davidu··on “Sonicwall products are not returnable”
As an aside, you should never use a debit card online, ever, ever, ever.

Candidly, you should never use it for anything other than taking money out of an ATM.

davidu··on Google and Box Announce Partnership
That's frightening.

I would suggest your security team do an audit with CloudLock (note, we acquired them at Cisco) and my guess is that it'll be illuminating / shocking.

davidu··on Google and Box Announce Partnership
At a company of any size, with compliance and complex sharing requirements, and advanced search and workflow needs, Drive is a non-starter.
davidu··on A new reason to love OpenDNS: no more ads (2014)
Founder of OpenDNS here.

No idea how this is on the front page, this is literally years-old news.

We haven't shown ads or done nxdomain redirection for more than two years.

We are, however, probably one of the best and easiest things you can do to raise the bar for user security on the Internet. We're also part of Cisco now[1].

davidu··on AWS S3 open source alternative written in Go
Theory here is that people will build apps that talk to S3. But sometimes those apps might need to run inside the perimeter and can't talk to the cloud. So rather than rewrite an app to talk to a new internal datastore, you just point it at a locally hosted Minio and you're up and running.

Smart.

davidu··on NSO Group's iPhone Zero-Days used against a UAE Human Rights Defender
Yep -- This is legit security research. Excellent research.
davidu··on A year of Rust and DNS
Not quite. As legal explained to me -- it's too legally ambiguous for some entities to feel comfortable using because your only fall back on public domain is copyright, which can be overly restrictive, and the usage rights are undefined and enforcement or rights can be applied or modified at will by the copyright holder in the absence of a clear license. And that copyright, even in the public domain, often exists inherently.

That's not an issue for me at my $corporation because they are sane, but apparently that's the argument.

davidu··on US ready to 'hand over' the internet's naming system
They want ICANN to revoke domains they don't like.
davidu··on US ready to 'hand over' the internet's naming system
ICANN, despite its imperfection, is infinitely better than having control of the DNS by the UN or the ITU who are exceptionally self-serving and controlled by corporate interests.

Thought of course I'd have preferred it stay with DoC under its benevolent and almost entirely hands-off stewardship.

davidu··on How Silicon Valley's Palantir Wired Washington
That's really not accurate.

While it happens, there are many projects and efforts that are tightly controlled, managed, and executed.

And when projects go off the rails, people are generally pretty unhappy. The government is huge though, so bad apples and bad actors exist... but it's not accurate to write hyperbolically as you do.

davidu··on Provider of Personal Finance Tools Tracks Cards, Sells Data to Investors (2015)

davidu··on Optimal DNS Ad Blocker
Hardcoding DNS servers that are run on Amazon IPs on AWS is just an incredibly bad idea.
davidu··on Stuck in negotiations? Try Hootsuite's steak dinner clause
It doesn't matter meaningfully. While you're right that it changes the dynamic in the consecration of the terms, it doesn't change the deal drivers and the benefit shift in the execution of the contract.
davidu··on Stuck in negotiations? Try Hootsuite's steak dinner clause
This is not an acceptable practice and it's surprising a deal desk or CFO would sign off on this.

Credit Card fee negotiation results in a benefit or cost to a company. Steak dinner is a benefit to an individual. "Relationship building" activities are important, but should be treated separately and unrelated to contract negotiations and deal terms.

davidu··on Declined VC wants us to pay legal fees
There is no scenario where you should feel compelled to pay their legal fees. Perhaps they will think again before starting to run up a legal tab on a term sheet in the future.

That said, if this is a <$5k amount of legal bill… I might just offer to split it to leave cordially.

davidu··on Don't tug on that, you never know what it might be attached to
I read this, but seemed to skip over the part where he explains why this changed suddenly, when the behavior was documented?

What changed to make the perl become capable whereas previously it lacked the low port capability?

davidu··on The “Cobra Effect” that is disabling paste on password fields
This is so frustrating.

davidu··on Tumblr’s stumbles under Yahoo
I love Tumblr, but this article is a bit distorted from reality.

Tumblr was failing to execute on the revenue side of their business, both before their acquisition, and then after.

At some point, Tumblr had to try and become a business and not just a website.

This article points blame at Marissa, but shouldn't it really be pointing at David, or a team of leaders?

davidu··on LendingClub Loan Buyers Retreat After Shakeup; U.S. Probes
These stock grants will vest over time. The retention bonuses pay out in a year.

A lot can be done to turn the ship around in a year. If they don't, the stock grants (depending on issue price) will be worth a lot less than originally issued, and they'll mainly have a highly taxed bonus. The grants are to prevent opportunity cost of leaving from being considered.

If they turn it around, the stock grants will be easily worth it. The company was worth $3b+ weeks ago. Now it's dipped below $1.5b. If they can fix that, that's a small price to pay.

davidu··on How Fastly coded their own routing layer for scaling CDN
This is awesomely clever. Not surprised to see from the Fastly team.
davidu··on Google rolls out “If This Then That” support for its $200 OnHub router
How does IFTTT make money? I can't figure it out.
davidu··on Stripe: Bring Your Own Team
Like a small acquihire without the acquihire part. :-)

Smart, and super curious how this plays out with teams and comp negotiation, especially vis-a-vis acquihire equity negotiations.

With no investors to return capital or stock to, negotiating as a team should increase returns to the team individuals.

davidu··on Juno to soft-launch this month as the anti-Uber service
"the anti-Uber service" is called driving your own car.
davidu··on Poor New Yorkers Tend to Live Longer Than Other Poor Americans
I came here to say this. The health benefits for the heart and lungs of "active walking" are well established and anecdotally, people in NYC just walk from place to place constantly vs. other cities. Even metros like SFO. It's even worse in places like Atlanta and Dallas where you basically have to drive from place to place.
davidu··on iPhone SE
Wow. +1 for having no idea I could do that. So much easier than the old way of trying to hunt and peck the right spot with the magnifying glass.
davidu··on Atlas and Cuba
This is really incredible.

Many of small actions by a small number of focused people in Washington, in the Whitehouse, and entrepreneurs and bankers, may have a profound impact on millions of Cuban lives in a very short period of time.

Another good reminder (to abuse a quote), "chance favors the prepared" -- Stripe had already laid a lot of groundwork before Atlas to handle the systems required for this, and then they launched Atlas to handle many of the regulatory requirements, and so when this opportunity came along for Cuba, they were quickly able to take advantage of it.

davidu··on A tale of a DNS exploit: CVE-2015-7547
Just a small shoutout of thanks to the CloudFlare team who was excellent about communicating with us at OpenDNS in advance of this disclosure.

As one of the largest recursive DNS infrastructures in the world, they allowed us enough time to spin up resources to determine if we were vulnerable (we were not) which was very much appreciated.

We did a small post this morning that also captures some of the history of our codebase. https://engineering.opendns.com/2016/02/29/a-brief-history-o...

davidu··on The secret lives of Tumblr teens
I didn't mean tumblr is complicated, I meant explaining what tumblr means for people is complicated. It's the ultimate long tail site which means it serves very different purposes for different groups of people.
