TapWe’re…

19 Dec 2011 09:57 by Rick

Although they say that everything on facebook is there for ever, in practice the visibility of any one item is very transient. This fantastic rap came up on Radio Free Babylon last week and has already dropped off the front page. I think it is worth preserving so I reproduce it here (with thanks and slightly improved formatting). All credit to the original authors.

We’re reformed. We’re fundamental.
We’re traditional. Experiential.
We’re Shakers. We’re Quakers.
We’re Baptists. We’re Trappists.
We’re Friends. We’re with the Brethren.
We’re addicts. We’re reverends.
We’re insecure. We’re not so sure.
We’re being cured. We’re not so pure.
We’re Charismatic. We’re problematic.
We’re Latter Rain. We feel your pain.
We’re old fashioned. We’re progressive.
We’re laid back. We’re aggressive.
We’re a throwback to the fast track.
We’re with the Jew—and He’s with you.
We’re disciples. We’re students.
We’re careless—and imprudent.
We’re sinners. We’re winners.
The air seems thinner. We’re at the dinner.

Where you’ve been and where you’re gonna be is not for us to see.
What you did and what you’re gonna do is not what qualifies you.
Is it true that we’re just what we perceive—or what we think we believe?
We’re just trying to finish the float—and there’s room in the boat.

TapStuffed for Christmas by FirstBus

2 Dec 2011 17:11 by Rick

Throughout November and December we are replacing our current ticket and MCV machines with new smart card enabled machines.

FirstBus

Actually—no! You are introducing new “Dumb cards.”

The old ones were open season tickets which were validated on first use and then available for 7 or 31 days. I buy a wad of them when they are on discount and use them as needed. The new ones have a start and end date on them when purchased so you have to know in advance when you are going to want them. No late booking of holidays then else lose a chunk of your season ticket.

Anyway, these are only interim tickets read by eye-of-driver as the full network of machines won’t be installed and operational until April (according to the Council) then real smart tickets become available, but I wonder just how smart they will be and in whose favour.

TapTV Licencing for Students

3 Nov 2011 10:46 by Rick

It is as well to make sure you are doing the right thing with your TV licence because the agency is notoriously unforgiving, very hard to convince about unusual situations and can harass you mercilessly. They have recently clarified the requirements regarding internet watching and laptops etc. The relevant rules are….

Watching TV on the internet
You need to be covered by a licence if you watch TV online at the same time as it’s being broadcast on conventional TV in the UK or the Channel Islands.

Your parents’ TV Licence will not cover you while you are away at university unless you only use a device that’s powered solely by its own internal batteries. You must not plug it into the mains when using it to receive TV.

So it looks like you may be able to get away with a laptop without a licence so long as it is either running on battery and internet (no aerial and the charger is not plugged in—that includes not using an external monitor) or you are only using catch-up services. But I suspect it will not be easy to convince them if they turn up on your doorstep. If you use a TV capable for reception as a computer monitor it can be incredibly hard to convince them that you don’t receive programs on it. Make sure there are no internal aerials or cables nearby capable of connecting to a rooftop aerial e.g. provided by your landlord.

You don’t need a licence during the summer holidays
Good news. If you move out of your term-time address for the summer months, you can ask us to give you back the cost of the licence for that time – which could be around £37. (As long as your licence is still valid for at least three full calendar months and you don’t need it again before it expires.)

So remember to apply for a refund when you finish for the year.

TapBT Wi-Fi users beware

1 Nov 2011 14:34 by Rick

The BT broadband offering has a popular feature which allows you to access the internet from your mobile devices even when away from home. When everyone installs their Wi-Fi routers the process simultaneously sets up another Wi-Fi SSID called “BT Fon” (or sometimes “BT Openzone”, and I have seen both at once). With agreement (I think) these are configured so any BT user can sign in to them using their home account details and gain access to the internet via your connection. For privacy, identity and accounting this is kept entirely separate from the home owner’s connection and the only cost to them is a possible bandwidth reduction caused by the extra load. In practice this is a small price to pay for the ability of friends and relations to gain internet access without knowing your security code. You may get a few passers by briefly tapping your connection but they are not going to do it persistently because they have to be BT broadband customers themselves which they are paying for. It may be more of a problem if you live next to a park or café but not too serious.

This all sounds good—you are providing a service for others and in return they provide a service to you when you need it. There are millions of customers and hence millions of potential free Wi-Fi hotspots for you to use. There is security, in the form of an account and password, to verify identity which protects BT’s and the home owner’s interests.

What there is not is any security to protect the mobile user. The catch is that the Wi-Fi hot spot is only identified by it’s name (“BT Fon” or “BT Openzone”)—but anyone can create an SSID called that! So you don’t know if you are connecting to a real BT service or a fake one. This is true with any Wi-Fi hotspot of course, but much more insidious for these because of their ubiquity. There is a sign on process the first time you use one (and even that can be faked) but it is not required for subsequent connections as it is done automatically. For smart phone users it is potentially even more serious. As is pointed out in this Guardian article from April, phones sometimes connect even while in your pocket. O2 iPhones are configured to do this by default because of a partnership between O2 and BT.

BT have known about this problem for some time but have so far declined to do anything about it or even let anyone know. This is disappointing considering that their security team is one of the most respected in the industry.

TapBristol Independents

3 Oct 2011 22:53 by Rick

I have just been introduced to this organisation which is promoting independent shop traders in Bristol. They have produced a series of six recipe postcards, one for each major shopping thoroughfare in Bristol. This is the Gloucester Road one and I have also seen the Whiteladies Road one. Each one has on the back a recipe supplied by locals and which can be easily made from ingredients purchased in a short walk down the road rather than a car trip to Jamie’s or Delia’s emporium. Look out for them in your area.

