What is a VLM?

If it is a public company, their SEC filing should reveal how much they paid for the acquisition.
vinothgopi··on Ask HN: Xray cost – USA $200 (13000 INR), India 1000 INR – what causes 10x diff?
Adam made an episode explaining medical costs and why it is so high. It will at least give you a different perspective into the system.

So adding on to the labor/fixed cost increase, prices are just inflated since insurance pays for them anyway. In India, people don’t really consider insurance for such routine work due to the hassle of processing the claims too.

vinothgopi··on How to handle Differences of Opinion
I think this is a good link to another article I read recently talking about what makes a good CEO. It is not about whether a CEO makes a decision, but how quickly he can make it despite the lack of all the data and convincing the rest to follow him.

Arguments/discussions are good, but a strong leader is needed in the end to draw a conclusion and figure out an execution plan.

vinothgopi··on Jawbone is being liquidated as its CEO launches a related health startup
To be honest, bluetooth was not that reliable until recently. With the new 4.x versions of Bluetooth, things are a lot more stable with audio devices. So I wouldn't blame Jawbone alone.
vinothgopi··on Show HN: Monica, an open-source CRM to manage friends and family
How about an option to organize family as a family tree? That's something I'm looking for currently.
vinothgopi··on Ask HN: 8 years working, now 3-4 months off to learn. Looking for advice
What happened to Geohot? Any links?
vinothgopi··on Show HN: Checkup – OSS tool for simple, self-hosted health checks
This is interesting. Can we use custom headers/auth when setting up the APIs for health checkups?
vinothgopi··on Crashing, Burning Planes Don’t Stop Passengers from Grabbing Their Luggage
This has been a big discussion point everywhere - about shocking this behavior is and how people's lives are at stake. But let me offer an alternate perspective, and maybe some insight into their behavior.

If you lose your ID or any other official documents in India, everyone knows how much of a hassle it is going to be to get these documents reissued. Of course the possibility of bribes to move the papers. Insurance claims for lost baggage? I wouldn't rely on it. It might take them a while to save up to buy whatever they might have in their bags too. Laptops, tablets etc. They probably don't earn that much to begin with. This is probably what ran through their minds.

Yes, lives are more important in the end and every second counts in such a scenario. But as an individual they might think - hey, it takes a few seconds to grab my bag and jump out. That would save me SO much trouble. Unfortunately that's what everyone thinks and in the end everyone goes for their bags and waste precious time.

vinothgopi··on An unexpected journey, a Postgres DBA's tale
I don't think I’ve ever read a tech blog post that was so gripping, with twists and turns AND ends with a cliffhanger (until you click on the link to part 2)
vinothgopi··on An unexpected journey, a Postgres DBA's tale
Amazon RDS is the managed version of Postgres (among other flavors of relational DBs). Maybe you are confusing it with Redshift.

vinothgopi··on Airtel is sniffing and censoring CloudFlare’s traffic in India
Yes, the OP mentions in his post itself that all ISP customers get the same message from Airtel.
vinothgopi··on Netflix Is Now Available Around the World
I'm a little confused.

Map shows very few countries - no Singapore as mentioned in the article

Also the article mentioned 190 countries at one point and 130 at other places. Moreover, Netflix claims it has 70M subscribers across 130 countries. How is that possible if they just launched it?

vinothgopi··on Show HN: Real Time Black Friday Dashboard – using Perl, Postgres, Geckoboard
Our entire data processing pipeline is actually written in perl (that is several 10s of thousands of lines of code). So is the subcomponent that actually pipes the data to Geckoboard.
vinothgopi··on Show HN: Real Time Black Friday Dashboard – using Perl, Postgres, Geckoboard
Geckoboard part was relatively easy - they have a nice interface to design beautiful looking dashboards.

Main magic was in the data pipeline. We tagged products that are Black Friday specific as seen on the merchant specific "Black Friday" category pages and other aggregators. These sites' pages were checked and the products' prices updated more frequently than our regular pipeline.

