Can someone who is a domain expert comment on this statement I see being repeated often about Jio's ability to have a significantly lower cost structure by offering only 4G service…

Few questions from reading the docs: 1) How big can all the colocated data for a single primary key get before they don't fit within a split? Can I implement a GMail-like product w…

It's simply due to the competitive hiring environment for the best software engineers in USA. The difference in pay cannot merely be explained simply by the difference in cost of l…

I have been through this several times. There's never any advantage to you revealing your current salary. No company is ever going to reject you because you didn't tell them your c…

Why won't the thieves disconnect the GPS/reader from the zipcar after they have broken in? Is that actually tamper-proof?

Ok so you can deduct as much as you want from any 'capital gains' you might have but only are allowed to deduct a max of $3000 per year from regular income, and the leftover capita…

What happens when after exercising, you sell the shares for a lot lower than the EV the year after? Can you claim a loss and deduct the loss from the taxable income the year you so…

Your resume is fine (just make the GPA more obvious - convert to 4.0 scale or something). I've worked at some of the companies you mentioned and I regularly do technical interviews…

Well he's pointing out EFS is not a replacement for EBS. You can run postgres on EBS volumes with PIOPS.

Amazon is way ahead of everyone else in the cloud space. Their closest rivals (Microsoft & Google) are pretty much copying AWS. Most of Azure's services are equally proprietary and…

Tuning consistency levels for your requests (R/W/N values) can only guarantee read-after-write consistency at best. It doesn't guarantee strong consistency like what HBase provides…

Since the emails are not encrypted, anyone in the middle who's capable of scanning this traffic can basically see all the transactions passing by?

I worked at AWS for a while. So a lot of times when I've been in such meetings, the 6-page document was actually full of technical details (design docs, product FAQs, post-mortem r…

Disclosure: I work on the Redshift team. The OP's cluster is a 16-node hs1.xlarge cluster (has 3 spindles per node). There's actually a more powerful node-type hs1.8xlarge which ha…

First of all, it's spelled career not carrier. PHP vs Ruby is not going to make a big difference. What matters is how you good you are. Listen to your parents and go to college. If…

I just went through the H-1B process and moved to USA in the beginning of this year. I'm not an American citizen obviously and I also studied in a university outside America. My an…

They generally ask for the full academic transcript (which has grades in it). Btw do not be worried if you don't have stellar grades/GPA - USCIS doesn't care about that. Your immig…

Btw it's illegal to make an employee pay the USCIS H-1B visa fees (USCIS website clearly mentions that the visa fees strictly has to be borne by the employer). I'm surprised that s…
