In an ideal world, potential customers would read this blog then decide that they want to do business with me.
In the real world many of my customers haven’t heard of a blog, and are quite happy that way thank you very much.
Given that a lot of ‘selling’ to these customers is on a personal level, the fallback is to use the traditional common or garden CV. Which gives rise to the following problems :
- Too Long or Too Short? : How do you get 13 years experience into a document without it looking like a version of ‘war and peace’?
- The curse of the technical buzzword : You need to include the technical buzzwords (Oracle, Java, Agile etc) to show you can do the job (a lot of people just do a 1st scan for words like this). But, put too many in, and you just end up looking silly.
- People or Technical skills: Apparently you can have great technical skills , or great people skills , but not both. How do you stop yourself getting pigeonholed? What about non-traditional experience (e.g. blogging, writting, speaking, training?)
- Customer confidentiality: A lot of the stuff we do is internal to clients. But potential clients need to know what you’ve done to judge your work. Where’s the balance?
You can judge how successful I’ve been here: Paul Browne’s CV online [pdf].
Yes, I’m slightly more available than normal in the coming months. Yes, I’ll consider proposals slightly outside ‘normal’ contracts, if the projects and upside are interesting. And yes , I may just take some time off that I’ve been promising myself (but I’ve said that one before). Email me at PaulB@firstpartners.net.
Note to recruitment agencies: I’m very happy consulting through FirstPartners. No, I don’t want a permanent job. No, Cork is nowhere near Dublin , but I will consider Belfast. No, I don’t believe that you’re in for anything other than the money – that’s ok , you probably have a family to feed; but let’s not waste time pretending otherwise.
Just discovered this RSS Feed giving a summary of all the bloggers employed by Oracle.
If you prefer to pick and choose your Oracle bloggers, the full list as a HTML or OPML page is available here.
You may remember we did the Enterprise Java presentation at DCU back in October for the wireless skillnet in Ireland. We’re doing a follow up presentation, this time in Central Dublin, on the 22nd January. The audience is mainly business people with some sort of interest or connection with technology.
Irish Dev has more details.
The topics covered include:
- What Problem are we trying to solve?
- Enterprise Java Architecture Overview.
- Benefits to the Enterprise.
- Alternatives (.Net , PHP , Oracle , Lightweight Java Frameworks , scripting)
- Vendors (IBM, Oracle, Sun , Bea , JBoss and SAP)
- Market Trends – Resource availability (can we get the people to do this?)
- Enterprise Web 2.0 and Service Orientated Aritecture (SOA).
- Integrating with other Systems ( Legacy Systems, Oracle etc)
- Enterprise Java Beans 3 (EJB3)
- Middleware (MOM, Rule Engines, Workflow)
- Security – Application and Server Level including Java Access & Authorization Service (JAAS).
- Frameworks (Struts , JSF, ADF, DWR, Spring, Hibernate)
- .Net interoperability
- What’s next for Enterprise Java?
Doing a lot of database work for a client right now so now it’s a good time to recap on where you can store your information. This might be basic stuff , but it’s essential basic stuff.
- So you have your information, and now you want to stick it on the web. MySql is the database of choice. Free, lightweight and with excellent tool support (e.g. phpMyAdmin), MySql is what powers this website. If you know what you’re doing (e.g. Google or Amazon) it will scale very very well.
- For most people , the next step up is to a serious Enterprise database. Oracle, MS Sql-Server and it’s cousin Sybase are the main contenders in this area. DB2 from IBM is a distant fourth place while Sybase is strong in financial institutions. While MySql is catching up in features, most companies chose one of the main three because of their track record, a long list of people and vendors that support them, and because of ‘lock-in’. Once you choose a database it’s very hard to change.
So there you have it. Don’t let me see you trying to run a company on Excel or Access again. Or at least, don’t complain to me when it falls over!
If you remember Applets, then you are so 1990’s man. Right back before the dot-com boom , everybody was putting these Java programs in their web pages to do things simple things like display a financial chart (guilty as charged , my ‘lud). Oracle still uses them in some versions of it’s applications as a half-way house between it’s older desktop applications and a completely web only solution.