Everything ran as part of the Semantics3 infrastructure but at the last step we piped the updated information of the Black Friday specific products to a separate Postgres DB as well and that allowed us to run fancy queries that could answer almost any kind of questions we have about the data.

vinothgopi··on Show HN: API for price notifications for ecommerce products
Hey! Semantics3 has always had a solid database of products and pricing information which we keep constantly updated across various retailers. The Push API is just another interface to that database.
vinothgopi··on How I started BetaList
I was honestly out to thrash you guys in the comments when i read the title. But the article indeed turned out interesting. I guess this is what people have now termed "growth hacking"!
vinothgopi··on Show HN: 2048-as-a-service, an API to build complex 2048 based apps
tl;dr paste this in your console for demo

perl -e 'my $host = "http://2048.semantics3.com/hi/";my $cmd = "curl --silent -L $host"."start";my $output = `$cmd`;my $session_id = $output;$session_id=~s/.?ID:\s(\w+)./$1/si;my %keyMap = ( 'w' => 0, 'd' => 1, 's' => 2, 'a' => 3);print STDERR $output,"\n";while(1) { print STDERR "Input (w - up, a - left, d - right, s - down):\n"; my $userInput =<stdin> ; chomp ($userInput); if(defined($keyMap{$userInput})) { $userInput = $keyMap{$userInput}; } else { print STDERR "Invalid move.. w - up, a - left, d - right, s - down\n"; next; } my $cmd = "curl --silent $host"."state/$session_id/move/$userInput"; my $output = `$cmd`; print STDERR "\n$output\n"; if($output=~/Message:/si) { exit(0); }}'

vinothgopi··on Ask HN: What's the best "Contact Us" email address for a startup?
Well it is a little unfriendly (many emails to remember?) but I think it does help. While in a small company we tend to have overlapping roles, slowly our roles become more concrete. When that happens, a mail to say payments@ will immediately tell the payments guy that he has to do something although many others may be cc-ed. Or it may tell the customer that sending a mail to the specific topic email address might get a faster response.

Secondly, like how we all know that company.com/about usually takes us to the team page, the press might try to hit up press@. There is always a fallback - the contactus@ but when the number of emails start exploding, it helps when tagging emails by purpose.

vinothgopi··on Why Mac users don’t rant about the OS
Well mac users do rant too. A lot actually.

If not for the title, I think you do have a point here. I've had a mac for close to 6 years now and after each installation/upgrade, it feels like I'm back on my old laptop - nothing seems to have changed drastically. And that is a great thing. You get back to work faster knowing that things have been improved under the hood.

vinothgopi··on Google Shopping API closes next week: do you have an alternative?
Looks like Google has been shutting down features and apps that they think are not core to their business after the management shuffle and Page took over. And in their defense the announcement came pretty early.
vinothgopi··on We'll Be Back Soon
What's the fun in a rolling restart. It's probably Apple strategy to bring down the site and get some speculations up every time this happens.
vinothgopi··on Did PayPal Just Clone Stripe’s API Documentation?
They all use a document generator: http://jashkenas.github.com/docco/ (MIT License)

That is why they look so similar.

vinothgopi··on Semantics3 (YC W13) Is A Massive Consumer Products Database To Rule Them All
Sure I'll check out balancedpayments.com :) We should definitely talk! Hit me up at vinoth at semantics3.com
vinothgopi··on Semantics3 (YC W13) Is A Massive Consumer Products Database To Rule Them All
Well that doesn't make any sense. All our use cases would be violating our own ToC then!

What we meant was you cannot resell the data. We shall fix the wording of that ASAP. Thanks for pointing it out.

vinothgopi··on Semantics3 (YC W13) Is A Massive Consumer Products Database To Rule Them All
Thanks for the comment! Since amazon.com storefronts cover more products that the rest, hence the skewed results - this is specifically true with the long tail queries. As we add more sources, the dominance would be less pronounced :)

We did hear that feedback too. Hopefully our API helps mitigate that issue. Hit me up at vinoth at semantics3.com if you'd like to talk about how our API could work for you!

vinothgopi··on Semantics3 (YC W13) Is A Massive Consumer Products Database To Rule Them All
We started off adding most of the major e-commerce stores. As to how we decide which sites to add, well that depends. We usually add sites based on what our users seem to be asking for. More sites means more ability to do interesting queries like comparing the prices between store A and B. Since we have the products disambiguated, it is much easier.

Or if we find that the existing data that we gathered from our existing sources for a certain vertical could be improved, we add new niche sites to augment the data that we already have.

We started out in Singapore and the only payment processor we could use there was Paypal. If started now we would have used something more easier and better like Stripe :) That being said, we should be switching over to them soon.

Why so you say so? PayPal allows payments through their account and payments with credit cards without an account too.
