Alarm clocks in mobile phones

I would have chosen death instead

Except that I haven’t smashed the phone… yet.

Helena Amor photos

Filed under: UK — Tags: , — jesus @ 20:29

This is a simple blog post to introduce my friend Helena Amor, who’s trying to get into photography professionally. She started a few years ago with photography as a hobby and now she’s exploring it in a more commercial way, where she wants to dedicate her efforts and time to build a career around it. She’s mainly being taking portraits as she’s been doing for the last few months for actors and actresses, etc. but she is now moving into other areas like weddings, etc.

She lives in London and if you need some photos taken, give her a shot!

Social Engineering at Work

Filed under: ¿Pero qué coño?, Fun, Life — Tags: , — jesus @ 19:39

I’ve never had social engineering done at me, but recently there was this guy who phone me by directly calling MX Telecom‘s number. He said he was calling from DHL and that he had a package to be delivered for me. He wanted the name of two other people who would sign the delivery report in case I was not there. I complied and later a colleague told me that this is most likely a recruiter collecting names from the companies. Aha!

So, I had another call yesterday and this time I was quicker to react. The conversation went like this:

Hi, Could I speak to Jesús?

On the phone.

Hi, I’m a promoter who is organising an event at the O2 Arena for Playboy Magazine.

Playboy?

Yeah, the adult magazine, have you ever heard of it?

Barely, go on.

Well, they are organising this event for IT professionals and they wanted as many IT professionals to attend this event. I’ve got 6 tickets so if you could give me 5 names I’ll send them to you guys.

Sure, jot down please:

Juan Perez and Joseph Garcia, they are americans and have just arrived to the company.

Oh, sure. Is there any lady there who would like to attend?

To a playboy event? Yeah, I know of one: Ana Botieso, a nice Spanish girl.

is that all?

Yup, thanks a lot, I’m really looking forward to having those tickets.

No problems bye.

bye.

All of this while my mates at work were looking at me and giggling. Obviously the two first names were made up. The girl’s name stands for “An Erect Penis” in Spanish if you put it all together.

So you know, guys, if you ever receive such a suspicious call, you can be playful and have a bit of fun. You never know if you are going to get a call from one of these dicks.

Amdocs buys MX Telecom

Filed under: Life — Tags: , , , — jesus @ 09:27

So, the company I work for, wammux, has been bought by Amdocs, the super mega corporation that owns openmarket, in order to merge us with them. The deal has been $104 million in cash !!!

Don’t really know how that’s going to affect us. We shall see.

Apple Converted

Filed under: Computers, Life — Tags: , , — jesus @ 13:11

Over the last few months I’ve acquired a few items from Apple. Namely and Mac Book Pro 13″, an iPod Touch 2nd gen (which came with the Mac Book Pro and I’m reselling, probably) and an iPhone, with O2.

I’m quite pleased to be honest. It might be that I’m getting older but I’m lately not so apt to be continually fighting configuration issues and stuff with Linux (which I haven’t erased from my life. Use it at work, my servers and my desktop). Anyway, the Mac Book Pro was a no brainer, specially since it’s light, small and powerful (which makes it perfect for me to carry it around) and comes with Leopard (now upgraded to Snow Leopard) which is a very nice operating system (and I still love having good old unix underneath).

The iPhone was more of an issue in terms of decision making. I was considering getting an Android based handset, like the HTC Hero, myself, but after much though, I believe that it’s not ready and mature enough to go for it. So I opted for an iPhone. I’ll wait until next year and see how the market is and decide again (I can always sell my iPhone as there’s always a market for this). So we shall see.

Any suggestions to make the best out of all these Apple goodies?

Moving to London

Filed under: Life — jesus @ 02:54

Well, it was time to leave Brighton and move on to something different.

Boredom, lack of internet and sleep has been a constant over the last couple of months. Finally, I found a job in London and moved to it to, well, start something different/new.

Moving all my stuff from Brighton to London has been a bit of a pain in the ass. I had way too many things to move. Including a bike. I had to rent a car and move all my stuff in a heavy loaded car. Nice because it’s been an interesting experience to drive on the left side of the road (England!). It’s easier than it looks. Anyway, Although I’ll miss Brighton a bit, I was a bit tired of being in the same place living in a residence with eighteen-year-olds and the like. What I definitely will miss is the people. Well, some people more than others, but some special people. ¡Así es la vida!

