With digital attacks becoming rampant, the computer nerds who work for the good guys to thwart such incursions have become the new Navy SEALs - elite commandos who can carry out sophisticated operations on the battlefield of cyberspace.

Some law firms now use artificial intelligence software to scan and read mountains of legal documents, work that previously was performed by highly paid human lawyers.

Every new HubSpot employee has to go through training to learn how to use the software. That's a good idea, and it also keeps me from having to worry about what I'm supposed to be doing here or why Cranium, who hired me, still has never come by to say hello or talk about what he wants me to work on.

I think the issues around diversity of all kinds are really a huge problem in the startup world.

Remember the early days of the Net, when everything was going to be open and free, and we were all going to share information in a techno-utopia? That was great until people realized that their user data could be turned into gold. Now there are billions at stake, and nobody is playing nice anymore.

Mesh networking is an old idea. Oddly enough, the low-cost XO Laptop built by the 'One Laptop Per Child' organization - the so-called $100 laptop - was designed with built-in mesh networking. The idea with the XO machine was that many kids using those laptops would be out in rural areas without reliable Internet access.

My prior stint at 'Newsweek' was a very different world. So it's what it's like to be in one of these kooky software startups as a grown up. It's not entirely pleasant! It's like, 'Oh, I don't fit.'

To make a vehicle autonomous, you need to gather massive streams of data from loads of sensors and cameras and process that data on the fly so that the car can 'see' what's around it.

Fixing mistakes is one thing. Apple's bigger strength has been its ability to keep improving hit products.

There are too many ways that a startup gig can go sideways. If the startup won't agree to hefty severance, pass.

What if the Big Three automakers made products that were simple and easy to use - imagine a car with a user interface made by Apple - while also constantly trying to push the state of the art? What if they constantly sought out new technologies and ideas, and incorporated them into their products?

I wanted to write a book about what it's like to be 50 and trying to reinvent yourself - that struggle. There are all these books and inspirational speakers talking about being a lifelong learner, and it's so great to reinvent yourself, the brand of you. And I wanted to say, you know, it's not like that. It's actually really painful.

For the most part, cookies aren't dangerous. They were created so advertisers could get a better idea of who you are and what you're interested in, so they could send you ads you're more likely to find relevant.

Conventional companies try to find new uses for capabilities they already have. Transformers look at what the market needs and then go build it, hiring new people and/or taking people off other jobs.

You realize that if you're in the media business, technology is fundamentally what's driving the change in that business.

Nobody ever imagined how quickly the Android mobile-phone platform would take off - not even Andy Rubin, the Silicon Valley engineer who created it.

I was a technology reporter. And I think everybody who covers tech at some point or another feels like a little kid with their face pressed against the glass looking in at the candy shop and going, 'Wow, it looks so cool and so much fun.'

In addition to making Android available for free, Google also lets phone makers change the code and customize it so that an Android phone made by, say, Samsung has a different user interface than an Android phone from Motorola.

The people running Silicon Valley are not making the show because they want to do a satire of Silicon Valley. They are just comedy writers, and they want to make a funny show.

Google views Facebook as a threat to its business and has been trying to launch a social-networking service to compete with it.

I was drawn to journalism as a young guy because I felt like there was some purpose to it, not always but sometimes.

People in startup-land live inside it. They see themselves as really good people even when they're doing something that's very bad. There's a huge disconnect from reality in the tech world.

I was working at 'Forbes,' and I covered big enterprise companies - IBM, Sun, and EMC - and it was kind of boring. 'Forbes' only came out every other week, so it was not the most fast-paced job in the world. It was very nice, comfortable.

We like the John Gruber model - he writes some long stuff that's very thoughtful and analytical, and then other stuff, he just adds a bit of commentary. I like that.

Since the beginning of the internet era, it has been pretty widely accepted that when you join an online service, whatever data you put into it belongs to you.

Net-neutrality proponents howled when Comcast started throttling traffic from BitTorrent, a bandwidth-hogging program people use to swap video files. The Federal Communications Commission sided with the open-Internet folks, ruling that Comcast could not selectively choke off traffic.

I used to be a pretty hard-core iPhone fan. But over time, I grew more and more frustrated with the lousy service on AT&T. My iPhone simply could not reliably make and hold a phone call. Not just in New York and San Francisco, where I spend a lot of time, and where AT&T's service has been notoriously bad for years.

A startup job is an investment, after all: Venture capitalists may wager money, but you're staking something more precious - your time. And unlike VCs, you can't spread your risk by betting on a bunch of companies at once. Start with TAM. That's 'total addressable market,' and if it's not big enough, there's no point in talking.

The world of online marketing, where HubSpot operates, though, has a reputation for being kind of grubby. Our customers include people who make a living bombarding people with email offers or gaming Google's search algorithm or figuring out which kind of misleading subject line is most likely to trick someone into opening a message.

There was a time when a company could not sell its shares to the public unless its revenues were growing and it was turning a profit. Companies that lost money were deemed too risky for public investors.

PayPal, which was founded in 1998, may be the closest thing to a global currency that has ever been created. Based in San Jose, California, the company operates in 190 markets, sending and receiving payments in 24 currencies on behalf of 90 million active members.

'Do not track' probably won't spell doom for online advertisers. But it will put the burden on them to explain to consumers what targeted advertising is and why it's good for them. They'll have to come out of the shadows; they'll have to be honest with people. What a radical concept. I'm all for it.

There are people who do things in tech that have the same skill sets that journalists have. They write, they edit, they put out press releases.

Even in the business department of a magazine, tech was a backwater.

The Kindle app runs on iPads, BlackBerry, and Android devices, so you can read your books wherever you want; with Apple, you're locked into Apple devices.

The iPod Touch is basically an iPhone with the phone part taken out, which is fine - since making calls is the one thing that the iPhone doesn't actually do very well.

Apple is on fire, delivering smash hits across its entire product line. It's hard to think of another company that has ever been on such a roll.

To be sure, robotics are not the only job killers out there, with outsourcing stealing far more gigs than automation.

The iPhone is like 'omakase', the style of sushi where the chef chooses what you're going to eat, and might even tell you how to eat it - no wasabi allowed on this, no soy sauce allowed on that. Definitely no California rolls.

I often wonder what the world would be like if more companies were like Apple.

I want to get in on how the media business is changing, how people are telling stories in new ways.

Facebook's position with rival tech companies boils down to this: if you want access to all the information we've collected, strike a deal with us.

HubSpot's offices occupy several floors of a 19th-century furniture factory that has been transformed into the cliche of what the home of a tech startup should look like: exposed beams, frosted glass, a big atrium, modern art hanging in the lobby.

If your plumber or pool installer or local appliance store uses HubSpot software, HubSpot may be holding information about you without you even knowing it. We figure we're safe when we use online services. We figure we can trust the people who run them not to snoop on us. I used to believe that. I don't anymore.

Content is supposed to be king. But in the world of electronic devices, Apple seems to be placing the crown on its own head, apparently believing that its iPad and iPhone are more important to customers than the books, movies, and music they store on them.

There are two types of young people - the partiers and the people who wanted a sense of purpose in their life.

Hubspot's leaders were not heroes but rather a pack of sales and marketing charlatans who spun a good story about magical transformation technology and got rich by selling shares in a company that still has never turned a profit.

Nvidia's CEO, Jen-Hsun Huang, is an engineer and a chip designer. He cofounded Nvidia and still runs it like a startup.

I feel like Valleywag has been different things with different writers over the years. Up and down. I think it's at their best when they get a legitimate scoop, like when someone leaks them documents. I feel like we could do more of that, breaking stories.
