the force is with you but requires control

Either we are natural artist or we have developed skills to that end. In any case artists need instruments to channel the force. In digital art the tool of choice could be as clumsy as a mouse or as sensitive as a pen. With my drafting background I got used to drawing with a mouse. Mice are adequate for drafting which is more akin to vector drawing. Vectors are all about lines with end points, connected lines to make shapes and shapes filled with color. Of course it all depends on the type of drawing and vectors do tend to be rather precise.

Drawing with a mouse is like drawing with a bar of soap. Being the average input tool, many of us are used to using a mouse. Drawing with a pen is so awkward at first, it requires a lot of tweaking to match the working end to your way of drawing. The genius of todays pens is that they can simulate pressure and mimic most any drawing tool, brush, ink pen and airbrush. So, the software does one part and you control the other part, as to the line quality. Digital pens require a tablet to transfer the magic to the screen. Pen and tablet is by far the best combo for digital art. My advice, buy Wacom stuff new or used, especially if you are using Linux. Linux has a Wacom driver project and the drivers work well. If you are using MS Windows or Mac, your choices are a little wider. The whole point of a digital pen and tablet is simulating natural drawing instruments. Trying to tweak the pen and tablet and software for the right feel is the trick.

I have a vision of one day using my laptop in remote locations sporting a built-in pen tablet and focusing all my energies into my artwork. Believe it or not this is hard. One reason is the PC can do so much, seems a shame to dedicate one PC to art work alone. As soon as it is connected to the net or internet or you click a non-art application icon your PC transforms into other uses. I lose that artist focus and artist mystique and who wants to have a PC that only does one thing?
Yes we always have to recalibrate ourselves to make things fit us or us things.

Then lets get to the part they don't show you in the movies, actual training. It's hard to believe the force is with anyone when you first hold a digital pen. The best approach is set it and draw and ask stupid what if questions, and don't forget to read stuff. Online searches will yield how-to info, tutorials, but if you don't play with it, you'll never harness the force. The force is different with each of us and to make it flow effortlessly we must practice till the software and the hardware are transparent or second nature to us. Think of a jazz musician who has a tune in his head. If he doesn't know his instrument well, he simply can't make it play what's in his head. That is the whole point, tools are a channel a shaping instrument. I like your humming and air guitar but can you play that on a real guitar in real time? Your fingers need to feel the strings, you must apply that english to bend and stretch notes and use silence with sound to create drama. So, you must do equal amounts of serious study with serious play. Fooling around is skill building and discovery. Don't get lost, study and play.

I am also looking for kindred souls, because when you have a group you can challenge each other by encouraging help. You can inflame egos and put them out too. When you leave the group to do your thing, you are not alone. That is called community. It's good to venture out, good to come home to friends. You can calibrate yourself and break the rules, because you got a baseline.

Linux desktop light saber of choice.

Most of my life I have been thrust into jobs I wasn't quite up to the task. You learn on the job, notice holes in your armor and fix them. To date I am not a Linux system administrator in the corporate world. The title implies that all Linux users should have those skills. The fact is that many of those skills aren't needed to care for a single PC, yet when Linux is explained they are customarily unleashed upon new users. I purpose a fork in the System Admin moniker to focus on the skills of desktop maintenance. A Linux Desktop Admin would be a wonderful focus. Though some skills may overlap, it would make things clear to users who need no clue about the depths of server work.

A concise how-to set up a Linux desktop would be wonderful. With live-CDs this is almost instant. But certain things are not always so clear, like configuring sound cards, video cards, embedded sound and video, Linux only networks and of course wireless. Mixed platform networks are well documented.

I've been struggling through several Linux distros trying to find one that would work on my ancient Win98 vintage laptop (Gateway 4026gz). I've tried a dozen or so and most fell short in one way or another. Fedora 9 and 10, OpenSuse 11.2, Xubuntu, Ubuntu, Elive, #!Crunchbang, Mandriva, and a bunch more. The final choice was Ubuntu 9.10.

The reason was setup. Even though all the other distros had strong points, when it came to setup, I was able to setup wireless and sound with ease in Ubuntu. I don't care how savvy a techie you are (savvy = macho), if you are a typical desktop user, setting up wireless and sound should be painless. Like step one scan hardware, step two apply drivers, step three test system, done. Ubuntu has a System Testing module that test various systems that require drivers and protocols. This makes it easy to change drivers if the present one doesn't work.

The reason being not every Linux user is going to be an OS mechanic. The whole idea of a popular Linux is not to dumb it down but make it so it takes less specialized configuration knowledge. Still, if that deep tweak is your passion, your ma-cheese-mo glory, you can do that. I have seen many compile every kernel and application to make their own distro because they could. But please don't think I'm not a true believer because I don't compile. That works for you but not for me. Linux users no longer have to be extra savvy to use it.

So, in my experience I have suffered through many very good looking Linux distros that didn't have the conveniences built-in that Ubuntu has. But Ubuntu is so bloated, it can't run fast! What does fast mean? If you have the resources, it is fast enough, else you need to shut down services, get a leaner desktop or try another distro that suits your needs. That zippy fast distro may require hand tweaking of config files. This is just like sport cars, many like them, few buy them (real need over speed).

Now if you are still hooked into "Linux the sacred OS" it is still there, only now the desktop GUI has been well developed. You can click an icon which is a shortcut to a script or command that runs a function or app. I don't have to remember and type a script or command. I capitalize on the work of others to save me time, effort and mental band-width. I am quite impressed with the variety of Linux desktops, and I can change it if I am not.

further revelations in Jedi training.

I am used to working at a desk, even at home. I need a PC to be up and running all day long. To this end a desktop PC is fine. I have an old laptop that no longer charges the battery, it overheats and shuts down. I don't have experience running a newer laptop all day, I would hope they are engineered better. I have several desktops in my computer room, I can't use them all at once to any real advantage. So, I am thinking of putting one in the upstairs, one in the living-room.
This means I will have to get wireless cards so that I can avoid stringing cables all over the house and LCD screens (they take up less room). I plan to keep my working data on flash drives or devise a file server on the network.

