The Power of Telnet

A client had a problem with “stuck” email in there inbox, we’re not exactly sure what caused this but there were about 60+ emails waiting in there email box all of about 3MB and all the exact same and they just never downloaded. (Mail is downloaded via Outlook using a pop3 account)

This has been a rather common?occurrence?lately with email accounts hosted in the US. Our normal method of fixing this is log in via the ISP’s webmail front end, go through the mail and delete any messages that are “junk”. Unfortunately that did not work, the minute the Inbox was opened the page would sit trying to download and then finally timeout.

It was time to use some knowledge that I acquired in my “younger days” when I hung around the darker parts of the web… you can access a POP email account using Telnet, the big advantage of using telnet is that you never download the message, in fact you don’t even have to see the message to be able to delete it. The downside is that telnet is not the easiest tool to use to read your email, you basically have to stick in all the raw POP commands from the specification in order to login and access your email account and manipulate the emails.

I don’t remember all the commands for POP servers but the basics on this page were enough for me to delete the offending emails and fix the problem.

While fun and not particularly dangerous, this is not something for your typical “user” as it involves command lines, typing often blindly at prompts and careful typing to ensure you make no mistakes as back space often doesn’t work.

World Cup fever!

This morning I was awoken by the sound of vuvuzela’s and car horns… at 6am as Cape Town got into the spirit of the soccer world cup.

The FIFA soccer world cup officially starts today, I’m can’t predict who will win the opening game between Mexico and Bafana Bafana (South Africa) but one thing I’m sure of is all we’ll hear is the sound of Vuvuzela’s. Everyone is getting into the spirit of the World Cup, almost every car on the streets as some kind of flag on and all the stores, offices etc have flags, soccer balls and vuvu’s… its incredible.

World Cup Girls

The girls in the office came into work today wearing there soccer gear, thats my wife (Claire) on the left in Blue and Chantelle on the right.

The uncapped ADSL experiment

I’ve decided to give uncapped ADSL a try for my home connection, I’m not sure yet if it’ll work or if it’ll save me any money or bring on more frustrations… After asking around amongst my friends I’ve decided to give Afrihost’s Uncapped 384kbs connection a go and see how things go.

Unfortunately Web Africa (my favourite ISP) doesn’t offer anything like this in the same price range.

I’ve only just signed up for it, so I can’t really give an accurate review of it… but the wife and I will give it a good test over the coming weeks and I’ll report back here and let you know how well it works.

419 Scam

Early this morning I received an SMS that said the following (copied from the sms):

Congratulation !!! You won R1,000,000,00 (one Million Rands), your number was selected among the lucky winners of Chevron World Wide international South Africa lottory bonanza Ticket NO: 0404 Batch No:7777 contact our fiduciary claim agent on this number (0763005305) to claim your prize, or email: chevronpaymentdept@gmail.com. Contact person MR MIKE NKOSI. T&C Apply.

The sms came from the following number +27727262858

I hope that you can all see that its a scam message, I can’t believe the Chevron or any company involved with them would make so many spelling and grammar mistakes and why would they use a @gmail.com address? and why is the contact number a cell phone number and not some kind of call center number?

But just in case it wasn’t a scam, I thought I would send them a quick email… (I had entered a few competitions at the local Caltex service station and Caltex is owned by Chevron.)

What follows below is a copy and paste of the email discussion I had with the “chevronpaymentdept@gmail.com”

Mini Mill & Lathes

Sieg X2 Mini Mill

I’ve been looking for this and can’t find any info online for companies selling mini mills or lathes in South Africa, except oddly enough my posts on this blog. I can find plenty of the big machines but they’re too big and expensive and overkill for what I’m looking for. I’ve noticed that a few of the hits for this site have come from people searching for CNC machines, mini mills and lathes so I guessed that perhaps by writing a post about them and what I’m looking for someone might be able to point me in the direction of a local supplier.

Firstly I guess I should point out that this is a pipe dream, I won’t have the space to set one up till I move into our new place (in a few months time), I’m not sure if I’ll have the money (I now have a house bond to pay) and I’m not sure if I would get approval from the wife to buy an extremely expensive, noisy machine that allows me to turn metals, plastic and other stuff into shavings while probably injuring my self. But those are all minor obstacles and they don’t prevent me from dreaming of one day having a workshop filled with awesome machines.

I’m looking for what is often called a “mini mill” essentially its a small version of the big mills used to machine metal into all kinds of wonderful shapes. My ideal machine would be a table top machine that allowed me to machine metals such as?aluminium, brass, certain types of plastics etc. It’s ok if it couldn’t machine the really hard metals or anything big, I’m not going to be using it to make car engines or parts for the space shuttle replacement but rather it will be used to make small parts for things like hobby engines and parts, parts for things like paint ball or air soft guns, little robotics projects other similar things. While precision is always important its unlikely I’ll need anything machined to extreme tolerances and I’m unlikely to make anything that will be spinning at high rpm’s or anything.

I also would love a small lathe that can turn metals, similar to the mill this would also be used to make small parts things like screw threads, gears etc (I know these kinds of things are hard to do, but I would like to at least give it a try). Again this is for garage/hobby use, I’m not starting up a business machining stuff for people I just want to be able to make those weirdly shaped metal parts that my various crazy project may require.

I’m not looking for a CNC machine as they’re alot easier to build your self and would be a “project” that I could use the mill and lathe for.

While this is all a pipe dream at the moment, I would love to know where in South Africa I could buy these kinds of things and how much they would cost. That way I can determine how much of a “pipe dream” this would really be… if anyone reading this knows where in South Africa I can find that info please leave a comment.

On Demand Book Printer

I found this via MakeZine but I think its one of the most awesome things I’ve ever seen. It’s a standard Laser printer and what looks like a Canon Inkjet printer combined with a fancy bit of mechanics to hold, fold and cut paper. The complete system can print a book, a real softcover book in a few minutes and will handle up to about 850 pages.

It’s a pity the system is patented because I would love to build and sell these but thats not going to happen. What amazes me is if this was combined with some of the opensource textbook projects and give it to schools or perhaps put in a central place in a town you could print textbooks for kids on demand, printing only those portions that were required for the class they were taking, whats even cooler is you could perhaps combine textbooks into one book making it easier to carry.

The system would also lower the cost of the book as publishers no longer need to worry about doing large runs of books, storing, shipping or even having an order handling department.
