In appreciation of Impulsesoft

no comments

Prelude

Back in the mid 90s, when I was still in college, I was an active member of the “Literary and debating society”, and we used to publish an annual magazine. In my last year in college, I wrote a silly sci-fi story about a chip designer. The premise was when the guy designed the chip, he instilled some sort of AI in it and when an enemy country stole the chip to build their weapons [using time travel nonetheless], it backfired on them at the last minute :-) .

The hero of my story was a classmate, Baskar Subramanian. I don’t remember if I wrote the story and made Baskar the hero or if I picked Baskar first and wrote a story around him. It really doesn’t matter – it was my way of showing how cool Baskar was, as a geek :-) . And boy, was I right?

Impulsesoft

Not too long after I wrote that story [4 years to be exact], Baskar and 4 of his classmates quit their lucrative jobs in Texas Instruments to float this startup in Bangalore, called Impulsesoft. Just before that I had heard that Baskar almost relocated to France and thanks the ultimate wisdom of immigration officials, got to stay back in Bangalore. They started off creating device drivers, moved onto bluetooth devices and created excellent products.

Seven years and many successes later, SIRF technology, a Silicon Valley based company acquired Impulsesoft, for about US$ 16 million.

So, what is the big deal?

you may ask. After all, startups are created EVERY day in the Silicon Valley and they make zillions more than what Impulsesoft did.

Heck, even my last startup, Collation Inc was financially more successful. Or was it? Let us put things in perspective to see why Impulsesoft is so special.

  1.   For starters, can you count the number of successful high tech product startups from India? How many can you count? India’s high tech successes have mostly been software services firms, fuelled by outsourcing. How many core technology companies can you count?
  2.   From what I understand, Impulsesoft never raised any VC funding. Part of which I hear was the risk averse VCs in India [yeah, risk averse Venture Capitalism - go figure :-) ], wouldn’t fund a product based startup out of India – since they perceived it as high risk.
  3.   Remember, we are not talking about a dot.com success story, fuelled by the stock market alone ;-) . We are talking about a core technology company that invents and created excellent hardware.

And I can go on and on. Bottom line – It is a difficult to create a startup, tougher to do so in India and even more harder to do a hardware startup out of India. I get asked at least once or twice a month by someone in the valley – “If you all say that India is as good as it is in high tech, why don’t we see them do as many startups or open source products from there?”. I used to beat around the bush in the past, these days I start by saying “So, there is this startup out of Bangalore floated by 4 of my college mates called Impulsesoft …”.

Yes, the Impulsesoft team gives us hope

I forwarded the Impulsesoft acquisition story to a bunch of my friends, many of them who had returned from Silicon Valley to India, either working for startups or creating their own startups. One of them said it best. “Glad to hear that your classmates made it. News like this is the encouragement that is required to keep the dream going”.
Stories like these don’t get big press in India, they are usually buried behind dot.com IPOs or some services firm hiring another 7,000 people. The focus of IT in India is usually misplaced in the body count, the number of people these companies hire. Somehow, the number of people who get hired defines the IT prowess and success of a company :-) .

Impulsesoft gives us hope. Hope to innovate, hope to succeed – no matter where you are, no matter what your obstacles are. Companies like Impulsesoft are those that are going to shape India’s IT industry in the next few decades. I can’t wait to see what the Impulsesoft guys do next :-) . Good luck folks.

Buying a LCD monitor for photo editing

29 comments

Update (Aug 2010)

My current favorite monitor for photo editing is the excellent HP ZR24W, you should also read my subjective review on that monitor.

The big guys

  1. Buy an Eizo if you can.
  2. Buy a NEC / Lacie / Apple if you can’t do #1. [Lacie is rebranded NEC and $400 more expensive]

For the rest of us, continue reading.

Find the panel

Find out the model you are in interested in and go here.
For instance,

  • Samsung 205BW (widescreen) has a 20 inch 6 ms TN panel.
  • Dell 2007FPW (widescreen) has a 20 inch 8 ms (g2g) S-IPS (LG.Philips LM201W01) panel.
  • Samsung 215TW (widescreen) has a 21 inch 8 ms (g2g) S-PVA (Samsung LTM210M2) panel.

Picking the panel

  • TN panel – fast response, 6 bit colors, BAD for photo processing. It has only 226,000 odd colors and it simulates the other 16.7 m colors. Don’t touch it with a 10 feet pole for photo editing. Trust me on that. I bought a Samsung 204B and without running any tests, I could see banding in the color gradients. Opening up a standard test chart tells the truth.
  • S-IPS – probably the best for photo editing, 8 bit per channel. True 16.7 m colors, great for photo editing, but slow response times. Usually the monitor is $150-$200 more than a comparative TN panel.
  • S-PVA – opinion is split on how good S-PVA is. Some argue [quoting websites written in 2004 that S-IPS rules]. However, the rolls royce of LCD monitors, Eizo uses S-PVA.

Eizo CE210W (widescreen) has a 21 inch 8 ms (g2g) S-PVA (Samsung LTM210M2) panel.
Pick a S-PVA or S-IPS panel with true 8 bit / channel. In the same flatpanels.dk site, look at the tests link and see if your monitor is testing. PVA [not S-PVA, but an old variant] is supposed to be inferior.