There are advantages to being mobile, but I'm not in the habit of taking my laptop out into the public space. Laptops are energy lean and space saving, regardless. At home the desk is my peaceful place, other spots are too busy, I can't concentrate so good or feel I can stay without interruption.

Users are a strange lot, their PCs an extension of their personal strivings. I've met ones who retreat into a gaming closet, ones who game everywhere and  families of gamers. I've met small business owners and folks who bring work home. I know some IT people who seem more involved with networked systems than single PCs. And a few who are just plain geeks, like me.

Computers run cars and spaceships and weapon systems, I've met a few who are into those areas. The scariest people are the ones who don't need nothing but a cell phone or PDA. The iconic figure of a person hunched over a keyboard and staring into the glare of a monitor has nothing on a PDA/cell phone user seen everywhere. We have virtually invented the virtual phone booth. We are in a crowded mall, shoulder to shoulder, the cellphone rings (buzzes, clicks, chirps or jams), we evoke the cone of silence as if walls of glass surround us.

Mark my words, first the cell phone privacy force field, then the cell-portation device.  People will get lost in the network and their DNA recaptured on a server. Soon DNA sequences and digital technologies will be parallel, then merged. Doctors will convert you to a DNA stream, run you through a filter and reconstitute you healthy on the other side. All divergent DNA will beamed into space out of the galaxy via laser or stored in giant underground server bunkers. Prisons will be replaced by server farms. So behave yourself or you'll get the bits blasted out of you or you could wind up as a PC operating system in a robot.

Meanwhile, back at the Linuxville chateau, I am wondering how I got in this PC business in the first place.

We are making progress

Right here in the heart of the city, my local public library is making progress. Aside from the flurry of Windows 7, Microsoft Office version whatever and Photoshop books, there is now a spanking brand new GIMP book. This is the GIMP Bible by Jason van Gumster and Robert Shimonski. I am excited because for years Photoshop has ruled the roost with 50+ books and it cost how much?? GIMP does what most folks would use it for and it is free. That's free for folks who have no need to purchase professional level software just to tweak family photos and dabble. I also saw two new Open Office books. Open Office is also free and I am speaking especially to you students who need word processing but don't really need or can't afford M$ Office. Go figure, a public library with a truck load of software books on software no one can really justify the cost of and very few on freely available software. It is even more tragic because open source software is 100 times better than the freeware of the past. And quite a lot of it is enterprise quality, yet not fluffed with fancy trimmings and embedded security problems.

Even if you love or are work bound to Microsoft Windows, Open Source Software can relieve many mental stress fractures and plug financial black holes in wallets and purses. I always hear from ones who try open source but it doesn't work well in their situation. These are usually business folks who rely on Microsoft products and folks with the name-brand loyalty thing. I also see so many who would greatly benefit, who are clueless. Why clueless? Because Open Source stuff is not on the store shelf. Open Source doesn't have that cute mind sticking advertising thing going on.

I have lots of tutorials by users and videos but, I still do not own a printed GIMP reference book. I have PDF docs and users guides and yet there is something about a printed book that is handy and reassuring. Still I am like most, I lightly use many kinds of software. Of late my realization is that to do graphics I need to get more in-depth experience. And if you profess to know anything of anything, people expect you to be somewhat an expert. Sorry folks I use what I use the way that I use it. I am open to learn new tricks if it's something I can use. But overall, GIMP expert and graphics guru I am not. Let's face it, there are some who like to be seen as authoritative. For me to do or be that I would have to study all kinds of stuff I am not interested in, then make myself available to you. In that case I would definitely write a book.

This brings up another good thing, community information. Linux and Open Source both have a history of posting up-to-date information on the internet. And much of that information is maintained by the whole community of users, not just the authors of the software. This is because uses often find innovative ways of using and redefining intent of a software. They discover bugs, flaws, shortcomings and devise work-around, patches, scripts, customizations, tips, etc, The community from the noobe to the developer/maintainer all put in to support software. This is not true with customer/client based commercial software.

So, getting back to GIMP or any other software application, If you want to use it either dabble with it or set aside some time for structured learning. If you can not find a formal class or hire a tutor, I tell you the online and downloadable video tutorials are the way to go. You might find a surveying Open Source Software class before you find a specific class for Open Office or for GIMP. If you have a local computer group, use that as a focal point to gather like interested people and start a SIG (Special Interest Group). Even if you just have email communication, the fact that you are pursuing together is great encouragement and support. As a friend of mine said to me, "if you want to learn IT, hang with computer geeks." To associate and commune is great for learning stuff. This is even more appropriate for graphics because we need to show and tell.

The cool thing is that you don't have to use Linux to use Open Source Software. Some will run on Windows, Linux and Mac. The point is it is out there and not different than other software doing the same thing. It may have a different look and feel or have more or less features but for sure you won't need a defibrillator to revive your wallet.

the dead zone, revisited

Ever gotten a piece of hardware as a discount or a gift for a favor or even in lieu of cash? Your excitement is off the chart, until you explore what you got. How many times the big thrill became an albatross, the proverbial white elephant or my favorite, the door-stop? Believe it or not, lots of Linux users have experienced this, because Linux is supposed to run great on old stuff. The caveat is hardware with proprietary drivers (made for Microsoft OS).

In the further adventures of "This old PC", my Gateway 4026 laptop has reached another milestone. I've read about dozens of 4026 owners ready to convert their laptops into Frisbees after trying to install Linux on them. Here's what I did. First the total XP, then dual-boot via normal installation. This yielded a laptop with working XP and a silent off-line Ubuntu. Then I installed XP with Ubuntu installed via WUBI the Ubuntu windows installer. I had XP and Ubuntu joined at the hip. I discovered sound by installing the Alsa libraries (the Alsa Linux Sound Architecture), then interrogated the PC by Ubuntu's System Testing module. The sound jumped into life.

