TapThe Slug (Linksys NSLU2)

11 Mar 2006 18:24 by Rick

I understand that this brilliant little device has been around for a while but it took me by surprise.

Linksys NSLU2

The spec says that it can add one or two USB2 hard drives to your network accessible from any PC as shared partitions. That is certainly true and it works very well. What is not obvious is the potential of this device; It runs a native copy of Linux from its flash drive and uses Samba to share the drives with Windows. Nicknamed the Slug, quite a lot of people have picked up on it and there is a thriving community of hackers who are turning this cheap little box into all sorts of other things e.g. Web servers, mail servers, media servers, router firewalls, home automation – anything you can do with a decent operating system and a couple of USB ports (or a few other things if you get inside.)

The thing that staggered me when I opened the box was it’s size. How big do you think it is from the picture. I was expecting a mini tower, perhaps the size of a hard back book. The box was smaller than that and when I opened it, the device was the size of the palm of my hand. The slug foot thing is only there to stop it falling over from the weight of the cables.

I have only hit a few snags when installing it and none are problems with the device itself.

  • 10baseT is just not fast enough to drive this thing sensibly, I will have to upgrade my switch.
  • I need some decent backup management software; any suggestions? The device comes with some scheduled job options onboard but I need one driven from the client.
  • Windows Explorer has a problem copying large files nested deeply in folders across the network. It grinds really slowly and watching the lights shows that it goes for long periods doing nothing.

TapEmail Charging Revisited

17:57 by Rick

Prompted by giafly’s comment on my earlier post, which pointed out that AOL had corrected/clarified/backtracked on their earlier statement, I have been taking another look at the issue.

There is a lot of comment around both for and against and, having sifted out the many trolls and flames, there is not much intelligent thinking around that I can see. What I have learned is that the principle of bulk email certification, for that is what this is, is not new. The major difference which has got people all heated is that the model is to charge per item rather than a flat fee. The remainder of the story only concerns AOL customers; that is that suitably certified mail, by a variety of agencies, will be presented as such in their inboxes. That is of no concern to the rest of us. The spectre that this heralds some sort of precedent for all mail, or that uncertified mail will become any less reliable than it is already, perhaps due to neglect of the spam filters, is just not plausible. AOL will continue to serve their customers in the best way that they can because their business depends on it.

TapRat Runs

There was an article on the local news recently about the residents of Barrow Gurney complaining that sat. nav. users were using their village as a short cut to Bristol Airport to avoid the traffic on the A38. Well they are right, but it is not the GPSr users; the Airport Taxis have been using the route for years and have taught the rest of us. The devices are just not clever enough to have picked that way over an obviously more direct route even if it is always busy (with the possible exception of those with congestion avoidance systems and I don’t think there are enough to make that much difference.)

The navigators do need to get better though. I have commented before about some of the silly roads that they sometimes choose based on a line on the map regardless of true conditions to be found there.

This has long been our favourite tea service since we first found a near complete set of 12’s soon after were were married. After that we never saw any again until by chance some friends found a matching dinner service in Guernsey which they kindly brought back for us. Then another big gap until eBay came along and items appeared on there for what seem to be exorbitant prices. I have long wanted to create a page to display this elegant range and finally “finished” it this weekend. The photographs could be better but I have made it a static page so it can be updated as new information becomes available.

TapA question of guilt

1 Mar 2006 09:16 by Rick

The publication today of a new bill “Safeguarding Vulnerable Groups” sets me thinking again about the perilous state of justice in this country. I am not fully conversant with all the rules but am clear on what principles ought to apply. These are

  • No punishment without a conviction, and this includes being placed on a register. Being “known to the police” is not a conviction. (Education Secretary, Ruth) “Kelly announced that in future, cautions for more minor sex offences would be treated in the same way as convictions—both would lead to a ban on working with children.” This is not justice.
  • Punishment in proportion to the crime, which does not include being put on a list for life after a minor misdemeanour. Now a parent may say that they wouldn’t want a pervert teaching their child. But if that conviction was for Indecent Exposure, and when you look at it closely, is actually for urinating in a public place whilst a drunk student, then is a lifelong of vilification on a Sex Offenders Register proportional punishment?

