I am deputy chairman of the UK Oracle User Group: Availability, Infrastructure and Management (AIM) SIG. We arrange several groups per year where we look to get speakers to present on all manner of subject in relation to the remit of the SIG: Exadata, RAC, Partitioning, Grid Control, Managing DBA’s, etc (for more info, check here). However, it can sometimes be difficult to get presenters, and close to impossible to get new presenters.
Now, most people are pretty scared to get up in front of their peers and present. It initially seems quite a daunting prospect. However, I was recently reading Dr Richard Feynman’s autobiography, which puts the fear of your first presentation into perspective:
When he was a graduate student at Princeton, Feynman was working as a research student and was encouraged by John Wheeler to give a talk on an electrodynamics theory they were working on, as “you need experience in giving talks”. Feynman found out later that especially invited to the talk were Henry Norris Russell, Professor Wolfgang Pauli, and Professor Albert Einstein. Three of the most preeminent scientists of their day (you might have heard of at least one of them).
So, if you think your talk is going to be difficult standing in front of a couple of contractors, 3 geeks from the local council, a couple of bankers and some bloke from a supermarket, it’s not. Well, not compared to being open to critique by Pauli and Einstein! Nobody is going to be critical of your talk, only supportive. Nobody expects a presenter to have all of the answers. Many of us have witnessed the consummate presenter Jonathan Lewis writing impossible SQL on a flip chart, much to his chagrin. So if Jonathan can make an amusing mistake, I don’t think we’re overly worried about anybody else making one either.
As for Feynman, his only regret about the seminar as that he can’t remember exactly what Prof. Pauli has said when he raised a question, as he thinks it might have been the answer to making a quantum version of his electrodynamic theory.
So, if you DO present, and I would really encourage you to present, listen carefully to any questions asked by the audience. They just might give you the answer you are looking for.
For the record and to stop frivolous posts, Martin, I DO present occasionally. Just not as much as perhaps I should.
Well, there’s a lot been said about bankers in the last few years, much of it negative and with good reason. Tony Robinson asked if they were human in an excellent rant on Question Time. Manipulating the LIBOR is pretty egregious. It undermines the basis of truth behind our (formerly) well-regarded banks. It shows them to be self-interested liars and cheats.
Many of the huge numbers of people who work for banks are just doing their job, ticking along, feeding their families, not being evil. I have worked as a consultant inside many banks, and have also worked directly for one or two. The staff in banks are like workers everywhere; some good, some bad, some incompetent and some dazzling in their genius. Like all large companies.
At present, Barclays has covered itself in shame and I suspect that it’s merely the first name on the guilty sheet. However, I’m a Barclays customer. I have a couple of accounts with them. I use the current account daily.
I don’t think I can continue to be a customer of a bank whose behaviour is so reprehensible.
It would seem that the law cannot prosecute the offending parties within the bank, so I feel my only recourse is to leave the bank. I don’t need Barclays. I’m going to move somewhere more ethical, so I need to look at the company as well as the interest rates. I already have other current accounts that I can use, which will happen in the short term until I strike the right balance between ethics and savings.
If EVERYBODY did that, Barclays would no longer exist to be unethical.That would make a lot of people unemployed, including several friends and family members… but…
Ask yourself this; why do you bank with your current bank? Apparently, you are more likely to get divorced than change bank account – that’s why they pay good interest to kids. Get ‘em young and get ‘em hooked.
It’s SO easy to change your current account it’s amazing that more people don’t do it. Plenty of banks even pay you to move to them! You open an account with your new bank and ask them to move your account. They do it all – letter to your employer, direct debits, standing orders, everything. And they usually give you a (temporary) large overdraft to ensure you have no payment problems.
Bank with your conscience
Increasing numbers of Yahoo mail passwords appear to have been compromised; I don’t use Yahoo [although in a historically stupid move, I have multiple email addresses from multiple providers including hotmail, gmail, my ISP and my own domain ]. Anyway, I have been getting an increasing number of spam emails from friends and acquaintances with Yahoo accounts. Not from any other source. I have been multiply spammed from multiple yahoo accounts this year, but from no other provider. The conclusion I draw from this is that either Yahoo has had its password file compromised and the spammers are slowly working their way through it, or it has a significant hole in its security, or there is a focussed piece of malware out there harvesting Yahoo passwords.
Either way, I would strongly recommend that anybody who uses a Yahoo email go and change their password, make it computer-complex (i.e. long), write it on a Post-it and stick it next to your desk (at home – not in the office where everyone can read it)
WHAT! I hear you cry. Why do THAT! You’re mad! Well, no. Brute force attacks are rare, and they will generally use standard dictionary words. I hate to tell you, but hackers know you replace E with 3, A with 4 and L with 1. So your password of AFR1C4 it as much a dictionary word as AFRICA to a computer. [ If you want a really hard-to-crack, easy-to-remember password, I suggest you refer to this XKCD cartoon http://xkcd.com/936 ]
The likelihood is that your password will be compromised by malware and not brute force attacks, in which case it doesn’t matter how complex it is. The chance it will be compromised by a burglar looking in your desk drawer is very low indeed (although people with teenage children need to be a bit more cautious.)
And change your passwords occasionally – at least once a year. How many of you out there have 2 or 3 different passwords that they use everywhere? A (seemingly) complex one for your bank account and “password” for your forum accounts? And you have NEVER changed them as it would mean changing 200 accounts and it’s too much like hard work? Thought so. One day you will be pwned by the hackers.
The UK Oracle User Group has put out it’s call for papers, and the deadline is rapidly approaching.
Have you registered as a speaker and sent in a abstract yet? NO? Don’t you know how great an opportunity it is for you. Discuss your ideas with your peers. Network. Instruct and inform. Help other avoid the pitfalls which dogged your project. All by telling everyone about it. We will love you for it at the user group. And you will love the feedback you get. Anyone can speak, everyone has a good story to tell.
You need to register by THIS FRIDAY, 1ST JUNE!!!
Go on. Try it. http://techandebs.ukoug.org/default.asp?p=9306 – you might surprise yourself.
