Great post! I think there does need to be some very introspective reevaluation of commonly accepted technology hiring processes. Obtaining negative signal solely from firing decisions disregards the many other sources of information that ca

Once again, awesome analysis. Highlights for me - great breakdown of timespent/adspend per medium showing huge potential for ads on mobile and overspend on print - the tablet/phone boundary is being stretched by Korea with very lo

Articles like this just reinforce stereotypes (women as victims) without recognising the reality that men can also be victims (of male or female abusers). This makes it even harder for men who are victimized to come forward. There are plent

It's really sad that this isn't clear. CSS was intended to be simpler than DSSSL but ended up being more complicated, harder(?) to implement and immensely less powerful. One thing that could work well would be to implement layout

The technique described takes a low quality sensor (a DRAM chip with an open window onto it) and uses it to produce reasonable quality grayscale images. Interesting to look at the sourcecode of the Kuckoo program (before the widespread adop

This methodology is flawed, because in practice the conversion rate changes over time. There are different effects that cause this temporal dependence not including the natural effect on the product of certain techniques (for example testin

The cost of switching is generally very low and it's quite likely that most people with data in the UbuntuOne system that they wanted to keep were already using another service like DropBox simultaneously. The biggest cost here is to t

The disk is almost certainly not idle, but instead the iops are consumed by read traffic. Ideally, the kernel would know the deadline by which the data should be committed, manage accordingly, and the fsync would be simply acknowledged rath

If this is what passes for an apology from Ars Technica for wrongly reporting on this story from the start, when I believe it claimed that this was free Photoshop for the masses, it is a weak apology. A news organisation should stand behind

Dependency injection subjugates readability and simplicity of data flow for a narrowly defined notion of testability. Even in languages like Java, it's possible to substitute class definitions for mocked ones without having to thread a weir

Consumer flash cards are an example of a market where the purchaser has very little information to go on. The raw user available storage number is pretty misleading as the block remapping system (or absence of one) is a key determinant of r

The link between broadband and apps is tenuous at best. The US has lagged in consumer broadband behind most other countries for a long time. It also lagged in adoption of text messaging and so on. This is presumably due to the weird regulat

I agree that browsers should make it much clearer that clicking on a button or link which does nothing is having no effect. In my mind this violates good UI design: that whatever action the user takes, they deserve some feedback. There are

Hashtables are great until they grow to a significant fraction of available memory. Then there is no way to avoid the cost of rehashing or giving up constant time access - and if your program isn't using most of memory then you can run it o

It is not sensible to hire people who will become rapidly frustrated at the function they are delegated to perform unless you have another position to promote them into. Often you need someone to perform a dull role. There are plenty of peo

Siqi hadn't agreed to share his entire life with his YC cofounders and pretending otherwise is very childish. The fact that PG is being upvoted for this simply because he is PG is damaging to reasonable debate.

It was easily measurable if you ran the instructions in a loop and looked at the power draw. I can't remember the numbers now but it was definitely significant (maybe 30% on a wide vector instruction?). I don't know where you got the idea a