And now, I have permanent internet connection, a house, a new flatmate (who is a good friend) and a new job that would definitely help me not to waste time thinking in girls (lack of), sysadmin (although I will get plenty of that [not the girls :P] at my new job) and how to pay the bills.

I’ll talk in a different post about my new employer and what kind of job they do.

Chord

Filed under: Internet, Programming, Sussex University — Tags: , — jesus @ 18:01

As part of another assignment for the Distributed System course at the University of Sussex we have been doing some research on Chord, a distributed hash lookup primitive, and, in the end, implement part of what is called a chord ring in java.

The idea behind Chord is a research paper in which a distributed protocol for adding nodes to the system, insert data into it, retreive it and drop from the system is described. The way in which nodes lookups and inserts are done is O(log n), so it’s quite efficient. Chord could be look as a layer over which p2p-like applications could be built. One example of this is CFS, the Cooperative File System, a distributed read-only file system.

What we had to do is, basically, implement a simple Ring protocol and a Chord protocol:

  • Ring protocol: Each node in the system has a pointer to the next one in the ring, so, for instance, if any node wants to do a lookup on some data, it would ask the next one in the ring. If such node does not have it, it would forward that question to the next node in the ring and so forth. This would be O(n)
  • Chord Protocol: In this version of the protocol, each node not only has a pointer to the next node in the ring, but it also has a pointer to a number of other nodes, not necessarily in a row, so when any node wants to do a lookup, depending on a hash function and the list of pointers to other nodes, it would forward the question to a closer node, where the information is more likely to be stored. This is the way we get a O(log n) algorithm. In fact, there is more than this going on, so I recommend you to have a look at the chord paper again if you are interested.

So, all we had to do is implement both protocols in java and run it in a
simulator, as implementing a working solution was too much for an university assignment due in two weeks.

What happens is that using the simulator and programming the whole thing is harder than it sounds, as the simulator itself is lacking some good documentation and have some bugs. In any case, doing it has been fun and interesting as well, as it has let me understand how a distributed system, such as a p2p system, works. So, I recommend anyone interested to have a look at how the protocol works (ie, by reading the Chord paper ;) )

Depeche Mode and Barcelona

Filed under: Life, Music — Tags: — jesus @ 17:30

Tomorrow I’m heading to Barcelona to see my first Depeche Mode concert of the Playing the Angel tour at Palau Sant Jordi sports arena, built for the 1992 olimpic games.

While I am not finding this last album exciting at all (maybe I am changing musical tastes), I am really excited to go to Barcelona, as it is always a city with a lot to offer. Also, I’m seeing some of my friends as they are comming from Seville to the concert, which is going to be lots of fun. And, they are bringing me some Spanish food I could take back to England (Yeah!!!) :-)
The venue is taking place in the Palau Sant Jordi, which is a very nice place to make gigs as it has pretty good acoustics and a capacity for almost 25000 people.

I’ll be arriving at 17:00 at Barcelona’s El Prat airport on Friday evening if there are no delays and will be back on Sunday evening. So, it’s going to be 48 interesting hours. Hope to get enough sleep.

I’ll be posting photos soon.

FON, google and Skype

Filed under: Internet, Sussex University — Tags: , , — jesus @ 23:34

So, they did it

Fon has just announced it would get 21.5 million dollars from Google, Skype, and Sequoia Capital. Something I already talked about a couple of days ago.

Amazing. Just waiting for comments right now!.

About FON

Filed under: Internet, Random, Sussex University — Tags: , — jesus @ 21:00

As part of my studies in my e-business
course at the University of Sussex, I have been asked to write a report of a company that is somehow involved with e-business (e-commerce, use of technology to become more profitable or efficient, etc.).

So, I have decided that I am going to do some research on FON, a company created by Martin Varsavsky who is famous for founding Jazztel and Ya.com, one of the biggest phone companies and ISP in Spain.

FON idea is to profit from creating a network of wireless users around the world, called the p2p of wifi.

My task is, first of all, writing a background briefing report about the company, and afterwards an investment recomendation based on my research and study of the subject.

I chose this company because I have a friend who is working there and because I think it is interesting to see if FON’s business model is profitable or not. By the way, I have no access to internal sources as Teo (hi Teo!!) is quite secretive about it (I think because of NDAs).
Anyway, I’ll post more about it in the near future, I guess. Stay tuned.
