computer problems

There are only two hard problems in Computer Science: cache invalidation, naming things, and off-by-one errors.

All problems in computer science can be solved by another level of indirection, except for the problem of too many layers of indirection.

a rose by any other name

someone is calling his pile of poo a rose..

"Cold emails are not the same as spam. Pay attention to their differences, and write cold emails, not spam."

OED - Irrelevant or unsolicited messages sent over the Internet, typically to large numbers of users, for the purposes of advertising, phishing, spreading malware, etc. - Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it.

spamhaus - An electronic message is "spam" if (A) the recipient's personal identity and context are irrelevant because the message is equally applicable to many other potential recipients; AND (B) the recipient has not verifiably granted deliberate, explicit, and still-revocable permission for it to be sent.

by the way, a nice kettle , and a Free travel booking system..

a/b testing

... One of Zulily’s core competencies is its content-management system, ZuStudio, which is designed to aggressively A/B test—or rather, A/B/C/D/E/F/G . . . test—everything you click, from the types of products that show up at the top of your website, to the kinds of photos that you and your family might identify with, to which photo angles might perform better than others.


Zulily’s audience might not realize it—in fact, most don’t—but every consumer-facing experience, whether it’s on, on the mobile app, or through the daily email, is personally tailored down to a granular level, in real time. For example, if you have an 8-year-old boy, and you sometimes buy him clothes, Zulily’s algorithms won’t show you dresses for 3-year-old girls. What you see on your screen is engineered to be as close a proxy to you in real life as possible. This kind of one-to-one personalization is constantly being refined: Based on the way you browse, the software can infer the age and gender of your children; what kind of pets you have; what size you wear; and even whether or not you shy away from gluten. Like Amazon, the site is designed to feel intensely personal for millions of people. "We’ll have focus groups, and moms will say, "I’m your perfect customer, because everything you launch is exactly what we like,’" says Vadon. "Well, yeah."

These multivariate gains aren’t huge: Typically the change hovers between 0.2% to 0.4%. Yet those fractions of percentages add up, particularly when you consider the sheer amount of content Zulily publishes every day. It is fluidly adaptive. Like snowflakes, it’s never the same for any two customers.

Running millions of these tests every day is, in Zulily’s estimation, one of its core advantages in online retail, helping its buyers attenuate to the fickle needs and wants of moms as their children grow up. Children’s clothes, for example, are no longer Zulily’s biggest-selling category; now it’s womenswear. It has been an incremental evolution that would not have happened thanks to Zulily's enormous trove of buyer data. "The other week I was talking to a scientist about their research cycles and why they use flies for testing," says Cavens. "It’s because they multiply so fast! The life cycle is so short, that they can do a lot of testing."

If a penny was donated for every pf or OpenSSH install..wither GPG?

From: : * If $10 were given for every installation of OpenBSD in the last year from the master site (ignoring the mirrors) we would be at our goal. * If $2 were given for every download of the OpenSSH source code in the last year from the master site (ignoring the mirrors) we would be at our goal. * If a penny was donated for every pf or OpenSSH installed with a mainstream operating system or phone in the last year we would be at our goal.
