BT Icing

The next episode in this saga is that some contractors turned up, dug up the street and installed a new well and pipe to my wall to take a new line! The icing on the cake after the cake had been mixed, baked and eaten!

What will happen next?!

Happy to report performance is still solid.


Experience with switch to BT!

You have to have some sympathy for the people who work in the BT complaints department in India. You get to listen to annoyed people like me complain all day long so not a pleasant jobs and a thick skin required.

So I take my hat off to them whilst being annoyed at the overall service.

I finally made the decision to switch from Virgin after the latest increase to £35/pcm when my “special deal” ran out plus the fact that there is a terrible dip in bandwidth in the evening – I’ve been collecting stats for months. The other attractive offer from BT was a new line included when you ordered BT Infinity which gave me the opportunity to move the master socket to the middle of the house – a much better place for Wifi than the corner of the lounge.

So, it starts well when an support person calls and says she will be in charge of everything (I don’t think I heard from her again). An engineer visits and checks that the current service cannot support another line for broadband so we agree the only option is to lay a new cable from the street to the corner of the house – the cable from there to a new master socket is installed. Now I am waiting for contractors to arrive and dig up the drive for the new cable and things start to go wrong – a succession of engineers arrive to contradict the first engineer and by the third visit (about three weeks later) convince me that they would rather disconnect the current land-line and use it for the broadband (and new number). To be fair, I was going to disconnect the original line when the broadband was up and running so the expense and hassle of digging up the drive was not strictly necessary.

However, it did mean that my home number of 15 years was cut off and I had to be organised to get an order to move that number to the new line. Luckily that happened ok so I got my original number back.

So now BT Infinity is up and running and it’s working pretty well, reliable 70-80Mbps download and 16Mbps upload (much better than Virgin). A hassle to re-number all the static devices and some undesirable quirks of the smart hub e.g. not being able to turn off SID broadcast.

The next problem appears – cannot log in to BT mail. I configured an address which the website told me would be available to use in 30 minutes but something went wrong. BT mail disappeared from “My Extras” and could not log in. A succession of 2nd line support people called me and some even called me after 22:30 when I was falling asleep which really annoyed me. I registered my displeasure at the complaints site so someone else started calling me. The lack of mail was particularly irksome as to be able to send mail, MacMail has to be configured with an SMTP server and I could not connect to a BT SMTP server without the email account. I had to keep the Virgin service running to send mail.

The mail issue was eventually fixed at the end of October by the back office after ordering at the end of August. BT offered me £5 by way of goodwill, which just annoyed me even more. Mail is “free” you see so not worth anything in BT’s world.

Having done all that I called Virgin to cancel my service and close my account. Now I have customer services calling me to persuade me to stay. They offer me 150Mbps and £15/pcm! Big difference from £35! But too late and that won’t solve the performance problem.

Now it’s all configured and running, it seems good – but time will tell. Having the competition / choice is nice.


Epson trouble

Well the good news is that I got BT Infinity working – there was a bit of a mix up with BT about the installation of a second line – they realised they had to dig up the drive which they seriously didn’t want to do so disconnected my old line and used it for the new number. I was ok with that because I was going to disconnect the old line anyway but now it turns out I might not be able to move the old number to the new line and I will be seriously annoyed if I lose my home number of 15 years.

With the line up, configuring everything was quick and easy apart from – you guessed it – the Epson printer. When I first installed the printer, I had a serious moan at them about how their DNS didn’t work and they blamed the ISP after which I never got a response. Now I have spent two hours trying to reconfigure it from the old network to the new one and I can’t do it – not the way I want anyway with a static I/P address. I had to factory reset it to be able to connect the the Wifi at all. USB connection does not work.

As a printer the ET-2550 is ok but the interface and software is dis-functional. Don’t buy one unless you really, really need the ecotank feature. The other advertised features don’t work either and the entire configuration experience is not worth the hassle.


Is that a word? Well, it’s what this blog has turned into – a diary of family IT woes. However, some good news – I finally place an order BT Infinity! Virgin put their price up by £10 / month, or to be more precise my “special” discount ran out after I threatened to leave the last time.