You can learn danish to read the page or look for clues Wink. Look for 6 bit or 8 bit. If the colors say less than 16.7 million don’t touch it. If it says 16.7 million, then it is good.

About backlighting and other stuff

Not all panels are made the same. For instance, the Samsung 215tw and Eizo CE210W use the same panel, but they are like many hundred $ apart.
You are at the sole mercy of online reviews about this one.
For instance, the viewsonic WS monitors have S-IPS panels, but their backlight leak is bad compared to say Samsungs.

Find out about the manufacturer’s history

Some manufacturers change panels for the same monitor EACH production run. For instance, the Dell 2007FP has gone thru a S-IPS monitor and a S-PVA monitor, so what you buy may not be what you think you read.

http://aryarya.net/wassyoi/lcdmemo.html

Dell 2007FP = 20.1 inch 16 ms S-IPS (LG.Philips LM201U05) panel.

Dell 2007FP ver2 = 20.1 inch 16 ms S-PVA (Samsung LTM201U1) panel.
So, buy it in a store where you can return easily. [Costco rules]

Test your monitor

Once you get the monitor, run through some simple tests. I ran it through Ron Reznicks tools files from his ebook and run chkmon

That hopefully will catch most of the problems.

So, what did I buy?

I bought a Samsung 215TW wide screen LCD monitor from Costco :) . Wide screen monitors are a bliss for photo editing.

Apple LCDs

If you want to buy an apple laptop for photo editing, you must read this first.

An excellent read

This thread is outstanding to learn about various monitor types.

A good list of LCD types

A good list of the type of LCD panels in monitors can be found here:

Wide gamut monitors

I recently bought a Dell 2408 wide gamut monitor which has a wider color space closer to AdobeRGB, but it has its own problems, particularly with Mac OSX.

So much so that I strongly recommend against any wide gamut monitor unless Mac OSX fixes these problems. If you are using a wide gamut monitor with Mac OSX on anything other than color managed Firefox 3.1, you are going to see horribly saturated colors, useless for just about anything.

As noted above, my current favorite monitor to edit photos is the excellent HP ZR24W monitor, I used this monitor to replace my excellent iMac 27″ glossy monitor, which should say something.

Cintre datasync, a review

no comments

I have been lugging my work laptop around to all my photo tours. Whenever I shoot for more than two days, I can use up my 2 GB of CF cards. I rarely delete my photos when I am on the road and I tend to bracket a lot. This with my added fascination of panoramas can quickly fill up cards.

I have been shopping around for a portable storage device for quite some time. I came very close to buying the PD7X but kept delaying the purchase.

I ran into this very interesting storage device, Cintre DATASync just before my Sierra trip. It was the least expensive option I found and read some favorable reviews in Nikon Cafe, so I bought a 40 GB device.

I now use this device regularly and it has served me well on a 3 day weekend trip to Sierra and a 6 day trip to Alaska .

Pros

  1. Very small. Comes with a neat leather pouch that smug fits the device.
  2. Least expensive of all the devices on the market.
  3. Looks neat :D .
  4. Transfers data from my 1 GB 80x lexar card in about 3.5 mins. Transferring about 4 GB of data from the device to my PC took under 8 mins.
  5. Fits easily into my camera bag. To me, this was a critical aspect. If this was not the case, it might as well be sitting in the hotel room.

Cons

  1. Does not have a built in CF card reader. Almost every other device in this category has one. I bought a $10 USB 2.0 CF reader and slipped it into the same leather pouch.
  2. No visual feedback in terms of numbers. The most expensive ones like Nikon coolwalker and the Epson have a big LCD that shows pictures as they are being transferred. The less expensive PD7X or PD70X at least show the number of photos and / or size of data being copied over. This device has a few LED lights. If there was an error, the error LED comes up and blinks. At the end of data transfer, if the device beeps twice, data was saved correctly, if it beeped four times, it did not save correctly!

Now con #2 is what should decide if you like the device or not. If you do not stay near the device during transfer and you missed the beeps, you have to go by the LEDs that light up. This may or may not work for you.

I have transferred photos about a dozen times so far and I like it despite the lack of visual feedback. I have learnt to trust the device. If that is a major factor, consider other options. If not, this is a steal and one of the very few things in this hobby that is worth the $ you spend.

Update

I got a couple of emails from users who had issues with this data storage device. I have no issues whatsoever so far. There have been instances of failure which were due to improper formatting of hard disks as reported here. In general, search for OTG in Nikon cafe forums, there are many threads about this device.

Real life usage

I used this device extensively on a 6 day trip to Alaska. I did not take my laptop with me. The device worked like a charm. Nearly 10 GB of photos, never had to recharge the device at all. Only thing I missed is a LCD preview feature :D . Another $300 more, I should get a Nikon Coolwalker or some for that :) .

But for the value this device provides, it is an unbeatable deal.

Update

The lack of visual feedback eventually caught up with me. I bought a PD70X as a replacement to this device.
