Epson 2200 in Snow Leopard
Posted by therider in Mac, Photography, Software on January 27, 2010
The upgrade to Snow Leopard a few months back was smooth, except for one fatal thing. The colors from my Epson 2200 went from awesome in Leopard to downright awful, thanks to the third party Gutenprint driver. I only realized this mess today since I had been printing black and whites using the Quad Tone Rip (QTR) driver which kept producing neutral prints.
So I hit google and there it was, a pretty long forum thread on the very same issue. To my surprise I found that Epson indeed released Snow Leopard driver for the 2200 printer sometime in Nov 2009. I installed it, then removed and re-added the printer and voila, the colors are almost back to normal. The interface is actually much better than what I expected, and the advanced color setting panel actually worked (it was mangled up in the Gutenprint driver).
Now that I still had a little magenta cast (as opposed to horrible), I tweaked with the advanced color settings panel. Took down magenta to -9 and suddenly the grays started to look like gray. There is just one thing to be done in photoshop prior to printing. The brightness of the image has to be increased a little bit. A foolproof way to do this is to have a curves layer, with no adjustment, then setting the blending mode to screen with 50% opacity. That makes my color prints about same as what I see on my monitor. For black and white prints using QTR, the last step is not necessary, or maybe about 20% opacity will do.
Looking forward to some print sessions in the coming days.
Update: Magenta -12 works even better.
Update: Brightness +16 nearly eliminates the need to brighten the image using a 50% screen blended curves layer with no adjustments.
New place, new woodshop
We moved to a rented house in the beginning of 2010. One of my two roomies moved out of the old place, and the rent looked pretty steep, so we found a 3br house for a little less. Besides the fact that all of us craved for some open space, the 2-car garage was a pretty good motivation to move my lazy ass.
It took us no less than a week to move and set up, but now I can say that it was totally worth the labor and pain. No more stair climbing nonsense, and my garage woodshop next to the kitchen is a total bliss.
Among my tools, I have only added a wood lathe and a bandsaw. As luck would have it, the lathe was my own over a year back and the current owner would not sell it but trust me enough to let me use it on rent. Could not find a good deal on craigslist so I rented it for 6 months. Who knows if my bowl turning passion will still be active or not. The bandsaw was a great find, and it makes me feel like I got a pair of scissors to cut wood in arbitrary shapes. Pretty darn fun.
Amazing how a little more space can fire up so much energy. I have taken up a little bit of acrylic painting as well, and anxious to see where it takes me. Painted my first 16×20 canvas last week and right now making a 24×24 hardwood canvas for another painting I have in mind.
Hope the creative energy stays on for a while. More later…
Stackoverflow.com: A programmer’s dream
While google has always served me to find answers to a wide array of programming and technical issues, I don’t recall any one tech QA site which was consistently reliable. I regularly dug out answers from google group discussions to some old bulletin board archives to the typical flashy QA sites infested with scammy ads.
Stackoverflow.com provides a spot-on solution to this very precise problem. Not only it is a clean and functional site free of annoying ads, it actually engages the users to help others more. The reputation scoring logic is a feedback loop, which gets a programmer addicted in no time. I think it works marvelously well.
To top it off, Joel Spolsky and Jeff Atwood, the founders of stackoverflow made their software reusable. There is also superuser.com and serverfault.com based on the same platform but geared more towards sysadmin crowd. And slowly, many other sites are adopting this very successful platform, for example: answers.onstartups.com.
I am very happy to be involved with helping the programming community and learning at the same time. I guess I have nearly stopped spending time on facebook and twitter. I recommend all my coworkers and techie friends to start contributing in these platforms already.
Epson V500 and coming back to film
Posted by therider in Photography on October 27, 2009
I used 35mm film extensively since 2003 till about 2005 when I bought my first digital SLR, a Nikon D70. In those days I was pretty much brainwashed with all the digital hype like everybody else. The film workflow was lengthy. Mail order slides and B/W took about 2 weeks to arrive. Good film scanners were expensive and did not seem worth more than a DSLR. I had to retire film for a while. Back in those days I was doing event and sports photography for the graduate school newspaper and digital was just the right tool for the task.
Fast forward 3 years. I live in the bay area, close to San Francisco and many scenic places. I occasionally photograph events and portraits but other than that I am mostly drawn to making fine art images. Not that digital can’t do it, but film imparts a special character to the process. Anyone who has seen glowing color slides on a light table or made black and white silver gelatin prints in the chemical darkroom, can immediately understand my point. Film is tangible, unlike digital files. You don’t need a computer to have fun with film. To enjoy the photography even more, I picked up a battered Mamiya RB67 medium format film SLR. I like it so much I am going to shoot medium format film for as long as it is available and affordable.
I have right now about 30 boxes of 35mm color slides, countless 35mm color and b/w negatives, and more than a dozen medium format slides and b/w negatives. And this collection is going to grow.
