Vinod Khosla is quoted as saying: "This is a question only writers like. Who cares whether [startups are] overvalued or not?"

Lots of people care:

- Potential startup employees who need to evaluate a compensation package that contains equity.

- Investors in venture capital funds.

- People who are thinking of buying stock in these companies if they ever IPO.

- Larger companies who are considering acquiring a startup.

If someone is trying to pretend that the valuations of startup companies is an irrelevant question and that journalists should stop investigating the phenomenon, I'd suspect they're trying to hide something.

Assuming that the price of something can only go in one direction (up) has repeatedly caused a lot of pain to people and to the economy over the years (the last and biggest example of this was the housing bubble). And having been an investor during the 1999 internet bubble, I can definitely see similarities between then and now. I don't know whether we're in a bubble now, but it's not impossible.

Why not "improve education and rights for people globally"?
I agree in the sense that the living projection is unnecessary (I use Void theater.)

I do have to mention that VR + headphones will definitely take my mind out of the flight in a way that a screen held in front of my face doesn't.
Modafinil user survey (2015)
I'm trying to bring it back.
Facebook is flexible enough to provide this.
You can post updates visible only to a group of people.
Problem with Facebook is how people use it. Users tend to have > 500 friends on an average including ones to whom you have never spoken or never want to speak. This would make your timeline pretty irrelevant and uninteresting to you.
Why would I care if a colleague in your first job (10 yr ago) went on a trip with his childhood friends.

Take a scrub to your Facebook friends list and you can get a more powerful TinyLetter.

Practically speaking you'd never un-friend people unless they personally bother you. This is why I hardly check my Facebook timeline. All I use is Messenger which is pretty useful to keep in touch with people you want to.

So, the real anti Facebook is Facebook itself with a fresh start.

I researched the 410c schematic as suggested by tbr. I can measure the input voltage at J1 and measure the input current as a voltage across the .1Ohm resistor r77 or pads 1 and 2 of j10 (both on the bottom side of the board).

Idle, text 15.2v 115mA 1.75W
Idle, X 15.2v 124mA 1.89W
1CPU, X 15.2v ~180mA 2.74W
2CPU, X 15.2v ~240mA 3.65W
4CPU, X 15.2v ~260mA 3.95W

All of my CPU loading scenarios had much more variable current readings, I tried to record the highest value I saw on a multimeter with a ~.5s update time over 10+ seconds.
I read Chris Lattner's posts. There are definitely things the standards don't specify that people take for granted (twos-complement for example). C is still an order of magnitude easier to parse than C++ though (especially modern). In theory, implementing and maintaining a compiler for it for a platform should be simpler.

Implementing an effective compiler is another concern entirely, but I would still argue that there tend to be more incompatibilities between C++ implementations than C.
Curing Aging with Telomere Lengthening; One Year Away from Human Trials
Was hoping this touched on Z-ordering. If you have a processor that can efficiently interleave bits (i.e. combine 0110 and 1011 to get 01101101), you can lay out 2D and 4D arrays in Z-order, which will improve spatial locality (nearby elements in both the X and Y dimensions are also nearby in memory/cache/TLBs).

You can actually efficiently achieve this even on processors without an interleave instruction if you're only walking stepwise -- basically, mask out the odd (resp. even) bits separately, setting the even (resp. odd) bits to 1 before adding 1, or to 0 before subtracting 1, then recombine.

> Redis in its special case of memcached replacement, may be addressed executing multiple processes

This is always less optimal to a single process. Simpler is better.

> Redis is very very observable

This has a cost...trashing your phenomenal read and write performance. Running a concurrent redis, just for monitoring, is a hack that I have used to continue leveraging the observability.
Ashlee Vance appears to be a man.

https://en.wikipedia.org/wiki/Ashlee_Vance
that is a very nice hack. this kind of 'do as much work per standard library call as you can' approach is pretty much the way to go in interpreted languages like python or octave, which is in part why numpy is so popular — not only does it allow you to program at a higher level of abstraction, it also makes your program run more efficiently.

however, i think that technically, that's not an A* search he implemented, just a breadth-first search. i'm not an expert (i've never even implemented A* search), so i could be mistaken. i'm interested to hear whether other people agree.
Also, you need to cough up $10000 p.a. to become a supporter and be invited to join the sessions...that leaves many a good idea/thinker locked out.

