You know you have done either something big or something stupid when your ajax class is longer than a few lines.

Sun, 17 Mar 2013 21:27:28 +0530

This new thing I am working on has all the bells and whistles and the ajax class is more complex than I would like to admit. It connects to an injected chrome extension with elevated privileges to surpass content security restrictions. So the app can load any page with my authentication cookies, essentially avoiding the whole “Log in with website X” thingy. Scary, but since it’s all my code, I am not much worried. All of this means the ajax class is pretty elaborate.

And so begins the last day of my teenage life

To day is 7th January (in my timezone) and I will turn 20 tomorrow. The nausea is high, but today I started work on something I wanted to do for a long time. I don’t yet know exactly what it is but will know better as it develops.

Dear Asus India,

I am writing this letter after seeing a trend in the way you price your tablets. I am absolutely not interested at what prices you are selling your notebooks, laptops and motherboards, as a matter of fact, I have not even bothered to check the prices.

So long long time no post but I thought of an interesting experiment today. I am due for a system update so I wanted to figure out the bottleneck. Tried playing full HD movies simultaneously. It was pretty scary but it played 5 movies (with 100% CPU at 4th). Although i could see the jitters in video playback at the third movie. The clear bottleneck is my processor. There was barely a small bump in the RAM. So processor and graphic card it is then. Also hopefully a full HD monitor.

So today was the first day of Google I/O and they announced a bunch of things including Jelly Bean 4.1 and nexus tablet 7, nexus Q. Tablet is interesting and I would buy it if it were 10 inches. 7” just won’t cut it for me. The resolution could also have been better, it’s Google’s flagship device after all. 1080p would have been a surprise but a welcome one. They need something to rival retina display at the end of the day. I also feel bad that I am not in US to try all the Google Play stuff, also I am stuck on gingerbread, until i get a tablet or something.

How digital detectives deciphered Stuxnet, the most menacing malware in history

How digital detectives deciphered Stuxnet, the most menacing malware in history

A very very interesting and bone chilling read.

So I did knew about stuxnet for sometime and I had a vague idea that it was a nasty piece of malware but reading in detail of what it is, makes the hair stand on the back of my head. It’s interesting beyond any measure, especially for a geek.

Casually browsing Reddit and Hacker News today, I saw the same piece of news on both sites almost simultaneously. I clicked through expecting some political stuff. But it was not so much. It also linked to the page linked above. The article was very long, 5 pages long. But just a few paragraphs in, I was pretty darn sure I would end up reading all of it. And so it was. I read it and I don’t regret it a tiny bit.

The article describes how stuxnet’s compiled binaries were decoded and how the people who did it experienced everything around them at that time. And the creepy aspect escalated quickly once they figured out the malware somehow was related to Iranian nuclear plant and their two lead scientists being assassinated. Feels like a typical action movie plot, but it is all real!

The technology was mind blowingly sophisticated, or so the author states and I don’t feel like disagreeing with him. Not one but FOUR zero day exploits were somehow used in a single malware. That’s bad ass. US really wanted to slow Iran down. But how much genius went into creating such beast is beyond me. The kind of techniques used by stuxnet seems like taken from a very high budget, action-drama movie written/directed by a programmer. It’s so good, it feels wrong when you read it.

The environment in which such code would have been written also amazes me. What would it be like to be in a room full of smart people churning out revolutionary code. I used to think it would be very exciting to work at Facebook or Google and write code that people use, but then I read about this. This totally destroys the fun. It’s so interesting that it terrifies me. How would it be to wake up one morning and realizing that you were the one who wrote such code. Or you were the one who designed the architecture that can break into a number of computers without anyone noticing it.

There were alot of clever things about stuxnet. One of them being how damn stealth it’s functionality was. The fact that it changed the readings sent back to the control room is very interesting in itself. A good amount of work must also have gone into just making sure the code’s origin was untraceable.

I really wish stuxnet’s authors would come out and share their experience of creating it but I guess we all know that won’t happen.