Even in more serious cases, the law generally allows for repentance; it is a requirement for Christian Society. I’m sure that there used to be a system that all relatively minor sentences (I think the figure was less than a five year prison tariff) would be wiped from the slate after a period of time. This needs to be applied across the board for, what hope does an offender have if there is no prospect for them to start again.

“Barred individuals will have a right of appeal.” but that is too late, the damage has been done by then.

Finally, I see from the news report, that “Parents for the first time will be able to check online the barred status when they’re employing a nanny or a music teacher” according to Children’s Minister, Beverley Hughes. This again raises loads of questions about identity, security and accuracy. The new guy upstairs is advertising piano lessons, let’s check to see if he is going to molest our kids, what was his name again?

TapThunderbird are go (just)

25 Feb 2006 16:51 by Rick

I have been meaning to change over from Outlook to Thunderbird email client for a while; mainly because I gave away my copy of Outlook to someone who needed it and I really ought to stop using it myself, but also because I have been inflicting Thunderbird on other people and ought to know a bit more about it.

My initial impressions are mixed; for a basic user it looks great, certainly a lot better than my last experience of Outlook Express (v5). It has all the things that you need and some more if you want to stretch out. For a user like me, who has been on Outlook for some years (even an old version) and has a complex and large email requirement, then it does seem to be lacking in some areas. Perhaps it is just because it is different and will take some getting used to, but I certainly don’t think that it quite lives up to some of the reviews that claim that it is fully featured. Perhaps if anyone knows a solution to any of these problems they could let me know, I wouldn’t be surprised if I just haven’t discovered how to configure it correctly. I have left out the weaknesses that I know to be fixed by extensions.

  • The structure of the mail files is good. Much better in a (standard) flat file format, one per mail folder (rather like OE) than a proprietary database like PST. However I am having trouble managing these folders: you get the choice, for each account, of creating a new top level structure, merging with an existing one or using the Global Inbox in “Local Folders.” There doesn’t seem to be a way of creating a new top level structure independent of the accounts. This may be possible by creating dummy accounts, but is a bit of a hack.
  • Also I can’t find any way to place these structures in a disk location of choice. I want to do this for two reasons—to get data for long term storage off my C: (software) drive and onto my data drive and also to segregate mail by project (which doesn’t match accounts) and to store that mail with the rest of the project data. This is said to be possible by setting the Local Directory for each account but I can’t find it.
  • I have imported all my live mail from Outlook which works ok but with some limitations. All the “follow-up flags” are lost even though both systems have the concept, and all mail comes in “Unread.” Having done this and marked Thunderbird as my default mail client, it doesn’t want to know any more. I can’t find any way to import my archives from detached Outlook mail files.
  • The spell check dictionary is not installed by default – I expected that downloading the British version of the client would have the British dictionary pre-installed. Although it installs like an extension, it has to be done from a login account with admin authority.

On the positive side, the real-time spell checker is great, the integrated spam filter, image and HTML controls and threaded views are good, though I understand they are in the latest version of Outlook too. I’ve not tried the RSS and News readers, multiple Address Books and Message Templates, but they look promising.