The Silent Season of a Hero (1966)
This is a really good blog post. I find it very neutral even when the author happens to be the one who created Redis.

What I really like about both pieces of software is that they are dead simple to set up. If I were to make a decision today for new projects who are just starting to scale I'd probably take a good hard look at redis and see if you don't need any of the extra features. I could see a lot of projects eventually needing those features and leveraging redis. I really like the pub/sub feature in particular. Persistence is always nice if you don't have to pay too much for it.

Does anyone know if amazon has a redis/memcache service? I can never remember what they name things.
It's hard to make a compelling argument for why a particular problem will never be solved. However, I think it's a reasonable supposition that such unsolvable problems exist. Resurrecting the dead, for instance. In order to faithfully simulate the universe, you'd apparently need complete understanding of the laws of physics. And, you'd probably need a tremendously large (and presumably very power-hungry) computer to run the simulation. There's no particular reason to think that physics will ever be completely understood, and the computer might need more power than all the stars in the universe can supply.

Again, it's extremely difficult to argue compellingly for why something can't be solved: even if it seems to be ruled out by known laws of physics (like traveling faster than light), you can always argue that new laws will be found someday that will be more favorable than the current ones. That argument never terminates, because you don't know what you don't know.
One thing though about Evernote I wonder. Where are they spending all of their hundreds on millions of dollars? I haven't noticed the software changing basically at all during my using it... Well don't fix it if it isn't broken...
I think Jason's wrong about self-driving cars being so "refined" and different from the core Google ad business. I see Google eyeing Tesla not for its zero-emissions, electric vehicles, but for its always-on, always-connected vehicles. I believe Google, whether they realize it or not, views cars as a gigantic new market for hyper-personalized, hyper-local, just-in-time advertising of a sort we have never seen before. While you're driving. The car, and by extension, the cloud, know where you are. Which means everything paying a fee to the Google is gonna know you're passing by right now, or about to. You really think Google's not going to enable that kind of advertising? "You're one mile from a great burger at McDonalds." "Hey you're about to pass a great sale going on at Lenscrafters. Stop by in the next 5 minutes for a 20% discount." "Hey there Claire, you have 87000 miles on your Celica. Turn right in 500 feet and stop by Bob's Toyota for a fantastic deal on a trade-in right now." Et cetera. It is coming. It is going to suck. Advertising is coming to cars and it's going to get ugly. And I fully predict Apple wants to get in on this game too. Just watch. It's coming.
Right now, I prefer movies on GearVR to a home-theater system with full HD on a fairly close and large TV. For 2D content, the resolution isn't great (a little over 720p effective), and there is a very apparent "screen door" effect.

In terms of 3D, I watch people's minds get blown by simple apps, when much better stuff is in development. When my Mom asks, did I bring that funny headset so that she can see Paris again? this is something different.

This will be really great with 4K displays and improved content.
There's a quote attributed to Rutherford that “In science there is only physics; everything else is stamp collecting.” (See http://www.quotationspage.com/quote/26219.html for a citation.)

When I was in school we had to learn the organs of the body, the parts of a cell, and other seemingly arbitrary terms. This comes from an old tradition where "science" was roughly equivalent to "knowing names."

I also grew up in an area where evolution was a contentious topic. The teacher only covered it for one day. But it's evolution which tied together the individual fields of 'botany' and 'anatomy' and 'bacteriology' into 'biology.' Evolution is what makes Rutherford's views wrong.

Words like "supermoon" and also "blue moon" fall into that category of meaningless terms that sound scientific but are little more than numerology, and not backed by any deeper meaning.