Mon, 28 May 2012 13:55:49 +0530

Ok so I now have my first smartphone. Android, no less. During the years I have been an active internet user, I have heard time and again that smartphones/tablets are post PC devices. And I agree wholeheartedly. But I saw something today that reinforces this idea, and for good.

Google Latitude, I have always been pretty excited about it, but since I did not have a smart device until very recently, I was effectively locked out from it’s core features and the utter coolness that surrounds it. This idea that we can see real-time where someone is, is a nightmare for some people, people that care about their privacy (and there is nothing wrong about it) but tend to jump to conclusions without thinking it through. I, for one, don’t have any problem sharing my real-time location with few select people. And appropriately, I have an active friend list on Latitude but only a couple of them use their devices regularly enough for the intended effect to take place.

I usually have just two friends whose recent locations are shown on the map. The number is a bit underwhelming considering how many people have smartphone these days and how most of them have Latitude included among the bloatware. But the reason is that I believe the option to share location is not set by default, so most people don’t bother to check out the applications they have never heard of. Anyways, I went to a trip a couple of days ago without expecting much from Latitude since most of my friends didn’t share location. But what happened next had nothing to do with friends at all. In fact it was about a nifty little feature that, though very much makes sense from a programmer’s perspective that i have, pretty much blew my mind the moment I saw it in action. It’s called location history. It’s on latitude webpage under, well.. “Location History”.

The page has a map of all the GPS coordinates that phone went through, and places them in order of the time they were taken at. And gives an option to “Play” them in sequence like a slideshow by proportionately splitting time between different coordinates throughout the day. A screenshot of this should be above (or below). I know what it was the moment I loaded the page. I think I even knew this this was not only possible but a basic feature of a smartphone, but the real life experience beats any YouTube video hands down. There is nothing more amazing than to see what a few technologies can do. The implications are enormous. Stolen phone or proving innocence in a court seem to be a couple of the obvious ones.

I am very excited to have this phone with me. I know saying all this stuff that alot of the people out there have been using for sometime makes me look like some over excited child, but the experience of this and actually seeing the GPS arrow move when the car moves is out of the world of desktop somputers that I tend to spend most of my time. But that’s bound to change as I resume college I will be able to experiment with Latitude even more. For this trip I didn’t even knew this was happening otherwise I would have tried to give more consistent GPS feed so that the “Play” thing works without jitters of turned off GPS/in-active phone.

Also, it appears that the app even logs the location just when the app starts and doesn’t give GPS enough time to get more precise location. That’s the reason, I believe, of alot of ziz-zag lines I see on the zoomed in map, when in reality I didn’t move that much,. It appears that when the phone is used, the location is logged but mostly it’s the previous location that phone was used from and hence results in a sudden “movement” in the location history which never really happened IRL. That’s feedback right there, Latitude team, if you are reading this. But great product to blow mind of people who are savvy but have never used such stuff before

Soon to be Androidified!

Looks like I will finally have Google’s C# compiled binary on my mobile. It still surprises me that I didn’t already have it. But the device itself is pretty ok for the range. 800 GHz, 5MP (flash)/0.3MP, gingerbread, 512 gig RAM, 3.5 inch 320x480 TFT. Should be with me in about 2-3 days. I plan to have a better XOOM or Sony Tablet S down the road. Those specs are alot more appreciable but this Moto Fire is not bad for a mobile either. But I can’t hope to do heavy duty stuff on this. And this won’t get ICS either. Bummer since I don’t want to load a custom ROM. There are a gazillion things that i want to do but the current internet connection will take it’s toll at 256 kbps. Let’s hope I am able to upgrade before package delivers. I plan to get atleast 512kbps. Good thing is I already have a ADSL 2+ WiFi router so that is that.

Also I should probably start writing this stuff in a journal, blog does not seem to be right place for such stuff that has no particular audience.

Presenting Patch Count

Mon, 30 Apr 2012 05:08:00 +0530

I am a space enthusiast and I like looking at flashy images of stars. While looking at one such image, I got an idea to make an app that would count the number of stars in such image. Or to simplify, count the number of patches in an image. The app is a HTML5 web app, uses javascript and canvas with no external libraries.

