 The image says it all - it's here! Ubuntu 10.04 LTS has finally arrived, slightly late due to an issue with multi-boot, but I'm even more late because I haven't had time to play with it yet.
LTS will bring a breath of fresh air for companies who count on stability, the LTS, or Long Term Support, offers a new Ubuntu experience with the guarantee that we won't have to redo any particular development or reinstallation for another 2 years. It replaces Ubuntu 8.04 LTS. For example, ST Ericsson relies heavily on Ubuntu 8.04 LTS, and there are a lot of internal developments here that depend heavily on 8.04. There is no way that they could re-develop every time a new version comes out, with new libraries, new versions, some packets being removed and new programs being added. Now that 10.04 is here for 2 years, they are considering a massive switch. 10.04 is being freshly reinstalled on my netbook, since the entire system is encrypted, I wanted to do a fresh install. The Atom box at home did an upgrade straight from 9.10 to 10.04, and apart from the fact that Canonical's servers were heavily hit right after release, everything went extremely well. I hope to have a few howto's on my site within a few days, but in the mean time, I'm having fun!

When you walk around with a Tux on your keychain, chances are that when you are invited out (if ever that happens), people will ask the question - "What's the deal with Linux?". Why Linux? Why did you choose that system? What's wrong with Windows? What's different? Why should we use it? Recurring questions... I've had years to think about the "right" answer, and I've come to the conclusion that there isn't one. My personal answer is this: Dedication, and Choice. I have the dedication, and the choice, to use Linux. I stopped using Windows "full-time" the same day that Windows 95 came out. That doesn't mean that I don't use it from time to time; helping friends with their computer, developing applications for Win platforms, work computers, or just surfing the web whilst at a friend's house. It was my main work platform for years when I worked for Packard Bell NEC. I was even given the role as a beta-tester for Windows XP. So you can imagine the amount of fiddling I did on the systems. My role was to test applications and games coming from the 98/2k realm, and see how they worked with XP, then send of some results. Constant contact with Microsoft, and the editors. Every time I send an email, I really didn't know who was going to get the email, even if someone got it. A while later, I got a reply in my email telling me that thanks, my message was received, and that someone will look into it. The email was sent from customer dot support at whoever, and I didn't even know if it was sent from a program, or from a user playing with Ctrl-C, Ctrl-V. It lacked personality. When reporting a bug for a Linux program, it doesn't happen that way. You don't send a blind email to a company, you log onto a forum, and explain what happened. Someone, a human, answers. So long as your request is structured and relevant, answers will be coming soon. You can actually check the progression, watching people try to reproduce your bug, the different results, hypotheses, and eventual corrective action. From time to time, someone will answer saying that he hasn't got a clue, and this is actually important. It shows that the people here are humans; they have their strong points and their weak points, they are either asking for help, or giving it. They have names, family names, Christian names or sometimes just pseudonyms, but the have personality. Christian is an accountant, Stephanie is a graphist, Alex is a manager, this isn't necessarily their job, but they are spending time helping, because they feel that it is right. I also feel that it is right to hep that way, and yes, I know that some people will take full advantage of that and not give anything back, but hey, that's the game. Some will ask more than they give, others will give more than they ask, and the rewards can be extremely gratifying. A simple "Thankyou!" on a forum is a serious boost to morale. This is what the Open Source community is about. For some it is their job, for others it is a vocation, but an entire community is there to help eachother out. Armel Kermorvant, former boss and now OEM Vice President at Mandriva, has this to say about Open Source: "They are very interesting technologies because open source works as a community. All issues or questions are very important for everybody." That's about as short as it gets, but it is spot on. So that's dedication, but my dedication to helping others, and the dedication of the Open Source community. But what about choice? Choice is the key word to Linux. You don't have to use it, you have the choice to use it. But which one? Ubuntu? Mandriva? Redhat? Fedora? Debian? The list goes on and on, but in the end, it comes down to choice. Each distribution has it's own philosophy, and it is up to you to decide which one you prefer. It isn't that easy with Windows. Today, the choice is either XP or Vista, and even then, some don't have the choice, depending on their hardware or applications. Sure, you can customize it, but to what extent? You can change the wallpaper, the colours, some of the fancy animations, the icons... Practically everything. But not quite everything. The file manager is the same, and you can't change that. Back in the days of Windows 3.1, you could, but those days are long and gone. With Linux, you can. Choose your distribution. I chose Ubuntu. Choose your window manager. I chose Gnome. I could have had KDE, XFCE, AfterStep, Enlightenment... Once again, the list goes on. In the wonderful world of Linux, when you have something to do, you have the choice about what tools to use, and making a choice will not limit you to what you can do next; everything plays well with everything else. Install KDE, but you can still use that Gnome application. Install XFCE, and you can still use the KDE applet to monitor your system battery. Linux will even give you the choice to install other operating systems, and let you use them. Linux will happily give you the choice to start Windows or Linux, but Windows doesn't ask any questions, and will automatically start Windows from there on. Don't get me wrong; choice is good, but it can also be bad. My shiny iPhone is the perfect example. The iPhone is sexy tool, but in order to just start it up, I had to have either Windows or MacOS. It won't start otherwise. It has to be registered through iTunes. All the applications I use have to go through iTunes. My music, videos and photos have to go through iTunes. Who is Apple to say what I can and can not have on my iPhone? Yes, I'll admit, my iPhone has been jailbroken, but that's just me and my twisted philosophy. This has a price to pay, though... The iPhone is a highly closed platform, and Apple gets to say what you can, and can not have on it. The result is a rock solid platform that is ready for practically anything, snappy as the first day you bought it. Just try doing that in your classic Windows CE handheld. My friends also have the choice; I give them my personal advice and my impressions of Linux, and I let them choose. Some might try Linux, others won't. Some could probably find what they are looking for with Linux, but others should clearly stay with Windows. That's what choice is all about.