I have no problems getting together for a 'fun celebratory event'. I celebrate on New Year's eve like many others. I've been at fun celebratory events for meteor showers, and for other eclipses.

What I have problems with is justifying it with essentially an arbitrary and meaningless definition. Why is a "supermoon" at the 90% size threshold? Why not 95% Or 99%? By comparison, the New Year is also arbitrary, but not meaningless, as the history of the calendar shows.
This is the attitude that is frustrating.
Should the net be free of censorship? Of course.

But the dismissive attitude of some of the absolute vile garbage that is online is annoying. It isn't "some degree of harassment" it is god awful. Easy to be dismissive when you are not subject of something. Women by far are the target. A tad more empathy instead of dismissing something with the attitude their complaints are some needlessly whining

I remember thredis very well! But it's different compared to what memcached does and Redis has plans for: memcached just threads the I/O part, not the access to the key space which is serialized via a mutex. However what you had in mind is also in our long term plans... and was addressed in another blog post here: http://antirez.com/news/93

I think you should list all the flaws of I2C and SPI and say if PJON also suffers from them:

* How easy is mixing 3.3V & 5V?
* Can I always program the address of a slave? (If not, how do you resolve address clashes?)
* Can slaves initiate communication?

etc.
Absolutely not, it's the memcached model. There are N threads (like 4 or 8 or one per core) serving all the clients in a multiplexed way like is happening now with a single client.

If we'll go the extra mile implementing also background slow operations, we'll send them in another "ops" thread, will block the client, and will resurrect the client and send the result when available. Like we do currently for blocking operations like BLPOP.
> There’s growing evidence that hiring a top sport programmer is a coup for software companies.

So, hiring people who engage in doing something as a hobby and practice at it outside of (or in addition to) regular "schooling" do well? Whodathunk? We didn't even have programming classes in my day (well, not until 9th grade for me, and that was pretty advanced - many neighboring school districts didn't offer any at all). (edit: so... for many years the only people I knew who programmed were all hobbyists/extracurricular folks)

> “Every time I have hired someone who is good at these contests, they have crushed the job. They tend to be fast, accurate, and into getting things done.”

Wondering how well people like this fit in to team-oriented environments. I'm certainly not a programming-olympian like the subjects of the article - have never done competitive stuff (did "olympics of the mind" back in the day, but not quite the same thing). However, I think I'm a reasonable problem solver and software developer. I don't typically fit in well with teams. Do the benefits of these 'super-coders' outweigh any diminished team capabilities? Is that a tradeoff that can be made for a season, but needs to be rectified later?
no implicit type conversion is just one of several strongly typed properties. type checking & safety weigh more to label a language as a strongly typed one.

if you abuse your body with bad food and no exercise, you tend to be skinny and weak when you're a teenager, then dumpy and overweight when you get old. brogrammers exist but mostly aren't good enough to compete in programming contests.
Traffic jams spontaneously occur before roads reach theoretical capacity. You should look up information yourself on that if you're curious (because offhand I'm not sure what to search for).
I wrote a small script to solve the easy ones in the browser: https://github.com/rhnvrm/30s_challenge

and here is the cheat: https://github.com/rhnvrm/30s_challenge/blob/master/cheat.js

Also, I found that since the methods of the game and challenge class are public, you can actually just call it's functions. I also found a useful resource for learning OOPs in js http://phrogz.net/js/classes/OOPinJS.html and how to make methods private. There is another cool article here on how to make members private and protected here http://philipwalton.com/articles/implementing-private-and-pr...
This is so easy. Let the market decide. If such censorship is so fucking great, let a new startup create a censored social network and see if all the downtrodden people of the world flock to it, or see if they prefer to stick with the rest of the world in the places where they may speak freely about their own pet issues.
I assume it's the result of our brains being better able to make a size comparison when the moon is at the horizon.

