Since 8.0.16, MySQL Server supports a --validate-config option that enables the startup configuration to be checked for problems without running the server in normal operational mode.
--validate-config can be used any time, but is particularly useful after an upgrade, to check whether any options previously used with the older server are considered by the upgraded server to be deprecated or obsolete.

The post Check the MySQL server startup configuration first appeared on dasini.net - Diary of a MySQL expert.

Read the original article at Consulting essentials: Getting the business

Over the years, a lot of people have approached me asking how to become a tech consultant. What do I need to do to get started? How can I take my first step?

I also hear from managers and CEOs that have asked how I got my start, and how I keep the business running. What lessons from consulting can be applied to startups and small businesses? Having worked independently for many years I’ve built up my own cache of strategies and methods which I hope can be helpful to anyone looking to strike it out on their own.

This is the first of a series of three articles on consulting essentials. Part two covers …

Read the original article at The Problem with Startup Bootcamps

Scanning Crains NY Business recently, I saw an article on 'starting up' in 54 hours.  It's the brainchild of Marc Nager, Clint Nelsen and Franck Nouyrigat called Startup Weekend. Startup bootcamps seem to be the current extra-curricular activity of choice these days. Wharton is also getting in on it with their Innovation Tournament. Then there is the …

Read the original article at Book Review – The Lean Startup by Eric Ries

What do you do after founding not one, but two companies and watching them fail miserably all by the time you were barely out of college?

Move to the Valley, make shrewd investments in other startups and become insanely rich like Sean Parker? A Bit lofty perhaps. How about try, try again and succeed. Then reinvent yourself as a guru dishing out startup wisdom through your blog and publishing a book that ends up the top of the New York Times Bestseller's list. That's essentially what Eric Ries, author of The Lean Startup did.

True entrepreneurs fail many times before they succeed and continuously find opportunities to reinvent …

I swear, my intention was to go for a break. A year taking pictures, sharing them over the web, writing texts, running, kayaking, just being social. Honestly, ask my family and friends!

But this was not to be, in spite of what I said when I announced my resignation just days ago. Instead, I am joining SkySQL Ab, the startup that aims to become a new centre for the MySQL universe. My role will span Marketing and Engineering, and is like the title “EVP Products” inspired by Zack Urlocker’s role at MySQL AB.

I would have preferred the company to have been called KajSQL, but have come to terms with the company having an extra phonetic “s” in the beginning. Quite a while ago, having eaten my favourite fish “ …

I attended a panel session at the South by Southwest Interactive conference recently on the topic of high-tech startups in Europe.  The panel included Marten Mickos (former CEO of MySQL, now at Eucalyptus), Resham Sohoni (CEO of Seedcamp), Peter Robinett (Bubble Foundry) and Felix Petersen (Nokia).  It was interesting to learn about some of the initiatives, like Seedcamp, which are investing in and promoting startup companies like Erply, and Codility coming out of eastern europe. These companies are small, but they have big ambition and are leveraging open source and cloud infrastructures to keep their costs low.

Debian Linux (the underlying foundation of Ubuntu) manages the startup/shutdown of MySQL quite differently from the ways I am used to. I am a long-time user of both the MySQL binary provided by Red Hat/SuSE (along with Fedora and clones like CentOS and Oracle Enterprise Linux) and the official binary from mysql.com. After the successful restore of a cold backup, I started mysqld using the Debian provided init script. The script said that mysqld failed to start up, but in reality it did start up. Similarly, stopping mysqld fails.

The output below demonstrates the outputs and the behavior seen on a Ubuntu 8.04 LTS Server:

root:~# ps -ef | grep mysqld
root     20165 19926  0 15:12 pts/4    00:00:00 grep mysqld
root:~# /etc/init.d/mysql start
 * Starting MySQL database server mysqld                                            [fail]
root:~# ps -ef | grep …

Few days ago we were chatting in our corporate Campfire room and one of the guys asked me what do I think about Rails developers hiring process, what questions I’d ask a candidate, etc… This question started really long and interesting discussion and I’d like to share my thoughts on this question in this post.

So, first of all I would like to explain what kind of interviews I really hate Ever since I was thinking of myself as of a developer (many years ago) and was going to “software developer position” interviews I really hated questions like “What is the name and possible values of the third parameter of the function some_freakin_weird_func() from some_weird.h” or “How to declare a virtual destructor and when it could be useful?”… All my life I had pretty practical thinking and never bothered to learn APIs or some really deep language concepts that are useful in 1% of …

Daniel (aka Mr. Messina of Malaysia) is organising a bunch of events, and since they’re on weekends, I’m going to gladly participate, without seeking approval from the overlords.

First up is Startup Camp KL, on 22-23 November 2008, in MidValley. On Sunday, I’m going to lead a session titled “Using Free Software to bootstrap your startup”. Check out the agenda. It should be fun, especially in today’s market to ensure there are no software licensing costs, especially if you’re a startup.

Then there’s BarCampJB, 6-7 December 2008, in Johor Bahru. I haven’t been there in…. ages :) I’ll be talking about “MySQL Best Practices for Developers”, where we’ll go …

Update: Sun has expanded its Cloud Computing portfolio with the recent acquisition of Qlayer, a cloud computing company that automates the deployment and management of both public and private clouds.  The Q-layer organization, based in Belgium, is now part of Sun's Cloud Computing business unit which develops and integrates cloud computing technologies, architectures and services.

Cloud computing is about managing petascale data. Sun's server and storage systems can radically improve the data-intensive computing emerging in the cloud. Some clouds are closed platforms that lock you in. Sun's open source philosophy and Java principles form the core of a strategy that provides interoperability for large-scale computing resources. Sun's virtualization solutions for advanced …