Fast forward to 2006 and these ‘heavy’ applets have been replaced by light web pages using Ajax and Flash, which don’t require a user download to run. Pretty much anything a Java Applet can do can be done in Ajax (if you have enough time and patience). Ajax developers have been pretty inventive in using Flash to solve problems (e.g. allowing web pages to store information on your local PC), so it may only be a matter of time before this gets picked up.
Jan of Trampoline Systems explains in more detail.
Now that the dust is beginning to settle on Sun’s Decision to open source Java , what does it actually mean for you? That’s you as in a Business user, you as in a Java Developer , and you as a member of the wider IT Community?
- In the short run (i.e. next 6 months), once the buzz dies down , not much. Remember that it took several years after the Netscape code was open source for Firefox to emerge and change the dynamic of the browser market.
- In the medium term (between 6 and 24 months) expect some interesting packagings of Java to emerge, similar to the way the various Linux Distros work today. Consider these ‘green shoots’ or prototypes with interesting ideas. A ‘small footprint’ version of Java targeted at Applet developers seems to be one popular opinion of what might emerge. However, unless you are ‘bleeding edge’ or in a niche area the chances are you won’t notice them at this stage.
It is in the longer term (2 years plus) that open source java really makes it’s mark. Some predictions that you can quote back to me later:
– In the same way as JBoss and Geronimo have commoditised the app server market programming languages and runtimes will become a commodity. Expect the .Net platform to be opened (not just standardized) in some limited form.
– Java will become more like .Net with multiple languages running in the standard JVM. We have JRuby and Groovy. It wouldn’t be too hard to add C# to this list. Visual Basic in the JVM (the Sun Semplice Project) is already on it’s way.
– Oracle , IBM , SAP and others already committed to the Java market will become focussed on Java as an even bigger part of the core strategy. Just like the app server market, each will seek to differentiate themselves, perhaps by Service (IBM), by a core database (Oracle) or by leading a niche (SAP). Expect tension between the desire to differentiate (and fragment) and the GPL which seeks to ‘bind them all’.
– Apache Harmony , a clean room implementation of Java will continue to gain momentum. It will get picked up by a major vendor in a similar manner to Apple using BSD code.
– Microsoft .Net will end up in a ‘death march’ with Java trying to gain a lead in a feature set. Open source is very good a mimicing existing products (as it makes an easy spec for dispersed developers to write on – just look at Open Office), so (unless software patents get thrown into the mix), it’s hard to see .Net getting a fundamental and lasting edge over the Java Ecosystem.
Update: I’m not saying that .Net is going to go away (nor should it), just that both it and Java are going to be around for a long time to come. Joe and John also have more commentary.
Back in the dark days when World War III threatened us with imminent nuclear oblivion, we were told that cockroaches and other insects were the highest form of life that would survive. I’ve recently come to the conclusion that SQL programs, like cockroaches, will surive anything that the IT world can throw at them.
SQL is a way of getting useful information from databases ,like ‘get me all Bank Customers with an account balances greater than 10,000 Euro’. It’s been around since the stone age and it is strongly suspected that the ancient Egyptians were familar with it’s earlier forms. Given that at least part of most systems talk to a database, it is probably the most widely used programming language in the world. It’s the most widely used because it’s the most useful : do one thing and do one thing well.
However, you get into trouble when you use SQL in ways nature never intended. Once you step beyond the ‘get me this’ or ‘update that’ you’re in trouble. Like a 12m high cockroach from a 1950’s Horror Movie, your code is out of control. Even Oracle are migrating to a Java stack to implement business logic outside of the core database engine.
By way of apology to any Oracle or SQL-Server progammers offended by this post, I’ll share the news that I’m my way to getting Oracle certified. It’s Oracle Exam SQL-007 [pdf] and if you understand that , you’ll know that while it’s not bad for a Java person, guys like Donal Daly , Mark Rittman and Scott Spendolini aren’t under threat from me just yet.