Here's an example I shot two full moons ago: https://www.flickr.com/photos/aaronbrethorst/20189872605/in/...

The moon looks absolutely monstrous here, but, I expect that if I had measured it when it was high up in the sky, the actual apparent size wouldn't have been any different.

Did roup edit his comment after you replied? I see no mention of Vance's gender in his comment.
Sure, but that doesn't change the fact that you cannot implement anything at all that accepts more than a regular language. In practice, however you implement it, you will have only implemented something equivalent to some finite state machine (due to the finite memory available to you).
They do - ElastiCache. And as it happens, you can choose either Redis or Memcached!
Comilion to Discuss Privacy by Design in Cyber Information Sharing at IAPP
an interesting thing about programming competitions (in general, and icpc in particular) is that they select for winning hacker teams, not winning hackers. if your three-person icpc team is even epsilon more productive than you would be on your own, then you will beat any single-hacker team that consists of someone just like you. icpc is especially team-focused because you only have one terminal, so you can't just each hack away on different problems.

so selecting for programming-contest winners might be a good way to find super-coders who don't have diminished team capabilities.
As a society we have the prerogative to balance values like freedom from harassment and free speech. I fall strongly in favor of free speech myself, but nobody has to learn to get comfortable with something they find objectionable. Democracy means that people get to live in the society they want to live in.
Maybe what's needed is something that _looks_ superficially like a social media site, but under the hood is just an email system, using the tried-and-true email protocols, maybe with white-lists enabled. Basically, you're not "friending" someone...you're adding him to your white list.
Point 1 is true for me as well. But I take a different approach in doing Point 2.

Since everyone has a gmail account (at least my target audience) and hardly have any activity on G+, I created a G+ community with just the right people and post updates there. These updates automatically send notifications via email to the community members.

The way content is organized and presented in a community is much better than email IMO.
Of course everything can be translated to email - comments can be reply with text and likes/+1s can be reply with +1 - but looking back, it is a much better user experience to do this in a community/group rather than email.
it seems like he made a good choice by shunning ashlee vance, the reporter who wrote this article.
This. Completely agree.

Once I had a conversation with a female designer who organizes "Design hackathons" who said that she "gets disrespected on a regular basis" during meetup with "male participants." I actually agree with her on that point and can empathize with her.

However later on, she went on in a different context of conversation, to discount someone in her coding school program and justified how he is fast learner by his background: "he is just one of those computer nerds" and derided some job opportunities the group was discussing as some "stupid code monkey job".

IMHO, American society's left coast isn't progressive nor liberal but wants to feel progressive. I attended a extremely liberal and elite school in New England, and everyone on campus said the right things and some even did the right superficial things - but when it came to most sensitive things, dating/career/loyalty, everyone instinctively reverted back to the most base human tribal instinct.

In my early twenties, I used to feel upset and somewhat betrayed by my sullied idealism. But I got over it and realized that I am not special snowflake, and whatever difficulties, prejudices against me is nothing in context to other people's in history, better time could be used for me to learn and better myself (than sulking and railing with the "misery loves company" "social justice warrior"/"MRA"crowd on Facebook); and accumulate skills every day.

The same people who think a person is "just a 120lb nerd" or a "dumb jock" will be the same crowd that will "like" Facebook post about a "Science is Cool" post about a paper that the said nerd publishes later on, and likewise for the "jock"'s accomplishment dumbed down for the social media format. Hence people's need to "feel good," and need to not want to "feel bad" during the years it takes to be actually "good."

Thanks for the run-down, esp. the mention of the CPU fan, as I had noticed it in one of the photos. I'd be interested in reducing clock speed in the hope that I could get rid of all the fans (maybe use a heatsink?). The available RAM and lack of GPU are major benefits, and I hope we see more products with those features. Cavium seem like they could offer something similar, but I don't think their sales model fits with widespread availability of dev kits.

Edit: Their site and sales sheet have a discrepancy about power supply. Does the dev kit come with one, and what are the specs? Thanks again!