Next, since I discovered I could get sound, it was worth nuking the whole hard drive and installing Ubuntu by it self, goodby XP. This went great and I got sound and a wired Ethernet. Wireless, will I have wireless? There was a driver for the Broadcom wireless card, so I went with that. After I matched my card and access point configs, wireless happened and I pulled the Ethernet cable.

Here's what didn't happen. I popped in the Ubuntu 10.4 live-CD, it did not boot-up. So upgrading to the latest did not happen and since 9.10 is not broke and works unexpectedly well, I am not going to fool with it. By all accounts my Gateway 4026 is not supposed to run Linux and get sound and wireless. All I need now is a new battery pak and a new keyboard assembly, the resurrection will be complete. And I just tore off the "Made for Win98/XP" stickers and pasted on a "Linux Inside" sticker in its place, totally redefining the laptop in the mind of this user.

If you can get lower power consumption and reasonable performance, along with portability, then laptops, even larger ones are the thing to get. And there is something magical about Linux springing to life on a laptop. I am so used to ATX boxes stuck in one room. Break out the Glade new car scent air-freshener folks, we are new again.

padawan training - building a light saber

There are far too many ways to get Ubuntu on your PC.

1. the network install

2. the live-CD install over everything.

3. the live-CD run off the CD - take out when done - no install

4. Dual-boot two operating systems, same hard drive - two partitions

5. Dual-boot two operating systems, two hard drives

6. Linux on a flash drive

7. Linux as a guest operating system in a virtual machine

8. Used WUBI to install Ubuntu inside a XP folder.

WUBI is the official Ubuntu Windows Installer and It works!! Here's the story. My laptop a Gateway 4026 runs XP with all the stuff. I popped in a Ubuntu 9.10 live-CD and it runs but no sound. Then I boot-up XP and insert the Ubuntu disk to read it, behold, Wubi comes up and asks me if I want to install it into XP??????
This is not exactly a virtual machine but it makes a folder in the XP file system and formats that space to run Linux. So...........what I did was make a large windows partition and let Wubi put Ubuntu in it. Ubuntu installs just like normal and installs GRUB. I reboot, select XP or Ubuntu and have at it.

Ubuntu runs fine, no sound but fine. I went into Synaptic application loader, got the Alsa, universal linux sound architecture, hoping it would work. Then I ran the system testing stuff under System Admin. It found the sound chipset and now I got sound. I am so amazed it worked, old laptops are so proprietary.

There is something so magical about a laptop booting up to Linux. I keep saying the PC should be bigger. I keep looking behind the screen. Next I will look into the wireless connection, I've got a driver for that!

Jedi, no not yet, you have to face Vader

Who is Vader? Vader is when you must use your talents and tools on the fly. It's not a drill. But wait, let's not jump ahead so fast. Vader will look at your tools, your light saber and say your skills are complete, then test your knowledge of the force. How are your tools/skills? We are so eager to start slicing off limbs.

Click on the GIMP icon or menu button, it comes up and the Swiss Army knife of graphics applications is set before you. What do I do next? If you are serious about graphics and not just an occasional user, you need to put things in order according to your way of working. If you are doing animation, identify the animation tools, if painting, the painting tools, etc. This is suffering for the occasional user, "I ain't got time for this!" Imagine every time you want to pencil sketch, you have to find a piece of paper and sharpen a pencil. You also need a pencil sharpener and a flat surface to rest the paper on. If you have to do this every time, it gets in the way.

Presets is what it's called. Presets are used to save the adjustments to GIMP so that when you are ready to work GIMP is already setup for you. What would be immediately cool for GIMP and other apps like this is to have a number of prefigured and selectable presets. These presets or profiles or user preferences would include sets of tools for the kind of work. If I am doing 2D sketching I don't need animation tools, I shouldn't have to work around them. But I should be able to make and select custom presets according to the way I work.

Ramon Miranda is the man behind GPS (GIMP Paint Studio). This is a group of presets and files for painting and drawing. I am looking at this now. It is cool because when you are doing a kind of art process, you want the things you need handy. I am also looking to see if there is an easy way to save multiple setups or if I even need to worry about this. GPS is a good start.

There is another setup called GIMPshop, which is GIMP setup to look similar to Photoshop.  It tries to put menus and tools in the same place as in Photoshop, not to mimic Photoshop but to shorten your work flow while using GIMP if you are used to using Photoshop.

Now that you have a stack of paper, a bundle of sharpened pencils and a clear space to work, you can draw when the urge strikes, not having to prepare every time. And that's my point, you must spend time to get to know what GIMP can do, then tweak it so that it will do what you need it to do. No piece of software that has a wide range of settings is instantly intuitive. You set it up so that your work paths are short and your tools are not the obstacle to getting your ideas down.

Now the only thing left to do is to do it.

put the blastshield down Luke. stretch out with your feelings

You want to jump into Open Source graphic applications and you look to the experts for advice because they are experienced, right? I'm not saying they aren't great at digital graphics but.......so many former and crossed-over from Photoshop and Illustrator users are all voicing their frustrations along with their amazements. It's like wearing a too long for you open bath-robe and unsecured slippers while ascending the stairs. You get there by tripping on the robe fringes and trying to grip the insides of the slippers with your toes. Finally you get dressed, memory kicks in and you can climb the stairs blindfolded.

Not having used Photoshop, Illustrator or others, I don't have to work through re-programing myself. It is so obvious when an digital art wizard says GIMP is wonderful but.......it's not like......it doesn't have or do........not up to........not quite.....it still making strides...........not ready for mainstream, bigtime or serious projects in a paid work environment. An artist must suffer, but not like that. That kind of grunting should not be over emphasized in reviews. If you, an expert find switching over to use GIMP is hard, awkward, and not like whatever, how the heck do you expect a newbe like me with no history to grab it and use it. You struggled, it must be hard for everyone. Crap-da-monious nonsense!

