amrithk··on This is why puzzle CAPTCHA's are wrong
Wow. I could never solve this in my first try...let alone in 29 seconds.
amrithk··on Ask YC: What percentage of the YC accepted come from Ivy League Schools?
I am not sure if the judges look at the schools the candidates come from. Maybe I am mistaken?
amrithk··on Anyone get this message when trying to access Facebook?
Ah. That makes sense.
amrithk··on Solving the problem of multiple writes to the database
Thanks for the suggestion. So I would basically write the pointer information (that would have been written to the database) to a temporary file instead? Do you think this improves performance significantly?
amrithk··on Solving the problem of multiple writes to the database
Thanks. It seemed to me in the beginning that HIDDEN fields were a very clumsy solution. Now I understand why they indeed are.

We use PHP as our server side scripting language. I was thinking of using the $_SESSION variable but attributes and pointer information for 30 image uploads per user * no of concurrent users seems like a huge drag on server memory.

I'll probably just write the pointer information to the database for now after each upload. It might make the web app slower by a few milliseconds but it reduces unnecessary complications

amrithk··on Solving the problem of multiple writes to the database
That's helpful. Thanks. Maybe I am overthinking too much about optimization. It doesn't seem like updating a bunch of columns with text will result in significant time savings.
amrithk··on Solving the problem of multiple writes to the database
Great. Thanks
amrithk··on Solving the problem of multiple writes to the database
Sorry if I am not being clear.

I am not uploading each image as a BLOB. Rather, I am storing a bunch of strings in the database that will later help me point to the actual image (which is first stored in the local webserver but is pushed into Amazon S3 after the user has finished with the form).

I want to avoid these multiple writes to the database (which stores various pointers to the image) and just do one large write operation at the end. Does this not matter? Would you know any benchmarking tools that will help me measure this?

Thanks

amrithk··on Solving the problem of multiple writes to the database
Also, I didn't want to write to the database each time someone uploads an image. I just wanted to queue all these writes and do it at once in the end when a user commits to make all the changes.

That would save some processing time right? Thanks.

amrithk··on Solving the problem of multiple writes to the database
Not sure what you meant. Could you elaborate? The form basically accepts input until a user reaches the 30 image limit. A user can then hit the confirm button if he/she is satisfied and wants to commit all the changes.
amrithk··on Any suggestions on what one should think about when scaling a site?
Great. These should help me get started.
amrithk··on Ask YC: Feedback on my startup - social media market analysis
Interesting idea but its a little abstract for me. Looking at the same queries might be helpful in understanding how this works but clicking on most of them gave me blank pages.
amrithk··on Advice on partnership issues.....
The agreement is really basic, spelling out what share of the profits each person will get. Of course, at that time, all of us understood that our ownership will be diluted based on any future investment that we might receive.

Looking back, we were incredibly naive and unsure about how these agreements are typically drafted although I have a much better understanding now.

amrithk··on Advice on partnership issues.....
No. We are not incorporated. We are not really a startup still. So far, we are just a bunch of guys working in a basement and trying to get a working demo ready.
amrithk··on Advice on partnership issues.....
Thanks, The consultancy idea might be a good idea when we get money.
amrithk··on Advice on partnership issues.....
Thanks for the suggestion.

Is it possible to come up with another agreement that voids the previous one already signed? What happens to the 10% we initially gave him?

amrithk··on 10 startups to watch
I liked the first startup as well Pinger
amrithk··on Ask YC: Domain Names: Better to be clear or witty?
Thats a hard one. Something witty will get you recognized if it sticks. But a lot of startups these days have 'witty' unusual names and it doesn;t stand out as much anymore. I would shoot for a straight forward domain name thats easy to remember and is short.
amrithk··on Your opinions on startup funding
Thanks for sharing the link.
amrithk··on Your opinions on startup funding
Thats interesting. All I hear about is VC backed startups so it is refreshing to see some self-funded ones. In my mind, it seems a startup can only be sufficiently self-funded if it has a viable business model. How has your experience been with this (given that one needs to be more creative in making money in a web setting)?
amrithk··on Your opinions on startup funding
Yup. I guess I need to start by creating a LinkedIn profile. Don't currently have one.

How easy is it to become a member? I am working with 2 other people to build a site during weekends. I don;t really have a bio online and it will take me a while to build up a suitable LinkedIn profile. Do you think this might be a problem?

amrithk··on Your opinions on startup funding
Thats an interesting resource. Thanks for sharing this.
amrithk··on Ask HN: Please critique my webapp
I like the preview feature (when you scroll on a link and it displays the media)

I would work on communicating your idea to the user. What is this website about? What problem are you trying to solve (like others have said)? I wasn't entirely sure until after 4-5 minutes. Many people will probably spend less time trying to figure stuff out.

Finally, from a design perspective, the website looks kind of bare. Splash it with complementary, warm colors (instead of having white space and standard formats for hyperlinks all around). Users will be more inclined to explore the rest of the site that way.

amrithk··on Ask YC: Is vim worth learning and why?
I have not used vim very much. I have a friend who does and it is his editor of choice. I personally use (and prefer) Notepad++. Its got a decent stable of shortcuts, loads up quickly, and works reasonably well with many languages.
amrithk··on File uploads with JQuery?
Thanks for sharing this.
amrithk··on Www1 vs www2 vs www3 etc
Sorry. This may be a really dumb question....but how do you make sure they are in DNS?
amrithk··on Using Amazon EC2
Any tutorials / services that show how one can get instance running up quickly? I am a newbie to this.
amrithk··on Using Amazon EC2
I develop in a Windows environment currently. I currently use S3 as a storage solution so I am somewhat familiar with Amazon's web service offerings. EC2 seems really compelling but I am still not really sure how it all works (how the MySQL database can be stored in S3, how databases can be replicated across instances so that there is data consistency etc).