When GMail came out, it was a major event. It was on an invitation-only basis, each person having a certain amount of invites, and sending them out to friends, who in turn could invite. Ingenious, really... Instead of opening up and beeing flooded by millions of users, the servers slowly grew in size depending on the amount of invites. At the time, I didn't want a GMail account. I already had a web-based account, and I'm not talking about Hotmail, Yahoo or some other type, this was a real account, paid for, and hosted with Packetfury. I didn't need GMail, I didn't need the @gmail.com email, I didn't need the backups, and I didn't need the size. I was a geek! I had my own domain! I made billions of backups! Times change. My first cell-phone was a monster. My last phone is too, but not for the same reasons. My first cell phone took batteries, real AA batteries. With it, I could actually call people, and also maybe send SMS messages. My latest phone is an iPhone. With it, I can find out where I am, see myself on an updated map, send emails, listen to music, play games, consult my agenda, publish useless Facebook statuses, find out where the nearest café is, and read the daily news. Oh, and I can also call people, but that seems secondary. I got myself an iPhone because at the time, I was an iPhone dev. Today, with the same choice, I probably would have gone for a GooglePhone, because I like Google. Anyway. On the iPhone, Google is omni-present. The search engine in Internet is Google. The maps application is GoogleMaps. I can add emails accounts, and GMail is in the list. They have tons of applications designed specially for the iPhone, so in the end, I took advantage of it. I created a gmail account. I then added the PF account to GMail, just to have a "backup". I then added a few contacts, you never know. I added some more. Then I found out just how good this can be on an iPhone... My iPhone now reads my GMail account, not my PF account. My contacts are synced to my phone in real time, including the details I added, and the pictures. I can also sync with Evolution, if I want a heavy client. My agenda is also synced, but I still have a bit of work to do on that... Onlymy personal calendar appears, not the work calendar. So here I am, all Googled up, and I'm thrilled with it. So much, that I rarely use my heavy client anymore. I can do practically anything right from GMail, and it works just great. Having a 3G card on my PC does help, though, I'll admit. Oh, and another reason. Their anti-spam filter is excellent. My phone no longer vibrates every 15 minutes with useless junk. Today, I use a lot of Google apps. GMail, Google Calendar; those are the logical two. I now have a Picasa account, and the software works great, even on Linux, natively. Google Earth is great fun too.This morning I was sleeping peacefully on the train, and the wakeup call was pretty violent. When I arrived at work, I found out that, yes, the train tracks are perpendicular, and very close to the runway at the Rennes airport. The A320 landing on top of the train scared the hell out of me. I use Google Code search when in need of a hand. My CV is on Google Documents, as well as a few administrative papers, "just in case". And before all that, before any other application... On the top right hand side of y navigator (Firefox, not Chrome, believe it or not), lies a widget, Google Search. This is where it all started!

For 3 months now, I've been creating a Linux system that is based on an Ubuntu, but that is modified so that it works well on Netbook systems. The processor and RAM are below average, and that is understandable since the system is designed to be low-powered, but my biggest concern hasn't been the CPU or the processor, it has been the hard drive.
SSD technology has been around for some time, and today's disks are little more than updated USB keys, or compact flash systems. When it boils down to bare hardware, the common denominator is NAND flash. The building block of NAND FLASH is a transistor; one transistor per NAND cell. There are two variants, Single Level Cell (SLC) flash that can store one bit, and Multi Level Cell (MLC) flash that can store two. Typical timing for an SLC cell is 25µs read time, 2ms erase per block, and 250µs per write operation. For an MLC, typical results are 50µs read time, 2ms erase per block, and 900µs per write operation. The read time is identical; 25µs to read one bit, 50µs to read two. Nothing strange here. The erase time is constant, since an erase operation will erase an entire block (more on that later), but the write time does change. Writing to an MLC cell is almost 4 times slower than a typical SLC cell. Faster disks will tend to use SLC, and cheaper drives will use MLC. The P-SSD1800 uses MLC. Most desktop SSDs will use MLC, and most server SSDs will use SLC.

Ubuntu 11.10 is finally out! I haven't played about with the final version yet, but I'll be installing it this weekend. I've been using the alpha and beta on my new netbook, and I've seen quite a few changes from 11.04. The kernel 3.0, whuile not necessarily a major change (just a versioning number) does have the changes necessary so that video works better on the AMD 6200 video chip. I've already tried Neverwinter Nights, and it seems to run great. The alpha did, of course, have its share of bugs, and hopefully all of them have been corrected, but I'm confident. The only bad point is that I still haven't grown used to Unity, and even after forcing myself to use it exclusively for a week, I still don't like it. Now it looks like the new version will need a bit more taming... Anyway, more news on that next week! I'm going to install it (officially) on the netbook, replacing the alpha, and seeing what happens.