I can't tell you how many times I've seen newbies, shell shocked and forewarned by experienced folks, get over it after they find they have no problem at all. They have no history, the learning curve has flat-lined for them. The real truth is most can deal with one all consuming graphics application, two or three gets complicated. It becomes apparent when one app becomes the favorite and you have to use or want to use another. Some people have more bandwidth than others. In all, if you spend enough time with one application, others are difficult to learn. I've been looking at GIMP for a little while, already I find Pixel, which has a Photoshop like interface, strange and awkward.

What if there was one Universal Graphics Interface and all graphics tools were third-party plugins? Won't happen too soon! Each graphics package does have some overlap. GIMP can do some vector and Inkscape can export to raster.

What's on my plate today? GIMP, Inkscape, Blender 3D, My Paint, Open Office Draw. What I need is more time with each one, away from the comparison mill. Perhaps I am risking my graphics career on Open Source graphics applications. I don't know if that thought is applicable to me, just that I am willing. As an artist I am committed to Open Source graphics as a starting point.

Hey Arno, how's the artist's eye?

The artist's eye is an innate thing. The problem I am having now is passion. Passion brings art to the top of your agenda. Passion allows you to work all things out so that you can do art. Also make the effort to display/promote/sell. It is a big thing to make the jump from art dabbler to artist in residence for profit.

There are all kinds of formulas out there and many artist are eager to share their experience as advice. Please share your experience, keep your advice. Why? There is no generic situation we art prone come out of or exist in, and there is no generic situation we are going to fit into. It might be different for an "art job" but crafty and fine art people usually don't have an art career tract in mind. An awful lot of us just art because we like it. We like to do art for a while without the "job" persona turning it into a dislike.

Commitment is another big hurdle. If you are like most, multi-talented and in the midst of immediate needs, it is often hard to focus on the thing you prefer when the things lower on your list are paying off and meeting your needs. Sometimes it's not about you but about your spouses view of the world. If I made big bucks from art, I'd be set with her. The more traditional jobs appear more a sure bet with her for now. I am inclined to agree, but also if you don't spend time to develop the preferred avenues, they remain on the back shelf and are destined to be regrets and I should'ves later. My wish is not to be supplied in living expenses yet unfulfilled as a person.

Opportunity is key to any interface with the world. There are opportunities you create for yourself and opportunities others present to you. There is always a cost. Time, expense, principles, inputs, outputs and consequences are all the currency of opportunity. The flip of opportunity is risk. You must risk some or all of yourself in hope of return or what's the point. Profit for you, for others, long turn, short turn, what ever is gained is because something was risked.

Do you have the passion?

Can you commit?

Will you choose and/or make opportunity?

Will you take the risk?

Are you prepared to deal with whatever the profit or return is?

The funny thing is that much of this assessment happens on the fly, while the play is in motion. As the things change, you make adjustments and move on. My hope is to stay in the game, go forward. It's about endurance and sustaining good play, not going down in a blaze of gory, I mean glory. Yet for others it might be different.

This is stuff I think about when I sit down, while in motion it's a little fuzzier cuz I gots others to care for. Endurance and learning to make art on the run.

you need a cyber plumber tool #z23.5 ver2, series 9rc

Ever do a plumbing project and it takes you hours because you don't have the tool to do the job easy? You run to the hardware store, the clerk says, "you need one of these!" It's just like the one you have but the head is bent over and the handle is really long. You reluctantly stick out your battered hand to fork over the cash. When you get back home the job takes 5 minutes.

Computing can be like plumbing. All the wires are in place but it's sometimes hard getting the data to flow where it needs to go. Here in the Linuxville guide office lab, I have a Compaq Proliant DL380, humming like a vacuum cleaner and my main PC (HP Pavilion a1030e). One runs Ubuntu 10,04 the other #!CrunchBang Linux (Ubuntu 9.04). I first needed them to share a keyboard and mouse. This is done via Synergy. Sort of a KVM in software. You run the server module on one and the client module on the other. The server's keyboard and mouse can now be used for both machines depending on where the cursor is positioned. In their specs, they say Synergy can cut-n-paste between server and client. I have not been able to discover how and if this works.

"Let them share data." There are so many ways to do this, FTP, NFS, remote, and others.......just get a little app called "Giver". Giver runs on both computers and they see each other through the network. Sort of like a data chat. Now I can pass files and folders back and forth with no effort.

Let's go back to the DL380. Why you got a big old rack mounted server in there? Well I don't really need it for a network resource manager or a user manager or web server. I could, but right now it's a beefy computer. Older yes, but it's got dual processors, RAID 1 disk array and I can learn a lot by tinkering. It needs more memory and there is no USB (I can get a PCI card for that!) and it is SCSI (scuzzy) inside. Some parts of computing you only learn by fingering the hardware.

So many techies only use computers to manage data. Caring for big and small data systems for businesses is fine. But since I worked as a drafter at NASA and seen engineers make boards from scratch and write software to run on them, I have an appreciation for "creative computing." I just wish I was smarter, techier, nerdier, etc. Also my fav movies are "TRON and Star Wars". For both of these movies, computers to produce the movies were invented as needed. They designed the hardware and software to do the jobs required. They were pie-n-ears (LOL) that's pioneers. I think that's the part missing with kids today. We want them to grow-up to be data managers, they resist (of course). It's like taking typing class in the old days. Creative computing looks more inviting. You can still manage a businesses data but the computer can do so much from remote controlling your car to designing your belt buckle (you wear a belt?).

