Make the drawing area bigger! It's extremely hard to write signature fluidly in tiny area with digital devices.

The industry term is NVM, which refers to all classes of non-volatile memory, typically high density ones. How do you like Crystal Ridge?

This is anything but minimalist. Why do I need a slower plugin manager that requires editing .vimrc to enable/disable plugins, when a couple of simple shell commands is faster and less error prone? vimenable() { mv $VIM_DISABLED&#x

There is little reason to use non-crypto hash these days, given fast crypto hash like SipHash.

FLP/CAP merely illustrates the fundamental trade-off between "safety/consistency" and "liveliness/availability" of distributed systems. There is a spectrum of design choices between strong consistency with

This is wrong as well. VMware standard and distributed virtual switch is in hypervisor kernel.

"Virtualization doesn't really add much of anything for that specific problem other than increased context switching and slightly lower performance." This is BS. What if you have 3 physical servers with 30% utilization? DRS c

Always love the practical hardware designs from these guys. I'm also interested in some software stories: Linux kernel/distro used, issues encountered/solved etc.

Open floorplans are great for hackathons and bugfixes for system integration in fire-fighting mode. It's disastrous for actual feature implementation.

Whoever downvoted me, please provide reference. AFAIK, there is no weakness found in Z-Wave protocol itself but a specific implementation in a specific brand of lock, which is demonstrated by the z-force hack. The "just like SSL"

Well, locks are special beasts due to the security command class, which requires extra challenge/response round trips. My VeraLite-G (the cheap $135 one) is more than 50ft and a couple of dry walls away from the door and the overall la

I'm saying that you can put together a better (customized) system than Nest with these parts without relying on any external services.

I was partially being facetious. This article is about a Rube Goldberg-esque API and this site is about hackers. I'm just pointing out that it can be done cheaply with better flexibility and precision by hackers like me. I'm one o

Yeah, just like SSL :)

Trivial and cheaper (for more thermostats/sensors) to do with $80 z-wave thermostats and one Vera* controller with no external service dependency. Nest is $250 each. Ouch.

A motion/temperature sensor from Monoprice: $30. A VeraLite-G (eBay make an offer): $135. A Z-Wave thermostat (2-gig CT100 that can display humidity on the main display): $80 (I got a couple for $62 on sale) No dependency on Google to

Nest is reinventing home automation badly, IMO. You can already do all that and more with plethora of Z-Wave devices with Vera* without any external services.

by vicaya 13y ago
If you actually read the link you mentioned, Internet connectivity to Nest (Google) service _is_ required to make any changes (control) remotely. Why would people buy a $250 to use as a regular thermostat? I'm not opposed to Internet c

by vicaya 13y ago
I personally will never buy a Nest or any home automation devices that _require_ any external service(s) to control and function. OTOH, I'm probably not part of the target market, as I'm perfectly happy futzing around with Vera* a

Anybody here tried this at all? I tried to get a takeout with my emails several times, all I got is on 2.3MB errors.html, telling "service cannot retrieve this item" over and over again.

This _could_ be another case of premature optimization, as gcc 4.9+ could automagically devirtualize non-overridden virtual functions. icc could do that for years.

For reads, sure. LSMs are optimized for writes, while LMDB, which is a nice B-tree implementation is optimized for reads. LSMs are getting popular because it's harder to scale durable writes than reads, which can be handled (in many ca

Would appreciate a comment from whoever down-voted. I recognize/appreciate the effectiveness/power of story telling, especially to convey intangibles/teachings. I (maybe others too) just have an aversion to the story telling

OTOH, whenever somebody tries to tell me a story, I know (s)he's selling something and automatically get turned off. I suspect that the story trick (as all tricks that appeal to anything other than critical thinking) will backfire soon
