hershel··on Sony develops new 185 TB storage tape
They probably had the tech working, and some patents registered than(i've seen something similar in disk drive tch).Probably didn't release due to commercial reasons.
hershel··on Volvo’s first self-driving cars now being tested live on public roads in Sweden
It's not a good comparison: flying vs driving have totally different response times(minutes vs seconds). One could even say people can't respond in a good way in seconds , unless they keep full attention at all times, which beats the purpose of self driving cars.
hershel··on Startup School is going global
I wonder , is this a part of an effort to scale YC globally ?
hershel··on End of Moore's Law: It's not just about physics
Who knows. How can anybody tell if 28nm if more cost effective than 28 nm when it isn't sold in the market as a fab ?
hershel··on End of Moore's Law: It's not just about physics
Asics can max out at about 1000x , and zvi orbach has a recent column talking about how to make an fpga with 50% efficiency of asic.

hershel··on End of Moore's Law: It's not just about physics
The fact the we can't manufacture transistors cheaper doesn't mean we won't see big jumps in compute value.We could seem improvements from fpga's(500x max),approximate computing(100x-1000x), packaging(3x-10x) or the radical option of analog computing(6-9 orders of magnitude for brain simulation etc).

Also, there's still huge amount of value to unlock from software, interfaces and the rest.Just look at the iphone where most of the value comes from a great touch interface and an app store. Moore's law is just a bonus.

hershel··on Why washing machines are no longer built to last
In many white goods, miniaturization to the level that prevents repairs are not necessary.
hershel··on Why washing machines are no longer built to last
I wonder how are Chinese white Goods, since the market is new, manufacturers are quite new and consumers are clearly interested in saving money and in durable goods.
hershel··on Why washing machines are no longer built to last
It's not just statistical bias. We know things today are made from cheaper materials(plastics instead metal in washing machine) for example, and it makes sense they'll be less reliable.
hershel··on Neurogrid: Stanford circuit board simulates million neurons and billions synapses
This talks about offering simulating millions of neurons and the interactions accurately. But since Google's famous cat experiment and further work succeeded simulating 10 billion of neurons(with a simple model) on a small number of Gpu's , it raises the interesting question: has someone been able to show any interesting benefits of accurate simulation ?

This could be a starting point

hershel··on Facebook introduces Anonymous Login
I'm pretty sure that in the background they use some kind of data mining to learn you're identity, and they're pretty good at it since they have all this data.
hershel··on Google's POWER8 server motherboard
In the link here they estimate the price for a single power8 cpu at $5000, based on real server price.

hershel··on Google's POWER8 server motherboard
Another possibility, with the power being open and having a market in servers is easic which offers chip manufacturing technology that is fit for lower volumes, with easier customizability option, to offer a customizable server processor.

In the places this fits, it could offer substantial improvement. for example 10-100x performance/cost+power for in-memory cache servers.

And they're working on making this tech programmable while still keeping this same cost levels.

And all this in the context of moore's law grinding to a halt. So definetly ,intel will have a hard time ahead.

EDIT: it appears that the power8 support an open extension interface to other chips(CAPI). Which means will see such accelerators sooner than later.

hershel··on Ask HN: Best language to learn for a Harvard MBA to prototype his own sites?
There was some book about building sites/businesses without coding. There's also drupal which can do quite a lot without coding.

self driving cars will probably be a "winner takes most" market. Google has a chance.
hershel··on Comparing Low-Power Wireless Technologies (2011)
Great summary!

One question: how well does 6LowPAN support low-power(6-12 months on a battery) combined with low-latency(1-2 sec) ?

hershel··on Toward an open Internet of Things
Isn't lower cost reason enough ? and what about new customers(and the side effects they carry for marketing and other stuff) ?
hershel··on Toward an open Internet of Things
That's wrong. The assumption is "even great products can get copied, and than profits go to hell.".Lock-in is one of the rare strategies that work.
hershel··on Toward an open Internet of Things
> There simply are not protocols around that deal with buying a device from a store, taking it home and magically making it work,

There are currently a few such protocols in the works(some still in development, some are starting deployment),highly optimized for the IOT: sigfox, semtech's lora, and the weightless standard.

In general they are low bandwidth, long range protocols(from 1.5 kilometer in dense urban environment to tens of kilometers with direct line of site), mostly use unlicensed bands, use very little power(end user devices might last 5 years on a single battery), enable good latency, and are pretty cheap(around 1 euro per year, maybe less.).

> self describing protocols

It's hard to see that happening on the device side, but having the self-description added on the cloud/router would work.

hershel··on Capital Man: Thomas Piketty is economics’ biggest sensation and fiercest critic
It's a decent argument, and the arguments about lower taxes and increased innovation sound sensible. But as I said, some high taxes countries are quite innovative.

And in the end, the role of innovation should be to help people and equality, safety net and the like have great value for many. On the whole it's hard to argue social Democratic countries offer a worst deal for people than capitalism.

hershel··on Capital Man: Thomas Piketty is economics’ biggest sensation and fiercest critic
Yes, even in non-equal societies people benefit greatly from innovation.But if innovation is not dependent on extreme capitalism , why attribute it to capitalism in this discussion ?
hershel··on Capital Man: Thomas Piketty is economics’ biggest sensation and fiercest critic
The norwegian countries(and maybe france) seem to indicate innovation would still happen in more socialistic countries with high taxes.

Tools to reduce distraction in doing research on the web.
hershel··on Ask HN: Idea Sunday
One of the biggest problem in the new field of medical apps is lack of verification: how do i as a doctor or patient know if an app works, and how well ?

Of course this problem is generic for many types of products.Reviews are a partial solution ,but it would be quite useful to have a site that gathers research and helps in creating valid research on various products.

hershel··on Ask HN: Idea Sunday
Mio does look similar. the whole point is make it easier to carry it inside the bottle - less hassle, less forgetting, less things to carry.

Even better would be integration inside the reusable bottle cap such as you just press somewhere to flavor a bottle.