And of course I will promote Linux. Linux does not put the $ and legal restraints on you. It is very handy when creative computing is before you. It will do the normal stuff too, quite well I might add. So with that, I take off, but take a look at these tools, next time you boot up. Guake Terminal, Synergy, Giver and the distro #!CrunchBang.

still in the lab - the next day

Back here in the lab there is great excitement, but I told you that already. Along with the stuff I got a few days ago, I procured two servers from a friend. Now what good is old servers? I can see your minds racing as did mine. But you got to think, if you don't know much about servers, you've gotta find out.  First of all a server is a "C", not a "PC" as far as hardware is concerned. A server in software can actually exist on any hardware it will run on. A server is the eye of the resource storm and is used to manage, direct, deploy, store, allocate, etc, etc, etc, connecting users to data. Don't take it personal, it's not a Personal Computer.

BUT when you pop the top, you find it's just like a "PC" inside. The hardware may be more robust or the divice connections different (mine is SCSI or scuzzy). So, what am I doing with? I have no web hosting aspirations, no need for business type infrastructure data processing configurations. The most logical thing for me was to see if I could use this advanced fire power for a "PC".

Well, it's got dual CPUs and a RAID disk array, needs more memory and maybe it will run Blender 3D better than my regular PC.

I tried a dozen different Linux versions on it. All the mainline Linuxes have too much whizbang to work. I tried #!CrunchBang Linux and it worked. It installed almost without a hitch. I had to exchange the CD ROM drive from one server to the other. Always get two junkers, one for spare parts!


The servers are rack mount sound like a vacuum cleaner and are designed to run forever.............................What kind? Compaq Proliant DL380.


This is why I have a lab and use Linux. Useful work is over rated, IT'S ALIVE!!!

day in the lab, the play by play

Gee, I am excited. The other day I got 2 flash drives @ 2 gig each. I used them for back up so that I could install Ubuntu 10.04 and still have my stuff. Then after that was done I put Wolvix 2.0.0 live-CD in, booted it up. Of course it runs great! Wolvix is Slackware based. I plugged in one flash drive, installed Wolvix on it.

I discovered my second machine wouldn't boot from a flash drive via the bios setup. Neither could my laptop, they are both older. It might be possible to boot from the flash drives using Grub the boot loader. My laptop has XP, will boot from hard drive or CD Rom. I will see if a MS platform boot loader is out there or install Linux inside XP via Wabi or something.

My second machine has XP and #!Crunchbang Linux on it along with Grub. I could write a config in Grub to see and boot from the flash drive.

I did however plug the flash drive into my first machine. Via the bios, I adjusted the boot sequence to see my flash drive. It booted without a whimper. It was totally weird not to hear the hard drive or the CD Rom revving and humming. In fact, if I had a LCD monitor there would be no sound, not even the clicking of my CRT going from blank to signal present. That was awesome.

Many of todays OSs have that Cylon style indicator going back and forth or a series of dots moving from left to right while booting up. I actually like to see the script being executed and scrolling. There is often a switch to turn it off/on called verbose. It reminds me of the "Matrix". There is something totally magical about seeing Linux boot up, especially on a laptop. That screen with the thin borders and black background and the text. That is the real face, the real software running, then it constructs the face or GUI to cover those inner workings. I still find that fascinating.  Some things in the PC world you can't fix or adjust via the GUI, you need to go deep inside, go behind the scenes. This is true in MS OSs as well as with Linux OSs.

I am in that gap between just running/using software and just managing data and monitoring systems. It's it called creative computing. A little hardware, a little software and let's try to do something besides mainstream use. Back in the day and not that long ago, hacking was a good term. Today hacking has been usurped and criminalized. The bad connotations of shared labels don't always defame the whole that do it. DIY home remodelers and backyard mechanics don't have a bad rap. Some how creative computer users get a bad name because "hacking" is easy to say and the consequences of bad guys/gals more visible. If it were not for hacking, there'd be no computer controlling and monitoring your car and other critical devices where humans can't stay awake 24/7 or be consistently vigilant on the job or in harsh environments, or handle the nuisances of media, medicine and entertainment devices. I can reluctantly give up the hacking label but don't criminalize all creative computer users.

No, "engineer" is a professional label. Many who have "engineer" knowledge and or ability are not pros in the professional sense. Some who have that "engineer" designation are evil doers, engage in "hacking", (if you will) and use creative computing as a means to gain access to  pillage and plunder. I am just fascinated by the technology and tinker and dabble. Some have a 57 Chevy under a tarp, I have some old/newer PCs, some build a shed, I a lab, some home stereo and multimedia centers, I could do that too! Hobbyist is an old school word or enthusiast more for today. When I turn on my lab the the neighborhood lights go out, I guess I've gone too far. OK, dressing in a Tux (Linux mascot) and passing out Gummy Fish to kids yelling "use Linux" is a bit much, LOL!

winds of change, but what's that smell?

OK, I just installed the latest Ubuntu 10.4 aka Lucid Lynx. Well it needs tweak'in and I just gotten to like the "Human" colors on Ubuntu 9.04-9.10. I was down with brown and being a brown guy myself, was groov'in on all things brown from rich Corinthian leather to chocolate bars. This purple haze thing is.........well good thing change is good.

Well, Ubuntu 10.4 is as fine as can be expected, boots a little faster, shuts down a lot faster. In between it is just Ubuntu which is very cool. But that Gnome Shell which I admired and enjoyed in the previous version does not work for me on my PC in this version. I am so disappointed, what a let down. Gnome Shell was very cool, yet needing some revising. I would have used it as is. It is coming but we will have to wait. Stay tuned for the sequel folks.

Why change? First of all let me say that change in Linux is normal, whether it is comfortable or not depends on how much work you have to do. This 10.4 version is what they call "LTS", which I think means Long Term Stable. Meaning it is the stable base from which minor upgrades will come until the next "LTS" version down the road. If you don't need to upgrade every whenever, you can just do it when the next "LTS" comes out and still be cool.

