Recently I found myself working with an S3 bucket of 13,000 csv files that I needed to query. Initially, I was excited, because now had an excuse to play with AWS Athena or S3 Select — two serverless tools I been meaning to dive into. But that excitement — was short-lived! For some (as yet unexplained) reason, AWS Athena is not available in us-west-1. Which seemingly, is the only...
Image from wikicommons. The Serverless framework (SF) is a fantastic tool for testing and deploying lambda functions, but it’s reliance on cloudformation makes it clumsy for infrastructure like DynamoDB, S3 or SQS queues. For example, if your serverless.yml file had 5 lambdas, you’d be able to sls deploy all day long. But add just one S3 bucket, and you’d first have to sls...
First a definition. A lambda function is a service provided by aws that runs code for you without the introducing the complexity of provisioning servers of managing Operating Systems. It belongs in a category of architectures called serverless architectures. There’s a whole slew of folks trying to define with is serverless, but my favorite definition is this. Serverless means No Server...
As a company, Grab has done enormously well for itself, and naturally will be the target of some hate.
But I think there's a deeper issue with Grab that needs addressing before it becomes an unsolvable problem.
Android TV boxes, are computers that stream content from the internet onto your TV. The difference between them and your smart-phone is that it has a HDMI connector to your TV, and it usually comes pre-loaded with software to illegally stream content. While the boxes themselves, are general purpose computers running Android (the most popular OS today), the real focus of any regulation should be...
I’m still deep in my lambda love affair. Here’s my talk at the AWS meetup in SG on Lambda layers :
2018 in review I started the year building out govScan.info, a site that audits .gov.my websites for TLS implementation. Overall I curated a list of ~5000 Malaysian government domains through various OSINT and enumeration techniques and now use that list to scan them daily. The project stalled around Jun/July, and it’s basically on auto-pilot till I figure out what to do. The scans still...
Shutting Down!! Sayakenahack was undoubtedly the highlight of my 2017. If you’ve come from sayakenahack.com, I’m sorry but I’ve shutdown the site :(. I learnt so much from it, and it was even my ticket for presenting at Hack In the Box Singapore … But all good things must come to an end, there’s no point having a site that does nothing but consume my hosting charges...
Over the past few weeks, I’ve been toying with lambda functions and thinking about using them for more than just APIs. I think people miss the most interesting aspect of serverless functions — namely that they’re massively parallel capability, which can do a lot more than just run APIs or respond to events. There’s 2-ways AWS let’s you run lambdas, either via...
GitHub Webhooks with Serverless
Just because you have webhook, doesn’t mean you need a webserver.
With serverless AWS Lambdas you’ve got a free (as in beer) and always on ability to receive webhooks callbacks without the need for pesky servers. In this post, I’ll setup a serverless solution to accept incoming POST from a GitHub webhook.