See my post from July to learn more about this fascinating street.

Tap“PHP Fatal error: Call to undefined function get_header()” error in WordPress

25 Sep 2011 17:27 by Rick

I am getting occasional (3-4 a month) errors in a log file on the various WordPress installations that I support. The full text is

[25-Sep-2011 09:02:01] PHP Fatal error: Call to undefined function get_header() in /home/<ACCOUNT>/public_html/wp-content/themes/<THEME NAME>/index.php on line 1

Doing the natural thing I Googled for a reason but didn’t find much that was informative. Most of the cases reported were where the user had stupidly inadvertently overwritten the root index.php with the one from their theme of the day. The best I found was ardemis who is one step ahead of me.

As he implies, at important step is to stop the message reaching the user’s browser because it reveals rather too much about your web server. This is done by including the call

ini_set('display_errors', 0);

before the get_header();. This makes the message ONLY appear in the log file, which incidentally, can be found in the theme directory. He then goes on to describe a more sophisticated approach which you can read there if it suits your site. But why are they occurring? Is it search engine spiders or hackers probing the depths of your site.

TapWhat’s the game?

2 Sep 2011 17:05 by Rick

We buy houses - Any price, any condition. Call Emma on 07930 ******I first saw one of these adverts at the beginning of the summer. It was scrawled onto a piece of cardboard torn from a box and tied to a lamp-post with string and I thought “they have got to be kidding”. Since then this slightly smarter one has appeared in a similar place and now I have seen a more detailed one stuck to the door of a car which adds “Up to full market value paid. Fast, reliable service. No agent fees.”.

Is this some sort of scam or is it they just don’t like estate agents? At a guess I would say they they were exploiting people who are having trouble meeting their mortgage but I will be glad to be reassured that they are above board.

TapArguments for and against installing MacOS Lion

22 Aug 2011 09:45 by Rick

I had trouble identifying any compelling reason to install the latest version of the Apple Mac OS version nicknamed “Lion” so resorted to reading all the reviews and listing the points. It may come down to going to a store and trying it out.

Pro

Stuff that is likely to work and I would actually use.

  • The usual security and currency stuff.
  • Creation of instant folders for selected content.
  • Filevault2 encryption.
  • Mission Control (Exposé + Spaces).
  • Accented character picker.
  • Resize windows from any corner.
  • Enhancements to Preview application.
  • Signatures to PDFs (if it works with third party cameras).
  • It is cheap.

Neutral

Either things I am not interested in or don’t have the hardware to support.

  • Full-screen applications now integrated and standard. With large monitors full-screen is often a waste of space.
  • Icons are now monochrome. Probably harder to see but no big deal.
  • Launchpad—I put the Applications folder on the Dock.
  • Autosave and version control (some applications). I am not sure about this one, I don’t think I use any applications that support it.
  • Added 9 Sept: Autosave and version control only work to HFS+ formatted drives, not NAS.
  • Resume (some) applications where you left off.
  • Multi-touch gestures (I have no touch pad—should I get one?).
  • AirDrop (Mac Pro has no built in wi-fi so it won’t work).
  • Reversal of scrolling. I’ll get used to it.
  • Facetime (reported no support for third party cameras).
  • Some gestures not supported on magic mouse.
  • (Reported) side swipes are inconsistent.
  • Loss of Rosetta. I never used it.
  • Mail and Calendar enhancements (I don’t use them).
  • Added 9 Sept: Loss of Front Row (thanks Dozer).

Con

Stuff that will hinder me.

  • Loss of grid arrangement of spaces (now desktops). I race around spaces at speed using Ctrl-Arrows.
  • Desktops don’t wrap around end to start as you cycle through them.
  • Desktops are not identifiable except by content.
  • Going full screen creates a new desktop in the list.
  • Inconsistencies with dual monitor support such as full screen.
  • (Reported) difficulty using copy/paste between desktops.
  • Auto-termination of applications which are not being used.
  • Wake on mouse “wiggle” disabled (not sure if this is just for system sleep or monitor sleep as well).
  • Added 9 Sept: Loss of connection to some NAS devices (thanks Dozer). I am informed by Netgear that my ReadyNAS duo should be ok. Not sure about my LinkSys NSLU2.

At the moment the big blocker is a critical application has not yet been ported but that should be ready in a few weeks finding the time. Then…is it worth it?

TapConfused by Apple ID

6 Jul 2011 13:25 by Rick

To operate Apple equipment effectively you need an Apple ID—but the whole process is very confusing. You can login to your account in at least three places:—

They all require the same id and password but each one gives you different information and there doesn’t seem to be any way to manage the account from one place or even to move from one to the other.

But I am also confused about the concept. Are we expected to have one ID (account) each or one per family? If the former then I can’t see how we can take advantage of the offer on the app store to purchase things once and install them on multiple devices. We were better off under the old family-pack idea. What happens if some of the machines (e.g. an iMac) have multiple users who also have personal devices?

If, on the other hand, we are expected to have one per family then what happens when the kids move out (or more extreme cases like divorce)—how can they take their music and apps with them?

What if you buy/inherit second hand equipment; can you transfer the registration? And what happens if you inherit music/apps—after all they would be regarded as an asset on the estate? Or if you marry? I am reading that Apple will not merge accounts.

Does any of this really matter?

Update: 10 August. Some notice is being taken of this problem. A new development is that an Apple ID can only be associated with 10 devices (including computers) at any one time and there must be a 90 day moratorium between switching of Apple IDs on any device.

Update: 8 Sept. Another well though through commentary.