How do you prepare for change? Being a former Microsoft guy, now a Linux guy I think it is crazy to have one hard drive on a PC. With the advent of the thumb drive and the USB external drive, I think it is wise to put your personal files on a different drive than with the operating system and applications. This is very convenient for when your system crashes, the operating system gets hosed, you want to upgrade or you want to change. If you put your stuff on an external drive you don't have to back them up, just remove the USB and plug into another PC. Now if files are suspect you can remove them from the infected PC and scan them on a good one, and repair the OS separately or reinstall it.

For this change I bought two small thumb drives 2 gig each. I will eventually get a 4 or 8 gig for this file moving business. They are also handy for putting a boot-able OS on them, so cool. If you want a bigger thumb drive, the larger USB portable drives are better priced and bigger. I was at Best Buy the other day, a 1TB hard drive, that's one terabyte or 1000 gigs for $109.99 on sale!?! If your OS, apps and movie collection all on that thing gets lost because the OS crashes badly or you have to back up that big.......... sometimes even partitioning won't save you.

Now the question comes up, do penguins shed? Just like the guy with the bag on his head, you rip off the bag to find another bag. Oh, the other question, how do you like this new Ubuntu 10.04? It works fine, perhaps better, but the art work doesn't have the zest of the previous versions. I think we sometimes strain to be fresh and different. In the end a group of folks are trying to please the masses, which means the best part of Linux is that you can still change it to suit yourself.

job hunting geeks and HR filters

Ever wonder why they call it "state of the art" and not "state of the science"? 

While you're pondering, my realization is that I have been a computer user for a good number of years, and through that time I have become mildly obsessed. I didn't learn machine code, or Basic or scripting or wire wrapping circuit boards by hand. I have known ones who could boast in those skills. I'm just a button pusher fascinated by what happens when all the software and hardware are in place and you click the button, wow!


If you put this here and that there, does that work? What if you tried this or used that in a different context? My favorite is update older concepts, repackage them, use them in the present context. Why, because there are sweet-spots where everything seems to fit and work just right. A lot of times products off the shelf miss that sweet-spot. There are all kinds of different users so the sweet-spots are different. We all settle for what's close enough. Sometimes we are psyched into stuff because the advertising has brainwashed us. We complain because it ain't "sweet."

You find that level of computing you can understand, then the science becomes art. I had a friend, M. Booker. He had a dream job, at least to me. He worked for DEC Equipment in the heyday of the mainframe. He put them together and made them work. That was a job. Man, I envied him and marveled at his stories. M. Booker is a tad younger than I yet he was into computing way before me. Some get that chance to grow up with computers, that's why they are gurus and geeks. It's not weird, it's the same for auto enthusiast we call grease-monkeys, gear-heads and lead-foots.

My world is so strange, the people around me are so into stuff. They try to pull you their way or push you another.  Where you are at does not appear viable to them. I am talking as an unemployed person taking jobs as they come and advice. There are sweet-spots with jobs too. Most often there is sacrifice because the focus of the job and the energies spent are not always your ideal. But you do what you need to do to support yourself and family, even putting aside the sweet-spot. You flex and adapt and apply yourself at work, then at home you tinker, dabble and dream.

Going through school, getting a job according to that training, having a career, that is science. When life doesn't flow this straight or this smoothly it becomes an art. I do not know all I am capable of, I just know I have a habit of applying myself. I do not know everything up front and total recall or regurgitation of industry standards is not proof of ability. Experience is time spent in a focus. When companies insist on experience, they are not interested in your capacity to learn or your ability to apply yourself. They're not interested in are you familiar enough, they ask do you know it? Yes or No? Do you know the science?

They insist on science, but it is really an art? Especially with computers, every area is so broad. You have to go against what you feel is the realized truth to sell yourself, "Yes, I know it." Then they demand proof and spit out hypothetical situations to which you are to supply real typical solutions. "We want the science." I am an artist, won't really know till my hands are on it. When I am seeing the real problem and I am engaged in the process, then all my resources and energies and knowledge converge, I am blank and stumbling when you ask me now. My job is to get a job, not work the job! It's a different focus."

Some HR folks set the Rubic's cube in front of you and say fix it. They expect you to have autistic focus, as if they are not there, instantly grabbing the cube without emotion. Then expect a furry of twisting and flipping without bending the elbow. Ok Mr. Johnson, you can almost do it but you took longer than the industry standard. Can you explain?  Yes, Mr. HR, most of my experience of late is in trying to get a job, not actually working a job. Job seeking erodes and diminishes my technical skills by diverting my energies to skills I don't need when I have the job. Over time I wonder what's wrong with my job seeking skills and dump more time into that rather than keeping my job skills sharp. Then, every job I apply for in IT is asking for something a little different and they want experience. I can't know it all and you don't offer on the job training these days.

Meanwhile, back at the Linuxville guide office, lab and center for job search and part-time decompression chamber, life with Linux goes on.
Often I am downloading and running Linux live-CDs to see how well they run on my assortment of equipment. I fuss with ideas I learned in school or read somewhere or dreamed of. And I fix stuff of friends, most of whom only know Microsoft and never heard of Linux. They ask for Microsoft advice and wonder what kind of geek are you if you aren't a Microsoft expert? I'm a stranger in a foreign land, yes, but also being a desktop Linux enthusiast I am not too cool with the Linux server crowd. Some think the desktop is a dumbing down, I say I use a cup instead of a bucket, still I drink, same Linux, smaller portion.

coming to terms at last

My second machine has been acting strange ever since the hard drive bellied up. The new drive, a Maxtor 10 gig, is fussy, but then so are the two CD Rom drives that have to cipher disks. Older PCs are much like older cars, reliable when they run, but wear and tear show at odd times.

Xubuntu didn't do so good. So I whipped out my copy of #!Crunchbang. It sliced through my hardware like a clean knife and is a fast install as I ever seen. Crunchbang is Ubuntu based but has Openbox window manager. It is lean and mean with a stark black screen and white letters. You have to tweak it to make the colors come out but you don't want to spoil it. As my second machine I don't need it to do heavy lifting so I'm using it for doc storage and to play back video tutorials.