Please have a look at the app wiki for details on how to use the app and how it works.

Live Demo:
http://achshar.com/patch-count
I suggest using “boxes” image first.

App Wiki:
http://code.achshar.com/patch-count/wiki

Source Code:
http://code.achshar.com/patch-count

There are still some issues with the algorithm. The call stack size exceeds if a patch is very big since algo uses recursion to count pixels. Please feel free to contribute :)

So I got Google Drive finally. It looks good and I have decided to keep it despite the fact that I am always looking to reduce the number of programs I have installed on my machine. I believe it’s worth it, at least until the novelty wears out.

There are a few glitches here and there, like all links/files open in IE and there is no way to change that. And one of my mercurial repository’s files are not being synced, rendering the whole thing useless as it won’t work on other machine.

I am looking forward to how it works out. And good luck DropBox. I heard good things about you.

RE: Technical = Coder; Definition of "Technical" can be rewritten.

Mon, 23 Apr 2012 04:32:07 +0530

I was reading an article on HN today that was titled Technical = Coder. Non-Technical = Non-Coder. You should have a read if you haven’t already. In the article the author says that people who cannot code should not call themselves ”Technical” when talking to investors or otherwise.

I agree with the gist of the article but I believe there are better ways to put the argument such that it does not disrespect people of other professions that can also come under the ”Technical” heading since the word itself changes meaning with the context.

So after reading comments at the article and HN, I have come up with two definitions of the word ”technical” that would seem to be more suitable in today’s start-up scene.

First: The person has a professional level knowledge and/or experience in the field that the start-up primarily deals with.

Second: If all of company’s assets* were to be taken away, the company can still produce the MVP with the said person and his personal resources** only.

* Like bank balance, employees, work-space, etc, excluding founders.
** Like knowledge, experience, home computer/laptop, etc.

If you fit the above definitions you are technical. I however think the second definition is more appropriate, although the first one cannot be discarded either.

Fri, 13 Apr 2012 22:11:34 +0530

Haven’t been writing for long time. Thanks, exams. I am still half way but this has been a roller coaster ride all the way. First, I had a chance to apply to start-up Chile but I stepped back on last minute because I didn’t know if I will be free in July or not, until the very last minute. I had the whole application filled with all the required documents. The only thing left was to press the “submit” button. But on the last minute I got to know that I did had a commitment that I could not ignore, (The school project) so i backed off.

Then the next day I get an email saying “your application is incomplete, reply to this email if you want to submit it, if you don’t your application will be deleted”. Yup this was after the deadline was over. I don’t know what went through my mind but I ended up emailing them to submit my application. That was not exactly the plan. But Then I though that if I burn alot of midnight oil, I might have a small chance of pulling both things off. (highly unlikely though)

Then I was studying maths a few days ago when I peeked into my Google Reader just for a second and I saw something I was not expecting. One word. Instagream. That was crazy. I skipped a beat. A billion dollars for a photo sharing app! “Not possible” I said to myself out loud. Then quickly turned on my pc only to confirm it. It was a crazy hour. 3 in the morning and a day after I submitted the application to start-up Chile. Not a good time to read something like that. But I had fun reading though.

The deal was good for founders. Hell it was great! They got cash + Facebook’s pre IPO stock. But the content, it irks me. A photo sharing app. Yes the community and user base has value too, and so does the team. But 60,00,00,00,000 rupees for a photo app with filter is just.. I don’t know, it does not feel right. But that’s the developer part of me saying, the entrepreneur in me thinks it was fair. The team did a lot of hard work, especially the back-end work to handle all those Justin Biebers and Taylor Swifts must be painstakingly difficult and not to mention, adventurous.

I would just say congratulation to Kevin and Team. I never got a chance to use the app but it must be good if it gets the kind of press it does. And let’s see what happens about Chile.

8 gig memory and windows 8!

