It's already braindead easy to put Linux on the ARM Samsung Chromebook. One of the first things I did was to assemble my own personal Linux distro and besides having to copy some blob files out of the original ChromeOS image, it's all very straight-forward stuff and I pulled up about a hundred packages I wanted including an X.org stack without fuss. The compile speeds are adequate if you aren't cross-compiling, I've certainly put up with worse.

I personally have little interest in the Pixel based on the specs. I think X86 is excessively 'big iron' now for a majority of needs and I find the lack of USB3 is mystifying. The screen looks interesting, but it's nothing I actually /need/ and certainly not worth another thousand bucks. I've personally taken to just using X86 for storage/cross-compile servers for the rest of my cheap ARM/MIPS/etc. crap and I've made it a point to stop buying expensive hardware. What $250 buys you now is actually pretty ridiculously awesome.
I found this clicking through their slideshow: "Another thing that has changed from past prototypes is that Volkswagen has confirmed that the XL1 will be produced and sold, though only in limited quantities. Sadly, there is no information on price yet, but the limited production probably means that it will be expensive."

But we're talking about something used to surf the web. An ARM is still powerful enough and will use way less power.
I love Tesla as a company, but TSLA as a stock is broken. There seems to be serious manipulation going on -- right before long annual options expiry, the price drops, then pops right after. There was shadiness the previous year related to a drop, then announcing a departure of some mid-level exec, then a pop. I generally stick to options for playing things like AAPL, TSLA, etc. where it will move based on some specific accomplishments, but TSLA is one I own as stock directly.

My wife was in the ER a couple years ago - I asked multiple people (two nurses and a doctor) how much any of this would cost, and they all said "I don't know".
Unless you wanted the gorgeous 2560x1700 display... Many people have paid close to the whole computer's price just for the screen (I'm typing this on a 2560x1440 screen that I paid $999 for).

I think the "saddest" headline is a little tongue-in-cheek and refers to the fact that they're missed connections, so it's a case of people getting "this close" to finding love, but having it elude them.

I'm quite surprised we expect insurance to cover routine medical expenses. We're still paying for them anyway and now there's a middle-man to hide the true cost and take a cut.

It's still expensive, but catastrophic insurance the minimum people should be getting--like you said.
Investors are surprisingly pessimistic. I am heavily invested in TSLA. I got out right before earnings call because CEOs like Elon don't seem to care about meeting Wall Street's expectations. I'll buy more in a week or two when the market is more favorable.

Almost all of the criticism I read of TSLA is regarding their financials. There is a lot of room for sentiment and investor confidence to improve. Things I care about(like Elon's track record & ridiculous amounts of ambition, improvements in battery technology, not using dealerships, the supercharger network, etc.) don't ever get mentioned.

Wall street seems to care about whether they'll be able to meet production goals, the amount of cash they have on hand to continue operations, etc.

Most importantly, as more consumers take delivery of their Model S' I'm expecting investor confidence and awareness to improve. They'll "see" the demand with their own eyes. My father is already mentioning to me that his friends are seeing Model S' pop up around town and people are talking about them. They want to know what it is. It's extremely common for retail investors to buy stock based on products that they see being used.

You're right in that I'm betting solely based on investor confidence improving. In my opinion, there is no other metric on which to price a stock.

It’s Shocking How Much Abuse This All Glass Snowboard Takes Before Breaking
On almost any other topic I'd be the first to agree with you.

But people aren't buying this kind of medical care voluntarily, and that throws a lot of capitalist idealism out the window.

In fact, there are a lot of reasons why normal supply and demand aren't quite applicable for medical care.

Imagine a person having an accident that injures them and knocks them unconscious. They don't pick the ambulance service, they don't pick the hospital they go to, they don't pick which doctors work on them, etc. But they still get the bill for all of it.
> Our biggest error with this was not making one person ultimately responsible for the physical design. Choices need to be made and not everyone’s ideas can be reconciled with each other and the constraints of reality. For a holistic design, eventually someone has to reconcile reality with what everyone wants or you end up with a bunch of individually well thought out pieces that don’t fit together (as well as a bit of frustration.)