Oh yeah, Conky is on deck with this distro with it's on screen system monitor and a listing of keyboard shortcuts to make learning them a breeze. All it need now is Synergy to share keyboard and mouse.
I sense a GNU-vana moment approaching. It's an endless cycle upgrade, then learn new stuff, then make it better again, then fix when it brakes, then............If I had new stuff I would be bored, Linux just works, gives me nothing to do, so I tinker.

Now that was strange!

Ok, I gave it a fair shot and I like it but........
Wonderful thing about having two computers, you get to compare operating systems side by side. If you are immediately drawn to one or the other, you find out.

On the right, the home boy, Ubuntu Linux 9.10, sporting the preview version of the Gnome Shell. On the left various challengers including XP (he gets few calls these days).

Just installed a second drive on this second PC so fresh installs are the way to go. Xubuntu is first, I installed it and the little window size buttons and header bars did not appear or work. Gee, it worked before on this machine. The live-CD runs OK and I am moving windows around, but compared to the Gnome Shell it is extra work to get to stuff. Then another live-CD, Elive 2.0. This OS is a drooler, it is so good looking. Elive has compositing charm but no compositing. This means you can still run it on a low resource machine and get good performance. But wait, darn, I have a warning window that says ATI video cards are known to cause problems with certain drivers and may crash the system. It works but missing icons and quirky actions, drat that ATI. We'll have to try another video card and see how it goes. Elive 2.0 is still racing after the Mac type desktop but has the Linux toys, compared to Gnome Shell?

The Gnome Shell just sits there working with almost no effort (fewer mouse clicks). I don't have to set up shortcut icons and application launchers. I think the work flow is a little smoother. The big shock is accepting how it's setup, you know how Linux users are fiercely resistant to being told what to do and how to do it. The good thing is that so many other desktops exist. I hope if the Gnome Shell becomes the standard, that the windowing desktop folks are use to is not thrown away. Then you can put regular or decaf in the session selector when you log in.

What's strange is I like the Gnome Shell over the what we all are used to in windowed desktops. It reminds me of Konqueror, the file manager/browser/viewer that could do so much and was under appreciated, basically the only thing I liked about KDE. And also a little bit of Matisse desktop, which was mostly in Mandriva Linux. To me, this is what a PC is all about the file manager. Having access to my files is the most important thing, then the program menus. So how to get there has to be short with fewer distractions. I didn't like compositing because you had to "find" a working setup yourself.

Linux is wonderful with all the choice, but the selfish arrogance of some vocal users hampers wider acceptance. A better solution would be configuration recipes posted that other users could immediately appropriate. This way the folks with simple needs can better find their way and the boasters can still show off with gusto. Science is about repeatable results, not just being the first and the most extreme. Community is about forging the way for others also, else wise you are adrift on your own iceberg (global warming anyone?). 

There is the glitz of all kinds or screen manipulation, multi-touch, immersion 3D........... then there is making present technology and user habits more efficient by changing the beginning premise. You can do this in Linux. KDE almost did this and you have to like the way they made it customizable. But KDE is too fidgety. Everytime the cursor passes over something there is possibility for unwanted change. Gnome Shell is more static feels more stable. When I click, I know what to expect. I found the same thing when comparing KDE's BasKet Note Pads to KeepNote. They both allow text and pictures, but BasKet Note Pads requires care because things move and float. So a program can run stable, but is it stable in the user's hands. If the program feels sure in the user's hand, they have confidence to use it more often.

Gnome Shell is cool but make it a standard "option".

Gee, that was fun, lets do that again!

Here am I doing my blog thang, 
Nothing new here, but let me zoom out some:
Lookie there! What is that? It's called the Gnome-shell and it is as snazzy as snazzy can be. It's going to be in the newest coming Ubuntu with the Gnome desktop and it's a turn-around from the regular windowed desktop we love and loath. It's handy for me because all the windows we are used too are working me to death. While I liked the icon bar and the kind of Mac OS look this is more better, more functional for me. And you thought that flashy new Win7 was something, puh!

I won't spoil the fun for you, these are all the pics you'll get from me. You'll have to search for the previews your self. But if you can't wait, like me, I found it in the repositories via Synaptic. Now the standard warnings apply, read the home page and learn what you can do with it, how to start and stop it and take it for a spin.

Why am I impressed? Because the last two years we've been caught up in an eye-candy flurry called compositing. Gee, how much power does it take to do that? Lots of memory and a graphics card with muscles and oh wait I see the Enlightenment desktop beautifully doing fancy desktop effects and it's fast and efficient, without compositing. Too much of anything is mind numbing. The Gnome-shell gives me a cool way to approach my files without layers of configs and shortcuts. I like the way it guides you to use all those workspaces Linux is famous for. Even I got that MS Windows habit of putting stacks of open windows on one desktop. Man, I feel like my hands were untied.

So, a tip of the ole penguin flipper to you Gnome-shell developers, you did good.

It was an inside job.

Well my LCD monitor de-rezzed for the last time, I whispered to myself', "I need to take it apart to see what's wrong". There was a loud out cry, "No disassembly!?!, Johnny 5 is alive!!!"

A technician gets no respect in his own lab. I called the maker (HP), they grilled me according to their script. I kept telling them I am a certified technician, but they had to make sure I was grilled on both sides. Finally I got agreement that my LCD monitor was faulty. Then I proceeded to ask about the two circuit boards on the inside. The power board seemed OK but I wasn't getting a picture so I suspected the video board. Oh man, I could hear them thinking, "red alert, red alert, the user opened the case!" I asked the question simply, "Is it possible to purchase a new video control board for my LCD monitor?" It is a yes or no question, right? They insisted I just buy a new monitor. Dudes, that's very not green of you. Two or three emails later I got the "no way" response.

