NFC? NFW

As is our custom on a Saturday, this morning my wife and I went out to a local cafe for breakfast. We know the proprietress so I was chatting to her whilst paying for the meal. Part way through the chat, the cafe proprietress tore off the receipt from the POS terminal and removed my …

nokia lumia 1020

I have been a Nokia fan for many years. Like many people, I guess, my first mobile phone was made by Nokia. I have certainly owned more Nokia mobiles than those from any other single company. One of my favourite mobiles (which I still own as a backup) is the 6500 slide. I also still …

blimey that was quick

The cable tester I ordered at around 17.00 yesterday arrived in this morning’s post. And jolly good it is too for such a ridiculously cheap item. As expected, the instructions are amusing but pretty clear for all that. It is easy to use and feels fairly robust, despite the price. Now the results. I am …

blimey that is cheap

David’s comment to my post about my gigabit ethernet upgrade prompted me to look for a cheap LAN tester so that I could check continuity through the RJ45 coupler that had caused me difficulty. It would also be handy to be able to check the box full of old patch cables that I seem to …

slow gigabit ethernet

I have been making some changes to my domestic network of late which I will write about later. However, one of the main changes has been an upgrade from 10/100 switches to gigabit – mainly to improve throughput between my central filestore and desktop machines. For cosmetic reasons (and to keep my wife happy) I …

another good reason not to buy one

Back in November 2011 I wrote about the TP-Link TL-SC3130G IP camera. I had some trouble getting that device to work properly over wifi so I returned it and got my money back. Today, Core Security released an advisory about this device (and several others from TP-Link) about a remotely exploitable vulnerability arising from “hard-coded …

password theft

I have mentioned odd postings to bugtraq before. Today, one “gsuberland” added to the canon with a gem about the Netgear WGR614 wireless router. He says in his post that he has been “reverse engineering” this router. Now for most bugtraq posters (and readers) this would mean that he has been disassembling the firmware. But …

what every iphone needs

I stumbled across this site today when following a link from an email on the topic of reflashing an android tablet with CyanogenMod. The guy who sent the email (to the ALUG list) had bought a generic 7″ android tablet. He was considering reflashing with CM9 and was asking for advice/guidance/gotchas or whatever before doing …

disappointing satnav

One of my hobbies is motorcycling. I have travelled extensively by bike in central and southern europe over many years, but oddly, I have never visited scotland before. I intend rectifying that shortly. When travelling in europe I have always made do with the excellent Michelin range of 1/1000000 (1 cm to 10 km) maps. …

unplugged

A few days ago my sheevaplug died. Beyond the obvious lack of response either over the network or through the USB serial connection, the symptoms (single green LED rather than blue and green LED lit, ethernet LED light steady rather than flashing) were all consistent with a blown PSU. This problem is well known and …

tp-link respond

A couple of weeks ago, I wrote about the problems I had with a TP-Link IP camera. Today I received a comment on that post from a guy called Luke in the TP-Link support team. In that response he apologises for the difficulties I had and promises to investigate further. His response deserves as wide …

do not buy one of these

image of TP-Link IP camera

  Standalone IP cameras have come down in price quite remarkably over the past few years. It is now perfectly possible to get a camera for between £50.00 and £75.00, and this makes them attractive for anyone wanting to set up simple “home surveillance” systems. I bought one recently just to see what I could …

I guess they do it differently over there

nimbus 2000 sheeva plug

I came across a potential new entry to the “slug replacement” competition today in the shape of a 2GHz Sheeva Marvell based plug computer by Ionics called the Nimbus 2000 (all the company’s products seem to be named after cloud types – wonder why). In addition to that rather fast ARM CPU, this little beast …

unplugged

My earlier problems with the sheevaplug all seem to have stemmed from the fact that I had installed Lenny to SDHC cards. As I mentioned in my post of 7 March, I burned through two cards before eventually giving up and trying a new installation to USB disk. This seems to have fixed the problem …

plug instability

I’m still having a variety of problems with my sheevaplug. Not least of which is the fact that SDHC cards don’t seem to be the best choice of boot medium. I have had failures with two cards now and some searching of the various on-line fora suggests that I am not alone here. In particular, …

from slug to plug

image of sheevaplug

Well this took rather longer than expected. I intended to write about my latest toy much earlier than this, but several things got in the way – more of which later. About three or four weeks ago I bought myself a new sheevaplug. The plug has been on sale in the US for some time, …