That doesn't just apply to server room design. It applies to just about ANY design. Including software.
Stopped traffic. A couple of decades ago, the only road from Silicon Valley to Skyline in the hills was blocked by construction equipment repairing a washout. My wife got out and walked up the line to see what was going on. She started talking to a man standing there. Turns out he was a freelance developer and my wife said, "My son knows how to program.", which lead to his firs job as a programmer in high school. In this case a connection made in stopped traffic.
Well what we really need to continue to improve clock cycles is better cooling. Overclocking modern chips is really easy and all you really need to get a pretty solid increase in speed is a decent cpu cooler. Yes to get drastic increases you need to up voltage to the chip and there are concerns about the chip degrading faster at higher clock cycles, but for the most part a solid increase in speed can be achieved simply by telling it to go faster and making sure it doesn't overheat.

I never understood the concept of missed connections on craigslist. Honestly, what's the chance of two people meeting each other, forgetting to swap numbers, and then both going onto craigslist to search/post in the missed connections category?

It just seems like such an overwhelming statistical improbability that such a missed connection would ever be fulfilled through craigslist, I don't see why anyone would even bother posting.

Sometimes I feel like Tesla is the NeXT of cars. Technologically impressive, but ahead of its time.

In 15 years electric cars will have much more market share, question is, will Tesla still be there leading the pack?

Maybe they can reverse acquire some ailing car company ;)
A sneak peak of ConvertKit
It's slick. It's nice to use. Doesn't fix the decades-old problems with Craigslist - not your fault, the license they sell is incredibly restrictive (basically allows you to make a mobile client for them and pay for the privilege) and explicitly prohibits any kind of innovation.

Converting untrusted PDFs into trusted ones
Yep, that's true. I had a bunch of issues with their 'native' OS X app though. Every now and then the embedded browser (I think that's what they do anyway) would go nuts and eat my whole CPU. Also, the streaming quality didn't sound that great. I regularly use Grooveshark, and the quality of the songs over there was much better.

All in all, I guess it might work for some people. It just didn't make the cut for me. For that matter, neither did Spotify or Pandora. I guess I'm just not the target audience for that kind of service in general.
Amazing work. It's incredible (and a bit scary in a big brother way) to be able to zoom-in CSI-style across such a large distance and still see faces / license plates, especially with mostly consumer/pro-level equipment on an ad-budget.

This is the Tesla roadster. It's an aspirational product for those who can afford it, those who wants to live in a brand new, and not quite ready for primetime, cutting edge world.
I doubt that you can have a much increase in performance as cores increase unless you are calculating numbers with huge amount of bits.
I am not a musician and I don't keep up with production methods too closely, but this method of "load a bunch of loops into your devices, trigger them in interesting manners" sounds almost EXACTLY like what I've read about the way Orbital has been working since somewhere in the early 2000s.

I think the only difference is that the price of these kinds of looping tools has dropped precipitously, so there's more people fooling with them.

(And I am not trying to disrespect the musicianship of people doing this. I'm just questioning it being a NEW THING.)
I'm an engineer at New Relic. A fix for the Python agent will follow within the next day or two.

Asking around, it sounds like only the Python & Ruby agents are affected by the queue time reporting issue (with the exception of Java, which apparently doesn't report the queue time at all -- but I believe this is a known limitation).
What I was really hoping they would release was a marriage of the Samsung Nexus 10 and the Samsung Chromebook (ARM). I have one of each, and if I could get the screen of the Nexus in the Chromebook, I think it would be my perfect laptop (though the build quality of the Chromebook is a little lower than what I prefer, and who doesn't love a backlit keyboard).
I do not see why not if you are motivated enough. I would even pursue 'social coding' on Github. Seek a project out and see if you can contribute? Learn from others after you have the basics down so you can ask constructive questions and hone some skills. Could serve as a mentor of sorts that you are seeking.
I'm incredibly impressed. I was able to see the brand of someone's laundry detergent through a window. I've never seen that type of zoom before one one of these.
Probably for the same reason people play the lottery. The odds are against you, but the reward is worth that little bit of effort.
I wonder if we will ever figure a way to resume improving clock cycles instead of adding more parallelism.

IPC has been steadily improving generation over generation, but it is a slow march. Chip frequency does not seem like it is going to go anywhere without some serious breakthroughs; processors are thermally limited, and while you can work on saving power there don't seem to be any 10x improvements in power coming that could let you crank up the clock. Scaling voltage down is great for reducing switching power, but it depends on smaller and smaller transistors, so leakage power has been steadily growing and eating into those gains.