Some minor UI weaknesses which annoy more than break the application—

  • The Previous and Next button arrows go left and right but the mail is organised in a vertical list and so should be up and down.
  • There is no button to Resend a mail, you have to use the obscure “Edit as New” function which doesn’t have a button. Even after scouring all the extensions there are still some buttons I would like e.g. print preview.
  • Dragging mail folders around seems to create copies rather than move them. Sometimes using the standard “hold down the shift key” overrides this but not always (I think it fails when moving between top level structures.) Moved folders show as empty until selected.
  • The “Importance” flags don’t exist, but there is an Important Label which is not compatible. The “Follow-up” flags are limited to on or off – there is no “complete” option nor is any target date possible (perhaps because the calendar feature is not integrated as standard).
  • There are a number of different dates which you may want to use to manage mail—Date sent (I think this is the one that is displayed), Date downloaded and also Date received at server would be useful. A problem with using the Date sent is that it can be accidentally or deliberately wrong putting mail in unexpected positions in the list.
  • I don’t really need Drafts, Templates, Deleted and Sent folders cluttering up every top level folder but I don’t seem to be able to delete them.
  • If you switch on View Full Headers, there is no scroll bar and, if there are a lot, then the message itself drops right off the bottom to become inaccessible. This looks like a bug.
  • The mail item window has the subject too small and hidden away. I expect that it is changeable by an obscure option.
  • The address book is a bit limited. It has only provision for two email addresses per person. It could integrate with the main client more closely such as an optional search on the main toolbar and facilities to easily transfer addresses to new mail items made easier. I haven’t found the file yet so don’t know if it is possible to process it using other applications.
  • When reading a lot of mail at the start of the day, the junk mail occasionally gets flagged but not moved to the Junk folder. This has apparently been a known bug for some time. I think it is something to do with checking all accounts concurrently.
  • As it is using the same spell checker as Firefox (SpellBound extension) and OpenOffice.org it would be good if they used the same additional dictionary so I don’t have to teach all three separately about my unusual words.

TapIdentity Verification

Banks are making it very difficult to open accounts these days—something to do with money laundering they say. One of the things that they may ask for is your National Insurance Number. Don’t give it to them! According to a Direct Government webpage

The only people you should ever give your NI number to are:

  • HM Revenue & Customs (HMRC)
  • your employer
  • Jobcentre Plus, if you claim Jobseeker’s Allowance
  • your local council, if you claim Housing Benefit

Entitlement to many benefits depends on your National Insurance contribution record (see ‘Benefits that depend on NICs’ below) so it’s very important not to give your number to anyone else.

Another favourite idea is to put on record some significant questions and your answers so that when you telephone them they can repeat these questions back and so prove that you are who you say you are. This can be very dangerous if the answers to these questions become known (and they are not very imaginitive). The solution is to lie. They will never know if your mother’s maiden name was Smith, Jones or Robinson.

TapVerified email, at a cost

7 Feb 2006 12:14 by Rick

You may have seen the announcement the other day that AOL and Yahoo have a wizard wheeze for solving the spam problem. They will charge non-spamming bulk email senders a fraction of a penny per email to guarantee delivery. dg [link edited 21 Feb] has a good commentary on this pointing out that it would mean the end of email as we know it and seems to be more of a revenue generator than a service for customers.

The catch is that, other than these premium emails, everything else will go into the junk box unless it is from known correspondents. So don’t expect to get mail from someone that you haven’t pre-authorised, such as long lost cousin Gertie or the confirmation that the widget that you just bought is on its way.

TapFavourite Firefox Extensions (3)

3 Feb 2006 10:30 by Rick

This week—LinkToolbar

It allows you to add new toolbar icons which make navigation easier. Users of the full Mozilla suite will be familiar with it as a similar feature is integrated. First it looks for specially inserted HTML elements <link … > which define things like Next, Previous, First, Last and Top. If these are not found (and they are not common) then it gets clever and searches the body of the page for similar sounding manual links. Finally it interprets Up as up one level in the web server directory hierarchy and Top to mean just the domain root. You can put the neat little arrow buttons in any available toolbar space.

Finding this is a bit tricky as maintenance is sporadic. The official web site has version 1.1.0.1 which is suitable for Firefox 1.0.* It was patched for Firefox 1.5 but this copy (1.1.99) can only be found via the bug report. When Firefox 1.5.0.1 came out I couldn’t find a copy at all so I have hacked my own v1.1.99.1 (click to install, right click to download). There is no functional change, I have just changed the maximum permitted version, but it seems to work ok. There is reputed to be a version 1.2 coming out some time but the site has been very inactive.