Glad I waited all these years for a good affordable scanner, and the Epson V500 can be considered the home run. Short of 4×5 scanning (I don’t think I have enough patience to go up to 4×5) this one has everything I need. I just did my first few scans and for the first time I was able to appreciate 16 bit black and white images. The tonal gradations are very tolerant of drastic adjustments unlike 8 bit where it would lose detail pretty quickly.
I guess it will be interesting to dig through my old films. Lots of memories from Long Island, and maybe a few surprise images. I will see.
P.S. I can’t deny the evil influence of my coworker Ken (@wirehead) in making me a medium format fanatic, not to mention his showing off velvia 6×7 slides of women in fishnets doing light painting in the middle of nowhere
Woodwork project: Desk-side shelf
I am not a neat-freak but chaos beyond a certain point seems to hurt my productivity and mental peace. My first serious woodwork project was an utility shelf, barely 6″ deep, 2 ft wide and 6 ft tall, but it served me very well for the last three years.
Recently, easy access to everyday things has been an issue, since Priti loves to do origami and by now we have a lot of them lying around. So I decided it was time to upgrade. Nice excuse to play with the tools for a few hours.
I came up with a 6 ft tall, 2.5 ft wide and about a foot deep storage with 3 fixed shelves and 4 adjustable ones. About 5 hours of back breaking labor but the feeling of extra space is so nice that it makes me compare to an upgrade of 1gb to 10gb of RAM !
For those who want to make one, here is a cut list:
1. 12″ wide white melamine panel with pre-drilled holes for shelving: 6ft x2 (I bought two 8 ft long panels since there was no 12 ft)
2. 12″ wide solid white melamine panel: 30″ x3 (bought one 8 ft panel)
3. 12″ wide pine panel: 30″ x4 (bought two 6 ft panels)
4. 1/8″ thick handypanel for backing board: 3 pieces of 24″x48″, then cut each to 24″x31.5″
I used pocket joinery and glue to fix the 3 melamine shelves first. The structure at this point is not very rigid, it can shear, leading to joint failure since melamine is not very dense. For the extra rigidity, the backing boards are glued and nailed behind. The adjustable shelves got notches cut where it sits on the metal spoons, to prevent an accidental slip out, by an earthquake or otherwise.
Oh and the total cost of wood from home depot: $80. Satisfaction of building a quality storage shelf for our daily use: priceless.
Wordpress fusion theme: twitter widget link problem
The twitter sidebar widget in the fusion theme of wordpress shows weird in Firefox browser, due to the encoding of the double quotes in the href attribute. For example, a link from a twitter post shows like this in source:
Safari in quite intelligent regarding this and displays the links right.
A look in the code revealed that the output from twitter webservice call is not completely decoded. The function fusion_TwitterWidget() in wp-content/themes/fusion/functions.php looks like this after an easy fix:
-
// theme widget: Twitter
-
function fusion_TwitterWidget($args){
-
extract($args);
-
echo $before_widget;
-
print $before_title.__(‘Twitter posts’,'fusion’).$after_title; ?>
-
-
<?php
-
$username = get_option(‘fusion_twitterid’);
-
$limit = get_option(‘fusion_twitterentries’);
-
if($username<>”) {
-
$feed = file_get_contents("http://search.twitter.com/search.atom?q=from:" . $username . "&rpp=" . $limit);
-
-
// joyd: fix for the broken hyperlinks of twitter plugin due to encoded quotes
-
// $feed = str_replace("<", "< ", $feed);
-
// $feed = str_replace(">", ">", $feed);
-
-
print ‘<ul id="twitterupdates">’;
-
for ($i = 1; $i < = $amount; $i++) {
-
print ‘<li class="entry">’;
-
echo $cleaner[0];
-
print ‘</li>’;
-
}
-
print ‘</ul>’;
-
}
-
-
echo $after_widget;
-
}
Thanks a lot to Francesco to point this out !
Fitness through fun
As I made clear in a few previous articles, I hate doing boring stuff. Using machines in the gym seems just one of those. Fitness, though necessary should not be a monotonous thing. The reason I don’t like the treadmill or the elliptical or the stationary bicycle is that while the body is getting a nice workout, the mind is sitting completely idle. People take their favorite magazines or look at some lame show on the gym TV. I just can’t afford to idle my mind, even for half an hour a day.
Enter the concept of fitness through fun. My coworker Ken (wirehead) is an excellent example. He hates the gym for the same reasons as mine. He took up bicycling 2 years ago and never looked back. He rides (both commute and fun) so much that sometimes he can’t recall when he last drove his car. He is back in an awesome shape and I now have a healthy dose of jealousy on his achievement. Now my problem is, even though I took up cycling recently, I just can’t get rid of my habit of working late on personal projects. Sleeping at 2am pretty much guarantees a frantic morning of a quick shower followed by dashing off to work on my motorcycle. So, back to square one.
But it changed this week. Quite dramatically.
Priti wanted to try out rock climbing at the local Planet Granite and just to make her happy I agreed to take up a 4-week course during which we could climb as much as we wanted. Looking at all the fit people around, I was more or less sure that it could very well suck for me. Lo and behold, all my assumptions were proven wrong at the first climb. I had no idea how much strength I had in my arms that I could still pull my weight pretty well.