Chips are up against a lot of walls- power consumption, heat dissipation, and so on. Chip makers have and are working on pushing forwards, but short of a new kind of transistor there do not appear to be any improvements by orders of magnitude on the horizon for single-core performance.

This is why parallelism is important. It is hard, and not every workload can be parallelised well, but there is simply no other known way to secure a 4x, 8x, 16x, etc boost in performance than 4x, 8x, 16x, etc parallelism. (Assuming your code isn't terrible, in which case fix your code!)
Hypothesis: we will never solve multi-core for general purpose computing (there's also http://en.wikipedia.org/wiki/Amdahl%27s_law). But we can do multi-core for the embarrassing parallelizable - such as graphics (top GPUs have over 1000 cores), so instead of solving this problem, our focus will shift to those tasks for which multi-core does work - because it's only these that keep improving at Moore's Law-like rates.

Arguably, this is already happening.
At Blekko we ended up moving 600 servers from one co-location facility over to a neighboring town about 5 miles away. It is a lot of work, and its a lot of co-ordination. When I was at Google I thought they were just being arrogant by designing their own racks, building them and shipping them in pre-built "chunks" to the data center. I was very wrong about that, it saves a huge amount of time.

I look forward to a time when a colo facility says something like "We can lease you 50 OpenCompute 2.0 slots for $3,000 a month" and know that I can just populate the hardware, plug my switches into the structured wiring solution and be done.

Not sure if Colos will last that long though :-)

Web browsing is pretty darn good on the iPad and comparable Android tablets, but it's still a far cry from the performance you can get on x86 hardware. Many Surface Pro reviews mention this specifically. Now, there's still obviously value judgement to be made: is the Pixel worth the extra money, extra weight, and worse battery life compared to an Apple or Android tablet?
He/she may have come off as abusive. But I think that's actually a good question.

Yes, the resolution is great. But why would someone spend 1300 bucks on something that has great resolution just so they can ssh into something else? $500 maybe.
From the blog post, "Tesla stock is down almost 10% today, after its 2012 earnings report became public. Tesla missed its projections and investors hammered the stock in response."

I guess that's what you call contrarian investing. Sometimes that works just fine. Sometimes that doesn't work so well. People who have extra money to buy speculative stocks can make their own call on this, I guess.

I found it interesting that there were many news reports about the Tesla fourth quarter results call yesterday.

So, yeah, some investors will read all that and still bet on Tesla's stock having a rising value over their investment time frame. But customers who are thinking about buying the car might wonder if the company has enough financial strength, while losing money on every car it sells, to provide long-term customer service and the promised completion of the Supercharger network, etc. If it's your money, spend it how you like, but be sure to diversify for maximum safety.

It says that they're planning a small production run of 100-1000, price expected in the € 30-50K range (not the $600 rumored), components are quite expensive, for example a carbon fibre body. My guess would be that they're limiting the production run because they're losing money even at those prices.

He suggests an interesting approach.

1) Tell the kernel it only has a limited set of cores to work with.

The way to fix Snort’s jitter issues is to change the Linux boot parameters. For example, set “maxcpus=2”. This will cause Linux to use only the first two CPUs of the system. Sure, it knows other CPU cores exist, it just will never by default schedule a thread to run on them.

2) Manually schedule your high priority process onto a reserved core.

Then what you do in your code is call the “pthread_setaffinity_np()” function call to put your thread on one of the inactive CPUs (there is Snort configuration option to do this per process). As long as you manually put only one thread per CPU, it will NEVER be interrupted by the Linux kernel.

3) Turn off interrupts to keep things as real time as possible.

You can still get hardware interrupts, though. Interrupt handlers are really short, so probably won’t exceed your jitter budget, but if they do, you can tweak that as well. Go into “/proc/irq/smp_affinity” and turn of the interrupts in your Snort processing threads.

4) Profit?

At this point, I’m a little hazy at what precisely happens. What I think will happen is that your thread won’t be interrupted, not even for a clock cycle.

Can anyone remove the haziness? I'm more interested in this for benchmarking than performance, and wonder how it compares to other ways of increasing priority like "chrt". Is booting with a low "maxcpus" necessary, or can the same be done at runtime?

Not even remotely true. Super high pixel density screens are an unalloyed win. Everything you do on one looks better, most particularly, text rendering, which is absolutely superb on my rMBP. I would expect Google's screen to be comparable.
