488 ex GST, but they can be had cheaper than that.

Intel Atom 1.6
1GB RAM
80GB HDD
gig-e
802.11b/g/n
Intel GMA 950 video
XP Home

The box! The printed outer layer slips off.

First layer. It also had a lid on top of this bit.

Lift out the eeeBox tray and you can see all the gubbins that come with it.

From left: Stand (required), VESA mount to allow it to be screwed to the back of most desktop LCD’s, AC adaptor and triple prong power cable. Also comes with a UK one too. The bag has the Wifi antenna, a minijack to SPDIF adaptor, manuals and a restore DVD and support/drivers CD. You don’t even get them on a $2k laptop, but on a $500 machine that doesn’t even have an optical drive? Cool.

There it is! Complete with that protective film that I LOVE to pull off.

With adult human hand for scale.

Front, behind the flap. HDD light, power button, SD/MMC slot, USB, headphones, mic.

Rear. Wifi, power, DVI, USB, gig-e, SPDIF out.

First impressions:

Quiet. Very quiet. Fan goes full speed on boot up for a few seconds, but after that, you have to put you ear up to the exhaust vent to hear anything. Nice size…same size as a Wii, but about half the width. Good weight, feels solid.

Feels snappy enough after a brief play, but anything I/O heavy feels a little slow, as to be expected with a 5400rpm laptop drive. Not loaded with crapware! Acrobat Reader and ASUS Update stuff is it.

However, it also ships with something called ‘ExpressGate’. What this is is a linux based quick boot environment loaded with a web browser (Firefox based), Skype, Pidgin for IM and an iPhoto like app. Talks to both the network cards and the SD reader, and also takes up a 3GB partition on the hard drive. Touted as ‘instant on’, it’s more like about 25 seconds from boot to browsing, but hey, it seems nifty enough. I’ve now vaped it since we wont be needing it, but could be useful in some cases. I understand that some standard ASUS motherboards come with this functionality now.

Haven’t tried it to see how it behaves with HD media yet as I’m busy replacing XP Home with something a little more useful, but I will be!

Freeview HD via DVB-T Tuner Card, Part 1

May 13th, 2008

Drive by the need to test out a DVB-T capture card for future use in our HTPC (what’s the point in having a fancy HDTV without access to HD broadcasts right?), and the desire to replace the 14″ CRT TV in my room with something at least slightly more modern, I realised that with all the spare hardware I have, I might as well order up a card and get to it.

Based on my associate Troy’s recommendation, I ordered the Hauppauge HVR-4000 Quad Mode tuner card. I got mine from Playtech, where they retail for a little over $200 inc GST. The spec page listed above tells the whole story, but basically it’s a PCI card with analog TV, DVB-S (satellite), DVB-T and FM tuners. It comes bundled with Cyberlink PowerCinema software, FM antenna, IR receiver and a Microsoft Media Center clone remote. Batteries ARE in fact included.

First up: it’s handy to be aware of some of the local resources available, these will prove invaluable if you run into problems. Geekzone has a fairly busy forum based around DVB-S and DVB-T matters in NZ, with a pretty good signal-to-noise ratio for the most part. Fossie, one of the big posters on the Geekzone forums has put all his info on his blog, and is keeping it updated. This page is very valuable. Cranz has a very detailed site on how to setup MediaPortal. I plodded through it myself, but I link it for reference of others. It’s fairly straightforward if you’re technically minded and have at least some idea of installing and configuring new hardware.

Current test hardware is an entry level box with:

*ASUS M2N-MX SE Motherboard
-nForce 430 Chipset with GeForce6100 VGA onboard
*AMD Semperon 3200+
-1.8GHz
*1GB DDR2
-PC2-5300 @ 333MHz
*80GB Seagate Barracuda 7200.10 SATA HDD
*XFX GeForce 7600GS 256MB Dual DVI+TV PCI-E card
*Philips 190C 19″ LCD @ 1280×1024

Software:
*Windows XP Pro SP3
*Cyberlink PowerCinema (comes with the Hauppage Card)
*MediaPortal
*GB-PVR

Results so far:

*Trying to use onboard video is fruitless. Even cranking it up to 256MB, pointless. You can just get 720p streams to play, but they are jittery as hell. the 1080i of TV3, no way. Usually results in a lockup.

*With the 7600GS – joy, it works, sometimes a very very slight jitter, but it varies from channel to channel. Long and the short of the above two points, you need a card with good H.264 decoding skills.

*PowerCinema wont give me the AAC LATM sound for some reason. Also, it’s a piece of shit, but at least it seems snappier than the other two.

*GB-PVR is a piece of shit. Complex to configure, barely documented, works in a generally stupid way.

*MediaPortal is better, but still a bit tricky to setup, but at least it’s got better documentation and a wider community.

*EPG (Electronic Programme Guide). This is the KILLER app of any PVR. Not knowing when shows are on SUCKS for recording purposes, and most PVR software makes it hard for you to record anything unless it’s in your guide. The advantage of digital TV is that the guide is built in along with the signal, unlike analog TV, which is a stone cold bitch to get a solid, stable guide source for. In fact, it’s unsupported by any official channels here in NZ, and many other places. Thanks Microsoft (and HP/Dell etc) for selling us products we can’t make full use of here! Anyway, I digress….with digital TV, you tell your capture card to grab the EPG over-the-air, and all is well in the world! :D Apart from the fact that the quality and depth of detail varies greatly, but I can only hope this improves with time.

*The UI of all 3 bits of software, at default skin settings, are all ugly as fucking sin. Cheap rip offs of WinMCE, which at least as some kind of slickness to it. MediaPortal is your best bet here with a far wider skin range.

*If you’re installing on Windows XP, you need THIS hotfix. In WinMCE it’s included in a rollup, but not on XPSP2. Note, I used a particular version because doing it the standard way will result in the updated file being replaced by the old version thanks to Windows trying to be secure. :) Once I find the page that told me how to do that again, I’ll link it later.

*Codecs: you need to be able to support H.264 and AAC LATM audio.

Next steps: Trying same DVB-T card and 7600GS in more powerful hardware, recording, and trying to wrangle Windows Media Center (XP and Vista versions), and some kind of linux PVR setup into playing the game. Also, remotes, but this should be trivial. I have both the remote that came with the Hauppage (MS clone), and a genuine Microsoft MCE remote here. That, and I’ve already tried the MS one with MediaPortal, as it has the best support templates it seems.