We both bought shoes and harnesses on the next day. No point renting them since we like it so much. Priti did a few successful 5.8 climbs (for the definition of grades, see here: YDS) yesterday and I finished four consecutive climbs on 5.3 to 5.6 today. I just could not believe it.
My whole body got exercise. I had fun. Looking at the variety of climbing tracks here I don’t think I will get bored anytime soon. And then maybe we will go outdoors for more serious fun, plus photography as well. Now that is what I call fitness as a side effect and has the most ROI I can ever imagine.

Too many projects, too little time
I renamed my blog again. For the fourth time if I remember right. And I guess this time it is an honest title (title #1 “Motorcycle diary of Joy Dutta” – too specific, title #2 “Joy Dutta’s blog” – too boring, title #3 “Joy Dutta on work|play|life” — too cheesy).
I hate boredom since eternity. To stay productive, I had to make a safety net of hobbies that I can enjoy in a round robin fashion. In other words I simply rotate my activities in convenient intervals. Photography consumes the most of my free time and it is something very hard to be bored with. Despite that sometimes I am full of ideas to build physical objects rather than two dimensional ones. That is when I find the most pleasure using my woodworking tools to convert my 3D visualizations into a product. Those are the good times.
Even outside hobbies, there are many productivity tasks to be done. Too much progress is happening in the internet technology arena and it would be a career suicide if we software engineer folks don’t keep up with the latest ideas and workflows. There is non-stop learning and self-improvement opportunities which we must avail. We are living in exponential times and must deal with the ever shortening times to do even more interesting stuff.
My blog is really an attempt to jot down my productive explorations and life experiences. Tech tips, tutorials, ideas, homemade contraptions. You name it, you can see it here.
In other words, there is simply no time to watch the stupid TV !
The fraud called “Healthcare”
Less than a year. A few regular doctor visits and regular checkup tests. That is what it takes for the healthcare system to unveil its bloody fangs and other dirty secrets.
As the system works, we go to our family physician, pay $10 copay and the rest is taken care of. $20 for a specialist, which is still fine. A few weeks back Priti had to see a specialist for some consulation on a procedure. Desk receptionist checked my insurance card, I paid my copay and we talked to the doctor. After 15 minutes of consultation the doc mentioned some procedures but said she would first verify if my insurance would cover it.
Next day we got a call from her and as we feared, she was not covered under my insurance. So we thought, fine, we would find another specialist who can do the procedure while being covered.
The next bill from the Aetna caught us off guard. $350 charges for that 15 min consultation is NOT APPROVED ! Patients are not told if insurance covers the consultation but fees are anyway charged. Brilliant scheme, I must say. Sounds like the regime of Shylock, huh ?
It will be interesting to see how it unfolds from here. I have sent an email to my Aetna asking an explanation. Maybe I should also ask if they cover injuries caused by severe rectal trauma as well, assuming that is already a “pre-existing” case of most insured people in this country.
Update:
It gets even more interesting. In the words of a friend of mine:
I experienced a slight variation of this. My doctor called up the insurance and asked if the suggested treatment was covered to which they answered in the affirmative. I get a bill from the doctor’s office a year later with the charges. I inquire and they tell me the insurance declined to cover it later. I said that it was absurd to tell the patient that it was covered before the treatment and then shifting the cost to the patient later to which she applied ‘Yes unfortunately that happens all the time and there isn’t anything we can do about it.’
Update:
The doctor’s office called us and said not to worry about the $350 bill, it was taken care of. Cool. This is what I don’t get here. First, there will be bills of obscene amounts. Then the claim history will show that insurance paid a fraction of it or denied it. And the patient will remain confused about the real out-of-pocket cost for anything. So much for a first world health care system.
Woodwork project: Toy riding airplane
One of the major reasons I love woodworking is to build things of emotional value, in this age of rampant consumerism. Handmade heirloom wooden toys are something no made-in-china plastic electronic gadget can beat in terms of value and the sheer amount of fun a kid can have.
I wanted to build classic toys since I took up this hobby in 2006. I had to wait till my friends started having kids, but in the meantime I made a bunch of furnitures and gizmos to justify my addiction for tools. I did learn enough to design according to my time at hand, and turn it into a product. The hardest part is figuring out the exact sequence of operations. It is not uncommon to do everything well and then glue on the wrong side right before the final assembly !
I got this idea from John Michael Linck’s riding airplane model. I only needed to know the exterior dimensions and I designed the parts according to my own plan. I just hope my friend’s kid finds it comfortable when she starts walking in a few months.
For the curious, the wood is softwood pine. The top wing span is 24″ and the fuselage is about 28″. For the wheels I used omnidirectional casters from home depot. A jigsaw was needed to cut the curved fuselage. The round profile of the wood is done in a router after corner rounding on the drill press with a sanding drum. Joinery is mostly glue since I wanted to minimize screws on a toy. I hope it will hold.
Can’t wait to see this toy in action early next year. Maybe I will see a pilot’s logbook with imaginary flight plans very soon.
