I recently interviewed at a major technology company. I won't mention the name because, honestly, I can't remember whether I signed an NDA, much less how strong it was.I did well. Mostly because of luck. I normally step over myself when I interview. I guess I've improved over the years. Here are a few tips to ace your own interview.1. Don't write on the whiteboardWhen I interviewed at Palantir around 5 years ago, I had a lot of trouble with this. Yes, I knew next to nothing about compu...

  Deep inside ARM's new Intel killer

ARM has swung a one-two punch at Intel's plans to muscle in on the smartphone and tablet space that's currently dominated by the plucky chip designers from Cambridge.At press soirées in London and San Francisco on Wednesday, ARM announced both a design for a tiny new chip, the Cortex-A7 MPCore, and a system-on-chip scheme that will marry the new A7 with the much more robust Cortex-A15 MPCore, which was announcedlast September and which should see the light of day next...

  How to create a language in one day

About a year ago I worked on a very interesting project which involved creating a unique world with all its history, people, physics, metaphysics and so forth. I like fictional worlds that are thoroughly created and I have always marveled at people like Tolkien or Richard Garriot who go such great lengths and even create languages for their worlds. I have since many years felt that it would be awesome to create my own language and I’m probably not alone in feeling that.When I started stud...

  Design Secrets for Engineers

If you are a designer like me, you must be asked on a regular basis to “make it look pretty.” The request can stroke your designer ego, making you feel like a design rockstar with super powers to make this world a more beautiful place. This is especially true at startups, where you are one of the few, maybe the only designer there. However, it can also be really annoying–almost degrading at times. Thoughts like “why the hell can’t engineers do this on their o...

  Eight C++ programming mistakes the compiler won’t catch

C++ is a complex language, full of subtle traps for the unwary. There is an almost infinite number of ways to screw things up. Fortunately, modern compilers are pretty good at detecting a large number of these cases and notifying the programmer via compile errors or warnings. Ultimately, any error that is compiler-detectable becomes a non-issue if properly handled, as it will be caught and fixed before the program leaves development. At worst, a compiler-detectable error results in los...

  The Story of W&L: China’s Great Internet Divide

Here’s an introductory quote from The Story of W&L, a tale of China’s great internet divide: China does not have one so-called “national internet,” instead there’s a great divide. It encompasses the elite with ThinkPad laptops and also the grassroots with MTK Shanzhai mobile phones. Our elites are on par with America, while our grassroots are on par with Vietnam. This is the story of W&L, two representatives of China’s great internet divide. T...

  Go Error Best Practice

Being indulged in Go for quite a while and having implemented web-related programs, grpc interfaces and Operators, I seem to be an advanced beginner now. However, I am still a raw hand in production-environmental debugging, which is cumbersome if done by querying logs or error messages. Imagine the scenario that a full-text search is called when the specific location of the error log is missing. Then what happens when those error logs are not only in one place? Yes, my error logs can no longer h...

  Fear of Ignorance

This past week, I was interviewing a candidate for a VP role along with two of our engineering leads. Everyone in the room excluding myself was classically “technical” – they could write code, had experience solving hard software problems and a background in computer science. I wrote my last line of PHP in 2004, and it had to be rewritten by a real programmer within 6 months.During the interview, we had the following exchange (due to an imperfect memory, I’ll ...