Come on, I am not talking about fixing a broken board, just swapping an old board with a working replacement. I have faced this in other areas like oven and washing machine repairs. There are certain consumer level repairs and then stuff so technologically complex and life threatening a credentialed specialist is required just to get the parts. The install is simple but you must understand the whole system so that if something goes wrong you know what to do. Gad, I'm so strained I need to degauss myself.

Taking the monitor apart I find the numbers and search the net. You know, it's cheaper to just find the same but used LCD monitor on ebay than find parts to fix the one I got. God forbid I learn something to keep what I own working. So I recycle the old monitor and they either trash it or test and reuse and swap out the parts. Gee, I can do that!
A techie gets no respect in his own lab!

Speaking of labs, I cleaned out my bookshelf, looks barren now. I got rid of old Win95, NT, Autocad 11, Office 95 books and others. The old Linux stuff I kept, lots of it still applies even though todays Linux is ten times better. I think that is a truism that MS totally changes to improve. Linux gets better but is essentially the same. It's the modular design of course. I can even get an up-to-date Linux with an older GUI if I wanted to retro. Right from the beginning Linux info was posted on the net. And that is where you will find it today. So the drive for eReaders for digital books and documents will well serve the Linux community. And that's a wrap for today, eWord up!

The candy shop and deep dabble

Man, I've been to the candy shop. It's called "DC Parts". It is wonderful though not as when I first went there years ago. Oh yeah, it's a computer parts store. It was like the old 5 and 10 with every nut and screw and clip and cable you ever saw. It is still a great place but today their inventory is trimmed a little. They got used PCs and laptops. I went today and got a 40 gig hard drive, some powered speakers, a USB cable and an audio cable. I had to leave quick, my wallet was empty and my eyes getting bigger. Man, that was a blast.

Well, the hard drive was a bust, so I went back a few times and three drives later got one that my bios could see. With used equipment, milage may vary. Good thing they exchanged it for nothing. Today I am so pleased, it works and I installed Xubuntu 9.10 on it. The PC has a second drive with XP on it.

 I guess I can call my computer desks a lab. I am always trying to move things into a more workable arrangement. My LCD monitor bombed out. The lower half had a yellow haze, the screen image was wavy like water, then the picture would go black after a few minutes, but I still had power. I set it aside, then opened it thinking the capacitors had burnt. I took the whole thing apart, put it back together. World of wonders, it works OK now. I really didn't do anything but it now works! How long? I think when I am not sitting in front of it I might turn it off, just to be cautious.

So this all works out fine. My main PC has the big CRT which is fine as the higher resolution is great for graphics. My second PC has the LCD display which is very clear. And I now have powered speakers for both PCs. One little thing I did, since my second PC has no front USB ports, I bought an extension cable. It is very awkward to reach under the desk and around the back of the PC to access a USB port. The extension cable puts the port on my desktop.

I am thinking of re-installing Synergy so that I only need one keyboard and mouse to use both PCs. Two keyboards and two mice on one limited desk surface is near impossible. I've typed stuff on the wrong keyboard into the wrong PC, funny but not fun.

Perhaps I need a server, that way I can store stuff in one location and not worry on which PC it's hiding on. You see this is what's so great about Linux and Open Source. You can move things around, change stuff and not fuss with activations and authentications and putting your paid for copy on more than one machine reprisals.

I am not a guru and not a noobe, yet through deep dabbling I have achieved Gnu-vana.

eh, that's a flower!?!

I have been working away trying to comprehend the splender of Blender 3D.

First let me say that surveying the landscape of Linuxville is a great thing, but........ you usually wind up with one of two things. The Linux Bazaar, hey look at this , look at that, try this, do that. OR deep in the darkest part of the network jungle, there lurks a circle of very hot servers cooking this Linux code and that code. Well, since I am a Linux user and a "personal" system admin instead of a corporate one, I want to show you what I brought home from the venerable Linux Bazaar. Why, because the applications are the whole mystery of Linux on the desktop. Folks rave about the Linux OS, you get the picture you can't do anything but server work. Let me tell you, servers don't need a GUI, or pretty wallpaper and you the average desktop user doooo! Even hardened text terminal gurus will have a desktop PC near by to have and behold a graphic file once in a while.

Also your personal activities are as valid to you as the data being managed in a corporate setting. That's what makes Linux so wonderful and it's called scalability. That's both to fit the range of hardware and also the range of user purpose.

My thing is digital art, not for some commercial venture (at least not yet) but for personal learning, personal adventure and experimenting. I will add that with Linux and Free Open Source Software (FOSS) you can not only start something with low or no cost, you can alter the code (if you have the skills) with no reprisals or legal harassment.

I started Blender 3D after years of hearing how hard it was to learn. What button do I push first? The secret is the bread crumbs left by ones who been there. Get the tutorial videos, play them till they make sense, the logic is subliminal, not apparent right off. While using it, it becomes clearer.

Here's what I am working on:
So far I learned to rearrange the windows, some basic keyboard shortcuts, what different commands and windows do. I am learning the feel of manipulating the cursor and scene, making and placing objects. What is that? That is what I call the Sunflower Dome Haus. Remember the cargo container home thing? Imagine 10 small cargo containers in circle the wagon style, then cover the middle with a dome. The space inside would be wonderful. And this is my other point, you can play with some ideas better if you can illustrate them. In 3D this is mind boggling and exciting. You may not build it in your backyard but on your PC, hummmmmm!

How does this compare with CAD drawing? 3D modeling may or may not be as precise as CAD but is definitely more efficient in working with concepts. Once you "get the picture" the details are easy. I tried Google's SketchUp, it is cool but no Linux version, that is sick. Ah, the road less traveled.

The other thing is weird. Once you start really using a Linux application, it seems you are all by yourself, everybody else is using some MS platform app. You need to peruse the Linuxville neighborhood and find some companions in the same pasture. Yes Martha there are warm weather penguins. They are the Birds in Black. They wear shades and make a PC look good!