£35 / month for just a broadband service which dips every evening and particularly at the weekend is too much. Let’s see what BT is like and at the same time I can get them to put the master socket in a location near the end of all my wired ethernet connectors.

In other news, we bought a new colour printer, an Epson Ecotank 2550 which so far has been fine. Supposedly has a 2 year supply of ink, and re-fills are cheap. One fly in the ink is that it fails to register with Epson Connect – got a call logged about that but it’s not a big problem at the moment.


Holiday Programming

I’ve always enjoyed the combined creative and logical process of programming. But like so many other things, it’s not a priority over other, more necessary daily tasks.

So a summer holiday, with very little else to do is an ideal opportunity to create a tool I had an idea for last year. In my current role, I need to take into consideration operational hours of services (applications) and maintenance windows of the infrastructure on which they run. The sounds relatively easy but is complicated by the hours being specified in multiple timezones – as the users are typically global – and the maintenance window being in yet another timezone.

To determine if a global application will fit in a given maintenance window involves converting all the times to a single zone (not forgetting daylight savings) and interpreting the table to see if there is any overlap. This is time consuming and error prone.

So much better to display the data graphically, on a clock face. One segment can represent the operational hours, another segment the maintenance window and if the two overlap, then there is an issue, which you can see in a blink.

I was unable to find an existing tool to do this so I have written it (using C, Cairo graphics on Centos).

At the moment, the program prompts for a single range of hours, but an obvious enhancement is to read these from a file – and perform the necessary timezone conversion. However, the output will look the same and a couple of examples are shown below.

Example 1

Example 1



Example 2

Example 2

Example 1 shows an application which has operational hours from 15:00 to 20:00 and a supporting system maintenance window of 23:00 to 02:00.

Example 2 shows a slightly more realistic application which runs from 07:00 until 05:00 but relies on a database which is unavailable from 04:00 to 06:00.  The overlap shows the problem straight away.

It works for me, but whether it will survive in the wild is another question! Do doubt there will be feedback which will lead to enhancements, although maybe I’d need another holiday to make them.

BTW, the trickiest part of this was positioning the text around the outside of the clock face. The text reference point has to be moved as the angle (and characters) change. This still needs some tweaking and perhaps I need to look carefully at a variety of clock faces.

AWS Summit London 2016

I went to the AWS Summit at Excel today, along with a few other Solutions Architects. The talks from companies (of all sizes) who have used AWS were a lot more interesting than Werner this year. The session on Supercomputing on Demand was the best for me.

Overall, the sheer size (5,000 people) meant it lacked the atmosphere of smaller event, such as the Blueprism partner day I attended recently. It was more like IT Expo with the partners stands trying to sell their solutions.

There’s certainly some new features I need to brush up on though.

Quantum Computing

I’m really just writing a post so I don’t forget how to do it. However, I have been getting interested in quantum computing (how does that work???) and consequently reading a beginners book on quantum theory, which isn’t much help to be honest.

So far, I think it has something to do with the principle of least action, reversible logic and goodness knows what else.

If I get work out anything useful, I will be sure to write it down. Don’t hold your breath though.

All quiet

All quiet on the domestic computing front at the moment. Everything pretty stable (I don’t use the Mac any more). Bought a Kingston 120GB SSD for about £35 – incredible price. I think I paid a few hundred for a 30M hard drive for my Amiga!

Next investment might be a colour printer, thinking of the Epson Ecotank range.


Centos 7 pain

I suppose it had to happen. I did a major update of Centos 7 last week which downloaded megabytes of package updates. Since then, software updater disappeared, software disappeared, sound in Firefox stops after 12s.

For the record I am in 7.2.1511 and Gnome 3.14. I don’t know what they were before.  After some searching I found a package to put back the gui for software updates. More searching and I yum installed gnome-software. Re-downloaded Firefox which says it is 44.0 but still complains it is out of date.

I mean, come on. How hard can it be to actually maintain a working home system???? After I ditched Apple, Centos was doing so well, meeting all my needs and now it’s broken or at best will take hours of fixing. What a crock of shit.
