Maybe you mean layoffs... Every company should be ready to do a firing if it's required that the employee and the company part ways.

1) How do you know what peering agreements look like? What you write is simply untrue from my experience. I peer with about 200+ networks today. Who are you? Illumin8 me please. 2) Of course DOCSIS works if you reverse the flow. You al

I guess we disagree. I don't find anything you wrote to be very factual. Most networks charge their neighbors -- be them customers or peers. That means when one neighbor sends traffic to another neighbor via the ISP, they both usually pay

This is not what is happening. Comcast is an ISP. Just about every CDN out there pays to peer with Comcast to deliver bits faster and cheaper to Comcast eyeballs. Level(3) is an ISP. Because they carry traffic Comcast customers want they

Actually, you are not returning signed content from your server to an end user. End users are stub resolvers, which are not DNSSEC aware. I believe that should change, as I mentioned previously, but even the DNSSEC proponents pretend to as

I think this is right and what we've heard from users is right. It's actually the same complaint from Uverse customers -- swapping out the ISP-provided CPE breaks their TV service. It seems you've got a work-around. We'd love to update ou

I strongly disagree with the notion that only the zone owner should be able to generate records for it. Nothing else on the Internet behaves like that. And anyways, Paul has changed his thinking since then on this subject too. He now pref

No. tptacek is entirely correct. DNSSEC won't help here. DNSSEC is not exposed to applications the way SSL is and so you will never see widespread adoption. Take Chrome for example. Chrome is in the best position to make use of DNSSEC sin

I'm the founder of OpenDNS. This article is not accurate. We are blocked by Sprint Wireless, not Verizon Wireless. You can't change your DNS easily when using the Verizon Wireless 3G network's provided hardware, but if you are using you

DNSSEC and trust anchors will handle that part. It's more of the name collision issue that concerns me.

by davidu 16y ago
Well, we at OpenDNS could make this work for all our users today. And I think we're large enough that they wouldn't just seize our domain. But it's a slippery slope... Once you fragment the DNS like that, it's hard to go back. And then we

A lot more censorship. Facebook doesn't let you link to sites they don't like. Even in private communications.

The term "reverse" is not the right word to use. What is meant is that you can generate another input for which the SHA1 output matches your other SHA1 output. This is because SHA1 has collisions. So "foo" could hash to 1 and "bar" could

Bingo.

by davidu 16y ago
Actually, you can reverse a SHA1 into plaintext. That's exactly what we're talking about. Can you know it was the same plaintext that went in? No, but as far as the SHA1 output is concerned, it's a suitable input and a suitable reverse. F
827.
by davidu 16y ago
At the very least, add a random salt added to each plaintext before you run it through the SHA1. This will at least defeat rainbow attacks fairly well. That said, you need to do more and move beyond SHA1 since you can now reverse a SHA1 in

You don't have to promote people to show them they are doing a great job. Now, I'm sure Harj wanted the promotion, it's a big win for him, but promotions aren't the answer all the time. There are lots of people who do NOT want a promotion,

Except that you can export the email addresses if you use Hotmail or Yahoo! Contacts, which have special agreements with Facebook. I did this, and even though it's super crappy because it doesn't map to my existing address book entries very

by davidu 16y ago
Not email/phone/etc. And despite this, you can get email via hotmail or yahoo mail contacts integration. It's fairly a hypocritical position for Facebook to take.

Bingo. Fred should link to this in his post today. And furthermore, Fred's points of when it makes sense to have participation rights are dead-on and exceptionally well articulated.

If the investor is valuing it at 5mm, so are you. You are telling the investor that the company is worth at least 5mm. If it sells for 2.5mm, you screwed up. Why should you participate in the proceeds of a sale?

by davidu 16y ago
There is a missing piece from Fred's post, as I often find the case to be. I know Fred's smart, so I'm not sure why he omits key pieces of the discussion. In this case, he is leaving out his views on participation rights. What this means

Granting someone an RSU doesn't put a financial burden on them to exercise. Also, if you leave a company, you often have a short period (90 days) to exercise any vested options. If you have 100,000 options at $1/share then you would have t

Flock was a terrific idea, terribly implemented, and likely a bit ahead of its time. In my view: 1% Idea 33% Team 33% Timing 33% Execution You need all of them perfectly aligned, but that's how I see it.

This is exceptionally rare, and no major email server does this. File systems are reliable, easily scaled and distributed and backed up. :-)

I'm surprised at how poorly planned and filmed most of these videos are. Is that the point? Is it supposed to be so rough? (Note: I've never applied to YC or looked at the application)

DevStructure is a great way for me to sandbox my dev environments and work on projects quickly. Being able to use DevStructure on a VM makes a ton of sense as I don't always want to burn CPU cycles on a cloud server.

I'm not sure why Fred doesn't mention it, but as your option price creeps upwards, it becomes (for better or worse) a form of handcuffs for employees. If your option price is $0.50/share and you grant a new exec 200,000 options then it will

If you are burning $500,000/month, which is not unreasonable, then you get 10 months with $5mm. If you haven't turned the corner after 5 months, you know you won't get out of the hole before you run out of cash. Therefore, you sell the comp