Tue, 13 Mar 2012 21:34:53 +0530

Ok i finally got 8 gig ram for my system. Exam prep is on full swing which means less computer time. But I have managed to do some work on the school project and add achshar player to chromeextensions.org. Also the player is back in the store. There was some misunderstanding regarding some policy violations. But everything is fine now.

Also I have been using windows 8 for some time, the consumer preview. And I have to say it looks very good and is snappy and gestures are natural and it all makes sense. And I introduced my mom to win 8 and she seems to get it. But these videos on the internet make it seem that some people may not get it, I understand that but I believe the corners make more sense than a start button. A tutorial/popup regarding the corner is what is needed. I will stick to 8 for the foreseeable future.

Wed, 07 Mar 2012 22:52:42 +0530

So apparently my media player Achshar Player was pulled from the CWS. I am not sure why. I have replied and awaiting a response. This is not good. Here is the crux of the email i got.

Your Google Chrome item, “[Achshar Player],” did not comply with our policies on [Spam] and was removed from the Google Chrome Web Store.

This gives me 0 info as to why was the app pulled. My app was perfectly legit and did not even connect to the internet. How can it possibly “spam”.

The only thing that i can think of is probably the fact that it was a background app. But i used a feature that was available. I did not miss use it, at all. It makes sense for a media player to run in the background. It definitely does not fit my definition of spam.

Now i have to deal with confused users for whom app suddenly disappeared. Maybe they could have set some kind of warning for x days and then pull the app.

So i have been away from my blog for quiet some time now. And in all honesty, i can’t even convince myself to write that i will try to improve. What has been keeping me busy is this school project that i am head deep into. This project is tricky and in all manner a very sophisticated piece of work (for me, at least). But i have a gut feeling i can pull this off and that too elegantly. If it does happen, i plan to open source it once it’s finished. Making it my first open source project.

But before that happens, i have a shit load of work to do. The basic underlying code and internal APIs for the thing is ready and now i am working on the database structure of the project. It’s a fairly cumbursome task but part A of it is almost over.

I can’t speak anything about it yet but hope will soon be able to :) Also Achshar Player sees to be getting some traction again from some Spanish blogs and is about to get to the 2,000 user mark! yay!

So, long time no blogging. But i have been working full time (almost, college, duh!) on this new school project. And i am very glad i have all the experience because i think i can now handle any type of production problems with code and have proper backups and workstation setup. The new site is vast and very difficult to map on paper, so i will have to rely on the map inside my head at least until i have the basic infrastructure ready. Which is almost done BTW. I have a new multi-use dataset for presentation of data, a notification object and a dialogue mechanism. All with CSS3/HTML5. They really reduce the burden of compatibility. Also my google plus follower rate keeps increasing. Now steady at about 4600.

YC’s application is open again and i can’t decide weather i want to apply this time or not. I can’t leave the current work but chances of my selection are minimal so there won’t be much harm in applying. Maybe i will end up applying, HA!

Kill Hollywood, Not Movies

Sun, 22 Jan 2012 15:22:13 +0530

parislemon:

The fallout from the failure of SOPA and PIPA is just as interesting as the main topics themselves. First, many on the web with loud voices are finally waking up to how corrupt the lobbying/political system is in this country. Second, directly-related, there’s a quickly growing anti-Hollywood sentiment.

The most forceful stance has to be Y Combinator putting out a new RFS (Request for Startups) will one goal: Kill Hollywood.

It’s an important statement and message given the bullshit the MPAA is up to. But it’s also important to separate film, the artform, from Hollywood, the industry.

Haven’t been able to write for some time. But alot has happened. Happy belated lohri everyone! Also I was in the hacker news circle and my G+ follower count increased to 4400 in a couple of days! It was a fun ride. Also the Achshar player now gets about 1900 average daily visits. Plus CES is over and all the fuss about smart TVs apparently was just that, a fuss. Disappointed. Now looking forward to work on the (“super secret1”) new project :D

I also applied for Astronomical Society of India but no one responded :(
